ABSTRACT:
The portable wheel immobilizing device is comprised of two parallel covers which are attached together to angularly rotate in opposite directions about an axis perpendicular to both covers. A pair of parallel arms is attached to each cover. The arm pairs intersect at the aforesaid axis and each arm pair rotates with its cover around the aforesaid axis between a position in which all the arms are parallel to each other to a position in which the arm pairs are angularly disposed to be substantially perpendicular to each other but in which the arms in a pair remain parallel. The arms in a pair are movable in opposite directions between a length in which their combined span is at a minimum to allow compact storage of the device to a length in which their combined span is at a maximum to allow the arms to engage the outside periphery of the wheel to allow the arms to surround the wheel. One arm in each pair has an end shaped to fit around the outside of the wheel while the other arm in the pair has both an end shaped to engage the outside periphery of the wheel and an end designed to act as a chalk to immobilize the wheel upon insertion between the wheel and the ground. The arm pairs are coupled to a rotary member which is coaxial with their axis of rotation and which simultaneously rotates both pairs of arms between their minimum and maximum length.
