Description

[Detailed description of the invention] This invention relates to a rechargeable portable light, in particular, a handle is rotatably supported on a light body that houses a light bulb and a secondary battery and has a charging plug protruding from the back. Therefore, the present invention relates to an improved structure in which the light bulb does not light up even when the slide switch is turned on or off when the charging plug is not covered, thereby ensuring that the secondary battery is reliably charged.

The applicant filed a patent application No. 55-64249 for this type of portable light.
(Japanese Unexamined Patent Publication No. 56-160701), the pivot shaft B of the handle A operates when the handle A covers the charging plug D protruding from the lamp body C. We have proposed a switch mechanism E that incorporates a switch mechanism E that does not operate when the handle A does not cover the plug D and the plug D is exposed for charging (see Figure 6). However, in this case, the switch mechanism E is entirely incorporated into the pivot shaft B, so the structure is complicated, and there is a risk that the assembly work efficiency will be deteriorated.

This project was created to improve this point.
The switch mechanism is simplified by providing a switch knob on the lamp body, and will be described below based on the embodiment shown in the drawings.

Reference numeral 1 denotes a generally flat cylindrical lamp body consisting of a cylindrical rear case 2 and a lens 3. Inside, a light bulb 4, a reflector 5, a secondary battery 6 and its charging mechanism 7 are housed, and a back A charging plug 8 connected to the charging mechanism is provided protruding from 2a.

Reference numeral 9 denotes an upper handle shaft support hole 2a and a lower handle shaft support hole 2 formed between the upper and lower surfaces of the lamp body 1.
an upper shaft support 10 and a lower shaft support 11 are respectively pivotally supported by the lamp body 1, and can take a first position located on the back side with respect to the lamp body 1 and a second position where the charging plug 8 is exposed. The handle 9 is a wide elastic resin handle that can be freely rotated from the left side of the lamp body 1 to the right side via the back side.
A plug cover 12 is rotatably provided to cover the charging plug 8.

13 is a resin switch base, and this base 13 is connected to the upper shaft support 10 by fitting a mounting plate 15 formed through the shaft portion 14 into a partial cutout 16 of the upper shaft support 10. installed, the handle 9
It is designed to rotate in conjunction with the

Furthermore, 17 is a slide switch, and in this switch 17, 18 is a slide switch knob having a hanging leg 18a, and 19 is a sliding hole 20 formed near the upper handle shaft support hole 2a on the side of the lamp body 1 to connect the hanging leg 18a. This is a slide switch mounting body in which the knob 18 is slidably mounted on the main body 1 by attaching the knob 18 through the main body 1.
A moderation pawl 19a that cooperates with the switch to move the mounting body 19 to the ON position or OFF position is provided to project laterally, and a switch contact piece 19b is provided to project downward.

22 is a switch contact piece made of an elastic band plate, and this contact piece 22 is connected to a rib 2 protruding from a separating plate 23 of the lamp body 1.
By inserting the base end 22a into the switch base 13, the intermediate abutting portion 22b can be freely moved toward and away from the switch abutting piece 19b, and the free end 22c is opposed to the circumferential surface of the switch base 13 so as to be movable toward and away from the switch base 13.

A first stepped portion 2 is formed on the circumferential surface of the switch base 13 and faces the free end 22c of the switch contact piece 22 when the handle 9 is rotated to the first position.
5 and a second step portion 26 facing the first step portion 25, and the metal contact plate 27 is attached to the first and second step portions 25, 26 with their flange pieces 27a, 2.
7b and attached to the switch base 13, the flange piece 27 is attached to the switch contact piece 22 only when the handle 9 is rotated to the first position.
A are attached so that they are facing each other.

Furthermore, 28 is a permanently sliding contact piece attached to the separating plate 23 like the switch contact piece 22, and its active end 28a is elastically biased so as to be in constant contact with the circumferential surface of the switch base 13.

Moreover, FIG. 5 is a circuit diagram.

Therefore, when the handle 9 is in the first position, when the slide switch 17 is turned on, the switch contact piece 19b is moved to the intermediate contact portion 22b of the switch contact piece 22.
The free end 22c is pressed against the switch base 13 by pressing the contact plate 27 on the free end 22c.
Since the flange pieces 27a of the switch contact pieces 2
When the handle 9 is in the second position, the switch contact piece 22 and the collar piece 27a of the contact plate 27 are not opposed to each other when the handle 9 is in the second position. Therefore, even if the slide switch 17 is turned on, the switch contact piece 22 and the permanent contact piece 2
8 is not conductive and the light bulb 4 does not light up.
Therefore, at this time, simply by inserting the charging plug 8 into an outlet in the room, the secondary battery 6 is charged regardless of whether the slide switch 17 is on or off.

The portable electric light of the present invention is constructed as described above, and includes, in particular, a lamp body that houses a light bulb and a secondary battery and has a charging plug protruding from the back side, a first position located on the back side with respect to the lamp body, and A handle having a pivot supported rotatably in a handle pivot hole of the lamp body so as to take a second position in which the charging plug is exposed; a switch base that rotates; a slide switch that is slidably mounted near the handle shaft support hole of the lamp body; and that presses the switch contact piece against the switch base when the switch is turned on; the handle is in the first position; Since the switch has a contact plate attached to the switch base so as to face the switch contact piece only when the switch is rotated, in other words, only the switch base with the contact plate can be attached to the shaft support of the handle. Since the sliding part of the slide switch is attached to the lamp body near the handle shaft support hole separately from the switch base, the structure is simple, and the switch mechanism can be completely integrated into the handle shaft. In comparison, assembly workability can be greatly simplified. Also, the handle is the second
When the switch is in the position, the contact plate on the switch base and the switch contact piece are not facing each other, so even if the slide switch is turned on, the light bulb will not be energized, and therefore the secondary battery will not be energized regardless of whether the slide switch is on or off. It can be charged and prevents charging errors. Furthermore, according to the present invention, the contact portion of the switch can be formed by bending an elastic band plate, so the structure of the parts used can be simplified and manufacturing costs can be reduced.
