1. Field of the Invention
The present invention relates to goal posts used on sport fields, in particular the invention related to improved lightweight, portable, low cost goal posts.
2. Description of Prior Art
Rugby Football is becoming more popular in the United States and other countries. However, with a few notable exceptions such as Stanford, U.C. Berkeley and West Point there are few permanent Rugby Football Stadiums. Fields used for Rugby are typically used for soccer, baseball and other sports that require the Rugby goal posts to be removed after the match or tournament is concluded. Further, Rugby typically is a club sport and the clubs have limited resources and need to play in different fields.
For many years, Rugby Football has been played all over the world. However, the sport has been more popular in countries other than the United States, making Rugby Football fields scarce. American Football and Association Football (soccer) fields, on the other hand, are everywhere. Having the ability to erect a low cost, portable Rugby goal post would make it easier to play Rugby on any suitable pitch.
In the case of Rugby Union, the International Rugby Board (IRB) sets the specification for the size and shape of the regulation Rugby goal posts. Currently the goal post must be at least 3.4 meters high with the cross bar being 3.0 meters high and 5.6 meters wide (between the upright posts).
Previously, single piece goal posts have been manufactured of rectangular or round (tubular) metal. However, these are heavy, expensive, and difficult to transport. Some versions have a removable cross bar, but are still difficult to transport because they don't fit in a passenger vehicle and are relatively difficult to breakdown and reassemble.
What is needed is a lightweight, low cost, portable Rugby goal post that can be broken down, placed inside commonly available vans and SUVs and reassembled.
SUMMARY OF THE INVENTIONIt is an objective of the present invention to provide an improved goal post having various advantages that make for quick and easy setup and ultimately facilitate the playing of Rugby on any suitably sized sports field. The various embodiments include novel, lightweight, strong, low cost manufacture, easy to setup, easy to store, easy to transport goal posts.

In the drawings, closely related figures have the same number but different alphabetic suffixes.
Testing showed that this PVC-only goal post met some of the requirements but was not a complete solution. PVC pipe is relative flexible. As illustrated by
To meet regulation size while using standard connectors, the upper posts 3, lower posts 5 and cross bar sections 6 are cut to different lengths, for example some are cut to nine feet while the others are cut to nine feet ten inches. This difference in size makes it difficult to quickly assemble the pipes in the right configuration.
In one embodiment, the PVC pipes were cut from six 2″ by 20′ PVC pipes and assembled with 2″ Tees, Cap, Connectors.
PVC Pipes with Wooden Reinforcements
The T connectors with screw entry 20a and 20b are connected onto the upper posts 3a and 3b, the lower posts 5a and 5b forming the posts 9a and 9b. The cross bar sections 6a and 6b are connected into the T connector with screw entry 20a and 20b respectively and into the straight connector 12 forming the cross bar 8. The center horizontal board 36 is placed inside the straight connector 12 prior to it being connected to cross bar sections 6a and 6b.
The screw 26 and washer 28 are inserted through the connector screw entry 34 of the T connector with screw entry 20, into the vertical board screw hole 30 and threaded into horizontal board screw hole 32 to hold the vertical board 22 and the horizontal board 24 together. The outer PVC pipes are reinforced by the inner boards.
In one embodiment, the board are made from 2″×2″×2″ redwood cut into one 5′ and one 3′ length, respectively.
Testing showed good results as far as the shape of the goal posts, but there are still problems.
The screw 26 joint into the horizontal board 24 at the horizontal board screw hole 32 is weak and doesn't hold up over a few uses. Alternative embodiments attempt to improve this by using bolts that attach to nuts embedded in the horizontal board 24, or use different hardware, but these embodiments still have the following problems in common with the previous disclosure.
Because the details of the complex reinforcement mechanism is hidden, in testing the wooden boards (22, 24) were innocently broken by volunteers helping to take this wood reinforced goal post down.
There are many parts and it is difficult to assemble and requires special tools such as wrenches, pliers, and screwdrivers. It's hard to keep track of the tools while carrying the PVC pipes and parts from the vehicle and across the fields. The screw is difficult to put in place and easy to lose on the playing field. Once lost, a large screw presents a hazard for injury.
The assembled poles 9a and 9b and the crossbar 8 have irregular shapes because the T connectors 20 and straight connector 12 have circumferences larger than the PVC pipes (for example see outline of
Portable Goal Post with Single Piece Reinforcements
This assembly requires no tools. For each goal post, in a pair of goal posts, there are only three components (1a, 1b, and 2) needed to connect the pipes. The parts are easy to carry, hard to lose, hard to break. The pieces are intuitive and easy to assemble and disassemble.
In an embodiment where the pipes (3a, 3b, 5a, 5b, 6a, and 6b) are cut to the same length, the length of the respective bodies (69 and 79) are made so that the regardless of which pipe is used, the resulting goal post 11 will be regulation size and shape.
Once assembled, the goal post 11 is held up, for example, by placing the lower posts 5a and 5b over standard steel fence posts 7a and 7b that are driven into the ground.
In one embodiment the tops of the upper posts 3a and 3b are left open.
In yet other embodiments the tops of the upper posts 3a and 3b are closed with caps 4a and 4b (
The assembled goal post 11 is lightweight, has a smooth outer consistent diameter, and performs well despite the substantially lower cost of PVC pipe. The goal post 11 can be assembled and disassembled without tools or loose parts. The assembly and disassembly is intuitive and is simpler and faster. The disassembled goal post 11 can fit in most passenger vehicles including station wagons and sedans with fold out seats.
Embodiments of Single Piece ReinforcementsDetails of one embodiment of molded pieces are shown in
Good results have been obtained where each of the legs are greater than two feet in length. The legs reinforce the respective pipes providing greater structural strength and help maintain the desired goal post shape enabling the use of low cost, lightweight, relatively flexible materials for the pipes, such as for example two inch PVC pipe.
As discussed above, optionally, when the T body 69 and cross bar body 79 have sufficient predetermined length the pipes (3a, 3b, 5a, 5b, 6a, & 6b) can have identical lengths simplifying assembly and transport.
The invention may be manufactured as a product comprising molded T reinforcements 1 and a cross bar reinforcement 2. Only the single piece reinforcements (1, 2) need to be manufactured and shipped. The caps (4 or 80) could also be included. The user can then obtain the standard PVC pipe (cut to size) and fence posts at a local hardware store. This reduces manufacturing, warehousing and shipping costs, but provides an easy to use, durable, reusable, portable solution.
