Patent Application
20240216784
The present invention relates to a binding for a sliding board.
In the past, the snowboard binding disclosed in, e.g., Patent Document 1 was proposed for securing a boot to a snowboard.
The aforementioned snowboard binding comprises a foot-securing body 61 for securing a foot, and an attachment fixture 62 for attaching the foot-securing body 61 to a snowboard 50, as shown in
Because the angle at which the foot-securing body 61 is attached to the snowboard 50 differs according to the physique, skill level, and style of a snowboard rider, the attachment fixture 62 is configured to be fastened to the snowboard 50 via the screws 63 in a constant prescribed orientation and is provided with angle markings 64, and an inner peripheral part of the hole section 61a in the foot-securing body 61 is provided with an angle pointing part 65 for pointing to an angle marking 64. When the foot-securing body 61 is to be attached to the snowboard 50, adopting a state in which a desired angle of the angle markings 64 is pointed to by the angle pointing part 65 makes it possible to attach the foot-securing body 61 to the snowboard 50 at the desired angle.
However, when the angle at which the foot-fixing body 61 is attached to the snowboard 50 is to be adjusted after the foot-securing body 61 has been attached, all of the screws 63 are removed from the snowboard 50, the attachment fixture 62 is separated from the foot-securing body 61, and the angle between the foot-securing body 61 and the attachment fixture 62 (the angle at which the angle marking 64 is pointed to by the angle pointing part 65) is changed, after which the attachment fixture 62 is fastened to the snowboard 50 using all of the screws 63. In a scenario in which the angle at which the foot-fixing body 61 is attached to the snowboard 50 is frequently changed to correspond to numerous different people, such as at a rental shop for snowboards 50, it is highly inconvenient to rapidly adjust the attachment angle. The above-described structure is highly inconvenient not only when the angle at which the foot-fixing body 61 is attached to the snowboard 50 is adjusted indoors as described above but also when the attachment angle is adjusted outdoors (on a field for sliding).
Moreover, the binding for a sliding board disclosed in Patent Document 2 (referred to below as “prior-art example”) was proposed in the prior art as well, this binding being designed to enable the angle at which a foot-securing body 71 is attached to a snowboard 50 to be easily and quickly adjusted.
The prior-art example comprises a foot-securing body 71 for securing a foot, and an attachment fixture for attaching the foot-securing body 71 to a snowboard 50, as shown in
This configuration shall now be described in further detail. A pattern 72a of recesses and protrusions is provided to an outer peripheral surface of the disc body 72, and a pattern 71a′ of recesses and protrusions that engages with the pattern 72a of recesses and protrusions is provided to the inner peripheral surface of the hole section 71a in the foot-securing body 71. The hole section 71a in the foot-securing body 71 is configured to be non-rotatably fitted onto the disc body 72.
The restricting securing body 73 is composed of: a base member 73a configured to be screwed together with the disc body 72; and a ring member 73b provided to a lower-surface portion of the base member 73a so as to be capable of rotating relatively therewith about the same center of rotation. The ring member 73b is provided with a pattern 73b′ of recesses and protrusions that engages with a pattern 71a″ of recesses and protrusions provided to the periphery of the hole section 71a in the foot-securing body 71. When a handle 73a′ provided to the restricting securing body 73 is gripped and the restricting securing body 73 is rotated to be screwed together with the disc body 72, the ring member 73b is prevented from rotating due to the pattern 73b′ of recesses and protrusions in the ring member 73b catching and engaging with the pattern 71a″ of recesses and protrusions in the foot-fixing body 71. The base member 73a is configured to rotate until screwing concludes.
Therefore, in the prior-art example, the hole section 71a in the foot-securing body 71 is fitted onto the disc body 72 fastened to the upper surface of the snowboard 50, in which state the handle 73a is rotated to screw the restricting securing body 73 together with the disc body 72, whereby the foot-securing body 71 can be attached to the snowboard 50. During fitting of the hole section 71a in the foot-securing body 71 onto the disc body 72, the hole section 71a in the foot-securing body 71 is fitted onto the disc body 72 using the angle guide 75 on the foot-securing body 71 as an indicator for the angle markings 74 provided to the disc body 72, whereby the foot-securing body 71 can be attached at a desired angle to the snowboard 50.
Additionally, in the prior-art example, in a case where the angle at which the foot-securing body 71 is attached to the snowboard 50 is to be adjusted after the restricting securing body 73 has been attached, the handle 73a is rotated to remove the restricting securing body 73 from the disc body 72, the angle between the foot-securing body 71 and the disc body 72 (the angle at which the angle marking 74 is pointed to by the angle guide 75) is changed, and the handle 73a is rotated to screw the restricting securing body 73 together with the disc body 72, whereby the procedure concludes.
Because the restricting securing body 73 can be easily detached from the disc body 72 using an operation for rotating the handle 73a as described above, it is possible, in the prior-art example, for the angle at which the foot-securing body 71 is attached to the snowboard 50 to be easily and quickly adjusted.
However, in the prior-art example, the angle markings 74 are provided to an upper surface of the disc body 72, and because the angle markings 74 might be concealed when the restricting securing body 73 is screwed together with the disc body 72, a problem is presented in that, after the foot-securing body 71 has been attached to the snowboard 50 at a prescribed angle, the attachment angle cannot be confirmed unless the restricting securing body 73 is removed at each instance, thus making it impossible to confirm the current attachment angle at a glance.
The present invention was contrived in view of the above-described problem and provides an unprecedented and highly practical binding for a sliding board.

Preferred embodiments of the present invention are briefly described below with reference to the drawings while indicating the effects of the present invention.
In the present invention, when, for example, a hole section 2 in a foot-securing body 1 is fitted onto a disc body 11 fastened to an upper surface of a sliding board 50, the foot-securing body 1 is incapable of rotating relative to the disc body 11, in which state a restricting securing body 12 is linked to the disc body 11, whereby the foot-securing body 1 is attached to the sliding board 50.
If angle guides 3 of the disc body 11 are employed as an indicator for an angle display part 4 on the foot-securing body 1 when the hole section 2 in the foot-securing body 1 is fitted onto the disc body 11, a desired angle of the angle display part 4 for which the angle guides 3 are used as an indicator will be the angle at which the foot-securing body 1 is attached to the sliding board 50. Additionally, when the restricting securing body 12 is linked to the disc body 11, the desired angle of the angle display part 4 for which the angle guides 3 are used as an indicator when fitting the hole section 2 in the foot-securing body 1 onto the disc body 11 will be pointed to by an angle pointing part 5 provided to the restricting securing body 12.
When the angle at which the foot-securing body 1 is attached to the sliding board 50 is to be adjusted, the restricting securing body 12 is removed from the disc body 11 to separate the foot-securing body 1, the hole section 2 in the foot-securing body 1 is subsequently fitted onto the disc body 11 in consideration that the angle at which the foot-securing body 1 is attached to the sliding board 50 is to be a desired angle according to the main points described previously, and then the restricting securing body 12 is linked to the disc body 11.
According to the present invention, the angle at which the foot-securing body 1 is attached to the sliding board 50 can be perceived from external appearance, and it is not necessary to, inter alia, remove the restricting securing body 12, as in the prior-art example described previously, to recognize the attachment angle.
A specific example 1 of the present invention is described below with reference to the drawings.
The present example is a binding for a sliding board, the binding comprising a foot-securing body 1 for securing a foot, and an attachment fixture 10 for attaching the foot-securing body 1 to a sliding board 50.
The present example is applied to a snowboard that slides on the surface of snow, a snowboard boot worn by a snowboard rider being mounted on the foot-securing body 1, as the sliding board 50. However, the present example can also be applied to other structures, such as a snow ski, a wakeboard in which a foot is secured to a boot-shaped foot-securing body 1, or a water ski; other configurations can also be employed, as appropriate, provided that the features of the present example are exhibited.
Constituent portions according to the present example shall be described in detail below.
As shown in
The baseplate 1A of the foot-securing body 1 is provided with a hole section 2 that is circular in plan view.
The hole section 2 is formed passing through a central part of the baseplate 1A as shown in
An inner peripheral surface of the hole section 2 is provided with a jagged first pattern 6a of recesses and protrusions, in which acute peak-form protrusions and V-shaped recesses extend continuously with one another. When the hole section 2 is fitted onto the disc body 11, the first pattern 6a of recesses and protrusions engages with a second pattern 6b of recesses and protrusions provided to an outer peripheral end section of the disc body 11 to constitute a foot-securing-body-rotation-preventing part 6 for preventing the foot-securing body 1 from rotating relative to the disc body 11.
Adjacent protrusions in the first pattern 6a of recesses and protrusions are provided at angular intervals of 6°.
Therefore, when the hole section 2 in the foot-securing body 1 is fitted onto the disc body 11, the foot-securing body 1 is prevented from rotating by the foot-securing-body-rotation-preventing part 6. Moreover, rotating the foot-securing body 1 as appropriate in a state in which the foot-securing body 1 has been separated from the disc body 11 makes it possible to set the angle at which the foot-securing body 1 is attached to the sliding board 50 to a desired angle at six-degree intervals. This configuration may be modified such that the attachment angle can be set to angles at three-degree intervals or other intervals.
The periphery of the hole section 2 formed in the foot-securing body 1 (baseplate 1A) is also provided with a step part 1a that is annular in plan view (recessed step part), the step part 1a being provided in a connected row arrangement to the hole section 2 and being such that a securing member 14 of the restricting securing body 12 (described later) descends and is fitted thereinto.
Specifically, the step part 1a is composed of a horizontal bottom surface 1a″ that is continuous with the inner peripheral surface of the hole section 2, and an inner peripheral surface 1a′ formed extending upright from the bottom surface 1a″ to an upper surface of the baseplate 1A. The inner peripheral surface 1a′ of the step part 1a is configured to be downwardly inclined toward the hole section 2.
Therefore, a recessed site into which the restricting securing body 12 is fitted is formed in a tapered shape increasing in diameter toward the top, thus making it possible to satisfactorily perform an operation for fitting the restricting securing body 12.
The inner peripheral surface 1a′ of the step part 1a is also provided with a jagged third pattern 7a of recesses and protrusions, in which acute peak-form protrusions and V-shaped recesses extend continuously with one another. When the restricting securing body 12 is fitted into the step part 1a, the third pattern 7a of recesses and protrusions engages with a fourth pattern 7b of recesses and protrusions provided to an outer peripheral end section of the restricting securing body 12 (securing member 14) to constitute a rotation-preventing part 7 for preventing the securing member 14 from rotating.
Therefore, when the restricting securing body 12 is fitted into the disc body 11, the securing member 14 of the restricting securing body 12 is prevented from rotating by the rotation-preventing part 7.
In the present example, adjacent protrusions in the third pattern 7a of recesses and protrusions are provided at angular intervals of 3°. Furthermore, the third pattern 7a of recesses and protrusions is provided in a state of being separated from the first pattern 6a of recesses and protrusions in the hole section 2 with the bottom surface 1a″ of the step part 1a being interposed therebetween.
Additionally, the foot-securing body 1 is provided with the angle display part 4.
The angle display part 4 is configured such that when the hole section 2 in the foot-securing body 1 is fitted onto the disc body 11 (described later) using the angle guides 3 as an indicator, the angle of the angle display part 4 for which the angle guides 3 are used as an indicator will be the angle at which the foot-securing body 1 is attached to the sliding board 50.
Specifically, as shown in
In the present example, an auxiliary angle display part 8 is located inward from the angle display part 4 and is provided to the bottom surface 1a″ of the step part 1a.
The auxiliary angle display part 8 is configured such that when the hole section 2 in the foot-securing part 1 is fitted using the angle guides 3 provided to the disc body 11 as an indicator, the angle of the auxiliary angle display part 8 for which the angle guides 3 are used as an indicator will be the angle at which the foot-securing body 1 is attached to the sliding board 50.
Specifically, as shown in
Therefore, although it is also permissible to use only the angle display part 4 described previously, using the auxiliary angle display part 8 makes it possible to match an angle more accurately due to the auxiliary angle display part 8 being located at a position closer to the angle guides 3 than that of the angle display part 4.
The attachment fixture 10 is configured from: the disc body 11, which is fastened to the upper surface of the sliding board 50, the hole section 2 formed in the foot-securing body 1 being fitted onto the disc body 11; and the restricting securing body 12 that links to the disc body 11 via the hole section 2 in the foot-securing body 1 to restrict and secure the foot-securing body 1.
As shown in
Adjacent protrusions in the second pattern 6b of recesses and protrusions are provided at angular intervals of 6° such that the second pattern 6b of recesses and protrusions engages at a desired angle with the first pattern 6a of recesses and protrusions described previously.
The disc body 11 is also provided with an internal threaded part 11a (cylindrical threaded hole section) in the central section thereof. The internal threaded part 11a is configured such that an external threaded part 15a (bolt part) of the restricting securing body 12 (described later) is screwed together therewith.
The internal threaded part 11a is configured to be provided with a metal cylindrical member 11a′ having a threaded hole. When another sliding board 50 is overlaid on the sliding board 50 in a state in which the disc body 11 is attached, an upper end section of the cylindrical member 11a′ does not scratch the other sliding board 50 even if a sliding surface of the other sliding board 50 touches the cylindrical member 11a′ (the cylindrical member 11a′ is structured such that a chamfering or rounding process is implemented so that there are no angles at the peripheral edge of the upper end section) (refer to
Therefore, when the sliding board 50 is stored or transported in a state in which the disc body 11 has been attached to the sliding board 50, even if a plurality of sliding boards 50 are overlaid on one another, the sliding surface of the other sliding board 50 will be prevented from getting scratched.
A plurality of fastening holes 11b used when fastening the disc body 11 using screws 9 in screw holes 50a (insert holes) provided in the upper surface of the sliding board 50 are provided to the periphery of the internal threaded part 11a. The fastening holes 11b are configured to allow placement of a metal internal threaded member.
In the present example, the fastening holes 11b are set to a position, quantity, and form corresponding to a plurality of types of fastening methods that differ depending on the sliding board 50. Specifically, four long-hole-shaped fastening holes 11b and three circular fastening holes 11b are provided, and the fastening holes 11b are configured to correspond to: a type in which fastening is performed using the four long-hole-shaped fastening holes 11b and four screws 9; a type in which fastening is performed using two circular fastening holes 11b and two screws 9; and a type in which fastening is performed using two long-hole-shaped fastening holes 11b, one circular fastening hole 11b, and three screws 9. When fastening is performed using the four long-hole-shaped fastening holes 11b, the attachment position on the disc body 11 in a direction orthogonal to the longitudinal direction of the sliding board 50 can be changed as appropriate to adjust the center position of the foot-securing body 1 (the foot of a snowboard rider).
A locking protrusion rib 11b′ is formed on the inner surface of each of the fastening holes 11b. Lower surfaces of head parts of the screws 9, which contact the inner surfaces of the fastening holes 11b, are provided with engaging protruding ribs 9a for engaging with the locking protrusion ribs 11b′ when the screws 9 are fastened into the fastening holes 11b.
Therefore, when the screws 9 are screwed into the fastening holes 11b, the engaging protrusion ribs 9a engage with the locking protrusion ribs 11b′, making it possible to perform solid fastening such that loosening does not readily occur.
The disc body 11 is also provided with the angle guides 3.
As shown in
The angle guides 3 are configured such that when the disc body 11 is fastened to the sliding board 50, the angle guides 3 provided at opposing positions on the front and rear are provided in a state of facing the same direction as the longitudinal direction of the sliding board 50, and the angle guides 3 provided at opposing positions on the left and right are provided in a state of facing a direction orthogonal to the longitudinal direction of the sliding board 50, and such that when the hole section 2 in the foot-securing body 1 is fitted onto the disc body 11, the angle guides 3 will serve as indicators for the angle display part 4 and the auxiliary angle display part 8 described previously.
As shown in
Specifically, the base member 13 is a circular plate-form body formed using an appropriate metal member as shown in
Therefore, the restricting securing body 12 can be screwed together with the disc body 11 by being rotated.
As described previously, the restricting securing body 12 is not limited to a structure for rotating to thereby link to the disc body 11 (a screwed-together structure); for example, the restricting securing body 12 may have a “one-touch” structure in which a locking protuberance is made movable and then detachably linked through a restriction operation.
Additionally, an arch-shaped handle 16 is provided to an upper surface of the base member 13 so as to be capable of being raised and lowered.
Therefore, it is possible to grip the handle 16 to rotate the restricting securing body 12 when attaching to or detaching from the disc body 11. Moreover, the restricting securing body 12 can also be rotated using a tool (manual or electric screwdriver) by using a groove 15b (bit-fitting groove) in the head part of the threaded member 15. Reference symbol 16a refers to a pivot shaft about which the handle 16 pivots.
As shown in
The securing member 14 is provided with a hole 14b passing through a central section so as to enable the threaded member 15 provided to the base member 13 described previously to rotate.
Therefore, a part of the threaded member 15 where a thread groove has been formed will project outward in a central section of a lower surface of the restricting securing body 12, the thread groove formation part being the external threaded part 15a to be screwed into the internal threaded part 11a in the disc body 11.
An upper surface of the securing member 14 is provided with a recessed part 14′ into which the base member 13 is fitted and placed so as to be capable of rotating relatively therewith about the threaded member 15. The securing member 14 has an annular surrounding part 14a that surrounds the outer periphery of the base member 13 and is exposed as seen from the planar direction when the base member 13 has been fitted and placed. The angle pointing part 5 is provided to an upper surface of the surrounding part 14a.
As shown in
The peripheral end section on the lower surface of the securing member 14 (a position below the surrounding part 14a) is provided with the jagged fourth pattern 7b of recesses and protrusions, in which acute peak-form protrusions and V-shaped recesses extend continuously with one another. When the restricting securing body 12 is fitted into the step part 1a of the foot-securing body 1, the fourth pattern 7b of recesses and protrusions engages with the third pattern 7a of recesses and protrusions provided to the step part 1a to constitute the rotation-preventing part 7 for preventing the securing member 14 from rotating.
Adjacent protrusions in the fourth pattern 7b of recesses and protrusions are provided at angular intervals of 3° such that the fourth pattern 7b of recesses and protrusions engages at a desired angle with the third pattern 7a of recesses and protrusions described previously.
Therefore, when the restricting securing body 12 is fitted into the disc body 11 and rotated, the securing member 14 is prevented from rotating by the rotation-preventing member 7, only the base member 13 is rotated until screwing concludes, and a state in which the angle display part 4 is pointed to by the angle pointing part 5 is maintained. The securing member 14 is sandwiched between the base member 13 and the foot-securing body 1, whereby the securing member 14 also exhibits a function as a “washer.”
Reference symbol 17 refers to a C-shaped ring for preventing the threaded member 15 from falling out to fasten the threaded member 15.
Because the present example is configured as described above, the foot-securing body 1 is incapable of rotating relative to the disc body 11 when the disc body 11 is fastened to the upper surface of the sliding board 50 and the hole section 2 in the foot-securing body 1 is fitted onto the disc body 11 fastened to the upper surface of the sliding board 50. Screwing the restricting securing body 12 together with the disc body 11 in this state attaches the foot-securing body 1 to the sliding board 50.
If the angle guides 3 of the disc body 11 are employed as an indicator for the angle display part 4 and the auxiliary angle display part 8 of the foot-securing body 1 when the hole section 2 in the foot-securing body 1 is fitted onto the disc body 11, a desired angle of the angle display part 4 and the auxiliary angle display part 8 (the same angle) indicated by the angle guides 3 will be the angle at which the foot-securing body 1 is attached to the sliding board 50. Additionally, when the restricting securing body 12 is screwed together with the disc body 11, the desired angle of the angle display part 4 and the auxiliary display part 8 for which the angle guides 3 are used as an indicator when the hole section 2 of the foot-securing body 1 has been fitted onto the disc body 11 will be pointed to by the angle pointing part 5 provided to the restricting securing body 12 (securing member 14). Because the restricting securing body 12 is screwed onto the disc body 11 due to rotation of only the base member 13, and the securing member 14 is prevented from rotating, the pointing by the angle pointing part 5 is maintained.
Additionally, when the angle at which the foot-securing body 1 is attached to the sliding board 50 is to be adjusted, the restricting securing body 12 is removed from the disc body 11 to separate the foot-securing body 1, the hole section 2 in the foot-securing body 1 is then fitted onto the disc body 11 in consideration that the angle at which the foot-securing body 1 is attached to the sliding board 50 is to be a desired angle according to the main points described previously, and then the restricting securing body 12 is screwed together with the disc body 11.
In the present example, the angle at which the foot-securing body 1 is attached to the sliding board 50 can be perceived from external appearance, and it is not necessary to, inter alia, remove the restricting securing body 12, as in the prior-art example described previously, to recognize the attachment angle.
Thus, according to the present example, the angle at which the foot-securing body 1 is attached to the sliding board 50 can be quickly adjusted, and moreover, the angle at which the foot-securing body 1 is attached to the sliding board 50 can be confirmed at a glance from external appearance.
In the present example, because the angle display part 4 is located on the peripheral edge of the hole section 2 and is provided at a position where the angle display part 4 is not concealed by the restricting securing body 12, the effect described previously can be reliably realized.
Additionally, in the present example, because the restricting securing body 12 is composed of the base member 13 configured to be rotated to thereby link to the disc body 11, and the securing member 14 provided to the base member 13 so as to be capable of rotating relatively therewith about the same center of rotation, and because the securing body 14 is provided with the angle pointing part 5, the effect described above can be reliably realized with regard to this feature as well.
Additionally, in the present example, because the rotation-preventing part 7 for preventing the securing member 14 from rotating is provided between the securing member 14 and the foot-securing body 1 when the restricting securing body 12 is rotated and thereby linked to the disc body 11, the state in which the angle display part 4 is pointed to by the angle pointing part 5 can be maintained even when the restricting securing body 12 is rotated.
Additionally, in the present example, because the periphery of the hole section 2 is provided with the annular step part 1a into which the securing member 14 is fitted, and because the inner peripheral surface 1a′ of the step part 1a is configured to be downwardly inclined toward the hole section 2, the restricting securing body 12 can be satisfactorily fitted and placed relative to the foot-securing body 1.
A specific example 2 of the present invention is described below with reference to the drawings.
The present example is a binding for a sliding board, the binding comprising a foot-securing body 1 for securing a foot, and an attachment fixture 10 for attaching the foot-securing body 1 to a sliding board 50, wherein: the attachment fixture 10 is composed of a disc body 11 that is fastened to the upper surface of the sliding board 50, a hole section 2 formed in the foot-securing body 1 being non-rotatably fitted onto the disc body 11, and a restricting securing body 12 that links to the disc body 11 via the hole section 2 in the foot-securing body 1 to restrict and secure the foot-securing body 1; the periphery of the hole section 2 in the foot-securing body 1 is provided with an angle guide 34; the disc body 11 is provided with a first angle display part 33; the first angle display part 33 is configured such that when the hole section 2 in the foot-securing body 1 is fitted using the angle guide 34 of the disc body 11 as an indicator, the angle of the first angle display part 33 for which the angle guide 34 is used as an indicator will be the angle at which the foot-securing body 1 is attached to the sliding board 50; and the restricting securing body 12 is furthermore provided with a second angle display part 35 configured to display the same angle as the first angle display part 33 indicated by the angle guide 34.
Specifically, the foot-securing body 1 is provided with the angle guide 34, the disc body 11 is provided with the first angle display part 33, and the restricting securing body 12 is provided with the second angle display part 35. The angle guide and the angle display parts are thus provided in a relationship opposite that in embodiment 1 described previously.
As shown in
In the present example, an auxiliary angle guide 36 is located inward from the angle guide 34 and is provided to a bottom surface 1a″ of a step part 1a.
The auxiliary angle guide 36 is configured such that when the hole section 2 in the foot-securing body 1 is fitted onto the disc body 11 using the auxiliary angle guide 36 as an indicator, the angle of the first angle display part 33 for which the auxiliary angle guide 36 is used as an indicator will be the angle at which the foot-securing body 1 is attached to the sliding board 50.
Specifically, as shown in
Therefore, although it is also permissible to use only the angle guide 34 described previously, using the auxiliary angle guide 36 makes it possible to match an angle more accurately due to the auxiliary angle guide 36 being located at a position closer to the first angle display part 33 than that of the angle guide 34.
As shown in
As also shown in
Example 2 is otherwise similar to example 1.
The present invention is not limited to examples 1 and 2; the specific configurations of constituent elements in the present invention can be designed as appropriate.
