Disclosed in the present application are a door leaf, and a door set comprising the door leaf. The door leaf having a first leaf portion and a second leaf portion. The first and second leaf portions pivotally connected to one another about a pivot axis that extends through one of the first leaf portion and the second leaf portion. The door leaf further comprising a lock configured, when in a locked position, to project across an interface between the two portions to thereby lock the first and second leaf portions so as to be substantially coplanar. The pivot axis is substantially parallel to and spaced from the interface.

A door system includes a door having a frame forming at least a portion of a perimeter of the door and a sleeve configured to encase at least a portion of the frame. The frame is constructed from a first material and the sleeve is constructed from a different second material. The first material may be electrically conductive and the second material may be electrically insulating. Alternatively or additionally, the first material may be susceptible to wear and tear and the sleeve may be resilient and replaceable.

A Dutch door assembly includes first and second door sections, each including a composite door member and an end cap. The composite door member includes a core member disposed between first and second end stiles, together defining a front door surface, a rear door surface, and an end surface, a front door skin secured to and substantially covering the front door surface, and a rear door skin secured to and substantially covering the rear door surface. The end cap includes a cover portion covering the end surface of the composite door member and a retention portion extending from the cover portion into engagement with the core member. The end cap of the first door section includes an abutment portion contoured to engage an abutment portion of the end cap of the second door section when the first and second door sections are in pivoted alignment.

A door include a first skin, a second skin, and a glazing unit. The first skin includes a first skin body portion, and a first flange portion extending inward from the first skin body portion. The first skin body portion has a first tip. A second skin includes a second skin body portion, and a second flange portion extending inward from the second skin body portion. The second skin body portion has a second tip. A glazing unit has an edge disposed adjacent to and between the first tip and the second tip. The first flange portion and the second flange portion provide an interlocking structure.

A door includes a door frame, first and second door skins having rectangular outer peripheries and inner openings, and a frameless glazed unit received at the openings. The door skins include exterior surfaces facing away from the door frame and opposite interior surfaces facing and secured to opposite sides of the door frame. The exterior and interior surfaces of the first and second door skins establish integral lips and grooves of the first and second door skins. Opposite sides of the frameless glazed unit directly contact and are sealed by the integral lips and sealant and/or adhesive contained in the grooves of the first and second door skins.

The present invention relates to an in-building access path installation type smoke control system. An in-building access path installation type smoke control system is openably and closably installed in an in-building access path and includes a door casing having an intake port and a discharge port, a door nozzle installed in the door casing and configured to spray water supplied from the outside, and a main door body including a negative pressure inducer configured to allow water sprayed from the door nozzle to pass therethrough, generate negative pressure on the basis of the Venturi effect while the water passes therethrough, suck gas at the periphery of the door casing through the intake port, mix the sucked gas with water, and move the gas mixed with the water downward toward the discharge port.

A door includes a door frame, first and second door skins having rectangular outer peripheries and inner openings, and a frameless glazed unit received at the openings. The door skins include exterior surfaces facing away from the door frame and opposite interior surfaces facing and secured to opposite sides of the door frame. The exterior and interior surfaces of the first and second door skins establish integral lips and grooves of the first and second door skins. Opposite sides of the frameless glazed unit directly contact and are sealed by the integral lips and sealant and/or adhesive contained in the grooves of the first and second door skins.

A security door hinge assembly is provided, comprising a door frame structure, having at least a head member, a first jamb member and a second jamb member, and at least one door leaf. The door leaf further comprises a leaf frame structure, having at least a top rail member, a bottom rail member, a hinge stile member and a lock stile member; an inner leaf panel, mounted to a first side of said leaf frame structure and extending past said hinge stile member, so as to form an inner leaf flange; an outer leaf panel, mounted to a second side of said leaf frame structure, opposite said first side, and extending past said hinge stile member, so as to form an outer leaf flange, and wherein, in use, said door leaf is operable between a first closed position and a second open position. The security door hinge assembly further comprises a hinge chamber positioned between said first jamb member and said hinge stile; a hinge-mount bracket, coupled to said first jamb member; a hinge mechanism, having at least one pivot axis and which is located within said open hinge chamber and adapted to pivotally mount said door leaf to said hinge-mount bracket, and wherein, in said first closed position, said inner leaf flange is in an exteriorly overlapping engagement with at least a portion of said hinge mount bracket, so as to prevent access to said hinge mechanism.
