The base portions 22 and 23 are fixed to the back side of the cover portions 18 and 19 through the mounting holes 47 and 48 by the fixing piece portions 51 and 52, and the mounting holes 49 and 49 are fixed by the fixing piece portions 53 and 54. It is fixed to the back side of the cover parts 18 and 19 through 50.
As shown in FIG. 1, the blades 24 and 25 are erected from the inner ends of the base portions 22 and 23 in the width direction along the length directions of the notches 45 and 46, respectively. As shown to (a)-(c), it has a pair of contact surface 55,56 orthogonal to the rotation direction E in the whole area along the length direction of the said blade bodies 24,25.

また、傾斜面部２６，２７は、図１に示すように、上記刃体２４，２５の長さ方向に沿って全域に設けられ、上記一対の刃体２４，２５の幅方向先端部は、図３（ａ）に示すように、回動方向Ｅに対して同一の傾斜角αにより斜めに切削されて形成されている。
また、傾斜面部２６，２７は、図３（ａ）に示すように、紙等の厚さ寸法の小さい被切断物を切断する際には、上記一対の傾斜面部２６，２７の先端縁３２，３３が互いに摺接して、図１に示すように、把持部１１，１２の回動操作に伴って、上記先端縁３２，３３が互いに摺接する摺接部Ｆを後端部側から先端部側に移動させることによって切断するように構成されている。 Further, as shown in FIG. 1, the inclined surface portions 26 and 27 are provided over the entire area along the length direction of the blade bodies 24 and 25, and the front ends in the width direction of the pair of blade bodies 24 and 25 are illustrated in FIG. As shown in FIG. 3 (a), it is formed by being obliquely cut with respect to the rotation direction E at the same inclination angle α.
In addition, as shown in FIG. 3A, the inclined surface portions 26 and 27 are formed at the leading edges 32 and 27 of the pair of inclined surface portions 26 and 27 when cutting an object having a small thickness such as paper. 33 slidably contact each other, and as shown in FIG. 1, as the gripping portions 11 and 12 rotate, the slidable contact portion F where the leading edges 32 and 33 slidably contact each other is changed from the rear end side to the front end side. It is comprised so that it may cut | disconnect by moving to.

また、上記切断部１３，１４が閉じられた場合には、図２及び図４に示すように、上記刃体２４，２５の長さ方向先端部２８，２９において、上記一対の傾斜面部２６，２７が互いに係合するように構成されている。
この場合、図４に示すように、上記傾斜面部２６，２７は、回動方向Ｅに対して同一の傾斜角αを有し、上記刃体２４，２５の厚さ方向内端部から外端部に傾斜するように形成され、また、図２に示すように、上記一対のハサミ構成部材１５，１６は、上記刃体２４，２５の長さ方向先端部２８，２９における上記一対の傾斜面部２６，２７の係合のみにより互いに閉じた状態を保持するように構成されている。 When the cutting portions 13 and 14 are closed, as shown in FIGS. 2 and 4, the pair of inclined surface portions 26 and 29 at the longitudinal end portions 28 and 29 of the blade bodies 24 and 25. 27 are configured to engage with each other.
In this case, as shown in FIG. 4, the inclined surfaces 26 and 27 have the same inclination angle α with respect to the rotation direction E, and the outer ends of the blade bodies 24 and 25 from the inner ends in the thickness direction. As shown in FIG. 2, the pair of scissors constituting members 15 and 16 are formed of the pair of inclined surface portions at the longitudinal end portions 28 and 29 of the blade bodies 24 and 25, respectively. It is configured to hold the closed state only by the engagement of 26 and 27.

また、把持部１１，１２の操作により、図４に示すような上記切断部１３，１４を閉じた状態から図３（ｃ）に示すような開いた状態に移行させる場合において、回動方向Ｅに対しての上記傾斜角αが０度に近づく程、図４に示すような係合状態から、極めて小さな力により図３（ｃ）に示すような開放状態に簡単に移行し易く、回動方向Ｅに対しての上記傾斜角αが９０度に近づく程、上記一対の傾斜面部２６，２７の先端縁３２，３３が互いに乗り上げ難くなることから極めて大きな力でなければ図３（ｃ）に示すような開放状態への移行が難しい。
従って、上記一対の傾斜面部２６，２７の上記傾斜角αは、一定の力で把持部１１，１２を開かないと刃体２４，２５は開かないように形成されていると共に、一定の力で把持部１１，１２を開いた場合には刃体２４，２５が開くように形成されている。
例えば、本実施例の場合、図３（ａ）に示すように、上記傾斜角αは略２５度に形成されている。 Further, in the case of moving the cutting parts 13 and 14 as shown in FIG. 4 from the closed state to the opened state as shown in FIG. As the inclination angle α with respect to the angle approaches 0 degree, the engagement state as shown in FIG. 4 is easily shifted to the open state as shown in FIG. As the inclination angle α with respect to the direction E approaches 90 degrees, the tip edges 32 and 33 of the pair of inclined surface portions 26 and 27 become difficult to ride on each other. It is difficult to shift to the open state as shown.
Accordingly, the inclination angle α of the pair of inclined surface portions 26 and 27 is formed so that the blade bodies 24 and 25 do not open unless the gripping portions 11 and 12 are opened with a constant force. When the gripping portions 11 and 12 are opened, the blade bodies 24 and 25 are formed to open.
For example, in the present embodiment, as shown in FIG. 3A, the inclination angle α is formed to be approximately 25 degrees.

以下、本実施例の作用について説明する。
紙等の厚さ寸法の小さい被切断物を切断する場合には、先ず、図２に示すように、刃体２４，２５の長さ方向先端部２８，２９において、一対の傾斜面部２６，２７が互いに係合して閉じている状態において、ハサミ構成部材１５，１６の指通し孔部３０，３１に指を挿通させてから、一対の傾斜面部２６，２７の係合状態を解除して一対のハサミ構成部材１５，１６を開くように把持部１１，１２を回動操作する。
この場合、図４に示すように、上記一対の傾斜面部２６，２７は、刃体２４，２５の厚さ方向内端部から外端部に傾斜する傾斜する回動方向Ｅに対して傾斜角αを有して互いに係合していることから、一定の力で把持部１１，１２を開かないと刃体２４，２５は開かない。
そして、一定の力で把持部１１，１２を操作することにより、上記刃体２４，２５の長さ方向先端部２８，２９において係合している一対の傾斜面部２６，２７の係合状態を解除して、図３（ａ）に示すように、上記一対の傾斜面部２６，２７の先端縁３２，３３を互いに乗り上げさせて摺接するように移行させてから、先端縁３２，３３が互いに摺接する摺接部Ｆを上記ハサミ構成部材１５，１６先端部側から後端部側に摺動させながら、上記刃体２４，２５を開いていく。
このように、一定の力で把持部１１，１２を開かないと刃体２４，２５が開かないため、安全性の高い安全ハサミ１０を提供することができる。 Hereinafter, the operation of the present embodiment will be described.
When cutting a workpiece having a small thickness such as paper, first, as shown in FIG. 2, a pair of inclined surface portions 26, 27 are formed at the longitudinal ends 28, 29 of the blade bodies 24, 25. Are engaged with each other and closed, the fingers are inserted into the finger holes 30 and 31 of the scissors constituting members 15 and 16, and then the pair of inclined surfaces 26 and 27 are released to engage with each other. The gripping portions 11 and 12 are rotated so as to open the scissors constituting members 15 and 16.
In this case, as shown in FIG. 4, the pair of inclined surface portions 26, 27 are inclined with respect to a rotation direction E that is inclined from the inner end portion in the thickness direction of the blade bodies 24, 25 to the outer end portion. Since they have α and are engaged with each other, the blades 24 and 25 cannot be opened unless the gripping portions 11 and 12 are opened with a constant force.
Then, by operating the gripping portions 11 and 12 with a constant force, the engagement state of the pair of inclined surface portions 26 and 27 engaged with the longitudinal end portions 28 and 29 of the blade bodies 24 and 25 is changed. As shown in FIG. 3 (a), the tip edges 32, 33 of the pair of inclined surface portions 26, 27 are moved so as to ride on each other and come into sliding contact with each other, and then the tip edges 32, 33 slide on each other. The blade bodies 24 and 25 are opened while sliding the sliding contact portion F in contact with the scissors constituting members 15 and 16 from the front end side to the rear end side.
Thus, since the blades 24 and 25 are not opened unless the gripping portions 11 and 12 are opened with a constant force, the highly safe scissors 10 can be provided.

そして、紙等の厚さ寸法の小さい被切断物を切断する際には、図３（ａ）に示すように、上記ハサミ構成部材１３，１４の回動方向Ｅに対して直角であって、上記一対の刃体２４，２５に沿うように紙等を配置した後に、上記把持部１１，１２の操作により、摺接部Ｆを上記ハサミ構成部材１５，１６の後端部側から先端部側に摺動させる。
この場合、上記一対の刃体２４，２５の長さ方向に沿って、図３（ａ）に示すような一対の傾斜面部２６，２７の先端縁３２，３３が互いに摺接部Ｆにおいて摺接しながら刃体２４，２５の先端側へ移動することから、紙等の厚さ寸法の小さい被切断物を容易に切断することができる。 Then, when cutting an object having a small thickness such as paper, as shown in FIG. 3 (a), it is perpendicular to the rotational direction E of the scissors constituting members 13, 14, After arranging paper or the like along the pair of blades 24 and 25, the sliding contact portion F is moved from the rear end portion side to the front end portion side by the operation of the gripping portions 11 and 12. To slide.
In this case, along the length direction of the pair of blade bodies 24, 25, the tip edges 32, 33 of the pair of inclined surface portions 26, 27 as shown in FIG. However, since it moves to the front end side of the blade bodies 24 and 25, a to-be-cut object with small thickness dimensions, such as paper, can be cut easily.

また、このように紙等を切断する際に、仮に、不注意や誤って指等を一対の刃体２４，２５の間に挟んだ場合であっても、指等は厚さ寸法が大きいことから、図３（ａ）に示すような摺接部Ｆが指等を挟み込む前に、図３（ｂ）に示すような刃体２４，２５の当接面５５，５６が指等に当接して、上記刃体２４，２５の先端縁３２，３３は指等が挟み込まれた部位においては摺接しないので、厚さ寸法は大きい指等が上記摺接部Ｆに挟み込まれることにより負傷を負う危険性は少ない。   Further, when cutting paper or the like in this way, even if the finger or the like is inadvertently or mistakenly sandwiched between the pair of blades 24 and 25, the finger or the like has a large thickness dimension. Therefore, before the sliding contact portion F as shown in FIG. 3A sandwiches the finger or the like, the contact surfaces 55 and 56 of the blade bodies 24 and 25 as shown in FIG. The tip edges 32 and 33 of the blades 24 and 25 are not slid in contact with the finger or the like, so that a finger having a large thickness is injured when the finger or the like having a large thickness is caught in the slidable contact portion F. There is little danger.

また、被切断物を切断した後に、図２に示すように、上記切断部１３，１４を閉じた状態で固定する場合には、上記刃体２４，２５の長さ方向先端部２８，２９は、図４に示すように、上記刃体２４，２５の厚さ方向内端部から外端部に傾斜する同一の傾斜角αを有しているので、上記切断部１５，１６が閉じられた場合には、図３（ａ）に示すような上記刃体２４，２５の先端縁３２，３３が互いに摺接している状態から上記刃体２４，２５の長さ方向先端部２８，２９において一対の傾斜面部２６，２７が互いに係合する状態に移行し易く、安全ハサミ１０の切断部１３，１４を容易に閉じることができる。
また、安全ハサミ１０の切断部１３，１４を閉じた後においては、上記刃体２４，２５の長さ方向先端部において上記一対の傾斜面部２６，２７が互いに同一の傾斜角αが当接するように係合して上記一対のハサミ構成部材１５，１６が互いに閉じた状態を保持するので、安定した状態で上記一対のハサミ構成部材１５，１６の閉じた状態を保持できる。
また、一定の力で把持部１１，１２を操作しなければ、一対の傾斜面部２６，２７の係合状態を解除できないことから、一定の力で把持部１１，１２を開かないと刃体２４，２５が開かない、より安全性の高い安全ハサミ１０を提供することができる。 In addition, after cutting the object to be cut, as shown in FIG. 2, when the cutting parts 13 and 14 are fixed in a closed state, the longitudinal ends 28 and 29 of the blade bodies 24 and 25 are As shown in FIG. 4, since the blades 24 and 25 have the same inclination angle α inclined from the inner end to the outer end in the thickness direction, the cutting parts 15 and 16 are closed. In such a case, a pair of blades 24 and 25 at the front end portions 28 and 29 in the lengthwise direction from the state in which the tip edges 32 and 33 of the blades 24 and 25 are in sliding contact with each other as shown in FIG. It is easy to shift to a state in which the inclined surface portions 26 and 27 are engaged with each other, and the cutting portions 13 and 14 of the safety scissors 10 can be easily closed.
In addition, after the cutting portions 13 and 14 of the safety scissors 10 are closed, the pair of inclined surface portions 26 and 27 are in contact with each other at the same inclination angle α at the longitudinal ends of the blade bodies 24 and 25. Since the pair of scissors constituting members 15 and 16 are engaged with each other, the closed state of the pair of scissors constituting members 15 and 16 can be maintained in a stable state.
Further, since the engaged state of the pair of inclined surface portions 26 and 27 cannot be released unless the grip portions 11 and 12 are operated with a constant force, the blade body 24 must be opened unless the grip portions 11 and 12 are opened with a constant force. , 25 cannot be opened, and the safety scissors 10 with higher safety can be provided.

また、図１及び図２に示すように、本考案に係る安全ハサミ１０のカバー部１８，１９は、基部２２，２３の表面を被覆すると共に幅方向外端部を突状部３７，３８により被覆し、上記刃体２４，２５は、切り欠き部４５，４６に沿って上記カバー部１８，１９の裏面側に固定されているので、上記刃体２４，２５の幅方向先端部に形成されている一対の傾斜面部２６，２７の鋭利な先端縁３２，３３は、外部からは触れ難く、負傷を負う危険性が少ない安全性の高い安全ハサミ１０を提供することができる。
また、上記カバー部１８，１９の先端部は、外側面に曲面を有する凸部３９，４０が形成されているので、鋭利な刃体２４，２５の幅方向先端縁３２，３３を外部から触れ難く、不注意や誤って先端部前方へ上記安全ハサミ１０を突き出してしまった場合においても、負傷を負う危険性が少ない安全性の高い安全ハサミ１０を提供することができる。
また、本考案に係る安全ハサミ１０は、刃部２０，２１以外の構成要素である、把持部１１，１２、カバー部１８，１９、及び支軸部１７がプラスチック素材により形成されると共に夫々の端部は丸みを帯びて形成されているため、より安全性の高い安全ハサミ１０を提供することができる。 As shown in FIGS. 1 and 2, the cover portions 18 and 19 of the safety scissors 10 according to the present invention cover the surfaces of the base portions 22 and 23, and the widthwise outer end portions thereof by projecting portions 37 and 38.
