Description
BACKGROUND OF THE INVENTION
[0001] The present invention relates to sports goals for use on
indoor or outdoor surfaces, and more particularly, to a portable
goal that is positional between a goal configuration and a compact
storage configuration.
[0002] U.S. Pat. No. 5,421,586 issued Amram et al. discloses a
portable sports goal having a frame that has a horizontal portion
providing a base that sits freely on an underlying playing surface
and an upright portion that defines a goal mouth. The goal includes
a goal net that is supported by the frame behind the goal mouth.
The goal mouth is defined by a pair of upright elongate goal posts
interconnected at upper ends by a crossbar. The base is provided by
a pair of elongate base bars extending rearward from lower ends of
the goal posts and a base rail interconnecting the ends of the base
bars opposite the goal posts. Elbow connectors interconnect the
above referenced elongate frame members forming a right angle at
each connection.
[0003] The above referenced goal is collapsible enabling it to be
readily carried and stored. As illustrated in FIG. 4 of the Amram
et al. patent, the frame is at least partially disassembled in a
knockdown condition thereby requiring reassembly when use of the
goal is desired.
[0004] U.S. Pat. No. 5,433,433 issued to Armell discloses a
so-called "pop-up" or "self-erecting" goal. Unlike the goal of
Amram et al., the Armell goal can be positioned in a collapsed
condition without disassembling the frame. As best illustrated in
FIGS. 4 and 5 of the Armell patent, the continuous spring steel
wire framework of the goal can be twisted and folded upon itself to
form two oval loops providing the goal in a substantially flat
storage position. A restraining means, or strap, is used to retain
the goal in the collapsed position. When the restraining strap is
removed, the tension in the wire framework causes the goal to
unfurl, or pop-up, into a goal configuration.
[0005] The above referenced goal of Armell requires an additional
retaining means or strap to maintain the wire framework in a
desired goal configuration. For example, see the strap illustrated
as reference numeral 20 in FIG. 1 of Armell that extends across the
goal mouth to maintain proper spacing between opposite sides of the
wire framework and to keep the goal upright.
[0006] Other sports goals are disclosed by U.S. Pat. No. 6,261,196
A1 of Caruso; U.S. Pat. No. 6,991,567 B2 issued to Wong et al.; and
U.S. Pat. Nos. 5,244,213 and D.384,382 issued to Armell. Also see
International Publication Nos. WO 2006/044389 A1 and WO 2006/044388
A2 of Szaro et al..
[0007] Although the above referenced sports goal disclosed in the
above referenced patents and publications may be satisfactory for
their intended purposes, there remains a need for a portable sport
goal that can be readily positioned in a goal configuration as well
as a compact, easy to carry, collapsed storage configuration.
Preferably, the goal should not require disassembly of the goal
frame to position the goal in the storage configuration and should
be easy to erect in a minimum of time with a minimum of effort. In
addition, preferably the goal, as erected, should not require a
strap or like support structure extending across or adjacent the
goal mouth to maintain the framework of the goal in a desired goal
configuration.
BRIEF SUMMARY OF THE INVENTION
[0008] The present invention is a portable, self-erecting sports
goal having a frame sufficiently flexible to be re-positioned
between a goal configuration and a storage configuration without
requiring disassembly of the frame. The frame includes first and
second goal posts interconnected at upper ends thereof by a
crossbar, a first base bar extending rearward from a lower end of a
first goal post, a second base bar extending rearward from a lower
end of a second goal post, and a base rail interconnecting the ends
of the first and second base bars opposite the goal posts. In the
goal configuration, the base bars and base rail support the sports
goal on an underlying ground surface, and the goal posts and
crossbar cooperate to define a substantially rectangular goal mouth
extending upright from the underlying ground surface. In the
storage configuration, the frame is twisted and folded upon itself
into a substantially flat and compact position enabling the sports
goal to be readily carried and stored.
[0009] According to one contemplated embodiment of the present
invention, the goal posts and base bars overlap to form a
substantially V-shaped section and the crossbar and base rail
overlap to form an arcuate section when the goal is in the storage
configuration. This causes the goal to assume a substantially
segmental, or flat pie-shaped, configuration. In this
configuration, the frame is in a pre-tensioned condition enabling
an amount of energy required to position the frame in the storage
configuration to be used to permit the frame to resiliently
self-erect itself into a goal configuration automatically upon
release from the storage configuration.
[0010] According to some contemplated embodiments of the present
invention, the crossbar extends at substantially right angles from
the goal posts, the base rail extends at substantially right angles
from the base bars, and the base bars extend at substantially right
angles from the goal posts. Preferably, the goal posts, crossbar,
base bars and base rail of the frame retain the frame in the goal
configuration without the use of other retaining means, straps and
supports extending across or near the goal mouth or netting. In
addition, preferably the goal posts and base bars are of identical
lengths, the crossbar and base rail are of identical lengths, and
the length of the crossbar is greater than the length of the goal
post.
[0011] According to some contemplated embodiments of the present
invention, each of the goal posts, base bars, crossbar and base
rail is elongate and extends in a straight line path. A separate
corner connector is used to interconnect the various separate
elongate parts of the frame. Preferably, the connectors
interconnect the parts of the frame at substantially right angles.
Each and/or selected ones of the elongate posts, bars and rails of
the frame is rotatable about its longitudinal axis relative to the
connectors. This enables ready manipulation of the frame into and
out of the storage configuration.

DETAILED DESCRIPTION OF THE INVENTION
[0019] The present invention is a sports goal 10 that is portable,
lightweight, and can be positioned in a compact configuration for
ready carrying, transportation and storage. For example, the goal
can be used in connection with soccer games and/or training
activities on indoor as well as outdoor playing surfaces. The goal
can also be used in connection with other sports and training
activities that generally require a goal mouth extending from a
playing surface.
[0020] The sports goal 10 has a frame 12 that supports a goal net
14. As best illustrated in FIGS. 1 and 3, the goal 10 provides a
traditional substantially rectangular goal mouth configuration. For
example, the frame 12 includes a pair of upright goal posts, 16 and
18, interconnected at their upper ends by a crossbar 20 thereby
defining a substantially rectangular goal mouth "M". The goal
posts, 16 and 18, are supported in a generally upright position on
an underlying playing surface by a portion of the frame 12 that
defines a base 22. The base 22 includes a pair of base bars, 24 and
26, extending rearward from the lower ends of the goal posts, 16
and 18, and a base rail 28 interconnecting the ends of the base
bars, 24 and 26, opposite the goal posts, 16 and 18.
[0021] In the illustrated embodiments, each of the goal posts 16
and 18, base bars 24 and 26, crossbar 20, and base rail 28 is
provided as an elongate rod-like structure that follows a
straight-line path between its opposite ends. The rods can be solid
or hollow, can be made of metal, fiberglass, plastic, composite
materials, or the like, and can have a rubber, plastic or like
outer covering. The rods must be sufficiently sturdy to maintain a
goal configuration (see FIGS. 1 and 3) while being resiliently
flexible to enable the frame 12 to be positioned into a compact
storage configuration, discussed in greater detail below. In
addition, the frame 12 should be able to maintain itself in the
goal configuration (see FIGS. 1 and 3) without the use of other
supports, straps or the like to retain the goal in a desired
configuration. For example, the strap (reference numeral 20)
illustrated in FIG. 1 of U.S. Pat. No. 5,433,433 is not required by
the goal according to the present invention.
[0022] As best illustrated in FIG. 1 of the present application,
the goal posts 16 and 18, base bars 24 and 26, crossbar 20, and
base rail 28 of the illustrated embodiment are interconnected by a
series of separate corner connectors, 30, 32, 34, 36, 38 and 40,
also referred to as elbow or right angle connectors. The
connectors, 30, 32, 34, 36, 38 and 40, permit the various elongate
components of the frame 12 to be interconnected at substantially
right angles. In addition, the combination of the posts, bars, rail
and connectors provide the frame 12 with a substantially continuous
and endless structure.
[0023] As best illustrated in FIGS. 5 and 6 of the present
application, the ends of the rod-like posts, bars and rail of the
frame 12 are retained in sockets 42 of the connectors. Preferably,
the ends of the posts, bars and rail of the frame 12 include an
enlarged diameter end piece 44 receivable in the socket 42. These
end pieces 44 are locked within the sockets 42 by a fastener 46.
The fastener 46 has a hollow central opening enabling the rod-like
shafts of the posts, bars and rail of the frame 12 to be inserted
therethrough so that the fastener 46 is carried on the rod-like
shaft. In the illustrated embodiment, the fastener 46 has a
threaded end 48 extending from a head section 50. The fastener 46
is free to rotate on the rod-like shaft of the posts, bars and rail
of the frame 12 about a longitudinal axis "L" extending through the
rod-like shaft. This permits the threaded end 48 of the fastener 46
to be screwed into cooperating threads (not shown) on an interior
wall of the socket 42, thereby capturing end piece 44 within the
socket 42. This assembly also permits the posts, bars and rail of
the frame 12 to be rotatable relative to the connectors, 30, 32,
34, 36, 38 and 40, which enables the frame 12 to be readily twisted
into the storage configuration discussed below.
[0024] By way of example, and not be way of limitation, the height
"H" of the goal 10 can be about 30 inches and the width "W" can be
about 49 inches. Of course, the goal 10 can be made to other
dimensions, both smaller and larger. Preferably, the length "L1" of
each goal posts, 16 and 18, is equal to the length "L2" of each of
the base bars, 24 and 26. In addition, preferably the length "L3"
of the crossbar 20 is equal to the length "L4" of the base rail 28,
and the length "L3" of the crossbar 20 is greater then the length
"L1" of each goal post, 16 and 18. This ensures that the goal 10
can be neatly positioned into a storage configuration as will be
discussed in greater detail below.
[0025] According to one specific example of the present invention
to which the invention is not limited, the lengths "L3" and "L4" of
the crossbar 20 and base rail 28 are each equal to about the length
"L1" of the goal posts, 16 and 18, multiplied by (.pi./2), or 1.57.
For example, if each goal post and base bar has a length of about
30 inches, the cross bar and base rail would each have a length of
about 30(.pi./2), or about 47 inches. These dimensions enable the
goal 10 to assume a substantially pie-shaped storage configuration,
or in some cases, the shape of a quadrant of a circle.
[0026] Various alternatives to the above referenced frame structure
can be utilized. For example, the frame can be provided as one
continuous piece of wire framework or the like without the use of
connectors. Alternatively, the goal posts and crossbar can be
formed of one continuous piece of framework or the like and a
separate continuous piece of framework can be used to form the base
22 with only a pair of connectors used to join the ends of the base
22 to the ends of the goal posts. Further, the connectors can be
formed in various shapes and capture the ends of the elongate frame
components by various locking means which may permit or prevent
rotation of the elongate components relative to the corner
connectors.
[0027] The goal net 14 can be secured to the frame 12 via flexible
sleeves 52 slipped over the elongate components of the frame 12
during assembly thereof. Preferably, the netting 14 is supported in
a slack condition from the frame 12 to absorb the energy of a
soccer ball or the like. The netting 14 is not required to be taut
nor is it required to retain the frame 12 in a goal
configuration.
[0028] Turning to the collapsible aspect of the goal 10 of the
present invention, the frame 12 of the goal 10 is sufficiently
flexible to permit the goal 10 to be re-positioned from a goal
configuration, as shown in FIGS. 1 and 3, to a compact storage
configuration, as shown in FIGS. 2 and 4. For example, a user can
convert the goal 10 into the storage configuration by gripping the
connector 30 at the lower end of the goal post 16 in the left hand
and the connector 32 at the lower end of the goal post 18 in the
right hand and by rotating the right hand and connector 32
clockwise for about 180.degree.. This twisting motion of the frame
12 positions the goal post 16 in an overlapping position with the
opposite base bar 26 and the goal post 18 in an overlapping
position with the opposite base bar 24, thereby forming a V-shaped
section 54. See FIGS. 2 and 4. This manipulation of the frame 12
also results in the crossbar 20 being positioned in an overlapping
condition with the base rail 28.
[0029] In the illustrated embodiment, the angle "A" formed between
the legs of the V-shaped section 54 is about 90.degree. and, the
crossbar 20 and base rail 28 each have a length sufficiently
greater than that of the legs of the V-shaped section 54 so that
the crossbar 20 and base rail 28 flex into and from an arcuate
section 56. Accordingly, the posts, bars, and rail of the frame 12
essentially are converted into a compact, flat, pie-shaped form.
Should the length of the cross bar be about (.pi./2) times the
length of the goal post, the storage configuration is essentially
equivalent to the shape of a quadrant of a circle. As shown in FIG.
4, the netting 14 remains on the frame 12 in the storage
configuration. In this configuration, the goal 10 can be readily
carried in one hand with multiple like goals and can be stored in a
compact flat condition.
[0030] The frame 12 is retained in the flat pie-shaped storage
configuration by use of one or more fasteners 58. As an example,
the illustrated fasteners 58 are provided as strips of
hook-and-loop fasteners. Alternatively, the fasteners 58 can be
provided as clips, clasps, straps with buttons, buckles, or snaps,
or the like.
[0031] In positioning the goal 10 into the storage configuration,
the user exerts an amount of energy to twist the frame 12 into the
flat pie-shape. The frame 12, particularly the crossbar 20 and base
rail 28, are resiliently elastic in that the above referenced
energy is essentially stored therein and is used to enable the goal
12 to self-erect itself into the goal configuration upon release of
the frame 12 from the storage configuration. For instance, the
crossbar 20 and base rail 28 are resiliently flexible and exert a
force to return from the arcuate condition to a straight-line
condition. Accordingly, the user can merely disconnect the
fasteners 58 and permit the goal to unfurl, or "pop-up" into the
goal configuration. No assembly is required.
[0032] While a preferred sports goal has been described in detail,
various modifications, alterations, and changes may be made without
departing from the spirit and scope of the anchor, assembly, and
method according to the present invention as defined in the
appended claims.
