Definitions

  • the present invention relates to a cylinder lock of the type which allows the insertion and rotation of a key on one side even when a key is inserted on the other side.
  • Locks of the indicated type are described in the following patents: DE-OS 1553535, 3535426, 3828354, DE-AS 1150903, 1194287, 1261010, DE-PS 1930739 and EP-A-264923.
  • a cylinder lock of the indicated type comprises a coupling element which provides the rotational connection between a plug and the bit, regardless of whether a second key is present or not in the lock on the side opposite to the one in which the key is inserted.
  • the aim of the present invention is to provide a coupling element which has a simplified structure and can be assembled more easily than the conventional ones, so that it is more economical to manufacture.
  • a further object of the present invention is to provide a coupling element which is miniaturizable so that it can also be applied to cylinder locks having a small-diameter plug.
  • the reference numeral 1 designates a cylinder lock conventionally composed of two identical parts A and B.
  • the description which follows is given with regard to only one of said parts, and when it is necessary to make a distinction among the elements of one part or the other, the related reference numerals are accompanied by the letter a or b depending on whether the elements belong to part A or respectively to part B.
  • the lock comprises a shell which is composed of two coaxial tubular bodies 2 connected by a bridge-like elongated body 3 having, in a median position, a recess 4 which separates the tubular bodies 2.
  • Two plugs 5 can rotate in the tubular bodies 2 and are axially crossed by the keyway 6 for the insertion of the key 7.
  • the reference numerals 8 and 9 designate the holes for the accommodation of the tumblers composed of the pin-tumblers 10, the counter-pins 11 and the springs 12.
  • the tumblers conventionally prevent the rotation of the plugs when the key is not inserted or allow their rotation when the key is inserted.
  • the bit 14 of the lock is rotatably mounted on the opposite ends of the plugs 5.
  • the bit 14 comprises a ring 15 from which a radial wing 16 extends; said ring being able to pass through the recess 4.
  • the opening 18 is aligned with cylindrical seats 20 which have the same diameter and are defined in the opposite ends of the plugs.
  • the seats 20 also have longitudinal grooves 21 whose cross-section is equal to that of the groove 19.
  • a coupling element is accommodated in the seats 20 and passes through the opening 18.
  • the element 22 is formed by two cylindrical bushes 23 whose length is equal to, or slightly less than, the length of the seats 20 in which they are guided.
  • the bushes 23 are externally provided with an axial tooth 24 which slidingly engages in respective grooves of the seats 20, so that the bushes are rotationally coupled to the plugs but are axially movable in the seats 20.
  • Respective mushroom-like elements 29 are accommodated in the bushes 23 and comprise a cylindrical stem 30 and a circular plate 31.
  • the edge of the circular plates 31 has an L-shaped cross-section so as to form a surface co-planar to the surface of the collars 27.
  • the mushroom-like elements 29 are kept in abutment against the collars 27 by springs 32 which act between the rings 26 and the circular plates 31.
  • the stems 30 of the mushroom-like elements 29 are guided in a tube 33 which passes through the opening 18 of the bit and on which the rings 26 of the two bushes 23 can slide.
  • a spring 34 is arranged in the tube 33 between the stems 30 and, by acting on the mushroom-like elements 29, moves the bushes 23 to a mutual spacing position defined by the abutment of the rings 26 against annular shoulders 35 formed on the outside of the tube 33.
  • the shoulders 35 (which may also be constituted by rings recessed in the tube 33) have such a mutual distance that the coupling element 22 is shorter than the accommodation formed by the seats 20 and by the opening 18 and it can thus perform axial movements which allow the bushes 23, if orientated correctly, to alternately engage the opening 18 and define a rotary coupling with the bit 14 by means of the teeth 24.
  • the described coupling element operates as follows.
  • the key 7 is left inserted in the keyway 6b and a second key is inserted in the plug 5a, initially the key enters the notches 28a of the bush 23a and the circular plate 31a moves in contrast with the return action of the spring 34. Since the spring 32a keeps the collar 27a in abutment against the circular plate 31a, the bush 23a moves toward the bit. If said bit is rotated with respect to the plug, so that the tooth 24a cannot enter the groove 19 of the bit, then if one continues to act on the second key, the circular plate 31a is moved axially within the bush 23a and the spring 32a is compressed, allowing the key to enter the plug 5a completely; said plug can thus be rotated with respect to the bit.
  • the bush 23a too, by being rotationally coupled to the plug 5a, is rotated until the tooth 24a is aligned with the groove 19.
  • the spring 32a having been pre-loaded by the circular plate 31a, pushes the bush 23a into the opening 18 and thus pushes the tooth 24a into the groove 19, providing a rotational coupling which allows the rotation of the bit.
  • the insertion of the bush 23a is accompanied by the simultaneous expulsion of the bush 23b from the bit 14 due to the spring 34, which keeps the bushes 23a, 23b spaced in the position in which the rings 26a and 26b abut against the shoulders 35a and 35b.
  • bit 14 is never free on the plugs but is always rotationally coupled to one of them; since said plugs are locked by the tumblers, they thus offer maximum resistance to effraction attempts performed in the attempt to make the spring-latch or the bolt retract into the lock by rotating only the bit and not the plug.
  • a considerable advantage of the invention resides in the simplified structure of the coupling element 22 which, by constituting a single element, is easy to fit during the assembly of the lock.
