Description

靠背式折叠椅的支撑架
所属技术领域
本实用新型属一种带靠背的折叠椅支撑架。
背景技术
现有靠背式折叠椅的支撑架的主要结构是(参见图1)：设有斜向的两根前腿杆(1)和两根后腿杆(2)，前腿杆上部向斜后上方延伸形成靠背支撑杆，椅面支撑杆(3)中部与前腿杆铰链连接，后端与后腿杆铰链连接，连接片(4)两端分别与椅面支撑杆上方的前腿杆和后腿杆铰链连接，支撑架撑开时，后腿杆上端顶在前腿杆中部。这种折叠椅支撑架的不足之处是：撑开使用时，若在椅面后部施力，很容易使椅面前部向上翘起，整个支撑架失去重心跌倒，而且连接片部位很容易夹伤人体。
发明内容
本实用新型要解决的技术问题是提供一种能稳定牢固地处于撑开状态、不易失去重心翻倒、不易夹伤人体、使用安全的靠背式折叠椅的支撑架。
解决上述问题的技术方案是(参见实施例图)：本实用新型设有两根前腿杆(1)、两根后腿杆(2)，两椅面支撑杆(3)，支撑架后部设有靠背杆(8)，其特征在于：所述的后腿杆(2)上端与套在前腿杆(1)上的滑套(5)铰链连接，滑套上部的前腿杆上设有滑套限位部件(6)，椅面支撑杆(3)中部与前腿杆位于滑套(5)下方的杆体部位铰链连接，后端与后腿杆(2)中部铰链连接，在两侧连为一体的前、后腿杆、椅面支撑杆、靠背杆之间设有横向支撑部件(10，7，14，15)。
本支撑架折叠时，滑套(5)沿前腿杆下滑(见图2)，椅面支撑杆(3)前部向后上方折起，撑开时，滑套(5)沿前腿杆上滑至顶在限位部件(6)上。
本实用新型撑开状态稳定，在椅面前部施力或后部施力均不会发生椅面上翻失去重心的情况，不易夹伤人体，使用安全。

具体实施方案
实施例1(图2～图5)
本例设有两根前腿杆1和两根后腿杆2，后腿杆2上端与套在前腿杆1上的滑套5铰链连接，滑套上部的前腿杆上设有滑套限位部件6，两椅面支撑杆3中部分别与两侧前腿杆位于滑套5下方的杆体部位铰链连接，后端与后腿杆2中部铰链连接，前、后腿杆与椅面支撑杆形成A字形连接结构。
上面所述的椅面支撑杆“中部”或后腿杆“中部”是指位于杆体上与两端拉开一定距离的部位。
靠背杆8是由前腿杆1向斜后上方的延伸部分组成，两侧连为一体的前、后腿杆、椅面支撑杆、靠背杆之间设置的横向支撑部件10是由两根中间铰链连接形成的X形支架组成，X形支架下部两端分别与两前腿杆1铰链连接，上部两端分别与两侧的椅面支撑杆3铰链连接，横向支撑部件7是由两根中间铰链连接形成的X形支架组成，X形支架下部两端分别与两后腿杆2下部铰链连接，上部两端分别与两侧靠背杆8铰链连接，从而使两前腿杆之间和两后腿杆之间可向中间折叠靠拢，本例横向支撑部件10上部两端从其与椅面支撑杆3铰链点处向上弯曲延伸，形成扶手9。
在靠近限位部件6下边缘的前腿杆部位与滑套5之间设有滑套锁紧装置，本例滑套锁紧装置的结构是：在后腿杆体上设有弹性触头11a，滑套5内壁上设有能使弹性触头嵌入的凹孔，滑套5外壁上设有能按下弹性触头的按钮11b。当滑套5滑到限位部件6处时，弹性触头弹性嵌入滑套内壁的凹孔内，将滑套与前腿杆锁紧，从而滑套既不能向上滑动也不能向下滑动，使撑开的支撑架更加稳定。按下按钮11b使弹性触头从滑套凹孔脱出，滑套5即与前腿杆解锁，可向下滑动，使支撑架能折叠收拢。
本例撑开后可装上软质椅面(见图4)，不用时整个支撑架可向中心轴折叠收拢(见图5)。
利用本实施例结构还可以将两个以上的支撑架并排连为一体，相连处共用一套连为一体的前、后腿杆和椅面支撑杆，折叠时均可向中心靠拢。
实施例2(图6～图9)
本例设有水平向的扶手12，扶手12后端与套在前腿杆上1上的滑套5铰链连接，扶手12与椅面支撑杆3之间设有与二者铰链连接的扶手支撑杆13。
实施例3(图10～图11)
本例在两椅面支撑杆3之间装有硬质椅面14，该硬质椅面既可作椅面，还兼有在两侧连为一体的前、后腿杆、椅面支撑杆之间起横向支撑部件的作用，本例在两靠背杆8之间设有横向支撑部件15。
本例折叠时椅面支撑杆3前部向后上方折起。与实施例1不同的是两前腿杆及两后腿杆之间不能靠拢。
以上所述，仅是本实用新型的较佳实施例，并非对本实用新型作任何形式上的限制，凡是依据本实用新型的技术实质对以上实施例所作的任何简单修改、等同变化与修饰，均仍属本实用新型技术方案的保护范围。
