Description

The invention relates to diving equipment, namely to space suits.

. Known spacesuit for autonomous

breathing apparatus containing a shell and a soft helmet of the type that is masked * with a mask, while the hood is made of a composite of two sealed parts, reclining on the chest and on the back. Spacesuit worn over the hood connector that joins ¹⁰ schiysya with the connector shell £ G | .

The disadvantage of this spacesuit is that it is unsuitable for connection with a hard helmet.

The spacesuit is also known; it contains a sheath with a pressure connector and a neck ring and a helmet that joins the shell through a neck ring and is made of detachable facial and occipital parts fastened together.

The disadvantage of this spacesuit is that it is inconvenient for independent and quick donning, the size of the neck ring should be sufficient for passing

head, and the entrance to the helmet or the length of the opening should be such that after wearing the shell, you can start the head in the neck .30

ring, it requires an elongation of the neck, which then, to avoid lifting the ring up with excessive internal pressure, is compensated by a tensioning system. All this leads to an increase in the size of the helmet, and hence to an increase in weight and ventilated volume.

The aim of the invention is to provide the convenience of independent and quick donning and at the same time using a hard helmet of small volume.

This goal is achieved by the fact that the neck ring is made, the composition is; The two semi-rings, anterior and posterior, the rear half-ring attached to the back of the helmet, two detachable parts of the front half-ring attached to the ends of the cage's pressure seal, the half-rings connected by hinges an elastic lining attached by a flat part to the external contour of the joint, so that its compressed ends are fastened at the connector of the front semiring.

FIG. 1 spacesuit assembled with a helmet, general view; in fig. 2 is a section A-A in FIG. in fig. 3 - section BB in fis.1; in FIG. 4 — section B — B in FIG. 2} in FIG. 5 - sealed fitting of the spacesuit with the front part removed, a helmet.

The spacesuit contains a protective sheath 1 with a pressure connector 2, for example with a zipper. To the shell 1 in its neck part is attached a neck ring 3, which is made of composite - from the back half ring 4 and two parts 5 and 6 of the front half ring.

Parts 5 and b of the front half ring are provided with grooves 7 for the projections 8, which the half ring 4 is equipped with. High and low 5 have 8 on the outside of the cavity 9 for accommodating the stops 10 in the grooves 7. To the half rings back 4 and front ', composed of parts 5 and 6, is attached to the cervical 20 part 11 of the protective sheath and partially elastic lining 12, which has a comma-shaped cross-section. The cervical portion of the 11th lining 12 is tucked into the semirings by arcuate plates 13. At the 25 junction of parts 5 and 6 of the front half ring there is a lock 14 and the ends of the 15th hot seal 2, the ends 16 of the lining 12 are also fixed. 4. The ends of the helmet part 17 and the parts 5 and 6 of the front half-ring form the contour of the joint 18, along which the removable front or front part 19 of the helmet is sealed. In the upper rear part 17 of the helmet, the bow 20 is fixed, and in the front part of the removable part 19, the hook 21 that is included in the handle 20 is fixed. For the connection of parts 17. and 19 of the helmet, the spacesuit is equipped with a tension ..... with a new lock 22. 40

The suit is worn as follows. ,

The shell 1 is put on the body through the 'sealed connector 2. The occipital part 17 of the helmet is pulled up to the head, the back half ring 4 is tightened to the neck, the pressure outlet 2 is closed with the lock 14, while the parts 5 and b of the front half ring turn on the lining 12 and on the neck 11, the projections 8 are driven into grooves 7. When the front semiring (parts 5 and 6) is completely closed, the stops 10 enter depressions 9, after which the back half ring 4 and the front half ring form a rigid connection, thus representing a solid and rigid ring. The ends 16 of the lining 12 at the cut of the front ring, at the junction of its parts 5 and b, are compressed, the lock 14 is sealed 2

its flat back part tightly "pressed against the flat part of the lining 12, thus sealed.

After that dock the front part 19 of the helmet with its occipital part 17. The hook 21 is inserted into the bow 20, lower the front part 19 of the helmet onto the contour of the joint 18 and tighten it to the occipital part 17 of the helmet with the help of the tension Lock 22. The suit is wearing, the diver is ready to go.

Hoses for breathing and their supply to the spacesuit is not shown.

They can be attached to different parts of the spacesuit.

Performing a neck ring in a spacesuit composite provides convenience. putting on and using a hard helmet with a relatively small volume. The ability to remove the front of the helmet provides additional benefits in terms of ease of operation, i.e. while waiting for dive, takeoff, etc.
