Description

[0001] The invention relates to a device for fastening elongated profile rails, in particular LED profiles or displays, to a rod- or bracket-shaped support element attached to a holding device, which has a front end for attachment.

[0002] In retail outlets such as hardware stores and supermarkets, rod- or U-shaped support elements are frequently used to hold numerous products. These elements are attached to vertically arranged holding devices. These devices are often designed as perforated plates into which the support elements can be inserted from the back. The support elements serve not only to hold the product packaging placed on them but also for product labeling. The rod-shaped support elements, which typically have an upward-sloping front end, are also called single hooks, while the U-shaped support elements, which typically have an upward-sloping, curved front end, are also called double hooks.

[0003] From DE 85 14 246 U1, a device for attaching a holder for information carriers, designed as a profile rail, to a perforated plate is known. This device comprises a base body that can be connected to a perforated plate and has a support element, a connecting element at the end of the support element facing away from the base body, and a profile rail designed to be connected to the connecting element of the support element. The connecting element is, for example, firmly connected to the rod- or U-shaped support element by welding, which is complex to manufacture. Furthermore, due to the shape of the connecting element, the entire device is only suitable for attaching a holder of a complementary design.

[0004] The object of the invention is to propose a universally applicable solution for fastening elongated profile rails to rod- or stirrup-shaped support elements.

[0005] This problem is solved according to the invention in a device of the type described above by a clamping element with at least one clip-shaped clamping piece for clamping to the front end of the support element, wherein the clamping element has a connecting element on a side forming the front in the mounting position for a form-fit and / or force-fit connection with the back of the profile rail.

[0006] A device with a clamping element is proposed, which is detachably clipped onto a support element, thus eliminating the need to modify the support element itself. The clamping element's connecting element is designed to match the geometric shape of the profile rail being attached. This allows the use of standardized support elements; only the device itself needs to be designed to be complementary to the profile rail in the connection area. Typically, two devices are used to attach an elongated profile rail, mounted to adjacent support elements. If the profile rail is an LED profile, lighting can be easily achieved using two devices, two support elements, and one LED profile.

[0007] In a preferred embodiment, the connecting element is designed as a web for engaging in a fastening groove of the profile rail. The web is preferably designed to be complementary to the fastening groove.

[0008] It can be advantageously designed so that the web projects beyond the clamping element on one side. This projecting area can serve to accommodate a fastening screw, which can be an expansion screw that presses the projecting area against the walls of the fastening groove.

[0009] To facilitate easy attachment of the device to a U-shaped support element, it is preferably provided that the at least one clamping piece is designed for external clamping to the front end of the support element.

[0010] To ensure a particularly stable connection between a U-shaped support element and the device, the clamping element is provided to have at least three arcuately arranged clip-shaped clamping pieces.

[0011] For attachment to the front end of a rod-shaped support element, the clamping element has only one clamping piece for lateral clamping.

[0012] The clamping element is preferably made in one piece and consists of plastic.

[0013] The invention also relates to a system with an elongated profile rail, in particular an LED profile or display, two rod- or U-shaped support elements, and two devices as described above, wherein the profile rail is connected to a support element at each of its two end regions via a device. With such a system, it is possible in a particularly simple manner to attach LED profiles for lighting or the like to mounting devices (e.g., perforated plates) equipped with rod- or U-shaped support elements, thereby significantly improving product presentation.

[0014] The invention is explained in more detail below with reference to the drawing. This shows in Fig. 1 a perspective view of a first device, Fig. 2 a second perspective view of the device, Fig. 3 a third perspective view of the device, Fig. 4 a top view of the device, Fig. 5 a view from the right Fig. 4, Fig. 6 a perspective view of the assembled device, Fig. 7 a side view of the assembled device, Fig. 8 a perspective view of a profile rail with two devices, Fig. 9 a perspective view of a profile rail with two devices and two support elements on two perforated plates, Fig. 10 a perspective view of a second device, Fig. 11 a second perspective view of the second device, Fig. 12 a top view of the second device and in Fig. 13 a view from the right Fig. 12.

[0015] A first device for fastening an elongated profile rail 1, in particular an LED profile or a display, to a stirrup-shaped support element 3 attached to a perforated plate 2 designed as a holding device, which has a front arcuate end 4, is generally designated by 5.

[0016] The device 5 comprises a preferably one-piece clamping element 6 made of plastic with a connecting element designed as a beam-shaped web 7 for connection with a fastening groove 8 on the back of the profile rail 1. If the back of the profile rail 1 has a different geometric design, the web 7 is designed accordingly in a complementary manner to enable a positive and / or force-fit connection of the clamping element 6 with the profile rail 1.

[0017] The clamping element 6 extends laterally from the beam-shaped web 7 into a U-shaped section 9 with a U-shaped web 9a and two U-shaped legs 9b. The U-shaped web 9a is inclined at an acute angle α relative to the beam-shaped web 7, so that the profile rail 1 is inclined in the installed position. In the installed position, the beam-shaped web 7 forms the front face of the clamping element 6 and preferably projects beyond the U-shaped web 9a of the clamping element 6 on one side; this end section is designated 7a. This projecting end section 7a serves to accommodate a fastening screw.

[0018] The clamping element 6 can also be installed at head height or above, or in reverse, to achieve a downward tilt of the profile rail 1.

[0019] On the inside of the U-shaped web 9a and the two U-shaped legs 9b, a clip-shaped clamping element 10 is formed for clamping onto the front end 4 of the U-shaped support element 3. The three clip-shaped clamping elements 10 are thus arranged in an arc and designed for clamping onto the outside of the front end 4 of the U-shaped support element 3.

[0020] Profile rail 1 can be an LED profile, whereby in Fig. 7 and Fig. 8 a power cable is indicated 11.

[0021] The respective U-shaped support element 3 is typically attached to a perforated plate 2 by inserting its open, preferably angled, U-shaped ends 12 into holes in the perforated plate 2 and pivoting them. To attach the elongated profile rail 1, a device 1 is attached to the respective mounting end 4 of each of two adjacent support elements 3 from the outside until the clip-shaped clamping pieces 10 on the mounting end 4 are engaged. The profile rail 1, with its mounting groove 8 at both ends, is then attached or slid onto the beam-shaped web 8 of both devices 1. If the profile rail 1 is an LED profile, the power cable 11 is subsequently connected to a power source.

[0022] In the Fig. 10, Fig. 11, Fig. 12 to Fig.Figure 13 shows a second device for fastening an elongated profile rail 1, in particular an LED profile or a display, and is also designated by reference numeral 5. Parts corresponding to the first device 5 are designated by the same reference numerals.

[0023] The second device 5 serves to attach the profile rail 1 to a rod-shaped support element, which has a front rod-shaped end for attachment. This support element is not shown in the drawing. It can also be arranged on a holding device designed as a perforated plate, e.g., suspended from it.

[0024] The second device 5 also has a preferably one-piece clamping element 6 made of plastic with a connecting element designed as a beam-shaped web 7 for connection with a fastening groove 8 on the back of the profile rail 1. If the back of the profile rail 1 has a different geometric design, the beam-shaped web 7 is designed accordingly in a complementary manner to enable a positive and / or force-fit connection of the clamping element 6 with the profile rail 1.

[0025] The clamping element 6 extends laterally from the beam-shaped web 7 into an L-shaped section 13 with an L-leg 13a. The L-shaped section 13 is inclined at an acute angle α relative to the beam-shaped web 7, so that the profile rail 1 is inclined in the installed position. In the installed position, the beam-shaped web 7 forms the front face of the clamping element 6 and preferably projects beyond the L-shaped section 13 of the clamping element 6 on one side; this end section is designated 7a. This projecting end section 7a serves to accommodate a fastening screw.

[0026] A clip-shaped clamping element 10 is formed on one side of the L-shaped leg 13a for clamping onto the front rod-shaped end of the rod-shaped support element. The clip-shaped clamping element 10 is designed for lateral clamping onto the front rod-shaped end of the support element.

[0027] Of course, the invention is not limited to the illustrated embodiments. Further embodiments are possible without departing from the basic concept. For example, the holding device can be designed differently than a perforated plate 2, with the support elements 3 then adapted to the holding device in a known manner.
