GOLF BALL DRIVING DEVICE
ABSTRACT OF THE DISCLOSURE

A golf ball driving device is disclosed, being a device which is mounted on wheels for easy manoeuvreability, and having generally an operating and transport handle, and a trigger release handle. The operating handle has a cam and ratchet at its lower end, for driving a ratchet bar against a compression spring (or pneumatic cylinder) to create compression force. The trigger release handle has a follower arm which latches against the ratchet bar, and it is moveable to release the ratchet bar and thereby to release the compression force. A striker plate moves forwardly and downwardly upon release of the compression, to strike a golf ball when in place. The striker plate is rotatably adjustable so that its angle and point of impact against a golf ball may be adjusted.

Description

~IcLD ~F T't~ I~V~NTI~:
This invention relates to a golf ball clrivin~ device, an~
particularly a co.npression operated device whose striking force comes from the release of stored energy. ~iore specifically, the presenL invention relates to a golf ball driving device which can ~e manoeuvreed around an ordinary golf course, duplicatin~ all or nearly all golf strokes normally taken during any normal play of that game.

1~ BACKGROU~D OF THE INV~NTIO~:
As is well known, the usual manner of playing the gaine of ~olf is wit~ a variety of clubs, both woods and" irons, and a putter. Very often, players -- at least those of more advanced rankin~ -- may carry special purpose clubs, so that the number of clubs being carried by a player, especially an advanced player, becornes considerable. So, also, the cost of acquiring and main.aining such a collection of clubs becomes considerable; ancl, o~ course, the weight of such a large collection of clubs becomes g.eater.
There are certain persons who, for a variety of reasons, may wish to partake of the exercise, fresh air, good ~eather and companionship that a golf game may usually ~fford, but for a variety of reasons can not or are not able to do so. Such persons may include physically handicapped persons or all kinds, as well as persons of advanced age WllO have not before .
learned to play the gsMe o~ golf.
27 ~oreover, there may be skilled players or novice players .' 1 ~

who wish for a clifferen~ challenge in respect o~ their ~ame, or who ~re becominv less capabl~ of carrying a heavy load of golf clubs durin~ a game, but for whom riding in an electric golf cart or hiring a caddy may not be acceptable.
In any event, the present invention seeks to provide a novel golf ball driving device for use by skilled or unskilled players, on regulation or championship courses as well as shorter courses. However, although as will be understood hereafter, the present invention will duplicate virtually all kinds of golf shots required durin~ a normal or even extremely difficult game of golf, it is not generally supposed that the device of the present invention would be used on a putting green -- where normally the rules preclude any machine or other device on the ~reen except a putter. That is to say, the ; present invention provides a golf ball driving device which will duplicate tee shots, shots from the rough, approach shots, etc.; and is particularly useful in making shots from beneath low hanging trees, which sllots are otherwise quite difficult to rnake. ~loreover, the present invention provides a ~0 device which is sufficiently adjustable that the range and trajectory of the golf ball, for each shot taken, may be closely controlled and duplicated from shot to shot.
There have been a nurnber of golf ball driving devices taught in the prior art, and other devices for miniature golf -~ garnes and the li~e; and there are a number of spring operated - catapults or throwing devices which are more particularly 27 desi~ned for use in throwing baseballs or footballs.
,: .
For example, one of the earlier known golf ball drivino . . .
~., ; 2 , '`' ~15~036 devices ;s tl~at t~hich iS t~ught in IJnited States ~atent

2,477,30~ issued July 26, 1949 by l~. A. tlALl~AN. That device, however, is a quite cumbersome device, re~uirin~ the use of both h~n~s and at least one foot in steadying and operating it.
Essentially, the i~lALKAN device is one which has a reciprocatin~
plunger driving a rack and in turn a rotatable gear to which an ann having an adjustable driving hea~ with a pair of striking faces, is secured. The force of the stri~ing motion of the striking head against a golf~ball is determined by the force by which the pllmger is manually operated, all of which ma~ requirè a certain physical distortion and discomfort to the operator.
R. E. LE, in United States Patent 3,410,258 issued Nove~ber 12, 1968, provides a centrifugal ball propellin~
device which ta~es several different ~orms or embodiments, but which requires the operation of a plunger to affect the distance and trajectory o~ the ball when it is "thrown" from the device.
H. E. LIPP~RT, has provided a variety of types of apparatus, mainly spring loaded, intended for playing miniature golf, whereby the player sights a device which has the appearance of a gun in the direction of intended play. Such devices are taught in his United States Patents 3,4~9,84~, dated September 30, 196~; and three patents issued August 10, 1971, ~umbers 3,5g~,411, ..2, and ..3.
Several other spring loaded ball throwing or catapult 27 machin2s include DI~O~, United States Patent 3,~51,1~5, issued April 20, 197~, which shows a device intende~ for tihro~ing , .

footballs; ~ Y, Unite~ ates ~'~ten~ 4,V~,07~, issued t~pril 73, ~;liCIl ~.ovides a spring loacled device for pitchin~ a i~aseball; and a toy c:~apult device shown in ~IASHI~iOTV, United States Patent ~,111,179, issued Septmeber 5, 1978.
The latter patent, HASHI`IOTO, shows a vertically moving pivot arrn~hich has a plurality of notches on its underside, the notches being adapted to accom;nodate an elastic band mounted in a yo~e, at a variety of heights, so as to efrect the catapultin~ force and therefore the-range of the ~rojectile to be thrown by the toy.
None of the above prior art, however, teaches a device of the present nature, which is specifically intended for duplicating the variety o~ golf shots normally taken durin~ an ordinary round of golf on a standar~ golf course; including tee shots which may have a range of up to three hundred yards,-an~ approach shots which may have a range of only ten or twenty yards. As well, the ~resent invention provides a device by which the trajectory of the ball inay be varied, so as to shoot up.lill or downhill, or over a hedge or other o~stacle, etc.
Accordin~ly, the present invention provides a golf ball driving device which has a frame and wheels mounted to the frame, and at least one support means for the frame when the device is at rest. T'ne golf ball driving device has compression means, means for compressing the compression Means, : and means for releasing the con~pression means. A striker plate is provide~, in SUCll a manne. that the motion of the striker 27 plate generally descri~es a downwardly and ~orwardly directed arc, the lowest point of that arcuate motion being at a ~osi~iQ~ e~ e com1)ressioT~Illealls h;ls its least compression.
.~ccording to ~l~e rresent inventioll, a driving ratcllet and cam are associated ~ith a ~lriveable ratcllet l~ar, for co.npressin~
the compression means; and are Moveable out of en~agement witl-the ratchet bar ~hen requil-e(l. The means for releasing the compression means -- the trigger -- has a follower ar~ in contact with the ratchet bar, and which is ~isengageable therefrom. ~5andle means, such as a lever arrn, are provided for driving the cam and ratchet means so as to compress the 10 compression means; and other lever arm or handle means are provided for moving the follower arm out of contact with the ratcnet ~ar.
Thus, the present invention provides a ~olf ball driving device w'nich is of relatively sirnple manufacture and assembly, and inexpensive in cost.
~urther, the present invention provides a device of quite reasonable appearance, to which may be appended storage means for carrying golf balls and tees, and other golf-related accessories, refres'lments and the like.
Still further, the present invention provides a golf ball driving device w'nich essentially duplicates all norrnal golf strokes; but it is recognized that the device of the present invention would not normally be used for putting strokes because of a general prohibition against the use of such devices on the ,,reens of rnost golf courses.
Still further, the present invention has an object of 27 providing all of the above in such a manner that considerable sportirlg challenge is still maintained, consistent witll the purposes o~ tllc g-ame of vol1, ~)ut ~y wllic~ less dalna~e to a co~rsc occurs because ~mintentional clivots are not taken.
L~loreover, by usin~> a levice of the >resen~ invention, the player can generally shor~ell t'~ie aillo~m~ oE time taken, because of consistency an~ therefore a lessenecl chance of loosing balls due to inadvertent slicing or hookin~, and ~ecause less time is taken for eacll tee or fairway stro.~e because the device can be coclced and ready to take the stroke ~hile the player is waiting for another player to make his stroke.

G

D~s~LPrIo~ r~ R~D r.iii~)DI~I~.NTS:
i The golf ball ~Irivin~ ~levice of the present invention is shown ~en2rally ~t lO in Fi~,ure 1, an~ in t'l~at Ligure the device 1~ is shown beIIin~ but not yet in driving relationship to a golr ball 12. As will be seen from the description that follows~ tlle volf ball 12 may be placed on a tee or played from the fairway -- or, indeed ? from sand or pebble -- just as it would be and according to the general rules of the game of golf. The workin~ mechanism of the`device is within the body portion or ca~inet 14; and in the devLce shown~ two poclcets or receptacles 16 are shown, each having a hinged lid 18, one on either side of the .~evice. Golf balls and tees, other accessories, refreshments, etc., may be Icept in the receptacles The device has a pair of wheels 20, one at either side, and when at rest there is at least one and generally a pair of supports 22, one at either side of the body portion 14. The support 22 may comprise a small plate as shown, or a spur which .nay extend downwardly into the gro~md for a short distance.
As seen in Figure 1, there are two handles for t~e device, desi~7nated at 24 and 26. The handle 24 serves two purposes, both as an operating handle whereby the co~pression means within the device is compressed, and as a manoeuvreing or transport h~ndle by which the device is moved from place to place. Obviously, it is a simple matter to tilt the handle 24 bac~cwards beyond its own limit of travel, so that the device 27 lifts off its s-upports 2Z at the front end, whereby it is then llS1036 moveable on its wheels 20. Lining the device up behind a golf ball 12 is a simple matter; and when the striker plate shown generally at 28 is in its cocXed position as described hereafter, particularly with reference to Figure 4, the exact positioning of the device 10 to the ball 12 may be determined by iooking downward through a sighting opening 30 in the top of the body portion 14.
-; Turning now to Figure 2, the principal - operating components of a golf ball driving device according to the `present invention are shown, in an unstressed or-rest position.
~; Generally, the device comprises a pair of upper frame members ~32, one at each side, and a pair of lower frame members 34.
The wheels 20 are conveniently mounted for rotation about an axle 36, supported by a pair of frame members 38.
The front support 22 is found at the bottom of a front frame member 33; so that, in general, the frame of the golf ball driving device of the present invention comprises members . , -32, 33 and 34 on each side.
~ - Within the housing 14, there is a compression means 40, normally a sprin~ which is shown to be a coil spring, and which - ~ may comprise a pair of coil springs, or alternatively the `compression means may comprise a pneumatic cylinder.
Conveniently, the spring 40 has a pair of end plates 42, to which are secured a pair of ~ounting brackets 44. The top mounting brackets 44 are secured at 46 which is an axle about which the top of the spring 40 is there~y rotatably mounted.
. ~ . . .
27 As will be seen hereafter, the handle 24 is also rotatably mounted at the axle 46; and by that means, each of the springs ~ ~ , .

4~ and the handle 24 are rotatably mounted or secured to the frame of the golf ball driving device.
The lower bracket 44 of the spring 40 is pivotally mounted at 4~ to a striker arm 50. Conveniently, the striker arm 5 comprises a pair of such arms, as indicated in Figure 3. The striker arm 50 is pivotably secured to the upper frame member 32 at 51, so that an axle 51 extends between the two upper frame members 32 at each side of the body of the device, with the pair of arms 5U pivotably mounted thereto.
In any event, it is seen that the striker plate 28 is pivotably secured at 52 to the bottom end of the striker arm 50. Moreover, a bracket 53 is provided, to which a ratchet arm 54 described in greater detail herea~er is pivotably secured at 56.
The ratchet bar 54 is, as noted, secured at its bottom end to the striker bar 50 by bracket 53, at 56. The upper end of the ratchet bar 54 moves freely through a pair of box members 58, secured at the rear ends of the upper frame members 32.
(See Figures 6 and 7.~ The upper side of the ratchet bar 54 has a sawtooth configuration formed in it, as at 6U; and the sawtooth configuration extends substantially along the entire upper length of the ratchet bar 54.
A cam 62 and ratchet 64 are adapted to the bottom end of the operating handle 24, which comprises a lever arm rotatably mounted to the frame of the device at 46. The cam 62 is forced downwardly towards ~he ratchet bar 54 by a spring 66, so that - 27 the ratchet 64 normally maintains contact in any one of the notches in the sawtooth 60. The shape and positioning of the llS1036 ratchet 64 Witl1 respect to the ratchet bar 54 are such that, when the oper~ting arm is ~oved forwar~ (to the le~t in Figure 2) the ratchet 64 enga~es with one of the sawteeth 60 of the ratchet ~ar ~4, causing the ratchet bar to move upwardly to the right, through the box frames mernbers 58. In so doing, the stri~.cer arm 50 is pulled backwardly, and the spring 40 `is compressed. A number of such operations may be conducted, according to the compression of the spring 40 as may be determined, and discussed in greater detaii hereafter.
lO Obviously, on each return stroke of the operating handle 24 rearwards -- to the right as shown in Figure 2--- the ratchet 64 rides upwards over each succeeding sawtooth 60, until the backward motion of the operating arm 24 stops or until the cam 62 lifts away from the ratchet bar 54 as discussed hereafter.
Also associated witl1 the box members 58 through which the rear upper end OL ratchet bar 54 is free to move, is a follower arm 5~ which contacts t'ne sawteeth 60. The follower arm 68 may act by ~ravity against the ratchet bar 54, or it may be biassed by a spring 70. The follower arm 68 is pivotably mounted at 72 to the rearmost handle or arm 26.
As the ratchet bar 54 is moved rearwardly by operation of the operating handle 24, thereby compressing the spring 40, the follower arm 50 engages with succeeding sawteeth 60, and is held against them by gravity, or is spring biassed tension against the~ by the spring 70.
Obviously, as the compression in the spring 40 increases, ~ 21 its tendency to expand to its original position increases, thereby creating a locking tendency of the follower arm 6~ in ~ ~51036 one oî the spaces between the sawteettl ~ of the ratchet bar 54, against the backside of the box member 5~. Thus, the compression of the spring 40 maintains the follower arm 6~ in locked position.
It is evident, therefore, that the follower arm 6~ and handle 26 function together as a trigger or release for the golf ball driving device of the present invention, so that release of the driving force of the device may be determined upon movement of the handle 26.
However, before the triggering action by release of the follower arm 6~ can occur, it is necessary to disen~age the ratchet 64 from the ratchet bar 54. This is accomplished by further backwards motion of the handle 24, more specifically as indicated in Figure 4.
Referring also to Figures 3 and 4, as well as Figure 2, it is now seen that operation of the golf ball driving device is very simple, requiring first a compressing of the spring 40 by way of operation of the handle 24, followed by disengagement of the driving ratchet 64 from the ratchet bar 54, and thereafter followed by disengagement of the follower arm ~8 from the ratchet bar 54, which constitutes a triggering action for operation of the device.
In general, the device 10 is placed substantially in position before the compression means 40 is cocked by operation of the handle 24. Thus, during movement of the device 10 by manoeuvering the same using handle 24, the compression means is 27 uncompressed; thereby saving unnecessary wear and tear on the device, as well as being more safe for the operator or his playing companions.
The golr ball 12 is nor~ally located between the support members 22, and Inay be more or less forward of a line drawn between the members 22, dependin~ upon the stroke to be taken and the intende~ range and trajectory of the ball 12 as it is driven. The range is determined by the amount of compression of the spring 40, which may be indicated on a scale conveniently placed on the ratchet bar 54 at 74. Obviously, the more compression there is in the spring 40, the greater will be the impact of the striker plate 2~ against the ball 12, and the greater the range.
The trajectory of the ball 12 is a function of the force by which it is hit, but it is also a function of the angle at which impact against the ball 12 is made by the str ker plate 28. Thus, the stri'icer plate 28 is pivotably mounted at 52 to .he stril~er arm 50, in such a manner that as the angle of the striker plate 2~ is increased with respect to the vertical when at rest, as indicated in chain-line in ~igure 2, the point at which the striker plate will impact the ball 12 becomes lower, ana the face of the striXer plate 28 is less steeply inclined to the ground. This is the same as the face of various golf clubs, both woods and irons, where the face of a 2-iron, for example, is considerably more vertical than the face of, say, a 9-iron. Like~ise, the face of a driver or l-wood is consideLably ~ore verticaL than the face of a 4-wood.
It is desireable, however, to fix the striXer plate 28 in ~ ~ .
27 place for any given strol~e which is about to be taken. For that purpose, therefore, a strilcer plate adjustment arm 7~ is ~151036 provided, which may co-operate with a stu~ 78, to lock the rotatable adjustment of the striker plate 28 in any given position. That co-operation is generally by means of a number of holes which are formed through the striker plate adjustment arm 7~, through any of which the stud 78 may extend.
Obviously, the strike~ plate adjustment arm 76 has a springiness to assure a secure co-operation with the stud 78, as indicated by chaln-line in Figure 2.
Also, it is clear tha. the axis about which the rotatable adjustment of the stri~er plate 28 is accomplished is an -axis which is perpendicular to the direction of movement of the striker plate. .loreover, since the striker plate is located at the bottom of the- striker arms 50, upon release of the compression force in the- spring 40, it is clear that the ~ovement of the striker plate 28 is such that it describes an arc. Further, the lowest portion of that arc is at a position - when the compression in the spring 40 is at its lowest point --generally nil.
The forward motion of the striker arms 50 carries the striker plate 28 through the rest position of the ball 12, thereby providing followthrough for proper guidance of the ball following impact. However, it is not necessary for there to be very much followthrough, and a shock absorber 80 is provided to stop the forward motion of the striker arm 50 and to absorb some of the energy of that forward motion. Other of the energy o~ the forward motion is absorbed by the spring 40, .. , -, .
27 which by now is in tension, and restoration of the striker arm 50 and the compression components including the ratchet bar 54 to their rest position, is t~ereby assure~.
~ igures 5, 5 and 7 are provided to demonstrate the relationship of t`ne ratchet bar 54 to the fra~e and to the box members 50. Thus, for ex~mple, it may be seen that the drive cam ~2 ~enerally comprises a pair of arms, between which the ratchet member 64 is located. Also, the relationship of the follower arm o8 to the box mem~er 58 is shown in Figure 7, and from Figures 6 and 7, it is clear that the ratchet bar 54 is unhindere~ except for the follower arm S8 in either backward or ~orward motion relative to the box member 58.
A golf ball driving device has been described, which has sufficient adjustability both as to the co~pression in the sprin~ means and the angle of impact of the striker plate against the ball, so that the range an~ trajectory of the golf ; ball when driven, can be controlled. ~loreover, it is evident that because of the placement of the striker plate within the device, there is no unecessary and damaging taking of divots from the fairway as a golf ball is being driven. It is also apparent that the height of the point of i~pact can be determined and adj71sted, so that the point of impact on a tee shot ~ould be considerably different than the point of impact on a simple approach shot or a shot taken from a sand trap.
2~1oreover, the force of the impact is controlled.
Obviously, the golf ball driving device of the present invention can be adjusted as to the compression of the spring be~ore the player is aLlowed to ta7~e his shot, thereby saving ~ - 27 time. ~loreover, since the ~olf ball driving device of the present invention will neither slice nor hoot~ a golf ball upon 115~036 impac~, less ti~,ne for play shoulcl be ta~en, because less Cime would ~e spent looking for an otherwise lost ball.
T'~e materials of which the present invention may be made inclu~e steel and aluminum, or plastic sheeting for the housing, so that assem~ly of the golf ball driving device of the present invention is easily and inexpensively accomplished.
As mentioned, the compression spring 40 may comprise a pair of springs, or a pneumatic cyllnder. T'ne triggerin arrangement of the follower ar~ against the ratchet ~ar may be gravity located, especially in view of the spring force of the spring when in compression.
Other features and alterations to the invention may also be made, without departing from the spirit and scope of the appended claims.
