Description

[0034] An exemplary embodiment and further advantages of the invention will be discussed below in connection with the following figures. In the drawings:

[0035] FIG. 1 shows a perspective schematic illustration of a known hook connector arrangement;

[0036] FIG. 2 shows a further perspective schematic illustration of the known hook connector arrangement from FIG. 1;

[0037] FIG. 3 shows a perspective schematic illustration of a hook connector arrangement according to the invention;

[0038] FIG. 4 shows a further perspective schematic illustration of the hook connector arrangement according to the invention from FIG. 3; and

[0039] FIG. 5 shows a schematic cross-section through the hook connector arrangement according to the invention at an open end of a conveyor belt.

[0040] The description of the abovementioned figures is given in Cartesian coordinates with a longitudinal direction X, a transverse direction Y oriented perpendicularly to the longitudinal direction X, and a vertical direction Z oriented perpendicularly both to the longitudinal direction X and also to the transverse direction Y. The longitudinal direction X may also be referred to as the depth X or running direction X of the conveyor belt 3, the transverse direction Y as the width Y, and the vertical direction Z as the height Z.

[0041] FIG. 1 shows a perspective schematic illustration of a known hook connector arrangement 1. FIG. 2 shows a further perspective schematic illustration of the known hook connector arrangement 1 from FIG. 1.

[0042] The known hook connector arrangement 1 from FIGS. 1 and 2 has a plurality of structurally identical hook connector pairs 11, each of which comprises two structurally identical hook connectors 10. The two hook connectors 10 of a hook connector pair 11 are connected together by substance bonding in the width Y at two connection points 12. The individual hook connector pairs 11 are spaced apart from one another by distances 13 in the width Y.

[0043] Each hook connector 10 has an open end 14 on the rivet head side and an open end 15 on the rivet foot side, which are connected by a U-shaped bend 16. At the open end 14 on the rivet head side, a rivet 18 is provided in each case which passes through a passage opening 17, opposite this in the height Z, of the open ends 15 on the rivet foot side of the hook connectors 10, and can then be deformed from the outside.

[0044] The individual hook connector pairs 11 are connected together in the width Y by a connecting element 19 in the form of a connecting wire 19, which is arranged by substance bonding on the inside at the open end 14 on the rivet head side of the hook connectors 10. Thereby the known hook connector arrangement 1 is formed.

[0045] FIG. 3 shows a perspective schematic illustration of a hook connector arrangement 1 according to the invention. FIG. 4 shows a further perspective schematic illustration of the hook connector arrangement 1 according to the invention from FIG. 3. FIG. 5 shows a schematic cross-section through the hook connector arrangement 1 according to the invention at an open end of a conveyor belt 3.

[0046] The hook connector arrangement 1 according to the invention, in FIGS. 3 to 5, differs from the known hook connector arrangement from FIGS. 1 and 2 in that, in the hook connector arrangement 1 according to the invention in FIGS. 3 to 5, running parallel to the connecting wire 19, a clamping element 2 in the form of a clamping wire 2 is arranged by substance bonding on the inside at the open ends 15 on the rivet foot side of the hook connectors 10.

[0047] If now a hook connector arrangement 1 according to the invention is arranged at an open end of the above-mentioned conveyor belt 3, and its two open ends 14, 15 are there pressed together in the height Z and riveted (see FIG. 5), the connecting wire 19 and the additional clamping wire 2 press from both sides in the height Z onto the elastomer cover layers 31 of the conveyor belt 3. Thus the elastomer base body 30 of the conveyor belt 3, with the flat textile tension members 32 embedded therein, is also compressed in the height Z.

[0048] In this way, in addition to the force-fit connection previously created by the known hook connector arrangement 1 between the open ends 14, 15, both an increased force-fit connection and an additional form-fit connection are created between the connecting wire 19 and the clamping wire 2, independently of the action of the rivets 18. This may improve both the static and the dynamic connection strength and hence extend the service life of the connection of the open ends of the conveyor belt 3.
