Tennis teaching shade

Abstract

Provided herein is a shading device useful in conjunction with wheeled carts which are used by tennis instructors to train students. A shading device according to the invention is adapted to be retrofitted to existing tennis ball storage carts. Use of the present invention provides a tennis ball storage cart having a shaded area external to the left or the right side of the cart, where an instructor may stand, shaded from the sun while serving balls to a student or otherwise observing court activity. By use of the invention, an instructor may spend many hours instructing students on sunlit days without being effected by the harmful effects of the sunlight.

I claim:  
     
         1 ) A device useful for shading a cart which comprises: 
 a) a first generally U-shaped member which defines a first plane;    b) a second generally U-shaped canopy-supporting member which defines a second plane;    c) means for securing said first member and said second member together, said means for securing being configured so that said first member, second member and means for securing all reside only within the first plane or the second plane, and wherein a single angle is defined by the intersection of said first plane and said second plane.    
     
     
         2 ) A device according to  claim 1  further comprising: 
 d) a canopy disposed about said second member.  
 
     
     
         3 ) A device according to  claim 1  in which said angle is any angle in the range of 45 degrees to 120 degrees.  
     
     
         4 ) A device according to  claim 1  in which said angle is any angle in the range of 60 degrees to 100 degrees.  
     
     
         5 ) A device according to  claim 1  in which said angle is about 80 degrees.  
     
     
         6 ) A device according to  claim 1  in which said means for securing said first member and said second member together is slidably engageable with at least one of said first member or said second member.  
     
     
         7 ) A device according to  claim 1  wherein the frame members are all of a single construction.  
     
     
         8 ) A device according to  claim 1  in which only the second generally U-shaped member is slidably engageable with the means for securing, and the first generally U-shaped member and securing means are of a single construction.  
     
     
         9 ) A device according to  claim 1  in which only the first generally U-shaped member is slidably engageable with the means for securing, and the second generally U-shaped member and securing means are of a single construction.  
     
     
         10 ) A device according to  claim 1  in which said canopy comprises a material selected from the group consisting of: wood, plastic sheet, metal sheet, screens, canvas, vinyl sheet, cotton, linen, and PVC.  
     
     
         11 ) A wheeled cart useful as a teaching aid for tennis instruction which comprises: 
 I) a storage compartment configured in a generally rectangular solid configuration comprising: 
 i) a front wall portion having an inner surface and an outer surface;  
 ii) a rear wall portion having an inner surface and an outer surface, and having an upper portion and a lower portion;  
 iii) a left side wall portion having an inner surface and an outer surface;  
 iv) a right side wall portion having an inner surface and an outer surface;  
 v) a floor portion;  
 vi) an open top portion;  
 vii) a handle means disposed at said upper portion of said rear wall portion; and  
   II) a shading means which comprises: 
 a) a first generally U-shaped member which defines a first plane;  
 b) a second generally U-shaped canopy-supporting member which defines a second plane;  
 c) means for securing said first member and said second member together, said means for securing being configured so that said first member, second member and means for securing all reside only within the first plane or the second plane, and wherein a single angle is defined by the intersection of said first plane and said second plane,  
   wherein said first member is attached to said storage compartment at a location selected from the group consisting of: the right side wall portion or the left side wall portion; and 
 d) a canopy disposed about said second member, so as to provide a shaded region to an area external to the storage compartment in a location selected from the group consisting of: the right side of said cart or the left side of said cart.  
   
     
     
         12 ) A wheeled cart according to  claim 11  in which said angle is any angle in the range of 45 degrees to 120 degrees.  
     
     
         13 ) A wheeled cart according to  claim 11  in which said angle is any angle in the range of 60 degrees to 100 degrees.  
     
     
         14 ) A wheeled cart according to  claim 11  in which said angle is about 80 degrees.  
     
     
         15 ) A device according to  claim 11  in which said means for securing said first member and said second member together is slidably engageable with at least one of said first member or said second member.  
     
     
         16 ) A device according to  claim 11  wherein the frame members are all of a single construction.  
     
     
         17 ) A device according to  claim 11  in which only the second generally U-shaped member is slidably engageable with the means for securing, and the first generally U-shaped member and securing means are of a single construction.  
     
     
         18 ) A device according to  claim 11  in which only the first generally U-shaped member is slidably engageable with the means for securing, and the second generally U-shaped member and securing means are of a single construction.  
     
     
         19 ) A device according to  claim 11  in which said canopy comprises a material selected from the group consisting of: wood, plastic sheet, metal sheet, screens, canvas, vinyl sheet, cotton, linen, and PVC.
