Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a switch device for buttoning an electronic watch, and more particularly to a switch device for buttoning an electronic watch having a plurality of contact functions.

Electronic watches powered by batteries, etc. must be configured to be able to adjust the time, such as hours, minutes, and seconds, or the day of the week, date, etc., in order to accurately display items such as the time. There is.

BACKGROUND ART Conventionally, in electronic watches that digitally display the time and the like using a display section such as a light emitting diode, a plurality of switches have been provided, and the time has been adjusted by operating the switches.

For example, if you want to adjust the seconds, simply operate the switch above to light the display and display the time, then pull the winding stem to stop the clock and display 00 seconds on the display. Reset the seconds counter in the clock circuit so that it is even on the radio.

Since the clock must be operated in accordance with the time signal broadcast on a television, etc., the switch operation is complicated and troublesome.

In addition, when a large number of switches are provided as described above,
In order to prevent accidental operation by fingers, clothing cuffs, etc. during normal use, the above-mentioned switch must be made difficult to operate, or a device must be installed to prevent erroneous operation, which complicates the structure of the watch. It has drawbacks.

The present invention eliminates the above-mentioned drawbacks and provides a switch in an electronic timepiece that allows multiple switch operations such as blinking the display of the timepiece and correcting the seconds to be performed easily and accurately by moving the winding stem. This is a proposal for a device.
The details will be explained below with reference to the illustrated embodiments.

The drawing shows one embodiment of a switch device in an electronic timepiece according to the present invention, and reference numeral 1 denotes a winding stem equipped with a crown 2.

The winding stem 1 is provided with a winding stem head 3 having a tapered tip, and the winding stem head 3 has a movable contact member whose one end is fixed to a pin 5 provided on a substrate 4. 6 is in contact.

The movable contact member 6 is made of a conductive elastic material, and includes a mounting portion 7 fixed to a pin 5 provided on the substrate 4, and a pair of spring portions 8 extending substantially parallel from the mounting portion 7. . It is composed of an extending contact portion 14.

The winding stem head 3 of the winding stem 1 is slid in relation to the pull-out or push-in operation of the crown 2, and is slid into the first groove portions 10, 11 or the second groove portion 12 of the movable contact member 6. .13, the contact portion 14 is moved via the spring portion 8 of the movable contact member 6.

Within the movable range of the contact portion 14 of the movable contact member 6, a pair of fixed contacts 15, 16 are provided at a predetermined interval.

In the switch device of the electronic watch configured as described above, when the crown 2 is not operated and is in the normal position, the winding stem head 3 of the winding stem 1 is moved to the first position of the movable contact member 6, as shown by the solid line in the drawing. It is interposed within the groove 10.11.

At this time, the movable contact member 6 is in a state where the spring parts 8 and 9 are slightly elastically deformed, and the contact part 14 is located between the fixed contacts 15 and 16. 15. A non-contact state with 16 is maintained.

When the crown 2 is pressed down in the above state, the winding stem 1 and the winding stem head 3 are moved as shown by the two-dot chain line in the drawing, and the winding stem head 3 moves the movable contact member. Push open the first groove part 10.11 of 6 and spring part 14.1.
5, the contact portion 14 is moved.

Therefore, the contact portion 14 of the movable contact member 6 is brought into contact with one of the fixed contacts 15 as shown by the two-dot chain line.

If you keep your hands still on the crown 2 and press the crown 2 into the 11th position, - the spring portion 8 of the movable contact member 6,
Since the winding stem head 3 is pushed back by the elasticity of the winding stem 9, the winding stem 1 having the winding stem head 3 is returned to the position shown by the solid line.

Next, when the crown 2 is pulled out and operated 7, the winding stem head 3 moves into the second groove 12.1 of the movable contact member 6, as shown by the dotted line.
Move to interpose 3.

In connection with this, the movable contact member 6 moves as shown by the dotted line due to the elasticity of the spring parts 8 and 9, and the contact part 14 comes into contact with the fixed contact 16.

When the crown 2 is pushed in again to return the winding stem head 3 to the normal position shown by the solid line, the movable contact member 6 moves to the spring parts 8 and 9.
The contact part 14 returns to the intermediate position of the fixed contact 15, 16.

In the switch device configured in this manner, for example, when the crown 2 is pushed in and the contact portion 14 of the movable contact member 6 and the fixed contact 15 come into contact, the display portion of the clock lights up to display the time, etc. On the other hand, when the crown 2 is pulled out and the contact portion 14 of the movable contact member 6 and the fixed contact 16 come into contact, the operation of the watch is stopped and a second counter (both not shown) inside the watch circuit is reset. It can be used by an appropriate person, such as adjusting the seconds using the crown 2, and a plurality of switch operations can be performed by simply moving the winding stem 1 via the crown 2.

Although the present invention has been described in detail based on the illustrated embodiments, the present invention is not limited to the illustrated embodiments. For example, in the drawings, the movable contact member 6 has a pair of spring parts 8 and However, it is also possible to remove one of the spring parts 9.

In addition, the shape of the contact part extending from the spring part of the movable contact member,
Various modifications can be made, such as a two-pronged tuning fork shape, and a pair of fixed contacts can be provided inside the three-pronged contact part.
Improvements can be made.

As described above, the switch device in the electronic timepiece according to the present invention is provided with a movable contact member having a contact part that is moved in association with the movement of the winding stem, and fixed in the movable range of the contact part of the movable contact member. Since the structure is such that a contact is provided and the switch is operated by bringing the contact portion into contact with a fixed contact according to each movement position of the winding stem, multiple switch operations can be performed easily and reliably with one switch. It is possible to fully achieve the intended purpose, such as eliminating the need to provide a large number of switches inside the watch as in the past, and making the watch more compact. It is.
