HELICAL RAMP LIFE-PRESERVER

Abstract: The present invention patent of "HELICAL RAMP LIFE-PRESERVER" refers to one or two helical ramps (Fig. 1 and 9), supported by the metallic structure, fixed on the building and supported soil by two pillars (Fig. 2 and 4), supported on blocks, that leans on stakes (if necessary), having as access, ramps (Fig. 1, 2, 3, 4) that links both catwalks (Fig 4-4), which make part of the BUILDING (Fig. 5, 6, 8, 9), that are fed by the cuts fire doors (Fig. 4-6), that allow the access to the catwalks or platforms of embarks (Fig. 4-4), protected by metal body protector (Fig. 3, 4) and its structure in concrete or metallic (Fig. 3, 4, 8, 9), defined by independent pillars, metallic semi-arches supports and flagstones into the body of the Building in subject. The helical ramps (Fig. 1, 5, 6, 8, 9), get down around the pillars, in straight and curved pieces (Fig. 1, 2, 3, 4, 5, 8, 9), allowing the agreement of the small spaces of the ramp, (Fig. 2, 3 and 4) which links the catwalks (Fig. 3, 4) to the main helical ramps (Fig. 3), allowing to watch another users' passages, seeking with this to avoid shocks or running over, in such a way to organize the going down. The water that runs through the tubes, irrigates the ramps (Fig. 6 items 1 and 2), then people who go down can and reach the pool (Fig. 5) placed in the quota determined by the building, being the water coming of the boxes (Fig. 6), placed on the top of the building. The pool should be placed on the point chosen to the final and exit of emergency of the Building eventually on disastrous. The ramps should have bars of protection like balustrade along its course, alike avoiding falls or sliding bodies outside. When there are not blind walls, there must be extended automatically a curtain of amianthus cement from the top to the bottom of the building, being viable its use and object of complement of this invention.

Description: " HELICAL RAMP LIFE-PRESERVER " The present Patent of invention refers to a model of helical ramp, destined to the collective use, for immediate rescue of lives subject to probable fires, and for them to be used in buildings of any height, or places that cannot be reached by the devices in use nowadays, such as the " Magirus " stairs, or even to those where these can reach although the eventual delay to help, would put in risk people's life in eventual emergency state It happens that in most of the fires, the probable delay on firemen's arrival, not because of them, but in because of the traffic or other difficulties, or the distance to the place, or even because we need more appropriate equipment and for that the budgets are usually litles facts that compete to the rescue statistics in fires of great load, be unfavorable for us or because the stairways in closed spaces had as instrument adapted to the rescue can occasionally (In Brazil) be transformed in a snare and in a chimney, because only one door is enough (even having a room before) forgotten open, the smoke will penetrate through it and going down will become impracticable, because of the lack of oxygen and consequent immobility to the normal people Without considering people who have any physical deficiency, old people and also children, or even estimate animals (these don't count with a minimum possibility in the current, because deficient people don't go down on stairs') Related to the fire extinguishers, whose maintenance many times it is precarious they compete to some cases, in the moment of larger need, stop working and also per times, for they being inadequate to the fire type, because there are cases which the extinguisher is inadequate We believed that talking about lives human beings, or any kind of beings deserve our special attention to these facts 1 This invention intends to assist to any type of immediate rescue, filling this emptiness To better understand this patent is attached the following drawings FIGURE 1 with the perspective of the building with two ramps FIGURE 2 with the perspective of the two ramps and detail of sections, FIGURE 3 with the perspective of the building with one ramp and detail of the access FIGURE 4 with the perspective of the building with two ramps and detail of the structure FIGURE 5 with the perspective of the building with two ramps and detail of the arrival at ground, FIGURE 6 with the perspective of the building with two ramps and detail of water tubes and boxes of water FIGURA 7 with details of water tube and helical ramp, FIGURA 8 with the perspective of the building with one ramp with detail of acesses and FIGURA 9 with the perspective of the building with one ramp On Figure 1 , there is the building, that should have wall without windows (when there is not it is foreseen the going down of a curtain of amianthus cement) with cut-fire doors exits (Fig 4 - item 6) on each pavement that allows the access to the catwalks (Fig 4 detail 4) which can be armed or metallic flagstones or still in any incombustible material being in swinging provided of enough space to shelter the habitants of one or more pavements (besides the floating population of the building), because each pavement will have its catwalk provided with safe balustrades (see details on Fig 3 and Fig 4), preferably on the side of the building where windows don't exist, because we should try to avoid that the smoke or the fire, reach this part, which is destined exclusively to the rescue (could be common to two buildings) Being like this, people in danger would run to the cut-fire doors (fig 4 item 6) and consequently to the catwalks (Fig 4 item 4), and through them, they would have access to the ramp by an access ramp, witch establishes the connection among the catwalk (Fig 2-ιtem 2, Fig 3 - item 1 and Fig 4 - item 3) and the " helical ramp life-preserver", whose inclination, was and it will be calculated in function of the distance between pavements and with enough inclination to allow to slide without problems, to the users and even to objects, or animals to which are intended to save, (it works as a rescue exit, see details of the ramp on Fig 5 - exit and final det 1 ), having certainly as priority the human lives and the life of estimate animals the ones which for the children, have fundamental importance on its lives On this way with this use, we intended to assist to a quite including strip, with the evidenced application plain for the purpose of the use The RESCUE OF THE LARGEST NUMBER OF PEOPLE Possible' This fact is evident, because of the easiness and speed of going down (48 people per minute), as the easy access, as the short maintenance demanded by the group (Fig 1 ), besides the minimum cost, because it doesn't have mobile pieces and have little waste, just like our other patented invention some time ago (I refer the Stairway roll down lifeguard ) On the inferior part, the exit, we will have a ramp whose declivity at the end, allows the reduction of the speed and at the end of this ramp, denominated of exit (Fig 5 - it details 1 ), built in flexible material (could be glass fiber, since it is been mixed to the amianthus cement and turned to incombustible, or even of steel), a box of sand or water is foreseen (Fig 5 - detail 2), that it propitiates space to avoid people's accumulation, objects or animals in the end of the ramp, in such a way to avoid obstruction, or to cause damages in any of those elements With everything established, they will be saved' - at least this is our objective Alike of decreasing the attrict between the body and possible burns in the backs, legs and arms, due to the abrupt slide, the ramp will be wet by a controlled jet (Fig 6 and Fig 7 detail) for the own opening of the cut-fire doors which will be possible, because of the existence of two complementary boxes of water (Fig 6 - Det 1 ) and destined exclusively to this use They will be located on the top of the helical stair and dimensioned for this purpose, based on the population of the building, sheet of water is necessary and with speed and calculation flown down, in function of the height and traverse section of the ramp, that can be under the form of an " U " (Fig 8 general and detail) or semi rectangular section, or still tubular, depending on the local needs and of safety requested in its employment The materials employed on the " helical ramp life-preserver " (Fig 1 and 9), can be from metal acrylic polish-carbonate or other material compatible with the safety and stability requested by the objective that is intended Should assist the condition of priority of rescue functional, aesthetics and the laws of safety of the local firemen and proceedings of assembly of the condominiums the ones which with the code of postures of the municipal district they should be adapted to these purposes The measures for its utilization will be due to the conscience of the organs of government and controllers investors and habitants with its private interests which I hope will go back to the rescue of human lives including on this, the interest of the insurance companies that will surely save a lot when supporting this invention "HELICAL RAMP LIFE-PRESERVER", requested for the rescue of lives in cases of fire in metal, or any other incombustible material not subject to deformation because of the heat It should assist the going down of people, through the inclination angle among the pavements, as well as to allow the access through concrete or metallic catwalks, protected by body protectors, along its course The ramp is sustained by a metallic structure or in concrete pillars or metal structures (Fig 2 - see detail on the numbers 1 ,2,3 on the right top of the figure), in half rings into the central pillars, and on the own wall of the building (details on Fig 4, n° 1 ), or on its structure, although it leans independently in function of the pillars, in concrete or metallic, which sustain and define them by the helixes that surround them and go down until the pavement where the mirror of water or pool is placed (Fig 5, under n° 1 - the detail) The pool allows extinguishing and to moisten the bodies in eventual combustion, seeking to turn off these effects and to soften the going down and to aid the bodies on its final stop Could be accessed by any human being, faulty or not as well as to serve to the estimate animals and objects The ramp is irrigated by the boxes of water placed on the top of the building (Fig 6 - detail n° 1 ), provisioned by a system of bombs with independent own generator, or through solar system of energy, or just batteries (optional) The helical ramp life preserver, are constituted of straight and curved modules (Fig 2 - items 2 and 3 on the detail), adapted to the necessary inclination to the descense, as well as modules of access and middlemen (Fig 3 - ιtem-1 ) between the catwalks (Fig 3 - item 2 and Fig 4 item 4), that allows the access to the cut fire doors (Fig 4 - item 6) placed preferably on the blind part of the Building (Fig 4 - item 5) These ramps are to the flowage of the water by the gravity already mentioned on the text from the boxes of water placed on the top of the Building (Fig 6-ιtem 1 ), whose tubes travel the whole ramp, with worked irrigation by opening any of the cut fire doors could be controlled by solar system or battery, being the irrigation with purpose of decreasing the attπct between the body that goes down on the ramp wetting its clothes (or the body) and decreasing the heat provoked by the fire and by the attπct when couple, the ramps allow larger safety, avoiding running over and collisions among the individuals, with larger flow of traffic, it decreases the time of flowage of the building and of its floating or permanent population It was calculated to a Building of 20 pavements (60,00 m of height), with medium area of 500 m2 It was considered 1 person at each 25 m2, being 20 people on each pavement, multiplied to put 20 pavements, results on 400 people with 20% floating (Building of apartments), they would result 2m 480 people they to be she you save The esteemed time of 60m to 12 m/s (admitted Speed of flowing out) it would be of 5 seconds without intervals (60/12 =5) As the ramp has enough space for 2 people to go down at the same time, (or 4 people when couple), to each interval of 1 second 4 people could go down that would take 5 seconds to go down If we divide 480/4 and we multiply to 5 we have the total of second expenses for the flowing down of the building and of its population that is of 600 seconds or 10 minutes Therefore the whole building would be safe in 10 minutes (In a rudimentary calculation subjected to alterations on practice with time measured on a chronometer and also in function of appropriate training, time to wait, etc., as it is made for the elevators)
