Abstract

A detachable fastening device of a sliding module in a sliding-type portable terminal includes: a guide member having one or more guide rails; a sliding member movable within a predetermined distance on the guide member in a state in which the sliding member is restrained to face the guide rails; and one or more swing dampers rotatably mounted at an entrance area of the guide member, the swing dampers allowing the sliding member in an assembled state to be readily disassembled, or the sliding member in a disassembled state to be readily assembled depending on whether it is swung or not.

Claims

1. A detachable fastening device of a sliding module in a sliding-type portable terminal, comprising:

a guide member having one or more guide rails;

a sliding member movable within a predetermined distance on the guide member in a state in which the sliding member is restrained to face the guide rails; and

one or more swing dampers rotatably mounted at an entrance area of the guide member, the swing dampers allowing the sliding member in an assembled state to be readily assembled and disassembled from the guide member.

2. The detachable fastening device as claimed in claim 1, wherein the swing dampers are formed from a flexible material.

3. The detachable fastening device as claimed in claim 1, wherein each of the swing dampers comprises:

a rotation restraint portion coupled to the entrance area in a direction perpendicular to the sliding direction; and

a swing body extending integrally with the rotation restraint portion, wherein if the swing body is received in the entrance area, one end of the swing body is arranged to protrude to the guide rail, and if the swing body is swung from the entrance area, the one end of the swing body escapes from the guide rail to allow the sliding member to be removed.

4. The detachable fastening device as claimed in claim 3, wherein the entrance area corresponds to the corners of the guide member, the entrance having a receiving recess to accommodate the swing body.

5. The detachable fastening device as claimed in claim 3, wherein the entrance area further comprises an inclined protrusion for helping the swing action of the swing body.

6. The detachable fastening device as claimed in claim 1, wherein the swing dampers are symmetrically arranged on the entrance area.

7. The detachable fastening device as claimed in claim 3, wherein the swing body is comprises a curved shape.

10. The detachable fastening device as claimed in claim 1, wherein each of the swing dampers comprises:

a rotation restraint portion coupled to the entrance area in a direction perpendicular to the sliding direction; and

a swing body extending integrally with the rotation restraint portion, wherein if the swing body is received in the entrance area, an end of the swing body is arranged to protrude to the guide rail to maintain the assembled state, and if the swing body is leaves from the entrance area, the one end of the swing body escapes from the guide rail to allow the sliding member to be removed from the guide member.

11. The detachable fastening device as claimed in claim 10, wherein the entrance area further comprises an inclined protrusion for helping the swing action of the swing body.

8. A detachable fastening device of a sliding module in a sliding-type portable terminal, comprising:

a guide member having one or more guide rails;

a sliding member slidably mountable to the guide member; and

one or more swing dampers rotatably mounted at an entrance area of the guide member to provide the sliding member in an assembled state or disassembled state to or from the guide member.

9. The detachable fastening device as claimed in claim 8, wherein the swing dampers are formed from a flexible material.

12. The detachable fastening device as claimed in claim 8, wherein the swing dampers are symmetrically arranged on the entrance area.

13. The detachable fastening device as claimed in claim 8, wherein the swing body comprises a curved shape.

14. The detachable fastening device as claimed in claim 8, wherein the guide member is adoptively coupled to a first body of the portable terminal.

15. The detachable fastening device as claimed in claim 8, wherein the sliding member movable is adoptively coupled to a second body of the portable terminal.
