INVALID BED.

Application filed November 23,1923. Serial No. 676,576.

This invent-ion relates to bedsteads, and is more particularly directed to an invalid bed which is capable of various adjustments.

The object of the invention is to provide a bed having a plurality of yieldable bed springs which may be readily adjusted to various positions for supporting patients in the most comfortable manner, the various positions being effected and the changes being made in a manner which is very favorable and desirable for the patient.

The invention will be best understood from a consideration of the following detailed description taken in connection with the accompanying drawing forming part of this specification, with the understanding', however, that the invention is not confined lto any strict conformity with the showing in the drawing, but may be changed and modified so long as such changes and modifications mark no material departure from lthe salient features of the invention as eX- pressed in the appended claims.

In the drawing:-

Fig. 1 is a plan view of the bedstead disclosing the mechanism connected with the bed for making various adjustments of the springs.

Fig. 2is a plan View of a plurality of springs which are placed upon the platform shown in plan view in Fig. 1.

Fig. 3 is a plan view of a horizontal spring frame.

Fig. 4 is a side view of my improved bedstead.

" of a swiveled connection for the supporting rods of the table.

Fig. 9 is a cross section taken along the line 9 9 of Fig. 6. Fig. 10 is a plan view of a foot rest which is detachably secured to theV foot frame.

Fig. 11 is a view in detail of an obstetrical instrument adapted to be secured to the bed.

Fig. 12 is a view in perspective of a device by which the patient may assist in raising himself.

Referring to the drawing, 1 designates the head frame, 2 the foot frame, and 3 the side rails of the bed. The head frame and foot frame are each provided with the hole low posts 4 and 5., respectively, the posts of each frame being connected by the usual decorative framework and the angle irons 6.

The posts 4 of the head frame and posts 5 of the foot frame are provided at their ends with collars 7, each collar having a screw-threaded perforation in which is adapted to be inserted a. set screw 8. Legs 9 are telcscopic'ally mounted in the posts ,4 and 5, and @positioned in place by means of the set screws 8 being forced up tight against said legs. The yusual casters 10 are mounted at the lower ends of the legs 9. The Vside rails 3 are formed of a plurality of sections 11 and l2, the respective sections yof each rail being pivotally connected by means of the hinge 13 secured to the under sides of the abutting ends of the sections 11 and 12.

Near the pivoted ends of the sections 11 of the side rails are secured hollow posts M telescopically receiving legs 15, which are slidably mounted in the posts 14 and held in adjusted position by means of set screws 16. The posts 14 and the legs 15 support the hinged end portions 11 of the side'railsA when the sections 12 and the foot fra-me o' are lowered angularly with respect to the side V'rails 3, and the foot frame 2 is positioned horizontally and supported luapon the -lorby casters 17 mounted in a collar 18 on the legs 9 of the foot frame.

It will be observed that by reason of the difference between the radius extending horizontally from the hinge 13 to the back of the foot frame and the radius extending diagonally from the hinge 18 to the caster at the 'end of the leg 9 of the foot frame, that the operator would experience diiiiculty in positioning the foot frame horizontally because the legs 9 would interfere with the movement by reason of their length, but sincethe legs are adjustable vertically within the posts of the foot frame, the set screws 8 may be loosened and the legs 9 shoved into the hollow posts 5 sufiiciently to permit the legs to clear the fioor and position the foot frame horizontally. r1`he casters 17, in this position of the foot frame, serve the same purpose as the casters 10 when the foot frame was in a vertical position.

llirmiy mounted upon the ends of the sections 11 of the rails 3 are a plurality of spaced bars forming an intermeoiate platform 19 uipon the opposite sides of which are pivotally mounted a head platform 2Q and a foot platform 21. rlhe head platform is formed of a plurality of equally spaced parallel bars 22 secured near their outer ends to a cross bar 23, the outer ends of the bars 2.4 restino; upon the angle iron (i of the head frame, while the inner ends of these bars are hingedly mounted at 24 to the intermediate platform 19.

The foot platform 21 comprises a longitudinally disposed bar 25 hingedly mounted at 26 upon the platform 19, spaced parallel cross bars 27 secured to the longitudinal bar 25, and an end cross bar 28 secured at right angles to the end of the longitudinal bar 25 and provided with perforated flanges 29 projecting upwardly from said cross bar. The cross bar 28 is secured in any approved manner to the sections 12 of the side rails 3. Mounted in bearings depending from the section 11 of the side rails 3, running,` transversely of the bed and located in the spaces between the bars forming the platform 19, are shafts 30 and 31. These shafts are operated by cranks 32 secured upon the outer ends of the shafts which project beyond casings 33 that house ratchets These ratchets are rigidly mounted on and near the ends of the shafts 30 and 31. Pawls 35 are pivotally mounted upon the section 11 of the the casings 33, ratchets 34, and pawls 35 are duplicated upon the opposite side of the bed.

its the shaft 30 is rotated in the direction indicated by the arrow in Fig. 4, cables 36 which are secured at one end to said shaft and at their other ends to the flanges 29 located on the platform 21, are wound upon the shaft and the foot of the bed is drawn upwardly from the horizontal position shown in Fig. 5 in full lines, to the vertical position shown in dotted lines.

W hen the shaft 31 is rotated in the direction indicated by the arrow in Fig. 4, the cables 37 which are secured at one of their ends to the shaft 31 and at their outer ends to the outer free end of the head platform 20, are wound upon the shaft 31 and the head platform is elevated at an angle to the horizontal plane passing through the middle platform 19. The foot lever 39 is depressed, forcing the arms 40 upwardly which engage bars 22 of the head platform and slightly tilting` the platform 2O from its horizontal position of rest; otherwise a great strain will be thrust upon the cables 37 since said cables are substantially in a horizontal position. The foot levers 39 are positioned inwardly and beneath the side rail 3 having` the stirrup 41 adapt-ed to receive the foot of the operator, and like the elevatinp; arm 40 are integrally mounted at one enden a rock shaft 42 mounted in bearings 43 which are secured at opposite points upon the side rails 3.

1f it beY desired at any time to lower the head platform29 or the foot platform 21, it will only be necessary to release the pawls 35 from engagement with the teeth of the ratehets 34 when the weight of the head and foot platforms will be sumcient to cause them to descend. It will be necessary to withdraw the legs 9 of the foot frame from the hollow posts o suflioiently to permit the casters 10 to rest on the floor. The set screws are again manipulated to secure the le. 9 in supporting position for the foot frame.

Upon the three platforms described above placed three springs 44, 45 and 46, which are hinged together by coil springs 47 and which may be considered collectively as a single bed spring. These springs are of the type commonly known as the vertical coil slning'. rllhe intermer iate spring 45 is fastened to the interm` diate platform 19 Vby means of hooks 48 which are secured to the middle platform 19. The head spring 47 and the foot spring' 46 are elevated simultaneously with the head platform 2O and the foot platform 21 respectively, while the intermediate spring' 45 must remain in sta` tionary position on the platform 19.

Mounted upon these three sets of springs is another spring having a pair of parallel Vjointed side bars comprising sections 49,

50 and 51, hingedly connected together by means of the hinges 52, the said hinges being` located above and in line with the hinged zii portion of the platforms,20 and 21. Latches 53, pivotally mounted near the ends of the different sections of the side bars of the spring 54, engage pins loer-.tedV on the abut-ting, ends of the adjacent sec-tions of in:

the side bars of the spring` and maintain the pivoted sections in rigid alinement. The transverse bars 56 are broken centrally and connected together by the hinges 57, 53, the outer ends of the hinges beingy secured to the adjacent ends of the end frames 5G and the inner portions 59 of the hingesabuttinp` and being secured upon the top plates 60 of boxes 61. The transverse bars are rigidly connected at their ends to the ends of the side bars by means' of plates 5,6?, whereby the bars 56 are offset at a higher level from the plane of the side bars.

These boxes are open aty theirV ends, and since the base of the bottom 62A is longer than the top, the sides of the boxes are Cut away as shown at 63 in Figs. 4 and 5. The bottoni` of each box is provided with a longitudinal slot in which is adapted to projecta pin 64, onev pin being secured centrally upon the cross bar 23 of the" head platform 21 and another upon the cross bar 28 of the foot platform 21. This construction of the boxes 61, and the pins 64 work# ing. in the longitudinal slots formed in the baises 62 of the boxes 61, provides a sepa- ,rable andV loose connection between the frame of the spring 54 and the headI and foot platforms, so that when the" head and foot platforms are tilted there will be had a certain amount of play between the lends of the spring 54, and theV head andv foot platforms.

The sections 49,A 50 and 51 of the side rail of the spring 54 are provided withV spaced perforations through which are inserted rings 65 which engage the outer edge portion of the spring 54, and secure these. portions o'f the spring to the side bars, so' that as the catches 53 are released from the pins 55, the spring 54 will be properly supported by the sections 49, 50 and 51 when the head platform is tilted upwardly' and the foot platform is tilted downwardly.

The end of the spring 54 nea-r the head of the bed is rigidlysecured to the transverse frame 56, while the end of the spring near the foot frame, which is spaced from thel transverse bar 56 is connected to the said bar by means-of springs 66.

As shown iny ig. 7, the spring 54 may not onlyV be broken transversely so that when the head platform is raised the head portion of the spring 54 may also'bev raised, and when the foot platform is lowered that the foot portion ofthe spring 54' may also be lowered, but it may be likewise' broken longitudinally, either portion 67 or 68j of the spring being adapted to be tilted.V The object of hingingvthe portions 67 and 68 of the springl 54 is to provide a means wherebythe patient may be readily and comfortably tilted or rolled in the bed tilting either one of the portions 67 or 68, as the case may be.

Upon the posts 4 of the head frames are adjustably secured, by means of set screws 70, sleeves 71. Collars 72 are swiveled upon the sleeve 70 by Ine'ansof` a pin 73', and are transversely perforated, thr'nighv which perforations are' inserted rods 74. A set screw "5.mounted in each collar 72 engages arod 74 to lock said rod' in position in the col'- lars 72. Upon the upper ends ofthe rod 74 are' secured' a table 76 and downwardly and inwardly projecting legs`7 7, the feet of which being adapted toA rest upon the side frames 11 when the table is lowered in a horizontal position before the patient. Before the table 76 may be lowered in horizontal position, it will be necessary to remove the lower ends of the rods 74 from engagement with the clips 78 which are secured on the posts 4 of the head frame and have outwardly-extending aws 7 9 adapted to engage the rods and hold them in vertical position. Secured to the underneath portion of the side rails 2Y of the' bed are spaced angle irons 80l extend-ing'- transversely of the 1bed and adapted to support a slidable tray 8l which is provided upon its outer ends with handles 82. The trayl 81 is designed for the pnrpose of supporting articles ordinarily usedin a sickroomv and beiiig slidable inv the angle irons 8O may be pulled out from either side of the bed.

The operation of my device is as follows:- o

The bed shown in Fig. 4 is in normal horizontal position. fIf it be desired to'turn the patient upon hisside', it will not be necessary to lift him since the spring 54'may be tilted longitudinally from either side' of the bedby raising either'V one ofthe portions 6T and68 of the spring 54.

lf it' be desired to place the patient in a reclining sitting position for the purpose of feedinghim, as shown in Fig. 5, thecrank 32 may be rotated in the direction indicated by the arrow to revolve the shaft 31 and thereby wind the cable 37 upon said lshaft to raise the head portion of the bed in an inclined position;l but before the head platforml 2O may be inclined in the'v position shown in F 5, it will be necessary for the nurse to release the catches 53 from the pins of the side' bars of the spring' 54, so that the frame of the spring may be broken at the hinged connections of the platforms 2O and 21. The pawls 35 will engage J(he ratchets 34, asthe crank` is rotated, so that the shaft 31 will beautomatically locked in in' position when the crank is turned and therefore the head platform will b'e automatically supported at any angle in which cable 36 and permit the foot frame to be lowered in a horizontalv position, the casters 17 engaging the floor of the room.

llO

If it be desired to elevate lthe foot frame to a vertical position, the crank attached to the shaft will be rotated in the direction indicated by the arrow in Fig. l, when the cable 36 will be wound upon the shaft 30 and exert a pull upon the foot frame, raising the same to a vertical position. The set screws S are released and the legs 9 allowed to fall or bev lowered from their telescopic engagement with the posts 5 until the casters l0 rest upon the floor of the room. The set screws 8 are then screwed tight to hold the legs in their adjusted positions for nipporting the bottom of the bed.

Tio replace the head i sections of the springs and platform in a horizontal position, the pawls are released from engagement with the ratchets while the crank 32 is held firmly and allowed to rotate in direction opposite to the direction indicated by the arrow in Fig. 4. The shaft 3l will slowly permit the cables, 37 to unwind as the head section of the bed is lowered by its own weight.

Iii.)

Rollers 36 are rotatably mounted on the bar 19 of the intermediate platform for engaging the cables 35 and are adapted to support the tables at those points in order to permit the foot frame to more freely be placed in position. v

The platform 84, shown in Figs. 5 and l0, is adapted to be detachably secured to the foot frame by means of spring clips which are adapted to embrace the post of said frame, and when in lowered position,

support the feet of the patient.

In Fig. ll is shown an obstetrical device for the purpose of assisting the patient in childbirth, and it is provided with a foot rest 86 and hand-grip 87 spaced from each other by a flexible means 88, such as a cord, rope or strap. The outer free ends 89 which extend beyond the hand-grip 87 are fastened to a hook 90 which is adapted to be secured to some portion of the bed.

ln Fig. 12, is shown a lifting device by which the patient may be elevated, or by which the patient may, by pulling upon certain elements of the device, raise himself or assist in the operation when he is being elevated, and comprises pairs of spaced pivoted legs 91 having their smaller portions 92 engaging and supporting a bar 93. The feet or lower ends of the pivoted bars 91 are adapted to be supported upon the side frames of the bed. The bar 93vprovides a cross beam upon which the hanger 94 is slidably mounted and which is provided with a rotatably mounted pulley 95 over which the rope 96 rides. The patient may be supported in any manner by one end of the rope 96, while the other portion may be drawn downwardly by the attendant and thus elevate the patient, or when the patient has recovered sufficient strength, he may grasp both ends of the rope 96 kand by pulling upon the same, sufficiently elevate himself for Awhatever purposes that may be desired.
