Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an assembled element,

The invention relates to a composed element, and to a corner connection applied to the assembled element.

More specifically, the present invention relates to an assembled element comprising at least two panel-shaped elements which are mutually coupled, each of which can be mutually coupled at an angle, whether or not an intermediate member is used. Herein, regardless of the field of application, the present invention is also applicable to the case where, regardless of the field of application, whether or not the assembled element is made substantially of panel-shaped elements, or whether these panel-shaped elements form only a part of the assembled element, To an assembled element of any type including panel-shaped elements.

Although the present invention can be used in any application field, it is a primary object of the present invention to be applied to a furniture field having built-in furniture as well as a built-in furniture such as a closet, a partition and the like.

More specifically, the present invention is directed to connections between panel-shaped elements, wherein the panel-shaped elements can be realized smoothly and used in furniture that is sold in disassembled form and assembled by the purchaser himself . Here, the present invention relates primarily to so-called flat-pack furniture.

More particularly, the present invention relates to an assembled element comprising two or more panel-shaped elements, wherein each panel-shaped element is in the form of a profile in which the engagement portions each extend in the longitudinal direction of the respective engagement region, Each of which includes a coupling region present in the form of a tongue and a groove, wherein the profiles allow the panel-shaped elements to be joined together in a locking manner and at an angle. Such assembled elements are known in particular from DE 20 2009 008 825 U1. The use of such profiles, which are provided in the elements of the panel-shaped elements themselves and in which the whole or a major part thereof is integrally formed with the elements in the form of panels, The separate elements for connection are unnecessary, or at least the use of such separate elements can be limited to a minimum. Another advantage of this is that such profiles can be milled in a simple manner with panel-shaped elements and that continuous locking engagement can be realized along the entire corner connection.

It is clear that such bonding is not only during bonding but also after bonding. Considering that these profiles are in fact most often implemented with relatively thin panels and are also often suitable to be realized as particle boards that are also known to be vulnerable, the known profiles provide only a limited number of choices for optimization do.

Accordingly, the present invention aims to improve assembled elements of the type described in DE 20 2009 008 825 U1.

To achieve this object, the present invention according to a first aspect is an assembled element comprising at least two panel-shaped elements, wherein the panel-shaped elements are fixed by a locking tongue and a trough connection directly, And the connecting portion can be provided on one of the panel-shaped elements, on other panel-shaped elements, or cooperable with a groove or tongue provided on the intermediate member A tongue or groove; The tongue comprises at least a first portion and a second portion, as well as a split tongue having a slit located between the first and second portions; And at least a locking portion is provided on the outer side of the first portion and the slit, when viewed in cross section of the tongue, comprises at least one side portion and the orientation of the side portion as viewed in cross section is biased from the main direction belonging to the tongue Lt; / RTI > By using the slit, at least one side of the slit has a deflecting orientation, and the advantage is obtained that a new parameter is created which provides new choices for optimizing such coupling.

In a most preferred embodiment, the second portion of the tongue has no locking portions. This allows the tongue to always fit smoothly into the groove in the second portion, and optimization of engagement and locking can be realized substantially alone through the second portion. According to a variant, the second part of the tongue actually comprises a locking part, which is less noticeable than the locking part provided on the first part of the tongue.

According to another preferred feature, the tongues and grooves can be pivoted, the corner portions of the fulcrums at which the tongues and grooves can be pivoted relative to each other form an inner corner, and a first one of the two portions of the tongue, Is located closest to the part. This allows smooth engagement by turning motion.

More specifically, the tongue is preferably positioned eccentrically with respect to the panel-shaped element provided with the tongue, or with respect to the panel-shaped element to which the tongue is joined, preferably as in the direction of the inner corner portion described above. Due to the eccentric arrangement, the tongue can be kept farther away from the outer corner portion, thereby allowing more material to remain available in the outer corner portion, resulting in a stronger structure at the outer corner portion Thereby reducing the risk of breakage of the material portions. The eccentric arrangement towards the inner corner portion also allows the tongue to pivot more smoothly into the groove.

According to another preferred feature, the tongue is configured such that the first portion of the tongue projects further than the second portion of the tongue. The advantage is that in this case the first part provides sufficient space for the locking part, while the second part allows for more smooth movement and / or allowing more material to remain at the location of the groove It is kept smaller.

According to the present invention, it is preferable that the side portion of the slit located on at least the first portion has an orientation that is deflected from the main direction described above. This allows the features of the first part of the tongue to be influenced not only in elasticity but also in strength, and in this way the advantage of creating new parameters for the design engineer to realize the desired combination of functions of the result . This is very important for the first part of the tongue, since the first part of the tongue contains the most important locking part and its stability as well as its flexibility as well as its stability determine the good function and strength of the engagement. More preferably, the inwardly facing side of the slit described above preferably substantially approaches a plane defined by the surface of the panel-shaped element located on the same side as the first portion of the tongue. This allows the end of the first portion to remain relatively strong and strong, which is beneficial for the strength of the locking portion provided on the first portion, while a higher elasticity is produced towards the inside, It is found that the first part and the associated locking part are important for producing the appropriate elasticity that can be displaced. In this way, both properties are determined on two different positions by the general technical shape there, so that the designers can also benefit independently of these characteristics.

According to the present invention, it is obvious that the side portions of the slits located on the second portion irrespective of their combination with the preceding second features can be provided with an orientation that is deflected from the main direction described above. As such, it also provides the advantage that new parameters can be generated that can be used by the design engineer to optimize the technical features of the tongue and groove coupling of the desired effect function. In this case, it is also preferable that each side facing the inside of the slit substantially approaches a plane defined by the surface of the panel-shaped element located on the same side as the first portion of the tongue. With such an orientation, it becomes possible to realize the base of the second portion relatively strong and therefore stable, but the tip portion thereof being thinly held.

As described above, it is preferable that the side portions exhibiting an orientation that deviates from the main direction are substantially inclined as a whole, and more preferably, extend linearly over most of the entire electric field. More specifically, it is preferred that the overall slit is preferably formed with parallel sides, more preferably by an incision and extending at an angle. This allows the realization of such sides and even the entire slit in a simple manner by a saw cutter. Such a sloped slit having a uniform width over its length can therefore combine at least three advantages, namely the easy realization of the slit, the optimization of the first part and the optimization of the second part.

Preferably, the slit extends deeper than the base of the tongue and will have a side biased from the main direction, with the sides deflecting at least toward the portion of the slit that extends deeper than the base. In this way, not only the protruding portions of the tongue are responsible for the behavior of the tongue during bonding, but also the edge portion located further inside the panel-shaped element is also affected in this situation, and additional freedom is obtained for the designer Can be. Furthermore, it is preferable that the sides, sides, which are deflected from the main direction here, each exhibit an orientation that at least deflects at least at a portion of the slit that extends deeper than the base. In combination with this, the distance that the slit extends from the closed surface of the base to the inside of the panel-shaped element or the auxiliary member, respectively, is longer than the maximum distance that the tongue extends to the outside of the closing surface and / Is also preferred.

It is noted that the tongue is preferably located on the end wall edge portion of the panel-shaped element and that the plane associated with the tongue should be understood as the plane on which the panel-shaped element is located.

The panel-shaped elements possibly include a lightweight board having a boundary of different material;

The elements in the form of a panel are constructed as a hollow board or as a board provided with a hollow space having a honeycomb core, for example, possibly with a boundary of another material.

The foregoing materials offer the advantage of being relatively inexpensive. The use of a border is useful when the board itself does not allow it to form profiles therein, for example in the case of a honeycomb panel. In this case, the boundary may be made of, for example, laths in which desired profiles may actually be provided.

It is noted that not only all aspects described above but also the aspects mentioned below can be combined according to the selection, such as all possible combinations between these aspects, so long as the combination of these aspects does not show any contradictory features do. In addition, all secondary features described by the first aspect may optionally be applied in combination with the second, third, fourth, fifth, sixth and seventh aspects, And does not result in a characteristic that

In the slit described above, an elastic element or filler may be provided, for example, to support the elasticity of the movable first portion.

According to an eighth aspect of the present invention, there is provided an assembled element comprising at least three panel-shaped elements interconnected by corner connections, the assembled element comprising at least three panel-shaped elements having engaging portions for providing locking tongues and recessed connections And the corner connections include engagement portions where the first corner connection can be joined together by at least snap insertion movement while the other second corner connection can be joined together only by pivoting Or engagement portions that can be joined together by snap insertion movement; Wherein the snap effect by the second corner connection is more rigid than the snap effect by the first corner connection. By using such different "first" and "second" corner connections, a selection that applies "second" corner connections is obtained, amongst others, On the other hand, on the other hand, other than the snap connection, the "first" corner connections can be used in this case on the position, which allows smooth assembly by snap motion at that position.

Preferably, as well as the second corner connection, the first corner connection allows each tongue and groove to be joined together by pivoting movement.

According to the first choice, the above-mentioned difference is realized by applying a dividing tongue to at least the first corner connecting portion and applying a non-dividing tongue to the second corner connecting portion. In this case the split tongue is more resilient and allows for a smooth snap action.

According to the second selection, both corner connections have a split tongue, the difference being realized at least realized, preferably substantially, by implementing split tongues.

More specifically, the difference in stiffness in the snap effect is at least realized, preferably substantially realized, by the difference in the structure of the slits of the divided tongues. By adopting the shape of the slit, these slits allow smooth selection of the stiffness.

Preferably, this difference is realized by applying any of the following choices or any combination thereof:

The slits of the two corner connections are implemented such that the thinnest material portions between each slit and the closest side wall each exhibit a different thickness;

The slits of the two corner connections are made so that one slit extends deeper than the other slit, i. E. The slits show different depths;

The slits of the two corner connections are arranged to extend at different angles with respect to the elements in the form of a panel.

The eighth aspect is particularly advantageous in that the tongue has corner connections that are of the type having a locking portion on only one side, more preferably a portion of the tongue having the best mobility.

According to a ninth aspect of the present invention, there is provided an assembled element comprising at least two panel-shaped elements, wherein the panel-shaped elements are joined together by a connecting portion providing a locking tongue and a groove connection, Wherein the tongue includes a locking portion on one side and is asymmetric with no locking portion or less significant locking portion on the other side and the tongue and groove connection is such that the tongue is fitted , And that the grooves in cross section are substantially symmetrical, preferably perfectly symmetrical. Here, an advantage that such a groove can be realized as a dead-end groove which can not be realized when realized by a conventional large-sized milling tool is obtained. New application choices are created by using symmetric grooves. Moreover, the same tongues as the asymmetric grooves can be used here, and as a result irrespective of whether the tongs are for the purpose of engaging symmetrical or asymmetric grooves, the same set of milling tools or the like is applied .

According to a tenth aspect, the present invention relates to an assembled element which is in the form of a piece of furniture or a component of a furniture, the assembled element comprising walls forming at least two corner portions in the assembled form of the element And at least one of the corner portions, a corner connection including a film hinge between adjacent walls is used, while at least one of the other corner portions is mechanically Characterized in that a corner connection with locking engagement portions, more preferably a locking tongue and a trough connection, is used. The combination of these two types of corner connections within the assembled element allows to design the whole in a structurally simple manner, but at the same time it can be assembled in an efficient and smooth manner. This tenth aspect is particularly advantageous in embodiments in which the four walls extend vertically to the same plane with the four walls assembled, such as the sidewalls of drawers, in which all the sidewalls are vertically erected on the bottom.

The assembled elements are obtained which can be realized in a particularly smooth way and which can be assembled smoothly, when the walls are mutually adjacent all over and the walls are assembled according to any of the following selections:

- a set of four walls which are connected together by at least film hinges and form three corner connections, on which the fourth corner connection can be achieved, A set of walls;

Two sets of two walls, each set of walls being mutually attached by film hinges, while allowing adjacent sets of free ends to realize locking corner connections between the two sets of walls Two sets of two walls, with coupling portions provided.

It is clear that the tenth aspect is intended to be applied in the case of making a drawer, in particular, in which the four walls form upstanding walls of the drawer.

According to an eleventh aspect, the present invention provides an assembled element, wherein the assembled element is a drawer, the drawer includes at least two side walls, and a front panel for forming a visible front side of the drawer, The front panel being attached to the side walls directly, and the connection with at least one side wall, preferably the connection with both side walls being each implemented by a mechanical locking engagement, To form an upstanding wall of the element. With this design, a structurally simple construction of the drawer is obtained.

According to a preferred embodiment of the eleventh aspect, such an assembled element is further characterized in that the mechanical locking engagement is formed by tongue and groove-shaped profiles comprising locking portions, the locking portions being opposed to movement away from the tongue and groove And more preferably the movement is prevented and the grooves are located on the rear side of the front panel while the tongues are located on the circumference on the front side of the side walls. Thereby, in this case, the front side can be simply pressed down on the side walls. Also, in this case, the front sides only need to have relatively simple groove profiles. This latter is useful when the furniture maker obtains all the components of the drawer except the front panel from another manufacturer. In this case, the furniture maker would not need to realize complex tongue profiles, but only provide the trough profiles on the front panels, which can be done using an inexpensive finger milling cutter.

It is noted that in the case of a drawer, it is not ruled out that the wall has a locally non-linear orientation, for example as in the case of a rear wall having a locally U-shaped recess for forming an open passage for a cable. Also, in certain applications, for example, where the ends that face the rear of the side walls extend beyond the rear wall, it may happen that the corner connections to be targeted are not located on the corner of the drawer. Compartment walls within the drawer are also possible.

According to a twelfth aspect, the present invention provides an assembled element comprising two or more panel-shaped elements, wherein at least two of the panels each comprise a coupling region, Each being provided in the form of a profile extending in the longitudinal direction; The profiles allow the elements of the panel shape to be mechanically locked to form a corner connection and that their planes can be interconnected at an angle; Characterized in that the profiles comprise locking portions as well as tongues and grooves and in the assembled state an adhesive connection, more preferably an adhesive connection, is provided at the position of the corner portion, . The combination of the adhesive connection and the locking engagement results in the advantage that smooth and accurate assembly is possible at first, while a very strong assembled element is achieved after curing of the adhesive.

It is noted that additional adhesive joints or tackifiers by such adhesives may be applied to all other aspects of the present invention.

According to a thirteenth aspect, the present invention provides an assembled element, wherein said assembled element is a piece of furniture using a frame formed by frame panels positioned in the same plane, and wherein one or more, The corner connection is formed in the form of a locking engagement with engagement portions that allow the frame panels to be joined together by snap motion. In this way, the frame can be constructed in a simple manner, for example as a frame of a cabinet door.

Finally, the present invention according to the fourteenth aspect is an assembled element comprising two or more panel-shaped elements, wherein at least two of the panels each comprise a coupling region, Each being provided in the form of a profile extending in the longitudinal direction of the region; The profiles allow the elements of the panel shape to be interlocked in a mechanical locking manner and at an angle; The profiles include tongues and grooves; The assembled element comprises auxiliary means for assisting accurate interassembly of the elements in the form of a panel and the auxiliary means is formed by a three dimensional element in the form of a protrusion cooperable with the corresponding recess, In the direction of the cross section of the tongue, the protrusions preferably extend entirely or through the profile of the tongue in the form of projecting plugs, while the recesses are located in the panel-shaped element comprising the recesses, Is realized in the form of a bore. The particular location of the protrusion relative to the tongue in cross-section provides various advantages as will be apparent from the detailed description.

The auxiliary means are designed to prevent the panel-shaped elements from being engaged in mutually displaced positions and / or to prevent the manufacturer from attempting to join the improper panels together.

Further features of the present invention will become apparent from the following description and appended claims.

In the illustrated embodiment, the engaging portions 13, 14 having profiles in the form of a split tongue 15 cooperating with the recess 16 are used. Such a type of corner connection with such engaging portions using split tongues and grooves is already known from DE 20 2009 008 825 U1.

More specifically, the engaging portions 13, 14 are substantially realized as profiles in the form of tongues 15 and grooves 16, including locking means 17, 18, Opposing to the moving part of the groove 15 and the groove 16, and more preferably preventing its movement. As shown, these locking portions 17, 18 are preferably realized as ribs or edges (eD ges) that form part of the profiles.

As shown, the tongues 15 are each located on each panel-shaped element 2, more preferably on the 2D distal end 19 of FIG. 3, while the recesses 16 are located in a different panel shape And more preferably on side 20 of FIG. 3C, i.e., on one of the large surfaces of the panel-shaped element.

In this case, the joining region 12 is made up of one region of each different panel-shaped element with which the small end edge portion of the element of such panel-shaped edge portion is in contact.

The tongue 15 is comprised of a split tongue and thus has at least two portions 21, 22 and a slit 23 located therebetween. The slit is bordered by side surfaces 24, 25 and bottom surface 26, respectively, which are located on portions 21, 22. The two portions 21, 22 of the illustrated embodiment, hereinafter referred to as first portion 21 and second portion 21, respectively, have different lengths L1, L2.

It is noted that according to variants not shown, the tongue may consist of two or more parts, for example if the part of the extra material must be parallel to the slit. In this case, the previously-targeted slit is divided into two slits, so to speak.

The outer portions 27 and 28 of the portions 21 and 22 shown in the figures cooperate with the side walls 29 and 30 of the recess 16. Furthermore, the groove 16 has a bottom wall 31. As shown, this bottom wall is preferably adapted to different lengths L1 and L2 with respect to the shape, and thus the deeper portion 32 and the less material 34 are retained in the position of the lesser portion 33, And a deep portion 33 is shown. Keeping such material portion 34 is less important for T-shaped connections, but in the case of single-fold corner connections, to maintain a more stable overall in this manner, In order to avoid the risk of lateral breakage of the material to which it is subjected. It is therefore important that the portions 32,33 of the bottom wall 31 remain spaced apart from the farthest distal ends of the portions 21,22 by less than 2 mm It is preferable to follow the overall shape of the tongue 15.

The concave portion 35 is formed in the side wall 29, and as a result, the portion located in front of the concave portion functions as the locking portion 18. [ The locking portions 17, 18 define locking surfaces 36, 37 that engage.

The locking portion 17 is located on the first portion 21 of the tongue.

It is noted that, as shown in the figures, the first part 21 comprises the locking part 17, while the second part 22 is preferably without a locking part, as shown . Such a configuration allows the tongue to be easily pivoted into the groove by the pivoting movement W without creating a large force in the engagement portions, as shown in Fig. However, the present invention does not exclude that the locking portion is also present on the second portion 22, in which case the locking portion is preferably less noticeable than the locking portion 17. Such a less noticeable or thus smaller locking part is shown in figure 4 as a dotted line and is also indicated at 38, where this locking part is realized as a localized protrusion, And can cooperate with the recess 39 shown.

According to the invention, the slit 23 in the cross section of the tongue 15 comprises at least one side, the orientation of which in the cross-section is deflected from the main direction D1 with respect to the tongue, It is preferable to extend at an angle with respect to the main direction D1. In the illustrated embodiment, both sides 24 and 25 are commonly realized in an inclined manner in mutually parallel embodiments, so that the slits 23 in the tongues shown as a whole extend obliquely with respect to the main direction.

The side portion 24 that bounds the first portion 21 of the tongue 15 shown generally as the side portion 24 extends from the distal end to the proximal end of the slit 23, The first portion 21 and / or the first portion 21, in a direction inclined with respect to the main direction D1, so as to approach the surface 40 located on the same side as the portion 21, The portion of the panel-shaped element that is provided extends in an inclined direction such that the slit is entirely thinner toward the proximal end compared to the non-sloped embodiments. As a result, it is apparent that the first portion 21 is elastically displaceable in a relatively smooth manner.

The side portion 25 of the slit 23 forming the boundary of the second portion 22 as a whole is extended obliquely with respect to the main direction D1 so that the side portion extends from the distal end to the proximal end of the slit, Away from the surface 41 located on the same side as the two portions 22, i.e. the side portion 25 extends in a manner inclined in the same direction as the side portion 24. [ In the illustrated embodiment, this contributes to making the base of the first portion 22 stronger and more stable.

Here, the whole is designed such that the first portion 21 and especially its locking portion 17 are resiliently displaceable in a more smooth way than the second portion 22, and the second portion is relatively rigid. The smooth elastic displacement of the locking part 17 is advantageous because the first part 21 is longer than the second part 22 as such, but rather the first part 21 is a part of the panel- That is, a panel-shaped element located between the side 24 of the slit and the surface 40, adjacent to and separated by the thin material portion, separated by the slit 23. The side portion 24 extends obliquely in the direction shown so that the relatively thin material portion is held adjacent to the innermost end portion of the slit and the relatively thin material portion is further located at a relatively long distance from the locking portion Which facilitates smooth elastic bending deformation at the height of this material portion.

The term "slit " should be understood as both the part dividing the tongue and both parts of the deeper extension within the panel shape.

The overall direction of the side portion 24 of the present embodiment and / or the overall or average direction D2 of the slit 23 is deflected from the main direction D1 over the angle indicated by A1. The size of the angle is preferably in the range of 2 to 20 degrees. When the bond has a normal strength, preferably an angle (A1) in the range of 2 to 8 degrees is used, preferably about 4 degrees. It is preferable that an angle A1 of 8 to 20 degrees is used when a low-rigidity coupling is required, in other words, when a coupling that can be smoothly inter-coupled is required.

In the illustrated embodiment, the tongues 15 are located on the small side of each panel-shaped element. Here, the main direction D1 belonging to the tongue should be understood as the direction of the plane in which the panel-shaped element 2d is located.

As shown, the tongue 15 is positioned eccentrically with respect to the center plane M of the panel-shaped element in which the tongue is located, wherein the assembled element 1 is at least partly tangent to the tongue At the side, an inner corner between the panel-shaped elements is formed. More specifically, the tongue as a whole is positioned outside the center of the panel-shaped element 1 in such a manner that the tongue is positioned closer to the side positioned in contact with the inner corner 22 than the opposite side, do.

The tongue 15 is fitted in the recess 16 by a pivoting movement W as shown in Figure 5 wherein the pivoting panel-shaped element (in this case 2B) . This turning motion W occurs along the side of the inner corner portion of the assembled element shown. Disassembly of both panel-shaped elements occurs by pivoting in opposite directions, or by tapping or pulling the panel-shaped elements from each other in a direction parallel to the tongue.

It is noted that the panel-shaped elements can also be joined together by a snap motion by displacing panel-shaped elements by reciprocal translational motion, as shown in Fig.

Here, the tongue 15 is fitted in the groove 16 by a snap motion, such as pressing each panel-shaped element with the tongue 15 toward the groove 16 in its plane. In the embodiment shown, this fit is achieved because the locking portion 17 can perform a lateral elastic movement in combination with the slightest elastic compression possible in the material of the two locking portions 17,18, The locking portion 17 can engage behind the locking portion 18, all of which are independent of whether or not they are combined with some additional compression in the material of the tongue and groove.

The slits 23 preferably have a width equal to or greater than the maximum lateral displacement performed by the locking element 17 with respect to the panel-shaped elements to which the locking element belongs during mutual snap engagement.

Moreover, the entrance of the groove 16 has a small insertion angle A2, which is preferably less than 40 degrees, more preferably about 30 degrees.

As a whole, the tongue is conically shaped with a conical side formed by the outer portion of the second portion 22 and the outer portion of the locking portion of the first portion 21.

The embodiments shown in the figures are designed so that the tongue 15 and the recess 16 can be coupled together in two ways, not only by pivoting movement but also by snap movement through translational motion, It is clear that the tongue 15 and the groove 16 constituted. This is evident from Figs. 4 and 5, which illustrate two coupling techniques for tongues and grooves, each of the same type.

As shown, it is preferred that the tongue 15 and the recess 16 are realized integrally within the panel-shaped elements by, for example, a milling process. Here, the tongue 15 is located on the small side of each panel-shaped element, while the groove is provided on the side of each panel-shaped element.

As shown in the drawings, it is preferable that the panel-shaped elements are formed of a cover board which is preferably provided with coating layers 42 and 43 on both sides, respectively. This is preferably related to melamine-coated boards, and thus boards with laminated coatings. In particular, it is assumed that the laminated layer, whether or not combined with other layers, is provided with a resin and at least consists of a decorative layer pressed on the board. Examples are HPL (High Pressure Laminate) or DPL (direct Pressure Laminate). Also, films, lacquer layers, etc., or any other type of coating may be applied.

The basic board itself is preferably made of MDF, HDF or particle board. Particle boards are often not as stable as MDF or HDF and are easier to break up, but particle boards are lighter and this lightweight is chosen for aesthetic reasons to work with relatively thick walls, for example, 18 mm thick or thicker , The particle board is preferable for furniture. The present invention contributes that such profiles may be implemented in the material of the particle board in an efficient manner.

On the edge portion, the panel-shaped elements may have a finishing tape 44, such as, for example, a laminated tape or a composite material finish tape (e.g., ABS tape). Figures 1 and 7 also show that the ends of the tongues and grooves extend such that the finishing tape extends beyond the distal ends of the groove 16, i. E., In a manner similar to that described in DE 20 2009 008 825 U1, By providing a covering, it can be hidden by such a finishing tape. Such tape coatings are carried out by the manufacturer.

According to the second aspect of the invention, in the illustrated embodiment, in combination with a slit 23 extending at least deeper than the projecting portions of the tongue, i. E. To a position exceeding the closing surface 47, (45, 46) is applied. Here, the first contact point is defined as the contact which is located closest to the closing surface 47 between the groove and the first part 21 of the tongue 15, while the second contact point 46 is defined as the contact between the groove and the tongue 15 Is defined as the contact most distant from the closing surface 47 between the second portions 22. This particularity consists in that the first contact point 45 is located closer to the closing face 47 than the second contact point 46. On the other hand, by this a better distribution of forces is obtained for the force at the coupling. In addition, one panel-shaped element is arranged with the groove 16 facing upward, while the other panel-shaped elements are arranged in a downwardly directed orientation of the tongue 15, At the intermediate positions, it is possible to obtain the second panel that is not tilted very quickly even if it is left standing.

It is noted that in the engaged condition, the closing surface 47 is generally made of a surface that coincides with the panel surface 40 where the end of the groove 16 is located.

As shown, on the entrance of the groove 16 of the side which is the starting point from which the tongue pivots into the groove, it is preferred that an angular cutout 48 can be realized on the edge 49, Allowing for seamless turning-in.

The embodiments shown in the drawings also apply to the third independent aspect of the present invention. The length of the first portion 21 and the second portion 22 of the tongue 15 is denoted by L1 and L2 respectively while the center of the closing surface 37 is within the surface of each board The distance to be located is indicated by L3. According to a third aspect, the tongue 15 has a slit, and the locking portion 17 is on the outer side of the first portion 21, while there is a less significant locking portion on the outer side of the second portion , Or even that there is no locking portion. The second portion 22 of the tongue 15 protrudes from the closing surface 47 by a length L2 which is greater than the length L2 of the first portion 21 of the tongue 15, Lt; RTI ID = 0.0 > L1 < / RTI > By emphasizing this ratio, the tongue can be smoothly pivoted on the one hand, while on the other hand, such engagement and locking can be realized in the first part as the relative second part is not excessively disturbed . Also in this case proportionally less deeply positioned portions of the bottom wall of the groove can be implemented with a shallower depth, which results in a very strong wall of the groove.

The illustrated embodiment also has the advantage that the slit 23 extends to a depth extending beyond the closing surface 47 and moreover the second portion 22 of the tongue 15 is in contact with the locking surfaces 36, 37) protrude by a length L2 from the closing surface 47 which is less than 1.5 times the average distance L3 spaced from the closing surface, according to a fourth independent aspect of the present invention. Thereby, the distance that the second portion 22 protrudes is obtained that is limited to the position where the first portion 21 engages. By this limitation, it is excluded that the excessively projecting portion 22 experiences as an inconvenience during the coupling. In order to ensure stable bonding, in this case, the length L2 is preferably larger than L3.

Particularly in the depicted embodiment a portion of the first portion 21 extending between the closing surface 47 and the locking surfaces 36 and 37 has an average thickness greater than the average thickness T2 of the second portion 22 As the features are also shown, this embodiment also forms an embodiment of the fifth aspect of the present invention. By this projection starting from the same overall thickness of the tongue 15, it is obtained that the first part 21 becomes stronger and more stable, which means that this first part has a locking part, It is clear that it is important to consider the fact that you are under load. It is particularly apparent that the fifth embodiment is particularly advantageous in embodiments in which the tongue is eccentrically mounted and the slits extend deeper into the elements in the form of a panel than the base of the tongue, as shown. Thus, in this case, the first part 21 in this case is extended by the portion of the notched material of the panel-shaped elements with which this first part 21 contacts, so that even if the first part is so stable It is possible to produce a large amount of elasticity, but a considerable elasticity can still be generated.

T1 is preferably the average thickness of the portion extending over the distance L1 and / or its thickness measured in the middle of the length L, while T2 is preferably the average thickness of the second portion 22 and / It is noted that the thickness is measured. The possibilities can be applied according to the criteria that the manufacturer wants to use.

According to the sixth aspect, the depth L4, in other words the distance L4 from which the slit 23 extends from the closing surface 47 toward the interior of the panel-shaped element 2, is greater than the maximum distance Ll extending from the closing surface long. It is clear that this is advantageous for the mobility of the first part 21. Moreover, the deformation caused by this can be further transmitted to the rear, so that the tip of the first portion 21 is subjected to a smaller load to deformation at the position of the locking portion.

According to the seventh aspect mentioned at the beginning, the tongue and groove have a configuration in which the maximum of the force must be overcome at the time of turning relative to the mutual toward the end of the swiveling motion, and as a result, As indicated by the contact points 50, 51 in Fig. 6, the force must be overcome here, as in the case of the pivotal movement W here, the contact is held adjacent the edge portion 49. [ In this way, the holding means or the blocking means are integrated into the coupling portion itself, in which case the holding means or the blocking means are provided with a tongue and a groove, and thus a deceleration which counteracts the turning of the panel- Effect is obtained at least. In order to prevent the one panel-shaped elements provided in the temporary upright position in this case at particular intermediate positions during the assembly of the furniture, as described above, to be folded against one another, useful.

As shown in Fig. 6, this provides a portion 52 that theoretically overlaps the portion 53 on the groove during pivoting in the direction of mutual engagement or disengagement, in the tongue of the side where the locking portion does not exist, As a result of which the force of a dead point, more preferably the strain, can be overcome.

Also according to the alternative shown in FIG. 6, the tongue and groove at the height of the locking portions may include portions provided that the deformation force is overcome at the dead point by the theoretical overlapping portion 36A during the turn.

It is clear that both choices may or may not be combined.

Also, the profiles can be executed so that tension is maintained, particularly in the so-called pretension, in the combined state.

It is clear that the coupling can be applied on various locations on assembled elements, such as furniture, in order to realize a corner connection of a typical corner connection, a T-connection, or even a cross connection. However, this does not mean that all corner connections of such assembled element 1 should be so realized.

The invention is particularly applicable to tongue-like external elements such as wedges or the like which are driven into a tongue slit, for example, as known from US 7,654,055, while the tongue provides such a coupling effect, The present invention is directed to embodiments that are maintained in a non-existent state. Indeed, as such, the tongue may include elements that are attached to the tongue in a fixed state and that can support the tensions provided by the tongue, such as, for example, a mass provided in an elastic strip or a slit in the tongue have.

Moreover, if desired, the present invention is not limited to corner connections that extend in horizontal directions in an assembled state of use, but may also be applied to corner connections extending in other directions, e.g., vertical . An embodiment of the vertically extending connection, meaning that the coupling area extends in the vertical direction, is similar to that shown in Figs. 54 and 55 of DE 20 2009 008 825 U1 described above, for example, Are connected to the rear wall by the corner connection portion of the present invention.

Herein, the term "coupling zone ", as applied above, should be understood as part of the profile, e. G., A groove-like profile or a panel-shaped element in which the tongue profile extends. Here, this is not only an area clearly separated from the edge portion of the panel-shaped element, but also an edge portion of the panel-shaped element, for example, for the purpose of forming a T- Or may be related to an area located directly adjacent to the edge.

Also, the term "assembled element" in accordance with the present invention should be understood as an element in the state of "assembled" This means that in this case also the flat pack member of the furniture that has not yet been assembled and still packed, which exhibits one or more of the features of the present invention, for example in the assembled state, should also be considered as an already assembled element.

When the term "intermediate piece" is used, this is the element applied on the corner between the two panel-shaped elements, in which case each engagement is achieved by at least one of the panel- And intermediate members. An embodiment of the use of the intermediate member is shown in WO 2010/070605, for example, in Fig.

When it is mentioned that the side of the slit has a deflected orientation, this actually means an intrinsic part of the side of the slit, and thus does not mean, for example, a curved part at the end or end of the slit, an inclined part or the like.

It is also noted that the "locking surface" may possibly be understood as a line contact.

The side extending deflecting from the main direction D1 can also be understood as a side having a step-like orientation. Further, for example, the side portions 24 can extend substantially parallel to the direction D1 to bend toward the surface 40 only adjacent to the deepest end of the slit.

It is apparent that the embodiments according to the second to seventh aspects do not necessarily have to have the tongue 15 with the slit 23 extending obliquely. In such a case, for example, as indicated by the one-dot chain line 23A in FIG. 3, the slits may extend parallel to, for example, the respective main directions D1.

The first choice of the eighth embodiment mentioned at the beginning of Figs. 8 and 9 is shown. The assembled element 1 thus shown comprises at least three, in this case three or more panel-shaped elements 2, which are joined together by corner connections 54,55 and 56,57 . Wherein the assembled element includes corner connections having engagement portions, wherein the engagement portions provide a locking tongue and a groove connection. The "first" corner connections 54, 55 include engagement portions that can be interconnected at least by snap-insert-movement, while such "second" corner connections 56, 57 That is to say the corner connections 54 and 55 on the one hand and the corner connections 56 and 57 on the other in that they comprise the coupling parts 56 and 57 which can be mutually bonded only by pivoting motion, , 57) are different from each other. It is noted here that not only the "second" corner connections 56, 57 but also the "first" corner connections 54, 55 allow the respective tongues and grooves to be joined together by pivotal motion. In Figure 9 the difference is that by applying a split tongue 15 to each of the first corner connections 54 and 55 and applying a full tongue 15 to each of the second corner connections 56 and 57 .

10, wherein both corner connections, i. E. One corner connections 54,55 and the other corner connections 56,57, have a split tongue and the difference described above is at least Preferably by substantially differently implementing these split tongues 15, and more preferably by the difference in the structure of the slits 23A, 23B of the split tongues 15.

In the embodiment of Figure 10, the difference is realized by a combination of the following features:

23B of the two different corner connections so that the thinnest material portions between the respective slit and the closest side wall always show different thicknesses TA, TB, in this case TA is less than TB, , So that the upper slit on the one hand and the lower slit on the other hand are implemented;

One of the two different corner joints 23 is arranged so that one slit 23A extends deeper than the other slit 23B, in other words, it has a different depth DA, DB, The slits 23A, 23B, and hence the upper slit and the lower slit on the other side are implemented;

The slits 23A and 23B of the two different corner connections, and thus the upper slits and the upper slits, of the two different corner connections, so that the slits 23A and 23B extend at different angles XA and XB with respect to the panel- The slit on the lower side is implemented.

As a result, it is apparent that the uppermost corner joints of Fig. 10 can be mutually snap-engaged with lower stiffness compared to the lower ones.

In the embodiments of Figs. 9 and 10, the split tongues of both corner connections are of the type having the locking portion 17 on only one side of the tongue, more preferably on the portion having the best mobility of the tongue.

8, 9 and 10 show that at least one of the panel-shaped elements is in this case the upper wall 6, by means of the snap insertion movement by means of at least two corner connections 54,55, Also shown is a feature that acts as a closing member 58 that is coupled to the elements, wherein these two corner connections are implemented as "first" corner connections, while a number of other corner connections 56, 57), in which case the remaining lowermost corner connections are realized as "second" corner connections. In the illustrated embodiment, this is evident by this, which allows the lower corner connections to be particularly robust, while the upper corner connections provide the advantage of being able to perform a smooth snap action.

It is noted that the above is also applied to the T-shaped corner connection portion.

11 to 13 show a ninth aspect of the present invention. As described in the introduction, a substantially symmetrical recess 56 is used, substantially and preferably, when viewed in cross section here. As shown schematically in FIG. 12, this groove may be formed by a finger milling cutter 60.

The advantage of this technique is that the grooves 59 can not be formed continuously and can be formed in at least one end 61 of the material of each panel-shaped element, for example in office furniture described herein below It can be applied for applications that need to have an end.

The illustrated office furniture has a purpose for forming a connection between the side panels 62 and 63 to maintain the side panels 62 and 63, the top panel 64, and the side panels 62 and 63 in parallel And an intermediate portion 65 of the second housing 60. FIG. All components of this furniture are assembled entirely by locking profiles only. During assembly, the side panels 62, 63 and the intermediate portion 65 are joined together by pivoting movement, wherein the tongues 15 located on the ends of the intermediate portion 65 are joined to the side panels 62, 63 into a symmetrical recess 59 located on the medial side. The upper plate 64 is pressed downward on the upper edges of the side panels 62 and 63 in a state where the groove 16 is positioned on the upper side of the tongue 15, .

The ninth aspect is also useful for drawers in which one or more upstanding walls are assembled together by locking profiles. It is recommended here that the grooves 59 are not actually formed continuously in certain applications, in which case symmetrical grooves 59 may be applied and the ends 61 of these grooves 59 may be located at a desired position have. A number of embodiments of this are described below.

Also, in applications where such symmetrical grooves are formed substantially continuously, this can be useful. Regardless of whether symmetrical grooves are formed continuously or discontinuously, the advantage of such symmetrical grooves is that at least the geometry and even the entire grooves are realized with a single milling cycle, which saves expense.

Another advantage is that the locking should occur on the left side of the groove or should occur on the right side, regardless of whether the groove is always the same. As different grooves are unnecessary, in certain applications, the operations required to realize the locking grooves can be considerably simplified.

It is noted that the tokens applied to the eighth or ninth aspects may always optionally include one or more features described herein with respect to the split tongues when these tokens are split tongues.

Figs. 15 to 19 show respective specific parts of the assembled element 1 in the form of a drawer, wherein the assembled element satisfies the tenth aspect of the present invention. Here, the assembled element 1 comprises panel-shaped elements 2E, 2F, 2G, 2H, and the panel-shaped elements 2E, 2F, 2G, In the combined form of the elements, these walls form four corners, and the panel-shaped elements serve as the corner connections < RTI ID = 0.0 > (70, 71, 72, 73). In the two rear corner portions, the corner connecting portions 70 and 71 each including the film hinge 74 are always used, while at the positions of the corners of the front, the mechanical locking engaging portions 13 and 14, Corner connection portions 72 and 73 having a locking tongue and a groove connecting portion are used.

As can be seen in the enlarged view of Figure 17, it is preferred that such a film hinge be formed, with a continuous coating 75 being provided on adjacent panel-shaped elements 2F, 2g, In other respects, the panel-shaped elements are separated from each other by a suitable recess 76. In order to realize this, it is preferable to start from the board provided with the cover 75, and in this case, the necessary recesses 76 are provided without cutting the cover. This does not exclude that such a film hinge 74 is formed, for example, in other ways, for example by a folDAble adhesive connection of a strip of a heat-meltable adhesive. It is also not excluded to form coupling portions such as to be interdigitated in the side portions 77,78 of the one or more recesses 76 to be mutually engaged or to be joined in other portions, As soon as the elements are turned toward each other along the respective film hinges, they cooperate with each other.

The locking engagement portions 13,14 may be of any kind but the locking engagement portions 13,14 may be formed in the tongue 15 having the locking portions 17,18 and in the recess 16 . More specifically, these are preferably realized as described above. In this case, whether or not the slit 23 is used in the tongue is irrelevant, and when the slit is applied, such a slit does not necessarily have to be inclined.

Thus, all components can be distributed in a flat state. To assemble the drawer, the panel-shaped elements 2E, 2G are in the state of Fig. Here, the bottom 79 can be received between the walls 66, 67, 68 in the grooves provided for this purpose. The front wall 69 is then snap-engaged downwardly using troughs 14 on the tongue 13. On the rear side of the front wall 69, a recess 80 is preferably provided, as shown in FIG. 18, which defines a seat for the edge of the front of the bottom.

In the illustrated embodiment, the front wall 69 forms a visible front panel, whereby this embodiment forms the application of the eleventh aspect. However, according to a variant, it is clear that the wall 69 can serve as a simple front wall, while in this case an additional separate front panel is provided in front of it.

20 and 21, a modification of the tenth embodiment is shown wherein all four walls 66, 67, 68, 69 are interconnected by film hinges, in this case the corner connections 70, 71 and 73 are formed by the film hinges while the corner connection 72 is achieved by the locking engagement portions 13 and 14 located adjacent to the free ends of the walls 69 and 66. An additional front panel can be provided in contact with the front wall 69, as shown in dashed lines.

22 shows another embodiment, wherein the front wall 69 realized as the front panel is directly connected to the side panels by at least one locking engagement, in this case two locking connections, This embodiment satisfies the eleventh aspect of the present invention.

Figure 23 shows a twelfth aspect of the present invention. Its singularity is realized in that the corner connection is realized as the locking engagement portions 13,14, which in this case is combined with the adhesive connection which is the adhesive connection by the adhesive 84. [ In the illustrated embodiment, the adhesive 84 has two functions. The first function is to realize an additional connection between the two panel-shaped elements since the adhesive is provided between the tongue and the groove. The second function is to mutually fix the two parts 21, 22 by curing the adhesive 84, and in particular by the presence of the adhesive in the slit 23, the post-cured parts 21, It becomes difficult to move toward the center of the body, resulting in a stronger coupling. According to variations not shown, it is clear that the adhesive can also be applied to a position that can only meet the first function or the second function.

Figures 24 to 28 relate to an embodiment of the thirteenth aspect of the invention, or at least its essential components. 24 shows a fixed panel or cabinet of a cabinet having a frame 85 consisting of a panel of assembled panels, for example a panel of cabinets, for example frame panels 86, 87, 88, As shown in FIG. Within the frame 85 is a central panel 90 which is seated in a rebate 91 such as the grooves on the inside of the frame panels 86, 87, 88 and 89. The difference is that the frame panels may be coupled to each other by the locking engagement portion 92, as can be seen in Fig. Also, as can be seen in FIG. 28, for example, the above-described locking engagement portions 13 and 14 can be used, but other types of engagement portions are not excluded. It is in fact important that it relates to the engagement parts which can be pressed against each other by the snap movement 93. [

As shown schematically in Figures 24-27, it is preferred that the tongue 15 and the recesses 16 be present locally at each of the edges to be engaged, i. E., Not over their entire length So that the tongue 15 and the grooves 16 are not visible at the outer edge of the frame.

29 and 30 show a fourteenth aspect of the present invention. At this corner connection, profiles 94, 95 are used, with locking engagement portions including tongue 15 and recess 16; Wherein the entirety comprises auxiliary means for assisting correct interassembly of the elements in the form of a panel, the auxiliary means being formed by a three-dimensional shaped element in the form of a projection 96 cooperable with a corresponding recess 97, Being; The projections 96 viewed in the cross-sectional direction on each profile extend in the form of plugs which project completely or mostly through the tongue profile 94, preferably in the form of projecting plugs, while the recesses 97 extend along the groove 16 And is preferably located in the form of a bore.

29, the protrusion 96 has a diameter slightly larger than the thickness of the tongue, and when the protrusion is positioned opposite to the recess 97, the panel-shaped elements can be joined together entirely by this. 30, the protrusions extend in a more distally direction than the tongues 15, and consequently, the elements in the form of a panel also can be joined together when the protrusions are positioned against the recesses 97 There is only. The illustrated positions of the protrusion 96 for the tongue 15, where the protrusions 96 are completely or substantially perfectly positioned at the position of the tongue, are particularly thicker for the panels to engage such protrusions Lt; RTI ID = 0.0 > a < / RTI > Conversely, this also means that this type of integration is particularly suitable to be applied in thin panel shaped elements, for example less than 15 mm.

29 and 30, both of these protrusions 96 and associated recesses 97 have the same or substantially the same diameter. In this case, the elements of this interrelated panel shape may be joined together only by translational motion. This does not exclude that the fourteenth aspect may be applied to panel-shaped elements that can be joined together by other motions, such as pivoting motion. For example, in FIGS. 29 and 30, each protrusion 97 may be tilted in the recess 97 during the pivotal movement of the tongue into the groove, to allow the panel- the recesses 97 may be formed to have a slightly wider transverse width of the grooves compared to each of the associated projections 96. In this way,

The term " mechanical locking engagement portions "as used herein means that locking occurs in the assembled state, so that the elements in the form of a panel can not be separated from one another without overcoming certain forces in their normal assembled state It should be understood that the term "

Accordingly, all of the above-described features of the present invention, as well as the features of the profiles shown in the drawings, and therefore the features of the tongue profile and / or concave profile, are not intended to be inconsistent with the central meaning of such independent features May each be applied alone or in any possible combination with any of the fourteenth independent aspects. Accordingly, some of these features that can be combined according to the selection are, for example, as follows:

- the tongue comprises two parts (21, 22), whether or not separated by the slit (23), the part of one of these parts (21, 22) being shorter than the other part;

The tongue has a slit (23);

The shape of the tongue and / or groove meets any of the dimensional proportions of the dimensional proportions described herein;

The tongue includes a locking portion 17 only on one side;

- the tongue can be turned into a groove;
