Abstract

Device making it possible to display the blocking or unblocking of a latch or lock. The invention relates to a device previously fastened to a key and making it possible to display the blocking or unblocking of the latch or lock. It consists of a curved support 1 adjoining a hollow shaft 2, about which a body 7 can execute a rotation through half a turn in both directions, this occurring after the release of a dog 5 fixed to a pin 3 retracting during the insertion of the key, thus allowing the stud 8 fastened to the body 7 to exert pressure on the key 12, making it possible for the latter to block or unblock the latch.

Description

The present invention relates to a device pre
alably fixed on a lock or lock key,
allowing the blocking to be viewed at any time
or unlocking the lock or lock.

The device according to the invention comprises a body
hollowed out of a rectangular cavity and drilled right through
part in its length in which a hollow axis slides,
secured to a curved support in the middle of a half
cylinder, can be attached to this% r beforehand
cut and drilled, or of such manufacture, using
two rivets or some other way.

 The device according to the invention comprises a support curved in the middle of a half cylinder, adjoining a hollow axis in which slides a pin, pushed forward by a spring, it even crossed by a lug housed or dislodged of its cavity, according to the introduction or the extraction of the key, thus allowing the body to be blasted on the hollow axis of the curved support.

 According to a preferred embodiment, the device may be realistic, as far as the body is concerned, in molded and injected plastic, and in this case concerns the curved support, the hollow axis, in injected metal or by stamping, in that which concerns the pin and the pin in plastic or metal.

 The device represented in FIG. 1 comprises, a body (7) having dimensions of the order of 3 cm for the length, 3 cm for the width of 1 cm for the thickness rounded or not on the angles, pierced right through. part (17), hollowed out of a rectangular cavity (16) of 1.4cm x 1cm and of another rectangular cavity hollowed out in the thickness (I, adjoining in its thickness on a single end a stud (8) of 0 , 15cm in diameter and 0.5cm in length.

The device shown in Figure 1 comprises a curved support (1), with a thickness of C, 1cm having the approximate shape of a flat lock key, adjoining this support a hollow axis (2) of 0.8cm diameter, notched at its front end, with a light (j4) of 0.15 cm by 0.6 cm, inside this hollow axis (2), a pin (3) of 0.6 cm in diameter, crossed by a lug (5) 0.8 cm long and 0.15 cm in diameter. The said pin, cut from half its thickness over its half length, pushed forward by a spring (4) of 0.6 cm diameter, itself blocked by a ring (6) preventing by the same, the body (4) to come out of the hollow axis. (2)
the device according to the invention allows after the introduction of the dispositit provided with its key, in a bolt or a lock, the obligatory retraction of the pin (3) releasing the pin (5) from its housing (15). The lug then being in the cavity (14) allowing the body (7) a rotation of half a turn, thus forcing using the pin (8) on the key and its support, allowing blocking or unblocking of the bolt or lock, thus highlighting the acronym F (closed) to the acronym 0 (open).

After extraction of the key, the pin (3) returning to its original place thanks to the return spring (4), thus engaging the lug (5) in its housing, thereby preventing the necks (7) -of the device from turning around its hollow axis (2)

Claims (6)

 1) Device, previously fixed on a lock or lock key, allowing viewing at any time, blocking or unblocking the lock or the lock, characterized in that it comprises a body (7), capable of performing a rotation of a half turn in both directions around a hollow axis (2) adjoining a curved support (1) cylindrically in its center, after insertion of the key-in the lock, a-pin (3) retracting obligatorily, thus releasing a lug (5) from its housing, allows the body (7) a rotation of half a turn, thus forcing, using a stud (8) attached to the body (7), on the support and key to block or unblock the bolt or lock.  2) Device according to claim 1, characterized in that the pin (3) transpierced from its lug (5) constitutes a sliding part between the key (12) and the curved support (1).  3) Device according to claim 1 or claim 2 characterized in that a spring (4) tends to push forward the pin (3) pierced by its lug (5), which embedded in its housing, blocks the body (7) on the curved support (1).  4) Device according to any of the claims

 tions above, in that the body (7) can not released and make a rotation of half a turn, that the introduction of the key (12), the pin (5) being forced out inwardly , releasing the stud from its housing, the latter then being at the level of the cavity (16), the body thus released can rotate.  5) Device according to any one of the preceding claims characterized by a stud (8) fixed on the body (7) allowing after release of the pin (5), the stud (8) to force on the key (12) and the support (1) thus blocking or unblocking the bolt or the lock.  6) Device according to any one of the preceding claims, characterized in that the ring (6) allows the locking of the spring (4), of the pin (3), and of the body (7) of the device.
