Definitions

  • the invention relates to a permutation lock according to the preamble of claim 1.
  • a permutation lock of the aforementioned type is known from US Pat. No. 4,385,509.
  • the actuating handles are shaped into pushbuttons sprung in the direction of the lock cover, from which fingers directed inward from the lock extend.
  • Each finger of a push button works together with a star wheel of a number disk, which in turn is in latching engagement with a spring-loaded locking sleeve.
  • a blocking slide arranged in the lock housing can only be moved if the correct key secret has been set. Then protrusions of the locking slide enter into form-fitting niches of the locking sleeves. In this position of the blocking slide, the key secret can also be adjusted, the number disks being rotated relative to the locking sleeves via the push buttons.
  • the blocking slide is also moved using an opening button that is accessible from the lock ceiling.
  • the adjustment mechanism of such a permutation lock is relatively light and is not suitable for absorbing larger forces without damage.
  • the object of the invention is therefore to design a generic permutation lock to be stable in use in a technically simple manner in such a way that, in addition to facilitating operation, larger loads can be absorbed without damage despite the small design.
  • a permutation lock of the type in question is created, which is characterized by an increased use value.
  • the actuating handle is designed as an adjusting wheel and sits on the number plate axis. Rotation of the setting wheel accordingly leads to the number plate itself being taken along.
  • the coupling between the number plate and setting wheel can be selected to be stable. Then they can be designed as a separate component, so that different materials can be used. Color matching can also be easily created.
  • the rotary displacement of the setting wheel is transmitted via a rear sprocket to the locking sleeve arranged on the adjacent axis.
  • the axis of the setting wheel, opposite the ring gear forms a locking ring.
  • the locking ring in turn interacts with a resilient tongue of the lock base, the tip of which tongue engages in locking recesses designed by the locking ring. If material with resilient properties is selected for the lock housing, this resilient tongue can be designed with the same material as the bottom of the lock. For example, appropriate plastic can be selected for the lock housing.
  • 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 closure 6 acts together 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 interacts with a locking rod 12 which is sprung in the direction of the actuation button 10 and which is in turn coupled to a locking rod 13.
  • 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 shift of the locking bar 13 when the case with its lower case part 1 is placed on a support surface.
  • 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. 1.
  • 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 form-fitting manner.
  • Each axis 23 is also a carrier of a number plate 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 ring gear 27 meshes with the toothing of a locking sleeve 33 arranged on an adjacent axis 32.
  • the toothing of this locking sleeve 33 is designed to form a ring gear 33 '.
  • These axes 32 are closer to the lock base 18 than the axes 23 which have 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 plate 31 therefore also corresponds to one revolution of the locking sleeve 33, which has a flattened portion 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 45 engages in the area between the ring gear 33 'and the facing surface of the carrier 34, cf. in particular Fig. 8.
  • the locking sleeves 33 experience their axial positional security in that they are on the one hand on the adjusting wheels 24 and on the other hand on the bar 45 support the locking rocker 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 rocker switch 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 protrudes with two integrally formed, 52 angularly shaped wings 52 in plan, the corresponding end walls 21, 22 of the lock housing 17.
  • the wing portions 52 ', 52' act together with the fork 16 of the associated locking bar 13th
  • 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 is visible on the window 26 'of the castle ceiling 7 penetrating number disks 31. About 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 shown in FIGS. 6 to 11. From Fig.
  • 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 axle journals 32 are taken along, their locking projections 35 into the openings assigned to them Immerse 37 of the hub bores 36 in a form-fitting manner.
  • 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 the dash-dot line in FIG. 5.
  • the locking sleeves 33 are taken along via the axle journals 32, the latter Sprockets 33 'disengage from the sprockets 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 with this from the wings 52 of the locking rocker 42.
  • the key secret can then be adjusted.
  • the locking rocker 42 pivots, the hook heads 48 of the hooks 47 of the carrier 34 engaging in the formations 49 of the locking rocker 42.
  • the permutation cannot then be changed, since the hook engagement both a transverse displacement and a longitudinal displacement of the Carrier 34 prevented.
  • the correct key secret must therefore always be selected beforehand.
