Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a passenger restraint device installed in the passenger seats of an amusement facility installed in an amusement park or the like. Special K relates to a passenger restraint system equipped with a track running vehicle VC that performs somersaults, twists, etc. while running.

[Conventional technology]

As a prior art related to the present invention, Japanese Patent Application Laid-Open No. 51-100
531, Utility Model Publication No. 56-124490, etc.

All of these have a U-shaped arm that is pivotally attached to the headrest at the rear of the vehicle seat.

The U-shaped arm is rotatable in a direction in which a passenger in the seat is restrained and in a direction opposite to the direction in which the passenger is moved away from the seat, and the U-shaped arm has a piston rod connected to an end of a lever protruding from the pivot portion. A check valve is provided in the middle of the hydraulic circuit of the hydraulic cylinder, and by restricting the flow of oil in only one direction, the arm moves only toward the seat when restraining the passenger, and the passenger does not move from the seat. When entering and exiting, the structure is such that the user moves only in the direction away from the seat.

[Problem that the invention seeks to solve]

Such conventional technology has three major problems.

The first is that the center of rotation of the U-shaped arm, which is pivotally connected to the headrest portion at the rear of the seat, is fixed.

Originally, the purpose of these amusement facilities was for passengers of various sizes to ride safely and enjoyably, but the above-mentioned U-shaped arm passenger restraint system allows passengers to adjust their body shape to suit their body shape. There was no guarantee that he could be restrained.

Second, the shape of the arm is U-shaped when viewed from the front.

Since it is merely L-shaped in side view, it is not sufficient to restrain the passenger from the side. Moreover, when considered together with the first problem mentioned above, the negative effects are further amplified.

For this reason, in the prior art, the seat section is made concave and shaped like a packet with convex portions on the sides to overcome the above-mentioned problems.

Third, although the prior art uses a hydraulic cylinder as a locking means to control the rotation of the U-shaped arm, the reliability of this mechanism cannot be said to be sufficient, and as in the amusement facilities of the present application and the prior art, In vehicles where the vehicle travels at high speed and performs waves, curves, somersaults, etc., the safety of passengers' bodies is particularly important.

[Purpose of the invention]

The present invention solves the problems of the prior art as mentioned above, that is, the first K.
The present invention aims to provide a passenger body restraint device that employs a mechanism that is adapted to the physique of the passenger to the maximum extent possible and the shape of a single passenger valve body restraining arm, and that functions quickly in order to improve business efficiency. Second, there is provided an invention relating to the movement and shape of the passenger body restraining arm so that the passenger of the rapidly moving vehicle can hold the passenger's chest and sides so that the passenger does not fall off the passenger body restraining arm. try to. Thirdly, it is an object of the present invention to provide a device (d) in which a body restraining arm can be easily lifted when a vehicle is in a platform area, and the lifted arm does not come down due to its own weight.

[Means for Solving the Problems] The first means used by the present invention to solve the problems mentioned above is to change the support method and movement of the passenger body restraining arm. That is, the rotation center shaft portion of the passenger body restraining arm is not a bearing fixed to the vehicle body or an accessory to the vehicle body, but the passenger body restraining arm is fixed to an arm fixing link which is one side of the link mechanism, By swinging the swinging link connected to the arm fixed link about a shaft that is pivotally supported by a part of the passenger seat where passengers are seated.

The movement of the passenger restraining arm is different from the conventional movement, and the restraining means is adapted to the physique of the passenger.

The link mechanism includes the arm fixed link, the swing link, a link fixed to the vehicle body, and a member that limits movement of the arm fixed link.

Second, the shape of the passenger restraining arm is completely new. A pair of left and right passenger body restraining arms were fixedly attached to the arm fixing link and rolled in a curved manner, and the distal ends of the arms were slightly rolled inward to form a curved shape in the lateral direction of the passenger.

This makes it possible to prevent the passenger from falling off the passenger's shoulder in an upward direction, forward direction, and sideways direction.

Thirdly, a forward/reverse ratchet mechanism for locking or unlocking the central axis of swing of the swing link is adopted as the mechanism for locking or unlocking the movement of the passenger body restraining arm. However, the locking method is not limited to the ratchet method, and may be a combination of a pinion and a rack gear, which restricts the movement of the tin rocket interlocked with the rotation of the passenger restraining arm and the chain engaged with the sprocket. No matter the method.

[For production]

The passenger restraint device for an amusement ride having the above structure does not fix the fulcrum of the arm restraining the passenger's body, but controls the movement of the arm fixed link connected to the swinging link by using another member, for example, another link. Alternatively, the body restraining arm may be adapted to the different physiques of the passengers by restricting it with a guide rail, etc., and the shape of the passenger's body restraining arm may be curved to prevent the passenger from moving upward while the vehicle is running. , prevent it from falling off in the forward and lateral directions.

Furthermore, as a mechanism for locking or unlocking the movement of the passenger restraining arm, we have adopted a forward/reverse ratchet mechanism that locks or unlocks the central axis of swing of the swing link, so when the vehicle is in the platform area, As shown in the following embodiments, it is easy to easily lift the body restraining arm upwards with human power and to create a device that holds the lifted body restraining arm so that it does not come down due to its own weight. It is possible.

[Embodiments of the invention]

The present invention will be described below based on embodiments shown in the drawings.

FIG. 1 shows a situation where a torsion vehicle equipped with the first embodiment of the passenger restraint system of the present invention has just loaded passengers on the platform, and the passengers in the first row are always aware that the vehicle is running. The arm of the passenger restraint system is down so we can start. The passenger in the second row was in the process of having his arm lowered.

The third row passenger's arm is still up, and they are about to have it lowered. 1 is the vehicle, 2 is the rail,

FIG. 3 is a side view of the mechanical part of the 1N passenger restraint system 60, with most of the arm 70 and the horizontal member 8 being omitted. 9
is the rear bone of the passenger, and 10 is a bracket.

The bracket 10 is partially plate-shaped and stands perpendicularly to the upper plate of the rear bone 9 of the passenger.
and are integrally attached with bolts, etc. 11 is the main rotation center axis, which is one of the four-bar mechanisms that move in conjunction with the movement of the arm 7.
This is the center axis of the swing of the two links, as well as the center axis of the rotation or support of the ratchet wheel and its related parts, which will be explained in detail later.

Reference numeral 12 denotes a rotation center axis of a link other than the 11 link of the four-section mechanism, and both the main rotation center shaft 11 and the rotation center shaft 12 are supported by the bracket 10 via bearings. . That is, the position of the center line of the main rotation center shaft 11 and the center line of the rotation center shaft 12 are both fixed to the vehicle body. Reference numeral 13 denotes a swinging link, which is fixed to the main pivot axis 11 with a key. 14 is also a link and is fixed to the one-turn center shaft 12 with a key. Among the links of the four-bar mechanism, reference numeral 15 is an arm fixed link that is integrally attached to the arm 7 and fixed to the mounting plate at the base of the arm 7 with bolts, and is the longest link of the four-bar mechanism. . In order to determine the length of the link as a four-bar mechanism, the movement of the arm 7 and the horizontal member 8 integrated with it is determined by
It is necessary to provide appropriate movement to support the body of the passenger. As one example, the distance between the main rotation center axis 11 and the rotation center axis 12 is 85 m, and the swinging link 1302 is used.
90 mm between the two rotation center axes, 90 mm for the link 14
m5+, the arm fixed link 15 has a rotation center axis of 110
It was dark. When determining these dimensions, (1) the arm 7 should be high enough to avoid hitting the passenger's head when the passenger gets on and off the platform;
2) The movement from when the passenger takes the seat to when the passenger is held down must be appropriate.

(3) Adaptability to passenger size. The main goal is to For relatively small passengers, the tip of the arm 7 and the transverse member 8 are suitable for holding back relatively large passengers.
I tried to hold it down below the loaf. Arm fixation/ri 15
However, when changing the inclination in the direction of lowering arm 7,
The length of each link is determined so that the position of the arm fixing link 15 makes a considerable downward movement where the arm 7 approaches the passenger's body. Reference numeral 16 indicates a rotation center axis between the link 14 and the arm fixed link 15.

Reference numeral 17 indicates a rotation center axis of the swinging link 13 and the arm fixed link 15. 18 is a bracket, 19 is a fixed tube,

The effects of 18.19 and 20.21 will be explained later.

FIG. 4 is a perspective view of FIG. 3. A cross-section is shown for convenience in understanding the connection relationships between each axis and each link.

Among the ratchet wheels, 22 is a ratchet wheel that works to prevent the arm 7 from rising when holding a passenger while traveling, and 23 is a ratchet wheel that works when a passenger stands up on the platform to get on or off the platform. , are ratchet wheels that function to support the arm 7 upward, and 24 is a ratchet wheel 22 and 2.
The ratchet wheels 22 and 23 and the spacer plate 24 are spacer plates that maintain the distance between the ratchet wheels 22 and 23 and the spacer plate 24.

A key is secured to the main rotation center shaft 11. 25 is a ratchet pawl that engages with the ratchet wheel 22, and only one of the two pawls is shown in FIG. 26 is the fourth
Although not shown in the figure (shown in FIG. 6), there is only one ratchet pawl that engages with the ratchet wheel 23, and will be explained later. 27 is the shaft of the ratchet pawl 25, which is locked with a key. axis 2

A fixed cylinder 19 attached to a bracket 18 fixed as one unit.
It is also supported by the center pin 21 of the rubber elastic body 20 inside the cylinder.

Between the frame 29 and the frame 30, there are two shafts 27 and two shafts 28.
One of them passes through a ball bearing. 31
．． 32 (represented in FIGS. 3 and 6) is a driven lever, 33 is a spring lever, and both the driven levers 31, 32 and spring lever 33 are keyed to the shaft 27 or 28. 34 is a roller frame, 35 is a stop roller, 36 is a cam roller, and 37 (not shown in FIG. 4, but shown in FIG. 6) is a spring. The roller mount 34 rotates within the notch C of the mount 30 around the main rotation center axis 11 within a range in which the stop roller 35 can swing.

When the roller mount 34 rotates, the three cam rollers 3
6 moves in an arc to push the driven levers 31 and 32 up against the tension of the spring 37, or to push them down by the tension of the spring 37. 38
is a control cable that rotates the roller mount 34 against the tensile force of the tension spring 37 for rotating the roller mount 34.

Figure 5 shows the ratchet wheel 22 and ratchet pawl 25.
．． 26 and driven lever 31.32 and cam rollers 36 and 4
In order to make it easier to understand the relationship between the links 13, 14, 15 of the cylinder mechanism and the arm 7, this is a side view of a model. The imaginary line shows the stomach at arm 70 when arm 7 went up and when it started going down.

FIG. 6 is a perspective view of the ratchet wheels 22 and 23 of the passenger restraint system of this embodiment and parts near them, drawn for ease of understanding.

This is a view of parts near the ratchet viewed from above and diagonally behind the audience seats. Ball bearings, etc. are omitted. Since FIG. 4 is a view seen from the front, the arrangement of parts on the drawings in FIG. 6 and FIG. 4 appears to be different from right to left. ,3
A spring 9 pulls the end pin of the spring lever 33, thereby pressing the end of the ratchet pawl 25 toward the teeth of the ratchet wheel.

Since the passenger restraint device of the above embodiment has the above-mentioned structure,
When the body of a passenger sitting on the seat is restrained by the arm 7, the ratchet pawl 25 engages with the teeth of the ratchet wheel 22 and does not go up with the arm 7.

Due to the tensile force of the spring 39 of the spring lever 33, the shaft 27 keeps the ratchet pawl 25 in contact with the teeth of the ratchet wheel 22. At this time, the cam roller 36 pushes up the driven lever 32 by the force of the spring 37, and the ratchet pawl 2
6 is separated from the teeth of the ratchet wheel 23.

When the vehicle enters the platform area, the control cable 38 is pulled down by the sled-shaped guide plate, and the roller mount 34 moves within the range in which the stop roller 35 can move within the cutout C of the mount (B). The cam roller 36 moves with the rotation of the roller mount 34 to push up the tip of the driven lever 31 and stop pushing up the tip of the driven lever 32. As a result, the tip i of the ratchet pawl 25 separates from the ratchet wheel 22, and the tensile force of the spring 39 causes the tip i of the ratchet pawl 25 to move away from the ratchet wheel 22.
The tip of the arm 7 is in contact with the ratchet wheel 22 so that a person can lift the arm 7 and the arm 7 that has been raised by a person can
This makes it possible for the signal to remain at a high position 1a. When the downward pull of the hunt roll cable 38 was stopped, the roller mount 34 was rotated by the attached spring 37, and the cam roller 36 was moved, pushing up the tip of the driven lever 32 and pushing up the driven lever 31. Then, due to the tensile force of the spring 39 of the spring lever 33, the tip of the ratchet 26 also separates from the ratchet wheel 22, and the tip of the ratchet 25 comes into contact with the ratchet wheel 22.

Since there are two ratchet pawls 25, the arm 7 can be kept closer to the passenger's body buttons than in the case of one ratchet pawl.The outer surfaces of the arm 7 and the horizontal bar are made of spongy elastic material. Since it is covered with a rubber band, this elastic body also improves the close contact with the passenger's body.

The movement of the arm 7 is close to restraining the passenger, and when the arm is moved in the direction of restraining the passenger's body, it approaches the passenger's body and moves significantly downward, so it is suitable for large or small passengers. It can be suppressed.

The distal end G of the arm 7 has a smooth arcuate three-dimensional curved shape that is slightly inwardly wound and opened laterally, so that a portion of the passenger can be comfortably restrained.

FIG. 7 shows a second embodiment of the present invention, in which reference numeral 40 indicates an arm fixed link, 41 indicates a bottle fixed to the arm fixed link 40, and 4
2 is a float fitted around the outer periphery of the bottle 41, 43 is a groove that guides the roller 42, and 44 is! #43, and the member 43 is integrally fixed to the bracket 10. It should be noted that FIG. 7 is similar to FIG. 5 in the first embodiment, and is a side view of the model's snout with its upper legs hidden in order to make it easier to understand the relationship between the parts.

The ratchet wheel 22, the ratchet pawls 25, 26, the driven levers 31, 32, the cam roller 36, the swinging link 13, the arm 7, and the horizontal member 8 integrated with the arm 7 are the same as those shown in FIG. 5 in the first embodiment. be.

FIGS. 8 and 9 show a third embodiment of the present invention, and FIG.
The figures are similar to Figure 5 in the first embodiment, but are modeled from the side to make it easier to understand the relationship between parts, and Figure 9 is similar to Figure 6 in the first embodiment. As for the ratchet wheels 22 and 23 and the parts near them,
This is a perspective view drawn to make it easier to understand, and is a view of parts near the ratchet from diagonally above and behind the audience seats.

8 and 9, reference numeral 50 denotes a frame (2) that pivotally supports a driven lever (described later), a ratchet pawl 25.26, and a shaft 27.28 to which the suspension ring lever 33 is attached; It is an alternative to the trestle). 51.
52 is a driven lever, 53 is a tail projection of the driven lever 51, and the driven lever 51 moves in the same manner as the driven lever 31 in the same position in FIGS. 5 and 6, but the driven lever 52 is different from FIGS. 5 and 6, when the driven lever 510 is pushed by the tail projection 53, it resists the tensile force of the spring 39 (represented on the right side of FIG. 9). The shaft 28 is rotated once, and the ratchet pawl 26 is separated from the ratchet wheel 23. That is, the ratchet pawls 25 and 26 contact the ratchet wheels 22 and 23 at the same time, and leave the ratchet wheels 22 and 23 at the same time.

In FIG. 9, 54 is a roller mount, and 55 is a stop roller, and the roller mount 54 rotates around the main rotating shaft 11 within the range allowed by the notch E of the roller mount 54 and the stop roller 55. . In the configuration shown in FIGS. 8 and 9, the arm 7 can be freely raised or lowered by pulling the control cable 38, but the arm 7 cannot be raised or lowered unless the control cable 38 is pulled. Note that 56 is a gas spring, 57 is a gas spring attachment link, and the gas attachment ring 57 is fixed to the main rotation center shaft with a key. This gas spring 56 and gas spring mounting link 57 are connected when the vehicle is in the platform area and the Bontrol cable 38 is automatically pulled, when the lifted arm 7 is lowered by the weight of the arm 7 itself. This is a part to prevent this from happening.

The present invention is not limited to the above embodiments.

That is, although the position of the wheels of the vehicle or the relationship with the rails is unique in the embodiment, the passenger restraint device of the present invention may be used in a general amusement vehicle. 4 during the explanation of the first embodiment.
Although the actual length dimensions of the links of the cylindrical mechanism have been described, the length dimensions are not limited to these dimensions. The ratchet wheel used was two ratchet wheels with teeth cut in the forward and reverse directions, and ratchet pawls that engaged with the ratchet wheels, respectively, but in order to stop the arm 7,
It does not necessarily have to be a ratchet wheel and a ratchet pawl. As long as a device for hooking the arm 7 can be provided without any problem, it is fine.

Note that in the embodiments of FIGS. 8 and 9, when the control cable 38 (represented in FIG. 9) is pulled and the winter melon 25.26 is away from the ratchet wheel 22.23, the arm 7 (Represented in Figure 8)

In addition, after the content of this application is published, it will be easily possible for a skilled technician in this field to change the configuration to use a balance weight to prevent the arm 7 from coming down due to its own weight. .

〔Effect of the invention〕

As explained above, the passenger restraint device for an amusement ride according to the present invention is capable of firmly holding the passenger's body mechanically without relying on hydraulic equipment, and is capable of holding the passenger's body firmly even for large people. It adapts well to people and does not loosen while driving.This allows you to do somersaults and drive with twisting gears without worrying about hydraulic equipment failure. Once entered, the locking force of the body restraining arm is released and the body restraining arm can be pushed upward and raised. By aligning the ratchet pawl at i%', which is one pitch of the wheel's teeth, the position where the arm presses the passenger's body can be precisely determined.The ratchet wheel has teeth cut in the forward and reverse directions. and a device having ratchet pawls that mesh with teeth cut in the forward direction and ratchet pawls that mesh with teeth cut in the opposite direction,
After the vehicle enters the platform, if you push up arm 7,
Arm 7 stops at that position. However, Figures 8 and 9
In the illustrated embodiment, an upper arm holding device is separately provided.
