March 21, 1933. D. KING INVALIDS 01mm Filed April 9, 1952 Patented Mar. 21, 1933 "PATENT oF-FicE DELLA KING, or LOUISVILLE, KENTUCKY INvALIDs CHAIR h Application filed April 9,

. This invention relates to improvements in chairs, and particularly toa chairdesigned for the use and convenience of invalids and sick persons, the main; object of the inven- .5 tion'being toprovide a "chair whichrmay be easily rolled from place to place, which provides] a, comfortable seat, and comfortable rest for the feet, back andhead and arms ofthe person or patient, and which embodiesarm rests;either one or both of which may be moved rearwardly to an out of the way position, so that the'sick person or invalid may be moved from a bed or couch on the chair, or vice versa, without interference or obstruction fromthe arm rests.

-A further object of the invention is to provide a chair of the character described having hinged arm rests which are designed to be latchedsecurely in normal position and which may be swung to an inoperativeposition, whenever'desire'd, inrear'of the back of the chair,rwhich positiomthey will retain until positively'moved to operative position. 7. The inventionconsists of the features of construction, combination and arrangement of'parts, hereinafter :fully described and claimed, reference being had tothe accom- "panying drawing, in which )Fig. 1 is a perspective view of a rolling chair embodying my invention, showing the arm rests in normalposition. h

In carrying my invention into practice, I provide a chair 1 of suitable general formation and comprising a seat 2, supporting legs 3, rungs 4 connecting and bracing the legs, and a back 5 comprising side uprights'6 and intermediate uprights 7, suitably fastened at their lower ends to the seat 2 and connected at their upper ends by a cross bar 8. The back 5 and its bar 8 are of suitable versely of and laterally beyond the upright.

formation and height to provide'comfortable back and head; rest portions'for the occupant of the chair. .The front legs of the chair have attached thereto a footrest 9, of broad, comfortable type, arranged at a suitable ele- 55. vation and which may be adjustable or fixed, as desired, and to the upper rear portion of ther seat backg5 is applieda handlebar 10 whereby the chair may beeasily and con veniently rolled and otherwise manipulated by an operator or attendant, The lower ends of the legs3 are provided with suitable roller supports 11: which may be of caster wheel type, as shown in the present instance, or of ball-bearing roller type, so that the chair may be easily and xuniversallydrawnj or f pushed from place to place; 1

The chair is also provided at each siderwith an arm rest 12 which, inaccordance with m invention, maybe of suitable height and of a lengthtoextend substantially-the full or a greater part of the distance between the uprights 6 and the forward edge-of the

seat

2, 7 so that such :arm rests, when in operative position will provide firm and substantial arm rests or supports. Each of these rests, as shown, comprises top and bottom, longitudinalibars 13 and 14, front and

rear end bars

15 and 16, rungs 17 connecting the bars '13 and 14, and arm supports 18 which may be or not of upholstered type. Each armrest is hingedat its rear edge to theadjacent upright 6 to swing rearwardlynfroma normal vertical operative position-{as shown in Fig.1, rearwardly to a folded positiontrans- 1.3 versely ofand at the rear of the seatback5 and parallel therewith asshownin dotted [lines in Fig. 4. To this end, each arm restl8 is provided upon each of. its bars Band 14 with a hinge leaf 19, extending longitudi- .nally thereof or parallel therewith and pivotally connected, as at20,by a pivot' pin 1 or pintel to a hinge member 21 fixed? to the adjacent back upright 6 'and proj ectingtrans Thenprightsfi have enlarged or widened lower ends 22'spaced inwardly from the adjacent side edge of the seat 2 to permit the arm rests when disposed in normal position to rest securely on the seat, the widened lower end of the upright 6 providing a strengthened support and abutment for the arm rest to which the latter is hinged and which forms a stop which braces the arm rest firmly against inwardmovement. Each arm rest is provided at its forward end with a spring-actuated snap latch or bolt 23 to automatically interlock with a keeper 24 on the seat 2 when said arm rest is moved into operative position, thereby locking the arm rest against casual outward movement.

It will be observed that the ends of the position rearwardly to the dotted line position '12 in rear of the seat back 5, to which either or both of-the arm rests may be swung, thus providing for the positioning of the arm rests in working position so as to be strongly supported by the chairseat and back or to be'moved rearwardly to a position in which they are entirely out of the way and the seat 2 at the sidesof the chair left open or without obstruction at the sides, so that the.,chair may be brought alongside a couch or bed and a'person or patient moved easily and comfortably laterally from the bed to the chair or from the chair tothe bed, as will be readily understood. The

hinge members

19 and 21 may be united attheir hinged con.-

nection 20 in such manner that a suilicient amountof friction or 'bindingpressure between the hinge leaf will be caused to prevent the freed arm rests from swinging looselysand to adapt them to maintain their folded back'position until positively moved forward again to operative position.

From the foregoing description, taken in connection with the drawing, the construction, mode of use and advantages of my novel and improved convalescents or invalids chair willbe readily understood, and it will be seen that a chair of this character is provided which is simple of construction, de-

What I claim is i i 1. A chair having a seat, a seat back including side members set inward from the side edges of the seat and forming stops, side arms hinged on fixed pivots to swing to a forward operative position above and at the sides of the seatand against-'said' sto s and to a rearward inoperative position behind the seat back, and a latch for fixing each side arm in its operative position to the seat.

2. 'A chair having a seat, a seat back having portions forming stops, side arms hinged on fixed pivots to the seat back to swing to a forwardoperative position above and at the sides of the seat and against said stops and to a rearward inoperative position behind the seat back, a keeper on the seat at eachside of the chair, and a spring actuated latch on the free end of 'each side arm to engageand interlock with the keeper at-its-s'ide' ot the seat.

3.- A chair having a seat, a seat'back-provided with side uprights having widened lower ends forming stops securedto theseat andispaced inwardly from'the side edges of the latter, side arms hinged on fixedpivots to said side uprights to swing to 'a forward operative position above the sides of the-seat and against said stopsand to a rearward-inoperative position behind the seat back, and a'latch for fixing each side arm in its operative position to theseat.

4. A chair having a seat, a --seat back provided with side uprights having widened lower ends forming stops secured'tothe-seat x and spaced inwardly from the sideedgesof the latter, side arms hinged on fixed pivots to said side uprights to swing in a forward operative position above the 'sidesofthe seat and-against said stopsand to a rearward inoperative position behind the seat back, a

keeper on the seat at each side of the chair, ,7

and a spring-actuated latch-on-the freeend ofeach side armto engage and interlock with the keeper atits sideof the seat.

signed to form a comfortable support for the body andlimbs of the patient, to permit the patient to be easily drawn or rolled from place to place, and which allows the patient to s be' transferred from the chair'to a bed or couch .orfrom a bed or couch to the chair without great exertion either to the patient or-nurseor other attendant or possibility of injuryxto the patient. While the structure disclosed is preferred, it wil1,of course, be

understood that changes in the form, an

'rangementand details of construction of the parts may be made within the scope of the appended claims, without departing'from the spiritor sacrificing any. of the advantages of the invention.
