Abstract: A vent operator assembly employing a pair of operator arms which simultaneously control the position of an edge opening vent for recreational vehicles and the like. An operator body is secured to the inner side of the recreational vehicle adjacent to the vent opening therein. The body mounts a worm gear extending between a wall of the body and a cup recess in a bridge extending across a sector shaped recess in the body. A pair of operator arms, each including integral gears are journaled in the body from within the sector recess for simultaneous rotation in opposite arcs. The operator arms are relatively rigid except for the outer 16% which is a flexure spring element. Each spring element mounts a roller which engages a track in the edge of the vent cover opposite its hinged side. Upon rotation of a knob connected to the worm gear, the operator arms move simultaneously in the opposite direction to either open or close the vent cover.

Abstract: A window latch and handle assembly exhibiting an attractive appearance while providing a high degree of strength and small size. The assembly employs a pair of body members which are secured to a door or window frame and a unitary handle and latch. The handle extends from one side of the assembly of the two body parts and the latch from the opposite side thereof. A lock member with an elongated arm surface engages a key slot in the handle and latch. When in one orientation, the locking member allows the handle and latch to move laterally against the resistance of return spring and when turned 90.degree., effectively prevents movement of the handle and latch by direct broad area contact with one of the body parts. When rotated 90.degree., the lock member rests in the key slot allowing limited movement of the handle and latch to release the door or window.
