該升降座10係可裝卸地設於該椅背2上，如圖4、5所示，該升降座10內部設計了多個導槽包含有一斜入口導槽11、一主直導槽12、一彎引導槽13及多個階梯導槽14。 The lifting base 10 is detachably disposed on the seat back 2, as shown in FIGS. 4 and 5. The inside of the lifting base 10 is designed with a plurality of guiding grooves including a slanting inlet guiding groove 11 and a main straight guiding groove 12. A curved guiding groove 13 and a plurality of stepped guiding grooves 14 are formed.
如圖4、5所示，該斜入口導槽11係位於該升降座10的軸向中 心(如圖3、5之Y軸線所示)所區隔之一邊的近頂部處，並由該升降座10的頂部向下延伸；該主直導槽12係位於該斜入口導槽11同一邊且由該升降座10的上部向下延伸至下部；該彎引導槽13係位於該斜入口導槽11的下部與該主直導槽12的上部之間，使該斜入口導槽11與該主直導槽12得以連通，如圖5、6所示，其中該彎引導槽13的導槽底面朝向該斜入口導槽11的底面進一步形成一下降斜坡131，而其朝向該主直導槽12的底面進一步形成一具有落差(如圖6之高度H所示)之一陡降坡132；及該多個階梯導槽14其係由該主直導槽12的相對另一邊的該升降座10的下部至上部依序排列，其中各階梯導槽14具有一停止槽點15，而位在最上方的該階梯導槽14的上部與該主直導槽12的上部連通並定義一上端槽點16，而位在最下方的該階梯導槽14的下部與該主直導槽12的下部連通並定義有一下端槽點17。 As shown in FIGS. 4 and 5, the oblique inlet guide groove 11 is located in the axial direction of the lifting base 10. The heart (shown in the Y-axis of Figures 3 and 5) is located near the top of one of the sides and extends downwardly from the top of the lifting base 10; the main straight guiding channel 12 is located at the oblique inlet guide 11 One side is extended downward from the upper portion of the lifting base 10 to a lower portion; the curved guiding groove 13 is located between the lower portion of the inclined inlet guiding groove 11 and the upper portion of the main straight guiding groove 12, so that the oblique inlet guiding groove 11 is The main straight guide groove 12 is connected, as shown in FIGS. 5 and 6, wherein the bottom surface of the guide groove of the curved guide groove 13 further forms a descending slope 131 toward the bottom surface of the oblique inlet guide groove 11, and the main guide is directed toward the main direct guide. The bottom surface of the groove 12 further forms a steep slope 132 having a drop (as shown by the height H of FIG. 6); and the plurality of step guides 14 are lifted by the opposite side of the main straight guide 12 The lower portion to the upper portion of the seat 10 are sequentially arranged, wherein each step guide groove 14 has a stop groove point 15, and an upper portion of the step guide groove 14 located at the uppermost portion communicates with an upper portion of the main straight guide groove 12 and defines an upper end. a groove 16 and a lower portion of the stepped guide groove 14 communicating with the lower portion of the main straight guide groove 12 and defining a lower end groove Point 17.
該升降座10進一步與一定位件50鎖固成一體，但非用以限制本發明，該定位件50具有一卡扣直桿51及一卡扣橫桿52，使該定位件50的卡扣直桿51及卡扣橫桿52進一步可夾固在該椅背2的一框架201的上部，且能夠應用於各種不同形狀大小的該椅背2。 The lifting base 10 is further integrally locked with a positioning member 50, but is not used to limit the present invention. The positioning member 50 has a buckle straight rod 51 and a buckle cross rod 52, so that the positioning member 50 is buckled. The straight rod 51 and the snap rail 52 are further clamped to the upper portion of a frame 201 of the seat back 2, and can be applied to the seat back 2 of various shapes and sizes.
該頭枕底直支20之上端連結一頭枕3以使該頭枕3得隨該頭枕底直支20同步升降滑動，該頭枕底直支20具有一直滑槽21供可裝卸地設於該升降座10上，當該頭枕底直支20與該升降座10結合成一體時，該升降結構1與該椅背2即結合成一體。 The headrest 3 is connected to a headrest 3 at the upper end of the straight bottom support 20 so that the headrest 3 can slide up and down with the straight bottom 20 of the headrest. The headrest bottom 20 has a straight chute 21 for removably The lifting structure 1 is integrated with the seat back 2 when the headrest bottom 20 is integrated with the lifting seat 10.
該彈性定位桿30之上端係固設於該頭枕底直支20的直滑槽21內的軸向中心(如圖3、5之Y軸線所示)上，其下端係形成一定位端31，該定位端31得藉該彈性定位桿30之材料彈性以彈性保持在該直滑槽21內的 軸向中心(如圖3、5之Y軸線所示)上，使得該定位端31得藉彈性力在軸向中心(如圖3、5之Y軸線所示)上左右擺動(如圖3之X箭頭方向所示)。 The upper end of the elastic positioning rod 30 is fixed on the axial center (shown by the Y-axis of FIGS. 3 and 5) in the straight sliding slot 21 of the straight bottom 20 of the headrest, and the lower end is formed with a positioning end 31. The positioning end 31 is elastically retained in the straight chute 21 by the material elasticity of the elastic positioning rod 30. The axial center (shown in the Y-axis of FIGS. 3 and 5) is such that the positioning end 31 is oscillated left and right at the axial center (shown by the Y-axis of FIGS. 3 and 5) by the elastic force (as shown in FIG. 3). The direction of the X arrow is shown).
該頭枕底直支20的直滑槽21內進一步設有一穩定件40，但非用以限制本發明，該穩定件40具有一固定孔41及一固定槽42，使該彈性定位桿30的上端能嵌設並固定在該固定孔41內，並使該彈性定位桿30的一上段局部32得嵌入固定於該固定槽42中以使該彈性定位桿30得藉材料彈性以保持在該升降座10之軸向中心(如圖3、5之Y軸線所示)上。 A stabilizing member 40 is further disposed in the straight chute 21 of the straight bottom support 20 of the headrest. However, the stabilizing member 40 has a fixing hole 41 and a fixing groove 42 for the elastic positioning rod 30. The upper end can be embedded and fixed in the fixing hole 41, and an upper portion 32 of the elastic positioning rod 30 can be embedded and fixed in the fixing groove 42 so that the elastic positioning rod 30 can be elastically held by the material to maintain the lifting The axial center of the seat 10 (shown as the Y-axis of Figures 3 and 5).
參考圖2-5，當該頭枕底直支20組裝於該升降座10上時，該彈性定位桿30的定位端31得藉材料彈性彎曲(如圖3之X箭頭方向所示)離開軸向中心(如圖3、5之Y軸線所示)而導入該升降座10的斜入口導槽11內，如圖5、6所示，該定位端31再向下滑動並藉彈性向軸向中心(如圖3、5之Y軸線所示)回復(如圖3之X箭頭方向所示)往該彎引導槽13的下降斜坡131斜上爬去，並越過該陡降坡132而導入至該主直導槽12內，因該陡降坡132朝向該主直導槽12的底面具有高低落差(如圖6之高度H所示)，使該定位端31位在低於該陡降坡132的該主直導槽12底面上而不易再反向滑回該斜入口導槽11。 Referring to FIGS. 2-5, when the headrest bottom 20 is assembled on the lifting base 10, the positioning end 31 of the elastic positioning rod 30 is bent by the material elastic (as indicated by the arrow X in FIG. 3). Introduced into the inclined inlet guide groove 11 of the lifting base 10 toward the center (shown by the Y-axis of FIGS. 3 and 5), as shown in FIGS. 5 and 6, the positioning end 31 slides downward again and is elastically axially The center (shown in the Y-axis of FIGS. 3 and 5) is restored (shown by the direction of the arrow in FIG. 3) and climbs obliquely toward the descending slope 131 of the curved guide groove 13, and is introduced over the steep slope 132. In the main straight channel 12, the steep slope 132 has a height difference (as indicated by the height H of FIG. 6) toward the bottom surface of the main straight channel 12, so that the positioning end 31 is located below the steep slope. The bottom surface of the main straight guide groove 12 of 132 is not easily slid back to the oblique inlet guide groove 11.
參考圖1、4、5，其中當該彈性定位桿30的定位端31導入至該升降座10的主直導槽12內之後，該定位端31再沿著該主直導槽12而向下滑動至停止在該下端槽點17(如圖1、5之位置A所示)上。 Referring to FIGS. 1, 4, and 5, after the positioning end 31 of the elastic positioning rod 30 is introduced into the main straight guide groove 12 of the lifting base 10, the positioning end 31 is further down along the main straight guiding groove 12. Slide to stop at the lower slot point 17 (shown as position A in Figures 1, 5).
當該頭枕底直支20被拉動而使該定位端31同步向上滑動時，該定位端31得離開該下端槽點17(如圖1、5之位置A所示)而沿著最下方的該階梯導槽14並滑動至停止於該階梯導槽14的停止槽點15(如圖1、5 之位置B所示)上以形成一最低之高度位置。 When the straight bottom 20 of the headrest is pulled to slide the positioning end 31 synchronously upward, the positioning end 31 is separated from the lower end slot 17 (as shown by position A in FIGS. 1, 5) and along the lowermost portion. The stepped guide groove 14 slides to a stop slot 15 that stops at the stepped guide groove 14 (see FIGS. Position B is shown) to form a lowest height position.
藉由上述的相同操作方式，同理可使該定位端31從下一階梯導槽14之“B”停止槽點15滑動並停止在上一階梯導槽14之“C”停止槽點15；或從“C”停止槽點15滑動並停止在上一階梯導槽14之“D”停止槽點15；或從“D”停止槽點15滑動並停止在上一階梯導槽14之“E”停止槽點15上，藉以完成高度位置之調整。 By the same operation mode as described above, the positioning end 31 can be slid from the "B" stop slot 15 of the next step guide groove 14 and stopped at the "C" stop slot point 15 of the previous step guide groove 14; Or slide from the "C" stop slot 15 and stop at the "D" stop slot 15 of the previous step guide 14; or slide from the "D" stop slot 15 and stop at the "E" step guide 14" "Stop the slot 15 to complete the adjustment of the height position.
當繼續拉動該頭枕底直支20使該定位端31從“E”停止槽點15滑動至最上方的該上端槽點16(如圖1、5之位置F所示)時，該定位端31藉材料彈性而直接沿著該階梯導槽14可向下滑動至進入該主直導槽12內並滑動至停止在下端槽點17(如圖1、5之位置A所示)上，藉此可進行下一次的該頭枕3高度位置滑動調整作業。 When the headrest bottom 20 is continuously pulled to slide the positioning end 31 from the "E" stop slot 15 to the uppermost upper slot point 16 (shown as position F in FIGS. 1, 5), the positioning end 31, by means of material elasticity, can slide down directly along the stepped guide groove 14 into the main straight guide groove 12 and slide to stop at the lower end slot point 17 (shown in position A of FIG. 1, 5). This allows the next headrest 3 height position slide adjustment operation to be performed.
本發明之一種椅子頭枕之升降結構1，與其他先前技術如比較，具有以下優點： The lifting structure 1 of the chair headrest of the present invention has the following advantages as compared with other prior art:
