DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a battery case for electric equipment, and more particularly, to the structure of a single, C, and AA common battery case.

[0002]

2. Description of the Related Art An example of a conventional dry battery case will be described with reference to FIG. FIG. 8 is a perspective view showing the structure of a conventional dry battery case. Inside the case body 5, there are provided terminals 5a which are common for C2 and AA, and a spacer 6 which can be mounted. In order to be able to store two AA batteries or two AA batteries in parallel, the dimensions between the AA and AA shared terminals 5a and the corresponding AA and AA shared terminals 5a are It is the same as the total length of the two batteries or AA batteries.
(The overall length of the AA battery is the same as that of the AA battery.) The height from the common terminal 5a to the bottom of the case body 5 is equal to or greater than the radius of the AA battery. The dimensions of The spacer 6 is provided with a recess corresponding to the curved surface of the AA battery. AA batteries are stored in a state where the spacers 6 are set up and the curved surfaces of the AA batteries are applied to the recesses of the spacers 6. The storage of the C-cell is performed with the spacer 6 removed or laid down.

[0003]

In the above-mentioned conventional dry battery case, it is possible to store AA and AA dry batteries having the same overall length, but there is a drawback that a single dry battery cannot be stored. .

Accordingly, an object of the present invention is to provide an extremely convenient dry battery case capable of accommodating not only AA and AA batteries but also a single battery.

[0005]

SUMMARY OF THE INVENTION In order to achieve the above objects, the present invention has a concave portion on the front and back that fits a curved surface of a single battery, a concave portion on a right side and a left side that fits a curved surface of a single battery, and a bottom surface. A supporting unit base having a concave portion that fits the curved surface of an AA battery and detachable from a case body is used for storing the battery. Further, the battery has a negative electrode spring for a single dry battery, and a negative electrode spring for AA and AA dry batteries mounted on a surface opposite to a mounting surface of the negative electrode spring for a single dry battery, and has a L-shaped cross section. An anode adapter detachable from the case body is used for storing dry batteries. The mounting direction of the support base and the negative electrode adapter can be changed according to the dry batteries to be stored. In other words, the support unit mounts a concave portion that fits the curved surface of the dry battery to be stored facing the longitudinal direction of the case body, and the negative electrode adapter stores a single dry battery or a single AA battery or a single AA battery. And the mounting direction is changed. For example, when storing a single dry battery, the negative electrode adapter is mounted with the negative spring for the single dry battery facing the positive terminal. Then, the dimension between the negative electrode spring for a single dry battery and the positive electrode terminal at the time of mounting is set to be an integral multiple of the overall length of the single dry battery. On the other hand, when accommodating AA batteries or AA batteries, the negative electrode adapter is mounted with the negative electrode spring for AA or AA batteries facing the positive electrode terminal. And the size between the negative electrode spring and the positive electrode terminal for AA and AA batteries at the time of mounting,
Alternatively, the length is an integral multiple of the total length of the AA battery.

In this embodiment, the case where two dry batteries are housed in series has been described, but the present invention is not limited to this. Even when three or more dry batteries are stored in series, two or more dry batteries are stored in parallel, and only one dry battery is stored, the same can be achieved by using the support base and the negative electrode adapter. , AA batteries can be stored.

Further, the present embodiment has been described with respect to an example corresponding to a single, AA, or AA battery, but the present invention is not limited to this. Of the three types of batteries, if the total length of the two types of batteries is the same, the same applies to the three types of batteries.
It can accommodate various types of dry batteries.

[0013]

According to the present invention, not only AA and AA batteries but also a single battery can be accommodated (a single, AA and AA shared battery case can be provided).
This eliminates the need to prepare a dedicated storage case for each dry battery. Therefore, whether it is a single battery or a single
As long as any one of the AA batteries is stored, an extremely convenient dry battery case that can operate the electric equipment even in an emergency, for example, can be provided.
