Patent attributes
A button assembly includes a top assembly, an attachment body, and a resilient member. The top assembly includes a cap and a locking ring defining a receiving area, and the locking ring includes a top protrusion extending into the receiving area. The attachment body includes a locking feature that includes a body protrusion and a notched portion. The resilient member is located between the cap and the attachment body such that the cap is movable toward the attachment body. In some examples, the top assembly is selectively engageable with the attachment body by aligning the top protrusion of the locking ring with the notched portion of the locking feature, pushing the top assembly toward the attachment body, and rotating the top assembly relative to the attachment body such that the top protrusion of the locking ring is aligned with the body protrusion of the locking feature.
