Composite cleaning device for an automobile

Abstract

An elongated pie shaped composite cleaning device for removing snow, frost, scraped ice debris, bird droppings, dirt or water from a automotive exterior surface has 1. a stiff rectangular plastic sheet, folded into half, providing a pair of slightly curbed exterior sides and a pair of substantially straight scraping edges, 2. a rectangular open cell foam, with a uniform thickness and shape substantially identical to said sheet, folded into half, providing a pair of legs between said sides, a squeezed interface between said legs and a pair of exposure cleaning faces, 3. a thin retaining rod surrounded by the folded middle parts of said sheet and said foam, and 4. a fabricated channel shape holder clamping said folded sheet, said folded foam around said retaining rod and having a means of securely attaching to a handle and either a ice scraper or a squeegee.

1 . An elongated pie shaped composite cleaning device for a smooth mildly curved or flat surface comprising: 
 a stiff rectangular plastic sheet, folded into half, providing a pair of slightly curbed exterior sides and a pair of substantially straight scraping edges,    a rectangular open cell foam, with a uniform thickness and shape substantially identical to said sheet, folded into half, providing a pair of legs between said sides, a squeezed interface between said legs and a pair of exposure cleaning faces,    a thin retaining rod surrounded by the folded middle parts of said sheet and said foam, and    a fabricated channel shape holder clamping said folded sheet, said folded foam around said retaining rod and having a means of securely attaching to a handle and either a ice scraper or a squeegee.    
   
   
       2 . The cleaning device of  claim 1  wherein said plastic sheet is an extruded HDPE.  
   
   
       3 . The cleaning device of  claim 1  wherein said foam is a polyester foam or polyurethane foam.  
   
   
       4 . The cleaning device of  claim 1  wherein said holder and is shorter than said folded sheet to prevent said holder touching or scratching the surface.  
   
   
       5 . The cleaning device of  claim 1  wherein said holder is fabricated from a rectangular stainless steel blank.  
   
   
       6 . The cleaning device of  claim 1  wherein both legs of said holder are bent toward each other to stiffen said device from bending and tighten the clamping.  
   
   
       7 . The cleaning device of  claim 1  wherein said means of attaching is a substantially rectangular opening formed by the middle part of slit part of the legs and stretched and formed portion of the web of said holder.  
   
   
       8 . The cleaning device of  claim 7  wherein said squeezed interface holds a concentrated solution and progressive release at lower concentration.
