A tiered display unit includes a frame assembly. The frame assembly includes a first side support structure having a plurality of support members that form at least one tier, a second side support structure having a plurality of support members that form at least one tier and a plurality of cross members that connect the first support structure to the second support structure. Select cross members of the plurality of cross members include a pair of elongated components that are spaced apart from each other and occupy an area that is the same as the non-selected cross members. The space between the pairs of elongated components of the select cross members are configured to receive hooks for mating display accessories to the frame assembly.

A method for calculating sales trend of a product at a store shelf based on crowdsourcing, includes receiving, by a retail store server, availability data of a product measured on a shelf in the retail store from a portable device, where the availability data is in the form of a picture acquired of the product on the shelf, identifying products on the shelf using tags attached to the shelves, calculating sales velocity and sales trends of the product from the identified products, and transmitting the sales velocity and sales trend of the product to one or more third parties' systems in a supply chain of said retail store. Products and their locations on retail store shelves have been cataloged in a product database.

A mounting device (10) for connecting two support beams (20, 30, 40) of a rack has an attachment plate (11). The attachment plate (11) has a through-hole (14) arrangeable adjacent an opening (21) of a first (20) of the two support beams and at least one first engaging element (12) for engaging with a recess (31, 32) of a second (30; 40) of the two support beams when the attachment plate (11) is arranged with a first flat side (11C) facing the first support beam (20). The mounting device (10) further has an eccentric stud (15) insertable into the through-hole (14) of the attachment plate (11) and the opening (21) of the first support beam (20). Therein, turning the eccentric stud (15) adjusts a position of the first engaging element (12) in the recess (31, 32) of the second support beam (30; 40).

A display panel that has a first edge of a predetermined length that includes a first mating element at a predetermined location along the predetermined length; a second edge of a second predetermined length that includes a second mating element that is complementary to the first mating element and is located along the second predetermined length at a position that is complementary to the predetermined location of the first mating element; a third edge that is connected to the first and second edges and spaces the first and second edges apart by a predetermined distance; and, a fourth edge that is connected to the first and second edges and spaces the first and second edges apart by a predetermined distance and defines an opening for inserting a product into a display area.

A display system for coupling to visual communication products has a frame and a display surface, wherein the display system presents a coupling device for coupling to the frame, associated with an accessory that can be manually coupled and decoupled, defining a support. For this purpose, the coupling device presents a flattened body, of a length according to the thickness of the frame, having an end front flange which determines an elbow, and which defines an insertion groove in the profile of the frame, having at its opposite end an elastically deformable rear clipping flange. In this way, the coupling device presents on its front side edge an opening defined by a semi-sphere acting as a positioning pin where the accessory is coupled.

An apparatus includes a shelf having a front edge, a solar cell circuit disposed at the front edge, a display screen, and a controller operatively coupled to the solar cell circuit and the display screen. The controller monitors the period of a waveform of a charging voltage of a storage capacitor of the solar cell circuit, displays an image on the display screen in response to a change in the waveform timing. A system includes a plurality of shelves each having a front edge, a solar cell circuit disposed at the front edge of each of the plurality of shelves, and a controller operatively coupled to the solar cell circuits. The controller monitors the frequency at which a power transfer of each solar cell circuit occurs, and signals a device in response to a change in the frequency at which the power transfer occurs.

Apparatus firmly holds and protects an ESL (Electronic Shelf Label) assembly (ESL attached to a basket clip) installed onto a retail basket wire member so that the ESL assembly is prevented from being dislocated off the wire member by impact or disturbance. Apparatus confines the ESL assembly on a retail basket wire member with a rear lip engaged behind the rear portion of the basket clip, and a front face that engages with the front face of the ESL. A bottom tongue engages with the bottom edge of the ESL to immobilize apparatus on ESL assembly. Apparatus has two protruding shoulders or a friction coating to prevent horizontal dislocation of apparatus off ESL assembly. Another embodiment of apparatus in the form of a strip is adapted to engage with a plurality of ESL assemblies. Apparatus has holes so it can be additionally immobilized onto the wire member with fasteners.

A shelving system for replenishing a stock of a product. The shelving system uses gondolas each having a base, a support structure coupled to the base, and a shelf coupled to the support structure. The system has a first configuration that provides access to the front of the shelf but not to the back of the shelf. The system has a second configuration that provides access to the back of the shelf so as to enable replenishment of the stock by adding additional product from the back of the shelf.

A shelf edge system and/or light box system which can be easily and conveniently attached to an existing shelf system, and which has a display system capable of attracting the attention of shoppers in a store.
