Disclosed is door guardrail. The door guardrail includes a door guardrail body having an opening; a movable baffle movably mounted on and movable relative to the door guardrail body to open or close the opening; and a locking device, arranged on the movable baffle or the door guardrail body; and wherein the locking device is capable of limiting or releasing the movement of the movable baffle relative to the door guardrail body.

The invention relates to a device (200) for locking a door, which comprises: a bolt (40) comprising a bar (52) configured to engage in a housing secured to the frame (80) accommodating the door and a pusher means secured to the bar (41) and spaced apart from the bar by a stem and in which the bolt is positioned on the door at a height relative to the foot of the door of between thirty and eighty centimetres, such that the bar of the bolt can be engaged with or disengaged from the housing secured to the frame by pressure applied by a user's knee against the pusher means.

An adjustable door lock may include a catch plate adapted to be secured adjacent to the door. A plurality of catch brackets may be connected to the catch plate. A catch may be adjustably connected to the catch plate and interfitted through the catch brackets. Such a catch preferably has a linear channel formed therein. A door plate may be disposed adjacent to the catch plate and adapted to be secured to the door. A locking bolt may further be housed within the door plate and may be linearly reciprocated along a first linear path passing through the door plate and the linear channel. In this way, the catch may be automatically adjusted along a second linear path orthogonally registered relative to the first linear path such that the linear channel automatically becomes axially aligned with the locking bolt as the locking bolt ingresses and egresses the catch.

A latch mechanism includes a main body engagement unit arranged in a main body having an opening/closing body that opens/closes, and opening/closing body engagement unit arranged in the opening/closing body to engage with the main body engagement unit when the opening/closing body is closed, in which the main body engagement unit is configured to include a first engagement body having a pair of first top portions displaced in a direction orthogonal to a closing direction of the opening/closing body, the opening/closing body engagement unit is configured to include a second engagement body having a pair of second top portions respectively coming into contact with the pair of first top portions, and the second engagement body has a first slope that applies a force in a direction to open the opening/closing body to the second engagement body in a state where the other first top portion of the pair of first top portions is in contact with the second top portion, when one second top portion of the pair of second top portions comes into contact with one first top portion of the pair of first top portions while the opening/closing body is closed.

A cabinet lock includes a latch configured to translate between extended and retracted positions and a lever configured to rotate between engaged and disengaged positions. The latch may be coupled to the lever with a pin in a corresponding slot. When the lever is in the disengaged position the latch may be in the extended position and when the lever is in the engaged position the latch may be in the retracted position. The lever includes a ferromagnetic portion responsive to a magnet within a threshold distance, where the presence of the magnet moves the lever to the engaged position.

A sliding bolt latch as disclosed herein is convenient to use and more reliable than counterpart door locking mechanisms of the prior art. A user may open and close a door with only one hand, but the present mechanism requires both a rotational movement and a translational movement of elements against a biasing force. Such requirement makes opening doors much more difficult for livestock confined to spaces by the closed doors. Also, the biasing of elements into the locking state makes embodiments of the invention less likely to unlock inadvertently in the presence of ambient vibrations.

Latch assemblies are provided with a paddle lever having an outwardly extending actuator flange and a rotary actuator plate which includes a fixed actuator pin extending outwardly from the actuator plate and adapted to being operatively engaged with the actuator flange of the paddle lever when manually moved into the unlatched condition thereof. At least one pair of arcuate spirally patterned and circumferentially separated cam slots are defined in the rotary actuator plate such that a latch pin associated with a latch bolt is operatively received within a selected one of the cam slots. Movement of the paddle lever from the latched condition into the unlatched condition thereof responsively engages the actuator flange with the actuator pin thereby causing rotation of the actuator plate about a rotary axis thereof and movement of the latch pin within the selected one of the cam slots whereby the latch pin is retracted to unlatch a moveable component from a fixed component.

A door mullion receptacle box assembly includes a toe plate, a channel box and block components. When a mullion is removed from a building/room opening, the toe plate may be fixed in the mullion receptacle box thus creating a uniform threshold across the width of the door openings. Using the assembly described herein, however, there are no large diameter holes in the top of the toe plate and no projections into the opening that could be a trip hazard. The present assembly replaces traditional fixed sill blocks mounted to the floor, or to the top of a threshold to anchor the bottom of conventional mullions. A typical mullion is locked in place with a lock at the top of the mullion. When installed, this mullion is placed over the sill block at the sill and tilted into place and locked into a header block at the top of the mullion. However because the components of the conventional sill blocks project up into the mullion from the thresholds, they become a trip hazard and a liability when the mullion is temporarily removed.

A low profile actuating window lock for casement windows having a longitudinal slot in a sidewall of the casing for the lock, wherein a fork component translates within the slot in a direction perpendicular to an axis of rotation of the handle and the handle rotates along a plane perpendicular to the fork component, the handle pivotable about a restrictor arm that pivots relative to the casing, allowing the handle to rotate fully from the locked position to the unlocked position with low clearance from the window frame. The pivot points of the handle and restrictor arm configuration allow for an over center linkage that prevents back driving the casement window lock.

A retention bracket configured for use with a latch mechanism including a laterally extending housing. The retention bracket includes a first wall, a second wall, a collar, and a deformable section. The first and second walls are longitudinally offset from one another and are structured to receive the housing therebetween. The collar extends longitudinally outward from one of the walls and defines an opening having an effective diameter. The deformable section has a natural state in which the effective diameter is a first diameter, and a deformed state in which the effective diameter is a second diameter greater than the first diameter.
