Ergonomic framework for Chinese and Western chess pieces

Abstract

The ergonomic framework resembles a pyramid but with small rectangular peak ( 2 ), large rectangular base ( 8 ), two large isosceles trapezoid surface ( 5 a ) and ( 5 b ) on two side symmetrically face away from each other, and two small isosceles trapezoid surface ( 3 a ) and ( 3 b ) on two side symmetrically face away from each other. Said two large identical isosceles trapezoid surfaces are the primary display surfaces to display symbols that represent a particular chess piece. The angle between said large isosceles trapezoid surfaces is 41.85 degrees. If we set the length of the longer base of said two large isosceles trapezoid surfaces each to be 1.0 the length of the respective shorter bases will be 0.68, the height of said small rectangular peak will be 0.85, the widths of said small rectangular peak will be 0.20, the widths of said large rectangular base will be 0.85, and the sides of the four isosceles trapezoid surfaces will be 0.91.

1 . An ergonomic framework for Chinese and Western chess pieces comprising:
 (a) a small rectangular peak,   (b) a large rectangular base parallel to said small rectangular peak, line up its mid-point with the mid-point of said small rectangular peak on a vertical axis that is perpendicular to said small rectangular peak and said large rectangular base, said large rectangular base's lengths are parallel to the lengths of said small rectangular peak, said large rectangular bases' widths are parallel to the widths of said small rectangular peak,   (c) two large isosceles trapezoid surfaces of equal shape and size, symmetrically face away from each other, separated by said small rectangular peak and said large rectangular base, jointed each of their shorter bases' length with each of the lengths of said small rectangular peak, each their longer bases' length are jointed with each of the lengths of said large rectangular base, thus each of said two large isosceles trapezoid's shorter base is also one of the length of said small rectangular peak, and each of said two large isosceles trapezoid's longer base is also one of the length of said large rectangular base, and   (d) two small isosceles trapezoid surfaces of equal shape and size symmetrically face away from each other, separated by said small rectangular peak and said large rectangular base, completely filled the missing surfaces of aforementioned items (a), (b), and (c) to form one solid pyramid-like object of rectangular base, rectangular peak, and isosceles trapezoids on four sides,   
     whereby items (a), (b), (c), and (d) defines a basic structure that unify the handling of individual chess pieces, and provide a visually improved display platform for artist or designer to display symbols that represent particular Chinese chess piece or Western chess pieces on said two large identical isosceles trapezoid surfaces using whatever mean or technique that is necessary in their disposal include but not limited to drawing, painting, pad printing, stamping, engraving, labeling, in-mold labeling, carving, cut extrude, and extrude. 
   
   
       2 . The ergonomic framework of  claim 1  wherein said basic structure has all the edges rounded. 
   
   
       3 . The ergonomic framework of  claim 1  wherein said basic structure has all the edges rounded except the base edges. 
   
   
       4 . The ergonomic framework of  claim 1  wherein said basic structure is shelled from said large rectangular base. 
   
   
       5 . The ergonomic framework of  claim 4  wherein said basic structure is shelled from said large rectangular base has internal display surfaces ( 4   a ) and ( 4   b ) where particular chess piece can be defined on, provided the material use to create said basic structure is transparent or semitransparent. 
   
   
       6 . The ergonomic framework of  claim 1  wherein said basic structure is not shelled from said large rectangular base. 
   
   
       7 . The ergonomic framework of  claim 1  wherein said two large isosceles trapezoid surfaces' shorter base's length does not exceed 0.90 and does not less than 0.20 with respect to the longer bases' length. 
   
   
       8 . The ergonomic framework of  claim 1  wherein said large rectangular base has its width shorter than its length. 
   
   
       9 . The ergonomic framework of  claim 1  wherein said small rectangular peak has its width shorter than its length. 
   
   
       10 . The ergonomic framework of  claim 1  wherein said large rectangular base has width to length ratio of one to one. 
   
   
       11 . The ergonomic framework of  claim 1  wherein said small rectangular peak has width to length ratio of one to one.
