- Referring to
FIGS. 1-3 , the foldable goal frame according to an embodiment of the present invention includes: abase 1, vertical bars (goal posts) 2, and atop bar 3. Thebase 1 includes: afirst support bar 10, asecond support bar 11 disposed in parallel to thefirst support bar 10 in the deployed state, and athird support bar 12 that is joined at its one end to the first end of thefirst support bar 10 and at its other end to the first end of thesecond support bar 11. Thefirst support bar 10 and thethird support bar 12 are joined together by afirst folding joint 40, and thesecond support bar 11 and thethird support bar 12 are joined together by asecond folding joint 41. The pivotal axes of the first and secondfoldable joints - The
vertical bars 2 includes a firstvertical bar 20 and a secondvertical bar 21. The lower end of the firstvertical bar 20 and the second end of the of thefirst support bar 10 are joined together by athird folding joint 42, and the lower end of the secondvertical bar 21 and the second end of the of thesecond support bar 11 are joined together by afourth folding joint 43. The pivotal axes of the third and firstfoldable joints 42 and 40 (both joints being connected to the first support bar 10) are perpendicular to each other. Similarly, the pivotal axes of the fourth and secondfoldable joints - One end of the
top bar 3 and the upper end of the firstvertical bar 20 are joined together by a fifth foldingjoint 44, and the other end of thetop bar 3 and the upper end of the secondvertical bar 21 are joined together by asixth folding joint 45. The pivotal axes of the fifth and thirdfoldable joints 44 and 42 (both joints being connected to the first vertical bar 20) are perpendicular to each other. Similarly, the pivotal axes of the sixth and fourthfoldable joints foldable joints - In a preferred embodiment, the
top bar 3 includes three (or more) telescoping tubes. More specifically, the middle tube of thebar 3 has a smaller diameter than, and can slide into, the two end tubes of the bar; or alternatively, the middle tube of thebar 3 has a larger diameter than, and can slide over, the two end tubes of the bar. A releasable locking structure is provided at the connection locations of the tubes to keep them in the extended configuration. For example, the releasable locking structure may include a spring loaded ball or pin provide on one tube with a corresponding through hole provided on the connected tube, where the ball or pin can protrude through the through hole when the two tubes are in the extended state or other predefined relative positions. Alternatively, releasable locking structure may include one or more through holes provided on each tube, and a pin that passes through the through holes. The through holes on different tubes will be aligned with each other when the two tubes are in the extended state or other predefined relative positions to allow the pin to pass through them. Other suitable releasable locking structures may be employed. Further, the connecting ends of the tubes may have non-round cross-sectional shapes that can prevent the tubes from rotating relative to each other, which can make it easier to assemble the releasable locking structure. Thethird support bar 12 has a similar telescoping structure as thetop bar 3. The telescoping structures of thetop bar 3 and thethird support bar 12 also allow the user to adjust the width of the goal, and can help to reduce the folded size of the goal frame as described in more detail later. - A first inclined support bar 5 is disposed between the first
vertical bar 20 and thefirst support bar 10. A second inclined support bar 6 is disposed between the secondvertical bar 21 and thesecond support bar 11. The first inclined support bar 5 includes aupper section 50 with its upper end pivotally connected to a point along the firstvertical bar 20, and alower section 51 with its lower end pivotally connected to a point along thefirst support bar 10. Theupper section 50 andlower section 51 of the first inclined support bar are joined together by aseventh folding joint 46. In preferred embodiments, the first inclined support bar 5 is not located on the plane defined by thefirst support bar 10 and firstvertical bar 20; rather, it is located on the outside side or the inside side of that plane (with respect to a center of the goal frame). The rotation axes of the pivotal connections of the first inclined support bar 5 to thefirst support bar 10 and firstvertical bar 20, as well as the pivotal axis of the seventhfoldable joint 46, are parallel to the pivotal axis of the thirdfoldable joint 42 that joins thefirst support bar 10 and the firstvertical bar 20. The second inclined support bar 6 includes aupper section 60 and alower section 61 joined together by aneighth folding joint 47. The second inclined support bar 6 is connected to the secondvertical bar 21 and thesecond support bar 11 in a similar manner that the first inclined support bar 5 is connected to thebars - In this embodiment, the first to eighth folding joints 40-47 have identical or similar structures. Each folding joint pivotally joins two bars, with the pivotal axis perpendicular to the two bars, so that the two bars can pivot toward or away from each other. Preferably, the pivotal joint does not allow rotation of the bars around their longitudinal directions, which ensures stability of the goal frame. The folding joint allows the two bars to be pivoted to a state where they are disposed parallel to and adjacent each other, preferably without any appreciable gap in between. In the illustrated embodiment (see
FIG. 3 ), each folding joint includes a first connectingmember 400 and a second connectingmember 401 respectively connected to the two bars that are being joined, a shaft (not visible inFIG. 3 ) passing through them to act as the pivotal axis, and a hand-operable turn knob 402 (a locking member) at the end of the shaft. The first and second connectingmembers locking member 402 cooperate with each other to press the first and second connectingmembers member 400 and/or the second connectingmember 401, and the turn knob is formed integrally with the shaft and can turn the shaft to press the two connecting members against each other. In another embodiment, the shaft is threadedly engaged with internal threads of theturn knob 402, and cooperate with the turn knob to press the first connectingmember 400 and second connectingmember 401 against each other. The faces of the first connectingmember 400 and second connectingmember 401 that contact each other may be provided with radially extending teeth which help prevent the two connecting members from rotating relative to each other after they are pressed tightly against each other. This enhances the stability and safety of the goal frame after deployment. - In an alternative embodiment, the first connecting
member 400 and second connectingmember 401 may have through holes at off-axis locations, where the through holes are aligned with each other when the bars being joined are rotated to desired relative positions (e.g. to achieve the deployed state), and a pin may be inserted through the aligned through holes to lock the relative rotation of the bars. In other alternative embodiments, the folding joints may user other structures such as hinges, in which case the two bars are connected to the hinge by bolts. More generally, any suitable structure may be used to pivotally join the two bars together with a releasable locking structure. When unlocked, the folding joint allows the two bars to pivot relative to each other, and when locked, the folding joint prevents the two bars to pivot relative to each other. The releasable locking structure is preferably hand-operable, but may also use a structure (such as bolts and nuts) that requires a tool to operate. - When folding the goal frame, first, the third folding joint 42 and fourth folding joint 43 are unlocked so they can pivot; the first
vertical bar 20, the secondvertical bar 21, along with thetop bar 3, as a whole, are folded toward the direction of thebase 1. During this folding step, the upper and lower sections of the first inclined support bar 5 and second inclined support bar 6 are also folded around the seventh folding joint 46 and eighth folding joint 47, respectively. After this first folding step, the firstvertical bar 20 and thefirst support bar 10 are disposed in parallel and adjacent to each other, the secondvertical bar 21 andsecond support bar 11 are disposed in parallel and adjacent to each other, and thetop bar 3 and thethird support bar 12 are disposed in parallel and adjacent to each other. Note that this requires the firstvertical bar 20 andfirst support bar 10 to have the same lengths, and the secondvertical bar 21 andsecond support bar 11 to have the same lengths. Theupper section 50 andlower section 51 of the first inclined support bar 5 are also disposed in parallel and adjacent to each other, and they are disposed in parallel and respectively adjacent to the firstvertical bar 20 andfirst support bar 10. Theupper section 60 andlower section 61 of the second inclined support bar 6 are disposed adjacent to the secondvertical bar 21 andsecond support bar 11 in a similar manner. - Next, the first folding joint 40, the second folding joint 41, the fifth folding joint 44 and the sixth folding joint 45 are unlocked; the first
vertical bar 20 andfirst support bar 10 are folded toward thetop bar 3 and thethird support bar 12, and the secondvertical bar 21 andsecond support bar 11 are also folded toward thetop bar 3 and thethird support bar 12. After the second folding step, both the firstvertical bar 20 and secondvertical bar 21 are disposed in parallel and adjacent to thetop bar 3, and both thefirst support bar 10 andsecond support bar 11 are disposed in parallel and immediately adjacent to the third support bar 12 (seeFIG. 2 ). In this folded state, all bars are parallel to each other, and preferably without any appreciable gap between adjacent bars. - Preferably, the sum of the lengths of the first and second
vertical bars top bar 3, so a gap may exist between the firstvertical bar 20 and secondvertical bar 21 after the second folding step. The lengths of thefirst support bar 10, thesecond support bar 11 and thethird support bar 12 have a similar relationship. Thus, thetop bar 3 and thethird support bar 12 can be shortened, e.g. by retracting the telescoping sections of these bars into each other. Preferably, the shortened lengths of the top bar 3 (and the third support bar 12) is approximately equal to the total length of the firstvertical bar 20 and the secondvertical bar 21. Note that the step of shortening thetop bar 3 and thethird support bar 12 may be performed before the first and/or second folding steps. - In an alternative embodiment, in the second folding step, the first
vertical bar 20 and thefirst support bar 10 are folded toward one side of thetop bar 3 and thethird support bar 12, and the secondvertical bar 21 and thesecond support bar 11 are folded toward the opposite side of thetop bar 3 and thethird support bar 12, so thebars bars bars top bar 3 and thethird support bar 12 to be shortened to an even shorter length, e.g., approximately the length of theindividual bars - A goal frame according to embodiments the present invention has a simple structure, which allows a user to deploy the goal frame by unfolding it. The user is not required to assemble the goal frame. Moreover, by providing folding joints at key positions of the goal frame, the folded goal frame is a compact bundle of parallel bars. This reduces the packaged size for transportation and enhances efficiency.
- It will be apparent to those skilled in the art that various modification and variations can be made in the goal frame and related folding method of the present invention without departing from the spirit or scope of the invention. Thus, it is intended that the present invention cover modifications and variations that come within the scope of the appended claims and their equivalents.
