Description

Frame for drawer

Technical Field

The invention relates to a frame for a drawer, comprising an outer housing and an inner housing, wherein the outer housing is displaceably guided relative to the inner housing, and wherein a cavity is formed between the outer housing and the inner housing, which cavity has one or more functional devices.

Disclosure of Invention

It is an object of the invention to further develop the generic framework in a functionally advantageous manner.

The invention solves this object by the subject matter of claim 1. There is also formed a drawer for furniture, the drawer having one or more frames according to any one of the claims.

It is then proposed that the outer housing in a first position relative to the inner housing prevents access to at least one of the functional device or functional devices and accordingly covers said functional device, wherein the outer housing or the inner housing has an opening via which at least one of the at least one functional device or functional devices or also several or all of the functional devices can be accessed in a second position which is displaceable relative to the first position in the longitudinal direction of the frame (i.e. in the main direction of extension of the frame, in particular parallel to the pull-out direction of the associated drawer). For the purposes of this description, an opening can be designed in particular as a window or hole in a flat material made in particular of sheet metal or plastic, or also as an edge depression in a flat material preferably used to make the housing. In this way, the outer housing is advantageously and simply fixed relative to the inner housing, wherein this connection can be easily released in order to be able to access one or more functional devices. In this way, the frame is functionally further developed in that a good locking of the housing and a good access to one or at least one of the several functional devices is achieved.

Preferably, one or more latching elements may be arranged on the outer or inner housing in the cavity, which engage the opening of the inner or outer housing, respectively, in the first or second position, preferably completely or partially closing the respective opening. In this way, one or more latching elements are advantageously arranged within the frame, where they are not visible to the user.

It may be provided that the latch and thus the first or second position can also be easily released outside the frame by releasing the latching position of the respective latch element from outside the frame with a tool or by hand, so that a displacement of the outer housing relative to the inner housing is possible.

Preferably, the latch element is fixed to the inner housing and the opening is provided in the outer housing. This results in a particularly advantageous functionality and overall aesthetic appearance of the frame.

In a preferred embodiment variant of the invention, the functional means comprise one or more locking means, one or more adjustment means, one or more guide elements. The basic function carriers of the drawers can thus advantageously be arranged in the interior of the frame, where they are not visible to the user. In any case, in the sliding position of the outer housing relative to the inner housing, one of these functional means can be easily and safely actuated, preferably with a tool, via the opening, wherein the latching element is also released from the latching position.

In a further preferred embodiment variant of the invention, the outer wall section of the outer shell has an upper edge which is bent at least 90 ° and/or optionally further in particular 180 ° towards the inner shell, or is formed as a further outer shell separate from the outer wall section of the outer shell. Thus, the outer housing advantageously simply reinforces and/or thereby receives the more visually appealing optics and upper covering.

In another preferred embodiment variant of the invention, leg-shaped guide tabs bent downwards by 90 ° are formed on the upper edge of the outer shell of the frame. This makes it easy to construct the slide guide in combination with the guide element mountable on the inner housing.

In a further preferred embodiment variant of the invention, the upper edge of the outer wall section of the outer shell of the frame may have an opening. The opening is preferably used for easy access to the adjustment device with a tool, such as a screwdriver. The adjustment means may be used, for example, to adjust the inclination of a wall (e.g., a front or rear panel of the respective frame) relative to the pull-out guide. For this purpose, in the displacement position corresponding to the second position of the outer housing, the tool engages in the torque driver geometry of the adjustment device, in particular a spindle arranged vertically to the drawer bottom, so that an adjustment can be easily and advantageously made by turning the screwdriver.

In a further preferred embodiment variant of the invention, the inner shell can form an inner wall section with an upper edge. In this way, the inner shell is advantageously simply reinforced.

In a further preferred embodiment variant of the invention, the upper edge of the inner wall section can be bent outwards or towards the outer housing, so that it forms a support leg in the manner of a cross beam. In this way, the assembly stage is simply formed in the cavity of the frame.

In a further preferred embodiment variant of the invention, the support leg can be used for attaching one or more latching elements. Thus, one or more latch elements are advantageously protected and visually concealed.

In a further preferred embodiment variant of the invention, the latching element can be designed according to the principle of a clasp. In combination with the opening, this results in a structurally simple latching connection which can be assembled and disassembled quickly and easily.

In a further preferred embodiment variant of the invention, the clasp can be designed as a one-sided lever. This is a simple and proven design of the clasp.

In a further preferred embodiment variant of the invention, the latching element can have a base section. The base section is designed as a sliding tray, so that the base section has a trough-like receptacle for supporting the legs. The trough-like receptacle is formed by an upper leg and a lower leg. This provides a simple and thus advantageous pre-assembly option for the latch element by simply pushing the sliding bracket onto the support leg.

In another preferred embodiment variant of the invention, the upper leg may have a recess and the lower leg may have several angled cut-outs, each angled cut-out having an exposed lobe. Further, the lower leg may have a latch hook corresponding to the recess. The latching hook may also have a further latching recess corresponding to the latching hook when the latching element is mounted. This provides a simple and therefore advantageous method of securing the latch element by simply latching the latch element onto the support leg.

In a further preferred embodiment variant of the invention, the upper leg adjoins the latching section. The latching section has an upturned edge on the narrow side of the base section and is designed as a one-sided lever. This results in an advantageously simple construction of the latching section.

In a further preferred embodiment variant of the invention, the latching section can have an upturned edge on the long side of the base section. The latching section is designed like a bridge. This results in an advantageous rigid design of the latching section and thus in an advantageous safety latch.

In a further preferred embodiment variant of the invention, the one-sided lever can be integrally connected to the block-shaped central part. In this way, reinforcement of the latching element is simply formed.

In a further preferred embodiment variant of the invention, the latching section can have a latching nose for engaging the opening. In this way, the outer shell is advantageously and simply fixed relative to the inner shell and/or the opening is securely closed.

In a further preferred embodiment variant of the invention, the latching noses can be pressed or chamfered at an angle on at least two of their edges. This makes it easier to attach the latch nose to the opening.

In a further preferred embodiment variant of the invention, the latching noses can be rounded off at least on two of their edges with a certain radius. This makes it easier to attach the latch nose to the opening.

In a further preferred embodiment variant of the invention, the latching section can have a chamfer. In this way, the stroke limitation of the latching section is simply formed.

In a further preferred embodiment variant of the invention, the latching element is produced as a stamped and bent part from a sheet-or strip-shaped blank. This results in a light weight latch element which is easy and inexpensive to manufacture.

In a further preferred embodiment variant of the invention, the latching element can be produced in one piece from plastic by means of an injection molding process. This results in a light weight latch element which is easy and inexpensive to manufacture.

In a further preferred embodiment variant of the invention, the latching element can have a guide groove. The guide channel is formed by a wall section and a base section. The guide groove may be engaged in an assembled state of the latch element with the frame of the guide tab of the outer housing. In this way, the further guide element is simply formed, so that the sliding guide is advantageously further reinforced.

The invention also advantageously forms a drawer having a rear panel, a drawer bottom, a front panel and one or more frames according to any one of the claims.

Further advantageous features of the invention can be found in the dependent claims.

Detailed Description

Fig. 1 shows a piece of furniture designed as a cabinet-type furniture 2. The cabinet furniture 2 has a main body 3. As an example, three drawers 4, 5 are inserted into the furniture body 3. The drawers 4, 5 can be guided slidably in the furniture body 3, so that each of the drawers 4, 5 can be pulled out of the furniture body 3 into an open position and pushed back from this position into a closed position, respectively.

The drawer 5 shown in fig. 2a and 2b has a front panel 6a, which is shown here as a relatively high front panel 6a by way of example. The drawer 5 also has two side frames (hereinafter also referred to as frames 1) and a rear panel 7.

In fig. 2b, it can be seen that the frames 1 are preferably configured with two housings each. The frame 1 has an elongated outer shell in the form of a shell having an outer shell 8 and an inner shell 9.

The outer housing 8 is held by and movable relative to the inner housing 9. Preferably, the outer housing 8 is held to the inner housing 9 and can be moved to a limited extent. The inner housings 9 each enclose a narrow cavity together with the outer housing 8.

The terms inner housing 9 and outer housing 8 do not mean that they have to be constructed in one piece. The inner housing 9 and the outer housing 8 may in turn be composed of or formed from several elements, such as sheet metal strips, so that these elements together form the inner housing 8 and the outer housing 9.

The drawer 5 also has a drawer bottom 10. Preferably, but not necessarily, the outer housing 8 and the inner housing 9 are made of sheet metal, in particular steel. However, they may also be made of other materials. Preferably, the inner housing 9 and the outer housing 8 are each made in one or more pieces of one or more sheets, in particular of steel sheet, which have been bent in sections to form a certain shape and possibly have been formed with depressions or the like thereon by stamping, cutting or the like.

It is further preferred that the outer housing 8 and the inner housing 9 form a frame having a relatively small (i.e. "narrow") width, preferably less than 15mm, in particular narrower than 12 mm. The invention is advantageously particularly suitable for such narrow frames 1.

Several functional devices may be arranged on or in each of the frames 1. The functional device is arranged substantially in the cavity between the outer housing 8 and the inner housing 9. These functional means may comprise, for example, one or more locking devices 24, one or more adjustment devices 25, one or more guide elements 109 and one or more latching elements 100 (see, for example, fig. 5a, 5 b).

In order to provide access to the functional elements, which are arranged wholly or partly in the intermediate space between the inner housing 9 and the outer housing 8, in particular to the adjustment means 25, it is advantageous if the inner housing 9 is movable, preferably with limited movement, relative to the outer housing 8 (see, for illustration, for example fig. 4a and 4 b).

In fig. 4a, it can be seen that the outer housing 8 can be designed in one piece. In addition, the outer shell 8 has an outer wall section 11 which substantially or completely forms the visible outer wall of the frame 1. In the direction of the rear panel 7, the inner shell 9 is shorter than the outer shell 8 by its width B.

Preferably, the upper edge 12 of the outer wall section 11 can be first bent 90 ° towards the inner housing 9 and/or further bent 180 ° (thus facing away from the inner housing 9), or it can be designed as a further separate outer housing (8'), for example in the shape of a strip. Further, a leg-shaped guide tab 13 bent downward by 90 ° (see fig. 6) may be formed on the upper edge 12 of the outer case (8, 8').

Fig. 3a, 3b, 4a, 4b show here that the upper edge 12 of the outer wall section 11 of the respective frame 1 has an opening 14. The opening is designed here as a quadrangular, in particular square, opening 14. Alternatively, the opening 14 may also have a different geometry, in particular it may also have a circular geometry, i.e. be designed as a "hole". Furthermore, the opening 14 may also be attached to the outer housing 8 at a different location. For example, the position of the opening 14 in the outer wall section 11, i.e. at a position perpendicular to the position at the upper edge 12 of the outer wall section 11, is conceivable.

The opening 14 is used for operating the adjustment means 25 with a tool, such as a screwdriver. The adjusting device 25 is used, for example, to set the inclination of the drawer relative to the pull-out guide. For this purpose, in the second position of the outer housing 8, the tool engages in the torque driver geometry of the adjustment device 25, so that an adjustment can be easily and advantageously made by turning the screwdriver (see fig. 4b for this reason). In the first position of the outer housing 8 (see fig. 3a and 3 b), the opening 14 is penetrated by the latching nose 101 of the latching element 100.

The upper edge 12 here also forms a strip section 15 which is arranged at an angle to the outer wall section 11 and which closes the outer shell 8 at the top. For this purpose, the cover section 15 is preferably bent by 90 ° relative to the outer wall section 11, or is designed as a separate strip of the multi-part outer shell 8, 8'.

The upper edge 16 of the inner wall section 17 (see fig. 5a, 5b, 6) is bent outwards or towards the outer housing 8 such that it forms a support leg 18 in the manner of a cross beam. This forms a receiving channel 19 between the support legs 18 and the inner and

outer shells

8, 9 towards the upper edge region.

The support leg 18 serves here for attaching several guide elements 21, which are arranged in the receiving channel 19, where the guide elements are advantageously protected and optically concealed. The outer housing 8 or the guide tab 13 slides over the guide element, thereby forming a sliding guide with the outer housing 8 or the guide tab 13 (see fig. 5a, 5b, 6). This is advantageous but not mandatory within the scope of the invention.

Preferably, several of the guide elements 21 are spaced in rows on the support legs 18 of the inner housing 9. The support legs 18 and the adjacent wall areas of the inner shell 9 form two of the walls of the receiving channel 19. The other two walls of this receiving channel 19 form the outer housing 8. Thus, the receiving channel 19 is always closed. This means that the upper guide element 21 is not visible from the outside when mounted on the drawer.

The guide element 21 can be fixed in a fixed manner in the receiving channel 19, for example with screws or rivets and/or latching means or the like. Due to its simplicity and uncomplicated fastening is preferably performed with at least one latching hook 109 or several latching hooks engaging in latching recesses 110 (see fig. 6) of the support legs 18.

In fig. 5a, the outer housing 8 of the frame 1 is not shown. Thus, the locking means 24 for the rear panel 7 are clearly visible, as are the guide elements 21, wherein there are two guide elements, and wherein the outer shell 8 is guided on the inner shell 9, thereby forming a sliding guide. The guide element 21 is here fixed to the support leg 18 of the inner housing 9 by a latching connection.

Fig. 5a also shows the latch element 100, i.e. in the uninstalled state. The latching element 100 forms a latching nose 101. In the assembled state of the latching element 100, in the first position of the outer housing 8 of the frame 1, the latching nose 101 engages through the opening 14. The latching element (100) may advantageously be flush with the surface of the outer housing (8, 8'). This allows the outer shell 8 to be fixed relative to the inner shell 9 in an advantageously simple design and/or allows the opening 14 to be closed.

The latching element 100 is designed here according to the principle of a clasp. The clasp is designed as a one-sided lever as shown in fig. 7a and 7 b.

The latching element 100 in fig. 7a and 7b has a base section 102, which is designed here as a sliding receptacle. In this regard, the base section 102 has a trough-like receptacle 103 for supporting the leg 18. The trough-like receptacle 103 is formed by an upper leg 104 and a lower leg 105, each formed by a base section 102. Due to the trough-like receptacle, the latch element can be easily and advantageously pushed onto the support leg 18 of the inner housing 9.

The upper leg 104 has a recess 106. The lower leg 105 has a number (here two) of angular cut-outs 107, from each of which a tab 108 is exposed. The lower leg 105 also has a latching hook 109 corresponding to the recess 106.

When mounting the latch element 100, the latch hook 109 passes through a further latch recess 110 in the support leg 18 corresponding to the latch hook 109 and through the recess 106. This forms a secure and simple latching or snap-on connection, which advantageously makes it easy to mount the latching element 100 on the support leg 18 of the inner housing 9.

Behind the upper leg 104 is a latching section 111. The latching section 111 has a raised edge 112 on the narrow side of the base section 102. The latching section 111 is designed as a one-sided lever. The latching section 111 also has a latching nose 101 which is pressed diagonally at its edge. The chamfer 113, which is produced by the respective contact pressure, makes it easier to attach the latching nose 101 when arriving through the opening 14 of the outer housing 8. The latching section 111 also has an additional angled section 114. The angled section 114 acts as a lift stop for the latching section 111.

Fig. 8 shows an embodiment variant of the latching element 100. In order to avoid repetitions, only the differences or additions to the latching element 100 according to fig. 7a and 7b are described below. In contrast to the latching element 100 according to fig. 7a and 7b, the latching section 111 has a raised edge 112 on the long side of the base section 102. Here, the latching section 111 is designed like a bridge. The latching section 111 also has a latching nose 101 which is pressed diagonally at both edges. The chamfer 113, which is produced by the respective contact pressure, makes it easier to attach the latching nose 101 when arriving through the opening 14 of the outer housing 8.

The latching element 100 according to fig. 7a and 7b or according to fig. 8 is preferably produced from a sheet-or strip-shaped blank as a stamped and bent part. The material used here is preferably so-called stainless steel or rust-and acid-resistant steel. The latch element 100 may also be made of different materials.

Fig. 9 shows a further embodiment variant of the latching element 100. In contrast to the embodiment variant according to fig. 7a, 7b and 8, the latching element 100 is preferably produced in one piece from a plastic material by an injection molding process.

With regard to the geometrical features, the latching element 100 according to fig. 9 substantially follows the embodiment according to fig. 7a and 7 b. In contrast, the latching element 100 according to fig. 9 does not have a receptacle. Rather, the latch element 100 is attached to the support leg 18 of the inner housing 9 via its base section 102 and the latch hook 109. The latching section 111 is also designed here as a one-sided lever, which is integrally connected to the block-shaped middle section 115. The latching section 111 forms a latching nose 101 which has a chamfer 113 on two edges and is rounded with a radius 116 on the other two edges. The latch element 100 also has a wall section 117 which extends lengthwise on the side of the latch element 100 facing the inner housing 9. The wall section 117 and the base section form a guide groove 118. The guide groove 118 is engaged by the guide tab 13 of the outer housing 8 in the assembled state of the latch element 100 with the frame 1.

The latching element 100 shown in fig. 7a, 7b, 8 and 9 can be understood merely as an example. Accordingly, embodiments of the latching element 100 having other geometries, other manufacturing processes, and other materials than those described herein are also contemplated. Basically, the function of covering and latching the opening 27 of the outer housing 8 is provided.
