The umbrella 20 is prevented from being twisted and deformed by excessive atmospheric pressure.
The through column 22 reinforces the ability of the spherical umbrella 20 to withstand wind resistance, and opens an air injection hole 23 around the bottom opening 212 of the spherical umbrella 20. The air injection hole 23 penetrates the spherical umbrella 20 and the bottom clamp 222 and is provided with a plug portion 24 that seals the air injection hole 23. A plurality of connecting portions 25 are fixed to the bottom of the spherical umbrella 20 so as to surround the central axis a1, and the connecting portions 25 are nylon ropes having high tension and are connected to the descending object 60 at the other end.

The guide ring 30 surrounds the central axis a 1 and is fixed around the spherical umbrella 20, and includes a ring 31 and a skirt portion 32 extending below the spherical umbrella 20, and four airflow guides are provided on the bottom end surface of the ring 31. The recesses 311 are formed, and each of the airflow guide recesses 311 is formed by projecting an airflow duct 33 above the spherical umbrella 20. The airflow duct 33 is a structure made of a flexible material and has a conical shape that gradually contracts upward. A guide hole 331 is formed at the end of the airflow duct 33 to form four tanks 34, and an auxiliary is provided at the center. An axis a2 is provided.
The upper and lower sides of the tank 34 have a cylindrical shape with an opening 341, and a bottom annular pedestal 346 is formed projecting from the center of the tank 34, a cylindrical space 347 is formed around the bottom annular pedestal 346, and the airflow duct 33 is formed into a cylinder.

A fixing ring 36 is molded on the top of the guide ring 30, and the fixing ring 36 is fixed around the spherical umbrella 20 so as to surround the central axis a <b> 1. The fixing ring 36 reinforces the ability of the spherical umbrella 20 to withstand wind resistance, and prevents the spherical umbrella 20 from being twisted and deformed by excessive atmospheric pressure. Four auxiliary holes 361 are opened on the fixing ring 36, and each tank 34 is drilled and positioned in each auxiliary hole 361.

  The auxiliary umbrellas 40 each have a plurality of high-strength nylon ropes as fixed portions 41 and fixed to the moving end 351 of the sliding column 35, and each fixed portion 41 is equally fixed on the moving end 351.

FIG. 1 shows a state in which each auxiliary umbrella 40 is fully opened when the parachute of the present invention is lowered. When the user descends from a high place and falls downward due to gravity, the air collides with the bottom of the spherical umbrella 20 and the guide ring 30 of the present invention, thereby generating an air buoyancy opposite to the descending direction and decelerating. Has the effect of descending.
Further, as shown in FIG. 2, the special guide ring 30 in the present invention has an effect of collecting an air flow. In the present invention, when the loaded descending object 60 is lowered, the gas is placed under the guide ring 30. Since it is collected by the section 32, flows into the airflow duct 33 through the airflow guide recess 311 and is finally blown out of the tank 34, the auxiliary umbrella 40 in the tank 34 is in any form at the time of starting. However, it opens smoothly by the air flow blown out from the tank 34, the buoyancy of the air is further increased, the descent speed of the user is reduced, and the effect of safely descending is achieved.

The guide ring 30 has a rotationally symmetric structure with the central axis a1 as the axis, and even if the auxiliary umbrella 40 is fixed to the moving end 351, it still maintains rotational symmetry with the central axis a1 as the axis, and each tank Since 34 and the auxiliary umbrella 40 also have a rotationally symmetric structure with the auxiliary axis a2 as an axis, the present invention has an overall stable balance effect when descending (see FIGS. 1 to 3).
In addition, since the storage space 345 is provided in the tank 34 of the present invention, the auxiliary umbrella 40 can be folded when not in use and stored in the storage space 345 of the tank 34. Effectively reduce the volume to be stored. In addition, since the present invention does not require any operation in terms of use, the object of the descending object 60 to smoothly descend even if it is a lifeless article can be achieved using the present invention.

  When the auxiliary umbrella 40 is opened, the moving end 351 fixed to the fixing portion 41 of the auxiliary umbrella 40 moves upward. At this time, the operating end 352 pushes open the elastic member 344, and the clamp 342 is connected to the airflow duct 33. Since the gas passing through the airflow duct 33 is reduced, the buoyancy of the parachute of the present invention is increased and the descending speed is reduced (see FIGS. 2 and 3).

FIG. 4 is an inclined external view of the second embodiment of the present invention. In this example, only a slight difference is seen in the appearance of the parachute, and the number of auxiliary umbrellas 40B is three.
A feature of the present invention is the effect of collecting the airflow by the guide ring 30B, which is smoothly opened by the airflow blown by the auxiliary umbrella 40B, so that the guide ring 30B has a rotationally symmetric structure about the central axis a1. Since the present invention has a stable balance effect when descending, the creative object of the present invention can be achieved in another embodiment as shown in the figure.
