DESCRIPTION OF THE INVENTION HAVING TITLE: "DEVICE FOR THE TRANSFER OF PERSONS THAT CAN BE INTEGRATED TO A WHEELCHAIR FOR THE DISABLED"

TEXT OF THE DESCRIPTION

People forced to travel in a wheelchair for the disabled, if not equipped with excessive physical strength in the arms or disabled in the upper limbs, inevitably need an assistant for regular transfers from the wheelchair to any other location and vice versa.

At the moment of the transfer they can rely exclusively on the physical strength of the assistant.

The device presented here makes it possible to facilitate the transfer maneuver at any time.

By operating a winch (13), connected by a rope (14) to a harness (23), the seated person is easily raised; rotating the arm (1) translates the person out of the chair.

This device is mainly composed of:

• A telescopic profile made up of pieces (1) and (2)

• One arm free to rotate (1)

• A winch operated by means of a crank (13)

• Two lockable rail feet (11) (21)

The profile (1) is inserted into the profile (2) thus forming a telescopic coupling. The profile (2) is equipped with a hole for inserting a plug with a rectangular base (3); when the device is put into operation, the profile (1) will be placed on it.

A hinge (9) is attached to the base of the profile (2), which connects the profile (4). A plate (10) is attached to the profile (4) with a threaded hole for connecting the foot to the rail (11) by means of the knob (12).

By means of the supports (5, Tab. 4) and (6, Tab. 4) connected to the terminals (7, Tab. 4) and (8, Tab. 4) and connected to the tubulars of the wheelchair, the profile (2) is made integral with the wheelchair itself.

To have a more stable structure in the transfer maneuver of the seated person, a front foot can be inserted (21). This front foot consists of a profile (18) with a possible cap at its end (15), with a plate (19) attached to the base, which serves to connect the rail foot (21) by means of the screwed knob (20) to the plate (19) (Table 4).

The profile (18) can have a rail groove for the sliding of a cut axle (16) on the sides, which will make the foot lockable in the running condition of the wheelchair.

The severed axis (16, Tab. 3 and 4), will make the profile (18) integral with the wheelchair, by means of the connection clamp (17, Tab. 4), connected to a tube that makes up the wheelchair.

The rail feet (21) and (11) can end at the ends with rubber feet (22), which give further stability to the structure.

When the device is closed during the running condition of the wheelchair (Table 2, Fig. 3 and 4), it assumes a configuration that does not hinder the movement of the latter.

At the moment of use, you simply have to open it (Table 1, Fig. 1 and 2) by lifting the arm (1) and locking it at the operating height, letting it rest on the plug (3) with a rectangular base.

Subsequently, it is necessary to open the rear foot (11) by rotating the plate (10) until it comes into contact with the ground; then it will be necessary to rotate the foot (11) and then slide it until it is completely open. After this, it is necessary to open the front foot (21), making it slide and rotate until the severed axis (16, Table 4) will allow sliding in the rail groove of the profile (18); at the end of the stroke, the profile (18) will be able to rotate again until it reaches the operating configuration. In these conditions the device is ready for use (Tab.

1, Fig. 1 and 2).

At this point, it is necessary to connect the rope (14) to the harness (23) that wraps the person sitting in the wheelchair and to operate the winch (13), or other pulling device, to lift it. Once a suitable height has been reached, to further facilitate the maneuver, the armrest of the wheelchair can be raised and, by rotating the arm (1), the seated person can be moved out of the wheelchair (Table 1, Fig. 1 and 2).

By operating the winch (13) again it will be possible to lower the person harnessed to the new seat.

After use, the device can assume a new configuration compatible with the wheelchair's transport configuration (Tables 3, Fig. 5 and 6).

Therefore, it is necessary to close the profile (1) by placing the arm in a parallel position with the armrests of the wheelchair; then it is necessary to close the rear foot (11) by rotating it in the opposite direction to that of opening, until it becomes parallel with the plate (10); at this point, the foot (11) and the plate (10) can be rotated until they touch the profile (2) with the toe of the foot (11) (Table 3, Fig. 6).

Subsequently, the front foot (21) must be closed by simply rotating it in the direction of the rear wheels, until it touches the rear wheel corresponding to the connection side (Tab. 3, Fig. 5 and 6). Finally, the wheelchair can close normally, without being hindered by the lifting device; therefore, in this configuration, the device is made transportable with the wheelchair (Table 3, Fig. 5 and 6).
