DETAILED DESCRIPTION OF THE INVENTION

[0033] With reference to FIG. 1, there is illustrated the attic-insulation cover device 10 of the present invention in combination with a standard attic-opening frame unit 14, known to the art for access to a building attic space 30 or the like.

Attic Opening Frame 14

[0034] Referring to FIGS. 1 and 4, a typical attic-opening frame 14 has an interior surface 15 and an exterior surface 16, and generally consists of a square or rectangular framework of boards, typically 2″×10″ boards, formed by parallel opposing frame boards 17, 18 attached to parallel opposing frame boards 20, 22, surrounding the attic opening 24 to form the framework.

[0035] The frame 14 is typically built into the framework (not illustrated) of the attic space 30 in a manner known to the art. The attic opening 24 is cut from the ceiling 25 and a framework 27 of typically mitered frame boards 27a, 27b, 27c and 27d frame the opening 24 both for aesthetics and to provide a support for the cover panel 26 with a lip 28.

Attic-Insulation Cover 10

[0036] Referring now to FIGS. 1 and 2, the attic-insulation device 10 of the present invention is defined by two separable units, an attic insulation flange 50 or border and an insulation jacket 52, which is removably secured to the flange 50 by a connection or closure device 56, such as a zipper, hook and loop fastener, or the like. For purposes of describing the present invention, the closure device 56 will illustrated as a standard zipper.

Material for Constructing Attic-Insulation Cover 10

[0037] The material used for constructing the attic-insulation device 10 is preferably a thick, rip stop or non-tearing flexible material, such as canvas, heavy or rubberized cotton or the like. The preferred material is fire proof or at least fire resistant. A preferred material for use in the construction of the attic-insulation cover 10 is a flexible two-sided foil faced foam insulation with ¼″ inch nominal thickness, such as that produced by Environmentally Safe Products, Inc. (New Oxford, Pa. 17350). When using the preferred wall material as described, the insulation capacity is increased by around nine Rs.

Attic Insulation Flange 50

[0038] The attic insulation flange 50 is designed to fit within the attic-opening frame 14 and provides a border for attic insulation 60, illustrated in FIGS. 5 and 9, to abut to it.

[0039] The attic insulation flange 50 is defined by elongated parallel side walls 68, 70 connected to parallel end walls 72, 74. The flange 50 is bordered by a first upper end 76, a second lower end 78, an exterior surface 80 and an interior surface 80 defining the flange opening 84. As illustrated in FIGS. 1-4, the first upper end 76 is defined by the closure device 56. The flange 50 is designed to fit within the interior surface 15 of the frame 14 in a generally snug fit relationship to minimize air leakage from the attic space 30, as illustrated in FIG. 1.

Attic Insulation Jacket 52

[0040] The insulation jacket 52 is a separate component of the attic-insulation cover 10, which can be removably secured to the attic insulation flange 50 by means of the closure device 56, i.e., a zipper. As illustrated in FIGS. 1-4, the insulation jacket 52 includes an attic insulation chamber 53 connected to a bridge section 54. The jacket 52 and bridge section 54 are separated by a separation panel 89, which includes an interior surface 92 and an exterior surface 94. The separation panel 89 connects to parallel sidewall panels 93, 95 at edges 75, 77. The bottom panel 89 further includes ends 103 and 105. The sidewall panel 93 includes an interior surface 100 and an exterior surface 102. The sidewall panel 95 includes an interior surface 104 and an exterior surface 106. The insulation chamber 53 is completed with a top panel 90 having an interior surface 108 and an exterior surface 110.

[0041] The top panel 90 connects to side panels 93, 95 at edges 96, 98 and includes ends 97, 99. The connected panels 89, 90, 93 and 95 form an interior chamber 112 with openings 114 and 116 at either end of the attic insulation jacket 52. The interior chamber 112 is designed to receive insulation 101 as illustrated in FIG. 3 and as will be described further on. Accordingly, the sidewalls 93, 95 are preferably between about 7 and 15 inches high such that the interior chamber 112 can accommodate the insulation 101.

[0042] The top panel 90 further includes at least one and preferably two flexible extension flaps 120, 122 on either end 97, 99 of the top panel 90. As illustrated in FIGS. 1 and 4, the extension flaps 120, 122 are designed to fold forming creases 124, 126 such that the ends 97, 99 of the extension flaps 120, 122 will come into communication with the ends 103, 105 of the separation panel 89.

[0043] As illustrated in FIGS. 3 and 4, a securement device 130 is provided for adhering the ends 97, 99 to ends 103, 105 respectively. As illustrated in the drawings, the securement device 130 is preferably releasable, such as a co-acting hook and loop, i.e., VELCRO connector. However, the securement device 130 can also be snaps, buttons, staples, zippers, needle and thread or any other type of device known for securing the ends together. If desired, the insulation chamber 53 can be permanently closed at one end, leaving the other end open to receive the insulation 101. For purposes of illustration, the securement device 130 is of the hook and loop or VELCRO variety, having a first securing piece 132 attached, by glue, stitching or other means, to ends 103, 105 of the bottom panel 89 of the insulation chamber 53. A second securing piece 134 is attached to the ends 97, 99 of the extension flaps 120, 122 on the interior surface 108 of the top panel 90. To close off the interior chamber 112 of the insulation chamber 53, the extension flaps 120, 122 are creased and bent at edges 124, 126 such that the ends 97, 99 of the extension flaps 120, 122 come into contact with the ends 103, 105 of the bottom panel 89 to allowed the securing pieces 132, 134 to releasably connect.

[0044] As discussed above, the attic insulation jacket 52 is further defined by a bridge section 54 connected at its upper end 55 to the separation panel 89 of the insulation chamber 53 forming a seam 58 therebetween. The bridge section 54 includes a lower end 57 and two sets of connected parallel walls 59a, 59b, 59c and 59d. The combination of the parallel walls 59a-59d and the exterior surface 94 of the separation panel 89 forms a cover panel pocket 61 for purposes of placement of the cover panel 26 when the insulation device 10 is opened for access into the attic space 30.

Insulation 101

[0045] Once the insulation chamber 53 is constructed, insulation 101 is preferably installed within the interior chamber 112 of the insulation chamber 53, as illustrated in FIG. 3. While there are a variety of forms of insulation 101 for placement within the interior surface 100, a preferred form is a standard “batt” of insulation 101 known to the art. The interior chamber 112, illustrated in FIG. 3, is preferably designed to accommodate a standard batt of insulation 101, having standard dimensions of approximately three feet wide and one foot high. The length of the batt of insulation 101 can be cut to accommodate the length of the insulation chamber 53. Typical batt of insulation 101 will have an R-38 insulation factor although the insulation chamber 53 can hold insulation having an R-49 factor or more.

[0046] The extension flaps 120, 122 of the top panel 90 are then secured as described above to retain the insulation 101 within the interior chamber 112 of the attic insulation jacket. While insulation 101 is not required to be placed within the interior of the insulation jacket, it is desired to do so in order to enhance the insulation ability of the pulldown ladder jacket 12.

Construction of the Attic-Insulation Cover 10

[0047] As described previously, the wall material is preferably made of 2-sided foil faced foam insulation with ¼″ inch nominal thickness. The preferred material is produced by Environmentally Safe Products, Inc. (New Oxford, Pa. 17350). Other fabric material, such as canvas, cotton and other preferably heavy grade materials can also be used for this invention. It is especially preferred that the material be flexible and foldable for ease of storage when not in use and ease of packing for shipment.

[0048] The closure device 56 is preferably a nylon coil zipper, typically a 5-gauge 1-inch zipper and made of 100% polyester, catalog #688, manufactured by Lenzip Manufacturing Corporation (Rolling Meadows, Ill.). Non-lock long pull #5 gauge sliders catalog #487 are attached to the zipper coil. Although zippers are the preferred closure device, it is within the scope to use other connectors, such as hook and loop (VELCRO) fasteners and the like.

[0049] The attic-insulation cover 10 is preferably constructed by a sewing machine using T-60 Edd core PCP black nylon thread T/II AA50199 (Eddington Thread Manufacturing, Bensalem, Pa.). The hook and loop fasteners are preferably 1-inch wide industrial strength VELCRO strips, model #624 (Velcro USA, Inc., Manchester, N.H.).

[0050] A preferred process for manufacturing the attic-insulation cover 10 of the present invention uses the following steps: [0051] Cut off a piece of 1-inch coil zipper, 12 feet long and attach two of the non-locking zipper sliders on the zipper; the noses of each slider must be facing each other once in place. [0052] Cut 1 piece of the 10-inch foil-faced foam insulation at thirteen feet. [0053] Get a sheet of 24″ by 55″ piece of foam insulation. [0054] Sew one-half of the piece of coil zipper around the perimeter of the sheeted piece of foam insulation. [0055] Take the 10″ piece of foil-faced foam insulation and sew the other half of the coil zipper around one side of that piece which forms the bottom part or the flange of the jacket. [0056] Take a 42″×68″ oversized piece of sheeted insulation, i.e., the top panel 90 and sew it to the 24″×55″ piece (the bottom panel 89) on the long sides only. Once sewn together, this creates the attic insulation jacket 52, which forms the interior chamber 112 to receive the insulation 101. [0057] As the top panel 90 is around 13″ longer than the bottom panel 89, this results in a 6½″ overlap on the ends 97, 99, the extension flaps 120, 122, to fold down and close off interior chamber 112 once the insulation 101 is inserted to prevent loss of the insulation 101. [0058] To create the securement device 130, a piece of approximately 6″ hook and loop (VELCRO) adhesive strip is placed on the interior surface 108 of the top panel 90 at both ends 97, 99. The mating pieces of hook and loop adhesive strips are then adhered to the interior surface 92 of the bottom panel 89 at ends 103, 105.

[0059] Once the pulldown ladder jacket 52 is fully constructed, it is now ready to be attached to the attic-opening frame 14 of the pulldown ladder unit 12, as illustrated in FIGS. 7-9. Alternatively and preferably, a batt of insulation 101 is installed within the interior chamber 112 of the insulation jacket 52, as illustrated in FIGS. 4A, 5 and 6.

[0060] The extension flaps 120, 122 on the top panel 90 of the insulation jacket 52 are then creased at lines 124, 126 and folded downwardly such that the first securing pieces 132 on the ends 97, 99 of the top panel 90 meet the second securing pieces 134 on the ends 103, 105 of the bottom panel 89, as illustrated in FIGS. 5-6.

Installation of the Attic-Insulation Cover 10 on the Attic Opening Frame 14

[0061] One distinct advantage of the attic-insulation cover 10 of the present invention is the ease of installation. The attic-insulation cover 10 itself is relatively light, flexible and typically weighs less than about 20 pounds even with the insulation 101 installed within the interior chamber 112 of the insulation chamber 53. In addition, the material making up the attic-insulation cover 10 is flexible thereby allowing the device 10 itself to be easily transported and manipulated during installation.

[0062] While the attic-insulation cover 10 as described above is preferably designed for installation on an attic opening frame 14 having a 3 foot opening, it is within the scope of the present invention to adjust the dimensions of the attic-insulation cover 10 to meet the specifications of attic openings 24 of any dimension.

[0063] Once the attic-insulation cover 10 has been prepared, it is now ready for installation as illustrated in FIG. 4. With reference to FIGS. 4 and 6, the attic-insulation cover 10 is positioned such that the flange 50 is fitted within the interior of the frame 14, as illustrated in FIG. 6. As an added advantage of the installation of the flange 50 in this manner, the flange 50 eliminates the need for a weather stripping frame because the flange 50 itself acts as a weather strip. As illustrated in FIG. 2, the flange 50 preferably includes an open, overlapping section at seam 107 to assist in the positioning of the flange 50 with respect to the frame 14.

[0064] Once the flange 50 has been installed, the flange can be secured to the frame 14 by securing devices known to the art, such as staples (illustrated in FIG. 1), nails (illustrated in FIG. 6) or glue. Once the flange 50 has been secured to the frame 14, a caulking material can be applied to the gap between the flange 50 and the frame 14 to prevent further loss of heat or cool air.

[0065] FIG. 6 is a bottom perspective view of the attic insulation device 10 of FIG. 1 illustrating the device 10 attached to the frame 14 of the ceiling 25. As illustrated, the flange 50, the bridge section 54 with the cover panel pocket 61 and the exterior surface 94 of the bottom panel 89 of the insulation chamber 53 are visible. The insulation jacket 12 is secured to the flange 50 by means of the closure device 56, i.e., a zipper extending around the perimeter of the insulation jacket 12.

[0066] As illustrated in FIGS. 1 and 6-9, the attic-insulation device 10 is ready to use either to insulate the attic opening 24 or to allow access to the attic space 30. To access the attic space 30, the cover panel 26 is elevated by an operator (not illustrated) from the lip 28 of the framework 27 on the ceiling 25 an temporarily held in place in cover panel pocket 61, as illustrated in FIG. 8. This action exposes the closure device 56, which is then separated. If a zipper is used, the zipper is separated by pulling the zipper pulls 56a thereby separating the insulation jacket 52 from the flange 50, as illustrated in FIG. 9, to lift the insulation jacket 52 from the flange 50 for access to the attic space 30. Reattaching the insulation jacket 52 to the flange 50 to close off the attic opening 24 is an easy procedure, which essentially reverses the steps described above with respect to gaining access to the attic space 30.

[0067] Reference is now made to FIGS. 10-12 for a second embodiment of the present invention directed to a knee wall jacket. As illustrated in FIGS. 10-12, an attic knee wall is typically a short vertical wall 200 that extends from the floor 202 probably to the roof rafters (not illustrated). Therefore, the knee wall opening 204 is effectively a crawl space opening for a user to access the attic. The knee wall opening 204 is cut out of the wall 200 and covered by a hinged knee wall door 206, typically having a handle 208 to latch the door. In order to provide enhanced insulation and loss of heat in the winter and cool air in the summer, the knee wall opening 204 can be provided with a knee wall insulation device 210, which is similar to the attic insulation device 10, described above. However, the knee wall insulation device 210 is vertically oriented. Like the attic insulation device 10, the knee wall insulation device 210 includes a door-insulation flange 212, which is similarly attached to square or rectangular framework 214 of the knee wall opening 204. The flange 212 has a first end 212a and a second end 212b where the second end 212b is defined a closure device 218. Unlike the attic insulation device 10 of the present invention, there is no need for a bridge section 54 as there is no need for a separate cover panel 26. In this manner, the knee wall insulation device 210 operates in a similar manner to the insulation device described and claimed in applicant's parent U.S. application Ser. No. 15/337,065, which is incorporated herein by reference in its entirety.

[0068] The knee-wall insulation device 210 comprises a bottom panel and a top panel, parallel sidewall panels and parallel ends thereby forming an interior chamber. While not disclosed in the drawings, they are identical to that described and disclosed with respect to the insulation device 10 described previously. At least one end of the device 210 can be open and adapted to be removably closed. The interior chamber is adapted to receive and retain insulation as described previously. The top panel further includes at least one extension flap on at least one of the top panel ends. The extension flap is adapted to communicate with one end of the bottom panel of the knee-wall door-insulation jacket. The extension flap and the interior surface of the bottom panel include a communicating securement device for releasably securing the extension flap to the bottom panel end. For purpose of this description, the closure device 218 is illustrated as a zipper with a zipper pull 220.

[0069] Reference is further made to FIGS. 13-14 for a third embodiment of the present invention directed to a full-sized door jacket 300, which will insulate a full-sized door 302. As illustrated in FIGS. 13 and 14, the door 302 and the accompanying door frame 304 provides a standard size door opening 306 sufficient to enable a typical human to walk through the opening 306 without the need to stoop. The door 302 can be for an attic entrance. However, the door 302 can also be used for any door entrance, such as a garage entrance. The door 302 typically has a handle 305 to latch the door 302.

[0070] In order to provide enhanced insulation and loss of heat in the winter and cool air in the summer, the door opening 306 can be provided with a door jacket or insulation device 300, which again is similar to the attic insulation device 10, described above. Like the knee wall door insulation device 210, the door jacket 300 is vertically oriented. The door jacket 300 further includes a flange 308, which is similarly attached to the rectangular framework 304 of the door opening 306. Similar to the knee wall insulation device 210, there is no need for a bridge section 54 as there is no need for a separate cover panel 26. In this manner, the door jacket 300 operates in a similar manner to the insulation device described and claimed in applicant's parent U.S. application Ser. No. 15/337,065, which is incorporated herein by reference in its entirety. The door jacket 300 includes a door insulation jacket 310, which is attached to the flange 308 by a closure device 312. For purpose of this description, the closure device is illustrated as a zipper with a zipper pull 314. Reference is made to the description of the insulation chamber 53 for a description of the door jacket 300. Like the insulation chamber 53, the door jacket also includes an insulation chamber 314, which can accept a batt of insulation.
