- the sprocket 50 and sprocket washers 76, 78 are molded into a single piece from nylon or other suitable material.
- the shelf frame 25 slides along the extender arm 40 and an extender arm 72.
- first sprocket 50 and second sprocket 49 that engage slots on the cross rails 24, 26 eliminates "racking" and binding when a shelf frame 25 is moved in or out.
- the teeth of the sprockets engage slots on the cross rails 24, 26 and insure that a pulling or pushing force is evenly applied such that the shelf frame 25 slides in a perpendicular direction to the upright 30 or the back wall 31.
- FIGURE 3 which shows a side elevational view of the shelf assembly of FIGURE 2
- a mounting bracket 90 attaches the internal rack arm 40 to the slotted upright (not shown).
- the sprocket washer 76 helps to couple the sprocket 50 to the axle 52.
- FIGURE 3 also illustrates details of a position locking mechanism or locking lever 100 that prevents the shelf frame 25 from sliding along the extender arms 40, 72.
- the position locking mechanism 100 includes a tab 102 and extends from the tab 102 to an extension 104 that fits into one of the slots, for example slot 103, on the arm 40.
- the position locking mechanism 100 is affixed to the side rail 24 by a bolt 106 and washer (not shown) and is rotatable in the direction indicated by arrows 108, 110 about the bolt 106.
- the extension 104 is biased, for example by piece of steel (not shown) to extend into the slot 103, preventing the arm 40 from moving forward or backward, thus preventing the shelf frame 25 from sliding along the arm 40.
- a user depresses the tab 102 by applying force with a finger in the direction indicated by the arrow 114.
- the position locking mechanism 100 rotates about the axis defined by the bolt 106, and the extension 104 slides out of the slot 103, as is shown in FIGURE 4.
- the position locking mechanism 100 engages the same slots that the sprocket 50 engages, resulting in multiple locking positions of the shelf frame 25.
- the shelf frame 25 may be locked at each position that a tooth of the sprocket 49, 50 engage the respective slots in the side rails 26, 24.
- the invention requires only a single position locking mechanism 100.
- the position locking mechanism 100 is only required along one of the side rails 24, 26.
- the single position locking mechanism is only located along the side rail 24, and not along the side rail 26, although the position locking mechanism 100 could also be employed along only the side rail 26 and not along the side rail 24. This implementation reduces the cost of a locking slidable shelf frame.
- FIGURE 4 depicts the position locking mechanism 100 in the released position such that the side rail 24 can slide along the arm 40.
- FIGURE 4 also depicts other alternative forms of the invention including a rotatable mounting bracket 120. Additionally, a stopping device, such as a bolt or other removable barrier 122 and nut (not shown) combination is in a different location than the bolt 106 and nut combination of FIGURE 3.

- the position locking mechanism 100 is preferably made of 14 gauge steel .
- the position locking mechanism 100 includes a plate 101 and the extension 104 that extends into a slot, for example slot 111 of the arm 40.
- the extension 104 is maintained within the slot 111 by a biasing apparatus, as shown in FIGURE 13, preferably a soft metal piece 113 that is affixed by a bolt 115 and nut 117 to an inner wall 119 of the rail 24.
- the metal piece 113 applies a force in the direction indicated by arrow 125, pushing the extension 104 into the slot 111.
- FIGURE 13 also illustrates a top wall 121 and outer wall 123 of the rail 24.
- the extension 104 moves downward in the direction indicated by the arrow 146, disengaging the slot of the arm 40.
- the extension 104 moves in the direction opposite the arrow 125 so that the extension 104 no longer engages the slot 111 in the arm 40.
- the rail 24 may freely slide along the arm 40.
- the surface 144 preferably includes a thin layer of a soft spongy material for improved feel and control when the surface is touched by a finger.
- the invention preferably includes a single position locking mechanism 100 in the shelf assembly 20 to allow for one- handed release of the lever and one handed sliding of the shelf frame 25 along the arms 40, 72.
- Two release levers may be employed, for example, to reduce the possibility of accidental unlocking of the position locking mechanism.
