Definitions

  • a dental treatment assembly comprises a p chair and a dental treatment unit supported by the chair which is mounted [52] 0.5. CI among a base for adjustment in a generally vefliwl direction rela- 5 1 m "HA6" 9 02 tively to the base.
  • the dental treatment unit includes a hous- [58] Field at Search ..32 22; 4/263 g. a dental hand appliance Support arm Pivotally connected to the upper surface of the housing and a dental spittoon unit mounted on the upper surface of the housing.
  • This invention relates to a dental treatment assembly comprising a patients chair and a dental treatment unit supported by the chair which is mounted on a base for adjustment in a generally vertical direction relatively to the base.
  • the head of the dental unit is adapted to be inclined about a horizontal axis, and from one side surface of the inclinable head there can be pulled out a jib-like telescopic arm of relatively small cross-section which at its free end carries a housing unit for dental hand appliances, for syringing and drilling.
  • the extendible conduits to the hand appliances and the like are disposed between the dental unit head and the head appliance housing in the open and, as long as the hand appliances are in their housings, are slightly tensioned by a winding device for the flexible conduits which is arranged in the dental unit.
  • the dental unit with the telescopic arm can be pivoted about the tubular upright, the housing unit for the hand applicances describing, in a plane situated above the patient, an arc the radius of which is adapted to be varied by the variously selectable lengths to which the telescopic arm can be pulled out. Also, the height of the pivoting plane above the patient can be varied by different inclinations of the dental unit head.
  • the invention proceeds from the realization that the dental apparatus of the type described hereinbefore is disadvantageous since when the hand appliance housing unit is pivoted on an are situated in a horizontal plane above the patient, the heavy dental unit must also be pivoted as well. Easy adjustment of the hand appliances is prejudiced as a result. Furthermore the dental unit cannot be used for fitting a dental spittoon unit, since the spittoon unit would vary its position relatively to the patients chair in dependence on the pivoted position of the dental unit, and since the part of the dental unit necessary for fitting the spittoon unit would further prejudice easy movement.
  • the main object of the present invention is to provide a dental treatment assembly in which the aforesaid disadvantages are minimized or eliminated.
  • a dental treatment assembly comprising a patients chair and a dental treatment unit supported by the chair which is mounted on a base for adjustment in a generally vertical direction relatively to the base, the treatment unit including,
  • a housing disposed on one side of and connected to the patient's chair, the housing presenting an upper surface
  • a support arm mounted at one end on that part of the upper surface of the housing which is remote from the base of the chair for pivotal arcuate movement in a substantially horizontal plane relatively to the housing
  • a dental spittoon unit mounted on that part of the upper surface of the housing which is nearer the base of the chair.
  • the support arm is articulated to a vertical pivot bearing so that it is situated so far above the upper side of the dental unit that the mouth rinsing tumbler and the spittoon dish or funnel are accommodated therebelow.
  • the vertical pivot bearing By arranging the vertical pivot bearing on the dental unit it self, when the hand appliance housing unit is pivoted horizontally, it is simply necessary to pivot the support arm instead of the entire heavy dental unit. Furthermore, the dental unit always now retains its position relatively to the patients chair, so that it can be provided with a spittoon unit. Owing to the arrangement of the vertical pivot bearing for the horizontal jib near that side wall of the dental unit which is adjacent the foot end of the patients chair, the greater part of the cross-section of the dental unit is freed for the fittings of the spittoon unit, such as a heating device for water, the automatic system of the mouth rinsing tumbler filling device, settling vessel for the suction installation, etc.
  • the spittoon unit such as a heating device for water, the automatic system of the mouth rinsing tumbler filling device, settling vessel for the suction installation, etc.
  • the dental unit can also be made to extend so far towards the head end of the patients chair (with an elongated, narrow crosssection) that the part equipped with the spittoon unit can easily be reached by the patient.
  • the feature whereby the support arm at its underside is articulated to the vertical pivot bearing at such a distance above the upper side of the dental unit that the mouth tumbler and the spittoon dish or funnel are accommodated below it, has the advantage that the support arm can be pivoted over the dental unit when not in use. In this inoperative position, dental unit and support arm occupy only a relatively small space so that they constitute a very small obstacle e.g. when cleaning the rooms in which the apparatus is situated.
  • the vertical pivot bearing arranged on the upper surface of the dental unit, for the horizontal support arm, to be com structed in such a manner that the support arm can be pivoted through at least 50 to each side of a substantially vertical axis passing through the center of the bearing from its inoperative position above the dental unit in order that the dental unit can be used selectively supported on the left-side or right-side of the chair both for right-handed users and left-handed users.
  • a further advantageous development of the subject of the invention consists in that at the side wall of the dental unit which is adjacent the head end of the patients chair, housings are provided for a strong-suction nozzle and a saliva extractor nozzle. If these nozzles are arranged in this region they are particularly comfortably within the reach of the dental nurse, who usually operates these.
  • the support for the dental unit on the patients chair comprises an elongate support member in the form of a guide rail which extends parallel to the longitudinal axis ofthe patients chair and along which the dental unit is guided so as to be displaceable and lockable in desired positions.
  • FIG. 1 shows a dental treatment assembly in an inoperative position
  • FIG. 2 shows the dental assembly of FIG. 1 in an operative position.
  • l designates the patients chair which comprises a head part 2, a back rest 3, a seat part 4, a foot part 5, a base 6 which supports the chair on the floor, and a vertically adjustable base part 7 which is connected to the seat part 4, and a parallelogram arm 8 which connects the two parts 6 and 7 to one another.
  • the dot-dash 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 I.
  • a support arm 12 is connected at one end through the agency of a rigid casing 14 on that part of the upper surface I] of the housing which is remote from the base of the chair 6 for pivotal arcuate movement in a substantially horizontal plane about a substantially vertical axis 15.
  • the connection of the arm 12 is adjacent the end 13 of the housing, which end 13 is nearer the foot part of the patient's chair.
  • the arm 12 is connected to the casing 14 for pivotal upward and downward movement about a substantially horizontal axis in the form of a pin 16.
  • the dental hand appliances are supported on the other, free end of the arm 12, the housings l7 and 18 for a turbine handpiece 19 and a micromotor handpiece 20 inset into the end face 21 of the arm 12, and a dental syringe 22 rests in a housing 23 fixed to the upper surface of the arm I).
  • a dental instrument tray 24 is supported in a manner to be described below the hand appliances 19, 20, 22.
  • a stirrup-shaped handle 25 is also mounted on the free end of the arm 12 between the syringe 22 and the handpieees 19, 20.
  • That part of the upper surface I] of the housing which is nearer the chair base 6 Le. adjacent the head part 2 of the patients chair 1 is constructed as a spittoon unit and carries at the upper surface 11 a removable spittoon bowl 26, a mouth rinsing tumbler 27 and a mouth rinsing tumbler filling device 28. Also arranged at the narrow end 29 of the dental unit 10 are operating pushbuttons 30 (for the tumbler filling device, operation of the syringe and the like) and below these operating pushbuttons 30 a strong-suction nozzle 31 and a saliva extractor nozzle 32 are arranged removably in respective supports in a housing 33.
  • FIG. 2 an elongate support member in the form of a substantially horizontal guide rail 34 which extends parallel to the longitudinal axis 9 of the patients chair 1 is mounted on the vertically adjustable base part 7.
  • a carriage 35 supporting the dental unit is supported to be displaceable lengthwise of the chair (arrow 37) by means of bearings in the form of rollers 36 (for the sake of simplicity, only one roller is illustrated) and to be lockable by means of a releaseable locking device constituted by an electromagnetic brake 38.
  • FIG. 2 also shows the way in which the tray 24 situated below the hand appliances i9, and 22 is supported.
  • the tray 24 is supported by a counterbalanced arm assembly 39 including a parallelogram linkage which is disposed below the arm 12 and which at one of its ends is mounted for pivotal movement about two substantially horizontal axes 40 and 41 of the casing 14, the axes 40 and 41 being disposed one above the other.
  • the axes corresponding to the pivoting axes 40 and 4] at the tray-side end of the parallelogram arm 39 are designated as 42 and 43.
  • a substantially horizontal pivoting arm 44 Provided at the undersurface of the arm 12 is a recess 45 into which the arm 39 can be sunk over its entire length.
