United tate .Patefi '0 2,829,383 ADJUSTABLE HEAD AND BACK REST FoR BEDS Charles 0. Creeger, San'Bernardino, Calif. Application November 9, 1955, Serial No 545,817

Claims. c1. 5 -327 The present invention relates to new and useful improvements in head rests for use with beds to support the head of a person in a raised or, lowered position when lying on the bed.

An important object of the invention is to provide a base frame on which a head rest frame is pivoted for raising and lowering movements by means of manually operated feed screws on which carrier blocks travel and I which are connected to the head rest frame.

Another object is to provide a disappearing head board to shield the feed screws from contact by the arms or hands of a person while'manipulating the head rest and to also prevent the hair of a personwhen occupying the bed from becoming entangled with the feed screws.

A further object is to provide a device of this character of simple and practical construction, which is efiicient and reliablein operation, relatively inexpensive to manufacture and otherwise well adapted for the purposes for which the same is intended.

jApair of bevel gears 17 and 18 are secured to the,

shaft 11 adjacent the ends thereof and 'the gears are re'spectivelyengaged with gears 19 and 20 which are se- .23 and 24 which have their leg portions 25 rockably mounted on shaft 11.

' Carrier blocks 29 and 30 are internally threaded to travel on the respective screws and the carrier blocks are pivoted on the smooth reduced inner end portions 31 of screws 32 whichare threaded intothe upperend of .an inverted U-shaped head rest frame26 for pivotal movement of the frame on the carrier blocks. The arms. 33 and 34' of frame 26are pivoted at their lower ends by pins 35 and 36 on brackets 37 and 38 at the front end portions of the side rails 6 and 7 respectively for vertical swinging movement of the frame 26 by,a raising 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 ac-' companying drawings forming a part hereof, wherein like numerals refer to like parts throughout, and in which:

Figure l is a side elevational view;

Figure 2 is a rear elevational view;

Figures 3 and 4 are enlarged fragmentary sectional views taken respectively on the lines 3-3 and 44 of Figure 1;

Figure 5 is a top plan view;

Figures 6, 7 and 8 are enlarged fragmentary sectional views taken respectively on the lines 66, 77 and 8-8 of Figure 2;

Figure 9 is an enlarged sectional view taken on a line 99 of Figure 7;

Figure 10 is an enlarged sectional view taken on a line 1010 of Figure 5; and

Figure 11 is an enlarged fragmentary vertical sectional view taken on a line 11-11 of Figure 1.

Referring now to the drawings in detail, wherein for the purpose of illustration I have disclosed a preferred embodiment of my invention, the numeral 5 designates a substantially U-shaped base frame which includes a pair of side rails 6 and 7 rigidly connected to each other at one end by a cross member 8 and by a cross brace 9.

Apertured bearing lugs 10 project upwardly from the cross member 8 in which a shaft 11 is journaled and to one end of which a crank handle 12 is detachably connected by means of a sleeve 13 fixed at one end to the shaft and in which the crank handle is secured by a cross pin 14 carried by a resilient clip 15. The cross pin passes transversely through the sleeve' and handle and the clip frictionally grips the sleeve to retain the cross pin in position. The other end of the shaft is enclosed in a cap 16 which is secured to an adjacent bearing lug 10.

of carrier blocks are connected to' each other forum-- form raising and lowering movement and also from turning movement on the feed screws by a cross bar 39.

A reticulated head rest spring 40 is secured to the cross bar 39 and arms 33 and 34 and against which a head rest'mattress 50 rests in an inclined position. The lower edge of themattress isforrned with a beveledor tapering construction as shown at 51 to merge with the usualbed mattress (not"sho'wn) without unduly increasing the thickness of the mattress.

The base frame 5 of the head rest is placed on the head portion of a bed mattress and the turning of the feed screws 21 and 22 by the shaft 11 and crank handle 12 willmove the carrier blocks 29 and 30 upwardly or downwardly to raise or lower arms 33 and 34 and which thus raises or lowers the head rest mattress to a desired inclined position A disappearing head board or shield is designated generally at 42 and comprises a plurality of telescoping sections 43, 44 and 45. Each section includes a panel member 46 having a channel 47 at each side edge and with the channels of section 44 slidable in the channels of section 43 and the channels of section 45 slidable in the channels of section 44. Stops 48, 49 and 50 are carried by the respective sections to limit upward sliding movement of each of the sections 44 and 45. Innermost ends of the U-shaped frame 26 by the screws 32 to support the head board in an upstanding position above the top of frame 26 and above the top of the mattress 50 to shield the upper ends of the feed screws and to pro tect the hair of a person when resting against the mattress, from becoming entangled with the feed screws.

The top 51 of telescoping section 45 -is engaged by the upper ends of the feed screws 21 and 22 when the frame 26 and mattress 50 are lowered to slide the sections 44 and 45 upwardly to shield the upwardly projecting ends of the feed screws, as shown by dotted lines in Figure l, and the upper sections 44 and 45 gravitate into their telescoping position when released by the feed screws.

As will be seen, the described head rest is also adapted for use as a back rest for a person seated in the bed.

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 claims.

Patented Apr. 8, 1958 i 1. A head rest for beds comprising a base frame, a a

' a'carri'er block pivoted to the upper portion of each arm,

feed screws threaded in the carrier blocks and imparting screw feed travel to the carrier blocks thereon relative to said shaft, and means swingably attaching the lower ends of the feed screws to the shaft in driving connection with the shaft and holding said feed screws immovable longitudinally; v

2; A head rest for beds comprising a base frame, a manually "operated shaft journaled on one end of the frame a'pair of arms pivoted to the other end of the frame for vertical swinging movement and against which ahead rest mattress is supported inan' inclined position, a carrier block pivoted to'the upper portion of each arm, feed screws threaded in the carrier blocks and imparting sa-w. feed travel to the carrier blocks thereon relative to said shaft, a pair of inverted U-shaped brackets swingably securedto the shaft 'andinth'e upper portion of which the lower ends of the feed screws are journaled and'said feedscrews held immovable longitudinally, and gears onthe shaft and feed screws connecting the feed screws andshaft in driving engagement with each other.

3. A head rest forbeds comprising a base frame, a manually operated shaft journaled on one end of the frame, an inverted U-shaped head rest frame pivoted at its lower ends to the other end of the base. frame for vertical swinging movement of the head rest frame and against which a headrest mattress is supported in an inclined position, a pairo-f carrier blocks pivoted to the upper portion of said head rest frame, feed screws threaded in the carrier blocks and imparting vscrew feed travel to the carrier blocks thereon relative to said shaft, a pair of bearing brackets swingably secured to the shaft and in which the lower ends of the feed screws are journaled and said feed screws held immovable longitudinally, gears on the shaft and feed screws connecting the same in driving engagement with each othef and a shield attached to and extending across the upper portion of said head rest frame and supported thereby in an upstanding position in front of the upper portion of the feed screws.
