Definitions
- the invention relates to a manually movable trolley, with a chassis, with a pusher and with at least one device for carrying goods, objects and the like, wherein the chassis two rear castors and two front castors vorge ⁇ are seen and either the pivot axis of each tilted front castor in the direction of travel of the trolley and the pivot axis of each rear castor is arranged vertically or the pivot axis of each rear castor in the direction of travel of the trolley tends ge and the pivot axis of each front castor is arranged vertically an ⁇ and wherein each swivel castor to Has a horizontal axis rotatably mounted impeller.
- the pivoting process is "out of round” and is accompanied by constant load changes, which are particularly noticeable when the trolley is moved on slightly uneven terrain in all directions.
- Another proposal recommends using a device, the pivot axis of the front castors depending on the loading state of the trolley to align position variable. This is described in detail, for example, in International Patent Applications WO 02/092408 A1 and WO 03/097380 A1, and the desired effect has proved satisfactory in the field test. If you transfer this solution to conventional, designed as a stackable shopping cart Transportwa ⁇ gene, this has the consequence that the chassis must be shortened in height on its front.
- a first solution of the problem is the use of front castors, each having a suspension device, each Federangs issued is determined in response to the direction of the impeller of the respective front castor to act on the impeller.
- each suspension device is determined depending on the direction of the impeller of the respective rear steering roller for acting on the impeller.
- steering rollers equipped with suspension devices can now be produced extremely inexpensively, so that this circumstance also contributes to an insignificant increase in the price of a transporting trolley according to the invention.
- the illustrated trolley 1 is designed in the example as a known shopping trolley.
- His chassis 2 has two front and two rear castors 6, 7 respectively.
- the chassis 2 usually carries a basket - A -
- the front castors 6 each have a suspension device 11, wherein each suspension device 11 is determined in response to the running direction of the impeller 9 for acting on the impeller 9.
- This Ein ⁇ effect is achieved by the occurring suspension forces that are effective parallel to the respective direction of the impeller 9.
- these suspension forces act perpendicularly or at right angles to the longitudinal axis of the impeller 9.
- Castors of this type are described in more detail, for example, in the patent documents WO 02/092362 A1 or DE 36 12 925 A1 or US Pat. No. 4,000,912.
- front castors 6 or as rear castors 7 such castors are capable of damping or eliminating "non-round" pivoting behavior and shocks acting on the running wheels 9. This property becomes all the more noticeable the more a trolley 1 is loaded.
- the pivot axes 8 of the front steering rollers 6 vertically and for the pivot axes 8 of the rear steering rollers 7 inclined in the direction of travel of the transport carriage 1.
- the rear steering rollers 7 each have a suspension device 11, wherein each suspension device 11 in dependence on the direction of the respective impeller 9 for acting on the impeller 9 is determined, while for the front castors 6 such roles were ⁇ used that have no suspension devices 11.
- the "tilting" of the front castors 6 or rear castors 7 is basically a compromise: the more heavily a trolley 1 is loaded, the more the inclination of the castors 6 or 7 should be selected Driving behavior of a transport vehicle 1 in particular when it is necessary to maneuver a transport vehicle 1 in place
- the inclination of the castors 6 or 7 need not be so strongly embossed is that trolley 1, in particular shopping trolleys, when loaded, must not weigh more than 250 kg - heavier wagons can no longer be maneuvered by hand - results in a load range from 0 to 250 kg, which has to be mastered found to be expedient festzu the inclination range for the front castors 6 or for the rear castors 7 preferably between 1 ° and 6 ° lay.
