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, with US-A-4 699 392 including 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 carriage carries a braking means 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 includes 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 carriage from the steps and otherwise dangerous jump. Furthermore, 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.

Claims (4)

1. Kinderwagen mit einem Haltesystem bei Stufen oder Vorsprüngen, bestehend aus einem Grundrahmen (10) mit verschiedenen Stüzträderpaarungen (14), wobei jedes Rad (14) von einem Vertikalhalter (15) getragen wird -der auf Führungen läuft und dessen Höhe in einem entsprechenden Gehäuse (16) in dem Rahmen (10) einstellbar ist - und zwischen den Haltern (15) von jeder Räderpaarung ein Horizontalschlitten (18) vorhanden ist, der sich auf einer Führung (17) in den Rahmen (10) bewegt und mit den Räderhaltern mitwirkt, um diese Räder zu bremsen und auf der gleichen Ebene zu halten, wenn sie auf der gleichen Fläche stehen. Wenn eines der Räder (14) den Boden nicht berührt und aus Schwerkraft nach unten gedruckt wird, verursacht dies die Versteilung nach oben des anderen Rads der Räderpaarung und die Berührung desselben mit einem Teil des Rahmens (10), der somit die Bewegung des Wagens verhindert.
2. Kinderwagen gemäss Anspruch 1, mit der Eigenschaft, dass der Schlitten (18) an beiden Enden zwei Abschrägungen (19) mit entgegengesetzten und nach unten konvergenten Schiefen zeigt und die Halter (15) der Räderpaarungen zwei entsprechende Abschrägungen (20) haben, die mit denen des Schlittens mitwirken.
3. Kinderwagen gemäss Anspruch 2, wobei die Abschrägungen, die mit dem Schlitten und den Räderhaltern mitwirken, vozugsweise um 45° angeordnet sind.
4. Kinderwagen gemäss Anspruch 1 bis 3, wobei der Grundrahmen (10) ein Hochreibungsband (13) um die nach unten orientierten Kanten herum aufweist, das auf dem Boden liegt, wenn sich mindestens eines von den Rädern über dem Rand einer Stufe oder eines Vorsprungs befindet.
