Low-profile lens mount
Disclosed is a housing for a portable handheld electronic device such as a cellphone. The device has a housing, having a left side and right side. At least one of the left side and right side is provided with integral surface features or surface structures to enhance gripping the cellphone, preferably along the entire length of the phone or within about the top half or one third of the phone.
1. An optical element lockable to and removable from an imaging device, the optical element comprising:
a first piece comprising a compression surface, a plurality of first flanges, and an aperture; and
a second piece coupled to the first piece via a threaded connection between the first piece and the second piece, the second piece comprising a corresponding compression surface, a plurality of second flanges, and an aperture, the first and second pieces arranged with respect to one another such that a central axis of the optical element extends through the apertures of both of the first and second pieces;
wherein the threaded connection is configured such that rotation of the second piece about the central axis rotates each flange of the plurality of second flanges underneath a corresponding flange of the plurality of first flanges and reduces a spacing between the compression surface of the first piece and the corresponding compression surface of the second piece; and
wherein a first interface of the optical element comprising the first piece and the second piece forms a first side of a positive lock mounting system configured to mate with a second side of the positive lock mounting system provided on an imaging device.
2. An optical element as in claim 1 , wherein prior to the rotation of the second piece, the spacing between the compression surface of the first piece and the corresponding compression surface of the second piece is dimensioned to accommodate a projection of a mount support provided on the imaging device.
3. An optical element as in claim 1 , wherein the first piece is positioned along the central axis between first and second portions of the second piece.
4. An optical element as in claim 3 , wherein the second portion of the second piece comprises an annular periphery arranged to be accessible for rotation by a user when the first portion of the second piece is inserted into an aperture of a mount support provided on the imaging device.
5. A optical element as in claim 1 , wherein the optical element is configured to mate with a mount support of a phone.
6. A optical element as in claim 1 , wherein the optical element is a camera lens.
7. An optical element as in claim 1 , wherein the optical element is a lens mount adapter configured to allow for removable attachment of a camera lens thereto.
8. An optical element as in claim 7 , wherein the optical element is configured to fasten to a support on a housing of the imaging device, forming an effective flange focal distance of no more than about 25 millimeters.
9. An optical element as in claim 7 , wherein the optical element is configured to fasten to a support on a housing of the imaging device, forming an effective flange focal distance of no more than about 20 millimeters.
10. An optical element as in claim 1 , wherein the plurality of second flanges comprises at least two rotatable projections on the second piece arranged on a periphery of the second piece.
11. An optical element as in claim 10 , wherein the at least two rotatable projections on the second piece comprise six rotatable projections on the second piece.
12. An optical element as in claim 10 , wherein the plurality of first flanges comprises at least two projections on the first piece arranged on a periphery of the first piece.
13. An optical element as in claim 12 , wherein the at least two projections on the first piece comprise six projections on the first piece.
14. An optical element as in claim 1 , wherein the plurality of second flanges on the second piece are movable between a first position in which they are rotationally aligned with the plurality of first flanges on the first piece, and a second position in which they are rotationally offset from the plurality of first flanges on the first piece.
15. An optical element lockable to and removable from an imaging device, the optical element comprising:
a first piece comprising a compression surface and an aperture;
a second piece coupled to the first piece via a threaded connection between the first piece and the second piece, the second piece comprising a corresponding compression surface and an aperture, the first and second pieces arranged with respect to one another such that a central axis of the optical element extends through the apertures of both of the first and second pieces; and
a lens flange surface normal to the central axis, a post movably mounted with respect to the lens flange surface, and a button coupled to the second piece;
wherein the threaded connection is configured such that rotation of the second piece about the central axis reduces a spacing between the compression surface of the first piece and the corresponding compression surface of the second piece, wherein the button engages the post when the second piece is rotated to a first position, such that user actuation of the button causes movement of the post from an extended position to a retracted position with respect to the lens flange surface, wherein the button is displaced from the post when the second piece is rotated away from the first position; and wherein the optical element is a lens mount adapter configured to allow for removable attachment of a camera lens thereto.
