The present invention relates generally to the field of sports board apparatus and methods, and more specifically to sports board apparatus and methods for forming sports boards using roll-formed metal materials.
It is often necessary, be it for the purposes of the playing of various sports, for safety, or otherwise, to surround the perimeter of a sports surface (e.g., an ice surface, a sports field, a ring, and a court) with a sports board apparatus. For example, the sport of hockey requires boards, often with acrylic plastic sheets or another substantially transparent and durable material positioned thereabove. These boards and transparent sheets may preferably serve both to define the area on which the game is played, and to prevent any projectiles from leaving the surface and thus disrupting the game or injuring onlookers.
Of course, hockey and other sports and entertainment may involve body contact among the competitors and/or movement of players and sports equipment (e.g., pucks, balls, other projectiles, sticks, other sporting implements and means of conveyance) at considerable speeds—whether these sports are played wearing, for example, bare feet, shoes, ice skates, or inline skates. As such, in order to be effective for its intended purpose, a sports board apparatus must be capable of withstanding the impact of any sports equipment and competitors that may have occasion to collide heavily therewith. Such impacts may occur, for example, as the result of calculated body checking, equipment malfunction, and/or misfortune or a lack of skill in traversing the sports surface.
It is also very common for multi-purpose use to be made of sports surfaces. For example, the same sports surface that is used for hockey may periodically have the ice surface removed therefrom, so as to be capable of use for basketball, concerts, equestrian events, and/or various other events. Sometimes, multi-purpose uses of the sports surface may call for the disassembly of the sports board apparatus. For these and other reasons, it may be desirable to provide a sports board apparatus that is capable of being quickly and easily assembled and disassembled on a regular or as needed basis, without employing highly skilled workers, and/or without sacrificing the structural integrity of the sports board apparatus. In this regard, prior art sports board assemblies may have been woefully inadequate, and/or may possibly have resulted in serious injury to such workers, to the sporting competitors, and/or to the entertainment onlookers, amongst others.
In order to provide the necessary strength, many prior art sports board assemblies may have been constructed, at least in part, from very heavy metal materials. While such materials may be structurally sound, they may also be inappropriately unwieldy and/or cumbersome. Some conventional sports board assemblies may have included components constructed from extruded aluminum (which has the benefit of a high resistance to corrosion) and/or hot rolled structural steel. The use of these materials may have been prohibitively costly, whether due to (i) the inherent cost of such materials, (ii) the high amount of labor involved in (the possibly quite mechanical and/or manual) manufacturing processes which may heretofore have been used to construct the individual components of these prior art sports board assemblies from such materials, and/or (iii) other factors.
Notwithstanding that light gauge steel (alternately referred to herein as “LGS”) may have similar corrosion resistant properties to those exhibited by aluminum, LGS—which may include coiled stainless steel and the like—may not have been used previously as a main structural component of prior art sports board assemblies. This prior failure to successfully employ LGS, as a main structural component in a sports board apparatus, may have been due in part to the shortcomings of LGS when used in conventional component geometries, insofar as it may heretofore have been structurally too weak, in comparison to some of the thicker and heavier materials mentioned above.
In addition to its anti-corrosive properties, LGS has the further advantage of being highly formable, enabling construction of components having relatively complex shapes from LGS, through the use of a series of continuous roller dies. As such, the use of LGS in a sports board apparatus—though not previously successful—may afford a relatively high efficiency of manufacture (e.g., in terms of time and money) in comparison with components formed from prior art sports board materials, without requiring the use of exceedingly heavy and/or otherwise cumbersome components. Preferably, such use of LGS in a novel and inventive sports board apparatus (e.g., according to the present invention) would also avoid seriously sacrificing the structural integrity of the sports board apparatus.
It is thus an object of the present invention to provide a sports board apparatus comprising posts formed from C-shaped post channel members nested in clusters for strength.
It is another object of the present invention to provide posts which are joined together in a nested fashion.
It is yet another object of the present invention to provide first and second beams in spaced relation from one another so as to define an elongate beam opening therebetween, which might allow passage therethrough of poles for holding substantially transparent sheets of material (e.g., acrylic plastic sheets).
It is still another object of the present invention to provide components of a sports board apparatus in a configuration that substantially conceals and/or reduces the prominence of all sharp edges thereof, so as to prevent and/or reduce risk of injury.
It is also an object of this invention to obviate or mitigate at least one of the above mentioned disadvantages of the prior art.

In the mechanical fastening step, the first member (described in greater detail hereinabove) is securely attached to the second member (described in greater detail hereinabove) using a mechanical fastener 190 extending substantially therethrough. Each of the first member and the second member is preferably selected from the group that includes the post. channel members 60,80,100, the web members 152, and the beams 210,212, among others.
In the mechanical fastening step, each of the mechanical fasteners 190 preferably extends substantially through a respective one of the nested pairs 138 of the dimpled portions 130. This mechanical fastening is such that a substantial extent of each of the mechanical fasteners 190 is fully received within the aforesaid respective one of the nested pairs 138 of the dimpled portions 130.
Operatively, each of the web members 152 and each of the beams 210,212 extends substantially between and securely engages the at least two posts 50a,50b,50c. Each of the beam members operatively engages the at least two posts 50a,50b,50c substantially adjacent to the upper end portion 52 thereof. Each of the beams 210,212 and each of the web members 152 is operatively secures relative to the boards 32. Each of the posts 50 is operatively secured relative to the boards 32 and to the sports surface 30, such that the lower end portion 54 of each of the posts 50 is operatively positioned substantially adjacent to the sports surface 30.
As aforesaid, the sports board apparatus 40 includes posts 50a,50b,50c formed from C-shaped post channel members 60,80,100 which are advantageously nested in clusters, and thus provide strength. The posts, 50a,50c′ and 50a′,50c, are joined together in a nested fashion. The first and second beams 210,212 are provided, as aforesaid, in spaced relation from one another so as to define an elongate beam opening 214 therebetween, which allows passage therethrough of the poles 226 for securely holding the transparent planar sheet 224 (e.g., an acrylic plastic sheet). The configuration of the components of the sports board apparatus 40 according to the present invention in such as to substantially conceal and/or reduce the prominence of sharp edges thereon, so as to prevent and/or reduce risk of injury.
It should be additionally appreciated (i.e., from all of the foregoing, from the claims, and from the drawings) that the use of LGS in the sports board apparatus 40 according to the invention provides significant anti-corrosive properties. The use of LGS according to the present invention provides a highly formable material and enables construction of components having relatively complex shapes from LGS, through the use of a series of continuous roller dies. As such, the components of the sports board apparatus 40 according to the present invention allow for a relatively high efficiency of manufacture (e.g., in terms of both time and money) over components formed from prior art sports board materials. The present invention does not require the use of exceedingly heavy and/or otherwise cumbersome components, without seriously sacrificing the structural integrity of the sports board apparatus 40.
Other modifications and alterations may be used in the design and manufacture of other embodiments according to the present invention without departing from the spirit and scope of the invention, which is limited only by the accompanying claims.
