Description

[Detailed Description of the Invention] (Industrial Application Field) This invention relates to a downhill skiing device for leisure, which is provided with an open channel-like downhill road and a wheeled cart for downhill running on the inner surface of the downhill road.

(Prior Art) Conventional examples of forming the inner surface of the slideway so that wheeled carts can run down and down include, for example, the patent application filed in 1983 by the applicant.
There is an invention in No. 326778 and an invention in Utility Application No. 1983-71106 filed by the same person.

The invention disclosed in Japanese Patent Application No. 62-326778 is to form a cylindrical inner surface of a slideway so that a bogie equipped with wheels can run down and down the slideway, and also to provide a parking mechanism for the bogie at the exit of the slideway and a mechanism for passenger operation. The system is equipped with a braking device that limits the speed at which the cart moves in accordance with skill.

In addition, the invention of Utility Model Application No. 63-71106 is to form the inner surface of a cylindrical slideway so that a bogie equipped with wheels can run down and down, and the running speed of the bogie is independent of the operating skill of the rider. It is designed to be braked by an automatically operated mechanical speed governor.

In all of the above-mentioned inventions, the bogie is equipped with a braking device that is manually operated by the rider or automatically operated.

(Problem to be solved by the invention) In the conventional example of a leisure slide device that runs down and down the inner surface of a cylindrical slide, the running speed of the trolley becomes excessive because the passengers seek a higher thrill. There was a problem in that an unstable situation occurred in which the cart swayed laterally while running or descending. In addition to the above-mentioned problems, when the slideway is formed in the form of an open channel, there is also the risk that the bogies may deviate from the runway and become dangerous.

This invention was made in view of the above-mentioned problems of the prior art, and it allows the wheeled bogie to run down and down stably and smoothly, and does not fall off the track. This prevents the generation of unpleasant sounds such as metallic noises from the rotating guide wheels that come in contact with the wheels, and also ensures that the brakes act strongly on the rail sections where the speed of the wheeled bogie increases, ensuring a safe overall speed. To provide a running/unloading device for leisure that can be used safely by freely controlling the running/lowering speed so that local high speeds can be enjoyed.

(Means for Solving the Problems) The leisure skiing device of this invention has a chevron-shaped convex portion along the center of the open channel-like downhill surface on which mutual pressure acts strongly on the upper end surface, and a chevron-shaped convex portion on which mutual pressure acts strongly. A convex rail with concave portions formed on both sides is provided, and has the elasticity to guide the wheeled bogie by rotating while sandwiching the concave portions of the convex rail at the bottom of the wheeled bogie. It is formed by providing a guide wheel and a rail brake device that controls the speed by contacting the chevron-shaped convex portion and the flat portion of the upper end surface of the convex rail.

(Function) Since the wheeled bogie runs down and down using the convex rails as a guide while sandwiching the recesses formed on both sides of the convex rail with elastic guide wheels, the bogie does not come off the rails and fall over even in the rotating section. Of course, the guide wheels that come into rotational contact with the rails are elastic wheels such as tires, so they turn smoothly without producing unpleasant sounds such as metallic sounds.

In addition, the upper end surface of the convex rail is formed by combining a chevron-shaped convex part and a flat part, and a rail brake device is installed at the bottom of the bogie. The mutual pressure of the wheels acts strongly and decelerates efficiently, and on flat areas formed on the rails of straight tracks, uniform mutual pressure is obtained during braking, so the running speed of the wheeled bogie can be moderately controlled and the overall speed is reduced. As a result, safe speed can be ensured.

(Example) Examples will be described with reference to the drawings.

FIG. 1 is an overall explanatory view of the downhill skiing device for leisure according to the present invention.

The downhill slope 1 is supported by a plurality of pillars 2 that protrude vertically upward from the ground and a frame 3 formed by branching out from the pillars 2, and slopes gently from the top to the bottom as a whole. Form.

The downhill path 1 is formed in the shape of an open channel having, for example, a semicircular shape or a U-shape, and descends from the entrance 6 while turning by combining a straight running path 4 and a rotating section 5 that turns in an arc shape, and descends from the entrance 6 to the exit 7. Form it so that it reaches.

Further, the straight running track 4 is provided with a descending track 9 which is a combination of a descending track that descends with a negative gradient and a rising track that ascends with a positive gradient. A descending rotation path 10 is provided and formed by combining a descending rotation section that rotates and an ascending rotation section that rotates while ascending at a positive slope.

For example, it is formed so that the maximum speed is at the bottom end of the downhill path and the minimum speed is at the top end of the uphill path.

That is, the running speed of the wheeled bogies running down and down the descending path 9 and the descending rotation path 10 is adjusted so that the speed of running down the entire runway does not become excessive. In other words,
In order to enjoy the thrill even more, high speed and deceleration to ensure safety are combined to form a vehicle that satisfies the sense of thrill as a whole. In addition, the slideway 1 provided with a rail is formed by swinging it up from side to side or by somersaulting and rotating in a loop shape to create a change.
Furthermore, the resiliency may be improved.

Further, the entrance 6 of the runway 1 is provided with a lifting device 8 for passengers such as stairs, an elevator, an escalator, or a lift.

In addition, as shown in FIGS. 2 and 3, inside the runway 1, along the center line of the running surface of the wheeled bogie,
A convex rail 11 is provided from the inlet 6 to the outlet 7. The convex rail 11 is formed to protrude vertically from the running surface of the bogie on the downhill 1.

That is, in the straight running path 4, it is provided at the lowest center of the downhill path 1, and in the rotating section 5, it is formed so as to gradually rise from the entrance of the rotating section 5 to the outer peripheral side.

Further, as shown in FIGS. 4 and 5, the convex rail 11 consists of two spaced apart boards 12, 12 that protrude vertically from the running surface of the bogie on the slideway 1, and the board 1.
A plate-shaped upper base 13 is provided which is integrally connected to the substrate 12 at the upper end edge of the base plate 2 and has a width protruding from both side edges.

The upper base 13 is formed by connecting a flat part 14 formed in a planar shape as shown in FIG. 4, and a chevron-shaped convex part 15 formed highest in the central part as shown in FIG. do.

In this case, the flat portion 14 is formed on the inner surface of the straight running path 4, and the chevron-shaped convex portion 15 is formed at a portion where the speed of the wheeled truck increases, such as at the end of the straight running path 4 and at the entrance of the rotating section 5.

Further, the convex rail 11 is connected to the wall portion of the slideway 1 and the protruding portions of the base plate 12 and the upper base 13.
A rectangular open conduit-shaped recess 16, 1 that opens outward on both sides of the

In addition, as shown in FIG. 6, the wheeled truck has a pair of guide shafts 17 spaced apart from each other at the bottom of the base of the wheeled truck, which protrude from the bottom surface of the wheeled truck and are fixed rotatably in the side direction. Provided. A resilient guide wheel 18 such as a tire is provided at the tip of the guide shaft 17, the guide shaft 17 is pulled by a spring 19, and the guide wheel 18 is loosely fitted into the recess 16 of the rail 11 by the elastic force. , are formed so as to come into contact with the substrate 12 and guide the cart.

Furthermore, the truck is provided with a rail brake device. The rail brake device is provided with a braking base 20 formed by bending a part of the truck frame upward, as shown in FIG. form. The brake base 20 is provided with a slide base 21 that slides back and forth in the traveling direction of the truck, and a brake material 22 as a wear material is mounted on the slide base 21.
to be fixed. The brake material 22 moves the slide base 21 in the traveling direction along the brake base 20 during braking by operating the pedal or brake lever on the truck frame, and the brake material 22 moves along the convex rail 11 during braking.
It is formed so as to come into contact with the flat portion 14 and the chevron-shaped convex portion 15 to brake the running and descending of the truck.

In this case, the contact surface of the brake material 22 with the convex rail 11 is formed to be parallel to the convex rail 11.

In addition, the height of the chevron-shaped convex portion 15 of the rail 11 at the exit 7 of the slideway 1 is formed to gradually increase as it advances in the traveling direction, so that the contact surface pressure with the brake material 22 of the wheeled bogie is gradually increased. A stopping device is installed to decelerate and stop the wheeled bogie by raising the height.

(Effects) Since this invention is constructed as explained above, it produces the following effects.

The wheeled bogie runs down the road with its wheels in contact with the open channel-like downhill road surface, and is guided by elastic guide wheels that are inserted into recesses formed on both sides of a convex track provided along the center of the downhill road surface. Since it runs down and down, there is no excessive shaking or vibration during running and down, and even in the rotating part, the bogie does not fall off the rails and fall or become unstable, and the guide wheels that rotate in contact with the rails are Because the wheels have elasticity such as tires, they do not produce unpleasant sounds such as metallic sounds.
You can turn comfortably and smoothly.

In addition, the upper end surface of the convex rail is formed by combining a chevron-shaped convex part and a flat part, and a rail brake device is installed at the bottom of the bogie. The mutual pressure between the two acts strongly and decelerates efficiently, making it possible to reliably control the speed at points where the speed increases and at the exit.In addition, on flat sections formed on the rails such as straight tracks, the mutual pressure is reduced during braking. It is possible to provide a leisure skiing device that operates and changes speed uniformly to smoothly control the speed during normal running and downhill, ensuring a safe speed throughout the downhill.
