FIELD OF THE INVENTION
This invention is in the general field of gaming equipment, and more particularly convertibile gaming equipment for playing different types of table games.
BACKGROUND OF THE INVENTION
The table games of ping-pong and pool (including billiards) each require a special playing surface which is solidly supported off the floor. Given the different nature and requirement of the games, the tables are constructed in dedicated form, which although functional occupies the maximum amount of space if both games are to be available. Another disadvantage of such games is the size and mass of the required tables, which renders them rather permanent and immovable. Ping-pong tables are made to fold, with the fold line concealed directly below the net. A pool or billiards table cannot practicably be made to fold because a fold line would disrupt the playing surface.
These games also require pieces and playing equipment which are preferably kept in close proximity to the table. A number of different type of racks and storage devices have been made for this purpose, but this does not result in self-containment of all of the necessary game equipment with the table.
SUMMARY OF THE INVENTION
The present invention provides a novel convertible game table for ping-pong and pool or billiards. The convertible game table of the invention has a stable foundation which supports combined but separate planar table top game playing surfaces. The table top game playing surfaces are surrounded by a frame and are otherwise structurally combined. In one embodiment, a game table top has first and second game playing surfaces for pool and ping-pong respectively surrounded by a frame, and a structural member between them. The game table top is mounted upon a base with one of the game playing surfaces supported in a horizontal upright playing position, and can be selectively repositioned with the other game playing surface in the horizontal upright playing position.

DETAILED DESCRIPTION OF PREFERRED AND ALTERNATE EMBODIMENTS
As shown in the form of a first embodiment in FIGS. 1 and 2, a convertible game table of the invention, indicated generally at 10, has a convertible table top 12 and a foundation or base 14 which has a frame 141 on which the convertible table top is mounted. The convertible table top 12 is rectangular with a surrounding frame 121 which forms a vertical side wall 122 around a perimeter of the table top. Within the frame 121 there is a planar table top game playing surface, such as surface 123 shown in FIG. 1 as a pool or billiards playing surface, or surface 124 as shown in FIG. 2 as a ping-pong playing surface, with a transversely mounted net 1240 upon posts 1241. The table top frame 121 is mounted to the base frame 141 by spindles or pins 133, 134 which are axially aligned at opposite ends of the table 12 as shown. A locking mechanism is provided between the table top 12 and the frame 141 to secure the table top 12 in one of the horizontal playing positions as shown in FIG. 2. As shown in FIG. 9, one type of locking mechanism is incorporated into one or both of the pins 133, 134, which can be axially translated within a keyway 1345 from a shaft position in which the table top 12 can rotate about the shaft 1331 of the pin, to a keyed locked position in which a keyed lock 1332 prevents rotation of the table top 12 relative to the base frame 141. In the keyed locked position, the planar lock 1332 extends between the base frame 145 and the table top frame 122 to prevent rotation. Other locks can be provided in combination with those of the pins 133, 134, such as any type of fasteners between the table top frame 122 and the surrounding base frame 145. To change the orientation of the table top from the pool table surface 123 being upright to the ping-pong table surface 124 being upright, the pins are translated to the unlocked rotating position and the table top 12 is simply rotated 180 degrees about the pins 133, 134, and the pins thereafter locked into the non-rotating position. Because the pins 133, 134 are bearing directly upon the frame 145 of the base 14, it is not necessary to lift the table top 12 off of the base 14 in order to change the orientation of the table top 12.
To provide a mounting structure for the bumpers 125 which surround the pool or billiards surface 123, the frame 121 extends vertically beyond the playing surface 123. by this construction, the playing surface 123 is recessed from a top edge 126 or surface of the frame 121. Each of the ball pockets 127 located at the comers and midpoints of the playing surface 123 have an associated receiving compartment 128 as shown, into which the balls 129 travel from the associated pocket 127. Access openings 130 are provided to each of the receiving compartments 128 through which the balls 129 can be retrieved for replacement upon the playing surface 123. Although receiving compartments 128 are illustrated with each of the ball pockets 127, alternative embodiment do not require this arrangement for each ball pocket. In another alternative, the ball pockets 127 may be sized to accommodate more than one ball 129 such that the pockets 127 also serve as ball storage compartments. For storage and retention of the balls 129 in the receiving compartments 128 or pockets 127, each are provided with respective covers 132 and 131 as shown in FIG. 3 to effectively retain the balls regardless of the orientation of the table, as further described.
An alternate embodiment of the convertible game table 10 of the invention is illustrated in FIGS. 3 and 4, wherein the table top 12 is supported by the base 14. The base 14 includes four or more vertically oriented legs 144 and a mounting frame 145 on which the table top frame 121 rests or is otherwise engaged. In this embodiment, the table top 12 can be removed from the base 14 by, for example, simply lifting it entirely and flipping it to change the playing surface 123 or 124 to be in the upright position for play, or for example by insertion of a rod 146 through an axis of the table top as shown to provide an axis about which the table top can be rotated to change its orientation, as shown in FIG. 3. This can be easily done by two people. The rod 146 extends along a longitudinal axis in a center area of the table top 12 between the surfaces 123 and 124. Although the rod 146 is illustrated as running the entire length of the table top 12, an alternate embodiment of this aspect of the invention is contemplated wherein shorter segment gripping rods are provided at each end of the table top for purposes of gripping and re-orienting the table top 12 as described. As shown in FIG. 4, the posts 1241 of the ping-pong net can be used to register the table top 12 in alignment with the base frame 145 by insertion into corresponding slots 1242.
FIGS. 5-8 illustrate an alternate embodiment of the convertible game table 10 of the invention wherein the table top 12 is mounted upon a base 14 of a different configuration, having supports for the table top, in this example in the form of angled legs 147 which extend upward from a foundation, in this example in the form of longitudinal runners 148. The angled legs 147 meet at the midpoint of the ends of the table top 12 and receive the pins 133, 134 upon which the table top 12 rotates relative to the base 14 as described. A similar locking mechanism can be incorporated into the pins 133, 134 as described to prevent rotation of the table top. In each of the embodiments the pins 133, 134 can be completely removed from engagement with the table top 12 for purposes of packaging or storage. The table top 12 is preferably made of relatively light weight material such as molded plastic or structural foam, with the game playing surfaces 123 and 124 made of a harder material such as thick plastic sheet or wood. The same material or substrate can serve as the pool table playing surface 123 on one side (preferably covered with felt or other suitable fabric) and the ping-pong playing surface 124 on the other side. The base 14 can be made of any suitable material and formed as a single piece or assembled from parts.
In any one of the described embodiments, the table top 12 can be constructed as further detailed in FIG. 10, with the pool game playing surface 123 defined by a planar member 1230 which spans between the frame 122, and which is parallel to and spaced from the planar member 1240 which defines the ping-pong game playing surface 124. As noted, the material of the planar members 1230, 1240 can be any suitable rigid material which provides a sound game playing surface. The space 1234 between the planar members 1230 and 1240 can be occupied with any type of structural member or members as structural reinforcement, such as beams which span the length or width of the table top 12 between the frame 122, or structural foam which bonds to the planar members and the frame and maintains rigidity of the game playing surfaces. The space between the planar members 1230 and 1240 allows the pool ball pockets 127 and compartments 128 to be incorporated into the table top, as further shown in FIG. 9. In a construction wherein the space 1234 is filled or partially filled with any type of foam or other filler material, such material is regarded as a structural member.
Although the invention is described with reference to particular embodiments, the principles and concepts of the invention are of course executable in other forms not expressly described but nonetheless within the literal and equivalent scope of the claims to the invention.
