A combination sash lock and tilt latch secures a sash window that is slidable and tiltable with respect to a master window frame. The fastener includes a lock assembly and latch assembly. The lock assembly is releasably mounted upon the sash window meeting rail without screws, using legs received within corresponding openings in the rail. The lock assembly is releasably secured thereto by a spring causing engagement between the legs and rail openings. The lock assembly includes a pivotable cam to releasably engage a keeper on the master frame, and a pivotable arm extending into the meeting rail. The latch assembly includes biasing means and a latch member with a plurality of openings, each configured to receive the post of the lock assembly, within the meeting rail, with the lock assembly installed thereon in any one of a plurality of positions corresponding to said openings in said latch member.

A status indicator for a locking mechanism may include a status indicator face, a status indicator plate, a cam coupling, and a locking mechanism coupler. The status indicator face and status indicator plate may be at least partially moveable relative to one another. The locking mechanism coupler may have a greater rotational range of motion than the cam coupling. The status indicator face may indicate the state of a locking mechanism and may have a viewing angle greater than or equal to 180 degrees.

A door latch assembly includes a housing, an inside and outside handle operably coupled with the housing, and a latch plunger. A latch cam is operably coupled with the inside and outside handles, and the latch cam further includes a crank arm slidably disposed against an inclined surface of a plunger leg operably coupled to the latch plunger. A biasing member urges the latch plunger to an extended position, wherein rotation of the inside or outside door latch handle in a first direction rotates the crank arm of the latch cam and displaces the plunger leg of the latch plunger and the latch plunger to a retracted position against the urging of the biasing member.

A door latch assembly includes a housing, an inside and outside handle operably coupled with the housing, and a latch plunger. A latch cam is operably coupled with the inside and outside handles, and the latch cam further includes a crank arm slidably disposed against an inclined surface of an offset plunger leg operably coupled to the latch plunger. A biasing member urges the latch plunger to an extended position, wherein rotation of the inside or outside door latch handle in a first direction rotates the crank arm of the latch cam and displaces the plunger leg of the latch plunger and the latch plunger to a retracted position against the urging of the biasing member.

A latch that can be unlatched with a force exerted on a front handle of a drawer or other enclosure. The latch includes an end cap that interacts with a cam surface of a body and, upon doing so, disengages the catch from an opening on a strike plate or cabinet body. When the catch is disengaged, the latch can allow for the opening of the enclosure. The latch therefore allows for a simple forward motion to open and close the latch, and further allows the latch to be used with many different enclosures.

A combination sash lock and tilt latch in one integral fastener may suitably secure a sash window that is slidable and tiltable with respect to a master window frame. The fastener includes a lock assembly and latch assembly. The lock assembly is releasably mounted upon the meeting rail of the sash window without screws, using legs received within corresponding openings in the rail. The lock assembly is secured thereto by a biasing member causing engagement between the legs and rail openings. The lock assembly includes a pivotable cam to releasably engage a keeper on the master frame, and a pivotable arm extending into the meeting rail. The latch assembly includes biasing means and a latch member, which includes a fixed funnel member and a flexible funnel member on a distal end of a flexible beam, to blindly engage the lock assembly arm within the meeting rail, when installed therein.

An ink cartridge for an inkjet printer includes a bottom face and a front face; an ink interface on the front face of the ink cartridge for connection to a cartridge receiving structure; a guide interface in the bottom face for guiding the cartridge along a straight line during insertion into the cartridge receiving structure for connecting the ink interface; a latch track disposed in the bottom face of the ink cartridge to guide a latch of the cartridge receiving structure; a latch stop disposed in the latch track for engaging the latch, where the latch track comprises a locking track and an unlocking track to accommodate movement of the latch with respect to the latch stop, the locking track being at least partly separate from the unlocking track; and a latch guide for redirecting the latch towards the locking track, rather than the unlocking track.

The parts forming the force transmission connection from the spindle shaft of the handle of the lock body to the bolt include a spring, which is also arranged to transfer force. The spring is used to eliminate the protrusion of the bolt caused by tolerance variations, when the handle installed into the lock body is turned to its extreme position to open the door.

A latch assembly is provided where a latch bolt is moveable to open and close a door by unblocking pivotal movement of the latch bolt. Turning a door knob or door handle does not directly result in a corresponding retraction of the latch within a sleeve, but rather unblocks the bolt to freely pivot away from a latched position. In some embodiments, the latch assembly may include a sleeve that allows for a backset to be infinitely adjusted relative to an aperture of the sleeve. In some embodiments, the latch assembly may further include a dead latch to provide additional security against forced entry.

Certain aspects of the technology disclosed herein include an apparatus and method for storing energy in a electromechanical lock. The electromechanical lock can include a main housing and a deadbolt. The main housing can be configured to extend a deadbolt along a path to lock and/or unlock a door. The deadbolt can have a hollow inner region configured to receive an energy storage device. The energy storage device within the deadbolt can be electrically connected to the main housing. The energy storage device can be used to power an actuator and/or accelerometer in the main housing.
