A handle-equipped lock. The lock comprises a latch bolt, a lock housing, and a release mechanism inside the lock housing. The handle includes handgrip, a spindle sleeve contiguous with the handgrip, and a polygonal shaped spindle, which has a part of its length inside the spindle sleeve and which is dimensioned to extend to an engagement with the lock's release mechanism. The shaped spindle, or a part thereof, is adapted to be manipulated inside the spindle sleeve between an unlocking position and a locking position. In the unlocking position, the shaped spindle extends to the lock's release mechanism and in the locking position it does not extend. The shaped spindle and the spindle sleeve are provided with locking means for securing the same relative to each other in said locking position, wherein manipulation of the shaped spindle is prevented. Alternatively, a continuous shaped spindle extends through the lock and the handle is capable of being manipulated relative to the shaped spindle between an unlocking position and a locking position.

A door lock has an inner door assembly, an indoor doorknob assembly, and an outdoor doorknob assembly. The inner door assembly has a locking assembly casing. The indoor doorknob assembly has a positioning resilient component located in the locking assembly casing and configured to switch the door lock between a locked state and an unlocked state. The door is provided with enhanced protection by enclosing the positioning resilient component in the locking assembly casing, so the safety is further improved.

Systems and apparatuses include a lock including a shackle movable between an unlocked state and a locked state, an electronically actuated blocker selectively engaged with the shackle to inhibit movement of the shackle from the locked state to the unlocked state, the blocker movable between a key override disabled position, a key override enabled position, and an electronic unlock position, and a key cylinder structured to move the shackle to the unlocked state when the blocker is in the key override enabled position.

A gravity gate latch that is sized and configured to be positioned in the gap between the free end of a gate and a stationary object when the end of the gate is adjacent the stationary object to automatically engage a strike member on the gate. The gate latch has a pair of side plates that are spaced apart to define a space that encloses a lever actuating mechanism and a hook plate. The hook plate has a hook member that engages the strike member of the gate. The lever actuating mechanism has a pair of lever arms, which can be accessed from either side of the gate, that move the hook plate upward to disengage the strike member. A lock receiving member at the bottom of the gate latch receives a padlock to lock the gate latch. The padlock can also be accessed from either side of the gate.

A gravity gate latch that is positioned near the free end of a gate to automatically engage a strike member. The gate latch has a pair of side plates that are spaced apart to define to enclose a hook plate and a sliding mechanism. The hook plate has a hook member that engages the strike member of the gate and a slot that engages the sliding mechanism to allow the hook plate to move upward and downward between the two side plates. The side plates define an enlarged latch mouth that receives the strike member. The hook member has an elongated edge to be hit by the strike member to lift the hook plate to allow the strike member to pass through the latch mouth and an enlarged area that is hit by the strike member to close the hook member to trap the strike member in the gate latch.

In combination: an over-the-road vehicle with a frame bounding a cargo space and at least one door having inside and outside surfaces and a peripheral edge; and a first locking assembly connected to the vehicle. The first locking assembly extends in an inside to outside direction over at least a portion of the thickness dimension of the peripheral door edge and so that a first portion extends to beyond the outside door surface. The first portion of the first locking assembly is configured to be engaged by a locking device that acts between the first locking assembly and another component to maintain the first door in the closed position. The first locking assembly is configured so that a region of the first portion is locally strengthened in a manner to resist severance and/or bending.

A lockout device is able to secure a door on a panel. The lockout device includes a housing and a flexible line. The housing has a first mounting portion adapted for securement to one side of the panel and the flexible line has on one end thereof a second mounting portion adapted for securement to another side of the panel from the first mounting portion. The housing further supports at least one line engagement element and the flexible line extends through at least a portion of the housing including the at least one line engagement element for selective engagement therewith. In use, the mounting portions may be affixed or attached to opposing sides or edges of the panel, the flexible line drawn taut, and the line engagement element(s) of the housing used to engage the flexible line to hold it in positon with respect to the housing.

A door hasp lock includes a first lock plate having a first flange and a first shield. A second lock plate is detachably engaged with the first lock plate and has a second flange detachably engaged with the first flange. The second lock plate has a third flange. The first lock plate and the second lock plate are engaged and disengaged when disposed at an operating locked state and a non-operating unlocked state, respectively. The third flange is spaced apart from the first flange and the second flange while the door hasp lock is disposed at both the operating locked state as well as the non-operating unlocked state. The third flange may be attached to either the first lock plate or second lock plate and has at least one feature that permits the third flange to break away from the second lock plate when tampered by an unauthorized user.

A tamper-evident securement device for use in securing closed a drawer of a furniture, comprising: a flexible extending closure member comprising an at least partially flexible attaching portion disposed within the furniture, and a flexible locking portion comprising a distal end section that traverses a gap between the drawer and a drawer opening when the drawer is closed, and provides an aperture that is disposed outside the furniture; and a securement member disposed within the furniture that attaches the extending closure member to an inner surface of a top side of the furniture; wherein a lock device can be inserted through the aperture of the flexible locking portion. The tamper-evident securement device may employ a shield plate. For installation of the tamper-evident securement device, an implement may be utilized.

A lockout system includes a hasp assembly and a plurality of tags. The hasp assembly has a back plate defining slots each sized and shaped to receive a tag. The back plate and tags each have openings that align when a tag is received in a slot. A first hasp portion has a first loop portion and a second hasp portion has a second loop portion. The first and second hasp portions are rotatable with respect to one another such that moving the lockout system has both an unlocked position and a locked position associated with an open position and a closed position. In the closed position, the first and second hasp portions complete and define a closed loop, where one or more tags can be installed in slots preventing further movement from the closed position.
