ABSTRACT:
FIELD OF THE INVENTION
The present invention relates generally to a support frame for holding an object, such as Christmas tree, flag pole, sheet music, clothespole, and more particularly to a collapsible support frame.
BACKGROUND OF THE INVENTION
As show in
FIGS. 1 and 2
, a collapsible support frame of the prior art comprises a cylindrical main body and four support legs. The cylindrical main body is formed of an inner tube
1
and an outer tube
1
′ into which the inner tube
1
is fitted. The inner tube
1
is provided in the tube wall with a threaded hole
11
, and in the outer wall of the top end thereof with a protruded portion
12
. The outer tube
1
′ is provided in the tube wall with a through hole
13
is corresponding in location to the threaded hole
11
of the inner tube
1
. The notch
14
is corresponding location and size to the protruded portion
12
of the inner tube
1
. The inner tube
1
is fitted into the outer tube
1
′ such that the protruded portion
12
of the inner tube
1
is stopped by the notch
14
of the outer tube
1
′ and that the inner tube
1
is held in the outer tube
1
′ securely by a fastening bolt
15
which is engaged with the threaded hole
11
of the inner tube
1
via the through hole
13
of the outer tube
1
′. In assembling the inner tube
1
and the outer tube
1
′, the threaded hole
11
and the through hole
13
must be aligned. In disassembling the inner tube
1
and the outer tube
1
′, the fastening bolt
15
must be first unfastened. In addition, the protruded portion
12
and the notch
14
undermine the esthetic effect of the collapsible support frame of the prior art.
SUMMARY OF THE INVENTION
The primary objective of the present invention is to provide a collapsible support frame comprising an inner tube, an outer tube, and a plurality of support legs. The inner tube is fitted into the outer tube. The folding and the unfolding of the support legs are easily carried out by turning the inner tube a predetermined angle.
The features and the advantages of the present invention will be more readily understood upon a thoughtful deliberation of the following detailed description of a preferred embodiment of the present invention with reference to the accompanying drawings.
