Abstract

一种可调整高度的椅子扶手,包括:其下端固装 于椅子坐垫底部,上端在不同高度开设多个卡槽的撑 架;内部中空并套设于撑架上端外部,其上端内壁设 有一对枢槽的动作套体,以及杠杆体,该杠杆体两侧 适当位置凸设有一对枢轴,并于上、下端分别设有外 凸的受压部及下伸的卡制片,卡制片末端内面凸设卡 钩,受压部露出于动作套体上端外侧,二枢轴则对应 枢装于上述动作套体的二枢槽上,并以其卡钩选择性 地卡入撑架上的卡槽中。

Description

本实用新型涉及一种椅子扶手,特别是一种可调整高度的椅子扶手。
以往可调整坐垫高度与靠垫高度的椅子,如图1所示,椅子的坐垫91两侧装设一对扶手911,下端则藉固设螺杆92而螺装于脚架93上,于是当旋动坐垫91(螺杆92),使其与脚架93相对旋转时,整体坐垫91便可上升或下降位移;另外,靠垫94高度的调整,由于是藉旋紧旋钮941夹设夹片组942,而夹固于由坐垫91底部往上延伸的支撑架95上端,其欲作高度调整时,只要旋松旋钮941使夹片组942松动,整体靠垫94便可上、下位移至所需高度后,重新旋紧旋钮941再度使靠垫94夹固于支撑架95的预定高度上。
上述椅子的坐垫91、靠垫94具有高度调整功能,使得坐靠者可就身材与坐靠习惯的差异,而调整坐垫91、靠垫94的高度,而获得较舒适的坐靠状态;然而在一般使用者实际坐靠时,不难发觉,除坐垫91、靠垫94高度有调整需要外,坐椅子时常须以双手手肘抵于扶手911上,扶手911高度若无法作适度的调整也会影响其舒适感。
本实用新型的目的,在于提供一种可调整高度的椅子扶手,使其配合装设于椅子上时,使坐靠者更加舒适。
本实用新型的技术措施是将椅子扶手分为可活动连接的几个部分:撑架、动作套体、杠杆体;
本实用新型的可调整高度的椅子扶手,包括下端固定于椅子座垫底部,上端开设有至少二个卡槽的撑架、套设于撑架上端的动作套体以及用以调整高低位置的杠杆体;所述撑架与杠杆体分别插装于动作套体内部的内、外侧,使杠杆体适当位置枢设于动作套体内,而其上、下端则分别设有露出动作套体外部的受压部及末端设有卡钩的卡制片,且该卡制片的卡钩可卡入撑架在不同高度所开设的多个卡槽中的一个,所以当向内压杠杆体的受压部时,使其下端卡制片的卡钩摆离撑架的卡槽,使动作套体自由移动调整至合适高度,并藉卡钩选择性地卡入另一对应的卡槽而获定位。
本实用新型的效果:本实用新型的可调整高度的椅子扶手,配合装设于椅子上时,可根据乘坐者的需要灵活调整其高度,使乘坐者更加舒适,所以确实为一种实用性强的装置。
现在举出较佳可行实施例,并配合附图详述如下:
图式的简单说明:
图1是一种以往椅子的立体示意图;
图2是本实用新型实施例可调整高度的椅子扶手的立体分解示意图;
图3是本实用新型实施例可调整高度的椅子扶手的侧面剖视图;
图4是本实用新型实施例可调整高度的椅子扶手的立体组合示意图;
图5是本实用新型实施例可调整高度的椅子扶手在可自由调整高度时的剖面示意图。
如图2所示,本实用新型实施例的可调整高度的椅子扶手,可配合装设于一般椅子的坐垫两侧底部,而由于一般椅子坐垫的设置方式,在上述以往椅子构造中已详述,在此不再重复,仅就该可调整高度的椅子扶手部份的组成详作说明:如图所示,该可调整高度的椅子扶手包括:
撑架1,呈板片状,其下端往内弯折并开设有数个螺孔11,可藉螺钉而锁固于一般椅子的坐垫底部,其上端外侧面则由上而下开设有一列凹入的卡槽12。
动作套体2,内部呈中空状且上下贯通,并藉其中一对内壁以中央预留间隙的方式成型诸多对应设置的肋片21、22,而将上述撑架1上端插设于各肋片21、22之间,且动作套体2顶部有一框围23,该框围23的内缘设有一对固定孔231,可藉一对螺钉232锁固,而令整体动作套体组装于垫体3底部,且框围23外侧开设有缺口24,并于缺口24中间成型连设有一对辅助弹片25;此外,在动作套体2另一对内壁上,藉由向外凸出适当壁厚而形成一对开口朝上的枢槽26。
杠杆体4可对应插装于上述动作套体2内部偏外侧,于两侧适当位置则凸设有一对枢轴41,可对应跨架于上述动作套体2的二枢槽26上,并于上、下端分别设有往外凸出的受压部42及往下延伸的卡制片43;其中,受压部42底部开设有腔室421,腔室421可对应套设于动作套体2的二辅助弹片25外部;卡制片43的末端内面凸设有卡钩431,可选择性地卡入上述撑架1上所凹设的诸多卡槽12中的一个。
藉上述构件的组合,如图3所示,其中撑架1上端插装于动作套体2中成对的各肋片21、22间,而杠杆体4则以其二枢轴41跨架枢装于动作套体2的二枢槽26上,且其往下延伸的卡制片43位于撑架1外侧,并以末端的卡钩431卡入撑架1外侧面的卡槽12中,又因杠杆体4往上受垫体3阻挡而无法上移,往下则因其枢轴41跨架于动作套体2的二枢槽26而无法下移,也就是整体动作套体2、杠杆体4、垫体3三者组装为一体(其整体组合的外观立体图如图4所示),又由于卡制片43末端的卡钩431是卡入于撑架1的卡槽12中,所以此时组装一体的动作套体2、杠杆体4、垫体3三者是处于受撑架1卡制定位在预定高度的状态。
当操作该动作套体2、杠杆体4、垫体3三者以调整高度时,如图5所示,内压杠杆体4上端的受压部42,使整体杠杆体4以枢轴41为支点作杠杆式摆动,也就是受压部42端将往内摆动,而其下端的卡制片43则往外摆动,使其末端的卡钩431往外摆离撑架1的卡槽12,此时动作套体2、杠杆体4、垫体3三者便已脱离被撑架1卡制定位的状态,而可自由上下位移进行高度调整,并于调整至合适高度时,解除内压杠杆体4上受压部42的施力,使其卡制片43下端的卡钩431,回复至卡入于撑架1的卡槽12的状态,而重新获得不同高度的定位,藉此达到其高度调整的目的。
又当内压杠杆体4的受压部42往内摆动时,由于受压部42是套覆于动作套体2的辅助弹片25外部,因此辅助弹片25将略为受压而往内弹性变形(因其是以略具弹性的塑料所制成),而藉此弹性变形所积蓄的弹力,当内压受压部42的施力消失时,整体杠杆体4一方面可藉其卡制片43较上端与撑架1抵靠处抵撑所积蓄的弹力,另一方面可藉该辅助弹片25弹性变形所积蓄的弹力而回复定位。
