Definitions

  • This invention relates to apparatus for playing table tennis.
  • Table tennis is frequently played as a team competition with teams of 3 to 6 players. However in these competitions the game is only played as singles or doubles matches. This means that a whole team cannot play at the same time.
  • table tennis triples which preferably, but not exclusively, utilises a round table. Extensive rules have been developed for the game. A description of the game can be found in: G. Arndt (2007): “Table Tennis Triples - A New Team Sport". Trafford Publishing, Canada, ISBN 978-1-4251-2136-5 ; and G. Arndt (2007): “Triples in Table Tennis: A Promising New Team Competition Sport - Introduction and First Findings". Proc. 10th ITTF Sports Science Congress, Zagreb, Croatia: May 2007: pp 444-462 ..
  • Document JP-9164232 A discloses a table tennis net having an increasing height zone and an outer zone that extends beyond the table.
  • the present invention provides a table tennis net to divide a playing surface into two regions by extending across the table surface; said net including a first centre zone to extend a selected substantially constant net height across the centre part of the table; transition zones to each side of the centre zone to respectively extend outwardly toward the table edges and provide a region of increasing net height toward the table edges; and outer zones joined to each of the transition zones extending outwardly beyond the respective table edges and below the playing surface.
  • this invention provides an extension for a substantially conventional table tennis net which when positioned adjacent to the conventional net provides a transition zone extending from one side of the centre zone of substantially constant net height to extend outwardly toward the table edge and provide a region of increasing net height toward the table edge, said extension further including outer zone joined to the transition zone to extend outwardly beyond the table edge and below the playing surface.
  • the extension is adapted to be releasably anchored to the table at a single position.
  • said single position is at the outer edge of the table.
  • the transition zone provides a substantially linear increase in net height from the boundary of the centre region to the edge of the table tennis table.
  • each outer zone is substantially symmetrical about an axis extending along the table surface.
  • the outer zones preferably extend outwardly, and, in a preferred embodiment of the invention, the edge of the net defines an arcuate portion.
  • the arcuate portion is preferably a smooth curve of radius centre on the edge of the table.
  • the centre zone has a length of approximately one third of the table width and each of the transition zones extend across approximately one third of the table each.
  • One form of the invention is a round table and has a diameter of 3.14 m.
  • the centre zone has a length of 105 cm, each of the transition zones is also 105 cm.
  • the radius of the outer zones is 41 cm.
  • the height of the centre zone above the table is the conventional table tennis net height of 6 inches (15.25 cm), and the transition zones linearly increase the net height from 15.25 cm to 41 cm where the outer zone commences.
  • the centre zone comprises a net portion which is movable to adjust the height of the centre zone.
  • the centre zone comprises a lower net portion and an upper net portion which is arranged to overlap the lower net portion and is movable relative to the lower net portion to adjust the height of the centre zone.
  • the present invention relates to apparatus developed for the game of table tennis triples.
  • the three basic equipment elements of the triples game are the table, the centrepiece and the net assembly.
  • the height of the triples table tennis table is the same as the conventional table tennis table but it differs significantly in that it is preferably of a round configuration.
  • There are two preferred table sizes - the "practice table” with a diameter of 2.74 m and “the standard” (or competition) table of 3.14 m in diameter.
  • the practice size is appropriate for practice and club matches particularly in confined venues.
  • triples table tennis table may be constructed. Although a rigid one piece 3.14 m diameter table is technically possible, the construction of the triples table generally would make use of separable or rotatably interconnected components which, amongst other benefits, confer advantages of storage and transport.
  • the table is constructed in a two-leaf folding manner analogous to that commonly used for conventional tables, the table surface being divided into two halves, both of which are hingedly attached to table support structures.
  • Conventional table tennis table support structures can be used in the construction of this embodiment of the invention.
  • the triples table may be composed of modular sectors.
  • these embodiments confer greater flexibility, reduced propensity to warp or deform and increased compactness for handling and storage.
  • Figure 10 depicts one such embodiment, in which the table 100 is comprised of six free-standing 60° sectors 102.
  • Figure 11 illustrates another such embodiment in which six 60° sectors 112 comprise three rotatably interconnected pairs 114.
  • the folding mechanism in each pair may operate in a manner analogous to the embodiment described in the previous paragraph. It is obvious that the components of these and other embodiments of the modular sector table design may be interchangeably combined to form a whole table.
  • a further embodiment of the invention is a composite triples table incorporating a standard rectangular table and specialist extensions that together form the circular triples table.
  • Figure 2 depicts the dimensions of a conventional table tennis table 30 as superimposed upon the dimensions of the 3.14m diameter triples table 32, the length 2A and width B of the conventional table being 2.74m (9 feet) and 1.525m (5 feet) respectively.
  • the conventional table is completely encompassed by the triples table, with the outlying triples table portions consisting of four circular segments comprising 2 major side portions 34 and 2 minor end portions 36.
  • the composite triples table can be constructed from a standard rectangular table and a set of extensions corresponding in dimension to these outlying portions.
  • the extensions comprising the two major side portions 34 may typically consist of either two free-standing circular segments or two pairs of hinged, attachable or free standing half circular segments (hereinafter referred to as "quarter segments"). In their preferred embodiments, the circular segments are 2.74m long and the quarter segments are 1.37m long.
  • Figure 3 depicts a single free standing major side portion extension consisting of a circular segment-shaped playing surface 42 and integrated net extension 44, supported by a number of legs 46. Other free-standing table extensions may not necessarily have this integrated net extension.
  • the free-standing embodiments of the extensions may be placed against the existing rectangular table either without any direct connection to it, or preferably may be secured in place by a combination of docking clips, pins and dowels 48 to achieve firm attachment and exact alignment.
  • standalone quarter segments will provide more versatility and ability to conform with height variations of a standard table - in particular where the standard table is comprised of 2 halves which may have independent variations in height.
  • the quarter segment extensions may also be constructed with or without integrated net extensions.
  • FIG. 4 depicts a composite table where the major side portion extensions are composed of quarter sections 52 hingedly attached to the rectangular table along axis 54 and supported by collapsible support legs 56.
  • the hinges 58 are positioned so that they do not protrude upon the playing surface when the quarter segments are in use.
  • the hinged major side portion extensions of the preferred 3.14m diameter table will come to rest at an angle of substantially 70° to the floor as they are wider than the table is tall.
  • the quarter segments When in this position and sheathed in a protective cover, the quarter segments, advantageously, confer the benefit of clearly visible advertising space, which is of major significance in public events where sponsorship logos etc. need to be prominently displayed.
  • the table configuration Owing to the provision of the hinged major side portion extensions, the table configuration can quickly and easily be transformed from rectangular to round and vice versa.
  • the minor end portion extensions may also be free standing, or hingedly attached (59 in Figure 4 ) to the rectangular table.
  • the minor end portions are 1.525 m long.
  • detachable end portion extensions without independent legs may also be possible.
  • FIG. 5 demonstrates a first embodiment in this regard, wherein a conventional table 62 is deployed along with major side portion extensions 64 designed for the 3.14m table, but without the corresponding minor end portions 36.
  • Figure 6 depicts a second embodiment in this regard wherein the conventional table 72 is incorporated into an hexagonal shape by the addition of equilateral triangle-shaped major side portion extensions 74 (or pairs of smaller triangle-shaped extensions 76).
  • the extensions for this hexagonal shape may be constructed in any of the previously described fashions.
  • An advantage of employing straight-edged shapes such as the extensions 74 is that they are generally easier to manufacture than shapes with curved edges. It should be noted that the rules of the triples game are independent of the table shape.
  • FIG. 1 shows a round table fitted with a net according to this invention.
  • the triples net is arranged over the parting line between the two table halves, and such that the portion of its bottom edge which overlies the table is as close as possible to, or touching, the playing surface. It also has substantially the same height as the conventional net, but only over its central portion. Given the shape of the triples table, some players (the "wing court players”) will be significantly closer to the net than in standard table tennis. To counterbalance this advantage, it has been deemed necessary to raise the net height in the region adjacent to their area of play 2.
  • the net being composed of a central portion of conventional height 4 and two transitional side portions of linearly increasing height 6, each of which terminate in a substantially semicircular end portion 8 which extends outward and downward from the periphery of the playing surface 9.
  • the length of each of the sloping portions and of the central horizontal portion is the same (1.05m in the standard 3.14m table embodiment), each being substantially one-third of the overall table diameter (measured along the table surface).
  • the side portions increase to a final height of 41cm.
  • the net is composed of the same material used for conventional nets, though, in other preferred embodiments it may be composed of any material or combination of materials suitable for the purposes of forming a net.
  • FIG 1 a preferred embodiment of the triples net 1 is seen, attached to the table by means of net posts 3 placed at the periphery of the playing surface 9.
  • These peripheral net posts 3 may have upward 151 as well as downward 152 extensions as per Figure 14 , but should preferably only point downwards from the playing surface.
  • the latter can be accomplished by using a strong (e.g. metal) frame running right around the net periphery and covered by cloth, firmly supporting the tensioned net, as will be described later.
  • a strong (e.g. metal) frame running right around the net periphery and covered by cloth, firmly supporting the tensioned net, as will be described later.
  • self-supporting wire mesh net material may be used.
  • a tension cord 153 may be inserted along the top edge as in conventional nets, this cord being continued from the sloping parts 154 to the centre 157, where it is anchored at a point (preferably 1.54 cm) above the table, as shown in Figure 14 .
  • Figure 14 shows an embodiment of a net which is for a standard table but which is provided with a triangular net adaptor 159 which fits to the peripheral post 151/152 and extends inwardly therefrom to be clamped to the edge of the narrower practice table, thus enabling the net to be used therewith.
  • the net on the preferred embodiment of the triples table is much longer than that on the rectangular table, i.e. 3.14 m (without the substantially semicircular side portions) as against 1.83 m (including the 15.25 cm overhangs). It has been found in practice that the strength and quality of today's nets does in fact allow these relatively long distances to be bridged in one span with essentially no central sag, though that is also guaranteed by additionally providing a central support post 156 as shown in Figure 14 , which then also serves as anchor for the abovementioned top net cord 153.
  • the net be composed of two symmetrical halves, each constituting one end portion, one transitional portion and one half each of the central portion of the net (as seen in Figure 12 ).
  • these half-nets may feature peripheral net posts that either extend downward or else both upward and downward from the playing surface (and in the case of the latter, the aforementioned addition of a tension cord 153 is also possible).
  • both net halves may be necessary for both net halves to possess a central support post, such that when deployed, the support posts of both halves of the net are directly adjacent at the centre of the table, where there is sufficient space to accommodate and secure them.
  • both halves may be clipped to a pre-existing central post.
  • Appropriate recesses are preferably provided under the net to accommodate the existing net posts 47 and support clamp structure.
  • One possible embodiment that achieves the overlap with the standard net incorporates a horizontal bar 49a, passing through both posts 40 and 45, and supporting a cantilevered net portion 49b.
  • the overall triples net shape is therefore generated by the combination of the existing conventional and the two triples extension nets.
  • FIG. 8 and 9 Further embodiments of such net variants may feature the outlying portions of the triples net as attachable extensions, as seen in Figures 8 and 9 .
  • the attachable extension 140 shown in Figure 8 is an example of an extension in which the peripheral net post 40 comprises only a downward extension 152.
  • the attachable extension 140 comprises a strong (e.g. metal) frame 141 incorporating both an inside net post 45 and peripheral net post 40.
  • the frame 141 unlike that of the extension shown in Figure 3 , does not comprise the horizontal bar 49a, whereby the section of net material of the cantilevered net portion 49b is not bounded by a frame member along its horizontal edge (which edge is received adjacent the top edge of the central portion 4). That section of net material comprises a cutout which defines the recess 142 accommodating the existing net post 47 and support clamp structure 143.
  • the section of net material 149 covering the area to the outer side of the inside net post 45 is attached to post 45, in addition to being attached to the remainder of the frame 141, so as to be kept taut.
  • the net material (in all of the embodiments) may comprise standard netting or a suitable alternative such as cloth, wire mesh or thin plastic sheet.
  • the extension 140 comprises clamps 144A and 144B (but may instead comprise alternative suitable attachment means) provided at the ends of the posts 40 and 45, respectively, adjacent the playing surface 9 for attaching the extension 140 to outermost 146 and inner 147 edges, respectively, of the table segment, the inner edge being defined at the blind (outer) end of a slot 49c (similar to that shown in Figure 3 ) through the segment extending perpendicularly outwardly from the innermost edge of the segment, the slot 49c allowing for the recess to be formed.
  • No frame member extends between the clamps 144A and 144B (i.e. the frame 141 does not run right around the net periphery), the lower edge of the net material 149 between them being received closely adjacent or touching the playing surface 9. Because the clamps 144A, 144B engage opposed edges of the table segment, they cannot be deflected towards each other under the tension of the net material 149, whereby deflection of the frame 141 is prevented, thus eliminating the need for a frame member between the clamps.
  • the end portion 8' is triangular, rather than semicircular (though could alternatively be semicircular, i.e. conform to the broken lines shown in Figure 8 ).
  • the triangle is isosceles.
  • the attachable extension 140' shown in Figure 9 is another example of an extension in which the peripheral net post 40 comprises only a downward extension 152.
  • the attachable extension 140' similarly comprises a strong (e.g. metal) frame 141' incorporating both an inside net post 45 and peripheral net post 40.
  • the frame 141' is the same as that of the extension 140 shown in Figure 8 though comprises an end portion 8" which is instead isosceles trapezoidal and further comprises a frame member 141A interconnecting the ends of the posts 40 and 45 such that the frame 141' is continuous and closed around the area of net outward of post 45.
  • this extension 140' comprises only a single attachment clamp 144, provided at the upper end of the peripheral net post 40, and further comprises a panel 145 which is attached to the post 45 and the frame member 141A, over substantially their whole lengths, to define a triangular brace or gusset 148 therebetween, the gusset 148 defining part of the net surface.
  • the frame member 141A rests on the table surface 9, with the gusset 148 stiffening the extension 140' sufficiently to prevent it skewing or otherwise deforming, whereby it can stand upright on the table.
  • the extension 140' can thus be attached to the table at only a single point, namely the outer edge 146 of the table segment, increasing the speed and simplicity of its installation.
  • a section of the frame member 141 B defining the upper edge of the transitional side portion extends inwardly beyond the post 45, as it does in the extension 140, to be cantilevered therefrom so as to provide the requisite support for the cantilevered net portion.
  • a triangular portion of the panel 145 extends inward of the post 45 and is attached to the section of frame member 141B to define therewith the cantilevered net portion 49b'.
  • the panel 145 may be made of plastic, or an alternative suitably rigid material, and may have either or both of the post 45 and frame member 141A embedded therein.
  • end portion may be formed in a variety of shapes, including those shown in Figures 3 , 8 and 9 , regardless of whether it is incorporated into an attachable or integrated extension or provided integrally with the centre zone, though preferably it will be generally convergent, i.e. of progressively reducing vertical dimension, in an outward direction and, in particular, symmetrical about the plane of the table surface.
  • Advantages of the extensions 140 and 140' are that they comprise only straight edge sections and may thus be easier to manufacture.
  • the table-net interaction solution is to provide two completely self-contained, independent net units 80 supported off the floor, which are simply placed against the table edge 81 and slipped into place, with two "half-nets" protruding to the centre of the table.
  • These "standalone nets” can in fact be used on any of the three table designs - or any others, for that matter. Since they extend right to the floor they also have the beneficial effect of indicating the territorial "boundaries" between the two teams, i.e. acting as mini-barriers between the two opposing wing courts.
  • One variant consists of a half-net 80 supported on an independent stand 82, with the cantilevered net end joining up with that of its counterpart at the centre 83 to form the complete triples net. For exact locating the net ends may be clipped to a central post 156.
  • the unit consists of a main support post 84 through which net support rod 85 passes at point 86. This rod 85 supports the horizontal portion of the net 87, and in a preferred embodiment is embedded in a fold at the top of said portion of the net.
  • a suspension wire or cord 88a (which in a preferred embodiment is also embedded in the net) holds up the net at point 88b, then passes over the main support post 84 at point 88c and down to its anchor point 88d at the base.
  • a counterweight may be necessary there to counteract the weight of the cantilevered net.
  • an optional screen 89 may be fitted for safety and aesthetics, and to remind wingcourt players of their "action space boundaries".
  • the unit may be fitted with fixed feet, or with lockable wheels 79. This allows easy set up and is also particularly useful for "handicap” games. Also, the net support rod 85 may be adjusted lengthwise, so that, for example during practice or for special effects, the horizontal part of the net may be shortened or "eliminated".
  • An aspect not courved by the claims, includes a centrepiece 5 for a table tennis table.
  • the centrepiece 5 serves two functions. Firstly, to prevent balls coming to rest "irretrievably" at the centre of the table, and secondly to effect an angled rebound for balls landing within the central region - a new challenge for table tennis players. Whilst the centrepiece 5 is technically only needed for the preferred "standard” (3.14 m) table; its use in conjunction with the "practice” (2.74 m) table may nevertheless be desired in order to practise the unaccustomed and less predictable rebounds off the centrepiece 5. The same applies for the versions of the composite table depicted in Figures 5 and 6 .
  • a low-set conical body of preferred diameter 40 cm (hereinafter referred to as the centrepiece) is situated at substantially the centre of the 3.14 m table. It fits essentially under the net, and assures that balls roll outwardly toward the periphery of the table, should they come to rest on said centrepiece.
  • the surface of the centrepiece is part of the playing area and must therefore have the same bounce characteristics as the parent table.
  • the angle of inclination of the centrepiece is chosen such that it deflects the balls landing on it (or purposely played there) in a way which still enables them to be reasonably played/returned.
  • Trials with central conical body of varying heights have suggested a preferred conical body height of 31 mm as this best satisfies the dual objectives of ball retrieval and angled rebound.
  • the centrepiece may be attached permanently to the table surface, either as an integral part or in two halves, or may be constructed as a removable unit - particularly suitable for use in conjunction with the composite or modular sector table embodiments.
  • two halves of the centrepiece are simply placed against the existing conventional net and are aligned with each other by means, for instance, of dowel pins which readily fit through or under the existing net.
  • the centrepiece 130 is also composed of six 60° sectors 133-138.
  • a central cut-out may be formed by truncating four of the six sectors 133-136 leaving two gaps 132 in the centrepiece suitable for a support post incorporated into an embodiment of the net assembly designed to accompany said modular table designs.
  • net assembly 120 shown in Figure 12 , which comprises support post 156 .
  • This post can, for example, be used to anchor tension strings 153 extending from the sloping net portions at the centre for extra strength and stability.
  • the relatively large diameter of the centrepiece enables the space underneath it to be utilised beneficially, for example to house electronic equipment needed for sensor-assisted umpiring. This applies particularly to the modular sector table embodiment discussed above.
  • FIG. 15 is partial view of a net 160 consisting of a conventional table tennis net 161, outlying portions in the form of attachable extensions 162, and a height-adjustable tensioned cord 163 attached to the extensions 162 above the level of the top edge of the net 161 and extending between the extensions 162 to define the top edge of the central portion 165.
  • a curtain or skirt 166 hangs from the cord 163, the skirt 166 being formed from a sheet of material which is doubled over about the cord 163 to define a pair of flaps 167 which overlap opposite sides of the net 161, such that the skirt 166 and net 161 together form the central portion 165 of the net 160, with the net 161 defining a lower net portion and the skirt 166 defining an upper net portion.
  • the flaps 167 also overlap opposite sides of the cantilevered net portion 49b of each extension 162 and are arranged such that the configuration of the net 160, and in particular the spacing between the outer surfaces of the flaps 167 and the conventional net 161 is the same on each side of the net.
  • Each extension 162 comprises a peripheral net post having an upward extension 151 in which holes 164 are provided at predetermined heights to receive a respective end of the cord 163, the heights corresponding to desired heights of the central portion 165, which will preferably range between 15.25 cm and 22cm and include a height of 17.25 cm which is the height used in the aforementioned "Large Ball” adaptation, which is popular in Japan.
  • a releasable stopper 168 is provided at each end of the cord 163 and received against an outer side of the upward extension 151 to retain the cord 163 in the post.
  • the top edges of the flaps 167 will cross the upper edge of the cantilevered net portion 49b and must thus be separated, or at least separable, at their outer ends.
  • slits are provided in the top edge of the skirt 166 at its outer ends.
  • the flaps 167 may be reinforced at those ends so as not to fall away from the net portion 49b/cord 163 at those positions.
  • the reinforcement may comprise, for example, a thin strip of plastic, which may extend along the full length of the skirt 166 and thus double as the conventional visible strip which runs along the top edge of the central net.
  • the ends of the flaps 167 may be rendered releasably attachable to net material, or to each other through the net material, for example by means of hook and loop or snap-lock fasteners.
  • the height adjustability of the central portion may not only be a feature of the net as comprising an attachable extension, such as is described above, but also one in which the outlying zones are provided integrally with the centre zone.
