Definitions

  • the present invention relates to the field of cylinder safety locks.
  • Such locks comprise a cylinder or core revolving around its own axis inside a cylindrical chamber made in a body of the lock.
  • Integral with the cylinder is a sprocket wheel or another means for operating a closing latch, which is moved between the opened and closed position by means of the rotation of the cylinder. This in turn is determined by a key inserted into an appropriate chamber in the cylinder.
  • a piston or so-called neutral block corresponds to each locking piston, which is also called the end piston.
  • the two pistons are usually in contact with each other and arranged along a radial axis which is the same as the cylinder axis.
  • the neutral pistons are of the same length while the end pistons are of different lengths.
  • the particular extension and arrangement of the end pistons makes up one of the characteristics of the lock (numeration).
  • a flat key provided with a particular profile on one longitudinal side is provided for operating the lock; the profile comprises areas of greater and lesser depth according to the numeration, which are connected by sloping ramps.
  • the key with the numeration corresponding to that of the lock When the key with the numeration corresponding to that of the lock is inserted into the appropriate chamber, it presses the end pistons radially toward the outside for a precise length, determined by the profile of the key and the height of the pistons, in such a way as to push the neutral pistons back into the body, while the end pistons are held back in the cylinder.
  • the contact surface between the neutral blocks and the end pistons belongs to the cylindrical contact surface between the body and the cylinder. It is then possible to rotate the cylinder in the body to effect opening and closing. Any other key profile would push the end pistons for a shorter or longer length than necessary, so that the neutral and/or the end pistons would extend between the body and the cylinder and lock the rotation of the latter.
  • the corresponding keys have indentations of different depths on different faces which oppose the series of pistons.
  • the aim of this application is to realize a lock with a high degree of safety, which permits a large number of numerations and still has relatively moderate size and reasonable production costs.
  • the lock comprises a body, a revolving cylinder in an appropriate seat in the body, a series of pairs of pistons spring driven into notches in the cylinder and body, and at least one or preferably two series of additional pistons, free to slide radially in additional housings made in the cylinder, or collaborating with particular shapings in the body wall.
  • the new lock has a high degree of safety, allows a large number of combinations and can be produced with reduced overall dimensions and at a moderate cost.
  • number 10 shows the lock as a whole. It comprises a body 12, which forms an inner cylindrical slot 14, which receives a cylinder or drum 16 in a revolving manner. It should be noted that in the double lock illustrated in figure 1 and operable from its two ends, there are two consecutive bodies 12 with aligned seats 14 and revolving cylinders 16; a sprocket wheel 18 for operating the latch 20 is respectively integral with the rotation with each cylinder and sliding axially on it.
  • the elements of the right-hand part of the lock are a mirror image of those of the left-hand part in figure 1 and have the same reference numbers; the left part of the lock will be described below, and it should be understood that what is said about it holds good for the right part also.
  • the body 12 has an elongated part provided with holes or housings 22, usually arranged with their axes coplanar. Consecutively to each hole 22, the cylinder 16 has a hole 23; each hole receives a cap 24, a spring 25, a neutral piston 26 and an end piston 28.
  • the axial dimensions (lengths) of the end pistons 28 are different from each other and different in different locks, thus making up a first type of numeration.
  • each hole 23 is in communication with a chamber 30 for the key, substantially extending on an axial plane along the length of the whole cylinder.
  • additional holes or auxiliary housings 32 are foreseen, arranged at an angle with respect to the holes 23 and in communication with the chamber 30.
  • each series comprises holes 32 which have coplanar axes and lie on a plane at an angle with respect to the plane defined by the axes of the holes 23.
  • the axes of two holes 32 are coplanar to the axis of the hole 23 and at an angle of usually 90° to it.
  • Each secondary piston 34 preferably has a head 34' widened at its outer end, having a rounded outer surface collaborating with a widened part 32' of the hole 32.
  • the secondary pistons can be foreseen in different sizes, so as to project into the chamber 30 in a different way.
  • the body 12 has notches or grooves 36 in its inner wall, in a position corresponding to the position of the holes 32, when the hole 23 is aligned with the housing 22.
  • the walls of the notches 36 have a sloping shape, usually without sharp rises, to ease the sliding of the heads 34' when they enter and leave the notches.
  • Each neutral piston 26 has an end part 26' with a diameter suitable for entering the widened part 32' of the hole 32 (in the figures the diameter of 26' is smaller than the diameter 26; it could however also be equal or bigger, as long as it is correlated to the diameter of 32').
  • the lock can be completed with hardened steel pins 40 and 42 in the cylinder and in the body, in one of their zones near the outside, as is already known, to make any break-in with a drill difficult if not impossible.
  • a key for the lock described is shown with number 50 and illustrated in figures 7 and 8. It comprises a shank 52, usually grooved longitudinally in a way already known (in this case the chamber 30 has a corresponding shape). Then on one side it has a succession of points and indentations, which make up a first numeration 54 corresponding to the arrangement of the end pistons 28, and two successions of notches respectively 56 and 58 on two opposite sides, making up two further numerations, which can be varied in each lock and its relative key.
  • the piston 26 is located in an intermediate position between the housing 22 and the hole 23 (or between the body 12 and the cylinder 16) so as to lock any rotation of the cylinder 16 with respect to the body 12.
