ABSTRACT:
A collapsible wheel chock apparatus having a main body member with a preferably concave wheel engaging surface and a swing arm member pivotally secured to the main body member which includes a locking slot located therein with preferably a locking tab extending into the slot. A cross bar member is pivotally secured to the main body member and is movably secured and retained within the slot defined in the swing arm member. The cross bar member is adapted to be locked adjacent one end of the locking slot by a spring bias locking mechanism to facilitate holding of the wheel chock in the raised position for abutment against a vehicle wheel. The cross bar member is movable to the opposite end of the locking slot to allow the swing arm member and cross bar member both to be collapsed against the main body member for storage in this collapsed position. Engagement between the cross bar member and the swing arm member can be enhanced by the inclusion of a tab extending into the slot defined in the swing arm member and this tab or block is adapted to engage a complementary shaped slot defined in the cross bar member.
