Therefore, the engaging operation can be easily performed, and the mounting can be easily performed with good balance as a whole. With this, the mounting on the mountain climbing shoes is completed, and the mounting can be performed extremely easily.
[0013]
In addition, since the elastic band string is configured to penetrate behind the enlarged portion for retaining in the suspended portions on both sides of the upper heel holding chain, the extension portion behind the elastic band string is pulled strongly. Even so, the portion ahead of the enlarged portion does not move rearward through the suspended portion, so that the portion forward from the enlarged portion is not tightened. Therefore, in an attempt to make the state of holding the upper heel of the mountaineering shoes by the upper heel holding chain firmly and firmly tightened, the length from the enlarged portion to the enlarged portion near the tip of the extended rear portion is shortened to reduce the ankle. Even if both ends are locked at the front by using the string end fastening pieces, the upper side of the mountain climbing shoe is not strongly tightened due to the influence.
[0014]
Further, it is needless to say that the simple crampons of the present invention have spikes projecting from the lower portions of the heel plate and the front plate, so that the effect of preventing slipping on ice and snow and on muddy roads can be sufficiently exhibited. However, since the pins for preventing lateral displacement are raised on the upper surfaces of the heel plate and the front plate, there is no possibility that these pins may shift forward and backward or left and right during walking. Therefore, walking safety can be further ensured.
[0015]
Subsequently, when the both ends of the elastic band string are turned forward from their corresponding sides to the front of the ankle, and when the connecting means is used, the parts of the elastic band string that are turned forward of the respective ankles are elastically balanced in structure. Therefore, the connecting operation can be easily performed, and the mounting can be easily performed with good balance as a whole. With this, the mounting on the mountain climbing shoes is completed, and the mounting can be performed extremely easily.
[0016]
A second aspect of the present invention is the simple crampon according to the first aspect of the present invention, wherein the connecting means is a string end clip having a locking hole and a notched locking hole, wherein the locking hole is formed of the elastic band. One end of the cord can be inserted into the enlarged band to prevent it from falling off, and the notched locking hole can be inserted into and removed from the other end of the elastic band cord. It is constituted by a string end fastening piece which can be locked by a.
[0017]
Therefore, according to the second simple crampon of the present invention, when the both ends of the elastic band cord are finally connected in front of the ankle, the strap end clip at one end is grasped and the other end is enlarged. This can be done simply by simply inserting the front of the part into the notched locking hole of the string end clip from the notch. By the way, the end inserted into the notched locking hole is surely connected because the enlarged portion is locked in the portion of the locking hole.
[0018]
