Abstract

Goods are displayed e.g. in shops or exhibitions on a rack having a frame structure (1) with side supports (12) for panels (2), the slope of which can be varied between horizontal and vertical positions and can be retained in the chosen position, allowing goods to be put on them or suspended from them. Several panels arranged one above the other form a rack division, the side supports being positioned horizontally like ladder rungs on either side of the division in pairs. Preferably, the panels are fixed with male fitting parts (3) connecting to female fitting parts on the supports in the rear portion of the panels.

Description

Field of application of the invention

The invention relates to a shelf with side supports which are attached to the adjustable shelves and a fitting for this, the shelves of the presentation serve goods. Board-like vertical supports come as supports, Horizontal brackets or support rods are considered. The fitting consists of a bearing - this is on the side support - and one on the side of the shelf fixed tooth lock washer.

For the presentation of goods in shops or at exhibitions be tables, showcases, stands or on back walls mountable carrier used. Another way is the goods to be presented on a shelf with a variety used trays. It is desired Were lying horizontally and inclined towards the customer to be able to perform. Such shelves must have the system of a modular system in many variations depending on the intended use Can be adapted ad hoc if possible without major installation effort be. Further requirements are placed on the load capacity of the individual trays and the stability of the whole Shelf structure placed. Last but not least, plays an appealing one Design matters at the lowest possible cost. A such a shelf, which consists of several, independently of each other there are adjustable and adjustable trays, as well as a Associated fitting for hanging and tilt adjustment the shelves are the subject of the present invention.

State of the art

A shelf is known from DE-A-31 19 207, for example, which consists of two spaced to be attached to a rear wall There is vertical support, which is a grid of holes have, in the mounting rails for receiving trays are attachable. This shelf is always present a supporting back wall and the shelves are not adjustable in their inclination, so that little open up creative possibilities. In US-A-4,919 A similar shelf is shown in 282, where the shelves are are adjustable in height but not in inclination.

GB-A-2 228 185 discloses a shelf with an incline adjustable shelves, two parallel, vertical grid rails and shelf consoles with step-shaped serrated hooks are provided. Hereby you can put the trays in different inclinations hang the grid rails. This rack structure needed the relatively strong and not very decorative grid rails. Furthermore, the selectable angle of inclination is a few Limited positions. A shelf emerges from US-A-3 921 539 with adjustable shelves, where also two Grid rails are available. The adjustment in the inclination is by means of fittings attached to the side of the shelves realized that pushed onto the grid rails are and can intervene in several inclination positions. The shelves that can be tilted in this way are for presentation suitable for lying, but not for hanging goods.

FR-A-749 479 describes a frame with three on top of each other arranged trays, individually around horizontal axes are pivotable. So the trays are horizontal or slightly inclined position suitable for placing goods. If you place all the trays vertically, you get a common one Presentation area to which goods can be attached. There is a perforated grid in the shelves for holding elements with which the goods to be displayed can be fixed are. The frame is positioned in front of a rear wall and all trays are aligned vertically - around a presentation area to form - you lose no space because the frame is close to the back wall. Shall the shelves you have to move the frame away from the back wall, to make room for the swiveling shelves. If you place the shelves in the back of the back wall Placed vertically again, the space remains between Unused frame and rear wall. As a consequence you have to either accept loss of space when moving the shelves or the entire frame to or from the back wall move away.

In the company publication "HUWIL adapter system, manual 930" of HUWIL-WERKE GmbH, furniture lock and fitting factories, Ruppichteroth / Germany, becomes a two-part fitting offered for furniture to adjust trays in the inclination to be able to. The trays are between two spaced vertical side supports used. There is a fitting from a toothed washer, which is arranged on the shelf, and a bearing inserted in the side support. The warehouse has a pocket in the bottom facing the tray there are towering teeth. In this, facing the tray Pocket, the toothed lock washer can be inserted from above, with the teeth in the pocket between the radial on the Engage toothed washer on existing teeth. When lifting the The teeth of the bearings and the tooth lock washers come into the tray disengaged, so that the tray is gradually inclined can adjust as desired. This fitting opens up limited uses and is also critical the unsecured detachability of a shelf by mere Lifting up. For shelf structures in sales or showrooms with larger public traffic and for customers, who want to examine the exhibited goods in more detail, the fitting is therefore unsuitable.

Object of the invention

In view of the aforementioned disadvantages of existing rack structures and the existing fittings, lies the invention the problem underlying a shelf with the slope propose adjustable shelves, taking the goods have it presented both horizontally and hanging and at the conversion of the shelves does not result in loss of space, nor moving the entire shelf with respect to a rear wall is necessary. Accordingly, there is a new concept for shelves and to develop a suitable fitting.

The shelf must be convertible in a few simple steps. The manufacture, erection and disassembly of the shelf should be possible in a rational and cost-effective manner. Further the shelf must match the existing room conditions on site or customer requests can be easily adjusted can. In addition to the essential stability and variability Supplementary elements are intended to hold the shelf structure Have the goods or decoration inserted harmoniously. Corresponding today's design requirements in shopfitting the shelf construction has a striking, individual design enable.

On the one hand, with the fitting to be created, assembly and facilitate dismantling of the shelf, on the other hand must the fitting allows the shelves to be adjusted securely over several Allow selectable positions. Even with a more turbulent crowd of buyers, where people of different intensity and from toast to the shelves in different positions should be through the constructive design of the fitting in any case an unintended Avoid lifting the shelf out of the frame will.

Essence of the invention

One inside the frame construction of a shelf on the side Supported shelf is horizontal Position swiveling into the vertical position and in the each selected position lockable. In horizontal or Goods can be placed on the tray in an inclined position hang up while in the vertical position in the am Have the tray provided with the perforated grid holders, that serve as direct goods carriers. Such mounts can e.g. Hanging bars, glasses or belt holders, Mirror sockets and tie bars, lamp or sign holders be.

Several trays are arranged one above the other so that neighboring, vertically placed shelves a common wall surface form. The trays are horizontal, rod-shaped Supports each with two two-piece fittings pivotally attached, the supports in the manner of Ladder rungs extend within the frame construction. The fittings are in the back of each shelf attached, the masculine parts of the fittings each to the side of the shelves and the female parts of the fittings are arranged on the adjacent side support.

The tray surface has a perforated grid with individual holes on, in the brackets with horizontal, strongly inclined or vertically standing shelf that can be inserted as direct Product carrier or for separating the presented goods to serve. The perforated grid laid out in rows and lines is appropriately designed so that the systematic distances in the perforated grid of a shelf also at the transition to one neighboring tray are observed. So you can too the individual tray-overlapping brackets, which at least extend to the next shelf, insert.

The fitting is made of a tooth lock washer, each on the side is arranged on the shelf, and one in the side support camp to be used. The camp points below, the Tray facing at least one upward tooth on. Preferably, several teeth are curved within one Tooth bridge available, which from a pocket radial collar is surrounded, which is about a lower Forms semicircle. Centrally located in the warehouse, above the tooth bridge a guide pin. In an advantageous variant two such bearings form a bracket, this one can be placed on the side support of the frame construction and point the bearings away from each other.

The lock washer belonging to each bearing - similar to a ring gear - has radially arranged teeth, which to the teeth are complementary in the warehouse. The tooth lock washer is in that Insertable bearing so that the teeth of the toothed disc and the bearing come into engagement with each other. In the tooth lock washer is a central recess and one from the outside groove running to this recess. So can the lock washer can only be inserted into the bearing if one guides the guide pin through the groove, which at completely inserted toothed lock washer can be accommodated in its recess. In this way it is possible to lift out the one used in the shelf Trays only possible in a certain inclination. It has proven to be expedient and particularly safe that two toothed lock washers on the shelf so that the insertion and lifting out the tray only in one to the rear inclined position is possible.

Embodiment

In the following the shelf and the fitting according to the invention with reference to the accompanying drawings described, finally possible modifications are mentioned.

The following definition applies to the entire further description. Are in a figure for the sake of graphic clarity Reference numbers included, but in the immediately associated Descriptive text not explained, so is on their Mention in previous figure descriptions reference taken. In the interest of clarity, the repeated designation of components in subsequent figures mostly dispensed with, provided that it is clearly recognizable in the drawing is that they are "recurring" components.

Figure 1A

The shelf has a frame construction 1 with the front vertical supports 11 and the side supports 12 extending horizontally and at right angles therefrom. Two vertical supports 11 each enclose a shelf field 10 . The side supports 12 are spaced parallel to one another here, similar to ladder rungs, and extend to a rear rear wall 13 . Vertical supports 11 and side supports 12 are made of round material in the example here. The left and right side supports 12 of a shelf field 10 are in pairs at one level. In the case of larger shelves, several shelf fields 10 can be present, the shelf height being determined by the spatial conditions and design aspects. The present example shows four side supports 12 lying one above the other and thus four shelves. In each case between two equally high side supports 12 is suspended a shelf 2 which can be tilted and which is held in each case by a laterally arranged fitting 3 . The fitting 3 is fastened on the one hand to the tray 2 and on the other hand to the side support 12 .

Apart from the process of hanging and unhooking, each tray 2 can be pivoted from a horizontal position into the vertical and can be locked in the respectively selected position. The horizontal or forward inclined position is used to place 2 goods on the tray. In the strongly downward inclined or vertical position, the function of the hole pattern 21 present in the trays 2 comes into play. The hole pattern 21 incorporated in the shelf surface 20 consists of holes 24 systematically distributed in rows 22 and rows 23 . The distance between the individual rows of holes 23 on a tray surface 20 preferably corresponds to the distance between two adjacent rows of holes 23 at the transition from two adjacent, vertically pivoted trays 2 . This is achieved by the design of the hole pattern 21 and the selected distance between the side supports 12 .

Holders 4 of various types - for example suspension rods 40 , edge boundaries 41 , eyeglass trays 42 or belt holders 43 , mirror frames 44 and tie clips, lamp or sign holders - can be inserted into the holes 24 . The brackets 4 serve as a direct carrier for the goods to be presented or for fastening for various elements such as lighting fixtures, mirrors, decorative elements or advertising information. The brackets 4 can have plug-in parts which can only be inserted into one hole 24 or at the same time into several holes 24 . Larger brackets 4 can therefore extend over more than one tray surface 20 .

The individual trays 2 can thus be positioned uniformly or differently within a shelf field 10 . If adjacent or all of the shelves 2 of a shelf field 10 are placed vertically, a quasi-closed presentation wall is obtained which is formed by the individual shelf surfaces 20 . To convert the shelf from the horizontal to the directly or indirectly hanging product presentation, all that is required is to adjust the shelves 2 and to insert the holders 4 provided .

Figure 1B

The tray 2 could be a metal sheet with outer bevels 25 . Advantageous has proven to be to arrange the fitting 3 at the rear side portion of a chamfer 25, as thus in an inclined or vertically inclined tray 2 is less unused space between the tray 2 and the rear wall 13 is formed.

Figure 1C

The two-part fitting 3 consists of a toothed lock washer 300 , which is arranged in the rear side area on the tray 2 , and a bearing 30 attached to the side support 12 . A U-shaped double bearing 5 has advantageously been created, which has two bearings 30 pointing away from one another. The double bearing 5 can be placed on the side support 12 in the manner of a saddle and serves to hang in two horizontally adjacent trays 2 . Both bearings 30 are therefore connected to one another by a bracket part 50 which rests on the side support 12 and partially encloses it in a form-fitting manner. The bracket part 50 is fixed to the side support 12 , for example by means of a screw 51 which engages in the side support 12 .

The bearing 30 has, at the bottom, facing the tray 2 , at least one tooth 31 directed upwards. Here there are several teeth 31 within a semicircularly curved, upwardly open toothed web 33 . A guide pin 35 projecting perpendicularly from the disk-shaped bearing surface 34 is located centrally in the bearing 30 , ie above the toothed web 33 . Tooth gaps 32 remain between the teeth 31 . The two lowest, fully formed teeth 31 enclose a tooth space 32 with tooth flanks that are in principle parallel, while the adjacent tooth spaces 32 have an enlarged opening angle. This facilitates the insertion of the toothed disk 300 attached to the tray 2 from above.

The toothed disk 300 belonging to each bearing 30 - similar to a toothed ring - has radially arranged teeth 331 with tooth gaps 332 , so that the toothed disk 300 can be inserted into the bearing 30 in any rotational position and the teeth 31, 331 mesh with one another. When the toothed disc 300 is inserted, its outer plane surface 334 is opposite the bearing surface 34 . A central recess 336 and a groove 335 running from the outside to this recess 336 are present in the toothed disk 300 . Thus, the toothed disc 300 can only be inserted into the bearing 30 if the guide pin 35 is guided through the groove 335 . When the toothed disc 300 is fully inserted, the guide pin 35 is located in the center of the recess 336 . In this way, the tray 2 inserted into the shelf can only be lifted out in a certain inclination position; analogously, the tray 2 can only be used in this inclined position. By the toothed disk 300 is threaded bores extending 337 which are provided for mounting on the shelf. 2

Figures 2A and 2B

To improve the lateral guidance of the toothed disk 300 used in the bearing 30 , a radial collar 38, which is placed on the toothed web 33 and runs as a lower semicircle, can be provided. This collar 38 can additionally be placed as a bracket or can be formed in one piece with the bearing 30 or the double bearing 5 . The collar 38 creates a type of pocket which shields the lower part of the teeth 331 of the toothed disk 300 seated in the bearing 30 from the outside.

Compared to the outer plane surface 334 , a reduced-diameter holding plate 338 can be placed on the toothed disk 300 , over which the teeth 331 protrude and which, in the inserted state, with its radial shoulder faces or is supported on the inner flank of the collar. The threaded holes 337 also penetrate the holding plate 338 . Due to the holding plate 338 , the recess 336 and the groove 335 are only open towards the flat surface 334 .

If a bearing 30 of a double bearing 5 is not occupied by a toothed washer 300 - that is, an adjacent tray 2 is not used, as is the case on the side shelf end - a blind cover 6 is available. The blind cover 6 closes the otherwise open bearing 30 .

Figures 3A to 3E

This schematic sequence of figures serves to describe the insertion of the tray 2 and the various possible settings of the inclination. It is assumed that the two toothed disks 300 are attached to the shelf 2 and are to be inserted into two open bearings 30 fixed to side supports 12 . Only a combination of the bearing 30 and the toothed disk 300 is shown , the holding plate 338 not appearing due to the vertical section made and the respective rotational position of the toothed disk 300 can thus be seen.

Figure 3A

It has proven to be expedient and particularly secure to attach the two toothed disks 300 to the tray 2 in such a way that the insertion and removal of the tray 2 is only possible in a position inclined to the rear. When inserting or lifting out the tray 2 , the tray 2 has to be tilted so that the tray level T drops towards the rear in relation to the horizontal H. The shelf surface 20 is offset in parallel above the shelf level T. In the position, the groove 335 in the toothed disk 300 points vertically downward and can therefore be pushed over the guide pin 35 . The tray 2 cannot be used in any other position, since the teeth 331 or the tooth gaps 332 hit the guide pin 35 . If the tray 2 has been inserted so far that the guide pin 35 has passed the groove 335 but the teeth 31, 331 are still out of engagement, the tray 2 can now be adjusted to a desired inclination, supported by a slight lifting.

Figure 3B

The tray 2 was pivoted into the horizontal H , in which the tray level T and consequently the tray surface 20 parallel to it now lie. By further lowering the tray 2 , the teeth 31, 331 come into engagement with one another and the guide pin 35 is centered in the recess 336 . In this horizontal position, the tray 2 is secured against unintentional ejection, since the guide pin 35 would butt against the inner wall of the recess 336th

Figure 3C

In order to tilt the tray 2 forward, it must first be raised so that the teeth 31, 311 disengage . Now the tray 2 can be pivoted and after the lowering the teeth 31, 331 are engaged again, as a result of which the new position of the tray 2 is fixed. The angle of inclination of the tray plane T with respect to the horizontal H is here α = 30 °. The gradation of the possible inclination positions depends on the fineness of the teeth.

Figure 3D

Shown is a steeper adjustment of the tray level T with an angle of inclination α = 60 °. As in the two previous positions, the tray 2 is also secured here against inadvertent ejection by the guide pin 35 seated in the center of the recess 336 and the groove 335 turned away.

Figure 3E

Finally, the vertical position of the tray plane T is shown with an inclination angle α = 90 °, ie the tray surface 20 is perpendicular with an adequate position of the groove 335 . Removing the tray 2 requires the previous lifting and pivoting back into the analog position according to FIG. 3A, where the guide pin 35 can slide through the groove 335 .

• Das Lochraster 21 auf den Tablarflächen 20 wäre verzichtbar, wenn man die Halterungen 4 nicht zum Einstecken gestaltet, sondern Klemmen vorsieht, die am Rand der Tablare 2 angreifen können.
• Als Rahmenkonstruktion 1 kommen auch brettförmige Vertikalstützen 11 mit horizontalen Seitenstützen 12 in Betracht. Die Seitenstützen 12, an den die Lager 30 befestigt sind, können auch vertikal verlaufen und als Brett ausgebildet sein. Massgeblich ist eine Befestigung der Lager 30, dass die Tablare 2 mit den angeordneten Zahnscheiben 300 einsetzbar sind.
• Das Regal ist auch unmittelbar an einer Wand aufstellbar, wodurch die Rückwand 13 unnötig wäre. Das Regal kann direkt am Fussboden aufsitzen oder beliebige sockelförmige Unterbauten besitzen.
• Als Tablare 2 sind Tafeln, Gitterroste und Bretter aus Blech, Kunststoff oder Holz einsetzbar.
• Für spezielle Anwendungsfälle wären auch arretierbare Positionen für die Tablare 2 denkbar, wo diese nach hinten geneigt sind.
• Je nach dem vorgesehenen Stellbereich der Tablare 2 müssen die Zähne 331 um die Zahnscheiben 300 nicht gänzlich radial umlaufend ausgebildet sein.
• Die Halterungen (4) sind auch bei horizontal ausgerichtetem Tablar (2) einsetzbar und würden dann vorrangig zur Separierung der präsentierten Waren dienen.
• Der Beschlag 3 ist auch in Verbindung mit in der Neigung oder in der axialen Drehstellung verstellbaren Tragstangen bzw. Abhängevorrichtungen einsetzbar. Hierbei ist die Zahnscheibe 300 an der Tragstange bzw. Abhängevorrichtung befestigt, während das Lager 30 feststehend an einer Stütze oder einer Wand sitzt.

The following modification options to the shelf and fitting described so far are expressly mentioned:

• The hole pattern 21 on the shelf surfaces 20 would be dispensable if the brackets 4 were not designed to be plugged in, but instead provided clamps which could engage on the edge of the shelves 2 .
• Board-shaped vertical supports 11 with horizontal side supports 12 are also suitable as the frame construction 1 . The side supports 12 to which the bearings 30 are attached can also run vertically and be designed as a board. It is essential that the bearings 30 are fastened so that the trays 2 with the toothed disks 300 arranged can be used.
• The shelf can also be set up directly on a wall, which would make the rear wall 13 unnecessary. The shelf can sit directly on the floor or have any base-shaped substructure.
• Boards, gratings and boards made of sheet metal, plastic or wood can be used as trays 2 .
• For special applications, lockable positions for the trays 2 would also be conceivable, where these are inclined backwards.
• Depending on the intended setting range of the trays 2 , the teeth 331 do not have to be completely radially circumferential around the toothed disks 300 .
• The brackets ( 4 ) can also be used with the tray ( 2 ) aligned horizontally and would then primarily serve to separate the goods presented.
• The fitting 3 can also be used in conjunction with support rods or suspension devices that can be adjusted in inclination or in the axial rotational position. Here, the toothed disc 300 is attached to the support rod or suspension device, while the bearing 30 is fixed on a support or a wall.
