The best mode for carrying out the present invention will be described below with reference to the drawings.
1 and 2 show a mobile phone (portable device) A provided with a hinge device 1 according to an embodiment of the present invention. The mobile phone A has a transmitting side housing (first housing) B and a receiving side housing (second housing) C. The receiver-side casing C is connected to the transmitter-side casing B by the hinge device 1 so as to be rotatable around first and second rotation axes L1 and L2. The first rotation axis L1 is parallel to the front surface Ba on which operation buttons (not shown) and the like of the transmission side housing B are provided, and extends in the width direction of the front surface Ba. The second rotation axis L2 is disposed so as to be orthogonal to the first rotation axis L1. As long as the 2nd rotation axis L2 is extended in the direction orthogonal to the 1st rotation axis L1, you may arrange | position away from the 1st rotation axis L1.

  A rotation range around the first rotation axis L1 of the reception-side casing C is limited between the folding position (see FIG. 1) and the call position. The folding position is determined by the front surface Ca of the reception side housing C provided with a liquid crystal display unit (not shown) abutting the front surface Ba of the transmission side housing B. The call position is determined by the rear surface Cb of the receiving side housing C abutting against the inclined surface Bb of the transmitting side housing B. A rotation range around the second rotation axis L2 of the reception-side casing C is determined by the hinge device 1, and the second rotation of the reception-side casing C when located at the folding position. Assuming that the position centered on the axis L2 is the initial position, the initial position is limited to a range of approximately 180 ° in the forward and reverse directions. However, the receiving side case C can be rotated 180 ° in the forward and reverse directions because the receiving side case C is rotated 90 ° from the folding position toward the talking position about the first rotation axis L1. Only the moved position (hereinafter referred to as the upright position) and its vicinity, and at other positions, a part of the receiving side casing C collides with the transmitting side casing B, so that it rotates only within a range of 180 ° or less. It cannot be moved, and cannot be rotated at all at the folding position or the call position.

  Next, a description will be given of the hinge device 1 for connecting the transmitting side case B and the receiving side case C of the mobile phone A so as to be rotatable. The hinge device 1 relates to the first aspect of the present invention, and has a hinge body 2 as shown in FIGS. The hinge body 2 is made of a metal plate or a hard resin plate, and has a flat base portion 2a and a pair of upright plate portions 2b and 2c that stand up at substantially right angles from both ends of the base portion 2a in the same direction. And have.

  An attachment member 3 is rotatably attached to one upright plate portion (left upright plate portion in the figure) 2b via a connecting cylinder 4 and a collar 5. An attachment member 6 is rotatably attached to the other upright plate portion 2 c via a shaft body 7 and a cylinder body 8. The rotation axis of the attachment member 3 and the rotation axis of the attachment member 6 are made to coincide with each other. The attachment members 3 and 6 are attached to the transmission-side casing B in a state in which their rotation axes coincide with the first rotation axis L1. Thereby, the hinge main body 2 is attached to the transmission side housing | casing B so that rotation is possible centering | focusing on the 1st rotation axis L1.

  A first click mechanism 9 is provided between the upright plate portion 2 c and the attachment member 6. The first click mechanism 9 is configured in the same manner as a known one. Therefore, the first click mechanism 9 will be briefly described. The first click mechanism 9 includes the cylinder 8, the movable member 10, the coil spring 11, and a pair of spheres 12 and 12. The cylindrical body 8 is connected to the upright plate portion 2c so as to be rotatable about the first rotation axis L1, and is connected to the mounting member 6 so as not to be rotatable. A movable member 10 is provided at the end of the cylindrical body 8 on the upright plate portion 2c side so as not to be rotatable and movable in the direction of the first rotation axis L1. The movable member 10 is biased toward the upright plate portion 2 c by a coil spring 11 accommodated in the cylindrical body 8. A pair of recesses 10a is formed on the surface of the movable member 10 facing the upright plate portion 2c. The pair of recesses 10a are arranged 180 degrees apart in the circumferential direction on one circumference centered on the first rotation axis L1. In each recess 10a, a sphere 12 is provided in a state in which a part thereof protrudes toward the upright plate portion 2c. The spherical body 12 is pressed against the surface of the upright plate portion 2c facing the movable member 10 by the biasing force of the coil spring 11. On the other hand, a plurality of engaging recesses (not shown) are formed on the surface of the upright plate portion 2c facing the movable member 10. The engaging recess is arranged so that the spherical body 12 fits into the engaging recess when the attachment member 6 rotates with respect to the hinge body 2 about a first rotation axis L1 to a predetermined position. Then, when the spherical body 12 is fitted into the engaging recess by the biasing force of the coil spring 11, the rotation of the hinge body 2 is prevented by a predetermined force. In particular, in this embodiment, as will be described later, the hinge body 2 is connected to the receiving side housing C so that the hinge body 2 and the receiving side housing C rotate integrally around the first rotation axis L1. When the receiving housing C is attached to the folding position, the upright position, or the talking position around the first rotation axis L1, the receiving housing C rotates at a predetermined size at each position. It is blocked by the power of.

  A through hole 2d is formed at the center of the base 2a of the hinge body 2 in the longitudinal direction (the first rotation axis L1 direction). The through hole 2d is arranged so that its axis is orthogonal to the first rotation axis L1, and the axis of the through hole 2d is made to coincide with the second rotation axis L2. The hinge shaft 13 is inserted into the through hole 2d so as to be rotatable and movable. The rotation axis of the hinge shaft 13 is also matched with the second rotation axis L2. The hinge shaft 13 is formed to be hollow in order to insert electric wiring therein. If it is not necessary to insert the wiring, the hinge shaft 13 may be formed solid. One end of the wiring is connected to an electronic device (not shown) provided in the receiver-side casing C, and the other end passes through the connecting cylinder 4 from the left side in FIG. 13 passes downward and is connected to an electronic device provided in the transmission-side casing B. A flange portion 13a is formed at one end portion of the hinge shaft 13 (the upper end portion in FIGS. 6 to 8). When the flange portion 13a abuts against the base portion 2a, the hinge shaft 13 is directed from the one end side to the other end side of the hinge shaft 13 with respect to the hinge body 2 (hereinafter referred to as a first direction. Also, opposite to the first direction. The direction is referred to as the second direction).

  A connecting member 14 is fixed to the other end portion of the hinge shaft 13. A collar 15 is fitted on the outer periphery of the hinge shaft 13 between the connecting member 14 and the base 2a. The collar 15 maintains a predetermined distance between the base portion 2a and the connecting member 14. The connecting member 14 is attached to the receiving case C. As a result, the receiver-side casing C is connected to the hinge body 2 via the connecting member 14 and the hinge shaft 13 so as to be rotatable about the second rotation axis L2, and as a result, the transmitter-side casing B is connected to the transmitter-side casing B with the first, The second pivot axes L1 and L2 are connected so as to be pivotable.

  A second click mechanism (click mechanism) 16 is provided between the hinge body 2 and the hinge shaft 13. When the receiving side casing C rotates about the second rotation axis L2, the second click mechanism 16 rotates when the receiving side casing C is rotated to a folding position or a position 180 ° away from it in the forward and reverse directions. This is intended to prevent the reception-side casing C from rotating with a predetermined amount of force at each position, and is configured as follows.

  In other words, an annular raceway plate (receiving member) 17 is fitted to one end of the hinge shaft 13 that protrudes from the through hole 2d in the second direction so as not to rotate. The raceway plate 17 is fitted to the hinge shaft 13 so as to be movable in the axial direction, but is prevented from moving in the first direction by abutting against the flange portion 13a of the hinge shaft 13. The movement of the raceway plate 18 in the second direction is prevented by a biasing force of a leaf spring 22 described later. Therefore, the track plate 17 does not substantially move in the axial direction of the hinge shaft 13. In addition, the movement of the hinge shaft 13 in the second direction is substantially prevented by the leaf spring 22 by pressing the raceway plate 17 against the flange portion 13a.

  A surface facing the second direction of the track plate 17 (a front surface facing the same direction as the direction from the other end portion of the hinge shaft 13 to the one end portion) is a track surface 17a. The track surface 17a is configured by a plane orthogonal to the second rotation axis L1, and extends in a ring shape around the second rotation axis L1. On the raceway surface 17a, two engaging recesses (engaged portions) 17b and 17c are formed. The engaging recesses 17b and 17c are formed as grooves extending from the inner peripheral surface to the outer peripheral surface on the diameter line of the raceway plate 17, but may be formed as circular or other concave portions. Further, only one of the engagement recesses 17b and 17c may be formed, or three or more may be formed. Furthermore, although the engagement recessed parts 17b and 17c are arrange | positioned at equal intervals in the circumferential direction of the track board 17, you may arrange | position at an equal interval in the circumferential direction.

  A holding member 18 having a plate shape is placed on the surface of the base portion 2a facing the second direction. The holding member 18 is disposed on the upright plate portion 2c side, but may be disposed on the upright plate portion 2b side. The holding member 18 is positioned by a positioning member 19 fixed to the base portion 2a. In addition, the holding member 18 is fixed to the base portion 2 a by a bolt 20 that passes through an end portion spaced from the raceway plate 17 in the radial direction of the hinge shaft 13. The end of the holding member 18 on the hinge shaft 13 side is disposed in front of the track plate 17 in the second direction and faces the track surface 17a. A holding hole 18 a penetrating the end portion along the hinge shaft 13 is formed at an end portion of the holding member 18 facing the raceway surface 17 a. The end of the holding hole 18a in the first direction is opened to the outside via a notch 18b formed on the end surface of the holding member 18 facing the hinge shaft 13.

  A spherical body (engaging member) 21 is inserted into the holding hole 18a. The spherical body 21 has substantially the same outer diameter as the inner diameter of the holding hole 18a. Accordingly, the sphere 21 can move in the longitudinal direction of the holding hole 18a (the second rotation axis L2 direction), but cannot move in the circumferential direction around the second rotation axis L2. An end portion of the sphere 21 located in the front in the first direction protrudes to the outside from the holding hole 18a through the notch portion 18b and is in contact with the track surface 17a. In addition, the end of the sphere 21 fits into one of the two engaging recesses 17b and 17c when the receiving housing C is in the folded position, and receives the receiving housing C. Is rotated 180 ° in the forward / reverse direction from the folding position, it fits into the other engaging recess 17c in any case. The end portion of the spherical body 21 that is positioned forward in the second direction always protrudes forward in the second direction from the holding hole 18a.

  An elastic leaf spring (biasing means) 22 is placed on the end face of the holding member 18 facing the front side in the second direction. The other end portion of the leaf spring 22 away from the raceway plate 17 in the radial direction of the hinge shaft 13 is fixed to the base portion 2a together with the holding member 18 by the bolt 20 penetrating the other end portion. The end of the leaf spring 22 on the hinge shaft 13 side is pressed against the end of the sphere 21 protruding from the holding hole 18a by the elasticity of the leaf spring 22 itself. As a result, the sphere 21 is urged toward the first direction and is constantly pressed against the track surface 17a. Therefore, when the receiver-side casing C rotates about the second rotation axis L2, and the hinge shaft 13 rotates accordingly, the sphere 22 rolls on the track surface 17a. Then, when the reception-side casing C is rotated to the initial position, the sphere 22 is fitted into the engagement recess 17b. As a result, the receiver-side casing C and the hinge body 2 are stopped at the initial position with a predetermined amount of force. When the receiver-side casing C is rotated 180 ° in the forward and reverse directions around the second rotation axis L2 from the initial position, the sphere 22 is fitted into the engaging recess 17c in any case. As a result, the receiving-side casing C and the hinge body 2 are stopped at a position 180 ° away from the initial position with a predetermined amount of force.

  A stopper mechanism (not shown) is provided between the hinge body 2 and the hinge shaft 13, and the receiving side casing C and the hinge body 2 are moved forward and backward from the folding position by the stopper mechanism. Rotation beyond 180 ° is prevented. Such a stopper mechanism may be provided between the transmission-side casing B and the reception-side casing C.

  When assembling the second click mechanism 16 in the hinge device 1 having the above-described configuration, first, the hinge shaft 13 is inserted into the through hole 2d of the hinge body 2 from the distal end portion (the other end portion) in the first direction. Then, the flange portion 13a is abutted against the base portion 2a. As a result, the hinge shaft 13 is prevented from moving in the first direction relative to the hinge body 2. A track plate 17 is fitted to one end of the hinge shaft 13 from the tip thereof in the first direction. The track plate 17 is fitted until it contacts the flange portion 13a. Thereby, the movement of the track plate 17 in the first direction is prevented. Next, the holding member 18 is placed on the surface of the base portion 2 a facing the second direction, and the end portion of the holding member 18 is opposed to the raceway surface 17 a of the raceway plate 17. Then, the sphere 22 is inserted into the holding hole 18a. Next, the plate spring 22 is placed on the holding member 18. Then, the assembly of the second click mechanism 16 is completed by screwing and tightening the bolt 20 penetrating the holding member 18 and the leaf spring 22 to the base portion 2a.

  Thus, the leaf spring 22 that is a member assembled at the end of the assembly of the click mechanism 16 is fixed to the hinge body 2 via the holding member 18 without being fixed to the hinge shaft 13. 18 can be easily and firmly fixed. Therefore, the click mechanism 16 can be easily assembled. When the leaf spring 22 is placed on the holding member 18, the movement of the hinge shaft 13 in the first direction is blocked by the flange portion 13 a, and the movement in the second direction is prevented by the leaf spring 22 from the spherical body 21 and the raceway plate. 17 is blocked. Therefore, when the bolt 20 is tightened to fix the holding member 18 and the leaf spring 22 to the base 2a of the hinge body 2, it is not necessary to hold the hinge shaft 13 so as not to come out of the through hole 2d. Therefore, the bolt 20 can be easily tightened, and as a result, the second click mechanism 16 can be more easily assembled.

  Next, another embodiment of the hinge device according to the present invention will be described.

A ball portion (engaging member) 22b is integrally provided at the tip (one end) of the leaf spring 22A. The ball portion 22b is pressed against the raceway surface 17a by the urging force of the leaf spring 22A. In addition, the ball portion 22b is disposed so as to be detachably engaged with either of the engagement recesses 17d and 17e when the hinge shaft 13A and the raceway plate 17A rotate to a predetermined position.

  FIG. 10 shows a third embodiment of the hinge device according to the first aspect of the present invention. In this hinge device, a second click mechanism 16B is used in place of the second click mechanism 16. The second click mechanism 16 </ b> B has a raceway plate 17 </ b> B that replaces the raceway plate 17. Engagement protrusions (engaged portions) 17f and 17g having a substantially hemispherical shape are formed on the raceway surface 17a of the raceway plate 17B. On the other hand, a curved portion (engaging member) 22c having a concave curved surface made of a part of a spherical surface is provided at the tip of the leaf spring 22B. The curved portion 22c is pressed against the raceway surface 17a by the urging force of the leaf spring 22B. Moreover, the bending portion 22c is disposed so as to be detachably engaged with either of the engagement protrusions 17f and 17g when the hinge shaft 13A and the raceway plate 17B are rotated to predetermined positions.

It is arranged in a state that accommodates. A hole 25c is formed in the center of the bottom surface of the main body 25a. A front end portion of the hinge shaft 13 in the second direction is fitted into the hole 25c so as to be rotatable. The end surface of the hinge shaft 13 facing the second direction is substantially in contact with the bottom surface of the hole 25c. Thereby, the movement to the 2nd direction of the hinge axis | shaft 13 is blocked | prevented. The flange portion 25b is integrally provided on the outer peripheral surface of the opening side end portion of the main body portion 25a. The fixing member 25 is fixed to the hinge main body 2 by tightening a bolt (not shown) that passes through the flange portion 25 b and is screwed to the hinge main body 2.

  The main body 25a may be configured by a plate material having a “U” shape without being formed in a cylindrical shape.
