A car tumbler comprises a set of quarter circle-formed rockers (1) for placing under the car to be rolled over on its side, a hub flange (5) on each rocker for engagement with a wheel hub in one side of the car, the car tumbler being manipulated by a single person from only that one side of the car and requiring only dismounting the wheels on that one side, and a wheel carriage (4) on one end of each rocker which is devised in such a way that when the rocker is passed under the car the wheel carriage will engage with the inward side of and surround part of the lowermost periphery of the wheel on the other side of the car. A safety device to prevent the car rolling backward during tumbling and return to its horizontal position without any risk comprises a rotatable ratchet wheel (20) to which sustain leg (21) is welded and a main support foot (22) is connected which is parallel to the rolling axis and which in the starting position of the tumbler is in engagement with the base, a pawl (23,23′) having a pawl spring (24) and a manipulation bar (25) which extends to the end of the rocker (1) and is freely accessible, and an auxiliary support foot (22) which extends in the opposite direction thereto and which is also in engagement with the base in the starting position of the tumbler. The safety device provides a considerable rigidity and stability in the longitudinal direction of the tumbler during the mounting and dismounting thereof.

In a car tumbler including a set of substantially quarter-circle rockers for placing on a base under the car setting on the base and being engageable with the wheels or wheel hubs thereof to enable in the mounted position rolling the car over on its side on the rockers, and a hub flange connector near the center of each rocker engageable with a wheel hub on one side of the car, the improvement comprising: a wheel carriage mounted on each rocker adjacent the end thereof inserted under the car having a shape to engage the inward side and surround part of the lowermost periphery of the wheel on the other side of the car; a rotatable ratchet wheel rotatably mounted on one of said rockers in the central part thereof; a sustain leg rigidly connected to said ratchet wheel; a main support foot rotatably mounted on said one of said rockers and extending parallel to the rolling axis of the tumbler, and which is in engagement with the base in the starting position of the tumbler; a pawl pivotally mounted on said one rocker operatively engageable with said ratchet wheel for locking said ratchet wheel against rotation relative to said one rocker when engaged with said ratchet wheel; a pawl spring operatively mounted on said one rocker and engaging said pawl for resiliently urging said pawl into the engaged position with said ratchet wheel; a pawl manipulating bar movably mounted on said one rocker in engagement adjacent one end thereof with said pawl for operating said pawl and extending to the end of said one rocker adjacent said wheel carriage in freely accessible position for movement to release said pawl from engagement with said ratchet wheel; and an auxiliary support foot mounted on said one rocker and extending parallel and in the opposite direction relative to said main support foot and engaging said base in the starting position of said tumbler.
