The issues of a person with reduced mobility, especially those of our elders, are known when it comes time to leave the house. The dilemma is: should I leave my home more than one floor because of the risk of falling down my stairs to live in a retirement home with high annual fees? Mechanical systems exist to answer this dilemma but they are expensive. We only have to think of chair lift escalators. However, these systems are not versatile when it comes time to install them. Moreover, many older people are denied such an installation because of a staircase too narrow for example. Even if the installation of these expensive chairlifts is carried out, 11 remains a non-negligible condition to be considered for the user but also for the Society and the public health: the use of a staircase in a safe and daily way is a undeniable advantage for cardiovascular health! The present invention is a compromise to all these aspects. The precise dimensions of a staircase or stairs are measured and there is installed a secure suspension system by a rescue type jacket, but stylized (see drawings subject to the present invention SKY HELPER). The user puts the jacket down the stairs. This is connected by a semi-rigid and vertical rubber rod, itself connected to a short rope-elastic above. The elastic rope is attached to a carriage that follows the user's unrestricted movement down the stairs, rolling on the base of a beam. This light steel or metal truss is located above and perhaps slightly offset from the center to fit any winding staircase. It is itself hung from the top by several anchors that will be fixed on the sides of the ceiling of the staircase on a solid part. If the user falls, he exposes his weight to the rod and the carriage which itself actuates a braking system as illustrated (it could also be a question of braking via a lever-clamping system on the beam). The user has the jacket at the top of the staircase for reuse and down later and so on. DESCRIPTION 1. The present invention relates to an apparatus enabling persons with reduced mobility to remain in their two-storey dwelling by ensuring the continued use of their stairs with their legs without risk of falling and for better cardiovascular health. 2. The stakes of a person with reduced mobility (especially our elders), are known. The dilemma is: should I leave my home on more than one floor because of the risk of falling on my stairs? Systems exist to answer this dilemma but they are expensive. We only have to think of chair lift escalators. These systems 2 are not versatile when it comes time to install them. Moreover, many elderly people are denied their installation because of a staircase too narrow. Even if the installation of these expensive chairlifts is carried out, it remains a non-negligible condition to be considered for the user but also for the Society and the public health: the use of a staircase in a safe and daily way is a undeniable advantage for cardiovascular health. 3. The present invention is a compromise to all these aspects. We take measurements of the stairs and we install a suspension system by a jacket type rescue but stylized (see drawing submitted to this THE SKY HELPER). The user who wants to ride puts the jacket at the bottom of the stairs. It is connected by a semi rigid rubber rod which itself is connected to a short elastic above. The assembly is attached to a carriage that follows the movement without constraint of the user, rolling on the base of a beam. This light steel or metal beam is located above and perhaps slightly offset from the center and fits any winding staircase with customized modules. It is itself hung from above by several anchor rods (could be braided steel cables) that will be attached to the sides of the ceiling of the staircase so on the solid structure of the frame. If the user falls, it offers its weight to the rod and the carriage which itself actuates a braking system as illustrated (it could also be a question of braking via a lever-clamping system on the beam). The user continues his journey and has the jacket at the top of the stairs to reuse it to come down later. NB: An optional remote warning system (Wi-Fi) could alert external personnel when a fall of the user occurs. This under the action of the fall, a contact could be installed under the spring indicated in Figure 3C. 4. With reference to the drawings which illustrate the embodiment of the invention called Sky Helper, FIG. 1A shows an elevation of a typical staircase which shows a user with reduced mobility descending a stairway protected by the present invention. It shows the beam 1 view in section and elevation arranged in the winding staircase and the semi-rigid rubber rod 2 and the jacket 3. This beam 1 made to measure in sections interlocked only by its upper parts is supported all along the stairs by anchors 4 fixed at the corners of the stairwell. FIG. 1B supports more details showing, among other things, the rescue-type jacket 3 which will make it possible to hold the user by a belt on the jacket which will also be provided with collars 5 in order to maintain the rubber rod 2 in a relatively vertical position. Hook with resealable latch or carabiner 6 is attached to the semi-rigid rubber rod 2. This will allow the rod 2 to be moved with the user's movements to drive the trolley-swing set 7 specially designed to roll inside. of the beam 1. An elastic rope-strap 8 of fifty or seventy-five inches long will allow greater flexibility of movements but will also better dampen a possible fall of the user. Figure 2 shows a sectional view of the beam of Figure 1A. Rod anchors or small braided steel cables 4 will support said Sky Helper invention via hooks in prefabricated holes 9 of the beam 1. The steel cables or anchors 4 will be strategically attached to the corners of the stairwell to support the beam 1 all along according to the rules of art and depending on the weight of the user. The specially designed trolley-swing set 7 is shown in part here. A pivot swing system 10 makes it possible to marry the descent or the climb of the sloping staircase, and 4 when the upper or lower step of the staircase is reached by the user, the beam 1 becoming horizontal the pivot 10 of the swing 11 makes flexible the movement of the carriage. FIG. 3A shows a different perspective view of the inside of the beam 1 and a side of the carriage-swing assembly 7 with this time, the detail of the rack 12 (teeth embedded in the beam) and the notch stop 13 which blocks the displacement of the carriage 7 under the weight 14 of the user who falls via the rod 2 attached to the swing 11. FIG. 3B shows more details of the carriage-swing assembly 7 with a view of perspective of its symmetrical half, and its detent 13 on the rack 12 and the pivot 10 of the steel swing that supports the user. It also shows the spring 15 to roll the truck only if no weight caused by a fall of the user is exerted on it. Figure 3C shows a section of Figure 3B in two dimensions. If the swing 11 (not shown here) is subjected to half the weight 14, so to a fall of the user, the spring 15 (one on each side) is crushed and the detent 13 (Figure 3B) s 'pushes on the rack 12 of the beam 1, causing the stop rotation of the trolley-swing system. The elastic rope-strap 8 is stretched and cushioned the fall of the user wearing his jacket 3. The user can not hit the stairs, avoiding the worst. It will be close to the steps but suspended. A contact system (WI-FI) under the spring 15 may be optionally installed to signal to external officials or relatives that the user may have lost consciousness. Figures 4A and 4B, with a front section of the beam 1, in turn show more details on the rolling of the carriage 7. The four wheels 16 (perspective of a single wheel) support the carriage 7. They are equipped with ball bearing. One of the four wheels will be provided with a second serrated wheel 17 with a tab (flap) 18 plastic avoiding the carriage 7 to advance the user during a descent of stairs. The user will hear a rattling caused by the tongue when moving up the stairs. Figure 5 shows a plan view (top) of a typical staircase to demonstrate the adaptability of the beam 1 and its engageable sections that fit the shape of any staircase. The joist sections will be custom made and interlocked with each other by securing them from the top of the joist sections (not the rack and roll rail base) to allow the trolley to roll freely. Each upper and lower step of the staircase will include a cabinet 19 for storing the jacket. 5. Claims The embodiments of the invention, for which an exclusive right of ownership or privilege is claimed, are defined as follows: I.
