or. to enable the patient's knee joint situation, on the other hand, it also enables the patient to sit down on the toilet seat and without great exertion also to rise from this again.

This object is achieved in that the support of the support device is arranged on (at least) one column, which is designed in a teiesköpäiftiig and equipped with a .dämpf th Feaiijt device such as an air spring with a certain counterpressure and a stop device that moves downward against the pressure the spring device is limited to an adjustable height.

By this Malinahmen it is achieved that not only the seat is infinitely precisely adjustable in its height of use, but also that sitting down as a consequence of the counter pressure the gas spring takes place without great effort and due to the supporting pressure effect of the gas spring. when you get up, you also get up from the seat. is made easier.

In order to be able to put the support device out of operation when the toilet is used by non-disabled people, let yourself be According to a further development of the invention, the toilet seat on the carrier .klappbar .befestigen.

In addition, the wearer of the support device can also be provided with a hand rest to give the patient an additional one To give help. In particular, the change of seat from the wheelchair to the toilet is made possible by this additional handrest relieved. In the r.ahmsn-like handle you can also accommodate clamping inserts, on which, for example, paper rolls can be hung, or age- * native soap dish inserts, ashtrays, towel holders, also support devices, and the like.

If the support device consists of several columns, the gas pressure spring could be accommodated in one column while a second column can be designed as a stop device or accommodate a stop device in itself could. Other pillars could serve as guiding devices.

However, an arrangement in which there is only one column, in dijr both air spring and air spring, is particularly compact Anchor device is housed. It is advantageous if the stop device according to yet another Further development of the invention consists of a vertically adjustable and fixable mounted rod in the carrier lower end strikes against the bottom plate of the column to limit the movement of the carrier downwards.

The support device could also be designed so that the foldable toilet seat is designed to be movable on two sides is.

A construction has proven to be particularly favorable in which the carrier is a standing column fastened to the floor comprises a rectangular profile that acts as a guide for another displaceably arranged with respect to the upright column Rectangular profile tube is used, at the upper end of which is the support for the toilet seat and a compression spring with a damping device are arranged in such a way that when a toilet user sits up under his weight, the toilet seat moves against the spring force and the damper effect down to the position of use.

The compression spring with damping device can be a mechanical one Spiral spring .be with oil damping device, especially However, a gas spring is lightweight and inexpensive.

within the .Teleskoprohre has the advantage that the Overall arrangement from the outside very compact and easy to cleaning, there is also the mechanical advantage that tilting forces, caused by the influence of the gas pressure spring, be avoided, which could occur more easily when mounted outside the telescope.

The upward movement of the upper telescopic tube 42 can be limited by adjustable stop devices attached to the lower end of the upper tube 42, which abut against a corresponding stop extending from the lower tube 44, for example against one of the wheels 76 or 80. Another possibility would be to use the gas pressure spring 62 as a stop means, since this has a maximum extension length. The adjustability could be achieved by attaching a similar second block next to the block 68, through which the piston rod 100, similar to the rod 58, is slid out upwards and ends there again, for example, with a ball, the block (reference number 3-: 102 then in turn could have a locking screw - similar to the device 70, 72 in order to be able to achieve a certain maximum extension length by jamming the rod 100 in the block ¹ 102 and thus the desired maximum height adjustment.
