SECURITY CANOPY FOR FILING CABINET DRAWER I Filed Sept. '16, 1960 IN VENTOR Ric hard W. A rmsTro-ng BY wmmzq ATTORNEY United tates 3,041,124 SECURITY CANOPY FOR FILWG CABINET DRAWER Richard W. Armstrong, S. Glen Road, Potomac Rte. 1, Rockville, Md. Filed Sept. 16, 1960, Ser. No. 56,609 1 Claim. (Cl. 312270) My invention relates to a security tiling cabinet provided with means for determining whether there has been an unauthorized attempt to enter the cabinet.
With this object in View, I provide a canopy covering the open portion of a filing cabinet drawer which will pull out with the drawer to disclose physical damage of a burglarious attempt but will roll back into the cabinet only after the drawer is fully open, thus afiording normal access to the drawer contents.
Referring to the drawing for a more complete disclosure of the invention: FIGURE 1 is a fragmentary perspective view of a file cabinet with an opened drawer and the canopy covering the open portion of the drawer; FIGURE 2 is a section on the line 2-2 of FIGURE 1; FIGURE 3 is a section on the line '3-3 of FIGURE 2; and FIGURE 4 is a fragmentary perspective view of a detail.
The cabinet 1 is a conventional metal cabinet provided with sliding drawers 2 mounted in the cabinet, with the conventional drawer suspension 3 carried by the vertical walls of the cabinet and consisting of telescoping slides 4 and 5, the latter supporting the drawer 2 with roller bearings 6 therebetween.
For suspending the canopy 18 on the drawer 2, an angle iron track 7 is secured to each side of the drawer 2 and rollers 8 are revolubly mounted on the canopy to roll on the tracks 7. On each side of the canopy, a latch 9 is mounted on a pivot 10 which latter is secured to the side of the canopy. A tension spring 11 is secured to the latch 9 at one end and at the other end to a bracket 12 secured to the canopy wall. Secured to each inner side of the cabinet walls near the front of the cabinet is a stop 13 for tripping the latch 9. In each track 7 near its inner end is a cut away opening that forms a keeper ice 14 with which the end of the latch 9 engages, to lock the canopy to the track 7 which is secured to the canopy. When the canopy is in position completely covering the drawer and the drawer is in closed position, latch 9 engages the opening of the keeper 14 in the track 7 and the drawer and canopy move as a unit as the drawer is pulled out from its closed position to open position. As the drawer reaches its fully open position, the latch 9 engages the stop 13 on the cabinet to turn the :latch on its pivot 10 and lift the latch out of engagement with the keeper 14 against the tension of the spring 11. Upon rolling the canopy back into the cabinet and while the drawer is open, the latch will override the opening of the keeper 14 and permit the canopy to roll back into the cabinet. On withdrawing the canopy to cover the open drawer or closing the drawer, the latch 9 will reengage the keeper.
To hold the back of the canopy when it is pushed back into the cabinet to clear the drawer, there is provided a track 15 secured to the sidewall of the cabinet and on which the rear wheel 8 of the canopy runs, the front wheel 8 remaining on the track 7.
A security cabinet, a sliding drawer in the cabinet, telescoping slides between the drawer and the cabinet, a canopy carried by the drawer, tracks carried by the drawer, rollers carried by the canopy to roll on the tracks, a spring latch carried by the canopy, a stop on the cabinet for tripping the latch, a keeper on the track with which the latch engages to lock the canopy to the track; when the canopy covers the drawer and the drawer is in closed position, the latch engages the keeper and the drawer and canopy move as a unit from closed to open position; when the drawer is fully open, the latch engages the stop on the cabinet to lift the latch out of engagement with the keeper; when the canopy is rolled back into the cabinet and the drawer is open, the latch will override the opening in the keeper and permit the canopy to roll back into the cabinet.
