(6) FIG. 5 shows two hollow support profiles arranged one above the other for changing of the height.

DETAILED DESCRIPTION

(7) A support according to the invention is represented in FIG. 1 in three dimensional shape, which embodies a very narrow floor conveyor 1 when fitted with wheels. The view therefore focuses primarily on the bottom side of the support 2.

(8) The hollow profile 3 is clearly recognizable as an extrusion profile, preferably made of aluminum or an aluminum alloy. Alternatively and graphically represented in the same way, it could also be a pultrusion hollow profile made out of fiber reinforced plastics. The view of the end face allows for the recognition of the hollow spaces 4. They are surrounded on the outside by the wall 5 and in this embodiment example can also comprise struts 23 for reinforcement of the hollow profiles 3. The at least one hollow space 4 can moreover be filled with a material for reinforcement of the support 2.

(9) The wall 5 comprises a depression 6 that extends over the whole length of the hollow profile length. The contour of the depression is precisely adapted to the axle 9 of the wheel 8. The profile of the depression could also be configured in such a way that a bearing of the wheel 8 could also be accommodated therein. In this embodiment example the wheel axles are fixed by means of tabs 13, however optionally still rotatable.

(10) FIG. 1 illustrates a support 2, that is fitted with a total of four wheels 8, two on each side, at precisely the distance of the track gauge of the track, upon which the floor conveyor provided with the support is intended to travel. This unit already represents a narrow floor conveyor.

(11) FIG. 2 illustrates a longitudinal cross-section through the support 2 according to FIG. 1 and on top of that through one wheel (on the left hand side). The narrow floor conveyor 1 therefore has four wheels 8 (of which only 2 are visible) and one weight bearing surface 10. The recess 7 for a part of the wheel 8 in the hollow profile 3 can be better recognized in this view. The recess 7 can also be provided with an encapsulation 15 to the hollow profile 3, so that no contamination from the wheels can make its way in the hollow profile 3. The axles 9 of the wheel 8 are positioned precisely in the depression 6. A pressure or force sensor 14 is moreover indicated on the right hand side, with which sensor the load on the floor conveyor can be determined.

(12) The cross-section through the wheel including the wheel axle should represent a possibility of how the wheel 8 is arranged in the depression 6. A clamping device 12 is thereby indicated, which with the tightening of a screw brings the axle to tightly fit against the side walls of the depression. The tab 13 further ensures against a falling out of the wheel from the depression. The wheel itself rotates on a small roller bearing 19 on the axle 9.

(13) The advantage that the concavely turned wheel circumference 18 offers when it is in contact with a round track 11 distributed by the applicant can be recognized in FIG. 3. Notwithstanding that the track can be countersunk into the ground and does not represent a trip hazard or obstacle, the wheel 8 is nonetheless guided safely and stably in the trackway. Even the heaviest loads can be safely transported on the thus created lightweight floor conveyor with this arrangement.

(14) In order to show the variety of possible applications of the support 2 according to the invention, two such supports 2.1 and 2.2 are illustrated in FIG. 4 provided with a support plate 17. With corresponding centering and connecting elements which are not shown, a floor conveyor 1 with a large conveying surface can in this way be created. The connecting elements can be fastened, for example, with slot nuts in the undercut grooves 16 present on the hollow profile 3.

(15) FIG. 5 illustrates that the height of the floor conveyor 1 can also be changed via the hollow profiles 3, namely by preferably placing same hollow profiles 3, 3.1, 3.2 on top of each other and also fixing them with connection tabs 22, which are, for example, fastened by means of slot nuts in undercut grooves 16.

(16) Since the entire floor conveyor 1 has become a relatively light vehicle due to the use of hollow profiles, even if it is not carrying a load, it can be moved by only one person away from the tracks 11 with the gauge S. For this purpose, in this embodiment example according to FIG. 5, additional conveyor rollers 20 and a handle 21 are attached to the floor conveyor. With the handle, the floor conveyor is raised on one side until the rollers sit on the hall floor and the wheels 8 are lifted from the track 11. The floor conveyor 1 can then be pushed manually to another location.

(17) The hollow profile 3 can itself represent the support 2. Furthermore, the hollow profile 3 overlaps both tracks. The hollow profile 3 itself thus has a length that overlaps the track gauge of the tracks 11.

(18) The support 2 is preferably configured as a single piece and is manufactured without seams.
