ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention is related to a basketball practice assembly and in particular to one which can be folded into a case on the wall when not in use.
2. Description of the Prior Art
The conventional basketball practice device generally includes a primary support for holding a backboard and a basket above the ground, a plurality of secondary supports configured to form a frame parallel to the primary support and standing on the ground, a plurality of telescopic links slidably mounted between the primary and secondary supports, and a net connected between the supports and having an open top, whereby the supports can be folded together when not in use. Nevertheless, the primary and secondary supports are arranged on the ground so that even if they are collapsed, the basketball practice device must still occupy a considerably large space on the ground thereby making it unfit for practical use.
Therefore, it is an object of the present invention to provide an improved basketball practice assembly which can obviate and mitigate the above-mentioned drawbacks.
SUMMARY OF THE INVENTION
This invention is related to an improved basketball practice assembly.
According to a preferred embodiment of the present invention, a basketball practice assembly a case including a box-like receptacle which is open at a front side thereof, and a pair of doors hingedly connected with two lateral sides of the box-like receptacle, a pair of fixing members fastened in the box-like receptacle by screws and having a vertical dovetail groove, a pair of telescopic arms each having two inner ends and two outer ends, one of the inner ends being fixedly engaged with the vertical dovetail groove, another one of the inner ends being sidably fitted in the vertical dovetail groove, a net arranged on the telescopic aims to form a rectangular member with an open top, a backboard installed in the receptacle, and a basket pivotally mounted on the backboard.
It is the primary object of the present invention to provide an improved basketball practice assembly which can be folded into a case when not in use.
It is another object of the present invention to provide an improved basketball practice assembly which will not occupy any space on the ground when not in use.
It is still another object of the present invention to provide an improved basketball practice assembly which can be easily extended for use.
It is still another object of the present invention to provide an improved basketball practice assembly which is simple in construction.
It is a further object of the present invention to provide an improved basketball practice assembly which is low in cost and easy to manufacture.
The foregoing objects and summary provide only a brief introduction to the present invention. To fully appreciate these and other objects of the present invention as well as the invention itself, all of which will become apparent to those skilled in the art, the following detailed description of the invention and the claims should be read in conjunction with the accompanying drawings. Throughout the specification and drawings identical reference numerals refer to identical or similar parts. Many other advantages and features of the present invention will become manifest to those versed in the art upon making reference to the detailed description and the accompanying sheets of drawings in which a preferred structural embodiment incorporating the principles of the present invention is shown by way of illustrative example.
