BED R ATTACHMENT THEREFOR.
Application filed September 2, 1922. SeriaINmSSEQ-GO.
My invention relates to beds, the object being to provide means whereby the posture of the occupant of the oed may be changed without undue strain or annoyance, and in the construction hcrmcatter (ascribed, which may be varied without departing from the'spirit of my invention. v
In the drawings, Figure l is a plan View of a bed with my improvements attached, engthwise central portion broken out iuce the width oi the drawing; Fig. 2 is a side cl onal view of Fig. 1; Fig. 3 an enlarged side view of the incasenient and power mechanism, with the front side oi the incasement cut away to better illustrate working parts; Fig. 4 is a cross sece tional view on line -ll oi Fig. 3; Fig. 5 is a sectional view on line of Fig. 2; Fig. 0 is an end view of the side rail in section with the supporting bracket in place; Fig. 7 is a section oi chains for connecting the two of levers with provision for adjusting their length, in which the ring is shown in section and Fig. 8 is an enlarged modified central section of Fig. 2.
In the drawings, similar, numerals of reference indicate corresponding parts in the different views, and, referring to the same, 1 and 2 denote the head andfoot respectively and 3 the side rails of a bed. Firmly secured to and near the ends of the side rails are bars st and 5, thus forming a supporting frame for the usual bed fabric, which is not shown as it is not a part of the present invention.
lwl'ounted upon the in brackets 6, formed with a lease side rails are support- 7 adapted to rest upon the top of the rails. the outeieside of these rails the brackets turn upward with holes 8 near their top, from wiich the top slopes toward each end. At the inner-side of the rails and near the ends of the brackets the latterare turned downward to form supports 9, and the central part is formed to rest against the vertical angle oi the ails thereby forming a brace 10 against the tension incident to the weight upon the fabric. At the inner-side of the rails sections of the brackets are turned up.- wa-rd with holes 11 thereinv positioned. to correspond with holes 8, Extending across and supported in these holes are screws 12, and threaded thereon are sleeves 13 with flanges 14: extending downward with their ends 15 resting upon the base of the supporting brackets, thereby preventing a revoluble or rocking movement of the sleeves; The object of these screws and sleeves is to form adjustable bearings to conform to the width of the jointed frame as compared with that ofthe bed on which it is used.
These brackets are firmly, but preferably detachablysecured to the rails, as by clampstraps 16, formed of flat steel with ahole at each end near which they are bent to right angles, and in securing the brackets the clamp-straps are passed through openings 16 of the upwardly extending portion of the brackets, bent over the base of the latter, around the side rails and drawn, as by screws or bolts 17, thereby firmly securing the brackets in place. It is obvious that these brackets may be modified and adapted to furnish pivoted support for-a single frame member as well as that herein described Mounted upon sleeves 13 are angle, bars 18 that form a central or-seat section, pivoted body or head and thigh or knee supporting members 19 and-2Urespectively, and to the latter is pivotally secured a: leg or foot supporting section 21, thereby forming a jointed frame to which the fabric 22 that supports. the mattress is attached (only small section shown), asby helicals 231 While the brackets shown are formed as stampings it is' obvious that they may be built up of parts, and", since the jointed frame furnishessupport for the fabric, and the pivotedlevers are supportably connected with thecentral or seat section it is apparent that the apparatus is self-contained and maybe secured to or supported by other means than bed rails. V
As it may be desired to use this jointed frame on old beds, without removing the bedt'abric therefrom, a pivoted spreader 24c has been devised, the number of which may be such as will meet requirements. Its ends pivoted in holes 25 at opposite sides oi'the frame with shoulders 26 to prevent the ends from slipping too far through. This spreader is held in an angular position, as by pins 27, so that as it contacts with the bed fabric the tendency would beto be carried upward out ofthe way, and at the same time give with the fabric and,
avoid a rigid resistanceto the weightofthe occupant of the bed.
If the jointed frame is used Without rethe other, or
moving the bed fabric, the leg section would drag upon it, also, beinterfered with by bar 5. To prevent this, brackets 28 to bridge said bar and support the leg section are provided. In the presentcase, they are'made of flat strips, being secured by clamp-st 'aps 16", described as 16, and misplacement atthe other end prevented by lugs 29 extending downward at each side of the rails. form an elevated base upon which the free end of the leg section rides as its pivoted end is raised and lowered by llllfilTIOVGlllBIll? of the thigh member. It is understood, of course, that if the bed fabric and bar 5 are not present these elevated brackets would not be required, as thelegsection in that,
case could rest and ride upon the rails, and that the connections of thebody and thigh members with the supporting brackets could be lowered accordingly, bringing the whole jointed frame closer to the rails.
L Pivotally supported in bearings 30 are shafts 31, and levers 32 and 33 which, while in the form of segments may be regarded as bell-crank levers, are lirmly secured thereto, as by hubs split between ears 3%): and drawn, as by bolts 35. These levers are sinnlarly formed, except that one of the levers 32 is adapted for use of two chains instead of one. The object of clamping these levers on the shafts is to permitadjusting their positions to conform to the width of the bed on which they are used. They are operatively connected with the body and thigh members of the jointed frame, asby links or pitmen 36, the latter being provided with shoulders inside the frame angle and held in place, as
by nuts 37, and in the presentcase the levers as shown are partly in segmental form, which affords a more uniform leverage and power at all positions, but it is apparent that otherforms of levers may readily be substituted. I
Chains 38 are passed over the segment of levers 33iand secured thereto, as by bolts 39, with a ring 40 at their free end, and chains 41 are secured to levers 32, as by bolts 42, passed beneath the segment with hoolrs 423 at their free ends, which in making connection is passed through the rings, returned to and hooked into one of the links, (see Fig. 7) thus forming adjustable operating connections between the levers, but it is obvious that other means to-form such connections may be substituted. The intention being to provide adjustment so that if desired one member of the jointed frame may be raised higher than that only one member be-raised, or provision may be made so that one member be raised faster than the other, which can be accomplished by lengthening or shortening either of the levers 32 or 33. As the levers are rigidly secured to shafts 31 it is apparent that only one connection between the two bent near both ends, one end These brackets 7 sets is necessary, the object of having a con nection on each side of the bed is, that if the latter is placed against a wall the connection on that side may be lengthened until inoperative and adjustment afforded through the exposed connection. Also, as it may be desired to retain the knee and foot sections in a raised position without that of the body member, levers 33 are provided with a ratchet or notches at, and pivotally secured to support 9 are pawls 45, which may be made inoperative by moving them to the opposite side of their pivots, and the one on the exposedside of the bed moved into contact when desired to retain the thigh member in a raised position.
An incasement formed by securing parts 46 and titogether, as by bolts 48, and an extension 50, channelled to make it more rigid, is secured to one end of the incasement, as by bolts 51, and to the free end of this extension is secured a hook 49 which, in the present case, is hooked onto bar l. and secured thereto, as by a hook bolt 52 through a-bolt hole 52 in the extension, or it may be attached in any suitable manner at either end of thebed. Brackets are secured to the rails, as by clamp-straps l6, described as 16. and revolubly supported by these brackets is an operating shaft 54, which extends across beneath the bed, passes through the upper part of the incaseluent and bearings that extend therefrom, the caps of which are a part of and extend from the top section 56 of the incasement, and are Se cured, as by bolts 57, This shaft furnishes part support for the incasement and is opcrated by crank 53,510 latter being detachable and may be applied to either end of the shaft, making it operative from either side of the bed. This eranl: m: I also be used to adjust the different sections of the jointed frame by applying it to either end of shafts 31, which are provided with pins 31 to make the crank operative.
lVithin the incasement, lengthwise of and extending from one end thereof is a threaded rod 59, which may be operatively connected to one of the levers 32, as by chain (50 passed beneath segment and secured thereto, as by bolt 61, or other suitable means. Mounted upon this threaded rod is a gear or nut 62, the hub of which is bored and threaded to mate the threads on the rod, and firmly secured on shaft 54-, as by pin 54 is a gear 63 adapted to drive gear (32, causing the latter to revolve around the threaded rod, thereby imparting to it an endwise reciprocating movement. Adjoining the hubs of gear or nut 62, the chamber of the in rascment is of the proper size to furnish suitable bearings or guides Get. for the threadi-ul rod, and extending therefrom toward each end chambers (35, 65 are large enough to furnish clearance for the free movement of the 1 ill) ingr the position rod said hearings on guides being. adapted: toprevent longitudinal movement of the gear or not on said rod. At the side of chamber ('and between the: parts 46 and 47 of the in casement, grooves 66 (see Fig. fl) are pro weed and through the rod 59 1s a pin 67 adapted to reciprocate with said rod with its ends riding; in the grooves thereby preventing the rod from revolving with the gear 62. Also, atthe open end of the chamber is a sterling box, 68, which may be filled with packing or other suitable material to absorb and prevent surplus lubricant from dripping, and is provided with a cap 69 secured in place, as by bolts 70, so the box may be cleaned out and repacked when desired.
