Description

  The present invention relates to a lantern.

Although lanterns are rarely used on a daily basis as lighting fixtures, they are still valuable in special situations.
For example, lanterns are still widely used in ancient Japanese festivals and religious events such as the Bon Festival. In many cases, lanterns are used as decorations or landmarks at izakaya stores.

There are various types of lanterns, but the basic structure of a typical one is as follows.
The paper lantern has a fire bag (paper lantern body), and an upper ring and a lower ring provided above and below it.
The fire bag has a cylindrical shape, is mainly formed of paper, and is supported by a number of annular or spiral bone rings such as bamboo straws.
Thus, the lantern (firebag) can be expanded and contracted in a bellows shape. In other words, the lantern can be displaced between the original extended state and the compressed state.
The lantern is stored in an expanded state when it is used, and in a compressed state when it is not used. The compressed state is a broad concept.

  Originally, in the compressed state, the lower edge of the upper ring is positioned slightly higher than the upper edge of the lower ring, and a flame bag (its lower edge) is interposed between the two in the height direction. (Neighborhood) is sandwiched.

  By the way, in general, the upper ring has a slightly larger diameter than the lower ring. Precisely, the inner diameter of the upper ring is slightly larger than the outer diameter of the lower ring.

For this reason, when the lantern is handled in a messy manner and is compressed too much in the vertical direction, the lower ring may be partially or fully fitted in the upper ring in the height direction. There is (this state is called an overcompressed state).
In the over-compressed state, the lower edge of the upper ring is positioned lower than the upper edge of the lower ring, and in that case, as described above, the fire bag that is sandwiched between the two A shearing force acts in the vicinity of the lower edge portion of the sheet, and the portion is damaged.
In this way, even if the lantern (firebag) is not damaged, the lantern (firebag) is in an unusable state because only that portion is damaged. This is very uneconomical.

  In particular, in the case of festivals, a large amount of lanterns are often used, and when a large amount of lanterns are cleared after the festival ends, they are often handled in a messy manner. In addition, when a large amount of compressed lanterns are stored one above the other, an excessive force may be applied in the vertical direction. In this way, the lantern becomes overcompressed and the vicinity of the lower edge of the sack is damaged.

In addition, in order to prevent the above, the fire bag is compressed with the cardboard placed on the lower ring, and in the compressed state, the cardboard is placed between the lower ring and the upper ring in the height direction. It is also assumed that it is inserted.
However, the work is complicated, and it becomes remarkable when dealing with a large amount of lanterns like a festival.

  An example of prior art in this field is disclosed in Patent Document 1.

[Example 1]
Next, the lantern of Example 1 of this invention is demonstrated based on FIGS. 1-6C.
As shown in FIGS. 1 to 4A, this lantern has a fire bag (lantern body) 10, an upper ring 20, and a lower ring 30.

As shown in FIG. 1 and FIG. 2, the fire bag 10 has a cylindrical shape in which paper such as Japanese paper or a synthetic resin film is attached to a large number of annular or spiral bone rings 15 made of bamboo or the like. Is formed. In this way, the fire bag 10 is supported by the bone ring 15. In addition, in drawing (except FIG. 5), it describes in the shape of a single thing which does not have thickness simply.
As shown in FIG. 4A, FIG. 4B, etc., the paper lantern (firebag 10) can be expanded and contracted in a bellows shape. In other words, the lantern can be displaced between the original extended state (FIG. 4A and the like) and the compressed state (FIG. 4B).

As shown in FIG. 1 to FIG. 5, in this lantern, the fire bag 10 has a concentric circular cross section at any height position. That is, it has a so-called rotating body shape with the central axis as a reference.
And the fire bag 10 (extension state) has a substantially spherical shape having openings (reference numerals omitted) above and below, and the center height position has the largest diameter (the portion is referred to as “maximum diameter portion”). I will say). That is, the fire bag 10 suddenly becomes larger in diameter from its upper edge toward the lower side, and also becomes larger in diameter from its lower edge toward the upper side. It has a curved vertical section.
The shape of the fire bag 10 is not limited to this, and various shapes can be applied. For example, the maximum diameter portion may extend long in the vertical direction in the vicinity of the center in the height direction.

As shown in FIGS. 1 to 4A, the upper ring 20 has a non-covered annular shape (flat cylindrical shape), and as shown in FIGS. 2 to 4A, all of them are wooden annular shapes (flat shapes). It has a cylindrical inner upper ring 21 and an upper outer ring 22 (both are open).
As shown in FIG.2 and FIG.3, the upper part of the fire bag 10 is the upper adherend part 12, and the upper adherend part 12 is stuck to the upper inner ring 21 (the outer peripheral surface). On the other hand, the upper outer ring 22 is fitted and fixed by a nail or the like.
Thus, as shown in FIGS. 1 and 4, the upper ring 20 is formed, and the upper ring 20 is concentrically coupled to the fire bag 10.

As shown in FIGS. 2 to 4A, the lower ring 30 has a bottomed annular shape (flat bottomed cylindrical shape), both of which are a wooden annular shape (flat cylindrical shape) of the lower inner ring 31 and the lower side. It has an outer ring 32. The lower inner ring 31 is bottomless, while the lower outer ring 32 is bottomed.
As shown in FIG.2 and FIG.3, the lower part of the fire bag 10 is the lower adherence part 13, and the lower adherence part 13 is stuck to the lower inner ring 31 (its outer peripheral surface). On the other hand, the lower outer ring 32 is fitted and fixed by a nail or the like.
Thus, as shown in FIGS. 1 and 4, the lower ring 30 is formed, and the lower ring 30 is concentrically coupled to the fire bag 10.

  In addition, although the upper to-be-adhered part 12 and the lower to-be-adhered part 13 of the firebag 10 are illustrated in FIG. 3, since they are very thin, they are abbreviate | omitted in the other figure.

As shown in FIGS. 1 to 4A, the upper ring 20 is provided with a hanging portion 25.
As described above with reference to FIGS. 2 to 4A, the lower ring 30 (lower outer ring 32) has a bottomed shape, and a candle stand 35 is formed on the bottom 34 of the lower ring 30 (lower outer ring 32). Is provided.

  As described above, the firing bag 10 has a rotating body shape, and the annular upper ring 20 and the lower ring 30 are concentric with the firing bag 10 as described above. For this reason, as shown in FIG. 5, the lanterns (upper ring 20, chimney 10, lower ring 30) as a whole have a rotating body with reference to the central axis, and the upper ring 20 and the lower ring 30 are mutually connected. Concentric.

  As shown in FIGS. 4A to 5, the upper ring 20 has a slightly larger diameter than the lower ring 30. Strictly speaking, the inner diameter of the upper ring 20 (upper inner ring 21) is slightly larger than the outer diameter of the lower ring 30 (lower outer ring 32).

  As shown in FIGS. 1, 2, and 5, a plurality of (for example, three) upper attachment members 50 are attached to the upper ring 20. The three upper mounting members 50 are fixed to the upper ring 20 at equiangular intervals.

As shown in FIGS. 2 and 6A to 6C, each upper mounting member 50 is formed by bending one wire. That is, one wire is bent by 180 degrees with respect to the vicinity of the center thereof to be substantially U-shaped, and is further bent substantially vertically.
Thus, each upper mounting member 50 has a pair of upper legs 52 and an upper inner protrusion 55.
That is, the pair of upper leg portions 52 extend substantially parallel to each other. The upper inner projecting portion 55 has a gentle V shape (or U shape), and extends vertically from the pair of upper leg portions 52.
Of the pair of upper legs 52, one upper leg 52a is long and the other upper leg 52b is short.

As shown in FIGS. 3 to 5, each upper mounting member 50 has a pair of upper leg portions 52 forced from the lower side with respect to a portion between the upper inner ring 21 and the upper outer ring 22. And is bonded to the upper inner ring 21 and the upper outer ring 22 with an adhesive as necessary, and is fixed to the upper ring 20.
In this way, the pair of upper legs 52 are built in the upper ring 20, and the upper inner protrusion 55 protrudes substantially horizontally inside the upper ring 20 (on the side of the center axis of the lantern). This upper inner protrusion 55 corresponds to the “fitting prevention portion” of the present invention.
And the front-end | tip part (part located in the innermost part of the upper ring 20) of the upper inner protrusion part 55 is located inside (the center axis line side of a lantern) rather than the lower ring 30 (the inner edge part). That is, the tip of the upper inner protrusion 55 is inside the outer edge of the lower ring 30 and further inside the inner edge of the lower ring 30.

Next, the effect of this lantern will be described.
When this lantern is used, the upper ring 20 and the lower ring 30 are separated from each other as shown in FIGS. 1 and 4A.
On the other hand, when the use of the lantern is ended and stored, as shown in FIG. 4B, the upper ring 20 and the lower ring 30 are brought into a compressed state. Note that this compressed state (FIG. 4B) is the most compressed state in the compressed state (not including the over-compressed state).

As shown in FIGS. 4B and 5, in the compressed state, the upper inner protrusion 55 abuts against the lower ring 30 (the upper edge). To be precise, the abutment is indirectly in contact with the lower edge portion of the sack 10. Thus, the upper ring 20 is prevented from further descending (fitting into the lower ring 30).
In this way, in this lantern, it is effectively prevented from being over-compressed, and the vicinity of the lower edge of the fire bag 10 is prevented from being damaged.

In addition, this lantern provides the following effects.
As described above with reference to FIGS. 6A to 6C and the like, of the pair of upper legs 52 of each upper mounting member 50, one upper leg 52a is long and the other upper leg 52b is short. For this reason, each upper attachment member 50 is attached to the upper ring 20 as follows.
First, as shown in FIGS. 6A to 6B, only the longer upper leg 52a is attached to the upper ring 20 (between the upper inner ring 21 and the upper outer ring 22), and thereafter, FIG. 6B to FIG. 6C. As shown, the shorter upper leg 52b is attached.
For this reason, the upper attachment member 50 can be easily attached to the upper ring 20.

That is, if the lengths of both upper legs 52 are the same, both upper legs 52 are attached simultaneously or substantially simultaneously. In this case, both the upper legs 52 need to be positioned and attached at a predetermined position (between the upper inner ring 21 and the upper outer ring 22) simultaneously or substantially simultaneously.
However, since the length of the two upper leg portions 52 (52a, 52b) is different in the upper mounting member 50, the upper leg portions 52a, 52b are positioned and attached one by one as described above. For this reason, the upper attachment member 50 can be easily attached.

[Example 2]
Next, the lantern of Example 2 of the present invention will be described based on FIGS. 7 to 8B with a focus on differences from Example 1. FIG. The elements common to the first embodiment are denoted by the same reference numerals, and the description thereof is omitted as appropriate (the same applies hereinafter).

This lantern has a plurality of (for example, three) lower mounting members 60 instead of the plurality of upper mounting members 50 in the first embodiment.
Each lower mounting member 60 is formed by bending one wire, like the upper mounting member 50, and has a pair of lower leg portions 62 and a lower outer protrusion 65.
The pair of lower legs 62 extends substantially parallel to each other. The lower outer protrusion 65 has a gentle V shape (or U shape) and sandwiches an obtuse angle with the pair of lower legs 62.

Each of the lower mounting members 60 includes a pair of lower legs 62 that are forcibly inserted from above into a portion between the lower inner ring 31 and the lower outer ring 32, and as required. It is bonded to the lower inner ring 31 and the lower outer ring 32 with an adhesive, and is fixed to the lower ring 30.
In this way, the pair of lower legs 62 are built in the lower ring 30, and the lower outer protrusion 65 gradually moves upward as it goes to the inner side of the lower ring 30 (on the center axis side of the lantern). Protrusively inclined from the horizontal. The inclination angle corresponds to a longitudinal section in the vicinity of the lower edge portion of the sack 10. This downward outer protrusion 65 corresponds to the “fitting prevention portion” of the present invention.
And the front-end | tip part of the downward outer side protrusion part 65 is located in the outer side (side in the direction away from the center axis line of a lantern) rather than the upper ring 20 (the outer edge part).

Next, the effect of this lantern will be described.
When using this lantern, as shown in FIG. 8A, the upper ring 20 and the lower ring 30 are separated from each other.
On the other hand, when the use of the lantern is ended and stored, as shown in FIG. 8B, the upper ring 20 and the lower ring 30 are brought into a compressed state. Note that this compressed state (FIG. 8B) is a state where the compressed state (not including the over-compressed state) is slightly expanded from the most compressed state.

As shown in FIG. 8B, in the compressed state, the lower outer protrusion 65 abuts against the upper ring 20 (the lower edge). To be precise, the abutment is indirectly in contact with the upper edge of the fire bag 10 interposed therebetween. Thus, the upper ring 20 is prevented from further descending (fitting into the lower ring 30).
In this way, even with this lantern, it is effectively prevented from becoming over-compressed, and the vicinity of the lower edge of the fire bag 10 is prevented from being damaged.

[Example 3]
Next, a lantern according to a third embodiment of the present invention will be described with reference to FIGS. 9 and 10 with a focus on differences from the first embodiment.
Also in this lantern, a plurality of (for example, three) upper attachment members 150 are attached as in the first embodiment.
Each upper mounting member 150 is formed by cutting a metal plate by punching or the like, or by a synthetic resin.
Each upper mounting member 150 has an upper leg 152 and an upper inner protrusion 155.
The upper leg 152 has a narrow strip shape. The upper inner projecting portion 155 has a substantially circular flat plate shape perpendicular to the upper leg portion 152, and a hole (reference numeral omitted) is formed at the center.

The upper mounting member 150 is configured such that the upper leg 152 is forcibly inserted from the lower side into the portion between the upper inner ring 21 and the upper outer ring 22 and, if necessary, an adhesive. Are bonded to the upper inner ring 21 and the upper outer ring 22 and fixed to the upper ring 20.
Thus, the upper leg 152 is built in the upper ring 20, and the upper inner protrusion 155 protrudes substantially horizontally inside the upper ring 20 (on the side of the central axis of the lantern). This upper inner protrusion 155 corresponds to the “fitting prevention portion” of the present invention.
And the front-end | tip part (part located in the innermost part of the upper ring 20) of the upper inner side protrusion part 155 is located inside (the center axis line side of a lantern) rather than the lower ring 30 (the inner edge part).
And the effect similar to the effect in Example 1 is obtained.

[Example 4]
Next, a lantern according to a third embodiment of the present invention will be described with reference to FIGS. 11 and 12 with a focus on differences from the first embodiment.
One upper mounting member 250 is attached to the upper ring 20.
The integrated upper mounting member 250 is formed by bending a substantially strip-shaped metal plate having elasticity. That is, for example, four upper inner projecting portions 255 are formed on the lower edge portion of the band plate-like upper mounting main body portion 252. The upper inner projecting portion 255 is formed by being bent 90 degrees from the upper mounting main body portion 252.
The integrated upper mounting member 250 (upper mounting main body portion 252) has elasticity and has a length (same or slightly shorter) substantially corresponding to the inner circumference of the upper ring 20 (upper inner ring 21). .

The integrated upper mounting member 250 is elastically curved so that the upper inner projecting portion 255 faces the inner direction, is inserted into the upper ring 20, and the inner peripheral surface of the upper ring 20 by its own elastic restoring force. Press against the inner peripheral surface of the upper inner ring 21. The integral upper mounting member 250 is attached to the upper ring 20 by an adhesive as necessary along with the frictional force based on the pressing force.
At that time, the four upper inner protrusions 255 are attached so as to be positioned at substantially the same height as the lower edge of the upper ring 20.
Thus, the upper inner projecting portion 255 projects substantially horizontally inside the upper ring 20 (on the side of the central axis of the lantern). The upper inner projecting portion 255 corresponds to the “fitting prevention portion” of the present invention.
And the effect similar to the effect in Example 1 is obtained.

It should be noted that the above is only a few examples of the present invention, and it is needless to say that the present invention can be implemented in various modifications based on the knowledge of those skilled in the art.
For example, the number of upper inner protrusions (55, 155, 255) / lower outer protrusions (65) can vary.
Furthermore, there may be various types of structures of the upper inner protrusion (55, 155, 255) / lower outer protrusion (65).
