Pre-opening parachute

The present invention provides a pre-open parachute that is related to the structure of the parachute.

Parachute, a kind of landing gear that provides a safe descending from a height, and there are many types of parachutes. Among them, the projectiles and towed parachutes need to have sufficient height or space to match the airflow resistance or displacement kinetic energy when falling at high altitude. After a period of time, it can be determined to open. However, the high-rise buildings located on the street of the building do not have sufficient height and space, and there is an unusable dilemma; therefore, there is a balloon parachute 10 as shown in Figure 1, The air flow resistance cover 11 and the air flow resistance cover 11 are mainly connected by a plurality of first cables 13 , and one end of the first cables 13 is coupled to the air ball 12 . The other end is coupled to the circumference of the airflow resistance cover 11, and the other end is coupled to a carrier 15; Thereby, when the balloon parachute 10 is dropped from a high altitude, the inflatable ball 12 first provides the buoyancy of the inflation, and the airflow resistance cover 11 provides airflow resistance, thereby causing the balloon to land. The umbrella 10 can provide a descending effect; however, when the balloon parachute 10 is actually applied, the inflatable ball 12 must have an extremely large size to provide sufficient buoyancy, and if it is small in size, it cannot provide charging. The buoyancy of the foot; and even the diameter of the airflow resistance cover 11 is several times larger than the size of the inflatable ball 12, so that the inflation time is too long to be suitable for the emergency escape; and because the overall balloon parachute 10 is too large In large, there is a lack of mobility difficulties; in view of this, the inventors have devoted themselves to research and further conceived, and after a number of research and development trials, finally invented a pre-open parachute.

More than the other end diameter, the circumferential surface 52 is different from the end adjacent to the arc top surface 51, and a ring wing portion 54 is further combined. The extending direction of the ring portion 54 has an angle with respect to the central axis X. The ring wing portion 54 of the embodiment is an annular piece structure extending outwardly from the circumferential surface 52 and toward the double descending force balloon umbrella 20, and the ring portion 54 is made of a hard material having no deformability. The pre-opening umbrella 50 is coupled to the other end of the universal joint 30 through a plurality of second cables 60, and one end of the second cables 60 is coupled to the arc top surface 51 of the pre-opening umbrella 50, and the other end is Converging at the other end of the universal joint 30; and thereby allowing the pre-opening umbrella 50 to freely rotate relative to the universal joint 30; A carrier 70 is coupled to the pre-opening umbrella 50 through a plurality of third cables 80.

Since the material is made of a material, the air hood portion 21, the arc top surface 51, and the circumferential surface 52 can be naturally deformed and compressed and stored as shown in FIG. 4 when not in use, and in this state, due to the The wing portion 54 of the opening umbrella 50 is made of a hard material, so that the wing portion 54 of the pre-opening umbrella 50 can serve as a foundation for carrying and storing, forming a stable storage state; and in use, the pre-opening type of the present invention The parachute can be placed in a high place or on the top floor of the building, and then inflated by the air nozzle 212 of the air hood portion 21 of the double descending balloon umbrella 20, and the air is filled to fill the gas filling space 211 of the air hood portion 21, filling The gas density in the plenum 211 is less than the air density, preferably filled with helium gas in the plenum 211 of the plenum portion 21; after the plenum 211 of the hood portion 21 is filled with gas, the hood portion 21 The gas in the inflated space 211 generates buoyancy L compared to the air, because The double descending balloon parachute 20 rises due to the buoyancy L, and when the double descending balloon parachute 20 is raised, the double descending balloon parachute 20 interlocks the first cable 40, the universal joint 30, and the The second cable 60, and the second cable 60 further drives the pre-opening umbrella 50 to rise, and the pre-opening umbrella 50 is opened by the lifting of the double descending force balloon umbrella 20 to complete the opening. An open parachute can complete an open umbrella without a height drop or any kinetic energy displacement; and after the overall pre-open parachute completes the open umbrella, the pre-open parachute can only be moved to a position where it can be lowered. , the landing of the pre-open parachute can provide the purpose of slow landing, as shown in Figure 5; When the pre-opening parachute of the present invention is lowered from a high place, the gas in the inflated space 211 of the inflatable cover portion 21 of the double-decreasing balloon umbrella 20 continuously provides the buoyancy L, and at the same time, the gas enters the pre-opening umbrella 50. The second resistance generating space 53 and the first resistance generating space 22 of the double-decreasing balloon parachute 20 can simultaneously generate a disturbance reduction in the first resistance generating space 22 and the second resistance generating space 53 respectively. The first resistance D1 and the second resistance D2, the double slow-down balloon umbrella 20 provides two buoyancy forces of buoyancy L and first resistance D1, and the second resistance D2 of the pre-opening umbrella 50 makes the pre-opening type of the invention The parachute has three descending forces during operation, and the sum of the buoyancy L, the first resistance D1 and the second resistance D2 generated by the pre-opening parachute of the present invention is greater than the sum of the weight of the integral parachute and the weight of the load, In this way, the pre-opening parachute of the present invention can provide a total of three upward forces by the buoyancy L, the first resistance D1 and the second resistance D2 to balance the weight of the parachute and the weight of the loader (eg, a parachutist), and thereby generate Slow down effect, so It can reach a steady landing speed state in a very short time, slow down the user's rapid fall feeling of gravity acceleration when the parachute first falls, ease the user's fear, and can enhance the willingness to use; Yes, when the pre-opening parachute of the present invention descends from a height and the gas enters the first resistance generating space 22 and the second resistance generating space 53, respectively, it must pass through the first port portion 214 and the second made of a hard material, respectively. The port portion 521, the first port portion 214 and the second port portion 521 made of a hard material can avoid the shock and vibration that may occur in the soft material, and can effectively guide the airflow and the shunt through the arranged arc-guiding form.
