Definitions

  • the invention relates to a permutation lock according to the preamble of claim 1.
  • a permutation lock of the type in question is known from DE-A-3 246 272, the compression spring-loaded, frame-shaped window sash having rungs in the form of material-uniform transverse webs which interact with flattening of the locking sleeves.
  • the operating handle can be moved in the opening direction with the help of the window sash, the rungs of which face the flattened locking sleeves.
  • the dragging of the window slide by means of the operating handle takes place via the one fork leg of a spring-loaded shoe.
  • the shoe is moved downwards by control cams, the leg of the shoe releasing the spring-loaded window squeegee for displacement.
  • the operating handle can still be relocated, part of which acts on the control surface of a lever.
  • the latter pivots and kicks against the heart-shaped control curve while rotating the number plate, including the locking sleeves coupled with it. This is made possible because the spring tongues, which have been dragged in the direction of displacement of the operating handle, have come into a release position to the number disks by driving under projections on the housing side.
  • a permutation lock is known from US-A-4 905 488, in which the number disks are in meshing engagement with toothed wheels, which in turn are equipped with heart-shaped control cams.
  • Each control cam works together with an angle lever which, after the gear wheel has been released, rotates it via the control cam into a specific position.
  • the object of the invention is to provide a permutation lock of the type in question with a simple structure of increased security value.
  • the displacement of the window slide is used to move a slide transversely to the plane of movement of the window slide via a corresponding coupling engagement, the latter causing the spring tongues to be released.
  • the slide can then be used to apply a lever that moves against the control cam during its transverse movement, the lever turning the number discs back into a neutral position. If only the release of the spring tongues is brought about by the slide, rod-shaped spring elements bring the control cam back into the neutral position.
  • the corresponding rod-shaped spring elements are anchored in the lock case base and are supported on the heart base of the heart-shaped heart opposite the tip of the heart Control curve.
  • a coupling in the manner of a pin / slot control is provided between the window slide and the aforementioned slide, with an idle stroke lying at the beginning of the movement. The window sash can therefore move in the initial phase of its displacement by a certain amount corresponding to the idle stroke, without the number disks being released.
  • a key secret readjustment device which is locked in the open position of the operating handle by closing the passage of the adjusting lever by means of a projection of the window slide. Therefore, even if the permutation lock is in the open position, the key secret can only be reset if one knows the key secret previously set. A change in the key secret therefore requires that the closed position of the permutation lock be brought about when the container is open. Then turn the number disks according to the key secret set. Subsequently, the locking sleeves can be displaced by means of the adjusting lever, the flats passing through the middle folding bridge-like rungs and the locking sleeves disengaging from the number disks. Then twisting them towards the new key secret respectively.
  • the permutation lock according to the invention can be used favorably in the furniture sector.
  • a handlebar is pivoted via a coupling projection which pivots an angle lever.
  • This is equipped with a support pin to control the central locking rod.
  • the central locking rod is moved into one or the other position.
  • Doors equipped with an espagnolette lock can also be coupled with the window slide.
  • a coupling projection of the window slide acts via a link on a control lever which causes the locking of the espagnolette lock.
  • the control lever is pivoted into one or the other position, taking the rotary rod of the rotary rod lock with it.
  • Sliding doors can also be equipped with the permutation lock.
  • the coupling projection of the window slide acts on the locking hook of the sliding door lock via a handlebar.
  • the locking hook is pivoted.
  • the window slide can then be designed in such a way that it forms a bolt tail protruding into the espagnolette lock. This is attacked by a rotary nut which represents the operating handle.
  • the permutation lock is then actuated by turning the operating handle.
  • overload protection can thereby be avoided Realize that the axle pin of the lever is mounted to avoid spring loading. It cannot therefore occur that, when the operating handle is in the open position, when the control cam is acted upon by the lever, turning the number plate leads to destruction of the lock mechanism. Rather, with such a rotation, the pivot of the lever can deflect against spring loading. Due to the spring load, it is also realized that after a possible rotation of the number disk in such a case, it always returns to its neutral position. In a simple manner, the storage is formed by slots pointing towards the floor. When the overload protection comes into effect, these allow the axle journal to move in the direction of the ground. However, the spring load always leads the journal back to its starting position by acting on the bottom of the slot.
  • the spring load acting on the axle journal can be formed by bar springs running transversely to the housing, which act on the end sections of the axle journal.
  • Another overload protection device is a spring-loaded slip clutch between the window sash and the operating handle / rotating nut. If the permutation lock assumes its locking position, no major forces can be directed into the lock mechanism. As soon as the rungs of the window slide step against the locking sleeves and prevent further displacement of the window slide, the slip clutch allows a further displacement of the operating handle / wrench, so that only the rungs step against the locking sleeves with a predeterminable force. In particular, this measure proves to be advantageous in the case of a rotary nut-operated permutation lock, since relatively large forces can be applied here.
  • This overload protection sees in detail so that the rotary nut is coupled with a rotary actuating handle in such a way that there is a rib / groove engagement which can be disengaged against the action of the spring.
  • This assigned control bevels allow an axial displacement of the rotary operating handle relative to the turning nut while lifting the ribs / Nutein handle with increasing load.
  • the spring loading is achieved by means of a compression spring arranged in a cup-shaped recess in the rotary actuation handle. This is accordingly in a hiding position and does not take up additional space.
  • the compression spring is supported on a plate arranged on the front end of the axis of rotation of the rotary actuation handle.
  • a permutation lock 1 designed according to the invention is assigned to a piece of furniture 4 having drawers 2, 3.
  • the closure housing 5 of the permutation lock is let into the front plate 3 '.
  • the closure housing 5, which is designed in the form of an elongated box, has a base 6 with transverse side walls 7, 8 and longitudinal side walls 9, 10 extending therefrom.
  • the transverse side walls 7, 8 carry an undrotatable, immovable axis of rotation 11 for receiving number disks 12 of circular cross-section which are arranged next to one another at a distance.
  • Each number plate 12 is in coupling tooth engagement to a respective rotatable on the axis of rotation 11 locking sleeve 13 which passes through a central bore of the number plate 12, so that there is an indirect storage thereof on the axis of rotation 11.
  • a radially directed projection 14 extends from each locking sleeve 13 and engages in a tooth gap 15 of the number plate 12 in a form-fitting manner. There are ten such tooth gaps in the same circumferential distribution on each number plate 12, so that the locking sleeve 13 can assume ten different positions relative to the number plate 12.
  • a compression spring 16 arranged on one free end of the axis of rotation 11 loads the locking sleeves 13 in the engagement direction via a plate 17.
  • the displacement of the plate 17 is limited by two webs 18 directed towards the housing and extending from the longitudinal side walls 9, 10.
  • pins 19 serve as a rotation lock for the plate 17.
  • the webs 18 ensure that the spring force by the plate 17 supported on them no longer acts on the locking sleeves 13.
  • radially projecting collars 20 of the locking sleeves 13 engage in recesses 21 facing them on the broad sides of the number disks 12 in a form-fitting manner.
  • Each locking sleeve 13 has a truncated cone-shaped annular collar 22 which starts from it and is provided with a flattened portion 23.
  • the cross-sectional taper points in the direction of the number plate 12 coupled to it.
  • All locking sleeves 13 are arranged on the axis of rotation 11 so that they abut each other.
  • An intermediate ring 24 is assigned to the locking sleeve 13 facing the transverse side wall 8.
  • Aligned with the slot 27 is a recess of a cover cap 28 which is U-shaped in cross section and extends over the closure housing 5 from below.
  • the slot 27 is composed of a slot section 27 'running parallel to the axis of rotation 11 and two slot sections 27' arranged at right angles to this. 'and 27' ''.
  • the setting lever 26 is moved from the slot section 27 '' into the slot section 27 '' 'exclusively for the purpose of changing the key secret, cf. Dash-dotted representation in Figure 18.
  • a displacement of the adjusting lever 26 causes a displacement of the locking sleeves 13 against spring action, the coupling engagement between the radially directed projections 14 of the locking sleeves 13 and the number disks 12 is canceled. Then these can be brought into a different rotational position and, after returning the adjusting lever 26 to the starting position, come into clutch engagement, the flats 23 of the locking sleeves 13 coming into a different position to the number disks 12.
  • Each number disk 12 is provided on its circumference with ten latching cutouts 29 arranged in the same angular distribution. Between these, each number plate carries the digits from 0 to 9 corresponding to the ten different coupling positions of the locking sleeves 13 the number disks 12.
  • the number disks 12 are rotated with the locking sleeves 13 in such a way that their flats 23 face away from the bottom 6 of the closure housing 5 and run parallel to a window slide 30.
  • the latter is frame-shaped and has a shorter length than the lock housing 5.
  • One frame cross leg 31 is wider than the other frame cross leg 32 and forms a hole 33 in the middle for engaging the coupling pin 34 of an operating handle 35.
  • Extending between the latter and the window slide 30 is a cover plate 36 which overlaps the closure housing 5 and is provided with recesses 37 in flush alignment with the number disks 12.
  • the window slide 30 is supported by the webs 18 as well as by further webs 38 of the longitudinal side walls 9.10.
  • the frame longitudinal leg 39 facing the longitudinal side wall 10 continues in the direction of the housing into a bend 40.
  • This is provided with two pins 41 arranged one behind the other at the same height and pointing in the direction of the longitudinal side wall 10, which engage in angular slots 42 of a slide 43.
  • This is guided between the webs 18 and 38 and between the longitudinal side wall 10 and the bend 40.
  • the slide 43 thus extends parallel to the axis of rotation 11 and is displaced transversely to its plane of movement when the window slide 30 is displaced by means of the operating handle 35.
  • the angular slot 42 is composed of a short slot section 42 ', which is oriented parallel to the axis of rotation 11, and a longer slot section 42''which rises to it.
  • a short slot section 42 ' which is oriented parallel to the axis of rotation 11, and a longer slot section 42''which rises to it.
  • the pin 41 In the locked position of the permutation lock, cf. in particular FIGS. 3 and 4, is the pin 41 at the end of the slot portion 42 '. As long as the pin 41 moves in the slot section 42 ', there is no displacement of the slide 43. There is thus an idle stroke of the window slide 30 to the slide 43.
  • Each number plate 12 is assigned a locking lever 44, the free end 44 'of which is supported on the lower edge of the slide 43. Furthermore, the locking lever 44 engages with a locking tooth 44 ′′ in one of the locking cutouts 29 of the number plate 12.
  • the locking lever 44 is made of the same material from the longitudinal side wall 9 of the closure housing 5, which is preferably made of appropriate plastic.
  • Each number plate 12 forms a control curve 45 on the broad surface opposite the recess 21. This is designed as a disk with a heart-shaped circumference.
  • the tip 45 'of the heart-shaped control curve points into the area between two mutually adjacent latching cutouts 29.
  • a rod-shaped spring element 46 is supported on the heart base 45' 'opposite the heart tip, which runs either flat or fluted.
  • the spring element 46 is anchored in the closure housing base 6. It can therefore never occur that the force component exerted by the spring element 46 is conducted into the heart tip 45 '.

  • These rungs 47 are designed as spring-loaded bascule bridges, which extend beyond the flats 23 of the locking sleeves 13.
  • a torsion spring 50 assigned to a bearing journal 48 is used to spring load each bascule bridge or rung 47, which is supported on the one hand on the longitudinal frame leg 39 and on the other hand on a stop web 51 which overlaps the latter.

  • Locking the drawers 2, 3 requires the inserted position of the same. Then the operating handle 35 is to be shifted in the direction of the arrow z, the window slide 30 being carried along. Its rungs 47 step with their control bevel 47 ′′ against the frustoconical flank of the ring collar 22, cf. 12, 15 and 16.

  • the window slide 30 also continues into a bolt tail 92, on which a rotary actuation handle 110 engages. This is the holder of a knob 111.
  • a turning nut 97 can be brought from one to the other end position, cf. Fig. 50 and 52.
  • the turning nut 97 is also provided with an arm 96 which engages in a locking engagement opening 95 of the bolt tail 92 of the window slide 30.
  • a slip clutch 112 is switched on between the window slide 30 or bolt tail 92 and the rotary actuation handle 110.
  • the rotary nut 97 is coupled to the rotary actuation handle 110 in such a way that there is a rib / groove engagement which can be disengaged against the spring action.
  • a rib 113 with a trapezoidal cross section extends from the side of the rotary nut 97 facing the rotary actuating handle 110, which rib fits in a form-fitting manner in a diametrical groove 114 of the opposite end of the rotary actuating handle 110.
  • the side flanks of the rib 113 and the groove 114 run towards one another in a roof shape.
  • the rotary nut 97 is mounted on an axis of rotation 115 anchored in the closure housing 5. At the same time, this passes through a bore 117 of the rotary actuation handle 110 opening into a cup-shaped recess 116.
  • the axis of rotation 115 protrudes into the cup-shaped recess 116 and carries a fixed distance there from the recess bottom its connected plate 118. Between this and the base of the recess extends on the axis of rotation 115 a spring designed as a compression spring 119, which maintains the joint engagement between rib 113 and groove 114.
  • a set of disc springs could also be used to provide a short spring travel to be able to transmit greater forces.
  • the above-described slip clutch 112 fulfills the task of overload protection. This is the case if the correct key secret is not set. If the rotary actuation handle 110 is displaced by means of the knob 111, the window slide 30 is carried by the rotary nut 97 by a small amount. until its rungs 47 act on the locking sleeves 13. If the rotary actuation handle 110 is displaced further, this leads to a superimposed axial displacement of the rotary actuation handle 110 against the force of the compression spring 119 occurring over the inclined flanks of the rib 113 and the groove 114, cf. Fig. 51 and 54. The composite engagement or the slip clutch 112 is released so that a further displacement of the rotary operating handle 110 does not exert any forces on the lock mechanism.
  • the three levers 120 arranged one behind the other are connected to one another by a bridge 121.
  • Cross pins 122 are formed on the shorter lever arm 120 ′ of the outside lever 120, which engage in transverse slots 123 of the slide 43.
  • a shaft journal 124 which extends through the latter and which lies in slots 125 of the closure housing 5 which are open towards the bottom 6, is used to mount the levers 120.
  • Two rod springs 126 extending transversely in the closure housing 5 act on the ends of the axle pin 124 and bring this into abutment position at the bottom of the slots 125, cf. Fig. 47.
  • the longer lever arm which is supported in the basic position on the bottom 6 of the closure housing, forms a flank 120 ′′ interacting with the control curve 45.
  • the spring tongues 127 assigned to the number disks 12 are mounted about an axis 128 on the housing side.
  • Each spring tongue 127 is equipped with a latching tooth 127 'which engages in a latching cutout of the number disk 12 in a spring-loaded manner.
  • Compression springs 125 which act on the free end of the spring tongues 127, serve for spring loading. The free end of the same lies in the range of movement of the slide 43 and is controlled by it as in the aforementioned exemplary embodiments.
  • moving the window slide 30 requires the correct setting of the key secret by means of the number disks 12.
  • the locking sleeves 13 are rotated such that they allow the rungs 47 of the window slide 30 to pass.
  • the window slide 30 effects a downward displacement of the slide 43 via the pin / slot control, the spring tongues 127 being brought out of engagement with the number disks 12.
  • the slider 43 pivots the levers 120, which with their flanks 120 ′′ act on the control cam 45 and cause the number disks 12 to rotate into a certain basic position that differs from the key secret, cf. Fig. 48. If the number disc 12 is rotated unnecessarily in this position, a position as shown in Fig. 49 occurs.
  • the sloping flank 120 ′′ of the lever 120 is acted upon by the control curve 45. Due to the existing pin / slot engagement between cross pin 122 and cross slot 123, the axle pin 124 is displaced in the downward direction against spring loading, so that no destructive constraining forces occur due to this evasive movement of the lever (s) 120. If the number plate 12 is released from the position according to FIG. 49, the spring load acting on the axle journal 124 brings about the position of the number plate 12 according to FIG. 48.
  • adjusting lever 130 is now designed as a pivot lever.
  • the adjusting lever 130 is mounted around cross pins 131 near its end engaging the axis of rotation 11.
  • a pivoting of the adjusting lever 130 leads to a displacement of the locking sleeves 13 against the compression spring 16 which loads them.
  • a displacement is done when the key secret is to be changed.
