Description
本發明係有關於一種座椅椅背角度調整結構，尤指一種僅需樞轉椅背即可調整椅背角度的角度調整結構。 The present invention relates to a seat back angle adjustment structure, in particular to an angle adjustment structure that can adjust the chair back angle only by pivoting the chair back.
按，椅子是每天都要使用的家具，尤其是為了長時間坐著舒服，調整椅背角度是相當重要的，習知的辦公椅僅能調整整個椅背的角度，而辦公時不可能後仰貼平整個椅背，所以座椅椅背角度調整結構是相當必要的。 Press, a chair is a piece of furniture that is used every day. Especially in order to sit comfortably for a long time, it is very important to adjust the angle of the chair back. The conventional office chair can only adjust the angle of the entire chair back, and it is impossible to tilt it back when working. Flatten the entire chair back, so the seat back angle adjustment structure is quite necessary.
然而，習知的座椅椅背角度調整結構由於仍需撥動拉桿並拉推椅背以進行調整與固定角度，實為不便，若能僅用樞轉椅背的方式即可調整與固定角度，於使用上必大有裨益。 However, the conventional seat back angle adjustment structure is inconvenient because it still requires pulling the lever and pulling and pushing the chair back to adjust and fix the angle.

When in the initial state, due to the elastic force of the elastic member, Push the rotating member and then push the adjusting member, so that the clamping piece can be stuck in the rack portion, thereby fixing the angle of the chair back frame, and pivoting the chair back frame to adjust the angle so that the The chair back frame affects the adjusting member, and the clamping piece can move on the rack portion to adjust and fix the angle of the chair back frame. When the chair back frame continues to pivot, the clamping piece When the piece is no longer stuck in the rack part, the clamping piece abuts the flat part. Since the horizontal surface of the flat part is higher than the rack part, the adjusting member presses down the rotating member to allow the locking piece to When the solid block is aligned with the clamping hole, and the chair back frame is further pivoted, the back push portion will push the clamping block, thereby rotating the rotating member and the clamping block will be stuck in the clamping hole. The clamping block resists the elastic force of the elastic member to limit the height of the rotating member so that the rotating member no longer pushes against the adjusting member. At this time, the user can push the back frame in the opposite direction to pivot the chair back frame to adjust the angle. Return to the original position. At this time, the forward pushing part enters the clamping hole and pushes the clamping block away from the clamping hole. The elastic member again pushes the rotating member with elastic force and then pushes the adjusting member. The locking piece continues to be stuck in the rack portion and returns to the initial state.

本發明實際使用之態勢，由第四圖與第五圖所示觀之，拉動所述椅背框(10)即可以該底環(12)為軸心令所述椅背框(10)相對於該椅背架(20)樞轉椅調整角度，再請依序由第六圖到第十一圖所示觀之，處於初始狀態時，由於所述彈性件(322)以彈力頂推該旋轉件(32)進而頂推所述調整件(33)，讓所述卡固片(31)可卡於該齒條部(332)內，從而固定所述椅背框(10)的角度，樞轉所述椅背框(10)以調整角度，令該椅背框體(11)牽動所述調整件(33)，所述卡固片(31)可於該齒條部(332)上移動以調整並固定所述椅背框(10)的角度，當持續樞轉所述椅背框(10)而令所述卡固片(31)不再卡於該齒條部(332)內時，所述卡固片(31)抵於該平面部(331)上，由於所述平面部(331)水平面高於該齒條部(332)，令所述調整件(33)下壓該旋轉件(32)讓所述卡固塊(321)對齊該卡孔(312)，再繼續樞轉所述椅背框(10)則會令該後推部(3351)抵推所述卡固塊(321)，從而旋轉該旋轉件(32)且所述卡固塊(321)卡於該卡孔(312)中，以該卡固塊(321)抵抗所述彈性件(322)的彈力而限制該旋轉件(32)的高度，讓所述旋轉件(32)不再抵推該調整件(33)，此時使用者可反向推動樞轉所述椅背框(10)以調整角度回到原位，此時該前推部(3341)進入所述卡孔(312)內將該卡固塊(321)推離所述卡孔(312)，所述彈性件(322)重新以彈力頂推該旋轉件(32)進而頂推所述調整件(33)，讓所述卡固片(31)繼續卡於該齒條部(332)內，而重返初始狀態。 The actual use situation of the present invention can be seen from the fourth and fifth figures. By pulling the chair back frame (10), the bottom ring (12) can be used as the axis to make the chair back frame (10) face each other. When the chair back frame (20) pivots to adjust the angle of the chair, please see from the sixth figure to the eleventh figure in sequence. When it is in the initial state, the elastic member (322) pushes the rotation with elastic force. The piece (32) then pushes the adjusting piece (33), so that the clamping piece (31) can be stuck in the rack portion (332), thereby fixing the angle of the chair back frame (10), and pivoting Rotate the chair back frame (10) to adjust the angle, so that the chair back frame (11) affects the adjusting piece (33), and the clamping piece (31) can move on the rack portion (332) To adjust and fix the angle of the chair back frame (10), when the chair back frame (10) is continuously pivoted so that the fastening piece (31) is no longer stuck in the rack portion (332) , the clamping piece (31) abuts the flat part (331), and since the horizontal surface of the flat part (331) is higher than the rack part (332), the adjusting member (33) presses down the rotating The component (32) allows the clamping block (321) to align with the clamping hole (312). If the chair back frame (10) continues to pivot, the push-back portion (3351) will push the clamping block. (321), thereby rotating the rotating member (32) and the clamping block (321) is stuck in the clamping hole (312), and the clamping block (321) resists the elastic force of the elastic member (322). Limit the height of the rotating member (32) so that the rotating member (32) no longer pushes against the adjusting member (33). At this time, the user can push the pivoting back frame (10) in the opposite direction to adjust the angle. Return to the original position. At this time, the forward pushing part (3341) enters the clamping hole (312) to push the clamping block (321) away from the clamping hole (312), and the elastic member (322) re-engages. The elastic force pushes the rotating member (32) and then the adjusting member (33), so that the clamping piece (31) continues to be stuck in the rack portion (332) and returns to the initial state.
且，藉由上述結構，由於所述調整件(33)底面於該卡固片(31)一側設有該前推桿(334)，且所述調整件(33)底面於該卡固片(31)另一側設有該後推桿(335)，於推拉樞轉所述椅背框(10)時，由於所述卡固片(31)位於該 前推桿(334)與該後推桿(335)之間而限制所述調整件(33)的位置，從而避免推拉該椅背框(10)過頭的問題。 Moreover, with the above structure, since the bottom surface of the adjustment member (33) is provided with the front push rod (334) on one side of the clamping piece (31), and the bottom surface of the adjustment member (33) is on the side of the clamping piece (31), (31) The rear push rod (335) is provided on the other side.
