Definitions

  • the invention relates to children's carts and more particularly to a children's carriage provided with a stop system which does not prevent movement as soon as it encounters a step or a jump.
  • the trolley is already known, including in patent US 4,699,392 comprising a braking system capable of reacting to the presence of a step or a jump to prevent the trolley from moving beyond the safety margin.
  • the base of this cart carries a craus on the ground and has three pairs of wheels.
  • the wheels of each pair are mounted on a support tilting on a horizontal axis so that, if a wheel goes beyond the edge of a step it lowers and causes the lifting of the wheel on the opposite side.
  • the support on at least two wheels is lacking and part of the base rests on the ground preventing the advance of the carriage to save the child.
  • the cart in question comprises a cornice base (10) on which is fixed a frame (11) carrying a plate (12) with the housing for the child who will use the cart.
  • a profile (13) of rubber, plastic or the like directed downwards and intended to rest on the ground.
  • the base (10) is also provided with support wheels (14) arranged in pairs and conveniently placed and separated to ensure correct and balanced support for the carriage in the upright position.
  • each wheel being provided with a support (15) guided and movable in height in a housing (16) provided in the base (10).
  • the support (15) and the housing (16) are arranged so as to allow the sliding guide of the support (15) in the vertical direction.
  • the two ends of the slide (18) have chamfers (19) with opposite inclination which converge downwards, preferably at 45 °, and interact with two corresponding chamfers (20) provided on the vertical supports (15) of the wheels (14) .
  • the base (10) therefore lowers until it rests on the ground - v. Fig. 4 - and brake the further advancement of the carriage, also helped by the braking profile (13) along the perimeter of the base. This avoids the risk of a possible fall of the trolley from the steps and otherwise dangerous jumps.
  • the condition of use of the trolley is automatically reactivated as soon as the trolley is placed again with all its wheels on the same plane.
