Stroller frame, particularly for transporting a child, with wheels that retract for storage

摘要

The invention relates to a three-wheel stroller frame (2). 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. The wheels move between an extended service position and a stowed storage position. In the extended service position the rotation axes (Y20-Y20, Y22D-Y22D, Y22G-Y22G) of the wheels extend perpendicularly to an antero-posterior plane (P) of the frame. In the stowed storage position the rotation axes extend in parallel to said plane. The antero-posterior distance (?) between the rear wheels and the front wheel is 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.
