Description

The present invention relates to a plate for snowboard bindings.

2. Description of the Related Art A snowboard binding plate is known that aims to provide snowboarders with the inherent flexibility of a binding (for example, see Patent Document 1). Such a conventional plate is fixed by engagement with a center hole, which is a through hole previously formed in the sole of the binding. In particular, the structure of the plate disclosed in Patent Document 1 was revised from that of the commercially available plate, and it gave the user a new sense of flexibility.

In recent years, there has been a desire to attach a sensor to the snowboard body to obtain data while the snowboard is running, such as the rotation angle and downhill speed of the board body while the snowboard is running. Alternatively, there is also a desire to store some kind of accessory attached to the board body. Alternatively, there is also a desire to attach a GPS device to the board body for purposes such as theft prevention. These are, in other words, the desire to attach some kind of case to the board body.

International Publication No. 2018/189984

However, since the board body is substantially plate-shaped, it is difficult to process the board body to attach such a case. Furthermore, since the binding attached to the board body is formed of the minimum necessary structure, it is difficult to attach such a case. Processing the board body or binding to form a place for attaching such a case may affect the maneuverability and running performance of the snowboard. For this reason, it is not preferable to perform any processing on the board body or binding that would change the current external shape. Therefore, it is currently difficult to attach sensors, accessory cases, or GPS devices to the board body or binding without affecting running performance.

The present invention takes the above-mentioned conventional technology into consideration, and allows a space to be formed in the board body and the binding without affecting the operability or running performance of the snowboard, and the case can be reliably accommodated in that space. The purpose is to provide a plate for snowboard binding.

In order to achieve the above object, the present invention includes a ring that engages with a center hole that is a through hole formed in the sole of a binding that is to be attached to a substantially plate-shaped board body, and a ring that engages with the center hole. The cups are fitted together, and include a bottom portion forming the bottom surface of the cup, a side portion extending upward from the outer peripheral edge of the bottom portion, and a side portion extending outward from the upper end of the side portion. a cup including a flange portion, a screw hole provided through the bottom portion through which a screw screwed to the board body is inserted, and an insertion hole corresponding to the screw hole. To provide a snowboard binding plate characterized by comprising a case housed in the cup.

Preferably, the bottom portion has a flat area with a flat surface extending circularly from the center to a portion including the screw hole, and the bottom surface of the case is formed to have a flat surface on the entire surface, and The flat area and the bottom surface of the case are in close contact.

Preferably, the bottom portion has a hole, which is a through hole, in the center thereof, and at least one bridge portion is formed to cross the hole.

Preferably, a convex portion and a concave portion are formed so as to have a concave and convex shape that is continuous in the circumferential direction of the ring, and the convex portion and the concave portion are formed continuously from the upper surface to the inner surface of the ring. .

Preferably, a locking piece protrudes upward from an outer peripheral edge of the upper surface of the ring, and a notch is formed on the outer peripheral edge of the flange to fit the locking piece. .

According to the present invention, the case is accommodated in the space within the cup that constitutes the plate accommodated in the sole of the binding, so there is no need to modify the board body or binding that is conventionally used. Therefore, a space can be formed in the board body and the binding without affecting the operability and running performance of the snowboard, and the case can be reliably accommodated in the space. In addition, since the case has an insertion hole that corresponds to the screw hole, the head of the screw placed in the screw hole protrudes into the insertion hole and fixes the position of the case, causing the case to move in the circumferential direction. Rotation is prevented. At this time, if the screw hole is perfectly circular, rotation of the case as well as the cup is suppressed.

In addition, the flat area placed at the bottom of the cup and the bottom of the case are in close contact with each other in a flat, flush manner, so even if the plate is pressed by stepping on it, the entire flat surface will not receive the force. This can prevent damage to the case as much as possible. Further, by providing the flat area, the case does not wobble, and the height of the case can be made approximately the same as the height of the side part, so that the space inside the cup can be used efficiently.

Further, by providing the holes, flexibility can be imparted to the plate as a whole, and furthermore, by providing the bridge portions here, a certain degree of rigidity can also be imparted. That is, if only the holes were used, it would be too soft, which would affect the operability, but by providing at least one bridge, rigidity can be imparted, and operability that is neither too soft nor too hard can be provided. This contributes to the fact that even if a space is provided on the plate to accommodate the case, the operability and running performance of the snowboard will not be affected.

Further, by providing the ring with the convex portion and the concave portion, the ring itself becomes easily twisted, and a certain degree of flexibility can be imparted to the plate. Therefore, just the right operability can be provided to the user. This contributes to the fact that even if a space is provided on the plate to accommodate the case, the operability and running performance of the snowboard will not be affected. Moreover, the presence of the convex portions and concave portions allows the shape to change somewhat due to contraction during molding with a mold. This leads to improved productivity.

In addition, since the locking piece and notch are formed on the outer peripheral edge of the ring and flange, the strength can be improved more than by providing a hole in the flange and fitting a protrusion protruding from the ring into the hole. can. That is, it is not preferable to form such protrusions on a resin ring because it easily breaks and the strength is low.

FIG. 3 is a schematic view of the cup and ring fitted into the board body via the binding. It is a schematic plan view of a cup. FIG. 3 is a schematic plan view of the ring. FIG. 3 is a schematic bottom view of the ring. It is a schematic diagram showing an example of a case.

As shown in FIG. 1, a snowboard binding plate 1 according to the present invention is housed in a binding B that is to be attached to a board body (not shown) having a substantially plate shape used for snowboarding. . The binding B is for securing the snow boots worn by the user, and allows the user to slide on the snow surface as one with the board itself. The binding B has a base plate B1 in close contact with the board body at the sole of the foot, and the plate 1 is accommodated in a center hole B2 which is a through hole formed in the base plate B1. Note that after the plate 1 is accommodated in the center hole B2, a cover material (not shown) made of a flexible material is covered thereon. This covering material is called a foot cover or pad.

In addition, the binding B includes a high back B3 that supports the ankle and the calf, and a heel cup B4 that is placed under the high back B3 to secure the ankle and heel. The front side of the snow boots is covered and fixed around the ankle with an ankle strap B5 and around the toes with a toe strap B6. Note that the snowboard binding plate 1 according to the present invention may also be referred to as a center disk.

The snowboard binding plate 1 according to the present invention will be explained using FIGS. 2 to 8. Teeth (not shown) having fine irregularities are formed on the outer periphery of the center hole B2. The plate 1 has a ring 2, and the ring 2 has teeth 3 formed on its lower outer circumferential surface (bottom surface) for meshing with the teeth. A cup 4 is engaged with this ring 2. This cup 4 has a bottom part 4a forming its bottom surface, a side part 4b extending upward from the outer peripheral edge of this bottom part 4a, and a flange extending outward from the upper end of this side part 4b. 4c.

The plate 1 is fixed to the board body via screws 5. The screw 5 is inserted through a screw hole 6 provided through the bottom 4a of the cup 4, and is screwed into the board body. A case 7 is housed within the cup 4. An insertion hole 8 corresponding to the screw hole 6 is formed in the case 7, and the head of the screw 5 is disposed in the insertion hole 8. For example, when there are four screw holes 6 as shown in the figure, four insertion holes 8 are formed in the case 7 at the same positions.

As described above, according to the present invention, the case 7 is accommodated in the space within the cup 4 that constitutes the plate 1 that is accommodated in the base plate B1, which is the sole of the binding B, so that it can be accommodated in the space within the cup 4 that constitutes the plate 1 that is housed in the base plate B1 that is the sole of the binding B. Binding B is never processed. Therefore, a space can be formed in the board body and the binding B without affecting the operability and running performance of the snowboard, and the case 7 can be reliably accommodated in the space. In addition, since the case 7 is formed with an insertion hole 8 corresponding to the screw hole 6, the head of the screw 5 arranged in the screw hole 6 protrudes into the insertion hole 8 to fix the position of the case 7. This prevents the case 7 from rotating in the circumferential direction. At this time, if the screw hole 6 has a perfect circular shape, rotation of the case 7 as well as the cup 4 is suppressed. In other words, if the screw hole 6 has a perfect circular shape, the screw 5 will be securely fixed at the position of the screw hole 6, so the case 7 fixed by the screw 5 will also be securely fixed at that position. . The ring 2 and the cup 4 can be made of resin, metal, carbon material, or the like. Note that if the ring 2 and the cup 4 are made of different materials, for example, the ring 2 is made of resin and the cup 4 is made of metal (for example, titanium), these different materials can be locked together to form a plate. This is preferable because it provides better operability.

The bottom portion 4a has a flat region 9 with a flat surface extending in a circular shape from the center to a portion including the screw hole 6 (flat region 9 shown by a dotted line in FIG. 5). In other words, the flat region 9 does not have a groove-like shape with a bottom surface or a raised uneven shape, and has screw holes 6 that are through holes and holes 10 described later. There is only one. The entire bottom surface of the case 7 is also formed to be flat and flush. Therefore, when the case 7 is housed in the cup 4, the flat area 9 and the bottom surface of the case 7 are brought into close contact.

In this way, the flat region 9 disposed at the bottom of the cup 4 and the bottom surface of the case 7 are flush and in close contact with each other, so even if the plate 1 is pressed by being stepped on by a foot, the force is transferred to the flat surface. This can prevent the case 7 from being damaged as much as possible. Further, by providing the flat area 9, the case 7 does not wobble, and the height of the case 7 can be made approximately the same as the height of the side portion 4b, so that the space inside the cup 4 can be used efficiently.

On the other hand, a hole 10, which is a through hole, is arranged in the center of the bottom 4a of the cup 4. Due to the presence of this hole 10, the cup 4 can also be bent to some extent, thereby improving operability for the user. Further, at least one bridge portion 11 may be formed to cross this hole portion 10. That is, since at least one bridge section 11 is disposed, there are at least two holes 10. As is clear from FIG. 5, this example shows an example in which one bridge section 11 is branched in the middle, and therefore there are three holes 10. The bridge portion 11 may have a linear shape or may have a curved shape as in the example shown in the figure.

By providing such a hole 10, flexibility can be imparted to the plate 1 as a whole, and by providing a bridge section 11 here, a certain degree of rigidity can also be imparted. That is, the hole 10 alone is too soft and affects the operability, but by providing at least one bridge section 11, rigidity can be imparted, and operability that is neither too soft nor too hard can be provided. This contributes to the fact that even if a space for accommodating the case 7 is provided in the plate 1, the operability and running performance of the snowboard are not affected.

Further, the ring 2 has a convex portion 12 and a concave portion 13 formed in a continuous uneven shape in the circumferential direction. The convex portion 12 and the concave portion 13 are continuously formed from the upper surface to the inner surface of the ring 2.

By providing the convex portions 12 and the concave portions 13 in the ring 2 in this way, the ring 2 itself becomes easily twisted, and a certain degree of flexibility can be imparted to the plate 1. Therefore, just the right operability can be provided to the user. This contributes to the fact that even if a space for accommodating the case 7 is provided in the plate 1, the operability and running performance of the snowboard are not affected. Further, the presence of the convex portions 12 and the concave portions 13 allows the shape to change somewhat due to contraction during molding with a metal mold. This leads to improved productivity.

Further, on the upper surface of the ring 2 and on the outer peripheral edge side, a locking piece 14 projects upward. A notch 15 is formed on the outer peripheral edge side of the flange portion 4c of the cup 4 in a shape in which the locking piece 14 is accommodated.

As described above, since the locking piece 14 and the notch part 15 are formed on the outer peripheral edge side of the ring 2 and the flange part 4c, it is possible to provide a hole in the flange part 4c and fit the protrusion protruding from the ring 2 into the hole. It is possible to improve the strength. That is, it is not preferable to form such protrusions on a resin ring because it easily breaks and the strength is low. Further, since the locking piece 14 and the notch portion 15 are formed on the outer peripheral edge side of the ring 2 and the cup 4, machining is easy and this is preferable from the viewpoint of productivity. In addition, as shown in the figure, there is at least one locking piece 14 and notch 15 of a different size from the others (in the figure, there are four large locking pieces 14 and notches 15 every 90 degrees, and one large locking piece 14 and one notch 15 are arranged every 30 degrees in between. By providing 12 small locking pieces 14 and 12 notches 15 in the ring 2, positioning when the ring 2 and the cup 4 are engaged can be easily performed.

As is clear from FIG. 8, when the case 7 accommodates an acceleration sensor, rotation angle detection sensor, or speed sensor, a connector section 16 for external connection may be provided (for example, a USB connector). Further, in the present invention, the case 7 can also be used as an accessory case or a GPS device. When the cup 4 is attached to the board body, the head of the screw 5 protrudes upward from the bottom 4a, so the case 7 can be easily accommodated in the cup 4 by simply dropping the screw hole 6 into the screw hole 6. In this respect as well, it is easy to handle. Since the head of the screw 5 catches the screw hole 6 in the rotational direction, the case 7 will not rotate once it is accommodated. Therefore, even a sensor that is affected by the rotation of the case 7 (for example, a rotation angle sensor with respect to the direction of travel) can be housed in the case 7 and applied.
