Description

Technical Field

[0001] The invention belongs to the technical field of airborne airdrop, and in particular, is a control belt device suitable for a double paraglider. Background Art

[0002] The control belts of the Paratrooper-11 series are divided into a left control belt and a right control belt. The left and right control belts are further divided into two pieces, the front and rear. The bottom ends of the front and rear control belts are sewn together through a combined wrapping belt with a width of 25mm. The front detachable rope buckle of the left control belt is connected to the front group of parachute ropes on the left half of the canopy, and the rear detachable rope buckle is connected to the front and rear parachute ropes on the left half of the canopy. The front detachable rope buckle of the right control belt is connected to the front group of parachute ropes on the right half of the canopy, and the rear detachable rope buckle is connected to the front and rear parachute ropes on the right half of the canopy. The length of the control belt is 550±15mm, which can ensure that the parachutist can grasp the control circle more conveniently. A ring is sewn at the end of the control belt, which can be connected to the large ring on the parachute bag strap system. The structure of the control belt can be seen in Figure 1 .

[0003] The hook belt of the Paratrooper-11 series control belt is designed at the back, which can fit with the velvet belt on the back of the control ring at the end of the control rope. The hook-velvet structure is used to fix the control ring on the control belt before opening the parachute. After opening the parachute, the parachutist directly holds the control ring, tears the hook-velvet joint surface, and operates the wing parachute. This structure has a big disadvantage: the bonding strength of the structure with hook belt and velvet belt decreases significantly after repeated use. During the opening process, the control ring is easily detached from the control belt due to the impact of the dynamic load of the opening parachute, and it is very easy to get entangled with the parachute rope after flying off. There have been parachuting injuries caused by the control ring flying off and getting entangled with the parachute rope during the opening process. Summary of the invention

[0004] The purpose of the present invention is to provide a wing parachute control belt device suitable for two people, which is used to solve the problem that the control ring in the prior art is easy to fly off during the parachute opening process.

[0005] The technical solution for achieving the purpose of the present invention is: a control belt device suitable for a double wing parachute, including a front control belt, a rear control belt, a hook belt, a combined wrapping belt, a ring, two detachable rope buckles and a protective cloth; the front control belt is connected to the front group of parachute ropes through the detachable rope buckle, and the rear control belt is connected to the rear group of parachute ropes through the detachable rope buckle; the front control belt and the rear control belt pass through the ring at the end and are sewn and fixed by the combined wrapping belt, the ring is connected to the large ring on the parachute bag strap system, the hook belt is sewn to the middle position of the outer side of the rear control belt, and is bonded to the velvet belt on the control ring, so that the control ring can be fixed on the rear control belt; the protective cloth is sewn on the inner side of the rear control belt, and the position of the protective cloth coincides with the hook belt, and is respectively located on the inner and outer sides of the rear control belt.

[0006] Furthermore, a velvet tape is sewn on one end of the main protective cloth and a hook tape is sewn on the other end, and the velvet tape and the hook tape are respectively located on two sides of the main protective cloth; the length of the protective cloth and the relative positions of the hook tape and the velvet tape can make the hook tape and the velvet tape fit exactly after wrapping the operating ring.

[0007] Furthermore, the length of the control belt is 550±15 mm.

[0008] Furthermore, the length of the protective fabric is 130±5 mm.

[0009] Furthermore, the length of the velvet tape is 100±5 mm, and the width is 25 mm to 30 mm.

[0010] Furthermore, the hook tape has a length of 70±3 mm and a width of 25 mm to 30 mm.

[0011] Furthermore, a protective cloth is sewn opposite to the hook tape on the rear operating tape, and the velvet tape on the protective cloth is located on the outer surface of the rear operating tape during sewing; after the operating ring is bonded to the hook tape, the hook tape wraps the operating ring and rolls 360 degrees before bonding to the velvet tape.

[0012] Compared with the prior art, the present invention has the following significant advantages: the protective cloth is added, so that the control ring and the control belt are not only bonded by the hook-and-loop tape, but the outer protective cloth further enhances the wrapping ability, ensuring that the control ring and the control belt are tightly bonded and do not separate during the parachute opening process. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] Figure 1 This is a schematic diagram of the structure of the Paratrooper-11 series control belt.

[0014] Figure 2 It is a schematic diagram of the structural composition of the present invention.

[0015] Figure 3 It is a schematic diagram of the protective cloth structure of the present invention. DETAILED DESCRIPTION

[0016] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0017] The present invention makes structural improvements on the existing control belt and designs a protective device that can strengthen the bonding force between the control ring and the control belt. By adding a protective cloth to the control belt, after the control ring is bonded to the control belt, the protective cloth is used for secondary reinforcement to prevent the control ring from flying off prematurely.

[0018] The present invention designs a novel operating belt, wherein a piece of protective cloth is sewn opposite to the hook belt of the rear operating belt, the velvet belt on the protective cloth is located on the outer surface of the rear operating belt, after the operating ring is bonded to the rear operating belt through the hook velvet belt, the protective cloth wraps the operating ring and rolls it inwardly 360 degrees, and then bonds to the velvet belt on the protective cloth.

[0019] The present invention proposes a high-safety control belt suitable for tandem skydiving, which is mainly composed of a front control belt 1, a rear control belt 2, a hook belt 3, a combined wrapping belt 4, a ring 5, a detachable rope buckle 6 (two) and a protective cloth 7. Figure 2 .

[0020] When in use, the front control belt 1 is connected to the front group of umbrella ropes through the detachable rope buckle 6, and the rear control belt 2 is connected to the rear group of umbrella ropes through the detachable rope buckle 6. The front control belt 1 and the rear control belt 2 pass through the ring 5 at the end and are sewn and fixed by the combined wrapping belt 4. The ring 5 is used to connect with the large ring on the umbrella bag harness system to transmit the canopy aerodynamic force exerted on the control belt to the umbrella bag harness system. The length of the control belt is 550±15mm, which can ensure that a parachutist with a height of 1.6m to 1.95m can quickly grasp the control ring upwards. The hook belt 3 is used to bond with the velvet belt on the control ring (the control ring is another component and does not belong to the composition of the present invention) to ensure that the control ring can be fixed on the rear control belt 2.

[0021] The innovation of the present invention is to sew a protective cloth 7 on the rear piece operating belt 2. The position of the protective cloth 7 is directly opposite to the hook belt 3 on the rear piece operating belt 2. The structure of the protective cloth 7 is shown in FIG. Figure 3 . A velvet tape 10 with a width of 25mm to 30mm is sewn on one end of the protective cloth 7, and the length of the velvet tape is 100±5mm. A hook tape 8 with a width of 25mm to 30mm is sewn on the other end of the protective cloth 7, and the length of the hook tape is 70±3mm. The velvet tape 10 and the hook tape 8 are respectively located on both sides of the protective cloth 7. The length of the protective cloth is 130±5mm, which can ensure that the hook tape 8 and the velvet tape 10 fit exactly after wrapping the control ring. When wrapping the parachute, after the control ring is bonded to the hook tape 3, the protective cloth 7 is wrapped around the outer surface of the control ring to bond the hook tape 8 to the velvet tape 10. After the canopy is full, the parachutist manually pulls open the bonding surface between the hook tape 8 and the velvet tape 10, grasps the control ring and starts to operate the canopy.

[0022] The invention has been tested and verified, and has been put into use. The product has good performance and can meet various index requirements.
