The present invention relates generally to a merchandise display with a merchandise display system comprising a power connector assembly.

In many exemplary power/signal systems, there is a problem with providing power to many devices while trying to create good wire management. Additionally, there is a problem with providing power to many devices while creating a dynamic or flexible system that allows for device relocation, addition of devices, and removal of devices for the power/signal systems. Existing solutions provide cable raceways with multiple connection points (outlet strip approach) or power track systems (track lighting approach). Although many conductors for power and signal combinations can be used, the "outlet strip approach" lacks flexibility and expandability for adding or relocating devices. Traditional powered track systems lack easy ways to incorporate many power and signal conductors. Additionally, for each conductor added to the traditional power track systems the connector required to access those conductors grows significantly in complexity and size.

The examples illustrated in Figures 1 to 7 solve the problem with providing power to many devices while trying to create good wire management, and also creating a dynamic or flexible system that allows for device re-location, addition of devices, and removal of devices for the power/signal system. Existing solutions include cable raceways with multiple connection points (outlet strip approach) or powered track systems (track lighting approach). However, these traditional approaches fall short in several ways. Although many conductors for power and signal combinations can be used, the "outlet strip approach" lacks flexibility and expandability for adding or relocating devices. Traditional powered track systems lack easy ways to incorporate many power and signal conductors. Additionally, for each conductor added to the traditional power track systems the connector required to access those conductors grows significantly in complexity and size.

The purpose of the examples illustrated in Figures 1 to 7 is to provide a "break away" connection. Another purpose of the examples illustrated in Figures 1 to 7 is to provide an easy to use power and signal distribution track system. Track lighting is a good example of a powered track system intended for distributing power to many devices, however current track lighting systems do not use magnetic attachment methods and are not intended for distributing more than power for connected devices. These examples are intended to distribute both power while allowing the easy movement and placement of connected devices such as lighting systems for the retail merchandise display systems.

Examples of retail uses for this example are under-shelf or display-case lighting that may require spot lights for product specials. Spot light modules such as the proof of concept prototype could be used to add lighting in a dynamic, modular, and reconfigurable way. Examples of non-retail applications might include systems which use sensor modules that communicate via additional conductors in the configuration or assembly. This type of application would allow for easy customization of the sensor system.

If additional voltages are added to the configuration of products, additional configurations of products that require different voltages could be connected on the same distribution track such that the devices contacts make contact only with the conductors required. In an example, there may be two bus bars and/or conductive plates. In another example, there may be four bus bars and/or conductive plates in order to handle various additional voltages.

Other devices using this distribution track may separate the magnetic connector from the device itself by using a corded magnetic connector. This allows for many types of devices (especially larger devices) to make use of the distribution track. One example might be embedded hardware devices which use the distribution track as a means for getting power and for intercommunications between embedded devices utilizing additional signal conductors.

Another advantage of this example is that the distribution track implementations may incorporate many conductors for power and/or signal and may only grow in size as conductors are added. The additional conductors for power and/or signal may not increase the complexity because the access of one conductor does not interfere with the other conductors as it does in the traditional powered track approach. This characteristic allows the design technique to be scalable for many applications.

LED lighting systems may be utilized with these examples as a low voltage power supply with magnetic connections, and specifically LED lighting systems utilized with a retail merchandise display system. LED lighting systems are disclosed in U.S. Application Serial No. 13/162,076, filed June 16, 2011 and U.S. Application Serial No. 12/955,198, filed November 29, 2010 (granted as U.S Patent No. 8,864,334).

In other embodiments of the present invention, the LED printed circuit board assembly 532 may extend across a portion of the front portion of the tray 540. The LED printed circuit board assembly 532 may be located at various other locations of the merchandise display without departing from this disclosure.

The LED printed circuit board assembly 532 may include various LED light sources 534 to illuminate the merchandise display system. Additionally, the LED printed circuit board assembly 532 may include metal clips 536 or ends. The metal clips may attach or connect to the ends of the LED printed circuit board assembly 532 and the power jack 558 of the contact assembly 552. The connection from the power wire 520 to the power contacts 514 to the contact assembly 552 with the contact 554, the wire harness 556, and the power jack 558, and finally through to the metal clip 536 powers the LEDs 534 on the printed circuit board assembly 532.

As is described and detailed above, any low voltage power source may be powered by an embodiment of the present invention, not just an LED printed circuit board assembly. For example, the connection from the power wire 520 to the power contacts 514 to the contact assembly 552 with the contact 554, the wire harness 556, and the end contact 558, and finally through to the metal clip 536 may power any other low voltage power source. The low voltage power source may include various lighting systems, such as individual LEDs or other such similar low voltage power assemblies for the merchandise display system.

The tray assembly 530 may also include a flip front portion 570 that allows the description and/or labelling of products and/merchandise. The flip front portion 570 may be located towards the front portion of the tray 540. The flip front portion 570 may include a clear lens such that the light from the LEDs 534 may be illuminated through the flip front portion 570. The flip front portion 570 may also flip up and down as required to assist with the merchandise display system.

The reader should understand that the scope of the present invention is defined by the scope of the appended claims. Many variations in the merchandise display may be made from the specific structures described above without departing from the scope of the present invention as defined by the scope of the appended claims.

While the present invention has been described in detail in terms of presently preferred modes of carrying out the present invention, those skilled in the art will appreciate that there are numerous variations and permutations of the above described merchandise display that may fall within the scope of the present invention as defined by the scope of the appended claims.
