Integrated cooling lapdesk without electronics

Abstract

A cooling lapdesk comprises an interior cushion layer including a rear, a front, a left side and a right side, the rear being thicker than the front, the left and right sides having equal thickness at a given proximity to the front or rear, the interior layer elastic throughout its length and width. The cooling lapdesk also has a hollow exterior cover layer tightly surrounding and urged to be in contact with the interior layer on all sides of the interior layer, the exterior layer including a cooling top section integrally formed with the exterior layer, the cooling top section having a coolant such as granules of sodium sulfate decahydrate embedded therein, the granules capable of absorbing heat striking the cooling top section. The granules may be housed in compartments on the top surface of the top section of the exterior layer that are elevated.

1 . A cooling lapdesk, comprising:
 a foam cushion shaped to support a laptop computer; and   a cover tightly enclosing the foam cushion, the cover including a top section integrally formed with the cover and having granules embedded in the top section, the granules capable of absorbing heat and turning into a gel when heat from an object elevates a temperature of the granules to approximately 90 degrees Fahrenheit, the top section thereby cooling the object.   
     
     
         2 . The cooling lapdesk of  claim 1 , wherein the top surface is bumpy. 
     
     
         3 . The cooling lapdesk of  claim 1 , wherein the lapdesk has no fan or electronic components. 
     
     
         4 . The cooling lapdesk of  claim 1 , wherein the granules are sodium sulfate decahydrate. 
     
     
         5 . The cooling lapdesk of  claim 1 , wherein the cover is made of synthetic material and has a side with a zipper. 
     
     
         6 . A lapdesk adapted to absorb heat from a laptop computer striking a top surface of the lapdesk by means of a top section integrally formed with a cover, the cover enclosing and urged against an interior cushion layer, the top section using granules of sodium sulfate decahydrate embedded therein to absorb heat from the laptop computer striking the top surface of the lapdesk, the lapdesk also adapted to rest on a user's lap and support the laptop computer. 
     
     
         7 . The lapdesk of  claim 6 , wherein the top section has a top surface that includes elevated compartments housing the granules. 
     
     
         8 . The lapdesk of  claim 7 , wherein the elevated compartments are separated by valleys, the valleys forming a repeating pattern. 
     
     
         9 . The lapdesk of  claim 6 , wherein the top section has a non-slip surface. 
     
     
         10 . A cooling lapdesk, comprising:
 an interior layer including a rear, a front, a left side and a right side, the rear being thicker than the front, the left and right sides having equal thickness at a given proximity to the front or rear, the interior layer elastic throughout its length and width; and   a hollow exterior layer surrounding and urged to be in contact with the interior layer on all sides of the interior layer, the exterior layer including a cooling top section integrally formed with the exterior layer, the cooling top section having granules of sodium sulfate decahydrate embedded therein, the granules capable of absorbing heat striking the cooling top section.   
     
     
         11 . The cooling lapdesk of  claim 10 , wherein the granules are housed in compartments that are elevated. 
     
     
         12 . The cooling lapdesk of  claim 10 , wherein the cooling top section has elevated portions housing the granules and has valleys between the elevated portion that do not contain granules. 
     
     
         13 . The cooling lapdesk of  claim 10 , wherein the interior layer has a density of between 20 and 40 kg/m 3    
     
     
         14 . The cooling lapdesk of  claim 10 , wherein the exterior layer includes closure means for opening and closing the exterior layer. 
     
     
         15 . The cooling lapdesk of  claim 10 , wherein the granules turn into a gel when the granules reach a temperature of approximately 32.4 degrees Celsius. 
     
     
         16 . The cooling lapdesk of  claim 10 , wherein the top section is capable of absorbing the heat from a functioning laptop computer. 
     
     
         17 . The cooing lapdesk of  claim 10 , wherein the granules begin absorbing heat from an object when the granules exceed a temperature equal to approximately room temperature. 
     
     
         18 . The cooling lapdesk of  claim 10 , wherein the cooling lapdesk has no fan or electronic components.
