Abstract

A temperature controlled blanket for providing dual warming and cooling zones. The temperature controlled blanket comprises a first layer of material, a second layer of material, and a seam, wherein the seam is disposed along a longitudinal axis of each layer of material, such that the seam defines a first portion and a second portion of the blanket. The first portion and the second portion each contain a panel comprising heating and cooling elements disposed between the first layer of material and second layer of material. The blanket further comprises at least one thermostat operably connected to each panel of the first portion and the second portion and a power source, wherein the at least one thermostat individually controls the heating and cooling elements of each panel. In an alternative embodiment, the first portion and the second portion of the second layer of material are made of two differing fabrics.

Claims

1. A temperature controlled blanket, comprising:

a first layer of material and a second layer of material, wherein the first layer of material and the second layer of material are affixed to one another along an outer perimeter of each layer creating an enclosed interior volume;

a seam, wherein the seam is disposed along a longitudinal axis of the first layer of material and the second layer of material, such that the seam defines a first portion and a second portion;

wherein the first portion of the first layer of material and the first portion of the second layer of material are made of a first pair of fabrics;

wherein the second portion of the first layer of material and second portion of the second layer of material are made of a second pair of fabrics;

wherein the first pair of fabrics comprises at least one different fabric other than the second pair of fabrics;

wherein the first portion and the second portion each contain a panel comprising heating and cooling elements disposed within the enclosed interior volume between the first layer of material and the second layer of material;

at least one thermostat operably connected to each panel of the first portion and the second portion, wherein the at least one thermostat is configured to separately control the heating and cooling elements of each panel; and

a power source, wherein the power source is operably connected to the first panel and the second panel.

2. The temperature controlled blanket of claim 1, wherein the first layer of material of the first portion and the second portion is a first fabric, the second layer of material of the first portion is a second fabric, and the second layer of material of the second portion is a third fabric.

3. The temperature controlled blanket of claim 2, wherein the first fabric is cotton, the second fabric is fleece, and the third fabric is cotton.

4. The temperature controlled blanket of claim 1, wherein the at least one thermostat is a digital thermostat.

5. The temperature controlled blanket of claim 4, wherein the digital thermostat contains a digital screen and a control knob.

6. The temperature controlled blanket of claim 1, wherein the first layer of material and the second layer of material comprise a rectangular shape.

7. The temperature controlled blanket of claim 1, wherein the outer perimeter is configured to match a perimeter of a bed.

8. The temperature controlled blanket of claim 1, wherein each the first portion and the second portion are configured to cover a user.

9. The temperature controlled blanket of claim 1, wherein the power source is an electrical cord.

10. The temperature controlled blanket of claim 1, wherein the at least one thermostat comprises a pair of thermostats operably connected to each panel of the first portion and the second portion, wherein a first thermostat individually controls the heating and cooling elements of a first panel and a second thermostat individually controls the heating and cooling elements of a second panel.

11. The temperature controlled blanket of claim 1, wherein the first portion and the second portion are equal in size and shape.
