Multi-layer escape umbrella

Abstract

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.

Description

Technical Field

[0001] The invention belongs to the field of high-altitude escape equipment, and in particular relates to a multi-layer escape umbrella. Background Art

[0002] When disasters such as fires and earthquakes occur, people will escape through stairs, elevators, and descent ropes, but they may not be able to find an escape opportunity due to the fire and smoke; airbags or lifts are only effective for lower floors. Parachutes have certain conditions for opening and cannot be used in general building escapes.

[0003] The single-layer high-altitude escape parachutes designed today cannot use the same size of umbrella cloth as the parachute due to environmental space limitations, so the air resistance generated during descent is not enough to support the safe landing of an adult. In addition, the air resistance acting on the single-layer umbrella surface can easily damage the umbrella cloth or ribs, causing accidents. Some other designs combine umbrellas, parachutes, and balloons to increase air resistance, but the structure is not compact. Due to environmental space limitations, the number of combined combinations generally does not exceed 3, and the air resistance generated during descent is still not enough to support the safe landing of an adult. Summary of the invention

[0004] In order to overcome the above-mentioned shortcomings of the existing escape umbrella, the present invention adopts a multi-layer umbrella cloth assembly to share an umbrella pole, so that the multi-layer umbrella cloth assembly is distributed at intervals along the umbrella pole. Such a compact structural design can increase the descent resistance with multi-layer umbrella cloth, and the multi-layer umbrella cloth assembly jointly bears the air resistance and is more resistant to wind damage.

[0005] In order to increase the air flow into the upper umbrella cloth, the area of ​​the umbrella cloth increases layer by layer starting from the bottom layer, and the area of ​​the top umbrella cloth is the largest. Therefore, the upper umbrella cloth has an extra edge part than the adjacent lower umbrella cloth, which can make air flow into the upper umbrella cloth from the edge. The larger the extra edge of the upper umbrella cloth than the adjacent lower umbrella cloth, the larger the umbrella cloth spacing, the more air flows into the upper umbrella cloth from the edge, and the greater the air resistance of the upper umbrella cloth. Under the condition of not exceeding the size of the environmental space, in order to increase the overall air resistance, it is necessary to increase the number of umbrella cloth layers, the area of ​​each umbrella cloth layer, and the spacing between umbrella cloths as much as possible.

[0006] The top layer of umbrella cloth needs to have lower air permeability, so as to increase the descent resistance of this layer of umbrella cloth. However, the layers of umbrella cloth below it need to maintain a certain air resistance and supply a certain amount of air to the layers of umbrella cloth above. Therefore, the fabrics of the bottom layers of umbrella cloth have higher air permeability than the top layer of umbrella cloth, and small holes or gaps for air permeability are left on the umbrella cloth. The more and larger the small holes or gaps in the bottom layer of umbrella cloth, the more air will flow into the upper layer of umbrella cloth, and the greater the air resistance of the upper layer of umbrella cloth, while the air resistance of the lower layer of umbrella cloth will be smaller. When actually designing small holes or gaps, it is necessary to balance the air resistance of the lower and upper layers of umbrella cloth, so that the air resistance is generally evenly distributed in each layer of umbrella cloth.

[0007] The technical solution adopted by the present invention is: a multi-layer escape umbrella, comprising an umbrella handle (1) and an umbrella pole (2), characterized in that a multi-layer umbrella cloth assembly is distributed at intervals along the umbrella pole, the umbrella cloth assembly comprises a base ring (3), a spring piece (4), a rotating rod (5), an umbrella rib (6), and an umbrella cloth (7), the area of ​​the umbrella cloth increases layer by layer from bottom to top, a plurality of umbrella ribs are installed on the lower surface of the umbrella cloth, a movable base ring is provided on the umbrella pole, and the base ring and the umbrella ribs are movably connected via a rotating rod, and except for the top layer of umbrella cloth, the remaining layers of umbrella cloth have small holes (8) or gaps (9) for ventilation.

[0008] Furthermore, the number of layers of the umbrella cloth assembly is 5 to 10 layers.

[0009] Furthermore, in the umbrella cloth (7), the top layer of the umbrella cloth has lower air permeability than the remaining layers of the umbrella cloth.

[0010] Furthermore, when the umbrella cloth (7) is opened, it follows the shape of an umbrella cloth, a parachute canopy, or a glider canopy.

[0011] Furthermore, the shape of the umbrella cloth (7) when expanded is hemispherical or frustum-shaped.

[0012] Furthermore, the length of the umbrella pole (2) is retractable.

[0013] Furthermore, the umbrella pole (2) is provided with a spring sheet (4) for limiting the position of the base ring.

[0014] Furthermore, the surface of the umbrella handle (1) has an anti-slip texture.

[0015] The invention has the following beneficial effects: the multi-layer umbrella cloth assembly is arranged on the same umbrella pole, the compact structure can increase the descent resistance with the multi-layer umbrella cloth, and the multi-layer umbrella cloth assembly jointly bears the air resistance and is more resistant to wind damage; the upper umbrella cloth has an extra edge portion than the lower umbrella cloth, so that air can flow from the edge into the upper umbrella cloth, and the small holes or gaps in the lower umbrella cloth can make air flow from the lower umbrella cloth into the upper umbrella cloth; the pre-opening solves the problem that the traditional parachute cannot be fully opened due to insufficient height, and has the characteristics of convenient use and simple operation.

[0019] In order to make the objectives, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings.

[0020] Example 1

[0021] like Figure 1 As shown, it is a structural schematic diagram of Example 1 of the present invention, including an umbrella handle 1, an umbrella pole 2, and 5 layers of umbrella cloth components are distributed along the umbrella pole at intervals of 0.3 meters. The umbrella cloth components include a base ring 3, a spring piece 4, a rotating rod 5, an umbrella rib 6, and an umbrella cloth 7. The area of ​​the umbrella cloth increases layer by layer from bottom to top. A plurality of umbrella ribs are installed on the lower surface of the umbrella cloth. A movable base ring and a spring piece for limiting the base ring are provided on the umbrella pole, and the base ring and the umbrella rib are movably connected by a rotating rod. Except for the top layer of umbrella cloth, the remaining layers of umbrella cloth have small holes 8 for ventilation.

[0022] The umbrella pole can be extended and retracted. When in use, the length of the umbrella pole after extension is about 1.5 meters. There is a non-slip texture on the surface of the umbrella handle. The umbrella pole, rotating pole and ribs are all made of high-strength steel to prevent breakage and rust. The top layer of umbrella cloth has low air permeability, and parachute materials such as nylon can be used; the remaining layers of umbrella cloth have higher air permeability than the top layer of umbrella cloth. Commonly used umbrella cloth is used, and there are multiple small holes distributed in a ring around the umbrella pole to increase air permeability. When the umbrella cloth is opened, it imitates the umbrella cloth and is hemispherical. The radius of the umbrella cloth gradually increases by 0.1 meters from bottom to top, from 0.8 meters at the bottom to 1.2 meters at the top.

[0023] This embodiment can be used by a person weighing about 50 kg to escape. When in use, after stretching the umbrella pole, 5 layers of umbrella cloth are pre-opened like operating an umbrella, and then the person can jump out of the building. Since the umbrella cloth has been pre-opened, when descending, the airflow will flow from the extra edge of the umbrella cloth and the small holes on the lower umbrella cloth into the space of the upper layers of umbrella cloth, slowing down the descent speed, and effectively solving the problems of insufficient air resistance, tearing of umbrella cloth, and broken umbrella ribs.

[0024] Example 2

[0025] like Figure 2 As shown, it is a schematic diagram of the structure of Example 2 of the present invention, comprising an umbrella handle 1, an umbrella pole 2, and 10 layers of umbrella cloth components are distributed along the umbrella pole at intervals of 0.2 meters. The umbrella cloth components include a base ring 3, a spring piece 4, a rotating rod 5, an umbrella rib 6, and an umbrella cloth 7. The area of ​​the umbrella cloth increases layer by layer from bottom to top. A plurality of umbrella ribs are installed on the lower surface of the umbrella cloth. A movable base ring and a spring piece for limiting the base ring are provided on the umbrella pole, and the base ring and the umbrella rib are movably connected by a rotating rod. Except for the top layer of umbrella cloth, the remaining layers of umbrella cloth have air-permeable gaps 9.

[0026] The pole can be extended and retracted, and when in use, the pole is stretched to a length of about 2 meters. The surface of the handle has a non-slip texture. The pole, rotating pole, and ribs are all made of high-strength steel to prevent breakage and rust. The top layer of umbrella cloth has low air permeability and uses parachute materials such as nylon; the remaining layers of umbrella cloth have higher air permeability than the top layer of umbrella cloth, using commonly used umbrella cloth, and there are multiple gaps distributed around the pole to increase air permeability. When the umbrella cloth is opened, it is shaped like the umbrella cloth and is hemispherical. The radius of the umbrella cloth increases by 0.1 meters from bottom to top, from 0.7 meters at the bottom to 1.6 meters at the top.

[0027] This embodiment can be used by a person weighing about 100 kg to escape. When in use, after stretching the umbrella pole, 10 layers of umbrella cloth are pre-opened like operating an umbrella, and then the person can jump out of the building. Since the umbrella cloth has been pre-opened, when descending, the airflow will flow from the extra edge of the upper umbrella cloth and the gap on the lower umbrella cloth into the space of the upper layers of umbrella cloth, slowing down the descent speed, and effectively solving the problems of insufficient air resistance, tearing of umbrella cloth, and broken umbrella ribs.

[0028] The above-described embodiments are only preferred embodiments for fully illustrating the present invention, and the protection scope of the present invention is not limited thereto. Equivalent substitutions or changes made by those skilled in the art based on the present invention are within the protection scope of the present invention. The protection scope of the present invention shall be subject to the claims.
