    The invention relates to a device for carrying racks or carrying containers with at least two rollers or wheels respectively arranged laterally of the supporting frame or carrying container for an optionally carrying or rolling transport of the supporting frame or carrying container, according to the preamble of claim 1.
    From the prior art support frames or carrying containers for an optional carrying or rolling transport as so-called " trolleys " known, which are provided on the underside of the support frame or carrying container with small wheels or rollers, and are equipped centrally with an extendable handlebar. The load can thus be carried on the back or pulled makeshift. In driving position, this type of " trolley " design-related several disadvantages. For example, the small diameter of the wheels or rollers allows only driving on very smooth floors such as airports and train stations. Furthermore, well-known " trolleys " poor handling characteristics during rolling transport, in particular, they tend to tilt easily. By positioning the wheels or rollers at the bottom of the " trolley " In addition, in driving position with the handlebar pulled out, it is still approximately 30% of the total weight of the trolley. worn by the user.
    In DE 297 10 339 U a collapsible handcart is described on which a backpack can be attached to the front resting, the back remains free with the straps. The wheels are folded down when worn. The construction also has several disadvantages. For example, the backpack can be attached to the handcart with its front lying on it, so that loading and unloading of the backpack is only possible when disassembled. Furthermore, the distance between the wheels to each other is significantly smaller than the height of the backpack, which leads to an unstable driving especially when driving on uneven ground. Also, a positioning of the center of gravity of the backpack vertically above the axle point of the wheels, which allows a largely load-free driving will not be able to accomplish in the rule.
    In US 7111851B a handcart is described, and in WO 04 096 621 A a cart pulled by means of a hip belt for transporting loads, both of which allow collapse of the structure for better stowing thereof. However, the cars are each designed as a handcart with a drawbar and not suitable for carrying loads on the back. Furthermore, the wheels are attached to the lower end of the structure. A part of the load must therefore be worn by the user at the end of the drawbar, so that a load-free driving is thus possible only to a very limited extent. 2.13
    The object of the invention is thus to realize a device for carrying racks or carrying containers, which not only allows a quick and convenient conversion from the carrying position to a driving position, but which is also suitable for use on uneven ground.
    These objects are achieved by the features of claim 1. Claim 1 relates to a device for carrying racks or carrying containers with at least two, each side of the support frame or carrying container arranged rollers or wheels for an optional carrying or rolling transport of the support frame or carrier, is provided in accordance with the invention, that the rollers or wheels respectively a chassis are mounted, which is pivotally mounted on the support frame or carrying container from a support position to a driving position about a pivot axis, wherein the Radachsabstand the at least two laterally arranged rollers or wheels in the driving position is greater than in the supporting position. The arrangement of the wheels or rollers on a pivoting chassis not only allows a convenient for the transport on the back storage of wheels or rollers, but also a rapid conversion, as will be explained in more detail. A rapid conversion from the carrying position to the driving position is important because, according to experience, long conversion periods prevent the possibility of conversion from carrying to driving positions actually being used in practice. Furthermore, it is provided according to the invention that the Radachsabstand the at least two laterally arranged rollers or wheels in the driving position is greater than in the supporting position. This feature allows good handling characteristics especially on uneven ground. It turns out, namely, that the poor usability of carrying racks or carrying cases for rolling transport on uneven ground is caused in particular by the high lateral tilting danger. This risk of tipping is inventively reduced by the fact that the Radachsabstand can be increased for the driving position. In particular, the Radachsabstand the laterally arranged wheels or rollers can also be increased so that it exceeds the width of the support frame or carrying container in the driving position. Even with slight, lateral skew thus remains the focus of the support frame or carrying container in its vertical projection within the Radachsabstandes, so that a lateral tipping more difficult and better driving characteristics are achieved. For a rapid conversion from the carrying position to the driving position, it is proposed that the at least two rollers or wheels arranged at the side of the supporting frame or carrying container are connected via a wheel axle which runs parallel to the pivot axis of the running gear. The common axle allows about a foot-operated operation of the chassis of the two side wheels or rollers, so that the pivoting movement can be easily accomplished. In particular, the wheel axle in the carrying position in the range of 3/13

    Be stored front of the support frame or carrying container, and in the driving position in the region of a rear side of the support frame or carrier, wherein the wheel axle pivots in the course of pivotal movement of the chassis from the support position to the driving position about a bottom of the support frame or carrier. The back of the support frame or carrying case is that side which is in the carrying position in contact with the back of the wearer. When carrying transport thus the wheels or rollers are away from the back mounted on the front. For a conversion to the driving position, the support frame b2w. only place the carrying container on the ground and lift it with the foot over the wheel axle when fixing the wheel axle. This conversion is thus to accomplish quickly and without great effort.
    The practical use and the conversion from the carrying position to the driving position is facilitated by the chassis is connected to the support frame or carrying container via a, provided with a dead center joint. The carrying position and the driving position represent equilibrium positions in which the chassis remains stable. In a conversion from approximately the supporting position to the driving position, only the dead center position of the dead center spring is overcome, and the chassis automatically assumes the equilibrium position of the driving position in a further consequence.
    Since according to the invention the Radachsabstand is to be increased, may be provided that a coupled with the pivotal movement of the chassis of the support position in the driving position Radachsenauszug is provided, the Radachsabstand in the course of pivotal movement of the chassis from the support position to the driving position in a Swivel axis parallel extension direction enlarged. The pivoting movement and the enlargement of the Radachsabstandes thus carried out simultaneously in the same movement process, whereby the conversion can be accomplished even faster. According to one embodiment, it is proposed, for example, that the Radachsenauszug includes a distance-reducing restoring element, and a distance-increasing cable, which is guided in the course of pivotal movement of the chassis of the support position in the driving position via a clamping disc. The cable is thus shortened in the course of the pivotal movement of the chassis of the supporting position in the driving position, whereby a Ausschubbewegung the respective wheel can be effected. In the course of the pivotal movement of the chassis from the driving position to the carrying position of the cable, however, is extended again, and the return element restores the original, smaller Radachsabstand. The Radachsenauszug can be provided on one or preferably also on both wheels or rollers to ensure a symmetrical arrangement of the wheels or rollers with respect to the center of gravity of the support frame or carrying container. 4/13 · Λ · · < Τ · ·
    The invention will be explained in more detail with reference to an exemplary embodiment with reference to the accompanying figures. It shows the

    Pivoting of the chassis from the carrying position to the driving position with simultaneous extraction of the wheel axle,
    Fig. 4 is an enlarged view for explaining a Ausiuhrungsform of
    Radachsenauszugs, and the
    Fig. 5 shows a Ausiuhrungsform the device according to the invention in driving position with hip belt.
    In Fig. 1 and Fig. 2, an embodiment of the invention for a support frame 1 or carrying container 12 is shown, on the underside of a pivotable about two horizontal pivot points landing gear 2 is arranged. The two pivot points define a pivot axis 6 of the chassis 2. The chassis 2 can be pivoted between a carrying position 7 (FIG. 1) and a driving position 8 (FIG. 2). In the carrying position 7, the chassis 2 is located on a front side of the support frame 1. The wheels 3 are in each case laterally adjacent to the support frame 1. Although driving on uneven terrain requires wheels 3 of comparatively large diameter, in this position larger wheels 3 find space without hindering the user in carrying the support frame 1.
    2 shows the device according to the invention after swiveling the chassis 2 into the driving position 8. The center of gravity of the load lies largely vertically above the wheel axle 4 of the chassis 2, as indicated in FIG. 2 by means of the vertical auxiliary line. A fine adjustment of the load distribution on the wheel axle 4 can be done by the selected length of the extension of the handle bar 9. This allows a largely load-free driving. The user must overcome only the rolling resistance of the wheels 3 when pulling the support frame 1 or carrying container 12 substantially.
    3 shows the pivoting of the chassis 2 between the supporting position 7 and the driving position 8. At the same time the Radachsabstand the wheel axle 4 by a 5/13 ··

    Radachsenauszug 5 enlarged in the indicated direction of the arrow, which extends in the direction of the wheel axle 4 and thus parallel to the pivot axis 6. In the reverse process, the Radachsabstand the wheel axle 4 is reduced again. The extension of the Radachsenabstandes reduces the risk of tipping during rolling transport of the support frame 1 and carrying container 12, especially on uneven terrain. For a quick conversion of the support position 7 in the driving position 8, the two, each side of the support frame 1 or carrying container 12 arranged rollers or wheels 3 are connected via a wheel axle 4 which is parallel to the pivot axis 6 of the chassis 2. The common axle 4 allows about a foot-operated operation of the chassis 2 of the two side wheels 3, as indicated in Fig. 3, so that the pivoting movement can be easily accomplished. For a conversion to the driving position 8, the support frame 1 or the carrying container 12 is only parked on the ground and to lift when fixing the wheel axle 4 with the foot about the wheel axle 4. This conversion can thus be accomplished quickly and without great effort. The chassis 2 is connected to the support frame 1 or carrying container 12 via a, provided with a dead center spring 15 joint (see also Fig. 4). The supporting position 7 and the driving position 8 represent equilibrium positions in which the chassis 2 remains stable. In a conversion from about the supporting position 7 in the driving position 8, only the dead center of the dead center 15 is overcome, and the chassis 2 automatically takes the equilibrium position in the driving position 8 in a further consequence.
    4 shows a preferred embodiment of the Radachsenauszugs 5 by means of a cable 13. By the pivoting of the chassis 2, the cable 13, which is guided over the tight clamping disc 14, tightened. The provided with the cable 13 Radachsenauszug 5 is thereby pressed against the restoring force of the return element 16 together with the corresponding wheel 3 to the outside (with reference to FIG. 4 to the left). In the reverse process, the wheel 3 is brought back into the starting position by means of the return element 16 of the Radachsenauszuges 5. The dead center 15 spans the chassis 2 in the respective end positions and causes the swinging of the chassis 2 jumping into the respective opposite position.
    FIG. 5 shows the pulling of the support frame 1 or carrying container 12 by means of a hip belt 17. The handle 10 attached to the pull-out handle bar 9 is equipped with a coupling 11 for this purpose. This allows attachment to the user-worn hip belt 17. The hands of the user remain when pulling the support frame 1 or carrying container 12 thus free. By means of the coupling 11, the supporting frame 1 or the carrying container 12 can also be mounted on a bicycle and the like.
