在本发明的描述中，需要说明的是，除非另有明确的规定和限定，术语“安装”、“相连”、“连接”应做广义理解，例如，可以是固定连接，也可以是可拆卸连接，或一体地连接；可以是直接相连，也可以通过中间媒介间接相连，可以是两个元件内部的连通。对于本领域的普通技术人员而言，可以具体情况理解上述术语在本发明中的具体含义。
实施例1
请参阅图1与图2，本实施方式涉及一种捆式折叠椅架，该折叠椅架至少包括成对的靠背杆1、成对的座杆2、成对的扶手杆3、成对的前脚杆5与成对的后脚杆6，向上抬起扶手杆3，折叠椅架收折后呈捆式折叠椅。
基于前述的折叠椅，本实施例对前脚杆5和后脚杆6的连接结构进行改进，每个前脚杆5从前到后向上倾斜延伸，每个后脚杆6从前到后向下倾斜延伸，每个后脚杆设有枢座10，所述枢座10与前脚杆5铰接且其铰接点A 11偏离后脚杆6，以使得前脚杆5和后脚杆6能够以平行并拢的方式收折。如此，借由枢座的设计，后脚杆6能够支撑前脚杆5，当前脚杆5和后脚杆6收拢折叠后，二者能够平行并拢，解决了现有的前脚杆5与后脚杆6收拢后存在角度的技术问题，使得折叠椅收折后的体积显著降低。
在一些实施例中，所述后脚杆6顶部连接枢座10，所述枢座10具有自后脚杆6顶端倾斜向下延伸的铰接部102，所述前脚杆5与铰接部102铰接。具体地，所述铰接部102形成倾斜向下延伸且向上开口的支撑槽，所述前脚杆5具有抵压在支撑槽内的撑开状态以及脱离支撑槽支撑的收合状态。
可选地，所述的枢座10整体呈倒V型设计，一斜侧101与后脚杆固定连接，另一斜侧构成铰接部102，铰接部102形成开口支撑槽供前脚杆支撑其中且其间设有铰接点A11供前脚杆5转动连接其中以实现转动收折。
为了进一步降低包装体积，本实施方式提供的每个前支撑杆7第一端与对应的扶手杆3铰接，第二端与对应的前脚杆上设置的第一滑座51铰接，所述的前支撑杆7上设置第二滑座12，对应该前支撑杆的座杆设置有连接座13，所述第二滑座12与连接座13铰接连接，所述前脚杆5设有第一限位部27，所述的前支撑杆7设有第二限位部26，所述的第一限位部27和第二限位部26分别设置在第一滑座51与第二滑座12的下侧以限制滑座的滑动行程，如此，所述的第一限位部27和第二限位部26能够限制第一滑座51与第二滑座12在折叠椅展开过程程度，以使其保持在作为椅子的状态；另一方面，向上抬起扶手杆3后，第二滑座12与连接座13滑动带动前支撑杆和座杆收折，借由第二滑座与连接座，前支撑杆和座杆能够平行并拢，解决了现有的前支撑杆和座杆之间收折后存在角度的技术问题。
在一些优选实施方式中，所述第二滑座与连接座的铰接点B 15相对于前支撑杆和座杆的轴线偏心设置，在折叠椅架的展开状态下，第二滑座 12与连接座 13的铰接点B 15位于座杆下侧，同时该铰接点B 15还位于支撑杆前，如此，前脚杆5和后脚杆6能够尽可能地与椅架的前支撑杆7和座杆2并拢，降低包装椅的径向尺寸。
在进一步的优选实施例中，所述的第二滑座 12与连接座 13之间形成朝向前脚杆开口的收容槽123供前脚杆收容其中，如此，与后脚杆6平行并拢的前脚杆5能够藏设在该收容槽123内，请参阅图4，收折后，侧面的收折宽度仅受到靠背杆、后脚杆以及前支撑杆的限制，而不受到前脚杆、座杆的限制，径向包装尺寸显著降低。

在本实施例中，每个座杆2中间侧通过连接座a 18与前脚杆铰接，且前脚杆5与连接座a 18的铰接点C相较于座杆偏心设置，如此，座杆与前脚杆、后脚杆收折后能够达到平行并拢。
可选地，所述折叠椅架还包括前交叉连杆9与后交叉连杆8，所述前交叉连杆9连接在前脚杆5与座杆2之间，后交叉连杆8连接在后脚杆6与靠背杆1之间，所述的前交叉连杆与后交叉连杆包括交叉连接的第一连杆与第二连杆，如此，提高整个椅架的支撑强度。
所述的第二滑座12与连接座13、第一滑座与连接座a、第三滑座与第四滑座均为塑料件。
收拢时，靠背杆第三滑座16往上滑动，后脚杆第四滑座17往下滑动，前支撑杆的滑座12和前脚杆的第一滑座51往上滑动；在保证使用体验的前提下，通过结构上的设计和优化，最大程度的减小收拢包装体积，降低运费成本 。
实施例2
请参阅图5，本实施例与实施例1的结构基本相同，区别在于每个靠背杆1与对应的后脚杆6通过翻转件40铰接，该翻转件40一端与靠背杆1的底端铰接，另一端与后脚杆6的中间铰接，如此，请参阅图6与图7，收拢时，靠背杆1上的第三滑座16往上滑动，翻转件40翻转驱使靠背杆1朝向后脚杆6靠拢，前支撑杆7的滑座12和前脚杆5的第一滑座51往上滑动，最终实现捆式收拢。
在一些示例中，所述的翻转件40包括第一连接片与第二连接片，每个靠背杆1分别通过第一连接片与第二连接片与对应的后脚杆6铰接，该靠背杆1的底部的至少部分位于第一连接片与第二连接片之间，如此，在折叠椅架的展开状态下，靠背杆的底部能够与后脚杆抵接，结构稳定，有利于结构紧凑。
在本说明书的描述中，参考术语“实施例”、“示例”等的描述意指结合该实施例或示例描述的具体特征、结构、材料或者特点包含于本发明的至少一个实施例或示例中。在本说明书中，对上述术语的示意性表述不一定指的是相同的实施例或示例。而且，描述的具体特征、结构、材料或者特点可以在任何的一个或多个实施例或示例中以合适的方式结合。
