Description

Sole buckle block for racing bicycle shoes

The present invention relates to a sole buckle block of a racing-type bicycle-specific shoe, and more particularly to a structural design of a non-slip cushion pad with a changeable sole buckle block.

Clipless pedals for bicycles require a buckle block that is fixed to the sole of the shoe to connect the shoe with the pedal buckle. It has multiple types to correspond to different riding styles, such as racing bicycles. For mountaineering and off-road vehicles.

The buckle block used in conventional racing bicycles is slightly triangular, and has three fixing holes arranged in a "pin" shape, and then three screws are passed through the fixing holes to lock the buckle block to the sole of the shoe. Then, the front and rear ends of the cleat block are used to buckle the front and back hooks of the pedal. Because the cleat block and the pedal surface are made of hard material, it is easy to slip when buckled, and the tolerance between the cleat block and the pedal surface may vary The gap is also prone to shake, so some people will protrude a non-slip cushion between the fixing holes to eliminate the clearance margin between the sole buckle block and the pedal and provide the anti-slip effect between the sole buckle block and the pedal. However, the anti-slip cushions are all protrusions of a single thickness, so they can only make contact with the pedal with a single protrusion size, which is a big regret.

Clearance margin and provide anti-slip cushioning strength between sole cleat block and pedal.

Another object of the present invention is to provide a sole buckle block of a racing bicycle shoe, which has a structural design that can adjust the tightness of the buckle block's anti-slip pad. When the thickness of the slip buffer thickness is used to a certain extent and the anti-slip cushion effect is affected, the thickness configuration of the anti-slip cushion can also be selected so that the anti-slip cushion can continue to be used to achieve the continuation of the anti-slip. The service life of the cushion.

In order to achieve the above object, the present invention is a shoe buckle block for a racing bicycle shoe, which includes a buckle block body, a non-slip cushion and a pad. The buckle block body is slightly triangular and has three A fixing hole arranged in a "pin" shape and a central perforation located between the three fixing holes, wherein one end of the central perforation toward the top surface has a recessed groove, and a front groove area is divided in front and rear directions. With a rear groove area, the central perforation is located in the front groove area. The anti-slip cushion is a sleeve body corresponding to the central perforation. You can choose to set it in the central perforation in different directions to produce two kinds of anti-slip cushion thickness. The pad is a shape corresponding to the recessed groove on the top surface of the central perforation, and can choose to abut the anti-slip cushion in different directions; thereby providing a variable-strength anti-slip cushion for the rider to choose or after abrasion Can continue to use the purpose.
