T-tube 136 includes opposed openings 136 b and 136 c, and an intermediate opening 136 a which faces perpendicular to the opposed openings 136 b and 136 c. It should be noted that tube 130 is coupled to T-tube 136 so that upper tube opening 132 faces intermediate opening 136 a of T-tube 136.
In this embodiment, hockey practice machine 100 includes a tray tube 137 which is coupled between opening 136 b of T-tube 136, and a tray 107. Tray 107 is positioned proximate to top wall 105, and is used to carry one or more objects, such as hockey balls 160.
In this embodiment, hockey practice machine 100 includes a motor 141 which is positioned proximate to opening 136 c of T-tube 136 so motor 141 is opposed to opening 136 b and tray tube 137. In this embodiment, hockey practice machine 100 includes a dispensing arm 150 operatively coupled to motor 141. Dispensing arm 150 extends between motor 141 and tray tube 135. Dispensing arm 150 is operatively coupled to motor 141 so that it rotates in response to the operation of motor 141. Dispensing arm 150 can be of many different types, one of which will be discussed in more detail presently.
FIGS. 5 a and 5 b are side and perspective view, respectively, of dispensing arm 150. In this embodiment, dispensing arm 150 includes a shaft 151, which is cylindrical in shape. In this embodiment, dispensing arm 150 includes a plurality of arms coupled proximate to one arm of shaft 151. In this embodiment, dispensing arm 150 includes three arms, which are denotes as arms 152, 153 and 154, for illustrative purposes. Arms 152, 153 and 154 extend outwardly from shaft 151 and are equidistantly spaced apart from each other. It should be noted that the end of shaft 151 opposed to arms 152, 153 and 154 is received by motor 141. In this way shaft 151 rotates in response to the operation of motor 141. Further, arms 152, 153 and 154 rotate in response to the rotation of shaft 151. The operation motor 141, and the rotation of dispensing arm 150, will be discussed in more detail below.
Referring to FIGS. 4 a, 4 b and 4 c, hockey practice machine 100 includes a speed controller 142 operatively coupled to motor 141. Speed controller 142 can be operatively coupled to motor 141 in many different ways. In this embodiment, speed controller 142 is operatively coupled to motor 141 through a control switch 143, wherein control switch 143 is shown in FIG. 1 d. As will be discussed in more detail below, speed controller 142 controls the speed with which dispensing arm 150 rotates.
In this embodiment, power is provided to motor 141 through a plug 144, which is connected to speed controller 142. Control switch 143 is repeatably moveable between activated and deactivated conditions, wherein power is provided to motor 141 in response to control switch being in the active condition and power is not provided to motor 141 in response to control switch being in the deactivated condition.
In operation, hockey balls 160 are positioned on tray 107, wherein one hockey ball is denoted as hockey ball 161 in FIG. 4 c. Tray 107 is sloped so that the hockey balls positioned on it are biased to move to the opening of tray tube 137 that is positioned towards tray 107. In this way, the hockey balls move to T-tube 136 through tray tube 137. In particular, the hockey balls move through the opening of T-tube 136 opposed to motor 141.
During the operation of motor 141, dispensing arm 150 rotates. In particular, during the operation of motor 141, shaft 151 rotates, and arms 152, 153 and 154 rotate in response. Arms 152, 153 and 154 are positioned proximate to the intermediate opening of T-tube 136 so that the hockey ball moving through the opening of T-tube proximate to tray tube 137 is moved through the intermediate opening of T-tube 136. In this way, dispensing arm 150 moves an object through the intermediate opening of T-tube 136 in response to the object moving through one of the opposed openings, and in response to rotation of dispensing arm 150.
As mentioned above, T-tube 136 is coupled to drop tube 130 so that upper drop tube opening 132 faces the intermediate opening of T-tube 136. Hence, the hockey ball that is moved through the intermediate opening of T-tube 136 in response to the rotation of dispensing arm 150 moves through upper drop tube opening 132. In this way, dispensing arm 150 moves an object through drop tube 130 in response to the object moving through one of the opposed openings of T-tube 136, and in response to rotation of dispensing arm 150.
The hockey ball drops through drop tube body 131 and upper and lower drop tube elbows 134 and 135, as well as through lower drop tube opening 133. As mentioned above, lower drop tube opening 133 is positioned proximate to front sidewall opening 110. Hence, the hockey ball flows through front sidewall opening 110 and away from front wall 101.
It should be noted that the number of hockey balls which flow through front sidewall opening is adjustable in response to adjusting speed controller 142. As the rotation speed of dispensing arm 150 increases and decreases in response to adjusting speed controller 142, the number of hockey balls flowing through front sidewall increases and decreases, respectively. Further, as the rotation speed of dispensing arm 150 increases and decreases in response to adjusting speed controller 142, the number of hockey balls flowing through drop tube 130 increases and decreases, respectively.
It should be noted that the speed of the object through lower tube opening 133 corresponds to a drop distance D_Dropof tube 130, which is shown in FIGS. 3 a, 3 b 4 b and 4 c. In this embodiment, drop distance D_Dropof tube 130 corresponds to a distance between upper tube elbow 134 and lower tube elbow 135. As the distance between upper tube elbow 134 and lower tube elbow 135 increases and decreases, the speed of the object through lower tube opening 133 increases and decreases, respectively. In one embodiment, drop distance D_Dropcorresponds to a distance between the lower portion of upper tube elbow 134 and the upper portion of lower tube elbow 135. In one embodiment, drop distance D_Dropcorresponds to a distance between the lower portion of upper tube elbow 134 and the lower portion of lower tube elbow 135.
It should also be noted that the speed of the object through lower tube opening 133 corresponds to a distance D_Shelfbetween shelf 120 and bottom wall 106, which is shown in FIGS. 2 a, 2 b, 4 b and 4 c. As distance D_Shelfincreases and decreases, the speed of the object through lower tube opening 133 increases and decreases, respectively. Drop distance D_Dropcorresponds to distance D_Shelf. As drop distance D_Dropincreases and decreases, distance D_Shelfincreases and decreases, respectively.
The embodiments of the invention described herein are exemplary and numerous modifications, variations and rearrangements can be readily envisioned to achieve substantially equivalent results, all of which are intended to be embraced within the spirit and scope of the invention as defined in the appended claims.
