Title: A NON-SKID DEVICE FOR VEHICLE WHEELS
Abstract:
A non-skid device for automobile wheels features a holder (3) separately mountable on the wheel disc (2) and a non-skid mechanism (4) which is attachable to the holder (3). The non- skid mechanism (4) features adjustable arms (5) provided with the engagement surfaces (8) at the ends. These engagement surfaces abut to the circumferential surface of the tire (1) in the working position. The non-skid mechanism (4) features a bottom plate (16) mountable to the holder (3) and to the top plate (17) attached to the bottom plate (17). The arms (5) with the engagement surfaces (8) are arranged with radial sliding and pivoting fit around their longitudinal axis on the outer side of the bottom plate (17). The arms (5) which are formed by two parts (6 and 7), of which the upper part (7) is pivotable relative to the lower part (6), are arranged in the guides (9), into which the longitudinal groove (10), followed by the helical part (11), the guiding element (12) connected with the upper part (7) of the arm (5) extends. The lower part (6) of the arm (5) is cushioned and connected to the gear mechanism. The engagement surfaces (8) are sliding with their bearing portion in the upper part (7) of the arm (5) and pushed by the spring (13) in the direction from the upper part (7) against a stop.
