The curtain rail 15 has a cross-sectional shape facing the L-shaped members 15a and 15b, and has a slit 15c into which a bolt or the like having a T-shaped head for mounting the device is inserted.

第２の部材２０は、平行して配設される２枚の平板２１，２２がトラス２３で連結された第１の部材と同様の中空形材であって、第１の部材の継手部１４に係合される継手部２４を有する。
継手部２４は、突部２４ａ，２４ｂを有し、第１の部材の継手部１４の突部１４ａ，１４ｂに対してテーパーを利用して嵌合される。
この継手部１４，１５は、例えば、摩擦攪拌接合により接合される。 The second member 20 is a hollow member similar to the first member in which two flat plates 21 and 22 arranged in parallel are connected by a truss 23, and the joint portion 14 of the first member. And a joint portion 24 to be engaged.
The joint part 24 has protrusions 24a and 24b, and is fitted to the protrusions 14a and 14b of the joint part 14 of the first member using a taper.
The joint portions 14 and 15 are joined by, for example, friction stir welding.

第２の部材２０にも、機器を取付けるためのカーテンレール２５が一体に設けられる。
カーテンレール２５は、Ｌ字形状の部材２５ａ，２５ｂが対向する断面形状を有し、機器を取付けるためのＴ字形の頭部を有するボルト等が挿入されるスリット２５ｃを有する。 The second member 20 is also integrally provided with a curtain rail 25 for mounting equipment.

構体を構成する中空形材１０，１２は幅方向に、例えば、プラス・マイナス１．５ｍｍの寸法公差を有する。
また、継手部１４，２４の溶接後の収縮は、幅方向に０．５〜１．０ｍｍ発生する。 The hollow shape members 10 and 12 constituting the structure have a dimensional tolerance of, for example, plus or minus 1.5 mm in the width direction.
Moreover, the shrinkage | contraction after welding of the joint parts 14 and 24 generate | occur | produces 0.5-1.0 mm in the width direction.

並行するカーテンレール１５と２５を利用して機器等を支持する場合に、２個のカーテンレール１５，２５のスリット１５ｃ，２５ｃの中心線間の距離Ｄは、設計寸法に対して、１〜３ｍｍの誤差が発生する。
この誤差を吸収するために、機器の取付作業において、寸法を合わせる余分な工数を必要とする。 In the case of supporting equipment using the parallel curtain rails 15 and 25, the distance D between the center lines of the slits 15c and 25c of the two curtain rails 15 and 25 is 1 to 3 mm with respect to the design dimension. Error occurs.
In order to absorb this error, an extra man-hour for matching the dimensions is required in the installation work of the equipment.

また、図５に示すように車体構体１は、全長寸法Ｌとして、例えば２０ｍｍ程度の寸法を有する。カーテンレール１５，２５は、この構体１の全長にわたって使用されるとは限らず、用途に応じて不用部分のカーテンレール１５´，２５´は、機械加工等により除去する必要がある。
そこで本発明の目的は、上述した不具合を解消するカーテンレールの取付方法及びカーテンレール部材を提供するものである。 As shown in FIG. 5, the vehicle body structure 1 has a length L of, for example, about 20 mm. The curtain rails 15 and 25 are not necessarily used over the entire length of the structure 1, and the unnecessary curtain rails 15 'and 25' need to be removed by machining or the like depending on the application.
Accordingly, an object of the present invention is to provide a curtain rail mounting method and a curtain rail member that eliminate the above-mentioned problems.

上記目的を達成するために、本発明のカーテンレールを製作する方法は、閉断面を構成するカーテンレール成形部を有する部材を用意し、部材を接合した後にカーテンレール成形部に機械加工によりカーテンレール用のスリットを形成するものである。
また、カーテンレール成形部の不必要な部分を機械加工により除去することもできる。 In order to achieve the above object, a method for manufacturing a curtain rail according to the present invention is to prepare a member having a curtain rail molding part constituting a closed cross section, and after joining the members, the curtain rail molding part is machined by machining. Forming a slit.
Further, unnecessary portions of the curtain rail molding portion can be removed by machining.

本発明によれば、車両構体のカーテンレールを簡単に、かつ、精度良く構成することができる。   ADVANTAGE OF THE INVENTION According to this invention, the curtain rail of a vehicle structure can be comprised easily and accurately.

図１乃至図３は、本発明の実施例を示す説明図である。
車両構体１は、中空形材である部材１１０，１２０を長手方向に並べ、継手部１１４，１２４を摩擦攪拌接合して構成される。第１の部材１１０は、平板１１１，１１２をトラス１１３で連結した構造を有し、第２の部材１２０は、平板１２１，１２２をトラス１２３で連結した構成を有する。 1 to 3 are explanatory views showing an embodiment of the present invention.
The vehicle structure 1 is configured by arranging members 110 and 120, which are hollow shapes, in the longitudinal direction, and friction joints 114 and 124. The first member 110 has a structure in which flat plates 111 and 112 are connected by a truss 113, and the second member 120 has a configuration in which flat plates 121 and 122 are connected by a truss 123.

第１の部材１１０の平板１１１とトラス１１３の頂部１１４の上部には、カーテンレール成形部１１５が設けられる。このカーテンレール成形部１１５は、閉断面を構成し、中空形材である第１の部材１１０の押出し加工時に同時に成形される。   On the upper part of the flat plate 111 of the first member 110 and the top part 114 of the truss 113, a curtain rail forming part 115 is provided. The curtain rail forming portion 115 has a closed cross section and is formed simultaneously with the extrusion of the first member 110 that is a hollow material.

第２の部材１２０の平板１２１とトラス１２３の頂部１２４の上部には、カーテンレール成形部１２５が設けられる。このカーテンレール成形部１２５は、閉断面を構成し、中空形材１２０の押出し加工時に同時に成形される。   On the upper part of the flat plate 121 of the second member 120 and the top portion 124 of the truss 123, a curtain rail forming portion 125 is provided. The curtain rail forming portion 125 has a closed cross section and is simultaneously formed when the hollow shape member 120 is extruded.

図２は、第１の部材１１０のカーテンレール成形部１１５と、第２の部材１２０のカーテンレール成形部１２５に対して機械加工によりカーテンレール用のスリットを加工する工程を示す。
この加工は、例えば、接合された車両構体１を加工機械のテーブル上に載置し、ミーリング工具等の加工工具２００を用いて実行される。 FIG. 2 shows a process of machining the curtain rail slits by machining the curtain rail molding part 115 of the first member 110 and the curtain rail molding part 125 of the second member 120.
This processing is performed using, for example, a processing tool 200 such as a milling tool by placing the joined vehicle structure 1 on a table of a processing machine.

加工工具２００は、カーテンレールのスリットの幅寸法に対応した外径寸法を有し、紙面に垂直な方向に加工ヘッドを移動させて所定の加工を行う。
機械加工により溝の切削を行うので、第１の部材１１０のカーテンレールの溝の中心部と、第２の部材１２０のカーテンレールのスリットの中心部の間の寸法Ｄ１は、高い精度で加工することができ、要求される精度を容易に満足することができる。カーテンレール成形部１１５をトラスの頂部１１４、１２４上に設けることにより、機械加工時の押圧力にも容易に耐えることができる。 The processing tool 200 has an outer diameter corresponding to the width of the slit of the curtain rail, and performs a predetermined processing by moving the processing head in a direction perpendicular to the paper surface.
Since the cutting grooves by machining, the center portion of the groove of the curtain rail of the first member 110, the dimension D 1 of the between the center of the slit of the curtain rail of the second member 120 is machined with high precision And the required accuracy can be easily satisfied. By providing the curtain rail forming portion 115 on the top portions 114 and 124 of the truss, it is possible to easily withstand the pressing force during machining.

図３は、上述した工程により製作されてカーテンレール１１５，１２５の構造の詳細を示す。
カーテンレール１１５は、対向するＬ字形の部材１１５ａ，１１５ｂと、切削加工されたスリット１１５ｃで形成される。 FIG. 3 shows the details of the structure of the curtain rails 115 and 125 manufactured by the process described above.
The curtain rail 115 is formed by facing L-shaped members 115a and 115b and a slit 115c that has been cut.

同様に、カーテンレール１２５は、対向するＬ字形の部材１２５ａ，１２５ｂと、切削加工されたスリット１２５ｃで形成される。
カーテンレール１１５，１２５のスリット１１５ｃ，１２５ｃの間隔寸法Ｄ１は、機械加工により高精度に加工することができる。 Similarly, the curtain rail 125 is formed by opposing L-shaped members 125a and 125b and a slit 125c that has been cut.
Slit 115c, spacing dimension D 1 of the 125c of the curtain rail 115, 125 can be processed with high accuracy by machining.

また、２本のスリット１１５ｃ，１２５ｃの平行度も高精度に加工されるので、カーテンレールを利用した機器の取付け、取外し作業等を効率よく行うことができる。
このカーテンレール成形部１１５，１２５は、部材１１０，１２０の全長にわたって成形されている。 In addition, since the parallelism of the two slits 115c and 125c is processed with high accuracy, it is possible to efficiently perform installation and removal operations of equipment using curtain rails.
The curtain rail forming portions 115 and 125 are formed over the entire length of the members 110 and 120.

そこで、スリットの加工時に、使用しない部分のカーテンレール成形部を切削除去することにより、余肉を除去し、車両構体１の軽量化を図ることができる。   Therefore, when the slit is machined, the unused part of the curtain rail molding part is cut and removed, so that the surplus material can be removed and the weight of the vehicle structure 1 can be reduced.
