[0015]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the drawings.

Referring to FIG. 1, it is assumed that a predetermined dry cell is a C-cell (specific dry cell) in an apparatus using dry cells such as electric and electronic equipment. In this case, for example, if there are AA batteries (separate batteries) but there are no AA batteries, the device using the batteries cannot be used. At this time, it is very convenient if AA batteries can be used.

The dry battery case device 11 shown in FIGS. 1A and 1B is a cylindrical case body, and is formed of, for example, an insulating material (for example, resin (plastic) or wood). The diameter of the dry battery case device 11 is the same as the diameter of a columnar C-size dry battery (not shown). A cylindrical hollow portion 12 is formed in the dry battery case device 11.
The diameter of the hollow portion 12 is substantially the same as the diameter of the cylindrical AA battery (preferably slightly larger than the diameter of the AA battery).

Generally, an AA battery has an anode at one end and a cathode at the other end. The anode has a protrusion (anode protrusion) extending in the axial direction. The height (length) of the dry battery case device 11 is smaller than the height of the entire AA dry battery by the height of the anode projection. That is, the height of the dry cell case device 11 is (the height of the entire AA dry cell−the height of the anode projection).

When an AA battery is used in a battery-using device using an AA battery, the battery case device 11 described above is used.
Insert the AA battery in the hollow portion 12 of the above (the AA battery is inserted into the hollow portion 12, and the diameter of the hollow portion 12 is set to the diameter of the AA battery so that the AA battery does not easily come out of the hollow portion 12. It is desirable to make it slightly larger than that).

As described above, when the AA battery is inserted into the battery case device 11, the state shown in FIG. In other words, in the drawing, the anode projection projects from the upper end of the dry cell case device 11. After inserting the AA batteries into the battery case device 11 in this manner, the battery case device 1
1 is inserted into a device using dry cells using C-size batteries (inserted into the battery storage section of the device using dry cells). Since the diameter of the dry cell case device 11 is equal to the diameter of the C-size dry cell and the height thereof is shorter by the height of the anode projection, the dry cell case device 11 fits completely in the battery storage section of the dry cell device. As a result, AA batteries can be used in a battery-using device that uses AA batteries.

In the above description, the height (length) of the dry cell case device 11 is assumed to be equal to the height of the AA battery. However, if the height of the dry battery case device 11 is shorter than the AA battery, there is a problem. Absent. That is, the height of the dry cell case device 11 does not have to exceed the height of the AA dry cell.

Further, although the dry battery case device 11 is formed of an insulating material, a metal or the like may be used. At this time, it is necessary to prevent the anode and the cathode of the AA battery from contacting the battery case device 11,
Generally, AA batteries are insulated by an insulating material (insulating tape) except for the anode and the cathode, and therefore have no problem. In the above description, the height of the dry battery case device 11 is (the height of the entire AA battery—the height of the anode projection). May be made equal to the height of the object. That is,
In the battery accommodating part of the device using the dry battery, since the electrodes are formed by the elastic body of the spring member, even if the height of the dry battery case device 11 is equal to the height of the entire AA battery, the anode and the cathode of the AA battery Will come into contact with the electrodes of the battery housing.

Next, another example of the dry battery case device according to the present invention will be described with reference to FIG.

Now, it is assumed that a predetermined dry battery is a single dry battery (special dry battery) in a device using dry batteries. In this case, for example, if there is an AA battery or an AA battery but there is no single battery, the device using the battery cannot be used.

The illustrated dry battery case device 21 is a case body having a cylindrical appearance, and is formed of, for example, an insulating material (for example, resin (plastic) or wood).
The diameter of the dry battery case device 21 is the same as the diameter of a cylindrical single dry battery (not shown), and its height (length) is equal to the height of the single dry battery. The dry battery case device 21 includes:
It has a main body 21a and a cap 21b, and the cap 21b is separable from the main body 21a.

A hollow portion 21c having a diameter substantially equal to the diameter of the C-cell is formed in the main body portion 21a. Similarly, a hollow portion having a diameter substantially equal to the diameter of the C-cell is formed in the cap portion 21b. 21d is formed (hollow portions 21c and 2c).
It is desirable that the diameter of 1d is slightly larger than the diameter of the AA battery.

One end of the main body 21a is closed,
At one end, for example, a cathode 22 is formed. That is, one end surface of the main body 21a is closed by the cathode 22, and inside the main body 21a, the cathode 22 is provided with a spiral spring (spring) 23 extending in the axial direction. The periphery of the cathode 22 is insulated.

Similarly, one end of the cap portion 21b is closed, and an anode 24 is formed at this one end, for example. That is, one end surface of the cap portion 21b is
4, a plate spring 25 is provided on the anode 24 inside the cap portion 21b. The periphery of the anode 24 is insulated.

When a C-cell is used in a battery-using device using a single-cell battery, the C-cell is inserted into the hollow portion 21c from the cathode side through the opening of the main body 21a of the above-mentioned dry-cell case device 21. I do. Then, the cap portion 21b
Is put on the main body 21a from the opening side. For example, the main body 21a and the cap 21b are each threaded on the opening side, and the cap 21b is mounted on the main body 21a by screwing the cap 21b into the main body 21a. When the cap 21b is attached to the main body 21a in this manner, the height of the dry battery case device 21 becomes equal to the height of a single battery. At this time, the anode of the C-cell is in contact with the anode 25 through the leaf spring 25, and the cathode of the C-cell is in contact with the cathode 22 through the spring 23.

After the AA batteries are stored in the battery case device 21 as described above, the battery case device 21 is inserted into a battery-using device that uses a single battery (in the battery storage section of the battery-using device). insert). Since the diameter of the dry battery case device 21 is equal to the diameter of the single dry battery and the height thereof is equal to the height of the single dry battery, the dry battery case device 21 fits completely in the battery storage portion of the dry battery-using device. As a result, C-cell batteries can be used in a battery-using device that uses a single cell.

When an AA battery is used in a battery-using device using a single battery, the battery case device 11 described above is used.
After the AA batteries are stored in the battery case device 11, the dry battery case device 11 may be stored in the dry battery case device 21.

In the above description, an example was described in which a cathode was formed on the main body 21a and an anode was formed on the cap 21b. However, an anode was formed on the main body 21a, and a cathode was formed on the cap 21b. You may do so. Also,
The joining between the main body 21a and the cap 21b is not limited to screwing, and the cap 21b can be opened and closed with respect to other mounting methods, for example, the main body 21a. The main body 21a is opened by moving the main body 21a, and the batteries are stored in the main body 21a.
The main body 21a may be closed at 1b.

In the above description, the dry cell case device 21 is formed of an insulating material, but a metal or the like may be used. In this case, it is necessary to insulate the cathode 22 and the anode 24 from other parts of the dry cell case device 21.

As can be easily understood from the above description,
When another dry battery (for example, AA battery) having a smaller thickness than the specific dry battery is used for a device using a specific dry battery (for example, an AA dry battery), the same as the dry battery case device 11 described above. A dry battery case device (first dry battery case) having the above configuration may be used. That is, the diameter of the first dry battery case device may be the diameter of the specific dry battery, and the diameter of the hollow portion formed in the first dry battery case device may be the diameter of another dry battery.

On the other hand, special batteries (for example, single batteries)
When a specific dry battery having a smaller thickness and height (length) than a special dry battery is used as a dry battery using device using a dry battery, a dry battery case device (second Battery case device). That is, the diameter and height of the dry battery case device are made equal to the diameter and height of the special dry battery, and the diameter and height of the hollow portion formed in the dry battery case device are made substantially equal to the diameter and height of the specific dry battery. do it.

Further, when using another dry battery having a smaller thickness and height than the special dry battery in a device using the special dry battery, the other dry battery is inserted into the first dry battery case device, What is necessary is just to accommodate the 1 dry battery case device in the 2nd dry battery case device.

In the above example, the dry cell case device 1
Although the appearance of both 1 and 21 was cylindrical,
Depending on the shape of the battery, the shape may be different. For example, when the dry battery has a square pillar shape, the appearance of the dry battery case devices 11 and 21 becomes a square pillar shape.

[0038]

As described above, the present invention has an effect that another dry battery different from a dry battery specified in advance in a device using a dry battery can be used in the device using the dry battery. Regardless of (shape), if there is a spare battery, you can use equipment using batteries.
