Patent ID: 8651300

Claim:
A sectional rack, comprising: a first discrete vertical support, comprising: a first laterally juxtaposed post; a second laterally juxtaposed post; a first connecting member; and a second connecting member, wherein said first connecting member and said second connecting members are connected to and between said first laterally juxtaposed post and said second laterally juxtaposed post, such that the space between said first laterally juxtaposed post and said second laterally juxtaposed post is defined by an identical connecting-member length of said first connecting member and said second connecting member; a second discrete vertical support; a third discrete vertical support; a fourth discrete vertical support; a first clamping member, comprising: a vertically extended receiving recess, sized for said first laterally juxtaposed post to partially surround said first laterally juxtaposed post, thereby allowing said first clamping member to assemble to said first vertical support with the open side of the vertically extended receiving recess facing away from said second laterally juxtaposed post of said first vertical support; a first wing portion, having a width that is increased from an upper end of said first wing portion to a lower end of said first wing portion, such that an outer surface of said first wing portion is a downwardly and outwardly inclined surface; and a second wing portion; a second clamping member; and a first shelf, comprising: a first corner; a second corner; a third corner; a fourth corner; a first C-shaped clamp, disposed and extending laterally from said first corner, further comprising: an opening facing laterally outward from said first shelf; a first end; a second end, wherein the space between said first end and said second end defines said opening of said C-shaped clamping member; a first inner end surface; a second opposite inner end surface, wherein said first inner end surface and said second opposite inner end surface are inclined so that a width of the inner space of said C-shaped clamp between said first inner end surface and said second opposite inner end surface gradually increases from top to bottom of said C-shaped clamp with a same gradient as the outer surface of said first wing portion and the outer surface of said second wing portion of said first clamping member, such that when said first inner end surface and said second opposite inner end surface tightly bear on the outer end surface of said first wing portion and the outer end surface of said second wing portion of said first clamping member, said first wing portion and said second wing portion are pushed toward each other, causing said first clamping members to tightly clamp on said first laterally juxtaposed post of said first discrete vertical support; a second C-shaped clamp, disposed and extending laterally from said second corner; a third C-shaped clamp, disposed and extending laterally from said third corner; and a fourth C-shaped clamp, disposed and extending laterally from said fourth corner.
