Adjustable orthopedic lounger

Claim 1

An orthopedic lounger comprising: a floor engaging base; a supporting frame mounted atop the base and having a front end, a back end, opposed side wall members, a top surface, and a bottom surface; a seat portion constituting a unitary structure and stationarily mounted to said support frame in a position spaced vertically thereabove, said seat having a front end and a back end; a leg rest portion having a front end and a back end, said back end of said leg rest portion disposed adjacent said front end of said seat portion; hinge means connecting said back end of said leg rest portion to said front end of said seat portion for relative pivotal movement in a vertical plane pivotally about a horizontal transverse axis; an integral head and back rest portion having a top end and a bottom end, said bottom end disposed adjacent said back end of said seat portion; hinge means connecting the adjoining edges of said back rest bottom end to said back end for relative pivotal movement on an axis parallel to the pivotal connection of said leg rest to said seat portion; one of said side wall members of said supporting frame being provided with a first arcuate slot adjacent the front end thereof and a second arcuate slot adjacent the back end thereof; a reversible electrically operated motor having a shaft extending out of one end thereof; a pair of axially spaced apart concentrically disposed toothed sprocket wheels disposed on said motor shaft; a first horizontal disposed transversely extending shaft carried rotatably by said base adjacent said front end wall thereof; a second horizontal disposed transversely extending shaft carried rotatably by said base adjacent said back end wall thereof; said first shaft having a toothed sprocket wheel affixed concentrically thereto; a first endless sprocket chain trained about said first sprocket wheel and said first mentioned of said motor sprocket wheels; an elongated operating lever arm having one end affixed to said first shaft with said lever arm projecting radially outwardly therefrom; a guide pin extending outwardly of said arm substantially normal thereto and received in said first arcuate slot of said supporting frame side wall member such that operation of said motor will effect reciprocal movement of said guide pin through said slot; a sprocket wheel affixed concentrically to said second shaft; a second endless sprocket chain trained about said second sprocket wheel and said second mentioned motor sprocket wheel for drivingly interconnecting the same; a second elongated operating lever arm having one end affixed to said second shaft with said arm projecting radially outwardly therefrom; a second guide pin affixed to said second lever arm and projecting outwardly therefrom substantially normal thereto and adapted to be freely received in said second arcuate slot of said supporting frame side wall member such that energization of said motor will effect the reciprocal movement of said second guide pin through said second slot; a guide member connected to said back rest and operable to effect said pivotal movement thereof between a position lying in the plane of the seat and a position disposed upright relative thereto as well as to any selected position therebetween; said back rest guide member having one end affixed to said back rest with said guide member projecting outwardly therefrom and having the opposite end thereof operatively connected to second guide pin with movement of said guide pin in said arcuate slot effecting the pivotal swinging movement of said back rest relative to said seat; a guide member connected to said leg rest portion and operative in a manner to effect the pivotal movement thereof between a position lying substantially in the plane of said seat and a position disposed downwardly therefrom as well as to any selected position therebetween; said leg rest guide member has one end affixed to said leg rest with the opposite end projecting outwardly therefrom and operatively connected to said first guide pin with movement of said guide pin effecting the pivotal movement of said leg rest relative to said seat; an electrical control switch including a pair of electrical push button switches adapted to be manually held in an ''''on'''' position with release of the push buttons effecting the return thereof to their normal ''''off'''' positions, a first one of said push buttons effecting the clockwise rotation of said motor with the second one of said push buttons effecting the counterclockwise rotation of said motor, permitting an individual to selectively simultaneously adjust said back rest and said leg rest relative to said seat; and an integral sheet like member overlying the top surfaces of said back rest portion, said seat portion and said leg rest portion to provide a smooth continuous cover layer thereover.
