[0040] In the following discussion that addresses a number of embodiments and applications of the present invention, reference is made to the accompanying drawings that form a part hereof, and in which is shown by way of illustration specific embodiments in which the invention may be practiced. It is to be understood that other embodiments may be utilized, and changes may be made without departing from the scope of the present invention.
[0041] Various inventive features are described below that can each be used independently of one another or in combination with other features. However, any single inventive feature may not address any of the problems discussed above or only address one of the problems discussed above. Further, one or more of the problems discussed above may not be fully addressed by any of the features described below.

As used herein, the term ‘about” means +/−5% of the recited parameter. All embodiments of any aspect of the invention can be used in combination, unless the context clearly dictates otherwise.
[0043] Unless the context clearly requires otherwise, throughout the description and the claims, the words ‘comprise’, ‘comprising’, and the like are to be construed in an inclusive sense as opposed to an exclusive or exhaustive sense; that is to say, in the sense of “including, but not limited to”. Words using the singular or plural number also include the plural and singular number, respectively. Additionally, the words “herein,” “wherein”, “whereas”, “above,” and “below” and words of similar import, when used in this application, shall refer to this application as a whole and not to any particular portions of the application.
[0044] The description of embodiments of the disclosure is not intended to be exhaustive or to limit the disclosure to the precise form disclosed. While the specific embodiments of, and examples for, the disclosure are described herein for illustrative purposes, various equivalent modifications are possible within the scope of the disclosure, as those skilled in the relevant art will recognize.
[0045] Referring to
[0046]
[0047] As best seen in front perspective view
[0048] The replaceable striking pad 101 is abrasion-resistant and firmly attached to the conventional iron golf club head 102 to protect the bottom sole 126 of the club head 102 from impact and abrasion damage when used on the hard surface. The shape of the replaceable striking pad 101 including the holding ledge 125 allows the club head 102 to snugly fit therein, yet still allows some side tilt adjustment to better accommodate variability in golf club heads and the golfers' natural contact angle with the ground. The face of the replaceable striking pad 101 further fits the golf club head 102 to provide the correct club face angle for contacting the spiked ball 110.
[0049] The replaceable striking pad 101 is preferably made from a material with high toughness, good wear resistance, and relatively low coefficient of friction. In some embodiments, the striking pad is made from a material with high toughness with ISO 179 Charpy notched impact of greater than 10 kJ/m at 23 degrees C., high wear resistance and a dynamic coefficient of friction less than 0.5 when tested on steel. For example, the material of the replaceable striking pad 101 can be selected from a group including, but not limited to, engineering plastics such as impact modified nylon, polypropylene block copolymer, and high molecular weight polyethylene.
[0050] The replaceable striking pad 101 is firmly attached to the golf club head 102 via the removable clamps 105 with suitable bolts 103 and nuts 106, or other fasteners can be used. Referring to
[0051] The preferred golf club head 102 for street golf is an iron style club. Wood or hybrid style clubs may also be used. In an alternative embodiment of the invention, the striking pad 101 for wood or hybrid clubs extends over the top of the clubs and clamps around the back lobe of the clubs in the same manner as the striking pad 101 for iron club clamps around the top and upper back of the face of the iron club head 102 according to the preferred embodiment.
[0052]
[0053] The replaceable striking pad 101 set in this manner resists the drag forces on the bottom end 122 of the striking pad 101 when in contact with the street or hard surface. The striking pad 101 protects the club head 102 and the street from damage when street golf is played. The striking pad 101 is designed to be simple and easy to replace when needed due to wear.
[0054]
[0055]
[0056] Referring to
[0057] A sufficient number of the plurality of spikes 127 oriented as uniformly as reasonably possible consistent with manufacturing limitations around the ball core provides smooth and straight rolling character. Providing spikes with circular cross sections further enhances the smooth rolling characteristics of the ball. When the spiked ball 110 is rolling, the plurality of flexible spikes 127 also absorbs some of the irregularities in the asphalt or other slightly uneven surface to provide smooth rolling character. Thus, in this manner, the spiked ball 110 provides the functionality of both the ball and the grass experienced at a golf course, with the spikes on the ball simulating the effect of grass on the roll and bounce of the ball.
[0058] Turning to
[0059]
[0060] Prototype testing on an adjustable inclined plane surface provides a measure of slope holding performance allowing spike dimensions and material modulus selection to be modeled to provide ball designs with the desirable properties. Spike buckling also provides additional cushion to protect cars and other urban objects from damage when inadvertently struck by the spiked ball.
[0061] Some amount of bounce upon landing is desirable to simulate the typical 0.5 to 3-meter range of first bounce height of golf balls on courses proportioned to flight distance. One embodiment exhibits 25% to 50% rebound when dropped a meter onto a hard surface. In other embodiments less than 25% or more than 50% rebound occurs. For the street golf game, the spiked ball 110 may be swapped in place by players to provide preferred characteristics for each shot in the same manner as clubs are selected for each shot on a conventional golf course.
[0062] The spiked ball 110 of the present invention provides an improved travel distance and controlled rolling resistance to lessen the instances of the spiked ball 110 ending up in gutters, drains, and rolling away down sloped streets. The spiked ball 110 has more abrupt stopping from a low velocity to enable better ball placement and gives better bounce and rebound when landing from an airborne trajectory than a foam-covered ball would have. Moreover, the spiked ball 110 provides a straighter rolling direction and less chatter and small scale bouncing when rolling on an uneven surface such as asphalt.
[0063] Referring to
[0064] The portable ball trap 117 for the street golf game of the present invention provides a preferably portable trap 117 which can be easily positioned on any surface and effectively captures the ball 110 hit into its effective capture diameter. The thin flat platform 112 of the portable ball trap 117 provides a nearly flat approach path, both for level placement of the portable ball trap 117 on the street surface and to impart a minimal effect on the ball trajectory as it nears the portable ball trap 117. The portable ball trap 117 preferably traps the spiked ball 110 using a minimal amount of the ball's translational energy while assuring a secure trapping and also does not distort the ball trajectory or cause a backward rejection style reaction to the entered ball 110.
[0065]
[0066] The optional remotely controlled vehicle 115 allows for ease of playing and simulating the game of golf by positioning the portable ball trap 117 remotely. Using the remotely controlled vehicle 115 for portable ball trap 117 placement allows the players to set the location of the next ball trap 117 at some suitable distance down the street and in conditions with the desired degree of challenge. After the players have completed the game in a particular location, the next location can be set remotely in a like manner without having to walk down the street and back, to place the portable ball trap 117 manually. This allows for unique pathways and course layouts through a neighborhood each time the game is played. Navigating the remotely controlled vehicle 115 with the portable ball trap 117 down the street using the remotely controlled vehicle 115 is fun, sometimes challenging, and adds to the overall enjoyment of the game. The portable ball trap 117 can also be driven onto the sidewalk or other accessible areas to provide more variety.
