Description

  The present invention relates to a paper lantern having a base called a so-called fire tray, a column erected from the base, and a cylindrical fire bag stretched so as to cover the base and the column. More particularly, the present invention relates to a lantern that can be easily assembled and disassembled, and can be stably used independently, so that it can be easily used in various fields such as lighting, advertising, and decoration as well as for funerals.

  There are various types of lanterns, such as a floor-standing type, a hanging type, and a bowed type, but the lanterns have basically the same structure. A bamboo frame is used to make a frame, and Japanese paper or silk cloth is applied to the outside of the frame to create a cylindrical fire bag. The main body of the lantern is that the upper and lower rings are attached to the upper and lower mouths of the sack.

  Further, for example, in the case of a row lantern lantern, two pillars called upper legs are set up on a base called a lokuro or a fire plate, and the above-mentioned cylindrical fire bag is fitted to cover the pillars. The base is generally disk-shaped and has a projection and a hole for standing a candle and an electric lamp in the center, and usually has three legs called lower legs on the lower surface. Two struts are usually erected on the upper surface of the pan, and the upper ring of the lantern is hung with a string at the upper end, and the upper ends of the struts are fixed to each other with a horizontal beam called a cloud hand. The lower ring of the lantern is fixed to the base with a clasp. When disassembling the paper lantern, reverse the procedure to separate the hands, firebag, support column, and pan, and fold the firebag into a box.

Moreover, in the hanging type lantern, the upper ring of the lantern is hung with a string on a horizontal bar called a hand plate, and the hand plate is hung from a ceiling or a pillar. Furthermore, the lanterns that are often used in festivals do not use handboards, but hang the upper ring from the eaves or ceiling. A bow-shaped lantern used for a welcome lantern or a portable lantern is used by fixing the upper and lower rings of the lantern at both ends of a bow-shaped handle. In the case of these lanterns, the bottom plate of the lower wheel is used as a fire pan.
There are various forms of lanterns as described above, but basically there is only a difference in the mounting form. The lantern body itself has no difference in the structure in which the upper and lower rings are attached to the upper and lower mouths of the sack. .

  Various types of lanterns have historical backgrounds and their installation forms have been devised and developed, but all have the problem that they are complicated and troublesome to attach and detach to and from the baking tray. Also, the floor-standing type is floor-standing, and the hanging type is hanging, and the usage pattern is limited, and it is not possible to select an arbitrary usage pattern.

  In contrast to such a conventional lantern, the present inventors have proposed a lantern as described in Patent Document 1 below. In this lantern, support posts are erected from the base, and a fire bag is stretched over the base and the support. At this time, the lower end portion of the sack is hung on the periphery of the base and fitted to the outside, and the upper end of the support is hung on the upper end of the sack. In this state, an elastic member provided at the intermediate portion of the support column is used to apply tension to the fire bag, and the fire bag is stretched.

  This lantern is easy to assemble and disassemble the lantern body and the member that fixes it, and can be used in various forms. It is easy to use in various fields such as lighting, advertising, decoration, etc. as well as for funerals. Can be used. However, in order to install it on the floor, legs are required, and for stable installation, a balanced arrangement of legs is required.

  In view of the problems of the conventional lanterns, the present invention is easy to assemble and disassemble the lantern body and the member for fixing the lantern body, can be used in various forms, and without special legs. The purpose of the present invention is to provide a lantern that is stable and self-reliant, and that automatically returns to a stand-up state even when it falls over due to external forces.

  In the present invention, in order to achieve the above-mentioned object, the lower end and the upper end of the squib 1 are supported by the base 2 and the upper end of the support 3 standing upright from the support 2 and provided on the support 3. The fire bag 2 was stretched by applying tension to the fire bag 1 by the elasticity of the elastic member 18. In addition, at least the central part of the bottom surface 15 of the base 2 has a projecting curved surface shape, and the center of curvature of the projecting curved surface shape of the bottom surface 15 is set at a position higher than the center of gravity G of the entire lantern.

That is, the lantern according to the present invention has a projecting curved shape having a center of curvature at a position where at least the center of the bottom surface of the base 2 forming the bottom of the lantern is higher than the position of the center of gravity G of the lantern. Set up on the floor.
Furthermore, the upper and lower mouth portions of the fire bag 1 are not provided with an upper wheel or a lower wheel. First, the lower end portion of the fire bag 1 is fixed by hanging the lower end opening 5 around the periphery of the base 2. On the other hand, a column support 7 is provided at the upper end portion of the sack 1 and the upper end of the column 3 erected from the base 2 is detachably received by the column receiver 7. And the tension | tensile_strength is given and tensioned with the elasticity which the support | pillar 3 has.

  In such a lantern according to the present invention, an upper ring and a lower ring are not required at the upper and lower mouth portions of the fire bag 1, and the opening 5 at the lower end of the fire bag 1 is hung on the peripheral edge 9 of the base 2. 1 can be directly attached to the base 2. Then, the upper end of the column 3 erected from the base 2 is detachably hung on the column support 7 at the upper end of the fire bag 1, and the upper end of the column 3 is elastically moved upward by an elastic member 18 provided in the middle part of the column 3. By pushing up and applying tension to the firing bag 1, the shape of the firing bag 1 can be adjusted and held. As a result, the lantern can be easily assembled and disassembled in the reverse order.

  Further, in this lantern, at least the center portion of the bottom surface 15 of the base 2 has a projecting curved shape having a center of curvature at a position higher than the position of the center of gravity G of the entire lantern, and the bottom surface 15 is placed on the floor. Thus, even if the lantern is temporarily inclined due to an external force, the original standing state is caused by the moment between the gravity applied to the center of gravity G and the reaction force received by the bottom surface 15 of the base 1 having a projecting curved shape from the floor. Since it returns to step 2 and becomes independent, it becomes possible to make it stable and independent. Further, by providing the power supply 6 and the sensor switch 14 for opening and closing the power supply circuit on the base 2, some physical change is given so that the sensor switch 14 is closed from the outside of the chimney 1. Thus, the light 8 can be blinked.

  As explained above, the lantern according to the present invention can be easily assembled and disassembled, and is stable and self-supporting when installed, so that it can be used in a stable standing state by selecting an appropriate form for purposes such as funerals, advertisements and festivals. I can do it. In addition, by changing the height of the column 3 attached to the base 2, it is possible to make a wide variety of usage forms, such as using differently shaped fire bags on the same base 2.

  In the present invention, the upper and lower mouth portions of the sack 1 are not provided with upper and lower rings, but the upper and lower mouth portions of the sack 1 are directly attached to the upper ends of the base 2 and the support column 3, and the elastic member provided on the support column 3. 18, tension was applied to the firing bag 1 so that the shape of the firing bag 1 was adjusted and held. Furthermore, at least the central part of the bottom surface 15 of the base 2 has a projecting curved shape, and the center of curvature is set higher than the center of gravity G of the lantern, thereby enabling stable installation.

Hereinafter, the best mode for carrying out the present invention will be described in detail with reference to examples.
1 and 2 show an entire lantern according to an embodiment of the present invention, and FIGS. 3 to 5 show enlarged views of respective parts of the lantern according to the embodiment. As shown in these drawings, the lantern includes a fire bag 1, a base 2, and a column 3.

  The fire bag 1 is a shell-shaped part that forms the outer shape of the lantern. This fire bag 1 has a large number of rings made of bamboo rods and other wires using a mold arranged one above the other, or a wire that is joined together using a mold and arranged in a spiral shape up and down. And form a framework. And the paper bag, cloth, etc. are stuck on the outer side of the framework, and it is set as the fire bag 1. The lower end portion of the squib 1 is a lower end opening 5, and the portion is densely stacked with a frame made of a wire rod. The lower end opening 5 of the fire bag 1 is circular when no force is applied thereto, but it can be deformed, for example, it can be flattened by applying a force in the radial direction. The portion above the lower end opening 5 of the fire bag 1 has a gradually increasing diameter and is bulged with a curved surface on the outside.

The upper end portion of the fire bag 1 is closed, and a disk-shaped support holder 7 is provided on the inner surface of the upper end portion. FIG. 4 shows details of the upper end portion of the fire-blade 1 having the support column 7. The upper surface of the support column 7 is a projecting curved surface, and the upper surface is fixed to the inner surface of the upper end of the sack 1 by means such as adhesion. A recess 16 for fitting the upper end of the upper column 11 of the column 3 to be described later is provided on the lower surface of the column receiver 7. The support column 7 is preferably transparent and allows light to pass through.
The fire bag 1 shown in FIGS. 1 and 2 configured as described above has a bottomed and uncovered egg-like shape as a whole.

  As shown in FIGS. 1 to 3, the base 2 is called a fire tray or a rocker, and its outer diameter is slightly larger than the diameter of the lower end opening 5 of the fire bag 1. In the illustrated example, the base 2 has a disk shape, and its peripheral edge 9 is rounded and chamfered. Correspondingly, the lower end opening 5 of the squib 1 is also a circle having a slightly smaller diameter. The upper surface of the base 2 is flat, and the bottom surface 15 is a projecting curved surface. Specifically, at least the central portion of the bottom surface 15 has a protruding spherical shape with a radius of curvature R, and the center of the radius of curvature R is above the central portion of the upper surface of the base 2. The projecting spherical portion may extend over the entire bottom surface 15 of the base 2 or may be only the central portion thereof.

  On the upper surface of the base 2, a lamp 8 and a power supply circuit for lighting it are configured. The power supply circuit includes a power source 6 such as a battery, a main switch 5 and a sensor switch 14, and the power source 6 is connected to the lamp 8 by opening and closing (on-off) the sensor switch 14 with the main switch 5 closed (on). It is shut off and the light 8 flashes. As the lamp 8, an LED lamp with low power consumption is used. As the sensor switch 14, an impact sensing switch that detects and closes an impact sound such as applause of a person, an optical sensor switch that detects and opens a light, or a human sensor that detects and closes a person is detected. An infrared sensing switch called a switch can be used.

  A column 3 is erected from the center of the base 2. This support column 3 is a pipe-like structure having a two-stage structure comprising a lower support column 10 erected from the base 2 by means such as screwing and an upper support column 11 that is detachably fitted to the upper end of the support column and joined together. It has become. The outer diameter of at least the lower end of the upper column 11 is slightly smaller than the inner diameter of at least the upper end of the lower column 10, and the lower column of the column 11 is joined by being inserted into the upper end of the lower column 10.

  As shown in FIGS. 1, 2, and 5, a compression spring is incorporated as an elastic member 18 near the upper end of the lower column 10. The elastic member 18 hits the lower end of the upper column 11 fitted into the upper end of the lower column 10. When the upper column 11 is pushed downward, an elastic force proportional to the pushed depth is urged. As a result, elasticity is applied to the column 3.

Next, a description will be given of a procedure for attaching the fire bag 1 to the base 2 and the column 3 for the lantern having such a configuration.
First, as shown in FIG. 1, the lower support column 10 is attached to the support column 3, and the lower end of the upper support column 11 is inserted on the lower support column 10 to join the support columns 3 together. In this state, the fire bag 1 is placed on the support column 3 from the lower end opening 5, and the upper end of the upper support column 11 is fitted into the recess 16 of the support column 7 at the upper end of the fire bag 1 as shown in FIG. 4.

Next, the upper part 11 is pushed down to compress the elastic member 18, and the fire bag 1 is extended downward. Then, the lower end opening 5 of the fire bag 1 is slightly deformed, and the base 2 is fitted into the lower end opening 5 while being slightly inclined with respect to the base 2. And the attitude | position is arranged so that it may settle in the state which the lower end opening part 5 returned to the original form, and the peripheral edge 9 of the base 2 was fitted inside. Thereby, as shown in FIGS. 2 and 3, the assembly of the lantern is completed.
In this state, the peripheral edge 9 of the base 2 is hung on the lower end opening 5 of the sack 1, and the column 3 is extended by the elasticity of the elastic member 18 provided in the column 3, and the tension is applied to the sack 1 by the elasticity. As a result, the shape of the fire bag 1 is stretched and the shape of the egg-shaped lantern is maintained.

  As shown in FIGS. 2 and 3, the center of gravity G of the lantern is at a portion of the base 2 or at a low position close thereto. On the other hand, the center of the curvature radius R of the protruding curved surface of the bottom surface 15 of the base 1 is higher than this. Therefore, if the lantern is installed by placing the bottom surface 15 of the base 1 having the projecting curved surface at the center on the floor, the lantern can always be stably held up. Even if an external force is applied to the lantern and it is temporarily tilted, the lantern is erected by the moment between the gravity applied to the center of gravity G and the reaction force received by the bottom surface 15 of the base 1 having a projecting curved shape from the floor. Return to the posture immediately.

  The main switch 5 of the power supply circuit of the lamp 8 is closed (ON) in advance before attaching the fire bag 1. In this state, when the sensor switch 14 is an impact detection switch that closes by detecting an impact sound such as applause of a person, the impact sound such as applause is detected and the lamp 8 is turned on. When the sensor switch 14 is an optical sensor switch that opens by detecting light, the lamp 8 is turned on by detecting that the surrounding has become dark. Alternatively, when the sensor switch 14 is a human sensor switch that detects the presence of a person and closes, the lamp 8 is turned on when there is a person nearby.

  When disassembling the fire bag 1 from the base 2 and the support column 3, the procedure is reversed. That is, the lower end opening 5 of the hook 1 is removed from the peripheral edge 9 of the base 2, and then the pole holder 7 of the gun 1 is removed from the upper end of the upper pole 11 of the pole 3 while folding the flame 1 upward. Thereafter, the upper column 11 is removed from the lower column 10 of the column 3. Furthermore, if the lower column 10 of the column 3 is also taken out from the base 2, it can be further disassembled more compactly.

  6 to 9 show a second embodiment of the lantern according to the present invention. The basic configuration of this lantern is basically the same as that of the lantern described above with reference to FIGS. 1 to 5, and the basic configuration includes a fire bag 1, a base 2, and a support 3. The parts corresponding to the lanterns described above with reference to FIGS.

  This lantern's sack 1 is similar to the one described above, in which a large number of rings made of bamboo rods and other wires are placed side by side using a mold, or they are joined together using a mold. Are arranged in a spiral shape up and down to form a framework, and paper or cloth is pasted on the outside. The bottom part of the fire bag 1 is a lower end opening part 5, which is closely overlapped with a framework made of a wire ring. As shown in FIGS. 6 and 7, the lantern's fire bag 1 according to this embodiment has a bottle shape.

  Further, the upper end portion of the fire bag 1 is an open mouth, and the frame is densely overlapped with a frame made of a wire ring. Further, a disc-shaped support holder 7 is fitted into the upper end opening of the fire bag 1 and fixed by means such as adhesion. Details of the column support 7 are shown in FIGS. The support column 7 is provided with an insertion hole 20 that is deviated from the center and has a relatively large diameter, and a slit 21 that is narrower than the diameter of the insertion hole 20 is provided from the insertion hole 20 toward the center of the support column 7. ing.

  The base 2 and the column 3 erected from the center of the base 2 are exactly the same as those of the above-described embodiment, and detailed description thereof is omitted. However, the upper end of the upper column 11 of the column 3 is slightly different from that of the above-described embodiment. At the upper end of the upper column 11 of the column 3, a fire bag hook 13 for detachably hanging the column holder 7 of the bag 3 is attached. The fire bag hook 13 is a pin-shaped member having a flange made of a washer or the like in the middle portion and a head portion provided on the flange portion, and is attached to the upper end of the upper column 11 by means such as a screw. As shown in FIG. 8, the flange at the intermediate portion of the hook 19 has a smaller diameter than the insertion hole 20 of the column support 7 at the upper end of the hook 1. Further, the diameter of the flange of the sparkbag 13 is larger than the width of the slit 21 of the support column 7 at the upper end of the sparkbag 1, and the shaft diameter of the sparkbag 13 is smaller than the width of the slit 21 of the support column 7.

Next, a description will be given of a procedure for attaching the fire bag 1 to the base 2 and the column 3 for the lantern having such a configuration.
First, as shown in FIG. 1, the upper column 11 is removed from the lower column 10 of the column 3 in advance. In this state, with the sack 1 slightly folded up and down, the lower strut 10 is inserted into the bottom part 4 of the sack 1 and then the lower end opening 5 of the sack 1 is slightly deformed, The base 2 is inserted into the fire bag 1 from the lower end opening 5 of the fire bag 1 while the base 2 is slightly inclined. And the attitude | position is arranged so that it may settle in the state which the periphery 9 of the base 2 was fitted in the lower end opening part 5 of the fire bag 1. FIG.

  Next, the upper column 11 of the column 3 is inserted into the flame bag 1 through the insertion hole 20 of the column holder 7 of the bag 1, and the lower end of the upper column 11 is inserted into the upper end of the lower column 10. Subsequently, the upper column 11 is pushed in against the elasticity of the elastic member 18, the fire bag 1 is extended upward, and the head 15 of the bag holder 13 is protruded from the insertion hole 20 of the column holder 7, Then, the shaft of the spark-bag 13 is inserted into the slit 21. In this state, the pushing of the upper support 11 is released, the flange 14 is applied to the support 7 of the fire bag 1 by the elasticity of the elastic member 18, and the support 7 of the fire bag 1 is lifted upward by the elasticity. Give tension to 1. In this state, the peripheral edge 9 of the base 2 is hung on the lower end opening 5 of the fire bag 1, and tension is applied to the fire bag 1 in the vertical direction by the elastic member 18, so that the fire bag 1 is stretched, The shape can be maintained.

  This lantern can also be used as a floor-standing lantern, since it can be stably and independently standing with the bottom surface 15 of the base 2 having a projecting curved surface at least in the center portion installed on the floor. The blinking operation of the lamp 8 in use is the same as the lantern described above with reference to FIGS. That is, the lamp 8 blinks by the opening / closing operation of the sensor switch 14 with the main switch 5 closed (turned on).

  When disassembling the fire bag 1 from the base 2 and the support column 3, the procedure is reversed. That is, the shaft of the hook 13 is moved from the slit 21 to the insertion hole 20 side, and the hook 13 of the support 3 is removed from the support 7 of the support 1. Thereafter, the upper support 11 is removed from the lower support 10 of the support 3 while folding the fire bag 1 downward. Subsequently, while slightly deforming the bottom portion 4 of the chimney 1 and slightly tilting the base 2 with respect to the bottom of the chisel 1, the base 2 is taken out from the lower opening 5 of the chisel 1, The lower support column 10 is also taken out. Thus, the state shown in FIG. 6 is obtained. The fire bag 1 can be folded down vertically and the lower support 10 can be removed from the base 2 to be further compactly disassembled.

  The lantern according to the present invention can be easily assembled and disassembled, and even if it is tilted as a floor-standing type, the lantern returns to its original posture and then becomes independent and can be stably installed. As a result, it can be used easily and safely in various fields such as lighting, advertising, and decoration as well as for funerals.
