Application September 28, 1954, Serial No. 458,919

1 Claim. (Cl. ---72) The present invention relates to new and useful improvements in beds and more particularly to an adjustable head rest.

An important object of the invention is to provide a detachable head rest adapted for placing on a bed spring beneath a mattress and supported in position without the aid of fastening means of any character whereby the device may be interchangeably used on different beds.

Another object is to provide a base frame having a head rest ffame pivoted at one end thereto and mounting a manually operated pump on the base frame for a hydraulic cylinder connected to the head rest frame to enable a person occupying the bed to vertically adjust the head rest at will.

A further object is to provide an easily portable head rest adjusting device of this character of simple and practical construction, which is efiicient and reliable in operation, relatively inexpensive to manufacture and otherwise well adapted for the purpose for which the same is intended.

These, together with other objects and advantages which will become subsequently apparent reside in the details of construction and operation as more fully hereinafter described and claimed, reference being had to the accompanying drawings forming a part hereof, wherein like numerals refer to like parts throughout, and in which:

Figure 1 is a side elevational view showing the head rest in raised position;

Figure 2 is a side elevational view showing the head rest in lowered position;

Figure 3 is a perspective view showing the unitary head rest and adjusting means detached from the bed; and

Figure 4 is an enlarged sectional view of the pump taken on a line 4-4 of Figure 3.

Referring now to the drawings in detail, wherein for the purpose of illustration we have disclosed a preferred embodiment of our invention, the numeral 5 designates a U-shaped angle-iron base frame to the parallel sides 6 and 7 of which the side portions 8 and 9 of a U-shaped head rest frame 10 are pivoted for raising and lowering movement of the head rest.

Spaced apart parallel bars 11 are supported by the side portions of the head rest frame.

A V-shaped bracket 12 is secured at its upper ends to each of the side portions 6 and 7 of the base frame to extend downwardly therefrom and the lower ends of the brackets are braced by a transverse bar 13. A substantially vertical cylinder 14 is pivoted at its lower end to each end portion of bar 13 and a piston rod 15 is slidable inwardly and outwardly of the upper end of the cylinder and has its outer end pivoted to an adjacent side of the head rest frame.

A hose 16 is attached to the lower end of one of the cylinders and a hose 17 connects hose 16 to the lower end of the other of said cylinders. Hose 16 leads from a T-fitting 18 having its leg portion 19 attached to the top of a reservoir 20 which is secured to one of the side portions of base frame 5. A cut-ofl. valve 21 is mounted in the leg portion 19 of the fitting 18.

A second T-fitting 22 also has its leg portion 23 entering the top of the reservoir into liquid 24 therein and the lower end of leg portion 23 is provided with a ball check valve 25 having a coil spring 26 behind the valve to close the lower end of leg portion 23 of fitting 22. One end of fitting 22 is connected to the rear end of fitting 18 and is closed by a spring-loaded ball check valve 27 and the rear end of fitting 22 is connected to a pump cylinder 28 having a piston 29 working therein and operated by a lever 30 pivoted to the adjacent end portion of the reservoir.

Folding braces 31 connect the base frame to the head rest frame adjacent the free end of the latter and a spring 32 connects the lower arm 33 of each brace to the base frame to break the braces in order to lower the head rest.

The base frame 5 is placed on one end of a bed spring 34 under a mattress (not shown) and valve 21 is closed whereupon the operation of lever 30 will pump liquid from the reservoir 20 to the cylinders 14 to force the piston rods 15 upwardly to raise the head rest frame 10. The frame 10 may be lowered by opening valve 21 so that liquid from cylinders 14 will be drained back into the reservoir through the leg 19 of fitting 18.

From the foregoing, the construction and operation of the device will be readily understood and further explanation is believed to be unnecessary. However, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction shown and described, and accordingly all suitable modifications and equivalents may be resorted to, falling within the scope of the appended claim.

What is claimed as new is as follows:

An adjustable head rest comprising a U-shaped base frame of angle iron construction including a downwardly projecting flange adapted for resting on the head portion of a bed spring and with the downwardly projecting flange of the base frame positioned at the outside of the end and side portions of the spring to maintain the base frame in position, a U-shaped head rest frame pivoted at its leg portions to the leg portions of the base frame for vertical swinging movement of the former, a V-shaped bracket at each side of the base frame and extending downwardly therefrom, a cylinder pivoted at one end in an upstanding position to the lower end of each bracket, a piston rod at the upper end of each cylinder and pivoted to the head rest frame, manually actuated fluid pressure means carried by the base frame and connected to the cylinder for raising and lowering the head rest frame, a foldable brace connected to the head rest frame and base frame, and spring means connecting the brace to the base frame for folding the brace to lower the head rest frame.
