STATEMENT REGARDING FEDERALLY SPONSORED RESEARCH OR DEVELOPMENT

FIELD OF THE INVENTION
The present invention relates generally to a rack for holding articles, and more particularly to a suction-type rack.
BACKGROUND OF THE INVENTION
As shown in
FIGS. 1 and 2
, a suction-type rack of the prior art comprises a suction cup
10
, a cover
20
, a tightening knob
30
, and an article-holding frame
40
. The suction cup
10
is provided in the outer side with a threaded rod
11
extending therefrom. The cover
20
is attached to the outer side of the suction cup
10
such that the threaded rod
11
of the suction cup
10
is extended out of the center hole of the cover
20
. The article-holding frame
40
is provided with a fastening end
41
and is fastened with the threaded rod
11
of the suction cup
10
by the tightening knob
30
in conjunction with a spring
12
which is fitted over the threaded rod
11
. The fastening end
41
is fitted over the threaded rod
11
and is fastened by the tightening knob
30
.
Such a prior art suction-type rack as described above is defective in design [in that] because the fastening end
41
of the article-holding frame
40
is not located securely on the threaded rod
11
, and because the article-holding frame
40
is susceptible to sideway movement by an external force, as illustrated in FIG.
2
.
BRIEF SUMMARY OF THE INVENTION
The primary objective of the present invention is to provide a suction-type rack which is free of the deficiency of the prior art suction-type rack described above.
In keeping with the principle of the present invention, the foregoing objective of the present invention is attained by the suction-type rack comprising a suction cup, a cover, a tightening knob, and an article-holding frame. The present invention is characterized by the cover which is provided in the outer side with a locating slot, and by the article-holding frame which is provided at the fastening portion thereof with a locating projection. The fastening portion of the article-holding frame is fastened with a threaded rod of the suction cup in conjunction with the tightening knob such that the locating projection of the fastening portion of the article-holding frame is retained in the locating slot of the cover, so as to locate securely the article-holding frame.
