Abstract

Key (1) of lock with penetration stop (3) compatible of which in its blade (2) have a penetration stop (3) that determines the position of said blade (2) inside the rotor (7) of the bulb (6), characterized in that said penetration stop (3) is constituted in two lateral fins (4) projecting on both sides of the blade (2) as lateral branches of a "T" and existing a recessed area ( 5) between the side wings (4) and the handle head (6) of the key (1).

Description

DESCRIPTION

Lock key with compatible activation stop.

FIELD OF THE INVENTION

This invention concerns a lock wrench with a compatible penetration stop which has a penetration stop on its blade that determines the position of said blade 5 within the rotor of the bulb.

STATE OF THE PREVIOUS TECHNIQUE

 At present and as a reference to the state of the art, it is usual and known to use key penetration stops to correctly fix the position of the key in order to achieve a correct combination with the bulb's pythons. 10

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

 However, said width at the rear of the blade prevents its correct use in a small size lock bulb and / or an offset lock bulb, 15 when a collision occurs between the back of the blade and the stator and / or the protective shield of the bulb.

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, of which there is a penetration stop in its blade that determines the position of said blade within the rotor of the bulb, in which said penetration stop is constituted in two lateral fins that protrude on both sides of the blade as a 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 bulb 25 and / or an offset lock bulb, when the actuation stop is produced by the two "T" -shaped fins that the key has. In this way, the rear part of the key blade can have a smaller width than the front part of the key blade where the combination holes are located, allowing the rotation of the key without colliding with the light bulb shield . 30

Another feature of the invention is that on at least one of the sides of the blade 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 keys with only one penetration stop can also be used in small bulbs and / or off-center bulbs without causing a collision between the back 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 20

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

As can be seen in figure 2, when the key (1) is inserted into the rotor (8) of the bulb (7), the side wings (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 30 with the outer face of the rotor (8). In this way, the key (1) can be used in a small sized lock bulb (6) and / or an offset lock bulb (6), when the penetration stop (3) is produced by means of the two lateral wings (4) ) in the form of “T” that presents the key (1).

Another feature of the invention as 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 lateral fins (4) and the handle head (6) of the key (1).

As can be seen in figure 4, when the key (1) is inserted into the bulb (7), the lowered area (5) prevents that during the opening and closing of the lock, the key (1) does not collide with the shield of the lock when arranging the back part of the shovel (2) of the 40

key (1) smaller than the front part of the blade (2) of the key (1) where the combination zone 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, it being sufficient to proceed to its reproduction by an expert. 5

Claims (1)

1st.- Key (1) of a lock with a penetration stop (3) compatible with those on its blade (2) have a penetration stop (3) that determines the position of said blade (2) inside the rotor (7) of the bulb (6), characterized in that said penetration stop (3) is constituted in two lateral fins (4) that protrude on both sides of the blade (2) by way of lateral branches 5 of a "T" and there is an area lowered (5) between the side wings (4) and the handle head (6) of the key (1). 2 .- Key (1) lock with penetration stop (3) compatible, according to claim 1, characterized in that at least one of the sides of the blade (2) there is a recessed area (5) between the fins sides (4) and the handle head (6) of the key (1). 10
