A parachute pack

Abstract

This invention relates to a parachute pack for a parachute compartment. The compartment contains a support column, a circumference, and multiple tension straps. The circumference is barrel-shaped with a circular hole at its bottom and an opening at its top, through which the support column passes sequentially. Multiple tension straps are evenly arranged circumferentially along the circumference, with their bottoms fixedly connected to the circumference. The tops of the tension straps move towards or away from the opening at the top of the circumference, and can move to a first position and a second position. When the tops of the tension straps move to the first position, they form a cover structure with a central opening to close the top of the circumference. When the tops of the tension straps move to the second position, they are spaced apart to open the opening at the top of the circumference. This invention solves the problem that existing parachute packs are difficult to adapt to irregularly shaped parachute compartments with support columns inside the installation cavity.

Description

Technical Field

[0001] This invention relates to the field of parachute technology, and more particularly to a parachute pack. Background Technology

[0002] As is well known, in parachute systems, the parachute compartment is mostly of a regular shape, such as a cylindrical cavity, to facilitate the placement of the parachute pack inside.

[0003] When used in certain special environments, it is necessary to set up corresponding irregularly shaped parachute compartments. For example, such as Figure 1 The irregularly shaped parachute compartment shown is cylindrical in shape, and its internal mounting cavity contains coaxially arranged columns. These columns are used to support and mount cameras, detection instruments, weapons, etc. In this case, the columns will affect the parachute pack's deployment procedure.

[0004] Existing parachute packs are difficult to adapt to irregularly shaped parachute compartments with uprights inside the cavity. Summary of the Invention

[0005] In view of this, it is necessary to provide a parachute pack to solve the problem that existing parachute packs are difficult to adapt to irregularly shaped parachute compartments with uprights inside the installation cavity.

[0006] This invention provides a parachute pack for a parachute compartment. The compartment contains a support column, a circumference, and multiple tension straps. The circumference is a barrel-shaped structure with a circular hole at its bottom and an opening at its top, through which the support column passes sequentially. The tension straps are evenly distributed circumferentially along the circumference of the circumference. The bottoms of the tension straps are fixedly connected to the circumference. The tops of the tension straps can move towards or away from the opening at the top of the circumference, and can move to a first position and a second position. When the tops of the tension straps move to the first position, they form a cover structure with a central opening to close the top of the circumference. When the tops of the tension straps move to the second position, they are spaced apart to open the opening at the top of the circumference.

[0007] Furthermore, there is partial overlap between two adjacent traction bands.

[0008] Furthermore, it also includes an annular elastic element, which is sequentially connected to the tops of the plurality of traction belts so that the tops of the plurality of traction belts are in a first position.

[0009] Furthermore, the tension belt is an arc-shaped belt, and both ends of the tension belt are fixedly connected to the circumference. The annular elastic element is disposed through the gap between the tension belt and the circumference.

[0010] Furthermore, the bottom of the circumference is bonded to the inner bottom wall of the parachute compartment.

[0011] Furthermore, it also includes a circumferential belt, which is fitted onto the outer wall of the circumference and located at the bottom of the tension belt.

[0012] Furthermore, there are multiple circumferential bands, which are sequentially arranged along the length of the circumference to form a reinforcing ring.

[0013] Furthermore, there are multiple reinforcing rings, which are arranged sequentially from the inside to the outside of the enclosure.

[0014] Furthermore, it also includes a reinforcing band, which is sleeved on the outer wall of the circumference, and a fixed gap is formed between the reinforcing band and the circumference for fixing the plurality of tension bands.

[0015] Furthermore, the reinforcing strip is located at the bottom of the traction strip.

[0016] Compared with existing technologies, the current design features a barrel-shaped structure with a circular hole at the bottom and an opening at the top. This allows the support column to pass through the hole and the opening sequentially, enabling the parachute pack to be installed within the irregularly shaped canopy, effectively avoiding the need for a support column. Simultaneously, multiple traction straps are evenly distributed along the circumference of the current design. The bottom of each strap is fixedly connected to the current design, and the tops of the straps move towards or away from the opening at the top of the current design, and can move to a first position and a second position. When the tops of the straps reach the first position, they form a cover structure with a central opening, sealing the top of the current design, allowing the parachute to be placed within the current design. When the tops of the straps reach the second position, they are spaced apart, opening the top of the current design, allowing the parachute to detach from the current design.

[0021] Preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, which form part of this application and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not intended to limit the scope of the present invention.

[0022] like Figure 1-2 As shown, the present invention provides a parachute pack for a parachute compartment 100. The compartment 100 houses a support column 110, which includes a circumference 200 and multiple pulling straps 300. The circumference 200 has a barrel-shaped structure, with a circular hole at its bottom and an opening at its top, allowing the support column 110 to pass through the hole and the opening sequentially. Multiple pulling straps 300 are evenly arranged circumferentially along the circumference of the circumference 200, and their bottoms are fixedly connected to the circumference 200. The top of the pull belt 300 moves along the direction of the opening at the top of the circumference 200, and can move to a first position and a second position. When the top of the pull belt 300 moves to the first position, the top of the pull belt 300 forms a cover structure 210 with a central opening to close the top of the circumference 200. When the top of the pull belt 300 moves to the second position, the tops of the pull belt 300 are spaced apart to open the opening at the top of the circumference 200.

[0023] In implementation, the circumference 200 has a barrel-shaped structure with a circular hole at the bottom and an opening at the top, allowing the support column 110 to pass through the hole and opening sequentially. This enables the parachute pack to be installed in the irregularly shaped parachute compartment 100, effectively avoiding the support column 110. Simultaneously, multiple tension straps 300 are evenly arranged circumferentially along the circumference of the circumference 200. The bottoms of the tension straps 300 are fixedly connected to the circumference 200, and the tops of the tension straps 300 are positioned near or away from the openings at the top of the circumference 200. The system can move to a first position and a second position. When the top of the multiple pulling straps 300 moves to the first position, the top of the multiple pulling straps 300 forms a cover structure 210 with a central opening to close the top of the enclosure 200, so that the parachute can be placed in the enclosure 200. When the top of the multiple pulling straps 300 moves to the second position, the tops of the multiple pulling straps 300 are spaced apart to open the opening at the top of the enclosure 200, at which time the parachute can detach from the enclosure 200.

[0024] In actual use, the parachute is placed between the span 200 and the support column 110. The parachute lines pass through the inner bottom wall of the parachute compartment 100 and are connected to an external load (such as an aircraft). The top of the parachute is connected to a tow parachute, which is located outside the parachute pack and the parachute compartment 100. Before use, the tops of the multiple tow straps 300 are in the first position, and the parachute is built into the parachute pack. When in use, by releasing the tow parachute, the tow parachute is subjected to an external force collision, which generates a pulling force on the parachute pack and the parachute. First, the parachute pack and the parachute are pulled out of the parachute compartment 100 simultaneously. Under the relative force between the parachute pack and the parachute, the tops of the multiple tow straps 300 move to the second position, and the parachute detaches from the parachute pack, thus completing the parachute opening process.

[0025] In this embodiment, the circumference 200 is the outer packaging structure of the parachute pack. Specifically, the circumference 200 is a barrel-shaped structure with a round hole at the bottom and an opening at the top, through which the upright 110 passes in sequence.

[0026] The width 200 is made of textile material, and the size of the width 200 is determined according to the size of the umbrella bag.

[0027] In one embodiment, the bottom of the circumference 200 is bonded to the inner bottom wall of the parachute compartment 100. Of course, in other embodiments, the bottom of the circumference 200 can also adopt other forms of structure to achieve a detachable connection with the inner bottom wall of the parachute compartment 100. It should be noted that the above connection structure should not affect the function of the circumference 200 detaching from the parachute compartment 100.

[0028] In this embodiment, the multiple tension straps 300 can open or close the opening at the top of the circumference 200 under the action of external force. Specifically, the multiple tension straps 300 are evenly arranged circumferentially along the circumference of the circumference 200. The bottom of the multiple tension straps 300 is fixedly connected to the circumference 200. The tops of the multiple tension straps 300 can move in a direction close to or away from the opening at the top of the circumference 200, and can move to a first position and a second position. When the tops of the multiple tension straps 300 move to the first position, the tops of the multiple tension straps 300 form a cover structure 210 with a central opening to close the top of the circumference 200. When the tops of the multiple tension straps 300 move to the second position, the tops of the multiple tension straps 300 are spaced apart to open the opening at the top of the circumference 200.

[0029] In one embodiment, there is partial overlap between two adjacent traction belts 300.

[0030] In order to keep the traction belt 300 in the first position for a long time to enclose the parachute therein, in one embodiment, an annular elastic member is also included. The annular elastic member is sequentially connected to the top of the plurality of traction belts 300 so that the top of the plurality of traction belts 300 is in the first position.

[0031] The annular elastic element can be made of rubber band. Under the elastic force of the rubber band, the tops of multiple traction straps 300 are drawn towards the middle of the opening at the top of the circumference 200 to achieve the function of wrapping the parachute. During the parachute opening process, the traction parachute pulls the parachute away from the parachute pack. At this time, the force applied by the traction parachute to the multiple traction straps 300 causes the rubber band to break, and the multiple traction straps 300 move to the second position, thereby realizing the parachute opening process.

[0032] In one embodiment, the traction belt 300 is an arc-shaped belt, with both ends of the traction belt 300 fixedly connected to the circumference 200, and an annular elastic element passing through the gap between the traction belt 300 and the circumference 200.

[0033] To strengthen and support the parachute, this embodiment also includes a circumferential belt 400, which is fitted onto the outer wall of the circumference 200 and located at the bottom of the traction belt 300.

[0034] In one embodiment, there are multiple circumferential bands 400, which are sequentially arranged along the length of the circumference 200 to form a reinforcing ring.

[0035] In another embodiment, there are multiple reinforcing rings, which are arranged sequentially from the inside to the outside of the circumference 200.

[0036] To improve the connection strength between the tension belt 300 and the width 200, this embodiment also includes a reinforcing belt 500, which is sleeved on the outer wall of the width 200, forming a fixing gap between the reinforcing belt 500 and the width 200 for fixing the multiple tension belts 300. The reinforcing belt 500 is located at the bottom of the tension belt 300.

[0037] Among them, the reinforcing strip 500 can be made of multi-layered textile or metal materials, which plays an important role in shaping the umbrella.

[0038] Compared with existing technologies: the circumference 200 has a barrel-shaped structure with a circular hole at the bottom and an opening at the top, allowing the support column 110 to pass through the hole and opening sequentially. This enables the parachute pack to be installed in the irregularly shaped parachute compartment 100, effectively avoiding the support column 110. Simultaneously, multiple tension straps 300 are evenly arranged circumferentially along the circumference of the circumference 200. The bottoms of the tension straps 300 are fixedly connected to the circumference 200, and the tops of the tension straps 300 are positioned near or away from the openings at the top of the circumference 200. The multiple pulling straps 300 can move in the direction of movement and can be moved to a first position and a second position. When the top of the multiple pulling straps 300 moves to the first position, the top of the multiple pulling straps 300 forms a cover structure 210 with a central opening to close the top of the enclosure 200, so that the parachute can be placed in the enclosure 200. When the top of the multiple pulling straps 300 moves to the second position, the tops of the multiple pulling straps 300 are spaced apart to open the opening at the top of the enclosure 200, at which time the parachute can detach from the enclosure 200.

[0039] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in the present invention should be included within the scope of protection of the present invention.
