摘要

1. Improvements in the turning device and lock the rolling means in infant car, characterized in that between side members of the fork elements of the wheel, occupying the upper portion is associated with the necessary pin-block rivets appropriate material to which it is linked by its back jointly and severally vertical rotation bushing, obtaining friction resistant material, which fits with the necessary clearance to facilitate the lower end of the corresponding leg rotation device the pushchair, holding above and below the sleeve with washers appropriate thickness subject to paw car pins-fixing rivets, preparing at the same time in the lower flange a quadrangular notch provided on the bottom face and the perimeter edge supplementing the locking of rotation of the wheel. 2. Improvements in the turning device and lock the rolling means in infant car according to claim 1, characterized by the lower face of the block mentioned in the preceding paragraph, from near the hub to the front face, has been practiced a slit or recess longitudinal rectangular to the cavity section converge perpendicularly in posterior, respective holes made in the side walls designed to house coil springs that their inner ends prompt a couple of balls facing acting fixative device position latch, while towards the front end of said recess a hinge pin of an appendix, also longitudinal located in an upper portion of salvabarros wheel forming an integral part thereof, so fixed that the alternative tilting of salvabarros is achieved towards either extre mos pressing in either direction. 3. Improvements in the turning device and lock the rolling means in infant car according to claims 1 and 2, characterized in that at the rear end of the longitudinal side of the appendix are provided respective pairs of shaped grooves spherical cap constituting the points locatable through grooves suitable balls driven commented coil springs, determining the positions of approach and fit into the notch provided in the lower flange of the rotating device other minor appendix salvabarros located below the main, by which the total device lock, maneuver is performed by pressing lightly on the front end of salvabarros cited, while unlocking takes place with another slight pressure on an appropriate step is achieved provided at the end later. 4. Improvements in the turning device and lock the rolling means in infant car.
