Abstract

Improved lock, of the type comprising two knobs that actuate the drive mechanism and a carrier housing of the sliding pin, with basic washers in the knobs for support of the assembly on the door and perforations in washers and box-passer for fixed stems for linking and fixing the components of the lock; characterized in that said knobs have in their hollow interior, cylindrical bodies, honeycombed in sectors according to the axis thereof, with rotation around fixed, axial bushings, provided with elastic retaining rings, externally, of said cylindrical bodies and planes basic perpendicular; said basic planes of the bushings presenting perpendicular extensions of fixation, by means of screws, to the fixed connecting rods of the components of the lock; also presenting the aforementioned cylindrical bodies, each eccentric actuating lugs on the pin thereof; and in that the carrying case of the sliding pin, of rectangular prismatic configuration and constituted by two articulated symmetrical covers, has one of its smaller open bases, provided with fixing wings to the door, on the base of which the bevelled end of the pin protrudes in the closed position, its opposite base being closed and presenting in the area next to it, perpendicular to its major planes, the corresponding perforations for the passage of the fixed connecting rods with the knobs, and a semicircular groove for the passage of the eccentric lugs for the actuation on the pin, whose internal core presents in the same zone housings configured for the action of said lugs; and because the armours of the knobs, connected to the internal cylindrical bodies, by articulations of longitudinal projections of the latter in corresponding guides thereof, constitute, by means of their eccentric actuating lugs on the pin, the assembly of the latter from the interior of the latter. The carrier box, in the open position; and because recovery springs, housed in various recesses of the pin inside the carrier box and spiral springs, located between the bases of the movable cylindrical bodies and the fixed bushings, constitute the driving elements for recovering the system to the closed position.
