Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention relates to a rotating bezel for a watch case. In particular,
The present invention relates to a luminous bezel sealing structure of a rotating bezel that is highly decorative and is used for a watch case that requires fashionability.

[Outline of the Invention] The present invention has a rotating bezel structure of a watch case in which a rotating bezel is rotatably mounted, and the rotating bezel is engaged with the watch case by a known structure.

This rotating bezel has a metal bezel inner member on which a plastic bezel outer member that locks in a circumferential direction and a bezel axial direction is locked, and has a non-circular shape on the outer surface wall of the bezel outer member. A luminescent paint that is highly fashionable with decorative variety by forming a luminescent paint embedding hole at the same time as the injection molding of the bezel outer member and filling the luminescent paint and then sealing or sealing the non-circular transparent sealing member by adhesion or welding. It realizes a watch case with a rotating bezel.

[Prior Art] In a conventional rotary bezel structure, as shown in FIG. 6, a rotary bezel body 1 is rotatably engaged with a watch case 6 by a well-known structure. The rotating bezel body 1 is made of metal and has an outer wall 5
The outer wall 5 is provided with decorations such as circumferential streaks.
A circular luminous coating embedded hole 2 is formed in the
The luminous coating 2a is sealed by the circular transparent sealing member 4 for sealing the. On the other hand, the outer peripheral wall of the rotating bezel body 1 is formed with a knurl 7 for facilitating the rotation of the rotating bezel.

[Problems to be Solved by the Invention] However, in the above-described conventional structure, the rotating bezel body 1 is limited to the use of a metal material in order to maintain its function and performance. Since the luminous paint burying hole 2 provided in the above is small in size, it is difficult to perform the drilling process, which requires a long time for the process, resulting in high cost. Secondly, as for the luminescent paint burial hole (luminous scale), originally, in the 12-hour system, 12 luminescent holes are desired, but as mentioned above, it is difficult and costly to drill the luminescent hole 2. As a result, we were unable to meet the demand for designing two or more locations for burying the luminous paint burial holes. Also, since the conventional luminescent paint burying hole 2 and luminescent paint sealing member fitting hole 3 are drilled by a drill, the contour shape of the burying hole is limited to a circular shape, and a non-circular design such as a triangle or a quadrangle is required. However, the restrictions on the design variety were too large, which hindered product expansion.

[Means for Solving the Problems] A rotating bezel structure for a timepiece according to the present invention is a rotating bezel structure for a timepiece including a metal bezel inner member and a resin bezel outer member, wherein the bezel inner member is an outer wall and an outer peripheral wall. A groove is formed in the bezel outer member, the molding resin is injected into the groove of the bezel inner member by injection molding, and is solidified to be locked so as to cover all the outer surface wall and the outer peripheral wall of the bezel inner member. The outer wall of the outer member has one or more non-circular luminescent paint burial holes and a convex contour peripheral wall protruding from the outer wall around the luminescent paint burial holes, and the burial holes are non-circular transparent. It is characterized by being bonded or welded and sealed by a sealing member.

[Embodiment] FIG. 1 shows an embodiment of the present invention.
The inner shape 8 of 1a has a known shape configuration that engages with the case. In the outer wall 13, a plastic bezel outer member 1b is provided with a circumferential detent groove 14 of the bezel outer member 1b, which is solidified after the molten plastic material flows in during outsert injection molding. Place along intermittently. Further, the outer peripheral wall 16 of the inner member 1a of the bezel has an outer peripheral groove.
When the injection molding is performed, a part of the bezel outer member 1b is fitted and solidified by inflow at the time of injection molding, and the bezel inner members 1a and 1b are fixed and locked also in the bezel axial direction. Note that FIG. 2 shows the cross-sectional shape of the bezel outer member 1b in the groove 14 of the embodiment of FIG. 1 in a fitted state.

After the injection molding of the bezel outer member 1b as shown in FIG. 3 is completed using the bezel inner member 1a, the bezel inner member 1a
The bezel outer member 1b and the bezel outer member 1b realize a rotating bezel which is coupled to each other so as not to slip out in the circumferential direction and the bezel axial direction.

Now, in FIG. 3, the outer wall 5 of the bezel outer member 1b
As shown in FIG. 4, a triangular luminous coating embedded hole 2 and a non-circular insertion hole 3 into which the embedded hole sealing member 4 is inserted are arranged, and the embedded hole 4 is filled with the luminous paint 2a and then formed into a non-circular shape. The transparent sealing member 4 made of an inorganic material or plastic is inserted and sealed and fixed by adhesion or welding. The embedding hole 2 and the luminous paint sealing member fitting hole 3 have a triangular shape in this embodiment, but can have any design shape such as a quadrangle. Further, although the buried holes 2 and 3 are provided at one place in this embodiment, two or more places can be appropriately provided. Further, it is possible to design such that a peripheral wall 6 having a design convex contour as shown in FIG. 5 is provided around the buried hole 2. These shapes are easily molded by plastic molding during injection molding. Further, the positioning of the luminescent paint burying hole 2 and the bezel inner member 1 in the circumferential direction is performed by locking the bezel members 1a and 1b in a positional relationship determined by the rotation-stop groove 14.

[Advantages of the Invention] According to the invention described above, the bezel outer member is configured to be locked by injection molding so as to cover the outer surface wall and the outer peripheral wall of the bezel inner member. Since it can be formed, it is possible to easily form various shapes of the luminescent coating buried hole.

Further, by providing a convex contour peripheral wall projecting from the outer wall around the luminescent paint burial hole, the light emitted by the luminescent paint can be made clear, so that a rotating bezel structure for a watch that is brilliant in design can be provided. Is.
