Abstract
Rotatable handles and related methods are disclosed herein. In one form, the handle has a first clamp member, a second clamp member connected to the first clamp member on one end and mating with the first clamp member at another end, and an actuator operable to drive the mated ends of the first clamp member and second clamp member together to create a clamping force between the first clamp member and the second clamp member and secure the rotatable handle into a fixed position with respect to an object to which the rotatable handle is connected. Various methods are also disclosed herein with respect to the rotatable handle.
Claims9
A rotatable handle comprising:
- a pivotably mounted first clamp member;
- a second clamp member connected to the first clamp member on a first end and mating with the first clamp member at a second end;
- a rotatable grip extending radially from the first and second clamp members along a longitudinal axis;
- and
- a locking structure comprising a locking cam on the rotatable grip, a locking recess on the first clamp member, and a locking protrusion on the second clamp member;
- wherein rotation of the rotatable grip about the longitudinal axis causes the locking cam to contact the locking protrusion and push the locking protrusion in a direction substantially perpendicular to the longitudinal axis into the locking recess in order to close a gap between the second end of the first and second clamp members and create a clamping force.
A rotatable handle comprising:
- a pivotable first ring portion having a first end and a second end;
- a second ring portion having a third end and a fourth end, the third end being connected to the first end of the first ring portion;
- a rotatable grip extending radially from the first and second ring portions along a longitudinal axis;
- and
- a locking structure comprising a locking cam on the rotatable grip, a locking recess on the first ring portion, and a locking protrusion on the second ring portion;
- wherein rotation of the rotatable grip about the longitudinal axis causes the locking cam to contact the locking protrusion and push the locking protrusion in a direction substantially perpendicular to the longitudinal axis into the locking recess in order to close a gap between the second end of the first ring portion and fourth end of the second ring portion and create a clamping force.
A rotatable handle assembly comprising:
- a pivotable first clamp member;
- a second clamp member connected to the first clamp member on a first end and mating with the first clamp member at a second end;
- a fractional turn handle extending radially from the first and second clamp members along a longitudinal axis and movable between a first handle position wherein the first clamp member is in a secured position and a second handle position wherein the first clamp member is in an unsecured position;
- and
- a locking structure comprising a locking cam on the fractional turn handle, a locking recess on the first clamp member, and a locking protrusion on the second clamp member;
- wherein the fractional turn handle is movable from the first handle position to the second handle position by rotating the fractional turn handle about the longitudinal axis thereof by less than 180°, and wherein the first clamp member is moved between the secured position and the unsecured position by the rotation of the fractional turn handle;
- wherein rotation of the fractional turn handle about the longitudinal axis from the second handle position to the first handle position causes the locking cam to contact the locking protrusion and push the locking protrusion in a direction substantially perpendicular to the longitudinal axis into the locking recess in order to close a gap between the second end of the first and second clamp members and create a clamping force.
