Description

[Detailed description of the invention] The present invention relates to a striking clock.

Conventionally, in this type of striking clock, in order to switch between various functions, such as stopping the striking sound, single striking, setting the time, and repeated striking, it is necessary to operate multiple operating axes, which is not easy to use. However, the configuration was complicated and the cost was high. It is an object of the present invention to eliminate the above-mentioned drawbacks and provide a timepiece with a simple structure and ease of use.

The hourly clock of the present invention will be explained below with reference to the drawings.

In Figures 1 to 6, 1 is a watch case;
A timepiece movement mechanism 2 is housed inside, and a switch body 4 connected to the timepiece movement mechanism 2 via a flat cable 3 and a speaker 5 connected to the switch body 4 are also provided. Further, the switch body 4 includes a printed board 7 fixed to the housing 6, and a conductor is printed on the printed board 7 in a predetermined pattern. 8 is a semi-fixed variable resistor in which the terminal 9 is inserted into the hole 10 of the printed board 7 and fixed by soldering, and the volume control shaft 11 is passed through and fixed.
The volume operation shaft 11 itself is pivotally supported by the housing 6 and the printed board 7, and projects outward from the housing 6.
By rotating the semi-fixed variable resistor 8, the resistance value of the semi-fixed variable resistor 8 can be changed.

Reference numeral 12 denotes a switching operation shaft, which has a hollow cylindrical tip 13 with an open end, is pivotally supported by the housing 6 and the printed board 7, and projects outward from the housing 6. Grooves 14, 14 are formed in the tip portion 13, the width of which is larger on the inner side than on the tip side, and extends in the longitudinal direction, and can be inserted into the notches 16, 16 of the through hole 15 of the printed board 7. Protrusion 1
7 and 17 are provided protrudingly. Reference numeral 18 denotes a contact block which is arranged parallel to the switching operation shaft 12 with a compression spring 19 interposed therebetween, and has a hole 20 through which the tip end 13 is inserted. Further, around the hole 20, a pair of protruding edges 21,
21 are provided opposite to each other, and a recess 2 engages with the protrusions 17, 17 of the tip portion 13 in a part of the hole 20.
2, 22 are formed. Reference numeral 23 denotes a contact spring having a window 24 that matches the pair of projecting edges 21, 21, and into which pins 25, 25 protruding from the contact base 18 are engaged and fixed to the contact base 18; Contact arms 26, 26 capable of contacting the conductor of the printed board 7
are set up opposite each other. 27 is a compression spring that can be accommodated in the tip 13 of the switching operation shaft 12;
The push button contact inserted into the groove 4 is inserted into the widest part of the grooves 14, and is fixed. 29
is a click spring whose both ends are engaged with and held by holding parts 30, 30 provided inside the housing 6, and a locking part 31 bent in a V-shape at the center is connected to the contact block 18. It is provided so that it can be engaged with the recess 32 of the contact base 18, and is provided so that a click motion is applied when the contact base 18 rotates.

Reference numeral 30a denotes a mounting boss, and after the printed board 7 is attached to the housing 6, the printed board 7 can be fixed by screwing in the screw 33. Reference numerals 34 and 35 designate knobs connected to the projecting ends of the volume control shaft 11 and the switching control shaft 12 from the housing 6, respectively.

Further, the operation of the present invention will be explained in detail. Now, if the knob 35 integrated with the switching operation shaft 12 is rotated, the protrusions 17, 17 of the switching operation shaft 12 and the recesses 22, 22 of the contact block 18 are engaged, so that the contact block 18 is also integrated. As the contact spring 23 is rotated, the contact arms 26, 26 of the contact spring 23 attached to the contact base 18 are brought into contact with the conductor printed in a predetermined pattern on the printed board 7, thereby switching the circuit. Next, by rotating the switching operation shaft 12, the protrusion 1
7 and 17 are notches 1 of the through holes 15 of the printed board 7
6 and 16, the click spring makes it easy to check whether or not there is a match, and the switching operation shaft 12 is connected to the printed board 7.
When pushed in, the tip 13 of the switching operation shaft 12
A push-button contact 28 mounted on the printed circuit board 7 is brought into contact with the printed circuit board 7 and can, for example, short-circuit the conductor parts 36, 36.
In this case, the contact base 18 is maintained in a stationary state because its projecting edges 21, 21 abut against the printed circuit board 7.
Therefore, if the conductor of the printed circuit board 7 is provided to suitably connect to a circuit that performs a desired function such as stopping the hour-beating sound, single-beating, hour-beating, time setting, and repeated striking,
Various operations can be performed with one operating axis. In other words, by equipping a single operation shaft with a contact body that contacts the printed circuit board 7 in a rotational motion and a contact body that contacts the printed circuit board 7 in a pushing motion, switching of various operations can be performed with a single operation shaft. This can be achieved through the operating axis. Furthermore, if a volume control shaft 11 for operating a variable resistor is provided, the volume can also be adjusted freely.

According to the hourly clock of the present invention configured as described above, it is easy to use and has a simple configuration.
Achieve remarkable effects such as lowering costs.
