Description

[Detailed description of the invention] (Industrial application field) This invention utilizes a mountain slope, a hill or an artificial slope such as a ski resort, and has an open channel-like traveling path and a cylindrical traveling path having an arc-shaped cross section. To form a continuous running path, and when a bogie with wheels inclined downwardly downwards when viewed from the front runs down in this running path, the bogie moves along the course of the open channel running path. The bogie was always pushed back smoothly to the center without straying, jumping over the swivel part, and becoming unsteady or overturning. The present invention relates to a travel path of a leisure running device.

(Problems to be Solved by Conventional Techniques and Inventions) A bogie equipped with wheels that are inclined so that the lower part spreads, and in order to increase the running speed when running down an open channel-shaped traveling road having an arc-shaped cross section. It is necessary to make the running cotton smooth and inclined.

In the turning section of the open channel-like running path that was smoothly inclined in this manner, the bogie was swung to the outer peripheral side by centrifugal force.

Therefore, as a conventional example in which a guide for preventing a bogie from jumping out is provided at the opening edge of an open channel-shaped runway having an arc-shaped cross section, there has been proposed, for example, Japanese Utility Model Application Laid-Open No. 2-15195 made by the applicant. The pop-out prevention guide of the present invention is provided with a rectangular rod-shaped guide board of a rubber-based material or a synthetic resin material formed by molding an edge thereof, and one end of the guide board is provided with an arc-shaped section of an open channel-shaped runway. It is formed to protrude inward.
Since the guide board of this conventional example protrudes inside the runway, it hits the side surface of the wheel of the traveling trolley and has a drawback such as being a cause of deceleration.

Further, there is a conventional example in which a guide board wall having an arc-shaped cross section is provided so as to be smoothly continued from the outer peripheral running surface of the turning section of the running path at the same curvature as that of the running path having an arc-shaped cross section. In this conventional guide board wall having an arc-shaped cross section, since the bogie runs on the guide board wall and runs, the center of gravity of the bogie that has run off is deviated inward from above between the left and right wheels, and the bogie is inclined inward. There was a concern that the running posture of the trolley would be unstable, which could cause a fall.

Furthermore, a conventional example in which a cornering guide for facilitating the turning of the bogie is provided on the running surface on the outer peripheral side of the turning portion of the runway is disclosed in, for example, Japanese Utility Model Application Laid-Open No. 2-102291. The cornering guide of the present invention is formed by integrally molding the downhill surface into a mountain-shaped band, and gradually increasing the undulation so as to have the maximum height at the maximum turning portion. In other words, this conventional cornering guide
Because it is molded integrally with the running path and the undulation is changed, it is difficult to manufacture a large number of things with uneven shapes and dimensions, which increases the cost, and the wheels are chevron shaped. There were problems such as riding on the upper surface of the vehicle.

This invention was made in view of the above-mentioned problems,
Its purpose is to prevent movement of the wheels of the bogie to the outside at the lower portions of the vertical walls at both ends of the open channel-shaped runway having an arc-shaped cross section, regulate the traveling direction by guiding, and get on the bogie. While preventing the running speed of the bogie from being reduced by the side of the wheels hitting the guide board etc., and guiding the bogie smoothly to the center of the running path,
An object of the present invention is to provide a traveling path on which the posture of the cart is stable and the vehicle can travel safely.

(Means for Solving the Problems) The traveling path of the leisure run-down device according to the present invention includes a channel-like traveling path having an arc-shaped cross section provided on a slope, and a wheel inclined downward and downward when viewed from the front. In the descending device that runs down with the bogie provided with, in the vertical direction, the arc-shaped cross-sectional curvature of the running road and the discontinuous cross-sectional bending point are defined as the boundary start end over both end edges of the open channel-shaped running road having the arc-shaped cross-section. It has a rising wall that rises.

(Effect) From a road surface having a gradual curvature over both end edges of an open channel-like traveling road having an arc-shaped cross section, the cross-sectional curvature and a discontinuous cross-section bending point are used as a boundary start end, and a vertically appropriate predetermined height. The rising wall that rises in the shape of a vertical flat strip is bent, so that the tread surface of the wheel that is inclined in the shape of "C" hits the lower part of the rising wall that rises in the shape of a vertical flat strip. While being prevented from moving outward, the wheels are guided by a vertically rising wall to restrict the traveling direction, and the bogie is pushed back toward the center of the open channel traveling path. Therefore, even if the bogie is meandering or swinging in either direction, the tread surface of the wheel is always pushed back to the center part against the rising wall that rises vertically on either side, and the running posture of the bogie is unstable From a normal state to a straight and stable state.

In addition, since the bogie is prevented from excessively rising outward from the center due to centrifugal force at the turning part of the open channel traveling path, and it does not ride on the rising wall rising in the shape of a vertical flat band plate, the bogie and The bogie smoothly runs on the turning part of the open channel-shaped traveling path without the passenger falling inward to lose balance and fall.

Also, the lower tread surface of a wheel that is inclined downward and open from the front abuts near the lower corner of the rising wall that rises in the shape of a vertical flat band plate, and the side surface of the wheel is separated from the rising wall that rises vertically. Since the rising wall that rises vertically does not hit the side of the wheel at all, the speed of the bogie does not abnormally decrease and suddenly stops, and the bogie does not lose its balance due to being caught, the bogie follows the traveling direction The vehicle is guided smoothly.

(Embodiment) An embodiment of a travel path of a leisure running device according to the present invention will be described with reference to the drawings.

FIG. 1 is a perspective explanatory view in which a part of an open channel-like traveling path is omitted,
FIG. 3 is an explanatory diagram showing a traveling state of the bogie on an open channel-like traveling path.

As shown in FIG. 1, the open channel traveling path 1 has a cross section orthogonal to the traveling direction formed in an arc shape, and extends over both end edges of the open channel traveling path 1 having the arc section. Road 1
In order not to protrude or protrude into the inside of the roadway, rising walls 2, 2 'which rise vertically with the arcuate cross-sectional curvature of the running path 1 being a boundary starting point at a discontinuous cross-sectional bending point are provided. In other words, the rising walls 2, 2 'rising vertically are:
A wall that rises from a curved surface of the open channel-like traveling path 1 having a gentle curvature and has a vertical flat plate-like shape has an appropriate predetermined height in a brim shape and is bent and integrally formed. The upper ends of the rising walls 2, 2 'which rise vertically are formed so as to extend horizontally outward and bend downward to protrude outside the runway for danger prevention and reinforcement.

As shown in FIG. 3, the bogie 5 traveling on the inner surface of the open channel-like traveling path 1 having this arc-shaped cross section has wheels of the bogie 5 as viewed from the front so that steering performance and running stability can be obtained. Each of the front two wheels and the rear two wheels is formed so as to open downward as viewed from the front, that is, to incline in a “C” shape that narrows upward and expands downward.

As described above, the rising walls 2, 2 'that rise in the shape of a vertical flat strip are formed over both edges of the open channel-like traveling path 1 having an arc-shaped cross section with a gentle curvature. At the lower part of 2, 2 ', the tread surface of the wheel inclined in the shape of "C" is prevented from moving outward, and the wheel is guided by a rising wall 2, 2', which rises vertically. The direction of travel is regulated,
Even if the wheel slips, that is, slides sideways and the bogie 5 swings or snakes to the left or right, the tread surface of the wheel hits near the lower corner portion of the rising wall 2, 2 'that rises vertically to the left or right. The slip stops, and the bogie 5 is always pushed back to the center of the open channel traveling path 1, so that the running posture of the bogie 5 is corrected and stable running can be continued.

Further, in the turning portion of the open channel-like traveling path 1, the wheels of the bogie 5 are prevented from moving outward by the rising walls 2, 2 'rising up in the shape of a vertical flat band plate, and are guided while traveling outward. Is prevented, and the wheels of the bogie 5 are prevented from riding on the rising walls 2, 2 'which rise vertically, and the bogie 5 is pushed back to the center of the open channel-shaped traveling path 1, so that the bogie 5 is centrifuged at the turning portion. The bogie 5 can smoothly travel on the turning portion along the traveling direction without being excessively raised outward due to force, slip, or the like, becoming unstable or overturning.

In addition, the tread surface at the lower part of the wheel is guided while being in direct contact with the vicinity of the lower corner portion of the rising wall 2, 2 'where the vertical tread surface rises.
It is in a state separated from 2 ', and the side of the wheel does not contact the rising wall 2, 2' rising up at all, so
The speed of the cart 5 does not abnormally decrease or the posture becomes unstable, and the cart 5 turns smoothly and safely.

As described above, since the tread surfaces of the wheels of the bogie 5 are guided by the rising walls 2, 2 'that rise vertically, the bogie 5 does not jump out of the channel-shaped traveling path 1.

FIG. 2 is a perspective explanatory view in which a part of a cylindrical traveling path is omitted,
FIG. 4 is an explanatory diagram showing a traveling state of the bogie on a cylindrical traveling road.

A guide band 4 is attached to the traveling surface of the cylindrical traveling path 3 on the outer peripheral side of the turning portion by attaching or the like in a band shape toward the traveling direction. The guide band 4 is formed of a rectangular or cross section made of a synthetic resin material, a rubber material, or the like, or a band-like shape having a large number of mountain-shaped portions protruding from a flat plate or a flat plate. A plurality of sheets may be provided by sticking, or may be mounted by a detachable mounting means such as an embedded type, a fitting type, or a screw. Further, the thickness of the guide band 4 is determined at a height at which the wheel does not get over, according to the rising locus of the wheel.

As shown in FIG. 4, the bogie 5 hits the lower tread surface of the wheel along the edge of the guide band 4 without excessively rising to the outer peripheral side at the turning portion of the cylindrical traveling path 3. Since it is guided and pushed back downward, it does not float up due to centrifugal force and becomes unstable or overturned, and runs smoothly while turning. In addition, even if the wheel slides or slips, it is pressed by the guide band 4, so that the running posture of the carriage 5 is stabilized.

(Effects) Since the travel path of the leisure running device according to the present invention is configured as described above, it has the following unique effects.

A rising wall that rises vertically is provided over both edges of the open channel-shaped traveling road having an arc-shaped cross section, with the arc-shaped cross-sectional curvature of the traveling road and a discontinuous cross-sectional bending point as a boundary start end. Even if it is meandering or swinging in the direction of the bogie, the wheels of the bogie will be blocked at the beginning of the boundary, which is the discontinuous cross-sectional bending point of the rising wall that rises vertically at either end of the open road The wheels are guided by this boundary start end and the traveling direction is regulated, and are constantly pushed back to the center smoothly, the posture of the bogie is corrected and stabilized, and the bogie can continue to run safely.

In addition, the bogie is guided by the vertical rising wall on the outer peripheral side at the turning portion of the culvert-shaped traveling path, and the wheels of the bogie are prevented from climbing and pushed back to the center of the traveling path, so the bogie is subjected to centrifugal force and The bogie can be guided along the traveling direction and run smoothly on the revolving portion without excessively rising outward due to slippage or the like, without becoming unstable in posture or falling down.

Also, the lower tread surface of the wheel, which is inclined downward and open when viewed from the front, abuts against the lower portion of the vertically rising rising wall, and the side surface of the wheel is separated from the vertically rising rising wall. Since the rising wall that rises vertically does not hit at all, the truck can continue running smoothly and safely without abnormally decreasing the speed of the bogie.
