Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to external gates for buildings, particularly garage doors.

・Conventional technology There are proposals such as Japanese Patent Publication No. 57-53507 and Japanese Patent Application No. 59-172030 filed by applicant □ regarding the rotating elevator door, but the present invention is based on the basis of these proposals. 1. Propose the new configuration identified.゛Problems to be solved by the invention Technical aspects of the invention! ! The - in the title is suitable for the pivot point of the support arm.
The goal is to simplify the peripheral configuration. The benefits associated with simplification will be described in the "Effects" section below.The second technical challenge is to make the biasing force load relatively light.

・Means and Examples for Solving the Problems The structure of an embodiment of the roof-mounted rotating elevator door according to the present invention is described with reference to a drawing. The straight line that intersects is set as the axis of rotation X, and the two shaft fulcrums 41 and 42 arranged on the axis Second pillars 31 and 32,
One end 21a, 22a is pivotally supported by the two shaft supports 41, 42, and the height of the shaft support points 41, 42 is rotatable over a range of approximately 906 degrees within a plane intersecting the axis X. Two support arms 21 and 22 of approximately equal length, a decorative board 1 installed across the open ends 21b and 22b of the two support arms 21 and 22, and the Ill and the above two support arms. 21, 22, etc., which counteracts the gravitational moment exhibited by the pivoting parts relative to the axis A groove ring 51 (52) having a support axis Y parallel to the axis X is provided to support the support arm 2 when descending.
At least -21 (22) of 1.22 and 1-recorded groove ring fi
A school matter 61 (6, 2) is stretched between the school matter 61 (6, 2) and the tip 61a ( 62a) is indirectly biased by one force using the biasing spring F. Note that the roofed garage may have one leg (inverted-shaped) or both legs (inverted U-shaped), and may be a standing type constructed with a concrete support wall. Of course pillar 31
・32 is included in a part of the supporting wall. Indirect biasing of the biasing spring F means that the distal end 61a of the academic matter 61 is engaged with the moving groove ring 51, and the groove ring 51 is engaged with the groove ring 51 using a spiral spring or a spring arranged coaxially with the support shaft Y. This means that the tip 61a of the academic matter 61 is indirectly biased to rotate. Naturally, the groove ring 51 may be formed integrally with the groove ring 52 on the opposite side into a long cylindrical shape. What is direct bias?
Regardless of the transfer of Mizowa 51 (52), Academic Affairs 61
This refers to directly urging the tip 61a (62a) of (62). Gakuji 61 (62) can also be chained, and of course groove ring 5
1 (52) may be a sprocket. Support arm 21・
A stopper for limiting the rotational distance of 22 with respect to the axis X to a range of approximately 90° is not shown for the sake of clarity. Furthermore, the mini-digits 2 and 1 used in this specification indicate the difference between the left and right support arm systems, and some of them are not shown in the drawings, but these are different from those of other systems. appear identical.

Function Since the present invention has the above structure, academic affairs 61 (6
2) and the support arm 21 (22) approaches the open end 21b (22b) of the support arm 21 (22), the biasing force of the biasing spring F can be significantly reduced. However, since the amount of displacement increases, a spring with a sufficiently large amount of deflection must be selected. Also, if the spring constant of the biasing spring F is selected in advance so that the residual load of the biasing spring F is minimal when the support arms 21 and 22 are vertical (when the door is open). Even if the rotational moment due to gravity of #Il just before the door is opened (the moment in the closing direction) is small, the moment in the return direction/(door opening direction) of the biasing spring F remains above it than necessary. This eliminates the inconvenience of the support arms 21, 22, etc. colliding with the stopper. On the other hand, in a configuration using a weight biasing system, such as the one cited in Tokugansho (see Figure 2 @), the Gakuji 61 (6, 2) and the support arm 21,
Especially when the engagement point with 22 is close to the pivot points 41 and 42,
As the door approaches the open ends 21b and 22b, the impact of the door opening and the collision of time becomes stronger. This is due to the natural law that the tension of the workpiece caused by the weight bias remains unchanged throughout the entire process of opening and closing the door.

, Effects of the Invention According to the present invention, the academic affairs 61 (, 62) and the support arm 21 (
22) can be easily moved away from the shaft fulcrums 41 and 42, and can be kept away from the passage through the entire door opening/closing process. -42 only, so
The vicinity of the shaft support points 41 and 42 can be significantly simplified. As a result, compared to the intention of mechanically operating the opening and closing of the prisoner by disposing a motor or the like near the shaft fulcrum, there are fewer obstacles in the vicinity, which is convenient. ′
