In conventional mobile phones, the transmitter and receiver have only rotated about one rotation axis. Recently, however, as disclosed in Japanese Patent Laid-Open No. 2 00 2-2 0 9 0 0 0, the transmitting unit and the receiving unit are centered on two rotation axes that are orthogonal to each other. A mobile phone that is pivotally connected is provided. In such a cellular phone, one end portion of a connecting shaft having a circular cross section is provided at one end portion on the receiving portion side of the transmitting portion so as to be rotatable about its axis (first rotation axis). The other end of this union shaft protrudes from the front surface of the transmitter. On the other hand, a recess is formed at one end of the receiver on the transmitter side. End portions projecting from the transmitting portion of the connecting shaft are inserted into the concave portions. Arm portions are formed on both end faces of the concave portion facing the connecting shaft. Each arm is connected to a disjoint shaft so as to be rotatable about a second rotation axis perpendicular to the first rotation axis. As a result, the transmitter and receiver are coupled so as to be rotatable about two rotation axes that are orthogonal to each other (see, for example, Patent Document 1).

Hereinafter, embodiments of the present invention will be described with reference to FIGS.

1 to 43 show an embodiment of the present invention. In this embodiment, this invention is applied to a mobile phone (mobile device) 1. First, the general configuration of the mobile phone 1 will be described. The mobile phone 1 includes a transmitter (main body) 2 and a receiver (turning). Part) 3 and 4 connecting members. The transmitter 2 has a substantially rectangular parallelepiped shape with a small thickness, and various operation buttons 2 b are provided on the front surface 2 a. The receiver 3 also has a substantially rectangular parallelepiped shape with a small thickness, and a liquid crystal display 3 b is provided on the front surface 3 a. The width of the receiver 3 is set to be the same as the width of the transmitter 2. The connecting member 4 is connected to one end of the transmitter 2 on the receiver 3 side so as to be rotatable about a first rotation axis (rotation axis) L1 orthogonal to the front surface 2a. 3 is connected to one end of the transmitter 2 side so as to be rotatable about a second rotation axis L 2 orthogonal to the first rotation axis L 1. Thereby, the transmitter 2 and the receiver 3 are connected so as to be rotatable about the first and second rotation axes L 1 and L 2.

Next, the rotation mode of the transmitter 2 and the receiver 3 will be described. For convenience of explanation, it is assumed that the transmitter 2 is fixed and the receiver 3 rotates with respect to the transmitter 2. .

FIG. 1 shows a state in which receiver 3 is in the original position with respect to transmitter 2. When the receiver 3 is in its original position, the center of the receiver 3 in the second rotation axis L 2 direction coincides with the center of the transmitter 2 in the same direction, and as a result, both sides of the receiver 3 are It is located on the same plane as both sides of transmitter 2. In the original position, the front surface 3 a of the receiver 3 is in contact with the front surface 2 a of the transmitter 2. The position in the circumferential direction around the first rotation axis L 1 of the receiver 3 when both sides of the receiver 3 are on the same plane as both sides of the transmitter 2 is the initial position. . The position in the circumferential direction around the second rotation axis L 2 of the receiver 3 when the front surface 3 a of the receiver 3 is in contact with the front surface 2 a of the transmitter 2 is the folding position. Therefore, the original position is the position of the receiving unit 3 when the receiving unit 3 is located at the initial position and the folding position.

As shown in FIGS. 2 to 4, the receiver 3 can be rotated by a predetermined range in the forward and reverse directions around the first rotation axis L 1. In the case of this embodiment, the receiver 3 can be rotated approximately 180 degrees from the initial position in one direction indicated by an arrow in FIG. 2, FIG. 3, FIG. 32, and FIG. The position of the receiving unit 3 when the receiving unit 3 is rotated approximately 180 ° from the initial position is the first rotation limit position. On the other hand, the receiver 3 can be rotated approximately 90 ° from the initial position in the other direction indicated by the arrow in FIGS. 4 and 36. Earpiece The position of the receiver 3 when 3 is rotated approximately 90 ° from the initial position is the second rotation limit position. Therefore, the pivotable range of the receiver 3 around the first pivot axis L 1 is approximately 2700 °. The receiver 3 rotates integrally with the connecting member 4 when rotating around the first rotation axis L 1. Therefore, each rotation position around the first rotation axis L 1 of the connecting member 4 is referred to as the rotation position of the receiver 3. '·

As can be seen by comparing FIG. 1 to FIG. 4 and FIG. 5 to FIG. 12, the earpiece 3 can be located at any position within the rotatable range. 3 A second rotation between the folding position where a hits the front 3 a of the transmitter 2 and the rear position 3 c of the receiver 3 hits the front 2 a of the transmitter 2 It can be rotated around the axis L 2. In this embodiment, the angle between the folding position and the unfolded position is set to approximately 180 °.

Next, a more detailed configuration of the mobile phone 1 will be described. As shown in FIGS. 13 to 15, the transmitter 2 is divided into two parts divided into two in the first rotation axis L 1 direction. Therefore, it is configured. One part is a front part 2A including a front face 2a, and the other part is a back part 2B including a rear face 2c (see FIGS. 14 and 15). The front part 2A and the back part 2B are abutted with each other in the direction of the first rotation axis L1 and are fixed by bonding or other fixing means, whereby the transmission part 2 is configured. As shown in FIGS. 13 and 15, a support hole 2 d penetrating through the wall portion having the front surface 2 a is formed at the end portion of the front portion 2 A on the receiver 3 side. The support hole 2 d is located at the center of the main body 2 in the direction of the second rotation axis L 2, and is arranged so that its axis is aligned with the first rotation axis L 1. As shown in FIGS. 15 and 30 to 37, a notch 2e extending in the circumferential direction is formed at the end on the front surface 2a side of the inner peripheral surface of the support hole 2d. The circumferential length of the notch 2e is set to be slightly longer than the rotatable range (270 °).

As shown in FIG. 13 to FIG. 15, the receiver 3 is composed of two parts divided into two in the first rotation axis L 1 direction. One part is the front part 3A including the front surface 3a, and the other part is the back part 3B including the back surface 3c. The front part 3 A and the back part 3 B are set to have the same thickness (thickness in the first rotation axis L 1 direction). Yes. Then, the front part 3 A and the back part 3 B are abutted against each other in the direction of the first rotation axis L, and are fixed by bonding or other fixing means, whereby the receiving part 3 is configured. A concave portion 3 d extending from the front surface 3 a to the back surface 3 c is formed at the end of the receiver portion 3 on the transmitter portion 2 side. The recess 3 d is disposed at the center of the receiver 3 in the second rotation axis L 2 direction. As shown in FIGS. 15 and 38 to 40, receiving holes 3 e having a long hole shape in cross section are formed on both end surfaces of the recess 3 d in the second rotation axis L 2 direction. The receiving hole 3 e is arranged so that its axis coincides with the second rotation axis L. As shown in Fig. 1 to Fig. 1 2 and Fig. 14, both sides 3 f and 3 f adjacent to the recess 3 d at the end of the receiving part 3 on the transmitting city 2 side are semicircular in cross section. Is formed. The center of curvature of the arc surface that forms the outer surface of the side portion 3 f is arranged on the second rotation axis L 2. As a result, when the receiving unit 3 rotates about the second rotation axis L 2, both sides 3 f and 3 f of the end of the receiving unit 3 on the transmitting unit 2 side are in front of the transmitting unit 2. 2 The fold between the folded and unfolded positions can be rotated without interfering with a (see Fig. 38 to Fig. 40).

As shown in FIGS. 20 to 25, the connecting member 4 has a disc portion 4a. An engagement protrusion 4 b is formed on the peripheral edge portion of the lower surface of the disc portion 4 a in FIGS. 20 and 21. A shaft portion 4c is formed integrally with the disc portion 4a at the center of the lower surface of the disc portion 4a. The shaft portion 4 c has a substantially cylindrical shape by forming a hole 4 d extending upward from the lower end surface to the base end portion. The shaft portion 4 c may be formed solid. On the outer peripheral surface of the base end portion of the shaft portion 4c, a pair of key portions 4e and 4eS are disposed and formed at a distance of 180 ° in the circumferential direction. On the upper surface of the disc portion 4a, a support portion 4 ί is formed integrally with the disc portion 4a. The support portion 4 f has a connecting shaft portion 4 g at its upper end. The connecting shaft portion 4 g is arranged so that the axis thereof is orthogonal to the axis of the disc portion 4 a and the shaft portion 4 c. The length of the connecting shaft portion 4g is longer than the outer diameter of the disc portion 4a, and both end portions thereof protrude outward from the outer periphery of the disc portion 4a. Both end portions of the connecting shaft portion 4 g protruding from the disc portion 4 a have a circular cross section. The intermediate part of the connecting shaft part 4 g has a semicircular cross section, and is smoothly connected to the upper surface of the disk part 4 a via a parallel part 4 h and an arc part 4 j. Attachment holes 4 i extending on the axis are formed on both end faces of the connecting shaft portion 4 g. As shown in FIG. 15, a hinge device (third hinge) 5 is provided inside the transmitter 2. The hinge device 5 is arranged such that its axis coincides with the first rotation axis L 1. Then, the connecting member 4 is supported by the transmitting part 2 through the hinge device 5 so as to be rotatable about the first rotation axis L, and as a result, the receiving part 3 is supported by the transmitting part 2 on the first rotation axis L. It is supported so as to be rotatable about 1.

As shown in FIGS. 15 to 19, the hinge device 5 has a first hinge member 51. The first hinge member 51 has a disc portion 51a. At the center of the lower surface of the disk part 5 la in Fig. 18 (the surface facing the back 2 c side of the transmitter 2), the fitting shaft part 5 1 b with a circular cross-section is integrated with the disk part 5 1 a. Is formed. A key groove 51c extending from the base end portion to the tip end portion is formed on the outer peripheral surface of the fitting shaft portion 51b. A through hole 5 1 d penetrating them is formed in the central portion of the disc portion 5 1 a and the fitting shaft portion 5 1 b. A pair of key grooves 51 e, 51 e are disposed and formed at a distance of 180 degrees in the circumferential direction at the intersection between the inner peripheral surface of the through hole 51 d and the upper surface of the disc portion 51 a. ing. A pair of disc springs 5 2 and '5 2, a movable member 5 3, a second hinge member 5 4, a spacer 5 5 and a stopper 5 6 are extrapolated in this order on the fitting shaft 5 1 b. Has been. The disc spring 52 has a tapered shape, and its outer diameter is substantially the same as the outer diameter of the disc portion 51a of the first hinge member 51. The movable member 5 3, the second hinge member 5 4, the spacer 5 5 and the stopper 5 6 are all disk-shaped, and their outer diameter is almost the same as the outer diameter of the disk portion 5 1 a. It is the same. The stopper 56 is fixed to the tip end (lower end) of the fitting shaft portion 51b. As a result, the disc springs 5 2 and 5 2, the movable member 5 3, the second hinge member 5 4, and the spacer 5 5 are prevented from coming down downward from the fitting shaft portion 5 1 b, and the entire hinge device 5 is united. (Integrated).

A pair of attachment plate portions 5 4 a is formed on the outer peripheral portion of the second hinge member 54. The mounting plate portion 5 4 a is fixed to the inner surface of the wall portion having the front surface 2 a of the transmission portion 2 by screws B. As a result, the hinge device 5 is attached to the transmitter 2. In this case, the hinge device 5 is attached in a state where the first hinge member 51 is positioned on the front surface 2a side and the axis thereof is coincident with the first rotation axis L1. Accordingly, the first and second hinge members 51, 54 and the movable member 53 also have their axes aligned with the first rotation axis L1. The movable member 53 has a key portion 53a formed on the inner peripheral surface thereof that fits into the key groove 51c so that the movable member 53 cannot rotate on the outer periphery of the fitting shaft 51b, and the axial direction ( It is fitted so that it can move in the first rotation axis (L direction). Therefore, the movable member 53 rotates integrally with the first hinge member 5 ί. The movable member 53 is biased toward the second hinge member 54 by the disc spring 52.

A pair of spheres (protrusions) 57 Α and 57 可能 can be rotated on the end surface of the movable member 53 facing the second hinge member 54 with some of them protruding toward the second hinge member 54. It is buried in. The pair of spheres 57Α and 57Β are arranged 180 ° apart on one circumference centered on the first rotation axis L1. On the other hand, a pair of recesses 54 b and 54 c are formed on the end surface of the second hinge member 54 facing the movable member 5.3. The pair of recesses 54 b and 54 c are arranged 180 ° apart on a circle having the same diameter as the circle in which the spheres 57 A and 57 B are arranged with the first rotation axis L 1 as the center. ing. Therefore, when the first hinge member 51 and the movable member 53 rotate, the spheres 57A and 578 enter and exit the recesses 54 and 54c. In this case, when the movable member 53 is rotated to a predetermined position (the initial position of the receiver 3), the spheres 57A and 57B are fitted into the recesses (first recesses) 54b and 54c, respectively, and the first hinge member When 5 1 is rotated 180 ° away from the specified position (turning position of receiver 3), spheres 57A and 57B are fitted into recesses (second recesses) 54c and 54b, respectively.

When the spheres 57A and 578 are fitted in the recesses 54 3 and 54 c (54 c and 54 b), the movable member 53 and the second hinge of the first hinge member 51 are moved by the biasing force of the disc spring 52. The rotation with respect to the member 54 is prevented by a predetermined amount of force. The first hinge member 51 is in position and 180 from there. When positioned at a position other than the separated position, the spheres 57A and 57B roll on the end surface of the second hinge member 54. At this time, rolling friction resistance is generated between the spheres 57A and 57B and the second hinge member 54, and sliding friction resistance is generated between the spheres 57A and 57B and the movable member 53. . These frictional resistances allow the first hinge member 51 to stop at an arbitrary position with respect to the second hinge member 54. The details of the positional relationship between the spheres 57 A and 57 B and the recesses 54 b and 54 c and the receiver 3 will be described later. For the spheres 5 7 A and 5 7 B, instead of them, for example, spherical projections may be formed. Also, the spheres 5 7 A and 5 7 B are provided on the second hinge member 5 4, and the recess 5

4 b and 5 4 c may be provided on the movable member 53. In addition, a pair of recesses 5 4 b and 5 4 c are 1 80. Since the pair of recesses 5 4 b and 5 4 c are used as the first recess and the second recess, the pair of recesses 5 4 b and 5 4 c are used as the first recess. For example, a pair of recesses may be formed at a position inclined by 90 ° with respect to the first recesses 5 4 b and 5 c, and the pair of recesses may be used as the second recess.

As shown in FIG. 15, the disk portion 4 a of the connecting member 4 is inserted into the support hole 2 d from the opening on the front surface 2 a side, and the first of the hinge device 5 is inserted through the spacer S. It hits the hinge member 51. In this state, the upper surface of the disc portion 4a in FIG. 15 is located on the same plane as the front surface 2a. In addition, since the disc portion 4a is fitted into the support hole 2d with almost no gap, it is possible to reduce the reduction in appearance due to the formation of the support hole 2d. Note that the upper surface of the disc portion 4a may slightly protrude from the front surface 2a.

The shaft portion 4 c of the union member 4 is inserted into the through hole 51 d of the first hinge member 51 of the hinge device 5 with almost no gap. The tip of the shaft 4c passes through the through hole 51d and protrudes downward in Fig. 15 where there is a retaining ring consisting of a C ring or E ring: R hits the stopper 56. It is fixed in the state. The retaining ring R abuts against the stock 56 and the disc portion 4 a abuts against the first hinge member 51 via the spacer S, whereby the connecting member 4 contacts the hinge device 5 with the first rotation axis L. It is attached so that it cannot move in one direction, and by extension, it is attached to the transmitter 2 so that it cannot move in the first rotation axis L1 direction. '

A pair of key portions 4 e and 4 e formed on the disc portion 4 a of the connecting member 4 are fitted in the pair of key grooves 51 and 51 respectively of the first hinge member 51. As a result, the connecting member 4 is connected to the first hinge member 51 so as not to rotate. As a result, the receiver 3 is connected to the transmitter 2 via the hinge device 5 so as to be rotatable about the first rotation axis L 1.

The rotation range around the first rotation axis L 1 with respect to the transmitter 3 of the receiver 3 and the connecting member 4 is restricted to a predetermined range. That is, as shown in Figure 30 to Figure 37 In addition, the engaging protrusion 4 b formed on the disk portion 4 a of the connecting member 4 enters the notch 2 e formed on the inner peripheral surface of the support hole 2 d so as to be movable in the longitudinal direction. . The engaging protrusion 4 b abuts against one end 2 f or the other end 2 _g of the notch 2 e, thereby restricting the rotation range of the connecting member 4 relative to the transmitter 2. As shown in FIG. 35, the positions of the receiving part 3 and the connecting member 4 when the engaging protrusion 4b hits the one end 2f of the notch 2e are the first rotation limit positions. As shown, the position of the earpiece 3 and the connecting member 4 when the engagement protrusion 4b hits the other end 2g of the notch 2.e is the second rotation limit position. The range between the first rotation limit position and the second rotation limit position is the range in which the earpiece 3 and the connecting member 4 can rotate. As will be apparent from this, in this embodiment, the notch portion 2 e and the engagement protrusion 4 b constitute the rotation range restricting mechanism 6.

As shown in FIG. 30 and FIG. 31, when the receiver 3 is in the initial position, the engaging protrusion 4 b is separated from the one end 2 f of the notch 2 e by approximately 180 ° in the circumferential direction. positioned. In other words, the initial position of the receiver 3 is a position that is approximately 180 ° away from the first rotation limit position. At this time, the spheres 57A and 57B enter the recesses 54b and 54c, respectively. Therefore, when the reception unit 3 is located at the initial position, the rotation of the reception unit 3 around the first rotation axis L 1 with respect to the transmission unit 2 is blocked with a predetermined amount of force. . As is clear from this, the first click mechanism K 1 is configured by the spheres 5 7 A and 5 7 B and the recesses (first recesses) 54 b and 54 c.

As shown in Fig. 34 and Fig. 35, when receiver 3 rotates 18'0 ° in the direction of the arrow from the initial position, spheres 57 A and 578 enter recesses 54 (and 54 b, respectively. The turning position of the portion 3 is the turning position, and therefore, even in the turning position, the receiving portion 3 is prevented from turning about the first turning axis L 1 with a predetermined amount of force. Therefore, the spheres 57A and 57B and the concave portions (second concave portions) 54c and 54d constitute the second tallic mechanism K 2. When the receiving portion 3 reaches the turning position, the engaging portion 4b is cut off. The force that hits one end 2 f of the notch 2 e \ Just before it is reached That is, in this embodiment, the turning position and the first turning limit position are set at almost the same position. The receiver 3 starts from the turning position as shown in FIG. It is almost impossible to rotate in the direction of the arrow. Of course, if the turning position is within the range between the first rotation limit position and the second rotation limit position, it may be set at a location away from the first rotation limit position to the second movable limit position side. Good.

As shown in FIGS. 3 2, 3 3, 3 6 and 3 7, the receiver 3 is located at a position other than the initial position and the turning position within the first and second rotation limit positions. At this time, ί OBDA 5 7 A, 5 7: 8 comes out of the recesses 5 4 13, 5 4 c and rolls on the surface of the second hinge member 5 4 facing the movable member 5 3. Therefore, at such a position, the receiving section 3 can be stopped at an arbitrary position by the frictional resistance generated in the hinge device 5.

As shown in FIGS. 1 to 12, 15, and 38 to 40, the support portion 4 f of the connecting member 4 is inserted into the recess 3 d of the receiver 3. Here, the length of the support portion 4 f in the second rotation axis L 2 direction is substantially equal to the length of the recess portion 3 d in the same direction, and the height of the support portion 4 f from the front surface 2 a is approximately the recess portion 3 f. It is almost equal to the depth of d (the depth in the direction from the one end side to the other end side of the receiver 3). Therefore, the receiver 3 is connected to the connecting member 4 so as to be rotatable about the second rotation axis L 2 (the axis of the mounting hole 4 i formed on both end surfaces of the support 4 f and the recess 3 d In a state in which the axes of the receiving holes 3 e formed on both end faces are aligned with each other, almost no gap is formed between each part of the recess 3 d and each part of the support part 4 f. This improves the aesthetics of the cellular phone 1.

In particular, in this embodiment, as shown in FIG. 39, the width of the parallel part 4 h of the support part 4 ί is set to be substantially the same as the thickness of the receiver part 3, and FIG. As shown in 40, the radius of curvature of the connecting shaft 4g is almost the same as the radius of curvature of the side 3f of the receiver 3. Further, on both sides of the base portion of the support portion 4 f, arc portions 4 j that smoothly connect the parallel portions 4 h and the disc portions 4 a are formed, and arcs are formed on both sides of the bottom surface of the recess 3 d. A circular arc portion 3 h corresponding to the portion 4 j is formed. By adopting these configurations, the aesthetic appearance of the mobile phone 1 is further improved. Both end portions of the connecting shaft portion 4 g of the connecting member 4 are rotatably connected to the receiver portion 3 via hinge devices (first and second hinges) 7, 7. Of course, the hinge devices 7 and 7 have their axes aligned with the second rotation axis L. Therefore, connecting member 4 and receiver 3 is connected to be rotatable about the second rotation axis L. As for one of the two hinge devices 7, a simple shaft body may be used instead. In such a case, the shaft body may be formed integrally with one of the connecting member 4 and the receiving portion 3 and may be rotatably fitted to the other.

As shown in FIGS. 26 to 29, the hinge device 7 includes first and second hinge members 7 1 and 7 2 that are arranged with their respective axes aligned with the second rotation axis. Yes.

The first hinge member 71 is rotatably fitted to the outer periphery of one end of the hinge shaft 73, and hits the head 7 3a formed at one end of the hinge shaft 73 so that the hinge shaft 7 3 is secured from one end. The second hinge member 72 is non-rotatably fitted to the outer periphery of the other end of the hinge shaft 73, and the other end of the hinge shaft 73 passing through the second hinge member 72 is shown in FIG. As shown by the imaginary line, it is prevented from coming off from the other end of the hinge shaft 73 by crimping.

As shown in FIG. 15, the first hinge member 71 is non-rotatably fitted in the mounting hole 4 i of the connecting member 4, and the second hinge member 7 2 is the receiving hole 3 of the receiver 3. It is non-rotatably fitted to e. As described above, the first and second hinge members 7 1 and 7 2 are rotatably connected via the hinge shaft 73. Therefore, the receiver 3 is connected to the connecting member 4 via the first and second hinge members 7 1 and 7 2 and the hinge shaft 7 3 so as to be rotatable about the second rotation axis L 2. .

On the outer periphery of the hinge shaft 7 3 positioned between the first and second hinge members 7 1 and 7 2, a movable member 74 is fitted so as to be movable in the second rotation axis L direction. The movable member 74 is connected to the first hinge member 71 so as not to be rotatable and movable in the direction of the second rotation axis L2. The movable member 74 is biased toward the second hinge member 72 by a coil spring (biasing means) 75. Between the movable member 74 and the second hinge member 72, a pair of spheres 76A and 76B are arranged.

Here, of the bottom surfaces of the first recesses 72a and 72b, the locations where the spheres 76A and 76B abut when the receiver 3 is in the folded position are inclined toward the circumferential direction. Yes. Therefore, when the spheres 7 6A and 7 6 B are pressed against the bottom surfaces of the first recesses 7 2 a and 72 b by the coil springs 75, the urging force of the coil springs 75 is converted into rotational urging forces. The second urging member 72 is urged to rotate in the direction of the arrow in FIG. 42 by this urging force, and the receiver 3 is further rotated from the unfolded position side to the folded position side via the second hinge member 72.

Here, of the bottom surfaces of the second recesses 7 2 c and 7 2 d, the locations where the spheres 76A and 7 6 B abut when the receiver 3 is in the deployed position are inclined in the circumferential direction. ing. But Thus, when the spheres 7 6 A and 7 6 B are pressed against the bottom surfaces of the second recesses 7 2 c and 7 2 by the coil springs 75, the urging force of the coil springs 75 is converted into a rotating urging force. The second urging member 72 is urged to rotate in the direction of the arrow in FIG. 43 by this turning urging force, and the receiver 3 is further rotated from the folding position side to the unfolded position side via the second hinge member 72. It is energized. As a result, the back surface 3 c of the receiver 3 is kept in contact with the front surface 2 a of the transmitter 2. That is, the receiver 3 is maintained in the deployed position. As will be apparent, the second rotating biasing means F 2 is formed by the spherical body 7 6 Α, '7 6 Β, the bottom surfaces of the second part 7 2 c, 7 2 d and the coil spring 75.
