<p>The perambulator wheels are, at each side of the perambulator, in pairs (5, 6), mounted to the undercarriage by means of a pivoting element (7) which is pivotable around one longitudinal axle fixed to the undercarriage. The wheels can be pivoted into the undercarriage, which, with the wheels pivoted in, can be placed into the carriage body (8), whereby the perambulator requires little space when it is out of use. </p> |
