DETAILED DESCRIPTION OF THE INVENTION

(16) The following definitions and discussion of general principles are offered to provide context for the subsequent detailed description of preferred embodiments of the invention.

(17) As used herein, “smooth surfaces” or words of similar effect shall mean slippery, low friction surfaces. It is known that bed bugs and similar (typically arthropod) pests can walk across the smoothest of surfaces, including glass, when placed substantially horizontally. However, the steeper the slope or incline of a surface, the greater the difficulty bed bugs experience in climbing upwardly along the surface. Depending on the life stage of the bed bug and the smoothness of the surface, increasing the angle of incline will eventually make it impossible for the bed bugs to traverse the surface to its top. When disposed vertically or substantially vertically, bed bugs cannot traverse upwardly along smooth surfaces. Further, regardless of orientation, bed bugs and similar pests cannot cling to such surfaces. Therefore, they cannot harborage on them for prolonged periods of time and, as a result, cannot lay eggs on them that have a viable likelihood of survivability.

(18) As used herein, “barrier” or words of similar effect shall mean material through or over which a bed bug cannot pass. Since, as noted above, it is nearly impossible to chemically or thermally treat all harborages inside a box spring, mattress or bed frame, it is important to establish a physical barrier that bed bugs cannot penetrate or traverse whereby humans, pets and other objects are isolated from the bed on which they rest.

(19) As used herein, “outer surface” or words of similar effect shall mean a surface of the inventive device facing away from a potentially infested object, e.g., mattress and/or box spring, that is covered by the device. Conversely, an “inner surface” or words of similar effect shall mean a surface of the device facing toward the potentially infested object. The outer surface of the skirt of the subsequently described device should be substantially smooth. It is also preferable that the inner surface of the device also be smooth in order to reduce harborage and egg attachment and hinder bed bugs from moving over the interior of the device.

(20) As used herein, “top component”, “top material” or words of similar effect shall mean material that contacts the upper surface of a bed and upon which humans, pets, luggage, or other objects to be protected may rest. Such top component or top material is preferably fabricated from at least one layer of material that renders the cover impenetrable to the mouthparts of bed bugs.

(21) As used herein, “skirt” or words of similar effect shall mean material connected to and downwardly depending from the top material.

(22) As used herein, “fitted cover” or words of similar effect shall mean a flexible bed cover that is of a size and shape to closely conform to bed structure received therein.

(23) As used herein, material that may be “tucked” or words of similar effect shall mean material of sufficient suppleness or pliancy to be inserted between a mattress and underlying structure, including but not limited to bed structure such as a box spring, and maintained between the bottom surface of the mattress and the underlying structure by virtue of the weight of the mattress.

(24) With the foregoing in mind, referring to the drawings wherein like or similar references indicate like or similar elements throughout the several views, there is shown in FIG. 1 a bedding arrangement, identified generally by reference numeral 10, including a box spring 12, a mattress 14 and a fitted bed covering device 16 according to the present invention. Although the mattress and box spring are depicted as being of conventional rectangular shape, it will be understood that that such bedding, and the corresponding bed covering device of the instant invention adapted for covering same, may assume any peripheral shape.

(25) Bed covering device 16 is preferably fabricated from supple materials that enable compact folding of the device for convenient storage and transport. In addition, device 16 has an open bottom whereby it may be placed over bedding without having to completely lift the bedding in order to install and remove the device. Further, the device is fitted so as to closely accommodate and conform to the underlying bedding component(s) in order to provide substantially vertical surfaces that resist climbing by crawling pests such a bed bugs and present an aesthetically pleasing profile for conventional bed coverings that may be placed atop the device.

(26) Bed covering device includes a top component 18 comprising barrier material suitable for preventing passage of the needle-like mouthparts of bed bugs whereby bed bugs cannot penetrate the material and bite humans or animals resting on the bedding. The barrier material may comprise either a porous material including at least one layer having pores smaller than the needle-like mouthparts of bed bugs or an essentially non-porous material alone or in combination with an overlying porous material for contacting a user's skin. In either case, multiple layers of material may be joined by any suitable lamination, bonding or other suitable fastening techniques known in the art.

(27) Device 16 further includes a fitted, downwardly depending and continuous skirt 20 joined to the periphery of the top component 18. Skirt 20 has a slippery, i.e., low friction, exterior surface that hinders bed bugs and similar pests from climbing up the covered bedding and gaining access to humans, animals, or objects resting atop the bedding. Top component 18 and skirt 20 may be formed as a unitary construction or as separate pieces connected by mechanical or other fastening techniques. For example, the periphery of top component 18 may be joined to skirt 20 by a continuously sewn seam 22 and the ends of the skirt may be joined by a similar, sewn seam 24. If sewn together, however, it is preferable that, particularly with respect to the seam 24, the excess fabric required for producing the seams be directed toward the inner surface and not the outer substantially smooth surface of the skirt. In that way, contiguous edges of the skirt, if properly stitched, can prevent bed bugs from climbing upward along the outer surface of skirt 20. In the alternative, the ends of skirt 20 may be effectively joined by adhesive, thermal or other known bonding techniques in order to produce an essentially smooth seam that renders scaling of the skirt prohibitive to bed bugs and other such pests.

(28) Additionally, as will be discussed in greater detail herebelow, skirt 20 is preferably of a length “L” greater than the height of the sidewalls of mattress 14 in order to minimize the likelihood of bed bugs or similar pests from scaling conventional bed coverings that may be placed atop device 16.

(29) Turning to FIGS. 2-5, there is shown a first embodiment of a bed covering device according the present invention, such device identified generally by reference numeral 116. The skirt 120 of device 116 is adapted to cover the sidewalls of a mattress 114 and, at least in part, the sidewalls of a box spring 112. As seen in those figures, the length of skirt 120 is substantially greater than the height of the sidewalls of mattress 114. In particular, the length cf skirt 120 is preferably at least about twice and up to about three times the height of the sidewalls of the mattress 114. So constructed, a portion of the skirt material may be inserted or tucked between mattress 114 and box spring 112 to create a tuck 126 that is effectively maintained by the weight of the mattress, the tuck being of sufficient depth to function as means for retaining conventional bed covering(s) 128 (FIG. 5), such as a fitted fabric sheet, an unfitted fabric sheet, a blanket/comforter, or any combination thereof. Together, tuck 126 and the remaining downwardly depending portion 130 of skirt 120 effectively establish a continuous barrier preventing access of bed bugs and similar pests from the box spring 112 and mattress 114 to bed covering(s) 128. Barred access to the bed covering(s) 128, the pests cannot climb the bed covering(s) and infest the top surface of the bed.

(30) Referring to FIGS. 6 and 7, there is shown a further embodiment of the invention wherein the bed covering device is identified by reference numeral 216. As revealed in those figures, skirt 220 has a length L which is sufficient to cover both the sidewalls of mattress 214 and at least the upper regions of the sidewalls of box spring 212. While effective for preventing bed bugs or similar pests from scaling the skirt 220 if the skirt extends below the lower edge of conventional bed covering(s) that may be placed thereover, device 216 is not equipped with dedicated means for assuring that such bed coverings do not contact either the mattress 214 or the box spring 212.

(31) FIG. 8 illustrates another embodiment of a bed covering device according to the invention, identified generally by reference numeral 316. According to this embodiment, the length L of skirt 320 is sufficient to envelop both a mattress and a box spring, both of which are obscured by skirt 320. For context, FIG. 8 also shows a pedestal or other box spring support structure 332 beneath the box spring to convey how the skirt extends to the bottom of the box spring. Optionally the lower edge of skirt 320 may be provided with elastic, a draw string or similar means 332 for securing the skirt against the bottom of the box spring.

(32) FIG. 9 illustrates another embodiment of a bed covering device according to the invention, identified generally by reference numeral 416. Unlike prior embodiments, device 416 includes means 434 external of skirt 420 for effectively preventing contact of conventional bed covering(s) 428 with underlying bedding. As illustrated, such means are constructed as one or more bands or straps 434 sewn, adhered or otherwise fixedly secured to one or more of the foot and side regions of the outer surface of skirt 420. The bottom portions 436 of the conventional bed covering(s) are inserted in means 434 in order to suspend the bed covering(s) above the lower edge of skirt 420. It will be appreciated that such means are not necessary at the head region of the skirt since a user desirous of laying on the bedding needs to lift the bed covering(s) at the head of the bed in order to lie under the bed covering(s) after which the user's body maintains the bed covering(s) separate from the bed covering device, at least at the head region of the bed.

(33) Although shown as individual straps or bands, means 434 may be a continuous band spanning the bottom and side regions of skirt 420. And, in the alternative, means 434 may be constructed as closed-bottom pouches or pockets.

(34) FIG. 10 illustrates another embodiment of a bed covering device according to the invention, identified generally by reference numeral 516. Similar to FIG. 9, device 516 includes means 534 exterior of skirt 520 for suspending the lower edges of bed covering(s) 528 from contacting underlying bedding. According to FIG. 10, such means 534 comprise loops or rings affixed to the corners of the skirt located at the foot of the bed through which bunched bed covering material 536 is inserted.

(35) FIG. 11 illustrates another embodiment of a bed covering device according to the invention, identified generally by reference numeral 616. The construction shown in FIG. 11 departs from those illustrated in FIGS. 9 and 10 in that, rather than removable bed covering(s), such covering(s) 628 are attached to the bed covering device substantially at or near the periphery of the top component 618 along upper edge 636 via stitching, adhesives or other suitable means, thereby rendering the slippery outer surface of skirt 620 exposed. It is also contemplated that the bed covering(s) may be removably attached to the device 616 by hook and loop type fasteners, snaps, buttons or other suitable means. Preferably, bed covering(s) 628 are secured only about the lower or “foot” half of the top component 618 whereby a user may lift unattached upper or “head” portions of the bed covering(s), as shown by turned-down flap 638, to enable easy access between the top component 618 and the bed covering(s).

(36) FIG. 12 illustrates another embodiment of a bed covering device according to the invention, identified generally by reference numeral 716, over which lies bed covering(s) 728 and at least one pillow 740. According to this embodiment, device 716 further includes at least one pocket 742 for preventing pillow(s) 740 from contacting an adjacent headboard or wall, not shown, which may be infested with bed bugs or like pests. Pocket 740 has an opening 744 facing in a direction toward the foot region of the top component 718 and of sufficient size to receive pillow 740. Pocket(s) 742 may be fixedly or releasably attached to the top component 718 by any suitable attachment means described above. Additionally, pockets) 742 may be fabricated from any supple material, including, without limitation, any conventional bed covering fabrics, e.g., linen, or any of the above-described materials used to form the top component of the bed covering devices according to the invention. If, however, pocket(s) 742 are made of conventional bedding fabric then it is essential the that the rear of the pocket(s) be spaced sufficiently inwardly of the peripheral edge at the head region of the top component so that the pocket(s) cannot contact the adjacent headboard or wall and possibly create a pathway for bed bugs or similar pests.

(37) FIG. 13 reveals a further feature of the present invention which has utility independent of the bed covering devices described herein. However, it is contemplated such feature may be part of a system including any of the above-described bed covering devices which provides an additional measure of protection against encroachment by pests such as bed bugs.

(38) More particularly, FIG. 13 depicts an upright device for protecting the head region of a bed from encroachment by crawling pests such as bed bugs. Such device, identified generally by reference numeral 850, is a collapsible barrier including a continuous web 852 of supple material. Preferably, at least the surface of web 852 facing toward a headboard or wall, not illustrated, is slippery, i.e., has a low coefficient of friction, to inhibit scaling by bed bugs or the like. The material of web 852 may be the same as or the functional equivalent of the materials used for the skirts of the above-described bed covering devices.

(39) Device 850 further includes a collapsible frame 854 to which web 852 is attached by any suitable means. Frame 854 is made of foldable, resilient material, such as spring wire or the like, having an unstressed operative state in which the frame is unfolded. So constructed, in its operative state, the frame 854 draws the web 852 taut to establish a barrier for preventing encroachment by bed bugs and the like. Preferably, the lateral regions 856 of frame 854 are curved in the direction facing opposite an adjacent wall or headboard, i.e., toward pillow(s) 842, in order to further ensure that the pillow(s) do not contact the adjacent bedboard or wall. Significantly, device 850 is easily foldable into a compact, collapsed state whereby it may be readily packaged and transported with any of the above-described bed covering devices. To promote foldability of the frame 854 and reduce potential damage to the web 852 that might be caused by angular corners or edges, it preferred that at least a substantial portion, if not all, of the upper portions of frame 854 be curved. In addition, device 850 may be fixedly or releasably attached to the aforementioned bed covering devices by any suitable attachment means described above. It will be understood that device 850 may also be situated at the foot region of a bed, if desired.

(40) FIG. 14 reveals a further feature of the present invention which has utility independent of the bed covering devices described herein. However, it is contemplated such feature may be part of a system including any of the above-described bed covering devices which provides an additional measure of protection against encroachment by pests such as bed bugs.

(41) More particularly, FIG. 14 depicts an upright device for protecting the foot region of a bed from encroachment by crawling pests such as bed bugs. Such device, identified generally by reference numeral 950, is in many respects substantially similar in construction to device 850. That is, it is a collapsible barrier including a continuous web 952 of supple material. Preferably, at least the surface of web 952 facing toward a footboard 960, is slippery, i.e., has a low coefficient of friction, to inhibit scaling by bed bugs or the like. The material of web 952 may be the same as or the functional equivalent of the materials used for the skirts of the above-described bed covering devices.

(42) Device 950 further includes a collapsible frame 954 to which web 952 is attached by any suitable means. Frame 954 is made of foldable, resilient material, such as spring wire or the like, having an unstressed operative state in which the frame is unfolded. So constructed, in its operative state, the frame 954 draws the web 952 taut to establish a barrier for preventing encroachment by bed bugs and the like. Significantly, device 950 is easily foldable into a compact, collapsed state whereby it may be readily packaged and transported with any of the above-described bed covering devices and/or barrier device 850. Device 950 is preferably simply inserted between the footboard 960 and the mattress 914 and box spring 912. In the alternative, device 950 may be fixedly or releasably attached to the aforementioned bed covering devices by any suitable attachment means described above. It will be understood that device 850 may also be situated at the head region of a bed, if desired.

(43) Although the invention has been described in detail for the purpose of illustration, it is to be understood that such detail is solely for that purpose and that variations can be made therein by those skilled in the art without departing from the spirit and scope of the invention as claimed herein.
