The present invention relates to cover assemblies for mattresses. In particular, the present invention relates to cover assemblies for mattresses that make use of a first cover for enclosing the mattress and a second cover for covering at least a top panel of the first cover.
To protect a mattress and prevent it from becoming stained, torn, or otherwise damaged, mattresses are often surrounded by a mattress cover that completely covers the top, sides, and the bottom of the mattress. In most mattress covers, a zipper or other similar fastener is used to enclose the mattress cover on a single side or around a bottom portion of the mattress. Such mattress covers are often sufficient for protecting a mattress. However, in the event that the mattress cover does become stained, torn, or otherwise damaged, it may be exceedingly difficult to remove the mattress cover from the mattress and then replace it with a new or clean mattress cover. Additionally, mattress covers are almost always made from protective materials, such as plastics and coarse fabrics that prevent the underlying mattresses from becoming stained, torn, or otherwise damaged, but that can be irritating or uncomfortable to the skin of a user that comes into contact with such a mattress cover.
In this regard, mattress covers are often covered with a fitted sheet that completely covers the top of the mattress cover, the sides of the mattress cover, and a small portion of the bottom edge of the mattress cover (as a result of a lower edge of the fitted sheet being tucked under the mattress). Those fitted sheets typically provide a softer surface on which to rest the body of a user, and also typically provide a layer of material that can easily be removed and then cleaned or replaced should the fitted sheet become stained, torn or otherwise damaged. Nevertheless, it is often the case that fitted sheets slip off of the mattress cover and the underlying mattress, and can thus potentially fail to provide a sufficient additional layer. Moreover, such fitted sheets are often made from materials that ultimately fail to protect the underlying mattress cover as any staining or damage to the fitted sheet will also typically affect the mattress cover. Accordingly, a cover assembly that can be securely fastened to a mattress, or other support cushion, and provide a more sufficient layer of protection and functionality would be both highly desirable and beneficial.
The present invention includes cover assemblies for mattresses. In particular, the present invention includes cover assemblies for mattresses that make use of a first cover for enclosing a mattress and a second cover for covering at least a top panel of the first cover.
In one exemplary embodiment of the present invention, a cover assembly for a mattress is provided that includes a first cover having a top panel, a bottom panel, and a continuous side panel, with the panels collectively defining a cavity for enclosing the mattress. The continuous side panel of the first cover can be further characterized as including a head panel, a foot panel, and two opposing side panels. The cover assembly further includes a second cover having a top surface and a bottom surface, with the second cover defining a perimeter. A fastener connects the second cover to the first cover along the perimeter of the second cover.
The second cover of the cover assembly is generally positioned over the top panel of the first cover and is dimensionally-sized to cover at least the top panel. For example, in certain embodiments, the second cover is dimensionally-sized to cover the top panel and an upper half of each opposing side panel. In other embodiments, the second cover is dimensionally-sized to cover the top panel, an upper half of each opposing side panel, an upper edge of the foot panel, and an upper edge of the head panel. In even further embodiments, the second cover is dimensionally-sized to cover the top panel, an upper half of each opposing side panel, an upper half of the foot panel, and an upper half of the head panel.
Regardless of the particular size and arrangement of the second cover, the fastener connecting the second cover to the first cover is generally comprised of one or more zippers that extend around the perimeter of the second cover. In some embodiments, the zipper is a two-way separating zipper having two slider bodies extending around a single track to provide a fastener in which the zipper slider bodies and the zipper pulls can be located anywhere along the length of the track, such that the point of opening for the zipper can also be anywhere along the length of the track. In other embodiments, there are four separate zippers extending around the perimeter of the second cover, with one zipper extending along the head panel of the first cover, one zipper extending along the foot panel of the first cover, and one zipper extending along each side panel of the first cover. By incorporating such zippers into a cover assembly of the present invention, the second cover can thus easily be removed from the first cover by simply unzipping the one or more zippers and disconnecting the second cover from the first cover. The second cover can then be easily cleaned or replaced as desired.
To provide a second cover that can easily be cleaned upon being removed from the first cover, the second cover is also typically comprised of a textile that is sufficiently durable, but yet is machine-washable and easily cared for, such that the second cover can be removed from the first cover, cleaned, and then reconnected to the first cover. To further take advantage of the configuration of the second cover relative to the first cover of the cover assembly, however, one or more additional materials can also be incorporated into the first cover, the second cover, or both the first cover and the second cover of the cover assembly to provide an additional level of protection to the first cover and the underlying mattress enclosed by the first cover. For example, in some embodiments, the bottom surface of the second cover can include a water-impervious and vapor-permeable material that prevents liquids or other moisture from traveling from the second cover to the first cover and the underlying mattress, but that also allows any liquid or moisture in the first cover or underlying mattress to evaporate and travel through the second cover. As yet another example, in some embodiments, an exemplary cover assembly also preferably incorporates one or more flame-retardant materials into the first cover, the second cover, or both.
With further respect to the configuration of the cover assemblies of the present invention, in some embodiments, cover assemblies are provided that also include additional features designed to increase the comfort of a user lying on the cover assembly. For instance, in some embodiments, the second cover includes an amount of phase change material that is included in the second cover and is configured to provide cooling at the top surface of the second cover. Additionally, in some embodiments, the second cover includes an amount of a flexible foam positioned between the top surface and the bottom surface, such that the second cover can be used as an overlay to a mattress, or other support cushion, and provide an increased level of comfort. Moreover, in some embodiments, a charcoal sheet can be incorporated into the first cover, the second cover, or both the first cover and the second cover to eliminate or mitigate the presence of any odors or chemicals present in the cover assembly or the underlying mattress.
As an additional refinement to the cover assemblies of the present invention, in some embodiments, cover assemblies are provided in which the first cover, the second cover, or both the first cover and the second cover includes an indicia that is indicative of a characteristic of the mattress. By including such indicia on the first cover, the second cover, or both the first cover and the second cover, a user is able to visually identify a characteristic of a mattress, such as the firmness of the mattress or the type of the mattress. Further, in embodiments in which the cover assemblies of the present invention are used to cover a mattress comprised of a visco-elastic foam, the indicia can be used to not only identify the mattress as a visco-elastic foam-type of mattress, but can further be used to identify a characteristic of the visco-elastic foam, such as a density or hardness of the visco-elastic foam, or the number of layers of visco-elastic foam that are included in the mattress.
The indicia on the cover assemblies of the present invention can include patterns, colors, or combinations of patterns and colors, and can be positioned at a variety of different locations on the first and second cover. For instance, in some embodiments, the indicia is a pattern positioned on the top surface of the second cover. In other embodiments, the indicia comprises a plurality of geometric shapes embossed or debossed into or otherwise positioned on the end panel of the first cover, the side panels of the first cover, or both the end panel and side panels of the first cover.
In some embodiments, the indicia is a dot that is positioned on the top surface of the second cover and that has a color. In such embodiments, the end panel of the first cover has a color substantially identical to the color of the dot, such that both the second cover and the first cover include substantially the same indicia indicative of a characteristic of the mattress. In some embodiments, the indicia can be used as part of an overall bed assembly in which each of the components of the bed assembly or a select group of components include the indicia, such that the bed assembly not only includes the indicia on the cover assembly to indicate a characteristic of the mattress, but the additional components of the bed assembly (e.g., the foundation and the pillows) can also include the same indicia and indicate the characteristic of the mattress. In this regard, in certain embodiments, the cover and bed assemblies of the present invention can be used as an overall system in which multiple components of the bed assembly are marked with an indicia to allow for visual identification of a characteristic of a mattress.
With further respect to the cover assemblies of the present invention, an exemplary cover assembly can also be used as part of a method for marking a mattress to allow for visual identification of a characteristic of a mattress. In some implementations, a method for marking a mattress to allow for visual identification of a characteristic of the mattress includes first providing a mattress cover assembly having a first cover for enclosing a mattress and a second cover positioned over and dimensionally-sized to cover at least the top panel of the first cover. The top surface of the second cover is then marked with a first indicia that is indicative of a first characteristic of the mattress and that allows a user to visually identify a characteristic of the mattress by simply observing the mattress and associating the indicia with the characteristic (e.g., the firmness or type of the mattress). In some implementations, a second indicia can also be marked on the foot panel of the first cover, the two opposing side panels, or both the foot panel and the two opposing side panels, where the second indicia is indicative of either the first characteristic of the mattress or is indicative of a second characteristic of the mattress. For instance, in some implementations, both the first indicia and the second indicia are substantially the same color and are used to indicate that the mattress has a particular firmness. Alternatively, in other implementations, the first indicia is a pattern placed on the first cover and is used to indicate that the mattress is a visco-elastic foam mattress, while the second indicia is comprised of multiple rows of geometric shapes positioned on the end panel of the first cover and is used to indicate the number or types of layers of visco-elastic foam included in that particular visco-elastic foam mattress.
As an even further addition to the cover and bed assemblies described herein, in some embodiments, an exemplary bed assembly is provided that includes an alignment system for aligning a mattress assembly (e.g., a mattress assembly incorporating a cover assembly of the present invention) on a foundation. The exemplary bed assembly includes a foundation and a mattress having a first surface, a second surface opposite the first surface, and opposing sides. A first alignment member is attached to the head portion of the second surface of the mattress, while a second alignment member is attached to the foot portion of the second surface of the mattress.
Both the first alignment member and the second alignment member of the alignment system include two curved ends and an elongated center segment having a length sufficient to span a width of the mattress. In this regard, when the first and second alignment members are placed on the second surface of the mattress, the curved ends of the alignment members extend from the second surface of the mattress and around a particular side of the mattress. Four brackets are then used to secure the alignment members to the foundation, with the first bracket engaging the first of the two curved ends of the first alignment member, the second bracket engaging the second of the two curved ends of the first alignment member, the third bracket engaging the first of the two curved ends of the second alignment member, and the fourth bracket engaging the second of the two curved ends of the second alignment member.
To secure the alignment members to the brackets and, consequently, the mattress to the foundation of the bed assembly, the elongated center segment of each alignment member defines a first opening adjacent to the first of the two curved ends and a second opening adjacent to the second of the two curved ends. Both the first and second opening are generally in the form of an elongated channel that extends in a direction perpendicular to the longitudinal axis of the alignment member. In this regard, the first bracket and the second bracket each include a protuberance in the shape of a ridge that is configured and positioned such that, upon each bracket engaging a particular curved end of the alignment member, the ridge extends into a particular channel on the elongated center segment and secures each bracket to the alignment member to thereby align the mattress on the foundation.
Further features and advantages of the present invention will become evident to those of ordinary skill in the art after a study of the description, figures, and non-limiting examples in this document.
The present invention includes cover assemblies for mattresses. In particular, the present invention includes cover assemblies that include a first cover for enclosing a mattress and a second cover for covering at least a top panel of the first cover.

The cover assembly 10 further includes a second cover 40 having a top surface 42 and a bottom surface 44, with the second cover 40 also defining a perimeter 46. The second cover 40 of the cover assembly 10 is generally positioned over the top panel 22 of the first cover 20 and is dimensionally-sized to cover at least the top panel 22 of the first cover 20, the area of which is indicated by the hatching that is shown in

Further, by making use of a two-way separating zipper 50, the slider bodies 52a, 52b and zipper pulls 53a, 53b can be positioned on the two-way separating zipper 50, such that the slider bodies 52a. 52b and zipper pulls 53a, 53b can be hidden from sight when not in use or can be positioned along the perimeter 46 of the second cover 40 where the risk of the slider bodies 52a, 52b and zipper pulls 53a, 53b causing damage to the cover assembly 10, or any underlying mattress, is minimized. For example, the slider bodies 52a, 52b could be positioned adjacent to a panel of reinforcing fabric 54 on the perimeter 46 of the second cover 40, as shown best in FIG. 4. The panel of reinforcing fabric 54 helps to protect the second cover 40 when a user grabs one or both of the zipper pulls 53a, 53b and begins to move the slider bodies 52a, 52b along the track of the zipper 50, but yet also helps to identify the location of the slider bodies 52a, 52b and zipper pulls 53a, 53b.

In addition to increasing the area covered by the second cover 140 of the cover assembly 110, to further take advantage of the configuration of the second cover 140 relative to the first cover 120 and to provide an increased level of protection to the first cover 120 as well as any underlying mattress enclosed by the first cover 120, the bottom surface 144 of the second cover 140 also includes a water-impervious and vapor-permeable material 166. The water-impervious and vapor-permeable material 166 included in the bottom surface 144 of the second cover 140 can include materials such as expanded polytetrafluoroethylene (ePTFE, e.g., Gore-Tex®, W. L. Gore & Associates, Inc., Newark, Del.). In this regard, the water-impervious and vapor-permeable material 166 included in the bottom surface 144 of the second cover 140 thus prevent liquids from traveling through the top surface 142 and the bottom surface 144 of the second cover 140 into the first cover 120 and any underlying mattress, but yet allows vapors or moisture in the first cover 120 or in any underlying mattress to evaporate and travel though the second cover 140.
To provide a cover assembly 110 that is sufficiently “breathable” and allows air, heat, and moisture to travel through the cover assembly 110, but yet is also is sufficiently soft and durable, such that it can be easily cleaned and used to help prevent damage to the first cover 120 or an underlying mattress, the first cover 120, the second cover 140, or both are typically comprised of a textile. For example, in the embodiment shown in
In addition to using a textile to provide a level of protection to an underlying mattress, the exemplary cover assembly 110 also typically incorporates one or more flame-retardant materials into the first cover 120 and the second cover 140. By incorporating a flame-retardant material (e.g., a fire sock) into the first cover 120, the cover assembly 110 thus provides a flame-retardant barrier that completely surrounds an underlying mattress, such as a visco-elastic foam mattress as described herein below. Moreover, by incorporating a flame-retardant material into the second cover 140, the second cover 140 helps to prevent any flames or heated materials contacting the second cover 140 from damaging the underlying first cover 120.
With further respect to the configurations and materials used in the cover assembly 110, the first cover 120 of the cover assembly 110 also includes additional features to increase the comfort of a user lying on the cover assembly 110 (i.e., when the cover assembly 110 is used to on a mattress). More specifically, in the cover assembly 110, a flexible foam layer 164 is positioned between the top surface 142 and bottom surface 144 of the second cover 140, and thus acts an overlay that can be placed on top of a mattress along with the second cover 140 and used to provide an additional amount of comfort to a user. In the exemplary embodiment shown in
As an even further addition to the cover assembly 110 that increases the comfort of a user lying on the cover assembly 110, the first cover 120 of the cover assembly 110 further includes a charcoal sheet 168. As shown best in
Referring now to
The phase change material 269 that is incorporated into the top surface 242 of the second cover 240 is typically comprised of microspheres that include substances having a high heat of fusion and that store or release heat as the substances oscillate between solid and liquid form (i.e., phase change materials). As the phase change material 269 included in the top surface 242 of the second cover 240 changes from solid to liquid form (i.e., melts) as the result of heat generated by a user lying on the cover assembly 210, the phase change material 269 thus continually absorbs heat and provides a cooling effect to the user until all of the phase change material 269 has been transformed from a solid to a liquid form. In the top surface 242 of the second cover 240, the phase change material 269 is incorporated into the top surface 242 by infusing and coating the top surface 242 of the second cover with the microspheres of phase change material 269. However, it is, of course, contemplated that the phase change material 269 need not be infused into and/or used to coat only the top surface 242 of the second cover 240, but could also be infused into and/or used to coat the bottom surface 244 of the second cover 240, or the top panel 222 of the first cover 220 to provide a sufficient amount of cooling to the body of a user lying on the cover assembly 210.

As an additional refinement to the cover assemblies of the present invention, the cover assemblies can also include an indicia on either the first cover, the second cover, or both the first cover and the second cover that is indicative of and allows a user to visually identify a characteristic of the particular mattress covered by the cover assembly. Such indicia can include patterns, colors, or combinations of patterns and colors, and can be positioned at a variety of different locations on the first and second cover. For example, the cover assembly 10 shown in
Regardless of the type or location of the indicia, as noted, the indicia is preferably used to indicate a characteristic of the particular mattress that is covered by the cover assembly of the present invention. Such characteristics include, but are not limited to, the firmness of a particular mattress or the type of mattress that is covered by the cover assembly. For example, and referring now specifically to

With respect to the flexible foams used in the mattresses and flexible foam layers that are covered by the cover assemblies of the present invention, as noted above, the mattresses and flexible foam layers are generally comprised of a flexible foam that has a low resilience as well as a sufficient density and hardness, which allows pressure to be absorbed uniformly and distributed evenly across the various mattresses and flexible foam layers. Such flexible foams include, but are not limited to: latex foam; reticulated or non-reticulated visco-elastic foam (sometimes referred to as memory foam or low-resilience foam), reticulated or non-reticulated non-visco-elastic foam; high-resilience polyurethane foam; expanded polymer foams (e.g., expanded ethylene vinyl acetate, polypropylene, polystyrene, or polyethylene); and the like.
With respect to the hardness of the visco-elastic foams used in certain of the mattresses and flexible foam layers, suitable visco-elastic foams typically have a hardness of at least about 10 N to no greater than about 80 N, as measured by exerting pressure from a plate against a sample of the material to a compression of at least 40% of an original thickness of the material at approximately room temperature (i.e., 21° C. to 23° C.), where the 40% compression is held for a set period of time as established by the International Organization of Standardization (ISO) 2439 hardness measuring standard. In some embodiments, the visco-elastic foam can have a hardness of about 10 N, about 20 N, about 30 N, about 40 N, about 50 N, about 60 N, about 70 N, or about 80 N to provide a desired degree of comfort and body-conforming qualities.
With respect to the density of the visco-elastic foams used in certain of the mattresses and flexible foam layers suitable visco-elastic foams have a density that also assists in providing a desired degree of comfort and body-conforming qualities, as well as an increased degree of material durability. In some embodiments, the density of the visco-elastic foam used in the mattresses and flexible foam layers is no less than about 30 kg/m3 to no greater than about 150 kg/m3 In some embodiments, the density of the visco-elastic foam that is used is about 30 kg/m3, about 40 kg/m3, about 50 kg/m3, about 60 kg/m3, about 70 kg/m3, about 80 kg/m3, about 90 kg/m3, about 100 kg/m3, about 110 kg/m3, about 120 kg/m3, about 130 kg/m3, about 140 kg/m3, or about 150 kg/m3. Of course, the selection of a visco-elastic foam having a particular density will affect other characteristics of the foam, including its hardness, the manner in which the foam responds to pressure, and the overall feel of the foam, but it should be appreciated that a visco-elastic foam having a desired density and hardness can readily be selected for a particular application or assembly as desired.
Additionally, it should be appreciated that the visco-elastic foam used in the mattresses and foam layers described for use with the cover assemblies of the present invention need not be comprised of a single piece of visco-elastic foam, but can be comprised of multiple layers of visco-elastic foam with the layers having different densities and hardnesses. For example, in some embodiments, a visco-elastic foam mattress can be utilized that includes a lower supporting layer of visco-elastic foam with a density of about 80 kg/m3 and a hardness of about 13 N, and an upper comfort layer of visco-elastic foam with a density of about 35 kg/and a hardness of about 10 N.

In a similar fashion, and referring now to
With respect to the indicia included on an exemplary cover, it is understood that while the exemplary cover assemblies 410, 510, 610 make use of specific patterns and multiple rows of geometric shapes as indicia indicative of, respectively, a first characteristic and second characteristic of a mattress, numerous other patterns, colors, and the like can be incorporated into an exemplary cover assembly and designated to indicate a particular characteristic of a mattress. It is further understood that while the indicia 482, 582, 682 on the cover assemblies 410, 510, 610 described above have been used to indicate a number of layers of visco-elastic foam or varying hardnesses or densities of layers of visco-elastic foam, such indicia can also be used to indicate any number of other characteristics of a mattress without departing from the spirit and scope of the subject matter described herein.
By placing indicia on the cover assemblies of the present invention, each of the cover assemblies described herein can also be used as part of a method for marking a mattress to allow for visual identification of a characteristic of a mattress. In some implementations, a method for marking a mattress to allow for visual identification of a characteristic of the mattress includes first providing a mattress cover assembly having a first cover for enclosing a mattress and a second cover positioned over and dimensionally-sized to cover at least the top panel of the first cover. The top surface of the second cover is then marked with a first indicia that is indicative of a first characteristic of the mattress, such that a user can then visually identify a characteristic of the mattress by simply observing the mattress and associating the indicia with the characteristic (e.g. the firmness or type of the mattress). In some implementations, a second indicia can then also be marked on the foot panel of the first cover, the two opposing side panels, or both the foot panel and the two opposing side panels, where the second indicia is indicative of either the first characteristic of the mattress or is indicative of a second characteristic of the mattress, as described above.
As an even further refinement to the cover and bed assemblies described herein, and referring now to
The first alignment member 730a includes a first curved end 732a and a second curved end 733a that, although not fully shown in HG. 21, is substantially a mirror image of the first curved end 732a. The second alignment member 730b also includes a first curved end 732b and a second curved end 733b that are mirror images of one another. Both the first alignment member 730a and the second alignment member 730b also include elongated center segments 734a, 734b having a length that allows each of the alignment members 730a, 730b to span the width of the mattress 714. In this regard, when the first alignment member 730a and the second alignment member 730b are placed on the second surface 716 of the mattress 714, the first curved ends 732a, 732b of the alignment members 730a, 730b extend from the second surface 716 of the mattress 714 around one side 718 of the mattress 714, while the second curved ends 733a, 733b extend from the second surface 716 of the mattress 714 around the other side 717 of the mattress 714.
To complete the alignment system and secure the mattress 714 and the alignment members 730a, 730b to the foundation 712, the alignment system further includes four brackets 750a, 750b, 751a, 751b that are each configured to engage the curved ends 732a, 732b, 733a. 733b of the alignment members 730a, 730b. The four brackets 750a, 750b, 751a, 751b are also made of a rigid plastic material or other material having a sufficient strength, with the first bracket 750a engaging the first curved end 732a of the first alignment member 730a, the second bracket 751a engaging the second curved end 733a of the first alignment member 730a, the third bracket 750b engaging the first curved end 732b of the second alignment member 730b, and the fourth bracket 751b engaging the second curved end 733b of the second alignment member 730b.
To secure the alignment members 730a, 730b to the brackets 750a, 750b, 751a, 751b and, consequently, the mattress 714 to the foundation 712 of the bed assembly 710, the elongated center segment 734a of the alignment member 730a defines a first opening in the form of a proximal elongated channel 736a and a distal elongated channel 738a that are spaced at a predetermined distance and parallel to one another adjacent to the first curved end 732a of the alignment member 730a, and a second opening in the form of a proximal elongated channel 737a and distal elongated channel 739a that are spaced at a predetermined distance and parallel to one another adjacent to the second curved end 733a of the alignment member 730a. Likewise, the elongated center segment 734b of the alignment member 730b defines a first opening in the form of a proximal elongated channel 736b and a distal elongated channel 738b that are spaced at a predetermined distance and parallel to one another adjacent to the first curved end 732b of the alignment member 730b, and a second opening in the form of a proximal elongated channel 737b and distal elongated channel 739b that are spaced at a predetermined distance and parallel to one another adjacent to the second curved end 733b of the alignment member 730b. Each of the elongated channels 736a. 738a, 737a, 739a, 736b, 738b, 737b, 739b further extend in a direction perpendicular to the longitudinal axis of each of the alignment members 734a, 734b. In this regard, the four brackets 750a, 750b, 751a, 751b each include a protuberance in the shape of a ridge 754a, 755a, 754b, 755b configured and positioned on each of the four brackets 750a, 750b, 751a, 751b such that, upon each bracket 750a, 750b, 751a, 751b engaging a corresponding curved end 732a, 733a, 732b, 733b of the alignment members 730a, 730b, each ridge 754a. 755a, 754b, 755b extends into a corresponding channel 736a, 738a, 737a, 739a, 736b, 738b, 737b, 739b to secure the brackets 750a, 750b, 751a, 751b to the alignment members 730a, 730b. Of course, to the extent it may be desired, protuberances having different shapes that correspond to differently-shaped openings can also be used in an exemplary alignment system of the present invention without departing from the spirit and scope of the subject matter described herein.
