Referring to FIG. 3, the fixing part 40 may be formed as an adsorption plate to which the mobile device M may be adsorbed and attached. The adsorption plate has a structure that can be attached to an object having a smooth surface using vacuum pressure. Most mobile devices (M) have a smooth smooth surface, can be easily fixed by the suction plate.

However, the adsorption plate is only a preferred embodiment of the fixing part 40, and the fixing part 40 is a fixing plate including an adhesive component, a magnetic plate using magnets, an uneven part having an uneven structure, or various fixing means such as a clamp type. This is possible.

On the other hand, the fixing part 40 is coupled to the body 10 by the rotation shaft 41 so as to be rotatable. That is, the mobile device M coupled to the fixing part 40 is fixed to the body 10 so as to be rotatable, and the mobile device M may be attached to the joy pad 1 regardless of the vertical direction or the horizontal direction. have.

The body 10 is formed thinner than the first handle 20 and the second handle 30 so that the mobile device M can be inserted between the first handle 20 and the second handle 30. Can be.

Hereinafter, a process of shortening or extending the joy pad 1 by inserting or ejecting the first handle 20 and the second handle 30 into the body 10 will be described in detail with reference to FIGS. 4 and 5.

FIG. 4 is a cross-sectional plan view of a portion of the joy pad of FIG. 1 shortened, and FIG. 5 is a cross-sectional view of a portion of the joy pad of FIG. 1 extended.

First, referring to FIG. 4, when the mobile device M is used in the vertical direction, one end of the first handle 20 and the second handle 30 are inserted into the body 10, and the joy pad 1 is used. The length of is shortened. That is, the space between the first handle 20 and the second handle 30 is left, leaving only enough space for the mobile device M to be inserted between the first handle 20 and the second handle 30 to be inserted. Will be reduced.

The first handle 20 includes a first extension 21 extending toward the body 10, and the first gear bar 22 is coupled to one side of the first handle 20. When the joy pad 1 is extended, the first extension part 21 extends outside the body 10 to connect the first handle 20 and the body 10.

The first extension part 21 is in close contact with the inner surface of the body 10, and when the first handle 20 moves away from the body 10, the first extension part 21 slides and is discharged from the body 10.

On the other hand, the second handle 30 includes a second extension portion 31 extending toward the body 10, the second gear bar 32 is coupled to one side of the second handle (30). When the joy pad 1 is extended, the second extension part 31 extends outside the body 10 to connect between the second handle 30 and the body 10.

The second extension part 31 slides in the same manner as the first extension part 21 and is discharged from the body 10.

The first handle 20 and the second handle 30 may be formed to be substantially symmetrical to each other except for the arrangement of the direction key 25 or the button 35.

In the central portion of the body 10 into which the first handle 20 and the second handle 30 are inserted, respectively, a rotation gear 42 having a fixed portion (see 40 in FIG. 1) is formed. The rotation gear 42 is connected to the fixed part 40 by the rotation shaft (refer 41 of FIG. 3), and is connected to the fixed part 40 to coaxially rotate. That is, the fixing part 40 also rotates with the rotation angle of the rotation gear 42.

Meanwhile, the first gear bar 22 and the second gear bar 32 are coupled to one side of the first handle 20 and the second handle 30, respectively. The first gear bar 22 and the second gear bar 32 are engaged with the rotation gear 42 through the first extension part 21 and the second extension part 31, respectively.

The first gear bar 22 and the second gear bar 32 are gear teeth formed in one direction on one side of a bar shape, and may be represented as a rack gear or a rack bar. The rotation gear 42 meshed with the first gear bar 22 and the second gear bar 32 may be a pinion gear coupled with the rack gear. That is, by using the rack and pinion gear, the linear motion of the first gear bar 22 and the second gear bar 32 is converted into a rotational motion for rotating the fixing part 40, or vice versa The rotational motion of can be converted into linear motions of the first gear bar 22 and the second gear bar 32.

The first gear bar 22 and the second gear bar 32 are engaged with the rotation gear 42 with the rotation gear 42 interposed therebetween. Therefore, when the rotation gear 42 rotates, the first gear bar 22 and the second gear bar 32 make linear movements at the same time. At this time, the gear ratios of the first gear bar 22 and the second gear bar 32 are matched to be equal to each other, so that when the rotating gear 42 rotates, the first gear bar 22 and the second gear bar 32 are rotated. ) Can be adjusted so that the moving distance is the same.

Meanwhile, the driving gear 50 may be coupled to at least one of the first gear bar 22, the second gear bar 32, and the rotation gear 42. The drive gear 50 may transmit a driving force to at least one of the first gear bar 22, the second gear bar 32, and the rotation gear 42, and may be driven by the rotational force of the drive gear 50. 20 and the second handle 30 extends from side to side, and the rotation gear 42 rotates the fixing part 40.

The drive gear 50 may receive a driving force by a separate servo motor (not shown) to drive the first gear bar 22, the second gear bar 32, and the rotation gear 42. The drive gear 50 is in the form of a pinion gear, which may be coupled to either the first gear bar 22 or the second gear bar 32, or may be directly engaged with the rotation gear 42.

When the servo motor drives the drive gear 50, the first handle 20 and the second handle 30 are automatically extended, and the mobile device M is also automatically rotated.

On the other hand, when the first gear bar 22 and the second gear bar 32 and the second gear bar 32 and the second gear bar 32, respectively, the maximum parallel movement of the first gear bar 22 and the second gear bar 32, The rotation gear 42 may be formed with a gear ratio to rotate 90 degrees. As such, when the gear ratio is adjusted, when the first handle 20 and the second handle 30 are inserted into the body 10 as much as possible, the mobile device M forms a vertical direction, and the first handle 20. When the second handle 30 extends to the outside of the body 10 as much as possible, the mobile device M may have a horizontal direction. The rotation of the first handle 20 and the second handle 30 and the mobile device M will be described in detail later.

Referring to FIG. 5, the first handle 20 and the second handle 30 extend outward of the body 10, so that the first handle 20 and the second handle even when the mobile device M is switched in the horizontal direction. It may be arranged between (30).

6A to 6C, the use state of the joypad 1 for a mobile device according to the first embodiment of the present invention will be described in detail.

6A through 6C are plan views illustrating a process of changing a direction of a mobile device mounted on the joypad of FIG. 1.

First, referring to FIG. 6A, when an application for a mobile device is optimized for a vertical screen, the mobile device M may be used in a vertical direction. At this time, the joy pad 1 is in a state in which the first handle 20 and the second handle 30 are shortened to each other. That is, the first extension part 21 of the first handle 20 and the second extension part 31 of the second handle 30 are respectively completely inserted into the body 10, and the mobile device M The first handle 20 and the second handle 30 are in close contact with both sides of the).

Subsequently, referring to FIG. 6B, the display device may rotate the mobile device M in the horizontal direction to drive an application optimized in the horizontal direction. In this case, the method of switching the mobile device M from the vertical direction to the horizontal direction may be converted manually or automatically. Referring to the process of automatic conversion, the user drives the servo motor (not shown) to rotate the drive gear (50). The drive gear 50 is meshed with the second gear bar 32, so that the rotational movement of the drive gear 50 is converted to the linear motion of the second gear bar 32. That is, when the drive gear 50 pushes the second gear bar 32 out of the body 10, the second gear bar 32 extends the second handle 30 to the outside and at the same time rotates the rotation gear ( Rotate 42).

The rotation gear 42 is connected to the first gear bar 22 and the second gear bar 32 at the same time. When the rotation gear 42 rotates, the first gear bar 22 is the second gear bar 32. Moves in the opposite direction to the second gear bar 32 by the distance traveled. Accordingly, when the drive gear 50 rotates, the first gear bar 22 and the second gear bar 32 push the first handle 20 and the second handle 30 to the outside of the body 10. , The rotation gear 42 is also rotated with the mobile device (M) by the rotational force.

On the other hand, the extending process of the first handle 20 and the second handle 30 is also possible manually. In detail, in the case of the joy pad 1 having no driving gear, the first handle 20 and the second handle 30 are held by hands, and pulled in opposite directions. At this time, the first handle 20 and the second handle 30 are each slide from the body 10 to extend out of the body 10, at the same time the mobile device (M) is rotated in the horizontal direction.

Subsequently, referring to FIG. 6C, the first handle 20 and the second handle 30 extend completely out of the body 10, and the mobile device M is rotated by 90 degrees and disposed in the horizontal direction. As described above, when the first handle 20 and the second handle 30 are fully extended outward by adjusting the gear ratio of the first handle 20, the second handle 30, and the rotation gear 42, the rotation is performed. The gear 42 can be rotated by 90 degrees.

The body 10, the first extension part 21, and the second extension part 31 are disposed between the first handle 20 and the second handle 30, and the mobile device M is disposed therein in the horizontal direction. Is placed. As described above, the display direction of the mobile device M can be easily switched by automatically or manually operating the first handle 20 and the second handle 30.

Hereinafter, a joypad for a mobile device according to a second embodiment of the present invention will be described in detail with reference to FIGS. 7 to 9B.

7 is a perspective view of a joy pad for a mobile device according to a second embodiment of the present invention, FIG. 8 is a cross-sectional view taken along line AA ′ of the joy pad of FIG. 7, and FIGS. 9A to 9B are included in the joy pad of FIG. 7. Partial perspective view showing the operation of the locking portion.

First, referring to FIG. 7 and FIG. 8, the joy pad 1 according to the second embodiment of the present invention fixes the mobile device M using the fixing plate 60 and the fixing clip 61, and the mobile device ( Connector 62 in communication with M).

Specifically, the structure for fixing the mobile device (M) using the fixing plate 60 and the fixing clip 61 can be easily and simply fixed to the mobile device (M). The fixed plate 60 forms a seating surface on which the mobile device M is seated, and is coupled to the rotary shaft 41 connected to the rotation gear 42. Thus, the fixed plate 60 rotates together on the same axis as the rotation gear 42 rotates, as described above.

The fixing plate 60 is formed in a rectangular shape like the shape of the mobile device M, and fixing clips 61 are formed at both ends of the fixing plate 60. The fixed clip 61 has elasticity, and when the mobile device M is inserted between the fixed clips 61, the fixed clip 61 is fixed to the fixed plate 60 so that the mobile device M does not move. The fixing plate 60 and the fixing clip 61 may be integrally formed using a material having elastic force. The position of the fixing clip 61 may be disposed in the horizontal direction or the vertical direction of the mobile device (M).

The fixed clip 61 may be refracted to the inside where the mobile device (M) is located, using a wide elastic range material to fix the mobile device (M) of various sizes and shapes, or the fixed clip (61) In addition to the elastic force of the fixing plate 60 and the additional elastic member can be used. For example, by combining a separate elastic pad (not shown) between the fixing clip 61 and the mobile device (M), it is possible to widen the range of mobile devices (M) available.

On the other hand, one side of the fixing plate 60 may be provided with a connector 62 for connecting the mobile device (M) and the joy pad (1). The connector 62 serves as an interface between the mobile device M and the joy pad 1, and may transmit a control signal of the joy pad 1 to the mobile device M.

The connector 62 may not only transmit a control signal of the joy pad 1, but also serve to supply power to the mobile device M. For example, when the mobile device M is discharged, the mobile device M is driven by using a power supply inside the joy pad 1 or an adapter power connected to the joy pad 1, and simultaneously charged to the mobile device M. You can also do

In addition, the connector 62 may transmit a sound signal of the mobile device M to the joy pad 1. The joy pad 1 may include a speaker (not shown) by itself, and may amplify the sound of the mobile device M to assist the user to enjoy a realistic game.

However, the connector 62 coupled to the fixing plate 60 is merely an example, and is not necessarily limited to the connector to be mechanically connected. For example, when the mobile device M supports a wireless protocol such as Bluetooth, communication between the mobile device M and the joy pad 1 may be performed using Bluetooth. Therefore, it is possible to transmit and receive a control signal or to transmit and receive a sound signal even without connecting to a separate connector.

Meanwhile, the joy pad 1 may further include a locking part 70 to limit the slide movement of the first handle 20 and the second handle 30 and the rotational movement of the fixing plate 60. The lock part 70 is coupled to at least one of the first gear bar 22, the second gear bar 32, and the rotation gear 42, so that the first gear bar 22 and the second gear bar 32 are connected to each other. It may limit the linear movement, or limit the rotational movement of the rotary gear 42. In the present embodiment, the locking portion 70 meshed with the first gear portion 71 and the first gear portion 71 restricts linear movement will be described as an example.

The lock part 70 includes a gear part 71 meshed with the first gear bar 22, and an elastic member applying elastic force to the gear part 71 to engage the first gear bar 22 and the gear part 71. And 72.

8 and 9A, the gear part 71 is meshed with the first gear bar 22. The first gear bar 22 may move in the horizontal direction, but the gear portion 71 may move in the vertical direction. Therefore, when the gear part 71 is meshed with the 1st gear bar 22, the 1st gear bar 22 will not be able to move to a horizontal direction.

The gear portion 71 is connected to the push button 73 protruding outward of the body 10 on one side, and the other side is coupled to the elastic member 72. The gear part 71 is movable only in the direction in which the elastic member 72 is coupled while being engaged with the first gear bar 22. However, the elastic member 72 applies elasticity to the gear portion 71 so that the gear portion 71 can always be engaged with the first gear bar 22. However, when the pressure is applied to the push button 73, the gear portion 71 is separated from the first gear portion 71 while contracting the elastic member (72). That is, when pressure is applied to the push button 73, the gear unit 71 and the first gear bar 22 are released, and when the pressure is released, the gear unit 71 and the first gear bar 22 are again released. It is a structure to be engaged. The elastic member 72 may be in various forms capable of storing and transmitting elastic forces such as coil springs, leaf springs, and rubber.

Referring to FIG. 9B, while the pressure is applied to the push button 73 and the gear unit 71 is separated from the first gear bar 22, the first gear bar 22 may move in the horizontal direction. That is, the first gear bar 22 is movable only in the horizontal direction, and cannot move in the vertical direction. On the other hand, the gear portion 71 has a function of moving only in the vertical direction, and cannot move in the horizontal direction. Accordingly, the gear part 71 may move in the vertical direction irrespective of the first gear bar 22, but the first gear bar 22 may move in the horizontal direction unless the gear part 71 is engaged with the gear part 71. impossible.

When pressure is applied to the push button 73 and the gear unit 71 is separated from the first gear bar 22, the first gear bar 22 may move in the horizontal direction.

As described above, the locking unit 70 is merely an example, and means for fixing any one of the first gear unit 71, the second gear unit 71, and the rotation gear 42 may be variously modified. Could be.

Hereinafter, a joypad for a mobile device according to a third embodiment of the present invention will be described in detail with reference to FIGS. 10 and 11.

FIG. 10 is a front view of a joy pad for a mobile device according to a third embodiment of the present invention, and FIG. 11 is a front view showing a shortened view of the joy pad for a mobile device of FIG.

The joy pad 1b for a mobile device according to the third embodiment of the present invention includes a first detection button 26L and a second detection button that can be pressed by the index finger on the first handle 20b and the second handle 30b. 26R), the mobile device (M) can be moved upward at the same time as the rotation.

First, referring to FIG. 10, the first handle 20b and the second handle 30b extend left and right, and the mobile device M may be disposed in a horizontal direction. When the mobile device M is disposed in the horizontal direction, the mobile device M may be disposed inside the joy pad 1b to substantially integrate.

The first handle 20b includes a first detection button 26L operable with the left index finger, and the second handle 30b includes a second detection button 26R operable with the right index finger. have. The manner in which the mobile device M is gripped by the joy pad 1b is as described above, and a separate description thereof will be omitted.

The first detection button 26L and the second detection button 26R allow the joy pad 1b to be manipulated using various fingers, thereby enabling the game user to control various operations easily and easily. The first detection button 26L and the second detection button 26R are formed in a structure of pressing the direction keys 25 and the button 35 in a vertical direction on one side of the first handle 20b and the second handle 30b. Can be.

Subsequently, referring to FIG. 11, the first handle 20b and the second handle 30b are shortened in the center direction to rotate the mobile device M in the vertical direction. In this case, the mobile device M may not coincide with the center portion of the joy pad 1b. That is, the center of the mobile device M may move upwards than the center of the joy pad 1b. Therefore, the lower end of the mobile device M coincides with the lower end of the joy pad 1b, so that the viewing angle of the mobile device M may be improved.

Due to the structure of the human body, the position of the hand is lower than the position of the visual field, and the structure in which the mobile device M, which becomes the display screen, protrudes upward from the joy pad 1b is arranged to allow the game user to enjoy the game comfortably.

Hereinafter, a joypad for a mobile device according to a fourth embodiment of the present invention will be described in detail with reference to FIGS. 12 and 13.

FIG. 12 is a front view of a joy pad for a mobile device according to a fourth embodiment of the present invention, and FIG. 13 is a front view showing how the fixing plate of the joy pad for a mobile device of FIG. 12 is rotated.

The joy pad 1c for a mobile device according to the fourth embodiment of the present invention includes a first detection button 26L and a second detection button 26R that can be pressed by an index finger, and a direction key 25 and a button 35. ) Is disposed on the body (10c) located in the lower portion of the mobile device (M).

It may not be desired to change the distance between the direction key 25 and the button 35 according to the taste of the game user. In this case, the direction key 25 and the button 35 are formed in the body 10c, so that the constant distance is always maintained regardless of the direction of the mobile device (M).

The body 10c is integrally formed, the direction key 25 and the button 35 are formed on the front surface, and the first detection button 26L and the second detection button 26R are formed on the side surface.

On the other hand, the mobile device (M) is formed to be biased upward so as not to overlap the direction key 25 and the button 35 on the front of the body (10c). Therefore, the display screen is positioned above the direction key 25 and the button 35. Since the gripping structure of the mobile device M is substantially the same as the above-described embodiment, a detailed description thereof will be omitted.

Subsequently, referring to FIG. 13, the mobile device M is rotated in the vertical direction, and a game is possible. When the mobile device M is rotated in the vertical direction, the first detection button 26L and the second detection button 26R formed on the body 10c are exposed, so that the game user can enjoy the game more freely. At this time, the mobile device (M) is rotated in the vertical direction at the same time moving in the upper direction, the mobile device (M) does not cover the direction key 25 or button 35.
