The present disclosure relates to a connecting device, which includes a clamping mechanism, a transverse arm mechanism, a main arm member and a connecting mechanism that are sequentially connected. The clamping mechanism includes a clamping block and a fixing member. The transverse arm mechanism includes a mounting base, a positioning member and a fastening member. The fixing member connects the clamping block and the mounting base. The positioning member is connected to one end of the mounting base away from the clamping mechanism. The fastening member connects the positioning member and the mounting base. The main arm member extends through the mounting base. The connecting mechanism is provided with a connecting rod connected to the main arm member.

A window frame assembly for installation within a garage door having front and rear exposed surfaces and one or more window openings. The assembly includes front and rear window frame members which are installed within the door openings in the garage door. The front and rear members are brought toward each other to sandwich the borders of each of the window openings while also capturing an associated transparent pane. A series of fastening members are used to hold the front and rear frame members securely against each other. The front and rear window frame members are made of synthetic polymeric starting stock starting materials which, together with the transparent panes, are able to withstand hurricane force winds and associated blowing debris.

An entryway door is capable of withstanding direct hit hurricane loads and subsequent water surge for long periods. A door slab is formed of reaction-injected-molded aliphatic polyurethane having an outward face, and inward face, and a peripheral edge, with a window opening formed therethrough. A ballistic glass-clad polycarbonate laminate window is provided which sized larger than the window opening. The laminate window having a central light transmissive region and an outer boarder region. A primer border is applied to the outer boarder region of outward and inward faces of the laminate window. The door slab is reaction-injected-molded about the laminate window with the outer boarder region extending into and is bonded to a portion of the door slab forming the window opening. The preferred door in mounted to a structure in an outwardly opening manor with a seal entrapped between the periphery of the door and a door jam.

A closing body allows closing and opening an access opening or a passage of a room in case of a pressure difference between an interior and exterior of the room. A closing fitting set and a door leaf are disclosed, by means of which closing fitting set and door leaf a closing body can be formed. The closing body is in the form of a pivotable door, a pivotable window or a pivotable flap. A valve device is provided on the closing body, which valve device effects a temporary pressure equalization during the opening or closing of the closing body. The valve device is in the form of a valve flap, and a release mechanism is provided, which opens the valve device. A locking fitting is provided for the closing body, and the release mechanism is coupled, for actuation, to the locking fitting of the closing body.

An explosion-proof housing having a cover arrangement which includes two or more covers. The covers are adjacent to a flameproof gap in the housing body (11). A flameproof gap is likewise arranged between the individual covers. Special seals, more particularly in the form of a butt joint closure, are arranged on the remaining butt joints or other gaps and through-holes.

A bi-fold door assembly has an upper door section and a lower door section connected by a hinge such that the upper and lower door sections are movable between a closed position spanning the door opening and an open position in which the upper door section is oriented transversely to the door opening and the lower door section is folded upwardly towards an inner side of the upper door section. A truss supported along the inner side of one of the upper and lower door sections is movable relative to the door sections between a first position in which the truss stiffens the door assembly against bending corresponding to the closed position of the door sections and a second position in which the truss member is reduced in overall width relative to said one of the upper and lower door sections in a normal direction to the door sections.
