Abstract

The trolley is designed to be pushed by hand and several trolleys may be pushed into each other forming a train of trolleys. It has wheels pivoted about a vertical axis, and the rear wheels may be locked in a position, for forward movement. The locking is released, when a second trolley is pushed into the first, and engage automatically, when it is removed. The locking may also be released by a grip (2). A lever (3) below the grip may be moved by hand towards it. The lever movement is transmitted via rod (5) onto the control elements (7) for the locking.

Description

"Von Hand bewegbarer TransDortwaKen" "Manually moveable TransDortwaKen"

Die Erfindung bezieht sich auf einen von Hand bewegbaren, mit gleichartigen Wagen ineinanderschiebbaren Transportwagen, dessen Räder um vertikale Achsen schwenkbar sind, wobei die Hinterräder für die übliche Transportverwendung des Wagens hinsichtlich ihrer Verschwenkbarkeit um ihre vertikalen Achsen in einer Lage arretierbar sind, in der die Drehachsen der Hinterräder rechtwinklig zur Längsachse des Wagens orientiert sind, die Schwenkarretierung der Hinterräder durch einen von hinten in den ersten Wagen eingeschobenen zweiten Wagen aufgehoben wird und beim Herausziehen des zweiten Wagens selbsttätig wieder einrastet, wenn die Hinterräder sich in ihrer Geradeausstellung befinden, nach Patent ... (Anmeldung P 28 o3 oo3.7-21).The invention relates to a manually movable, with similar Trolleys telescopic trolleys, the wheels of which can be swiveled around vertical axes are, with the rear wheels for the usual transport use of the car with regard to their pivotability about their vertical axes can be locked in one position, in which the axes of rotation of the rear wheels are oriented at right angles to the longitudinal axis of the car are, the swivel lock of the rear wheels by one from behind in the first Trolley inserted second trolley is lifted and when pulling out the second The car automatically locks in again when the rear wheels are in their straight-ahead position located, according to patent ... (application P 28 o3 oo3.7-21).

Der Erfindung liegt die Aufgabe zugrunde, den eingangs definierten Wagen derart auszubilden, daß er sich auch quer verfahren läßt.The invention is based on the object defined at the outset Train the car in such a way that it can also be moved transversely.

Diese Aufgabe wird erfindungsgenäß dadurch gelöst, daß ein Handgriff vorgesehen ist, über den die Schwenkarretierung ebenfalls aufgehoben werden kann.This object is achieved according to the invention in that a handle is provided, via which the swivel lock can also be canceled.

Will der Benutzer den Wagen quer verfahren, so betätigt er den Handgriff und löst die Arretierung.If the user wants to move the carriage transversely, he actuates the handle and releases the lock.

Weitere Einzelheiten der Erfindung ergeben sich aus der Zeichnung, in deren einziger Figur ein Ausführungabeispiel der Erfindung veranschaulicht ist.Further details of the invention emerge from the drawing, in the single figure of which an exemplary embodiment of the invention is illustrated.

In dieser Figur ist das hintere Ende eines Transportwagens veranschaulicht, wobei die Räder weggelassen worden sind.In this figure, the rear end of a transport cart is illustrated, with the wheels omitted.

Sie sitzen an dem rechten unteren Ende der Rohre 1. Mit 2 ist der Griff des Transportwagens bezeichunet.They sit at the lower right end of the tubes 1. With 2 is the Handle of the transport trolley.

Die erfindungsgemäße Vorrichtung besteht aus einem Handgriff 3, der um eine Welle 4 schwenkbar gelagert ist und mit einer nach unten laufenden Stange 5 verbunden ist, deren unteres Ende 6 ist abgewinkelt und drückt auf einen Hebel 7, der bei 8 an dem Rohr 1 angelenkt ist. Er besitzt an seinem unteren Ende eine nicht dargestellte Klinke, die in die Radgabel des Hinterrades einrastet. Wird der Hebel 3 im Gegenuhrzeigersinn gegen die Kraft einer Feder 9 verschwenkt, dann wird die Stange 5 und das linke Ende des Hebels 7 nach unten bewegt. Die nicht dargestellte Klinke des Hebels 7 rastet infolgedessen aus der Radgabel aus. Wird der Griff 3 wieder losgelassen, und befindet sich das Hinterrad des Transportwagens in seiner Geradeaus stellung, vorzugsweise in seiner Vorwärts-Geradeausstellung, dann rastet die Klinke aufgrund der Schwerkraft wieder in die Radgabel ein. Mit lo sind zwei Wangen bezeichnet, die an dem Hebel 7 befestigt sind, das Rohr 1 umgeben und zu Führungszwecken für den Hebel 7 dienen.The device according to the invention consists of a handle 3, which is pivotably mounted about a shaft 4 and with a downwardly running rod 5 is connected, the lower end 6 is angled and presses on a lever 7, which is articulated at 8 on the tube 1. It has one at its lower end pawl, not shown, which engages in the wheel fork of the rear wheel. Will the Lever 3 is pivoted counterclockwise against the force of a spring 9, then the rod 5 and the left end of the lever 7 moved downwards. The one not shown As a result, the pawl of the lever 7 disengages from the wheel fork. If the handle 3 released again, and the rear wheel of the trolley is in his Straight ahead position, preferably in its forward straight-ahead position, then locks the pawl back into the wheel fork due to gravity. With lo there are two Designated cheeks, which are attached to the lever 7, surround the tube 1 and to Serve as a guide for the lever 7.
