Description

[Detailed Description of the Invention] This invention relates to a rechargeable portable electric light that also functions as a standing light that turns on during a power outage.

In Japanese Patent Application No. 55-64249, the applicant has published figures 1 to 4.
As shown in the figure, a bundle 5 is attached to a lamp body 4 which houses a light bulb 1 and a secondary battery 2 and has a charging plug 3 protruding from the back side.The bundle 5 is placed in a first position where the bundle 5 is located on the back side with respect to the lamp body 4. (See Figure 1) and a second position where the charging plug 3 is exposed (See Figure 2). The patent application is for a portable electric light provided with a switch means 6 consisting of a slide switch for switching between the OFF and OFF positions.

The switch means 6 is integrated with a switch knob 7 and has a switch sliding piece 8 that rotates as the bundle 5 rotates.
and a switch board 9 fixed on the side of the lamp body 4. When the bundle 5 is in the first position and the switch knob 7 is slid to the on position (ON) or the off position (OFF), the fourth position is set. As shown in FIG. 1A, a pair of contact portions 8ay8a of the switch sliding piece 8 come into contact with and separate from a large-diameter arc-shaped contact surface 9a and a small-diameter arc-shaped contact surface 9a to turn on or extinguish the light bulb 1.

Further, when the bundle 3 is in the second position, the switch sliding piece 8 rotates with respect to the switch board 9, and the pair of contact portions 8a, 8 of the switch sliding piece 8 rotates as shown in the opening of FIG.
a enters the pair of gaps 10 and 10, therefore, even when the switch sliding piece 8 is slid to the lighting position (ON) by the switch knob 7, the switch sliding piece 8 remains in the large-diameter arc-shaped contact surface. 9a and the small-diameter arc-shaped contact surface 9b, the light bulb 1 is kept in an unlit state.

There is no problem with the switch means 6 having such a configuration if it is a simple rechargeable portable electric light, but when providing the function of a standing light (power outage light), the switch means 6 is installed between the secondary battery 2 and the light bulb 1. Because of the presence of the light bulb 1, it was impossible to turn on the light bulb 1 during a power outage with the current structure.

Keeping in mind that this proposal is rejected, the purpose is to provide a standing light function to the rechargeable portable electric lamp with the above structure.

The basic structure of this project is to store a light bulb and a secondary battery in a lamp body with a charging plug protruding from the back, and to place the bundle in a first position where the bundle is located on the back side of the lamp body and the charging plug is exposed. It is rotatably supported so as to be able to assume a second position, and is comprised of a switch sliding piece that rotates as the bundle rotates, and a fixed switch board that the sliding piece slides into contact with, and that can be set to a light-on position and a light-off position. In the device provided with a first switch means for switching, the second switch means is turned off when the commercial power is energized and turned on at the time of power outage, the first switch means, the light bulb, and the secondary battery are connected in series, and the switch board of the first switch means is connected in series. The contact surface is configured to be turned ON when the lindle is in the second position, regardless of whether it is in the lighted position or the lighted out position.

With this configuration, when the bundle is rotated to the second position, the first switch means is always turned on, and when the charging plug is connected to a power outlet, charging is always performed regardless of the switching position of the first switch means, and in the event of a power outage. The light bulb is turned on.

In addition, since it is only necessary to change the shape of the contact surface of the switch board of the first switch means, a standing light function can be provided extremely easily and inexpensively, and there is no need to switch the first switch means each time during charging, improving operability. Demonstrates the effect of

An embodiment of the present invention will be described with reference to FIGS. 5 and 6.

Note that the only difference from the conventional example shown in FIGS. 1 to 4 is the configuration of the switch means 61 and the electric control circuit, and the others are substantially the same, so a description thereof will be omitted.

That is, in the switch means 61, the switch sliding piece 8 remains the same, but as shown in FIG.
Both ends of the bundle 1b are extended upward, and the circuit is closed in either the lit position or the unlit position when the bundle 3 is in the second position shown in the opening of the figure.

Next, the electric circuit will be explained according to FIG.

11 is a step-down transformer connected to the charging plug 3, 12 is a rectifier diode, 14 is a smoothing capacitor, 15 is a resistor,
A diode 16 is connected in series with a light bulb 1, a secondary battery 2, a switch 61, and a switch 17 consisting of an NPN transistor. A current flows between the battery 2 and the diode 16, which is reverse biased due to the voltage drop of the diode 16 and turns off. During a power outage, a current flows through the circuit consisting of the secondary battery 2, the resistor 15, the base/emitter switch means 61 of the switch means 17, and the secondary battery 2. flows and turns on.

In the above embodiment structure, when the switch means 61 has the bundle 3 in the first position when used as a portable electric light, the relationship between the switch sliding piece 8 and the switch board 91 is in the fifth position.
When the switch means 61 is set to the lighting position as shown in FIG.

When set to the off position, it slides as shown by the solid line to turn off the 0FFL light bulb 1.

Next, when the bundle 3 is in the second position, the switch means 61
As shown in Figure 5, it is in the ON state in both the lit position (shown by broken lines) and the off position (shown by solid lines), and when the commercial power is turned on, the switch means 17 is turned OFF to charge the secondary battery 2 and turn off the light bulb 1. However, in the event of a power outage, switch means 17 is turned ON.
The light bulb 1 is turned on by the secondary battery 2.
