DETAILED DESCRIPTION OF THE INVENTION

(5) Reference is made herein to the attached drawings. Like reference numerals are used throughout the drawings to depict like or similar elements of the hockey puck system of the present invention. For the purposes of presenting a brief and clear description of the present invention, the preferred embodiment will be discussed as used for determining whether the hockey puck has crossed the threshold of the hockey goal and illuminating a light source when the event has occurred. The figures are intended for representative purposes only and should not be considered to be limiting in any respect.

(6) Referring now to FIG. 1, there is shown a schematic view of the hockey puck 50 of the present invention. The hockey puck 50 is one that includes an RF receiver 57 that receives radio signals emitted from an energized wire installed along the threshold of the hockey goal. The RF receiver is a small radio receiver or an RFID tag that receives a specific radio frequency signal that the goal system emits. The threshold of the hockey goal includes an energized wire, wherein the relative location of the hockey puck can be registered by the hockey puck circuit by way of signal strength. When a given threshold is met and the calibrated signal is registered by the puck circuit 56, an illumination source 55 is energized to alert those involved of a scored goal. Generally the calibrated signal will be one in which the signal strength received by the RF receiver 57 reaches its zenith, whereby at this signal strength the puck 50 has passed completely over the goal line and into the hockey goal interior.

(7) The RF receiver is part of an analog circuit 56 that includes a battery power source 58 and a light source 55. These elements are imbedded within the puck interior and do not change its shape or weight. The light source 55 projects through the upper and lower surfaces or the sides of the puck such that it is visible to a camera and to the naked eye when illuminated. The receiver 57 and associated circuitry 56 are adapted to receive a specific frequency signal emitted from the hockey goal system, which is emitted from a perimeter wire around the threshold of the goal. The circuit 56 registers the signal strength thereof and is calibrated to realize when the signal strength registers its peak and when this correlates to the position of the puck being over the goal line. Once the light source 55 is energized, it remains energized for a period of time, whereby a timer circuit controls its illumination. This prevents the light source from flashing for too short of a period, and allows the light source 55 to reset after a goal is scored without external controls.

(8) Referring to FIGS. 2 and 3, there is shown an illustrative example of the hockey goal system of the present invention and the energized wire 110 disposed within the structure of the goal and across its threshold. Hockey goals generally include a frame comprising a pair of upright goal posts 101, a crossbar member 102, and rear frame members comprising an upper frame member 106, a lower frame member 104 and rear upright member 105. The goal posts 101 and the crossbar member 102 form the threshold of the goal, while the rear frame members support the goal netting 103 away from the threshold to provide an open goal interior. The style and sophistication of hockey goals varies with respect to the local rules and the type of environment in which the goal is used. Most hockey goals used for professional level competition also include a movable camera within the goal to visually track the puck and to view shots from a perspective within the goal interior.

(9) The system of the present invention comprises an elongated wire 110 that is energized by a transmitter 115. The transmitter is a powered assembly that energizes the wire 110 such that the wire emits a specific frequency radio signal therefrom. The wire 110 is disposed within the interior of the goal along its threshold, whereby the wire 110 forms a closed loop around the perimeter of the goal opening. Specifically, the wire 110 is extends in a loop that starts at the transmitter 115 location and terminates at the transmitter 115 location after forming a loop about the threshold of the goal. The wire 110 is routed through the cross bar member 102, down the goal posts 101 and across the threshold of the goal along the ground surface and between the two goal posts 101. The wire then extends through the opposing goal post 101, through the cross bar member 102 and into the transmitter assembly 115once again.

(10) The exposed wire is very thin gauged and is adapted to be positioned flushly against the ground surface or embedded therein. Its position relative to the goal line is inward within the goal with respect thereto, such that the signal strength registered by the hockey puck is created at the moment the entire puck has passed over the goal line and the hockey puck can be considered a goal. The hockey goal frame is substantially hollow, therefore the wire can be suspended therein via guides 111, which positioned the wire in a taught configuration through the interior of the goal frame and prevent grounding against any metal components therein. The guides 111 also facilitate the wire positioning centrally within the hollow interior of the frame at bends and at the exit of the wire along the goal line.

(11) Referring specifically to FIG. 3, there is shown a perspective view of the hockey goal of the present invention and an illustrative view of the operation of the system. The hockey puck 50 comprises a standard ice hockey puck shape, or alternatively a rounded hockey ball shape, wherein the puck includes an internal RF receiver that can register the signal strength of the RF signal being emitted from the imbedded wire 110 in the hockey goal. When the signal strength reaches a predefined maximum, the puck 50 recognizes that it has passed over the threshold of the goal and the puck registers a goal. Upon registering a goal, a light source within the puck 50 illuminates, wherein the illumination is visible through the sides 51 of the puck or along the upper 60 or lower 61 surfaces thereof.

(12) The position of the wire 110 along the threshold of the goal is important for the system to be properly functioning and such that the exposed wire does not interfere with the natural motion of the puck during gameplay. The position thereof is inward with respect to the goal line, whereby the puck registers the highest signal strength from the wire after passing over the goal line. Furthermore, the wire 110 is either flush against the ground surface or buried within the surface, whereby a slot can be created through the ice across the mouth of the goal and the wire can be burred therein and covered with ice or snow thereafter. This ensures the physical presence of the wire will not interfere with the puck if it is traveling over the goal line and along the ice surface.

(13) The present invention describes an illuminating hockey puck. The device comprises a standard sized hockey puck without any structural changes. Internally, the puck of the present invention includes a light and a receiver. The receiver is synced with a transmitter along the goal post. The receiver activates the illumination source in the puck when the puck crosses the goal line, causing the light inside the puck to illuminate. The present invention ensures the accuracy of scored goals and eliminates the need for instant replay, and also increases overall enjoyment for hockey fans watching at the rink and at home.

(14) In one further embodiment of the hockey puck, the puck itself is a bright neon color that is more readily visible without illuminating the light source. The flat sides of the puck may be a bright neon color, while the rounded sides are black to counterbalance the neon color for the players. Alternatively the neon color may be disposed along the rounded sides while the flat surfaces are a black rubber color.

(15) It is submitted that the instant invention has been shown and described in what is considered to be the most practical and preferred embodiments. It is recognized, however, that departures may be made within the scope of the invention and that obvious modifications will occur to a person skilled in the art. With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of the invention, to include variations in size, materials, shape, form, function and manner of operation, assembly and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by the present invention.

(16) Therefore, the foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the invention.
