<43> Bending portions 211 and 212 are formed at opposite ends of the second plate member 21 by bending the opposite ends of the second plate member 21 upward and inward so that they face each other and accommodate opposite ends of a third plate member 32 of the movable section 30, and a first through- hole 213 having a cross-section for accommodating the first accommodation recess 225 is formed in the second plate member 21.
<44> The movable section 30 includes a fourth rectangular plate member 31 fixed to the second unit and a third plate member 32 having a cross-section corresponding to the fourth plate member and fixed to the fourth plate member
31 by laser welding, and opposite sides of the third plate member 32 are accommodated inside the bending portions 211 and 212 of the second plate member 21 by using the opening and closing device 10.
<45> First and second fixing holes 321 and 322 that are punched along the length of the third plate member 32 such that the upper sides thereof are opened are formed on opposite sides of the third plate member 32, so as to accommodate the first and second guides 221 and 222 of the first plate member 22 and fix the guide rails 40 movable along the first and second guides 221 and 222.
<46> A plurality of upwardly bent bosses 323 and 324 for inserting and catching first and second side rails 411 and 421 are formed by a predetermined interval on both sides surfaces of each of the first and second fixing holes 321 and 322.
<47> A second accommodation recess 325 is formed in the third plate member
32 between the first and second fixing holes 321 and 322 so as to maintain the accommodated resilient member 50 and thereby provide a resilient force to the second unit, by accommodating a portion of the resilient member 50 accommodated in the first accommodation recess 225 of the first plate member 22, i.e. by accommodating an protruding portion of the resilient member 50 that is accommodated in the first accommodation recess 225.
<48> As illustrated in Fig. 2, a rivet hole 326 is formed on one side of the second accommodation recess 325, i.e. in the vicinity of the second fixing hole 322 so that one end of the resilient member 50 is rotatably connected to the third plate member 32 by the medium of a rivet.
<49> The fourth plate member 31 has a cross-section corresponding to that of the third plate member 32, and a second through-hole 311 having such a cross- section that the second accommodation recess 325 is accommodated as the fourth plate member 31 is fixed to the third plate member 32 by laser welding.
<50> As illustrating in Figs. 2 to 4, first and second passages 312 and 313 for accommodating upper end portions s of the side rails 411 and 412 are punched along the lengthwise direction of the fourth plate member 31 on both sides of the second through hole 311 of the fourth plate member 31.
<5i> Insertion holes 314 and 315 for inserting ring-shaped stoppers 60 and 61 rotatable about the catching bosses 223 and 224 formed in the first plate member 22 are formed on the upper sides of the first and second passages 312 and 313.
<52> The guide rails 40 includes first and second side rails 411 and 421 inserted into opposite sides of the fixing holes 321 and 322 formed in the third plate member 32, caught by the bosses 323 and 324, and movable along the first and second guides 221 and 222 of the first plate member 22, and first and second cover plates covering the upper surfaces of the first and second side rails 411 and 421 and fixed to the fourth plate member 31 by laser welding.
<53> The resilient member 50 is formed by coupling two wire springs 51 and 52 having wave-like shapes.
<54> In other words, as illustrated in Figs. 2 to 5, the resilient member 50 has coupling portions 53 and 54 formed by separating the central wave-like portions of the two wire springs 51 and 52 whose free ends are wound outward and then folding the wire springs 51 and 52 and connecting the wire springs 51 and 52 by laser welding.
<55> The coupling portions 53 and 54 of the resilient member 50 are rotatably fixed to the hole 226 formed in the first accommodation recess 225 of the first plate member 22 and the rivet hole 326 formed in the second accommodation recess 325 of the third plate member 32 by the medium of rivets.
<56> Hereinafter, the operation of the opening and closing device for use in a portable device according to the embodiment of the present invention will be described in detail.
<57> If the user slides the second unit in order to use a mobile phone in the state of Fig. 6, the second unit is slid upward with respect to the first unit as illustrated in Fig. 6. That is, the first and second side rails 411 and 421 of the guide rails 40 inserted into and fixed to the first and second fixing holes 321 and 322 formed in the third plate member of the movable section 32 are moved along the first and second guides 221 and 222 formed in the first plate member 22 of the fixed section 20.
<58> When the movable section 30 is moved, the resilient member 50 accommodated in both the first accommodation recess formed in the first plate member 22 of the fixed section 20 and the second accommodation recess 325 formed in the third plate member 32 of the movable section 30 becomes gradually compressed so that the coupling portions formed at opposite ends of the resilient member 50 are horizontally located.
<59> The, when the movable section 30 is moved upward further and the resilient member 50 is deviated from the horizontal state, the movable section 30 is automatically moved upward by the resilient member 50 along the first and second guides 221 and 222 of the fixed section 20, thus opening the mobile phone into a usable state.
<60> As mentioned above, in the opening and closing device for use in a portable device according to the embodiment of the present invention, since the resilient member accommodated in both the first accommodation recess formed in the first plate member of the fixed section and the second accommodation recess formed in the third plate member of the movable section provides a resilient force to the movable section, the thickness of the opening and closing device can be made thinner. [Mode for Invention]
<6i> Figs. 8 and 12 illustrate an opening and closing device for use in a portable device according to another embodiment of the present invention.
<62> As illustrated, the opening and closing device for use in a portable device according to the embodiment of the present invention includes a fixed plate 110 to which a first unit is fixed, a movable plate 120 connected to the fixed plate 110 by the medium of a plurality of coupling pins 150 and 151 and fixed to the second unit, and a resilient unit 130 whose end is rotatably connected to the movable plate 120 and whose length is varied by slide movements of a plurality of resilient members 133 to provide a resilient force to the movable plate 120.
<63> Hereinafter, the opening and closing device for use in a portable device according to the embodiment of the present invention will be described in detail.
<64> The fixing plate 110 is a rectangular plate, and first and second guide rail passages 111 and 112 are formed on opposite sides of the fixing plate 110 along the length of the fixing plate 110 so that the movable plate 120 connected by the medium of the coupling pins 150 and 151 caught by interposing the movable plate 120 and the ring 140 and 141 is moved.
<65> A first through-hole 113 is formed between the first and second guide rail passages 111 and 112 so that the thickness of the opening and closing device 100 is prevented from being thicker by accommodating the resilient unit 130 whose end is rotatably connected to the fixed plate 110 and the movable plate 120.
<66> A connection hole 114 for rotatably connecting one end of the resilient unit 130 by the medium of a rotary pin 160 is formed between the second guide rail passage 112 and the first through-hole 113.
<67> The movable plate 120 is a rectangular plate corresponding to the fixed plate 110, and as illustrated in Figs. 8 and 9, first and second connection holes 121 and 122 spaced apart from each other and passing through the first and second guide rail passages 111 and 112 to pass and catch ends of the coupling pins 150 and 151 caught by interposing rings 140 and 141 are formed at positions corresponding to the first and second guide rail passages 111 and 112.
<68> A second through-hole 123 is formed between the first and second connection holes 121 and 122 to partially accommodate the thickness of the resilient unit 130 and make the entire thickness of the opening and closing device 100 thinner.
<69> A pin hole 124 for rotatably connecting the opposite end of the resilient unit 130 by the medium of the connection pin 170 is formed between the second through-hole 123 and the first connection hole 121 formed in the movable plate 120.
<70> As illustrated in Figs. 9 and 10, one end of the resilient unit 130 is rotatably connected to the connection hole 114 formed in the fixed plate 110 and the opposite end thereof is rotatably connected to the pin hole 124 formed in the movable plate 120 to provide a resilient force to the second unit .
<7i> The resilient unit 130 includes a first resilient force transfer bar 131 whose end corresponds to the connection hole 114 of the fixed plate 110 to be rotatably connected to the connection hole 114 by the medium of the rotary pin 160, a second resilient force transfer bar 132 slidably folded on the upper surface of the first resilient force transfer bar 131 and whose end is rotatably connected to the pin hole 124 of the movable plate 120 by the medium of the connection pin 170, and a plurality of resilient members 133 for providing a resilient force toward the movable plate 120 by which ends thereof are caught to the first and second resilient force transfer bars 131 and 132.
<72> Here, the resilient members 133 are compression springs for providing the movable plate 120 with a resilient force.
<73> As illustrated in Fig. 9, ends of the first and second resilient force transfer bars 131 and 132 have T-shaped cross-sections having extension pieces 1311 and 1321 extending to opposite sides thereof. Central portions of the first and second resilient force transfer bars 131 and 132 correspond to each other. Guide grooves 1312 (guide grooves formed in the second resilient transfer bar are not shown in the figures) are formed on opposite inner surfaces of the first and second resilient force transfer bars 131 and 132 so that the first and second resilient force transfer bars 131 and 132 are slidably inserted with respect to each other.
<74> Moreover, holes 1313 and 1323 through which the rotary pin 160 and the connection pin 170 pass are formed on the opposite ends of the first and second resilient force transfer bars 131 and 132.
<75> Guide bosses 1314 and 1324 inserted into the guide grooves 1312 not to be separated therefrom are formed on opposite side surfaces of the first and second resilient force transfer bars 131 and 132 in the vicinity of the holes 1313 and 1323.
<76> First and second catching holes 1315 and 1325 through which ends of the resilient members 133 are partially inserted and caught are formed by a predetermined interval on surfaces of the extension pieces 1311 and 1321 extending to the opposite sides with respect to central portions of the first and second resilient force transfer bars 131 and 132, and first and second accommodation recesses 1326 (the first accommodation recesses are not shown) ends of which are connected to the first and second catching holes 1315 and 1325 and the opposite ends of which are opened so that the caught resilient members 133 do not protrude.
<77> The operation of the opening and closing device for use in a portable device according to the embodiment of the present invention will be described in detail with reference to Figs. 8 to 12.
<78> If the user slides the second unit in the state of Fig. 11 to use a mobile phone, the second unit is slid upward with respect to the first unit as illustrated in Fig. 11. That is, the movable plate 120 is moved along the first and second guide rail passages 111 and 112 of the fixed plate 110.
<79> When the movable plate 120 is moved, the second resilient force transfer bar 132 of the resilient unit 130 accommodated in the first and second through-holes 113 and 123 of the fixed plate 110 and the movable plate 120 is slid on the upper surface of the first resilient force transfer bar 132 to compress the resilient members 133 and, at the same time, the extension pieces 1321 of the second resilient force transfer bar 132 approach the extension pieces of the first resilient force transfer bar 131.
<80> Then, if the movable plate 120 is moved upward further and the resilient members 133 are deviated from the horizontal state, the movable plate 120 is automatically moved upward along the first and second guide rail passages 111 and 112 of the fixed plate 110 by the resilient unit 130 whereby the mobile phone is opened into a usable state as illustrated in Fig. 12.
<8i> As mentioned above, in the opening and closing device for use in a portable device according to the embodiment of the present invention, since the resilient unit is rotatably accommodated in the first and second through- holes formed in the fixed plate and the movable plate, the opening and closing device can become thinner.
<82> Although the preferred embodiments of the present invention have been disclosed for illustrative purposes, those skilled in the art will appreciate that various modifications, additions and substitutions are possible, without departing from the scope and spirit of the invention as disclosed in the accompanying claims.
