Abstract
A support unit comprises a ground base unit made of a sturdy pipe having annular washers. The holes in the washers are aligned and adapted to receive a support pipe which extends above the ground base unit for supporting an object such as a mailbox. The object is rotatably attached to the support pipe with elastic elements which return the object to a predetermined orientation after displacement. Also, if the support pipe is damaged, it is easily replaced.
Claims6
A support comprising:
- a first hollow cylindrical element having a cylindrical axis and an inner cavity having a first cross-sectional dimension,
- two annular washers, each attached to said first cylindrical element and each having a central hole having a diameter smaller than said first cross-sectional dimension and aligned with an axis generally parallel with said cylindrical axis of said first cylindrical element,
- support means for supporting an object and adapted to be received in said central holes and thus held by said two annular washers,
- a locking collar adapted to be secured to said support means, for preventing relative motion in the direction of said cylindrical axis, beyond a predetermined point, between said support means and said first cylindrical element, and
- means for attaching an object to said support means.

A support comprising:
- a first cylindrical element,
- two annular washers, each attached to said first cylindrical element and each having a central hole aligned with an axis generally parallel with the axis of said cylindrical element,
- support means for supporting an object and adapted to be held by said two annular washers,
- a locking collar adapted to be secured to said support means, for preventing relative motion, past a predetermined point, between said support means and said first cylindrical element and,
- means for attaching an object to said support means;
- wherein said support means comprises a second cylindrical element having threads on one end, and said means for attaching an object to said support means comprises:
- a plate for supporting said object,
- a threaded cylindrical element, secured at one end to said plate, for mating with said threaded portion of said support means,
- means attached to said threaded element, for frictionally grasping said support means,
- elastic means connected between said threaded cylindrical element and said support means for returning said plate to a predetermined orientation with respect to said support pipe after rotational displacement of said plate.
