Abstract
Description
- This application is a continuation of U.S. patent application Ser. No. 15/401,963, filed Jan. 9, 2017, and issuing as U.S. Pat. No. 9,937,398 on Apr. 10, 2018, which is hereby incorporated by reference in its entirety.
- Conventional golf tees have stems designed to be pressed into the ground and ball-supporting heads that are designed to support an elevated golf ball during a tee shot. Typically, the ball-supporting head of the golf tee includes a concave surface that contacts the golf ball when the golf ball is placed on the tee. During a tee shot, friction between the concave surface and an outer surface of the golf ball may affect the spin of the golf ball, which may cause an uncontrollable or undesirable flightpath. It may therefore be advantageous to provide a golf tee with a head having enhanced surface properties to limit unintentional spin.
- In one aspect, the present disclosure provides a golf tee having a shaft with a top end and a bottom end. A cup may be located at the top end of the shaft, the cup having a concave surface, and the cup having a rim configured to contact a ball when the golf tee supports the ball. At least one protrusion may extend from the concave surface of the cup, the protrusion having a surface configured to contact the ball when the golf tee supports the ball.
- A stem may be located at the bottom end of the shaft, where the stem includes a material that is different than a material of the shaft. The stem may have a central elongated shaft and at least one column extending from the elongated shaft and configured to engage the ground. An end of the at least one column may include a concave notch.
- The bottom end of the shaft may include a flat surface, the flat surface being parallel to an axis defined by the shaft. A central portion of the shaft may have a circular cross-sectional shape with at least one indentation extending around the circular cross-section.
- At least a portion of the rim may be located a first distance from an axis defined by the shaft, where the at least one protrusion is located a second distance from the axis defined by the shaft, and where the first distance is greater than the second distance.
- The concave surface may be configured such that a gap is located between the concave surface and the golf ball when the golf tee supports the golf ball.
- In another aspect, a golf tee may include a shaft having a top end and a bottom end. A first support surface may be configured to contact a ball when the golf tee supports the ball. A second support surface configured to contact the ball when the golf tee supports the ball, where the first support surface is located a first distance from an axis defined by the shaft, where the second support surface is located a second distance from the axis defined by the shaft, and where the first distance is greater than the second distance.
- The first support surface may be defined by a rim of a cup located at the top end of the shaft, where the cup has a concave surface facing away from the shaft. The second support surface may be defined by a protrusion extending from the concave surface of the cup. A diameter of the rim may be at least 0.50 inches.
- The golf tee may further include a stem located at the bottom end of the shaft, where the stem includes a material that is different than a material of the shaft. The stem may include a central elongated shaft and at least one column extending from the elongated shaft and configured to engage the ground. An end of the at least one column includes a concave notch.
- The bottom end of the shaft may include a flat surface, the flat surface being parallel to an axis defined by the shaft. A central portion of the shaft may have a circular cross-sectional shape.
- In another aspect, the present disclosure provides a method including forming a shaft having a top end and a bottom end, forming a cup located at the top end of the shaft, the cup having a concave surface, and the cup having a rim configured to contact a
ball 200 when the golf tee supports the ball, and forming at least one protrusion extending from the concave surface of the cup, the protrusion having a surface configured to contact the ball when the golf tee supports the ball. - The method may also include forming a stem and locating the stem at the bottom end of the shaft. Locating the stem at the bottom end of the shaft may include inserting the stem in a mold before or during an injection molding process, wherein the injection molding process forms the shaft.

FIG. 1A shows a top perspective view of agolf tee 100 in accordance with the present disclosure.FIG. 1B shows a side elevation view of thegolf tee 100 ofFIG. 1A ,FIG. 1C shows a top view of thegolf tee 100 ofFIG. 1A , andFIG. 1D shows a bottom view of thegolf tee 100 ofFIG. 1A . Referring toFIGS. 1A-1D , thegolf tee 100 may include ashaft 102 having atop end 104 and abottom end 106. Theshaft 102 may be formed of any suitable material. In some embodiments, theshaft 102 may be a thermoplastic elastomer (TPE), and may be formed during an injection molding process. The material forming theshaft 102 may be flexible such that theshaft 102 can flex when struck by a golf club, for example, and it may be resilient such that theshaft 102 recoils or springs back into its unstressed shape after bending, stretching, or being compressed. Theshaft 102 may include one or more of the depictedindentations 108 extending at least partially around theshaft 102. Theindentations 108 may facilitate the bending, stretching, and/or compressing of theshaft 102. - A
cup 110 may be located at thetop end 104 of theshaft 102. The cup may be formed integrally and with the same material as theshaft 102, or alternatively thecup 110 may be formed separately from theshaft 102 and then attached to thetop end 104 of theshaft 102 with a suitable attachment means (such as by screwing, with an adhesive, etc.). Thecup 110 may have aconcave surface 112, as shown. Theconcave surface 112 of thecup 110 may face away from theshaft 102 and may be configured to face a surface of a ball (e.g., a golf ball, not shown inFIGS. 1A-1D ) when the ball is placed on thegolf tee 100. As described in more detail below, at least oneprotrusion 118 may be located in thecup 110 on theconcave surface 112. -
FIG. 1E shows a cross-sectional view of thegolf tee 100 ofFIGS. 1A-1D as it may appear when supporting agolf ball 200. As shown inFIG. 1E , therim 114 of thecup 110 may be configured (e.g., sized and shaped) such that when the ball is placed in contact with thegolf tee 100, therim 114 contacts theball 200. For example, when theball 200 is spherical, therim 114 may be circular, and may contact theball 200 at locations where the outer surface of theball 200 intersects a plane, the plane being perpendicular to alongitudinal axis 124 of theshaft 102. - In some embodiments, at least a portion of (and potentially all of) the
concave surface 112 may be spaced apart from theball 200 when theball 200 rests on therim 114. In other words, when theball 200 rests on therim 114, a space orgap 116 may be located between theconcave surface 112 and the surface of the ball. The space orgap 116 may be advantageous for reducing friction between thetee 100 and thegolf ball 200 with respect to a traditional golf tee where a substantially larger surface area typically contacts the outer surface of theball 200. Additionally or alternatively, as shown, at least oneprotrusion 118 may extend from theconcave surface 112 of thecup 110. Theprotrusion 118 may be configured (e.g., sized and shaped) such that it contacts theball 200 when theball 200 rests on therim 114. - Any number of protrusions may be included. In an exemplary embodiment, the
golf tee 100 may include eight (8) protrusions of equal length and arranged in a circular pattern (shown best inFIG. 1C ) such that each of theprotrusions 118 contacts theball 200 when theball 200 rests on the rim 114 (as shown inFIG. 1E ). More or less protrusions may be included (such as, for example, from about one (1) protrusion to about twenty (20) protrusions). It is also contemplated that theprotrusions 118 could be arranged in a pattern other than a circular pattern and/or at different heights on the concave surface 112 (which may requiredifferent protrusions 118 to have different dimensions). The protrusions may have any suitable shape, and therefore may be hemispherical, cylindrical, rectangular, triangular, pyramid-shaped, or the like. - Referring to
FIG. 1C andFIG. 1E , therim 114 may include afirst support surface 120 configured to contact aball 200 when thegolf tee 100 supports the ball, and theprotrusions 118 may define at least onesecond support surface 122 configured to contact theball 200 when thegolf tee 100 supports the ball. Thefirst support surface 120 may be a first distance from alongitudinal axis 124 defined by theshaft 102, such as about 0.37 inches in one non-limiting embodiment. Thesecond support surface 122 may be located a second distance from thelongitudinal axis 124 defined by theshaft 102, and the second distance may be less than the first distance. For example, in an exemplary embodiment, the radius (or other distance from the axis 124) of thefirst support 120 surface may be about 0.75 inches, and the radius (or other distance from the axis 124) of thesecond support surface 122 may be about 0.4 inches. In other words, thesecond support surface 122 may be closer to theaxis 124 than thefirst support surface 120. - In the depicted embodiment of
FIGS. 1A-1E , thesecond support surface 122 is formed by theprotrusions 118, but it is also contemplated that another suitable structure may be formed on theconcave surface 112 to form thesecond support surface 122. For example, an inner ring or rim (which may be a continuous ring or rim circling the axis 124) may be formed on theconcave surface 112. Such an embodiment may be advantageous for providing additional support to for a golf ball and/or for simplicity during manufacturing. Similarly, it is contemplated that thefirst support surface 120 may be formed by a structure other than a rim 114 (such as, for example, a plurality of outer protrusions). - Advantageously, the
golf tee 100 may have awider rim 114 than traditional golf tees, which may provide enhanced support of a ball. For example, therim 114 may have a diameter of at least 0.50 inches, at least 0.60 inches, at least 0.70 inches, at least 0.80 inches, at least 0.90 inches, or at least 1.00 inches (or greater). In one non-limiting exemplary embodiment, the diameter of therim 114 may be about 0.74 inches. Simultaneously, the weight of the ball may be distributed over several contact surfaces such that the static friction force is reduced at each specific contact point. Further, since theconcave surface 112 of thecup 110 is spaced from the ball, the total surface area of contact between theball 200 and thegolf tee 100 may be reduced when compared to a traditional tee. The sum of these characteristics may provide reduced spin (i.e., sidespin, backspin, topspin) resulting in longer, more controllable golf shots with fewer unintentional hooks and slices. - Referring back to
FIG. 1A , thetee 100 may include a stake or stem 126 extending from thebottom end 106 of theshaft 106. In one non-limiting embodiment, thestem 126 may have a length of about 1.25 inches, though other lengths are also contemplated. Thestem 126 is preferably configured to be pressed into the ground by a golfer, and may include a sharpenedtip 128 for the facilitation of entry into the ground. Thestem 126 may include a material that is different than a material of theshaft 102, and thestem 126 may be attached to theshaft 102 when theshaft 102 is molded, such as by injection over-molding (e.g., a portion of thepre-formed stem 126 may be inserted into a mold during the injection molding process for forming the shaft 102). Other suitable attachment means may also be used (e.g., the use an adhesive). Alternatively, theshaft 102 and thestem 126 may be formed integrally, such as during a single molding process, for example. - The
stem 126 may include anelongated body 130 and at least one optional fin orcolumn 132 extending radially outward from theelongated body 130. Thecolumn 132 may be configured to engage the ground, and may be advantageous for giving the stem 126 a relatively large surface area and a geometry suitable for providing a high degree of ground engagement and support. Any number ofcolumns 132 may be included. For example, fourcolumns 132 may be included (as best shown inFIG. 1D ), but stems with more or less columns are also contemplated. Thecolumns 132 may extend along the entirety of the length of thestem 126, or only along a portion of the length. When compared to a stem without columns, thestem 126 may be relatively secure when placed in the ground such that thestem 126 provides a relatively high resistance to movement and/or rotation of thestem 126 during a golf shot. To further enhance the desirable characteristics of thecolumns 132, eachcolumn 132 may include anotch 134 at its outer edge to provide additional surface contact and engagement between thecolumn 132 and the ground. - In some embodiments, the cross-section of
shaft 102 may vary along its length. As shown inFIG. 1A , acentral portion 140 of the shaft may include a circular cross section, which may be advantageous for providing suitable bendability and/or flexibility in all directions, for example. Thebottom end 106 of theshaft 102 may be shaped with a different cross-section (e.g., with a rectangular cross-section) to include at least one flat surface, such as the depictedflat surface 136. Theflat surface 136 may be parallel to the longitudinal axis of theshaft 102, though this is not required. Theflat surface 136 may be advantageous for providing an area to place alogo 138 and/or another mark for decorative purposes and/or to provide information to a golfer, such as information conveying the company marketing thegolf tee 100, the type and/or size of thegolf tee 100, etc. The logo or other mark may be stamped, pressed, printed, molded, or may a portion of an over-molded component that extends to thesurface 136, such as an over-molded stem or stake. In one exemplary, non-limiting embodiment, thesurface 136 may be rectangular with a width of approximately 0.60 inches and a height of approximately 0.30 inches. -
FIG. 2 shows four embodiments of a golf tee in accordance with the present disclosure, where each of the four embodiments has a different shaft length. For example (and without limitation), thefirst golf tee 300 may have a shaft length of about 2.25 inches, the second golf tee 400 may have a shaft length about 1.75 inches, the third golf tee 500 may have a shaft length of about 1.25 inches, and thefourth golf tee 600 may have a shaft length of about 0.50 inches. Providing golf tees with different shaft lengths may be advantageous to accommodate for multiple types of golf shots and/or for multiple swing types. Thetees - Referring to
FIG. 3 , it is contemplated that a golf tee 700 may include protrusions 726 (or other elements forming a contact surface) that have dimensions such that thegolf ball 200 does not contact arim 714 of the golf tee 700 at all. This may be advantageous for further reducing the surface area of contact between thegolf ball 200 and the tee 700 with respect to other embodiments. Therim 714, though not in constant contact with theball 200, may be relatively close to thegolf ball 200 such that it may assist (e.g., briefly contact the ball) when placing thegolf ball 200 on thetee 300. Optionally, the golf tee 700 may include asecond protrusions 727 located further from the axis than theprotrusions 726. Thesecond protrusions 727 may form a support surface for contacting theball 200, and may be included in combination with any of the embodiments and/or aspects described herein. - Specific embodiments of a golf tee have been described for the purpose of illustrating the manner in which the aspects of the present disclosure are used. It should be understood that the implementation of other variations and modifications of the embodiments described herein and their various aspects will be apparent to one skilled in the art, and that the invention is not limited by the specific embodiments described.
