Adjustable fixture mechanism

An adjustable fixture mechanism comprising:

• a first housing having an adjustment aperture;
• an adjustment control plate supported by the first housing, the adjustment control plate having an adjustment control aperture;
• an adjustment member disposed within the adjustment aperture, the adjustment member including a proximal end, a distal end and a first central axis extending through the proximal and distal ends;
• an adjustment control member disposed within the adjustment control aperture, the adjustment control member including a proximal end and a distal end and rotatable within the adjustment control aperture about a second central axis that is offset from the first central axis, the distal end of the adjustment control member including a ramped surface extending about the second central axis, the ramped surface contacting the proximal end of the adjustment member;
• and
• a second housing, a supporting body, and a biasing member, the supporting body disposed between the first and second housing, the biasing member having a first end and a second end, the first end engaging the supporting body, the second end engaging the distal end of the adjustment control member.

An adjustable fixture mechanism comprising:

• a housing having an adjustment aperture;
• an adjustment control plate coupled to the housing, the adjustment control plate having an adjustment control aperture;
• an adjustment member disposed within the adjustment aperture, the adjustment member including a proximal end and a distal end;
• and
• an adjustment control member disposed within the adjustment control aperture, the adjustment control member including a proximal end and a distal end, the distal end including a ramped helical surface, wherein the adjustment control member is eccentrically aligned with the adjustment member, such that the ramped helical surface engages the proximal end of the adjustment member,
• wherein the adjustment control member includes an annular lip and the adjustment control aperture includes an annular shoulder for engaging the annular lip to secure the adjustment control member within the adjustment control aperture, the adjustable fixture mechanism further comprising a biasing member operable to bias the annular lip into engagement with the annular shoulder.
