US Patent 7849867 Locking device for a tent

A locking device for a tent comprises a pole 2, a lock base 3 installed to allow hoisting/lowering of the pole, a lock hole 4 provided the pole, and a lock pin 5, provided movably within the lock base in the longitudinal direction, thus enabling the lock pin to be in a locking position to allow it enter the lock hole, or to be retracted to an unlocking position, to allow the lock pin to disengage from the lock hole. An elastic body 6 pushes the lock pin towards the locking position all the time. An operating lever 7 provided on the lock base can move the lock pin to an unlocking position; a coming-off prevention and holding means 8 allows the lock pin to be placed in a safety position for preventing accidental unlocking.
