Detachable And Repeatedly Adhering Backboard
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.
The present invention generally relates to backboards, and more particularly to a backboard capable of being detachable and repeatedly adhering.
DESCRIPTION OF THE PRIOR ARTBasketball is an athletic sport through cooperation among team members to shot the basketball into the opposite team's hoop. To be one of the popular recreations as well as physical exercises, the basketball has been widely accepted by the civilians, schools, and the internationals The existing hoop structures are made up mostly of a hoop and an L-shaped rigid frame connected to one end of the hoop, where the frame is further attached fixedly on a backboard or a wall. Since the frame is a rigid body without featuring shock absorption through swinging back and forth, it tends easily to stress concentration at the welding spot between the hoop and the frame, subject to a violent slam dunk. And the frame is easy to be fractured as a result of longtime use, which for sure hurts players. Moreover, the direct screw connection of the frame to the backboard or the wall makes the hoop structure fail to dismount and mount somewhere else at will, which couldn't meet the demand of players that call for flexible use.
SUMMARY OF THE INVENTIONThe objective of the present invention is to overcome the drawbacks of the aforesaid conventional technique by providing a pliable hoop, capable of eliminating vibration and absorbing shock load; and a detachable and repeatedly adhering backboard, capable of being detachable at will and adhering to any desired surface to be fixed at will.
In order to achieve the above objectives, an object of the present invention is to provide with a detachable and repeatedly adhering backboard, especially 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 at its one end, and the swing article is attached fixedly to the bridge board by means of a fastening device. The bridge board is affixed with a self-adhesive repeated patch on its backside, and the marking plate joins the bridge board firmly by means of a linking device.
Another object of the present invention is to provide with a detachable and repeatedly adhering backboard, especially for the hoop that connects to the swing article at its one end, and the swing article is attached fixedly to the bridge board by means of a fastening device. 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.
A further object of the present invention is to provide with a detachable and repeatedly adhering backboard, which means that the bridge board is affixed with a self-adhesive repeated patch on its backside. Adhering directly to any desired surface to be fixed when using, the backboard achieves the purpose of repeated use, free of the constraint by a mounting location.
A still further object of the present invention is to provide with a detachable and repeatedly adhering backboard, which further means that the bridge board is provided with an elevated stand on its front side, and the elevated stand tapers off from its center toward all-around to form plural tapered surfaces. By tearing down the self-adhesive repeated patch upward, the self-adhesive repeated patch caters to the greater curvature formed from the edges to the center, which enables the sticky substance to form an angle with respect to the attached surface that makes the patch to be stripped gradually and won't destroy the attached surface.
A still further object of the present invention is to provide with a detachable and repeatedly adhering backboard, which further means that the length and the width of the bridge board are not longer than 1.2 times of the diameter of the hoop. Since the actual supporting strength is at the center of the bridge board, the curved-surface stress of smaller area is larger than that of the bigger area for the bridge board as long as they are in same thickness. Therefore, the bridge board contracts in size to support the shaking movement of the swing, and further to enhance the ability of absorbing the shock load.
A still further object of the present invention is to provide with a detachable and repeatedly adhering backboard, which further means that the fastening device is a swayable slot having a threaded hole at its bottom part, where the threaded hole corresponds to two position holes at its both sides respectively which are disposed at two position bars, and the position bars are protruded from the surface of the bridge board. Two U-shaped springs are clamped by the two position holes and fixed by a screw penetrated through them and the threaded hole, with which the swinging back and forth of the slot can be achieved, and the deformation of an L-shaped swing article can be declined.
