Basketball System with Capability of Repetitive Installation

Abstract

A basketball system comprises a backboard, a first rectangular plate, a second rectangular plate, and a resilient sticking sheet. The backboard is provided with a basketball hoop at its front surface. The first rectangular plate is provided with a tab and placed adjacent to a top edge of the backboard. The second rectangular plate is fastened to a back surface of the backboard and pivotally connected with the first rectangular plate. The resilient sticking sheet, being always with a predetermined level of adhesion, is attached to a back surface of the first rectangular plate and defines a plurality of recesses at its back surface, so that the first rectangular plate can be attached to a supportive surface with the vacuum existed between the sticking sheet and the supportive surface. With the system, the backboard can be repetitively installed on various supportive surfaces at different sites without destruction of the surfaces.

I claim: 
     
         1 . A basketball system, comprises:
 a backboard provided with a basketball hoop at a front surface thereof;   a first rectangular plate provided with a tab at one side thereof and placed adjacent to a top edge of the backboard;   a second rectangular plate, corresponding to the first rectangular plate, fastened to a back surface of the backboard and pivotally connected with the first rectangular plate along the top edge of the backboard; and   a resilient sticking sheet attached to a back surface of the first rectangular plate and defining a plurality of recesses at its back surface, the resilient sticking sheet being always with a predetermined level of adhesion, so that the first rectangular plate can be attached to a supportive surface with the vacuum existed between the resilient sticking sheet and the supportive surface;   whereby the backboard can be easily and repetitively installed on various supportive surfaces at different sites without destruction of the surfaces.   
     
     
         2 . The basketball system of  claim 1 , wherein the sticking sheet is replaced by a resilient sticking sheet without recesses. 
     
     
         3 . The basketball system of  claim 1 , wherein the first rectangular plate can be moved down to lie on the second rectangular plate for protecting the resilient sticking sheet thereon, when the system is not in use. 
     
     
         4 . The basketball system of  claim 1 , wherein the back surface of the resilient sticking sheet is further provided with an always sticky layer for enhancing adhesion capability. 
     
     
         5 . The basketball system of  claim 1 , wherein the resilient sticking sheet is replaced by a resilient flat sheet without recesses, wherein the resilient flat sheet is provided with an integral sticky layer at its back surface and a strong adhesive layer at its back surface, wherein the integral sticky layer can be attached to the supportive surface, whereas the strong adhesive layer can be attached to the back surface of the first rectangular plate.
