实施例1
参照图1至图5所示，本实施例提供一种户外用的折叠椅，其具有如图1所示的展开状 态和如图5所示的折叠状态。该折叠椅包括：上铰接座11、多个支撑腿12、下铰接座13和多个上支杆14。该折叠椅还包括支撑布套，支撑布套连接于多个上支杆14上，构成支撑臀部的座椅部分，还可进一步构成支撑背部的靠背部分。折叠椅在展开状态时，布套被多个上支杆14撑开，以支撑人体。
进一步地，上铰接座11包括多个径向向外延伸的上铰接部111，多个上铰接部111沿上铰接座11的圆周方向间隔分布。各个支撑腿12分别具有可转动地连接于上铰接座11的上端部121和用于撑在地面上的下端部。上铰接部111具体为铰接槽，该铰接槽具有开放设置的下侧和外侧，以和支撑腿12铰接；其中，支撑腿12的上端部121插于该铰接槽中并相互铰接。此处，方位词“外侧”是以上铰接座11的几何中心为参照定义的，以距上铰接座11的几何中心较远的一侧为外侧。
下铰接座13位于上铰接座11的下方，上铰接座11和下铰接座13可直接或间接连接；本实施例中，上铰接座11和下铰接座13通过下述的连杆16间接连接。各上支杆14的下端部可转动地连接于下铰接座13。下铰接座13具体为铰接槽，该铰接座具有开放设置的上侧和外侧，以和上支杆14相铰接；其中，上支杆12的下端部插入该交接槽中并相互铰接。此处，方位词“外侧”是以下铰接座13的几何中心为参照定义的，以距下铰接座13的几何中心较远的一侧为外侧。
每个支撑腿12的中部还分别和一对应的上支杆14相转动连接，多个支撑腿12和多个上支杆14交错设置。具体地，上支杆14具有连接套143，连接套143和支撑腿12相转动连接。
更进一步地，参照图1和图2所示，下铰接座13具有第一下铰接部131和第二下铰接部132，第一下铰接部131高于第二下铰接部132，相邻两个支撑腿12之间仅设置一个第一下铰接部131或一个第二下铰接部132，在俯视视角下，第一下铰接部131或第二下铰接部132位于相邻两个上铰接部111之间。
多个上支杆14包括两个前撑杆141和两个靠背杆142，各前撑杆141的下端部和第一下铰接部131转动连接，各靠背杆142的下端部和第二下铰接部132转动连接，这使得前撑杆141的倾斜程度小于靠背杆142的倾斜程度，更符合人体工学，在使用折叠椅时会比较舒适。
还需要说明的是：任意相邻两个上铰接部111之间形成有上收容槽，折叠椅在折叠状态后，上支杆14向上铰接座11靠近，并被收容在上收容槽中；类似地，相邻第一下铰接部131 之间、相邻第二下铰接部132之间、第一下铰接部131和第二下铰接部132之间分别形成有下收容槽，折叠椅在折叠状态后，支撑腿12向上铰接座11靠近，并被收容在下收容槽中。此外，上述提及的“转动连接”具体是枢轴连接。
各支撑腿12的下端部设置有脚垫17，脚垫17具有支撑表面171，折叠椅在展开状态时，各脚垫17的支撑表面171位于同一平面内。
各前撑杆141、靠背杆142或支撑腿12为伸缩杆。具体地，参照图1所示，前撑杆141包括两个相套接且能够相对伸缩的杆件15，靠背杆142包括三个相套接且能够相对伸缩的杆件15，支撑腿12包括两个相套接且能够相对伸缩的杆件15，由此该折叠椅能够适应性的调整高度，且在折叠收纳之后，体积较小。
参照图3和图4所示，上铰接座11和下铰接座13中的一者上设置有一连杆16，另一者和连杆16可拆卸地连接。具体到本实施例中，上铰接座11上设置有连杆16，下铰接座13和连杆16可拆卸地连接。上铰接座11或下铰接座13上设有供连杆16插入的插接槽133，具体到本实施例中，下铰接座13上设有插接槽133，连杆16的下端部可脱离地插接于该插接槽133中。
该折叠椅在展开状态时，多个支撑腿12的下端部相对展开，多个上支杆14的上端部相对展开，连杆16连接于上铰接座11和下铰接座13之间；具体地，连杆16的下端部插于下铰接座13的插接槽133中。该折叠椅在折叠状态时，多个支撑腿12的下端部相互靠拢，多个上支杆14的上端部相互靠拢，连杆16和下铰接座13相分离，上铰接座11和下铰接13座相互分离；具体地，连杆16的下端部脱离下铰接座13的插接槽133。
本实施例中的支撑腿12和上支杆14的数量均为四个，且上支杆14和支撑腿12均具有能够相套接且能够相对伸缩的杆件15，该折叠椅伸缩折叠后体积较小，减小包装尺寸；通过在折叠椅的中心设置上铰接座11和下铰接座13，分别将支撑腿12和上支杆14连接起来，多个支撑腿12和多个上支杆14交错设置，即每两个支撑腿12之间收容一个上支杆14，合理利用空间，折叠后体积较小；上铰接座11上设有连杆16，下铰接座13与连杆16可拆卸地连接，在展开状态时，连杆16连接于上铰接座11和下铰接座13之间，具有较好的结构稳定性；第一下铰接部和第二下铰接部采用高低错落的方式设置，靠背杆的倾斜角度较小(即较为接近竖直面)，从而能对使用者的背部进行较好的支撑；前撑杆的倾斜角度较大(即较 为接近水平面)，前撑杆和靠背杆之间的间距增大，提高了使用舒适性。
本实施例的折叠椅结构简单且成本较低，在展开状态时，多个支撑腿12的下端部相对展开，多个上支杆14的上端部相对展开，连杆16连接于上铰接座11和下铰接座13之间，折叠椅由展开状态转向折叠状态时，向上拉上铰接座11，支撑腿12和上支杆14会随之翻转(如图4所示)，接着收缩各个支撑腿12和各上支杆14的杆件15至图5所示的状态，折叠收纳后的体积较小。
实施例2
参照图6至图9所示，本实施例与实施例1的区别在于：上铰接座11和下铰接座13之间不通过任何杆件直接连接，其他基本同实施例1。参照图6至图9所示，上铰接座11的中部向下延伸，下铰接座13的中部向上延伸，上铰接座11和下铰接座13之间除了多个上支杆14和多个支撑腿12，无其它任何连接部件。当该折叠椅在如图8所示的展开状态时，上铰接座11和下铰接座13相互抵接，更具体地，上铰接座11和下铰接座13相互抵接；该折叠椅在如图9所示的在折叠状态时，上铰接座11和下铰接座13相分离。
上铰接座11的中部具有向下延伸的下延伸段，下延伸段上开设有插接槽。下铰接座13的中部具有向上延伸的上延伸段，上延伸段的上端部形成插接部。折叠椅展开时，上铰接座11和下铰接座13相互靠近，上延伸段的上端部逐渐插入到下延伸段的插接槽内；折叠椅折叠时，上铰接座11和下铰接座13相对远离，上延伸段的上端部逐渐脱离下延伸段的插接槽。上延伸段的高度、下延伸段的高度或二者的高度之和均小于上支杆14或支撑腿12收缩后的长度。
