Description

[0037] The invention shall be explained in the following with reference to exemplary embodiments and the drawings, wherein:

[0038] FIG. 1 shows an exemplary embodiment of a first design in accordance with the invention;

[0039] FIG. 2 shows a second embodiment of the invention with a hose-shaped tensioning belt;

[0040] FIG. 3 shows an embodiment of the invention with a hose-shaped tensioning belt, which is designed as an endless hose;

[0041] FIG. 4 shows a further design of the invention with a textile endless belt.

[0042] FIG. 1 shows a first embodiment of the invention in which the fastening apparatus has a band-shaped tensioning belt 1, which is designed as an endless belt, having only individual elastic sections 2. The sections of the tensioning belt 1 in the circumferential direction between the elastic sections 2 are made from a non-elastic material however.

[0043] The elastic sections 2, the number of which can deviate from the number shown here, namely three, wherein at least one elastic section 2 is provided, allow the tensioning belt 1 to be expanded and pulled over the rim edge onto a vehicle rim 11, so that it is braced against the outer circumference of the rim or of the rim bed as a result of the elasticity. This bracing is symbolized by the thick arrow in FIG. 1, wherein the quadruple arrow symbolizes the widening of the tensioning belt 1 for pulling over the rim edge.

[0044] The tensioning belt 1 has a receiving device 3, into which the measuring sensor 10 can be inserted before or after the tensioning belt 1 has been installed on the rim 11, either releasably or non-releasably. The receiving device 3 can, for example, be provided in the form of a base or adapter, as shown in FIG. 1. According to a further embodiment, the receiving device 3 is formed by a pocket of elastic material, for example integrated into one of the elastic sections 2. This is shown schematically by the dotted line in one of the elastic sections 2, wherein the dotted line represents an inlet opening 4, which could also be called an insertion opening, through which the measuring sensor 10 could then be inserted into the corresponding elastic pocket, which is denoted here with reference numeral 5. An embodiment without an inlet opening 4, with a permanently integrated measuring sensor 10 in the elastic pocket 5, is also possible.

[0045] In the embodiment of FIG. 2, the tensioning belt 1 is designed as a belt with two ends 6.1, 6.2, which can be connected to one another in order to clamp the tensioning belt 1. The connection is made, for example, via a closure with two closure halves 7.1, 7.2, wherein the first closure half 7.1 is provided at the first end 6.1 and the second closure half 7.2 at the second end 6.2. As is shown schematically in the detail a of FIG. 2, the two closure halves 7.1, 7.2 form, for example, a magnetic closure 7. If, in this case, the closure halves 7.1, 7.2 are formed in a profiled manner so that they engage with one another to form at least one undercut or a plurality of undercuts, tensile forces can be absorbed particularly securely. If the profiling forms several latching positions, as shown in the detail a, a length-adjustable closure for the tensioning belt 1 is further achieved, which still uses the advantage of undercuts.

[0046] In the embodiment according to FIG. 2, the tensioning belt 1 is designed as an elastic hose 8 which has a hose interior 9 into which a measuring sensor 10 can be inserted via the inlet opening 4. The hose interior 9 can be divided or separated into individual sections in the longitudinal direction of the hose 8, which corresponds to the circumferential direction of the tensioning belt 1. In the exemplary embodiment shown, for example, a seam 12 is provided in order to achieve a corresponding subdivision, so that an elastic pocket 5 for the measuring sensor 10 is formed within the hose interior 9. Alternatively, a design without an inlet opening 4 is also possible.

[0047] In the embodiment according to FIG. 3, the band-shaped tensioning belt 1 is again designed as an elastic hose 8, in the hose interior 9 of which the measuring sensor 10 can be accommodated. Here too, the measuring sensor 10 is introduced into the hose interior 9 again via an inlet opening 4, or the measuring sensor 10 is non-removably accommodated in the hose interior 9 so that the inlet opening 4 can be dispensed with.

[0048] In the design of FIG. 3, the tensioning belt 1 is designed as an endless belt and at the same time the elastic hose 8 is designed as an endless hose, i.e. this time it does not have any subdivision or separation of the hose interior 9. Alternatively, in the case of an endless belt, at least one corresponding partition could also be provided in order to subdivide the hose interior 9 into individual sections, wherein the individual sections are separated from each other. Here too, the inlet opening 4 can be permanently closed or can be dispensed with, depending on the manufacturing method of the hose 8, if the measuring sensor 10 should accommodated in a non-removable manner in the hose interior 9.

[0049] In the embodiment according to FIG. 4, the band-shaped tensioning belt 1 is designed as a textile endless belt 13, which in the circumferential direction of the tensioning belt 1 is elastic at least in sections (see FIG. 1) or over the entire circumference. The endless textile belt 13 is produced, for example, by weaving or knitting.

[0050] Once again, a receiving device 3 is provided for the measuring sensor 10, which can be designed, for example, in the form of a pocket, but alternatively also in the form of a base. Reference is made in this regard to the embodiments according to FIGS. 1 to 3 and in particular to the description there of the receiving devices 3 or elastic pockets 5.
