Description

Easy to deploy parachute and umbrella bag

The present invention relates to a parachute and an umbrella bag, and more particularly to a parachute and an umbrella bag that are easy to deploy.

The parachute is mainly made of breathable fabric and can be stored in a storage bag or box. When in use, the parachute's canopy must be able to be quickly unfolded in order to truly generate air resistance and allow people or objects to decelerate stably and safely.

Most of the current parachutes are folded in advance and stored in a backpack. When a user parachutes, he or she decides the appropriate time to open the umbrella, and then manually opens the buckle of the backpack, so that the umbrella cover can be released from the backpack and then dropped. Wind action to open the umbrella. However, when the umbrella cover is released from the back bag, it may still not be able to be unfolded smoothly (such as being entangled, improperly folded, etc.), resulting in occasional fall accidents.

In order to improve the safety of the parachute, there are currently cases such as the "automatically safe start parachute" of the Republic of China Invention Patent Publication No. I363024, which is mainly an automatic safe start parachute that can determine the appropriate opening time and automatically and immediately initiate the opening operation. . The principle is based on the acceleration of the rotating director and the Global Positioning System unit to measure the height change and rotation of the landing body during the descent process, determine the timing of automatic start, and then control the magnetron unit to open the bag.

The above-mentioned case I363024 is mainly for judging the timing of the parachute opening and automatic parachute opening, but it is still not possible to ensure that the parachute is opened from the backpack.

Another example is the "escape low-level parachute with a circular ring-shaped six-fold elastic stretcher" in the Chinese invention patent application No. CN 107161348. It is mainly located under the umbrella surface inside the parachute mouth, and is equipped with a circular ring-shaped six-fold elastic stretcher. When the device is folded, the elastic automatic stretcher can be folded, so that the elastic automatic stretcher can accumulate elasticity. When the umbrella is released, the parachute can be assisted by the elastic force of the elastic automatic spreader.

In the aforementioned case CN 107161348, although the parachute can be assisted by the elasticity of the elastic automatic spreader, the elastic automatic spreader still needs to overcome a certain compressive force before it can be deployed to release the elasticity. This situation becomes more pronounced when the size is larger), so it is not suitable to use only an elastic automatic spreader to assist in expanding the parachute.

Secondly, since the size of the elastic automatic spreader needs to correspond to the size of the parachute that is dropped, there are difficulties in the production and folding of the product.

Therefore, in order to make the parachute easier to deploy, the inventor proposed an easy-to-deploy parachute including: a parachute body and at least one auxiliary parachute opening assembly. The parachute body includes an umbrella cover, which defines a wind receiving space and an air inlet, and the air inlet communicates with the wind receiving space. The at least one auxiliary parachute assembly is connected to the parachute body. The at least one auxiliary parachute assembly includes an elastic ring and an air guide. The elastic ring is deformably located in the wind receiving space and corresponds to the air inlet. The air piece is connected to the elastic ring; when the elastic ring is compressed and deformed in a stored state, the elastic ring accumulates an elastic force; when the elastic ring releases the elastic force and is in a stretched state, the elastic ring assists in supporting the expansion ring The umbrella cover assists the introduction of airflow into the wind receiving space by the air guide.

The present invention may also be an umbrella bag, including: a storage bag and a parachute. The parachute includes a parachute body and at least one auxiliary parachute assembly. The parachute body includes an umbrella cover that defines a wind receiving space and an air inlet. The air inlet communicates with the wind receiving space and the at least one auxiliary opening umbrella. The assembly is connected to the parachute body. The at least one auxiliary parachute assembly includes an elastic ring and an air guide. The elastic ring is deformably located in the wind receiving space and corresponds to the air inlet. The air guide is connected to the elastic ring. ; When the elastic ring is compressed and deformed into a storage state, the parachute is stored in the storage bag, and the elastic ring accumulates an elastic force; when the parachute is released from the storage bag, the elastic ring releases the elastic force and becomes a The opened state is to assist in supporting the opening of the umbrella cover and to guide the airflow into the wind-receiving space through the air guide.

Further, the air guide is a pipe, one end of the pipe is connected to a peripheral edge of the elastic ring, and the other end of the pipe extends in a direction away from the elastic ring. The pipe defines a wind guide channel, and the air guide The wind passage communicates with the wind receiving space and the air inlet.

Further, one end of the elastic ring is connected to the umbrella cover, and a pull rope is connected between the other end of the elastic ring and an umbrella rope of the parachute body to limit the angle of the elastic ring with respect to the umbrella cover.

Further, the number of the auxiliary umbrella opening assembly is one pair.

Further, the number of the auxiliary umbrella opening components is plural, and the auxiliary umbrella opening components are equally spaced in the umbrella cover.

Further, the storage state includes a first storage state and a second storage state; in the first storage state, the elastic ring is twisted; in the second storage state, the elastic ring is aligned to make the elasticity The diameter of the ring becomes smaller.

Further, the elastic ring is round.

Further, the material of the elastic ring is spring steel, shape memory alloy, fiber composite material, or flexible plastic.

Further, the diameter width T1 of the elastic ring is smaller than the diameter width T2 of the air inlet, and 0.5T2> T1.

According to the above technical features, the following effects can be achieved:

1. The elastic cover can be used to help open the umbrella cover to make the parachute easy to unfold, reducing the probability of failure or inaccurate opening.

2. The elastic ring can be deformed and compressed, so the space can be reduced to improve the convenience of storage.

3. In addition to the elastic ring to help open the umbrella cover, the airflow can also be introduced through the wind guide to make the parachute easier to deploy.

4. With equidistant ring distribution or paired auxiliary umbrella opening components, it can help to evenly and stably open the umbrella cover.

5. The air guide can be a soft material cloth tube, so it can avoid hindering the folding of the elastic ring.

6. Use small size elastic ring to reduce the difficulty of manufacturing and folding.

Based on the above technical features, the main effects of the parachute and umbrella bag that can be easily deployed in the present invention will be clearly shown in the following embodiments.
