Abstract
A tricycle has a forward oriented fork member (20) supported for rotation about a steering axis (14) of the tricycle, a handle bar (50) mounted to the fork member, a cargo unit (24) supported by the fork member, and a pair of transversally spaced linkages (30), wherein each linkage at a proximal end is linked to the fork member and at a distal end supports a respective front wheel (16) of the tricycle. The cargo unit and the linkages are shiftable between respective forward and backward end positions to thereby transform the tricycle to a wheel cart and vice versa.
Claims2
A tricycle convertible to a wheel cart comprising:
- a forward oriented fork member (20) supported for rotation about a steering axis (14) of the tricycle;
- a handle bar (50) mounted to the fork member (20);
- a cargo unit (24) supported by the fork member (20);
- a pair of transversally spaced linkages (30), each linkage at a proximal end being linked to the fork member (20) and at a distal end supporting a respective front wheel (16) of the tricycle;
- wherein:
- the cargo unit (24) and the linkages (30) are shiftable between respective forward and backward end positions to thereby transform the tricycle (10) to the wheel cart (10′) and vice versa;
- each linkage comprises a parallelogram linkage, a bottom bar (34) thereof supporting a respective front wheel (16), and front and rear bars (36, 38) thereof being linked to the fork member (20);
- and
- the linkages (30) are mutually oriented in a forward diverging manner so as to change a wheel track (t) of the front wheels (16) when shifting the linkages.
