To provide regulating parts and fixtures that allow for easy removal of shoji screens. [Solution] The joinery 1 comprises a frame 2 provided in the opening 101 of the building 100, a sliding door 31 provided on the inner circumference of the frame 2, without an opening / closing arm, with its lower end supported by the frame 2 and its upper end being able to tilt inward toward the interior, and a frame provided extending further inward toward the interior than the frame 2. The restricting component 50 is provided on the frame 2 and restricts the opening of the sliding door 31 by contacting at least one of the interior side surface of the sliding door 31 or the bottom surface of the sliding door 31 when the sliding door 31 is opened.

The present invention relates to an explosion-proof leaf intended to be fitted to a door (B), the explosion-proof leaf (B) extending in thickness along an axis, referred to as the axis (X) of the explosion-proof leaf (B), between two opposite outer faces (BO, B1) of the leaf (B), a front outer face (BO) liable to be exposed to a possible explosion originating from a source located on, or close to, the front outer face (BO), and a rear outer face (B1), the explosion-proof leaf further comprising a frame element (B2) able and intended to be mounted, more particularly pivotably, on the frame (D) of a door (P) so as to allow the explosion-proof leaf (B) to move in the door (P). It is characterized in that the explosion-proof leaf comprises at least one explosion-proof module (M1, M2) arranged fixedly between the front outer face (BO) and the frame element (B2) and comprising two explosion-proof panels arranged one behind the other and in contact with one another, each extending perpendicularly to the axis (X) of the leaf (B), namely a front explosion-proof panel (1) and an apertured rear explosion-proof panel (2) configured and interposed between the front explosion-proof panel (1) and the frame element (B2) in order to keep the front explosion-proof panel (1) and the frame element (B2) at a distance from one another, while being able to disperse and absorb at least a portion of the explosion energy not dispersed and / or not absorbed by the front explosion-proof panel (1). The present invention further relates to an explosion-proof door comprising at least one such explosion-proof leaf.

This utility model relates to the field of lifting door technology and discloses an electric lifting door for a small-space storage warehouse. It includes a lifting door frame, a lifting door panel slidably mounted on the lifting door frame, an extension groove on the rear side of the lifting door panel, a through-hole in the extension groove, an opening / closing plate installed in the extension groove, and a positioning component installed on one side of the opening / closing plate. The opening / closing plate is used to close and open the through-hole, and the positioning component is used to fix the position of the opening / closing plate when the through-hole is closed. This utility model overcomes the shortcomings of the prior art. By opening a through-hole on the lifting door panel, when retrieving a small quantity of material, it is not necessary to fully open the lifting door panel. The material can be retrieved by opening the opening / closing plate at the through-hole, reducing the area of ​​the storage space in contact with the external environment. Simultaneously, the horizontally arranged opening / closing plate can support the material during retrieval, providing convenience for workers.
