Definitions

  • the invention relates to a permutation lock for suitcases, bags or the like according to the preamble of claim 1.
  • a lock of the type in question is known from US Pat. No. 4,385,509, each number disk forming a star wheel on the end face facing the actuating handle. This works together with a finger of the actuating handle, which is designed as a push button and is sprung in the direction of the lock ceiling. To adjust the key secret, an additional push button must be pressed, which shifts a locking slide in the opening direction. On this provided projections engage in recesses of locking sleeves, which are also on the axis of the number plate. A locking clutch is provided between each locking sleeve and number plate. However, this can be overcome in the blocking position of the locking sleeves by acting on the actuating handle, the number disk being rotated one step further after each acting. By releasing the push button, the locking slide returns to its starting position. Then it is necessary to open the permutation lock to select the newly set key secret.
  • the object of the invention is based, to design a permutation lock of the type in question in a technically simple manner so that despite the small dimensions of the permutation lock, a stable structure is realized, and that an unwanted self-adjustment of the chosen key secret can not occur.
  • a generic permutation lock of increased use value is specified.
  • the adjustment mechanism is stable. Furthermore, no unwanted adjustment of the key secret can take place. Opening the case, bag or the like initially requires the correct key secret to be set. Then the locking sleeves are in such a position in which a locking rocker which interacts with them is released for pivoting and which interacts in a known manner with side locking parts, such as, for example, locking slides. After opening the case, the existing key secret can be adjusted by first carrying out a transverse displacement of the carrier with the axle journals attached to it. The rotary movement of the locking sleeves is blocked by this transverse displacement. However, they are still in mesh with the sprockets of the actuating handle.
  • a mandatory displacement of the carrier in the longitudinal direction is required. Only then can the actuation handles be shifted, taking away the number disks, so that a new key secret can be selected.
  • This is fixed in that the carrier is first shifted longitudinally with the tooth engagement and then moved in the transverse direction while the blocking sleeves are not blocked. So there are two movements running in different directions, which only allow an adjustment of the key secret.
  • the Actuation handles can be designed differently. They can be used, for example, as setting wheels or as push buttons. However, precautions are always taken to ensure that relocation of the actuation buttons causes the sprockets of the actuation handles to be carried along.
  • the locking sleeves are blocked in a simple manner in the event of a transverse displacement by the locking projections projecting radially at the free end of the axle journals, which protrude into form-fitting openings extending from the hub bore. Then the actuating handle can no longer be moved because the gear transmission is blocked. This is only possible after the carrier has been longitudinally displaced. So that the wearer cannot be relocated if the key secret is set incorrectly, a snag occurs between the wearer and the paddle lock of the lock. By choosing the right key secret, however, the rocker seesaw swings into a position that allows the wearer to move in both directions.
  • the slide can be displaced by means of an operating extension protruding outwards through an L-slot in the lock housing.
  • L-shaped slots in permutation locks are known.
  • one leg of the L-slot only serves to secure the shifted position of the operating extension while facilitating handling.
  • the operating extension of the permutation lock according to the invention preferably extends into the inside of the case, so that it cannot be operated from the outside like the push button of the permutation lock according to the prior art mentioned at the beginning.
  • the briefcase illustrated in FIG. 1 has a bottom case 1 forming the bottom of the case and a top case 2 connected to it via hinges (not shown).
  • the latter represents the case lid and is supported in a closing joint 3 on the bottom case 1.
  • the aperture 4 thus forms a lock cover 7 at the level of the permutation lock.
  • the permutation lock 5 and the side locks 6 are located on the long side of the case opposite the hinges (not shown).
  • the centrally arranged permutation lock 5 is overlaid by a pivoting handle 8, which is pivotably mounted on the panel 4 and is pivotally mounted in lugs 9 on the panel side.
  • the aforementioned closures 6 are of identical construction. Each fastener 6 interacts with an actuation button 10 mounted on the case side wall. The latter also extends in the case lower part 1 and is articulated with a transmission lever 11. A spring, not shown, acts on the transmission lever 11 and thus the actuation button 10 in the outward direction. The transmission lever 11 acts together with a locking rod 12 sprung in the direction of the actuation button 10, which in turn has a Lock bar 13 is coupled. From the locking rod 12 a closing part 14 protrudes beyond the closing joint 3, which has a hook-shaped design and interacts with a counter-closing part 15 on the case lid side. The locking bar 13 in turn consists of flat material and forms a fork 16 at the end facing the permutation lock 5. This is preceded by a case position switch S, which only releases a displacement of the locking bar 13 when the case with its lower case part 1 or with its hinge-side case narrow wall on one Contact surface is laid.
  • the permutation lock 5 has a box-shaped lock housing 17, which is composed of a lock base 18, two parallel lock case longitudinal walls 19, 20 and the end walls 21, 22 connecting these.
  • a lock base 18 In the lock case longitudinal walls 19, 20, in the upper area, there are three axes 23 directed transversely to the longitudinal extent of the lock housing 17, which in turn each carry an adjusting wheel 24 adjacent to the lock case longitudinal wall 20.
  • the spherically shaped casing of the adjusting wheel 24 is provided with longitudinal grooves 25 in order to facilitate handling.
  • the area of the setting wheel facing the lock cover 7 penetrates adapted windows 26 of the lock cover 7, cf. in particular FIG in turn bears against the inner surface of the lock case longitudinal wall 20.
  • Both the setting wheel 24, axis 23, ring gear 27 and locking ring 28 are made of the same material.
  • the ring gear 28 is equipped with locking recesses 29.
  • a resilient tongue 30 extending from the lock base 18 engages in one of them in a positive manner.
  • Each axis 23 is also a carrier of a number disc 31, which has a frustoconical shape in cross section.
  • the symbols designed as numbers from 0 to 9 are located on the circumference of the number disk 31.
  • the number disks 31 are supported with their larger cross-sectional end face on the inner surface of the lock case longitudinal wall 19.
  • the locking ring 28 also has ten locking depressions 29.
  • Each toothed ring 27 meshes with the toothing of a locking sleeve 33 arranged on an adjacent axis 32.
  • the toothing of this locking sleeve 33 is also designed to form a toothed ring 33 '.
  • These axes 32 are closer to the lock base 18 than the axes 23 having the setting wheels 24.
  • the three axes 32 are seated on a carrier 34 which is guided in the interior of the lock housing both in the transverse and in the longitudinal direction.
  • Each journal 32 carries one radially at its free end protruding locking projection 35. This can be positively immersed in a radial opening 37 extending from the hub bore 36 of the locking sleeve 33.
  • the support 34 which is supported on the lock base 18 on the one hand, has in its upper, central region a guide pin 38 opposite the axle journal 32, which plunges into a longitudinal slot 39 of the lock case longitudinal wall 19.
  • the rear ring gear 27 and the ring gear 33 'of the locking sleeve 33 have the same number of teeth. In the exemplary embodiment, these are 10 teeth each. One revolution of the number disc 31 therefore corresponds to one revolution the locking sleeve 33, which has a flat 40 beyond its ring gear 33 '.
  • the abovementioned flats 40 of the locking sleeves 33 act together with a longitudinal edge 41 of a locking rocker 42 which is pivotably arranged in the end walls 21.
  • the locking rocker 42 forms bearing journals 43 formed on the end, which plunge into bearing openings 44 in the end walls 21, 22.
  • the bearing openings 44 are located close above the lock base 18 and adjacent to the lock case longitudinal wall 9.
  • the locking rocker 42 forms an upward-facing ledge 45, which forms the longitudinal edge 41.
  • the aforementioned bar engages in the area between the toothed ring 33 'and the facing surface of the carrier 34, cf. in particular FIG support the rocker switch 42.
  • the locking rocker 42 In the direction of the contact position to the locking sleeves 33, the locking rocker 42 is loaded by spring tongues 46.
  • the latter are formed by cut-out areas of the lock base 18.
  • the carrier 34 is also designed so that it hooks on the locking rocker 42 if the key secret is set incorrectly.
  • two hooks 47 extend from the underside of the carrier 34.
  • the hooked heads 48 pointing in the direction of the axle journals 32 lie opposite form-fitting recesses 49 of the locking rocker 42. If the key secret is set correctly, the hook heads 48 do not engage in the cutouts 49, see FIG. 9.
  • the lower edge of the carrier 34 is surmounted by an operating extension 50 which passes through an L-slot 51 of the lock base 18 and projects over it.
  • an operating extension 50 which passes through an L-slot 51 of the lock base 18 and projects over it.
  • the locking rocker 42 with two integrally formed wings 52 with an angular shape in plan, projects beyond the corresponding end walls 21, 22 of the lock housing 17.
  • the wing sections 52 ′, 52 ′′ act together with the fork 16 of the associated locking bar 13.
  • the closed case If the closed case is to be opened, it must be placed on a support surface with its lower case part 1 or with its narrow hinge side. As a result, the case position switch S reaches the locking bars 13 assigned to them in the release position. The correct key secret must then be set using the setting wheels 24. This can be seen on the number disks 31 which also reach through window 26 'of the castle ceiling 7. The sprockets 27 of the setting wheels 24 and sprockets 33 'of the locking sleeves 33 are rotated so that their flats 40 run parallel to the longitudinal edge 41 of the locking rocker 42. This thus pivots into the position according to FIGS. 6 to 11. From FIG.
  • the locking rocker 42 cannot pivot, and when an attempt is made to actuate the locking bars 13, the forks 16 act on the wing legs 52 'of the pivoted locking rocker 42 with their forks 16, see dash-dotted representation in FIG. 7 Thus, the locking parts 14 located on the locking rod 12 cannot get into a release position.
  • the forks 16 remain in their engagement position with the wings 52.
  • the setting wheels 24 are then not rotatable, since the flats 40 of the locking sleeves 33 are supported on the longitudinal edge 41 of the locking rocker 42, which then cannot be pivoted.
  • the key secret can be changed in this position.
  • the operating extension 50 protruding into the inside of the case can be grasped in order to displace the carrier 34 in the transverse direction, see FIG. 13.
  • the rotational movement of the locking sleeves 33 is additionally blocked. This is important if the closure should have entered the locked position despite the lid being open.
  • the operating extension 50 has moved in the L-leg 51 '. It is then at the level of the other L-leg 51 ''.
  • the carrier 34 must then be displaced in the direction of the arrow according to FIG. 14, the operating extension 50 entering the other L-leg 51 ′′, see dash-dot line in FIG. 5.
  • the locking sleeves 33 are taken along via the axle journals 32, the toothed rings 33 'of which disengage from the toothed rings 27 of the setting wheels 24, see FIG. 15.
  • the setting wheels 24 can be rotated. to set another key secret.
  • the symbols recognizable from the window 26 'then indicate the new key secret.
  • This is fixed in that the carrier 34 is moved back in the longitudinal direction to produce the tooth engagement. The transverse displacement is then to be carried out, the locking projections 35 leaving the openings 37 of the locking sleeves 33 assigned to them.
  • the forks 16 of the locking bars 13 are also removed from the wings 52 of the locking rocker 42 with this.
  • the key secret can then be adjusted.
  • the locking rocker 42 pivots, the hook heads 48, the hooks 47 of the carrier 34 engaging with the formations 49 of the locking rocker 42.
  • the permutation cannot then be changed, since the hook engagement prevents both a transverse displacement and a longitudinal displacement of the carrier 34.
  • the correct key secret must therefore always be selected beforehand.
