Abstract

The utility model relates to a moon display device for a clock, which is in the mode of single month and realizes a moon display function, having the characteristics that after a lunar month of a moon plate turns 360 DEG, the moon plate is provided with a window and a static component is printed with patterns, when the window and the patterns have a relative movement, the patterns observed from the window can simulate the changes of the moon. The device has the characteristics of simple manufacturing process and original appearance, and the utility model is regarded as a new moon device on clocks and watches.

Description

Month display device for clock

The utility model relates to a kind of device of realizing phases of the moon Presentation Function on clock and watch.

The phases of the moon Presentation Function of clock and watch turned over 360 ° moon dial and had relative motion between quiet (as the card) of folding fan-shaped window by being printed on two full moon patterns, about two lunations in the past, and the circle that shows the moon in quiet folding fan-shaped window lacks and changes.The phases of the moon tooth number that this structure drives moon dial is generally 59 or 60, and tooth pitch is little, to the susceptibility height of error, to the requirement on machining accuracy height of part, cause the cost height.

The purpose of this utility model is to provide the about lunation of a kind of moon dial to turn over 360 ° odd month type phases of the moon device, and it can reduce the difficulty of processing of phases of the moon device effectively, reduces cost.

The purpose of this utility model is achieved in that the phases of the moon takes turns an about lunation and turn over 360 °, moon dial and the interlock of phases of the moon wheel.On one quiet and moon dial, one be printed on pattern, another has and the corresponding window of pattern form, axially go up window and be positioned on the pattern.When window and pattern have relative motion, from window, see the pattern of moon shape.In phases of the moon wheel turned over 360 ° process, the pattern in the window was simulated the change procedure of the moon in a lunation by " the first day of the lunar month " to " prestige ", gradually changed by " prestige " to " the first day of the lunar month " again.

The utility model since the phases of the moon take turns an about lunation and turn over 360 °, phases of the moon wheel can be made 29 or 30 teeth, the pitch of comparing these phases of the moon gear teeth on same circumference with the phases of the moon wheel of 59 or 60 teeth is big, reduced its susceptibility to error, thereby can reduce the requirement on machining accuracy of other part, improved process efficiency and qualification rate, reduced cost, its outward appearance is also relatively more novel simultaneously.

The concrete structure of utility model is provided by following examples and accompanying drawing thereof.

Fig. 1 and Fig. 2 are respectively the clock and watch that the utility model proposes sectional view and the planimetric maps with odd month type phases of the moon device.

Below in conjunction with Fig. 1 and Fig. 2 the concrete device that the utility model proposes is described in further detail.

The phases of the moon wheel (3) of this device is contained in the rotating shaft of movement (4), and it has 29 or 30 teeth, approximates the fate of a lunation.Moon dial (2) and phases of the moon wheel (3) are fixed together, and an about lunation turns over 360 °.Be printed on the pattern (10) of a full moon shape on the moon dial (2), the shape of corresponding pattern (10) moves in window (9) having window (9), pattern (10) on quiet (1), axially goes up window (9) and is positioned on the pattern (10).The inner curve (8) of window (9) covers the different area of pattern (10) at pattern (10) when being in diverse location, make the pattern that exposes in window (9) be moon shape, and in pattern (10) turned over 360 ° process, moon shape was by " the first day of the lunar month " to " prestige ", gradually changed by " prestige " to " the first day of the lunar month " again.The external curve (7) of window (9) does not play the covering effect to pattern (10).Two other curve (5) and (6) of forming window (9) are the transition arcs of the design for the complete of quiet (1).Be imprinted on the moon dial (2) as the shape with window (9), open the window of a pattern (10) shape on quiet (1), when moon dial (2) rotated, the circle that the moon shape of seeing in the window also can be simulated the moon lacked variation.

Claims

1, a kind of clock and watch odd month type phases of the moon device, be characterised in that the moon dial (2) and phases of the moon wheel (3) interlock, an about lunation turns over 360 °, have window (9), one and be printed on pattern (10) last one of quiet (1) and moon dial (2), at window (9) and pattern (10) when relative motion is arranged, lack by the circle of pattern (10) the simulation moon of seeing in the window (9) and to change.

2, device according to claim 1, the shape that it is characterized in that window (9) is corresponding with the shape of pattern (10), make the pattern of seeing in the window (9) (10) be moon shape, in pattern (10) turned over 360 ° process, the moon shape in the window (9) was by " the first day of the lunar month " to " prestige ", gradually changed by " prestige " to " the first day of the lunar month " again.

3, device according to claim 1 is characterized in that window (9) is positioned on the pattern (10).
