Abstract

The foldaway armrest and support handle is fitted at the side of the toilet for use by the infirm. It has a common motorised slow drive associated with both the arm rest (10) and support handle (16) so that it does not swivel up or down too quickly which could injure a slow moving person. A gear wheel is pref. provided at the end of the armrest (10) nearest the wall where it can be set in motion by the worm mounted on two sides. The foldaway movement of the movable armrest can be triggered by the release button (30).

Backrest: "Folding handle ..." 08/25/80

The invention relates to a folding handle for the physically handicapped, with an armrest and support handle.

Such a folding handle for the physically handicapped usually consists of the actual armrest, which is horizontal when in use the wall protrudes and with a so-called support handle on the the same wall. Both handle parts can be moved in a pivot point stored on the wall.

Such a rotatably mounted folding handle forms together with a fixed handle, with a handle arranged on the side of a toilet is, a folding handle set. The functional unit toilet, more fixed Folding handle, rotatable folding handle, is handled in such a way that the toilet is initially sideways from the wheelchair user when the handle is folded up is approached. The wheelchair user then swings onto the toilet, leaning on the fixed handle, and then to the

rotatable handle from the vertical wall position to the horizontal To move the position of use. The physical evacuation process in the physically handicapped, especially in the paraplegic, is with considerable effort and takes up to 45 minutes, so that the support aid of the second handle is required.

Now is the lowering of the rotating handle for a disabled person involves considerable effort, sometimes impossible depending on the degree of the handicap, so that the help of a second person is required will. This help in the intimate area of the toilet room is a psychological burden.

The invention has the task of operating a rotatable The folding handle is also possible for the severely disabled and also the use of a second person in the intimate area of the toilet room to make dispensable. It should be noted that, because of the slow sequence of movements of a disabled person, the loosening of the handle from the wall position and the transition to the horizontal position of use, not quickly, i.e. under the effect the force of gravity, rather it must be controlled slowly with a delay in order to avoid injuries.

The invention solves this problem in that it is based on a folding handle with armrest and auxiliary support handle, and it is characterized

This essentially consists of the actual Armrest 10, the auxiliary support handle 16, the gear wheel 11, the worm 12 mounted on two sides. These moving parts are motorized Drive preferably assigned to a DC motor. It is within the scope of the invention to use a different motor drive, for example use a compressed air or hydraulic drive.

At the end of the armrest 10 near the wall, the gear 11 is arranged,

this in turn by the screw 12 mounted on both sides in motion can be set. The high gear ratio made possible in this way accommodates the low-speed drive.

The gear 11 is according to a special feature of the invention with the contact-making switching pin 13, which works as a pole changeover switch, equipped. The switching pin 13 corresponds to the touch contacts 21, 22, which serve as limit switches for the respective positions.

The required slow movements of the armrests 10 are driven via an angle 15 whose shaft is coupled to the motor shaft is effected by the DC motor 20. Gear 11, worm 12 and switching pin 13 are surrounded by a protective housing 14 to move the Protect parts from manual access. This is particularly important when physical and mental disabilities work together.

A fixed handle and the rotatable handle 10 form the Handle set. The fixed handle has the trigger contact 30. Depending on the type of disability, this can also be rotatable Be attached to the handle. In this case, too, the contact switching capacities must be routed through the hollow tube of the handle.
