Support device for operating tables or chairs

The invention relates to a support device for operating tables or chairs.

Known operating tables generally have a platform or an upper table for receiving the patient, this upper part on a movable or fixed base part is arranged so that the height of the upper table with respect to the base part can be adjusted as desired. The arrangement of the horse and the mechanism required for height adjustment is usually relatively complex and expensive. ■

The object of the invention is to create a support device for operating tables or chairs that are under avoidance the disadvantages of known arrangements in a very simple way

allows an adjustable support of the upper table.

The problem is solved with a support device achieved for operating tables or chairs that are featured is by a foot part, a connected to the foot part and inclined with respect to the vertical support column, one in relation on the inclined support column displaceable support which can be moved up and down with respect to the foot part, one of the displaceable Support carried member for receiving the patient and members for raising and lowering the sliding support.

The invention is shown in the drawing below Äus Ausführungsbeispielen explained in more detail. Show it:

Figure 1 - an operating table in side view and Figures 2 and 3 - partial views of the support members of the operating table from Figure 1.

In the illustrated embodiment of the invention, an operating table has a displaceable base part 1, this can of course also be permanently arranged. A support column 2 with a rectangular cross-section is attached to the base part 1 and inclined with respect to the vertical. So lie two opposing surfaces in vertical planes while two other opposing surfaces lie in inclined planes.

Inside the inclined support column 2 there is a support in the form of a platform or an upper table 4 for receiving of the patient. When a pedal 11 is operated, the piston or ram 3 is actuated by hydraulic means (not shown) raised or lowered. Neither the hydraulic means nor the structure of the Obertlsch form the core of the present invention.

The top of the stamp 3 carries a bracket 5, which in turn carries the upper table 4 for receiving the patient. The support column2 is on the ■ vertical planes with a set of 4 bearing cushions each

(Bearing pads) 6 provided with low friction, which protrude into the interior of the column and rest on the punch 3. On each of the other two walls is a pair of pressure _{pads (pre s} sure pads) 7 and a pair of Drucklagerrolleri (pressure bearing rollers) 8. The rollers 8 on the front or lower wall 9 are arranged over the pressure pad 7, while the Rollers on the rear or top wall Io according to Figures .1 and 2 are arranged on the floor. The bearing cushions and RoI-. len are adjustable so that the pressure they exert on the stamp can be varied. This setting also enables wear compensation.

When the ram is raised and lowered, it runs onto the Pressure pads and rolls.

According to the invention, the inclined support column generated loads exploited to keep the slidable member in any desired position with respect to the fixed inclined support column to keep. As a result of the inclination, the displaceable member is always loaded in one direction. In operation, the roles and / or bearing cushions are guided against the displaceable member, to compensate for signs of wear and tear.

It is also possible that the sliding member instead of one Upper table accommodates a seat of an operating chair.
