[0001] This invention relates to the field of emergency escape equipment technology, specifically to a levitation umbrella. Background Technology

[0002] When a fire breaks out inside a high-rise building, people will use fire escape stairs, fire elevators, or fire ladders to escape and receive emergency treatment. However, in the following situations: 1. Fire escape stairs are blocked by smoke, preventing people from escaping through them; 2. Fire elevators are shut down due to the fire; 3. When it is difficult to rescue people on a fire-prone floor, or when people's lives are in danger, people inside the building will not be able to carry out emergency rescue and escape smoothly. Summary of the Invention

[0003] In view of this, the purpose of the present invention is to provide a levitation umbrella that enables emergency escape in the event of an emergency in a high-rise building.

[0004] The levitation umbrella provided by this invention adopts the following technical solution:

[0005] A levitation umbrella includes a pole, multiple ribs evenly distributed at the top of the pole, and a canopy mounted on the ribs. The ribs are rotatable on the pole. Multiple sets of wing assemblies for providing upward lift when the canopy rotates are evenly distributed along the edge of the canopy. Each set of wing assemblies is connected to the ribs in a one-to-one correspondence. Each wing assembly includes a flat-convex wing on the upper side of the canopy and a tilting wing on the lower side of the canopy. The higher end of the flat-convex wing corresponds to the lower end of the tilting wing.

[0006] Furthermore, a rotating rod is rotatably provided at the top of the umbrella pole, the umbrella ribs are evenly distributed on the rotating rod, and a drive motor for driving the rotating rod to rotate is provided on the umbrella pole.

[0007] Furthermore, the umbrella pole is provided with a mounting shell for mounting a drive motor. The rotating rod is inserted into the umbrella pole and extends downward close to the mounting shell. The drive motor is vertically arranged in the mounting shell, and the output end of the drive motor extends upward and is coaxially and fixedly connected to the rotating rod.

[0008] Furthermore, the umbrella rib includes a fixed rod fixedly mounted on a rotating rod and a sliding rod slidably mounted on the fixed rod. The end of the sliding rod is connected to the umbrella wing assembly, and the sliding rod is driven to slide on the fixed rod to retract and extend the umbrella wing assembly.

[0009] Furthermore, the fixed rod is provided with a locking element for fixing the slide rod when it is retracted.

[0010] Furthermore, the projection surfaces of the plano-convex wing and the tilting wing on the umbrella surface are both arranged in a fan shape.

[0018] The following specific examples illustrate the implementation of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention.

[0019] The following is in conjunction with the appendix Figure 1-3 The present invention will be described in further detail below.

[0020] This invention discloses a levitation umbrella. (Refer to...) Figures 1-3The levitation umbrella includes a hollow umbrella pole 1, multiple umbrella ribs 2 evenly distributed at the top of the umbrella pole 1, and an umbrella canopy 3 mounted on the umbrella ribs 2. In this embodiment, there are six umbrella ribs 2. To ensure the strength of the levitation umbrella, the umbrella ribs 2 are made of rigid materials, such as steel or other metals. The umbrella canopy 3 is made of parachute fabric, which is denser than ordinary umbrella canopy 2 and can withstand greater gravity. The umbrella ribs 2 can be driven to rotate on the umbrella pole 1. Multiple sets of wing assemblies 4 are evenly distributed along the edge of the umbrella canopy 3 to provide upward lift when the umbrella canopy 3 rotates. In this embodiment, there are six sets of wing assemblies 4, and each set of wing assemblies 4 is connected to one umbrella rib 2. 4 includes a flat-convex wing 41 disposed on the upper side of the canopy 3 and a tilting wing 42 disposed on the lower side of the canopy 3. The cross-section of the tilting wing 42 is triangular. The higher end of the flat-convex wing 41 corresponds to the lower end of the tilting wing 42. In order to reduce the overall weight of the levitation parachute, both the flat-convex wing 41 and the tilting wing 42 are hollow in this embodiment. When in use, the canopy 3 is driven to rotate, with the higher side of the flat-convex wing 41 and the lower side of the tilting wing 42 in front. During the rotation, the wing assembly 4 can provide upward lift to the canopy 3, reduce the speed at which people fall downward, minimize the damage to people, and increase the chances of survival in emergency situations.

[0021] A rotating rod 11 is rotatably mounted on the top of the umbrella pole 1. The rotating rod 11 is inserted into the top of the umbrella pole 1, and the umbrella ribs 2 are evenly distributed on the rotating rod 11. The umbrella pole 1 is equipped with a drive motor 12 for driving the rotating rod 11 to rotate. In use, the drive motor 12 is started to rotate the rotating rod 11, which drives the umbrella surface 3 to rotate, so that the umbrella wing assembly 4 provides lift to the umbrella surface 3. At the same time, different speeds of the drive motor 12, the size of the umbrella surface 3, and the tilt angle of the umbrella wing assembly 4 can be selected as needed to obtain different lift. Users can significantly reduce their movement speed when jumping from a high place to a low place to meet safety requirements. In this embodiment, the rotating rod 11 is mounted on the umbrella pole 1 through a bearing, which can reduce the friction between the rotating rod 11 and the umbrella pole 1 when rotating, making the rotation of the rotating rod 11 smoother.

[0022] To protect the drive motor 12, a mounting shell 13 is provided on the umbrella pole 1 for mounting the drive motor 12. One side of the mounting shell 13 can be opened to facilitate continued inspection of the drive motor 12 and battery replacement. The start switch and speed adjustment switch of the drive motor 12 are located on the side wall of the mounting shell 13 for easy control of the drive motor 12. The rotating rod 11 is inserted into the umbrella pole 11 and extends downward close to the mounting shell 13. The drive motor 12 is vertically mounted in the mounting shell 13, and the output end of the drive motor 12 extends upward and is coaxially fixedly connected to the rotating rod 11. By mounting the drive motor 12 in the mounting shell 13, the drive motor 12 can be protected and prevented from being damaged by prolonged exposure to air.

[0023] To facilitate the storage or carrying of the paraglider, the paraglider rib 2 includes a fixed rod 21 fixedly mounted on the rotating rod 11 and a sliding rod 22 slidably mounted on the fixed rod 21. The fixed rod 21 has a track inside for the sliding rod 21 to slide. The end of the sliding rod 22 is connected to the wing assembly 4. The sliding rod 22 is driven to slide on the fixed rod 21 to retract and extend the wing assembly 4. In this embodiment, the projection surfaces of the plano-convex wing 41 and the tilting wing 42 on the paraglider surface 3 are both fan-shaped. When in use, the wing assembly 4 is pushed outward to move the sliding rod 22 outward, so that the paraglider surface 3 is fully opened and the sliding rod 22 is fixed. When retracting, the sliding rod 22 is released, the wing assembly 4 is pushed inward to retract the wing assembly 4, and the sliding rod 22 is fixed. This can minimize the area of ​​the paraglider surface 3, making it convenient to store and carry the paraglider.

[0024] To facilitate the fixing of the slide rod 22, the fixing rod 21 is provided with a locking member 23 for fixing the slide rod 22 when it is retracted. In this embodiment, the locking member 23 is a bolt. In other embodiments, the locking member 23 can also be a buckle, spring pin, etc. The locking member 23 is set at the end of the fixing rod 21 near the umbrella wing assembly 4 by means of threads. The slide rod 22 has a threaded hole on the side wall near the umbrella rod 1. When the umbrella surface 3 is retracted, the locking member 23 is rotated so that the locking member 23 is threaded into the threaded hole of the slide rod 22 to fix the slide rod 22. When in use, the locking member 23 is loosened and the umbrella wing assembly 4 is pushed outward. The centrifugal force experienced by the umbrella wing assembly 4 during the rotation of the umbrella surface 3 will prevent the umbrella wing assembly 4 from being retracted.

[0025] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
