Definitions
- the present invention relates to a movable push key, a safety barrel for said key and a lock or bolt fitted with such a barrel.
- a key is described, the elongated flat body of which is provided with a housing inside which a movable pusher such as a ball can move in a movement of limited amplitude.
- the housing of the movable pusher is formed in the thickness of the key body perpendicular to the mean plane of said body. It can be opened at its two ends and lead, on each side, to one of the two large faces of the key body.
- the ball which acts as a movable plunger has a diameter which is substantially equal to or slightly less than the thickness of the key body in which it is housed.
- a positioning member which cooperates with the movable pusher of the key body, may consist of a fixed rotor pin, that is to say a pin which is carried, without the possibility of axial movement , by the rotor, and which projects inside the key channel.
- the mobile push key described in the aforementioned French patent is generally satisfactory, but it nevertheless has a triple disadvantage: first, the mobile push button is housed in the thickness of the key and being a ball, its diameter is necessarily small because it must not exceed the thickness of the open-end wrench. However, it is necessary to produce push-button housings and end-of-travel stops which are perfectly dimensioned, which constitutes a considerable practical difficulty due to the small dimension of these elements.
- the pusher can only have an extremely short stroke and, consequently, only protrudes slightly outside its housing, when it is pushed by the fixed rotor pin.
- the movable pin of the rotor associated with the movable pusher of the key body does not protrude inside the channel of key but is, on the contrary, set back relative to the wall of the key channel. Indeed, the picking of the lock barrel is greatly complicated or even made impossible, if the movable rotor pins do not protrude inside the key channel.
- the groove necessary for the passage of the fixed rotor pin which projects inside the key channel is formed on one of the longitudinal edges of the key body; it is therefore no longer on one of the two large faces of the key body and the latter can receive recesses on their entire surface.
- the pusher housing and the pusher have had a length substantially equal to the width of the key body and no longer equal, as in the aforementioned French patent, to the thickness of the key body; given the larger dimensions of these elements, the required machining tolerances are easier to maintain.
- the movable pusher can also have a greater stroke inside its housing, so that the associated movable rotor pin can be arranged much further back from the wall of the key channel than the retaining pin. corresponding rotor described in French Patent No. 2,492,872.
- FR-A 2 521 201 The solution described in FR-A 2 521 201 is interesting and gives satisfaction. However, it requires the presence of the grooves, mentioned above, for the passage of the fixed pin, which somewhat complicates the manufacture of the key, and limits the possibilities of using its edges.
- the movable pusher can project transversely, relative to the maximum transverse dimension of the key; this results in a risk of the mobile pusher catching on the walls limiting the housing of the rotor, when the key enters this housing; practically, it is necessary to provide a frustoconical surface at this entrance, this surface constituting in a way a ramp sliding the movable pusher in its housing in the case where this pusher exceeds the housing.
- European patent n ° 154 755 describes a key for a safety barrel, usable in particular for the operation of a lock or a bolt, said key comprising a key body of elongated flat shape which is intended to penetrate into a channel of key of the barrel rotor, the key body comprising at the top a narrowed zone in height in which is provided at least one through housing extending transversely relative to the longitudinal axis of the key and being substantially parallel to the mean plane of the body key to lead to the opposite edges of the narrowed area, said housing receiving a movable pusher capable of translating in a movement of limited amplitude, said pusher being intended to cooperate by one of its transverse ends with a positioning member outside the key which is provided in line with the longitudinal opening of the rotor key channel, so as to push, by its transverse end oppo sée, a movable rotor pin in a position allowing the rotation of the rotor relative to the stator of the barrel.
- the object of the invention is to propose a key for a safety barrel, in which the movable push-piece further complicates the duplication of the key which is equipped with it, to provide the user with increased security.

- the rotor 4 has a key channel 8 whose cross section is rectangular and slightly greater than that of the key body 3 so that the latter can penetrate inside the channel 8.
- This key channel 8 is formed by a through groove extending over the entire length of the rotor 4 and opening onto the cylindrical outer surface of the rotor 4 by a longitudinal opening 9.
- the wall of the key channel 8 opposite this opening 9 constitutes the bottom 8a of the channel, the bottom 8a being connected to the outer surface of the rotor 4 by two substantially parallel side walls 8b.
- the rotor 4 has a protrusion in the form of a projection 10 intended to slide in the longitudinal groove 3e on the upper edge 3c of the key body 3 (see FIG. 3).
- the double barrel here comprises two stators 7 which are connected by a longitudinal beam 11, each stator 7 receiving a respective rotor 4.
- each rotor has an external peripheral groove (visible at 12 in FIG. 3) which is intended to receive a circlip 13 for longitudinally locking each rotor inside its associated stator.
- a bit 14 for the operation of the lock members.
- the bit 14 comprises a cylindrical collar which is carried by the two axially internal ends of the rotors 4, said collar being provided with a median web 15.
- the bit 14 also comprises, arranged radially with respect to the collar, an operating lug 16.
- a driver not shown, is intended to couple / disengage the bit 14 to the rotors 4, depending on the presence or absence of a key in the associated rotor.
- each rotor 4 and the associated stator 7 are provided by movable rotor pins such as pins 18 and 19 illustrated in Figure 9, which are associated with corresponding stator movable pins 20, 21.
- the movable rotor pins 18, 19 are slidably mounted in a respective housing 22, 23 provided radially in the rotor 4, each housing comprising two sections of different diameters delimiting between them an annular shoulder 22a, 23a.
- Each housing 22, 23 opens by its section of smaller diameter, inside the key channel 8, and by its section of larger diameter, on the cylindrical outer surface of the rotor 4.
- Each pin 18, 19 also has two parts of different diameters, corresponding to those of the two sections of the housings 22, 23, namely a part forming a rod connecting to a part forming a head of larger diameter 18a, 19a.
- Each head 18â, 19a is in abutment against the corresponding stator pin 20, 21 which is formed by a kind of hollow cap, slidably mounted in a respective radial housing 24, 25 of the stator 7.
- Each stator pin 20, 21 is pushed elastically by a spring 26 against the head 18a, 19a of the rotor pin 18, 19.
- the housings 22, 24 and 23, 25 have their axes aligned.
- each movable rotor pin When the key body 3 is not introduced through the key channel 8, the head 18a, 19a of each movable rotor pin is pushed by the respective stator pin 20, 21 against the shoulder 22a, 23a of the respective housing 22, 23.
- the depth of the section of larger diameter of the housing 22, 23 is greater than the thickness of the head 18a, 19a so that the stator pin 20, 21 penetrates into the section of larger diameter of the housing 22 , 23, the diameter of the housing 24, 25 being the same as that of the section of larger diameter of the housing 22, 23.
- any rotation of the rotor 4 relative to the stator 7 is prevented by the stator pin 20, 21.
- FIG. 4 several housings 23 for movable rotor pins are illustrated along the rotor 4.
- the movable rotor pins 18, 19 are pushed back against the springs 26 by recesses (not shown) provided along the key body 3 on its large side faces, or by serrations (not shown) on the edges of the key body. If the correct key is not used, the head 18a, 19a of the movable rotor pin 18, 19 will protrude into the housing 24, 25 of the stator 7 and will prevent the relative rotation of the rotor 4 relative to the stator 7.
- the head of the key 1 has a narrowed area 30 in which is formed a through housing 31 extending transversely to the longitudinal direction of the key and substantially in the mean plane of the key body 3.
- the narrowed area 30 has the same thickness e as the rest of the key body 3, but its height h (FIG. 1A) is reduced compared to the height H of the rest of the key body 3.
- the housing 31 opens, at its two ends, on the edges of the narrowed zone 30.
- a movable pusher 32 which is intended to cooperate with a positioning member 33 formed, in FIGS. 3, 4 and 9, by a plate or wedge embedded in a recess provided in the opening 9 of the channel of key 8 of rotor 4, said plate 33 projecting radially inwards from key channel 8 by a rib 33a having in the mean plane of key channel 8 a convex surface whose convexity is directed towards the bottom 8a of the channel key 8 to allow a progressive movement of the movable plunger 32 upwards at the end of introduction of the key into the barrel.
- the outer surface of the plate 33 follows the outer cylindrical surface of the rotor 4 so as not to hinder the rotation of the rotor relative to the stator.
- the plate 33 is fixed by any suitable means to the rotor 4, in particular by force-fitting into the recess of this rotor.
- the axial locking of the rotor 4 relative to the stator 7 is provided, on the one hand, by a flange 28 provided at one end of the rotor and cooperating with the stator 7, and on the other hand , by the split elastic ring 13 anchored in the groove 12 provided on the outer surface of the rotor 4 towards its end remote from the flange 28, this ring 13 cooperating with the other end of the stator 7.
- the narrowed zone 30 comprises on each of its large lateral faces 30a, 30b at least one orifice 34 opening into the transverse housing 31.
- the orifices 34 have a shape which is substantially flared towards the outside , for example frustoconical, the axis of which is aligned with the axis of a movable lateral pin of the rotor, such as the pin 19, when the key 1 is inserted into the barrel.
- This plunger consists of a small flat plate 35 extending substantially in the mean plane of the key body 3, said plate 35 comprising at each transverse end a projecting edge 36a, 36b intended to cooperate respectively with the positioning member 33 and a movable pin of the rotor, such as the bottom pin 18.
- the plate 35 further comprises an extension longitudinal 37 which has a transverse dimension l less than the height h of the narrowed zone 30, said extension 37 being received in a blind recess in the housing 31 to limit the amplitude of the sliding of the pusher 32 and to prevent this pusher from escaping of its housing 31.
- this extension 37 nevertheless allows the pusher 32 to partially leave the housing 31 beyond the edges of the narrowed zone 30, and protruding transversely relative to the contour of the cross section of the rest of the key body 3 when the pusher is out of its housing to the maximum.
- the housing 31 is completely open at its two transverse ends to allow the introduction of the movable plunger 32, then, after insertion of the plunger, the extension 37 of the plunger is crimped into the housing 31 by discharge of material from the end of the key, in order to define the abovementioned blind recess.
- the pusher 32 has a transverse dimension substantially greater than the height h of the narrowed zone 30 and less than the height H of the rest of the key body 3, but one could also provide a pusher having a transverse dimension equal to or even less than the height h of the narrowed zone 30, the movable rotor pin 18 can then partially penetrate into the housing 31 of the pusher.
- the pusher 32 further comprises, on each large lateral face of the plate 35 a projecting rib 38, 39 extending in a plane substantially perpendicular to the longitudinal direction of the key.
- Each rib 38, 39 comprises a notch or a groove 40, 41 having a general V shape open towards the side walls 30a and 30b of the narrowed zone 30 and extending in the transverse direction of the housing 31.
- the notches 40 and 41 are positioned on the ribs 38 and 39, so as to be located substantially in line with the orifices 34, so that the lateral movable rotor pins can come into contact with the slope of a branch of the V through the orifices 34.
- the slopes of the V make it possible to define several possible contact positions with the movable lateral rotor pins.
- the notches 40 and 41 on each face of the pusher 32 can be positioned at a different height in the transverse direction.
- the notches 40 and 41 extend over at least part s of the segment defined between the two extreme planes PI and P2 of straight section of the pusher. In other words, the length of the notches is less than that of the pusher in the axial direction of the key body.
- the housing 31 of the narrowed zone 30 of the key has a profile complementary to the pusher 32.
- the pusher 32 is in its maximum projecting position relative to the narrowed zone 30, in the direction of the movable rotor pin 18 which is located on the bottom 8a of the key channel 8 and aligned with the transverse direction of the pusher 32.
- the movable pusher 32 is supported by its lower projecting edge 36a at the top of the convex rib 33a of the positioning wedge 33, and by its opposite projecting edge 36b on the frustoconical end of the movable pin 18.
- the projecting edge 36b here penetrates inside the housing 22 of the rotor pin.
- the lateral movable pin 19 of the rotor 4 passes through an orifice 34 in the narrowed zone 30 and comes to bear by its rounded end substantially in the center of the V of the notch 41 of the pusher 32, or at the bottom of the slope of a branch of the V.
- the line for another lateral movable rotor pin has been indicated in broken lines 123.
- the pin 18 has been replaced by a pin 118 forming an acute angle with the mean plane of the key channel 8.
- This pin 118 also opens onto the bottom 8a of the key channel 8, but is intended to be supported on one side of the projecting edge 36b of the pusher 32.
- This pin 118 here has a rounded end. Consequently, the pin 118 has a length substantially greater than that of the pin 18, since the end of the pin 118 does not come to bear at the top of the protruding edge 36b of the pusher 32.
- the positioning wedge 33 is replaced by another positioning wedge 133 which has a convex rib 133a of lower height. Therefore, the upper projecting edge 36b of the pusher 32 is positioned at a different height relative to the housing 31 of the narrowed area 30 of the key.
- the movable pin of the rotor 218 which is in the mid-plane of the key channel 8 therefore has a length greater than the pin 18, to allow the unlocking of the barrel, when its frustoconical end comes into contact with the edge 36b of the pusher 32.
- a lateral pin 119 comes into contact with the notch 41 of the pusher 32 in a different position.
- the pin 119 comes into contact substantially halfway up the slope of the V of the notch 41. Therefore, the pin 119 must have a length less than the pin 19 above.
- the bottom pin 318 is inclined relative to the mean plane of the key channel 8 and comes into contact on one side of the upper edge 36b of the pusher 32, in a similar manner to the pin 118 of the figure 10.
- the positioning shims 33 and 133 have on either side of the convex rib 33a, 133a of the fins 33b, 133b extending in opposite directions in a direction perpendicular to the mean plane of the key channel 8, which are intended to s '' insert into a conjugate housing of the rotor.
- the positioning shims 33 and 133 are deleted and it is the internal cylindrical surface of the bore 7a of the stator 7 which serves as a positioning member for the lower projecting end 36a of the pusher 32.
- the pusher 32 is then in the maximum projecting position downwards, its upper end edge 36b flush with the upper edge of the narrowed zone 30 of the key.
- the rotor pin 418 which is in the middle plane of the key channel 8 must have a length greater than the pin 218 above.
- a lateral rotor pin 219 is supported at the top of a slope of the notch 41 in V of the pusher 32. Therefore, the pin 219 must have a length less than the pin 119 cited above.
- the length of the movable rotor pins can be varied at the level of the narrowed zone 30 of the key 1, as a function of the height of the positioning member, thanks to the presence of the notches which define several different degrees of driving the pins into the key.
- FIGS. 19 to 24 show a pusher 132 according to an alternative embodiment.
- the elements of the pusher 132 which are analogous to the elements of the pusher 32 bear the same reference number increased by 100.
- the pusher 132 differs from the pusher 32 only in that the notches 140 and 141 have a general V-shape truncated at the base or a C shape with divergent side branches.
- the flat base of the V is here slightly inclined relative to the transverse direction of the movable pusher 132.
- FIGS. 19 to 24 represent another embodiment of the key of the invention.
- the elements which are analogous to the elements of FIGS. 1 to 7 bear the same reference numbers increased by 200.
- the pusher 232 comprises on each side face of its small plate 235 a pair of parallel ribs 238, 258 and 239, 259 which respectively comprise notches 240, 260 and 241, 261.
- the notches of the pusher 232 have a general V shape, one of the branches of which is more inclined than the other relative to the mean plane of the pusher.
- the ribs 238 and 239 located on either side of the pusher 232 are preferably in the same plane perpendicular to the longitudinal axis of the key.
- the ribs 258 and 259 on each side of the pusher 232 are located in the same plane perpendicular to the axis of the key.
- the two ribs 238, 258 which are located on the same face of the pusher 232 preferably have their respective notches 240 and 260 arranged in opposite directions.
- the notch 240 has the longest branch of the V oriented downwards
- the notch 260 has the longest branch of its V oriented upwards.
- the elongated body 203 of the key 1 has in its narrowed region 230 a housing 231 which has a profile complementary to the pusher 232.
- the projecting edges 36a and 36b of the plate 35 of the pusher 32 are eliminated in the pusher 232.
- the ribs 238, 239, 258 and 259 extend, in the transverse direction, beyond the edges of the plate 235 to serve as a point of contact with the bottom pins of the rotor.
- FIG. 24 with FIG. 7 A, it can be seen that the central projections 36a and 36b of the pusher 32 are replaced by lateral protuberances 238a, 239a and 238b, 239b at the transverse ends of the ribs of the pusher 232.
- the transverse ends of the ribs define between them a lower longitudinal rib 262a and upper 262b.
- Each pair of ribs on the same face of the pusher 232 define between them a transverse groove 263a and 263b.
- FIG. 25 it can be seen that the bottom pin 518 bears against the upper end 239b of the rib 239 of the pusher 232 and that the lateral pin 219 bears against the top of the notch 241 of this same rib 239.
- the rotor pin located in the housing 122 could be provided to cooperate with the upper transverse end 258b of the rib 258 situated in a parallel plane at the plane of the rib 239.
- the holes 234 in the narrowed area 230 of the key are not shown in FIG. 19, but are visible in FIG. 25.
- FIGS. 26 and 27 represent an alternative embodiment of the pusher of FIGS. 21 to 25.
- the elements of the pusher which are similar to the elements of the pusher 232 bear the same increased reference numbers of 100.
- the pusher 332 differs from the pusher 232 in that the grooves 262a. and 262b of the pusher 232 are replaced by a convex surface 362a, 362b extending between the respective transverse ends of the ribs of the pusher 332.
- the bottom pin 518 is supported on the convex surface 362b of the pusher pusher 332, while the lower convex surface 362a of the pusher 332 bears on the internal cylindrical surface 7a of the stator 7.
- FIGS. 28 to 29 Yet another alternative embodiment of the pusher is illustrated in FIGS. 28 to 29.
- the elements of the pusher which are analogous to the elements of the pusher 232, bear the same reference numbers increased by 200.
- the ribs 438, 439 and 458, 459 of the pusher 432 have a general shape identical to the ribs 138 and 139 of the pusher 132 illustrated in FIG. 8.
- the pusher 432 has at the two transverse ends of its plate 435 projecting edges 436a and 436b which are intended to cooperate respectively with a positioning member and a bottom pin of the rotor.
