• a pocket;
• a coupler to be removably received in the pocket when the coupler is in a first position;
• and
• a lever, the third frame member to operatively cause the lever to rotate, the rotation of the lever to cause the coupler to move from the first position to a second position in which the coupler is removed from the pocket, the third frame member to rotate via the second joint when the coupler is removed from the pocket to release the lock to enable the first frame member to move from an extended position to a collapsed position to fold the frame.
