CANTON; QHIO, CORPORATION OI OHIO- f g AUXILIARY 'Blns'r Application filed July 18,

auxiliary childs foot rest may be used as required, thereby avoiding the necessity of hav: ing a. separate small dental chair for childrens and'short persons" use;

11 The-objects of the present improvements include theprovisionin a dental chair of an auxiliary childs step or platform and'foot rest, conveniently combined an adults step-or platform and foot rest, the auxiliary step or platform and foot rest being adapted to be extended into operative position and withdrawn into inoperative and unobstructive position, byanea'sy manual operation,

These objects are, attained thepresent "2'0 improvementsas will-hereinafter be set; forth indetailand claimed; 7 V priefeflfde ibo'dirnent of the improve ments is illustrated inthe' accompanying drawingsi forming; part hereof, in which tive position, the auxiliary foot rest folded back inoperative "and IlQl'l QbSllI'llC tive position;

Fig. 4:, a fragmentary'sectional View as in the direction of the arrows H, Fig. 2.

Similar numerals refer vto similar parts throughout the several views.

The dental chair indicated generally'at 10,

a is provided with laterally spaced angled foot rest

side frame bars

11 and 11" secured at their upper ends to the seat 12 and extending forwardly and downwardly therefrom to the

apexes

13 and 13 from which the outer beam rtions 14 and 14 extend horizontally forward and are pivotally connected at their outer ends with an angularly adjustable adults foot rest extension 15. I

The side bar beam portions 14; and 14' support for substantially half their outer span,

Figs. land 3, the outer surface of thepanel 19' is a continuation of the horizontal outer surface ofth'e platform 16, and t'he longi tudinal-ly extending. edges of the panel 19 overlap fandarefsupported by the side bar beam portions 14 and 14", and the outer surface 0f, the 558120. extends: between the up perinclined portions- 22. and 22' of the side ars. v

Theangled platform member lS, in the 1 the side bar's are preferably connected by a Figure Lisa 'perspectiveview .ofa dental. chair showing theadults foot rest opera-fr position illustrated in Fig. '3,'; has its front side angled inwardly and its rear side angled outwardly, andflugs 26 extend outwardly from the apex Q21 offthe platform member 18 at the rear-side thereof, and the lugs 26 are pivotally connected withthe outer end- 27 of auxiliary platform member 28, arranged to be extended and withdrawn between the

g p r inclinedtportions

22 and 22 of the side ars.

I Theauxiliary platform niember 28 is pro- Yided' at its side edges with inwardly and downwardly extending flanges 29 which tere Ininate at130,,afsi1ificient distance from the adjacent face 31 of an inwardly-and down wardly extending flange 32 provided at the. outer lateral edge of the platform 28, to form hooknotchesldd v n V- 3 the p 'thdra-wn positionv of the auxiliary: foot ,rest illustrated inFig, 3,.the side flanges 29" restuponlaterallyextending lugs'34 provided on' each of the side bars, and ride upon the same when the platform member 18 is swung outwardly about the pivotal connection at 17, until the extended position illustrated in Fig. 4 is reached, when the notches 33 engage the lugs 34 to maintain the auxiliary foot rest in the extended position.

For withdrawing the auxiliary foot rest, the auxiliary platform member 28 is moved upwardly to disengage the notches 33 from the lugs 34 and the combined platform member 18 is swung inwardly to resume the posi- 1. In a dental chair and the like includ ing a seathaving a foot rest frame, a foot rest platform. having a normally horizontally disposed lower panel and an upper panel extending angularly from the lower panel and normally inclined toward the seat, the foot rest platformfbeing pivotally mounted on the foot rest frame at the outer edge of the lower panel, andmeans for holding the foot rest platform when moved about its pivotal mounting to a position in which the upper panel is inclined outwardly away from the seat and is spaced above the normal horizontal position of, the lower panel 2.

In a dental chair and the like;including a seat having a foot rest frame, a foot rest platform having a normally horizontally disposed lower panel and an upper panel extending angularlv from the lowerpanel and normally inclined toward the'seat,the foot rest platform being pivotally mounted on the foot rest frame at the outer edge of the lower panel, an auxiliary platform member pivotally connected at one end to the foot rest platform at the inner edge of the lower panel for holding the foot: rest platform when moved about its pivotal mounting to a position in which the upper panel is inclined outwardly away from the seat and is spaced above the normally horizontal position of the lower panel, and means on the foot rest frame for releasably maintaining theauxiliary platform member in a substantially horizontal position when the upper panel is in its outwardly inclined position.

In testimony that I claim the above, I have hereunto subscribed m name.
