Abstract
A dolly having large surface bearing area wheels has a frame upon which a wheeled device with wheels having insufficient surface bearing area for the terrain desired to be traversed can be supported. The dolly has a handle for propelling it. The structure may be built with provision for folding it to a more compact form.
Claims6
An all terrain dolly for supporting a vehicle with front wheels and rear wheels having insufficient surface bearing for a terrain to be traversed comprising:
- a front axle and a rear axle;
- at least one large surface bearing area wheel rotatably mounted on said front axle;
- a pair of large surface bearing area wheels rotatably mounted on said rear axle;
- longitudinally extending frame members having connections to said front and rear axles;
- said longitudinally extending frame members including longitudinal length adjustment means for changing the distance between said front and rear axles;
- a first laterally extending frame member adjacent to but spaced from said rear axle and connected at each end to said longitudinally extending frame members, whereby said first laterally extending frame member and said rear axle provide a means for supporting the rear wheels of the supported vehicle, wherein the rear wheels fit between and contact said laterally extending frame member and said rear axle;
- a pair of longitudinally spaced laterally extending frame members disposed adjacent to but spaced from said front axle and connected at each end to said longitudinally extending frame members, whereby said pair of longitudinally spaced laterally extending from members provide a means for supporting the front wheels of the supported veicle, wherein the front wheels fit between and contact said pair of longitudinally spaced laterally extending frame members;
- a laterally extending handle connected to said longitudinally extending frame members by a pair of handle supports.
