Description

Lock with half-glitter

The invention relates to a lock comprising a stator (1) having a chamber (2) receiving a rotor (3) having a longitudinal slot (4) for the introduction of a part (5) of a control key (6) of flakes (7) housed in open passages (8) communicating with the longitudinal slot (4), said key (6) having one or more channels or notches (60) for receiving / guiding, for a series of flakes , a nose (70) of the straw (7) considered to move it against a return means (9) at least between a locked position for which the straw considered (7) extends at least partially out of the volume of the open passage (8) and partially in a housing for locking the stator (1), and an unlocked position for which the straw in question (7) extends essentially in the volume of an open passage (8) of the rotor (3).

In certain locks, each flake consists of a pair of adjacent half flakes (75,76) capable of moving each against a return means (9), namely for a pair of half flakes. adjacent flakes (75,76) moving in the same passage:

• a first half-flake (75) extending in a first plane perpendicular to the longitudinal axis (A) of the rotor (3), and moving at least partially in a first open passage (81) of the rotor (3) , and • a second half-glitter (76) extending in a second plane corresponding to said first plane.

Such locks are known and have been marketed in the past. Such a lock is thus taught in US 2,155,734.

Such locks are difficult to assemble and have often been the subject of attempted break-ins with forests. The destruction of flakes made up of two half flakes was easier than one-piece flakes.

BE2018 / 0078

The subject of the invention is locks of the type according to the first paragraph of this specification which are easy to assemble and which improve resistance to burglary.

The lock according to the invention is essentially characterized:

in that for some of the flakes (7), the flake consists of a pair of adjacent half-flakes (75,76) capable of moving each against a return means (9), know for a pair of adjacent half-glitters (75,76):

• a first half-flake (75) extending in a first plane perpendicular to the longitudinal axis (A) of the rotor (3), and moving at least partially in a first open passage (81) of the rotor (3) , and • a second half-flake (76) extending in a second plane corresponding to said first plane, and moving at least partially in a second open passage (8) of the rotor (3) distinct from the first open passage (81) for the first half-glitter (75) of the pair considered, and in that for a series of glitters (7) each comprising a pair of half-glitters (75,76), at least one series of first half-glitters ( 75) or a series of second half-flakes (76) cooperate with at least one longitudinal pin (100) extending in a longitudinal channel (110) of the rotor passing through open passages (81,8) of the series of first or second half-flakes (75,76) considered to limit and guide the movement acement of said half-flakes in part of their open passage.

Such half-flakes thus operate as independent flakes. The longitudinal pin (s) serve as guides for the half-flakes and as stops, preventing movements during attempts to open by not using the appropriate key. In addition, in the event of a break-in with a forest in the longitudinal slot of the

BE2018 / 0078 rotor, the longitudinal rod (s) are always active to oppose movements of the half-flakes or in the event of damage to one or more longitudinal rods, the rod (s) may twist preventing any movement half glitter. It has also been observed that the pin (s) can be used as an anti-vibration device when attempting to break into a forest.

The invention allows, according to embodiments, to obtain the following properties:

- a large number of independent flakes, for example 10 times or more than 10 times of pairs of independent half-flakes

- one two or more of two longitudinal crimping rods to retain the flakes or half-flakes

- one or more, for example 2 or 3 anti-drilling plates at the front of the barrel

- several independent housings for the ends of glitter in the stator, for example 4 independent housings at the end of half-glitter in the stator.

- use of a notched or channel key, for example with independent tracks, for example 2, 4 or more than 4.

- a large number of combinations.

- an improved level of security, no opening

- better resistance to forcing torque

- increased resistance to picking

- resistance to drilling

FIG. 1 is a perspective view of a rotor 3 and its key 6 with its flakes 7 (without representation of the springs 9) for a lock comprising a stator 1 with a chamber 2 suitable for receiving said rotor 3.

The rotor (3) has a longitudinal slot (4) for the introduction of a part (5) (for example flat with a profile defining a series of notches for actuating / flowing the movement of flakes during the introduction of the part 5 in the longitudinal slot) of a control key (6) of flakes (7) housed in open passages (8) communicating with the longitudinal slot (4), said key (6) having one or more channels or notches (60) for receiving / guiding, for a series of flakes, a nose (70) of the flake (7) considered to move it against a return means (9) (a spring) at least between a locked position for which the considered straw (7) extends at least partially outside the volume of the open passage (8) and partially in a stator locking housing (1) (an extreme part of the straw being in a housing of the stator to oppose a rotation of the rotor relative to its stat or), and an unlocked position for which the straw in question (7) extends essentially in the volume of an open passage (8) of the rotor (3) (when all

BE2018 / 0078 the flakes are in the unlocked position, rotation of the rotor is possible).

For some of the flakes (7), the flake consists of a pair of adjacent half flakes (75,76) capable of moving each against a return means (9), namely for a pair of adjacent semi-flakes (75,76):

• a first half-flake (75) extending in a first plane perpendicular to the longitudinal axis (A) of the rotor (3), and moving at least partially in a first open passage (81) of the rotor (3) , and • a second half-flake (76) extending in a second plane corresponding to said first plane, and moving at least partially in a second open passage (8) of the rotor (3) distinct from the first open passage (81) for the first half-glitter (75) of the pair considered.

For a series of flakes (7) each comprising a pair of half-flakes (75,76), at least one series of first half-flakes (75) or a series of second half-flakes (76) cooperate with a longitudinal pin (100) extending in a longitudinal channel (110) of the rotor passing through open passages (81,8) of the series of first or second half-flakes (75,76) considered to limit and guide the movement of said half-flakes in part of their open passage.

In the case shown, the half-flakes of the first series of half-flakes (75) and the half-flakes of the second series of half-flakes (76) each cooperate respectively with a longitudinal pin (100,101) extending in a longitudinal channel (110,111) of the rotor (3) passing through open passages (81,8)

For each of the half-flakes cooperating with a longitudinal pin (100, 101), the half-flake (75) considered moves in an open passage (8,81) in communication with the longitudinal slot (4) of the rotor. The passages 8,81 are interconnected by the longitudinal slot 4.

BE2018 / 0078

Said open passages 8,81 each have (a) a first part (810) defined between two plane faces (811,812) opposite and perpendicular to the axis (A) of the rotor (3), said two opposite faces (811,812) being separated from each other by a first edge (813) and a second edge (814) opposite to said first edge (813), (b) a second part (815) distant from the first part, and (c) a part intermediate (816) located between said first and second parts (810,815).

The open passages 8,81 are separated from each other by a portion of the rotor 3.

A longitudinal rod 100, 101 extends through the first part of an open passage for a half-glitter.

These longitudinal rods form a reinforcement between the half-flakes, thus making break-in more difficult, and increasing the resistance to rotation with an unsuitable tool.

Each half-glitter considered (75, 76) is a flat part comprising (a) a first portion (750) extending at least partially in the first part (810) of the open passage (81), (b) a second portion (751) extending at least partially in the second part (815) of the open passage, and (c) an intermediate portion (752) extending between said first and second portions (750,751). The first portion (750) has a first element (protrusion) or edge (800) adapted to slide along the first edge (814) of the first part (810) of the open passage (81) during a movement of the half -glitter (75.76); and a second edge (801) having (*) a section or part (801) remote from the second edge (813) of the first part (810) of the open passage (75) so as not to slide along the second edge ( 813) of the first part (810) of the passage open during movement of the half-flake considered, and (*) a protuberance (802) carried by said remote section, said protuberance (802) being advantageously adapted to be adjacent , even

BE2018 / 0078 slide along the second edge (813) of the first part (810) of the open passage (81) during movement of said half-glitter (75,76).

The pin (100,101) serves as a support means for the remote section (801) of the second edge (801) of the first portion (750) to guide the movement of said first portion (750) during a displacement of the half - straw, and abutment means for said protuberance (802) to limit the movement of said first portion (801) during movement of the half-straw (75).

The half-glitter considered (75, 76) has a nose (70) cooperating with the key to actuate the movement of the half-glitter. The pin (100,101) serves as a stop means for said nose (70) limiting the movement of said first portion (750) during movement of the half-glitter (75,76).

Each half-straw also has a protuberance 700 serving to support a spring intended to bring the half-straw back into a locked position.

The lateral surface 800 of this protuberance can be the surface sliding along the first lateral face 814 of the first part of the open passage.

The first longitudinal pin (100) and the second longitudinal pin (101) are diametrically opposite with respect to the longitudinal slot or to the axis (A) of the rotor (3).

FIGS. 2A and 2B show in section the rotor 3 in the chamber 2 of the stator 1.

In FIG. 2A, the longitudinal rod 101 is engaged in the channel 111. The front end of the channel 111 is protected by a half-plate 200 of high hardness. In Figure 2B we see the longitudinal rod 100 extending in the channel 110 parallel to the axis A of the rotor 3.

Figure 5 is a cross-sectional view of the rotor 3 in the locked position, front view, without the outer cover. As we can see from the ends of half glitter

BE2018 / 0078 extend under the action of the springs in separate housings 210,211,212,213 of the stator 1, which makes it possible to multiply the means of resistance to an improper unlocking.

It is indeed necessary to use a key making it possible to move all the noses 70 in an appropriate manner so that all the half-flakes extend in the cylindrical volume of the rotor 3.

FIGS. 6A and 6B are respectively a view of a pair of half-flakes in the locked position. Figures 6C and 6D are similar views but in the unlocked position.

Figures 13 A and B are views of a key with notches guiding the movement of the noses 70 of the half-flakes.

FIG. 14 is a view of half-inserts 200 of high hardness protecting the front part of the channels 110 and 111. The half-inserts also serve as abutment means to prevent the longitudinal rods from coming out once inserted by pressure into the rotor advantageously provided half glitter.

FIG. 17 is a view similar to that of FIG. 5 after a rotation of the rotor of approximately 45 °. As can be seen in this position, the rotor returns to a partial locked position, in the absence of the appropriate key. If the lock is not closed properly, rotating the rotor with an unsuitable tool will bring it back to a locked position.
