Description

靠背式折叠椅的支撑架 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 l l a，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 llbo 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 lib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)
与实施例 1不同的是： 本例还设有水平向的扶手 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。
