Description

[Detailed Description of the Invention] The present invention relates to a dry cell storage mechanism in which a dry cell is insulated and stored in a case commonly called a fit-up battery holder, which is designed to house a dry cell together with a clock mechanism, and which prevents the dry cell from falling out. It is.

In the past, dry batteries were stored separately from the watch as a product, which required extra storage space and required separate parts for storage.

Therefore, the packaging box as a whole becomes bulky, resulting in high cost including transportation costs.

Furthermore, it was difficult to simplify and standardize the packaging box model, and it took a lot of time and effort to design the packaging each time according to the shape of the product.

For example, in the conventional example shown in FIG. 1, a watch 1 is placed on a lower plate 3 provided with a spring inside a box body 2, and is held down with an upper plate 4 from above. A storage space 5 was formed to store the battery 6 and adhere it with cellophane tape or the like to prevent it from flying out in the front and rear directions.

Therefore, there is a drawback that a wasted space 7 is created in order to form this battery housing space 5.

Particularly in square watches, the wasted space 7 is large.

Furthermore, although cellophane tape or the like is used to prevent the battery 6 from falling off, it has the disadvantage that adhesive strength decreases and the battery becomes sticky due to deterioration during storage.

In the conventional example shown in Fig. 2, a cushioning material 8 such as styrofoam
are appropriately adhesively arranged on the base plate 9 to match the shape of the watch 1, and the watch 1 is fitted and housed therein, and a battery housing space 5 is formed by a separate member 10 at the corner of the base plate 9, and the battery 6 is housed therein. I then secured it with sellotape to prevent it from falling off.

Therefore, this had the disadvantage of wasting a lot of space and requiring separate parts.

In the conventional example shown in FIG. 3, a hole 12 is made in a fitting presser member 11 made of expanded polystyrene to fit the watch 1, and both sides of the watch 1 are fitted and housed in the box body 2, and a battery is placed in the corner. A storage space 5 was used to store batteries 6, which were secured with cellophane tape or the like.

This had the same drawbacks as above.

The present invention has been devised in view of these points, and its contents will be explained below using illustrated examples.

Regarding the first embodiment (FIGS. 4 to 6), 20 is a synthetic resin housing having a clock mechanism (not shown) and a battery accommodating portion 22 for accommodating a dry battery 21. A locking hole 25 is formed on the lower side of one side wall surface 23 of the portion 22 for a holding tool 24 which also serves as battery insulation.

26 is a springable positive electrode plate having a bent part 29 provided inside the negative side wall surface 23, and 27 is a springable negative electrode plate having a bent part 30 provided inside the other side wall surface 28 of the battery accommodating portion 22. be.

The battery insulation/holding member 24 described above is made of synthetic resin and mainly includes a hanging insulating portion 31, a holding portion 32, and a locking portion 34 as a protrusion formed on a hanging arm 33.

The above-mentioned hanging insulating part 31 enters between the polar terminal 35 of the dry battery 21 and the bent part 29 of the positive electrode plate 26 and maintains an insulating state, and is also connected to the stepped holding part 32 and the locking part 34 of the hanging arm 33. This prevents the battery 21 from falling off.

36 is effective when removing the hook from the finger.

Next, the manner of use of the mechanism of the present invention will be explained.

The dry battery 21 is housed in the battery accommodating portion 22, and the battery insulating presser 24 is attached in the direction of arrow A.

At this time, the hanging insulating part 31 is inserted between the ■ polar terminal 35 of the battery 21 and the bent part 29 of the positive electrode plate 26 to break the electrical conduction, and the holding part 32 presses the top of the ■ polar terminal 35.

On the other hand, the locking portion 34 of the hanging arm 33 engages with the locking hole 25 in the one side wall surface 23 to prevent the dry battery 21 from coming off.

Next, when removing the battery insulation holding tool 24, use the hanging arm 33.
It is best to remove the locking portion 34 from the locking hole 25 while bending the portion in the direction of arrow B, and then extend the entire bow in the direction of arrow C.

Regarding the second embodiment (FIGS. 7 and 8) In this embodiment, the same parts as in the first embodiment are given the same numbers.

The feature of this embodiment is that the battery insulation holding tool 24 is
Although the specific structure is slightly different in that it is detachably attached to the negative electrode plate 27 side of the electrode plate 27, they are essentially the same.

37 is a top bent portion of the positive electrode plate 26. When attaching the battery insulator and presser 24, it is sufficient to insert it into the other side wall surface 28 from the direction of the arrow as shown in FIG.

At that time, the hanging insulating part 31 is inserted between the bent part 30 of the negative electrode plate 27 and the ○ pole surface 38 of the dry battery 21 to maintain insulation, and the dry battery 21 can be detached by the holding part 32 and the locking part 34. There isn't.

Next, when removing the battery insulation holding tool 24, the hook is at the part 36.
Just hook your finger on it and pull it upwards.

Since the present invention has the structure and function described above, it is possible to electrically insulate the dry cell battery and at the same time prevent it from falling off, and it is possible to conduct electricity simply by removing the battery insulation and holding device. There is no need to worry about inserting the wrong polarity, and there is no need for extra space in the packaging box when storing the product in the packaging box as with conventional products, making the whole package small. It has many practical benefits, such as being able to make it inexpensive and easy to install and remove without requiring any complicated work.
