Description
【０００１】[0001]
本考案は、小児が学校等で使用して安全な学童用ナイフに関する。 The present invention relates to a schoolchild knife that is safe for children to use in schools and the like.
【０００２】[0002]
従来、小児が学校等で鉛筆削り用あるいは工作用に用いているナイフは、一般 に、テーパー形状の刃体の一側縁に直線状刃面を有し、かつ刃体の先端部は鋭利 な尖先部となっているため、尖先部により、不注意により、もしくは故意に人体 を傷つけることがあり、また簡単に殺人事件を惹き起こす例も少なくない。 Conventionally, knives used by children for pencil sharpening or work at schools and the like generally have a straight blade surface on one side edge of a tapered blade, and the tip of the blade is sharp. Because of the point, the point can inadvertently or intentionally injure the human body, and there are many cases where a murder is easily caused.
【０００３】 しかし、刃体先端部を円弧状にすると、鋭利な尖先部を必要とする工作等が出 来なくなってしまう。[0005] However, if the tip of the blade body is formed in an arc shape, a work or the like that requires a sharp point cannot be provided.
【０００４】[0004]
そのため、安全で、しかも、鋭利な尖先部を必要とする工作等が出来るナイフ が望まれている。 Therefore, there is a demand for a knife that is safe and that can perform a work requiring a sharp point.
【０００５】 本考案の目的は、ナイフの先端部に尖先部を備えているにも拘わらず、妄りに 人体を傷つけたりするおそれのないナイフを提供することにある。[0005] An object of the present invention is to provide a knife that does not have a risk of hurting the human body unnecessarily despite having a sharp tip at the tip of the knife.
【０００６】[0006]
上記目的を達成するために、本考案のナイフは、刃体の下縁に直線上に延びる 刃の長さ方向の先端に、刃に連続して直線上に尖先部を設けるとともに、該尖先 部の先端と同位またはそれより先方へ突出させた先端を有する刃のない非尖先部 を、刃体の板面上の尖先部の上方に連続して設けて構成される。 In order to achieve the above object, the knife of the present invention is provided with a pointed tip that extends linearly on the lower edge of the blade body, at the tip in the length direction of the blade, and that is linearly continuous with the blade. A bladeless non-pointed tip having a tip that is the same as or protrudes beyond the tip of the tip is provided continuously above the tip on the plate surface of the blade body.
【０００７】[0007]
本考案の実施の形態を、図１及び図２を参照して説明する。 図１は、本考案のナイフの左側面図である。 An embodiment of the present invention will be described with reference to FIGS. FIG. 1 is a left side view of the knife of the present invention.
【０００８】 ナイフ(１)の刃体(２)の長さ方向の先端には、その板面上において丸味を有す る非尖先部(３)が、また非尖先部(３)の下方には、尖先部(４)が連続して設けら れている。[0008] At the longitudinal end of the blade body (2) of the knife (1), a non-pointed portion (3) having a roundness on the plate surface, and a non-pointed portion (3) of the non-pointed portion (3) are provided. A point (4) is continuously provided below.
【０００９】 尖先部(４)の先端は、非尖先部(３)の先端とほぼ同位、もしくはそれよりやや 後位にある。[0009] The tip of the point (4) is substantially at the same level as or slightly behind the tip of the non-point (3).
【００１０】 尖先部(４)の下縁には、刃体(２)の付根方向を向く直線状の刃(５)が形成され ている。[0010] A linear blade (5) is formed at the lower edge of the point (4) in the direction of the root of the blade (2).
【００１１】 図２は、図１におけるＩＩ−ＩＩ線縦断面図である。 図示のように、非尖先部(３)は厚みを有し、その下方に連続して、尖先部(４) が連続して設けられている。FIG. 2 is a vertical sectional view taken along line II-II in FIG. As shown in the drawing, the non-pointed portion (3) has a thickness, and a pointed portion (4) is continuously provided below the non-pointed portion (3).
【００１２】 刃体(２)根元は、柄(６)に取付けられている。The root of the blade body (2) is attached to the handle (6).
【００１３】 なお不使用時には、刃体(２)は図示を省略した鞘に収容されるようになってい る。When not in use, the blade body (2) is housed in a sheath (not shown).
【００１４】 本考案のナイフによれば、非尖先部(３)の先端は、尖先部(４)の先端とほぼ同 位またはその先方に突出しており、かつ非尖先部(３)の先端部は円弧状をなして いるため、このナイフを用いて、人を傷つけたり刺したりすることは出来ない。According to the knife of the present invention, the tip of the non-pointed portion (3) projects substantially the same as or ahead of the tip of the pointed portion (4), and the non-pointed portion (3). Because the tip of the knives is in an arc shape, this knife cannot be used to hurt or stab a person.
【００１５】 尖先部(４)は、非尖先部(３)の先端と同位又は後方にあるものの、図３に示す ように、ナイフをやや傾けることにより、尖先部(４)の切先を使用することが出 来、厚紙（７）の切断等に際し、非尖先部(３)が邪魔になることはない。Although the point (4) is located at the same level as or behind the tip of the non-point (3), as shown in FIG. 3, the knife (4) is cut slightly by slightly inclining the knife. The point can be used, and the non-pointed portion (3) does not become an obstacle when cutting the thick paper (7).
【００１６】 また、尖先部(４)に連続して根元にむかって直線状の刃(５)が形成されている ので、通常のナイフのように、刃(５)で鉛筆を削ったり、工作をしたりすること が出来る。Further, since a linear blade (5) is formed toward the root continuously to the point (4), a pencil is sharpened with the blade (5) like a normal knife. You can do crafts.
【００１７】 本実施例では、非尖先部(３)を円弧状としたが、先端が尖ってさえいなければ 、どの様な形状であってもよい。In this embodiment, the non-pointed portion (3) is arc-shaped, but may have any shape as long as the tip is not sharp.
【００１８】 また本考案は、折り畳み式のナイフ等にも適用できる。The present invention can also be applied to a folding knife or the like.
【００１９】[0019]
刃体の先端部に、先端が尖先部と同位もしくはそれより突出して、人体等を傷 つけるおそれのない円弧状の非尖先部を設けてあるため、安全性は高く、かつ尖 先部を利用して、多様な工作等をすることができ、便利である。 Since the tip of the blade has an arc-shaped non-pointed tip that is at the same level as or protrudes from the pointed tip and does not damage the human body, etc., the safety is high and the pointed tip is It can be used for various works, and is convenient.
