【Example】

Embodiments of the present invention will be described in detail below using a rechargeable light based on the drawings.

[0007] 1 is a rechargeable light, and is equipped with a lens 2, a reflector 3, and a miniature light bulb 4 on the front. Ru. Furthermore, two cylindrical parts 5 and 6 are formed at the rear of the rechargeable light 1. cylindrical part 5 is provided with a switch 7, and the switch 7 is operated by holding this cylindrical portion 5 with your hand. It is now possible to create Additionally, hooks 8 are formed at the front and rear ends of the cylindrical portion 5. You can also hang it on your shoulder or hang it on the wall by passing it through a belt if necessary. difference Furthermore, a spare miniature light bulb 4' is provided within the cylindrical portion 5. On the other hand, the cylindrical part 6 has a cylindrical shape. The battery pack 9 is detachably inserted. In other words, the battery pack The battery pack 9 has a rear end formed with an engaging portion 10 that engages with the cylindrical portion 6. After inserting it into section 6, rotate it about 90 degrees to attach battery pack 9. The sea urchin is turning. When the battery pack 9 is attached, the contacts provided in the cylindrical part 6 11 contacts the output contact of the battery pack, which will be described later, and connects the battery pack 9 and the small light bulb. 4 are electrically connected via the switch 7.

[0008] Now, inside the main body case 12 of the battery pack 9, there are a plurality of Ni-Cd batteries 13, A charging device consisting of a transformer 14 and other charging elements, and a charging device connected to the charging device It is equipped with a contact 15 and an output contact 16 that is connected to the Ni-Cd battery 12 and takes out the DC output. It is being In addition, outside the main case 12, there is a commercial The AC plug 17 and the slider that restricts and releases the rotation of the plug 17. It is equipped with 18 dot knobs.

[0009] The plug 17 has a pair of plug blades 19 and a plug base in which the plug blades 19 are embedded. It is more than 20. In addition, the slide knob 18 is And when storing, hold the end of the plug base 20 and rotate the plug 17. A pair of ribs 21 and 22 are integrally molded. This pair of ribs 21 and 22 are thin. They are connected to each other by a flesh plate-like flexible portion 23. Furthermore, slide knob 18 is It is always biased in one direction by the spring 24, and the knob 18 is pushed in the other direction against the spring force. When the rib 21 is slid in the direction, the rib 21 moves in conjunction with the slide movement of the knob 18. At the same time as it moves up and down, the rib 22 tilts due to the bending of the flexible portion 23. Ru.

0010 Here, the rotating operation of the insertion plug 17 will be explained based on FIGS. 3 and 4. 3a and 4a show the plug 17 in a protruding position. At this time, plastic The end of the plug base 20 abuts the rib 21 upright, and the biasing force of the coil spring 24 holds the end of the plug base 20 and the rib 21 in contact with each other, so the plug 17 cannot be rotated. The protruding posture is locked without being able to do so. Further, the proximal end of the plug blade 19 is It is designed to make contact with the contact point 15, and when the plug blade 19 is connected to a commercial alternating current, Ni- Charging of the CD battery 12 is started.

[0011] Next, slide the slide knob 18 downward against the biasing force of the coil spring 24. (FIG. 3b), the rib 21 moves downward with the knob 17. At this time The rib 21 no longer comes into contact with the proximal end of the plug blade 19, and the lock of the insertion plug 17 The lock is released. As a result, the plug 17 becomes rotatable and the plug blade 19 can be rotated. When the plug 17 is turned, the plug 17 begins to rotate (Fig. 4b). In addition, the slide knob 18 is When the ride operating force is removed, it returns to its original position due to the biasing force of the coil spring 24.

0012 After that, when the plug 17 is rotated 90 degrees, the base end of the plug blade 19 is connected to the other rib. Since the plug 17 abuts perpendicularly to the plug 22, the plug 17 cannot rotate in the protruding direction. As a result, the storage position is locked. At this time, the proximal end of the plug blade 19 is It comes into contact with the force contact 16 (FIGS. 3c and 4c). Here, the battery When the plug 9 is inserted into the cylindrical part 6 of the rechargeable light 1, the plug blade 19 is inserted into the cylindrical part 6. By touching the contact point 11 and turning on the switch 7, the miniature light bulb 4 lights up. . Furthermore, to unlock the storage position of the plug 17, insert the battery pack 9 into the After pulling it out from the cylindrical part 6, slide the slide knob 18 downward. , the flexible portion 23 bends and the rib 22 tilts accordingly. Therefore, rib 22 is no longer in contact with the base end of the plug blade 19, and the insertion plug 17 is unlocked. removed. As a result, the plug 17 can be rotated again (FIG. 4b).

[0013] By the way, this battery pack 9, when the plug 17 is stored, That is, with the plug blade 19 in contact with the output contact 16, the plug blade 19 accidentally To prevent the plug blade 19 from being inserted into a garden outlet, the tip of the plug blade 19 should be attached to the slide knob. It is designed to retreat sufficiently inward of 18.
