The present disclosure provides a commercial door chassis that utilizes screw splines instead of prior art shear blocks to connect the chassis rails to the chassis stiles. Each of the door stiles has a small opening near each end on the exterior face of the stile in which the screw splines may be inserted through the stile to couple with an end portion of the adjoining rail, thereby providing a tension joint. A joining plate may be added to the chassis for increased support fastening between the rail and the stile, and may be inserted into the inner portion of the stile as the screws are fastened. In addition, the exterior face of the stile comprises a groove down the length of the exterior face of the stile in which a plurality of different astragals may be positioned to provide an exterior shape of the door chassis as desired.

The present application discloses a climate chamber comprising at least one housing comprising a door, with an interior volume which is closable with the at least one door, wherein the at least one door comprises an inner wall and an outer wall, wherein the inner wall is formed of a unitary and bendable base body which comprises a polygonal wall section enclosed by side regions, wherein from each of the side regions projects a tongue with its free end, wherein the tongue in a first edge is canted from the wall section into a first section to form a tray and wherein the free end of the tongue is canted back by a second edge into a second section in order to form a sealing seat into which a sealing can be set.

A security screen assembly for a door or window is disclosed herein. The assembly includes a frame with a reinforced lip, a mesh, a plastic insulator to insulate the frame from the mesh and a retaining wedge to hold the mesh in the frame. The characterising feature is that the mesh has cut and punched indentations which abut against the reinforced lip within the plastic insulator to prevent the mesh being withdrawn from the frame once the retaining wedge is in place.

An assembled door frame is provided, including multiple of side frames spliced together, where every adjacent two of the side frames spliced at right angle are connected via a corner connector assembly. The corner connector assembly is arranged inside the every adjacent two of the side frames spliced at right angle. The corner connector assembly includes a corner connector and fixing bolts, and one of the every adjacent two of side frames spliced at right angle is fixed on the corner connector by the fixing bolts. In the embodiments, the side frames are spliced directly together through the respective corner connector assemblies each including the corner connector and the fixing bolts. On one hand, the corner connector and the fixing bolts are each disposed within the corresponding side frame, such that the original external structure of the side frames will not be changed after the side frames are spliced together, thereby reducing assembly errors of the door frame caused by using the connecting structure. On the other hand, the direct splicing of the side frames is achieved merely by two types of members that are the corner connector and the fixing bolts. So compared with the prior art, a welding process of the side frames is not required, the structure thereof is simple, and the mounting thereof is convenient.

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 sliding door system and method is used in an enclosure that defines an inner area shielded against a High-Altitude Electromagnetic Pulse (“HEMP”). The HEMP shielded sliding door system includes an RF shielding door frame, an RF shielding door leaf mounted within an mechanical door leaf frame, a mechanical insertion and retraction assembly attached to both the mechanical door leaf frame and RF shielding door leaf and that operates to extend and retract the RF shielding door leaf into and out of the RF shielding door frame, a drive tube assembly operable to interact with and open and close mechanical door leaf frame (along with RF shielding door leaf) in a sliding motion, and a control assembly, including motor and an air regulator assembly. HEMP shielding air seals are activated when the RF shielding door leaf is inserted into the RF shielding door frame.

A metal door includes a pair of sheet metal door panels. Each of the door panels includes a central body portion with top, bottom and opposing side edges. The doors include an integral flange along each side edge of each panel. The integral flange extends generally perpendicular to the central body portion. An integral inturned lip can be located along each flange and extend substantially parallel to the central body portion. The door panels are positioned such that the central body portions are in an opposing spaced apart relation to one another with the flanges adjacent to and aligned with one another. The inturned lips are positioned in contacting face-to-face relation. The metal door also includes an elongate connector overlying and clamping together each face-to-face pair of inturned lips to maintain the door panels in assembled relation.

A door (10) comprising a door member having a rectangular frame (22) on which components forming the door member are assembled. The frame includes top, side and a bottom frame member (24, 26a, 26b, 28). The frame is sized and shaped to fit within an opening (P) in a sidewall (S) of a portable building (B). A foam panel (16) fits in the frame. Door panels (12, 14) are affixed to the outsides of the foam panel using an adhesive material. The result is a laminated door that can be lowered and raised for moving people and objects into and out of the building.

A method of making a door involves providing a first door facing including a first raised region and a first panel recessed from the first raised region by a first dimension, and securing a first core insert having a thickness equal to the first dimension to the first raised region. A second door facing including a second raised region and a second panel recessed from the second raised region by a second dimension is provided. A second core insert having a thickness equal to the second dimension is secured to the second raised region. A central core component is secured to the first panel and the first core insert after the first core insert has been secured to the first raised region. The second panel and the second core insert are secured to the central core component after the second core insert has been secured to the second raised region.

A metal door and the method of making a metal door having powder coated, front and back skins, powder coated hinge and lock channels powder coated top and bottom channel and a core positioned within the door assembly.
