Device for the reduction in the diameter of a basketball rim

Abstract

A basketball rim attachment device for decreasing the diameter of the circular rim to increase shooting accuracy, having an annular rim insertion device for insertion onto the circular rim; and a plurality of hooking apertures upon the annular rim insertion device for attachment to the rim in a manner that provides substantially rigid conformity with the rim when applied and removability when not applied. The device is made from materials selected from the group consisting of plastics, polvinyls, polyurethanes, rubber, and metallic materials. The hooking apertures are generally between 110 degrees and 270 degrees in cross-section. Also shown are other embodiments in which the hooking assemblies are perpendicularly mounted below the rim device, as well as a flexible version with an inner and outer tube for changing the size of the aperture to meet the demands of differently sized basketball rims.

1 . A basketball rim attachment device for decreasing the diameter of the circular rim to increase shooting accuracy, comprising: 
 (a) an annular rim insertion device for insertion onto the circular rim; and    (b) a plurality of hooking apertures upon the annular rim insertion device for attachment to the rim in a manner that provides substantially rigid conformity with the rim when applied and removability when not applied.    
   
   
       2 . The device of  claim 1  comprised substantially of a plastic material.  
   
   
       3 . The device of  claim 1  comprised substantially of a polyvinyl material.  
   
   
       4 . The device of  claim 1  comprised substantially of a polyvinyl chloride material.  
   
   
       5 . The device of  claim 1  comprised substantially of a hard rubber.  
   
   
       6 . The device of  claim 1  comprised substantially of a metal material.  
   
   
       7 . The device of  claim 6 , wherein the metal is coated about a core of other material selected from the group consisting of plastics, polvinyls, polyurethanes, rubber, and metallic materials.  
   
   
       8 . The device of  claim 1 , wherein the hooking apertures are between 110 degrees and 270 degrees in cross-section.  
   
   
       9 . A basketball rim attachment device for decreasing the diameter of the circular rim to increase shooting accuracy, comprising: 
 (a) an annular rim insertion device for insertion onto the circular rim having a top and bottom surface wherein the bottom surface is relatively planar; and    (b) a plurality of hooking apertures having a planar top surface and a hooking assembly bottom surface, such that the top surface is disposed to the bottom surface of said rim insertion device upon the planar top surface of the apertures relatively perpendicular attachment thereto, wherein such hooking apertures are disposed at distances along the bottom surface of the rim to provide for rigid engagement with the rim via said hooking apertures.    
   
   
       10 . The device of  claim 9  comprising a material selected from the group consisting of plastic, polyvinyl, polyvinyl chloride, polyurethane, rubber, metallically coated materials, metals, and combinations thereof.  
   
   
       11 . A basketball rim attachment device for decreasing the diameter of a plurality of differing diameter circular rims to increase shooting accuracy, comprising: 
 (a) an annular rim insertion device for insertion onto the circular rim having a tubular structure comprising an outer tube and an inner tube such that the inner tube passes into said outer tube for frictional engagement;    (b) an engagement device for attaching said inner to said outer tube to fix the diameter of the device; and    (c) a plurality of hooking apertures disposed outwardly from said annular outer tube to engage the rim for flexible attachment and detachment thereto.    
   
   
       12 . The device of  claim 11  wherein said engagement device is a cotter pin, and said inner and outer tubes possess apertures for engagement therewith.  
   
   
       13 . The device of  claim 11  comprising a material selected from the group consisting of plastic, polyvinyl, polyvinyl chloride, polyurethane, rubber, metallically coated materials, metals, and combinations thereof.
