[Prior Art] As a door for partitioning a space such as an air dome where there is a difference in atmospheric pressure, a general door is 40 at 20 to 6 mmAq when the door is opened.
Since the door is pressurized with a force of ~ 120 Kgf, opening and closing the door is extremely difficult and dangerous. If a device having a force that balances the pressure applied by the door and its force is attached, a mechanism for detecting the pressure and transmitting the required force to the door is required, but it is complicated and expensive. So-called balancing doors suitable for such applications, such as revolving doors, which do not narrow the effective opening width, include the following.

In the plan view of FIG. 6, the door (1) is suspended by a pair of upper and lower arms (3) extending from a suspension shaft (2) having a spring (not shown) built therein, and the door (1 ) Is provided with a guide roller (4) that engages with a guide rail (not shown) of a horizontal frame (not shown) above and below a position approximately at the center of
By rotating the arm (3) and moving the guide roller (4) according to the opening angle of the door (1), the door is opened and moved to the suspension shaft (2) side to open, and the suspension shaft (2) is installed. The door (1) is closed by the restoring force of the spring.

[Problems to be Solved by the Invention] However, in the above balancing door, since the door and the arm are located on substantially the same line when the door is fully opened, the closing force by the restoring force of the spring sufficiently acts on the door. This made it difficult to close the door smoothly. It is possible to solve this by strengthening the restoring force of the spring, but this is not preferable because the force for opening the door becomes large.

[Means for Solving the Problems] The configuration that characterizes the balancing door according to the present invention is such that the door is suspended by a pair of upper and lower arms extending from a suspension shaft having a built-in spring, and the door is substantially vertically centered. A guide roller that engages a guide rail of a horizontal frame is provided on the opposite side of the arm for applying a self-closing force to the door, and an elastic member is provided between the guide roller and the horizontal frame. Has been passed over. Further, in another embodiment, in addition to the elastic member, a speed adjusting means interlocking with the guide roller is provided, and the speed adjusting means engages with a gear fixed to a shaft that moves integrally with the guide roller, and the gear. It consists of a rack, a hydraulic device having a piston integral with the rack, and a spring inside the hydraulic device for applying a returning force to the piston.

[Operation of Means for Solving Problems] In this balancing door, even if the door is fully opened and the door and the arm are located on substantially the same line, the elastic member bridged between the guide roller and the lateral frame guides. Since the roller is stretched and pulled along with the movement of the roller, the restoring force of this elastic member effectively acts at the initial stage when the door is closed, and the restoring force of the spring built into the suspension shaft makes it possible to smoothly close the door. Further, if the speed adjusting means is provided, when the door is fully opened, it is possible to apply a torque to further close the door.

As shown in FIG. 5, when the door (1) opens, it moves to the suspension base side while rotating, so that the tension spring (6) is stretched by the amount of the rotation and a spring with a built-in suspension shaft. Is torqued. When the door (1) is fully opened, the tension spring (6) acts at a right angle to the door (1). Therefore, when the door (1) is released, the door (1) directly extends to the tension spring (6). The door (1) is then closed by the restoring force of the spring built in the suspension shaft (2) effectively acting on the door (1). The tension spring (6) exerts almost no closing force on the door as the door is closed, so that an appropriate closing speed can be obtained by adjusting the spring.

Further, the gear (8) also rotates by the amount of the rotation, so that the piston (10) is displaced through the rack (9) against the elastic force of the spring (12). Therefore, when the door is opened, the spring (1
The force of 2) causes the piston (10) to receive a returning force, so that the door (1) receives a closing torque via the rack (9) and the gear (8). As a result, the door (1) is given a self-closing force, and the rapid movement of the piston (10) is blocked by the hydraulic pressure, so that the rapid opening and closing of the door (1) is blocked. In addition, if the spring (12) is housed in the hydraulic device (11), there is an advantage that it becomes compact and a stable self-closing force can always be applied to the door.

[Effects of the Invention] As described above, according to the present invention, the door can be immediately and smoothly closed with a simple structure, and a large force is not required at the time of opening.
