Description

(Related application)
This application claims priority based on a US provisional application (provisional application number 62 / 029,871) filed July 28, 2014. The disclosure of this provisional application is incorporated herein by reference in its entirety.

  The present invention relates to a mattress assembly including a mattress overlay and a plurality of covers. Specifically, the present invention relates to a mattress assembly that utilizes a first cover for wrapping the mattress and a second cover for covering the mattress overlay and at least the upper panel of the first cover.

  In order to protect the mattress and prevent the mattress from being soiled, torn or otherwise damaged, the mattress is often covered with a mattress cover that completely covers the top, sides and bottom. Many mattress covers are closed on one side of the mattress or surrounding the bottom using fasteners such as zippers. Such a mattress cover is usually sufficient to protect the mattress. However, if the mattress cover becomes dirty, torn or otherwise damaged, it may be difficult to remove the mattress cover from the mattress and replace it with a new (or clean) one. In addition, the mattress cover is most often made from a protective material such as plastic or a rough cloth to prevent the underlying mattress from becoming dirty, tearing and other damage. However, such a protective material may irritate the user's skin in contact with the mattress cover or give a sense of discomfort.

  In this respect, the mattress cover is often covered by a box sheet that completely covers the top, sides and a small portion of the lower edge (the lower edge of the box sheet is hidden under the mattress). As a result). Box sheets typically provide a soft surface on which the user's body lies, and also provide a layer of material that can be easily removed and cleaned or replaced when the box sheets become soiled, torn, or otherwise damaged. However, box sheets often disengage from the mattress cover and the underlying mattress (especially when using a mattress overlay), and may not provide sufficient additional layers. Further, box sheets are often made from materials that cannot protect the underlying mattress cover or mattress overlay. This is because box sheet soiling or damage can adversely affect the mattress cover, the mattress overlay, or both. Accordingly, it is preferred to use a mattress assembly that can be used with a mattress overlay, can be securely secured to a mattress (or other support cushion), and can provide a layer with better protection and functionality.

  The present invention includes a mattress assembly that includes a mattress overlay and a plurality of covers. Specifically, the present invention includes a mattress assembly that utilizes a first cover for wrapping the mattress and a second cover for covering the mattress overlay and at least the upper panel of the first cover.

  In an exemplary embodiment of the invention, a mattress assembly is provided that includes a mattress and a first cover having an upper panel, a lower panel, and a continuous (unbroken) side panel. The continuous side panel of the first cover includes a head panel, a foot panel, and two opposing side panels, and a cavity that wraps the mattress as a whole together with the upper panel and the lower panel. It may be characterized as defining. The first cover is further provided around a brand tag extending vertically along a part of the foot panel and an outer edge of the lower panel, and fixes the first cover around the mattress. And a zipper used for the construction.

  The mattress assembly further includes a mattress overlay disposed on the upper panel of the first cover. The mattress assembly further includes a second cover. The second cover has a top surface and a bottom surface and defines an outer peripheral portion. The second cover of the mattress assembly is generally disposed on (or above) the mattress overlay and the upper panel of the first cover, and covers the mattress overlay and at least the upper panel of the first cover. Have For example, in some embodiments, the second cover includes the mattress overlay, the upper panel of the first cover, the upper half of each of the two opposing side panels, the upper edge of the foot panel, And a size covering the upper edge of the head panel. By providing the second cover in an exemplary mattress assembly, the second cover may be exposed to excessive wear and increase the risk of soiling and damage, and the mattress overlay on the underside. The first cover parts (and thus the mattress parts under the first cover) are both covered and protected. Further, by providing the mattress assembly with the second cover, the upper half of the two opposing side panels has a more round shape when the second cover is attached to the first cover. Take.

  With respect to the mattress and mattress overlay included in the mattress assembly of the present invention, various types of mattresses and mattress overlays may be used in accordance with the present invention. The mattress and the mattress overlay may include, but are not limited to, a flexible foam, may have a plurality of inner springs, and may include one or more (e.g., provided within a rigid foam shell). You may have an air bladder (air bag) and may have these combination. However, regardless of the type of mattress or mattress overlay included in the exemplary mattress assembly of the present invention, the exemplary mattress assembly further includes the second cover along the outer periphery of the second cover. A fastener connected to one cover, such as a two-way separating zipper (two-way separating zipper) is provided. By providing the mattress assembly with the bidirectional separating zipper, the second cover can be easily removed from the first cover by simply moving the zipper pull and the slider body in the opposite direction to open the zipper (for example, the second cover). Not only can the cover be cleaned or replaced), but also the second cover can be easily reattached to the first cover.

  In some embodiments, the second cover configuration provides additional advantages and increases the level of protection of the mattress overlay, the first cover, and any lower mattress wrapped in the first cover. In order to make it possible, the bottom surface of the second cover may include a material having impermeableness and vapor permeability. The water impermeable / vapor permeable material prevents liquid from flowing through the top and bottom surfaces of the second cover to the mattress overlay, the first cover and the lower mattress, while Allow vapor or moisture to evaporate and move through the second cover in the cover or lower mattress. In this regard, it is sufficiently breathable and allows air, heat and moisture to pass through the mattress assembly while being soft and durable enough to be easily cleaned and to any part of the mattress assembly. In order to provide a first cover and a second cover that are used to help prevent damage, the first cover, the second cover or both are typically constructed from a fabric. For example, in some embodiments, the second cover is made of cotton. Accordingly, the second cover can obtain sufficient durability to protect the mattress overlay and the first cover, and can be machine-washed and easily maintained, whereby the second cover is attached to the first cover. Can be removed, cleaned and reattached to the first cover. In order to protect the lower mattress, in addition to the use of cloth, the first cover and the second cover typically incorporate one or more flame retardant materials into the first cover and the second cover, Provide a flame retardant barrier that sufficiently surrounds the side mattress.

  As a further improvement to the mattress assembly of the present invention, in some embodiments, an exemplary mattress assembly has a brand tag attached to the foot panel of the first cover. An exemplary mattress assembly may have indicia on either the first cover, the second cover, or both. The indicia indicate the characteristics of the mattress and / or mattress overlay included in the mattress assembly and allow the user to see and identify the characteristics. The indicia may include a pattern, a color, or a combination of a pattern and a color, and may be disposed at various positions on the first cover and the second cover. However, it is preferable to display the characteristics of the mattress and / or mattress overlay included in the mattress assembly of the present invention using the mark regardless of the type and position of the mark. The characteristic is, for example, but not limited to, the hardness or type of mattress or mattress overlay included in the mattress assembly. Further, in some embodiments, a plurality of indicia indicating a plurality of characteristics for the mattress or the overlay may be included.

  By placing a mark on the cover of the present invention, each cover described herein marks the mattress assembly to allow visual identification of the characteristics of the mattress and / or mattress overlay. It can also be used as part of the method. In one example, a method for marking the mattress assembly to allow visual identification of the characteristics of the mattress and / or mattress overlay includes first a first cover for wrapping the mattress, a mattress overlay, and Providing a mattress assembly with a second cover disposed on (or above) and covering at least the upper panel of the first cover. Next, the top surface of the second cover is marked with a first mark indicating a first characteristic of the mattress and / or the mattress overlay. This allows the user to simply look at the mattress and combine the indicia and properties (eg, the hardness and type of the mattress and / or the mattress overlay) to characterize the mattress and / or the mattress overlay. Can be identified. In one example, the foot panel of the first cover, the two opposing side panels, or both the two opposing side panels may be marked with a second mark. Here, the second mark indicates either the first characteristic or the second characteristic of the mattress and / or the mattress overlay.

These applications are incorporated herein by reference in their entirety.

  With respect to the mattress and mattress overlay included in the mattress assembly of the present invention, various types of mattresses and mattress overlays may be used in accordance with the present invention, and these mattresses and mattress overlays are exemplary described herein. May be covered with a mattress cover. The mattress and mattress overlay may include, but are not limited to, a flexible foam, may have a plurality of inner springs, and may include one or more air bladders (eg, provided in a rigid foam shell). You may have, You may have these combinations. For example, in the exemplary embodiment shown in FIGS. 1-9, the overlay is comprised of viscoelastic foam and the mattress (not shown) covered with the first cover 20 is an inner spring mattress.

  In relation to the flexible foam used for the mattress and the mattress overlay of the present invention, the mattress and the overlay are generally composed of a flexible foam that has a low restoring force and sufficient density and hardness as long as the flexible foam is used. This allows the pressure to be uniformly absorbed and evenly distributed across the various mattresses and overlays. Examples of flexible foam include, but are not limited to, latex foam, reticulated or non-reticulated viscoelastic foam (sometimes also referred to as memory foam or low resilience foam), reticulated or non-reticulated non-viscoelastic foam Polyurethane foam, foam polymer foam (eg, foamed ethylene vinyl acetate, foamed polypropylene, foamed polystyrene or foamed polyethylene).

  With respect to the hardness of the viscoelastic foam used in certain mattresses and flexible foam layers, the hardness of a suitable viscoelastic foam piece is usually from about 10N to about 80N. This hardness measurement method is defined by the hardness measurement standard of the International Organization for Standardization (ISO) 2439. At about room temperature (that is, 21 ° C. to 23 ° C.), pressure is applied to the material sample from the plate, The material thickness is measured by compressing at least about 40% of the material thickness and holding 40% compression for a predetermined time. In certain embodiments, the hardness of the viscoelastic foam may be about 10N, about 20N, about 30N, about 40N, about 50N, about 60N, about 70N or about 80N that provides the desired comfort and body fit. .

With respect to the density of viscoelastic foams used in certain mattresses and flexible foam layers, suitable viscoelastic foams will help to provide the desired comfort and body fit, and further increase the density to help improve material durability. Have. In some embodiments, the density of the viscoelastic foam used in the mattress and overlay is between about 30 kg / m ^{3 and} about 150 kg / m ³ . In certain embodiments, the density of the viscoelastic foam used is about 30 kg / m ³ , about 40 kg / m ³ , about 50 kg / m ³ , about 60 kg / m ³ , about 70 kg / m ³ , about 80 kg / m ³ , about They are 90 kg / m ³ , about 100 kg / m ³ , about 110 kg / m ³ , about 120 kg / m ³ , about 130 kg / m ³ , about 140 kg / m ³ , and about 150 kg / m ³ . Of course, the density of the viscoelastic foam selected will affect other properties of the foam (hardness, foam pressure responsiveness, overall foam feel, etc.), but will depend on the specific application or desired support. It should be understood that a viscoelastic foam having the desired density and hardness can be selected for the cushion.

Furthermore, the viscoelastic foam utilized in the mattress and overlay used with the mattress assembly of the present invention need not be composed of a single piece of viscoelastic foam, but a plurality of viscoelastic foam layers having various densities and hardnesses. It should be understood that it may consist of: For example, in one embodiment, a lower support layer of a viscoelastic foam having a density of about 80 kg / m ³ and a hardness of about 13 N, and a viscoelastic foam having a density of about 35 kg / m ³ and a hardness of about 10 N A viscoelastic foam mattress having an upper comfort layer (comfort layer) may be used.

  With reference to FIGS. 1-6, regardless of the type of mattress or mattress overlay included in the exemplary mattress assembly of the present invention, the mattress assembly 10 further comprises a bi-directional separating zipper 50 as a fastener. . The bidirectional separating zipper 50 connects the second cover 40 to the first cover 20 along the outer peripheral portion 46 of the second cover 40. As best shown in FIGS. 4 and 5, the bidirectional separating zipper 50 has two slider main bodies 52a and 52b, and each slider main body is connected to zipper pulls 53a and 53b. ing. Preferably, the zipper pulls 53a, 53b are larger than other zipper pulls used in conventional mattress covers. Thereby, the slider main bodies 52 a and 52 b can be easily moved along the outer peripheral portion 46 of the second cover 40. The slider bodies 52a and 52b are connected to the rails of the bidirectional separating zipper 50, respectively. Thereby, the slider main bodies 52a and 52b can slide around the rails of the zipper 50, and the first cover 20 can be moved at a desired position along the length of the bidirectional separating zipper 50 using the slider main bodies 52a and 52b. The second cover 40 can be separated from. In this respect, by providing the mattress assembly 10 with the bidirectional separation zipper 50, the first cover 20 can be simply opened by moving the zipper pull 53a and the slider body 52a, the zipper pull 53b and the slider body 52b in the opposite directions. Not only can the second cover 40 be easily removed (eg, to clean or replace the second cover 40), but the second cover 40 can be easily attached to the first cover 20 again.

  Further, by utilizing the bidirectional separating zipper 50, the slider main bodies 52a and 52b and the zipper pulls 53a and 53b are arranged on the bidirectional separating zipper 50, so that the slider main bodies 52a and 52b and the zipper pull 53a can be used when not in use. , 53b can be made invisible from the outside. Alternatively, the slider main bodies 52 a and 52 b and the zipper pulls 53 a and 53 b may be disposed along the outer peripheral portion 46 of the second cover 40. In this case, the risk of damage to the mattress assembly 10 or the mattress below the slider body 52a, 52b and the zipper pulls 53a, 53b is reduced. For example, as best shown in FIG. 5, the slider main bodies 52 a and 52 b may be disposed adjacent to the reinforcing cloth panel 54 located on the outer peripheral portion 46 of the second cover 40. The reinforcing fabric panel 54 helps protect the second cover 40 when the user begins to move the slider bodies 52a, 52b along the rails of the zipper 50 by picking one or both of the zipper pulls 53a, 53b, Further, the positions of the slider main bodies 52a and 52b and the zipper pulls 53a and 53b can be easily identified.

  Referring to FIGS. 1 to 6, it is possible to obtain the further advantage by the configuration of the second cover 40 and to improve the protection level of the overlay 70, the first cover 20, and the lower mattress enclosed by the first cover 20. Therefore, the bottom surface 44 of the second cover 40 may include a water-impermeable and vapor-permeable material. The water-impermeable and vapor-permeable material contained in the bottom surface 44 of the second cover 40 is, for example, expanded polytetrafluoroethylene (ePTFE, such as Gore-Tex (registered trademark) of WL Gore & Associates, Newark, Del.). ) Or the like. In this respect, the water-impermeable and vapor-permeable material contained in the bottom surface 44 of the second cover 40 is such that the liquid passes through the top surface 42 and the bottom surface 44 of the second cover 40 and the mattress overlay 70, the first cover 20 and the lower side. The steam or moisture is allowed to evaporate and move through the second cover 40 in the first cover 20 or the lower mattress.

  It is sufficiently breathable and allows air, heat and moisture to pass through the mattress assembly 10 while being soft and durable enough to be easy to clean and damage any part of the mattress assembly 10 In order to provide the first cover 20 and the second cover 40 that are used to help prevent interference, the first cover 20, the second cover 40, or both are typically constructed from a fabric. For example, in the embodiment shown in FIGS. 1 to 9, the second cover 40 is made of cotton. Accordingly, the second cover 40 can obtain sufficient durability to protect the mattress overlay 70 and the first cover 20, and can be washed in a washing machine and can be easily maintained. 20 can be removed, cleaned and reattached to the first cover 20. Of course, 100% cotton material, many other fabrics (eg silk), fabrics containing cotton in various proportions can be used in any of the mattress assemblies described herein, Can be selected and used for any mattress assembly or mattress of the desired application or type.

  In order to protect the lower mattress, in addition to the use of cloth, the first cover 20 and the second cover 40 typically incorporate one or more flame retardant materials into the first cover 20 and the second cover 40. By incorporating a flame retardant material (eg, fire socks) into the first cover 20, the first cover 20 and the second cover 40 provide a flame retardant barrier that sufficiently surrounds the lower mattress (eg, viscoelastic foam mattress). provide. Further, by incorporating the flame retardant material into the second cover 40, the second cover 40 is heated by the flame or the material in contact with the second cover 40 and becomes high temperature, and the lower mattress overlay 70 and the second cover 40 are heated. 1 It is easy to prevent damage to the cover 20.

  In order to further improve the comfort of the user of the mattress assembly 10, a charcoal sheet may be incorporated in the upper panel 122 of the first cover 20. The charcoal sheet removes or relieves odors and chemicals in or released from the mattress assembly 10 (specifically, the mattress wrapped in the first cover 20). For example, in some embodiments, the first cover 20 is used to enclose a newly manufactured mattress composed of flexible foam so that the charcoal sheet removes or relieves gas and odors originally present in the mattress. It becomes an effective means. Of course, the charcoal sheet may be incorporated into the second cover of the exemplary mattress assembly of the present invention without departing from the spirit and scope of the subject matter described herein. Further, while the charcoal sheet is not sufficiently toxic and can be easily incorporated into a mattress cover, it is used with the mattress assembly of the present invention, but the mattress assembly of the present invention removes odors or gases. Other means may be incorporated, such as drug-based coatings to remove odors or gases.

  In other exemplary embodiments of the invention, the top surface 42 of the second cover 40 of the mattress assembly 10 may incorporate a predetermined amount of phase change material. The phase change material taken into the top surface 42 of the second cover 40 is generally made of microspheres. Microspheres contain a substance with a high heat of dissolution and accumulate or release heat when the substance undergoes a phase change between a solid and a liquid (ie, it is a phase change material). The phase change material contained in the top surface 42 of the second cover 40 changes (ie, dissolves) from a solid to a liquid by heat generated by a user lying on the mattress assembly 10. This allows the phase change material to continuously absorb heat and provide a cooling effect to the user until all of the phase change material changes from solid to liquid. The phase change material may be taken into the top surface 42 by injecting microspheres of the phase change material into the top surface 42 of the second cover 40 and coating the top surface 42 with the microspheres. Of course, however, phase change material is injected only into the top surface 42 of the second cover 40 and / or phase change to sufficiently cool the user's body lying on the mattress assembly 10. The material need not be used to coat only the top surface 42 of the second cover 40, and phase change material may be injected into the bottom surface 44 of the second cover 40 or the upper panel 22 of the first cover 20 and / or the phase. The changing material may also be used to coat the bottom surface 44 of the second cover 40 or the upper panel 22 of the first cover 20.

  As a further improvement over the mattress assembly of the present invention, the mattress assembly 10 has a brand tag 62 attached to the foot panel 34 of the first cover 20. The brand tag 62 is large enough to display a logo and may be attached to the foot panel 34 using a variety of means such as adhesives, hook-and-loop fasteners, sewing, and the like. In some embodiments, unlike conventional brand tags where a fabric logo is sewn to a cover or mattress, the brand tag 62 is typically made of a sufficiently hard material (eg, plastic) and has an inner pocket. . In this regard, the brand tag 62 may be used to store various things that can be associated with the mattress assembly 10 (eg, the warranty content of the mattress assembly 10 or the lower mattress) in the inner pocket.

  As a further improvement to the mattress assembly of the present invention, the mattress assembly may have indicia provided on either the first cover, the second cover, or both. The indicia indicate the characteristics of the mattress and / or mattress overlay included in the mattress assembly and allow the user to see and identify the characteristics. The indicia may include a pattern, a color, or a combination of a pattern and a color, and may be disposed at various locations on the first cover and the second cover. For example, the mattress assembly 10 shown in FIGS. 1 to 6 is provided on the top surface 42 of the second cover 40 and has an interlocking circle pattern 80 as a mark.

  Regardless of the type and position of the mark, as described above, the mark is preferably used to display the characteristics of the mattress and / or mattress overlay included in the mattress assembly of the present invention. The characteristic is, but is not limited to, for example, the hardness or type (eg, spring, foam, etc.) of the mattress or mattress overlay included in the mattress assembly. Further, in some embodiments, multiple indicia indicating multiple characteristics for the mattress or overlay may be included.

  By placing indicia on the cover of the present invention, each cover described herein allows the mattress assembly to be marked to allow visual identification of mattress and / or mattress overlay characteristics. Can be used as part of In one example, a method for marking a mattress assembly to allow visual identification of the characteristics of the mattress and / or mattress overlay includes first a first cover for wrapping the mattress, a mattress overlay and a first Providing a mattress assembly with a second cover disposed on and covering at least the upper panel of the cover. Next, the top surface of the second cover is marked with a first mark indicating the first characteristic of the mattress and / or mattress overlay. This allows the user to identify the characteristics of the mattress and / or mattress overlay by simply looking at the mattress and combining the indicia with the characteristics (eg, the hardness and type of the mattress and / or mattress overlay). In an example, the foot panel of the first cover, the two opposing side panels, or both the two opposing side panels may be marked with a second mark. Here, the second mark indicates either the first characteristic or the second characteristic of the mattress and / or the mattress overlay.
