BRIEF SUMMARY
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a method for adjusting the position of bindings and to a device that enables adjusting the position of the bindings for fixing a player's boots on a snow board.
2. Prior Art
The positions where bindings are fixed to a snow board can vary based on the various kinds of soft or hard boots, including not only an all-round model but a free style or an Alpine model. In the past, the bindings have been conventionally arranged by a snow board instructor or shop assistant according to an instruction or an experience of such a staff. A snow board player stands with his boots on the snow board to determine a a stance, and the bindings for the boots are fixed on the snow board only from the player's body build and personal preference without any theoretical basis.
In a conventional positioning method of bindings as described above, the boots are fixed at positions where the player feels comfortable. The positions thus arranged seem to result in the most pleasant snow boarding, but such positioning is only a self-contentment of the player and makes the player tired unconsciously and retards an improvement in snow boarding technique.
It is an object of the present invention to provide a method for positioning bindings to be fixed on a snow board and a device for accomplishing the same in which an axial deviation of a player's body is calculated to fix the bindings at adequate positions on a snow board.
SUMMARY OF THE INVENTION
According to the present invention, there is provided a method for positioning a pair of bindings on a snow board which comprises the steps of detecting an angular deviation of snow board player's legs from right and left directions, calculating the angular deviation ratio between the detected right and left directions, and subsequently fixing a binding arranged at a fore position to a longer direction of the snow board so as to deviate the binding at an arbitrary angle from a long directional center of the snow board, and then fixing another binding arranged at a back position of the snow board so as to deviate the binding at an angle corresponding to the angular deviation ratio from the fore one.
Further, there is provided a device for fitting a pair of bindings on a snow board which comprises a pair of fixing means and on a base bearing center marks arranged along a length of the snow board, includes a pair of a fore and back loading disks for adjusting the angle of the bindings relative to one another.
BRIEF DESCRIPTION OF THE DRAWINGS
FIG. 1 is a plane view of a device according to the present invention;
FIG. 2 is a section taken on line I--I in FIG. 1;
FIG. 3 is a fragmentary sectional side view of a main portion of FIG. 1; and
FIG. 4 is a plane view of a fixing means.
DETAILED DESCRIPTION AND THE PREFFERED EMBODIMENTS
Characteristic features of the present invention are as follows:
1. The location or angles of bindings can be adjusted on the snow board depending on the axial deviation of the player's body. With better adjustment the snow board player can improve his snow board technique without risking injury.
2. Because of the simple structure in which the rotatable fore and back loading disks are arranged on the base of the snow board and by providing the disks with displaying marks, the present positioning device is very compact and easy to transport without any trouble.
The operation of the present device will be described in the following. A pair of boots for a snow board player are fastened to the fore and back loading disks on the base of the snow board. While keeping one of the loading disk immovable, the other disk is turned by twisting an ankle to detect an axial deviation of a free leg. Then, with respect to the other loading disk, the same procedure is repeated to detect the axial deviation of the other free leg. An axial deviation ratio is obtainable from the detected data. After a fixing position of a fore boot is settled at a front part of the snow board, the back boot is position
