Description

[0042] The invention is described below with the aid of drawings which show several embodiments, in which, schematically:

[0043] FIG. 1 shows a first identification strip according to the invention in a perspective view from above;

[0044] FIG. 2 shows the identification strip from FIG. 1 in a cross section;

[0045] FIG. 3 shows a further identification strip according to the invention in a cross section;

[0046] FIG. 4 shows the identification strip from FIGS. 1 and 2 in a fully mounted state;

[0047] FIG. 5 shows the identification strip from FIG. 3 in a fully mounted state;

[0048] FIG. 6 shows the identification strip from FIGS. 1 and 2 in a fully mounted state in a perspective view from above;

[0049] FIG. 7 shows a further identification strip according to the invention in a perspective view from above; and

[0050] FIG. 8 shows the identification strip from FIG. 7 in a front view.

[0051] FIG. 1 shows an identification strip 2 for an electrical installation, which is provided as a continuous material, as indicated by the freehand cutting line.

[0052] The identification strip 2 has a marking area 4 that is designed to be printed by way of a printing device. The identification strip 4 has a clamping area 6 that is designed to engage in a fastening groove.

[0053] To make the following statements easier to understand, a Cartesian coordinate system is introduced, wherein a longitudinal extension of the identification strip 2 is oriented or measured along the x-axis, a width of the identification strip 2 is oriented or measured along the y-axis, and a height of the identification strip 2 is oriented or measured along a Z direction.

[0054] Accordingly, the marking area 4 extends over a height H1, while the clamping area 6 has a height H2 (FIG. 2). The total height of the identification strip is thus the sum of the heights H1 and H2.

[0055] The marking area 4 and the clamping area 6 comprise a first plastic 8, which is illustrated by the cross-hatching of the cross section shown in FIG. 2.

[0056] The marking area 4 and the clamping area 6 each have adhesion areas 10, 12, 14, 16 which are each formed from a second plastic 18, as shown in FIG. 2 by the hatching of the respective adhesion areas 10, 12, 14, 16.

[0057] The second plastic 18 is more flexible than the first plastic 8 so as to increase static friction and accordingly forms slip protection or prevents slip for the completely mounted state.

[0058] The marking area 4 has a first side 20 having a cover surface 22 to be printed. The adhesion areas 10, 12 of the marking area 4 are formed on a second side 24 facing away from the first side 20 and on the end faces 26, 28 connecting the first side 20 and the second side 24.

[0059] In the present case, the marking area 4 has exactly two adhesion areas 10, 12, which are integrally bonded to the adjoining material 8 as co-extruded strands 10, 12.

[0060] The clamping area 6 has two projections 30, 32 protruding from the marking area 4. A particular adhesion area 14, 16 is arranged on each of the projections 30, 32. The projections 30, 32 are formed integrally with the marking area 4 by co-extrusion and, when viewed in the cross section shown in FIG. 2, extend, starting from the marking area 4, substantially diverging in a V-shape.

[0061] The projections 30, 32 each have an end section 34, 36, at least sections of which are formed parallel to a width extension along the y-axis of the marking area 4. The adhesion areas 14, 16 sit on the end sections 34, 36. The adhesion areas 14 and 16 are accordingly formed on the freely protruding end sections 34, 36 of the projections 30, 32.

[0062] The adhesion areas 10, 12 of the marking area 4, when viewed in the Y direction, are at a greater distance from one another than the adhesion areas 14, 16 of the clamping area 6. The adhesion areas 10, 12 are arranged facing the adhesion areas 14, 16.

[0063] In the present case, the adhesion areas 10, 12, 14, 16 consist of the second plastic 18, while all areas of the identification strip different from the adhesion areas 10, 12, 14, 16 consist of the first plastic 8.

[0064] FIG. 3 shows a further variant of an identification strip 38 according to the invention in a cross section, wherein only the differences from the embodiment described above are discussed in order to avoid repetition, and the same features are assigned the same reference symbols. The identification strip 38 differs from the embodiment in FIG. 2 in that the adhesion areas 10, 12 are offset or stepped with respect to the adjoining material 8 of the marking area 4, such that a shoulder or step is formed.

[0065] FIG. 4 shows the identification strip 2 in a fully mounted state. FIG. 4 thus describes a marking system 40 according to the invention for an electrical installation, wherein the identification strip 2 is fastened to a fastening body 42 and wherein the clamping area 6 of the identification strip 2 engages in a fastening groove 44 of the fastening body 42.

[0066] In the present case, the adhesion areas 10, 12, 14, 16 of the identification strip 2 are each braced against contact surfaces 46, 48, 50, 52 of the fastening body 42. In this way, the identification strip 2 can be reliably fastened to the fastening body 42 in that the adhesion areas 10, 12, 14, 16 increase static friction during contact with the fastening body 42. This also applies to the illustration shown in FIG. 5, in which identification strips 38 known from FIG. 3 are received in the corresponding fastening groove so as to produce a further marking system 54 according to the invention for an electrical installation.

[0067] In order to further clarify the structural configuration of the marking system 40 according to the invention from FIG. 4, FIG. 6 shows a perspective view from above, which shows the identification strip 2 in the fully mounted state on the fastening body 42.

[0068] In FIG. 4-6, hatching of the identification strip in question has been omitted to improve clarity and to clarify the relative arrangement on the associated fastening body.

[0069] FIGS. 7 and 8 show a further identification strip 56 for an electrical installation, which can be provided as a continuous material.

[0070] The identification strip 56 has a marking area 4 that is designed to be printed by way of a printing device. The identification strip 4 has a clamping area 6 that is designed to engage in a fastening groove.

[0071] To make the following statements easier to understand, a Cartesian coordinate system is introduced, wherein a longitudinal extension of the identification strip 56 is oriented or measured along the x-axis, a width of the identification strip 2 is oriented or measured along the y-axis, and a height of the identification strip 2 is oriented or measured along a Z direction.

[0072] Accordingly, the marking area 4 extends over a height H1, while the clamping area 6 has a height H2 (FIG. 8). The total height of the identification strip is thus the sum of the heights H1 and H2.

[0073] The marking area 4 and the clamping area 6 comprise a first plastic 8. The clamping area 6 has adhesion areas 14, 16 which are each formed from a second plastic 18. The second plastic 18 is more flexible than the first plastic 8 so as to increase static friction and accordingly forms slip protection or prevents slip for the fully mounted state.

[0074] The marking area 4 has a first side 20 having a cover surface 22 to be printed.

[0075] The clamping area 6 has two projections 30, 32 protruding from the marking area 4. A particular adhesion area 14, 16 is arranged on each of the projections 30, 32. The projections 30, 32 are formed integrally with the marking area 4 by co-extrusion.

[0076] In the present case, the adhesion areas 14, 16 consist of the second plastic 18, while all areas of the identification strip 56 different from the adhesion areas 14, 16 consist of the first plastic 8.
