Description

1 65168

This invention relates to the rescue of objects or people in need in emergencies. More specifically, the invention relates to a rescue sock module that can be used in such rescue operations to rescue people or evacuate objects from a state where conditions are dangerous (fire, etc.) to a space below where assistance is available.

Such an apparatus generally comprises a rescue sock made of elastically deformable material, open at both ends, which is attached to the partition of the space from which persons or objects are to be evacuated. When the elastic sock is not in use, its diameter is smaller than the circumference of the people or objects wearing it, if necessary; thus, the sock effectively brakes descent even from high altitudes, up to several tens of meters.

The second sock, which does not stretch longitudinally but deforms transversely, is usually located inside the first sock; its purpose is to prevent the abnormal elongation of the elastic sock when it is under load during use.

Finally, a third sock made of refractory material can be placed around the first two socks to protect them in the event of a fire.

Such safety equipment is commonly used as life-saving appliances not only on the partitions of flats or on the floors of balconies in apartment buildings, but also on the platform of fire escape ladders, ships or oil rigs; rescue socks are equipped with special fastening devices in each case.

Although it has already been technically possible to develop very long life socks, it has been found that there is a need for life sock modules that can be connected to each other at the ends; in this case, the length of the life jacket thus assembled can be easily and simply adapted to the height of the structure to be provided with the sock.

It is an explicit object of the present invention to solve this problem.

To this end, the invention proposes a sock module for emergency rescue operations of the following type: inside the first flexible, elastically deformable tube is a second flexible tube which deforms in the transverse direction but is non-stretchable in the longitudinal direction; this life jacket is characterized by the fact that the pipes in question are connected at their periphery both at one end and at the other point at a certain distance from the opposite end; and that, at the end where the said pipes are connected to each other, the connecting or fastening pieces are placed around the outer pipe, and at the point where the said pipes are connected to each other at a certain distance from the opposite end, connecting pieces which may or may not be This allows the free end of the lifejacket to be connected to the end of a second similar sock where the tubes are connected to each other, and the lifejacks to be secured to each other by means of connectors designed for this purpose at a distance from the free end of the first sock and the second to the adjacent end of the sock.

These couplings can be of any technical type, but they must be strong enough to withstand not only the weight of the rescue socks connected to each other, but also the significant weight gain caused by people or objects wearing the rescue socks. These connecting pieces can be, for example, hooks with a spring, the opposite side having either similar hooks or rings. Of course, all known technical fastening methods can be used, but preferably with safety or locking devices.

The connecting pieces are fastened, for example, around the outer tube of the rescue sock by means of a flexible rim sewn to it, which has hooks, rings, hooks or the like provided with a spring. Preferably, said resilient rim also acts as a joint between the inner and outer tubes, so that the tubes are sewn both to each other and to this rim.

Alternatively, the fastening piece of the rescue sock according to the invention may be a mere rigid ring around which at least the outer tube of the sock, which is sewn to the outer tube and / or the inner tube, is wound. Such a rescue sock is used at the top of a rescue channel formed by a plurality of interconnected sock modules, so that a ring attached to it provides support, e.g. from the edges of a circular rescue opening on a platform or balcony.

The accompanying non-limiting drawings illustrate one embodiment of the invention. Of these drawings 4 65168, Figure 1 shows a side view of a toy sock module according to the invention; Figures 2a and 2b show the adjacent ends of two rescue socks according to the invention both before and after they are joined together; Figure 3 is a perspective view of the top of one life jacket; Figures 4 and 5 show in more detail on a larger scale the top of the same sock; Figure 6 is a fragmentary view showing an alternative of the top of a life jacket according to the invention.

The sock module according to the invention comprises a flexible outer tube 1 made of an elastically deformable material, inside which is a flexible tube 2 which is deformable in the transverse direction but non-stretchable in the longitudinal direction.

According to the invention, the tubes 1 and 2 are sewn to each other perpendicular to their axis, both from one end of the tube and at a certain distance from the opposite end of the tube. More specifically, as shown in Figures 3-5, a rim 3 of durable material is sewn into the tubes 1 and 2; the rim acts as a connector for these pipes.

The parts of this rim which form the openings 4 are not attached to the pipes 1 and 2; they are fitted with spring - loaded metal hooks 5.

As can be seen from Figures 2a and 2b, the end-of-life sock modules according to the invention are connected end-to-end by placing the free end 6 of the second sock, i.e. the part which separates the rim 3 from the end where the pipes 1 and 2 are not connected to each other. The opposite metal hooks of both socks are then attached in pairs 5.

In this way, it is possible to easily adjust the length of the rescue channel formed by the interconnected socks to the height of the place from which objects or people are to be rescued by this method.

The free part 6 can be formed by a mere extension of the outer tube 1, which extension cannot then be reinforced by the inner tube 2. Optionally, the extension can also be formed in the shape of a funnel as shown in Fig. 2a.

In order to facilitate the installation of the rescue channel formed by the end-connected socks according to the invention, it is most convenient to provide the upper level sock with a metal ring 8 (Fig. 6) around its upper part, instead of the rim 3, around which the outer tube 1 is wound inwards and sewn attached to the outer tube 1 and the inner tube 2.

In this case, no complicated fastening systems are required, but it is sufficient, as shown in the figure, for the ring 8 to be placed on the support part 9 surrounding the rescue opening 10, whereby the sock in the ring and the sock modules attached to it are ready for use.
