Description

BACKGROUND OF THE INVENTION

The present invention relates to automatic ball dispensers and more particularly to golf ball dispensers that automatically position dispensed golf balls on a tee.

The use of automatic golf ball dispensers is well known, however, conventional dispensers have a number of disadvantages. Among these disadvantages is the tendency of feed paths to clog as stored balls press against each other, especially when the dispenser is fully loaded. Conventional dispensers are also subject to major damage when a user accidentally hits a ball positioning arm with a golf club before it is moved away from the tee. Another disadvantage of a conventional dispenser is that it cannot dispense golf balls to a mat for practice with an iron, but can only position golf balls on a tee.

OBJECTS AND SUMMARY OF THE INVENTION

Accordingly, it is an object of the invention to provide an automatic golf ball dispenser that overcomes the drawbacks of the prior art.

It is a further object of the invention to provide a golf ball dispenser that is not subject to clogging, regardless of the number of golf balls loaded into it.

It is a still further object of the invention to provide a golf ball dispenser that compensates for wear and provides extended operation with minimal operating failures.

It is a still further object of the invention to provide a golf ball dispenser that is not seriously damaged when a ball positioning arm of the dispenser is hit with a club during a practice swing.

It is a still further object of the invention to provide a dispenser that can, in addition to setting up golf balls on a tee, dispense a plurality of golf balls to a mat for practice with golf irons.

Briefly stated, the present invention provides an automatic golf ball dispenser that dispenses golf balls to a tee for driving or directly to a mat for iron shots. The dispenser includes a breakaway captive setting arm that sustains minimal damage when hit by a club. The dispenser also includes a series of baffles and means for rotating stored golf balls to prevent clogging. A stopper retards balls in a supply chute while one ball is being teed, and while a setting arm is being returned to a ball-receiving position.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

Referring to FIG. 1 there is shown an automatic golf ball dispenser 100 that includes five major units. A stacking unit A stores and supplies golf balls G to a chute unit B. Chute unit B is housed in a narrow rectangular enclosure 25 whose upper left corner terminates obliquely. Chute unit B transports golf balls G from stacking unit A to a setting arm unit C in enclosure 25.

A swingable set arm 41 of setting arm unit C accepts golf balls G from chute unit B and positions them on a tee 63. A chute 20 located at a rear side portion of setting arm unit C can be used to dispense golf balls G to a shot mat 62 for hitting iron shots directly from a surface of shot mat 62. A box shaped control unit E contains the controls used to operate dispenser 100.

Control unit E, located on top of stacking unit A, contains a card reader 71 on an upper right hand corner and a condition indicator 74 on a forward upper surface, as shown on the figure. Condition indicator 74 lights green to indicate that dispenser 100 is on and operating, and lights red to indicate a trouble or malfunction. Card reader 71 reads a card to set in a quantity of prepaid golf balls G for dispenser 100 to dispense to a user.

Along the side of chute unit B facing a mat unit D, a plurality of viewing ports 25a allow a user to determine that a supply of golf balls G are loaded in dispenser 100. The side of chute unit B also contains a stop button 73 to stop dispenser 100 and an iron button 72, which causes dispenser 100 to dispense a plurality of golf balls G through a chute 20a directly to shot mat 62 of a base mat 61 on mat unit D. Golf balls G, on shot mat 62, permit practice with an iron.

Referring to FIGS. 2A and 2B, a base 20 supports stacking unit A, chute unit B and setting arm unit C in line. Mounted on a left hand portion of base 20, stacking unit A generally comprises a rectangular box 10 having a maintenance door 10c (shown in FIG. 1) on its side. A chute 22, which has a roughly "U"-shaped cross section, extends at one end from chute unit B into box 10 at a point approximately one half the distance closer to a side wall 12a than a side wall 11a. A second end of chute 22 terminates at a point adjacent to setting arm unit C with a gate 22b. A visor 22c, disposed across a top member of gate 22b facing away from setting arm unit C, serves to guide golf balls G through gate 22b.

Within box 10, a plate 11, that extends from a rear wall 10a to a front wall 10b, slants downward from a sidewall 11a to a position adjacent to a first side of chute 22, while a plate 12 that extends from rear wall 10a to front wall 10b slants downward from side wall 12a to a position adjacent to a second side of chute 22. Plate 11 and a plate 12 form a trap that guides golf balls G to chute 22 and prevents them from falling to the area below chute 22.

Referring to FIGS. 2C and 2D, an upper baffle plate 14 that extends from rear wall 10a to front wall 10b is disposed above plate 12 and slopes downward from side wall 12a approximately halfway across box 10. A free edge of upper baffle plate 14 extends over chute 22. A lower baffle plate 13, that extends from rear wall 10a approximately three fourths of the distance to front wall 10b, slopes slightly downward from side wall 11a to a position above the first side of chute 22 and just under the free edge of upper baffle plate 14.

Referring again to FIGS. 2a and 2b chute 22 is pivotally connected to a stand 21 on base 20 by a pivot 21a. This allows chute 22 to be held parallel to base 20 or slanted downward from box 10. A groove 22a runs the length of the bottom of chute 22 to guide golf balls G along chute 22. A sliding rail 23 is slidably disposed along the length and within groove 22a. A pin 23a, attached to a bottom surface of sliding rail 23, projects downwardly through a slot (not shown) in the bottom of groove 22a. A return spring 24 is connected between pin 23a and stand 21 to bias sliding rail 23 to its forward-most position (left in the figures). A motor 32 is secured to base 20 by a bracket 31, both disposed under a horizontal plate 30.

Referring to FIGS. 3A, 3b, and 3c, a rotary crank 33 is drivably connected by a shaft 32a of motor 32. The rotational position of crank 33 is monitored by a photo sensor 39. A crank arm 34, which extends through horizontal plate 30, is pivotally connected at one end to crank 33. A second end of crank arm 34 is pivotally connected to a bottom end of a frame 35 of chute 22 and a rear end of a bar 37. A pin bracket 36, mounted on horizontal plate 30, pivotally supports bar 37 by a pin 36a. A forward portion of bar 37 extends along a first side of chute 22. A cam 38 is mounted on a rear central upper surface of horizontal plate 30 so as to extend upward at a slight rearward angle through a slot 22d in chute 22 and a slot 23b in sliding rail 23.

Referring now to FIGS. 4A and 4B, setting arm unit C comprises an arm assembly 4 and an arm drive assembly 5. A set arm 41 of arm assembly 4 is rotatably supported at a ball receiver 41a end on a vertical shaft 42 by a support structure 41f so that the set arm 41 can be rotated outward from dispenser 100. An upward projection of support structure 41f, together with a stopper plate 41e form a golf ball guide assuring that golf balls G from chute 22 are properly positioned on ball receiver 41a, which is bent upwards to receive them.

A guide rail 41b portion of set arm 41 is separably joined to ball receiver 41a. Guide rail 41b is separably attached to minimize the possibility of severe damage to dispenser 100 should set arm 41 be struck accidentally by a golf club swing. If struck, guide rail 41b readily separates from ball receiver 41a, thus avoiding damage to ball receiver 41a and its supporting mechanism. A spring 41d, connected between ball receiver 41a and guide rail 41b, prevents guide rail 41b from being driven far from dispenser 100. Guide rail 41b can easily be rejoined to ball receiver 41a when separated.

A "U"-shaped ball supplier 41c is disposed at an end of guide rail 41b away from ball receiver 41a. An open side of ball supplier 41c faces away from dispenser 100 in the direction of its travel. A magnet holder 47a is mounted on base 20 between set arm 41 and a wall of setting arm unit C away from the direction of travel of set arm 41. A magnet 47, attached to magnet holder 47a, holds set arm 41 in place while it is in a golf ball G receiving position.

Components of arm drive assembly 5 are generally located at an end of base 20 opposite box 10. A bracket 51, mounted on an end of base 20, supports a motor 52. A shaft 52a of motor 52 drives a crank 53, which is coupled to a bottom of support structure 41f by a crank arm 54. Rotation of crank 53 causes crank arm 54 to pull against support structure 41f, causing set arm 41 to swing between the golf ball receiving position and a golf ball tee up position shown in FIGS. 5 and 8. A photo sensor 55, mounted on base 20 adjacent to a perimeter of crank 53, senses a detector plate 53a to determine the instantaneous position of set arm 41. A magnet 48 is mounted on base 20 in the rotational path of a stopper plate 44 on set arm 41. When set arm 41 is being swung to the tee up position, its motion is blocked at the correct position as stopper plate 44 contacts magnet 48. Magnet 48 then magnetically holds set arm 41 in position until it is returned to its receiving position by the action of motor 52. An infra-red sensor 46 is mounted on a wall 43 of setting arm unit C with line of sight contact with tee 63 to sense the presence of a golf ball G.

Referring again to FIG. 1, mat unit D includes a base mat 61 that is positioned against, and centered with, setting arm unit C. Shot mat 62 is centered on base mat 61 to provide a realistic surface for practicing with irons. Tee 63 is mounted on shot mat 62 in a precise position to receive golf balls G from setting arm unit C.

Referring to FIG. 10, there is shown a block diagram of control unit E. Control unit E determines a required operating sequence depending on input signals from a variety of sources. These sources include card reader 71, iron button 72, stop button 73, a microswitch 45, infra-red sensor 46, and photo sensor 55. Using these input signals, control unit E generates control signals to operate motors 32 and 52 to carry out all required sequences of operation. The controller also uses these inputs to monitor the condition of dispenser 100 and light indicator 74 green or red as required.

Referring to FIG. 11, dispenser 100 operates in the following sequence. Initially, chute 22 is loaded with a plurality of golf balls G with the foremost golf ball G in position on ball receiver 41a of set arm 41. With the insertion of a card in 71, operation is initiated. Control unit E determines whether or not iron button 72 has been pressed (101) and if microswitch 45 has been closed by a golf ball G on ball receiver 41a (102). If iron button 72 is not pressed and microswitch 45 is closed, control unit E sends a drive signal to motor 52 (103). Shaft 52a rotates, causing crank 53 and crank arm 54 to swing set arm 41 from a ball receiving position, shown in FIG. 4B, to a tee position, shown in FIG. 5.

When set arm 41 is in the tee position, detector plate 53a is detected by photo sensor 55 (104). Motor 52 is stopped. Stopper plate 41e pushes backward on the row of golf balls G that are pressing against the foremost golf ball G, thus allowing the foremost golf ball G to roll down set arm 41 to ball supplier 41c and be placed on tee 63. Proper placement of golf ball G on tee 63 is assured by magnet 48, which firmly positions set arm 41 as shown in FIG. 8. Micro switch 45 is opened as golf ball G leaves ball receiver 41a (105). Control unit E sends a drive signal to motor 32 causing it to rotate crank 33 (106). This pulls crank arm 34 down to pivot chute 22 clockwise on pivot 21a, as shown in FIG. 6. With chute 22 raised to a horizontal position, gate 22b is closed by stopper plate 44, thus preventing the next golf ball G from dropping into ball receiver 41a. This allows set arm 41 to be returned to its receiving position without interference from a golf ball G.

As motor 32 continues to rotate, chute 22 is pivoted counterclockwise. At the same time, bar 37 pivots around pin 36a and is lifted into the stack of golf balls G to prevent any clogging. In addition the clockwise and counterclockwise motion of chute 22 causes cam 38 to move sliding rail 23 back and forth to further prevent any stoppage in the flow of golf balls G along chute 22. When photo sensor 39 detects a half revolution of crank 33, motor 32 is stopped at its start position (107).

When infra-red sensor 46 (shown on FIG. 6) detects a golf ball G on tee 63 (108), control unit E drives motor 52 (109) to return set arm 41 to its receive position. When photo sensor 55 detects detector plate 53a (110) at half revolution of crank arm 54, indicating that set arm 41 is back in its receive position, as shown in FIG. 7, the cycle is completed (111).

After the golf ball G on tee 63 is driven, infra-red sensor 46 senses that golf ball G is not on tee 63 and the operating sequence is repeated until the number of golf balls G set into card reader 71 is used up.

After a pre-paid card is inserted in card reader 71, if iron button 72 is pressed (101) and microswitch 45 is closed by a golf ball G (112) on ball receiver 41a, as shown in FIG. 2B, control unit E sends a drive signal to motor 32 (113). Motor 32 rotates crank 33, causing chute 22 to pivot clockwise and counterclockwise until photo sensor 39, shown in FIG. 3C, senses that crank 33 has completed one revolution (114). With set arm 41 maintained in the receiving position, as shown in FIG. 9, golf ball G is rolled along set arm 41 and drops through ball supplier 41c to ramp 20a to roll onto shot mat 62 as shown in FIG. 1. This procedure can be repeated up to five times in this embodiment of the invention or up to the number n, set into card reader 71 (115 and 116).

Referring now to FIGS. 12A and 12B, there is shown a second embodiment of the present invention using a set arm 80. In this embodiment, a lead portion 80a, that may be formed from a material such as a polycarbonate, includes a guide rail 81, that terminates at a first end with a "U"-shaped ball supplier 82, and at a second end in a spade shaped joint 83. The upper surface of guide rail 81 is convex, as shown in FIG. 12D, to form a guide path for golf balls G. A hook 84 is attached to a bottom surface of guide rail 81 at a position near the first end. A reinforcer 85 on the bottom surface of guide rail 81 is at the second end to strengthen the structure.

A base 80b of set arm 80 includes a holder 86, that may be formed from any convenient material such as, for example, a polycarbonate. Base 80b is supported by a metal plate board 87. Holder 86 includes a hollow chamber 86b, into which joint 83 of guide rail 81 may be inserted. A pair of protrusions 86a on inner side surfaces of hollow chamber 86b hold joint 83 removably in place. FIG. 12c is a cross sectional view of hollow chamber 86b. Board 87 is affixed to an under side of holder 86 to provide a means for stringing a resilient band 80c, such as a spring, loosely between board 87 and hook 84.

In use, should lead portion 80a be struck by a golf club, it separates from base 80b without damage. Band 80c prevents lead portion 80a from being driven far from dispenser 100. The operation of dispenser 100 using this embodiment is as previously described.

Referring to FIGS. 13A, 13B, and 13C there is shown an embodiment of the present invention where a mat unit 60 is attached to a mat attachment 25b on enclosure 25. A plurality of pins 60a and a pair of protrusions 60b engage holes 61a and recesses 61b, respectively, of base mat 61. As can be seen in FIG. 13b, a hole 61c in base mat 61 receives a tee base 64. Tee 63 is secured to tee base 64. Shot mat 62 covers base mat 61 as shown in FIG. 13C.

In still another embodiment of the invention, it is possible to use the invention with manual feed of golf balls G without a card reader. In this case, a stacking unit is not used. The user places a number of golf balls directly on a chute and the dispenser then tees them one at a time as described previously.

Having described the preferred embodiment os the invention with reference to the accompanying drawings, it is to be understood that the invention is not limited to those precise embodiments, and that various changes and modifications may be affected therein by one skilled in the art without departing from the scope or spirit of the invention as defined in the appended claims.
