Abstract
Description
- The present invention relates t.o 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.
- There are already known combination locks for suitcases of various shape and size, in which a bolt elastically stressed in closed position is locked in such position or let free to move back in open position, un der the control of a suitable knob, according to the angular positions of two or more numbered wheels dispo sed adjacent to one ancther.
- Particularly it is very used a kind of lock, invented by the same Applicant of the present application, in which the opening movement of the bolt is dependent on a corresponding axial sliding of a succession of bu shes connected for the rotation, but not for the axial sliding, to said wheels (a bush for every wheel) and rotatably and slidingly mounted on a pin passing throu gh aligned holes of said wheels and of fixed walls alternated to said wheels. The bushes and the passing ho les 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 wheals are angularly disposed in such a way that said projections and said reces ses are aligned with each other that is when it is formed the chosen "combination". In the same angular conditions it can also be made the change of the combi nation, 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. With such a sliding it is released the rotational connection between bushes and wheels, which is otherwise assured by the engagement of said projections of the bushes in the one or the other of a circumferential succession of radial notches of the inner hole of the respective wheels. These latter can thus be rotated independently from the bushes, so as to modify the re spective angular positions which correspond to the ope ning angular condition of the bushes, that is the respective numerals of the opening combination of the lock.
- The locks of this kind, certainly valid for many ap plications, tend themselves badly to those uses in which the reduced bulk constitutes a merit that cannot be renounced, as for example in bags, handbags, beauty-cases and other small-size containers, such as cabi nets.
- In fact in such locks it is practically impossible to contain the bulk within narrow limits, being necessary to provide in their inside a free space sufficient to allow not only the opening movement of the bolt but also the more extensive movement of combination change. Such a free space is evidently cause of bulk per se, and at the same time is also cause of an asymmetric di sposit ion of the wheels , which is compensated by correspondingly extending the look at the opposite part with consequent further increase in size. furthermore it is clear that the elastic react ion to the extensive movement of the combination change must be assured by a spring of suitable length. which is in its turn cause of bulk. If then, for exampLe for a beauty-case, one wants that the usual rectangular lock becomes squa re, so as to operate with a rotating mask which can be positioned around it, this could be obtained only by increasing the width of the lock until it becomes equal t.o the length, and therefore increasing the lock size: the result would be really very bad from both the aesthetic and economic point of view.
- The object of the present invention is then to realize a combination lock, which is of reduced bulk and for this reason can be realized not only of rectangular shape but also of square shape.
- According to the invention such an object is reached by a lock comprising a bolt elastically stressed in closed position, a plurality of rotating wheels di sposed next to each other and means able to subordina te the movement of the bolt to an open position to the rotation of all the above mentioned wheels to respecti ve prefixed angular positions. said means comprising a plurality of parallel walls alternated to said wheels, 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 for the rotation but axially sliding with respect to them. 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 dispo sed in a predetermined angular position as a consequen ce of the rotation of all the wheels to said prefixed angular positions, characterized in that said parallel walls extend transversally from a sliding frame rigi- dly connected to said bolt.
- The lock according to the invention is therefore of the same kind of the previously described known bolt, but, unlike it, has the bolt integral with the walls atternated with the rotating wheets, so that during the bolt opening the above mentioned walls stide with respect to the bushes and not viceversa. The sliding of the bushes in opposite sense with respect to the movement of the walls, on the contrary can be controlled for the combination change.
- Therefore there are no more two movements of different entity in one sense, but two movements in opposite senses, whose stroke can be opportunely Limited. Consequently the space to be left available for the exe cut ion of such movements can be reduced to minimum, so as to make possible a more contained bulk. In such sense a valid contribution is given by the fact that, the stroke being reduced, shorter springs can be used and, being reduced the free space for such strokes, the a-symmetricity of the bushes and thus the greatest lenght requested for compensating the same are also reduced.
- The bulk being reduced, the lock according to the invention evidently lends it-self very well I also for u - ses rejected unti now to the old kind locks, therein comprised that of a square (or approximately square ) lock.
- The features of the present invention will be better comprised through the following detailed description of an embodiment illustrated by way of non-limita tive example in the enclosed drawings, in which:
- Fig. 1 shows in top plan view a lock according to the invention combined with a mask of approximately square shape to realize a closure particularly suitable for beauty-cases;
- Fig. 2 shows separately in perspective view said lock and said mask;
- Fig. 3 shows the assembly of said lock and said mask in section along line III-III of Fig. I;
- Fig. 4 shows the assembly of said lock and said mask in section allong line IV-IV of Fig. 1, as well as along Line IV-IV of Fig. 5;
- Fig. 5 shows the only Lock in section along line V-V of Fig. 4;
- Fig. 6 shows said lock in section along line VI-VI of Fig. 5;
- Fig. 7 shows said Lock in section along line VII-VII of Fig. 5.
- In drawings is illustrated a
combination lock 11, which together with amask 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 afixed part 13, which is provided with acentral projection 13 which can be inserted in a correspondingcentral cavity 15 of the lock for positioning and centering reasons, and by a rotatingU-shaped part 16, which is connected to thefixed part 13 by means of ahinge pin 17 and is provided with acontrol knob 18. The two parallel sides of the rotatingpart 16 are further provided with twoca vities - The
lock 11 includes in its turn aparallelepipedal casing 21, which is closed upwardly by acover 22 including saidcavity 15 and provided with threesymmetri cal windows 23. Around thecasing 21 under thecover 22. there is disposed and fixed aflat rib 24, which to gether with alower step 25 of thecover 22 operates as support base for therotating part 16 of the movable mask 12 (Figg. 3 and 4) when this one is in a closed position; thefixed part 13 on the contrary abuts behind the assembly constituted by thecover 22 and theflat rib 24, with the projection inserted in the cavity 15 (Figs. 1 and 3). - Inside the
casing 21 is situated the mechanism of the lock, which includes a horizontal fixedpin 26, on which there are assembled in a rotating and axially sliding way three citindrical Ibushes 27 stressed in the rest position illustrated in Figs. 3 and 4 by aspring 28 mounted on thepin 26 and partially inserted in anaxial cavity 29 of one of the bushes. - As it is clearly evident in Figs. 3, 5 and 6, every
bushes 27 is provided with aradial projection 30, which extends only for a part of the lenght of the bush. At such radial projections there are mounted on thebushes 27 respectiveparallel wheels 31 , everyone of which projects outwards thecover 22 through one of thewindows 23 and has a central through-hole 32 provi ded with a circumferential succession of radial notches 33 (Fig. 3) in a selected one of which is slidingly in serted theradial projection 30 of the respective bush for the rotational connection between bush and wheel. Everywheel 31 is further provided outwardly with angular positioning notches 34, with which cooperates a respective foldedelastic tab 35 extending from afixed plate 36 fixed to the bottom of the casing 21 (Figs. and 4). Between the one and the other of saidnotches 34 there are impressed or cut over everywheel 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. - With the three
wheels 31 are alternated the same number ofparallel wails 37, everyone of which is provided with a cilindricalcentral hole 38 aligned with theholes 32 of thewheels 31 and provided with aradial recess 39 complementary with theradial projection 30 of the bushes 27 (Fig. 6). Saidwalls 37 together with a furtherparallel wall 40 provided with a perfec tly cilindrical hole 41 (that is without recess 39), extend from a slidingframe 42. which is situated on the top of thecasing 21 and form a single piece with abeveled tip bolt 43 coming out from thecasing 21 and from theoverlying cover 22 through alignedcavities rib 24 out side the casing 21 (from which they come out throughholes 47. Figs. and 7) stress theframe 42 and there fore thebolt 43 in the position of Figs. 4 and 5, in which, with themovable mask 12 in closed position, thebolt 43 engages in the cavity 19 (beveled too) of therotating part 16 of the mask (Fig. 4). - Through aligned
windows casing 21 on the contrary comes out outside the same casing and the cover 23 apin 50, which has itsinner part 51 abuted against the end of the nearest bush 27 (Figs. 4, 5 and 7) and itsouter part 52 situated, with themask 12 in closed position, in thecavity 20 of therotating part 16 of the mask (Fig. 4). - From the described structure derives the following working of the lock illustrated in the drawings and, mo re generally, of the one according to the invention.
- In the condition illustrated in Fig. 5, all the
bushes 27 have theirradial projections 30 aligned with thecomplementary recesses 39 of thewalls 37. Such common angular condition of thebushes 27, obtainable by forming through thewheels 31 the preselected "combination". al lows thebolt 43 to go back with the f ra- me 42 and thewalls 37 when so stressed by the lower beveling of thecavity 19 of the rotaling wall of the mask. to allow the release of themask 12 from the lock 1 1 for the container opening. Just after, thebolt 43 is stressed by thesprings 46 to return in the star ting position, from which it is for the moment still removed, by making use of its upper beveled part, during the closing of themask 12. - On the contrary if even one of the
bushes 27 were disposed in a different angular position as a result of the missed formation of the prefixed numerical combination. theradial projection 30 of that bush would abut against theadjacent wall 37 and would prevent the slidingframe 42 and therefore thebolt 43 from coming back to the open position. Because of the engagement between thebolt 43 and thecavity 19 of themask 12, this latter would thus remain locked in closed position. - On the other hand the opening combination can be changed by disposing all the
bushes 27 in the opening position, that is by rotating thewheels 31 until to form the same combination, and then by pushing thepin 50 towards the inside of thecasing 21, so as to cause the succession ofbushes 27 to axially slide until l to release theirradial projections 30 from the inner holes of the respective wheels . Then these latter can be rotated independently from the bushes unt i l to choo se adifferent notch 33 to be engaged with theproject ion 30 of the respective bush. so as to fix a different angular position, that is a different number, which cor responds to the opening angular condition of the bush. When this has been made, thepin 50 is released, repairing the engagement, however modified, between bushes and wheels. - As it can be detected from F ig. 5, the movements to which the
sliding frame 42 and the succession ofbu shes 27 must be subjected, in opposite senses, for the opening movement of the bolt and. respectively, for the combination change, are very limited, as well as it is limited the space to be left free to allow such movements. Thesame springs wheels 31.
