My invention relates to an adjustable chair. ,1" The object of my invention is to provide s, a chair that is adjustable with respect to the back and collapsible to a compact position for storage, shipping or the like.

' A still further object of my invention is to provide an adjustable foot rest for-the chair detachably arranged.

A still further object of my invention to provide a'chair that may be adjusted by the occupant while seated therein and also the foot restthereof v A still further object of my invention is to provide a chair that the back and foot rest will adjust sufficient to function 'as'a couch or the like. 1

A still further object of my invention is to provide a chair adaptable for'use in 'hospitals or the like, the said chair to be pro; vided with'rollers. Q

These and other objects wilh'l 'ereiii'be more-fully'explaine'd, reference being had to the accompanying drawings forminga part of this specification in which like characters will apply to like parts in the difierent views, and in which:

Fig. 1 is a side view of the chair positioned for the normal seating posture.

Fig. 2 is a rear view of the chair.

Fig. 3 is a vertical section thru the chair.

Fig. 4 is a side view of the chair collapsed for storage or transportation.

Fig. 5 is a side view of the foot rest'with the chair fragmentarily shown.

Fig. 6 is a side View of the foot rest aligned with the 'plane of the chair, the chair fragmentarily shown.

Fig. 7 is a plan'view of the foot rest as shown in Fig. 6 with the chair removed.

My invention herein disclosed is a collapsible chair and foot rest conibinedconsisting in detail of side rails 1 rearwardly extending and slanting downward as rear legs for the chair; attached to the upper edges thereof and connecting the same is a plurality of slats 2 spaced apart functioning'as a seat, the said rails are pivotally' connected to the front legs 3 by arod 4 extending from one'to the other, the said legs are further-braced bya bar 5 positioned .in close proximity to the lower ends thereof, and a secondbar 6 :spaced downward from the front slat of the seat-communicating with the-ends'ofrails' 1 andfbetweenuthe bars the legs of the foot rest will. engage as later ClSClibed.' I Y 4:; 1' To= the upper end. of the: frontu legs are pivotally' -conn'ected an arm element 7'z'as at A,.the rear. endofi the saidarins beingaea'rried by a rod 8. extending across the-back oflthechair and trunnioned thereon thru the medium-of bearings 9"thatware securedto their respective slats 10: of the back; the said slats-being connected by I a. cross barull spaced downward from the upper ends thereof, the lower ends being connected-by a rod 12 that pivotally engages on the side rails lifrom which point-the back'may be rocked to a desired an le rearward :thru the-medium of a pair of standards 13, the upper ends ofwhich engage on the said rod 8' while-the lower ends are rigidly carried by another rod 14, the last said rod pivotally engaged at each end by an arm 15 that is secured to 'a'shaft 16 rotatably' arranged and trunnioned at its outer ends on the side rails 1 near the rear extremities thereof, the saidrodbeing rotated by a crank 17 by which means a reciprocating movement is imparted to the standards 13 carrying with themthe back of the chair to a desired angle rearwardfthe arms 7 are likewise drawn rearward causing the front legs to rock simultaneous with the movement.

To overcome excess friction that would occur by the rocking movement'of the front legs, I have secured to the lower end of each, a roller 18 and to the rearend of rails 1 a pastor 19, the latter being the means to turnthe chair While moving the same from place to place.

In Fig. 3 is shown a rearward slant of the back greater than that shown in Fig. 1 which is accomplished by a rearward rock of lever 17 as shown by dotted lines B in Fig. 1 showing the extreme downward movement of the standard'13, carrying the'back therewith. p

To nearly align the back with the seat as clear the slot of obstruction when the down ward position of the back is desired? In Fig. 3 is shown a disk element having an arm 24 tangentially extending'the're from, the disk is trunnionedv on shafti 16 adjacent the inside of side rails 1, the arms' of the-disks slidably engagedn a notchepositioned ,ineach end of a 'cross rail. 25 that is carried bythe 'said side-rails. To avoidthe upward :movement ofthe'arms, a .pin

26 is firmly afiixedto their respective rails,

by which means 'the said idiscfli's retained against rotation but free to move longitudinally when-shaft 16 iswmOVedu WandEin slot :27, the latter; movement being required whenythe chair is folded as Sh0WI1!iIl Fig.,4:, in which operation-the-ends ofthe rods -12 will be guided rearward: in their 1' respective slots 28, by which means the backwillirock forward resting on the seat i :while i the :leg s 3xand their=respective arms 7 -.will;foldr'simultaneously-therewith, all of which will bezin parallelism and in close proximityv :to the side rails as shown.inFig.=4. L A Radially -extending;from the said disk 23 and integral therewithis a shoulder128' as showninFig. 3, and-on which the outer end extensionsof rod: 14- willrest supporting one angular-position of the back'iwhile another position is supported'by seating the said end portions in depressions 5 29; formed in the peripheral edges of-the disks by which means rotation of the shaft 16 is prevented when pressure rearwardly is imposed on the said backfi I I When the ends of the rod 14 seat as above described, radial movement thereof is required with respect to the disk and'toipermit such movement a slot 30 is arranged in each arm in which the endsof said rod 14 will slidably engage but is restricted against inward movement by reason of engagement 011 the periphery of the disk as driven therearound by the crank 17 which imparts rotation to shaft 16. r

In Figs. 5, 6, and 7 is shown a-foot rest for the chair attachable and adjustable in its connection with the chair and also adjustable to accommodate for the :desired position of the occupant. a

The component parts thereof consist of a pair of arms 31 connected at the rear ends by a cleat 32, the said=cleat having a lip D upwardly extendingto snu lv engage between the slats of the chair bottom avoiding longitudinal movement thereof while the arms cantilever on bar 6 as carrying means for the outer ortion of the structure. Rockably arranged and pendantly carried by the arms is a platform 33 on which to rest the feet of the occupant while seated in the chair.
