ABSTRACT:

FIELD OF THE INVENTION
The present invention relates to a key ring structure, in which the movable opening on a disk can be opened or closed by a button axially moving along an axial direction of a disk.
BACKGROUND OF THE INVENTION
The prior art key ring structure serves to place a plurality of key ring bodies for hanging more keys. Furthermore, the key ring bodies can be taken out or placed in the ring body flexibly.
The U.S. Pat. No. 4,584,858 discloses a key ring structure (referring to FIGS.
1
and
2
). The key ring structure has a disk
10
, at least one ring body
20
and a sliding device
30
. The disk
10
is placed with a ring body
20
. Each ring body
20
has an arm
21
and a head
22
. The ring body
20
serves to hang keys
40
. The head
22
is slidable installed in a groove
11
of the disk
10
. The opening of the groove
11
faces to the circumference of the disk
10
. The groove
11
is installed with a movable opening
12
. The head
22
can be taken out from or placed in the groove
11
through this opening
12
. The movable opening
12
is formed by an enlarged cross section of the groove
11
facing outwards. The sliding device
30
serves to reduce the cross section of the movable opening
12
so as to be smaller than the cross section of the head
22
, and therefore, the movable opening
12
can be closed (see FIG.
1
). Therefore, the head
22
is prevented from separation with the movable opening
12
. The sliding device
30
and the groove
11
are formed with a cross section of a channel so as to be passed by the head
22
and the arm
21
. When the sliding device
30
moves downwards radially along the disk
10
, the movable opening
12
can be opened (see
FIG. 2
) so as to be formed with a cross section of a channel. Therefore, the head
22
of the ring body
20
can be taken out or placed into the groove
11
for increasing or decreasing the number of the rings
20
.
However, in the aforesaid prior art ring, the sliding device
30
is opened through a handle
31
for controlling. The handle
31
is a smaller post and the sliding device
30
resists against a restoring spring
32
for providing a restoring force for closing the sliding device
30
. Therefore, as the user pushes the handle
31
, the operation is inconvenient and needs a larger force, even the finger will feel ache and thus the operations of taking out a ring body
20
or placing into the ring body
20
are inconvenient.
SUMMARY OF THE INVENTION
Accordingly, the primary object of the present invention is to provide a key ring structure, in which the movable opening on the disk can be opened or closed easily and conveniently by a button. The finger will not feel ache. Furthermore, the button axially moves along the disk so as to have a large area for pressing the button body. The finger will not feel uneasy and thus passing of the ring body is convenient.
To achieve the object, the present invention provides a key ring structure comprising an assembled disk, a ring, and a button.
The assembled disk is formed by a lower piece and an upper piece. An annular groove is formed between the upper piece and the lower piece. The opening of the groove faces toward a circumference of the disk. The lower piece and upper piece are installed with a first recess and a second recess. The first recess and the second recess are installed with respect to one another and are installed at two sides of the groove so that the groove is formed with a movable opening; and the movable opening faces outwards.
The head of the ring body is slidably installed to the groove of the disk. The head is capable of being moved out or placed in the groove through the disk.
The button has a button body. The button body is installed in the disk. A restoring spring is disposed between the button body and the disk. The button is movable along the disk. One side of the button body extends outwards so as to be formed as s stopper. The stopper is movably matched with the recess for controlling opening and closing of the movable opening. Therefore, a key ring structure is formed.
The various objects and advantages of the present invention will be more readily understood from the following detailed description when reading in conjunction with the appended drawing.
