Description

[Detailed Description of the Invention] The present invention relates to a frame structure of a watch.
Conventionally, when a thin watch mechanism body is attached to a frame body having a large depth and a case back, a gap is created due to the step between the back surface and the watch mechanism body. For this reason, it was difficult to operate the needle turning knob, and there was also the problem that the battery could be accidentally inserted into the frame through the gap when replacing the battery. Therefore, when the depth of the frame is large, a thick watch body is inevitably used, resulting in poor compatibility.

The present invention solves the above problems and provides a timepiece frame structure that allows use of various timepiece mechanical bodies regardless of the depth of the frame.

Embodiments of the present invention will be described in detail below.

In Figures 1 to 3, 1 is the frame of the clock;
Front frame 2, facing 3, glass edge 4, front glass 5,
It consists of a dial 6, a back cover 7, etc. The endpaper 3 is screwed to the front frame 2 with the front glass 5 facing the front side and the glass edge 4 nailed to the front. The back cover 7 has a transparent center hole 7a in the center, and is screwed to the front frame 2. Reference numeral 8 denotes a clock mechanism body, which is nailed to the back of the endpaper 3. The pointer shaft of the timepiece mechanical body 8 protrudes from the front surface of the dial plate 6, and the pointers 9 are press-fitted therein. On the back of the watch mechanism body 8 is a flat hand turning knob 8a.
is installed. 8b is a battery holder. 10
is a frame surrounding the machine body, which is attached to the facing 3 of the frame 1. This attachment is performed by a protruding piece 10a that is inserted into an engaging portion of the facing 3, and a claw portion 10b that engages with a locking claw of the facing 3. The mechanical body surrounding frame 10 has a mounting hole 10c for the watch mechanical body 8 in the center thereof. The mechanical body surrounding frame 10 is formed with a connecting surface 10d that is close to the outer periphery of the watch mechanical body 8 from the rear side of the back cover 7 of the frame body 1.
0d is an inclined surface in this embodiment. Therefore, even if there is a large level difference between the back of the watch mechanical body 8 and the back of the back cover 7 of the frame 1, the watch mechanical body 8 and the back cover 7
The space between the two is covered by the inclined connecting surface 10d, and there is no gap. Therefore, a battery (not shown) can be easily attached to the battery holder 8b of the watch mechanism body 8, and the watch mechanism body 8 is installed in a depressed state from the back of the back cover 7 of the frame body 1. The battery will not be accidentally inserted into the gap between the back cover 7 and the back cover 7. Further, since the flat oblique turning knob 8a can be rotated by placing a finger along the connecting surface 10d of the machine body surrounding frame 10, the outer peripheral portion thereof can be rotated, so that the needle turning operation can be performed easily.
Furthermore, it also prevents dust from entering the inside of the frame 1.

Next, another embodiment of the present invention will be described with reference to FIG. Reference numeral 11 denotes a mechanical body surrounding frame, which is located around the watch mechanical body 12, and has a hole 11a in the center.
is provided. The machine body surrounding frame 11 is screwed together with the back cover 14 of the frame body to attachment bosses 13, 13 provided on the end face of the frame body. Reference numeral 11b denotes a connecting surface of the mechanical body surrounding frame 11, which is closer to the outer periphery of the watch mechanical body 12 than near the back surface of the case back 14, and is formed of a concave curved surface. In this embodiment as well, the gap between the watch mechanical body 12 installed in a depressed state and the outer periphery of the back cover 14 of the frame is the same as that of the mechanical body surrounding frame 1.
Since it is covered by the first curved connecting surface 11b, it has the same effect as the previous embodiment.

As described above, according to the present invention, even if a thin watch mechanical body is attached to a frame with a large depth, battery replacement and hand turning operations can be easily performed. Further, it is possible to prevent dust from entering the inside of the frame, and the appearance can be finished beautifully. It also has great effects, such as excellent compatibility between watch mechanisms.
