ABSTRACT:

FIELD OF THE INVENTION
The present invention relates to a seat device of a key ring, and especially to a seat device having an opening at a middle of a movable track so that the key hanging ring can be taken out easily. The user may take out any key hanging ring from the opening at a middle portion.
BACKGROUND OF THE INVENTION
Prior art key rings may can be used to locate a plurality of key hanging rings for being disposed with a plurality of keys. As desired, the key hanging rings can be taken out from or placed in the key ring so that the number of the key hanging ring can be adjusted as desired.
Referring to
FIG. 1
, the prior art key ring includes a seat
10
a,
key hanging rings
12
a
and a control device
12
a.
The seat
10
a
has an oblong shape and is connected to a key hanging ring
11
a.
Each key hanging ring
11
a
has an arm
13
a
and a head
14
a.
The key hanging ring
11
a
serves to hang keys. One end of the oblong seat
10
a
is installed with a movable track
15
a.
The head
14
a
is movably mounted to the movable track
15
a
of the seat
10
a.
One end of the movable track
15
a
is installed with a movable opening
16
a.
Through the opening
16
a,
the head
14
a
can be taken out from or placed in the movable track
15
a.
The movable opening
16
a
is formed by an enlarged end of the movable track
15
a
and is faced outwards. The control device
12
a
may be used to reduce the cross section of the movable opening
16
a
so as to be smaller than the cross section of the head
14
a.
Therefore, the movable opening
16
a
can be closed. Therefore, the head
14
a
is prevented from releasing from the movable opening
16
a.
When the control device
12
a
is pushed toward another direction, the movable opening
16
a
can be opened, so that the head
14
a
and the arm
13
a
may pass through the channel. As a result, the head
14
a
of the key hanging ring
11
a
may be taken out from or placed into the movable track
15
a.
Consequently, the user may adjust the number of the key hanging ring
11
a
as desired.
However, in the seat
10
a
of aforesaid prior art key rings, since the movable opening
16
a
is installed at one end of the movable track
15
a;
when a plurality of key hanging ring
11
a
are disposed on the seat
10
a
and the key hanging ring
11
a
to be taken out is placed at another end of the movable track
15
a,
farther from the movable opening
16
a,
all the key hanging rings
11
a
must be taken out for taking the key hanging ring
11
a
out at a farther end of the movable opening
16
a.
Therefore, the operation is time-consumed and inconvenient as the user is desired to taken out a key hanging ring
11
a.
SUMMARY OF THE INVENTION
Accordingly, the primary object of the present invention is to provide a seat device of a key ring, wherein the key ring of the present invention has a movable opening being installed in the movable track. When a plurality of key rings are positioned in the seat and one of the key rings is to be taken out, that is, the key ring to be taken out is placed at one end of the movable track, it is only necessary to push other key rings to another end of the movable track, then the key ring to be taken out can be taken out from the movable opening. Therefore, the key ring can be taken out easily, and the operation is time and labor saved. Any key ring can be taken out from the opening at the middle section.
To achieve the aforesaid object, the present invention provides a seat device of a key ring comprising a seat. The seat has an oblong shape, and an interior of the seat having a cruciform recess. One end of the sliding groove is formed with an opening and a movable opening can be formed through a control device. A movable track is formed interior the recess and near one end thereof for being connected to key rings. Thereby, the movable opening is installed at the middle portion of the movable track so that the key rings can be taken out easily and the user may take out any key ring from the opening at the middle portion.
The various objects and advantages of the present invention will be more readily understood from the following detailed description when read in conjunction with the appended drawing.
