Definitions

  • the present invention relates to keys for cylinder locks and relates more particularly to keys of the type comprising at least one movable plunger, movable relative to the key body according to a limited stroke, said plunger being intended to cooperate with a positioning member carried by the barrel rotor so as to project relative to the external contour of the key and to push a movable pin provided in the rotor towards a position releasing in rotation the barrel rotor relative to its stator.
  • Such a key is for example known from the FR patent. 2,521,201.
  • the key described in this patent includes a housing for the movable pusher formed in the mean plane of the key body and opening onto the two longitudinal edges of the key body.
  • a groove necessary for the passage of the positioning member which projects inside the key housing is provided in the longitudinal edges of the key body.
  • the invention aims to remedy the drawbacks of this type of key by creating a key which, while being provided with mobile mechanical means for unlocking a pin for immobilizing the barrel rotor in rotation, has edges capable of receiving over their entire length. surface of the actuation profiles of the cylinder pins.
  • a safety barrel key for operating a lock the elongated key body intended to penetrate a key housing of the barrel rotor being provided with actuating means intended to cooperate with a positioning member for actuating at least one movable rotor pin in a position allowing the rotation of the barrel rotor relative to the stator thereof, characterized in that that the means for actuating the pin are constituted by at least two pushers mounted displaceable in translation in at least two branches of an end fork of the key, the interval between the branches of the fork being intended to receive the 'positioning member during the engagement of the key in the barrel rotor to cause the displacement of said pin by one of the pushers.
  • the key shown in Fig.l is in fact a blank flat key whose body 1 has longitudinal grooves 2 separated from each other by ribs 3 and whose edges 4 are flat or slightly curved as shown in Fig .4.
  • the key body has on its two large faces profiles defined by grooves and longitudinal ribs 2 and 3 symmetrical about the axis of the key, which makes the key reversible.
  • a fork 6 is formed, the two branches 7 and 8 of which have beveled ends 9, 10. These ends can take any other suitable form.
  • the two branches 7 and 8 define a notch 11 in which is intended to engage a rod 12 shown in phantom forming a positioning member for pushers 13, 14 disposed respectively in the branches 7 and 8 of the fork 6 and whose the role will be clearly explained with reference to Figs. 2 and 3.
  • Fig.2 shows a barrel or lock cylinder comprising a stator 16 in which is rotatably mounted a rotor 17.
  • the rotor 17 has a housing 18 in which the key body 1 is engaged.
  • the barrel of FIG. 2 is cut in line with the pushers 13 and 14 housed respectively in the branches 7 and 8 of the fork 6 at the end of the key body 1.
  • the key being fully engaged in the rotor 17, its notch 11 defined by the interval between the arms 7 and 8 of the fork, receives the transverse rod 12 forming a positioning member mounted in a bore 20 of the rotor 17 extending perpendicularly to housing 18 for the key.
  • the pushers 13 and 14 are of identical shapes and dimensions. Each pusher has an end portion 22 facing the notch 11 which ends in a chamfered tip 23 intended to cooperate with the rod 12 to ensure the displacement of the pusher 13 or 14 towards the outside of the outline of the key.
  • the pusher further comprises a thicker intermediate surface 24 and opposite the tip 23, one end 25 intended to cooperate with a pin 26 movable in translation in a channel 27 formed in the rotor 17 and opening onto the lateral surface of the rotor opposite a pin 28 disposed in a blind hole 29 of the stator 16 and urged by a spring 30 shown in FIG. 3, which, when the rotor 17 is in the closed position of the lock and the key is withdrawn, urges the pin 28 so that its lateral surface is located on either side of the surface contact between the rotor 17 and the stator 16 and prevents rotation of the rotor.
  • Each pusher 13,14 is housed in a hole 31 opening on the one hand into the notch 11 and on the other hand on the outer surface of the corresponding branch 7,8 of the fork 6 and comprising a shoulder 32 cooperating with an edge of the range 24 of the plunger to prevent the plunger from escaping into the notch 11 of the fork 6 of the key in order to avoid any obstacle to the engagement of the positioning member 12 in the notch 11.
  • each pusher has a section equal to that of the bearing surfaces 24 and its end opposite to the shoulder 32 and opening into the outer side wall of each branch 7,8 of the fork, comprises a crimping 34 or any other type of '' stop cooperating with the end of the bearing surface 24 opposite to that situated opposite the shoulder 32 to limit the stroke of the pusher so that only its end 25 can protrude outside the outline of the key and ensure the actuation of the pin 26 of the rotor 17.
  • Each pusher thus has a translational travel limited by the shoulder 32 and the crimping 34 of the hole 31 in which it is housed.
  • FIG. 2 It can be seen in FIG. 2 that it is the pusher 13 placed in the branch 7 of the fork which is pushed back by the rod 12 of the rotor 17 to ensure the movement of the pins 26 and 28 in positions allowing rotation of the rotor.
  • the other pusher 14 is in abutment with or without play against a solid part of the stator 16, while its chamfered tip 23 projects out of the side wall of the notch 11 and is in contact with or without play with the rod 12 roughly opposite the contact zone between this rod and the tip 23 of the pusher 13.
  • the pusher 14 therefore does not intervene in the actuation of the pins 26 and 28.
  • the rod 12 forming a positioning member disposed in the rotor 17 so as to be engaged in the notch 11 of the key asymmetrically, and is brought closer to the lateral surface of the notch 11 defined by the inner side of the branch 7 while it is spaced from the inner surface of the branch 8 by a distance equal to or greater than the useful stroke of the pusher for actuating the pins 26 and 28 and placing them in the unlocked position in rotation of the rotor 17 relative to stator 16.
  • the key according to the invention is reversible and can therefore be introduced interchangeably, so as to involve the pusher 13 or the pusher 14.
  • the holes 31 for receiving the pushers 13 and 14 are arranged perpendicular to the longitudinal axis of the key, but offset according to the thickness of the key body so as to be able to be arranged in the solid part of the body 1 situated inside the profiles defined by the grooves 2 and the ribs 3 on the large lateral faces of the body 1. This offset is adjustable in order to optimize the grooving of the key.
  • the key according to the invention is devoid of lateral grooves, and special recesses at the end of the key, which allows its edges to be used if necessary to produce actuation profiles on the barrel pins over the entire surface thereof.
  • the two pushers are each mounted in a branch of a fork, they can retract into the notch 11 of the fork and not exceed the external dimensions of the key.
  • the axes of the pushers 13 and 14 and therefore that of the rod 12 mounted in the rotor 17 are offset relative to the axis of the pin 26 towards the end of the key, inside the barrel and towards the inner end of its housing 18, so that when the key is removed, as soon as the pushers leave contact with the rod 12 forming a positioning member, the pushbutton in contact with the pin 26, in this case the pusher 13 is pushed towards the inside of its housing 31 formed in the branch 7 of the fork, under the effect of the spring 30 for returning the pin 28 to the locking position.
  • the key according to the invention has a simple general shape and requires only an equally very simple arrangement of the rotor to place a rod in it. forming a positioning member, transverse to the notch formed at the end of the key.
