Description

[Detailed description of the invention]

The present invention relates to a turnstile used for controlling the passage of a large number of customers one by one at entrances and exits of stations, entertainment venues, stadiums, etc., and regulating or restricting the direction of passage. In general, a turnstile has a plurality of arms protruding from the end of a rotating shaft at regular intervals along a conical surface, and the rotating shaft is tilted at a certain angle so that the arms become approximately horizontal one after another. Normally, the rotation of the rotating shaft is locked, and the rotating shaft is unlocked in response to a gate opening signal, and the arm is manually pushed at a predetermined angle by the customer. The rotating shaft is rotated when the next arm reaches a horizontal position to prevent the next customer from passing. is configured to relock. and,
If the customer stops passing, the arm returns to the closed passage position, and after the customer has passed, the rotation is performed in order to advance the next arm to the closed passage position quickly and with enough force to prevent unauthorized passage. Means are used to bias the shaft to a force that holds it in place. In conventional turnstiles, mechanical energy from a combination of a coil spring and a cam is used to maintain the rotating shaft in a fixed position. Therefore,
The structure has contact parts, which wear out and have a limited lifespan. In addition, when a combination structure of coil springs and cams is used for a bidirectional turnstile, that is, a turnstile that can be used for passage control in both the entrance and exit directions, customers can pass through the gate both in the entrance and exit directions. It is difficult to design a cam shape that allows the arm to rotate quickly when entering the gate passageway, and slowly rotates the arm when exiting from the gate passage. The disadvantage of using such a cam shape was that it prevented passengers from passing smoothly. An object of the present invention is to provide a turnstile that uses magnetic energy as a force for holding the rotating shaft in a fixed position, so that the desired action can be obtained without contact, and the life of the turntile is extended without wear. do. The turnstile according to the present invention has a donut-shaped rotor fixed at its center on a rotating shaft having a plurality of arms fixed at a fixed angle, and a similar donut-shaped rotor attached adjacent to the rotor. Alternatively, a disk-shaped casing is provided parallel to the rotor, and the centers thereof coincide with each other, and magnets are provided on the rotor and stator at equal intervals in the circumferential direction, and the magnets of the rotor are all of the same polarity on the stator side. Toward this end, all the magnets on the stator side are arranged with the polarity of the magnets on the rotor facing the rotor side. If such a magnet arrangement structure is used, for example, in a turnstile with three arms aligned, when an ordinary customer stops passing and retreats when the arm in the closed position rotates up to 60 degrees, Or, when a slender customer rotates his arm up to 90 degrees and then passes without pushing his arm further, the rotor magnets and stator magnets are alternately spaced at equal intervals of 60 degrees.
There is a risk that a dead center will occur, the rotor and thus the rotating shaft will not rotate back to the home position in either direction, and that none of the arms will perform a passage blocking function. Therefore, the present invention provides a turnstile that uses magnetic energy as a force for holding the rotating shaft in a fixed position, and that prevents the rotating shaft from returning to the fixed position due to a dead center caused by each set of attracting magnets. The second purpose is to provide Next, embodiments of the present invention will be described based on the drawings. FIG. 1 is a front view of an example of a gate with a turnstile attached thereto, and FIG. 2 is a side view of the same. In Figures 1 and 2, the turnstile indicated generally at 1 is attached to a gatebox 2, and a similar gatebox or shelf or It is used to control the passage of people through the gate passageway 3 formed between the wall and the wall. The gate box 2 has a recess 4 in the center of the front.
By attaching the base of the turnstile to the upper inclined surface of the recess so that the rotation axis described later has an angle of 45° with respect to the vertical line, the arms 5 ₂ and 5 ₃ in the open position and the base of the turnstile are connected to the gate. The front of the box does not protrude into the gate passage 3 as much as possible so as not to obstruct people's passage through the gate passage. The turnstile 1 has a mounting plate 6 for mounting it on the gate box 2. Mounting plate 6
is brought into contact with the upper angular surface 4a of the recess 4 of the gate box from the outside, and is fixed to the gate box by bolts and nuts or other fixing means. The gate box is provided with a hole on the back side of the mounting plate 6 which is smaller than the mounting plate. A bearing 8 is inserted into a hole 7 provided in the center of the mounting plate, a bolt 10 is passed through a flange 9 formed at one end of the bearing, and the bolt 10 is screwed into the mounting plate 6, so that the bearing 8 is attached to the mounting plate. It is fixed. A rotary shaft 11 that protrudes both inwardly and outwardly of the mounting plate 6 passes through the bearing 8 and is rotatably supported. A hub 12 is fixed to one end of the rotating shaft 11 on the outside from the mounting plate 6 with a bolt 13.
The hub has three arms 5 ₁ , 5 ₂ extending along a conical surface at an angle of 45° to the axis of the rotating shaft 1 and spaced apart from each other by 120° in the circumferential direction. 5 ₃ is provided. Each arm is fixed to a socket 14 formed in the hub 12 by press fitting or screwing 15. At the other end of the rotating shaft 11 located inside from the mounting plate 6, there is a donut-shaped rotor 16 which is a component of the rotating shaft fixed position holding means described later.
is fitted in a hole 17 provided at its center, and fixed with a key 18, a bolt 19 and a nut 20. The rotor 16 has holes near its circumferential end at positions spaced apart by 120 degrees in the circumferential direction concentrically with the rotor, and permanent magnets 21 ₁ , 21 ₂ , 2 are placed in each hole.
1 ₃ are fitted, and magnetically non-permeable disks 22 and 23 are joined to the inner and outer surfaces of the rotor. The lines of magnetic force of each magnet 21 ₁ , 21 ₂ , 21 ₃ are
The flow is parallel to the axis of the magnet, and the magnets are arranged so that the same magnetic poles of each magnet face the same direction. One end of a support member 24 is fixed to the mounting plate 6, and extends from the outside in the diametrical direction of the rotor 16 to the opposite side of the mounting plate with respect to the rotor. A ring-shaped holding member 25 having a slightly larger diameter is fixed with its center aligned with the center of the rotating shaft 11,
A stator 26 is fixed inside the holding member 25. The stator 26 has almost the same structure as the rotor 16, and three permanent magnets are arranged so that the lines of magnetic force flow parallel to the rotating shaft 11, with an interval of 120 degrees in the circumferential direction. However, the permanent magnets of the stator are arranged such that their polarity, which is different from that of the magnets of the rotor, faces toward the rotor. Components of the stator corresponding to each component of the rotor are indicated by adding an e to the former code. In this invention, as described above, the rotating shaft fixed position holding means are fixed on the rotating shaft 11 at the center, and are arranged at intervals of 120° on the circumference with the same polarity facing the same direction. a rotor 16 having permanent magnets, which are non-rotatably disposed close to the rotor in a parallel state, and which are arranged at intervals of 120 degrees on the circumference and have magnetic poles different from the permanent magnets of the rotor in the rotor direction. The stator 26 has a permanent magnet arranged toward the stator 26. As shown in FIGS. 1 and 2, when any one of the arms ₅₁ is in a horizontal state and closes the gate passage 3, each magnet of the rotor 16 is connected to the stator 26. The rotating shaft 11 is held in a fixed position by approaching each magnet and attracting each other. When attempting to pass through the gate passageway 3, for example in the left _direction in FIG.
When rotated through 120 _° to the arm ₅₁ position shown in FIG. ii) rotates to a horizontal position and prevents the next customer from passing. In this process, arm 5 ₁
The rotating shaft 1 is pushed by a force greater than the attractive force of the three sets of magnets of the rotor 16 and stator 26.
1 begins to rotate, and each set of magnets separates. When one customer passes and the next arm ₅₃ is in a horizontal state, that is, the rotation angle of the rotating shaft 11 is 120 degrees, the rotor 16
The different pairs of magnets in the stator 26 and the stator 26 are again attracted to hold the rotating shaft in place. In this invention, at least one of the rotor 16 and the stator 26 (the rotor in the example of FIG. 8) is provided with three sets of attractive magnets, as well as the other magnet (the stator in the example of FIG. 8) that repel the magnet. magnet 2
1 ₄ is provided in the circumferential middle of adjacent magnets 21 ₁ and 21 ₃ of the one (rotor).
An intermediate magnet may be provided between each magnet of the rotor. If the intermediate magnet 21 ₄ is not provided, for example, a person attempting to pass through the gate passage 3 rotates the arm 5 ₁ to 60° in the closed position, then stops passing and retreats without touching the arm 5 ₁ . Or, if the arm 5 ₁ is rotated up to 60 degrees and passes without rotating the arm, the magnets of the rotor 16 and the magnets of the stator 26 are located between each other magnet, and the magnets between each magnet are Since the suction forces are balanced, the rotary shaft 11 does not return to its normal position and stops, impairing the passage control and restriction functions of the turnstile. However, when the intermediate magnet 21 ₄ is provided, when the arm 5 ₁ is rotated up to 60 degrees as described above, this medial diagnosis magnet generates a repulsive force with the rotor magnet, so the rotor It is biased clockwise or counterclockwise and does not form a dead center. Therefore, the rotation angle of the rotating shaft 11 is
When the angle is less than 60 degrees, it can be returned to the original position, and when it exceeds 60 degrees, it rotates forward to the next position, so when either arm is in a horizontal position, it can be rotated completely through the gate passage. cut off. The rotating shaft 11 is preferably inserted between the rotor 16 and the bearing 8 through a sleeve 28 having a disc 27 integrally formed therein;
By attaching the key 29 and pin 30, it is fixed and can rotate together with the rotating shaft.
The disk 27 has semicircular notches 31 on its circumferential surface at equal intervals in the circumferential direction. The angle formed by the straight line connecting the center of rotation of the disk and the adjacent notch is
It is 30°. Further, as shown in FIG. 7, on one side of the disk 27, there are three straight lines extending radially from the center of rotation of the rotating shaft 11 at intervals of 120 degrees in the circumferential direction. The cam groove 32 has a symmetrical substantially swollen regular triangular shape. The notches 31 on the disc can be freely engaged and disengaged from solenoids 33 and 33e arranged on both left and right sides of the disc, and one notch at a predetermined position on the disc through link means by the operation of the solenoid. Together with the engaged rollers 34 and 34e, a locking mechanism for the rotating shaft 11 is constituted. As will become clear from the description below, this locking mechanism not only locks the rotary shaft in a fixed position, but also regulates the direction of rotation of the rotary shaft, that is, the direction of passage through the gate passage. The solenoid 33 is attached to the back side of the mounting plate 6 on the left side of the disk 27, and a lever 36 pivotally attached to the upper end of the plunger 35 at an intermediate portion is pivotally supported by a pin 37 projecting from the mounting plate. An arm 38 is also pivotally supported at one end of the pin 37, a tension spring 39 is tensioned between the arm and one end 36a of the lever 36, and a stopper is provided between the pin 37 and one end of the lever 36. 40 is provided to protrude from the rober 36 so as to limit rotation of the arm. The arm is pin 3
7 and the center of rotation of the disk 27, the lorata 34 extends toward the peripheral surface of the disk on the side closer to the counterclockwise direction than the straight line connecting the center of rotation of the disk 27, and has a lorata 34 at its tip that can fit into the notches 31 of the disk. It is rotatably provided. When the solenoid 33 is not energized (OFF), the plunger 35 is projected by the compression spring 41 (described later), and the lever 36 rotates clockwise around the pin 37, so that the arm 3
7 is locked to the stopper 40 and rotated together with the lever, so that the roller 34 is moved outward from the notch 31 of the disc 27. Also, solenoid 3
3 is energized (ON), the plunger 35 is attracted and applies a force to the lever 36 to rotate it counterclockwise. Between the other end 36b of the lever 36 and the mounting plate or solenoid 33, there is a compression spring 41 whose one end is fixed to the other end of the lever, a piston 42 connected to the other end of the spring, and a piston 42 connected to the other end of the spring. A damping means 44 is attached which consists of a cylinder 43 which is a loose fit and is fixed to the mounting plate or solenoid. Therefore, when the solenoid 33 is turned on, the roller 34 is gently pressed toward the circumferential surface of the disc 27. When the roller 34 corresponds to the notch 31 in the disc as shown in FIG. 10, the arm 38 is biased by the tension spring 39, so the roller 34
engages with the notch 31. And arm 3
8 extends from the fulcrum 37 in the counterclockwise direction of the disk, thereby preventing clockwise rotation of the disk 27. However, since the arm extends in the forward direction with respect to the counterclockwise rotation of the disk and is rotatably supported by the pin 37, the disk can freely rotate in the counterclockwise direction. . That is, speaking only of the solenoid 33, when the solenoid is turned on, it only allows the rotating shaft 11 to rotate counterclockwise (in FIGS. 5 and 6), prevents clockwise rotation, and turns it off.
In this case, the rotating shaft 11 is free to rotate in either direction. The right side of the disc 27 also has the above-mentioned solenoid 33,
Lever 36, pin 37, arm 38, roller 3
4, and a combination having the same configuration as the combination of the tension spring 39 is provided symmetrically. In FIG. 5, the members corresponding to the members of the combination on the left side are indicated by adding e to the former reference numerals, and detailed explanations thereof will be omitted. It is omitted in FIG. In the combination on the right, when the solenoid 33e is ON, the rotation shaft 11
Only clockwise rotation (in FIGS. 5 and 6) is allowed, and counterclockwise rotation is prevented. and,
When the solenoid 33e is OFF, the rotating shaft can freely rotate in either direction. The above solenoids 33 and 33e are usually both
It is in the ON state and prevents rotation of the rotating shaft 11 in any direction. That is, the turnstile holds the rotating shaft 11 in place with one arm _{5 1} in the closed position as shown in FIGS. It also prevents the arm from rotating. The turnstile unlocks the locking mechanism and allows the arm and rotating shaft to be rotated by the customer's manual push.In order to allow the customer to pass, a signal is sent from the control unit to allow clockwise rotation or counterclockwise rotation. Based on the former, the solenoid 33 outputs a signal.
and the solenoid 33e based on the latter, respectively.
It's starting to turn off. In other words, in a turnstile equipped with a mechanism for locking the rotating shaft clockwise and counterclockwise, passage in a predetermined direction is controlled by either the CW rotatable signal or the CCW rotatable signal and the gate signal. is possible. The gate opening signal can be given from a location away from the gate box 2, such as from a control room, but in general, various gates automatically read the ticket that the customer inserts into the gate box when the customer passes through, and determine that the ticket is valid. It is designed to sometimes issue a gate opening signal. In this way, tickets inserted by customers can be automatically read and
In order to operate the locking mechanism based on the determination, as shown in FIG.
Alternatively, gate rotations 49 and 49e are provided whose output conditions are satisfied by the CCW rotation enable signal 48e, respectively, and the power supply switches 50 and 50 of the solenoid 33 or 33e are turned on based on the output of each gate circuit.
Set the drive circuits 51 and 51e that turn off e,
The drive circuits 51, 51 are driven by the output from the rotation angle detector 52 which detects that the rotating shaft 11 has rotated by a predetermined angle.
It would be better if it was configured to reset e. For example, the control unit 47 corresponds to the ticket slots provided at the front and rear of the gate box 2, and outputs a CW or CCW rotatable signal depending on which side the ticket is inserted into first, or it is operated manually by an attendant. Alternatively, it may be a remotely controlled switch. As described above, one solenoid is turned off based on the gate open signal 46, and the rotating shaft 11 is turned off.
After being made to be able to rotate clockwise or counterclockwise, when the customer slightly pushes the arm ₅₁ in the chain position, the robot may stop passing for some reason and retreat. Notches 31 of the disc 27...
As shown in Fig. 12, the angles are equally spaced by 30 degrees clockwise and counterclockwise from the reference angles (0°, 120°, 240°) corresponding to arms ₅₁ to ₅₃ , respectively. There are three for each arm. The other solenoid is always turned on.
Therefore, if the customer stops pushing when the rotation angle of the customer's arm ₅₁ is less than about 30 degrees, the rotating shaft will be rotated by the attractive force of the magnets of the rotor 16 and stator 26 of the above-mentioned rotating shaft fixed position holding means. 11 is reversely pivoted and the arm ₅₁ returns to the closed position, allowing the customer to retreat from the gate passage. However, when the customer presses his hand further and the rotation angle of the rotating shaft reaches approximately 30 degrees, the roller on the solenoid side that is turned on engages with the notch in the disc, so
Reverse rotation of the rotating shaft 11 is no longer prevented. Furthermore, when the force applied while the rotation angle of the rotating shaft exceeds 30 degrees and is less than 90 degrees, the roller 34 or 34e comes into contact with the convex curved surface of the disk 27.
When the force is removed from the arm when the rotation angle is less than 60°, the rotation axis is reversed up to 30° due to the repulsive action of the intermediate magnet, and when the force is removed from the arm when the rotation angle exceeds 60°, the intermediate magnet The rotating shaft 11 continues to rotate normally due to the repulsive action. Typically, a person attempting to pass through a gate passage will forcefully push the arm in the closed position. Therefore, the rotating shaft 11
begins to rotate by overcoming the attractive force of the magnets of the rotor and stator, and the rotating shaft 11, disk 27 and rotor 1
Due to the moment of inertia due to the weight of 6, etc., the rotating shaft easily rotates with momentum exceeding 60 degrees. Then, the rotation continues due to the repulsive action of the intermediate magnet, and when the rotation angle exceeds 90 degrees, the attractive force between the rotor and stator magnets increases again, so the arm that was in the closed position (home position) is moved halfway. Without stopping, rotate 120 degrees at once until the next arm reaches the closed position. The solenoid that was turned OFF is turned ON again when the rotation angle of the rotating shaft exceeds 90 degrees, so that when the rotation axis rotates 120 degrees, the roller 34 or 34e corresponding to that solenoid turns into a disc. 27 to lock the rotating shaft again. Next, the relationship between the solenoids 33 and 33e and the rotation angle detection of the rotation shaft 11 by the rotation angle detector 52 will be explained based on FIGS. 12 and 13. In the gate standby state, solenoid 3
3 and 33e are both turned on and are suctioning, and the rollers 34 and 34e lock the arm engaged with the notch in the disc 27. When a CW rotation enable signal is issued from the control unit, only the solenoid 33 is turned off when a gate open signal is output from the discriminator for the ticket inserted into the gate box, so the clockwise rotation of the rotating shaft is prevented. It becomes possible. When a CCW rotation enable signal is issued from the control section, only the solenoid 33e is turned off, and the rotating shaft becomes ready for counterclockwise rotation. The rotation angle detector 52 is provided at a distance in the circumferential direction of the disk 27, and is provided by a notch in the disk.
It has three switches sw ₁ , sw ₂ , and sw ₃ that are turned off, and the signal state of each switch as the disk 27 rotates is coded as follows.

[Table] Figure 12 shows the state of code 100. The device angle detector has a code signal order of 100→000
→001→010→100, it is detected that the disc 27 is rotating clockwise, and when the order is reversed, it is detected that it is rotating counterclockwise. It also detects that the disk has rotated 30 degrees each time one code changes. Then, when the rotation angle reaches 60° to 90°, the passage of one passenger is confirmed. Furthermore, when a rotation angle of 90°, 210°, or 330° is detected, the solenoid 33 or 33e is turned ON again in order to give a reset signal to the drive circuits 51 and 51e in FIG.
At rotational axes of 120°, 240°, and 360°, it is engaged with the roller 34 or 34e or the notch in the disk and locked again. FIG. 13 shows the mutual relationship between the rotation direction of the rotation shaft, the rotation angle, and the solenoid rotation angle detection switch. This figure exemplifies the case where two customers pass in the left direction and one customer passes in the left direction in FIG. As mentioned above, when the rotation angle of the rotating shaft 11 is from 90°
In the range up to 120°, the attractive force of the rotor and stator magnets gradually increases, so if no measures are taken, the device shaft will rotate rapidly, remain in the open position, and close together with the rotating shaft. The customer can be hit hard in the back by the next arm that comes into position. In order to prevent this, the turnstile according to the present invention is equipped with the following speed reduction mechanism. The speed reduction mechanism has a pin 24 on the back of the mounting plate 6.
A fluid cylinder 53 has one end pivotally connected to the piston rod 53, a bell crank 55 has one end pivotally connected to the tip of the piston rod 54 of the cylinder, and is pivotally supported by the pin 37 at the bent portion, The rotating disk 2 is held freely and
The roller 56 is rotatably fitted into the cam groove 32 of No. 7. When the rotating shaft 11 is in a fixed position (i.e.
when the arm is in the closed position), the roller 56
is located at the apex of the approximately triangular cam groove. Since the cam grooves are reversely symmetrical to each other with respect to the three rays having an interval of 120 degrees as described above, each time the rotating disk 27 rotates 120 degrees in either the left or right direction, the roller 56 makes one reciprocation in the far and near direction with respect to the center of rotation. Therefore, the piston rod 54 reciprocates in and out of the cylinder 53 via the bell crank 55. The cylinder 53 is the piston rod 5
4, no load is applied to the piston when it enters.
Therefore, when the rotating tree 11 rotates approximately 60 degrees from the home position, the rollers 56 do not apply any load to the rotating shaft. However, the piston rod 54 is
When the piston moves forward, a load is applied to the piston. Therefore, when the rotating shaft 11 exceeds about 60 degrees, it is strongly urged to move toward the next fixed position by the repulsive force and attractive force of the magnets of the rotor and stator. The load is applied to decelerate the vehicle. In this way, the next arm coming into position is prevented from striking a customer passing through the gate passage from behind. While the customer does not insert a ticket into the ticket slot of the gate box, both solenoids 33, 33e are in the ON state, the two rollers 34, 34e engage with the notches in the rotating disk, and the rotating shaft 11 is turned on. Cannot rotate in either direction. That is, the turnstile is locked in place. In this state,
If an emergency occurs in a facility where a gate using this turnstile is installed, it is desirable to be able to freely pass through the gate immediately. For example, a switch to be operated in the event of an emergency is provided in the monitoring room, and when the switch is operated, a set signal is input to the turnstile drive circuits 51 and 51e, and both solenoids 33 and 33e are turned off.
It can be configured to be In addition, when the turnstile is locked in place, for example, a customer who attempts to evacuate in an emergency without the above-mentioned panic response switch being operated,
Or a customer who tries to illegally pass through the gate passage.
It is conceivable that an attempt may be made to forcefully push the arm that is in the closed position to open it. In such a case, each arm 5
₁ , 5 ₂ , and 5 ₃ are very firmly connected to the hub 12 and rotating shaft 11 , the excessive load applied to the arms is transmitted to the locking mechanism, causing the rollers 34 ,
34e, the pivot parts of the pins 37, 37e, etc. are easily damaged. Repairing and replacing these locking mechanisms requires a lot of effort. To prevent this, one way is to ensure that the solenoid 14 that connects the arm to the hub
A method is provided to provide a structure that will fail or fall off when excessive loads are applied to the arm. The other one, as shown in Figure 4, is
A cap-shaped friction wheel 57 is mounted on the rotating shaft 11 through the center between the bearing 8 and the hub 12, and is fixed to the rotating shaft with a key 58 and a bolt 59. The spring plungers 60 are arranged at equal intervals in the circumferential direction.
A ball 61 held at the tip of the spring rig plunger 60 is made to bounce toward a groove 62 provided at the peripheral end of the friction wheel 57. The spring plunger 60 is, for example, a compression spring 63.
is telescopically inserted into a tube 64, and a ball 61 is rotatably held at the tip of the spring.
The other end of the cylinder 64 is a convex portion 6 provided on the inner surface of the hub 12.
The ball 61 is attached to the hub by contacting and fixing to the friction wheel 57, and the ball 61 is always strongly pressed against the friction wheel 57. As a result, a strong frictional force acts between the hub 12 and the friction 57, and normally the hub 12 and thus the arm rotate together with the rotating shaft 11. However, when an excessive load is applied to the arm, the ball 61 of the spring plunger rolls on the friction wheel 57 and the hub is rotated with the rotation axis remaining. Accordingly, the arm is rotated from the closed position to the open direction, allowing emergency evacuation or unauthorized passage passengers to pass through the gate. However, no damage is done to the locking mechanism. The lock is released by turning OFF the solenoids 33 and 33e, so in the event of a large-scale accident such as a power outage, the lock will be automatically released, ensuring safety. be done. In the above embodiment, the magnets that generate magnetic energy that serve as a force for holding the rotating shaft in a fixed position are installed in the rotor and stator, which are separated in the axial direction of the rotating shaft, and the lines of magnetic force of each set of magnets flow parallel to the rotating shaft. It was arranged like this. This arrangement has the advantage that the rotor and stator have substantially the same structure and can be manufactured in the same manner using similar members. However, the present invention is not limited to the above arrangement. Magnetic poles are provided on the outer periphery of a disk-shaped rotor fixed to the rotating shaft, facing in the centrifugal direction.A donut-shaped stator is fixed on the diametrically outer side of the rotor, and the magnetic poles are placed on the inner periphery of the stator, facing in the centripetal direction. It is also possible to have a magnet arrangement configuration that is directed toward the Further, although permanent magnets were used in the above embodiments, it is clear that electromagnets can also be used. Further, in the above embodiment, three arms are provided protruding from the hub, and each arm is sequentially held in the closed position by rotating the rotating shaft by 120 degrees, but the number of arms may be any number between two and one. , by rotating 360° by an angle equally divided by the number of arms, and by providing the corresponding number of magnets, the same effect as in the above embodiment can be obtained. Further, the turnstile according to the present invention can be used in addition to a gate box, for example, by being attached to a support that is erected in contact with a gate passage. As described above, according to the present invention, the magnetic energy of the magnet that attracts the rotor fixed to the rotating shaft and the stator which is provided in a non-rotatable manner at the fixed position of the rotating shaft is used to maintain the rotating shaft in a fixed position. Therefore, it is possible to obtain a non-contact holding force, and there is no wear on the components due to the rotation of the rotating shaft, and the lifespan is significantly extended compared to the conventional device that combines a coil spring and a cam. . In addition, since the part that generates the holding force is composed of a rotor containing magnets and a stator, the structure is small and simple, and assembly is easy. According to the second invention, a plurality of pairs of magnets that attract each other at fixed positions on the rotating shaft are arranged on both the rotor and the stator, and at least one of the rotor and the stator is arranged on one fixed position on the rotating shaft. Since a repulsive magnet is provided on the other magnet of the rotor and stator at an intermediate rotation angle between the first position and the next fixed position, the arm stops half-way closing the gate passage and closes the gate. The passage control and prevention functions will not be lost. In the above explanation, the term "arm" was used to name the member that is connected to the rotating shaft of the turnstile and controls the passage of people through the gate passage, but this is only for convenience and is limited to rod-shaped arms. That's not the purpose. For example, a plurality of plate-like bodies, lattice bodies, rectangularly bent tubes, rod-like bodies, etc. extending from the ceiling to the floor can be connected to the rotating shaft in a radial pattern to form a revolving door.

Claims (1)

[Scope of Claims] 1. A plurality of arms are attached to one end of a rotary shaft rotatably supported on a mounting plate, and the arms are rotated in the rotational direction, and are sequentially moved to a position where the gate passage is closed and a position where the gate passage is opened as the rotary shaft rotates. and fixing a rotor at the center thereof to the other end of the rotating shaft opposite to the arm with respect to the mounting plate,
The rotor has the same number of magnets as the arms arranged at equal intervals in the circumferential direction of the rotor, and the mounting plate has a disc-shaped or donut-shaped stator that shares a central axis with the rotor. A turnstile according to claim 1, characterized in that a magnet is disposed on the stator of the rotor and attracts the magnets in close proximity to each magnet of the rotor in a fixed position in which each of the arms is in a closed position. 2. At one end of a rotating shaft rotatably supported on a mounting plate, a plurality of arms are provided at equal intervals in the rotational direction, and are sequentially moved to a position where the gate passage is closed and a position where the gate passage is opened as the rotating shaft rotates. fixing the rotor to the other end of the rotating shaft opposite to the arm with respect to the mounting plate, and fixing the rotor at its center;
The same number of magnets as the number of arms are arranged on the rotor at equal intervals in the circumferential direction of the rotor, and a disk-shaped or donut-shaped stator having a common central axis with the rotor is attached to the mounting plate. , the stator is provided with magnets that attract each magnet in close proximity to each magnet of the rotor in a fixed position in which each of the arms is in a closed position; A turnstile characterized in that at least one magnet is provided that repels between the other magnet of the rotor and the stator in one-half of the rotation angle from one position to the next fixed position.
