Title: Bedding or Seating Product Having Topper With At Least One Thermally Enhanced Foam Component

Description:
CROSS-REFERENCE TO RELATED APPLICATIONS 
     This application is a Continuation of U.S. patent application Ser. No. 17/245,629 filed Apr. 30, 2021 (pending), the disclosure of which is incorporated by reference herein. 
    
    
     TECHNICAL FIELD OF THE INVENTION 
     This invention relates to a topper for bedding and seating products. More particularly, this invention relates to a topper comprising a pocketed spring comfort layer sandwiched between foam components. 
     BACKGROUND OF THE INVENTION 
     Pocketed spring comfort layers have been used in seating or bedding products above/below a core of the bedding or seating product. The core of the bedding or seating product may comprise a pocketed spring assembly. Alternatively, the core of the bedding or seating product may comprise un-pocketed metal coil springs joined into a spring assembly. Another alternative for the core of the bedding or seating product may be one or more pieces of foam. 
     The pocketed spring comfort layers may comprise two pieces of fabric welded around metal mini coil springs as disclosed in U.S. Pat. Nos. 9,968,202 and 9,943,173, which are each fully incorporated by reference herein. Such comfort layers commonly have one layer of fabric above and one layer of fabric below mini coil springs. The fabric may allow air to flow between pockets and into and out of the pockets. 
     U.S. Pat. Nos. 10,329,469, 10,973,339, 10,750,877, and 10,738,228 and U.S. Patent Publication No. 2020/0317978, each of which is fully incorporated by reference herein, disclose foam infused with thermally conductive materials such as metals, graphite, silicon carbide, carbon nanotubes. The thermally conductive materials are spread throughout the foam in-situ. However, such infused foams have not been used in toppers like the toppers disclosed herein having a pocketed spring comfort layer included in the topper. 
     Mattress manufacturers have created a topper comprising a pocketed spring comfort layer between two pieces of non-thermally enhanced foam above a core of a bedding or seating product so that a user does not detect or feel the pocketed spring comfort layer. However, the thermally enhanced foams disclosed herein have not been used in such a topper to dissipate heat away from the user. 
     One drawback to known toppers is that heat from a person sleeping on the bedding product or mattress builds underneath the person due to the foam of the comfort layer. Such heat may cause a user to lose sleep or not sleep as well as if the mattress were cooler. The same may occur in a seating product in which case a person seated on the product may become uncomfortably hot in his/her part of the body contacting the seating product. 
     It is therefore an objective of this invention to provide a topper including a pocketed spring comfort layer adapted to overlay a core of a seating or bedding product to reduce heat underneath the user. 
     It is another objective of this invention to provide a seating or bedding product having a topper covering a core, the topper including a pocketed spring comfort layer sandwiched between layers of foam, at least one of the layers of foam being thermally enhanced foam for purposes of providing reducing heat below a person. 
     It is another objective of this invention to provide a seating or bedding product having a core and a topper covering the core, the topper including a pocketed spring comfort layer sandwiched between layers of thermally enhanced foam for cooling purposes. 
     SUMMARY OF THE INVENTION 
     The invention, which accomplishes these objectives, comprises a topper configured to overlay a core of a seating or bedding product. The topper comprises a first or upper piece of foam, a second or lower piece of foam and a pocketed spring comfort layer therebetween. In a single-sided bedding or seating product, a three-layered topper is located above a core of the bedding or seating product. In a double-sided bedding or seating product, a three-layered topper may be above the core and another three-layered topper may be below the core. 
     The pocketed spring comfort layer may be any known pocketed spring comfort layer. One type of pocketed spring comfort layer comprises an assembly or matrix of individually pocketed mini coil springs. The pocketed spring comfort layer comprises a first piece of fabric on one side of the mini coil springs and a second piece of fabric on the other side of the mini coil springs. The first and second pieces of fabric are joined by weld seams at least partially surrounding each of the mini coil springs, thereby creating pockets. In most embodiments, the first and second pieces of fabric are permeable to airflow. In many embodiments, the first and second pieces of fabric are made of non-woven polypropylene material, commonly used in the bedding industry. 
     In one embodiment of topper, the first and second pieces of foam, on opposite sides of the pocketed comfort layer, are thermally enhanced. For purposes of this document, a thermally enhanced piece of foam means the piece of foam has thermally conductive or heat absorbing materials in the form of powders, flakes, particles and the like incorporated or infused into the piece of foam in-situ. Examples of such thermally conductive materials include but are not limited to the following: metallic particles, carbon fibers, carbon nanotubes, silicon carbide, synthetic diamond, boron nitride and carbon nanoplatelets. Examples of heat absorbing materials include but are not limited to the following: microencapsulated phase change materials and gel materials. 
     At least one of the first and second pieces of foam may be flexible polyurethane or latex foam. It is within the scope of the present invention that the first and second pieces of foam, whether thermally enhanced or coated, may be identical. For example, one of the first and second pieces of foam may be made of flexible polyurethane and thermally enhanced while the other of the first and second pieces of foam may be made of flexible polyurethane and not thermally enhanced. 
     Alternatively, the first and second pieces of foam may be made of different foams. For example, one of the first and second pieces of foam may be made of flexible polyurethane and the other of the first and second pieces of foam may be made of latex. 
     According to another aspect of the invention, at least one of the first and second pieces of thermally enhanced foam may have a coating thereon. The coating usually covers only one outer surface of the piece of foam but may cover only a portion of a surface of the piece of foam. Alternatively, the coating may cover multiple outer surfaces of the piece of foam. The coating has thermal benefits such as having heat absorption or heat conductivity. The coating may have improved heat absorption characteristics due to microencapsulated phase change materials or gel materials incorporated into the coating. The coating may have improved thermal conductivity due to metallic or non-metallic particles being incorporated or infused into the coating. In either piece of foam, the coating is preferably proximate the pocketed spring comfort layer of the three-piece topper. However, the coating may cover at least a portion of the top and below outer surfaces of the piece of foam. 
     According to one embodiment of the invention, only the first piece or layer of foam above the pocketed spring comfort layer is thermally enhanced. The second piece or layer of foam inside the pocketed spring comfort layer may not be thermally enhanced. In some embodiments, the first piece of foam is infused with metallic particles. In other embodiments, the first piece of foam is infused with at least one of the following: carbon fibers, carbon nanotubes, microencapsulated phase change materials, silicon carbide, synthetic diamond or boron nitride. In embodiments in which only the first piece of foam is thermally enhanced, at least one of the first and second pieces of foam may have a coating thereon as described herein. 
     Any of the toppers shown or described herein may be incorporated into a bedding product, such as a mattress, mattress topper or pillow. Further, any of the embodiments of topper shown or described herein may be incorporated into a seating product, such as a vehicle seat and/or office or residential furniture, such as a recliner. Alternatively, any of the embodiments of topper shown or described herein may be sold independently as a retail or wholesale item. In such an application, the topper may be added to and/or removed from a bedding or seating product by a customer. 
     The topper of the present invention, whether incorporated inside a bedding or seating product, or manufactured and sold as a separate product, provides an additional cooling effect to the product due to conduction or convection through at least one piece of foam of the topper. 
     These and other objects and advantages of this invention will be more readily apparent from the following drawings, in which:

     DETAILED DESCRIPTION OF THE DRAWINGS 
     With reference to  FIG.  1   , there is illustrated a single-sided mattress  10  incorporating one embodiment of topper  14  in accordance with this invention. This mattress  10  comprises a spring core  12  over the top of which there is a topper  14 . The topper  14  comprises a first or outer foam piece  16 , a pocketed spring comfort layer  18  and a second or inner foam piece  20 . As shown in  FIG.  1   , the first foam piece  16  is located above the pocketed spring comfort layer  18  and the second piece of foam  20  is below the pocketed spring comfort layer  18 . This complete assembly may include a base  19  and is completely enclosed within an upholstered cover  22 . 
     As shown in  FIG.  1   , mattress  10  has a longitudinal dimension or length L, a transverse dimension or width W and a height H. Although the length L is shown as being greater than the width W, they may be identical. The length, width and height may be any desired distance and are not intended to be limited by the drawings. 
     In most embodiments, the first piece of foam  16  is secured to the pocketed spring comfort layer  18 ; so is the second piece of foam  20 . The first and second pieces of foam  16 ,  20  are usually glued to the pocketed spring comfort layer  18  with adhesive. However, any other means of securing the first and second pieces of foam  16 ,  20  to the pocketed spring comfort layer  18  may be used. In other embodiments, one or both of the first and second pieces of foam may not be secured to the pocketed spring comfort layer  18 . It is also within the scope of the present invention that the topper  14  has its own covering. 
     Although spring core  12  is illustrated being made of pocketed coil springs, the core of any of the products, such as mattresses shown or described herein, may be made wholly or partially of un-pocketed coil springs (not shown), one or more foam pieces (not shown) or any combination thereof. Any of the toppers described or shown herein may be used in any single or double-sided bedding or seating product having any core. The core may be any conventional core including, but not limited to, pocketed or un-pocketed spring cores. The novel topper of the present invention provides a cooling effect to a person laying on the spring core  12 . 
       FIG.  2    illustrates a double-sided mattress  10   a  comprising a spring core  12  and toppers  14  above and below the spring core  12 . The topper  14  below the spring core  12  is flipped relative to the topper  14  above the spring core. In other words, the first piece of foam  16  is always exterior to the second piece of foam  20 . While toppers  14  shown in detail in  FIG.  3    are shown in  FIGS.  1  and  2   , any topper shown or described herein may be used in connection with any single-sided mattress or double-sided mattress including mattresses shown or described herein. 
       FIG.  3    illustrates the components of one embodiment of topper  14  incorporated into the mattress  10  shown in  FIG.  1    and mattress  10   a  shown in  FIG.  2   . The topper  14  comprises a first or outer piece of thermally enhanced foam  16 , a pocketed spring comfort layer  18  and a second or inner piece of foam  20 . The second or inner piece of foam  20  is not thermally enhanced and may be any flexible polyurethane or latex foam. 
     The pocketed spring comfort layer  18  may be any known pocketed spring comfort layer made with first and second pieces of fabric  24 ,  26 , respectively, permeable to airflow. In some embodiments the fabric may be non-woven polypropylene. As shown in  FIGS.  3  and  3 A , the first and second pieces of fabric are welded together with weld seams  28  creating pockets  30  containing mini coil springs  32 . Although  FIG.  3 B  illustrates one embodiment of pocketed spring comfort layer  18 , any known pocketed spring comfort layer may be used in any of the toppers of the present invention. 
     One mini coil spring  32  in a relaxed condition may be approximately two inches tall, have a diameter of approximately three inches and be made of seventeen and one-half gauge wire. While compressed inside one of the pockets  30 , each of the mini coil springs  32  may be approximately one and one-half inches tall. However, the mini coil springs  32  in a relaxed condition may be any desired height less than four inches, have any desired shape, such as an hourglass or barrel shape, have any desired diameter and/or be made of any desired wire thickness or gauge. 
     The first or outer piece of thermally enhanced foam  16  has at least some of the following particles infused therein: metallic particles, carbon fibers, carbon nanotubes, microencapsulated phase change materials, silicon carbide, synthetic diamond, boron nitride. As shown in  FIG.  3   , the first or outer piece of thermally enhanced foam  16  allows heat in the form of hot air to escape the interior of the mattress by passing through the first or outer piece of thermally enhanced foam  16  and through the pocketed spring comfort layer  18  as indicated by the arrows  34 . 
       FIG.  3 A  illustrates a load placed on the mattress  10 , the load being shown by the arrows  36 . When a load is placed on top of the mattress  10 , the topper  14  is compressed. The thermally conductive particles in the first or outer piece of thermally enhanced foam  16  move closer together than when the first or outer piece of thermally enhanced foam  16  is relaxed or not under a load. Thus, heat is passed from particle to particle in a conductive manner, thereby moving heat in the direction of arrows  34  away from the user of the product or mattress and out through the fabric of the pocketed spring comfort layer  18 . 
       FIG.  4    illustrates an alternative embodiment of topper  14   a  which may be incorporated into any bedding or seating product including single-sided mattress  10  or double-sided mattress  10   a.  Topper  14   a  comprises the same first or outer piece of thermally enhanced foam  16  and same pocketed spring comfort layer  18  as the topper  14  shown in  FIGS.  3  and  3 A . However, topper  14   a  further comprises a second or inner piece of thermally enhanced foam  36 , rather than a convention, non-thermally enhanced piece of flexible polyurethane or latex foam. The second or inner piece of thermally enhanced foam  36  may made of the same material as the first or outer piece of thermally enhanced foam  16 . Alternatively, the second or inner piece of thermally enhanced foam  36  may made of a different material as the first or outer piece of thermally enhanced foam  16 . Regardless of whether the second or inner piece of thermally enhanced foam  36  is made of the same foam as the first or outer piece of thermally enhanced foam  16 , the first and second thermally enhanced pieces of foam  16 ,  36  may have different particles infused therein or the same particles in different densities. 
       FIG.  5    illustrates an alternative embodiment of topper  14   b  which may be incorporated into any bedding or seating product including a single-sided mattress like mattress  10  or a double-sided mattress like mattress  10   a.

The coated first or outer piece of non-thermally enhanced foam  40  of topper  14   c  has a coating  42  covering at least a portion of an outer surface  44  thereof. As shown in  FIG.  5   , the coating  42  is proximate the pocketed spring comfort layer  18 . As shown in  FIG.  5   , the coating  42  may touch or physically contact the first piece of fabric  24  of the pocketed spring comfort layer  18 . The coating  42  may be any desired thickness. Its thickness is not intended to be limited by the drawings. The second or inner piece of foam  20  may made of the same foam as the first or outer piece of foam  40  or alternatively made of a different foam. One type of coating is disclosed in U.S. patent application Ser. No. 17/197,193, which is fully incorporated by reference herein.

As shown by dashed line  73 , another coating layer may be adhered to the second piece of fabric  26  of the pocketed spring comfort layer  75 . The second piece of non-thermally enhanced foam  81  may made of the same foam as the first or outer piece of thermally enhanced foam  79  or alternatively made of a different foam. 
       FIG.  13    illustrates an alternative embodiment of topper  14   g  which may be incorporated into any bedding or seating product including a single-sided mattress like mattress  10  or a double-sided mattress like mattress  10 a. Topper  14   g  comprises a first or outer piece of thermally enhanced foam  83  and a second or inner piece of thermally enhanced foam  85 . However, topper  14   g  has the same coated, pocketed spring comfort layer  75  as topper  14   e  shown in  FIG.  11   . As shown by dashed line  73 , another coating layer may be adhered to the second piece of fabric  26  of the pocketed spring comfort layer  75 .The second piece of thermally enhanced foam  85  may made of the same foam as the first or outer piece of thermally enhanced foam  83  or alternatively made of a different foam. 
       FIG.  14    illustrates a double-sided mattress  80  having two end sections  84  and a lumbar or middle section  86  therebetween. The double-sided mattress  80  has a posturized topper  82  above a pocketed spring core  12 . The same posturized topper  82  is flipped and located below the pocketed spring core  12 . Posturized topper  82  has three different areas or regions of firmness or heat management/movement depending upon the composition of the topper within each of the areas or regions. Posturized topper  82  comprises two end sections  91  on opposite sides of a middle section  93 . The middle section  93  is designed to transfer heat away from a person sleeping on the double-sided mattress  80  more efficiently than the end sections  84 , because the part of a person&#39;s body resting upon the middle section is typically hotter than the parts of a person&#39;s body resting on the end sections of the mattress. 
     Although three sections are illustrated in the drawings, any number of sections may be incorporated into a posturized topper. Although each of the sections is illustrated being a certain size, they may be other sizes. The drawings are not intended to be limiting. One or more of the areas/sections may feel cooler or dissipate heat more quickly due to the topper in one area/section having more thermally enhanced pieces of foam than the other areas/sections. The areas/sections may be any desired orientation or size; the drawings are not intended to be limiting. 
     As shown in  FIG.  15   , each of the end sections  91  of posturized topper  82  has upper and lower pieces of non-thermally enhanced foam  95  with a pocketed spring comfort layer  18  therebetween. The middle section  93  of posturized topper  82  has upper and lower pieces of thermally enhanced foam  97  with a pocketed spring comfort layer  18  therebetween. Thus, the middle section  93  of posturized topper  82  is more efficient at moving heat away from the double-sided mattress  80  than the end sections  91  of posturized topper  82 . It is within the scope of the present invention that any of the toppers described herein may be used in any sections of a posturized bedding or seating product. 
       FIG.  16    illustrates a different posturized double-sided mattress  90  having two end sections  94  and a lumbar or middle section  96  therebetween. The double-sided mattress  90  has a posturized topper  92  above a pocketed spring core  12 . The same posturized topper  92  is flipped and located below the pocketed spring core  12 . Posturized topper  92  has three different areas or regions of firmness depending upon the composition of the topper within each of the areas or regions. Posturized topper  92  comprises two end sections  101  on opposite sides of a middle section  103 . The middle section  103  of posturized topper  92  is designed to transfer heat away from a person sleeping on the double-sided mattress  90  more efficiently than the end sections  101  of posturized topper  92 , because the part of a person&#39;s body resting upon the middle section is typically hotter than the parts of a person&#39;s body resting on the end sections of the mattress. 
     As shown in  FIG.  16   , each of the end sections  101  of posturized topper  92  has upper, lower, and middle pieces of non-thermally enhanced foam  95 . In place of three pieces of non-thermally enhanced foam  95 , a single piece of non-thermally enhanced foam may be used in each of the end sections  101  of posturized topper  92 . The middle section  103  of posturized topper  92  has upper and lower pieces of thermally enhanced foam  97  with a pocketed spring comfort layer  18  therebetween. Thus, the middle section  103  of posturized topper  92  is more efficient at moving heat away from the double-sided mattress  90  than the end sections  101  of posturized topper  92 . It is within the scope of the present invention that any of the toppers described herein may be used in any sections of a posturized bedding or seating product. 
     Although  FIGS.  14 - 16    illustrate a double-sided mattress, the same inventive concepts of posturized toppers may be used in a single-sided mattress or any other bedding or seating product.
