## Background
BACKGROUND INFORMATION
1. Field
The present disclosure relates generally to product display, and in particular to product display shelves having a spring driven pusher to force product to the front of the display.
2. Background
In retail stores, shelves are necessary for displaying and storing products. When a product is removed from a tray, a gap remains on the tray where the product was stored. Trays that automatically push the product forward are desirable so that a customer is always presented with a product and therefore, does not assume that the product is out of stock, or alternatively have to search for the product.
A number of different types of devices are known for automatically pushing product forward. For example, gravity fed rollers allow certain products to advance so that a product is always present at the front of the display. Another example is a spring driven pusher plate where the spring driven plate advances toward the front of the display as product positioned between the pusher plate and the front of the display is removed.
Although spring driven pusher plates are known, a number of problems arise in the implementation of current spring driven pusher plates. One problem is that springs may break or lose their force and need to be replaced. Replacement of springs may require disassembly of a tray unit in which the pusher plate operates. Another problem with spring driven pusher plates is that the pusher plate must be held to the rear while placing product between the pusher plate and the front of the display. Furthermore, packaged food products may require refrigeration. Cold air sinks to the bottom of a space. Therefore, refrigeration of a display area may be impaired during loading of the trays as removed trays allow cold air to settle to the bottom of the display. Additionally, trays may need to be adjustable to accept products of different widths, and adjusting a tray may cause gaps in levels of the product display that impair refrigeration.
Accordingly, it would be advantageous to have a method and apparatus, which takes into account one or more of the issues discussed above as well as possibly other issues.
SUMMARY
In one illustrative embodiment, a pusher tray assembly comprises a hanging tray and a sliding tray having a wire track, the sliding tray moveably connected to the hanging tray by fins of a pusher, the pusher slidingly engaged to the wire track for movement between a first position and a second position.
In another illustrative embodiment, a pusher tray assembly comprises a hanging tray, a wire track in a sliding tray, the wire track having a plurality of wires, each wire having a first end removably engaged to a front end of the sliding tray and a second end removably engaged to a rear end of the sliding tray. A pusher slidingly engages the sliding tray and the hanging tray for movement between a rear of the sliding tray and a front of the sliding tray and for sliding engagement of the sliding tray to the hanging tray. A left hook extends from a bottom of the pusher and slidingly engages a first wire in the wire track. A right hook extends from the bottom of the pusher and slidingly engages a second wire in the wire track. A left fin extending downward from a bottom of the pusher slidingly engages a center tray track in the hanging tray.

Sliding tray 300 may be slidingly engaged with left tray track 230 of hanging tray 200 by passing left lock 362 through left opening 236 in left tray track 230 so that left post 364 may travel in left tray track 230 while left flange 366 prevents sliding tray 300 from rotating upward beyond left flange 366 when sliding tray 300 is moved from a first position at a rear of hanging tray 200 to a second position in a front of hanging tray 200.
Likewise, sliding tray 300 may be slidingly engaged with right tray track 240 of hanging tray 200 by passing right lock 368 through right opening 246 in right tray track 240 so that right post 370 may travel in right tray track 240 while right flange 372 prevents sliding tray 300 from rotating upward beyond right flange 372 when sliding tray 300 is moved from the first position at a rear of hanging tray 200 to the second position at the front of hanging tray 200.
Left flange 366 may engage second left lock receptacle 234 when sliding tray 300 is in a rear position at a rear of hanging tray 200 and may pass beyond first left lock receptacle 232 when sliding tray 300 is at a front position at a front of hanging tray 200. Right flange 372 may engage second right lock receptacle 244 when sliding tray 300 is in the rear position at the rear of hanging tray 200 and may pass beyond first right lock receptacle 242 when sliding tray 300 is at the front position at a front of hanging tray 200.
In an embodiment, left flange 366 and right flange 372 may be engaged by being pressed downward by second left lock receptacle 234 and second right lock receptacle 244, respectively (see detail of left flange 366 and second left lock receptacle 234 in FIG. 18). When sliding tray 300 is locked in the rear position left stop 382 engages left stop receptacle 383 and right stop 384 engages right stop receptacle 385. Left stop 382 and right stop 384 may be disengaged from left stop receptacle 383 and right stop receptacle 395 respectively by lifting sliding tray upward.
When sliding tray 300 is in the front position, sliding tray is cantilevered out from hanging tray 200 and rotated slightly downward by a weight of sliding tray 300. While rotated slightly downward, right flange 372 prevents rearward movement of sliding tray 300 beyond first right lock receptacle 242 (see detail in FIG. 16). Likewise, when sliding tray 300 is cantilevered out from hanging tray 200 and rotated slightly downward by the weight of sliding tray 300, left flange 366 prevents rearward movement of sliding tray 300 beyond first left lock receptacle 232. A user may lift and rotate sliding tray 300 upward to allow passage of right flange 372 past first right lock receptacle 242 and left flange 366 past first left lock receptacle 232.
Turning to FIG. 8, an illustration of a right front perspective view of the pusher tray assembly with the sliding tray fully extended is depicted. Sliding tray 300 may be pulled in a forward direction away from hanging tray 200. Such movement of sliding tray 300 may be performed in order to load product (not shown) into sliding tray 300. For example, pusher tray assembly 100 may be empty with no product inserted between pusher 400 and front plate 350. Pusher 400 may be pulled forward by spring 500 (see FIG. 13 and FIG. 14) until Pusher 400 is stopped by left fin 450 and right fin 460 contacting a front of edge 222 of center track 220 in a position in close proximity to front plate 350 as shown in FIG. 3 through FIG. 5. FIGS. 15-16 further illustrate operation of left lock 362 and right lock 368 to lock sliding tray 300 in the position in close proximity to front plate 350.
As sliding tray 300 is pulled forward and away from hanging tray 200, left fin 450 and right fin 460 of pusher 400 press against front 222 of center tray track in hanging tray 200 so that pusher 400 remains in position relative to hanging tray 200 but moves to the rear of sliding tray 300 as sliding tray 300 is pulled forward. In the configuration depicted in FIG. 8, pusher tray assembly 100 is ready to have product loaded into sliding tray 300 between pusher 400 and front plate 350. In the extended position of FIG. 8, sliding tray 300 may be locked by left lock 362 and right lock 368 engaging first left lock receptacle 232 and first right lock receptacle 242, respectively (see FIG. 6, FIG. 17, and FIG. 18).
Turning to FIG. 9, an illustration of a right front from below perspective view of a pusher element of the pusher tray assembly is depicted in accordance with an illustrative embodiment. In this view front 412 of plate 410 may be seen with floor 420 extending rearward at approximately a 90 degree angle. Floor 420 may have floor bottom 440 from which left hook 444 and right hook 448 extend downward. Left hook 444 is shown having a curved portion that begins at floor 420 and extends downward to form a semi-circle from which a flat portion extends inwardly and approximately parallel to floor 420 forming a partially enclosed space into which a wire such as first wire 312 may be enclosed. Right hook 448 is shown having a curved portion that begins at floor 420 and extends downward to form a semi-circle from which a flat portion extends inwardly and approximately parallel to floor 420 forming a partially enclosed space into which a wire such as fourth wire 318 may be enclosed.
Floor 420 may have left fin 450 and right fin 460 extending downward at approximately 90 degree angle to floor bottom 440. Left fin 450 may have left fin flange 452 extending outwardly from left fin 450 at approximately an 83 degree angle. Right fin 460 may have right fin flange 462 extending outwardly from right fin 460 at approximately an 83 degree angle. Sliding tray 300 may be moveably connected to hanging tray 200 by left fin 450 and right fin 460. In an embodiment, a user may manipulate left fin 450 and right fin 460 in order to insert left fin 450 and right fin 460 into center track 220 of hanging tray 200. In an embodiment, left fin 450 and right fin 460 may be made from a material having some plasticity or flexibility and may be bent slightly for insertion through center track 220. In another embodiment, left fin 450 and right fin 460 may be manipulated without flexing left fin 450 or right fin 460. Once right fin flange 462 and left fin flange 452 are positioned below tray 210 of hanging tray 200, pusher 400 may travel guided by center track 220. Movement of pusher 400 out of center track 200 is prevented by right fin flange 462 and left fin flange 452 and sliding tray 300 is moveably connected to hanging tray 200. Once left fin 450 and right fin 460 are moveably engaged with tray 210 of hanging tray 200, left hook 444 may be engaged to a wire such as first wire 312 and right hook 448 may be engaged to a wire such as fourth wire 318. In an embodiment, engagement of left hook 444 and right hook 448 may be performed by manually flexing a wire such a first wire 312 or fourth wire 318 to allow engagement of left hook 444 or right hook 448. In an embodiment, an 83 degree upward angle from vertical of right fin flange 462 and left fin flange 452 facilitates manipulation of right fin 460 and left fin 450 through center track 220 of tray 210. In an embodiment, an 83 degree upward angle from vertical of right fin flange 462 and left fin flange 452 provides additional resistance to pusher 400 being pulled out of center track 220. Persons skilled in the art recognize and take into account that a number of angles may be used in conjunction with right fin flange 462 and left fin flange 452.
Turning to FIG. 10, a left rear from above perspective view of the pusher of the pusher tray assembly is depicted in accordance with an illustrative embodiment. Pusher 400 has back 414 of plate 410.

In the view of FIG. 14, spring is engaged but is not yet positioned in compartment 470 (see FIG. 9 through FIG. 11) for engagement with back 414 of plate 410 of pusher 400. Band 520 may be extended and passed under pusher 400 so that coil 512 may be positioned.
Turning to FIG. 15, an illustration of a view along cut line 13 in FIG. 3 of the pusher tray assembly in an open position is depicted. The position of sliding tray 300 to hanging tray 200 in FIG. 15 corresponds to the position of sliding tray 300 to hanging tray 200 in FIG. 8. Left lock 362 engages first left lock receptacle 232. In an embodiment, when sliding tray 200 is locked by left lock 362 and right lock 368 engaging first left lock receptacle 232 and first right lock receptacle 242, respectively, sliding tray 300 hangs at an angle relative to hanging tray 200. The angle is formed by left post 364 of left lock 362 and right post 370 of right lock 368, respectively. Further, a weight of sliding tray 300 causes sliding tray 300 to rotate downward to a cantilevered position over hanging tray 200 and may be stopped at least in part by left flange 366 of left lock 362 and right flange 372 of right lock 368. A user may unlock sliding tray 200 from the position described above by rotating sliding tray 200 upward to a plane parallel to or above a plane of hanging tray 200 and pushing sliding tray 300 toward bracket 260 of hanging tray 200.
Turning to FIG. 16, an illustration of a detail view of left lock with first left lock receptacle when pusher tray assembly is in an open position is depicted. Left lock 362 may be seen engaged with left lock receptacle 232. When sliding tray 200 is rotated upward, left flange 366 will move downward on left post to a position below left lock receptacle 232. Once left flange 366 moves to a position below left lock receptacle 232, sliding tray 300 may be moved toward bracket 260 of hanging tray 200.
Turning to FIG. 17, an illustration of a view along cut line 13 in FIG. 3 of the pusher tray assembly in a closed position is depicted. In an embodiment depicted in FIG. 17, sliding tray 300 has been moved back toward bracket 260 of hanging tray 200 until left lock 362 engages second left lock receptacle 234 and right lock 368 (see FIG. 7) engages second right lock receptacle 244 (see FIG. 7). Right lock 368 engages second right lock receptacle 244 in a similar manner to an engagement of left lock 362 and second left lock receptacle 234.
FIG. 18 is an illustration of a detail view of left lock engaging second left lock receptacle when pusher tray assembly is in the closed position. Left flange 366 at end of left post 364 of left lock 362 is pressed downward by second left lock receptacle keeping sliding tray 200 in a plane substantially parallel to a plane of hanging tray 300. A user may unlock sliding tray 300 from hanging tray 200 by lifting up and rotating sliding tray 300 in substantially vertical direction. Lifting up and rotating sliding tray 300 in a substantially vertical direction releases left flange 366 from second left lock receptacle. Likewise lifting up and rotating sliding tray 300 in substantially vertical direction releases right lock 368 from second right lock receptacle 244 (see FIG. 7). Movement of right lock 368 to release from second right lock receptacle 244, mirrors the movement of left lock 362 to release from second left lock receptacle 234.
