Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention relates to a lock mechanism for a passenger holding arm in a passenger holding device installed in a passenger seat of a play vehicle installed in an amusement park.

[Conventional technology]

Roller coasters, somersault coasters, twist coasters, etc. installed in amusement parks, etc. require a means to restrain the body of passengers in order to prevent them from being shaken out by the centrifugal force or gravity. .

As a passenger holding device for such a play vehicle, the means described in Japanese Patent Application Laid-Open No. 51-100531 is conventionally known.

This is a U-shaped arm that holds the upper half of the body of the passenger from the shoulder to the abdomen of the passenger seat in a vehicle running on somersault and twist courses. A piston rod of a hydraulic cylinder is connected to the moving base end, and a control valve for opening and closing the hydraulic circuit of the hydraulic cylinder is provided.

In such a passenger holding device, the passenger sitting in the passenger seat pulls down the passenger holding arm by himself and turns it from the shoulder to the abdomen, and when the control valve is operated in this state, the hydraulic circuit of the hydraulic cylinder is cut off. As a result, the flow of hydraulic oil in the hydraulic circuit is disabled, so that the hydraulic cylinder is unable to expand and contract, which locks the passenger holding arm because it cannot rotate, and thus the passenger holding arm holds the passenger's body. It keeps the state.

The control valve is designed to be centrally operated by an operator, and when the operator operates it to release the hydraulic circuit of the hydraulic cylinder when the vehicle is placed horizontally on the platform, the upper chamber and the lower chamber of the hydraulic cylinder are controlled. Since each of the oils can freely move in and out, in this case, the passenger can freely rotate the passenger holding arm.

Also, if the operator shuts off the hydraulic circuit of the hydraulic cylinder,
The oil in the upper chamber and the lower chamber of the hydraulic cylinder is oil-locked, so that in this case, the rotation of the passenger holding arm is prevented, that is, the lock is kept.

[Problems to be solved by the device]

In such a conventional passenger holding device, if the hydraulic cylinder or hydraulic circuit is damaged or oil leaks during traveling, the oil lock is released and the holding arm can move freely. There is a concern that the retention function will not work.

In the present invention, even if the hydraulic cylinder or the hydraulic circuit is damaged or oil leaks, the passenger holding arm can still be kept in the locked state, and the passenger holding device for amusement vehicle is improved in safety. It is what

[Means for Solving the Problems]

In order to achieve the above object, the present invention, in addition to the conventional hydraulic cylinder for locking, includes a lock pin for releasably engaging the passenger holding arm to lock the passenger holding arm, and a solenoid for operating the lock pin. And a power supply circuit means capable of energizing the solenoid mechanism only when the amusement vehicle is horizontally mounted on the platform, and the passenger holding arm is provided with the hydraulic cylinder and the solenoid while the amusement vehicle is running. The feature is that the mechanism and the mechanism are double locked.

[Action]

According to the present invention, since the passenger holding arm is double-locked by the hydraulic cylinder and the solenoid mechanism during traveling, even if the hydraulic cylinder is damaged or malfunctions, the solenoid mechanism can be locked so that it is safe. Sex is secured.

〔Example〕

The present invention will be described below with reference to FIGS. 1 to 5.

In FIGS. 4 and 5, reference numeral 1 is a play vehicle, which is provided with a plurality of rows of seats 2.

Numerals 3 and 3 are rails that form the running track of the vehicle 1, and although not shown, a twisting course, a somersault course, etc. are formed in the middle of this track. Wheels rolling on these rails 3, 3 are attached to the vehicle 1, and these wheels are an upper wheel 4a and a lower wheel respectively provided at four corners of the vehicle body.
It consists of 4b and side wheels 4c.

In the vehicle 1 of this embodiment, as shown in FIGS. 4 and 5, the position of the seat in the vertical posture is lower than the position of the rails 3, 3 and the chest of passengers having an average physique has the rails 3, 3. It is set to be approximately equal to the height of 3. The vehicle 1 turns when traveling on a twisting course, but this turning center O
As shown in FIG. 5, it is an intermediate point between the left and right rails 3, 3 and is set so that the head portion of the passenger sitting on the seat 2 is as close as possible to the turning center O as compared with the foot portion. This prevents the large G from acting on the passenger's head.

A passenger holding device is provided on the backrest 2a of the seat 2.

A detailed description of the passenger holding device will be given with reference to FIGS. 1 to 3.

The backrest 2a of the seat 2 is provided with a pillar-shaped frame 5, and a pivot shaft 7 is rotatably supported by the frame 5 via bearings 6,6. A passenger holding arm 8 is attached to the rotating shaft 7 so as to rotate integrally.

The passenger holding arm 8 has an inverted L shape when viewed from the side as shown in FIGS. 1 and 4, and has a substantially U shape when viewed from the front as shown in FIG. The upper half of the body of the passenger who sits on the seat 2 is held from the shoulder to the abdomen to hold the body, and both ends of the U-shaped portion are connected to the rotating shaft 7.

When the passenger holding arm 8 is rotated counterclockwise in FIG. 1 to a predetermined position, a sensor s for detecting this is provided and controls an electric circuit described later.

A pair of discs 9 and 9 located at the center of the rotary shaft 7 are fixed by means such as welding. Between the discs 9 and 9, the crankpin 10 is eccentric from the rotary shaft 7. Has been bridged.

A piston rod 12 of a lock hydraulic cylinder 11 is rotatably connected to the clamp pin 10.

A cylinder case 13 of the hydraulic cylinder 11 is rotatably attached to the frame 5 via a support shaft 14, and a piston 15 is slidably fitted in the cylinder case 13. Piston rods 12 and 16 are respectively connected to the piston 15 in the up and down directions, one piston rod 12 is rotatably connected to the crank pin 10, and the piston 15 is attached to the other piston rod 16. A spring 17 is attached which always urges the passenger holding arm 8 toward the passenger's body with a very light force in the downward direction.

In the cylinder case 13 of the hydraulic cylinder 11, the upper chamber 18a and the lower chamber 18b partitioned by the piston 15 are connected to hydraulic pipes 19a and 19b, respectively, and these hydraulic pipes 19a and 19b are connected.
The solenoid type switching control valve 20 switches between conduction and interruption.

This switching control valve 20 connects the hydraulic pipes 19a and 19b to each other, that is, the upper chamber 18a and the lower chamber 18b of the hydraulic cylinder 11 when the solenoid is energized.

On the contrary, when the solenoid is not energized, hydraulic piping 19a and 19b
Of the hydraulic cylinder 11 is cut off.
And the hydraulic oil in the lower chamber 18b is locked, and the piston 15 is kept immovable. Therefore, the rotation of the passenger holding arm 8 is prevented.

In addition, when the 21 passenger holding arm 8 is flipped up, it is a ball that fits in a recess (not shown) formed in the other disk 9 to give a feeling of moderation, and is positioned at that position. It is held by a rod 24 which is pushed by the spring 23. However, when the passenger holding arm 8 is pulled down with a predetermined force or more, the ball 21 comes out of the concave portion of the disc 9 to allow the passenger holding arm 8 to rotate.

A bracket 25 is attached to the frame 5, and a solenoid 26 is installed on the bracket 25. On the plunger 27 of the solenoid 26, there is a rotation lever 28 having a substantially L shape.
, One end of which is connected, and the central portion of the rotating lever 28 is rotatably supported by a support pin 29 attached to the bracket 25. A lock pin 30 is connected to the other end of the rotating lever 28. This lock pin
A spring case 30 slidably penetrates a spring case 31 attached to the bracket 25, and a spring 32 housed in the spring case 31 urges the spring case 31 in a direction projecting upward from the spring case 31.

The disk 9 on the one side faces the lock pin 30.
The stopper block 33 is formed by means such as welding, and the stopper block 33 is formed with a receiving recess 34 into which the lock pin 30 can be engaged.

When the passenger holding arm 8 is pulled down, the solenoids 2 are rotated in a state in which the disks 9 and 9 are rotated by a predetermined angle via the rotation shaft 7.
When 6 is actuated, the lock pin 30 projects. As a result, when the passenger holding arm 8 rises, that is, when it is about to be rotated clockwise in FIG. 1, the lock pin 30 comes into contact with the stopper block 33, and the clockwise rotation of the passenger holding arm 8 is blocked. It is like this.

The solenoid 26 attracts the plunger 27 when energized, and retracts the lock pin 30 to the spring case 31 side.

Further, such a solenoid 26 is installed at a position as close as possible to the turning center O, and even if it is separated at most, it is within a circle having a radius from the turning center O to the passenger's head, for example, a radius r of about 60 cm. It is installed in the circle.

Such a solenoid type switching control valve 20 and solenoid
26 can be connected to the power source only when the vehicle 1 is horizontally mounted on the platform in the traveling track.

That is, as shown in FIGS. 4 and 5, in the platform area, the current collecting rail 35 is laid in the track within the length of the platform. The current collecting rail 35 is connected to a power source such as a commercial power source via a main switch in a central control room (not shown). On the other hand, a current collector 36 is attached to the vehicle 1, and the current collector 36 is electrically connected to the solenoid type switching control valve 20 and the solenoid 26.

When the vehicle 1 enters the platform, the contact roller 37 of the current collecting device 36 comes into contact with the current collecting rail 35, so that the solenoid type switching control valve 20 and the solenoid 26 are connected to the power source. Further, when the vehicle 1 is on a track other than the platform, the contact roller 37 of the current collector 36 separates from the current collecting rail 35, so that the solenoid type switching control valve 20 and the solenoid 26 are disconnected from the power source and electrically disconnected. It is configured to be in a state.

The operation of the embodiment having such a configuration will be described.

When the vehicle is on the track platform, the contact roller 37 on the side of the vehicle 1 is in contact with the current collecting rail 37, and therefore the solenoid type switching control valve 20 and the solenoid 26 are electrically connected to each other. In hydraulic piping 19a and 19b
And the upper chamber 18a and the lower chamber 18b of the hydraulic cylinder 11 are electrically connected to each other, the piston 15 can move freely, and therefore the passenger holding arm 8 can freely rotate.

Therefore, the passenger sitting on the seat 2 pulls down the passenger holding arm 8 and surrounds the body so that the passenger holding arm 8 is brought into close contact with the body as shown in FIG.

In this case, the force of the spring 17 causes the passenger holding arm 8
Since it is biased in the pull-down direction, it can be pulled down easily and resists pulling up lightly.

Further, since the amount of rotation of the passenger holding arm 8 is not restricted, a person with a large physique or a small person can hold the body with the passenger holding arm 8.

When all passengers wrap their bodies in the passenger holding arms 8 in this way, the sensor s detects this, and
The main switch in the central control room is automatically turned off, and the solenoid type switching control valve 20 and the solenoid 26 are de-energized.

When the solenoid type switching control valve 20 is de-energized, the solenoid type switching control valve 20 cuts off the connection between the hydraulic pipes 19a and 19b, and the hydraulic cylinder 11
The hydraulic oil in the upper chamber 18a and the lower chamber 18b is locked to disable the movement of the piston 15. The rotation of the passenger holding arm 8 is blocked. As a result, the first stage lock can be achieved.

On the other hand, when the solenoid 26 is not energized, the suction of the plunger 27 is released, and the lock pin 30 receives the biasing force of the spring 32 and projects upward.

Therefore, the lock pin 30 is a stopper block on the disk 9 side.
33, which prevents the passenger holding arm 8 from bouncing up, that is, clockwise rotation in FIG. In other words, the second stage is locked.

In this way, the rotation of the passenger holding arm 8 is blocked in the double lock state, and the vehicle 1 travels on the traveling track.

When the vehicle 1 leaves the platform, the contact roller 37 on the vehicle 1 side is disengaged from the current collecting rail 35, so that both the solenoid type switching control valve 20 and the solenoid 26 are automatically disconnected from the power supply circuit.

If the hydraulic cylinder 11 or the hydraulic pipes 19a and 19b or the solenoid type switching control valve 20 breaks down and hydraulic fluid leaks while the vehicle leaving the platform is running, the lock by the hydraulic cylinder 11 will not work. However, in the case of the above-mentioned embodiment, the lock pin 30 of the solenoid 26 prevents the passenger holding arm 8 from rotating, so that an accident such as the passenger holding arm 8 bouncing up and the passenger being shaken out can be surely and reliably prevented. Can be prevented.

Further, in the case of the above embodiment, since the solenoid 26 is installed at a position as close as possible to the turning center O of the vehicle 1, even if an accident occurs during turning of the vehicle, the centrifugal force applied to the solenoid 26 can be small, It is possible to minimize the dropouts and so on.

In the above embodiment, the plunger 27 of the solenoid 26 is connected to the lock pin 30 via the pivoting lever 28 having a substantially L-shape, but the present invention, as shown as another embodiment in FIG. One end of the straight turning lever 40 may be attracted by the spring 31, the lock pin 30 may be connected to the other end, and the solenoid 26 may be connected to this end side.

Further, in the above-mentioned embodiment, when the passenger holding arm 8 is rotated to hold the body, the sensor s detects this, whereby the main switch of the central control room is automatically turned off, and the solenoid type switching is performed. Although the power supply to the control valve 20 and the solenoid 26 is cut off, the present invention is not limited to this, and an operator may manually switch the main switch of the central control room, or the vehicle may be operated on a platform. When the current collecting rail 35 is separated from the current collecting device 36 by, for example, exiting from the power source, the energization of the solenoid type switching control valve 20 and the solenoid 26 may be automatically cut off.

[Effect of device]

As described above, according to the present invention, since the passenger holding arm is double-locked by the hydraulic cylinder and the solenoid mechanism, even if the hydraulic cylinder is damaged or malfunctions, the solenoid mechanism keeps the lock. Rotation of the passenger holding arm is prevented, and safety is ensured.
