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.
