Description

Rescue sleeves for use on buildings

technical field

The present invention relates to a rescue system for evacuating people trapped in a high-rise building in the event of an emergency such as a fire or an earthquake, which is disclosed in the patent application PCT/IL00/00477 filed on August 30, 2001 by the applicant Publication No. WO01/62138 (hereinafter referred to as International Patent), the contents of which are hereby incorporated by reference.

Background technique

The system disclosed in this international patent and its further improvements (the applicant's Israeli patent applications No. 139549, No. 139550, No. 145935, No. 147975) are all fixed, that is, permanently installed on the building for use by evacuated survivors.

Therefore, rescue from common high-rise buildings often relies on the aerial ladder of traditional fire trucks. These ladders have limited evacuation capabilities due to height and evacuation speed.

It is therefore an object of the present invention to provide a motorized rescue cannula system.

Yet another object of the present invention is to provide a motorized rescue casing system with a self-contained, remote controlled, jaw type system for anchoring the casing to a window frame of a high rise building.

Contents of the invention

A rescue system for evacuating persons through a window frame of a high-rise building, comprising a rescue sleeve collapsible between a retracted standby position and an extended tilted-to-the-ground position; means; and a compartment for receiving the bushing, and a system for operatively anchoring said compartment to said window frame in a self-supporting manner.

Detailed ways

As shown in FIG. 1, the rescue vehicle 10 is equipped with a hydraulic hanger 10a, which supports and raises a rescue casing 12 through a beam 10b. The beam is freely inserted into the channel 16 and can be retracted from the channel as shown below.

The capsule 12 has, on the exit side, a rescue sleeve 18 (shown in FIG. 2 ) in a folded ready position, for example of the type disclosed in the international patent.

The other side of the compartment 12 , the entry side, houses the ram jaw system for breaking glass, indicated at 20 .

System 20 includes two identical symmetrically arranged ram head displacement subsystems 22a and 22b, which operate in parallel, and are described below with reference to FIGS. 5-8. The subsystem 22a is mainly described, and the other subsystem 22b is the same.

Referring to FIG. 5, a pair of L-shaped rails 24 and 26 are provided. Rails 24 and 26 are secured to rails 28 and 30, respectively. Rail 28 is carried by rollers 32 and 34 on rails 36 and 38 respectively. Likewise, rail 30 is carried by rollers 40 and 42 on the same rails 36 and 38 . In this way, guide rails 24 and 26 can move in parallel toward or away from each other.

The mechanism for effecting movement of rails 24 and 26 includes cylinder 44 and piston 46 . Cylinder 44 is supported by brackets 48 and 50 (FIG. 6) rigidly secured to rails 36 and 38, respectively. Piston 46 is connected to rails 24 and 26 by two pairs of scissor arms 54,56 and 58,60. Arms 54 and 58 are pivotally connected to piston 46 by suitable mounting plates 62 and 64 respectively, and to rail 24 by standoffs 66 and 68 . Arms 56 and 60 are pivotally connected at one end to plates 62 and 64 , respectively, and at the other end to rail 26 via mounts 70 and 72 , respectively. Thus, extraction of the piston 46 will move the rails 24 and 26 away from each other, and retraction of the piston 46 will bring the rails 24 and 26 closer to the mating position, as shown in FIG. 2 .

The rail 24 of subsystem 22a and the rail 80 of its counterpart subsystem 22b (see FIGS. 4 and 6 ) carry one 82 of the two ram jaw heads, while the rails 26 and 81 carry the ram jaw head 84 .

The ram jaw head 82 is preferably triangular in cross-section, having a blade front end 82a and an upstanding surface 82b (see FIGS. 5 and 6 ). The ram jaw head 84 has the same structure.

Finally, a floor 86 supported by guide rails 26 and 82 (FIG. 7) is provided at a lower level between subsystems 22a and 22b, through which the rescued person can reach the entrance of the rescue casing 18 from the room window. For greater safety, the corrugated cover 88 can be used to block the line of sight so as to avoid the fear of survivors when sliding down from a high place.

Referring to Figure 2, there is shown a compressed gas container 90 which is used as a stand-alone energy source. The compressed gas operates the piston 46 at the appropriate time and drives the release/coil rescue sleeve 18 . It will be described below.

Accordingly, the gas container 90 is connected to the air cylinder 44 by means of suitable valve remote control (not shown) and also to the schematically shown upper and lower cable winch units 92 and 94 (see international patent for details).

The rescue system operates as follows:

The cabin 12 is connected by a beam 10b at one end of the hanger 10a to the channel 16, which is then raised and close to the alignment window from which evacuation takes place (see Figure 2). It should be emphasized that the hydraulic hanger on the vehicle can be designed to reach a height higher than that of ordinary fire truck ladders.

Operating the hanger 10a causes the rams 82 and 84 to break the window covering, which may be a glass curtain wall and/or a glass window.

After the penetration has been achieved, the cylinder 44 is filled with compressed gas provided by the container 90 and the opening operation of the ram jaws is started after obtaining the order of the rescue team on the vehicle 10 .

Of course, any equivalent drive could be used, such as a battery operated motor.

Thus, the ram jaws 82, 84 will be securely anchored to the upper and lower sides, respectively, of the concrete frame of the window (Figs. 3 and 4). Also, the cabin 12 is self-supporting on the outer walls of the building.

After the beam 10b is retracted from the channel 16 and folded back on the hydraulic hanger 10a, the rescue vehicle 10 can leave the scene.

At this point another remote control command can be issued, effectively ejecting the rescue sleeve 18, for example in the manner described in the aforementioned international patent.

Survivors are able to enter the entry end of the compartment 12, through the floor 86 towards the opening of the casing 12 and slide down.

In the embodiment shown in Fig. 10, the inclined sleeve is replaced by a helical sleeve 118, which is described in detail in the Applicant's Israeli Patent Application No. 145935 or No. 147975. The details and operation modes of the remaining structures are already clear from the above description, and will not be repeated here.

Those skilled in the art can easily make various changes and modifications to the present invention without departing from the spirit and protection scope defined by the claims of the present invention.
