Description

[Detailed Description of the Invention] <Industrial Field of Application> The present invention relates primarily to improvements in cycling shoes worn during cycling events.

<Prior art and its problems> Bicycle shoes include so-called leisure cycling shoes, which are usually used for leisure, and cycling shoes for competitions. In such competitive bicycle races, the competition is for 0.01 seconds, so special measures are taken to suppress the energy loss of the athletes and to maximize the transmission of kinetic energy through the rotational force of the pedals. . In other words, the bar of the bicycle pedal should be able to engage with the plug on the sole of the shoe in a way that suits the rider's preference or fits the frame of the foot, and furthermore, once the pedal position is determined, it can be firmly fixed without slipping while riding. is considered to be an essential requirement, and in the past several bicycle shoes have appeared that meet these requirements. However, none of them has been found to completely satisfy these requirements, and there is still plenty of room for improvement. For example, there is a known bicycle shoe as shown in FIGS. 9 and 10. In such conventional products, a groove into which the pedal bar is fitted is bored across the center of the plug from side to side, and one vertically elongated through hole is provided on each of the upper and lower sides of the plug, separating the groove from the groove. On the other hand, two supporting parts for attaching the plug are buried and fixed on the ground side of the sole of the shoe. In such known examples, the permissible range in which the plug can be moved and adjusted is limited to the vertical direction, and sliding in the left and right directions, that is, the angle adjustment centering on the vertical direction of the plug, is not possible, and furthermore, the plug is only two pieces. Since it was supported by screws, it had a drawback of weak supporting force.

<Means for Solving the Problems> In view of the deficiencies of the conventional products mentioned above, the present invention is constructed as follows in order to overcome them. That is, in a bicycle shoe consisting of a shoe sole that is equipped with a bicycle plug that is attached to the ground surface side of the shoe sole and its attachment parts, the bicycle plug is attached to the approximately central side in the left-right direction that intersects with the front-rear direction. A groove into which a bicycle pedal bar is fitted is bored, one vertically elongated through hole is provided on the upper center side across the groove, and two vertically elongated through holes are similarly formed on the lower side across the groove. The holes are arranged in parallel, and on the other hand, the attachment component includes a single support component embedded and fixed in a part of the front stepping part on the ground-contacting surface side of the sole, and a single support component embedded and fixed in a part of the front tread part on the side of the ground contact surface of the sole, and , a plate having a guide groove curved in a concave arc shape is attached, and two supporting parts slide along the guide groove, and the bicycle plug is provided on the sole of the shoe. A new configuration was adopted in which the parts were attached and connected via screws.

<Function> Therefore, according to the present invention, the vertically long 3
The vertical movement of the plug itself can be adjusted using two through-holes and supporting parts.On the other hand, two through-holes provided at the bottom of the plug and a plate embedded in the ground surface of the sole of the shoe make it possible to adjust the movement of the plug itself in the vertical direction. The support member slides within the concave arc-shaped guide groove, thereby allowing the plug to move in the left-right direction.

<Example> The present invention will be explained below according to the embodiment shown in the drawings. Fig. 1 shows a plan view of a bicycle plug A attached to the ground surface of the sole of the present invention, and shows the front and rear views. A groove 1 into which the bar of a bicycle pedal is fitted is provided at approximately the center side in the left-right direction intersecting the direction, and one vertically elongated through hole 2 is provided at the upper center side across the groove 1, and Similarly, two vertically elongated through holes 2, 2 are arranged in parallel on the lower side with the groove 1 in between. At this time, each through hole 2 forms a stepped portion 8 that locks the head 7 of the screw 6, as shown in FIG. Further, the back surface of the plug A is formed into a curved surface so as to follow the ground contact side of the shoe. The plug A is usually made of a material such as plastic or hard synthetic resin that is resistant to abrasion and impact. Next, FIGS. 3 to 6 show a mounting part B to be attached to the ground side of the sole of the shoe, and three supporting parts 3, 4, 4 corresponding to the joint part of the plug A. FIG. 3 shows a single support part 3 embedded in a position corresponding to the through hole 2 above the plug A, and a screw 6 shown in FIG. A female thread is carved into the male thread.

As shown in FIG. 7, the support component 3 is embedded and fixed so that the upper edge 11 of the cylindrical portion 10 is substantially parallel to the ground surface of the sole of the shoe. FIG. 4 shows two supporting parts 4, 4 corresponding to the through holes 2, 2 on the lower side of the plug A. The seat plate 9 is formed into a substantially semicircular shape.
A cylindrical body 10 is provided to protrude above. The cylindrical body 10
There is also a female screw carved inside. FIG. 5 shows a plate C into which the two supporting parts 4, 4 shown in FIG. 13
, and a guide groove 5 curved in a concave arc shape is formed on the upper side of the lid body 12. As shown in FIG. 7, the guide groove 5 is formed in an arcuate curved shape that coincides with a portion of a rotating ring whose radius is a length F that connects the buried position of the single support component 3 described above. The plate C may be made of a lightweight metal plate such as aluminum alloy, or may be made of impact-resistant synthetic resin. FIG. 6 shows a state in which the supporting parts 4, 4 are loosely fitted into the plate C. It should be noted that the supporting parts 4, 4 do not necessarily need to be formed with the cylindrical part 10, and it is sufficient if the screws 14 are directly carved into the seat plate 9.

<Effect of the invention> Therefore, since the present invention has the above-mentioned configuration, the seventh
As shown in Fig. 8, the plug A is capable of sliding vertically within the permissible vertical width of each vertically long through hole 2, and fits into the plate C buried in the ground surface of the sole of the shoe. The supporting parts 4 and 4 not only allow the plug A to slide to the left and right, but also
The guide groove 5 provided on the upper surface of the plate C has an arcuate curve that matches a part of a rotating wheel whose radius is the length connecting the single support part 3 buried in the center side of the ground contact surface of the sole. As a result, the plug A can be rotated about the single support part 3 as a fulcrum, and the angle of the plug can be adjusted more smoothly. Furthermore, since the plug A is configured to be supported at so-called three points by three screws 6, there is an advantage that the fixing force of the plug A can be utilized to the maximum. Therefore, in view of the above-mentioned points, the present invention is extremely practical as a shoe for bicycle racing.
