An extendible barricade including a housing having a first panel located within the housing that is extendable from the housing, a second panel located within the housing that is extendible from the housing, wherein the housing is releasably attached to an overhead door by means of an attachment assembly. Furthermore, an associated method is also provided.

A gate made from light weight tubular material with creates a framework upon which slats are attached. Slats are capable of being attached on the front of the gate or being passed through slots in the tubular material. The framework is capable of being reinforced with the use of additional tubular material or braces in the corners, as well as additional horizontal, vertical, or diagonal supports.

A mounting system and method for security screens for use with double-hung windows and other windows having an integral screen track is disclosed. The mounting system and method according to the present invention reduces materials cost for manufacture of security screens while improving aesthetics of the installation, and permits installation of security screens either at the construction site or during window manufacture, while preserving the window manufacturer's warranty.

The invention belongs to the technical field of protective articles for infants and young children, and particularly relates to a fence gate limiting mechanism, a fence gate assembly and a fence gate limiting method which can be suitable for protective devices such as fence gates. In the invention, the traditional dual-operation unlocking is transformed into two-stage unlocking, which eliminates the occurrence of unauthorized opening of the gate assembly by infants and young children. The invention also provides a novel connection mechanism with desirable structural strength and connection strength, which reduces the labor intensity and improves the assembly efficiency in production, assembly and maintenance.

A design for a universal telescoping swing gate can be sized to obscure a wide range of openings while accommodating a multitude of installation options to make the gate versatile under many conditions. The swing gate can have a frame with a pivot member rotatable about a mounting seat between an open configuration and a closed configuration. The frame can have first and second telescoping members adjustable along an extension axis between a collapsed state and a fully extended state for changing the frame length so the gate can be quickly furnished to different sized openings. The gate can be spring loaded to bias the frame to a nominally closed position to reduce the chance for human error among workers. The gate can also be sized to have the structural rigidity to comply with OSHA requirements for handrails and guardrails around a walking-working surface.

An opening/closing direction restriction mechanism for a manual shutter device and an opening/closing direction restriction mechanism for a suspended sliding door device This opening/closing direction restriction mechanism is provided with: a flange fixedly mounted on a fixed shaft; a bracket which is loosely fitted to the fixed shaft and can be integrally rotated with a winding member; and a two-way clutch which can be switched between a reverse rotation inhibited state in which the revolution of a planetary external gear along a winding direction of the winding member is allowed and the revolution of the planetary external gear along an unwinding direction is inhibited, and a forward rotation inhibited state in which the revolution of the planetary external gear along the winding direction of the winding member is inhibited and the revolution of the planetary external gear along the unwinding direction is allowed.

A fireproof shutter includes a frame having an opening through which a transport rail for movement of a transport vehicle passes, the opening being divided into an upper opening and a lower opening based on the transport rail, an upper door mounted on the frame and configured to open and close the upper opening, and a lower door mounted on the frame and configured to open and close the lower opening.
