sitting position thereof for obtaining a more comfortable sitting position for the patient.
Another object of the invention is to provide l an invalid bed in accordance with the foregoing object wherein the component parts of the bed can be adjusted relative to one another after it has been placed in a sitting position to change the angularity between the component parts te give the most comfortable position to a patient. Y
Further objects and advantages will become apparent from the drawings and the following description.

Figure 13 is an elevational view of a crossbar that can be inserted in the arm rest holders for extending transversely across the bedr:
Figure 14 is an elevational view of a side rail that can be supported in a pair of arm rest holders on the frame of the bed.
In this invention, the bed consists of a pedesta or frame II) consisting of a pair of longitudinally extending tubular members I I that are joined by a pair of transversely extending tubular members I2 and I3. This frame also is provided with the legs I4 having rollers I5 on the end thereof. The tubular frame members II, at the juncture between the legs I4 and the frame member II, are provided with a pair of side plates I6 and I'I at the front and rear corners of theframe I0 that are joined by a square tubular member I8.
The Amain bed frame 20 consists of three com ponent parts, afoot section 2|, a middle section :22, and a head section 23 that are pivotallyl connected together. The parts 2I and 22 are pivotally connected by means of a rod 24 extending vtransversely between the frame members, and
the frame members 22 and 23 are pivotally` connected together lby pivot pins 25 extending through the respective frame lmembers. The
'f brackets 2'I which are slidably connected to lthe One of the brackets 21 is provided along each side of the bed-frame, and since both brackets are identical, except for being arranged on the left and right-hand sides of the pedestal I respectively, only one of the brackets will be described, which is that located on the righthand side of the pedestal lll.
The bracket 21 carries a channel-shaped member 2B secured thereto in any suitable manner which slides upon a guide member 29 secured to the side plate il attached to the pedestal l0. The guide member 29 is disposed at a downwardly inclined angle toward the head end of the bed so that when the bed is moved from the reclining position, as illustrated in Figure 1, to the sitting position as illustrated in Figure 2, the bracket 21 will move downwardly and toward the head end of the bed simultaneously.
When the bed is in the sitting position, as illustrated in Figure 2, it will be noted that the portion 22 of the bed forms the seat portion and is inclined downwardly toward the head end of the bed to make for a more restful position when a patient is sitting in the bed. Also, it will be noted that the pvot between the sections 22 and 23 of the bed 26 is disposed to one side of the frame pivot so that the weight of a person on the bed will be thrown in a direction downwardly, tending to aid the folding of the bed at this pivot 25, and thereby relieve the energy required of an operator to lift a person to a sitting position. The movement downwardly or the pivot 25 causes the bracket 21 and the section 2| of the bed to be drawn rearwardly to place the joint between the sections 2| and 22 at the proper knee position for a patient and to lower the same sufriciently to maintain an inclined angle of the seat portion 22 for obtaining a restful sitting position of the elements of the bed.
The head end of the bed 23, namely, the section 23 thereof, is provided with a frame structure 30 around the edge thereof which prevents a pillow from sliding off the end of the bed, and has an upstanding portion 3| which may form a backrest in case a patient desires to sit up in bed while it is retained in a reclining position.
The section 23 of the bed 2i) is adjusted to reclining position, shown in Figure 1, and held therein, by means of a bracket 32 pivotally mounted upon a pedestal lil, and particularly upon the inner side plate extending between the members |I and I8 of the pedestal.
The bracket 32 has an arm 33 pivotally carried thereon by means of a pin 34, and the arm 33 is pivotally connected to the section 23 of the bed by means of the pin 35. The bracket 32 also has a series of holes 35a arranged in an arc thereon, adapted to receive a locking pin that is operated by the handle 35. The p-in operated by the handle 36 is located in one of the holes 35a. to hold the jack-knife mechanism consisting of the members 32 and 33 in rigid position and thereby hold the section 23 in position relative to the remaining sections 22 and 2|.
The locking pin that is operated by the handle 36 is more clearly illustrated in Figures l1 and 12. As shown herein, the handle 36 is carried upon a rod 31 that extends transversely across the bed to a similar operating mechanism on the opposite side thereof. The rod 31 carries a cam member 38 secured thereto for rotation therewith upon actuation of the handle 35. A torsion spring 39 is provided around the rod 31 and has one end thereof fastened to the cam 33 and the opposite end to an enclosure 40 that encloses the cam 38.
The cam 38 is adapted to engage a shoulder or collar 4| provided on the locking pin 42 that enters one of the holes 35 in the member 32 of the jack-knife mechanism which consists of the members 32 and 33. Normally, the compression spring 43 holds the locking-pin 42 in position in the holes selected.
Rotation of the cam 38 moves the high point thereof into engagement with the shoulder 4| to remove the pin 42 from the hole 35 and thereby allow movement of the section 23 of the bed for raising or lowering of the same, or for adjusting the position of the bed when it is placed in sitting position as illustrated in Fig. 2. The
rod 31 simultaneously actuates the mechanism on both sides of the bed through means of similar cam arrangements as just described. The released position of the locking mechanism is shown in Fig. 12. If for some reason the handle 36 should be released at any time during the raising or lowering of the section 23 of the bed, the torsion spring 39 will automatically place the cam in the position indicated in Fig. l1 to cause the pin 42 to drop into one of the holes 35 and thereby prevent the section 23 of the bed from falling completely.
The foot section 2| of the bed 20 is adjustably held in position by a similar jack-knife mechanism, as just described, consisting of the members 32d and 33a and a corresponding locking mechanism 52a. The member 33a is pivoted to the section 2| by means of a pin 43a and to the member 32 by the pin 44, the member 32a being pivoted to the V-shaped bracket 21 by means of a pin 45. One such mechanism is placed on each side of the section 2| of the bed and operated simultaneously by a handle 46 on either side of the bed.
An adjustable foot-rest is provided for the bed and consists of a foot-plate 50 pivotally carried upon a pair of rods 5| extending along opposite sides of the bed 2D, the rods 5| being pivotally mounted to the plates 52 positioned adjacent opposite sides of the frame section 2| and the foot frame portion 53. The foot-plate is provided with an arcuately shaped member 54 adapted to be placed upon the foot frame 53 when the foot-rest is in its extreme position at the end of the bed section 2|.
The foot-plate 5|) may be adjusted to various positions, such as the position illustrated in dotted lines in Figure 2, by releasing a latching mechanism 55 of any suitable type to allow movement cf the arm or rod 5| and causing the latching mechanism to engage any one of the holes 55 in the plates 52 for holding the foot-plate 50 in any selected position.
A pair of arm rests 5!) is provided on opposite sides ofthe bed, these arm rests each being provided with a post 2| adapted to lit upon a stud carried upon the arm rest holder 52 that is mounted upon the square rod I8 of the pedestal lil. The post 6i is provided with a series of slots 9G, see Fig. l, around the lower edge thereof adapted to t upon a pin 9| extending through the stud in the holder 52 to allow for positioning the arm-rest 5&1 in any angular position relative to the bed 20. The arm rest holder 52 is adapted to be adjusted longitudinally along the rod I3 to position the arm rest 55 at any position along the bed such as that illustrated in Fig. l or that illustrated in Fig. 2. The arm rests 55 can be used for holding serving trays of various types either for convenience of the patient attendants or for the convenience of the patient.
e TheA arm rest holder 62 consists of a frame 65fslidable upon the tube I8. The frame 55 carries a reciprocating member 66 having a pin 61 therein adapted to enter holes in the bottom edge of the tube |8,- thepinl being held in position' bythe compression springs 68, thereby holding the arm rest holder "62' in any selected position along the length of the tube i3.
In Fig. 13 there is illustrated va U-shaped bar 70 that is adapted to extend transversely across thebed Zilv'between the holder members 62 positioned uponeach of the rods l'extending longitrudinallyv of the pedestal I Q.' This bar lis for the purpose of providing a grasping-bar for patients to aid in raising themselves in bed.
If desired, a side-rail can be provided for the bed 2l] in the manner illustrated vin Fig. 14 wherein the bar 1| is adapted to be supported by a pair of carrier members 62a mounted upon the bar I8, the rail 1| extending longitudinally along the side of the bed 2i). In this case a serving tray or arm-rest 12 may be carried by the bar 1|.
When the three sections 2|, 22 and 23 of the bed 2U are moved from the flat position illustrated in Fig. l to the angular position illustrated in Fig. 2, the springs 30 of the bed 20 tend to straighten out across thel pivot joints indicated at 24 and 25, in the manner illustrated in Fig. 8 shown by the dotted line 86a. If this condition was allowed to exist an uncomfortable condition is developed at the juncture between the sections 2|, 22 and 23. To avoid this condition, particularly at the juncture 25 between the sections 22 and 2?, an angle bar B5 is secured between the side frames of the section 23. A series of tension springs 86 extend between the angle bar 85 and a transversely extending wire 81 of the spring 80, thus continuously pulling the wire 81 downwardly so that the spring 80 is forced to follow substantially the contour indicated in full` lines in Fig. 8. The arrangement thus provides a relatively square corner at the juncture between the sections 22 and 23.
The rod 24 that extends transversely across the bed 2i! and forms the pivot for the sections 2| and 22 passes beneath the spring 8D as illustrated in Fig. 3. Thus, when the sections 2| and 22 are positioned angularly to one another, as illustrated in Fig. 2, the spring 80 passing over the bar 24 will be prevented from forming a large arc at this point by the arm 24. Thus, it is possible in the bed of this invention to obtain a substantially chair-like effect of the bed when it positioned as illustrated in Fig. 2.
A pair of springs 90a extends between the pivot 25 between the sections 22 and 23 and the tube of the pedestal I0 to aid in rotating the section 23 about the pivot formed by the brackets 26 when the bed is moved from the flat position illustrated in Fig. l to the angular position illustrated in Fig. 2.
While the apparatus disclosed and described herein constitutes a preferred form of the invention, yet it is to be understood that the apparatus is capable of mechanical alteration without departing from the spirit of the invention, and that all such modifications as fall within the scope of the appended claims are intended to be included herein.
