Abstract
Abstract A cabinet has drawers mounted for movement in and out of the cabinet to prevent the cabinet from tipping when one or more of those drawers are displaced outside the cabinet while still attached to the cabinet, a stabilizer leg is provided with an interlock. The interlock prevents the drawer from being removed and tipping the cabinet until the stabilizer leg is in place.

Stabilizer leg interlock means for preventing the withdrawal of an insertable device within a cabinet until a cabinet stabilizing leg is placed in an extended and locked support position comprising: (a) a cabinet having a plurality of receiving means for the insertion and withdrawal of removable devices; (b) locking means for engagement with one or more of said removable devices and preventing the withdrawal of respective ones of said removable devices; (c) said cabinet having a base area and being supported on said base; (d) a cabinet stabilizer leg mounted in said cabinet for extension into an operative position for supporting said cabinet from a first location outside said base; (e) interlock means for engagement with said cabinet support means and said locking means to disengage said locking means from their respective devices for withdrawal from said cabinet; and (f) said interlock means, when engaged with said stabilizer leg cabinet support in its said operative position, disengaging said locking means.
Claim 3
Dependent Claim
50 words
The stabilizer leg interlock means of claim 1, wherein, said locking means includes: (g) a plurality of locking means with at least the first of said locking means being engaged with said interlock means and at least a second of said locking means being slaved to said first locking means.
Claim 4
Dependent Claim
40 words
The stabilizer leg interlock means of claim 2, wherein: (h) said locking means includes return means for returning said locking means to its engaged position with said device when said interlock means is disengaged from said stabilizer leg support means.
Claim 5
Dependent Claim
45 words
The stabilizer leg interlock means of claim 3, wherein: (i) said devices are mounted for withdrawal in the direction of said first location outside said base to oppose an upsetting force on said cabinet produced when said cabinets are withdrawn and extend outside said base.

The stabilizer leg interlock means of claim 7, wherein: (o) said support strut has a first and second section connected by a pivoting joint, said support strut being rotatable over the center of said pivoting joint when placed in said engaged position with said interlock means; said force along said support strut forcing said support strut in a rotational direction over the center of said pivoting joint for locking said support strut in said engaged position.
Claim 10
Dependent Claim
92 words
The stabilizer leg interlock means of claim 1, wherein: (p) said locking means includes a hook pivotally mounted for insertion into a hook receiving means located on respective insertable devices, said hook producing a force opposing the withdrawal of said device when engaged with said hook receiving means; (q) said interlock means including an interlock arm which is connected to said support strut when in its lock position and when so engaged forcing said locking means to pivot out of engagement with said hook receiving means and releasing said device for withdrawal.
Claim 11
Dependent Claim
99 words
The stabilizer leg interlock means of claim 9, wherein: (r) said interlock means includes a pivotally mounted strut receiving means, connected to said interlock arm, said strut receiving means being forced into a first position when out of engagement with said strut, responsive to said return means forcing said hook into engagement with said hook receiving means and rotates upon engagement when said strut is engaged and placed in its locked position to drive said interlock arm to rotate said hook out of engagement with said hook receiving means to release said insertable device for withdrawal from said cabinet.
