以下、この発明の実施の形態について説明する。
［発明の実施の形態１］ Embodiments of the present invention will be described below.
Embodiment 1 of the Invention

図１乃至図６には、この発明の実施の形態１を示す。   1 to 6 show a first embodiment of the present invention.

まず構成を説明すると、図１中符号１０は「自動車用開閉体」としての自動車ドアの「係止金具」たるストライカで、このストライカ１０は、連続する金属製の棒部材から一体成形され、略門型（ここでは略コ字状）に折曲げられた鉤部１１と、この門型の鉤部１１の一対の脚部１１ａの基端部から略直角に折曲げられて門型を含む平面を挟んで互いに両側に延長されたベース部１２とを有している。   First, the configuration will be described. Reference numeral 10 in FIG. 1 denotes a striker as a “locking bracket” of an automobile door as an “automobile opening / closing body”. The striker 10 is integrally formed from a continuous metal bar member, A ridge 11 bent into a gate shape (substantially U-shaped here) and a plane including the gate shape that is bent substantially at right angles from the base end portions of the pair of leg portions 11a of the gate-shaped ridge portion 11 And a base portion 12 extending on both sides with respect to each other.

その鉤部１１は、一対の脚部１１ａと、これら脚部１１ａに掛け渡され、車体側の取付け面(図示してない)と平行に伸びる係止杵１１ｂとを有している。   The flange portion 11 includes a pair of leg portions 11a and a locking rod 11b that extends over the leg portions 11a and extends in parallel with a mounting surface (not shown) on the vehicle body side.

また、ベース部１２は、先端部（少なくとも一部）が扁平に形成されて、図示省略の他の部材（車体側の取付け面）に取り付けられる一対の取付部１２ａが形成されている。これら取付部１２ａは、棒材の両端に球形の膨らみ部を作った後に押しつぶして円形に作られており、その中央部にボルト孔１２ｂが穿設されている。   Further, the base portion 12 is formed with a flat tip portion (at least a part), and a pair of attachment portions 12a attached to other members (an attachment surface on the vehicle body side) not shown. These mounting portions 12a are formed into a circular shape by forming a spherical bulge portion at both ends of a bar, and a bolt hole 12b is formed in the center thereof.

このようにストライカ１０は、１本の素材を所要形状に折り曲げて作られているので、製造の過程で機械加工や溶接作業を要しないから製造が容易である。また、成形の過程で切屑その他の無駄な材料を排出しないから、材料の歩留まりがよく廉価に製造できる。   Since the striker 10 is made by bending a single material into a required shape in this way, it is easy to manufacture because it does not require machining or welding operations in the manufacturing process. In addition, since chips and other useless materials are not discharged during the molding process, the yield of the materials can be improved and the production can be made at a low cost.

また、前記取付部１２ａの裏面、すなわち、車体側の取付け面に接する側の面には、無数の山形をした四角錐形の突起１２ｃ…が形成されている。   In addition, innumerable chevron-shaped quadrangular pyramid-shaped protrusions 12c are formed on the back surface of the mounting portion 12a, that is, the surface in contact with the mounting surface on the vehicle body side.

よって、図示してないボルトをボルト孔１２ｂに通し、車体側の取付け面に設けた溶接ナット(図示してない)に螺合させ締め付けるとき、前記取付部１２ａの裏面が車体側の取付け面に対して僅かな傾斜があって傾斜して対面したとしても、ボルトの締め付けに伴って、強く当った部分の四角錐形の突起１２ｃの先端が潰れて低くなる。そのため、取付部１２ａの傾斜を大きく修正せずとも、全面で接触するようになり、締着時の面圧が安定するので、ボルトの緩みがない。
［発明の実施の形態２］ Therefore, when a bolt (not shown) is passed through the bolt hole 12b and screwed into a welding nut (not shown) provided on the mounting surface on the vehicle body, the back surface of the mounting portion 12a is brought to the mounting surface on the vehicle body side. Even if there is a slight inclination with respect to the face, the tip of the quadrangular pyramid-shaped protrusion 12c in the strongly contacted portion is crushed and lowered as the bolt is tightened. For this reason, even if the inclination of the mounting portion 12a is not largely corrected, the entire surface comes into contact, and the surface pressure at the time of fastening is stabilized, so that there is no loosening of the bolt.
[Embodiment 2 of the Invention]

図７乃至図１２には、この発明の実施の形態２を示す。   7 to 12 show a second embodiment of the present invention.

この実施の形態２は、図１中符号１０は自動車ドアの「係止金具」たるストライカで、このストライカ１０は、連続する金属製の棒部材から一体成形され、略門型に折曲げられた鉤部１１と、この門型の鉤部１１の両端部（門型の基端部）から略直角に折曲げられて門型を含む平面を挟んで互いに両側に延長されたベース部１２とを有している。   In the second embodiment, reference numeral 10 in FIG. 1 denotes a striker that is a “locking bracket” of an automobile door. This striker 10 is integrally formed from a continuous metal bar member and bent into a substantially gate shape. A flange portion 11 and base portions 12 that are bent at substantially right angles from both ends (gate-shaped base end portions) of the gate-shaped flange portion 11 and extend to both sides across a plane including the gate shape. Have.

その鉤部１１は、一対の脚部１１ａと、これら脚部１１ａに掛け渡され、車体側の取付け面(図示してない)と平行に伸びる係止杵１１ｂとを有している。   The flange portion 11 includes a pair of leg portions 11a and a locking rod 11b that extends over the leg portions 11a and extends in parallel with a mounting surface (not shown) on the vehicle body side.

また、ベース部１２は、全体が圧縮成形されて扁平に形成されて、図示省略の他の部材（車体側の取付け面）に取り付けられる一対の取付部１２ａが形成されている。これら取付部１２ａは、途中に図１２に示す球形の膨らみ部１３ｂを作った後に押しつぶして円形に作られており、その中央部にボルト孔１２ｂが穿設されている。   In addition, the base portion 12 is entirely formed by compression molding and is formed into a flat shape, and a pair of attachment portions 12a attached to other members (an attachment surface on the vehicle body side) not shown is formed. These attachment portions 12a are formed into a circular shape by forming a spherical bulge portion 13b shown in FIG. 12 in the middle, and a bolt hole 12b is formed in the center thereof.

さらに、このベース部１２には、取付部１２ａからさらに延長された延長部１２ｄが形成され、この延長部１２ｄの先端部に鉤部１１の脚部１１ａの基端部に係止される係止部１２ｅが形成されている。ここでは、係止部１２ｅの先端部に傾斜面１２ｆが形成され、この傾斜面１２ｆが図９に示すように、脚部１１ａの基端部の下側に当接して係止されている。   Further, the base portion 12 is formed with an extension portion 12d further extended from the attachment portion 12a, and is locked to the distal end portion of the extension portion 12d with the base end portion of the leg portion 11a of the flange portion 11. A portion 12e is formed. Here, an inclined surface 12f is formed at the distal end portion of the locking portion 12e, and the inclined surface 12f is in contact with and locked to the lower side of the base end portion of the leg portion 11a as shown in FIG.

次に、かかるストライカ１０の製造方法について図１２を参照して説明する。   Next, the manufacturing method of this striker 10 is demonstrated with reference to FIG.

所定長さの金属製の１本の棒部材１３を略コ字状（略門型形状）に折曲げて鉤部１１を形成する。この略コ字状の両側部の棒状部１３ａの所定位置に他の部分より膨らんだ膨らみ部１３ｂが一対形成され、棒状部１３ａを途中から二点鎖線Ｐに示すように互いに反対方向に略直角に折曲げる。その後、さらに、この折曲げられた端部１３ｃを、矢印Ｑの方向へ平面上で折り返し、その端部１３ｃの傾斜面１３ｄを脚部１１ａの基端部（屈曲部）に当接させてループ状に成形する。 One bar member 13 made of metal having a predetermined length is bent into a substantially U shape (substantially a gate shape) to form the collar portion 11. The substantially U-shaped on both sides of the rod-like portion 13a other inflated than a portion bulged portion 13b at a predetermined position of a pair formed, substantially in opposite directions as the rod-shaped portion 13a in the middle shown in two-dot chain line P Bend it at a right angle. Thereafter, the bent end portion 13c is further folded on a plane in the direction of the arrow Q, and the inclined surface 13d of the end portion 13c is brought into contact with the base end portion (bent portion) of the leg portion 11a to loop. To form.

次いで、その端部１３ｃを上下から挟圧（圧縮）し、膨らみ部１３ｂを含む全体の上面と下面とを平面上に仕上げ、膨らみ部１３ｂを圧縮することで、扁平形状の取付部１２ａを形成する。その後、この取付部１２ａにボルト孔１２ｂを加工してストライカ１０の製造を完了する。   Next, the end portion 13c is clamped (compressed) from above and below, the entire upper surface and lower surface including the bulging portion 13b are finished on a flat surface, and the bulging portion 13b is compressed to form a flat mounting portion 12a. To do. Thereafter, the bolt hole 12b is processed in the mounting portion 12a to complete the manufacture of the striker 10.

なお、そのベース部１２の傾斜面１２ｆと脚部１１ａとは、必要に応じて電気溶接その他の溶着手段によって分離しないように結合することもできる。   It should be noted that the inclined surface 12f of the base portion 12 and the leg portion 11a can be joined so as not to be separated by electric welding or other welding means as required.

また、その扁平な取付部１２ａは、必要に応じてさらに切削、あるいは研削によって仕上げられることもある。   Further, the flat mounting portion 12a may be further finished by cutting or grinding as necessary.

このようなストライカ１０は、ベース部１２の傾斜面１２ｆと脚部１１ａとを当接させてループ状に連続させることにより、ベース部１２の強度を向上させることができる。   Such a striker 10 can improve the strength of the base portion 12 by bringing the inclined surface 12f of the base portion 12 into contact with the leg portion 11a so as to be continuous in a loop shape.

また、ベース部１２の中央部に比較的大きな開口（肉抜き孔）１２ｇが形成されているから、外郭が比較的大きく安定な取付けが可能な形状となっているにも拘らず重量が軽量である。また、製造に際しても一本の線材に塑性加工を加えて外形の大きいベース部１２を形成するものであるから、加工における屑材の排出が少なく、材料の歩留まりがいい等の効果がある。   In addition, since a relatively large opening (thickening hole) 12g is formed in the central portion of the base portion 12, the weight is light despite the fact that the outer shell is relatively large and can be mounted stably. is there. Further, since the base portion 12 having a large outer shape is formed by applying plastic processing to a single wire during manufacture, there is an effect that the waste material is less discharged during processing and the yield of the material is good.

なお、他の構成及び作用は実施の形態１と同様であるので、説明を省略する。
［発明の実施の形態３］ Since other configurations and operations are the same as those of the first embodiment, description thereof is omitted.
