1 Claim. (Cl. -66) This invention relates generally to devices for use in hospitals and particularly to a bed for hospitals.

The main object of this invention is to provide a bed whereon a person may recline in a horizontal position or with the head or foot end of the bed elevated.

The second object is to provide a bed which will be extremely portable.

The third object is to so construct the bed that it may be adapted to a wide range of operating conditions.

The fourth object is to provide a bed having more and convenient storage space under it and to make the bed section separately removable.

These and other objects are accomplished in the manner set forth in the following specifications as illustrated in the accompanying drawings, in which:

Fig. 1 is a side elevation of my bed upon a supporting framework.

Fig. 2 is a perspective view of the supporting frame with all attachments removed.

Fig. 3 is a fragmentary view of a typical form of joint.

Fig. 4 is a perspective view showing the bed portion adapted for use with a bed pan.

Fig. 5 is a transverse section taken along the line 5-5 in Fig. 4.

Fig. 6 is a perspective view of a cabinet adapted to occupy space between the upper and lower longitudinal bars.

Fig. 7 is a fragmentary perspective view of a joint when the frame is constructed of channel bars.

Like numbers of reference refer to the same or similar parts throughout the several views.

Referring in detail to the drawings there is shown in Fig. 2 the supporting structure of the bed. It comprises a plurality of upright legs 10, 11, 12 and 13 under which are the caster wheels 14 which ride upon the floor 15.

Longitudinal braces 16 unite the legs and 11, braces 17 unite the legs 12 and 13 and braces 18 unite the legs 10 to 10, 11 to 11, 12 to 12, and 13 to 13 transversely while cross braces 19 provide lateral rigidity to the support. Each leg 10 to 13 is provided at its upper end with a transverse hole 19-A. Legs 11 and-12 are united by the ties 20.

Between the legs 10 and 11 and between the legs 12 and 13 are disposed the cabinets shown in Fig. 6. These are comprised of side walls 21, top 22, bottom 23 and front 24, which front is flanged along its top and bottom edges 25 and 26 to provide fastening means to the braces 16 and 17 to which they are attached by screws through the holes 27. Doors 28 are provided in front of the shelves 29 and water tank 29-A. Obviously the cabinets may be fitted up as desired.

The shape of the parts 10 to 19 may be angular, channel, or'round, or any other shape desired and the material may be any available and suitable for the purpose.

The cot or bed portion of my invention is more fully set forth in my United States Patent 2,468,253, over which the present device is an improvement.

The bed is formed of side rails 30 and 31, which are hinged by means of the pins 32. Each rail 30 and 31 has feet 33 and 34 depending therefrom, which are attached by pins 35 to perforated links 36, which in turn are secured to the legs 10-13 at the opening 19-A.

A bed spring 37 may extend along the full length of the bed by resting on the rails 30 and 31 or the spring 37 may be pulled out as shown in Fig. 4 to make room for a sanitary section 39 of rubber, beneath which may be disposed a suitable container 40.

Rails 30 and 31 are longitudinally slotted at 41 to slidably receive the various units mentioned. Springs 37 are preferably made in individually removable sections such as 42 and 43, each section having longitudinal frame members 44 comprising angle irons with horizontal flanges engageable in slots 41. Container 40 is adapted to rest in a flanged pan or tray 45 supported by an angle iron or other suitable frame 46 having flanged edges engaged in the slots 41 after removal of a bed spring section. Section 39 has a metal frame 47 adapted to rest on shoulders 48 of the rails 30, as shown.

When the frame is constructed of channel bars the joint shown in Fig. 3 may be formed as shown in Fig. 7, the members 12a and 20a corresponding to the members 12 and 20, respectively, in Figs. 1, 2 and 3.

I claim:

A wheeled frame comprised of two longitudinal rows each of four vertical rigid supports projecting upwardly from said frame, a pair of tubular side rails disposed over each row of supports, each of said side rails having a guide formed on the side facing the opposite rail, the rails on each side being hinged to each other at adjacent ends between the innermost supports, each side rail having a pair of depending feet registering with two of said supports, a perforated link hinged to each foot and adjustably attached to a support whereby said side rails may be inclined in either direction, and slidable units mounted in the guides of said side rails.
