Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an alarm clock, and particularly to an improvement in its alarm operating mechanism.

[Prior Art] Alarm clocks that issue an alarm at a predetermined time have been well known, and have been widely used in households as alarm clocks that emit a bell or the like when it is time to wake up, for example.

This type of alarm clock is equipped with an alarm operation switch button on the outside of the watch frame to control the alarm action, and the operator can stop the alarm action as desired by operating this switch button. It becomes possible to control the

However, arranging this alarm operation switch button on the outer surface of the frame of the watch not only increases the manufacturing cost due to an increase in the number of parts, but also impairs the aesthetic appearance of the watch itself.

Moreover, if the switch button is placed on the back side of the frame, the aesthetic appearance can be prevented, but the operability of the switch button will be reduced.

Therefore, in the past, alarm clocks have been devised in which alarm control can be performed by using the windshield itself that covers the time display plate as a switch operation part.

FIG. 5 shows a windshield operated alarm clock described in Japanese Utility Model Application Publication No. 59-101335.

The alarm clock shown in the figure includes a frame 12 for fixing a clock mechanism body 10 having a built-in alarm mechanism, and a windshield 16 that covers a time display plate 14 provided on the front surface of the frame 12.

The lower end 16a of the windshield 16 is connected to the frame 1
The upper end is locked to an engagement hole 12a provided in 2 so as to be tiltable about this hole 12a as a fulcrum.

The upper end 16b of the windshield 16 is connected to the frame 1
The alarm operating switch 18 is inserted into the frame 12, and the contacts 18a and 18b of the alarm operation switch 18 provided in the frame 12 can be pressed into contact with each other.

In the alarm clock configured as described above, for example, when the alarm action is to be stopped, the operator presses the top of the windshield 16 in the direction of arrow A to control the alarm operation switch 18 on and off. A desired control state can be obtained.

According to the alarm clock as described above, there is no need to expose the switch button for operating the alarm outside the frame, which has the advantage of reducing the number of parts and improving the aesthetic appearance of the clock itself.

[Problems to be Solved by the Invention] However, in the alarm clock as shown in FIG. Even if the operating switch can be operated correctly and other parts are pressed, there is a problem in that the alarm cannot be controlled smoothly.

Moreover, in conventional alarm clocks, in order to set the alarm time, it is necessary to operate a knob 20 etc. provided on the back of the clock, which increases the number of parts and causes problems such as poor operability. Ta.

The present invention was developed in view of the conventional problems mentioned above, and its purpose is to enable switching control of the alarm operation switch by pressing down on the windshield at any position, and to easily set the alarm time. Our goal is to provide an alarm clock that is easy to operate.

[Means for Solving the Problems] In order to achieve the above object, the alarm clock according to the present invention has a windshield protruding from the upper surface of the frame in a dome shape and held in the frame so that it can move up and down and rotate. has been done.

Furthermore, the alarm time setting section is provided with a flat section on the outer periphery of the tip of the shaft and whose outer cross-sectional shape is non-circular.

A transparent reference display board is rotatably arranged at a predetermined distance above the time display board, and has an alarm time display section in a part of which sets the alarm time depending on the rotational position of the display board. It is fixed to the windshield so as to rotate in conjunction with the rotation of the glass. Further, a shaft body is provided which rotates in conjunction with the guide display board and sets an alarm time in the alarm mechanism.

Also, provided within the frame are an alarm operation ring that moves up and down in conjunction with the up and down movement of the windshield, and an alarm operation switch that is switched and operated by the up and down movement of the alarm operation ring and controls the operation of the alarm mechanism. It is characterized by the presence of

[Function] As is clear from the above-described configuration, according to the alarm clock according to the present invention, by rotating the windshield glass that covers the time display board provided on the top surface of the frame, the guide display board is rotated. You can change the location and set the alarm time at the desired time.

Furthermore, by pushing down the windshield from any direction, an alarm operation ring provided within the frame is moved up and down, and the alarm operation switch can be switched by moving the alarm operation ring up and down.

Therefore, according to the alarm clock according to the present invention, it is possible to control the alarm without providing a special switch button on the outside of the frame, so that the number of parts can be reduced and the appearance of the clock can be improved.

Further, since the alarm operation switch can be operated no matter which part of the windshield is pressed, the operability of alarm control is also greatly improved.

Furthermore, since the alarm time can be set by rotating the windshield, the alarm time can be set with a simple operation without requiring a special alarm time setting knob or the like.
