Description

Technical field

The utility model relates to personal protective equipment, in particular, to save people in case of fire in multi-storey buildings.

State of the art

Analogs to the applicant are not known.

It is widely known that during a fire in multi-storey buildings that are engulfed in fire, in most cases people jump out of windows because they are unable to get out of the room. Such a decision will lead to the death of people or result in bodily harm, for example, various fractures, bruises, etc., which, thus, will lead to disability of people.

Based on this, a compact device was developed to solve this problem.

Utility Model Disclosure

The objective of the claimed utility model is to develop a reliable device that provides safe descent from multi-story buildings in case of emergency or emergency.

The technical result is a more stable stabilization of the decline.

The technical result of the claimed utility model is achieved due to the fact that the umbrella parachute includes a rod, a dome made of fabric, slings, while the edge of the fabric part of the dome contains an additional reinforced layer with elements for attaching one end of each line, the rod contains an opening / closing mechanism, the supporting spokes of the dome frame and the handle, in addition, an annular connecting element is fixed to the rod for attaching the other end of the said slings.

The handle further comprises a safety element.

Utility Model Implementation

Parachute umbrella is made on the principle of a folding umbrella machine.

A parachute umbrella consists of a rod (1), a dome (2) and a sling (14). The dome (2) is fixed in the upper part of the stem (1), which has a tip (3). The lower part of the rod includes a handle (8), over which an annular connecting element (13) is located for fastening one of the ends of each sling. The handle (8) contains an open / close button (12), which directly relates to the opening mechanism (9). The handle contains an additional safety element, which is a loop with a latch (15). Supporting spokes (14) are installed on the upper part of the stem with the ability to maintain the dome frame.

The rod (1) can be made telescopic multifaceted or round. The number of rod elbows does not exceed 6 pcs. Each knee does not exceed 60 cm.

The opening / closing mechanism (9) fully complies with the principle of an automatic umbrella, which is located inside the stem (1) and is a rigid spring with a slider. A sliding sleeve is located on the stem, on which supporting spokes (10) are pivotally mounted. The opening / closing mechanism (9) is interconnected with a sliding sleeve. The supporting spokes (10) are connected to the supporting frame of the dome.

The opening / closing mechanism (9) of the parachute umbrella is set in motion by pressing the button (12) located on the handle (8).

The handle (8) is made of rubberized material.

The tip of the stem (3) serves as a fixed connection of the stem (1) with the dome frame (2).

Each tip of the knitting needle (7) performs the function of securely fixing the fabric of the dome (2).

Each link of the knitting needle works to open / close the parachute through a swivel.

The dome (2) is additionally fixed with a nylon thread to each knee of the knitting needle (4, 5, 6).

The dome (2) consists of a supporting frame and a cloth part. The frame is a set of metal links (folding knees), in the form of knitting needles (4, 5, 6), in the upper part of which the cloth part is fixed. The dome (2) is made in the form of a hemisphere. The edge of the fabric part of the dome contains a reinforcing element (16), which is superimposed on the fabric part and stitched together with the fabric part of the dome. The reinforcing element (16) is an additional fabric layer with increased strength, for example, a tape made of nylon and / or nylon, etc. The edge of the dome contains connecting elements for fixing one of the ends of each sling. The connecting element can be made in the form of holes located at a distance of 10 cm from each other. At the top of the dome (2) contains pole holes to stabilize the decline, located at a distance of 6 cm from the tip of the dome. The edge of the holes is treated with kapron tape.

Each sling (14) is made in the form of a nylon cord and / or cable.

Line length up to 4 m, number up to 12 pcs.

The calculation of the load of the canopy of the parachute is made according to the formula:

Total weight in equipment / area of the canopy;

D = P _floor / S.

According to international standards, the weight of the parachutist in equipment is expressed in pounds, and the area of the parachute in square feet.

Convert from weight in kilograms to weight in pounds:

Weight in kg / 0.453;

P _floor = P _(kg) / 0.453.

Convert dome area from square meters to square feet:

Area in m ² / 0.093025;

S = S (m ² ) / 0.093025.

Further, the result obtained is compared with the data below.

Loading 0.9 - 1.3: Safe loading, recommended by manufacturers, allows you to land on fairly limited areas without problems and not have problems when landing in calm.

Loading 1, 3 - 1.5: The dome becomes more energetic in performing maneuvers, but remains safe enough. When landing in calm, if the dome is not specially dispersed, you have to run a few steps.

The table shows examples of calculating the radius of the canopy of a parachute umbrella for different person weights.

Person's weight Umbrella radius Dome Area Loading Up to 60 kg = 132.45 pounds 1.75 m 9.6 sq. m = 103.4 sq. feet 1.28 Up to 90 kg = 199 pounds 2.15 m 14.5 square meters m = 156 sq. feet 1.28 Up to 120 kg = 265 pounds 2,50 m 19.6 square meters m = 210 sq. feet 1.26
