Abstract
A compact disk receiving device includes a base and a cover pivotally connected to the base. Two recesses are defined in a top surface of the base and a protrusion is connected to an inside of each of the two recesses. Each the protrusion has an extension portion extending therefrom and a gap is defined between the protrusion and the extension portion so that the extension portion is able to be pushed to narrow the gap. Each extension portion has a ridge extending from an outside thereof so that the two ridges are engaged with an inner periphery of a central hole of a compact disk. When pushing the two protrusions toward with each other, a distance between the two ridges is shortened to allow the two protrusions to be inserted in the central hole of a compact disk.
Description




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.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT




Referring to

FIGS. 2

to


4


, the compact disk receiving device in accordance with the present invention comprises a base


20


having two recesses


34


defined in a top surface thereof and a flange


200


extends from a periphery of the base


20


. An engaging aperture


22


is defined through the flange


200


. A cover


201


is pivotally connected to the base


20


. A protrusion


31


is connected to an inside of each of the two recesses


34


and the protrusions


31


extend over the top surface of the base


20


. Each the protrusion


31


has an extension portion


32


extending therefrom and a gap


33


is defined between the protrusion


31


and the extension portion


32


so that the extension portion


32


is flexible when being pushing to narrow the gap


33


. Each extension portion


32


has a ridge


321


extending from an outside thereof A distance between the two ridges


321


is slightly longer than an inner periphery defining a central hole


41


of a compact disk


40


.




A notch


23


is defined in an underside of the cover


201


and the notch


23


is sized to receive the two protrusions


31


. A locking member


21


extends from the cover


20


and is able to be disengagably engaged with the engaging aperture


22


to receive the compact disk


40


in the receiving device.




Referring to

FIG. 4

, when putting the compact disk


40


in the compact disk receiving device, the two protrusions


31


are engaged with the inner periphery of the central hole


41


of the compact disk


40


, and then pushing the compact disk


40


downward to let the inner periphery of the central hole


41


push the two ridges


321


and then force the two extension portions


32


toward with each other till the inner periphery defining the central hole


41


of the compact disk


40


passes over the two ridges


321


as shown in FIG.


5


. By this way, the compact disk


40


is positioned.




As shown in

FIG. 6

, when taking the compact disk


40


from the two protrusions


31


, two fingers of the user push the two extension portions


32


toward with each other to shorten the distance between the two ridges


321


so that the two ridges


321


are disengaged from the central hole


41


of the compact disk


40


. There are only two protrusions


31


to be pushed when taking the compact disk


40


from the device so that the shortcomings happened on the conventional compact disk receiving device can be overcome.




While we have shown and described various embodiments in accordance with the present invention, it should be clear to those skilled in the art that further embodiments may be made without departing from the scope and spirit of the present invention.
