the invention consists of a series of panels attached by hinging mechanisms or of a pliable material with the ability to be held in shape and changed back to the original shape . in its simplest form , the device consists of a rotatable backboard member 1 attached to a hinged section 2 parallel or near parallel to the bed surface 3 . section 4 and 5 are hinged wing units attached to section 2 . for accoustical considerations , 1 could be shaped in a semi - circle . part 6 is a rotational axis for member 1 and member 2 . in fig2 articulates with dial 7 which in turn is contiguous with section 1 . the articulation facet is 11 . at the other end of the axle 6 , section bracket 8 attaches to member 2 . collar or tube 9 allows 6 to rotate within . rigid member 12 is attached to tube 9 and this is affixed by means of clamp or series of clamps 13 to bed frame structure . as illustrated in fig2 member 1 rotates independently with dial 7 while member 2 rotates independently with articulation 11 by moving with axle 6 separated from dial 7 by gasket or lubricated washers 10 . this rotational ability would be required for on - the - side patient positions while semi - circular or circular shapes would allow easier accoustical sealing . fig3 shows the stored position with panels 4 , 2 , 5 and 1 within the same plane and parallel to the wall . wings 4 and 5 retracted and 2 elevated all within the same plane as 1 . fig3 again shows section 4 and 5 retracted while member 2 is elevated and all of these are within the same plane as 1 . the backboard consists of a large circle . it would not need to be rotatable and less hardware would be necessary . in a simple form the wings 4 and 5 and panel 2 would be moved manually into position with wings 4 and 5 being affixed by velcro straps to bed sides or mattress , thus completing a four - walled seal ( actually three walls 1 , 4 and 5 and a ceiling 2 ). deployment of 4 and 5 as walls has accoustical value while at the same time lending support to the ceiling member 2 . since 2 may be equipped with a tv , tape deck , clock , oxygen hook - up , etc . affixed into modular cutouts within 2 and possibly 4 and 5 , the entire structure could become too heavy for easy manual manipulation . this weight problem can be solved in fully equipped models by means of passive hand - manipulated or active motor - driven hydraulics affixed to 2 , 4 and 5 . fig4 shows hydraulic power pack 14 with arms 15 affixed to 2 , 4 and 5 . fig5 shows the deployment of 2 , 4 and 5 with power pack 14 affixed to semi - circle 1 . panels 1 , 2 , 4 and 5 have modular cutouts to accommodate tv , radio , speakers , drawer space , telephone hook - ups , oxygen hook - ups , and electrical outlets . the invention brings the writing desk , storage and and entertainment center close to the patient and affords the patient privacy in using it . the exact location of the modular cutouts would be by patent preference , though they could be standardized for production purposes . fig6 depicts members 4 , 5 and 2 bent back on themselves to show an overextension of foam or other accoustical material such that when 4 and 5 are deployed in their normal position in the direction of the arrows they are sealed along the hinged seam . modular cutouts would be made through the accoustical materials . the writing board with tissue tray , etc ., could also be used for hospital meals or breakfast - in - bed in the home situation . the best method would be to have the desk surface hinged from the central member 2 at the foot direction edge in two folds , one for simply uncovering the central entertainment panel 2 and the second to deploy to a desk or eating surface . in fig7 a we show deployment to position number 1 . section 17 and 18 , fig7 a and 7b are stored flat against the panel 2 and can be deployed in position 1 for just the added accoustical and private effect of adding a foot direction wall or into position 2 for a table desk with section 18 deployed down to bed level on resting arms 19 . arms 19 should be adjustable with stand screw 20 for various patient heights while section 18 can be kept basically parallel to bed surface 3 by moving in direction of double straight arrows of fig7 b . container sections for pens , pencils , writing paper , etc ., swing down from wings 4 and 5 and are hinged centrally on the wings to accommodate for sideway tilting of the assembly for the &# 34 ; on the side &# 34 ; patients . shelf 21 is the same width as or slightly larger than container section 22 so that it accommodates same in folded position . outside surface of section 17 when folded back to section 2 affords a writing surface for persons who cannot sit up . the use of velcro fasteners would be most useful for tacking up these foldable units .
an adjustable writing desk , storage and entertainment center apparatus attachable to the head of a bed to provide bedridden patients with easy access to writing materials , a writing surface and privacy in viewing television and listening to radio and recorded music by enclosing the patient &# 39 ; s head and upper torso within the apparatus which is equipped with sound insulation .
