Definitions

  • the present invention relates to a combination lock particularly suitable for small-size portable containers, such as bags, handbags and beauty-cases, as well as for cabinets and so on.
  • the bushes and the passing holes of said fixed walls are provided with respective radial complementary projections and recesses, which cause such sliding of the bushes, and therefore the opening of the lock, to be allowed only when all the bushes, by means of the respective wheels, are angularly disposed in such a way that said projections and said recesses are aligned with each other, that is when it is formed the chosen "combination".
  • it can also be made the change of the combination which includes the control of a similar axial sliding of the bushes, in the same sense of that allowing the opening of the bolt but of a greater entity.
  • US-A-3416338 (which represents the prior art part of the claim) discloses, on the other hand, a combination lock, in which the bolt is separated from the bushes and made integral with a sliding frame, from which there extend the walls alternated with the rotating wheels, so that during the bolt opening the above mentioned walls slide with respect to the bushes and not viceversa.
  • the bushes may be caused to slide in opposite sense, on the contrary, for the combination change.
  • the object of the present invention is then to realize a combination lock which is of reduced bulk and also solves any spring problems.
  • a combination lock comprising a bolt resiliently biassed in closed position, a plurality of rotating wheels disposed close to each other and means able to subordinate the movement of the bolt to an open position by the rotation of all the above mentioned wheels to respective prefixed angular positions, said means comprising a plurality of parallel walls alternated to said wheels and extending transversally from a sliding frame rigidly connected to said bolt, a pin passing through aligned holes of said wheels and of said walls and a succession of bushes rotatably and slidingly mounted on said pin and engaged in said holes of respective wheels so as to be connected to them forthe rotation but axially slidable with respect to them, said bushes being biassed in a rest position by at least one first spring, said bushes and said holes of said walls being provided with radial complementary projections and recesses able to allow the mutual sliding of said bushes and said walls only if all the bushes are disposed in a predetermined angular position as a consequence of the rotation of all
  • the combination lock according to the invention therefore maintains the provisions of US-A-3416338 as regards the two movements in opposite senses for the lock opening and the combination change, so that its bulk is advantageously reduced and a square shape, may also be realized for possible use of the lock on beauty-cases or the like. Moreover, any spring problem is solved therein, by employing separate springs for stressing the sliding frame and the succession of bushes in their respective rest positions.
  • FIG. 1 In the drawings is illustrated a combination lock 11, which together with a mask 12 which turns around it (Figs. 1 and 2) realizes a closure particularly suitable for beauty-cases (as well as for other small-size containers like cabinets, bags and handbags).
  • the lock is evidently destined to be fixed to a container base or casing, while the mask is to be fixed to the relative cover or door.
  • the mask 12 is constituted by a fixed part 13, which is provided with a central projection 13 which can be inserted in a corresponding central cavity 15 of the lock for positioning and centering reasons, and by a rotating U-shaped part 16, which is connected to the fixed part 13 by means of a hinge pin 17 and is provided with a control knob 18.
  • the two parallel sides of the rotating part 16 are further provided with two cavities 19 and 20, the second of which is completely open downwards (Fig. 4); the purposes of said cavities will be explained farther on.
  • the lock 11 includes in its turn a parallele- pipedal casing 21, which is closed upwardly by a cover 22 including said cavity 15 and provided with three symmetrical windows 23.
  • a cover 22 including said cavity 15 and provided with three symmetrical windows 23.
  • the mechanism of the lock which includes a horizontal fixed pin 26, on which there are assembled in a rotating and axially sliding way three cylindrical bushes 27 stressed in the rest position illustrated in Figs. 3 and 4 by a spring 28 mounted on the pin 26 and partially inserted in an axial cavity 29 of one of the bushes.
  • every bushes 27 is provided with a radial projection 30, which extends only for a part of the length of the bush.
  • respective parallel wheels 31 every one of which projects outwards the cover 22 through one of the windows 23 and has a central through-hole 32 provided with a circumferential succession of radial notches 33 (Fig. 3) in a selected one of which is slidingly inserted the radial projection 30 of the respective bush for the rotational connection between bush and wheel.
  • Every wheel 31 is further provided outwardly with angular positioning notches 34, with which cooperates a respective folded elastic tab 35 extending from a fixed plate 36 fixed to the bottom of the casing 21 (Figs. 3 and 4).
  • Between the one and the other of said notches 34 there are impressed or cut over every wheel 31 the numbers from 0 to 9 which, visible one at a time from outward, identify in numerical form the angular position assumed each time by the wheel.
  • the opening combination can be changed by disposing all the bushes 27 in the opening position, that is by rotating the wheels 31 until to form the same combination, and then by pushing the pin 50 towards the inside of the casing 21, so as to cause the succession of bushes 27 to axially slide until to release their radial projections 30 from the inner holes of the respective wheels. Then these latter can be rotated independently from the bushes until to choose a different notch 33 to be engaged with the projection 30 of the respective bush, so as to fix a different angular position, that is a different number, which corresponds to the opening angular condition of the bush. When this has been made, the pin 50 is released, repairing the engagement, however modified, between bushes and wheels.
