Description
【０００１】[0001]
本考案は木ねじ、特に、木材などの対象物に埋め込む作業を容易に行うことが できる木ねじに関する。 The present invention relates to a wood screw, and more particularly to a wood screw that can be easily embedded in an object such as wood.
【０００２】[0002]
木ねじは、木材などの壁に、額などの装飾品を吊り下げるような用途に広く利 用されている。木ねじの螺軸部の表面には、ねじ山が形成されているため、ねじ 回しなどで回転させながら、木ねじを木材などの対象物に埋め込んでゆけば、対 象物内に形成された導入孔に自然にねじが切られてゆく。このため、釘などに比 べ、より堅固に対象物内に固定されるという利点がある。 Wood screws are widely used for hanging decorative items such as foreheads on walls such as wood. Since a thread is formed on the surface of the screw shaft of a wood screw, if the wood screw is embedded in an object such as wood while being rotated by a screwdriver, etc., the introduction hole formed in the object It is naturally threaded. Therefore, it has an advantage that it is more firmly fixed in the object than nails.
【０００３】[0003]
木ねじを木材などの対象物内に埋め込む作業を行う場合、対象物内に少数のね じ山が形成された後は、ねじ回しにより木ねじを回転させる作業を行うだけで比 較的容易に木ねじを深い位置まで埋め込むことが可能である。しかし、埋め込み 作業の当初は、対象物内にねじ山が形成されていないため、木ねじの先端を対象 物内に導入させるまでに手間がかかる。特に、材質が堅い対象物の場合、なかな か木ねじの先端を対象物内に導入させることができず、作業中に、床の上に何度 も木ねじを落下させることは日常茶飯事である。このようなことを防ぐためには 、予めキリなどで対象物に予備孔を開けておく必要があり、やはり手間のかかる 作業となる。 When embedding a wood screw in an object such as wood, after a small number of screw threads are formed in the object, it is relatively easy to rotate the wood screw with a screwdriver. It is possible to embed it to a deep position. However, at the beginning of the embedding work, since the threads are not formed in the target object, it takes time to introduce the tip of the wood screw into the target object. In particular, in the case of an object made of a hard material, it is difficult to introduce the tip of the wood screw into the object, and it is common to drop the wood screw on the floor many times during work. In order to prevent such a situation, it is necessary to make a preliminary hole in the target object by drilling in advance, which is also a troublesome work.
【０００４】 そこで本考案は、木材などの対象物に埋め込む作業を容易に行うことができる 木ねじを提供することを目的とする。Therefore, an object of the present invention is to provide a wood screw that can be easily embedded in an object such as wood.
【０００５】[0005]
本考案は、底面にねじ回しの先端に嵌合する嵌合溝が形成された基部と、この 基部から底面に対してほぼ垂直な軸方向に伸び、表面に螺旋状のねじ山が形成さ れた螺軸部と、を有する木ねじにおいて、螺軸部の先端に、鋭端部と先進支持部 とからなる針状部を設け、鋭端部は、基部の底面を押圧することにより木材など の対象物内に導入孔を形成させるのに十分鋭利な形状とし、先進支持部は、基部 の底面を押圧することにより導入孔内に鋭端部に続いて導入されるような形状と し、かつ、先進支持部は、導入孔内に導入された状態において、導入孔外にある 螺軸部および基部の重量を支持することができるだけの十分な長さを有するよう にしたものである。 According to the present invention, a base portion having a fitting groove formed on the bottom surface for fitting the tip of a screwdriver, and an axial direction substantially perpendicular to the bottom surface extending from the base portion, a spiral thread is formed on the surface. In the wood screw having the screw shaft portion, a needle-shaped portion including a sharp end portion and an advanced support portion is provided at the tip of the screw shaft portion, and the sharp end portion is pressed against the bottom surface of the base portion so that the screw end The shape of the advanced support should be sharp enough to form the introduction hole in the object, and the advanced support shall be shaped so that it is introduced into the introduction hole following the sharp end by pressing the bottom surface of the base, and The advanced support portion has a sufficient length to support the weight of the screw shaft portion and the base portion outside the introduction hole when it is introduced into the introduction hole.

本考案に係る木ねじを、木材などの対象物に埋め込むには、まず、鋭端部を対 象物表面に当てた状態で底面を指で押圧し、鋭端部および先進支持部を対象物内 に埋め込む作業を行う。これは、いわば画鋲を壁に埋め込む作業と同じである。 先進支持部が導入孔内に埋め込まれると、螺軸部および基部は対象物から外れて 落下することなしに支持された状態になる。この後、ねじ回しを用いて木ねじを 回転させれば、螺軸部表面に形成されたねじ山によってねじを切りながら、更に 深く埋め込む作業を行うことができる。 To embed the wood screw according to the present invention in an object such as wood, first press the bottom face with a finger while the sharp end is in contact with the surface of the object, and then the sharp end and the advanced support part are inside the object. To embed in. This is, so to speak, the same as the work of embedding a thumbtack on a wall. When the advanced support portion is embedded in the introduction hole, the screw shaft portion and the base portion are in a supported state without falling off from the object. After that, if the wood screw is rotated by using a screwdriver, it is possible to carry out a deeper embedding operation while cutting the screw with the thread formed on the surface of the screw shaft portion.
【０００７】[0007]
以下、本考案を図示する実施例に基づいて説明する。はじめに、参考のために 従来の一般的な木ねじを図１に示す。この木ねじは、基部１０と螺軸部２０とに よって構成されている。基部１０の底面１１には、ねじ回しの先端に嵌合する嵌 合溝１２（この例は、いわゆるマイナスドライバ用の溝）が形成されている。螺 軸部２０は、基部１０から図の左方に伸びている。別言すれば、底面１１に対し てほぼ垂直な方向に伸びている。また、螺軸部２０の表面には、螺旋状のねじ山 ２１が形成されており、先端部２２は鋭利な突起を形成している。 Hereinafter, the present invention will be described based on illustrated embodiments. First, FIG. 1 shows a conventional general wood screw for reference. This wood screw is composed of a base portion 10 and a screw shaft portion 20. A fitting groove 12 (in this example, a groove for a minus driver) that is fitted to the tip of a screwdriver is formed on the bottom surface 11 of the base portion 10. The screw shaft portion 20 extends from the base portion 10 to the left in the drawing. In other words, it extends in a direction substantially perpendicular to the bottom surface 11. Further, a spiral thread 21 is formed on the surface of the screw shaft portion 20, and the tip portion 22 forms a sharp protrusion.
【０００８】 このような木ねじを、たとえば木材製の壁に埋め込む場合、先端部２２を壁に 当てながら、嵌合溝１２にねじ回しの先端を嵌め、螺軸部２０を軸回りに回転さ せながら壁内にねじを切り、より深い位置へと進めてゆくことになる。しかしな がら、最初に、螺軸部２０の先端部分を壁の中へと導入させる作業が困難である ことは、既に述べたとおりである。When such a wood screw is to be embedded in a wall made of wood, for example, the tip of a screwdriver is fitted in the fitting groove 12 while the tip 22 is being pressed against the wall, and the screw shaft 20 is rotated around the axis. While making a screw in the wall, it will proceed to a deeper position. However, as described above, it is difficult to first introduce the distal end portion of the screw shaft portion 20 into the wall.
【０００９】 本考案はこのような問題を解決するために考え出されたものである。本考案の 一実施例に係る木ねじを図２に示す。この木ねじは、図１に示す従来の木ねじと 同様に、基部１０と螺軸部２０とを有するが、更に、螺軸部２０の先端に、針状 部３０を有する点に特徴がある。この針状部３０は、いわゆる画鋲の先端部分の ような形状をしており、機能的には、鋭端部３１と先進支持部３２とによって構 成されている。ここで、鋭端部３１は、底面１１を指で押圧することにより、木 材などの対象物内に導入孔を形成させるのに十分鋭利な形状をもっている。また 、先進支持部３２は、やはり底面１１を指で押圧することにより、対象物内に形 成された導入孔内に鋭端部３１に続いて導入されるような形状をもっている。別 言すれば、鋭端部３１に続いて滑らかに挿入されるように、先進支持部３２は、 図の左から右にかけてほぼ同じ太さであるか、あるいは、ごく僅かずつ太くなっ ているにすぎない。しかも、この先進支持部３２は、対象物に形成された導入孔 内に導入された状態において、導入孔外にある螺軸部２０および基部１０の重量 を支持することができるだけの十分な長さを有する。具体的には、螺軸部２０お よび基部１０の重量が２ｇ程度のごく一般的な木ねじであれば、先進支持部３２ の長さは３〜４ｍｍ程度にすれば十分である。The present invention was devised to solve such a problem. A wood screw according to an embodiment of the present invention is shown in FIG. Similar to the conventional wood screw shown in FIG. 1, this wood screw has a base portion 10 and a screw shaft portion 20, and is further characterized in that a needle-like portion 30 is provided at the tip of the screw shaft portion 20. The needle-shaped portion 30 has a shape like a so-called tip portion of a thumbtack, and is functionally composed of a sharp end portion 31 and an advanced support portion 32. Here, the sharp end portion 31 has a shape that is sharp enough to form an introduction hole in an object such as wood by pressing the bottom surface 11 with a finger. In addition, the advanced support portion 32 has a shape such that the bottom surface 11 is also introduced into the introduction hole formed in the object following the sharp end portion 31 by pressing the bottom surface 11 with a finger. In other words, the advanced support portion 32 has almost the same thickness from the left side to the right side of the drawing, or is slightly thickened so as to be smoothly inserted following the sharp end portion 31. Only. Moreover, the advanced support portion 32 has a length sufficient to support the weight of the screw shaft portion 20 and the base portion 10 outside the introduction hole when introduced into the introduction hole formed in the object. Have. Specifically, if the weight of the screw shaft portion 20 and the base portion 10 is a very general wood screw of about 2 g, it is sufficient that the length of the advanced support portion 32 is about 3 to 4 mm.
【００１０】 このような木ねじを木材製の壁に埋め込む場合は次のようにすればよい。まず 、基部１０を指先でつまみ、鋭端部３１を壁に当てる。そして、親指の腹で底面 １１を壁に向かって押圧する。すると、鋭端部３１によって壁の中に導入孔が形 成され、鋭端部３１および先進支持部３２が、壁の中の導入孔内にめり込むこと になる。これは、ちょうど画鋲を壁に差し込む作業に似ている。先進支持部３２ のほぼ全長が壁内にめり込んだ状態になると、その状態で手を放しても、木ねじ は壁から落下することはない。これは、導入孔内の先進支持部３２によって、螺 軸部２０および基部１０の重量が支えられた状態になるからである。あとは、底 面１１に形成された嵌合溝１２に、ねじ回しの先端を嵌め、壁側に圧力を加えな がらねじ回しをゆっくりと回転させてゆけばよい。従来の木ねじと同様に、螺軸 部２０の表面に形成されたねじ山２１によって、壁内の導入孔内面にねじが切ら れながら、螺軸部２０が奥へと埋め込まれてゆく。このように、埋め込みの初期 の段階において、木ねじが落下するようなことがないため、埋め込み作業は非常 に楽になる。また、従来の木ねじのように、キリで予備孔を形成しておく必要も ない。When embedding such a wood screw in a wall made of wood, the following may be done. First, the base 10 is pinched with a fingertip, and the sharp end 31 is applied to the wall. Then, the bottom surface 11 is pressed against the wall by the belly of the thumb. Then, the sharp end portion 31 forms an introduction hole in the wall, and the sharp end portion 31 and the advanced support portion 32 are embedded in the introduction hole in the wall. This is just like inserting a pushpin into a wall. When almost all of the length of the advanced support portion 32 is set in the wall, the wood screw will not fall from the wall even if the hand is released in this state. This is because the weight of the screw shaft portion 20 and the base portion 10 is supported by the advanced support portion 32 in the introduction hole. After that, the tip of the screwdriver may be fitted into the fitting groove 12 formed on the bottom surface 11, and the screwdriver may be slowly rotated while applying pressure to the wall side. Similar to the conventional wood screw, the thread 21 formed on the surface of the screw shaft portion 20 cuts the screw on the inner surface of the introduction hole in the wall, and the screw shaft portion 20 is embedded deeply. In this way, the wood screw does not drop in the initial stage of embedding, so the embedding work becomes very easy. Further, unlike the conventional wood screw, it is not necessary to form a preliminary hole by drilling.
