Carts, trolleys, luggage or like load-carrying apparatus, are disclosed which incorporate two wheels which rotate about separate axes of rotation which are coplanar fixed relative to one another, and inclined to one another, preferably at an angle between 50° and 100°. They are mounted in such a way that when the apparatus rests with its wheels on horizontal ground, the plane containing the axes of rotation of the wheels may be moved to be vertical to allow the wheels to turn easily as the apparatus is moved along the ground, and moved away from vertical to cause the apparatus to be braked (as the wheels then try to travel in different directions). The assembly of wheels may be able to swivel over a narrow angular range relative to a base structure or frame. This principle may also be applied to three and four-wheeled load-carrying apparatus.
A load-carrying apparatus comprising a base structure and two spaced-apart rotatable ground-engaging members freely rotatably mounted on axles fixed relative to the base structure, with the axes of rotation of each of the two ground-engaging members about the axles being fixed relative to one another and being coplanar and extending at an angle to one another of at least about 10°, and including means to adjust the angle between the plane of a substantially horizontal surface on which the apparatus rests and the plane in which each said axis of rotation of the ground-engaging members extends to be 90°.
Apparatus for transporting loads including a pair of freely rotatable spaced apart ground-engaging wheels to enable the apparatus to be pulled or pushed along with the wheels in contact with the ground, a load-carrying frame or container supported on the wheels, wherein the wheels have a high positive camber angle and are each mounted for free rotation on a stub axle, a connector piece extends laterally from each stub axle and each connector piece is mounted at its end remote from the stub axle, to enable the connector piece to swivel, relative to the frame or container, about an axis which is horizontal when the apparatus is being used, over an angular range of 5 to 25°, and means enabling the frame or container to be rotated about a horizontal axis relative to the ground on which the apparatus rests to a position in which the plane containing the axes of the stub axles is vertical.
Load-carrying apparatus comprising an elongate shaft, a handle mounted on a first end of the shaft, three stub axles mounted on a second end of the shaft, and three rotatable ground-engaging members, each of said ground-engaging members being mounted on one of the three stub axles, wherein the stub axles are mounted evenly around the shaft and an axis of rotation of each of said rotatable ground-engaging members intersects a longitudinal direction of the shaft at an angle of from about 25° to about 80°.
A load-carrying cart comprising a flat bed for supporting a load, at least three ground-engaging wheels mounted below the flat bed, a handle for pulling the cart along, and means to enable the handle to swivel about a substantially horizontal axis, wherein two wheels of the at least three ground-engaging wheels are mounted spaced apart and said two wheels are mounted on axles rigidly fixed to the handle, and with said two wheels being set at an angle to one another whereby axes of rotation of the two wheels are coplanar and the angle between a plane containing the axes of rotation and a surface of the flat bed are variable by swivelling the handle.
