Description

The present invention relates to a mounting element for mounting rails, in particular for suspended ceilings or the like, with a base portion formed at least partially planar, which has a coupling portion designed for coupling with a mounting rail.

Such mounting elements are used for example for connecting two mounting rails together, for connecting a mounting rail with another component or for hanging a mounting rail to the ceiling of a room. In particular, mounting elements of the type mentioned can be quick-release hangers, angle anchors, cross-quick connectors or the like. In the case of a Schnellspannabhängers the base part can be adjustably attached to a fixing part, which in turn is designed for attachment to the associated ceiling. A flat design of the base element allows for easy and cost-effective production and easy storage in stacks. The mounting rail can be coupled in various ways with the base part. For example, The base part can be hooked to the mounting rail.

There is a need to increase the stability of mounting elements of the type mentioned and in particular the strength of the coupling between the base part and the mounting rail - with mounted and loaded mounting rail and mounting element - in the respective loading direction to increase. The load direction is defined at least predominantly by the weight of the mounted components and thus usually runs perpendicular to the ground. In principle, the increased stability could be achieved in that the base part is carried out in a complex construction, for example by joining several individual components or by a multi-layered design. However, such solutions are associated with increased effort and corresponding costs.

It is an object of the present invention to provide a mounting element of the type mentioned, which ensures increased stability with a simple and cost-effective manufacturability.

The object is achieved by a mounting element having the features of claim 1.

According to the invention, in the region of the coupling portion, a first areal piece of the base part is bent over a second areal piece along a bending edge. By means of the bent-over area piece, the strength of the base part in the region of the coupling portion and thus the stability of the mounting element can be increased for a given material thickness. The advantage here is that a bending process is particularly simple and inexpensive to carry out. The bent surface piece thus forms a particularly easy to manufacture reinforcing or stiffening element of the base part.

Further developments of the invention are specified in the dependent claims, the description and the accompanying drawings.

Preferably, the first and second sheet pieces cooperate at a common support point to support the support rail in a loading direction. In particular, can be increased by the presence of both surface pieces at the common support point, the support surface for the support rail and thus the load capacity of the support rail can be increased.

According to an advantageous embodiment of the invention, the bent-over first surface piece forms an at least partially material reinforcement of the coupling portion. In particular, the material reinforcement can form the common support point. As a result, the coupling section, which is particularly stressed in the case of load, can be made significantly more stable in a simple manner, in particular in the area of the loaded support point.

Preferably, the base part is at least partially T-shaped or anchor-shaped with a central support portion and extending transversely extending therefrom side wings forming the coupling portion, wherein the material reinforcement at least partially along a respective outgoing from the central support portion edge of the side wings extends. In particular, in this case the first surface piece is bent relative to the second surface piece such that the flexural rigidity of the side wings is increased at least in the transverse direction to the central support portion. As a result, bending of the side wings is reliably prevented, in particular with an oblique loading of the mounting element.

This is also achieved by a further advantageous embodiment of the invention, according to which the first surface piece in relation to the bent second surface piece, that the flexural rigidity of the coupling portion is increased at least transversely to a loading direction.

The bending edge extends according to an embodiment of the invention in a straight line, in particular along a loading direction or transversely to a loading direction. According to one embodiment, a bending edge extending transversely to a loading direction can be arranged such that the mounting rail rests directly on the bending edge in the assembled state. As a result, a particularly robust construction is achieved.

The first patch may form an outer edge of the base. For example, the first surface piece may be a folded edge strip of the base part. The bending edge may also form an outer edge of the base part, so that it may be e.g. can come into direct contact with a hinged mounting rail.

According to a further embodiment of the invention, the first surface piece is bent relative to the second surface piece by 180 °, in particular such that results in a double-layered area. The first surface piece is thus completely folded over during the production of the base part along the bending edge. The support rail can be supported in such a configuration on both surface pieces alike, essentially at one and the same support point, so that so doubles the support surface over a construction with only one surface piece.

To further increase the stability, the first surface piece, preferably by at least one rivetless connection, be attached to the second surface piece.

According to a further embodiment of the invention, the first surface piece opposite the second surface piece by between about 80 ° and 100 °, in particular by about 90 °, bent. For example, an edge portion of a flat base part may be flanged or folded over at least in sections so as to produce an L-shaped profile structure in the region of the coupling portion, which increases the stability of the coupling and increases the contact surface.

The first surface piece may further comprise a bulge formed for a clamping engagement with the support rail. As a result, for example, a mounting rail suspended or hooked into the base part can be held more securely. The bulge may in particular be designed such that the base part jammed when inserted into a profile-like mounting rail with this. An accidental pulling out of the base part of the mounting rail is prevented by such a deadlock.

The bulge may be formed in particular as edge-side upstand of the first surface piece. Such Aufkantung is particularly easy to produce, for example, by an edge portion of the folded sheet is partially bent back by a small amount.

Preferably, the base part is made of a metal sheet. This allows a particularly simple and inexpensive production.

According to one embodiment of the invention, the first sheet is bent by a deep-drawing process to allow quick and easy production. In addition, the deep drawing causes a work hardening effect. Since the bending takes place in the region of the coupling portion of the mounting element, the deep-drawing Stability and thus significantly increases the carrying capacity of the mounting element.

The base part may also be designed as a stamped part, wherein the first surface piece is a so-called waste piece of a punching operation. A waste piece is understood to be a surface area of the starting material which, after the punching process, is arranged at a location which lies outside the outer contour of the base part and thus would actually have to be separated off and discarded. According to the embodiment of the invention, such a surface piece is advantageously used to increase the stability of the arrangement. That is, it is reduced by the bending of the waste piece in the region of the coupling portion of the material scrap and at the same time increases the stability of the mounting member.

The base part may further comprise at least one reinforcing bead, which tapers to the bending edge. As a result, a further stiffening and increase in strength can be achieved.

According to a further embodiment of the invention, the coupling portion comprises two hook-like side wings which extend away from a central support portion. A base part designed in this way can serve, in particular, to support a support rail with a U-shaped cross section and hook-like bent edges. On each side wing may be a bent surface piece, so as to increase the stability of the coupling, whereas the central support portion may be formed as a simple surface piece without bent portions.

The first surface piece and / or the second surface piece may have a reinforcing bead, which extends in particular in a loading direction. This can further increase the stability of the construction.

A method for producing a mounting element of the type described above is characterized in that, to form the coupling portion, a first surface portion of the base portion is bent over a second surface portion along a bending edge. In particular, the first surface piece can be bent by a deep drawing process.

Fig. 1 shows a known mounting element, which is designed as a quick release hanger with a base part 11 and a fixed to the base part 11 connecting part 13. The quick release hanger can be attached to the ceiling of a room via a rod-shaped attachment part 15.

The base part 11 is formed flat and has a central support portion 20, extending from the lower end of two hook-shaped side wings 21, which form a coupling portion 18 for coupling the base part 11 with a profile-like support rail, not shown. Such a support rail can be hooked to the side wings 21, so that the support rail is supported at a support point 17 of the side wings 21. On the support rail more transverse support rails may be formed, which are formed for example for supporting panels for suspended ceilings. The base part 11 could also have a plurality of coupling sections and thus be used as a connecting element, for example as a cross-quick connector, between a plurality of mounting rails.

When mounted Schnellspannabhänger the base member 11 and the connecting part 13 are charged by the weight of the support rail and the elements supported by this in a loading direction B.

The Fig. 2 and 3 show a mounting member according to a first embodiment of the invention, which is used as a base part 11 of a Schnellspannhängers similar to in Fig. 1 shown quick release hanger is formed. To fix the quick release suspension to the ceiling, the base 11 may be similar to the system shown in FIG Fig. 1 be coupled for example with a connecting part and a rod-shaped fastening part. The base part 11 is made of a simple metal sheet and formed substantially flat, wherein reinforcing beads 22 are embossed into the metal sheet for stiffening and in the region of the central support portion 20, a folded-edge 24 is provided. On the side wings 21, in each case a first surface piece 25a is bent along a horizontally extending, rectilinear bending edge 23 by 180 ° with respect to a remaining second surface piece 25b, so that both surface pieces 25a, 25b abut one another in the region of the coupling portion 18 and thus form a double-layered region 27 ,

The two surface pieces 25a, 25b are substantially against each other over the entire surface, wherein, however, a reinforcing bead 22 extends through the double-layered region 27 such that a corresponding cavity 28 is formed between the surface pieces 25a, 25b. By means of, for example, by a pressure-joining method such as clinching, clamping, pressing or crimping produced nietlosen connections 29, the first surface portion 25a is additionally attached to the second surface portion 25b. How out Fig. 3 shows, in the mounted state of the device, a folded-edge 30 of a profile-like support rail 31 is supported on the support point 17 of the coupling portion 18 from. Due to the double-layered area 27, the bearing surface is for the hooked DIN rail 31 is twice as large as in the quick release hanger according to Fig. 1 ,

The bent-over first surface piece 25a is a so-called piece of waste which, when punching out the hook shape of the side portions 21, remains as scrap and would have been conventionally cut off.

In the Fig. 4 to 8 a mounting element in the form of a quick release according to a second embodiment of the invention is shown, wherein like or equivalent components are denoted by the same reference numerals as in the first embodiment according to FIG Fig. 2 and 3 , In contrast to the first embodiment, in the second embodiment, the bending edge 23 extends vertically instead of horizontally, that is, in the loading direction B. That is, during production of the base part 11, an outer first surface piece 25a is bent inwardly on each side wing 21. Furthermore, a reinforcing bead 32 which is spatially limited to the double-layered region 27 is provided, which extends in the loading direction B. Also in this embodiment, on the one hand, an enlarged support surface for the support rail 30 and, on the other hand, increased rigidity of the side sections 21 is achieved.

The Fig. 9 to 11 show a mounting member according to a third embodiment of the invention, in turn, the same or equivalent components are denoted by the same reference numerals as in the embodiments described above. In contrast to the first two embodiments, in the third embodiment, the first surface piece 25a is not bent by 180 °, but by 90 °. The first patch 25a forms a narrow edge strip which extends both along the central support section 20 and along the top the side wing 21 extends, whereby an L-shaped profile structure is formed. In this embodiment, the support surface for the mounting rail 31 (FIG. Fig. 10 ) be further increased, since the bent surface piece 25a over the entire surface of the support is used. However, as in the first two embodiments, both face pieces 25a, 25b cooperate with the support point 17 to support the support rail 31. The bending edge 23 extends in the base part 11 of the third embodiment is not straight, but curved. As in particular from Fig. 11 As can be seen, a reinforcing bead 22 of the base part 11 is pointed to the bending edge 23 and ends there, whereby a particularly high stability at the support point 17 can be achieved.

FIGS. 12 and 13 show a fourth embodiment of the invention, which is designed similar to the third embodiment according to Fig. 9 to 11 , The base part 11 is embodied here as a deep-drawn sheet-metal component, the edge strip being folded over in the context of deep-drawing, which forms the bent-over surface piece 25a, extending along the entire longitudinal sides of the base part 11.

At the in FIGS. 14 and 15 illustrated fifth embodiment of the invention is provided as a first surface piece 25a also bent by 90 ° relative to the second surface portion 25b edge strip which extends along the entire longitudinal sides of the base part 11. The bent surface piece 25a is here folded in the corner region of the coupling portion 18 to form a pointing against the loading direction B bulge 35 in the manner of a table cloth fold. The base member 11 may be deep drawn as in the fourth embodiment, but it may be made by simply bending while avoiding a deep drawing process. Due to the material surplus in corner areas resulting folds or bulges are usually undesirable. However, the bulge 35 in the region of the coupling portion 18 may be advantageous in the present application, as this can be a thinning of the corner occurring thinning of the material can be prevented, which could otherwise just weaken the support point 17. In addition, the bulge 35 can improve the power transmission between the mounting member and a mounting rail. In particular, it allows the bulge 35, the base member 11 along a direction of insertion S in a mounting rail, but prevents a shift against the insertion direction S, since the base member 11 thereby jammed in the support rail and thus secured against accidental withdrawal.

Fig. 16 shows a mounting member according to a sixth embodiment of the invention. The mounting element here is a cross-fast connector, which is suitable for connecting two crossed mounting rails. The base part 11 'has a U-shaped cross section and comprises two central support sections 20 which project at right angles from a bridge section 37. Both support sections 20 have two side wings 21, as in the embodiments described above, so that two separate coupling sections 18 are ultimately formed on the base part 11 'for engagement with a mounting rail. The U-shaped base part 11 'can be hooked to the coupling sections 18 in a mounting rail in such a way that it encompasses a further crossed mounting rail, so that both mounting rails are connected to one another. In a similar manner as in the first embodiment according to Fig. 2 and 3 At the existing side wings 21, respective first surface pieces 25a are bent through 180 ° along horizontally extending, rectilinear bending edges 23 relative to remaining second surface pieces 25b, so that the respective surface pieces 25a, 25b abut one another in the region of the coupling sections 18 and thus form double-layered regions 27.

Overall, by bending a first surface piece 25a relative to a second surface piece 25b, a reduction in stress in the region of the coupling portion 18 can be achieved, whereby a tearing of the mounting rail from the mounting element can be avoided with little effort.
