A doorway gate system for resisting being chewed by an animal includes a barrier that has a pair of gates and a lock. The gates are slidably coupled together such that the barrier is extendable to a selected width. In this way each of the gates is selectively extended across a doorway thereby inhibiting an animal from passing through the doorway. The lock retains each of the gates at the selected width. A protective coating is positioned on the barrier and the protective coating completely covers the barrier. The protective coating is comprised of a resiliently compressible material to resist is chewed by the animal thereby enhancing a service life of the barrier.

A security and escape apparatus for use with a window mounted in a wall at a position spaced above a support surface is disclosed. According to one aspect of the invention track members of a first bar section are S-shaped in cross-section so as to carry a second bar section thereon and thereby allowing the bar members of the bar sections to be uniform in length. According to another aspect a release mechanism comprises an abutting portion which is positioned beneath the bar sections to retain the sections across a window opening. The abutting portion is positioned horizontally outwardly of the bar sections such that the bar sections can extend to form a ladder beneath the window opening. According to another aspect the apparatus includes a window frame mounting arrangement cooperative with the obstructing position for resisting dismantling of the apparatus.

An improved barrel bolt assembly and extensible gate comprising the same wherein the assembly includes a washer having at least one inward or outward projection annularly disposed about an internal periphery thereof, a fastener having a head portion and a shank portion extending therefrom, and a barrel having a head portion and a boss portion extending therefrom, wherein the boss portion is operative to receive the fastener shank portion and the barrel boss portion further includes at least one inward or outward projection annularly and complementarily disposed and formed with respect to the inner periphery of the washer, to receive and mate with the washer, whereby the washer and barrel interlock to prevent rotational movement with respect to each other.

A barrier latch assembly having a housing including a first locking element, a second locking element, a trigger and a swing plate. The swing plate is coupled to the trigger and to the first and second locking elements. When the trigger is depressed, the swing plate pivots from an unlock position to a lock position over a rear side of the first and second locking element thereby blocking and preventing the first and second locking elements from being depressed inward.

A telescopic folding type pet cage door includes a lockset (1), a rotating handle (2), a locking rod (3) and guide rails (4). The pet cage door includes at least three folding units in a vertical direction, wherein the three folding units can be folded in sequence, and both ends of each folding unit are capable of sliding along the guide rails (4). The bottom folding unit is connected with a vertical lifting rod, a rotating handle (2) is disposed on the top of the lifting rod, a hook (2a) configured to hook the locking rod (3) is disposed on the end portion of the rotating handle (2), and when the hook (2a) hooks the locking rod (3), the lockset (1) carries out rotary locking on the rotary handle (2); and the lockset (1) is unlocked, the rotating handle (2) rotates, the hook (2a) is separated from the locking rod (3), the rotating handle (2) drives the lifting rod to move upwards or transversely, and the lifting rod drives the at least three folding units to be sequentially folded upwards or transversely.

A security window applied to a single window is applied to a previously installed single window so as to block an open space of the window and prevent entry by strangers and a person inside from having a falling accident. The security window can be separated from within a room as necessary, and thus movement of an object or emergency escape is facilitated. Meanwhile, the security window cannot be separated from outside the room, and thus intrusion by persons with malicious intent can be prevented from the onset.

Provided is an adjustable barrier having a central hinge having a cylindrical post and an axis of rotation; a first expandable section coupled to the cylindrical post of the central hinge by at least a first connector; and a second expandable section coupled to the cylindrical post of the central hinge by at least a second connector. At least one of the first and second expandable sections is configured to articulate around the axis of rotation of the central hinge forming an articulation angle between the first and second expandable sections.

A burglar trapping system includes a grill assembly having a collapsible grill door adapted to be operated in a collapsed condition and an expanded condition and a motor adapted to operate the collapsible grill door. A sensing module is configured to detect a pressure applied on an object and a communication unit is configured to receive the detected pressure from the plurality of sensors and/or a triggering input from a remote electronic device and generate an input based on one of the detected pressure and the triggering input. A control unit in communication with the communication unit is configured to receive the input from the communication unit and operate the motor to move the collapsible grill door in the expanded condition.

Provided is an adjustable barrier having a central hinge having a cylindrical post and an axis of rotation; a first expandable section coupled to the cylindrical post of the central hinge by at least a first connector; and a second expandable section coupled to the cylindrical post of the central hinge by at least a second connector. At least one of the first and second expandable sections is configured to articulate around the axis of rotation of the central hinge forming an articulation angle between the first and second expandable sections.
