Description

[Detailed description of the device]

[0001]

[Technical field to which the device belongs]

 The present invention relates to a skate blade fixing plate unit that is attached to the bottom of a skate and used to fix the skate blade, and in particular, the position of the skate blade that suits the conditions of one's foot and sole, The present invention relates to a fixing plate unit for a skate blade whose angle can be freely adjusted.

[0002]

[Prior art]

 As shown in FIG. 1, the conventional fixing plate unit for a skate blade normally serves as an intermediate medium when the skate blade a is attached to the skating shoe b, and usually has a metal fixing plate c and a synthetic resin bracket d. It is composed of As shown in FIG. 2, the conventional fixing plate unit has a bolt e embedded in the fixing plate c so as to be exposed downward. The bolt e is inserted into the horizontal portion f of the bracket d through a horizontally elongated hole g, and a nut k is used. Tighten and tighten the nut to the tip lead part of the bolt e that appears under the horizontally elongated hole g to fix the bracket d, and cover the vertical part h of the bracket d with the two holders fixed to the upper side of the skate blade. After the fastening hole i of the vertical portion h is aligned with the fastening hole on the flange side of the holder, the skate blade is fixed with a rivet or bolt.

[0003]

[Problems to be solved by the device]

 By the way, in the above-mentioned prior art, the bracket d has a leg of a person who prefers skating to have a straight leg, an O shape, a leg with an inward bent knee, or the size of the leg, or the habit of using skates. This is because the force applied to the front heel and the rear heel is adjusted to the condition by holding the skate blade a so that it exactly matches the center of the holder.

However, in the conventional bracket d, the width of the laterally elongated hole g is substantially equal to the thickness of the bolt e, and there is no margin for change in the width direction, that is, the front-rear direction. Therefore, the change can be made only on the left and right sides. It was It is difficult to accurately determine the angle of the skate blade a and the position of the power point of the sole by only moving the bracket d from side to side.

Further, the bolt e embedded in the fixed plate c also has a problem. Since the bolt e is long, the length of the vertical portion h of the bracket d tends to be naturally long. If the vertical portion h is long, the height of the skate blade holder, and thus the height from the skate blade a to the bottom leather of the skates b is limited.

Therefore, according to the present invention, the angle of the skate blade a and the position of the point that receives the force of the sole can be adjusted in all directions, a sense of stability can be obtained, and the installation height of the skate blade a is low. It is an object of the present invention to provide a fixing plate unit for a skate blade having a bracket that operates.

[0007]

[Means for Solving the Problems]

 To this end, the present invention has a fixing plate that leaves a room to reduce the length of the bolt by embedding a nut in the place where the bolt is provided, and an extension that extends the existing horizontal part to the opposite side of the vertical part. It consists of a bracket that keeps the horizontal part and resists the external force acting in the vertical direction on the vertical part, and a cam plate that can change the position and posture in all directions.

[0008]

BEST MODE FOR CARRYING OUT THE INVENTION

 Next, the present invention will be described in detail with reference to the accompanying drawings of FIGS. The fixed plate unit is composed of a fixed plate 10, a bracket 20 and a cam plate 30. The fixing plate 10 is made of aluminum and is a die-cast product, and the nut 11 is embedded in the place where the conventional bolt is provided.

The bracket 20 is made of synthetic resin, and an extended horizontal portion 21b extending from the existing horizontal portion 21a to the opposite side of the vertical portion 22 is combined so that it looks like a T-shape as a whole. In this way, even if the extended horizontal portion 21b is added to the horizontal portion 21a and an external force acts on the surface from the vertical portion 22 in any direction, the horizontal portion 21a or the extended horizontal portion 21b placed on the opposite side of the vertical portion 22 does not move. With sufficient durability, the mounting posture of the bracket 20 on the fixed plate 10 is further stabilized.

The horizontally elongated hole 23 also extends to the extended horizontal portion 21b. In addition, the width is increased and a step portion 24 is formed on the lower edge along the contour of the laterally elongated hole 23. The stepped portion 24 is provided with a stepped portion 33 formed around a cam plate 30, which will be described later, hooked on the cam plate 30 to prevent the cam plate 30 hooked in the horizontally elongated hole 23 from being pulled out upward.

A cam 31 is formed on the upper surface of the cam plate 30. This cam 31 is loosely sandwiched in the oblong hole 23 of the bracket 20 or is exactly sandwiched, and a shaft hole 32 is formed at a fulcrum deviating from the rotation center. After the bolt 40 is fitted in the shaft hole 32, its tip is fastened to the nut 11, and the bracket 20 and the cam plate 30 are fixed to the fixed plate 10. Further, a recess is formed at the lower edge of the shaft hole 32 so that the head of the bolt 40 can be covered.

[0012]

【Example】

 Hereinafter, the assembling of the fixing plate unit for the skate blade of the present invention will be described in detail. The bolt 40 in the present invention has a wrench groove on its head that can be turned with an L wrench. In order to lower the height of the vertical portion 22, the tool for operating the cam plate 30 should be a wrench with a thin thickness above all, but the head of the bolt should not protrude to the lower surface side against which the wrench hits. This is the reason why the concave portion is formed at the lower edge of the shaft hole 32 so that the head of the bolt 40 can be hooked there.

A plurality of pin holes 34 are formed on the lower surface of the cam plate 30 so as to be located on a single circumference. A pin of a wrench is inserted into the pin holes 34 to twist the cam plate 30. Pre-twisting allows the wrench to twist the cam plate 30 at any time, regardless of where the cam plate 30 rests in the pin hole 34, so that the wrench pin is inserted. When this point is taken into consideration, it is preferable to form a pin hole 34 for each fulcrum when drawing a diagonal line, a regular triangle, a regular quadrangle, or a regular hexagon on one circumference.

In the present invention constructed as described above, the fixing plate 10 is attached to the bottom leather of the skate with the nut 11 facing upward, or the fixing plate 10 is placed on the bottom leather and the middle leather or the middle leather. To fix.

Next, with the cam 31 placed on the upper side, the cam plate 30 with the bolt 40 placed on the lower side of the shaft hole 32 is assembled to the bracket 20. At this time, the cam 31 is fitted in the horizontally elongated hole 23, and the step portion 33 of the cam plate 30 is misaligned with the step portion 24 around the horizontally elongated hole 23 of the bracket 20.

Next, the tip of the bolt 40 protruding above the shaft hole 32 is fastened to the nut 11 of the fixed plate 10. Therefore, the fixing plate unit is completely attached to the skates, and then the skate blades 50 are attached by the conventional method.

When the angle and position of the skate blade a erected on the vertical portion 22 of the bracket 20 is unsuitable for one's foot and sole structure, loosen the bolt 40 slightly and loosen the cam plate 30 with a wrench. After twisting and adjusting the position of the bracket 20 to suit one's physical condition, the bolt 40 is tightened to fix the bracket 20 and the cam plate 30.

[0018]

[Effect of device]

 As explained above, according to the present invention, the position and angle of the skate blade a can be adjusted extremely easily by twisting the cam plate 30 according to the physical condition regardless of the condition of the foot and the sole of the foot. In addition, the length of the bolt 40 can be shortened by tightening so that the head of the bolt 40 is hidden behind the recessed shaft hole 32, so that when the cam plate 30 is twisted with a wrench, the bolt 40 can be shortened. The height of the wrench can of course be lowered, so that the height of the horizontal part, and thus the height of the skates can be lowered. This helps improve the record for long-track ice players. In addition, since the horizontal portions 21a and 21b of the bracket 20 are formed on both sides of the vertical portion 22 centering on the vertical portion 22 to play a role of increasing the force, the vertical portion 22 can withstand the lateral force acting. As the horizontal portions 21a and 21b are expanded, the thickness of the horizontal portions 21a and 21b can be reduced and the height of the skates can be further lowered. After all, if skates to which the present proposal is applied are used, the skating blade a is always kept at an appropriate angle due to the posture of the foot even at speed acceleration and cornering, which contributes to record improvement.
