Claims
- 1. Latch for locking sliding closures, comprising: a housing adapted to be mounted on the stile of a sliding closure opposite an opposing jamb-mounted laterally enterable latch keeper, said housing having a front wall defing a slot; a latch having an inner portion within said housing and an outer portion registerable with said latch keeper beyond said housing, said latch being pivoted at said slot for selectively entering said latch keeper; and pivot means for deflecting said latch to enter said keeper, said pivot means being rotatably fixed to said housing about an axis of rotation and having laterally offset, oppositely facing, oppositely sloped first and second shoulders on opposite sides of said axis in a manner to have said shoulders cooperatively simultaneously engage said latch portion within said housing in deflecting relation when rotated in a first direction and to not deflectingly engage said latch portion when oppositely rotated, whereby said latch is supported by two shoulders when latched and yet is pivotable away from latching without interference from said shoulders.
- 2. Latch according to claim 1, in which said housing is generally rectangular, and has a side wall extending the length of said front wall, said pivot means being journaled in said side wall.
- 3. Latch according to claim 1, in which said latch is a flat, generally rectangular plate of a predetermined longitudinal extent, said plate front corners being notched to define said latch outer portion relative to said latch inner portion.
- 4. Latch according to claim 1, in which said latch outer portion has a terminal flange for latching to said keeper.
- 5. Latch according to claim 1, in which said latch inner portion defines front edge upsets opposite said housing front wall against passage of said inner latch portion through said slot.
- 6. Latch according to claim 1, including also spring means urging said latch into unlatched condition by resiliently engaging said latch inner portion with said housing front wall in bodily shiftable relation, said spring means cooperating with said housing to define the hinged relation of said latch to said housing.
- 7. Latch according to claim 1, in which said housing is generally rectangular, said latch is a flat, generally rectangular plate of predetermined transverse extent less than the transverse width of said housing, at least one of said pivot means shoulders being sized and shaped and mounted to fit between said latch inner portion and the rear wall of said housing in the plane of said latch portion.
- 8. Latch according to claim 7, in which said latch inner portion is upset opposite said shoulder in the plane of said latch portion to define a camming cooperating surface on said latch portion for said shoulder.
- 9. Latch according to claim 1, in which said housing defines a lateral extension, and including also a pull mounted on said extension, and a latch actuator adjacent said pull, said actuator comprising a lever for rotating said pivot means to deflect said latch deflection.
- 10. Latch for locking sliding closures, comprising a housing adapted to be mounted on the stile of a sliding closure opposite an opposing jamb-mounted laterally enterable latch keeper, said housing having a front wall defining a slot; a bodily shiftable latch having an inner portion disposed in said housing and an outer portion registerable with said latch keeper beyond said housing, said latch being pivotable at said slot about a first axis of rotation parallel with said slot for outer latch portion lateral movement to enter said latch keeper; and housing-supported pivot means for pivotally deflecting said latch to enter said keeper, said pivot means having an second axis of rotation and first and second oppositely facing shoulders on opposite sides of said second axis of rotation in laterally offset relation, whereby upon rotation in a first direction each shoulder simultaneously engages said latch for deflection into said keeper in a first rotated position of said pivot means, said shoulders being shaped to accommodate the undeflected condition of said latch in a second rotated position of said pivot means.
- 11. Latch according to claim 10, in which said housing is generally rectangular, and has a side wall extending along said front wall, said pivot means being journaled in said side wall.
- 12. Latch according to claim 11, in which said latch is a flat, generally rectangular plate of a predetermined longitudinal extent, said plate front corners being notched to define said latch outer portion relative to said latch inner portion.
- 13. Latch according to claim 12, in which said latch outer portion has a terminal flange for latching to said keeper.
- 14. Latch according to claim 10, including also spring means mounting said latch to said housing wall.
- 15. Latch according to claim 14, in which said housing is generally rectangular, said latch is a flat, generally rectangular plate of predetermined transverse extent less than the transverse width of said housing, at least one of said pivot means shoulders being sized and shaped to fit between said latch inner portion and the rear wall of said housing in the plane of said latch portion in the undeflected condition of said latch.
- 16. Latch according to claim 15, in which said latch inner portion defines a camming cooperating surface opposite said shoulder.
- 17. Latch according to claim 16, in which said housing defines a lateral extension, and including also a pull mounted on said extension, and a latch actuator adjacent said pull, said actuator comprising a lever for rotating said pivot means to determine latch deflection, whereby with said latch plate in the undeflected condition with its outer portion terminal flange opposite said latch keeper, one said pivot means shoulder cams across said latch plate to deflect said latch plate to said deflected condition, and the other said latch plate in the deflected condition with the latch outer portion flange deflected into and engaged with said keeper.
- 18. Latch for sliding closures comprising a rocker having a hooked terminus, and means to deflect said rocker into engagement with a latch keeper, said means comprising a housing having a slot about which said rocker rocks, and rocker rocking means comprising a biasing spring and an oppositely acting pivot having first and second shoulders in offset relation for both simultaneously rocking said rocker into keeper engagement upon pivot rotation, said shoulders being shaped to permit return movement of said rocker out of keeper engagement responsive to reverse pivot rotation.
