An opening/closing body locking device for an opening/closing body that is openably/closably mounted to an opening portion of a stationary body, the locking device including locking portions provided on both lateral sides of the opening/closing body, a pair of link rods that are mounted to the stationary body, and are interlocked with each other to slidably move so that hook portions at distal ends thereof engage and disengage the locking portions, a biasing unit that biases the link rods in directions that the hook portions of the link rods engage the locking portions, and an operating member that causes the hook portions of the link rods to slide in directions that the hook portions disengage the locking portions against biasing force of the biasing unit, pressing members that are provided on the both lateral sides of the opening portion of the stationary body.

A sliding privacy door and lockset system for doors of the types generally known as “barn doors” and/or “pocket doors”, due to these doors being slidably mounted on a rail or rails positioned above a doorway or otherwise in or near a doorway. The present invention includes a lockset comprising a strike plate mounted to a door, and a lockset sub-assembly mounted to a door jamb. The lockset sub-assembly includes an actuating arm connected axially to a rotatable extension of a thumb turn. During operation, the distal end of the actuating arm rotates from an unlocked position to a locked position, that is, the distal end of the actuating arm rests within a slot in the strike plate. The strike plate may include a bump to limit the actuating arm's rotation, and a flush pull handle comprising an opening configured to provide a user's hand(s) with a place to grip.

A gate latch pull system for a swinging gate and gate post. A gate latch with pivotal latch lever is mounted on a gate post and a latch bar on an inside edge of a swinging gate. A T shaped lever with first and second lever arms and a swinging base is pivotally mounted on the gate post above the gate latch. A vertical linkage connectable between bottom of swinging base and top of the pivotal latch lever, with the linkage adjustable in length during connection of the base and the latch lever such that when the latch lever is in a latched position and the swinging base is vertical, the linkage has flexibility, slack and weight enough to provide additional downward weight bias to pivotal motion of the latch lever.

An automatic hatch assembly for bulk material containers includes a hatch cover which covers a fill opening of the container, and may be retrofitted to existing containers equipped with a conventional hatch cover. A drive unit is operable to open and close the hatch cover, and a locking assembly actuates an extendable lock member. Optionally, a pneumatic seal is provided within the cover for sealing the container from the outside environment. The locking assembly is adapted to resist opening forces applied to the cover, such as when the container is pressurized, and a sequencing controller may be provided to facilitate automated operation of the opening/closing, locking/unlocking, and/or sealing/unsealing of the hatch cover.

A security system for a building includes a plurality of lock modules. Each lock module is associated with a particular door and has an unlocked position and a locked position. Each lock module includes a lock bar, an actuator, and a controller. The lock bar has a first position that allows the particular door to open and a second position that extends from a door frame, a wall, or a floor surface adjacent to the particular door to prevent the particular door from opening. The actuator moves the lock bar between the first and second positions. The controller is operably connected to the actuator and transmits a door status signal that uniquely identifies the particular door. A lock module command signal received by the plurality of lock modules directs the plurality of lock modules to reposition to either the unlocked position or the locked position.

Systems, methods, and apparatus are disclosed involving a door blocking apparatus to reduce a likelihood of, and possibly prevent, opening of a door by unauthorized personnel. The apparatus may be networked in a security system and may be connectable to an online security platform. In a particular embodiment, an embodiment of the invention may include a security system involving a plurality of door locations having a plurality of networked door blocking apparatus. Each door blocking apparatus may include a door blocking mechanism operable by a user on a safety side of a door, such as having the user rotate an apparatus handle that rotates the door blocking mechanism between a non-blocking position and a blocking position. In the non-blocking position, the door blocking apparatus does not block the door from opening and closing. In the blocking position, the door blocking apparatus blocks the door from opening and from closing completely.

An apparatus for locking a panel to a strike jamb includes a synchronous displacement mechanism associated with a locking element (108) which is responsive to part of a closing motion of a panel (104) from an open position towards a closed position to initiate a motion of locking element (108) towards the locked position during the closing motion of the panel prior to the panel reaching its closed position. The synchronous displacement mechanism preferably has a “deadlock state” when the locking element is in the locked position which prevents displacement of the locking element towards the unlocked position.

Apparatuses, methods, and systems for providing a locking apparatus for resisting movement of an openable element are described. The locking apparatus includes a body, an actuator, a lifting member, at least a portion of the lifting member being configured to be raised or lowered relative to the body according to an output of the actuator, the lifting member comprising a contact surface configured to restrict movement of the openable element, and a strap coupled to the body and to the lifting member, the strap configured to permit the lifting member to flex based at least in part upon contact between the lifting member and the openable element and to transfer energy received at the lifting member into the body of the locking apparatus into a surface to which the locking apparatus is mounted.

A hasp assembly (200), having: a hasp (302) that engages a staple (404); an actuator (320) that retains the hasp in an engaged position; a first passage (410) and a first element (802) therewithin; and a second passage (412) and a second element (418) therewithin. A linear length of the second passage (L2) is greater than a linear length (L1) of the first passage. When in a tilted orientation (800) the first element is urged by gravity along the first passage and impact of the first element on the actuator releases the hasp, and the second element is urged by gravity along the second passage toward a terminal position (712) where the second element blocks the first element.
