Abstract

Abstract A removable lock panel has two springs extending out of it which engage the drawer guides in a cabinet whereby the panel can be inserted in the cabinet, the springs will engage drawer guide notches therein, and a drawer can then be placed adjacent thereto and locked. So long as the drawer is locked there is no access to the springs or other means to remove the panel. This panel construction along with its associated cabinet and drawer parts permits adding a lockable drawer or tray to an existing cabinet with a minimum amount of cabinet alterations and actually without the necessity of using fasteners (nails, screws, adhesives).

Independent Claim 87 words
A lock panel that can be removably mounted in a cabinet and comprising a panel member with surfaces for extending substantially between the two opposite sides of the cabinet and from front to rear; edges on opposite sides of said panel member thick enough to fill the space between guides on the cabinet sides; detent means in each said panel edge for engaging the guides said detent means being inaccessible when a drawer is in place on the vertically adjacent guides on the cabinet sides and closed.
Claim 2
Dependent Claim 87 words
A lock panel that can be removably mounted in a cabinet and comprising a panel member with surfaces for extending substantially between the two opposite sides of the cabinet and from front to rear; edges on opposite sides of said panel member thick enough to fill the space between guides on the cabinet sides; detent means in each said panel edge for engaging the guides said detent means being inaccessible when a drawer is in place on the vertically adjacent guides on the cabinet sides and closed.
Claim 3
Dependent Claim 23 words
A lock panel according to claim 1 wherein said detent means includes a resilient member urging said means into engagement with said guide.
Claim 4
Dependent Claim 41 words
A lock panel according to claim 1 wherein each said detent means is a spring normally extending vertically from the edge of the panel into engagement with the vertically adjacent guide and compressible to within the confines of its associated edge.
Claim 5
Dependent Claim 33 words
A lock panel with a spring according to claim 3 wherein said spring extends obliquely from said panel edge for engaging like a barb a notch for that purpose in the cabinet guide.
Claim 6
Dependent Claim 29 words
