Abstract

Low cost, durable, reusable, lightweight, inexpensive, simple, easy to assemble/disassemble, transportable goal posts. The goal posts may be composed of single piece T reinforcement and single piece cross bar reinforcements, as well as readily available construction materials, such as PVC pipe. The bodies of the single piece reinforcements are sized so that the pipes forming the upright posts and crossbar have the same length. Assembly, disassembly, and transportation are simplified. The disassembled components can be carried in vans and SUVs. Internal reinforcements allow flexible, low cost materials such as PVC pipe to be used while maintaining a professional, aesthetic appearance.

Description

BACKGROUND

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 INVENTION

It 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.

DESCRIPTION OF THE INVENTION

PVC Pipes and Connectors Solution

FIG. 1 illustrates an early attempt to solve the above described problems was to make portable goal posts out of commercially available PVC pipes and standard connectors (FIG. 1). T connectors 10 a and 10 b are connected onto upper posts 3 a and 3 b, lower posts 5 a and 5 b forming posts 9 a and 9 b. Cross bar sections 6 a and 6 b are connected into the T connectors 10 a and 10 b respectively and into a straight connector 12 forming a cross bar 8.
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 FIG. 2, the weight of the cross bar 8 caused cross bar 8 to sag and the posts 9 a and 9 b to lean inward. This PVC-only solution could be challenged because did not meet regulation shape and brought ridicule to the home team.
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
FIGS. 3 and 4 illustrate how the PVC-only solution was improved by using wooden reinforcements inside the cross bar and inside the T connections.
FIG. 3 illustrates the details of the wooden reinforcement comprising vertical board 22 and horizontal board 24. A screw 26 is inserted through washer 28 into a vertical board screw hole 30 and tightened to hold the vertical board 22 and the horizontal board 24 together. In order to attach the board together inside the PVC pipes, the standard T connector is replaced with a T connector with screw entry 20, which has a connector screw entry 34, which allows access to insert the screw 26, and a wrench (not shown).
FIG. 4 illustrates a reinforced PVC pipe goal post. The vertical boards 22 a and 22 b, the horizontal boards 24 a and 24 b and the center horizontal board 36 are placed inside PVC posts (3 a, 3 b, 5 a, 5 b, 6 a and 6 b) and T connector with screw entries (20 a and 20 b). After the boards are inside the PVC components, the PVC pipes are inserted into the connectors. Optionally, a center horizontal board 36 is also placed inside the PVC cross bar sections (6 a and 6 b) and straight connector 12 to further reduce the sag in the cross bar 8.
The T connectors with screw entry 20 a and 20 b are connected onto the upper posts 3 a and 3 b, the lower posts 5 a and 5 b forming the posts 9 a and 9 b. The cross bar sections 6 a and 6 b are connected into the T connector with screw entry 20 a and 20 b 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 6 a and 6 b.
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 9 a and 9 b 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 FIG. 2).
Portable Goal Post with Single Piece Reinforcements
FIG. 5 shows goal post 11, which uses single piece reinforcements (1, 2) that are made of lightweight but strong material such as plastic or metal. The single piece reinforcements are preferably manufactured through a molding process, but some embodiments may be homemade using commercially available materials. In one embodiment the pipes are standard PVC pipes cut to the same length. The pipes including the upper posts 3 a and 3 b, lower posts 5 a and 5 b, and cross bar sections 6 a and 6 b are connected onto the T reinforcements 1 a and 1 b. The upper posts 3 a and 3 b are connected onto legs 60 a (of 1 a and 1 b respectively), and the lower posts 5 a and 5 b are connected onto legs 60 c (of 1 a and 1 b respectively), forming the posts 9 a and 9 b. The cross bar section 6 a is connected onto leg 60 b of T reinforcements 1 a and the cross bar leg 70 a of the cross bar reinforcement 2, and the cross bar section 6 b is connected onto leg 60 b of T reinforcements la cross bar leg 70 b of the cross bar reinforcement 2 forming the cross bar 8.
This assembly requires no tools. For each goal post, in a pair of goal posts, there are only three components (1 a, 1 b, 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 (3 a, 3 b, 5 a, 5 b, 6 a, and 6 b) 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 5 a and 5 b over standard steel fence posts 7 a and 7 b that are driven into the ground.
In one embodiment the tops of the upper posts 3 a and 3 b are left open.
In yet other embodiments the tops of the upper posts 3 a and 3 b are closed with caps 4 a and 4 b (FIG. 8A) or with caps with wind streamer attachments 80 (FIG. 8B), respectively.
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 Reinforcements

Details of one embodiment of molded pieces are shown in FIG. 6, namely the T reinforcement 1, and in FIG. 7A, namely the cross bar reinforcement 2. The body of each T body 69 and cross bar reinforcement body 79 preferably has the same outer diameter as the PVC pipes including the upper posts 3 a and 3 b, lower posts 5 a and 5 b and cross bar sections 6 a and 6 b. The reinforcement legs 60(a-c) and cross bar legs 70(a-b) have an outer diameter that fits tightly the inner diameter of the PVC pipes (3 a, 3 b, 5 a, 5 b, 6 a, & 6 b). The T body 69 and the cross bar reinforcement body 79 leg shoulders 63(a-e) that match the end of each PVC pipe (3 a, 3 b, 5 a, 5 b, 6 a, & 6 b) when fully inserted (forming a hidden seam) providing the consistent outer diameter for the goal post 11.
FIG. 6 illustrates one embodiment of the T reinforcement 1, comprising a T body 69 and three legs (60 a, 60 b, and 60 c). Where the respective legs connect to the T body 69, the T reinforcement 1 comprises a leg shoulder (63 a, 63 b, and 63 c, respectively).
FIG. 7A illustrates one embodiment of the cross bar reinforcement 2, comprising a cross bar body 79 and two cross bar legs (70 a, and 70 b). Where the respective legs connect to the cross bar body 79, the cross bar reinforcement 2 comprises a leg shoulder (63 d and 63 e, respectively).
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 (3 a, 3 b, 5 a, 5 b, 6 a, & 6 b) can have identical lengths simplifying assembly and transport.
FIG. 7A through 7E show various embodiments where the legs are formed in alternate ways. Each shows an embodiment of a leg connected at the leg shoulder 63 as shown FIG. 6 (to the T body 69) or FIG. 7A (to the cross bar body 79). These leg embodiments are exemplary and not intended to be restrictive of the invention. These embodiments are lightweight and strong.
FIG. 7A illustrates leg reinforcement 66(a-e) consisting of a cylinder with cross hair with horizontal and vertical reinforcements. This embodiment provides the best reinforcement for the respective pipes, but has more material and cost.
FIG. 7B illustrates a first alternate leg 71 consisting of a vertical bar with thin disks set at intervals. This embodiment helps maintain the round shape of the pipes with less material than the embodiment in 7A. This embodiment provides good linear support in one dimension, as is primarily needed with the cross bar 8.
FIG. 7C illustrates a second alternate leg 72 consisting of intersecting bars with thin disks set at intervals. This embodiment helps maintain the round shape of the pipes with less material than the embodiment in 7A. This embodiment provides good linear support in two dimensions.
FIG. 7D illustrates a third alternate leg 73 consisting of a vertical bar with circle cutouts 75 hole. This embodiment reduces the material and cost over the other embodiments shown.
FIG. 7E illustrates a fourth alternate leg 74 comprising vertical and horizontal pieces having a cross hair cross-section.
FIGS. 7A and 7E are examples of embodiments that could be home made. The bodies could be made by cutting PVC pipe and sheets of PVC plastic to form the shapes shown and then melding them into a single piece using PVC cement. The PVC pipe and PVC cement are available at local hardware stores. PVC plastic sheets can be obtained cut to size, from plastic stores or the Internet, e.g. Tap Plastics, www.tapplastics.com.

Caps

FIG. 8A shows an embodiment of the cap 4 with the cap shoulder 84 for the present invention. FIG. 8B shows the embodiment of a cap with wind streamer attachment 80 for the present invention. As with the embodiment of cap 4, the cap with wind streamer attachment 80 also has a cap shoulder 84 making both interchangeable. In addition, a provision for a wind streamer 81 is made and is held by a wind streamer attachment 82. The wind streamer attachment 82 is made via a hole in the cap 80 or via a hole in an eye loop molded into the cap 80.

Minimal Shipping

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.
