  • Patent number: 12221170
    Abstract: In a deflector device, when an external force acts on an deflector body while at a deployed position such that the deflector body is rotated in a stowing direction, even if further rotation of the deflector body in the stowing direction is restricted, the deflector body is rotated to the deployed position by an urging force of a torsion coil spring when the external force acting on the deflector body is released. This enables the deflector body to be rotated to the deployed position from anywhere over an entire rotatable range in the stowing direction by the urging force of the torsion coil spring. Thus, the torsion coil spring is able to rotate the deflector body to the deployed position in a suitable manner.

  • Publication number: 20240343323
    Abstract: An airflow deflector has: an airflow deflecting body supported at a vehicle body of a vehicle so as to be able to rotate between an extended position at a lower side of the vehicle body of the vehicle and a retracted position at the vehicle body side; a driving section generating driving force for rotating the airflow deflecting body; a detecting device detecting a rotational position of the airflow deflecting body irrespective of operation of the driving section; and a rotational position recognizing section that, when judging that the rotational position detected by the detecting device has not changed throughout a threshold time period, judges that the airflow deflecting body has stopped rotating.

  • Publication number: 20240051625
    Abstract: In a rectifying mechanism, a left actuator and a right actuator are independently controlled based on a pressure of traveling wind to a vehicle, and a rotation amount of a left deflector and a rotation amount of a right deflector are independently adjusted. Therefore, positions of the deflectors can be appropriately adjusted according to a situation of the vehicle.

  • Publication number: 20230242184
    Abstract: In a deflector device, a magnet is rotated when a deflector body is rotated, and a magnetic sensor also detects a rotational position of the magnet. Moreover, an interior of a housing body is partitioned by a motor base into a vehicle width direction outside of the interior and a vehicle width direction inside of the interior, with the magnet housed on the vehicle width direction outside of the interior of the housing body. The magnetic sensor is housed on the vehicle width direction inside of the interior of the housing body. This accordingly enables foreign matter ingression from the vehicle width direction outside of the interior of the housing body into the vehicle width direction inside thereof to be suppressed by the motor base, enabling foreign matter to be suppressed from reaching the magnetic sensor.

  • Publication number: 20230143257
    Abstract: A flow deflecting device includes a flow deflecting body configured to be deployed to a front side of a front wheel and configured to be retracted in a vehicle body; a rotational mechanism, whereby the flow deflecting body is rotatable in an engaged state at the rotational mechanism; and a limiting mechanism, whereby rotation of the flow deflecting body is limitable in an engaged state at the limiting mechanism. In a case in which the flow deflecting body in a deployed position is acted upon by an external force, engagement with the rotational mechanism is released, and the flow deflecting body is rotated in the retraction direction in the engaged state at the limiting mechanism. In a case in which the flow deflecting body in a retracted position is acted upon by an external force, engagement with the limiting mechanism is released, and the flow deflecting body is rotated in the retraction direction in the engaged state at the rotational mechanism.

  • Patent number: 10516264
    Abstract: Power can be supplied to a smart device without affecting control of a cash drawer. A printer 1 capable of connecting to a smart device 2 and a cash drawer 3 has a wireless communicator 16 for communicating with the smart device 2, a drawer kick connector 18 that connects to the drawer 3, a power circuit 14, and a controller 11. When a command instructing control of the drawer 3 is received from the smart device 2 by the wireless communicator 16, the controller 11 stops the supply of power from the power circuit 14 to the smart device 2; and when control of the drawer 3 ends, the controller 11 starts supplying power to the smart device 2.

  • Patent number: 10436414
    Abstract: In a door mirror device for a vehicle, a projector protrudes out toward a lower side from a circuit board, and the projector projects a pattern onto a ground surface. Moreover, illuminating LEDs and guide bodies are fixed to a lower surface of the circuit board. Due to the illuminating LEDs generating lights and the guide bodies guiding these lights, the guide bodies irradiate the lights from lower ends, and the ground surface is illuminated. Here, the lower ends of the guide bodies are disposed further toward a lower side than the projector. Therefore, shadows, which are due to the projector, arising in lights that illuminate the ground surface can be suppressed.

  • Patent number: 10300841
    Abstract: In a vehicle lamp device, light emitted by a LED enters a concentration element of a lens and is irradiated from an irradiating face of the concentration element. The reflecting face of the concentration element surrounds a central axis of the concentration element. Light that enters the concentration element is reflected by the reflecting face toward a central axis side of the concentration element, and light reflected by the reflecting face is irradiated from the irradiating face. The concentration element is thus able to efficiently concentrate light emitted by the LED.

  • Publication number: 20170371235
    Abstract: A projection mechanism of a vehicle projection device projects a graphic of a graphic film toward an outer side of a vehicle. A projection direction of the graphic from the projection mechanism is inclined with respect to a rotation axis of the projection mechanism. Thus, by manually rotating a dial to rotate the projection mechanism about the rotation axis, the projection direction of the graphic from the projection mechanism can be altered, and the projection position of the graphic from the projection mechanism can be altered.

  • Publication number: 20170368985
    Abstract: A vehicle projection device projects a graphic of a film body housed in a housing toward an outer side of the housing. It is possible to detach the film body toward an exterior of the housing via a communication hole in the housing by gripping a grip portion of the film body. This thereby enables the film body to be detached toward the exterior of the housing.

  • Publication number: 20170349088
    Abstract: In a vehicle door mirror device, a projection device projects a graphic from a graphic film. The projection device is inserted into a cap in a state in which a holding tube of the cap has been inserted into a through hole in a visor, and the holding tube is held between a peripheral face of the through hole and a protrusion portion of the projection device. The projection device is thus installed at the visor in a manner retained by the cap alone. This thereby enables easy installation of the projection device to the visor.
