Abstract

1. Lock key with compatible penetration stop (3) of which in its blade (2) have a penetration stop (3) that determines the position of said blade (2) inside the rotor (8) of the cylinder (7 ) and comprising a handle head (6) attached to the blade (2), characterized in that said penetration stop (3) is made up of two lateral fins (4) that protrude on both sides of the blade (2) as of lateral branches of a "T", being the width of the section of the blade (2) between the handle head (6) and the lateral fins (4) less than the width of the section of the blade (2) between the fins sides (4) and the end of the blade (2).

Description

DESCRIPTION

Lock key with compatible activation stop

FIELD OF THE INVENTION

This invention concerns a lock key with a compatible penetration stop, one of which has a penetration stop on its blade that determines the position of said blade within the cylinder rotor.

STATE OF THE PRIOR ART

At present and as a reference to the state of the art, it is common and known to use key penetration stops to correctly fix the position of the key in order to achieve a correct combination with the cylinder pins.

To achieve the aforementioned penetration stops, the keys have a greater width at the rear of their blade than the front part where the combination zone is located, said change of section empowering the key penetration stop.

However, said width at the rear of the blade prevents its correct use in a small-sized lock cylinder and / or an off-center lock cylinder, as there is a collision between the rear of the blade and the stator and / or the light bulb protective shield.

EXPLANATION OF THE INVENTION AND ADVANTAGES

Faced with this state of affairs, the present invention refers to a lock key with a compatible penetration stop, one of which has a penetration stop on its blade that determines the position of said blade within the cylinder rotor, in which said stop of penetration is constituted by two lateral fins that protrude on both sides of the blade like lateral branches of a "T" and there is a recessed area between the lateral fins and the handle head of the key.

Thanks to this configuration, it is achieved that the key can be used in a small-sized lock cylinder and / or an off-center lock cylinder, as the actuation stop is produced by the two "T" -shaped wings that the key presents. In this way, the rear part of the key blade can be narrower than the front part of the key blade where the combination holes are located, allowing it to rotate without colliding with the protective shield of the cylinder. .

Another characteristic of the invention is that on at least one of the sides of the blade there is a recessed area between the side wings and the handle head of the key.

Thanks to this configuration, it is achieved that keys with only one penetration stop can also be used in light bulbs of reduced dimensions and / or off-center bulbs without causing a collision between the rear part of the blade and the stator and / or the protective shield of the light bulb. .

These and other features of the invention will be revealed in the detailed explanation that follows, supported by the attached graphic representation.

EXHIBITION OF A PREFERRED EMBODIMENT

With regard to the above-listed drawings and references, a preferred mode of execution of the object of the invention is illustrated in the attached drawings, referring to a key (1) with a compatible penetration stop (3) of which in its blade (2) have a penetration stop (3) that determines the position of said blade (2) inside the rotor (8) of the cylinder (7), said penetration stop (3) is constituted in respective lateral fins (4) that they protrude on both sides of the blade (2) like side branches of a "T" and there is a recessed area (5) between the side wings (4) and the handle head (6) of the key (1).

As can be seen in figure 2, when inserting the key (1) into the rotor (8) of the cylinder (7), the lateral fins (4) are housed in the space between the stator (9) and the protective shield (10 ) of the bulb (7). In this position the penetration stop (3) comes into contact with the outer face of the rotor (8). In this way, the key (1) can be used in a lock cylinder (6) of reduced dimensions and / or an off-center lock cylinder (6), when the penetration stop (3) is produced by means of the two lateral wings (4) in the shape of a "T" that the key (1 ).

Another characteristic of the invention as can be seen in figure 1 is that on at least one of the sides of the blade (2) there is a recessed area (5) between the side wings (4) and the handle head (6) of the the key (1).

As can be seen in figure 4, when the key (1) is inserted into the cylinder (7), the lowered area (5) prevents the key (1) from colliding with the lock during the opening and closing operation of the lock. the lock shield by having the rear part of the blade (2) of the key (1) smaller than the front part of the blade (2) of the key (1) where the combination area is located.

Variations in materials, shape, size and arrangement of the component elements, described in a non-limiting manner, do not alter the essentiality of this invention, this being sufficient to proceed to its reproduction by an expert.

Claims (1)

1. Lock key with compatible penetration stop (3) of which in its blade (2) have a penetration stop (3) that determines the position of said blade (2) inside the rotor (8) of the cylinder (7 ) and comprising a handle head (6) attached to the blade (2), characterized in that said penetration stop (3) is made up of two lateral fins (4) that protrude on both sides of the blade (2) as of lateral branches of a "T", being the width of the section of the blade (2) between the handle head (6) and the lateral fins (4) less than the width of the section of the blade (2) between the fins sides (4) and the end of the blade (2).
