Definitions
- the invention relates to a hand-movable transport trolley, with a chassis that carries front and rear swivel castors, wherein either the front or the rear swivel castors are attached to the chassis with the aid of means that react to the weight of the trolley that when a weight load occurs, the swivel axis of the castors influenced by the means assume an inclined position in the direction of sliding of the transport carriage.
- Transport trolleys of this type can be driven more straightforward under heavy weight loads, i.e. with a high load, than transport trolleys which lack the means just mentioned.
- Proposed solutions to this are not only described in international patent applications WO 94/08801 AI, WO 03/097 380 AI and PCT / GB 02/02315, there are also further suggestions in patent applications DE 36 12 925 AI, EP 0 820 881 A2 , GB 2 333 698 AI and US 4,000,912. All of the proposed solutions disclosed in these documents have a common disadvantage, which is that the proposed means, which are intended to cause a change in position of the swivel axis of the swivel castors when the weight occurs, take up a large number of parts.
- the means are formed by a resilient supporting part which has an upper and a lower leg, the upper leg connected to the lower leg via a connecting section being fastened to the chassis and the lower leg.
- right leg is designed to carry the front or rear castors.
- the proposed solution impresses with its simplicity, because parts such as compression springs, damping elements, stop pieces, joints and the like, as are used in the prior art, are not required in the trolley according to the invention.
- the flexurally elastic part rather combines at least four advantageous functions. It is a fastener for the castors. It also connects the two swivel castors in order to achieve at least approximately synchronous behavior when the swivel castors are to assume their inclined position in the sliding direction of the transport carriage when subjected to a weight load.
- the flexurally elastic properties of the support part replace the previously used compression springs and finally the generously curved connecting section can even take on the function of a bumper if the support part, arranged transversely, forms the front boundary of the chassis of the transport vehicle.
- 1 shows a hand-movable transport trolley; 2 shows a supporting part;
- Fig. 3 shows the supporting part in a slightly loaded state and Fig. 4 shows the supporting part in a heavily loaded state.
- the trolley 1 shows, for example, a trolley 1 which can be moved by hand and is designed as a shopping trolley.
- the trolley 1 has a chassis 2 which carries a device 6 for receiving and transporting objects.
- a sliding device 7 serves to move the transport carriage 1.
- Front and rear steering rollers 8, 9 are arranged on the chassis 2.
- swivel castors 8, 9 can be rotated about a vertical axis 10 (swivel axis) which is arranged at a lateral distance from the wheel axis 11, so that the swivel castors 8, 9 always assume a caster position.
- the chassis 2 has two spars in the example 3, to which a transversely extending, resilient support part 12 is fastened at the front.
- the support member 12 On the support member 12, two front castors 8 and a vertical axis 10 are rotatably arranged.
- the two rear castors 9 are attached directly to the bars 3, in the rear area.
- the support part 12 can, however, also be arranged on the rear of the spars 3 for carrying the rear steering rollers 9.
- Fig. 2 shows the support part 12. It is designed as a one-piece, elongated structure and has an upper leg 13 and a lower leg 17, which are connected by a preferably curved connecting portion 16.
- the shape of the support part 12 is reminiscent of a bent piece of sheet metal, the legs of which run parallel at a distance and the connecting section of which is strongly curved.
- On the upper leg 13 there are two openings 14, by means of which the supporting part 12 can be screwed to the bars 3 of the chassis 2, see FIGS. 2 and 3.
- On the lower leg 17 there are also two openings 19, which are used to fasten two swivel castors 8 serve on the support part.
- the support member 12 is designed to be flexible so that the upper and lower legs 13, 17 can be moved resiliently against one another. Spring steel or a plastic with resilient properties is suitable as the material for the production of the supporting part 12, the resilient properties of course also being able to be influenced by the shape of the supporting part 12.
- FIG. 3 shows the front end 3 'of a spar 3 with a support part 12 and with a front swivel castor 8.
- the support part 12 and the swivel castor 8 are with the corresponding proportion by weight of the unloaded transport carriage 1 loaded.
- the spar 3 this also applies to the second opposite spar 3, see FIG. 1- has a horizontally arranged screw-on plate 4 which is equipped with a vertical threaded bore 5.
- the upper part 13 of the support part 12 is screwed to the screw-on plate 4 by means of a screw 21 which penetrates the opening 14.
- the upper leg 13 opens into the arcuately curved connecting section 16 pointing in the sliding direction of the transport carriage 1, which then merges into the lower leg 17 arranged parallel to the upper leg 13.
- the steering roller 8 is also fastened to the supporting part 12 with the aid of a screw 22, the screw 22 penetrating the opening 19.
- the opposite steering roller 8 is also fastened accordingly.
- the elasticity and the suspension properties of the supporting part 12 are selected such that the lower leg 17 assumes a horizontal position in the unloaded state of the transport carriage 1, so that the pivot axis 10 of the steering roller 8 is exact is arranged vertically.
- a space 15 is provided in the upper leg 13 above the opening 19 and a space 20 in the lower leg 17 below the opening 14. The same also applies to the other side of the support part 12.
- the free spaces 15, 20 are intended for receiving or inserting assembly tools.
- FIG. 4 shows the arrangement described in FIG. 3, but with the support part 12 now heavily loaded. This state occurs when the transport carriage 1 is loaded and the weight force acting on the steering roller 8 increases.
- the lower leg 17 leaves its original position parallel to the upper leg 13 and, with its free end 18, approaches the upper leg 13 more and more at an increasingly acute acute angle.
- the swivel axis 10 of the steering roller 8 also leaves its vertical Position and inclines with increasing weight load more and more in the direction of slide (arrow) of the trolley 1.
- the angle of inclination ß shown in the drawing is intended to illustrate this changed position.
