Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention is applicable to a track running vehicle device such as a roller coaster installed in an amusement park, etc., when the vehicle is pulled up from a low place on the track to a high place. This invention relates to a device that prevents cars from running in the opposite direction.

[Prior Art] In a track running vehicle device such as a roller coaster installed in an amusement park or the like, when a vehicle is pulled up from a low place on the track to a high place, if the vehicle unexpectedly starts traveling in the opposite direction. A device to prevent this, ie, a reverse running prevention device, is installed.

As this type of reverse running prevention device, for example,
The structure described in JP-A-125295 is known. In this system, rack members are arranged side by side along an inclined track laid on a fixed structure, and claws attached to the bottom of the vehicle engage locking protrusions such as rack pins provided at a predetermined pitch on the rack members. When the vehicle starts to run in the opposite direction, the pawl engages with the rack pin to stop the vehicle.
This structure is designed to ensure safety.

[Problems to be solved by the invention] However, normally, the ascending track including the inclined track is several tens of meters long, and since the rack members mentioned above are installed in parallel during this period, the pitch of the rack pins is about 10 cm to several tens of meters.
It is set to about cm. In order for the vehicle to stop, the pawl engages with the rack pin and the load on the vehicle is supported by the rack member. When the vehicle starts running in the opposite direction, the vehicle will fall until the pawl catches the lower rack pin that it has already climbed over, and in this case, the vehicle will run in the reverse direction by a maximum of one pitch of the rack pin.

If such reverse movement is stopped by engagement between the pawl and the rack pin, an extremely large impact will occur. The magnitude of the impact varies depending on the weight of the vehicle, including the weight of passengers, the distance traveled in reverse, and the inclination of the inclined track, but the impact caused by a reverse run of several tens of centimeters is quite large; As a result, the nails dug into the rack pins, making it difficult to remove them.

In order to reduce the impact, it is possible to reduce the pitch of the rack pins to reduce the distance the vehicle travels in the opposite direction, but this would require an extremely large number of rack pins to be installed on the rack member, which can be several tens of meters long. It has the disadvantage that it is not easy to manufacture.

SUMMARY OF THE INVENTION The present invention provides a reverse running prevention device for a track running vehicle that is capable of alleviating the impact of stopping when a vehicle accidentally runs in the wrong direction and is stopped by a rack member.

[Means for Solving the Problems] In the present invention, a rack member disposed along a rising rail is movable along the rising rail with respect to a fixed structure that supports the rail, and is provided with a cushioning support. It is characterized by being supported through a mechanism.

[Function] According to the configuration of the present invention, when the vehicle starts running in the opposite direction and the pawl provided on the vehicle hits the locking protrusion of the rack member, the rack member moves along the ascending rail and this movement is prevented by the buffer support. Since it is elastically restrained by the mechanism, the vehicle can be stopped with less impact.

The rack member 20 in the straight section is shown in FIGS. 1 to 3.
It is shown in the figure and will be described in detail. Teeth 24 serving as locking protrusions having the pitch p described above are provided at equal intervals along the vertical direction of the straight portion rack member 20, and any one of these locking teeth 24 is provided with When either of the first and second pawls 10, 11 attached to the straight rack member 20 is engaged, the vehicle 6 is supported by the straight rack member 20.

Sliding seats 25 are fixedly spaced apart in the vertical direction on the back surface of the linear rack member 20, and each of these sliding seats 25 is slidably abutted on a guide seat 26, respectively.

The guide seats 26 are provided on the ring beams 4 of the fixed structure 1 described above via binding members 27.

As shown in FIGS. 2 and 3, the sliding seat 25 and the guide seat 26 are formed with a long hole 28 extending in the vertical direction on one side and a through hole 29 on the other. Guide pins 30 are inserted between the through holes 29.

Therefore, the sliding seat 25 and the guide seat 26 are connected by the guide pins 30 so that no displacement occurs in the front-back and left-right directions, but they are relatively moved in the vertical direction due to the guiding action of the elongated hole 28. possible to be connected. For this reason, the straight portion rack member 20
is movable in the vertical direction with respect to the fixed structure 1, and when the linear portion rack member 20 moves up and down, the sliding seat 25 slides on the guide seat 26.

A stopper 31 is formed at the lower end of the sliding seat 25 and abuts against the lower end of the guide seat 26 to restrict the upward position of the straight section rack member 20.

A spring 37 is stretched between them via rods 34, 35 and a turnbuckle 36.

The spring 37 is a tension spring and corresponds to the buffer support member of the present invention.

As a whole, the straight section rack member 20 is suspended by the plurality of springs 37, and the load applied to the straight section rack member 20 from the vehicle side is distributed and supported by these springs 37. .

Note that FIG. 4 is a view taken along the arrow - line in FIG. Show location.

Incidentally, the top of the pulling track necessarily forms a curved track, and a rack member is also attached to this curved track portion, and the plurality of rack members 21 and 22 described above are provided at the curved portion.

One rack member 21 is provided at a transition portion from a straight section to a curved section, and is a rack member whose radius of curvature continues to change. Further, the other rack member 22 is provided at a portion that has moved to a curved portion, and is a rack member whose radius of curvature does not change.

These curved rack members 21, 22 are shown in FIGS. 5 and 6.

These rack members 21, 22, like the linear rack member 20, are provided with locking teeth 40, 41, .

The linear portion rack member 20 and the following rack member 21 whose radius of curvature continues to change are connected so as to be relatively rotatable via a connecting bracket 42 and connecting pins 43, 44. A sliding seat 45 is attached to 42.

In addition, the rack member 21 whose radius of curvature keeps changing
and the following rack member 22 whose radius of curvature does not change are relatively rotatably connected via another connecting bracket 46 and connecting pins 47, 48, and a sliding seat 49 is connected to this connecting bracket 46.
is installed.

Furthermore, the rack member 22 whose radius of curvature does not change
Another sliding seat 50 is fixed to the tip of the slider.

These sliding seats 45, 49 and 50 are respectively connected to guide seats 51, 52 fixed to the fixed structure 1 side.
and 53, the straight portion rack member 20
They are slidably connected in the same way as in the case of .
In this case, the sliding surfaces of the sliding seat 45 and the guide seat 51 and the sliding surfaces of the sliding seat 49 and the guide seat 52 are each flat surfaces, but the sliding surfaces of the sliding seat 45 and the guide seat 51 are respectively flat surfaces. The sliding surface between the sliding seat 50 and its guide seat 53 is formed into an arcuate curved surface that shares the center point of the rack member 22 with an unchanging radius of curvature.

And the rack member 2 whose radius of curvature keeps changing
1 is suspended by a spring 37.

The operation of an embodiment of such a configuration will be explained.

When the vehicle 6 is sent from a platform (not shown) to the attitude change device 18, the attitude change device 18 changes the vehicle 6 into an upward attitude and transfers it to the rails 5,5. The above vehicle 6 was moved to rails 5, 5
When a hook (not shown) provided on the vehicle 6 is hooked onto a chain 15 serving as a traction mechanism, the vehicle 6 is pulled up by the chain 15 and raised along a vertical track and a curved track at the top.

When the vehicle 6 passes through the curved track at the top, the hook automatically disengages from the chain 15 and thereafter descends due to its own weight.

If an unexpected accident such as reverse rotation of the motor or breakage of the chain 15 occurs while the vehicle 6 is ascending, the vehicle 6 starts running in the opposite direction.

When the vehicle starts running in the opposite direction on a vertically ascending section, one of the first and second pawls 10 and 11 provided on the vehicle 6 engages one of the locking teeth 24 of the straight section rack member 20.
It hits the locking tooth 24 and locks it. Therefore, a load including the passengers on the vehicle side is applied to the straight rack member 20.

Since the sliding seats 25 of the linear portion rack member 20 are in slidable contact with the guide seats 26 on the fixed structure 1 side, the linear portion rack member 20 tends to move downward due to the sliding contact between these two sliding surfaces.

This downward movement of the straight rack member 20 is
It is transmitted to the springs 37 installed between the spring connection brackets 32 and the spring suspension brackets 33.

That is, a load from the vehicle side is applied to each spring 37, and thereby the springs 37 increase their tensile stress, and with their elastic return force, support the load and generate elastic braking force.

At this time, all the springs 37 attached to the straight rack member 20 work together, and the springs 37 attached to the rack member 21 whose radius of curvature continues to change are connected to the straight rack member 20 via the connecting bracket 42. Since the springs 37 cooperate with each other, it is possible to reliably stop the vehicle 6 from running in the opposite direction, and to reduce the impact that the pawl 10 or 11 hits against the locking tooth 24.

Even if the vehicle starts traveling in the opposite direction at a bend near the top, either one of the first and second pawls 10, 11 provided on the vehicle 6 engages the locking teeth 40..., 41... of the curved portion rack member 21 or 22. As a result, the load including the passengers on the vehicle side is applied to the curved part rack member 21 or 22, but these curved part rack members 21 and 22 are attached to this straight part rack member. 2, all the springs 37 attached to the straight section rack member 20
...and a rack member 21 whose radius of curvature continues to change
The springs 37 attached to the vehicle 6
To surely stop the reverse movement of the nail and to reduce the impact of the pawl 10 or 11 hitting the locking tooth.

Moreover, in the case of this embodiment, the vehicle 6 has two claws 1.
0 and 11 are installed spaced apart in the front and back direction, and the spacing between these is set to the pitch p of the locking teeth 24..., 40..., 41... of the rack members 20, 21, 22, which is an integral multiple of the pitch (0). (including) plus half a pitch (np+1/2・p), so if the vehicle starts running in the opposite direction, it will continue in the opposite direction until either the first or second pawl 10, 11 catches the locking tooth. The running distance,
It can be kept to less than a half pitch of the locking teeth 24..., 40..., 41.... This means that the maximum distance the vehicle can travel in the opposite direction can be halved compared to conventional vehicles with one pawl, so the inertia caused by reverse travel can be reduced and the vehicle can travel in the opposite direction when it collides with the rack member. It is possible to reduce the impact, the deformation stress of the springs 37, etc., and it is also possible to downsize the springs and reduce the number of springs used.

Note that the present invention is not limited to the configuration described in the above embodiment.

For example, the ascending trajectory is not limited to a vertical trajectory, but may also be an inclined trajectory 70 as shown by the phase image line in FIG. 7.

Further, the shape and structure of the vehicle, the mounting arrangement of the wheels, etc. are not limited to the illustrated example, and the vehicle may be a connected vehicle instead of a single vehicle.

Further, the buffer support mechanism supporting the rack member is not limited to the tension coil spring 37, but may be a compression coil spring, or may be a rubber mount structure using elastic rubber instead of the spring. It is also possible to use a damper mechanism using a gas spring or hydraulic pressure.

Further, the locking protrusion formed on the rack member may be a rack pin instead of the locking tooth.

[Effect of the invention] As explained above, according to the invention, the rack member disposed along the ascending rail can be moved along the ascending rail with respect to the fixed structure that supports the rail, and the rack member can be moved along the ascending rail and provided with a buffer. Since it is supported through a support mechanism, when the vehicle starts running in the opposite direction and the pawl provided on the vehicle hits the locking protrusion of the rack member, the rack member moves in the direction of the rising rail, and this movement is caused by the buffer. It will be elastically restrained by the support mechanism.
Therefore, it is possible to reliably stop the vehicle when driving in the wrong direction, and it is possible to reduce the impact when the vehicle is stopped. This makes it possible to reduce problems such as the claws firmly biting into the locking protrusions of the rack member.
