  An embodiment of a hinge device and a structure using the hinge device of the present invention will be described with reference to FIG. FIG. 1 is a perspective view showing a hinge device and a structure using the hinge device.

  The structural body 2 according to this embodiment constitutes, for example, a video camera, a mobile phone, or the like. The structure 2 includes first and second members 4 and 6, these members 4 and 6 are connected by a hinge device 8, the member 4 rotates based on the member 6, and between the members 4 and 6. It can be opened and closed. An arrow A indicates rotation of the member 4, and an arrow B indicates opening and closing between the members 4 and 6. The member 4 is, for example, a monitor unit, and the member 6 is, for example, a camera body in a video camera and a telephone body in a mobile phone.

  The hinge device 8 includes a plate-shaped mounting plate 10 and a pair of L-shaped mounting portions 12 and 14. The member 4 is fixed to the mounting plate 10 with screws 16, and the mounting portions 12 and 14. The member 6 is fixed by a screw 18, and the member 4 rotates around the first shaft portion 20 and opens and closes around the second shaft portion 22. A plate-like stopper 24 is attached to the shaft portion 20 with a spring plate 23 interposed therebetween, and the shaft portion 20 is rotated by a collision between a protrusion 26 of the stopper 24 and a stopper portion 28 bent from the attachment plate 10. And its scope is regulated.

  The hinge device 8 will be described with reference to FIGS. 2 is a plan view showing the hinge device 8, and FIG. 3 is a cross-sectional view taken along line III-III in FIG.

  A shaft portion 22 is rotatably supported by the attachment portions 12 and 14, and a rotation frame 30 having a C-shaped cross section that passes through the shaft portion 22 is rotatably supported. Annular spring plates 32 and 34 and washers 36 and 38 are respectively attached to the end portions of the shaft portion 22 projecting to the outer surface side of the attachment portions 12 and 14. Each of 34 and a washer 38 is sandwiched between a caulking portion 37 as a stopper formed at an end portion of the shaft portion 22 and outer surface portions of the attachment portions 12 and 14. As a result, the spring plates 32 and 34 are compressed, and the restoring force of each spring plate 32 and 34 acts between the washer 36 and the mounting portion 12 and between the washer 38 and the mounting portion 14. Within the space between the portions 12 and 14, the rotating frame 30 receives and holds the force in the compression direction by the restoring force of the spring plates 32 and 34. Further, the shaft portion 20 is held in a stopped state at an arbitrary opening / closing angle together with the rotation frame 30 and the shaft portion 22.

  The shaft portion 20 having the shaft portion 22 penetrated in the orthogonal direction has its tip portion penetrated into the through hole 31 of the rotating frame 30 and its intermediate portion is rotated to the bearing hole 42 of the cylindrical bearing body 40. It is supported movably. The mounting plate 10 is fixed to the end of the bearing body 40, and the bearing body 40 and the mounting plate 10 have a combined structure. A spring plate 23 and a stopper 24 are attached to the end of the shaft portion 20 penetrating the mounting plate 10 on the back side, and a crimping portion 48 as a stopper is formed. That is, the spring plate 23 and the stopper 24 are sandwiched between the mounting plate 10 and the caulking portion 48. For this reason, the spring plate 23 is held between the caulking portion 48 and the mounting plate 10 in a compressed state. As a result, the contact between the spring plate 23 and the mounting plate 10 generates an appropriate frictional force therebetween. Thus, the frictional force gives a load to the rotation on the mounting plate 10 side, and the mounting plate 10, that is, the member 4 side can be stopped and held at an arbitrary rotation angle.

  The hinge mechanism part of the hinge device 8 will be described with reference to FIG. FIG. 4 is an exploded perspective view showing a hinge mechanism portion of the hinge device 8.

A prismatic end portion 56 is provided on the end portion side. A first bearing portion 58 is formed across the flange portion 52 and the intermediate shaft portion 50, and the bearing portion 58 is formed in a direction intersecting with the shaft center of the shaft portion 20. In this embodiment, the shaft center and the bearing portion 58 are formed in an orthogonal direction, but the function of the hinge device 8 does not have to be in an orthogonal relationship.

  The shaft portion 22 that is pivotably passed through the bearing portion 58 of the shaft portion 20 is a cylindrical shaft, and is a pair of sliding grooves that are formed by recesses formed at a constant interval on the wall surface of the center portion. 60 and 62 are formed, and notches 64 and 66 are formed on both ends to form a rectangular end surface portion 68.

  Further, the bearing body 40 has a bearing hole 42 as a means for rotatably supporting the shaft portion 20, and a track portion 70 having a constant width and a large diameter is formed on the opening end side of the bearing hole 42. In this embodiment, the outer diameter of the track portion 70 is the same as the outer diameter of the flange portion 52 on the shaft portion 20 side. The track width of the track portion 70 corresponds to the sliding grooves 60 and 62 of the shaft portion 22, and the track portion 70 meshes with the sliding grooves 60 and 62, and the shaft portion 20 rotates and rotates on the track portion 70. The shaft portion 22 is rotatable. The track portion 70 is formed with a pair of second bearing portions 72 formed of curved concave portions, and is formed so as to be orthogonal to the bearing holes 42 in this embodiment. The bearing portion 72 corresponds to the bearing portion 58 of the shaft portion 20. The raceway portion 70 is formed with a pair of first concave portions 74 that are shallower than the bearing portion 72. With respect to the recess 74, the sliding grooves 60 and 62 constitute a second recess.

  The hinge device 8 meshes with each other by the slide grooves 60 and 62 of the raceway portion 70 and the shaft portion 22, and the shaft portion 22 can rotate around the section of the raceway portion 70 excluding the bearing portion 72. The rotation of the shaft portion 22 is restricted by the engagement of the slide portions 60 and 62 of the shaft portion 22 with the raceway portion 70 other than the portion of the bearing portion 72, and the rotation of the portion 22 is prevented independently. A rotation restricting portion 75 is configured. That is, the portion other than the bearing portion 72 of the track portion 70 is a portion that prohibits the rotation of the shaft portion 22 (rotation restricting portion 75), and the other portion is a portion that permits the rotation of the shaft portion 22 (bearing portion 72). ) Is set. The bearing portion 72 constitutes a rotation restriction release portion.

  In addition, a pair of locking projections 76 are formed on the end surface portion of the bearing body 40 opposite to the raceway portion 70, and the mounting plate 10 has a shaft portion 20 corresponding to the locking projections 76. A locking recess 80 is formed together with the through hole 78. The bearing body 40 is positioned on the mounting plate 10 by the locking projection 76 being inserted into the locking recess 80 and locked, and the through hole 78 matches the bearing hole 42.

  A stopper 24 is attached to the prismatic end portion 56 of the shaft portion 20 penetrating the bearing body 40 and the mounting plate 10 together with the spring plate 23 as an elastic member, and a crimping portion at the end of the prismatic end portion 56 is attached. 48 (FIG. 3), the prismatic end portion 56, the spring plate 23 and the stopper 24 are integrated, and the spring plate 23 and the stopper 24 can be rotated integrally with the bearing body 40. Through holes 82 and 84 are formed in the spring plate 23 and the stopper 24, respectively.

  The spring plate 23 is bent in the diametrical direction with the central through hole 82 as the center, and is installed in a stretched state between the mounting plate 10 and the stopper 24. Accordingly, a restoring force by the spring plate 23 acts between the stopper 24 and the mounting plate 10, and the shaft portion 20 is attracted to the mounting plate 10 side by the action of the restoring force. This attractive force depends on the restoring force. In this embodiment, the spring plate 23 is used, but a coil spring may be attached to the shaft portion 20 and act between the mounting plate 10 and the stopper 24.

  In this embodiment, a pair of engaging protrusions 86 are formed on the spring plate 23, and these engaging protrusions 86 are inserted into engaging recesses 88 formed on the stopper 24, so that the spring plate 23 and the stopper 24 is configured to be rotatable with the shaft portion 20 integrally.

  According to such a structure, the following rotation forms are realized.

  The hinge device 8 can be used for rotation on the member 4 side with the member 6 side fixed, rotation on the member 6 side with the member 4 side fixed, and opening / closing between the members 4 and 6.

  For convenience of explanation, if the bearing body 40 fixed on the member 4 side is set to rotate about the shaft portion 20, the sliding grooves 60, 62 of the shaft portion 22 as shown in FIGS. The bearing body 40 meshing with the track portion 70 can be rotated and moved into the recess 74 from the distance between the bearing 72 and the recess 74 (FIG. 5) (FIG. 6). 7) can be passed and rotated as indicated by arrow A in the angular range from the start point (end point) to the end point (start point) of the protrusion 26 of the stopper 24.

  In the rotation range of the bearing body 40, a constant torque is required outside the recess 74 due to the frictional force generated by the restoring force of the spring plate 23, whereas when the shaft portion 22 reaches the recess 74, As a result of the sliding grooves 60 and 62 of the shaft portion 22 being fitted into the recess 74 and the frictional force due to the restoring force being reduced, part of the torque is released and a stable fixed state is obtained. The user who performs the rotation operation can obtain a click feeling due to the difference in torque, and as a result, the rotation angle position with respect to the members 4 and 6 can be recognized. In this embodiment, a click feeling of every 90 degrees of the member 4 is obtained.

  In addition, since the sliding grooves 60 and 62 and the raceway portion 70 are in an engagement relationship, the rotation of the shaft portion 22 is prevented at portions other than the bearing portion 72, and the members 4 and 6 are removed at portions other than the bearing portion 72. It cannot be opened or closed.

  When the shaft portion 22 is engaged with the bearing portion 72 in the rotation range of the bearing body 40, the engagement between the sliding grooves 60 and 62 of the shaft portion 22 and the raceway portion 70 of the bearing body 40 is released. As a result, the rotation of the shaft portion 22 is permitted. That is, as shown in FIG. 8, the bearing portion 58 and the bearing portion 72 have a circular shape surrounding the shaft portion 22, and the shaft portion 22 can be rotated in the direction indicated by the arrow B. As a result, as shown in FIG. 9, the member 4 can be rotated from the right angle state (open state) to the parallel state (closed state) with respect to the member 6. Moreover, it can also be rotated from a closed state to an open state. In the closed state, the shaft portion 22 serves as a stopper, and the rotation of the bearing body 40 is prevented.

  Moreover, if the member 4 is rotated from the closed state to the open state and shifted to the state shown by the solid line in FIG. 9, the member 4 can be rotated as shown in FIGS. .

  Further, in the above embodiment, as shown in FIG. 10, if the bearing portion 72 is formed larger in diameter than the bearing portion 58, the space portions 90 and 92 are formed on the bearing portion 72 side. The coupling with the portion 22 is loose, that is, play is obtained in the rotation of the bearing body 40 relative to the shaft portion 22. As a result, even if the center of the bearing 72 is swung (ΔN) with respect to the center of the shaft 22, the shaft 22 can be rotated. That is, in FIG. 1, even if a twist is generated between the member 4 and the member 6, the member 4 can be rotated on the member 6 and allowed to stand still.

  In the embodiment, the shaft body 20 is rotated with the shaft portion 20 fixed, but the shaft portion 20 may be rotated with the bearing body 40 fixed.

  The track portion 70 may be formed in a protruding wall portion or a groove portion, and on the other hand, the shaft portion 22 side may be a groove portion corresponding to the protruding wall portion or a protruding wall portion corresponding to the groove portion.
