Mobile Telephone Turnable Folder Over}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mobile phone capable of inverting folders, and in particular, to reverse a folder so that one LCD screen can be closed inward or outward, so that a liquid crystal can be opened without using a folder while the mobile phone is not in use. It's about a mobile phone that can flip a folder so you can see the screen.

Mobile phones, commonly referred to as mobile phones, cellular phones, PCS phones, personal mobile phones, and wireless terminals, can carry voice calls or send and receive text messages with the other person while carrying the individual, and can access the Internet. It is a convenient mobile terminal that is always near in life.

These mobile phones have been developed in a form that allows them to be portable and used for more convenient and versatile purposes because they are frequently carried and used frequently in everyday life.

As one of the techniques conventionally employed for the user's convenience, it is commonly known to say a dual folder, and the dual folder refers to having an LCD screen on the outer side of the folder.

Such a conventional dual folder has an LCD screen on both sides of the folder, so that the user can check the information such as date, time, text message, etc. because the user can see the LCD screen without opening the folder in the standby state when the user does not use the mobile phone. However, the user's convenience is provided, but the thickness of the folder is increased by providing the LCD screen on both sides.

In addition, the above-described dual folder format may be contrary to the user's taste or usage environment because the LCD screen is always exposed to the folder surface regardless of the user's intention. For example, if the LCD screen is hit by the surroundings and is likely to be damaged, such as when performing a somewhat active task, the LCD screen must be exposed as it is. Therefore, what is provided for the user's convenience returns to inconvenience or burden to the user. There is an absurdity that comes.

SUMMARY OF THE INVENTION The present invention has been made in view of the above, and an object of the present invention is to provide a folder with only one LCD screen so that the folder thickness can be reduced and the folder can be rotated to close the user's taste or use situation. According to the present invention, it is possible to protect the LCD screen by closing the LCD screen inward, and to provide a mobile phone capable of inverting a folder so that the LCD screen can be checked even when carrying by closing the LCD screen outward.

In order to achieve the above object, a mobile phone capable of inverting a folder according to the present invention includes a case comprising an input key and a case constituting the phone body, and a folder coupled to the case so as to be openable and openable on one surface thereof. In the telephone, the support shaft is provided at one end of the folder, the end of the support shaft is provided with a spherical rotation center, and at one side of the case is provided with a receiving groove in which the rotation center body is rotatably received. In addition, the upper portion of the receiving groove of the case, the support shaft is characterized in that it is provided with a guide hole that is passed in a state capable of moving in the front and rear opening and closing direction.

In the present invention, the rotation center is accommodated in the receiving groove of the case so that the folder can be rotated in the vertical opening and closing direction and rotation in the left and right reverse direction from the center of the rotation center.

Hereinafter, the most preferred embodiment of the present invention will be described in more detail with reference to the accompanying drawings, FIGS. 1 to 9.

As shown, the mobile phone is provided with a case 10 and a folder 30. The case 10 forms a phone body, and a battery 50 is mounted at a lower side thereof, and an input key 12 is provided at an upper side thereof. Lose. The folder 30 is connected to the case 10 in an open and closed manner, and a liquid crystal screen 32 is provided on one surface thereof.

In particular, in the mobile phone capable of reversing folders according to the present invention, a support shaft 34 is provided at one end of the folder 30, and a rotation center 60 is provided at the end of the support shaft 34. One side of the case 10 is provided with a receiving groove 14 for rotatably receiving the rotation center body 60.

The rotating center body 60 is rotatably inserted into the receiving groove 14, the receiving groove 14 side is formed with a guide through-hole 16 in the opening and closing direction of the folder 30, the support shaft 34 ) Rotates up and down in the guide hole 16 around the rotation center 60 to open and close, and the support shaft 34 rotates left and right with the rotation center 60 to provide the liquid crystal in the folder 30. The screen 32 is configured to be inverted and opened.

Preferably, the rotation center 60 is spherical as shown, and corresponding to the receiving groove 14 is also spherical.

As such, the rotational core 60 and the receiving groove 14 may be said to have the most preferable sphere in view of smooth operability and convenience of manufacturing. It may be formed in the form, or may take the form of a polygon, such that the center of rotation 60 in the receiving groove 14 can be configured to vary its shape within the range that can be rotated back and forth and left and right. Further, the receiving groove 14 also has a variety of forms, such as not only spherical within the range that can be rotated on the rotation center 60, for example, to form an ellipse to maintain the rotation center 60 in the center of the ellipse. It can be modified and applied.

According to a preferred direction of the present invention, the case 10 is divided into a lower case 10a on which the battery 50 is mounted and an upper case 10b on which the input key 12 is provided to be coupled to each other. The lower case 10a and the upper case 10b thereof are formed such that the split surface PL passes through the center of the receiving groove 14. That is, the receiving groove 14 is formed in each of the lower case (10a) and the upper case (10b) each half, so that the assembly of the rotation center (60) can be made easily.

However, in the present invention, injection molding the rotary core 60 and the case 10 at the same time without dividing the receiving groove 14, or forming a hole in the case 10, and inserts the rotary core 60 After the heat is applied, the method of crimping the entrance of the hole is not excluded at all.

In addition, in the preferred embodiment of the present invention, the rotation center 60 is not integrally formed on the support shaft 34 on the side of the folder 30 is provided as a separate member.

In particular, as shown in Figs. 3, 5A and 5B, the rotation center 60 is divided in half while maintaining the clearance (d) in which the support shaft 34 is rotated therebetween, so that the first rotation center body 62 and the second rotation center 64, the center of the divided first rotation center 62 and the second rotation center 64 is detachably coupled by the coupling shaft (66). In the illustrated example, the coupling shaft 66 is formed in the second rotational core 64, and the shaft 68 inserted into the coupling shaft 66 hole 66a is formed from the center of the first rotational core 62. It is arranged.

Alternatively, in the present invention, the coupling shaft 66 is formed on one side of the rotational core divided in half, and the other rotational core may form a hole to be coupled to each other, or the coupling shaft 66 may be separately provided. A hole is formed in each of the centers of the first and second rotation centers 62 and 64 so that the coupling shaft 66 provided separately may be inserted into the center hole of the first and the second rotation centers 62 and 64 to be assembled. I never do that.

In addition, an end portion of the support shaft 34 of the folder 30 is formed with an annular body 36 rotatably fitted to the coupling shaft 66, and through the hole 36a of the annular body 36. The coupling shaft 66 is rotatably coupled.

Thus, when opening and closing the folder 30, the ring body 36 may rotate on the coupling shaft 66, regardless of whether the rotary center 60 is rotated, and rotates the folder 30 in the left and right directions. Only when making the rotation, the center of rotation 60 is forcibly rotated.

Such a configuration prevents the rotation center 60 from making a lot of unnecessary sliding, and will be described later, but easily connects a wire for transmitting power and a signal of the case 10 and the folder 30 and connects the wire. And while allowing the rotation of the folder 30, the folder 30 plays a basic role of preventing the wire from being twisted as much as possible.

In addition, according to an embodiment of the present invention, the wire 2 is twisted even if the rotation center 60 is rotated while more easily connecting the wire (2) connecting the lower case (10a) and the upper case (10b). The preferred wire 2 connection structure is shown in detail in Figures 3 and 7A-7D.

As shown in the figure, a configuration for connecting the wires 2 from the case 10 side to the folder 30 side, and communicates with the inside of the folder 30 inside the support shaft 34 of the folder 30. The shaft hole 38 is formed, and the through hole 40 penetrating the shaft hole 38 from the outside of the support shaft 34 is formed, and the case 10 has the first and second rotation center bodies 62 and 64. Wire passing hole 18 is formed in communication with the gap (d) between. A gap d formed between the first and second rotation center bodies 62 and 64 while the wire 2 from the case 10 side extends into the receiving groove 14 through the wire through hole 18. The through hole 40 and the shaft hole 38 of the support shaft 34 are sequentially connected to the inside of the folder 30.

In addition, in the present invention, the flat portion 70 is formed on both sides of the rotation center body 60, that is, outside the first and second rotation center bodies 62 and 64 orthogonal to the opening and closing direction of the folder 30. Both sides of the case 10 are provided with an elastic pressing body 80 which protrudes into the receiving groove 14 to press the flat portion 70 elastically.

As such, by pressing the flat portion 70 of both sides of the rotational core 60 elastically against the elastic pressing body 80, the rotational core 60 can rotate in the left and right directions only when a force greater than or equal to the pressing force is applied. Will be. As a result, the left and right movements of the rotation center body 60 are prevented, so that the opening and closing operation of the folder 30 can be more stably and accurately performed. In particular, the folder 30 is arbitrarily rotated left and right against the user's intention during opening and closing. Can be prevented.

In the illustrated embodiment, the elastic pressurizer 80 is composed of a spring 82 and a plunger 84 elastically supported by the spring 82 to contact the flat portion 70 of the rotation center body 60. In the divided surface PL of the lower case 10a and the upper case 10b, half receiving parts 20a and 20b are provided in each case 10a and 10b to be installed thereon.

In addition, the elastic pressing body 80 is a gap d between the first and second rotation centers 62 and 64 when the rotation center 60 is divided into the first and second rotation centers 62 and 64. Its diameter is made larger than the gap d so as not to get caught in).

In addition, in the present invention, the guide protrusion 22 is formed from the receiving groove 14 of the case 10, and the circumferential circumference of the first and second rotary centers 62 and 64 is the folder 30. In the fully open state, a groove 72 is formed in which the guide protrusion 22 is slidably inserted in a direction orthogonal to the axis X of the support shaft 34. By the coupling of the guide protrusion 22 and the groove 72, the first and second rotary centers 62 and 64 do not rotate when the folder 10 is opened and closed, and the folder 10 rotates in the left and right directions. Only when it is possible to rotate, and also the folder 30 can be rotated only in a fully open state.

In addition, the elastic pressing members 80 on both sides are disposed on the same axis connecting the center of the rotation center 60 and the axis X of the support shaft 34 in a fully open position of the folder 30, It is arranged spaced apart from each other in a position symmetrical up and down with respect to the center of the rotation center 60, and one side of the flat portion 70 of the rotation center 60, respectively, the elastic pressing body (80) on both sides Two jaws (74a, 74b) are formed to be caught on the side of the rotation stop.

The jaw portions 74a and 74b are excluded by forming the flat portion 70 except for the portions of the surfaces of the first and second rotational core bodies 62 and 64 that contact the side surfaces of the elastic pressurizer 80. And the stepped portion is formed by the height difference between the flat portion 70, and in particular, as shown in FIGS. 7C, 7D and 8, the central axis X formed by the support shaft 34 of the folder 30 and A line connecting the center of the rotation center 60, that is, symmetrical in the diagonal direction from the rotation center axis of the rotation center body is formed to contact the outer surface of both elastic pressing body (80).

As described above, the jaw portions 74a and 74b are the flat portions 70 on one side of the flat portions 70 formed on both sides of the rotation center body 60, that is, the rotation center body 60 is the first and second rotation center bodies 62. (64), both should be formed only in one of the rotating cores. In the illustrated example, the first rotary center 62 is formed.

In particular, referring to Figure 8, when rotating the rotation center body 60 to invert the folder 30, as shown in the upper portion, the lower jaw portion 74a is the lower elastic pressing body ( 80, shown as a solid circle, may not rotate to the left, but may rotate only to the right, that is, in the direction of the solid arrow.

As such, when the rotation center body 60 rotates to the right side, the lower jaw portion 74a is not caught by the elastic pressing body 80 on the opposite side shown by the dotted line circle, but is shown at the lower side as soon as it crosses the 180 degree angle. As shown in the figure, the upper jaw portion 74b is no longer rotated by being caught by the elastic pressurizer 80 in a dotted line. In this state, it is possible to rotate only in the direction of returning to the direction in which the rotation center body 60 is rotated, i.e., only to the left, which is the direction of the arrow of the dotted line in the lower figure. In the lower drawing, when the rotational core 60 is rotated in the direction of the dotted arrow, and the rotation exceeds an angle of 180 degrees, as shown in the upper drawing, the lower jaw portion 74a is in front of the solid line elastic pressure body. The rotational core 60 and the folder 30 cannot continue to rotate more than half a turn in the same direction by being caught by 80 and no longer rotated.

Preferably, the jaw portions 74a and 74b should be formed at a position where the rotational core 60 can be rotated by at least 180 degrees or more so that the folder 30 is not rotated less. The opening and closing operation of the folder 30 should be stable at most at a position not exceeding an angle of 190 degrees.

When the rotational core 60 can be rotated by more than 190 degrees, the clearance d formed by the first and second rotational cores 62 and 64 and the guide hole 16 of the case 10 are not aligned. When it is displaced and closes the folder 30 again, an excessive force is applied to the support shaft 34 and the guide through hole 16 of the folder 30 by the force forcing the rotation of the rotational core 60. When the rotational core 60 is rotated to a degree close enough, it becomes very difficult to close the folder 30 without rotating the folder 30 to its normal position in advance. That is, when the folder 30 is rotated more and tries to close the folder 30 as it is while the gap (d) and the guide hole (16) are displaced much, the direction in which the gap (d) and the guide hole (16) are misaligned is the same. As the rotation center 60 and the folder 30 is closed while being rotated, the support shaft 34 of the folder 30 is in close contact with the side wall of the guide hole 16 by the repulsive force, causing friction.

In order to accurately maintain the rotation range of the rotation center 60 at an angle of 180 degrees, it is possible to form the sides of the two jaw portions 74a and 74b at positions corresponding to the sides of both elastic pressurizers 80, respectively, As the jaw portions 74a and 74b are located farther from the side surface of the pressing member 80, the rotation range of the rotation center body 60 exceeds 180 degrees. Preferably, a slight gap is provided between the jaw portions 74a and 74b and the elastic pressurizer 80 so that the rotation angle slightly exceeds 180 degrees.

The mobile phone capable of inverting the folder of the present invention made as described above is used while opening and closing the folder 30 in the up and down direction with the LCD screen 32 inward in a normal use state, otherwise the folder 30 is used. The LCD screen 32 may be rotated in the horizontal direction to face the inside or outside of the folder 30.

7A and 7B, with reference to the remaining figures, the opening of the folder 30 for use of the mobile phone, the folder 30 is formed of the annulus 36 formed at the end of the support shaft 34 thereof. Is rotated upward about the coupling shaft 66 connecting the center of the first and second rotation center body (62, 64). At this time, the rotational core 60, that is, the first and second rotational cores 62 and 64 are coupled to the grooves 72 formed around the outer circumference and the guide protrusions 22 protruding from the accommodation grooves 14 so that the folder ( 30 is not rotated during the opening and closing operation, and even when the folder 30 is rotated in the left and right directions during opening and closing, the recess 72 has the axis of the support shaft 34 at a position where the folder 30 is completely opened. Since it is formed in the direction orthogonal to X), the rotational direction of the folder 30 and the support shaft 34 and the formation direction of the groove 72 are shifted in the intermediate portion where the folder 30 does not reach the fully opened point. Therefore, since the rotation center 60 cannot be rotated, the folder 30 is not rotated from side to side.

Furthermore, since the elastic pressurizer 80 elastically presses the flat portion 70 formed on both sides of the rotational core 60, the opening and closing operation of the folder 30 can be smoothly performed without the left and right shaking of the rotational core 60. Is done.

After using the mobile phone as described above, as an operation to close the liquid crystal display 32 facing outward, it is first checked whether the folder 30 is completely opened.

When the folder 30 is completely opened, the rotation center axis X of the folder 30 and the support shaft 34 and the rotation center axis of the groove 72 and the guide protrusion 22 coincide with each other, as described above. The center body 60 can be rotated (FIG. 7B).

When the folder 30 is rotated to both left and right sides while the folder 30 is completely open as described above, the rotation center 60 is rotated by the support shaft 34 of the folder 30 and its annulus 36. While the rotational core 60 has a flat portion 70 formed on both sides thereof, two jaw portions 74a and 74b are formed on one of the flat portions 70, and the jaw portion 74a is formed. Since one of the 74b contacts the side of one of the elastic presses 80 on both sides to stop the rotation, when the folder 30 is turned to both the left and right sides, it is blocked by the elastic press 80 on one side and the jaw. The rotation is not performed in the direction of rotation, but only in the opposite direction.

Therefore, when the folder 30 is rotated in the rotational direction, the rotation center body 60 rotates by the support shaft of the folder 30. The rotational core 60 has the folder 30 fully open, so that the rotational center axis X of the folder 30 and the rotational center of the groove 72 on the rotational center 60 coincide with each other. Rotation is made while the groove 72 slides the guide protrusion 22. In this case, the elastic pressing body 80 which has pressed the flat portions 70 on both sides of the rotation center body 60 is also retracted by the rotation of the flat portion 70, that is, the plunger 84 compresses the spring 82. While retreating while the rotation center 60 rotates.

Here, when the rotation center 60 is divided into first and second rotation centers 62 and 64, when the rotation center 60 rotates about 90 degrees, the first and second rotation centers ( The gap d between the 62 and 64 and the elastic pressurizer 80, that is, the plunger 84 meet, and the diameter of the plunger 84 of the elastic pressurizer 80 depends on the preferred direction of the present invention. Since the gap d is larger than the gap d, the gap d may be rotated without any difficulty even if the gap d meets the elastic pressurizer 80.

Next, referring to FIG. 7C, when the rotation of the folder 30 and the rotational core 60 exceeds an angle of 180 degrees, among the jaws 74a and 74b formed on the flat portion 70 of the rotational core 60. Before the folder 30 rotates, the jaw portion (that is, the lower jaw portion 74a) that is in contact with the opposite elastic pressing member 80 (the lower elastic pressing member shown by a thin chain line on the drawing) is diagonally first. The jaw portion (that is, the upper jaw portion 74b) is stopped by being caught by the front elastic pressing body 80 (that is, the upper elastic pressing body shown by a thick chain line in the drawing).

As shown in FIG. 7D, when the folder 30 is closed in the above state, the rotation center body 60 is in place as described above, and the support shaft 34 of the folder 30 is the rotation center body 60. It is closed by rotating downward about the coupling shaft 66. As a result, the LCD screen 32 is exposed to the outside of the folder 30.

As described above, when the liquid crystal display 32 is exposed and used to be inward, the folder 30 is opened and maintained in the same state as in FIG. 7, and then rotated from FIG. 7B to FIG. 7C. As described, when the folder 30 is turned to both sides, it is rotated on one side by the locking action of the jaws 74a, 74b and the elastic pressurizer 80 of the rotation center 60, and the rotation is not performed on the opposite side. Do not.

The rotation is made in the opposite direction to the direction in which the rotation was made in the state of Fig. 7B to Fig. 7C, that is, the liquid crystal display 32 is turned inward while facing inward. As a result, when rotating the center of rotation 60 in the rotational direction in the state of Figure 7c, the lower jaw portion (74b) is rotated downward away from the elastic pressing body (80, shown in a thick chain) When the upper jaw portion 74a is also rotated downward, and the rotation is about 180 degrees, the upper jaw portion 74a is caught by the elastic pressing body 80 (shown by a thin chain circle) on the opposite side and stopped. do. When the folder 30 is closed in this state, the LCD screen 32 is positioned inside the folder 30 as shown in FIG. 7A.
