J. Application May 20, 1943, Serial No. 487,702 3 Claims. (Cl. 5-90) This invention relates to a hospital bed. An object of the invention is to provide a bed with reclining surfaces which can be disposed at many different angles to accommodate a patient in different positions and aid in moving the patient from one position to another. Another object is Il, i2, I3, and I4 (Fig. 4). These longitudinal frame members are arranged in pairs and the members of each pair are joined together at the foot of the bed by transverse pieces I5 and I6. Members i I and I2 are joined together by the transverse piece I5, and frame members I3 and to provide a bed of this character with a remov able portion near the center of the leg-support ~ I4 by transverse piece I6. These longitudinal members II and I2 and I3 and I4 form ñXed ing part of the bed. Still another object is to leg-supporting frames disposed along the outside provide a bedpan support for the bed to facilitate 10 of the bed near the lower portion thereof. Each the use and handling of this article with the pair is supported at the bottom end by a pair greatest comfort to the patient and minimum of legs. Legs I ‘i and I8 support the members labor to the nurse or attendant. Il and I2, and the legs I9 and 2i) support mem »Looking at the drawings, bers I3 and M. The top edges of members II Fig. 1 is a side elevation of the bed with certain 15 and I2 are joined together by a fiat member 2l, parts thereof shown in raised position; and members I3 and I4 by a similar member 22. Fig. 2 is a plan view, partly broken away, of Members 2| and 22 form the fixed leg-supporting one side ofthe bed; surfaces for the bottom of the bed.

In the following description and claims, the 35 terms “bottom,” “foot,” “top,” “head,” “right” These leg-sup porting members are hinged at the middlethere of, as shown at 30 and 3|, respectively, and at the upper ends thereof they are hinged. to the member 25 at 32 and 33. The ends of members 23 and 29 have a short turned-up portion shown at 34 in Fig. 9. These and “left” are used in relation to an occupant end portions are designed to engage underneath ' of the bed lying on his back. The “bottom” or transversely disposed tracks 35, 35’ and 35” “foot” of the bed is the end near the occupant’s which run across member 25 near the lower end feet, the “top” or “head” of the bed is the end 40 thereof to hold the leg supports in the general near his head, the “left” is the side near the position shown in Fig. 1. occupants’ left arm, and the “right” the side Supports 23 and 29 may also be positioned as near his right arm, shown in Fig. 9, that is, with _the lower part That portion of the bed framework adapted thereof supported in a horizontal plane. This to support the torso of the patient occupying the 45 is accomplished by means of suitable Supporting bed comprises side rails I and 2 and end rails ‘ upright members, one of which is shown at 36. 3 and 4 which together form a rectangle. This This member and its cooperation with member portion of the framework is supported on four 25 is shown in Figs. 11 and 12. Longitudinally legs disposed at the corners of the rectangular of member 25 are a pair of grooves 31 and 38 frame made up of the side and end members, 50 (Fig. 10) which are located under the center which legs are shown at 5, 3, "I, and 8, line of supports 28 and 29 near the lower or The leg supporting surfaces of the bed are foot end thereof. 'I'hese grooves are designed mounted on a framework made up of a trans to accommodate the supports 36. Each support verse member Iû attached to the cross member 36 has two hinges, one near the middle thereof, 4 and longitudinally disposed frame members 65 such as that shown at 39 (Fig. 11), and one near 2,407,892 3 one end thereof, such as that shown at liti. That portion of the supporting member which is shown in the groove 3l is marked 36’ and is somewhat wider than the groove 3l and designed to slide in slots 5| and 4|’ (Fig. 12). That por tion of the member Sëwhich is shown in a verti cal position in Fig. l1 and which is marked 3S” is somewhat narrower than the groove El? so as to permit the whole support to slide back and forth in the grooves ¿il and 4|’. The hinge 32 is so constructed that the member 3.5” can move in a counterclockwise direction from the position shown in Fig. 11, but cannot move any further in a clockwise direction therefrom. On the hinge S is a short square-cut catch marked il?. When this is raised into the position shown in Figs ll and l2, it will lock against the tracks 35, 35’ or 35" and prevent the support from mov ing to the right, as seen in Fig. 1‘1. Because of the hinge construction which permits the ele respectively, to ears 'i3 and le of side members 52 and 5|, respectively. f When the crank 61 is turned so as to rotate , lever ßf'â clockwise (Fig. 1) around shaft S3, arms 5l andY 59 are also rotated in the same direc tion, and the ends with pins 5| and 62 move up wardly, with the result that the main movable framework of the bed also moves upwardly. In this fashion the main framework may be pivoted around the pivot points 55 and 56. Because the cross piece 3 is lower than transverse members | 'and 2, the main movable framework may be lowered below a horizontal piane so that the head thereof may move below the top of the members i .and 2. This is desirable because sometimes it is necessary to maintain the pa " tient’s head lower thanhis feet. Within the main movable framework at the y torso-supporting end of the bed are a pair of auxiliary frames, each of which is hinged along seen in Fig. 11, the whole support may slide to the left, in which event the member [i2 can be the longitudinal center line of the bed. The auxiliary framework at the right side of the bed consists of transverse members ‘E6 and ‘i1 (Fig. dropped'down and slid along inside the groove 3l. This construction permits the support 33 to ber located in various positions longitudinally of the 'lil and l@ (Fig. 3). This auxiliary framework is pivoted at 8i! and Si (Fig. 2) to the main member 25 and at' the same time prevents move ment of the support 36 to the right, as seen in transverse members 53 and 5e of the main mov able framework.
