In addition, an object of the present invention is to provide a multimedia device such as a mobile phone employing the sliding structure.

In order to achieve the above object, the present invention includes a first member 10, and a second member 20 which is relatively sliding relative to the first member 10, the first member 10 Has a movement path forming portion 11 defining a moving direction of the second member 20, and the second member 20 has a rail forming portion 21 moving along the movement path forming portion 11. The movement path forming portion 11 formed on the first member 10 includes upper and lower movement path forming portions 11a and 11b on which a channel-shaped movement path 11c is formed. The moving path forming part 11 is provided in parallel and spaced apart by maintaining a predetermined distance d by the connecting part 12, and the rail forming part 21 formed in the second member 20 moves in the channel shape. It is formed in the corresponding shape of the channel that can be inserted into the furnace (11c) to move, and consists of an upper rail forming portion 21a and a lower rail forming portion 21b, the upper and The lower rail forming portion 21 is provided in parallel and provides a sliding structure, which is spaced apart while maintaining a predetermined distance d 'by the connecting portion 22.

In addition, the present invention provides a multimedia device having the sliding structure.

(Example)

Hereinafter, the present invention will be described in detail with reference to the drawings.

1 is a view showing a sliding structure according to the present invention, in the movable member 30 consisting of a first member 10 and a second member 20 which is relatively sliding relative to the first member 10. , The proximity and separation operation between the first member and the second member is shown.

Here, the first member 10 includes a movement path forming portion 11 which is a horizontal plate on which a movement path defining a movement direction of the second member 20 is formed. In addition, the second member 20 includes a rail forming part 21 which is a horizontal plate on which a rail moving along the moving path forming part 11 is formed.

Meanwhile, the movement path forming unit 11 formed on the first member 10 includes an upper movement path forming unit 11a and a lower movement path forming unit 11b in which a channel-shaped movement path 11c is formed. The upper and lower moving path forming parts 11a and b are provided in parallel and are spaced apart by maintaining a predetermined distance d by the connection part 12.

In addition, the rail forming portion 21 formed on the second member 20 is formed in the corresponding shape of the channel cross-section that can be inserted into the movement path (11c) of the channel form, the upper rail forming portion (21a) and It consists of a lower rail forming portion (21b), the upper and lower rail forming portion 21 is provided in parallel and are spaced apart by maintaining a predetermined distance (d ') by the connecting portion (22). Accordingly, the first member and the second member have a substantially "⊂" shape facing each other.

As the rail forming part 21 moves along the moving path forming part 11, that is, as the rail moves along the moving path, the first member and the second member are spaced apart or close to each other.

In addition, one end of the lower movement path forming portion 11b of the first member 10 (an end not facing the second member) is capable of shaft rotation with an additional member (for example, a frame member described below). An annular portion 13 for coupling is formed, and an additional member (for example, a frame member) is formed at one end of the upper rail forming portion 21a of the second member 20 (an end not facing the first member). A ring portion 23 for axially rotatable coupling with) is formed.

Accordingly, the ring portions 13 and 23 are positioned in a diagonal direction with the parallel moving path and the rail forming portions 11 and 21 interposed therebetween. This is a structure for facilitating shaft rotation of the first member and the second member by biasing the center of gravity.

On the other hand, the other end of the first member 10 is provided with a guide connecting portion 24 to be movable across the upper movement path forming portion (11a) and the lower movement path forming portion (11b). That is, it is hypothesized so that the connection part 24 may move along the guide 11d formed in predetermined length in the part which opposes the upper and lower movement path forming parts 11a and 11b. Here, the amount of movement on the guide 11d of the connecting portion 24 is determined according to the length of the guide 11d. In addition, the length of the guide 11d is formed shorter than the length of the moving path (11c).

On the other hand, the guide rod 24a is formed to protrude in both directions in the guide connecting portion 24, and the guide rod 24a is used for inserting the guide rods formed in the connecting portions 12 and 22 of the first member and the second member. Is inserted into and passed through the openings 12a and 22a.

Therefore, the guide connecting portion 24 is a guide rod 24a protruding in both directions from opposing side surfaces, and guides formed at opposing portions of the movement path forming portion 11 at sides other than the opposing side surfaces. It becomes a single piece provided with both ends 24b which are rails which move along 11d. As an example, the guide 11d is formed of a flat protrusion, and both ends 2b are formed in a groove shape in which protrusions are accommodated.

On the other hand, in the present embodiment, three guide rods 24a are shown, but the number can be changed in various ways in connection with the rigidity of the sliding structure.

In addition, at the other end of the upper rail forming portion 21 of the second member 20 (an end facing the first member), an agent for preventing the rail forming portion 21 from escaping from the moving path 11c. One stopper member 25 is provided. For example, the first stopper member may be formed by processing the tip portion of the rail forming portion 21 to form a ring in the form of an arrowhead or a hook. Accordingly, the second stopper member 15, which is a blocking member that prevents the second stopper member 25 from being separated, may be provided at the end of the movement path 11c of the first member 10. In addition, in FIG. 1, the 1st and 2nd stopper member was shown large in order to make understanding easy.

Accordingly, the guide rod 24a is inserted into the openings 12a and 22a with both ends 24b of the guide connecting portion 24 inserted into the guide 11d, and then the first stopper member 25 is When the rail forming portions 21a and b formed at the front end are forcibly inserted into the movement path forming portions 11a and b in which the second stopper member 15 is formed, the movable of the first member and the second member is prevented from being separated. The member 30 is formed.

In addition, in FIG. 1, reference numeral 21c denotes a stepped portion or flange 21c different in height from the main portion of the rail forming portion 21. Therefore, it can be seen that the cross-sectional shape of the movement path forming part 11 may also be variously changed according to the shape of the rail forming part 21.

Here, (a) of FIG. 1 shows a state in which the first member and the second member are spaced apart, and FIG. 1 (b) shows a close state. In the spaced state of FIG. 24 is located at the other end of the 1st member which opposes a 2nd member adjacently on the guide 11d formed in the mutually opposing part of the upper and lower movement path formation parts 11a, 11b, and guide rod 24a. The tip of) is inserted into the opening in the vicinity of the openings 12a and 22a for insertion.
