Description

  The present invention relates to a snowboard binding for attaching a boot to a board.

  As described above, the binding is for attaching the boot to the board. That is, it connects the foot and the board and is very important. Attaching this binding to an appropriate position according to the rider's physique, taste and level is called a setting, but until now there has been no real setting.

  The reason is the snowboard structure. That is, in the binding, a plurality of mounting screws 102 such as four, three, or two are attached to the disk-shaped disc plate 101 (see FIG. 9) that is fixed from above with respect to the base plate that forms the bottom of the binding. Are fixedly attached to the board 103, and a screw hole 104 for screwing the mounting screw 102 is provided on the upper surface of the board 103. The screw hole 104 is a length of the board 103. A plurality of sets of screw holes are arranged side by side, and the position in the length direction of the board, that is, the stance width is set depending on which of the plurality of sets of screw holes 104 is used to attach the binding. The In FIG. 9, the binding is not shown.

  The disk plate 101 is formed with a set of screw insertion holes 105 for inserting the mounting screws 102. This set of screw insertion holes 105 is naturally formed such that the center position P thereof coincides with the center position Q of the disk plate 101. And so that the position adjustment (centering) of the board 103 in the width direction can be performed, a plurality of screw insertion holes 105a constituting a set of screw insertion holes 105 are arranged in the same direction.

  Because of this configuration, the position and stance width in the length direction of the board 103 and the position in the width direction of the board 103 (centering) are determined by the combination of the screw insertion hole 105a of the disk plate 101 and the screw hole 104 of the board 103. ) And can be adjusted.

  However, in the case of a four-hole type that is fixed by four mounting screws 102, a set of screw holes 104 of the board 103 are arranged at intervals of, for example, 40 mm so as to draw a square. 103, the stance width is increased or decreased by 20 mm at a time when the mounting position of one of the two disc plates 101 corresponding to the left and right feet is shifted in order to adjust the stance width. Done. In this case, since only one of the disk plates 101 is moved, the center of gravity position of the rider is shifted from the center of gravity position G of the board 103.

  Therefore, if the center of gravity of the board is regarded as important and the two disk plates 101 and 101 are moved, the stance width will be changed by 40 mm.

  In order to eliminate such difficulties, it is conceivable to align the screw insertion hole arrangement direction of the disk plate 101 with the length direction of the board 103, but this causes a new problem that centering cannot be performed. Resulting in.

  Thus, it is difficult to make all of the stance width, the center of gravity, and the centering appropriate.

  Although snowboarding is a balanced sport, riding in the middle of a boat is the basis of snowboarding, and it is indispensable in terms of safety as well as improving the technology to suit the rider's personality. In general, only rough settings have been made, for example, “Regular angle 21 front, 6 stance 54 cm around”. As for the stance width, the basic stance width is 48-50 cm for girls and 53-55 cm for boys. From this figure, you can see the importance of changing the stance width by 40mm at a time.

  Another reason is that the boots are formed in 0.5cm increments, for example, and there are only three types of bindings, S, M, and L. It is mentioned that the M binding is used for the boots and the L binding is used for the boots around 28.5 cm. That is, when using boots of the above sizes, setting can be performed easily, but when using boots of other sizes, setting is complicated and difficult.

  In order to solve such problems, techniques such as Patent Documents 1 and 2 below have been proposed.

  These use a long hole so that the position can be adjusted continuously instead of the stepwise adjustment as described above.

  However, since the position can be adjusted using the long hole, another member is required on the disk plate or the board side in order to tighten the long hole portion, and the number of parts increases. As the number of parts increases, the weight increases accordingly, which hinders the competition.

  In addition, since a long hole is used, there is a possibility that the binding may be displaced due to an impact when dropping from a high place such as 10 m, which causes a problem in terms of safety.

  Further, since the position adjustment is performed continuously, it is difficult to perform setting once performed properly. It is absolutely impossible if the board changes. In other words, since there is no reproducibility, once a good setting can be made, it cannot be utilized at the next opportunity, and it is necessary to make a new setting again, which is troublesome.

  Accordingly, the main object of the present invention is to make it possible to perform appropriate settings suitable for each rider, to be lightweight, to have high safety, and to easily reproduce settings.

  Means for this is a disk plate for a snowboard binding having a plurality of screw insertion holes through which mounting screws are inserted, and the center position of the screw hole group consisting of the plurality of screw insertion holes is the center of the disk plate. This is a disk plate for a snowboard binding set at a position deviated from the position.

  The center of the screw hole group means a point that is equidistant from each screw insertion hole.

  That is, when attaching the binding, the mounting screw is inserted into the screw insertion hole of the disk plate and fixed to the board. At this time, the disk plate that can fix the binding at a desired position is positioned at the position of the screw insertion hole. Select based on and install. Since the center position of the screw hole group is deviated from the center position of the disk plate, the center position of the disk plate, that is, the center position of the binding can be fixed by being shifted from the center position of the plurality of screw holes used by a predetermined amount. This ensures the best settings for the rider.

  For example, if the bias is performed in units of mm, finer setting is possible.

  Another means is a disk plate for a snowboard binding having a plurality of screw insertion holes in which a plurality of screw insertion holes for inserting mounting screws are arranged in parallel, the screw hole comprising the plurality of screw insertion holes. This is a snowboard binding disk plate in which the center position of the group is set to a position deviated from the center position of the disk plate in a direction other than the length direction of the screw insertion hole.

  The center of the screw hole group refers to a point equidistant from the center position of each screw insertion hole.

  That is, when attaching the binding, the mounting screw is inserted into any of the screw insertion holes of the disk plate and fixed to the board. At this time, the binding may be fixed at a desired position. The disc plate that can be used is selected based on the position of the screw insertion hole, and then mounted. Since the center position of the screw hole group is deviated from the center position of the disk plate, the center position of the disk plate, that is, the center position of the binding can be fixed by shifting by a predetermined amount from the center positions of the plurality of screw holes used in the board. . This ensures the best settings for the rider.

  In addition, since a plurality of screw insertion holes are formed side by side, position adjustment in another direction such as centering can be performed with the same disk plate. For this reason, it is easy to select a disk plate, and it is possible to cope with changes in settings later.

  For example, if the bias is performed in units of mm, finer setting is possible.

  Moreover, the center position of the said screw hole group is good in the position biased in the width direction of the screw insertion hole part. Based on the value of the degree of deviation, that is, how many mm, the stance width can be adjusted in consideration of the center of gravity of the board, and the appropriate disk plate that ensures centering can be selected easily.

  The disk plate for the snowboard binding may be formed with a display portion for displaying numerically the deviation of the center position of the screw hole group. That is, it can be clearly shown how many mm the center position of the screw hole group is shifted in the width direction of the screw insertion hole. The presence of this display unit facilitates selection of an appropriate disk plate and provides reliable reproducibility.

  Another means is a snowboard binding provided with the above-mentioned snowboard binding disk plate.

  As described above, according to the present invention, the position and stance width in the board length direction and the position in the board width direction (centering) are determined by the combination of the screw insertion hole of the disk plate and the screw hole of the board. In addition to being adjustable, the mounting position can be adjusted more precisely by selecting the disc plate. In addition, since the position can be finely adjusted, the stance width can be adjusted in consideration of the center of gravity of the board. In other words, it is possible to make an appropriate setting that was impossible until now.

  And since the structure for that does not necessarily use an elongate hole, an additional member becomes unnecessary, it can prevent that a weight increases and can keep lightweight. In addition, since no long holes are used, there is no risk that the mounting screws will be accidentally displaced during competition, and safety can be obtained.

An embodiment for carrying out the present invention will be described below with reference to the drawings.
FIG. 1 is a perspective view of the board 11 and the binding 12, and the binding 12 is configured to be fixed at a desired position in both the length direction and the width direction of the board 11.

  That is, as shown in the figure, the binding 12 is fixed by attaching a disk-shaped disc plate 15 from above to a mounting hole 14 formed in the center of the base plate 13 which is the bottom of the binding 12. The disk plate 15 is fixed to the board 11 by using the mounting screws 16. At this time, a plurality of types of disk plates 15 that can fix the binding 12 at a desired position are selected and used.

  The mounting hole 14 is formed on an inclined surface that spreads toward the upper surface side, and a large number of gear-like irregularities are formed on the inclined surface. Yes. On the other hand, the disk plate 15 attached to the attachment hole portion has a size corresponding to the attachment hole portion 14, the lower surface side of the outer peripheral edge portion is formed in a tapered shape, and a number of unevennesses corresponding to the unevenness are formed. . The attachment angle (angle) of the binding 12 on the board 11 can be set by the engagement of the irregularities.

First, the board 11 will be described.
As shown in FIG. 1, the board 11 has a plurality of screws 16 to which the mounting screws 16 are screwed so that the binding 12 can be fixed at a position where the two left and right feet are placed as shown in FIG. A screw hole 17 is formed. FIG. 2 is a plan view showing a state where the disk plate 15 is placed on the board 11 and binding is omitted for convenience.

  The screw hole 17 is formed by embedding a nut. The four mounting screws 16 to be screwed into the screw holes 17 are used as described above, and are arranged so as to form four vertices of a square. Therefore, the screw holes 17 are formed in the middle of the board 11 in the width direction. It is formed by sorting left and right around the position. The interval between the screw holes 17 arranged in the length direction of the board 11 is set to a value half the interval in the width direction of the board 11. As shown in FIGS. 2 and 3, when five boards 11 are arranged in the length direction, four fixed patterns are obtained.

Next, the disk plate 15 will be described.
As shown in the plan view of FIG. 4, the disk plate 15 has four screw insertion holes 21. As shown by the alternate long and short dash line, these screw insertion holes 21 are arranged so as to draw a square when connecting four points at the center position.

  The four screw insertion holes 21 are formed in a vertically long linear shape in the drawing, and are arranged in two rows in the vertical and horizontal directions so that they can be attached to the screw holes 17 of the board 11.

  Each screw insertion hole portion 21 includes a plurality of screw insertion holes 22. Each screw insertion hole 22 inserts and holds the mounting screw 16 and is formed continuously, and has an arcuate edge at the inner peripheral edge so that the mounting screw 16 inserted and held is not displaced. A plurality of are formed.

  In this example, the screw insertion holes 22 are continuous. However, the screw insertion holes 22 may be independent and non-continuous.

  The four screw insertion holes 21 are in a state in which the center position P of the screw hole group which is a set of these is offset by a predetermined width W from the center position Q of the disk plate 11 in the width direction of the screw insertion holes 21. Formed to be. In other words, each screw insertion hole 21 is formed with a predetermined width W shifted from the original position in the width direction of the screw insertion hole 21.

  The center position P of the screw hole group is a point equidistant from the center position in the length direction of each screw insertion hole portion 21.

  The predetermined width W is set narrower than the interval between the screw holes in the length direction of the board 11. For example, a plurality of types having different values of the predetermined width W are set, such as 1 mm, 2 mm, 5 mm, and 10 m. A display portion 23 indicating the value of the predetermined width W is formed on the surface of the disk plate 15 as shown in FIG. The display unit 23 can be formed by appropriate means such as stamping, molding, and printing.

  A plurality of types of disk plates 15 are prepared in which the center position P of the screw hole group is shifted by a predetermined width W from the center position of the disk plate 15, and is prepared for the setting of the binding 12.

Setting is performed as follows.
First, the rider's stance width Ls is measured as shown in FIG. Next, based on the stance width Ls, the center position 15a of the two disk plates 15 in the length direction of the board 11 is specified while considering the center of gravity G of the board 11, and the disk plate 15 is fixed. The position of the screw hole 17 used for the above is specified. In the figure, a screw hole 17 indicated by a bold line is the specified screw hole 17.

  Of the identified screw holes 17, the difference between the middle positions S1 and S2 of the two screw holes 17 arranged in the length direction of the board 11 and the center position 15a where the disk plate 15 should be identified previously is different. The disk plate 15 having a deviation (the predetermined amount W) corresponding to the difference is selected, and the binding 12 is fixed by the four mounting screws 16 while performing centering using the disk plate 15. .

  FIG. 5 is an enlarged view showing part a of FIG. 2. As shown in FIG. 5, the mounting position of the disk plate 15 is the original mounting position indicated by the phantom line (the center position P of the screw hole group is The mounting position when it coincides with the center position Q of the disk plate 15 (the same applies hereinafter) is shifted in the length direction of the board 11 by a predetermined width W. That is, the attachment position of the binding 12 can be shifted. Moreover, although the broken line shows the attachment position to the adjacent screw hole 17, it can be seen that finer adjustment can be made. Furthermore, even if one disk plate 15 is used by being inverted 180 degrees, it can be fixed at the position indicated by the alternate long and short dash line, so that the position can be shifted by a predetermined width W to the opposite side from the original position.

  Referring to FIG. 2, when the stance width at the original mounting position is (L), the stance width of (L + W × 2) can be obtained without changing the center of gravity G. Since (W × 2) is set to 1 mm, 2 mm or the like as described above, fine adjustment can be freely performed.

  For this reason, the best setting suitable for the rider is possible.

  In addition, since a plurality of screw insertion holes 22 are formed side by side, centering can be performed with the same disk plate 15. Further, the center position P of the screw hole group is a position biased in the width direction of the screw insertion hole portion 21. For this reason, when selecting the disk plate 15, it is only necessary to consider the stance width Ls, the center of gravity G of the board, and the positions of the screw holes 17, the work is easy, and it is possible to easily cope with subsequent changes in settings.

  In addition, since the display unit 23 for displaying the bias numerically is formed, it is easy to select an appropriate disk plate 15 and reliable reproducibility is obtained. This reproducibility is excellent reproducibility, as long as the disk plate 15 can be mounted, the same mounting state can be obtained even if the board 11 is changed.

  Since such an effect can be obtained, the disk plate 15 and the binding 12 having the disk plate 15 are suitable for use at a snowboard store or a snowboard rental store at a ski resort, and have a disk plate suitable for the user. If so, the optimum setting can be easily performed at any time.

  FIG. 6 shows another example of how to attach the disk plate, in which the length direction of the screw insertion hole 21 is matched with the length direction of the board 11 and the deviation of the disk plate 15 is used for centering. That is, the disk plate 15 can be shifted by a predetermined width W in the width direction of the board 11. As a result, the binding 12 can be fixed at a desired position in both the length direction and the width direction of the board 11.

  7, 8, and 9 are examples showing a disk plate 15 that is fixed by three mounting screws 16. In addition, about the site | part same or equivalent to the above-mentioned structure, the same code | symbol is attached | subjected and the detailed description is abbreviate | omitted.

  That is, as shown in FIG. 7, the board 11 has a plurality of screw holes 17 formed in the length direction of the board 11, which are formed at positions that form three vertices of an equilateral triangle. In the illustrated example, four along the length direction are arranged in the center in the width direction of the board 11 and two on the left and right sides, and a total of eight screw holes 17 are provided. It is formed so that four different fixed patterns can be obtained.

  On the other hand, the disk plate 15 is provided with three vertically long screw insertion holes 21 having the same configuration as described above. Two of these are arranged on one side and one on the other side, and the three points at the center position of each screw insertion hole 21 are arranged so as to draw an equilateral triangle as shown by a one-dot chain line. The center position P of each screw insertion hole 21 is set at a position deviated from the center position Q of the disk plate 15 by a predetermined width W in the width direction of the screw insertion hole 21.

  The disk plate 15 configured in this way is also fixed in the same manner as described above, and the binding 12 is attached.

  FIG. 8 shows an example of attachment using the disk plate 15, where the phantom line indicates the original attachment position of the disk plate 15, and the broken line indicates the fixing position with respect to the adjacent screw hole. When the stance width at the original mounting position is (L), the stance width of (L−W × 2) can be obtained without changing the center of gravity G. Since (W × 2) is set to 1 mm, 2 mm or the like as described above, fine adjustment can be freely performed.

  In such a three-hole disk plate 15, when the disk plate 15 is rotated 180 degrees and fixed to the screw hole 17 of another pattern, or the two disk plates 15 are replaced and fixed, 1 The other disk plate 15 can be provided with other mounting modes.

  FIG. 9 shows an example in which the bias direction of the disk plate 15 is used for centering by adjusting the length direction of the screw insertion hole 21 to the length direction of the board 11 as in the case shown in FIG. . That is, the disk plate 15 can be shifted by a predetermined width W in the width direction of the board 11. As a result, the binding 12 can be fixed at a desired position in both the length direction and the width direction of the board 11.

The above is one form for implementing this invention, and another form can also be employ | adopted.
For example, the deviation of the center position of the screw hole group can be shifted not only in the width direction of the screw insertion hole portion but also in an oblique direction.
In addition, each screw insertion hole may be configured with one screw insertion hole.
