Definitions

  • the present invention relates to a pushchair for children.
  • the term "pushchair” is used to indicate any hand-pushed vehicle comprising a wheeled chassis on which a seat, cot or bassinet or the like, is fitted, including baby carriages.
  • Pushchairs for children which comprise a chassis provided with three or four wheels for resting on the ground and on which a seat is fitted.
  • Another drawback of known pushchairs consists in that they do not allow to control and modify the orientation of the freely pivoting wheels in the selected direction.
  • the aim of the present invention is to provide an improved pushchair for children which has an agile structure which can be maneuvered easily.
  • An object of the present invention is to provide an improved pushchair for children which is stable and safe regardless of the conditions of the ground on which it rests.
  • Another object of the present invention is to provide an improved pushchair for children which is versatile and can be adapted easily to several uses and to the different stages of the growth of a child.
  • Still another object of the present invention is to provide an improved seat for children which can be opened and closed with a limited number of operations which are simple to perform.

  • a slot 33 is provided within which corresponding abutment portions of the rear bar 26 and of the rear tab 29 slide when the pushchair 1 is in the open configuration for use and steering maneuvers are performed.
  • the hook 30 is disengaged; in this manner, the upper coupling 15 and the lower coupling 16 can rotate about the respective pivot 21 and 22 with respect to the sleeve 14, so as to close the maneuvering handlebar 7 and the axles 13 by folding flat.
  • the gear system 23a-23b links the rotation of the lower coupling 16 to the rotation of the upper coupling 15, thus allowing the simultaneous flat-folding closure of the maneuvering handlebar 7 and of the rear wheels 4.
  • the axles 13 are associated with the lower coupling 16 by means of an umbrella-style mechanism which indeed allows its "umbrella-style" opening and closure.
  • Such mechanism comprises, for each of the two rear wheels 4, a slot link 34, which is defined in the elongated body 27 of the lower coupling 16 and lies substantially parallel to the axis 1 Ia.
  • a rod 35 has an end which is articulated to a slider which can slide along the slot link 34 and the opposite end which is articulated to the respective axle 13 proximate to the end of the latter which is associated with the corresponding rear wheel 4.
  • the end of the axle 13 that lies opposite the end for the coupling of the corresponding rear wheel 4 is articulated to one of the two wings 28 so that it can rotate about an axis 28a which is parallel to the articulation axes of the two opposite ends of the rod 35.
  • a retainer 36 of the removable type and constituted for example by a spring-loaded pin which is inserted slidingly within a corresponding slot 37, locks temporarily the sliding of the slider of each of the two rods 35 along the slot link 34.
  • the slider associated with the end of the two rods 35 is at the lower stroke limit of the slot link 34 and is kept locked in this position by the retainer 36.
  • the retainer 36 By acting on the retainer 36 it is possible to release the sliding of the slider associated with the end of the two rods 35 and make it slide toward the upper stroke limit of the slot link 34.
  • the rods 35 move the axles 13 closer to the elongated body 27, thus closing them umbrella-style.
  • Each rod 35 is further provided with a shock absorber 35a.
  • the maneuvering handlebar 7 comprises a lever 38, which has one end fixed to the upper end of the shaft 1 1 and in particular to the tubular union 25 and the opposite end articulated to a handle 39.
  • the lever 38 is constituted by a tubular element which is closed in a loop and is rigidly coupled, by means of screws, to the tubular union 25.
  • the tubular element of the lever 38 acts as a coupling for containers or bags.
  • the handle 39 is also constituted by a tubular element which is closed in a loop.
