Abstract
Description
本発明は、ねじ込んだ後、緩まない様にされた、緩み防止ネジに関する。特に、眼鏡のフレームと部品、又は部品同士の連結又は締結に使用される物に関する。 The present invention relates to a loosening prevention screw that is prevented from loosening after being screwed. In particular, the present invention relates to an object used for connecting or fastening eyeglass frames and parts or parts.
従来、眼鏡の部品として、丁番部やリムロックその他に使用されるネジに於いては、その寸法が小さい上、使用している内にだんだん緩んできてしまっていく事が多かった。そこで、その様な緩みを防止用のネジとして、色んなものが提案されてきている。そして、その中で、例えば特開平8−303444の様な緩み防止案が提案されている。 Conventionally, screws used for hinge parts, rim locks, and the like as spectacle parts are small in size and often loosen gradually during use. Accordingly, various screws have been proposed as screws for preventing such loosening. Among them, for example, a loosening prevention plan such as that disclosed in JP-A-8-303444 has been proposed.
しかしながら、上記特開平8−303444の様に、ネジ山頂部に爪を形成すると、ネジ山頂部以上に爪が突出し、その部分が弱くなる為ネジに焼入れを行わなければ、爪が直ぐに折れてしまい、用を成さなくなってしまった。特に眼鏡の丁番部に於いては、何万回と開閉を繰り返す事によりその爪の部分の耐久性は無く、致命的な事故に繋がってしまう事となる。 However, if the claw is formed at the top of the screw thread as in the above-mentioned JP-A-8-303444, the claw protrudes beyond the top of the screw thread, and the part becomes weak. I'm no longer using it. In particular, in the hinge part of the glasses, by repeating the opening and closing tens of thousands of times, there is no durability of the nail part, leading to a fatal accident.
そこで本発明に於いては、先ず、ネジの切欠き部のネジ軸横断面への投影形状が、略三角形で、その頂点三点を直線で結んだ形状がほぼ直角不等辺三角形であり、その直角不等辺三角形の直角又は鈍角のどちらか一つの頂点が戻り側ネジ山頂部に、他方は谷底部にある様にされ、そして、残りの鋭角部の頂点が押し込み側山頂部にある様に形成され、そして、その様にして形成された前記切欠き部を少なくとも一箇所以上、一回転部に有する様に形成する事により上記課題の解決を図った。 Therefore, in the present invention, first, the projected shape of the notch of the screw onto the screw shaft cross section is a substantially triangular shape, and the shape formed by connecting the three vertices with a straight line is a substantially right-angled triangle. Either right angle or obtuse angle of right-angled unequal triangle is formed so that the top of the return thread is at the top, the other is at the bottom of the valley, and the rest of the acute angle is at the top of the indentation And the above-mentioned subject was solved by forming so that the notch part formed in that way had at least one or more places in one rotation part.
次に、前記山頂部切欠き部近辺の戻り側頂部が、そのネジ本来の角度よりも上下どちらかに僅かに曲げるように形成し更なる効果を図った。Next, the return side apex in the vicinity of the peak notch is formed so as to be slightly bent up or down from the original angle of the screw for further effect.
そして、更に、前記切欠き部が連続して上下に少なくとも二箇所以上設けられた部分が少なくとも一箇所以上有するに形成した。 Further, the cutout portion is formed so as to have at least one or more portions that are continuously provided at least two locations in the vertical direction.
本発明により、ネジの締め付けの際には、スムーズに回転し進入し、締め付け後は緩み防止効果がしっかり効いて、丁番の回転試験に於いても、充分な摩擦力により緩み止め効果が得られた。 According to the present invention, when the screw is tightened, it smoothly rotates and enters, and after tightening, the effect of preventing looseness is effective, and even in the rotation test of the hinge, the effect of preventing loosening is obtained with sufficient frictional force. It was.
以下図による実施例により本発明の最良の形態を説明するが、本発明は以下の実施例図や説明文により限定されるものではなく、特許請求の範囲により限定されるべきものである。 The best mode of the present invention will be described below with reference to the drawings. However, the present invention should not be limited by the following drawings or descriptions but should be limited by the claims.
図1は説明用のネジの正面図で、図2及び3は、そのA−A断面図であり、図4及び5は図2,3の要部拡大図である。図2,3の様に、ネジ10の切欠き部20のネジ軸横断面への投影形状が略三角形又は略弓形で、その頂点X、Y、Z、の三点を直線で結んだ形状が、図4、5の様にほぼ直角不等辺三角形30,31、である様に加工する。 1 is a front view of an explanatory screw, FIGS. 2 and 3 are AA cross-sectional views thereof, and FIGS. 4 and 5 are enlarged views of main portions of FIGS. As shown in FIGS. 2 and 3, the projected shape of the
そして図4は、直角不等辺三角形30の鈍角部の頂点Zを戻り側ネジ山頂部40に、直角部Xを谷底部42にある様にし、そして残りの鋭角部の頂点Yが押し込み側ネジ山頂部41にあるように形成した状態を表している。 And FIG. 4 shows that the obtuse angle apex Z of the right-angled
又、図3とその要部拡大図の図5の様に、直角不等辺三角形31の直角部の頂点Z2を戻り側ネジ山頂部40a上に、鈍角部の頂点X2を谷底部42aにある様にし、そして、残りの鋭角部頂点Y2を押し込み側ネジ山頂部41a上に置く様に加工しても良い。Further, as shown in FIG. 3 and FIG. 5 of an enlarged view of the main part, the vertex Z2 of the right angle portion of the right-angled
そうする事により、矢印T1〜T4の方に押し込む場合、戻り側ネジ山頂部40,40aは邪魔にはならず、又、押し込み側ネジ山頂部41,41aも勿論、比較的緩やかな鈍角になっているので、締め付け・押し込みの邪魔にはならない。 By doing so, when pushing in the directions of the arrows T1 to T4, the return-
しかし、ネジが緩み戻ろうとする場合は、戻り側ネジ山頂部40,40a,の角度は90度に等しいか小さいので、先端部がナット側溝(図示無し)に喰い込み、緩む事がない。そして、押し込み側ネジ山頂部41,41aも直線で切ったような切欠き部を形成してあるので、多少エッジが立って、戻り防止に一役果たす事となる。 However, when the screw is about to loosen back, the angle of the return-
図6,7は本発明の緩み防止ネジを作る場合の説明図であり、先ず図6の様に、ネジ基材にプレスにより略三角形の切欠き部21を形成し、それから転造ダイスでネジ山・溝を形成しても良く、又、転造ダイスでネジ山・溝を形成した後、ダイスで図7の様に、切削、プレス等で前記略三角形部分を削り取っても良い。 FIGS. 6 and 7 are explanatory diagrams for making the loosening prevention screw of the present invention. First, as shown in FIG. 6, a substantially
又、図8の様に切欠き部が一箇所20でも良く、図9の様に上下に二箇所20a以上連続して設けられても良く、又完全ネジ部のみならず不完全ネジ部に設けても良い。 Moreover, the notch part may be one
そして次に、図10の様に、山頂部切欠き部近辺の戻り側ネジ山頂部40Cが、そのネジ本来の角度よりも上下40d,40eの様にどちらかに僅かに曲げられた状態に形成されても良く、こうする事により更に緩み防止効果が倍増した。 Then, as shown in FIG. 10, the return-side thread crest 40C in the vicinity of the crest notch is formed in a state where it is slightly bent to either the top or
そして、図11は本発明のネジを眼鏡に使用する場合の眼鏡の斜視図であり、丁番部50,51がもっとも緩み易い箇所であるが、しっかり緩み防止効果があった。又、他にもリムロック部分、パッド部分(図示無し)等にも使用する事が可能である。 FIG. 11 is a perspective view of eyeglasses when the screw of the present invention is used for eyeglasses. The
又、他の分野のネジにも使用出来、その応用範囲は広い。 It can also be used for screws in other fields, and its application range is wide.
