United States Patent 3,091,286 REMOTELY CONTROLLED SICK BED CURTAINS Mads P. Madsen, Brewster, Putnam County, N.Y. Filed Aug. 8, 1962, Ser. No. 215,649` 3 Claims. (Cl. 160-331) This invention relates, in general, to new and useful improvements which are used in connection with sick beds in private homes or in hospitals, and, more particularly, this invention relates to a remotely controlled sick bed curtain.
Hospital beds, particularly in hospitals, are generally surrounded or enclosed by curtains which may be drawn when privacy is wanted or examinations of the patient are to be performed by doctors. The curtains which are now used about sick beds in hospitals can only be drawn closed or opened by nurses or another person, not the patient, who can walk freely about the sick bed.
It is, therefore, an object of this invention to enable a patient who is confined to his sick bed to open or close a curtain adapted to surround his bed without the patient having to summon aid or even move in his bed.
A further object of this invention is to provide a sick bed curtain which may be activated to be opened or closed by the patients manipulation of a switch or but-V ton situated upon his bed or an adjacent night table within easy reach.
Another object of this invention is to provide an apparatus which enables a bedridden patient to control his en- Vironment to the extent of opening and closing his sick bed curtain so that the patients morale is given a lift in that one area, in which he was heretofore helpless, is now placed under his control.
Many other objects, advantages and features of invention reside in the particular construction, arrangement and combination of parts involved in the embodiment of this invention and its practice otherwise as will be understood from the following description and accompanying drawing wherein:

FIGURE 8 is a transverse vertical section through a fragment of the corner of the curtain track support frame.
Referring to the drawing in detail, FIGURES 1 and 2 show a conventional hospital type bed 10 having a metal 3,091,286 Patented May 28, 1963 rice headboard 11 and a footboard 12. By means of suitable clamps 13 two vertical support elements 14 are fixed to extend vertically upward from the footboard 12. Similar vertical support elements 15 are iixed to extend upward from the headboard 11. A generally rectangular curtain track support frame 20 is supported above and about the bed 10 by the brackets 21 and 22 which extend outward from the tops of the vertical support elements 14 and by the vertical support elements 15 which are directly attached to the curtain track support frame 20. Since the head of the bed 10 is generally against a wall; the rectangular curtain track support frame 20 extends only slightly behind the headboard 11 while it extends for a considerable distance past the footboard 12. This allows an examining physician or other visitor to move about the sick bed 10 with complete privacy within the curtain when it is closed.
Between the corners 24, 25, 26 and 27 of the support; frame 20, there extends the straight channel shaped. members 28. As shown in FIGURE 5, curtain track support brackets 29 are xed to the top wall of the channel members 28 and secure the top flange 31 of the curtain track 30.
Curtain support elements 32 each have two upwardly extending side portions 33 which carry the nylon rollers 34 that ride on the lower flange 35 of curtain track 30. A suitable hook 36 hangs from each curtain support element. The bed curtain 40 is supported by its upper edge at short regular intervals by a number of the curtain support elements 32.
The corners 25 and 26 have rounded cover plates 42 and 43 xed over them. The cover plates 44 and 45 are fixed over the corners 24 and 27 and they may be square for aesthetic reasons if the headboard 11 is placed adjacent to a wall.
The curtain track 30 is formed from one piece of extruded material which starts at corner 27 and is bent about corners 24 and 25 and corner 26 in a -smooth curve. Curved outer walls 50, as shown in FIGURE 6, are xed below the cover plates 42, 43, 44 and 45 between the ends of the channel members 28.
The leading edge 51 of the curtain 40, as shown in FIGURE 2, is secured to the track 30 by means of a leading edge curtain drive element. As shown in FIG- URES 3 and 4, this leading edge curtain drive element 52 consists of two curtain support elements 32 which are pivotally joined to a solid link 53. A single clamping member 54 containing a central aperture urged upward toward link 53 when the screws 55 are tightl-ned.
Referring again to FIGURE l, the dotted line 57 indicates the path of a length of drive cord 58 which extends completely about the curtain track support frame. The ends of the cord 58 pass under the link 53 and through the aperture in member 54. Thus the screws 5S may be tightened to clamp the ends of cord 58 to the leading edge curtain drive element 52. The element 52 negotiates the curved portion of track 30 with the elements 32 pivoting as do the trucks of a railway carriage.
Referring further to FIGURE 1, three or more pulleys 60 are rotatably mounted within the corners 24, 25 and 26. As shown in FIGURES 6 and 8, the pulleys 60 support the drive cord 58 at about the level of the curtain support elements 32 and the drive element 52 which slide along the curtain track 30.
Referring further to FIGURE l, corner 27 has two idler pulleys 61 and a centrally located drive pulley 62. Pulley 62 is mounted on a vertical shaft 63 which extends downward to a suitable gearhead electric motor 64 which is mounted below corner 45. As shown in FIGURE l, an electric wire 65 leads from motor 64 to a control box 66.
This invention operates in the following manner. The
curtain 40 is gathered beneath the channel` member 67 above the headboard 11 ofthe bed 10 in the open position. The curtain in this open position is shown in FIGURE 2. Thezleading edge 51' of the curtain `40is supportedby a.k leading edge rcurtain drive lelement 52 .which is xed to theV drive fcord 58 in the manner which has been described. The gearhead motor 64',4 which drives Ipulley62may `be activated to .rotate in -either direction .by thev control box 6 6. The box 66 may have two. buttons, one to open and one to. close the curtain 40, or it, mayv have a double throw reversing switch. Thuslthemanipulation ofcontrol box 66 activates motor 64 to ldrive the drive cord 58 in either direction. If pulley;v 62-.moves the `drive cord 58-'counter clockwise as shown in FIGURE .1, Athe drivecord will .draw the leading edge ofthe'curtain 40 about the curtain track support frame 2,0 alongthe track 30. In this manner, the bed 10-'may beA-completely'enclosed givingthe bedridden `paitientprivacy. By reversing the motor 64, the curtain 40 may be opened.
In order to have the curtain 40"negotiate the corners 24, and 26 without binding,l the curtain support elements 32 must. be.v disposed along the top of cuntain.40 so that, preferably, at least three curtain support members 32 are disposed,` on each curved portionof. track 30; This particular construction enables the curtain to be smoothly drawn completely aboutv the curtain support frame-20.
However, in drawing the curtain closed, the curtain support membersl 32Y negotiating the curved portions of track 'will tend to be ldrawn inward toward thevcenter of the curve. Any binding motionwhichmight then result may be mitigated if, as shown in FIGURE 8, the pulleysv60fare placedso thatthe drive cordY 58i is vin-close proximity tothe vinner sides of the .elements 32. In such a-case, should'the bottom ofthe curtainsupport elements 32 cock inward to any extent, the drive cord 58 will assist them about the curved portions of the track-30.
Whilel have disclosed my invention in the best form knownV to-me, it will nevertheless be understood that this is purely exemplaryand that modifications may be made without departing from the spirit of the invention except as itzmay be morelimitedzin the-appended claims wherein I claim:
