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.

A sash window restrictor (20) has a housing (22) which is to be let into a vertical frame member (10) of one sash (normally the upper, outer sash) of a window, at a position, say, 10 cm above the top rail of the lower sash when the windows are closed. A tab (24) is mounted in the housing and can be retracted into the housing or extended from the housing. A mechanism acts between the tab and the housing and allows the tab to be pressed into the housing and held in the housing for a period of time before the tab is released to allow the tab to extend. With the tab extended, the lower sash (12) can be lifted until it reaches the tab (24) but no further, so that a 10 cm gap will be opened at the bottom of the window.

A gravity-actuated latch mechanism is provided. The gravity-actuated latch mechanism may include a strike attached to a lid of a container and a latch body attached to an inside wall of the container. The latch body includes a housing and a catch accessible from outside of the housing, wherein the catch engages and disengages with the strike. The latch body includes a lever having a lever arm moveable between an engaged and disengaged position. The engaged position is engaged with the catch and the disengaged position is disengaged with the catch. The latch body also includes a latch actuation ball housed in an elongated passage within the housing. The lever arm of the lever extends into the elongate passage, allowing the latch actuation ball to apply force to the lever arm to move the lever from the engaged to the disengaged position in response to tipping the container for dumping.

A double lock, dual action gravity latch device to secure a gate in a closed position comprising a latch assembly including a pivotal latch member movable between a latched and unlatched position, a keeper assembly including a striker pin to maintain the gate in the closed position when the pivotal latch member in the latched position, a latch lock assembly including a lock assembly with a first lock and a second lock each independently movable between a locked position and an unlocked position disposed on opposite sides of the gate to selectively move a lock subassembly from a locked position to an unlocked position when either the first lock or second lock is moved from the locked position to the unlocked position, and move the lock subassembly from the unlocked position to the locked position when the unlocked lock is moved from the unlocked position to the locked position and a first latch actuator and a second latch actuator each movable between a first position and a second position disposed on opposite sides of the gate to selectively move the pivotal latch member when either the first lock or the second lock is moved from the locked position to the unlocked position moving the lock subassembly from the locked position to the unlocked position such that when either the first actuator assembly or the second actuator assembly is moved from the first position to the second position the pivotal latch member is moved from the latched position to the unlatched position to allow the gate to be opened.

A double lock, dual action gravity latch device to secure a gate in a closed position comprising a latch assembly including a pivotal latch member movable between a latched and unlatched position, a keeper assembly including a striker pin to maintain the gate in the closed position when the pivotal latch member in the latched position, a latch lock assembly including a lock assembly with a first lock and a second lock each independently movable between a locked position and an unlocked position disposed on opposite sides of the gate to selectively move a latch blocking assembly from a latch blocking position to a latch unblocking position when either the first lock or second lock is moved from the locked position to the unlocked position and move the latch blocking assembly from the latch unblocking position to the latch blocking position when the unlocked lock is moved from the unlocked position to the locked position.

A securement system for securing one or more calf hutches is provided. The securement system includes latch assemblies and a line. The latch assemblies are configured to be attached to the calf hutches and comprise receiver flanges and latch arms. Each receiver flange includes a vertically-extending plate defining a locking slot with an open end. Each latch arm may be shifted between a closed position in which it blocks the open end of the locking slot and an open position in which it does not block the open end of the locking slot. Each latch arm is biased to the closed position.

The present invention provides a locking device for a waste container that keeps the lid of the container closed when the container is knocked over on its side, as may arise from a sudden jerking or jarring motion, such as by impact with the ground, to prevent spillage of its contents. The locking device allows the lid to open automatically when the waste container is tipped over by a dumping operation. The locking device includes a sliding block slidable between a locked position and an open position, and a pendulum weight detachably attached to a magnet, when detached from the magnet, the pendulum weight blocks the sliding block from sliding to the open position. When attached to the magnet, the pendulum weight allows the sliding block to slide to the open position.

A door security device for an out-swing door includes a mounting plate secured to the door, a hinge pin assembly supported by the mounting plate proximate the door outside edge, a clasp swing plate secured to the hinge pin assembly for pivotal movement between unlocked and locked positions, a door frame anchor bolt received in a clasp cut-out of the clasp swing plate captured behind an enlarged anchor bolt head in the locked position in a lowermost position of the clasp swing plate, the clasp swing plate biased by force of gravity to the lowermost position, and the mounting plate having a first receiver top surface at the hinge pin vertical axis, the first receiver top surface defining the uppermost position of the clasp swing plate in an unlocked position parallel to the mounting plate and defining the lowermost position of the clasp swing plate in the unlocked position perpendicular to the mounting plate.

A securement system for securing one or more calf hutches is provided. The securement system includes latch assemblies and a line. The latch assemblies are configured to be attached to the calf hutches and comprise receiver flanges and latch arms. Each receiver flange includes a vertically-extending plate defining a locking slot with an open end. Each latch arm may be shifted between a closed position in which it blocks the open end of the locking slot and an open position in which it does not block the open end of the locking slot. Each latch arm is biased to the closed position.

Emergency access device for a vehicle opening leaf, including:—a graspable pull rod that is movable between a retracted position and a deployed position;—a retention needle that is movable transversely to the pull rod between a position for blocking the pull rod in its retracted position and a position for releasing the pull rod;—an electric ejector designed to release the pull rod;—a mechanical ejector designed to release the pull rod; the pull rod including an oblique path designed to cause the retention needle to move from its blocking position to its releasing position during a movement of the pull rod in translation.
