摘要： A latch assembly includes a bolt selectively moveable between an extended position and a retracted position. A cam blocker is included and positionable in different configurations. In one configuration, the cam blocker allows the bolt to move towards the retracted position with actuation of a handle in two different rotational directions. In another configuration, the cam blocker allows the bolt to move towards the retracted position with actuation of the handle in only one rotational direction. The latch assembly is also adjustable between at least two different backset distances.

摘要： A push pad exit device comprising a horizontal push bar actuator mechanically linked to a vertical door handle assembly for use on the interior side of entrance doors where a means of emergency egress is desired, is presented. The operating mechanisms of the push bar actuator and vertical door handle assembly are concealed presenting a smooth uncluttered appearance. The push pad exit device further including an improved roller latch bolt. The improved roller latch bolt allows for a roller to make contact with a ramp surface of a corresponding strike plate on a sweep side of the plate and allows for the roller support to make contact with the strike plate on a latch side of the plate.

摘要： A locking mechanism includes a first member that is provided on one side to lock and is rotated about a rotating shaft, a second member that is provided on the other side to lock and comes into contact with the first member to rotate the first member, a rotation applying member that further applies a rotational force to the first member rotated by the second member, a restriction portion that restricts movement of the first member to be rotated in a direction in which the first member is released from a locked state, and an elastic portion that allows the first member and the restriction portion to be in elastic contact with each other and allows the first member and the restriction portion to start to be in elastic contact with each other before the first member rotated by the second member is further rotated by the rotation applying member in a release direction which is the direction in which the first member is released from the locked state.

摘要： A fastener operating structure includes a holding base and a fastening-connecting unit. The holding base is disposed at a first object. The fastening-connecting unit is movably disposed at the holding base. The fastening-connecting unit is fastened to a second object. Consequently, the holding base is disposed at the first object, and the fastening-connecting unit is coupled to or removed from the second object, so as to couple together and separate the first and second objects repeatedly and quickly.

摘要： A locking device for a lock including a box and a cover, such that the device can be isolated, which box includes therein a motor, a worm screw connected to the shaft of the motor, a locking shaft which is capable of sliding through a hole towards the outside of the box, and an elastic element with two ends, connecting the locking shaft with the worm screw, wherein one end of the elastic element is securely connected to the locking shaft and the other end is inserted between two threads of the worm screw such that, upon activating the motor, the worm screw rotates, moving the elastic element in order to drive the locking shaft, which transitions from being retracted to being extended and viceversa.

摘要： A door lock system comprising a first rotary configured to control extension and retraction of the deadbolt via a primary cam mechanism; a second rotary control configured to control extension and retraction of the latch; and a link configured to retract the deadbolt in response to operation of the second rotary control when the latch is retracted by the second rotary control. The link is configured to move along a linear path normal to the movement of the deadbolt and the door latch and to contact the primary cam mechanism upon the link movement to affect deadbolt retraction and extension. A lever may be used to retract the latch in response to rotation of the first rotary control in a first rotational direction when the deadbolt is retracted by the first rotary control.

摘要： A door latch system comprises an interchangeable latch assembly for securing a door to a door frame. The interchangeable latch assembly comprises a head and a latch mounted to the head. The latch is moveable between latched and unlatched positions. A driven member is operatively connected to the latch, the driven member moveable to latch or unlatch the latch. The door latch system further comprises a universal actuating assembly removably couple-able to the interchangeable latch assembly. The universal actuating assembly comprises a mounting bracket and a driving member releasably coupled to the driven member. Actuation of the universal actuating assembly translates the driving member and the driven member, moving the latch to the unlatched position. A first interchangeable latch assembly may be swapped with a second interchangeable latch assembly without requiring modification of the universal actuating assembly.

摘要： Disclosed is a Sleeve Stop Lock that is a portable, removable, non-damaging door lock that can be used to secure almost any inward swinging door from the outside. The apparatus consists of three components: a sleeve, a stop, and a lock. The “sleeve” component fits around the edge of a door. It is installed while a door is open. With the door closed, the “stop” makes contact with the door frame once attached to the sleeve thus preventing the door from swinging inward. The “lock” mechanism then securely binds all of the components together. The combination of these three elements (sleeve, stop and lock) prevent potential intruders (including housekeeping) from entering and invading the privacy of an unoccupied room.
