Description

  The present invention relates to an anti-slip device mounted on a tire of an automobile.

  The anti-slip device exemplified in the patent literature is fitted with an anti-slip body having a U-shaped cross section from the outer periphery side of an automobile tire. Several anti-slip bodies are arranged at almost equal intervals on the entire circumference of the tire, and the adjacent ones are connected. Several anti-slip bodies are fitted into the outer periphery of the tire in a ring and attached to the tire. When the anti-slip device is removed from the tire, the anti-slip bodies are separated from each other and the anti-slip body is removed from the tire.

  The anti-slip body having a U-shaped cross section includes a front U-shaped member and a rear U-shaped member in the tire rotation direction when the vehicle is moving forward, and an inner linear member along the inner surface of the tire. The U-shaped members on the front side and the rear side are bars that are curved in a U shape, and have a transverse part that crosses the ground contact surface of the tire, an outer part that extends along the outer surface of the tire, and an inner part that extends along the inner surface of the tire. The inner linear members are chained to connect the inner portions of the front U-shaped member and the rear U-shaped member.

  The outer part of the anti-slip body has connecting members attached to the front end and the rear end in the circumferential direction of the tire. The connecting member is chained and attached with a connecting tool. When connecting the anti-slip bodies arranged in the circumferential direction of the tire, the connecting member on the rear side of the anti-slip body is connected to the connecting member on the front side of the rear non-slip body in a separable manner.

  In order to stably support the anti-slip body at a predetermined position of the tire, a non-slip body is provided with a contact member that contacts the outer surface of the tire and a contact member that contacts the inner surface of the tire. The outer contact member and the inner contact member are applied to the inner peripheral side rather than the outer peripheral side of the outer side surface and inner side surface of the tire. The tire has a cross-sectional shape that is flattened by the ground contact and is restored after the ground contact, and the outer diameter and the width periodically change. The amount of fluctuation is smaller on the inner peripheral side than on the outer peripheral side.

  The outer contact member and the inner contact member are provided at the front and rear portions of the anti-slip body, respectively. Specifically, the outer contact member is provided on a connecting plate interposed between the outer portion of the front U-shaped member and the front connecting member, and the outer portion of the rear U-shaped member is connected to the rear side. It is provided on a connecting plate interposed between the members. The inner abutting member is provided on the connecting plate interposed between the inner side of the front U-shaped member and the inner linear member, and between the inner side of the rear U-shaped member and the inner linear member. It is provided on the intervening connecting plate. In the front part and the rear part of the non-slip body, the outer and inner contact members are respectively arranged at an oblique front position rather than a straight front position facing the width direction of the anti-slip body. The distance between is long. The non-slip body is easy to attach to and detach from the tire.
