ABSTRACT:
Improved locking sleeve assembly is intended for use on a knock-down display shelf which is made up of four supporting pillars, multiple inner sleeves, rest boards, a top board and a plurality of retaining caps. Each locking sleeve assembly is made up of a separable inner locking sleeve and a retaining cap which has a roundly flanged bottom and a hollow central tubular portion provided with a tapered inner surface. On the circular flange of each retaining cap are disposed a number of counter sunk screw holes. At each corner of a rest board is disposed a counter sunk through hole in which a bottom flanged retaining cap can be placed and fixed in place by screws engaged with the screw holes on the circular flange. Each supporting pillar has a plurality of equally spaced peripheral grooves so as to permit halves of the separable locking sleeves, each having a peripherally extended rib on the inner surface, to be selectively engaged with the grooves of a supporting pillar at various levels. Each retaining cap has a number of axial splits on the wall of its hollow central portion for permitting the retaining cap to be flexibly operated. In assembly, the locking sleeves are engaged with the 4 supporting pillars at different levels with every 4 sleeves located at the same level, then a rest board is engaged with the 4 supporting pillars with the counter sunk through holes, each having a retaining cap engaged therewith, of the rest board guided through the 4 supporting pillars. The tapered retaining caps can firmly and tightly engaged with the locking sleeves so as to support rest boards in place. To dismantle the display shelf, the splitted retaining caps are easily disengaged with the locking sleeves along with the rest boards.
