Definitions
- the invention is concerned primarily with providing a stool for dentists and dental assistants to be used while working on or administering to dental patients seated in a dental operating chair, although many other uses are possible.
- Dentists and dental assistants normally stand while working on or administering to a patient in the dental chair.
- the necessity of bending over and peering into the mouth of a patient imposes considerable strain on the body and results in fatigue and often in muscular pains of one kind or another.
- Principal objects in the making of the present invention were to provide effective and comfortable support for the waist as the upper trunk of the body is cantilevered forwardly toward the patient from a seated position; to provide this in a manner adaptable to the body charac teristics of various users of the stool, to provide for easily and positively locking adjustable components in their adjusted positions; to enable a short person, usually the dental assistant, to sit comfortably and to maneuver effectively, even though his or her feet do not reach the floor when seated; and to provide all of the above with streamlined and pleasing appearance as well as compactness, ease of handling, and minimum spacial encumbrance.
- the curvature of the body rest largely conforms to that of the stool, and the mounting arrangement is preferably such that the rest may be adjusted more or less inwardly toward the vertical axis of the stool to accommodate thin as well as medium and stout individuals, such body rest retaining much of its cantilever arrangement with respect to the post even in its extreme positions of adjustment so that it will extend across the front of the waist of a person seated on the stool and give effective support when such person leans forwardly to take care of the dental work at hand.
- FIG. 1 represents an elevational View of the stool looking directly toward the back of the post which supports the body rest;
- FIG. 2 a top plan view, with a different adjustment of the body rest being indicated by broken lines;
- FIG. 3 a bottom plan view
- FIG. 4 a fragmentary view in vertical section taken on line 44 of FIG. 1 and drawn to a larger scale, showing one of the cam locks in its locked position;
- FIG. 5 a corresponding view, but showing the cam lock in its unlocked position.
- the stool comprises a circular seat 10 supported in stool fashion at the upper end of a post 11, which rises centrally from a base 13 and depends centrally from the seat as part of an extendible and retractable hydraulic assembly (not shown) mounted in such base.
- Base 13 is platform-like and hollow, being maneuverably supported by casters 14. There must be at least three castors for stability, as is quite apparent, but preferably there are five, so that, regardless of surface irregularities in the floor unevenness, there will always be at least a three-point support for the stool with consequent stability at all times during use.
- the platform character of this base providing a substantially unbroken expanse of supporting surface coupled with the fact that its diameter significantly exceeds that of the seat 10 so that its periphery extends outwardly beyond the periphery of the seat, enables a person seated on such seat to comfortably and effectively rest his or her feet off the floor when found desirable.
- a sleeve 15 extends down to the base 13 as a tube housing, where it is secured as by welding.
- a ring of oil-impregnated felt (not shown) wipes oil onto the surface of post 11 as it rises and descends relative thereto.
- an abdominal rest 17 is provided in upwardly spaced relationship with the seat. It is supported in what is essentially cantilever fashion from a post 18, which is preferably a broad and rigid bar or strip of some such material as steel or aluminum rising above the seat near the circumference thereof.
- Body rest 17 is of broad strip formation in the sense that it is wide but relatively elongate, so as to provide comfortable and effective support for the body at or near the waist. It and seat 10 are preferably cushioned with foam rubber or the like and upholstered with a washable plastic sheet material.
- rest 17 is adjustably positioned relative to post 18 so as to accommodate thin as well as stout persons.
- the rest is largely curved in conformity with the seat and is positioned so that its width extends vertically and so that its length extends horizontally in cantilever fashion from one side of the post.
- such body rest preferably has its opposite end portions deviating outwardly from the aforespecified curvature, the end portion 17a nearest the supporting post 18 advantageously being rectilinear or approximately so. Best results are had when the circularly curved intermediate portion of the rest subtends an angle of about
- rest 17 is: provided with a bracket arm 19, which extends from near the middle of such rest backwardly and outwardly along the back of one end portion of the rest, see particularly FIG. 2, and
- enemas is firmly secured to post 18 by suitable releasable fastening means, such as a unique cam lock 20 operable by hand lever 21 and constructed as shown in detail in FIGS. 4 and 5.
- post 18 is firmly but adjustably secured to the rest of the stool structure by means of a second cam lock 22, FIG. 1, operable by hand lever 23.
- cam lock 22 is illustrated in FIGS. 4 and 5, cam lock 20 is of the same type.
- a slotted receptacle 24, FIGS. 4 and 5 defines a throughway for slidably receiving post 18 (bracket arm 19 in the instance of cam lock 20).
- a cam 25 Extending across the interior of receptacle 24 and journaled in the lateral walls thereof is a cam 25 in the form of a rod whose cross section is circular, except for a sector face 26 which is preferably provided with a continuation in the form of a protuberant lip 27 having a terminal face 27a at substantially right angles thereto merging into the otherwise cylindrical periphery of the rod along a tangent.
- the lever arm or operating handle 23 (21 in the instance of cam lock 20) is fixed to one end of the cam rod 25 perpendicularly to the sector face 26 of such rod, so that, when such handle is turned up as shown in FIG. 1 (inwardly in the instance of handle 21 of cam lock 20) a curved portion of such rod exercises cam action against the opposing face of post 11 to frictionally lock it tightly against therewith opposing face portions of receptacle 24.
- Receptacle 24 of cam lock '22 is secured, as by welding, to the outer and upwardly turned end of a mounting bar 28, so that its throughway is disposed vertically for slidably receiving post 18, while the receptacle of cam lock 20 is similarly secured to the upper end of post 18 with its throughway disposed horizontally for slidably receiving bracket arm 19.
- Mounting bar 28 is secured, as by welding, to the upper end of post 11, and, in order to provide for independent swiveling movement of seat and body rest 17 relative to each other, an anti-friction bearing 29, has its upper race plate secured to the seat, as by bolts, and its lower race plate secured to mounting bar 28 and post 11, as by welding.
- the mechanism, indicated 32-34, 37, 41, and 42, FIG. 3, for raising seat 10, and coincidentally, body rest 17, is housed within hollow base 13 and is operated by a foot pedal 31 which projects a convenient distance beyond the outer periphery of the base, see FIGS. 1, 2, and 3, at a location that is preferably diametrically opposite one of the castors 14.
- a foot pedal 31 which projects a convenient distance beyond the outer periphery of the base, see FIGS. 1, 2, and 3, at a location that is preferably diametrically opposite one of the castors 14.
- the height of stool seat 10 is adjusted by pressing footpedal 31. It is not intended that there be a lifting of a person seated on the stool, but, rather, that there be a powered lifting of the stool seat 10 alone, since this is all that is necessary from a practical standpoint.
- the dentists or other person using the stool desires to alter his working position upwardly, he need merely step on the foot-pedal while raising his body.
- the stool seat will closely follow until the pedal is released, whereupon a sitting position can be resumed without ever having taken eyes or hands from the work in progress.
- a stool particularly adapted for use by dentists and dental assistants while working on dental patients, comprising, in combination: a maneuverable base structure; a substantially circular seat mounted on said base structure; a supporting post extending upwardly from and in adjacency to the periphery of said seat; means mounting said post for revolution about the periphery of said seat; a trunk rest of strip-like, substantially curved configuration mounted cantilever fashion on said post and having its length extending substantially horizontally therefrom; and means adjustably interconnecting said trunk rest and said post for lateral movement of the former relative to the latter, so that the degree of cantilever extension of said trunk' rest from said post can be adjusted as desired.
- the stool of claim 1 wherein the means adjustably connecting the trunk rest and the post includes a bracket arm extending from the back of the trunk rest and extending longitudinally along approximately one-half of its length, and locking means for fastening the bracket arm to the post in various positions of adjustment.
- the stool of claim 1 wherein the base structure is of platform formation extending peripherally outwardly beyond the periphery of the seat and providing a substantially unbroken expanse of supporting surface for the feet of the user, and wherein the seat is supported on said base structure by a center post extending upwardly therefrom.
- the stool of claim 1 further including means interconnecting the seat and the base structure for rotation of said seat relative to said base.
