Abstract
A head cover for covering a head and an adjacent shaft portion of a golf club including an outer sleeve and an inner liner each of which has a generally tubular configuration with a closed upper end and open bottom end. The open bottom ends of the outer sleeve and the inner liner are sewn together with an inverted V-shaped slot extending from the open bottom ends toward the closed upper ends thereof. The longitudinal dimension of the inner liner is less than the longitudinal dimension of the outer sleeve to provide a gap between the closed upper ends of the inner liner and the outer sleeve. When installed on a golf club, the head of the golf club pushes the closed upper end of the inner liner into engagement with the closed upper end of the outer sleeve closing the gap and partially closing the open bottom end of the inner liner. This closes the inverted V-shaped slots in the outer sleeve and the inner liner. The golf club head cover may be provided with a detachable identification tag.
Description




BACKGROUND OF THE INVENTION




This invention relates in general to golf equipment and, more particularly, to an improved golf club head cover and a method of making the same.




It is a common practice to use head covers on golf clubs, particularly on those clubs referred to as “woods”, to protect them from damage when not in use. These head covers are usually made of flexible material such as fabric and are of a generally tubular configuration with one end being open and the other end being closed. There are two basic types of head covers currently in use with an older design being intended for use on woods having steel shafts and a newer design specially designed for use on woods having graphite shafts. The head covers normally used on steel shafted woods are relatively short since steel shafts do not require any special protection. An example of this type of prior art head cover is disclosed in U.S. Pat. No. 4,667,716 to John A. Solheim et al.




Unlike their steel shafted counterparts, woods having graphite shafts need special protection for the graphite shafts when they are carried in golf bags. When golf clubs are placed in a golf bag, the golf club heads extend above the top of the golf bag and the golf club shafts are surrounded by and divided into groups by a throat structure including an outer rim and divider bars. U.S. Pat. No. 4,596,328 to John A. Solheim discloses a typical throat structure. Any movement of the golf clubs in the golf bag, such as occurs when the golf bag is being carried, will cause the golf club shafts to rub against the outer rim and the divider bars of the throat structure. In the absence of some form of protection, this rubbing will result in abrasive damage to graphite shafts which mars their appearance.




To alleviate the abrasive damage problem to graphite shafts, the newer design of prior head covers, which are sometimes referred to simply as “graphite head covers”, are considerably longer than the head covers used on steel shafted clubs. The additional length of the graphite head covers are intended to cover portions of the graphite shafts which extend down through the throat structure of the golf bag and thus shield those shaft portions from abrasive damage. These prior graphite head covers include a pouch-shaped upper portion for containing a golf club head and a tail portion depending from the upper portion. The pouch shaped upper portion is usually made of flexible material, such as synthetic leather, and the tail portion is of knitted construction which expands and contracts when a golf club head is passed through it as the head cover is installed on or removed from a golf club. Since the tail portion is knitted, it will only expand to a limited extent and although it is relatively slim in comparison to the pouch shaped upper portion, it must be large enough to allow passage of the golf club head. As these prior graphite head covers are used, repeated stretching of the knitted tail portion will cause it to lose its elasticity and when this occurs, the tail portion will permanently increase in diameter.




A golfer frequently cares three or four wood type dubs in a golf bag, and the section of the throat structure in which these clubs are carried is rather crowded when the prior graphite head covers are used. Such crowding often causes the tail portions of the graphite head covers to catch on the outer rim or the divider bars of the throat structure when the clubs are inserted into the golf bag. This problem is aggravated as the tail portions become stretched with use. When these tail portions catch on the throat structure as the clubs are inserted into the golf bag, the tail portions ride up on the shafts and remain bunched up above the throat structure. This, of course, defeats the primary purpose of the tail portions of the graphite head covers.




SUMMARY OF THE INVENTION




A head cover according to the present invention is formed with an outer sleeve and an inner liner both of which are configured to provide the head cover with an elongated receptacle having an upper pocket for containing a head of a golf club and a lower pocket for containing a portion of a shaft adjacent the golf club head. The golf club head passes through the lower pocket when the head cover is installed on or removed from the golf club. The outer sleeve and the inner liner are of unique configuration and are sewn together in a special manner so that the lower pocket is normally open to allow passage of the golf club head but closes about the adjacent shaft portion when the golf club head enters the upper pocket.




In the preferred embodiment of the head cover, both the outer sleeve and the inner liner are of generally tubular configuration with a closed upper end and an open bottom end. Furthermore, the outer sleeve and the inner liner each have an inverted V-shaped slot extending from the open bottom end toward the closed upper end. The outer sleeve has a first longitudinal dimension, and the inner liner has a second longitudinal dimension which is less than the first longitudinal dimension so that a gap is provided between the closed upper ends of the outer sleeve and the inner liner. When the head cover is installed on a golf club head, the inner liner closed upper end is pushed toward the outer sleeve closed upper end to close the gap and partially close the open bottom end of the inner liner. This closes the inverted V-shaped slots in the inner liner and the outer sleeve which closes the lower pocket.

DESCRIPTION OF THE PREFERRED EMBODIMENT




Referring to the drawings,

FIGS. 1

,


2


,


3




a


and


3




b


show a head cover according to the present invention which is indicated generally by the reference numeral


10


. The head cover


10


includes an outer sleeve


12


which is elongated and of generally tubular configuration having a closed upper end


14


. An inner liner


16


which is disposed within the outer sleeve


12


is also elongated and of generally tubular configuration with a closed upper end


18


. The outer sleeve


12


and the inner liner


16


have respective open bottom ends


13


and


17


as best seen in

FIG. 3



a


. The outer sleeve


12


and the inner liner


16


cooperatively provide the head cover


10


with an elongated receptacle


20


which has an upper pocket


22


at one end


23


and a lower pocket


24


at the other end


26


. The outer sleeve


12


and the inner liner


16


each have an inverted V-shaped slot at


28


extending from their respective open bottom ends


13


,


17


toward their respective closed upper ends


14


,


18


.




As described later, the outer sleeve


12


and the inner liner


16


are sewn together in a special manner, and the inner liner


16


has a longitudinal dimension that is less than a longitudinal dimension of the outer sleeve


12


to provide a gap


30


between the closed upper end


14


of the outer sleeve


12


and the closed upper end


18


of the inner liner


16


. In

FIG. 1

, the head cover


10


is shown in a relaxed condition when not in use on a golf club. When the head cover


10


is in this relaxed condition, edges


32


and


34


which define the inverted V-shaped slots at


28


in the outer sleeve


12


and the inner liner


16


diverge downwardly from an apex


36


toward the end


26


of the receptacle


20


.




When the head cover


10


is installed for use on a golf club


38


having a head


40


and a shaft


42


as shown in

FIG. 2

, the head cover


10


is pulled downwardly over the head


40


until the head


40


is in the upper pocket


22


and engages the closed upper end


18


of the inner liner


16


. This pushes the closed upper end


18


of the inner liner


16


against the closed upper end


14


of the outer sleeve


12


and thereby closes the gap


30


. Closing the gap


30


causes the inner liner


16


to pull the edges


32


and


34


toward each other partial closing the open bottom end


17


of the inner liner


16


. This closes the V-shaped slots at


28


which closes the lower pocket


24


about a portion


42




a


of the shaft


42


adjacent the head


40


. When the lower pocket


24


is closed, the lower end


26


of the receptacle


20


will be substantially reduced in size so that it will easily fit into a golf bag (not shown). To insure that the lower pocket


24


remains closed, the head cover


10


may be provided with cooperating elements


44


and


46


of a hook and loop fastener which are positioned proximate the edges


32


and


34


.




Referring now to

FIG. 4

, steps of a method of making the head cover


10


are shown. The first step includes cutting, with a suitable die (not shown), two sheets of flexible material


12




a


,


16




a


such as fabric, with the lower sheet


12




a


being used to form the outer sleeve


12


, with the lower sheet


12




a


being laid flat with its outer surface facing upwardly, and the upper sheet


16




a


which will form the inner liner


16


, being similarly laid flat in a superimposed position on the lower sheet


12




a


. It will be seen that the upper sheet


16




a


is longitudinally shorter than the lower sheet


12




a


as shown at


48


to provide the gap


30


between the closed upper ends of the inner liner


16


and the outer sleeve


12


as already described. The lower and upper sheets


12




a


,


16




a


will be collectively referred to as the “material”. The material has a longitudinal axis


50


which bisects the material and divides it into symmetrical halves. As seen in

FIG. 4

, edge regions


52


,


54


of the upper sheet


16




a


are spaced inwardly from the edge regions


52


,


54


of the lower sheet


12




a


along at least part of their length. This results in the inner liner


16


having a smaller circumference than the outer sleeve


12


in that part of its length which assists in closing the V-shaped slots at


28


as already described. Each of the edge regions


52


and


54


of the sheets


12




a


,


16




a


are provided with a lower land segment


56


proximate what may be described as the tail end edge


57


of the material, and an upper land segment


58


proximate the opposite, or upper, end


59


thereof. An inwardly curved edge segment


60


is formed in each of the edge regions


52


and


54


intermediate the upper and lower land segments


56


and


58


respectively thereof.




The tail end edge


57


of the material is formed with relatively short land areas


62


at its opposite ends and intermediate edge segments


64


which extend upwardly and inwardly from the inner ends of the land areas


62


to form the edges


32


and


34


. The upper end edge


59


of the material include protruding central flaps


66


having tabs


67


and land portions


68


on extending ends and preferably formed with outwardly curved side edge portions


70


and


72


. The innermost ends of the curved side edge portions


70


and


72


form junction points


74


and


76


with the inner ends of end edge segments


78


and


80


that extend from their respective junctions


74


and


76


to the uppermost ends of the edge regions


52


and


54


. The end edge segments


78


and


80


are curved to match the side edge portions


70


and


72


of the protruding central flaps


66


.




When the material is cut into the above described configuration and the sheet


16




a


forming inner liner


16


is in the superimposed position atop the sheet


12




a


forming the outer sleeve


12


, the material is then sewn as at


82


along the length of the tail end edge


57


of the material and this includes sewing of the intermediate edge segments


64


which form the edges


32


and


34


. This step may include the insertion of the element


44


of the hook and loop fastener between the two sheets


12




a


,


16




a


so that it will be stitched in place during sewing of the seam


82


.




The lower sheet


12




a


of the material, that forms the outer sleeve


12


, is then folded about the longitudinal axis


50


in the manner indicated by the arrows


84


in

FIG. 4

until the edge regions


52


and


54


of the sheet


12




a


forming the outer sleeve


12


are in touching aligned relationship. Prior to folding the lower sheet


12




a


about the longitudinal axis


50


, the upper sheet


16




a


is moved downwardly in

FIG. 4

so that it is out of the way. The upper sheet


16




a


of material, that forms the inner liner


16


, is folded until its edge regions


52


and


54


are in touching aligned relationship. When the sheets


12




a


,


16




a


forming the outer sleeve


12


and inner liner


16


are folded in this manner, they will be positioned relative to each other as seen in FIG.


5


. The sheet


12




a


forming the outer sleeve


12


is then sewn at


86


to form a sewn seam at the aligned edge regions


52


and


54


thereof and the sheet


16




a


forming the inner liner


16


is subsequently sewn as at


88


to sew the aligned edge regions


52


,


54


together.




The protruding flap


66


of the sheet


12




a


forming the outer sleeve


12


is then folded downwardly as indicated by the arrow


90


in

FIG. 5

to bring the land portion


68


and the curved side edge portions


70


and


72


of the flap


66


into touching alignment with the curved end edge segments


78


and


80


formed at the upper end edge


59


thereof and those aligned edges are then sewn as at


92


to close the upper end


14


of the outer sleeve


12


. The sheet


16




a


is then folded downwardly in

FIG. 5

in the direction of arrow


91


, and the tabs


67


are stitched to each other. When sewn as described, fabrication of the outer sleeve


12


will have been completed, however it will be in an inside-out position. It is sewn in this manner so that the seams formed along the longitudinal edges of the outer sleeve


12


and at the closed upper end


14


thereof will be inside the outer sleeve


12


, and thus hidden from view, when the outer sleeve


12


is turned right-side out.




Prior to sewing the flap


66


of the outer sleeve


12


closed and turning it into the right-side-out position, a fabric strip


67


having a special connector


96


positioned thereon, is folded back upon itself to form a loop and is placed in the open upper end of the outer sleeve


12


as indicated in FIG.


5


. With the fabric strip


67


and connector


96


positioned as shown, when the outer sleeve


12


is closed by stitching of the sewn seam


92


, the aligned ends of the fabric strip


67


will be simultaneously stitched into that seam so as to become captively affixed to the closed upper end


14


of the outer sleeve


12


.




Turning the outer sleeve


12


right-side-out is the next step and this is accomplished by pushing the closed upper end


14


of the outer sleeve


12


into and through the interior of the outer sleeve


12


, through the slot


28


, and into the interior of the inner liner


16


to the position shown in FIG.


6


. It will be understood that the position shown in

FIG. 6

is a transitional position and movement of the outer sleeve


12


through the inner liner


16


is continued until the outer sleeve


12


has passed completely through the inner liner


16


. The flap


66


of the inner sleeve


16


is then folded into the closed position in the manner previously described with reference to the outer sleeve


12


and sewn to form the seam


97


. When the upper end


18


of the inner liner


16


is closed, fabrication of the head cover


10


is completed by pushing the inner liner


16


through the slot


28


into the interior of the outer sleeve


12


and attaching the loop portion


46


to the outer sleeve


12


as shown in

FIGS. 1 and 2

.




Referring again to

FIG. 4

, the lower and upper land segments


56


and


58


respectively and the inwardly curved segments


60


provide the edge regions


52


and


54


of the material with a special configuration. When those edge regions


52


,


54


are sewn together in the manner hereinbefore described, the lower land segments


56


will shape the lower end


26


of the receptacle


20


(

FIG. 3

) of the head cover


10


so that it acts as a ramp which leads into a constricted area


98


between the upper and lower pockets


22


,


24


formed by the inwardly curved edge segments


60


, and the upper land segments


58


form the upper pocket


20


at the end


23


of the receptacle


20


. When the head cover


10


is installed on a golf club


38


, this ramp in the receptacle


20


will provide a smooth movement of the head cover


10


down over the golf club head


40


and into the constricted area


98


of the receptacle


20


. Upon entering the constricted area


98


, the person installing the head cover


10


will need to exert slightly more pulling force and the velocity of the golf club head


40


will increase upon leaving the constricted area


98


and entering the upper pocket


22


. By increasing the velocity of the club head


40


as it enters the upper pocket


22


, an appreciable amount of force will be exerted on the inner liner


16


which will push it upwardly to close the gap


30


between the inner liner


16


and the outer sleeve


12


and thereby close the lower pocket


24


around the shaft portion


42




a


. When the head cover


10


is removed from the golf club


38


, the inner liner


16


is prevented from being pulled out of the outer sleeve


12


since the tabs


67


are connected to each other.




Referring now to

FIGS. 7 and 8

wherein the structural details of a detachable identification tag


100


are shown. The detachable tag


100


includes a substantially planar body of any desired shape which is molded or otherwise formed, such as from a suitable synthetic resin, and has golf club identification indicia


102


on at least one side thereof. The tag


100


is formed to define an especially configured slot


104


for demountably receiving the hereinbefore mentioned special connector


96


. The slot


104


is of elongated configuration with webs


106


and


108


extending toward each other from opposite ends of the slot and the webs are of reduced thickness in comparison to the thickness of the body of the tag


100


so that the webs have the capability of being resiliently deflectable for reasons which will become apparent as this description progresses. The inwardly disposed ends of the webs


106


and


108


define the opposite ends of a generally rectangular central opening


110


formed through the tag body


100


. The upper and lower longitudinal sides of the slot


104


are notched as at


112


and


114


to provide clearance for the fabric strip


94


during mounting of the tag


100


on the connector


96


. In that the webs


106


and


108


are of reduced thickness, recessed cavities


116


and


118


are defined on opposite sides of each of the webs.




The connector


96


, which may also be molded or otherwise formed of a suitable synthetic resin, has a body of generally T-shaped configuration including an eyelet


120


and an integral cross bar


122


. The cross bar is tangentially disposed relative to the eyelet


120


to provide oppositely extending arms


124


and


126


. The eyelet


120


defines an elongated opening


128


through which the fabric strip


94


is threadingly passed. The eyelet


120


is shown as being of generally oval configuration having a width dimension “A” which lies along a major axis which is parallel to the cross bar


122


. It will be understood that the eyelet


120


may be of various other configurations such as circular (not shown) in which case dimension “A” would be the diameter of the circle. Therefore, it will be understood that dimension “A” will be the width of the eyelet


120


taken along a line parallel to the cross bar


122


. The connector


96


has a neck


130


at the tangential junction of the eyelet


120


and the crossbar


122


, and the neck has a width dimension which is less than the width dimension “A” of the eyelet to provide recesses


132


and


134


on opposite sides of the neck.




To demountably attach the identification tag


100


to the connector


96


, the connector is turned sideways and pushed through the central opening


110


of the slot


104


of the tag as indicated in dashed lines in FIG.


8


. After being pushed through the central opening


110


of the slot


104


in this manner, the connector is then turned through about


90


degrees of rotation to bring the cross bar


122


into parallel relationship with the slot


104


to locate the eyelet


120


proximate the central opening


110


of the slot. The width dimension “A” of the eyelet


120


is greater than the longitudinal dimension of the central opening


110


of the slot and the width dimension of the neck


130


is approximately equal thereto. Therefore after the connector


96


has been rotated as described above it will need to be forcefully pushed into the installed position. The larger width dimension “A” of the eyelet


120


will deflect the webs


106


and


108


as it passes through the temporarily enlarged central opening


110


of the slot


104


, and the deflected webs will resiliently snap into the recesses


132


and


134


on opposite sides of the neck


130


of the connector


96


.




By being connectable to the head cover


10


in the above described manner, the particular identification tag


100


to be installed may be selected from a plurality of such tags having various golf club indicia thereon and, the selection and installation may be accomplished at the time of purchase. Thus simplilying both the manufacturing and supplying of the product. If for any reason it should become necessary or desirable to replace an installed tag


100


with a different one, it can be easily accomplished by simply reversing the above described installation procedure.
