Definitions
- the present invention relates to lock cylinders, of the type European or not, composed of a body, forming a stator or not, of a rotor with a key slot and latches, arranged in housings, respectively, the stator and the rotor, each lock being composed of a feeler, with or without intermediate piston, counter piston and spring pushing the counter-piston, the possible piston, and the probe in the direction of the rotor slot.
- the lock receiving housings are distributed in rectilinear rows, comprising 5 to 6 housings having positions different longitudinal lines and the rows are angularly offset around the longitudinal axis of the cylinder, so that the axes of the locks are substantially perpendicular to one of the 4 flat faces of the key, having a flattened rectangular cross section.
- the combination depends on the number of rows of locks, the number of locks per row, position of the locks in a row and of the probe travel in the key, this travel can have from 3 to 6 different levels.
- the document CH 390 178 describes a cylinder in which the lock slots are distributed locally on a propeller fragment, and arranged radially.
- the openings in the flat key are distributed around it and weaken its resistant section less and that, when the key is engaged, each of the feelers comes into contact with friction on a longitudinal area of the key distinct from that of the others feelers, thereby reducing wear.
- the housings distributed in a helix are located in the lower half of the cylinder, which limits the combinatorial possibilities, themselves halved due to the reversibility of the key.
- this fragile key does not limit break-ins with a soft key.
- the object of the present invention is to remedy these disadvantages, providing a cylinder to increase the number combinations, reducing friction wear, improving resistance of the key and increasing the fracturing difficulties.
- the housings formed in the body and the rotor for the locks are distributed over at least three propellers, each making at least one turn in the active part of the cylinder, while the key, on the one hand, has a generally rectangular section which fits in a circle whose diameter is around half the diameter of the rotor and, on the other hand, has protruding at least each of its large faces, at least three longitudinal ribs, some of which are cut by hollows.
- the number of combinations depends on the same parameters as those retained in cylinders with rectilinear rows of locks, but also of new parameters, namely the winding direction of the distribution propellers housings and locks, the starting point of the propellers and the pitch of the propellers, so this number is larger than in a cylinder traditional.
- the ribs combine with the position in space of the locks, on the one hand, to complicate the realization of the hollows, by making this more difficult operation for a burglar, and on the other hand, for oppose any break-in with a soft key.
- the reference numeral 2 designates the envelope of the cylinder composed of a stator 3, a rotor 4 with a slot 5 for the key 1 and of latches 6 arranged in the housings respectively 7 of the stator and 8 of the rotor.
- Each lock is composed of a probe 10, possibly associated with one or more pistons 11, and a counter-piston 12. The pushing spring each lock in the direction of the slot 5 is not shown.
- the housings 7 and 8 formed in the stator 3 and the rotor 4 for the latches 6 are distributed along three propellers, respectively H1, H2, H3 in Figure 1, which here are not the same and have the same direction, but which, in variants, may be of different steps, and of different meanings with intersection on a housing.
- These three propellers, which each make a full turn in the active part of the cylinder, are angularly offset by 120 ° relative to each other, as shown by the letter A, E, I on the Figure 5, but this angular offset may be different.
- the housings 7 and 8 are distributed with a pitch which, here, is constant, but which can to be different.
- the housings 7 and 8 have longitudinal axes which are radial, as shown in Figure 5, by the dashed lines A to L.
- the rotor 4 has three rows of seven housings, while the stator has six rows of seven housing.
- the seventh slot in each row and the three rows additional stator are intended to perform functions complementary such as additional security detection, or participation in a combination modification function.
- the pitch of the housing distribution propellers is chosen by relation to the pitch of the housings 7 and 8 and so that over the length of the useful part of the key 1, the two extreme housings are diametrically opposite, as shown by locks 6a, 6g, but it is obvious that any other distribution can be considered.
- the propellers which, in this embodiment, roll up on the right, can also roll up on the left, or present angular offsets with respect to others, of equal or different values, and have a different starting point on the rotor.
- FIG. 4 shows that the recesses 13, made in the key 1, are conical in shape and correspond to the tip 10a of the probes 10. From in known manner, the length of these probes can take different values. In the case of the cylinder shown, these values are five in number, as shown in T0 to T4 in Figure 4. Each probe size corresponds to a recess 13 whose depth S0 to S4 is adapted. Feelers can also have other shapes: round, square, triangular, oval, rectangular or other.
- Figure 5 which shows the cross section of key 1, puts in evidence that it is part of a rectangle R whose ratio of width R1 on the height R2 is between 3/5 and 9/10 and for example 8/10.
- Figure 6 shows that the cross section of the key fits in a circle 20 whose diameter is of the order of half that of the rotor 4.
- FIG. 5 shows that, in the event that the recess 13 performed in position A is of maximum size S4, the presence in the sections transverse neighbors of hollows 13, also having maximum sizes, as shown for positions E, H and J, the core of the one-section key sufficient to withstand the forces received, i.e. preventing the rupture of that key.
- Figures 7 and 8 show, respectively, a non-key reversible 1a and a reversible key 1b, show that even with recesses 13 of maximum depth, eighteen for Figure 7, and thirty six for FIG. 8, the material constituting the key is little affected and that, by however, the key is very difficult for a locksmith who does not have precise machining means, such as a numerically controlled machine.
- each of the recesses 13 comes into contact with only one or two feelers, which considerably limits the wear of key 1, but also that of feelers, and by reaction, those of housings 7 and 8.
- the cylinder according to the invention allows significantly increase the number of combinations, while improving resistance of the key and reducing the risk of break-ins.
- the axes of the housings 7 and 8 receiving a lock and, which are necessarily coaxial, may, while remaining in a transverse plane of the body and of the rotor, not pass through the axis of rotation of the rotor, either by angular offset, or by transverse offset, either by these two offsets.
- This shift which can concern at least one accommodation per propeller, one propeller or all propellers, further increases the number of combinations but, above all, makes it very difficult the break-in.
