Problems solved by technology

[0007] And, in the timepiece with chronograph mechanism, generally the wheel that the chronograph shows is arranged at the final stage of the wheel train, therefore, in order to suppress the floating of the pointer, it is necessary to place the pointer seat or press it with a pressing spring, such pointer seat and pressing Increased load on the spring relative to the rotation of the gear train due to friction

Embodiment Construction

[0166] Next, a preferred embodiment of the present invention will be described based on a preferred embodiment shown in the drawings.

[0167] [Example]

[0168] A timepiece 2 equipped with a chronograph mechanism 1 according to a preferred embodiment of the present invention, that is, a timepiece 2 with a chronograph mechanism, for example, has approximately figure 2 Appearance shown.

[0169] That is, if figure 2 As shown, the timepiece 2 with a chronograph mechanism has an hour hand 11 and a minute hand 12, which rotate in a clockwise direction C1 around a central axis C, as chronograph hands, and the timepiece 2 with a chronograph mechanism also has: an hour chronograph hand 14 (e.g. for 12-hour accumulation, but can also be different), which rotates about central axis A; minute timer hand 15 (for example, for 30-minute accumulation, but can also be different), which rotates about central axis B; and second timer A needle 16 (eg for 60-second accumulation, but it can ...

Abstract

The invention relates to a timepiece with a chronograph mechanism, with no need of independent gear train of a chronograph. The timepiece (2) with the chronograph mechanism comprises a barrel wheel (25) and an acceleration gear train (4) which rotates along with the barrel wheel, speed of wheels at the tail end side of the acceleration gear train is regulated through a speed regulation escapement mechanism (30), and at least one gear train (51, 61) of the acceleration gear train is arranged as the chronograph gear which is kinematically connected to chronograph axes (54, 64) via clutch mechanisms (59, 69). The clutch mechanism is composed of vertical clutches which enables the chronograph axes to be actually connected with the chronograph gears in a vertical direction. The chronograph axes are integrated with clutch loops (55, 65), clutch springs (56, 66) and clutch spring supporting seats (57, 67), and the chronograph gears are integrated with clutch boards (51c, 61d).

Description

technical field [0001] The invention relates to a clock with a timer mechanism. Background technique [0002] In a clock with a chronograph mechanism, a wheel train for ordinary movement (hand movement) and a wheel train for timers are provided, typically: at the end of the wheel train for ordinary movement or at one end branched from the wheel train (Hereinafter, both are sometimes referred to as "the final stage of the gear train for ordinary hand movement") A chronograph gear train is added (for example, Patent Document 1). [0003] In such a timepiece with a chronograph mechanism, there is an advantage of being able to make the most of the existing gear trains for general movement of hands, but the support substrates such as the bottom plate and the bridge become complicated, and it is difficult to avoid gemstones (cavestones) and the like. The increase in bearing components. [0004] In addition, a timepiece with a timer mechanism intended to reduce the number of part...
