1 Claim; 3 Drawing Figures 1 ADJUSTABLE ORTHOPEDIC LOUNGER BACKGROUND OF THE INVENTION 1. Field of the Invention This invention relates generally to chairs of the lounging type and more particularly to a novel lounger developed to provide desirable orthopedic support and adjustable between a straight position and an upright position as well as to any angle therebetween.

2. Description of the Prior Art Many individuals throughout the world are afflicted with various types of back problems or leg problems, such as slipped discs and the like, with these individuals often finding it difficult and painful when attempting to sit or relax comfortably in chairs, couches, and other types of furniture as conventionally used by individuals not having such problems. However, due to the supporting characteristics and normal angles of such conventional furniture, such individuals normally cannot rest on the same without suffering some type of pain, this affecting the individuals social activities since the individual is not able to entertain other individuals for any length of time in an enjoyable manner.

While prior art devices have attempted in one way or another to provide comfortable seating for such individuals in a manner to minimize the pain, such have not met with commercial success or been fully accepted by the consuming public due to such devices suffering from one or more disadvantages such as being overly complex in operation, difficult to repair and maintain, costly to purchase, being of a large and bulky size so as to not be aesthetically pleasing and fit into a normal room of furniture, and the like.

SUMMARY OF THE INVENTION The present invention recognizes the need of individuals suffering from back trouble and the like and provides a novel solution thereto in the form of an orthopedic lounger specifically designed to fit the decor of normal conventional home furnishings and which provides suitable head, back, seat and leg rests which are adjustable as selected by the individual while resting on the lounger in a manner to provide the most desirable positions of the lounger for a comfortable, relaxing and enjoyable relief of pain of the individual.

It is a feature of the present invention to provide an orthopedic lounger selectably adjustable by an individual resting thereon between a straight position and an upright position and any angle therebetween.

A further feature of the present invention provides an orthopedic lounger of a compact size and configuration adapted to readily fit into the decor and size of conventional home furnishings.

Yet still a further feature of the present invention provides an orthopedic lounger wherein the adjustment is accomplished by remote control conveniently situated in the frame of the chair in a position to be readily operated by the fingertips of one of the individuals hands while the individual is seated or laying'on the lounger in the intended manner.

Among further features and provisions of the present invention is the provision of an orthopedic lounger which is relatively simple in its construction and which therefore may be readily manufactured at a relatively low cost and by simple manufacturing methods in comparison to presently available orthopedic devices; one which is possessed of few parts and therefore is unlikely to get out of order; one which is rugged and durable and which therefore may be guaranteed by the manufacturer to withstand many years of intended usage; one which is easy to use and reliable and efficient in operation; one which is aesthetically pleasing and refined in appearance; and one which is otherwise well adapted to perform the services required of it.

Other features and advantages of this invention will be apparent during the course of the following descriptron.

The floor engaging base 11 is preferably of a hollow box-like rectangular configuration having a front end wall surface 21, a back end wall surface 22, opposed side wall surfaces 23, a bottom floor engaging surface 24, and a top surface 25, the surfaces defining interiorly thereof a hollow compartment 26. Mounted on top surface 25 is the supporting frame 12 which is of a general rectangular configuration having a front edge 31, a back edge 32, opposed side wall members 33, a bottom surface 34, and a top surface 35. Disposed in one of the side wall members 33 adjacent front end 31 is an arcuate slot 36, with there being disposed in the same side wall surface adjacent back edge 32 a second arcuate slot 37.

Mounted in compartment 26 is anelectric motor 41 having a shaft 42 which is provided with a pair of axially spaced apart concentrically disposed

toothed sprocket wheels

43 and 44, the motor being connected by a suitable electrical cord 45 terminating in an electrical plug 46 adapted to be plugged into a conventional household receptacle 47 for supplying power to the motor. The motor 41 is electrically reversible and is provided with a control panel 48 mounted in one of the frame side wall members 33 and which includes thereon suitable push button switches 51 and 52 with switch 51 energizing the motor in a clockwise direction and with switch 52 energizing the motor in a counterclockwise direction, it being understood that the motor remains energized as long as therespective switch is manually held in the on position with release of the switch effecting the de-energization of the motor.

Extending horizontally transversely between base side wall surfaces 23 adjacent front'end wall 21 near top wall surface 25 is shaft 55 which is journaled for rotation between the side wall surfaces and which has affixed thereon a toothed sprocket 56 which is connected by an endless sprocket chain 57 to motor sprocket 42 for simultaneous operation therewith. Spaced from sprocket 56 on shaft 55 is lever arm 58 which projects radially outwardly from the shaft and terminates at an opposite end wherein there is affixed thereto a guide pin 59 which projects outwardly therefrom in a direction parallel to the shaft 55 and is engaged in arcuate slot 36 for guided supportive movement therealong.

Similarly, extending horizontally transversely between base side wall surfaces 23 adjacent base end wall surface 22 adjacent top wall surface 25 is a shaft 61 journaled for rotation between the side surfaces and having a toothed sprocket wheel 62 affixed thereon which is coupled to motor sprocket wheel 44 by means of endless sprocket chain 63. Spaced from sprocket 62 is lever arm 64 having one end affixed on shaft 61 with the lever arm projecting radially outwardly therefrom and terminating a distance therefrom with there being provided at the terminal end thereof a guide pin 65 projecting outwardly therefrom parallel to shaft 61 and adapted to be supportively guidingly engaged in arcuate slot 37 of frame side wall member 33.

The seat portion 13 is comprised of a rectangularly shaped cushion 71 supported by members 72 in a stationary position above supporting frame 12, the cushion having a front end 73 and a back end 74. The leg rest portion 14 is comprised ofa substantially rectangularly shaped cushion 75 supported by member 76 adjacent seat portion front end 73 with member 76 projecting downwardly from the cushion and having an aperture extending therethrough which is received on guide pin 59 such that movement of the guide pin effects the simultaneous movement of the cushion 75 between a downward projecting position and a straight position or any angle therebetween, the bottom edge of cushion 75 adjacent cushion 71 being hingedly connected thereto by transversely extending hinge member 77. The integral head and back rest portion is comprised of a somewhat bowed rectangularly shaped cushion 78 which is supported adjacent seat back end 74 by a member 79 which projects outwardly from the cushion to be pivotally joined with guide pin 65 for pivotal movement therewith, the top edge of cushion 78 adjacent the top edge of seat cushion 71 being hingedly connected thereto by hinge 80 which projects transversely thereacross. It is to be understood that the

cushions

71, 75 and 78 are manufactured preferably of vinyl covered polyurethane foam of an appropriate density and thickness, and that the cushions include frame structural members to retain the general shape and rigidity thereof when an individual is resting thereon.

A covering sheet member 82 is provided which overlies the top surface of cushions 78, 71 and-75 for the comfort of the individual resting thereon as well as to improve the aesthetic appearance thereof as to covering the portions between adjacent cushions such as at

hinges

80 and 77. In operation an individual sits or lays on the orthopedic lounger 10, depending upon the associated positions of the cushions, after which the individual depresses either of the buttons 51 or 52 in a manner to activate the electric motor 41 to pivot cushion 78 relative to cushion 71 as well as to simultaneously pivot cushion relative to stationary cushion 71 until the selected positionof the lounger has been achieved, at which time the individual releases the previously depressed switch button which retains the cushions in the selected positions.

There is thus provided a novel orthopedic lounger adjustable between a straight position and an upright position or any angle therebetween for relief of pain of individuals resting thereon who suffer from back trouble, leg problems, and the like so that such individuals can relax in an enjoyable comfortable manner substantially free of pain and thus able to converse and enjoy company of other individuals in the home.
