Abstract

PURPOSE:To smoothly open and shut a door, by extending perpendicularly the rigid beam having having pivots 51, 52 at both sides on the upper edge of the door and by fitting one end of the extended rigid beam to a supporting arm pivoted by a connected beam to make both arms synchronize with each other. CONSTITUTION:A rigid beam U is arranged at the upper edge of a door 1 for a garage or the like and provided with pivots 51, 52 at both sides and with extension U' stretched with a right angle. Next, the extension U' are fitted at supporting arms 21, 22 pivoted in connected beams 71, 72 at the edge thereof. Next, the connected beams 71, 72 are pivoted at both sides of the door 1 and also pivoted at struts 31, 32 at the other end via pendulum levers 81, 82. Even when the door 1 is opened or closed by one of the supporting arms 21 or 22, the other synchronized supporting arm prevents the door from twisting. In this way, the door can be smoothly opened or closed.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention is applied to exterior gates for buildings, particularly garage doors.

[Conventional technology]

A rotary lift door of the type in which the lower edge of the door rises directly without creating a trajectory protruding toward the road when the door is opened or closed is disclosed in Japanese Patent Application Laid-Open No. 61-12.
It is known from No. 6287 J Utility Model Publication No. 63-91699. However, all of them had problems in opening and closing operations using a support arm that rotatably supported the door relative to the ground surface.

In other words, the movement of one support arm works, but the movement of the support arm on the opposite boundary side does not follow the same synchronization, which may cause the door to twist and become unstable, or if you hold the door, it will work, but the support arm will not follow the same movement. There are disadvantages in that it cannot be operated by holding the arm, and the rigid beam that connects the left and right support arms does not limit the height of the vehicle when the door is opened.

[Invention tries to solve! ! Title]

Technical aspects of the invention! ! The object of the present invention is to provide a direct lift rotary lift door that can be opened and closed smoothly even when the door is opened and closed by holding the edge of the door, that is, the support arm, rather than the center of the door, and the storage height of a vehicle at the opening limit is improved. .
