A frame door with a split connection frame is provided, including a split connection frame. The split connection frame includes a first connection frame which is provided in a frame door and a second connection frame which is provided in an other frame door. The first connection frame is provided with a slide rail groove, the second frame is provided with a slide plate which engages with the slide rail groove. The slide rail groove has a C-shaped cross section so as to wrap edges of the slide plate. By using the split connection frame design, and using the sliding connection solution of slide rail groove and slide plate, on the one hand, the operation is convenient, time and labor are saved by the preset slide track during mounting process. On the other hand, the frame door is enable to be positioned in the mounting process via the preset slide track, thereby avoiding the assembly error caused by improper operation when using the existing mounting method and improving the assembly accuracy.

A panel of a sectional door includes a panel frame and a sheet of material that is coupled to the panel frame. The panel frame includes a top frame member, a bottom frame member, a first side frame member and a second side frame member. The frame members include a rear surface and a front surface, and the front surface includes a ledge. The sheet of material is coupled to the front surface such that a bottom edge of the sheet rests on the ledge and a front surface of the sheet is unobstructed by the panel frame.

A panel assembly includes a frame panel including a front surface, an upper surface, a side surface, and a rear surface and is formed as a single sheet of a metal plate, and a corner member disposed in a gap formed between the upper surface of the frame panel and the side surface of the frame panel, wherein the corner member includes: an insertion member inserted into the gap to fill the gap, and a fixing member integrally formed with the insertion member and coupled to the rear surface of the frame panel to fix the corner member to the frame panel.

Hollow core door apparatus for preventing the build up of pressure in a room having a register through which air flows into the room and the door includes an inside door skin and an outside door skin, and the door skins includes openings through which air flows and a center panel between the skins and spaced part from the skins. The center panel has an outer perimeter greater than the inner perimeter of the openings. The center panel is spaced apart from the skins, and also from the adjacent stiles and rails. A chamber is formed about the panel and between the adjacent stiles and rails and the openings in the skins. Air flow from the room is through the opening in the inside skin into the chamber, around the outer periphery of the panel, and outwardly through the opening in the outside skin in a non-linear manner.

Embodiments provide a door body which opens and closes a front part of an article body, and which has a front panel that constitutes the front of the door body, a frame that supports at least a part of the outside edge of the front panel, and a back panel that constitutes the back of the door body. According to at least one embodiment, the front panel includes a hard coat laminated sheet; the hard coat laminated sheet has a first hard coat, a second hard coat, and a transparent resin sheet layer in that order from the surface on the front side. The first hard coat is formed from a coating material which contains (A) 100 parts by mass of a polyfunctional(meth)acrylate, (B) 0.01-7 parts by mass of a water repellant and (C) 0.01-10 parts by mass of a silane coupling agent and which does not contain inorganic particles, and the second hard coat is formed from a coating material which contains (A) 100 parts by mass of the polyfunctional (meth)acrylate and (D) 50-300 parts by mass of inorganic fine particles having an average particle diameter of 1-300 nm. This door body may have a display on at least a part of the front thereof.
