p Application ledvctober 25, 1927." Serial No. 228,514.`

rllhis is a continuation in. part of my oopending application Serial No. 117,893, liled' June 23, 1928, which will b'e abandoned in favor of this application.

My invention relates to beds, particularly to such structures adapted for use by invalids; and amon the objects of the invention are to provi e a structure which may be built as a part or placed as a unit upon the bed of ordinary construction or other suitable support and which will embody a complete sectional supporting structure -for the mattress and operating mechanism for the sections so arranged that they may be readily and conveniently placed in various relative positions best adapted to care for the comfort of the occupant.: To provide op- -erating mechanism for the various sections of the structure which is simple in construction, convenient to operate and so arranged that the body and thigh supporting sections may be raised relative to the central or seat section, and, if desired, the thigh section positively returned to its normal position simultaneously With respect to the body section: 'llo provide supporting means for the outer end of the driving shaft of the operating mechanism adapted to be variously -positioned relative to its support.: To provide an improved structure to which the fabric for supporting the mattress, etc. may be. attached, the structure being so arranged as to avoid open gaps between the various 4sections in manipulating the structure in which the bedding would be caught and possibly torn or cut; and to provide a structure in which the parts to which the sup- .porting fabric is attached are so arranged that upon elevating'the thigh and leg sections relative to the seat section the fabric` is placed `under an increased tension.

The invention consists inthe novel constructions, arrangements and devices to be hereinafter described and claimed Vfor carrying out the above stated objects and such sectional view taken on the line 5--5 of Fig. 2, said Fig. 5 showing an end elevational view of the parts illustrated in Fig. 4; Fig. 6 is aY detail perspective view of a fragmentary portion of the seat section and one of the parts pivoted thereto; Fig. 7 is a perspective view of one of the fabric supporting and tensioning members carried by the leg section; Fig. 8 is a detail view of one end of the frame with a supporting bearing for the outer end of the operating rod and means for adjustably securing the bearing to the frame; Fig. 9 is a side view of Fig. 8, with the end of the frame member in section; Fig. 10 is a plan view of a bedstead with parts broken out, and showing modification of certain parts of my invention; Fig. 11 is an elevational view of Fig. 10; Fig. 12 is an enlarged view of a section of the supporting structure illustrating means for adjustably securing the supporting bearing of the outer end of the operating rod, and Fig. 13 is a side vievtr of Fig. 12, showing the end supporting member in section.

In the drawings similar numerals of reference indicate corresponding parts of the different views, and referring to tlie same, l() and l1 denote the head and foot res ectively and 12 the side rails of a bed, of w lich the present invention may be made as a part, or as a self-contained independent structure of which 13, preferably of angle bars. formsv a base frame adapted to rest upon the side rails of the bed or other suitable support, and may be secured thereto in any suitable manner.

IThe sectional frame includes a seat section 14, body section 15, thigh section 16 and leg section 17, it being understood that in referring to the body, thigh and leg sections in the claims, the' terms member or members may be used in place of section or sections las desired. The seat section includes angle members 18, having their vertical angles or Webs 18a secured to the inner face of the sides of the basa frame 13, as by rivets 19, said meinbers 18 being disposed so that their horizontal angles 181 extend inwardly toward each other. The side members of the body and thigh supporting sections are preferably Aformed of angle bars 20, the pivotal connection between said sect-ions and the seat section being best shown in Fig. 6. rlhe vertical angles 20a are pivotally attached to the vertical angles or Webs of the seat section 18, as by rivets or bolts 21, the horizontal angles of bars 20 being cut back or relieved so that the angle bars 20 may freely swing relative to the angle members 18. The horizontal angles 18b extend under the horizontal angles 20b and their ends are curved at 18 which are so arranged that they will at all times be close to the extremity of the horizontal angle 2()b when the angle bar 20 is swung relative to the angle members 18. A side plate 22 may be attached as best shown in Fig. 2, to the vertical web or angles of the members 18, as by rivets 23, so as to provide an unbroken continuous surface at the sidesI of the sectional frame.

The le section 17 is also preferably formed of ang e bars, and its side frame members 24 at their pivotal ends are provided with angle members 25, such as shown in Fig. 7. These members are positioned at the inner and lower sides of the angles of the side members 24 and are firmly secured thereto by rivets 26. The members 25 being) secured to the vertical angle of ars 20 by bolts or rivets 27. The extending ends of the horizontal angles of members 25 are curved at 25, said curved ortions and the adjacent ends 28 of the horizontal angles of the side members 20 of the thigh section be' ing so arranged that the gaps -between the horizontal angles of the side members of the thi h and leg sections are closed at all times.

'Fhe fabric that supports the matress is stretched over the sectional frame and secured to the horizontal angles of the side and end angle bars of the various sections of the pivoted frame, as by helicals 29, shown in Fig. 1, at the pivot connections of the seat, thigh and leg sections.

It is desirable to prevent any substantial sagging of the mattress supporting fabric at the seat section when the body, thigh and leg sections are raised relative to the seat section. As best shown in Fig. 6, the horizontal angle of member 18 ofthe seat section is perforated at 18, portion at 18", and the attached member of one of the pivoted sections at 20. In like manner the angle member shown in Fig. 7 is perforated at 25", and the perforations 18e and 26b are preferably located directly over the axes of the pivots of the various sections. It will be observed, therefore, that the fabric is stretched tightly over the sectional frame when the latter is in normal or flat position and will remain more tightly over the seat and the-body and thigh sections when the two latter are elevated relative to the former, then if secured to the horizontal angle of the frame members of the different sections at the sides of the cut out portions of said angles to provide for free swinging movement of the pivoted sections.- To further avoid sagging it will be apparent that since members 25 are carried by the leg section, that when the leg and thigh sections are pivotally v the gap closing curved' moved from the normal or flat to an elevated position, the distance between erforations 18 and 25b will be increased an thus cause the fabric to be placed under an increased tension, and thereby further reduce sagging at the seat section..

The mechanism for' raising and lowering the body, thigh and leg sections relative to the seat section will now be described,

transverse shafts

30 and 31 are journaled 1n Suit able bearings 32 carried by the base frame 13. A bell-crank lever 33 is fixed to the shaft 30, and arm 33El thereof bein connected bya link 34 to the body section 15 and the other arm 33b thereof being pivotally connected to a tubular member 35. A rod 36 externally threaded at its inner end extends into the tubular member 35 and has threaded engagement with a nut 35* secured therein about midway of the t'ubular member. The outer 'end of the operating rod 36 extends through a laterally disposed slot 13* in the vertical angle of the end bar of the base frame 13 and an adjustable bearing 37 (see Figs. 8 and 9), which is formed to furnish a surface at right angles to the axis of said rod, vand is adjustabl secured to the vertical angle of said end fiar, as by bolts 37. A collar 38 is fixed on the rod 36 at the outer side of the bearing 37 to prevent inwardly axial movement of the rod 36 in the bearing 37, and a collar 38*l is also secured to the rod 36, which contacts with the bearing to prevent outwardly axial movement of the rod 36', the contacting faces of the

collars

38 and 38"l being formed so as to provide for slight tilting of the rod 36 in its bearing, the intention being to, provide means so that the outer end of the rod 36 may be shipped (see dotted outline, Fig. 1) to avoid interfering parts, such as .the uprghts at the head or foot of a bedstead. A. crank 39 is detachably connected with the outer end of the rod 36 and made operative by a pin 39fl in a corresponding slotl in the crank hub. A lever 40 is fixed on the shaft 30 and its swinging end connected by a link 41 to the other side of the body section 15. It will now be apparent that when the crank 39 is turned in one direction the body section 15 may be raised and when the crank is turned in'the opposite direction said section may be lowered.

The mechanism for raising and lowering the thigh section 16 includes

levers

42 and 43 both fixed to the shaft 31 and having their swinging ends connected by links 44 to section 16. A lever 45 is loosely mounted-on the shaft 31 adjacent the lever 42, axial movement of the lever 45 on the shaft being prevented by a fixed collar 46. The lever 45 is connected to the arm 33b of the bellcrank lever 33 by a pull and thrust rod 47 which is made in two sections connected by a turn-buckle 48 to provide for notarse hubs of the

levers

42 and 45 have laterally projecting 'co-erigaging

lugs

49 and 50 respectively.` The operating mechanism is so constructedA and arranged that a substantial gap is present between the yco-engaging laces of the

lugs

49 and 50 when the

sections

15, 16 and 17 Aare in their normal or iat position on the basaframe 1.3. The posi-- tion of lever 42, when the sections are in their normal flat position is shown in dottedlines in Fig. 4, in such case-the meeting tace of lug 49 is at 'dotted Yline 49u and the meeting lace ot lug is at dotted line 50a, the lost motion gap these meeting aces. It will now be apparent that upon turning the crank 39 in the proper direction the bell-crank 33 will be turned anti-clockwise resulting in immediate raising or liftingof section 15. As the vertical arm 33h ot the bell-crank swings anti-clockwise 'the lever 45 is' ulledclockwise and upon the lost

motion etween lugs

49 and 50 being taken up by the aceof the lng 50 ot the lever 45 engaging the lace oi the vlug 49 ol the lever 42 the shalt 31 begins to rotate cloclrviise which causes the

levers

42 and 43 to raise the section 16. When the parts are in position shown in F ig. 2 the meeting line or tace between the contacting

lugs

49 and 50 is at the line 50i shown in llig. 4. lt will thus be apparent that the section 15 may first' be partially raised independently of the

sections

16 and 17 upon the section l5vf being raised to a predetermined extent, the sections l16 and 17 thereafter are raised simultaneously therewith; said predetermined entent being regulated by the length or" the pull and thrust rod 47. n the construction shown levers 338L and 40 that connect the operating mechanism with the body section 15 are longer than

levers

42 and 43 that are operatively connected with the thigh section 16 and it is, therefore, apparent that 'the body section may be moved faster than the thigh section.

l preferably provide means for holding the thigh section 16 in an elevated position if desired while the body section is being returned to its normal position and this same means may also be employed lor raising and lowering the thigh section 15 independently of the body section. The aforesaid means for accomplishing these results include a lever 51 lreely rotatable on the shaft 31 adjacent the lever 43, arial movement or" the lever 51 on the shalt away from the lever 43 being prevented by a collar 52. The meeting glaces oir thelevers 43 and 51 are provided with laterally projecting

lugs

53 and 54 respectively which have ico-engaging laces. ln lfig. 1 the lng 54 is in its normal position, that is to say, the osition it must occupy when sections-l5 an 17 ,are

being the space between in their normal or'at position. Since the

sections

16 and 17 are shown in partially elevated position there is a gap 54a between the

lugs

54 and 53, as the lug 54 remains stationary while

sections

16 and 17 are .ele- 'vated through the pull and thrust rod 47. The mechanism for turning' the lever 51 on its shaft includes a 'crank 55, tubular member 56 and rod 57. 'lhe outer end ot said rod 57 extends through a bearing 57a in the vertical angle of the end `bar of the base .y

frame 13, which is formed to furnish a surfaceat right angles to the axis or" rod 57, collars 57 b being lixed on the rod 57 at each side i of the bearing to the rod 57 in the faces of the collars 57h being formed so as to provide for slight tilting ot the rod 57 in the bearing, said mechanism operates in the same manner as the means attached to the vertical arm of the bell-crank lever 33 prevent axial movement of earing 57a, the contacting f heretofore described. 'Referring to li`ig1`4 it will be noted that a substantial gap is pro'- vided on the underside between the

lugs

49 and 50. By referring tollig. 1, it will ,now be appa-rent that upon turning the crank 55 in the proper direction the lever 51 will turn clockwise on the shaft 31 and the lug 54 will move to close the gap 54a and engage the lug 53 of the lever 43 and further turning of the crank 55 will cause the thigh sect-ion 16 to be raised and raisingoi" the .section may be continued until the under or lower face of the lug 49 (see Fig. 4) engages the lace of the lug 50. When the thigh section 16 is raised by turning the l crank 39, it will be apparent that the lug 53 will travel away from the lug 54 thereby increasing the length ot the gap 54a between the adjacent faces on the top side of said lugs. 1f it is desired to hold or maintain the thigh section in an elevated. position while the body section is lowered, it is only necessary to turnthe crank 55 so that the lever 51- will be moved to close the gap between the

lugs

53 and 54.

' As heretofore explained the leg section 17 is pivotally connected tothe swinging end of the thigh section lll. As the thigh section is raised the leg section tends to assume a position more nearly vertical. l have found that the leg and thigh sections under gravity alone do not always return to the normal or flat position on the base frame and in my present invention l have provided means for insuring, il desired, positive return oil the leg and thigh supporting sections to the normal position when the body section is returned to its normal position.. The means i'or accomplishing there-v sult just mentioned includes a two-positioned member 59 (see Fig. 4) which is in the forni of a pawl and is pivotally attached to a depending ortion of the lever 42. (lhe member 59 as a toe 60 adapted to be engaged by the underside of the lug 50 of the lever 45. The member 59 is rovided with a spring pressed plunger 61 a apted to snap into either one of the recesses 62. The member 59 as shown in full lines in Fig. 4 is in its operative position. The member being in its inoperative position whenf-it is in its second position as indicatedby'dotted lines in Fig. 4. It will be a parent from the foregoing description an working of the operative mechanism that, when the crank 39 is turned so as to move the bell-crank lever 33 in a clockwise direction to lower the body section 15, the lever will be thrust.

in an antlclockwise direction and, assuming the member 59 is in its operative position, the under side of the lug will presently engage the toe of the pawl and thereaftervresult-in the lever 42 being forced in an anti-clockwise direction thus insuring positive returnof the thigh land leg section to the normal position.

As the vertical angle of the base frame 13 extends upwardly a base for the free end of the leg section to ride upon is lacking and to remedy this defect short sections of angle bars 63, with their. horizontal angle extending inwardly and flush with the top of the base frame are secured to the latter at each side of said frame by rivets 64, thereby providing flat bases for the free end of the leg section toAA ride upon as its pivoted end is raised and lowered.

Figs.`10, 11, 12 and 13 illustrate a modified form in which the base frame 13 of Figs.

1 and 2 is omitted and only the body section 15a of the sectional frame is shown, the latter being pivotedly attached to brackets secured directly to the bed rails 12, in a manner fully described in my co-pending application Serial No. 585,940. Said brackets may be firmly but detachably secured to thebed rails, as by clamp-straps 66, formed of tiatsteel with a hole near each end, near which they are bent to right angles. Near the base of the brackets are openings through which the clamp-straps 61 pass, and are bent around the base of the brackets and the bed rails and drawn by bolts, not shown,.but fully described in my copending application previously mentioned. The mechanism for raising and lowering the body section 15a is similar to that previously described in connection with Figs. 1 and 2, except that only the body section is shown and the outer end of the operatin rod 36'L is carried b v somewhat different (gl porting bearing 68 adapted to be attached to beds without marring them when the base frame 13 is not used; the end portions of said bearing being formed to fit ythe outer and lower sides of the angle bar 69 at or near the end of the bedstead, whichv in the present case is the bar to which the bed fabric is attached, and is firmly secured thereto, as by etachable sup-- clamp straps 70, bent around the supporting bearing 68 having angular portions 68 an the angle bar 69 fitting therein and drawn by bolts 7 Land nuts 72. The central or bearing portion 68 is formed to resent surfaces at right an les to the axis of) the operating rod. Said rotis provided 4with collars 73 secured thereto at each side of the bearing to prevent axial movement of the rod in the bearing. The contacting faces of said collars are formed to provide for slight tilting of the rod in its bearing,-and is operated by the crank 39 as vpreviously described in connection with crank 39 and operating rod 36, shown in Figs. 1 and 2.
