The present invention pertains to sports game goalposts and, more particularly, to a goalpost with adjustable spacing of uprights, with adjustable height, and with adjustable verticality thereof.
Football is a game in which two opposing teams of 11 players each defend goals at opposite ends of a field having goalposts at each end, with points being scored chiefly by carrying the ball across the opponent's goal line and by place-kicking or drop-kicking the ball over the crossbar between the opponent's goalposts. The football goalposts typically consist of a vertical support member inserted into the ground of the field, with the vertical member transitioning into a horizontal support member, with this portion of the goalpost called a gooseneck. A crossbar is attached at its midpoint to the end of the horizontal portion of the gooseneck, and at each end of the crossbar are attached a horizontal upright member. Field goals and extra points are scored in football by kicking the ball between the two uprights, and over the crossbar.
It is important for the goalpost to fulfill the specification of the football league in which the goalpost will be used. These specifications include definition of the size of the goalpost, including height and width, and also the alignment of the goalpost uprights relative to the geometry of the playing field. The geometry includes the height of the crossbar, the width of the space between the uprights of the goalpost, and the verticality of the uprights relative to the perpendicular football field plane.
A problem arises when the same playing field is to be used by different leagues. This is commonly the case when there is a high school league game using the same field on which college games are played. Because a typical high school league uses an upright width of 23 feet and 4 inches, while typical college leagues use an upright width of 18 feet and 6 inches, goalposts which uprights have the appropriate width must be used. A convenient solution is here presented by the present invention in which goalposts with adjustable spacing of the uprights is provided. As a result, a single goalpost assembly can be changed from one configuration to another, easily and simply.
Another problem has to do with the ability to adjust the upright verticality, the angle relative to the perpendicular football field plane, after the sleeve supporting the crossbar has been installed in the ground. The present invention has a built-in capability to adjust the uprights vertically by rotating them about the horizontal axis at the connection with the crossbar.
Three prior art patents address uprights with a variety of width modifications, and height and vertical angular correction (i.e., verticality). U.S. Pat. No. 6,394,917, issued to CHIAPPINI, et al., on May 28, 2002, for Goal Posts with Adjustable Components, describes an assembly using a linear actuator, either a rack and pinion system, a pneumatic system, or a hydraulic system to provide a translation mechanism along the crossbar for the adjustment of the width between the two uprights. In addition, CHIAPPINI describes an assembly for adjusting the height, and side-to-side tilt, as well as front-to-back tilt of the supporting gooseneck member. This mechanism is a complex assemblage of a substantial number of parts, and the complexity of the design increases the costs of production and the cost of maintenance, as well as the weight of the entire goalpost structure. The present invention of adaptable uprights uses fewer than half as many parts. Much simpler, more robust and lighter than the prior art, the present invention's manual mechanism is less expensive to manufacture, easier to transport, easier to assemble, and easier to maintain.
U.S. Pat. No. 6,375,585, issued to DRISCOLL, on Apr. 23, 2002, for Adjustable Goalpost Assembly describes a translation mechanism along the crossbar in which each upright is mounted on a trolley and each upright can slide along the crossbar. This prior art does not allow adjusting the upright verticality after insertion of the supporting sleeve in the ground. More over, in regard to the capacity to ensure the stability of the uprights in their non-inclinable vertical position, the trolley used in this prior art is a less robust and heavier mechanism than the present invention.
U.S. Pat. No. 5,429,350, issued to MEIER, on Jul. 4, 1995, for Goal Post Inserts, describes a goalpost assembly with three cylindrical solid inserts for added strength of the goalpost. This invention provides reinforcement for withstanding the stress of victorious fans climbing the goalpost. The described invention does not provide for any adjustment of the spacing of the uprights.
Another concern is about the current existence of two types of playing field: real turf and artificial turf. These two types of playing field have a one and one half inch difference in height. Existing football goalposts require preliminary work on the goalpost prior to delivery to the playing field for assembly, preparing the goalpost assembly for use with either real turf or artificial turf. The present invention permits the mechanical components that constitute the uninstalled goalpost to be assembled on a job site without preceding preparation, for either natural or artificial turf, with necessary adjustments to accommodate the type of turf made at the assembly site.
In view of the foregoing, an objective of the present invention is to provide football goalposts with adjustable spacing of uprights, to accommodate the requirements of different football leagues.
Another objective of the present invention is to provide goalposts with the verticality of the uprights adjustable by rotation of the connections between the uprights and the crossbar.
Another objective of the present invention is to provide goalposts with adjustable width of the uprights, robust enough to ensure the stability of the uprights in the specified verticality.
Another objective the present invention is to provide goalposts with adjustable uprights, using a simpler, lighter, and less expensive apparatus compared to prior art.
Another objective of the present invention is to provide goalposts with a sleeve inserted in the ground, into which the bottom of the gooseneck is inserted, with an optional riser, which permits the on-site installation of a single version of the assembly with adjustment of height for use with either real turf, or artificial turf.
Another objective of the present invention is to provide goalposts with a sleeve inserted in the ground, into which the bottom of the gooseneck is inserted, wherein the diameter of the sleeve is sufficiently larger than the diameter of the inserted gooseneck, such that the gooseneck's verticality may be adjusted front-to-back and side-to-side, by adjustment of the connection of the top of the sleeve to the gooseneck.
A complete understanding of the present invention may be obtained by reference to the accompanying drawings, when considered in conjunction with the subsequent detailed description, in which:
a is a front view of the entire goalpost structure, as installed on artificial turf;
b is a perspective view of the sleeve that is placed in a hole in the field;
c is a perspective exploded view of the sleeve, the riser, and the bottom of the gooseneck;
a is the perspective view of the gooseneck mount as welded on the crossbar;
b is the perspective view of the gooseneck mount as an individual part, before attachment to the crossbar;
For purposes of brevity and clarity, like components and elements of the apparatus of this invention bear the same designations or numbering throughout the FIGURES.
This invention provides goalposts that provide adjustable width of the uprights. This invention provides goalposts that provide the ability to adjust the level of the crossbar, i.e., horizontal angularity, by rotation around the gooseneck to crossbar connection. This invention additionally provides goalposts with adjustable verticality of the uprights by rotation around the horizontal axis of the crossbar. This invention also provides a riser that may be used on the bottom of the gooseneck portion of the goalpost permitting the same assembly to be used either for football played on natural turf or artificial turf, where a height adjustment of one and one half inches is required. This invention also provides an adjustment of the gooseneck verticality by tilting side-to-side and front-to-back, within the sleeve that is inserted into the hole in the field.
The entire goalpost is an assembly of tubes, preferably constructed of aluminum, providing light weight and strength. In the embodiment shown in
