Variable Viewing Window Shade/Awning System

Abstract

A fabric window shade/awning system or assembly having two (2) cordless overlapping panels that can be adjusted to vertically create an opening within the wall of an enclosure. The window assembly is fabricated and all adjustments are done inside the enclosure. The bottom/inside panel is permanently attached along its bottom to the wall, the top/outside panel, vertically overlapping the bottom panel, is permanently attached at the top and being part of the wall. Both panels, each, have zippers along each of its side margins and assembly/wall. The top/outside panel has fabricated pockets, of like material, with inserted constant-force coiled steel springs to create an awning, within the top panel, when relaxed. To create an opening, the bottom/inside panel is first unzipped allowing it fall, by gravity, then the top/outside panel raises, when unzipped, due to the relaxed constant-force coiled springs to define/create a desired concealment and an opening for a field of view through such window assembly. The top panel awning helps prevent rain from entering the outdoor enclosures used in the field of this invention being hunting blinds, wildlife viewing/photography blind, camping tents, craft/event tents, military, and etc.

Description

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a fabric window shade system or assembly for fabric enclosures. This window assembly will provide maximum concealment and the same time the ability to incrementally adjust the window opening's vertical size and/or the opening's height from the floor within the enclosure. This invention is for concealed enclosures used in hunting, wildlife viewing/photography, camping, military, and etc., needing a wide adjustable range of concealing/viewing window assembly. This invention also provides an integrated awning within the top/outside panel to help prevent rain from coming through an opened window assembly.

2. Description of the Prior Art

The patent literature is replete with prior art relating to cordless mechanisms for opening window shades, U.S. Pat. No. 6,079,471, (to Kuhar, issued Jun. 27, 2000), being representative thereof. In the Kuhar shade, the mechanism for opening and closing of shade employs constant force, or consistent, variable force spring motors, wound on drums, whereby spring force imparted to a coiled spring is transferred from one drum to another. The spring motors are capable of winding the drum and thereby retracting the shade which is attached to the drum. The Kuhar blinds and shades of may be manipulated by the operator simply grasping the bottom bar and urging it in an upward or downward direction.

The cordless winding drum concept, with minor variation, is also depicted in U.S. Pat. No. 6,056,036 (to Todd et al, issued May 2, 2000—Cordless Shade concept); and, in U.S. Pat. No. 6,283,192 (to 8, issued Sep. 4, 2001—Flat Spring Drive Mechanism concept).

The patent literature is also replete with prior art relating to multiple, or dual panel shades, wherein each of the panel of the compound shade can be operated independent of the other, U.S. Pat. No. 4,953,610, (to Phillips et al. issued Sep. 4, 1990). The Phillips et al describes a compound or dual panel shade, wherein each panel within the compound shade are located in a front-to-back relationship, and can be independently opened and closed relative to the other. In Phillips et al, the front shade is made of a substantially translucent or light passing material while the back shade is made of a substantially opaque or light blocking material. The user of the window shade assembly is able to adjust one or both of the front and back shades to control where outside light is able to pass through the assembly including the amount of outside light that passes through the front shade or passes directly into the room without passing through the front shade.

The patent literature also discloses dual shade applications, in a top down, bottom up, compound shade, U.S. Pat. No. 4,813,468 (to Fraser issued Mar. 21, 1989). In the Fraser concept, each of two independent panels within a compound shade can be opened and closed, one from the top down. Dual shade applications, in a top down, bottom up, compound shade, are also disclosed in U.S. Pat. No. 6,164,362 (to Yang issued Dec. 26, 2000—Top Down-Bottom Up Shade Having An Improved Lift System); and, in U.S. Pat. No. 7,063,122 (to Colson et al, issued Jun. 20, 2006—Bottom-Up/Top-Down Retractable Cellular Shade). A top-down retractable shade is understood to refer to a shade that is closed when extended from the top of a window to the bottom of the window; and, conversely, a bottom-up retractable shade is closed when extended from the bottom of the window to the top of the window.

In each of the embodiments described hereinabove, the contemplated environment for application of these concepts requires installations of such blinds/shades in a more or less permanent and protected structure, which isolates the cordless retraction mechanism from exposure to the elements in a more rugged, outdoor environment. Accordingly, the adaptation of the above concepts (cordless retractable shades, variable force spring motors, and top down, bottom up, compound shades), has been impractical for implementation in camping equipment (tents) and in portable hunting blinds. More specifically, up to now, the mechanism used for securing a “shade” over the covering of “window-like” openings in such portable structures, has been with a loop & hook (Velcro) closure and/or a zipper.

The following patents is illustrative of the loop & hook (e.g. Velcro) fastener for securing a removable flap to an opening in a hunting blind, U.S. Pat. No. 5,813,160 (to Thoelke issued Sep. 29, 1998—Portable Hunting Blind). In Thoelke, the window in his hunting blind is provided with a removable flap that is secured over a “window” with a loop & hook (e.g. Velcro) fastener (FIG. 14. Ref no. 104). Thus, the hunter desires to open the blind “window”, he must manually remove the flap (ref. no. 104) from the outside of the blind. Once the flap is removed, it must be separately retrieved and stored to prevent it from being lost. Moreover, once removed and the window opened, the interior of the blind and hunter is now exposed to the elements (rain and wind).

Up to now, almost all concealing enclosures have a one (1) panel window assembly which is moved vertically, usually from the top down. This allows only a change in the opening's vertical size, and can cause a large unconcealed area within the window opening. And, these (1) panel window assemblies do not allow user to select a vertical opening size and then change the height of that opening in respect to the floor of an enclosure. Moreover, none of the portable enclosure has up to now been capable of adaptation of a fabric window assembly with an awning for rain protection in such portable enclosures. The ability to adapt mechanism in such portable enclosure windows has up to now been impractical (do to their inherent complexity), and the lack of durability thereof in an unprotected/outdoor environment.

Similarly limitations exist for the more traditional windows, specifically, the inability to provide an adjustable multi-panel system to shade/panel cover a window opening wherein the field of view through the window is infinitely variable, based upon the relative position of the adjustable panels, relative to one another.

OBJECTS OF THE INVENTION

With the above related art in mind, the primary object of this invention is to provide a variety of fabric enclosures with a cordless, concealing, (2) vertically overlapping shade/panel window assembly with the ability to adjust both a desired vertical opening size and the ability to vary the vertical height of that desired vertical opening, from the floor of a said enclosure.

More specifically, in the above and related primary object of this invention is to provide a window shade system or assembly having (2) cordless, concealing, adjustable, overlapping, vertically movable shade/panels within the window assembly, which are incrementally adjustable by the use of zippers. The (2) panels are independently adjusted, each having a set of zippers. The vertical position of each panel is relative to each other, within the window assembly, to effect the concealment and define/create a field of view through a window assembly.

Another object of this invention is to provide an enclosure a window shade assembly having a pair of adjustable, vertically overlapping panels which will accommodate different height users, allowing them to adjust the (2) panels to their desired height, especially in the use of hunting and wildlife viewing/photography blinds. These enclosures typically have one (1) seat, thus, the different height users in the same seat will have the ability to adjust the window opening for their height, while still keeping maximum desired concealment within the enclosure.

It is yet another object of this variable view window shade system or assembly having a pair of cordless, vertically adjustable, overlapping panels to provide each user the appropriate concealment/viewing for different situation, such as, gun hunting, bow hunting, wildlife viewing, photography, camping, boating, military, and etc.

Yet another object of this window assembly is to provide the user optimal concealment/visibility from the enclosure when placed on any terrain, changing terrain, and raised platform, by adjusting the opening for the angle of viewing due to elevation changes.

Yet another object of these windows is to provide for several window assemblies placed within the same wall of an enclosure, allowing individual adjustment for each window opening as user feel needed or desired.

Further yet, the object of these window assemblies is having several window assemblies within a given wall of an enclosure, allowing multiple users within the same enclosure at the same time to adjust their own window opening to meet their height and/or desired need.

It is still yet another object of the window assembly to provide rain protection for enclosure by having an integrated awning within the top/outside panel. The integrated awning will require a constant-force ribbon coiled steel spring to roll up the top panel.

Yet still another object of the fabric window assembly to provide like material of that used for said enclosure for concealment purposes.

SUMMARY OF THE INVENTION

The above and related objects of this invention are achieved by providing a variable concealing/viewing window system to any given outdoor enclosure. The primary usage of the window assemblies are for fabric portable blinds such as for hunting and wildlife viewing/photography. This variable concealing/viewing window assembly concept can also be used in camping tents, event tents, boating fabric enclosures, military needs, or basically an enclosure. Each window assembly is comprised of (2) cordless, vertically moving, overlapping fabric panels. Typically, the window assembly is to be of like material/fabric as the enclosure. The typical, rectangular shape window assembly opening size is 4 inches to 16 inches wide/horizontally and 15 inches to 18 inches high/vertically. The added integral parts on the top panel are pockets with constant-force springs sized in length, approximately the same vertical length of the top panel, to meet the need of creating the awning within the top panel. The window assembly can be irregular in shape, triangular, within functional reasoning. The window assembly is integrated within a given wall on the inside surface, with the top/outside panel being an actual part of the interior of said wall. The top/outside panel is fixed along top, being part of the wall of which it exists. The top panel has an integrated awning. In this preferred embodiments of this invention, the retraction of the top/outside panel provides an “awning effect”, thereby preventing rain from washing down from the exterior of the enclosure, through the window and into the interior of the enclosure. The bottom/inside panel is permanently attached/sewn along its bottom edge to the outside surface of the wall just below the fabricated assembly opening. Both panels are attached, at their respective two vertical sides/margins to the wall by means of zippers, half on the side edges of each panel, the other half of zipper onto the wall. The top panel is vertically zipped closed (extended), from top to bottom. The bottom panel is vertically zipped closed (extended), from bottom to top. The awning is formed within the top panel by means of a vertical pocket sewn on inside surface of panel where needed, typically next to each lateral margins zipper and have a thin metal ribbon constant-force spring inserted into each vertical pocket. All functions of this window assembly are accessible inside any said enclosure. In the case of transporting a portable blind/enclosure, it would be practical to remove each constant-force spring.

The independent relative movement of the panels within the assembly can create, or define, a field of view through said window assembly, and thereby a variable field of view through said window can be determined by the position of each of the moveable panels within the frame/wall, relative to one another. Any opening's vertical size can be virtually anywhere between a fully closed window to a fully opened window and anywhere in between.

Because the panels within the assembly move in a vertical plane relative to one another, the variable field of view through said window creates a site window or opening therein, along their vertical plane of movement. The relative position and size of the variable field of view through the window or opening therein, corresponds to the relative vertical relative position of each panel.

Each panel can be partially opened, independent of the other, to define an opening in the window, based upon the relative position of each panel to the other. The restraining zippers on the top/outside panel are accessible from inside the enclosure and underneath the bottom/inside panel zippers, so, they must first be opened (unzipped) to permit access to the restraining zippers on the top/outside panel.

This process of incremental change in position of the top/outside panel is incrementally effected by the combination of the unzipping the top/outside panel from the wall with the constant force, flat metal ribbon springs, positioned within the vertical pockets which are integral with the top/outside panel. Insofar as the top panel, zippers, pockets, and constant-force ribbon spring are integral to one another, the unrolled restoring force of the springs are retrained by the zippers on each of the lateral margins of to the panel, when the top panel is in the closed (zipped) position. As the restraining zipper incrementally disengages (unzipped) the panel from the wall, the flat metal ribbon springs incrementally retracts/rolls up the top/outside panel and opens the window, while creating an awning.

The incremental unzipping of the bottom/inside panel, results in the bottom panel incrementally detached vertically from the assembly/wall on its lateral margins. The panel is thereby simply allowed to relax and fall down inside of the wall by the effect of gravity.

This variable view two (2) panel assembly is preferable made from an environmentally durable material, and can be opaque, transparent or any variation thereof.

DETAILED DESCRIPTION OF THE INVENTION INCLUDING PREFERRED EMBODIMENTS

The description of the preferred embodiments which follows makes reference a series of illustrative drawings, not to any scale, depicting the novel combination of elements of this invention.

In FIG. 1, a portable enclosure, in the form of a fabric hunting blind 5 is disclosed. The front wall 15 is provided with a Variable View window assembly 10, having a top panel 25 with two pockets 27, and each retaining a relaxed constant-force coiled ribbon springs 28, (inside/unseen). The top panel 25 has been relieved by unzipping zippers 26 along both sides and allowing the constant-force springs to retract top panel 25 vertically up and outward (roll up) to create an awning. Also, the bottom panel 23 has been relieved by unzipping zippers 24 (inside wall/unseen) along both sides and allowing it to full down (unseen) inside the enclosure 5 by gravity. The shown position of both the top panel 25 being fully retracted and the bottom panel 23 being fully retracted illustrates a fully opened 20 window. The above mentioned window assembly 10 is comprised of integral parts illustrated in the embodiment of FIGS. 2-5.

Shown in FIG. 2 is a constant-force steel spring 28 constructed of spring steel and treated to form a coil when relaxed having a constant force along its near entire length. In regards to FIG. 1 typically the constant-force spring 28 is made to provide necessary force to roll up the top panel 25, depending on the fabric of the enclosure 5. The length of the spring 28 is determined by the desired vertical length where-ever placed on the top panel 25. The constant-force springs 28 are meant to remain within fabricated pocket, but, would need to be removed when disassembling a portable enclosure for transporting.

FIG. 3 shows the pocket 27 that is fabricated from like material of said window assembly 10 depicted in the embodiment of FIG. 1, by conventional sewing methods. It is a folded piece of material and sewn to form a narrow pocket, just wide enough to house/retain the Constant-force spring 28, and long enough to match the vertical length of the top panel 25 necessary to create the awning. This pocket 27 is an integral part of the window assembly's 10 top panel 25 using one of more, each retaining a constant-force spring 28 to provide functional means to form the awning within the top panel 25.

FIG. 4 depicts the integral zipper 24, 26, a common used zipper for the field of this invention. Two zippers 24 are used on the two lateral edges of the bottom/inside panel 23 and two zippers 26 are used on the two lateral edges of the top/outside panel 25. Both sets of zippers 24, 26 are of length to their respective panel 23 and 25. These zippers 24, 26 provide the means for adjusting the vertical size and vertical location of the desired window opening 20 as referenced in FIG. 1.

FIG. 5 is the bottom/inside panel 23 which is fabricated of like material as the enclosure 5 depicted as in FIG. 1. It is the same vertical length as the top panel 25 and slightly wider than the top panel 25 allowing it to overlap, horizontally, the top panel 25. The construction of the bottom panel 23 is done by standard sewing methods used in the field of this invention and has a vertical cut made near the bottom corner at each side of the bottom panel 23 from the bottom up enough to form a center flap which will be equal to horizontal designed width of the window assembly's 10 opening 20. This flap is permanently attached to outside surface of the wall 15 of enclosure 5 which is shown in FIG. 1 to allow water to shed downward on the outside surface of enclosure 5.

FIG. 6 embodiment shows the integrating of components to form a window assembly 10 depicted in FIG. 1 on the inside surface of wall 15 using standard sewing methods, hems, seams, etc. for the field of this invention. First, the top/outside panel 25 is formed by making, a common rectangular shape, three cuts, within the functional area, of a wall 15 based on the field of use and the framing of enclosure 5. Commonly, Two vertical cuts being a designated distance apart equal to the desired width of top panel 25, and the length of cuts equal to the vertical length of top panel 25. As referenced in the embodiment of FIGS. 13 and 14, the shape of window assembly 10 can be irregular. The third cut is across the wall 15 from the respective bottom of one vertical cut to the other, thus creating a vertical flap in the wall 15 leaving the top as part of the wall 15 therefore, referencing the flap as the vertical top/outside panel 15/25. A zipper 26 is sewn, with dead end at the top, to each lateral margin of the top panel 25 and the created margin of the wall 15. Next, a fabricated pocket 27 referenced and defined in embodiment FIG. 3 is sewn onto top panel 25, one lateral margin directly to the panel 25, the other lateral margin of pocket 27 is sewn onto the tab of zipper 26, this being done on both sides of top panel 25. The bottom/inside panel 23 defined in FIG. 3 is made, and shown in embodiment FIG. 7, with one lateral tab of zipper 24 being sewn, with dead end at the bottom, of both, to each lateral margin of bottom panel 23. Finally, the bottom panel 23 with zippers 24 is placed, overlapping the top panel 25, with the flap at the bottom of the bottom panel 23 being sewn on the outside surface of the wall 15 and the two outside lateral tabs of zippers 24 of bottom panel 23 are sewn onto the wall 15. To complete the variable-viewing window assembly 10 a constant-force spring 28 would need to be inserted in each pocket 27.

FIG. 8 is a view from inside an enclosure 5, referenced in FIG. 1 of a wall 15 showing a fabric window assembly 10 depicted in FIG. 1 with both the top panel 25 and bottom panel 23 in their fully closed, extended position. The top panel 25 has constant-force ribbon springs 28 within the pockets 27. In this closed position, such constant-force springs 28 are under tension and in an unrolled/straight extended position by zippers 26. Each of the panels 23 and 25 are retained shut by zippers 24 and 26, respectively, being extended, each fully zipped, which connects the lateral (vertical) margins of each panels 23 and 25 to the wall, creating a fully closed window assembly 10.

FIG. 9 is a view from inside the same fabric enclosure 5 referenced in FIG. 1 of a wall 15 with window assembly 10 depicted in FIG. 1 showing both bottom panels 23 and top panel 25 in a fully retracted position, creating a fully opened 20 window, (From this point forward all embodiments referencing adjusting zippers 24 and 26 are done by user from inside enclosure 5, all this is done by, first, fully retracting, unzipping both zippers 24 of bottom panel 23 allowing it to fall down, due to gravity, exposing top panel 25 and zippers 26. Then, both zippers 26 are fully retracted, allowing the restraining force of the constant-force springs 28 within the attached pockets 27 to return to its relaxed rolled up state causing the top panel 25 to roll upward and outward to create a full opening 20 in the window assembly 10 depicted in FIG. 1 with the awing formed in the top panel 26, being outside the enclosure 5 as depicted in FIG. 1.

FIG. 10 is another view of window assembly 10 mentioned above in FIG. 9 with the opening 20 being at the top of window assembly 10 (FIG. 1). The only adjustment needed to create this opening 20 at this point is to simply extend both zippers 24 causing bottom panel 23 to raise and cover the previously fully opened 20 window. The zippers 24 are extended to move bottom panel 23 vertically up to form the desired opening 20 near the top of the window assembly 10 (FIG. 1).

Referencing FIG. 11, it shows the opening 20 near the middle of the window assembly 10, referenced in FIG. 1. From the previous position of opening 20 as in FIG. 10 the change can be made by partially retracting zippers 24, allowing bottom panel 23 to be vertically lowered to establish the bottom of the desired opening 20. Then, by partially extending, zipping, both zippers 26 of the top panel 25 causing the top panel 25 to be lowered to the desired top of the opening 20. Thus, the top panel 25 forms the top of the opening 20 and the bottom panel 23 forms the desired bottom of opening 20. The opening 20 can be adjusted anywhere near the middle of window assembly 10 (FIG. 1) by zippers 24 and/or zippers 26. This method of adjusting both sets of zippers 24 and 26, the bottom panels 23 and top panel 25 can create a desired vertical opening 20 size and the vertical the height of opening 20 between a fully opened window and fully closed one.

In FIG. 12, it shows the opening 20 at the bottom of the window assembly 10, referenced in FIG. 1. From the previous position of opening 20 as in FIG. 11 the change can be made by totally retracting zippers 24, allowing bottom/inside panel 23 to fall to the bottom of the window assembly 10 (FIG. 1), then zippers 26 of top/outside panel 25 are partially extended (zipped) to the desired top edge of the formed opening 20 near the bottom of window assembly 10 (FIG. 1) and still having a formed awning within top panel 25.

Another embodiment FIG. 13 for this invention is a variable view window assembly 35 affixed within the wall 40 of a commonly used hub type framed hunting enclosure 30. This type of enclosure 30 requires an irregular window assembly 35 consisting of the top/outside panel 55 with zippers 56 along its angular side margins. The outside view of enclosure 30 with a window assembly 35 is shown with its bottom/inside panel 53 partially retracted forming the bottom edge of the defined window opening 50 and the top/outside panel 55, as fabricated within and part of the wall 40, being partially retracted by its zippers 56 and the constant-force springs, not seen, partially relaxed within the two pockets 57. The position of the bottom panels and the top panel 55/40 creates the opening 50 near the middle of the window assembly 35 depicted in FIG. 13. FIG. 14 illustrates the inside wall 40 of the enclosure 30 depicted in FIG. 13 with split views of the same window assembly 35 (FIG. 13). The left view, FIG. 14a depicts an opening 50 near the middle of the window assembly 35, referenced in FIG. 13. The bottom panel 53 is partially retracted (lowered) by unzipping zippers 54 and the top panel 55/40 (as part of the wall 40) is partially retracted (raised) by unzipping zippers 56 which allows the top panel 55/40 to roll upward and outward due to the relaxed constant-force springs 58 and 58a which are located inside affixed pockets 57 and 57a, thus forming the opening 50 near the middle of the window assembly 35 depicted in FIG. 13 and the awning outside of wall 40. Also, depicted in the right view FIG. 14b the window opening 50 is located at the bottom of the window assembly 35, referenced in FIG. 13. The bottom panel 53 is fully retracted (unzipped) by zippers 54 allowing it to fall down inside wall 40 by gravity and the top panel 55/40 is fully extended (zipped closed) by zippers 56 to form an opening 50 at the bottom of window assembly 35 (FIG. 13). In both FIGS. 14a and 14b the pockets 57a and the constant-force springs 58a are fabricated to length and with the right vertical location to properly raise top panel 55/40 vertically within the irregular shaped window assembly 35 depicted in FIG. 13.

The foregoing preferred embodiments of this invention have been presented for purposes of illustration and description.
