Detachable And Repeatedly Adhering Backboard

Abstract

A detachable and repeatedly adhering backboard, comprising a hoop, a swing article, a bridge board, a marking plate and a self-adhesive repeated patch, where the hoop joins the swing article, and the swing article is attached fixedly to the bridge board. By exploiting the characteristic of swinging back and forth of the swing article resulted from its self-elasticity nature, the hoop thus presents pliability which features eliminating vibration, absorbing effectively shock load, avoiding stress concentration which results in breaking of the hoop that hurts players and prolonging effectively the years of usage. With the aid of the self-adhesive repeated patch, the backboard is adhered directly to any desired surface to be fixed when using, which achieves the purpose of repeated use, free of the constraint by a mounting location.

What is claimed is: 
     
         1 . A detachable and repeatedly adhering backboard, comprising:
 a hoop, round in shape, joining a swing article at an end therein;   a bridge board, the swing article being attached fixedly to a front side therein by a fastening device;   a self-adhesive repeated patch, having repeated stickiness at a backside therein, and said bridge board being attached to a front side therein; and   a marking plate, being attached to a top portion of said bridge board by means of a linking device.   
     
     
         2 . The detachable and repeatedly adhering backboard as recited in  claim 1 , wherein said bridge board is provided with an elevated stand on the front side therein, and the elevated stand tapers off from its center toward all-around to form a plurality of tapered surfaces. 
     
     
         3 . The detachable and repeatedly adhering backboard as recited in  claim 1 , wherein the length and the width of said bridge board are not longer than 1.2 times of the diameter of said hoop. 
     
     
         4 . The detachable and repeatedly adhering backboard as recited in  claim 1 , wherein the fastening device is a rectangular-opening slot having a threaded hole at its bottom protruded part, both ends of the threaded hole corresponding to two position bars which are protruded from said bridge board, and two position holes disposed at the bottom of the position bars corresponding to the threaded hole, where two U-shaped springs are disposed between the two position holes and the threaded hole, and a position screw being used to penetrate orderly through the position bars and the slot to enable the slot to swing back and forth.
