Abstract
Disclosed herein is a coupling system for a tire traction device comprising: a first wedge block, a second wedge block, a first wedge receiver and a second wedge receiver. In one example, each wedge block includes a surface defining a tie receiver. Also disclosed are first and second wedge receivers. Also disclosed is a tire traction device and a method for producing the tire traction device. The tire traction device removably attached to a vehicle tire or wheel. The traction device in one example comprising: a tread portion comprising a tread surface, the tread portion comprising a first material; a plurality of sidewall portions, the sidewall portions comprising a second material; wherein the tread portion and sidewall portions are cast in a single mold as a unitary structure.
Claims14
A tire traction device removably attached to a vehicle tire while inflated, the traction device comprising:
- a. a tread portion comprising a tread surface, the tread surface being a radially outward surface of the tire traction device, the tread surface comprising a first material;
- b. an interlinked monocast structure comprised of a plurality of sidewall portions:
- c. the sidewall portions having an outermost surface;
- d. the sidewall portions comprising a second material;
- e. wherein the first material and second material are different compositions;
- f. wherein the first material does not substantially extend to the sidewall portions;
- g. wherein the tread portion and sidewall portions are a unitary structure;
- and
- h. the tire traction device comprising a first circumferential end and an opposing circumferential end removably coupled to the adjacent first circumferential end via a coupling system.
A tire traction device removably attached to a vehicle tire while inflated, the traction device comprising:
- a. a plurality of segment regions, each segment region comprising:
- (i) a tread portion comprising a tread surface, the tread portion having an opening there through which does not extend to a sidewall portion of the traction device;
- (ii) the tread portion comprising a first material;
- (iii) the opening defined by a plurality of longitudinal members of the tread portion and a plurality of transverse members of the tread portion;
- (iv) a plurality of the sidewall portions, each sidewall portion comprising a surface defining a substantially trapezoidal opening which does not extend to the tread surface;
- (v) the sidewall portion comprising a second material;
- (vi) wherein the first material and the second material are different compositions;
- (vii) each trapezoidal opening having a radially outward side formed by one of the longitudinal members of the tread portion;
- b. wherein the tread portion and sidewall portions are a unitary structure.
