Abstract
A foot actuated pivoting lever is provided. The lever may include: a lever member having two ends, one end configured to attach to a mechanism configured to receive an input from the lever member; and a pedal pivotally attached proximate to the other end of the lever member, wherein the pedal is configured to pivot between a first and a second position, wherein in the first position, the pedal lies on top of a section of the lever member and, in the second position, the pedal extends beyond the lever member. A mechanism for actuating a piston may be provided.
Claims18
A foot actuated pivoting lever comprising:
- a lever member having two ends, one end configured to attach to a mechanism configured to receive an input from the lever member;
- and
- a pedal pivotally attached proximate to the other end of the lever member, wherein the pedal is configured to pivot between a first and a second position,
- wherein in the first position, the pedal lies on top of a section of the lever member, and in the second position, the pedal extends beyond the lever member.
A mechanism for actuating a piston comprising:
- an input lever;
- an input bracket attached to the lever;
- a fixed bracket pivotally connected to the input bracket;
- a connecting link pivotally connected to the fixed bracket;
- a rocker link pivotally connected to the connecting link and also pivotally connected to the input bracket;
- and
- a pusher attached to the rocker link and configured to push on the piston when the rocker rotates.
A method of actuating a cylinder comprising:
- configuring a foot pedal to move an input lever;
- connecting an input bracket attached to the lever;
- fixing a bracket;
- pivotally connecting the fixed bracket to the input bracket;
- connecting a connecting link pivotally to the fixed bracket;
- connecting a rocker link;
- pivotally connecting the rocker link to the connecting link;
- pivotally connecting the rocker link to the input bracket;
- providing a pusher attached to the rocker link;
- and
- configuring the pusher link to push on the piston when the rocker rotates in a particular direction.
A foot actuated pivoting lever comprising:
- a lever member having two ends, one end configured to attach to a mechanism configured to receive an input from the lever member;
- and
- means for extending a lever arm of the lever member pivotally attached proximate to the second end of the lever member, wherein the extending means is configured to pivot between a first and a second position,
- wherein in the first position, the extending means lies on top of a section of the lever member and in the second position the extending means extends beyond the lever member.
A mechanism for actuating a piston comprising:
- means for inputting a force into the mechanism;
- an input bracket attached to the inputting means;
- a fixed bracket pivotally connected to the input bracket;
- a connecting link pivotally connected to the fixed bracket;
- a rocker link pivotally connected to the connecting link and also pivotally connected to the input bracket;
- and
- a pusher attached to the rocker link and configured to push on the piston when the rocker rotates.
