  Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. FIG. 1 is a schematic view showing a front glass 1 of an automobile and its surroundings. A shade storage box 4 is erected on a dashboard 2 in the vicinity of the side edge of the front glass 1, and an upper end portion of the storage box 4 is fixed to a ceiling 18 of the automobile. In the shade storage box 4, a shade supply unit 5 in which the shade 3 is wound around the winding shaft 7 is stored with the winding shaft 7 of the shade 3 being vertical. . Then, the shade 3 is fed out from the shade supply unit 5 in the horizontal direction by forward and reverse rotation of the winding shaft 7, and the shade 3 is wound up in the shade supply unit 5.

  A wire 8 is wound around the upper end and the lower end of the winding shaft 7 of the shade supply unit 5. In addition, a reel 9 a is suspended from the ceiling 18 by a support column 10 in the vicinity of the side of the front glass 1 opposite to the shade supply unit 5. Further, a reel 9b that is erected by a support column 10 on the dashboard 2 is disposed immediately below the reel 9a.

  The wire 8 is fed out from the upper end of the winding shaft 7 of the shade supply unit 5 in the horizontal direction and is wound around the reel 9a across the near side near the upper edge of the front glass 1. . The wire 8 descends from the reel 9a to the reel 9b and is wound around the reel 9b. Further, the wire 8 moves in the horizontal direction from the reel 9 b and crosses the near side near the lower edge of the front glass 1 and is wound around the winding shaft 7 of the shade supply unit 5. As described above, the wire 8 moves in the horizontal, vertical, and horizontal directions in the upper, right, and lower portions of the front glass at the indoor side position of the front glass 1, respectively. It is driven by forward and reverse rotation of the rotating shaft (winding shaft 7) in the section 5. That is, the wire 8 continues to the upper end of the shade supply unit 5, the reel 9a, the reel 9b, and the lower end of the shade supply unit 5, and the winding shaft 7 of the shade supply unit 5 has a wire at its lower end. When the wire 8 is rotated in the winding direction, the wire 8 moves to the left (shade supply unit 5 side) in the lower part of the front glass 1, and is fed out from the shade supply unit 5 to the right in the upper part of the front glass 1. Direction). On the other hand, when the shade supply unit 5 rotates in the direction of winding the wire 8 at the upper end of the winding shaft 7 of the shade supply unit 5, the wire 8 moves toward the shade supply unit 5 on the upper front side of the front glass 1. Then, the wire 8 is pulled so as to move so as to be fed out toward the reel 9b in front of the lower portion of the front glass 1.

  The shade 3 has a sheet shape. And the upper edge part of the sheet-like shade 3 is being fixed to the wire 8 withdrawn / inserted in the upper end part of the shade supply part 5 with the fixing tool 11. FIG. On the other hand, a ring-shaped ring member 12 is fixed to the lower edge portion of the shade 3 at an appropriate length interval. The ring member 12 fits the wire 8 so that the wire 8 passes through the inside of the ring member 12. It has become. Accordingly, the lower edge portion of the shade 3 is constrained by the wire 8 that moves in the horizontal direction on the lower edge portion of the front glass 1, and is positioned near the lower portion of the front glass 1. Therefore, the movement of the wire 8 is not restricted by the position of the lower edge portion of the shade 3.

  The winding shaft 7 of the shade supply unit 5 is connected to a motor 14 via a connecting member 13. Then, when the motor 14 is driven to rotate in the forward and reverse directions, the winding shaft 7 is rotated in the forward and reverse directions, and the wire 8 is fed out from the shade supply unit 5 and wound into the shade supply unit 5.

  The motor 14 is driven forward and reverse by the control unit 15. An on / off signal of the ignition key 16 is input to the control unit 15. The control unit 15 controls the motor 14 as described later by turning on and off the ignition key 16. In addition, a setting signal from the setting unit 17 is input to the control unit 15. When the setting signal is on, the control unit 15 performs motor control by turning on and off the ignition key 16. However, when the setting signal is off, the control unit 15 does not perform motor control by turning on and off the ignition key 16.

  Next, the operation of the electric car shade configured as described above will be described. When there is a possibility that the interior of the vehicle becomes hot due to sunlight, such as in summer, the driver selects to turn on the setting signal of the setting unit 17. In this case, first, the vehicle can be operated in a state where the shade 3 is wound in the shade supply unit 5. That is, the control unit 15 sets the operating position of the motor 14 in the state in which the shade 3 is stored in the shade supply unit 5 when the ignition key 16 is turned on and operation is possible. Thereafter, when the operation is stopped and the driver turns off the ignition key 16, the control unit 15 drives the motor 14 to rotationally drive the winding shaft 7 via the connecting member 13, so that the shade supply unit 5 The wire 8 is sent out from the upper end. At this time, the winding shaft 7 in the shade supply unit 5 operates to draw the wire 8 into the shade supply unit 5 at the lower end portion of the shade supply unit 5, and the shade supply unit 5 is pulled by the wire 8. The wire 8 comes out from the upper end of 7 toward the reel 9a. Then, the upper wire 8 moves toward the reel 9a, and the shade 3 is also fed out from the shade supply unit 5 and moves toward the right side of the front glass 1. However, the lower wire 8 moves toward the shade supply unit 5. Move. However, the lower portion of the shade 3 is located along the vicinity of the lower portion of the front glass 1 via the wire 8 and the ring member 12, but the wire 8 only passes through the ring member 12, so that the lower wire The movement of 8 does not hinder the advance movement of the shade 3. When the shade 3 reaches the reel 9a, the control unit 16 stops the motor 14 and stops in a state where the shade 3 covers most of the area of the front window glass 1. As a result, the shade 3 prevents external light such as infrared light from entering the vehicle and prevents the interior of the vehicle from becoming hot.

  On the other hand, when the driver tries to start the automobile and turns on the ignition key 16, the control unit 15 reversely rotates the motor 14 and winds the wire 8 from the upper end of the shade supply unit 5 into the shade supply unit 5. Thus, the winding shaft 7 is rotated in the reverse direction. Thereby, the wire 8 moves to the shade supply unit 5 side at the upper end of the shade supply unit 5, the shade 3 fixed to the wire 8 part moves backward, and the front window glass 1 is released from the shade 3. The Thereby, driving | operation becomes possible. Also in this case, the wire 8 moves toward the reel 9b at the lower end of the shade supply unit 5, but the retreating shade 3 is connected to the wire 8 by the ring member 12 at the lower edge thereof, so that the front glass The movement of the wire 8 at the lower edge does not hinder the movement of the shade 3. It should be noted that when the light shielding by the shade 3 is not necessary, such as in the winter season, the setting signal of the setting unit 17 is turned off, so that the square-opening operation of the shade 3 in conjunction with the ignition key 16 is not performed.

  According to the present invention, the shade 3 can be automatically moved to the shielding position and the opening position of the front window glass 1 in conjunction with the on / off of the ignition key 16. The shade 3 is stored in the shade storage box 4 in the vicinity of the front window glass 1 when not in use, so that it does not interfere with the interior space of the automobile. In addition, since the shading operation and the opening operation by the installation of the shade 3 are linked with the on / off of the ignition key 16 for starting / stopping the operation of the vehicle, the shading and opening processing is performed without performing any special operation. Can do.

  As the shade 3 for shading, light shielding performance is required. In addition, if a material with excellent printing performance is used, various designs are printed on the shade 3, and the car is used in a parking lot. When parked and illuminated, the symbol can be displayed externally. Thereby, the appearance of the appearance of the car at the time of parking can be improved, or an advertisement function can be provided. In the present invention, the phrase “shade has printability” means that printing is possible or that symbols can be arbitrarily displayed and attached with ink.

  Moreover, in this embodiment, the shade supply part 5 is arrange | positioned along the vertical edge of the window glass 1, and the shade 3 was able to advance / retreat in a horizontal direction, The invention is not limited to this, and for example, the shade supply unit 5 may be installed horizontally on the dashboard, and the wire 8 may be extended and transferred in the vertical direction. In this case, the shade 3 moves upward from the dashboard to cover the window glass 1, moves downward, and is stored in the shade supply unit 5. In addition, the shade supply part 5 can be installed in arbitrary positions on the four edges of the front glass 1.

  According to the present invention, it becomes possible to cover the front glass of a vehicle with a shade in conjunction with the operation of the ignition key of the vehicle, and it is possible to easily prevent high temperatures in the vehicle in summer.
