DETAILED DESCRIPTION

Reference will now be made in detail to some embodiments of the invention, examples of which are illustrated in the accompanying drawings.



FIG. 1 shows a top perspective view of a novel tic-tac-toe game apparatus 10, referred to here as the “OXO Game”. The game apparatus 10 includes a base member 11, nine X-shaped pop-up elements 101-109, nine O-shaped pop-up elements 110-118, nine circular-shaped elements 119-127, and eighteen spring-loaded retractable click mechanisms. Only two of the spring-loaded retractable click mechanisms are seen from the perspective of FIG. 1. The X-shaped pop-up element 103, the O-shaped pop-up element 112, and the circular-shaped element 121 have been removed in the illustration of FIG. 1 so that the spring-loaded retractable click mechanisms 128 and 129 are revealed. Spring-loaded retractable click mechanism 128 is the click mechanism for X-shaped pop-up element 103. Spring-loaded retractable click mechanism 129 is the click mechanism for O-shaped pop-up element 112. There is at least one spring-loaded retractable click mechanism for each of the pop-up elements.


The base member 11 has a thickness that is at least as thick as the height of one of the pop-up elements. The upper surface 12 of the base member 11 is substantially planar and extends in a plane, referred to here as the “base member plane”. There are nine shallow cylindrical openings that extend downward into the base member 11 from the upper surface 12. Reference numeral 130 identifies one of these shallow cylindrical openings. In each of these shallow cylindrical openings is disposed a corresponding O-shaped pop-up element and a corresponding X-shaped pop-up element. Each pop-up element can be in a pressed-down state or can be disposed in a popped-up state.


When a pop-up element is in its pressed-down state, then the body of the pop-up element is either entirely or substantially disposed below the base member plane of the upper surface of the base member. The upper surface of the pop-up element is planar. In this state, the upper surface of the pop-up element is in the plane of the base member plane of the upper surface of the base member.


When a pop-up element is in its popped-up state, then the body of the pop-up element extends upward with respect to the base member so that more of pop-up element protrudes above the base member plane of the base member as compared to how much of the pop-up element protrudes above the base member plane when the pop-up element is in the pressed-down state.


Each of the O-shaped pop-up elements can be in its pressed-down state, or can be in its popped-up state. For example, O-shaped pop-up element 117 is shown in its pressed-down state, whereas O-shaped pop-up element 116 is shown in its popped-up state. Likewise, each of the X-shaped pop-up elements can be in its pressed-down state, or can be in its popped-up state. For example, X-shaped pop-up element 108 is shown in its pressed-down state, whereas X-shaped pop-up element 107 is shown in its popped-up state.


A user can cause a pop-up element to toggle between its pressed-down state and its popped-up state by pressing down and then releasing the pop-up element. Each time the pop-up element is pressed down and released, its final resting position changes state. If the prior state of the pop-up element was the pressed-down state, then a pressing and releasing of the pop-up element causes the pop-up element to move to the popped-up state. Similarly, if the prior state of the pop-up element was the popped-up state, then a pressing and releasing of the pop-up element causes the pop-up element to move to the pressed-down state.


Unlike the O-shaped and X-shaped pop-up elements, each of the circular-shaped elements 119-127 remain on the same plane as the base member plane and cannot be popped-up or pressed-down. The circular-shaped elements help maintain vertical alignment of the O-shaped and X-shaped pop-up elements when sliding up and down with respect to the base member 11.



FIG. 2 shows a perspective view of one of the spring-loaded retractable click mechanisms 128 (used with the O-shaped pop-up elements). The spring-loaded retractable click mechanism 128 comprises a cam 132, a spring 133, a pin 134, a lower barrel 135 and an upper barrel 136. Similarly, the spring-loaded retractable click mechanism 129 (not shown) is used with the X-shaped pop-up elements.


The cam 132 has a cylindrical shape with teeth along the bottom that engage with the teeth located on the upper barrel 136 (see FIG. 4). The cam 132 also has a plurality of notches 137 that have a cross-sectional area that is substantially similar to the cross-sectional area of a plurality of slide guides 138 of the lower barrel 135 (see FIG. 3). This is to allow the cam 132 to slide along the vertical axis of the lower barrel 135 while still being able to engage the teeth of the upper barrel 136 (see FIG. 4). On the upper end of the cam 132 is a hole 139 having a diameter that is larger than the diameter of the upper end of the pin 134 but smaller than the diameter of the spring 133. This is to allow the cam 132 to compress the spring 133 while also being aligned along the pin 134.


The spring 133 in its expanded form has a length greater than the height of the cam 132, pin 134, and lower barrel 135. The spring 133 is placed inside the interior of the cam 132. Next, the spring 133 is placed on top of the pin 134. The diameter of the upper end of the pin 134 is smaller than the diameter of the spring 133. The diameter of the lower end of the pin 134 is larger than the diameter of the spring 133. Then, the cam 132, the spring 133, and the pin 134 slide into the lower barrel 135. The bottom of the lower barrel 135 is connected to the base member 11 in the bottom of the opening 130 (see FIG. 1).


Once the cam 132, the spring 133, and the pin 134 have been slid into the lower barrel 135, the upper barrel 136 is slid into the lower barrel 135. The teeth of the upper barrel 136 engage with the teeth of the cam 124 resulting in an extended position and a retracted position of the click mechanism 119.


In the example shown in FIG. 1, the click mechanism of the X-shaped pop-up element 107 in its extended position. The X-shaped pop-up element 107 protrudes above the plane of the upper surface 12 of the base member 11. In the example shown in FIG. 1, the click mechanism of the X-shaped pop-up element 108 is in its retracted position. The X-shaped pop-up element 108 does not extend above the plane of the upper surface of the base member 11 but rather the planar upper surface of the X-shaped pop-up element 108 is in the plane of the upper surface 12 of the base member 11.



FIG. 3 is another diagram of the cam 132 and the lower barrel 135. The cam 132 has a plurality of notches 137 that have a cross-sectional area that is substantially similar to the cross-sectional area of a plurality of slide guides 138 of the lower barrel 135. The plurality slide guides 138 significantly limit the cam 132 from rotating on along the horizontal axis. The lower barrel 135 can be part of the spring-loaded click mechanism 128 or 129. In yet another example, there are more or less slide guides 138 with different shapes that are substantially similar to the notches 137 on the cam 132.



FIG. 4 shows a perspective view of teeth from an upper barrel sliding against teeth from a cam. The upper barrel 136 has teeth along its lower end. The cam 132 has teeth that face in the opposite direction of the teeth on the upper barrel 136 of the upper barrel 136 interlock with the teeth of the cam 132. This is to allow the cam 132 to translate linear motion into rotational motion.



FIG. 5 shows a top perspective view of the gaming device. In this example, the O-shaped pop-up element 116 is shown from its top-perspective view. Additionally, the circular-shaped element 126 is shown from its top-perspective view. Furthermore, the X-shaped pop-up element 109 is shown from its top-perspective view.



FIG. 6 shows different views of the gaming device components. The circular-shaped element 122 is placed on top of the X-shaped pop-up element 103, which is placed on the O-shaped pop-up element 112, which is then placed in the opening 130. The circular-shaped element 122 has a hollow X-shaped section similar to the shape of the X-shaped pop-up element 103.


The circular-shaped element 122 comprises the first layer. The circular-shaped element 122 has four legs 140 on its bottom surface. Each leg 140 has a height such that the circular-shaped element 122 is in the same plane as the upper surface 12 of the base member 11. The cross-sectional area of each leg 140 is smaller than the cross-sectional area of each leg hole 144 in the O-shaped pop-up element. This is to allow the legs 140 of the circular-shaped element to slide through the leg holes 144 in the O-shaped pop-up element. Each leg 140 fits into a slot 131 within the opening 130 of the base member 11. This is to prevent the circular-shaped element from rotating or moving while at the same time help maintain the vertical alignment of the X-shaped and O-shaped pop-up elements.


The second layer is the X-shaped pop-up element 103. The bottom surface of the X-shaped pop-up element has an upper barrel 136, two feet 141, and an opening 142. The feet 141 are at a height such that the X-shaped element is in the same plane as the upper surface 12 of the base member 11 when the click mechanism 128 is in the pressed-down state. The cross-sectional area of each foot 141 is wider than the hollow cross-sectional area of the circular-shaped element 122. This is to prevent the X-shaped pop-up element 103 from completely exiting through the top of the circular-shaped element 122 when in the popped-up state. The cross-sectional area of each foot 141 is smaller than the cross-sectional area of the foot holes 145 in the O-shaped pop-up element.


The upper barrel 136 on the X-shaped pop-up element is for the spring-loaded retractable click mechanism 129. The upper barrel 136 and one of the feet 141 are able to fit within the top right hole 145 of the O-shaped element. In addition, an opening 142 is located on the bottom surface of the X-shaped pop-up element 103. The opening 142 is shallow and can fit around the upper barrel 136 of the O-shaped pop-up element 112. This allows the X-shaped pop-up element to be in the same plane as the upper surface 12 of the base member 11 when in the pressed-down state.


The third layer is the O-shaped pop-up element 112. In the example shown in FIG. 6, the bottom surface of the O-shaped pop-up element 112 has a plurality of holes (e.g.—leg holes 144 and foot holes 145), an upper barrel 136, and a plurality of posts 143. The plurality of posts 143 support the upper surface of the O-shape element. There are four leg holes 144 that are lined up with the four slots 131 in the opening 130 of the base member 11. The leg holes 144 are also used to keep the legs 140 of the circular-shaped element in place.


The fourth layer is one of the nine shallow cylindrical openings 130 that extend downward into the base member 11 from the upper surface 12. Within the opening are four slots 131 that are used to keep the legs 140 of the circular-shaped element 122 in place. Within the opening 130 are two spring-loaded retractable click mechanisms 128 and 129.



FIG. 7 shows a bottom perspective view of the gaming device. In this example, the gaming device uses a plurality of screws 150 along each edges of the bottom surface to secure the bottom surface to the base member 11. In another example, the gaming device uses a different number of fasteners or different types of fasteners.
