Abstract
A wheeled vehicle includes a front driven shaft mounted to and rotatable relative to a front frame portion, a front wheel body mounted to rotate with the front driven shaft, a rear driving shaft mounted to and rotatable relative to a rear frame portion and having an upper driving end to be operated manually, and a force transmitting mechanism including front and rear rotary members which are respectively coupled to the front driven and rear driving shafts, and a transmitting member connected to the front and rear rotary members so as to transmit rotational movement of the rear rotary member, which is initiated manually by the rear driving shaft, to drive the front rotary member and the front driven shaft to rotate, thereby resulting in a swiveling movement of the front wheel body.
Claims11
A wheeled vehicle comprising:
- a mounting frame including front and rear frame portions opposite to each other in a longitudinal direction;
- a front driven shaft mounted to and rotatable relative to said front frame portion about a front swivel axis in an upright direction transverse to the longitudinal direction, and having a lower driven end and an upper driven end which extends upwardly from said lower driven end along the front swivel axis;
- a front wheel body mounted to be rotated with said lower driven end about the rear swivel axis, and adapted to be rollable on the ground;
- a rear driving shaft mounted to and rotatable relative to said rear frame portion about a rear swivel axis in the upright direction, and having a lower driving end and an upper driving end which extends upwardly from said lower driving end to be operated manually;
- and
- a force transmitting mechanism having front and rear rotary members which are coupled to and which are rotated with said front driven and rear driving shafts about the front and rear swivel axes, respectively, and a transmitting member disposed to couple said front rotary member with said rear rotary member such that rotational movement of said rear rotary member about the rear swivel axis, which is initiated manually through said upper driving end of said rear driving shaft, is transmitted to drive said front rotary member and said front driven shaft to rotate about the front swivel axis, thereby resulting in a swiveling movement of said front wheel body.
