Abstract

The insulating suit consists of separate elements with an annular connector between a jacket and trousers, and with sealing rings arranged between connecting rings of said connector. The connector is formed so as to bend around the chest with the upper part in front, and around the lower back or buttocks with the lower part. Gloves and/or footwear have connectors with respect to adjacent elements of the suit, in which connectors those parts of connecting rings that are spaced apart from the limbs of the body are inclined towards the person's body. The technical result consists in the production of a structurally simple, comfortable and operationally reliable insulating suit for safe working in complex conditions and in a hostile atmosphere for a person.

Description

Insulating suit

Technical field

The utility model relates to the life needs of a person and to perform various operations in difficult conditions or in

aggressive environment. The device can be used in protective clothing for flights, space, work and hunting under water, rescue operations in mines and at sea, or in difficult conditions when it is necessary to perform operations related to protection from heat or cold, toxic chemicals, gas, low or high blood pressure.

State of the art

There are many designs of insulating suits that are used in various fields of human activity. In the spacesuit “Krechet” of the Scientific Research Enterprise “Star” on the back there is a rectangular hatch for astronauts to penetrate inside, which is hermetically closed with a satchel with life support equipment. With good insulation and a rigid body, it has considerable weight and does not allow to penetrate into the suit alone.

In the spacesuit “Apollo” (1 96g.), A zipper closes the entrance, passes from the neck down along the spine and then through the perineum to the lower abdomen. But gas and water protection zippers are not suitable for kinks, do not have a full guarantee against disconnection and are not designed to withstand high pressure.

There are various directions and locations of zippers on diving suits: horizontal on the chest (“Dry diving suit” KR 20120010247), from the left shoulder to the hip joint (Chinese patent CN 202 138523), in front of the chin to the groin (Romanian patent RO 126474 A2). And further many others. They all have a significant flaw - these costumes are hard to put on. You have to moisten the body or rub it with cream to penetrate the suit and bend it many times. All this is due to the fact that for the normal functioning of the zippers must be slightly stretched or straightened to avoid their excesses and, accordingly, the diver’s suit cannot be

free. This is not the only reason for the density when hugging the body with the material of the suit, it still has to “breathe”. In addition, all zippers have a sealed start and end: ring zippers have not yet been created. Therefore, a suit with a zipper connector cannot be divided into two parts, as in ordinary household clothes, into a jacket and trousers. Between them there will certainly be a fabric remaining between the beginning and the end of the zipper, and also the beginning of the zipper fastening the jacket and trousers, which excludes the use of an elastic fabric flap stretching in this area to facilitate putting on the suit.

The separation of the insulating suit into a jacket and trousers is claimed in the Ukrainian patent for the invention “Lifeguard and miner suit”, UA 883 1 1. In this case, the connection of the upper and lower parts of the suit should be ensured by transverse lightning. This is hardly possible for the above reason. Most likely, the jacket and trousers will be pulled together when superimposed on each other using a belt, as described in the description of this patent. A significant drawback is the sealing of the hood over the edge of the protective helmet. The helmet is always in operation, it may have a back Temperature and nadkoly. Reliability seal when such a compound is not ensured. costume itself must be

tight, and all protective devices to be put on from above.

The most reliable are the ring connectors as in

Swiss patent “The sealing element of gloves for a dry suit” (SN 1 9970013 1 1 19970602, WO 1998CH00217 19980525). It proposes to connect the sleeve and glove of the suit with joint rings sealed to them and

the sealing ring installed between them. Direct

the use of such a connector in an insulating suit for separation into a jacket and pants is not advisable, because in cross section, the human body has an oval shape. And the use of rings on the joint will lead to the appearance of large gaps in the abdomen and back. There will be no fit of the rings to the body and the jacket with trousers in this place will take the form of a bell. However, the use of such a connector in the region of the belt makes it possible to completely disconnect its elements, which are convenient when donning and sealed when using O-rings. The range of pressures they withstand completely covers the permissible for humans, and the ring shape is well suited for any manufacturing technology. O-rings are commercially available and this ensures

interchangeability. A failed ring can always and easily be replaced with a new one. In addition, currently developed

technologies and materials for o-rings, which allow their use in frost or heat, in aggressive solutions and environments when ordinary rubber rings fail. Already, such o-rings are widely used for connecting sleeves with gloves in suits of astronauts and divers.

The disadvantage of this connection is unnatural circular expansion in the wrist. But this disadvantage is easily turned into an advantage. To do this, you need a ring connector, which

is perpendicular to the axis of the arm, tilt until it touches the body or underwear. A large round opening will remain and there will be a fit to the body.

The closest is the solution in the US patent for the invention of "Swivel joint for wetsuits" US2003213041 (A1) - 2003 - 1 1 -20. It offers an annular connection of elements suit, which can also rotate. For this, ball bearings are integrated in them. To increase reliability, the ring joint has a multi-stage ring seal system. All

the joints are located on the sleeves and trousers of the armored wetsuit, and the movement of the limbs should be carried out by an exoskeleton drive. It is important that the claims relate to swivel joints, and a suit with their location is given as a good example. From figure 1 it also follows that the suit has a transverse ring connector that divides the suit into a jacket and pants. Without this connector, it is impossible to get inside the suit. But the transverse ring connector is almost not adjacent to the diver's body and requires a significant increase in its strength. In this design, the suit loses its streamline and is poorly adapted for work and swimming under water. It has a lot of ring connections on

limbs that are assembled in advance and are not intended to be disassembled as in the Swiss patent "Sealing element of gloves ...". The very complex design of the wetsuit is not very suitable for drying after use.

Utility Model Disclosure

The utility model is based on the task of creating

structurally simple, convenient and reliable in operation insulating suit for safe work in difficult conditions and in an environment aggressive for humans.

The task is achieved by the following technical solutions. The main purpose of the suit is isolation from the effects of the external environment. But in various conditions, when leaving the danger zone and for rest, breathing relief, a comfortable temperature or the removal of various protective devices and gloves are necessary. Therefore, the suit is offered collapsible with removable or folding

elements, and all protective devices (hard hat, shields, durable a tarpaulin suit) is best worn on top of it. Under the suit is mainly underwear, which serves as protection against hypothermia or overheating. Other life support systems: air supply, regeneration of the internal air-water environment or the same thermoregulation is better to place on a suit and attach them with pipes or valves.

The most important characteristic of an insulating suit is its “self-confidence” or donning without assistance and of course, taking off. To do this, it is divided into a jacket and trousers, which on the connector have connecting rings hermetically fixed to the material of the suit. The annular connector between the jacket and trousers is made so that the upper part in front of the chest envelops, and the lower part of the back of the lower back or buttocks. This is done in order to reduce the gap between the oval body of the person (in cross section) and the annular connector. With this arrangement of the connector, the user can access any part of it and with his hands he can easily connect or disconnect the jacket and trousers. The ring connector resembles an embroidery hoop, and o-rings are installed between its connecting rings (hoops). AT

the present o-ring is practically

the only inexpensive, generally available and replaceable product that provides tightness and quick disconnect of connections in all pressure ranges necessary for a person.

The same solution is proposed for gloves and / or shoes, in which the opposite parts of the connecting rings, which are most distant from the limb body, are inclined to the body to reduce the gap.

The execution of the insulating suit by the team of individual elements allows us to reduce the number of its sizes, taking into account the anthropometric data of each individual. Are possible

various combinations of aspect ratios (lengths and fullness) of the jacket and trousers, as well as the size of gloves and shoes. Replaceable elements can be different in quality, price and specialization, when the suit is designed to perform operations in difficult conditions or in an aggressive environment.

This design of the insulating suit is also convenient for

compliance with hygiene requirements. After disassembling into individual elements, it is easy to dry and disinfect the inside and out.

For the convenience of putting on a suit, one connecting ring in pairs of mating elements has a device for fixing on the human body to prevent displacement along the torso or along the limbs. On trousers it can be braces (help), and on the limbs - straps.

Brief Description of Drawings

Figure 1 shows an insulating suit - front view and side view. Figure 2 shows a section of the annular connector between the jacket and trousers on an enlarged scale.

Utility Model Embodiments

The insulating suit (Fig. 1) consists of a jacket 1, trousers 2, removable gloves 3, shoes 4 and a helmet 5. Shields 7 and 8 are fixed on the outside of the suit. The individual elements of the suit have ring connectors 9, 1 0, 1 1 and 12. An annular connector 10 between the jacket 1 and the trousers 2 is shown in FIG. It consists of connecting rings 13 and 14. The connecting ring 14 has a sealing ring 15 in the groove on

a cylindrical surface and a sealing ring 16 in the groove on the end surface. To prevent axial displacement and opening of connector 10, Velcro tapes 17 are used. For mechanical seal, not only fixation from mutual axial displacement is necessary, but also preload. There are many designs of clamps with preload. In figure 2 they are not shown. The remaining ring connectors are arranged by the same principle, which are placed perpendicular to the axis of that part of the body where alignment is necessary, or obliquely.

Putting on a suit is made as follows. A man in underwear first puts on pants 2 and pulls them up.

The crotch serves as the restriction below, and the suspenders are fixed on top 6. Suspensions are reminiscent of it. Then

jacket 1 is put on with a detachable or folding helmet 5.

The connecting ring 14 is inserted into the connecting ring 13. The location of the connector 10 allows you to reach any part of it with your hands and perform the docking yourself. Then

gloves 3, shoes 4 and helmet 5 are docked, if the latter is detachable. All of these actions do not require significant effort, because O-rings work in the proposed design

insulating suit with small pressure drops. Joining the elements of the costume can be done manually and quickly. With large pressure drops or end-face sealing

surfaces it is possible to use clamps with compression, which is easily feasible.

Industrial applicability

The list of technical solutions showed that

the proposed insulating suit can be quite simple, convenient and reliable in operation in the most difficult conditions and in various aggressive environments. Its practical implementation is not in doubt, because inherent decisions comply

existing and proven manufacturing technologies.
