Abstract

The invention relates to a sliding board for transferring individuals with reduced mobility, which board is rectangular, has reduced thickness and can be folded. The board is characterised by having rolling elements projecting from the board itself that remain in contact with the user and facilitate the transferral in all directions of said user. The board is formed of two rigid boards, a lower board (4) and an upper board (5), fixed by means of lateral joining elements (3) and having reinforcing ribs (16) and internal rivets (9). Said boards form an internal housing where the spheres (1) forming the rolling elements are embedded, and in which housing said spheres turn. The cavity formed by the cradle (6) of the lower board (4), and the drill holes of the upper board (5) are always smaller than the diameter of the rolling element.

Description

SLIDING IRON FOR TRANSFER OF PERSONS WITH CAPACITY

REDUCED MOBILITY

DESCRIPTION

Field of the Invention

The present invention is about an iron that facilitates the transfer between two points to a person with some type of disability or disability. The iron is a rectangular and flat object. It is used as a bridge between two points such as a wheelchair or a stretcher and any other place such as the bed, the seat of a car, a conventional seat, etc.

Background of the invention

At present, infrastructure for the disabled is improving and so there are bathrooms and toilets adapted to this end that incorporate handles and railings that facilitate the transfer from a wheelchair. On the other hand, there are a large number of utensils that try to make it easier for people who use wheelchairs to move, the continuous transfer that must be made from the said wheelchair to places such as the bed or the seat of a car where, as a rule, there are no handles or railings that facilitate such transfer.

These utensils are of a different nature and in the state of the art there are complex lifting systems or ingenious extensible elements for the chair itself. In this sense, US 6361267 patent describes a mobile seat mounted on the base of a wheelchair. The seat rests on a plurality of spheres that allow the chair base to slide to the side. The side arm is lowered and thanks to some rollers that it includes, it ensures that the base of the chair continues to slide to the selected place: bed, car, etc.

Other types of utensils are less complex and are made up of simple plates that act as a bridge between the points where the disabled person needs to move. The patent EP 2074977 that has been extended to Spain with the number ES 2363184, presents a "Transfer plate" whose main characteristics are the following: It is easily transportable, is lightweight, articulated by a hinge and has a simplified closure . In addition, it has means for reinforcing the joint and at least one mobile element that extends when the plate is deployed. It also has means locking for the element that closes the hinge and, in turn, reinforces the joint.

The utensils known in the state of the art do not adequately solve the transfer, either because of the complexity of the utensil or because in the case of using a simple iron, there is a smooth surface without any complement that helps mobility on it . In order to avoid this lack, the iron is presented, which includes sliding elements on its surface to facilitate the transfer between points of a disabled person.

Description of the invention

It is an object of the invention that the plate has elements that favor sliding arranged on the surface, specifically on the side that is used for the transfer or upper plate, in front of the support surface or lower plate. This is achieved with rolling elements composed of spheres embedded in a cradle shaped like a spherical cap where they rotate freely. The housing formed by the two plates on the plurality of spheres makes said spheres protrude from the surface of the upper plate. In this way, the arrangement of the rolling elements is such that they provide direct contact with the person to be moved.

It is another object of the invention that the plate is light, small and easily manageable to engage between the transfer points. With sufficient strength according to the user's weight. And with the minimum thickness necessary to be able to include the spheres and that they rotate freely. For this, plastic materials, easily moldable, with good strength and cheap are used. In order to favor the coupling of the plate on the different surfaces and under the buttocks of the user, the lateral ends of the plate have several rolling elements that protrude freely through the lower plate and facilitate rolling.

Another object of the invention is that the plate, which is normally manufactured in one piece, can be folded in half for better handling and transport. This is achieved by taking advantage of the two beams (commercial tube 20x1 Omm) that give rigidity to the plate, these beams are made of an aluminum pin bushing which, as a "flush", moves by fixing. The pin is moved by means of a bent rod that is clipped inside the hole formed by the cradles of the lower plate, both in an open and closed position. And it is another object of the invention that the rolling elements be spheres instead of cylindrical or semi-conical rollers. The provision of these rolling elements to the upper plate allows the person to travel not only rectilinearly along the plate, but also describing curved movements that are very useful for certain transfers, such as when Avoid the outstanding wheel of the wheelchair.

One of the main advantages of the plate of the invention is that since it is a complementary element and not permanently adapted to a wheelchair, it is valid for all chair models and is capable of being used in other applications such as transfer people from a stretcher to the bed or vice versa using two or three plates arranged in parallel for that purpose.

Another advantage lies in the low price of the materials used. All are cheaply manufactured plastic materials, which are assembled very easily and are a light and effective object.

Detailed description of the invention

As shown in Figure 1, the plate forms an eminently rectangular floor surface, which is formed by two flat and laminar pieces. These pieces are joined and between them a plurality of solid spheres (1) are placed that rotate on their position with rotational movement but without translational movement. The plate has a greater width in plan in the zone of the lateral ones (2) than in the central zone, since it is this area that will receive in the first instance the person to be transferred and it is convenient that its surface is greater. So that the spheres (1) do not leave the cradles where they are housed, the two plates that make up the final plate must be firmly joined by a sufficient number of joining elements (3). Said joining elements (3) can be removable or fixed. In the present practical embodiment, an alternative formed by clips that are fixed and fixed are shown. The upper plate is jointly joined to the lower plate by a succession of peripheral joining elements (3) and by the action of internal rivets (9). The rivets (9) are applied with buterola and are distributed symmetrically between the rows that form the spheres (1) in the central area. The contact elements between both plates are the spheres (1), the reinforcement ribs (16) and the rivets (9). The reinforcing ribs (16) are internal and can only be seen in the sections.

Figure 2 shows the cross section made to the plate where the main parts are shown: a lower plate (4) that works as a cradle for the spheres (1), and the upper plate (5) which is a flat board with holes with a diameter smaller than the diameter of the sphere (1). The lower plate (4) has a cradle (6) for each sphere (1) and with the union of the upper plate (5) it is avoided that the spheres can leave their cradles (6). In the upper plate (5) there are as many holes as spheres (1) and, once the two plates (4 and 5) are positioned, the holes and the cradles (6) are aligned and form the housings. The cribs (6) have a small hole (7) at their base that makes it easier to keep the housing clean. The sides (2) of both plates are convexly curved and their ends are joined in an overlapping manner (8). The curve formed by these sides (2) favors in every measure the transfer of the person and the placement on any surface. The lower plate (4) has at its longitudinal edges a U-shaped recess (10) where the beam that stiffen the plate (not shown in the figure) is housed. The beam is a 20x1 mm tube that has a bent rod as a pin.

As shown in Figure 3, the hemispherical cradle (6) that forms the lower plate (4) does not in any case have a greater depth than the radius of the spheres (1) that rest inside. What it can have is a minimum depth that guarantees the rolling of the sphere (1) without leaving the cradle (6). For its part, the top plate (5) has a drill that lets emerge slightly less than a third of the sphere (1). These are important characteristics so that the rolling is easily carried out. If the cradle (6) of the lower plate (4) and the hole of the upper plate (5) are too large, an interlocking of the sphere (1) occurs and it would not roll properly. Neither the cradle (6) nor the drill will be in any case equal or larger than the diameter of the sphere (1).

Figure 4 shows how a series of spheres (1) of the same diameter as the spheres used on the rest of the surface of the plate are arranged at the lateral ends (2) of the plate. The number of spheres (1) to be used on the sides (2) is three or four and between them rivets (9) are established that hold both plates together.

As shown in figure 5, in the case of the configuration of the sides (2), the spheres (1) are covered by the upper plate (5) and on top they exit by the lower plate (4). This configuration allows these spheres (1) to turn crazy and facilitate the sliding of the plate on any of the support surfaces where it is to be used. The tips (1 1) of the rivets (9) cross to a plane formed by the line of symmetry (13) established by the spheres (1). To this plane, the external reinforcement ribs (12) existing in the lower plate (4) also extend.

Figure 6 shows a detail of the shape established in the holes in the lower plate (4) and how the ends (14) of said hole are rounded to accommodate inside the sphere (1). On the other hand, the upper plate (5) undulates its surface to constitute a semi-cradle (15) where the sphere (1) can rotate. Between the two plates the corresponding internal reinforcement ribs (16) are established.

Figure 7 shows a detail of the connecting element (3) existing on the sides of the plate. This union is formed by the clipping of the lower plate (4) on the upper plate (5). The end of the lower plate (4) has a narrowing where the bending (17) of the curved end (18) ending in a harpoon tip (19) occurs. The harpoon tip (19) is crimped with the top plate (5) leaving "cloth" with it.

As shown in Figure 8, the support surface of the plate is the cradles between which outer reinforcing ribs (12) are distributed, which increase the flexural stiffness of the assembly and belong to the lower plate (4 ). Said ribs (12) are arranged in the lower plate (4) to avoid aesthetic marks in the upper plate (5), more visible.

Each of the main, lower (4) and upper (5) plates is divided in two by its axis of symmetry so that two subsets are formed. There is a hinge system (20) that allows the plate formed by the two subsets to be in an unfolded or folded position. In turn there is a pin or bolt (not shown in the figure) on each side that ensures the open position, sliding inside the recesses (10) where the reinforcement tubes are located. Said aluminum pins are actuated at the same time by means of a bent steel rod. The bent rod is fixed to the outside of the lower plate (4) in clips (21) integrated in the lower plate (4) both in closed and detached position. The two 20x1 Omm and steel section reinforcement tubes slide inside the U-recesses (10) in the lower plate (4).
