DESCRIPTION:
BRIEF SUMMARY
FIELD OF THE INVENTION
The present invention concerns a table with mobile elements having ergonomic adjustment possibilities and able to be used for handicapped persons.
BACKGROUND OF THE INVENTION
In the sphere of school education and more specifically in teaching establishments for handicapped persons, it is essential to provide these persons with ergonomy so as to obtain satisfactory results.
In fact, the teaching of data processing or certain manual subjects is carried out with known types of equipment which are inadequate, either because they cannot be adjusted in certain directions, or because their dispositions are specific and intangible, for example the controls of movements of certain portions of the table which are not accessible to handicapped persons.
In addition, when these handicapped persons use wheelchairs, the equipment must allow the seat to be placed and be equipped with means for protection against impacts generated by the movements of these wheelchairs.
Furthermore, it is essential that these items of equipment are extremely stable as they are generally relatively close to one another, which increases the risks of turning over.
The main criterion here is to provide a multipurpose capacity.
In fact, the purchase price of these items of equipment is of necessity relatively high considering the degree of sophistication with the result that the percentage of use needs to be sufficient so as to justify its purchase.
The increase of the percentage is quite natural when a given table can be used for various applications.
SUMMARY OF THE INVENTION
The invention also concerns a multi-purpose table including a large number of adjustments ensuring a specific ergonomic adaptation for a handicapped person, is compact, can have its mobile elements controlled when moving and which is extremely safe as regards its operation.
To this effect, the ergonomically adjustable mobile element table of the invention, able to be used by a handicapped person and including a frame with a base and at least two stanchions integral with said base and a fixed plate integral with said stanchions, is characterized in that it includes at the rear one first mobile plate able to move vertically between a bottom retracted position and an upper working position in front of the fixed plate and a second plate able to move horizontally and disposed immediately above and parallel to the fixed plate.
More specifically, the first plate able to move vertically includes an auxiliary plate able to move horizontally with respect to this first plate offset towards the front so as to be superimposed with the fixed plate.
As for the fixed plate, this includes an auxiliary plate able to move horizontally with respect to this fixed plate and is offset towards the front and is of the computer keyboard support type.
According to the preferred embodiment of the invention, the stanchions of the fixed plate include height adjustment means with respect to the frame, said height adjustment means including a first and second jack associated with each stanchion, each stanchion including two telescopic portions between which the corresponding jack is inserted, the first portion being integral with the base of the frame and the second portion supporting the fixed, mobile and auxiliary plates.
According to one variant of the table of the invention, the height adjustment means include a telescopic jack which is single for at least two elements, the lower element being integral with the base of the frame and the upper element supporting the fixed and motile plates.
According to one improvement of the table, the frontal edge of the fixed plate includes a control box able to move laterally.
In the case of the table of the present invention, electric motors are provided to move the mobile plates, as well as end of travel sensors and force sensors so as to avoid jamming and mechanical pressure effects.
The frame also includes a clearance on the front face so as to give access of handicapped persons to wheelchairs.
Similarly, the frame includes a rear
