[First Embodiment]

  A first embodiment of the present invention will be described with reference to FIGS. FIG. 1 is a perspective view showing a hinge device according to the first embodiment, FIG. 2 is an exploded perspective view thereof, and FIG. 3 is a front view showing the hinge device frame and its vicinity cut away. The hinge device shown in FIGS. 1 to 3 is an example of the present invention, and the present invention is not limited to such a configuration.

  The hinge device 2 is provided with an opening / closing shaft 8 as a first shaft supported by the pair of shaft support portions 4, 6, and a frame 10 is rotatably supported by the opening / closing shaft 8. A rotating shaft 12 is rotatably supported as a second shaft on the frame 10, and the rotating shaft 12 is arranged in a direction intersecting with the opening / closing shaft 8.

  An end 14 of the rotating shaft 12 that penetrates the frame 10 protrudes inside the frame 10, and a cam plate 16 is fixed to the rotating shaft 12 that protrudes inside the frame 10, and the cam plate 16 and the frame 10 are fixed. Between them, a spring plate 18 fixed to the frame 10 is installed.

  The cam plate 16 is formed with a stopper 20 and cutout recesses 22 and 24. The stopper 20 protrudes from the circumferential surface portion of the cam plate 16 in the radial direction, hits the stopper window portion 28 or the stopper window portion 30 of the standing wall portion 26 of the frame 10, and restricts the rotation angle of the rotating shaft 12. That is, if the position where the stopper 20 hits the stopper window 28 is, for example, the rotation start point, the position where the stopper 20 hits the stopper window 30 is the rotation end point. The rotation angle from the rotation start point to the rotation end point is a rotation allowable angle θn of the rotation shaft 12 (for example, 330 degrees).

  In addition, the notch recesses 22 and 24 are located in the diameter direction of the cam plate 16, and a pair of protrusions 32 are formed on the spring plate 18 correspondingly. Since the spring plate 18 is bent so as to be convex toward the cam plate 16 and a restoring force is applied between the frame 10 and the cam plate 16, the protrusion 32 is brought into contact with the cam plate 16 due to contact with the cam plate 16. Friction due to the restoring force of the spring plate 18 acts on the rotation of the rotating shaft 12 as a rotational load. When the protrusion 32 reaches the notch recesses 22 and 24 and gets stuck, the load is released, A blocking force against rotation acts. As a result, a stable state is generated at the angular position where the protrusion 32 and the notch recesses 22 and 24 are engaged. A single or a plurality of so-called stop positions are set on the rotary shaft 12 between the rotation start point and the rotation end point by the cam plate 16, the spring plate 18 and the frame 10.

  A coil spring 34, a slider 36, and a cam mechanism 38 are supported on the opening / closing shaft 8 that supports the frame 10 inside the frame 10. For example, the slider 36 is integrally formed of synthetic resin. The coil spring 34 and the slider 36 are fixed. The coil spring 34 is fixed to the frame 10 and can rotate with the frame 10 around the opening / closing shaft 8, and the slider 36 can slide on the opening / closing shaft 8. is there. The cam mechanism 38 includes first and second cams 40 and 42. In the first embodiment, the cam mechanism 38 is, for example, a synthetic resin molding, and the cam 40 and the slider 36 are integrally formed. The cam 42 is fixed to the opening / closing shaft 8. That is, the cam 40 rotates with the frame 10, while the cam 42 is maintained in a non-rotating state. Therefore, when the projections 44 and 46 are matched due to the positional relationship between the projections 44 and 46 formed on the cams 40 and 42 and the recesses 48 and 50, the coil spring 34 is compressed and the slider 36 is compressed. When the projection 44 and the recess 50 or the projection 46 and the recess 48 match, the compression of the coil spring 34 is loosened, and the slider 36 is moved in the restoring direction of the coil spring 34. By such engagement of the cams 40 and 42 by the cam mechanism 38, one or a plurality of so-called stop positions are set for the rotation of the opening and closing shaft 8.

  A notch recess 52 is formed in the slider 36, and the notch recess 52 accommodates the end portion 14 of the rotating shaft 12 that protrudes inside the frame 10. The cutout recess 52 may be configured to accommodate the cam plate 16 including the end portion 14.

  Here, regarding the length L, width W, and depth D of the notch recess 52, the length L is set to be larger than the slide width of the slider 36, and the width W is the end of the rotating shaft 12 protruding inside the frame 10. In addition to the thickness of the portion 14, the width D is set to be larger than the width W of the portion accommodated in the notch recess 52. What is necessary is just to set to the magnitude | size exceeding the protrusion length of the part accommodated in. With this configuration, contact between the slider 36 and the rotary shaft 12 side is avoided to prevent the slider 36 from sliding, and a protruding portion on the rotary shaft 12 side is provided in the notch recess 52 of the slider 36. Since it can be accommodated, the hinge device 2 can be made compact.

  The end 14 of the rotary shaft 12 that penetrates the frame 10 protrudes to the inside of the frame 10, and a cam plate 16 is fixed to the rotary shaft 12 that protrudes to the inside of the frame 10. A spring plate 18 fixed to the frame 10 is installed between the frame 10. With this configuration, the axial width of the opening / closing shaft 8 of the frame 10 can be reduced, and the hinge device 2 can be compact. Has contributed to

  The shaft support portions 4 and 6 that support the opening and closing shaft 8 are formed with fixing portions 54 and 56 that are bent at a right angle, and a support arm 58 that supports the opening and closing shaft 8 is formed. A single or a plurality of fixing holes 60 are respectively formed in 56, and a long fixing hole 62 that matches the shape of the end of the opening / closing shaft 8 is formed in the support arm 58. The shaft 8 is inserted and fixed. Further, a spacer 64 is installed between the frame 10 and the shaft support portions 4 and 6, and a long-diameter fixing hole 66 is similarly formed in the spacer 64. The reason why the end of the opening / closing shaft 8 has a long diameter is to prevent the opening / closing shaft 8 from rotating, and any shape can be used as long as it has such a function. Good. In that case, the fixing holes 62 and 66 also need to have a shape that matches the shape of the end of the opening / closing shaft 8 as described above.

  The frame 10 is formed with bearing portions 68 and 70 that pass through the opening / closing shaft 8 and are supported by the opening / closing shaft 8. A bearing hole 72 that is slightly larger in diameter than the opening / closing shaft 8 is formed in each bearing portion 68, 70. Thus, the frame 10 can be smoothly rotated. A support arm 73 extending from the upper portion of the standing wall portion 26 is fixed to each bearing portion 68, 70, and this serves as a beam connecting the frame 10, each bearing portion 68, 70 and the standing wall portion 26. Therefore, the mechanical strength of the frame 10 is enhanced.

  A fixing plate 74 is attached to the other end of the rotating shaft 12 in parallel with the frame 10 as an attachment portion for attaching the hinge device 2 to a device or the like. The fixing plate 74 has a plurality of fixing holes. 76 is formed, and a fixing protrusion 78 is formed at a right angle to the flat portion of the fixing plate 74.

  Next, the operation of the hinge device 2 will be described with reference to FIGS. FIG. 4 is a diagram illustrating the opening / closing operation of the hinge device, FIG. 5 is a diagram illustrating the operation of the slider and the coil spring accompanying the opening / closing operation of the hinge device, and FIG. 6 is a diagram illustrating the rotation operation of the hinge device.

  The hinge device 2 realizes rotation of the frame 10 around the opening / closing shaft 8 (first rotation) and rotation of the rotation shaft 12 (second rotation) as two-axis rotations orthogonal to each other.

  (1) First rotation

  In the first rotation, as shown in FIG. 4A, the frame 10 can be rotated in the direction indicated by the arrow a from the position where the rotary shaft 12 is located below, and the position of FIG. The position on the way of rotation is shown. Then, as shown in FIG. 4C, the frame 10 is rotated to a position on the same straight line as the protruding direction of the support arm 58 and stopped at that position. That is, in this embodiment, the frame 10 can be rotated by 90 degrees, and the arrow b indicates the reverse direction.

  Corresponding to such a first rotation, at the position shown in FIG. 4A, as shown in FIG. 5A, the protrusions 44 and 46 of the cams 40 and 42 and the recesses 48 and 50 mesh. Maintain a stable state. In this case, the coil spring 34 is in the most relaxed state.

  When the frame 10 is rotated in the direction indicated by the arrow N and reaches the position shown in FIG. 4B, the cams 40 and 42 shift from the meshing state to the contact state between the protrusions 44 and 46, and the slider 36. Moves in the compression direction of the coil spring 34 (X1), and the coil spring 34 is in a compressed state. FIG. 5B shows this state, and the restoring force of the coil spring 34 acting on the cams 40 and 42 through the slider 36 is the largest. The user who is performing the rotation operation will feel a sense of torque.

  When the rotation of the frame 10 further proceeds, the state shifts to the state shown in FIG. 4C. In this state, the cams 40 and 42 are released from the contact state between the protrusions 44 and 46 and are brought into meshing again. The slider 36 moves in the direction opposite to the compression direction of the coil spring 34 (X2), and the coil spring 34 is released from the highly compressed state. FIG. 5C shows this state, and the restoring force of the coil spring 34 acting on the cams 40 and 42 through the slider 36 is the smallest. The user performing the rotation operation is released from the feeling of torque and feels a sense of stability.

  With respect to such rotation, the projecting portion on the rotary shaft 12 side is accommodated in the notch recess 52 of the slider 36, so that sliding of the slider 36 is not hindered, and there is no interference between the slider 36 and the rotary shaft 12. With the hinge device 2 made compact, a stable rotational operation can be obtained.

  (2) Second rotation

  In the second rotation, as shown in FIG. 6A, in the state where the stopper 20 is in contact with the edge of the stopper window 28, the protrusion 32 of the spring plate 18 is fitted in the notch recesses 22 and 24. It becomes a stable fixed state (basic state). When this state is used as the rotation start point and the rotation is performed in the direction of the arrow θn, as shown in FIG. 6B, the protrusion 32 of the spring plate 18 is fitted into the notch recesses 22 and 24 during the rotation, and the rotation is stopped. If it is, it will be in the stable fixed state.

  If the rotation is advanced in the direction of the arrow θn from this state, the stopper 20 comes into contact with the edge of the stopper window portion 30 and the rotation is prevented, and the protrusion 32 of the spring plate 18 is fitted in the notch recesses 22 and 24 and is stabilized. It becomes a fixed state. That is, this state is the rotation end point. Even if the rotation end point is set as the rotation start point and the rotation is performed in the direction opposite to the direction of the arrow θn, a similar stable state can be obtained during the rotation, and a stable fixed state can be obtained at the rotation end point.

  With respect to such rotation, as described above, the projecting portion on the rotating shaft 12 side is accommodated in the notch recess 52 of the slider 36, and the slider 36 is similarly prevented from rotating without being prevented from rotating. With the device 2, a stable rotation operation on the rotary shaft 12 side can be obtained.

  The device 200 including the hinge device 2 includes a first member 202 and a second member 204, and the members 202 and 204 are connected by the hinge device 2. The member 202 is fixed to the shaft support portions 4 and 6 of the hinge device 2 with fixing screws 206. The member 204 is fixed to the fixing plate 74 of the hinge device 2 with a fixing screw 208.

  According to such a configuration, the two-axis rotation function of the hinge device 2 can open and close the member 204 with respect to the member 202 in the direction indicated by the arrow m as shown in FIG. 7, and as shown in FIG. In addition, the relative positional relationship between the first member 202 and the member 204 can be rotated and displaced as indicated by the arrow n about the rotation shaft 12. In this case, the open / close range (m) is 90 degrees and the rotation range (n) is about 330 degrees.

  If such biaxial rotation is possible, the device 200 can be applied to, for example, a video camera, a mobile phone, and the like, and can realize a desired rotational displacement, thereby improving convenience.
