Definitions
- the present invention relates to keys for cylinder locks and relates more particularly to keys of the type comprising at least one movable pusher, movable relative to the key body according to a stroke limited, said pusher being intended to cooperate with a positioning member carried by the barrel rotor so as to protrude from the outer contour of the key and push a movable pin provided in the rotor to a position releasing the rotor from rotation barrel relative to its stator.
- Such a key is for example known from the Patent FR.2 521 201.
- a safety key cylinder for operating a lock of which the elongated key body intended to penetrate into a key housing of a barrel rotor is provided with actuating means intended to cooperate with a positioning for actuating at least one movable pin of the rotor, in a position allowing rotation of the rotor of the barrel relative to the stator thereof.
- Ways actuation of the pin consist of two mounted pushers displaceable in translation each in a hole opening on the one hand into a channel in the key for a fixed positioning rod integral with the stator and on the other hand, on the outer lateral surface of the body of key.
- the key described in patent FR.2 521 201 comprises a housing for the mobile pusher in the plane key body and leading to the two edges of the key body.
- a bleeding necessary for the passage of the organ of protruding positioning inside the housing key is provided in the longitudinal edges of the body of key.
- the invention aims to remedy the drawbacks of this type of key by creating a key which all being provided with movable mechanical means for unlocking a pin of immobilization in rotation of the barrel rotor, present songs likely to receive over their entire surface of the actuation profiles of the pins of the cylinder.
- the key body elongated shape for entering a key housing of the barrel rotor being provided with actuating means intended to cooperate with a positioning member for actuate at least one movable rotor pin in a position allowing rotation of the barrel rotor by compared to the stator thereof, characterized in that the means for actuating the pin consist of at least two pushers mounted movable 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 of 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. 1 is actually a blank flat key whose body 1 has grooves longitudinal 2 separated from each other by ribs 3 and whose edges 4 are flat or slightly domed as shown in Fig.4.
- the body key has profiles on its two large faces defined by grooves and longitudinal ribs 2 and 3 symmetrical about the axis of the key, which makes the key reversible.
- the two branches 7 and 8 define a notch 11 in which is intended to engage a rod 12 shown in phantom in the form of a positioning member for pushers 13, 14 arranged respectively in branches 7 and 8 of the fork 6 and whose role will be clearly explained with reference to Figs. 2 and 3.
- Fig. 2 shows a barrel or cylinder of lock comprising a stator 16 in which is mounted rotation of a rotor 17.
- the rotor 17 has a housing 18 in which the key body 1 is engaged.
- the barrel cut in Fig. 2 is made at right of pushers 13 and 14 housed respectively in the legs 7 and 8 of the fork 6 of the body end key 1.
- the key being fully engaged in the rotor 17, its notch 11 defined by the interval between the branches 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 perpendicular to the housing 18 for the key.
- the pushers 13 and 14 are shaped and identical dimensions. Each pusher has a end portion 22 facing the notch 11 which is ends with a chamfered point 23 intended to cooperate with rod 12 to move the pusher 13 or 14 towards the outside of the outline of the key.
- the pusher also has an intermediate reach 24 thicker and opposite the point 23, one end 25 intended to cooperate with a pin 26 displaceable in translation in a channel 27 formed in the rotor 17 and opening onto the lateral surface of the rotor in look of a pin 28 arranged in a blind hole 29 stator 16 and biased by a spring 30 shown at FIG. 3, which, when the rotor 17 is in the position of closing the lock and the key is removed, requests the pin 28 so that its lateral surface either located on either side of the contact surface between rotor 17 and stator 16 and prevents rotation 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 having a shoulder 32 cooperating with an edge of the seat 24 of the pusher to prevent that the pusher does not escape into the notch 11 of the fork 6 of the key 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 ranges 24 and its end opposite to the shoulder 32 and opening into the side wall outer of each branch 7,8 of the fork, comprises a crimp 34 or any other type of stop cooperating with the end of the scope 24 opposite to that located in look of the shoulder 32 to limit the stroke of the pusher so that only its end 25 can protrude outside the key outline and ensure 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.
- the other pusher 14 is in support with or without play against a full part of the stator 16, while its chamfered tip 23 protrudes from the wall side of the notch 11 and is in contact with or free of play with rod 12 roughly opposite the area of contact between this rod and the tip 23 of the pusher 13.
- the pusher 14 therefore does not intervene in actuation of pins 26 and 28.
- the key according to the invention is reversible and can therefore be introduced interchangeably, so as to involve the pusher 13 or 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 can be housed in the full part of the body 1 located 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 to optimize the grooving the key.
- the key according to the invention is devoid of lateral grooves, and special recesses at the end of key, which allows the possible use of its edges to realize profiles on the whole surface actuating the pins of the barrel.
- the two pushers are mounted each in a branch of a fork, they can retract in the notch 11 of the fork and do not overflow the external dimensions of the key.
- the axes of the pushers 13 and 14 and consequently that of the rod 12 mounted in rotor 17 are offset from the axis from pin 26 towards the end of the key, inside to 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 rod 12 forming positioning member, the pusher in contact with the pin 26, in this case pusher 13, is pushed back towards the interior of its housing 31 formed in the branch 7 of the fork, under the effect of the return spring 30 of the pin 28 in the locked position.
- the key according to the invention has a shape general simple and requires only a layout also very simple rotor to place a rod in it forming positioning member, transverse to the notch at the end of the key.
