Description

折叠装置
技术领域
本发明涉及一种折叠装置， 特别涉及一种通过自身折叠缩小占用空间、 便 于携带的折叠装置。 背景技术
市场上现有的舞台、 工作台铺垫板往往都是整块的， 这样既浪费材料， 又 不方便收纳， 有些可折叠的也只是实现对折， 不能进一步折小， 占用大量的收 纳空间；
当自然灾害导致桥梁、 道路中断或者断裂时， 抢险队往往需要先搭接整块 的梁柱或横梁接通道路， 整块的梁柱或横梁占用空间大， 携带很不方便， 影响 抢险效率和速度；
现有的折叠梯一般釆用缩短长度的方法， 将很长的梯子折叠成较短的长度， 如"人"字梯或者多次折叠梯，这些经过一次或多次折叠的梯子仍然占用较大的空 间（无法盘曲折叠)， 特别是这些折叠梯用于消防或者攀登时， 消防人员或攀登员 携带时仍不方便， 从而影响救火时机或者攀登效率。 发明内容
本发明的目的是提供一种折叠装置。
根据本发明的一个方面， 提供了一种折叠装置， 包括两个以上折合体、 至 少一个连接体和两个以上连接轴。
折合体的截面呈 U型， 折合体设有至少一个孔， 连接体的两端分别插入在 两个折合体的 u型框内， 与折合体铰接连接。
连接轴的一端固定在折合体的孔中， 连接轴的另一端固定在另一个折叠装 置的折合体的孔中。
本发明连接体的两端分别与折合体铰接连接， 多个折合体和多个连接体可 以间隔重复铰接连接， 同时， 多个折叠装置之间可以通过连接轴相互连接； 当 折合体和连接体延伸呈直线状态时， 利用连接件和折合体之间的相互拗力转变 成折叠装置的承托力， 承托重物， 当折叠装置盘曲收纳时， 可以很大程度地较 少折叠装置的占用空间， 折叠装置既能盘曲收纳， 减少占用空间， 携带方便， 又能延伸使用， 并演变成多种形态的工具， 如梯子、 工作平台、 桥梁或道路断 裂时的搭接梁。
在一些实施方式中， 连接体的两端可以设有凸起， 连接体与折合体呈直线 状态时， 折合体 U型框内部可以设有与凸起匹配的的凹部。 由此， 连接体与折 合体呈直线状态时， 折合体 U型框内部的凹部扣接在连接体的凸起上， 可以确 保折合体和连接体不易发生相对转动。
在一些实施方式中， 折合体的数量可以为 N， 连接体的数量可以为 M， N 为 3以上的自然数， M为 2以上的自然数， 折合体和连接体依次间隔铰接连接。 由此， 可以加长折叠装置呈直线状态时的长度， 提高折叠装置在抢险、 救灾、 登山时的利用率。
在一些实施方式中， 多个折叠装置可以并行排布。 由此， 多个通过连接轴 连接的折叠装置并行排布可以演变成多种形态的工具如舞台、 工作平台、 救生 平台（下置气嚢)使用。
在一些实施方式中， 连接体与折合体连接的两端可以呈圓弧状。 由此， 可 以确保连接体和折合体相互转动顺畅。 附图说明：
