Description

    CROSS-REFERENCE TO RELATED APPLICATIONS
  • This application is a continuation-in-part patent application of U.S. patent application Ser. No. 14/455,254 filed Aug. 8, 2014, the contents of which are expressly incorporated herein by reference.
  • STATEMENT RE: FEDERALLY SPONSORED RESEARCH/DEVELOPMENT
  • Not Applicable
  • BACKGROUND
  • 1. Technical Field
  • The present disclosure pertains generally to golf clubs and, more particularly, to a tape based weighting system which, when applied to a golf club head, displays indicia on a rear surface of the golf club head.
  • 2. Description of the Related Art
  • Weighted tapes, for example, manufactured of lead and/or other metals or alloys, are known in the field of sporting goods, particularly in connection with golf clubs. Traditionally, weighted tapes have been used on golf clubs for two main purposes: 1) to alter the swing weight of the club, and 2) to move the center of gravity. This use of the weighted tape may help fine-tune the swing weight and/or center of gravity of the club to alter such characteristics relative to what is available on standard equipment in order to customize the club for the golfer's particular use. Such customization may translate into hitting better shots, which in turn may help boost the golfer's morale and performance. Thus, the use of weighted tape is common and wide spread.
  • Previous uses of weighted tape in the golf industry, however, have been inefficient. Golfers use their best judgment to tear off a piece of weighted tape with unknown weight and apply it, often indiscriminately, to any place on the golf club. More often than not, using weighted tape has meant that one or more weighted tape pieces usually end up being applied on top of the branding indicia on the golf club. This leads to obscuring the brand and the message on the golf club.
  • Thus, the previous usage of weighted tape was inefficient in increasing the swing weight of the golf club and also in moving the center of gravity. It also obscured the brand name and message of the club.
  • In view of the aforementioned deficiencies in the art, there is a need for a tape based golf club head weighting system which, when applied to a golf club head, provides a desirable appearance of indicia on the rear face thereof, while also providing desired weight modification characteristics.
  • BRIEF SUMMARY
  • In one embodiment, a golf club head may have first branding indicia, which may, for example be a logo, picture, pattern, graphics, or text of any kind. This golf club head may also comprise a weight having second branding indicia thereon. The second branding indicia may be substantially similar to the first branding indicia. The golf club may also have a predefined region encompassing, at least in part, the first branding indicia. This predefined region may be sized, shaped and located depending on the location of the center of gravity. The predefined region may include at least a portion of the first branding indicia. The weight may have a size and shape substantially similar to the first predefined region.
  • Moreover, the weight may, in some cases, only be applied to the exterior surface of the golf club. The weight may be applied as a singular weight or a combination of weights, each weight being substantially similar to the other in size and shape, and all of the weights being substantially similar in size and shape to the predefined region on the golf club.
  • In another embodiment, a golf club head may include a rear surface with first branding indicia thereon. The first branding indicia may be inside the predefined region such that the predefined region defines the location where the weight is intended to be applied to the golf club head.
  • In another embodiment, a golf club head may include a rear surface with the first branding indicia thereon. The weight with the second branding indicia may be placed on the rear surface of the golf club head. The weight may completely cover the first branding indicia. The weight may be substantially similar in size and shape to the predefined region on the golf club.
  • In another embodiment, a golf club head may include a rear surface with the first branding indicia thereon. The weight with the second branding indicia can be displaced from the predefined region exposing some part of the first branding indicia in the predefined region.
  • In another embodiment, a weighted tape may include second branding indicia thereon, the weighted tape comprising, for example, round, rectangular, or oval-shaped weighted tape adhesively backed with peel off portions.
  • In another embodiment, a weighted tape may include second branding indicia thereon and comprise a tape portion that can be torn off of a roll or strip of the weighted tape at predetermined lengths marked, for example, by perforated lines or score lines.
  • In another embodiment, a golf club may include one or more predefined regions on the rear surface of the golf club. The predefined regions may be of any shape and size, and may be sized and shaped to accept a weighted tape of substantially the same size and shape, and may be shaped to accept the weighted tape in only one orientation.
  • According to another embodiment, there is provided a golf club head accessory comprising a weighted tape attachable and conformable to a golf club head. The weighted tape includes an adhesive layer and a weighted layer having an inner surface proximate the adhesive layer and an exterior surface opposite the interior surface, with the exterior surface having indicia thereon that forms a repeating pattern.
  • The repeating pattern may be embossed into the weighted tape. The repeating pattern may comprise a plurality of raised surfaces or a plurality of recessed surfaces.
  • The weighted tape may be sized and configured to correspond to a predetermined swing weight adjustment weight following application of the weighted tape thereto.
  • The weighted layer may comprise at least one of lead, tin, bismuth, steel, ceramic, stone, pewter, tungsten, and tungsten-nickel alloy. The weighted layer may comprise an appliqué having the adhesive layer disposed thereon. The weighted layer may comprise a roll forged metal layer. The weighted layer may comprise a forged layer.
  • The indicia may define a quadrangular type pattern.
  • The weight tape may comprise a density no less than 4 g/cc. The weight tape may comprise a density no less than 7 g/cc. The weight tape may comprise a density no less than 10 g/cc.
  • There is also provided a method of manufacturing a weighted tape for association with a golf club head. The method includes forming a weighted layer having a density greater than 7 g/cc and a recurrent embossed pattern by roll forging a stock material using a patterned die, and applying an adhesive material to the weighted layer.
  • The method may further comprise the step of configuring the weighted tape to correspond to a predetermined swing weight adjustment weight.
  • According to yet another embodiment, there is provided a method of manufacturing a weighted tape for association with a golf club head. The method includes forming a weighted layer having a recurrent embossed pattern by roll forging a stock material using a patterned die, the recurrent pattern comprising a quadrangular type pattern. The method also includes applying an adhesive material to the weighted layer.
  • The various exemplary aspects described above may be implemented individually or in various combinations. These and other features and advantages of the golf club head and related accessory according to the disclosure in its various aspects and demonstrated by one or more of the various examples will become apparent after consideration of the ensuing description, the accompanying drawings, and the appended claims.

  • DETAILED DESCRIPTION
  • Referring now to the drawings wherein the showing are for purposes of illustrating preferred embodiments of the present disclosure, and not for purposes of limiting the same, FIG. 1 depicts a club weighting system of the prior art, consisting of a golf club head 100 defining a rear surface 105 having branding indicia 110 applied to a prescribed region or area thereof. As illustrated, the prior art club weighting system also consists of a segment of plain lead tape 115 applied over at least a portion of the first branding indicia 110.
  • In greater detail, in the prior art, the lead tape 115 is applied casually over the branding indicia 110, so that the branding indicia 110 is at least partially obscured. Also, the lead tape 115 has a plain exterior surface 120 with no branding indicia thereon. This arrangement leads to the branding indicia 110 being fully or partially hidden from the viewer due to the overlapping plain lead tape 115. As illustrated, the prior art lead tape 115 is often applied with uneven borders and/or in uncertain weight, and/or in haphazard placement, leading to uncertain repeatability from club to club or when it becomes necessary to replace the lead tape 115.
  • Referring to FIG. 2, there is shown an exemplary golf club head 200 suitable for use in conjunction with the weighting system of the present disclosure. The golf club head 200 mirrors many of the structural features of the golf club head 100 described above, and defines a rear surface 205. Disposed at a prescribed region or area of the rear surface 205 is a predefined region 210. In many gold club head designs, the predefined region 210 is recessed or elevated relative to the remainder of the rear surface 205, or otherwise differentiated therefrom by some form of a visual line of demarcation. Applied to the club head 200 within the predefined region 210 is first branding indicia 215. The first branding indicia 215 may be formed or placed on or in the rear surface 205 of the golf club head 200 using any known method and, for example, may be etched, embossed, punched, stamped, painted, or lacquered, on the golf club head 200. In FIG. 2, the predefined region 210, and hence the first branding indicia 215, is spaced from the sole 220 of the gold club head 200 by a prescribed distance.
  • In the golf club head 200 shown in FIG. 2, the first branding indicia 215 may comprise a logo, brand name, or any other form of indicia. In a preferred aspect, the branding indicia 215 may comprise a brand associated with the manufacturer of the golf club head 200, for example, “Cleveland.” The predefined region 210 is which the first branding indicia 215 preferably reside may be of any shape and design. As illustrated in FIG. 2, the predefined region 210 may comprise a polygon, such as a trapezoidal region. Those of ordinary skill in the art will recognize that the predefined region 210 may also be provided in sizes and/or shapes varying from that shown in FIG. 2 without departing from the spirit and scope of the present disclosure. Along these lines, the predefined region 210 may be defined at least in part by indicia selected from the group comprising lines, line segments, arcs, arc segments, dashes, dots, and corner segments. Additionally or alternatively, the predefined region 210 may be defined at least in part by one or more of a partially raised surface, a fully raised surface, a partially sunken or recessed surface, a fully sunken or recessed surface, a stepped surface, a textured surface, and a partially raised/partially sunken or recessed surface.
  • Referring to FIG. 3, in accordance with one embodiment of the present disclosure, a pre-cut weighted tape segment 310 is applied to the rear surface 205 of the golf club head 200 to facilitate the implementation of the weighting system. The weighted tape segment 310 may be sized and shaped to substantially conform to the size and shape of the predefined region 210 illustrated in FIG. 2. The weighted tape segment 310 may comprise tape that has been scored, perforated, punched, or otherwise pre-sized. As depicted in FIG. 3, the predefined region 210 and the weighted tape segment 310 are substantially similar in size and shape. The weighted tape segment 310 may have second branding indicia 315 on an exterior surface thereof which is substantially similar to the first branding indicia 215 illustrated in FIG. 2.
  • With greater particularity, the weighted tape segment 310 may substantially or completely cover the first branding indicia 210 illustrated in FIG. 2, and may substantially or completely fit in, fill or otherwise cover the predefined region 210 illustrated in FIG. 2. In FIG. 3, the weighted tape segment 310 is sized and shaped to completely cover the first branding indicia 210 and to completely cover the predefined region 210 as well. As indicated above, the predefined region 210 may be defined at least in part by indicia selected from the group comprising lines, line segments, arcs, arc segments, dashes, dots, and corner segments, which may be formed on the rear surface 205 using known methods including etching, stamping, molding, painting, casting, milling, and the like.
  • Referring to FIG. 4, in accordance with another embodiment of the present disclosure, the pre-cut weighted tape segment 310 is applied to a golf club head 200 so as to be disposed slightly offset from the predefined region 210 such that the weighted tape segment 310 substantially, but not fully, covers the first branding indicia 215 in the predefined region 210. In this regard, the weighted tape segment 310, when misplaced or offset in the predefined region 210 on the rear surface 205 of the golf club head 200 may leave some part of the first branding indicia 215 on the predefined region 210 exposed. Thus, even though the weighted tape segment 310 is misplaced or offset, it still has the second branding indicia 315 which may be substantially similar to the first branding indicia 215.
  • Those of ordinary skill in the art will recognize that in the gold club head 200, the distance separating the predefined region 210, and hence the first branding indicia 215, from the sole 220 as shown in FIGS. 2 and 4 is exemplary only. Along these lines, the techniques described above for applying the weighted tape segment 310 to the golf club head 200 will be, in most instances, unaffected by any increase or decrease in the distance separating the predefined region 210 and/or first branding indicia 215 from the sole 220 from that shown in FIGS. 2 and 4.
  • Another embodiment of the disclosure is illustrated in FIG. 5. In this embodiment, a golf head 200A is depicted that is similar to the gold club head 200, but includes several predefined regions formed within the rear surface 205A thereof. In greater detail, the gold club head 200A, as illustrated in FIG. 5, is formed to include three predefined regions 210A, 210B, 210C on the rear surface 205A. Such predefined regions 210A, 210B, 210C may, when a weighted tape segment is applied to the golf club head 200A, define and/or represent different center of gravity adjustments (three in this example) to the gold club head 200A. As illustrated, the predefined regions 210A, 210B, 210C may each be sized and shaped substantially the same and/or to substantially “capture” the branding indicia 215A of the golf club head 200A therein. It is contemplated that one or more pre-cut weighted tape segment, like the weighted tape segment 310, may be applied to the golf club head 200A to cover the branding indicia 215A and/or reside on or within one or more of the predefined regions 210A, 210B, 210C. In this regard, regardless of which of the predefined regions 210A, 210B, 210C a weighted tape segment of substantially the same size and shape is positioned, the branding indicia 215A may be substantially covered, and/or be effectively replaced by, for example, the second branding indicia 315 on the pre-cut weighted tape segment 310.
  • Another embodiment of the disclosure is illustrated in FIG. 6. In this embodiment, several weighted tape segments of different size, shape and dimension are applied to the rear surface 205 of the golf club head 200. In the exemplary implementation of multiple tape segment usage as depicted in FIG. 6, three weighted tape segments 310A, 310B, 310C of different size and shape are applied to the rear surface 205. As is apparent from FIG. 6, such weighted tape segments 310A, 310B, 310C may contain all or a portion of the second branding indicia 315 shown in relation to the above described weighted tape segment 310. In greater detail and by way of example, the weighted tape segment 310A includes second branding indicia 315A which is complete and mirrors the second branding indicia 315. On the other hand, the weighted tape segments 310B, 310C include only portions of the complete second branding indicia 315, such as the partial second branding indicia 315B included on the weighted tape segment 310B.
  • As illustrated in FIG. 6, the weighted tape segments 310A, 310B, 310C may be applied at various positions on the rear surface 205 of the golf club head 200. As depicted, each of the weighted tape segments 310A, 310B, 310C may cover some portion of the predefined region 210 (not shown in FIG. 6) on the golf club head 200. In this aspect, the weighted tape segments 310B, 310C positioned beneath the uppermost weighted tape segment 310A may have all or a part of the second branding indicia thereof, such as the partial second branding indicia 315B, obscured by the top weighted tape segment 310A. Along these lines, the second branding indicia (not shown) included on the lowermost weighted tape segment 310C may be completely or partially obscured by the weighted tape segments 310B and/or 310A. As illustrated in FIG. 6, the second branding indicia 315A on the top most weighted tape segment 310A is preferably fully visible, to give a substantially certain indication of the brand to the viewer.
  • Referring now to FIG. 7, it is contemplated that any segment of weighted tape used in the weighting system of the present disclosure may be provided in the form of a weighted tape segment 410 which has second branding indicia 415 thereon. In a preferred implementation, several weighted tape segments 410 are positioned in series and may be selectively peeled from a common base layer 500. In an alternative implementation, the weighted tape segments 410 may be integral portions of the base layer 500 separable from the remainder thereof by the fracture of perforations or frangible score lines. In this alternative implementation, it is contemplated that the side or face of the base layer opposite that including any second branding indicia 415 may have a layer of adhesive applied thereto which is exposed upon the removal of a backing strip (not shown) which covers the same. In FIG. 7, the weighted tape segments 410 are each shown as having an oval shape. However, those of ordinary skill in the art will recognize that other sizes and shapes are contemplated to be within the spirit and scope of the present disclosure, including those of the above-described weighted tape segments 310, 310A, 310B, 310C. Also, the second branding indicia 415 may be embossed on the corresponding weighted tape segments 410, or printed on a top layer thereof, or printed on an envelope enclosing the same.
  • Referring now to FIG. 8, it is also contemplated that any segment of weighted tape used in the weighting system of the present disclosure may extracted from within an elongate strip 600 which contains a number of pre-cut weighted tape segments 510 which are each of a pre-defined size, shape and weight. The individual weighted tape segments 610 may each include second branding indicia 515 thereon, are separated from each other within the strip 600 by perforations or frangible score lines 605. These score lines 605, preferably provided at consistent, predetermined intervals, create a consistent look, and allow for the tearing off of the weighted tape segment 510 one at a time, as needed. The second branding indicia 515 may be embossed on strip 600, or printed on a clear or transparent top layer. Each weighted tape segment 510 may comprise a known mass enabling known adjustments to the swing weight and/or center of gravity of the golf club head, such as the gold club head 200, 200A, to which it is applied. Along these lines, it is also contemplated that each of the weighted tape segments 510 may comprise at least one appliqué which itself comprises an adhesive layer applied to corresponding weighted portion.
  • Referring to FIG. 9, there is shown a golf club head 200B which is similar to the golf club head 200 described above, and defines a rear surface 205B. In the golf club head 200B, the rear surface 205B is preferably formed to include one or more pre-defined recommended weighted tape placement positions. In the exemplary embodiment shown in FIG. 9, one of these positions is sized and shaped to be complimentary to, and therefore accommodate, a weighted tape segment 410. A remaining one of the placement positions is sized and shaped to be complimentary to, and therefore accommodate, a weighted tape segment 510B similar to by comprising a slightly elongated version of the weighted tape segment 510. The size and shape of the placement positions, and weighted tape segments 410, 510B applied thereto, as shown in FIG. 9 is exemplary only, in that placement positions of varying size, shape and/or location may be laser etched or otherwise formed in the rear surface 205B. Indeed, these locations could potentially be laser etched into the rear surface based on user's swing as determined, for example, by a fitting application or club fitting procedure. As will be recognized, any weighted tape segments used in conjunction with the golf club head 200B will be provides in sizes/shapes which correspond to those of any placement position(s) formed in the rear surface 205B.
  • The present disclosure serves to address the problem of the prior art (FIG. 1) by showcasing a similar branding indicia (e.g., second branding indicia 315, 315A, 415, 515) as is originally on the golf club 200 in the form of the first branding indicia 215. As indicated above, the first branding indicia 215 and the second branding indicia 315, 315A, 415, 515 may be substantially similar in size, or shape, message, or appearance, but in other aspects may comprise different branding indicia and/or different size, shape, message, or appearance.
  • The pre-cut weighted tape segment 310, 310A, 310B, 310C, 410, 510 may comprise any material, including but not limited to lead, tin, bismuth, steel, ceramic, stone, pewter, tungsten-nickel alloy and mixtures or alloys thereof. In addition, as also indicated above, each pre-cut weighted tape segment 310, 310A, 310B, 310C, 410, 510 may comprise a known mass enabling known adjustments to the swing weight and/or center of gravity of the golf club head to which it is applied.
  • Referring now to FIGS. 10-12, there is depicted another embodiment of weighted tape 710 having indicia 712 formed thereon in a recurring pattern. Furthermore, the indicia 712 formed on the weighted tape 710 is not necessarily associated with indicia formed on the corresponding club head. In this respect, while many of the previous embodiments of weighted tape discussed above includes indicia conforming to the logo formed on the club head, the indicia 712 formed on the weighted tape 710 shown in FIG. 10 is not limited thereto. Thus, the user may employ the weighted tape 710 in FIG. 10 for tuning the performance of the club head, while at the same time providing an interesting or more aesthetic look to the club head.
  • The weighted tape 710 generally includes a weighted layer 714 and an adhesive layer 716 which allows the weighted tape 710 to be attachable and conformable to a golf club head. In this respect, the weighted tape 710 may be attached to various locations on the golf club head. For instance, the weighted tape 710 may extend across only a portion of the rear surface of the club head, or alternatively, the weighted tape 710 may essentially form an external “skin” which is applied over a substantial portion of the rear surface of the club head.
  • According to one embodiment, the weighted layer 714 includes an inner surface 718 proximate the adhesive layer 716 and an exterior surface 720 opposite the interior surface 718, with the exterior surface 720 having indicia thereon that forms a repeating pattern. As used herein, the term “repeating pattern” refers to any pattern, design, logo, or other indicia which occurs more than once on the weighted layer 714. In the exemplary embodiment, the indicia 712 includes a quadrangular-type pattern 722 and several LOGOs 724 appearing in generally evenly spaced relation to each other between the lateral edges 726 of the tape 710, with each LOGO 724 being surrounded by the quadrangular-type pattern 722. The quadrangular pattern 722 is collectively defined by a plurality of raised surfaces 726 and a plurality of recessed surfaces 728. The LOGO may be associated with the club head (e.g., manufacturer of club head, loft of the club head, etc.), or not associated with the club head (e.g., golfer's initials/nickname, alumni logo, personalized design, etc.). The repeating pattern 722 may be embossed, stamped, forged, or otherwise formed into the weighted tape 710 using techniques known by those having ordinary skill in the art.
  • The weighted tape 710 may be sized and configured to correspond to a predetermined swing weight adjustment weight following application of the weighted tape thereto. In this respect, an analysis of the golfer's swing may reveal that a predetermined amount of weight attached to a certain location on the golf club head may improve the golfer's performance. It is contemplated that the weighted layer 714 may comprise at least one of lead, tin, bismuth, steel, ceramic, stone, pewter, tungsten, tungsten-nickel alloy, or other materials known by those skilled in the art. According to one particular implementation, the weight tape 710 comprises a density of no less than 4 g/cc, and more preferably, a density of no less than 7 g/cc, and still more preferably, a density of no less than 10 g/cc.
  • The adhesive layer 716 includes an adhesive which allows the weighted tape 710 to be selectively secured to an external surface of the golf club head. The adhesive may be an acrylic adhesive or other adhesive materials known by those skilled in the art. In one embodiment, the adhesive layer 716 simply includes a coating of adhesive applied to the interior surface 718 of the weighted layer 714, while in other embodiments, the adhesive layer 716 includes an adhesive body 730 having an external surface 732 to which the adhesive is applied. A peel-away layer 735 may cover the adhesive layer 716 prior to use to maintain the adhesive properties of the adhesive layer 716, and may be removed to expose the adhesive layer 716 immediately before placing the tape 710 on the golf club.
  • According to one embodiment, the weighted tape 710 is formed by attaching the weighted layer 714 to the adhesive layer 716. This may include coating the adhesive onto the weighted layer 714, laminating the adhesive layer 716 onto the weighted layer 714, adhering the adhesive layer 716 onto the weighted layer 714 or otherwise securing the adhesive layer 716 onto the weighted layer 714. The indicia 712 is formed in the weighted layer 714 so as to include the recurrent embossed pattern by roll forging a stock material using a patterned die 734. As shown in FIG. 10, the pattern die 734 includes a pair of rollers 736, with the tape 710 being advanced through the rollers 736 to impart the indicia 712 into the tape 710.
  • The weighted tape 710 may be formed in several different embodiments. In one embodiment, the weighted tape 710 includes a roll of tape, which may be cut or ripped to the desired length. In other embodiments, the weighted tape 710 is a sticker or appliqué specifically configured to fit onto the golf club head.
  • This disclosure provides exemplary embodiments of the present invention. The scope of the present disclosure is not limited by these exemplary embodiments. In this regard, while the system, methods, and apparatus of the disclosure have been described and illustrated primarily with respect to a weighted golf club, it will now be readily appreciated that articles other than golf clubs, such as hockey sticks, baseball/softball bats, lacrosse sticks, cricket bats, etc., may be configured as set forth herein, for example, with predefined regions comprising first branding indicia or recommended placement positions for weighted tape, which may also be branded as set forth herein. As such, numerous variations, whether explicitly provided for by the specification or implied by the specification, such as variations in structure, dimension, type of material and manufacturing process may be implemented by one of skill in the art in view of this disclosure.
