Definitions
- l designates the patients chair which consists of a head part 2, a back rest 3, a seat part 4, a foot part 5, a base 6 supported on the floor, a vertically adjustable base part 7 which is connected to the seat part 4, and a parallelogram arm 8 connecting the two parts 6 and 7 to one another.
- the dotdash line 9 represents the longitudinal axis of the patients chair.
- the dental treatment unit includes an upright and elongate housing 10 which is disposed to one side, i.e., the left-hand side of the patients chair 1 with its longitudinal extent parallel to the longitudinal axis 9 of the patients chair 1.
- a rigid support arm 12 is connected at one end for pivotal arcuate movement in a substantially horizontal plane about a substantially vertical axis 15 near the narrow end 13 adjoining the foot part 5 of the patient's chair 1, through the agency of a support casing 14
- the arm 12 is also connected to the casing 14 for upward and downward pivotal movement about a horizontal axis in the form of a substantially horizontal pin 16.
- FIG. 3 shows the free end of the arm 12 on a larger scale.
- the handle member 25 which is angled and stirrup-shaped is mounted on the arm 12 to be rotatable about a substantially horizontal axis 48.
- the front portion of the handle 25 is disposed between the group of handpieces 19, 20 resting in their housings, on the one hand and the syringe 22 on the other hand.
- the syringe has been pulled out of its housing and only the extensible supply conduit 49 leading to the syringe 22 is illustrated.
- the extensible conduit 49 slides over the handle member 25 and therefore cannot collide with the handpieces situated below.
