Description

本考案は一種の背もたれ枠、座枠の傾斜角度が調整できる椅子を斜めに横たえる機構に関する。   The present invention relates to a kind of backrest frame and a mechanism for laying a chair that can adjust the inclination angle of a seat frame obliquely.

従来の椅子では、座り心地の快適さを向上するため、背もたれを後へ倒して斜めに横たえられるような設計を施している。図10に示したのは従来の一構造であり、主に脚枠1'、背もたれ2'、座3'、足掛け4'からなる。該脚枠1'の後方に枢接孔11'を設け、前方に固定ボタン12'を設け、背もたれ2'の下方に枢接孔21'を設けて枢接棒5'によって枢接孔11'、21'を貫通してから脚枠1'と枢接する。背もたれ2'の底部は座3'の後端と枢接して底端には連接棒22'の一端を枢接して組合せる。座3'の中央の下方にスライドバー31'を設け、該スライドバー31'は固定ボタン12'に応じて移動でき、固定ボタン12'によってしっかり固着でき、足掛け4'は連接棒22'のもう一端と枢接している。   Conventional chairs are designed to lie diagonally with the backrest tilted backwards to improve comfort. FIG. 10 shows a conventional structure, which mainly comprises a leg frame 1 ′, a backrest 2 ′, a seat 3 ′, and a legrest 4 ′. A pivot hole 11 'is provided at the rear of the leg frame 1', a fixed button 12 'is provided at the front, a pivot hole 21' is provided below the backrest 2 ', and a pivot hole 11' is provided by the pivot rod 5 '. , 21 'and then pivot with the leg frame 1'. The bottom portion of the backrest 2 'is pivotally connected to the rear end of the seat 3', and one end of the connecting rod 22 'is pivotally combined with the bottom end. A slide bar 31 'is provided below the center of the seat 3'. The slide bar 31 'can be moved in accordance with the fixed button 12' and can be firmly fixed by the fixed button 12 ', and the footrest 4' is connected to the connecting rod 22 '. It is pivoted with one end.

図11を参照する。前記した構造では固定ボタン12'を弛めると利用者の横たわる力によって背もたれ2'を後へ倒すことができる。背もたれ2'を後へ倒すとき、枢接棒5'を回転軸にして回転させると同時に座3'を連動して前後へ移動させることができ、同時に連接棒22'の前への移動に連動して足掛け4'が展開するため、背もたれ2'と座3'との間の角度aが増大し、固定ボタン12'を締めることによって後へ倒す角度を固定できる。   Please refer to FIG. In the structure described above, when the fixing button 12 'is loosened, the backrest 2' can be tilted backward by the user's lying force. When the backrest 2 'is tilted back, the seat 3' can be moved back and forth while simultaneously rotating with the pivot rod 5 'as the rotation axis, and at the same time linked to the forward movement of the connecting rod 22'. Then, since the legrest 4 ′ is deployed, the angle a between the backrest 2 ′ and the seat 3 ′ increases, and the angle to be tilted backward can be fixed by tightening the fixing button 12 ′.

しかし前記した構造は次のような欠点を持っている。背もたれ2'を後へ倒すとき、座3'も同時に上昇するため、座3'と床の平行線cとの夾角bは著しく増大したままで、横たわる人の臀部が背もたれ2'と座3'との間に落ち難くなるので座り心地が悪い。   However, the structure described above has the following drawbacks. When the backrest 2 ′ is tilted backward, the seat 3 ′ also rises at the same time, so that the depression angle b between the seat 3 ′ and the parallel line c of the floor remains significantly increased, and the buttocks of the person lying on the backrest 2 ′ and the seat 3 ′ It ’s hard to fall between, so it ’s not comfortable.

固定ボタン12'を弛めて背もたれ2'を後へ倒すとき、緩衝設計がないため、背もたれ2'を瞬間的に大幅に後へ倒してしまうため角度を調整し難く、座り心地が悪いなどの欠点をもたらす。
後へ倒した背もたれ2'を倒す前の状態に戻す場合、人の体重で座3'を下げるか或いは人が椅子から離れて調整しなければならないため、復帰調整が不便になるという欠点を有する。
When the fixed button 12 'is loosened and the backrest 2' is tilted backwards, there is no cushioning design, so the backrest 2 'is momentarily tilted backwards, making it difficult to adjust the angle and poor sitting comfort. Brings a drawback.
When returning to the state before the backrest 2 'that was tilted back is brought down, the seat 3' must be lowered by the weight of the person or the person must adjust away from the chair, so that the return adjustment is inconvenient. .
