Night latch

A latch, placed in a recess in a window or door to limit door or window movement, said latch comprising:

• (a) a housing, said housing having a front face, a cavity, one or more openings into said cavity, and at least one opening in said front face to said housing cavity;
• (b) a tumbler, said tumbler having a front end and a rear end, said rear end of said tumbler being pivotally mounted to said housing, said tumbler being sized and shaped so it may occupy a retracted position within said housing cavity and an activated position wherein at least a portion of said tumbler front end extends from said opening of said housing;
• (c) a spring means, said spring means biasing said tumbler to said activated position;
• (d) an actuation means, said actuation means being pivotally mounted to said housing and capable of pivoting from an engaged position to a disengaged position;
• said actuation means comprising a button portion and a body portion, said body portion comprising a spring member extending from an end of said body portion opposed to said button portion and extending from said end toward said button portion, said button portion, body portion and said spring member being a continuous member, said spring member biasing said actuation means toward said engaged position, said button portion having a surface exposed through a housing opening such that said button may be toggled to counter said biasing of said spring member and pivot said actuation means from said engaged position to said disengaged position;
• said actuation means capable of co-acting with said tumbler to retain said tumbler in said retracted position until said actuation means is toggled to said disengaged position where said tumbler is then biased by said spring means into said activated position;
• said tumbler in said activated position being capable of resisting rotation back into said retracted position.

A latch, placed in a recess in a window or door to limit door or window movement, where said latch comprises:

• a housing, said housing having a top surface, at least two side surfaces extending from said top surface, and a bottom surface extending from at least a portion of one side surface to at least a portion of the other side surface;
• said housing having a tumbler pivotally mounted in said housing, said tumbler capable of occupying a recessed position where said tumbler is within the housing, and an activated position wherein at least a portion of said tumbler extends from an opening in the top surface of said housing, said tumbler being biased by a spring means to said activated position;
• said tumbler having an upper surface, a lower surface, a front end and a rear end, said front end being generally straight with at least a portion of said front end forming at an acute angle with said top surface, said front end also comprising one or more protrusions on at least a portion of said generally straight front end;
• said tumbler being retained in said recessed position in said housing by an actuating means;
• said actuating means comprising a button pivotally mounted in said housing and moveable between a first and a second button positions, said button comprising a top member with a top and bottom surface, a body member extending from said bottom surface of said top member, and a spring member extending from said body member at a location opposed to said bottom surface and extending from said location toward said bottom surface, said top, body and spring member being a continuous member, said top member of said button moving said body member of said button from a first position, where said body member retains said tumbler in its recessed position to a second position where said tumbler is released and said tumbler is permitted to pivot to an activated position, and wherein said spring member forces said body member of said button to said first position when said tumbler has been released, said tumbler in said activated position being capable of resisting rotation back into said retracted position when a force is applied to said tumbler front end.

A latch, placed in a recess of a window or door to limit door or window movement, where said latch comprises:

• a housing, said housing having a top surface, at least two side surfaces extending from said top surface, and a bottom surface extending from at least a portion of one side surface to at least a portion of the other side surface, said housing having a tumbler pivotally mounted in said housing said tumbler capable of occupying a recessed position where said tumbler is within the housing and an activated position wherein at least a portion of said tumbler extends from an opening in the top surface of said housing, said tumbler being biased by a spring means to said activated position;
• said tumbler having an upper surface, a lower surface, a front end and a rear end, said tumbler being retained in a recessed position in said housing by an actuating means, said actuating means comprising a button pivotally mounted in said housing and moveable between a first and a second button positions, said button comprising a top surface and a bottom surface said bottom surface having a body member extending therefrom, said body member having a first end and a second end;
• said first end extending from said bottom surface, said second end having a flexible member extending therefrom and toward said button surface, said button, said body member and said flexible member are a single member, said top surface of said button moving said body member from a first position, where said body member retains said tumbler in its recessed position to a second position where said tumbler is released and said tumbler is permitted to pivot to an activated position, and where said flexible member of said button forces said body member to said first position when said tumbler has been released, said tumbler in said activated position being capable of resisting rotating back into said retracted position.
