Abstract: A padlock comprising a housing, a shackle, a lock mechanism and a movable block. The shackle is mounted on the housing and has a first end formed with a shaft portion movably mounted in the housing, and a second end formed with a locking portion moved with the shaft portion and extended outward from the housing. The lock mechanism is mounted on the housing, and includes a lock core and a limit knob. The lock core is mounted in the housing, and the limit knob is located outside the housing and movable by the lock core so as to engage or disengage with the locking portion of the shackle. The movable block is connected to the limit knob of the lock mechanism so that the movable block can be moved to an indication position by operating the lock core of the lock mechanism.

Abstract: By providing a single housing and shackle assembly constructed for enabling the shackle to be opened and/or closed using either a rotatable dial combination construction or a key activating tumbler construction, with the movement of the shackle being controlled by a trigger member, an effective, easily produced, padlock is achieved which incorporates two separate and independent locking systems formed in a single padlock. In addition, the trigger member and shackle each incorporate uniquely constructed, cooperating surfaces, each of which comprise a grooved zone or concave curved zone which is positioned directly adjacent a cooperating convexly curved zone. By employing these two curved surfaces on both the shackle and trigger member, the controlled pivotal movement of the shackle is realized.

Abstract: A programmable electronic lock with a closing tongue is actuated with an actuating mechanism formed by a mobile knob acting as a button joined to the closing tongue. Actuation of the mobile knob generates a movement of the closing tongue and closure of the lock. Recovery of the mobile knob to its initial position generates an opening of the lock. Furthermore, an electronics board is activated with a transponder key and controls operation of the lock by deactivating and subsequently activating a blocking mechanism formed by a motor that actuates a punch via a gear mechanism. When the punch is in a blocking position it is located against the actuating mechanism. When the punch is in an unblocking position, it is separated from the actuating mechanism and allows the movement of the closing tongue by unblocking the actuating mechanism.
