  DESCRIPTION OF EMBODIMENTS Hereinafter, embodiments of a snowboard binding device according to the present invention will be described with reference to the drawings. FIG. 1 shows an exploded perspective view of a snowboard binding device according to the present invention. The binding device 1 includes a base member 10, a rotor member 20, a return means 30, a holding member 40, and a protection plate 50. In each drawing in the present embodiment, the protection plate 50 is illustrated as being transparent so that the internal structure can be easily understood.

  First, as shown in FIG. 1, the base member 10 is a disk-shaped metal member having an attachment portion 11 for attachment to a snowboard (not shown). In addition, a step portion 12 is provided at the peripheral portion of the base member 10, and an accommodating portion 13 in which the rotor member 20 is accommodated is provided inside the step portion 12.

The attachment portion 11 is a plurality of long holes provided in the center of the base member 10, and the attachment position of the binding device 1 with respect to the snowboard can be adjusted by using the long holes as described above.
Moreover, when attaching the base member 10 to a snowboard, it is preferable to use the protective member 14 made of rubber. When the protection member 14 is used, the protection member 14 also needs a long hole 14a similar to the attachment portion 11.

  An accommodating portion 13 for the rotor member 20 is formed inside the stepped portion 12. The step portion 12 prevents the rotor member 20 accommodated in the accommodating portion 13 from shifting in the lateral direction (radial direction) during sliding. Eight screw holes 15 for attaching the holding member 40 are provided on the upper surface of the stepped portion 12 at 45 ° intervals.

The accommodating portion 13 accommodates the rotor member 20 and has a diameter slightly larger than the diameter of the rotor member 20 so that the rotor member 20 can be rotated therein. The accommodating portion 13 is provided with two limiters 17 as rotor rotation preventing means for restricting the rotation so that the rotor member 20 does not rotate more than a certain angle.
In this embodiment, the two limiters 17 are attached so that the angle at which the center lines of the two limiters 17 intersect is about 90 °. However, the plurality of attachment holes 17a provided concentrically in the accommodating portion 13 can be set at any angle. Can be adjusted.

The rotor member 20 is a disk-shaped metal member, and as shown in FIG. 3, the back surface 21 is pierced and formed into a concave shape. Further, a tapered inclined portion 22 is formed at the peripheral edge portion of the upper surface portion of the rotor member 20.
The rotor member 20 is provided with a fan-shaped opening 23 having a central angle of a predetermined angle.
Further, a through hole 24 corresponding to the screw of the mounting portion 11 of the base member 10 is provided in the central portion of the rotor member 20 so that the mounting screw can be further tightened to the snowboard even in the combined state. Yes. Around the through hole 24, eight screw holes 25 for attaching the binding member 60 are provided. In some cases, the binding member may be fixed to the through hole. In this case, it is sufficient that the through hole is provided instead of the screw hole.

Between the base member 10 and the rotor member 20, as shown in the schematic explanatory view of the return means in FIG. 4, a return means 30 for returning the rotated rotor member 20 to the reference position is stretched.
More specifically, one end of the return means 30 made of a spring member is locked to a locking member 21 a provided on the back surface 21 of the rotor member 20. Then, the return means 30 composed of a spring member from one end that is locked draws a spiral at the central portion of the rotor member 20, changes the direction by approximately 90 °, and is approximately from the roller 13 b provided in the accommodating portion 13 of the base member 10. The direction of 180 ° is changed toward the center, and a spiral is further drawn and the direction of about 90 ° is changed. The other end is locked to a locking member 21b provided on the back surface 21 of the rotor member 20.

The roller 13b is rotatably provided on the pin 13a, and an E-shaped ring 13c is attached to the top of the pin 13a so that the roller 13b does not come off the pin 13a.
Although the description is omitted because it is clear from the drawings, a return means 30 having the same configuration as the return means is provided between the base member 10 and the rotor member 20 at a point-symmetrical position about the base member 10. It is being handed over.

  By adopting such a configuration, when a certain force is applied to the rotor member 20 and the applied force is released after the rotor member 20 is rotated, the rotor member 20 is The return means 30 can return to the reference position. Although the wire spring member is shown as the return means 30, the present invention is not limited to this, and a plate member or a coil spring may be used.

In addition, positioning magnets 26 are attached to the periphery of the rotor member 20 at four positions at intervals of 90 °. On the other hand, as shown in FIG. 5, a magnet 27 having a different magnetic pole is attached to a position corresponding to the magnet 26 on the back surface side of the base member 10. That is, it is difficult to return the rotor member 20 to the accurate reference position only with the above-described return means 30, and the use of the upper and lower magnets 26 and 27 described above makes it possible to return to the accurate reference position.
Note that, when the rotor member 20 leaves the reference position, the click feeling can be given to the user by the effect of the magnets 27 and 26, and the user can recognize that the rotor member 20 has moved away from the reference position. it can. Similarly, when the rotor member 20 returns to the reference position, a click feeling can be given to the user, and the user can recognize that the rotor member 20 has returned to the reference position.

Further, when a large force is applied to the rotor member 20 due to a fall or the like, the rotation of the rotor member 20 cannot be sufficiently restricted only by the return means 30. For this reason, two limiters 17 for restricting the rotation of the rotor member are attached to the accommodating portion 13 of the base member 10.
That is, when the rotor member 20 tries to rotate more than necessary, the limiter 17 contacts the end 23a (23b) of the opening 23 of the rotor member 20, and the rotation of the rotor member 20 is restricted. As a result, even if a large force is applied to the rotor member 20 due to an impact such as a fall, the limiter 17 restricts the rotation of the rotor member 20, so that an excessive load is applied to joints such as knees and ankles. There is nothing.

  The holding member 40 is a ring-shaped metal member that restricts the rotor member 20 from falling off. An inclined surface 41 corresponding to the inclined portion 22 of the rotor member 20 is provided on the inner side surface of the holding member 40. Is formed. That is, when the rotor member 20 moves upward, the movement is prevented and the dropping of the rotor member 20 is restricted. The holding member 40 is provided with a through hole 42 through which the screw 43 passes at a position corresponding to the screw hole 15 of the base member 10.

The protective plate 50 prevents snow and dust from entering from the opening 23 of the rotor member 20. As a result, the rotor member 20 rotates without being hindered by entering objects such as snow and dust. The protective plate 50 is made of a plastic thin circular plate, and is fixed by being attached by a binding member 60 so as to cover the surface of the rotor member 20. Therefore, a plurality of long holes 51 corresponding to the screw holes 25 for attaching the binding of the rotor member 20 are provided in the protective plate 50.
In addition, by forming the long hole 51 corresponding to the attachment portion 11 of the base member 10 and the through hole 24 of the rotor member 20, the screwdriver 51 is attached to the rotor member 20 while the binding member 60 is attached to the rotor member 20. Through the through hole 24, a screw for fixing the base member 10 to the snowboard can be tightened.

As shown in FIGS. 2 and 6, a communication hole 2 having an opening formed across the side wall of the holding member 40 and the base member 10 and communicating to the inside of the rotor member 20 is formed. Then, by inserting the pin 3 into the communication hole 2, the rotor member 20 is restricted by the pin 3 and the rotation of the rotor member 20 is prevented.
As shown in FIG. 6, the pin 3 has a metal cylindrical portion 3a having substantially the same length as the communication hole 2, and a bent end portion 3b protrudes from the cylindrical portion 3a. And it is comprised so that the edge part 3b may be narrowed and expanded according to a spring effect | action by pressing or releasing the pressing part 3c.
That is, the grip portion 3 c is pressed, the end portion 3 b is narrowed, the pin 3 is inserted into the communication hole 2, the press of the grip portion 3 c is released, and the end portion 3 b is locked to the inner wall surface of the rotor member 20. The rotor member 20 is fixed so as not to rotate. Thus, the binding member 60 can be fixed and slid as in the conventional case.
Further, the rotor member 20 can be rotated by pressing the grip portion 3 c, narrowing the end portion 3 b, and removing the pin 3 from the communication hole 2.
In addition, although the case where it opened across the side wall of the holding member 40 and the base member 10 as the said communication hole 2 and communicated to the inside of the rotor member 20 was demonstrated, it opened to the upper surface of the rotor member 20, and the base member 10 It may be a communication hole communicating to the inside. Even in this case, by inserting the pin into the communication hole, the rotor member 20 is regulated by the pin, and the rotation of the rotor member 20 is prevented.

In order to attach the snowboard binding device according to the present invention to the snowboard, first, the base member 10 is attached to a predetermined position of the snowboard. The positions of the magnet 27 of the attached base member 10 and the magnet 26 of the rotor member 20 are aligned, and the rotor member 20 is attached to the base member 10. At this time, as described above, the return means 30 is stretched between the base member 10 and the rotor member 20.
Then, the holding member 40 is placed on the step portion 12 of the base member 10, and the holding member 40 is fixed to the base member 10 with the screws 43.
