図１に、実施形態１に係る本発明金具１を示す。この本発明金具１は、底壁２と、一対の側壁３と、主爪部４と、を具備する。 <Embodiment 1>
-Invention bracket 1-
FIG. 1 shows a metal fitting 1 of the present invention according to the first embodiment. The metal fitting 1 of the present invention includes a bottom wall 2, a pair of side walls 3, and a main claw portion 4.

前記底壁２は、円弧半径４．５ｍｍの半円形の断面形状を有する。又、長手方向（軸方向に沿う方向）の長さ（Ｌ）は、４０ｍｍとなされている。   The bottom wall 2 has a semicircular cross-sectional shape with an arc radius of 4.5 mm. The length (L) in the longitudinal direction (direction along the axial direction) is 40 mm.

前記側壁３は、前記底壁２の両端縁に沿って、基端となる一辺（以下、「基端辺」と称する。）３１が配された一対の平板状の部材（幅：Ｔ＝５．４ｍｍ）である。対向する一対の前記側壁３は、基端辺３１同士の間隔（Ｒ０）に対し、遊端辺３２同士の間隔（Ｒ１）が小さくなるように（Ｒ０→Ｒ１：９ｍｍ→８．１ｍｍ）傾斜している。なお、前記側壁３の一方の角部には、表裏を貫通する貫通孔６が設けられている。 The side wall 3 is a pair of flat members (width: T = 5) in which one side (hereinafter referred to as “base end side”) 31 serving as a base end is disposed along both end edges of the bottom wall 2. 4 mm). The pair of opposing side walls 3 are configured such that the interval (R 1 ) between the free end sides 32 is smaller than the interval (R 0 ) between the base end sides 31 (R 0 → R 1 : 9 mm → 8. 1 mm) is inclined. In addition, a through hole 6 penetrating the front and back is provided at one corner of the side wall 3.

本実施形態において、前記底壁２と一対の前記側壁３とは、一枚のステンレス製の金属板（ＳＵＳ３０４ 厚さ０．５ｍｍ）を屈曲して一体的に形成されたものであり、前記底壁２と、一対の前記側壁３と、によって囲まれた空間が保持空間Ｓとなる。   In the present embodiment, the bottom wall 2 and the pair of side walls 3 are integrally formed by bending a stainless steel metal plate (SUS304 thickness 0.5 mm), and the bottom A space surrounded by the wall 2 and the pair of side walls 3 is a holding space S.

前記主爪部４は、前記側壁３の一方の長手方向に沿って、都合三カ所に設けられている。前記主爪部４は、前記側壁３の一部を、略Ｕ字状に切り欠いて、先端部４１側を前記保持空間Ｓ側に向かって折り起こすことによって、前記保持空間Ｓに向かって突出させている。各主爪部４は、いずれも先端部４１が前記側壁３の長手方向に沿う一方向側となるようにして形成されている。なお、前記側壁３の一部を切り欠いて前記主爪部４を形成する際に残された部分、言い換えれば、前記主爪部４における前記側壁３と繋がっている部分が、特許請求の範囲における「基端部（４２）」に相当する部分である。   The main claw portion 4 is provided at three convenient locations along one longitudinal direction of the side wall 3. The main claw portion 4 protrudes toward the holding space S by cutting out a part of the side wall 3 in a substantially U shape and folding the tip portion 41 side toward the holding space S side. I am letting. Each main claw portion 4 is formed such that the tip portion 41 is on one side along the longitudinal direction of the side wall 3. In addition, the part left when notching a part of the said side wall 3 and forming the said main nail | claw part 4, ie, the part connected with the said side wall 3 in the said main nail | claw part 4, is a claim. This is a portion corresponding to the “base end portion (42)”.

図２（ａ）、（ｂ）に示すように、この本発明金具１は、前記保持空間Ｓの開口部側をアプローチ側として、ボルト１００の軸部１０１にあてがい、前記底壁２を押圧することによって、前記ボルト１００の軸部１０１に対して抱き付くようにして取り付けられる。本発明金具１は、一対の前記側壁３の内面間の間隔より少し大きい直径（好ましくは、前記基端辺３１同士の間隔（Ｒ０）より０．１〜３ｍｍ大きい直径）を有するボルト１００に取り付けられることを前提としており、従って、前記保持空間Ｓ内に嵌め入れられた前記ボルト１００の軸部１０１は、対向する前記側壁３にて弾性的に挟持される。 As shown in FIGS. 2A and 2B, the metal fitting 1 of the present invention is applied to the shaft portion 101 of the bolt 100 with the opening side of the holding space S as the approach side and presses the bottom wall 2. Thus, the bolt 100 is attached to the shaft portion 101 so as to be hugged. The metal fitting 1 of the present invention is a bolt 100 having a diameter slightly larger than the distance between the inner surfaces of the pair of side walls 3 (preferably, a diameter 0.1 to 3 mm larger than the distance (R 0 ) between the base end sides 31). Therefore, the shaft portion 101 of the bolt 100 fitted in the holding space S is elastically sandwiched between the opposing side walls 3.

本発明金具１を前記ボルト１００の軸部１０１に向かって押し込むと、前記保持空間Ｓ内に向かって突出する前記主爪部４は、前記ボルト１００の軸部１０１に存するネジ山１０２によって弾性的に後退させられるが、その先端部４１は、ネジ山１０２の谷間に侵入する（図２（ｃ）参照）。   When the metal fitting 1 of the present invention is pushed toward the shaft portion 101 of the bolt 100, the main claw portion 4 protruding into the holding space S is elasticized by the thread 102 existing on the shaft portion 101 of the bolt 100. However, the tip 41 enters the valley of the thread 102 (see FIG. 2C).

そして、この状態で、本発明金具１に対して、前記ボルト１００の軸部１０１の一端（図中下方）に向かう負荷が与えられると、前記主爪部４の先端部４１が、前記ボルト１００の軸部１０１に設けられたネジ山１０２に突き当たり、もって、本発明金具１の前記軸部１０１の一端に向かっての摺動が好適に規制される。   In this state, when a load directed to one end (downward in the drawing) of the shaft portion 101 of the bolt 100 is applied to the metal fitting 1 of the present invention, the tip portion 41 of the main claw portion 4 is moved to the bolt 100. The end face of the shaft portion 101 of the present invention 1 is suitably restricted by striking the thread 102 provided on the shaft portion 101 of the present invention.

ところで、本実施形態においては、前記主爪部４につき、前記側壁３の一方にのみ設けているが、例えば、図３（ａ）に示すように、前記主爪部４は、前記側壁３の両方に対して設けたり、図３（ｂ）に示すように、前記底壁２に対して設けたりしても良い。なお、本実施形態においては、前記主爪部４を形成するにあたり、前記側壁３の一部を略Ｕ字状に切り欠いているが、「略Ｕ字状に切り欠く」とは、基端部４２を残した状態で前記側壁３の一部を切り欠き、もって、前記主爪部４の先端部４１側となる部分を形成することを意味し、厳密なＵ字の文字形状に限定されるものではない。   By the way, in the present embodiment, the main claw portion 4 is provided only on one side of the side wall 3. For example, as shown in FIG. It may be provided for both, or may be provided for the bottom wall 2 as shown in FIG. In the present embodiment, when the main claw portion 4 is formed, a part of the side wall 3 is notched in a substantially U shape, but “notched in a substantially U shape” This means that a part of the side wall 3 is cut out with the portion 42 left, thereby forming a portion that becomes the tip 41 side of the main claw portion 4, and is limited to a strict U-shaped character shape. It is not something.

又、本実施形態においては、前記底壁２につき、半円形の断面形状を有するものとしているが、前記底壁２の形状は特に限定されるものではなく、例えば、図３（ｃ）に示すような平板状としても良い。   In the present embodiment, the bottom wall 2 has a semicircular cross-sectional shape, but the shape of the bottom wall 2 is not particularly limited. For example, as shown in FIG. It is good also as such flat form.

更に、本実施形態においては、前記側壁３につき、平板状としているが、前記側壁３の形状は特に限定されるものではなく、例えば、図３（ｄ）に示すように、ボルト１００の軸部１０１に沿う湾曲部を有する形状としても良い。   Further, in the present embodiment, the side wall 3 has a flat plate shape, but the shape of the side wall 3 is not particularly limited. For example, as shown in FIG. It is good also as a shape which has a curved part along 101. FIG.

なお、本実施形態においては、厚さ０．５ｍｍの金属板を屈曲して前記底壁２と前記側壁３とを一体的に形成しているが、前記底壁２と前記側壁３とをそれぞれ別体として形成し、溶接等の手段により結合しても良い。   In the present embodiment, the bottom wall 2 and the side wall 3 are integrally formed by bending a metal plate having a thickness of 0.5 mm, but the bottom wall 2 and the side wall 3 are respectively formed. It may be formed as a separate body and joined by means such as welding.

又、本実施形態においては、厚さ０．５ｍｍの金属板を用いて本発明金具１を製造しているため、前記主爪部４の厚さも０．５ｍｍとなるが、前記主爪部４の厚さは、０．２５〜１．５０ｍｍの範囲内（より好ましくは、０．３５〜１．０ｍｍ、更に好ましくは０．４〜０．７５ｍｍの範囲内）とすることが好ましい。従って、本実施形態のように一枚の金属板を屈曲して本発明金具１を製造する場合には、金属板として、厚さ０．２５〜１．５０ｍｍの範囲内（より好ましくは、０．３５〜１．０ｍｍ、更に好ましくは０．４〜０．７５ｍｍの範囲内）のものを用いることが好ましい。   In the present embodiment, since the metal fitting 1 of the present invention is manufactured using a metal plate having a thickness of 0.5 mm, the thickness of the main claw portion 4 is also 0.5 mm. Is preferably in the range of 0.25 to 1.50 mm (more preferably in the range of 0.35 to 1.0 mm, still more preferably in the range of 0.4 to 0.75 mm).

なお、本実施形態においては、前記側壁３の各遊端辺３２側において、内面間の間隔を広げるガイド部３３が設けられている。このガイド部３３は、前記側壁３の遊端辺３２から一定の代幅を空けた位置を屈曲ライン３３０とし、この屈曲ライン３３０に沿って前記側壁３を屈曲することによって形成されたものである。   In the present embodiment, a guide portion 33 is provided on the side of each free end side 32 of the side wall 3 so as to widen the interval between the inner surfaces. The guide portion 33 is formed by bending the side wall 3 along the bending line 330 at a position spaced apart from the free end 32 of the side wall 3 by a certain margin. .

又、本実施形態に係る本発明金具１においては、索体取り付け部となる貫通孔６を、前記側壁３（前記ガイド部３３）各々の中央部に設けた耳部６０に配している。即ち、この貫通孔６に対し前記索体１１を取り付ければ、本発明装置１０となる。   Moreover, in this invention metal fitting 1 which concerns on this embodiment, the through-hole 6 used as a cable body attaching part is distribute | arranged to the ear | edge part 60 provided in the center part of each said side wall 3 (the said guide part 33). That is, when the cable body 11 is attached to the through hole 6, the device 10 of the present invention is obtained.

本実施形態において、前記主爪部４は、各側壁３の長手方向に沿って、二カ所ずつ、合計４カ所に設けられている。前記主爪部４は、前記側壁３の一部を、略Ｕ字状に切り欠いて、先端部４１側を保持空間Ｓ側に向かって折り起こすことによって、前記保持空間Ｓに向かって突出させている。各主爪部４は、いずれも先端部４１が前記側壁３の長手方向に沿う一方向側となるようにして形成されている。   In the present embodiment, the main claw portion 4 is provided at a total of four locations, two locations along the longitudinal direction of each side wall 3. The main claw portion 4 is protruded toward the holding space S by cutting out a part of the side wall 3 in a substantially U shape and folding the front end portion 41 side toward the holding space S side. ing. Each main claw portion 4 is formed such that the tip portion 41 is on one side along the longitudinal direction of the side wall 3.

一方、前記副爪部５は、前記主爪部４に対し、前記側壁３の中央部を挟んで互いに対象となる位置に設けられている。前記副爪部５も、前記側壁３の一部を、基端部５２となる部分を残した状態で切り欠いて、先端部５１側を前記保持空間Ｓ側に向かって折り起こすことによって形成されてなるものであるが、前記副爪部５は、その先端部５１が前記主爪部４の先端部４１に対して逆方向、即ち、前記側壁３の長手方向に沿う他方向側となるようにして形成されている。   On the other hand, the sub claw portion 5 is provided at a target position with respect to the main claw portion 4 across the central portion of the side wall 3. The sub claw portion 5 is also formed by cutting out a part of the side wall 3 with the portion that becomes the base end portion 52 left, and folding the tip end portion 51 side toward the holding space S side. However, the auxiliary claw portion 5 has its tip 51 located in the opposite direction to the tip 41 of the main claw 4, that is, in the other direction along the longitudinal direction of the side wall 3. Is formed.

更に、本実施形態に係る本発明金具１は、脱落防止用爪部７を具備する。この脱落防止用爪部７は、各側壁３の長手方向に沿って設けられている。前記脱落防止用爪部７も、前記側壁３の一部を略Ｕ字状に切り欠いて形成されたものである。前記脱落防止用爪部７は、その基端部が、前記側壁３に前記ガイド部３３を形成した際の屈曲ライン３３０上となされているため、前記屈曲ライン３３０に沿って前記側壁３を屈曲した際に、その先端部が立ち上がり、もって、先端部が保持空間Ｓに向かって突出する。   Furthermore, the metal fitting 1 according to the present embodiment includes a claw portion 7 for preventing dropout. The drop-off preventing claw portion 7 is provided along the longitudinal direction of each side wall 3. The drop prevention claw portion 7 is also formed by cutting out a part of the side wall 3 in a substantially U shape. Since the base end of the drop-off preventing claw portion 7 is on the bending line 330 when the guide portion 33 is formed on the side wall 3, the side wall 3 is bent along the bending line 330. When this occurs, the tip portion rises, and the tip portion projects toward the holding space S.

図８に示すように、このような構成を有する本発明金具１は、前記ガイド部３３をアプローチ側として、ボルト１００の軸部１０１にあてがい、前記底壁２を押圧することによって、ボルト１００の軸部１０１に取り付けられる。前記側壁３の内面間の距離を広げる前記ガイド部３３によって、この取り付け作業はより一層簡便となる。   As shown in FIG. 8, the metal fitting 1 having such a configuration is applied to the shaft portion 101 of the bolt 100 with the guide portion 33 as the approach side, and the bottom wall 2 is pressed, whereby the bolt 100 is It is attached to the shaft part 101. This mounting operation is further simplified by the guide portion 33 that increases the distance between the inner surfaces of the side walls 3.

本発明金具１をボルト１００の軸部１０１に向かって押圧すると、前記保持空間Ｓ内に向かって突出する前記主爪部４は、軸部１０１に存するネジ山１０２によって弾性的に後退させられるが、前記ボルト１００が前記保持空間Ｓ内に収まると、その先端部４１は、ネジ山１０２の谷間に侵入する。   When the metal fitting 1 of the present invention is pressed toward the shaft portion 101 of the bolt 100, the main claw portion 4 protruding into the holding space S is elastically retracted by the screw thread 102 existing in the shaft portion 101. When the bolt 100 is accommodated in the holding space S, the tip 41 enters the valley of the screw thread 102.

一方、前記副爪部５も、押圧の際に、軸部１０１に存するネジ山１０２によって弾性的に後退させられるが、前記ボルト１００が前記保持空間Ｓ内に収まると、その先端部５１は、ネジ山１０２の谷間に侵入する。   On the other hand, the auxiliary claw portion 5 is also elastically retracted by the screw thread 102 existing in the shaft portion 101 when pressed, but when the bolt 100 is accommodated in the holding space S, the tip portion 51 is It penetrates into the valley of the thread 102.

又、本発明金具１をボルト１００の軸部１０１に向かって押圧すると、前記保持空間Ｓ内に向かって突出する前記脱落防止用爪部７は、軸部１０１に存するネジ山１０２によって弾性的に後退させられるが、前記ボルト１００が前記保持空間Ｓ内に収まると、前記脱落防止用爪部７が再度立ち上がる。即ち、この状態下、前記脱落防止用爪部７は、ボルト１００から本発明金具１が脱落する方向への移動を規制する役割を担う。   Further, when the metal fitting 1 of the present invention is pressed toward the shaft portion 101 of the bolt 100, the drop-off preventing claw portion 7 protruding into the holding space S is elastically formed by the screw thread 102 existing in the shaft portion 101. Although being retracted, when the bolt 100 is accommodated in the holding space S, the drop-off preventing claw portion 7 rises again. That is, in this state, the drop-off preventing claw portion 7 plays a role of restricting the movement of the metal fitting 1 from the bolt 100 in the direction of dropping.

そして、この状態で、ボルト１００の軸部１０１の一端（図中下方）に向かう負荷が与えられると、前記主爪部４の先端部４１が、ボルト１００の軸部１０１に設けられたネジ山１０２に突き当たり、もって、本発明金具１の前記軸部１０１の一端に向かっての摺動が好適に規制される。   In this state, when a load is applied toward one end (downward in the drawing) of the shaft portion 101 of the bolt 100, the tip 41 of the main claw portion 4 is threaded on the shaft portion 101 of the bolt 100. With this, the sliding toward the one end of the shaft portion 101 of the metal fitting 1 of the present invention is suitably restricted.

一方、この状態で、ボルト１００の軸部１０１の他端（図中上方）に向かう負荷が与えられると、前記副爪部５の先端部５１が、ボルト１００の軸部１０１に設けられたネジ山１０２に突き当たり、もって、本発明金具１の前記軸部１０１の他端に向かっての摺動が好適に規制される。   On the other hand, in this state, when a load is applied toward the other end (upward in the drawing) of the shaft portion 101 of the bolt 100, the tip 51 of the sub claw portion 5 is screwed on the shaft portion 101 of the bolt 100. Abutting on the mountain 102, the sliding of the metal fitting 1 of the present invention 1 toward the other end of the shaft portion 101 is suitably restricted.

即ち、本実施形態に係る本発明金具１は、前記主爪部４と前記副爪部５の共働によって、ボルト１００の軸部１０１の一端及び他端に向かって摺動することをいずれも規制するものであり、従って、ボルト１００に取り付ける際に、取り付け方向を考慮する必要が無くなる。これより、取り付け作業がより一層簡便となる。   In other words, the metal fitting 1 according to the present embodiment slides toward one end and the other end of the shaft portion 101 of the bolt 100 by the cooperation of the main claw portion 4 and the sub claw portion 5. Therefore, when attaching to the bolt 100, it is not necessary to consider the attaching direction. As a result, the attaching operation is further simplified.

その余は、前記実施形態１において説明した事項と同様であり、繰り返しを避けるべくここでは、説明を省略する。   The rest is the same as that described in the first embodiment, and the description is omitted here to avoid repetition.
