DETAILED DESCRIPTION


FIG. 1 is a perspective view of a display unit 100 according to one embodiment of the disclosure. The display unit 100 includes a base 104. The base 104 includes a top surface 122, a front surface 124, a bottom edge 126, and a back surface 128, forming a substantially box shape structure.


A bristle floor 102 is disposed on a top surface 122 of the base 104. The bristle floor 102 includes a plurality of tightly-spaced bristles, preferably arranged in a matrix. Each bristle is an elongated resilient and flexible protrusion with an amount of rigidity. The bristle includes a rounded top end. As a result of the arrangement of the bristles, spaces are provided therebetween. These spaces or voids of the bristle floor 102 are configured to receive mating protrusions of other accessories of the universal merchandising system 100, e.g., a divider 410, a stopper 450, a multi-floor assembly 500, a visual display board 600, and/or a shelf assembly 700, shown in figures to be discussed further below.


The bristle floor 102 provides a flexible attachment mechanism for other accessories to be easily and releasably secured onto the universal merchandising system 100. For example, a divider 410 (see FIG. 4) may include a plurality of lower protrusions that engage spaces in the bristle floor 102. The divider 410 can be secured to any location on the bristle floors 102 by inserting the protrusions of the divider 410, such as by press-fit, into the spaces of the bristle floor 102. The divider 410, as well as any other accessory, can be easily detached and reinserted into a different location on the bristle floor 102 as needed. Thus, the bristle floor 102 provides a customizable attachment mechanism to the accessories such that customized display spaces are configured to accommodate the different sizes, shapes, heights, display sequences of the merchandise to be displayed.


The display unit 100 includes a back wall 106. A section of dividers or “binning” 108 is disposed at a top portion of the back wall 106. The binning can be configured as dividing slots configured to receive and secure an upper portion or side edge of an accessory. For example, the binning 108 can receive an upper portion of the divider 410, such that the upper portion of the divider 410 is secured to the display. In one embodiment, the bristle floor 102 secures a lower portion of an accessory and the binning 108 secures an upper portion of the accessory; in this manner, the bristle floor 102 and the binning 108 together secure the accessory on the display unit 100. In FIG. 1, for example, three sections of back wall 106 are employed, but more can be utilized as needed for a larger display. For any given display arrangement, the sections as arranged together will also be referred to collectively as the “back wall 106”. The use of sections allows for flexibility in the size of the overall display.


The front surface of the back wall 106 may include various indicia, e.g., pictures, graphs, symbols, texts, for any appropriate purposes. For example, the back wall 106 may include text and symbols as assembling instructions of the display unit 100. In another example, the back wall 106 may include a picture that highlights the merchandise to be displayed.


The base 104 includes two side panels 110 disposed on two ends (left and right) of the base. The side panels may include a carve out to serve as a handle 111. The side panel 110 may include any indicia, e.g., e.g., pictures, graphs, symbols, texts, for any appropriate purposes.
