Abstract: A bleacher seating system provides a seatback locking and release mechanism that allows for rapid simultaneous repositioning of the seat back portions in each row of seating to aid in setting up and collapsing sets of seating rows. The locking and release mechanism may be actuated to substantially simultaneously unlock all seat back portions in a row from a single location. The bleacher seating system may be readily set up or collapsed by a single operator, such as by manually or remotely unlocking and locking the seat back portions in rows so that the seat backs may be pivoted between raised and lowered positions. In addition, deck nosemount clamps allow for increased walking space behind the seats and a particularly compact seating storage configuration.

The frame may incorporate asymmetry in its layout, in the size or presence of frame members, or in the positioning of the nodes.

Abstract: An actuator opens and closes a lid on a bulk storage container. The actuator may be activated remotely using a remote control. When actuated, the actuator will lift the lid so that it is clear of the structure, and will then rotate the lid in a horizontal plan about a vertical axis until the lid is rotated to uncover the opening. The axis of rotation is located near the perimeter of the opening, so that very little of the lid remains over the opening when in the open position. To close the lid from the open position, the remote control may then again be used to actuate the closing process. The closing process works in reverse of the opening process. Therefore, during closing, the lid will rotate back to its original orientation over the hole and then lower into the closed position.
