Description

[Detailed description of the invention] The present invention relates to a battery mounting structure used in equipment that uses batteries, such as public telephones and vending machines, and is particularly aimed at facilitating the installation and removal of batteries into equipment. .

FIG. 1 shows a battery mounting structure conventionally used in public telephones, vending machines, etc.

In the figure, reference numeral 1 denotes a holder having a U-shaped cross section, and a battery 2 is housed inside this holder 1.
Further, this holder 1 is fixed to a side wall 4 by screws 3 at its upper and lower parts.

However, in such a conventional battery mounting structure,
When replacing the battery, it is necessary to remove and install the screw 3 each time, so there is a drawback that the work of attaching and detaching the battery 2 is troublesome.

In addition, if there are variations in the size of the batteries 2, especially if the batteries 2 are larger than the standard, the opening of the holder 1 may become too wide and the holes in the upper and lower parts of the holder 1 may overlap the holes in the side wall 4. There was also a drawback that the position did not match, and therefore it became impossible to attach the battery 2.

The purpose of the present invention has been made in view of the above-mentioned drawbacks, and includes forming a plurality of retaining pieces protruding from the upper and lower front edges of a holder that supports a battery, and elastically deforming an elastic member in the gap between the battery and the holder. This structure allows the holder to have elasticity by inserting the battery in the side wall, and utilizes this elasticity to engage the retaining piece with the retaining hole drilled in the side wall, making it easy to attach and detach the battery to the device. This provides a standardized battery mounting structure.

Hereinafter, details of the present invention will be explained using examples shown in the drawings.

FIGS. 2 and 3 a and 1) are an exploded perspective view, a side view, and a plan view showing an embodiment of the battery mounting structure according to the present invention.

In this embodiment, a pair of L-shaped retaining pieces 6 are integrally formed at the tips of the upper horizontal piece 51 and the lower horizontal piece 52 of the holder 5, which are formed into a substantially U-shaped cross section. Further, holding pieces 7 are bent at both sides of the lower horizontal piece 52 so as to rise upward.

Furthermore, 8 is a battery, and the upper and lower parts of this battery 8,
Upper horizontal piece 51 and lower horizontal piece 52 of the holder 5
Elastic members 9 made of a material such as foamed polyethylene are inserted in the gaps between the battery 8 and the battery 8 in an elastically deformed state, so that the upper and lower parts of the battery 8 are held between the elastic members 9. At the same time, due to the elasticity of the elastic member 9, the holder 5 is in a state where some ore is removed from the inside.

Note that the battery 8 is held by holding pieces 7 in the left-right direction.

On the other hand, the side wall 10 to which the holder 5 is attached has a plurality of L-shaped engagement holes 101 into which the engagement pieces 6 fit.

Now, to explain in more detail the shapes of the engagement piece 6 and the engagement hole 101, the retention piece 6 consists of an arm portion 6a and a bent portion 6b continuous to the arm portion 6a. is formed of a vertical hole 101a and a horizontal hole 101b continuous to the vertical hole 101a.

The width t1 of the vertical hole 101a is slightly larger than the width t2 of the arm portion 6a, and the width L1 in the longitudinal direction of the horizontal hole 101b is slightly larger than the width t2 of the arm portion 6a. The hole is slightly larger than the width dimension L2 in the direction.

Next, to explain the mounting operation of the battery mounting structure in the above configuration, first, the upper horizontal piece 51 and the lower horizontal piece 52 of the holder 5 are pressed to elastically deform the elastic member 9. The bent portion 6b is inserted into the horizontal hole 101b of each engagement hole 101.

After that, if the pressure on the holder 5 is released,
The elasticity of the elastic member 9 causes the holder 5 to be pressed from inside, whereby the arm portions 6a of each of the engagement pieces 6 engage with the vertical holes 101a of each of the engagement holes 101.
The holder 5 is supported by the side wall 10 as shown in FIGS. 3a and 3l).

On the other hand, when removing, press the upper horizontal piece 51 and the lower horizontal piece 52 of the holder 5 against the elasticity of the elastic member 9,
The holder 5 can be removed from the side wall 10 by pulling out the bent part 6b from the horizontal hole 101b while pushing down the arm part 6a to the position of the horizontal hole 101b where the engagement with the vertical hole 101a is released. be able to.

Note that the elastic member 9 is not limited to foamed polyethylene, and of course any elastic body that imparts elasticity to the holder 5 may be used.

As explained above, according to the present invention, the battery is attached by fitting a plurality of retaining pieces into correspondingly drilled retaining holes. There is no need for screw-fastening work as in the case of the above method, and therefore, it is extremely easy to attach and detach the battery to and from the device with just one touch.

Furthermore, since the holder is given elasticity by the elastic member interposed between the battery and the holder, the engagement piece and the engagement hole are reliably engaged, and therefore the battery is securely attached to the side wall. Installed.

Another practical effect is that even if there is variation in battery size, it can be absorbed by the deformation of the elastic member.
