Abstract

PURPOSE:To obtain applicability to various uses and diversity of external appearance, by fitting a ring member for giving additional function to a portable watch attachably and detachably to the upper internal surface of a rotary bezel ring. CONSTITUTION:At the upper part of the rotary bezel ring 1 fitted rotatably to the upper circumferential edge of a middle 2, a stepped part 1a and a cylindrical part 1b for mounting an interchangeable ring 3 are formed, and the internal wall of the cylinder part 1b is cut into a screw 1c which engages the screw 4a of a ring 4 for fixation threadably. One interchangeable ring 3 selected according to purposes is made to fall on the stepped part 1a from the cylindrical part 1b of the rotary bezel ring 1 and the fixation ring 4 is set threadably on the lower flange 3b to put the interchangeable ring 3 and rotary bezel ring 1 together in one body, so selectively giving the watch a reading function for elapsed time, a reading function for the remaining time, and a waterproof function durable for swimming, etc., according to the equipped ring.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a portable watch side with an exchangeable rotating bezel ring.

A ring is rotatably attached to the periphery of the watch case, and the elapsed time and remaining time can be read from the positional relationship between the time scale and the hour and minute hands, etc. attached to the surface of the ring, or A watch that indicates a specified time is known as a portable watch with a rotating bezel ring.

However, this type of watch is not only limited to reading either the elapsed time or the remaining time depending on the orientation of the scale on the rotating bezel ring, but also cannot be used for other purposes other than this type of use. However, there was a problem in that the ring became almost useless.

In view of these problems, the present invention provides a new portable bezel with a rotating bezel ring that can provide adaptability to various uses and diversity in appearance by attaching a ring suitable for the use in a replaceable manner on the rotating bezel. The purpose is to provide watches.

Therefore, details of the present invention will be explained below based on illustrated embodiments.

1 to 3 show an embodiment of the present invention. In the figures, 1 is a rotating bezel ring rotatably attached to the upper layer of the body 2; , the intersection 11% +1 with the stepped portion 1a on which the exchange ring 5 described later is placed
A cylindrical portion 1b into which the ring 3 and the fixing ring 4 are fitted is formed, and a screw 1c which is screwed into the screw 4m of the fixing ring 4 is cut in the inner wall base of the cylindrical portion 1b. The above-mentioned exchange ring 5 is formed as a crank-shaped ring in cross section, consisting of an upper flange 5a stretched in the inner circumferential direction, a lower flange 5b extended in the outer circumferential direction, and a scale ring 31 (for reading the light passing time). In Figure 3 (a)),
There is a clockwise time scale on the surface of the upper 7 langes SsI, and the scale ring 32 (Fig. 5 (b)) K for reading the remaining time is
A counterclockwise time scale is provided, and the windshield protection ring 53 (FIG. 5 (c)) is protected by covering the surface of the glass 6 from the upper 7 flange 33. The lower flange 5b is configured to be clamped and fixed to the stepped portion 1a of the rotating bezel ring 1 by the pressing action of the fixing ring 4 from above. . In addition, the reference numeral 5 in the figure indicates the rotating bezel ring 1.
6 indicates a glass to prevent the ring from coming off.

Therefore, according to this embodiment, one replacement ring 5 selected depending on the application is replaced with the cylindrical portion 1b of the rotating bezel ring 1.
The replacement ring 5 and rotating bezel ring 1 can be integrated by rolling and mounting the nine rings 31, 52 by dropping the fixed ring 4 onto the stepped portion 11 and screwing the fixing ring 4 onto the lower flange 3b. .5MK, a single portable watch can be selectively provided with &i over-waiting time reading function, remaining time reading function, or windshield maintenance function suitable for mountain climbing, swimming, etc.

In the embodiment shown in FIGS. 4 and 5, the illumination device ring 54 is not directly mounted on the rotating bezel ring 1, and a dial illumination lamp S4C and a battery 34d are provided on a part of the upper surface. For installation, cut a screw 54b on the outer circumferential surface of the ring 34a, and directly screw it into the screw 1cK on the inner surface of the cylindrical portion 1b of the rotating bezel ring 1, thereby integrating the two and rotating the rotating bezel ring 1. In the figure, reference numeral 54 indicates a dial switch.

The present invention has been described above based on an embodiment in which a plurality of replacement rings 5 having a timekeeping function or a protection function are removably attached to the rotating pale ring 1, but it is also possible to provide these rings 3 with only a decorative function. It is also possible to give a single portable watch various changes in appearance by replacing these as appropriate.
It is also possible to give the portable watch a decorative change by rotating the ring to change the angle of the decorative exchange ring. Additionally, if a bayonet type attachment mechanism is used for attachment to the rotating bezel ring 1, it is possible to reduce the thickness of these rotating parts and, by extension, the thickness of the portable watch.

As described above, according to the present invention, the ring member that provides an additional function to a portable watch is detachably attached to the inner surface of the upper part of the rotating bezel ring. By simply preparing the required number of ring members, it is possible to provide a single portable watch with functions according to its intended use, and it is also possible to vary its appearance.
