Memory and programming device for one fully programmed dental treatment chair

The invention relates to a dental Treatment chair ", the seat and back of which are άμ ^ ΐι hydraulic, pneumatic or electric The drive can be swiveled or adjusted in height.

The purpose of the invention is an adjusted chair position after a dental treatment on a punch card or other storage medium, which is removed from the chair to keep it in a remote location, e.g. in a medical file. He comes Patient.for a second or further treatment, the chair can be removed by removing the punch card or the storage medium from the card index and inserting it into the reading device of the chair in the same position that led to the recording on the storage medium.

Chairs of the type mentioned are known which are programmed for one or more specific positions. The positions are usually assigned to specific types of treatment and are always the same for these. They don't care about that. physical dimensions of the patient and if a correction is made, this position cannot be saved «,

The present invention is intended to eliminate the aforementioned disadvantages.

The object is achieved according to the invention in that in a treatment chair with conventional setting of the individual chair functions a device for creating a storage medium, such as 3. a punch card, a punch card punch in addition to actual value potentiometers with Throw actuators and a reading device installed.

The achieved advantages of the invention are that all manually adjustable chair positions by a storage medium E.g. the punch card can be recorded and copied again at any time, which is the working time of the Doctor's shortened and also gives the doctor a reference to the previous work ', there is usually one a specific chair position is assigned to a specific treatment.

An exemplary embodiment is shown in a schematic drawing and is described in more detail below:

Fig. 1 shows an actual value transmitter with actuators, punch card and stan device,

Fig. 2 shows a schematic representation of the punching and reading device.

To create a punch card, a non-punched card (4) is inserted into the part of the card trolley (31), which is assigned to the punching device.

By operating the conventional controls, it moves 'The chair in the desired working position, being there The various actual value transmitter potentiometers (11, 12, 13) are set via links. By pressing one additional control button, a circuit is closed via a switch (29), i.e. a motor (1) is turned on Switching amplifier (8) switched on until the resistor bridge consisting of the actual value transmitter potentiometer (ii) and the adjuster (9) is calibrated »

Actuating the motor (1) causes the punched card to be shifted in the vertical direction. After balancing of the bridge from the actual value potentiometer (11) and the adjustment control (9) of the switching amplifier (8) is actuated via the relay (32) short of the electromagnet (6) by the Absehaltimpuls, AEV a punch (g) a perforation of Card (4) causes. A delay relay (32 ') actuates a step switch mechanism (34) via an electromagnet (33), which moves the punch card (4) sideways.

At the same time as the stepping mechanism, the switch (io) is also turned by one step and thus one new second resistor bridge is formed, which consists of the actual value potentiometer (12) and the setting controller (9). The switching amplifier (8) now ensures a vertical one again Shifting of the punch card (4) into which now by the switch-off pulse of the switching amplifier (8) via the relay (32), the electromagnet (6). and the punch (5) a hole is made.

A delay relay (32 *) again provides a "E" magnet (6) for the operation of a step-by- step mechanism (34) u ^ß d switches (1ο). In addition to a lateral displacement of the punch card, a third resistor bridge is formed from the actual value potentiometer (13) and the setting controller (9). Again, the adjustment of the bridge results in a vertical displacement of the punch card (4) and the switch-off pulse of the switching amplifier (8) results in ^{a perforation via the relay (32), the 11} E "magnet (6) and the stamp (5) A delay relay (32. ') again ensures, via an ¹¹ E "magnet (33), that a stepping mechanism (34) is actuated and the switch (io) is moved. Since one of the chair positions is retained in this way, the switch (29) is subsequently released via a cam or pin. A second chair position can now be punched into the card or the card (4) can be removed. If a second position is to be punched, the position is moved by hand and punched by closing the switch (29) by pressing a button, as previously described. If the card (4) is removed from the chair, the card trolley (31) is brought into its rightmost position via a return mechanism.

Should now be a chair position due to a perforated card (4) are set, the card (4) is introduced into the part of the card trolley (31) which is the reading device assigned.

By inserting the punch card, a switch (35) is actuated and thus the contacts from 13 or 18 ¹ to 25 or 25 '. After pressing the switch (29) a bridge is now formed from the carbon resistor (14) via the tap (15) and the potentiometer (11), which opens the "E" valve (26) for the associated chair adjustment until it is adjusted until the ■ switch-off pulse causes the punch card (4) to move sideways using the relay (32), magnet (33) and step-by-step switch (34) and also switches the switch (1g) on. By adjusting a new bridge, which is formed by the carbon resistor (14) via the tap (15) and the potentiometer (12), the "E ¹¹ valve (27) for the associated chair adjustment opens until the switch-off pulse of the switching amplifier (8) Lateral displacement of the punched card (4) is effected by relay (32), magnet (33) and step-by-step switch (34) and also switches the switch (io). Now the third bridge is calibrated, which is made by the carbon resistor (14) via the tap ( 15) and the potentiometer (13).

Until the adjustment, the "E" valve (28) is opened, which effects the assigned chair adjustment until the switch amplifier (8) switches off the punched card (4) by means of Kelais (32), magnet (33) and stepping mechanism (34) ) takes place and the switch (io) is switched on. With this third switching pulse, the switch (29) is again activated by a cam or. The pin of the step-by-step switch (34) is open. If a second chair position is punched on the card (4), you can do this by closing the switch (29). When the card (4) is removed from the chair brings a return mechanism the card n (31) back ία the rightmost position.
