7 is a battery-powered quartz watch movement,
8 is a move pedestal. The movement 7 is fixed to the move receiving base 8 in advance, and is stored while being prevented from rotating with respect to the recess 2a of the case 2. Reference numeral 9 is a general pointer shaft having a double-axis structure perpendicular to the movement 7, and 10 is another pointer shaft arranged in a direction perpendicular to the pointer shaft 9,
It is fixed to the move pedestal 8.

As shown in FIGS. 2 and 4, reference numeral 11 is an hour hand formed from a thin plate of aluminum or the like in a substantially umbrella shape. The flat top plate 11a of the hour hand 11 is provided with a central hole 11b, and the side surface 11c has a substantially spherical shape that is sliced. The position of the hem of the side surface 11c coincides with the center position of the pointer shaft 9, as also shown in FIG. Therefore, the hour hand 11 overlaps with a part of the pointer fixed to the pointer shaft 9 in the direction of the pointer shaft 9. An hour wheel 12 is fixed to the central hole 11b of the hour hand 11, and a tooth profile (not shown) that meshes with the intermediate train wheel is formed on the lower surface of the hour wheel 12. The hour hand 11
It is rotatably supported by another pointer shaft 10 and driven from a needle wheel train (not shown) via an intermediate train. For example, as shown in FIG. 3, numbers or patterns for displaying the time are printed on the side surface 11c near the hem.

As shown in FIGS. 2 and 5, reference numeral 13 is a substantially umbrella-shaped minute hand made of a thin aluminum plate or the like. A flat top plate 13a is formed at a slightly depressed position in the central portion, and a central hole 13b is opened. 14 is a central hole 13b

As shown in FIGS. 2 and 6, reference numeral 15 is a disk-shaped second hand made of a thin aluminum plate or the like. Reference numeral 16 denotes a boss portion for fixing the second hand 15 to the pointer shaft 9, which is fixed to the central hole 15b. For example, as shown in FIG. 3, numbers, patterns, etc. are printed on the surface of the second hand 15. Generally, since the display area of the second hand 15 is small, simple scales and marks (large and small circles here) are mainly used. In addition, each pointer made of aluminum is given at least one of alumite treatment, thin film coating of metal by dry plating method, coating of paint by painting, and coating of ink by printing to give corrosion resistance and decorativeness. Has been done.

Next, the operation of the first embodiment will be described. The time display surfaces of the minute hand 13 and the second hand 15 rotate clockwise on substantially the same spherical surface, and a part thereof can be visually recognized through the windshield 3 from the display window 2b. The time display surface of the hour hand 11 rotates slightly outside the time display surface of the minute hand 13 and the second hand 15 from right to left (clockwise when viewed from above). On the windshield 3, "hour" is displayed on the upper half, "minute" is displayed on the lower half, and "second" is displayed on the lower center half. FIG. 1 displays the time of exactly 12:00.

When the case 2 is held such that the hanging string of the pendant is struck with one hand and the lower can 4 is oriented downward, the time display is displayed on the case 2 so that the time display can be read in the correct posture. The letters and patterns of the parts may be arranged upside down.

Next, the effect of the first embodiment will be described. Since the hour hand 11, the minute hand 13, and the second hand 15 both have a substantially spherical surface in conformity with the substantially spherical case 2, the interval between the time display surface and the case 2 becomes substantially constant,
The display is easy to see from any direction through the windshield 3 having a substantially spherical shape. It was suitable for the long and narrow display window 2b provided in the substantially spherical case 2, and the interesting three-dimensional time display with hours, minutes, and seconds was made.

Next, the configuration of the second embodiment of the present invention will be described. FIG. 7 is a front view showing the structure of the time display portion of the wrist watch according to the second embodiment of the present invention, and FIG. 8 is a partially transparent side view of the wrist watch.

In FIGS. 7 and 8, 21 is a wrist watch. 22 is a metal case of the wristwatch 21. Reference numeral 23 denotes a glass windshield having a substantially cylindrical surface shape, which is fixed to the display window 22a at the center of the surface of the case 22. A part of the lower surface of the glass of the windshield 23 is covered by printing or metal deposition. Reference numeral 24 is a dial on which a minute / second scale or numbers are printed. 27 is a movement of a quartz watch. Reference numeral 29 is a pointer shaft having a double shaft structure, 33 is a bar-shaped minute hand fixed to the outside of the pointer shaft 29, and 35 is a bar-shaped second hand fixed to the pointer shaft 29.

Reference numeral 30 denotes another pointer shaft, which is one of the features of the present invention, and is arranged at a right angle to the pointer shaft 29.
Reference numeral 31 is an hour hand formed in a substantially drum shape and pivotally supported by another pointer shaft 30. The hour hand 31 is arranged at a position apart from the minute / second display surface so as not to cover the display surface. Therefore, the hour hand 31 does not overlap the minute hand 33 and the second hand 35 in the direction of the pointer shaft 29. The hour hand 31 is provided with a number or a pattern representing the hour character, and the time display surface is shown in FIG.
Then it moves from bottom to top. Reference numeral 25 is a decorative jewel set in positions corresponding to, for example, 12 o'clock and 6 o'clock. The time of this clock is displayed as 12:30:11.

Next, the effect of the second embodiment of the present invention will be described. Since the hour hand 31 has a substantially drum shape,
Combining with the bar-shaped minute hand 33 and second hand 35, the time display was more interesting than ever. Further, since the hour hand 31 is arranged at a position where it does not overlap the minute hand 33 and the second hand 35 in the direction of the pointer shaft 29, the drum diameter can be made small. Further, by this, the time display of "hour", "minute", and "second" can be arranged on substantially the same plane, and the thickness of the entire timepiece can be prevented from becoming excessive.

Since the time display of the present invention is not limited to the above-described embodiment, other embodiments will be described. For example, the rotation direction of each pointer and the other pointers can be designed in the opposite direction to the above description. Further, the angle formed by both pointer axes can be designed by selecting an arbitrary angle other than a right angle. Also,
Instead of the hour hand, the other hands may be provided with a minute hand. In this case, the hour hand is fixed to the same pointer shaft as the second hand. Of course, it is possible to omit any one of the hands, for example, the second hand. Therefore, at least one of the hour hand, the minute hand and the second hand is fixed to the pointer shaft. Regarding the shape of each fixed pointer, the other pointers have a substantially umbrella shape, a substantially drum shape or a substantially disc shape, and the pointers have a substantially umbrella shape, a substantially rod shape, or a substantially flat plate shape. , Etc. can be arbitrarily selected. It is also optional to fix the ornamental jewelry to any pointer.

It is needless to say that the numbers and patterns printed on the hour hand, the minute hand and the second hand can be arbitrarily selected and used in any combination. For example, there are Roman numerals and Arabic numerals in the numbers, and in the pattern, as shown in FIG.
A pattern in which the time is displayed by changing the pattern, or FIG.
Various patterns are conceivable, such as the pattern shown in (b) in which the time is displayed by a change in the number of patterns or the pattern shown in FIG. 9 (c) in which both elements are mixed. Further, in each of the above-described embodiments, aluminum is used as a material for each pointer, but it goes without saying that a copper alloy such as brass, a noble metal such as gold alloy or platinum, a plastic, or the like can also be used.

[0029]

As described above, according to the present invention,
In the pointer display type timepiece, in addition to the pointer shaft for fixing the pointer, another pointer shaft inclined with respect to the pointer shaft is provided, and another pointer is fixed to the other pointer shaft. Since the other hands and the above hands are combined to display the time, a new 3
We were able to provide an interesting time display part in a dimension.

The pointer fixed to the pointer shaft is at least one of an hour hand, a minute hand, and a second hand, and the other pointer is selected to be an hour hand or a minute hand. The shape is appropriately selected from a substantially umbrella shape, a substantially flat plate shape, and a substantially rod shape so as to be fixed to another pointer shaft. Since at least one of them is provided, the time display which is rich in design can be made by combining these.
