【考案の詳細な説明】
この考案は椅子、特に座椅子やデッキチェアー等の背も
たれ角度を調節可能とするリクライニング装置に関する
。[Detailed Description of the Invention] This invention relates to a reclining device that allows adjustment of the backrest angle of a chair, particularly a seat chair or a deck chair.
この考案の目的とするところは、バンドルによりワンタ
ッチ操作で椅子の背もたれの角度を自由に可変調節でき

する係止爪とを利用した可及的簡単な構造で、コンパク
トに製作でき、正確な作用を期待し得て故障のおそれの
少ない合理的な構成を提供しようとするものである。The purpose of this invention is to create a reclining device that can freely adjust the angle of the backrest of the chair with one-touch operation using a bundle, and to make it as simple as possible by using claw teeth and a locking claw that engages with the reclining device. The objective is to provide a rational structure that can be manufactured compactly, can be expected to function accurately, and has little risk of failure.

爪を係合せしめると共に、回動板を所定位置に回動した
とき係止爪の保合を外す板カムを組合わせた関節金具を
用いたものが多く用いられている。Conventionally, as a backrest angle adjustment device using claws and claw teeth, for example, Japanese Utility Model Publication No. 42-2044 and Japanese Utility Model Publication No. 45-3133 are known.
No. 1, Japanese Patent Publication No. 42-16156, etc., a rotating plate having pawl teeth is pivotally attached to the metal body, a locking pawl is engaged with the pawl tooth, and the rotating plate is held at a predetermined position. Many joint fittings are used in combination with a plate cam that releases the locking pawl when rotated.
ところが、上記のような従来の関節金物は、概して、ワ
ンウェイ方式と呼ばれるもので、背もたれを起立せしめ

用位置にしたのち、該背もたれを後方にいっばいまで倒
してカムを非作用位置に戻し、然るのち背もたれを上方
に所定角度まで起こすという面倒な操作が必要であった
。However, the conventional metal joints described above are generally of the so-called one-way type, in which the angle of the backrest can be changed one step at a time in the direction of raising the backrest, but it is possible to change the angle of the backrest one step at a time in the direction of raising the backrest. To change the angle, first tilt the backrest completely forward to put the cam in the working position, then tilt the backrest all the way back to return the cam to the non-working position, and then move the backrest upward to the specified position. It required a tedious operation to raise it up to an angle.
のみならず、かかる関節金具を用いたものでは、稀に使
用者の操作の誤りや関節金物自体の誤作動等に起因して
、例えば背もたれに体重をかけたとき、該背もたれが急
に後方に倒伏し、使用者が後方の壁で頭を打ちつけるこ
とがあるというような危険があった。In addition, in rare cases where such joint metal fittings are used, the backrest may suddenly move backwards when, for example, one puts weight on the backrest, due to an operational error by the user or a malfunction of the joint metal fitting itself. There was a danger that the user could fall over and hit his or her head on the back wall.
更には、前記のように角度調節時に背もたれを後方にほ
ぼ水平位置になるまで倒す必要があるため、狭いスペー
スでは使用することができない等の不都合があった。Furthermore, as mentioned above, when adjusting the angle, it is necessary to tilt the backrest backward until it reaches a substantially horizontal position, which has the disadvantage that it cannot be used in a narrow space.

点の解決をはかり一層の便宜性の向上をはかったもので
ある。This invention aims to solve the above-mentioned drawbacks by similarly using a pawl tooth and a locking pawl that engages with the pawl, but by configuring the pawl in a compound manner and disengaging the pawl from the pawl by a bundle operation. This is intended to further improve convenience.

阻止され、後者の係止爪4によって同じくその後方への
倒れが阻止されて背枠Bは固定状態に保持される。In the above, as shown in Fig. 5, the upper and lower image body retaining claws 3
, 4 are engaged with the claw teeth 22, 23 at corresponding positions, so that the former locking claw 3 prevents the back frame B from tilting forward, and the latter locking claw 4 prevents the back frame B from tilting backward. The back frame B is prevented from falling down and is held in a fixed state.
この状態から、背枠Bを更に倒したいときは、座部に腰
掛けたまま、バンドル6を引き上げる。From this state, if you want to further recline the back frame B, pull up the bundle 6 while sitting on the seat.
すると回転軸7の回動によって第6図に示すように係合
解除部材5が係止爪4をばね9に抗して下方に押圧し、
爪歯23との係合を解かれる。Then, due to the rotation of the rotating shaft 7, the engagement release member 5 presses the locking pawl 4 downward against the spring 9, as shown in FIG.
The engagement with the pawl teeth 23 is released.
このとき、他方の係止爪3はなお依然として爪歯22と
