The invention discloses a multilayer escape umbrella which comprises an umbrella handle, an umbrella rod and multiple layers of umbrella cloth assemblies distributed along the umbrella rod at intervals, each umbrella cloth assembly comprises a base ring, an elastic piece, a rotating rod, umbrella ribs and umbrella cloth, the area of the umbrella cloth is increased layer by layer from bottom to top, and small breathable holes or gaps are formed in the other layers of umbrella cloth except the umbrella cloth on the top layer. The umbrella has the advantages that the multiple layers of umbrella cloth assemblies are arranged on the same umbrella rod, the descending resistance can be increased through the multiple layers of umbrella cloth due to the compact structure, the multiple layers of umbrella cloth assemblies jointly bear air resistance, and wind damage is better resisted; the upper-layer umbrella cloth is more than the lower-layer umbrella cloth in edge part, so that air can flow into the upper-layer umbrella cloth from the edge, and the small holes or gaps of the lower-layer umbrella cloth can enable the air to flow into the upper-layer umbrella cloth from the lower-layer umbrella cloth; the problem that a traditional parachute cannot be completely opened due to insufficient height is solved by pre-opening the parachute, and the parachute has the advantages of being convenient to use and easy to operate.

    本发明公开了一种多层逃生伞,包括伞柄、伞杆,沿着伞杆间隔分布有多层伞布组件,所述伞布组件包括基环、弹片、旋转杆、伞骨、伞布,所述伞布从下到上,面积逐层增加,除去顶层的伞布,其余各层伞布上有透气的小孔或者缝隙。本发明的有益效果是:多层伞布组件设置在同一伞杆上,紧凑的结构能用多层伞布增加下降阻力,而且多层伞布组件共同承担空气阻力,更抗风力破坏;上层伞布比下层伞布多出边缘部分,能使空气从边缘流入上层伞布,下层伞布的小孔或缝隙能使空气从下层伞布流入上层伞布;预先开伞解决传统降落伞因高度不够,无法完全开伞的问题,具有使用方便、操作简单的特点。
