  • Patent number: 8038021
    Abstract: A sectional rack, which can be assembled without using fastening elements and tools, includes rectangular vertical posts, foot members connected to lower front and lower rear ends of the vertical posts, hook members hooked to hanging holes provided on lateral faces of the vertical posts, and crossbars mounted to lower and higher positions between two adjacent vertical posts via the hook members. When the hook member is hooked to the hanging holes, an insertion slot is formed between the hook member and the lateral face of the vertical post. The crossbars are respectively formed on a lower portion at each of two lateral ends with an insertion section for firmly downward inserting into two insertion slots formed on two facing lateral faces of two adjacent vertical posts, so that the two vertical posts are supported by the crossbars to stably stand upright.

The first hooking member has two sideward projected hooks for firmly located in two insertion holes on a rear post of a sectional rack. The second hooking member includes two sideward projected lugs for fitly inserting into two insertion holes on a front post of the sectional rack to prevent the rail from moving up or down, and two vertically movable hooks bearing against one side of the two lugs for extending into and hooking on the same insertion holes to firmly hold the rail to the front post. Therefore, the rail may be stably hooked on the posts of the sectional rack for a drawer or the like to safely slide thereon.

  • Patent number: 6901633
    Abstract: A door hinge is adapted to connect a door to a vertical metal post of a sectional rack, so that an enclosed storage space may be provided on the sectional rack. The door hinge includes a fixing member for connecting to the door, a hanger for hooking to the vertical post, an adjusting member connected to the hanger, and a turning member, a spring leaf, and a torsion spring mounted between the adjusting member and the fixing member. A cushion pad is positioned between the hanger and the post and forced against the post by a tightening screw, so that two hooks provided on the hanger may be tightly engaged with hook eyes provided on the post. The door connected to the fixing member may therefore be pivotally connected to the vertical post.
