Description

[Detailed description of the invention]

[0001]

[Industrial applications]

 The present invention relates to an alarm clock in which a portable electric lamp is detachably combined.

[0002]

[Prior art]

 In the past, there have been cases where the power supply for the flashlight and the power supply for the alarm clock were separate and simply combined. There were also alarm clocks that themselves became luminous bodies (earthquake lights and alarm clocks in Japanese Utility Model Publication No. 61-2950, and portable electric light / timepiece clocks in Japanese Utility Model Publication No. 4-7521).

[0003]

[Problems to be solved by the device]

 In a normal home, there are few people who have an alarm clock in their reach, such as a bedside at bedtime, even if they have an alarm clock. The current situation is to put it in place. In addition, there are few people who live alone, such as boarding students, singles, and single employees, who have an alarm clock but a flashlight. For this reason, many people not only feel fear in the dark, but also cannot move easily when a sudden power outage due to a natural disaster such as a large earthquake at midnight, which may cause a secondary disaster.

As described above, the combination of the flashlight and the power source of the alarm clock, which are separately combined, becomes large and heavy, and the appearance and the fashionability and character of the alarm clock are impaired. When the alarm clock itself is used as a light emitter, when it is used as an illuminating lamp, it does not utilize light reflection effectively, so the irradiation efficiency is low and there is the inconvenience of carrying the alarm clock itself.

Therefore, when it is used as a portable electric lamp, the irradiation effect is improved, and the battery-operated alarm clock is simple and compact without impairing the fashionability and character of the alarm clock. It is provided as a detachable combination of portable lights.

[0006]

[Means for Solving the Problems]

 A portable electric lamp containing a battery is detachably mounted inside the alarm clock, and the alarm clock is driven by using the battery of the portable electric lamp as a power source. The first aspect of the present invention is the rectangular frame surface of the portable electric lamp. One side of the alarm clock is fixed to the inside of the alarm clock so that it can be inserted into and removed from the other side of the alarm clock, and the other end is a thin square that elastically presses against the positive and negative electrodes of the battery. It is characterized by attaching the lead plate of. A second aspect of the present invention is characterized in that a plug adapter integrally formed on the inner surface of the rectangular frame of the portable electric lamp is provided, and on the other hand, inside the alarm clock, a pin plug that can be brought into contact with and separated from the plug adapter is attached.

[0007]

[Action]

 Since the present invention has taken the above-mentioned means, if a portable electric lamp is mounted inside the alarm clock, the first aspect of the present invention is to use a lead plate that presses against the positive and negative electrodes of the battery of the portable electric lamp. In the second, the plug adapter that press-contacts with the pin plug can supply the driving power to the alarm clock from the battery of the portable electric lamp, as an alarm clock in everyday life, and pull out the portable electric lamp from the alarm clock in an emergency. As a result, the lead plate or pin plug that was press-contacted can be removed, and it can be used alone as an illumination lamp.
