Determining a position of a deadbolt used to lock and unlock a door is disclosed. An electromechanical lock can include a deadbolt that can retract or extend along a linear path as the door is to be locked and unlocked. A sensor such as an accelerometer can rotate along a non-linear path as the deadbolt moves along a linear path. The accelerometer can determine a gravity vector that can be indicative of a position of the accelerometer along the non-linear path. A controller can then determine a position of the deadbolt based on the gravity vector.

Certain aspects of the technology disclosed herein include an apparatus and method for electrically and mechanically connecting a deadbolt to a main housing of a lock. The main housing can be configured to extend a deadbolt along a path to lock and/or unlock a door while receiving electrical energy from an energy storage device disposed in the deadbolt. The energy storage device disposed in the deadbolt can be proximate to one or more electrical contacts electrically connected to one or more components in the main housing via conductive components of a bolt carriage. The bolt carriage includes a groove attachable to a male detent connector attached to the deadbolt. The groove in the bolt carriage provides a mechanical connection to the deadbolt and also aligns pogo pins with electrical components of the bolt carriage to enable electrical transmission from the deadbolt to the main housing.

Described are embodiments of a tapered bolt receiver for a door lock to accommodate misalignment, between a deadbolt mounted to a door, and an opposing jamb. The tapered bolt receiver can be configured to accommodate misalignment for a deadbolt having a non-tapered bolt, such as for an electromechanical smart lock having a battery stored within a battery compartment that is integrated with an enhanced bolt. Also described are embodiments of a deadbolt plate pivot assembly that is pivotably mountable to a corresponding deadbolt assembly to define a plate pivot system, to accommodate a beveled door edge. An illustrative embodiment of the deadbolt plate pivot assembly includes opposing plate that captures a hinge assembly, which can include plastic plate hinges, which serve to locate the deadbolt plate pivot assembly with respect to a corresponding bolt housing, and can provide a spring force and/or constant torque when mounted to a beveled door.

Adjustment device of the opening of a door of the type including two opposite members apt to be mounted to a door and to a post, respectively, and provided with housing holes of screws for the engagement with a surface, one of the bodies including a solid body except for a cavity provided on one of the side walls, the other one of the bodies including an outside shell internally provided with a housing cavity of a sliding body, characterised in that adjustment means of the movement of the sliding body are furthermore provided, arranged perpendicularly to the sliding body housed within a cavity provided on the top surface of the outer shell as well as dampening and thrust means of the sliding body.

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.

A sash window fastener includes lock and latch assemblies, and a fitting. The lock mounts upon the meeting rail, and includes a pivotable cam to engage a keeper on the master frame, and a pivotable arm acting as a follower. The arm interconnects with the latch within the meeting rail, so cam rotation controls arm positioningcausing translation of the latch. The cam can occupy three positions causing three corresponding latch positions: an extended position securing the cam to the keeper, with the latch engaging the master frame to prevent tilting, and also receiving a post of the fitting therein to further secure the window against impact loading; a first retracted position disengaging the cam from the keeper, and permitting sliding of the window into an open position that also elevates the latch member above the post; and a second retracted cam position causing latch member retraction that permits tilting.
