Abstract

PROBLEM TO BE SOLVED: To solve problems of a conventional roller ski that the roller ski is handled by the movement of a body weight in the same way as skiing on the snow at a place without the snow, however, a practice of moving the body weight while letting the skis slide and controlling speed by the edge operation at the same time inclining a ski board cannot be made, and therefore the technical progress of a beginner of skiing cannot be achieved.SOLUTION: A roller ski of the present invention for solving problems is configured to solve the problems by changing a structure of a ski board. A rectangular solid of the structure of the ski board is made into a sphere, and the rectangular solid of the longitudinal structure in an edge part of the ski board is made into a column member. Thereby, a frictional resistance is reduced, and the function and operation on the snow is maintained. A sphere caster for holding the sphere and an edge caster having an edge roller being the column member are made into a unit. The unit is appropriately installed in the lower surface of a snow board body such as a ski board as a caster unit. This configuration enables the practice of operation as on the snow such as the skiing at the place without the snow, and thereby the technical improvement can be obtained.

Description

  The present invention is suitable for ski practice for beginners such as children in general households, and relates to the acquisition of ski operation techniques by weight transfer similar to skiing on snow.

  Until now, roller skiing was possible due to the structure of the roller, but it was called edging using the edge of the ski at the same time as the transition from straight to slanting due to weight shift required for skiing on snow. I couldn't have the ability to control speed and direction, and I couldn't practice skiing like on snow, so I couldn't improve my ski skills.

  The present invention relates to a sphere caster having an embedded caster that holds a sphere that is slid while tilting the ski by moving the weight important for skiing and rotating in all directions and instantaneously changing the direction, and a snow ski to be performed simultaneously. The edge of the lower roller of the caster that is installed diagonally with the function of controlling the speed and direction of travel, such as edging by the edge of a ski, slips while pressing the grounding surface, making skiing difficult for beginners on the snow As with, you can practice skiing by shifting weight, which is the basics of skiing, and gain technical improvements.

  Patent No. 337999

  Japanese Patent No. 4146882

  This is an attempt to solve the problems that we had in the past, and practice similar to skiing on snow is aimed at improving ski skills for beginners, etc. in places where there is no snow. .

  Document 1 is a configuration in which a brake device is provided on a roller and does not have a function of controlling the speed and traveling direction when an edging operation is performed like a snow ski.

  Reference 2 is a structure with the function of a truck for carrying goods, and is provided with a caster and a fixed roller that can be rotated by being driven, and twists the leg to rotate the ski. Is extremely difficult. In beginner snow skiing, it is difficult to operate a long ski with legs and weight shift, but it is difficult to operate with Bogen, which is the basic practice for operating skis. After practicing edging, it is possible to proceed to a parallel turn of ski operation, which is considered difficult to acquire ski operation naturally.

  Four fixed rollers are provided at the lower center of the ski in Document 2, and the action of these rollers is equivalent to edging in snow skiing. For example, if this roller is replaced with a bicycle wheel, the bicycle is tilted and turned. Then, the centripetal force of the combined force of the normal force on the wheel and the weight (gravity) acts on the inside of the tilt, and the wheel can turn without slipping. Even if this roller is tilted and swiveled, it cannot be slid because it swirls without slipping, and it is expected that it cannot be slid like an ski on snow.

  In order to solve the above-mentioned problems, the present invention fixes a spherical caster holding a spherical body rotatably to one main surface of the ski, and obliquely outwards one main surface of the ski on both sides of the spherical caster. An edge caster that holds two rotating rollers without contacting the ground in the direction is fixed, and a skier's ski boot installation part is provided on the other main surface of the ski plate facing the spherical caster and the edge caster. The structure is characterized in that a part of the sphere and the end of the rotating roller are brought into contact with the ground by changing the inclination of the roller by moving the weight of the skier.

  The roller ski of the present invention has the above-described configuration, and the conventional roller ski could not have a function of performing a ski operation by moving the weight necessary for snow skiing. The frictional resistance in the longitudinal direction of the plate is reduced to allow free rotation, and the ski is tilted by moving the body weight, and the edging like on snow makes it possible to control the speed and direction of travel and to move while sliding, like skiing on snow. The simple operation practice allows the beginner Yui to improve skiing skills in a snow-free place, and to measure the spread of snow skiing.

  The spherical caster and the edge caster having the above-described configuration are used as a unit, and are appropriately installed on the lower surface of the ski plate, the lower surface of the board, or the lower surface of the short ski plate, thereby enabling a plurality of uses.
