According to this, the base end side shaft rod is supported by the base portion so as to be rotatable around the axis of the base end portion side shaft rod, and the free end side shaft rod supports the monitor device. Since the monitor device is rotated in the direction around the axis of the free end side shaft rod and the vertical direction of the monitor device is maintained in a predetermined state, the rotation unit is supported. The height position of the monitor device can be adjusted in a wide range by rotating the base end side shaft rod around the axis.

  In the present invention, the base end side shaft rod is passed through the base portion, and the rotating portion can be rotated while straddling the upper portion of the base member with the left and right arms. Further, according to the present invention, the base end side shaft rod has a large-diameter portion at an intermediate position in the axial direction, and the base portion is rotated by the frictional force caused by the pinching by sandwiching the large-diameter portion in the base portion.

Embodiment 1
Embodiment 1 of the present invention will be described. First, an outline of the support 10 according to this embodiment will be described with reference to FIG. The support 10 includes a base portion 12, a rotation portion 14, and a monitor attachment portion 16. The base portion 12 is attached to a place where the monitor device is to be installed in the interior of the automobile using the built-in suction cup 30 (FIG. 1). The rotating part 14 is connected to and supported by the base part 12 so as to be rotatable in an angle range of 90 ° or more about the rotating shaft 18. The rotation shaft 18 is arranged in parallel to the plane to which the opening end surface of the recess 28 (FIG. 1) of the base portion 12 belongs. The monitor mounting portion 16 is connected to and supported by the distal end portion of the rotating portion 14 so as to be rotatable in an angle range of 90 ° or more around the rotating shaft 20, and the second rotating portion 22. An installation portion 24 connected to and supported by a pivot 23 (FIG. 1) formed on the upper surface of the central portion of the center portion is provided. The rotating shaft 20 is disposed in parallel to the rotating shaft 18. A monitor device 25 (FIGS. 1 and 3) such as a liquid crystal display constituting a display device of the car navigation system is detachably attached to the front surface 24a of the installation unit 24 using screws. According to the above configuration, the height position of the monitor device 25 is adjusted by rotating the rotating unit 14 about the rotating shaft 18 with the base 12 mounted on the dashboard with the suction cup 30. The At this time, the rotation unit 14 is held at an adjusted rotation angle with respect to the base unit 12. Further, the angle of the monitor device 25 in the vertical direction is adjusted by rotating the second rotating portion 22 about the rotating shaft 20. At this time, the second rotation unit 22 is held at the adjusted rotation angle with respect to the rotation unit 14. Further, the inclination of the monitor device 25 is adjusted by tilting the installation portion 24 about the pivot 23. At this time, the installation part 24 is held at the adjusted tilt angle with respect to the second rotation part 22.

  Next, the detailed configuration of each part of the support 10 will be described mainly with reference to FIG. The base portion 12 includes a cover 26 made of hard synthetic resin, metal or the like. The cover 26 has a recess 28 that opens downward. A suction cup 30 is accommodated in the recess 28. The suction surface 32 of the suction cup 30 is directed downward. A polymer gel sheet 33 is detachably attached to the entire suction surface 32 of the suction cup 30 as an adhesive polymer gel layer using the adhesive property of the polymer gel sheet 33 itself. The suction cup 30 to which the polymer gel sheet 33 is attached is adsorbed on a suction surface 35 such as a dashboard by a suction action. At this time, the polymer gel sheet 33 adheres to the surface to be adsorbed 35 and functions to maintain the adsorbing state for a long period of time by maintaining the adsorbing force by the suction cup 30.

  A plurality of air vent holes 33a are formed at a plurality of positions different in the circumferential direction and a plurality of positions different in the radial direction at positions closer to the inner peripheral side in the surface of the polymer gel sheet 33. Due to the presence of the air vent hole 33a, when the polymer gel sheet 33 is attached to the suction surface 32 of the suction cup 30, the air between the suction surface 32 and the polymer gel sheet 33 can be vented through the air vent hole 33a. A sufficient adsorbing force retention effect by the polymer gel sheet 33 can be obtained. Also, when the polymer gel sheet 33 is deteriorated due to long-term use or the like and the polymer gel sheet 33 is replaced with a new one, the air between the adsorption surface 32 and the new polymer gel sheet 33 is easily extracted through the air vent hole 33a. Therefore, a sufficient adsorbing force retention effect by the polymer gel sheet 33 can be obtained even after replacement. Further, at the position closer to the outer peripheral side in the surface of the polymer gel sheet 33, four misalignment prevention holes 33b are formed at equal intervals in the circumferential direction. The misalignment prevention convex portion 30a formed on the suction surface 32 of the suction cup 30 is fitted into the misalignment prevention hole 33b. This prevents the polymer gel sheet 33 from being displaced from the adsorption surface 32 when the support 10 is attached to the adsorption surface 35 or during normal use after attachment.

  FIG. 4 shows an arrangement pattern example of the air vent holes 33a and the misalignment prevention holes 33b in the polymer gel sheet 33. As shown in FIG. The polymer gel sheet 33 has the same outer shape as the suction cup 30. The suction cup 30 of this embodiment is circular, and the polymer gel sheet 33 is configured in a circular shape with the same outer diameter as the suction cup 30. The air vent holes 33a are concentrically arranged at two radial positions. Among these, four air vent holes 33a on the inner peripheral side are arranged at equal intervals in the circumferential direction. Further, eight air vent holes 33a on the outer peripheral side are arranged at equal intervals in the circumferential direction. A part of the four air vent holes 33a on the inner peripheral side and the eight air vent holes 33a on the outer peripheral side are arranged radially at the same circumferential position. Four misalignment prevention holes 33b are arranged at equal intervals in the circumferential direction at one radial position on the outer peripheral side of the air vent hole 33a.

  In FIG. 1, the entire upper surface 30 b of the peripheral portion of the suction cup 30 is abutted and supported by the lower surface 26 a of the peripheral portion of the cover 26. On the outermost peripheral portion of the cover 26, an edge portion 26b surrounding and hiding the outer peripheral edge portion of the suction cup 30 is formed so as to protrude downward over the entire periphery. On the outer peripheral portion of the cover 26, two raised portions 26c for placing a finger when the base portion 12 is detached from the attracted surface 35 are formed. A disc 40 made of hard synthetic resin, metal or the like is embedded in the central portion of the suction cup 30. A pulling bar 42 having a flat cross-sectional shape is formed on the upper surface of the central portion of the disk 40 so as to be integral with the disk 40 and project upward. The pull bar 42 passes through a hole 44 formed in the center of the upper surface of the cover 26 and protrudes above the cover 26. The pull bar 42 is movable in the vertical direction with respect to the cover 26. A lid portion 46 is rotatably connected to the upper portion of the pull rod 42 by a shaft rod 48, so that the lid portion 46 is rotatable about a rotation shaft 50 passing through the center of the shaft rod 48. The rotation shaft 50 is arranged in parallel with the rotation shafts 18 and 20. The lid portion 46 has a function of hiding the heads of the holding plate 54 and the screw 56 exposed on the cover 26, and a cam portion 57 (FIGS. 5, 6, and 7) configured at the base end portion of the lid portion 46. It has a function of pulling up the pull bar 42 with respect to the cover 26 by contact with the upper surface of the cover 26. A concave portion 52 is formed on the upper surface of the cover 26 to accommodate and support the lower half of the base end side shaft rod 62 of the rotating portion 14. On the upper surface of the cover 26, a holding plate 54 that accommodates the upper half of the base end side shaft rod 62 is fixed by four screws 56. The four screws 56 pass through the cover 26 and are screwed into a nut (not shown) in the recess 28 of the cover 26 to be fixed. As a result, the base end side shaft rod 62 is supported by the base portion 12 so as to be rotatable about the rotation shaft 18 passing through the central axis thereof. The holding plate 54 and the four screws 56 are hidden from view by turning the lid portion 46 to the closed position and become invisible.

  A metal plate 59 is embedded in the center of the upper surface of the cover 26. A hole 59a that communicates with a hole 44 formed in the cover 26 is formed at the center of the metal plate 59, and a pull bar 42 is passed through the hole 59a. The cam portion 57 (FIGS. 5, 6, and 7) formed at the base end portion of the lid portion 46 is brought into contact with the surface of the metal plate 59 by rotating the lid portion 46 in the closed position direction. The rod 42 is pulled up with the central part of the suction cup 30.

A side shaft rod 62 and a free end side shaft rod 64 that interconnects the free ends of the arms 58 and 60 are provided, and the whole is configured in a rectangular frame shape. In this embodiment, the arms 58 and 60 and the base end side shaft rod 62 are integrally formed of hard synthetic resin. A large-diameter portion 66 swelled in a spherical shape is formed at the axially central portion of the base end side shaft rod 62. The large diameter portion 66 functions to increase the frictional force generated between the base end portion side shaft rod 62 and the cover 26 and the pressing plate 54 by making a part of the base end portion side shaft rod 62 have a large diameter. Is. This frictional force prevents the rotating unit 14 from rotating downward due to the load of the monitor device 25. The frictional force generated between the base end side shaft rod 62 and the cover 26 and the pressing plate 54 can be adjusted by the amount of screwing into which the four screws 56 for mounting the pressing plate 54 to the cover 26 are screwed into the nut. . Therefore, by setting the frictional force to an appropriate magnitude in advance by the screwing amount, the driver or the like applies a force to the monitor device 25 by hand to turn the rotating portion 14 relative to the base portion 12 (that is, The height position of the monitor device 25 can be adjusted, and the adjusted rotation position is maintained.

  In this embodiment, the free end side shaft rod 64 of the rotating portion 14 is composed of a metal screw rod having a screw portion formed at least at the tip. The screw rod 64 passes from a hole 70 formed on the side surface of the free end of the arm 60 to a hole 68 formed on the side surface of the free end of the arm 58 through a hole 72 formed in the second rotating portion 22. . The tip of the screw rod 64 protrudes from the hole 68 of the arm 58, and the screw rod 64 is attached between the arms 58 and 60 by screwing the protruding screw portion into the nut 74. At this time, the second rotating portion 22 is sandwiched between the arms 58 and 60. In this state, by adjusting the screwing amount of the screw rod 64 with respect to the nut 74, the force with which the arms 58 and 60 pinch the second rotating portion 22 is changed, whereby the arms 58 and 60 and the second rotating portion 22 The frictional force of the abutting surface changes. Therefore, by setting the frictional force in advance to an appropriate magnitude according to the screwed amount of the screw rod 64 with respect to the nut 74, the driver or the like applies force to the monitor device 25 by hand to perform the second rotation on the rotating unit 14. The rotation position of the moving part 22 can be adjusted, and this adjusted rotation position is maintained.

  The second rotating part 22 of the monitor mounting part 16 is made of hard synthetic resin, metal or the like. As clearly shown in FIG. 1, a spherical pivot 23 is formed integrally with the second rotating portion 22 on the upper surface of the central portion of the second rotating portion 22. The upper half of the pivot 23 is accommodated in a spherical concave pivot receiver 76 formed on the lower surface of the installation portion 24. A metal pivot holding ring 80 is loosely fitted to the base 78 of the pivot 23. The pivot holding ring 80 is accommodated in a recess 24c formed on the lower surface of the installation portion 24, and is attached to the lower surface of the installation portion 24 by two screws 82 (FIG. 3) inserted into the installation portion 24 from below. . The two screws 82 are screwed onto the nuts 84 (FIG. 3) on the upper surface of the installation portion 24 and fastened. In this way, the installation part 24 is connected to the second rotation part 22 by the pivot 23 so as to be tiltable in each direction. In this state, the pressing force of the pivot holding ring 80 against the pivot 23 is changed by adjusting the screwing amount of the screw 82 with respect to the nut 84, whereby the frictional force between the pivot 23 and the pivot receiver 76 and the pivot holding ring 80 is changed. Change. Therefore, by setting the frictional force to an appropriate magnitude in advance according to the screwing amount of the screw 82 with respect to the nut 84, the driver or the like applies force to the monitor device 25 by hand to install the second rotating part 22. The tilt position of 24 can be adjusted, and the adjusted tilt position is maintained. The monitor device 25 is detachably attached to the front surface 24a of the installation unit 24 by screws (not shown) that are passed through holes 24b formed in the installation unit 24.

  A procedure for mounting the support 10 having the above configuration on the suction surface 35 such as a dashboard will be described. Prior to mounting on the suction surface 35, the lid 46 is set to the open position as shown in FIG. In this state, the support 10 is placed at a desired position on the attracted surface 35. Next, the inner surface portion 46a exposed to the upper side of the lid portion 46 is strongly pressed downward with a finger to push down the pull bar 42. By doing so, the central portion of the suction cup 30 is pushed down, the air in the space 86 (FIG. 1) between the polymer gel sheet 33 and the surface to be adsorbed 35 is discharged, and the polymer gel sheet 33 has a wide area on the surface to be adsorbed 35. Adhere with. The state at this time is shown in FIG. From this state, the lid portion 46 is further rotated to the closed position as shown in FIG. 1, so that the cam portion 57 (FIGS. 5, 6, and 7) abuts on the surface of the metal plate 59 and the pull bar 42 is moved. The space 86 between the polymer gel sheet 33 and the surface to be attracted 35 is pulled down with the central portion of the suction cup 30 and the suction force is generated. As a result, the support 10 is strongly attached to the attracted surface 35. In this state, as shown in FIG. 7, the driver or the like can manually adjust the height position of the monitor device 25 by rotating the rotation unit 14 about the rotation shaft 18. In this case, since the rotating portion 14 is disposed so as to straddle the lid portion 46 that protrudes upward, when the rotating portion 14 is rotated, the lid portion 46 is formed in the cavity 87 configured in the frame of the rotating portion 14. Enters. Therefore, the rotation part 14 can rotate in a wide angle range without hitting the lid part 46. In the design of this embodiment, the rotation range of the rotation unit 14 around the rotation shaft 18 is 90 ° or more upward and 25 ° downward from a position parallel to the attracted surface 35, and 115 as a whole. It is set to more than °. Further, the rotation range of the monitor mounting portion 16 around the rotation shaft 20 is set wider than the rotation range of the rotation portion 14 around the rotation shaft 18. Therefore, the monitor device 25 is perpendicular to the attracted surface 35 by the cooperation of the rotation of the rotation unit 14 about the rotation axis 18 and the rotation of the monitor mounting unit 16 about the rotation axis 20. Since the rotation unit 14 can be rotated by 115 ° or more while maintaining the posture, the height position of the monitor device 25 can be adjusted in a wide range. Further, the tilt of the monitor device 25 can be adjusted by tilting the installation portion 24 around the pivot 23 (FIG. 1) of the second rotating portion 22. That is, by the tilting operation of the installation part 24, the monitor device 25 can tilt at least around the axis 21 (FIG. 1, FIG. 3) extending in the front-rear direction of the support tool 10. Even if it is inclined, the monitor device 25 can be kept horizontal. When the support 10 is removed from the attracted surface 35, the cover 26 is lifted by placing a finger on the raised portion 26c formed at the outer peripheral position of the cover 26, and the opening 26d on the side of the raised portion 26c (FIG. 7). Then, the finger is pointed in and the polymer gel sheet 33 together with the suction cup 30 is peeled off from the attracted surface 35.

The support 89 according to this embodiment is configured such that the rotation portion 14 can be tilted with respect to the base portion 12 instead of allowing the monitor mounting portion 16 to tilt with respect to the rotation portion 14. That is, as shown in FIG. 10, a recess 88 is formed between the opposing surfaces of the cover 26 and the pressing plate 54 through which the base end side shaft rod 62 is passed. The recess 88 has a spherical space 88a in the center in the axial direction, and communicates with the spherical space 88a and has cavities 88b and 88c on the left and right thereof. The cavities 88b and 88c gradually expand in the vertical direction as the distance from the spherical space 88a increases. The spherical space 88a accommodates a spherical large-diameter portion 66 formed at the axially central portion of the proximal end side shaft rod 62. As a result, the base end side shaft rod 62 is pivotable about the pivot shaft 18 passing through the center of the base end portion side shaft rod 62 and swings up and down around the center point 66a of the large diameter portion 66. It is supported by the base part 12 freely.

In the design of this embodiment, the tilt angle range of the rotating unit 14 is set to 30 ° (± 15 ° with respect to the reference surface, ie, the attracted surface 35), as shown in FIG. For this reason, even if the attracted surface 35 such as a dashboard is inclined, the monitor device 25 can be kept horizontal as long as it is within the tilt angle range. A monitor mounting portion 16 is attached to the free end side shaft rod 64. The monitor attachment portion 16 is configured by sandwiching the free end side axial shaft 64 between the installation portion 24 and the attachment jig 90 and connecting the installation portion 24 and the attachment jig 90 with four screws 92. As a result, the monitor mounting portion 16 is attached to the free end side shaft rod 64 so as to be rotatable about the rotation shaft 20 passing through the center of the free end side shaft rod 64. A monitor device 25 is placed on the installation portion 24 of the monitor attachment portion 16. The monitor device 25 is attached to the installation unit 24 by a screw (not shown) that passes from below through a hole 24 b formed in the installation unit 24.

  In the design of this embodiment, the rotation range of the rotation unit 14 around the rotation shaft 18 is 90 ° or more upward and 40 ° downward from a position parallel to the attracted surface 35, and 130 as a whole. It is set to more than °. Further, the rotation range of the monitor mounting portion 16 around the rotation shaft 20 is set wider than the rotation range of the rotation portion 14 around the rotation shaft 18. Therefore, the monitor device 25 is perpendicular to the attracted surface 35 by the cooperation of the rotation of the rotation unit 14 about the rotation axis 18 and the rotation of the monitor mounting unit 16 about the rotation axis 20. Since the rotating unit 14 can be rotated by 130 ° or more while maintaining the posture, the height position of the monitor device 25 can be adjusted in a wide range.

  In each of the above embodiments, the base portion 12 is attached to the attracted surface 35 by the suction cup 30, but the base portion 12 may be attached to the attracted surface 35 by a double-sided adhesive tape or the like instead of the suction cup 30.
