DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a portable light.

[0002]

2. Description of the Related Art A portable light can be used by carrying a dry battery, a rechargeable battery or the like as a power source. In particular, a portable light powered by a rechargeable battery is economical because it can be used repeatedly by charging the battery, and a rechargeable battery such as a nickel cadmium battery has a more stable discharge characteristic than a dry battery. Therefore, there is a feature that the voltage does not decrease and the illuminance is kept constant even when used continuously for a long time.

A portable light powered by a rechargeable battery contains therein a rechargeable battery and a charging device for charging the rechargeable battery. The charging device includes a charging circuit such as a transformer or a rectifier circuit, and an AC plug blade for connecting to a commercial AC. The AC plug blade is provided so as to freely enter and exit the main body of the portable light.

When the portable light is used, the AC plug blade is retracted into the main body, so that the portable light is carried without any protrusion on the external appearance. On the other hand, when the rechargeable battery is charged, the AC plug blade is protruded. It is easy to plug into an outlet.

[0005]

However, although the AC plug blade is retracted into the main body, the tip of the plug blade is exposed from the outside, so that if dust or water enters from this portion, the charging circuit components and the like will be lost. May cause failure or short circuit. In addition, since the strength of the portable light body is not enough at the part exposed by the plug blade, if the portable light is accidentally dropped, the AC plug blade may be damaged and charging may not be possible. .
In particular, when the AC plug blade is provided at the rear end of the portable light, the rear end is likely to receive a large impact when dropped, and the AC plug blade may be further damaged. .

Accordingly, the present invention provides a charging battery A
To prevent dust and water from penetrating into the AC plug blade for a portable light equipped with a C plug blade, and to protect the AC plug blade even if the portable light is accidentally dropped. Provide a portable light that can be used.

[0007]

A portable electric lamp according to the present invention comprises:
A head portion having a light source, and a power supply rechargeable battery for the light source housed therein;
It has a cylindrical main body part provided with a C plug blade so that it can freely enter and exit, and a cap that covers the rear end of the main body part. The cap is integrally formed with an elastically deformable tongue piece, and the tongue piece is attached to the main body part. It is supported, and a cap is detachably attached to the rear end of the main body.

[0008]

Embodiments of the present invention will be described with reference to the drawings. The overall appearance of the portable light is constituted by the main body 1 and the head 2. The main body 1 is made of resin and is formed in a cylindrical shape, and houses therein four cylindrical nickel cadmium batteries connected in series with each other and a charging device for the nickel cadmium batteries.

Further, an AC plug blade 11 is provided at the rear end of the main body 1 so that the AC plug blade 11 can be freely moved in and out. The AC plug blade 11 can be switched to a projecting state in which the AC plug blade 11 projects perpendicularly to the main body 1. The protruding AC plug blade 11 is inserted into an outlet, and the nickel cadmium battery contained in the main body 1 is charged.

A power switch 13 slidable along the main body 1 is provided in front of the surface of the main body 1, and switches on / off the use of the portable light. The power switch 13 has a lock button 14. The lock button 14 is unlocked by being pushed in a direction orthogonal to the sliding direction of the power switch 13,
The power switch 13 can be operated.

A rubber cap 15 is provided at the rear end of the main body 1.
Is provided. The cap 15 is screwed to the main body 1 by a tongue piece 16, and can be put on or removed from the rear end of the main body 1 by the hinge action of the tongue piece 16.
Since the cap 15 is screwed to the main body 1, it is not lost even if it is removed. Further, the screwed portion is hardly seen by the tongue piece 16.

By covering the cap 15, the AC plug blade 11 can be covered, the plug blade 11 can be protected from impacts such as dropping, and water and dust can be prevented from entering. Prevent breakdowns and short circuits.

Further, the main body 1 has a hook 17. The hook 17 is made of metal and is screwed to the main body 1. In addition, the hook 17 is used for the assembly screw 1 of the main body 1.
8 so that the appearance of the main body 1 is neatly arranged. The hook 17 can be fixed to a chest pocket or the like of the outerwear as shown in FIG. As shown in FIG. 10, by bending the head 2 at 90 degrees, it is possible to irradiate the front without holding it by hand.

The head 2 has a bead ball 21, a reflecting mirror 22, and a lens 23. The bead ball 21 is connected to the nickel cadmium battery via the power switch 13 and is energized and turned on when the power switch 13 is turned on.

The head 2 can be swung within a range of 90 degrees around the fulcrum 24. The head part 2 can be swung at a middle position in addition to a position in a straight line with the main body part 1 and a position bent at a right angle. It can be used conveniently even in small spaces.

Further, a rubber ring 25 is mounted on the outer periphery of the head portion 2. The rubber ring 25 can protect the head unit 2 from an impact due to a drop or the like, and can prevent the portable light from rolling when the portable light itself is placed on a floor or the like.

Reference numeral 3 denotes an elastic band, which is made of a soft rubber such as polyester and is formed in a single band. The elastic band 3 can be wound around the main body 1,
After winding, the end can be detachably fixed by the button 31. Note that a magic tape or the like may be used instead of the button 31.

The elastic band 3 is shorter than the length of the main body 1. The elastic band 3 can be wound around the rear end of the main body 1 without covering the power switch 13. Therefore, the power switch 13 can be operated even when the elastic band 3 is wound. Further, the presence of the cap 15 provided at the rear end of the main body 1 prevents the main body 1 from falling off even when the elastic band 3 is wound.

Since the elastic band 3 is made of soft rubber, the elastic band 3 has a large frictional force with the palm when held in the hand, so that the elastic band 3 does not easily slip off from the hand.

The elastic band 3 is a shoulder belt 3
Two. The shoulder belt 32 is made of a material such as polypropylene that does not slide down when worn on the shoulder. The length of the shoulder belt 32 can be adjusted as shown in FIG.

[0021]

According to the present invention, the AC plug blade is provided at the rear end of the main body of the portable light, and the cap for covering this portion is provided. To prevent ingress of water and water.

Further, by providing the AC plug blade at the rear end of the portable light, it is easy to insert the portable light into an outlet, and it does not hinder the use of the portable light, so that it can be used conveniently. Furthermore, although the rear end of the portable light is most susceptible to impact when the portable light is accidentally dropped, it is protected by the cap and does not damage the AC plug blade. It is.

Further, since the cap is supported by the main body by the tongue piece, the cap can be easily attached to and detached from the main body, and even when the cap is removed, the cap is always supported by the main body and there is no fear of being lost. It is.
