Description

Application area

The invention relates to the field of underwater sports, namely to spearfishing, freediving, and serves to secure ballast weights in order to compensate for the positive buoyancy of an underwater swimmer when immersed in water.

State of the art

A well-known cargo belt is worn on the user's waist, consisting of a belt with a quick-release buckle and ballast weights fixed on it (http://www.omer.tetis.ru/ing/catalog.php?group=belts&item=belts).

The disadvantage of this object is:

- the mass of ballast weights is concentrated in the lumbar, which leads to its overload, fatigue and the risk of spinal diseases;

- there is no way to adjust the stability of the swimmer;

- does not provide reliable, without displacement, fixation on the body in various spatial positions.

Also known is an unloading cargo vest with pockets for accommodating ballast weights made of elastic material (http://www.omer.tetis.ru/ing/catalog.php?group=naccessory&item=gilet).

Its disadvantage is:

- used in conjunction with the cargo belt, and takes over its inherent disadvantages;

- emergency relief in emergency situations is difficult, as it is necessary to open 2-3 buckles.

The closest adopted for the prototype is the diver's Mk1 suspension system made of textile tape and consisting of chest, back, shoulder, waist and leg belts equipped with adjusting buckles and forming a combination of front and rear spatial power panels for fastening goods and accessories (http://www.divexglobal.com/index.asp? id = 2 & ref = 28 & ref2 = 290 & ref3 = 301 & con = 3211). Leg belts are designed for optimal distribution of the tape around the legs of the user and the formation of the supporting part, are two closed loops, wrapping the legs of the user at the level of the hips. The system is reset when the quick-release buckle attached to the waist belt is opened and after the legs are released from the loops of the leg belts.

This technical solution does not allow you to urgently reset it in emergency situations, which is one of the main safety requirements, because when the belt buckle is opened, the system is not completely reset, the user needs to further free his legs from the loops of the leg straps. In the case of installing quick-release buckles on the foot straps, the user needs to additionally spend time and effort searching and opening these buckles. In view of the above, the suspension systems have not found practical application in spearfishing and freediving.

For additional fixation of the cargo system on the body, a breaststroke (inguinal) belt with a buckle is more often used, but it does not exclude the displacement of ballast weights, in addition, it is inconvenient due to the pressure of the belt on the inguinal region and complicates emergency discharge, for example, the cargo vest of the underwater hunter RafSong v. 2 (http://apox.ru/content/view/854/76/). The presented cargo systems do not possess the necessary set of safety and operating qualities, such as: reliable cargo fixation on the body without displacement; the ability to adjust the stability of the swimmer, determined by the relative position of the centers of gravity and buoyancy; increase the load on the lumbar spine; emergency reset difficult it is necessary to open 2-4 buckles, which in the absence of visibility, limited air supply and time, various spatial positions of the body, in gloves that reduce sensitivity, are additional complicating immersion factors.

Technical result: the invention improves the safety of diving and performance, reduces the load on the lumbar spine, provides the ability to accurately adjust the stability and buoyancy of the swimmer, as well as reliable, without displacement, the fixation of the cargo panels on the body in various spatial positions and while maintaining its mobility ; provides emergency dumping of the cargo system.

The implementation of the invention

The claimed technical result is achieved due to the fact that the cargo system of the underwater swimmer, containing two cargo panels - back and chest, shoulder and leg belts equipped with locking devices, characterized in that each cargo panel is made in the form of a flexible assembly of individual cargoes or in the form flexible assembly from individual segments to which ballast weights are fixed, and has the ability to bend in different directions; each load is movably connected to the next load and has through holes made with the possibility of a tensioner passing through them, and the foot straps are made in the form of one closed loop, on the opposite sides of which support elements are installed. In addition, ballast weights are configured to be coupled by means of a flexible base, such as a rubber plate.

The implementation of the invention

The proposed cargo system of the underwater swimmer contains two cargo panels - the back and chest, shoulder and foot straps equipped with elements of locking devices, in which, unlike the prototype, each cargo panel is made in the form of a flexible assembly of individual cargoes or in the form of a flexible assembly of separate segments, to which ballast weights are fixed, and has the ability to bend in different directions. Each cargo is made with the possibility of movable connection of the next cargo, for example, by the type of articulation; and the adjacent sides of the cargo are configured to provide mutual bending, for example in the form of a beveled or rounded surface. In order to realize the bending of the cargo panel in the sagittal plane, through holes are made through the holes, made with the possibility of passing through them a tensioner, for example a steel cable, a certain type of tension which is realized by a tension device, such as a tension spring. A tension device configured to control the tension forces pulls the tensioner and causes the cargo panel to bend until it rests on the physiological bends of the body. Leg belts are used for reliable fixation of cargo panels on the body and are made in the form of a single closed loop, for example, of textile tape, on the opposite sides of which support elements are installed that perform the function of optimal distribution of the tape around the user's legs and the formation of the supporting part. The lower parts of the cargo panels are attached to the supporting elements. Shoulder straps are equipped with elements of locking devices, such as fastex buckles, for connecting to the upper parts of cargo panels. The fixing force of the cargo panels is widely adjustable individually by the user.

The invention is illustrated by drawings. The cargo system (figure 1) contains two cargo panels chest 1, back 2, shoulder 3 and 4 foot 4 belts equipped with elements of locking devices 5. Each cargo panel (figure 2) is made in the form of a flexible assembly of individual loads 6. Each the load 6 is made with the possibility of a movable connection 7 of the next load and has through holes 8; and the adjacent sides of the cargo are configured to provide mutual bending, for example in the form of a beveled surface. Tensioner 9 is passed through the cargo openings 8, attached at one end to the end load of the cargo panel 12, and at the other end to the tension device 10. The bending of the cargo panel (Fig. 3) is implemented as follows - the tension device 10 pulls the tensioner 9 and causes the cargo panel to bend to supporting it on the physiological bends of the body. Leg girths 4 (Fig. 4) are made in the form of one closed loop, on the opposite sides of which support elements 11 are installed, to which the lower parts of the cargo panels 1 and 2 are connected.

The cargo system of the underwater swimmer is used as follows (sequence of actions). The user connects through the locking devices 5 the components of the cargo system, while one shoulder strap 3 leaves open. Spends a foot in the ring formed by the connected components of the cargo system. It puts a closed shoulder strap 3 on the shoulder, while the cargo panels 1 and 2 are placed on the back and chest, and the loop of the foot straps 4 is placed in the perineum, while the supporting elements 11 are located in front, in the inguinal region and behind on the buttocks. Then, through the locking device 5 connects the second shoulder strap 3 to the chest cargo panel 1. Corrects the weight and location of the ballast weights by removing or adding them to the cargo panels in order to adjust buoyancy and stability. Regulates the size and fixing force of cargo panels, depending on its height and weight of ballast weights. The cargo system is ready for use. When the locking device 5 is opened on the shoulder straps 3, the cargo panels 1 and 2, under the action of gravity and elastic forces 5 of the tension device 10, open and release the user, while the foot straps 4 freely leave the perineum, without interfering with the emergency discharge of the cargo system, and do not require manipulation to release.

For a more reliable fixation, the cargo system can be equipped with a lap belt, and the side of the weights adjacent to the body has an anti-slip coating. For the operational control of stability and buoyancy, ballast weights can be made interchangeable in design and shape, but with different weights. Thus, the proposed invention improves the safety of scuba diving and performance due to the dispersion of the mass of ballast weights over the body and reduce the load on the lumbar spine; the ability to fine-tune swimmer's stability and buoyancy; reliable, without displacement, fixation of cargo panels on the body in various spatial positions and while maintaining its mobility; providing emergency dumping of the cargo system.
