Double-action, adjustable, after-market sash stop

A stop, for use in limiting movement of a sash window or door with respect to a master frame, said stop comprising:

• a housing;
• a tumbler, said tumbler comprising a first end and a second end;
• said tumbler being pivotally mounted to said housing;
• said second end of said tumbler comprising a bearing surface;
• a first biasing member, said first biasing member biasing said second end of said tumbler to pivot outward from said housing;
• said tumbler being configured for pivotal movement between at least a first tumbler position and a second tumbler position;
• a portion of said biasing member selectively contacting a portion of a contoured feature on said housing to limit said outward pivotal travel of said tumbler at said second tumbler position;
• a mounting flange, said mounting flange extending from said housing;
• said mounting flange being offset from a bottom of said housing;
• a safety member, said safety member being configured to slide relative to said tumbler toward an engaged position in which said safety member engages said housing so as to block pivotal movement of said tumbler while said tumbler is in said first tumbler position, said pivotal movement of said tumbler being blocked until said safety member is disengaged, wherein said disengagement of said safety member comprises sliding said safety member toward said tumbler so as to be clear of said housing;
• a second biasing member configured to bias said safety member toward said engaged position;
• wherein when said tumbler is in said first tumbler position, said bearing surface of said tumbler limits movement of the sash window or door between a closed position and a partially open position, said partially open position being between the closed position and a full open position;
• said tumbler permits movement of the sash window or door beyond the partially open position when in said second tumbler position;
• wherein said tumbler pivots between said first tumbler position and said second tumbler position by a force being selectively applied at said first end of said tumbler;
• wherein the force being selectively applied at said first end of said tumbler causes said tumbler to toggle from said first tumbler position to a retracted position, said retracted position being a position wherein at least a portion of said second end of said tumbler is retained within said housing;
• and wherein upon removal of the force from said first end of said tumbler, said tumbler is biased from said retracted position to said second tumbler position;
• and
• wherein said second tumbler position is a position wherein at least a curved surface of said second end of said tumbler protrudes out from said housing.

A stop, for use in limiting movement of a sash window or door with respect to a master frame, said stop comprising:

• a housing;
• a tumbler, said tumbler comprising a first end and a second end;
• said tumbler being pivotally mounted to said housing;
• said second end of said tumbler comprising a beating surface;
• a first biasing member, said first biasing member biasing said second end of said tumbler to pivot outward from said housing;
• said tumbler being configured for pivotal movement between at least a first tumbler position and a second tumbler position;
• a portion of said first biasing member selectively contacting a portion of a contoured feature on said housing to limit said outward pivotal travel of said tumbler at said second tumbler position;
• a mounting flange, said mounting flange extending from said housing;
• said mounting flange being offset from a bottom of said housing;
• a safety member, said safety member being configured to slide relative to said tumbler toward an engaged position in which said safety member engages said housing so as to block pivotal movement of said tumbler while said tumbler is in said first tumbler position, said pivotal movement of said tumbler being blocked until said safety member is disengaged, wherein said disengagement of said safety member comprises sliding said safety member toward said tumbler so as to be clear of said housing;
• a second biasing member configured to bias said safety member toward said engaged position;
• wherein when said tumbler is in said first tumbler position, said bearing surface of said tumbler limits movement of the sash window or door between a closed position and a partially open position, said partially open position being between the closed position and a full open position;
• said tumbler permits movement of the sash window or door beyond the partially open position when in said second tumbler position;
• and
• wherein said first biasing member comprises a helical torsion spring, said helical torsion spring comprising a helical coil with first and second arms extending therefrom.
