BACKGROUND AND SUMMARY OF THE INVENTION

The invention relates to golf practice devices and in particular to a golf practice apparatus directed to chipping a ball onto a target area as part of a practice game suitable for indoor or outdoor use.

Golf practice devices suitable for indoor or outdoor use have been designed to test and improve a golfer's technique. Some of the practice devices function as indoor driving ranges. Others, such as miniature golf courses, function as putting ranges. Still others provide a chip and putt game, such as that shown in U.S. Pat. No. 4,336,939. U.S. Pat. No. 3,826,501 simulates a driving range, bunkers, greens, etc. Other patents disclosing various types of golf games or practice devices include U.S. Pat. Nos. Des. 83,498, Des. 234,526, Des. 239,299 and 4,018,436.

Chip shots are a particularly challenging part of the game of golf. As with other shots in golf, a player can improve his or her game by chipping with a high degree of accuracy. It would be advantageous to have a golf practice apparatus which is both challenging and interesting to the user and helps improve the accuracy of a golfer's chip shots.

It is therefore an object of the present invention to provide a golf chipping practice apparatus which is relatively compact and thus suitable for indoor or outdoor use and which provides simulated chipping practice for the user.

It is a further object of the invention to provide a golf chipping practice apparatus on which a challenging and interesting golf chipping game is played, the game being suitable for individual play as well as match play against an opponent.

Accordingly, a golf chipping practice apparatus is provided for use by a player who is positioned in a ball hitting area of the apparatus. The apparatus comprises a ball receiving area onto which balls are chipped. The ball receiving area is divided into a plurality of target zones and further includes a plurality of regions, each of which encompasses a predetermined number of the target zones. A plurality of sensors are provided in the ball receiving area for detecting which target zone a ball lands in. And a scorekeeping device is provided which is responsive to the sensors for determining the target zone a ball lands in. The scorekeeping device also, simultaneously, counts the number of balls landing in each region of the ball receiving area. As such, both the target zone information and the number of balls landing in each region are available for scoring a game.

In the embodiment described below, the scorekeeping device automatically records both a total score, based on the target zones balls land in, and a count of the number of balls landing in each region of the ball receiving area. A round or game is completed when a predetermined number of balls have been chipped into each region of the ball receiving area.

The apparatus described below comprises a plurality of panels supported forward of the ball hitting area at which the player aims chip shots. Each panel forms one region of the ball receiving area of the apparatus. A plurality of target zones are provided on each of the panels. A plurality of sensors associated with each of the panels are used to detect the target zone a ball has landed on. The scorekeeping device generates and maintains a total score for each round of play.

Additional features of the preferred scorekeeping system of the invention include a device for accumulating a panel count for each panel, the panel count equalling the total number of balls landing on each panel. The panel count, which is used to determine the end of a round of play, is independent of the total score maintained by the scorekeeping device. The game played on the apparatus of the present invention is structured to challenge a golfer/user to direct chip shots to each of the aforementioned panels at least a predetermined minimum number of times as measured by the panel count. Aiming skill is tested by penalizing the player who hits more shots than the minimum required on any given panel, the penalty being the accumulation of additional total score for each extra shot taken. As in regular golf, a lower total score is desirable.

In the preferred embodiment, the invention incorporates three separate panels, termed Par 3, Par 4 and Par 5, and at least five target zones on each panel, termed eagle, birdie, par, bogey and double bogey (in order of ascending scoring value). The scorekeeping device accumulates the total score for each player or each game round and requires the player to aim for and hit several different targets throughout the course of a game. The player shooting the round with the lowest scoring value wins. Thus, the game encourages players to chip with high accuracy.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

Referring to FIG. 1, a golf chipping practice apparatus 10 is provided in accordance with the present invention. Apparatus 10 includes a ball hitting area 12 where a player stands when using the apparatus. A golf ball is positioned on a teeing pad 14 formed, for example, of artificial grass or another suitable material, to stimulate conditions from which chip shots are made. A frame 16 supports a plurality of panels 18, 20 and 22 in a ball receiving region forward of the ball hitting area 12. The ball receiving region means the region toward which a player chips a ball. In the apparatus of the present invention the ball receiving region is the surface area of panels 18, 20, 22, which are raised on frame 16 above ball hitting area 12. Panels 18, 20, 22 are preferably each 8-feet by 8-feet in size.

Panels 18, 20 and 22 are generally rectangular in shape, solidly constructed of plywood or the like and arranged on frame 16 generally co-linearly, one after another, along a longitudinal axis 24. The longitudinal axis extends generally along the centerline of each panel and through or above the teeing pad 14 of ball hitting area 12. Frame 16 may conveniently be formed in separate sections, one for each panel 18, 20, 22, and may be fabricated to collapse for portability, if desired.

The top surface of each panel 18, 20, 22 is covered with artificial turf, carpeting, or another material which simulates a green on a golf course. The appearance of the surface of each panel can be enhanced by markings 26 in the shape of simulated greens or the like.

Each of the panels 18, 20, 22 is supported on frame 16 inclined from the horizontal generally toward ball hitting area 12. Thus, the near edge 28 of panel 18 is lower than the far edge 30, so that a ball landing on panel 18 will tend to roll toward ball hitting area 12. Similarly, near edge 32 of panel 20 is lower than far edge 34 and near edge 36 of panel 22 is lower than far edge 38. The panels are supported at gradually ascending elevations, with the rear or most distant panel 22 (measured from ball hitting area 12) at a higher overall elevation than the others and the panel 18 closest to the ball hitting area at a lower elevation than the others. Each panel may alternatively be supported on frame 16 at approximately the same average level as the other panels, if desired. The incline or pitch of each individual panel may also vary from one to another, for example, increasing with distance from the ball hitting area.

The panels are supported spaced-apart from one another. For example, far edge 30 of panel 18 is spaced-apart from near edge 32 of adjacent panel 20. The adjacent edges 30 and 32 of adjacent panels are also at different levels, with far edge 30 of panel 18 supported at a higher level than near edge 32 of adjacent panel 20. Likewise, far edge 34 of panel 20 is spaced-apart from near edge 36 of adjacent panel 22 and edge 34 is at a higher level than edge 36. The panel surfaces thus form a broken saw-tooth type of pattern. The spacing and different levels of the panel edges help prevent golf balls landing on one panel from rolling down onto the adjacent panel.

Side screens or netting 40, supported on frame 16, extends above panels 18, 20, 22 along their respective side edges. The netting is somewhat schematic, as shown in FIG. 1, and in actual installation might extend outwardly at an angle from the side edges of the panels and at the far end of the apparatus in order to catch balls which miss the panels entirely. Alternatively, netting 40 might be eliminated altogether in installations where panels 18, 20, 22 are surrounded by walls or curtains supported by an enclosing structure (not shown). It will be appreciated by those skilled in the art that netting 40 is designed to collect or confine stray balls.

A ball return system, described in greater detail below, is partially indicated in FIG. 1 by a ball return chute 42 and collection tray 44 adjacent ball hitting area 12. Balls hit onto panels 18, 20, 22 are returned via the ball return system to tray 44, preferably by gravity, in order to facilitate continuous play by the user. A scorekeeping stand 46 is provided adjacent ball hitting area 12 and includes scoring displays and necessary switches or other means for turning on and off or resetting the apparatus from a location adjacent the ball hitting area. An additional score board 48 can be installed at the far end of the apparatus, if desired.

Each panel 18, 20, 22 includes on its upper surface one or more holes, 3-to 4-inches in diameter, which extend through the panels and serve as targets for the chipping game played with the apparatus. Panel 18 includes holes 52 and 54. Hole 52 on panel 18 is farthest from ball hitting area 12 and 3-inches in diameter and hole 54 is closest to ball hitting area 12 and 4-inches in diameter. Panel 20 includes holes 56 and 60. Hole 56 on panel 20 is farthest from ball hitting area 12 and 3-inches in diameter and hole 60 is closest to ball hitting area 12 and 4-inches in diameter. Panel 22 includes holes 62 and 64. Hole 62 on panel 22 is farthest from ball hitting area 12 and 3-inches in diameter and hole 64 is closest to ball hitting area 12 and 4-inches in diameter.

FIG. 2 shows parts of the ball return system supported beneath panels 18, 20, 22, the panels being outlined in phantom. Ball return system 50 includes a series of channels, tubes, gutters, troughs or the like which convey and return by gravity balls to ball hitting area 12 from panels 18, 20 or 22. Balls enter ball return system 50 through various means which include sensors incorporated into the scoring system of the present invention, as described below.

Ball return system 50 includes a central elongated longitudinal gutter 66 extending lengthwise beneath each of the panels 18, 20 and 22, generally along and parallel to longitudinal axis 24. In the preferred embodiment of the golf chipping apparatus, target holes 52, 54, 56, 60, 62 and 64, which are designed to receive balls therein, are all slightly offset from the central longitudinal axis 24 of the apparatus. Consequently, short side gutters extend perpendicularly from central gutter 66 and balls passing through the holes drop into the side gutters. The side gutters generally extend transverse to the direction of longitudinal axis 24 a distance necessary to intercept and collect balls falling through the target holes. Under panel 18, side gutter 70 extends beneath hole 52 and side gutter 72 extends beneath hole 54. Under panel 20, side gutter 74 extends beneath hole 56 and side gutter 76 extends beneath hole 60. Under panel 22, side gutter 78 extends beneath hole 62 and side gutter 80 extends beneath hole 64.

An additional system which feeds balls into central gutter 66 includes three ball return channels, one associated with each of the panels 18, 20 and 22. Each of the ball return channels extends along at least one edge of each of the panels, that edge being the lowest edge, in order to catch and collect balls from the panel. Each of the panels is inclined generally in the direction of the ball return channel associated with that panel. The arrangement cf panels is such that a ball landing on any of the target panels of the apparatus 18, 20, 22 will be directed, by the incline of the respective panel on which the ball lands, into one of the ball return channels 82, 84, 86.

Ball return channel 82 extends generally perpendicularly to longitudinal axis 24, along edge 28 of panel 18, the lower edge of the panel closest to ball hitting area 12. Channel 82 extends the length of edge 28 in order to catch all balls which land on panel 18, except for the balls which enter holes 52 and 54.

Ball return channel 84 extends generally perpendicularly to longitudinal axis 24 along edge 32 of panel 20, the lower edge of the panel closest to ball hitting area 12. Channel 84 extends the length of edge 32, in order to catch all balls which land on panel 20, except for the balls which enter holes 56 and 60.

Ball return channel 86 extends generally perpendicularly to longitudinal axis 24 along edge 36 of panel 22, the lower edge of the panel closest to ball hitting area 12. Channel 86 extends the length of edge 36 in order to catch all balls which land on panel 22, except for the balls which enter holes 62 and 64.

Referring to FIGS. 1, 2 and 3, a plurality of sensors are positioned at selected locations throughout the apparatus for the purpose of detecting or sensing where balls land on the apparatus. The sensors are located within ball return channels 82, 84 and 86 and within target holes 52, 54, 56, 60, 62 and 64. An alternative location for the sensors associated with each target hole on the apparatus is to locate the sensors in the short branch gutters 70, 72, 74, 76, 78 and 80 which extend beneath the holes. Each sensor is a pressure-sensitive switch of any conventional type which closes an electrical circuit when a ball passes over the switch. Other types of sensors designed to detect the passage of a golf ball over the sensor may alternatively be used. The arrangement of sensors on the apparatus, and the processing of the electrical signals received from the sensors, establishes the scoring system of a golf practice chipping game played on the apparatus.

Before defining the location of the sensors, a description will be provided of the overall object of the golf chipping practice game. The ball receiving area of the apparatus is divided into a plurality of separate regions for scorekeeping purposes. In the apparatus shown, three regions are provided in the form of the three panels 18, 20, 22. The panels are subdivided into a pattern of target zones which are assigned different scoring values. For example, each of the holes 52, 54, 56, 60, 62 and 64 is a target zone. Like in regular golf, balls which are chipped directly into or roll into a hole receive a favorable score. Balls which land on panels 18, 20 and 22 and do not enter any of the holes are assigned scores based on how close the ball lands to the center line of each panel.

The center line of each panel is generally at or near the longitudinal axis 24 of the apparatus. Balls landing closer to the center line receive more favorable scoring than balls landing farther away from the center line. Thus, the game is designed to favor accurate aiming of chip shots onto the panels by rewarding players whose balls land closest to the center of the panels, with the greatest scoring rewards given to shots which cause the ball to enter one of the holes.

The plurality of sensors positioned at various locations on the apparatus serve as a means for detecting which target zones a ball lands in each of the target zones of the apparatus. The sensors associated with each target hole, described above, detect the balls which enter the target zones formed by the holes. In order to detect the location of balls which land on the panels but do not enter one of the holes, a series of sensors is located in each of the ball return channels 82, 84, 86.

FIG. 3 shows ball return channel 82 in cross-section. Channel 82 is representative of the other ball return channels 84, 86. Channel 82 slopes downward toward the center of the channel, causing balls entering the channel at any point to roll toward the center, after which the ball passes into central gutter 66 for return to tray 44 in the ball hitting area 12. A first sensor 90 is located in the center of ball return channel 82, to detect all balls exiting the ball return channel into gutter 66.

A pair of additional sensors 92, 94 are located on the bottom of ball return channel 82, spaced a predetermined distance outwardly from the center of channel 82. Sensors 92 and 94 define target zone boundaries on opposite sides of the sensors. Balls which enter channel 82 in the region above sensor 92, to the left of sensor 92 as viewed in FIG. 3, will roll downhill over sensor 92 as they pass by gravity to the center of channel 82 and exit the channel. Balls which enter channel 82 below sensor 92, to the right of the sensor as viewed in FIG. 3, do not pass over sensor 92 as they exit the channel. Thus, sensor 92 establishes a zone boundary for balls entering the channel. Balls which enter the channel between sensor 92 and the left edge of channel 82 (as viewed in FIG. 3), at 96, will trip or energize sensor 92 (in addition to other sensors). Such balls will also trip sensor 90 as they exit the channel. Balls which enter channel 82 below or to the right of sensor 92 trip only sensor 90. Similarly, sensor 94 establishes a zone boundary for balls entering channel 82 above sensor 94, between sensor 94 and end wall 98. Such balls will trip sensor 94 as they roll downhill toward the center of the channel. Such balls will also trip sensor 90 as they exit the channel. Balls which enter the channel 82 below or to the left of sensor 94 will only trip sensor 90.

Two additional sensors, 100 and 102, are positioned in the bottom of channel 82. Sensor 100 is located a predetermined distance from the center of channel 82, between sensor 92 and the left edge 96 of channel 82, as viewed in FIG. 3. Sensor 100 forms a target zone boundary between balls which enter channel 82 in the region above sensor 100, to the left of sensor 100 as viewed in FIG. 3, and balls which enter channel 82 below sensor 100, to the right of sensor 100. Balls which enter the channel above sensor 100 will trip or energize sensor 100, followed by sensor 92, followed by sensor 90, before exiting the channel.

Sensor 102 is located a predetermined distance from the center of channel 82, between sensor 94 and the right edge 98 of channel 82. Sensor 102 defines a target zone boundary between balls which enter channel 82 in the region above sensor 102, to the right of sensor 102 as viewed in FIG. 3, and balls which enter channel 82 below sensor 102, to the left of sensor 102. Balls which enter channel 82 above sensor 102 will trip or energize sensor 102, followed by sensor 94, followed by sensor 90, before exiting the channel.

Sensors 90, 92, 94, 100 and 102 together define target zones on the adjacent panel above the ball return channel For channel 82, the adjacent panel associated with the ball return channel is panel 18. Balls which land on panel 18, except those which enter holes 52 or 54, roll downward into ball return channel 82 in one or another of the various zones established by sensors 90, 92, 94, 100 and 102. Referring to FIG. 3, the various target zones associated with panel 18, extending above ball return channel 82, are defined by the golfing terms par, bogey and double bogey.

The central target zone, extending along and on either side of the central longitudinal axis 24 of panel 18, is the par zone. The outer boundaries of the central or par target zone are defined by sensors 92 and 94 in channel 82. Balls landing within the par zone will roll down inclined panel 18 and fall into channel 82 in the region between sensors 92 and 94, tripping sensor 90 but not sensors 92 and 94 as the balls exit the channel. A ball which trips sensor 90 without tripping any of the other sensors in channel 82 will receive a "par" scoring value for the shot.

The region just outside the par target zone on panel 18 includes two parallel bogey target zones. The divisions between the par and bogey zones are indicated in FIG. 3 by zone boundary lines 104 and 106, extending above channel 82 onto adjacent panel 18, which is represented schematically in FIG. 3. The zone boundaries, which for panel 18 are also shown in FIG. 1, extend generally parallel to the central longitudinal axis of panel 18, between lower edge 28 and top edge 30. Balls landing in the region outside zone boundaries 104 and 106 will roll down panel 18 and drop into channel 82 above sensors 92 or 94, tripping one or the other of those sensors as they pass to the center of the channel. The balls subsequently will also trip central sensor 90 as they exit channel 82. Any ball which trips either sensor 92 or sensor 94 but not sensors 100 or 102, will receive a "bogey" scoring value for the shot.

The pair of regions located outward from the bogey zones, the outermost regions on panel 18, are a pair of parallel double bogey target zones. The division between the bogey and double bogey zones are indicated in FIG. 3 by zone boundary lines 108 and 110, extending above channel 82 onto panel 18. Those zone boundaries, also shown in FIG. 1, extend generally parallel to the central longitudinal axis 24 of panel 18, between lower edge 28 and top edge 30. Balls landing in the double bogey zones, between zone boundary 108 and edge 111 (FIG. 1) and between zone boundary 110 and edge 113, will drop into channel 82 above either sensor 100 or sensor 102. Balls passing over sensor 100 will subsequently trip sensors 92 and 90 as they exit channel 82. Balls passing over sensor 102 will subsequently trip sensors 94 and 90 as they exit channel 82. Any ball which trips either sensor 100 or sensor 102 will receive a "double bogey" scoring value for the shot.

Zone dividing lines 104, 106, 108 and 110 need not be indicated physically or by markings on the upper surface of panel 18, or the other panels, as players will quickly become aware of the approximate dividing lines of the regions. The sensors in ball return channel 82, in effect, define the target zone boundaries 104, 106, 108 and 110. A ball landing in one of the target zones, assuming it does not enter either hole 52 or hole 54, will eventually roll down into ball return channel 82 and trip the sensor or sensors associated with the target zone in which the ball landed As such, each target zone on a panel is defined as that part of the panel which directs balls to the sensor for the target zone. The double bogey zones on panel 18 are the areas of the panel which direct balls to either sensor 100 or sensor 102. The bogey zones on the panel are the areas which direct balls to either sensor 92 or sensor 94, without tripping sensors 100 and 102. The par zone is that area of panel 18 which directs balls landing on the panel to sensor 90, without tripping any of the other sensors in channel 82.

Ball return channel 84 includes sensors arranged exactly like those shown and described with reference to FIG. 3. Channel 84 defines target zones on panel 20 like those described above with reference to panel 18. Using the same reference numbers from FIGS. 1 and 3 for the zone boundary lines, panel 20 includes a par zone extending longitudinally down the center of panel 20 between zone boundaries 104 and 106. Panel 20 also includes a pair of parallel bogey zones between boundaries 108 and 104 on one side of the par zone and between boundaries 106 and 110 on the other side of the par zone. Panel 20 further includes a pair of parallel double bogey zones lying outside zone boundaries 108 and 110.

Ball return channel 86 includes sensors exactly like those shown in FIG. 3. Channel 86 defines target zones on panel 22 like those described above with reference to panel 18. Using the same reference numbers from FIGS. 1 and 3 for the zone boundary lines, panel 22 includes a par zone extending longitudinally down the center of panel 20 between zone boundaries 104 and 106. Panel 22 also includes a pair of parallel bogey zones between boundaries 108 and 104 on one side of the par zone and between boundaries 106 and 110 on the other side of the par zone. Panel 22 further includes a pair of parallel double bogey zones lying outside zone boundaries 108 and 110.

Thus, a plurality of sensors associated with each panel 18, 20, 22 serve as a means for detecting when a ball has landed on each individual target zone on each panel. A ball landing anywhere on any panel, or even a ball landing directly in one of the ball return channels 82, 84 and 86, lands in a target zone of one scoring value or another. The sensors in channels 82, 84 and 86, and in each of the target holes, together form a means for detecting a ball landing on each of the target zones of the apparatus.

The apparatus also includes a scorekeeping device responsive to the sensors for determining the target zone a ball lands in. From the information about the target zone a ball lands in, a scoring value can be assigned to the shot. The conversion of electrical signals received from the various sensors on the apparatus into a score for the golf chipping game associated with the apparatus is described with reference to FIGS. 4 and 5.

Referring to FIG. 4, a schematic representative of a scoring system is shown for a golf chipping practice game played on the apparatus of the present invention. Rectangles 18, 20 and 22 correspond to the three panels shown in FIG. 1, viewed from above. The panels are arbitrarily assigned a par number associated with the distance of the panel from the golfer. Panel 18 is designated the Par 3 panel, panel 20 is designated the Par 4 panel and panel 22 is designated the Par 5 panel. The target zones on each panel described above with reference to FIGS. 1 and 2 are depicted schematically in FIG. 4.

Panel 18 includes the two holes 52, 54, which are called eagle and birdie target zones, plus the three target zones, par, bogey and double bogey, discussed above with reference to FIG. 3. Ball return channel 82 at the bottom of panel 18 is depicted as a series of rectangles and a central circle along the bottom edge of the panel. The rectangles are schematic representations of sensors 92, 94, 100 and 102 for detecting the passage of golf balls at different locations in ball return channel 82. The circle 90 corresponds to the sensor at the base of ball return channel 82, where a ball exits the channel and enters central gutter 66 (FIG. 2). Rectangle 18 thus schematically represents the various target divisions or zones of one region of the ball receiving area of the apparatus, namely, panel 18.

Limiting the discussion initially to Par 3 panel 18, the scoring values assigned to the various target zones on the panel are schematically depicted in box 114. The scoring values are used in the scorekeeping system described below. The lowest and thus most favorable score earned by a ball landing on panel 18 is assigned to hole 52. Hole 52 is termed the eagle hole, which in golf is two strokes under par. On a par 3 hole in regulation golf, an eagle is a hole-in-one. Therefore, on Par 3 panel 18, a ball which enters hole 52 is an eagle and receives a scoring value of one.

The next best score for a ball landing on panel 18 is assigned to hole 54. Hole 54 is termed the birdie hole, which in regulation golf is one under par. On a Par 3 hole in regulation golf, a birdie is two strokes. Thus, on panel 18, the birdie hole 54 is assigned a scoring value of two.

The next best shot on panel 18 is a par. A par is earned when a ball lands in the band between zone boundaries 104 and 106 on panel 18 and does not go into holes 52, 54. As described above with reference to FIG. 3, the par target zone is the region on panel 18 where balls fall or roll into ball return channel 82 without tripping sensors 92 or 94. A ball landing in the par target zone on panel 18 receives a scoring value of three, or par.

The next best score for a ball landing on panel 18 is a bogey. The target zone for a bogey score lies between zone boundaries 104 and 108 and between zone boundaries 106 and 110. In regulation golf a bogey is one stroke over par, which on Par 3 panel 18 receives a scoring value of four. The bogey target zones are the regions on panel 18 where balls fall or roll into ball return channel 82 and trip sensors 92 or 94, plus sensor 90, without tripping sensors 100 or 102.

The next best score, which in the game described is also the worst score, is assigned to the target zones furthest from longitudinal axis 24, to the left of zone boundary 108 and to the right of zone boundary 110. Those zones, lying outside boundaries 108 and 110, are termed the double bogey zones. In regulation golf, a double bogey is two strokes over par. On Par 3 panel 18, balls landing in the double bogey zones receive a scoring value of five. The double bogey zones are the regions on panel 18 where balls fall or roll into ball return channel 82 and trip either sensor 100 or sensor 102.

The scoring values assigned to the various target zones on panel 18 are depicted schematically in FIG. 4 by the lines, identified as the eagle, birdie, par, bogey and double bogey lines, drawn between selected sensors and scoring value box 114. The eagle line connects hole 52 with a scoring value of one. The birdie line connects hole 54 with the scoring value two. The par line connects sensor 90, the sensor associated with the
