ABSTRACT:
A cover assembly includes a ring mounted on a garbage bin, a cover mounted on the ring and a slow pivot device for slowly pivoting the cover relative to the ring. The slow pivot device includes a slow pivot element installed between the ring and the cover. The slow pivot element includes an internal tube, an external tube enclosing the internal tube and a spring connected between the internal tube and the external tube. Thus, rotation of the internal tube relative to the external tube exerts a torque on the spring. The spring is received in the internal tube so that an end thereof is connected with the internal tube. The internal tube is received in the internal tube so that an end thereof is connected with the internal tube. The internal tube is received in the external tube so that the other end of the spring is connected with the external tube. The internal tube includes a clip formed on an internal side thereof for clipping an end of the spring. The external tube includes a clip formed on an internal side thereof for clipping an opposite end of the spring. Damping oil is provided between the internal tube and the external tube so as to camp pivot of the internal tube relative to the external tube.
