Abstract

PURPOSE: To realize a safety tool easily usable for going down to the ground from an altitude, by equipping a belt means and a cable winding/unwinding means bearable to draw down the weight of a human body and a rucksack during falling down and a control means to perform unwind control. CONSTITUTION: This rucksack comprises a box shaped rucksack with a back front part 15 padded for supporting by a back and has a belt means to safely tie to the back of a jumping down person. A cable winding/unwinding reel 3 is equipped in the box shape. Cables 2, 2' made of copper or nylon are guided from a winding frame 8 on a winding rod 9 by the winding and unwinding reel and guided outside by a cable guide 10 provided with a seal 11 to control tension in use. The resistance in unwinding the reel 3 is controlled from pressure of a spring 4 increased or decreased by a fitting metal 14 with resistant friction and a shaft 13 is key-bonded to a coil reel 3 by keys 3', 3".

Description

[Detailed description of the invention] [Field of invention] The present invention relates to a fall prevention rucksack.

This improvement is particularly useful as a means of safely lowering a person trapped in a burning building from a height where jumping would result in a fatal fall.

[Background of the invention]

This type of safety device is not known in the prior art.

[Problem to be solved by the invention]

The object of the invention is to provide an easy-to-use and practical safety device for descending to earth from a height in a safe manner without the aid of a ladder or a parachute.

[Means and effects for solving the problems] These objects have the features claimed in the claims of the present invention,
This is achieved by means of anti-fall backpacks, which have the ability to secure the backpack to the person, wipe during the fall to stop the fall, and each decelerate, pulling the weight of the human body and the backpack. A belt means capable of withstanding lowering and a hook means at the end of the cable are provided, each having a deceleration during falling to stop the fall, and capable of pulling down the weight of the human body and the rucksack. cable winding/unwinding means capable of withstanding the same; and braking means for controlling the unwinding of said cable during a fall.

In such a way we obtain a safe advantage of ensuring a controlled fall from a certain height without causing damage to the person descending himself.

Advantageously, said braking means for controlling the unwinding of said cable comprises adjustable unwinding resistance means.

Equally advantageously, the braking means are manually operated and controlled by the handle branch means.

In this way, the operator can adjust the fall speed in relation to the specific weight.

Advantageously, the braking means are associated with an adjustable spring-controlled deceleration means.

In this way, even without braking action, some unraveling resistance will reduce the fall speed.

Hooking the fall arrester (shaped like a case) on the back through a self-tightening belt (such as a car safety belt), and hooking the free end of the cable to a part of the building. By hooking, a person can, for example, jump to avoid a fire hazard.

The height of the jump is limited by the length of the cable.

The winding/unwinding device allows for controlled fall.

As mentioned above, the fall prevention backpack backpack is (
(during jump) is provided with a compensating spring that reduces wrench unraveling and reduces cable tension. After stretching to the maximum, the spring releases the last "band" (
In such a way, the cable is continuously controlled by the spring.

The tip of the cable has a gun-shaped hook for quick hooking on buildings.

The weight of the load (or person) that a fall prevention rucksack can allow to be lowered can be adjusted to achieve variable strength (
(discontinuously) is limited by the tension of the spring, which is adjusted by varying its filling, which is stacked in steps. Therefore, the anti-drop backpack is tared as a sandal in a person's weight and utilizes a manual brake to increase its strength. In the case of free fall (because the spring is loaded for lower weight) this will get into the groove too quickly.

These and other advantages are apparent from the following description of the preferred solution together with the drawings, the details of which are not to be considered limiting, but are merely illustrative.

〔Example〕

With reference to the drawings, a box-shaped rucksack (1) with a padded back part (15) for back support
and has belt means (not shown) for securely attaching it to the jumper's back. Inside the box shape (including the device in the rucksack shape) a cable winding/unwinding reel (3) is provided, in which the cable (2, 2') made of steel or nylon is wound on a winding rod (9). From the frame (8) it is guided to its unwinding and winding reel and guided to the outside by a cable guide (10) with a seal (11) that controls the tension in use.

The unwinding resistance (speed) of the reel (3) is determined by the shaft (1
Regarding 3), fillers (1
4), the shaft is keyed to the coil reel (3) with keys (3°, 3°).

Obviously, the pressure in the coil spring can be applied to the coil spring by means of other means, such as by threading the support shaft and making use of a rotatable ferrule, causing compression of the spring by means of external manual adjustment. By using internal fillers (in the drawings), more variations can be made.

The figure further discloses that the brake set is secured from a Boo'J (5') keyed to the wind-unwind reel. The brake is realized by a one-sided belt (5) stretched from a double lever (7-7'') via a respective pair of connecting rods.

The double lever (7) extends forward on the side of the person to whom the anti-fall backpack is fixed and is articulated by a cross bar (7゛) that serves as a lowering handle for adjusting the brake. It is also used as a safety measure to grab onto in the event of a fall.

That way, during the fall the operator remains held himself on said lever and acts to pull it (strongly) due to the instinctive reaction at the main speed during the fall. Will.

In this way, an automatic control for the instinctive reaction of the operator is determined.
