ABSTRACT:
An easy-mount shelf holder for a sectional rack. The rack includes upright posts having spaced annular grooves for externally tapered sleeves attached thereto and shelves supported by shelf holders mounted around the sleeves. Each shelf holder includes a main part formed from a bar portion and a partially opened gripping ring portion provided at one end of the bar portion, and a cooperative part formed from an arm portion and a seal portion provided at an outer end of the arm portion. The cooperative part is pivotally connected at an inner end of the arm portion to the bar portion of the main part, such that when the cooperative part is turned toward the main part, the seal portion closes the partially opened gripping ring portion to define a complete and internally tapered ring portion suitable for tightly enclosing the tapered sleeve on the posts. An arcuate extension of the seal portion firmly abuts against a part of outer wall of the sleeve some distance away from the seal portion when the sleeve is tightly clamped by the ring portion, preventing the seal portion from easily disengaging from the gripping ring portion. The position of the shelf holder on the post can be adjusted by simply pivoting the cooperative part away from the main part to loosen the seal portion and the gripping ring portion from the sleeve.
