Abstract

An auxiliary device that facilitates replacement of a button battery is provided. A dry battery and a wiring are housed in a hollow pipe. The coiled electromagnet 3 is fixedly disposed at the front end portion of the hollow pipe 5, and the push switch 8 is fixedly disposed at the rear end portion. The push button of the push-type switch 8 is pushed to excite the electromagnet 3, and the button battery is sucked to the magnetic pole 20 at the tip. When the push button of the push-type switch 8 is released, the electromagnet 3 is demagnetized, the button battery is separated from the magnetic pole 20, and the button battery can be stored in the intended battery storage location of an electronic device such as a hearing aid.

Description

In the present invention, a button battery is sucked by a magnetic force and is operated and stored in a battery case of an electronic device or the like.

With the downsizing of medical devices such as hearing aids, the button battery that is the power source of the medical device has been shortened along with the downsizing. On the other hand, there are many elderly people and persons with disabilities who use it, and the fact is that the small button batteries cannot be pinched well with their fingertips, and the batteries cannot be replaced.

The button battery size of electronic devices and medical devices is very small, and we have devised an auxiliary device that makes it easy to replace even those who are difficult to grasp with bare hands.

In the present invention, the button battery can be attracted and released by exciting and demagnetizing the electromagnet by the switch operation. The sucked button battery can be carried without dropping while the electromagnet is energized, and the button battery can be separated and stored in the intended place by demagnetizing the electromagnet on the battery case of electronic equipment. .

An elderly person or a handicapped person can easily store a button battery in an intended place without dropping the button battery.

A dry battery and wiring are housed in a hollow pipe, and a coil-type electromagnet is embedded at one end, and a push-type switch is embedded at the other end, and power is applied while the push-type switch is pressed. The magnetic force of the electromagnet is generated. When the switch is released, the magnetic force disappears.

An embodiment will be described below with reference to the drawings. A coiled electromagnet 3 in which an enameled wire 2 is wound around a nail (annealing) 1 is inserted and fixed in a resin lid 4, and this lid 4 is fixed to a tip of a hollow pipe 5 constituting a gripping portion with a vinyl tape 18 or the like. . The battery sleeve 6, the battery 14, and the wiring 7 are accommodated in the hollow pipe 5. The circuit is as shown in FIG. A resin lid 9 having a push-type switch 8 (a mechanical switch of a type that continues to be turned on while pressing the push button and turned off when the push button is released) attached to the rear end of the hollow pipe 6 is fixed with a vinyl tape 19 or the like.
The usage is described below. Hold the hollow pipe 5 with your hand and push the push switch 8 with your thumb. While the push-type switch 8 is being pressed, a magnetic force is generated in the planar magnetic pole 20 at the tip of the nail 1 so that the button battery 15 can be sucked and carried (state a in FIG. 4). When the push switch 8 is released, the button battery 15 loses its magnetic force and is separated from the magnetic pole 20 of the nail 1, and the button battery 15 can be dropped into the battery storage portion 17 of the electronic device 16 such as a hearing aid. (State of b in FIG. 4).

10 is a contact part of the + (plus) pole of the battery, and 12 is a contact of the-(minus) pole, and increases the contact pressure to the battery by the spring pressure. Reference numeral 11 denotes an insulating plastic for preventing the current from the positive electrode contact 10 from flowing into the nail 1, and 13 is a tray (thick paper) for preventing the spring 4 from hitting the wiring portion of the push switch 8. The battery sleeve 6 is a cushioning material that fills the gap between the pipe 5 and the battery 14. In order to prevent the positive electrode and the negative electrode of the button battery 15 from being short-circuited through the nail 1, the tip of the nail 1 can be coated with an insulating material such as paint. Further, the push switch 8 can be mounted on the side surface near the tip of the hollow pipe 5 instead of being mounted on the rear end of the hollow pipe 5. In this case, the push switch 8 can be operated with the index finger while holding the hollow pipe 5 in the shape of a writing instrument.
