The best mode for carrying out the present invention will be described below with reference to the drawings.
1 to 11 show a first embodiment of a rotary antenna according to the present invention. The rotary antenna 1 according to this embodiment includes a base member 2, a holder 3, and a hinge device 4, as shown particularly in FIGS.

  The base member 2 is formed with first and second support wall portions 21 and 22. The first and second support wall portions 21 and 22 are arranged to be separated from each other and opposed to the separation direction. The first and second support wall portions 21 and 22 are formed with first and second connection holes 21a and 22a penetrating them in the opposing direction, respectively. The first and second connection holes 21a and 22a are arranged with their axes aligned.

  The holder 3 has a main body 31 (a portion located between the first and second connecting holes 21a and 22a). The main body portion 31 is disposed between the first and second support wall portions 21 and 22. The main body portion 31 is formed with a third connection hole 31a penetrating therethrough. The third connection hole 31a is arranged with its axis line coincided with the axis lines of the first and second connection holes 21a and 22a. A boss portion 32 that protrudes in a direction orthogonal to the axis of the main body 31 is formed on the outer peripheral surface of the main body 31. The antenna element 5 is screwed and fixed to the boss portion 32.

  The hinge device 4 is inserted into the first, second and third connecting holes 21a, 22a, 31a. By this hinge device 4, the base member 2 and the holder 3 are coupled so as to be rotatable about the axis L of the first, second and third coupling holes 21a, 22a, 31a. In the following, for convenience of explanation, it is assumed that the holder 3 rotates with respect to the base member 3.

  The holder 3 can rotate in the range from the front deployment position shown in FIG. 1 to the rear deployment position shown in FIG. 3 through the intermediate position shown in FIGS. 2 and 4, at the front deployment position, the intermediate position, and the rear deployment position. The hinge device 4 is fixed in a non-rotatable position with a click feeling with a predetermined amount of force. Moreover, when the holder 3 is located within a range separated from the front deployment position, the intermediate position, and the rear deployment position by a predetermined angle (for example, 10 °), that is, in the vicinity of the front deployment position, the middle position, and the rear deployment position When it is in the position, it is rotated by the hinge device 4 to the front deployed position, the intermediate position, and the rear deployed position, respectively. When the holder 3 is located between the vicinity of the front deployment position and the vicinity of the intermediate position, or between the vicinity of the intermediate position and the vicinity of the rear deployment position, the holder 3 is stopped at an arbitrary position with a predetermined magnitude of force.

  In the direction from the intermediate position to the front deployment position, the holder 3 has a slight angle (for example, 1 to 2 °) beyond the front deployment position until the boss portion 32 hits the front regulation surface 23 formed on the base member 2. In the direction from the intermediate position to the rear deployment position, a slight angle (for example, 1 to 3) beyond the rear deployment position until the boss portion 32 abuts on the rear regulating surface 24 formed on the base member 2. 2 degrees), the holder 3 can be freely rotated even when the boss portion 32 abuts against any of the front regulating surface 23 and the rear regulating surface 24. 3 is rotated by the hinge device 4 to the front deployment position or the rear deployment position.

  As shown in FIGS. 5 and 8 to 11, the hinge device 4 includes a first hinge member 41 and a second hinge member 42, a fixed member 43, a movable member 44, a coil spring (biasing means) 45, and a connecting shaft 46. Is the main offensive factor.

  The first hinge member 41 has a cylindrical shape with a circular cross section, and at one end thereof (the right end portion in FIG. 5; the left and right are hereinafter referred to as the left and right in the drawing), the bottom 41a is formed. Is formed. A through hole 41b is formed at the center of the bottom 41a. The connecting shaft 46 is rotatably and slidably inserted into the through hole 41b. A head 46 a is formed at the right end of the connecting shaft 46. When the bottom 41 a comes into contact with the head 46 a, the first hinge member 41 can move further to the right with respect to the connecting shaft 46. I can't. A cover 49 is detachably mounted on the head 46a of the connecting shaft 46.

  The second hinge member 42 has a disc shape, and is arranged such that its axis coincides with the axis of the first hinge member 41. A through hole 42 a is formed at the center of the second hinge member 42. The left end portion of the connecting shaft 46 is rotatably and slidably inserted into the through hole 42a. However, the second hinge member 42 is prevented from moving to the right from the position shown in FIG. 5 with respect to the connecting shaft 46 by abutting against an annular step surface 46 b formed on the outer peripheral surface of the connecting shaft 46. . As will be described later, the second hinge member 42 does not rotate with respect to the connecting shaft 46. Therefore, the connecting shaft 46 may be fitted in the through hole 42a so as not to rotate.

  The fixing member 43 has a disk shape with the same diameter as the second hinge member 42, and is arranged such that its axis coincides with the axis of the first and second hinge members 41, 42. A through hole 43 a is formed at the center of the fixing member 43. The left end portion of the connecting shaft 46 penetrating the second hinge member 42 is inserted into the through hole 43a so as not to rotate. Moreover, the fixing member 43 is pressed against the annular step surface 46b via the second hinge member 42 by crimping the left end portion of the connecting shaft 46 protruding from the through hole 43a. As a result, the second hinge member 42 and the fixing member 43 are immovable with respect to the connecting shaft 46. If the 2nd hinge member 42 and the fixing member 43 cannot move to the left from the predetermined position shown in FIG. 5, you may move to the right. However, even if the second hinge member 42 and the fixed member 43 are movable to the right, the second hinge member 42 is moved by the coil spring 45 via the movable member 44 and the pair of spheres 47A and 47B, as will be described later. Since it is urged to the left, the second hinge member 42 and the fixing member 43 do not actually move to the right.

  The second hinge member 42 is non-rotatably connected to the fixing member 43. Therefore, the second hinge member 42 does not rotate or move with respect to the fixed member 43 and is almost integrally connected. Therefore, the second hinge member 42 and the fixing member 43 may be integrally formed. Further, since the fixing member 43 cannot rotate with respect to the connecting member 46, the second hinge member 42 also cannot rotate with respect to the connecting shaft 46. However, the second hinge member 42 and the fixing member 43 may be rotatable with respect to the connecting shaft 46. In such a case, the first hinge member 41 may not be rotatable with respect to the connecting shaft 46. Alternatively, the first hinge member 41, the second hinge member 43, and the fixing member 43 may be rotatable with respect to the connecting shaft 46.

  An engagement protrusion 43 b is formed on the left end surface of the fixing member 43. On the outer peripheral surface of the engagement protrusion 43b, a tapered portion 43c is formed at the tip, and an annular engagement recess 43d is formed in the middle portion. Further, the engaging protrusion 43b is elastically capable of expanding and contracting by forming a split groove 43e extending from the distal end surface to the proximal end portion.

  A movable member 44 is fitted to the left end portion (end portion on the opening side) of the first hinge member 41 so as not to rotate and to be movable in the axial direction of the first hinge member 41. A through hole 44a is formed in the central portion of the movable member 44, and a connecting shaft 46 is rotatably and slidably inserted into the through hole 44. Since the movable member 44 cannot rotate with respect to the first hinge member 41, the movable member 44 cannot rotate with respect to the connecting shaft 46 when the connecting shaft 46 cannot rotate with respect to the first hinge member 41. There may be.

  A coil spring 45 is provided between the movable member 44 and the bottom 41 a of the first hinge member 41. The coil spring 45 is arranged on the connecting shaft 46 in an extrapolated state. The coil spring 45 biases the movable member 44 toward the second hinge member 42.

  A pair of spheres (convex portions) 47A and 47B are embedded and fixed on the surface of the movable member 44 facing the second hinge member 42 in a state in which a part thereof protrudes to the second hinge member 42 side. The pair of spheres 47 </ b> A and 47 </ b> B are arranged 180 degrees apart in the circumferential direction on a circle centered on the axis of the first hinge member 41. Three or more spheres may be provided. Further, the protrusions may be formed integrally with the movable member 44 in place of the spheres 47A and 47B. The pair of spheres 47 </ b> A and 47 </ b> B are pressed against the surface of the second hinge member 42 facing the movable member 44 by the biasing force of the coil spring 45.

  A pair of engaging recesses (recesses) 48 </ b> A and 48 </ b> B are formed on the surface of the second hinge member 42 that faces the movable member 44. The pair of engaging recesses 48A and 48B are arranged 180 ° apart in the circumferential direction on a circle having the same center and the same diameter as the circle in which the pair of spheres 47A and 47B are arranged. In addition, when the first hinge member 41 is rotated to a predetermined first position with respect to the second hinge member 42, the spheres 47A and 47B are engaged with the engagement recesses 48A and 48B by the coil spring 45, respectively. As a result, the first and second hinge members 41 and 42 are fixed in a non-rotatable position at the first position with a click feeling with a predetermined amount of force. Therefore, the first click mechanism is configured by the spheres 47A and 47B, the engagement recesses 48A and 48B, and the coil spring 45. When the first hinge member 41 rotates 180 ° from the first position with respect to the second hinge member 42 and reaches the second position, the spheres 47A and 47B are engaged with the engagement recesses 48B and 48A by the coil spring 45, respectively. It is done. As a result, the first and second hinge members 41 and 42 are fixed in a non-rotatable position at the second position with a click feeling with a predetermined amount of force. Therefore, the second click mechanism is configured by the spheres 47A and 47B, the engagement recesses 48B and 48A, and the coil spring 45.

  On the surface of the second hinge member 42 facing the movable member 44, another pair of engaging recesses (recesses) 48C and 48D are formed. The engaging recesses 48C and 48D are arranged on the same circle as the engaging recesses 48A and 48B, but are arranged apart from the engaging recesses 48A and 48B in the circumferential direction by a predetermined angle. The angle between the engagement recess 48A and the engagement recess 48C and the angle between the engagement recess 48B and the engagement recess 48D are set to be the same. Accordingly, when the first hinge member 41 is rotated by a predetermined angle from the first position with respect to the second hinge member 42 to reach the third position, the spheres 47A and 47B are respectively brought into the engagement recesses 48C and 48D by the coil spring 45. Be engaged. As a result, the first and second hinge members 41 and 42 are fixed in a non-rotatable position at the third position with a click feeling with a predetermined force. The spherical bodies 47A and 47B, the engaging recesses 48C and 48D, and the coil spring 45 constitute a third click mechanism. The angle between the first position and the third position is set to be the same as the angle between the previous deployed position and the intermediate position.

  When the first hinge member 41 is located within a predetermined range away from the first position by a predetermined angle (for example, 10 °) in the circumferential direction, the inclined outer peripheral surfaces of the spheres 47A and 47B are engaged with the engaging recesses 48A and 48B. The peripheral edge of the In this state, the urging force of the coil spring 45 is converted into a rotating urging force that rotates the first hinge member 41 toward the first position. Therefore, when the first hinge member 41 is allowed to freely rotate within the predetermined range, the first hinge member 41 is rotated to the first position and is kept unrotatable there. This is the same when the first hinge member 41 is located within a range away from the second position by a predetermined angle and within a range away from the third position by a predetermined angle. When the first hinge member 41 located in the position is allowed to rotate freely, the first hinge member 41 is rotated to the second position or the third position by the rotational biasing force caused by the biasing force of the coil spring 45. And is kept non-rotatable at each position.

  The hinge device 4 having the above configuration is inserted in the order of the first connecting hole 21a, the third connecting hole 31a, and the second connecting hole 22a with the fixing member 43 first. And the annular protrusion 22b formed in the internal peripheral surface of the 2nd connection hole 22a fits in the engagement recessed part 43d, and the hinge apparatus 4 cannot escape to the 1st-3rd connection holes 21a, 22a, 31a. It is installed.

  As shown in FIG. 5, the first hinge member 41 is directly fitted in the first connection hole 21a and the third connection hole 31a. In this case, the first hinge member 41 is non-rotatably fitted in the third connecting hole 31a, but is rotatably fitted in the first connecting hole 21a. Therefore, the first support wall 21 of the base member 2 and the holder 3 are rotatably connected via the first hinge member 41. The second hinge member 42 is fitted in the second connection hole 22a and the third connection hole 31a. The second hinge member 42 is non-rotatably fitted in the second connection hole 22a, but is rotatably fitted in the third connection hole 31a. Therefore, the second support wall portion 22 of the base member 2 and the holder 3 are rotatably connected via the second hinge member 42.

  The first support wall 21 and the holder 3 are rotatably connected via a first hinge member 41, and the second support wall 22 and the holder 3 are rotatably connected via a second hinge member. Thus, the base member 2 and the holder 3 are rotatably connected. In addition, the first hinge member 41 is non-rotatably fitted in the third connection hole 31a of the holder 3, and the second hinge member 42 is non-rotatably fitted in the second connection hole 22a of the base member 2. Therefore, when the holder 3 rotates, the first hinge member 41 and the movable member 44 rotate with respect to the second hinge member 42. In this case, when the first hinge member 41 is positioned at the first position, the base member 2, the holder 3, and the hinge device 4 are aligned so that the holder 3 is positioned at the front deployment position.
