Abstract
Disclosed are chain-type crampons for preventing mountain-climbing boots from being slipped on a snowy road or icy road when climbing a mountain. The crampons having an elastic band and chains mounted on the band are provided with a plurality of spikes and link rings including an advanced spike on the front of the boot when so mounted, so that a brake power on the snowy road or icy road is increased and snow is not adhered to the crampons. The crampons have a restraining member at the front.

- lateral spikes disposed forward between the front spike and the center spike, wherein the front spike, center spike, rear spike and lateral spikes are each operatively engaged to the chain via coupling rings;
- link rings each engaged to the front spike, the lateral spikes, and the center spikes;
- and a restraining member operatively coupled to the advanced front spike, the restraining member being engaged with a front of the boots when the elastic band is bound around the outsole of the boots.
Chain-type crampons provided with spikes in which an elastic band is adapted to be bound around an upper portion of an outsole of mountain-climbing boots and extend from a front portion to a rear portion of the boot when bound around the boot, and chains are coupled to the band as an anti-skid member, the crampons comprising:
- a plurality of spikes that are operatively coupled to the elastic band via chains and positioned to be disposed at an advanced front portion, a front portion, a center portion, a rear portion, and both sides between the front portion and the center portion on a bottom surface of the boots when the elastic band is bound around the outsole of the boots, wherein the spikes are bent downwardly to form at least one spike edge, and are formed with a plurality of fastening holes.
