ところで以上の構造の埋め込みナットにあっては、前記筒体の他にナット本 体を必要とし、それだけ部品点数が増大するし、しかも前記筒体の一端に前記ナ ット本体を溶接などにより更に固着する必要があり、従って製造コストが高くな る不具合がある。 By the way, in the embedded nut having the above structure, the nut main body is required in addition to the tubular body, and the number of parts is increased accordingly, and further, the nut body is further welded to one end of the tubular body. There is a problem that it needs to be fixed and thus the manufacturing cost is high.
【０００４】 本考案は以上の実情に鑑みて開発したもので、目的とするところは部品点数 少なくして、従来よりも安価で軽量の埋め込みナットを提供するにある。The present invention has been developed in view of the above circumstances, and an object thereof is to provide an embedded nut that is cheaper and lighter than conventional ones by reducing the number of parts.

しかして本考案は、所定間隔開けて長さ方向に延びる複数のスリット２と、 該スリット２の長さ方向一側方において該スリット２の長さ方向に対してほぼ直 交する方向に延びるねじ山列４とを設けた平板状の金属板１を、前記ねじ山列４ が内周面に位置して且つ周方向に連続するように円筒状に曲成して、前記スリッ ト２間に径方向外方に座屈可能な複数の座屈部６を設けたことを特徴とするもの である。 Therefore, the present invention provides a plurality of slits 2 extending in the length direction at predetermined intervals, and a screw extending in a direction substantially perpendicular to the length direction of the slit 2 on one side in the length direction of the slit 2. The flat metal plate 1 provided with the mountain row 4 is bent into a cylindrical shape so that the thread mountain 4 is located on the inner peripheral surface and is continuous in the circumferential direction, and is provided between the slits 2. It is characterized in that a plurality of buckling portions 6 capable of buckling in the radial direction are provided.
【０００６】[0006]
本考案によれば、ねじ山列４とスリット２をプレス成形などにより形成した 平板状の金属板１を円筒状に曲げるだけの極めて簡単な加工で形成することが出 来、従って製造コストを安価とすることが出来るし、また重量も軽く出来る。 According to the present invention, it is possible to form the flat metal plate 1 in which the thread row 4 and the slit 2 are formed by press molding or the like by a very simple process such as bending into a cylindrical shape, so that the manufacturing cost is low. And the weight can be reduced.
【０００７】[0007]
本考案にかかる埋め込みナットは、平面視長方形とした平板状の金属板１か ら成るのであって、図に示す実施例では、この金属板１に、該金属板１の長さ方 向に延びる複数のスリット２をプレス成形により形成すると共に、この金属板１ の両側部を該金属板１の長さ方向に一部切欠いて、該金属板１の両側部に、前記 スリット２の幅の二分の一の幅から成る切欠凹部３ａ・３ｂを同じくプレス成形 により形成する。 The embedded nut according to the present invention comprises a flat plate-shaped metal plate 1 having a rectangular shape in plan view. In the embodiment shown in the drawings, the embedded nut extends in the lengthwise direction of the metal plate 1. A plurality of slits 2 are formed by press molding, and both side portions of the metal plate 1 are partially cut out in the longitudinal direction of the metal plate 1 so that the width of the slit 2 is divided into two parts on both side portions of the metal plate 1. The notch recesses 3a and 3b each having one width are also formed by press molding.
【０００８】 また前記金属板１における前記スリット２の長さ方向一側方に、該スリット ２の長さ方向に対してほぼ直交する方向に延びる複数の突条４０から成るねじ山 列４をプレス成形により突設する一方、該金属板１における前記スリット２の長 さ方向他側方に、該金属板１を一部切り起こして前記ねじ山列４の突設方向とは 反対方向に突出する山型の係合片５を突設する。Further, a thread row 4 composed of a plurality of ridges 40 extending in a direction substantially orthogonal to the length direction of the slit 2 is pressed to one side in the length direction of the slit 2 on the metal plate 1. While protruding by molding, the metal plate 1 is partially cut and raised to the other side in the length direction of the slit 2 in the metal plate 1 and protrudes in a direction opposite to the protruding direction of the thread row 4. A mountain-shaped engaging piece 5 is provided so as to project.
【０００９】 しかしてかかる金属板１を、前記係合片５が外周面に位置し、また前記ねじ 山列４が内周面に位置して且つ周方向に連続するように円筒状に曲成すると共に 、前記両切欠凹部３ａ・３ｂを突き合わせて、円筒体１０を形成し、該円筒体１ ０における前記スリット２並びに前記切欠凹部３ａ・３ｂ間に径方向外方に座屈 可能な複数の座屈部６を設けるのである。Thus, the metal plate 1 is bent into a cylindrical shape such that the engagement piece 5 is located on the outer peripheral surface and the thread row 4 is located on the inner peripheral surface and is continuous in the circumferential direction. At the same time, the notched recesses 3a and 3b are butted against each other to form a cylindrical body 10, and a plurality of radially outwardly buckled between the slit 2 and the notched recesses 3a and 3b of the cylindrical body 10 are formed. The buckling portion 6 is provided.
【００１０】 以上の埋め込みナットは、図３に示すように、例えば家屋の側壁７に形成し た挿通孔７０に挿通して、前記係合片５を前記挿通孔７０の内周面に係合させる と共に、前記円筒体１０における前記ねじ山列４形成部位並びに前記座屈部６を 前記側壁７の内側面よりも内方に突出させる。As shown in FIG. 3, the embedded nut described above is inserted into, for example, an insertion hole 70 formed in a side wall 7 of a house, and the engagement piece 5 is engaged with an inner peripheral surface of the insertion hole 70. At the same time, the screw thread row 4 forming portion and the buckling portion 6 of the cylindrical body 10 are made to protrude inward from the inner side surface of the side wall 7.
【００１１】 そして例えばフック等の被取付部材８０を装着したボルト８を、前記円筒体 １０に挿通して、その挿通端部を前記ねじ山列４で構成される雌ねじに螺締する のであり、該ボルト８の螺締に伴ってボルト８の頭部８１が前記側壁７の外側面 に当接した段階から、該ボルト８の締め付けトルクにより、前記円筒体１０にお ける前記ねじ山列４の形成部位が前記頭部８１側に移動して、前記座屈部６が、 その長さ方向途中からくの字状に折れて径方向外方に座屈し、前記側壁７の内側 面における前記挿通孔７０の開口部周りに圧接するのである。Then, for example, the bolt 8 to which the attached member 80 such as a hook is attached is inserted into the cylindrical body 10, and the insertion end portion is screwed into the female screw formed by the thread row 4. From the stage in which the head 81 of the bolt 8 comes into contact with the outer surface of the side wall 7 as the bolt 8 is screwed, the tightening torque of the bolt 8 causes The forming portion moves to the head 81 side, the buckling portion 6 folds in a dogleg shape from the middle in the length direction and buckles radially outward, and the insertion portion on the inner surface of the side wall 7 is inserted. The pressure is applied around the opening of the hole 70.
【００１２】 斯くして前記埋め込みナットは前記側壁７の挿通孔７０内に固定されると共 に、該埋め込みナットに螺着した前記ボルト８で固定される被取付部材８０が前 記側壁７に安定的に固定されるのである。Thus, the embedded nut is fixed in the insertion hole 70 of the side wall 7, and at the same time, the attached member 80 fixed by the bolt 8 screwed to the embedded nut is attached to the side wall 7. It is fixed stably.
【００１３】 以上の実施例では、前記座屈部６を前記側壁７の内側面における前記挿通孔 ７０の開口部周りに圧接させるようにしたが、前記挿通孔７０の全長が、前記円 筒体１０の全長よりも長い場合には、前記座屈部６を前記挿通孔７０の内周面に 圧接させてもよい。In the above embodiment, the buckling portion 6 is pressed against the inner surface of the side wall 7 around the opening of the insertion hole 70. However, the entire length of the insertion hole 70 is the cylindrical body. When it is longer than the total length of 10, the buckling portion 6 may be pressed against the inner peripheral surface of the insertion hole 70.
【００１４】 また以上の実施例では、前記スリット２及び前記座屈部６を前記円筒体１０ の軸方向に平行に延びるように設けたが、図４で概略的に示すように、前記スリ ット２及び座屈部６を前記円筒体１０の軸方向に対し傾斜させてもよい。Further, in the above embodiment, the slit 2 and the buckling portion 6 are provided so as to extend parallel to the axial direction of the cylindrical body 10. However, as shown schematically in FIG. The belt 2 and the buckling portion 6 may be inclined with respect to the axial direction of the cylindrical body 10.
【００１５】 また図４に示すように、前記金属板１の一側に連結片１１を設けると共に、 該金属板１の他側に前記連結片１１が嵌合可能な嵌合溝１２を形成して、該金属 板１を円筒状に曲成した時、前記連結片１１を前記嵌合溝１２に嵌合させること で、前記円筒体１０が不用意に拡径方向に開かないようにしてもよい。Further, as shown in FIG. 4, a connecting piece 11 is provided on one side of the metal plate 1, and a fitting groove 12 into which the connecting piece 11 can be fitted is formed on the other side of the metal plate 1. When the metal plate 1 is bent into a cylindrical shape, the connecting piece 11 is fitted into the fitting groove 12 so that the cylindrical body 10 is prevented from being opened inadvertently in the radial direction. Good.
