Description

  The present invention relates to a mobile phone in which a transmitter and a receiver are rotatably connected.

  In general, in a mobile phone, a transmitter and a receiver are coupled so as to be rotatable about a single rotation axis that is parallel to the front surface thereof. However, in such a mobile phone, the posture of the receiving unit relative to the transmitting unit can only be changed two-dimensionally, and cannot be changed three-dimensionally. Therefore, recently, a mobile phone in which a transmitter and a receiver are connected so as to be rotatable around two rotation axes orthogonal to each other has been used. In such a mobile phone, by rotating the receiving unit around the first and second rotation axes, various directions can be directed to the transmitting unit. For example, the front face of the receiver can be made to face the front face of the transmitter, or the back face of the receiver can be made to face the front face of the transmitter (see Patent Documents 1 and 2).

Within the range of one auction angle, the receiver unit is moved from the transmitter unit to the first terminal unit as the receiver unit rotates from the first starting end position to the first terminal end side about the first rotation axis. The transmitter is separated along the rotation axis, and the receiver is rotated from the first terminal position to the first start position with the first rotation axis as the center. It is made to approach along the said 1st rotation axis.

Within the range of two hoisting angles, the receiving unit is moved from the transmitting unit to the first starting point as the receiving unit rotates from the first terminal position to the first starting position side about the first rotation axis. The transmitter is separated along the rotation axis, and the receiver is rotated from the first start end position to the first end position with the first rotation axis as the center. It is made to approach along the said 1st rotation axis.
In this case, the second displacement mechanism causes the second receiving mechanism to rotate the receiver unit about the second rotation axis as the receiver unit rotates about the first rotation axis. A mechanism is desirable.

  According to the mobile phone of the first to sixth inventions, when the receiving unit rotates from the first start position to the first end position with the first rotation axis as the center, the first end position is the first to the first end position. When turning to the start end position, when turning from the first end position to the first start end position side, or when turning from the first start end position side to the first end position, the receiver unit is moved from the transmitter unit. It is displaced so as to be separated or approached along the first rotation axis. Therefore, as compared with the conventional mobile phone in which the receiving unit simply rotates on the plane around the first rotation axis, the front of the receiving unit pushes the operation button provided on the front of the transmitting unit. The situation can be reduced or prevented.

  The best mode for carrying out the present invention will be described below with reference to FIGS. 1 to 15 show a mobile phone 1 according to the present invention. The cellular phone 1 includes a transmitter 2, a receiver 3, and a hinge device 4 (see FIGS. 9 to 15).

  The transmitter 2 is composed of two halves 2A and 2B, as shown in FIG. 1 and FIGS. The two halves 2A and 2B have a rectangular parallelepiped shape with a small thickness, are overlapped with each other in the thickness direction, and are fixed by screws B1 (see FIGS. 13 and 14). The front surface 2a of the transmitter 2 is a flat surface having a substantially rectangular shape in plan view. A shallow mounting recess 2b extending in the width direction of the front surface 2a is formed at one end of the front surface 2a in the longitudinal direction. A mounting plate (hinge body) 41 of the hinge device 4 described later is mounted on the bottom surface of the mounting recess 2b. Various operation buttons 2c, a microphone (not shown), and others are provided on a portion of the front surface 2a on the other end side from the mounting recess 2b.

  Similarly to the transmitter 2, the receiver 3 is composed of two halves 3 </ b> A and 3 </ b> B having a thin rectangular parallelepiped shape. The two halves 3A and 3B are overlapped in the thickness direction and fixed by screws B2 (see FIG. 13). The width of the receiver 3 is almost the same as the width of the transmitter 2, and the length of the receiver 3 is slightly shorter than the length of the transmitter 2. The front surface 3a of the receiver 3 is a flat surface that is substantially rectangular in plan view. A liquid crystal display unit 3b, a speaker (not shown), and others are provided on the front surface 3a. One end surface in the longitudinal direction of the receiver 3 is a semicircular arc surface 3c having a semicircular cross section extending from one side to the other in the width direction of the receiver 3. An accommodation recess 3d is provided at the center in the width direction of one end where the arc surface 3c is formed. The housing recess 3 d accommodates a portion protruding from the mounting recess 2 b of the hinge device 4 attached to the transmitter 2.

  The transmitter 2 and the receiver 3 are connected by a hinge device 4 so as to be rotatable about the first rotation axis L1 and the second rotation axis L2. The first rotation axis L1 is disposed so as to be orthogonal to the front surface 2a at the center in the width direction of one end portion in the longitudinal direction of the front surface 2a. On the other hand, the second rotation axis L2 extends in parallel with the front surface 2a in the width direction of the front surface 2a. In addition, the second rotation axis L2 is orthogonal to the first rotation axis L1. The second rotation axis L2 may be arranged away from the first rotation axis L1 toward one end side or the other end side in the longitudinal direction of the front surface 2a. The angle formed by the first rotation axis L1 and the second rotation axis L2 is preferably a right angle in any case, but may be deviated from the right angle as long as it is a slight angle.

  The center line of the arc surface 3c of the receiver 3 is made to coincide with the second rotation axis L2. Moreover, the radius of curvature of the circular arc surface 3c is set to be substantially the same as or slightly smaller than the interval between the second rotation axis L2 and the front surface 2a. Therefore, the receiver 3 can be rotated about the second rotation axis L2 even if it is rotated to any position about the first rotation axis L1.

  For explaining the rotation range of the transmitter 2 and receiver 3 around the first and second rotation axes L1 and L2, for convenience of explanation, the transmitter 2 is fixed in position, and the receiver 3 is It shall rotate with respect to the transmission part 2. FIG. Now, it is assumed that the receiver 3 is located at the folding position shown in FIGS. Hereinafter, the circumferential position around the first rotation axis L1 of the receiver 3 at this time is referred to as a first starting end position, and the circumferential position around the second rotation axis L2 is a second starting end position. Called. Therefore, the receiver 3 is positioned at the folding position when it is rotated to the first start position about the first rotation axis L1 and is rotated to the second start position about the second rotation axis L2. It will be. When the receiver 3 is located at the first starting position, both side surfaces 3e, 3f of the receiver 3 in the second rotation axis L2 direction are on the same plane as both side surfaces 2e, 2f of the transmitter 2 in the same direction. As a result, the receiver 3 is located at the same position as the transmitter 2 in the circumferential direction around the first rotation axis L1. When the receiver 3 is located at the second starting position, the front surface 3 a of the receiver 3 abuts against the front surface 2 a of the transmitter 2. In other words, the second starting end position of the receiver 3 is restricted by the front face 3a hitting the front face 2a. As shown in FIG. 1 (A), a small protrusion 2d is formed at the center in the width direction of the other end of the front surface 2a, and the front surface 3a of the receiver 3 is abutted against the small protrusion 2d. 2 The starting position may be regulated. Further, the second start end position may be regulated by the hinge device 4, and in this case, the front surface 3a is slightly separated in a state parallel to the front surface 2a when the receiver 3 is located at the second start end position. You may let them.

  With respect to the first rotation axis L1, the receiver 3 can be rotated 180 ° from the first starting end position in the clockwise direction in FIG. 1A (in the direction of arrow A in FIG. 2). Accordingly, when the position 180 ° away from the first start position in the clockwise direction in FIG. 1A is the first end position, the earpiece 3 has the first start position and the first position about the first rotation axis L1. It can be rotated between one end position. The rotation range around the first rotation axis L1 of the receiver 3 is limited by the hinge device 4 as will be described later. In addition, when the receiver 3 is located at the first start position and the first end position, the hinge device 4 provides a click feeling, that is, with a predetermined amount of force, to the first start position and the first end position. To be maintained. The rotation range of the reception unit 3 is not limited to 180 ° and can be changed as appropriate. For example, the receiver 3 not only can rotate between the first start position and the first end position, but further rotates by, for example, 90 ° from the first start position in the counterclockwise direction of FIG. Alternatively, it may be possible to rotate 360 ° around the first rotation axis L1.

  The receiver 3 is rotatable about the second rotation axis L2 by 180 ° from the second starting end position in the clockwise direction in FIG. As described above, the second starting end position of the reception unit 3 is regulated by the front surface 3 a abutting against the front surface 2 a of the transmission unit 2. Assuming that the position where the receiver 3 is rotated 180 ° from the second start position is the second end position, the back end 3g of the receiver 3 is the front surface 2a of the transmitter 2 as shown in FIG. It is regulated by hitting. The second terminal position may be regulated by the hinge device 4. In that case, when the receiver 3 is located at the second terminal position, the back surface 3g may be slightly separated in a state parallel to the front surface 2a. In any case, when the receiving unit 3 is located at the second terminal position, the back surface 3g of the receiving unit 3 is located on substantially the same plane as the front surface 2a of the transmitting unit 2. The receiver 3 is connected to the second start position from the second end position by the hinge device 4 between the second start position and a position away from the second start position by a predetermined angle (for example, 15 °) toward the second end position. It is urged to rotate in the direction toward the position, and is rotated to the second start end position by the rotation urging force and is maintained at the second start end position. On the other hand, the reception unit 3 is connected to the second end position by the hinge device 4 between the second end open position and a position away from the second end position by a predetermined angle (for example, 15 °) toward the second start position. Is urged to rotate toward the second end position, and is urged to rotate to the second end position by the rotation urging force and is maintained at the second end position. When the receiving unit 3 rotates to the talking position shown in FIG. 5 that is separated from the first starting position by a predetermined angle (for example, 160 °) toward the second terminal position with the second rotation axis L2 as the center, the hinge device 4 It is stopped at the call position with a click feeling, that is, with a predetermined amount of force.

  As described above, the receiving unit 3 can rotate 180 ° around the first rotation axis L1 and can rotate 180 ° around the second rotation axis L2. 2 and the folding position shown in FIG. 2 (the rotation angles around the first and second rotation axes L1 and L2 from the first and second starting end closed positions are both 0 °; hereinafter, 0 ° and 0 °) 3), the self-portrait position (180 °, 0 °) shown in FIG. 3, the open position (0 °, 180 °) shown in FIG. 4, the call position (0 °, 160 °) shown in FIG. Can be rotated to the reverse folding position (180 °, 180 °) shown in FIG. In the reverse folding position, the side surfaces 3e and 3f of the receiver unit 3 are located on the same plane as the side surfaces 2f and 2e of the transmitter unit 2, respectively.

  When the earpiece 3 is located at the folding position shown in FIGS. 1 and 2, and starts to turn from the first start position toward the first end position around the first rotation axis L1, At the same time, the first rotation displacement mechanism (first separation rotation mechanism; second approach rotation mechanism) 5 provided between the transmission section 2 and the reception section 3 performs the first rotation about the second rotation axis L2. 2 is forcibly rotated from the start position to the second end position. In this case, the reception unit 3 is centered on the second rotation axis L2 while rotating from the first start position to the first displacement position separated by a predetermined angle (for example, 10 °) from the first start position. As described above, the first end position is rotated from the second start position toward the second end position by a predetermined angle (for example, 5 °). As a result, the front surface 3a of the reception unit 3 starts to rotate from the folding position (first start position) to the first end position side with respect to the first rotation axis L1. Is separated from the front surface 2a. Therefore, the front surface 3 a of the receiver 3 does not contact the operation button 2 c provided on the front surface 2 a of the receiver 2. Therefore, malfunction of the mobile phone 1 can be prevented. Further, when the receiver 3 rotates from the first displacement position to the folding position around the first rotation axis L1, the first rotation displacement mechanism 5 causes the second rotation axis L2 to be the center. It can be turned from the first escape position to the folding position, and the front face 3a of the receiving section 3 contacts the front face 2a of the sending section 2 until the receiving section 3 is turned to the folding position. There is no. Therefore, at this time, the front surface 3a of the receiver 3 does not come into contact with the operation button 2c of the transmitter 2, so that the mobile phone 1 can be prevented from malfunctioning. Note that the angle (5 °) between the second start position and the first escape position is such that the hinge device 4 moves the receiver 3 from the second end position side to the second start position with the second rotation axis L2 as the center. It is set to be smaller than the above-mentioned angle range (15 °) that can be urged to rotate.

  When the receiver 3 is located at the self-portrait position shown in FIG. 3, the second displacement position separated from the first terminal position by a predetermined angle from the first terminal position about the first rotation axis L <b> 1. Is rotated by the first rotational displacement mechanism 5 to the second escape position separated from the second start position by a predetermined angle with the second rotational axis L2 as the center. On the other hand, when the second displacement position is rotated to the first terminal position, the first rotation displacement mechanism 5 forcibly rotates the second escape position to the second start position. The angle between the first terminal position and the second displacement position is set to be the same as the angle (10 °) between the first start position and the first displacement position, and the first clearance position and the second clearance position are set. The position is set at the same position. When the receiver 3 rotates between the first displacement position and the second displacement position about the first rotation axis L1, the second rotation displacement mechanism 5 causes the first escape position (= second). The escape position is maintained.

  In the case where the receiver 3 is located at the reverse folding position shown in FIG. 6, when the receiver 3 starts to rotate from the first terminal position toward the first starting position about the first rotation axis L <b> 1, A second terminal around the second rotation axis L2 by a second rotation displacement mechanism (second separation rotation mechanism; second approach rotation mechanism) 7 provided between the transmitter 2 and the receiver 3. It is forcibly rotated from the position to the second starting end position side. In this case, the receiver 3 rotates while rotating about the first rotation axis L1 from the first terminal position to the third displacement position away from the first start position by a predetermined angle (for example, 10 °). The second rotation axis L2 is rotated from the second end position toward the second start end position by a predetermined angle (for example, 5 °) to a third escape position. As a result, the back surface 3g of the receiving unit 3 starts to rotate from the reverse folding position (first terminal position) to the first starting position side around the first rotation axis L1, and at the same time, It is separated from the front surface 2 a of the part 2. Therefore, the back surface 3g of the receiver 3 does not come into contact with the operation button 2c provided on the front surface 2a of the receiver 2. Therefore, malfunction of the mobile phone 1 can be prevented. Further, when the receiver 3 rotates from the third displacement position to the first terminal position about the first rotation axis L1, the second rotation displacement machine 7 sets the second rotation axis L2 as the center. It can be rotated from the third escape position to the reverse folding position, and the back surface 3g of the reception unit 3 contacts the front surface 2a of the transmission unit 2 until the reception unit 3 rotates to the reverse folding position. There is nothing to do. Therefore, also at this time, the back surface 3g of the receiver 3 does not come into contact with the operation button 2c of the transmitter 2, so that the mobile phone 1 can be prevented from malfunctioning. Note that the angle (5 °) between the second end position and the escape position is such that the hinge device 4 rotates the receiver 3 from the second start position side to the second end position about the second rotation axis L2. It is set to be smaller than the above-mentioned angle range (15 °) that can be energized.

  When the receiver 3 is located at the open position shown in FIG. 4, the first receiving axis position is shifted from the first starting end position toward the first ending position by a predetermined angle about the first rotation axis L <b> 1. When it rotates, it is forcibly rotated by the second rotation displacement mechanism 7 to the fourth escape position that is separated from the second terminal position by a predetermined angle about the second rotation axis L2. On the other hand, when rotating from the fourth displacement position to the first start position, the second rotation displacement mechanism 7 forcibly rotates the fourth escape position to the second end position. The angle between the first start position and the fourth displacement position is set to be the same as the angle (10 °) between the first end position and the third displacement position, and both angles are the first start position. And the angle between the first displacement position and the angle between the first terminal position and the second displacement position. Further, the fourth clearance position is set to be the same as the third clearance position, and the angle between the second terminal position and the third bow position, and between the second terminal position and the fourth clearance position. The angle is set to be the same as the angle between the second start end position and the first escape position and the angle between the second start end position and the second escape position. When the receiver 3 rotates between the third displacement position and the fourth displacement position about the first rotation axis L1, the second displacement mechanism 7 causes the third clearance position (= fourth clearance). Position).

  Next, the hinge device 4 for connecting the receiver 3 to the transmitter 2 so as to be rotatable about the first and second rotation axes L1 and L2, and the transmitter 3 are first rotated. The first and second rotational displacement mechanisms 5 and 7 that prevent the front surface 3a of the receiver 3 from slidingly contacting the front surface 2a of the transmitter 2 when rotating about the axis L1 will be described.

  As shown in FIGS. 16 to 24, the hinge device 4 has a mounting plate 41. One end portion (a lower end portion in FIGS. 22 and 23) of a cylindrical support cylinder 42 is fixed to the center portion of the mounting plate 41. A hinge body of the hinge device 4 is constituted by the mounting plate 41 and the support cylinder 42. Therefore, the mounting plate 41 and the support tube 42 may be formed integrally. That is, you may form the whole hinge main body integrally.

  On the outer peripheral surface of the other end portion (upper end portion in FIG. 22) of the support cylinder 42, one end portion (lower end portion in FIG. 22) of the rotating member 43 having a cylindrical shape is the axis of the support cylinder 42 (first rotation axis L1). ), And is movably fitted in the axial direction of the support cylinder 42. However, the rotating member 43 is pressed against the flange portion 42 a of the support cylinder 42 by a coil spring 45 described later, and does not substantially move in the axial direction with respect to the support cylinder 42. A pair of guide grooves 43 a are formed on one end face of the rotating member 43 so as to be 180 ° apart in the circumferential direction.

  A fitting hole 44a formed in the central portion of the movable member 44 is rotatable on the outer peripheral surface of the support tube 42 located between the rotation member 43 and the mounting plate 41, and the axial direction of the support tube 42 It is fitted to be movable. The movable member 44 has a substantially rectangular plate shape, and its longitudinal direction is directed in a direction orthogonal to the axis of the support cylinder 42 and the axis (second rotation axis L2) of the projecting cylinder portions 43b and 43c described later. Has been placed. One end 44e and the other end 44f in the longitudinal direction of the movable member 44 are inserted into the pair of guide grooves 43a and 43a of the rotating member 43 so as to be slidable and non-rotatable. Thereby, the movable member 44 is connected to the rotating member 43 so as not to rotate and to be movable in the axial direction of the support cylinder 42. One end 44e and the other end 44f of the movable member 44 project through the guide grooves 43a and 43a, respectively, and protrude from the rotating member 43 to the outside.

  A rotation restricting protrusion 44 b is formed on the inner peripheral surface of the fitting hole 44 a of the movable member 44. The rotation restricting projection 44b is inserted into a cutout portion 42b formed in the peripheral wall portion of the support cylinder 42 so as to be movable in the circumferential direction of the support cylinder 42. When the rotation member 43 and the movable member 44 rotate about the axis of the support cylinder 42, the rotation restriction projection 44 b abuts against one side surface and the other side surface of the notch portion 42 b in the circumferential direction of the support cylinder 42. Thereby, the rotation range of the rotation member 43 and the movable member 44 is limited.

  As shown in FIGS. 23 and 24, a coil spring (biasing means) 45 is provided between the rotating member 43 and the movable member 44. The coil spring 45 presses the rotating member 43 against the flange portion 42 a of the support cylinder 42 to fix the position, and biases the movable member 44 toward the mounting plate 41, so that the movable member 44 and the mounting plate 41 are opposed to each other. The surfaces are in contact with each other.

  A pair of convex portions 41 a and 41 b are formed on the surface of the mounting plate 41 facing the movable member 44. Therefore, in the mounting plate 41, only the pair of convex portions 41 a and 41 b is actually in contact with the movable member 44. The pair of convex portions 41 a and 41 b are disposed 180 degrees apart in the circumferential direction on the circumference centered on the axis of the support cylinder 42. About a pair of convex part 41a, 41b, you may comprise by a part of spherical body. That is, a pair of spheres may be embedded in the facing surface of the mounting plate 41 with a part of the spheres protruding from the facing surface, and the portions protruding from the facing surfaces of the spheres may be convex portions 41a and 41b.

  As shown in FIGS. 23 to 26, a pair of concave portions 44 c and 44 d are formed on the surface of the movable member 44 that faces the mounting plate 41. The pair of concave portions 44c and 44d are arranged 180 degrees apart in the circumferential direction on the same circumference as the circumference where the convex portions 41a and 41b are arranged. Therefore, when the movable member 44 and the rotating member 43 are rotated to predetermined positions, the convex portions 41a and 41b are fitted into the concave portions 44c and 44d, respectively. In this state, the movable member 44 and the rotating member 43 are fixed to the mounting plate 41 with a predetermined amount of force by a biasing force of the coil spring 45 with a click feeling. Hereinafter, the position of the movable member 44 and the rotation member 43 at this time is referred to as a first rotation start end position. When the movable member 44 and the rotation member 43 are rotated 180 ° from the first rotation start position about the axis of the support cylinder 42 (first rotation axis L1), the convex portions 41a and 41b are respectively formed in the concave portions 44d and 44c. Fit. Hereinafter, the position of the movable member 44 at this time is referred to as a first rotation end position. The movable member 44 and the rotation member 43 are fixed to the mounting plate 41 with a click feeling by the biasing force of the coil spring 45 even at the first rotation end position.

  The first rotation start end position and the first rotation end position are one limit position of the rotation range of the movable member 44 and the rotation member 43 limited by the rotation restricting projection 44b and the notch 42b. Each of the other limit positions is set at substantially the same position. Therefore, the rotation range of the movable member 44 is substantially limited between the first rotation start end position and the first rotation end position.

  When the movable member 44 rotates from the first rotation start end position to the second rotation end position, the convex portions 41a and 41b move so as to escape from the concave portions 44c and 44d. When the movable member 44 rotates by a predetermined angle from the first rotation start position, the convex portions 41a and 41b completely escape from the concave portions 44c and 44d and abut against the surface of the movable member 44 facing the mounting plate 41. As a result, the movable member 44 is moved by a predetermined distance so as to be separated from the mounting plate 41 against the urging force of the coil spring 45. Conversely, when the movable member 44 rotates from the position away from the first rotation start end position by a predetermined angle to the first rotation start end position, the convex portions 41a and 41b that abut against the opposing surface of the movable member 44 are recessed. 44d and 44c are entered. As a result, the movable member 44 is moved by a predetermined distance so as to approach the mounting plate 41 by the biasing force of the coil spring 45. The angle at which the movable member 44 rotates about the support cylinder 42 while the convex portions 41a and 41b protrude and retract relative to the concave portions 44c and 44d is determined by the folding position of the receiver 3 about the first rotation axis L1. It is set to be the same as the rotation angle (10 °) when rotating between the first displacement positions. Further, the distance at which the movable member 44 approaches and separates from the mounting plate 41 by the protrusions 41a and 41b projecting and retracting with respect to the recesses 44c and 44d rotates the receiver 3 from the folding position to the first escape position. It is set to the distance necessary to make it.

  When the movable member 44 rotates between the first rotation end position and a position away from the first rotation end position by a predetermined distance toward the first rotation end position, the convex portions 41a and 41b are moved with respect to the concave portions 44d and 44c. Each appears. Therefore, also in this case, the movable member 44 moves closer to and away from the mounting plate 41 as it rotates. The angle at which the movable member 44 pivots around the support tube 42 while the convex portions 41a and 41b are projected and retracted with respect to the concave portions 44d and 44c is such that the convex portions 41a and 41b have the same dimensions and shape as each other. Since 44c and 44d have the same size and the same shape as each other, the angle at which the movable member 44 rotates around the support cylinder 42 while the convex portions 41a and 41b project and retract relative to the concave portions 44c and 44d is the same. And the angle (10 °) when the receiver 3 rotates between the reverse folding position (first terminal position) and the third displacement position around the first rotation axis L1 is set to be the same. ing. Similarly, the distance that the movable member 44 approaches and separates from the mounting plate 41 by the protrusions 41a and 41b protruding and protruding with respect to the recesses 44d and 44c is the distance between the protrusions 41a and 41b protruding and protruding with respect to the recesses 44c and 44d. By doing so, the distance is the same as the distance at which the movable member 44 approaches and separates from the mounting plate 41, and is set to a distance necessary to rotate the receiver 3 from the reverse folding position to the third escape position.

  A pair of protruding cylindrical portions 43b and 43c are provided at the other end portion of the outer peripheral surface of the rotating member 43 (the end portion opposite to the mounting plate 41 side, that is, the upper end portion in FIG. 22). The pair of projecting cylindrical portions 43b and 43c are arranged 180 ° apart from each other in the circumferential direction of the rotating member 43 and 90 ° apart from the guide groove 43a. In addition, the protruding cylinder portions 43b and 43c are arranged so that their axis lines (second rotation axis L2) coincide with each other and orthogonal to the axis line of the support cylinder 42. As shown in FIG. 21, the inside of one protruding cylinder portion (the right protruding cylinder portion in FIG. 22) 43 b passes through the peripheral wall portion of the rotating member 43 and opens to the inner peripheral surface of the rotating member 43. Yes. The inside of the other protruding cylindrical portion 43 c is blocked from the inside of the rotating member 43 by the peripheral wall portion of the rotating member 43.

  One end of the connecting cylinder 46 is fitted to the inner peripheral surface of the one protruding cylinder 43b so as not to rotate. A locking claw (not shown) is formed on the outer peripheral surface of one end of the connecting cylinder 46, and the connecting cylinder 46 protrudes when the engaging claw engages with the base end of the protruding cylinder 43b. The cylinder 43b is prevented from coming off. One end of the first connecting arm 47 is rotatably fitted to the outer periphery of the other end protruding from the support tube 43b of the connecting tube 46 to the outside. Therefore, the 1st connection arm 47 is connected with the rotation member 43 so that rotation is possible centering | focusing on the axis line of the protrusion cylinder part 43b. The receiver 3 is attached to the other end of the first connecting arm 47 as will be described later.

  A disc-shaped movable plate 48 is fitted to the tip of the inner peripheral surface of the other protruding cylindrical portion 43c so as not to rotate and to be movable in the axial direction of the protruding cylindrical portion 43c. A hinge shaft 49 having an axis aligned with the axis of the protruding cylinder 43c is disposed inside the protruding cylinder 43c. The proximal end portion of the hinge shaft 49 penetrates the peripheral wall portion of the turning member 43 so as to be rotatable, and the distal end portion penetrates the central portion of the movable plate 48 so as to be rotatable. As a result, the hinge shaft 49 is rotatably supported by the protruding cylinder portion 43c in a state where the axis thereof coincides with the axis of the protruding cylinder portion 43c. A rotating plate 50 is rotatably fitted to the outer peripheral surface of the distal end portion of the hinge shaft 49 penetrating the movable plate 48, and one end portion of the second connecting arm 51 is non-rotatably fitted to the distal end side thereof. Are combined. Therefore, the second connecting arm 51 is rotatably connected to the rotating member 43 via the hinge shaft 49. The rotating plate 50 is connected to the second connecting arm 51 so as not to rotate. Therefore, the rotating plate 50 and the second connecting arm 51 may be formed integrally. The second connecting arm 51 is connected to the rotating member 43 by a hinge shaft 49 so as not to move radially outward. Note that the receiver 3 is attached to the other end of the second connecting arm 51. A coil spring 52 is provided between the inner peripheral surface of the protruding cylindrical portion 43 c and the outer peripheral surface of the hinge shaft 49. The coil spring 52 urges the movable plate 48 toward the rotating plate 50.

  As shown in FIGS. 22 and 27, a pair of housing recesses 48 a and 48 b are formed on the surface of the movable plate 48 that faces the rotating plate 50. The pair of housing recesses 48a and 48b extend in the radial direction of the movable plate 48 and are arranged symmetrically with respect to the axis of the protruding cylinder 43c. That is, they are arranged 180 ° apart in the circumferential direction on the circumference centering on the axis of the protruding cylinder portion 43c. Spheres 53A and 53B are accommodated in the accommodating recesses 48a and 48b, respectively. The spherical bodies 53A and 53B are accommodated so as to be movable in the longitudinal direction of the accommodation recesses 48a and 48b (the radial direction of the movable plate 48) in a state in which a part of each of the spheres 53A and 53B protrudes from the accommodation recesses 48a and 48b toward the rotating plate 50. ing.

  As shown in FIG. 28 and FIG. 29, a pair of first recesses 50a, 50b, a pair of second recesses 50c, 50d, and a pair of third recesses 50e are provided on the surface of the rotating plate 50 facing the movable plate 48. , 50f are formed. The first recesses 50a and 50b are arranged symmetrically with respect to the axis of the protruding cylinder part 43c. That is, they are arranged 180 ° apart in the circumferential direction on the circumference centering on the axis of the protruding cylinder portion 43c. The same applies to the second recesses 50c and 50d and the third recesses 50e and 50f. However, the second recesses 50c and 50d are arranged on the radially outer side of the rotating plate 50 from the first recesses 50a and 50b, and the third recesses 50e and 50f have substantially the same diameter as the second recesses 50c and 50d. It is arrange | positioned on the circumference which has. In addition, each of the recesses 50a to 50f is arranged with the following relationship with the spheres 53A and 53B.

  That is, as shown in FIG. 28, it is assumed that the spheres 53A and 53B are positioned so as to be in contact with inclined one end portions of the bottom surfaces of the first concave portions 50a and 50b in the circumferential direction of the rotating plate 50. Hereinafter, the position of the rotation plate 50 and the second connecting arm 51 at this time is referred to as a second rotation start end position. When the rotation plate 50 and the second connecting arm 51 are rotated by a predetermined angle (15 °) in one direction (clockwise in FIG. 25) from the second rotation start end position, the spheres 53A and 53B are moved from the first recesses 50a and 50b. Escape. When the rotation plate 50 is rotated 160 ° from the second rotation start end position, the spheres 53A and 53B are fitted into the third recesses 50e and 50f, respectively. Hereinafter, the position of the rotating plate 50 and the second connecting arm 51 at this time is referred to as a click position. Here, the first recesses 50a and 50b and the third recesses 50e and 50f are separated from each other in the radial direction of the rotating plate 50, but between the first recess 50a and the third recess 50e and between the first recess 50b. And the third recess 50f are formed with spiral guide grooves 50g and 50h for connecting them to each other, so that the spheres 50A and 50B can rotate in one direction of the rotary plate 50. Accordingly, the guide grooves 50g and 50h can roll in the longitudinal direction and enter the third recesses 50e and 50f, respectively. When the rotation plate 50 and the second connecting arm 51 are rotated 180 ° in one direction from the second rotation start end position, the spheres 50A and 50B enter the second recesses 50c and 50d, and the inclined one end (the rotation) of the bottom surface thereof. The moving plate 50 and the second connecting arm 51 are positioned so as to be in contact with the rear end portion in the direction of rotation in one direction. Hereinafter, the position of the rotation plate 50 and the second connecting arm 51 at this time is referred to as a second rotation end position.

  Since the movable plate 48 is urged toward the rotating plate 50 by the coil spring 52, the rotating plate 50 and the second connecting arm 51 are positioned at the second rotation starting end position, and the spheres 53A and 53B are in the first recess. When abutting against one inclined end of the bottom surfaces of 50a and 50b, the urging force of the coil spring 52 is converted into a rotating urging force that rotates the rotating plate 50 and the second connecting arm 51 in the other direction. When the rotating plate 50 and the second connecting plate 51 are located at the click position and the spheres 53A and 53B are fitted in the third recesses 50e and 50f, the rotating plate 50 and the second connecting plate 51 are connected to the coil spring 53. The urging force causes the click position to stop at a predetermined magnitude. When the rotation plate 50 and the second connecting plate 51 are positioned at the second rotation end position and the spheres 53A and 53B are in contact with the inclined other end portions of the bottom surfaces of the second recesses 50c and 50d, the coil spring 53 The urging force is converted into a rotation urging force that rotates the rotation plate 50 and the second connecting arm 51 in one direction.

  As shown in FIG. 9, the hinge device 4 is covered with a decorative cover 54. As a result, the portion of the receiver 3 that has entered the receiving recess 3d cannot be seen from the outside. The decorative cover 54 is disposed so as to straddle the rotating member 43, and is movable with respect to the rotating member 43 in the axial direction of the support cylinder 42. One end and the other end of the cover 54 straddling the rotating member 43 are respectively fixed to one end 44e and the other end 44f of the movable member 44 by screws B4 (see FIG. 10). Therefore, the decorative cover 54 behaves integrally with the movable member 44. That is, the decorative cover 54 moves integrally with the movable member 44 in the axial direction of the support cylinder 42 and rotates integrally with the movable member 44 about the axis line of the support cylinder 42.

  As shown in FIG. 12, when the receiver 3 is located at the folding position, one end 54 a of the decorative cover 54 located on the other end side (left side in FIG. 12) of the transmitter 2 is connected to the receiver 3. The engaging projection 3h formed on the bottom surface of the housing recess 3d is substantially in contact with the surface (the lower surface in FIG. 12) facing the transmitter 2 side. Accordingly, when the movable member 44 moves along the first rotation axis L1 in the direction away from the transmitting portion 2 (mounting plate 41) (upward in FIG. 12), the one end portion 44e of the movable member 44 is engaged with the projecting portion. 3h is pushed in the same direction through one end 54a of the decorative cover 54. As a result, the receiver 3 is rotated in the direction from the second start end position to the second end position (clockwise in FIG. 12) about the second rotation axis L2. Note that the one end 44e of the movable member 44 may be brought into direct contact with the engaging protrusion 3h without the one end 54a of the decorative cover 54 interposed.

  As shown in FIG. 15, when the receiving part 3 is located at the reverse folding position, the other end part (the end part located on the left side in FIG. 15) 54b of the decorative cover 54 is transmitted by the engaging protruding part 3h. It is almost in contact with the surface facing the part 2 side. Therefore, when the movable member 44 moves in the direction away from the transmitting portion 2 along the first rotation axis L1, the other end portion 44f of the movable member 44 moves the engaging protrusion 3h to the other end portion 54b of the decorative cover 54. Press in the same direction through. As a result, the receiver 3 is rotated in the direction from the reverse folding position (second terminal position) to the second starting position about the second rotation axis L2. Also in this case, the other end 44f of the movable member 44 may be brought into direct contact with the engagement protrusion 3h.

  The hinge device 4 configured as described above is attached to the first and second receivers 2 and 3 as follows. That is, as shown in FIG. 11, the mounting plate 41 is inserted into the mounting recess 2b of the transmitter 2, and is fixed by screws B3 (see FIG. 10). In this state, the axis of the support cylinder 42 of the hinge device 4 is aligned with the first rotation axis L1, and the axes of the protruding cylinder portions 43b and 43c are aligned with the second rotation axis L2. In addition, with respect to the first rotation axis L1, the first rotation start position and the first rotation end position of the rotation member 43 and the movable member 44 are respectively the first start position and the first end position of the receiver 3. With respect to the second rotation axis L2, the second rotation start end position, the click position, and the second rotation end position of the second connecting arm 51 correspond to the second start end position, the call position, and the second position of the earpiece unit 3, respectively. The two end positions are matched with each other.

  In the mobile phone 1 in which the transmitter 2 and the receiver 3 are connected via the hinge device 4, when the receiver 3 is located at each of the first start position, the first end position, and the call position, the receiver 3 is fixed (stopped) to the transmitter 2 with a click feeling at each position. When the receiver 3 is located between the second start end position and a position away from the second start end position by a predetermined angle (15 °) toward the second end position, the receiver 3 is centered on the second rotation axis L2. After being rotated to the second start position, the second start position is maintained. Similarly, when the receiver 3 is located between the second end position and a position away from the second end position by a predetermined angle (15 °) toward the second start position, the receiver 3 is centered on the second rotation axis L2. After being rotated to the second terminal position, the second terminal position is maintained.

  When the receiving part 3 located at the folding position rotates from the first starting end position to the first displacement position, the convex parts 41a and 41b of the mounting plate 41 escape from the concave parts 44c and 44d of the movable member 44, respectively. The member 44 comes into contact with the surface facing the mounting plate 41. As a result, the movable member 44 and the decorative cover 54 are moved away from the mounting plate 41 against the biasing force of the coil spring 45. Then, one end portion 54 a of the decorative cover 54 presses the engagement protrusion 3 h of the receiver 3. Thereby, the receiver 3 is rotated from the second start position to the first escape position about the second rotation axis L2. Along with this, the front surface 3 a of the receiver 3 is separated from the front surface 2 a of the transmitter 2. Further, when the receiving portion 3 is rotated from the first displacement position to the first start position, the convex portions 41a and 41b are fitted into the concave portions 44c and 44d, respectively, so that the movable member 44 and the decorative cover 54 are attached to the mounting plate by the coil spring 45. It is moved to the 41 side. As a result, the receiver 3 can be rotated from the escape position to the second start position about the second rotation axis L2, and is rotated to the second start position by the rotation biasing force based on the biasing force of the coil spring 52. Be made. Thus, when the receiver 3 rotates between the first start position and the first displacement position about the first rotation axis L1, the front surface 3a of the receiver 3 is along the first rotation axis L1. Therefore, the operation button 2c provided on the front surface 2a of the transmitter 2 is not touched. Therefore, it is possible to prevent the mobile phone 1 from malfunctioning. As is clear from the above contents, in this embodiment, the convex portions 41 a and 41 b of the mounting plate 41, the concave portions 44 c and 44 d of the movable member 44, one end portion 44 e of the movable member 44, the coil spring 45, and the decorative cover 54 The first rotation displacement mechanism (first separation rotation mechanism, first approach rotation) is generated by the conversion mechanism that converts the urging force of the one end 54a and the coil spring 52 into the rotation urging force and the engagement protrusion 3h of the receiver 3. Mechanism) 5 is configured.

  When the receiver 3 rotates between the first displacement position and the second displacement position about the first rotation axis L1, the convex portions 41a and 41b are opposed to the mounting plate 41 of the movable member 44. Slide on the surface. At this time, since the facing surface is a plane orthogonal to the first rotation axis L1, the receiver 3 moves the second rotation axis L2 along with the rotation about the first rotation axis L1. The first escape position (second escape position) is maintained without rotating around the center. Further, when the receiver 3 rotates between the second displacement position and the first terminal position about the first rotation axis L1, the first rotation displacement mechanism 5 causes the second rotation axis L2 to move. The center is rotated between the second starting end position and the second escape position.

  When the receiving portion 3 located at the reverse folding position rotates from the first terminal position to the third displacement position about the first rotation axis, the convex portions 41a and 41b of the mounting plate 41 become the concave portions of the movable member 44. It escapes from 44d and 44c, respectively, and comes to contact the opposing surface with the mounting plate 41 of the movable member 44. FIG. As a result, the movable member 44 and the decorative cover 54 are moved away from the mounting plate 41 against the biasing force of the coil spring 45. Then, the other end portion 54 b of the decorative cover 54 presses the engagement protrusion 3 h of the receiver 3. Thereby, the receiver 3 is rotated from the second terminal position to the third escape position about the second rotation axis L2. Along with this, the back surface 3 g of the receiver 3 is separated from the front surface 2 a of the transmitter 2. Further, when the receiver 3 is rotated from the third displacement position to the first terminal position, the convex portions 41a and 41b are fitted into the concave portions 44d and 44c, respectively, so that the movable member 44 and the decorative cover 54 are attached to the mounting plate by the coil spring 45. It is moved to the 41 side. As a result, the receiver 3 can rotate from the third escape position to the second end position about the second rotation axis L2, and to the second start position by the rotation biasing force based on the biasing force of the coil spring 52. It can be rotated. Thus, when the receiver 3 rotates between the first terminal position and the third displacement position about the first rotation axis L1, the back surface 3g of the receiver 3 is along the first rotation axis L1. Therefore, the operation button 2c provided on the front surface 2a of the transmitter 2 is not touched. Therefore, it is possible to prevent the mobile phone 1 from malfunctioning. As apparent from the above contents, in this embodiment, the convex portions 41a and 41b of the mounting plate 41, the concave portions 44d and 44c of the movable member 44, the other end portion 44f of the movable member 44, the coil spring 45, and the decorative cover 54 are provided. The second rotation displacement mechanism (second separation rotation mechanism, second approach) by the other end portion 54b of the coil, the conversion mechanism for converting the urging force of the coil spring 52 into the rotation urging force, and the engagement protrusion 3h of the receiver 3. (Rotating mechanism) 7 is configured.

  When the receiver 3 rotates between the third displacement position and the fourth displacement position about the first rotation axis L1, the second displacement mechanism 7 causes the third escape position (fourth relief position) to rotate. Position), and when rotating between the fourth displacement position and the first start position about the first rotation axis L1, the second rotation displacement mechanism 7 causes the second rotation axis L2 to be centered. The second end position and the fourth escape position are rotated.

In addition, this invention is not limited to said embodiment, In the range which does not deviate from the summary, it can change suitably.
For example, in the above-described embodiment, the first and second rotational displacement mechanisms 5 and 7 center the second rotational axis L2 as the receiver 3 is pivoted about the first rotational axis L1. However, the receiver 3 may be moved along the first rotation axis L1.
