EP0005544B1 - Device for removably fixing a shelf to a column of a display stand - Google Patents

Abstract

A merchandise base, such as a shelf, is mounted on a supporting column by a device having pins or the like received in vertically spaced holes or recesses in the column. The pins are interconnected by a plate, and at least the upper pin has a radially enlarged head. Both pins interfit with a bracket on the base and the enlarged head secures the bracket against movement away from the column.

Description

The invention relates to devices of the type described in the preambles of claims 1, 2 and 9 for releasably anchoring a goods shelf to a recessed pillar of an interior decoration system, with a connecting plate which carries fastening elements engaging in the recesses on the back and on the front with a Support device is provided, and with a carrier disc or a carrier element for the storage of goods, which can be used in the supporting device with a selectable inclination secured by locking means about its longitudinal axis relative to the horizontal.

A comparable device is known from DE-A 2 501 349. The support device on the connection plate consists of a pair of vertically arranged pins. Either a vertical longitudinal groove or guide slots in connection with circular cutouts are formed in the support element as counter bearings, in which the pins can engage. During assembly, the merchandise base, which is provided with a carrier element at both ends, is only placed onto the pins from above to a limited extent. The inclination of the goods floor can be selected so that goods placed in the rear area can be made clearly visible in all cases.

If the merchandise floor is subjected to very high loads or exceeds a certain length, it tends to bend, with the result that axially acting forces are exerted on the connecting plate. These act in the upper area as tensile forces pointing away from the column, which, with sufficient size, can result in loosening or loosening of the mounting of the support element on the connection plate.

Devices of the type specified at the outset are proposed in the unpublished DE-A 2 739 147. The carrier element is designed as a carrier disk with a circular outline. It can be inserted into the support device at a selectable inclination secured by locking means about its longitudinal axis relative to the horizontal. The axial tensile forces that occur when the goods storage area is heavily loaded can also release the carrier disk from the support device. The inclination of the product base is adjustable to a greater extent than in the prior art according to DE-A 25 01 349.

The invention has for its object to design a device of the type mentioned in such a way that the possibility of choosing larger inclinations is retained, but a separation between the connecting plate and the carrier plate is still prevented when loading the goods shelf.

According to the invention, this object is achieved in that the carrier disc is a circular disc and the locking means consist of at least one pin on the support device and of several recesses on the circumference of the carrier disc for the appropriate reception of the pin (claim 1).

The axial tensile forces that occur when the goods shelf is loaded are absorbed by the pins of the connection plate, its fastening elements and the pillar of the interior system. A separation is prevented.

In an embodiment of the invention, the recesses can be designed as bores. If - as provided in a further embodiment of the invention - the recesses on the side facing the column are open and on the support device there is provided a cap which axially holds the carrier disc, the carrier disc can be produced particularly inexpensively from a toothed disc placed on a plate.

As a second solution to the problem it is provided according to the invention that the support device has a radial cap that holds the carrier disk axially (claim 2). The wrap prevents the splitting without affecting the possibility of choosing different inclinations. In an embodiment of this solution, it is provided that the cap is designed as a radially inwardly projecting rib and the carrier disk has a circumferential groove on its circumference, and further that the cap is designed as an outwardly tapering cone of the support device and the carrier disk is a has outwardly widening conical periphery. In another embodiment it is provided that the cap has a step that jumps inwards outwards and the carrier disk has a correspondingly graduated periphery.

In both proposed solutions, an embodiment of the invention consists in that the carrier disk is connected in the center via a spacer to a T-carrier embedded in the goods shelf, the spacer forming a groove with the T-carrier for engaging the union.

As a third solution to the problem, it is proposed according to the invention that the connection plate has a central, essentially circular opening, into which a plurality of teeth protrude radially inwards, and that the carrier element is designed as a T-shaped hooking hook protruding from the side wall of the goods shelf which the crossbar of the T forms a plate and has a width which is slightly less than the clear width of the central opening, and which at its end facing away from the goods shelf has a downwardly projecting hook behind the edge of the central opening and can be fixed between two teeth Has locking nose (claim 9).

This version is particularly advantageous in those cases where a fine level height adjustment position of the goods shelf on the pillar of the interior decoration system is not necessary.

So that the plate does not get caught in the recesses between the teeth when adjusting the inclination of the goods shelf, an inwardly bent spring element can be placed on each of the two opposite ends of the plate, which prevents the plate from snapping into the recesses.

The connecting plate 81 according to FIG. 1 has the outline of an inverted drop and has a pair of pins 82a, 82b extending from the rear, which can be inserted into recesses in a wooden column 71 (FIG. 13). From the front protrudes a semicircular and L-shaped wreath 83, the free leg 84 pointing into the interior of the semicircle extends parallel to the front surface of the connection plate 81 at a distance d to be explained. The base 85 of the ring 83 connected to the front side of the connecting plate 81 carries three teeth or pins 87, 88, 89 at the lowest point on the inside thereof in an arrangement symmetrical to the vertical. The teeth rise up from the bottom of the base 85, have a trapezoidal cross section and completely fill the inner width of the ring 83 except for a front section 26.

The carrier element 66 consists of a disc with external teeth 76, the spacing of which is selected such that the external teeth 76 fit smoothly between the teeth or pins 87, 88, 89 (FIGS. 1, 2) of the ring 83 and the teeth or pins in the Recessing space between the teeth 76 are appropriately recorded. The carrier disk 66 is fastened to the support bracket 67 via a spacer 68, which is designed as a T-rail in this example and supports the goods base 70. The thickness of the carrier plate 66 is substantially equal to the distance d between the leg 84 and the front side of the connecting plate 81 and the thickness of the spacer 68 is greater than the wall thickness of the leg 84. Therefore, the carrier plate 66 with the support angle 67 and product base 70 can be inserted into the collar 83 can be hooked in and fixed in any inclination about an axis passing through the center of the arc of a circle by engagement of the external teeth 76 with the teeth 87, 88, 89. The outer teeth 76 remain hidden behind a flange 28 which runs around the edge of the periphery of the carrier disk 66 facing the goods base 70 and which has the same height as the outer teeth and a somewhat smaller thickness than the width of the front section 26.

If the leg 84 is omitted in this embodiment, the result is a device that can be manufactured much cheaper compared to the arrangement described in DE-A-27 39 147, without losing the universality with respect to the selectable and adjustable angle of inclination. The carrier disk 66 can be a commercially available gear, for example, and the teeth 87, 88, 89 with the base 85 can also be produced very easily using prefabricated components.

With leg 84, this embodiment of the invention enables the axial fixation of the carrier disk 66 on the connecting plate 81 even when the product base 70 is subjected to high loads without impairing the choice of the inclination angle of the product base 70.

Instead of a continuous semicircular ring 83, one can possibly restrict oneself to three separate sections 90, 91, 92, which are arranged along a circular periphery and of which section 92 carries the teeth 87, 88, 89 as the lowest section without legs 84. The sections 90 and 91 could then be delimited at the dotted edges 90a and 91a a.

The section from FIG. 2 shown in FIG. 5 shows the use of an upwardly tapering mandrel or pin 80 instead of the tooth 88, which is arranged in the center of the base 85. Teeth 87 and 89 are omitted. Likewise, the leg 84 is missing, and only the angular sections 90, 91 are provided to prevent the carrier disk 66 from tilting. According to FIG. 6, the latter has no outer teeth on the smooth circumference, but is instead provided with bores 93 which allow the carrier disk 66 to be pushed onto the mandrel 80 in a selectable inclination of the product base 70. Otherwise, this embodiment of the invention corresponds to that shown in FIGS. 1-4.

In the embodiment of the invention according to FIGS. 7 to 11, the connection plate 81 has on its front side an upwardly open, polygonal recess 100 as a pan-shaped support device, the support element 66 consists of a circular disk with a polygonal outline and the connection plate is in one in the Column 71 inserted U-rail. The U-rail 94, which is embedded over the entire height of the column on the side pointing in the longitudinal direction of the goods base 70, has on its rear side a plurality of holes 95 arranged one above the other in a row with the same spacing, into which holes on the rear side of the connection plate 81 trained angle hooks can be hung. Since each angle hook 96 engages behind the lower edge of each hole 95 when the connection plate 81 is suspended, the suspended connection plate 81 is secured against axial movement in the U-rail 94. When using the connection plate 81 according to FIGS. 1 and 2, the same effect results if each pin 82a, 82b is provided with an undercut 130 on the lower peripheral section directly on the rear side of the connection plate 81.

At least from the vertical bearing surfaces 98, 99 of the recess 100, at a distance from the front of a continuous rear plate 97 on the connecting plate 81, ribs 57, 58 act as a union. The carrier disk 66 has a circumferential groove 59, in which the ribs 57, 58 engage.

A circumferential, radially projecting strip 56 is formed on the rear side of the carrier disk 66 by the circumferential groove, which engages behind the ribs 57, 58 at any angle after the carrier disk 66 has been inserted into the connecting plate 81. Since the strip 56 itself consists of several polygon-like sections, two opposite sections of the strip 56 engage behind the mutually opposite ribs 57, 58. In FIG. 8, two angular positions of the carrier disk 66 are shown by dash-dotted lines indicating the contact angle. In one position the support angle is horizontal, in the second position shown the support angle inserted into a front recess 55 of the carrier disk 66 tilts downward to the right. In both positions, different, opposite sections of the strip 56 on the carrier disk 66 engage behind the ribs 57, 58.

10 and 11, polygon surfaces 98, 99 each have an inwardly projecting step 102, 104 on their section pointing away from the front of the back plate 97, which narrow the opening of the connection plate 81. Each of the two steps 102, 104 merges into the rear base section 106, 107 via an inclined surface 108. Although it is sufficient for the purposes of the invention if two opposite polygon surfaces are each provided with a step 102, 104, each of the polygon surfaces is equipped with a corresponding step in the illustration.

According to FIG. 11, the carrier disk 66 has a front polygon section 110 with a smaller diameter, to which an edge 101 which projects radially over an oblique transition surface 105 is connected to the rear. The edge 101 has an outer diameter that is slightly smaller than the inside diameter of the connecting plate 81 measured between the base sections 106, 107, while the radial extent of the front section 110 of the carrier disk 66 is smaller than the inside diameter between the steps 102, 104 of the Sub-base.

In use, the edge 101 engages behind the steps 102, 104, the inclined transition surface 105 abutting the inclined surfaces 108. This embodiment also allows the carrier disk to be used at any angle specified by the polygon surfaces. Furthermore, the space available between opposing columns 71 is used for the goods storage 70.

In the modification, which can be seen in vertical section in FIG. 9, the axial locking of the carrier disk 66 is achieved by means of wedge surfaces. The polygonal surfaces rise uniformly outwards, so that the inclined surfaces 108 as conical surfaces 117 extend over the entire depth of the polygonal surfaces. Correspondingly, the carrier disk is designed as a polygon cone with polygon surfaces 115 extending radially inwards.

The further embodiment of the invention shown in FIGS. 12 to 14 is expedient especially for load-bearing woods without the stabilizing rail. According to FIGS. 12 and 13, the connection plate consists of a rosette 112 which is screwed into a bore 116 of the column 71 with a rear external thread ring 114. The rosette also has a front tooth plate, in the central opening 120 of which a plurality of teeth 122 protrude inwards.

The support element is placed as a hook 124 butt on the support bracket 67. Its lower end pointing away from the support angle 67 is extended downwards to a nose 126. On the upper edge, the hook has a plate 128 which extends at least such a distance from the support angle 67 that its edge pointing away from the latter lies over the front edge of the nose 126. The length of the plate 128 in the direction of the support angle 67 is slightly less than the distance between the crowns of the two opposite teeth 122a, 122b. In plan view of the support bracket 67, the carrier element with plate 128 thus forms a T, which is hatched in FIG. 12.

In order to further secure the carrier element in the opening of the rosette-shaped connecting plate 112, a spring element 123, 125 can be riveted to the top of the plate 128 on both opposite sides, which spring element extends inwards at the free end (FIG. 12). As a result, as much lateral play as possible of the carrier element between the teeth 122a, 122b is pressed down and prevents when the carrier element is inserted in the tilted position, that is to say approximately between the teeth 122c, 122d, the plate 128 of the carrier element hooks between the teeth. 14, the spring elements 123 and 125 are omitted for a better overview.

For use, the product base 70 is suspended in the connection plate with the support element fastened transversely to the support angle 67, so that the lug 126 engages in the bore 116 behind the connection plate 112. The side edges of the plate 128 then lie against the opposing teeth 122a, 122b and secure the goods base against tipping about the longitudinal axis. If an inclination of the product base 70 is desired, the carrier element can be suspended between other teeth, for example the neighboring teeth 122c, 122d.
