Description
Die Erfindung bezieht sich auf eine Vorrichtung an Kinderwagen zum stoßfreien Fahren auf Treppen, bestehend aus einem an beiden Seiten zwischen den Rädern des Wagens schwenkbar angeordneten, auf der Gleitfläche mit einem endlosen Band versehenen Rahmen.The invention relates to a device on strollers for shock-free Driving on stairs consisting of one on either side between the wheels of the Carriage pivotably arranged, provided on the sliding surface with an endless belt Frame.
Die bekannten, mit und ohne endloses Band ausgerüsteten Vorrichtungen, um Kinto derwagen über Treppen zu fahren, haben den Nachteil, daß beim Einschalten und Gebrauch der Vorrichtung das ganze Fahrgestell des Wagens ausgeschaltet werden muß, wodurch einerseits die Baulänge der Vorrichtung eine sehr große wird und anderseits die Kippgefahr erhöht wird.The well-known devices, equipped with and without an endless belt, to Kinto To drive derwagen over stairs have the disadvantage that when switched on and in use of the device, the entire chassis of the car must be switched off, whereby on the one hand the overall length of the device is very large and on the other hand the risk of tipping over is increased.
Das Neue der Erfindung besteht darin, daß der unter Wirkung einer Druckfeder stehende, auf einem Tragzäpfen axial verschiebbare Rahmen einen Schlitz aufweist, in den zur Verriegelung des Rahmens in dessen beiden Endstellungen ein dem Schlitz angepaßter Ansatz des Tragzapfens greift. Der Abstand der Rahmen in der Gebrauchsstellung ist gleich dem Radabstand, und die Unterseite der endlosen Bänder liegt in der die tiefsten Punkte der hintereinänderlaufenden Räder verbindenden Geraden.The novelty of the invention is that the under the action of a compression spring standing frame axially displaceable on a support spigot has a slot, in the one to lock the frame in its two end positions in the slot adapted approach of the trunnion engages. The distance between the frames in the position of use is equal to the wheel spacing, and the underside of the endless belts lies in the lowest point of the one behind the other Straight lines connecting the wheels.
In der Zeichnung ist der Erfmdungsgegenstand beispielsweise dargestellt, und zwar zeigen:The subject matter of the invention is shown in the drawing, for example demonstrate:

Abb. 3, 4 und 5 die beispielsweise Ausbildung des Rahmens und die Anordnung des Tragzapfens.Fig. 3, 4 and 5 the example of the design of the frame and the arrangement of the Trunnion.
An den Tragfedern b eines Kinderwagens a ist links und rechts, jeweils zwischen den hintereinanderlaufenden Rädern /, auf einem Tragzapfen 0 ein dem Umfang der Räder I angepaßter, um i8o° drehbarer Rahmen e vorgesehen, um dessen Teil / ein über zwei oder mehr vorgesehene Rollen e und ex laufendes Gummiseil oder endloses Band d geführt ist. Die Rollen e und ex sind auf den Achsen k und ^1 in an dem Rahmen c vorgesehenen Lappen m und η gelagert. Der Rahmen c wird in den beiden Endstellungen von dem rechteckig ausgebildeten Ansatz g des Zapfens 0, auf welchen der Rahmen c vermittels des rechteckigen Schlitzes i geschoben wird, durch die Druckfeder h gehalten. Unter Zusammendrückung der Feder h wird der Rahmen c von dem Ansatz g abgezogen und um den Zapfen 0 vor den Lauf rädern links und rechts um i8o° gedreht, worauf die wieder freigegebene Feder h den Rahmen c in der jeweiligen Stellung mittels des Schlitzes i und des rechteckigen Ansatzes g festhält.On the suspension springs b of a stroller a, a frame e adapted to the circumference of the wheels I and rotatable by 180 ° is provided on the left and right, in each case between the wheels running one behind the other /, on a support pin 0 , around its part / one provided over two or more rollers e and e x running rubber rope or endless belt d is guided. The rollers e and e x are mounted on the axes k and ^ 1 in lugs m and η provided on the frame c . The frame c is held in the two end positions by the rectangular extension g of the pin 0, onto which the frame c is pushed by means of the rectangular slot i , by the compression spring h . Under compression of the spring h , the frame c is pulled off the approach g and rotated around the pin 0 in front of the running wheels left and right by i8o °, whereupon the released spring h the frame c in the respective position by means of the slot i and des rectangular approach g holds.
