Mounting bracket for attaching visual profiles

Description

[0001] The invention relates to a retaining element for fastening visible profiles.

[0002] German patent DE102005002054A1 discloses a facade system for fastening visible profiles for wall and / or ceiling cladding, connected via longitudinal grooves and tongues, using retaining elements. These retaining elements engage in the grooves of the visible profiles with a hook-shaped rib projecting from the base plate. This hook-shaped rib also provides a stop-limited support for the visible profile held in the receptacle, thus compensating for thermal expansion. The retaining elements themselves are mounted to the wall or ceiling using fasteners that engage in their openings. A disadvantage of this system is that even slight dimensional deviations in the visible profiles, for example, caused by manufacturing tolerances, result in a significant amount of play in their fastening, compromising the stability of the device.Material-related shrinkage and swelling – especially after several weather cycles – can also lead to irregular gaps with this type of installation, which can adversely open the cladding and thus endanger its function.

[0003] Furthermore, a retaining element between two visible profiles is known for facade systems from DE103007056824A1. This retaining element comprises a base plate and two parallel webs projecting from the base plate. A first web is hook-shaped and engages in a longitudinal groove on the lower narrow side of the first visible profile, while the second web rests against and is attached to an upper narrow side of the second visible profile. Although this second web can cover the point of attachment to the second visible profile, there is an increased risk of splitting at this attachment point due to the driving in of fasteners. This proves particularly detrimental to the stability of the visible profiles and thus to the durability of the facade.

[0004] A retaining fitting for holding at least one base plate is known from EP2096233A2. The retaining fittings have claws open on opposite sides. The base plates lie, for example, next to each other in their impact area with a distance adjustable by a spacer stop. NL1013914C2 discloses a retaining element according to the preamble of claim 1.

[0005] The invention is therefore based on the objective of creating a retaining element, starting from the prior art described above, that is tolerant of manufacturing- and / or temperature-related dimensional deviations in the visible profiles – yet still ensures their stable mounting. Furthermore, the retaining element should prevent undesirable gaps from forming between the visible profiles and enable easy handling.

[0006] The invention solves the problem by providing the retaining part with at least one third web projecting from the base plate, wherein the third web, which is designed to engage in a groove on the rear broad side of the second visible profile, together with the second web forms a snap connection for fastening the second visible profile to the retaining part.

[0007] If the retaining element has at least one third rib projecting from the base plate, wherein the third rib, designed to engage in a groove on the rear broad side of the second visible profile, together with the second rib, forms a snap connection for attaching the second visible profile to the retaining element, a particularly stable connection can be created between two adjacent visible elements using a single retaining element. In contrast to the prior art, the second visible element can also be held on the retaining element without fasteners penetrating the material, thus preventing damage and eliminating the risk of adverse weather conditions at the connection points. This extends the natural durability and therefore the service life of the visible profiles.Furthermore, such a snap connection can significantly counteract gap formation caused by manufacturing and / or temperature-related dimensional deviations (for example, due to shrinkage and swelling) in the visible profiles – for example, by means of elastic deformation at the spring-loaded snap element – ​​which can reliably maintain the technical cladding function of the visible profiles. In addition, this snap connection can also allow for the relatively simple and quick removal of the visible profiles – for example, for cleaning purposes – thus simplifying the handling of the retaining element and, consequently, the facade.

[0008] If the second bridge forms the spring-loaded snap element of the snap connection, the second visible profile can be quickly and easily connected to the holding part and thus held securely in place. This is achieved because the spring action of the snap element compensates for any shrinkage or swelling of the held visible element. Furthermore, the spring-loaded snap element allows for the easy replacement or removal of damaged visible elements, for example, for cleaning purposes. This results in a stable and easy-to-handle holding part.

[0009] Mutual support of the webs under load, for example from wind loads on the visible profiles, can be achieved if the second web is curved in the opposite direction to the hook-shaped first web. Furthermore, this allows gaps to be compensated for by mutual bracing, which can contribute to improved cohesion of the visible profiles and increased stability of the supporting element.

[0010] If the second rib is designed to be attached along a lug on the upper narrow side of the second visible profile, the holding surface for the snap connection can be enlarged and thus made more robust. In particular, if such a lug on the upper narrow side adjoins the rear broad side of the visible profile, it can be concealed by the retaining profile and thus protected from the elements. Furthermore, if this rib is limited to this area of ​​the lug, shrinkage and swelling of the visible profile held by a snap connection in other areas can be permitted, thus largely relieving the snap connection of resulting mechanical stresses.

[0011] The snap connection can be made more mechanically resilient if two spaced-apart and parallel second webs (9) form the snap connection with the third web.

[0012] If the third web and the recess between the two parallel second webs are provided, the overlapping function of these second webs can significantly improve the hold of the two visible profiles on the holding element. The stability of the holding element can thus be further increased.

[0013] If the third web is formed by at least two legs that are offset from each other, particularly in the longitudinal direction of the base plate, manufacturing tolerances at the groove on the rear broad side of the second visible profile can be compensated for particularly elegantly. Furthermore, this can increase the tolerance to shrinkage and swelling of the visible profiles, which can further increase the stability of the retaining element.

[0014] A further improvement to the snap connection is possible by having the base plate terminate in at least one tongue that extends laterally to the third web. This portion of the base plate, projecting beyond the third web, can help center the visible profile in the area of ​​the snap connection, thus preventing unwanted loosening of the connection. This can be further improved if the base plate terminates in tongues that extend beyond the end of the third web on both sides.

[0015] If the opening in the base plate is located between the first and second webs, the mounting brackets – for example, on a wall or ceiling – can be installed without obstruction from the connecting elements intended for the visible profiles. Furthermore, this design feature allows the mounting bracket to be pre-attached to a visible profile via its snap-fit ​​connection before its own installation on the wall or ceiling, significantly simplifying the placement and alignment of the mounting brackets. This further improves the handling of the visible profiles and, consequently, their installation.

[0016] Mounting the retaining element, for example on the wall or via a possible substructure on the wall, can be facilitated if a raised section of the first web acts as a guide for a fastener to be inserted into the opening. This makes positioning and inserting the fastener, for example into the wall or ceiling, much easier. For this purpose, the raised section of the web could be aligned with the edge of the opening.

[0017] If the raised section of the first web springs back in the area of ​​the opening of the base plate, the fixing of the base plate with the fastening means is not hindered by the guide formed by the raised web section - rather, this even allows for fine positioning by moving the base plate.

[0018] If the first web ends in an outwardly curved section, inserting the upper visible profile and thus its installation can be facilitated. This can improve handling of the retaining element during assembly and also protect the first web from damage caused by incorrect positioning of the visible profile. The stability of the retaining element can thus be increased.

[0019] The retaining element can be further simplified in the area of ​​the mounting if the base plate terminates in a mounting tongue extending laterally to the first web, which together with the first web forms the mounting. If the mounting tongue extends further beyond the first web, the insertion of the upper visible profile and thus its assembly can be further facilitated.

[0020] The mounting can be made more robust if the base plate has two spaced-apart and parallel first ribs and terminates in a mounting tongue running between these two first ribs, in particular a continuing rib, which together with the two first ribs forms the mounting.

[0021] The retaining element according to the invention can be used particularly advantageously in a facade system in order to attach several visible profiles to a wall or to a wall via a substructure.

[0022] The figures illustrate the invention in more detail by means of several embodiment variants. They show Fig. 1 a sectional view of a facade system attached to a wall with retaining elements according to a first embodiment and visible profiles, Fig. 2 an enlarged section of the Fig. 1 , Fig. 3 a top view of the holding part after Fig. 1 , Fig. 4 a top view of a holding part according to a further embodiment and Fig. 5 a cross-sectional view through the after Fig. 4 second retaining part shown.

[0023] According to Fig. 1 A sectional view shows a facade system 1 to which several visible profiles 2, 3, or facade profiles, are attached to a wall 4. The following Fig. 1The visible profiles 2, 3 shown here are made of a solid material, for example, wood or a wood-like material, although hollow profiles are also generally conceivable. The facade system 1 includes several retaining elements 5 for mounting the visible profiles 2, 3. Each retaining element has a base plate 6 with an opening 7 and several webs 8, 9, 10 projecting from the same side of the base plate 6. The opening 7 serves to drive a fastener 11, namely a countersunk screw as shown here, into the wall 4 to mount the retaining element 5 to the wall 4. However, other means of mounting the base plate 6 to the wall 4, either detachable or non-detachable, are also conceivable.

[0024] It is generally mentioned that the retaining part 5 also has a Fig. 1 The substructure, which is not shown in detail, may be mounted, for example, on wall 4 or on a ceiling.

[0025] The webs 8, 9, 10 serve to hold the visible profiles 2, 3 on the retaining part 5 in order to attach them to the wall 4. For this purpose, the first web 8 is hook-shaped so that it can engage in a longitudinal groove 12 on the lower narrow side 13 of the visible profile 2 (the upper side relative to the respective retaining part 5) and thus hold it. The first web 8 also forms a receptacle 14 together with the base plate 6 for the stop-limited support of the first visible profile 2 received in the receptacle 14, as shown in the Fig. 2 in detail. The second web 9, on the other hand, lies against the second visible profile 3 provided below the first visible profile 2 - namely against its upper narrow side 15, in that this second web 9 is attached to this upper narrow side 15 of the second visible profile 3.

[0026] Unlike the prior art, the second web 9 is not attached to the upper narrow side 15 of the second visible profile 3. According to the invention, a snap connection 16 is provided on the retaining part 5. For this purpose, the retaining part 5 has a third web 10 that engages in a groove 17 on the rear broad side 18 of the second visible profile 3. It is generally noted that the rear broad side 18 is opposite the visible broad side of the visible profile 3. This third web 10 then works together with the second web 9 to form the snap connection 16, thereby detachably attaching the second visible profile 3 to the retaining part 5. Damage to the second visible profile 3, which would otherwise be necessary when attaching or fixing the web to a visible profile by driving in fasteners 11, such as wood screws, staples, or paper clips, can thus be avoided.The risk that the retaining part 5 adversely affects the stability of the visible profiles 2, 3 is therefore not present.

[0027] Furthermore, this method allows for particularly easy assembly and maintenance of visible profiles and retaining elements.

[0028] By, as in Fig. 2 The fact that the second web 9 forms the spring-loaded snap element of the snap connection 16 provides a particularly advantageous compensation for shrinkage and swelling of the visible profile 3, which increases the stability of the facade system 1 for fastening the visible profiles 2, 3.

[0029] Furthermore, the second web 9 is curved in the opposite direction to the hook-shaped first web 8 in order to brace both supports of the visible profiles 2, 3 against each other. This compensates for any manufacturing tolerances between the support element 5 and the visible profiles 2, 3 – and ensures secure attachment of the visible profiles 2, 3 to the wall 4.

[0030] Furthermore, the Figure 1 and 2 It can be seen that the visible profiles 2, 3 each have a lug 19, which forms on the upper narrow side 15 of the visible profiles 2, 3 and transitions into the rear broad side 18 of the respective visible profile 2, 3. The second web 9, which has a curved profile for this purpose, is attached to this lug 19. This increases the positive fit with the visible profile 3, which benefits the mechanical stability of the snap connection 16. The second web 9 is limited to this area of ​​the lug 19, which allows for shrinkage and swelling of the visible profile 3 in the areas left free by the web 9, thus relieving stress on the snap connection 16.

[0031] Again Fig. 3As shown, the third web 10 is formed by two legs 20, 21 of the base plate 6. These legs 20 and 21 are not only offset from each other in the longitudinal direction of the base plate 6, but are also arranged side by side at a distance. This allows manufacturing tolerances at the groove 17 of the visible profile 3 to be compensated for particularly well.

[0032] In addition, the second bridge 9 is designed twice in order to grip the visible profile 3 with a wide handle and thus improve the support of the visible profile on the holding part 5.

[0033] This snap connection 16 can therefore ensure a particularly secure hold of the visible profile 3 on the retaining part 5.

[0034] How also the Fig. 3As can be seen, the third web 10 and the receptacle 14 are provided between the two parallel second webs 9 to utilize the wide support of the retaining part 5 on the visible profile 3 as an anti-rotation device for the snap connection and for the receptacle. This gives the retaining part 5 high stability.

[0035] Furthermore, base plate 6 ends as shown in Fig. 3 This can be seen in the two tongues 22, 23 extending on both sides to the third web 10, which facilitates the handling of the snap connection. This also serves to ensure the safe spacing of the visible profiles 2, 3 from the wall 4 or from the substructure.

[0036] Furthermore, it is possible to mount the retaining element 5 to the wall 4, or to the wall 4 via a substructure (not shown), even after it has snapped into place with the second visible profile 3. For this purpose, the opening 7 in the base plate 6 is provided between the first web 8 and the second web 9. Moreover, the positioning of the retaining element 5 relative to the other visible profile 2 is automatically ensured by the snapping of the retaining element 5 to the visible profile 3 – which significantly simplifies the installation of the facade system 1.

[0037] The web 8 has a raised web section 24 that is specially adapted to the fasteners 11. This section runs approximately towards the edge of the opening 7 and can thus form a guide for the fastener 11, which is driven through the opening 7 into the wall 4 or substructure. In addition, this raised web section 24 is recessed in the area of ​​the opening 7 of the base plate 6 to provide sufficient space for various screw head shapes.

[0038] Accordingly Fig. 2 It can also be seen that the first web 8 terminates in an outwardly cranked web section 25, thus forming a guide that facilitates the mounting of the upper visible profile 2. Furthermore, this reduces the deformation of the first web 8 during the mounting of the upper visible profile 2, which improves the stability of the holder part.

[0039] Furthermore, the Fig. 3It can be deduced that the base plate 5 terminates at one end in a receiving tongue 26. This receiving tongue 26, which extends laterally towards the first web 8, together with the first web 8 forms the receptacle 14, and its design, which continues towards the first web 8, significantly simplifies the insertion of the upper visible profile 2 into the receptacle 14 or provides a guide for this purpose.

[0040] The holder part 5 according to the invention can, for example, be made of a metal material. For example, the holder part 5 can be manufactured from a formed sheet metal, for instance by punching and subsequent bending of the various webs 8, 9, 10.

[0041] That after Figs. 4 and 5 The alternative retaining part 50 shown, unlike the one shown after the Figures 1 to 3The first retaining element 5 shown comprises two parallel first webs 8, spaced apart from each other. Between the two webs, the base plate 5 extends into a continuous receiving tongue 28, at which the base plate 5 also terminates. As already explained in more detail regarding the retaining element 5, the first webs 8, together with the base plate 5, or in this case with the receiving tongue 28, form the receptacle 29 for the other, or upper, visible profile 2. Due to the parallel first webs 8, the receptacle 29 provides improved retention of the other visible profile 2 on the retaining element 50.

[0042] It goes without saying that in facade system 1, according to the Figure 1 and 2 Instead of the retaining parts 5 or in addition to the retaining parts 5, also the retaining parts 50 according to the Figures 4 and 5 They can be used, which was not explained in detail.
