Description

Slope support system

The present invention relates to a shelf support device according to the preamble of claim 1 with shelf accommodation devices or substantially grounded in the vertical direction for housing shelf supports in a substantially horizontal orientation, at least one support of shelf, preferably shelf plates for resting on the shelf supports, as well as at least one conductive rail device oriented substantially in the vertical direction, which conducts at least one electrical conductor for the electrical supply of electrical consumers that can be placed near each shelf stand.

Generic shelf support devices are used in particular in the field of merchandise presentation in the form of modular shelving sales shelves from profile racks. Here there is a need to have an electrical voltage on each shelf plate. This serves, for example, for the supply of lamps fixed on the shelf plates to illuminate the merchandise to be presented. When the goods to be presented are electronic products, such as razors or laptops, the power supply is required to present the product in operation. For aesthetic reasons, in this field it is required that the power supply be carried out with the least possible number of wired connections in sight. In particular, it is not desired that individual cable bundles of a voltage source be visibly directed to each individual shelf plate.

Therefore, the generic shelf support devices feature a conductive rail device, which ensures a power supply of the individual shelves of cordless shelf support devices that extend separately. The conductive rail is connected at one end with an external voltage source and can be fixed on the shelf support devices known of the type indicated at the beginning as an additional component in the shelf support device in an orientation that can be approximately vertical. Thus, in the state of the art, in the case of adequate sizing, the necessary tension can be taken on each shelf, without the cable having to be conducted directly from the external voltage source to the shelf plate in an aesthetically non- desirable.

In the prior art, rack support systems with separate conductor rails are used. The drawback of known shelf support devices is that a rear wall, which exists in many cases, which is located vertically between the shelf accommodation devices, must be specially adapted for the accommodation of the conductive rail. This makes it difficult to use standard shelving systems. On the other hand, the general structure of the shelf support devices according to the state of the art is relatively complex due to the number of individual components. In addition, in many cases a power supply that is optimally protected from sight is not possible, which is inconvenient.

From WO 002006067396 A 1 a device for presenting goods with a lighting element is already known. From DE 34 39 657 Al is known a shelf support device according to the preamble of claim 1. Therefore, the objective of the present invention is to improve a shelf support device of the type indicated at the beginning to avoid the indicated inconveniences. In particular, a

shelf support device, which is made up of fewer components and can also be used in combination with standard shelf support systems.

This objective is achieved according to the invention by means of a shelf support device of the type indicated at the beginning with the characteristics of claim 1, in which the conductive rail device is arranged inside the shelf accommodation device. The advantage of this arrangement is that the shelf housing device serves at the same time for power supply to the shelf plates. Therefore, an additional conductor rail can be advantageously dispensed with as in the prior art. In this way, for example, standard rear walls can be used, without other adaptations for the construction of a shelf support system. In addition, a power supply, for example for laptops or razors to be presented on the shelf plates, can be done better, without seeing the wires in an undesirable way. This is due to the fact that the subsequent distribution of the tension can be carried out, for example, inside the shelf support, since the conductive rail is arranged according to the invention inside the shelf housing devices.

According to the invention it is provided that at least one shelf support has means for establishing electrical contact with the electrical conductor by fixing it on the shelf housing device. In this way it is achieved that the tension conducted by the conductive rail inside the shelf housing device continues to be conducted automatically when the shelf support is inserted into the shelf support housing device. Therefore, an additional work stage for the establishment of an electrical connection is suppressed. Instead, according to the invention the electrical connection is established at the same time with the mechanical connection when building the shelf support system, which is an advantage.

Since according to the invention the means for establishing contact are made as pins, safe conduction of the power supply of the conductive rail can be achieved inside the shelf housing device to the shelf support and to the shelf plates that preferably rest there.

According to the invention, it is especially advantageous for the plug to have a clamping housing to establish a tightening connection with the shelf support. In the case of a suitable sizing of the clamping housing, thanks to this measure, standard shelf support systems can then be equipped with pins that can be fixed by tightening, to feed, for example, goods to be presented in the support system. Shelf with electric voltage.

In an advantageous configuration of the invention it is provided that the shelf accommodation devices are made as profiled supports. Thanks to this measure, shelf support systems that have yielded good results in practice, readily available, can be used advantageously to obtain the shelf support device according to the invention. In particular in the field of presentation of goods, thanks to a shelf support system comprising according to the invention profiled supports such as shelf accommodation devices, a modular shelving system can be made available that can be easily mounted and disassembled on site.

When the conductor rail device is made as a wire profile, it preferably has a

copper wire, in another advantageous configuration of the invention a reliable current conduction can be carried out and at the same time an electrical isolation of the shelving system itself. In addition, current standard conductor rails can be used advantageously in the market.

According to a preferred variant of the invention, at least one conductor rail device provided outside the shelf housing device is provided. The additional conductive rail device can be used to complement the conductive rails arranged according to the invention inside the shelf housing device in a conventional manner for power supply in the area of the shelf plates. In accordance with this variant according to the invention, for example, multi-pole constellations can also be made.

In another advantageous configuration of the invention, the shelf housing devices are configured as double profile housing, two conductive rail devices being arranged inside the double profile housing. In applications where the mechanical load capacity of the shelf supports has to be especially high, for example to represent heavy goods, double profile housings of this type are used in the usual shelf support systems. If used in connection with the present invention, a two-pole power supply can be carried out here, a conductive rail being driven in each partial housing of the double profile housing respectively.

A preferable embodiment of the invention will be explained by way of example with reference to a drawing, other advantageous details can be seen in the Figures of the drawing.

parts that have the same function are provided here with the same reference signs.

Figures in the drawing show respectively:

Figure 1 shows in the upper part the detail of a shelf support system according to the invention. A rear wall bracket 1 oriented in the vertical direction can be seen in the Figure. The rear wall bracket 1 is a jagged angular profile. In the rear wall support 1 a shelf support 2 is inserted. The shelf support 2 is made of aluminum. In the assembled state, the shelf support 2 is arranged at right angles to the rear wall support 1 and is therefore oriented in the horizontal direction. The shelf support 2 serves to rest the shelf plates not shown in the Figure. The connection between the rear wall support 1 and the shelf support 2 is formed by the cooperation of a pin 3 facing down from the shelf support 2 and a corresponding recess 4 in the rear wall support 1. The shelf support 2 and the rear wall bracket 1 correspond to modular shelving elements well known to the expert in

The matter. At an end facing the rear wall support 1 of the shelf support 2 an electric contact pin 5 is fixed.

The rear wall bracket 1 is surrounded by a plastic XT 6 support profile. The abbreviation "XT" means within the framework of this invention that the corresponding component has been manufactured in an extrusion process as an extruded part. Thanks to the fact that the rear wall support is surrounded by the XT 6 support profile, an aesthetic, especially slender embodiment of a shelf support system is achieved according to the invention. Here, the support profile 1 of aluminum is optically hidden in the rear area by the support profile XT 6 that surrounds it.

On a rear side 7 of the support profile XT 6 there is a wire profile XT 8 that is oriented in the vertical direction. In the wire profile, for example, a flat rail of low current voltage can be used in the market. It can be a component with an extruded aluminum profile, in which a plastic profile is enclosed with a built-in copper conductor. Components of this type are available with pre-punched elongated fixing holes for easy assembly. Multiple accessories are available for conductive rails of this type, such as power supplies, electrical longitudinal connectors, end caps and the like.

The contact pin 5 at the end of the shelf holder 2 has in particular a contact blade 9. The contact blade 9 protrudes from the contact pin 5 and the shelf holder 2 in the longitudinal direction thereof. As can be seen in the lower part of Figure 1, which represents a detail of the area marked with a circle in the upper area of the Figure, one end of the contact blade 9 of the contact pin 5 appears in the state mounted from the shelf support 2 to the inside of the rear wall bracket 1 and to the inside of the wire profile 8. In this way an electrical contact is established between the wire profile 8 and the contact blade 9.

Figure 2 shows a detailed representation of the contact pin 5 of Figure 1. In Figure 2, the contact pin 5 is represented as an individual component in a kind of representation exploded separately from the shelf support 2. How can see in Figure 2, the contact pin 5 is formed by a pin housing 10 with other components. The plug housing 10 is made in one piece. It is formed by two arms 12, 13 joined together by a flexible joint 11.

The arm 12 has a substantially rectangular outer support 14 for housing the contact blade 9. The outer support 14 has two openings 15 in the longitudinal direction of this arm 12 as opposed slits. The arm 12 is provided with a contact hole 16 between the outer support 14 and the flexible joint 11.

The second arm 13 of the pin housing 10 has an inner support 17 at the end not oriented towards the flexible joint 11. The inner support 17 also has openings 15 by way of slits in the longitudinal direction for the contact blade 9. The dimensions of the substantially rectangular inner support 17 are chosen such that the inner support 17 is pressurized with positive adjustment in the outer support 14 by retracting the arm 12 over the arm 13 and bending the flexible joint 11. A steel spring 18 has been placed above the contact knife 9.

For the assembly of the contact blade 9, it is inserted in such a way in the inner support 17 of the arm 13 that a

Shorter section 19 of the contact knife 9 protrudes through one of the openings 15 by way of slots of the pin housing 10. On the other side, a longer, opposite section 20 of the contact blade extends 9 in this state mounted through an opening 15 as an opposite slit in the direction of the flexible joint 11. Thanks to the mounting of this type of the contact knife 9 on the inner support 17 of the arm 13 of the plug housing 10, the contact blade 9 is tightened by the cooperation of a transverse section 21 with the inner support 17, on the one hand, and the recoil force of the steel spring 18 placed above the longitudinal section 20 with respect to the inner support 17, by other side.

The longitudinal axis 20 of the contact blade 9 has a hole 22. In the mounted state of the contact blade 9 in the pin housing 10, the hole 22 in the longitudinal section 20 of the contact 9 coincides with the contact hole 16 in the arm 12 of the pin housing 10. The hole 22 in the contact blade 9 is used for the accommodation of a pin 23 shown only schematically. The plug is not part of the contact pin 5.

Figure 3 shows the contact pin 5 of Figure 2 in a sectional view in a mounted state in the shelf support 2. It can be seen, in particular, that the pin housing 10 envelops the shelf support 2 and is attached thus staring with this. The wrapping is produced by the insertion of the open pin housing 10, in a state like that shown in Figure 2, in a housing 24 inside the shelf holder 2. In Figure 3 it can be clearly seen that the Longitudinal section 19 of the contact blade 9 protrudes from the pin housing 10.

In the lower part of Figure 3, the module formed by the rear wall bracket 1, the support profile XT 6 is shown in the same perspective and in a horizontal sectional view as in the upper part of Figure 3, as well as the wire profile 8 according to Figure 1. As can be seen in this view in horizontal section, the support profile XT is made as a double housing for housing a pair of shelf supports 2 in a pair of rear wall supports 1 The rear wall brackets 1 are housed with their housing pins 3 angled 909 as a pair in the support profile XT 6. Towards the rear side 7 of each housing section of the support profile XT 6, inside the profile of support XT 6 is respectively arranged the wire profile 8. In a notch 25 extending in a vertical longitudinal direction of each wire profile 8 a copper wire 26 is guided respectively.

A broken line 27 is shown in Figure 3 as one of the shelf supports 2, which is provided with the contact pin 5, is inserted in the support profile XT 6 with the rear wall support 1 and the wire profile 8 arranged behind.

Finally, Figure 4 shows in a perspective view the arrangements of Figure 1 for clarity. However, in Figure 4, unlike Figure 1, the shelf support 2 is not inserted in the rear wall support 1 to simplify the representation. Furthermore, the contact pin 5 is not mounted on the shelf support 2. Instead, said components can be separated from each other in a kind of exploded representation.

In order to start the shelf support system according to the invention with power supply, a

a certain number of XT 6 support profiles arranged at a desired distance from each other on a rear wall, which is not shown in the Figures. The support profile XT 6 is further provided with rear wall brackets 1, which are used for the accommodation of the shelf supports 2. The shelf supports 2 are used in this case for the accommodation of bottoms of shelves not shown.

Each shelf support 2 is then provided with a contact pin 5. For this purpose, the contact pin 5 is passed in the open state (see Figure 2) with the contact blade 9 inserted in the inner support 17 through the housings 24 in the shelf support 2. At the same time the arm 12 of the plug housing 10 is passed through the housing 24, until it reaches the flexible joint 11. Next, the flexible joint 11 is deflected, to insert by insert the outer support 14 in the arm 12 of the plug housing 10 with the inner support 17 in the other arm 13 of the plug housing 10. The core area 28 behind the recess 24 in the shelf support 2 is thus tightened by the plug housing 10. Thanks to this, the contact pin 5 is fixedly connected with the shelf support 2. In this state, the contact blade 9 protrudes with section 19 of shelf support 2.

The shelf support 2 is now hooked with the contact pin 5 connected by tightening as in a normal construction of a shelf support system with the pin 3 in the corresponding recesses 4 in the rear wall support 1. Thanks to that the section 19 of the contact blade 9 of the contact pin 5 protrudes from the shelf support 2, in the mechanical fixing of the shelf support 2 in the rear wall support 1 the contact blade 9 is inserted with the section 19 in the recess 25 of the wire profile 8. In this way an electrically conductive connection is established between the copper wire 26 located in the recess 25 and the contact blade 9.

As a consequence, in case of a corresponding connection of the copper wire 26 of the wire profile 8 with a voltage source a contact can be taken to which voltage is applied, by inserting a pin 23 that is located in the shelf plate through of the contact hole 16 in the hole 22 of the contact blade 9. The cable conduction of the pin 23 can be carried out here for example below a shelf plate that rests on the shelf holder 2 and can therefore be hidden in sight, as is desirable in the presentation of goods.

The contact establishment is carried out in the construction of the shelf support system automatically when fixing the shelf support 2 mechanically. Advantageously, a separate conductor rail can be renounced on the rear wall of the shelf support system. Thanks to the property of the XT 6 support profile of being a double housing for the accommodation of two shelf supports 2, for example, a two-pole power supply can be carried out. The copper wire 26 in the wire profile 8 can be connected, for example, as a positive pole inside the rear wall bracket 1 left, while the copper wire 26 in the wire profile 8 inside the wire holder rear wall 1 right can be connected as negative pole. A connection with three poles can also be made analogously.

Therefore, according to the invention, a shelf support device has been proposed, which allows an especially aesthetic construction, since additional or similar conductive rails are not necessary on the rear wall. It is especially easy to mount a rack support system of this type,

for example for the purpose of presenting merchandise, the merchandise to be supplied with electric voltage must be supplied. This is because during the mechanical fixation of the shelf supports 2 on the rear wall support t a contact establishment also takes place automatically with the pin fixed on the shelf support 2. This is achieved surprisingly simply, because The wire profile 8 is arranged inside the system formed by the rear wall bracket and the support profile XT.
