This document relates to a zoned temperature regulated bedding product. Some embodiments of the present disclosure are directed to a bedding product that includes a support layer, which includes temperature regulating material such as gel or gel foam and substrate material such as memory foam, where the temperature regulating material is arranged into temperature regulating zones along the surface of the support layer.
1 . A bedding product comprising:
a support layer comprising substrate material having a plurality of peaks and valleys arranged thereon; and
temperature regulating material, wherein the temperature regulating material is disposed on the peaks or valleys in one or more temperature regulating zones along an upper surface of the support layer, while areas of the support layer that do not correspond to temperature regulating zones are free from the temperature regulating material or have a lesser amount the temperature regulating material applied thereto.
2 . The bedding product of claim 1 , wherein:
the temperature regulating material comprises gel or gel foam; and
the substrate material comprises conventional foam, high resilience foam, latex foam rubber, viscoelastic foam, polyurethane foam, memory foam, slow recovery foam, ground foam, latex foam, reflex foam, continuous foam, hyper-soft resilient foam, hyper-soft high airflow viscoelastic foam, or combinations thereof.
3 . The bedding product of claim 2 , wherein the temperature regulating zones are positioned so that the temperature regulating zones coming into contact with at least one, but less than all, of the following parts of the body of a typical human user during use: head/neck, shoulders, waist, hips, and legs/feet.
4 . The bedding product of claim 3 , wherein the temperature regulating zones comprise raised sections having peaks that comprise the temperature regulating material.
5 . The bedding product of claim 5 , wherein the temperature regulating zones also comprise valleys that are free from the temperature regulating material.
6 . The bedding product of claim 3 , wherein the temperature regulating zones comprise channels formed into the support layer and at least partially filled with the temperature regulating material.
7 . A method for fabricating a bedding product with a zoned temperature regulating system, comprising:
providing a support layer comprising a foam substrate material;
forming a plurality of peaks and valleys into the support layer, wherein the peaks and valleys are selectively arranged in temperature regulating zones; and
dispersing temperature regulating material onto the peaks or valleys of one or more of the temperature regulating zones along an upper surface of the support layer, so that areas of the support layer that do not correspond to temperature regulating zones are free from the temperature regulating material or have a lesser amount the temperature regulating material applied thereto.
8 . The method of claim 7 , wherein forming the plurality of peaks and valleys into the support layer comprises, by a convoluter having a blade and a plurality of patterned rollers:
drawing the support layer across the blade to split the support layer; and
using the patterned rollers to impart the peaks and valleys on the support layer.
9 . The method of claim 7 , wherein forming the plurality of peaks and valleys into the support layer comprises, by a compression cutter:
compressing the support layer against a board that bears a pattern to form peaks and valleys in the support layer; and
cutting material from the support layer in compressed sections of the support layer.
10 . The method of claim 7 , wherein dispersing the temperature regulating material comprises:
by one or more support rollers of a roll coater, drawing the support layer between an applicator roller and the one or more support rollers so that the applicator roller applies the temperature regulating material to the peaks of one or more of the temperature regulating zones but does not apply the temperature regulating material to the valleys of the temperature regulating zones.
11 . The method of claim 10 , wherein dispersing the temperature regulating material also comprises operating the roll coater so that:
the applicator roller contacts the peaks when the temperature regulating zones pass through a gap between the applicator roller and the support rollers; and
when a portion of the support layer that does not include a temperature regulating zone passes through the gap, the applicator roller is moved away from the support rollers to expand the gap so that the applicator roller does not contact the portion of the support layer that does not include a temperature regulating zone.
12 . The method of claim 11 , wherein dispersing the dispersing the temperature regulating material also comprises operating the roll coater so that:
the applicator roller is positioned to cause the gap to have a first size when a first one of the temperature regulating zones passes through the gap; and
the applicator roller is positioned to cause the gap to have a second size when a second one of the temperature regulating zones passes through the gap, wherein the second size is larger than the first size but the applicator roller will still contact the peaks when the second temperature regulating zone passes through the gap.
13 . The method of claim 12 , wherein:
the first temperature regulating zone corresponds to a head/neck area or a waist area of the support layer, and
the second temperature regulating zone corresponds to a legs/feet area of support layer.
14 . The method of claim 7 , wherein the substrate material comprises conventional foam, high resilience foam, latex foam rubber, viscoelastic foam, polyurethane foam, memory foam, slow recovery foam, ground foam, latex foam, reflex foam, continuous foam, hyper-soft resilient foam, hyper-soft high airflow viscoelastic foam, or combinations thereof.
15 . The method of claim 7 , wherein the temperature regulating material comprises gel or gel-foam.
16 . A method for fabricating a bedding product with a zoned temperature regulating system, comprising:
providing a support layer comprising a foam substrate material;
forming a plurality of peaks and valleys into the support layer; and
by a roll coating device, dispersing temperature regulating material onto the peaks or valleys of one or more temperature regulating zones along an upper surface of the support layer, so that areas of the support layer that do not correspond to temperature regulating zones are free from the temperature regulating material or have a lesser amount the temperature regulating material applied thereto.
17 . The method of claim 16 , wherein dispersing the temperature regulating material comprises:
by one or more support rollers of the roll coating device, drawing the support layer between an applicator roller and the one or more support rollers so that the applicator roller applies the temperature regulating material to the peaks of one or more of the temperature regulating zones but does not apply the temperature regulating material to the valleys of the temperature regulating zones.
18 . The method of claim 16 , wherein dispersing the temperature regulating material also comprises operating the roll coating device so that:
the applicator roller contacts the peaks when the temperature regulating zones pass through a gap between the applicator roller and the support rollers; and
when a portion of the support layer that does not include a temperature regulating zone passes through the gap, the applicator roller is moved away from the support rollers to expand the gap so that the applicator roller does not contact the portion of the support layer that does not include a temperature regulating zone.
19 . The method of claim 18 , wherein dispersing the temperature regulating material also comprises operating the roll coating device so that:
the applicator roller is positioned to cause the gap to have a first size when a first one of the temperature regulating zones passes through the gap; and
the applicator roller is positioned to cause the gap to have a second size when a second one of the temperature regulating zones passes through the gap, wherein the second size is larger than the first size but the applicator roller will still contact the peaks when the second temperature regulating zone passes through the gap.
20 . The method of claim 16 , wherein:
the first temperature regulating zone corresponds to a head/neck area or a waist area of the support layer, and
the second temperature regulating zone corresponds to a legs/feet area of support layer.
