DESCRIPTION

fall arrest safety device

TECHNICAL SECTOR

This application refers to a fall arrest safety device, applicable when work is done on specific points of the façade and especially in the case of possible suicide attempts.

STATE OF THE ART

It is known in the state of the art the use of inflatable mattresses that are placed below possible suicides, in such a way that they stop their fall without suffering too much damage.

A major problem with this tool is its size, which sometimes prevents its installation due to the presence of street furniture, trees, vehicles... or because they are small interior patios, sometimes with narrow stairs to access them or for other reasons. drawbacks.

There are models of mattresses for different drop heights (up to 60 meters, equivalent to a 20th floor), so they have to absorb the energy accumulated at that height. In addition, in the trajectory that the person would describe, it can hit different objects (air conditioning machines, awnings, balustrades, etc.) which can divert it or already cause damage.

It is preferable to be able to stop the falling person somewhere in the middle, before they pick up too much speed to be picked up without damage.

Likewise, it may be convenient to have an element for collecting material that falls from a construction site when work is carried out in a specific area (placement of statues).

The applicant is not aware of any device similar to the invention.

BRIEF EXPLANATION OF THE INVENTION

The invention consists of a fall arrest safety device according to the first claim and whose variants solve the problems of the state of the art.

This device is applied to elevated structures, remaining at a sufficient height so that it does not hit the ground during its operation. It comprises a support of a flexible sheet. The sheet has a rope, strap or cable (hereinafter always "rope") forming a ring around its contour that passes through both sides of the sheet alternately. This rope is free to move and is configured so that when you pull r on the rope, for example when the sheet picks up a body in free fall, the sheet slides along the rope, leaving the body enclosed in the sheet and the whole hanging from the rope. . Alternatively, a point of the rope ring can also be fixed to the sheet, for example in the area closest to the hole in the structure where it is installed, and the rope anchored to the structure. Preferably in double, so that it would cover less distance in stopping the body. The rope is fixable to a fixed point of the structure, preferably interspersing an energy dissipating device such as a shock absorber or frangible elements. It can also be fixed to several points at the same time.

The most preferred solution makes the support an inflatable structure, with a generally concave shape, arranged below the sheet, and connected to a gas source, such as a compressor or a bottle or cylinder. In this case, the coupling to the gas source can be releasable, in which case it has an automatic closing valve to prevent gas loss if released.

The inflatable protection can be in the form of a net or a mattress, but to facilitate adjustment to the person or object that falls, it preferably has a core from which a series of radial arms emerge. Can be further strengthened a first zone, either with more arms and/or wider, if it is calculated that the risk of impact through that first zone is greater.

In one embodiment, the inflatable shield is attached to a frame-engaging grip by means of a frangible attachment.

The sheet can have a concave shape, preferably deeper at the end farthest from the grip, when it is present, and the rope will also be fixed to various points of the structure or facade.

Other variants are seen in the rest of the report.

MODES OF EMBODIMENT OF THE INVENTION

Next, an embodiment of the invention is briefly described, as an illustrative and non-limiting example of the latter.

Figure 1 shows an example of an embodiment formed by a support (1,1'), in this case an inflatable protection (1), with a generally concave shape. The preferred inflatable protection (1) has a core (11) from which a series of arms (12) emerge. The arms (12) can be homogeneously distributed, but more preferably there is a first zone that is more reinforced, with more arms (12) and/or of greater width. The arms (12) They may be linked together by a membrane, a series of tapes, or smaller diameter, more flexible tubes. In Figure 1, the inflatable protection (1) has four radial arms (12), in the form of diagonals of a rectangle, and an arm (12) that is thicker in the first area.

On the concave part of the inflatable protection (1) a flexible sheet (2) is arranged, generally formed by a canvas or net, sufficiently resistant so that it does not break when the person falls or due to friction with sharp elements that it may carry. on clothing, tools or other objects falling parallel.

The flexible sheet (2) has around it a rope (3), strap or cable that passes through holes, net or mesh passages, eyelets... so that it passes through both sides of the flexible sheet (2) in a alternate. The rope (3) is free to slide along the contour of the flexible sheet (2), so that when picking up a body in free fall, the sheet (2) slides along the rope (3) and is strangled by it in its top.

The inflatable protection (1) is connected to a source of pressurized gas (4), generally a bottle of compressed air. In this way it is possible to fill it at high speed when it is necessary to deploy the device. The connection of the gas source (4) to the inflatable protection (1) is preferably releasable and breakable (so that in the event of the body falling before uncoupling the air bottle, it is not dragged by the device) leaving a valve self-closing valve on the side of the inflatable protection (1), such as a one-way valve. Thus, if both elements are released, the gas inside the inflatable protection (1) is not lost since the automatic closing valve stops the leak.

The inflatable protection (1) is coupled to the sheet (2) by at least one point, so that they cannot be separated. The most preferred way is through a point in the core (11) of the inflatable protection (1). It can also be fixed at various points on both perimeters.

The sheet (2) can be substantially flat, but preferably also has a concave shape, so that it follows the interior of the inflatable protection (1).

The inflatable protection (1) has a frangible attachment (5) to a point on the façade, such as a grip (6) attachable to a window. This grip (6) must be fixed to the facade in a way that is strong enough to support the entire device through the frangible fixing (5), prior to the fall of the person or object.

On the other hand, the rope (3) must be fixed in a resistant way to the facade or another solid element, preferably to a resistant element crossed obliquely in a lower corner of the window, in order to be able to support the weight of the device for a person who has fallen, even resisting the pull when breaking the fall, through the rope. This fastening of the rope (3) can be in the grip (6), for simplicity, inserting an energy dissipator or shock absorber.

The rope (3) can also be fixed at various points, so that the fall of the device is more controlled and it can be braked more quickly.

In one embodiment, the frangible fastening (5) incorporates the rope (3), so that it is the rope (3) that breaks the frangible fastening (5). For example, the rope (3) can pull on a flap or a pin when it moves due to the effect of an object or person falling on the sheet (2) and its closure. Removing the flap or pin breaks the frangible attachment (5).

In use, the inflatable protection (1) is arranged at the point to be protected, below a possible suicide or risk situation. As it is handled deflated, it can be easily handled and passed through windows or doors. Once located, the grip (6) and the rope (3) are fixed to resistant points. The inflatable protection (1) is inflated, so that the sheet (2) unfolds and tightens, placing it in position. If a person falls, it is picked up by the sheet (2) and pushes the inflatable protection (1) downwards. This push disengages the frangible fastener (5) and the assembly descends closing the sheet (2) by sliding along the rope (3) which is fixed to prevent the object or person from escaping. Everything hangs from the rope (3), while the inflatable protection (1) protects the person against knocks against the facade and other elements. The area in contact with the façade will be the "first area" of the inflatable protection (1), under the grip (6). The device can be installed at a height, away from the ground, so that the person has not reached too much speed and the protection is more effective.

The use of this tool is conceived in the context of intervention by firefighters: firefighters install it In the event of picking up a victim in the device, firefighters can lower the assembly with other tools they already have or even hang down from the façade to the victim to proceed to his rescue.

In one embodiment, the sheet (2) is in the shape of a prism, but with non-parallel bases. The lower base would be oblique, with the highest part at the end opposite the grip (6) (figure 1). This allows the person to be picked up more quickly and to be able to cut the necessary distance to function.

In one embodiment, the grip (6) of the inflatable protection (1) with the frangible attachment (5) is eliminated and replaced by a weak grip (6') as a ballast or even a series of handles to be held by the user, since it only performs the function of retaining the device prior to the fall. On the other hand, the rope (3) always needs to be solidly supported. In this system, the support (1,1') may not be an inflatable protection (1), to be lighter and more portable, but rather a frame (1') that carries the sheet (2) in a detachable manner. In any case, the sheet (2) could be padded.

The rope (3) can have an energy absorption system, such as a shock absorber, a series of breakable retaining elements... so that the braking of the device is more gradual.
