    [0003]
    [0004] OBJECT OF THE INVENTION
    [0005]
    [0006] The present invention fits into the technical field of personal means of transport specially adapted for the sick or disabled, more specifically in the case of those powered by motor, and refers in particular to an armchair specially designed to accommodate people with physical disabilities or Reduced mobility in a comfortable way.
    [0007]
    [0008] BACKGROUND OF THE INVENTION
    [0009]
    [0010] The transfer of disabled people, dependent seniors or those with reduced mobility in general is a complicated task to perform even for several people due to the effort involved in moving them, which can cause serious health problems for caregivers, ranging from muscle aches to lumbago or hernias that result in sick leave due to this activity.
    [0011]
    [0012] Currently known in the state of the art transfer cranes that are robust and large and can only be used within the area where the person lives. They also have the disadvantage that they require a lot of space to carry out the transfer, so their use may be restricted to hospitals, residences, etc. Additionally, it should be pointed out that said cranes may cause unpleasant sensations to the user, which may be treated as an object.
    [0013]
    [0014] It is also known that there are additional chairs to wheelchairs that serve to carry out the transfer of the disabled person from the wheelchair to the bed in a manual manner, which have two lifting cylinders to place the person at the desired height, a removable backrest of the structure of the chair, which is removed to make the movement and a sliding seat to place the person as close as possible to the center of the bed.
    [0015] On the other hand, a plurality of lifting wheelchairs are known in the state of the art that allow the user to move from a sitting position to a standing position, as well as a vertical ascent when the user is in the sitting position. or standing. For this purpose, an ascent device is provided with which the lifting frame can be raised in the sitting position as well as in the standing position. The rise or fall of the sitting or standing level substantially increases the freedom of action of the user of the wheelchair and allows the user to reach objects located on high shelves.
    [0016]
    [0017] However, these wheelchairs have several disadvantages. They do not allow to move in the standing position, due to the risk of capsizing. Another additional disadvantage of certain wheelchairs is that during the ascent a backward movement also takes place. This can prevent rollover, but makes it difficult or impossible to access objects from high places. A further disadvantage of wheelchairs of the prior art is their limited ability to move over obstacles or maneuver in a narrow space. Finally, it can be mentioned that in the lifting wheelchairs of the prior art the ascending device requires a lot of space and makes it difficult to access important elements, for example the batteries, of the elevating wheelchair.
    [0018]
    [0019] DESCRIPTION OF THE INVENTION
    [0020]
    [0021] The object of the invention consists of an armchair specially designed to accommodate and transfer people with reduced mobility capacity in optimal comfort conditions, for which incorporates side wheels operable both manually by the user, as pushed by a caregiver or even Automated by the incorporation of a small electric drive motor.
    [0022]
    [0023] The armrests of the chair, which cover the side wheels, are removable, for which they have a lower sector through which they are linked to a supporting lower frame, and an upper sector connectable to the lower sector, on which the user's arms rest. .
    [0024]
    [0025] Thus, the decoupling of the upper section from the lower section of the armrest, it allows partial access to an upper end of the side wheels, so that the user can act on them to move the chair without the need of external help. The decoupling of the lower sector from the frame leaves the side wheels completely uncovered, as well as reducing the overall width of the chair, allowing it to pass through narrow spaces. In the preferred embodiment of the chair, the total extraction of the armrests gives rise to a chair with a total width of 57 centimeters, which allows it to pass through all the door openings, thereby improving the user's autonomy.
    [0026]
    [0027] The incorporation of a plurality of auxiliary elements is also foreseen, such as, for example, an automatic elevation and inclination mechanism for folding the chair to an essentially horizontal position, as well as for raising the seat and the backrest in order to facilitate the lifting of the user .
    [0028]
    [0029] The wheelchair for the disabled of the present invention contributes to solve the current problem, because it offers a new way of transferring people with reduced mobility, achieving improvements against everything known up to now and providing quality of life for both carers and users .
    [0030]

    [0042] PREFERRED EMBODIMENT OF THE INVENTION
    [0043]
    [0044] Next, with the help of the aforementioned figures, a detailed explanation of an example of a preferred embodiment of the object of the present invention is provided.
    [0045]
    [0046] The disabled chair described, shown in Figure 1 in its rest position, is formed by a rolling frame (1) equipped with an elevation and inclination mechanism (2), frame (1) to which is attached superiorly a Armchair module comprising a seat (3), a backrest (4), side armrests (5) and a footrest (6).
    [0047]
    [0048] The frame (1), as can be seen in figures 2 to 4, incorporates side wheels (7) for rolling by rolling as well as auxiliary wheels (8). In this preferred embodiment, the side wheels (7) are of lenticular type, with a diameter of 45 centimeters and manually operable by the user, and the frame (1), of polygonal geometry with 4 sides, has four wheels (8) located in the respective vertices.
    [0049]
    [0050] The armrests (5) which, as seen in the attached figures, cover the side wheels (7), are removable, for which they have a lower sector (9) through which they are linked to the frame (1) and a sector upper (10) linked to the lower sector (9) by coupling corresponding guides not shown in the attached figures.
    [0051]
    [0052] In this way, the decoupling of the upper sector (10) from the lower sector (9) of the armrest (5), upper sector (10) on which a user directly supports his arms, allows partially accessing an upper end of the wheels lateral (7), so that the user can act on them to move the chair without the need for external help. The uncoupling of the lower sector (9) of the armrest (5) with respect to the frame (1) completely exposes the side wheels (7), as well as reduces the overall width of the armchair, allowing it to pass through narrow spaces.
    [0053] In this preferred embodiment, the total extraction of the armrests gives rise to a chair with a total width of 57 centimeters, which allows it to pass through all the door openings, thereby improving the autonomy of the user.
    [0054]
    [0055] In this preferred embodiment, the lower sector (9) is linked to the frame by coupling guides (101) that split vertically from said frame (1), as shown in figures 3 and 4, inside transverse grooves defined in said lower sector (9).
    [0056]
    [0057] The elevation and inclination mechanism (2), driven by an electric motor (11), is coupled to the rolling frame (1). Thus, this lifting and tilting mechanism (2) first allows the folding of the backrest (4) and the footrest (6) to obtain an essentially horizontal user position similar to that illustrated in figures 2 and 3 and, in second place, raise and push the seat (3) forward to facilitate the incorporation of the user, as shown in Figure 4.
    [0058]
    [0059] To that end, said elevation and inclination mechanism (2) has an actuator that firstly drives articulated arms (12) at the front, which can be linked to the footrest (6) for its extension and retraction, and rear oscillating arms (13), linkable to the backrest (4) for its despondency and disengagement. The simultaneous and synchronized action of both arms (12,13) results in the obtaining of an essentially horizontal position of the user.
    [0060]
    [0061] Secondly, with the chair in the rest position of figure 1, the actuator of the elevation and inclination mechanism (2) drives a hydraulic piston (14) connectable to the backrest (4) which, in combination with the oscillating arms ( 13), it pushes upwards to raise the backrest (4) and the seat (3) as illustrated in figure 4, in order to facilitate the incorporation of the user.
    [0062]
    [0063] In the preferred embodiment described here and illustrated in the attached figures, the seat (3) is of conventional type, with a foam and upholstery filling, and can be linked to the frame (1) by corresponding fixing means. In figure 3, there are bars (15) that have a plurality of through holes (16) for coupling said seat (3) through a corresponding plurality of screws Fixing.
    [0064]
    [0065] In an alternative embodiment, not shown in Figures 1-4, the seat (3), also removable from the frame (1), incorporates a through hole to a removable tank designed to temporarily accommodate the user's stools.
    [0066]
    [0067] The incorporation of ear flaps (17) linked laterally to an upper end of the backrest (4) is also contemplated. In the preferred embodiment, the ear flaps (17) displace by folding down with respect to said backrest (4) by ratchet-type hinges. Also, in the alternative embodiment indicated above, the backrest (4) incorporates a hinged lid (18), for access to the removable tank.
    [0068]
    [0069] The actuation of the disabled chair can therefore be carried out by the user himself, who can have access to the side wheels (7) by removing an upper sector (10) from the armrests, or by a third party, who can push said armrests. armchair to be displaced by rolling.
