  The portable device fixing device 1 according to the present embodiment is a device for fixing a portable device P such as a small television receiver or a car navigation device to a vehicle seat, and is provided at the upper end of the seat back 90 of the vehicle seat. Is provided. The portable device fixing device 1 includes a fixing unit 10 and a support unit 20 that rotatably supports the fixing unit 10.

  The fixing unit 10 has a device holding mechanism that holds the portable device P on the side surface 101 side of the plate-like main body portion. The fixing portion 10 is formed in a size that can be accommodated in a recess 91 formed on the back surface of the seat back 90 of the vehicle seat. Specifically, the fixed portion 10 is formed slightly smaller than the concave portion 91. When the fixing portion 10 is accommodated in the recess 91, a state in which a minute gap is generated between the outer periphery of the fixing portion 10 and the inner periphery of the recess 91 (a state in which there is almost no gap between the two). Further, the recess 91 formed on the back surface of the seat back 90 is formed at the upper end portion of the seat back 90 and its upper part is open. The fixed portion 10 is set to a size such that the upper end of the fixing portion 10 is substantially the same height as the upper end of the seat back 90 in a state where it is accommodated in the recess 91.

  The device holding mechanism constructed on the one side surface 101 side of the fixing unit 10 is a configuration for fixing the portable device P on the one side surface 101. As this apparatus holding mechanism, the structure which provided the screw member 11 which penetrates the fixing | fixed part 10 can be illustrated so that it may be illustrated. A long hole 12 extending in the front-rear direction is formed in the fixing portion 10, and a screw member 11 is inserted through the long hole 12. Many portable devices P have screw holes (female screws) formed on the outside of the device, and the portable device P is fixed to the fixing portion 10 by screwing the screw member 11 into the screw holes. Since the screw member 11 is inserted through the long hole 12, the screw member 11 is slidable in the front-rear direction. That is, the device holding mechanism is constructed to be slidable in the front-rear direction on the one side surface 101 of the fixed portion 10. Since the device holding mechanism has such a configuration, in this embodiment, the mounting position of the portable device P on the fixed portion 10 is moved in the front-rear direction (the fixed portion 10 is moved to an arbitrary position within the slidable range). Can be fixed). Since the screw hole formed in the portable device P may vary in size depending on the device, the screw member 11 is configured to be detachable from the long hole 12. That is, it is possible to attach the screw member 11 corresponding to the screw hole formed in the portable device P.

  A cover member 13 that covers the screw member 11 is provided on the surface (back surface) opposite to the one side surface 101 on which the device holding mechanism in the fixing unit 10 is constructed. The cover member 13 is provided so as to be openable and closable with respect to the main body portion of the fixed portion 10 by, for example, an integral hinge. When the screw member 11 is not operated, the screw member 11 can be covered with the cover member 13, so that the appearance is good. The back surface of the fixing portion 10 including the cover member 13 has a shape that is continuous with the back surface of the seat back 90 in a state where the fixing portion 10 is accommodated in the recess 91. That is, a virtual surface obtained by extending the back surface of the seat back 90 in the direction of the concave portion 91 as it is matches the back surface of the fixed portion 10. Therefore, in a state where the fixing portion 10 is accommodated in the recess 91 and the cover member 13 is closed, the back surface of the seat back 90 and the back surface of the fixing portion 10 are flush with each other.

  In the recess 91, a terminal 911 used for supplying power to the portable device P is provided. Each drawing showing the terminal 911 shows only one terminal 911 for easy understanding of the drawing. However, in order to increase the types of portable devices P that can be used, various types of terminals 911 are provided in the recess 91 in advance. Is preferably provided.

  The fixed portion 10 having such a configuration is attached to the vehicle seat via the support portion 20. Specifically, the support portion 20 is constructed on both sides of the lower end portion of the recess 91, and connects the both ends of the lower end portion of the recess 91 and the lower end portion of the fixing portion 10. The support portion 20 supports the fixed portion 10 so as to be rotatable. That is, the fixed portion 10 tilts toward the back side (rear) of the vehicle seat with the lower end portion connected to the support portion 20 as a fulcrum. If it sees for the person who seats on the back side of the vehicle seat provided with the portable apparatus fixing device 1 (person who sits on a rear seat), the fixing | fixed part 10 will incline to the near side of self. Further, in the fixing unit 10 that is rotatably supported by the support unit 20 in this way, the one side surface 101 to which the portable device P is fixed is the same as the bottom surface of the recess 91 in a state where the fixing unit 10 is accommodated in the recess 91. opposite. Therefore, when the fixing portion 10 is tilted rearward, the one side surface 101 to which the portable device P is fixed faces upward. In other words, the fixed portion 10 is rotatably supported through the support portion 20 from a state in which it is accommodated in the recess 91 to a predetermined state in which the one side surface 101 is directed upward. Here, “upward” does not mean a state in which one side surface 101 is orthogonal to the vertical direction (gravity direction), but a state in which one side surface 101 faces approximately upward (specifically, the back surface of the seat). And an angle formed by one side surface 101 of the fixed portion 10 is a predetermined state in a range of 0 degrees to 180 degrees). In the present embodiment, the angle (maximum angle) formed between the back surface of the seat and the one side surface 101 of the fixing portion 10 when the fixing portion 10 is most inclined is approximately 90 degrees.

  In addition, the portable device fixing device 1 has an angle holding mechanism that holds the fixing portion 10 at a predetermined angle with respect to the vehicle seat. An example of such an angle holding mechanism will be briefly described below with reference to FIGS. The angle holding mechanism shown in FIGS. 7 to 9 is provided in a support portion 20 that rotatably supports the fixing portion 10, and includes a cam member 21, a ball 22, a spring plate 23, and a holding release member 24. A tilting member 25, a guide plate 26, and a leaf spring 27.

  The cam member 21 is a member having an outer periphery formed in a corrugated shape, and rotates with the rotation of the fixed portion 10. A ring member (not shown) is provided on the outer periphery of the cam member 21, and the outer periphery forms a space together with the cam member 21 having a corrugated shape. The space is wide toward one side of the rotation direction (direction in which the fixed portion 10 is tilted; the direction of arrow B) and wide toward the other side (direction in which the fixed portion 10 is erected; direction of arrow A). It is narrow. A ball 22 is accommodated in this space. The spring plate 23 urges the ball 22 in the direction in which the space is narrow (the direction of the arrow A). The holding release member 24 has a protrusion 241 that enters the space, and is biased in the direction of arrow A by a tension spring 243. When the holding release member 24 rotates in the direction of arrow B against the urging force of the tension spring 243, the protrusion 241 entering the space presses the ball 22 in the direction in which the space is wide (direction of arrow B). The tilting member 25 is urged to rotate in the direction of arrow C by a torsion coil spring (not shown). When the tilting member 25 rotates in the direction opposite to the direction of arrow C against the urging force of the torsion coil spring, it acts on the arm 242 of the holding release member 24 to rotate the holding release member 24 in the direction of arrow B. Let The guide plate 26 has a guide portion 261 that protrudes radially outward. Even if the fixing portion 10 is rotated, the guide plate 26 does not rotate (the position in the rotation direction of the guide portion 261 does not change). When the tilting member 25 is on the outside of the guide portion 261 of the guide plate 26, the tilting member 25 acts on the arm 242 of the holding release member 24. The leaf spring 27 is provided at a position where the outer peripheral edge of the guide portion 261 of the guide plate 26 is extended in the direction of arrow B as it is. The leaf spring 27 has an elastic force that does not deform even when the tilting member 25 biased by the torsion coil spring acts on the outer surface thereof.

  The movement of the angle holding mechanism having such a configuration will be described together with the tilting operation of the fixing unit 10. When the concave portion 91 is tilted from the state in which the fixing portion 10 is accommodated in the concave portion 91 (the fixing portion 10 is in the standing state), the tilting member 25 rides on the outside of the guide portion 261 of the guide plate 26 as shown in FIG. Is in a state. Therefore, the tilting member 25 acts on the arm 242 of the holding release member 24 and rotates the holding release member 24 in the direction of arrow B. Therefore, the ball 22 is pressed in the direction in which the space is wide (the direction of the arrow B) by the protrusion 241 of the holding release member 24. Thus, if the ball 22 is positioned at a wide portion, the cam member 21 is not locked by the ball 22. Therefore, the fixed part 10 easily tilts.

  When the fixing portion 10 is gradually tilted as it is, the tilting member 25 moves while riding on the outside of the guide portion 261 of the guide plate 26 and the outside of the leaf spring 27. Then, as shown in FIG. 8, when the fixed portion 10 is in the most tilted state, the state of riding on the outside of the leaf spring 27 of the tilting member 25 is eliminated, and the tilting member 25 is calibrated by the biasing force of the torsion coil spring. Move inward direction. Then, the state in which the tilting member 25 acts on the arm 242 of the holding release member 24 is canceled, and the holding release member 24 is rotated in the direction of arrow A by the tension spring 243. Therefore, since the pressing state of the ball 22 by the protrusion 241 of the holding release member 24 is canceled, the ball 22 is urged by the spring plate 23 in the direction in which the space is narrow (direction of arrow A). As a result, when the ball 22 moves in the direction in which the space is narrow and is caught between the cam member 21 and the ring member located on the outer periphery thereof, the rotation of the cam member 21 in the arrow B direction is prevented. It becomes. That is, the rotation of the fixed portion 10 in the arrow B direction is prevented (the brake is applied to the fixed portion 10). Thus, within the range in which the tilting member 25 is located inside the leaf spring 27 from the state in which the fixing portion 10 is most inclined (portion indicated by K in FIGS. 7 to 9; the angle of the portion is θ degrees). , It can be held at any position (any angle).

  When the fixing portion 10 is further rotated in the A direction, the tilting member 25 pushes the leaf spring 27 outward in the radial direction and rides on the outside of the guide portion 261 of the guide plate 26 again. As a result, the state where the rotation of the fixing portion 10 in the direction of arrow B is prevented (the state where the fixing portion 10 is braked) is eliminated.

  As described above, in the present embodiment, the angle holding mechanism causes the angle between the back surface of the seat and the one side surface 101 of the fixing portion 10 to be approximately 90 degrees (the state in which the fixing portion 10 is most inclined) [90]. Within the range of −θ] degrees, the fixed portion 10 can be held at a predetermined angle. That is, the angle holding mechanism is a continuously variable brake mechanism that can adjust the angle of the fixed portion 10 steplessly within the range. The smaller the angle formed between the seat back surface and the one side surface 101 of the fixing portion 10, the more the portable device P tilts in the direction in which the upper end moves forward, and the angle formed between the seat back surface and the clamping portion of the first fixing portion 10. The smaller the is, the more the portable device P tilts in the direction in which the upper end moves backward. By adopting such an angle holding mechanism, it is possible to adjust the mounting angle of the portable device P so that the portable device P can be used easily regardless of the inclination angle (reclining state) of the vehicle seat. .

  The configuration of the angle holding mechanism is merely an example, and another configuration may be adopted as long as the fixing unit 10 can be held at a predetermined angle. For example, it is good also as a structure which can adjust the angle of the fixing | fixed part 10 in steps using a ratchet mechanism.

  According to the portable device fixing apparatus 1 according to the present embodiment described above, the following operational effects can be obtained. First, when the portable device P is not used, the fixing portion 10 to which the portable device P is fixed can be accommodated in the recess 91 of the seat back 90, so that the fixing portion 10 does not get in the way when getting on and off. Moreover, since the back surface of the fixing portion 10 is shaped along the back surface of the seat back 90, the state in which the fixing portion 10 is accommodated in the recess 91 may be clearly seen. Furthermore, since the fixing | fixed part 10 can be easily accommodated in the recessed part 91 by rotating the fixing | fixed part 10 via the support part 20, it is convenient.

  In addition, since the portable device fixing device 1 according to the present embodiment is provided on the vehicle seat, the angle of the fixing portion 10 changes depending on the inclination angle (reclining state) of the vehicle seat. In the present embodiment, the angle holding mechanism that holds the fixed portion 10 at a predetermined angle with respect to the vehicle seat and the device holding mechanism are configured to be slidable in the front-rear direction, and therefore, regardless of the inclination angle of the vehicle seat. In other words, the angle of the fixing unit 10 and the mounting position of the portable device P can be adjusted so that the portable device P can be easily used. For example, if the portable device P is a television receiver, the angle and position of the screen can be freely adjusted so that the video can be easily viewed.

  Further, the portable device P with respect to the fixed portion 10 can be adjusted by utilizing the fact that the angle of the fixed portion 10 can be adjusted by the angle holding mechanism and that the device holding mechanism (screw member 11) is configured to be slidable in the front-rear direction. By adjusting the mounting angle and mounting position, the portable device P can be mounted in a more stable state. Specifically, as shown in FIG. 6, the portable device P can be supported in a state of being in contact with the vehicle seat. With such a configuration, the portable device P is supported at two points by the device holding mechanism of the fixing unit 10 and the vehicle seat, and the mounting state of the portable device P is stable in an in-vehicle environment where vibration or the like occurs. To do.

  Moreover, since the lower end part of the fixing | fixed part 10 is rotatably supported by the support part 20, the space which attaches the portable apparatus P in the fixing | fixed part 10 is large.

  In addition, the recess 91 formed on the back surface of the seat back 90 is formed at the upper end of the seat back 90 and the upper part thereof is open, and the upper end of the fixed portion 10 is accommodated in the recess 91. The size is set to be approximately the same height as the upper end of the seat back 90. Therefore, in a state where the fixing portion 10 is accommodated in the recess 91, the upper end of the fixing portion 10 is exposed at the upper end of the seat back 90, and therefore the fixing portion 10 is easily tilted backward (the upper end of the fixing portion 10). The fixing portion 10 can be easily tilted by hooking a hand on the head).

  As mentioned above, although embodiment of this invention was described in detail, this invention is not limited to the said embodiment at all, A various change is possible in the range which does not deviate from the summary of this invention.

  For example, in the above-described embodiment, it has been described that the portable device fixing device 1 is provided on the seat back 90 of the vehicle seat, but may be provided on the headrest of the vehicle seat.

  Moreover, in the said embodiment, although the apparatus holding mechanism demonstrated that it was the structure by which the portable apparatus P was fixed to the fixing | fixed part 10 via the screw member 11 penetrated by the long hole 12, of such an apparatus holding mechanism, The configuration is an example. As a modification of the device holding mechanism, a configuration as shown in FIG. 10 can be considered. In this modification, a base plate 51 is slidable in the front-rear direction on one side surface 101 of the fixed portion 10, and a fixed plate 52 and a movable plate 53 are provided on the base plate 51. The movable plate 53 is attached to the fixed plate 52 via a screw member 54, and moves in the front-rear direction with respect to the fixed plate 52 by rotating the screw member 54. With such a configuration, the portable device P can be sandwiched and held between the fixed plate 52 and the movable plate 53. Therefore, the thickness of the portable device P is small (in FIG. 10, the relatively thick portable device P1 is shown). The portable device P can be fixed to the fixing portion 10 regardless of the state (a) in which the portable device P2 is fixed and the state (b) in which the relatively thin portable device P2 is fixed). Versatility is improved.
