<p>The invention relates to an auxiliary device that facilitates the movement of standard pushchairs over sandy or similar surfaces. The inventive device comprises rolling elements consisting of hollow bodies (11 and 11') having a cone frustum-type configuration with few degrees of opening. Said rolling elements can be removably fixed in a coaxial manner to the internal or external area of the wheels of the wheel trains (2 and 2') of the standard pushchair either directly or using a coupling. In this way, the surface of the rolling element which is in contact with the sand is increased considerably. Moreover, the aforementioned hollow part (11) is provided with another part (15) which is used to connect parts 11 and 11'. Furthermore, the invention comprises a front traction handle (6) which can be removed and folded or a removable rear handle (31). Once installed, the elements of the invention are designed so as not to interfere with the normal operation or folding of the pushchair.</p> |
