A balanced lid type system for industrial trash bins includes arrangements for partially opening the lid with little effort and for permitting the lid to swing wide open when it is inverted for dumping, as disclosed in U.S. Pat. Nos. 3,994,415 and Re. 29,494. The operative mechanism in the present balanced lid bin system includes rollers which ride on the top edge of the sides of the bin to support the lid in a substantially balanced manner, and a pair of recesses or guideways in the rear sides of the lid which engage matching pins or rollers extending laterally from the bin to guide the lid as it rotates open in the upright or balanced partially opening mode of operation. When the lid swings wide open, as it is inverted when raised by the forks of a lift garbage dump truck, the rollers remain at the end of the tracks in the lid and the lid swings fully open about this axis. In the wide-open position, the tracks of the lid make a substantial angle with the vertical, so that vibration of the bin to assure complete emptying of it, will not jam or damage the tracks or mating roller assemblies.

A commercial trash bin and lid system comprising: a large generally rectangular commercial trash bin; means secured to said bin to facilitate raising said bin and turning it upside down to dump it; a lid for said bin; means for supporting said lid near its balancing point to permit easy opening of said lid; means for guiding and restraining the rear of said lid as it is opened, said means including a pair of pins or rollers extending laterally from the top rear of the sides of said bin, and a pair of guideways secured to the rear sides of said lid, for guiding the position of the rear of said lid as it is partially opened using said supporting means while said bin is in the upright orientation; means for stopping the movement of said lid in a partially open position when it is opened in the upright orientation; 1 said guideways extending generally upward from said pins when said lid is closed; means for permitting said lid to swing wide open with said lid pivoting about said pins or rollers in one end of said guideways and with said supporting means inoperative, when said bin is turned upside down for dumping, with each said guideway extending to the rear from the pivot point, whereby vertical vibration of said bin to dislodge trash when said bin is in the upside-down orientation will not jam or damage said pins or guideways.
