Portable net support assembly for racket and ball games

Abstract

 A portable net support assembly for racket and ball games comprises a pair of self-supporting posts (10,11) interconnected by a strut, which preferably is formed of several axially interconnecting tubes (19,24). A foot (25) depends from the strut to contact a playing court surface on which the posts rest to act as a fulcrum whereby the tension in a net (26) carried by the posts (10,11) is counteracted.

Description

[0001] This invention relates to a portable net support assembly for racket and ball games. It has particular but not exclusive application, to tennis nets, especialy for use in playing the lawn tennis based games of Short or Compact Tennis (Trade Marks).

[0002] The posts which support tennis and like racket and ball game nets are usually permanently anchored (eg. in concrete) to oppose the bending movements applied thereto by the nets when the latter are tensioned to the required height for play. In certain installations, the posts may be releasably received in sockets but the whole support net assembly is not portable. Attempts to provide a portable racket and ball game net support assembly have not been successful to date.

[0003] The present invention provides a portable net support assembly for a racket and ball game, said assembly including:
a pair of self-supporting posts for standing on a playing court surface and
strut means interconnecting the posts and spaced above the supporting court surface;
characterised in that foot means depend from the strut means intermediate said posts to contact the court surface so as to act as a fulcrum to oppose bending movements applied to the posts upon tensioning a net between said posts.

[0004] The invention also provides a portable net assembly for a racket and ball game comprising a portable net support assembly of the invention and a net supported by and extending between the posts thereof.

[0005] Usually, at least one of the posts will include winding means for tensioning a net between the posts.

[0006] Preferably, the posts have detachable feet and/or are tubular to enable them to be filled with ballast, eg. sand.

[0007] Suitably each post has a horizontal arm adjacent its lower end and is braced by an oblique member interconnecting the post upright and said arm. Usually, the horizontal arms will form part of or be connected to the strut means.

[0008] In order to facilitate storage and transport, the strut means preferably is collapsible and comprises two or more telescopically or otherwise axially connectable members, especially tubular members. In this case, the horizontal arms, if present can be integral with the terminal members of the collapsible strut means.

[0009] Preferably, net engaging means, for example hooks are provided at spaced intervals along the strut means to secure the net thereto. When the strut means is collapsible, it is especially preferred that net-­engaging means are provided on each of the strut members.

[0010] The following is a description, by way of example only and with reference to the accompanying drawings, of a presently preferred embodiment of the invention. In the drawings:-

FIG. 1 shows a net support assembly, as assembled, with a net shown in dashed lines; and

FIG. 2 is an exploded view of the components of said assembly.

[0011] The assembly comprises a pair of posts 10, 11, each having a tubular upright 12, a horizontal arm 13 and an oblique brace 14 interconnecting said upright and arm.

[0012] A winding mechanism 15 (with a rachet) is mounted on one post 10 and an anchor hook 16 is provided on the other post 11. Lower net cord hooks 17 are provided on the arms 13.

[0013] Each post has a detachable foot 18 of hollow box section closed by end caps 19 and a peg 20 received in frictional engagement in the lower ends of the post upright 12. The feet 18 may be filled with ballast, eg. sand, if so desired.

[0014] The arms 13 are joined by a strut formed of six tubular members 19-24 interconnected by suitable male/female friction couplings. As shown in FIG. 1 the tubular members are aligned with (and connected to) the arms 13 and are spaced above the court surface. A foot 25 is formed integrally with tubular section 21 and contacts the court surface.

[0015] When a net 26 is attached to the posts 10, 11 and the winding mechanism 15 is operated, the tension in a top cord 27 of the net 26 tends to pull the uprights 12 inwardly (and would do so if the posts were not restrained).

[0016] The pivotal movement of the posts 10, 11 about the feet 18 is opposed by gravitational movement as the posts seek to pivot upwardly about the foot 25, the tubular members being rigid under tension.

[0017] The support assembly and net become balanced in tension when the net is at the correct playing height. If further tension is applied to the net to raise it further, this will tend to overload the tubular sections and they will tend to bow in the horizontal direction, indicating that too much tension has been applied to the net.

[0018] As stated above, the tension in the net will tend to pull the posts upwardly and inwardly but as this movement must be about the foot 25 as a fulcrum, the weight of the posts 10, 11 being raised about a relatively long lever arm, will oppose this movement and the uprights will remain vertical. In this manner, heavy bases or feet for the posts are not required.

[0019] By varying the dimensions the support assemblies can be used for tennis, volley, or badminton or other racket and ball sports. One particularly suitable application is for the tennis-based game operating under the Trade Mark "COMPACT TENNIS", in which case the posts will be 80-100 cms high and spaced 6-8 m apart.

[0020] As the components can be made from eg. tubular steel, aluminium or plastics material and the components are easily coupled together, the support assembly can be compactly packed for transport and easily assembled on site (and disassembled and packed for further transport).

[0021] It will be appreciated that the invention is not restricted to the particular details described above with reference to the presently preferred embodiment and that numerous modifications and variations can be made without departing from the scope of the invention as defined in the following claims. For example, the winding mechanism 15 can be replaced by one located within the post 12 in the manner of a conventional tennis net support post. Further, hooks 17 can be, and preferably are, provided on each strut member 19-24.
