Abstract
A method of driving a work body to an obtuse angle relative to a drive body by providing a pivotal mounting of a work body such that it can pivot up to 180 degrees, mounting a drive body at a spaced position above the pivotal mount of the work body, pivotally mounting a first end of an elongated lever arm and pivotally mounting the distal second end to the operative end of the linear actuator and providing a drive arm from the work body to a leverage position on the lever arm between the first and second end. Also, the drive arm is pivotally mounted by the drive arm mount to the lower drive body and a sliding pivot slot pin is received in the linear slot extending along a portion of the drive arm to define a direction and limitation of movement of the drive arm relative to the lever arm.

A marine driver system for driving a work body pivotally connected to a drive body, the driver system including:
- a. a drive body substantially extending in a linear direction forming a reference axis;
- b. a work body pivoted at one end to the drive body at a pivot connection at or near the reference axis;
- c. a linear actuator having first and second opposing ends and mounted at the first opposing end to the work body at a position spaced to the pivot connection of the work body to the drive body;
- d. a lever arm having first and second pivot points at respective distal ends of the lever arm, the lever arm pivotally mounted at the first pivot point to the drive body and pivotally mounted at the second pivot point to the second opposing end of the linear actuator;
- and
- e. a drive arm pivotally mounted at one end on the lever arm and pivotally connected at the other end of the drive arm to the work body;
- wherein drive or retraction of the linear actuator provides a levered drive of the drive arm and driving or retracting of the pivotally connected work body,
- wherein the work body is a fan anchor,
- wherein the fan anchor includes an openable rigid frame fan anchor, and
- wherein in a first part of a driven rotation by the linear actuator, the openable rigid frame fan anchor rotates from an upright closed storage position and, in a second part of the driven rotation by the linear actuator, the openable rigid frame fan anchor further rotates toward an open fan anchor position.
A method of driving a work body through a pivoting angle relative to a drive body including the steps of:
- a. providing a pivotal mounting of a work body such that it can pivot up to 180 degrees;
- b. mounting a drive body at a spaced position above the pivotal mounting of the work body;
- c. pivotally mounting a first end of an elongated lever arm and pivotally mounting a second end to an operative end of a linear actuator;
- and
- d. providing a drive arm from the work body to a leverage position on the elongated lever arm between the first end and the second end,
- wherein the work body is drivably rotatable substantially 180 degrees or at least an obtuse angle relative to a reference axis to provide a working drive action and returnable to a substantially adjacent alignment when rotated back to a storage position,
- wherein the drive body provides a linear drive on the elongated lever arm to effect by an offset drive arm connection to the elongated lever arm and rotation of the work body to an operative position,
- wherein the drive arm is resiliently mounted to the elongated lever arm allowing limited relative movement wherein the resilient mounting allows limited bounce and return to the operative position, and
- wherein the work body is a spike anchor.
A spike anchor system having:
- a. a spike for driving into a waterbed when in use on a boat in shallow waters;
- b. a rotating work frame pivotally mounted at one end to a drive body substantially extending in a linear direction forming a reference axis, and wherein the spike is pivotally mounted to a second distal end of the drive body;
- c. a linear actuator mounted to the spike at a position spaced to a pivot connection of the rotating work frame to the drive body;
- d. a lever arm having first and second pivot points at distal ends, and pivotally mounted at the second pivot point to an end of the linear actuator;
- and
- e. a drive arm pivotally mounted on the lever arm in a position between the first and second pivot points to provide a levered drive of the drive arm by the linear actuator,
- wherein the spike can be drivably pivoted between a storage position out of the water and an operative position in the water, and wherein the rotating work frame includes a parallelogram drive frame.
