The tray may include a notch for accessing the merchandising product from below and the product management display system may be thin to minimize vertical height. The trays may also be engaged with the shelf and may be, locked and unlocked. ## Claims ### Claim 1 A merchandise display system comprising: a tray configured to be secured to a support structure, wherein the tray includes a forward end and a rearward end; the tray includes at least one divider wall and a floor, the divider wall extending upwardly from the floor; a pusher mechanism comprising a biasing device and configured to slide along a top surface of the floor to move a product toward the forward end, the pusher further comprising: a pusher paddle having a pusher face and having an aperture in a lower portion; a pusher floor engaged with the pusher paddle, the pusher floor extending backward from the pusher paddle; wherein the biasing device is a coil spring and wherein the coil spring is configured to pass through the aperture in the pusher paddle; wherein the pusher floor does not extend forward of the pusher face; a product retaining member configured to be positioned proximate the forward end of the tray such that the product positioned on the top surface of the floor contacts the product retaining member when the product moves toward the forward end of the tray; and a rear lock system configured to lock the pusher paddle proximate the rearward end of the tray, the rear lock system comprises: a locking wall extending upward from the pusher floor, the locking wall having a ridge; a bar engaged with a rear portion of the tray; wherein the ridge is configured to engage the bar to retain the pusher mechanism proximate a rearward end of the tray, and wherein a vertical height of the locking wall is less than a vertical height of the bar such that a rearward end of the pusher floor does not contact the floor of the tray when the pusher mechanism is in a locked position; wherein the forward end of the tray includes a notch and wherein the notch divides the product retaining member into a first product retaining member on a first side of the notch and a second product retaining member on a second side of the notch. ### Claim 2 (depends on 1) The merchandise display system of claim 1, wherein a maximum thickness of the floor is less than 0.25 inch. ### Claim 3 (depends on 1) The merchandise display system of claim 1, wherein a maximum thickness of the floor is less than 0.125 inch. ### Claim 4 (depends on 1) The merchandise display system of claim 1, further comprising an engagement wall extending downward from the tray, and wherein the engagement wall is configured to engage a channel connected to the support structure. ### Claim 5 (depends on 4) The merchandise display system of claim 4, further comprising a locking system configured to lockably engage the merchandise display system to the support structure. ### Claim 6 (depends on 5) The merchandise display system of claim 5, wherein the locking system comprises: an intermediate wall extending downward from the tray in a position forward of the engagement wall, the intermediate wall including at least one aperture; a lock lever having a bottom wall, a vertical wall and a locking pin, the lock lever rotatably engaged with the merchandise display system; wherein the locking pin is configured to extend through the at least one aperture in a locked position to lockably engage the merchandise display system to the support structure. ### Claim 7 (depends on 5) The merchandise display system of claim 5, wherein the locking system comprises: at least one swing arm rotatably engaged with a back portion of the merchandise display system and configured to extend below the floor of the tray in a locked position; wherein the at least one swing arm is configured to extend behind a shelf of the support structure in a locked position to lockably engage the merchandise display system to the support structure. ### Claim 8 A merchandise display system comprising: a tray secured to a support structure, wherein the tray includes a forward end and a rearward end; the tray includes at least one divider wall and a floor, the divider wall extending upwardly from the floor; a pusher mechanism comprising a biasing device and configured to slide along a top surface of the floor to move a product toward the forward end; a product retaining member configured to be positioned proximate the forward end of the tray such that the product positioned on the top surface of the floor contacts the product retaining member when the product moves toward the forward end of the tray; and an engagement wall extending downward from the tray, and wherein the engagement wall engages a channel connected to the support structure; a locking system comprising: an intermediate wall extending downward from the tray in a position forward of the engagement wall, the intermediate wall including at least one aperture; a lock lever having a bottom wall, a vertical wall and a locking pin, the lock lever rotatably engaged with the merchandise display system; wherein the locking pin is configured to extend through the at least one aperture in a locked position to lockably engage the merchandise display system to the support structure. ### Claim 9 (depends on 8) The merchandise display system of claim 8, wherein the channel is integrally formed with the support structure. ### Claim 10 (depends on 8) The merchandise display system of claim 8, wherein the channel is integrally formed with a shelf extender which is engaged with the support structure. ### Claim 11 (depends on 8) The merchandise display system of claim 8, wherein the forward end of the tray includes a notch and wherein the notch divides the product retaining member into a first product retaining member on a first side of the notch and a second product retaining member on a second side of the notch. ### Claim 12 (depends on 8) The merchandise display system of claim 8, wherein the product retaining member extends substantially an entire width of the tray, and wherein the product retaining member has a curved top edge. ### Claim 13 (depends on 8) The merchandise display system of claim 8, wherein a maximum thickness of the floor is less than 0.25 inch. ### Claim 14 (depends on 8) The merchandise display system of claim 8, wherein a maximum thickness of the floor is less than 0.125 inch. ### Claim 15 (depends on 8) The merchandise display system of claim 8, wherein the pusher mechanism further comprises: a pusher paddle having a pusher face and having an aperture in a lower portion; a pusher floor engaged with the pusher paddle, the pusher floor extending backward from the pusher paddle; wherein the biasing device is a coil spring and wherein the coil spring is configured to pass through the aperture in the pusher paddle, and wherein the pusher floor does not extend forward of the pusher face. ### Claim 16 (depends on 15) The merchandise display system of claim 15, further comprising a rear lock system configured to lock the pusher paddle proximate the rearward end of the tray. ### Claim 17 (depends on 16) The merchandise display system of claim 16 wherein the rear lock system comprises: a locking wall extending upward from the pusher floor, the locking wall having a ridge; a bar engaged with a rear portion of the tray; wherein the ridge is configured to engage the bar to retain the pusher mechanism proximate a rearward end of the tray, and wherein a vertical height of the locking wall is less than a vertical height of the bar such that a rearward end of the pusher floor does not contact the floor of the tray when the pusher mechanism is in a locked position. ### Claim 18 (depends on 8) The merchandise display system of claim 8, further comprising a side lock system configured to engage an adjacent second merchandise display system.
