Description
- The present application is directed to a mattress and, more particularly, to a mattress with a vented cover for airflow into and out of an interior of the mattress.
- A mattress provides support for a person that is lying down and often sleeping. A mattress traditionally includes a core which is the internal substrate that provides mattress loft. The core may include a rectangular body sized to support the person. In some applications, the core may also include a pillow operatively connected to the body to further support the head and neck of the user.
- The mattress may also include a protective cover to protect the core from damage that may occur during use. The damage may be intentional, such as by the user ripping or tearing the mattress. Intentional damage is a major concern when the mattress is used in a correctional institution setting, such as a prison, jail, or detention facility. The user may intentionally damage the mattress to hide contraband or use the mattress as a weapon to either injure themselves or other persons.
- The cover includes a vent that allows airflow into and out of the interior of the mattress but limit the introduction of liquid and debris in the interior. The limiting of liquid and debris may prevent mold or other harmful agents from forming within the interior. The airflow may also make the mattress more comfortable for the user as the amount of air that remains within the interior changes depending upon the size and weight of the user. The vent is constructed to prevent the user from removing the vent and gaining access to the interior of the mattress.
- The present application is directed to a mattress with a core contained within a cover. The core may include a first end and a second end and first and second sides that extend between the ends. The first and second sides may each be configured to support the user. The cover may form an enclosed interior space to contain the core. The cover may include an exterior surface that is visible to the user and an interior surface that faces towards the core. The mattress may also include a plurality of pores that each extend through the cover and are positioned in an area of the cover. The plurality of pores may provide for air to move into and out of the interior space formed by the cover, and may limit the ingress of liquid or debris into the interior space.
- The various aspects of the various embodiments may be used alone or in any combination, as is desired.

Thebody 21 also includes atop side 25 and abottom side 26 that form the support surfaces for the user. One or both of thesides body 21 may be constructed from various materials, including but not limited to polyester, cotton, foam, inner springs, polyurethane, and latex. Thebody 21 may also be constructed from a combination of two or more of these materials. - The
pillow 22 is positioned to support the neck and head of the user. Thepillow 22 may be positioned at thesecond end 24 of thebody 21. Thepillow 30 includes afirst end 27 that faces towards thebody 20 and may contact or be spaced away from thesecond end 24. Thepillow 22 also includes afirst side 28 and an opposingsecond side 29. One or bothsides pillow 22 measured between thesides body 21 measured between thesides pillow 22 includes a greater height than thebody 21. In one specific embodiment, the height of thepillow 22 is twice the height of thebody 21. Thepillow 22 may also include one or more chamfers positioned at acute angles relative to the centerline C′. Thepillow 22 may be constructed from various materials, including but not limited to polyester, cotton, foam, latex, and polyurethane. Thepillow 30 may also be constructed from a combination of two or more of these materials. - The
cover 30 forms theinterior space 31 and extends around thecore 20. In embodiments with abody 21 andpillow 22, theinterior space 31 may be sized to allow for some movement of thepillow 22 relative to thebody 21. Thecover 30 protects thecore 20 from damage by liquid and other debris. Thecover 30 may provide an airtight and watertight exterior around the enclosedcore 20. Thecover 30 may be constructed from a variety of materials, including but not limited to polyvinyl chloride (PVC) vinyl. - The
cover 30 may include one or more seams that may be formed in a variety of manners included but not limited to heat sealing, ultrasonic and RF welding. The seams generally includehorizontal seams 32 andvertical seams 33 as illustrated inFIG. 2 . Thehorizontal seams 32 extend along the length of thecore 20 and are generally parallel with the centerlines C and C′. Thevertical seams 33 extend along the height of thecore 20 and are generally perpendicular to the centerlines C and C′. Thevertical seams 33 may be isolated to the corners of themattress 10 with a first pair ofvertical seams 33 at thefirst end 23 and a second pair at thesecond end 24. In one embodiment, thevertical seams 33 include a smaller height than the core 20 to provide for a more aesthetically pleasing appearance to thecover 30. - The
mattress 10 may be used with either thetop side 25 or thebottom side 26 facing upward to support the user. In a first orientation, thetop side 25 faces upward to support the user and thebottom side 26 contacting against a support surface, such as the ground, a bed frame, box spring, or the like. In an embodiment with thepillow 22 including a greater height, thetop side 28 of the pillow extends above thetop side 25 of thebody 21 to better support the user's neck and head. Themattress 10 may be used in a second orientation with thebottom side 26 facing upward to support the user and thetop side 25 facing downward and being in contact with the support surface. In the second orientation, thetop side 29 of thepillow 22 may extend upward beyond thebottom side 26 to support the user's neck and head when thepillow 22 includes a greater height than thebody 21. - Various embodiments of a mattress are disclosed in U.S. patent application Ser. No. 12/500,136 filed on the same day as the present application and herein incorporated by reference in its entirety.
- A
vent 40 extends through thecover 30 to provide airflow into and out of theinterior space 31. Thevent 40 may also allow air to exit from theinterior space 31 when a user initially sits or lies on themattress 10 as their weight causes the air to be forced through thevent 40. Conversely, air may enter back into theinterior space 31 through thevent 40 once the user exits themattress 10. This movement of air into and out of theinterior space 31 may provide a more comfortable feel for a variety of users as volume of air in theinterior space 31 adjusts depending upon the weight and movement of the user. -
FIG. 4 includes avent 40 with apatch 44 that extends over a plurality ofpores 41 formed through thecover 30. Thepores 41 are sized to allow the flow of air through thecover 30 yet limit entry of liquid and debris. The size of thepores 41 may vary. In some embodiments, the size ranges from about 24 gauge (6.1 microns) to about 60 gauge (15.2 microns). Each of thepores 41 may include the same size, or thepores 41 may include different sizes pores 41 may include the same size, or thepores 41 may include different sizes ranging from about 0.30 mm to about 50 mm. Thevent 40 may also include various numbers ofpores 41 and include different pore densities (the number of pores per a given area, such as a square inch). In some embodiments, the total number ofpores 41 in avent 40 ranges from about 1 to about 2400 pores per square inch. In some embodiments, avent 40 with a larger overall size may include substantially the same number ofpores 41 as asmaller vent 40. This is because thelarger vent 40 includes a smaller density ofpores 41 than thesmaller vent 40. Therefore, each of the smaller andlarger vents 40 is able to accommodate substantially the same amount of airflow into and out of theinterior space 31. The arrangement of thepores 41 may also vary with somevents 40 formed from arrays of aligned rows and/or columns ofpores 41 andother vents 40 formed from miscellaneous groupings. - The
pores 41 may be formed in a punching, pressing, or rolling operation in which a pin/platen/roll is forced through thecover 30 to form each of thepores 41. One process includes punching, pressing, or rolling the element through thecover 30 from theinterior surface 35 to theexterior surface 34, or in the opposite direction. This process forms a raisedlip 46 on theexterior surface 34 or theinterior surface 35 that surrounds each of thepores 41. The raisedlips 46 extend outward beyond theun-punched surface lips 46 may be formed by the deformation of thecover 30 that occurs during the punching process. -
FIG. 6 illustrates a magnified view of the raisedlips 46 that extend around thepores 41. In this embodiment, the raisedlips 46 extend outward beyond theexterior surface 34 of thecover 30. Other embodiments may include thelips 46 extending outward beyond theinterior surface 35. Each of thelips 46 may be the same, or thelips 46 may be different dependent on the punching, pressing, or rolling operation. The raisedlips 46 further shield thepores 41 and further limit the ingress of liquid and other debris. - The
vent 40 may also include apatch 44 that extends over thepores 41 and is attached to thecover 30. Thepatch 44 is constructed of a material that allows airflow into and out of theinterior space 31 but limits the ingress of liquid and debris. In one embodiment, thepatch 44 is constructed from POREX 0.007 MUPOR microporous polytetrafluoroethylene (PTFE) membrane fabric from Porex Technologies. Thepatch 44 may also be constructed from other materials, including but not limited to eVent Fabric from BHA Group, Inc., and GORETEX protective vents from W.L. Gore & Associates, Inc. - The
patch 44 may be attached to theinterior surface 35 of thecover 35 as illustrated inFIG. 5A and is sized to extend over thepores 41. Aseal 45 attaches thepatch 44 to thecover 35. Theseal 45 may be formed by a variety of applications, including but not limited to adhesive, stitching, heat sealing, and ultrasonic and RF welding. Theseal 45 extends completely around thepatch 44. - Positioning the
patch 44 on theinterior surface 35 hides thepatch 44 from the user as illustrated inFIG. 5B and may provide several advantages. Thepatch 44 is not visible and therefore may increase the aesthetic appearance of themattress 10. The positioning also protects thepatch 44 from possible damage that could result during normal use of themattress 10. One example of normal use damage includes thepatch 44 snagging on an object such as the user clothing and being torn from thecover 44. The positioning also prevents the user from intentionally tampering with thepatch 44 and attempting to gain access to theinterior space 31. This aspect is of particular interest when themattress 10 is used in a correctional institution. - The
pores 41 are of such a small size as to not be readily noticeable when viewing theexterior surface 34 of thecover 30. The visible masking of thepores 41 may also include attaching apatch 44 that is substantially the same color as theexterior surface 34 of thecover 30. This aspect increases the aesthetic appearance of themattress 10 and may further prevent tampering with thevent 40 in an attempt to gain access to theinterior space 31. - In one embodiment the
patch 44 is attached to theexterior surface 34 of thecover 30. Theseal 45 provides a secure attachment to prevent removal of thepatch 44 either by accidental or intentional tampering. - The
vent 40 may be positioned at various locations about themattress 10. In one embodiment, thevent 40 is positioned in asidewall 58 between the top andbottom surfaces body 21 and apillow 22, thevent 40 is positioned at thefirst end 23 away from thepillow 22. Further, the size of thevent 40 may include extending along a substantial portion of themattress 10. In one embodiment, thevent 40 extends along almost an entirety of thesidewall 58 between the first and second ends 23, 24. - The
mattress 10 may also include more than onevent 40. Thevents 40 may include the same or different shapes, sizes, and pore density. Thevents 40 may also be positioned at the same or different locations on themattress 10. -
