A manually activated locking device is provided to inhibit and restrict an entry/exit door from opening either outward or inward or both, as installed. In one aspect, the device that can be set from inside the room to be protected from threats or intrusion. In one aspect, the locking device is designed to be tamper-proof from outside the room yet allows access by authorized individuals thereby creating a secure but accessible safe zone for individuals or property inside the zone. In one aspect, the activated locking device may be mechanical system which may prevent hacking on the locking device.

Tilt latch apparatus and sashes incorporating the same are described herein. The tilt latch apparatus tilt latch apparatus may provide a convenient mechanism for a user to release the tilt latches on a sash with one hand while controlling movement (e.g., rotation) of the sash with another hand.

A cabinet locking device includes a cabinet body, a plurality of movable storage devices, a plurality of locking devices, and a driving device. The driving device is interlocked with the locking devices via a plurality of drawstrings. Each locking device includes a sliding member, an interference member disposed on the sliding member, and a restriction mechanism for guiding the sliding member. The driving device can drive the sliding member to move to an engaging portion or a released position. When the sliding member is moved to the engaged position, the interference member interferes with an engaging portion of the corresponding movable storage device such that the movable storage device cannot be opened. When the sliding member is moved to the released position, the interference member does not interfere with the engaging portion such that the movable storage device can be opened.

The present invention provides a resistant lock for locking doors, having a locking mechanism that enable locking the door in any direction without any modification or adjustment thereof, and that provide improved security.

A bi-fold door is opened with a lift assembly having a plurality of straps attached to power driven lift drums. A latch assembly retains the closed bi-fold door secure to side columns of a building. The latch assembly has a latch strap attached to a latch drum that accommodates the latch strap to hold the closed bi-fold door in contact with the side columns of the building. A floor anchor assembly anchors the bottom of the closed bi-fold door to the floor below the closed bi-fold door to stabilize and inhibit bending and deformation of the bi-fold door frame.

A window assembly is disclosed including a window casing; a sash assembly slidably mounted within the window casing, the sash assembly including first and second stiles extending between first and second rails; a first tilt latch assembly mounted in the first stile; a second tilt latch assembly mounted in the second stile; and a sash lock mounted to the first rail, the sash lock being operably connected to the first and second tilt latch assemblies to operate the first and second tilt latch assemblies between a latched position in which a latch member of each of the first and second tilt latch assemblies engages with the window casing assembly and an unlatched position in which the latch member of each of the first and second tilt latch assemblies is disengaged with the window casing assembly.

The present invention is an improved door barricade having a pivoting locking arm which drops into a floor hole to lock a barricade in place. In this invention, a system of single motion egress is taught which allows the barricaded door to be opened by the door knob or other exit means.

A foldable pet apparatus has a rigid platform member, a rigid barrier member, and a support member. The rigid barrier member is attached to one end of the rigid platform member by a hinge. The support member is attached to the rigid platform member at its other end with a hinge. The support member may be attached to a vertical wall below a pet door opening. When the foldable pet apparatus is in a deployed position, the rigid platform member provides a place for a pet to stand after it passes through the pet door. The rigid barrier member prevents the pet from going straight off of the end of the rigid platform member. The pet must turn to the right or left to leave the platform. When the foldable pet apparatus is in the collapsed position, it blocks the pet door opening.

A latch mechanism having an adjustment mechanism that adjusts the distance to which a latch bolt extends into a mating recess. The adjustment mechanism may include a driver component and a driven component. Rotation of the driver component about a first axis may displace the driven component, thereby causing the position of the latch bolt to be adjusted along a second axis that is non-parallel to the first axis. According to certain embodiments, the first axis is perpendicular to the second axis. The latch mechanism may also include an inner housing that is displaced as the latch bolt is extended into, and retracted from, a mating recess in an adjacent structure. Further, the position of the inner housing may remain generally static as the position of the latch bolt is adjusted along the second axis via operation of the adjustment mechanism.

A lever gate latch pull system with a pivoting T-shaped lever has two aligned first and second arms affixed to a swinging base foaming a T with a pivot hole proximate the junction of the aligned first and second arms and the swinging base. The T-shaped lever is pivotally affixed to a fence post to pivot the arms up and down as the swinging base correspondingly moves in a side to side upward arc. Affixed to the end of the swinging base is a weighted chain extending to and secured via a fastener to the free end portion of the pivotal latch lever of the gate latch in the resting position. The weighted chain provides pressure on the pivotal latch lever to stay in the latched position until lifted by the T-shaped lever. In operation, when the T-shaped lever handle first or second arms are positioned just beneath the top of the fence and depressed, they pivot the swinging base in an upward arc to pull the chain up to unlatch the gate latch to open the gate from either side.
