Abstract:
The invention provides a motorised driving wheel (1) comprising a circumferential rim (2) defining an axis of revolution and a motor (3) for producing a driving force. The motor comprises an output shaft rotatable around a motor axis, the motor axis and the axis of revolution being non-parallel. Furthermore, the driving wheel comprises a transmission system for transmitting the driving force from the motor to the circumferential rim. The transmission system is arranged to transform rotation of the output shaft around the motor axis into rotation of the circumferential rim around the axis of revolution. The transmission system may drive an annular element (5) forming the rim, or it may drive a central driving axle (114).
Abstract:
A collapsible golf trolley comprises a frame (176, 276) defined by at least two, preferably four, frame members (171, 172, 173, 174, 203), and a wheel structure (122, 222). The frame members are pivotally interconnected at hinges (106;177, 205), whereby in a first configuration, the frame members define a casing (100, 200) for the wheel structure parts, the casing having a length which is shorter than the sum of the lengths of each of the frame members. In a second configuration, the frame members coextend in a longitudinal direction to define the frame (176, 276). There is further provided a collapsible wheel structure having arms (150, 152, 258, 252) defining pivotally interconnected arm sections (154, 156, 158, 160;254, 256, 258, 260) which, in a first, folded configuration define a partial cylindrical shape, and which in a second, unfolded configuration form an S-shape.
