DESCRIPTION:
BRIEF SUMMARY
The present invention relates to a mobile and pivoting circular platform for transferring a motor-handicapped individual, for example from his chair to a toilet seat or to his bed and vice versa.
It is well known that the operation of transferring an invalid from a chair to a toilet seat or to a bed or vice versa, is performed with the help of one or more people, accompanied by the difficulties inherent to the weight of the invalid and the lack of mobility in his lower limbs. The task of turning the invalid round and getting him out of his chair is all the trickier because rest rooms are always tight on space.
The state of the art, and in particular U.S. Pat. No. 2,963,713, DE-A-2 749 146, U.S. Pat. No. 5,507,044 and FR-A-2 526 312, describe devices which employ a baseplate on which there is mounted so that it can pivot, a plate bearing a support with a handrail, and which therefore allow the invalid to be pivoted through 180.degree. once this invalid has been installed, standing up, on the plate. Furthermore, in the first two documents, the device has integral wheels which allow the device to be shifted when unladen, for example, to bring it up close to a toilet pan or to take it away for storage.
None of these devices satisfies the constraints imposed by the non-functionality of the lower limbs, namely: for an invalid who moves along dragging his feet to gain access to it, handicapped individual or the helper might become caught, order to prevent any catching when the invalid is taking his place thereon, during turning,
The object of the present invention is to provide a simple piece of apparatus in the form of an extremely low platform which, allowing the invalid to be stood up more easily, is equipped with a very robust handrail which allows this handicapped individual to hold himself upright for the very short moment during which he is pivoted to bring his posterior to face a toilet seat or a bed, before he can sit down without any twisting or effort from his lower limbs.
The invention therefore relates to a platform made up of a baseplate, a circular plate mounted so that it can pivot on the baseplate with the interposition of means for centering it, guiding its rotation, and supporting it, a handrail in the shape of an arc of a circle connected to the plate by two telescopic uprights and two wheels mounted so that they are free to rotate at the ends of an axle parallel to a diameter of the plate, outside the latter and arranged on the opposite side to the region via which this plate is accessed, the wheels being arranged in such a way that they come into contact with the ground only when the platform is tipped toward them.
According to the invention the baseplate consists of a circular metallic disk of approximately the same diameter as the plate while, on the one hand, the plate, which also consists of a metal sheet, is secured to a protective circular edging extending right down to the baseplate and, on the other hand, the members of the two uprights are connected by a horizontal crossmember which, placed at adult knee height, is itself reinforced by an inclined tube extending between this crossmember and the front part of the plate.
By virtue of this arrangement, access to the platform is easier and, if need be, by resting his shins or knees against the horizontal crossmember, the invalid can stand himself up by pulling with his arms, gripping the handrail, without this generating a tipping moment that would disturb his stability.
Advantageously, each of the ends of the arc-shaped handrail is extended, beyond where it is attached to the upright, by a return bent into a semicircle and downward.
Each bent return thus forms a handgrip which, being easier for the invalid to grasp in the phase in which he is standing himself up, has the advantage of having no edges which may catch on his clothing or that of the helpers.
Other features and advantages will emerge from the description which follows with reference to the appended diagrammatic drawing which depicts, by way of example, one embodiment of the
