in the name of: Louis CLAESEN

B-3740 BILZEN (Belgium) for: "Table for medical and paramedical treatments." 'tr »% - 1 -" Table for medical and paramedical treatments ".

The present invention relates to a table for medical and paramedical treatments comprising a lower frame resting on the ground and an articulated frame which is connected thereto, which carries the table and which can be moved up and down by a motor. roller, the latter being mounted between a part of the lower chassis and a part of the articulated chassis.

Such tables are known.

A certain type includes, for example, a frame which is hingedly mounted on a fixed or lower frame, provided with four pivoting support arms which are each articulated with respect to the fixed frame in order to bring the table, which is connected to this chassis, in its desired position. To this end, the pivoting support arms are connected, two by two, by a bar, on each side of the plane of symmetry of the table. These bars are in turn connected by a small arm. A roller motor is mounted between this small arm and the lower chassis. Moving the roller to the left or right by rotating the helical wheel of the roller motor in one or the other direction brings the table to its highest or lowest position or vice versa.

20 The rupture or wear of any part which relates to the fixing of the roller motor to one of the chassis, or of the parts of the roller motor engaging one another, eg the worm of that -this, may cause the table to fall suddenly. Such incidents have occurred repeatedly over the years.

The object of the invention is to remedy these drawbacks and to prescribe means providing a solution to the problem posed by elements which can be fitted simply from the technical point of view and which are reliable in their action.

In order to make this possible according to the invention, between said lower chassis and the part of the articulated chassis on which said roller motor acts, a damping element is interposed which prevents, the sudden movement downwards of the articulated chassis, during a rupture of a drive member of the roller motor, of a point of attachment thereof relative to one of said chassis 5 or of a point of adhesion relating to the movement of the articulated chassis .

Still according to the invention, said damping element is a shock absorber. In a preferred embodiment, said damping element is a pneumatic damper.

Other details and advantages of the invention will become apparent from the description given below of a table for medical or paramedical treatment, according to the invention. This description is given by way of example only and does not limit the invention.

Figure 1 is a schematic side view with partial section of the table according to the invention in the lowered position. Figure 2 is a similar side view of the table in the higher position.

The table represented by these figures comprises a lower chassis 1 and an articulated chassis 2 which is pivotally connected with respect to this lower chassis 1. The chassis 2 supports the actual table 3.

The articulated frame 2 comprises, in the embodiment according to the figures, four pivoting support arms 4 which each have at 5 a point of articulation relative to one of the side members 6 of the lower frame 1.

Each of the pivoting support arms 4 partially forms a square or at least consists of two parts 4 ′ and 4 "which are mutually square.

On each side of these beams 6, the ends of two pieces 4 "are connected by bars 7 which are articulated at 30 8. Two bars 7 are connected by a small arm 9. The shaft 10 of the roller motor 11 has an application point on this small arm 9. The other application point of the roller motor 11 is located in the articulated connection 12 with a small cross member 13 belonging to the lower chassis 1. The application point of the shaft 10 with respect to the small arm 9 is located in the articulation point 14.

·· »Ύ - 3 -

In order to prevent that during the rupture of one or the other important part for the articulated fixing of the roller motor 11 to the lower chassis 1 or to the small arm 9 or also during the rupture or of the wear the wire of the helical wheel of the motor 5 with a roller 11, a damping element 15 is mounted, according to the invention, between the small arm 9 and a part of the lower chassis 1, in particular the small cross member 13 '.

In the most advantageous embodiment, this shock absorber consists of a pneumatic shock absorber which therefore fulfills the function of shock absorber J and which makes it possible to drop down the table 3 supported by the articulated frame 2 gradually.

Referring to Figure 2, it is noted that the damping element is under pressure. The presence of a weaving element 15 does not form an obstacle to the normal operation of the roller motor 11 when the latter raises or lowers the table 3.

It goes without saying that the invention is not limited to the embodiment described above and numerous modifications could be made without departing from the scope of the patent application.
