Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a method for entering and exiting stations, entertainment venues, stadiums, etc. [1]
Control the passage of a large number of customers one by one at a distance of 1-5 m.
The present invention relates to a turnstile used for controlling or restricting the direction of movement.

Generally, a turnstile has several arms protruding from the end of a rotating shaft at regular intervals along a conical surface.
The rotating shaft is tilted at a certain angle, and the arm marked Aj is rotatably supported so as to become approximately horizontal one after another and prevent the passage of customers, and normally the rotation of the rotating shaft marked js'++ is locked. The rotating shaft is unlocked by a gate opening signal, and the arm is made rotatable by a customer's hand push, and the customer is given a feeling of passing by rotating the arm a predetermined angle by hand push; It is configured to lock the rotation of the rotating shaft again when the next arm reaches a horizontal position to prevent the passage of the next customer. If the customer corrects the passage, the arm is returned to the aisle closing position, and after the customer has passed, the next arm is quickly returned to the aisle closing position, and
In order to prevent the passage of FIE and force it to proceed,
Means is used to apply a force to the rotating shaft to keep 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, there is a contact part in the configuration L1
It has a limited lifespan due to wear. In addition, when a combination structure of a coil spring and a cam is used for a bidirectional turnstile, that is, a swing turnstile that provides passage control in the entrance and exit directions, it is possible for customers to pass through the gate passage both when entering and exiting the hot water. The key is to design the shape of the cam so that the arm rotates quickly when entering the gate, and slowly rotates when exiting the gate passage, and the arm rotation is symmetrical in both directions. However, if the cam shape was such that passengers could not pass smoothly, this would hinder the smooth passage of passengers.

The main purpose of this invention is to provide a turnstile that uses magnetic energy to maintain the rotating shaft in a fixed position so that the desired action can be obtained without contact, thereby eliminating wear and extending the service life. do.

The turnstile according to the present invention has a donut-shaped rotor fixed at its center on a rotating shaft to which a plurality of arms separated at a certain angle are fixed, and a similar one-shaped rotor adjacent to the rotor. A stator shaped or disc-shaped is provided parallel to the rotor with its center coincident with the rotor, 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. For this purpose, all the magnets on the stator side are arranged with opposite polarity to the magnets on the rotor.

If the magnets were arranged in this way, for example, in a turnstile with three arms, an ordinary customer could
When the arm in the l-chain position is rotated to 600 degrees, when passing through +t and retreating, or when a thin customer rotates the arm to 600 degrees.
If the rotor magnet and the stator magnet are rotated to 600°, the rotor magnet and stator magnet
Since they exist at equal intervals of 0, a dead center occurs, and the D-ta, and therefore the rotation axis, cannot rotate to the fixed position in any direction, and the arm does not function as a barrier to passage. There is a risk that this may occur.

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 its normal orientation due to a dead center caused by each set of attracting magnets. The second purpose is to provide

Next, the present invention will be explained in detail based on the drawings.

Figure 1 is an example of case 1 with a turnstile installed.
-A side view, and FIG. 2 is a side view of the same. In Figures 1 and 2, the turnstiles generally indicated by ■ are game
1. Passing one person at a time through a gate passageway 3 formed between a similar gate box or fence or wall installed on the opposite side with respect to the turnstile 1 of this gate box 2, It is used to control the

The gate box 2 has four parts 4 in the center of the front, and the base of the turnstile is installed on the upper slope of the four parts so that the rotation axis (described later) has an angle of 45 degrees with respect to the vertical line. Arms 52 and 53 existing at the base of the style and in the open position do not protrude into the gate passage 3 from the front of the gate box 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. The mounting plate 6 is brought into contact with the upper sloped surface 4a of the four parts 4 of the gate box from the outside, and is fixed to the gate box by means of fixing means such as Pol, Nando, or other fixing means.

The Kate Bonox 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, and a bolt lO is passed through a flange 9 formed at one end of the bearing, and by screwing this into the mounting plate 6, the bearing 8 is attached to the mounting plate. It is fixed.

The bearing 8 has a rotating shaft 11 that protrudes both inside and outside of the mounting plate 6.
is penetrated and rotatably supported.

A bolt 12 is fixed to one end of the rotary shaft 11 on the outside from the number plate 6, and a conical surface having an angle of 45° with respect to the axis of the rotary shaft 11 is fixed to the rotary shaft 11 by a bolt 13. Three arms 5. extend along the phase T'i□ with a spacing of 1200 in the circumferential direction. , 5□.

53 are provided. Each arm is press-fitted into a socket 14 formed integrally with the hub 12 or fixed by a screw 15. A tornado-shaped rotor 16, which is one component of the means, is fitted in a hole 17 provided at its center and fixed by a washer 19 and a nut 20. It has holes at positions spaced apart by 1200 in the circumferential direction of a concentric circle, and each hole has a permanent magnet 21., 21.
2.213 is fitted, and magnetically non-permeable disks 22.23 are joined to the inner and outer surfaces of the rotor. Each magnet 211
+ 212 + 213 are arranged so that the lines of magnetic force flow parallel to the axis of the rotating shaft 11 and the same magnetic poles of each magnet face in the same direction.

One end of a support member 24 extending diametrically outside of the rotor 16 to the opposite side of the rotor from the mounting plate is fixed to the mounting plate 6, and the other end of the support member 24 has a support member 24 having a diameter slightly larger than the outer diameter of the rotor. Ring-shaped holding member 25 having a diameter
is fixed so that its center coincides with the center of the rotating shaft 11, and a stator 26 is fixed inside the holding member 25. The stator 26 is Ff with the njJ rotor 16.
Three permanent magnets having a similar configuration are arranged at intervals of 1200 in the circumferential direction so that the lines of magnetic force flow parallel to the rotating shaft 11.

However, the permanent magnets of the stator are arranged so that the polarity ζ11 of the magnets of the rotor is oriented toward the rotor. Components of the stator corresponding to each component of the rotor are indicated by adding e to the former symbol. In this invention, as described above, the rotating shaft fixed position holding means has the rotating shaft 11"-" at the center. A rotor 16 is fixed to the rotor and has permanent magnets arranged with the same polarity in the same direction at intervals of 120' on the circumference. The stator 26 includes a stator 26 having permanent magnets arranged at intervals of 12 (+') above and with magnetic poles different from the permanent magnets of the rotor facing toward the rotor.

As shown in FIGS. 1 and 2, when any one of the arms 5 is in a horizontal state and closes the cage passage 3, each magnet of the rotor 16 is connected to the stator. 26
The rotating shaft 11
is held in place. When attempting to pass through the gate passage 3, for example, to the left in FIG. When the arm 5. is rotated to the position of the cage 5□, the arm 5. retreats from the cage passageway 3 into the fourth section 4, so that the customer can pass through the cage, and the arm 53 rotates and becomes horizontal. , to prevent the next customer from passing.In this process, the arm 51 is pushed with a force greater than the attraction force of the three silk magnets of the rotor 16 and stator 26, and the rotating shaft 11 begins to rotate. The magnet 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 1200, the rotor 1
Different pairs of magnets on the stator 26 and the stator 26 pull 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 attracting magnets, and the other (the stator in the example of FIG. 8) is provided with three sets of attracting magnets.
The magnet 214, which repels the magnet 21., is connected to the adjacent magnet of the one (rotor), for example 21. and 213 in the circumferential direction.

The intermediate magnet may be provided between each magnet of the rotor. If the intermediate magnet 214 is not provided, for example, a person who is passing through the case 1 and the passage 3 may move the arm 51 in the closed position at 600 degrees.
After rotating until 5. If you move backward without touching it, or if you rotate your arm from 5 degrees to 60 degrees and pass it without rotating it, the magnets of the rotor 16 and the stator 26 will each be in the middle of the other magnet. exists, and the attractive force between each magnet is balanced, so the rotation l1lI
lll will stop without returning to the normal position 1, and the turnstile passage control and restriction functions will be impaired. However, if the upper station and intermediate magnet 214 are provided, the arm 5
1 is 60'-! When rotated, this intermediate magnet generates a repulsive force with the rotor magnet, so the rotor is biased clockwise or counterclockwise, and no dead center is formed. , rotation mft 11 has a rotation angle of 60
When it is less than 0, it can be returned to its original position,
In addition, since the blade rotates forward beyond 60 degrees to the next fixed position, one of the arms must be in a horizontal position to completely block the passage.

Preferably, between the rotor 16 and the bearing 8, the rotary shaft 11 is pushed through a sleeve 28 integrally formed with a disk 27, and a key 29 and a bottle 30 are inserted into the rotary shaft 11.
By attaching it, it is firmly fixed and can be rotated with the rotating shaft. The disk 27 has semicircular notches 31 on its circumferential side 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 notches is 300. Also, as shown in FIG. 7, one of the disks 27 has a reaction force with respect to three straight lines extending radially from the center of rotation of the rotating shaft 110 in the circumferential direction at intervals of N11 of 120°. It has a cam groove 32 in the shape of a substantially swollen equilateral triangle.

The notch 31 on the disc can be freely engaged and disengaged from a notch at a predetermined position on the disc via the solenoids 33 and 33e arranged on the left and right sides of the disc, and a 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 a later explanation, this locking mechanism not only locks the position of the rotary shaft, 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 mounting plate 6 on the left side of the disc 27.
The lever 36, which is attached to the back side of the plunger 35 and pivoted at the middle part to the child end of the plunger 35, is attached to a lever 36 that is attached to the rear surface of the
It is centered on 37. An arm 38 is also pivotally supported at one end of the pin 37, and a tension spring 39 is tensioned between the pinot 37 and one end 36a of the arm lever 36. The lever 36 is configured to limit the rotation of the stopper 40 or the arm at the
It is installed protrudingly. The arm extends toward the peripheral surface of the disc on the side that is closer to the counterclockwise direction than the straight line connecting the rotation center of the pin 37 and the rotation center of the disc 27, and its tip fits into the notch 31 of the disc. A wet roller 34 is rotatably provided.

When the solenoid 33 is not energized (OFF), the plano jar 35 is projected by the compression spring 41 (described later), and the lever 36 is rotated clockwise around the bin 37, so that the arm 38 is 40 and rotates with the roller 34.
is moved outward from the notch 31 of the disc 27. still,
When the solenoid 33 is turned on (ON), the flanger 35 is attracted and applies a force to rotate the valve <-36 in the counterclockwise direction.

...-36 other end 36b and number board 6 or solenoid 3
3, there is a compression spring 41 fixed to the other end of the spring 41, a piston 42 connected to the other end of the spring 41, and the piston 42 connected to the other end of the spring 41.

A buffer means 44 is attached, which is a cylinder 43 that is loosely fitted with a cylinder 43 and is fixed to a mounting plate or a 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 disk as shown in FIG.
engage with. Since the arm 38 extends from the fulcrum 37 in the counterclockwise direction of the disk, it prevents the disk 27 from rotating in the clockwise direction. However, since the arm (d) extends in the forward direction with respect to the counterclockwise rotation of the disc and is rotatably supported by the pin 37, the disc cannot freely rotate counterclockwise. I can do it.

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 Fig. 5.6), prevents clockwise rotation, and turns it off. In this case, the rotating shaft 11 is free to rotate in any direction.

Also on the right side of the disk 27, a combination having the same configuration as the above-described combination of the solenoid 33, lever 36, pin 37, arm 38, roller 34, and tension spring 39 is provided symmetrically. In FIG. 5, the members corresponding to the members in the left-hand combination are only shown by adding e to the former reference numerals, and detailed explanations are omitted. It is omitted in FIG. In the combination on the right, when solenoid 33e is ON, rotation axis 1
1 (in Figure 5.6) only allows clockwise rotation and prevents counterclockwise rotation. When the solenoid 33e is OFF, the rotating shaft can freely rotate in any direction.

1- The lunoids 33 and 338 are normally both in the ON state, and rotation of the rotating shaft 11 in either direction is caused by lfI[
I'm alone in tl. That is, the turnstile holds one arm 51 in the closed position as shown in FIGS. 1 and 2, and holds the rotating shaft 11 in place, so that even if a person leans on or pushes the arm 51, the arm 51 remains closed. prevents it from rotating.

The turnstile unlocks the locking mechanism and allows the customer to rotate the arm and rotating shaft by pushing the customer's hand. In order to allow the customer to pass, the control unit sends a rotatable signal in the J1 direction (example) or in the counterclockwise direction ( CaW) A rotatable signal is output, and the solenoid 33 is turned off based on the former, and the solenoid 33e is turned off based on the latter. In other words, a mechanism for locking the rotating shaft in a clockwise direction and a counterclockwise direction (in the developed turnstile, passage in a predetermined direction is controlled by one of the above-mentioned chronological rotation enable signal or CCW rotation enable signal and a gate signal). is possible.

The gate opening signal can also be given from a location remote from the gate box 2, such as a control room.In general, various gates automatically read the ticket that the customer inserts into the gate box when the customer passes through, and the ticket is validated. When a determination is made, a gate open signal is issued. In this way, in order to operate the locking mechanism by automatically reading and determining the ticket inserted by the customer, as shown in FIG. 1. Open signal 46 and CM rotation i'F]' signal 4 from control unit 47
8 or CaW rotatable signal 48e are provided, and gate circuits 49 and 49e whose output conditions are satisfied respectively are provided, and the solenoid 33 or 33 is
The drive circuits 51 and 51e are turned off to turn off the power-on switches 50 and 50e, and the drive circuits 51 and 51e are reset by the output from the rotation angle detector 52 that detects that the rotating shaft 11 has rotated by a predetermined angle. Sushi HJ: I. For example, the control unit 47 may be one that outputs a saw or ■w rotatable signal depending on which side of the gate box 2 can be fully loaded with tickets, corresponding to the ticket slots provided at the front and rear of the gate box 2, or it can be operated manually by an attendant. It may also be a switch that is manually operated or remotely operated.

As described above, one solenoid is turned off based on the gate release signal 46, and the rotating shaft 11 is rotated clockwise or (
After the bow 1 is allowed to rotate counterclockwise, the customer returns to the closed position IA.
When the arm 51 located in the front is slightly pushed LL, the passage may be stopped and retreated for some reason. As shown in FIG.
, from 24(10), 3 for each arm at equal intervals of 30' clockwise and counterclockwise, respectively.
Each item is provided individually.

The other solenoid is always turned on.

Therefore, when the customer stops pushing when the rotation angle of the customer's arm 51 due to manual pushing is less than about 30', the rotating shaft 11 is rotated by the attraction force between the rotor 16 and the magnet of the stator 26 of the above-mentioned rotating shaft fixed position holding means. Reverse arm 5. returns to the closed position, allowing customers to retreat from the gate aisle. However, when the customer pushes the shaft further and the rotation angle of the rotating shaft reaches approximately 30',
If the roller on the solenoid side that is ON does not fit into the notch in the disc, the rotating shaft 11 will no longer be able to reverse rotation.Also, if the rotation angle of the rotating shaft exceeds 30° and is less than 90° When the force applied to the arm during the rotation angle is removed, the roller 34 or 34e is in contact with the convex curved surface of the disc 27, so when the force is removed from the arm at a rotation angle of less than 600 degrees, the intermediate magnet The axis of rotation is reversed at the 30° groove due to the repulsive action, and when the force is removed from the arm when the force exceeds 600°, the axis of rotation 11 continues to rotate iE due to the repulsive action of the intermediate magnet.

Typically, a person attempting to pass through a Kate passage will forcefully push the arm in the closed position. Therefore, the rotating shaft l] overcomes the attractive force of the magnets of the rotor and stator and begins to rotate, so the rotating shaft easily loses 600 mm due to the moment of inertia due to the weight of the rotating shaft 11, disk 27, rotor 16, etc. With the momentum to overcome, he rolled 1111. Then, the rotation continues due to the repulsive action of the intermediate magnet, and when the rotation angle exceeds 900, the attractive force between the rotor and stator magnets increases again, so the arm that was in the closed position (normal position) stops midway. In particular, the next arm reaches the closed position after 1200 revolutions.

01i"Ti"aThe solenoid that was turned on will be turned ON again when the rotation angle of the rotating shaft exceeds 9()0.As a result, when ]2O2 rotates, the solenoid will be turned on again. The corresponding roller 34 or 1d34e is the disk 2
7 to lock the rotating shaft again.

Next, the relationship between control of the solenoids 33 and 33e and detection of the rotation angle of the rotation shaft 11 by the rotation angle detector 52 will be explained based on FIGS. 12 and 13.

In the standby state of game 1, the solenoid 33°33
Both e are turned on and are suctioning, and the roller 34°34
e engages with a notch in the disc 27 to lock the arm. When the y-rotation enable signal is output from the control unit, when the gate release signal is output from the discriminator for the ticket inserted into the gate box, only the solenoid 33 is turned off, and the so-called direction of the rotation axis is changed. rotation is possible. When the control section outputs the rotatable signal, only the solenoid 33e is turned off, and the rotating shaft becomes ready to rotate in the counterclockwise direction.

The rotation angle detector 52 has three switches Sw+, SW2, and SW3 that are spaced apart from each other in the circumferential direction of the disk 27 and are turned off by a notch in the disk. The signal state of each switch is coded as follows.

FIG. 12 shows the state of code 10 (J).

The rotation angle detector has a code signal order of 100→000→(
+ When 01→010→100, the disc 27 is
If the order is reversed, it is detected that the rotation is in the counterclockwise direction. Also, each time the code changes, it is detected that the disk has rotated 300 times. In this way, as the rotation angle progresses from 6()0 to 900, one passenger is barely allowed to pass. Also, the rotation angle is 9
0', 2] (10, 3300, the solenoid 33 or 33e is turned on again in order to give the reset signal 1-Q to the drive circuits 51 and 51e in FIG.
When the rotation axis reaches 1200°, 240° and 3600°, the roller 34 or 34e engages with the notch in the disc and is locked again.

Figures 1 and 3 show 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 person passes in the right direction in FIG. 1.

- As shown in the series, the rotation angle of the rotating shaft 11 is from 900 to 12
In the 11ii'J range of 004, the attractive force between the rotor and stator magnets gradually increases, so if no measures are taken, the rotation #t+t+ rapidly rotates and remains in the open position for one rotation. The customer may be hit hard in the back by the next arm that reaches the closed position as the axis rotates.

In order to prevent this, the turnstile according to the present invention is equipped with the following deceleration mechanism. The deceleration mechanism consists of a cylinder 53, one end of which is pivotally attached to the back of the plate 6 with a number J, and one end of which is pivotally attached to the tip of the piston rod 54 of the cylinder, and at the bending part. A bell crank 55 is pivotally supported by the pin 37, and a roller 5 is rotatably held at the other end of the bell crank and is fitted in the cam groove 32 of the rotary disk 27 so as to be freely movable.
It consists of 6.

When the rotating shaft 11 is in the normal position (ie, when the arm is in the closed position), the roller 56 is at the apex of the approximately triangular cam groove. And the cam groove is 1 as mentioned above.
Since it is invertedly symmetrical with respect to the three rays having an interval of 200 degrees, when the rotating disk 27 rotates 1200 degrees in either the left or right direction, the roller 56 is far away from the center of rotation. Go back and forth in the direction. Therefore, bell crank 5
The piston rod 54 reciprocates with respect to the cylinder 53 from 5 to 1. Cylinder 53 is screw l-/rod 5
When 4 enters, no load is applied to the biston. Therefore, when the rotating shaft 11 rotates from the home position to about 600 degrees, the roller 56 does not apply any load to the rotating shaft. However, when the piston rod 54 advances from the piston 53, a load is applied to the piston. Therefore, rotation i#111(d
: Approximately 6 (after passing 1, the repulsive force of the rotor and stator magnets and the first-stage attractive force force the rotor to move toward the next fixed position, but the roller 56 applies a load to the rotating shaft 11). −C decelerates. Thus, next “il (I′L
! This prevents the arm that is about to arrive at time t from hitting the customers who are swirling around the gate passageway from behind.

While the customer does not insert the ticket into the ticket slot of the gate box (r
Both solenoids 33 and 33e are in the ON state, and the two rollers 34 and 34e engage with the notches of the rotating disk, so that the rotating shaft 11 cannot rotate in either the left or right direction.

That is, the turnstiles are locked in place. In this state, if an emergency situation occurs in a field where a gate using this turnstile is installed, it is desirable to be able to freely pass through Game 1 immediately. For example, a switch that can 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 the solenoids 33 and 33e are both set to O'Ii''F. It can be configured so that

For example, when the turnstiles are locked in place, a customer attempts to evacuate without the panic response switch described in 2.
It is conceivable that a customer attempting to pass through M-way may forcefully push the arm that is in the closed position to open it. In such a case, if each arm 51, 5□, 53 is very firmly connected to the hub 12 and rotating shaft 11, the LJ
A large load is transmitted to the lock mechanism, and the pivot parts of the rollers 34, 34e, pi, /37+37e, etc. are likely to be damaged. Repairing and replacing these locking mechanisms requires a lot of effort. To prevent this, fd,
For one thing, the material 14 that connects the arm to the hub is made of material that will break when an excessive load is applied to the arm.
How to make the structure fall off is taught.

In the other one, as shown in FIG.
1-H, a cap-shaped friction wheel 57 is installed 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. Spring plungers 60 are provided at regular intervals in the circle 1%lj)'' direction, and a ball 61 held at the tip of the spring plunger 60 is bounced 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, and the other end of the tube 64 is fixed by coming into contact with a convex portion 65 provided on the inner surface of the hub 12. As a result, the ball 61 is constantly being strongly pressed against the friction wheel 57.

As a result, a strong frictional force acts between the hub 12 and the friction wheel 57, and normally the huff 12 and therefore 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 moves to the friction wheel 57.
The bowl hub is rotated by rolling - and leaving a rotating shaft. Accordingly, the arm is rotated from the closed position towards the open position, allowing emergency evacuation or unauthorized passage passengers to pass through the gate. However, there was no damage to the locking mechanism.

The lock is released by turning off the Lunoids 33 and 33e, so in the event of a major accident such as a power outage, the lock will be automatically released, ensuring safety. σreru.

In the above embodiment, four magnets that generate magnetic energy, which serve as a force for holding the rotating shaft in a fixed position, are installed between the rotor and the stator, which are aligned 1@ in the axial direction of the rotating shaft, so that the lines of magnetic force of each set of magnets are aligned with the rotating shaft. Arranged so that they flow parallel to each other. This arrangement has the advantage that the rotor and stator have substantially the same structure and can be manufactured in the same manner using the same portion 4J. However, in this invention, "2 configuration 1+i
It is not limited to Magnetic poles are provided on the outer periphery of a disk-shaped rotor fixed to the rotating shaft, facing in the centrifugal direction, and a donut-shaped stator is fixed on the diametrically outer side of the rotor L1. The magnetic poles are placed on the inner periphery of the stator in the centripetal direction It is also possible to have a magnet arrangement with the magnets facing toward each other. Further, although permanent magnets were used in the embodiments described in 1-, it is clear that electromagnets can also be used.

Furthermore, in the above embodiment, three arms are provided protruding from the hub, and each arm is held in the closed position sequentially by rotating the rotor I in one rotation by 1200 degrees. The same effect as in the above embodiment can be obtained by using a book and rotating it by an angle equal to 3600 divided by the number of arms, or by providing a corresponding number of magnets. Furthermore, the turnstile according to the present invention can be used in addition to the gate box, for example, by being attached to a support that is erected in contact with the gate passage.

” - As mentioned above, according to the present invention, the force for holding the rotating shaft in a fixed position is provided by a magnetic force key of a magnet that attracts the rotor fixed to the rotating shaft and the stator that is provided so as not to rotate at the fixed position of the rotating shaft. Since it is configured to be used, is it a non-contact holding force?
Therefore, there is no wear of the structural members due to the rotation of the rotary shaft, and the life of the device is significantly extended compared to the conventional device using a combination of a coil spring/da and a cam. Furthermore, since the part that generates the holding force is composed of a rotor and a stator containing built-in magnets, the structure is small and simple, and assembly is easy.

Further, according to the second invention, a plurality of pairs of magnets that attract one phase H at a fixed position of the rotating shaft are disposed in both the rotor and the stator, and at least one of the rotor and the stator is provided with Since a magnet is provided that acts repulsively on the magnets of the rotor and stator capacity described in iiJ at an intermediate rotational angle between one fixed position of the shaft and the next fixed position, the arm closes the gate 1ffi path halfway. Stop at the condition,
J of the gate... Over-restriction, inhibition, Lf - does not lose its function.

In the following explanation, the rotation axis of the turnstile is followed by g: the part that controls the passage of people in the aisle (the name of A and the term 1- are used as arms, but this is for convenience) 1 is not intended to be limited to a rod-shaped arm.For example, a plate-shaped body extending from the ceiling to the floor on a rotating shaft, or a U,
It is also possible to connect a plurality of lattice bodies, rectangularly bent tubes, rod-like bodies, etc. in a planar force pair and use them in a revolving door format.
