Description

调整椅背仰靠角度的装置
技术领域
本实用新型是在椅具基座上设一可以摆转拨动的操控杆末端,设有可被拨动滑移伸缩的定位片,使能通过由定位片可嵌入或退离座垫底面所固定的底盘后端所设的任一位置的嵌制口中,进而调整椅背的仰靠角度。
背景技术
关于公告第四九六一三三号专利是一控制椅背倾仰的装置,为一椅具的椅脚上端的气压棒末端,穿设于一底座内,并使底座上设一固定座垫的底盘,且使固定座与底盘之间枢接在一起,且又在底盘的后端向下伸设复个卡制槽,然后在底座上设一具有可容设定位片的槽穴的导座,并在导顶面滑设一滑座,且在导座与滑座顶面分别设一直形及斜形的长孔,然后以螺丝穿过各长孔后螺固于槽穴内的定位片上。
乃令滑座侧边伸设一穿设有往复杆的耳部,并在往复杆两侧各套设有弹簧,且令两边弹簧的外侧端皆受到往复杆杆未的止挡体所挡止,复再使往复杆的一端固定在操控椅背倾仰的操控杆上;故当推拉操控杆时,即能带动滑座移动,进而通过由弹簧及斜形长孔的弹性预力顶推下,使定位片由槽穴伸出或退缩,以达定位片嵌入或退出底盘末所设的卡制槽上,来调整椅背的倾仰角度。
不过,由于弹簧迫使滑座移动的力量,正好与定位片移动的方向垂直,而顶推定位片移动的长孔是呈斜设状,所以使定位片移动的力量几乎只有弹簧推动滑座移动力量的一半,又加上滑座与导座之间的摩擦力、定位片与槽穴之间的摩擦力时,更锐减了推动定位片移动的力量。
因此,造成定位片非常容易卡于槽穴内而无法移动,,虽然可以在增加弹簧的弹力,来增强推动定位片的力量,但却也会增加使用推动操控杆所须的力量,进而增加操作的负荷,而又因操控杆的操作方式施力方向,弹簧的反作用力方向,为同一轴向,造成操控杆本身在操作上就较为不顺手与施力不易,如果再加上推动操控杆的力量增加的情况下,更增加操作上的困难。
实用新型内容
为了使定位片的移动更为顺畅无阻,且又令操作者更能轻盈简单地操作,乃为本实用新型所极欲解决的课题,故本实用新型是令操控杆改为摆动的杠杆省力方式,使其达成简易操作的目的外,且又能大幅增进推动定位片移动的力量。
本实用新型又令顶推定位片的弹簧的施力方向,使与定位片的伸缩移动的方向相同,乃令弹簧对定位片的顶推力量,可以完全作用于定位片上而不会发生减少的情形,进而令定位片的伸缩移动更为顺畅。
所以,本实用新型为达上述的目的而所采行的技术手法,是令操控杆中间预定处枢固于基座上,且又枢固一具两弹性脚的弹性元件,使其中一弹性脚挂于操控杆末端,另一弹性脚则是勾挂于滑设于基座的定位片上,并令该弹性脚的顶推施力方向与定位片伸缩移动的方向呈互为垂直,故当操控杆被推动而令其末端摆动时,即能带动弹性元件转动而令其中一弹性脚对定位片顶推或回拉,进而令定位片做伸缩移动而嵌入或退离出底盘后下方所设的任一位置的卡制槽。
一种调整椅背仰靠角度的装置,是包括一基座与底盘中间处枢固在一起,并在基座后端顶面容设一可前后滑移的定位片,并使定位片前端伸出后,可以伸入底盘后端底面所设的任一卡制槽内,设一操控杆中间预定处枢固于基座上,使操控杆的末端部可以自由摆动,并在定位片上固设一杆体,而又枢固一可以自由转动且具有两弹性脚外伸的弹性元件,乃令其中一弹性脚固于操控杆的末端部上,另一弹性脚则可勾固于定位片上所设的杆体上;
故当操控杆被拨推而令末端部来回摆动时,即能使弹性元件发生转动的预力,进而对定位产生不同方向顶推的预力,使定位片可伸缩移动而嵌入或退离出底盘后端所设的任一卡制槽中。
所述的调整椅背仰靠角度的装置,其中在位于操控杆中间处的基座上固设一卡制体,并令卡制体上设有可供操控杆杆体穿过的容槽,同时又令容槽中间呈略小于操控杆杆体的弹性挡止凸部。
所以,本实用新型可通过由下列的实施例并配合附图,而获得充分的了解,并据以实施。
附图说明
图1是本实用新型的立体分解示意图;
图2是本实用新型的俯视示意图;
图3是本实用新型的侧面剖视示意图;
图4是本实用新型的卡制体的局部示意图;
图5是本实用新型的定位片退离卡制槽的示意图;
图6是本实用新型的靠背倾仰调整动作示意图。
具体实施方式
敬请参阅图1、2及3所示,本实用新型是为一椅脚上端设一基座1,而椅的座垫式面则固设一底盘2,并使基座1与底盘2之间的中间处枢固在一起,然后又于基座1的后端处与一摆架4的前端41的穿孔42枢固在一起,并再使摆架4中两侧壁所设的穿孔43,与底盘2后端两边伸设的连臂23又枢固在一起,同时在底盘2的后端底面中间向下固设一定位体21,而在定位体21上开设有复数列卡制槽22。
另外,设一操控杆3的一端伸出于基座1外,并令操控杆3中间预定处31枢固一固定座11上,然后再使固定座11固定于基座1上,且使操控杆3中间穿过一固定在基座1中的卡制体7(请配合图4所示),而该卡制体7上是设有可容设操控杆杆体35的容槽71,并令容槽71中间间距设有较操控杆杆体35小的挡止凸部72,同时令在位于容槽71处设镂空状,而令中间处形成一弹性部73,乃令挡止凸部72处具有较佳的弹性嵌制作用,而提供杆体35在容槽71两端之间顺畅的移动与定位。又,操控杆3续前伸而形成一具有穿孔的末端部32,而基座1的后端中间处设一滑槽10,而在滑槽10中设一滑动的定位片5,然后再设一顶面设有长形孔13的覆盖12,将定位片5覆盖住而使定位片5可以前后滑移,并令其前端可以伸出于外而能伸入底盘2后端的任一卡制槽22中;同时,再令定位片5的顶面固设杆体51,并使杆体51由覆盖12的长形孔13穿出,然后又设一弹性元件8枢固于覆盖12上而能自由转动,且令弹性元件8设有两弹性脚81,82,乃令其中一弹性脚81是勾固于操控杆3末端部32的穿孔中,而弹性脚82的另一端则是勾固于杆体51上。
因此,请参阅图5、6所示,当操控杆3的外侧端受到拨推时,其中间杆体35部位会由卡制体7的容槽71的一端而嵌入另一端,进而令杆体35部位受到中间的挡止凸部72的弹性挡止而定位,同时操控杆3的末端部32则会发生摆移,迫使弹性脚81被向外拨张,使弹性元件8发生转动的预力,进而令另一端的弹性脚82产生将定位片5向左拨的预力;故当椅子的靠背稍受到前后的压迫及释放的来回作用时,原来受卡制槽22嵌夹紧固的定位片5则会发生松动的间隙,让定位片5在弹性脚82的预力顶推下而退出卡制槽22,进而令椅子的靠背可以依照乘坐所须而调整至所须的仰靠角度后,再将操控杆3反向拨推,而令其末端部32摆转回来原来垂直状态的位置,而此刻弹性脚82则会对杆体51产生向右顶推的预力,所以当靠背摆至预定的倾斜度而使定位片5对准欲嵌入的卡制槽22时,就会令其前端弹入卡制槽22中,而将靠背卡制住。
所以,将操控杆3改为摆动式拨推方式,且又为杠杆省力结构,而能大幅增进推动定位片5移动的力量,乃令操作的操作更为省力,且使操作更为简单容易;同时,由于顶推定位片5的弹性元件8的弹性脚82的施力方向,正好与定位片5的伸缩移动的方向相同,故令弹性脚82顶推力量,可以完全作用于定位片5上,而不会发生减少的情形,进而令定位片5可受到更大力量的顶推,而能更顺畅的伸缩滑移。
尽管,上述的实施例已对本实用新型有较佳的具体化的揭露与详述,皆为熟悉该项技术人士所能清楚了解,而其所做的各种形状及局部的改变,应都是没有脱离本实用新型范畴。
