Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a foldable electric device.

2. Description of the Related Art Conventionally, there is an electric device that uses a battery as a power source and can be folded so as to be small when carried. In such an electric device, the battery is housed in the upper cabinet or the lower cabinet.

Hereinafter, a foldable cordless telephone of the above-described conventional electric devices will be described as an example with reference to the drawings.

FIG. 4 is a perspective view of a conventional foldable cordless telephone in use. FIG. 5 is a side sectional view showing a conventional cordless telephone in a folded state. In FIGS. 4 and 5, reference numeral 1 is an upper cabinet, and 2 is a hinge portion for connecting the upper cabinet 1 and the lower cabinet 3 to each other so as to be rotatable. Reference numeral 4 is a speaker, 5 is an operation unit provided with dial buttons, 6 is a microphone, 7 is a battery for supplying electric power necessary for the operation of the cordless telephone,
Reference numeral 8 is a storage portion for the battery 7.

The foldable cordless telephone configured as described above is in a state of being opened as shown in FIG. 4 by rotating the upper cabinet 1 and the lower cabinet 3 about the hinge portion 2 during use, that is, during a call or dial operation. In addition, when carrying, the upper cabinet 1 and the lower cabinet 2 were rotated around the hinge portion 2 as an axis to be closed as shown in FIG.

Problems to be Solved by the Invention However, in the above configuration, the upper cabinet 1
In order to store the battery 7 in the internal battery storage portion 8, the thickness of the upper cabinet 1 needs to be at least a thickness capable of storing the battery, that is, a dimension equal to or larger than the diameter of the battery. For this reason, the upper cabinet 1 becomes thick, and it is difficult to make the electric device small. The lower cabinet also needs to have a certain thickness, especially if the printed wiring boards need to be housed in both the upper and lower cabinets.
When the upper cabinet and the lower cabinet were closed so that they overlap each other, the thickness was extremely thick.

The present invention has been made in view of the above prior art, and provides an electric device having a small thickness when closed.

Means for Solving the Problems In order to achieve this object, an electric device of the present invention is used for a portable telephone using a battery as an operating power source, and has an annular screw number part and an operating part. An upper cabinet having
A lower cabinet having an annular screw number portion, an elongated cylindrical battery storage container having a battery terminal at the bottom, and a battery lid equipped with the battery terminal and fitted to the other bottom of the battery storage container, When the screw number part of the upper cabinet and the screw number part of the lower cabinet are attached to the storage container as an axis and the screw numbers are turned to overlap the upper cabinet and the lower cabinet, the lower cabinet is replaced by the upper cabinet. The operation section is covered and the thickness of the upper cabinet and the lower cabinet overlapped is equal to the outermost diameter of the screw number section.

Embodiment An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is an exploded perspective view of a foldable cordless telephone according to an embodiment of the present invention. FIG. 2 is a perspective view of the cordless telephone, and FIG. 3 is a side sectional view showing the folded state of the cordless telephone. 1 to 3
In the figure, 9 is an upper cabinet, and 10 is a hinge portion that rotatably connects the upper cabinet 9 and the lower cabinet 11 to each other. The upper cabinet 9 and the lower cabinet 11 each have a thickness of about half the diameter of the hinge portion 10. Reference numeral 12 denotes a battery storage pipe that serves as a rotation axis of the hinge portion 10. One end is closed and the battery storage pipe 13
Is stored. It is desirable that the diameter of the battery storage pipe 12 is as small as possible within the range in which the battery 13 can be stored. A spring terminal 14 connected to one terminal of the battery 13 is attached to one end of the battery housing pipe 12. Reference numeral 15 denotes a battery lid, which is fitted in the open end of the battery housing pipe 12 so as to be directly detachable, and has a terminal connected to the other terminal of the battery 13 attached thereto. The spring terminals 14 and the terminals provided on the battery lid 15 are connected to electronic circuits provided in the upper cabinet 9 and the lower cabinet 11, respectively. 16 is a speaker, 17 is an operation unit such as a dial key, and 18 is a microphone. Since the configuration of the speaker 16, the operation unit 17, and the microphone 18 is general, detailed description thereof will be omitted here.

The operation of the cordless telephone configured as above will be described below.

First, when making a call, the upper cabinet 9 and the lower cabinet 11 are rotated to each other, and the upper cabinet 9 and the lower cabinet 11 are opened to each other as shown in FIG. Then, the operation unit 17 is operated to transmit a dial signal or perform on-hook or off-hook operation. When the call ends, the upper cabinet 9 and the lower cabinet 11 are turned to be in the closed state. In this state, the thickness of the cordless telephone is almost equal to the diameter of the hinge portion 10, so that the thickness of the cordless telephone is slightly larger than the diameter of the battery. Further, since the operation unit 17 is covered with the lower cabinet 11, there is no need to perform an inadvertent operation. After the battery is used for a long period of time, if the battery 13 becomes weak, open the battery lid 15 and replace the battery 13 with a new one.

EFFECTS OF THE INVENTION As described above, according to the present invention, the pivot shaft of the hinge is hollow and the battery is housed therein, so that the battery can be housed in any of the plurality of cabinets coupled via the hinge portion. Since the thickness of each cabinet can be made smaller than the diameter of the battery, the sum of the thicknesses of the upper cabinet and the lower cabinet can be made almost the same as the diameter of the battery, and it can be thin when folded. It is possible to provide a foldable electric device that is thick and does not require careless operation.
