with reference then to fig1 and 2 , shown is the golf swing training aid of the instant invention , generally formed as a mat 1 . critical is that the mat 1 is j - shaped and adapted to be placed on the ground . “ ground ” as used herein means any natural surface such as an actual grass golf course tee box or even a green if the device is used to putt . although the mat 1 can be placed on any artificial surface such as a driving range turf , important is that a natural divot be created by a user &# 39 ; s golf swing , as will be discussed . mat 1 can be made of a flexible or rigid material that is durable enough to withstand multiple impacts of a golf club and is preferably made of a bright color to remain easily visible to the user , but non - opaque , or slightly translucent so that some identifying ground textures remain somewhat visible . as shown , mat 1 which makes up the instant golf swing training aid , being j - shaped it includes a rear portion 23 , a short portion 24 , and a long portion 25 . short portion 24 is integral with the rear portion 23 extending therefrom defined by a linear short inside edge 11 , a short outside edge 13 parallel to the short inside edge 11 , and a short end edge 12 joining the short inside edge 11 to the short outside edge 13 . the long portion 25 is also formed integral with the rear portion 23 extending therefrom preferably parallel to the short portion 24 . long portion 25 is defined by a linear long outside edge 15 and a long inside edge 17 parallel to the long outside edge 15 . long portion 25 has a length which extends longer than the short portion 24 relative to the rear portion 23 and terminates to form a directional indicator 16 , which joins the long outside edge 15 to the long inside edge 17 . when mat 1 is placed on the ground by a golfer , the directional indicator 16 is placed in direction of the intended golf shot by pointing the directional indicator 16 to the intended target . directional indicator 16 can be an arrow , triangle , line or some other type of directional - indicating form . further describing its critical shape , mat 1 includes an arched edge 10 joining the short inside edge 11 to the long inside edge 17 . arched edge 10 is preferably arched and not linear to provide additional space behind a golf ball used with the instant mat 1 , as will be discussed with reference to the additional features of mat 1 . the arched edge 10 must provide spacing between the short portion 24 and long portion 25 that is slightly larger the size of the typical golf club head . a bottom edge 14 joins the short outside edge 13 to the long outside edge 15 to define the width of the rear portion 23 . accordingly , with all edges joined , a j - shaped mat 1 is formed having a distance between the short inside edge 11 of the short portion 24 and the long inside edge 17 of the long portion 25 defined by the arched edge 10 . a channel 26 is thereby formed between the short portion 24 and the long portion 25 adapted to have a golf ball 30 situated therein and to receive a divot resulting from impact of the golf ball 30 by a golf club . along with the shape of the mat 1 , also critical are some of the dimensions of the mat 1 . as above , the distance between the short inside edge 11 and the long inside edge 17 must be slightly wider than the width of a golf club iron . namely , the channel 26 formed between the short portion 24 and the long portion 25 has a width in the range of three to six inches , preferably between four and five inches . “ slightly ” as used herein with reference to the width of the channel means the width provides enough space for the golf club to be swung through the channel 26 if the swing is on the proper plane , but not so much space that if the swing were off - plane significantly it would not strike the mat 1 . furthermore , it is critical that the short inside edge 11 of the short portion 24 has a length which is slightly longer than the length of a typically golf swing divot . namely , the short portion 24 extends from the rear portion 23 at least six - inches , preferably in the range of eight to ten inches as measured from the middle of the arched edge 10 . the average golf professional creates a divot that starts about ½ inch in front of the golf ball and extends approximately six inches , so “ slightly ” as used with reference to the length of the short portion 24 means the short portion 24 should extend just past this typical divot length of six inches so that the divot length and other properties can be evaluated with reference to the short portion 24 . a plurality of markings is disposed throughout the surface of the mat 1 to indicate ball position and divot position . specifically , a pair of short iron indicators 19 is marked on the mat 1 . one of the short iron indicators 19 is marked on the short portion 24 and one of the short iron indicators 19 is marked in opposing relation on the long portion 25 . each short iron indicator 19 is situated a distance of approximately two inches from the arched edge , “ approximately ” meaning between one and three inches . the bottom of this range is critical in that any less there is little to no room to hit the golf ball 30 , i . e . the golf club would frequently hit rear portion 23 prior to impact . the top of the range can vary although if much larger than three inches the short portion 24 becomes excessively long . “ marked ” as used herein to refer to an indicator means any kind of surface indicia on the top of the mat made by printing , etching , or otherwise , or any type of hole or punch - through of any shape which penetrates through the mat . in the embodiment shown , as an example only , each indicator is a triangular punch - through and being through the entirety of the mat 1 , the mat 1 could be turned over and the indicators would still be visible by a left - handed golfer . the mat 1 can be used in either instance of a right - handed golfer or left - handed golfer , and if the indicators were only on the surface of the mat 1 , the same type of indicators would be printed on the opposing side . moreover , although shown in pairs it should be understood that only one of each indicator can be used , i . e . one or more . because short irons require a steeper descent and longer irons require a more shallow descent into the golf ball 30 , also provided are middle iron indicators 19 a and long iron indicators 18 . whereas to practice golf swings using short irons such as sand wedges , pitching wedges , or nine irons a golf ball is placed in alignment with the short iron indicators 19 more proximate to the arched edge 10 , the pair of middle iron indicators 19 a are used for mid - irons such as eight , seven , or six irons . in this instance the golf ball 30 would be placed near these markings . thus , the long iron indicators 18 could be used for long irons such as five , four , and three irons , in which case the golf ball 30 is placed farther from the arched edge 10 to avoid impacting rear portion 23 of mat 1 ( long irons travel through the impact zone a longer distance than short irons ). in the preferred embodiment , each middle iron indicator is situated a distance of approximately three inches from the arched edge 10 , and in turn each long iron indicator is situated a distance of approximately four inches from the arched edge . these dimensions may vary by an inch or so but it is preferred that the spacing between each indicator 19 , 19 a , 18 is approximately one inch . outermost from the arched edge 10 and thus closest to the end of short portion 24 is the divot indicator 40 . each divot indicator 40 , whether in opposing pairs or singularly , is situated a distance from the arched edge 10 in the range of five to seven inches . the exact location of the divot indicator 40 is not critical but it must reside past each of the iron indicators 19 , 19 a , 18 . the function of the divot indicator 40 is to act as a reference point for the divot which results from the swing of the golf club and the striking of the golf ball 30 . for instance in the preferred embodiment the divot indicator 40 is marked at approximately six inches from the center of arched edge 10 so that after the divot is created , under typical golf course conditions the divot should reach to or past the divot indicator 40 . thus an appropriate divot would be straight within channel 26 and extend past the divot indicator 40 but not past the end of short portion 24 . this is the critical range . in use of the mat 1 then , the golfer places a golf ball 30 centered between either the short iron indicator 19 , the mid - iron indicator 19 a , or the long iron indicator 18 . the closer the ball is in relation to the arched edge 10 , the steeper the golf club must descend into the golf ball to avoid hitting the arched cutout 10 and striking the ball short inside in a descending blow . to still function appropriately because the distances vary only by approximately one inch , it should be understood that for short irons the golf ball 30 can be placed between either indicator 19 or between indicator 19 a , for middle irons the golf ball 30 can be placed between indicator 19 a and indicator 18 , and for long irons the golf ball 30 can be placed between indicator 18 and even divot indicator 40 since for long irons the divot will either be short or near non - existent . in either instance an appropriate approximation of divot length is obtained because the divot will still extend between divot indicator 40 and the end of short portion 24 . once the golf ball 30 is struck , the golf club will create a divot starting slightly after where the ball was placed . when the mat 1 is used on a natural grass , the golfer can measure the divot length created with reference to the short portion 24 and long portion 25 , and can also examine the divot direction with reference to both . as above , the average golf professional creates a divot that starts about ½ inch in front of the golf ball and extends approximately six ( 6 ) inches . the swing bottoms out approximately four ( 4 ) inches in front of the ball and the divot is deepest at this location . if the golfer looses this angle , or shaft lean , the golf club will strike the j shaped golf training mat 1 . the golfer will also be forced to swing the golf club on a straight plane through the impact zone of the golf ball and release the energy stored by lagging the golf club head into the hack of the ball creating a divot after the golf ball 30 . the golfer is also forced into a swing path that proceeds slight inside ( before impact ), to square ( at impact ), to slight inside ( after impact ) by forcing the club head path inside the j - shaped channel . if the golfer does not maintain this swing path , the golfer will strike the j - shaped golf training mat . this will improve the golfer &# 39 ; s chance of scoring low by achieving proper impact dynamics . additional features include the mat &# 39 ; s ability to be used by right - handed golfers or left - handed golfers by turning the mat 1 over , as referenced above . furthermore , the mat 1 comprises one or more holes 21 defined throughout the mat 1 configured to receive and hold tees which can be used to hold down and maintain the mat on the natural surface . while the foregoing written description of the invention enables one of ordinary skill to make and use what is considered presently to be the best mode thereof , those of ordinary skill will understand and appreciate the existence of variations , combinations , and equivalents of the specific embodiment , method , and examples herein . the invention should therefore not be limited by the above described embodiment , method , and examples , but by all embodiments and methods within the scope and spirit of the invention as claimed .
a golf swing training aid to assist golfers with multiple skills required in the game of golf and assist the golfer in creating a repeatable impact position with all golf shots . a short portion and a parallel long portion both connect to a rear portion and define a channel . the short portion is shorter than the long portion to form a j - shaped mat . a golf ball is placed between the two portions at designated markers depending on the type of golf iron used , and the size of the divot resulting from impact can be estimated using the one or more other markers along the short and long portion to help evaluate the swing and direction of the golf club as a result of the size and direction of the divot .
