Description

[Detailed description of the device]

【０００１】〔産業上の利用分野〕本考案は、理容師、美容師のような日常にハサミの使用頻度が多い人に、特に適した換え刃式ハサミに関する。[Field of Industrial Application] [0001] The present invention relates to a replaceable blade type scissors particularly suitable for a person such as a barber or a hairdresser who frequently uses scissors on a daily basis.

【０００２】〔従来の技術〕換え刃式ハサミは、刃先部とハンドル部とを別にし、これらをビス等にて一体化させることを構造としており、刃先部の切れ味が劣化して、円滑な切断作業が困難になれば、刃先部のみを新しい刃先部に交換するものである。このような新しい刃先部を交換する場面において、刃先部とハンドル部とを着脱するのに、微小なネジを使用し、なおかつその微小なネジ専用の特殊工具を必要としている。このために新しい刃先部の交換作業に困難をようしている。このような不具合を解消させるハサミが、実開平４−１４０４８号公報に開示されるが、この例は刃先部の凸部をハンドル部の凹部に差し込んで、ハンドル部に固定させるものである。この方式はビスを使用せずに、刃先部のハンドル部への取り付けが容易である。しかし、ハサミの切断作業を円滑にするためには、刃先部がハンドル部に対して振動せずに固定させる必要があります。この振動を発生させなくするには、刃先部の凸部とハンドル部の凹部との隙間を超微細にするための、高精度な加工技術が必要である。[Prior Art] The replaceable blade type scissors have a structure in which the blade tip portion and the handle portion are separated, and these are integrated by screws or the like, and the sharpness of the blade tip portion deteriorates, resulting in smoothness. When the cutting work becomes difficult, only the cutting edge is replaced with a new cutting edge. In such a situation of exchanging a new cutting edge, a small screw is used to attach and detach the cutting edge and the handle, and a special tool dedicated to the small screw is required. This makes it difficult to replace the new cutting edge. A scissor for eliminating such a problem is disclosed in Japanese Utility Model Laid-Open No. 4-14048, but in this example, the convex portion of the cutting edge portion is inserted into the concave portion of the handle portion and fixed to the handle portion. This method makes it easy to attach the cutting edge to the handle without using screws. However, in order to facilitate the cutting work of scissors, it is necessary to fix the blade tip to the handle without vibration. In order to prevent this vibration from occurring, a highly precise processing technique is required to make the gap between the convex portion of the cutting edge portion and the concave portion of the handle portion extremely fine.

【０００３】〔考案が解決しようとする課題〕本考案は、前述した如き基本構造を有する換え刃式ハサミではあるが、刃先部の交換をより簡易に、かつハンドル部に対する刃先部の固定をより強固にした、ハサミを提供することを課題とする。[Problems to be Solved by the Invention] Although the present invention is a replaceable blade type scissors having the above-described basic structure, the blade tip can be replaced more easily and the blade tip can be fixed to the handle more easily. The challenge is to provide strong scissors.

【０００４】〔課題を解決するための手段〕前述の課題を解決するために、本考案のハサミは、刃先部とハンドル部とからなる動刃と静刃とを対接し、ビスで両者を一体化させたハサミにおいて、刃先部に施工された凸部切り欠け部と、ハンドル部には刃先部に施工された凸部に対応する凹部とを係合させることを基本的手段とするものである。刃先部をハンドル部に着脱自在とした動刃と静刃を対接させ、両者をビスで一体化させたハサミにおいて、刃先部が平担なベース部と、該ベース部に施工された凸部切り欠部とを有し、ハンドル部が刃先部の凸部切り欠部に係合する凹部を有し、ハンドル部と刃先部のベース部とにビス孔を有することを特徴とする換え刃式ハサミを提供する。[Means for Solving the Problems] In order to solve the above-mentioned problems, the scissors of the present invention contact a moving blade composed of a blade tip portion and a handle portion with a stationary blade, and use a screw to connect them. In the integrated scissors, the basic means is to engage the convex notch formed on the cutting edge with the concave corresponding to the convex formed on the cutting edge on the handle. Is. In scissors in which a moving blade and a stationary blade, whose blade tip is detachable from the handle, are brought into contact with each other, and the two are integrated with a screw, a base with a flat blade tip and a convex portion formed on the base A replaceable blade type having a cutout portion, a handle portion having a concave portion that engages with a convex cutout portion of the blade tip portion, and a screw hole in the handle portion and the base portion of the blade tip portion. Provide scissors.

【０００５】〔作用〕刃先部のベース部と該ベース部の凸部切り欠部とが、ハンドル部に施工された刃先部の凸部切り欠部と係合する凹部と面当たりするため、刃先部のハンドル部に対するゆるみがなく、なおかつ刃先部とハンドル部との連結を強固にするものである。刃先部の交換方法は、新しい刃先部のベース部と凸部切り欠部とを、ハンドル部に施工された凹部への差し込む方法であるから極めて着脱交換が容易である。[Operation] Since the base portion of the cutting edge portion and the convex cutout portion of the base portion come into contact with the concave portion that engages with the convex cutout portion of the cutting edge portion formed on the handle portion, There is no slack in the handle of the blade, and the connection between the blade and handle is firm. The blade tip replacement method is a method in which the base portion and the convex notch portion of the new blade tip portion are inserted into the recesses formed in the handle portion, so that attachment / detachment replacement is extremely easy.

【０００６】〔実施例〕以下、図面により本考案の実施例を説明する。換え刃式ハサミは、静刃１と動刃２とをビス３とナット４（図１参照）で結合させることにより形成されている。図２と図４に示す如く、静刃１と動刃２とは基本的にはほぼ同じ構成を有し、両者とも刃先部５とハンドル部６とを有する。刃先部５にはベース部７と、その中央あたりに凸部切り欠け部９を有し、ビス孔１０を有する。ハンドル部６は刃先部５の長手方向と対接する位置に、ハンドル部凹部１２を有し、ビス孔１１を有する。[Embodiment] An embodiment of the present invention will be described below with reference to the drawings. The replaceable blade type scissors are formed by connecting the stationary blade 1 and the moving blade 2 with a screw 3 and a nut 4 (see FIG. 1). As shown in FIGS. 2 and 4, the stationary blade 1 and the moving blade 2 basically have substantially the same structure, and both have a blade tip portion 5 and a handle portion 6. The cutting edge portion 5 has a base portion 7, a convex cutout portion 9 around its center, and a screw hole 10. The handle 6 has a handle recess 12 and a screw hole 11 at a position facing the longitudinal direction of the cutting edge 5.

【０００７】刃先部５は、ベース部７とその中央あたりにベース部７の一部を、打ち抜き加工と曲げ加工を施工して形成される凸部切り欠け部９を有し、ベース部７の一側に切刃８が形成されている。図示例では凸部切り欠け部９が２個所図示されているが、凸部切り欠け部９はこの図示例に限定されることはない。例えば、図示例では凸部切り欠け部９は、切刃８側より立ち上がっているが一側だけでなく、両側より立ち上がって凸部切り欠け部９を形成してもよい。The cutting edge portion 5 has a base portion 7 and a convex cutout portion 9 formed by punching and bending a part of the base portion 7 around its center. A cutting edge 8 is formed on one side. In the illustrated example, two convex cutouts 9 are shown, but the convex cutouts 9 are not limited to this illustrated example. For example, in the illustrated example, the convex notch 9 is raised from the cutting edge 8 side, but it may be raised not only from one side but also from both sides to form the convex notch 9.

【０００８】刃先部５を保持して固定するハンドル部６には、刃先部５が有する凸部切り欠け部９と対接するハンドル部凹部１２を有する。ハンドル部凹部１２は、ハサミの回動方向に位置するため、ハサミの切断作業時にかかる刃先部５への負荷を刃先部５だけで対応するのではなく、ハンドル部凹部１２へ凸部切り欠け部９を差し込み固定することにより、刃先部５とハンドル部６とが一体化して、ハサミの切断作業負荷に対応するため、刃先部５とハンドル部６とのゆるみもない。The handle portion 6 that holds and fixes the blade edge portion 5 has a handle portion recess 12 that is in contact with the convex notch portion 9 of the blade edge portion 5. Since the handle recess 12 is located in the rotating direction of the scissors, the load applied to the blade tip 5 when cutting the scissors is not limited to the blade tip 5 alone. By inserting 9 and fixing, the cutting edge portion 5 and the handle portion 6 are integrated to cope with the cutting work load of scissors, so that there is no looseness between the cutting edge portion 5 and the handle portion 6.

【０００９】新しい刃先部５をハンドル部６に取り付けるには、凸部切り欠け部９をハンドル部６が有するハンドル部凹部１２に差し込めばよい。これらの状態を図２と図３に示す。この様に固定された静刃１と動刃２とを、ビス３とナット４とを用いて結合させればよい。刃先部５の交換は、ビス３とナット４とを外し、刃先部５をハンドル部６から抜き取り、前述の如く、新しい刃先部５をハンドル部６に差し込み、装着すればよい。In order to attach the new cutting edge portion 5 to the handle portion 6, the protrusion cutout portion 9 may be inserted into the handle portion concave portion 12 of the handle portion 6. These states are shown in FIGS. 2 and 3. The stationary blade 1 and the moving blade 2 fixed in this way may be joined by using the screw 3 and the nut 4. To replace the cutting edge portion 5, the screw 3 and the nut 4 may be removed, the cutting edge portion 5 may be removed from the handle portion 6, and the new cutting edge portion 5 may be inserted into the handle portion 6 and mounted as described above.

【００１０】刃先部５にある凸部切り欠け部９の端面１３と、ハンドル部凹部１２の端面１４とを対接することにより、ハンドル部６に対する刃先部５の長手方向のゆるみを防止する。且つ、凸部切り欠け部９の保有する弾性力により、端面１５と溝部１６とが面接触するため、刃先部５のハンドル部６に対する回動方向へのゆるみもなく、刃先部５とハンドル部６との取り付け強度も高い。By contacting the end surface 13 of the convex cutout portion 9 in the cutting edge portion 5 with the end surface 14 of the handle concave portion 12, loosening of the cutting edge portion 5 with respect to the handle portion 6 in the longitudinal direction is prevented. Moreover, since the end face 15 and the groove portion 16 are in surface contact with each other due to the elastic force possessed by the convex cutout portion 9, there is no looseness of the blade tip portion 5 in the rotational direction with respect to the handle portion 6, and the blade tip portion 5 and the handle The attachment strength with the part 6 is also high.

【００１１】〔効果〕上記の如く、本考案によるハサミは刃先部の劣化により切断作業に困難が発生したら、ビスを外して刃先部をハンドル部から抜き取り、新しい刃先部をハンドル部に差し込むだけで新しいハサミになり、極めて刃先部の交換が簡便である。刃先部が有する凸部切り欠け部を形成させるにも、打ち抜き加工と曲げ加工という一般的な手段を用いるために、量産が可能であり低価格の実現を可能にするものである。[Effect] As described above, when the scissors according to the present invention have difficulty in cutting due to deterioration of the cutting edge, remove the screw, pull out the cutting edge from the handle, and insert the new cutting edge into the handle. With new scissors, it is extremely easy to replace the cutting edge. Since the general methods such as punching and bending are used to form the convex notch part of the cutting edge part, mass production is possible and low cost can be realized.
