Door mirror
First Claim
1. In a door mirror for use in a motor vehicle, the combination which comprises:
- a stay having a shaft portion and secured on an outer surface of a door of a vehicle,a mirror visor pivotally supported on the stay so that the visor may rotate about the shaft portion on the stay between a projected and a retracted position,an electrical motor mounted on the visor;
power transmission means for transmitting the power developed by the motor to the stay to pivotally move the visor between the projected and retracted position with respect to the stay, the power transmission means including a first gear connected with the motor and a second gear secured on the shaft portion of the stay and arranged to engage the first gear, whereby the motor when driven turns the first gear together with the visor around said second gear and, hence, around the shaft portion of the stay so that the visor moves between the retracted and projected positions;
a control circuit for selectively driving the motor in a desired rotational direction, the control circuit including a manually operable switch and an actuating knob for the switch, the manually operable switch being arranged to drive the motor in a desired direction when the actuating knob is operated in a corresponding direction so that the visor is moved from the retracted position to the projected position or from the projected position to the retracted position, anda rotary switch mounted on the shaft portion of the stay and coupled to the control circuit, the rotary switch being responsive to the movement of the visor to stop the motor when the visor has reached one of the retracted and projected positions.

Abstract
The disclosure relates to a door mirror for use in a motor vehicle having a door mirror positioning device for controlling the attitude of the mirror visor with respect to the door from the interior of the motor vehicle through remote control. The device includes a first switching arrangement for selectively driving an electrical motor accommodated in the visor in a desired rotational direction to move the visor to an opened (projected) or closed (retracted) position from the closed or opened position, and a second switching arrangement for stopping automatically the rotation of the motor at a time when the visor reaches one of the opened and closed positions, whereby the operation of the device can be facilitated.

2. In a door mirror for use in a motor vehicle, the combination which comprises:
-
a stay having a shaft portion and secured on an outer surface of a door of the vehicle, a mirror visor pivotally supported on the stay so that the visor may rotate about the shaft portion of the stay between a projected and a retracted position, a source of DC power for the motor; power transmission means for transmitting the power developed by the motor to the stay to pivotally move the visor between the projected and retracted position with respect to the stay, the power transmission means including a first gear connected with the motor and a second gear secured on the shaft portion of the stay and arranged to engage the first gear, whereby the motor when driven turns the first gear together with the visor around said second gear and, hence, around the shaft portion of the stay so that the visor moves between the retracted and projected positions; a switching circuit for connecting the motor to the power source and for selectively reversing the polarity of power applied to the motor to selectively drive the motor in a desired direction; a manually operable switch for operating the switching circuit to move said visor from the retracted position to the projected position or from the projected position to the retracted position; and a rotary switch mounted on the shaft portion of the stay and coupled to the switching circuit, the rotary switch being arranged to sense the pivotal movement of visor, and to be turned to one state when the visor is in one of the retracted and projected positions, and to be turned to another state during the time that the visor passes an intermediate position between the retracted and projected positions, whereby the operation of said switching circuit and the motor stops when the rotary switch is turned to said one state. - View Dependent Claims (3, 4, 5, 6)

7. In a door mirror for use in a motor vehicle which comprises a stay secured on an outer surface of a door and pivotably supports a mirror visor thereon with the stay having a shaft portion about which the visor rotates, the combination which comprises:
-
an electrical motor mounted on the visor a source of DC power for the motor; power transmission means for transmitting the power developed by said motor to said stay to pivotally move said visor between a projected and retracted position with respect to said stay, the power transmission means including a first gear connected to said motor and a second gear secured on the shaft portion of the stay for engaging the first gear, whereby when the motor is driven, the first gear turns around said second gear and hence, around the shaft portion of said stay, control means connected between the power source and the motor for applying power to the motor with a selected polarity to cause the motor to move said visor to one of the retracted and projected positions from the other position, and a rotary switch mounted on the shaft portion of the stay and connected to the control means, the rotary switch being arranged to sense the pivotal movement of said visor and to be turned to one state when the visor has reached the retracted or projected position to thereby terminate the application of power to the motor and stop movement of the visor. - View Dependent Claims (8)
