Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a coaster or the like installed in an amusement park or the like, and when a game vehicle is pulled up along an ascending slope, in the unlikely event that the vehicle attempts to run in reverse, this reverse operation is surely prevented. Regarding anti-running device.

[0002]

2. Description of the Related Art In amusement vehicle facilities such as various types of coasters installed in amusement parks and event venues, amusement vehicles imitating cars, trains, ships, airplanes, etc. are pulled up from a low place to a high place. It is known that this potential energy is used to cause the vehicle to play by gravity by dropping, running or sliding along a track to a low place.

This type of amusement vehicle descends from a high place to a low place by gravity, and on the contrary, when pulling it up from a low place to a high place, a special pulling device is required. As a vehicle lifting device of this kind of climbing grade, a pulling chain or wire is laid on a track of climbing grade and a hook is provided on the vehicle side, and the hook is hooked on the pulling chain or wire etc. There are known ones in which the vehicle is pulled up, and one in which a holding plate projecting from the vehicle is sandwiched by a pair of tires and the vehicle is moved upward by rotation of these tires. In particular, in recent years, coasters are often installed indoors, and in such a case, it is necessary to reduce noise. Therefore, the above-mentioned tire holding method, which is less noisy, is often used as the pulling device.

However, in the case of either the hooking method using the above-mentioned pull-up chain or wire, or the tire-holding method, the hook should come off, the chain or wire should be cut, the tire should be damaged, or the tire should slip. If the pulling force is released for some reason, such as when the game is performed, the amusement vehicle will start traveling in the opposite direction on the ascending slope, which is extremely dangerous.

In order to prevent such problems,
Conventionally, as shown, for example, in Japanese Utility Model Application Laid-Open No. 56-125295, a reverse running prevention device is provided. A conventional reverse running prevention device is, for example, a rack rail along a track of an ascending slope.
The rack is laid, and a rotating pawl that can be locked to the fixed teeth of the rack rail is rotatably mounted on the vehicle side. The rotating pawl is hooked on the fixed teeth of the rack rail to reverse the vehicle. Was supposed to stop. That is, when the vehicle normally pulls up the climbing orbit by the pulling device, the turning pawl turns over the fixed teeth of the rack rail one by one. The rotating claw rotates in one direction when passing over one fixed tooth, and reversely rotates so as to be caught by the tooth at the moment when the tooth is crossed over, so as to be prepared for reverse running. .

[0006]

However, since the conventional reverse-travel preventing device has a structure in which the rotating claw is rotatably attached to the vehicle, the vehicle needs a support mechanism such as a support shaft and a bearing. . In addition, recently, since more intense thrills are required, the speed of the vehicle becomes faster, the movement becomes more vigorous, and the vibration and impact of the vehicle are also increasing. Therefore, as a safety measure, the rotating claw is required to have high mechanical strength and high reliability, and it is inevitably made large in size such as being thickened to increase rigidity. In order to attach such a large rotating pawl to a vehicle, a supporting mechanism such as a support shaft and a bearing must be upsized, which increases the weight of the vehicle and requires a large space at the bottom of the vehicle.

In addition, when a large turning claw is provided on the vehicle side, a vibration sound is generated each time the turning claw rotates during a climbing gradient, and the vehicle flips over during a track other than the climbing gradient.
When twisting or jumping into the surface of the water, undesired gravity or a severe impact is applied to the rotating claws, causing them to rotate or vibrate, causing vibration or collision noise, and early wear or damage. There is a concern.

The present invention has been made in view of the above circumstances. An object of the present invention is to make a pawl provided on a vehicle side fixed so that the space occupied by the fixed pawl is small.
An object of the present invention is to provide a reverse running preventing device for a track running vehicle which can reduce the weight of the vehicle, does not generate unpleasant vibration and noise, and has high reliability for safety.

[0009]

According to the present invention, there is provided a vehicle which travels along a track, a pulling device which is provided at an ascending slope of the track and which pulls up the vehicle, a fixed claw fixed to the vehicle, The fixed claws are installed along the passage of the fixed claws at a predetermined interval on the ascending slope of the track, and when the fixed claws move upward, the fixed claws are pushed and rotated to pass the fixed claws. And a rotation pawl that returns to the rotation when the fixed pawl passes and prevents the fixed pawl from returning backward.

[0010]

According to the present invention, when the vehicle starts to fall backward due to the climbing gradient, the fixed pawl is caught by the rotary pawl, and the rotary pawl prevents the fixed pawl from returning. Can be stopped. In this case, the fixed pawl provided on the vehicle side has a fixed structure that does not rotate, and conversely, the pawl on the track side is made rotatable, so that even if the fixed pawl on the vehicle side is enlarged, the support shaft and bearing are not required. A special space is not required and the weight burden on the vehicle side is small, so that the fixing claw can be increased to increase the mechanical strength. In addition, since the rotating claws provided on the track side of the climbing slope rotate, there is no rotating member other than the climbing slope, and there is no fear of generating unpleasant vibration or noise even in a region other than the climbing slope.

[0011]

FIG. 10 is a side view schematically showing the overall structure of a track 1 for guiding a game vehicle. The track 1 is composed of a pair of left and right rails 2 and 2, which will be described later, and has an ascending slope and a descending slope. Although not shown in detail, it has a loop orbit, a twist orbit, and in some cases, an endless orbit through a waterway. A game vehicle, for example, a vehicle (hereinafter, referred to as a vehicle) 3 having a vehicle shape runs along the track 1. Although the vehicle 3 may have a well-known structure, detailed description thereof will be omitted. However, the vehicle 3 is provided with a passenger seating portion such as a seat or a standing seat, and the passengers riding this seating portion ensure safety. The body is held by a body holder such as a belt (not shown). A platform 4 is provided in a portion of the track 1 near the ground. The rails 2 and 2 are supported by a frame 5, as shown in FIG. The frame 5 is supported by a large number of building columns 6 ... As shown in FIG.

Trajectories 1 are provided on the left and right sides of the frame 5, respectively.
As shown in FIG. 7, columns 7, 7 are provided upright along the rails, and the rails 2, 2 are fixed to the upper ends of the columns 7, 7.

The pair of left and right traveling rails 2 and 2 are shown in FIG.
As shown in, it is formed of a pipe, for example. The vehicle 3 is provided with wheels at, for example, four corners in the front, rear, left and right. As shown in FIG. 7, these wheels have rolling wheels 2 a and 8 b that roll along the upper and lower surfaces of the traveling rails 2 and 2, and lower wheels 8 a and 8 b and side wheels 8 c that roll along the side surfaces of the traveling rails 2 and 2. is doing. Therefore, the vehicle 3 rolls on the upper and lower traveling wheels 8a and 8b and the side wheels 8c so as to surround the traveling rails 2 and 2, so that the vehicle 3 can travel along the track 1 without removing the wheels. Has become.

On the climbing slope of the track 1, there is provided a pulling device 10 for pulling the vehicle 3 from a low place to a summit. The pulling device 10 will be described. As shown in FIGS. 7 to 9, a holding plate 11 is fixed to the bottom of the vehicle 3 at a substantially central position. Holding plate 11
Extends in the front-rear direction of the vehicle 2 and is held by the pair of left and right tires 12a, ... That is, a pair of left and right tires 12a and 12b are arranged on the climbing slope at intervals in the climbing direction, and these tires 12a and 12b are respectively hydraulic motors 13a and 13b.
It is designed to be driven to rotate by. In this case, the holding plate 11 is sandwiched between the left and right tires 12a and 12b, and the tires 12a and 12b rotate in mutually opposite directions to push the holding plate 11 forward. The hydraulic motors 13a and 13b are connected to the hydraulic pipe 14
The hydraulic oil is supplied through ... And this hydraulic oil is supplied from the hydraulic pump 15 shown in FIG.

Therefore, when the vehicle 3 that has left the platform 4 reaches the climbing gradient of the track 1, the holding plate 11 of the vehicle enters between the left and right tires 12a and 12b, and the holding plate 11 is rotated by the rotation of these tires 12a and 12b. Is pushed out, the vehicle 3 is pulled up the ascending slope.

A reverse running prevention device 20 is installed on the climbing slope. The reverse running prevention device 20 will be described. Fixed claws 21, 21 are fixed to the bottom of the vehicle 3 at the left and right. The fixing claws 21, 21 may be fixed to the vehicle 3 by welding or the like, or may be fixed to the vehicle 3 by using auxiliary fixing members 22 ..., In short, they are immovably attached to the vehicle 3.

Corresponding to the fixed claws 21 and 21, the guide grooves 23 and 2 are located at the left and right in the ascending slope of the track 1.
3 is formed. These guide grooves 23, 23 are guide plates 24 which are provided to face each other at a distance from each other.
Are formed by ... and these guide plates 24 ...
Extends along the ascending slope of the track 1, and the fixed claws 21, 21 on the vehicle side pass through the guide grooves 23, 23 formed between them. The guide plates 24 are supported by the frame 5, the construction columns 6 and the columns 7 and 7 by brackets 25.

Since the guide grooves 23, 23, which are separated from each other in the left and right direction, are symmetrical, only one of them will be described. However, between the pair of guide plates 24, 24, a large number of rotating claws 26 are arranged along the climbing slope. They are attached at equal intervals. These rotating claws 26 are rotatably supported by a pair of guide plates 24 and a support shaft 27 that is stretched between them. As shown in FIG. 6, on the support shaft 27, bushes 28a, 28b made of synthetic resin are provided with bush receivers 29a, 29b.
Is supported via the bushing 2.
It is rotatably supported by 8a and 28b.

A double torsion spring 30 is wound around the support shaft 27 as a rotation return member. The double torsion spring 30 has a pair of coil portions, and a central portion 30a is connected between these coil portions.
0a is in contact with the front surface side of the rotating claw 26, so that the rotating claw 26 is biased counterclockwise in FIGS. 1 and 2. Both ends 30b of the double torsion spring 30 are locked to the hook shaft 31. As shown in FIG. 4, the spacer 3 is attached to the hook shaft 31.
2 and a rubber collar 33 are provided.

The rotating claw 26 is urged to rotate counterclockwise by the spring 30, but is stopped by colliding with a stopper provided above the support shaft 27. That is, the guide plates 24, 24 located on the left and right
As shown in FIG. 5, each of the stopper pins 3
5, 35 are attached to the stopper pins 35,
The inner end of 35 extends into the guide groove 23. Buffer members 36, 36 made of an elastic material such as natural rubber, synthetic rubber, or synthetic resin are attached to the inner ends of the stopper pins 35, 35. On the other hand, the stopper pins 35,
The recessed collision surface 3 with which the tip end of 35 abuts freely and separably
7, 37 are formed. When the rotating claw 26 is rotated counterclockwise by the urging force of the double torsion spring 30, the recessed collision surfaces 37, 37 cause the stopper pin 3 to move.
The tip ends of the reference numerals 5 and 35 are hit, and the turning claw 26 is stopped by this. The shock and sound caused by the collision at this time are absorbed by the cushioning members 36, 36.

The turning claws 26 are provided such that their tip ends face the movement path of the fixed claw 21 provided on the vehicle 3 side, and the vehicle 3 is raised by the pulling device 10. At this time, the fixed claws 21 are also integrally moved upward, and by this movement, the rotary claws 26 are pushed by the fixed claws 21 from the rear surface, so that as shown in FIG. It is designed to rotate clockwise against the force. Then, when the fixed pawl 21 passes by this rotation, the force of the spring 30 causes it to return counterclockwise and hit the stopper pins 35, 35 to stop.

A cushioning member 38 made of an elastic material such as natural rubber, synthetic rubber or synthetic resin is adhered to the rear surface of the rotating claw 21 against which the fixed claw 21 on the vehicle side abuts. By doing so, the sound and impact when the fixed claw 21 hits is absorbed.

The operation of the embodiment having such a configuration will be described. When the vehicle 3 exits the platform 4 of the track 1 and reaches the ascending slope, the holding plate 11 protruding at the center of the bottom surface of the vehicle enters between the left and right tires 12a and 12b, and at the same time, is fixed so as to project to the left and right of the bottom of the vehicle. The claws 21, 21 enter into the guide grooves 23, 23 of the reverse run prevention device 20. The holding plate 11 is pushed out by the rotation of the tires 12a and 12b, so that the vehicle 3 is raised in the climbing gradient of the track 1.

In this process, the fixed claws 21 provided on the vehicle 3,
21 passes over the rotating claws 26, 26, ... Installed in the guide grooves 23, 23, respectively. That is, as the vehicle 3 moves forward, the fixed claw 21 also moves forward integrally, and this movement causes the fixed claw 21 to push the rear surface of the tip of the rotating claw 26. Therefore, as shown in FIG. 2, the rotating claws 26 are rotated clockwise about the support shaft 27 and against the torsion spring 30,
Therefore, the fixed claw 21 passes over the rotating claws 26 ... When the fixed claws 21 pass by, the rotary claws 26 ... Return to the counterclockwise rotation by receiving the biasing force of the spring 30, and the stopper pin 3
It stops at 5, 35.

When the pulling device 10 is operating normally, the fixed claw 21 pushes over the successive rotating claws 26, ... If, for example, the vehicle 3 tries to lower the climbing slope in the opposite direction by any reason, such as a tire being damaged, slipping, or a hydraulic system failure, the vehicle 3 will collide with the vehicle 3 side. Fixed claw 2 installed
As shown in FIG. 1, 1 corresponds to the front surface of the rotating claw 26. For this reason, the rotating claw 26 tries to rotate counterclockwise, but the rotation is blocked because it abuts on the stopper pins 35, 35, so that the fixed claw 21 is stopped in a state of hitting the rotating claw 26. . That is, in the vehicle 3, the fixed claw 21 has the rotating claw 2
By hitting the front of 6 and being stopped, reverse running is prevented. Therefore, safety is maintained.

In the case of the reverse running prevention device 20 of the above-described embodiment, since the pawl provided on the vehicle 3 side is the fixed pawl 21, a support mechanism such as a special support shaft or bearing is not required on the vehicle side. Yes, no special space is required on the vehicle side. For this reason, it is possible to increase the size of the fixing claw 21 such as making it thicker, thereby increasing the mechanical strength.
As a result, as in recent years, when a more intense thrill is required, the speed of the vehicle becomes faster and the movement becomes violent, and when there is a tendency that a large vibration or shock is applied to the vehicle, as a safety measure, Since the mechanical strength of the fixed claw 21 can be increased, high reliability can be obtained.

Moreover, since the fixed claw 21 is literally a fixed type, there is no fear of turning or shaking when the vehicle 3 travels on a track other than an uphill grade, and therefore vibrations or vibrations occur in areas other than the uphill grade. It is possible to prevent the impact and the generation of noise accompanying it.

Further, in the above embodiment, since the cushioning material 38 made of an elastic material such as natural rubber, synthetic rubber, or synthetic resin is adhered to the back surface of the rotating claw 21, the fixed claw 21 comes into contact. In this case, sound and shock can be absorbed, which is effective in reducing noise and wear due to shock and vibration can be reduced, so that the life is extended.

Further, since the cushioning members 36, 36 made of an elastic material such as natural rubber, synthetic rubber, or synthetic resin are attached to the ends of the stopper pins 35, 35, the turning claw 26 is doubled. When the dented collision surfaces 37, 37 come into contact with each other due to the urging force of the torsion spring 30 and come into contact with each other, the shock and noise due to the collision are absorbed by the cushioning members 36, 37.
Absorption by 36, thus preventing noise and damage.

Particularly in terms of noise, since the pulling device 10 of this embodiment has a structure using the tires 12a and 12b, the pulling device 10 is originally low in noise, and in addition to this, the reverse running preventing device 20 is not provided. Since it reduces noise, it is advantageous when applied to indoor type coasters and the like.

Further, in the reverse running prevention device 20 of the present embodiment, the left and right fixed claws 21, 21 are provided with the left and right guide grooves 23, respectively.
Since the turning claws 26, 26 installed on the block 23 prevent the reverse crawling, even if each function is lost in the fixed claw 21 or the guide groove 23 of one row, the other row works to prevent reverse running. , High safety.

Similarly, a double torsion spring 30 is used as a spring for urging the rotation of the rotating claw 26, and a central portion 31a thereof is used.
Since one of the coil portions is damaged and the other coil portion is actuated, the rotating claw 26 is urged to rotate, so that safety is secured also in this respect. The present invention is not limited to the above embodiment. That is, in the above embodiment, one fixed claw is arranged on each of the left and right sides, but the present invention is not limited to this, and either one of the left and right may be provided.

If the fixed claws 21 are provided one for each row, in the unlikely event that the vehicle 3 starts reverse running, the maximum distance of this reverse run is the pitch p in the front-rear direction of the rotary claws 26. If the pitch p of the rotating claws 26 is set to be large in the front-rear direction, the reverse running distance becomes long and the impact when the stationary claw 21 collides with the passing rotating claws 26 and stops is large. Become. In order to prevent this, it is necessary to set the front-rear direction pitch p of the rotating claws 26 to a small value, but in this case, the rotating claws 26 to be provided over the entire ascending slope of a predetermined distance.
Will be installed in large numbers. Therefore, another embodiment as shown in FIG. 11 is effective. That is, in this embodiment, a plurality of, for example, two 201, 202 fixed claws fixed to the vehicle 3 side are installed along the traveling direction of the vehicle. In this case, the mounting pitch L of the fixed claws 201 and 202 located at the front and rear is p / 2, 3P / 2, 5P / 2, etc. with respect to the pitch p of the rotary claws 26 provided on the track side. Dimensional relationship, that is, L = p (n + 1/2), where n is an integer including 0. In the case of this embodiment,
Two fixed claws 201 and 202 installed apart from each other in the front and rear
The separation distance L is regulated to be 1.5p.

In the case of such a structure, when one fixed claw 201 passes over a certain rotating claw 26, the other fixed claw 202 has already passed over the other rotating claw 26 and has a pitch p.
Since the one fixed claw 201 is disengaged from the rotary claw 26 and the vehicle 3 runs in the reverse direction, the other fixed claw 202 is moved to the pitch p.
When the vehicle moves backward to the half position, the reverse claw 26 is stopped by engaging with the rearward turning claw 26. That is, the reverse running distance is half of the pitch p of the rotating claws 26, and therefore the reverse running distance is shortened, so that the impact is reduced. Even if one of the fixed claws 201 or 202 is damaged, the other fixed claw 202 or 201 can prevent the reverse running.

Further, for example, when three fixed claws fixed to the vehicle 3 side are installed along the traveling direction of the vehicle, the mounting pitch L of these fixed claws is set with respect to the pitch p of the rotating claws 26. L = p (n + m / 3) However, if n is an integer including 0 and m is an integer of 1 or 2, the reverse distance can be shortened in the same manner as above, and The impact of can be reduced.

On the contrary, when the fixed claws 201 and 202 are set to the pitch L, the pitch of the rotary claws 26 can be set to L or more. In this case, the rotary claws 26 installed on the ascending slope.
You can also reduce the number of. The present invention also relates to the vehicle 3
The pulling-up device for pulling up the climbing slope is not limited to the tire-holding type, but may be a winding type using a chain or wire. Further, the reverse running prevention device is not limited to having the pair of left and right fixed claws 21, 21 and the pair of rows of guide grooves 23, 23, and may be provided in any one row.

Further, the restoring force of the rotating claws 26 is not limited to the urging force of the double torsion spring 30, but another spring or the like may be used, and gravity is utilized by appropriately selecting the position of the center of gravity. Alternatively, the rotating claw may be automatically returned.

Further, the vehicle may be boat-shaped, and such a boat-shaped vehicle can be made to slide down from a high place and land in a waterway, in which case the fixed pawl does not splash the water spray violently. It is preferable that the cross section has a streamlined shape or a similar shape.

[0040]

As described above, according to the present invention, when the vehicle normally moves up and forwards, the fixed claw fixed to the vehicle side sequentially pushes down the rotating claws provided on the track side to get over the vehicle. And if the vehicle starts to fall back,
Since the fixed claw is caught by the rotating claw to prevent the vehicle from returning, it is possible to prevent the vehicle from running backward. In this case, the fixed claw provided on the vehicle side has a fixed structure that does not rotate, and conversely, the track side claw is made rotatable, so even if the fixed claw on the vehicle side is enlarged, the support shaft and bearing are not attached to the vehicle side. Since it is unnecessary, the weight load on the vehicle side is small, and a large space is not required, the fixing claw can be enlarged to increase the mechanical strength. Therefore, the reliability of safety becomes high. Further, since the rotating claws provided on the track side of the climbing slope are rotated, there is no fear of generating unpleasant vibration or noise in a region other than the climbing slope.
