Definitions

the invention relates to a housing for wristwatches.
Vanadium 0.2 - 3%
the object of the invention is to show a housing which, with high functionality, has a high load capacity.
a housing is designed according to the characterizing part of claim 1.
At least the housing part but preferably also the outer cover closing the housing on the underside, consists of hardenable, nickel-free stainless steel, which has a carbon content greater than 0.4% and contains in alloy chrome with a content greater than 12%, molybdenum with a content greater than 0.2% and vanadium with a content greater than 0.2%.
a hardenable steel insert which has a carbon content greater than 0.1%, preferably between 0.1 and 6% and chromium greater than 12%, tungsten greater than 1.0% Contains molybdenum greater than 0.2%, vanadium greater than 0.2%, greater than 0.2% and silicon greater than 0.2%.
the invention is now based on the knowledge that, surprisingly, the aforementioned hardenable steels, despite their magnetizability, are also suitable for the housing of wristwatches if, in addition, the ring surrounding the movement made of the diamagnetic metallic material is inside the housing is provided. It has been shown that the ring accommodating the part of the interior of the housing which accommodates the clockwork can be kept free from a magnetic field which impairs the function and accuracy of the clockwork.
the invention is explained in more detail below with reference to the figure using an exemplary embodiment.
the figure shows a simplified representation of a section through a housing according to the invention for a men's and / or women's wristwatch, together with a clockwork arranged in this housing.
1 is the outer housing of a men's and women's wristwatch, in which the clockwork 2 with the hands 3 and the dial 4 is accommodated, and which on the top side, which is at the top in the figure, consists of a disk or a watch glass 5 Safirglas and is sealed at the bottom by a lid 6.
the axis of the clockwork 2, around which the hands 3 revolve, is labeled A.
the watch glass 5 is inserted in a suitable manner in a groove on the top of the housing and is fastened there, for example by gluing or in another suitable manner.
the cover 6 is fastened by screwing onto the underside of the housing 1, specifically sealed by a sealing or O-ring 7.
a ring 8 enclosing the clockwork 2, in which the clockwork 2 is held.
the ring 8 has an axial height which is equal to or approximately the same as the height of the clockwork 2.
an intermediate cover 9 is provided in the interior of the housing 1, which closes the ring 8 on its side facing the outer cover 6 and, via a further sealing ring 10, the auxiliary housing formed by the ring 8 at the bottom, ie, on the side facing the cover 6 completes.
the intermediate cover 9 lies with its surface sides parallel to the surface sides of the outer cover 6 and parallel to the surface sides of the dial 4 and the watch glass 5 and thus also in planes perpendicular to the axis A of the watch, which is determined by the axis of the hands 3.
the intermediate cover 9 is held on the ring 8 by the fact that this intermediate cover is supported with its side facing away from the clockwork mechanism 2 against the inner surface of the outer cover 6, namely with elastic deformation of the sealing ring 10, so that the intermediate cover 9 is arranged without rattling and rattling is.
the ring 8 With its upper end face in the figure, the ring 8 is supported on the circumferential area of the dial 4, which in turn bears against a collar 1 1, which is formed on the inner surface of the housing 1 in that the cross section of the interior of the housing 1 there Formation of an annular contact surface (collar 1 1) lying in a plane perpendicular to the axis A is reduced towards the top of the housing.
12 with a ring made of an elastic material, for example made of elastic plastic or rubber, which surrounds the ring 8 at its upper end adjacent to the dial 4 and also the axis A and is arranged in a groove 13 of this housing which is open towards the interior of the housing is.
the damping ring 12 forms an elastic mounting of the ring 8 and thus the clockwork 2 and protects this clockwork against external impacts acting on the watch.
a steel of the group X55 CrMo 14, X65 CrMo 14, X90 CrMoV 18, X105 CrMo 1 7 and X 1 10 is specially used to manufacture the housing 1 and the outer cover 6 CrMoV 1 5 and preferably the steels X105 CrMo 1 7 and X1 10 CrMoV 15 are used, these latter steels containing carbon, silicon, manganese, phosphorus, sulfur, molybdenum and vanadium in the following proportion:
the housing 1 and the cover 6 are produced from the solid material by machining, by means of which a blank is first produced.
This blank is then heated in a vacuum oven or in a protective gas atmosphere at a temperature above 1000 ° C., preferably at a temperature between approximately 1030 and 1060 ° C., and then quenched.
the blank thus hardened is then relaxed at a temperature below 200 ° C, ie at a temperature of about 1 70 - 180 ° C over a period of one to two hours.
the housing 1 and the cover 6, which then have a hardness of up to 63 or 65 HRC, can be post-treated on the surfaces, for example by blasting with glass beads, high-gloss polishing, CVD-PVD coating.
a hardenable steel is also suitable for the housing 1 and / or the cover 6, which then has the following proportions of carbon, chromium, tungsten, molybdenum, vanadium, manganese and silicon:
This case-hardenable steel can also be used to produce the housing 1 and the cover 6 with great hardness, although the above-mentioned steels X1 10 CrMoV 1 5 and X105 CrMo 1 7 are preferred.
the intermediate ring 8 which consists of one of the magnetic metallic material consists of a material that displaces existing magnetic lines.
Copper alloys are particularly suitable as materials, especially copper-tin or copper-zinc alloys.
the ring 8 preferably consists of CuZn 40 Al2.
the dial 4 or the disk forming this dial and the intermediate cover 9 are made from the same material as the ring 8, so that the clockwork 2 is completely housed in a housing or in a shield made of the magnetic metallic material.
flat, disk-like rings can also be sufficient, which only partially close the upper and / or lower open side of the ring 8.
