Abstract
An adjustable rear bumper mounted device for installing and removing tire chains from vehicles. The device is secured at one end to the rear bumper or similar portion of the car, and carries an elongated belt, webbing or the like wrapped and wound up on a take-up reel which is under spring bias tension. The outer end of the belt is fastened to the rear end of the tire chain, while the front end of the tire chain is fastened releasably to wheel clamps, so that as the car is moved forwardly, the tire chain is wound about the tire for being secured together at its ends when the rotation is completed. The wheel clamps may be either magnetic for holding the end of the tire chain to each side of the ferrous steel wheel, or "H" shaped to clamp onto spokes of "Mag" type wheels.
Claims7
A device for installing and removing tire chains from the wheels and tires of a vehicle, comprising
- first clamp means for engaging a rear body portion of the vehicle,
- tire chain means for engaging wrappingly around a tire of a vehicle for protecting it against skidding on roads, paths and pavements,
- second magnetic clamp means for engaging a forward end of said tire chain means and constructed and arranged for being releasably secured to a traction supporting member of said vehicle,
- elongated take-up belt means engaging at its forward end portion to said tire chain means at a rearward end portion thereof, and
- roller assembly means engaging said take-up belt means and said first clamp means for rolling up said tire chain means about and upon said traction supporting member.
