Abstract: A locking mechanism for a portable changing tent includes a puck body that houses a locking plate having a perimeter defined by at least three sets of alternating concave- and convex-shaped surfaces. A knob located at an uppermost end of the puck body rotates the locking plate between a fully unlocked and a fully locked position. The vertical centerline of the puck body's leg receivers is aligned with a corresponding horizontal centerline of the concave-shaped surface of the locking plate when the knob is in the fully locked position. The vertical centerline of each leg receiver is aligned with a corresponding horizontal centerline of the concave-shaped surface of the locking plate when the knob is in the fully unlocked position. Each concave-shaped surface of the locking plate urges against an end of a respective leg connector when the locking plate is in the fully locked position.
