Description

[Detailed description of the invention] The present invention relates to light-emitting accessories such as tie clips, brooches, and pendants, which have a battery, 9 light-emitting diodes, and a switch, and which exhibit a great decorative effect by the light emitted from the light-emitting diodes. Regarding pins.

This type of jewelry has been proposed in the past, but the switch and battery parts are quite large, and small jewelry such as a tie clip is too ugly to be commercialized.

In particular, the structure of the switch section was relatively complex, which caused the increase in size.

In addition, the light emission starting voltage of the light emitting diode is 1.5 to 1.7■
In contrast, the voltage of mercury batteries and manganese dry batteries, which are widely known as conventional small batteries, is 1.3 to 1.5 ■.
For this reason, two or more batteries are required, and from this point of view as well, there has been a trend toward larger batteries.

This invention has a metal cylindrical lid that can be slid freely at one end of the cylindrical battery case that houses the battery, and by forming the switch part with this cylindrical lid, the overall size including the switch part can be reduced. This design was designed to make small accessories such as tie pins look less clumsy.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be explained below based on drawings showing a tie pin according to an embodiment thereof.

Figures 1 to 4 show one example of this, and 1 shows an electromotive force of 3.
A rod-shaped lithium-fluorocarbon battery (hereinafter referred to as a lithium battery) with a voltage of V or more, the lithium battery 1 has one pin-shaped terminal 1a serving as a cathode, and the other terminal 1b, which is part of the exterior case, serving as an anode. Become.

2 is a cylindrical metal battery case with both ends open.
An insulating ring 3 is attached to the inner surface of the opening side 2a.

Reference numeral 4 denotes a central core made of synthetic resin, with contact pieces 5, 5' located on both sides thereof, and the contact pieces 5, 5' fixed by press-fitting an outer core 6.

Among the contact pieces 5 and 5', the contact part 5a of one contact piece 5, which is insulated from the battery case 2, comes into elastic contact with the side surface of one terminal 1a, which is the cathode of the lithium battery 1, The contact portion 5a' of 5' is bent outward and attached to the battery case 2.
is in contact with the inner surface of the

In addition, the above-mentioned center core 4. The contact pieces 5, 5' and the outer core 6 are collectively referred to as a battery holder A.

Reference numeral 7 denotes a light emitting diode, which is connected to the contact pieces 5 and 5' through conductive wires 7 a and 7 b.

Further, the battery holder A is fitted into the other end opening side 2b of the battery case 2.

Reference numeral 8 denotes a metal cylinder having a bottom and having a notch 8a, and is fitted onto the other open end 2b of the battery case 2.

Further, the light emitting diode 7 is exposed to the front side through the notch 8a.

Reference numeral 9 denotes a decorative plate having a diamond cut or the like on its surface, and the light emitting diode 7 is exposed in the center.

Reference numeral 10 denotes a metal cylindrical lid that is fitted onto the outer surface of one end opening side 2a of the battery case 2 into which the lithium battery 1 is inserted. A spring 11 is inserted to be brought into contact with the other terminal 1b of 1.

Reference numeral 12 denotes a mount to be attached to a user's necktie, and the battery case 2 or the cylindrical body 8 is fixed to its pedestal 12a.

FIG. 5 shows a tie clip in another embodiment, 13
is a diffuser made of transparent or opaque jewelry, glass, resin, etc., and this diffuser 13 is placed in front of the light emitting diode 7.

The rest of the structure is the same as that of the previous embodiment.

The operation in the above configuration will be explained.

When the cylindrical lid 10 is inserted from the other terminal 1b side of the lithium battery into the outer surface of the one end opening side 2a of the battery case 2, the spring 1
1 contacts the other terminal 1b of the lithium battery 1 to close an electric circuit.

As a result, the other terminal 1b of the lithium battery 1 → the spring 11 →
Cylindrical lid 10 → battery case 2 → contact part 5a' → other contact piece 5' → conduction line 7b → light emitting diode 7 → conduction line 7a →
Since current flows from one contact piece 5 to the contact portion 5a to one terminal 1a of the lithium battery 1, the light emitting diode 7 emits light, producing a great decorative effect.

Furthermore, when the cylindrical lid 10 is slid outward from the open end 2a of the battery case 2, the spring 11 separates from the other terminal 1b of the lithium battery 1, thereby opening the electric circuit, and as a result, the light emitting diode 7 will no longer emit light.

In this case, even if the cylindrical lid 10 is completely removed, since the one terminal 1a of the lithium battery 1 is held in elastic contact with the side surface of the lithium battery 1 by the contact portion 5a of one of the contact pieces 5, there is no possibility that the lithium battery 1 will come off. It never happens.

In addition, although the tie pin was explained in the above embodiment, the battery case 2. A battery holder A is provided on a table part B constituted by a cylinder 8 and a cylindrical lid 10.

Since it houses a light emitting diode 7 and a lithium battery 1, by changing the attachment 12, it can be used as a brooch or pendant in addition to a tie pin, making it applicable to a wide range of uses.

Furthermore, as shown in FIG. 5, by providing a diffuser 13 in front of the light emitting diode 7, the light from the light emitting diode 7 can be increased, and by changing the shape of the diffuser 13, it can be used as an accessory according to one's taste. Can be used.

Further, since the lithium battery 1 having an electromotive force of 3V or more is used, the light emitting diode 7 can be made to emit light with one battery.

As described above, according to the present invention, there is provided a metal cylindrical lid that is slidably fitted to one end of the battery case and that connects and disconnects from the other terminal of the battery in the battery case, and the cylindrical lid Since the electric circuit is opened and closed by sliding the terminal into contact with and separating it from the other terminal of the battery, there is no need to provide a separate space for the switch as in the conventional case. The whole body including the parts can be made smaller, so even small accessories such as tie clips do not look ugly.

In addition, in the present invention, the battery case or the cylinder of the front metal part, which is composed of the battery case, the cylinder, and the cylindrical lid, is fixed to the base of the accessory mount, so the front metal part is fixed to the base of the accessory attachment. By changing the attachment, it can be used not only as a tie pin but also as a brooch or pendant.
In addition, since one lithium battery is used as the battery, it can be made smaller and lighter. Furthermore, one terminal of the lithium battery inserted in the battery case can be connected to one terminal connected to one end of the light emitting diode. The battery holder is elastically held with a contact piece, and the other contact piece connected to the other end of the light emitting diode is in contact with the inner surface of the battery case, so even if the metal cylindrical lid comes off, However, the lithium battery does not fall out, and the lithium battery can be securely held inside the battery case, and the electric circuit can be opened and closed by sliding the cylindrical lid as mentioned above. , by screwing the bottom cap,
Compared to those that open and close electric circuits, it is extremely easy to operate.
