Definitions

  • the present invention relates to a safety barrel intended to be operated by a key, for example for driving the movable members of a lock.
  • the invention also relates to the key corresponding to this barrel and the assembly consisting of the barrel and the key associated therewith.
  • a safety barrel is made up of a stator, inside which can rotate a rotor operated by a key; the key is engaged in a key housing made longitudinally in the rotor; to block the rotation of the rotor relative to the stator in the absence of the correct key, a plurality of keying members is used.
  • a locking member consists of a rotor pin and a stator pin placed inside the same bore, the stator pin being pushed by a spring in the direction of the 'rotor axis; when the key is in position in its housing, the active edge of the key, which has teeth, positions each rotor pin so that the interface (rotor pin / stator pin) is exactly at the level of the interface (rotor / stator) and, under these conditions, the rotor can rotate relative to the stator. It can be seen that, in such a device, it is necessary for the rotor pins to protrude from the key housing in order to cooperate with the active edge of the key.
  • this arrangement allows break-in specialists to rotate the rotor by means of a simple tool, generally called a "hook".
  • a torque is exerted on the rotor which causes the rotor to be locked by that of the pins which has the least play in its housing; at this time, by pulling the hook over the entire length of the rotor, one successively pushes all the pins and, in particular, the one which ensured the blocking (rotor / stator): at this moment, the rotor turns at a slight angle which causes it to be locked by another pin, as long as the torque is maintained using the hook.
  • a specialist can, after n longitudinal displacements of the hook, rotate the rotor of a barrel comprising n locking members.
  • the object of the present invention is to describe a security barrel and the corresponding key capable, despite its simplicity of construction, of making any break-in by means of a hook very difficult, if not impossible.
  • a safety barrel is proposed in which the elastically pushed keying member passes through the entire key housing until it is in abutment against a longitudinal rib provided in said housing; the keying member penetrates, through a relief, in the rib, and a residual space is formed between said rib and the wall of the key housing which faces it.
  • the key comprises, at the rib of the barrel, a groove of corresponding profile and can therefore be engaged in the key housing.
  • the end of the key is cut at a bevel, so that the bottom of the groove forms, at the end of the key, a first ramp which, in the residual space, presses on the keying member to obtain the relief of the relief outside the rib during the insertion of the key; when this clearance is achieved, the toothing of the active edge of the key cooperates, by a second ramp, with the relief of the keying member, which allows the subsequent insertion of the key to the member of following keying, with which the same operating mode is achieved.
  • the presence of this double ramp at the end of the key therefore allows the maneuvering of the keying member while the relief carried by it is not directly accessible by the action of a hook.
  • the key may comprise, between the aforementioned groove and the active edge, other grooves and ribs, of so that the second hook could very well not even be capable of pushing the relief of the keying member to the position, which ensures the release of the rotor relative to the stator.
  • this device despite its simplicity, gives the barrel a high degree of security.
  • FR-A-2 565 281 has already proposed a key for a safety barrel comprising an operating element linked to an elongated key body having a rectilinear longitudinal axis, through which the median longitudinal plane P1 of said body passes.
  • key said key body being intended to be inserted into a key housing of said barrel and being entirely comprised between, on the one hand, two lateral planes P3, P4, parallel to the longitudinal plane P1, and, on the other hand, two longitudinal edges disposed between the two aforementioned lateral planes, one of these edges constituting the back of the key body and the other constituting an active edge intended to cooperate with means for keying said safety barrel, the back and the active edge being interconnected by a profile comprising, in the vicinity of the back, a longitudinal groove, the bottom of which is a wall zone having, parallel to the longitudinal axis of the key body, a mean longitudinal plane P2, the line of the active border, which is equidistant from the two edges laterally delimiting said active border, being in a plane P
  • the key according to the invention is characterized in that the free end zone of the key body comprises a first ramp, defined at the end of the wall zone of the profile which delimits the groove, and a second ramp, defined at the end of the active edge, the second ramp being set back relative to the first ramp, in the direction of driving the key into the key housing of the barrel, the two ramps forming acute angles with the longitudinal axis of the key body.
  • the free end zone of the key body is shaped as a point, a vertex thus being defined at one end of the first ramp; provision may be made for the top forming the end of the key body to be arranged at the middle part of the bottom of the groove.
  • the median longitudinal plane P1 of the key body and the mean longitudinal plane P5 of the active edge are substantially combined. It is preferred that the free end of the active border intersects the first ramp along an edge, the midpoint of which is at a distance from the longitudinal center line of the back of the key less than that existing between said line and the face of the so-called wall.
  • the angle formed with the axis of the key body by the first ramp is greater than that formed with said axis by the second ramp, which makes it possible to ensure the relief of the relief of the keying member by a shorter stroke of the key in its housing and, therefore, to shorten the total length of the key.
  • the present invention also relates to a safety barrel intended to cooperate with a key as defined above, said barrel comprising a cylindrical rotor capable of turning in a stator, a key housing being formed longitudinally in the rotor, organs being keyed in the assembly (rotor / stator) and being resiliently pushed into the keying position in the absence of a key in the key housing, unclogging only occurs if the appropriate key is placed in said housing key, each keying member being able to move in translation along a rectilinear axis, a longitudinal rib projecting laterally in the key housing, a residual space being formed between said rib and the opposite face of said key housing, characterized by fact that in the absence of a key, each elastically pushed keying member passes through the key housing until it comes to an end e against said rib, the keying member comprising a relief which, when the keying member abuts against the rib, enters a recess provided for this purpose in said rib, the residual space allowing act
  • the keying member consists of a rotor pin and a stator pin, arranged in the same bore, the stator pin being pushed by a spring, the rotor pin s' pressing, by one of its bases, on the stator pin and carrying, on its other base, the relief which is intended to engage in the rib; it can be provided that the relief is a hemispherical stud arranged along the axis of the rotor pin which carries it and that the rotor and stator pins are cylindrical, the axis of the bore being perpendicular to the axis of the rotor .
  • the key housing has a median longitudinal plane, which passes through the axis of the rotor, the face of the rib on which a rotor pin can bear, being perpendicular to said longitudinal median plane of the key housing.
  • the present invention finally relates to an assembly consisting of a barrel as defined above and a key as defined above, characterized in that the first ramp of the key acts on the locking member, in the residual space provided for this purpose, the obliquity of said ramp being such that the relief of the keying member is released from its recess when the second ramp comes into contact with said relief.
  • each locking member of which consists of a rotor pin and a stator pin
  • the relief is supported on the active edge of the key, the design of said active edge being such that, in the position of maximum insertion of the key into its housing, the interface (rotor pin / stator pin) is brought to the interface (rotor / stator) level.
  • the barrel rotor according to the invention has been designated by 1 and by 2 the stator in which said rotor pivots.
  • the stator 2 has, in its lower part, an extension 3, where the stator pins 4 and their associated springs are partially housed 5.
  • the extension 3 constitutes the lower part of the barrel.
  • Each locking member of the barrel according to the invention consists of the assembly of a rotor pin 6 and a stator pin 4, arranged inside the same cylindrical bore 16.
  • the rotor comprises a housing key 7, arranged longitudinally in an axial plane of the rotor. Inside this key housing protrudes a longitudinal rib 8; a residual space 9 is provided between the rib 8 and the flat face 7 has the keyway, which makes it vis-à-vis.
  • This barrel comprises a plurality of parallel keying members, the axes of which are arranged along the axial plane of symmetry Q of the barrel.
  • the key housing 7 has a profile which corresponds to that of the associated key designated by 10 as a whole; this profile comprises, on the face of the key housing which extends the flat part 7 a , two ribs 7 b , 7 c and, on the opposite face, two ribs 8 b , 8 c , offset in height with respect to the preceding ones, by so that the cross section of the key housing has, below the rib 8, a sinuous shape.
  • the key 10 has, of course, a general profile complementary to that of the key housing 7.
  • the key 10 comprises a groove with a complementary profile 11; in return for the ribs 7 b and 7 c , there are grooves 12 b and 12 c ; in return for the ribs 8 b and 8 c , there are grooves 13 b and 13 c .
  • the key 10 is between two lateral planes P3 and P4 and it is delimited by two transverse edges: the upper edge 14 constitutes the back of the key and is slightly rounded to adapt to the shape of the interface (rotor / stator ), the back of the key coming from said interface when the key is placed in its housing; the border opposite the back of the key has been designated by 15 and constitutes the active border of the key, that is to say that which carries the teeth intended to cooperate with the keying members to ensure their proper positioning in order to release the rotor relative to the stator.
  • the bottom of the groove 11 is constituted by a flat wall, the mean longitudinal plane of which has been designated by P2.
  • the active border 15 of the key is delimited laterally between two edges and the average line equidistant from these two edges is in a plane P5.
  • the plane P5 is offset transversely with respect to the plane P2.
  • the entire key body has a median longitudinal plane P1, which is substantially coincident with P5.
  • the groove 11 is therefore delimited by a bottom 11 a , having the median longitudinal plane the plane P2, by an upper border 11 b , which defines the key back 14, and by a border lower 11 c , which extends transversely to join the sinuous profile of the key, which, downwards, leads to the active border 15.
  • the pins 4 and 6 move in cylindrical bores 16, which open at right angles to the rib 8. According to the axis of the bores 16, a drilling 17 has been made, with a smaller diameter than that of the bores, this drilling passing through right through the rib 8.
  • the spring 5 pushes the pin 6 against the opposite face of the rib 8, said face being perpendicular to the median longitudinal plane of the key housing.
  • the hemispherical stud 18 has the same axis as the rotor pin 6 and therefore constitutes a relief, which can penetrate into the recess formed by the hole 17.
  • the free end of the key body is shaped like a point.
  • the top 19 of the key is located at the central area of the bottom 11a of the groove 11.
  • the tip end is delimited, towards the back of the key, by a bevel 20 and in the opposite direction, two ramps: one, arranged in line with the bottom 11 a of the groove 11, has been designated by 21; the other, constituting the end of the active border 15 of the key, has been designated by 22.
  • the first ramp 21 has the same inclination as the bevel 20, relative to the longitudinal axis of the key 10, and the second ramp 22 has a lower inclination.
  • the ramp 22 intersects the plane of the ramp 21 in an area located in the thickness of the wall 11 c , along an edge 23.
  • the stud 18 then comes in contact with the ramp 22 and a subsequent depression of the key causes the rotor pin 6 to descend due to the support of the stud 18 on the inclined ramp 22 then on the active edge 15 of the key, which follows the ramp 22. It can therefore be seen that, in this way, although, in the rest position, the stud 18 is in the thickness of the rib 8, it is possible, with this key, to attack the stud 18 by the edge active of the key due to a prior action of the ramp 21 in the residual space 9. The descent of the rotor pin under the action of the ramp 21 must be sufficient to ensure the escape of the stud 18 from the drilling 17.
  • breaking in with a hook is practically impossible; one can put in place a first hook in the residual space 9 and press the rotor pin 6 to the upper level of the rib 7 b ; after which it is necessary to set up another hook to come to press on the nipple 18 but, in any case, this other hook cannot descend lower than the rib 7 c ; and, of course, this operation should be repeated for all the other keying members. We see that the break-in is thus made practically impossible.
