Definitions

  • This invention relates to an improved self-loading, remotely operable and variable, portable ball throwing device.
  • Rowe U.S. patent 4,271,813 Another manually operated pitching machine is dis ⁇ closed in Rowe U.S. patent 4,271,813.
  • the Rowe machine is a tripod designed to generally resemble a human being with a spring torsioned arm that is drawn back by the batter to pick up a large Softball. The batter then slips the pull string off of the bat as he stands at the plate, the arm is released and the softball is "thrown.”
  • a ball throwing device which is remotely adjustable and operable; self-loading; capable of alternating pitches, one after the other, up and down, within the batting box; capable of producing high and low velocity pitches; capable of throwing fly and ground balls; and which is simple in design, collapsible and portable.
  • the ball throwing device of the present invention includes a frame having an arm rotatably mounted thereon.
  • a "hand" means for holding a ball is mounted to the free end of the arm.
  • One or more elastic biasing means such as surgical tubing, are connected to the arm and to the frame and draw the arm towards the front of the frame.
  • an arm positioning means such as a nylon cord.
  • the nylon cord is passed over a pulley at the rear of the frame and passes forward and concludes in a hook, or anchoring means, attached to the opposite end of the cord.
  • a rectangularly shaped peg board is designed to receive and retain the anchor attached to the cord in one free end of the board.
  • the peg board With the anchor attached, the peg board is drawn back until the arm is drawn back until the arm is drawn to the vertical position. At that point, the peg board is secured to the ground by means of a stake driven through a hole in the rear end of the peg board. Attached between the ends of the positioning cord is a cocking handle.
  • the cocking handle has a peg which conforms to holes drilled into the peg board numbered consecutively from "1" upward starting at the free end of the peg board where the anchor is located.
  • a removably attachable self-loading trough is attached to the frame and designed so as to admit a ball into the hand when the cocking handle draws the arm past horizontal to its full rearward position.
  • the cocking handle is grasped, the handle is pulled away from the frame which draws the arm backwards and a ball is loaded into the hand.
  • the operator then places the cocking handle peg into a preselected hole in the peg board.
  • the batter then assumes a natural batting stance and, with his foot, simply lifts the cocking handle slightly causing the peg to be withdrawn from the peg board and the surgical tubing to draw the arm forward in ever increasing speed until the ball is launched towards the batter.
  • the batter desire to lower the pitch he simply places the cocking handle in a number lower than the one first selected. If the batter desires to raise the pitch, he places the cocking handle in the number higher than the one first selected. The same pitch may be thrown again and again and again by simply replacing the cocking handle in the originally selected hole.

  • the hole 52 through which the user may place his fingers to grasp-handle 22 is also shown.
  • Handle connecting cord 54 is shown connected by handle connection 56, of any conventional design known in the art, in this case a metal ring.
  • Cord 54 is also connected by position ⁇ ing cord connection 58 to arm positioning cord 20.
  • FIGURE 3 also illustrates removably attachable anchor 60 which has a peg 62, shown in dotted lines, designed to conform to a large number of adjustment holes 64 as does peg 48.
  • Peg board 24 has stake hole 66 through which any convenient stake (not shown) may be driven in order to secure peg board 24 to the ground.
  • FIGURE 4 ball thrower 10 is shown in the uncocked position. Also illustrated in FIGURE 4 is supplemental power section 68 with additional power length 18'. Further, power section connections 70 and 70' are shown, in this instance consisting of hooks and rings of conventional design known in the art and not described further herein. Arm connections 72 and 72' are similarly disclosed, yet arm connections 72 and 72' have unclosed loops so that power lengths 18 and 18' may be easily removed and attached thereto.
  • power length 18 is designated as a length of 3/4 inches O.D. surgical tubing, "A”, in the low position and power length 18* is designated as a length of 5/8 inches O.D. surgical tubing, "B", in the high position, the following eight positions 1 to 8, slowest to fastest, are possible:
  • This speed range requires two of each type power length. Six speeds are available if only one type of each power length is used thereby excluding speeds 5 and 8 as set forth above.
  • FIGURES 4 and 5 illustrate another important feature of invention 10 wherein power length(s) 18 (and 18*) have one end secured at 70 (70') in an elevated position that "points" the power lengths directly at the target area somewhat above the batter's box. As a result, arm 14 is pulled forcefully directly towards the target.
  • arm positioning cord attachment 74 attached to the back of arm 14; dead man stake 76; and rear end stake 78.
  • FIGURE 5 shows ball thrower 10 in the cocked position with ball 28 in cup 16 ready to be thrown.
  • FIGURE 5 does not show supplemental power section 68 attached, although it is obvious that it may be used in addition to the primary power section 40.
  • Both FIGURE 4 and FIGURE 5 show that arm positioning cord 20 passes over the top of the foot of dead man section 42 on its way to the rear of frame 12 where it passes around pulley 32 and is connected to arm 14 at arm positioning cord attachment 74.
  • FIGURES 6, 7, and 8 are close ups of some particulars of the ball thrower 10.
  • FIGURE 6 illustrates hand 16.
  • top section 80 of hand 16 is flat and is bent in an approximately 90 degree angle from the rear section 82.
  • Top section 80 has central groove 84 into which some portion of ball 28 will rest. Ball 28 should rest and be supported partially by rear section 82 and top section 80 as shown in FIGURE 6-A.
  • Hand 16 may also be rotatably connected to arm 14 by means readily known in the art, but not shown. To function properly, hand 16 should sit at an angle of approximately 135° from arm 14. With a rotatable hand 16, the hand can be rotated forwards a few degrees for faster speeds and backwards a few degrees for slower speeds. This ensures delivery of ball 28 exactly on target.
  • FIGURE 7 illustrates power length 18 and tapered connector 86.
  • Tapered connector 86 has an integral flattened section 88 through which connection hole 90 is drilled.
  • Restraining groove 92 is formed in the body of tapered connector 86 so that when tapered connector 86 is inserted into power length 18, restraining pincher 94, of ordinary design known in the art, can be located over restraining groove 92 and drawn tight so that power length 18 is firmly held within restraining groove 92 and tapered connector 86 is securely attached to power length 18 thereby.
  • the tapered shape of connector 86 reduces wear and tear on surgical tubing 18 as it stretches over the connector.
  • FIGURE 8 illustrates the lower rear section of self- loading trough 30 with ball 28 in place.
  • trough 30 is removably attachable to frame 12 in the area of rotatable attachment 34 so that the front end of trough 30 is elevated above the ground and that balls 28 roll, by force of gravity, to the rear section illustrated in FIGURE 8.
  • the rear section of trough 30 extends beyond the rear end of frame 12 as illustrated, once again, in FIGURES 4 and 5 for example, and has a loading lever 96 constantly biased by spring 98 in the upward position so that loading lever 96 prevents balls 28 from exiting trough 30 at the rear.
  • Trough 30 and arm 14 and handle 16 are designed so that when arm 14 is drawn backwards, hand 16 pushes lever 96 down and all ⁇ ws ball 28 to roll into hand 16.
  • FIGURE 8 shows lever 96 in the down position thereby allowing ball 28 to roll free of trough 30.
  • loading lever 96 will be raised by spring 98 so that additional balls 28 are retained within trough 30.
  • peg board 24 is located in the preferred area, batter's box, selected by batter 26 by means of driving a stake through stake hole 66.
  • Removably attachable anchor 60 is then attached to peg board 64 at the free end of peg board 24.
  • the batter 26 then walks to ball thrower 10, grabs frame 12 and walks backwards from the batter's box with frame 12 until arm 14 has been pulled to an upright position approximately perpendicular to the ground.
  • Ball thrower 10 is designed so that power length 18, when' arm 14 is in the perpendicular position, will be stretched to approximately 100% of its original length. As a result, when in this "uncocked" position as shown in FIGURE 9 for example, power length 18 will be stretched and pulling on arm 14.
  • batter 26 then grasps cocking handle 22, and by means of handle connect ⁇ ing cord 54, pulls arm positioning cord 20 towards the batter's box. Because arm positioning cord 20 is attached to arm 14 at attachment 74, arm 14 is drawn backwards and power length 18, and 18' if attached, is stretched fur- ther. Batter 26 continues to pull cocking handle 22 until hand 16 depresses loading lever 96 and ball 28 is released into hand 15. The batter then eases arm 14 forward and places peg 48 in any one of the numbered adjustment holes 64 in peg board 24. the ball thrower 10 is now in the "cocked" position as illustrated in FIGURE 10. At this point, batter 26 assumes a normal batting stance.
  • cocking handle 22 has upwardly sloping handle 50, as shown in FIGURES 10 and 11 for instance, batter 26 then can use his foot to gently lift cocking handle 22 just enough to release peg 48 from adjustment hole 64.
  • power length 18 begins to draw, with ever increasing power, arm 14 rapidly forward towards the batter.
  • arm positioning cord 20 steps the forward motion of arm 14 and the ball 28 is thrown forward towards the batter.
  • arm 14 is constructed of any light weight resilient and strong material preferably with some small degree o flexibility so that there is not the abrupt impact stop of previous devices but so that it duplicates the natural fluid throwing motion, as close as possible, of the human arm.
  • the batter has control over the area where the ball is to be pitched to a degree heretofore unknown. That is, by the simple means of placing cocking handle 22 in a higher numbered adjustment hole 64, the ball will be raised in the strike zone. By placing cocking handle 22 in a lower numbered adjustment hole 64, than the previous pitch, the ball will be lowered in the strike zone.
  • the benefits of this are obvious in that not only can a single batter practice pitches in a. wide variety of locations, but batters of different heights may be easily accommodated one after another without complicated removal and reassembly of the device as required by prior art machines.
  • FIGURE 2 An added and extremely important advantage of this device is the fact, as shown in FIGURE 2, that it may be disassembled, partially or totally, into a small number of pieces for transportation.
  • the device is not bulky, it is lightweight and easy to transport, assemble, set up, and utilize.
  • a single operator may utilize the invention or, a coach may control the delivery of the pitch to the batter by simply holding onto cocking handle 22, not placing it in an adjustment hole 64, and releasing cocking handle 22 when the coach and the batter are ready.
  • the ball thrower of the present invention has been disclosed in connection with manual operation, it should be appreciated that the device is capable of attachment to a small electrically driven winch (not shown) that would operate arm 14 upon demand of batter 26 in much the same way as the manual cocking handle 22 operates.
  • the present invention provides an improved ball thrower which can be easily manipulated in order, for example, to vary the location of pitches to an individual batter; to accommodate for different height batters; to vary the velocity of thrown pitches; as well as enabling the batter to throw fly balls, strikes or grounders.
  • the ball thrower is simple and reliable, easy to assemble and may be remotely operated by a single individual, the batter.
  • the ball thrower of the present invention has a variety of important advantages over the prior art.

Abstract

Lance-balle (10) portatif, à fonctionnement variable, actionnable à distance, et à auto-chargement. Un bras (14) ayant une main (16) fixée au bras est tendu, dans la position non-armée, par des moyens élastiques de sollicitation (18), tels qu'un tubage chirurgical, vers l'avant. Un batteur (26), jouant également le rôle d'opérateur, peut, au moyen d'une poignée d'armement (22), actionner le bras (14) vers l'arrière, ramasser une balle (28) d'une auge d'auto-chargement (30), et remettre le bras (14) dans la position armée. Prenant ensuite la posture naturelle du batteur, le batteur (26) peut alors, avec son pied, libérer la poignée d'armement (22) permettant ainsi au moyen de solicitation élastique (18) de tirer avec une vitesse toujours croissante le bras (14) vers la position non armée. En atteignant la position non-armée, la balle (28) est lancée d'une manière fluide suivant un angle consistant vers le batteur (26). L'invention permet au batteur (26) d'augmenter ou de diminuer la hauteur de la trajectoire dans la zone de frappe du batteur en plaçant la poignée d'armement (22) dans l'un des nombreux trous de réglage de sorte que le batteur peut s'entraîner avec des trajectoires basses ou hautes, ou bien différents batteurs ayant des hauteurs différentes peuvent régler rapidement le degré d'inclinaison des trajectoires en fonction de leurs besoins. De plus, le dispositif permet au batteur de lancer des balles aériennes, des ''strikes'' (coups du batteur) ou des coups roulés. Le dispositif est facile à monter et à démonter, est léger et portatif.
