A spring member 6a that engages with the frame A and the frame 4A is provided. Then, when the rear foot kicks on the ice surface during skating or when a load is applied to the tip side 1a of the boot 1 during cornering, the boot 1 rotates around the hinge 5 and resists the force of the spring member 6a. Even if the heel portion 2B separates from the frame 4B, the bottom surface 3b of the blade 3 keeps in contact with the entire surface of the ice, so that the skating shoes can slide without weakening the kicking force on the ice, and the blade 3 The heel portion 2B separated from the frame 4B provided on the blade 3B is pulled back toward the blade 3 again by the spring member 6a.

[0003]

By the way, in the above-mentioned prior art, the heel portion of the mounting member provided below the rear end side of the boot and the frame are also used during the acceleration period in the forwardly inclined posture immediately after the start. Because of the separation, there was a problem in that the separation between the heel and the frame was temporarily suppressed during the start dash period, which was not suitable for the purpose of facilitating acceleration.

Therefore, according to the present invention, during the acceleration sliding immediately after the start, the operation of the clap mechanism is temporarily suppressed, and after the steady sliding is started, the clap mechanism is operated, and the acceleration sliding mode is switched to the normal sliding mode. It is an object of the present invention to provide a crap-type skate shoe that can be switched mechanically without requiring a skater to judge and operate.

[0005]

According to a first aspect of the present invention, a boot, a boot rotatably supported by a frame provided at one end of the blade and supported so as to be separated from the blade, and a boot are provided. In a clap-type skate shoe comprising a spring member that biases in a direction to pull back to the blade side, an engaging member is provided on the bottom surface of the boot, and a latch mechanism is detachably disposed between the engaging member and the blade. The distance between the boot and the blade is suppressed at the time of a start dash, and the boot and the blade are separated at the time of a steady run to make a clap function.

In the second invention, the latch mechanism has a stopper member fixed to an engaging member or a blade, and a tooth profile on one upper side and a lower surface slidably inserted into a through hole formed in the stopper member. A molded stepping member, and a locking portion having a tooth profile formed on the engaging member, wherein the tooth profile of the stepping member is engaged with the tooth profile of the locking portion, and the stepping is performed by moving the locking portion up and down. The member is advanced by a predetermined number to disengage the tooth profile of the stepping member from the tooth profile of the locking portion.

In the third aspect, either the step member or the tooth shape formed on the locking portion is provided at a position shifted by a half pitch from each other.
