Abstract

A vent stop is installed into a window/door to limit travel therein of a sash member, and being particularly adapted to permit ease of its installation, especially into a wooden door/window. The stop incorporates multiple retention features to inhibit the stop's removal, once properly installed. The retention features include a wedge-shaped protrusion located at a distal end of the stop housing, which engages the wood of the window opening when pivotally installed therein, to secure a first end of the stop. The opposite end of the stop may be redundantly secured. A first feature for securing the opposite end may comprise one or more arcuate flanges on housing side walls, flanges being adapted to unidirectional movement so as to permit its movement relative to the window opening during installation, but thereafter deterring counter-pivotal motion that would allow removal of the vent stop. A second feature comprises a deformable spring clip.

Claims22

Dependent claims

A vent stop comprising:

a housing, said housing having a first end and a second end, said housing comprising:
(a) a top plate, said top plate comprising an opening;
(b) one or more housing walls, said one or more walls extending from said top plate to a distal bottom to form a cavity;
said one or more housing walls comprising a first end wall portion and a second end wall portion at said first and second ends of said housing, respectively, and a first elongated side wall portion and a second elongated side wall portion with each extending between said first and second end wall portions;
said one or more housing walls extending generally orthogonally from said top plate;
a portion of said second end wall portion comprising curvature to form an arc-segment having an origin being proximate to said top plate at said housing first end;
(c) at least one arcuate flange protruding from said first elongated side wall portion of said one or more housing walls, said at least one arcuate flange being oriented to have an edge with at least a portion therein having a radius of curvature with an origin being proximate to said housing first end;
said at least one arcuate flange comprising a side surface, said side surface comprising two or more teeth to permit unidirectional motion upon contact with a faying surface;
(d) at least one arcuate flange protruding from said second elongated side wall portion of said one or more housing walls, said at least one arcuate flange of said second side wall portion being oriented to have an edge with at least a portion therein having a radius of curvature with an origin being proximate to said housing first end;
said at least one arcuate flange of said second side portion comprising a side surface, said side surface comprising two or more teeth to permit unidirectional motion upon contact with a faying surface;
(e) a wedge-shaped protrusion protruding from said first end wall portion;
(f) a spring clip, said spring clip protruding from said second end wall portion;
and
(g) a block-shaped protrusion protruding from said first end wall portion between said top plate and said wedge-shaped protrusion;
a tumbler, said tumbler having a first end and a second end, said tumbler being pivotally mounted to said housing to be pivotable between a retracted position, wherein said tumbler is disposed within said housing cavity, and an extended position, wherein at least a portion of said tumbler second end is protruding out said opening of said top plate;
a means for positioning said tumbler to occupy said retracted position or said extended position;
and
wherein said protrusion and said at least one unidirectional arcuate flange serve to retain said vent stop within an opening in a window when installed therein.
