Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a battery holding device, and more particularly to a battery holding device capable of holding batteries of various sizes and standards.

As is well known, devices that use batteries as a power source (for example, small radio receivers) can only use batteries of a predetermined standard.

Therefore, if there is no spare battery of a predetermined standard and an external commercial power source cannot be used, the device becomes unusable if the battery housed in the device discharges.
If you are able to use batteries of other standards in such cases, you can use batteries removed from other devices that are not in use or batteries that are kept in stock to avoid being concerned about the standard, and to use them in case of disasters, etc. This is extremely convenient as it can be worn and used in an emergency. Furthermore, when purchasing a gun pond at a store, it is very convenient to be able to obtain and use batteries of any size without worrying about the battery specifications. Therefore, in order to be able to arbitrarily use batteries of multiple standards, for example, as shown in Figs.
~ The front wall 5 of the battery storage section 4 has a two-tiered structure according to the length in the longitudinal direction of the AA batteries 1 to 3, and the above-mentioned dry batteries 1 to 3 are placed on both side walls 6 and 7 of the battery storage section 4. A battery holding device is conventionally known, which is provided with bond surfaces 8 to 10 each having a shape corresponding to a part of the outer circumferential surface of cell 3. However, a battery holding device having such a structure has the disadvantage that the device occupies a large space, resulting in an increase in the size of the device. Furthermore, although the AA battery 1 can be easily held down by the cover 11 that covers the battery compartment 4, special holding means must be provided in order to hold down the AA and AA batteries 2 and 3. Therefore, the structure is complicated, and the operation of attaching and detaching the dry batteries 2 and 3 is troublesome, resulting in poor operability. Moreover, after the battery 2 or 3 is installed, it is easily removed from the normal installation position due to unexpected vibrations, shocks, etc., resulting in a problem of lack of reliability. The present invention was invented in view of the above-mentioned circumstances, and it is possible to reduce the space occupied by the device, provide high operability and reliability in attaching and detaching the battery, and securely hold the battery.

The cam grooves 36 are opposite to each other, respectively. In addition, to explain these cam grooves 35, 36 in more detail, first, a slide portion village 16 is provided approximately in the center of the cam grooves 35, 36.
Horizontal twilling portions 35a and 36a extending in the longitudinal direction are provided, respectively. At both ends of these horizontal grooves 35a, there are inclined grooves 35b and 35c extending substantially parallel to each other in a direction intersecting (inclining) with the longitudinal direction of the slide member 16 and sloping upward to the right in FIGS. 4 to 6. They are formed in succession. Similarly to this, the horizontal groove portion 36a
The above-mentioned inclined groove portions 36b and 36c are continuously formed in both portions. Furthermore, a horizontal groove portion 35d extending parallel to the horizontal twilling portion 35a is continuously formed at the top of the inclined groove portion 35c of the cam groove 35.

Furthermore, a pair of cylindrical projections 43 are integrally molded on both sides of the terminal support member 18, as in the case of the battery Atsushi member 17 described above. Next, to explain the configuration of the battery holding device after assembly is completed, first, the slide member 16
is mounted inside the base 15 so as to be movable in the longitudinal direction (horizontal direction in FIGS. 4 to 6) with respect to the base 15 fixed to the cabinet or chassis (not shown) of the equipment.

That is, the knob 34 of the slide member 16 is disposed so as to be able to pass through the opening 25 of the base body 15 and move in the longitudinal direction within the closing mouth 25, and the bottom plate 31 of the slide member 16 is placed on the protrusion 24 of the base body 15. The pair of terminal attachment portions 22 of the base body 15 are inserted into the pair of notches 33 of the slide member 16.
located within. This slide member 16 is prevented from falling off from the base body 15 by a protrusion 28 of the base body 15. The above-mentioned knob 34 protrudes outward from the bottom of the equipment cabinet, and can be operated from the bottom of the equipment. On the other hand, the fourth
As shown in FIGS. 6 to 6, the cylindrical protrusions 40 of the battery charger member 17 pass through the cam grooves 35 of the slide member 16 and are respectively engaged in the vertical registers 26 of the base body 15. The battle layer member 17 is supported by the slide member 16 in a vertically movable manner as described later.

Also, on the same machine, the cylindrical protrusion 43 of the terminal support member 18
penetrates the cam groove 36 of the slide member 16 and engages in the dogleg-shaped guide groove 27 of the base body 15, thereby causing the terminal support member 18 to move in a direction intersecting the above-mentioned vertical direction as described later. It is supported by the slide member 16 in a possible state. Although not shown in the drawings, the battery holding device is provided with a lid as is known in the art, and an elastic member such as a sponge is attached to the back of the lid, and when the lid is closed, this elastic member This allows the battery to be held in place.

Next, the battery holding operation of the battery holding device configured as above will be described. First, when storing two AA batteries 1, before placing the batteries 1 on the mounting surface 17a of the battery placement member 17, move the knob 34 of the slide section 16 to the right side as shown in FIG. Move it to the edge.

Along with this, the slide member 16 slides in the direction of arrow A in FIG. 4, so that the battery battle layer member 17 is moved to the lower position. - That is, as the slide member 16 moves in the direction of arrow A, the cylindrical projection 4 of the battery teaching layer member 17
0 is the inclined groove portion 35b of the cam groove 35 of the slide member 16,
35c in a direction perpendicular to the inclined grooves 35b, 35c and downward, these cylindrical projections 40 are guided by the vertical guide grooves 26 of the base body 15 and moved in the direction of arrow B. That will happen. As a result, the protrusion 40 is disposed and supported at the lowest end of the inclined groove portion 35b and the vertical guide groove 26, so that the battery layer member 17 is disposed at a lower position as shown in FIG. Therefore, if a single dry cell battery 1 with a large diameter is placed on the Kasumiike layering member 17, the dry cell battery 1 will be
can be pressed toward the war calendar surface 17a. At the same time, as the slide member 16 moves in the direction of arrow A, the cylindrical protrusion 43 of the terminal support member 18 moves between the cam groove 36 of the slide member 16 and the base body 15, as in the case described above. Since the terminal support member 18 is moved to each lower end of the inclined groove portion 27a of the letter-shaped guide groove 27, the terminal support member 18 is placed at the lower position as shown in FIG.

At this time, since the protrusion 43 is moved along the inclined groove portion 27a, the terminal support member 18 is moved in the direction of the arrow C, which intersects the direction of the arrow B, during this time. Therefore, the terminal attachment portion 41 of the terminal support member 18 is substantially moved away from the terminal attachment portion 22 of the base body 15, and as a result, the distance between the terminal plate 23 and the coil spring 42 becomes wider. As a result, when a single AA dry cell battery 1 with a long longitudinal dimension is placed on the battery education department village 17,
The tip of the coil spring 42 as a terminal comes into contact with the negative electrode of the dry battery 1 and presses it toward the terminal plate 23 with an appropriate force, so that the positive electrode of the dry battery 1 comes into contact with the terminal plate 23. become. In this case, rightward movement of the slide member 16 is prevented by the engagement between the knob 34 and the right side of the Sekiguchi 25, and leftward movement is prevented by the engagement between the knob 34 and the right side of the base 15. Part 29
This is prevented by click engagement with the In this way, the single dry cell battery 1 is stored and held in the battery holding device.

Next, when holding the AA battery 2, move the knob 34 to the left to approximately the center position of the opening square 25, as shown in FIG.

As a result, the pair of protrusions 39a provided on the U-shaped elastic piece 39 of the slide portion village 16 click into engagement between the pair of protrusions 29 of the base body 15, and the slide member 16 is held in this position. Further, as the slide member 16 slides in the direction of arrow A, the cylindrical projection 40 of the battery calendar member 17 is moved upward by the inclined groove 35b of the slide member 16 in a direction perpendicular to the inclined groove 35b. 5, these protrusions 40 are guided by the vertical guide grooves 26 of the base body 15 and moved in the direction of arrow D in FIG. The protrusion 40 is connected to the cam groove 35.
When the slide member 16 reaches the horizontal groove portion 35a, the slide member 16 is locked by click engagement as described above. At the same time, the cylindrical projection 43 of the terminal support member 18 is inserted into the cam groove 3.
Since the terminal supporting member 18 is pressed and biased by the inclined groove part 36b of No. 6 and guided by the inclined groove part 27a of the 〈-shaped guide groove 27 of the base body 15, the terminal supporting member 18 is moved in the direction of the arrow E which intersects with the direction of the above-mentioned arrow D. Moving.

As a result, the coil spring 42 attached to the terminal support member 18 is moved upward in FIG. 5 and in a direction approaching the terminal plate 23. As a result, when a AA battery 2, which has a smaller diameter than a AA battery 1, is placed on the battery teaching member 17, the battery 2 can be held down by closing the lid, and the AA battery 2 can be held down by closing the lid. The AA dry cell battery 2, which is shorter in length than the dry cell battery 1, is connected to the terminal plate 2 by the force of the coil spring 42.
3 side, and the terminal plate 23 and the tips of the coil springs 42 can be brought into contact with the electrodes on both sides of the dry battery 2. In this way, the AA dry battery 2 is held by this device. In this case, since the protrusions 40 and 43 of the battery layer member 17 and the terminal support member 18 are arranged within the horizontal grooves 35a and 36a of the cam grooves 35 and 36, the battery layer member 17 Even if the terminal support member 18 unexpectedly receives a pressing force in the vertical direction, this pressing force releases the click engagement between the projection 29 and the projection 39a, and the sliding member 16 unexpectedly moves. It won't move.

Next, when holding the AA batteries 3, move the knob 34 further to the left as shown in FIG. Moving.

Along with this, the protrusion 40 of the Kasumiike stratification part village 17 is pressed and energized by the inclined groove part 35c of the slide member 16, as in the case described above, and is guided by the vertical guide groove 26 of the base body 15 to move in the direction of the arrow. Move further in the D direction (upward). This protrusion 40 is connected to the horizontal groove 35d of the slide member 16.
The slide member 16 is locked to the base body 15 in the state that the slide member 16 is inserted therein. That is, the movement of the slide member 16 to the left is prevented by the engagement between the knob 34 and the left side of the opening 25, and the movement to the right is prevented by the engagement between the knob 34 and the left side of the opening 25, and the movement to the right is prevented by the engagement between the projection 39a of the slide member 16 and the base 15.
This is prevented by click engagement with the protrusion 29 on one side. On the other hand, the protrusion 43 of the terminal support village 18 is pressed by the inclined groove 36c of the slide member 16 and guided by the vertical groove 27b of the base 15, and moves in the direction of arrow D, which is the same direction as the moving direction of the Kameike mounting member 17. In other words, it is moved upward parallel to the terminal plate 23 of the base body 15.

As a result, the AA dry cell battery 3, which has the same length as the AA dry cell battery 2 and whose diameter is smaller than the AA dry cell battery 2, is remounted on the battery counterfeit member 17 and the lid body is closed. Then, attach this AA battery 3 to the battery platform member 17 with the lid.
The terminal plate 23 and the tips of the coil springs 42 can be brought into contact with the electrodes at both ends of the dry battery 3. In this way, the AA dry battery 3 is held by this device. Note that in this case as well, the projections 40 and 43 are arranged in the horizontal grooves 35d and 36d, so that the exposed pond layer member 1
7 and the terminal support member 18 are unexpectedly pressed downward,
The slide member 16 will not move unexpectedly due to this pressing force. According to the battery holding device configured as described above, it is possible to arbitrarily use AA to AA dry batteries 1 to 3 by simply providing a space that can accommodate the AA dry battery 1, and moreover, this device occupies This is advantageous in terms of space factor because the space can be kept small.

In addition, since all you have to do is move the knob 34 on the slide member 16 according to the dry battery of various standards, the operation is very simple and has good operability.In addition, the battery can be held securely, so the reliability is very good. There are advantages. The present invention as described above-
Although the embodiment has been described, the present invention is not limited to this embodiment, and various modifications can be made based on the technical idea of the present invention.

For example, in this embodiment, only the terminal plate 23 and the coil spring 42 that should come into contact with the exposed electrodes at both ends of the dry batteries 1 to 3 are configured to be movable, but the present invention is not limited to this, and both of these can be moved. It may be possible to configure. In addition, the cam grooves 35 and 36 of the slide member 16 and the base body 1
The shapes of the guide books 26 and 27 of No. 5 may be changed in various ways.
Further, in this embodiment, the structure is configured to be able to hold AA to AA dry batteries 1 to 3, but in addition to this, it is also possible to be configured to be able to hold standard dry batteries such as AAA. It goes without saying that the present invention is applicable not only to battery holding devices for radio receivers, but also to various electronic devices such as tape recorders and VTRs. As described above, the present invention moves the battery platform member in a predetermined direction by interlocking with the movement of the slide member movably provided within the base, and also moves the terminal support member at least crosswise to the predetermined direction. It is configured so that it can be moved in the direction of Therefore, according to the battery holding device of the present invention, it is possible to hold a plurality of types of batteries with different standards, and it is only necessary to provide a space that can accommodate the battery with the largest diameter among the batteries to be held. , the space occupied by the device can be reduced by 4 mm, which is very advantageous in terms of space factor. Furthermore, since batteries of various standards can be installed simply by moving the slide member, the device has the advantage of very good operability.
