Patented July 3, 1945 PORTABLE BASKETBALL GoAni a 1 Gerald A. Gibson, xcel or, Minn. Application Jur 9, 194s,-s 'ria1n0. 493,991; 2 Claims. (01. 248-192;)
This invention relates to goals for ball games, and more particularly to portable goals for use in the practice and play of the game of basket ball.
Portable basket ball goals of various types have been devised heretofore. They have the disadvantage, however, of being unstable after a' short period of use since the construction of the supporting'standards have been such that the frequent blows of the ball against the backboard have worn different portions of the unit with'the result that the basket and backboard soon tilt at an angle. Not only is this true but the goals are generally improperly balanced and are Furthermore, in the past it has been the tendency to either substitute a basket of entirely the wrong shape without a backboard, or if correct backboard and basket were used to use the latter without any semblance of balance. These past arrangements have prevented the player from using fundamentals of basketball since he had the choice of shooting at either an unstable basket or a basket entirely different from the one used in standard play.
It is a general object of my invention to provide an ofiicially approved portable basket ball goal which is stable inconstruction and which can be readily adjusted in height to meet the physical capacity of the players to properly direct their shots to the basket with a basket ball meeting ofiicial standards.
Another object of the invention is to provide a stable yet portable basket ball goal which can be readily dismantled for convenient movement.
Another object of the invention is to provide a portable basket ball goal including a support wherein the backboard can be easily replaced in the event the original board is damaged due to exposure out of doors.
A more specific object of the invention is to provide a portable basket ball goal including a base and upright, wherein the upright is formed of two telescoping sections which are vertically adjustable relative to each other and wherein the upper section includes an integral unit for supporting the backboard and the basket.
These an other objects and advantages of the invention will more fully appear from the following description made in connection with the accompanying drawing, wherein like reference characters refer to the same parts throughout the views, and, in which:
Fig. 1 is a front elevation thereof;
Fig. 2 is a side elevation thereof;
' Fig.3 is an enlargedvertical section showing portions of the supporting'postthe' backboard,
and the basket brackets; and- Fig. 4 .is an enlarged section taken approxi mately on the line 4-4 of Fig. 1.
In Figsl andZ there is illustrated a circular, concavo-con'vex' base The convex'side of the base'is uppermost and presents a gently rounded surface which hasn'o projections which might cause 'injury'toth'eplayers. .Across the bottom of the base is locateda spider 6' which is provided at its center with a threaded socket'l. The upper central portion of the base 5 hasan' aperture' 8 formed therein; and-the lower edge of the base has a shockreducing rim 9 of rubber or other yielding material positioned thereon.
' Extending upwardlyfrom-the base 5 is an upright or vertical post A. This post is formed of a lower tubular section II] and an upper section II which telescopes into said lower section Ill. The lower post section I0 is provided with threads. I2 at its bottom end, these threads being adapted to fit into the threaded socket 1 at the center of the spider 6 in the lower portion of the base 5. At the point where the lower post section III emerges from the base 5 there is a split collar I3 which isv preferably secured to the base 5 by any suitable means such as bolts I4 which are disposed-in spaced relation to the split ends I5 so that the collar I3 is rigidly secured to the base 5 and is also releasably secured to the lower post section II] by reason of the nutted take-up bolts I6.
The upper post section II,.as has been stated before, telescopes into the lower post section I0.
Said upper post section II can be vertically adjusted relative to the lower post section I0, and the adjusted position of said upper section II is controlled by a spring pressed pin I1 which is I secured to the outer lower section I0 and is adapted to be positioned in registering apertures in the two post sections, as best indicated in Fig. 3. The pin I1 serves as a vertical support for the upper post section .II but it does not provide lateral support therefor. For thisreason, there is provided a locking bolt I8 which extends freely through an aperture I9in the lower post section I0 and which can be threaded into any one of a plurality of threaded apertures. 20 in the upper post section II. When the bolt I8 is tightened the two post sections I0 and II can be drawn together laterally to prevent any relative tilting of one post section to the other.
The backboard 2| is secured to the top portion of the upper post section II. Extending upwardly from the top central portion of the post section H is a relatively broad fiat plate-like brace 22. This is adapted to fit into a socket 23 which is formed upwardly from the lower central edge of the backboard 2i. Extending outwardly from each edge of the plate-like brace 22 is an arm 24 of channel shape in cross section and each of said arms 24 extends along the bottom edge and up the side edges of the backboard 2i and said arms 24 are connected to the backboard 21 by suitable means such as screws 25.
Also extending upwardly from the top of the upper supporting post section II is a pair of brackets 25 which extend vertically and thence outwardly horizontally in opposite directions. The brackets 26 are also connected to the backboard 2! by means of nutted bolts 21 which clamp said brackets 26 and the backboard 2| together as a stable unit. The brackets 25 are adapted to support conventional baskets 28, the upper basket rim 29 being secured to the horizontally extending portions of the brackets 26 and the downwardly diagonal basket braces 30 being connected by any suitable means to the lower vertical portions of said brackets 26.
From the foregoing description it will be seen that I have provided a portable basket ball goal which is sturdy in construction and which can be easily dismantled for movement to various temporary locations such as fromindoors to outdoors. It is provided with a relatively wide spread base whose width is approximately that of the widest spread of the backboard as well as the extreme distances between opposite edges of the baskets, and at the same time the base affords no dangerous obstruction to players running in close to the baskets. The connections between the base and the upright support or post unit assure maintenance of the post unit in a rigid vertical position regardless of the strenuous use to which the goal is put.
As stated above, the post unit A telescopes vertically and means is provided to insure rigidity where the two sections are connected together. Additionally, the upper post section H includes as a unit the plate 22 extending upwardly into the backboard 2|, the arms 24 which are secured to the edge of the backboard, and the brackets 26 which comprise the supports for the baskets 28. The result of this construction is a readily portable, yet extremely rigid goal post for basket ball which can be made to meet all the requirements of standardized athletic practice, but can also be adjusted for juniorrequirements.
It will, of course, be understood that various changes may be made in the details, arrangement, form, and proportions of the various parts without departing from the scope of my invention.
What I claim is:
1. In a game ball standard, a base having a lower portion with a socket therein and an upper portion spaced above said lower portion with an aperture therein, a vertically disposed post passing through said aperture and extending into said socket, and releasable clamping means rigidly secured to said base adjacent said aperture and positioned to engage said post adjacent said aperture.
2. In a basket ball goal, a. central base, a vertical post extending upwardly from said base, and a post tightening ring rigidly secured to said base and releasably embracing said post.
