Pool table

Abstract

A pool table has a removable dining surface and a gravity-based ball-return system located transversely between end legs of the pool table. Balls that have been pocketed during a game on the table's playing bed are commonly collected in one of inclined two gullies that connect together multiple pockets. The gullies are peripheral to the table and directly beneath pockets that are, preferably, either side of a central longitudinal axis of the table. The ball return system includes a stacked arrangement of runners that receive a pocketed ball from a cascading drop at the end of each gully. Once into the stack, a ball separation device identifies and selectively separates a cue ball from object balls, with the cue ball directed downwards towards a free-return box while object balls are directed along a different downward path. Object balls are then retained behind a ball retainer and release mechanism which, when in a release position, causes delivery of all object balls to a ball picking slot at an end of the pool table common with the free-return box. Pool table depth is therefore minimized while space under the table's bed is maximized to accommodate seating.

DETAILED DESCRIPTION OF A PREFERRED EMBODIMENT

(8) FIG. 1 is a representation of a prior art pay-per-game cabinet pool dining table 10 shown to include a portion of a lift-off tabletop 12, including a connecting dowel pin 13 and receptive dowel cavities 15 into which locate corresponding dowel pins on complementary and abutting tabletop portions (not shown). Two or three tabletop portions assemble to produce a uniform table top. Locking wooden keys 17, in the form of wooden blocks, extend from the underside of the tabletop and permit a relatively secure locking of the tabletop portions 12 against side aprons 18-20 of the pool table.

(9) Conventionally, as is well-known, the pool table 10 includes a flat mechanically-stable bed 14 (typically of slate or the like) covered by a baize 16. Side aprons 18-20 define an upstanding cushion for the pool table 10, with these side aprons 18-20 and bed 14 secured to and supported by a cabinet 22. The pool table is conventionally rectangular in shape with a corner pocket 24 at each corner thereof and further side pockets 26 positioned midway along each of the major sides of the pool dining table 10.

(10) The cabinet 22 includes the ball return system that is described later in relation to FIG. 2. In this respect, the cabinet shows a ball picking slot 32 at a first end of the pool table 10, and a ball reservoir 34 in which is retained (by way of example) two pool balls 36. A payment device 38, such as a coin-operated release slot or electronic card payment device, is associated with cabinet and is operable to receive payment for pay-per-game operation, as is readily understood. Typically, the cabinet is itself supported by corner legs 28 each having adjustable-levelling feet 30.

(11) Turning to FIG. 2, there is shown a representation of an internal ball return mechanism and bed-support within the pay-per-game cabinet pool dining table of FIG. 1. FIG. 2 is a partial view showing about half of an entire pool table. The bed 14 is not present in FIG. 2, which bed would otherwise rest on upper surfaces 50 of lateral and longitudinal intersecting cross-members 52, 54 and/or ledges 56 that are fixedly secured into sides of the cabinet 22. For the sake of simplicity, only some of these cross-members and ledges are shown.

(12) What is noticeable in FIG. 2 is that a closed end gully 60typically formed in a plastics material and having a generally U-shaped cross-sectionis located beneath each pocket. Each gully is dimensioned to allow a pool ball to be channel from the entrance of the pocket and is inclined towards a lip that permits a ball, under gravity, to be rolled towards and then cascaded into a central collection box 64 defined between intersecting cross-members 52, 54. The gullies will generally extend through the cross-members to ensure that balls are always channeled into the central collection box 64.

(13) A floor of the central collection box 64 is inclined towards an edge 66 that defines a drop into a lateral ball distribution runner 68 that is relatively lower, i.e. beneath a floor level, of the central collection box 64. The lateral ball distribution runner 68 is therefore another channel at a lower level within the cabinet, with this ball distribution runner generally splitting the central collection box 64 into two inclined sections having respective surfaces that both feed a ball into this ball distribution runner 68.

(14) The distribution runner 68 is arranged to move pocketed balls towards a ball separation device 70 (such as a dimensioned hole or a gate) that functions to separate the cue ball from colored balls, with the ball separation device 70 again on an incline and configured to send the cue ball in the direction (Arrow A) of a free-return box (at the end of the table not shown) and to send colored (i.e. object) balls 36 to the ball reservoir 34 along an alternative path (Arrow B).

(15) FIG. 3 is a perspective view of a pool table 100 according to a preferred embodiment of the present invention. A description of the playing surface, e.g. side aprons, cushions, pocket locations and general construction resembles the prior art so will not be discussed in detail. However, as is shown in FIG. 3, the table 100 includes a baize covered bed 14, 16, top and side cushions 104 located along the periphery of the playing surface of the bed and positioned between pockets 106-108 cut into the bed 14. Conventionally, the cushions have angled end edges that define jaws 109 to each pocket. In contrast with the prior art, the table of FIG. 3 includes an end ball return mechanism that, preferably, includes a ball separation device hidden behind end/front fascia board 111. The ball separation device returns the cue-ball to a free-return box 113, whereas colored balls are accessed (eventually, subject to payment (if any) in a coin acceptor or bank card reader 115) from a ball picking slot 117.

(16) However, as shown in FIGS. 3 to 6, a novel ball collection layer and gravity-drop ball separation, collection and dispensing sub-system mean that a relatively shallow table (with an approximate depth of between about 12 cm to 18 cm (4.7 in to 7.1 in)) can be realized by the present invention and, furthermore, such as gravity-based system can also include an effective ball return feature to one end of the pool table, with edge-located inclined feed gullies (in a layer beneath the table's bed) connecting together multiple pockets to delivery balls along a path along a side edge of the table to the ball separation, collection and dispensing sub-system. The system of the present invention therefore allows for a less bulky pool dining table solution that can support pay-per-game play. In the preferred embodiment, there is no central collection box for balls. Rather, the gullies that interlink/interconnect pockets along principal (longest) sides of the pool dining table 100 function to run any pocketed ball along but beneath side edges of the table (relative to a central axis 107). The length of each gully allows a ball to acquire a reasonable amount of speed and momentum (so not to stall within the gully) following its drop into, for example, one of the middle pockets.

(17) Turning to FIG. 4, there is shown an exploded view of a preferred ball collection layer 102 of the pool table of FIG. 3. This layer 102 sits immediately below the bed of the pool table 100 and may be the layer on which the bed is directly supported (or at least mechanically coupled).

(18) Assuming, for the sake of explanation, that the pool dining table is conventionally shaped as a rectangle (rather than another regular polygon having at least six sides and an even number of sides), the ball collection layer 102 includes four periphery aprons 104, 106, 108, and 110. A first parallel pair of these aprons define a baulk (or kitchen) end at the bottom end 104 of the table and a top end 106 of the table. Two parallel side aprons 108-110, either side of a major longitudinal axis/centerline 107 of the table, define sides of the pool table and connect the bottom end 104 and top end 106 together. Inside of each side apron is an inclined gully 112 that includes a downward slope at an angle of between about one and five degrees sloping from the bottom end of the table and the top end of the table. An outer side 114 of each gully 112 is defined by an inner surface of each respective side apron 108-110. An inner surface of each gully 112 is defined by an upright support board 116 that runs from the top end to the bottom end and which upright support board 116 has an upper surface 118 on which the bed (not shown) may rests. The gully is sized to allow pool balls to run therealong towards the ball separation, collection and dispensing sub-system 150 (described below and shown particularly in FIGS. 5 and 6) at one end (usually the end remote from the kitchen/baulk end of the table) of the table 100.

(19) Preferably, each gully 112 may also include an inclined ball deflector board 120 that slopes inwardly from an outer edge of the table 100 towards the major longitudinal axis/centerline 107. This inclined ball deflector board may define a channel 123 that narrows (as the ball descends towards the ball separation device) to a width that is approximately that of a single pool ball's diameter. Of course, the configuration of the ball deflector board 120 is a design option although its function is to direct balls effectively downwards into the channel and then into the ball separation device at a cascading exit 130 positioned at the lowest end of each gully. The cascading exit 130 feeds balls into the ball separation device typically through a drop or inclined surface that is relatively lower than each gully 112. The cascading exit 130 may be realized by a hole dimensioned to allow a ball to drop directly through the hole in onto a switchback runner that is an integral part of the ball separation, collection and dispensing sub-system 150.

(20) Preferably, each of the two gullies is mirror-symmetric in shape and edge position relative to the major longitudinal axis 107 of the pool table. The pool table's depth d (from an upper surface of the cushion to the bottom of the side apron) is typically in the range of about 14 cm to 18 cm (5.5 in to 7.1 in) for a standard English seven-foot (2.14 m) pool table, with a floor to bottom edge clearance (to the base of the apron) of about 56 cm to 63 cm (22 in to 25 in).

(21) The channel and cooperating slopes within the gully 112, including an optional lower base ledge deflector 124 joining the gully's sloping base to the upright support board 116, are designed to see a pocketed ball relayed downhill for processing and sorting in the ball separation device. Each gully may further include one or more and usually multiple liquid drain holes 122. These drain holes 122 may be formed in the ball deflector board 120 or in the gully itself and are present to permit any liquid that has been spilt down the pockets to be effectively drained away to keep each gully free from liquid and the balls freely moving therein. The optional drain holes 122 act to reduce the likelihood of pooling or residual stickiness that could otherwise be exacerbated from pooling and/or evaporation of a pooled (rather than a drained) spillage within the gully.

(22) Pockets (into which, in play, pool balls are sunk/pocketed) are cut into the bed at its corners and also at a central middle position along the bed's major longitudinal axis 107 are positioned substantially directly over the gullies 112. Once located over the gullies 112, the bed has a height separation above component elements (such as either the base of the gully or the ball deflector board 120) that is sufficiently sized with a clearance that allows for the unencumbered free-running of the balls 36 within the gully.

(23) More usually, the bed of the table will be supported on a steel framework that is sits on/is mechanically coupled to the legs (either directly or indirectly through other support structure of the table, e.g. the side aprons). The fixing of the bed to the table is well-known in the art and this fixing does not affect the concept of a single end ball-return system.

(24) The side aprons extend above the upper surfaces 118 of the support boards, thereby allowing for the pool table's cushions to be fixed internally thereto to define, in combination with the baize-covered bed 14, 16, the playing surface of the pool table 100. In the event that the pool 100 table of FIGS. 3 to 6 realizes a pool dining table, then the cushions and bed are covered by one or more table top portions (e.g. element 12 as shown in FIG. 1).

(25) FIG. 5 is an exploded view of a preferred gravity-drop ball separation, collection and dispensing sub-system 150 of the pool table of FIG. 3 (and FIG. 4). FIG. 6 is an end view of the gravity-drop ball separation, collection and dispensing sub-system 150 of FIG. 5, the end view showing relative inclinations with a vertical stacking of inclined and descending balls runs. These figures will be discussed commonly below.

(26) Preferably, the single-end ball separation, collection and dispensing sub-system 150 is located transversely/laterally between (or at least partially between or in close proximity to) end legs 28 of the pool table 100 along a shorter side of the pool table. Positioning the single end ball separation, collection and dispensing sub-system 150 at this point maximizes the space beneath the pool dining table 100 (e.g. to accommodate chair and seating) and provides access to the ball picking slot 117. Both the free-return box 113 and the ball picking slot 117 are at a common end of the pool table 100 of the preferred embodiment.

(27) FIG. 5 shows the front fascia board 111 having strategically positioned holes that provide access to both the free-return box 113 and the ball picking slot 117. A second rear fascia panel 160 seal the back of the ball separation, collection and dispensing sub-system 150. The front fascia board 111 includes the optional user payment interface with associated control electronics and mechanics (for ball release) hidden internallyand sandwiched betweenthe fascia board 111 and the second rear fascia panel 160. For the sake of clarity, wiring for the electronics 170 and the mechanical connection is not explicitly shown, but it represented schematically in the drawings. Power (for example) for the payment card reader 115 and other equipment (such as an electrically-controlled telescopic rod or a mechanical gate that is selectively operable to release colored balls retained in a ball reservoir 176 therebehind (hereinafter the ball retainer and release mechanism 174)) is supplied by a power supply 172. The power supply 172 may be a rechargeable battery or a mains-driven power supply.

(28) FIG. 6 shows the path of colored pool balls 36 and the cue ball 36 through a vertical stack of inclined and descending balls runs that double-back on themselves from one side of the end to the pool table to the other side. The stack's depth is marginally wider that the diameter of the pool balls used in the game. Once assembled with the front fascia board and the rear facial panel, the vertical stack of inclined and descending balls runs is securely enclosed with access to pocketed balls restricted to the free-return box 113 or the ball picking slot 117.

(29) When a ball, regardless of whether it is a colored ball 36 or a cue ball 36, is pocketed and channeled via the gully to the cascading exit, the ball initially drops on a first inclined ball run 180 that is angled towards the center of the ball separation, collection and dispensing sub-system 150. This first ball run delivers the ball to a common second downwardly inclined ball run 182 that is inclined towards one of the two sides (and in the direction of the table's corner leg 28). This second ball run includes a ball separator 184. The ball separator may simply be a succession of slots or holes of differing width or diameter, with these holes allowing a larger colored ball 36 to be separated from a smaller cue ball 36. If the balls are the same size, such as in the American version of pool, then the ball separator 184 may be another electronically controlled gate, trap door or the like that is controlled to separate a differentiated colored ball from the cue ball. Regardless, the ball separator 184 drops a filtered-out cue ball onto a third downwardly inclined ball run 186 that feeds into the free-return box 113. Of course, once separated, the third downwardly inclined ball run 186 may not be necessary since the geometry of the ball separation, collection and dispensing sub-system 150 may simply drop the cue ball directly into the free-return box 113. With respect to the now separated path for the colored balls, these are (for example) dropped through a wider selection hole or trap into the ball reservoir 176 preferably (or at least typically) realized by a fourth downwardly inclined ball run 190. At a lower end of this fourth downwardly inclined ball run 190 is the ball retainer and release mechanism 174 that selectively retains or releases the colored balls into a final drop and onto a fifth inclined ball run 192 that delivers the colored balls (subject to there being the ball retainer and release mechanism 174 or it being in its open position) to the ball picking slot 117. The ball retainer and release mechanism 174 in combination with the coin acceptor or bank card reader 115 regulates paid play and access to the colored balls 36.

(30) Unless specific arrangements are mutually exclusive with one another, the various embodiments described herein can be combined to enhance system functionality and/or to produce complementary functions in the pool table's configuration. Such combinations will be readily appreciated by the skilled addressee given the totality of the foregoing description. Likewise, aspects of the preferred embodiments may be implemented in standalone arrangements where more limited and thus specific component functionality is provided within each of the interconnectedand therefore interactingsystem components albeit that, in sum, they together support, realize and produce the described real-world effect(s). Indeed, it will be understood that unless features in the particular preferred embodiments are expressly identified as incompatible with one another or the surrounding context implies that they are mutually exclusive and not readily combinable in a complementary and/or supportive sense, the totality of this disclosure contemplates and envisions that specific features of those complementary embodiments can be selectively combined to provide one or more comprehensive, but slightly different, technical solutions.

(31) It with, therefore, be appreciated that the above description has been given by way of example only and that modification in detail may be made within the scope of the present invention. For example, the single end return mechanism can be employed in other pool table shapes, such as regular six- or eight-sided regular polygons. Also, while the ball return mechanism has been described in the context of a pool dining table, the ball return mechanism could be used independently to reduce the overall weight of pool tables, including pay-per-game commercial slate-bed pool tables, in general. Equally, the present invention is not limited to the game of pool but could also be applied to other table ball games, such as snooker.

(32) Furthermore, while a preferred embodiment has two symmetrical gullies that each interconnect multiple pockets and which run directly beneath those pockets at the edge of the table, it is possible for a single interconnecting edge gully to connect all pockets or the two edge gullies to not be mirror opposites in the major access 107 of the table. The compromise in a longer channel relates to the vertical drop achieved between the highest point of the gully's slope and the point at the cascading exit. With a shallower draft, ball speed and ball momentum are respectively slower and smaller, so delivery of the balls to the single end ball separation, collection and dispensing sub-system 150 is slowed if the depth of the table is not increased to accommodate a sufficient end-to-end slope (typically in the range of between about one to three degrees based on a table depth of about 14 cm (5.5 in)). Also, with a single gully (that snakes around the periphery of the table to connect all pockets through a narrow gully) or a non-four-sided rectangular table, the peripheral gully will include a corner which potentially slows ball progress towards the single end ball separation, collection and dispensing sub-system 150. While the corner may be rounded to minimize any slowing effect, it is clearly preferable for the gully to have a substantially straight downward run from its highest point to the cascading exit 130 thereof.

(33) While the preferred embodiment is described with four legs, this need is optional. A central leg is a design option. In this instance, the ball separation, collection and dispensing sub-system nevertheless remains at one end (or a minor edge relative to a longer major edge) of the table.
