An anti-skid device for tires, configured such that two or more anti-skid bodies having a U-shaped cross-section are fitted therein with a tire of a car and arranged in circumferential direction of the tire so as to be connected with one another,
- the anti-skid bodies each having an exterior part along an outside surface of the tire, the exterior part being such that a front-side and a rear-side thereof in the circumferential direction of the tire are attached thereto with respective connecting components, a rear-side connecting component of each anti-skid body and a front-side connecting component of a respective next anti-skid body being connected with each other in a separable manner,
- the anti-skid device wherein
- the anti-skid bodies each comprising a front-side U-shaped member and a rear-side U-shaped member, the front-side U-shaped member having a front-side extending portion configured such that an end portion of the exterior part located along the radial direction of the tire is bent and extends toward the front-side along the circumferential direction of the tire, the rear-side U-shaped member having a rear-side extending portion configured such that an end portion of the exterior part located along the radial direction of the tire is bent and extends toward the rear-side along the circumferential direction of the tire,
- the connecting components each comprising a rod-like connecting component and a tube-like connecting component, the rod-like connecting component having an attaching end to be attached to one of the front-side of the front-side extending portion and the rear-side of the rear-side extending portion of each anti-skid body, the tube-like connecting component having an attaching end to be attached to other of the front-side of the front-side extending portion and the rear-side of the rear-side extending portion of each anti-skid body, the rod-like connecting component being allowed to be inserted into a center hole of the tube-like connecting component from an end opening thereof,
- the tube-like connecting component being attached thereto with a manipulation member, the manipulation member being configured such that an attaching rod and a connecting rod arranged in parallel with each other are connected by a manipulation rod, thus having a hook shape,
- an attaching hole and a connecting hole being formed in the tube-like connecting component to pass therethrough in a crossing direction, the attaching hole and the connecting hole being respectively located at an attaching end side and a free end side of the tube-like connecting component,
- the manipulation member being movable in the crossing direction of the tube-like connecting component by inserting the attaching rod into the attaching hole of the tube-like connecting component and inserting the connecting rod into the connecting hole of the tube-like connecting component, the manipulation member being further configured such that, when the manipulation rod is caused to move forward away from the tube-like connecting component, the connecting rod is pulled out from the connecting hole of the tube-like connecting component while the attaching rod remains inserted in the attaching hole of the tube-like connecting component, and when the manipulation rod is caused to move backward to come close the tube-like connecting component, the connecting rod is inserted into the connecting hole of the tube-like connecting component to cross the center hole of the tube-like connecting component, an elastic member being provided for applying a backward movement force to the manipulation member,
- a connecting hole being formed in the rod-like connecting component to pass therethrough in a crossing direction,
- the anti-skid device being configured such that, when the rod-like connecting component and the tube-like connecting component are connected with each other, the manipulation member is caused to move forward against the elastic member, the connecting rod is evacuated from the center hole of the tube-like connecting component, the rod-like connecting component is fitted into the center hole of the tube-like connecting component, the manipulation member is caused to move backward by an elastic force of the elastic member, and the connecting rod is inserted into the connecting hole of the rod-like connecting component, and
- the anti-skid device being further configured such that, when the rod-like connecting component and the tube-like connecting component are separated from each other, the manipulation member is caused to move forward against the elastic member, the connecting rod is pulled out from the connecting hole of the rod-like connecting component, and the rod-like connecting component is pulled out from the tube-like connecting component.
