Abstract
A self-closing door assembly for limiting access to goods displayed on a shelving system. A frame assembly is attached to the shelving system adjacent the front edge of a first shelf, with upper and lower guide rails to slidably engage a pair of overlapping and self-closing doors. The door are aligned to laterally slide open from a closed position at which they interfere with manual access to the goods displayed on the shelf. Springs disposed between the frame assembly and the doors urge the doors toward the closed position. The doors are adapted for manual engagement to be urged toward the open position, and the springs automatically return the doors to the closed position upon manual release thereof.
Claims18
A self-closing door assembly for limiting access to goods in a shelving system that includes a first shelf and a second shelf for displaying the goods, the first shelf having a front edge, the assembly comprising:
- a frame assembly adapted for fixed attachment to the shelving system adjacent the front edge of the first shelf;
- a guide rail assembly including a lower guide rail positioned in fixed relationship to said frame assembly and aligned substantially in parallel with the front edge of the first shelf, and an upper guide rail located above said first guide rail;
- a first door that includes a first lower door portion and a first upper door portion attached to one another in height adjustable fashion to enable adjustment of said first door height according to the shelving system shelf spacing between the first shelf and the second shelf, and that is aligned to laterally engage said guide rail assembly to thereby slide between a closed position that interferes with manual access to the goods displayed on the first shelf and an open position that enables manual access to a first fractional portion of the goods displayed on the first shelf, the first lower door portion and the first upper door portion including a first row of holes and a first vertically oriented, elongated slot spaced from the first row of holes, with a first fastener disposed through at least one hole in the first row of holes, and a second fastener disposed through the first elongated slot to fix the first lower door portion and the first upper door portion at a selected first door height;
- a second door that includes a second lower door portion and a second upper door portion attached to one another in height adjustable fashion to enable adjustment of said second door height according to the shelving system shelf spacing, and aligned to laterally engage said guide rail assembly to thereby slide between a closed position that interferes with manual access to the goods displayed on the first shelf and an open position that enables manual access to a second fractional portion of the goods displayed on the first shelf, the second lower door portion and the second upper door portion including a second row of holes and a second vertically oriented, elongated slot spaced from the second row of holes, with a third fastener disposed through at least one hole in the second row of holes, and a fourth fastener disposed through the second elongated slot to fix the second lower door portion and the second upper door portion at a selected second door height, said first door and said second door arranged in left-right opposing orientation;
- a first constant-force spring retained in position by said frame assembly, and having an end clip extended to engage said first door to urge said first door toward said closed position;
- a second constant-force spring retained in position by said frame assembly, and having an end clip extended to engage said second door to urge said second door toward said closed position,
- wherein said first door and said second door are adapted for manual engagement to be urged toward said open positions, and wherein said first and second springs return said first and second doors, respectively, toward said closed positions upon manual release thereof;
- first and second end panels fixed to left and right sides of said frame assembly, respectively, each extending rearwardly to limit access to goods upon the first shelf from left and right sides thereof;
- a first telescopic side frame that is height adjustable to accommodate the selected first door height of said first lower door portion attached to said first upper door portion, and
- a second telescopic side frame that is height adjustable to accommodate the selected second door height of said second lower door portion attached to said second upper door portion,
- wherein the first constant-force spring winds in a first coil that is disposed laterally beyond a first end of the first door in the closed position,
- wherein the second constant-force spring winds in a second coil that is disposed laterally beyond a second end of the second door in the closed position,
- wherein the first door and the second door are disposed between and move between the first coil and the second coil in transitioning from the respective closed position to the open position.

- a frame assembly adapted for fixed attachment to the shelving system adjacent the front edge of the first shelf, the frame assembly including a first vertical frame defining an internal compartment and an opening;
- a guide rail assembly positioned in fixed relationship to said frame assembly and aligned substantially in parallel with the front edge of the first shelf;
- a first door aligned to laterally engage said guide rail assembly to thereby slide between a closed position that interferes with manual access to the goods displayed on the first shelf and an open position that enables manual access to a first fractional portion of the goods displayed on the first shelf;
- a first spring disposed between said frame assembly and said first door to urge said first door toward said closed position,
- wherein said first door is adapted for manual engagement to be urged toward said open position, and said first spring returns said first door to said closed position upon manual release thereof,
