Description

It is already known to attach a drawer lock to office furniture, in which all drawers by a push rod, which is determined, and their Engage the locking ends in the corresponding notches of the drawers, turn closed and when loosening the push rod it is pushed up by a spring and thereby at the same time all drawers are released

ίο the.

From this known, the invention differs in that the known per se inclined drawers mounted on rollers in the pushed-in position

if a push rod is held locked, turn which are under spring pressure in such a way that the locking end when the drawer is pushed in the push rod automatically jumps into the latch of the drawer and prevents it from being closed.

ao slide back secures. The push buttons of the Push rods also all end in a trough that can be closed by a slide of the table frame.

The subject matter of the invention is shown in an exemplary embodiment in the drawing shown, namely shows:

Fig. Ι a section through a desk frame with inserted drawers and the locking device,

Fig. 2 is a side view of this in partial section.

In the desk frame α, the drawers l ·, b \ b ^{2 are} mounted on rollers c , while rollers c ¹ serve to guide the upper edges of the drawer. The push buttons, the locking rods d, d ¹ , d ² all end in a recess k, which can be closed by a slide i . At their other end, the locking rods each have a nose that engages in a recess / of the corresponding drawer in its closed position.

If, for example, the pressure

button linkage d or »a button g embedded in the table top is pressed, the bar moves downwards; here the locking lug e emerges from the recess f of the drawer, b , and the drawer is released so that it can roll out of the table frame. Since the push-button rods are now under spring action, their locking means slide when the

ίο The drawers automatically reinsert themselves into the corresponding notches and hold them in the locked position again. The springs h arranged below the drawers serve to give the subjects the impetus to roll after the locking means have been released and to dampen the shock when they are pushed in. The push buttons g of the release rods are embedded in a recess k which can be closed by means of a slide i or the like and are thus invisible to the uninitiated. For the purpose of further security, the drawers can of course still be made lockable using a common bag lock or the like.
The subject matter of the invention can advantageously be used with all types of furniture with drawers, for example also with card file boxes and the like.
