Abstract
A sectional rack is constructed from multiple vertical supporting posts, horizontal shelves and connecting members. The supporting posts have a non-round cross section and the shelves have short sleeves provided at every corner thereof. Each supporting post is provided on its outer surface at a portion facing inward toward the rack with a plurality of equally spaced grooves. Each connecting member is adapted to firmly mount on the supporting post by engaging ribs provided on inner surface of the connecting member with the grooves on the supporting post. An outer surface of the connecting member opposite to the ribs is downwardly and outwardly inclined; and an inner surface of the sleeve of the shelf facing the inclined outer surface of the connecting member is correspondingly inclined. The association of the sleeve with the connecting member causes the inclined inner surface of the sleeve to apply a pressure on the inclined outer surface of the connecting member to force the ribs of the latter further into the grooves on the supporting post and thereby ensures stable connection of the shelf to the supporting post.
