Definitions
- the present invention relates to a wrist-watch casing assembled by means of screws which connect a casing back to a central casing body or a bezel to a casing body.
- An object of this invention is to provide a wrist watch casing which can have a threaded bore in a bezel or casing body, even if it is made of a material such as stainless steel, cemented carbide and ceramics, characterized by hard machinability.
- FIG. 1 is a cross-sectional view of a blind bore and a metal coil to be inserted into said bore, according to an embodiment of this invention
- FIG. 2 is a cross-sectional view of a threaded bore formed by means of this invention, and a screw cooperating with this bore;
- FIG. 3 is a cross sectional view of a screw threaded connection according to this invention.
- FIG. 4 is a front view of a wrist-watch casing embodying the present invention.
- FIG. 5 is a cross section of the watch casing taken along the line AA of FIG- 4.
- the wrist watch casing has'a bezel 2 with threaded bores l and a one-piece type casing'body 3 having through'going bores 6 through which-screws 5 arethreaded to; the bores 1 so that the bezel 2 is tightly connected to the casing body 3 to maintain a waterproof seal.
- a glass plate 7 is rigidly supported through a packing ring 8 to the front surface of the casing body 3 by pressure from the bezel 2 alongall'of the edges of the-glass plate 7.
- the wrist-watch casing is separated to two pieces, a center casing body 9 and an inner body 12.
- the threaded bores l are formed in the center casing body 9, into which are inserted screws 5 each passing through a bore 11 formed at the peripheral portionof a casing back 10.
- the inner body 12 is supported tightly to a bezel portion integrally formed with the center casing body 9 by the compression by casing back 10 of body 12 via a packing ring 13.
- a casing back 10 is integrally formed with an inner body 12 and separates from an attaching ring 14.
- attaching ring 14 has through bores 15 through-going which screws 5 are passed to be threaded into threaded bores '6 formed in a center casing body 9, so that the casing back 10 is fixed to the center casing body 9 together with a glass plate 7 and a packing ring 8.
- FIG. 8 depicts an embodiment of the wrist-watch cas- I ing of a screw-back type.
- a casing back 10 is threaded to a large threaded bore 6 formed in the back portion of a center casing body 9.
- a screw 5 is integrally formed with the casing back 10, and the threaded bore 6 is produced by the coil device men-
- FIG. 6 is a cross section similar to FIG. 5 of another embodiment of this invention in which the watch casing is sectioned along a line similar to line AA in FIG. 4;
- FIG. 7 is a cross section similar to FIG. 5 of a furtherembodiment of this invention in which the watch casing is sectioned along a line similar to line AA in FIG. 4;
- FIG. 8 is a cross section similar to FIG. 5 of still ,another embodiment of this invention in which the watch casing is sectioned along a line similar to line AA in FIG. 4.
- a blind bore 1 is formed in a bezel 2 (shown in FIGS. 4 and'5) or a casing body 3 (shown in FIGS. 6 and 7).
- the bezel 2 or casing body 3 is made of stainless steel and the bore l-has a circular inner wall to be smooth.
- a stainless steel coil tightly wound ie with successive turns in axial contact
- fusing alloy for example, nickel phosphide.
- The'plated layer may have a thickness of approximately 10 microns.
- Said plated coil 4 is tightly inserted into said bore 1 and heated at a temperature of about l, C in a nonoxiding' furnace so that'the alloy is fused'in the bore 1 thereby to bond the coil, as a threaded portion, in the bore 1.
- the diameter of the coil 4 may be slightly less tioned above.
- the blind bore 1 may be coated with nickel before the insertion of the coil 4 in the case in which the blind bore 1 is formed by means of erosion, electro-beam, su-
- a wrist-watch casing comprising: a casing-member, a bezel member and a back mem ber interconnected to'define a watch-casing strucsaid members-is made of stainless steel and said coil is composed of stainless steel coated with nickel phosphide fused to the wall of said bore.
