Description

The invention relates to a supporting device for wall coverings, comprising at least one wall holder, which is fastened with a base plate to a wall and two spaced apart, projecting from the base plate leg, wherein in the legs recesses are provided, in which inserts are arranged, wherein recesses are formed in the inserts, in which pins of a arranged between the legs, plate-like sword are slidably mounted.

Such a support device is from the DE 20 2005 005 779 U1 known. This support allows reliable attachment of wall cladding elements. The known support devices are attached to the base plates of the wall bracket to a wall. The mounted on the wall bracket swords are approximately at right angles from the wall or the base plate of the wall bracket. The free ends of the swords are connected with longitudinal rails. On the longitudinal rails turn plates of a wall cladding can be attached.

Wall coverings may, especially when used on the outer facades of a building, be exposed to large temperature fluctuations. Depending on the material of the plates and / or the longitudinal rails occur in some significant length changes. Therefore, adjacent panels of a wall paneling are not mounted on impact, but have a gap between them. For optical reasons, it is desirable that this joint along a plurality of adjacent plate pairs has a uniform as possible Fugenmaß.

The known support devices are designed so that the sword of a support device is arranged displaceably relative to the wall brackets of this support device. This allows the described Length change of the wall panels or the longitudinal rails of a wall panel can be compensated. In this case, loud setting noises, which can occur in other support devices can be avoided.

The present invention has the object, a support device of the type mentioned in such a way that the installation of a wall paneling is facilitated to the effect that a uniform Fugenmaß can be achieved.

This object is achieved in that the sword along the displacement in at least one reference position relative to the wall bracket is releasably latched.

The reference position makes it possible to position the sword of a carrying device in a certain position relative to the wall holder. With the help of the reference position of the sword also determines the attachment point of a longitudinal rail and a fastened to the longitudinal rail plate of the wall covering.

The sword is not permanently fixed in its reference position relative to the wall holder, but releasably latched. In this way, the reference position along the displacement can be taken in a simple manner by moving the sword relative to the wall bracket. The solubility of the latch in turn allows the sword can move with a longitudinal extension of a longitudinal rail and / or a plate of the wall coverings, so that loud setting noises can be avoided.

A development of the invention provides that the reference position lies between the limits of the displacement forming boundary layers. In this way, it is possible that starting from the reference position, the sword can move in the use position in opposite directions. Thus, it can be ensured both for very low temperatures and for very high temperatures that a sword is displaceable relative to the wall holder, so that it is ensured in the entire temperature range that the wall covering is free of tension in itself.

The support devices may be arranged so that the displacement path is vertical or horizontal. Vertical displacement paths are limited by an upper limit position and a lower limit position. Horizontal displacement paths are limited by lateral limit positions. In the following, further developments for boundary layers are described, the first limit position of which is an upper limit position or a first limit position lateral limit. Correspondingly, the second limit position corresponds to a lower limit position or a second lateral limit position.

According to a development of the invention, the first limit position in the position of use of the carrying device is determined by the contact of a stop element arranged on the sword with the wall holder. Thus, for example, in a simple manner a vertical displacement of the sword can be limited relative to the wall holder upwards. Since the sword and the wall holder are usually formed of metallic materials, a stable arrangement can be provided. For vertical displacement paths, the stop element is preferably arranged on the upper in the position of use of the support device of the sword, which is in the first, upper limit position of the sword in contact with the upper leg of the wall holder. This allows a compact and inexpensive construction.

In the position of use lower limit position of a vertical displacement of the sword can result in a known manner by supporting a sword section. When the sword of a carrying device is in such a limit position, the carrying device can form a fixed bearing in this area. If such a supporting device with other wall cladding elements, For example, longitudinal rails and / or plates is connected, these can be adapted in length only in a remote from this fixed area area.

It is proposed that the latching of the sword takes place relative to the wall holder via latching means formed on the blade and on an insert. In this way, no additional locking means must be provided. This makes it possible to form the support device from a total of four components (wall holder, sword and two inserts).

If the latching means comprise a latching lug and a latching recess, a releasable latching between the wall holder and the sword can be produced in a particularly simple manner.

It is particularly advantageous if the latching lugs provided on an insert, in particular integrally formed therewith, and that the latching recess is provided on the sword. Since the insert can be formed in a known manner from a plastic material, the material of the insert is softer than the metallic material of the sword in the usual way. Thus, a snap-in nose made of plastic can resiliently engage in a locking recess formed on the blade. The Locking recess can be formed in the simplest case by a notch.

In order to create a good compromise between stability and sufficient displacement, it is proposed that the displacement between the boundary layers between 4 and 12 mm, in particular between 6 and 10 mm, more particularly 8 mm. If the reference position, as already described above, lies between the boundary layers forming the boundaries of the displacement path, it is proposed that the reference position be at least approximately midway within the displacement path, ie, for example, a displacement of 4 mm in the position of use after a displacement of 8 mm allowed up and down.

According to a development of the invention, the inserts arranged in the legs are identical. This can be accompanied by the fact that a locking lug provided on an insert is not required. However, this has the advantage that the same insert can be inserted into the recesses of both legs of a wall holder. This facilitates the mounting of the support device, especially in adverse environmental conditions considerably.

A further embodiment of the invention provides that the carrying device has a securing element with which the displacement of the sword between the boundary layers is blocked. In this way, a support device can be provided, which allows along a vertical or a horizontal fixed bearing a longitudinal rail or a plate of a wall paneling. In this way, a fixed reference point can be created, which allows a longitudinal extension of the longitudinal rail or a plate of the wall paneling in this area is not possible. This is accompanied by the fact that a joint adjacent to this fixed point is fixed at least along a boundary. Thus, it can be predetermined in which areas of a plate or a longitudinal rail of a wall cladding expansion or shortening operations take place.

Such a securing element also causes unintentional lifting of the panel of a wall cladding, for example by a strong wind flow can be prevented. This problem can occur especially with comparatively light wall cladding, which can be exposed to strong wind forces in large heights.

It is further proposed for vertical displacement paths that the securing element adjacent to the in Operating position upper leg of the wall holder is arranged. In this way, the sword can be arranged in its lower limit position and thus initiate the initiated by the attached thereto longitudinal rails and plates weight forces in a simple manner by pressure contact in the lower leg of the wall bracket. The securing element prevents movement, which is opposite to the direction of the weight.

The securing element may rest at one end against a boundary of a section of the sword adjacent to a pin and at the other end against a leg of the wall holder. This arrangement allows a direct blocking of the displacement.

An additional development of the invention provides that the securing element is mounted in particular latching on the sword. In this way, the securing element can be mounted particularly easily and without additional tools on the support device. For example, the securing element may have spring arms which engage in a section of the sword formed adjacent to a pin. For mounting, it is sufficient that the spring arms are compressed and inserted into the cutout. By the elasticity of the spring arms spring back this, so that the Securing element is securely attached to the neck of the sword.

The invention further relates to a wall assembly with a first support device described above and with a second support device described above. The support devices are arranged along a vertical or along a horizontal.

It is proposed for such a wall arrangement that at a reference temperature, the sword of the first support device in its first, for example. Lower limit position is arranged and that the sword of the second support device is arranged in its reference position. In this way, for arranged along a vertical support devices, the first support device can absorb the weight of a wall panel, while the sword of the second support device can move from the reference position up or down to compensate for changes in length of the wall panel can. For arranged along a horizontal support devices, the weight is distributed evenly.

It is particularly advantageous if the first support device is a securing element described above having. In this way, the sword of the first support device is secured in its boundary position.

The first support device may be arranged at the top with respect to a vertical and the second support device at the bottom. In this way, the weight forces of a wall cladding are accommodated in an upper area, so that the longitudinal rail or panel of the wall cladding attached thereto is suspended. The lower, so the second support device, then allows the length compensation of the wall covering already described.

In principle, a support device, the sword is arranged in a boundary position, form a fixed point storage of a wall covering. The positioning of this fixed point bearing is in principle arbitrary. A support device, the sword can move out of a reference position, then allows a defined length compensation of the wall covering in the direction predetermined by the displacement of this support device direction.

The invention also relates to a wall arrangement comprising a longitudinal rail extending parallel to the vertical or the horizontal and connected to the sword of the first support device and connected to the sword of the second support device.

Finally, the invention relates to a wall cladding with at least two wall arrangements described above, wherein the longitudinal rails are attached at least in sections between these extending plates.

Further advantages, features and details of the invention will become apparent from the following description in which, with reference to the drawing, a particularly preferred embodiment is described in detail. The features shown in the drawing and mentioned in the claims and in the description may each be essential to the invention individually or in any combination.

According to FIG. 1, a wall holder 2 of a carrier device has a base plate 4, from which a leg 6, which is upper for vertical displacement in the position of use, and a leg 8 which is lower in the position of use protrudes. In the legs 6 and 8 circumferentially closed recesses 10 and 12 are provided, which are indicated by dashed lines in Figure 1.

Corresponding to the assembly direction designated by 14 in FIG. 1, an insert 16 shown in FIG. 2 can be inserted into the recess 12 of the leg 8. The insert 16 is locked in the recess 12 by means of locking elements 18. The insert 16 also has a latching nose 20 pointing in the direction of the upper leg 6.

In Figure 2, a plate-like sword 22 is shown, which has an upper pin 24 and a lower pin 26th having. Adjacent to the pins 24 and 26 are cutouts 28 and 30 are formed.

On the upper pin 24, a stop element 32 is formed, whose function will be described below. The sword 22 also has a latching recess 34, which is arranged in the region of the pin 26.

The sword 22 can be joined to the wall holder 2 according to the joining directions designated 36 and 38. For this purpose, the upper pin 24 of the sword 22 must be inserted into the recess 10 of the upper leg 6. Subsequently, the sword 22 can be rotated so that it assumes the position shown in Figure 3.

FIG. 3 shows a further joining direction 40. The sword 22 can be moved according to this joining direction by the lower pin 26 of the sword 22 is immersed in a formed in the insert 16 recess 42. This recess is shown in FIG. The sword 22 can be moved in the joining direction 40 within the recess 42 until the locking lug 20 of the insert 16 engages with the locking recess 34 of the sword 22 in engagement. The sword 22 is then in a reference position I described in more detail below, also shown in FIG.

With reference to FIGS. 4 and 6, an insert 44, which is identical to the insert 16, can be inserted into the recess 10 of the upper leg 6. Also, the insert 44 is held with locking elements on the recess 10 of the leg 6. When mounting the insert 44 in the recess 10, the upper pin 24 of the sword 22 can dip into a recess 44 formed in the insert 44. This is shown in FIG.

After mounting the insert 44 results in a support device shown in Figure 5 50. The sword 22 of the support device is shown in a central position by solid lines. This corresponds to the reference position I, in which the sword 22 and the wall bracket 2 are locked together. From this reference position I out the sword 22 can be moved along a displacement path indicated in Figure 5 with 48. In this case, the sword 22 occupy a dashed line indicated first, upper limit position II. In this limit position II, the stop element 32 comes into contact with the upper leg 6.

The sword 22 can from the reference position I also in a second, lower, also shown by dashed lines Border III are moved. In this limit position, the boundary of the cutout 30 comes into contact with a force-receiving surface 51 shown in FIG.

The sword 22 is thus releasably latched to the wall bracket 2. From the reference position I out the sword can be moved along the displacement path 48 and occupy positions II and III as boundary layers.

FIGS. 7 and 8 show various views of a securing element, designated overall by reference numeral 52. This has a plate-shaped base 54, from which a generally designated 56 detent body (see Figure 8) extends. The latching body 56 has two spring arms 58 and two adjacent to the base 54 arranged counter-holder 60. With reference to FIG. 7, the securing element 52 furthermore has an upper material section 62 and a lower material section 64.

In order to be able to arrange the securing element 52 on a carrying device 50 according to FIG. 6 in order to form a carrying device 50 'according to FIG. 9, the sword 22 is first moved out of its reference position I into its lower limit position III. Subsequently, the securing element 52 are inserted into the opening with a free end 66 of the locking body 56, which forms the cutout 28 in the lower limit position III of the sword 22 (see Figures 5, 6 and 9). For this purpose, the spring arms 58 are compressed until they engage behind the sword 22 latching. In this case, the securing element is held without play on the sword 22 by means of the counter-holder 60. The material portions 62 and 64 are dimensioned so that the material portion 62 abuts against the leg 6 and the material portion 64 at the lower end of the cutout 28 of the sword 22nd

In Figure 10, a plurality of wall assemblies 68 are shown, each comprising an upper support device 50 'with a securing element 52 and a lower support device 50 without securing element 52. Each wall assembly 68 further includes a longitudinal rail 72, which in a known manner with the sword 22 of Support devices 50 and with the sword 22 of the support device 50 'are connected. The wall assemblies 68 together form a wall panel 70, which in addition to the longitudinal rails 72 and plates 74, which are fixed in a known manner to the longitudinal rails 72.

Figure 11 shows the wall panel 70 in a sectional side view with a wall 76 at which the Wall holder 4 of the support devices 50 and 50 'are fastened via dowels / screw 78.

From Figures 10 and 11 it can be seen that the swords 22 of the upper support devices 50 'are in their lower limit position III. On the other hand, the swords 22 of the lower support devices 50 occupy the reference position I, in which the latching means 20 and 34 shown enlarged in FIG. 4 are in engagement with one another.

The described arrangement makes it possible that the longitudinal rails 72 at the height of the support devices 50 'fixed, that is held without possibility of displacement. On the other hand, the swords 22 of the lower support devices 50 can move along the displacement path 48, designated 48 in FIG. 5, in the direction of their upper limit position II or in the direction of their lower limit position III. As a result, changes in length of the longitudinal rails 72 and / or the plates 74 can be compensated. In this case, the position of the longitudinal rails and the plates 74 at the height of the support devices 50 'does not change, so that a preferred direction is specified, in which a length compensation takes place.
