Hockey training apparatus
BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     The present invention relates generally to sports training aids and game apparatuses and more particularly, to a hockey training aid and game apparatus. 
     2. Description of the Prior Art 
     Hockey training aids and/or game apparatuses are well known in the art as exemplified by the following U.S. Pat. Nos. 3,709,489 of Holleran et al; 3,912,269 of Barlow; 3,970,306 of Smith; 4,105,210 of Jones et al; and 4,560,163 of Erickson. 
     The device in the Holleran et al patent is very large and not easily transported. The device in the Barlow patent is small and easily transported, but it does not include a life-size hockey stick. Similarly, the device in the Smith patent does not include a hockey stick. The device in the Jones et al patent does not have means for measuring accuracy in puck shooting. The device in the Erickson patent is very large and not easily transported and does not have means for measuring accuracy in puck shooting. 
     Moreover, the prior art hockey training aids and/or game apparatuses do not provide means for measuring both inaccurate shots and accurate shots. In addition, the prior art devices generally require the presence of two or more competitors. It would be desirable, however, if a device were provided which enabled a person working alone to improve the person&#39;s puck shooting skills. 
     Thus, while the foregoing body of prior art indicates it to be well known to use hockey training and/or game devices, the provision of a simple, portable, and cost effective device is not contemplated. The prior art does not provide does not hockey training devices that include means for measuring accuracy in puck shooting. In addition, the prior art does not provide hockey training devices with means for measuring both inaccurate shots and accurate shots. The prior art does not provide a device which enables a person working alone to improve the person&#39;s puck shooting skills. The foregoing disadvantages are overcome by the unique hockey training aid and game apparatus of the present invention as will be made apparent from the following description thereof. Other advantages of the present invention over the prior art also will be rendered evident.

     DESCRIPTION OF THE PREFERRED EMBODIMENT 
     With reference to the drawings, a new and improved hockey training aid and game apparatus embodying the principles and concepts of the present invention will be described. 
     Turning initially to FIGS. 1-7, there is shown a first exemplary embodiment of the hockey training aid and game apparatus of the invention generally designated by reference numeral 10. In its preferred form, hockey training aid and game apparatus 10 includes a portable housing 12 which includes a base unit 14 and a cover 16 connected to the base unit 14. In FIG. 1, the hockey training aid and game apparatus 10 of the invention is shown in a closed arrangement with the cover 16 fastened to the base unit 14 by locking clasps 9. A handle 7 is provided for ease of carrying the portable apparatus 10. 
     As shown in FIG. 2, the base unit 14 includes a floor 18 and four side walls 20 connected to the floor 18. FIG. 2 shows the apparatus of the invention in an open arrangement in preparation for using. The floor 18 contains indicia 24 representing a hockey rink. For example, the indicia 24 can include a center red line, blue lines, etc.. The cover 16 includes first brackets 30 for retaining a collapsible stick 28 in a collapsed condition when the hockey training aid and game apparatus 10 is transported. A puck 22 is shown resting on the floor 18. 
     As shown in FIG. 4, the stick 28 is capable of being assembled into a functional hockey stick when the hockey training aid and game apparatus 10 of the invention is used. More specifically, handle element 17 is connected to puck-hitting element 19 using a male element 21 which fits into a complementary female recess 23. To lock the handle element 17 and the puck-hitting element 19 together once the male element 21 is inserted into the female recess 23, a pin 25, located at one end of flexible strip 27 retained on handle element 17, is inserted into hole 29 on puck-hitting element 19. 
     A first sensor assembly 34, for monitoring accurate puck handling, is shown in FIG. 5 and is located under the center 11 of the floor 18. A scoring and control assembly 32, for scoring puck handling, is placed onto wall 20 when the hockey training aid and game apparatus 10 is used. More specifically, as shown in FIG. 3, nipples 13 project from the bottom of the scoring and control assembly 32, and the nipples 13 fit into rubber grommets 15 located in the wall 20, whereby the scoring and control assembly 32 is secured onto the wall 20. 
     As shown in FIG. 6, the side walls 20 include resilient bumpers 26 which may be made from an inexpensive, resilient foam rubber. In addition, the floor 18 can include a slippery surface layer 31, such as one made from a polytetrafluoroethylene polymer such as Teflon (™). 
     As shown in FIG. 2, the cover 16 includes second brackets 50 for retaining the scoring and control assembly 32, using complementary connectors thereon (not shown) when the hockey training aid and game apparatus 10 is transported. The cover 16 is connected to the wall 20 by means of hinges 39. 
     Turning to the schematic block diagram in FIG. 7, the first counter assembly 38 is connected to the first sensor assembly 34, for counting monitored instances of accurate puck handling sensed by the first sensor assembly 34. Timer 47 permits the first counter assembly 38 to run and shuts it off after a predetermined time expires. The first counter assembly 38 is also connected to a first count display unit 33 which the count of accurate puck handling. The scoring and control assembly 32, shown as the components contained within the dashed box, further includes the second sensor assembly 36 which monitors inaccurate puck handling. A second counter assembly 44 is connected to the second sensor assembly 36 and counts monitored instances of inaccurate puck handling sensed by the second sensor assembly 36. Moreover, the second counter assembly 44 is also shut off by the timer 47 after the predetermined time expires. 
     The scoring and control assembly 32 also includes a sounding device 48, such as a simple buzzer, controlled by the second sensor assembly 36, for sounding when inaccurate puck handling is sensed by the second sensor assembly 36. 
     As shown in FIG. 5, the first sensor assembly 34 includes a first puck sensor 40 located in a center of the floor 18. As shown in FIG. 6, the second sensor assembly 36 includes a second puck sensor 46 located near a side wall 20 in the floor 18. Either a plurality of second puck sensors 46 or a ribbon of sensors can be arrayed along lines 45 (see FIG. 2) near side walls 20 in the floor 18. 
     Preferably, the first puck sensor 40 and the second puck sensors 46 are responsive to magnetic flux. In this respect, they can be conventional sensors that depend upon the Hall effect. The puck 22 includes a permanent magnet 35 (see FIG. 10). 
     All of the electronic components shown in block form in FIG. 7 can be implemented by conventional electronic components, especially using integrated circuits for counter, displays, and timers. The first and second sensors can be implemented by Hall effect sensors which respond to a change in magnetic flux that occurs when a magnet-containing puck moves past a Hall effect sensor. 
     Turning to FIGS. 8-10, a second embodiment of a puck 22 used in the hockey training aid and game apparatus 10 of the invention is shown. Reference numerals are shown that correspond to like reference numerals that designate like elements shown in the other figures. In addition, the puck 22 includes a hollow puck housing 52 having an interior chamber 54 defined by the puck housing 52. A filler hole 56 is located in a wall 58 of the puck housing 52 and is used for admitting a quantity of lubricant powder 60, such as talcum powder, into the interior chamber 54. A filler hole cover 62 is used for covering the filler hole 56. A plurality of weep holes 64 are located in a bottom wall 66 of the puck housing 52 for permitting lubricant powder 60 to pass from the interior chamber 54 to a bottom outer surface 68 of the puck housing 52. A quantity of permanent magnetic material 35 is retained in a bottom wall 72 of the puck housing 52. 
     The structural components of the invention can be made from inexpensive materials such as plastics. The collapsible hockey stick can be made from wood, if desired. 
     In using the hockey training aid and game apparatus 10 of the invention, every time a player moves the puck 22 across the first sensor assembly 34, the first counter 38 will add an additional increment to its cumulative total. The first counter 38 will continue to add increments until the time runs out; that is the timer 47 turns off. The cumulative total can be the player&#39;s score. 
     To beat one player&#39;s score, another player would be forced to handle the stick 28 faster. In this respect, a player can also try to beat his previous score. 
     However, if a player loses control of the puck 22, it would slide either to the left or right. If the puck 22 then crosses the blue line, the second sensor assembly 36 would sense this, and two results will take place: a sounding device (such as a buzzer or a bell) will sound; and the second counter 44 will be incremented by one unit. After the timer 47 runs out of its predetermined time, a final score can be determined by subtracting the total from the second counter 44 from the first counter 38. 
     A novice player, the player can look down on the puck when playing, and as his score would improve, the player&#39;s puck handling skills would also improve. To further improve stick handling skills, a player can stike the puck without looking at the puck. This would be an increased challenge. 
     To further improve on stick handling skills, a left handed player can stand with the left side of his body facing the apparatus and handle the stick in that fashion. Conversely, a right handed player can stand with the right side of his body facing the apparatus and handle the stick in that fashion. 
     The score board can be from 0-100 points, and the player who reaches 100 points first would be the winner of the game one. There can be a three game format. To register the score, a sliding register device can be employed. 
     The hockey training aid and game apparatus of the invention provides excellent off ice training for all players. Using the apparatus can improve hand and eye coordination and increase a player&#39;s skill either to pass a puck to team mates with ease and accuracy or to receive a pass with greater ease. 
     With the invention, a player can get stick handling practice and improve puck shooting accuracy without undergoing collisions with opponents and without risking serious injury. 
     The invention is portable and can be used virtually anywhere. For example, the apparatus can be used in a dressing room prior to a game or practice as a warm up. The apparatus can be used by amateurs, by professionals, by men, by women, and by children. The apparatus can be used in the off season in homes or at playgrounds. 
     By a person keeping his stick handling and puck shooting skills at a high level of performance, the player can impress oneself, team mates, coaches, managers, parents, friends, fans, other teams, and scouts. 
     It is apparent from the above that the present invention accomplishes all of the objects set forth by providing a new and improved hockey training aid and game apparatus that is low in cost, relatively simple in design and operation, and which may advantageously be used as an easily transported hockey training aid and game apparatus that includes a life-size hockey stick, that provides means for measuring both inaccurate shots and accurate shots, and that enables a person working alone to improve the person&#39;s puck shooting skills. 
     With respect to the above description, it should be realized that the optimum dimensional relationships for the parts of the invention, to include variations in size, form function and manner of operation, assembly and use, are deemed readily apparent and obvious to those skilled in the art, and therefore, all relationships equivalent to those illustrated in the drawings and described in the specification are intended to be encompassed only by the scope of appended claims. 
     While the present invention has been shown in the drawings and fully described above with particularity and detail in connection with what is presently deemed to be the most practical and preferred embodiments of the invention, it will be apparent to those of ordinary skill in the art that many modifications thereof may be made without departing from the principles and concepts set forth herein. Hence, the proper scope of the present invention should be determined only by the broadest interpretation of the appended claims so as to encompass all such modifications and equivalents.
