Title: Animal pen construction

Abstract: An animal pen construction having sidewalls and a gate which are formed from a plurality of prefabricated modular rail sections. These rail sections have cooperating male and female portions on opposite ends to permit the sections to be slidably telescopically connected together. A single universal post member is utilized both in a straight run along the sidewall, and as a corner or gate post, for supporting the walls in an upright position. The posts permit from one to four connections thereto, which connections can run straight through the post or at right angles thereto. A latch structure cooperates between the gate and the associated post to permit horizontal swinging of the gate into an open position. This latch structure also functions as a hinge so that provision of this latch structure adjacent each edge of the gate enables the gate to be hingedly opened about either edge thereof.
