Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a passenger holding device which is provided in a passenger seat of an amusement vehicle installed in an amusement park and safely holds a passenger's body.

[0002]

2. Description of the Related Art Jetcovers installed in amusement parks, etc.
The star, somersault coaster, twisting coaster, or the like requires a means for restraining the body of the passenger to prevent the passenger from swinging out of the vehicle due to 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. In this vehicle, a U-shaped arm covering the upper half of the body of the passenger from the shoulder to the abdomen is rotatably supported by the backrest of the passenger seat in a vehicle running on somersault and twist courses, and the passenger is held. The arm holds the upper body of the passenger. However, in such a rotary arm, since the arm is rotated downward from above, it may not be possible to properly hold the body depending on the physical constitution of the passenger. In other words, the rotating arm that rotates in the vertical direction may cause a gap between the shoulder and the root near the center of rotation of the arm for a person with a short height or sitting height. A person with a high sitting height may hit the shoulder of the arm and hinder the rotation of the arm, and the arm tip may not reach the chest or abdomen and may float.

On the other hand, the applicant of the present invention, the actual development of Sho 55-40
A body holding device as disclosed in Japanese Patent No. 852 has been proposed. This is a pair of arms that open and close to the left and right, and is designed to be pressed from the left and right shoulders of the passenger to the chest. In this case, the passenger can hold the arm with his arm,
Therefore, there is an advantage that the body can be firmly held and the reliability of holding the body is enhanced.

[0004]

However, a structure in which a pair of arms is opened and closed in the left-right direction cannot cope with the height and sitting height difference of passengers, and short passengers have a gap above their shoulders. I have a concern. Also, in the case of this structure, since the arms open to the left and right of the seat, space is required on the left, right, front and back of the seat. Or, it is necessary to reduce the number of seats to narrow the width of the vehicle, and there is a problem that the number of passengers decreases.

The present invention has been made in view of the above circumstances, and an object of the present invention is to securely hold the body even if there is a difference in height among passengers, and to eliminate the need for special spaces in the left-right and front-rear directions. And narrow the vehicle width,
Another object of the present invention is to provide a passenger holding device for a recreational vehicle that can increase the number of seats.

[0006]

In order to achieve the above object, the invention of claim 1 is to press a shoulder portion of a passenger on a play vehicle from above and to connect a pair of left and right shoulders connected to each other by a connecting member. A pressing arm, a guide mechanism for movably guiding the connecting member in the vertical direction, and the connection when the pair of shoulder pressing arms are guided by the guide mechanism and come into contact with the shoulder portion of the passenger. Locking means for locking the member to prevent upward movement of the shoulder pressing arm, releasing means for releasing the locking means, and an urging member for pushing up and urging the connecting member upward. It is characterized by having.

According to a second aspect of the present invention, the lock means is provided on the vehicle, and the rack is formed with a large number of meshing teeth in the vertical direction, and the rack is provided on the connecting member and the meshing teeth are provided on the rack. The engaging claws are engaged with each other, and a plurality of the engaging claws are installed in the vertical direction.
₁ has a size different from the pitch p ₂ of the meshing teeth of the rack.

Further, in the invention of claim 3, the lock releasing means forms the rack with a rod member and forms a large number of meshing teeth along one axial direction on one circumferential side surface of the rod member, By rotating the rack, the meshing teeth are slid from the locking claws to release the lock.

[0009]

According to the invention of claim 1, since a pair of left and right shoulder pressing arms for pressing the shoulders of passengers from above are slid vertically, there is a difference in height and sitting height. Can hold the passenger's shoulder surely from above,
The body can be held securely and safety is ensured. Moreover, since the pair of shoulder pressing arms slide in the vertical direction, no special space is required in the horizontal direction.

According to the invention of claim 2, any one of the plurality of locking claws is one of the meshing teeth formed on the rack.
Since it will be engaged with the other, even if the above-mentioned locking claw should come off or be damaged, other locking claws will engage with the meshing teeth, and the shoulder pressing arm will be It is not released and is highly safe. Further, since the pitch p ₂ of the meshing teeth of the rack and the pitch p ₁ of the locking claws are different from each other, either one of the locking claws will mesh with the meshing tooth at a position close to this, and the meshing The pitch can be reduced.

Further, according to the third aspect of the present invention, since the locking pawl is removed by rotating the rack to change the direction of the meshing teeth in the circumferential direction, the structure of the lock releasing means is simple and the operation is also easy. It's easy.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below based on an embodiment shown in the drawings. FIG. 6 is a side view showing a rail and a playing vehicle which constitute a track of a game traveling vehicle such as a coaster installed in an amusement park or the like. The track is a pair of left and right rails 1, 1 (one side). Although not shown, a twisting course, a somersault course, etc. are formed in the middle.

The vehicle 10 has a seat 12 on a chassis 11.
... is installed. The seats 12 ... have multiple rows in the front and back,
Although not shown in each row, a plurality of seats are formed side by side in the left-right direction. Each seat 12 has a seat portion 13 and a backrest portion 14. In addition, the chassis 11 has
Wheels are mounted on the rails 1, 1 for rolling contact.
The wheels are provided at the four corners of the vehicle body, respectively, and are provided with a main wheel 15, a lifting prevention wheel 16, a side wheel 17 ...

The seat 12 is provided with a passenger holding device 20 according to the present invention. This passenger holding device 20 will be described with reference to FIGS. 1 to 5. Inside the backrest portion 14 of the seat 12, there are a pair of left and right columns 21,2.
1 is provided, and these columns 21 and 21 are erected on the chassis 11. A support plate 23 is attached to the columns 21 and 21 via brackets 22 and a guide rail 24 is fixed to the support plate 23. The guide rail 24 extends in the vertical direction, and has a substantially trapezoidal cross section with a wide front surface.

A pair of shoulder pressing arms 30, 30 are attached to the guide rail 24 so as to be vertically movable. The base ends of the pair of shoulder pressing arms 30 and 30 are fixed to a connecting plate 31, and a slide bush 32 is fixed to the connecting plate 31. A dovetail groove 33 is formed in the slide bush 32, and the dovetail groove 33 is slidably fitted to the guide rail 24 having a substantially trapezoidal cross section. Therefore, the connecting plate 31 can slide up and down along the guide rail 24, so that the pair of shoulder pressing arms 30 and 30 can move up and down along the guide rail 24. Therefore, the guide rail 24, the connecting plate 31, and the slide bush 32 constitute the slide mechanism of the present invention.

The upper ends of the pair of shoulder pressing arms 30, 30 are in contact with the shoulders of passengers, and the distal ends thereof extend obliquely downward and forward. Further, elastic pads 34, 34 such as sponges that come into contact with the shoulders of passengers are provided from the upper ends of the shoulder pressing arms 30, 30 to the distal ends thereof.

A rack 35 constituting a lock mechanism is attached to the one column 21, and, for example, two locking claws 37a and 37b also constituting a lock mechanism are attached to the connecting plate 31. There is. Rack 3
Reference numeral 5 denotes a round bar, and as shown in FIG. 5, a large number of meshing teeth 36 are formed on one side surface in the circumferential direction of the round bar at equal intervals p ₂ along the axial direction. On the other hand, the connecting plate 31 has a pin 38 attached to the holder 38.
The locking claws 37a and 37b are rotatably attached via a and 38b. These locking claws 37a, 37b
Are arranged at intervals of pitch p ₁ along the top and bottom, and are biased by torsion coil springs 39, 39 so as to rotate in the clockwise direction in FIG. In this case, the pitch p ₂ of the meshing teeth 36 of the rack 35 and the pitch p ₁ of the locking claws 37a and 37b on the connecting plate 31 side are different, for example, p ₁ = 2.5p _2. ing.

Therefore, the connecting plate 31 is attached to the guide rail 24.
When it is lowered along with, the locking claw 37 provided on the connecting plate 31
When a and 37b go over the meshing teeth 36 ... Of the rack 35 one by one and descend and stop at any position, either one of the locking claws 37a and 37b meshes with the meshing tooth 36 at a position close to this. . Therefore, the locking claw 37a or 37b
The engagement teeth 36 are engaged to prevent the connecting plate 31 from moving upward, thereby preventing the pair of shoulder pressing arms 30 and 30 from rising.

The upper and lower ends of the rack 35 are rotatably supported by holders 41 and 42 provided on one of the columns 21 about the center axis of the rack. A lock release lever 43 is attached to the lower end of the rack 35. When the lock release lever 43 is turned, the rack 35 turns around the rack center axis. For this reason, the direction of the meshing teeth 36 formed on one side surface of the round bar along the axial direction changes to the circumferential direction, and therefore the meshing teeth 3
6 slides with the locking claws 37a or 37b and escapes in the circumferential direction, so that the meshing teeth 36 and the locking claws 37a.
Alternatively, the engagement with 37b is disengaged. Therefore, the mechanism for rotating the lock release lever 43 and the rack 35 serves as the lock release means.

Although not shown, the lock release lever 43 or the rack 35 is rotationally biased so that the meshing teeth 36 formed on the rack 35 face the locking claws 37a and 37b. For this purpose, a spring or a torsion coil spring is provided, and when the lock release lever 43 is released, the rack 35 automatically rotates and returns. Further, the lock release lever 43 is provided below the seat portion 13 of the seat 12 and can be manually operated by passengers.

One end of a turnbuckle 46 is rotatably connected to the connecting plate 31 via a rotating pin 45. The other end of the turnbuckle 46 is rotatably connected to the tip of a link lever 48 via a universal joint 47. The base end of the link lever 48 is fixed to the flange 49.

The flange 49 is rotatably attached to a support shaft 50 provided on the other column 21. A torsion coil spring 51 is wound around the support shaft 50. One end of the torsion coil spring 51 is locked to the flange 49, and the other end is locked to a hook 52 provided on the support shaft 50. The torsion coil spring 51 biases the flange 49 so as to rotate in the clockwise direction in FIG. Therefore, the link lever 48 is also integrally rotated in the clockwise direction, and the link lever 48 and the turnbuckle 4 are rotated.
6 extends and pushes up the connecting plate 31. That is, the biasing force of the torsion coil spring 51 imparts a force for pushing up the pair of shoulder pressing arms 30, 30.

Reference numeral 53 is a mounting position adjusting hole for mounting the base end of the link lever 48 to the flange 49, and the mounting angle of the link lever 48 with respect to the flange 49 can be selected. The flange 49, the support shaft 50, the torsion coil spring 51, and the like are stored inside the seat portion 13 of the seat 12. And again, the pair of shoulder pressing arms 30, 30 are
As shown in FIG. 6, the seat 12 is led out to the outside from the side surface of the backrest portion 14, so that the backrest portion 14 is formed with a slit 55 that allows the shoulder pressing arm 30 to move up and down.

The operation of the passenger holding device 20 shown in the embodiment having such a structure will be described. When the vehicle 10 is stopped on a platform (not shown), the vehicle 10
The passenger who has boarded the vehicle sits in the seat 12 as shown in FIG. Then, the pair of shoulder pressing arms 30, 30 are pulled down against the biasing force of the torsion coil spring 51, and the elastic pads 34, 34 of these shoulder pressing arms 30, 30 are pulled down until they hit the shoulder.

Then, the pair of shoulder pressing arms 30,
30 and the connecting plate 31 supporting them slide by the guide action of the slide bush 32 and the guide rail 24, and the locking claws 37a and 37b provided on the connecting plate 31 form one meshing tooth 36 ... Of the rack 35. When the elastic pads 34, 34 are overridden one by one and stopped when the elastic pads 34, 34 hit the passenger's shoulder, either one of the locking pawls 37a, 37b engages with the meshing tooth 36 at a position close thereto. Therefore, the engagement plate 37 is prevented from moving upward due to the engagement of the engaging tooth 36 with the locking claw 37a or 37b, and thus the pair of shoulder pressing arms 30 and 30 is prevented from rising.

In this state, the vehicle 10 runs along the rails 1 and 1 and runs on a predetermined course. During this time, seat 1
The passenger sitting at 2 has a pair of shoulder pressing arms 30, 30
Since it is pushed by, the body does not rise. In this case, it is safer to press the lower half of the body such as the knees and waist with a seat belt or other body holding device.

When the vehicle 10 that has traveled on the track in this manner returns to the platform and stops, the passengers receive the seat 14
Rotate the lock release lever 43 under the
Rotates about the rack center axis, the direction of the meshing teeth 36 formed along one axial direction of the round bar along the axial direction changes, so that the meshing tooth 36 is locked by the locking claws 37a or 37b. Comes off. Therefore, the lock is released, and when the pair of shoulder pressing arms 30 and 30 are pushed up, the shoulder pressing arms 30 and 30 are raised and the body holding is released.

The upward movement of the shoulder pressing arms 30, 30 can be automatically or lightly raised by receiving the upward biasing force from the torsion coil spring 51. That is, the torsion coil spring 51 urges the flange 49 to rotate in the clockwise direction in FIG.
Is rotated in the clockwise direction and the link lever 48 and the turnbuckle 46 extend, so that the connecting plate 31 is pushed up.
Therefore, the biasing force of the torsion coil spring 51 is converted into a force for pushing up the pair of shoulder pressing arms 30, 30.
When the biasing force of the torsion coil spring 51 is increased, the pair of shoulder pressing arms 30 and 30 can be automatically pushed up when the lock is released, and when the biasing force of the torsion coil spring 51 is weakened, the lock is released. When released, the force for pushing up the pair of shoulder pressing arms 30, 30 and the own weight of the shoulder pressing arms 30, 30 and the connecting plate 31 are balanced, and the shoulder pressing arms 30, 30 can be raised with a light pushing force. it can.

In the case of the construction of this embodiment, since the pair of shoulder pressing arms 30, 30 are slid up and down, even if the passengers have different heights and sitting heights,
Since the pair of shoulder pressing arms 30, 30 of each seat 12 can be pulled down to arbitrary positions, passengers of different physiques can surely apply the shoulder pressing arms 30, 30 to their shoulders. Therefore, a problem such as a gap above the shoulder is eliminated, and a defect such as floating of the body during traveling can be eliminated.

Moreover, since the shoulder pressing arms 30 and 30 slide up and down, the moving direction of the shoulder pressing arms 30 and 30 is the vertical direction of the vehicle, and it is necessary to secure a special space on the left and right sides of the seat. Absent. Therefore, the space between adjacent seats can be reduced, the vehicle width can be reduced, or the number of seats in the left-right direction can be increased. When the number of seats increases, the operating economy rate improves.

Further, the guide mechanism, the lock mechanism and the lock release mechanism of this embodiment are provided with the backrest portion 15 of the seat 12.
The backrest portion 15 of the seat 12 which is a dead space can be effectively utilized. Further, since the torsion coil spring 51, which requires a three-dimensionally large space, is housed inside the seat portion 14, the space can be effectively used in this respect as well.

In addition, the locking means of the above embodiment is the support 2
The rack 35 provided on the No. 1 and the two locking claws 37a and 37b provided on the connecting plate 31 are formed on the rack 35. One of the two locking claws 37a and 37b is formed on the rack 35. Since it comes to mesh with one of the meshing teeth 36, even if one of the locking claws 37a or 37b is disengaged or damaged, the other locking claw 37b or 37a is meshed with the meshing tooth. Because it engages 36,
The shoulder pressing arms 30 and 30 do not greatly separate from the shoulders, and the safety is high.

The pitch p ₂ of the meshing teeth 36 of the rack 35 and the pitch p ₁ of the engaging claws 37a and 37b on the connecting plate 31 side are made different from each other, for example, p ₁ = 2.5.
Since it is p ₂ , either one of the locking claws 37a, 3a
7b meshes with the meshing teeth 36 at a position close to this. Therefore, the meshing pitch can be reduced, and the meshing accuracy can be increased. On the contrary, the pitch p ₂ of the meshing teeth 36 can be relatively increased and the number of the meshing teeth 36 can be reduced, which facilitates the manufacturing of the rack 35 that requires time and labor for processing. In this case, instead of the relationship of p ₁ = 1.5p ₂ , p ₁ = 0.5
It may be p ₂ or p ₁ = 1.5p ₂ .

Further, a lock release lever 43 is attached to the lower end of the rack 35, and the lock release lever 43 is rotated to rotate the rack 35 about the rack center axis, so that the meshing teeth 36 ... Orient in the circumferential direction. Change the locking claw 3
Since 7a or 37b is removed, the structure of the lock releasing means is simple, a particularly large space is unnecessary, and the operation is easy.

The lock release lever 43 is designed so that passengers can reach and operate it. However, for example, based on the operation of a driver on the platform, the lock release levers 43 of all seats 12 are interlocked. If it is configured to perform the unlocking operation all at once, not only the passenger does not need to perform the bothersome operation, but also the malfunction such as the passenger operating the lock release lever 43 by mischief while traveling can be prevented. .

The present invention is not limited to the configuration of the above embodiment. That is, in the above embodiment, the passenger is supposed to sit on the seat 12, but a standing coaster in which the passenger runs while standing is known, but the present invention can be implemented in such a case.

Further, when the lock is released, the structure for pushing up the pair of shoulder pressing arms 30, 30 and urging them is as follows.
Not limited to using the turnbuckle 46, the link lever 48, the torsion coil spring 51, etc., a tension coil spring or a compression coil spring may be used to pull up or push the connecting plate 31 upward.

[0038]

As described above, according to the present invention, since a pair of left and right shoulder pressing arms are slid vertically to hold the shoulders of passengers from above, there are differences in height and sitting height. However, the shoulders of passengers can be surely pressed from above. Therefore, it is possible to prevent problems such as a gap occurring above the shoulders and floating of the body, and it is possible to reliably hold the body and ensure safety. Moreover, since the pair of shoulder pressing arms is structured to slide in the vertical direction, no special space is required in the left-right and front-rear directions, the space between adjacent seats is reduced, and the width of the vehicle is reduced. The advantage is that the number of seats can be increased. Further, since the plurality of locking claws are provided, any one of the locking claws will be meshed with the meshing teeth of the rack, so that the shoulder pressing arm is not released and the safety is high. In this case, since the pitch p ₂ of the meshing teeth of the rack and the pitch p ₁ of the locking claws are made different from each other, either one of the locking claws will mesh with the meshing tooth at a position close to this. The meshing pitch can be reduced. Further, the lock releasing means has a simple structure and is easy to operate because the locking pawl is removed by rotating the rack to change the direction of the meshing teeth in the circumferential direction.
