Description

[Detailed explanation of the idea] This invention relates to the improvement of fluorescent lanterns.

Conventional fluorescent lanterns are broadly divided into those in which rod-shaped fluorescent tubes are held in parallel on the front of a battery case, and those in which the battery case holds the fluorescent tubes in series. It is effective when the light from the light tube is concentrated in only one direction, but it is not suitable when the light is irradiated over a wide range, and the latter has the opposite function. There is.

For this reason, one fluorescent lantern cannot be used selectively for both modes of use, making it difficult to use.

This idea was made in view of the above circumstances, and by collapsably connecting the fluorescent illumination unit structure to a battery case with a reflective surface formed on the outer wall, one fluorescent lantern can provide unidirectional irradiation and full illumination. The object of the present invention is to provide a simple fluorescent lantern that can be used for both directional irradiation and directional irradiation.

An embodiment of this invention will be described below with reference to the drawings.

In Fig. 1, 1 is a cylindrical battery case, and inside it is
Housed therein are power batteries 2, 2, a wiring board 4 on which elements 3 for configuring a fluorescent tube lighting circuit are set, and the like.

5 is a fluorescent tube driven by the lighting circuit, and 6 is a transparent cylindrical hood that surrounds the entire circumference of the fluorescent tube 5. This hood 6 also serves as a protective case for the fluorescent tube 5. , a part or the whole may be colored if necessary.

Reference numerals 7 and 8 are caps fixed to the upper and lower portions of the hood 6, respectively, and the fluorescent tube 5, the hood 6, the caps 7 and 8, and the like constitute a fluorescent illumination section structure 9.

10 is a socket fixed to the lower cap 8, 11 is a stay erected on the lower cap 8, and 12 is a stay 1.
It is a socket fixed at the tip of 1, and both sockets)
The fluorescent tube 5 is inserted and held between the caps 10 and 12, and is turned on by turning on a power switch 13 formed on the outer wall of the lower cap 8, for example.

14 is a handle portion formed on the upper cap 7, and 15 is a stand member attached to the battery case 1 side.

The battery case 1 side and the lighting section structure 9 side are connected and held by a connecting mechanism 20 shown in FIG. 2.

This coupling mechanism 20 is made of, for example, a well-known link hinge.

That is, the connection mechanism 20 connects the frame 21 fixed to the battery case 1 side, the frame 22 fixed to the fluorescent lighting unit structure 9 side, and the frames 21 and 22. Do 1
Consisting of a pair of bell cranks 23, 24, both bell cranks 23, 24 are rotatably supported in the middle 25, and each end 23a, 24a is also pivoted to each of the mating frames 22, 21, respectively. and each other end 23b.

The pins 26,27 provided on the respective frames 21,22 are also slidably held in grooves 28,29 formed in the respective frames 21,22, thereby acting as hinges, as shown in FIG. It is designed to be foldable.

That is, the connection mechanism 20 connects and holds the illumination unit tank 9 side to the battery case 1 in a foldable manner.

If the sliding resistance of the bell cranks 21 and 22 in the connection mechanism 20 is set to be large, the lighting section body 9 can be held in any folded position.

Reference numeral 16 denotes a reflective surface formed on the outer wall surface of the battery case 1, and this reflective surface 16 directs the light from the fluorescent tube 5 forward and focuses it in a specific direction at the folded position of the illumination tank body 9. The lantern emits light, and in this embodiment, it is constructed with four curved faces, and the outer diameter of the lantern in the folded state of the illumination tank body 9 is made as small as possible.

Of course, the reflective surface 16 may be constructed as a flat surface as shown in FIGS. 4 and 5.

This reflective surface 16 is formed by resin-plating the synthetic resin battery case 1 with a shiny metal such as chrome, but it may also have a structure in which thin aluminum plates or thin stainless steel plates are attached only to the four face portions, or It may also be formed by inserting a separate reflector into the battery case 1.

In the above configuration, when the illumination tank body 9 is used in an extended state with respect to the battery case 1 as shown in FIG. It is possible to illuminate a wide area by irradiating the light outward from the battery case 1. Also, if the illumination unit tank 9 is used in a folded state with respect to the battery case 1 as shown in FIG. The surface 16 allows the light from the fluorescent tube 5 to be concentrated in only one direction, and in this state it is compact and convenient for carrying.

In particular, when carrying the battery case 1, the reflective surface 16 of the battery case 1 is protected by the lighting tank body 9, which prevents twigs, sand, etc. from hitting the reflective surface 16 and damaging the reflective surface 16 and causing fogging. be able to.

Further, in this embodiment, the connecting mechanism 20 is configured with a ring hinge, and when the lighting section body 9 is extended with respect to the battery case 1, the connecting mechanism 20 is not exposed to the outside.
There is an advantage that the battery case 1 and the lighting unit tank body 9 are in close contact with each other and the holding state is stabilized.

Of course, the connection mechanism 20 is not limited to the link hinge, and other means may be used as appropriate.

As described above, this invention connects the fluorescent illumination tank to the battery case 1 in a foldable manner, and provides a reflective surface that irradiates light from the fluorescent tube in one direction when the illumination tank is folded. By forming it on the outer wall of the battery case, it is possible to arbitrarily select and set the mode in which the light from the fluorescent tube is irradiated in a golden color in all directions, and the mode in which it is irradiated only in one direction. Furthermore, by folding the fluorescent illumination unit tank body into a battery case, it is possible to provide a fluorescent lantern that can be easily carried.
