Abstract: A latch assembly includes a housing for inserting through an opening or breach in a door panel and secured to the panel by a retaining cage. In the preferred embodiment, the housing and the breach will have the same cross-sectional square shape. A retaining cage includes a retainer plate and a plurality of supporting legs and substantially surrounds the housing when the assembly is mounted on a door panel. At each cornering edge of the housing, a depression is formed for receiving a retainer extension formed at the end of each supporting leg. Each supporting leg also includes a support claw or tip which, in the mounted position, engages a surface of the door panel and pierces any non-conductive coating thereon so that the rotary bar handle and the other parts of the assembly may be electrically grounded. The cooperative configuration of the housing and the retaining cage permits mounting of the assembly in one of four positions.

Abstract: This invention is an improved switch cabinet latch of the type having a cabinet body and a cabinet door hinged to it with the door held in closed position by means of a push-rod lock on the cabinet door with push rods movable axially by rotational movement of an actuating element such that in the closed position closing ends on the push rods which face away from the push-rod lock reach behind closing faces mounted on the cabinet body while in the open position they move away from the closing faces. By virtue of the special configuration of the ends of the push rods and lock blocks mounted on the cabinet body, an improved clamping of the door to the cabinet body is achieved in combination with a hasp of the push-rod lock in the closed position. This clamping is initiated in forced sequence by two steps in the rotational movement of the actuating element of the push-rod lock.

Abstract: A lock assembly for cabinet doors comprising a mounting plate attachable to the door panel and provided with a depression in its front face to receive a handle. The handle is connected to an operating shaft for a lock adjusting member in a spring loaded manner to cause the handle to be ejected from the depression pivoting about an axis perpendicular to the axis of rotation of the adjusting member. The hand lever is retained in and released from the depression by means of the lock assembly. The lock is installed in the mounting plate separate from the depression with the handle therein, and penetrates the door panel through an opening. The lock controls a slide adjustably disposed in the mounting plate by means of a detent element engaged in the depression, the detent element retaining the handle in the depression when the lock is in the locking position and releasing the handle which is ejected from the depression when the lock is in the unlocked position.
