Pivot bin with lift assist assembly and method of use thereof

A method of pivoting an aircraft storage bin, wherein the aircraft storage bin includes a bucket that pivots with respect to an upper housing, the method comprising the steps of:

• (a) pivoting the bucket from a closed position to an intermediate position, wherein a lift assist unit extends between the bucket and the upper housing, wherein the lift assist unit includes a lift assist spring and a housing, wherein the lift assist spring extends between a first end of the lift assist unit and the housing,
• (b) placing weight in the bucket,
• (c) if the weight placed in the bucket exceeds a predetermined weight threshold the bucket moves to an open position, wherein at least one of the bucket or the upper housing includes a soft stop assembly having a trigger spring associated therewith, wherein the trigger spring is compressed to a predetermined level when the bucket is in the intermediate position and the weight in the bucket exceeds the predetermined weight threshold, wherein the soft stop assembly includes an abutment member operatively associated with the trigger spring, wherein the abutment member extends downwardly from the upper housing such that when the bucket is in the intermediate position the abutment member contacts the bucket or upwardly from the bucket such that when the bucket is in the intermediate position the abutment member contacts the upper housing, wherein the trigger spring is compressed axially when the bucket pivots to the open position, wherein movement of the bucket to the open position causes a ratcheting mechanism in the lift assist unit to activate, thereby releasing the housing to move and provide lift assist as a result of the force from the lift assist spring,
• (d) if the weight placed in the bucket does not exceed a predetermined weight threshold the bucket does not move to the open position and the ratcheting mechanism in the lift assist unit is not activated, and
• (e) pivoting the bucket to the closed position, wherein if the weight in the bucket exceeds the predetermined weight threshold, the lift assist unit provides assistance as the bucket is pivoting to the closed position, and wherein if the weight in the bucket does not exceed the predetermined weight threshold, the lift assist unit does not provide assistance as the bucket is pivoting to the closed position.

• placing weight that exceeds a predetermined weight threshold in the bucket, thereby causing the bucket to move to an open position, wherein the trigger spring is compressed to a predetermined level when the bucket is in the intermediate position and the weight in the bucket exceeds the predetermined weight threshold, wherein movement of the bucket to the open position causes a ratcheting mechanism in the lift assist unit to activate, thereby releasing the housing to move and provide lift assist as a result of the force from the lift assist spring, and
• pivoting the bucket from the open position to the closed position, wherein the lift assist unit provides assistance as the bucket is pivoting from the open position to the closed position.
