United States Patent 3,386,766 DENTIST CHAIR COMBINATION WITH UTILITY SUPPORTING ATTACHMENT Joseph Gorelick, 594 Merrick Ave., East Meadow, N.Y. 11554 Filed Dec. 8, 1966, Ser. No. 600,217 7 Claims. (Cl. 297-192) ABSTRACT OF THE DISCLOSURE Chair for dentist for use, while operating on patient in reclining position, the chair being provided with special means supporting dentists working tools formerly supported on dental unit positioned on the side of patients chair opposite from the working position of dentist.

This invention relates to dental office equipment and relates more particularly to a chair assembly for use by the dentist and having supporting means therein for the high and low speed drills, the syringe for supplying air, water and combination thereof, and other equipment used by the dentist during the practice of both general dentistry and oral surgery.

It has been a common practice in the past to support these instruments of the dentist on a console on the side of the patients chair opposite from that at which the dentist stands during the performance of this operations. As a result, the dentist is constantly reaching over the patients body to pick up the drills, syringe and other instruments and, at the end of a given operation, the instrument must be returned to its support in the same fashion.

SUMMARY OF THE INVENTION In accordance with the present invention, the drill assembly and other instruments and equipment are mounted on the chair used by the dentist, the patient being disposed in a reclining or semi-reclining position on a lounge type of seat. The dental instrument and accessories are conspicuously absent from the patients view in the normal position opposite from which the dentist sits. The dentist seated on the novel chair of the present invention then performs his operations and has at his side all of the instruments and accessories which are instantly available without any extended reaching and particularly without reaching over the patients body which has an adverse psychological effect upon the patient or creating physical discomfort for himself.

It will be apparent from the foregoing that an important object of the invention is to place and support for convenient access the dentists instruments and accessories at his side where they belong and have them readily accesible from a semi-concealed location out of the normal line of vision of the patient. This utilizes the available area of the dentists office much more effectively than heretofore when the instruments were mounted on the patients chair or suspended menacingly on an ungainly pedestal with which the patient or the doctor frequently collided.

The significant improvement in the present invention lies in the fact that instruments regularly and repeatedly used are out of the way and to a large extent out of sight when the patient moves onto his reclining chair, thus avoiding accidental collisions. The favorable psychological effect upon the patient is marked. After the dentist draws his chair and equipment supported thereby to the side of the patients chair and sits down, he has the instruments readily available at the proper height and location, i.e., in fixed relationship to the dentist while working, and when the work with a given piece of apparatus is finished ice it traverses a path of minimum distance back to its support. There is thus provided a fixed relationship of instruments to dentist during operative procedures and these instruments move along with bodily movement of the dentist.

In the drawings:

f FIG. 1 is a perspective view of the apparatus from the ront;

FIG. 2 is a broken plan view thereof;

FIG. 3 is a side elevation from the right hand side of the device;

FIG. 4 is a broken area elevation.

The stool 10 chosen for illustration in the drawing is of the swivel type and has a base 11 with radial legs 12, casters 13, a pedestal 14 leading upwardly to a cushioned seat 1-6. The stool has a back structure extending up wardly at the rear section of the seat and it includes a cushioned back rest 18 suitably supported such as by a flat bar 19 having a lower horizontal section 20 which is movable inwardly and outwardly of the chair seat to an adjusted, fixed position. The back rest is secured, as shown, to the bar by means of a stud 20 extending rearwardly therefrom and the back rest is secured by a nut in the nature of the handwheel 21. A bracket 22 is mounted in fixed relation near the upper end of the vertical back rest and has a hinged joint or elbow 24 at its outer end supporting one or more arms, shown in FIG. 3 as including a telescopic arm 26 provided with an extensible section 28 for swinging movement about the vertical pivot.

A second elbow 29 forming a vertical pivot supports a second arm 30 which carries a plurality of brackets 32, 34 and 36, the first of which supports a low speed drill 38, the second or high speed drill or air rotor 39 and the third a triplex syringe 40 for supplying air under pressure, water or a combination thereof. Conduits 44 and 45 extend from these drills to a box 46 housing a selector switch controlled by a push-pull rod 47. A control box 48 is mounted just below seat 16 and a flexible conduit 49 containing power lines and air and water pipes extend from a wall panel 50' to this control box. A conduit 52 extends from the syringe 40 to the control box for supplying water and air to the syringe and a conduit 54 from the control box furnishes water and air to the housing.

The pivoted arm structures 2630 extending from the bracket 22 is generally horizontal and is of a height equal substantially to the height of the working hand of the dentist during his operative procedure, which is usually about 26". This is about equal to the height of a patients head lying in a reclining position so that the instrument is brought to the patients mouth and returned to its support in one short, fluid motion. Operation of the drills is controlled by a movable foot switch 56 having conduits 58 leading to a fioor receptacle 59.

Instead of the two arms 26 and 30, one being of telescopic construction, shown in FIGS. 3 and 4, a single arm 60, shown in FIG. 2 may be provided. This, for convenience, maybe curved as shown at 61 and be pivotally joined at 62 to bracket 22 which in this instance is somewhat longer than bracket 22.

While there have been described herein what are at present considered preferred embodiments of the invention, it will be obvious to those skilled in the art that many modifications and changes may be made therein without departing from the essence of the invention. It is therefore to be understood that the exemplary embodiments are illustrative and not restrictive of the invention, the scope of which is defined in the appended claims, and that all modifications that come within the meaning and range of equivalency of the claims are intended to be included therein.

The embodiments of the invention in which an exclusive property, or. privilege is claimed are defined as fol lows:

1. The combination with a dentists stool having a wheeled base, a seat and a back assembly, of a dentists unit supported by said stool so as to be movable toward and away from a dental patients chair mounted in fixed relation on a floor, an arm structure mounted on said back assembly and extending generally horizontally therefrom on a plane generally coextensive with the hand of the dentist when in a working position which in turn is on about the same plane as the head of the dental patient sitting in a reclining position on said dental chair, said arm structure including a horizontal bracket secured in fixed relation on said back structure and an arm section extending outwardly therefrom and pivotally connected therewith, a plurality of supporting brackets carried on said arm section, a control box mounted below the stool seat and movable therewith and conduits leading therefrom to dental instruments mounted in said supporting brackets.

2. The structure of claim 1 wherein said arm section is curved.

3. The structure of claim 1 wherein there is a second arm between said arm structure and the horizontal bracket.

4. The structure of claim 3 wherein the second arm section is telescopic 5. The structure of claim 1 wherein a control box with a push-pull switch has conduits connected wi.h said dental instruments.

6. The structure of claim 1 wherein the arm structure is located at about the height of a dentists operating hand.

7. The structure of claim 1 wherein the arm structure is at a height to create a fixed relationship to the den ist while he is sitting during operating procedure regardless of what position he may be required to move to.
