Allergy barrier for bedding

Abstract

An allergy barrier for bedding comprised of a sheet adapted to fit a wide variety of mattress depths by enclosing a top, all sides, and a portion of the bottom of a mattress. A pull string inserted within an outer hem of the sheet where the pull string is adapted to secure the sheet to the mattress. The pull string terminates outside of the outer hem. The sheet is made of a material having a mean average pore size of less than ten (10) microns.

       6 . The allergy barrier of  claim 1  where said outer hem of said sheet forms substantially a rectangle on the under side of said mattress, said rectangle having four corners, and four sides and further comprising eight pull string ends, two in each corner adapted for securely gathering material of said sheet in each corner, where pull string ends terminate outside said outer hem. 
   
   
       7 . The allergy barrier of  claim 6  further comprising a locking device for each pair of pull string ends. 
   
   
       8 . The allergy barrier of  claim 6  further comprising a tack point located about center of each side of said outer hem. 
   
   
       9 . The allergy barrier of  claim 6  further comprising a reinforced orifice in each corner adapted to journal said pull string ends. 
   
   
       10 . The allergy barrier of  claim 1  where said material is selected from the group consisting of: a microporous film; a tightly woven fabric; a nonwoven fabric; a woven fabric; or a laminate of one or more of the above listed fabrics or films. 
   
   
       11 . An allergy barrier for bedding comprising:
 a sheet adapted to fit a wide variety of mattress depths by enclosing a top, all sides, and a portion of the bottom of a mattress;   said sheet being made of a material having a mean average pore size of less than ten (10) microns;   said material being selected from the group consisting of: a microporous film; a tightly woven fabric; a nonwoven fabric; a woven fabric; or a laminate of one or more of the above listed fabrics or films;   where said sheet has no exposed enclosure means on said top and all sides;   a plurality of pull strings inserted within an outer hem of said sheet;   said pull strings being adapted to secure said sheet to said mattress;   where said outer hem of said sheet forms substantially a rectangle on an under side of said mattress, said rectangle having four corners, and four sides and further comprising eight pull string ends, two in each corner adapted for securely gathering material of said sheet in each corner;   where pull string ends terminate outside said outer hem; and   a reinforced orifice in each corner adapted to journal said pull string ends.   
   
   
       12 . The allergy barrier of  claim 11  where said sheet having no exposed enclosure means on said top and all sides. 
   
   
       13 . The allergy barrier of  claim 11  further comprising a tack point located about center of each side of said outer hem. 
   
   
       14 . The allergy barrier of  claim 11  where said sheet being adapted to easily be applied or removed by a single person. 
   
   
       15 . The allergy barrier of  claim 11  further comprising a locking device for said pull string. 
   
   
       16 . The allergy barrier of  claim 11  where said sheet is made of a tightly knit synthetic fabric. 
   
   
       17 . The allergy barrier of  claim 11  where said reinforced orifice is selected from the group consisting of: plastic, metal, fiber stitched reinforcing or a combination thereof. 
   
   
       18 . An allergy barrier for bedding comprising:
 a sheet adapted to fit a wide variety of mattress depths by enclosing a top, all sides, and a portion of the bottom of a standard mattress;   a pull string inserted within an outer hem of said sheet;   said pull string being adapted to secure said sheet to said mattress; and   said sheet being made of a material that is not porous.   
   
   
       19 . The allergy barrier of  claim 9  where said sheet having no exposed enclosure means on said top and all sides. 
   
   
       20 . The allergy barrier of  claim 9  where said sheet being adapted to easily be applied or removed by a single person.
