BRIEF SUMMARY
BACKGROUND OF THE INVENTION
This invention relates to a watch-band with a plurality of links detachably linked together, the links having a middle part which on the one side is provided with at least one first extension, forming a female part, and on the other side with at least one second extension, forming a male part, for receiving a connecting element, the first and second extensions having bores. The manufacture of the initially mentioned watch-bands of metal, particularly of steel, known so far entails relatively high costs since the bores in the extensions of the watch-band links as well as the connecting element, designed as a rod holding together two successive links, must be manufactured with great precision. The rod has to be held very securely through the bores in the extensions.
SUMMARY OF THE INVENTION
It is the object of the present invention to create a metal watch-band which can be manufactured with considerably lower manufacturing costs than the known metal watch-bands of the state of the art. The bores in the extensions of the watch-band links as well as the connecting element should not have to be manufactured very precisely. Moreover, in contrast to the subject matters of U.S. Pat. No. 3,837,163, of French Patent No. 2 693 355 and of German Patent No. 2 040 343, an additional aesthetic effect should be attained. This is achieved, according to the invention, in that in the area in which the female part and the male part of two links overlap at least one visible elastic element is provided between the extensions for holding the connecting element.
BRIEF DESCRIPTION OF THE DRAWINGS
Example embodiments of the invention and their application will be explained more closely in the following description with reference to the attached drawings. Shown are:
FIG. 1, two links of a first example embodiment of the metal watch-band with the pin and the rubber rings for connection of the links;
FIG. 2, a top view of four assembled links of the watch-band;
FIG. 3, a section along line III--III of FIG. 2; and
FIG. 4, two links of a second embodiment example of the metal watch-band with the pin and the rubber rings for connection of the links.
FIG. 5 shows in perspective a view of a link according to a second embodiment.
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
Referring to FIG. 1, each; link 1 of the metal watch-band, except the two which are fastened to the watch, has a central middle bar 2 and two outer extensions 3 and 4 adjoining outside thereon, running approximately perpendicular to the middle bar 2, which form the female part. On the side opposite the outer extensions 3 and 4, the middle bar 2 is provided with inner extensions 5 and 6, which form the male part. The outer extensions 3 and 4 as well as the inner extensions 5 and 6 are provided in their outer area with bores 7, 8, 9, 10 running parallel to the middle bar 2. Adjoining the bores 7, 8, 9 and 10 are slots 11, 12, 13, 14. The second link 15 is designed the same way as the first link 1. To connect the two links 1 and 15, a rubber ring 16 is placed between the inner extensions 17 and 18 of the second link 15. Two rubber rings 19 and 20 are placed laterally on the extensions 17 and 18, the link 15 being fixed to the link 1 in such a way that the inner extensions 17 and 18 of the second link 15 are situated between the outer extensions 3 and 4 of the first link 1, and the links partially overlap in the horizontal plane when viewed from above. Then a cylindrical metal pin 21 is pushed through the bore 7 in the outer extension 3, through the rubber ring 19, through a hole 22 in the inner extension 17 of the second link 15, through the rubber ring 16, through a hole 23 in the inner extension 18 of the second link 15, through the rubber ring 20 and through the bore 8 in the outer extension 4 of the first link 1. By of this configuration it is made possible that the bores 7, 8, 9 and 10 in the outer and inner extensions of a watch-band link do not have to be made precisely. They do not have to be cylindrical and can vary in dia
