United States Patent O ROLLAWAY SCREEN David A. Barry, Joliet, Ill.
Application June 13, 1955, Serial No.l514,904 1 Claim. (Cl. 160-269) 'Ihis invention relates generally to screen constructions and is more particularly concerned with a rollaway screen usable at various openings being screened whereby said screen may be readily installed and is highly eiective to prevent the entrance of insects into an area being screened or be used to enclose garage or similar large openings.
The principal object of invention in conformance with that set forth above is to provide a reticulated flexible screen member which is operatively secured to a roller assembly on its transverse upper edge portion, removably received in side guide cam clamp members, which includes a lower sealing flap for preventing the movement of insects thereby.
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 accompanying drawings forming a part hereof, wherein like numerals refer to like parts throughout, and in which:
Figure lis a front elevational view of the rollaway screen construction positioned in a building opening being screened, the walls of the building being shown in section;
Figure 2 is an enlarged sectional view taken substantially on line 2-2 of Figure l Figure 3 is an enlarged sectional view taken substantially on line 3 3 of Figure l;
Figure 4 is an enlarged lsectional view taken substantially online 4--4 of Figure 1; and
Figure 5 is an enlarged sectional view taken substantially on line 5-5 of Figure l.
A building is indicated generally at an'd includes an opening indicated generally at 12 which is formed by side frame members 14 and 16, a transverse top frame member 18 and a bottom frame portion 20.
The rollaway screen is indicated generally at 22 and includes a transverse roller assembly 24 extending transversely across the upper edge portion of the opening 12 being screened, and comprises an elongated rectangular housing member 26 which has a back wall portion 28 secured by means of suitable fasteners 30 to the top frame member 18,-see Figure 4. Extending the length of the housing member 26 and secured to the end walls thereof is a support rod 32 which has rotatably journalled thereon a tubular roller 34, said rod 32 having concentrically disposed thereon a coil spring 36 which has one end 38 secured to the rod 32, the other end being secured to the roller 34. A reticulated ilexible screen member ofy any suitable material, such as galvanized wire, copper, etc., is indicated at 42, the upperedge 44 thereof being secured by means of suitable fasteners 46 to the roller 34, the screen 42 extending from a bottom member 48 of the housing 26 through a transversely extending slot portion 50. Thus it will be seen by pulling the screen 42 downwardly as indicated by the arrow in Figure 4, will result in the coil spring 36 being wound around the shaft 32 ICC whereupon release of the screen 42 will result in the spring 36 tending to return the shaft 32 and tubular sleeve 34 to an original relatively fixed position.
As seen in Figure 5, extending along the lower edge of the screen member 42 is a suitable flat member indicated at 52 which may be of rubber or any other exible material and which is molded along the lower edge 54 of the screen member 42, said flat member including an outwardly extending fastening ring 56 which may be engaged by a suitable hook member or flexible cord in portion 20 forming the opening being screened.
. The side edges 58 of the screen member, see Figure 2, are bound by a exible binding material 60 such as canvas, said binding material extending about an edge forming bead element 62 which may be rope, exible wire cable, etc., the canvas being secured to the screen member by means of sewing, staples, as seen at 64.
Secured on the side frame members 14 and 16 are vertically disposed side rail assemblies 66, each of which including a rst angle bar member 68 which will be called the rear angle bar member for purposes' of description, which includes a leg 70 secured by means of fastening elements 72 to the side frame member 16, for example, and includes an outwardly extending leg 74 engageable with one side of the edge of the screen member 42 adjacent the canvas portion 60 and the bead forming elements 62. Secured in spaced relationship to the leg 74 of member 68 are a plurality of vertically spaced journal block elements 76 which are secured to the side frame member 16, for example, by means of suitable fasteners 78, see Figures 2 and 3. The blocks 76 support on an upper surface portion 80 in leg 82 of a second or forward angle bar member 84 which includes an outwardly extending leg portion 86 which is movable toward and away from the leg portions 74 of the angle bar members 68 and which is engageable inwardly of the bead portion 62 of the screen member 42 and thereby clamp said screen between the legs 74 and 86. The elements 76 include a suitably recessed portion 88 which rotatably supports a pivot shaft 90 which includes an enlarged lower end portion 92 for preventing the removal thereof, said shaft 90 extending through an elongated horizontal slot portion 94 contained in the leg 82 of the angle bar member 84, said shaft`90 terminating in a right angular handle portion 96. The shaft 90 has secured thereon above the upper surface 98 of the leg 82 of the angle bar member 84, an annular cam member 100 which includes an eccentric convex portion 102 which is engageable with the outwardly extending ange portion 86 of the angle bar member 84 and which is operable to move said angle bar member toward and away from the previously mentioned leg 74.
Thus it is believed readily apparent that by movement ofthe handles 96 and the previously mentioned adjustable angle bar member the bead 62 of the screen member can be inserted between the members 68 and 84 and the screen may be pulled downwardly against force of the spring 36 when secured in the position shown in Figure l. Release of the fastening element 56 from whatever means is provided to hold the screen in the position shown will result in the spring urging the screen into the roll position as seen in Figure 4, the resilient flap element will engage the lower portion of the housing member 26 adjacent the slot 56 and will be accessible providing a handle means by which the screen may be subsequently pulled down into the previously mentioned position of Figure l. r[he ilat member 52 will be urged into resilient contact with the portion 20 forming the opening being screened and accordingly will prevent the ingress of insects thereby.
Various positional directional terms such as front, rear, etc., are utilized herein to have a relative con- Patented July 29, 1958 3 notationto aid in. describing the device, and they are not intended to require,4 any particular orientationwithrespect to any external elements.
The foregoing is considered as illustrative only of the principles of the invention: Further, since numerous modifications and changes willl readily occur to those skilled in the art, it is not desired to limit the` invention to that exact construction andoperation shown and described, and accordingly all suitable modifications and equivalents may be resorted to', falling Within the scope ofthe invention as claimed.
What is claimed as new is asi follows:
A rollaway screen construction for an opening between vertical side members comprising a spring tensionedhorizontal roller at the top lof said opening, a exible` screen member for closing said opening having side edges adjacent said side members and an upper edge attached to said roller for rolling of said screen on said roller to raise said screen member, pairs of vertical angle bars at each side edge of the screen member at opposite sides of the screen member for guiding said screen member during raising' thereof7 the bars of the pairs at one side of the screen member being fixed to said side members, vertically spaced blocks on each side member at the opposite side of the screen member, rotary crank handle shafts journaled in said blocks and on which the other angle bars of the pairs are slidable laterally for clamping the side edges` of said-v screen member between the angle bars yof the pairs, and cams on said shafts rotatable thereby against said other angle bars for sliding the latter laterally said other angle bars having transverse slots therein through which said shafts extend and which slidably guide said other angle bars.
