【考案の詳細な説明】
（産業上の利用分野）
本考案は、耐摩耗性に優れ、且つ摩擦音の発生
を防止するようにした椅子における背支柱のロツ
キング装置に関する。[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a locking device for a back support in a chair that has excellent wear resistance and prevents the generation of friction noise.
（従来の技術）
従来における此種のロツキング装置は、第３図
に示す如く軸ａを支持板ｂに通し該支持板の断面
部で受ける方式である。(Prior Art) This type of conventional locking device is of a type in which a shaft a is passed through a support plate b and received at a cross-section of the support plate, as shown in FIG.
このため軸穴、軸の摩耗が早く、且つ摩擦音が
生じるなどの欠点を有する。 For this reason, there are disadvantages such as the shaft hole and shaft wear out quickly and frictional noise is generated.
しかも軸端は露出状態であつて、使用者にとり
衣服や手指をはさむ危険性があり、加えて外観的
にも不体裁である。 Moreover, since the shaft end is exposed, there is a risk that the user's clothes or fingers may get caught, and in addition, the shaft end is unsightly in appearance.
（考案が解決しようとする問題点）
本考案は、簡単な構造にして軸を受部に載置す
るのみで且つ面支承により、前記した欠点を解決
しようとするものである。(Problems to be Solved by the Invention) The present invention attempts to solve the above-mentioned drawbacks by using a simple structure in which the shaft is only placed on a receiving part and by surface bearing.
（問題を解決するための手段）
本考案は、背支柱のロツキング軸を座台兼機構
部で面支持することによつて、所望の目的を達成
することの出来るようにしたものである。(Means for Solving the Problems) The present invention achieves the desired purpose by surface-supporting the locking shaft of the back support with a seat/mechanism section.
（実施例）
以下、本考案の実施例を第１〜２図を参照し乍
ら説明すると、１は座台兼機構部で、その内部に
ロツキング軸受座兼材台補強台２が設けられ、該
台２には円弧状の軸受部３が形成されている。(Embodiment) Hereinafter, an embodiment of the present invention will be described with reference to FIGS. 1 and 2. Reference numeral 1 denotes a seat/mechanism part, in which a rocking bearing seat/material base reinforcing stand 2 is provided; An arcuate bearing portion 3 is formed on the stand 2 .
４は上端に育部５を有する背支柱であつて、そ
の下端附近にロツキング軸６が背支柱の軸方向に
直交して設けられ、且つその下端にはスプリング
受金具７が配設されている。 Reference numeral 4 denotes a back support having a growing portion 5 at its upper end, a locking shaft 6 is provided near its lower end to be perpendicular to the axial direction of the back support, and a spring receiving fitting 7 is provided at its lower end. .
９は脚座１０の主軸で、その上端は前記した座
台兼機構部１の下部に設けた主軸受パイプ８に嵌
合する。 Reference numeral 9 denotes a main shaft of the leg seat 10, the upper end of which fits into the main bearing pipe 8 provided at the lower part of the seat/mechanism section 1 described above.
１１は受金具７に介装されるスプリング部１２
を押え軸１３と共にはさみ込むためのスプリング
押え金具である。 Reference numeral 11 denotes a spring portion 12 interposed in the receiving metal fitting 7.
This is a spring presser fitting for holding the presser shaft 13 together with the presser shaft 13.
（考案の効果）
上記したような本考案によると、背支柱に設け
たロツキング軸は、座台兼機構台の内部に配設の
円弧状に形成された軸受部に単に載置するのであ
るから、組付け操作がきわめて簡便であり、且つ
ロツキング軸は面支承されるので、耐摩耗性に優
れ、しかも摩擦音の発生も防止できるので軽快で
あり、加えてロツキング軸が露出していないため
安全であつて、更に構造も簡単である等、実用上
その効果の大きい考案である。(Effect of the invention) According to the invention as described above, the locking shaft provided on the back support is simply placed on a bearing portion formed in an arc shape inside the seat and mechanism base. The assembly operation is extremely simple, and since the locking shaft is surface-supported, it has excellent wear resistance and prevents the generation of friction noise, making it lightweight.In addition, the locking shaft is not exposed, making it safe. In addition, the structure is simple, and it is a highly effective device in practical terms.
