Patented Oct. 14, 1952 UNITED STATES PATENT GFFICE TURNOVER BED Kenneth S. Keycs, J r., South Miami, Fla.

Application June 16, 1950, Serial No. 168,617

1 Claim. (Cl. -61) This invention relates to a turn-over bed, especially but not exclusively for use by a paralyzed and otherwise physically weak person whose position must be frequently changed to avoid bed sores and other maladies, the primary object of the invention being to provide a device of this kind by means of which such person can be rotated sidewise in either direction through a cycle of 180, that is, for example, from a position on the back to a position on one side, to a position on the stomach, without greatly disturbing or discomforting the person and without the tangling of arms or legs, without having to be handled by a nurse or attendant.

Another important object of the invention is to provide a device of the character indicated above involving two mattresses set at 90 to each other and sup-ported for rotation on a single horizontal longitudinal axis together with mechanism for rotating the mattresses together through an arc of 90, in such a way that a person lying on the device is rotated sidewise through an arc of 180, the mechanism being adaptable for manual or for electrical operation,

Other important objects and advantageous features of the invention will be apparent from the following description and the accompanying drawings, wherein, merely for purposes of illustration herein, a specific embodiment of the invention is set forth in detail.

In the drawings, wherein like numerals designate like parts throughout the several views:

Figure 1 is a side elevation, I

Figure 2 is a top plan view,

Figure 3 is a right hand end elevation of Figure 1,

Figure 4 is a similar view showing the device rotated 90 from the position shown in Figure 3, and

Figure 5 is an enlarged transverse vertical section taken on the line 55 of Figure 1.

Referringin detail to the drawings, the illustrated turn-over bed comprises an assembly 6 composed of a main normally horizontal mattress 1 having a bottom 8 from which depend feet 9 pivoted on brackets I0 secured to the bottom along one side of the mattress. In the normal position of the main mattress I the feet 9 depend to supportably engage the floor II. To the opposite side of the main mattress l is secured a secondary mattress I2 which projects above the main mattress I at an angle of 90.

Near the side of the main mattress I on which the secondary mattress I2 is secured, the ends of the main mattress I have bearings l3 spaced above the main mattress bottom, preferably at the center of gravity of the assembly, through which extends a horizontal shaft I4 which is fixed in any suitable manner to the bearings I3, whereby when theshaft I4 is turned in either direction the mattress assembly 6 will be similarly rotated. The shaft I4, and hence the adjacent side of the main mattress I, are supported by brackets I5 and I5 having bases I6 resting upon and secured in any suitable manner to the floor II and journal bearings I? on their upper ends in which the shaft M turns. One end of the shaft It has fixed thereon a gear Wheel IS.

The bracket I5 has below its journal bearing il a bearing IS in which is journaled a stub shaft 2!) having a crank handle 2! on its outer end. A pinion 22, in mesh with the gear wheel I8, is fixed on the stub shaft 2!). By rotating the crank handle 2| the mattress assembly can be turned in either direction through parts of the complete cycle of It will be evident that, if desired, the shaft I 4 can be rotated electrically, by means which are readily available, so that the person reclining on the bed could operate the assembly at will.

A double ended dog or pawl 23 is pivoted midway between its ends on the bracket I5 with opposite ends thereof selectively engageable with the pinion 22 to hold a selected position of rotation of the bed. The mattress I2 has feet 26 to engage the floor il in the horizontal position of the mattress I2.

What is claimed is:

In a turn-over bed, a mattress assembly comprising a main mattress normally occupying a horizontal position, a secondary mattress secured to a side edge of the main mattress and normally occupying a vertical position and extending upwardly from the main mattress, supporting means for supporting said mattress assembly in vertically spaced relation to and upon a floor to rotate from the normal position to an alternate position in which said secondary mattress is in a horizontal position and said main mattress is in a vertical position and extends above the secondary mattress, and. rotating means connected to said mattress assembly and arranged to act between said mattress assembly and the floor for rotating said assembly between the normal and the alternate positions thereof, said main and secondary mattress having feet extendin therefrom to supportably engage the floor at points spaced laterally outwardly from the axis of the supporting means in the normal and alternate positions of the mattress assembly.
