BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a snow runner.

[0002]

2. Description of the Prior Art Among many sports equipment devised from skis and sleighs is a scooter-type snow runner that uses a sliding board instead of wheels. Such a snow sliding device which has undergone considerable research is described in, for example, US Pat. No. 4,773,659. This snow runner is intended for skiing on snow that contains some hard ice, and cannot be practically used to run on soft powder snow. This is because the snow runner sinks in the snow to the point that the directional function of the front runner fails. Moreover, such snow runners are unbalanced and unable to perform the jumps and other acrobatic glides required by many sports enthusiasts.

In order to solve such a problem, US Pat. No. 5,351,975 proposes the following snow sliding equipment. That is, the snow runner has a support on which the user's foot rests, which becomes the rear support run, which is coupled to a rigid arm and a pivot arm that can be manually controlled by a handle, and a rigid link. A flexible link connected to the front steering runner as an extension of the support runner along a horizontal axis perpendicular to the longitudinal axis of the front steering runner. This snow runner is characterized in that the tip of the steering runner is circular. The width of the supporting runner is about 2/3 of the width of the steering runner at the widest point, and the length thereof is about twice that of the steering runner. The tip of the support gliding section is curved upwards so that it is higher than the tip of the steering gliding section. By connecting the steering sliding part to the rotating arm at a length of about 1/4 from the surface of the steering sliding part, obstacles such as bumps on the ground can be cleared successfully. In addition, if the axis of the rotating arm is tilted backward by about 65 °, the maneuverability of the device is well balanced. Only the grip of the handle extending from the pivot arm is provided laterally above the connection that separates the steering slide and the support slide.
The handle extends to an adjustable joint that serves as a cap on the upper end of the pivot arm axis. The height can be adjusted by sliding on the pivot arm.

With the above-mentioned snow sliding equipment of the above-mentioned US patent, by adopting the above-mentioned structure, it is possible to realize rotation and acrobatic sliding with excellent stability and maneuverability even on soft powder snow. I was able to do it.

[0005]

However, in the snow runner of the above-mentioned U.S. Pat. No. 5,697,049, the front steering runner has a circular shape, so the straightness is not good, and in the case of bending, the snow runner does not move against the snow surface. Since the edge contact length of the steering gliding part of the above-mentioned snow sliding tool is short, there is a problem that the edge is not very effective and the direction changeability is not so good.

[0006] Therefore, an object of the present invention is to provide a snow runner which is excellent in straightness and directionality.

Such an object is achieved by the present invention described in (1) to (3) below. (1) While bifurcating from the front to the rear,
A rigid frame that extends downwards and ends with two frame extensions that extend parallel to each other and horizontally in the front-rear direction, and a snowboard-like piece that extends in the front-rear direction along the lower side of the frame extension of the rigid frame. In the state in which the supporting gliding part of, the foot supporting plate attached to the rigid frame on the supporting gliding part, and the rotation axis are inclined backward by a predetermined angle,
A rotating arm rotatably attached to the front portion of the rigid frame, a handle attached to the upper portion of the rotating arm, and is arranged in front of the supporting sliding portion, and is coupled to the lower end of the rotating arm. Steering slide, and
One end is fixed near the handle and the other end is the foot support
It is fixed to the plate and extends diagonally above the foot retention belt.
Snow runner characterized by having a winding assist rod . (2) The maximum width of the steering sliding part is larger than the maximum width of the support sliding part, and the ground contact surface part of the steering sliding part is formed in a trapezoidal shape that substantially spreads from the rear to the front, The above-mentioned snow runner (1), in which the maximum width of the ground contact surface portion is set to 1.01 to 1.1 times the minimum width. (3) The two frame extension portions extend in the front-rear direction along the upper surface of the side portion of the support sliding portion, and the foot support plate is formed of a substantially rigid body, and the side edge portions thereof are substantially formed. In the entire length, the snow sliding tool according to (1) or (2) above, which is welded to the extended portion and fixed to the support sliding portion at at least four positions on the front and rear sides thereof.

[0008]

The action and effect of the present invention is as follows.
In particular, since the shape of the steering gliding portion is configured as described above, the straightness is good, and the edge of the steering gliding portion is well effective even in a curve, and it is easy to rotate and comfortable operating performance can be obtained.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A snow ski according to a preferred embodiment of the present invention will now be described in detail with reference to the accompanying drawings.

In the case of an adult, the snow runner according to the embodiment of the present invention has a total length of about 1.50 m, and is arranged in front of the support runner 1 and the support runner 1, and the lower end of the rotating arm 4 is provided. A steering slide 2 is connected to the support slide 1 by means of a fork 3 from. The rotating arm 4 is rotatable within an exterior body 5 that is inclined (for example, 65 °) with respect to the ground. At the bottom of the exterior body 5,
Two rigid frames, that is, metal tube frames 6 are fixed (welded) at the front part thereof. These metal tube frames 6 increase the distance between each other from the front part,
After extending downward and reaching the support sliding portion 1, the frame extending portions 6a extend horizontally in the front-rear direction of the snow sliding tool and extend parallel to each other along the upper surface of the side edge of the support sliding portion 1. The rear ends of these frame extension portions 6a are inclined rearward and upward so as to be gradually separated from the surface of the support sliding portion 1, and are gradually made closer to each other, and finally integrated. This is because the rigidity is further increased by integrating them.

A foot support plate 11 on which a player puts his / her foot is arranged on the support sliding portion 1 and between the frame extension portions 6a of the metal tube frame 6. It is preferable that the main body of the foot support plate 11 is made of a rigid rectangular metal plate, and substantially the entire length of both sides of the foot support plate 11 is welded and fixed to the side portion of the frame extension portion 6a. Further, it is preferable that the foot supporting plate 11 is fixed to the supporting sliding portion 1 with screws or the like at least at four positions on both front and rear portions thereof, and is integrated with the supporting sliding portion 1. It is preferable that the metal tube frame 6 and the foot support plate 11 are welded in advance and then fixed to the support sliding portion 1 with screws or the like.
It is desirable that the foot support plate 11 has an upper surface, which is a surface on which the foot is placed, pulled by rubber or the like to prevent slippage.
A foot-holding belt 12 in the form of a sandal belt is attached to the front portion of the foot support plate 11 so as to gently hold both feet in the lateral direction or the front-rear direction.

A supporting member 9 is fixed to the upper portion of the outer casing 5 at its tip. The supporting member 9 extends obliquely downward and rearward, and its lower end is fixed to the supporting sliding portion 1 or the foot supporting plate 11 in the vicinity of the foot holding belt 12.

From the tip of the supporting member 9, a steering assisting member 10 made of a metal tube is branched. The steering assisting member 10 has its tip fixed to the supporting member 9 and extends downward and rearward from the supporting member 9 at an angle less than that of the supporting member 9.
It is fixed to. The steering assisting material 10 assists the turning by the steering gliding portion during turning, and is sandwiched by both legs of the player, so that when turning, it is easy to put weight on the inner edge of the turning and to turn easily. It is for doing. In order to efficiently transmit the force due to the weight, it is desirable that the entire foot support plate 11 is fixed to the support sliding portion 1 as firmly as possible.

As described above, the total length of the snow runner is about 15
In the case of 0 cm, the length of the support sliding part 1 is about 95 cm. In this case, the support skid portion 1 is gradually curved upward from about 1/5 of the length as viewed from the tip end portion, and is curved upward at the tip end portion to a height of 10 cm with respect to the ground. Similarly, the rear end is also curved upward so that the rearmost end is located about 1 cm above the ground. With the shape as described above, the support sliding portion 1 has a substantially rectangular grounding portion 1a formed at the substantially central portion thereof. The width of the curved distal end portion of the support gliding portion 1 is gradually narrowed toward the front.

The ground contacting portion 1a of the support sliding portion 1 has the widest width c at its tip portion, and is designed to be about 22 cm when the length of the entire support sliding portion 1 is about 95 cm as described above. Is preferred. With respect to the width of the ground contact portion 1a, the tip portion is gradually narrowed, the width e is 20 cm at the minimum portion, and is widened from there, and the width d is about 21.5 cm at the rear end portion. That is, it is a non-parallelogram and has the narrowest width at the center rear part.

It is preferable that the front and rear end portions of the steering sliding portion 2 are curved upward like the support sliding portion 1 and only the central portion thereof is the ground contact portion 2a. The steering slide 2 is the support slide 1 as described above.
When the total length is about 95 cm, the length is about 5
It is preferably designed to be 3 cm. In this steering gliding section 2, the height of the tip of the steering section with respect to the ground is about 5 cm.
It is preferable that the height of the rearmost end is set to about 1 cm. The ground contacting portion 2a of the steering gliding portion 2 is also a non-parallelogram, the width a of the rear end is the widest, 26 cm, and gradually widens, and the width b of the tip of the ground contacting portion 2a is 27 cm. That is, the ground contact surface portion of the steering gliding portion has a trapezoidal shape that spreads forward. In this respect, it is significantly different from that of the above-mentioned US patent. As described above, the maximum width of the steering slide is larger than the maximum width of the support slide.

In the present invention, in particular, due to the shape of the ground contact portion 2a of the steering gliding portion, when the steering wheel 19 is operated to the left or right during rotation, the left edge or the right edge of the steering gliding portion quickly snows. It acts on the surface and can rotate quickly and efficiently. As a result of various experiments, the same effect can be obtained when the maximum width (rear end width) of the ground contact surface portion is set to 1.01 to 1.1 times the minimum width (front end width). I know it.

The steering skid portion 2 is connected to the lower end of the fork 3 by two mounting brackets 14 and 15 at a length of about 1/4 as viewed from the rear end side. The frontmost part of the supporting slide 1 is the steering slide 2
It overlaps with the rear end in a vertically separated manner, and the overlapping length is preferably set to about 5 cm. Although not shown, a shaft that can slide in the arm in the axial direction to adjust the height is fitted to the upper end of the rotating arm. An adjustable coupling 18 projecting forward is attached to the upper end of the shaft. The coupling 18 holds a handle 19 having a length of about 70 cm in its central portion. The handle 19 is provided with grips 20 and 21 at the lateral end of the handle 19, which the player can grip and operate.
It is reinforced by 2. The front-rear position of these grips on the snow runner is preferably set between the tip of the support runner 1 and the rear end of the steering runner 2 (this means that the steering runner is positioned relative to the support runner). If it is arranged in a straight line).

Support slide 1 and steering slide 2
All are made of conventional ski and snowboard components made of synthetic resin such as wood, metal, fiberglass and carbon fiber. The underside edges of these glide parts protect against friction to the gliding surface, which is more or less ice-like, and to prevent static friction, especially in turning gliding, and to provide a so-called edge during turning. For this purpose, it is preferable to reinforce it with a sharp metal rail, so-called edge material.

In the snow sliding tool of the present invention, since the structure of the steering sliding portion is as described above,
Even if the steering gliding section 2 is turned by the steering wheel 19, the gliding course of the supporting gliding section 1 is the steering gliding section 2.
You can make a good turning gliding in accordance with the gliding course.

Thus, the device for snowsports according to the invention provides excellent stability and gliding, especially on soft powder snow, as well as in jumps and other acrobatic landslides.

The respective dimensions of the members shown in the above embodiments are generally intended for adults, but may be changed accordingly, particularly when intended for children.
