DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a timepiece characterized by a method for indicating elapsed time.

[0002]

2. Description of the Related Art Generally, a timepiece has hands such as a long hand and a short hand on a dial having a scale on a surface thereof, and the time and elapsed time are grasped by reading the scale indicated by the hands.

[0003]

However, in the above-mentioned timepiece, although the time can be empirically recognized by the angle between the long hand and the short hand, the idea of geometrically grasping the passage of time is not. It was thin.

[0004] Therefore, an object of the present invention is to provide a clock capable of geometrically recognizing the passage of time.

[0005]

In order to solve the above-mentioned problems, the present invention provides a pointer which rotates at a constant angular velocity on a base located in a case, and has a contour of a regular polygon, The indicator and the center coincide with the surface of the base
Then, a figure having the same contour was drawn.

[0006]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a timepiece according to the present invention will be described below with reference to the accompanying drawings.

As shown in FIGS. 1 and 2, an indicator 2 is provided on a base 1 located in a case C. The indicator 2 includes an outer peripheral member 3 having a regular triangular outline, and a connecting member 4 that connects the outer peripheral member 3 and the rotating shaft 5, and rotates at a constant angular velocity with the rotation of the rotating shaft 5.

[0008] The outer peripheral member 3 and the center
And the figure 6 having the same contour is drawn.

The rotation cycle of the indicator 2 is
The operation can be switched to 3 hours, 6 hours or 12 hours.

In the above timepiece, as time elapses, the figure 6
Is changed, for example, when the rotation cycle of the pointer 2 is 3 hours, the phase of the outer peripheral member 3 coincides with the contour of the figure 6 once an hour (see FIG. 3). .

As described above, by reading the change in the phase of the pointer 2 with respect to the figure 6, it is possible to intuitively recognize the passage of time. The position of the connecting member 4 also serves as a clue for time recognition.

The contour of the outer peripheral member 3 may be a polygon other than an equilateral triangle. In this case, if the rotation cycle of the indicator 2 is set to be an integral multiple of the angle, the time can be easily grasped.

In addition, as shown in FIGS. 4 and 5, projecting pieces 8 are provided at each corner of the indicator 2 and the projecting pieces 8 are
The indicator 2 can be prevented from dropping from the rotating shaft 5 by an impact by engaging with the groove 9 formed on the inner peripheral surface of the rotary shaft 5.

[0014]

As described above, in the timepiece according to the present invention, it is possible to intuitively recognize the passage of time by reading the phase change of the pointer with respect to the figure drawn on the base, so The sensibility is cultivated.

[0015] In addition, the design is unprecedented and unusual.
