Abstract

The invention herein pertains to an antenna stand for radio broadcasts and particularly pertains to temporary antenna stands which are erected for on site broadcasts such as at shopping centers or the like remote from a permanent broadcast station. A collapsible antenna stand having mast sections is provided so an individual worker can erect, dismantle or vary the height of the antenna with relative ease and convenience. The antenna mast comprises a series of sections which are engaged and slidably raised through the bottom of a tripod having extendable legs.

Claims

1. A collapsible antenna stand for supporting an adjustable height antenna mast comprising:

a tripod, said tripod comprising three foldable legs, each of said legs having a lower, distal end for resting thereon, the lowermost points of each of said three distal ends of said foldable legs defining a spacial plane, a mast guide, said legs foldably joined to said mast guide, said mast guide defining a first mast bore, a brace assembly, said brace assembly comprising a mast support, said mast support defining a second mast bore, said brace assembly joined to said tripod, said second mast bore axially aligned with said first mast bore, a mast section, said mast section comprising a tubular member slidably positionable through said first and said second mast bores, said mast support spaced from said spacial plane such that the distance between said mast support and said spacial plane is greater than the length of said mast section, said brace assembly joined to said tripod whereby said mast section can be inserted into said second mast bore from beneath and upward into said first mast bore for engagement with a previously inserted mast section.

2. A collapsible antenna stand as claimed in claim 1 wherein said mast section comprises a tapered end.

3. A collapsible antenna stand as claimed in claim 1 wherein said mast section comprises a tubular member, said tubular member comprising a tapered end, said tapered end defining a locking tab slot, an end opposite said tapered end, said opposite end comprising a locking tab.

4. A collapsible antenna stand as claimed in claim 1 and including a brace guide, said guide attached at one end to one of said legs and the other end of said brace guide attached to said mast support to limit the movement of said mast support relative to said leg.

5. A collapsible antenna stand as claimed in claim 4 wherein said brace guide comprises a link chain.

6. A collapsible antenna stand as claimed in claim 1 wherein said brace assembly comprises means to lock said mast section therein.

7. A collapsible antenna stand as claimed in claim 6 wherein said locking means comprises a thumb screw.

8. A collapsible antenna stand as claimed in claim 1 and including a plurality of mast sections, each of said sections joined end to end, one to another.
