Description

The invention relates to a device for carrying objects, in particular goods for the presentation of goods, having the features of the preamble of claim 1.

Various devices for presenting goods are known from the prior art, in which on wall elements brackets, brackets and / or hangers of goods are shown. In particular, for the shop equipment and shop fitting devices are desired that allow easy mounting or dismounting of goods carriers on the corresponding wall elements, such as holding profiles, to be able to change an arrangement for displaying goods as needed.

Recently, there are efforts to expand the function of the goods carrier. This is what a device looks like DE 10 2007 020 125 A1 Data lines in the goods carrier in order to retrieve various information stored on the goods carrier goods. In another device according to EP 1 476 048 B1 The provision of lighting elements on the goods carrier is possible by supplying electrical energy via the holding profile in the goods carrier. However, this extension of the functionality of the product carrier is associated with a high installation and security effort, since the 220V power conductors may be installed only by specialized personnel. This severely limits the variability in shopfitting. In addition, safety regulations must be adhered to in such electrical systems and not inconsiderable additional energy costs are incurred.

An improved device shows the utility model DE 20 2008 003 360 U1 , Here low-voltage power conductors are used for the electrical installation, which supply the corresponding consumers on the goods carriers with the necessary electrical energy. This leads to a considerable energy saving and, moreover, simplifies the device, since lower safety requirements are met. The device shown is equipped with conductor tracks in the wall-side rail. Even if these tracks are openly accessible, this poses no danger, as even unwanted contact with the low-voltage power conductors does not lead to a life-threatening situation. A disadvantage of this device, however, is that in the wall-side current profile shown by a foreign object that is introduced, for example, in the opening of the rail, a short circuit can easily be triggered because easily such an object both tracks can be contacted. In addition, it is to be expected in the adapter described there that not every plug connection between a stocked with the adapter product carrier and equipped with the power profile rail also leads to an electrical connection, since the spring-loaded contacts arranged in the adapter are very tolleranzempfindlich and these contacts to meet point-shaped contact points of circular traces in the current profile.

The object of the present invention is therefore to provide a device for carrying objects, in particular goods for the presentation of goods, which enables easy assembly and disassembly of the goods carriers and does not have the disadvantages of the prior art.

This object is achieved with a device having the features of claim 1. This device has a wall mounted or embedded in a wall holding profile, such as an extruded aluminum hollow profile. Held on this holding profile, one or more goods carriers, which are for receiving, for example, for hanging or hanging, to serve goods. In such a product carrier may be, for example, a support floor made of different materials or a glass plate. Modifications of the invention for use in a mounting bracket, arm or other forms of goods carriers are possible by expert action. The product carrier is releasably held in the retaining profile via a plug connection. For this purpose, the retaining profile has a U-shaped receptacle extending in the longitudinal direction of the profile and open towards the outside. Here, the goods carrier can intervene with its rear end or provided on the goods carrier support arms. The product carrier has to extend its functionality electrical consumers, such as lighting units, such as light-emitting diodes, displays or other other communication units that can be supplied via electrical low-current trains as tracks with the necessary energy.

The supply of electrical energy takes place starting from a current source via conductor tracks in the holding profile and via an electrical connection between the conductor tracks in the holding profile with the conductor tracks of the goods carrier up to the consumer. The electrical connection is closed when inserting the waiting support in the recording in the holding profile. In the case of the present connector, the electrical conductive contact points of the conductor tracks provided on the goods carrier contact the conductor tracks in the retaining profile. The necessary power source can be provided on the retaining profile. In another embodiment, traces are guided out of the holding profile out to a power source. Preferably, this is done on the retaining profile end-closing end pieces.

Particularly advantageous in the device according to the invention is the configuration and arrangement of the contacts both on the holding profile and on the goods carrier. Thus, the conductor tracks are arranged in the holding profile so that a conductor track is provided on the rear wall of the holding profile or a wall arranged parallel to the rear wall in the holding profile and a conductor track on the underside of the receptacle in the holding profile or arranged parallel to the bottom wall in the holding profile becomes. In this way the two provided in the holding profile traces have a vertical orientation to each other. In the same orientation, the source-side contact points of the conductor tracks of the goods carrier are provided. The electrical conductor tracks in the holding profile can be connected directly to the retaining profile, if the retaining profile consists of an insulating material. In the case of metallic holding profiles, a separate contact rail, for example an extruded plastic profile rail, is preferably provided, which is equipped with the electrical conductor tracks. This contact rail is preferably a cross-sectionally L-shaped profile, wherein the two legs of the plastic profile are perpendicular to each other and have holding means for the conductor tracks. A trace is placed on the upright leg. This is preferably a rectangular in cross-section, extending in the longitudinal direction of the holding profile metal rail or a metal strip, said conductor over the entire longitudinal extent of the holding profile forms a wide, vertically extending contact surface for on-demand contacting. The other substantially horizontally extending trace is fixed to the horizontal leg of the contact rail. This conductor track is preferably a cross-sectionally S-shaped metal strip, which extends over the entire longitudinal extent of the holding profile. Since this metal strip is fixed to the contact rail only in the lower region, the upper region of the metal strip forms a spring with a contact surface extending substantially horizontally. The so populated contact rail is positively received in the receptacle of the retaining profile, for example, laterally inserted into the contact rail. If the contact rail is arranged in the retaining profile, the retaining profile has contacting possibilities over its entire longitudinal extent, namely the vertical or horizontal contact surface of the two conductor tracks. The configuration of the strip conductors and their arrangement in the holding profile or in the contact rail can also be realized in other ways. It is essential, however, that results in a vertically arranged and a further horizontally disposed, possibly over the entire longitudinal extent extending contact surface on the holding profile.

These contact surfaces of the holding profile get into electrical connection with the source-side contact points of the conductor carriers provided on the product carrier as soon as the product carrier is inserted into the receptacle on the holding profile. The conductor tracks provided for the goods carrier have consumer-side contact points for the contact with the consumer and, at the source side, the electrically conductive contacts of the conductor tracks contact the above-described contact surfaces of the conductor tracks on the holding profile. The source-side contact points of the conductor tracks on the goods carrier are preferably accommodated in a contact housing of an adapter, which is connected to the goods carrier. In order to enable a contacting of the above-described contact surfaces of the conductor tracks on the holding profile, these contacts must be aligned accordingly.

In a preferred embodiment, a source-side contact is provided as a pin contact. This is arranged in a horizontal orientation, ie the transverse direction to the holding profile in the adapter, so that it bounces when inserting the goods carrier against the vertical contact surface. Another source-side pad is provided in vertical alignment, i. contacted in vertical direction based on the holding profile. This contact may be, for example, a spring-mounted contact. When the product carrier is inserted, this contact touches the horizontal contact surface of the conductor track provided on the holding profile.

To connect the adapter with the goods carrier different versions are possible. If the goods carrier is, for example, a glass plate, then the contact housing of the adapter can be received in a form-fitting manner in a mold recess of the glass plate in a form-fitting manner. Such a mold cavity is preferred and round or oval for the sake of simplicity. The emerging from the contact housing conductor tracks may be formed for such a glass plate as a transparent film line, which is glued to the goods carrier, ie the glass plate. This adhesive joint can be at the top, at the bottom or in laminated glass between the Glass plates may be provided when, for example, the consumer is embedded in the laminated glass plate in the laminated glass plate.

In another embodiment, where the goods carrier is held by means of support arms on the holding profile, the mold recess for the contact housing of the adapter may be provided on a support arm, so that the contact housing of the adapter is also held in the support arm positively. The ladder tracks leading out of the contact housing are received protected in a sleeve of the support arm. These sleeves of the support arm can be arranged on the bottom or top of the product carrier. However, these are preferably introduced into cylindrical recesses which extend from the rear end side of the goods carrier. One of these cylindrical recesses extends to the consumer, so that the consumer-side contact points of the electrical conductor tracks contact the consumer in the goods carrier when inserting the adapter arm provided with the adapter.

The device according to the invention is easy to handle and can therefore be used advantageously particularly in shop fitting, since both assembly and disassembly of the goods carrier on the wall-side holding profiles can be made as needed, without the need specialist personnel is necessary. This facilitates a quick rebuild to be able to present new goods also new. Furthermore, only low electrical energy, for example for lighting, is consumed by the low-current paths used as conductor tracks. The equipped with the adapters goods carrier can be inserted in the simplest way to the holding profiles by a plug connection. It is also achieved in manufacturing tolerances on the goods carrier secure contact, since the protruding at the back of the product carrier pin contact when inserting the goods carrier against a wide contact surface provided on the holding profile conductor path and the second provided on the goods carrier source-side contact on the spring in the Holding profile stored conductor slides.

Fig. 2 shows the device 10 of Fig. 1 before assembly. You can see the wall-side support rail 20. The attachment to the wall is not shown in the embodiments. This retaining rail 20 may also be installed in a wall or be part of a shelf, cabinet or other piece of furniture or framework. The retaining rail 20 is equipped with the contact rail 30. The product carrier 40 has on its upper side 44 formed as an elongated hole groove 46 for the consumer 42. Furthermore, in the goods carrier 40, two cylindrical recesses 47, 47 'are provided, which extend from the back 41 of the goods carrier 40 in this, wherein the cylindrical recess 47 extends to the channel 46. These cylindrical recesses 47, 47 'receive support arms 60, 60', which are inserted from the back 41 of the goods carrier 40. In this example, two support arms 60, 60 'are provided. For smaller goods carriers 40 and a support arm 60 is sufficient and with wider goods carriers 40 and more support arms 60, 60 'can be provided. The support arm 60 'is solely the support of the goods carrier 40. The support arm 60 is additionally equipped with an adapter 50, in addition to the mechanical connection between the holding section 20 and goods carrier 40 in addition also an electrical connection from the consumer 42 to the provided on the support section 20 traces 33, 34 to create. At the end of the support arms 60, 60 ', a fastening part 61, 61' is provided. The support arms 60, 60 'are as far inserted into the recesses 47, 47' of the goods carrier 40 that they have a position as in Fig. 3 shown, take. After this mounting, the fastening parts 61 project beyond 61 ', the rear side 41 of the goods carrier 40. The protruding from the goods carrier 40 parts of the support arms 60, 60' are inserted for connection to the holding section 20 in this and are then no longer visible. After the presence of the connector, so the holder of the goods carrier 40 on the support section 20, as in Fig. 1 Thus, the electrical connection between the consumer 42 and the electrical conductor tracks 33, 34 in the holding profile 20 is thus also produced, so that, for example, illumination by the consumer 42 on the product carrier 40 can take place. Of course, the consumer 42 arranged on the upper side 44 can also be arranged on another side of the goods carrier 40, for example on the lower side 45. This consumer 42 may also or additionally be a display, another lighting unit or another electrical consumer.

In Fig. 4 the holding profile 20 is shown together with another product carrier 40 '. This is a glass plate, which has on its rear end face a mold recess 43 for an adapter 50 '. Not shown is the consumer 42, which is arranged on the underside of the glass plate. This consumer 42 is contacted via the electrical conductor tracks 53, 54. On the source side, these conductor tracks 53, 54 are provided with contacts 55, 56 which, upon insertion of the goods carrier 40 'with its rear end edge into the holding profile 20, come into contact with the conductor tracks 33, 34 of the contact rail 30.

The goods carriers 40, 40 'can be plugged in at any desired location in the longitudinal direction 80 of the holding profile 20 and contact the printed conductors 33, 34 provided there. The holding profile 20 is better Fig. 5 to see. This holding profile 20 has a C-shaped receptacle 21 open in the front. In the opening 22 of the receptacle 21, goods carriers 40, 40 'or other goods carriers can be inserted. The retaining rail 20 is equipped with a contact rail 30. This is a cross-sectionally L-shaped plastic profile. On upright legs 31 of the contact rail 30, the conductor 33 via holding means 37, 37 'fixed and on the horizontal leg 32 holding means 38, 38 'are provided for the conductor 34, this is better Fig. 8c to see. The contact rail 30 is positively received in the retaining profile 20. In this case, in the rear region of the receptacle 21. The shape of the receptacle 21 is adapted in this area to the shape of the contact rail 30 in order to ensure a positive connection. However, other shapes or connections are possible. The contact rail 30 can be inserted laterally into the retaining profile 20 for connection to the retaining profile 20. In the front region of the receptacle 21, a support profile 70 is additionally provided in this example.

In the holding profile 20, the electrical power supply for the conductor tracks 33, 34 is realized via an end-side end piece 24. The arranged in the holding profile 20 contact rail 30 projects beyond the retaining section 20 end, so that it can be easily inserted into the end piece 24. In this end piece 24 corresponding contacts for the conductor tracks 33, 34 are provided. In addition, a grounding of the retaining profile 20 can be made. Other lines lead from the tail 24 to a corresponding power source. This power source then supplies the electrical energy to the conductor tracks 33, 34 and when the goods carrier 40 is inserted, as in FIG Fig. 1 As shown, the source-side contacts of the conductor tracks 53, 54 provided on the product carrier 40 come into contact with the conductor tracks 33, 34 provided on the holding profile 20, so that the connection to the consumer 42 is established.

The source-side contacts 55, 56 of the provided on the product carrier 40 traces 53, 54 are housed in a contact housing 51 of the adapter 50. In the embodiment according to Fig. 3 with the product carrier 40 and the support arms 60, 60 ', the adapter 50 is arranged on the support arm 60. This connection is better from the Fig. 6a and Fig. 6b to see. The support arm 60 consists of a fixing part 61 and a cylindrical sleeve 62, which are interconnected. In the fastening part 61 a round mold recess 63 for the round contact housing 51 of the adapter 50 is present. In addition, two wings 64 are adjacent to the mold recess 63, 65 designed so that they cooperate for a positive connection with adjacent to the contact housing 51 provided supports 58, 59, as is apparent from Fig. 6a can be seen. The electrical conductor tracks 53, 54 are not received by the contact housing 51, which would be possible in another design of a contact housing. In the connection of adapter 50 and support arm 60, the electrical traces 53, 54 are received by the sleeve 62 of the support arm 60 and project end to end out of the sleeve 62 to, as from Fig. 2 can be seen when plugged support arm 60 in the recess 47 of the product carrier 40 to contact the consumer 42 at a corresponding contact point or contact surface. These consumer-side contact points of the interconnects 53, 54 can of course also be adapted accordingly to the contact points 42 present at the consumer in order to ensure a secure contact.

Fig. 7a shows a further form of an adapter 50 '. Such an adapter 50 'is provided when a goods carrier 40, 40' without support arms 60, 60 'to be fixed to the support section 20. In this case advantageously has the goods carrier 40 ', as in Fig. 4 shown, a corresponding mold recess 43 for the contact housing 51 'of the adapter 50'. Of course, the adapter can also be connected in other ways with the product carrier 40 '. However, this arrangement has the advantage that in the case of the goods carrier 40 'mounted on the holding profile 20, the adapter 50' is located within the receptacle 21. The conductor tracks 53, 54 of the adapter 50 'are designed in this case as a foil line 52 and are fixed to the underside of the goods carrier 40' by an adhesive connection.

Fig. 7b shows the adapter 50 'in a side view. Here it is readily apparent that the one contact 55 protrudes forward out of the contact housing 51 ', whereas, on the other hand, the second contact 56 is provided on the underside of the contact housing 51'. The same arrangement is in the adapter 50 of Fig. 6a and Fig. 6b to find where the pin contact 55, the adapter housing 51 projects beyond the front. The second contact 56 on the underside of the adapter housing 51 is not to be seen here. If a product carrier 40, 40 'is now equipped with such an adapter 50, 50' and inserted into the holding profile 20, then the contact housing 51, 51 'disappears within the receptacle 21 of the holding profile 20 and is not visible to the observer, which is desired ,

The mechanical and electrical connection of the goods carrier 40, 40 'with the holding profile 20 is better from the Fig. 8a, 8b and 8c seen. The Fig. 8a shows again the holding profile 20, in this case as a cross section. The holding profile 20 has the front open receptacle 21 for the goods carrier 40, 40 '. These goods carriers 40, 40 'are inserted through the opening 22 in the receptacle 21. Adjacent to the opening 22 in the front region of the receptacle 21, an undercut longitudinal groove 23 for the support of the support profile 70 is provided. The rear portion of the receptacle 21 is designed so that the contact rail 30 can be received positively. For the vertical leg 31 of the contact rail 30, an upper groove 27 is provided. This leg 31 otherwise applies to the back 26 of the receptacle 21. The horizontal leg 32 of the contact rail 30 rests on the underside 28 of the receptacle 21 and is also received at its free end by a groove 29. In addition, a latching connection is provided, effected by a clamping lip 25 extending in the longitudinal direction 80 which is formed on the underside 28 of the receptacle 21 and engages in a longitudinal groove 39 on the underside of the contact rail 30.

In the equipped with the contact rail 30 retaining profile 20, a product carrier 40 is inserted at any point in the longitudinal direction 80 through the opening 22. The insertion direction is the transverse direction 81. If the product carrier 40 is completely inserted, then the situation results, as shown in FIG Fig. 8b , The fastening part 61 of the support arm 60, which is connected to the goods carrier 40, is inserted into the receptacle 21 of the holding profile 20 and thus also the contact housing 51, which is received positively on the fastening part 61. In the side view of Fig. 8b is to be seen by the adapter 50, only the side wall of the support 58 and the protruding from the hontaktgehäuse 51 contacts 55, 56th in the transverse direction 81st aligned pin contact 55 abuts against aligned in Senkrechtrichtung 82 contact surface 35 of the conductor 33 and acting in Senkrechtrichtung 82 contact 56 is applied to the conductor 34 at. In particular from Fig. 8c It is clear that even with manufacturing tolerances on the product carrier 40, the adapter 50 or the contact rail 30, a secure electrical connection is realized by the connector, since in the insertion, the transverse direction 82, aligned pin contact 55 on a direction of vertical direction 82 extending wide contact surface 35 hits. Since the conductor 33 extends in the longitudinal direction 80, the contacting can be made at any point in the longitudinal direction 80 of the holding profile 20. The conductor 33 is a metal band. By a nickel plating it is protected against corrosion. In the case of the contact 56 provided on the underside of the adapter 50, a faulty connection is likewise excluded, since here too the conductor track 34 provided on the holding profile 20 extends over the entire longitudinal extension of the holding profile 20 and the contact 56 has a sufficiently wide, substantially horizontally inserted adapter extending contact surface 36 offers. This conductor 34 is an S-shaped bent metal strip, wherein only the lower portion of the conductor 34 is held by means of holding means 38, 38 'on the contact rail 30 and thus on the holding profile 20. The upper portion of the conductor 34 is exposed and is thus designed to be resilient, with the inserted adapter 50, 50 ', the conductor 34 is pressed down, in a horizontal orientation. The then upwardly acting spring force causes a secure contact with the contact 56. In the Fig. 8b and 8c For example, the upper portion of the trace 34 is shown in a relaxed state to illustrate that the trace 34 can in each case reach the contact 56 for contacting.

The inventive device for displaying goods 10 can be used for various applications. A particular advantage is the ease of use and safe installation. There is no need for specialized personnel for the construction of such a device 10 and changing the goods carrier 40, 40 'is easy by pulling out and pushing the Carrier 40, 40 'possible, this process is self-explanatory. Is a goods carrier 40, 40 'after installation the wrong way round, ie pushed with the bottom up in the holding section 20, no contact is made. The product carrier 40, 40 'can then be easily pulled out again and connected in the correct orientation with the holding profile 20. By using the low-current conductor tracks, the energy consumption for the consumers 42 of the product carriers 40, 40 'is low. By providing larger devices 10 with multiple lighting units on the product carriers 40, 40 'may even be saved energy for the ceiling lighting.
