Abstract

Security lock with delayed opening, preferably of the type of borjas with seven guards, for double-bit wrench and two-stroke driving hammer, essentially characterized in that a disk-cam is mounted on the axis of rotation of the drive disk for the hammer able to rotate freely with respect to the first, against the tension of a spring, with the particularity that the drive disk incorporates a lug, through a perimetric neck of the disc-cam, and intended to impinge on a pivot threaded to a time mechanism, specifically to a cam disk of said mechanism, which is dragged by a first actuation of the key, for loading such mechanism, causing said pivot to impact on the staggering defining at the corresponding end of the neckline of the cam disk corresponding to the lock mechanism, for dragging the latter to a limit situation in which a square associated with this device co engages in a step defined in a swinging trigger, it being provided that both cam-disks incorporate two necklines in actual cam functions for an arm associated with the swinging hammer, so that when the lock is in the cam position mounted on the drive disc keeps said hammer inoperative while after the first actuation of the key, it is the cam disk corresponding to the time mechanism which maintains said position while the other disk-cam releases the arm of the hammer, establishing at the end of the timing, the appropriate confrontation between the necklines of both cam discs and tilting the hammer by the effect of an auxiliary spring until the dragging situation by the drive disk, in a second actuation of the key.
