Description

[0001] Device for attaching an object to a wall.

[0002] The invention relates to a device for attaching an object to a wall and in particular a partition wall for shopfitting applications according to the preamble of claim 1. State of the art:

[0003] Shopfitting refers to the furnishing of commercial spaces, particularly retail businesses, with furniture suitable for sales purposes. In particular, walls are fitted with shelving systems for product presentation. For example, VITRA offers a shopfitting system with so-called single-point support systems, in which point-shaped elements are attached to a partition wall and can be fitted with brackets or supports as needed. These brackets or supports then serve to hold various storage systems, such as glass shelves or other merchandise displays, or simply as hanging fixtures for display merchandise.

[0004] From DE 10 2013 006 282 A1, a plug-in device for a product presentation arrangement is known, in which a socket is attached to a supporting structure, in particular a partition wall, wherein a through-hole through the wall enables the socket to be received and its corresponding fastening to the wall. A plug-in device is then inserted into the socket as a console when required.

[0005] A similar device is known from DE 102 07 474 A1, in which a supporting structure is also provided as a wall with a through-hole, which serves to receive a plug-in socket in which in turn a plug-in part is optionally received as a product console.

[0006] Conventional single-point support systems generally use a through-hole through the supporting structure or partition wall, resulting in a potentially disruptive overall appearance of an otherwise uniform wall structure when no inserts or brackets are used. If the wall has a distinctive texture, color, or ornamental design, such circular holes or socket-shaped inserts are likely to detract from the overall appearance of the wall.

[0007] The object of the invention is therefore to provide a device for fastening an object by means of so-called point-shaped elements, which, when the console is not used, allow only a minor interruption of the overall appearance of the wall structure. Solution to the problem:

[0008] Starting from a device for fastening an object according to the features of the preamble of claim 1, the problem is solved by the characterizing features of claim 1.

[0009] The dependent claims specify advantageous and appropriate further developments of the subject matter according to claim 1. Core of the invention:

[0010] The invention is based on the core idea of ​​using a so-called single-point support system element on a supporting structure, and in particular a partition wall for shopfitting applications, which does not require a through-hole through the wall and consequently causes only minimal disruption to the surface structure of the partition wall. According to the invention, this is achieved by designing a cup-shaped bushing for the point-like element as a metal ring, which comprises only circular segment-shaped cylindrical wall segments or tongues. These are guided through the wall by means of corresponding segment-shaped wall openings and are fixed on the back of the wall by means of a screw connection. This means that the wall surface does not include a cylindrical through-hole for receiving a bushing, but only two or three partially cylindrical wall segments as through-openings.This ensures that the inner area of ​​the point-shaped element or metal ring is not cylindrically recessed, but rather retains its structure and surface almost completely. This results in a particularly harmonious appearance of the entire wall, especially when no brackets are used.

[0011] A perforation-like, circular segment-like opening in the form of slots is particularly advantageous for inserting the circular segment-shaped cup-like wall parts or tongues through the wall without destroying the inner area of ​​the wall.

[0012] A rearward support of the tongues of a spacer tire between the arc-shaped wall segments is advantageous as an effective support for a screw connection.

[0013] Furthermore, it is advantageous to form, for example, a metal ring as a point-like element of a concave, circular line of contact oriented towards the wall, in order to enable only a small, linear contact surface of the metal ring on the wall surface.

[0014] Another advantage is that the point-shaped element, as a metal ring, forms a pot-shaped cylindrical interior that does not cover the wall surface structure.

[0015] Another advantage is that the metal ring has a radially inward-facing edge, which serves as an undercut for mounting a mounting flange for a wall bracket.

[0016] A particularly advantageous feature is the creation of recesses within the wall and within the mounting flange for a wall bracket, designed to accommodate primary and secondary induction coils for electrical connection of the bracket. For this purpose, the wall penetrations include electrical conduits for electrifying the brackets.

[0017] The design of the wall as a decorative wall, for example with a fabric covering or wallpaper or as a color print, is particularly advantageous in that a designer wall is formed which is only slightly interrupted by the point-shaped elements of the single-point support system, whereby the interior of the point-shaped elements or the metal ring also shows the complete wall structure. Drawings:

[0018] The invention is illustrated in the drawings and explained in more detail in the following description.

[0019] They show: Fig. 1: A wall representation for a shopfitting application with ring-shaped point-like elements as a fastening system, or single-point support system, Fig. 2: A complete cross-sectional view of the device according to the invention with a point-shaped element integrated into a partition wall, including fastening and attached adapter, Fig. 3: A single representation of the point-shaped element as a metal ring in the facing wall with rear support of the tongues and fastening device, Fig. 4: a milling pattern for the milling work in the partition wall, Fig. 5: a section of the point-shaped element designed as a metal ring with a concave arrangement, Fig. 6: a front view of the point-shaped element designed as a metal ring with dashed back milling and cove, Fig. 7: a rear view of the spacer ring and the through slots for the cylindrical wall segments or tongues, with electrical connection, Fig. 8: A rear view of the point-shaped element with cable routing for power transmission. Description of the exemplary embodiment:

[0020] The Fig. Figure 1 shows a view of a supporting structure, a wall, a partition wall 1, hereinafter referred to as "partition wall", wherein the partition wall is covered with a covering of fabric or wallpaper or paint 2, which is decorated with ornaments 3. The in the Fig. The depicted partition wall comprises 6 so-called point-shaped elements 4, which are also designed as metal rings. From the Fig. Figure 1 clearly shows that the surface structure of the facing wall is continued in the inner circle of the metal ring 4, so that the metal ring has no central recess. Therefore, the overall appearance of the surface is not, or only minimally, disturbed by the metal rings 4. The metal rings shown in Fig. 1 do not yet have any installed support elements or brackets.

[0021] The in Fig. The section through part of the single-point support system shown in Figure 2 is further explained in the following figures.

[0022] The Fig. Figure 2 shows the partition wall 1 in cross-sectional view with a cover layer 2 applied, for example, as fabric, wallpaper, or paint. The point-like element 4 is designed as a metal ring 5, which rests on the fabric layer 2. The metal ring is designed as a cup-shaped socket 6 with three cylindrical wall segments or tongues 7 that project through corresponding segment-like wall openings 8. As can be seen from the milling pattern in Fig. As can be seen in Figure 4, three through-millings 9, 9', 9'' are produced at a rotational angle of 120 degrees as wall penetrations 8 through the entire wall 1 of the front wall, through which the corresponding tongues 7 of the cup-shaped bushing 6 are guided. The cylindrical wall segments 7 thus only encompass an angular range of Alpha approximately equal to 20 degrees with a triple arrangement on the circumference 10. In the upper half of the figure of Fig. Figure 2 therefore shows only a concealed cylindrical wall segment 7 in cross-sectional view, which is formed by a corresponding through-milling 9, 9', 9''. The cylindrical wall segment 7 has a threaded structure 11 on its outer circumference to secure the point-shaped element 4.

[0023] The one in Fig. The metal ring 5 of the point-shaped element 4 shown in Figure 2 has a circumferential, radially inwardly directed rim, which serves as an undercut for holding a cup-shaped mounting flange 13 or a bracket base element 13 of a wall bracket or a wall console 14. The cup-shaped mounting flange 13 has a bonded or pressed-in cover 15 on its end face.

[0024] Out of Fig. 3 are details from Fig. 2. Identical parts are numbered with the same reference numerals. The cylindrical wall segments or tongues 7 projecting through the through-millings 8, 9 of the facing wall 1 are fixed on the back side 36 of the wall with a threaded nut 16. Since the cylindrical wall segments 7 only extend over a segment area, a spacer 17 is inserted on the back side 36 on the inner wall 37 of the cylindrical wall segments 7, which enables radial support of the cylindrical wall segments 7 when the threaded nut 16 is applied.

[0025] The Fig. Figure 5 shows a detail of the metal ring 5 which is placed on the fabric or wallpaper 2. The contact surface on the surface 35 of the wall 2 is designed with a concave groove 18, so that the contact surface is formed by only two rings 19, 19'. This ensures that, for example, the fabric beneath the metal ring does not shift, thus guaranteeing a perfectly smooth surface even when the metal ring is tightened.

[0026] The Fig. Figure 6 shows another view of the metal ring 5 with an indicated back milling 20, which serves to engage the cup-shaped mounting flange 13. According to Fig. 2 The lower area of ​​the back milling on the metal ring 5 is designed such that the outer edge 21 of the mounting flange 13 rests inside the metal ring 5 in the back milling, while in the upper area of ​​the Fig. 2 a clearance 22 of the undercut 20 is created in the metal ring 5, which allows the cup-shaped mounting flange 13 to be guided upwards in order to lift it out of the undercut in the lower area. This is achieved by the asymmetrical representation of the undercut 20 in Fig. Figure 6 shows the recess 20 with a wide upper section and a very narrow lower section. The lower recess 20, and thus the lower edge 21', can be omitted if necessary. Alternatively, the recess in the metal ring 5 can be omitted entirely or partially, provided that the mounting flange 13 is held or trapped in the metal ring.

[0027] For the electrification of the point-shaped element 4 or the metal ring 5, a first cavity 23 is provided on the primary side 25 within the outer wall 1, and a second cavity 24 on the secondary side 26 within the cup-shaped mounting flange 13. The first cavity 23 serves to accommodate a primary coil, the second cavity 24 to accommodate a secondary coil for an inductive current supply from the primary side 25 to the secondary side 26 of the system.

[0028] In the Fig. 7 and Fig. Figure 8 shows the respective cable routing for supplying power to the primary coil in cavity 23 and the secondary coil in cavity 24. The primary cable is designated with reference numeral 27. Fig. Figure 8 shows a distributor 29 for the power supply of the secondary cables leading to the through-millings 9, with the cable guide 31 running along the threaded sections 11 through the material. Contacts 32 in Fig. 8 are used for power transmission. Alternatively, contactless inductive power transmission is possible. In Fig. Figure 7 additionally shows the spacer ring 17 as a support and pressure ring 17.

[0029] The representation in Fig. Figure 2 shows the mounting flange 13, which is designed as a suspension bracket 14 and which is equipped with tubular additional parts 33 that are fastened with a grub screw 34.

[0030] The invention is not limited to the illustrated and described embodiment. Rather, it also encompasses all embodiments within the scope of the patent claims. Alternatively, instead of the cylindrical wall segment or tongues, two or three threaded rods with nuts on the back can be used.
