Description

Description: TECHNICAL FIELD The present invention relates to a belt-type on-leaf sliding device that slides on a snow-free ski resort, a turf slope of a golf course, or a dead leaf on a hillside. Is.

[Prior Art] Sliding equipment for skiing, skiing, mountain climbing, etc.
It is an exercise tool developed for sliding on grass, grass, fallen leaves, etc. on the slopes of hills, and the sliding is enjoyed instead of skiing.

The conventional runner on a leaf is a caterpillar runner that rolls two tops attached to a belt at regular intervals on two elliptical metal rails. there were. However, in this case, the fixed portion and the moving portion, that is, the contact state between the top and the metal rail is point contact, so that the friction between the two is extremely small,
It was considered too dangerous for beginners because it was too fast. Therefore, the inventor of the present invention has devised a belt-type sliding tool shown in Japanese Utility Model Laid-Open No. 63-65486. It is configured such that the rail is removed from the caterpillar type, a cylindrical roller is used in place of the top, the roller is mounted on a holding frame, and an endless belt is wound around the roller.

[Problems to be Solved by the Invention] According to this belt-type sliding tool, the contact state between the fixed portion and the moving portion, that is, the cylindrical roller and the endless belt is line contact. Therefore, the friction between the two becomes larger than that of the caterpillar type, and the above danger can be avoided.

However, even in the belt type, the part that fixes the foot (the upper surface of the body in this case) and the gliding surface (the outer peripheral surface of the lower belt that contacts the ground in this case) are usually parallel and the distance between them. Is fixed and kept constant during the run,
If there is unevenness on the sliding ground, etc. (although there is virtually no uneven ground, etc.), the part that secures the foot, and thus the foot of the planer, will violently vibrate vertically, forwards, backwards, left and right according to the unevenness There was the difficulty of tilting. If this is a normal ski, the impact on the body is moderately moderated by the bow shape having elasticity and the cushioning property of snow, but in the case of the conventional skiing equipment as described above, , This case has inflexible rigidity and the impact is directly applied to the whole body when sliding at a high speed on a relatively hard ground, and as a result, the impact may damage the legs and back. There was even.

In addition, since the distance between the part that fixes the foot and the running surface is always constant during the run, even if the runner tries to change the running direction by shifting his / her weight, he / she will feel like a normal ski with elasticity. Since the weight is not smoothly transferred to the running surface, it is very difficult to use various advanced running techniques with this runner.

Even better, it was completely impossible to adjust the same runner at any time according to the purpose of each person's run (for example, whether to perform straight downhill or turn) or the condition of the ground.

In addition, grass, lawn, dust, etc. are easily caught between the rail and the roller, between the roller and the endless belt, and between the roller and the shaft of the roller while sliding, and smooth rotation of the belt is hindered when it is caught. In addition, when it goes over a mountain on the ground, that is, when it rides on a convex part, it is decelerated and when it goes into a concave part, it is accelerated, which causes a sudden change in the running speed, which causes the planer to fall. It was connected to an accident such as.

In view of the above situation, the present invention is a belt-type sliding tool in which the speed during sliding is appropriately suppressed,
It can be freely adjusted according to the purpose of gliding, etc., and the cushioning property adapted to the ground condition etc. can be obtained, and it can prevent turf from being caught and reduce deceleration acceleration that occurs when going over the mountain on the ground etc. Therefore, it is possible to safely and comfortably slide, and further, to move the weight to the ground smoothly, the purpose is to provide a leaf sliding equipment that can use various sliding techniques Is.

[Means for Solving the Problem and Its Action] In the present invention, in order to appropriately suppress the speed during sliding, an endless belt is wound around the front and rear cylindrical main rollers,
The lower side of the belt was supported downward by a plurality of cylindrical auxiliary rollers to form a sliding surface. The effect produced thereby is as described above.

In such a structure, in order to not fix the gap between the upper surface of the body and the sliding surface, in the present invention, a plurality of auxiliary rollers that support the sliding surface are mounted on a reverse channel type disk. The disc is attached to the body via a cushioning elastic body.

If there is unevenness on the ground that slides, the disc vibrates or tilts back and forth, left and right, up and down together with the belt and multiple auxiliary rollers, but the action of the cushioning elastic body alleviates the movement with respect to the body and thus to the feet of the planer. Be transmitted.
In addition, when the slider moves the center of gravity during the run, the pressure applied to the body also changes (for example, if the body is tilted to the left, the pressure is applied to the left side of the body), but this change is mitigated by the cushioning elastic body. Then, it is smoothly transmitted to the disc, and then transmitted to the sliding surface of the belt through the auxiliary roller.

The rear end of the body so that the sliding equipment can be adapted to the purpose of the skiing (for example, whether it is going downhill or turning mainly), or to be able to respond to changes in the conditions of the ground (slope or unevenness). The shaft of the main roller is loosely inserted into a long hole which is bored in the body and extends in the front-rear direction, and the shaft is constantly biased rearward by a tension elastic body movably supported by nuts or the like to keep the main roller separation distance. It was elastically stretched so that the tension of the belt could be easily adjusted at any time.

By moving the support portion of the tension elastic body with a nut or the like, the rearward biasing force can be freely adjusted. When the elastic force of the tension elastic body is adjusted to be stronger, the rear main roller tries to move rearward through its axis and strongly tensions the endless belt wound between the front main roller and the front main roller. . The tension is also transmitted to the auxiliary rollers that support the belt downward, so that the disk that supports them is pushed up, and the buffer elastic body interposed between the disk and the body is constantly compressed strongly. Come to do. As a result, the allowable range in which the cushioning elastic body can be deformed in accordance with the movement of weight, the unevenness of the ground, etc. is reduced, and the sliding tool is suitable for direct downhill on the ground with less unevenness. On the contrary, when the elastic force of the tension elastic body is adjusted to be weakened, the rear main roller easily moves forward, and the tension of the endless belt wound between the front main roller and the front main roller is reduced. To be loosened. Further, since the pressure applied to the auxiliary roller of the endless belt is also weakened, the degree of compression of the buffer elastic body is also weakened. As a result, the permissible range in which the cushioning elastic body can be deformed according to the movement of weight, the unevenness of the ground, and the like is expanded, and the sliding tool is suitable for the ground with a lot of ups and downs and the rotation.

A plate-shaped lever that extends in the front-rear direction is installed inside the rear of the body to prevent grass and the like from being caught in the body during gliding and to mitigate deceleration acceleration that occurs when crossing mountains on the ground. , The middle of the lever is rotatably attached to the body, the front edge of the lever is locked on the rear edge of the disc, and the rear edge of the lever opens rearward in a V shape to form the inner surface of the belt. The friction body that abuts against is connected.

The grass caught by this hits the plate lever first,
Then, it is guided toward the V-shaped friction body and discharged outward from both sides of the body. The friction body is always in contact with the inner surface of the belt even if grass or the like is not caught, so that friction causes
The function of suppressing the rotation of the belt from being fast is also constantly performed.

In particular, when sliding on uneven ground, the following action is achieved in cooperation with a disc that can be tilted back and forth and vertically movable. The disc tilts forward when the runner tries to get into the recess over the ground mountain (in other words, the parallel state of the disc and the body is broken and the tip of the disc moves away from the body and the disc moves forward). Lean toward.),
It means that the forward inclination angle of the sloping ground becomes strong and the gliding speed increases, but at that time, the rear end of the disk pushes up the leading edge of the plate-like lever, and the lever moves about its axis. In FIG. 1, the friction body, which rotates clockwise and is connected to the rear end, strongly pushes down the inner surface of the belt. As a result, the frictional force of the friction body increases, and the rotational speed of the belt is suppressed. Further, at that time, the belt between the disc and the friction body is convexly refracted by the above-mentioned configuration, so that the effective sliding surface of the belt has a convex shape and is brought into close contact with the entire surface of the convex ground and is pushed down. The belt surface works to reduce the gliding speed. Also, when the runner tries to climb over the valley of the ground and ride on the convex part, the disc tilts backward, which means that the forward tilt angle of the tilted ground becomes weaker and the running speed decreases. At that time, the rear end of the disk rotates in a direction away from the front edge of the plate-like lever, and the rear end of the lever can be easily rotated upward. That is, the effective gliding surface of the belt easily bends along the concave ground. As a result, the frictional force of the friction body is reduced, the braking action on the belt is weakened, and the sliding speed is increased.

If the above means are combined, the above-mentioned various operations are superposed.

[Advantages of the Invention] According to the present invention, compared to the caterpillar-type sliding gear, the sliding speed is moderately suppressed, so that not only a safe and comfortable downhill can be enjoyed, but in addition to the following, A remarkable effect is exhibited.

Even if there is unevenness on the ground or the like, the impact caused by the unevenness is transmitted to the foot of the skier by being relaxed, and the foot or waist is not hurt.
Further, since the movement of the center of gravity by the skier is smoothly transmitted to the skid surface via the cushioning elastic body, operability is improved and various advanced skiing techniques can be used. That is, the conventional sliding gear is generally suitable only for direct downhill skiing, but according to the present invention, Welden, parallel, stem turn, plukebogen, step turn, etc. can be easily performed.

Further, since the belt tension can be adjusted to appropriately change the deformation allowable range of the cushioning elastic body, for example, an advanced person who mainly wants to perform high-speed straight descent may increase the belt tension. However, for a beginner who mainly wants to rotate at a slow speed, the tension of the belt may be adjusted to be weakened. In this way, one sliding tool can be adjusted and changed to the optimum one according to the individual difference of the skier, the purpose of the skiing, the unevenness of the ground, and the like.

Furthermore, since grass, lawn, dust, etc. are prevented from being caught in the body, it is possible to prevent accidents such as being caught and stopping the rotation of the belt and tipping over, and the inclination according to the inclination angle of the ground. When you come to a strong place, you can brake the sliding equipment, and when you come to a place where the inclination is weak, you can automatically release the brake, etc., to mitigate sudden changes in speed and maintain a comfortable running condition.
