Abstract

The invention discloses an articulated four-ring strap. A chest loop and a crotch loop are added to the traditional non-articulated strap, and a metal ring is added to the crotch to connect the main strap, the leg strap and the horizontal back strap together. Metal rings are added to the chest to connect the upper main strap, chest strap and lower main strap. The present invention solves the problems that the traditional strap does not fit the body completely and consumes a lot of physical strength, and also takes into account the post-maintenance of the strap.

Description

Articulated four-ring harness

technical field

The invention relates to the technical field of paratroopers, in particular to an articulated four-ring harness.

Background technique

The main function of the harness system is to connect the skydiver to the parachute system. Designed around safety, comfort and practicability, focusing on the following four aspects: 1. Evenly distribute the load while ensuring strength; 2. Comfort on the ground and during skydiving; 3. Coordination of various parachute linkage mechanisms Use; 4. Arrangement of connection rings and binding points of various tasks necessary equipment.

At present, the commonly used practical solution is a two-loop strap, and a crotch loop is added to the traditional strap. However, when the standard strap is stressed, the connecting part between the back of the umbrella bag and the sides of the main strap and the leg strap is twisted and deformed. Stress is concentrated at the bend and the suture may break.

SUMMARY OF THE INVENTION

The purpose of the present invention is to provide an articulated four-ring strap.

The technical solution to achieve the purpose of the present invention is: an articulated four-ring strap, adding a chest loop and a crotch loop to the traditional non-articulating strap, adding a metal ring to the crotch, and connecting the main sleeve strap, leg strap and back horizontally. The straps are joined together and metal loops are added to the chest to connect the upper main strap, chest strap and lower main strap.

The articulated four-ring strap is composed of an upper main cover belt, a lower main cover belt, a leg belt, a crotch ring, a chest ring, and a chest belt;

The upper main strap is connected to the upper part of the chest ring, and the lower main strap is connected to the part from the chest ring to the crotch ring; the chest ring is respectively connected to the chest straps on both sides; the crotch ring is respectively connected to the leg straps on both sides.

Compared with the prior art, the present invention has significant advantages: (1) It provides a more reasonable force distribution without local stress concentration, because each component of the strap can be rotated and naturally flattened during assembly and hanging. This design gives the skydiver a wide range of adjustment both in the air and on the ground, and increases the fit and comfort of the harness, which is stronger under high shock loads. (2) It fits the human body better than traditional straps.

Description of drawings

FIG. 1 is a schematic structural diagram of an articulated four-ring strap of the present invention.

Detailed ways

The present invention adds a chest loop 5 and a crotch loop 4 to the traditional non-articulated strap.

Add metal loops to the crotch to connect the main strap, leg straps and back cross straps together. The three kinds of webbing are naturally flat and not twisted. Improved human comfort for greater comfort and safety around the upper thighs and better leg movement during landings.

Add metal rings to the chest. Attach the upper main strap, chest strap and lower main strap. Allows skydivers to perform a full range of motion in the air and on the ground. It also reduces the movement of the umbrella bag on the back.

The present invention will be further described below with reference to the accompanying drawings.

The present invention is mainly composed of an upper main sleeve belt 1 , a lower main sleeve belt 2 , a leg belt 3 , a crotch ring 4 , a chest ring 5 , and a chest belt 6 .

The main strap is the webbing that holds the entire harness together. It needs to withstand all loads from parachute opening to landing. The length of the main belt is fixed, and the main belt can be divided into an upper main belt 1 and a lower main belt 2.

The upper main belt 1 is the upper part of the chest ring 5 (the junction of the chest belt), which includes a suspender belt, a lining belt, a combined bag belt and a diagonal strap. The upper main belt should be placed with a stabilizer umbrella handle, an emergency umbrella handle, and a backup umbrella handle. The handle of the stabilizing umbrella is on the right side, and the handle of the emergency release umbrella and the pull ring of the backup umbrella are on the left side. When the pull ring of the backup umbrella handle is pulled, the handle of the emergency umbrella release can be pulled off in linkage, so as to prevent the main umbrella from accidentally inflating during the emergency opening and backup.

The lower main cuff 2 is the part from the chest loop 5 (the junction of the chest strap) to the crotch loop 4 .

The chest strap 6 prevents the skydiver from slipping out of the front of the harness and is used to adjust the tightness of the harness. The chest strap is less loaded because most of the load on the main harness is transferred from the steering straps to the leg straps. A lower strength webbing can be used.

In addition to the chest strap 6, the leg straps 3 are the remaining 2 adjustment points for the harness. It can be part of the main strap or can be attached to the crotch ring 4 alone. Because the scheme is a four-ring strap, it is selected to be connected to the crotch ring 4 separately, and the material is a webbing with a slightly lower strength than the main strap. Due to the large legroom position, quick release hook adjustment is optional. At the same time, in order to prevent wear and sliding, vinylon belts are added to the adjustment part.

The oblique strap directly bears the opening overload of the stabilizer, so choose to extend from the main strap. The position is between the umbrella bag and the back pad, all the way to the waistband. The function of the crossbody strap is to hold the body in place and sew the entire strap together. If there is no diagonal strap, the umbrella bag will directly bear the dynamic load of opening the umbrella, resulting in damage to the umbrella bag.

To sum up, the present invention improves the comfort of the human body and reduces the maintenance cost by adding a crotch loop and a chest loop to the traditional strap. And it has been used in the production of scientific research samples, and through 24 aerial tests, the test proves that this technology can improve the comfort of skydivers.
