Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a snow slide having a steering board in front of a sliding board and a handle for turning the steering board.

[0002]

2. Description of the Related Art This type of snow skiing equipment is commercially available under the name of Snowscoot (Proto Co., Ltd./Trademark Incentives). As shown in FIG. 16, the snow scoot supports a handle post 82 by a frame 81 fixed to a slide board 80, a bar handle 84 is provided at an upper end of a handle shaft 83, and an inverted U-shaped front end of a lower end of the handle shaft 83 is provided. A steering board 86 is supported by the frame 85. The area of the steering board 86 there is considerably larger than the area of the gliding board 80, and the former area has a size close to half of the area of the gliding board 80. Also, the steering board 86
Is larger than the left-right width of the gliding board 80. Reference numeral 87 denotes a reinforcing beam.

As described above, a snow skiing tool provided with a handle device can prevent the balance of the upper body from being lost by supporting the upper body during sliding with the handle. Snow skiing equipment provided with such supports is disclosed in Japanese Patent Application Laid-Open No. Hei 7-251745,
This can be seen in JP-A-11-33159. The snow skiing device of the former publication has a pair of left and right sled plates fixed by a frame, and a bar handle is fixed to the upper end of the frame, so that the steering operation cannot be performed. In the snow glide of the latter publication, a gripping bar for supporting the upper body is protrudingly provided at the front end of the gliding board.

[0004]

The snow-slide system provided with the above-mentioned support device can support the upper body with a handle or the like. Even when unexpected movement inertia force suddenly acts, the balance of the upper body is hardly lost, and for example, it is possible to enjoy a more stable sliding as compared with a snowboard. But,
Since the frame and the handle device are provided at the front of the sliding board, the entire sliding tool is inevitably bulky, is difficult to transport, and requires a large space for storage. For example, a snowscoot cannot be stored and carried in the trunk of a passenger car, and it is necessary to prepare an automobile having a larger luggage compartment. When using a lift on the slopes, it is extremely difficult to carry a snowscoot anyway, rather than carrying it on your shoulder or holding it by hand.

[0005] As mentioned above, the area of the steering board 86 of the snowscoot is about half the area of the gliding board 80, and the width is wide. Therefore, a large force acts on the steering board 86 at the time of sliding, and a strong force is required to support the bar handle 84. Particularly when turning, the steering board 84 is pointed in the opposite direction to the direction in which the player wants to turn,
Although the sliding board 80 slides sideways, considerable arm strength is indispensable to maintain the reverse steering state of the steering board 84, and since the steering board 84 in the reverse steering state hinders turning, other snow surfaces It is hard to make small turns as compared to running equipment. Naturally, it is difficult to perform sudden braking using the edge of the sliding board 80. Since the vehicle slides while straddling the reinforcing beam 87, the shin or knee is easily injured when falling.

SUMMARY OF THE INVENTION An object of the present invention is to provide a snow slide which can be compactly folded along a slide board, so that the space for transportation and storage can be reduced, and which can be carried without any trouble even when the user rides on a lift. It is in. It is an object of the present invention to provide a braking device for reducing the sliding speed, which makes it possible to easily perform a deceleration or stopping operation without using any special sliding technique, and thus to make a collision accident or jump off the course. It is an object of the present invention to provide a snow skiing device that can prevent such problems well and is excellent in safety. SUMMARY OF THE INVENTION It is an object of the present invention to provide a snow skiing tool which can be steered lightly, can be turned with a smaller turning radius, and therefore has a small turn and excellent maneuverability. An object of the present invention is to provide a snow skiing device that can be used as a kick board that runs on a road surface by performing a relatively simple retrofitting operation.

[0007]

SUMMARY OF THE INVENTION The snow skiing device of the present invention comprises:
As shown in FIG. 1, a sliding board 1, a steering board 2 disposed in front of the sliding board 1, and a handle device 3 supported on the sliding board 1 and deflecting the steering board 2 are provided. . The handle device 3 is connected to the slide board 1 via an undulating connection structure 6, and the handle device 3
Can be raised and lowered between a use position where it stands up with respect to the sliding board 1 and a carrying position that is folded along the sliding board 1.

More specifically, as shown in FIG. 2, a brake device 7 provided on the sliding board 1 includes a brake 61 and a brake 6
1 includes a spring 62 that presses and biases 1 to a standby posture, and an operating tool 60 that displaces the brake body 61 to a braking position against the biasing force of the spring 62.

The upper surface of the sliding board 1 supports the step 5 through the frame 4 substantially parallel to the sliding board 1. The area of the steering board 2 is 15 to 35 times the area of the sliding board 1.
Set to%.

The connecting structure 6 includes a bracket 44 fixed to the front part of the step 5 as shown in FIG. 2, a connecting arm 46 fixed to the handle post 16 and supported by the bracket 44 so as to be able to move up and down. Bracket 44 and connecting arm 46
And a lock mechanism for locking the connecting arm 46 between the use position and the carrying position.

As shown in FIG. 1, the handle device 3 comprises a lower handle shaft 17 rotatably supported by a handle post 16 and an upper handle shaft movably assembled along the axis of the lower handle shaft 17. 18 inclusive.

The steering board 2 is connected to the lower handle shaft 17 via a pair of support arms 20. Step 5 removably supports the frame 4 fixed on the slide board 1. The steering board 2 and the front wheel 70 for traveling on a road surface are provided so as to be replaceable with respect to the support arm 20. The step 5 separated from the frame 4 includes a rear wheel 7 for road running.
1 is provided.

[0013]

According to the present invention, the handle device 3 is supported on the sliding board 1 via the undulating connection structure 6 so that the handle device 3 can be compactly folded from the use position during sliding to the carrying position along the sliding board 1. As a result, the outer shape of the snow skiing device during transportation or storage can be significantly reduced.
When using a lift, you can carry the folded snow skier on your knees, for example, or carry it on your shoulder via a strap, so you can safely get on and off the lift In addition, accidents such as accidental dropping of snow skiing equipment can be prevented. It is easy and easy to transport snow skiing equipment when climbing on a slope.

According to the snow skiing device provided with the brake device 7, the operating body 60 can be operated against the spring 62 when necessary, so that the braking body 61 can be cut into the snow surface to reduce the running speed. Therefore, it is possible to easily decelerate or stop the snow skiing device without using special sliding techniques, such as cutting the edge of the sliding board 1 into the snow surface and decelerating. For example, in a situation where the vehicle slides on a crowded slope, the vehicle can be prevented from colliding with another person or a protective fence. Jumping out of the forest course can be prevented well.

[0015] A frame 4 is fixed on the upper surface of the sliding board 1 and a step 5 is mounted on the upper surface of the frame 4.
When the step 5 is located at a higher position than in the case where the upper surface of the sliding board 1 is used as a tread surface, the sliding board 1 is more likely to generate a tilting moment in the left-right direction as compared with the case where the upper surface of the sliding board 1 is used as a tread. The effect of the edge such as time can be enhanced, and a snow surface gliding tool that is more effective than a snowscoot can be obtained.

The reason why the area of the steering board 2 is set to 15 to 35% of the area of the slide board 1 is as follows. As the area of the steering board 2 increases, the resistance received from the snow surface during a run increases, and the resistance of the steering board 2 when the reverse steering wheel is turned increases, so that the attitude of the steering board 2 is maintained. Requires great strength. The inventor of the present invention has found that, as a result of repeated trial runs, the upper limit of the area of the steering board 2 that allows a normal user to operate the steering wheel lightly is 35% of the area of the sliding board 1. When the area of the steering board 2 becomes small, the resistance value received from the snow surface becomes small, and the steering board 2 fluctuates and becomes difficult to stabilize even when a slight force is applied. It has been found that it is preferable that the lower limit of the area of the steering board 2 be 15% of the area of the sliding board 1 in order to stabilize the steering board 2 at the time of sliding.

A connecting structure 6 comprising a bracket 44, a connecting arm 46 pivotally supported by the bracket 44, and a lock mechanism or the like.
By operating the lock mechanism to release the lock, the entire handle device 3 can be erected and oscillated about the oscillating shaft 45, or can be tilted and oscillated to the carrying position parallel to the sliding board 1, so that the erected position and the carrying position Can be easily and promptly switched.

According to the handle device 3 including the lower handle shaft 17 and the upper handle shaft 18 which can be freely inserted into and removed from the lower handle shaft 17, the upper handle can be stored in a state where the handle device 3 is folded and stored along the slide board 1. Since the shaft 18 can be retracted and stored in the lower handle shaft 17, the folding size can be reduced by that amount, and the size can be reduced.

Instead of the steering board 2, the front arm 70 is
When the rear wheel 71 is provided on the step 5 which is supported at 0 and removed from the frame 4, the snow skiing tool can be used as a kick board provided with the handle device 3, and the snow skiing tool can be enjoyed throughout the year.
