The proposed lock objects in zero gravity refers to space technology, namely the means of ensuring the activities of the astronauts in weightlessness, including open space, in particular to the means of securing items to the body of the space object or each other.

The proposed latch can be effectively used in the diving operations, transport, and other industries production and business activity, as well as in domestic operations.

In the process of life and work in zero gravity, you need to fix, fix all the objects that surround astronaut or which it uses to avoid uncontrolled drift or separation from the space object and lost.

For fixing, there are various ways and means: mechanical, magnetic, adhesive; elastic fabric, elastic bands, ribbons, cords. The materials used for fixation, the demands for the preservation of their physical properties under the influence of space factors: vacuum, temperature, radiation and other

One way of fixing is binding items fabric cords, ropes. The use of these funds, tying knots for astronaut in spacesuit under pressure, with limited mobility is reduced tactile sensitivity of the fingers in the glove - extremely time-consuming task with guaranteed positive outcome. Moreover, in practice, revealed the same effect as weakening, the blooming of nodes in weightlessness and the weakening of all the leash.

A device for fixation of the structural elements on the body of the spacecraft (RF patent 1804423)providing a fixation band-shaped, flat design elements on two parallel rails of a spacecraft using staples, U-shaped, one end of which is made rigid with the C-shaped profile, and the other end is made with a spring-loaded protrusion. This device ensures the fixation of the subject only to two parallel handrails and captures only a flat, ribbon-like objects, not fixation of objects of various configurations to any element of the design of the space object.

Known use in engineering wire to lock against unauthorized unscrewing the locking screw connections. The completion of the operation of twisting the wire in this case is carried out using tools such as pliers, which is not acceptable due to the limited locomotor capabilities of the astronaut in a spacesuit (Handbook of metal. Volume 2., s. The motor cycle", Moscow, 1958) (prototype).

The task of the invention is to provide the giving of the universality of the latch due to the fixation of objects of various configurations to any structural elements of the space object in the open space astronaut in a space suit.

The solution is achieved by the fact that the latch is made in the form of a wire in a non-metallic shell with rings on the ends, the diameter of which is commensurate with the size of the fingers narutoi gloves of the suit under excessive pressure, and the wire material has the property of residual plastic deformation.

Figure 1 shows the initial state of the latch.

Figure 2 shows the cross section of the latch.

Figure 3 shows one of the uses for the release.

On the figures:

1 - latch;

2 - wire;

3 - non-metallic sheath;

4 - ring;

5 - fixed object;

6 - the handle of a space object;

7 - twisting.

The latch 1, for example, annealed copper wire 2 has a non-metallic shell 3, for example, PTFE and rings 4.

The latch is used as follows. Astronaut in spacesuit Flex the latch 1 in the form of a fixed object 5 together with the structural element, for example, a handrail of a space object 6 to which the subject is attached, Prodavat fingers in rings 4 and ties up the loose ends in the release twist 7 thereby effecting the fixation of the object.

Due to the residual plastic deformation of the material of the retainer securing the subject happens to be sturdy, durable, stable, resistant to factors KOs is practical space, twisting can be easily disassembled by the astronaut, and the latch can be used again or repeatedly.

Steps to use lock available and convenient to carry astronaut in spacesuit under overpressure conditions of weightlessness that follows from the experience of implementing operations extravehicular activity.

Lock objects in the space containing the wire in a non-metallic sheath, characterized in that at the ends of the retainer ring provided along the diameter commensurate with the size of the fingers narutoi gloves of the suit under excessive pressure, and the wire material has the property of residual plastic deformation.
