〔産業上の利用分野〕
本考案は、椅子の座席の座板と背もたれを、反
発力を持たせて、快適にロツキングさせうるよう
にした椅子に関するものである。[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a chair in which the seat plate and backrest of the seat of the chair have repulsive force and can be comfortably rocked.
着座者が作業を中断して休息するため、椅子の
背もたれ、あるいは座板と背もたれを、ばねによ
る反発力に抗して、後方へロツキングさせるよう
にした椅子は、各種のものが公知である。
Various types of chairs are known in which the backrest of the chair, or the seat plate and the backrest, can be rocked backward against the repulsive force of a spring in order for the seated person to stop working and take a rest.
背もたれのみを後傾させうる椅子は、構成が簡
単で安価に製作しうるが、背もたれを後傾させて
も、着座者の腰部以下の姿勢は作業時と変らない
ため、快適に休息することはできない。また、後
傾させる際、背もたれが着座者の背をこすり上げ
るので、不快である。
A chair in which only the backrest can be tilted back has a simple configuration and can be manufactured at low cost, but even if the backrest is tilted back, the posture of the seated person below the waist remains the same as when working, making it difficult to rest comfortably. Can not. Furthermore, when tilting the seat back, the backrest rubs against the back of the seated person, which is uncomfortable.
座板と背もたれを、左右方向の１本の軸まわり
に回転させて後傾させるようにした従来の椅子で
は、座板を後傾させると、その前部が上昇するの
で、足先が浮き上つて不快である。また、座板と
背もたれのなす角度が、作業時と変らず一定であ
るため、快適な休息姿勢をとることはできない。 In conventional chairs, where the seat and backrest are rotated around a single horizontal axis and tilted back, when the seat is tilted back, the front part of it rises, causing the toes of the feet to rise up. It's uncomfortable. Furthermore, since the angle between the seat plate and the backrest remains the same as when working, it is not possible to take a comfortable resting position.
これを解消するため、座板と背もたれを後傾す
るに従い、両者の角度が次第に増大するようにし
た椅子がある。 To solve this problem, there is a chair in which the angle between the seat and backrest gradually increases as the seat and backrest are tilted backwards.
しかしこの角度は、着座者個人の体格や好み、
あるいはその時の服装等により異なるものである
にも拘らず、上記角度は、椅子の機構上一定であ
るため、常に必ずしも快適であるとは限らない。 However, this angle may vary depending on the physique and preferences of the individual sitting.
Although the angle may vary depending on the person's clothing, etc., the above-mentioned angle is fixed due to the mechanism of the chair, so it is not always comfortable.

ことにより、上述の問題点は解決される。
According to the present invention, the front end of the seat plate is pivotally attached to the front end of the support arm that is provided at the upper end of the leg rod of the chair and faces forward and upward, with a pivot in the left and right direction, and the rear part of the seat plate is equipped with a spring. The left and right front portions of a connecting plate recessed forward are pivoted to the rear portions of the left and right sides of the seat plate with connecting shafts facing in the left and right direction, one end of which is fixed to the seat plate. A spring attached to the other end of the connecting shaft applies an upward elastic rotational force to the seat plate at the front of the connecting plate, and a spring is attached to the upper left and right sides of the connecting plate and to the lower left and right sides of the backrest. is pivoted with a connecting shaft that faces left and right and is fixed to the backrest at one end, and has a spring attached to the other end of the connecting shaft, so that the lower part of the left and right sides of the backrest has forward elasticity with respect to the connecting plate. By applying rotational force, the above-mentioned problems are solved.
座板の前端が、支持アームを介して、その後方
にある脚杆に枢着されているので、座席が後傾し
ても、着座者の足が浮き上がることはない。
Since the front end of the seat plate is pivotally connected to the leg rod located behind it via the support arm, even if the seat is tilted backwards, the occupant's feet will not be lifted up.
座板と背もたれは、連結板を介して、かつ上下
２個所で連結されているので、座席が後傾する
と、背もたれは、連結板とともに、下降向し、か
つ２個所の屈曲部が、それぞれ着座者の体格に順
応して屈曲する。 The seat plate and the backrest are connected via a connecting plate at two places, upper and lower, so when the seat tilts back, the backrest moves downward together with the connecting plate, and the two bent portions each bend when the seat is seated. It bends to adapt to the person's physique.
