Abstract
A stand for a vertical pole support for a tether ball type game includes a base which can contain ballast and a lid, through which the pole passes and a formation on its floor for receiving the end of the pole. The lid and base are attached by a two stage attachment arrangement. The first stage includes inter-engageable tongue and groove formations which are capable of attachment and detachment by application of finger pressure, and the second stage includes locking devices at points around the periphery of the base container for a positive lock of the lid to the base, so that the first stage cannot be broken other than by the use of excessive force having regard to the conventional use of the stand.
Claims11
A movable stand for supporting a pole, comprising:
- a base container that is adapted to hold ballast and that comprises an open top and a generally U-shaped socket on an interior floor of said base container for holding a bottom of a pole;
- a lid that is adapted to close said open top, said lid having a through-hole for a pole that is in registration with said socket when said lid is attached to said base container;
- and
- an attachment system for attaching said lid to said base container, said attachment system comprising,
- a primary attachment system comprising a tongue on a periphery of said base container and a complementary groove in a periphery of said lid, said tongue fitting into and being enveloped and held closely by said groove when said lid is attached to said base container, and
- a secondary attachment system comprising at least two locking devices that selectively lock adjoining peripheries of said base container and said lid to prevent separation of said tongue from said groove.
A movable stand for supporting a pole, comprising:
- a base container that is adapted to hold a ballast and that comprises an open top;
- a lid that is adapted to close said open top, said lid having a through-hole for a pole, an annular portion of a said lid directly adjacent to said through-hole being thicker than a remainder of said lid;
- an annular clamp that extends into said through-hole and locks a pole in said through-hole;
- and
- an attachment system for attaching said lid to said base container, said attachment system comprising,
- a primary attachment system comprising a tongue on a periphery of said base container and a complementary groove in a periphery of said lid, said tongue fitting into and being enveloped and closely held by said groove when said lid is attached to said base container, and
- a secondary attachment system comprising at least two locking devices that selectively lock adjoining peripheries of said base container and said lid to prevent separation of said tongue from said groove.
