Description

[Detailed Description of the Invention] The present invention relates to the structure of a display section of a portable timepiece such as a wristwatch, a ring watch, or a pocket watch.

Conventionally, this type of display structure has been such that the outer diameter B of the movement is smaller than the cutting diameter A, as shown in Fig. 5, and the upward adjustment of the movement is performed on the body via the dial. Ta.

That is, 101 is a body, 102 is a cover glass, 1
03 is a dial support ring for positioning the movement 104 in the radial direction, 105 is a dial plate, 106 is a middle frame for pushing the movement 104 upward and fixing it by means of a back cover 107, and 108 is for ensuring waterproofness of the watch. 109 is the minute hand, and 110 is the hour hand.

In this case, when comparing the diameter A of the barrel 101 and the diameter B of the portion of the movement 104 that contacts the dial 105, the diameter B of the movement is much smaller than the diameter A. However, since the upper direction of the movement 104 is determined by the dial 105, the dial 105 must have high strength and hardness, and its thickness must be around 0.5 mm, and its material is metal. had to be centered on.

Furthermore, over the years, the dial 105 itself has become deformed and damaged due to the movement of the watch.

In recent years, there has been a demand for thinner watches, but conventional structures have not been able to fully satisfy this demand.

The present invention satisfies these requirements. Examples of the present invention will be described below.

Figure 1 is an assembled sectional view of the main part, Figure 2 is an assembled sectional view of other important parts, Figure 3 is an assembled plan view of the main part, and Figure 4 is the main part of the middle frame to which the dial is fixed. They are a sectional view a and a plan view b of a main part.

In each figure, 1 is stainless steel, brass, 14k gold,
The body is made of 18-karat gold or the like, 2 is a cover glass made of crystal glass, sapphire glass, plastic, etc., and the end surface 2a is the glass guide shape part 1a of the body 1.
is fixed with adhesive. Reference numeral 3 denotes a parting plate which is inserted into the parting plate guide part 1b of the body 1 from below and fixed by adhesive.
It is glued and fixed to the bottom of the. On the other hand, trunk 1 lower part 1
A back cover 4 is disposed at d, and is fixed to the body 1 with a plurality of back cover fixing screws 5. Reference numeral 6 denotes a movement, which contains a series of quartz watch components such as a battery 7, a crystal oscillator, and a frequency divider, and displays the time using an hour hand 10 and a minute hand 11 on an hour wheel 8 and a cylinder pinion 9, respectively. 12 is a winding stem, 13 is a reuse, and 14 is a winding stem packing.

Further, 15 is a middle frame, and 16 is a back cover gasket.The gasket 16 is clamped between the back cover 4 and the body 1, and also has the role of pushing up the middle frame 15 and the movement 6 and holding them in the body 1, respectively. ing. 17
is the dial.

In this embodiment, a rectangular model is constructed as shown in FIG.

Now, I will explain the inner frame and dial in more detail. Middle frame 15
In the case of the embodiment, it is made of electromagnetic soft iron material such as pure iron or silicon steel, and the front shape is approximately square (see Fig. 4b), and is arranged between the outer periphery of the movement 6 and the inner frame guide portion 1c of the body 1. has been done. Therefore, the middle frame 15 has an anti-magnetic effect on the movement 6. Protrusions 15d (deformable when pushed into the movement 6) are formed in places on the inner periphery of the movement 6, and are pushed into the outer periphery of the movement 6 and fixed thereto. The protrusion 15d may be a smaller protrusion than shown, or the movement 6
It may be placed on the side. A stepped portion is formed on the upper surface of the middle frame 15, and a dial 17 is disposed thereon. The dial plate 17 is extremely thin and has a thickness of 40 .mu.m in the embodiment, but may be 10 to 200 .mu.m or about 300 .mu.m. Considering the strength, hardness, etc., it is desirable to manufacture the dial 17 with such a thin thickness by electroforming.
In this example, it was manufactured by electroforming Ni.
In that case, Hu: 600±100, which is convenient for coating, etc.
It also has sufficient strength. The material may also be a Ni-Co alloy (for example, 10 to 35 mt% Co). A mark or the like is printed or otherwise displayed on its surface. Of course, ordinary roll-rolled material or the like may also be used.

This dial plate 17 is fixed to the upper inner surface of the middle frame 15. The dial mounting surface 15c of the middle frame 15 is the middle frame 1
5 An extremely thin dial plate 17 is formed over the entire surface.
by fixing it over the entire outer circumference of the dial plate 17.
It is designed to be effective in preventing deformation, damage, etc.

In this embodiment, the fixing method is to use an adhesive and apply it to the entire surface of the dial mounting surface 15c.

The planar positioning of the dial 17 is performed at the outer periphery of the dial mounting surface 15c of the inner frame 15 and the outer periphery of the dial 17. Also, although the upper surface of the outer periphery of the middle frame 15 and the upper surface of the dial 17 are approximately at the same height, the upper surface of the outer periphery of the middle frame 15 touches the body 1, so the upper surface of the dial 17 is slightly lowered. The upper surface of the dial 17 may be positioned so that the upper surface of the dial 17 does not touch the body 1, or the upper surface of the dial 17 may be made to protrude from the upper surface of the outer periphery. In this way, the dial 17 is fixed to the inner frame 15, and the inner frame 15 is inserted into the movement 6, so that the dial 17 is attached to the movement 6. Middle frame 15 and movement 6
Although the positioning in the plane direction is performed at the outer circumference of the movement 6 and the inner circumference of the middle frame 15, it may also be carried out using several protrusions and recesses. In addition, middle frame 1
5 and the movement 6 are pushed in in the above embodiment, but may be fitted loosely. Also, the fixation between the dial plate 17 and the middle frame 15 is limited to the middle frame 1.
5, the outer periphery may be partially caulked, attached using pins, screws, etc., or welded, and the fixing location may be the inner periphery or outer periphery of the middle frame 15. This middle frame 15 is inserted from below the body 1, and the movement 6 is positioned in a plane.

Protrusions 15b are also provided at appropriate locations on the outer periphery of the middle frame 15, and are inserted into the inner wall of the body 1 without any gaps. The protrusions 15d and 15b are for adjustment, and their size,
The shape and number are selected appropriately. (The movement 6 and the inner frame 15 inserted into the body 1 may be compressed by the back cover 4 arranged below. It is pressed upward by the back cover gasket 16 and fixed to the barrel 1. On this occasion,
At least a part of the outer circumference of the movement 6 contacts the parting plate 3 via the dial 17, and the parting plate 3 supports the above-mentioned pushing force or large force due to disturbance, so even if the dial 17 is thin, The dial 17 is not deformed or damaged. or,
Since the area delimited by at least a straight line passing through the center of the battery 7 is located outside the parting plate 3, the parting plate supports the pushing up force by the gasket 16 and the large force of disturbance, and the parting plate supports the dial plate 17. No damage will be caused. To explain this point in detail, in FIGS. 1 and 3, first, the parting plate 3 has a parting part 3a at its inner end that forms the parting shape of the dial plate 17, and the cover glass 2 is arranged above the parting part 3a. However, the outer end shape portion 3 of this parting plate 3
b approximately coincides with the parting plate guide portion 1b of the trunk. A movement 6 is positioned below this partition plate 3 over almost the entire area in a plane. The outer end shape portion of the movement 6 is shown as 6a.

This outer end shape portion 6a substantially coincides with the movement guide shape portion 15a of the middle frame 15. The outer end portion 6a of the movement 6 may cross the upper wall of the stepped portion 1f of the body 1 in the left and right positions as shown in FIG.

Dial plate 17 is between this parting plate 3 and movement 6.
is sandwiched. 3c is an abbreviation die-cut on the upper surface of the parting plate 3, and is placed at the 12, 3, 6, and 9 o'clock positions.

Further, the external shape of the battery 7 is shown as 7a. The battery 7 is sandwiched between the dial 17 and is perpendicular to the upper direction by the parting plate 3, but the perpendicular area of the parting plate 3 is approximately 3/4 of the battery area, or in the case of the battery external shape 7a. It has an angle of 270° or more around the battery center 7b.

In this case, the contact position of the parting plate 3 may be set at the outermost periphery beyond the straight line passing through the battery center 7b, or at least at the center of the battery 7. It is.

As described above, according to the present invention, the cover glass is adhesively fixed to the glass guide shape part of the body and the end face part of the cover glass, and is also adhesively fixed to the lower face part of the cover glass, the parting plate guide part of the body, and the stepped part. By adhesively fixing the parting plate to the upper part of the parting plate, a reliable and strong adhesion can be obtained between the body, parting plate, and cover glass, and the cover glass is adhered to the glass guide shape part provided on the upper part of the body. By being fixed, the entire display structure of the watch can be made thinner.

In addition, since the abbreviations are formed using diamond cuts on the upper surface of the parting plate, the upper part of the parting plate does not bulge, and the position can be displayed on a flat surface. It has an excellent display structure,
It also has the effect of making the display structure of the watch thinner.

In addition, the dial is sandwiched between the lower surface of the parting plate and the upper part of the movement containing the battery through the back lid gasket due to the pushing up force of the back lid, so the parting board By supporting the step part of the body, it is possible to prevent the dial from deforming or breaking, and it is also possible to make the dial into a thin plate, which allows the overall display structure to be made thinner and has an excellent appearance. It has the effect that can be obtained.

Furthermore, the parting plate is formed by the dial, the cover glass, and the parting part of the parting plate, and can be provided in the gap where the hour hand and minute hand display parts are placed, so the overall display structure can be made thinner. have
