a indicates both base ends 2a of both bifurcated handles 2 and 3;
3a, and a support hole 1 formed therein.
Both support shafts 5 and 6 are inserted through 4, 15, 16, and 17. Enlarged diameter portions 14a, 16a are formed in the support holes 14, 16 of both base end portions 2a, 3a of both handle portions 2, 3, and both ends of both support shafts 5, 6 are formed in each of the enlarged diameter portions 14a, 16a. The heads 5a and 6a formed in are locked.

よりも小さくなる。 In this embodiment, the lengths of both support shafts 5 and 6 are changed and both ends of these are caulked to form heads 5a and 6a. The base end 4a of the blade 4 between both base ends 2a of the blade 2
is clamped, and both heads 6 of the other support shaft 6
a between both base ends 3a of the handle 3 on the ventral side.
The proximal end portion 4a of is clamped, and the clamping force varies depending on the lengths of both support shafts 5 and 6. That is, in this embodiment, the length of one support shaft 5 is shorter than the length of the other support shaft 6, and the difference in length between the two support shafts 5 and 6 constitutes a rotational resistance imparting means. ing.
The difference in the clamping force based on the lengths of the two support shafts 5 and 6 acts as a difference in the frictional force between the two handles 2 and 3 and the blade 4, and the difference in the clamping force between the two handles 2 and 3 on the back side of the sword blade 4. The rotational resistance becomes smaller than the rotational resistance of the handle 3 on the ventral side with respect to the blade 4.
不使用時、止め枠７を外し、両柄部２，３を把

２の回動が停止する。この状態では、両柄部２，
３が互いに重ね合わされ、それらの先端部２ｂ，
３ｂを止め枠７により連結すると、第７，８，９
図に示すように不使用状態となる。 When not in use, when the stopper frame 7 is removed and both handles 2 and 3 are gripped and rotated relative to the blade 4, only the dorsal handle 2 will first rotate, as shown in Figures 5 and 6. do.
When the back 11 side of the proximal end 4a of the blade 4 is inserted into the storage gap 8 of the handle 2 on the back side through the opening 8a, the inner surface of the opening 8a and the back 1 of the blade 4 are inserted.
Since the rotational resistance of the ventral handle 3 is smaller than the contact resistance generated between the ventral handle 3 and the ventral handle 3, only the ventral handle 3 rotates next. After that, the storage gap 10 of the ventral handle 3
When the cutting edge 12 side of the blade 4 is inserted through the opening 10a and the rotation of the handle 3 stops, only the back handle 2 rotates again, and the back 11 of the blade 4 is inserted into the storage gap 9. When the side is completely inserted, the rotation of the same pattern part 2 stops. In this state, both handles 2,
3 are superimposed on each other, and their tip portions 2b,
3b are connected by the stopper frame 7, the 7th, 8th, 9th
As shown in the figure, it is in an unused state.
このように、両柄部２，３の回動タイミングを
変えると、使用者の注意がそれぞれの柄部２，３
の回動操作のみに集中するので、従来技術の場合
と比較して、腹側の柄部３を把持した手の指を刀
身４の刃先１２により不用意に切つてけがをする
おそれはなくなり、安全性が向上する。 In this way, by changing the rotation timing of both handles 2 and 3, the user's attention is focused on each handle 2 and 3.
Since the focus is only on the rotational operation, there is no risk of inadvertently cutting the fingers of the hand gripping the ventral handle 3 with the cutting edge 12 of the blade 4 and causing injury, compared to the case of the prior art. Improves safety.
なお、この不使用状態では、両柄部２，３に形
成された凹部１８ａ，１９ａ及び凸部１８ａ，１
９ｂのうち、腹側の柄部３の凹部１９ａの一つに
形成された当接部２０に背側の柄部２の凸部１８
ｂの一つが当たつて両柄部２，３の先端部２ｂ，
３ｂが開き、その先端部２ｂ，３ｂを止め枠７に
より連結したとき腹側の柄部３の先端部３ｂがこ
の止め枠７に圧接されるようになつている。 Note that in this unused state, the recesses 18a, 19a and the protrusions 18a, 1 formed on both handles 2, 3
9b, the convex part 18 of the dorsal handle part 2 is attached to the contact part 20 formed in one of the recesses 19a of the ventral handle part 3.
When one of b hits, the tips 2b of both handles 2, 3,
3b is opened and the distal end portions 2b, 3b are connected by the stopper frame 7, the distal end portion 3b of the ventral handle 3 is pressed against the stopper frame 7.
逆に、使用時、止め枠７を外し、両柄部２，３
を把持して刀身４に対し回動させると、第１０図
に示すように、まず腹側の柄部３のみが回動す
る。そして、この柄部３がピン１３に当たつて停
止すると、次に背側の柄部２のみが回動し、第１
図に示す使用状態にすることができる。 On the other hand, when using it, remove the stopper frame 7 and attach both handles 2 and 3.
When the handle 3 is gripped and rotated relative to the blade 4, only the handle 3 on the ventral side first rotates, as shown in FIG. When the handle 3 hits the pin 13 and stops, only the handle 2 on the back side rotates and the first
It can be put into the usage state shown in the figure.
前述した実施例では、使用状態から不使用状態

抵抗よりも小さくすることにより、腹側の柄部３
がまず回動して同柄部３内に刀身４の刃先１２側
を収納した後、背側の柄部２が回動するようにし
てもよい。 In the above-mentioned embodiment, when switching from a used state to a non-used state, the handle portion 2 on the back side rotates first, and then the handle portion 3 on the ventral side rotates. However, by making the length of one support shaft 5 shorter than the length of the other support shaft 6, the rotation resistance of the handle portion 2 on the ventral side is made smaller than the rotation resistance of the handle portion 3 on the back side, so that the handle portion 3 on the ventral side rotates.
Alternatively, the handle 3 may be rotated first to house the cutting edge 12 side of the blade 4 within the handle 3, and then the handle 2 on the back side may be rotated.
そのほか両柄部２，３の回動抵抗付与手段とし

い。 In addition to the above-mentioned embodiment, the means for imparting rotational resistance to both handles 2 and 3 may be, for example, by making the clamping forces of both support shafts 5 and 6 the same, and
3 and the blade 4 may be provided with unevenness that slides against each other, or a spring may be used to press the space between them.

By providing rotational resistance imparting means between the base end 3a of one of the handles 3 and the base end 4a of the blade 4, the timing of rotation of both handles 2 and 3 can be changed. This allows the user's attention to be focused only on the rotation of the respective handles 2 and 3, and prevents the fingers of the hand gripping the ventral handle 3 from being accidentally cut by the cutting edge 12 of the blade 4, resulting in injury. There is less risk of this happening, improving safety.
