RU1770946C - Quartz clocks with side second hand - Google Patents

Abstract

Usage: the invention relates to time devices and can be used to unify clock mechanisms. SUMMARY OF THE INVENTION: Expanding the functionality of quartz watch mechanisms by introducing an additional kinematic pair, allowing the clock to be executed with a second hand. When the stepper motor is rotated by the strobes Zi, the rotation is transmitted to the axis of the first intermediate wheel with wheels Z2-Z3, equipped with a tribs Za, which transmits rotation to the gear wheel Z4, mounted on an axis equipped with a second hand and placed offset from the central o-cm mechanism. 1 ill.

Description

The invention relates to time devices and can be used in the watch industry.

A watch is known comprising the minute and hour hands, as well as the first second, minute and hour hands for the stopwatch. A large number of scales in the given analogue makes it difficult to read the necessary information.

Currently, domestic watch factories, for example, manufacture men's watches with a central second hand. In these cases, the movement from the stepper motor through the tribes is transmitted to the axis of the intermediate wheel, then to the axis of the central second hand, and then to the clock axis. The disadvantage of this analogue is the traditional arrangement of the second hand on the central axis, which does not meet the requirements of the market today.

There are known electronic watches with a stepper motor, selected as a prototype, in which an embodiment with a side second hand is provided. This watch contains a stepper motor and a simple wheel system, KOTOpcf allows selection of the rotation speed to obtain a version that allows the second axis to rotate at a speed of one revolution per minute and a dial with a side second hand, but in this version the kinematic scheme of the mechanism differs from the proposed solution. In addition, the prototype mechanism is designed for large watches, as dimensions of the stepper motor are large enough

The purpose of the invention is to enhance functionality.

The essence of the proposed solution lies in the fact that an additional pair of koleo-tribes and a gear wheel with an axis are introduced into the clock mechanism. Moreover, three is located on the axis of the first intermediate wheel and is kinematically connected to the s / cog wheel, which is fixed at oci / seconds

bottom of the arrow. The second hand is placed with an offset relative to the central axis with the arrows.

The kinematic diagram of a quartz watch with a lateral second hand shows the essence of the proposed device, which consists of a stepper motor ДС, interconnected with the tribe Zn of the 1st intermediate axis, on which the wheel Z2, the tribes Zs, the wheel Z3, the central axis are located, which are the tribes Zs wheel ZA, the minute axis with the wheel ZB and the tribe Zg located on it, the clock axis, on which the wheel Zi2 of the 2nd intermediate axis is mounted with the wheel Ze, tribe Zy, wheel Zio and tribe Zn, axis of a second second hand with a wheel

Zi4.

The tribes and wheels are interconnected as follows: Zi-Zz; Zs-Ze; Zy-Zs; Zg-Zio; Zii-Zia; Zi3-Zi4. The distance from the center of the clock to the axis of the side second hand is 5. .1 mm at m 13-14 0.07923 mm,

The watch works as follows.

Movement from the stepper motor (LH) is transmitted through the Zi tribe to the axis of the intermediate wheel Z2-Zs, then to the axis of the central second hand ZA and through the wheels Zs-Ze-Zy-Zs to the minute hand axis, and through the wheels Zg-Zio Zi i-Zi2 on the hour axis, on the side second hand, the movement from the axis of the first intermediate wheel is transmitted through the wheels.

A positive effect of the use of the proposed watches is that the shift of the second hand relative to the central axis allows the creation of new watches both in design and in appearance, and in their functionality.
