Description

The invention relates to a profile strip for creating a wall suitable for receiving hanging articles, with tongue and groove-like extensions for joining together several sections of the profile strip. In the interior of business premises, walls or wall elements are frequently used which have hanging slots which run horizontally at a uniform distance from one another. There is a large variety of hanging items, in particular goods carriers, which can be placed anywhere with an extension. The goods are then presented on these goods carriers.

A profile bar of the type described above is known. It consists of a wooden profile, which has been brought into the desired shape by a milling process. Tongue and tongue-like extensions on both longitudinal edges of this wooden profile strip allow several sections to be placed one above the other and anchored with a support wall, so that ultimately the wall or the wall element for hanging the hanging article is created. The known wooden profile strip is milled from solid wood and has a continuous front surface and a continuous rear side, so that the suspension slot is only created between two such profile strips. It goes without saying that a nose-like projecting extension must be provided at one end of this profile strip so that the hanging articles can reach behind this extension when hooking in accordingly. The individual sections of the profile strip are glued and / or screwed to the support wall. It is advantageous in this known Profile strip, that by using the material wood, as it were, a completely attractive surface is created, which only requires a small amount of post-treatment. A wall can also be compiled and built up comparatively easily from these known profiled strips, for example in self-construction. To produce the wooden profile strips, it is sufficient to mill or plan the wooden strips accordingly. The disadvantage of this, however, is that such a wall is only suitable for absorbing low loads, because the attachments of the hanging articles which engage behind the nose-like extensions often cause the extension to break away from the wall when overloaded, as a result of which the wall is practically no longer can continue to be used. A high-wage treatment is also required to produce high-quality surfaces. The assembly of such a wall from such wooden profile sections is generally associated with a certain amount of effort, in particular when the sections must be connected to the support wall by means of concealed screwing.

To produce less sensitive surfaces, it is also known to start from a wooden profile strip and to encase it with plastic by pressing the profile strip out through a nozzle and thereby encasing it with the plastic. The result is a smooth, easy-care surface. The stability of such a profile strip and the wall created from it is comparatively low. The disadvantage of breaking out in the event of overload is still present.

In order to manufacture such walls or wall elements, which are sometimes also referred to as diaphragm walls, it is also known to start from a chipboard and to mill into these grooves, which are then expediently lined with metal profiles to be inserted in order to counter the risk of breakouts. This creates the Advantage that the chipboard takes over the function of the support wall, so to speak, so that a separate attachment between a profile and a support wall is not required. This also results in good resilience, especially when using metal profiles, which distribute the forces exerted by the hanging articles over a larger area. However, the necessary insertion of the metal profiles and also a subsequent surface treatment, at least on the front, are disadvantageous, so that ultimately a wall constructed in this way does not meet all requirements insofar as the possibilities for variation and adaptation are limited in this respect.

The invention has for its object to show a profile strip of the type described, which nevertheless allows inexpensive manufacture and easy assembly a high load capacity.

According to the invention, this is achieved in that the profile strip is designed as an extrusion profile made of plastic or aluminum, has several chambers serving for stiffening and has on one side at least one suspension slot, which is then arranged halfway up the front of the profile strip, and in that Connect the front webs of the same height to the hook-in slot on both sides, which are set back by half the width of a hook-in slot compared to the tongue-and-groove extensions. The new profile strip is not a solid component, but is produced as a profile by extrusion, the cross section of the profile being largely hollow and only Chambers are formed, which serve for stiffening. Good strength is achieved at the same time with little use of material. In the extrusion process, excellently suitable and resistant surfaces that do not require any post-treatment can be automatically created. By forming a complete suspension slot on one side, which is arranged approximately in the central region of the height of the profile strip, a profile strip is created which, as compared to the previously known profile strip made of wood, is of double width or double height, so that in addition to the fully designed hook-in slot also automatically creates another hook-in slot when you plug together sections of this profile strip in the transition area between two adjacent profile strips. If only one suspension slot is provided on the front of the profile strip, then this is arranged halfway up the profile strip and the second suspension slot is then formed in the association between two adjacent profile strip sections. For this purpose, the back offset of the end of the front webs is half the width of a suspension slot. However, if the profile strip is comparatively higher or if it has more complete suspension slots on the front, the same applies accordingly. If two complete slots are provided on the front, then these are each arranged at 1/3 and 2/3 of the height of the profile strip. In any case, the assembly effort is simplified and there is an increase in strength not only on the profile strip, but also on the entire wall. This opens up completely new possibilities and, above all, a design variant in which a complete, continuous support wall is eliminated. The new profile strip can be manufactured inexpensively and automatically gets a scratch-resistant surface. She instructs low weight with high load capacity and can be used and used on site when creating the wall. Finally, the profile strip produced in the extrusion process has a high degree of dimensional accuracy and therefore allows the tongue-and-groove extensions to be produced with tighter tolerances, so that the individual sections of the profile strip can not only be joined together, but actually also mutually mutually stable when plugged together support.

At least one fastening groove can be provided on the side opposite the suspension slot, furthermore a continuous central web can be provided approximately in the longitudinal center plane, on which the chambers are arranged extending to both sides, one chamber open in the insertion slot and another chamber open in the mounting groove merges. The cross section of the profile strip is built up on the continuous central web, with the chambers extending to both sides and the various webs being stiffened in the manner of a truss. The profile strip is thus highly stable and is suitable to withstand high loads due to the weight of the goods on the hanging articles.

Due to the arrangement of at least one fastening groove, the connection to a carrier wall is considerably easier than a gluing or screwing process. It is particularly advantageous to use suspension brackets which engage from behind in the mounting groove from a support wall, a column arrangement or the like. The sometimes necessary screwing for fastening the profile strip to a support wall is completely eliminated. Instead, the mounting brackets can first be attached to the support wall and it is possible to place the sections of the profile strip on these mounting brackets, the mounting brackets coming into operative connection with the fastening groove.

It is particularly advantageous if a continuous back web and an interrupted central web are provided, the central web being arranged in each case in the region of the suspension slots; at the ends of the middle webs there are transverse webs which connect the front webs with the back webs. This special design proves to be advantageous in that a particular stiffness and strength is achieved precisely in the area of the suspension webs, that is, where the suspension articles are suspended and thus the load is applied. There is no longer any danger of breaking out as with the wooden profile strip. On the other hand, there is also a firm bond of the assembled profile sections on the wall. Separate screen walls or support walls are no longer required. Of course, the built-up wall must be fastened to a room wall, a column arrangement or the like by any fastening means.

Building on the central web, one of the chambers arranged to the rear can be offset in height from the insertion slot into the fastening groove, so that back webs of unequal length are formed. This means that the insertion slots are in any case offset in height from the fastening grooves, so that there is no place on the profile strip at which the cohesion takes place exclusively via the central web.

The back webs can end flush with the center web, the tongue and groove extensions being arranged between the end regions of the center web and back webs. The plug-in connection thus takes place in an area which is beyond the direct plan view of the front or front. The tongue and groove-like extensions can be used as snap connection Elements are designed so that it is possible to join the sections of the profile strip by a sliding process transversely to their longitudinal extent.

The chambers adjoining the back webs can be made wider than the chambers formed on the front webs, so that in this way the chamber adjoining the back webs with the central web also take over the function of a support wall.

Several suspension slots can be provided on the front and several fastening grooves can be provided on the rear. It is understood that the profile strip is then designed to be correspondingly wider. In addition to the double arrangement with ultimately two hanging slots in the association, a triple unit and a quadruple unit are possible in particular. The quadruple unit thus has three fully designed hook-in slots on the front of the profile strip and some fastening grooves on the back.

The central web can have a groove in the area of the insertion slot or slots, which can serve as a marking for the use of fastening screws if the new profile strip is nevertheless to be connected to a support wall by a screwing process and does not take advantage of hooking angles in connection with the fastening grooves will.

At least one front web can be connected to a back web via a continuous cross web. This serves to stiffen and increase the statility of the cross section of the profile strip.

The central web can have interruptions, wherein the cross webs can be provided at the ends of the interrupted central web, whereby the cross webs with the Form the front web and the back web on the one hand and with the middle web and the back web on the other. A substantial material saving is achieved by means of an intermittent central web. The arrangement of the cross bars at the ends of the central web creates chambers which give the profile strip great stability.

The back web can be continuous and the center web can be arranged in the region of the suspension slot. Through the continuous design of the back web, an even greater strength of the profile strip is achieved. Such a profile strip can be fastened to the support wall by screwing. A groove is provided on the center bar in the area of the suspension slot for marking the fastening screws. Other types of fastening of the profile strip with the support wall are also conceivable. A suspension profile can thus be guided through one or more of the chambers which are formed by the transverse web, the front web and the back web.

Angle pieces can advantageously be provided for insertion into chambers of the profile strip, which have hooks for hanging in slot rails. This can be used in conjunction with slotted rails to create a very stable wall, which is used in a very decorative way to accommodate the hanging articles and the goods to be fastened to them. It is also possible to break through the continuous rear wall of the profile strip sections at certain intervals in order to create holes through which the angle pieces can be inserted laterally into the chambers. Protruding ribs can be provided in the chambers for the optional insertion of the angle pieces. The distance of the wall formed from the profile strip sections to the fastening point is thus varied. In addition, the above pips serve to stiffen the profile strip and the wall.

At their two ends, the front webs can have mutually assigned, protruding projections which form undercuts for anchoring insertion strips. The slide-in strips can be printed or colored in various ways so that the color impression of such a wall can be varied very quickly. The insertion strips can also consist, for example, of a photo cut into strips. Since the slide-in strips are usually only used to change the decorative appearance and the surface of the wall - with the exception of the hanging slots - they can be made comparatively thin.

As a rule, the front webs will be flat. However, it is also possible to assign a curved surface, convex or concave, or a stepped surface, or to form the surface in this way. This also creates decorative effects.

The profile strip shown in Figure 1 is designed as an extrusion profile 1 made of plastic and has a continuous central web 2, which is arranged somewhat offset to the longitudinal center plane of the profile strip. Front webs 4 are held via webs 3, which in this respect have identical dimensions and which are also arranged symmetrically. The two front webs 4 form the front view of the profile strip and are thus arranged on the front 5. The two front webs protrude above webs 3 and enclose between them a complete suspension slot 6, which is used to insert a corresponding foot of a suspension article here and to engage behind one of the two projecting front webs 4. Such hanging articles and the way in which they are used are known and therefore need not be explained. However, the two front webs 4 end set back relative to the center web 2 half the width of a suspension slot 6, so that in the association at the transition point between two adjacent sections of the profile strip still a suspension slot 6 is created.

Two back webs 8 and 9 are formed over webs 7, which face the rear side 10 and have unequal dimensions, in particular unequal heights. In this way, a fastening groove 11 is formed in the area of the rear side 10, into which a suspension bracket fastened to a carrier wall can easily engage. Such suspension angles are easily imaginable due to the shape of the fastening groove 11 and the protrusion of the three ends of the back webs 8 and 9, so that a graphic representation can be dispensed with. The central web 2, the web 3 and the front webs 4 form or limit chambers 12, which are designed to be closed and, as a closed hollow profile, produce a considerable stiffening effect. An open chamber 13 merges into the insertion slot. Correspondingly, closed chambers 14 and an open chamber 15 are formed between the central web 2, the webs 7 and the back webs 8 and 9, which merges into the fastening groove. Otherwise, the central web is connected to the back webs 8 and 9 above and below in the manner shown, a spring-like extension 16 and a groove-like extension 17 being formed here, so that in this way adjacent sections of the profiled strip are snap-connected 16, 17 can be snapped together. It is understood that this snap connection 16, 17 is invisible, particularly from the front side 5, when plugged together. It can also be seen that the suspension slot 6 is arranged offset in height in the middle of the front side 5 with respect to the fastening groove 11.

From a number of sections of profile strips according to Figure 1 can create a wall 18, as shown in Figure 2. A support wall or a frame-like structure, which is also provided with rollers 19, for example, can be used. Such a wall 18 can be covered on both sides with sections of the profiled strip or can be designed from such, it also being possible to dispense with a support wall and to establish a direct connection between the two sides via the fastening grooves and corresponding angles or rail pieces. It goes without saying and is readily conceivable that, of course, also fixed walls, even with only one-sided equipment, can be created with the profile strip according to FIG. 1.

FIG. 3 shows a second embodiment of the profile strip, which in itself is constructed similarly to the exemplary embodiment in FIG. 1. However, the profile strip according to FIG. 3 is based on a triple unit and is therefore of wider design. It has two fully designed hook-in slots 6 and then receives a third hook-in slot in the association. The four fastening grooves are formed on the back and a continuous cross piece 20 is provided in the middle of the cross section of the profile strip. In the area of the fully formed suspension slots 6, the central web 2 has a groove 21 which serves as an aid for the use of fastening screws if no use is to be made of fastening angles in the region of the fastening grooves.

FIG. 4 finally shows an embodiment of a quadruple unit with three complete suspension slots 6 on the front 5 and three fastening grooves 11 on the rear 10. Otherwise, the design is corresponding.

5 shows a further embodiment of the profile strip. The main difference from the embodiment of FIG. 1 is that the back web 8 is continuous and the center web 2 has interruptions. The central web 2 is arranged in the region of the suspension slot 6. The groove 21 is located on the central web 2. The transverse webs 20 are arranged at the ends of the central web 2. The transverse webs 20 connect the front web 4 to the back web 8. The cross webs 20 form chambers 22 in connection with the front web 4 and the back web 8, or a chamber 23 with the back web 8 and the central web 2. Otherwise, the design is corresponding of course, a multiple unit can be produced on the basis of this profile strip.

6 shows an embodiment of a suspension profile 24. The suspension profile 24 has two side walls 25, a front wall 26 and a rear wall 27. The side walls 25 and the front wall 26 have the same length in cross section, whereas the rear wall 27 has a greater length. The cross section of the hanging profile is therefore rectangular, the rear wall 27 being provided with an extension 28. Lugs 29 are arranged on the rear side 10 of the hanging profile 24. The hanging profile 24 can be made of metal or also of plastic. To attach the profile strip, the hanging profile 24 is pushed into one of the chambers 22. In this case, the hanging profile 24 has a lateral projection over the profile strip, so that the lugs 29 can engage in corresponding rails. Such rails are known, so that on whose representation can be omitted. They usually have a U-shaped cross-section and have aligned slots. These rails are connected to the support wall by means of screws or other suitable fastening means. The lugs 29 of the suspension profile 24 then engage behind the wall of the rails, as a result of which a firm and secure connection of the profile strip to the support wall is established.

7 shows a top view of the hanging profile 24. The front wall 26 is set back by a distance 30 from the end of the rear wall 27. In the area of the distance 30, the lugs 29 are arranged on the back 10 of the hanging profile 24. The distance 30 is selected so that when the suspension profile 24 is fastened to the known rails, the front wall 26 and the side walls 25 are flush with the profile strip. This gives the attachment of the profile bar by means of hanging profile 24 a pleasing appearance.

The profile strip shown in FIG. 8 is also designed as an extrusion profile 1 and has, at intervals, that is to say with interruptions, arranged central webs 2, to which three front webs 4, which form the front side 5 of the extrusion profile 1, are fastened and held via webs 3. Hook-in slots 6, which have the width x, are also formed here between the front webs 4. The top and the bottom front web 4 of the profile strip end set back by half the width (x / 2) relative to tongue-and-groove extensions 16 and 17, so that there is an insertion slot of width x at this point between two adjacent profile sections . The profile strip also has a continuous back web 8, which is connected to the front webs 4 via cross webs 20 or webs 3. In this way, chambers 22 and 23 are provided, similar to the embodiment of FIG. 5. The front webs 4 are flat on their surface facing the front 5. At this point you could also be convex or concave or stepped be trained. The front webs 4 end in extensions 37 and 38, which face each other and receive an insertion strip 39 between them in the undercut formed in this way, by using or replacing the surface of the extrusion profile 1 and the wall created therefrom can be easily changed.

For fastening a wall composed of several such sections according to FIG. 8, for example, to a flash rail 33 (FIG. 10), angle pieces 31 are used, as is shown by way of example in FIG. 8 in dashed lines. Such an angle piece 31, as shown in perspective in FIG. 9, has a plate 34 and a hook 32 projecting at right angles, with the aid of which it can be suspended in the slot rail, the hook 32 being able to have a plurality of recesses for optional suspension. Freely ending ribs 35 and 36 are provided within the chamber 22, between which the plate 34 of an angle piece can be inserted in three different positions (FIG. 8), so that the distance from the slotted rail 33 can also be selected or adjusted in different ways .

FIG. 11 illustrates once again how the decorative appearance of the extrusion profile 1 and thus the wall formed from such sections can optionally be changed by inserting strips 39. These insertion strips 39 generally consist of printed paper, by means of which, for example, a marble-like effect or a linen structure or only the color design of the wall can be produced or easily changed.
