Description

座椅
本創作係一種座椅,尤指可調整椅背角度的座椅。
現有座椅為了提高舒適性,會提供椅背的後仰調整功能,讓使用者依據使用需求而調整椅背後仰至一定角度並鎖定,其中,所述椅背與座椅的坐板連接,該坐板的下方設置一底盤,該坐板與該底盤之間設置一轉動裝置及一鎖緊裝置,該椅背係連接該轉動裝置的轉軸,藉由該轉動裝置讓該椅背可調整後仰角度,且藉由該鎖緊裝置鎖定該椅背,以固定該椅背的後仰角度。
然上述中,椅背後仰時,位於轉軸前方的坐板的部分會往上翹起,且位於轉軸後方的坐板的部分會向下傾斜,讓人有種向後下方傾倒的不舒適感。
本創作之主要目的在於提供一種座椅,藉此改善目前座椅的坐板於椅背後仰時,產生往後下方傾斜的不舒適感。
為達成前揭目的,本創作座椅包含:   一椅座,其包含一下座體、一上座體、一後仰調整裝置、一轉軸及一轉動軸,該下座體內形成一裝配空間,並於該下座體的頂面形成一開口,該上座體係可移動地設於該下座體並封閉該開口,該後仰調整裝置設於該下座體的裝配空間,該轉軸設於該下座體並連接該後仰調整裝置,且該轉軸的兩端凸伸出該下座體,該轉動軸係設於該上座體且該轉動軸的兩端出伸出該上座體,以及該轉動軸的軸心平行該轉軸的軸心;以及   一椅背,其係可後仰地設於該椅座,該椅背包含一靠背單元及二連接桿,該靠背單元位於該椅座的後側,該二連接桿設於該靠背單元的兩側,每一連接桿與該轉軸固定,以及與該轉動軸樞接,且每一連接桿於該轉軸及該轉動軸之間形成一朝該椅座前上方延伸的連接部。
上述中,使用者於調整該椅背的後仰角度時,每一連接桿會帶動該轉軸轉動,且朝該椅座前上方延伸的連接部會將該上座體頂起,使得該上座體相對該下座體移動,且朝後上方移動,因此使用者坐在該上座體上時,不會有向後下方傾倒的不舒適感,有效達到提高舒適性的目的,進一步具有簡化結構及便於安裝的優點。
參閱圖1、圖2,為本創作座椅之一較佳實施例,其包含一椅座10及一椅背20。
如圖2、圖4所示,該椅座10包含一下座體11、一上座體12、一後仰調整裝置13、一轉軸14及一轉動軸15,該下座體11內形成一裝配空間16,並於該下座體11的頂面形成一開口,該上座體12係可移動地設於該下座體11並封閉該開口,該後仰調整裝置13設於該下座體11的裝配空間16,該轉軸14設於該下座體11並連接該後仰調整裝置13,且該轉軸14的兩端凸伸出該下座體11,該轉動軸15係設於該上座體12且該轉動軸15的兩端出伸出該上座體12,以及該轉動軸15的軸心平行該轉軸14的軸心。
如圖2、圖3所示,該椅背20係可後仰地設於該椅座10,該椅背20包含一靠背單元21及二連接桿22,該靠背單元21位於該椅座10的後側,該二連接桿22設於該靠背單元21的兩側,每一連接桿22與該轉軸14固定,以及與該轉動軸15樞接,且每一連接桿22於該轉軸14及該轉動軸15之間形成一朝該椅座10前上方延伸的連接部23。
上述中,該椅座10的結構更為簡單,採用該下座體11、上座體12,可縮小體積並便於裝配,進一步參閱圖2、圖3所示,可知椅背20於後仰時,該二連接桿22與該轉軸14一起轉動,且該二連接桿22相對該轉動軸15轉動,藉由所述連接部23帶動該下座體11,讓該下座體11也繞著該轉軸14轉動,且連接部23朝該椅座10前上方延伸,可讓該上座體12整個相對該朝後上方運動,該上座體12不會呈現前部分向上翹起、後部分向下傾斜的狀態,所以使用者坐在該上座體12時,不會有往後傾倒的感覺,進而達到提高舒適性的目的。
如圖4至圖6,該後仰調整裝置13包含一鎖定架131、一可前後移動之鎖舌132、一拉繩134及一彈簧135,該鎖定架131的後側連接該轉軸14,該鎖定架131的前側形成複數上下間隔排列的鎖定孔133,該鎖舌132設於該下座體11並位於該鎖定架131的前方,以及該鎖舌132係可選擇性地伸入其中一所述的鎖定孔133,該拉繩134連接該鎖舌132並延伸出該下座體11,該彈簧135套設於該拉繩134,該彈簧135的兩端分別連接該下座體11及該鎖舌132,另外,所述轉軸14為六角軸,以及該鎖定架131中設有與所述轉軸14配合的六角孔,且所述轉軸14通過該鎖定架131的六角孔,且所述轉軸14與該鎖定架131同動,裝配簡單且受力性能好。
於常態下,鎖舌132配合彈簧135而能伸入該鎖定架131的其中一鎖定孔133中,讓該椅背20鎖定在某個後仰位置,若使用者要調整椅背20的後仰角度時,使用者可通過拉繩134而拉動該鎖舌132,使得該鎖舌132移動出原鎖定孔133,讓椅背20可繞著該轉軸14轉動,且該鎖定架131也隨著該轉軸14一起轉動,待該椅背20調整至新的後仰角度後,使用者可以鬆開該拉繩134,該鎖舌132藉由彈簧135而伸入該鎖定架131的另一鎖定孔133,達到調整及鎖定椅背20後仰角度的目的。
如圖4、圖5所示,該座椅於該下座體11內設置一後仰彈性裝置30,該後仰彈性裝置30包含二彈板31及二阻擋桿32,該二彈板31係間隔設置於該下座體11,並分別位於該鎖定架131的左側、右側,以及每一彈板31的前端固定於該下座體11,每一彈板31的後端為自由端,該二阻擋桿32分別設於該鎖定架131的左側、右側,且分別位於該二彈板31的下方。
於該椅背20後仰時,所述阻擋桿32隨該鎖定架131一起轉動,且阻擋桿32作用在彈板31的下方,使得椅背20在後仰時具有彈性,進而可提高舒適性。
如圖4、圖5所示,該座椅於該下座體11內設置一後仰彈性調節裝置40,該後仰彈性調節裝置40包含一調節軸41、二調節塊42及一調節把手43,該調節軸41係可轉動地設於該下座體11並鄰近該下座體11的後側,該二調節塊42皆係套設於該調節軸41,且分別位於該二彈板31後端的上方並分別抵接該二彈板31,如圖7所示,每一彈板31的表面形成一第一調整面44及一第二調整面45,該調節把手43設於該調節軸41的一端並位於該下座體11外。
其中,該後仰彈性調節裝置40可調節椅背20後仰彈性的大小,由於所述調節塊42具有第一調整面44與第二調整面45,且第一調整面44至調節軸之軸心的距離大於第二調整面45至調節軸之軸心的距離,因此使用者於調整過程中,可以透過該調節把手43轉動該調節軸41,進而帶動所述調節塊42轉動,若調節塊42以第一調整面44與彈板31接觸,則調節塊42將彈板31的自由端向下壓下的距離較大,彈板31的受壓角度加大,彈性力度加大,則彈板31的剛度也較大,若調節塊42以第二調整面45與彈板31接觸,調節塊42將彈板31的自由端向下壓下的距離較小,彈板31的受壓角度減小,彈性力度減小,則彈板31的剛度較小,所以該後仰彈性調節裝置40透過彈板31的剛度以調節椅背20後仰彈性的大小。
上述中,該後仰彈性裝置30設置二彈板31與二阻擋桿32,以及該後仰彈性調節裝置40設置二調節塊42,並且分布於該鎖定架131的兩側,可提高受力均勻度,進而提高穩定性與舒適性。
如圖4所示,該座椅於該下座體11內設置一後仰限位裝置50,該後仰限位裝置50包含二限位阻擋件51,該二限位阻擋件51設於該下座體11且分別位於該二阻擋桿32的上方。
上述中,該後仰限位裝置50係用以限制椅背20最大的後仰角度,可避免後仰角度過大而導致傾倒翻覆,其中,椅背20後仰時,阻擋桿32隨該鎖定架131一起轉動,於椅背20後仰至最大的後仰角度時,阻擋桿32會受到限位阻擋件51的組擋而無法繼續後仰,故安全性佳。
此外,該座椅於該椅座10的下座體11底面可設置一椅腳60,以及可於該二連接桿22上分別設置一扶手70。
