This disclosure relates generally to the field of grips for articles of sporting equipment having a gripping end, such as golf clubs and tennis rackets. In particular, the present disclosure relates to grips for incorporating one or more layers of material for displaying a decorative, textured, or informational design, and to methods for securing such layers to a grip. Still further, the disclosure relates to such grips including inserts for providing decorative, informational, or functional designs.
The grip provided on most sporting equipment having a gripping end, such as golf clubs, tennis rackets, and the like, provides cushioning and reduces slippage of the user's hands, thereby improving the user's enjoyment of the sport of choice. As illustrated in
The manufacturer may desire to display a design on the equipment, such as a corporate logo(s) and/or information regarding the equipment (make, model, size, etc.). Alternatively, the user may desire such a design for decorative purposes, to identify the equipment as belonging to the user, and the like.
Also, users desire large grips, for example, to accommodate the user's hand size and prevent the overlapping of the user's hands. As an example, it is well known to provide an oversized putter grip. However, increasing the size of the grip by simply increasing the thickness of, for example, the base 210 and/or a cushioning layer 220 undesirably greatly increases the weight of the grip as well, which may inhibit the user's performance in the sport of choice.
Accordingly, there remains a need in the art for grips including layers of materials, such as cushioning layers, design sheets, inserts, and/or combinations thereof, to provide grips of varying physical properties and optionally including designs which impart information, are decorative, and/or provide an additional functionality to the grip. Desirably, this is done in a fashion which does not significantly increase the assembled grip weight.
In accordance with the need identified in the art, in one aspect the present disclosure describes a grip for sporting equipment having a gripping end, comprising a grip base or underlisting adapted to receive the gripping end in an interior thereof. The grip base or underlisting may include at least one cavity defined in an exterior surface thereof, and configured to receive a layer of material, an insert, or the like therein. The interior perimeter of the cavity and the exterior perimeter of the layer of material, the insert, or the like may be substantially coincident. The insert or inserts may include a design of a decorative, textured, or informational nature. In another embodiment, the cavities and cooperating inserts may be disposed on the exterior surface of the grip base to define a decorative, informational, or functional design.
The grip base may define opposed grip end portions and a center portion, with each grip end portion defining a receiver adapted for receiving at least a portion of one or more layers substantially overlaying the center portion. Typically, the grip end portions will be fabricated of a durable material for protecting the at least one grip end from damage and may extend various lengths along the gripping end. The center portion and grip ends may define or partially define a portion of the at least one cavity.
The grip end portions and center portion may be separate elements, or may be a unitary construction. The center portion will typically define a cross section that is narrower or thinner than, for example, the one-piece grip shown in
Any suitable adhesive as is known in the art may be used to affix the grip base to the gripping end, to affix the one or more layers to the center portion and to affix the one or more layers to one another. Also or in the alternative, the center portion and the one or more layers may be manufactured of compatible materials such that heat and pressure bond them together.
Any material having the desired properties, such as where appropriate particular properties of durability, thickness, strength, shock absorption, cushioning, tackiness, and aesthetically pleasing appearance may be used in fabricating the grip base and the at least one insert. A number of suitable materials are well known in the art and are contemplated for use herein, such without intending any limitation as rubber, polymers, latex, natural or synthetic leathers, closed cell foams, open cell foams, natural material, synthetic material, or any other material currently used in fabricating grips for sports equipment.
Certain of the one or more layers/inserts overlaid on the grip base and/or placed in the at least one cavity may take any of a variety of forms, such as a hollow sleeve or cylinder, a planar sheet or block having two side edges, a top edge, and a bottom edge, or the like. Again, any material having the desired properties, such as where appropriate durability, thickness, strength, cushioning, shock absorption, tackiness, and aesthetically pleasing appearance may be used in fabricating any of the one or more layers/inserts, such as without intending any limitation polymers, closed cell foams, open cell foams, latex, rubber, natural or synthetic leathers, natural material, synthetic material, or any other material currently used in fabricating grips for sports equipment. A variety of such materials are well known in the art.
In addition, any of the one or more layers/inserts may be fabricated of any suitable lightweight material, such as without intending any limitation closed cell foams, open cell foams, polymers, or synthetic materials. As will be appreciated, the thickness of the layers/inserts formed of such a lightweight material may be increased without greatly increasing the weight of the grip, thereby allowing significant increases in the cross-sectional diameter of the grip without greatly increasing the weight of the grip. Any of the one or more layers/inserts, such as a layer to be disposed on top of any other layers attached to the grip base, may be fabricated of a suitable substantially transparent material to provide a protective surface for a design placed on the gripping surface while still allowing visualization of the design.
The grip end portions may include or define receivers adapted to receive at least a portion of at least one of the one or more layers, including but not limited to a flange, rim, projecting edge, lip, slant, groove, bevel, channel, slot, slit, notch, and the like. Advantageously, the receivers assist in preventing the leakage of adhesive from an area between the center portion and the one or more layers as well as from areas between the one or more layers. In addition, the receivers assist in protecting at least a portion of opposed edges of the one or more layers/inserts attached to the grip base from damage.
Still other aspects of the present invention will become apparent to those skilled in this art from the following description wherein there is shown and described a preferred embodiment of this invention, simply by way of illustration of one of the modes best suited to carry out the invention. As it will be realized, the invention is capable of other different embodiments and its several details are capable of modification in various, obvious aspects all without departing from the invention. Accordingly, the drawings and descriptions will be regarded as illustrative in nature and not as restrictive.
The accompanying drawings incorporated in and forming a part of the specification illustrate several aspects of the present invention and, together with the description, serve to explain the principles of the invention. In the drawings:

Reference will now be made in detail to the presently preferred embodiment of the invention, an example of which is illustrated in the accompanying drawings. In those drawings, for convenience, like features are labeled with like reference numerals.
In one aspect, the present disclosure provides a grip base 10 for sporting equipment having a gripping end. As illustrated in
The center portion 18 is located between the grip end portions 16a and 16b and is adapted for receiving the gripping end 12 in an interior thereof, as shown in
The receivers 17a and 17b may be adapted to receive a first layer of material, such as a layer 22 or 62, disposed over the center portion. In this manner, the receivers 17a and 17b assist in protecting opposed edges of the first layer from damage. The receivers 17a and 17b may take any form suitable to receive the first layer. Exemplary forms of the receivers 17a and 17b include, without limitation, a flange, rim, projecting edge, lip, slant, groove, bevel, channel, slot, slit, or notch. Non-limiting examples of embodiments of receivers 17a and 17b are shown in
As illustrated in
By selecting materials which provide the desired properties and applying same in multiple layers rather than as single solid pieces or fewer layers as conventionally done in the art, it is possible to provide a grip having desired properties without significantly increasing total weight. As a non-limiting example, a first layer 22 could be selected for a desirable property of durability, a second layer 32 could be selected for a desirable property of cushioning, and a third layer 94 could be selected for a desirable property of tackiness. By using these three layers, rather than a grip formed of a single piece of material or an underlisting and a single thick layer of material wrapped around that underlisting, properties of durability, cushioning, and tackiness can be imparted while still providing a finished grip of comparatively lesser weight.
Returning to
Also, a suitable adhesive may be coated onto an outer surface of the center portion 18 to affix the first layer, such as the layer 22, to the center portion 18. Alternatively, the adhesive may be coated onto an inner surface of the first layer, or onto both surfaces. Still further, the center portion or the first layer may be pre-coated with the adhesive during manufacture. Numerous suitable natural and synthetic adhesives are known in the art. In other embodiments, the center portion and the first layer may be manufactured of compatible materials such that application of sufficient heat and/or pressure cause them to form a bond. The first layer may then be placed on or wrapped around the center portion 18 and received in the receivers 17a and 17b. In this manner, the receivers 17a and 17b may assist in preventing the leakage of adhesive from an area between the first layer and the center portion 18.
A suitable adhesive may also be coated onto an outer surface of the first layer, such as the layer 22, onto an inner surface of the second layer, such as the layer 32, or onto both surfaces to affix the surfaces together. Alternatively, the first layer or the second layer may be pre-coated with the adhesive during manufacture. Again, numerous suitable adhesive substances are known in the art. In yet another embodiment, the layers may be manufactured of compatible materials such that heat and pressure bond them together. The second layer may then be placed over the first layer and received in the receivers 17a and 17b. In this regard, the receivers 17a and 17b may also assist in preventing the leakage of adhesive from an area between the second layer and the first layer.

The thickness of any of the layers may be varied in accordance with the needs of the user, i.e. in accordance with the user's hand size and preferred grip thickness.
In addition, any of the layers may be fabricated of any suitable lightweight material, such as closed cell foams, open cell foams, polymers (for example polystyrene or polyurethane), or synthetic foams. An elongated strip, such as the elongated strip with a locking mechanism as is described in the present inventor's U.S. Pat. No. 6,971,959 for a Grip for Sports Equipment, the entirety of which is incorporated herein by reference, may be used to provide one or more of the recited layers. As illustrated in
As will be discussed below, any of the layers/inserts also may be fabricated of a suitable substantially transparent or translucent material and used protect a design placed on the grip while still allowing visualization of the design. Typically, the substantially transparent layer would be positioned on top of any other layers forming the finished grip. Such a system is described in the present inventor's U.S. Pat. No. 6,718,675 for a Display Grip for Sports Equipment, the entirety of which is incorporated herein by reference.

Shown also in the drawing is a layer or insert 1140 having an exterior perimeter 1150 configured to be coincident with, or having substantially the same shape, as the interior perimeter 1120 of the cavity 1110 when assembled. Thus, the insert 1140 disposed in cavity 1110 will cover or overlay less than a full circumference of the grip base 1100. The insert 1140 may include one or more decorative and/or informational designs 1160 disposed thereon. As shown in
As non-limiting examples, the grip base 1100 and insert 1140 may be made of any suitable natural or synthetic material as are known in the grip manufacturing arts, such as rubber, cotton, polyurethane, thermoplastic polyolefin, thermoplastic resins, elastomers, and others. Of course, combinations of such materials are contemplated. In turn, particular combinations of materials for grip base 1100/insert 1140 may be selected for desired properties. Without intending any limitation, particular examples of combinations of materials for grip base 1100/insert 1140 could include rubber/polyurethane, thermoplastic polyolefin/polyurethane, thermoplastic resins/polyurethane, elastomers/polyurethane, rubber/elastomers, rubber/thermoplastic polyolefin, thermoplastic polyolefin/elastomers, and others.
Also, inserts 1140 may be unitary as shown in the drawings, or may be provided as two or more discrete layers of material (see layers 1140 a, b in
A substantially transparent top layer 32 (see
As shown in
A number of means for retaining inserts 1140 within cavities 1110 are contemplated. For example, any of a number of suitable adhesives are well known to the skilled artisan, and are contemplated for use herein. In another embodiment, the interior perimeter 1120 of cavity 1110 may include a flange 1165 (see

A single insert 1140 may be provided, on which may be disposed a decorative or informational design (see
Accordingly, the grip of the present invention provides several advantages over conventional grips. One or more of the inserts) 1140, particular layers of materials combined to form the insert(s) 1140, and the grip base 1100 may be made of a material of a lighter or greater weight, of a greater or lesser durability, or having a different texture or “feel,” allowing the grip to be manufactured to varying specifications by varying the nature of the insert(s) 1140 or the grip base 1100. Still further, providing a decorative, instructional, or functional design disposed on a separate insert 1140 allows the grip to be tailored to various desired appearances, weights, or other specifications. while reducing manufacturing cost and complexity. That is, fewer base or core configurations of grip base 1100 may be provided and altered by applying different inserts 1140, thereby providing finished grips having a wide variety of finished appearances and properties at reduced manufacturing cost. At the same time, the grip of the present invention does not compromise the desirable properties of the grip or prevent the display of information on the gripping area.
The foregoing description of a preferred embodiment of the invention has been presented for purposes of illustration and description. It is not intended to be exhaustive or to limit the invention to the precise form disclosed. Obvious modifications or variations are possible in light of the above teachings. For example, an end cap (not shown) may overlay an end of the grip base 1100 on the distal portion of gripping end 12, either before or after the grip 10 of the present invention is installed thereon, using a combination of adhesive and a friction fit as is known in the art. A rib and groove structure as is described in the present inventor's U.S. Pat. No. 6,718,675 for a Display Grip for Sports Equipment may also be used to secure the grip base 1100 to the end cap.
The embodiment described was chosen to provide the best illustration of the principles of the invention and its practical application to thereby enable one of ordinary skill in the art to utilize the invention in various embodiments and with various modifications as are suited to the particular use contemplated. All such modifications and variations are within the scope of the invention as determined by the appended claims when interpreted in accordance with the breadth to which they are fairly, legally and equitably entitled.
