Abstract
A ramp for a motor vehicle comprising means defining a ramp surface up which the motor vehicle wheel runs to a well into which the wheel drops and when therein is restrained from moving sideways, the ramp being collapsible to flattened condition for storage and transportation. The ramp is in three sections or frames, an upper frame, lower members to which the upper frame is pivotally connected, and a strut frame which acts as an inclined a strut keeping the upper frame at the correct angle. The frames and members can be disengaged to enable the ramp to be collapsed.
Claims3
A vehicle wheel stand comprising:
- (a) a flat upper frame;
- and
- (b) means defining a flat strut frame and the upper frame and said means defining the strut frame being positionable between;
- (i) a transport position in which the strut frame and upper frame inter fit and form a substantially flat assembly which takes up a minimum of space and
- (ii) a second position in which, when said stand rests on the ground, the upper frame inclines upwardly from the front end on the ground to an upper rear end supported by the strut frame which extends between the rear end of the upper frame and the ground and meets the upper frame at an acute angle;
- and
- the improvement comprising that the upper frame comprises a pair of spread side rails between which extend cross bar means so that a vehicle can run up the upper frame, and at the rear end the spacing between two of said cross bar means is sized to define a well into which the vehicle wheel can drop so that the rails overlap the wheel sides as to stably hold the vehicle wheel in supported condition on flat ground, and the said two cross bar means of the upper frame are disposed on opposite sides of the location where the strut frame engages the upper frame in the second position and there is a strut cross bar which is part of the strut frame, but is located under the plane of the upper frame, and in position to lend additional support to the vehicle wheel.
