inserted in a conjunction of the corner member
10
and a pair of rails
12
respectively pivoted the perpendicular upper portions by screws
13
and nuts

can be flattened or collapsed.
However, this type of corner member
10
is assembled or disassembled with tools. Therefore, it is inconvenient and the screws
13
may be loosened.
SUMMARY OF THE PRESENT INVENTION
The present invention has a main object to provide a structure of corner member for a playpen which is assembled or disassembled without using a tool and the assembly is stable and will not be loosened.
Accordingly, the structure of corner members for a playpen of the present invention comprises a plurality of corner members each of the corner members has a hollow interior L-shaped seat, a vertical sleeve in the conjunction for engaging with a vertical post, a projection projected upward from the top of the conjunction, a plurality of arcuate grooves spacedly formed in the top of the two arms of the L-shaped seat, a pair of rectangular thru holes spacedly formed in the grooves and a pair of L-shaped slots respectively in the rectangular thru holes each having a transverse portion for pivoting a pair of rails by a pair of retaining pins; a L-shaped cover covering the top of the seat. The cover has a plurality of inwardly arcuate strips made engageable with arcuate grooves of the seat, a vertical rod made engageable with the vertical portion of the L-shaped slot, a hollow interior projection at the conjunction engageable with the projection of the seat and an insertion plate at the conjunction of the seat engageable with the positioning slot of the cover. Therefore, the above discussed elements are assembled or disassembled without using a tool.
