A playpen has a vertical pipe extending between first and second panels, an upper sleeve fixed to the first panel and receiving the upper end of the vertical pipe, a lower sleeve fixed to the first panel and receiving the lower end of the vertical pipe, elongated openings formed in the upper sleeve, an upper pin extending through the vertical pipe and the elongated openings, a locking lever turnable around the upper pin between first and second positions, a lower pin which interconnects the vertical pipe and the lower sleeve, an upper engaging member fixed to the second panel and disposed above the upper sleeve, a lower engaging member fixed to the second panel and disposed below the lower sleeve, and a distance defining member for defining the maximum distance between the upper and lower engaging members. The contact portions of the upper engaging member and the upper sleeve and the contact portions of the lower engaging member and the lower sleeve are formed with engaging raised and recessed portions, respectively, which are engageable with each other. When the locking lever is in the first position, relative turning movement between the first and second panels is allowed. When the locking lever is in the second position, relative turning movement between the first and second panels is inhibited.

A playpen having a plurality of panels for enclosing a given space, adjacent panels being turnably connected together, said playpen comprising: a vertical pipe vertically extending along the boundary line between first and second panels disposed at predetermined positions, an upper sleeve fixed to the upper end of the first panel and receiving the upper end of said vertical pipe, a lower sleeve fixed to the lower end of the first panel and receiving the lower end of said vertical pipe, vertically extending elongated openings formed in said upper sleeve, an upper pin extending through said vertical pipe and said elongated openings in said upper sleeve so that its opposite ends project beyond the outer surface of said vertical pipe, a locking lever attached to the projecting portions of said pin so that it is turnable around the axis of said pin between a first position and a second position, a lower pin which interconnects said vertical pipe and said lower sleeve so that they are rotatable in a unit, said upper sleeve being displaced downward along said vertical pipe when said locking lever is in said first position, said upper sleeve being pushed up for upward displacement along said vertical pipe by said locking lever when the latter is in said second position, an upper engaging member fixed to the upper end of the second panel and disposed above said upper sleeve, a lower engaging member fixed to the second panel and disposed below said lower sleeve, a distance defining member for defining the maximum distance by which said upper and lower engaging members can be separated from each other, the contact portions of said upper engaging member and said upper sleeve and the contact portions of said lower engaging member and said lower sleeve being formed with engaging raised and recessed portions, respectively, which are engageable with each other, the arrangement being such that when said locking lever is in said first position, said upper engaging member and said upper sleeve on the one hand and said lower engaging member and said lower sleeve on the other hand can be moved away from each other to the position where the engagement between said engaging raised and recessed portion is cancelled, thus allowing relative turning movement between the first and second panels, and when said locking lever is in said second position, said upper and lower engaging members having the distance therebetween defined by said distance defining member are in close contact with said upper and lower sleeves, respectively, so that the engagement between said engaging raised and recessed portions is maintained, thus inhibiting relative turning movement between the first and second panels.
