Description
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates generally to portable basketball
goals, and more specifically to a miniature portable and adjustable
basketball goal designed for safe and easy use by small children,
and which is economical to construct and can be firmly anchored in
place.
2. Description of the Prior Art
Since the invention of the game of basketball there have been many
goal constructions proposed, and several of these have been
designed to be portable so that they can be placed on and removed
from any suitable playing surface. However, none of the portable
goals that have been proposed and which are available commercially
give adequate consideration to the special demands of at home use
by small children from age 3 to about age 10.
To be practical for home use, the average family must be able to
easily afford the purchase of the portable goal. Presently
available portable goals are generally too expensive for the
average wage earner to purchase, mainly because of complex design.
Accordingly, there is need for a portable goal that is of
economical design, a need which the present invention meets.
A portable goal of necessity requires a base and standard
arrangement for supporting the hoop.
When dealing with goals for use by larger children and adults, the
design of the supporting structure is not too important. However,
where a portable goal is to be used by small children, special
problems are involved, because of the inexpertness with which such
children normally handle the ball and their frequent inability to
avoid colliding with stationary objects while playing.
Presently available portable goals usually have supporting
structures that include exposed structural members of small
diameter or width. These members can cause severe injury to a child
colliding therewith, and a loose ball can easily become entangled
therewith. Further, a misdirected thrown ball striking such a small
member frequently bounces back in a most erratic and unpredictable
fashion, an event which causes difficulty in recovery for a small
child. The present invention is especially designed with the small
child in mind, and minimizes these problems.
A portable goal for home use must also be easy to move and simple
to anchor in place. The present invention satisfies both of these
demands.
SUMMARY OF THE INVENTION
The present goal includes a base made of angle irons, to which is
attached a flat front wall facing the playing area, and two flat
side walls that extend rearwardly from the front wall. These three
flat surfaces effectively shield the angle iron members both from a
small child in the playing area, and from a misdirected playing
ball.
Specifically, because only flat surfaces are presented to the
playing area physical injury to a child colliding with the base
will be minimized. Should a ball strike the flat surfaces it will
merely bounce forwardly thereoff, in a predictable manner. Thus,
the base is uniquely suited for use by children age 3 and up.
The angle iron base supports a vertical standard, made simply from
two sections of pipe joined by a collar, the lower pipe section
being welded to the angle irons of the base. This is a most
economical arrangement, and disassembly of the upper pipe section
for storage purposes is a simple matter. Because only the vertical
standard itself projects above the front base wall, and all of the
supporting angle irons are shielded by the three walls, a clean and
attractive structure especially suited for use by small children
results.
A hoop is mounted conventionally on a plywood blackboard, and the
latter is adjustably secured to the upper pipe section by a pair of
clamps. Thus, the height of the hoop is easily adjusted to
correspond to the ages of the children using the goal.
The goal can be easily and quickly placed on any suitable playing
surface. When installed on a hard surface, such as a driveway or a
basement floor, concrete blocks or the like are placed on a
platform carried by the base for securing the goal in place. Four
stakes are utilized to secure the base in place on a lawn, the
three flat walls serving to shield both the concrete blocks and the
stakes from the playing area. With the anchor blocks and stakes
removed, the goal is light in weight and can be easily carried.
The present goal, since it is for use by small children, is, of
course, smaller than the standard goal. The design features of the
invention are especially adaptable to such a miniature goal.
It is the principle object of the present invention to provide a
portable and adjustable basketball goal that is economical to
construct, easily adjustable to various heights, and substantially
nontipable when in place for play.
Another object is to provide a miniature basketball goal for use by
small children, designed to present only flat wall-like surfaces to
the playing area.
Other objects and many of the attendant advantages of the invention
will become readily apparent from the following Description of the
Preferred Embodiment, when taken in conjunction with the
accompanying drawing.

DESCRIPTION OF THE PREFERRED EMBODIMENT
Referring now to the drawings, the goal of the invention is
indicated at 2 and includes a base 4, a vertical standard 6 mounted
on the base, a backboard 8, and a hoop 10 secured to the backboard
8 by bolts 12.
The base 4 includes a rectangular frame 5 formed of a front angle
iron 14, a rear angle iron 16, and side angle irons 18, the ends of
said angle irons being welded together to form a rectangle, with
the vertical flange of each member being to the outside. The
vertical standard 6 is comprised of upper and lower pipe sections
20 and 22, respectively, detachably joined together by a threaded
collar 24. The bottom end of the lower pipe section 22 rests
centrally on and is welded to the horizontal flange 26 of the front
frame angle iron 14.
The vertical standard 6 is braced to the frame 5 against lateral
movement by a pair of front braces 28, each of which is made of
strap steel and comprises a vertical portion 30 and an upwardly
inclined portion 32, joined by a rounded corner portion 34. The
bottom end of each front brace 28 is welded to the end face of the
vertical flange 36 and the horizontal flange 26 of the front angle
iron 14, so that the front edge of said brace is flush with the
outer surface of the vertical flange 36. The lower pipe section 22
is set back from the front face of the vertical flange 36 a
distance corresponding to the width of the front braces 28, and the
upper ends of said braces extend to the center of and are welded to
said lower pipe section.
The front braces 28 are braced by side braces 38 made of strap
steel, each side brace 38 including a vertical portion 40 welded at
its lower end to the rear frame angle iron 16, and a horizontal
portion 42 that extends forwardly to the associated front brace 28
and is welded thereto just below the corner portion 34. Finally,
stability for the vertical standard 6 is assured by a diagonal,
inverted channel-shaped brace member 44 that is welded at its lower
end centrally to the vertical flange of the angle iron 16, and at
its upper end to the pipe section 22 behind the upper ends of the
front braces 28. The standard 6 is thus firmly anchored to the base
frame 5 against movement in any direction.
Welded to the edges of the front brace members 28 and to the
vertical flange 36 of the angle iron 14 is a steel sheet front wall
46, the wall 46 having inclined upper edges 48 that mate with the
inclined brace portions 32. Similarly, steel sheet side walls 50
are welded to the side braces 38 and the vertical legs 30 of the
front braces 28, the vertical legs 40 of the side braces 38
projecting beyond the ends of the rear angle iron 16 a distance
corresponding to the thickness of the brace members 38 whereby the
side walls 50 are in contact with the entire length of the side
braces 38 and the height of the brace portions 30. The front wall
46 and the side walls 50 thus completely shield the brace members
28, 38 and 44, as well as the base frame 5, from the playing area
in front of the goal. Only flat surfaces are presented to a child
using the goal, which as discussed hereinabove will minimize the
danger of physical injury and make easy the recovery of a ball
fumbled in front of the goal.
The walls 46 and 50 also, of course, add stability to the base 4 by
reinforcing the braces 28 and 38.
The backboard 8 can be of plywood or some other suitable material,
and is secured to the vertical standard 6 by a pair of vertically
aligned clamp members 52. Each clamp member 52 includes a
semi-cylindrical portion 54 for embracing the upper pipe section
20, and a pair of flat securing wings 56 that are secured to the
backboard 8 by bolts 58. Obviously, by merely loosening the bolts
58 the backboard 8, and hence the hoop 10, can be adjusted to any
height.
A pair of plates 60 of plywood or the like is received within the
base frame 5, the outer corners of the plates having rectangular
cutouts 62 therein. The plates 60 are also cut-out at 63 to fit
about the pipe section 22.
The bottom horizontal flanges of the angle irons comprising the
frame 5 have holes 64 in the four corners of said frame beneath the
cutouts 62, which serve to receive anchor stakes 66. The anchor
stakes 66, as shown in FIGS. 7 and 8, are utilized to secure the
goal 2 in place on a lawn or directly on the earth. Each stake 66
is L-shaped and includes a head portion 68, the plate cutouts 62
being sufficiently large to easily accommodate said head portions
68.
The goal 2 is light in weight and is easily moved about. The four
stakes 66 will normally anchor it firmly to the earth, but if
further anchoring is desired, concrete blocks 70 (FIG. 4) or like
weights can be stacked on the plates 60. Any such weights 70 are
shielded by the front and side base walls 46 and 50, and thus they
cause no safety hazard and the neat appearance of the goal 2 is
preserved.
When utilizing the goal 2 on a driveway, a basement floor, or other
hard surface, the stakes 66 are not employed. Instead, the weights
70 alone are utilized to anchor the goal. The upper end of the
standard 6 has holes 72 therein, to which brace wires can be
attached if necessary.
As has been mentioned, the dimensions of the goal 2 are smaller
than for a standard goal. Typically, the standard 6 will have an
overall height of about 8 feet, and the goal hoop 10 can thus be
positioned at nearly any desired height from about 6 feet
downwardly. For small children, the hoop 10 should be about 14
inches in diameter, and a ball of about 7 inches in diameter should
be used for playing.
Obviously, many modifications and variations of the invention as
shown and described are possible.
