FIG. 5 is a cross-sectional view showing the accommodated state of the C-size batteries in the first and second embodiments, and FIGS. 6A to 6D are a front view, a side view, and a plan view showing the third embodiment of the present invention. FIG. 7 is a cross-sectional view, a partial perspective view, and FIG. 7 is a cross-sectional view showing a state where AA batteries are housed in the third embodiment.

Referring to FIG. 1, a first embodiment of the present invention is a dry battery adapter in an electric appliance using a single dry battery. This adapter is a single 1 dry power of electrical equipment
It is installed in the space that houses the pond and has a single outside diameter.
A cylinder 1 having the same size (single size 1a) as the outer dimensions of the dry cell and having the same inner diameter (single size 2a) as the outer dimensions of the C2 dry cell 2 as shown in FIG.
A thick portion 1e is formed at a portion between the outer diameter portion and the inner diameter portion,
A C-cell battery 2 is housed in the inner periphery of the cylinder 1. In this case, as shown in FIG. 5, the cylinder 1 is divided into two semicircular shapes while leaving a part as the hinge portion 1b, and the C-cell dry battery 2 is rotated in one half of the semicircular shape while rotating around the hinge portion 1b. When the battery is housed in the side 1c and the other side 1d is closed, the separated portion at the symmetrical position with the hinge 1b is fastened by the hook 7, so that the C-cell 2 is housed in the cylinder 1.

As shown in FIG. 2, the sliding portion 5 has two thick portions symmetrical with respect to the center of the cylinder 1 with a predetermined circumferential length and a notch in the longitudinal direction. A central cavity of the cylinder 1 formed by rotatably hinged a slide part 5 having a shape to a notch portion and rotating the two slide parts 5 hinged at symmetric positions into the inside of the cylinder 1. The AA battery 3 is stored in the 11 AA size 3a,
The AA battery 3 is inserted from the AA battery insertion slot 13 shown in FIG. In addition, dry battery brackets (+) provided above and below the cylinder 1
8 and the dry battery spring (-) 9 are pressed from above and below, so that the AA batteries 2 and the AA batteries 3 are stored in the cylinder 1 without play. As described above, both the AA battery 2 and the AA battery 3 can be stored in the adapter of the cylinder 1 having the same outer diameter as the AA battery.

Next, FIG. 3 shows a second embodiment of the present invention. Two slide portions 6 longer than the slide portion 5 of the first embodiment are provided in contrast to the thick portion 1e of the cylinder 1, and each of the slide portions 6 is formed by rotating the slide portion 6 inside. AAA size 4a in the central space 12 of the cylinder 1
Is a structure in which the AAA battery 4 is stored. As described above, both the C-size battery 2 and the AAA-size battery 4 can be accommodated in the adapter of the cylinder 1 having the same external dimensions as the size-A size battery.

FIG. 6 shows a third embodiment of the present invention.

Referring to FIG. 6, the third embodiment is a battery adapter for an electric device using a C-cell, and is mounted in a space for accommodating a C-cell of the electric device.
The size of the AA battery 3 is the same as the outer size of the AA battery 2 (the size 2a) and the inner diameter is
A cylindrical portion 10 having the same size (AA size 3a) as the outer dimensions of the outer diameter portion and the inner diameter portion as shown in FIG.
And a thick portion 10e is formed between
AA batteries 3 are stored in the inner peripheral portion of the battery. In this case, as shown in FIG. 7, the cylinder 10 is divided into two semicircular shapes while leaving a part thereof as a hinge portion 10b. When the battery is housed in the side 10c and the other side 10d is closed, the AA battery 3 is housed in the cylinder 10 by fastening the hook 17 to the separated portion symmetrically to the hinge 10b.

As shown in FIG. 3C, the slide portion 14 has two thick portions symmetrical with respect to the center of the cylinder 10 with a predetermined circumferential length and a notch in a longitudinal direction. Of the cylinder 10 formed by rotatably hinged to the notch portion a slide portion 14 having exactly the same shape as that of the notch portion, and rotating the two slide portions 14 hinged at symmetrical positions inside the cylinder 10, respectively. AAA in the AAA size 4a part of the central space 15
The dry battery 4 is stored, and the AA or AAA battery
Insert AA battery 3 or AAA battery 4. In addition, referring to the dry cell mounting diagram of FIG. 6D, the size difference 19 occurs in the vertical direction because the length of the AAA battery 4 is short.
The "-" side spring member 18 is provided to push up the AAA battery 4,
The electrodes can be in constant contact. in this way,
Both the AA battery 3 and the AAA battery 4 can be stored in the adapter of the cylinder 10 having the same external dimensions as the AA battery.

[0022]

The first effect is that, in an electric device using a dry battery, even when there is no designated dry battery, it can be operated in the event of a disaster or emergency by using other types of familiar dry batteries. Becomes

The reason is that the adapter for the AA battery can accommodate any of the AA batteries, the AA batteries, and the AA batteries,
This is because both the AA and AAA batteries can be stored in the battery adapter.

As the second effect, the first effect can be obtained without particularly increasing the size of the electric equipment to be used.

The reason is that the adapter has a cylindrical shape, and a means for accommodating a dry battery by rotating a slide portion provided in a thick portion thereof into the cylinder is provided.
