Claims
What is claimed is:
1. A supporting frame with adjustable connecting joint including
four spiral rods connecting with several supporting plates for
receiving or placing goods, and a taped joint being consisted of
two half pieces by use of engagement of convex on the one piece and
groove on the other piece, and the joint having screwed inner
surface to match with the surface of the spiral rod, while the
joint can be rotated and moved upward or downward alone the rod;
the supporting plate being provided with a taped aperture at its
four ends and when the taped joint being engaged within the taped
aperture, it cannot be rotated or moved anymore.
2. The supporting frame with adjustable connecting joint as claimed
in claim 1, wherein the joint can be rotated and adjusted the
position on the spiral rod while the space between the nearby two
plates is adjustable for receiving different size goods.
Description
BACKGROUND OF THE INVENTION
[0001] A conventional supporting frame includes four supporting
rods and several plates for receiving goods thereon. The supporting
frame has a rigid structure wherein each plate is firmly engaged
its four ends with the four rods. The space between two plates is
hard to be changed. Large goods cannot be placed therein. And it
will be waste when only small goods are placed in a large fixed
space.
[0002] Accordingly, the present invention provides a supporting
frame with adjustable connecting joints, which includes spiral rods
and taped joints to provide an easy connection and adjustment
effectively for overcoming the drawback of prior art.
BRIEF DESCRIPTION OF THE DRAWINGS
[0003] The following drawings indicate the structure of the
supporting frame with adjustable connecting joints, along with
improvement and features of the present invention.
[0004] FIG. 1 shows a perspective view of parts of a supporting
frame according to the present invention.
[0005] FIG. 2 shows a partly cross-sectional plan view of the
supporting frame according the present invention.
[0006] FIG. 3 shows a completed assembled plan view of the
supporting frame according the present invention.
DETAILED DESCRIPTION OF THE INVENTION
[0007] Please referring to FIG. 1 to 3, the present invention
relates to an improvement of a supporting frame, which includes
four spiral rods (2) connecting with several supporting plates (3)
for receiving or placing goods. The invention also provides a taped
joint (1) being consisted of two half pieces (11), (12) by use of
engagement of convex (111) on the first piece (11) and groove (121)
on the second piece (12). The joint (1) has screwed inner surface
(13) to match with the surface of the spiral rod (2). So the joint
(1) can be rotated and moved upward or downward alone the rod
(2).
[0008] The supporting plate (3) is provided with a taped aperture
(31) at its four ends. As the taped joint (1) is engaged within the
taped aperture (31), it cannot be rotated or moved anymore. The
connection therebetween is firm and secure and the supporting frame
is utilized effectively.
[0009] In use, the taped joint (3) can be adjusted at any desired
position on the spiral rod (2) and then be connected with the plate
(3). The space between any two plates (3) can be adjusted easily
for receiving relating large or small goods. Other than the
commercial use, it is a novel, practical and progressive structure
design that absolutely well worth your attention and the patent
grant. In actually application, an adjustable foot (4) can be
connected with bottom end of each spiral rod (2) and a projection
(21) is provided at lower end of each spiral rod (2) to prevent the
lowest plate moved away from the rod.
