It is preferable that the stopper is a roller.

Preferably, the stop groove is formed at a position corresponding to the position of the stopper when the second hinge part is located at an intermediate portion of an area moved by the spring.

On the other hand, the sliding type mobile phone according to the present invention, preferably includes the slide assembly.

Hereinafter, with reference to the drawings will be described in detail. However, these drawings are for illustrative purposes only and the present invention is not limited thereto.

1 is a plan view and a cross-sectional view of a slide assembly corresponding to a standby state of a portable communication device according to an embodiment of the present invention. The lower figure is a top view, and the upper figure is sectional drawing of A-A. In the sectional view, the spring 50 is omitted.

Referring to Figure 1, the slit assembly according to the present invention, the first hinge part 10, the second hinge part 20, the roller 30, the tension spring 40, the spring 50 is configured to include .

The first hinge part 10 is connected to the LCD screen part (display part, upper part) of the conventional slide phone, and the second hinge part 20 is connected to the keypad part (lower part) of the slide phone.

In the figure, the second hinge part 20 connected to the lower part of the slide phone is shown to be located at the upper part.

Although the spring 50 is covered by the second hinge part 20, it is indicated by a solid line for convenience of understanding.

Sliding of the first hinge part 10 and the second hinge part 20 is made by a sliding POM 60 which is a lubrication part interposed therebetween.

It is the spring 50 that gives elasticity to the first hinge part 10 and the second hinge part 20. Reference numeral 14 is a connecting means with the spring 50 formed on the first hinge part 10, 26 is a connecting means with the spring 50 formed on the second hinge part 20.

The spring 50 may be of various types of torsion springs or the like cited in the prior art of the present invention.

The stop groove 12 is formed on the side surface of the first hinge part 10.

Guide rails 22 are formed in the second hinge part 20.

The stopper corresponding to the stop groove 12 is formed in the guide rail 22. The stopper is composed of a roller 30 and an accessory device 32 connected to the shaft of the roller 30 and fitted to the guide rail 22.

A ring 24 is formed at a predetermined position of the second hinge part 20, and the ring 24 and the accessory device 32 are connected by the tension spring 40 so that the roller 30 is in the center portion of the hinge. It is to be strengthened by.

When the roller 30 is located in the stop groove 12, an external force must be applied to the roller 30 to escape the stop groove 12.

When an external force is applied, the roller 30 may move to the upper or lower portion of the stop groove 12.

The spring 50 of FIG. 1 has the potential for pushing between the reference numeral 14 and the reference numeral 26. On the contrary, the spring 50 of Figs. 2 and 3 is at its maximum relaxed state. Since the first hinge part 10 and the second hinge part 20 of FIG. 1 have stronger coupling force by the roller 30 and the stop groove 12 than the repulsive force generated by the spring 50, a force is applied from the outside. If not, the state of FIG. 1 is maintained.

Accordingly, when the second hinge part 30 is pushed upward in the drawing, the roller 30 moves upward by the force accumulated in the spring 50 as long as the roller 30 leaves the stop groove 12.

In the drawing, when the second hinge part 30 is pushed downward, the spring 50 is compressed even when the roller 30 is out of the stop groove 12. The two hinge parts 30 move. The predetermined distance is up to the critical point formed by the spring 50. The critical point is a point at which the reference numeral 14 and the reference numeral 26 become horizontal.

As such, the roller 30 does not need to apply any more force to the top of the stop groove 12 upwards, and if the roller 30 exits to the bottom, additional force must be applied to the critical point, so as to form the stop groove 12 as shown in FIG. In the drawings, the upper portion may have a sharp inclination and the lower portion may be gently formed.

2 is a plan view and a cross-sectional view of a slide assembly corresponding to a first communication state of a portable communication device according to an embodiment of the present invention. The lower figure is a top view, and the upper figure is sectional drawing of B-B. In the sectional view, the spring 50 is omitted.

FIG. 2 is a final state in which a force is applied to move the second hinge part 20 downward in FIG. 1.

When the force is applied downwardly to the second hinge part 20 in FIG. 1, the roller 30 located in the stop groove 12 overcomes the force of the tension spring 40 and is separated from the stop groove 12. When the force is applied to overcome the force of the spring 50 and move downward, and applying a force to a predetermined threshold point (horizontal reference numerals 14 and 26 are horizontal), the compressive force accumulated in the spring 50 to the position of Figure 2 To move automatically.

FIG. 2 corresponds to a first communication state of the mobile communication device. Since the LCD screen portion of the slide mobile phone is connected to the first hinge part 10, and the keypad portion is connected to the second hinge part 20, the LCD screen is connected to the first hinge part 10. The addition corresponds to moving upwards, and corresponds to opening the mobile phone in the existing slide type mobile phone.

In the first communication state of FIG. 2, a telephone call, a text message, or the like may be performed using the keypad of the keypad unit.

3 is a plan view and a cross-sectional view of a slide assembly corresponding to a second communication state of a portable communication device according to an embodiment of the present invention. The lower figure is a top view, and the upper figure is sectional drawing of C-C. In the sectional view, the spring 50 is omitted.

3 is a final state in which a force is applied to move the second hinge part 20 upward in FIG.

In FIG. 1, when the force is applied upward to the second hinge part 20, the roller 30 positioned in the stop groove 12 overcomes the force of the tension spring 40 and is separated from the stop groove 12. It is automatically moved upward by the force accumulated in the spring 50.

3 corresponds to a second communication state of the mobile communication device, and the LCD panel portion of the slide mobile phone is connected to the first hinge part 10, and the keypad portion is connected to the second hinge part 20. If the addition moves to the bottom, the function was not implemented in the existing slide type mobile phone.

In the second communication state of FIG. 3, the keypad may also be disposed on the keypad, and the keypad disposed on the keypad may be used. A video call, a DMB viewing, and an MP3 listening function, which are performed in the existing slide mobile phone, may be performed in the second communication state.

Figure 4 is a plan view showing another form of the stop groove in one embodiment according to the present invention.

Referring to Figure 4, the top of the stop groove 12 formed in the first hinge part 10 is inclined rapidly, the bottom is formed inclined gently.

The inclination of the upper part of the stop groove 12 is urgent because the roller 30 of FIG. 1 moves upward by the compression force of the spring 50 immediately after leaving the stop groove 12 so that the inclination is steep For force must be exerted.

The inclination of the lower portion of the stop groove 12 is gentle, even if the roller 30 of FIG. This is because it is difficult to open by unexpected external forces.

1 to 4, the stop groove 12 is formed on the side of the first hinge part 10, and the tension force generated by the tension spring 40 is applied to the roller 30 to the second hinge part 20. By using the coupling force of the stop groove 12 and the roller 30, a new state was further created.

In another embodiment of the present invention may use a compression spring instead of the tension spring (40).

For example, one sliding part of the second hinge part 20 is made large and a stop groove is formed in the sliding part.

The first hinge part 10 is formed by forming a ring, positioning the compression spring, and mounting a roller at the end of the compression spring, so that the roller corresponds to the stop groove formed in the sliding part. The same effect as in one embodiment can be seen.

In this case, when a compression force is applied to the compression spring, the compression spring may be twisted by the compression force, but this can be overcome by forming the ring long into the compression spring. In addition, it is possible to minimize the increase in thickness by making the compression spring into a flat rectangular shape.

As described above, according to the present invention, a function that is performed by using a first communication state (call state), such as a video call, DMB viewing, and MP3 listening, can be performed by using a second communication state, thus completely opening the mobile phone. The effect is that you can perform the functions you want without having to.
