Definitions
- the present invention relates to a slider type portable terminal. More particularly, the invention relates to a slider type portable terminal, in which the whole thickness of the terminal can be minimized when it is opened, thereby improving the user's wearing comfort and the structural stability of the terminal. [2]
- Portable terminals can be categorized into a bar-type, a flip type, a folder type and the like.
- a slider-type portable terminal has been developed, where a sub-body equipped with a display slidably operates on a main body having a keypad.
- Fig. 1 shows an example of conventional slider-type portable terminals.
- a sub-body 2 is configured to slidably open and close with respect to a main body 3 in the arrow direction.
- This slider type terminal 1 takes advantage of a folder type terminal. That is, the sub-body 2 shields the keypad of the main body 3 when closed, to thereby avoid mal- operations or accidental operations.
- the receiver is installed in the sub-body and the transmitter is installed in the main body so as to secure a sufficient distance between the receiver and transmitter.
- the display mounted on the sub-body 2 faces forwards all the times.
- a single display can be used to reduce the production cost and the users can view the display even when the sub-body 2 is closed.
- the sub-body 2 and main body 3 are designed to linearly move against each other when they are being opened and closed.
- the conventional slider-type terminal 1 maintains the combined thickness of the main body 3 and sub-body 2 all the time during operations. [10] Therefore, when it is opened, the conventional slider- type terminal 1 comes to have a larger thickness, as compared with other types of portable terminals, thereby degrading the user's wearing comfort. [H]
- the present invention has been made in order to solve at least part of the problems in the art. It is an object of the invention to provide a slider type portable terminal, in which the whole thickness of the terminal can be minimized when it is opened, thereby improving the user's wearing comfort and the structural stability of the terminal.
- a slide-down type portable terminal comprising a main body, and a sub-body capable of sliding on the main body. Either one of the main body and the sub body is provided with a first slider groove formed along the sliding direction. The first slider groove has a straight portion and a curved-down portion consecutively formed from the straight portion. The other one of the main body and the sub body is provided with a first slider protrusion slidably engaging the slide groove, such that the sub body drops down while slidably opening with respect to the main body, or vice versa.
- a first slider plate and a second slider plate are fixed to the sub- body, and a first lever and a second lever are rotatably installed in the main body.
- the first lever allows the first slider plate to slide while the sub-body is in the straight portion and rotates by down-movement of the first slider plate during the curved-down portion.
- the second lever allows the second slider plate to slide while the sub-body is in the straight portion and rotates by down-movement of the second slider plate during the curved-down portion.
- a second slider groove is formed in either one of the first slider plate and the first lever and in either one of the second slider plate and the second lever.
- a slider protrusion is formed in the other one of the first slider plate and the first lever and in the other one of the second slider plate and the second lever. The slider protrusion is engaged with the second slider groove.
- a resiliently protruding means is installed in at least one of the first and second levers, and the first slider plate or the second slider plate or both is formed with a groove with which the resiliently protruding means is engaged.
- the resiliently protruding means includes a slider cam horizontally moving and having a first bevel face, a lift cam having a second bevel face face-contacting with the first bevel face and vertically moving to be engaged with and released from the groove, and a compression spring for urging the slider cam towards the lift cam.
- a clutch member is installed in the main body.
- the clutch member generates a resistant force against rotation of the first or second lever or both at the initial state and at the later state generating a force urging the rotation.
- the combined thickness of the terminal can be maximally reduced to thereby improve user s wearing comfort and the structural stability of the terminal.
