During inflight bathroom break; the cockpit door was opened. Upon FA (Flight Attendant) entering flight deck; FO (First Officer) tried closing the cockpit door. Upon closing door; the door appeared to bind. Repeated attempts were made to try and close the door however the door was extremely warped. Flight Attendant later described what looked like spring near bottom of door. Flight landed at destination with Flight Attendant guarding door with cart blocking access until landing gear extension. First Officer utilized crash axe for defense and necktie to hold door closed. Armed LEO was informed of situation and to provide assistance in unlikely event of a level 4. A non-revning FA was also able to provide assistance. Dispatch was notified along with Maintenance Control. No guidance exists for cockpit door issues in flight.
