The invention relates to discharge devices of the type latch, for example, used for fastening objects (cargo) when delivering them as part of the transport cargo vehicle (THC) "Progress" on Board the International space station (ISS) and the use of crew members when performing operations on Board the ISS during extravehicular activity. This device can also be used in all sectors of the economy for fixing cargoes, including in the conditions of the aquatic environment.

The famous design of the locking mechanism intended to ensure the fixing of items (goods) on the two rails of a space object, including its supporting structure in the form of a rigid platform is rigidly mounted on the clamps number greater than or equal to three (application No. 2002101982 class B64G1/66).

As the closest analogue is selected design clips on to patent No. 2132006, MPK7: F16B 2/26, B60R 11/00 containing base, made in the form of a plate elongated in shape, provided with at least one means of attaching the base to a supporting surface, and means mounting tape, made of elastic material and arranged along the large side of the base.

The main disadvantage of existing designs of clamp is that the wiring and cables clamps in the environment of outer space (when animal is low and abnormally high temperatures in the range from -200C to +200C) may be susceptible to the damaging effects of the environment. In addition, existing designs retainer suggest the presence of and the fixing of the base of the clamp to a supporting surface, in space on the spacecraft to carry out much more complicated, in addition, these devices are more complex and more energy-intensive to manufacture.

The objective of the invention is to improve the reliability of the device during long-term operation in space when the abnormal temperature increase of the resource.

This task is solved in that the proposed device lock, do not use hard-coded fixed base, contains rings with hooks connected to the hooks adapter, and the adapter are coming to the hooks flange of larger diameter, and the flange of smaller diameter, the retainer also includes a bearing spring, their ends wound on the ends of the adapters, as well as the case of armenoi fabric, worn over the spring, which is tight from hooks up to the shoulder of the larger diameter of the adapter is screwed arimina thread.

Kimenyi case not only protects the latch from dust and other foreign particles into the space between the joints of coils stretched the suspension spring, but also serves as a retainer extremely stretched the suspension spring.

Use arimidex h the HLA and thread allows the latch to operate reliably, not only at high temperatures (-200C to +200C), but in other environments, for example in the aquatic environment, which improves the reliability and durability of the device.

Figure 2 on an enlarged scale shows an external view of the device with the left hook 1.

The hooks 1, 2 devices are mounted, for example welded argon-arc welding, the ring 3, and 4, for example, oval. One ends of the hooks 1, 2 is placed in the cylindrical hole of the adapter 5, 6 and fixed therein, for example welded by welding. A cylindrical adapter 5,6 made in the form of two cylinders of different diameters with two pairs of ribs 7, 8 and 9, 10, thus coming to the hooks 1,2 flange 7, 8 of the adapter 5, 6 have larger diameters than the other flange 9, 10. The cylindrical adapter 5, 6 to the junction with hooks 1, 2 wound suspension spring 11, and the diameter of the small cylinder of the adapter 5, 6 coincides with the diameter of the bearing spring 11. On top of the supporting springs 11 to the junction of hooks 1, 2 with the adapter 5, 6 put the cover 12 from armenoi tissue (e.g., round). On top of the cover 12 from armenoi fabric tight clockwise from the hooks 1, 2 to Boo the ticks larger diameter adapters 5,6 wound arimina thread 13 to prevent retraction of the cover 12 when the tension of the elastic retainer. The length of the retainer may be of any desired size.

When using this device the operator (astronaut) takes the device in the glove thumb over the ring 3 or 4 and fixes the hook 1 or 2 for the constructive elements of the cargo or the handrail, then 1 thumb over the ring 4 of the hook 2 stretches the latch using the standard for astronaut efforts (300-500 grams), fixes a load supporting spring 11 release and fixes the hook 2 of the latch for the handle or hook 1 release by providing secure mooring cargo to the rail.

The proposed device is easy to manufacture, is composed of a minimum number of parts and reliably (with a five-fold margin of safety) in the long run. Conducted full-scale tests showed the ease of use and reliability in operation when the temperature in the space.

All parts of the device (rings, hooks, adapters) can be made from a different view stainless steel, the spring may be made of a different view of the spring steel, the device can be processed by the method of elektrohimpribor to make the product marketable and also removing the oxide tint in places of welding connections.

All this makes the device more durable anticorrosion the grave and increases reliability for long term use.

The latch containing rings with hooks connected to the hooks adapter, wherein the adapter are coming to the hooks flange of larger diameter, and the flange of smaller diameter, the retainer also includes a bearing spring, their ends wound on the ends of the adapters, as well as the case of armenoi fabric, worn over the spring, which is tight from hooks up to the shoulder of the larger diameter of the adapter is screwed arimina thread.
