TECHNICAL FIELD OF THE INVENTION
The present invention relates to a revolving door, and more particularly to a revolving door capable of increasing a selection range of materials constituting a side wall portion and securing a wide effective opening width of an entrance.
[0002]
[Prior art]
A conventional revolving door includes, as shown in FIG. 1, opposing arc-shaped side walls, openings formed opposingly by the side walls, and a plurality of door bodies radially arranged about a rotation axis. A passer-by entering the revolving door from one opening pushes the one door to rotate the plurality of doors integrally and exits from the revolving door through the other opening. . Then, while the passer is moving inside the revolving door while rotating the door, the end of one of the doors slides against the side wall to cut off communication between the space inside and outside the building, and the outside of the building. Air is prevented from directly entering the building, and this so-called wind elimination effect is a major advantage of revolving doors.
[0003]
However, the conventional revolving door has the following disadvantages.
(1) The effective opening width of the revolving door varies depending on the inner diameter and the number of doors constituting the revolving door. If the inner diameter is the same, the effective width of the opening can be increased as the number of doors increases. However, when the number of doors is increased, there is a problem that the space near the center of rotation is reduced, and in practice, it is necessary to increase the outer dimensions of the entire rotating door. (2) Since the side wall has an arc shape, usable materials are limited from a technical or economical point of view.
(3) Since the upper part of the entrance has an arc shape, a shutter for crime prevention is provided by (a) installing a horizontally opening door that moves in an arc shape, and (b) providing a shutter at a position separated from the entrance. In the case of the former, a part for storing the door body is necessary when using the revolving door, so the thickness of the door part is added to the thickness of the side wall, and the overall thickness increases. In the case of the above, there was a problem that the security performance at the revolving door portion was difficult.
[0004]
[Problems to be solved by the invention]
The present invention has been made based on a completely new idea in view of the drawbacks of the conventional revolving door, and is based on the conventional revolving door when the inner diameter of the door body is the same. It is an object of the present invention to provide a revolving door which can secure a larger effective opening width than that of the revolving door and can advantageously manufacture a revolving door or install a shutter.
[0005]
[Means for Solving the Problems]
The technical means adopted by the present invention to solve the above-mentioned problem comprises an opposing side wall and a door main body in which a plurality of doors are radially arranged, and the door main body is rotatable between the side walls. In the revolving door provided, the side wall has an opposing planar inner wall, and the door body is configured to rotate eccentrically, so that the tip end side of the door body approaches or slides on the inner wall surface. It is characterized by having done.
[0006]
By eccentrically rotating the door body, the rotation trajectory of the tip of the door body can be made to be a shape close to a square, and instead of the conventional arc-shaped wall body, a wall body facing in parallel can be adopted. It has become possible. That is, at the time of rotation of the door body, the tip of at least one or more door bodies can be brought into close or sliding contact with the inner walls of the opposing side walls, thereby ensuring the wind removal effect inherent to the revolving door. Can be.
[0007]
The door is disposed radially with respect to the axis, and the axis is configured to move along a predetermined annular moving path when the door body rotates. For example, a gear is provided at the upper end of the axis of the door main body, and meshes with an annular gear having a shape corresponding to the eccentric rotation locus of the axis of the door main body, or a guide roller is provided at the upper end of the axis, What is necessary is just to roll in the annular guide rail corresponding to the eccentric rotation locus of the axis of the main body. Further , a guide rail may be provided corresponding to the rotation trajectory of the front end of the door body, and a guide roller provided at the front end of the door body may roll in the guide rail.
[0008]
When the door body rotates eccentrically, the rotation trajectory at the tip of the door body becomes substantially rectangular, but since the rotation trajectory becomes curved at the corner, there is a fear that a gap may be formed at the end of the side wall. . It is not necessary to completely block the space inside and outside the building, so there is no problem if a certain amount of gap is formed at the end of the side wall, but in order to improve the wind removal effect, a curved end is required at the end of the wall. Preferably, a corner having an inner wall is provided, and the door is brought into close contact with or slidably in contact with the inner wall of the corner to prevent the space inside and outside the building from communicating with each other. In addition, if a bendable airtight member made of an elastic member is provided on the distal end side of the door body and the door body rotates while the airtight member approaches or slides against the inner wall of the wall, a corner portion needs to be provided. There is no. Similarly, if an airtight member is provided on the front end side of the door so as to be able to protrude and retract in the radial direction, and the airtight member is urged in the protruding direction, it is not necessary to provide a corner.
