On the other hand, in the present specification, the term "voluntarily" means that the potential of the spring increases as the elastic guide means (spring) presses, and the first member or the second member moves in the direction of decreasing the potential. do.

(Example)

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

1 is an exploded perspective view of an example of a sliding structure according to the present invention. In FIG. 1, a first member 10 having a guard rail 11 formed on an opposite side, a buffer member 12 inserted into the guide rail 11 to facilitate sliding, and at the center A second member 20 having a protruding portion 22 and having a main body portion 21 symmetrically provided at an end portion of the protruding portion with the housing portion 23 interposed therebetween; One end 31 is rotatably fastened to the fixing pin 41 installed in the coupling hole 13 on the first member 10, and the other end 32 is disposed on the protrusion 22 of the second member 20. An elastic guide means 30 (spring) is shown, which is fastened to a fixing pin 42 installed in the engaging hole 24 and has a winding portion 33 between the ends 31, 32.

In FIG. 1, the first member 10 has a rectangular shape as an example. In addition, the accommodating portion 23 of the main body portion 21 of the second member 20 is formed as a groove, the inlet of the groove is formed with a bridge 23a, both sides 25 of the main body portion 21 ) Is a guide that moves along the guide rail 11 and the buffer member 12 of the first member 10.

Hereinafter, the coupling relationship for the above components will be described.

First, in the first member, the shock absorbing member 12 is inserted into the guide rail 11, and the fixing pins 41 are inserted into the two coupling holes 13, respectively.

Subsequently, one end 31 of an annular shape of the two springs 30 is fastened to the fixing pin 41.

Subsequently, both side surfaces 25 of the second member 20 are fitted to the guide rail 11 provided with the buffer member 12 of the first member 20.

Subsequently, the fixing pins 42 are inserted into the two coupling holes 24 on the protrusions 22, respectively.

Finally, the other end 32 of the annular shape of the spring 30 is fastened to the fixing pin 42.

Accordingly, the spring 30 is installed in the first member 10 and the second member 20 to interlock the first member and the second member.

FIG. 2 is a perspective view schematically illustrating a coupling relationship between the first member and the second member, in which the second member 20 is positioned on one side of the first member 10 on the first member 10 and in the lower side of the drawing. The spring 30 is fastened to the protrusions 22 of the first member 10 and the second member 2 via both ends 31 and 32. In addition, the two springs 30 are in a state in which they are disposed symmetrically with the protrusions 22 therebetween. In addition, the bridges 23a and the protrusions 11a of the guide rails 11 are positioned at various heights. In addition, the accommodating part 23 and the fixing pin 41 on the first part material are located parallel to each other.

According to this structure, as there is no need for another space for the spring 30 between the first member and the second member (formerly a space for the spring is formed between the first member and the second member), unnecessary It is to provide a sliding structure to prevent the increase in thickness (that is, the structure according to the present invention, since only the thickness of the first member and the second member plus the thickness, it becomes a slim structure).

On the other hand, by removing the protruding end 11a of the bridge 23a and the guide rail 11, the structure can be further slimmed down.

3 is a view showing the positional relationship of the members according to each step of moving the second member on the first member.

In the initial state of FIG. 3A, the second member 20 is positioned below the first member 10. In this case, the spring 30 is in a state where the potential is zero and is coupled to the fixing pin 41 of the first member and the fixing pin 42 of the second member.

Subsequently, in the state (a) of FIG. 3, when a predetermined force is applied to the second member in the upward direction or a predetermined force is applied to the first member in the downward direction, as in the state of FIG. The dog spring 30 is bent to increase the potential of the spring. Then, the second member 20 is moved from the A position to the B position. At this time, both ends 31 and 32 of the spring 30 rotate through the fixing pins 41 and 42. On the other hand, since the projections 22 are supported on both sides by the two springs 30, when the second member moves on the first member, biasing to one side does not occur.

3 (c) shows a state in which the potential of the spring is further increased as the spring 30 continues to be bent from the state of FIG. 3 (b), and the second member 20 moves from the B position to the C position. Will move.

Next, the state (d) of FIG. 3 is a state in which the second member spontaneously moves from the state (c) of FIG. That is, from the state (c) of FIG. 3, the spring 30 moves in the direction of decreasing potential, thereby raising the second member spontaneously from the C position to the D position.

Next, in FIG. 3E, the second member 20 voluntarily moves to the E position.

The structure of the present invention has been described above in detail with reference to the drawings. On the other hand, the structure according to the present invention as described above can be applied to various devices.

In particular, the present invention can be applied to a multimedia device such as a mobile phone. For example, as shown in FIG. 4, the second member 20 includes a main body 51 of a mobile phone including a control unit and a key input unit. The display unit 52 or the cursor key 53 may be configured at 10.

On the other hand, the reverse configuration is possible, it is also possible to configure a display unit or a cursor key on the second member, and to configure an input unit on the first member.
In addition, the display screen of the display unit 52 may be changed as the second member 20 moves on the first member 10.

As described above, according to the present invention, since there is no need for another space for the spring between the first member and the second member, there is no need for a space for the spring formed in the first and second members. Therefore, there is an effect that the thickness of the sliding structure is thin. In addition, there is an effect that the spring is accommodated in the side of the protrusion of the second member. In addition, by providing the structure according to the present invention to a multimedia device such as a mobile phone, there is an effect that the thickness of the multimedia device is reduced.
