JPS5919305Y2 - Battery mounting device for emergency lighting equipment - Google Patents

Description

[Detailed explanation of the idea] This invention relates to a battery mounting device for emergency lighting equipment.

As is well known, emergency lighting equipment must be equipped with a battery as a power source for lighting in an emergency, and the battery is normally required to be attached to the equipment body.

However, in the past, a holding metal fitting was prepared for this installation, and this was fixed to the main body of the instrument using screws or other means.

Therefore, each time the battery is replaced or inspected, it is necessary to loosen the screws and remove the holding metal fittings, and then tighten the screws to fix the holding metal fittings, which is extremely troublesome.

In addition, there is a risk that screws and the like may be lost in this case.

Normally, the batteries provided in this type of lighting equipment are required to be replaced periodically even when not in use, so they are replaced frequently.

This idea makes it easy to install and remove batteries.
Moreover, the purpose is to ensure that the mounting condition is secure.

An embodiment of this invention will be described with reference to the drawings. Reference numeral 1 indicates the main body of the emergency lighting equipment, 2 indicates a battery, and 3 indicates a spring piece.

The spring piece 3 of the embodiment shown in FIG. 2 uses a wire spring, which is formed into a U-shape, whose base end 4 is inserted into a hole provided in the instrument body 1, and rotated without a hinge. It is supported so that it can move freely.

A flat portion 6 and bent portions 7 are formed on both sides of the flat portion 6 at the intermediate portion between the distal end portion 5 and the proximal end portion 4.

Further, a window 8 is provided in the instrument body 1 so that the tip portion 5 can be inserted therethrough, and a hook piece 9 is formed on a part of the periphery of the window 8.

In the above configuration, the battery 2 is placed on the surface of the instrument main body 1, and the spring piece 3 is rotated around its base end 4 so as to straddle the surface.

Then, the tip portion 5 is inserted into the window 8, and here the tip portion 5 is hooked on the hooking piece 9.

In this state, the flat portion 6 elastically presses the surface of the battery 2, and the battery 2 is reliably pressed and fixed against the device main body 1.

Since the bent portion 7 is formed at this time, the unreasonable elasticity acting on the battery 2 is absorbed by the bent portion 7.

Therefore, the battery 2 can be held with appropriate elasticity.

To remove the battery once it is attached, it is best to push the tip 5 downward to remove it from the hooking piece 9 and then rotate it so as to pull up the spring piece 3.

FIG. 3 shows a configuration in which a leaf spring is used as the spring piece 3.

In this case, the tip of the leaf spring may be bent and the bent portion 5A may be hooked onto the hook piece 9.

Note that in each of the embodiments described above, the window 8 is not necessarily required; for example, a part of the instrument main body 1 may be cut and raised, and this may be used as the hook piece 9.

As detailed above, according to this invention, there is no need for conventional screws or other devices, and it is possible to simply use a spring piece, and moreover, it is only necessary to rotate this spring piece around its base end. Since the battery can be fixed or removed with the holder, the installation and removal operations are extremely simple.Furthermore, since it is installed elastically without unnecessary pressing force, the battery can be held securely without any damage. There is an effect like this.
