DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fixture used to fix a tension ring and a decorative ring of a fire bag main body constituting a fire bag of an Ouchi lamp, and a fire bag using the fixture.

[0002]

2. Description of the Related Art Generally, as shown in FIGS. 8 and 9, a fire box of an Ouchi lantern is provided with a wooden tension ring 41 at the upper and lower ends of a vertically expandable and contractible fire bag body 40. Groove 43
It is manufactured by being fixed inside. In order to fix the tension ring 41 to the decorative ring 42, a suitable number of ball pieces 44 cut into a rectangular shape are pressed into a suitable number of locations in the groove 43, and the friction force causes the tension ring 41 to form the groove. 43 is prevented from falling out.

[0003]

However, since the ball paper piece 44 has a flat surface and becomes thinner when dried, the ball ring piece 44 does not have a sufficient retaining action of the tension ring 41, and in particular, a fire bag. Since the upper upper decorative ring is used while being hooked and held on the pin of the fire column of the gantry by the hanging string, the upper tension ring is pulled out from the groove 43 under the own weight and shrinkage force of the fire box main body 40. Because it was urged in the direction, it could fall off the upper makeup wheel and become unusable. If the ball piece 44 is tightly packed in the groove 43 in order to increase the retaining force, the workability is inferior because the waist is bent or the tip is bent.

SUMMARY OF THE INVENTION The present invention is to solve the above-mentioned conventional problems, and the invention of claim 1 provides a fire bag fixing device which can firmly fix a tension ring to a decorative wheel and has excellent workability. It is an object of the invention according to claims 2 and 3 to provide a fire bag in which an easily detachable upper tension ring is securely fixed to an upper decorative wheel so that the fire bag body can be prevented from falling off.

A fire bag main body 25 formed by connecting a translucent material 24 such as silk or Japanese paper to the outer periphery thereof, a wooden upper decorative ring 26 into which the upper tension ring 21 is fitted and fixed, and the lower tension ring 22 And a lower decorative wheel 27 into which the lower decorative ring 27 is fitted and fixed.

When the fire bag 3 is attached to the gantry 2, the lower decorative wheel 27 is fitted to the outer peripheral portion above the flange of the base plate 11 as shown in FIG. The claw pieces 17 rotated around the shaft 16 are engaged with the upper end surfaces of the lower decorative ring 27 and the lower tension ring 22 to prevent them from falling off, and the hanging straps 28, 28 attached to the upper decorative ring 26 are fired. Hooks are provided on the pins 18, 18 protruding from the side portions of the columns 13, 13 to hold the firebags in an extended state.

FIG. 3 shows a structure for fixing the upper tension ring 21 to the upper decorative ring 26 as shown in FIG. 3. In order to fix the upper tension ring 21 in the groove 29 of the upper decorative ring 26, the above-described conventional bolt is used. 4 and a fixing tool 31 shown in FIG. 4, and in this example, an eyelet 36 which passes through the upper decorative wheel 26 and the fixing tool 31 in the diameter direction is used.

As shown in FIG. 4, the fixing member 31 is a partially cylindrical curved piece 3 curved along the side surface of the upper tension ring 21.
2 is provided with a collar 33 at one end thereof, and on both sides of the curved piece 32,
This is a plastic molded product provided with a plurality of ridges 34 extending in the circumferential direction. In this example, a soft polystyrene resin is used as the plastic. In this example, the collar 33 projects on both the inner and outer diameter sides of the curved piece 32. However, this collar 33 is on the outer diameter side (the upper tension ring 21 side in FIG. 3).
It is good also as what protrudes only to.

When the upper decorative wheel 26 is mounted, the upper tension ring 21 and a plurality of ball paper pieces 44 are provided on the inner diameter side of the upper decorative ring 21 in the groove 29 of the upper decorative wheel 26 (in this example, the mounting position of the hanging string 28 is set). (Four places), and between the ball piece 44 and the upper tension ring 21, the flange 33 is pressed to press-fit the curved piece 32 of the fixture 31. Thereafter, a hole 37 is drilled through the upper decorative wheel 26 (along with the curved piece 32 and the ball paper piece 44) in a diametrical direction, and a fitting 36 is removably fitted into the hole 37. Hanging string 28 on eyelet 36
Insert the end of.

Due to the press-fitting of the curved piece portion 32 of the fixing tool 31, the ridge 34 becomes the upper tension ring 21 and the ball paper piece 44.
The outer diameter side of the upper tension ring 21 is pressed against the outer diameter side wall surface 29b of the groove 29, and the ball paper piece 44 is
Is pressed against the inner side wall surface 29a of the upper ring 21 and the frictional force prevents the upper ring 21 from dropping downward, and the collar 33 is engaged with the lower end surface of the upper ring 21 and the upper ring 2
1 is prevented from falling down.

Further, in this example, since the ferrule 36 inserted through the curved piece 32 together with the upper decorative wheel 26 fixes the fixing tool 31 to the upper decorative wheel 26, the fixing tool 31 is thereby moved downward of the fixing tool 31. Of the upper tension ring 21 by the collar 33 of the fixture 31 integrated with the upper decorative ring 26.
Is more reliably prevented from falling down.

Since the fixture 31 is made of plastic, it does not bend or bend as in the case of the ball paper piece 44, so that the press-fitting operation can be performed quickly and easily, and the workability is improved.

On the other hand, as shown in FIG. 5, a structure for fitting the lower tension ring 22 to the lower decorative ring 27 is as shown in FIG. The lower tension ring 22 is pressed into the inner diameter side of the lower tension ring 22, and the frictional force prevents the lower tension ring 22 from being pulled out of the lower decorative ring 27. When the lower decorative ring 27 is attached to the base plate 11, the claw pieces 17 are engaged with the upper end surface of the lower tension ring 22 to prevent the lower pulling ring 22 from being pulled out when the fire bag is extended. The fixing structure by the paper sheet 44 is the base plate 1 of the fire bag 25.
The fixture 31 is not used in this example because it is only necessary to prevent the lower tension ring 22 and the lower decorative ring 27 from being detached before or after the attachment to the base 1. However, the fixing tool 31 may be used to form a fitting and fixing structure similar to that of the upper tension ring 21. In this case, the use of the fixing tool 31 which is not easily deformed improves workability.

When the Ouchi lamp 1 is stored after use, the gantry 2 and the like can be disassembled and the fire bag 3 can be stored in a folded state as in the conventional case. When it is necessary to remove the decorative ring for repairing the trunk of the fire box body 25 or for putting a family crest on the upper decorative ring 26, the upper decorative ring 26 removes the hanging string 28 and the eyelet 36, and removes the fixing tool 31. When the upper tension ring 21 is
9 and can be reassembled in the reverse order. At this time, the fixture 31 can be easily removed from the groove 29 by hooking or gripping the collar 33 of the fixture 31 at the tip of the tool.

In the above example, the groove 2 of the upper decorative wheel 26 is used.
In FIG. 9, the curved piece 32 of the fixture 31 was pressed into the space between the side surface of the upper tension ring 21 and the ball paper piece 44.
If the amount of protrusion of the ball 3 toward the outer diameter side is large, the ball paper piece 44
May be inserted into the upper tension ring 21 side, and the fixing tool 31 may be press-fitted between the ball paper piece 44 and the inner diameter side wall surface 29a of the groove 29.

FIG. 6 shows another example of the embodiment of the present invention, in which the fire bag 3 has a double structure and has an upper tension ring 21A and a lower tension ring (not shown). It has an inner fire main body 25A, an outer fire main body 25B provided with an upper tension ring 21B fitted to the outer diameter side of each of the above tension rings, and a lower tension ring (not shown). Then, the upper tension rings 21A and 21B are overlapped and the groove 29 of the upper decorative ring 26 is formed.
The curved piece 32 of the fixing tool 31 is inserted between the upper tension ring 21A on the inner diameter side and the inner diameter side wall surface 29a of the groove 29.
Press the part.

The ridge 34 of the curved piece 32 is
A and the outer diameter side of the upper tension ring 21B is pressed into contact with the outer diameter side wall surface 29b of the groove 29 via the upper tension ring 21A, and the flange 3 is formed.
2 is engaged with the lower end surfaces of the upper tension rings 21A and 21B, thereby preventing the upper tension rings 21A and 21B from falling down.

Further, in this example, the fitting 31 inserted into the hole 37 drilled in the same manner as in the above example prevents the fixture 31 from dropping downward, and the upper tension ring 21A as in the previous example. , 21B is more reliably prevented from falling down.

Although not shown, the fire bag bodies 25A, 25B
Each of the lower tension rings is fitted in the groove of the lower decorative ring in a superposed state, and is fixed by press-fitting the ball piece 44 in the same manner as in the above-described example. You may.

In each of the above examples, the fixing tool 31 is arranged at the position where the hanging string 28 is attached. However, when the fixing tool 31 is arranged at a position deviated from the position where the hanging string 28 is attached, as shown in FIG. 36 may be omitted, or the fixing tool 31 may be held by inserting a split pin with a hole 37 in place of the stopper 36 to insert a split pin.

The present invention is not limited to the above examples, and for example, the shape and material of each part may be other than those described above. Further, since the fixing tool 31 used in each of the above examples has the ridges 34 provided on both the inner and outer diameter side surfaces of the curved piece 32, the upper tension ring is pressed by the both ridges 34 and bites into the groove 29 by a large frictional force. Although it has an advantage of being able to be held in a curved shape, a configuration in which the ridge 34 is provided only on one side surface (preferably the inner side surface) of the curved piece 32 may be adopted.

[0028]

As described above, according to the first aspect of the present invention, the ridge provided on the side surface of the curved piece bites into the side surface of the adjacent member at the time of press-fitting into the groove of the decorative wheel, and the groove is formed in the groove. Increasing the pressure contact force between each member, the collar engages with the end face of the tension ring to prevent the tension ring from coming out, and the whole fixture is made of plastic, so it does not break or bend. The fastening ring can be firmly fixed in the groove of the decorative ring, and a fire bag fixing device excellent in workability can be obtained.

According to the second aspect of the present invention, by pressing the fixing tool of the first aspect, the upper tension ring is securely fixed to the upper decorative ring, and a fire bag capable of preventing the fire bag body from falling off can be obtained. Can be

According to the third aspect of the present invention, in addition to the press-fitting of the fixing device of the first aspect, the fixing device is fastened to the upper decorative wheel by means of a hook for inserting a hanging string, so that the upper covering is fixed. The loop can be more securely fixed to the upper decorative ring, and a fire box that can more reliably prevent the fire box body from falling off can be obtained.
