When the rotation speed of the biparting circular sliding door 3 is increased in an opening step which is considered to be relatively safe, to save time without changing the rotation speed of the rotary vane door 4, by using the time saved, in the dangerous region right before closing, the speed can be controlled to be slow.SELECTED DRAWING: Figure 1

Description

[Technical field]

[0001] Revolving doors were born and developed in Northern Europe, where winters are harsh, and in Japan they are often installed in large commercial facilities and skyscrapers to improve the effectiveness of air conditioning. However, in Japan, they have been used incorrectly, such as by placing a simple pole that obstructs the sensor's detection range, leading to accidents. The accident occurred when a boy jumped into the door just before it closed, causing the sensor to fail to activate properly and fail to send a stop signal for the door, and there was no preliminary means of avoidance. The area just before the door closes is considered to be a dangerous area where such accidents are likely to occur.

[0002] The cause was properly identified and the simple pole was removed as it was an obstacle to the correct detection of the sensor, but for some reason the revolving door was also removed. All the blame for human failure was placed on the silent revolving door, and a fuss was made about revolving doors being dangerous, banishing them from the public eye throughout Japan. There must be a lot of Japanese people who are only capable of narrow-minded and self-righteous thinking. The revolving door was not necessarily defective, but at the very least it should have been designed to close slowly so that the danger zone could be easily avoided.

[0003] Advantages of revolving doors that other doors do not have include "maintaining the airtightness of the building to improve the air conditioning effect of heating and cooling" and "preventing the phenomenon where the door of a room inside a building becomes difficult to open due to wind blowing in from outside". The functions of revolving doors are necessary, and in Japan, which claims to be a technology-based nation, there is a desire to develop a safer door that far surpasses revolving doors. If this cannot be achieved, Japan will remain a stain in world history as a country that simply let a six-year-old boy die in vain, a country that was unable to build Ninomiya Chuhachi's flying machine, and even more so, a country that cannot build a safe revolving door.

[0004] For the safe operation of revolving doors, it is possible to close the entrance door where people enter at a slow speed. This makes it easier to avoid danger, and the impact force is reduced due to the reduced inertia force, which shortens the stopping distance of the revolving door, and these synergistic effects greatly contribute to the safe operation of revolving doors. However, if the rotation speed of a revolving door is slowed down, the time it takes for people to pass through the entrance side to open and for people to pass through the exit side to open is lengthened, which causes problems such as not being able to let many people through, so it is difficult to close the revolving door at a slow enough speed. It would be good if there was a way to close only the entrance side of the revolving door slowly, at least in the dangerous area, without slowing down the rotation speed of the revolving door. [Background technology]

[0005] There is a revolving door that opens and closes an opening 2 in a fixed side wall 1 with a circular arc shape facing the left and right, using a revolving door 4 of a two-blade type that rotates left at the center and a revolving sliding door 6 that is integrated with the opening. There is also a door that opens and closes the opening 2 with a double-opening circular sliding door 3 in synchronization with the rotation of the revolving door 4 that rotates left at the center. In either case, the opening 2 is opened and closed with the revolving sliding door 6 or the double-opening circular sliding door 3 at the same rotation speed as the revolving door 4 that rotates at the center. With these doors, there is a possibility that someone may jump in just before the door closes, and the area immediately before the door closes is considered to be a dangerous area. If this dangerous area immediately before closing can be closed slowly, it becomes easier to take action to avoid danger, and the stopping distance is shortened due to the reduced inertia force, which creates various synergistic effects and greatly contributes to safe driving.

[0006] The rotating blade door 4 that rotates left in the center of Figure 1 is not involved in the entrance and exit of people, and the non-rotating double-leaf circular sliding door 3 is used for the entrance and exit of people, so it should be called a double-leaf circular sliding door 3 rather than a rotating door. Since it opens and closes from both the left and right sides, the opening and closing time is halved and shortened. In the integrated structure of the rotating sliding door 6 and the rotating blade door in Figure 5, the rotating sliding door 6 rotates at the same speed as the rotating blade door 4. In order to rotate the rotating sliding door 6 and the rotating blade door 4 at different speeds, the rotating sliding door 6 and the rotating blade door 4 must be structured separately. If they are structured separately and each door has its own driving power, they can be operated at different speeds by control, and it is also possible to operate at a low speed only in the dangerous area of ​​the closing process. It is the same as driving a car, but the basis of safe driving is to drive slowly at a low speed in areas that are considered dangerous, such as where someone may jump out.

[0007] Patent No. 4385187 Summary of the Invention

[0008] As an example, Figure 1 shows a circular sliding door with a double-leaf revolving door function in a fully open state, moving into the closing process. On the left and right, there are fixed side walls 1 in the shape of an arc at an angle of about 90 degrees from the center, and the opening 2 is equipped with double-leaf circular sliding doors 3 at an angle of about 45 degrees from the center that slide open from the left and right to open and close. In the center, there is a two-leaf type rotating blade door 4 that extends to the left and right and rotates left. If the rotating blade door 4 that rotates left in the center and the double-leaf circular sliding doors 3 on the left and right are each provided with a driving power, the double-leaf circular sliding doors 3 on the left and right can be opened and closed at a rotation speed different from that of the rotating blade door 4 by control.

[0009] In addition, the rotary blade door 4 requires a stopping distance in the event of an emergency stop due to inertia force, and this is taken into consideration in the control so that it does not go ahead of the circular sliding door 3. The rotation of the rotary blade door 4 and the opening and closing of the double-opening circular sliding door 3 are synchronized. In the closing process, the stopping distance of the rotary blade door 4 is taken into consideration, and if the rotary blade door 4 remains on the left-hand circular sliding door 3 excluding the stopping distance from the tip and does not come off, it is within the range of synchronization. When closing, the rotary blade door 4 transfers from the left side to the right-hand circular sliding door 3, and in the opening process, it is within the range of synchronization if the rotary blade door 4 remains on the right-hand circular sliding door 3. The control is performed so that the rotary blade door 4 does not go ahead of the left-hand circular sliding door 3 even in the event of an emergency stop. The control closes the double-opening circular sliding door 3 at a slow rotation speed of about half that of the rotary blade door 4 in the danger area of ​​the closing process.

[0010] From the state shown in Figure 1, the left circular sliding door 3 closes from both the left and right directions while maintaining airtightness in sync with the rotation of the rotary blade door 4 rotating left, and closes at the front. Even in the event of an emergency stop during this closing process, the left circular sliding door 3 closes ahead of the rotary blade door 4 by the stopping distance so that the rotary blade door 4 does not move forward. From the state shown in Figure 1 until it is fully closed at the front, the tip of the left circular sliding door 3 needs to rotate about 45 degrees and the rotary blade door 4 needs to rotate about 90 degrees, so the left circular sliding door 3 can close at a slower angular speed, about half that of the rotary blade door 4.

[0011] In the revolving door of Figure 5, it is better for the rotation speed of the revolving blade door 4 to be slower for safe operation, but the rotation speed is an important factor for letting many people through, and it is difficult to make it sufficiently slow. Only the rotation speed of the revolving slide door 6 is controlled to be slower in the danger zone of the closing process. In the double-opening circular sliding door 3, the rotation speed of the revolving blade door 4 is not changed in the danger zone, and only the rotation speed of the circular sliding door 3 is controlled to be slower. The inertia force of the circular sliding door 3 is reduced, shortening the stopping distance and reducing the impact force, which have a synergistic effect that greatly contributes to safe operation. [Problem to be solved by the invention]

[0012] A double-wing circular sliding door 3 that slides from the left and right to open and close an opening 2 is provided on fixed side walls 1 in the shape of a circular arc facing the left and right, and opens and closes the opening 2 while maintaining airtightness by synchronizing with the rotation of a rotary blade door 4 that rotates left in the center. As a basis for safe operation, this circular sliding door 3 should be closed slowly in the danger zone of the closing process. It is desirable to slow down the closing speed of the circular sliding door 3 to about half the rotation speed of the rotary blade door 4. The closing speed is an important factor in avoiding accidents such as getting caught during opening and closing, so it is necessary to keep it as slow as possible. However, the rotation speed of the rotary blade door 4 cannot be slowed down because it would cause problems such as lengthening the time it takes to pass through the door.

[0013] From the state shown in Fig. 1, the left double-leaf circular sliding door 3 starts its closing stroke ahead of the rotary blade door 4 by a distance equal to or greater than the stopping distance, and then stops when it reaches the front first. The rotary blade door 4 reaches the front later, and then moves onto the right double-leaf circular sliding door 3 before moving on to the next opening stroke. In the opening stroke, the circular sliding door 3 rotates at the same speed as the rotary blade door 4. In the fully open state shown in Fig. 1, the circular sliding door 3 is stopped, and the rotary blade door 4 rotates to move onto the next closing stroke shown in Fig. 1. They are synchronized, but in the closing stroke, the rotary blade door 4 only needs to be on top of the left circular sliding door 3, and in the opening stroke, if it is on top of the right circular sliding door 3 and does not come off, it is within the range of synchronization. The rotary blade door 4 and the double-leaf circular sliding door 3 are operated at different rotation speeds, and at least the dangerous area of ​​the closing stroke of the double-leaf circular sliding door 3 is operated at a low speed.

[0014] Even in the case of a revolving door that opens and closes the opening 2 in the fixed side wall 1 shown in Figure 5 by using a revolving slide door 6 that rotates counterclockwise, if the rotating blade door 4 and the revolving slide door 6 structures are separated and each is given its own driving power, they can be opened and closed at different rotation speeds by control, and only the danger area of ​​the closing stroke is closed at a slow speed by the revolving slide door 6.

[0015] The power to drive the rotary blade door 4 and the double-opening circular sliding door 3, or the rotary blade door 4 and the rotary slide door 6, is distributed, so that although the number of doors increases, only a small power is required, and control becomes easier.

[0016] Although it is prohibited to jump into the double-leaf circular sliding doors 3 just as they are about to close, there are steps you can take. Immediately stop the rotation of the rotary blade doors 4 and open only the right-side circular sliding door 3. As the rotary blade doors 4 are about to close, collisions are unlikely to occur because they are parallel to the direction of travel of people. After a person has entered or left, the right-side circular sliding door 3 is closed so that operation can be resumed. If the double-leaf circular sliding doors 3 are set to a slow speed, it becomes easier to take action to avoid danger, and a synergistic effect is achieved in which the stopping distance is shortened due to the reduced inertia force and the impact force is reduced. [Means for solving the problem]

[0017] Fixed side walls 1 in the shape of an arc at an angle of about 90 degrees from the center face each other on the left and right, and on the left and right of the opening 2 are double-leaf circular sliding doors 3 at an angle of about 45 degrees from the center that slide left and right to open and close the opening 2, which opens and closes while maintaining airtightness and synchronizing with the rotation of a rotary blade door 4 that rotates left in the center. If the rotary blade door 4 and the double-leaf circular sliding door 3 are each provided with a driving force, the rotary blade door 4 and the double-leaf circular sliding door 3 can be operated at different speeds by control. By controlling the rotary blade door 4 without changing the rotation speed, it is possible to slow down only the speed at which the double-leaf circular sliding door 3 closes in the danger zone of the closing process within a range where synchronization can be maintained.

[0018] Since the opening 2 is opened and closed from both sides, the opening and closing time is halved and it can be done quickly, but for safe operation, it is better to do it slowly. From the state of Figure 1, the tip of the left circular sliding door 3 is caught, so the double-opening circular sliding door 3 closes at about half the angular speed of the rotary blade door 4, but to close it at the front, it needs to rotate about 45 degrees, and the rotary blade door 4 needs to rotate about 90 degrees, so it closes at about half the angular speed of the rotary blade door 4 considering the stopping distance of the rotary blade door 4. The double-opening circular sliding door 3 is closed at the front first, and the rotary blade door 4 reaches the front with a delay of the stopping distance, and then it moves onto the right circular sliding door 3 and moves to the next opening stroke. The opening stroke ends in the state of Figure 1 and moves to the next closing stroke. During the half rotation of the rotary blade door 4, the double-opening circular sliding door 3 performs the closing stroke, the stopping stroke, and the opening stroke.

[0019] Time is saved by speeding up the opening speed of the double opening circular sliding door 3 in a relatively safe area such as the opening stroke without slowing down the rotation speed of the rotary blade door 4, and the saved time is used to slowly close the double opening circular sliding door 3 in the dangerous area of ​​the closing stroke. By slowly closing the double opening circular sliding door 3 related to the entrance and exit of people, the inertial force is reduced, the stopping distance is shortened, and various synergistic effects are generated to obtain a great safety driving effect. Effect of the Invention

[0020] To allow people to safely enter and exit revolving doors, it is essential to keep the speed slow, but slowing down the rotation speed can have disadvantages such as not being able to let many people through. By not slowing down the rotation speed and only slowly closing the circular sliding door 3 just before closing in the closing stroke, which is the dangerous area, it becomes easier to take action to avoid danger, the stopping distance becomes shorter due to the reduced inertia force, and the impact force is also reduced. The synergistic effects of all these factors can greatly contribute to safe driving. The same is true for revolving doors that open and close the opening 2 with a revolving sliding door 6. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS EXAMPLES

[0021] As shown in FIG. 1, the double-opening circular sliding door 3 of the present invention opens and closes an opening 2 in an arc-shaped fixed side wall 1 facing the left and right by sliding it from the left and right. The opening and closing operation is performed while maintaining synchronization with the rotation of the rotary blade door 4 that rotates left at the center. Each door is provided with a driving power, and the rotary blade door 4 and the double-opening circular sliding door 3 can be rotated at different speeds while maintaining synchronization by controlling them. The speed at which the double-opening circular sliding door 3 closes the danger area of ​​the closing process can be slowed down to about half the rotation speed of the rotary blade door 4. The synchronization is within the range of synchronization when the rotary blade door 4 is on top of the left circular sliding door 3 excluding the stopping distance from the tip during the closing process and does not come off, and when the rotary blade door 4 does not come off from the right circular sliding door 3 during the opening process, it is within the range of synchronization.

[0022] FIG. 1 shows the fully open state of the double-opening circular sliding door 3 of the present invention, which will now move into the closing stroke. The rotating rotary blade door 4 and the double-opening circular sliding door 3 generate inertial forces, so a stopping distance is required to stop them. To close at the front, the rotary blade door 4 must be rotated about 90 degrees, and the tip of the double-opening circular sliding door 3 must be rotated about 45 degrees from the left and right, but the rotary blade door 4 must reach the front and stop by the stopping distance. The rotary blade door 4 reaches the front with a delay, and when it transfers to the circular sliding door 3 on the right side, it moves into the opening stroke. In the opening stroke, the circular sliding door 3 can be rotated at the same speed as the rotary blade door 4. When the state shown in FIG. 1 is reached, the opening stroke is completed and it moves into the next closing stroke.

[0023] When there are few people entering and exiting the facility, the facility can be automatically or manually switched to standby mode in the state shown in Fig. 1. It is also possible to switch to standby mode with the circular sliding door 3 closed.

[0024] EXAMPLES

[0025] In the case of the revolving door shown in FIG. 5, which opens and closes the opening 2 in the fixed side wall 1 with the revolving sliding door 6, if the revolving sliding door 6 and the revolving blade door 4 are separated and each is provided with a driving force, the revolving blade door 4 and the revolving sliding door 6 can be rotated at different rotation speeds by control. The revolving sliding door 6 can be closed at a low speed of about half the rotation speed of the revolving blade door 4 in the danger zone of the closing stroke. The synchronization is within the range of synchronization if the revolving blade door 4 is placed on the revolving sliding door 6 excluding the stopping distance from the tip of the revolving sliding door 6 and does not come off. The revolving sliding door 6 can be closed at about half the rotation speed of the revolving blade door 4 in the danger zone of the closing stroke, and the revolving sliding door 6 can also be opened at a rotation speed faster than the revolving blade door 4 in the opening stroke. By slowing down the closing speed of the revolving sliding door 6, it becomes easier to take risk avoidance actions, and the inertial force is reduced, so the stopping distance is shortened and the impact force is also reduced, and the synergistic effects of various factors contribute to safe driving.

[0026] [Industrial Applicability]

[0027] Industrial machines should be operated at a slow speed unless it causes problems such as a long tact time and poor efficiency, as this makes it easier to take action to avoid danger and contributes to safe operation. Doors are also widely used in industry, and high-quality ones are required to improve cooling and heating efficiency and improve the environment. [Brief description of the drawings]
