Abstract:
A knock-down display shelf, comprising:a locking sleeve including a pair of semi-tubular halves;a retaining cap including a circular bottom flange and a tubular vertical wall forming a central hollow portion;each said semi-tubular half including a limiting rib defined on an inner face thereof and including a protruded lug at one end and an engagement recess at the other end so as to permit said paired halves to be interlocked together in assembly;said circular bottom flange of said retaining cap including a plurality of screw holes;said tubular vertical wall of said retaining cap including a plurality of axial splits defined thereon and a tapered inner face;said display shelf including a top board and a plurality of rest boards mounted in parallel onto four vertical supporting pillars;said top board including a circular cavity at each corner thereof being mounted to a top end of said supporting pillars;each said rest board including a countersunk through hole at each corner thereof so as to permit each said retaining cap to be fitted in and secured in place by screws in said countersunk through hole;each said supporting pillar including a plurality of spaced ring grooves so as to permit one said locking sleeve to be selectively engaged with one of said ring grooves by way of the limiting rib of said semi-tubular halves that are interlocked together thereafter;one said rest board being mounted onto said four supporting pillars with said locking sleeve being secured to each said supporting pillar at the same level so as to permit each said retaining cap housed in each said counter sunk through hole to be in tight engagement with a corresponding locking sleeve, free of shaky connection in assembly;said axial splits of said retaining cap permitting said rest board to be readily disengaged from said locking sleeve when dismantled for position arrangement.
