Description

折叠椅结构 技术领域
本发明是关于一种结构简单，展收简易的折叠椅结构，属于日常生活领域。
背景技术
折叠椅具有易折收且便携的特点，其不仅适用于户外及临时场所的使用，亦是家居必备的应急使用物品。传统的折叠椅多是由折叠支架支撑布面构成，构成的折叠支架是由多根支杆配合多个模块构成，因此折收体积较大，无法较佳的体现轻便易携、易收藏的特点。
发明内容
本发明的目的是提供一种结构简单、折收体积更紧凑，更易携带与收藏的折叠椅结构。
为实现上述目的，本发明的解决方案是：
一种折叠椅结构，其中：包括一椅座支架、一椅脚支架及活动连接椅座支架与椅脚支架的连接支撑架；椅座支架上配合有椅座布面；所述椅座支架包括两前支杆及两后靠杆；该椅脚支架包括至少四根支脚杆；该连接支撑架包括两组连接架及一横向连接两连接架的连接杆，各组连接架分别由两V型管对扣通过二者的支脚相互固定在一起，而连接杆的两端是分别伸置于两连接架中两V型管对扣形成的空间内固定，各V型管的两支脚供椅座支架与椅脚支架的各杆件插置配合，插置在同一个V型管的两杆件之间设置弹性绳。
所述椅座支架与椅脚支架各杆件的配合端部形成缩颈以插置于各V型管的支脚端口中。
所述各V型管的支脚端口形成缩颈而插置于椅座支架与椅脚支架的各杆件中。
所述椅座支架的后靠杆是由多节杆件构成。
所述椅座支架与椅脚支架的各杆件采用多节杆件构成。
采用上述方案后，本发明是利用两个相互对扣的V型管形成连接架，再通过一连接杆连接两连接架形成折叠椅的连接支撑架，各V型管支脚的端口形成配合椅座支架与椅脚支架的各杆件的插孔，如此构成一折叠椅，而通过穿设于各V型管中的弹性绳实现折叠椅各杆件与连接支撑架的折收，实现结构简单，制作成本低且折收体积更紧凑，更易携带与收藏的功效。
另外，此处连接杆的设置不仅易于调整折叠椅的宽度，同时增加连接支撑架的支撑强度。
附图说明
图1是本发明折叠椅的展开示意图；
图2是本发明另一实施例折叠椅的展开动作图；
图3是本发明另一实施例折叠椅的展开示意图；
图4是本发明折叠椅的实施示意图。
具体实施方式
如图1至图4所示，本发明揭示了一种折叠椅结构，其包括一椅座支架1、一椅脚支架2及活动连接椅座支架1与椅脚支架2的连接支撑架3，椅座支架1上配合有椅座布面5。
所述连接支撑架3包括两组连接架31及一横向连接两连接架31的连接杆32，各组连接架31分别是由两V型管30对扣通过二者的支脚301相互固定在一起，而连接杆32的两端是分别伸置于两连接架31对扣的两V型管形成的空间内固定，此处各V型管之间，以及与连接杆32的固定是采用焊接的固定形式；而各V型管30的两支脚301的端口供椅座支架1与椅脚支架2的各杆件插置配合；插置在同一个V型管30的两杆件之间设置弹性绳4，即：该弹性绳4是穿过V型管30而连接两杆件。
所述椅座支架1包括至少两前支杆11及至少两后靠杆12，其中后靠杆12的长度是大于前支杆11的长度。
所述椅脚支架2包括至少四根支脚杆21。
配合图2所示，所述连接支撑架3各V型管30的支脚端口是形成了椅座支架1与椅脚支架2各杆件的插孔，当然，亦可将各V型管30的支脚端口形成缩颈而插置于椅座支架1与椅脚支架2的各杆件中。此实施例是将椅座支架1与椅脚支架2各杆件的配合端部形成缩颈10以插置于各V型管30的支脚端口中，如此保证杆件与连接支撑架3外观整体性更佳。V型管30的设置是便于弹性绳4的穿设。
组合时，连接支撑架3的各V型管30中穿设弹性绳4，弹性绳4的两端连接与各自V型管30配合的杆件，如此令椅座支架1、椅脚支架2与连接支撑架3构成折叠椅架。
当椅子使用时，只需将椅座支架1与椅脚支架2的各杆件插置于连接支撑架3各V型管30的各端口中即可；反之折收椅子时，只需将椅座支架1与椅脚支架2的各杆件从连接支撑架3各V型管30的各端口中拔出即可，由于受限于弹性绳4的作用，令各部件不至于脱离，并且可以实现最紧凑的收合，达到最小的收合体积，以方便收藏与携带。
再配合图3所示，椅座支架1的前支杆11与后靠杆12可由多节杆件构成，即各杆件的端部可形成缩颈以利于相互之间的套接，如此可进一步缩短杆件折收后的长度，令收合更加合理。使用时，松释对各杆件的束缚力，抖动各杆件，在弹性绳4的弹性力作用下，即可将椅架轻松展开。
上述由多节杆件构成的前支杆11或/和后靠杆12亦可通过连接杆实现配合，即各连接杆的一端固定于一杆件中，另一端与相邻的杆件为活动套接关系。
当然，椅脚支架2的各支脚杆21亦可采用多节杆件构成。
综上，本发明是利用两个相互对扣的V型管30形成连接架31，再通过一连接杆32连接两连接架31形成折叠椅的连接支撑架3，各V型管30的支脚301的端口形成配合椅座支架1与椅脚支架2的各杆件的插孔，如此构成一折叠椅，而通过穿设于各V型管30中的弹性绳4实现折叠椅各杆件与连接支撑架3的折收，实现结构简单，制作成本低且折收体积更紧凑，更易携带与收藏的功效。另外，此处连接杆32的设置不仅易于调整折叠椅的宽度，同时增加连接支撑架3的支撑强度。
