Description

Description TILTABLE SLIDING DEVICE

Technical Field

[1] The present invention relates to a sliding device; and, more particularly, to a sliding device that can realize diverse modes by being slid and tilt. Background Art

[2] Personal mobile terminals are generally divided into flip type, folder type, and sliding type ones.

[3] Among them, personal mobile terminals of the sliding type include a main unit and a cover unit sliding over the main unit. The sliding motion between the main unit and the cover unit is performed by a sliding module.

[4] The sliding module includes a base connected to the main unit and a sliding member connected to the cover unit to be capable of sliding over the base. The sliding module includes a coil spring between the base and the sliding member to give elasticity to the sliding motion between the base and the sliding member.

[5] Since conventional sliding-type personal mobile terminals simply slides in one direction, they have a limitation in keeping up with the industrial trends of adding diverse functions to personal mobile terminals. Disclosure of Invention Technical Problem

[6] An embodiment of the present invention devised to overcome the problems of conventional technology is directed to providing a sliding devise that can realize diverse modes for convenient use.

[7] Another embodiment of the present invention is directed to providing a sliding device that can have a tilt as well as sliding motion to thereby effectively realize diverse functions when it is applied to personal mobile terminals. Technical Solution

[8] In accordance with an aspect of the present invention, there is provided a tiltable sliding device, which includes: a cover unit; a main unit disposed behind the cover unit; a sliding module having a plurality of members sliding between the cover unit and the main unit and combined with the cover unit on a first side; and a tilting module combined with a second side of the sliding module and capable of tilting at a predetermined angle to the main unit.

[9] The sliding module may slide in a first direction and a second direction crossing the first direction. The sliding module may include: a base with first guide elements in the first direction; a first sliding member both ends of which are housed by the first guide elements to make a sliding move over the base in the first direction and including second guide elements formed in the second direction; and a second sliding member both ends of which are housed by the second guide elements and sliding over the first sliding member in the second direction.

[10] The tilting module may be capable of tilting when the sliding module is slid in the first or second direction. The tilting module may include: a tilting member combined with the second side of the sliding module and tilting at a predetermined angle; and a driver disposed on a rotary axis of the tilting member and applying rotary force to the tilting member.

[11] The driver may apply a different rotary force to the tilting member according to a rotation angle of the tilting member. The driver may have a threshold point within a maximum rotation angle, and the driver does not apply rotary force to the tilting member at the threshold point.

[12] The driver may include: a sliding cam having a plurality of first gears; a rotary cam having a plurality of second gears corresponding to the first gear for engagement; and a contacting member for contacting the sliding cam and the rotary cam with elasticity.

[13] The tilting module may include: a tilting member combined with the second side of the sliding module and tilting at a predetermined angle; and a link member one side of which is combined with the main unit to be rotatable and the other side is combined with a side of the tilting member to be rotatable. The tilting module may further include: a driver disposed on a rotary axis of the main unit and the link member and applying rotary force to the link member.

[14] The tilting module may include a guide protrusion protruded outwardly on one side, and the main unit includes a guide groove for guiding a moving direction of the guide protrusion.

[15] The tilting module may further include: a rotation interrupter for optionally stopping rotation of the tilting member by a one-directional motion of the sliding module.

[16] The rotation interrupter may include: an anchor having a rotary wing engaged with the protrusion formed on a rear surface of the sliding module and making a rotation, and a rotary protrusion rotating along with the rotary wing; and an interruption plate having a rotary protrusion housing groove to be engaged with the rotary protrusion and making a translational motion in one direction upon rotation of the rotary protrusion so that one side of the interruption plate is optionally engaged with an interruption groove formed in the main unit.

[17] The anchor is formed to make the interruption plate get out of the interruption groove by the rotation of the rotary protrusion, when the sliding module slides in one direction.

[18] The anchor further may include a rotary cam with a pair of mode grooves cor- responding to an rotation interruption mode for stopping rotation of the tilting member and an interruption release mode for making the tilting member rotate, respectively; and the rotation interrupter further includes a fixing protrusion giving elasticity toward a mode groove and optionally engaged with the mode groove. The rotary cam may be formed between the rotary wing and the rotary protrusion.

Advantageous Effects

[19] The sliding device of the present invention having the above structure has the following advantageous effects.

[20] First, the sliding device can realize diverse modes between a main unit and a cover unit as it includes a sliding module for implementing sliding operation and a tilting module for implementing a tilting operation.

[21] Particularly, it can realize a tilting mode for the convenience of a user as it includes a driver for applying rotation force to the tilting module. Also, the driver is formed to have a threshold point within the maximum tilting angle, which makes the cover unit smoothly operate a tilting operation or an operation opposite to the tilting operation.

[22] The sliding device can make the cover unit move to the rear part while implementing the tilting operation to thereby efficiently secure a space for an input unit of the main unit as it is formed to perform the tilting operation by instrumental operation between a plurality of members.

[23] Secondly, the sliding device of the present invention can realize diverse modes as it includes a first sliding member and a second sliding member moving in directions crossing each other to thereby vary sliding direction.

[24] Since sliding motion in one direction binds the sliding motion in the other direction among first and second sliding directions, the sliding operation can be implemented stably and comfortableness on the part of a user is improved.

[25] Also, since the sliding can be performed in crossing directions, it is possible to provide space for new input buttons to the body of a personal mobile terminal connected to the sliding module. Thus, new functions may be provided to the personal mobile terminal and the body of the personal mobile terminal can be transformed to be suitable for a game mode or a general phone mode.

[26] Thirdly, the sliding device can perform sliding operation smoothly without interference between members as the tilting module includes a rotation interrupter for optionally keeping a tilting member away from rotating during general vertical-directional sliding operation of the sliding module.

[27] Particularly, the sliding device makes it possible to interrupt rotation of the tilting member and release the rotation interruption through simple instrumental operation by forming the rotation interrupter of an anchor and an interruption plate. Brief Description of the Drawings

Best Mode for Carrying Out the Invention [49] The advantages, features and aspects of the invention will become apparent from the following description of specific embodiments with reference to the accompanying drawings, which is set forth hereinafter. The same name and reference numerals are given to the same constituent elements although they appear in different drawings.

[50]

[51] 1ST EMBODIMENT

[52] A sliding device of the present invention largely includes a cover unit, a main unit, a sliding module, and a tilting module. Referring to Figs. 1 and 2, the sliding module of the sliding device will be described hereafter. Fig. 1 is a perspective view of a sliding module in accordance with the first embodiment of the present invention, and Fig. 2 is an exploded perspective view of the sliding module shown in Fig. 1.

[53] The sliding module 10 includes a base 100, a first sliding member 200 connected to the base 100 to be capable of sliding thereon, and a second sliding member 300 connected to the first sliding member 200 to be capable of sliding thereon. The first sliding member 200 and the second sliding member 300 are formed to have a sliding direction crossing each other.

[54] The base 100 includes first guide elements 110 and 120. In the present embodiment, the first guide elements 110 and 120 are formed on both confronting sides of the plate- shaped base 300.

[55] As shown in Figs. 2 and 3, the first guide elements 110 and 120 are formed to have a shape of an English letter 'C as both ends of the base 100 are bent up.

[56] In this embodiment, the first guide elements 110 and 120 are provided with first guide molds 130 and 140, which are formed of a lubricant material. The first guide molds 130 and 140 prevent the generation of excessive frictional force when the first sliding member 200 slides along the first guide elements 110 and 120. The first guide molds 130 and 140 can also prevent the generation of noise and deterioration in the sense of sliding that may be caused by the frictional force as well as helping smooth sliding motion.

[57] There is no limitation in the material for the first guide molds 130 and 140 as long as the material has a lubricating property. For example, engineering plastics (EPs) such as polyacetal (POM), polyphenylene oxide (PPO), polycarbonate (PC), and polybutylene terephthalate (PBT) may be used.

[58] Meanwhile, the base 100 includes a plurality of joining holes 150 so that the base

100 is combined with a tilting module 20.

[59] The first sliding member 200 slides in a first direction over the base 100 with its both sides housed by the first guide elements 110 and 120.

[60] To be specific, a protrusion 240 is formed in a second direction, which is y direction, along the upper and lower parts of the first sliding member 200. The protrusion 240 is housed by the first guide elements 110 and 120.

[61] Meanwhile, the first slide member 200 includes second guide elements 210 formed in the second direction across the first direction. [62] In this embodiment, the first direction and the second direction are crossing each other, specifically, the first direction is designated as x direction and the second direction is y direction perpendicular to the x direction. [63] The second guide elements 210 are formed on both confronting sides of the first sliding member 200 in the y direction. Alike the first guide elements 110 and 120, the second guide elements 210 have a shape of English letter 'C as both ends of the first sliding member 200 are bent up. [64] As shown in Fig. 1, the second guide elements 210 are disposed in a space between the first guide elements 110 and 120 to make a sliding motion between the first guide elements 110 and 120. [65] The second guide elements 210 are also provided inside with second guide molds

230 formed of a lubricant material to prevent generation of excessive frictional force. [66] Meanwhile, an opening 260 is formed in the central part of the first sliding member

200 in the first and second directions to provide a space for a flexible printed circuits board (FPCB) to penetrate for electrical connection when the sliding module 10 is combined with a main unit 40 and a cover unit 30. [67] The second sliding member 300 is formed to slide over the first sliding member 200 in the second direction, which is the y direction, with its sides housed by the second guide elements 210. [68] To be specific, the second sliding member 300 includes bent elements 310, which are bent twice downward, on both sides. The bent elements 310 are housed by the second guide elements 210 so that the second sliding member 300 slides in the second direction. [69] Meanwhile, the second sliding member 300 includes a plurality of joining holes 350 for combining the second sliding member 300 with the cover unit 30 (see Fig. 7) later. [70] The specific shapes of the base 100, the first sliding member 200 and the second sliding member 300 may be changed diversely according to the design conditions of a product to which the sliding module 10 is applied. [71] Although not shown in the drawings, an elastic member may be provided between the base 100 and the first sliding member 200 and between the first sliding member

200 and the second sliding member 300 to make the sliding motion between the members elastic. Specific shape and position of the elastic member may be changed diversely according to design conditions. [72] Meanwhile, the first guide element 120, which is disposed in the upper part of the first guide element 110, includes a path provider 125 to provide a path for the second sliding member 300 to move in the second direction. [73] To sum up, the first guide elements 110 and 120 are bent up to thereby prevent the second sliding member 300 from moving in the y direction, but the path provider 125 disposed in the first guide element 120, which is the upper one, allows the second sliding member 300 to move in the y direction, when the second sliding member 300 is positioned at a specific spot in the x direction.

[74] Meanwhile, the path provider 125 is formed in the shape of an inwardly subsided gr oove as illustrated in Figs. 2 and 3. The path provider 125 is designed to stop the first sliding member 200 from moving over the base 100 when the second sliding member 300 makes a move in the y direction.

[75] The first guide mold 140 is inserted into the first guide element 120, which is an upper element. The first guide mold 140 has a mold groove 145 at a position corresponding to the path provider 125 in a shape corresponding to the path provider 125.

[76] Meanwhile, according to the present embodiment, stopper 170, 270 and 370 are provided between the base 100 and the first sliding member 200 and between the first sliding member 200 and the second sliding member 300 to confine the sliding motion within a predetermined range.

[77] To be specific, a first stopper 170 is formed to be bent up from the base 100. When the first sliding member 200 slides more than a predetermined distance in the first direction, the end of the opening 260 of the first sliding member 200 hits the first stopper 170 and does not move any more.

[78] A second stopper 270 is formed to be bent up from the first sliding member 200, and a third stopper 370 is formed to be bent down from the second sliding member 300. The second and third stoppers 270 and 370 hold the second sliding member 300, when the second sliding member 300 moves down by more than a predetermined distance in the second direction.

[79] Accordingly, although the second sliding member 300 slides in the first direction, the second sliding member 300 is kept away from contacting the first guide elements 110 and 120 of the base 100 and causing any friction between the second sliding member 300 and the first guide elements 110 and 120.

[80] In addition, a separation prevention element 320 is formed on both sides of the second sliding member 300 to be bent down. When the second sliding member 300 moves toward the x direction, the first guide elements 110 and 120 bind up the separation prevention element 320 to thereby interrupt the second sliding member 300 from moving in the y direction.

[81] Referring to Figs. 3 and 4, sliding operation of the sliding module will be described hereafter. Fig. 3 is a perspective view describing how the sliding module of Fig. 1 slides out in a second direction, and Fig. 4 is a perspective view describing how the sliding module of Fig. 1 slides out in a first direction.

[82] First, a process that the sliding module 10 slides in the second direction, which is the y direction, will be described hereafter in accordance with the present invention.

[83] In the initial state, the second sliding member 300 is placed at a position where it can be slid out in the y direction through the path provider 125. When force is applied to the second sliding member 300 in the y direction, the bent elements 310 on the left part of the second sliding member 300 make a move in the y direction through the second guide elements 210 and the path provider 125, which is illustrated in Fig. 3.

[84] When the second sliding member 300 moves in the y direction, the bent elements

310 of the second sliding member 300 cannot move in the x direction but it can move only in the y direction due to the groove-shaped path provider 125.

[85] Therefore, it is possible to prevent the sliding module 10 from moving in the x direction while it makes a sliding move in the y direction in this embodiment.

[86] Subsequently, a process that the sliding module 10 slides in the first direction, which is the x direction, will be described hereinafter.

[87] In the initial state, the second sliding member 300 can select whether to move in the x direction or in the y direction. However, once force is applied toward the x direction, as shown in Fig. 4, the first sliding member 200 and the second sliding member 300 come to move in the x direction together.

[88] The move toward the x direction is performed with the protrusions 240 formed in the upper and lower parts of the first sliding member 200 accommodated by the first guide elements 110 and 120 of the base. As illustrated in Fig. 4, once the first sliding member 200 and the second sliding member 300 move in the x direction, the y- directional move of the second sliding member 300 is bound by the first guide elements 110 and 120 formed in the upper part of the base 100.

[89] Particularly, since the separation prevention element 320 is formed in the second sliding member 300 to have a shape bent downward, the y-directional move of the second sliding member 300 is bound by the first guide elements 110 and 120.

[90] In other words, the second sliding member 300 can make a move in the y direction only in the initial state along the path provider 125 and, once it makes a move in the x direction, the separation prevention element 320 holds the second sliding member 300 from moving in the y direction.

[91] Therefore, the sliding module 10 of the present embodiment is kept away from moving in the y direction when it is sliding in the x direction.

[92] Referring to Figs. 5 to 8, the structures and connection of the sliding module and the tilting module, which constitute the sliding device of the present invention will be described hereafter. Fig. 5 is an exploded perspective view of the sliding module shown in Fig. 1 and a tilting module, and Fig. 6 is a perspective view showing the sliding module and the tilting module shown in Fig. 5 when they are combined. Fig. 7 is an exploded perspective view showing a driver of the tilting module, and Fig. 8 is a perspective view illustrating a sliding device at tilt in accordance with the first embodiment of the present invention. [93] As illustrated in Fig. 5, the upper side of the second sliding member 300 is combined with a cover unit in above-described sliding module 10, while the lower side of the base 100 is combined with the tilting module 20. [94] The tilting module 20 is combined with the base 100 of the sliding module 10 in such a manner that the tilting module 20 has a tilt at a predetermined angle against the main unit 40. [95] To be specific, the tilting module 20 of this embodiment includes a tilting member 25 combined with the base 100 and tilting at a predetermined angle, and a driver 400 mounted on a rotary axis of the tilting member 25 and giving a rotation force to the tilting member 25. [96] The tilting member 25 includes a housing groove 22 for accommodating part of the sliding module 10. On the contrary, a connection groove 24 is formed on the rotary axis of the tilting member 25 to accommodate a connection member for connection with the main unit 40. [97] Meanwhile, as illustrated in Figs. 5 and 6, a driver joining hole 26 is formed on an external side of a rotary axis of the tilting member 25 in a non-circular shape to be engaged in with a side of the driver 400. [98] The driver 400 is a constituent element for applying a rotation force to the tilting member 25 and it can be formed in diverse shapes. [99] Fig. 7 illustrates an example of the driver 400, which basically includes a sliding cam

430, a rotary cam 420, and contacting member 440. [100] The rotary cam 420 includes a plurality of first gears, and the sliding cam 430 includes a plurality of second gears corresponding to the first gears so that the second gears are engaged in with the first gears of rotary cam 420. [101] The contacting member 440 has a form of a spring obtained by winding coil and it contacts the sliding cam 430 and the rotary cam 420 to each other. [102] Meanwhile, the sliding cam 430, the rotary cam 420 and the contacting member 440 are accommodated inside a housing 410 with a shaft 450 penetrating at the center. The shaft 450 is fixed by a washer 462 and a fixing member 464 at one end of the housing

410. [103] In the driver 400 formed as above, the elasticity of the contacting member 440 in the longitudinal direction tightly contact the sliding cam 430 and rotary cam 420 to each other. Thus, slipping occurs in the slope between the sliding cam 430 and the rotary cam 420 to thereby produce rotation force. The rotation force rotates the tilting member 25. [104] Meanwhile, the driver 400 has a threshold point within the maximum rotation angle of the tilting member 25. [105] Herein, the threshold point is where the highest sides of the sliding cam 430 and the rotary cam 420 meet with each other. When the tilting member 25 is at the threshold point and a user applies a little force upward or downward, the elasticity of the contacting member 440 lays the tilting member 25 or stands it up right. [106] The present embodiment is designed to place the threshold point within the tilting angle range. However, it is also possible to change the disposition of the sliding cam

430 and the rotary cam 420 and make the driver 400 apply rotation force in a direction that the tilting member 25 tilts. [107] When the driver 400 is formed to continuously apply rotation force in the tilted direction, the cover unit 30 is operated to be tilt automatically while it is sliding in the x direction. [108] Fig. 8 illustrates the sliding module 10 with the cover unit 30 on one side and the tilting module 20 on the other side. The tilting module 20 has a tilt over the main unit

40. [109] Although not illustrated in Fig. 8, the tilting member 25 may have a stopper on the rotary axis of the tilting member 25 to stop rotating more than a predetermined angle. [110] The driver 400 is formed buried in the main unit 40, and one side of the driver 400 is engaged with the driver connection hole 26 of the tilting member 25. [I l l] Meanwhile, since the rotary axis of the tilting member 25 is positioned at the center, tilting does not occur until the cover unit 30 slides. The tilting member 25 can make a tilt only when the cover unit 30 completely slides out in the x direction. [112] The main unit 40 includes an internal groove 42 on the upper surface to accommodate the sliding module 10 and the tilting module 20 when they do not make a tilt. [113]

[114] 2ND EMBODIMENT [115] Referring to Figs. 9 to 12, a sliding device will be described in accordance with a second embodiment of the present invention. [116] Similarly to the sliding device of the first embodiment, the sliding device of the second embodiment, too, basically includes a cover unit 60, a main unit 70, a sliding module 10, and a tilting module 50. The sliding module 10 is formed capable of sliding optionally in a first direction and a second direction. [117] Differently from the first embodiment, however, the tilting operation of the tilting module 50 is performed by instrumental operation between a tilting member 510 and a link member 520. [118] To be specific, as illustrated in Fig. 9, the tilting member 510 is combined with a base 100 of the sliding module 10, and the tilting member 510 includes a housing groove 512 in the center to accommodate a part of the sliding module 10.

[119] The tilting member 510 additionally includes a connection protrusion 516 formed outwardly on a side to be combined with the link member 520.

[120] The link member 520 includes a connection groove 522 on one side to be rotatably engaged with the connection protrusion 516 of the tilting member 510. Thus, the link member 520 can perform counter-rotation operation to the tilting member 510.

[121] Also, the other side of the link member 520 is rotatably engaged with the main unit 70, and a driver connection hole 524 is formed in a non-circular shape on the external side to be engaged with a side of the driver 400.

[122] Meanwhile, the tilting member 510 includes a guide protrusion 514 protruded outwardly on one side, and the main unit 70 includes a guide groove 72 formed in a longitudinal direction to correspond to the guide protrusion 514. The presence of the guide protrusion 514 and the guide groove 72 make one end of the tilting module 50 move along a predetermined orbit of the main unit 70.

[123] Herein, since the guide groove 72 is formed between a predetermined section to limit the motion of the guide protrusion 514, the length of the section with the guide groove 72 determines the motion range of the guide protrusion 514. As a result, the length of the section determines the maximum tilting angle of the tilting member 510.

[124] Figs. 11 and 12 are side and perspective views illustrating the cover unit 60 at tilt, respectively. Specific operation of the tilting module 50 based on the tilt of the cover unit will be described hereafter by referring to the drawings.

[125] When a user tilts the cover unit 60 while the cover unit 60 is slid in the x direction, one side of the tilting member 510 tilts by the link member 520 combined with the connection protrusion 516 of the tilting member 510, while making a translational motion along the guide groove 72 of the main unit 70.

[126] Meanwhile, similarly to the first embodiment, the driver 400 is buried in the main unit 70 and applies a rotation force to the link member 520 in the second embodiment, too.

[127] The driver 400 is formed to have a threshold point within the maximum rotation angle of the link member 520. Thus, when a user applies a little force up or down the threshold point, the tilting member 510 comes to lie down or stand up steeply by the elasticity of a contacting member 440.

[128] It is also possible to form the driver 400 capable of applying rotation force to the link member 520 by changing the positions of a sliding cam 430 and rotary cam 420 so that the tilting member 510 has a tilt all the time.

[129] When the driver 400 is formed to continuously give rotation force in a tilting direction, the cover unit 60 operates to automatically have a tilt while it is slid in the x direction. [130] Meanwhile, the tilting module 50 of the second embodiment operates by reciprocal instrumental motion between the tilting member 510 and the link member 520, and one side of the tilting member 510 moves backward as the link member 520 rotates. In short, the lower part of the tilting member 510 moves backward while the tilting member 510 rotates in the second embodiment, which is different from the first embodiment where the tilting member 510 (see Fig. 5) makes a simple rotation by taking one side as a fixed rotation axis.

[131] Since the position of the guide protrusion 514 of the tilting module 50 moves backward as the tilting member 510 gets tilt, a space occupied by the entire side of the cover unit 60 can be acquired in the main unit 70.

[132]

[133] 3RD EMBODIMENT

[134] Referring to Figs. 13 to 15, a structure of a sliding device will be described in accordance with a third embodiment of the present invention.

[135] Fig. 13 is an exploded perspective view of a sliding device in accordance with a third embodiment of the present invention, and Fig. 14 is a perspective view of a tilting module shown in Fig. 13. Fig. 15 is an exploded perspective view showing a rotation interrupter.

[136] Similarly to the sliding device of the second embodiment, the sliding device of the third embodiment, too, basically includes a cover unit 80, a main unit 90, a sliding module 10, and a tilting module 50. Tilting operation of the tilting module 50 is performed by reciprocal instrumental operation between a tilting member 510 and a link member 520.

[137] Differently from the second embodiment, however, the tilting module 50 additionally includes a rotation interrupter 600 for stopping the tilting member 510 from rotating. Thus, the rotation of the tilting member 510 can be stopped optionally according to the sliding motion of the sliding module 10.

[138] To be specific, as illustrated in Fig. 15, the rotation interrupter 600 includes an anchor 610 and an interruption plate 620.

[139] While the anchor 610 is engaged with a rear part of the sliding module 10, particularly, a protrusion 270 (which is a stopper in Fig. 2) formed on a rear side of the first sliding member 200 and rotates, the interruption plate 620 makes a right and left translational motion.

[140] In the third embodiment, the anchor 610 includes a rotary wing 612 and a rotary protrusion 616.

[141] The rotary wing 612 rotates engaged with the protrusion 270 mounted on the rear side of the first sliding member 200, and the rotary protrusion 616 rotates along with the rotary wing 612. [142] With a rotary protrusion housing groove 622, the interruption plate 620 makes a right and left translational motion according to the rotation of the rotary protrusion 616.

[143] Part of the interruption plate 620 is optionally engaged with an interruption groove 92 formed in the main unit 90 to interrupt the rotation of the tilting member 510 or release the interruption.

[144] In the present embodiment, the rotary protrusion housing groove 622 is formed to have an 'L' shape on the interruption plate 620 for the sake of convenience in assembling, which is shown in Fig. 15. However, the rotary protrusion housing groove 622 may also be formed in the shape of straight line.

[145] Meanwhile, the interruption plate 620 is housed by a housing member 630 and combined with the tilting module 50. As illustrated in Fig. 15, a penetration opening 632 is formed on the housing member 630 corresponding to a cross section of the interruption plate 620 in such a manner that the interruption plate 620 makes a translational motion.

[146] Therefore, when the sliding module 10 slides in the x direction, the interruption plate 620 gets out of the interruption groove 92 by the rotation of the rotary protrusion 616 and the anchor 610 releases the rotation interruption to thereby make the tilting member 510 have a tilt. The interruption and release of the interruption by the rotation interrupter 600 will be described later with reference to Figs. 20 to 23.

[147] Subsequently, referring to Figs. 16 to 19, a specific shape of the anchor 610 will be described hereafter.

[148] Fig. 16 is perspective view showing the anchor of Fig. 13, and Fig. 17 is a plane view showing the anchor of Fig. 16. Fig. 18 is a side view showing the anchor of Fig. 16, and Fig. 19 presents a side view and a plane view of the tilting module shown in Fig. 13.

[149] As described above, the anchor 610 includes the rotary wing 612, a rotary cam 614, and the rotary protrusion 616 formed sequentially in a vertical direction.

[150] The rotary wing 612 includes a rotary groove 612a formed in a circumference to be engaged with the protrusion 270 of the first sliding member 200. Figs. 17 and 18 illustrate a pair of rotary grooves 612a formed at confronting positions of the circumference of the rotary wing 612. However, since only one groove is needed to be actually engaged with the protrusion 270, it is also possible to form a single rotary groove 612a in this embodiment.

[151] Meanwhile, as illustrated in Fig. 17, the rotary cam 614 includes two mode grooves 614a and 614b.

[152] The mode grooves 614a and 614b stops rotation of the tilting member 510 and releases the stop mode so that the tilting member 510 rotates, respectively. They are engaged with a fixing protrusion 652 (see Fig. 20) and makes the anchor 610 get fixed in a particular mode during a predetermined sliding section. [153] In the third embodiment, the fixing protrusion 652 receives elasticity from a spring

654 and gets pressed against the rotary cam 614. [154] Referring to Figs. 20 to 23, an operation of the tilting module will be described hereafter. Figs. 20 to 23 present plane views sequentially showing an operation of a rotation interrupter. [155] Referring to Fig. 20 first, when the sliding module 10 does not make an x-directional move, the fixing protrusion 652 is fixed at an interruption mode groove 614a to stop the rotation of the tilting member 510. [156] Referring to Fig. 21, when the sliding module 10 moves left in the x direction, the protrusion 270 on the rear side of the first sliding member 200 is engaged with the rotary grooves 612a of the rotary wing 612 of the anchor 610 to thereby rotate the anchor 610 in counter-clockwise. [157] As the anchor 610 rotates, the rotary protrusion 616 integrated with the anchor 610 rotates as well. The rotation of the rotary protrusion 616 is transformed into a translational motion by the rotary protrusion housing groove 622 engaged with the rotary protrusion 616 to thereby move the interruption plate 620 to the right in the x direction. [158] When the sliding motion goes on, as shown in Fig. 22, the anchor 610 rotates further in counter-clockwise, the fixing protrusion 652 is fixed at an interruption release mode groove 614b in the rotary cam 614 to thereby fixe the position of the anchor 610. [159] Upon the rotation of the anchor 610, the interruption plate 620 moves to the right completely in the x direction and gets out of the interruption groove 92 of the main unit

90. Thus, the interruption release mode is achieved and the tilting member 510 can freely rotate. [160] Subsequently, when the sliding motion goes on, as shown in Fig. 23, the first sliding member 200 moves to the left and the anchor 610 maintains a state where its position is fixed by the elasticity of the fixing protrusion 652. [161] Meanwhile, when the x-directional move of the first sliding member 200 is completed, the tilting member 510 combined with the first sliding member 200 can perform a tilting operation upward at a predetermined angle. [162] The operation for interrupting the rotation of the tilting member 510 is performed in a reverse sequence to the above-described operation. The anchor 610 rotates in clockwise by the right-directional move of the protrusion 270 of the first sliding member 200. The interruption plate 620 moves to the right by the rotation of the rotary protrusion 616 formed in the anchor 610 and is engaged with the interruption groove

92 of the main unit 90 to interrupt tilting rotation. [163] Through the above process, the fixing protrusion 652 moves from the interruption release mode groove 614b to the interruption mode groove 614a.

[164] In the third embodiment, the rotary wing 612 of the anchor 610 is formed to be rotatable by the stopper of the first sliding member. The protrusion 270 serves as the stopper but it is also possible to form a protrusion which does not serve as a stopper but for rotation of the rotary wing 612.

[165] Referring to Figs. 24 to 27, the sliding device of the present invention is applied to a personal mobile terminal and realizes diverse modes.

[166] Hereafter, a case where the sliding device of the second embodiment is applied to a personal mobile terminal will be described as an example.

[167] The sliding device may be applied to diverse devices, and the sliding device is applied to a personal mobile terminal in this embodiment.

[168] Referring to Figs. 24 and 27, the sliding device applied to a personal mobile terminal includes a display unit 62 and an auxiliary input unit 64 on the front side of the cover unit 60.

[169] The main unit 70 may be provided with diverse input units 74, 76 and/or 78. To be specific, when the sliding module 10 slides in the y direction as illustrated in Fig. 25, a first input unit 74 under the main unit 70 is uncovered in this embodiment. When it slides in the x direction as illustrated in Fig. 26, direction key-type second and third input units 76 and 78 are shown along with the first input unit 74.

[170] Since the sliding module 10 of the present embodiment can make a sliding move optionally in the x and y directions, it can realize diverse modes and provide a new input unit that is appropriate for diverse functions of a personal mobile terminal.

[171] Referring to Fig. 26, when the cover unit slides in the x direction, the cover unit 60 may tilt upward at a predetermined angle by the operation of the tilting module 50 to thereby realize the mode shown in Fig. 27.

[172] As recent personal mobile terminals are provided with diverse functions such as a Digital Multimedia Broadcasting (DMB) player and a moving picture player, cover units capable of tilting at a predetermined angle help users acquire information from the display unit conveniently.

[173] Since the cover unit 60 can tilt and at the same time its lower part can move backward by the combinative operation of the tilting member 510 and the link member 520 in the present embodiment, the input unit of the main unit 70 can have more space and users can easily manipulate the input unit.

[174] Figs. 24 to 27 illustrates the sliding device of the second embodiment applied to personal mobile terminals, but the sliding device of the first embodiment can be applied to personal mobile terminals as well. When the sliding device of the first embodiment is applied, it operates with the rotary axis of the tilting module fixed.

[175] While the present invention has been described with respect to the specific em- bodiments, it will be apparent to those skilled in the art that various changes and modifications may be made without departing from the spirit and scope of the invention as defined in the following claims.
