Patent attributes
Disclosed are discrete gravity feed merchandise-advancement seats for use on a shelf support. The seats have a width having two sides and a length, a merchandise-advancement mechanism retention element disposed on each side along the length, and a merchandise-advancement mechanism disposed in retention elements. A driver is disposed in combination with the seat. A guide channel on each side of the driver surrounds the two retention elements so that the driver can traverse the length of the seat, and provide vertical and horizontal stability to the driver. The seats may have attachment mechanisms on front and rear edges that attach to mating attachment mechanisms proximal the front and rear of the shelf support. Dividers cooperate with the seats to provide merchandise display channels. Attachment mechanisms disposed proximal the front and rear of the shelf support allow for adjustable lateral placement of the seats and dividers.
