Assignee:

Federal-Hoffman, Inc. - Anoka MN

International Classification:

E05C 302

US Classification:

292240

Abstract:

A quarter turn latch (10) includes a latching member (12) connecting to an actuating member (14). The latching member (12) and actuating member (14) snap together from opposite sides of a mounting surface member (100). The latching member (12) includes a cam member (20) for engaging the complimentary latch member (102) to retain it against the mounting surface member (100). The mounting surface has a depressed portion (16) with an orifice (18) formed therein. The orifice has opposed straight sides (70) and rounded end portions (72). The actuating member includes a barrel shaped body (24) having opposed rounded larger radius corner portions (32) and opposed squared corner portions (34). The actuating member provides for rotation along the rounded portions (32) against the end portion (72) and straight side (70) while the squared portions (34) engage the straight side portion (70) to limit rotation to one quarter turn.

International Classification:

E05C 912

US Classification:

292 39

Abstract:

A latch system which includes a latch bar slidable up and down on an interior of an enclosure door. The latch system has a rack member mounted on the latch bar extending through an orifice in the door to engage an actuator on the exterior of the door. The latch bar has glides and retainer clips mounted to the latch bar for positioning the bar relative to the door. The door may include a gasket for sealing an enclosure, with the latch bar mounting outside of the sealed area. Retainer fingers include a roller which engage a latch catch mounted to the enclosure frame. The finger members and the rack members are reversible for mounting in either direction so that the door may be reversed at any time. The latch catches are configured for receiving a finger member at either end for engagement of the door.
