BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a snowboard boot attaching / detaching mechanism capable of easily attaching / detaching a board boot to / from a snowboard.

[0002]

2. Description of the Related Art In recent years, a snowboarding competition called snowboarding has become popular in winter sports. This snowboard is different from the conventional sports where two skis are used to slide on a snow surface, and a single wide board is used to fix both feet on the single board. Is. This competition is similar to a surfboard gliding on the waves near the coast, where you don't fix your feet on the surfboard, but on the snowboard you're fixing your booted feet on the board and down the snow. is there. To glide down the snow with this snowboard,
Unlike conventional skis, instead of using a stock, you can change the direction and stop by fixing your legs on the snowboard in the shape of "C" and balancing the body, the sliding method is the same as conventional skis. Are very different. But,
This snowboard is establishing its position as a kind of snow surface sport that can be played on the ski resort in winter in recent years because of its interesting gliding.

In this snowboard, boots must be fixed on a flat and wide snowboard to connect the athlete's foot and the snowboard. The function of combining the boots and the snowboard is a major factor in manipulating the snowboard because the snowboard itself is slightly tilted and controlled by changing the position of the body weight of the athlete.

The conventional snowboard boots are
Two types of hard boots and soft boots were used. In this hard type boot, the structure of the hard type boot for skis was diverted as it was, and the binding for fixing the hard type boots to the snowboard was also the same as the structure for skis. In this hard boot, the outer shell is composed of several kinds of members, and each member is molded of hard plastic. The hard boot has a long length, and when the foot is inserted into the hard boot, most of the calf is covered. When the shell is tightened after inserting the foot into the hard boot, the part below the calf is fixed in the same manner as the boot. For this reason, the ankle is firmly fixed to the boot, and the hard type boot having the foot fixed thereto is coupled to the binding fixed to the center of the snowboard to fix the boot and the snowboard. And, this binding is provided with metal fittings that rotate before and after the hard boot, and the front and rear fittings can firmly grip the front and rear of the hard boot.

The construction of such a hard type boot and binding is the same as that of the conventional hard type boot for ski and the structure of the binding dedicated thereto. In this hard type boot, once the hard type boot is attached to the athlete's foot, it is extremely easy to attach and detach the hard type boot and the binding. To fix the hard type boot to the snowboard, you can connect it by simply fitting the metal fittings provided before and after the binding to the toes and heels of the hard type boot, and you can remove the metal fittings to release the engagement of both. The operation is simple. As described above, in the hard type boot, since the conventional ski completed technology is used, it is convenient to attach and detach the hard type boot.

However, since the hard boot has a structure in which the calf and the ankle are fixed with a hard plastic shell, there is a drawback that the steering performance of the snowboard is deteriorated. That is, when descending on a snowboard, the entire body of the athlete must be bent back and forth and left and right to change the weight position of the athlete to change the inclination angle of the snowboard. By changing the inclination angle of the snowboard, the snowboard and the competitor can turn or stop in a desired direction. However, if the ankles were firmly fixed with hard boots, the freedom to turn the ankle was impaired, making it difficult to move the weight. This has a large gap from the main purpose of manipulating the snowboard by slightly tilting it, and with hard type boots that fix the ankle including the ankle, there was a fatal injury that deteriorated the operability of the snowboard.

In contrast to the hard type boot, the soft type boot is manufactured in the shape of half-boots by using a flexible material such as artificial leather or soft vinyl as a main material. Since the outer shell of the boot is made of soft leather, the legs above the ankle can be moved back and forth, left and right relatively freely even when the boot is worn, and even if the entire foot is fixed to the snowboard. , The legs can be freely tilted with respect to the board. In this way, the soft boots can be relatively freely rotated back and forth and left and right around the ankle as an axis, so that it is possible to skillfully convey the weight shift of the athlete to the snowboard, and in competitions such as turns and jumps. It had the characteristic that it was easy for the competitors to exercise their will.

However, since the soft type boot is made of a soft material, it is not suitable for the binding for the hard type boot using the metal fitting, and the binding for the soft type boot must be used. A conventional binding for a soft boot is composed of a pedestal part formed of a reinforced plastic that adheres to the sole of the boot, and a support part that stands upright on the rear part of the pedestal and adheres to the rear side surface of the boot. The shape was slightly L-shaped when viewed.
To fix the boot with this binding, insert the bottom of the boot into the base, fit the bottom and side of the boot to the base, and attach the rear side of the boot to the inner surface of the support to secure the binding and boot. To combine. And, it was possible to tighten the toe part of the boot with the band on the front side of the binding, tighten the instep part of the boot with the band in the middle of the binding, and firmly connect so that the boot does not separate from the binding. . In this binding for a soft boot, the toe portion and the instep portion of the boot are fixed to the base portion by two bands, and the rear side surface of the boot is in close contact with the support portion. For this reason, the lower half of the boot is fixed to the snowboard via the binding, and the upper part of the ankle is not tightened. Further, the support portion is in close contact with the rear side surface of the boot and regulates the boot so as not to move back and forth. Due to this structure, even if the boot is fixed to the binding, the legs can be rotated relatively freely around the ankle, and the softness of the boot material does not hinder the movement of the athlete. It was a thing.

As described above, the soft boots and the bindings for the soft boots are sports equipment having a high degree of freedom for a snowboard player, but there are many difficulties in operating them. That is, to join the soft boot to the binding for the soft boot,
Each of the toe part and the instep part had to be tightened with a band, each binding had two tightening parts, and the left and right feet needed a total of four tightening parts. In the work of tightening this band, it is necessary to insert the band into a thin through hole, pull out the end of the band and tighten it, and it is time consuming to wear gloves with such detailed work. It was In particular, it would be annoying to the athlete if he had to bend down such a detailed work outdoors in the snow. On the contrary, when removing the soft boot from the binding for the soft boot, it is necessary to remove all the bands at four places, and in case of an emergency such as a fall, remove the boot from the snowboard. It could not be removed quickly, and it was difficult to take sufficient measures in case of an accident.

[0010]

As described above, the conventional hard-type boot can be easily attached to and detached from the binding, but since the ankle and leg are fixed by the boot, the movement around the ankle can be prevented. The degree of freedom was restricted, and there were fatal injuries that made it difficult to compete when skiing down a snowboard. Also, with soft-type boots, the legs and legs can be bent relatively freely, and the weight transfer to the snowboard can be performed sensitively, which enhances the maneuverability in competition. There was a fatal injury that was a hassle to attach and detach to and from. As described above, each of the hard type boot and the soft type boot has advantages and disadvantages, and it has been desired for a snowboarding player to develop a snowboarding boot and a binding having both advantages.

[0011]

According to the present invention, a wide plate-shaped snowboard whose lower surface contacts the snow surface, and a binding fixed to the upper surface of the snowboard,
It is characterized in that it comprises boots that can be worn by a competitor and engagement tools attached to the boots, and that the boots are connected to the snowboard by engaging the bindings with the engagement tools.

[0012] Preferably, the engagement tool includes a turning belt that is tightened around the ankle of the boot, and a pair of hanging belts that are respectively hung from the turning belt and hung at the positions of the left and right ankles of the boot. It is characterized in that it is composed of an arch plate whose both ends are connected to the lower end of the suspension belt and which is fixed to the shoe sole of the boot.

Preferably, the binding is a fixed body fixed to the upper surface of the snowboard, and a toe holder which is swingably connected to the front of the fixed body so that the toe portion of the boot can be fitted therein. It is characterized in that it is composed of a heel retainer that is swingably connected to the front and rear in the rear part of the fixed body and that is closely attached to the rear side surface of the boot to suppress the movement in the front-rear direction.

Preferably, the binding is shaped so as to be in close contact with the shoe sole of the boot, and a connecting mechanism is provided at the center thereof so as to be detachably engageable with the arch plate of the engaging tool. is there.

More preferably, the arch plate of the engaging member is provided with a round rod-shaped engaging shaft, and the coupling mechanism of the binding has an engaging claw piece having a sickle-like engaging groove rotatably pivoted. It is characterized in that the engagement groove is fitted into the engagement shaft when the engagement claw piece is rotated, and the arch plate is connected to the binding.

[0016]

In the present invention, the boot can be detachably connected to the binding by attaching the engaging tool to the conventionally used soft boot. This boot and binding can be connected and disconnected without tightening the belt, so it can be operated in cold snow with gloves on. Then, to operate the snowboard, soft boots can be mounted on the snowboard, allowing the athlete's feet to move freely without fixing the ankle like hard boots. Therefore, the weight shift of the pilot can be transmitted to the snowboard as it is, and the intention of the athlete can be surely transmitted to the snowboard even in competitions such as turns and jumps.

Further, in the present invention, the engaging member is composed of the turning belt, the hanging belt, and the arch plate, so that the soft boot can be used without being processed or damaged.

Further, in the present invention, since the binding is composed of the fixed body fixed to the snowboard, the toe presser and the heel presser which are swingably connected to the front and rear of the fixed body, the toe of the soft type boot. Can be fixed without moving upwards and without moving in its length direction. Therefore, the soft boot can be securely fixed, and the same effect as when the hard boot is fixed to the snowboard is obtained.

Further, according to the present invention, the binding mechanism is provided in the center of the binding so as to be detachably engageable with the arch plate of the engaging tool, and the arch plate can be engaged with this coupling mechanism. The hanging belt and the turning belt can be connected to the binding. Therefore, the soft boot with the turning belt tightened can be fixed to the binding.

In the present invention, the arch plate is provided with a round rod-shaped engaging shaft, and the connecting mechanism rotatably supports an engaging claw piece having a sickle-like engaging groove. Therefore, when the engaging claw piece rotates, the engaging claw piece is fitted into the engaging groove on the engaging shaft. Therefore, the arch plate can be fixed to the connecting mechanism with a simple structure.
