Abstract
A sliding door latch with a finger pull mechanism is described that fits within a standardized aperture normally utilized for a hinged door latch. Provided is a latch assembly having an extendable latching hook for mounting in a sliding door and latching with a strike plate mounted in a door frame and a finger pull mechanism for accessing the sliding door from within a surrounding framework. Included are a housing assembly for fitting within the sliding door, an exposed edge plate mounted to the edge of the sliding door beside the housing assembly, a latching hook for engaging with the strike plate and extendable through the exposed edge plate, and a finger pull mechanism mounted in the edge plate.
Claims22
A sliding door latch assembly for engaging with a door frame placed strike plate, comprising:
- a) a housing assembly that fits within the sliding door;
- b) an edge plate having means for affixing to an edge of the sliding door and positioning said edge plate beside said housing assembly;
- c) means associated with said housing assembly for coupling with the strike plate, wherein when coupling with the strike plate a portion of said coupling means extends through said edge plate;
- and
- d) a finger pull means associated with said edge plate for accessing the sliding door from within a surrounding framework, wherein said finger pull means comprises:
- i) a finger pull member having first and second ends;
- ii) finger grasping means proximate said finger pull member first end;
- and
- iii) face plate attachment means proximate said finger pull member second end.
A sliding door latch assembly for engaging with a door frame placed strike plate, comprising:
- a) a housing assembly that fits within the sliding door;
- b) an edge plate having means for affixing to an edge of the sliding door and positioning said edge plate beside said housing assembly;
- c) means associated with said housing assembly for coupling with the strike plate, wherein when coupling with the strike plate a portion of said coupling means extends through said edge plate and comprises:
- i) a hooking lever with first and second ends, comprising:
- a hook formed at said first end;
- and
- a pivot means at said second end;
- and
- ii) means for moving said hooking lever from a retracted position to a strike plate engaging position;
- and
- d) a finger pull means associated with said edge plate for accessing the sliding door from within a surrounding framework, wherein said finger pull means comprises:
- i) a finger pull member having first and second ends;
- ii) finger grasping means proximate said finger pull member first end;
- and
- iii) face plate attachment means proximate said finger pull member second end.
A sliding door latch assembly for engaging with a door frame placed strike plate, comprising:
- a) an elongated housing assembly having first and second ends that fits within the sliding door;
- b) a rectangular edge plate having means for affixing to an edge of the sliding door and positioning said rectangular edge plate proximate said housing assembly second end;
- c) hooking means associated with said housing assembly for hooking to the strike plate, wherein when hooking with the strike plate a portion of said hooking means extends through said rectangular edge plate;
- and
- d) a finger pull means associated with said edge plate for accessing the sliding door from within a surrounding framework, wherein said finger pull means comprises:
- i) a finger pull member having first and second ends;
- ii) finger grasping means proximate said finger pull member first end;
- and
- iii) face plate attachment means proximate said finger pull member second end.
A sliding door latch assembly for engaging with a door frame placed strike plate, comprising:
- a) an elongated housing assembly having first and second ends that fits within the sliding door;
- b) a rectangular edge plate having a narrower top and bottom borders and wider side borders, comprising:
- i) means for affixing to an edge of the sliding door and positioning said rectangular edge plate proximate said housing assembly second end;
- ii) an upper finger pull mounting channel;
- and
- iii) a lower aperture for receiving a hook member;
- c) a hook assembly mounted in said housing assembly for releasably hooking to the strike plate, wherein when releasably hooked with the strike plate a portion of said hook assembly extends through said lower aperture;
- and
- d) a finger pull associated with said edge plate for accessing the sliding door from within a surrounding framework, wherein said finger pull comprises:
- i) a finger pull member having first and second ends;
- ii) finger grasping means at said finger pull member first end;
- and
- iii) face plate attachment means hinged to said edge plate top border.
In combination, a sliding door latch and strike plate, said combination comprising:
- a housing including a frame member;
- an edge plate disposed at an end of said housing and having an aperture formed therein;
- a latchbolt assembly disposed in said housing, said latchbolt assembly including a bracket supported by said frame member for movement between a retracted position and an extended position along a first axis, a catch pivotally connected to said bracket and having a hook formed on an end thereof and an actuator connected to said bracket for moving said bracket between said retracted and extended positions;
- a hook guide mechanism including a stop engaging said catch as said bracket is moved towards said extended position to rotate said catch from an unlatched position to a latched position about a second axis which is perpendicular to said first axis when said hook extends through said aperture of said edge plate;
- and
- a strike plate having a vertical hook engaging edge, said hook engaging said vertical hook engaging edge in said latchbolt extended position.
A sliding door latch assembly comprising:
- a housing including a frame member;
- an edge plate disposed at an end of said housing having an aperture formed therein, a pair of parallel faces including an outside face, and a finger pull opening;
- said edge plate having a finger pull pivotally connected thereto;
- a latchbolt assembly disposed in said housing, said latchbolt assembly including a bracket supported by said frame member for movement between a retracted position and an extended position along a first axis on a generally horizontal plane, a catch pivotally connected to said bracket and having a hook formed on an end thereof and an actuator connected to said bracket for moving said bracket between said retracted and extended positions;
- and
- a hook guide mechanism including a stop engaging said catch as said bracket is moved towards said extended position to rotate said catch from an unlatched position to a latched position about a second axis, said second axis being in said generally horizontal plane and about perpendicular to said first axis when said hook extends from said aperture of said edge plate in said latched position.
