Apparatus for retaining a ball joint, and an assembly and a method thereof

摘要

An assembly for enabling multi-adjustment of a lamp is provided. The assembly includes a frame to which the lamp is attachable, a ball joint, and an apparatus for retaining the ball joint. The ball joint has a head and a neck. The apparatus is attached to the frame, and includes a housing and a cap. The housing defines a chamber configured to receive the head of the ball joint. The housing may further define a slot in which the neck is slidable such that the ball joint is insertable into and removable from the chamber. The cap is configured to interlock with the housing to secure the ball joint such that they are substantially restricted to rotational movement with respect to each other. The cap and the housing may have retention tabs and retention ridges, respectively, configured to engage with each other to enable the interlocking.
