Abstract

Disclosed is a cover replacement assembly for a mobile communication terminal, wherein a replaceable cover is detachably secured to a frame coupled to the terminal. The cover and frame are formed with locking means that snap fit. Locking members formed on the cover engage a locking sill formed on the frame. Also, locking element that is inserted into an aperture in the frame can be manipulated in order to detach the cover from the frame and terminal.

Claims

1. A cover assembly for a mobile communication terminal, the assembly comprising:

a frame coupled to the terminal, wherein the frame comprises;

a locking sill; and

a locking aperture; and

a cover detachably secured to the folder frame, wherein the cover comprises;

a locking element to engage the locking aperture; and

at least one locking member to engage the locking sill.

2. The assembly of claim 1, wherein the at least one locking member engages the locking sill via snap fit.

3. The assembly of claim 1, wherein the at least one locking member is formed on a lateral edge of the cover and the locking sill is formed along on an inner surface of the frame.

4. The assembly of claim 3, wherein the at least one locking member and the locking sill each comprise a protruding groove so that the protruding groove of the locking member opposes the protruding groove of the locking sill, whereby the protruding grooves of the locking member and the locking sill tightly engage each other in a locking relationship.

5. The assembly of claim 1, wherein the locking element comprises a hook portion that is inserted into the locking aperture when the cover is detachably secured to the frame.

6. The assembly of claim 5, wherein the locking aperture comprises an external cross-sectional area to allow contact with the locking element so that the locking element disengages the aperture.

7. The assembly of claim 6, wherein the locking aperture and the locking element are formed on corresponding distal ends of the frame and the cover, respectively.

8. The assembly of claim 1, further comprising a polymer.

9. A folding type mobile communication terminal comprising:

a first folding member;

a second folding member rotatably coupled to the first folding member;

a cover detachably secured to the frame, wherein the cover comprises;

a locking element formed on an end of the cover; and

a plurality of locking members formed on opposing lateral edges of the cover; and

a frame coupled to each folding member, wherein the frame comprises;

a locking sill, which is formed on an inner surface of the frame, to engage the plurality of locking members; and

a locking aperture, which is formed on an end of the frame corresponding to the end of cover where the locking element is formed, to engage the locking element.

10. The terminal of claim 9, wherein

each locking member of the plurality of locking members comprise a protruding groove;

and

the locking sill comprises a protruding groove that opposes and tightly engages the protruding grooves of plurality of locking members in an locking relationship.

11. The terminal of claim 10, wherein the locking element comprises a hook portion that is inserted into the locking aperture when the cover is detachably secured to the frame.

12. The terminal of claim 11, wherein the locking aperture comprises an external cross-sectional area to allow contact with the locking element so that the locking element disengages the aperture.

13. The terminal of claim 9, wherein the frame and cover each comprise a polymer.

14. A cover assembly for a mobile communication terminal, the assembly comprising:

a frame coupled to the terminal; and

a cover detachably secured to the frame; and

a fastener for detachably securing the cover to the frame.

15. The assembly of claim 14, wherein the fastener comprises:

a locking element formed on a distal end of the cover; and

a plurality of locking members formed on opposing lateral edges of the cover;

a locking sill formed on an inner surface of the frame to engage the plurality of locking members in a snap fit configuration; and

a locking aperture formed on a corresponding distal end of the frame to engage the locking element.

16. A method of fastening a cover to a mobile communication terminal, the method comprising the steps of:

placing the cover on a frame coupled to the terminal so that a plurality of locking members formed on the cover is situated within an inner surface of the frame;

aligning a locking element formed on the cover with an aperture formed on the frame; and

pressing the cover and the frame together to snap fit the cover to the frame.

17. A method of detaching a cover to a mobile communication terminal, the method comprising the steps of:

pressing a locking element, which is formed on a distal end of the cover, through a locking aperture formed on a distal end of a frame coupled to the terminal;

lifting the distal end of the cover so as to completely disengage the locking element from the locking aperture;

lifting lateral edges of the cover;

pressing a plurality of locking members, which are formed on lateral edges of the cover, to disengage a locking sill formed on an inner surface of the frame; and

removing the cover from the frame.
