In addition, by configuring a button for operating such a locker device on the upper end of the terminal, the lock is released even when falling, shock or vibration, there is an effect that the folder is not opened to give structural stability.

Hereinafter, exemplary embodiments of the present invention will be described with reference to the accompanying drawings.

1 is a perspective view showing the appearance of a mobile communication terminal in a completely closed state according to an embodiment of the present invention. Referring to the drawings, a locker device according to an embodiment of the present invention, a folder portion 100 is composed of a display panel and operation keys, and a sliding portion 200 that is opened and closed by sliding from the folder portion 100, It has a rocker button 110 for opening and closing the slinging unit 200.

Folder unit 100 is configured on the front of the terminal, and is provided with a display panel and operation keys for providing a screen to the user. In addition, the folder part 100 is opened to be spaced apart from the sliding part 200, a view showing this is shown in FIG.

The sliding part 200 corresponds to the body of the terminal and is opened to be spaced apart from the folder part 100. Of course, the inside of the sliding unit 200 has a key input unit (not shown) consisting of a key button engraved with Korean, numerals, and English letters. The key input part is exposed while the sliding part 200 is spaced apart from the folder part 100 and opened downward. Therefore, in the closed state where the folder part 100 and the sliding part 200 are completely matched, the key input part is not visible.

The locker button 110 is configured in the folder part 100 to open and close the sliding part 200. The locker button 110 is placed on the top of the folder unit 100 to facilitate the user.

FIG. 2 is a cross-sectional view illustrating a plane cut along the line AA ′ of FIG. 1. That is, the folder part 100 is cut along the longitudinal axis A-A 'axis, and the figure shows a locker structure for opening and closing the sliding part 200.

Referring to FIG. 2, the locker button 110 is shown at the top of the folder unit 100. The rocker button 110 is installed to be movable up and down and is a means for moving the sliding part 200 up and down. Of course, for this purpose, there is provided a shangdong means for moving up and down according to the operation of the locker button 110, and the left and right moving means for moving left and right as the shanghai means moves up and down.

First, the Shanghai East means, the Shanghai East means is composed of the upper bar 122 connected between the locker button 110 and the Shanghai East body 124, and the lower bar 126 for guiding the Shanghai East of the Shanghai East body. do. Of course, the locker button 110 is formed with a departure prevention jaw 112 to prevent the locker button 110 is separated from the folder portion (100). Therefore, the departure prevention jaw 112 is preferably formed in a slightly larger edge than the locker button (110).

Next, looking at the left and right moving means, the left and right moving means is moved left and right as the Shanghai body 124 moves up and down. To this end, an arm 130 moving in the lateral direction and a stop locker 142 connected to the arm 130 to perform a locker function are provided. Of course, the arm 130 and the stop locker 142 are present in the left and right symmetry based on the Shanghai body 124.

Of course, in order to move the arm 130, which belongs to the left and right moving means to the outside, the chamfer is performed on the lower outer side of the shank body 124 to form an inclined surface. An inclined surface in contact with the inclined surface of the shanghai body 124 is formed at the inner end of the arm 130.

Therefore, when the locker button 110 is pressed in a state in which the sliding part 200 is closed, the inclined surface of the shanghai body 124 is in contact with the inclined surface of the arm 130 while the shanghai body 124 descends downward. As it is pushed, the arm 130 is pushed outward.

In other words, the arm 130 is pushed outward and the sliding part 200 is directed downward to open. That is, the locker is released. The figure showing such a rocker structure is an enlarged view of the circular dashed line shown on the right side in FIG. Of course, this figure shows before the sliding portion 200 is still sliding in a closed state.

Looking at this, the lower bar 126 is moved downward when the locker button 110 is pressed, the lower bar 126 is fixed to provide a reference axis to the Shanghai body 124, the upper part is fixed, It will be pulled in. To this end, the Shanghai body injection groove 124-1 is formed at the lower end of the Shanghai body 110. Therefore, the shanghai body injection groove 124-1 performs a guide function so that the shanghai body 124 is stably shangdong.

As mentioned above, when the inclined surface of the shank copper body 124 and the inclined surface of the arm 130 are in contact with each other, when the locker button 110 is pressed, the arm 130 is pushed outward. When the arm 130 is pushed outward and moved, the locking protrusion 210 moves downward. The locking protrusion 210 is to allow the sliding part 200 described in FIG. 1 to be opened and closed with the folder part 100.

That is, the locking protrusion 210 protrudes from the front surface of the sliding part 200 and is interpolated into the folder part 100, and is locked or released by the locker so that the sliding part 200 moves up and down with respect to the folder part 100. To control.

When the locking protrusion 210 is located on the basis of the stop locker 142, the folder 100 and the sliding part 200 show a closed state that is completely matched. On the contrary, when the locking protrusion 210 moves downward based on the stop locker 142 and shows the open state, the folder part 100 and the sliding part 200 are completely spaced apart. An embodiment showing this is shown in FIGS. 3 and 4. This will be described in the corresponding drawings.

Thus, a locker composed of the stop locker 142 and the pass locker 146 is formed. Here, the stop locker 142 contacts the lower end of the locking protrusion 210 when the locker button 110 is not in operation, thereby preventing the sliding part 200 from being moved to the lower side of the folder part 100. At this time, the locking projection 210 is formed at the lower end of the locking protrusion 210 in accordance with the operation of the locker button 110 to form a recess groove between the outer end of the arm 130 and the stop locker to be movable downward. It becomes the pass locker 146. A diagram showing this is shown in FIG. 7.

The stop locker 142 is provided with a groove inward in the shape of the letter "c" (character). In addition, the passage locker 146 is formed with a recess groove 148, the locking projection 210 is a guide that passes upward or downward in the upward direction or downward.

Of course, chamfering is performed on the upper outer side of the locking protrusion 210 to form a locking protrusion slope, and the stop locker 142 is also formed of a stop locker slope.

5 is a diagram showing this, and FIG. 5 shows a state where the locking protrusion slope of the locking protrusion 210 and the stop locker slope of the stop locker 142 are in contact with each other.

In particular, a view showing a stop locker slope of the stop locker 210 is shown in FIG. 7. That is, when the locking protrusion 210 moves from the bottom to the upper side in the state in which the sliding part 200 is opened, the letter “c” is shaped so that the stop locker 210 moves outwardly in contact with the locking protrusion slope. Chamfering is performed on the lower inner side in the shape to form the stopper lock slope.

Referring to FIG. 5 together, when the locking protrusion 210 completely passes through the recess groove 148 of the passage locker 146, the stop locker 142 so that a force for pushing the stop locker 142 inwards is applied again. And a compression spring 144 is provided between the closed sidewall of the stop locker guide groove 143.

 Therefore, when the user ends the use of the terminal in the sliding state shown in FIG. 3 and pushes the sliding part 200 upward, the locking protrusion slope of the locking protrusion 210 pushes the stop locker slope of the stop locker 142. Is raised and lowered. 3 is a perspective view showing a state in which the body of the mobile communication terminal is slid downward in accordance with an embodiment of the present invention.

This will be described in detail to explain the opening and closing operation. First, the opening operation will be described. When the user presses the locker button 110 in the folder unit 110 in the closed state illustrated in FIG. 1, the arm 130 shown in FIG. Is passed through the recess groove 148 formed in the pass locker (146). Therefore, the sliding part 200 is fully slid to an open state, which is shown in FIG. 3. FIG. 4 is a cross-sectional view showing the cut surface of the B-B 'axis in FIG.

Of course, in this case, when the locker button 110 is pressed due to the load of the sliding part 200, the stopper lock 142 moves outwards, so that the locking protrusion 210 penetrates through the recessed groove 148 of the pass locker 146. It will descend in the downward direction. Therefore, the sliding part 200 is spaced apart from the folder part 100 to be in an open state.

Next, when the closing operation is described, when the user pushes the sliding part 200 shown in FIG. 3 in the upward direction, the locking protrusion 210 moves upward while moving the stop locker 142 in FIG. 1. . Of course, for this purpose, as described above, an inclined surface is formed on one side of both the stop locker 142 and the locking protrusion 210. Therefore, as the stop locker 142 is moved outwards, the pass locker 146 also moves, so that the locking protrusion 210 can penetrate the recessed groove 148 in the pass locker 146. A diagram showing this is shown in FIG. 6.

Of course, when the locking protrusion 210 is completely penetrated, the stop locker 142 is moved back to the inside by the restoring force of the compression spring 144. Therefore, the locking protrusion 210 is caught by the stop locker 142. Therefore, a state of occlusion is shown, which is shown in FIG. 1.

In one embodiment of the present invention, but the user described as the locking projection 210 sliding the passage locker 146 completely upward by the closing operation, it is also possible to have a spring on the inner side to automatically slide only if a certain force is applied. .

 Since this has already been disclosed, only the principle will be described briefly. That is, one end of the torsion spring is fixed to both sides of the main body of the terminal, and the other end of the torsion spring is fixed to the slider that is slidably coupled to the main body so that the slider is configured to move by the elasticity of the torsion spring. to be. This is described in Patent Application No. 066670 "Slide opening and closing device of a portable terminal" (Applicant: LG Electronics Co., Ltd.).
