Abstract

An extendable mirror assembly configured to be coupled to a vehicle includes a drive assembly, a mirror moveable between a retracted position and an extended position, and a support arm including a first end opposite a second end. The second end of the support arm is coupled to the mirror and a flange is coupled to the first end of the support arm. A support body is coupled to the support arm by the flange and is configured to translate along an axis in response to actuation of the drive assembly to move the mirror between the retracted position and the extended position.

First claim

The invention claimed is:

1. An extendable mirror assembly configured to be coupled to a vehicle, the extendable mirror assembly comprising:
a drive assembly;
a mirror moveable between a retracted position and an extended position;
a support arm including a first end opposite a second end, the second end of the support arm coupled to the mirror;
a flange coupled to the first end of the support arm; and
a support body coupled to the support arm by the flange, the support body configured to translate along an axis in response to actuation of the drive assembly to move the mirror between the retracted position and the extended position, wherein the flange is secured to the support body by fasteners extending parallel to the axis.

2. The extendable mirror assembly of claim 1 , wherein the flange presents a first contact surface facing away from the mirror in a first direction along the axis, and wherein the support body presents a second surface facing toward the mirror in a second direction along the axis.

3. The extendable mirror assembly of claim 2 , wherein the first and second surfaces each define a plane perpendicular to the axis.

4. The extendable mirror assembly of claim 1 , wherein the flange is welded to the support arm.

5. The extendable mirror assembly of claim 1 , wherein the flange is in the form of a plate member extending from the support arm radially from the axis.

6. The extendable mirror assembly of claim 1 , wherein the flange is configured for coupling to the support body at four spaced-apart fastening points.

7. The extendable mirror assembly of claim 1 , wherein the support body includes a plurality of apertures oriented parallel to the axis, and wherein the flange includes a plurality of apertures, each of which aligns with one of the plurality of apertures of the support body, and wherein each of the plurality of apertures of the support body and the flange receives one of the fasteners.

8. A vehicle comprising:
a cab for supporting an operator of the vehicle; and
an extendable mirror assembly including
a mirror base coupled to the vehicle adjacent the cab,
a drive assembly coupled to the mirror base and operable to move a mirror between a retracted position and an extended position,
a support arm including a first end and a second end, the second end coupled to the mirror,
a fastening interface member fixedly attached to the first end of the support arm, and
a support body coupled to the support arm by the fastening interface member, the support body cooperatively engaged with the drive assembly to move along an axis defined by the drive assembly for movement of the mirror between the retracted position and the extended position, wherein the fastening interface member is secured to the support body by fasteners extending parallel to the axis.

9. The vehicle of claim 8 , wherein the fastening interface member includes a first surface facing away from the mirror in a first direction along the axis, and wherein the support body includes a second surface facing toward the mirror in a second direction along the axis, and wherein the surfaces of the fastening interface member and the support body abut during operation of the drive assembly.

10. The vehicle of claim 8 , wherein the fastening interface member includes a first surface defining a first plane coincident therewith, and wherein the support body includes a second surface defining a second plane coincident therewith, and wherein the first and second planes are perpendicular to the axis.

11. The vehicle of claim 8 , wherein the fastening interface member is a plate member extending radially with respect to the axis.

12. An extendable mirror assembly configured to be coupled to a vehicle, the extendable mirror assembly comprising:
a drive assembly;
a mirror moveable between a retracted position and an extended position;
a support arm including a first end opposite a second end, the second end of the support arm coupled to the mirror;
a fastening interface member coupled to the first end of the support arm; and
a support body coupled to the support arm by the fastening interface member, the support body configured to translate along an axis in response to actuation of the drive assembly to move the mirror between the retracted position and the extended position, wherein the support body includes a plurality of apertures oriented parallel to the axis, and wherein the fastening interface member includes a plurality of apertures, each of which aligns with one of the plurality of apertures of the support body during operation of the drive assembly.
