A detent on the drawer and a latch bar on the stationary frame; a latch bar lifting cam on the drawer and lifting the bar off the detent when the drawer is pressed inwardly, the cam tipping to conceal the detent and guide the bar over the detent as the drawer is released and urged outwardly under spring pressure, the drawer having an upwardly tilting cassette pocket tipped upward by the outward spring pressed thrust of the drawer.
4 Claims, 2 Drawing Figures PAIENTEDSEP 1 7191 4 SHEET 2 BF 2 CASSETTE DRAWER UNIT WITH LATCH BRIEF SUMMARY OF THE INVENTION The invention relates to drawer units and has special reference to the storage of tape cassettes and film cassettes.
The problem forming the basis of the invention is to provide a simple to handle drawer unit, for example for tape cassettes and film cassettes, which enables a quick and easy insertion and removal of individual cassettes.
According to the-invention a drawer unit includes a drawer, a frame in which the drawer is movable between a closed position and an open position, biasing means resiliently biasing the drawer toward the open position, and a catch mechanism arranged to retain the drawer in the closed position, but to release the drawer from the closed position in response to an initial movement of the drawer directed away from the open position.
In a preferred arrangement the catch mechanism includes a detent, a locking member engageable in the detent when the drawer is in the closed position, and a cam so arranged that during the said initial movement the cam moves the locking member out of the detent and during movement of the drawer toward the open position the cam prevents the locking member from returning to the detent. Preferably the detent is provided on the drawer, the locking member is mounted on the frame, and the cam is mounted on the drawer.
Preferably also the locking member is generally U- shaped, one leg of the U-shape being pivotally mounted on the frame and the other leg being arranged to engage the detent. In a preferred arrangement the cam is pivotally mounted.
The drawer may include a receiving pocket for a tape or film cassette, the receiving pocket being arranged to be partly ejected automatically from the drawer as the drawer is moved into the open position. Preferably the receiving pocket is pivotally mounted in the drawer and is provided with a surface arranged to engage the frame as the drawer is moved to the open position and to cause rotation of the pocket.
By way of example, one embodiment of the invention is described in detail with reference to the drawings of which:
FIG. 1 is a sectional side elevation of a storage rack with several drawer units arranged one above the other, and
FIG. 2 is a front elevation of a rack having 32 drawers.
DETAILED DESCRIPTION OF THE INVENTION In FIG. 1 is shown part of a rack 2 with a number of drawer compartments arranged next to and above each other for receiving a corresponding number of drawers 1 for the storage of cassettes 10. Three drawers appear in FIG. 1.
The lowest drawer 1 contains a cassette and is shown in its closed position with the front wall 11 of the drawer flush with the front of the rack 2. The drawer 1 has toward its rear an extension flange 8a with an upstanding locking projection 8, the front edge or face 8b of which forms one wall of a detent. On the rear wall 2a of the rack 2 is pivotally mounted a U-shaped locking lever 3 which can engage the edge 8b of projection 8 and which is biased downwardly in a clockwise direction (as seen in FIG. 1) by a tension spring 8c anchored to the rear wall of the rack. Clockwise movement of the locking lever 3 is limited by an L-shaped support 3a which is affixed on frame rail 2b of the rack. In the position illustrated by the lowest drawer, the lever 3 rests in the detent in front of the projection 8 to confront edge 8b and the drawer 1 securely closed.
If a drawer 1 is to be opened for inserting or removing a cassette, it is gently pushed a little way into the drawer compartment so that the locking lever 3 rides up and over the rear sloping edge 4a of a swivel cam 4 pivoted to flange 8a in front of the projection 8. Then pressure on the drawer is released so that, as illustrated by the uppermost drawer in FIG. 1, the spring 5 moves the drawer outwardly, causing the locking lever 3 to tip cam 4 in a rearward direction and then ride up the front faces 4b of the tilted cam 4, the front face 4b of the cam being long enough to enable the lever 3 to clear the projection 8 and release the drawer. The cam 4 has lower edges 40, 4d oriented obliquely of each other and confronting the horizontal lip 8e of flange 8a. The edges 40, 4d alternately engage lip 8e as the cam is tipped to limit the swinging or tilting of the cam 4 in the alternate positionsof the cam.
At all times the drawers are biased toward the open position by one or a pair of prestressed compression springs 5 which are arranged under each drawer on a rod 5a and which bear against a slide hearing In which is affixed to the underside of the drawer.
For receiving and storing cassettes there is in each drawer a separate receiving pocket 6 (see middle drawer) having on its rear wall an upwardly projecting stop bar 7 which meets with a stop surface 9 in the rack approximately 10-15 mm. before reaching its end position, whereby the receiving pocket 6 is tilted into an upward inclining position enabling easy access to the cassette 10 as illustrated at the middle drawer of FIG. 1.
When the occasion arises, the cassette 10 is reinserted in the receiving pocket 6, and the drawer I pushed into the respective drawer compartment in the rack 2 until its front side 11 is flush with the front side 12 of the rack 2. As the drawer is pushed inwardly, the rear facing oblique camming edge or face 8d of projection 8 engages and lifts the locking lever 3 off support 3a. Lever 3 passes over the projection 8 and engages and tips the cam 4 forwardly. Subsequently, the locking lever 3 drops into the detent in front of the projection 8, simultaneously pushing the swivel cam 4 back again into its normal position as shown by the lowest drawer. The drawer is automatically held in this position.
The rack shown in FIG. 2 is illustrative of the way in which drawer units in accordance with the invention may be arranged in a convenient manner for storage of large numbers of articles such as tape or film cassettes.
