【考案の属する技術分野】[Technical field to which the invention belongs]

本考案折畳み椅子に関し、特に前、後椅子枠の間を肘掛けにより定位させる折 畳み椅子に関する。 The present invention relates to a folding chair, and more particularly to a folding chair in which the front and rear chair frames are positioned by armrests.

【０００２】[0002]

【従来の技術】[Prior art]

図6に示すのは、従来例の折畳み椅子の側視図であり、この種の折畳み椅子１ は互いに交差設置される第1,2の椅子枠11,12を具えて、その互いに交差する部位 を枢軸13により枢接し、枢軸13を軸心として第1、第2の椅子枠11,12が折畳み、展 開ができ、第1、第2の椅子枠11,12の間にシートクッション14を設けて座れるよう にする。従来の折畳み椅子１の第1,2の椅子枠11,12は展開した後、相対定位して 安定に直立状態を保持できるよう、枢軸13の下方に連結桿15を取付けており、連 結桿15の桿体に両端部閉鎖の滑り溝151を開設して、連結桿15両端にそれぞれ枢 着端部152及び活動端部153を形成し、枢着端部152を枢転可能に第1の椅子枠11に 軸枢して、活動端部153を滑り溝151に貫挿する滑動ピン16により第2の椅子枠12 に枢装し、折畳み椅子１を折畳むと、滑動ピン16が滑り溝151沿いに連結桿15の 活動端部153側から枢着端部152側へ移動し、逆に折畳み椅子1を展開させると、 滑動ピン16が滑り溝151沿いに連結桿15の枢着端部152側から活動端部153側へ移 動する。この種の従来例の折畳み椅子１は連結桿15により展開後の第1、第2の椅 子枠11,12を定位させて、安定に地面上に支えさせて座れるが、肘掛けがないため 、腕の置き所がなく、座った際の快適さが大幅に薄れる。 FIG. 6 is a side view of a conventional folding chair. This type of folding chair 1 is provided with first and second chair frames 11 and 12 which are installed crossing each other, and the portions where the chair crosses each other. The first and second chair frames 11, 12 can be folded and unfolded about the pivot 13 as an axis, and a seat cushion 14 is provided between the first and second chair frames 11, 12. Set up and sit down. After the first and second chair frames 11 and 12 of the conventional folding chair 1 are unfolded, a connecting rod 15 is attached below the pivot 13 so that they can be relatively positioned and stably held upright. A sliding groove 151 with both ends closed at the 15 rods is formed, and a pivot end 152 and an active end 153 are formed at both ends of the connecting rod 15, respectively. When the folding chair 1 is folded by pivoting on the chair frame 11 and pivoting the active end 153 into the second chair frame 12 by the sliding pin 16 penetrating the sliding groove 151, the sliding pin 16 When the folding chair 1 is moved from the active end 153 side to the pivot end 152 side of the connecting rod 15 along the 151, and the folding chair 1 is unfolded, the sliding pin 16 is moved along the sliding groove 151 to the pivot end of the connecting rod 15. Move from the 152 side to the active end 153 side. In this type of conventional folding chair 1, the first and second chair frames 11, 12 after being deployed by the connecting rods 15 can be positioned and stably supported on the ground, but since there is no armrest, There is no place for arms, and the comfort when sitting is greatly reduced.

【０００３】 上記従来例の折畳み椅子１における肘掛けがない欠点を改善するため、業界で は折畳み椅子１に肘掛けを取付けたものが開発され、図7が肘掛けを具えた折畳 み椅子２の側視図であり、この折畳み椅子２は、上記従来例の折畳み椅子１とほ ぼ構造は同じであるが、最大に異なるところは、第1、第2の椅子枠21,22に肘掛け 23を組立てて、肘掛け23が前段支承部231及び後段支承部232を具えて、前、後段 支承部231,232をヒンジ部材24により枢接し、折畳み椅子２を折畳む際に、ヒン ジ部材24により前、後段支承部231,232を折合わせることができて、折畳み椅子２ をスムーズに折畳むことができる。しかし乍ら、この折畳み椅子には下記のよう な欠点がある。即ち、１．肘掛け23の前段支承部231と後段支承部232の間のウエ ブ部位に隙間があるので、手腕を容易に傷付けられる。２．折畳み椅子２に連結 桿25と肘掛け23を同時に取付ける必要があるため、構造が比較的複雑となり、生 産コストが高くなる。In order to improve the disadvantage of the conventional folding chair 1 having no armrest, the industry has developed an armrest attached to the folding chair 1, and FIG. 7 shows the side of the folding chair 2 having the armrest. This folding chair 2 has almost the same structure as the folding chair 1 of the above-mentioned conventional example, but the biggest difference is that an armrest 23 is assembled on the first and second chair frames 21 and 22. The armrest 23 has a front support part 231 and a rear support part 232, and the front and rear support parts 231 and 232 are pivotally connected by the hinge member 24. When the folding chair 2 is folded, the front and rear support parts are provided by the hinge member 24. The portions 231 and 232 can be folded, and the folding chair 2 can be folded smoothly. However, this folding chair has the following disadvantages. That is, 1. Since there is a gap in the web portion between the front support portion 231 and the rear support portion 232 of the armrest 23, the hand and arm can be easily damaged. 2. Since it is necessary to attach the connecting rod 25 and the armrest 23 to the folding chair 2 at the same time, the structure becomes relatively complicated and the production cost increases.
