That is, the opening and closing guide hole 31 of the rear member 30 is formed to be connected to the second long hole 312 via the locking step 313 in the first long hole 311.

On the other hand, the intermediate member 10 is formed with a third long hole 12 in a portion facing the opening and closing guide hole 31 of the rear member (30). The third long hole 12 is formed to extend in a direction inclined with respect to the second direction (W). Referring to FIG. 3, the third long hole 12 includes an intermediate member 10 and a rear member along a direction in which the locking jaw 313 and the third long hole 12 cross each other (second direction W). When the force 30 is applied away from each other, the slide rod 51 is disposed to be inclined at an angle capable of pushing the slide rod 51 from the locking jaw 313 to the second long hole 312.

The elastic member 50 is disposed to face the intermediate member 10 with the rear member 30 therebetween. The elastic member 50 is composed of a plurality of springs 53 arranged in parallel with each other is provided to provide an elastic force in the direction that the length is shortened. The elastic member 50 has a slide rod 51 protruding in a direction perpendicular to the rear member 30. The slide rod 51 is formed in the column shape. One end 52 of the elastic member 50 is connected to the back of the rear member (30). The other end of the elastic member 50 is the intermediate member 10 in such a way that the slide rod 51 is fitted into the third long hole 12 of the intermediate member 10 via the opening and closing guide hole 31 of the rear member 30.

By such a configuration, the elastic member 50 provides the elastic force to move the intermediate member 10 and the rear member 30 in a direction close to each other along the second direction (W).

A roller hole 34 is formed in the rear member 30, and a support roller 42 is installed in the rear surface of the link member 40. A support wall 341 is formed in the roller hole 34 so that the link member 40 can support the support roller 42 of the link member 40 when the link member 40 rotates with respect to the rear member 30. The support wall 341 of the roller hole 34 is in contact with the support roller 42 along the movement path of the support roller 42 to stably support the movement of the support roller 42. In addition, the roller hole 34 also serves as a stopper for preventing the support roller 42 from being caught on its inner wall to rotate the link member 40 over a predetermined angle.

Hereinafter, the operation mechanism of the sliding device for a portable device of the present embodiment configured as described above will be described.

First, the sliding device for a portable device of this embodiment is in a closed state as shown in Figs. As shown in FIG. 4, when the elastic member 50 exerts a force in a direction close to each other with respect to the rear member 30 and the intermediate member 10, the slide rod 51 of the elastic member 50 opens and closes the guide. The front member 20 and the rear member 30 are closed without being moved by the locking jaw 313 of the hole 31. In addition, the slide rod 51 is caught by the locking step 313, the elastic member 50 is limited in its contraction.

In this state, when the user pushes the front member 20 upward and upward with respect to the rear member 30, the front member 20 slides upward with respect to the intermediate member 10 along the first direction (L). The intermediate member 10 slides to the right with respect to the rear member 30 along the second direction W, and the link member 40 rotates counterclockwise. At this time, since the slide rod 51 of the elastic member 50 fitted in the third long hole 12 also moves to the right with respect to the rear member 30 along the intermediate member 10, the elastic member 50 continues to increase. While providing a resilient force in the direction of its contraction. Due to the elastic force of the elastic member 50, the link member 40 receives the elastic force to rotate in the clockwise direction, the front member 20 is subjected to the elastic force to move downward relative to the intermediate member 10, the middle Member 10 is subjected to an elastic force to move to the left with respect to the rear member (30).

When the link member 40 continues to rotate in the counterclockwise direction and the link member 40 is in parallel with the second direction W as shown in FIGS. 5 to 7, the slide rod is inserted into the third long hole 12. The elastic member 50 on which the 51 is restrained has the longest length. At this time, the front member 20 and the intermediate member 10 is located on the rightmost side with respect to the rear member 30, the slide rod 51 is located on the far right of the first long hole 311.

In such a state, when the front member 20 is pushed upward with respect to the rear member 30, the direction of the elastic force received by the link member 40 and the front member 20 by the elastic member 50 is switched. The link member 40 receives an elastic force to rotate in a counterclockwise direction, and the front member 20 receives an elastic force to move upward with respect to the intermediate member 10.

As such, the direction of the elastic force received by the link member 40 and the front member 20 is naturally changed to the open device for the portable device of the present embodiment as shown in FIGS. 8 to 10. That is, the slide rod 51 which is caught in the third long hole 12 moves to the left along the second long hole 312 and is fixed while being caught by the locking jaw 313 again as shown in FIG. 10. As shown in FIG. 8, the front member 20 is positioned at the uppermost position with respect to the intermediate member 10, and as shown in FIG. 9, the intermediate member 10 returns to the same position as the closed state with respect to the rear member 30. . Thus, when the sliding device for portable devices of this embodiment is opened, the portable device in which the sliding device for portable devices of this embodiment is installed will be in the state as shown in FIG.

In this state, when the user applies force to move the front member 20 downward with respect to the rear member 30, the front member 20 moves downward with respect to the intermediate member 10 and the link member 40 is clockwise. Direction and the intermediate member 10 is in a state as shown in FIGS. 5 to 7 while moving to the right with respect to the rear member 30. When the user moves the front member 20 further downward with respect to the rear member 30 in this state, the direction of the elastic force acting on the link member 40 and the front member 20 by the elastic member 50 While this is switched, it is in a closed state as shown in FIGS. 2 to 4.

In fact, when operating the sliding device for a portable device of the present embodiment is operated to automatically switch to the closed state and the open state without stopping in the intermediate position as shown in Figs.

In the above, the operation mechanism when the sliding device for portable devices of this embodiment is applied to the general-type portable device which has only the closed state and the open state was demonstrated.

Next, as shown in FIG. 15, the function of the sliding device for portable devices of this embodiment which enables the short-opening state of a portable device is demonstrated.

In the closed state as shown in Figs. 2 to 4, the sliding device for a portable device of the present embodiment can be operated so as to be in a single-axis open state as shown in Figs. It is convenient to use the mobile phone or the portable device so as to be in a state as shown in FIG. 15 without being generally opened as shown in FIG. In particular, if only a few frequently used buttons 72 and 72 are arranged vertically on the right side of the second body 70 to use only the necessary functions of the portable device, the portable device does not need to be opened as a whole. When the portable device is opened as shown in FIG. 14, a plurality of buttons 71 and 72 can be used. On the other hand, since the length of the portable device becomes longer, it may be inconvenient to carry or use. However, when used in the state shown in FIG. 15, the size of the portable device is very convenient because some functions can be used by pressing the buttons 72 and 73 without any significant difference from the closed state. As shown in FIG. 15, a state in which only a part of the buttons 72 and 73 of the portable device are opened will be referred to as a “shortened open state” for convenience.

First, in the closed state illustrated in FIGS. 2 to 4, the locking jaw 313 of the opening and closing guide hole 31 in the state where the slide rod 51 of the elastic member 50 is fitted in the third long hole 12. Is hanging on. In this state, when the front member 20 is pushed downward to the left side with respect to the rear member 30 by applying a force to the front member 20, the intermediate member 10 and the rear member 30 to move in a direction close to each other do. As the inclined surfaces of the locking jaw 313 and the third long hole 12 cross each other, the slide rod 51 is pushed upward. The slide rod 51 moved upward from the catching jaw 313 allows the intermediate member 10 to slide further left with respect to the rear member 30 while naturally moving to the second long hole 312. Due to the elastic force of the elastic member 50, the intermediate member 10 is moved further to the left side with respect to the rear member (30). At this time, the front member 20 slides downward with respect to the intermediate member 10 along the first direction L, and then the link member 40 is clockwise at an angle greater than or equal to the first direction L. When it rotates, it moves upward with respect to the intermediate | middle member 10 along the 1st direction L again, and stops in the state shown in FIG.

12 and 13, the intermediate member 10 slides to the left with respect to the rear member 30 so that the slide rod 51 is caught by the left end of the second long hole 312 so that it no longer moves to the left. Then, it stops in the short axis open state as shown in FIG.

In this state, when the user pushes the front member 20 downward to the right side with respect to the rear member 30, the intermediate member 10 moves to the right with respect to the rear member 30, and the link member 40 is counterclockwise. Will rotate. The slide rod 51 moving to the right along the second long hole 312 is moved downward again due to the elastic force of the elastic member 50 and the inclined direction of the third long hole 12 to be caught by the locking jaw 313. In this manner, the sliding device for a portable device of the present embodiment returns from the single-axis open state to the closed state.

On the other hand, when the sliding device for a portable device of the present embodiment is switched to the closed state, the open state, and the short axis open state, the support roller 42 of the link member 40 supports the roller hole 34 of the rear member 30. Roll along the wall 341. At this time, the inner wall of the roller hole 34 serves as a stopper to prevent the link member 40 from rotating any further in the open state and the short-axis open state.

Generally, when the user slides the first body 60 of the portable device with respect to the second body 70, the user moves the thumb. However, when the user applies a force to the first body 60 by moving the thumb, the user may move the first body 60 in the first direction L or in the second direction W rather than moving the thumb. It is more convenient to apply the force in the direction inclined in one direction L or the second direction W. FIG. Therefore, the use of the sliding device for a portable device of the present embodiment has the advantage of providing a more convenient slide structure to the user ergonomically.

In addition, since the sliding device for a portable device of the present embodiment provides the user with three use environments of an open state, a closed state, and a short open state, there is an advantage in that the user can use the mobile device in various ways. .

As mentioned above, although preferred embodiment was described about this invention, this invention is not limited to the form demonstrated above and shown in the figure.

For example, a sliding device for a portable device that provides only a closed state and an open state can be configured using the structure as described above. In this case, the second long hole 312 and other structures are unnecessary.

In addition, the wire member 41 is formed in the link member 40 to facilitate the fixing of the wire, but the wire may be fixed by another structure without the wire groove 41. For example, the flexible printed circuit board FPC, which is folded once in the first direction L and folded once in the second direction W, is formed between the front member 20 and the rear member 30. Can be used. In this case, due to the folding structure of the flexible circuit board, both ends may naturally move in the first direction (L) and the second direction (W), so that the first body 60 and the second body 70 naturally without distortion of the flexible circuit board. ) Can be connected miraculously.
