发明名称 Traction aid device
摘要 A traction aid for providing traction to a wheel of a vehicle relative a ground surface has two sections, composed of side members and traction members, connected by a connecting mechanism enabling pivotal unfolding and folding of sections between folded and unfolded configurations for device. In unfolded configuration, sections are longitudinally opposed end-to-end to allow wheel to pass over both sections when device is deployed on ground surface. In folded configuration, sections are folded together and extend substantially parallel one another. Each section has a plurality of gripping members attached to side members and extending therefrom. Each gripping member is configured such that, when device is deployed in unfolded configuration on ground surface, gripping member extends theretowards for grippingly protruding thereinto, gripping member otherwise, for folded configuration, extending towards an adjacent side member of another section, the adjacent side member extending therebeyond to impede gripping member from engaging foreign objects.
