Quick coupler lock system

A coupler lock apparatus for use with heavy equipment, the coupler lock apparatus comprising:

• a coupler frame, including a pin grabber, the pin grabber for receiving and holding a pin;
• a coupler hook rotatable to engage the pin, the coupler hook pivotably attached to the coupler frame at a coupler hook pivot, and the coupler hook rotatable about the coupler hook pivot by action of a coupler actuator;
• a lock lever, the lock lever rotatable about a lock lever pivot, the lock lever including a lock lever arm, the lock lever arm positioned opposite a lever actuator pivot in relation to the lock lever pivot;
• a lock bar including a bar pivot, an engage surface, and a lock bar arm, the lock bar hingably attached to the coupler hook at the bar pivot;
• and
• the lock lever rotatable to contact the engage surface of the lock lever arm, to stop movement of the lock bar.

A coupler lock apparatus for use with heavy equipment, the coupler lock apparatus including:

• a coupler frame, the coupler frame including a pin grabber, the pin grabber for receiving and holding the pin in an engaged position;
• a coupler hook rotatable to engage the pin, the coupler hook pivotably attached to the coupler frame at a coupler hook pivot;
• a lock lever, the lock lever rotatable about a lock lever pivot;
• a coupler actuator pivotably attached to the coupler hook at a hook actuator pivot, the coupler actuator piviotably attached to the lock lever at a lever actuator pivot, and an actuation of the coupler actuator pivotably cranks the lock lever about the lock lever pivot;
• a lock bar including a bar pivot and an lock bar engage surface, the lock bar hingably attached to the coupler hook at the bar pivot, the lock bar rotatable with the coupler hook as the actuation of the coupler actuator cranks the coupler hook about the coupler hook pivot;
• and
• the lock lever arm contactable to the lock bar engage surface, to prevent movement of the coupler hook out of the engaged position to release the pin.

A coupler lock apparatus for use with heavy equipment, the coupler lock apparatus including:

• a coupler frame, the coupler frame including a front pin grabber and a rear pin grabber, the front pin grabber for receiving and holding the front pin in an engaged position, and the rear pin grabber receives and holds a rear pin, of a set of pins;
• a coupler hook rotatable to engage the front pin, the coupler hook pivotably attached to the coupler frame at a coupler hook pivot;
• a lock lever, the lock lever rotatable about a lock lever pivot;
• a coupler actuator pivotably attached to the coupler hook at a hook actuator pivot, the coupler actuator piviotably attached to the lock lever at a lever actuator pivot, and an actuation of the coupler actuator pivotably cranks the lock lever about the lock lever pivot;
• a lock bar including a bar pivot, a lock bar arm, and an lock bar engage surface, the lock bar arm opposed to the bar pivot about the lock lever pivot, the lock bar arm extendable through a lock bar collar, the lock bar hingably attached to the coupler hook at the bar pivot, the lock bar rotatable with the coupler hook as the actuation of the coupler actuator cranks the coupler hook about the coupler hook pivot, and the bar pivot co-located with the hook actuator pivot on the coupler hook;
• and
• the lock lever arm contactable to the lock bar engage surface, to prevent movement of the coupler hook out of the engaged position to release the front pin.
