Definitions

  • a working tool for dentists has a stand located at the side of the patients chair and having an expectorating base carrying a cup or funnel for spitting and possibly a mouth spray, as well as a holder for hand carried pieces, such as sprayers and suction hand pieces.
  • the invention is characterized in that the stand has a vertical axis about which the expectorating base swings and that the base also has a vertical axis about which an arm swings.
  • the arm has at its: free end a holder for v the hand carried pieces.
  • hand carried pieces such as sprayers and suction hand carried pieces.
  • a dentist's tool is known in the art, having a stand which can be adapted sidewise to a patients chair and is connected with a casing for an expectorating base which is swingable about a vertical axis.
  • This arrangement makes it possible to swing away the base without moving the stand or the instrument carrier swingably connected with a supporting arm extending over the stand and set in a position suitable for treatment.
  • the swinging of the base makes it possible on the one hand to approach the patient closely and on the other hand, to easily bring the spitting cup and the drinking glass to the patient.
  • the hand carried pieces located at the front of the base are firmly fixed thereto.
  • An object of the present invention is to eliminate the drawbacks of existing constructions by providing an arrangement of the expectorating base with its hand carried pieces in such manner that they can be easily reached in every working position by the dentist without any assistance, while retaining the advantage of undisturbed work resulting from the swinging of the tool.
  • the stand with a vertical axis upon which the base is swung and to provide the base also with a vertical'axis about which swings an arm carrying upon its free end a holder for the hand carried pieces.
  • the connecting member between the two vertical axis is constructed as a substantially upright parallelogram carrier swingable in a vertical plane.
  • the length of the parallelogram carrier preferably corresponds to about the height of the stand. If the axle bearing of the base is placed at about the lower edge of the stand and if the axle bearing for the arm carrying the holder is located at the free end of the parallelogram carrier, then a comparatively largestroke is provided for adjustment in height to the patients chair, and there is an easy removal possibility as well as an increase in stretching width in the longitudinal direction of the chair as well.
  • FIG. 1 is a perspective view showing the device of the present invention.
  • FIG. 2 is a top view showing the attachment of the stand to the patientschair. I
  • FIG. 3 is a partial perspective view showing the attaching means of the holder.
  • FIG. 4 is a rear view of the patients chair.
  • FIG. 1 shows a dental working device with a stand I which can be brought to the side of a patients chair.
  • the stand carries a swinging arm 2 upon which an instrument holding device 3 is arranged so that the hand carried pieces can be easily directed into the mouth of a patient sitting upon the chair.
  • the arm 2 can be swung about a vertical axis 4, 'while the instrument holding unit and the depositing plate 5 can be swung jointly about a common vertical axis 6'.
  • the plate 5 is located below the arm 2 and is connected with it by a carrying arm.
  • An expectorating base 7 is located at the front side surface of the stand 1 and is swingable abouta further vertical axis 8.
  • the head portion of the base 7 has a spittoon cup 9, a mouth spray 10 as well as a holder 11, for hand carried pieces 12.
  • Theholder 11 is carried by an arm 13 which is swingable about an axis 14.
  • Thevertical axis 14 coincides with the central axis of the cup
  • the connectingmember between the bearing for the axis 14 and the bearing for the axis 8 is a substantially upright parallelogram carrier 15 swingable in a vertical plane.
  • the length of the parallelogram carrier 15 corresponds substantially to the height of the stand 1.
  • the lower end of the parallelogram carrier 15 is linked to a support 16 which can be swung about the vertical axis 8.
  • FIG. 1 shows by broken lines a location of the base 7 in a swung out position corresponding to about one half of its stroke.
  • a carrier 20 is provided to adapt the stand 1 to the part of the patients chair which is movable in height.
  • FIG. 2 shows in top view the location of the working tool relatively to the patients chair '21.
  • the stand I is attached by a carrier 20 to the part of patients chair which is adjustable in height.
  • the base 7 is showninv FIG. :2 in a position in which it is swung away from the patients chair. .
  • the holder 11 with the arm 13 are swung toward the patients chair.
  • the holder 11 consists of several holding claws 22, 23 located next to each other in an elongated block 30, whereby the block 30 is connected with the arm- 13 by a holding member 24 upon the front side located away from the patients chair.
  • the arm 13 and the block 30 have the shape of the numeral 7, whereby the block 30 constitutes the upper transverse part of this numeral.
  • the block 30 "can be easily removed from the member 24.
  • the holding member 24 is provided with a pin or flange (not shown) which connects it with the arm 13 while providing a small slit.
  • the block 30 carries a metal sheet 25 provided with an opening (not shown) corresponding to the diameter of the pin extending between the holding member 24 and the arm 13.
  • the shape of the holding member 24 corresponds to that of the block 30, so that when the parts are joined the block 30 and the member 24 form a unitary structure.
  • a holding member corresponding to that of member 24 is provided upon the rear surface of the back rest of the patients chair 21.
  • this holding member 31 carries a block 32 consisting of two claw carrying parts and is similar to the block 30.
  • the hand carried pieces are not shown in FIGS. 2, 3 and 4.
  • the holders of the block 32 are so arranged that the hand carried pieces fitting between the claws can be conveniently grasped. It is, therefore, also possible to provide the block not upon the rear surface of the chair back but upon a side surface of the back of the chair 21 directed toward the base 7.
  • a dental unit comprising a stand fitting on the side of a patients chair, an expectorating base, means connecting said base with said stand and having a first vertical axis, said base being swingable about said first vertical axis; an arm having one end mounted upon said base and swingable about a second vertical axis and a holder for dental instruments carried by the other end of said arm.
  • a dental unit in accordance with claim 1, wherein said holder comprises a plurality of parallel claw-like members joined side by side to form an elongated block.
  • a dental unit in accordance with claim 1, comprising another arm mounted upon said stand and swingable about another vertical axis, and an instrument carrier carried by said other arm.
  • a dental unit in accordance with claim 1 for use with a patients chair having a portion adjustable in height, said tool having means connecting said stand with said chair portion.
