Description
技术领域
本实用新型涉及的是办公椅椅背倾仰时的坐垫连动装置,通过该装置让椅背倾仰而带动坐垫稍向前位移、并同时令坐垫后侧稍向下降,如此不但让乘坐者身体重心前移而更能保持稳定以外,并且让向后倾仰动作的施力更为省力,同时也令来回倾仰的动作形成一种如摇椅般舒适的摇动作用。
背景技术
一般椅具在乘坐时,其椅背大多可以进行弹性的倚靠与倾仰,且现有椅背可倾仰活动的椅具,是当乘坐者位于坐垫上而令其倚靠在椅背上的背部向后仰躺时,椅背连同坐垫会一起产生向后翻仰的动作,并当坐垫向后翻转时,容易导致乘坐者整个身体的重心向后移动,进而造成瞬间的向后翻仰的动作,令乘坐者发生失去重心的错觉,造成乘坐者惊吓而有欲起身抬腿的反射动作,如此反而更令其重心不穏,进而造成由椅上跌落的危险情事发生。
另外,乘坐者在向后仰躺时,双脚通常着地支撑住而稍微施力,再加上身体后仰动作以外,同时腰部也要稍为用力,如此多重动作的同时执行,让乘坐者必须较为耗力,方可顺利的向后仰动。
其次,乘坐者若欲放松身体而进行前后的来回倾仰动作时,整个乘坐部位只能以一个支点做前后的摆动,导致乘坐者整个身体,仅只能进行单调的前后摆动,其舒适性不足。
实用新型内容
缘是,为了改善上述已知办公椅在乘坐都进行向后倾仰时,可能突然发生失去重心的不安定感、后仰施力较为耗力、以及乘坐部位来回摆动单调等问题,本实用新型即提供一种坐垫与椅背之间的连动装置,是通过链接椅背的椅背支座前上端枢固在一底座上,并在底座的前下端与椅背支座的稍中间处分别设有其上端枢固于坐垫背面前后的前、后连件,同时椅背支座的前下端穿设一伸入底座内的轴杆,并在底座内设一弹力顶推住该轴杆的弹力顶推单元,且在前连件与轴杆之间枢固连结连动件,让椅背向后倾仰时,坐垫会稍微前移、并令其后端稍向下沉降,进而使得乘坐者重心前移而增加乘坐仰躺时的稳固与安全,同时也令仰躺时的施力更为轻松容易,且让整乘坐的部位具有前后摇动的舒适性。
本实用新型解决其技术问题所采用的技术方案是:是一底座的稍后侧上端处与一其后端具有椅背连结部的椅背支座的前上端枢固在一起,并令椅背支座的前下端处穿固一轴杆伸于底座内,且令底座内设一朝着该轴杆弹力顶推的弹力顶推单元,复设两相对的前连件下端枢固于底座的前下端两侧,然后再设两相对连动件的两端,分别枢固在两前连件的略中间处与前述轴杆两侧之间,并令椅背支座两侧的略中间上端处枢固两相对的后连件,进而令两前连件与两后连件的上端分别枢固于坐垫背面的前后处。
本实用新型的有益效果是,通过上述背椅与坐垫之间的连动装置,让椅背倾仰时可以连动坐垫的前移与后倾,让乘坐者后仰的施力更为轻松、且重心前移而使得仰躺更为平穏安全与舒适。

图2是本实用新型的立体分解示意图。
图3是本实用新型的侧面剖视图。
图4是本实用新型的倾仰作动的示意图。
图中:1.底座、11.后导槽孔、12.前导槽孔、2.椅背支座、21.椅背连结部、3.坐垫、31.前枢固座、32.后枢固座、4.椅背、5.弹力顶推单元、51.顶抵座、61、62、63.轴杆、71.前连件、72.后连件、8.连动件。
具体实施方式
请参阅图1至图3所示,本实用新型是一供装设椅脚、以及一具有坐垫3与椅背4的乘坐部位的底座1,且令底座1稍后侧的上端处通过一轴杆63与一椅背支座2的前侧上端枢固连结,并令椅背支座2的后端设有可供椅背4下端固定连结的椅背连结部21,同时又令椅背支座2的前下端轴穿另一轴杆61,并令该轴杆61穿伸入底座1内,同时底座1供轴杆61的穿合处开设一后导槽孔11,让轴杆61可沿着后导槽孔12移动、且令其移动的角度受到囿限,复在椅背支座2的上端稍中间处枢固有两相对的后连件72,令后连件72的上端可以与坐垫3背面稍后侧处固定的后枢固座32枢固连结在一起。
又,在底座1内的前处装设一弹力顶推单元5,令该弹力顶推单元5的后端设一受弹簧向外弹力顶推的顶抵座51,并让顶抵座51抵靠在前述轴杆61的中间处,使得椅背支座2以轴杆63处为支点而产生向上摆转之势。
另,设两相对的前连件71的下端枢固于底座1的前端稍下两侧,且设两相对的连动件8的前端,分别通过轴杆62与两对应前连件71的稍中间处枢固连结在一起,且两连动件8是装设在底座1内侧的两边,并令轴杆62是穿过底座1上开设的前导槽孔12后,再与前连件71结合,复又令两前连件71的上端枢固于坐垫背面前侧处固定的前枢固座31上,同时两连动件8的后端又枢固在椅背支座2的前下端处穿设的轴杆61上。
是以,请参阅图3、4所示,当乘坐者乘坐在办公椅的坐垫上、且背部倚靠在椅背4上后,若其身体向后仰动时,椅背4会向后倾仰摆动,即让椅背支座2的后端向下摆转而沉降,令其上的两后连件72拉动坐垫3的后侧向下位移,且再加上坐垫3承受乘坐者重量向下压迫的施力作用,向下摆转的椅背支座2前下端处穿设的轴杆61,令两连动件8朝前移动,进而带动两连动件8前端枢固连结的两前连件71朝前摆转,使得坐垫3产生向前位移的动作。
同时,前述的弹力顶推单元5亦会对轴杆61产生弹性的反推,进而令椅背4具有来回弹性的摆动作用,故令乘坐者向后倾仰的倚靠倍感舒适以外,更令乘坐者进行前后的摇摆时,因坐垫3同时进行了前后移动、以及前后倾仰的动作,让乘坐在办公椅上的乘坐者可以感受到尤如乘坐摇椅般的摇动与摆动的动作,令摇摆的舒适性更为提高,让乘坐者的身体更容易放松而获得休息。
另外,在乘坐者向后仰而欲进行仰躺休息时,坐垫3的朝前移动动作,让乘坐者整个身体的重心略为前移,使得后仰的动作较为缓和,可避免乘坐者发生突然失去重心的不平衡感,同时也可以增加乘坐者向后仰时的平穏度,确保乘坐的安全性。
此外,在乘坐者后仰时,因坐垫3的后侧端因沉降而略呈后倾状,让乘坐者臀部受到支撑阻挡,而不会发生向前滑动的动作,也可以减少腿部辅助后仰时的施力,进而令乘坐者后仰的动作,更为容易与省力。
