Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention is a structure for skiing on water and snow, which was devised as a vehicle for skiing for people with disabilities and sports equipment for recreation. Specifically, several parts of a commercially available off-road cycle were removed. It is designed to be used as a vehicle by attaching the sliding body devised at the bottom, and even for a healthy person, if the handlebar shape is sporty, it can be used as a large-scale ski competition.

[0002]

[Prior art]

 Conventionally, there are chair skis for disabled people as this type of vehicle, but since there is no handle, it is not possible to change direction easily, and I think that it is difficult for a veteran skier to get on and mature. (Actually, it is not used in snow festivals for people with disabilities)

In addition, probably because of the small number of users and the number of products produced, it is very expensive and even a group of persons with disabilities cannot purchase it as equipment.

[0004]

[Problems to be solved by the device]

 The former, the direction changing method described in the prior art, was a solution because it uses a robust bicycle (off-road cycle), so stability is good and the steering direction can be easily selected by the steering wheel.

The latter described in the prior art has a structure that can be mounted on a bicycle (mostly off-road cycle car body) that is commercially available and used, and there are many commercially available components that are also commercially available. I was able to solve the problem of cost.

Further, since it is also used for the off-road cycle, there is an advantage that it can be used as a bicycle by removing the front and rear sliding bodies and mounting the original parts without modifying the vehicle body.

[0007]

[Action]

 The front and rear of the invented sliding body can be easily attached and removed without using any tools or parts, and can be stored in a wheel bag for a bicycle, which is convenient for carrying without taking up space.

[0008]

[Effect of device]

 The present invention has the above-mentioned structure and configuration of the trailing edge, and has the following effects.

In claim 1, various kinds of off-road cycles are currently produced and marketed, but there are few mounted parts and they are easy to remove, so that they can be used for almost all vehicle types and are easy to produce and inexpensive.

The front sliding body according to claim 2 has a small number of processed products and uses a large number of commercially available parts, so that the structure is easy and the appearance is excellent. Moreover, the strength adjustment of the shock absorber spring is made. Because it is possible, the direction change performance is increased, and you can slide and move as you wish and even beginners can ride.

According to a third aspect of the present invention, there is provided the after-mentioned planing body. The skid of the ski can be used by the stopper shaft, and the direction change performance and cushioning property are improved even in the place where the unevenness is severe. Also, since two skis are used, the stability is good and there is no anxiety.

According to the fourth aspect, since the special aluminum plate material having a thickness of about 4 mm is used, the weight is light and the processing is easy, and the strength is sufficient.

According to the present invention, the rotation range is determined by the relationship between the moving distance of the wire and the diameter of the winding portion, and since many commercially available parts are used, the processing cost is not so high and the blade plate The braking effect can be changed by changing the shape.

According to the present invention, since the brake mounting pedestal (cant pedestal) peculiar to the off-road cycle is used, it is possible to equip the shock absorber with sufficient strength, and this pedestal must be present. For example, it may not have been possible to devise this idea, and since the shock absorber mounting position can be adjusted, the spring force can be selected according to the weight, and the direction changeability has increased and the ride comfort has improved.

According to the seventh aspect, the vehicle body mounting position of the off-road cycle can be adjusted up and down, and various kinds of delicate spring force can be adjusted from the mounting position with the stopper shaft.

[0016] According to the present invention, the mounting position of the shock absorber and the vertical position of the stopper shaft can be adjusted, the deflection of the ski can be adjusted, and the spring force of the shock absorber can be adjusted. Is a metal fitting that uses a brake mounting pedestal (canch pedestal) that is unique to the off-road cycle. If this pedestal did not exist, there was no idea of this time.

In claim 9,

According to the above.

In claim 10, the structural principle is also

According to the above, the structure is simplified.

In the ball joint contact mechanism of claim 11, since the rear part of the rear sliding body floats vertically and horizontally with respect to the vehicle body like a vane, a rotating body provided on an axis for suppressing the movement to the left and right, By combining it with a ball joint, it has a structural structure that can move up and down but cannot move to the left and right. Also, since the mechanism works slightly depending on the size of the car body, the distance between the ball joints can be changed. The adjustment was made using a clamp. (This mechanical structure is the most important one in this invention and worked best.)
