Problems solved by technology

For traditional clocks and watches, whether the dial is round, oval or square, the numbers indicating the time are distributed along the circumference; the hour and minute hands are straight lines, and the length of the straight line is used to distinguish hours and minutes. The expression form is relatively simple. The numbers distributed along the circumference cannot be well adapted to non-circular dials, which also limits the design expression of various dials with special shapes.

Embodiment 1

[0038] Such as Figure 1-4 As shown, a clock with a curved pointer includes a dial 70 and a time scale and a pointer arranged on the dial. The pointer rotates around one end of the dial, that is, the rotation point O point parallel to the plane of the dial 70. The pointer is equal to Speed ​​spiral, the time scale is arranged in a straight line, and the center position of the straight line segment of the time scale arrangement intersects with the rotation end O point of the pointer, that is, the time scale is divided into two parts and symmetrically distributed on both sides of the pointer rotation end O.

[0039] In this example, if image 3 As shown, the curved pointer is the hour hand 51, and the curve is a setting segment on the Archimedes spiral. The clock also includes a minute hand 61, and the minute hand 61 adopts a straight pointer and a scale distributed on a circle as an indication method, wherein the hour hand The speed ratio of 51 and minute hand 61 is 1:12.

[...

Embodiment 2

[0057] A timepiece with curved hands, which has the hour hand 51 and the corresponding hour hand scale 52 as described in Embodiment 1, the difference is that the minute hand 61 of the timepiece is also set as a constant velocity spiral.

[0058] Such as Figure 5 As shown, the pointer includes an hour hand 51 and a minute hand 61, the rotating ends of the hour hand 51 and the minute hand 61 coincide at point O, and the corresponding hour hand scale 52 and minute hand scale 62 are vertically intersected on the dial 70, and the minute hand scale is in the middle of 0-60 The interval is an integer of 5, and the distribution mode is 52 at the same time, and the rotation speed ratio of the hour hand 51 and the minute hand 61 is 1:12.

Embodiment 3

[0060] Such as Figure 6 As shown, a clock with curved hands has the hour hand 51 and the minute hand 61 and the corresponding time scale as described in Embodiment 1, the difference is that it also has a second hand 63, and the second hand 63 of the clock is based on the existing The method in the technology is set as a straight pointer and corresponding scales distributed around the circumference, the minute hand 61 and the second hand 63 can be arranged on the same small dial 71, and the rotation speed ratio of the hour hand 51 and the second hand 63 is 1:720.

Abstract

The invention belongs to the technical field of clocks, and particularly relates to a clock with curvilinear pointers. The clock comprises a dial plate, time scales and pointers; the time scales and the pointers are arranged on the dial plate; each pointer rotates around one end, namely a rotating end, of the pointer and is parallel to the plane of the dial plate, the pointers are constant-speed spiral lines, the time scales are arranged in a straight line, and connecting lines of the time scales are intersected with the rotating ends of the pointers. According to the clock, a hour pointer and a minute pointer adopt curves, numbers representing time are distributed along a straight line, the problem that numbers representing time in a traditional clock needs to be distributed along the circumferential direction of the pointers and cannot be well matched with a non-circular dial plate is solved, the curvilinear-form dial plate can be matched with a dial plate of a special shape, and the application range is wider.

Description

technical field [0001] The invention belongs to the technical field of clocks and watches, in particular to a clock with curved hands. Background technique [0002] Clocks are widely used in various fields and different groups of people. For traditional clocks and watches, whether the dial is round, oval or square, the numbers indicating the time are distributed along the circumference; the hour and minute hands are straight lines, and the length of the straight line is used to distinguish hours and minutes. The expression form is relatively simple. The numbers distributed along the circumference cannot be well adapted to non-circular dials, which also limits the design expression of various dials with special shapes. Contents of the invention [0003] In order to solve the above-mentioned technical problems, the present invention utilizes the constant velocity characteristic of the Archimedes spiral to provide a dial with a curved pointer, the hour hand and / or minute han...
