US Patent 10421573 Linen hamper

A linen hamper made of a light weight tubular frame for releasably securing a hamper bag includes an open top which can be closed by a pivotally mounted lid. The lid is connected to a foot pedal pivotally mounted on the frame, by an adjustable control rod pivotally connected to each. A closing cylinder is biased to close the lid when pressure is removed from the foot pedal. However, the control rod is adjustable to a second state in which the pivot point of its connection to the lid is aligned or is over center relative to the pivot point of the lid, and with respect to the closing force exerted by the control rod on the lid, such that the closing cylinder cannot close the lid until the lid is tapped forwardly slightly.
