Description

[Detailed explanation of the idea] (Industrial application field) The present invention relates to an alarm clock.

(Prior Art) There have been various types of alarm clocks that emit alarm sounds using phosphorus. In this case, the stop button is often provided on the back of the watch, and whether the alarm is set or stopped is determined by the position of the stop button on the back of the watch.

(Problems to be solved by the invention) In the conventional technology as described above, it is difficult to determine whether the sound stop button is in the set state or the sound stop state based on the slight difference in the position of the sound stop button. It was not uncommon for me to forget whether the sound was turned off or not, which was really inconvenient in daily use.

An object of the present invention is to provide an alarm clock that allows you to see at a glance whether it is in a set state or a non-ringing state, and in which it is easy to turn off the alarm clock.

(Means for Solving the Problems) The present invention is characterized by a ring disposed on the top surface of the watch case, and a bell striking member provided close to the ring so that the ring can be struck. , a driving means for the bell striking member, and a ringing stop button provided above the ring so as to be movable in the vertical direction so as to cover the ring;
It consists of a ring stop switch installed inside the watch case that opens and closes in conjunction with the displacement of the ring stop button, and the ring is visible from the outside when the ring stop button is moved to the upper position. It's in a certain place.

(Example) In FIG. 1, the watch case 1 includes a front frame portion 11,
It consists of a rear frame part 12, an upper frame part 13 and a bottom frame part 14. A pipe 15 projects upward from the upper frame part 13, and a bowl-shaped phosphor 2 is fixed to its tip. The outer peripheral surface of the phosphor 2 is painted in a bright and conspicuous color, for example, red. A bowl-shaped stop button 3 is positioned so as to cover the ring 2, and a guide shaft 31 projects inward from the inner surface of the stop button. The guide shaft 31 penetrates the cylindrical body 15 and projects into the inside of the watch case 1, and the escape prevention member 4 is attached to the projecting end. The planar shape of the ring stop button 3 substantially matches the planar shape of the watch case 1. The ring stop button 3 is vertically displaceable above the ring 2, so that the guide shaft 31 protrudes into the watch case 1 by at least its stroke when in the ring stop state. The inner circumferential surface of the cylinder body 15 is formed into two stages, a large diameter part and a small diameter part, in the upper and lower axial directions, and the return spring 5 is fitted into the large diameter part to urge the noise stop button 3 upward. are doing. A switch pressing piece 32 is formed to protrude from the inner surface of the ring stop button 3 toward the inside of the watch case 1. A printed circuit board 6a is disposed within the watch case 1 at a position facing the switch pressing piece 32, and a contact piece 6b is fixed to this printed circuit board at one end to form the stop switch 6. ing. The stop switch 6 is opened and closed in conjunction with the vertical displacement of the switch pressing piece 32 together with the stop button 3.

A bell-striking member 7 is provided on the upper surface of the upper frame portion 13 in close proximity to the ring 2, and a drive motor 8 serving as a driving means for the bell-striking member 7 is housed in the watch case 1. In the example, the bell-striking member 7 is a rotating shaft 7.
a and a hitting ball 7b which is freely movably attached thereto. A motor shaft 8a of the drive motor passes through the upper frame portion 13 and projects into the interior of the ring 2, and a rotating shaft 7a is connected to the projecting end.
As shown in the second figure, U-shaped elastic parts 13a, 13a are integrally formed in the upper frame part 13, and operating protrusions 13b, 13b and their tips are attached to the elastic parts outward. The locking protrusions 13c, 13c
is formed. The operation projections 13b, 13b penetrate the rear frame portion 12 and can be operated from the outside, and the locking projections 13c, 13c can be locked in locking grooves 3c, 3c formed on the inner surface of the stop button 3. .

A watch circuit block 10 for controlling a liquid crystal panel 9 within a display window 11a provided in a front frame portion 11 is housed within the watch case 1. This clock circuit block 10 is equipped with an alarm device,
A drive motor 8 is operated by the alarm signal to drive the bell striking member 7. The operation buttons 20... are used to adjust the time, set an alarm time, etc. 21 is a printed circuit board that constitutes a drive circuit of the timepiece device. The battery E is stored in a battery storage chamber 22. 23 is a small battery cover.

The alarm time is set by operating the operation button 20. After completing the setting, move the stop button 3 to the alarm set position (upper position). That is, when the operation protrusions 13b, 13b shown in the second figure are pressed, the elastic parts 13a, 1
3a is bent, and the locking protrusions 13c, 13c are removed from the locking grooves 3c, 3c. Then, the ring stop button 3 is displaced upward by the spring force of the return spring 5, and as shown in the first figure, the ring stop button 3 and the watch case 1 are separated, and the ring 2 is visible from the outside through this gap. becomes. This upper position is the alarm set state, and since the outer surface of the ring 2 is colored extremely conspicuously against the outer surfaces of the watch case 1 and the ring stop button 3, the ring 2 stands out from the outside in the alarm set state. The alarm setting status can be checked at a glance. When the alarm time comes and an alarm signal is supplied from the clock circuit block 10 to the drive motor 8, the ring 2 is struck by the bell striking member 7. To stop the ringing, the ringer button 3 is returned and pushed down against the spring 5.
When the stop button 3 descends, the switch pressing piece 32 also descends as shown by the chain line in FIG.
The stopper switch 6 is closed by pressing the contact piece 6b against the printed circuit board 6a. This deactivates the alarm circuit. In this noise-stopping state, the locking protrusions 13c, 13c are locked in the locking grooves 3c, 3c (second
(as shown) and held in position. Further, in this state where the sound is stopped, the ring 2 is completely covered by the sound stop button 3 and cannot be visually recognized from the outside.

Note that the bell striking member may be of a lever type, and in that case, the driving means thereof may be of an electromagnetic type. It is also possible to arrange the driving means for the bell striking member inside the ring.

(Effect of the invention) The present invention is constructed as described above, and in the alarm set state, the stop button moves to the upper position and the ring can be seen from the outside, so it can be seen at a glance that the alarm is in the alarm set state. is recognized, and the striking sound is also emitted from the gap, resulting in a loud alarm sound. In addition, the ring stop operation is extremely easy, and in the ring stop state, the ring stop button becomes part of the watch case, giving it a unified appearance.
