Abstract
A lockable lateral adjuster mechanism comprises a platform with a channel carried by a base. A cam has an eccentric head that is pivotally disposed in the channel. The cam has a stem extending through the channel and into a counter bore in the base. The platform is laterally displaceable with respect to the base as the cam pivots. A countersunk interface is disposed between the eccentric head and the channel. A fastener extends through the cam to the base, and secures the cam, and thus the platform, to the base, and applies an axial load on the countersunk interface along an axis of rotation of the cam.
Claims19
A lockable lateral adjuster mechanism, the mechanism comprising:
- a platform carried by a base with a channel in the platform opposite the base, and an aperture in the channel aligned with a counter bore in the base;
- a cam with an eccentric head and a stem, the eccentric head being pivotally disposed in the channel and the stem extending through the aperture in the channel and being pivotally disposed in the counter bore, the eccentric head being off-axis with respect to the stem and the platform being laterally displaceable with respect to the base as the cam pivots;
- a conical opening in an end of the stem of the cam, the stem of the cam being segmented axially to form tabs;
- and
- a countersunk interface between the eccentric head and the channel.
A lockable lateral adjuster mechanism, the mechanism comprising:
- a base with a counter bore;
- a platform carried by the base and having an exterior face opposite the base;
- a channel formed in the exterior face of the platform and having a bottom in the platform with an aperture aligned with the counter bore of the base;
- a cam having a head and a stem, the head being pivotally disposed in the channel and the stem extending through the aperture in the channel of the platform and being pivotally disposed in the counter bore of the base, the head of the cam being eccentric with respect to the stem;
- a conical opening in an end of the stem of the cam;
- the platform being laterally displaceable with respect to the base as the cam pivots;
- a countersunk interface between the head and the channel with an inner side of the eccentric head being frusto-conical, and the channel comprising an interior bevel;
- and
- a fastener extending through a bore in the cam to the base, and securing the cam, and thus the platform, to the base, and capable of applying an axial load on the countersunk interface along an axis of rotation of the cam.
A lockable lateral adjuster mechanism, the mechanism comprising:
- a base;
- a platform carried by the base and selectively and laterally displaceable with respect to the base, the platform having an exterior face opposite the base;
- a set of three spaced-apart adjustments between the base and the platform, each comprising:
- a counter bore in the base;
- a channel formed in the exterior face of the platform and having a bottom in the platform with an aperture aligned with the counter bore of the base;
- a cam having a head and a stem, the head being pivotally disposed in the channel and the stem extending through the aperture in the channel of the platform and being pivotally disposed in the counter bore of the base, the head of the cam being eccentric with respect to the stem;
- a conical opening in an end of the stem of the cam;
- the platform being displaceable with respect to the base as the cam pivots;
- a countersunk interface between the head and the channel;
- at least one cam of the three spaced-apart adjustments being pivotal to laterally displace the platform with respect to the base in a first linear direction;
- at least another cam of the three spaced-apart adjustments being pivotal to laterally displace the platform with respect to the base in a second linear direction, perpendicular to the first linear direction;
- and
- at least one cam of the three spaced-apart adjustments being pivotal to pivot the platform with respect to the base.
