A locking system includes a tamper-resistant lock and key. The tamper-resistant lock can include a cylindrical lock body with an upper portion having an engagement surface defining a pattern of engagement features, a housing, and a hidden component sized and shaped to fit within the housing that includes an internal lock base into which the cylindrical lock body fastens and a padlock pin configured to secure the internal lock base to a hasp or staple. The key operable for use with the tamper-resistant lock can include a cylindrical key body defining an engagement cavity configured to receive the engagement surface of the cylindrical lock body, a set of complementary engagement features, a plurality of retractable engagement members, and a retractable collar at least partially covering the cylindrical key body.

A strike plate assembly is repeatedly vertically and securely adjustable to serial secure positions on a door jamb for securing a bolt without loosening or removing the assembly's jamb attachment screws and without resetting its jamb attachment screws within new jamb holes.

A magnetically-triggered lock mechanism for interengaging two relatively movable components. The lock mechanism includes a bolt mounted within a first component composed of a first material and displaceable between retracted and extended positions to interengage with a second component when the first and second components are in a predetermined position relative to each other and the bolt is extended, and a magnetically-releasable latch mechanism positioned to latch the bolt in a retracted position, the latch mechanism including a first magnet and mounted for movement between a biased latch engaging position and a latch releasing position. A support collar composed of a second material having higher strength than that of the first material is disposed around the bolt between an inner casing and outer casing of the first component and is spaced from the bolt to allow for sliding movement of the bolt through the support collar as the bolt moves between the extended and retracted positions. The support collar absorbs and distributes to the inner and/or outer casing a load generated from the bolt as the bolt moves to the extended position through the support collar. A second magnet is positioned to displace the latch mechanism to the latch releasing position when the first component is in the predetermined position relative to the second component.

A gate-latching assembly is configured for utilization with a gate assembly. The gate assembly includes a stationary gate post configured to be mounted to, and to extend from, a working surface once the stationary gate post is mounted to the working surface, and in which the gate assembly also includes a movable gate door configured to be movable relative to the stationary gate post. There is provided a combination for utilization with the gate assembly. The combination includes any one of (A) a striker base assembly and a striker member, (B) a latch base assembly and a latch assembly, and/or (C) a striker base assembly, a striker member, a latch base assembly and a latch assembly.

A strike plate assembly is repeatedly vertically and securely adjustable to serial secure positions on a door jamb for securing a bolt without loosening or removing the assembly's jamb attachment screws and without resetting its jamb attachment screws within new jamb holes.

An adjustable-latch system including an adjustable-receiver assembly and an adjustable-striker-bar assembly. The adjustable-receiver assembly includes a receiver sleeve having a pair of oppositely-disposed channels formed therein and a receiver slidably disposed within the pair of oppositely-disposed channels. A first plurality of fastening members mount the receiver sleeve. The adjustable-receiver assembly further includes a receiver-sleeve cap slidably disposed within the receiver sleeve. The adjustable-striker-bar assembly includes a mounting plate having a striker bar extending laterally therefrom, a second plurality of fastening members for mounting the mounting plate, and a striker-bar cap slidably coupled with the mounting plate. A position of the adjustable-receiver assembly may be adjusted relative to the adjustable-striker-bar assembly without removal of the first plurality of fastening members. A position of the adjustable-striker-bar assembly may be adjusted relative to the adjustable-receiver assembly without removal of the second plurality of fastening members.

Leaf (4) of a sliding window (1) or sliding door, whereby this leaf (4) has a horizontal profile (13) and an upright side profile (12) perpendicular to the horizontal profile (13), whereby the horizontal profile (13) is provided with a lock plate (10) for a lock (9), whereby the leaf (4) is equipped with an adjustment mechanism to be able to adjust the position of the lock plate (10) in the direction (P) in which the horizontal profile (13) extends and to be able to secure the lock plate (10) to the leaf (4), whereby the adjustment mechanism can be operated from the side where the side profile (12) is located.

A magnetically-triggered lock mechanism for interengaging two relatively movable components. The lock mechanism includes a bolt mounted within a first component and displaceable between retracted and extended positions to interengage with a second component when the first and second components are in a predetermined position relative to each other and the bolt is extended, and a magnetically-releasable latch mechanism positioned to latch the bolt in a retracted position, the latch mechanism including a first magnet and mounted for movement between a biased latch engaging position and a latch releasing position in a non-common direction of movement of the bolt. An adjustable strike having an actuator portion including a second magnet is positioned to displace the latch mechanism to the latch releasing position when the first component is in the predetermined position relative to the second component, wherein the actuator portion is pivotable about a transverse axis of the strike body in response to magnetic communication between the first and second magnets to maintain the actuator portion within close proximity to the latch mechanism.

An actuator controlled electric strike for operating in conjunction with a latch of a lockset. The strike comprises a keeper support bracket movable between first and second positions. When the bracket is in the first position a keeper is held in either a locked or unlocked position, and when the bracket is in the second position the keeper is movable to the other position. An actuating mechanism is operatively connected to the bracket and is configured to allow the bracket to move between the first and second positions. First and second biasing mechanisms apply a net force to the bracket. The first biasing mechanism applies a first force to the bracket in the first direction, and the second biasing mechanism applies a second force to the bracket in the second direction. When the bracket is in the first position, the net force of the biasing member is approximately zero.

A top pull gravity latch device to selectively secure a gate in a closed position to block the opening or portal in a fence, wall or other barrier comprising a latch assembly including a latch actuator assembly, intermediate pull actuator assembly and pivotal latch member each movable between a first and second position and a keeper assembly including a striker pin to selectively engage the pivotal latch member to move the pivotal latch member from the first to second position when the keeper assembly is moved from the second to first position and back to the first position wherein the gate is securely closed when the latch actuator assembly, intermediate pull actuator assembly, pivot latch member of the latch assembly and the striker pin of the keeper assembly are all in the first position and wherein the intermediate pull actuator assembly is moved from the first to second position to move the pivotal latch member from the first to second position clearing the striker pin of the keeper assembly to be moved from the first to second position to allow the gate to be opened.
