Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to an exterior gate such as a building door, particularly a garage door.

The technology related to multiple parallel rotary lift doors is SAIKAI Sho 61-20764.
No. 63-86292, etc. However, with the above techniques, there is a drawback in that the material efficiency is poor in that the structure of the structural member has a multi-layer structure (6 layers are 4 layers) when viewed in the rotational axis direction of the rotating part such as the door and the support arm. there were.

[Problems to be solved by the device]

The technical problem of the present invention is to simplify the structure of the structural member as viewed in the axial direction of the rotation of the rotating portion, as much as possible, with respect to the columns of the multiple parallel rotary lift doors.

[Means and Examples for Solving the Problems]

A configuration of an embodiment of a pillar of a multiple parallel rotary lift door according to the present invention will be described with reference to the drawings. In the vicinity of two side edges of the door 1,
Each of the support arms 21 in the direction intersecting the main surface of the door 1
One end of 22 is attached, and the other ends of the support arms 21 and 22 are respectively attached to two axis fulcrums 41 and 42 arranged on one axis X axis orthogonal to the lateral boundary surface. Rotation so that the door 1 is pivotally supported and the door 1 is lowered to close the door when the main surface is vertical, while the door 1 is raised to open when the door is horizontal. In the elevating door, it is possible to mount the support arms 21 and 22 on the shaft fulcrums 41 and 42, which are supported on the surface of the ground, from both sides of the support columns 31 and 32. In addition, a symmetric structure is formed in a plane that passes through the axis of the columns 31 and 32 and is parallel to the lateral boundary surface, and the nested bearing plate T is attached to the columns 31 and 32 from above the columns 31 and 32 along the plane of symmetry. A shaft hole V, which is conceivably sunk concentrically from both sides of the bearing plate T in the telescopic bearing plate T, is fitted to the shaft X in the same manner as the shaft X. Is a and the shaft fulcrum
It is configured to be involved as a bearing for 41 ・ 42. It should be noted that G is an urging member (for example, a gas spring) for reducing the gravity of the rotating portion K such as the door 1 and the supporting arm 21, and P is designed to move together with the rotating portion K at the shaft fulcrums 41 and 42. The arm shafts and R are projections which are designed to rotate together with the arm shaft P, and hence the support arms 21 and 21, and a stopper for limiting the rotation stroke of the rotating portion K is separately provided. Not shown for clarity.
In addition, the second digit of the reference numeral used in this specification
Reference numeral 1 indicates the left and right sides of the support arm system, and some of them are not shown, but they appear the same as those of the other systems.

[Action]

Since the present invention has the above configuration, when assembling the columns 31 and 32, first, from the left and right sides of the columns 31 and 32, the axis X,
Therefore, the arm shaft P is fitted into the hole formed corresponding to the shaft fulcrum 41/42, and the piercing piece R is attached to the arm shaft P, so that the inner end portion of the rear arm shaft P is located at the center of the columns 31/32. Through a shaft hole V recessed in a telescopic bearing plate T vertically fitted to
The arm shaft P prevents the arm shaft P from slipping out in the direction of the axis X, while suspending a biasing member G such as a gas spring between the tip of the piercing piece R and the lower part of the support column 31/32 (the shaft hole V is penetrated). It may be a hole.) Since the support arms 21 and 22 can be attached to both right and left sides of the columns 31 and 32 thus formed, they are suitable as columns for multiple parallel rotary lift doors (a rotary lift door for one unit). When columns are installed side by side, columns 31 and 32 are 1 each on the boundary surface.
Two of them will be planted in total, but one pillar can be planted in the present invention, which is advantageous for construction of multiple parallel parking lots. ).

The only drawback is that the outermost strut has a dead space of 1/2 in plan view, but it is not so important for practical use, and a strut volume of 1/2 dead space is embedded in the side wall. It is possible to avoid this by, for example, cutting the halves of the columns vertically. In the case of normal use, the openings as the shaft fulcrums 41 and 42 on the outermost surface of the outermost column may be watertight with a blind plate or the like.

[Effect of device]

According to the present invention, since the structure of the support shafts 31 and 32 viewed from the rotation axis of the rotary unit of the rotary lift door, that is, the axis X direction is composed of three layers of the outer periphery of the support shafts 31 and 32 and the bearing plate, It can be said that the structure is simpler and the material efficiency is better than before.
