A swivel mechanism for a rotating cantilever post including a cantilever boom and a post, the swivel mechanism comprising at least one first gear associated with the cantilever boom and at least one second gear rotatably mounted to the post, wherein the at least one second gear is operatively associated with the at least one first gear such that rotation of the at least one second gear causes rotation of the at least one first gear, rotating the cantilever boom relative to the post.

The present disclosure relates to the technical field of decorative lamps, and provides an articulated device and a foldable star lamp including the same. The articulated device includes an articulated joint and an articulated base, wherein the articulated joint includes an articulated joint bottom and an articulated joint top, the articulated joint bottom is sleeved on the articulated base and is capable of pivoting around a fixed axle, the articulated base is provided with a first stop block for preventing excessive rotation of the articulated joint.

A tool is provided for stabilizing a position of a shaft disposed within a casing and rotatably supported by a pair of bearings that are spaced-apart from one another and located within the casing. The tool includes an arcuately-shaped shoe that is located between the pair of bearings and releasably connected to the casing. The shoe has a concave surface defining a radius corresponding to a radius of the shaft. The shoe is resiliently biased away from the casing for facilitating the concave surface of the shoe to radially abut with a portion of an outer circumference of the shaft.

A ball socket for connection with a ball stud resists accidental pull-out of the ball stud. The ball socket achieves relatively low insertion force but relatively high pull-out force resistance.

A light source apparatus (100) includes: a chamber (101) having a chamber wall (103) defining an opening (107); and a support apparatus (110) including a support device (111) positioned within the opening of the chamber wall. The support device includes: a cup (112) having an inner surface (114) configured to retain a movable apparatus and an outer surface (116) having a first outer diameter; and a plurality of rods (118) arranged at the outer surface of the cup such that the arrangement of the plurality of rods defines a second outer diameter, the second outer diameter greater than the first outer diameter. The chamber wall is configured to hold the support device such that the chamber wall contacts the plurality of rods when the support device is positioned within the opening of the chamber wall, and the outer surface of the cup does not contact the chamber wall.

A ball socket for connection with a ball stud resists accidental pull-out of the ball stud. The ball socket achieves relatively low insertion force but relatively high pull-out force resistance.

A bearing assembly includes a shaft and a thrust runner attached to the shaft. The shaft runner protrudes radially outward from the shaft. A thrust bearing is positioned axially adjacent to the thrust runner. A first flow passage is between the thrust runner and a first face of the thrust bearing. A second flow passage is between a second face of the thrust bearing and a housing. A restriction feature restricts a flow of fluid through the second flow passage.

Example embodiments relate to tiltable luminaire joints. One example tiltable joint for a luminaire includes a first joint portion that includes a joint member provided with an outer cylindrical surface section having an axis and opposing bearings aligned with said axis. The outer cylindrical surface section being provided with a first plurality of interengaging surfaces. The tiltable joint also includes a second joint portion that includes a joint housing provided with a pair of axially-aligned receiving surfaces, and an inner cylindrical surface provided with a second plurality of interengaging surfaces configured to interengage the first plurality of interengaging surface. The joint member of the first joint portion is configured for being housed within the joint housing of the second joint portion. Further, the tiltable joint includes first and second shaft portions that extend in alignment with the pair of axially-aligned bearings. Additionally, the tiltable joint includes a fixation means.
