Abstract:
A foldable stand comprising:a cylindrical tube unit having an inner wall surface defining an axially extending post-receiving chamber therein, and an outer wall surface; a post telescopically inserted into said post-receiving chamber so as to be movable relative to said tube unit in an axial direction, and having an upper post section extending outwardly from said post-receiving chamber; a locking device mounted on said tube unit for locking said post relative to said tube unit so as to expose a desired length of said upper post section outwardly from said post-receiving chamber; a positioning element fixed on said tube unit, and having an inner wall confronting and spaced apart from said outer wall surface of said tube unit to define a gap therebetween; and first, second and third support legs disposed around said tube unit, each of said support legs having a lower portion adapted to be disposed on a ground surface, and an upper portion sleeved on said outer wall surface of said tube unit, said upper portions of said first, second and third support legs being vertically aligned along the length of said tube unit, said upper portion of said third support leg being inserted through said gap and being sleeved rotatably on said outer wall surface of said tube unit in such a manner that said third support leg is rotatable relative to said tube unit, said lower portion of said third support leg being turned to said positioning element and said upper portion of said third support leg releasably engaging said positioning element when said stand is disposed at a position of use, said upper portion of said third support leg disengaging from said positioning element and said lower portion of said third support leg being turned away from said positioning element when said stand is disposed at a storage position; and a tongue-and-groove device for releasably retaining said upper portion of said third support leg on said positioning element when said stand is disposed at said position of use.
