Description

Title

Mechanical mobile ramp for use by people with or without a wheelchair.

Object of the invention

The present invention is directed to people with physical disability of the lower motor apparatus, the objective being to improve the quality of life of those people who are not capable by themselves of overcoming architectural barriers such as stairs. The invention is especially useful for buildings that do not physically have space to place a fixed ramp or even could not place an elevator. The absence of works for its installation makes it very appropriate for protected buildings or of artistic-cultural historical interest. The system is also valid for use abroad and can be carried from one place to another for temporary use. It can also be applied to facilitate the use of loading and unloading equipment.

Sector of the Technique

The invention falls within the field of equipment technique for the elimination of architectural barriers for people and more specifically in relation to equipment to save stairs

State of the Art

In Spain, 6% of the population has disabilities related to reduced mobility. Of this group of people, approximately 65% have problems to leave the house independently. The usual solution to solve this problem is to combine a conventional staircase with a fixed ramp of regulatory slope in the area of passage. But in many occasions the available space does not allow this combination and the slope of the ramp is excessive. The solution provided by the chair lifts does not solve the problem of people who use the wheelchair and the lifts need a floor space that is not always available. In addition, these last two solutions are usually not accessible to people who do not usually use the building. Finally, unlike other models of mechanical ramps on the market that can only save one or two steps, the proposed system saves complete sections of stairs, and is susceptible to installation outdoors, on the outside of buildings.

Description of the invention

The ramp that the invention proposes completely solves the different cases that may arise. It is fully automatic, so that at any time and acting on a button can cover the entire flight of stairs facilitating access to anyone. Because it is hydraulically operated, its use is safe both inside and outside buildings.

It consists of two transversal metal plates fixed to the ground. One upper for the rotation supports and the other lower one to hold the hydraulic cylinder (s).

On this structure is located the mobile part that constitutes the actual ramp, with its lateral rails and skirting boards. The ramp is formed by a tubular metal structure conveniently reinforced to support the weight of a person in a wheelchair and his companion. The upper part of the structure and the ramp are joined with the supports by a horizontal axis, allowing the ramp to be tilted, while the lower part of the ramp is free. This mobile part has a straight section resting on the ground and two supporting posts. One of these posts has the control elements, the other holds a safety door that prevents leaving the ramp when it is elevated or moving. The system has an emergency system for cases of lack of energy.

Hidden between the structure and the ramp are one or two hydraulic cylinders, (depending on the type of application), which are responsible for lifting the ramp so that it passes from its resting position (inclined) to the working position (horizontal flush with the floor of the top of the stairs). The cylinder rods are joined to the movable part or ramp with bolts forming a deformable triangle whose vertex is the axis of rotation common between the ramp and the structure. The F.OEPM05 / 06 / 2015F.EfectivaP201400856Nº application12 / 06 / 2015carrera and the situation of the cylinders are calculated in each case according to the height to be saved and the slope of the staircase. This also ensures that the ramp will remain horizontal with the cylinder rod fully extended. The hydraulic cylinders are driven by a conventional electrohydraulic power plant comprising; a hydraulic pump mechanically coupled to an electric motor, a hydraulic oil tank with level, thermometer and plugs, a return filter and a control distributor. The pressure outputs of the plant are connected to the hydraulic cylinders with fixed steel pipe and flexible hoses. Therefore, this electro-hydraulic power plant can be placed anywhere on the stairs, close to the ramp, where, in compliance with current legislation, the necessary space is available and there is, or may be, a point of supply of electric current.

To prevent entrapment during the movement of the ramp, lateral and frontal protections are provided that prevent access to the lower part of the ramp.

When for reasons of space the ramp occupies the entire width of the ladder, its tilting is produced by two or more hydraulic cylinders, and the floor is raised on one of its sides leaving free the rungs of the central part of the ladder for use normal. For this, one of the rails of the structure of the ramp has several hinges on which the floor is fixed. The system of raising and lowering the ground, as well as keeping it fixed is fully automatic. Transverse reinforcements are placed half-hidden on the steps of the stairs.

Finally to facilitate the assembly in temporary uses, a lower support structure is added, as well as two wheels that facilitate its displacement to the final place where it will proceed to anchoring

Description of the drawings

To complement the description that is being made and in order to help a better understanding of the characteristics of the invention, a set of drawings is included as an integral part of this description. These drawings are exclusively illustrative, not conditioning the design or the impossibility of adhesion and combination with other techniques.

Figure 1.- Shows a side view of the ramp in its low position F.OEPM05 / 06 / 2015F.EfectivaP201400856Nº application12 / 06/2015

Figure 2.- Shows a side view of the ramp in its high position

Figure 3.- Shows the front view of the ramp in its low position

Figure 4.- Shows the front view of the ramp in its high position

Figure 5.- Shows the side view of the ramp with the raised ground Figure 6.- Shows the front view of the ramp with the raised ground

When the ramp is low (figures 1 and 3) the short section is parallel and flush with the ground, facilitating its access On the contrary when the ramp is high (figures 2 and 4), the long section is parallel and flush with the part high of the ladder so it is very easy to access it from the top of the ladder.

To go up, the user presses the travel button and the door (5) opens automatically. When the person or persons are inside the ramp, the door closes and the hydraulic system activates the cylinder (4) causing the ramp to tilt on its axis of rotation. A detector controls its inclination so that when the initially inclined part moves to the horizontal position it stops moving. A set of safety valves blocks the cylinders preventing movement of the ramp. In this position it is very easy to travel on the ramp and disembark at the top of the stairs.

On the contrary when the user wants to go down, if the ramp is in its low position press the drive mechanism and wait until the ramp stops being horizontal the longest stretch of the ramp. From this moment, the person or persons can enter the ramp and circulate through it until the part immediately before the inclined area. (If the ramp was in the high position, by finishing it using another person, you could enter the ramp directly). When you reach this point press the down button and the ramp will begin to swing down gently. When the front part rests on the floor the door automatically opens allowing the user to leave.

When for reasons of space the ramp covers the entire width of the staircase (figures 5 and 6), the floor has side hinges. When the ramp reaches the resting state in the low position, automatically, an electric moto-reducer motor (8) rotates a threaded spindle (9) which causes the displacement of its nut and the connecting rod (10) , fixed to it, go from being in a position inclined to almost vertical making the floor turn on the lateral hinges and thus

Abata on the vertical plane. In this way the central part of the rungs of the F.OEPM05 / 06 / 2015F.EfectivaP201400856Nº application12 / 06 / 2015escalera is accessible for use in the usual way.
