Lock device for opening/closing body
09850691 · 2017-12-26 · ·

A lock device is provided with a housing, a rotary member, a pair of link rods provided with a hook part, a spring for the rotary biasing of the rotary member, and an operative member mounted so as to be able to be inserted into the housing. A cam protrusions formed in the rotary member, and a wall part having a cam slope which abuts the cam protrusion is formed in the operative member. The configuration is such that by inserting the operative member, the rotary member resists the biasing force of the spring and rotates, and the hook part of the link rods slides in a position in which it does not engage with the lock part.

THREE POINT LOCK

A fenestration assembly includes a frame assembly, a movable sash assembly and a lock assembly. The lock assembly includes a first lock and a second side lock. The first lock operatively locks and unlocks the moveable sash to the frame assembly in a first direction only when the movable sash is in a fully closed position. The first side lock operatively locks and unlocks the movable sash in a second direction perpendicular to the first direction both when the movable sash is in the fully closed position and a partially open position.

Door silencing mechanism system and associated methods
11674342 · 2023-06-13 ·

A door silencing mechanism and methods to eliminate latch noise associated with a door latch having a spring latch bolt and a bolt housing are described. This mechanism and methods can include an actuator having a first end and a second end and moveable between a first position and a second position. This mechanism can also include a device coupled to the first end of the actuator to maintain the spring latch bolt within a bolt housing using the second end of the actuator when the device holds the actuator in the first position and to release the spring latch bolt from within the bolt housing by moving the second end of the actuator in response to the actuator moving to the second position in response to contact with a doorjamb.

ELECTROMECHANICAL DRIVE SYSTEM
20230175289 · 2023-06-08 ·

An illustrative access control system includes a locking assembly operable in locked and unlocked states, and a drive assembly operable to actuate the locking assembly. The drive assembly includes an electromechanical actuator, and energy storage device, and a control system. The electromechanical actuator is operable, upon receiving power, to transition the locking assembly between the locked state and the unlocked state. The energy storage device is electrically coupled to the electromechanical actuator, and configured to store electrical power from the power supply when the drive assembly is coupled to the power supply. The control system is configured to couple the drive assembly to the power supply in response to a first condition, and to thereafter transmit energy only from the energy storage device to power the electromechanical actuator, based at least in part upon a level of energy stored in the energy storage device.

Stirling cycle machine

A rod seal assembly. The rod seal assembly includes a housing between two spaces configured to receive a reciprocating rod, the reciprocating rod disposed within a first space and a second space, a floating bushing configured to move axially and radially within the housing and disposed coaxially around the reciprocating rod, a rod seal configured to seal the outside diameter of the reciprocating rod relative to an inside surface of the floating bushing, and at least one stationary bushing fixed within the housing that may form a seal with the floating bushing to the axial flow of fluid in the presence of a pressure difference between the two spaces.

Magnetic lock

The invention discloses a magnetic lock, comprising a lock body mechanism and a stopper, wherein the lock body mechanism comprising a housing, a swinging fastener, an inner cover, a latch for engaging with the stopper, and a magnetic unlocking member for controlling disengagement of the latch from the stopper; the swinging fastener is hinged to the inner cover, the inner cover is snapped with the housing, the latch is slidably arranged inside the housing, the swinging fastener comprises a push rod abutting against the latch, and the magnetic unlocking member is used to form a repulsive force applied to the swinging fastener to drive the latch away from the stopper. Unlocking the latch may only be achieved by means of magnetic unlocking member which is independent from the lock body mechanism so as to prevent children from opening this magnetic lock arbitrarily and which is also convenient to use.
