Claims
- 1. A latch for locking a moveable member to a stationary member, the latch comprising:
a housing; a bolt positioned at least partially within the housing; and a catch, slideably engaging the bolt, the catch configured to retain the bolt in an unlocked position and release the bolt in response to an external force acting against the catch, such that the bolt operably engages a moveable member or a stationary member.
- 2. The latch according to claim 1, wherein the latch is fastened to a moveable member, or a stationary member, each of the members selected from a group consisting of a window, a drawer, a desk, a table, and a door.
- 3. The latch according to claim 1, wherein the catch further comprises a trigger pin configured such that the external force acts directly against the trigger pin to move the catch.
- 4. The latch according to claim 3, further comprising a baseplate connected to the housing and configured such that the trigger pin extends through the baseplate.
- 5. The latch according to claim 1, further comprising a handle, integrally connected to the bolt, the handle configured to retract the bolt into the housing in response to a force that removes the handle from the housing.
- 6. The latch according to claim 1, further comprising at least one bolt spring positioned within the housing and configured to move the bolt into a locked position.
- 7. The latch according to claim 1, further comprising at least one catch spring positioned between the housing and the catch, the catch spring configured to position the catch between the bolt and a slide plate of the housing in response to the bolt moving toward the unlocked position.
- 8. The latch according to claim 1, wherein the latch further comprises:
a first chamfered edge on the catch; and a second chamfered edge on the bolt, the second chamfered edge slideably engaging the first chamfered edge as the bolt moves past the catch.
- 9. The latch according to claim 8, wherein the first and second chamfered edges are angled at approximately 45 degrees each.
- 10. The latch according to claim 8, wherein the first and second chamfered edges independently angle within a range of between about 10 degrees and about 75 degrees each.
- 11. A window latch for locking a window, the window latch comprising:
a housing; a bolt, positioned at least partially within the housing, the bolt configured to secure a movable window in a locked position; and a catch slideably engaging the bolt, the catch configured to retain the bolt in an unlocked position and release the bolt in response to movement of a trigger pin.
- 12. The window latch according to claim 11, wherein the trigger pin is integrated with the catch.
- 13. The window latch according to claim 11, wherein the trigger pin is integrated with a window frame configured to receive the bolt in the locked position.
- 14. The window latch according to claim 11, wherein the housing further comprises a guide connected to the housing, the guide configured to ensure substantially perpendicular movement of the catch with respect to a back wall of the housing.
- 15. The window latch according to claim 11, wherein the bolt comprises a recessed area, the recessed area configured to permit free passage of the trigger pin.
- 16. The window latch according to claim 11, further comprising at least one catch spring positioned between a back wall of the housing and the catch, the catch spring configured to position the catch between the bolt and a slide plate transverse to a back wall of the housing when the bolt is in an unlocked position.
- 17. A window latch for locking a window, the window latch comprising:
a housing configured to connect to a window frame with at least one fastener; a handle, movably connected to the housing, the handle configured to cover the fastener when the handle is in a locked position and allow access to the fastener when the handle is in an unlocked position; a bolt integrated with the handle, the bolt positioned at least partially within the housing; and a catch, slideably engaging the bolt, the catch configured to retain the bolt in an unlocked position and release the bolt in response to an external force against the catch.
- 18. The window latch according to claim 17, wherein the latch further comprises a trigger pin connected to the catch, and wherein the external force acts directly against the trigger pin to move the catch.
- 19. The window latch according to claim 17, wherein the bolt comprises a pair of bolt extensions configured to lock the window in a closed position.
- 20. The window latch according to claim 17, further comprising:
a catch spring positioned between a back wall of the housing and the catch; a first chamfered edge on the catch; a second chamfered edge on the bolt; at least one bolt spring, within a spring cavity within the housing, the bolt spring configured to push a pair of bolt extensions from the housing to lock the window in a locked position; and wherein a bias force of the catch spring drives the catch between the bolt and a slide plate transverse to a back wall of the housing in response to the handle being drawn from the housing to hold the bolt in an unlocked position.
