发明名称 Keyed gate latch
摘要 A gate latch including a body-mounted latch bolt which may be actuated to an elevated position from outside the gate by a lever extending through the gate to disengage the bolt from the latch strike. A lock device is provided which may be key-operated on the outside of the gate to locate a detent or cam element in a position to prevent movement of the lever, thus preventing the gate from being opened from the outside. Additionally, or alternatively, a cam or crank-like element may be actuated by the lock to prevent rotation of the latch bolt to unlock the gate. The element may be mounted so as to have a relatively slidable portion thereon which is actuatable, against a spring biasing force, to allow the bolt to be rotated, by one of the inside of the gate, to open the gate.
