Description

The present invention relates to a floor support device according to the preamble of patent claim 1 with substantially vertically oriented floor receiving devices for receiving floor supports in substantially horizontal orientation, at least one floor support, preferably floor panels for resting on the floor supports and at least one substantially vertically oriented, at least an electrical conductor leading busbar device for the electrical supply of placeable in a vicinity of each floor support electrical consumers.

Generic floor support devices are used in particular in the field of merchandise presentation in the form of modular shelves made of profile frames. Here there is a need to have an electrical voltage available on each floor panel. This serves, for example, to supply luminaires mounted on the floor panels for illuminating the product to be presented. If in the product to be presented to electronic goods, such. As shavers or laptop computers, the power supply is required to present the product to be presented in operation. For aesthetic reasons, there is a requirement in this area for the voltage to be supplied with as few visible cable connections as possible. In particular, it is undesirable that individual cable strands are visibly guided by a voltage source to each individual floor panel.

Therefore, the generic floor support devices on a busbar device, which ensures a power supply to the individual floors of the floor support device without separately extending cable. The busbar is at one end with a connected external voltage source and can be attached in the known floor support devices of the type mentioned as an additional component to the floor support device in approximately vertical orientation. This makes it possible in the prior art with suitable design on each floor tap the required voltage without a cable would have to be performed directly from the external power source to the floor plate in aesthetically undesirable form.

In the prior art floor support systems are used with separate busbars. A disadvantage of the known floor support devices is that a frequently existing rear wall, which is located vertically between the floor receiving devices, especially for receiving the busbar must be adjusted. The use of standard shelving systems is made more difficult. On the other hand, the general structure of the floor support device according to the prior art by the number of individual components is relatively complex. Furthermore, an optimal, sight-protected voltage supply is often not possible with disadvantage in many cases.

From the WO002006067396A1 a device for displaying goods with a lighting element is previously known. From the DE 34 39 657 A1 a floor support device according to the preamble of claim 1 is known. Object of the present invention is therefore to improve a floor support device of the type mentioned in order to avoid the disadvantages mentioned. In particular, a floor support device is to be specified, which is constructed from fewer components and which can also be used in conjunction with standard carrier systems.

This object is achieved by a floor support device of the type mentioned above with the features of claim 1, wherein the busbar device is disposed within the floor-receiving device. The advantage of this arrangement is that the floor-receiving device serves simultaneously to supply power to the floor panels. An additional busbar as in the prior art can thus be omitted with advantage. This allows z. B. use standard rear walls without further adjustments to build a floor support system. Furthermore, it is advantageous to realize a voltage supply for example, to be presented laptop computer or razors on the floor panels better, without cables are visible in an undesirable manner. This is because the further stress distribution z. B. can be done within the floor support, since the busbar according to the invention is arranged within the floor receiving devices.

According to the invention it is provided that at least one floor support has means for making electrical contact with the electrical conductor due to the mounting in the floor receiving device. In this way, a forwarding by the busbar within the floor-receiving device guided voltage within the floor support is automatically effected when inserting the floor support in the floor support-receiving device. It thus eliminates an additional operation to make an electrical connection. Instead, it is advantageously produced according to the invention, the electrical connection simultaneously with the mechanical connection in the construction of the floor support system.

Since according to the invention, the means for contacting are formed as a plug, a secure redistribution of the electrical supply from the busbar within the floor receiving device for floor support and there preferably lying on the floor panels is achieved.

It is particularly advantageous according to the invention that the plug has a clamping housing for producing a clamping connection with the floor support. With a suitable design of the terminal housing standard carrier systems can be retrofitted with clamped plugs by this measure to provide, for example, to be presented on the floor support system with electrical voltage.

In an advantageous embodiment of the invention it is provided that the floor receiving devices are designed as profile carrier. By virtue of this measure, it is advantageously possible to resort to proven, readily available floor support systems in order to arrive at the floor support device according to the invention. In particular, in the field of goods presentation can be provided by a floor support system, which according to the invention comprises profile support as floor-receiving devices, a locally easily buildable and degradable modular shelving system.

If the busbar device is designed as a wire profile, preferably having a copper wire, in another advantageous embodiment of the invention a reliable current conduction with simultaneous electrical insulation from the shelf system itself can be realized. In addition, standard busbars can be used with advantage on the market.

According to a preferred variant of the invention, at least one busbar device arranged outside the storey receiving device is provided. The additional busbar device, in addition to the present invention within the floor receiving device arranged busbars in a conventional manner to the power supply in the field of Floor panels are used. For example, multi-pole constellations can be realized according to this variant of the invention.

In another advantageous embodiment of the invention, the floor receiving devices are designed as a double profile recording, wherein two busbar devices are arranged within the double profile recording. In applications in which the mechanical load-bearing capacity of the floor supports must be particularly high in order, for example, to represent heavy goods, such double-profile receivers are used in conventional floor support systems. When used in conjunction with the present invention, a two-pole voltage supply can be realized here by a respective bus bar is guided in each partial receiving the Doppelprofilaufnahme.

The rear wall support 1 is a serrated angle profile. In the rear wall support 1 a floor support 2 is used. The floor support 2 is made of aluminum. When installed, the floor support 2 is at right angles to the rear wall support 1 and is thus oriented horizontally. The floor support 2 serves the floorboards, not shown in the figure for support. The connection between the rear wall support 1 and the floor support 2 is formed by the interaction of a downwardly directed pin 3 of the floor support 2 and a corresponding recess 4 in the rear wall support 1. The floor support 2 and the rear wall support 1 correspond to the well-known system shelf elements. At an end of the floor support 2 facing the rear wall support 1, an electrical contact plug 5 is fastened.

In a rear side 7 of the XT carrier profile 6, an XT wire profile 8 is arranged vertically aligned. In the wire profile, for example, a commercially available low-voltage flat rail can be used. This may be an extruded aluminum profile component incorporating a plastic profile with an embedded copper conductor. Such components are available with pre-punched mounting slots to facilitate assembly. For such busbars extensive accessories are available, such. As feeder, electrical connectors, end caps and the like.

The contact plug 5 at the end of the floor support 2 has in particular a contact blade 9. The contact blade 9 projects beyond the contact plug 5 and the floor support 2 in the longitudinal direction beyond this. As in the lower part of the FIG. 1 , which shows a detailed representation of the circled in the upper part of the range area to recognize, one end of the contact blade 9 of the contact plug 5 protrudes in the installed state of the floor support 2 in the rear wall support 1 and in the wire profile 8. As a result, an electrical contact between the wire profile 8 and the contact blade 9 is produced.

The FIG. 2 shows in a detailed view of the contact plug 5 FIG. 1 , In FIG. 2 the contact plug 5 is shown as a single component in a kind of exploded view separated from the floor support 2. Like in the FIG. 2 to recognize the contact plug 5 consists of a connector housing 10 with other components. The connector housing 10 is integrally formed. It consists of two legs 12, 13 connected together via a bending joint 11.

The leg 12 has a substantially rectangular outer socket 14 for receiving the contact blade 9. The outer socket 14 has in the longitudinal direction of this leg 12 two opposite gap-like openings 15. The leg 12 is provided between the outer frame 14 and the bending joint 11 with a contact bore 16.

The second leg 13 of the plug housing 10 has an inner socket 17 at the end facing away from the bending joint 11. The inner frame 17 also has longitudinally slit-like openings 15 for the contact blade 9. Dimensions of the substantially rectangular line frame 17 are selected so that the inner frame 17 is pressed by folding the leg 12 on the leg 13 by bending the bending joint 11 into the outer frame 14 in a form-fitting manner. The contact blade 9 is slipped over with a steel spring 18.

For installation of the contact blade 9 this is inserted into the inner frame 17 of the leg 13 such that a shorter portion 19 of the contact blade 9 protrudes through one of the gap-like openings 15 on the connector housing 10. On the other hand, a longer, opposite portion 20 of the contact blade 9 extends in this installed state through an opposite gap-like opening 15 in the direction of the bending joint 11. By such installation of the contact blade 9 in the inner frame 17 of the leg 13 of the connector housing 10 is the Contact blade 9 by the interaction of a transverse section 21 with the inner frame 17 on one side and the restoring force of the struck on the longitudinal portion 20 steel spring 18 against the inner frame 17 clamped on the other side.

The longitudinal axis 20 of the contact blade 9 has a bore 22. In the installed state of the contact blade 9 in the connector housing 10, the bore 22 in the longitudinal portion 20 of the contact 9 in coincidence with the contact hole 16 in the leg 12 of the connector housing 10. The bore 22 in the contact blade 9 is used to receive a shown only schematically Plug 23. The plug is not part of the contact plug. 5

The FIG. 3 shows the contact plug 5 FIG. 2 in a sectional view in a mounted with the floor support 2 state. It can be seen in particular that the connector housing 10 encloses the floor support 2 and is firmly connected in this way. The enclosing takes place by inserting the unfolded plug housing 10, in a condition as in FIG FIG. 2 shown in a receptacle 24 within the floor support 2. It can be clearly seen in FIG. 3 in that the longitudinal section 19 of the contact blade 9 projects beyond the plug housing 10.

In the lower part of the FIG. 3 is in the same perspective and in a horizontal sectional view as in the upper part of FIG. 3 the assembly consisting of the rear wall support 1, the XT support profile 6 and the wire profile 8 according to FIG. 1 illustrated. As can be seen in this horizontal sectional view, the XT carrier profile is formed as a double receptacle for receiving a pair of floor supports 2 in a pair of rear wall beams 1. The rear wall support 1 are added with their 90 ° angled receiving pin 3 in the XT carrier profile 6 as a pair. To the rear side 7 of each receiving section of the XT carrier profile 6, the wire profile 8 is arranged inside the XT carrier profile 6. In a vertical longitudinal direction of each wire profile 8 extending notch 25 each have a copper wire 26 is guided.

By a dashed line 27 is in FIG. 3 indicated as one of the floor support 2, which is provided with the contact plug 5, in the XT carrier profile 6 with the rear wall support 1 and the wire profile 8 arranged behind it is to be introduced.

Finally shows FIG. 4 in a perspective view of the conditions FIG. 1 for further clarification. In the FIG. 4 is different from FIG. 1 for illustrative reasons, the floor support 2 is not inserted into the rear wall support 1. Furthermore, the contact plug 5 is not installed in the floor support 2. Instead, the components mentioned can be seen separately from each other in a kind of exploded view.

In order to operate the floor-support system according to the invention with electrical supply, a number of XT support profiles 6 are mounted at a desired distance from each other on a rear wall, which is not shown in the figures. The XT carrier profile 6 is further provided with rear wall supports 1, which serve to receive the floor support 2. The floor supports 2 are then used to hold in the figures, not shown shelves.

Each floor support 2 is then provided with a contact plug 5. For this purpose, the contact plug 5 in the unfolded state (see FIG. 2 ) inserted with the inserted in the inner frame 17 contact blade 9 through the receptacles 24 in the floor support 2. In this case, the leg 12 of the plug housing 10 is inserted through the receptacle 24 until the bending joint 11 is reached. Subsequently, the bending joint 11 is deflected to assemble the outer socket 14 in the leg 12 of the plug housing 10 with the inner socket 17 in the other leg 13 of the plug housing 10. The web portion 28 behind the recess 24 in the floor support 2 is thereby clamped by the connector housing 10. As a result, the contact plug 5 is firmly connected to the floor support 2. In this state, the contact blade 9 projects with the portion 19 beyond the floor support 2.

Now the floor support 2 is hooked with the clamped contact plug 5 as in the normal construction of a floor support system with the pin 3 in the corresponding recesses 4 in the rear wall bracket 1. Characterized in that the portion 19 of the contact blade 9 of the contact plug 5 projects beyond the floor support 2, the contact blade 9 is introduced with the portion 19 in the notch 25 of the wire profile 8 in the mechanical fastening of the floor support 2 to the rear wall support 1. This produces an electrically conductive connection between the copper wire 26 located in the notch 25 and the contact blade 9.

As a result, with appropriate connection of the copper wire 26 of the wire profile 8 with a voltage source, a voltage-bearing contact can be tapped by a located on the floor plate plug 23 is inserted through the contact hole 16 in the bore 22 of the contact blade 9. The cable guide of the plug 23 can be done here, for example, below a aufzusetzenden on the floor support 2 floor plate and thus be removed from the visual access, as desired in the presentation of goods.

The contacting takes place automatically in the construction of the floor support system when mechanically attaching the floor support 2. It is advantageous to dispense with a separate busbar in the rear wall of the floor support system. Due to the property of the XT carrier profile 6 to be a double receptacle for receiving two floor supports 2, z. B. constructed a two-pole supply become. The copper wire 26 in the wire profile 8, for example, within the left rear wall support 1 can here z. B. can be switched positively whereas the copper wire 26 in the wire profile 8 within the right backplane 1 can be switched negative. Likewise, a three-pole circuit can be realized in an analogous manner.

Thus, a floor support device is proposed according to the invention, which allows a particularly aesthetic design, since no additional busbars or the like are required in the rear wall. The installation of such a floor support system, for example, for purposes of merchandise presentation, the product to be presented with electrical voltage to be supplied, is particularly easy. This is due to the fact that, when the floor support 2 is mechanically fastened to the rear wall support 1, there is automatically a contacting of the plug fastened to the floor support 2. This is achieved in a surprisingly simple manner in that the wire profile 8 is arranged within the system of rear wall support and XT carrier profile.
