Foot-propelled wheeled hobby and/or sport device

摘要

The invention is a foot-propelled wheeled hobby and/or sport device which has a central wheel (1), a frame (4) including side plates (20) connected to each other and located on both sides of the central wheel (1) at a distance from it and foot plates (5) on the lower part of the side plates (20) protruding outwards from them, located below the wheel axle (6) which has a wheel hub (2) and, furthermore, a satellite wheel (7), connected to the frame (4), with a diameter smaller than the central wheel (1). The essence of the invention is that from the point of view of the main propelling direction of the device the satellite wheel (7) is located in front of the central wheel (1). The frame (4) has front and rear frame members (21a, 21b) stiffening the side plates (20), running along their side edges opposite each other. Stable stiffening members are connected at the end parts of the foot plates (5) to the lower ends of the frame members (21a, 21b). The height above the ground of the running surface of the satellite wheel (7) is selected with consideration to the flexibility of the flexibly deformable tyre of the central wheel (1) so that when the wheel tyre (23) is depressed on the effect of the weight of an averagely built person using the device the satellite wheel (7) comes into contact with the ground, so ensuring that the foot plates (5) are horizontal or essentially horizontal.

1. A foot-propelled wheeled hobby and/ or sport device which has a central wheel (1) having a flexibly deformable tyre (23) and wheel axle (6), a frame (4) including side plates (20) connected to each other and located on both sides of the central wheel (1) at a distance therefrom and foot plates (5) on the lower part of the side plates (20) protruding outwards from the side plates, the foot plates (5) being located below the wheel axle (6) which has a wheel hub (2), and a satellite wheel (7) having a running surface, connected to the frame (4), with a diameter smaller than the central wheel (1), characterised by
the satellite wheel (7) being located in front of the central wheel (1) in the main propelling direction of the device; the frame (4) having a front frame member 21(a) and rear frame member (21b) stiffening the side plates (20), running along their respective side edges opposite each other; stable stiffening members connected at end parts of the foot plates (5) to lower ends of the frame members (21a, 21b); height above ground of the running surface of the satellite wheel (7) being based on the flexibility of the flexibly deformable tyre (23) of the central wheel (1) so that when the flexibly deformable tyre (23) is depressed in use the satellite wheel (7) comes into contact with ground, so ensuring that the foot plates (5) are substantially horizontal; and the satellite wheel being a load bearing wheel when the device is travelling in the forward direction in use.
