Abstract
ABSTRACT OF THE DISCLOSURE
This invention is an improvement over my U.S. Patent No. 4,326,577 issued April 27, 1982 for a window screen arrange-ment comprising a novel roller combination for winding and un-winding the screen or shade element and at the same time posi-tioning of the entire screen assembly in a desired position vertically on a window to provide partial screening in any part of the window while at the same time permitting additional screen-ing provided by the operation of the screen upon a roller. The method of supporting the screen in the window opening comprises a novel arrangement of cords for support and positioning which permit the foregoing without the use of pulleys, springs, counter-weights, hooks, clamps or other positioning devices to hold the screen assembly in any given location by permitting its roller features to function. The arrangement used here entails the use of only two instead of four cords as in my previous in-vention and by means of the novel continuous arrangement of the cords it simplifies the construction and permits positioning of the rollers at an angle to the window frame from the hori-zontal. I also provide a novel method of fastening the screen upon the rollers.

Description
The presen-t in~en-tion realtes to a vertically posi-tion-ing window installation including a window frame provided with a shading system.
The basic idea of positioning a roller type of window screen vertically in a window frame to change its effective area of screening is old in the art. Various devices have been patented and those known to the applicant at the time which are considered to be -the closest prior art are summari~ed briefly below.
~ 1 ~
..
Thiel, U.S. Patent No. 394,737, issued Dec. 1888, utilizes an ordinary roll-up type of window shade and instead of mounting it at the top of the window opening provides for its riding on guide rods at the sides of the window with a pulley and rope arrangement to raise and lower the screen ro]ler to any desired posi-tion.
Brown, U.S. Paten-t No. 938,207, issued October 1909, teaches the use of angle iron brackets at the sides of the win-dow providing rails from which L-shaped pla-tes are permit-ted to ride, said pla-tes holding the roller in position which may be altered by the use of suitable rope and pulley arrangements mounted on -the window frame and at-tached to the sliding slide plates holding the roller.
Joseph, U.S. Patent No. 1,303,678, issued April l91g, -teaches the use of horizontal metal slats to hold -the screen rol-ler which are positioned vertically in the window screen by means of chain and sprocket combina-tions, provisions being made to hold the chain in a given position and consequently provide for changing the loca-tion of -the roller.
Heck, U.S. Patent No. ~,202,395, issued October 1980, utilizes vertically movable bars wi-th zig-zag panels in between, the bars being changeable in loca-tion by means of parallel cords which in turn cause the bars to act on -the slats after -the manner somewhat of a venetian blind. The cord arrangement is of paral lelogram configuration and is very different from the arrangement of applicant.
Hopkins, U.S. Patent No. 785,806, issued March 1905, uses a hollow roller through which cords pass connecting with sliding crossheads moving in vertical grooves which hold the roller and hence the shade in a proper horizontal position.
My U.S. Paten-t No. ~,326,577, issued April 27, 19~2, utilLzes hollow rollers and tension cords so arranged in or upon J~
a window frame as -to remain in tension at all -times and hold -the rollers in any given desired position because of their novel me-thod of -threading through the rollers and attaching -to -the frame. In that invention, I use two sets of cords of two each or a total of four which somewhat complicates -the tension adjust-ment of the cords.
- 2a -'f~
My improved screen and roller combination, as my previous invention as disclosed in U.S. Patent NoO 4,326,577 issued April 27, 1932, departs from -the traditional screen arrangement using two rollers from which the connecting screen is rolled and unrolled to change the area oE screening. The rollers and hence the screen is supported in any desired position by a novel and improved cord arrangement which permits the entire screen to be raised and lowered by changing the position of the upper roller and the screen opening is altered by rotation of the lower roller wl-thout the necessity of any positioning devices such as pulleys, chains, ropes or springs. My novel and improved construction provides for the support cords to be threaded through the rollers and over and around the window frame back to anchor positions at the base of the window main-taining tension on the cords and hence holding the rollers in any given position, including a position at an angle to the horizontal roller and permitting ready removal for cleaning~
etc.
According to the present invention therefore there is provided a vertically positioning window ins-talla-tion including a window frame provided wi-th a shading system comprising: a :ti.rst upper hollow non-rotating horizon-tal roller; a second lower hollow rotating roller parallel to said .Eirst roller; a vertical screen having one of its parallel horizontal edges fixedly positioned upon said first roller and its opposite edge fixedly positioned on said second roller; a first cord means having its ends fixedly positioned on opposite sides of the lower edge of a window frame; said first cord means being disposed to suspend said first roller through its hollow center while permitting a vertical movement of translation of said first roller along said first cord means; a second cord means having its ends fixedly positioned on the opposite sides of the lower edge of said window frame; said second cord means being disposed to suspend said second roller through its hollow center while permitting a combined movement of ro-tation and translation of said second roller; said first roller being equipped with a respective cap at each end, each of said caps having a pair of holes positioned one above -the other drilled through them; said second roller being ecluipped with a respec-tive cap at eaeh end, each of said caps having a hole drilled through it coneentric to said roller; said first cord means passlng from one side of said lower edge of said window frame in turn through the lower of said holes i.n the first end of said first roller, thence through -the interior of said first roller, thence through the upper of said holes in a second end of said first roller, thence vertically upwards to the -top of said window frame to a firs-t holding means positioned thereon, thence horizontally across the top of said window frame to a second holding member positioned thereon, thence vertically downward to the upper of said holes i.n said first end of said first roller, thence through the interior of said firs-t roller, thence through the lower of said holes in said second end of said first roller, thence vertically downward to the opposite side of said lower edge;
said second cord means passing in turn from one side-of said lower edge of said window in turn through the coneentric hole in the firs-t end of said second roller, thence through the interior of said second roller through the concentrie hole in a second holding member, thence ver-tically downwards to said a second end of said second roller, thence vertically upwards to the top of said wlndow frame to a first holding member, thence horizontally across the top of said window frame to said second holding member, thence vertically downwards to said concentric hole in said first end of said second roller, -thence through the - 3a -~¢3~
interior of said second roller through sald concen-tric hole in said second end of said second roller, t~lence vexticall~ down-wards to the opposite side of said lower edge.
The present invention will be further illustrated by way oE the accompanying drawings, in which:
Fig~ 1 is a front elevation of a window frame showing my system installed inside the framei Fig. 2 is a schematic diagram for better understanding of the improved method of installing my cords which comprise 10 the heart of the operating system;
Fig. 3 is a partial isometric showing the top of a win-dow frame with my improved system installed on its outer face;
F'ig. ~ is an end view of the angle bracket for turning and holding the cords when used inside the frame as in Fig. l;
~ ig. 5 shows the adjustable knob for turning and holding the cords when the system is installed on the face of a window frame as in Fig. 3; and Fig. 6 shows a roller with my improved method of fastening the screen to the roller.
- 3b -Referrlng now to the Figures and especially first to Fig. 1, there is seen a typlcal window frame 1, a screen 2, the upper roller 3 of my system and the lower roller 4. The ends of screen 2 may be fastened -to rollers 3 and 4 respectively by any suitable means such as a "Velcro" (-trademark) fasteners or by the preferred method whic~l I descxibe below and is illustrated in Fig. 6.
A-t -the ends of roller 3 are positioned knobs 9 which form a part -thereof. In each of knobs 9 -there is drilled an upper hole lOa and a lower hole lOb, -the function of which is set forth below. On roller No. 4 are posi-tioned knobs 11 a-t the end of which are drilled concentric holes 12 whose func-tion is also se-t for-th below. Angle brackets or hooks 13c in Fig. 1 or 13b in Fig. 3, which are shown in greater de-tail in Figs. 4 and 5, respectively, are positioned a-t the top of the frame for passage and holding of the cords. The ends of the cords are secured by any sui-table fas-tening means a-t the bo-ttom of the frame as shown at 14.
Atten-tion should now be given to Fig. 1 in conjunction with Fig. 2 to understand the method of ins-talling my opera-ting cords. In this improved embodiment I use -two separate cords designated as l5a and 15b. S-tarting firs-t with cord 15a from its arlchor point in Fig. 14, I rise vertically to hole lOb in the knoh 9 of roller 3. I pass -through the interior of this roller and out the opposite end -through -the upper hole lOa and then upwards to my angle bracke-t or -turning knob, as the case may be 13b or c. I then proceed hori70ntally across the -top of the window frame 1 to -the opposite side and again around the angle bracke-t or knob 13b or c downwards to the upper hole lOa in knob 9 on roller 3. I pass through the interior of this roller and out through the lower ho]e lOb on the opposite end and thence downward to the anchor point 14 at the bo-ttom of -the window frame.
Now turning our attention to -the second cord designa-ted as 15b, I again star-t from anchor point 14 and go upwards -to concen-tric hole 12 in knob 11 -through roller 4 and out the opposi-te end, again -through concentric ~lole 12 and thence upwards to -turning bracket or knob 13b or c, -thence horizontally -to the corresponding -turning knob or bracke-t on the opposite side of the window frame, thence downward again -to concentric hole 12 in knob 11 through roller 4, ou-t the opposite end of roller 4 through concentric hole 12 and back down to anchor point 14. The cords are all held in sui-table tension by anchor means 14.
tt is -thus seen -tha-t with this improved embodiment I
need use only two cords which simplifies -the matter of main-tain-ing proper tension. Because of the essen-tially single cord arrangement of 15a I am able -to tilt roller 3 at any ang]e desired from -the horizontal and s-till main-tain tension on -the cords.
Looking a-t Fig. 4, -there is seen the angle bracket 13c of Fig. 1 having holes 33 for fas-tening the window frame 1 and a slot 32 for passage of -the cords.
In Fig. 5 there is seen a detail of my knob 13b of l`ig. 3 which is screwed in-to the window frame as shown by means oE hex nut 34. Washer 35 and acorn nut 36 serve -to hold the cords in fixed posi-tion when proper tension has been established.
Referring now to Fig. 6 there is seen one of my rol-lers, either 3 or 4, with its knobs 10 or 11. In this embodimen-t -these knobs are equipped wïth an additional hole 62. The rol-lers in this case are equipped wi-th a longitudinal slo-t 63 through out their length positioned opposite hole 62. My screen

The present invention will be further illustrated by way oE the accompanying drawings, in which:
Fig~ 1 is a front elevation of a window frame showing my system installed inside the framei Fig. 2 is a schematic diagram for better understanding of the improved method of installing my cords which comprise 10 the heart of the operating system;

~ ig. 5 shows the adjustable knob for turning and holding the cords when the system is installed on the face of a window frame as in Fig. 3; and Fig. 6 shows a roller with my improved method of fastening the screen to the roller.
- 3b -Referrlng now to the Figures and especially first to Fig. 1, there is seen a typlcal window frame 1, a screen 2, the upper roller 3 of my system and the lower roller 4. The ends of screen 2 may be fastened -to rollers 3 and 4 respectively by any suitable means such as a "Velcro" (-trademark) fasteners or by the preferred method whic~l I descxibe below and is illustrated in Fig. 6.
A-t -the ends of roller 3 are positioned knobs 9 which form a part -thereof. In each of knobs 9 -there is drilled an upper hole lOa and a lower hole lOb, -the function of which is set forth below. On roller No. 4 are posi-tioned knobs 11 a-t the end of which are drilled concentric holes 12 whose func-tion is also se-t for-th below. Angle brackets or hooks 13c in Fig. 1 or 13b in Fig. 3, which are shown in greater de-tail in Figs. 4 and 5, respectively, are positioned a-t the top of the frame for passage and holding of the cords. The ends of the cords are secured by any sui-table fas-tening means a-t the bo-ttom of the frame as shown at 14.
Atten-tion should now be given to Fig. 1 in conjunction with Fig. 2 to understand the method of ins-talling my opera-ting cords. In this improved embodiment I use -two separate cords designated as l5a and 15b. S-tarting firs-t with cord 15a from its arlchor point in Fig. 14, I rise vertically to hole lOb in the knoh 9 of roller 3. I pass -through the interior of this roller and out the opposite end -through -the upper hole lOa and then upwards to my angle bracke-t or -turning knob, as the case may be 13b or c. I then proceed hori70ntally across the -top of the window frame 1 to -the opposite side and again around the angle bracke-t or knob 13b or c downwards to the upper hole lOa in knob 9 on roller 3. I pass through the interior of this roller and out through the lower ho]e lOb on the opposite end and thence downward to the anchor point 14 at the bo-ttom of -the window frame.
Now turning our attention to -the second cord designa-ted as 15b, I again star-t from anchor point 14 and go upwards -to concen-tric hole 12 in knob 11 -through roller 4 and out the opposi-te end, again -through concentric ~lole 12 and thence upwards to -turning bracket or knob 13b or c, -thence horizontally -to the corresponding -turning knob or bracke-t on the opposite side of the window frame, thence downward again -to concentric hole 12 in knob 11 through roller 4, ou-t the opposite end of roller 4 through concentric hole 12 and back down to anchor point 14. The cords are all held in sui-table tension by anchor means 14.
tt is -thus seen -tha-t with this improved embodiment I
need use only two cords which simplifies -the matter of main-tain-ing proper tension. Because of the essen-tially single cord arrangement of 15a I am able -to tilt roller 3 at any ang]e desired from -the horizontal and s-till main-tain tension on -the cords.
Looking a-t Fig. 4, -there is seen the angle bracket 13c of Fig. 1 having holes 33 for fas-tening the window frame 1 and a slot 32 for passage of -the cords.
In Fig. 5 there is seen a detail of my knob 13b of l`ig. 3 which is screwed in-to the window frame as shown by means oE hex nut 34. Washer 35 and acorn nut 36 serve -to hold the cords in fixed posi-tion when proper tension has been established.
Referring now to Fig. 6 there is seen one of my rol-lers, either 3 or 4, with its knobs 10 or 11. In this embodimen-t -these knobs are equipped wïth an additional hole 62. The rol-lers in this case are equipped wi-th a longitudinal slo-t 63 through out their length positioned opposite hole 62. My screen
2 is made with a hem 64 -to accommodate a sliding rod 61. Wi-th this embodimen-t I insert my hemmed end 64 of screen 2 into slo-t 63 and then insert rod 61 -through -the hem of screen 2 -through i-ts entire length and then out the hole 62 at -the opposite end. This serves to offer a positive engagemen-t be-tween the edge of screen 2 and the roller 3 or 4 and at the same time makes it readily removable for washing or cleaning of the screen 2.
The opera-tion of my system is essentially -the same as that in my V.S. Patent No. 4,326,577. Upper roller 3 is placed in the highest possible position in window frame 1 by merely physically moving the roller upwards with -the mo-tion of -transla-tion, -the cords 15a sliding -through the hollow interior of roller
The opera-tion of my system is essentially -the same as that in my V.S. Patent No. 4,326,577. Upper roller 3 is placed in the highest possible position in window frame 1 by merely physically moving the roller upwards with -the mo-tion of -transla-tion, -the cords 15a sliding -through the hollow interior of roller
3 while main-taining -tension -throughout -the system. Screen 2 is then attached -to roller 3 by any suitable means men-tioned above, preferably the one illus-trated in Eig. 6. Screen 2 is -then stretched out its full length and its lower edge engaged on rota-ting roller 4, also by means of sui-table fastening means as des-cribed above. To change -the effec-tive screen leng-th of screen 2, bottom roller is -then merely rotated by hand causing the screen to wind up upon its perime-ter. When thus shortening the screen, the rol]er 4 will move upwards and -the cords 15b being concen-tric will permi-t this movement upwards along the length of the cords while main-taining -tension against the anchors 14. Any 2() des;red amount of screening may be obtained depending upon how m~lch tlle screen is rolled up on roller 4.
To position the screening area vertically in -the win-down opening in order to locate -the effective screening area in the desired elevation, roller 3 is grasped and is physically moved upwards and downwards with a motion of translation. :[n this case cords 15a passing -through holes lOa and 10b and a hollow interior roller 3 slide through the roller and maintain its posi-tion because of the tension and friction of the cords brough-t about by their passage through -the hollow interior of roller 3 and the tension maintained by anchors 14. In this man-ner any desired amount of window area may be screened and -the location of the screened area positioned ver-tically a-t any ~35~
desirable point, the .rollers 3 and 4 being maintained in posi--tion by the action of -the cords.
The effectiveness and simplicity of opera-tion of my system and its construction are now evident, as well as its construction are now evident, as well as i-ts novely and su-periority over the prior art through -the absence of elaborate sys-tems of pulleys, ropes, springs and o-ther devices as se-t forth above, all of which I elimina-te.
