Description

The invention relates to a means of saving people from tall buildings.

Similar devices are known, for example, Russian patents No. 2200813, 2319525, 2435620 (prototype). The first two devices are stairs of various designs, and the last is a cable conveyor for lowering people from a height. However, they all have two significant drawbacks - they are limited in mobility and expensive.

The objective and technical result of the invention is to increase the mobility of the rescue device and reduce its cost.

OPTION 1. For this, the device is light and small, mounted on a motorcycle, which can get much faster through traffic jams to the place of fire, and can also drive to any place in the building, entrances to which are often forced by cars. This variant of the device is a firing device and a fired “anchor-cat”, on the armature shaft there is a ring with an eye, and one more eye is in the front part of the armature, and a flexible cable is attached to them so that the ring cannot come off the shaft, moreover the cable is wound around the end drum (like a spool on an inertia-free spinning reel), and it is possible to install a mobile device on the cable.

Something like a 12-gauge hunting rifle with thickened barrel walls mounted on an arm on a vehicle (on a motorcycle) or on a tripod and equipped with an optical sight can be used as a shooting device. Mounting on a motorcycle or on a tripod is necessary because the recoil may be too strong for shooting from the shoulder. In addition, the aiming accuracy is higher.

So that when shooting at the window, the cat-anchor (hereinafter referred to as the "anchor") does not bounce from the window frame or frame, its paws should have an angle of no more than 45 degrees with its rod. In this case, when touching the frame, the anchor will still fly into the window.

To prevent the ring on the anchor rod from moving back to the front of the anchor, the rod has a spring-loaded latch that does not protrude beyond the diameter of the rod (so as not to interfere with the anchor being inserted into the barrel).

An anchor for this embodiment is shown in FIG. 1, where 1 is the shaft, 2 - legs (4 or 5 pieces), 3 - the ring with the eye on the shaft, 4 cable is better from aramid fiber, for example, from Vectran (it is more durable and heat-resistant). When shooting through a window in which there are already flames, the upper part of the cable can be replaced by a chain made of heat-resistant steel. An anchor should be made of the same steel.

This device works like this: a crew of two rides a motorcycle to a place where you want to save people from the windows, or from the balcony, or from the roof of the building. The motorcycle is placed on the bandwagon, and in the design of the motorcycle it is desirable to provide two widely extendable rear steps. An anchor is fired from a bracket mounted on a motorcycle. Moreover, in the position inserted into the trunk, the ring at the anchor moves as close to the paws as possible (so that the armature rod goes deep into the trunk).

When fired, the anchor flies out of the barrel of the firing device, the ring under the action of inertia and traction of the cable moves to the rear end of the anchor, snaps into place, and the flying anchor turns the cable from the end drum in turns. An anchor flies into a window located above that window from which it is necessary to save people (if possible). If the window is on the top floor, then the anchor is cast onto the roof.

Then, a mobile device consisting of a box is installed on the cable, in which under the opening cover there are 4 or more rubberized pulleys connected by a common drive chain to a gear-motor, and one or two rescue grips for a person’s hand are attached to the body according to US Pat. Russia No. 2643084.

In order for the rollers to have sufficient friction with the cable, its lower end must be pulled a little, or the mobile device must have a spring-loaded roller, pressing the cable to the rubberized pulley lower along the cable.

In FIG. 3 shows this device, in box 5 there are four rubberized pulleys 6, all rotated together by one chain (not shown, maybe from the Zhiguli engine), the pulley lower along the cable has a spring-loaded pinch roller 7 (shown conditionally). One of the rollers is rotated by a gear-motor 8, designed on the verge of self-braking. A flexible cable 9 is wrapped around the pulleys.

After the anchor is fired, the cable is inserted through the hinged lid of the box and the lid is closed.

An electric cable 10 is suitable for the box, and two hand grips according to US Pat. Russia No. 2643084 (not shown).

The mobile device works as follows: it is put on the cable and rises slightly to the level of the desired window due to the operation of the electric motor 8 along the cable slightly stretched from below. One or two people take on the rescue hold, and the electric motor turns on in the opposite direction. People smoothly fall to the ground. Then the mobile device will again rise for the next people.

OPTION 2. From the firing device it is not easy to get into the window located on the 14th floor and above. Corrections are required for the range, the angle of inclination (the motorcycle should drive up so that the aiming angle is always about 60 degrees to the horizon), the wind, and even the temperature of the powder charge. And starting from the 20th floor it is almost impossible. Therefore, the anchor can be shot into the window from a radio-controlled copter equipped with a weakened firing device.

Otherwise, this option is similar to option 1 and works the same way: the copter raises to the desired window, and slightly shoots the anchor at it.

OPTION 3. The copter may not shoot the anchor through the window, but bring millet, but for this it should have a special form of several screws in the rings - several screws, each of which has a diameter smaller than the glass of the window, are arranged in a row, on one side there are two screws across this row, and at the other end there is a point equipped with a carbide tip.

To compensate for the reactive moments of the screws, there should always be an even number of them.

To protect against damage to the screws by glass fragments, the screws of the copter can be closed on top and / or bottom with strong nets or blinds.

This copter is shown in figure 2. It has four screws 12 in the rings located in a line, and two more screws 13 in the rings located at one end across this line. Due to the transverse screws, redistributing their thrust, the copter can be controlled along the roll sideways from the mentioned line. And due to the redistribution of thrust between the conditionally front (where the tip is 14) and conditionally the penultimate (before the two transverse) propellers, the copter can be controlled by pitch.

The copter works like this: it rises to the desired window, breaks it with a tip with acceleration, and flies into the transverse rings of the screws all the way. An anchor fixed in the center of gravity of the copter with a controlled mount is dropped and hooks on the windowsill. At the same time, the copter eases sharply, and can rise sharply, hit the window slope, and be damaged. To avoid this, the control system of the aircraft must, after dropping the anchor, automatically correct the lift, reducing it to the necessary degree.

Note: the formula does not contain a limiting part, since the invention has no relevant analogues. This type of formula is allowed by the Rules.
