Description

TECHNICAL FIELD

The present invention relates to an angle adjuster for a snowboard binder, and more particularly, to an angle adjuster for a snowboard binder in which an angle of a binder is adjusted without difficulty and the binder is conveniently coupled to or decoupled from the snowboard and is firmly assembled to the snowboard.

BACKGROUND ART

In recent years, snowboarding has become one of popular winter sports. The snowboarding is similar to skiing in that a rider rides a snowboard along a hill covered by snow. The snowboard is similar to a small surfboard or a large skateboard without wheels in terms of external appearance. A person who rides a snowboard (“snowboarder”) locates his/her feet on the snowboard in a direction perpendicular to a lengthwise direction of the snowboard. Like a ski, a snowboarder puts on special boots, which are fixed to the snowboard by a binding mechanism for safety of the snowboarder.
Generally, snowboarders put heir left foot in front of their right foot on the snowboard, and desire to adjust a binding installation angle depending on their snowboarding style, technical level and/or propensity. Also, some snowboarders desire to put their right foot in front of their left foot (so-called goofy style). To meet different snowboarding style, technical level or propensity of snowboarders, the binder is installed in the snowboard so that a snowboard may adjust an angle of his/her feet with respect to a lengthwise direction of the snowboard.
As shown in FIG. 1, in a conventional snowboard 16, a screw 18 which penetrates an adjusting disk 20 on an upper part of a binder 40 is locked to the snowboard 16 to thereby fixe the binder 40 to the snowboard 16. Uneven parts (not shown) which are shaped like a gear and mate with each other are provided on a lower surface of the adjusting disk 20 and an upper surface of the binder 40 to control a rotation of the binder 40. While the binder 40 is installed in the snowboard 16, the snowboarder fixes boots 22 to the binder 40 and then snowboards.
However, to adjust an angle of the location of the snowboarder's feet, he/she should unscrew the screw 18 as much as needed and holds the adjusting disk 20 upward to separate the adjusting disk 20 and the uneven parts of the binder 40 and then adjusts the angle of the binder 40. Then, the snowboarder puts down the adjusting disk 20 to mate the adjusting disk 20 and the binder 40 and then fastens the screw 18 to firmly mount the binder 40 on the snowboard 16. Thus, it takes much time to adjust the angle of the binder 40 and a tool is necessary to unscrew or fasten the screw 18. Also, if the angle of the binder 40 is adjusted in the foregoing manner, the snowboarder should rotate the binder 40 with one hand while holding the adjusting disk 20 with the other hand.

Prior to description, in several exemplary embodiments, like numerals refer to like elements with the same configuration which will be described in the first exemplary embodiment as a representative and other configurations which are different from those according to the first exemplary embodiment shall be described in other exemplary embodiments.
Hereinafter, an angle adjuster for a snowboard binder according to the first exemplary embodiment of the present invention will be described in detail with reference to accompanying drawings.
FIG. 2 is a perspective view of the angle adjuster for a snowboard binder according to the present invention. FIG. 3 is an exploded perspective view of the angle adjuster for a snowboard binder according to the present invention.
As shown therein, the angle adjuster for a snowboard binder according to the present invention includes a fixation member 110 which is fixed to an upper surface of a snowboard B; a binder 120 which is detachably assembled to the fixation member 110 to rotate; and a coupling member which is installed in an upper side of the binder 120 and is selectively coupled to the fixation member 110. The angle adjuster for a snowboard binder may further include a locking member 140 which is assembled to the binder 120 and fixes a location of the coupling member 130.
The fixation member 110 is shaped like a circular disk and has a first locking part 111 formed on a plate surface thereof. First projection pieces protrude from both sides of an upper edge of the fixation member 110 and second combination grooves 113 are formed in a vertical direction on an external side in a perpendicular direction of the first projection pieces 112. A lower groove 114 is formed in a lower edge of the fixation member 110 to communicate with the second combination grooves 113. The snowboard B is fixed to the fixation member 110 by a screw S penetrating a plate face of the snowboard B. The first locking part 112 includes a circular hole penetrating a center of the plate face. A diameter of an upper side of the first locking part 112 is large and a diameter of a lower part of the first locking part 112 is small and an internal surface of the first locking part 112 is inclined and a plurality of concave and convex parts is formed in a vertical direction in the inclined internal surface.
The binder 120 includes a base 121 which forms a through hole 123 on a center thereof to insert the fixation member 110 thereinto, a diaphragm 122 which is formed in a vertical direction in both sides of the base 121, first combination grooves 124 which are formed in a vertical direction in both sides of the through hole 123, upper grooves 125 which are formed in the upper edge of the through hole 123 and are connected to the first combination grooves 124, second projection pieces 126 which protrude from a lower edge of the through hole 123 in a perpendicular direction of the first combination grooves 124, a guiding groove 127 which is formed in a vertical direction in an internal surface of the diaphragm 122, and an extension groove 128 which is formed in a horizontal direction in an upper side of the guiding groove 127. A supporting shaft 122 a is formed in an upper side of the guiding groove 127 and a stopper 122 b protrudes from a lower side of the guiding groove 127.
The coupling member 130 includes a moving plate body 131 in which a projection 132 is formed in both sides thereof and is inserted into the guiding groove 127 of the binder 120 and is inserted between both diaphragms 122 of the binder 120.
The coupling member 130 further includes a second locking member 132 which is formed in a lower surface of the moving plate body 131 and mates with the first locking part 111 of the fixation member 110, and a handle 134 which is rotatably assembled to an upper surface of the moving plate body 131 and is folded. The second locking part 132 is shaped like a cone whose upper side is cut, and a diameter of an upper side of the second locking part 132 is large and a diameter of a lower side thereof is small. A plurality of concave and convex parts is formed in a vertical direction in an inclined external surface of the second locking part 132 to mate with concave and convex parts formed in the internal surface of the first locking part 111. Also, the moving plate body 131 preferably includes a transparent material so that a user examine a locking location of the second locking part 132 and the first locking part 111 of the fixation member 110 or to identify a scale of an angle formed in the base of the binder 120.
The locking member 140 includes a rotating part 141 which is rotatably assembled to a supporting shaft 122 a formed in the diaphragm 122 of the binder 120, an a pressing piece 142 which extends from the rotating part 141 and presses an upper side of the projection 132 of the coupling member 130.
If the fixation member 111 and the binder 120 include a synthetic resin to process and manufacture a light snowboard, the first projection pieces 112 and the second projection pieces 126 include a metal plate and are fixed to an upper surface of the fixation member 110 and a lower surface of the binder 120, respectively, to prevent the coupling area from being damaged by an external shock and prevent the binder 120 from being separated from the fixation member 110 fixed to the snowboard B.
Hereinafter, an operation of the angle adjuster for a snowboard binder according to the first exemplary embodiment will be described.
FIGS. 4 to 9 illustrate an assembly process of the angle adjuster for a snowboard binder according to the present invention.
While the fixation member 110 forming the first locking part 111 on its center is fixed to the snowboard B by the screw S penetrating the plate face of the fixation member 110 and the binder 120 having the base 121 forming the through hole 123 on its center is arranged in an upper side of the fixation member 110 as in FIG. 4, an angle of the binder 120 is adjusted so that the first projection pieces 112 of the fixation member 110 are inserted into the first coupling grooves 124 of the binder 120 and the second projection pieces 126 of the binder 120 are inserted into the second coupling grooves 113 of the fixation member 110. Then, if the fixation member 110 is inserted into the through hole 123 of the binder 120 and the binder 120 is rotated, the first projection pieces 112 formed in both sides of the upper side of the fixation member 110 are held to the upper grooves 125 formed in an upper edge of the through hole 123 of the binder 110 as in FIG. 6 and the binder 120 is rotatably assembled to the fixation member 110 to thereby adjust an installation angle of the binder 120.
The second projection pieces 126 protruding from both sides of a lower side of the through hole 123 of the binder 120 are inserted into the lower grooves 114 formed in a lower edge of the fixation member 110 and provide strong coupling force by a duplicate coupling structure. Thus, the binder 120 is prevented from being separated from the fixation member 110 by an external shock.
Particularly, if the first projection pieces 112 of the fixation member 110 penetrate the first combination grooves 124 of the binder 120 and are held in part to the upper grooves 125 as in FIG. 7, the coupling state of the binder 120 is unstable. However, as the second projection pieces 126 which are formed in a lower part of the through hole 123 of the binder 120 are held to the lower grooves 114 of the fixation member 110 in a location spaced from the first projection pieces 112, a strong coupling force is provided even if a part of the first projection pieces 112 is held to the upper grooves 125, and safety of the coupling state improves.
As in FIG. 6, the coupling member 130 is assembled to an upper side of the binder 120 and moves along the guiding groove 127 formed in a vertical direction in the both diaphragms 122 and is coupled to the fixation member 110 and controls a rotation of the binder 120. The coupling member 130 is coupled to the fixation member 110 if moved to a lower part of the guiding groove 127, and is decoupled from the fixation member 110 if moved to an upper part thereof. In a process of adjusting the angle of the binder 120, the coupling member 130 is located in the extension groove 128 formed in a horizontal direction in an upper side of the guiding groove 127 and is prevented from being coupled to the fixation member 110. Then, a user may adjust the angle of the binder 120 with both hands. A user moves the coupling member 130 by using the handle 134 installed and folded in an upper surface of the moving plate body 131 of the coupling member 130.
If a user adjusts the binder 120 to a desired angle by rotating the binder 120 and moves the coupling member 130 from the extension groove 128 to the guiding groove 127 and then in a lower direction as in FIG. 8, the second locking part 132 formed in a lower center of the coupling member 130 is inserted into the first locking part 111 of the fixation member 110 exposed through the through hole 123 of the binder 120. A diameter of an upper part of the first locking part 111 is large and a diameter of a lower part thereof is small and the first locking part 111 with the foregoing configuration is formed in the center of the fixation member 110. A diameter of a lower part of the second locking part 132 is small and a diameter of an upper part thereof is large, and the second locking part 132 with the foregoing configuration is shaped like a large cone with its upper side cut and is formed in the lower center of the moving plate body 131 of the coupling member 130. That is, the lower end of the second locking part 132 whose diameter is small is inserted into the upper side of the first locking part 111 whose diameter is large. Thus, even if the second locking part 132 is not accurately coupled to a coupling location of the first locking part 111, it is efficiently inserted thereinto. As a plurality of concave and convex parts is formed in the internal inclined surface of the first locking part 111 and the external inclined surface of the second locking part 132, the first locking part 111 mates with the second locking part 132 and controls the rotation of the binder 120.
As in FIG. 9, the rotating part 141 of the locking member 140 is rotatably assembled to the supporting shaft 122 a formed in the both diaphragms 122 of the binder 120. When the pressing piece 142 extending from a lateral side of the rotating part 141 rotates in a lower direction, the pressing piece 142 presses the coupling member 130 to the fixation member 110 of the binder 120 and prevents the coupling member 130 from being separated from the fixation member 110. The pressing piece 142 of the locking member 140 is guided by the stopper 122 b formed in the diaphragm 122 of the binder 120 to a location pressing the coupling member 130.
If the binder 120 assembled to the fixation member 110 and mounted in the snowboard B is to be disassembled, such disassembly process is performed in a reverse order of the foregoing assembly order. That is, the locking member 140 is rotated to release the coupling member 130. The coupling member 130 is separated from the fixation member 110 by using the handle 134 formed in an upper side of the coupling member 130. Then, the coupling member 130 is located to the extension groove 128 provided in the upper side of the guide groove 127. Then, the binder 120 is rotated to locate the first projection pieces 112 of the fixation member 110 in the first combination grooves 124 and to locate the second projection pieces 126 of the binder 120 in the second combination grooves 113 of the fixation member 110. If the binder 120 is held upward, the binder 120 is separated from the fixation member 110.
Hereinafter, an angle adjuster for a snowboard binder according to a second exemplary embodiment of the present invention will be described.
FIG. 10 is an exploded perspective view of the angle adjuster for a snowboard binder according to the second exemplary embodiment of the present invention. FIG. 11 is a lower perspective view of a fixation member and a coupling member of the snowboard binder according to the second exemplary embodiment of the present invention.
As shown therein, the angle adjuster for a snowboard binder according to the second exemplary embodiment of the present invention is different from the angle adjuster for a snowboard binder according to the first exemplary embodiment in that it includes a locking member 140′ which fixes a binder 120 to a fixation member 110 while the binder 120 is assembled to the fixation member 110 and its angle is adjusted.
That is, the fixation member 110 according to the present exemplary embodiment includes a first locking part 111 which is formed in an upper central part of the fixation member 110, first projection pieces 112 which protrude from both sides of an upper edge, and second combination grooves 113 which are formed in a vertical direction in an external side in a perpendicular direction of the first projection pieces 112. The fixation member 110 is fixed to a snowboard B.
The binder 120 includes a base 121 which forms a through hole 123 into which the fixation member 110 is inserted, a diaphragm 122 which is formed in a vertical direction in both sides of the base 121, first combination grooves 124 which are formed in a vertical direction in at least both sides of the through hole 123 to insert first projection pieces 112 of the fixation member 110 thereinto, and upper grooves 125 which are formed along an upper edge of the through hole 123 of the base 121 to move the first projection pieces 112 of the fixation member 110. The binder 120 is rotatably assembled to the fixation member 110.
While the coupling member 130 is inserted between the both diaphragm 122 of the binder 120, both sides of the moving plate body 131 are closely adhered to an internal surface of the diaphragm 122 to prevent a rotation of the coupling member 130. The coupling member 130 includes a second locking part 132 which is formed in a lower surface of the fixation member 110 and mates with the first locking part 111 of the fixation member 110 and is assembled to the fixation member 110 in an upper side of the binder 120.
In particular, the locking member 140 which fixes the coupling member 130 to the fixation member 110 includes a rotating shaft 143 which forms a coupling projection 143 a in both sides of a lower part thereof and a folding handle 143 b in an upper part thereof and is rotatably installed in a center of a moving plate body 131 of the coupling member 130, an insertion opening 144 which is shaped like a rectangle and is formed on a center of the fixation member 110 to insert the coupling projection 143 a of the rotating shaft 143 thereinto, and a space 145 which is formed in an internal area of the insertion opening 144 so that the coupling projection 143 a of the rotating shaft 143 rotates while being inserted into the insertion opening 144.
FIG. 12 is a lateral sectional view of an assembly state of the angle adjuster for a snowboard binder according to the second exemplary embodiment of the present invention. FIG. 13 is a plan sectional view of an assembly state of the angle adjuster for a snowboard binder according to the second exemplary embodiment of the present invention.
As shown therein, if the binder 120 is rotated while the fixation member 110 fixed to an upper surface of the snowboard B is arranged to be inserted into the through hole 123 formed in the base 121 of the binder 120, the first projection pieces 112 formed in both sides of the fixation member 110 are located in the upper grooves 125 formed in an internal circumference of the through hole 124 of the binder 120 and the binder 120 is rotatably assembled to the fixation member 110.
Then, a user adjusts the binder 120 to a desired angle and fixes the binder 120 to the fixation member 110 by using the coupling member 130 to thereby prevent the binder 120 from being rotated. The assembly structure of the second locking part 132 of the coupling member 130 and the first locking part 111 of the fixation member 110 is the same as that according to the first exemplary embodiment of the present invention. Thus, detailed description thereof will be omitted.
If the rotation of the binder 120 is restricted by the assembly of the coupling member 130 as above, the locking member 140′ is used to prevent the coupling member 130 and the fixation member 110 from being decoupled from each other.
Referring to the operation of the locking member 140′, a lower end of the rotating shaft 143 rotatably provided in a center of the moving plate body 131 of the coupling member 130 is inserted into the insertion opening 144 formed in a center of the fixation member 110 and is located in the space 145 inside the insertion opening 144 during a process of coupling the coupling member 130 to the fixation member 110.
A rotation angle of the rotating shaft 143 is adjusted so that the coupling projection 143 a formed in lower sides of the rotating shaft 143 penetrates the insertion opening 144 and is inserted into the space 145 through the insertion opening 144 during an assembly process of the coupling member 130 and the fixation member 110.
If the rotating shaft 143 is rotated by approximately 90 degrees by using the handle 143 b provided in an upper part of the rotating shaft 143 while the coupling projection 143 a is located within the space 145, the coupling projection 143 a in lower sides of the rotating shaft 143 is interfered with by a peripheral part on both sides of the insertion opening 144 and the coupling member 130 is prevented from being separated from the fixation member 110.
After the coupling member 130 is fixed to the fixation member 110, the handle 143 b formed in the upper part of the rotating shaft 143 is rotated to be arranged in parallel with the moving plate body 131 of the coupling member 130. Then, the handle 143 b is prevented from being interfered with by user's boots and the rotating shaft 143 is prevented from being rotated by the handle 143 b while in use.
The locking member 140′ may be released in a reverse order of the locking order. If the rotating shaft 143 is rotated by approximately 90 degrees to separate the coupling projection 143 a formed in the lower sides of the rotating shaft 143 upward through the insertion opening 144 in a rectangular shape, the coupling projection 143 at both sides conforms to the insertion opening 144 and the coupling member 130 may be separated from the fixation member 110.
Although a few exemplary embodiments have been shown and described, it will be appreciated by those skilled in the art that changes may be made in these exemplary embodiments without departing from the principles and spirit of the invention, the range of which is defined in the appended claims and their equivalents.
