GOLF PRACTICE NET
BACKGROUND OF THE INVENTION
This invention relates generally to apparatus and methods that allow
a person to practice hitting or throwing a ball or the like in a confined
space without having the ball travel a large distance or hit other persons or
objects and cause injury or damage. Still more particularly, this invention
relates to a. net or the like for catching a golf ball that has been hit with
a
golf club and then returning the golf ball to its general location before it
was hit with the golf club.
SLT1~RVIARY OF THE INVENTION
The golf practice net according to the invention has several
advantages over the prior art. The invention catches the ball and returns it
to the golfer and requires no anchors to keep in the desired location. The
golf practice according to the invention net requires no assembly, is self-
standing, easily collapsible for storage or transit and can be used indoors or
outdoors.
A self-erecting portable net according to the invention has an
erected configuration for practicing golf or the like by stopping the flight
of a projectile such as a golf ball and returning it to a selected location
and
a folded configuration for storage or transport. The portable net comprises
an elastic frame that includes a first frame member and a second frame
member. The first frame member is arranged to have an upper frame portion
and a lower frame portion, the lower frame portion and the second frame
member cooperate to form a base that supports the portable net in a
generally upright orientation on a generally horizontal surface when the
portable net is in its erected configuration. The Iower frame portion has an
end that is spaced apart from the upper frame portion to form a front
portion of the base, and the second frame member has an end that is spaced
apart from the upper frame portion to form a rear portion of the base.

DESCRIPTION OF THE PREFERRED EMBODIMENT
Referring to FIG. 1, a golf practice net 10 comprises a frame I2 that
includes a pair of wire frame members 14 and 16. The wire frame members
14 and 16 are airanged to form a base I 1 and a net support 13. A fabric 18
is connected to the frame members 14 and 16. The fabric I8 includes a first
fabric section 20 that is arranged so that a golf ball 22 that has been
stricken with a golf club 24 will impinge upon the first fabric section 20.
The first fabric section 20 stops the flight of the golf ball 22, which then
rolls down to a second fabric section 26. The sect,nd fahri~ cP~tinn ~~ ;~
arranged to allow the golf ball 22 to roll back to near where the person 3 0
struck the golf ball 22 with the golf club 24.

CA 02220220 1997-11-04
WO 97/32633 PCT/US97/03368

The first fabric section 20 preferably is formed of netting or the like
and is arranged to absorb the impact of the golf ball 22, which may be
traveling at a velocity typical for a golf ball that has been stricken with a
golf club such as an iron or a driver. The first fabric section 20 absorbs the
y
impact so that the golf ball 24 has no appreciable recoil velocity after it
hits
the first fabric section 20.
The frame members I4 and 16 are formed of a flexible material that
has a memory for the erected configuration of FIGS. I-3. Steel spring wire
is a suitable material for forming the frame members 14 and I6. The ends of
the wire frame member 14 preferably are connected together by any
convenient means so that the frame member I4 is a continuous loop. The
ends of the frame member 16 preferably are also connected together to
form a continuous loop.
The frame member 14 has an upper portion 32 and a lflwer portion
IS 34. The upper frame portion 32 preferably is substantially upright when it
is in the erected position of FIGS. I-3. The upper section 32 of the frame
member I4 is a net support section that supports the first fabric section 20.
The second fabric section 26 is mounted to the lower portion 34. The first
fabric section 20 is shown to have a curved peripheral band 40. The outer
edge of the peripheral band 40 may include a continuous sleeve 44 formed
around the periphery of the first fabric section 20 with the upper section
32 of the frame member 14 passing through the sleeve 44.
The frame member 16 and the portion of the frame member 14 that
extends below the band 40 as shown in FIGS. I-3 cooperate to form the
base for the golf practice net I0. Therefore, the golf practice net 10
according to the invention includes the base, the net support and the ball
return section. '

The upper fabric section 20 preferably is formed generally either as a
half oval or a semicircle. The band 40 has a lower, substantially straight
portion 50 that separates the upper fabric section 20 and the lower fabric
section 26. The lower fabric section 26 has an upper end 52 connected to
the straight band portion 50 and a lower portion 54 that extends to the
generally horizontal surface 55, such the earth, upon which the golf
practice net 10 rests when in use. The straight band portion 50 is
preferably about a foot or two above the horizontal surface 55. The frame
member 14 preferably is formed such that the lower end 54 of the second
fabric section 26 is displaced a few feet laterally from the band 50.
Therefore, the second fabric section 26 preferably is inclined at a shallow
angle from the horizontal.
The lower fabric section 26 has upper ends 60 and 62 that are
mounted to the frame member 14 a few inches above the horizontal band
portion 50. The lower end 54 of the lower fabric section 26 is mounted to
the frame member 14 by any suitable means such as a sleeve 71 or by a
plurality of straps (not shown). The lower fabric section 26 may be under
tension and is preferably arranged to have a shape that directs the golf ball
22 back to the golfer 30. As illustrated, the arrangement of the upper ends
60 and 62 and the lower end 54 is such that the lower fabric section 26
has a substantially concave shape. After the golf ball 22 strikes the upper
fabric portion 20, it then rolls down to the lower fabric section 26. The
concave shape of the lower fabric section 26 directs the golf ball 22 in the
general direction of the golfer 30. Therefore, the lower portion of the frame
member 14 and the fabric 26 form a ball return section.
The frame member 16 has a substantially straight section 80 that
passes through a sleeve 82 in the straight band portion 50 and then
extends to the rear of the golf practice net 10. The frame member 16 has a
curved portion 84 that extends between the ends 86 and 88 of the straight
section 80_ A fabric band 90 has its ends 92 and 94 connected to the band

CA 02220220 1997-11-04
WO 97/32633 PCTILTS97/03368
-6-
50. The curved portion of the frame member 16 passes through a plurality
of loops 100 connected to the band 90. Alternatively, instead of the loops
100, the curved portion 80 of the frame member may pass through a sleeve
(not shown). ,
The ends of the band 50 are connected to the first frame member 14.
Therefore, near the ends of the band 50, the frame members I4 and I6 have
portions near the upper end of the second fabric section 26 that are spaced
apart by only a small distance. A pair of fabric webbings 102 and 104
extend between the first frame member 14 and the second frame member
ZO 16. Although the portions of the frame members 14 and 16 that are close
together are curved, the webbings 102 and 104 are approximately
triangular in shape. The height of the webbings I02 and I04 are such that
when the golf practice net IO is erected, the webbings are substantially
vertical and extend from the band 50 to a location near the ground. The
I5 frame section 16 is also preferably formed as a continuous loop of a
flexible
material that has a memory for the configuration illustrated in FIGS. 1-3
when the golf practice net is erected.
Refernng to FIGS. 1 and 3, the golf practice net 10 preferably
includes a pair of straps 110 and I12 that extend from upper portions I14
20 and 116 on the sleeve 44 to locations I18 and 120 on the fabric band 90
near the rear edge of the curved portion 84 of the frame member I6. The
straps I 10 and 112 preferably cross one another to make a generally "X"
configuration. The straps I~10 and l I2 may be formed of heavy twine, rope,
wire, etc.
25 The golf practice net 10 may be folded for storage as shown in FIGS. ~
6A-6E. Because of the memory of the frame members 14 and 16 for the
erected configuration, unless it is constrained, the spring forces in the
frame
members 14 and 16 will cause the golf practice net IO to spontaneously

CA 02220220 1997-11-04
WO 97/32633 PCTJUS97/03368
-7_
assume the erected configuration. Therefore, the golf practice net is self-
erecting if the frame is not constrained to some other configuration.
Refernng to FIG. 6A, the first step in folding the golf practice net 10
for storage is to pull the rear leg, comprising the frame member 16 toward
the lower portion 34 of the upper frame member 14 so that they are
substantially adjacent. Referring to FIGS. 6B and 6C, the upper portion 32
of the frame member 14 is then pulled downward so that it bends about its
central portion, which is near the straight portion of the frame member 16.
Referring to FIG. 6D, after the end of the frame member 16 and the upper
and lower edges of the frame member 14 are pulled close together, the sides
of the frame members are pulled together so that the golf practice net 10 is
shaped generally as "taco shell." Referring to FIG. 6E, the folding process
continues by twisting the frame members 14 and 16 to form a pair of loops
130 and i32, which may be then held close together and secured by a
strap 134 or the like as shown in FIG. 6F. The frame members 14 and 16
then are coiled up in a compact configuration suitable for storage or
transport.
