Apparatus and methods for assembling, installing, and operating a manually operated gate (e.g., a safety gate). The manually operated safety gate can include a gate frame and a spring assembly. The gate frame can include a proximal upright member, a distal upright member, an upper arm, and a lower arm. The proximal upright member can be anchored to a stationary surface. The upper arm and lower arm can be pivotably coupled to the proximal upright member and distal upright member to form a parallelogram. The manually operated gate can be configured to pivot between self-close position and a closed position at a constant angular velocity. A kit can contain the required structural components and instructions and can be used to assemble the manually operated gate assembly.

A safety gate has a gate body and two first locking units. The gate body has two first connecting elements. The two first locking units are respectively mounted on two opposite sides of a door frame. Each first locking unit has a second connecting element and a blocking element. When the safety gate is closed, each of the first connecting elements is connected with a respective one of the second connecting elements. Each blocking element has a blocking position for blocking a corresponding first connecting element to prevent the corresponding first connecting element from being disengaged from the second connecting element and a pressed position to allow-the corresponding first connecting element to detach from the second connecting element of the first locking unit.

A retractable door sill, including: a mounting base, the mounting base including an upper fixing base and a lower fixing base; a rotating drum, the rotating drum being arranged between the upper fixing base and the lower fixing base, a partition cloth, a torsion spring being configured to make the rotating drum rotate in one direction around its axis, the rotating drum wind up the partition cloth; and an adjusting device, the adjusting device comprising an adjusting rod and an adjusting mechanism, one end of the torsion spring being connected to the rotating drum, the other end of the torsion spring being connected to the adjusting rod of the adjusting device, the adjusting mechanism being configured to enable the adjusting rod to rotate unidirectionally around its own axis, and the adjusting rod being configured to change a torsional deformation of the torsion spring through its own rotation.

A retractable, coilable, security barrier screen easily mounted around a door, window or other building opening such as a hallway entrance. The barrier is designed to withstand considerable forces from blunt force strikes, bullets and edged weapon slashing. As such, it has a strengthened spool tube, novel security barrier attachment methods, and redundant operational features such as dual (top and bottom spool locks), quad spool locking pins and a dual attachment for the fabric security barrier to the screen lock strip that includes both gluing and plate riveting.

The present gate light apparatus includes an adapter bracket having a front side and a rear side. On the front side, the bracket engages a housing having a motion detector, photo sensor, and light source. On the rear side, the bracket engages two support members of a gate.

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.

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 reel locking device includes: a reel seat; a vertical reel rotatably connected to the reel seat and used for retracting and releasing a gate mesh; a synchronization member fixedly connected to one end of the vertical reel; an automatic locking mechanism that prevents the synchronization member from rotating freely and that includes a resettable manual unlocking slider; and an elastic pressing mechanism that obstructs the movement of the manual unlocking slider and that includes a pressing member that does not obstruct the movement of the manual unlocking slider after being pressed, and that when not pressed or after resetting obstructs the movement of the manual unlocking slider. A mesh type gate is further disclosed including the above reel seat on one side and a buckle seat on another side, where a free end of the gate mesh includes a pull ring for being fastened to the buckle seat.

The present soft barrier includes sheeting and a frame. The frame includes longitudinal and lateral support members. The sheeting is in a relaxed state when the lateral support members are in a retracted state. The sheeting is in a taut state when the lateral support members are in an extended fixed state. The sheeting may be in either the relaxed state or taut state when the longitudinal support members are in a retracted state or an extended state. A first adjustment mechanism for increasing or decreasing the longitudinal length of the barrier is a quick slide mechanism. A second adjustment mechanism for finely increasing or finely decreasing the longitudinal length of the barrier is a rotatable mechanism.

A barrier employed to keep children and/or pets in or out of certain areas in the house. The barrier includes four panels. Two main panels slide parallel to each other to lengthen or shorten the barrier as a whole. Two side panels stabilize the main panels and extend to the front and rear faces of the main panels to provide a self-supporting in-house barrier. Each of the panels includes a wooden frame. The wood lends less weight, less sharp edges, and more pleasing aesthetics than, for example, a metal gate. Legs are connected to the side panels to further stabilize the side panels and main panels.
