    5 OBJECT OF THE INVENTION
    The present invention relates to an electric wheelchair that incorporates a crane mechanism, which allows the transfer of the disabled or dependent person from the wheelchair itself to any desired surface, such as a
    10 bed, a toilet, a stretcher, etc. and vice versa, from said surface to the wheelchair.
    The object of the present invention is an electric wheelchair that allows the transfer of the disabled person to be carried out without using the classic cranes, and in turn allows the caregiver to perform the movement without making any type of
    15 effort, facilitating the personal hygiene work of the dependent person and providing greater security at the time of the transfer, which translates into an improvement in the quality of life of the caregivers and the dependent person.
    BACKGROUND OF THE INVENTION
    20 The transfer of disabled people or elderly dependents is a complicated task to perform even for several people due to the effort involved in moving them, which can lead to serious health problems for caregivers, ranging from muscle aches to low back pain or hernias. translate into work leave
    25 due to this activity.
    Currently there are transfer cranes that are robust and can only be used within the enclosure where the person lives. They also have the disadvantage that they require a lot of space to carry out the transfer, so their use can
    30 be restricted to hospitals, residences, etc.
    It is known the existence of an additional chair to the wheelchair that serves to transfer the disabled person from the wheelchair to the bed in a manual way, which has two lifting cylinders to place the person at height
    35 desired, a removable backrest of the chair structure, which is removed to be able to


    perform the movement and a sliding seat to place the person as close as possible to the center of the bed.
    Moreover, the invention patent ES2369454B1 refers to a lifting chair for
    5 manipulation of disabled people, which consists of a chair structure with aseat provided with an opening closed by a practicable cover to allow thedisabled or chair user can perform their physiological needs sitting,where the seat and the backrest are removable with respect to the structure of the chair forallow to place the disabled person, and where the chair comprises a hydraulic cylinder
    10 to carry out the lifting of the structure of the chair and therefore the disabled in that chair, for later transfer.
    The two chairs mentioned above, although they fulfill their function have a series of limitations, among which are that the caregiver has to perform a
    15 movement of rotation and thrust of the dependent person that can affect their health, and the use is limited to indoor since they do not have a structure optimized for use outdoors or on uneven terrain.
    Therefore the known solutions of prior techniques do not offer answers fully
    20 satisfactory to the current problem. The electric wheelchair of the present invention helps to solve and solve the current problem, as it offers a new way to carry out transfers of disabled people, thus achieving improvements compared to everything known so far, and providing quality of life to caregivers Already users
    25 DESCRIPTION OF THE INVENTION
    The present invention relates to an electric wheelchair comprising a rigid chassis, a set of wheels formed by the front wheels and the rear wheels, a seat, armrests and a backrest, where the rigid chassis in turn comprises a
    30 seat lifting mechanism and a crane mechanism.
    The seat lifting mechanism allows the person to be placed at the desired height, that is to say at the same height as the surface where it is desired to position it, where the seat lifting mechanism comprises a lower plate attached to the chassis, an upper plate
    35 attached to the seat and a scissor mechanism actuated by an electric actuator.


    The armrests are foldable around a transverse axis, so that a free end thereof rises from its resting position or horizontal position, to an elevated position, and comprises an anchoring device disposed at said free end of both armrests that allows to attach a patient restraint harness once
    5 said harness has been arranged below the user's legs and optionally on the back and back of the head, for the subsequent lifting and transfer of the person with respect to the wheelchair chassis.
    The crane mechanism comprises an actuator connected by one end to the backrest and by
    10 another end to the armrests that allows the person to be lifted once he is held by the harness attached to the anchoring device arranged in the armrests.
    The armrests and the backrest are rotatable at least 90º around a vertical axis
    15 with respect to the rigid chassis, being preferably because the chair comprises a rotation mechanism, which allows the person who is held by the harness to be placed on the surface on which it is desired to position it. For this, the chair is placed with its back facing the surface where the patient will be positioned.
    Optionally, at least one of the armrests is foldable around the transverse axis from the raised position to an essentially vertical position, to remove the chair by a linear displacement once the harness has been disengaged from the anchoring device, without interfering with the person.
    25 The chair also includes a control that allows to control the movement of all the actuators and wheels of the chair.
    The electric wheelchair of the present invention simultaneously offers the
    30 features of an electric wheelchair and a transfer crane, with an optimum level of performance in both aspects. By incorporating the electric wheelchair a crane mechanism, it allows the transfer of the disabled or dependent person from the wheelchair itself to any desired surface such as a bed, a toilet or a stretcher and vice versa.


    In this way it is possible that the transfer of the disabled person is carried out without the need to use the classic cranes, and in turn allows the caregiver to perform the movement without making any effort, facilitating the personal hygiene tasks of the dependent and providing a greater security when performing the
    5 transfer, which translates into an improvement in the quality of life of caregivers andthe disabled person
    The main advantage offered by the electric wheelchair of the present invention is that it allows the caregiver to transfer the user without taking the risk to which
    10 are commonly subjected, such as back injuries or hernias that appear after a certain time.
    In addition, it provides advantages over transfer cranes since by understanding a crane mechanism incorporated in the chair, it can be used anywhere,
    15 both outdoors and indoors, and provides good maneuverability in confined spaces, or at any time that is required. Finally, being a wheelchair that groups the advantages of electric chairs and cranes, improves the existing and achieves a reduction in the price.
