This is related to.

のような欠点を除去することを目的とするもので
ある。 Scissors with such a structure have existed for some time, but they were dangerous because the two main bodies could come off at right angles at unexpected times during use. The present invention aims to eliminate these drawbacks of conventional products.

性体７が縮むことができる距離よりは低い。 Next, the configuration of the present invention will be explained with reference to the drawings showing examples. The scissors of this invention have one blade in front of the handle.
Two main bodies 1 and 2, in which numbers 0 and 11 are connected, are rotatably mounted on a shaft 4. A shaft 4 is attached to one main body 1 so that both main bodies can be removed, and an elongated head 5 is provided at the end of the shaft 4, and the other main body 2 has a hole for passing the head 5. long and narrow hole 3
is drilled. A circular recess 9 is formed around the hole to prevent the head 5 of the shaft from protruding significantly beyond the surface of the other blade 11. The head 5 of the shaft and its respective longitudinal direction are in the same direction as the respective blade on which they are mounted. As a result, when the two main bodies 1 and 2 are orthogonally crossed, both the main bodies can be removed. A collar 6 is screwed onto the end of the shaft 4 that protrudes from the surface of the blade 10. A coil spring is interposed as an elastic body 7 between the collar and the blade 10, and the spring is loosely fitted to the shaft 4. A protrusion 8 is provided at the base of one of the blades 10, and the protrusion is provided in a position such that it locks onto the back 12 of the other blade 11 at a position in front of the two main bodies crossing at right angles. The height of this protrusion is lower than the distance that the elastic body 7 can contract.

本考案は以上のような構成であつて、両刀身１
０，１１を広げていつたときに、第１図に示した
ように両主体１，２が直交するよりも前に突起８
が他方の刀身の背部１２に係止するために、孔３
と軸の頭部５とは同一方向を向かず、したがつて
使用中に不意に両主体が直交して外れるのを防止
することができる。 The present invention has the above-mentioned configuration, with two blades 1
When 0 and 11 are expanded, the protrusion 8 appears before the two main bodies 1 and 2 are perpendicular to each other, as shown in Figure 1.
hole 3 to lock onto the back 12 of the other blade.
The head 5 of the shaft and the head 5 of the shaft do not face in the same direction, so that it is possible to prevent the two main bodies from accidentally coming off perpendicularly during use.

両主体を外すときには、一方の主体１を上に他
方の主体２を下にして軸の鍔６を下方に押すと、
弾性体７が縮んでその分だけ軸４及びその頭部５
が下がる。それと同時に他方の主体２も下がるの
で両主体の間に隙間が生じ、突起８が他方の刀身
の背部１２との係止状態が解除されて両主体を直
交させることができる。この結果、両主体を外す
ことができるのである。 To remove both main bodies, place one main body 1 on top and the other main body 2 on the bottom and press the shaft flange 6 downward.
The elastic body 7 contracts and the shaft 4 and its head 5 shrink by that amount.
goes down. At the same time, the other main body 2 also moves down, creating a gap between the two main bodies, and the protrusion 8 is released from being locked with the back 12 of the other blade, allowing the two main bodies to intersect at right angles. As a result, both subjects can be removed.

Claims

[Scope of utility model registration request]

Two main bodies 1 and 2 with sword blades connected in front of the handle are rotatably attached to a shaft 4, and the shaft 4 is attached to one main body 1 and attached to the end of the shaft so that both main bodies can be removed. is provided with an elongated head 5, and the other main body 2 is provided with an elongated hole 3 through which the head 5 passes, and is removed only when the two main bodies 1 and 2 are substantially perpendicular to each other. In scissors, the head 5 and the hole 3 are set so that their longitudinal directions are in the same direction when the two main bodies are orthogonal so that the shaft 4 protrudes from the surface of the blade 10. A collar 6 is provided at the end of the blade, and a compressible elastic body 7 is interposed between the collar and the blade 10, and a protrusion 8 is provided at the base of one of the blades 10. A pair of scissors is characterized in that the scissors are provided at a position so as to be engaged with the back part 12 of the other blade 11 at a position before the two main bodies are perpendicular to each other.
