Abstract

A mounted rack hoist (1, 2, 3) enables the pram or trolley to climb steps and stairs and consists of a small diameter (20 mm) wheel (1) mounted on a cranked lever (2A, 2B). This wheel is joined via gear to a rack (3A, 3B) at step height thus moving up and down so the lever lifts the front wheels over the step. At the start of the lift, the rack is driven forward by a relaxing gas spring (4) so as to force the lever and wheel (1) down and so raise the pram etc. front axle over the step. The pram is then pushed forward as held level by the handle (8), onto the step after which the spring is re-tensioned by the handle-fitted Bowden cable (6) so the lever (2) and roller reset to allow the next step etc. to be negotiated. After each step, the lever is once again fixed to the handle.

Description

Normale o.g. Fahrzeuge können von nur einer Person nicht oder nur mit erheblicher Mühe Treppen und Stufen überwinden. Die im Schutzanspruch (1) angegebene Erfindung löst das Problem in der beschriebenen Weise, daß durch das Bedienen der Geräte eine Person Hindernisse, wie Treppen und Stufen, allein überwinden kann (siehe Zeichnung).Normal above Vehicles cannot be operated by just one person or climb stairs and steps with great difficulty. The invention specified in the protection claim (1) solves this Problem in the manner described that by the operation the devices a person obstacles such as stairs and steps, alone can overcome (see drawing).

Claims (1)

Zusatzgerät für Kinderwagen und Einkaufswagen, welches ein­ zelnen Personen es ermöglicht, Treppen oder Stufen mit dem Wagen ohne fremde Hilfe durch ein gekoppeltes Hub- und Rollsystem zu überwinden.
Das Zusatzgerät für Kinderwagen (Einkaufswagen) ist da­ durch gekennzeichnet, daß ein kombiniertes Zahnrad-Hub­ system, welches am Kinderwagen (Einkaufswagen) montiert wird, es ermöglicht, diesen über Treppen zu heben und zu schieben.
  • a) Ein an einem gekröpften Hebel montiertes Rad, d = 20 mm, wird über ein Zahnrad in Verbindung mit einer Zahnstange in Stufenhöhe auf und ab bewegt, und zwar in der Form, daß der gekröpfte Hebel die Vorderräder der o.g. Geräte um eine jeweilige Stufenhöhe emporhebt.
    Die Zahnstange wird bei Beginn des Hubvorganges durch eine gespannte Gasdruckfeder durch Entspannen nach vorne ange­ trieben, so daß der gekröpfte Hebel mit dem kleinen Räd­ chen (d = 20 mm) nach unten gedrückt wird und die Vorder­ achse des Kinderwagens (Einkaufswagens) um eine Stufenhöhe emporhebt. Anschließend wird der Wagen, der an der Griff­ stange waagrecht gehalten wird, um die Stufenbreite nach vorne auf die Stufe geschoben. Durch den an der Griff­ stange befestigten Bowdenzug wird die Gasdruckfeder wie­ der gespannt, so daß der gekröpfte Hebel mit dem kleinen Rädchen in die Ursprungslage zurückkehrt und der nächste Hubvorgang kann von neuem beginnen.
  • b) Nach Beendigung des Hubvorganges wird der Hubhebel an der Griffstange in Ruheposition befestigt.
Additional device for strollers and shopping trolleys, which enables a single person to climb stairs or steps with the stroller without outside help thanks to a coupled lifting and rolling system.
The additional device for strollers (shopping trolleys) is characterized in that a combined gear-lifting system, which is mounted on the stroller (shopping trolley), allows it to be lifted and pushed over stairs.
  • a) A wheel mounted on a cranked lever, d = 20 mm, is moved up and down by means of a gearwheel in conjunction with a rack at a step height, in such a way that the cranked lever moves the front wheels of the above-mentioned devices by a respective step height lifts up.
    The rack is driven at the beginning of the lifting process by a tensioned gas pressure spring by relaxing to the front, so that the cranked lever with the small wheel (d = 20 mm) is pressed down and the front axle of the stroller (shopping trolley) by a step height lifts up. Then the trolley, which is held horizontally by the handle bar, is pushed forward by the step width onto the step. Due to the Bowden cable attached to the handle, the gas pressure spring is tensioned so that the cranked lever with the small wheel returns to the original position and the next lifting process can begin again.
  • b) After completion of the lifting process, the lifting lever is attached to the handle bar in the rest position.
