An assist apparatus utilized within a door system to aid in opening the door. The assist apparatus may include one or more door activation devices (e.g., a first door activation device and a second door activation device, such as pulls on opposite sides of a sliding door) that can rotate around a pivot location. Moreover, the assist apparatus may further include one or more assist components operatively coupled to the one or more door activation devices. The door activation device(s) are configured to be operatively coupled to a sliding door and allow for rotation of at least a portion of the door activation device. The assist component(s) of the door activation device(s) aid in opening or closing the sliding door by engaging a door frame, wall, or the like as the door activation device is rotated.

A mechanism for precisely controlling a slide gate to provide certain and secure location of a sliding gate in a path of flowable dry bulk material, the mechanism including a rack and pinon gear with a shaft with a diameter hole therethrough for receiving a pin therethrough when the sliding gate is in a desired position. The swing arm is configured to inhibit removal of the pin and thereby prevent unwanted movement of the gate from the desired position. The swing arm is configured for selectively prohibiting accidental and/or intentional but unauthorized removal of the pin depending upon types of objects being placed through the open hole in the swing arm and the first fixed arm open hole.

Hardware for a lift glide door assembly and lift glide window assembly provides ease of opening with an operational opening assist that urges the door or window to an open position on operation of an opening handle. A lock mechanism actuates a lock pin, blocks opening gear mechanisms from operating and extends a security bolt for locking. A guide blade is provided for assisting the door during opening or closing operations.

A window operator for repositioning a window sash within a window frame. The window operator includes a crank handle for rotating a shaft with a pinion gear. The pinion gear operably engages with a rack containing cutouts, the rack having oppositely disposed first and second ends. The rack is translatable within a track disposed within the window frame. The window operator also includes an operator arm connectable between a first end of the rack and the sash wherein rotation of the shaft by the handle imparts movement to the rack and the operator arm, the rack and operator arm movement capable of transitioning the sash between a window open and a window closed position.

The present invention is a gear driven louver shutter system, wherein each louver of the shutter system is attached to the end of a pinion on at least one end. A plurality of teeth of each pinion is engaged with a gear track disposed within each frame member. When one louver is adjusted, all the louvers in the shutter system will move accordingly, due to the movement of the gear strip rotating the pinions in that frame member at the same rate.

A lid controlling apparatus includes a casing having a target region, a lid, and a rod driving mechanism connected between the casing and the lid. The rod driving mechanism includes a first rod pivoted to the casing, a non-rotatable gear fixed to the casing, a driven gear pivoted to a side of the first rod and connected to the lid, and a planetary gear device pivoted to the side of the first rod and engaged with the non-rotatable gear and the driven gear for rotating between lifting and closed positions. When the planetary gear device rotates to the lifting position, the first rod pivots with rotation of the planetary gear device to have a first included angle relative to the casing, and the planetary gear device rotates the driven gear to make the lid have a second included angle relative to the first rod for exposing the target region.
