DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

(9) Illustrative embodiments of the invention are described below. The following explanation provides specific details for a thorough understanding of and enabling description for these embodiments. One skilled in the art will understand that the invention may be practiced without such details. In other instances, well-known 6 structures and functions have not been shown or described in detail to avoid unnecessarily obscuring the description of the embodiments.

(10) 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 or singular number respectively. Additionally, the words herein, above, 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 this application. When the claims use the word or in reference to a list of two or more items, that word covers all of the following interpretations of the word: any of the items in the list, all of the items in the list and any combination of the items in the list. When the word each is used to refer to an element that was previously introduced as being at least one in number, the word each does not necessarily imply a plurality of the elements, but can also mean a singular element.

(11) FIGS. 1 and 2 illustrate a game system 10 for playing on a horizontal surface 15, such as a ground surface outdoors, a floor surface indoors, or the like. A vertical pole 20 has a lower section 30 telescopingly fixed with an upper section 40. The lower section 30 and the upper section 40 are aligned along a common longitudinal axis L.sub.1. The lower section and upper section 40 are preferably made from a metal tube stock material, a relatively strong plastic or fiberglass material, or the like.

(12) The lower section 30 has a bottom end 32 adapted for fixing with a base 100. An upper end 38 of the lower section 30 is adapted for receiving the upper section 40 at a height 9 adjustment mechanism 50 (FIG. 4). The base 100 is adapted to engage the horizontal surface 15.

(13) The height adjustment mechanism 50 of the vertical pole 20 includes a cam lock lever 150 that, when in an engaged position, causes a cam 155 to press against the upper section 40 of the vertical pole 20 to lock the upper section 40 to the lower section 30, as is known in the art. When the cam lock lever 150 is in a released position the cam 155 retracts to allow the upper section 40 to be telescopingly adjusted with respect to the lower section 30. Alternately, other height adjustment mechanism 50 can be utilized, as 18 is known in the art. For example, the height adjustment mechanism 50 may include a rotationally actuated cam 160 that locks the upper section 40 to the lower section 30 when the upper section 40 is rotated in one direction with respect to the lower section 30. When the upper section 40 is rotated in an opposite direction, the upper section 40 is unlocked from the lower section 30.

(14) The base 100 in some embodiments includes a weight 110 (FIGS. 6-8) that includes a central opening 115 at a top end 118 thereof for receiving the bottom end 32 of the lower section 30 of the vertical pole 20. Such a weight 110 includes a flat bottom side 112 adapted for resting on the horizontal surface 15, and may include an outer plastic shell having an interior space for containing a relatively heavy material such as sand, water, or 6 the like.

(15) The base 100 in other embodiments includes a ground stake 120 having a central opening at a top send 128 thereof for receiving the bottom end 32 of the lower section 30 of the vertical pole 20. The ground stake 120 has a metallic ground-penetrating spike 124 at a bottom end 122 of the base 100 adapted for penetrating into the horizontal surface 15, such as an outdoor lawn, sand, dirt, or the like.

(16) The upper section 40 has a top end 48 with a rigid implement connector 60 (FIG. 3) adapted for receiving a playing implement 70 (FIG. 5). The upper section 40 further includes a bottom end 42 adapted for telescopic connection with the top end 38 of the lower section 30 at the height adjustment mechanism 50. In some embodiments the implement connector 60 includes a threaded aperture 61, the playing implement 70 including a cooperative threaded shaft 62. As such, the playing implement 70 is able to be screwed into the threaded aperture 61 of the top end 48 of the upper section 40 of the vertical pole 20. Alternately the playing implement 70 includes the threaded aperture 61 (FIG. 5) and the top end 48 of the upper section 40 includes the threaded shaft 62.

(17) A flexible tether 80, such as a nylon cord or the like, has an upper end 88 fixed with the playing implement 70, and a lower end 82 fixed with a sports ball 90. The sports ball 90 may be, for example, a tennis ball 200 (FIG. 1), a pickle ball 210 (FIG. 2), an American football 220 (FIG. 6), a golf ball 230 (FIG. 7), a baseball 240 (FIG. 1), a soccer ball 260 (FIG. 8), a tether ball (not shown), or the like.

(18) In preferred embodiments, the playing implement 70 includes a metallic coil spring 130 having a longitudinal axis L.sub.2 that is aligned with the common longitudinal axis L.sub.1 of the upper section 40 and the lower section 30 of the vertical pole 20. The coil spring 130 is adapted to receive a loop 140 at the upper end 88 of the tether 80. As such, the sports ball 90 can be hit in one direction to cause the loop 140 at the upper end 88 of the tether 80 to travel upwardly along the coil spring 130 as the sports ball 90 spins about the coil spring 130. When hit in an opposing direction, the sports ball 90 spins about the coil spring 130 in the opposite direction, causing the loop 140 to travel downwardly along the coil spring 130.

(19) In preferred embodiments of the invention, the playing implement 70 includes a metal, plastic, or fiberglass extension rod 170 that has a proximal end 172 adapted for fixing with the implement connector 60 of the upper end 48 of the upper section 40 of the vertical pole 20. A distal end 178 of the extension rod 170 is adapted for connecting with the upper end 88 of the tether 80. One or more hooks 190 (FIG. 6) can be included, fixed with the vertical pole 20.

(20) In such embodiments, preferably the extension rod 170 includes a rigid angle adjustment mechanism 180 comprising two radially ridged plates 185 that, when pressed together with a mechanical fastener 186, become rotationally locked together. When released by loosening the mechanical fastener 186, the two radially ridged plates may rotate with respect to each other. One of the plates 185 is connected with the implement connector 60, and the other plate 185 is connected with the proximal end 172 of the extension rod 170. Such an angle adjustment mechanism 180 is preferably made with injection molded plastic material.

(21) In some embodiments the game system 10 includes a swivel 250 (FIGS. 7 and 8) mounted proximate the bottom end 32 of the lower section 30 of the vertical pole 20. A second tether 255 may be fixed with the swivel 250 at a proximal end 252 of the second tether 255, the sports ball 90 being fixed with a distal end 258 of the second tether 255. As such, sports balls such as the golf ball 230 or the soccer ball 260 may be attached to the second tether 255 so that when struck, the sports ball 90 spins around the vertical pole 20.
