Abstract
Abstract An electric remote-controlled rearview mirror assembly for a vehicle includes a mirror pivotally supported by a three point pivot connection of which the center pivot connection is stationary to permit angular movement of the mirror therearound. The remaining two pivot connections are spaced a predetermined angle from each other about the center pivot connection and are connected to rod members which are individually actuatable for longitudinal movement by at least one electric reversible motor to thereby positively angularly adjust the mirror around the center pivot connection. The drive of the motor is transmitted to the rod members through nut members. Either one of the rod members and the nut members is made of an elastic material whereas the other of the rod members and the nut members is made of a rigid material. The use of pairs of pinch roller instead of the nut members is also disclosed.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
346 words
An electric remote control rearview mirror assembly comprising: a mirror unit including a mirror support plate and a mirror having a reflective surface and a backside and supported by the mirror support plate with the backside facing thereto; a support casing positioned on one side of the mirror support plate remote from the mirror; a spherical mounting member positioned between the mirror unit and the support casing for clamping the mirror support plate thereon for pivotal movement around horizontal and vertical axes; a pair of sockets defined in the mirror support plate in spaced relation to the spherical mounting member and spaced a predetermined angle from each other with respect to the spherical mounting member; a pair of elastic rod members formed of elastic material, each said elastic rod member comprising a stem portion, an end fixture portion fitted in a respective said socket, and a neck portion between said stem portion and said fixture portion; a pair of drive members formed of rigid material and rotatably supported inside said support casing, each said drive member being held in driving engagement with said stem portion of a respective said rod member at a location inside said support casing; an electric drive means housed inside said support casing for selectively rotating said drive members to axially move said rod members, thereby to pivotally adjust said mirror unit about said spherical mounting member, and thereby to adjust the angular position of said mirror unit with respect to said horizontal and vertical axes; each said fixture portion and the respective said socket having complementary engaging surface means for preventing relative movement therebetween in any direction during axial movement of the respective said rod member and the resultant pivotal movement of said mirror unit; and each said neck portion having a diameter smaller than that of the respective said stem portion and an elastic flexibility greater than the elastic flexibility of said stem portion and sufficient to enable said neck portion to bend with respect to the axis of said stem portion upon said pivotal movement of said mirror unit.
Claim 2
Dependent Claim
346 words
An electric remote control rearview mirror assembly comprising: a mirror unit including a mirror support plate and a mirror having a reflective surface and a backside and supported by the mirror support plate with the backside facing thereto; a support casing positioned on one side of the mirror support plate remote from the mirror; a spherical mounting member positioned between the mirror unit and the support casing for clamping the mirror support plate thereon for pivotal movement around horizontal and vertical axes; a pair of sockets defined in the mirror support plate in spaced relation to the spherical mounting member and spaced a predetermined angle from each other with respect to the spherical mounting member; a pair of elastic rod members formed of elastic material, each said elastic rod member comprising a stem portion, an end fixture portion fitted in a respective said socket, and a neck portion between said stem portion and said fixture portion; a pair of drive members formed of rigid material and rotatably supported inside said support casing, each said drive member being held in driving engagement with said stem portion of a respective said rod member at a location inside said support casing; an electric drive means housed inside said support casing for selectively rotating said drive members to axially move said rod members, thereby to pivotally adjust said mirror unit about said spherical mounting member, and thereby to adjust the angular position of said mirror unit with respect to said horizontal and vertical axes; each said fixture portion and the respective said socket having complementary engaging surface means for preventing relative movement therebetween in any direction during axial movement of the respective said rod member and the resultant pivotal movement of said mirror unit; and each said neck portion having a diameter smaller than that of the respective said stem portion and an elastic flexibility greater than the elastic flexibility of said stem portion and sufficient to enable said neck portion to bend with respect to the axis of said stem portion upon said pivotal movement of said mirror unit.
Claim 3
Dependent Claim
32 words
A mirror assembly as claimed in claim 1, wherein each of said drive members comprises a ring member having a central bore receiving said stem portion of the respective said rod member.
Claim 4
Dependent Claim
47 words
A mirror assembly as claimed in claim 2, wherein each of said ring members has internal threads defined on the inner peripheral face thereof, said internal threads in each of said ring members being elastically threadingly engaged with said stem portion of the respective said rod member.
Claim 5
Dependent Claim
52 words
A mirror assembly as claimed in claim 2, wherein each of said ring members has internal threads defined on the inner peripheral face thereof, said internal threads of each of said ring members being threadingly engaged with external threads on the exterior of said stem portion of the respective said rod member.
Claim 6
Dependent Claim
51 words
A mirror assembly as claimed in claim 1, wherein each of said drive members comprises a pair of pinch rollers positioned one on each side of said stem portion of the respective said rod member, one of said pinch rollers being adapted to receive the drive from said electric drive means.
Claim 7
Dependent Claim
72 words
A mirror assembly as claimed in claim 1, wherein said support casing has bearing apertures defined therein, said rod members extending from said mirror support plate into said support casing through the respective said bearing apertures, and further comprising an elastic sealing ring interposed between said support casing and one of said drive members in alignment with the respective said bearing aperature and also in alignment with the respective said rod member.
