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.

[ What is claimed is:] [1.] A shelf holder for a sectional rack, said sectional rack including upright posts with axially spaced annular grooves formed on outer circumferential surfaces thereof, and externally tapered sleeves having outer diameter gradually increased from top to bottom for firmly attaching to said posts by engaging inner flanges of said sleeves into said annular grooves around said posts, said shelf holder each comprising:a main part including a bar portion and at least one gripping ring portion connected to at least one end of said bar portion, a part of said gripping ring portion to an inner side of said bar portion being cut away to form an axially extended opening that has a width larger than an external diameter of each said post but smaller than an external diameter of said externally tapered sleeve; andat least one cooperative part pivotally connected to said bar portion of said main part, said at least one cooperative part including an arm portion and a seal portion connected to an outer end of said arm portion and having an arcuate extension projecting inward toward said gripping ring portion of said main part; said at least one cooperative part being connected at an inner end of said arm portion to said bar portion of said main part, such that when said cooperative part is horizontally pivotally turned toward said main part, said seal portion thereof finally engages with and closely covers the opening of said gripping ring portion of said main part to together with said gripping ring portion define a complete ring portion for tightly clamping said tapered sleeve therein; said arcuate extension of said seal portion being long enough to cross a line extending between a center of said gripping ring portion of the main part and a pivot axis of said arm portion of said cooperative part, such that when said seal portion is pivotally turned to close the opening of said gripping ring portion and thereby firmly enclose one of said tapered sleeves on said posts, said arcuate extension extends to abut against a part of outer wall of said tapered sleeve some distance away from said seal portion, preventing said seal portion from easily disengaging from said gripping ring portion, whereby said shelf holder with said main and said cooperative parts in an engaged state is tightly and stably mounted around said sleeve for supporting a shelf.
