Description

[Detailed Description of the Invention] The present invention relates to a battery holding device for fixing a battery used in an emergency lighting device or the like within a case which is a battery mounting portion.

Conventionally, in order to fix the battery in this type of device, the general method is to weld and fix the battery holding metal fitting to the case, and to fix the battery by sandwiching the battery holding plate to the battery holding metal fitting with a knob screw or the like.

In such a battery holding device, it is necessary to separately process a battery positioning part on the case for positioning the battery in the longitudinal direction, and this process is very time-consuming.
Furthermore, when attaching or detaching the battery, it is necessary to operate a knob screw, which has the disadvantage that it takes a relatively long time.

In order to solve the above-mentioned drawbacks, this invention enables battery positioning, installation, and removal with one touch, eliminates the need for processing the case, and allows batteries to be installed and removed in an extremely short time. The purpose is to obtain a holding device.

Hereinafter, an embodiment in which the present invention is applied to a device that holds two batteries will be described in detail with reference to the drawings.

In the figure, reference numeral 1 denotes a retaining spring made of elastic metal that is disposed on both end surfaces 13 of a battery 12, and leg portions 2 are formed at both ends so as to face outward from each other.

An L-shaped battery holding part 3 having a length slightly smaller than the outer diameter of the battery 12 is formed extending from these leg parts 2 and turned 90 degrees from the leg parts 2.

In addition, the bending angle θ between the battery holding part 3 and the leg part 2 is. is 90°
It is slightly smaller.

Further, the other ends of the battery holding portions 3 are integrally continuous with each other via a central portion 4 that curves toward the central portion of the battery 12.

Reference numeral 5 denotes a holding spring connector made of a wire rod, and at one end thereof there is a rotating part 6 wound with an inner diameter close to the wire diameter of the holding spring 1, in order to pass the one of the holding springs 1 through it. A retaining part 7 is integrally formed at the other end of the retaining spring 1, and the retaining part 7 has a vertically protruding convex part formed by winding a wire rod and engaging with the central part 4 of the one retaining spring 1. There is.

At the farthest end extending further from the engaging part 7, there is an operating part 8 which is 90' different from the above-mentioned retaining part 7 and rolled in horizontally.
is formed.

Reference numeral 9 denotes a battery mounting case that is attached to a lighting device (not shown), etc., and the battery mounting surface 10 has a long hole 11 in which the leg 2 of the retaining spring 1 is rotatably engaged, through which the battery 12 is mounted. The holes correspond to the length and are smaller than the spacing between the legs 2.

Next, a mounting method for fixing the battery in the above embodiment will be explained.

Insert the holding spring 1 into the long hole 11 of the battery mounting case 9 while squeezing the leg 2 of the holding spring 1 inward, and then attach the holding spring 1 to the case so that the inserted leg 2 always biases the spring force outward. Attach it to 9.

Next, one side of the holding spring 1 is pushed outward in the longitudinal direction of the case 9.

After placing the battery in the specified position, fold down the retaining spring 1.
Raise it back up and use the battery holder 3 to press the end face 13 of the battery 12.
At the same time, the retaining spring connector 5, which has been penetrated through the center part 4 of one of the retaining springs 1 in advance, hooks the retaining part 7 to the central part 4 of the other retaining spring 1, and the retaining springs 1 are held together. Inwardly pull the battery holding parts 3 together.
When the battery end face 13 is pressed, the battery 12 is fixed.

Further, when removing the battery, by pulling the operating portion 8 of the holding spring connector 5 upward, the retaining portion 7 can be easily removed, allowing easy battery replacement.

Note that if the bending angle θ° of the second leg of the holding spring 1 is made smaller than 90°, and the boundary 12 between the battery holding part 3 and the central part 4 is formed outside the vertical bisector of the battery 12, Even after the retaining spring coupler 5 and the retaining spring 1 are released from each other, the battery 12 can be maintained in a temporarily fixed state without rolling, which has the advantage of making it easier to replace the battery 12.

As explained above, according to the present invention, there is no need to separately process the battery positioning part as in the past, reducing the processing effort, and the battery installation or replacement work can be done with one-touch operation, making it extremely easy. A practically useful battery holding device can be obtained.
