| 摘要 |
The invention relates to a so-called three-wheel stroller frame (2) in which the front wheel (20) and the two rear wheels (22D, 22G) are respectively and simultaneously movable relative to a front arm (12) and to two rear arms (14D, 14G) rigidly connected to each other, between an extended service position, in which the rotation axes (Y20-Y20, Y22D-Y22D, Y22G-Y22G) of the wheels extend perpendicularly to a same antero-posterior plane (P) of the frame, and a stowed storage position in which said rotation axes extend in parallel to said plane, the antero-posterior distance (&Dgr;) between the rear wheels and the front wheel being then smaller than when the wheels are in the expanded position. In order to move the wheels in a quick, simple and easy manner, the stroller frame also includes a specific handle (60) for manually driving a wheel movement means arranged at the front end of the front arm.
