Abstract

A shopping trolley which can easily be pulled up steps has the basket supported on two sets of crossed arms (3) to raise the center of mass (1) with the bottom of the arms on a support frame with triple rows of rollers (7) sufficiently close spaced not to snag on the edges of the steps. Larger wheels (6) enable the trolley to be pulled/pushed along the level. The raised center of mass enables the user to simply pull the trolley up the slope of steps without having to lift the total weight.

Description

Bekannt ist mir keine Vorrichtung dieser Art für diesen Zweck.Known I am not a device of this kind for this purpose.

Die Erfindung betrifft eine Vorrichtung für einen Einkaufswagen, der unter Einsatz des Körpergewichtes durch Ziehen die Ware über die Stufen des Treppenhauses transportiert und nicht durch Heben. Dadurch beträgt die aufzuwendende Zugkraft, bei der üblichen Steigung der Stufen eines Treppenhauses von ca. 33°, nur ca. 53% vom zu transportierenden Gewicht. Bei einem üblichen Einkaufswagen muss mehr Kraft aufgewendet werden, als das Gewicht beträgt. Bei den sogenannten Treppensteigern ist der Kraftaufwand nur geringfügig weniger.The The invention relates to a device for a shopping cart, the using body weight by pulling the goods over transported the steps of the stairwell and not by lifting. Thereby is the tensile force to be applied, with the usual gradient of the steps a staircase of approx. 33 °, only about 53% of the weight to be transported. At a usual Shopping cart requires more force than weight is. In the so-called stair climbers the effort is only slightly less.

Zur Lösung dieser Aufgabe wird der Schwerpunkt 1 der Ladung, mittels einer schraublosen Befestigungsverbindung 2 – Patentanmeldung unter dem Aktenzeichen: 10 2005 060 115.4, – durch die Schere 3, die das Gestell 4 mit den Rollschienen 5 verbindet, so hochgestellt, dass dieser parallel zur Steigung der Stufen des Treppenhauses gezogen wird. Dadurch wird bei den üblichen Abmessungen der Stufen, welche eine Höhe von 18cm und eine Auftrittsfläche von 28cm haben, nach dem Kräfteparallelogramm, eine Zugkraft von 53% des zu ziehenden Gewichtes, plus Reibung, benötigt. Das Gestell 4 sowie die Rollschienen 5 können durch die schraublosen Befestigungsverbindungen 2 mühelos und ohne Werkzeug in Sekundenschnelle von der Schere (3) gelöst werden.To solve this task becomes the focus 1 the charge, by means of a screwless fastening connection 2 - Patent application under the file number: 10 2005 060 115.4, - by the scissors 3 that the frame 4 with the roller rails 5 connects so high that it is pulled parallel to the slope of the steps of the staircase. As a result, with the usual dimensions of the steps, which have a height of 18 cm and a tread surface of 28 cm, according to the parallelogram of forces, a traction of 53% of the weight to be pulled, plus friction, is required. The frame 4 as well as the roller rails 5 can through the screwless fastening connections 2 effortlessly and without tools within seconds of the scissors ( 3 ) are solved.

Der Einkaufswagen kann also in drei flache Teile zerlegt werden und somit ist der Transport in einem PKW oder das Abstellen auf kleinstem Raum möglich. Das Fahrwerk besteht aus einer linken und einer rechten Rollschiene 5. Jede Rollschiene 5 besteht aus drei achsversetzten Schienen mit je 25 Rädern 7, die einen Durchmesser von 15 mm und einen Achsabstand von 16,5 mm aufweisen. Durch die achsversetzte Dreierkombination haben die Räder 7 einen Achsabstand von 5,5 mm. Da die Treppenstufen nicht spitz sondern ein klein wenig abgerundet sind, lässt sich der Dreierverband der Rollschienen 5, ohne das geringste Holpern, wie ein glattes Brett über die Stufen ziehen. Auf der Strasse rollt der Einkaufswagen auf den beiden großen Räder 6, die sich vor den Rollschienen 5 mit den Rädern 7 befinden und deren Berührungspunkte auf der Strasse überein stimmen. Diese großen Räder 6 müssen so dicht vor dem ersten Rad 7 der Rollschienen 5 sitzen, dass kein Spalt entsteht, der zum Holpern führen kann. Die Abbildung zeigt den Einkaufswagen im Zustand des Ziehens, wobei sich der Schwerpunkt über der Achse der Räder 6 befindet. Beim Abstellen neigt sich der Einkaufswagen nach hinten, wobei die Räder 7 der Schienen 5 auf der Strasse aufliegen und der Schwerpunkt nach hinten verlagert ist.The shopping cart can therefore be divided into three flat parts and thus the transport in a car or parking in the smallest space possible. The chassis consists of a left and a right rail 5 , Each roller rail 5 consists of three off-axis rails with 25 wheels each 7 , which have a diameter of 15 mm and a center distance of 16.5 mm. Due to the off-axis triple combination have the wheels 7 a center distance of 5.5 mm. Since the stairs are not pointed but a little bit rounded, can the three-band of roller rails 5 , without the slightest bumping, like pulling a smooth board over the steps. On the street, the shopping cart rolls on the two big wheels 6 that are in front of the roller rails 5 with the wheels 7 and their points of contact on the street are the same. These big wheels 6 must be so close to the first wheel 7 the roller rails 5 sit, that no gap is created, which can lead to jarring. The illustration shows the cart in the state of pulling, with the center of gravity being over the axis of the wheels 6 located. When parking, the shopping trolley tilts backwards, with the wheels 7 the rails 5 lie on the road and the center of gravity is shifted to the rear.
