Patent ID: 6971528

Claim:
A connecting structure for sectional rack, comprising: a plurality of vertical posts, a plurality of horizontal shelves, a plurality of connecting members, a plurality of pads adapted to attach to said connecting members, and a plurality of outer covers separately provided at each corner of said horizontal shelves for engaging with said connecting members and said pads; each of said vertical posts being provided with at least one row of engaging holes, with which said connecting members are engaged to attach to said vertical post; each of said connecting members being provided at a first end with upper and lower hooks adapted to extend into two vertically adjacent engaging holes on said vertical post and thereby holding said connecting member to said vertical post; a second end of said connecting member opposite to said first end being located outside said vertical post and formed into a hooking section for engaging with said outer cover provided at each corner of said horizontal shelf; each of said pads having a first side adapted to fitly bear against an outer surface of said vertical post, and a second side of said pad opposite to said first side being a downward and outward inclined surface; said pad being provided at predetermined positions with upper and lower openings, through which said upper and lower hooks of said connecting member are adapted to be passed to engage with said pad and extend into said engaging holes on said vertical post; and each of said outer covers having an open outer side facing toward said vertical post and an open bottom, and being provided with two internal walls, which are downward and inward inclined surfaces adapted to fitly bear against said inclined surface at the second side of said pad when said pad is associated with said connecting member and covered by said outer cover; whereby when said outer cover is fully engaged with said connecting member and said pad that have already been connected to said engaging holes on said vertical post, said inward inclined surfaces of said outer cover apply a pushing force against said inclined surface of said pad to firmly push said pad against the outer surface of said vertical post, while said outer cover pulls said connecting member outward via said hooking section to tightly press said upper and lower hooks of said connecting member against inner sides of said engaging holes, causing said outer cover, said connecting member, said pad, and said vertical post to tightly connect to one another for said horizontal shelf to be stably supported on said vertical posts.
