Embodiment Construction

[0016] Turning now to the drawings, FIG. 1 shows a perspective view of a court standard 20 supporting one end portion of a net 18. Most generally, the court standard 20 for positioning a net 18 above a gymnasium floor 16 comprises: an embedded upright floor tube 22 having a top end portion which is nominally in alignment with the gymnasium floor 16; a contained tube 24 which is closely and slidably positioned within the floor tube 22; and a releasable lock means 26 to maintain the contained tube 24 at a selected height above the floor 16. In one embodiment, there are a plurality of contained tubes 24. Each contained tube 24 is closely and slidably positioned within a tube 24 or 22 therebelow.

[0017] A pneumatic supply line 70 supplies pneumatic power from a pneumatic supply to the embedded upright floor tube 22. Thus pneumatic power can be used to raise the contained tube or tubes 24 to the appropriate height. A pneumatic toggle switch 72 is incorporated into the pneumatic supply li...

Abstract

A collapsible court standard for positioning a net above a gymnasium floor includes an embedded upright floor tube with a top end which is level with the floor; one or more contained tubes slidably positioned within the floor tube; a releasable lock means and biased rocker latches to maintain the contained tubes at a selected height. Pneumatic power is supplied to the embedded upright floor to lift the contained tubes. The releasable lock means includes a split ring to maintain the net at a particular height. A shock absorbing pad cushions the contained tube upon retraction, and a movable floor cover is attached to the floor tube to provide access to the contained tubes. A winch and pulley are attached to a contained tube or innermost cylindrical member so that a net cable may be drawn over the pulley and tightened with the winch.

Description

PRIORITY DATA [0001] This application is a Continuation in Part of U.S. Patent application Ser. No. 10 / 714,094 filed on Nov. 17, 2003, entitled “Retractable Telescoping Court Standard” and is hereby incorporated by reference.FIELD OF THE INVENTION [0002] This invention relates to net support standards used in gymnasiums. More particularly this invention relates to net a support standard which telescopes down to a fraction of its extended height and then retracts below floor grade for storage. BACKGROUND OF THE INVENTION [0003] Most gymnasiums are used for many and all indoor sporting activities. A school gymnasium is typically continuously scheduled for different activities each hour. If volleyball, tennis, or badminton are played it is first necessary to access a storage room and carry the net standards from the storage room to a central portion of the gymnasium where they will be used. Before the conclusion of the scheduled time the standards must be removed and returned to the st...
