ABSTRACT:
BACKGROUND OF THE INVENTION
The present invention relates to a retaining device for decoration articles that are secured to the ends of the suspension rod of a Venetian blind. One end of each decoration article is provided with a cylindrical cavity of a proper depth. The cavity is defined in a tapered manner with its diameter gradually decreased inwardly to form an abutment surface for use in a suspension rod of a larger diameter which can be inserted into the decoration article and firmly held in place. At the bottom of the cavity is disposed an axially extended retaining post which has a plurality of radially protruded retaining plates. The front end of each retaining plate is provided with a smoothly arched edge and each retaining plate is gradually tapered with its height gradually increased inwardly. The retaining post is adapted for holding a suspension rod of smaller diameter which is inserted into the decoration article with the tapered retaining plates having smoothly arched edge of the retaining post in firm abutment with the inner surface of the suspension rod.
Generally, a suspension rod of a household Venetian blind mounted to a window or door is equipped with a decoration article at respective ends. There are two types of prior retaining device for such decoration articles.
Referring to
FIG. 1
, the first prior art includes a suspension rod
10
, a pair of decoration articles
20
and two screws
30
. The suspension rod
10
is a cylindrical hollow tube. Each decoration article
20
has one receiving cavity
21
of a proper depth engageable with each end of the suspension rod
10
. The receiving cavity
21
has a slightly larger diameter than that of each end of the cylindrical hollow suspension rod
10
. On the wall of the receiving cavity
21
is provided with a screw hole
22
. At the other end of the decoration article
20
is disposed a decorator
23
. In assembly, each decoration article
20
is engaged with one end of the suspension rod
10
with its receiving cavity
21
firmly and integrally secured in place by a screw
30
led through the screw hole
22
of each decoration article
20
.
Such a prior art has the following disadvantages:
1. The decoration articles
20
must be fixed in place to the suspension rod
10
by the screw
30
led through the screw hole
22
. It must be secured in place with a tool and the decoration articles can not be easily replaced.
2. The decoration articles are secured in place by screws
30
which can cause deformation on the suspension rod
10
as a result of locking forces.
3. The decoration articles
20
are only limitedly applied to one size of the suspension rod
10
.
Referring to
FIG. 2
, another prior art is made up of the suspension rod
10
, and a pair of decoration articles
40
each having a receiving cavity
41
. The receiving cavity
41
has a tapered form with its diameter inwardly reduced so as to form a conical abutting surface
42
. The decoration articles
40
having a decorator
43
at the other end are respectively locked to the ends of the suspension rod
10
with the articles
40
turned into tight engagement therewith, as a result of the tapered surface
42
abutting against the outer surface of the suspension rod
10
.
Such a second prior art has a disadvantage: the receiving cavity
41
of the decoration article
40
is only limitedly applied to suspension rods of one size; and many decoration articles
40
of different sizes must be provided for suspension rods
10
of various diameters.
SUMMARY OF THE INVENTION
Therefore, the primary object of the present invention is to provide a retaining device for a decoration article attached to ends of a suspension rod of a Venetian blind. It permits decoration articles easily and quickly secured to suspension rods of both large or small diameters whereby various decoration articles can be replaced with ease and speed.
