Rescue device for evacuating people from high-altitude objects

The utility model relates to devices for evacuating people from high-rise buildings, including from high-rise buildings, during emergency situations (fire, earthquake, terrorist attack, etc.), when it is impossible to use an elevator or staircase.

A rescue device is known (US patent No. 4582166, class A 62 B 1/20, publ. 1986), used in a fire. It includes a mesh sleeve laid on the trolley with end rings (input, mounted on the trolley, and output equipped with a carabiner) and a cushion, as well as a guide wire device. The latter consists of a wire (cable) installed obliquely and fixed with the upper end at the upper part of the window opening, and the lower end - at the anchor (anchor arcuate beam, the ends of which are fixed in a concrete base). In case of fire, the sleeve is thrown out through the window opening, having previously laid a cushion on the windowsill and hooked

a carabiner associated with the lower ring of the sleeve, for the wire guide device. A disadvantage of the known rescue device is that the horizontal distance of the anchor from the wall of the building (to ensure safety by reducing the speed of descent) increases with the height of the building and can reach a size that cannot always be ensured.

° ° A 62 in 1/20 Rescue device is also known (US patent No. 6098747, cl.

A 62 V 1/20, publ. 2000), fixed outside the window opening. It includes a bracket and a mesh p) av made of such a weave that is inextensible in the longitudinal direction and extensible in the transverse, which ensures safe (due to contour crimping) descent of people with a vertical orientation of the p-cantilever. The disadvantage of this known device is the lack of means for returning the sleeve to its original position after use, which creates an inconvenience in operation.

A rescue device is also known (Japanese application No. 60-56501, class A 62 B 1/20, publ. 1985). It includes a container mounted on the roof of the building in the form of a box for storing rescue equipment of an elastic sleeve with a bottom (bag with side exit). The box has a horizontal support frame and a flat element pivotally connected to it and having a horizontal axis of rotation to close the opening π1; ika. A truss expanding into the console is pivotally connected to the frame; it contains a deck of articulated interconnected elements and two side walls of articulated tubes and extensions. The sleeve is fixed to the outer end member of the flooring. The device is equipped with a means for extending the sleeve, which is made in the form of a manual winch with a lifting cable, passed through a horizontal cantilever tube and then guiding it: I cover it and connected with an annular hanging element, it holds the sleeve at its bottom part. The axis of the winch drum is open; it is parallel to the axis of rotation of the element to close the opening.

2 The capacity of the drum (its axial dimension) is determined by the required length

cable, i.e. the height of the building. The disadvantage of this known device, adopted as a prototype of the proposed utility model, is that it is necessary to stretch the sleeve after raising its front to the floor level and further responsible manual work on it sweet for re-emergency use.

The objective of the proposed utility model was to create such a rescue device for evacuation; approach from high-altitude objects, which, while maintaining the safety of lowering people and ease of installation, ensured that the sleeve was laid after using it in one lifting operation.

To solve the problem with achieving the specified result, the rescue device for evacuating people from high-altitude objects contains an elastic sleeve, for example, with a bottom part and at least one side exit, a frame articulated to it and having a horizontal axis of rotation, a flat element for closing the container opening for storage of a sleeve, a winch mounted on the frame, for example with a manual drive, the axis of rotation of the drum of which is parallel to the axis of rotation of the element to close the opening, and the cable is connected to the exit th sleeve end. A distinctive feature of the proposed device is that the frame is located vertically, its lower part is made with an opening for the passage of the sleeve and people, the upper part of the sleeve has a cutout in its side surface from the opening, is attached to

,,

3 lower inner side surfaces of the frame and to the inner

the surface of the element to close the opening, expanded within the element to close the opening and mated with the middle part of the sleeve with the possibility of folding the width to half the size of the outer perimeter of the middle part of the sleeve, winch size; inside the upper closed part of the frame, with the opening width and working length drum winch made more than half the size of the outer perimeter of the middle part of the sleeve.

To prevent injuries to people during their descent, the element for closing the opening is equipped with a lining of elastic material with its placement on its inner side.

one upper horizontal 17 and rear upper vertical 18, which forms a container 19 for storing the sleeve 1. The frame 2 is equipped with a flat element 20 for closing the opening 13 of the container 19. The flat element 20 with two hinges 21 with an axis of rotation 22 with a lower location at the threshold 23 aperture 13. The width Bp of the aperture 13 must satisfy the condition 57uD, where D is the outer diameter of the middle part 5 of the sleeve 1.

The tool 3 for lowering and returning the sleeve 1 is made in the form of a winch placed inside the frame 2 in the area of its upper part 14. The axis 24 of rotation of the drum 25 of the winch 3 is parallel to the axis of rotation 22 of the element 20. The length Wb of the working part of the drum 25 must satisfy the same condition as the width of the cn of the opening 13. The axis 24 of the drum 25 is located in the bearings 26 located on the side walls 15 and 16. The lifting cable 27 of the drum 25 is connected to the end part 6 of the sleeve with the 1st bottom ring 28. Winch 3 is equipped with a belt brake 29 brake band 30 which covers ormoznoy drum 31 and is kinematically coupled with L-shaped control lever 32 and its pivot axis 33, respectively. The winch 3 also has guide axes 34 and 35 and a shaft 36 mounted parallel to the axis 24 of the drum 25. A ratchet wheel 37 is fixed on the axis 24, which interacts with the pivoting dog 39 on the axis 38. At the end of the axis 24 there is a square 40 for connection with the removable handle 41 .

The front (upper) part 4 of the sleeve 1 has a cutout 42 in its lateral surface from the side of the opening 13, is attached with screws 43 to the lower inner surface 44 of the frame 2 and the inner surface 45 6

element 20 for closing the opening 13, which can be equipped with a lining 46 of resilient material, such as foam polyurethane (Fig. 8). The upper part 4 of the sleeve of IpacninpeHa is within element 20 and mates with the middle part 5 of sleeve 1, and this is done by insert 47 (Fig. 7), and the open contour of the abode of part 4 is represented by two figures - the rectangle abed and the triangle ade. The insert 47 is sewn to the middle part 4 of the sleeve 1 and provides the necessary inlet section and the possibility of folding up to a width of 0.5 l; O (i.e., up to the size of a half-perimeter of the middle part 5 of the sleeve having an outer diameter D) after using the device, with points a and d, b and c are in contact.

For ease of access to the winch drive 3, the frame 2 can be equipped with an L-shaped shield 48 with a vertical axis of rotation 49. To hold the element 20 after closing the opening 13 in the upper position, the frame 2 has a rotary holder 50 with a horizontal axis 51.

Below the opening 13 can be installed with the possibility of interaction with the element 20 of the damper-limiter 52 made of rubber, and on top of the threshold 23 - rotary shaper 53 with an arched middle section to ensure a constant input section of the sleeve 1.

The operation of the proposed device is easiest to illustrate with a sleeve 2 equipped with a brake 10 when installing the device on the balcony 54 of a multi-storey building 55 with the frame 2 secured with dowels 56. In the initial position, the cable 27 and the protective sleeve 1 together with the brake sleeve 27 are on the drum 25 winch 3. In 1 extreme situation, by turning the holder 50, the element 20 is released and,

pushing it out, open the opening 13 (Fig. 11). Under the influence of the weight of the element 20 and the weight of the part of the sleeve 1 attached to it, the drum 25 begins to rotate and the sleeves 1 and 10 fall. The speed of their lowering is regulated using the band brake 29 by pressing the lever 32, and the opening 13 is subsequently opened completely (Fig. 12), the sleeves 1 and 10 are completely unwound from the drum 25 (Fig. 13), then lowering them on the cable 27 until they hang above the ground when the bottom reaches the design hover, determined by the size, 8 ... lM (Fig. 1 ) After pushing the upper part 4 of the sleeve 1 forward and turning the former 53 into the working position, the device is ready to evacuate people. The braking of each saved is due to the contour compression of the brake sleeve 10, followed by leaving the sleeve 1 through the outputs 8.

After using the device, the lifting of the sleeves 1 and 10 is carried out in the reverse sequence (Fig. 14 ... 17). Using the handle 41 rotate the drum 25, turning the dog 39 into engagement with the ratchet wheel.

The proposed utility model expands the range of life-saving appliances with an increase in their functionality.
