ABSTRACT:
FIELD OF THE INVENTION
The present invention relates to a receiving device, and more particularly, to a compact disk receiving device which has two protrusions on a base and a cover pivotally connected to the base. Each protrusion has a ridge so as to engage with an inner periphery of a central hole of a compact disk.
BACKGROUND OF THE INVENTION
A conventional compact disk receiving device generally includes a base
10
and a cover pivotally connected to a side of the base
10
. An engaging means
11
composed of twelve pieces of plates
12
extends from a top of the base
10
. Each plate
12
is in a form of Z-shape and is made of flexible material so that the twelve plates
12
are located as a circular ring and an outer diameter of the ring is slightly larger than an inner periphery defining a central hole of a compact disk. When positioning a compact disk to the base
10
, the user simply presses the compact disk downward to let the central hole of the compact disk engage with the engaging means
11
. The plates
12
are forced to move downward and inward to narrow the outer diameter of the circular ring composed of the plates
12
so that the plates
12
are engaged with the central hole of the compact disk. When releasing the compact disk, the plates
12
bounce back and engage the central hole. When separating the compact disk from the engaging means
11
, the user presses the plates
12
to narrow the circular ring to pick the compact disk. Nevertheless, some of the plates
12
may not be pressed by the user's finger so that these plates
12
still engage with the central hole of the compact disk. When removing the compact disk from the engaging means
11
, these plates
12
that are not pressed could be broken or the compact disk is not separated from the plates
12
.
The present invention intends to provide a compact disk receiving device that includes only two protrusions to engage with the central hole of a compact disk so as to eliminate the shortcomings of the conventional compact disk receiving device.
SUMMARY OF THE INVENTION
In accordance with one aspect of the present invention, there is provided a compact disk receiving device and comprising a base having two recesses defined in a top surface thereof and a cover is pivotally connected to the base. A protrusion is connected to an inside of each of the two recesses and each the protrusion has an extension portion extending therefrom. A gap is defined between the protrusion and the extension portion. Each extension portion has a ridge extending from an outside thereof.
The object of the present invention is to provide a compact disk receiving device which has only two protrusions to hold the compact disk in position.
These and further objects, features and advantages of the present invention will become more obvious from the following description when taken in connection with the accompanying drawings which show, for purposes of illustration only, several embodiments in accordance with the present invention.
