Patent ID: 8529179

Claim:
A vehicular traction apparatus in combination with a vehicle for stabilizing the vehicle relative to a level surface, comprising: a traction hook defining a one-piece construction including a shank portion and an eyelet portion oppositely disposed and coaxial relative to one another therethroughout, the shank portion having a male thread portion and the eyelet portion defining an opening for receiving a first end of a traction member a second end of which is adapted to be connected to said level surface, said level surface being perpendicular relative to vertical thereat; and a connecting member mounted to the vehicle and defining a longitudinal axis, the connecting member and the longitudinal axis being horizontally disposed with respect to vertical so as to be parallel to said level surface when mounted to said vehicle, the connecting member having a hollow cylindrical shape defining a female thread portion being fully threadedly engaged by the male thread portion of the shank portion of the traction hook so as to provide no clearance therebetween and so that said traction hook is free from rotation with respect to said connecting member, a starting and an ending location of the male thread portion on the shank portion being predetermined so that upon full threaded engagement thereof with the connecting member the eyelet portion of the traction hook is disposed within a predetermined angular range in which a plane of the eyelet portion is set at an angle with respect to vertical, said predetermined angular range being 100°-150 °, wherein, when the vehicle is parked on the level surface, the traction hook is mounted to the vehicle within the predetermined angular range, and the first end of the traction member is received into the eyelet portion and the second end of the traction member is operatively connected to the level surface and positioned below the traction hook, whereupon anchoring of the vehicle to the level surface, vibrations and a bending moment generated by the traction member are directed in a clockwise direction with respect to vertical so as to be directed along the engagement direction of the male thread portion of the shank portion with the female thread portion of the connecting member so as to prevent loosening therebetween.
