Abstract: A lockable window latch for double hung windows which pivots for cleaning includes an outer shell, a latching member which is slidable therein and a locking member which is rotatably received in the latching member and projects through an opening in the front wall of the shell. The locking element has an elongated control portion or handle which, when aligned transverse to the length of the latch permits latching and unlatching. When the handle is turned 90.degree. so as to be aligned with the length of the latch, one of its ends abuts against an internal wall surface of the shell thereby preventing unlatching.

Abstract: A tight-fitting corner construction is provided for use between adjacent, integrally connected parts of a common panel. A specially configured, three-sided miter groove is formed between the panel parts, and the panel is folded to close the groove and to form a corner between the panel parts. An overhanging lip is provided on one of the panel parts along one side of the groove. When the panel is folded to form a corner, the lip is brought into overlying engagement with inner surface portions of the other panel part to effect a thorough, tight-fitting closure of the groove. The panel preferably comprises a hollow, elongated plastic member which is used to form the sides and back of a drawer frame. Snap-acting locking devices are carried in hollow portions of the panel adjacent the corner locations to lock the panel in its folded configuration. A drawer front carries connectors which project into hollow portions of the drawer sides.
