ZACK S. LOG-AN AND WILLIAM P. PIKE, OI LOUISVILLE, KENTUCKY, ASSIGNORS TO THE LOGAN 00., OF LOUISVILLE, KENTUCKY, A CORPORATION OF KENTUCKY BED Application filed August 25, 1930; Serial No. 477,593.

This invention relates tonew and useful improvements in beds, and whileit is of general application, it is particularly designed for use in conjunction with beds having head rests whereby the occupant of the bed is prevented from slipping away from or upon the head rest when using the'same.

With the above and other objects in view as will be apparent, this invention consists in the construction, combination and arrangement of parts, all as hereinafter more fully described, claimed and illustrated in the accompanying drawings wherein:

Fig. 1 is a side elevation of a bed embodying the present invention;

Fig. 2 is a plan view of the head end thereof illustrating the operating mechanism for both the head rest and a non-slip or seat device forming the subject matter of the present invention; and

Fig. 3 is a fragmentary side elevation of the head end of a bed illustrating a modified form of the present invention coacting therewith.

The present invention is primarily designed for use in conjunction with hospital beds wherein one end of the spring frame or equivalent structure may be raised, together with the mattress thereon, to act as a head rest for the bed occupant. When such head rest is in use the occupants body reclines against the rest and there is a decided tendency for the body of the occupant to slide toward the foot of the bed. The present invention is designed primarily to eliminate such movement or tendency by placing a body rest or seat in advance of the base of the head rest so that as the patients body reclines against the head rest he will also occupy a substantially seated posture upon the nonslip or seat device forming the subject matter of the present invention.

The present invention also contemplates the automatic and simultaneous elevation or operation of the seator non-slip device with the head rest so that as the head rest is raised the non-slip device or seat is likewise raised, and reversely, as the head rest is lowered, the seat or anti-slip device will also be lowered.

Reference being had more particularly to the drawings 10 designates a bed frame having a foot end 11 and a head end 12. A spring frame'13 is mounted upon the bed frame 10 and is provided with a head rest section 14: which is hinged to the remainder of the frame as at 15. In order to operate the head rest 14 to raise and lower the same, a'shaft '16 is disposed below the bed frame 10 and extends from the foot end 11 to the head end 12; The

head end 12 is provided with a bearing 17, in which one end of the shaft 16 operates loosely and may reciprocate. The foot end 11 of the bedadj oining the end of theframe 10 is provided with a bearing 18 into which the opposite end of the shaft 16 extends. This shaft 16 does not rotate but is movable longitudinally of the bed frame 10 in the bearings 17 and 18. The longitudinal movement of the shaft is accomplished by the crank 20, or equivalent mechanism, at one end of the bed through a means which,as it forms no part of the present invention, is neither shown nor described herein. As the crank or equivalent mechanism 20 is rotated or operated in'one direction or the other, the shaft 16' moves 10ngitudinally with respect to the bed frame 10. i A link mechanism L, forming no partof the present invention, is interposed between the head rest 14: and the shaft 16 so that as the shaft is reciprocated, as above described, the head rest will be raised or. lowered; thus by moving the shaft in one direction the head rest 14 is elevated to a position at an angle to the bed frame 10 as shown in full lines in'Fig. 1 and when the shaft 16 is moved in the opposite direction the head rest is lowered to occupy a position parallel to the-bed frame 10,

as shown in dotted lines in Fig. 1.

The section 21 ofthe spring frame to which the head rest 14 is pivoted at 15 is fixed to the bed frame 10 and is immovable with respect thereto. All other portions of the spring frame 13 are movable with respect to the bed frame 10 as will be hereinafter described.

Pivoted at the opposite side of the section if spring frame, which also has pivoted thereto, 100

as at 26, a second and similar seatsection 23 that, in turn,

is pivoted as at 24: to the main portion 13 of the spring frame. When the seat sections 22 and 23 occupy the position shown in full lines of Fi 1, the head rest 14: is elevated and the occupants back may recline against the said rest while partially seated upon the first section 21 of the spring frame with the thighs resting at least in part upon the said section 22. Thus the occupantof. the bed is supported against the head rest 14: and is prevented from slipping downwardly along the head rest and the spring frame.

Then the head rest occupies the dotted line position shown in Fig. 1, the said sections 22 and 23 are designed to occupy similar positions so that all of the sections ofthe spring frame will rest coplanar one with the other and present a smooth flat sleeping surface.

The mattress of the bed is, of course, placed upon the spring frame and moves with and as the aforesaid elements of the spring frame move.

arms 23 are fixed to the shaft 27 and at their outer terminals are pivotally connected to a second transverse shaft 29. 'The ends of this second transverse shaft 29 are provided with upwardly extending arms 30, which are secured to the pivots 26 between the seat sections 22 and 23. A link 31 is pivoted to the shaft 16 at a point below the sections 22 and 23 of the spring frame and this link is in turn pivoted to the shaft 29 as at 32. Thus as the shaft 16 is moved longitudinally the arms 28, having fixed pivots on the shaft 27 are oscillated by the link 31, which causes the shaft 29 to swing with the link 31 raising and lowering the arms 30. Thus the movement of the shaft 16 in one direction moves the pivot of the arm 31 toward the bearing 17 swinging the outer ends of the arms 28 upwardly about the shaft 27, thereby elevating the shaft 29 and the arms 30 and raising the pivots 26'between the sections 22 and 23. In

:this manner the seat sections 22-23 are positioned at angles one to the other and to seeions of the spring frame connected by the pivot 24. This movement of the elements causes the body of the spring frame to slide upon the bed frame 10 toward the head end 12. The reverse movement of the shaft 16 causes the pivot of the link 31 to move toward the foot end 11 of the bed, which in turn causes said link 31 and arms 28 to swing above the shaft 16. A.

waves downwardly toward the shaft 16 thereby lowering the shaft 29 and the said sections of the head rest 14 and from the same oper- V ating mechanism the said sections 22 and 23 are raised and lowered. r

In Fig. 3 is disclosed a modified form 0 the present invention wherein the body 13 o the spring frame remains resting upon th bed frame 16 irrespective of the position or the head rest 14 or of'the seat or anti-slip device. shaft 16, by its longitudinal movement through the link mechanism L raises and lowers the head restli of the spring frame as in the structure shown in Fig. 1. The anti-slipping or seat device, forming the subject mattertof the present invention constitutes a pair of plates 33 pivoted to the pivot 15 connecting the head rest 14 to the spring frame 13. These plates disposed upon each side of the bed frame 10 and are connected by a fiat metal bar or strap 34 whereby they operate in unison. Disposed below the strap or bar 3e'is a U-bar 35, the arms of which extend between the bed frame 10 and the mattress and spring while the body of the bar 35 res-ts below the lower plane of the mattress and spring. with a central roller 36 which is disposed sloping track 37 is attached to the shaft 16 so that as the shaft reciprocates as above described, the track will move under the roller 36. Thus, as the shaft 16 is moved longitudinally in one direction to elevate the head rest 1 1, the roller 36 is caused to travel upwardly on the track 3! thereby elevating the U-bar 35 and plates 33' and by that means raising the mattress resting there:

on. IV hen the shaft 16 is moved longitudinally in the opposite direction the roller 36 travels downwardly upon the track 37 permitting the U-bar 35, plates 33 and strap or bar 3 1, together with the mattress thereon to move downwardly toward the bed frame 10 untilthe strap 34 rests directly upon the springs of the frame 13. i

Again it is apparent that simultaneously with the raising and lowering of the said rest 14-, the seat structure is raised and lowered to provide a support for the occupant of the bed in advance of the head rest 14.

From the foregoing it is obvious that in both forms of the present invention the head rest 14 is raised and lowered by the longitudinal movement f the shaft 16 and that at the same time the non-slipping device or seat structure is correspondingly raised and lowered from the shaft 16. In this manner This U-bar is provided when the seat structure or non-slipping device and the head rest are lowered a plane smooth sleeping surface is provided while the raising of the head rest automatically positions the non-slipping device or seat structure in advance thereof so that the occupant of the bed, in reclining against the head rest is so supported that therewill be no movement toward the foot end of the bed.
