PURPOSE:To improve the attaching characteristics by placing a mounting and removing mechanism in the middle portion between internal and external support rings of a slip tool designated as a tyre chain, connecting mounting and removing mechanisms with each other at the side of the internal support ring and attaching the tyre chain to the tyre with this connection parts placed on the ground face at the back of the tyre. CONSTITUTION:In a chain tyre slip tool which is commonly used a mounting and removing mechanism consisting of hook tools 8 and 10 and receival tools 9 and 11 is set in the middle portion between internal and external support rings 2 and 3. Each of the internal and external support rings 2 and 3 can be divided into two parts of which each is individually mounted or removed. For the mounting of this slip tool, the mounting and removing mechanisms (8 and 9) of the internal support ring 2 are connected to each other and with the connection portion placed on the ground surface at the back of the tyre, said slip tool is evolved to the left and the right and the mounting and removing mechanisms (6 and 7) are connected to each other on the side of the front face of the tyre. The hook tool 4 and the receival tool 5 of the internal support ring 2 are held by the left hand, lifted up from the left and the right side of the tyre to the top tread face of the tyre, connected to each other and put in to the back of the tyre. Then the work is finished. |
