Abstract:
A gatebox for an aircraft comprises a hopper configured to contain a solid material or a liquid material in the gatebox, an opening within the hopper configured to allow a solid material in the hopper to be discharged from the gatebox, and a door mechanism with a door that is configured to operate in a first mode to release the solid material from the opening and a second mode to prevent the liquid material from escaping through the opening, wherein the door mechanism is configured to move the door linearly when operating in the first mode.
Abstract:
The present disclosure relates a gearbox for power lift gate including a rotating frame (22/22′) arranged in the housing and rotatable relative to the housing, a sun roller (23) and a plurality of planetary gears (24) supported by the rotating frame (22/22′), an inner ring tooth (218) provided in the housing, and the planetary gear (24) being surrounded around the sun roller (23) in the central area. The sun roller (23) includes a first rod (230) with helical teeth which is meshed with a first gear (240) of the planetary gear, and a second rod (232) extending coaxially from the first rod (230). The planetary gear includes a second gear (242) meshed with the inner ring gear (218) of the housing to drive the rotating frame to rotate and revolve synchronously for driving external loads.
Abstract:
The assembly includes a pulley, a plastic rail and a bolt for fixing the pulley to the plastic rail in an axial direction but allowing the pulley to rotate around the bolt. The bolt includes a threaded shaft, a shank, a shoulder, an annular groove, and a head. The assembly further includes a metal sheet with a central hole, such that when inserting the metal sheet through the threaded shaft, which has been previously introduced in a through hole of the plastic rail, the metal sheet contacts partially with a shoulder support base and partially with the plastic rail, such that when the metal sheet is axially compressed against the support base, the hole diameter of the metal sheet becomes smaller than that of the threaded shaft and gets in the annular groove.
Abstract:
A door closer, comprising a door closer housing mounted to one of a door frame or a door surface and a linkage arm for pivoting the door between open and closed positions. The linkage arm has a first and second end, the first end mounted to the other of the door frame or the door surface. The door closer includes a rotatable connector between the linkage arm and the door closer housing, the linkage arm second end engaging with the rotatable connector. The connector has a rotatable body portion and head protrusion substantially secured in a female receptor to transmit rotation about a longitudinal axis of the connector. One or both of the head protrusion or female receptor has a curved profile and is further movable with respect to the head protrusion to permit limited rotational misalignment of the linkage arm on any axis perpendicular to the connector longitudinal axis.
Abstract:
This top hung door assembly (10) for a merchandiser includes a pair of doors 12, 14 each having an upper frame member (20) including a metal reinforcing member (22). An upper track member (16) is provided including depending flange members (36) and (38) each having a roller mounting portion (48). A pair of spaced wheel assemblies (60) is provided including a bracket (50) having a lower portion (54) connected to the upper door frame and an upper portion (52) carrying a pair of rollers (60) received by the roller mounting portion (46). The upper track member (16) includes associate track members (46) having spaced notches (49) to facilitate mounting the doors. Also the flange members have flexible tips (44) facilitating the sealing and mounting of the doors.
