Hereinafter, an operation of the snowboard binding according to the first exemplary embodiment will be described.

FIG. 7 is a lateral view of a locking state of the snowboard binding according to the present invention. FIG. 8 is a lateral view of a release state of the lever 150 of the snowboard binding according to the present invention. FIG. 9 is a lateral view of a pivot state of the high back 120 of the snowboard binding according to the present invention.

As shown in FIG. 7, when the high back 120 rotatably installed in the rear of the side wall 112a of the base 110 through the hinge shaft H stands vertically and the lever 150 pivots in the locking direction, the foot cover 130 is pulled to the base 110 by the first wire 140 and the high back 120 is limited in pivoting to the unlocking direction, i.e., to the rear side by the second wire 160.

Referring to the installation state of the first wire 140, while the first end of the first wire 140 is fixed to the first side of the lever 150, a second end of the first wire 140 is fixed to the second side of the lever 150 through the connection path 122a of the high back 120, the third path 133 of the foot cover 130, the path 114b of the base 110, the first path 131 of the foot cover 130, the path 114a of the base 110, the second path 132 of the foot cover 130 and the connection path 122b of the high back 120 (refer to FIG. 6).

If the lever 150 pivots in a direction pulling the foot cover 130, i.e., in a locking direction as in FIG. 7 while the base 110 is connected to the foot cover 130, high back 120 and lever 150 by the first wire 140, the first wire 140 connected to the first insertion opening 152 of the lever 150 through the connection path 122a of the high back 120 is pulled. The first wire 140 connecting the foot cover 130 and high back 120 is pulled in the direction of the lever 150 as a result of the pivoting of the lever 150, and pulls the rear end of the foot cover 130 to the high back 120. Then, the first wire 140 connecting the foot cover 130 and the base 110 pulls the front end of the foot cover 130 to the base 110.

As the foot cover 130 is pulled to the high back 120 and the base 110 as a result of the pivoting of the lever 150, tow and top areas of the boots located among the base 110, high back 120 and foot cover 130 are firmly tightened.

The connection path 122a of the high back 120 and the first insertion opening 152 of the lever 150 are formed in a side facing the direction in which the lever 150 pivots in a release direction based on the pivot axis 151 of the lever 150. Accordingly, while the lever 150 pivots in the locking direction, the first wire 150 connecting the high back 120 and the lever 150 pulls the lever 150 in the locking direction and the pivoting of the lever in the release direction is prevented.

The foot cover 130 maintains a predetermined distance from the base 110 by the tube 144 and spring 142 inserted into the external side of the first wire 140 exposed between the foot cover 130 and the high back 120 and base 110 while being connected to the base 110, high back 120 and lever 150 by the first wire 140, and the spring 142 maintains an elastically compressed state.

Referring to an installation state of the second wire 160, while a first end of the second wire 160 is fixed to the side wall 112a of the base 110, a second end thereof is fixed to the side wall 112b of the base 110 through the connection hook 124a of the high back 120, the second insertion opening 153 of the lever 150 and the connection hook 124b of the high back 120 (refer to FIG. 6).

Like the first wire 140, the connection hook 124a of the high back 120 and the second insertion opening 153 of the lever 150 are located in a side facing the direction in which the lever 150 pivots in a release direction based on the pivot axis 151 of the lever 150. Accordingly, while the lever 150 pivots in the locking direction, the second wire 160 connecting the connection hook 124a of the high back 120 and the second insertion opening 153 of the lever 150 maintains a tightly pulling state and provides tension in the locking direction of the lever 150, and thus the pivoting of the lever 150 in the release direction is prevented. As the second wire 160 between the base 110 and the high back 120 is pulled tightly, the high back 120 is prevented from pivoting backward.

The releasing operation of the snowboard binding according to the present invention will be described.

If the lever 150 rotatably assembled to the bracket 126 of the high back 120 by the pivot axis 151 pivots in the release direction (arrow direction) as in FIG. 8, a distance between the first insertion opening 152 of the lever 150 and the connection path 122a of the high back 120 indicated as “L1” in FIG. 7 becomes short as indicated as “L2” in FIG. 8, and the pulling force of the first wire 140 to the foot cover 130 is released.

If the first wire 140 becomes loose, the spring 142 which has been elastically compressed from the exposed part of the first wire 140 restores to its original state and spaces the foot cover 130 from the base 110 and the high back 120.

Also, as the distance between the connection hook 124a of the high back 120 and the second insertion opening 153 of the lever 150 becomes short, the second wire 160 connecting the base 110 to the high back 120 and lever 150 and fixing the locking location of the high back 120 becomes loose, and the high back 120 may freely pivot centering on the hinge shaft H.

When the high back 120 may pivot as in FIG. 9, the high back 120 fully pivots backward to increase the gap between the high back 120 and the foot cover 130. In such a state, the high back 120 does not interfere with the heel of the boots, and the boots may be easily put on or taken off.

The locking operation of the snowboard binding according to the present invention is performed in a reverse order of the release operation. As in FIG. 9, if the high back 120 pivots to support the heel of the boots as in FIG. 8 and the lever 150 in the rear of the high back 120 pivots in the locking direction as in FIG. 7 while the boots are inserted into the space between the foot cover 130 provided at a space from the front end of the base 110 and the high back 120 rotatably installed on the rear of the base 110 as in FIG. 9, the first wire 140 is tightly pulled, and the foot cover 130 simultaneously tightens the toe and angle areas of the boots, and the second wire 160 is tightly pulled and fixes the locking location of the high back 120.

Accordingly, the present invention enables a user to fix or release the foot cover 130 of the front part of the boots and the high back 160 in the rear part of the boots at a time by using the lever 150 and is promptly attached or detached and is easy to use.

FIG. 10 is a front view of the first wire length adjusting means of the snowboard binding according to the present invention. FIG. 11 is a lateral sectional view of the first wire length adjusting means in FIG. 10. FIG. 12 is an operating sectional view of the first wire length adjusting means of the snowboard binding according to the present invention.

As shown in FIG. 10, while the rotating member 173 is rotatably inserted into the installation groove 171c of the moving body 171 provided in the rear of the lever 150, an end part of the first wire 140 inserted into the inside of the lever 150 through the first insertion opening 152 of the lever 150 is inserted into the rotating member 173.

The male screw 174 formed in an end part of the first wire 140 is coupled to the female screw 173a of the rotating member 173 by screw, and the length of the first wire 140 is adjusted along a rotation direction of the rotating member 173. The rotating member 173 is provided in both ends of the first wire 140, respectively, and both sides of the first wire 140 may be individually adjusted according to a user's shape.

As in FIG. 11, the moving body 171 is fixed to the lever 150 by the coupling member 175 penetrating the opening 171b. The first uneven part 171a formed in the internal side of the moving body 171 is engaged with the second uneven part 172 formed in the rear of the lever 150 and the vertical movement is limited.

If the coupling member 175 is rotated in a release direction and the moving body 171 is released as in FIG. 12, the first uneven part 171a of the moving body 171 is separated from the second uneven part 172 of the lever 150 and the moving body 171 moves vertically within the scope of the opening 171b of the moving body 171. The first wire 140 whose both ends are controlled by the moving body 171 is adjusted in length by the vertical movement of the moving body 171.

As described above, in the case of the first wire 140 whose both ends are controlled by the moving body 171, the length of both ends of the first wire 140 is adjusted at a time if the first wire 140 moves vertically with respect to the moving body 171. If the rotating member 173 installed in both sides of the moving body 171 is rotated, the first wire 140 in both sides may be adjusted individually and the length of the first wire 140 is adjusted in duplicate through the vertical movement of the moving body 171 and the rotation of the rotating member 173 to thereby increase the scope of adjusting the length of the first wire 140 within a narrow area.

Although a few exemplary embodiments have been shown and described, it will be appreciated by those skilled in the art that changes may be made in these exemplary embodiments without departing from the principles and spirit of the invention, the range of which is defined in the appended claims and their equivalents.
