Abstract: A multi-purpose pinless attachment system includes a first structure having oppositely facing recesses separated by a web region. Pairs of recesses form pivot bar bearing surfaces, and a transverse pivot axis passes through the web region at a midpoint between these pairs of bearing surfaces. A second structure defines an interior pivot channel between its distal tip and a proximal shank. The tip is separated from the shank by a gap to allow the web region of the first structure to pass through the gap while the interior pivot channel is brought into bearing registration with the pivot bar. The pivot channel receives the portion of the web region separating the first and second recesses. Surface portions of the pivot channel frictionally engage at least a portion of a pivot bar bearing surface while the second structure is pivoted relative to the first structure about the transverse pivot axis.

Abstract: The disclosure discloses a door device including a panel, a pivoting arm module, and a door. The pivoting arm module includes a holder and a panel-pivoting arm.

Abstract: The mechanical elevating and revolving gates consist of a support box, an overlapping monolithic plate, lever mechanisms, and hinges. The overlapping plate is raised vertically upwards by a predetermined amount (up to 1 meter), after which the said plate is turned by 90 degrees, completely opening an aperture in the support box and forming a protective cover above the gates. These two movements are carried out by a single mechanism which transforms from a crank mechanism into a four-link chain mechanism and vice versa. Such transformation is possible due to two original hinges attaching the upper part of the overlapping plate to the support box. Such gates do not require locks and bolts. Even heavy snow accumulations will not prevent the gates from opening and closing.
