[0001] PORTABLE TERMINALS WITH DUAL SCREENS [0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a dual screen portable terminal, and more particularly, to a dual screen portable terminal having a movable structure that allows two terminals constituting a dual screen portable terminal to be connected to each other and move freely.

[0002] Recently, portable terminals have been advancing to replace the computers because they are able to access the Internet, and they are collectively referred to as smart phones. The screen of a portable terminal corresponding to a computer monitor screen is now being enlarged to about 6 inches. The size of the portable terminal screen is not uniformly standardized. If the size of the screen is large, the portable terminal screen can be used as a multi-tasking application or a tablet PC using various applications. However, an excessively large screen is a factor that hinders the usability of the portable terminal regardless of the thickness of the portable terminal.

If the screen of the portable terminal is dual, the advantage of the large screen can be utilized without hindering the convenience of the portable terminal. Currently, a method of dualizing a screen of a mobile terminal is to implement a dual screen by configuring two mobile terminals, each having its own screen, instead of implementing two screens in the body of one mobile terminal. Thus, in the present specification, a dual screen refers to a dual screen implemented by two portable terminals.

 At the Mobile World Congress (MWC2013) held in 2013, NEC unveiled a dual-screen smartphone that is implemented as two handheld terminals. In the case of a dual screen smartphone disclosed by NEC, two portable terminals are connected by a hinge, and one of two terminals overlapped with each other is deployed at a required angle.

In a dual screen handheld terminal, it is desirable for each screen to be freely positioned relative to each other for various uses of each screen. To this end, there is a need for a fastening device which is required to be able to move freely between two portable terminals, and which can be stopped while being moved to a necessary position.

It is an object of the present invention to provide a dual screen portable terminal in which two portable terminals having respective screens are connected to each other and can freely move.

In order to achieve the above object, according to the present invention, there is provided a mobile communication terminal comprising: a pair of side-by-side railway passageways formed to face each other at the upper and lower outer edges of two portable terminals; Type portable terminal having a movable structure composed of a pair of connection terminals. According to the structure of this movable structure, the two portable terminals can be moved with respect to each other while being bound to each other by the I-type connector.

It is preferable that a horizontal tooth is formed at both ends of the orbit passage. The I-shaped connector includes a pair of cylindrical bodies and a connecting member connecting the bodies. The I-shaped connector has an I-shaped cross section, and a hollow portion is formed in the body so as not to communicate with each other by the inner middle partition, I-shaped member, and I-shaped member, and at one end thereof, there is formed a horizontal tooth which engages with the teeth of the track, and the other end is opened to form a hollow portion, And a spring positioned in the hollow portion of the I-shaped member and the end member. With this arrangement, the I-type connector is controllably linearly moved along the track path, but can be smoothly moved by the elastic force of the spring.

On the other hand, the body of the I-shaped member has a disk shape and has a bevel tooth formed on the lower surface of the disk along the circumferential direction and on which the connecting member is positioned; It is preferable that one side of the cylinder is formed with an intermediate member in which a bevel tooth to be engaged with the teeth of the rotary member is formed and the other side of the cylinder is opened to form a hollow portion. With such a configuration, the I-type connector can move smoothly along the track path while simultaneously moving smoothly.

A support rod is formed at the center of the rotary member and a through hole is formed at the center of the intermediate member to insert the support bar. Such a configuration prevents the rotating member from falling off from the intermediate member. In addition, it is preferable that an incision strip extending from a direction in which the hollow portion of the intermediate member is opened is formed at the outer side of the intermediate member, and a band projection is formed in the hollow portion of the end member to be inserted into the incision band. This configuration prevents the intermediate member from rotating together along the rotating member during rotation of the rotating member.

The movable structure further includes a locking device for stopping the operation of the movable structure. At this time, the locking device includes a linear locking member extending through a circular hole formed in the connecting member. The circular through-hole and the locking member of the connecting member are engaged with each other by screws. When the locking member is rotated in one direction, the upper and lower connecting members are engaged with each other by the upper and lower thread portions. Therefore, when the locking member is rotated in the locking direction, the connecting members move closer to each other, which causes the end members of the I-type connector to come into close contact with the track passage, thereby stopping the operation of the movable structure.

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

FIG. 1 is a perspective view of a dual screen portable terminal having a movable structure according to the present invention, and FIG. 2 is a sectional view taken along a direction A-A of FIG.

The illustrated dual screen portable terminal 1 is composed of two portable terminals 2 and each of the portable terminals 2 is provided with a respective screen 6 so that the dual screen portable terminal 1 has two screens do. These two portable terminals 2 can mutually move while being held together by the movable structure according to the present invention, and the movable structure of the present invention will be described below.

As shown in Fig. 2, the movable structure of the present invention comprises a planar orbital passage 5 formed in the main body of each portable terminal 2, a cross section I (i) located in the orbital passage and movable along the orbital passage, Type connector 20 as shown in FIG.

The orbit passage 5 is formed so as to be opposed to the outer circumferences of the upper and lower ends of each portable terminal 2 and includes a passage 4 extending to the surface of the portable terminal and opening to the surface of the portable terminal, And a passageway (3) extending parallel to the surface of the portable terminal on both sides at the inner end of the portable terminal. At both ends of the passage 3, a horizontal tooth 7 is formed.

3 is a perspective view of the I-shaped connector 20 according to the present invention, and a part thereof is shown in an exploded perspective view.

The I-shaped connector 20 is composed of an I-shaped member 21, a terminal member 30 positioned at each end of the member 21, and a spring 27.

The I-shaped member 21 is composed of a pair of cylindrical bodies 22 and a connecting member 25 connecting the moving bodies, and has an I-shaped cross section. The moving body 22 has a hollow portion 23 that is opened only in each end direction. Since the hollow portion 23 is opened only in the end direction of the moving body 22, two hollow portions 23 are formed in the moving body 22, and the hollow portions 23 do not communicate with each other due to the inner intermediate partition. The connecting member 25 is provided with a circular through hole 26 into which a locking member 11 as described later is inserted, and a screw is formed in the inner periphery of the through hole.

The end member 30 is a member located at each end of the above-described I-shaped member moving body 22 and has a cylindrical shape. At one end of the cylindrical member, a horizontal tooth 33 is formed to engage with the toothed passage 7, and the other end is opened to form a hollow portion 31 therein. An end of the I-shaped member body (22) is inserted and positioned in the hollow portion (31). Therefore, the hollow portion 23 of the I-shaped member 22 and the hollow portion 31 of the end member 30 are communicated with each other, and a spring 27 (not shown) is formed in the space defined by these hollow portions 23, ).

Since the ends of the body 22 are inserted into the end members 30 as described above, both ends of the I-shaped connector 20, that is, the end members 30 and the body 22 are inserted into the passages of the orbital passages 5 Type connecting port 20 is not separated from the track 5 and the connecting member 25 extends through the passageway 4 so that the two portable terminals are held in a state of being engaged with each other (See Fig. 2). Furthermore, the end members 30 of the I-shaped connector 20 can make a linear movement along the passage 3 of the orbital passageway 5. 2, when the other portable terminal 2 is moved while holding one portable terminal 2 by hand, the end member 30 of the I-type connector 20 is moved to the orbit passage (not shown) 5 along the passageway 3 thereof. When one end of the body 22 is inserted into the end member 30 and the dimensions thereof are adjusted so as to smoothly rotate while being inserted, one portable terminal 2 is moved to the other portable terminal 2 So that it is possible to perform rotational motion with respect to the above-

In the illustrated embodiment, a tooth 7 is provided at both ends of the orbit passage 5 and a horizontal tooth 33 is formed in the end member 30 of the I-shaped connector 20 so as to be engaged with the tooth 7 So that there is a frictional resistance between the teeth 7, 33 when the end piece 30 moves along the passage 3 of the orbital passageway 5. Thus, the I-shaped connector 20 does not move freely along the orbital passageway 5, On the other hand, since the frictional resistance between the teeth 7, 33 is resiliently received by the spring 27 located in the hollow portions 23, 31, the I-shaped connector 20 is controlled to some extent along the track path 5 And move smoothly.

The movable structure 5 (20) of the present invention as described above preferably includes a locking device for stopping the operation of the movable structure. 4 is a perspective view showing a movable structure 10 in which a locking device is realized by a locking member 11 extending through two I-shaped connecting ports 20 located at the upper and lower ends of the portable terminal 2. [

The locking device according to the present invention is characterized in that a linear locking member 11 is inserted into a circular through hole 26 formed in a connecting member 25 of an I-type connecting port 20 and an inner circumferential surface of the through- And the through hole 26 and the lock member 11 are screwed into each other. The upper and lower connecting members 25, i.e., the I-type connecting ports 20 are in close proximity to each other when the locking member 11 is rotated in one direction by screws whose threads on the upper and lower outer circumferential surfaces of the locking member 11 are opposite to each other. (Or away) from the surface. For example, the upper and lower lock pieces 11 may be provided with a left turn screw on one side and a right turn screw on the other side around the center of the upper and lower lock pieces 11, A screw in the same direction is formed and a screw in the opposite direction is formed inside the through hole 26. Therefore, when the locking member 11 is pivoted in one direction by holding the knob 13 and the I-shaped coupling 20 is moved close to (or away from) the I-shaped coupling 20, One of which is in close contact with either one of the ends of the passage 3 of the orbit passage 5. This stops the operation so that the movable structure can not move.

As described above, when the dual portable terminal 1 is provided with the movable structure 5 (20) according to the present invention, each of the portable terminals 2 can freely linearly and rotationally move with respect to each other, The user of the portable terminal 2 can position the screen 6 of each portable terminal 2 at a desired position. For example, in the state shown in Fig. 1 in which each screen 6 is positioned in the same direction (in this state, only one screen can be used), the upper and lower portable terminals 2 are moved linearly , The screen 6 can be positioned in the same state as the book is opened as shown in Fig. In this state, the two screens 6 can be used as one large screen. When the locking device is used after rotating any one of the portable terminals 2 in the desired direction in the desired direction with respect to the other portable terminal 2 in the state shown in FIG. 7, as shown in FIG. 8, The screen 6 of the portable terminal 2 can be kept rotated at the necessary angle with respect to each other. In this state, the following portable terminal screen 6 can be used as a keyboard, so that a dual screen portable terminal can be used as a very small notebook. Furthermore, when the linear motion and the rotational motion are properly combined, the screen of each terminal is stopped so as to face each other as shown in FIG. 9, and the screen of each terminal is stopped as shown in FIG. 10 Lt; / RTI > In the state shown in FIG. 10, the two portable terminals can be used as independent terminals according to their respective needs. As described above, when the movable structure according to the present invention is provided, the screen of the dual portable terminal 1 can be positioned at a desired position, and the usability of the dual portable terminal can be remarkably increased.

Fig. 5 is a perspective view corresponding to Fig. 3 as a second embodiment of the I-shaped connector of the movable structure according to the present invention.

The illustrated I-shaped connector 20 'consists of an I-shaped member 21', a distal member 30 'located at each end of the member 21', and a spring 27.

The I-shaped member 21 'corresponds to the I-shaped member 21 of the I-shaped connector 20. The difference between the two is that the portion corresponding to the moving body 22 of the I- 22 'and an intermediate member 35 as shown in FIG.

The rotary member 22 'is disk-shaped and has a bevel tooth 29 formed on its lower surface along the circumferential direction, and a connecting member 25 having a circular hole 26 is located on the side surface. At the center of the rotary member, a central support rod (24) projects upwardly and downwardly.

The intermediate member 35 has a cylindrical shape and is positioned on the upper and lower surfaces of the rotary member 22 '. On one side of the cylinder of the intermediate member 25 is formed a bevel tooth 37 engaging with the tooth 29 of the rotary member and the other side of the cylinder is opened to form the hollow portion 36. A central through hole 39 into which the support rod 24 is inserted is formed at the center of the side of the intermediate member 25 on which the tooth 37 facing the rotary member 22 'is formed. A cutout band 38 is formed on the outer side of the intermediate member 35 and extends along the outer side from the direction in which the hollow portion 36 of the intermediate member is opened.

The end member 30 'of the I-shaped connector 20' has the same configuration as that of the end member 30 of the I-shaped connector 20 and is formed inside the hollow portion 31 of the end member 30 ' Only the band protrusion 32 is formed which is inserted into the cut-off band 38 of the cutter 35.

In the I type connector 20 ', the spring 27 is located in the space defined by the intermediate member 35 and the hollow portions 36 and 31 of the end member 30', and the rotational member 22 ' (35) is connected by the support rods (24) to prevent the rotary member from separating from the intermediate member. Since the teeth 29 and 37 of the rotating member and the intermediate member are engaged with each other when the rotating member 22 'is rotated, the rotational motion of the rotating member 22' relative to the intermediate member 35 is caused by friction between the teeth It is rotated with a certain degree of control. This rotational motion is accommodated by the spring 27 in a resilient manner. On the other hand, since the cutting member 38 of the intermediate member and the insertion band 32 of the distal member 30 'are engaged with each other, the intermediate member 35 is inserted into the hollow portion 31 of the distal member 30' The intermediate member is prevented from rotating together with the rotary member only by elastic movement along the longitudinal direction of the end member 30 '. Accordingly, in the movable structure using the I-type connector 20 ', the I-shaped connector 20' can be smoothly linearly moved and smoothly rotated while being controlled to some extent along the orbital passage 5.

The I-shaped connector 20 '' shown in FIG. 6 is the same as the I-shaped connector 20 'except that one intermediate member 35' 'is longer than the other intermediate member 35' Except that the spring 27 'received in the hollow portion of the member 35' 'is longer than the spring 27 received in the hollow portion of the short intermediate member 35'. At this time, the long intermediate members 35 " are located in opposite directions or in opposite directions in the two I-shaped connectors 20 ". That is, the long intermediate member 35 '' is located on the left side of the right I-shaped connector 20 '' and on the right side of the left I-shaped connector 20 '' (FIG. 6) ') And to the right of the left I-shaped connector 20' '. In the case of the movable structure 10 'composed of the I-shaped connector 20' 'having such a configuration, when the locking device 11 is rotated in the axial direction, the long intermediate member 35' The operation of the movable structure can be quickly stopped by urging the movable member 30 'so that the end member 30' quickly comes into contact with the passage 3 of the orbital passage 5.
