System for converting rotation to displacement

A system for converting a rotational motion to a linear movement that comprises a rotational shaft, a power, source that is capable of rotating the rotational shaft, a targeted object, and an adjustable spinning arm that comprises a revolving piece and a rod;

• wherein the adjustable spinning arm is designed to convert a rotational motion of the shaft to a linear movement of the targeted object;
• wherein a lower end of the rod is connected to the shaft, and an upper end of the rod is axially connected to the revolving piece by a bearing;
• wherein the revolving piece is connected to the rod in a way that the revolving piece is in a state of tilting aside in relation to the rod such that a revolving axis line of the revolving piece crosses a rotation axis line of the rod;
• wherein the rotational shaft is designed to be connected to and to be rotated by the power source so that the rotational shaft can rotate the rod around its rotation axis;
• wherein the revolving piece is capable to move outwards and is designed to move outwards when the rod rotates so that the revolving piece can roll over and be in contact with the targeted object when the tilt of the revolving piece is from right to left with respect to a contact plane on the targeted object;
• wherein when the revolving piece rolls along and is in contact with the targeted object in a first direction the revolving piece can exert upward force on it so that the targeted object can move upward, and when the revolving piece rolls along and is in contact with the targeted object in a second direction the revolving piece can exert downward force on it so that the targeted object can move downward.

A system for converting a rotational motion to a linear movement, comprising:

• an inner rotational shaft,
• an outer rotational shaft,
• a power source that is capable to rotate said rotational shafts,
• a targeted object,
• a first inner adjustable spinning arm that comprises a first revolving piece, and a first rod that its lower end is connected to the inner rotational shaft and its upper end is axially connected by a first bearing to the first revolving piece;
• a second inner adjustable spinning arm that comprises a second revolving piece, and a second rod that its lower end is connected to the inner rotational shaft and its upper end is axially connected by a second bearing to the second revolving piece;
• a third outer adjustable spinning arm that comprises a third revolving piece, and a third rod that its lower end is connected to the outer rotational shaft and its upper end is axially connected by a third hinge bearing to the third revolving piece;
• a fourth outer adjustable spinning arm that comprises a fourth revolving piece, and a fourth rod that its lower end is connected to the outer rotational shaft and its upper end is axially connected by a fourth bearing to the fourth revolving piece;
• wherein said inner and outer adjustable spinning arms are designed to convert a rotational motion of the inner and outer shafts to a linear movement of the targeted object;
• wherein the first revolving piece is connected to the first rod in a way that the first revolving piece is in a state of tilting aside in relation to the first rod such that a first revolving axis line of the first revolving piece crosses a first rotation axis line of the first rod;
• wherein the second revolving piece is connected to the second rod in a way that the second revolving piece is in a state of tilting aside in relation to the second rod such that a second revolving axis line of the second revolving piece crosses a second rotation axis line of the second rod;
• wherein the third revolving piece is connected to the third rod in a way that the third revolving piece is in a state of tilting aside in relation to the third rod such that a third revolving axis line of the third revolving piece crosses a third rotation axis line of the third rod;
• wherein the fourth revolving piece is connected to the fourth rod in a way that the fourth revolving piece is in a state of tilting aside in relation to the fourth rod such that a fourth revolving axis line of the fourth revolving piece crosses a fourth rotation axis line of the fourth rod;
• wherein said rotational shafts are designed to be connected to and to be rotated by the power source so that the rotational shafts can rotate said rods around their rotation axis;
• wherein said revolving pieces are capable of moving outwards and are designed to roll over and be in contact with the targeted object when the tilts of said revolving pieces are from right to left with respect to a contact plane on the targeted object;
• wherein the power source is designed to rotate the inner rotational shaft to clockwise and at the same time to rotate the outer rotational shaft to counterclockwise;
• wherein when the first and second revolving pieces rolls over and in contact with the targeted object clockwise and the third and fourth revolving pieces rolls over clockwise and are in contact with the targeted object and the third and fourth revolving pieces rolls over counterclockwise and in contact with the targeted piece said revolving pieces can exert upward force on the targeted object so that the targeted object can move upward, and a clockwise horizontal force that the first and second revolving pieces can exert on the targeted object can be negated by a counterclockwise horizontal force that the third and fourth revolving pieces can exert on the targeted object.
