Collapsible tricycle for children - has frame with rigidly coupled rear fork and rotatable front fork

摘要

The collapsible child's tricycle has a frame (2) which the rear fork (3) and the steerable front wheel assembly (5) are attached. The front fork (6) can be swivelled out of the steerable assembly so that it occupies the space bounded by the rear wheels. The assembly (5) consists of a box-like structure having a pair of aligned openings on its rear side which engage with a link pin (11). The lower surface of the structure has a transverse part (13) which connects the two uprights (6) of the front fork. Such a design avoids the use of a special frame joint specifically intended to aid folding.
