Thisjnvention relates tclwheel chairs; and aims primarily is provide a.,nove1and 'practicalf wheel cliair which canbe readil 'collapsed'iintoasmalr compact? mass; which can also" readily" be con: verted in to fabedor' table; and whichfican be readily raised or. lowered.
The above aswell as .otheriobiects; will become apparentinthe description below, wherein char actfers" of reference refer to .like numbered parts on the accompanyirig drawir'i gs'. Referring to the for the purpose.of. illustration only, and-it is neitherintendednor desired to limit the invention necessarily to the specific details of construction shown excepting insofar as they may be deemed essential to the invention.
Referring briefly to thedrawings, Fig. 1 is a perspective view. of the chair. Fig. 2 is a side view of the chair. Fig. 3 is a side view of the chair showing the same in lowered condition and also with theback and leg members folded into a table.
Fig. 4 is a plan view of Fig. 3. Fig. 5 is a fragmentary plan viewof the detail 'of the steering mechanism of the chair. Fig, 6 is a sectional view taken on the line 6-5 of Fig. 2.
Fig. '7 is a plan view of. the link per se joining the back of the chair with the seat when the back is upright and supporting the back of the chair when the latter is substantially horizontal.
. Fig. 8 is a sectional view taken on theline 8--8 of Fig. 2, showing another detailof the steering mechanism. 1
Fig. 9 is a fragmentary sideview of one of the w chair wheels and its related structure.
Fig. 10 is a sectional view taken on the line Ill-40 of Fig. 9. i i erring in detail to the drawings, the numeral ll indicates the chair seat, at the fourfcorner edges of whichbrackets l2 and I3 are secured. From each of the brackets l2,:a. rigid member 14 i is pivotally supported on one end, and these members extend downward in a forward direc- 1 tion. Similarly, from eachbracket IS a member 15 is pivotally supported and extends downward in a rearward direction. On each side of the.
chair, the member I4 is pivoted to the member l5 at the midpoints of both on. a pin I6. Also pivoted to the pin i6 is a downwardly extending upright member I1, and a cross-member. l8 is secured to both uprights I1 to brace the same,
Casters l9 are provided at the four corners of the chair, in the yokes of which fupright stems are rotatably mountedwhich extend upward.

are pivoted to the front and rear casters respec-" tively, in such manner that they are and always remain parallel with the members l4 and I5 as is obvious. On each side of the chair, a vertical rack bar .2515 secured to the chairbottom. Just inside the members M and [5 on each side of the chair, a pinion 21 is rigid on theshaft 28, the
latter being an integral extension of the pins I6;in other words, the pins iii are on the exe tremities of the shaft 28. A crank 29 is:secured to one or both of the pins IS. The extremities of the members l4 and I5 are slotted at. 30 for the obvious purpose of permitting these members to be collapsed in lazy-tongs fashion.
It is now apparent that the chair seat ll may be'readily raised or lowered by turning the crank 25. A pair of axially aligned slat-like members 3| are axially pivoted to the brackets l3, and by means of ears 32 the leg boards 33 are piv otally supported in a hanging position from the slats 3|. Foot rests 34 are pivotally supported on a rod 36 and limit stops are provided in the I2 in an obvious manner, and is maintained in upright position by linked brackets 38; the normal position of the seat floack 31 ispreferably slightly tilted rearward, not shown. The brackets 38 then prevent the back 31 from falling backward.
. To fold the back 31 down upon the seat II, it
need simplyibe folded about its hinge into the position shown in Fig. 2 in broken lines. The
The brackets 38 comprise hollow tubular piv ots 4| having the two ,arms or links 42 and 43 i thereof pivotally secured thereto, as shown in Fig. 7. The lower end of each bracket I2 has a pin 44 extending outward therefrom, and each side of the seat II has also a, pin 45 extending therefrom near the rear thereof. The arm 43 has a hole in the extremity thereof in which the 'pin 45 registers normally, when the seat back 37 is upright. To fold the seat outward as shown in Fig. 3, the link 43 is disengaged from the pin 45, and when molded substantially horizontally, the hollow; pivot Al is passed over the pin 44, so that the arm 42 serves as a brace to the horizontal chair back and the arm 43 hangs loosely.
To support the foot boards 33 in horizontal po- 7 sition, on each bracket l3 a. link is pivotally' secured, and normally hangs loosely downward. Pins 41 project from the upper side edges of the boards 33, and when the latter are horizontal the hole 49 in the outer end of the link 46 is passed over the pin 41 on each side, thus bracing the horizontal foot boards. Thus, as shown in Fig. 3, a substantially horizoptal bed surface is provided by the chair back 31, the seat I l, and the foot boards 33. H
To enalb le steering' ofthe chair, apost 50 is rotatably supported in a bracket 5| on the seat I I.
The base of this post is rigidon the end of an arm 52 in' whose end a link 53 is pivoted. A cross arnr54 has'its extremities pivoted to ears or lugs 55 on the casterfyokes I 9 of.the front wheels. A crank or handle 5611s pivotally joined at 15 to .the top of the post 5B,where'by the post is turned to actuate the steering mechanism in' an obviou's'rnanner. Whenthe chair isfolded openings in the ends of which (and which is in the form of a yoke) the shaft 28 extends, maintains the rack 26 in contact with the pinion 21.
Icla imt q. H.
