The invention relates to a mechanical system for blocking and opening in a lock that can be actuated via a key with a linear movement, without rotation, which does not therefore require a rotation of the key to actuate the opening mechanism, not including any kind of cylinder system. Same comprises two complete parts, as shown in FIG. 1, a special key (1) and the system comprising the set of parts forming the lock. Upon introducing the key with a simple linear movement, and without needing to rotate same, the different mechanical actions are triggered that permit the unblocking of the lock, such that the individual notches of the key press on readers (2), which are to be calibrated, and, only if the position is correct, the mechanisms permitting the opening are released. Same is particularly applicable in embedded locks for all door configurations.
Mechanical blocking and opening system in a lock actuated by means of a key with linear movement without rotation, wherein a flat key participates therein, at the end of which a profile having a series of notches is defined, said lock itself being provided with a shield, with the corresponding slot for the key to pass through, being defined, inside the lock, a body of the key mechanism wherein a plurality of readers-feelers can be displaced by the end of said key being pressed against them, readers-feelers that have at the upper part thereof a series of notches that are aligned upon displacing through the correct profile of the key, said displacement being regulated by means of a distance gauge which is arranged just before the body of the key mechanism, in such a way that the distance gauge abuts the pushing shaft of the gauge, which displaces a bridging piece of a retaining plate being vertically displaced inside said bridging piece, such that in the body of the key mechanisms two notches are defined which are aligned to the notches alignment when inserting the correct key, all this assembly defining an accommodation for the retaining plate to be vertically fitted in, which comprises at the end thereof a flange which during the axial displacement caused by the key insertion displaces a washer, with an orifice that, when being in a stand-by condition, tends to be biased by the action of a spring, with respect to an orifice drilled in the body of the key mechanisms, said orifice through which a bolt is vertically displaced, which during the lower displacement thereof, presses onto a pawl acting as a rocker which in turn lifts an opening flange as a retaining element of an opening leg that tends to retracting the tongue by pulling thereof through a lug by the action of a spring, this tongue being in turn associated to a spring by means of which it is urged towards its extracting position and to the blocking position for the lock.
