Japanese Patent Laying-Open No. 2008-232259 (FIG. 9)

  According to the conventional in-vehicle monitor support device, when the monitor device is detached from the mounting position of the dashboard or the like together with the in-vehicle monitor support device and is removed from the mounting position of the dashboard or the like due to a collision or the like during driving of the vehicle, it is exposed. There is a risk that the locked lever hits the passenger and injures the passenger. Further, the structure in which the lock lever is exposed has poor design.

  The present invention has been made in view of the above-described points, and provides an in-vehicle monitor support device that secures safety and improves design while preventing a lock lever for operating attachment / detachment of a suction cup from being exposed. It is something to be offered.

  The in-vehicle monitor support device according to the present invention includes a suction cup, a rod having one end connected to the central portion of the suction cup and the other end protruding outward from the outer surface of the suction cup, and a hole formed in the central portion. A case where the protruding portion of the rod passes through the hole so as to be movable in the axial direction of the rod and covers the outer surface side of the suction cup, and a protruding pin portion which protrudes from the hole of the case of the rod is rotatably coupled to the pin In accordance with the rotation operation centered on the pin of the pin connection, the position is displaced to the position of being lowered (locking position) and the standing position (unlocking position) that is raised with respect to the case. The rod is moved in the axial direction with respect to the case by cam-engaging with a predetermined portion of the case, so that the sucker is strongly attracted to the attracted surface by lifting the rod with respect to the case at the lying position. Hold in the state The lock lever that pulls down the rod with respect to the case so that the suction cup can be easily peeled off from the attracted surface, and the position of the case of the rod at both axial positions of the pin of the pin coupling. A projecting portion projecting from the hole is arranged in between, and a pair of convex portions projecting and formed on the outer surface side of the case in a state of facing each other, and one end side is rotatably supported and supported by the case. A swing arm that supports the monitor device on the side, and the lock lever is stored and disposed in a space between the pair of convex portions at the lying position. According to the present invention, the lock lever is stored in the space between the pair of convex portions in the lying position, so that the lock lever is not exposed, and safety can be improved and design can be improved.

  In this invention, when the lock lever is in a state where it is stored in the space between the convex pair at the lying position, the surface of the lock lever forms a continuous surface with the surface of the convex pair. Can be configured. According to this, the lock lever forms a continuous surface with the convex pair when it is stored in the space between the convex pair at the lying position, so that the surface unevenness is reduced, and safety and Design property can be improved more.

  In this invention, on the side surface of at least one convex part of the convex part pair, a position for arranging the pin coupling pin when the rod is in a predetermined position in the movement direction of the rod with respect to the convex part pair; Located on the same axis, the pin is inserted from the outside of the convex portion into a position where the pin for pin connection is arranged to form a pin through hole for realizing the pin connection, and the lock lever is in the lying position In some cases, the pin position of the pin connection and the pin through hole may be arranged non-coaxial with each other. According to this, when the lock lever is in the down position, the pin position of the pin coupling and the pin through hole of the convex portion are arranged non-coaxial with each other, so that the movement of the pin in the axial direction is within the convex portion pair. It is regulated by the wall surface and can prevent the pins from falling off.

  In the present invention, the swing arm and the lock lever may be disposed on opposite sides with respect to the center position of the case. According to this, it is possible to prevent the lock lever and the swing arm from interfering with each other.

  In the present invention, one end of the swing arm may be housed in a space between the pair of convex portions that store the lock lever, and may be rotatably connected to the case. According to this, since the one end part of the swing arm and the lock lever are arranged in the continuous space between the convex part pairs, the design can be further improved.

  An embodiment of the present invention will be described. FIG. 1 is an exploded perspective view of an in-vehicle monitor support device 10 according to this embodiment, and FIG. 2 shows an inner surface (back surface) shape of a case 26 among them. 3 to 11 show a state in use of the in-vehicle monitor support device 10 in which the in-vehicle monitor support device 10 is mounted on the suction surface 35 such as a dashboard with the lock lever 46 in the down position. FIGS. 12-19 shows the state before mounting | wearing the vehicle-mounted monitor support apparatus 10 which mounted this vehicle-mounted monitor support apparatus 10 in the to-be-adsorbed surface 35, such as a dashboard, by making the lock lever 46 into an upright position.

  First, an outline of the in-vehicle monitor support device 10 will be described mainly with reference to FIGS. For example, in FIG. 3, the in-vehicle monitor support device 10 includes a base portion 12, a rotation portion 14, and a monitor attachment portion 16. The base portion 12 is attached to a location (dashboard or the like) where a monitor device is to be installed in the interior of the automobile using a built-in suction cup 30 (FIG. 7). 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 disposed in parallel to the plane to which the lower opening end face 26k of the case 26 of the base portion 12 belongs. The monitor mounting portion 16 includes a mounting base 24 that is connected and supported at the distal end portion of the rotating portion 14 so as to be rotatable in an angle range of 90 ° or more about the rotating shaft 20. The rotating shaft 20 is disposed in parallel to the rotating shaft 18. A monitor device 25 (FIGS. 5, 6, and 7) such as a liquid crystal display constituting a display device of a car navigation system or an in-vehicle television is detachably mounted on the front surface 24a of the mounting base 24.

  According to the above configuration, the rotating unit 14 is manually operated in a state where the base unit 12 is mounted on the suction surface 35 such as a dashboard with the suction cup 30 (FIG. 7) (the state shown in FIGS. 3 to 11). Is rotated around the rotation shaft 18 to adjust the height position of the monitor device 25. At this time, the rotating portion 14 is held at the adjusted rotation angle with respect to the base portion 12 by the frictional force at the connecting portion between the base portion 12 and the rotating portion 14. Further, the vertical angle of the monitor device 25 is adjusted by manually rotating the mounting table 24 about the rotation shaft 20. At this time, the mounting table 24 is held at the adjusted rotation angle with respect to the rotating unit 14 by the frictional force at the connecting portion between the rotating unit 14 and the mounting table 24.

  Next, a detailed configuration of each part of the in-vehicle monitor support device 10 will be described with reference to an exploded perspective view of FIG. 1, a rear view of the case of FIG. 2, and cross-sectional views of FIGS. For example, in FIG. 7, the base portion 12 includes a highly rigid case 26 made of hard synthetic resin, metal, or the like. The case 26 has an outer shape with the heel down, has a circular planar shape (FIG. 5), and has a recess 28 that opens downward. The case 26 accommodates the suction cup 30 in the recess 28 and covers the suction cup 30. The suction surface 30a of the suction cup 30 is directed downward. A polymer gel sheet 33 is detachably attached to the entire suction surface 30a 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.

  The outer peripheral edge 30b of the suction cup 30 is folded back toward the suction surface 30a to form a folded portion 30bb over the entire circumference, as shown in FIG. The outer peripheral edge portion 33a of the polymer gel sheet 33 is sandwiched between the surface side portion 30ba of the outer peripheral edge portion 30b of the suction cup 30 and the folded portion 30bb. According to this, since the outer peripheral edge portion 33a of the polymer gel sheet 33 is sandwiched between the surface side portion 30ba of the outer peripheral edge portion 30b of the suction cup 30 and the folded back portion 30bb, the polymer gel sheet is placed on the suction surface 30a of the suction cup 30. The polymer gel sheet 33 is prevented from being peeled off from the suction surface 30 a of the suction cup 30 when the suction cup 30 is peeled off from the suction target surface 35, even though the 33 is not joined by two-color molding or an adhesive. Further, the folded portion 30bb of the suction cup 30 has a tip portion 30bba that is tapered, whereby the step d between the folded portion 30bb and the polymer gel sheet 33 is relaxed at the position of the tip portion 30bba of the folded portion 30bb. When the level difference d is large, the tip 30bba of the folded portion 30bb pushes the surface 35 to be adsorbed while the suction cup 30 is adsorbed to the surface 35 to be adsorbed, and the polymer gel sheet 33 is adsorbed at a position just inside the step 32. Although it becomes easy to float from the surface 35, since the level difference d is relaxed, the polymer gel sheet 33 is suppressed from floating from the attracted surface 35, and the suction state by the suction cup 30 can be maintained for a long time. Further, since the tip portion 30bba of the folded portion 30bb is tapered, the folded portion 30bb can be easily turned up when the polymer gel sheet 33 is mounted on the suction surface 30a of the suction cup 30, and the polymer gel sheet 33 is mounted. Becomes easier.

  In FIG. 8, the entire periphery of the peripheral surface 30 c of the suction cup 30 is abutted and supported by the peripheral surface 26 a of the case 26. On the outermost peripheral portion of the case 26, an edge portion 26b (FIG. 6 and the like) that surrounds and hides the outer peripheral edge portion 30b of the suction cup 30 protrudes downward. On the lower surface of the case 26, the ridge 26 c is formed in an annular shape over the entire circumference at a position immediately on the inner peripheral side where the outer peripheral edge 30 b of the suction cup 30 sandwiches the outer peripheral edge 33 a of the polymer gel sheet 33 (see FIG. 2) It is formed. According to this, since the protrusion 26c strongly presses the polymer gel sheet 33 against the attracted surface 35 through the suction cup 30 when the sucker 30 is attracted to the attracted surface 35, the suction state by the sucker 30 is maintained for a long time. Can be maintained over time.

  In FIG. 7, a tongue portion 30 d (FIG. 1) is formed so as to protrude sideways from a part of the peripheral edge portion of the suction cup 30. The tongue portion 30d extends out of the case 26 from a notch 26ba (FIG. 8) formed in the edge portion 26b of the case 26. A knob 34 made of hard synthetic resin, metal or the like is attached to the tongue 30d. The knob 34 is attached to the tongue portion 30d by sandwiching the tongue portion 30d between two plate members 34a and 34b (FIG. 1) having a fitting structure and fitting the two plate members 34a and 34b to each other. The knob 34 is used when the in-vehicle monitor support device 10 is removed from the attracted surface 35. That is, when the sucker 30 is attracted to the attracted surface 35 and the knob 34 is picked up and pulled up, a part of the outer peripheral edge 30b of the sucker 30 is peeled off from the attracted surface 35 with the polymer gel sheet 33. From there, air flows between the surface to be adsorbed 35 and the polymer gel sheet 33, the adsorption by the suction cup 30 is released, and the in-vehicle monitor support device 10 is removed from the surface to be adsorbed 35. A through-hole 36 is formed in the knob 34 and the tongue portion 30d so as to pass through both. A screw 38 (FIG. 1) for fixing the knob 34 to the attracted surface 35 is inserted into the through hole 36 as necessary.

  In FIG. 7, a disc 40 made of hard synthetic resin, metal or the like is embedded in the central portion of the suction cup 30. A rod 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. A coil spring 43 is fitted into the rod 42. The rod 42 passes through a hole 44 formed in the center of the upper surface of the case 26 so as to be movable in the axial direction of the rod 42 and protrudes above the case 26. At this time, the coil spring 43 is compressed and sandwiched between the lower surface of the case 26 and the upper surface of the suction cup 30. The coil spring 43 pushes down the central portion of the suction cup 30 with the urging force of the coil spring 43 when the case 26 is pressed against the attracted surface 35 by hand to mount the in-vehicle monitor support device 10 on the attracted surface 35. The air in the space 86 (FIGS. 16 and 19) between the polymer gel sheet 33 and the surface to be adsorbed 35 is discharged to cause the polymer gel sheet 33 to adhere to the surface to be adsorbed 35 over a wide area. The coil spring 43 also serves to assist (or enhance) the click feeling when the lock lever 46 is displaced.

  In FIG. 7, a lock lever 46 is pivotally connected to the upper portion of the protruding portion 42 a protruding from the hole 44 of the case 26 of the rod 42 by a pin 48 so that the lock lever 46 is centered on the pin 48. It can be freely rotated by a manual operation around a rotation axis 50 passing through the center. The lock lever 46 is turned down with respect to the case 26 (locking position) (the position shown in FIGS. 3 to 11) and the raised position (the unlocking position) (the position shown in FIGS. 12 to 19). It is displaced to. The rotation shaft 50 is arranged in parallel with the rotation shafts 18 and 20. The lock lever 46 has a function of raising and lowering the rod 42 with respect to the case 26 by abutment by cam engagement between a cam surface 46d (FIG. 9) formed at the base end portion thereof and the upper surface central portion 26d of the case 26. To do. That is, if the lock lever 46 is operated by hand and is displaced to the down position, the rod 42 is lifted up against the case 26 against the biasing force of the coil spring 43, and the suction cup 30 is strongly adsorbed to the attracted surface 35. Kept in a state. Further, when the lock lever 46 is manually operated and displaced to the standing position, the rod 42 is pulled down with respect to the case 26 by the biasing force of the coil spring 43, and the suction cup 30 can be easily peeled off from the attracted surface 35. become.

  As shown in FIG. 10, the pair of convex portions 26e and 26f are relatively positioned on the upper portion of the case 26 at positions on both sides in the axial direction of the pins 48 constituting the pin coupling and at positions where the projecting portions 42a of the rod 42 are disposed therebetween. The projection is formed integrally with the case 26. The lock lever 46 is stored in the space 52 between the pair of protrusions 26e and 26f in the down position (FIG. 3). At this time, the surface of the lock lever 46 forms a surface continuous with the surfaces of the convex pair 26e, 26f (FIG. 3). That is, the side surface 46b of the lock lever 46 forms a surface that is continuous with the side surfaces 26ea and 26fa of the convex portion pairs 26e and 26f. Further, the upper surface 46e of the lock lever 46 forms a surface that is continuous with the upper surfaces 26eb and 26fb of the convex pair 26e and 26f.

  As shown in FIG. 10, pin through holes 54 and 56 are formed in the side surfaces 26ea and 26fa of the convex pair 26e and 26f, respectively. The pin through holes 54 and 56 are formed to complete the pin connection by inserting the pin 48 constituting the pin connection between the rod 42 and the lock lever 46 from the outside of one of the convex pair 26e and 26f. Is. That is, when the on-vehicle monitor support device 10 is assembled, the pin arrangement hole 42b of the rod 42, the pin arrangement hole 46a of the lock lever 46, and the pin through holes 56 and 54 of the convex pair 26e and 26f are arranged coaxially (FIG. 19). ), The pin 48 is inserted into the pin passage hole 56 (or 54) from the outside of the convex portion pair 26e (or 26f) and accommodated in the pin arrangement holes 42b and 46a of the rod 42 and the lock lever 46. As a result, the rod 42 and the lock lever 46 are pin-coupled by the pin 48. In the pin-coupled state, the pin arrangement hole 42b of the rod 42 has a pin through hole 54, when the lock lever 46 is in the standing position with respect to the case 26 (the position where the rod 42 is pulled down with respect to the case 26). When the lock lever 46 is in the down position (the position where the rod 42 is pulled up with respect to the case 26 (at the time of suction)), the pin through holes 54 and 56 are positioned coaxially with the pin 56. It is located at a shifted position (state shown in FIG. 10). Accordingly, during suction, that is, during use, the movement of the pin 48 in the axial direction is restricted by the inner wall surfaces 26ec and 26fc (FIG. 10) of the pair of protrusions 26e and 26f, thereby preventing the pin 48 from falling out of the pin placement holes 42b and 46a. be able to. When the pin 48 is pulled out from the pin arrangement holes 42b and 46a, the lock lever 46 is displaced to the upright position, and the pin through holes 54 and 56 and the pin arrangement holes 42b and 46a are arranged coaxially (state of FIG. 19). Then, a rod-shaped member is inserted from one outer side of the pin through holes 54 and 56 to push out the pin 48.

  In FIG. 7, in the space 52 between the pair of convex portions 26e and 26f, the base end portion of the swing arm 58 that constitutes the rotating portion 14 at a position opposite to the position where the lock lever 46 is disposed in the longitudinal direction. Is housed. The swing arm 58 and the lock lever 46 are arranged on the opposite sides with respect to the center position of the case 26. The swing arm 58 is rotatably supported by the rotation shaft 18 on the convex pair 26e, 26f by a screw 60. That is, as shown in the exploded view of FIG. 1, the swing arm 58 accommodates the taper bush 62 in the opening on one side of the hole 58 a formed in the base end, and the flat washer in the recess on the surface of the taper bush 62. 64a, a disc spring 64b, and a flat washer 64c are stacked and accommodated (a stack of these three rings is indicated by reference numeral 64).

The laminate is denoted by reference numeral 68). In this state, the base end portion of the swing arm 58 is slid from the lateral direction into the space 52 between the convex pair 26e, 26f. At this time, the rectangular outer portions of the tapered bushes 62 and 66 are accommodated in the rectangular recesses 26g and 26h formed on the inner surface of the space 52 so as not to rotate. In this state, the screw 60 is formed on the side surface of the convex portion 26e from the outside of the convex portion 26e, the hole 26i, the laminated body 68 of the three rings, the tapered bush 66, the hole 58a of the swing arm 58, the tapered bush 62, and three pieces. The swing arm 58 is projected to the outside of the hole 26j through the hole 26j formed on the side surface of the ring stack 64 and the convex portion 26f, and the nut 69 is screwed into the projected end portion so that the swing arm 58 has the convex portion pair 26e, It is connected to 26f by a rotation shaft 18 so as to be rotatable. The turning torque (frictional force) of the swing arm 58 with respect to the convex pair 26e, 26f can be adjusted by the strength with which the screw 60 is screwed into the nut 69.

  The mounting base 24 is rotatably supported by the rotating shaft 20 by a screw 70 at the tip of the swing arm 58. That is, as shown in the exploded view of FIG. 1, the taper bush 72 is accommodated in the opening on one side of the hole 58b formed at the tip of the swing arm 58, and the flat washer 74a is placed in the recess on the surface of the taper bush 72.

A jig 82 for attaching the monitor device is attached to the front surface 24a of the mounting base 24 with screws 84 from the rear side.

  A procedure for mounting the on-vehicle monitor support device 10 having the above configuration to the attracted surface 35 such as a dashboard will be described. Before mounting on the attracted surface 35, the lock lever 46 is set to the upright position in FIGS. When the lock lever 46 is in the standing position, the surface 46 c (FIG. 16) faces the upper surface central portion 26 d of the case 26. In this state, the in-vehicle monitor support device 10 is placed at a desired installation position on the attracted surface 35. When the lock lever 46 is in the upright position, as shown in FIG. 19, the pin arrangement holes 42b and 46a of the rod 42 and the lock lever 46 are coaxial with the pin passage holes 56 and 54 of the convex pair 26e and 26f. Therefore, at this time, the pin 48 can be inserted and removed through the pin arrangement holes 42b and 46a and the pin through hole 54 (or the pin through hole 56). Therefore, at the time of assembly, the lock lever 46 is set in the standing position, and the pin 48 is inserted into the pin arrangement holes 42b and 46a from the pin through hole 54 (or the pin through hole 56). When the pin 48 is removed from the pin placement holes 42b and 46a, the lock lever 46 is placed in the upright position, and a pin-like member is inserted from the outside of the pin passage hole 54 (or the pin passage hole 56) to push out the pin 48.

  From the state of FIGS. 12 to 19 in which the in-vehicle monitor support device 10 is placed at a desired position on the attracted surface 35, the case 26 is pushed down strongly by hand. As a result, the urging force of the coil spring 43 acts on the central portion of the suction cup 30 and the central portion is pushed down, so that the air in the space 86 (FIGS. 16 and 19) between the polymer gel sheet 33 and the attracted surface 35 is made. The polymer gel sheet 33 is discharged and adheres to the attracted surface 35 over a wide area. If the lock lever 46 is pushed down with a finger, the discharge of the air in the space 86 can be further promoted. Further, when the case 26 is pressed down strongly, the protrusion 26c on the lower surface of the case 26 strongly presses the peripheral edge of the polymer gel sheet 33 against the attracted surface 35 via the peripheral edge of the suction cup 30, and the suction cup 30 and the suction cup 30 at the peripheral edge are high. The adhesion between the molecular gel sheet 33 and the polymer gel sheet 33 and the attracted surface 35 is enhanced.

  While the case 26 is strongly pressed down with one hand, the lock lever 46 is rotated to the lying position shown in FIGS. 3 to 7 and FIGS. 46d (FIG. 9) abuts against the central portion 26d of the upper surface of the case 26, and the rod 42 is pulled up along with the central portion of the suction cup 30, so that the space 86 between the polymer gel sheet 33 and the attracted surface 35 is negative pressure. To generate adsorption power. As a result, the in-vehicle monitor support device 10 is strongly attached to the attracted surface 35. In the state where the space 86 is negatively pressured, the protrusion 26c strongly presses the polymer gel sheet 33 against the attracted surface 35 via the suction cup 30 due to the negative pressure, so that the suction state by the suction cup 30 is maintained for a long period of time. When the lock lever 46 is in the down position, it is stored in the space 52 between the convex pair 26e and 26f (FIG. 3), and the surfaces 46b and 46e of the lock lever 46 are the surfaces 26ea and 26eb of the convex pair 26e and 26f. , 26fa and 26b are formed. Therefore, the base portion 12 has less surface irregularities, and the safety and the design are good. In the state of use in which the lock lever 46 is in the down position, as shown in FIG. 10, the pin arrangement holes 42b and 46a of the rod 42 and the lock lever 46 are displaced from the pin through holes 54 and 56 of the convex pair 26e and 26f. In a non-coaxial position. Therefore, since the pin 48 accommodated in the pin arrangement holes 42b and 46a is restricted from moving in the axial direction by the inner wall surfaces 26ec and 26fc of the convex pair 26e and 26f, the pin 48 falls out of the pin arrangement holes 42b and 46a. Is prevented.

  In a state where the in-vehicle monitor support device 10 is attached to the attracted surface 35, the driver or the like can manually adjust the height position of the monitor device 25 by rotating the swing arm 58 around the rotation shaft 18. it can. Further, the driver or the like manually rotates the monitor mounting portion 16 about the rotation shaft 20 to adjust the vertical angle of the monitor device 25. Therefore, the monitor device 25 is held in a predetermined posture with respect to the attracted surface 35 by the cooperation of the rotation of the swing arm 58 about the rotation shaft 18 and the rotation of the monitor mounting portion 16 about the rotation shaft 20. The height position of the monitor device 25 can be adjusted while maintaining the above. When the on-vehicle monitor support device 10 is removed from the attracted surface 35, the knob 34 is picked up with a finger and pulled up. As a result, a part of the outer peripheral edge portion 30b of the suction cup 30 is peeled off from the attracted surface 35 with the polymer gel sheet 33, and air flows between the attracted face 35 and the polymer gel sheet 33 from there. The suction due to is released, and the in-vehicle monitor support device 10 is removed from the attracted surface 35 such as a dashboard.
