This invention relates to beds and more particularly to beds for invalids.
A primary object of the invention is to so construct a bed of this character that the bedstead itself and all parts carried thereby may be bodily raised and lowered and revolved and which may have the head or foot elevated one in relation to the other and supported in such position.
Another object of the invention is to provide such a bed so constructed as to be adjustable to support the occupant in various positions Without the necessity of disturbing him or removing him from the bed.
Another object of the invention is to so construct such a bed that the sections may be easily and quickly changed in their relation to each other by simple and efficient means without inconvenience to the patient and with little eiort on the part of the operator.
Another object is to provide a bed spring having an adjustable end section with counter-balanced locking means for holding it in adjusted position and so arranged that when the section is raised the locking means will automatically follow it and drop into locking engagement therewith when the section has reached its desired position. y
Another object of the invention is to cono struct a sectional bedspring having a lined central portion with sections hingedly connected therewith and provided withV lever controlled mechanism for raising and lowering the individual sections and provided with means for locking them in adjusted position.
In carrying out these objects, the invention is susceptible of a wide range of modification witliout departing from the spirit or sacrificing any of the advantages of the claimed invention; there being shown in the drawings for illustrative purposes a preferred and practical form, in which:
Figure 1 represents a perspective view of a bedstead constructed in accordance with this invention and having the end members of the spring one in raised and the other in lowered position;
Fig. 2 is a longitudinal section with the spring sections in alinelnent in the position assumed when the patient is to assume a recumbent position;
Fig. 3 is a similar View with the parts in the position shown in Fig. 1;
Fig. 4 is an enlarged longitudinal section taken through the central front portion of the bed and showing the :toot section of the spring adjusted to support the legs of the patient below the knee and in raised position;
Fig. 5 is a horizontal section taken on the G0 line 5-5 of Fig. 2.
Fig. 6 is an enlarged detail perspective view with parts broken oli showing the lever for raising the toot section and parts connected therewith. G5
In the embodiment illustrated the bedstead constituting this invention comprises a head hoard 1 and a foot board 2 connected by side bars 3 in the usual manner.
The head and foot board have corner posts 79 4 the lower portions of which7 below the side bars' 3, constitute the bed legs and these posts are equipped with longitudinally adjustable extensions held in adjusted position by set screws 6 so that when it is desired tolengthen 5 the legs at one end or the other of the bed, or both, the extensions 5 are projected and secured in position by the screws 6.
By providing these leg extensions it will bey obvious that either end of the bedstead maybe 59 bodily raised when desired so that it may be tilted to suit the convenience of the operator.
As shown the side bars 3 are provided about midway their length with depending bracket-like portions 8 to the lower edge of L) which is secured a cross board or platform 9. This cross beard 9 constitutes a thick slatlike member which supports between it and the spring 30,v presently to bedescribed, a plurality of coil springs 10. 93
Located beneath the cross plate or slat 9 and connected therewith is a stand 11 here shown of a length corresponding to the width of the bedstead or the length of the slat and which has the top 12 thereof hingedly con- C5 nected along one edge as shown at 13 to one edge of the board 9. This stand 11 is preferably mounted on casters 15 and the plate or top 12 is arranged between the top 14 proper of the stand and the slat 9 and has a bolt 16 v platform 14 of the stand llthebedsteadmay be bodily raised and lowered. E
Extending longitudinally of the stand and transversely of the bedstead is a.l roller or drum 2O around which isy designed to Vbe wound, two cables 2l'and22 which aresecuredy at one end to the cross bars 23 'of the supporting frame of thezplatforml4. These cables pass over guide `rollers 24 and'25 mounted in the stand -1'1 Lin the somegplane` with theroller 20 and spaced laterallyl therefrom. .The
cables then extendoneiover the roller 2O and the other-under it and are securedthereto so that whensaid roller is rotated theiplatforni 14 will be raised .or4 lowered; according to the direction in which the roller is turned.. The
roller ordrum20vis manipulated by a handle 27 as shownrin Figs. 2 and 3.`
The. spring 30constituting apart of lthis invention is composed of a .plurality of sections hingedly connected. The central section 31 is ii'xedlly connected `'with the side members 3. of the bedsteadl and is arranged directly over the plateaor slat 9and between which sectiony and ther slat `lare arranged' the coiled springsV 10. f

Any suitable means may be provided for hold- 4ing the handle or lever 44 in position to mainvvtarthe"section 32v raised, a catch 45 located on oneof the bed posts being here shown for "this purpose.
The .Imeetingends of the side bars of the sections 34'and 35 are' cut away or bevelled to permitl said sections to fold upwardly in relation to each other. (See fFig. 4.) ,A cross barv 46:, Vconnects the, side members of the sec# tion 34T near its outerendiand' operates as a bracef'forthesection.

WVhenfthe" foot section 33-is tobe swung down into the rposition shown in Figs;v 1 and 3: the hoolrs49a `are disengaged from the studs 47a which permits the frame 4'( 'to .11;
drop down by gravity out of theway of said section. This frame 4T when in lo'weredposition'is engaged withfand supported bythe frame `50 wliic'hcontrols the raising and low! eri'ngofthe-'ootsections 34 and 35.l i
The operating 'framefOv i's'also madefU.-
iixedly connected with said cross bar 52 intermediate the ends thereof so that when the outer end of the lever is swung downwardly its inner end will be swung upwardly carrying with it the U-shaped frame and the hingedly connected sections 34 and 35 of the foot section 33 of the spring. The upward movement of the frame 50 also carries with it the frame 47 the cross bar 49 of which overlies and rests on the lever 53 and hence is limited in its downward movement by said lever. The lever 53 is offset intermediate its ends where it is fulcrumed, being xedly secured at this offset portion to a shaft or rod 54 journalled in two upstanding bearings 55 and 56 carried by the lower portions of the foot boa-rd 2 as is shown clearly in Fig. 6. The outer end of the lever 53 is preferably provided with a hand grip 57 to facilitate the manipulation thereof.
It will thus be seen that when the frame 50 is manipulated by means of the lever 53 to swing said frame upwardly as shown in Fig. 4 it will carry with it the hingedly connected spring foot sections 34 and 35 and when they reach their eXtreme upward movement the lever will be past its dead center and will hold them in this position although obviously auxiliary means may be employed for holding the lever to prevent accidental dropping of the spring section. Normally when the frame 50 is swung upward the hinged section or member 35 of the foot portion of the spring will lie down in contact with the legs 51 of frame 50 and form a. V- shaped configuration in combination with the section 34.
Pivotally mounted on the legs 51 preferably about midway the length thereof is a rectangular frame 58 the lower portion of which is preferably weighted as shown at 59 to normally hold the cross bar 60 thereof in upright position. This cross bar 60 is designed to perform the function of a ratchet J for engaging teeth or cleats 61 carried by two strips 62 and 63 on the inner faces of the side bars of the section 35, and by means 'of which the section 35 may be held at any desired position in relation to section 34. As
-' shown in Fig. 4 the section 35 is supported in horizontal position so that a patient lying on the bed may have his leg below the knee extended outwardly while the thigh portion will be raised at an incline supported by the section 34.
It will be obvious that the weighting of the lower end of the frame 58 will cause the cross bar 60 thereof to swing automatically into engagement with the teeth or cleats on the section 35 when said section is raised and when the bar is disengaged from the. teeth and the section 35 swung downward into the position shown in Fig. 3 the frame 48 will lie flat against the frame 5() as shown in this figure.
A pivoted foot board 64 is connected by' means of links 65 to the side bars of the footy sections 35 of the spring and is provided with a hand grip 66 to facilitate its adjustment. This foot board 64 may be swung down flat against the outer face of the end member of the spring section 35 as shown in Fig. 4 or it may be raised and its lower end supported on the spring as shown in Fig. l. Vhen swung into the position shown in Fig. l and the foot section of the spring is dropped down this board 64 operates as a foot rest for the patient who will occupy the position as in areclining chair when the bed is as shown in Fig. l.
From the above description it will be seen that the hingedly connected sections of the bedspring 30 may be variously positioned to meet the convenience or requirements of the patient without necessitating removal of the f patient from the bed. It is of course understood that a mattress, not shown, is to be used in connection with this bed and that it will be preferably made sectional to conform to the sectional construction of the spring.
vWhile this bed is primarily intended as a hospital bed adjustable to vary the position of the patient according to his comfort, it may be also used as an ordinary bed when the parts are positioned as shown in 2.
Without further description it is thought that the features and advantages of the invention will be readily apparent to those skilled in the art, and it will, of course7 be understood that changes in the form, proportion and minor details of construction will be resorted to, without departing from the spirit of the invention or its scope as claimed.
A bed spring having a foot section composed of a plurality of hingedly connected members, one of the members having one y end pivotally connected to a fined part of the bed spring, a frame having one end pivotally connected with the other end of the lastmoved relative to each other for holding the last-mentioned member of the foot section in a predetermined position.
