Window vent stop with flexible side engagement pieces

摘要

A window vent stop for use in a sliding member of a sliding sash window assembly or a sliding door assembly. The vent stop has a housing adapted to be disposed in a recess in the non-movable sash member of the assembly. This housing includes a cavity with a bottom plate. A tumbler has at least one pivot for pivotally securing the tumbler to the housing for movement between an extended position, to prevent movement of the sliding member and a retracted position, to allow movement of the sliding member. Also within the housing is a spring for biasing the tumbler toward the extended position. The housing has one or more flexible members extending from the end walls of the housing that secure the housing to the non-movable sash member.

1. A vent stop, for use with a sliding sash member, said vent stop comprising: a housing and a tumbler pivotally mounted to said housing for pivotal movement between a retracted position, where said tumbler is disposed within said housing, and an extended position, where a portion of said tumbler extends beyond said housing, a spring configured to bias said tumbler to pivotally travel toward said extended position, and means to limit said biased pivotal travel of said tumbler to said extended position; said housing having a top plate, a first sidewall, and a second sidewall, each of said first and second sidewalls extending from said top plate, said top plate forming a lip with respect to at least a portion of each of said first and second sidewalls, said housing having a front wall and a rear wall, each of said front and rear walls extending from said top plate and extending from said first sidewall to said second sidewall, and said housing comprising a flexible clip on said front wall, said flexible clip extending from said front wall of said housing at a position distal from said top plate, said flexible clip comprising an upper curved portion proximate a distal end of said flexible clip and spaced from said front wall, said upper curved portion positioned such that a line tangent to the upper curved portion is substantially parallel to a bottom surface of said top plate; and said housing comprising a first tooth member and a second tooth member, with each said tooth member extending from said first sidewall and said second sidewall, respectively, and each said first tooth member and said second tooth member extending generally toward said top plate and terminating with a top surface, said second tooth member being adjacent to said first tooth member with an inside surface of said first tooth member being displaced from an inside surface of said second tooth member; each of said first and second tooth members comprising a laterally disposed lip which forms a gap with said top plate.
