A window vent stop for use in a sliding sash window assembly or a sliding door assembly. The vent stop has a housing adapted to be disposed in a recess in a non-movable sash member. 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 a sliding member and a retracted position to allow movement of the sliding member. Also within the housing is a spring for biasing the tumbler. The housing has one or more flexible members extending from the end walls of the housing that secure the housing to an opening in the non-movable sash member.

1. A vent stop, for use in an opening in a stile of a sash window, said vent stop comprising: a housing comprising: a top plate and one or more walls, said one or more walls joined to and extending from a bottom surface of said top plate to create a cavity; at least a portion of said top plate confi
1. A vent stop, for use in an opening in a stile of a sash window, said vent stop comprising: a housing comprising: a top plate and one or more walls, said one or more walls joined to and extending from a bottom surface of said top plate to create a cavity; at least a portion of said top plate configured to overhang beyond at least a portion of said one or more walls to create a lip, said top plate comprising an opening into said cavity; said housing comprising a first end and a second end;a tumbler pivotally mounted in said housing cavity and configured to pivot outwardly from a retracted tumbler position into an extended tumbler position where a portion of said tumbler protrudes out from said opening in said top plate;a spring configured to bias said tumbler relative to said housing;means for securing said first end of said housing to a first end of the opening in the window stile; anda retention member, said retention member mounted to said second end of said housing distal from said top plate and configured to cantilever away from said second end of said housing in a direction generally toward said lip of said top plate, said retention member configured to be at an angle with respect to said second end of said housing when in an extended position, said retention member configured to be flexible with respect to said housing, to resiliently flex from said extended position into a retracted position where a distal end of said retention member is proximal to said second end of said housing; said distal end of said retention member comprising an engagement surface, said engagement surface comprising a first portion and a second portion, said first portion comprising a substantially flat surface being at about a 55 degree angle to a bottom surface of said lip of said top plate when said retention member is in said extended position, and said second portion comprising an apex configured to be proximate to said bottom surface of said lip of said top plate but offset therefrom, said flat surface of said first portion positioned adjacent to said apex of said second portion with said first portion positioned further from said housing than said second portion, said retention member configured to flex into said retracted position when inserted in the opening in the window stile and to flex back toward said extended position when installed therein such that said first portion of said engagement surface is in an engagement position with respect to an interior edge of a second end of the opening in the window stile to secure said second end of said housing to the stile. 2. The vent stop according to claim 1, further comprising a stop configured to limit said outward pivoting of said tumbler in said extended tumbler position. 3. The vent stop according to claim 1, said housing further comprising a bottom wall distal from said top plate. 4. A vent stop, for use in an opening in a stile of a sash window, said vent stop comprising: a housing comprising: a top plate and one or more walls, said one or more walls joined to and extending from a bottom surface of said top plate to create a cavity; at least a portion of said top plate configured to overhang beyond at least a portion of said one or more walls to create a lip, said top plate comprising an opening into said cavity; said housing comprising a first end and a second end;a tumbler pivotally mounted in said housing cavity and configured to pivot between a retracted tumbler position and an extended tumbler position where a portion of said tumbler protrudes out from said opening in said top plate;a spring configured to bias said tumbler toward said extended tumbler position;a first retention member, said first retention member comprising a curved member configured to protrude from said first end of said housing, said first retention member configured to secure said first end of said housing to a first end of the opening in the window stile; anda second retention member mounted to said second end of said housing distal from said top plate and configured to cantilever away from said second end of said housing in a direction generally toward said lip of said top plate, said second retention member configured to be at an angle with respect to said second end of said housing when in an extended position, said second retention member configured to be flexible with respect to said housing to resiliently flex from said extended position into a retracted position where a distal end of said second retention member is proximal to said second end of said housing; said distal end of said second retention member comprising an engagement surface, said engagement surface comprising a first portion and a second portion, said first portion comprising a substantially flat surface being at about a 55 degree angle to a bottom surface of said lip of said top plate when said second retention member is in said extended position, and said second portion comprising an apex configured to be proximate to said bottom surface of said lip of said top plate but offset therefrom, said flat surface of said first portion positioned adjacent to said apex of said second portion with said flat surface of said first portion positioned further from said housing than said apex of said second portion, said second retention member configured to flex into said retracted position when inserted in the opening in the window stile and to flex back toward said extended position when installed therein such that said first portion of said engagement surface is in an engagement position with respect to an interior edge of a second end of the opening in the window stile to secure said second end of said housing to the stile. 5. A vent stop, for use in an opening in a stile of a sash window, said vent stop comprising: a housing having a first end and a second end and comprising: a top plate and one or more walls configured to create a cavity, said top plate comprising an opening into said cavity;a tumbler pivotally mounted in said housing cavity and configured to pivot between a retracted tumbler position and an extended tumbler position where a portion of said tumbler protrudes out from said top plate opening;a spring configured to bias said tumbler toward said extended tumbler position;a first retention member comprising a curved member configured to protrude from said first end of said housing to secure said first end of said housing to a first end of the opening in the window stile; anda second retention member mounted to said second end of said housing distal from said top plate and configured to cantilever away from said second end of said housing, said second retention member configured to cantilever in a direction generally toward said top plate, wherein a free end of said second retention member is distal from said second end of said housing when said second retention member is in an extended position; said second retention member configured to resiliently flex from said extended position into a retracted position, wherein said free end is proximal to said second end of said housing when said second retention member is in said retracted position; said free end of said second retention member comprising a substantially flat engagement surface being at about a 55 degree angle to a bottom surface of said top plate when said second retention member is in said extended position; said second retention member configured to flex toward said retracted position when inserted in the opening in the window stile and to flex back toward said extended position when installed therein such that said engagement surface is in an engagement position with respect to an interior edge of a second end of the opening in the window stile to secure said second end of said housing to the stile.
