The hinge portion 112 is formed at a position beyond the center of one bottom surface portion of the eccentric pivot 110. The hinge portion 112 is a portion rotatably coupled to the rotation support portion 212 described above. The eccentric pivot 110 has a cam portion 120 formed along the periphery of the center. The cam portion 120 is formed along the wall surface of the groove formed in the eccentric pivot 110. The cam portion 120 is a portion in which the distance from the center of the eccentric rotation part 110 is increased when viewed while rotating along the clockwise or counterclockwise direction with respect to the center of the eccentric rotation part 110 (hereinafter, ' 'Increased portion') and a reduced portion (hereinafter, referred to as a 'reduced portion') are alternately arranged, and the first to third bent portions 121 at the boundary between the 'increased portion' and the 'reduced portion'. , 122 and 123 are formed at intervals, respectively. The first to third bent portions 121, 122, and 123 interact with the elastic support portion 190, which will be described later, so that the cover portion 230 is closed, opened in the first direction, and opened in the second direction. It is intended to be able to stay at a stopped position.

That is, the cam part 120 includes the first bending part 121 and the slide circular motion part 150 contacting the elastic support part 190 while the slide circular motion part 150 to which the cover part 230 is fixedly coupled is closed.

Of course, when the rotation direction of the eccentric rotation part 110 is changed, the role of the first and second parts is changed.

As shown in Fig. 14, one eccentric pivot 110 may be provided. However, as shown in Figs. 1 to 4, it is preferable that a pair be provided to the left and right, and have a circular shape.

The pair of eccentric pivot 110 has a ring gear 110b having a gear 125 formed along the outer circumferential surface of the cam member 110a on which the cam 120 is formed through the screw member 118. It is preferable to combine. Accordingly, the eccentric pivot 110 has a shape in which gears 125 are formed along a predetermined circumference. And protruding jaw 127 is formed along the outer circumferential surface of the cam member (110a), so that it is caught by the locking jaw 166 formed along the inner circumferential surface of the circular receiving portion 168 to be described later so as not to pass upward. To confine the cam member 110a between the slide circular motion 150 and the main body 210.

In this case, one side of the slide circular motion unit 150 to be described later is interposed between the ring gear 110b and the cam member 110a so that the slide circular motion unit 150 is not separated from the eccentric rotation unit 110. It is convenient to do.

The two eccentric pivots 110 are spaced apart from each other, and the pinion 128 is engaged between the two eccentric pivots 110. Accordingly, when the cover portion 230 is opened and closed, the two eccentric rotation parts 110 are rotated in the same direction in the clockwise or counterclockwise direction with respect to their centers.

Next, the slide circular motion 150 is coupled to the eccentric pivot 110 to allow relative rotation of the eccentric pivot 110. The slide circular motion 150 is a circular motion around the hinge portion 112 when the eccentric rotation 110 is eccentrically rotated around the hinge portion (112).

The slide circular motion unit 150 is provided with a slide member 160 having a circular receiving portion 168, and a mounting portion 182 for mounting the elastic support portion 190 to be described later on the slide member 160. It is provided with a thin plate member 180 coupled to one side of the.

The thin plate member 180 is provided with holes 185 for fixing to the slide member 160 through the through hole 184 and the screw member 164 on one side in addition to the mounting portion 182. The thin plate member 180 may be integrally formed with the slide member 160 in some cases.

The accommodating part 168 of the slide circular motion part 150 is to allow the eccentric rotation part 110 to be accommodated and rotated, and the locking jaw 166 is formed along the inner circumferential surface thereof. The locking jaw 166 is interposed between the projection shaft 127 of the cam member 110a and the edge of the ring gear 110b so that it cannot be detached from the eccentric pivot 110.

On the other hand, the elastic support 190 is mounted to the mounting portion 182 of the slide circular motion 150. The elastic support portion 190 elastically supports the facing portion of the cam portion 120. The facing portion is varied according to the relative rotation angle of the eccentric pivot 110 relative to the slide circular motion 150. The elastic support part 190 elastically supports the first bent part 121, the second bent part 122, and the third bent part 123 of the cam part 120 to slide the circular motion part 150 and the cover part. The 230 serves to be able to stably stop in the closed state, the open state in the first direction, and the open state in the second direction, respectively. In addition, when the contact portion of the elastic support portion 190 is moving away from the center of the eccentric rotation portion 110, when the eccentric rotation portion 110 is rotating, the elastic support portion 190 is an elastic force to the cam portion 120 of the corresponding portion It also serves to allow the eccentric pivot 110 to be rotated automatically or with a small external force by this elastic force.

5 is an exploded perspective view of the elastic support. As shown in FIG. 5, the elastic support part 190 includes a fixing part 192 fixed to the slide circular motion part 150. The spring receiving portion 194 is formed inside the fixing portion 192. The spring accommodation part 194 accommodates the springs 196. As the spring 196, a coil spring is suitable. The number of springs 196 is suitable about four. The moving part 198 is coupled to the spring accommodating part 194. The moving unit 198 is coupled to the spring receiving unit 194 so as to be movable back and forth, and is supported by the spring 196. The end of the moving part 198 is pointed to provide a stable support for the first to third bent parts (121, 122, 123). It is preferable that the movable part 198 also has an empty space formed therein so as to accommodate a part of the spring 196.

6 to 10 is a closed position, a position being opened in the first direction, an open position in the first direction, a position being opened in the second direction, and opened in the second direction of the slide circular motion retractable portable electronic device according to the present invention. It is a top view which shows the movement states of the eccentric rotation part, the slide circular motion part, and the elastic support part, respectively in a position.

Referring to FIG. 6, in which the cover part 230 is closed, the cover part 230 is in an overlapping state with the main body part 210 under the cover part 230. In this state, the elastic support portions 190 on both sides support the first bent portion 121 of the cam portion 120 facing each other. Accordingly, the eccentric pivot 110, the slide circular motion 150, and the cover 230 may be in a stable closed state.

When the force is applied to the cover part 230 to the left in the state of FIG. 6, the eccentric rotation part 110 rotates clockwise around the hinge part 112, and thus is coupled to the eccentric rotation part 110. The slide circular motion part 150 and the cover part 230 open in a first direction as shown in FIG. 8 through a state shown in FIG. 7 by performing a circular motion in a clockwise direction about the hinge part 112. In this process, the two eccentric rotating parts 110 are rotated clockwise relative to the slide circular motion part 150, and the pinion 128 is rotated counterclockwise.

As the bilateral eccentric pivot 110 is rotated clockwise from the state of FIG. 6 to the state of FIG. 7, the elastic support 190 is in contact with the 'reduced portion' of the cam 120 where the distance to the center is gradually reduced. Therefore, external force should be applied sufficiently.

7, since both sides of the eccentric pivot 110 rotate in a clockwise direction, the elastic support 190 is in contact with the 'increased portion' of the cam 120 having an increased distance to the center. Even if not applied, the eccentric pivot 110 is rotated by the elastic force of the elastic support 190, so that it may be in a completely open state in the first direction as shown in FIG.

In the state of FIG. 8, the elastic support part 190 supports the second bent part 122. Accordingly, the eccentric pivot 110, the slide circular motion 150, and the cover 230 may stably maintain the open state in the first direction.

In the state of FIG. 8, when the eccentric rotation unit 110 is further rotated in the clockwise direction, the cover unit 230 may be opened in the second direction in a form similar to that of FIG. 10.

On the other hand, if you want to open in the second direction immediately in the closed state as shown in Figure 6 when applying a force to the cover portion 230 to the right, the eccentric rotation part 110 is rotated counterclockwise around the hinge portion 112 The circular circular motion part 150 coupled to the eccentric rotation part 110 also has a circular motion counterclockwise around the hinge part 112, and as shown in FIG. Open in two directions. In this process, the two eccentric rotating parts 110 are rotated in a counterclockwise direction relative to the slide circular motion part 150, and the pinion 128 is rotated in a clockwise direction.

From the state of FIG. 6 to the state of FIG. 9, as the two eccentric pivots 110 rotate in the counterclockwise direction, the elastic support part 190 is the 'reduced portion' of the cam part 120, the distance from the center of which is gradually reduced. Because of the contact, the external force must be applied sufficiently.

Since the elastic support portion 190 is in contact with the 'increasing portion' of the cam portion 120, the distance from the center increases gradually as both sides of the eccentric rotation 110 is rotated counterclockwise from the moment beyond approximately FIG. In this case, even if no external force is applied, the eccentric rotation part 110 may be rotated by the elastic force of the elastic support part 190 to be completely open in the second direction as shown in FIG. 10.

In the state of FIG. 10, the elastic support part 190 supports the third bent part 123. Accordingly, the eccentric pivot 110, the slide circular motion 150, and the cover 230 may stably maintain the open state in the second direction. When the jaw portion 124 of the third bent portion 123 is formed low, the third bent portion 123 may go straight from the state of FIG. 10 to the state of FIG. 6.

11 is a perspective view illustrating a modification of FIG. 1. As shown in FIG. 11, two pinions 128 may be provided between the two ring gears 110b. The rest is as described with reference to FIGS. 1 to 10.

12 is a perspective view illustrating a modified example of the eccentric pivot and the slide circular motion, and FIG. 13 is a perspective view of the eccentric pivot and the slide circular motion of FIG. 12 and 13, in place of the ring gear and pinion of the previous embodiment by connecting the two eccentric pivot 110 with a link (174a) it can be configured a slide circular motion opening and closing device according to the present invention. Of course, the link 174a should be rotatably connected with each eccentric rotation unit 110. Hinge portions 112 are respectively provided at the bottom edges of the two eccentric turning parts 110. Accordingly, the slide circular motion portion 150 may not have a pinion mounting portion.

14 is an exploded perspective view showing a modified example of the slide circular motion open and close portable electronic device according to the present invention. As shown, in some cases, by using only one eccentric pivot 110, it is possible to configure the slide circular motion switch 100 according to the present invention. That is, one pivot support part 212 is installed in the main body part 210, and one eccentric pivot part 110 is pivotally installed through the hinge part 112, and is formed on the slide member 160. Only one circular accommodating portion 168 is also formed in the center portion, and only one mounting portion 182 formed in the thin plate member 180 is installed in the central portion, and the slide circular motion switch 100 according to the present invention and using the same The slide circular motion retractable portable electronic device 200 may be configured. In order to prevent the slide member 160 from being separated, the hinge member 112 protruding from the upper side of the slide member 160 to the lower portion of the slide member 160 in a state in which the cam member 110a is coupled to the circular receiving portion 168. What is necessary is just to install the rotation support part 121 so that rotation is possible. The rest is as described above.
