Description

The invention can be used for emergency descent of people from the upper floors and the roof of tall buildings in emergency situations.

A device for saving people is known (application No. 2002119782/12, class A62C 3/00 dated 07/22/2002), which is made in the form of two rollers and a mesh web stretched between them in the form of an endless belt, and the whole device is suspended on the axes of rotation of the upper rollers along the vertical wall of the building on thrown and fixed cables with the possibility of a fixed movement of the device along the cables within the required limits, in addition, flexible pockets are attached to the mesh web, and the device is folded, sheathed mounted on a cut of the roof of the building I am.

Due to the fact that the described device is mounted on a slice of the roof of the building, in order to eliminate possible extreme (emergency) situations, it is necessary to have one or more such devices on each building. For a modern city with a sufficiently large number of high-rise buildings (hundreds to thousands of pieces), the use of such devices is not economically profitable - very expensive. In addition, another problem closely related to this drawback arises: the difficulty of timely periodic certification (performance checks, quality, storage conditions, etc.), for example, once a year, of so many devices for saving people.

The prototype is a rescue device (GB patent GB 536535 dated 05/19/1941) containing a rope (rope) stretched between two spatial points so that it can be tilted, placed vertically and slide, the device holds the rope and touches it at two spatial points . The named device has hooks, holes or something like that at two points placed so that ropes, chains, etc. can be fixed. for tension. The ropes are attached at spatial points so that the stretchers can be transported without twisting to support the ends of the stretchers sliding along the rope. In the described device, the sliding element is a pipe made in the form of a channel and provided with means that cover the channel. The sliding element has two ends facing upward.

The disadvantage of the prototype is that to organize the rescue of people on the building there must be two spatial points for mounting the device on the wall, in the absence of spatial mounting points, additional time is required to install them (fastening elements - pins, eye bolts) and check the strength of the fastening . This is confirmed by the exercises of the Ministry of Emergencies, conducted in St. Petersburg, which showed that for the equipment of points for hanging equipment (rescue devices, including the patent GB 536535), highly qualified specialists took two days (see the newspaper "Rescuer EMERCOM of Russia "No. 2 from January 11-20, 2006).

The task is to create a portable, quickly removable device that will allow you to mount it at the emergency site or near it, where people to be rescued, and accelerate their evacuation. The specified result is achieved by the fact that the proposed device contains elements for mounting it on a vertical wall, a portable stand and a rope with a set for lowering people fixed on it.

What is new is that it has the ability to be fixed by covering the opening or ledge of the building by forming a fastener connected to a portable rack and made in the form of a guide, in which a hook equipped with a fitting is installed with the possibility of movement relative to the rack and fixing, and on the opposite side - emphasis associated with the portable rack, and the upper part of the portable rack is rigidly connected to the plate, made with the possibility of support against the vertical part of the opening, and provided with a hole iem into which installed the rope, the number of guides, stops and hooks, and the same is at least two for each of said elements.

In another embodiment, the guide is pivotally connected to a portable stand, which is provided with an associated brace connected to the guide.

The figure 1 shows the design of the device. The device consists of a portable rack 1, a plate 2, a guide 3, a stop 4 and a hook 5, a brace 6. A hole is made in the plate 2 through which a rope 8 is laid with a set 9 fixed on it, designed to lower people. In the lower part of the portable rack 1, crossbars 10 are made that form the steps of the ladder. In the guide 3, holes 11 are made in which a latch 12 is installed, restricting the movement of the hook 5 along the guide 3. To ensure uniformity of the load when lowering people, the number of guides 3, stops 4 and hooks 5 is at least two each. The dimensions of the device should provide (figure 2): the capture of the protrusion 13 and the support of the plate 2, mounted on a portable rack 1, about the vertical part 14 of the protrusion 13. Figure 3 shows an embodiment of the device having hinges 15 and 16, which provide folding guides 3 with hooks 5 and brace 6 parallel to the portable rack 1 in order to reduce the transverse dimension during transportation of the device, as shown in figure 4.

The operation of the described device is as follows. To organize emergency descent of people in case of emergency, it is necessary to fix the device. In the proposed device, the attachment point on the protrusion 13 forms the device itself. We will explain in more detail: a stop 4 mounted on a portable stand 1 (figure 2), a guide 3 and a hook 5 form a rigid structure similar to a clamp, a clamp grip - the distance between the stop 4 and the hook 5 is determined by installing the clips 12 in the holes 11 of the guide 3. The gap between the covered protrusion 13 and the hook 5 (the emphasis 4 touches the protrusion 13) is selected by rotating the fitting 17 of the hook 5. The rotation of the fitting 17 by means of a screw pair 18 is converted into translational motion, which allows you to fix the proposed device on protrusion 13. To counter the displacement and rotation (tilt) of the proposed device in the lateral direction, it is necessary to ensure that the plate 2 touches the vertical part 14 of the protrusion 13 at least at one point 19 (figure 5).

Such a design of the device allows to simplify it and make it portable, providing quick delivery of the device and application at the emergency site for emergency rescue of people, especially if there are no previously made suspension points for such devices on the building. Arming with such a device rescue units, and simply storing them on the upper floors of tall buildings, will allow for timely evacuation of people from emergency situations, regardless of the number of storeys of buildings with minimal losses.
