  The camshafts may be individually provided on the two first links 61, but it is preferable to use one camshaft 71. The camshaft 71 is formed to have a diameter that can be inserted into the mounting hole 66 a of the rotational mounting piece 66 and is longer than the length between the two rotational mounting pieces 66. The camshaft 71 has a head portion 71a having a diameter larger than that of the mounting hole 66a. The camshaft 71 is rotatably attached to the two rotational attachment pieces 66 by inserting the distal end portions into the attachment holes 66a of the two rotational attachment pieces 66 and caulking the distal end portions.

  The other end of the first link 61 is formed in a cylindrical shape that is rotatably mounted around the axis of the camshaft 71 and is formed as a rotating portion 76. A rotation portion 76 of the first link 61 is mounted around the axis of the camshaft 71 adjacent to the inside of the rotation attachment piece 66. As a result, the first link 61 is pivotally attached to the pivot attachment piece 66 via the cam shaft 71. The surface of the rotation part 76 on the side of the rotation attachment piece 66 is formed in a flat shape. Further, on the remaining surface of the rotating portion 76, for example, two engaging recesses 76a are provided at intervals of 180 ° in the circumferential direction.

  As shown in FIGS. 2, 4, 5, and 19, the first cam 72 is mounted so as to be rotatable about the axis of the camshaft 71 and is substantially the same as the rotating portion 76 of the first link 61, for example. It is formed in a cylindrical shape with a diameter. The first cam 72 is mounted around the axis of the camshaft 71 adjacent to the inside of the rotating portion 76. An engagement convex portion 72 a that engages with an engagement concave portion 76 a of the rotation portion 76 is provided on the surface of the first cam 72 on the rotation portion 76 side, and the first cam 72 rotates the camshaft 71. It is attached in a state engaged with the portion 76. That is, the first cam 72 is provided so as to be rotatable together with the first link 61 with respect to the cam shaft 71.

  As shown in FIGS. 2, 4, 5, and 20, the second cam 73 is mounted around the axis of the camshaft 71 and is formed in a cylindrical shape having substantially the same diameter as the first cam 72, for example. . The second cam 73 is provided around the axis of the camshaft 71 so as to contact the first cam 72. The surface of the second cam 73 opposite to the first cam 72 is formed in a flat shape. The peripheral surface of the second cam 73 is provided with a cam engagement recess 73 a that engages with the engagement piece 64 b of the cam holder 64, and the second cam 73 is movable only in the axial direction of the cam shaft 71. 71 is attached.

  The lift urging member 63 urges the second cam 73 to the first cam 72 and is not particularly limited. For example, the lift urging member 63 is preferably a compression spring 63 a provided on the outer periphery of the cam shaft 71. The compression spring 63a is provided on the outer periphery of the cam shaft 71 between the two second cams 73, and both end portions bias the second cam 73 toward the first cam 72, respectively. The compression spring 63a preferably has an urging force for urging the two second cams 73 toward the first cam 72 even in the fully opened state.

  The cam projection 74 is provided on the contact surface of the second cam 73, and the cam recess 75 is provided on the contact surface of the first cam 72. The cam protrusion 74 may be provided on the contact surface of the first cam 72 and the cam recess 75 may be provided on the contact surface of the second cam 73.

  As shown in FIG. 20, two cam projections 74 are provided on the contact surface of the second cam 73 at 180 ° intervals in the circumferential direction. As shown in FIG. 19, two cam recesses 75 are provided on the contact surface of the first cam 72 at intervals of 180 ° in the circumferential direction. As shown in FIG. 8, when the cam recess 75 is in the slide open state (or closed state), the cam protrusion 74 is engaged with the inclined surface 75a of the cam recess 75 (sometimes referred to as a first inclined surface 75aa). In addition, in the fully opened state, the cam convex portion 74 is engaged with the same inclined surface 75a and the inclined surface 75a on the bottom side of the first inclined surface 75aa (sometimes referred to as the second inclined surface 75ab). It is preferable to form so that it may match. In other words, the cam recess 75 is formed so that, for example, the cam protrusion 74 slides on the same inclined surface 75a when the second housing 3 lifts with respect to the first housing 2. preferable. Thereby, the urging force of the compression spring 63a acts so that the first link 61 falls to the mounting plate side via the cam convex portion 74 and the cam concave portion 75. The second housing 3 is automatically lifted down to be in a fully opened state, and the fully opened state can be held without rattling.

  Further, the cam recess 75 has a large inclination angle of the first inclined surface 75aa, and an inclined surface 75a from the first inclined surface 75aa to the bottom (an inclined surface 75a including the second inclined surface 75ab (sometimes referred to as a lift inclined surface). .)) Is preferably smaller than the inclination angle of the first inclined surface 75aa. That is, the inclination angle of the inclined surface 75a is such that when the cam convex portion 74 is engaged with the first inclined surface 75aa (the slide open state (or closed state)), the lift rotational force causes the cam convex portion 74 to be on the lift inclined surface. It is preferably formed at an angle that is weaker than the lift rotational force when engaged (including the fully opened state). That is, the inclination angle of the lift inclined surface is formed so as to increase the lift rotational force as compared with the case where the cam convex portion 74 is engaged with the first inclined surface 75aa. The inclined surface 75a and the compression spring 63a are configured to be weak at the time of up and strong at the time of lift down. In the present invention, the lift rotational force is a force acting in a direction in which the first link 61 (or the second link 62) is lifted down (tilted in the direction of the mounting plate 65), that is, a base member with respect to the mounting plate 65. The force that can automatically lift down 41.

  Next, the operation of the mobile device 1 according to the present invention will be described.

  When the portable device 1 is not used, as shown in FIG. 1A, the first housing 2 and the second housing 3 are in a closed state where they overlap each other. At this time, as shown in FIG. 9A, the slide spring 43a is deflected against the biasing force, so that the base member 41 and the slider 42 are slidably biased in the closing direction by the biasing force. Thus, the first housing 2 and the second housing 3 are held in a closed state. In order to hold the closed state more reliably, a slide locking mechanism may be provided.

  When using this portable device 1, for example, the second housing 3 is slid in the opening direction with respect to the first housing 2. Then, the length between both ends of the slide spring 43a is shortened, that is, the force when sliding is applied to the slide spring 43a via both ends of the slide spring 43a to receive the load and resist the biasing force. As a result, the slide spring 43a bends further.

  9B, the length between both ends of the slide spring 43a is minimized, that is, the both ends of the slide spring 43a are in the width direction of the first housing 2 or the second housing 3. When the slide spring 43a is positioned on a straight line extending in a straight line, the slide spring 43a is bent to a minimum. This state is a slide neutral state, and when the slide neutral state is passed, the positions of both ends of the slide spring 43a are switched and the slide spring 43a tries to return to its original shape by the urging force. That is, since both ends of the slide spring 43a are urged away from each other, the first housing 2 and the second housing 3 automatically slide in the opening direction to each other, and FIG. As shown in FIG. 1, the first housing 2 and the second housing 3 are in the slide open state.

  In the slide open state, the cam projection 74 moves along the inclined surface 75a of the cam recess 75 in the bottom direction by the biasing force of the compression spring 63a. As the cam projection 74 moves, the second housing 3 automatically lifts down with respect to the first housing 2, and as shown in FIG. The fully opened state in which the thin portion of the second housing 3 is overlaid is maintained. At this time, the overall thickness of the mobile device 1 is the thickness of the first housing 2 or the thickness of the third housing 3, and is thinner than the thickness in the closed state. Thereby, since the keyboard provided on the upper surface of the first housing 2 is exposed, keyboard operation and the like can be performed, and the portable device 1 can be used. The first housing 2 and the second housing 3 are held in the fully opened state by the urging force of the slide spring 43a and the compression spring 63a. In order to hold the fully opened state more securely, the slide lock A mechanism or a lock mechanism for the lift may be provided. Therefore, semi-automatic operation can be performed when moving from the closed state to the fully opened state.

  In order to return the second housing 3 to the original position, for example, the second housing 3 is lifted up with respect to the first housing 2 to make the slide open state, and then slides from the slide open state to the closed state. Let Then, the length between both ends of the slide spring 43a is shortened, and when the slide neutral state is passed, both ends of the slide spring 43a are urged away from each other, so that the first casing 2 and the second casing The body 3 automatically slides in the closing direction, and the first housing 2 and the second housing 3 are held in the closed state as shown in FIG. Therefore, semi-automatic operation can be performed when moving from the fully opened state to the closed state.

  Therefore, the portable device 1 according to the present invention is configured to lift the first housing 2 and the second housing 3 from the closed state to the fully open state and then lift the fully closed state. Thus, the overall thickness in the fully opened state can be reduced. In the fully opened state, the thin portion of the first housing 2 and the thin portion of the second housing 3 overlap each other, so that the overall thickness of the mobile device 1 is equal to the thickness of the first housing 2 or the first thickness. By having the thickness of the two housings 3, a smart state can be formed in the fully opened state, and the appearance is improved.

  In addition, since the inclination angle of the first inclined surface 75aa of the cam recess 75 with which the cam convex portion 74 contacts is larger than the inclination angle of the lift inclined surface from the slide open state to the closed state, the slide mechanism 4 can be smoothly performed. In other words, the urging force of the compression spring 63a always acts so that the first link 61 is tilted (rotated), but the cam projecting on the first inclined surface 75aa during the period from the closed state to the slide open state. When the portion 74 is engaged, a larger friction acts between the first housing 2 and the second housing 3 than when the cam convex portion 74 is engaged with the lift inclined surface. ing. For this reason, since the lift rotational force is weak from the slide open state to the closed state, the slide operation by the slide mechanism 4 can be performed smoothly. Further, since the tilt angle of the lift inclined surface is formed so as to increase the lift rotational force as compared with the case where the cam convex portion 74 is engaged with the first inclined surface 75aa, the lift inclined surface is at the time of lift down. Since the lift rotational force is strong, the first housing 2 and the second housing 3 can be surely automatically moved from the slide open state to the full open state, and the first housing 2 is brought into the full open state. And the 2nd housing | casing 3 can be hold | maintained reliably.

  In addition, when the angle of the second inclined surface 75ab is larger than the angle of the first inclined surface 75aa, when the lift is lowered from the slide open state to the full open state, it is surely lifted down to the full open state. it can. At this time, the closer the angle of the second inclined surface 75ab is to a right angle, the more the urging force by the compression spring 63a is applied to the first link 61, so that the lifted down state is more reliably achieved. Can be made.

  In addition, when the second housing 3 is moved from the fully opened state to the closed state with respect to the first housing 2, the force acting on the link mechanism when performing lift-up is above the rotation fulcrum of the link mechanism 6. Since it is positioned, it can be lifted up by force in the sliding direction. That is, the rotation fulcrum of the link mechanism 6 is the axis of the camshaft 71, and the force acting on the link mechanism when performing lift-up is the rotating portion of the first link 61 with the second housing 3. When the rotating portion is in the fully opened state, it is located above the camshaft 71 in the thickness direction of the first casing 2 or the second casing 3, so that the second casing is relative to the first casing 2. As a result, it is possible to lift up with the force in the direction of sliding 3, and as a result, the closing operation in the closing direction can be performed only with the force in one direction, and the closing operation can be easily performed.

  In addition, this invention is not limited to the portable apparatus of the structure as mentioned above, The 1st housing | casing and 2nd housing | casing which comprise a portable apparatus are rotated to a vertical direction (longitudinal direction) relatively. The present invention can also be applied to a structure in which the first casing is opened and closed, and a structure in which the first casing and the second casing are relatively rotated to be opened and closed. In this case, the lift mechanism, the turning mechanism, and the turning mechanism are coupled to each other. That is, a rotation mechanism (rotation hinge) or a rotation mechanism (rotation hinge) is coupled to the lift mechanism.

  21 to 26 are views showing another example of the lift mechanism according to the present invention. As shown in FIGS. 21 to 26, the lift mechanism includes, for example, a mounting plate 103 that is attached to the upper surface of the first housing 2 by screws or the like, and one end portion that is rotatably connected to the base member 102.

A central portion of the front edge portion of the mounting plate 103 is cut out in a rectangular shape, and both side portions of the cut-out portion are bent upward at substantially right angles to form second link member mounting pieces 132. These second link member mounting pieces 132 support the second link member 105 so as to be pivotable via a pivot shaft 114 and to be movable in the longitudinal direction (front-rear direction of the first housing 2). The curved long holes 133 are respectively provided. The long hole 133 is formed in such a shape that the rotating shaft 114 is positioned at one end when the slide is opened, and the rotating shaft 114 is positioned at the other end when the fully opened state. preferable.

Between the through-hole 141 of the 1st link member 104 and both sides, the cylinder which connects the 1st link member 104 and the 2nd link member 105 in X shape so that rotation is mutually possible via the rotation shaft 115. Each connecting portion 142 is provided. At the front end portion of the first link member 104, the first link member 104 is arranged substantially coaxially between the three link support portions 121 a of the base member 102 and is attached to the base member 102 via the rotating shaft 111. A link support portion 143 that is rotatably supported is provided.

A link support portion 144 that supports the member 104 so as to be rotatable is provided.

  The second link member 105 is formed in a substantially rectangular flat plate shape that can be inserted into the through hole 141 of the first link member 104. A rotating shaft 115 is inserted into the lower surface of the substantially central portion of the second link member 105, and a rotating portion 151 that supports the inserted rotating shaft 115 so as to be movable in the front-rear direction of the second link member 105. The second link member 105 and the first link member 104 are rotatably connected to each other in an X shape via the rotation shaft 115. At the front end of the second link member 105, the second link member 105 is arranged between the second link member attachment pieces 132 of the attachment plate 103 and can be rotated with respect to the attachment plate 103 via the rotation shaft 114. A cylindrical link support portion 152 is provided for support. The rear end portion of the second link member 105 is arranged substantially coaxially between the link support portions 122a of the second link member support portion 122 of the base member 102 and is connected to the base member 102 via the rotating shaft 112.

  The lift urging member 106 urges the first link member 104 or the second link member 105, for example, the first link member 104 in a direction to lift down. The lift biasing member 106 is not particularly limited, and is, for example, a torsion spring 161 or the like. The torsion spring 161 may be any type. For example, as shown in FIG. 27, the torsion spring 161 may be disposed on the outer periphery of the rotating shaft 113 between the two link support portions 131 a inside the first link member support portion 131 of the mounting plate 103. It is provided. As the torsion spring 161, for example, a substantially central portion protrudes and is formed as a contact portion 161a. The contact portion 161 a of the torsion spring 161 is in contact with the rear end portion of the mounting plate 103, and both end portions are in contact with the rear end portion of the first link member 104, so that The first link member 104 is urged in the lift-down direction. The torsion spring 161 preferably biases the first link member 104 in the lift-down direction with respect to the mounting plate 103 even in the fully opened state.

  Further, as shown in FIGS. 24 to 26, 28, and 29, the second link member mounting piece 132 includes a lift control member for reducing the lift rotational force when the slide link is in the open state to the closed state. 135 is preferably provided. For example, the lift control member 135 is provided inside each of the two second link member attachment pieces 132. Although it does not specifically limit as the lift control member 135, For example, it is formed with a synthetic resin etc., and has the curved slide long hole 136 of the substantially same shape as the long hole 133. As shown in FIG.

  Hold the rotary shaft 114 at the lift-up end on both sides in the vicinity of the end where the rotary shaft 114 is located (sometimes referred to as a lift-up end) when the slide long hole 136 is in the slide open state. Lift-up engaging portions 137 are provided. It is preferable that the lift-up engagement portion 137 does not hold the rotating shaft 114 at the lift-up end portion in a locked state, but weakens the lift rotational force. The lift-up engagement portion 137 is not particularly limited as long as the lift rotational force can be reduced, and is formed in a substantially triangular shape, for example. That is, the gap between the slide long holes 136 is narrowed by the lift-up engagement portion 137, and the lift shaft 114 rides on the lift-up engagement portion 137 when the slide shaft is opened from the fully open state. A click feeling is given to the up end. Although the lift-up engagement portion 137 is provided so that the lift rotational force is weakened, other means may be used as long as the lift rotational force can be weakened.

  Further, on both sides in the vicinity of the end opposite to the lift-up end of the slide long hole 136 (sometimes referred to as a lift-down end), a lift-down that holds the rotating shaft 114 at the lift-down end. It is preferable that the engaging part 138 is provided, respectively. The lift-down engagement portion 138 holds the rotary shaft 114 in a locked state at the lift-down end portion, that is, holds the first housing 2 and the second housing 3 in a fully opened state in a locked state. Preferably there is. The lift-down engagement portion 138 is not particularly limited as long as the rotation shaft 114 can be held in a locked state at the lift-down end portion, and is formed in a substantially triangular shape, for example. That is, the distance between the slide long holes 136 is narrowed by the lift-down engagement portion 138, and the lift shaft 114 rides on the lift-down engagement portion 138 when the slide shaft is changed from the slide open state to the full open state. When it reaches the down end, a click feeling is given. When the lift-down engagement portion 138 applies a force in the lift-up direction, the rotation shaft 114 is disengaged from the lift-down engagement portion 138 and can move from the lift-down end portion to the lift-up end portion. It is also formed in shape. Although the lift-down engagement portion 138 is provided to hold the first housing 2 and the second housing 3 in the fully opened state in a locked state, the first housing 2 and the second housing 3 As long as it can be held in the fully opened state in a locked state, it may be performed by other means.

  Even if the lift mechanism 101 is configured in this manner, the same operational effects as described above can be obtained. That is, when the mobile device 1 is used, for example, when the second housing 3 is slid semi-automatically in the opening direction with respect to the first housing 2 to be in the sliding open state, the biasing force of the torsion spring 161 causes the first The second housing 3 is automatically lifted down with respect to the one housing 2, for example, a fully opened state in which the thin portion of the first housing 2 and the thin portion of the second housing 3 are overlapped. , Held in that state. At this time, the overall thickness of the mobile device 1 is the thickness of the first housing 2 or the thickness of the second housing 3, and is thinner than the thickness in the closed state. Thereby, since the keyboard provided on the upper surface of the first housing 2 is exposed, keyboard operation and the like can be performed, and the portable device 1 can be used. In addition, when the lift-down engagement portion 138 is provided in the slide long hole 136, the rotation shaft 114 engages with the lift-down engagement portion 138 in the fully opened state. The second housing 3 can be reliably held in the fully opened state.

  In order to return the second housing 3 to the original position, for example, the second housing 3 is lifted up with respect to the first housing 2 to make the slide open state, and then slides from the slide open state to the closed state. By doing so, the first housing 2 and the second housing 3 can be moved to the closed state.

  In addition, since the rotation shaft 114 is engaged with the lift-up engagement portion 137 and the lift rotational force is weakened from the slide open state to the closed state, the slide operation by the slide mechanism 4 can be performed smoothly. it can. Further, when the lift is lowered from the slide open state to the full open state, the lift rotational force is stronger than the lift rotational force in the slide open state, so the first housing 2 and the second housing 3 are changed from the slide open state to the full open state. It can be surely moved automatically.

  As described above, the portable device according to the present invention includes the lift mechanism and the opening / closing device, and when the first housing and the second housing are in the open state, the first housing and the first housing via the lift mechanism. Since the second casing can be moved up and down relatively in the thickness direction, the overall thickness in the open state can be reduced relative to the closed state. Further, when the first housing and the second housing are in the fully opened state, the overall thickness is formed to be substantially the same as the thickness of the first housing or the second housing. Since the smart state can be formed in the opened state, it is preferably used as a mobile phone or the like among mobile devices.
