[Industrial applications]

この考案は、折りたたみナイフに関するものである。 This invention relates to a folding knife.

【０００２】[0002]

[Prior Art]

従来折りたたみナイフは三図に示す如く、バネ（２６）により反時計回転方向に付勢されている背金（２５）を時計回転方向へ回転さす為、ハンドル（２０）の一部を背金押部（１９）に示すように、円弧状に切欠き刃（２１）を折りたたむ為に、背金押部（１９）の背金（２５）を直接押すと、バネ（２６）に抗して軸ピン（２７）を中心として、背金（２５）の係合凸部（２３）が回転し、刃（２１）の係合凹部（２４）との係合がはずれ、刃（２１）は軸ピン（２２）を中心として自由に回動し、折りたたむことができるものがあった。 As shown in FIG. 3, a conventional folding knife rotates a back metal (25), which is urged in a counterclockwise direction by a spring (26) in a clockwise direction, so that a part of the handle (20) is rotated. As shown in the metal pressing part (19), when the back metal (25) of the back metal pressing part (19) is directly pressed to fold the notch blade (21) in an arc shape, the spring (26) is resisted. Then, the engaging projection (23) of the back metal (25) rotates about the shaft pin (27), and the engagement of the blade (21) with the engaging recess (24) is released, and the blade (21) is disengaged. Some of them were able to freely rotate and fold around the shaft pin (22).

[Problems to be solved by the device]

これは次のような欠点があった。（イ）背金を押す為、ハンドル（２０）の上面を円弧状に切欠いた背金押部（１９）が必要であり、この為意匠が悪くなった。（ロ）背金（２５）をバネ（２６）に抗して、直接指で押す為、安全性を増すようにバネ（２６）を強くすると指が痛くなったり、又、寒い時手袋をすると、操作しにくいという欠点があった。本考案はこれらの欠点を除くためになされたものである。 This had the following drawbacks. (A) In order to push the back metal, the back metal pressing portion (19), which is an arc-shaped cut-out on the upper surface of the handle (20), is required, which deteriorates the design. (B) Since the back metal (25) is pushed directly against the spring (26) with a finger, if the spring (26) is strengthened so as to increase safety, the fingers may hurt, or if it is cold, it is a handbag. However, there was a drawback that it was difficult to operate. The present invention has been made to eliminate these drawbacks.

[Action]

柄（９）柄（９’）を持ち、てこ（１６）のハンドル（１５）を反時計回転方向へ動かすと、枢支点（１４）を介して作用部（１３）が反時計回転方向へ動き、背金（６）の圧下部（１２）をバネ（１０）に抗して時計回転方向へ動かす、それと同時に軸ピン（８）を介して係合凸部（３）が時計方向回転へ動き、刃（１）の係合凹部（２）より離脱し、その結果、刃（１）を折りたたむことができる。 When the handle (15) of the lever (16) is moved counterclockwise by holding the handle (9) handle (9 '), the action part (13) moves counterclockwise through the pivot point (14). , The pressing part (12) of the back metal (6) is moved in the clockwise direction against the spring (10), and at the same time, the engaging projection (3) is rotated in the clockwise direction via the shaft pin (8). It moves and disengages from the engagement recess (2) of the blade (1) so that the blade (1) can be folded.

【Example】

以下本考案の実施例について説明する。（イ）刃（１）の後部に、係合凹部（２）及び軸孔（４）を設ける。（ロ）背金（６）の前部に係合凸部（３）、中央部に軸孔（７）、軸孔（７）の下部に係止部（１７）、係止部（１８）、後端下部に圧下部（１２）を設ける。（ハ）てこ（１６）を略Ｌ状に整形し、一端を作用部（１３）、他端をハンドル（１５）とし、ハンドル（１５）は、柄（９）柄（９’）より突出する。又枢支点（１４）は、作用部（１３）に近づけて設ける。この時てこ（１６）の作用部（１３）から枢支点（１４）と、枢支点（１４）からハンドル（１５）の距離の比率を１：２又は１：３にすると背金（６）の圧下部（１２）を押し下げる力は１／２又は１／３となり、安全性を増す為バネ（１０）を強くしても、操作性は悪くならない。（ニ）柄（９）、柄（９’）間の前方に刃（１）を回動可能に軸ピン（５）で軸支する。中央部上方に背金（６）を軸ピン（８）で回動可能に軸支する。後部上方にてこ（１６）を枢支点（１４）で回動可能に軸支する。（ホ）背金（６）を反時計回転方向へ付勢するようにバネ（１０）を係止部（１７）係止部（１８）に置き、軸ピン（１１）により柄（９）柄（９’）間に取付ける。なお背金（６）を反時計回転方向へ付勢するものであれば４図に示すバネでも、その他のバネでも良いのである。又こて（１６）も作用部（１３）枢支点（１４）ハンドル（１５）をもつものであれば略Ｌ字形でなくても良いのである。 An embodiment of the present invention will be described below. (A) An engaging recess (2) and a shaft hole (4) are provided at the rear of the blade (1). (B) Engagement protrusions (3) on the front part of the back metal (6), the shaft hole (7) in the center part, the locking part (17) below the shaft hole (7), and the locking part (18) A lower part (12) is provided at the lower part of the rear end. (C) The lever (16) is shaped into a substantially L shape, one end of which serves as the working portion (13) and the other end of which serves as the handle (15), and the handle (15) protrudes from the handle (9) handle (9 '). Put out. The pivot point (14) is provided close to the action portion (13). At this time, if the ratio of the distance from the action portion (13) of the lever (16) to the pivot point (14) and the distance from the pivot point (14) to the handle (15) is 1: 2 or 1: 3, the back metal ( The force of pushing down the pressure lowering part (12) of 6) is 1/2 or 1/3, and the operability does not deteriorate even if the spring (10) is strengthened to increase safety. (D) A blade (1) is rotatably supported by a shaft pin (5) between the handle (9) and the handle (9 '). A back metal (6) is rotatably supported by a shaft pin (8) above the center. The upper part (16) of the rear part is pivotally supported on the pivot point (14). (E) The spring (10) is placed on the locking portion (17) locking portion (18) so as to bias the back metal (6) in the counterclockwise direction, and the handle (9) handle is held by the shaft pin (11). Install between (9 '). The spring shown in FIG. 4 or another spring may be used as long as it can bias the back metal (6) in the counterclockwise direction. The trowel (16) does not have to be substantially L-shaped as long as it has the action portion (13), the pivot point (14) and the handle (15).

【０００７】本案は以上のような構造で、これを使用するときは、柄（９）柄（９’）を片手で持ち、てこ（１６）のハンドル（１５）を反時計回転方向へ動かすと、枢支点（１４）を介して作用部（１３）が反時計回転方向へ動き、それと同時に背金（６）の圧下部（１２）をバネ（１０）に抗して時計回転方向へ動かす。それと同時に軸ピン（８）を介して係合凸部（３）が時計回転方向へ動き、刃（１）の係合凹部（２）より離脱し、刃（１）は折りたたむことができる。The present invention has the above-described structure. When using this structure, the handle (9) and the handle (9 ') are held by one hand, and the handle (15) of the lever (16) is moved counterclockwise. Then, the action part (13) moves counterclockwise through the pivot (14), and at the same time, the pressure lower part (12) of the back metal (6) resists the spring (10) in the clockwise direction. move. At the same time, the engaging projection (3) moves clockwise through the shaft pin (8), and is disengaged from the engaging recess (2) of the blade (1), so that the blade (1) can be folded.

【０００８】[0008]

[Effect of the device]

てこ（１６）を使って背金（６）を動かし刃（１）を折りたたむ為、バネ（１０）を強くしても、少しの力で操作でき、安全性の高い折りたたみナイフとなる。又背金押部（１９）が必要でない為意匠も良くなる。 Since the lever (16) is used to move the back metal (6) to fold the blade (1), even if the spring (10) is strengthened, it can be operated with a little force, and it is a highly safe folding knife. Further, the design is improved because the back metal pressing portion (19) is not required.
