Description

Rescue system for high-rise building {RESCUE SYSTEM FOR HIGH-RISE BUILDINGS}

Various solutions to this aspect have already been proposed. Thus, for example, U.S. Patent No. 4,240,520 (1980) discloses a fire evacuation tunnel used to escape skyscrapers. The tunnel is an extensible accordion corrugated tube made of nylon or canvas padded on its inside, a ring attachable to the evacuation opening of the building at its upper end, a lower end of the tube with a soft landing pad, and an outlet It includes, the person who slides down or down the tunnel at the exit can walk to the ground.

Another example is US Pat. No. 4,099,596 (1978), which discloses a device having a landing pad at its bottom and including a normally folded flexible tube that extends to a vertical chute condition, the inside of which is snagging. The slippery, deployed tube is formed to have an elastic confinement at a continuous vertical level to protect the descent of the person descending from the free fall to the home safety speed.

Other less relevant examples are U.S. Patent Nos. 4,398,621 (1983) and 4,580,659 (1986), which have proposed mesh tubes that allow escapers to descend themselves.

None of these have evolved into a practical system, primarily due to inherent design difficulties. Thus, the teachings of the '520 patent do not provide a solution to the problem of re-installing the tunnel after use, but also provide a solution to the consumption of storage space in the case of skyscrapers.

The system proposed in the '596 patent is operatively installed in a vertical position, which makes the refugee practically dangerous despite the proposed antisnagging means.

The present invention relates to a rescue system for evacuating people trapped in a tall building in an emergency, typically in a fire.

More specifically, the present invention relates to a fire evacuation device using a chute or tube through which people slide down a building.

Accordingly, it is an object of the present invention to overcome the deficiencies of a fire evacuation system based on conventional slide tubes or slide chutes.

Another object of the present invention is to provide a system in which the fold of the tube into the standby position is achieved in a regular and reusable manner.

It is a further object of the present invention to provide a mechanically actuated release means for quickly and reliably locating a tube from a standby position when needed in an emergency situation.

Thus, according to the present invention, a rescue system evacuates people trapped in a high-rise building by sliding down the rescue sleeve, which system is a sleeve composed of sections, each section being made of a plate reinforced by a circumferential rigid support member and These sections are connected to each other to form a continuous shell; Along the sleeve, one or more pairs of cables, one through the lower parent point and the other through the upper parent point; A winch system that winds the cable to a designated location on the floor of the uneven structure of the structure so that the sleeve is folded in a compact package; Spring-activated means for selectively discharging and deploying the sleeve down to the ground level at which the sleeve is tied to the fixture (s).

Other novel features and other objects of the present invention will become apparent from the following detailed description, description and appended claims set forth in conjunction with the accompanying drawings.

1 illustrates a high-rise building 10 (house or hotel) in which a fire occurred.

The rescue sleeve or chute 12 is released as described in more detail below, and is routed by cables 14, 15 to any stable object such as a parked vehicle, a tree, or a street lamp (column 16, 17). Briefly shown]. Multiple auxiliary fixing cables 18 are available for better support and greater safety, and although preferred and used as shown and further described below, are not required.

The sleeve 12 is mostly made of tapeworm structure, ie a series of sections 20, which sections are made of strong plates such as nylon, canvas cloth, sealed together and rigid rings, generally indicated at 22 (Fig. 4). Will be further described (see FIG. 2).

However, at the bottom, the structure of the sleeve 12 is half open (section 20 '), preferably intended to stop and absorb the sliding motion of the rescued person (shown in broken lines) using the sleeve. Self-expansion cushion 24 may be provided.

Also provided are (at least) a pair of tension cables 26, 27 extending along the entire sleeve 12. The cable 26 passes through the eyelets 28 installed one by one of the rings 22 on the lower side. All eyelets are preferably pivoted through a U-shaped bracket 30 welded to each ring 22 (FIGS. 3A-3D).

The plug 26a is attached to the end of the cable 26.

The same configuration exists for the cable 27 that extends through the eyelets 28 in a staggered manner with respect to the cable 26.

4A and 4B show yet another structure in detail. This structure relates to the manner in which the sleeve sections 20 are sealed to each other and to the ring 22. Thus, the edge of each section bends radially outward, folds against itself, and secures with stitches S1 and S2, leaving the extension facing backwards. The ring 22 is then assembled by a circular wrapping 32 of cloth surrounding the ring and secured to the extension by stitches S3 and S4.

Of course, the bracket 30 for the eyelets 28 penetrates outward of the wrapping 32 (FIG. 4B).

The configuration shown in FIG. 5 may be employed such that the sleeve 12 is bowed when the sleeve is left away from the building 10. When in the folded state (see below), securely connect between the eyelets of the skipped upper cable 27 with an additional limiting cable 34 to limit the distance between each ring from the upper point to a preset length do. Due to this, when unfolded, the sleeve 12 forms a bow-shaped knee section 12a. The number of these teeth 12a is determined along the entire height upstream of the sleeve (i.e. the number of layers of each bill, etc.), and in total, depending on the total number of finally desired bends of the sleeve.

As already mentioned, an auxiliary fixing cable 18 (FIG. 1) may be needed. For this purpose, a second series of pivotable eyelets 40 is employed (FIG. 6), which are located radially in the horizontal plane, are arranged along the sleeve and mounted in some ring 22 apart.

As further shown in FIG. 6, the shape of the eyelets is beneficial, such that the auxiliary securing cable 18 can be configured as a loop, which is the concept that after use, the cable can be cut off and completely removed from the sleeve. This is important for smoothly refolding the sleeves for reuse without having to pay special attention to orderly gathering these cables.

As described below, the cable 18 is reinstalled through the service opening (sliding doors 74 and 75) in a later step with the sleeve folded.

Reference is now made to FIGS. 7 to 12. On every floor of the building 10, a compartment, usually indicated by reference numeral 50, is installed next to the outer wall 10a, which is associated with a funnel extension 10c and an elliptical opening 10b (FIG. 13).

After the cables 26, 27 are completely rewound by the respective electric winch systems 52, 54, the rescue sleeve 12 is shown to be in a folded standby state.

The cable 26 passes through the guide tube 56, for which a slightly flared opening 56a is provided. The same applies to the pipe 58 for the cable 27.

Coil springs 60, 62 acting against a common backing plate 64 (shown in FIG. 9) are installed, the backing plate having a surface formed such that the sleeve 12 is accordion-like. Fold into

The backup plate 64 has an inlet 64a which is equal to or larger than the diameter of the sleeve 12.

Since the distance between the tube 56 and the tube 58 is larger than the diameter of the sleeve 12 and the eyelets 28 are in an alternating order with respect to the lower cable 26 and the upper cable 27, the sleeve section 20 ) Is folded in a zigzag form without overlapping, saving storage space.

Compartment 50 is made of a metal structure and includes a first weatherproof sliding door 70 (shown in FIG. 10), a second sliding door 72 facing the interior of the building, and a compartment 50. Two pairs of third service sliding door systems 74a, 74b, 75a, 75b, located on either side of the system, are provided (see FIGS. 8 and 12), which use a rescue sleeve and After cutting and removing the auxiliary cable to smoothly fold it into the standby position without any problem, it functions to enable access from the side to reconnect the auxiliary fixing cable 18.

Operation of the rescue sleeve system is illustrated in FIG. 13. Thus, the emergency sliding door 70 is pulled sideways (shown in FIG. 10) and the winch systems 52, 54 are released to freely rotate their drums. As a result, under the force of the springs 60, 62, the backup plate 64 is fired (to the left of FIG. 7) so that the folded sleeve is released out through the opening 10b and the funnel section 10c provided therefor. Laid on).

Now, the position of FIG. 14 is reached, in which the sleeve 12 is freely suspended except for the knee-shaped section (s) 34 and begins to form the sleeve towards the operating position of FIG.

The auxiliary cable 18 (provided attached when the sleeve is in the folded position as described above) is freely suspended as shown, ready to be held in the hands of the rescue team and constrained to any available fixture. The free end of the sleeve is constrained as described above with reference to FIG. 1, making the system ready for its lifesaving purposes.

While the foregoing description includes many features, these should not be construed as limiting the scope of the invention, but rather as examples of preferred embodiments. Those skilled in the art will envision other possible variations that are within the scope of the present invention. Accordingly, the scope of the present invention should not be limited by the illustrated embodiments but by the appended claims.
