Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a disc structure of a disc display timepiece that displays the time by rotating the disc.

[Conventional technology]

As a conventional technique, as shown in the cross-sectional view of the main part of the watch in FIG. 2 and the plan view of the watch in FIG.
A medium-diameter minute indicator plate 32 and a small-diameter seconds indicator plate 31 are installed in layers on the central axis of the watch, and time indicator points 42a, 41a, and 40a are displayed on the upper surface of the outer periphery of each disk, while the glass 38 is provided with a plurality of dividing lines 39 for reading the time, and further includes stair component members 35, 36, and 37 having a plurality of steps having different design elements from the indicator board on the outside of each disc-shaped indicator board. I'm letting you do it.

In addition to the above, there are also devices in which a dividing line is provided on a fixed exterior member other than glass. Further, in the figure, 34 is a dial plate, which closes the gap between each staircase component and each indicator plate.

[Problem that the invention seeks to solve]

In the prior art, the indicator boards that display the time are disc-shaped, and the outer periphery of each disc is downwardly slanted.In this structure, the central axis of the indicator board that fixes each indicator board is Because it is difficult to increase the outer diameter of each indicator board due to problems such as misalignment, horizontal play in the center axis, and scratches caused by vertical deflection of each indicator board, the display on each indicator board is restricted in terms of design. Ru. Furthermore, since the outer diameter of the indicator plate cannot be increased, men's watches with relatively large display sections require other components such as staircase components in addition to the time display plate due to design considerations.

Furthermore, since the indicator boards were stacked in three stages, the difference in level between each indicator board was clearly visible when viewed from the top of the watch, which was a common design and lacked interest. The present invention solves these problems and provides a new disc structure that eliminates the need for stair component members, prevents scuffing between the discs even when the diameter of the disc is increased, and allows for greater design variation. The purpose is to

The second rising step 24 is formed at the outer edge of the dividing plate 2 with a gap 11 and is continuous with the time display surface 1a, and the first rising step 23 of the hour plate 1 is The dividing plate 2 is formed with a gap outward from the first rising step 20, and the size of the gaps 15, 16, 17 between the dividing plate 2 and the time plate 1 in the rotation axis direction is , gap 15< gap 16< gap 17.

〔Example〕

Embodiments of the present invention will be described below based on the drawings. FIG. 1 is a sectional view of a main part of a time display section according to a first embodiment of the present invention.

In FIG. 1 showing the time display part of the hands according to the first embodiment, 1 is the hour plate, 2 is the division plate, 3 is the seconds plate, 1a,
2a and 3a are the respective time display surfaces, 4 is the hour wheel, 5 is the division pinion, 6 is the seconds wheel, 7 is the hour wheel pusher, 8 is the glass, 9 is the side body, 10 is the seconds wheel and minutes. The gap between the boards,
11 is the gap between the dividing plate and the time plate, 12, 13, 1
4, 15, 16, 17 are the gaps in the vertical direction, 2
0 and 22 are a first rising step and a second rising step of the dividing plate, 21 is a facing surface, and 23 and 24 are a first rising step and a second rising step of the time plate.

The flat plate-shaped second plate 3 is fixed to the second plate shaft 6, and its top surface is the same plane, and the top surface of its outer periphery is a time display surface 3a.After finishing, the top surface is printed with various time display points, time display arrows, etc. is marked. Below the seconds plate 3, there are arranged a dividing plate 2 and an hour plate 1 whose centers are respectively fixed to the dividing pinion pinion 5 and the hour plate wheel 4. The dividing plate 2 has a first portion extending from the center of rotation toward the outer circumference.
rising step portion 20 and second rising step portion 2
2, the second rising step portion 22 is formed at the outer edge of the seconds plate 3 with a gap 10, and is connected to the time display surface 2a. In addition, the time plate 1
is provided with a first rising step 23 and a second rising step 24 from the center of rotation toward the outer periphery, and the second rising step 24 is formed with a gap 11 at the outer edge of the dividing plate 2. time display screen 1a
The first rising step 23 of the hour plate 1 is connected to the first rising step 2 of the dividing plate 2.
It is formed with a gap outward from 0. The time display surfaces 2a and 1a of the dividing plate 2 and the hour plate 1
Various indications such as a time display point for time display, a time display arrow, etc. are marked by printing or the like. The time display surfaces 2a and 1a of the partition plate 2 and the hour plate 1 are located on the same plane as the seconds plate 3, and there is no difference in level even when viewed from the top of the watch. 1
1 can be made very small, so that the disk below the gaps 10 and 11 is almost invisible.

The outer diameter of each disk is the size of seconds plate < division plate < hour plate, and since the outermost periphery of the hour plate is close to the facing surface 21 of the side barrel 9, the characters shown in FIGS. 2 and 3 There is also the advantage that the board and each staircase component are unnecessary, and the cost is reduced accordingly.

In this way, the outer diameters of the second plate 3, division plate 2, and hour plate 1 can be made much larger compared to the conventional structure.
Moreover, since the display surfaces of each disk are on the same plane,
The time display specifications for each disc allow for a wider range of design specifications than ever before. Also, regarding the scratches between each disc due to deflection etc. due to increasing the diameter of the disc, use the large diameter division plate 2 and time plate 1.
From the center direction to the outer circumferential direction, the amount of clearance is 1
The relationship 5<16<17 and 12<13<14 is used to prevent scratches between the discs. In this embodiment, although marks such as time display dots are displayed on the time display surface, the time is displayed without dividing lines, etc. However, in order to make the time display even easier to see, the time display is printed or printed on the bottom or top of the glass. The sections may be provided by techniques such as vapor deposition.

[Effect of idea]

As is clear from the above explanation, according to the present invention,
Even if the diameter of the disk is increased, the structure is such that scratches due to vertical movement between the disks are difficult to occur, so it is possible to display the time accurately, and a disk display clock using an unprecedentedly large disk can be used. It became possible. In addition, it became possible to increase the diameter of the discs, and by arranging the time display surfaces of each disc on the same plane, the design was streamlined, and design variations were expanded, creating new A type of disc display clock can be made. Also, since dial plates, stairway components, etc. are not required, there is a great effect in terms of cost merit.
