A hinge system for a storage bin in a cargo area of a vehicle includes a storage bin including a rod member, a nipper hook having an omega-shaped hook section surrounding the rod member, and a storage bin lid attached to lid connecting member of the nipper hook.

Slide operator assemblies and components for fenestration units, as well as associated methods of manufacture and use thereof.

An assistance apparatus for opening and closing a scissor door for a vehicle includes: a door hinge having one side installed at a vehicle body to be rotated vertically through a hinge shaft, and having a door mounted at an opposite side thereof; a gas lifter having a first side installed at the vehicle body, and having a second side installed at the door hinge to assist a rotational force of the door hinge or keep a posture thereof through compression and elongation; and an opening and closing assistance unit for providing the rotational force to the door hinge in interlocking with the pressing operation of a vehicle passenger.

A double sliding-plug door system includes a fixed frame, a sliding-plug rail arranged in the fixed frame, a cross beam, a driving mechanism, a linkage mechanism, a guide locking piece and a limiting mechanism. The driving mechanism has a screw rod and a motor driven nut assembly having a transmission frame, a nut sleeved in the screw rod and a follow-up member fixed in the nut; the nut mounted in the transmission frame, which itself is connected with an active sleeve assembly; the screw rod drives the nut assembly to reciprocate axially along the screw rod.

A sliding operator handle includes an actuatable brake providing at least one braking position in which the actuatable brake is configured to contact a track and restrict sliding motion of the track mount along the track and at least one sliding position in which the actuatable brake is configured to reduce contact with the track and allow sliding motion of the track mount along the track, and a handle pivotably coupled to the track mount. The handle is configured to receive a manual input force to slide the track mount in either direction along the track, and being further configured to actuate the actuatable brake in response to the manual input force. The handle includes a neutral position corresponding to the at least one braking position of the actuatable brake and actuation positions to allow sliding motion of the track mount along the track in response to manual input forces.

A gatebox system for delivering fire retardant fluid from a firefighting aircraft. A first and second gate opening are formed through a lower portion of a gatebox. The gates are hingedly connected along edges of the openings. A drive shaft in the gatebox is rotatable in gates-closing and gates-opening directions. Crank arms are fixed to the drive shaft and coupled to the gates by connecting links, which define an over-center geometry while the gates are at a closed position, such that weight of the fluid on the first gate induces torque on the drive shaft in the gates-closing direction. Rotation of the drive shaft in the gates-opening direction enables control of the fluid flow from the hopper according to an angular position of the drive shaft.

A casement window operator includes a linear input mechanism configured to be mounted to a stationary frame of a casement window, a linear to rotary motion converter operably coupled to an output of the linear input mechanism, a gear reducer operably coupled to an output of the rotary motion converter, and a sash arm operably coupled to an output of the gear reducer to rotate in conjunction with the output of the gear reducer. The sash arm is configured to extend from the stationary frame of the casement window to a rotatable window sash of the casement window.

According to particular embodiments, a door operating system comprises: a rotating handle removably coupled to a first gear; the first gear coupled to a second gear; the second gear removably coupled to a worm gear; and the worm gear coupled to a rotating plate. Rotation of the handle rotates the first gear which rotates the second gear which rotates the worm gear which rotates the rotating plate to cause the door to open or close. The first gear is swappable with the second gear to modify a gear ratio of the door operating system.
