Abstract
A mechanism which selectably limits the opening of a hinged window vent. The mechanism has a releasable arm that permits the vent to be conveniently opened beyond the selected limit. An assembly is disclosed for limiting travel of a vent relative to a frame. The assembly includes a security fastener for restricting transition of the assembly between a locked configuration and an unlocked configuration. An arm is pivotally connected to a mounting bracket by a locking plate and a loading pin.
Claims17
A mounting assembly for releasably coupling an arm to a fixture, comprising:
- (a) a mounting bracket
- (b) means for pivotally coupling the arm to the mounting bracket;
- and
- (c) means for releasably retaining the arm and the mounting bracket in the pivotal coupling.
An interconnect assembly for limiting the movement of an arm extending between a window and a frame, comprising:
- (a) a mounting bracket;
- (b) a locking plate pivotally coupled to the arm;
- (c) a fastener for releasably engaging the locking plate and the mounting bracket;
- and
- (d) a loading pin configured to releasably locate the arm and the mounting bracket in a pivoting relation.
A detachable arm limiting assembly for a frame and a hingedly attached vent, the assembly comprising:
- (a) a mounting bracket attachable to the frame, the bracket having a first keyway and a threaded hole spaced from the first keyway;
- (b) a fastener engaging the threaded hole between a captive position and a release position;
- (c) a locking plate having a second keyway sized to removably engage the fastener and a loading pin spaced from the second keyway, the loading pin sized to releasably engage the first keyway;
- (d) an arm pivotally attached to the loading pin;
- (e) a shoe pivotally attached to the arm;
- and
- (f) a track sized to slidably receive the shoe.
- the locking plate movable relative to the mounting bracket between a release position and an interlock position.
A method for limiting the opening of a window vent hingedly attached to a window frame, comprising:
- (a) providing a mounting bracket, a fastener engaging the mounting bracket, a locking plate, and a loading pin, the locking plate being pivotally attached an arm;
- (b) attaching the bracket to the window frame;
- (c) coupling the locking plate and the bracket;
- (d) translating the locking plate to an interlock position;
- and
- (e) securing the locking plate to the bracket with the fastener.
