Description

[Detailed description of the invention] <Technical field> The invention is mainly used for lighting in outdoor life such as camping, etc.
This invention relates to a portable lantern that uses candles as fuel, and more specifically, to a portable lantern that can be folded into a compact size while storing a candle.

<Background Art> Various proposals have been made for portable lanterns that use candles as fuel; for example, one that can be folded compactly while storing a candle is the one disclosed in Publication of Utility Model Publication No. 16607/1983. There is. However, in this conventional lantern, when the vessel holding the candle and the candle housing tube are folded into a compact size, they are engaged by a hanging ring, and when used, the hanging ring and the candle housing are engaged. The structure was such that the container was untied and only the case was pulled up, and then the container body and the candle housing tube were separated and the candle was ignited. Therefore, the candle body and the case must be separated each time the candle is ignited, and the candle must be re-stored in the housing cylinder after ignition. I hated that I couldn't do it.

<Disclosure of the invention> The present invention is an improvement on the conventional lantern described above, and not only can it be folded compactly while still housing the candle, but it can also be ignited easily and reliably, and can be extinguished with a single touch. The present invention aims to provide a portable lantern with a simple structure.

In the present invention, a candle holder that accommodates a candle in an upwardly biased manner is removably engaged with a bottom cylinder, and a cylindrical case is removably engaged with the bottom cylinder on the outside of the candle holder. , a transparent cylindrical body to which an upper cylinder having an openable and closable upper lid is attached is telescopically housed in the cylindrical case via a frictional engagement means, the upper lid has a ventilation hole near its outer periphery, and has a ventilation hole in its center. This portable lantern is formed by forming a flame-blocking surface that can extinguish the candle in close proximity to the igniting part of the candle when the transparent cylinder is housed in the cylindrical case.

As a means for biasing the candle upward with respect to the holder, preferably a helical spring is interposed between the candle bottom and the bottom cylinder. The frictional engagement means for holding the transparent cylinder at a desired extended position relative to the cylindrical case is preferably a plurality of elastic support pieces attached to the outside of the transparent cylinder.

BEST MODE FOR CARRYING OUT THE INVENTION The drawings show a preferred embodiment of the portable lantern according to the present invention. In FIG. 1 showing the structure of this embodiment, a transparent cylindrical body 2 made of heat-resistant transparent glass or the like is moved up and down in a cylindrical case 1 made of light metal such as aluminum through frictional engagement means.
In other words, it is accommodated in a flexible manner. As this frictional engagement means, in the illustrated example, three leaf spring-like elastic support pieces 3 are provided, each of which is hooked at both ends to the upper and lower open ends of the transparent cylinder 2, and the elastic support pieces 3 and the case are connected to each other. The transparent cylinder 2 can be held at a desired extended position by elastic frictional engagement with the inner surface of the transparent cylinder 2. Each elastic support piece 3
has an outward protruding part 3a on its upper part and an inward protruding part 3b on its lower part, and the outward protruding part 3a can be detachably engaged with the upper cylinder 12 described later, and The portion 3b can be elastically engaged with the edge portion 1a provided inside the upper end of the case 1, and when the transparent cylinder 2 is pulled up from the case 1, it can be removed by the lower bulge 3c of the inwardly protruding portion 3b. It seems like there is no such thing.

A cylindrical case 1 that accommodates a transparent cylinder 2 that can be expanded and contracted up and down has a window 4 with a vertically long hole through which the inside can be seen through, and a window 4 at the bottom that extends slightly inward. Three bent substantially L-shaped locking protrusions 5 are integrally protruded in the same direction at equal intervals, and the bottom cylinder 6
It is fitted into and locked into three U-shaped locking claws 7 spaced apart from each other on the inner surface.

The bottom cylinder 6, which is removably engaged with the cylindrical case 1, has a circular dish shape, and is connected to the lower end protrusion 9 of the candle holder 8 via the U-shaped locking claw 7. engaged. That is, although not shown in the drawings, a notch is formed in the protrusion 9 provided at the lower end of the candle holder 8 so as to correspond to the locking claw 7 of the bottom tube 6. The candle holder 8 can be engaged with the bottom cylinder 6 by aligning the notches and then rotating the candle holder 8 only slightly. Therefore, the locking claw 7 provided on the bottom tube 6 has the function of locking both the case 1 and the candle holder 8 independently.

The candle holder 8, which is detachably attached to the bottom tube 6, has a truncated bottomless bullet shape in the illustrated example to match the shape of the candle C, and one or more long holes 10 are formed on the side of the candle holder 8 at positions corresponding to the window portion 4 of the case 1 so that the amount of candle consumption can be seen from the outside.
The shape and structure of the holder 8 may be changed as appropriate as long as it can hold the candle properly. A spiral spring 11 is interposed between the candle C and the bottom tube 6, and as the candle shortens due to burning, the resilience of the spiral spring 11 presses the candle against the shoulder 8a of the holder 8.
Reference numeral b denotes an annular projection provided at the upper end of the candle holder, which serves to prevent part of the melted wax from dripping outside the holder 8.

An upper cylinder 12 is attached to the upper part of the transparent cylinder 2 via an outward protrusion 3a provided at the upper part of the elastic support piece 3. That is, the outward protrusion 3a is connected to the upper cylinder 12.
The transparent cylinder body 2 and the upper cylinder 12 are connected by fitting into the engagement hole 13 provided on the side surface of the transparent cylinder body 2, and the upper cylinder body 12 can be expanded and contracted with respect to the case 1 as a unit. Further, the upper cylinder 12 has an upper lid 15 which can be opened and closed via a hinge 14, and is stopped and connected by a conventional stopper 16. The upper lid 15 has a plurality of holes drilled near its outer periphery to serve as ventilation holes 17, and has a hanging ring 19 in the center to prevent it from getting hot when held, and the transparent cylindrical body 2 is pushed in and stored in the cylindrical case 1. The flame shielding surface 18 is close to the igniting part of the candle and can extinguish the flame when the candle is lit.

From the above description, it seems that the action of the lanthanum according to the present invention has become clear, but an example of how to use it will be briefly explained as follows.

A candle C is housed in a candle holder 8, and a spiral spring 11 is interposed between the candle bottom and the bottom tube 6 to engage the holder 8 with the bottom tube 6. In this state, the candle C is urged upward by the elastic force of the helical spring 11 and is held in contact with the shoulder portion 8a of the holder 8. Next, the transparent cylinder 2 to which the upper cylinder 12 is attached is stored in the case 1 in advance, and the case 1 is engaged with the bottom cylinder 6.

When using the lantern assembled in this way, the transparent cylindrical body 2 is stored in the case 1 in advance as shown in FIG.
If the candle C is opened, the ignition part of the candle C is located near the opening of the upper cylinder 12, so that it can be easily ignited. When the ignition is completed, the upper cylinder 12 and the transparent cylinder 2 are pulled up together from the case 1 and the upper lid 15 is closed, resulting in the state shown in FIG. 3. When it is desired to extinguish a fire, the upper cylinder 12 and the transparent cylinder 2 are pushed down together and housed in the case, and as a result, the flame shielding surface 18 of the upper cover 5 approaches the flame and can extinguish the flame.

Since the lantern of the present invention has the above-mentioned structure, it can be folded into a compact size with a single touch operation while still housing the candle, and the ignition operation can be easily and reliably performed by simply opening the top cover. It is a useful lantern that can be easily folded and extinguished with a single touch.
