Application February 23, 1956, Serial.No.- 567,2 0.1
Claims. (Cl. 160-62) Generally, the present invention relates to protective devices-of the type that may be installe'd on the Window and door frames of buildings, dwellings, and the like.
Moreparticularly, the present invention relates to a novel construction including a roll-up or flexiblemetallic curtain that may selectively be employed in-"either an awning or in a shutter capacity.
Curtains of this type are usually'constructed of a pinrality of narrow panel members or slats that have'rockable, or what may be termed flexible interlocking connections along their adjacent edges. Theuppermost 'slat of the curtain is usually permanently secured above a window or door opening. The lowermost slat is secured to a roller or cylinder that is rotatably supported by a pair of arms hingedly mounted on a lower portion of the frame surrounding the opening. In consequence of this arrangement, when the free ends of the arms move away from the frame, the curtain will unfold outwardly and downwardly as is well understood.
The present invention is designed-"to incorporate a roll-up awning of the windrup type, preferably that disclosed in the copending, application of Harry Nelson, filed January 27, 1956, SerialNumber '561,900;assigned to the assignee of the instant application. The Nelson disclosure includes a pair of winding*'devices .thatare disposed in the end portions of the cylinder'to'which the lowermost slat of the articulated curtain" ispattached. These winding devices include coil *springarrangements adapted to normally maintain the curtain in'rolled-up status.
The primary object of-this-invention is'to provide a novel arrangement whereby an'auto'matic roll-up awning such-'asthat referred to may be1readily' utilized also to serve as a shutterwhen desired. T o thisend, the'uppermost panel of the curtain is-'releasablynetained, rather than permanently secured, above a building opening.
Stated more explicitly, it'is the principal" object .of
constructionthat may be fabricated in" any desired length withoutdepartingfromllre structural concepts to be set the window or other openingin'any manner whatsoever. 7
That is to say, the rolled-up curtain wouldbe supported by means .ofthe, arms .so as tojlie adjacent the window framegor building wall above the opening.
Other novel'features and adyantages of, thewinvention not specifically noted hereinbefore will, be apparent or mentioned in the detailed descriptiomtofollow with reference to two sheets .of drawingswherein:

Patented Sept. 29, 1959 groove 30 is coextensive with the cylinder 32, and said lowermost slat is retained in position against lateral movements thereof by caps 34 that are pressfitted onto the opposite ends of said cylinders 4 At this point it is to be noted that the wind up mechanism 36 appearing in Figures; 12 through 14 has been illustrated solely for the'purpose of clarifying theope'ration of the present invention. That is to say, whereas this invention incorporates said mechanism, no claim thereto per se is made herein, inasmuch as it constitutes subject matter disclosed in the copending application aforesaid of Harry Nelson.
As the Nelson disclosure teaches, identical wind-up mechanisms 36 are provided in both ends of the cylinder 32. Briefly, each of the mechanisms 36 includes a torsion rod 38, a coil spring 40, and a peripherally flanged disc 42. The rod '38 extends into the cylinder through a bearing 44 in the end cap, whereby the two rods rotatably support the cylinder at each end thereof. Outside the cylinder, each torsion rod is bent right-angularly to form an extension 46, as shown particularly in Figures 4 through 6. The innermost end of said rod is slotted and deformed as at 48 whereby to anchor the inner convolution of the spring 40, the outer convolution being anchored in the disc 42 as shown. Said disc is slidable longitudinally of the cylinder, but restricted against rotary motion by the provision of an arcuate indent 50 that partially embraces the cylinder recess 30, as shown in Figure 12.
In accordance with the concepts of the present invention, the top marginal edge of the uppermost slat 24 is formed to provide a coextensive semicircular segment 52, as best seen in Figures 8 through 10. Numeral 54 designates a round metallic bar that is welded or otherwise positively secured into the segment 52. The bar 54 is of greater length than the slats 24, so that the end portions 56 thereof project therebeyond, as particularly demonstrated in Figure 15.
Rigidly attached in any suitable manner centrally of the bar 54 is a tape or drawstring 58 that preferably has a ring 60 secured to its depending extremity. Further, as disclosed in said copending application, a draw cord 62 is anchored at one end to the cylinder 32, and when the curtain is in awning status, the free' end of said cord is tied to a cleat or hook 63 projecting from the window sill S, as shown in Figure 5. When the curtain is in shutter status, the ring 60 on the extremity of the drawstring 58 is looped over said hook, as best seen in Figures 3 and 6. v
Each of the torsion rod extensions 46 issecuredto the free end portion 66 of one of a pair of tubular arms 64. The opposite end portion 68 of each of said arms has a pivotal connection 70 with one of a pair of brackets 72 that are preferably mounted on the side 'rails R in a plane above that of the sill S. It is noted that the brackets 72 may, in some installations, be mounted on the building adjacent the rails, or if desirable, on the guide tracks to be described.
The most important feature of the invention resides in the novel means provided for supporting the bar 54 in the rolled-up and awning dispositions of the curtain; for facilitating the lowering and subsequent raisingoperations of the curtain from and to the rolled-up disposition thereof; and for protecting the lowered curtain against'wind hazards.
The means referred to are incorporated in a pairof guide tracks generally designated 74 that are mounted by means of screws 76*on'the' side rails R of the window frame F. As best seen in Figure 6, these guide tracks extend from the lintel portion L of the frame to a plane preferably a short distance above the sill S. With particular reference also to Figures 7 and 11, it is noted that the tracks are channel-shaped, and include spaced leg sections 78 and 80 connected-by a web section 82. The sections 78 and 80 are spaced apart a distance slightly greater than the diameter of the slat interlocking connections 28, so that as will appear, free but automatically controlled vertical movements of the curtain may be had. As clearly shown in Figure 6, the tracks are positioned with their channels opening toward one another, and are so mounted that they will overlap the side edge portions of the curtain when the latter is lowered.
At the top, each track terminates in a resilient clip or loop segment 84 that is illustrated as being integral with section 80, and an arcuate segment 86 that is illustrated as being integral with section 78. It is to be understood of course that, whereas the guide tracks 74 and the clip and arcuate segments thereof are illustrated as being of integral construction, the clips 84 and the segments 86 may obviously be formed separately and then integrated with the tracks by welding or otherwise.
The resilient loop segments 84 are diametered to snugly embrace the projecting ends 56 of the bar 54, and as most clearly demonstrated in Figure 11, terminate in reversely curved extremities 88 to form relatively narrow entrance openings 90 leading into the loop segment.
As particularly demonstrated in Figure 11, the spaces obtaining between the uppermost edges of the leg sections 78 and the thereabove terminal edges of the reversely curved extremities 88 are of less extent than the diameter of the bar 56, for a reason to appear.
A modified arrangement for the upper ends of the tracks 74 appears in Figures 16 and 17. In accordance with the concept there illustrated, a semicircular web segment 92 connects the leg segments 78 and at the top, and the resilient clip for engaging one of the projecting ends 56 of the bar 54 comprises a leaf spring 93. The lower end portion 94 of said spring is secured, by screws or the like, to the outer face of the leg segment 78. The free upper end portion 95 of the spring is of arcuate configuration and projects through an elongated slot 96 provided therefor in said leg segment to form an entrance opening as shown.
Operation Although it is believed that the procedure necessary to operate the invention should be evident from the foregoing description and an inspection of the drawings, a brief explanation will be given.
The combined shutter and awning assembly 20 would be installed with the parts disposed as in Figures 1 and 4. Thus, the arms 64 would be perpendicular or approximately so, depending on the length of curtain wound about the cylinder 32., The projecting ends 56 of the rod 54would each be lodged in one of the loop segments 84. At this time the windup mechanisms 36 would be disposed as illustrated in Figure 14. Inasmuch as these wind-up mechanisms constantly tend to rotate the cylinder 32 in a clockwise direction (as viewed in Figure 1), the rod ends 56 cannot be displaced from engagement with the loops 84.
Assuming now that it were desired to employ the invention in awning capacity, the draw cord 62 would be pulled downwardly causing the cylinder 32 to rotate counterclockwise. I Consequently the curtain 22 would be unwound, as the arrns 64 swing outwardly from the frame F. When the desired length of curtain has been unwound, the cord 62 would be fastened to the hook 63, thus maintaining the curtain taut, as demonstrated in Figures 2 and 5. It is to' be observed that during this entire operation, the rod 54 is positively retained in place by the loop segments 84, because the pull of the curtain is always away from the clip opening 90. In other words, during the movement of the curtain 22 and arms 64 to extended awning position, the rod ends 56 would simply spasms" semblyto the normal Figure 1 disposition, it would only be-necessary to unfasten the cord 62, whereupon the cyIinder 32 would be free torota'te clockwise again, thus ail tomatically winding up the curtain together'withthe. draw cord; It is to be observed that duringthis entire return operation, the rod ends 56 simply move in a counterclockwise direction, butdisplacementof them is prevent edby the reversely curved formations of. the segments In Figures 3 and 6, 11116;3SS6HJb1Y 20is illustrated as it would appear whenservingaas ashutter. With attention directed also to Figures 9 and 10,- the simple procedure required to dispose the-assemblyin shutter status plained. A direct downward pull on the drawstring.58,"
however, would effect escape of the rod 54 via the. openings 90, inasmuch as the reversely curved extremities 88 are distensible. p I
Assuming that the rod 54*had been thusreleased,..the curtain-would begin to'unwind from the cylinder in response to continued downwardmovement of the drawstring, as suggested in Figure 10. When the curtain had been lowered to cover the window, the ring 62'would be slipped over the hook-63thus maintaining the curtain iushutter status. 7
During the downward movements of the curtain, the projecting rod ends 56-and the marginal sideportionsof the curtain 22 would-ride'in the guide tracks 74, the seg-. ments 78 and 80 serving asrails forthe slat interlocking connections 28.
Obviously, as the curtain continues its descent, the diameter of the rolled-up slats on the cylinder continues to decrease, sothat during the final stages, thecurtain enters the tracks at an angle, as suggested in Figure 3. Such entry is facilitated by the-provision-of the arcuate segments 86; Because the cylinder 32 is constantly biased to rotate in a clockwise direction, any slack in the curtain will be taken up'autoinati'cally. Inthe' shutter status 'of the assembly; the windu'p mechanisms-36 would alsobe disposed approximately'as shown 'iIYEigure's' 12 and13. y
Assuming now that it were desired to return the curtain to its Figure 1 or normal disposition, it would only be necessary to remove the ring 60 from engagement with the hook 63. Thereupon the curtain would automatically rise with sufficient momentum to cause the rod ends 56 to re-enter the loop segments 84 via the openings 90, the reversely curved segments 88 being again momentarily distended. As the rod ends 56 approach the segments 88 near the end of the upward movement of the curtain, they are riding along the inner faces of the track segments 78, as should be apparent. It is noted, however, as previously mentioned, that the spaces between the upper edges of said track segments and the terminal edges of said reversely curved segments 88 are too small to permit the escape of said rod ends.
With respect to the modified construction appearing in Figures 16 and 17, it is not deemed necessary to repeat the mode of operation. Were the arrangement disclosed in these two views incorporated therein, the invention would be operable in the identical fashion described.
In view of the foregoing description augmented by an inspection of the drawings, it should be manifest that the present invention provides a novel construction that may be readily installed, and thereafter operated with ease.
Whereas the preferred embodiment and one modification have been illustrated and described, the invention may admit of other structural changes'witho ut departing from its scope as set forth in the claims.
