Description
【０００１】[0001]
本考案は、主として木材やプラスチック材にねじ込む木ねじであって、対象に ねじ込んだ後、緩みが生じない緩み止め機能付き木ねじに関するものでる。 The present invention mainly relates to a wood screw that is screwed into a wood or plastic material, and has a locking function that does not loosen after being screwed into an object.
【０００２】[0002]
緩み止め機能付き木ねじについては、従来から数多くの提案がなされているが 、それらは製造に手数が掛かって高価につくものが多かったり、実際のねじ込み に際して作業性の悪いものが多い。 Many proposals have been made for wood screws with a function of preventing loosening. However, many of them have been troublesome to manufacture and are expensive, and many of them have poor workability in actual screwing.
【０００３】[0003]
本考案は、上記のような従来の緩み止め機能付き木ねじの技術に鑑み、簡単な 構造で製造が容易であり、しかも、ねじ込み作業が容易な上に、締付け後、緩み が生じない緩み止め機能付き木ねじを提供することを、その課題とするものであ る。 The present invention, in view of the above-mentioned conventional technology of wood screws with a locking function, has a simple structure, is easy to manufacture, is easy to screw in, and does not loosen after tightening. It is an object of the present invention to provide a wood screw.
【０００４】[0004]
本考案は、上記課題を解決することを目的としてなされたもので、その構成は 、外周面にねじ込み用の螺糸部を設けたねじ本体において、その外周の180度離 隔した面に、ねじ本体が螺子込まれる木肉などの材料が入り込む凹部と両面の凹 部を連通させた貫通孔を設けたことを特徴とするものである。 The present invention has been made in order to solve the above-mentioned problem, and has a structure in which a screw body provided with a thread portion for screwing on an outer peripheral surface thereof has a screw formed on a surface 180 degrees apart on the outer periphery. It is characterized in that a through-hole is provided in which a concave portion in which a material such as wood meat into which the main body is screwed enters and a concave portion on both sides thereof are communicated.
【０００５】 ねじ本体の外面に対向的に形成する凹部と貫通孔を縦長に形成することにより 、凹部や貫通孔に木肉が入り易くすると共に入り込む木肉の量を多くすることに より、緩み止め効果を一層向上させることが出来る。また、対向する凹部と両凹 部を繋ぐ貫通孔は、ねじ本体の長さ方向の少なくとも２箇所に、向き（位相）を 変えて設けることもある。[0005] By forming a recess and a through-hole vertically formed on the outer surface of the screw body so as to be long, it becomes easy to enter wood into the recess and the through-hole, and the amount of wood entering the recess is increased. The stopping effect can be further improved. Further, the through-holes connecting the opposite concave portion and both concave portions may be provided in at least two positions in the length direction of the screw body with different directions (phases).
【０００６】 ねじ本体の外周面には通常の螺糸部が設けられているから、木材に対するねじ 込みは通常の木ねじと同様に円滑に行われ、強固に木肉に止着されるが、本考案 木ねじでは、ねじ込み後、木ねじの進入によって圧縮された木肉の復元力が作用 し、ねじ両面の凹部と貫通孔に復元する木肉が食い込むので、この木ねじが緩む おそれはない。[0006] Since a normal thread portion is provided on the outer peripheral surface of the screw main body, the screwing into the wood is performed smoothly like a normal wood screw and firmly fixed to the wooden meat. With the wood screw, after the screw is screwed in, the restoring force of the compressed wood is applied due to the entry of the wood screw, and the wood restored into the recesses and through holes on both sides of the screw is cut off, so there is no danger that the wood screw will be loosened.

次に、本考案の実施の形態例を図により説明する。図１は本考案の左半を断面 にした正面図、図２は図１のＡ−Ａ矢視断面図である。 Next, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a front view of a cross section of the left half of the present invention, and FIG. 2 is a cross-sectional view taken along the line AA of FIG.
【０００８】 図１において、１は先細状の一般的形態の木ねじ本体、２は該本体１の外周面 に螺旋状に形成したねじ込み用の螺糸部、3a，3bは前記螺糸部２における木ねじ 本体１に180度離隔して形成した皿状の凹部、５は前記両凹部3a，3bを連通させ た貫通孔、６は頭部４の上面に形成したねじ込み用ビットの嵌合溝で、以上によ り本考案木ねじの一例を構成する。尚、前記溝６はプラス型でもマイナス型でも よい。In FIG. 1, reference numeral 1 denotes a wood screw main body having a tapered general form, reference numeral 2 denotes a screw thread portion spirally formed on the outer peripheral surface of the main body 1, and reference numerals 3 a and 3 b denote the screw thread portion 2. A wood-shaped screw-shaped recess formed in the main body 1 at 180 degrees, a through-hole 5 communicating the two recesses 3a and 3b, and a fitting groove 6 for a screw-in bit formed on the upper surface of the head 4. The above constitutes an example of the wood screw of the present invention. Incidentally, the groove 6 may be a plus type or a minus type.
【０００９】 この木ねじは、まず、螺糸部２の先端をねじ込み箇所に当てがい、溝６にドラ イバ等の締付具のビットを嵌め込んで捩じり込みを開始する。螺糸部２の作用に よる捩じり込み進入が終わると、この木ねじの進入によって圧縮された木肉は、 凹部3a，3bに対向した部位の木肉が復元力で戻り乍ら当該凹部3a，3bに入り込み 、更に進んで貫通孔５の中まで進入する。In this wood screw, first, the tip of the thread portion 2 is applied to a screwed portion, and a bit of a fastener such as a driver is fitted into the groove 6 to start screwing. When the entry of the screw by the action of the thread portion 2 is completed, the compressed wood due to the entry of the wood screw returns to the recess 3a while the portion of the wood facing the recesses 3a and 3b returns with a restoring force. , 3b and further into the through hole 5.
【００１０】 このように、木材にねじ込まれた本考案木ねじは、そのねじ込み進入により拡 開圧縮された木肉がその復元力により前記凹部3a，3bの貫通孔５の空間を埋め、 結果的に凹部3a，3b、貫通孔５に入り込んだ木肉が回り止めとして作用すること になるので、ねじ込み後、本考案木ねじに緩みの生じるおそれはおよそ皆無であ る。As described above, in the wood screw of the present invention screwed into the wood, the wood meat expanded and compressed by the screwing approach fills the space of the through holes 5 of the recesses 3a and 3b by the restoring force. Since the wooden meat that has entered the recesses 3a and 3b and the through hole 5 acts as a detent, there is almost no possibility that the wooden screw of the present invention will be loosened after screwing.
【００１１】 本考案では、木ねじ本体の周上で対向した凹部3a，3bと貫通孔５を、木ねじ本 体１の長さ方向で、２箇所又はそれ以上設けることがある。凹部3a，3bと貫通孔 ５を木ねじ本体１に何箇所設けるかは、木ねじの長さ，太さなどにより、適宜設 定すればよい。また、凹部3a，3bや貫通孔５は、断面を円形とすのほか、縦長又 は横長の長円形、或は、斜めの長円形の断面形状とすることもある。In the present invention, two or more recesses 3 a and 3 b and a through hole 5 facing each other on the periphery of the wood screw main body may be provided in the length direction of the wood screw main body 1. The number of the recesses 3a and 3b and the number of through holes 5 provided in the wood screw main body 1 may be appropriately set according to the length and thickness of the wood screw. The recesses 3a, 3b and the through-hole 5 may have a vertical or horizontal oval or oblique oval cross section in addition to a circular cross section.
【００１２】 上記の実施形態の例は、本考案木ねじを木材にねじ込む例についてのものであ るが、本考案木ねじは、プラスチック材へのねじ込みに適用しても木材へのねじ 込みと同等の効果が得られる。[0012] The example of the above embodiment relates to an example in which the wood screw of the present invention is screwed into wood, but the wood screw of the present invention is equivalent to screwing into wood even when applied to screwing into a plastic material. The effect is obtained.
【００１３】[0013]
本考案木ねじは上述のとおりであって、外周面にねじ込み用の螺糸部を設けた ねじ本体において、その外周の180度離隔した面に、ねじ本体が螺子込まれる木 肉などの材料が入り込む凹部と両面の凹部を連通させた貫通孔を設けたから、木 材にねじ込んで取付けると、木ねじ取付部分の木肉の復元力により、木ねじの外 面に設けた凹部や貫通孔に対応する部位の木肉が凹部や貫通孔に入り込むので、 緩みが生じて脱落するおそれはないし、そのねじ込み作業も通常の木ねじと大差 はなく簡易に行うことができる。特に、本考案木ねじは、構造が簡単であるから 、緩み止め機能を持つ木ねじを容易且つ低廉に作製提供することができる。 The wood screw of the present invention is as described above, and in a screw body provided with a screw thread portion for screwing on the outer peripheral surface, a material such as wood meat into which the screw body is screwed enters into a surface 180 degrees apart on the outer periphery thereof. Since a through hole is provided that connects the recess and the recess on both sides, when screwed into a wooden material, the restoring force of the wood attached to the wood screw causes the recessed portion on the outer surface of the wood screw to correspond to the through hole. Since the wooden meat enters the recesses and through holes, there is no risk of loosening and falling off, and the screwing operation can be performed easily without much difference from ordinary wood screws. In particular, since the wood screw of the present invention has a simple structure, a wood screw having a locking function can be easily and inexpensively manufactured and provided.
