Claim 1
Independent Claim
205 words
An extendible rack assembly comprising: a plurality of bars each of which has a pair of edges and a pair of ridges extending parallel along one side of each bar from one end to the other end, said pair of ridges having two inner faces opposing one another to define a groove in each bar; at least one connector piece for connecting adjacent ones of said bars end to end, said at least one connector piece having two pairs of opposing forked ends fitted in said grooves of said bars respectively, each of said pairs of forked ends consisting of a split pin with a recess; wherein said pair of ridges on each of said bars has two flanges projecting inwardly opposite to each other from edges of the ridges near ends of each bar, so as to retain said connector piece in said grooves, and two bosses oppositely projecting from said inner faces of the ridges towards each other so as to engage with said recesses of said split pins; and at least one hook member with a base means for mounting said at least one hook member over said bars so that said at least one hook member is slideable along said bars.
Claim 2
