Definitions

  • the invention relates to a combination lock with a rotary knob, with a cam disc and with an engaging lever hinged to a bolt, which engages with a hook-like projection in particular in a recess of the cam disc with the correct setting of an opening secret of the lock, so that a rotation of the cam disc by means of the bolt of the drop lever, the rotary knob is provided for setting individual values of the opening secret at different angles of rotation and each time a value is actuated for actuating an electrical switch assigned to the respective value, it can also be rotated axially so that the individual setting values can be set via the switches assigned to them can be fed electrically to a memory which contains the relevant opening secret and an electric motor arranged inside a slide controlled in such a way that, with the correct setting of the opening secret, a coupling member mounted on the slide is adjusted in the region of a first effective surface of a cam of the cam disk, so that the rotation of the cam disk actuates this slide, which in turn acts on a lever arm of the drop lever and pushes
  • a tumbler lock is therefore known, in which the opening secret is contained in an electronic memory and the rotary knob is used to actuate the actual values of the opening secret via individual switches in the correct order, so that the Comparison between the setting made with the rotary knob and the stored value can. If the values match, the actuating lever is brought into the coupling position of the cam disk by means of an electrical actuation, with this previously known solution the holding lever being held on a lateral finger with the aid of an additional disk which, after setting the correct opening secret, is rotated so that the engaging lever can fall into the opening of the cam disc.
  • the invention is therefore based on the object to provide a combination lock of the type mentioned, in which an unnoticed stop of the slide in its open position opposite to the starting position is avoided.
  • the tumbler lock defined at the outset is characterized in that the slide has a fixed projection facing the cam side, which is acted upon by turning back the cam disc to close the bolt by a second active surface of the cam disc, so that the slide is rotated by the Cam disc can be forcibly moved back to its starting position when the lock is closed.
  • a corresponding first active surface can be provided on it, which acts on the projection of the slide when the cam disc is rotated against the direction of rotation with which the lock is opened. This means that when the lock is closed, the slide is forcibly moved back to its initial position, because the first active surface of the cam disc now acts on the projection of the slide so that the slide is moved back again. Even if it should be slightly jammed, this forced adjustment results in any event in the return adjustment of this slide so that it is available again for the next opening operation.
  • first active surface and the second active surface are arranged approximately coaxially one behind the other on the cam disk. This ensures that when the cam is rotated Opening the lock, the coupling member and the first active surface cooperate and thus the slide is shifted at the right time so that the drop lever with its hook-like projection can be pivoted into the drop opening, so that a further rotation of the rotary knob, at which now the first effective surface the area of the coupling member is pivoted out, the lock bolt can be withdrawn.
  • the slide can be displaced against the force of a return spring when the drop lever is pivoted into the cam disk. Although this somewhat increases the force to be exerted by the user when the bolt is opened, it can be achieved, however, that the slide is already pushed back into the starting position after the opening movement with the lock still open, if this return spring is sufficiently strong for this.
  • the bolt is moved back into the closed position, the user does not need to apply the force to move the slide back into its initial position. In any case, the closing of the lock becomes easier when such a return spring is present. Nevertheless, pushing the slide back into the starting position is ensured if this spring fails.
  • the force of the return spring for the slide can be chosen so large that it at least supports the displacement of the slide into its initial position.
  • this resetting force is not for an automatic resetting is sufficient, as long as the return spring works - the return of the slide is supported and thus the closing movement at the lock is facilitated. If the force is sufficient for an automatic reset, the user does not have to move the slide back when the lock is closed, as long as the spring works.
  • the lever arm provided on the drop lever, for pivoting it in the coupling position can have a pin that can be moved against a compression spring and protrudes out of it, with its pin Free, protruding end engages in a recess of the slide and at least in the open position of the drop lever runs obliquely in the sense that it has something with its end engaging on the slide against the feasible sliding direction when opening, and this pin can when moving the slide to Compensation for the path difference between the circular arc described by the lever arm and the pin and the straight displacement of the slide against the compression spring in the lever arm.
  • an opening receiving the pin and the compression spring for the pin can be provided in the latch lever, at least in some areas has a polygonal, for example quadrangular, in particular square cross-section and one or both ends of the compression spring can be parallel to a wall of the opening up to the adjacent wall arranged at an angle thereto run and / or at least the end windings of the compression spring be of polygonal or quadrangular design, so that the opening encloses the ends of the compression spring or the polygonal windings in a form-fitting manner.
  • the compression spring cannot twist even under pressure and even if it is broken, the fracture points continue to support each other because the fragments cannot be twisted into one another under pressure.
  • this spring breaks, the full function of the drop lever and its adjustment is retained.
  • the windings of the compression spring are wound square over their entire length.
  • the spring then has no possibility at all to perform additional relative movements in the direction of rotation when it is actuated, so that in any case it exerts its spring action even in a broken state and then behaves as if two such springs were arranged one behind the other in the opening.
  • the pin in the interior of the drop lever on the compression spring can have a continuation which fits into the interior of the compression spring and which is shorter than the spring at least by the spring travel when compressed.
  • the compression spring is even guided over a large part of its length and in particular under pressure inside and outside, so that not only the risk of spring breakage is reduced, but also in the event of such a break, the spring pieces cannot be pressed into one another and thereby the spring action entirely or partially lost.
  • the pin can have a quadrangular, in particular square cross-section - whereby it corresponds to the quadrangular or square cross-sectional shape of the opening receiving it fits - and that its end cooperating with the slide is rounded, the center or axis of the curvature of this rounding being approximately parallel to the pivot axis of the drop lever, and that the rounded region of the pin on the areas overlapping it in the direction of the slide the recess of the slide is in contact with the line.
  • a spherical rounding of the pin end this results in a better contact and thus a safe actuation when pivoting the insertion lever by pivoting the pin.
  • the pin end can perform a rolling motion with respect to the slide to be moved in a straight line when it is pivoted.
  • the cam disk has a sliding curve on its circumference adjacent to the opening and the bolt has an extension tour. It can thereby be achieved that the rotation of the cam disc when closing the lock does not have to move the bolt or not exclusively via the drop lever in the closed position, but rather that the bolt is easily moved directly on the extension tour, so that the drop lever remains largely unloaded by the cam disc and can thus be easily lifted out of the area of the opening by the compression spring of the lever arm and pivoted into its locking position on a corresponding locking projection of the lock case.
  • This push-out tour also has the advantage that the bolt in the closed position, should it be exposed to a pressure load in the opening direction, can be supported with its push-out tour directly on the cam disc, so that the lever is not pressed and wedged against its locking projection or locking point and on Opening the Can prevent lock. Even if pressure is exerted on the bolt, the slide can be moved to open the lock, thereby pivoting the lever into the opening in the cam, so that the bolt can then be withdrawn by turning the rotary knob again.
  • a combination lock designated as a whole by 1, hereinafter also referred to as "lock 1" has a rotary knob 3 and a cam disc 4 for actuating it to set an opening secret and move a bolt 2.
  • An latch lever 5 is articulated on the bolt 2, which if the opening secret is set correctly, a hook-like projection 6 is adjustable and engages in an incidence opening 7 of the cam disk, as can be seen in FIGS. 5 and 6.
  • rotation of the cam disk 4 causes the bolt 2 to be retracted from the position shown in FIG. 3 into the position shown in FIG. 5 by means of the drop lever 5 articulated on it, which means that the lock 1 is open.
  • the rotary knob 3 is used in the usual way to set individual values of an opening secret, with one in a viewing window 8 the housing 9 adjacent to the rotary knob 3, these values 10 become visible one after the other. In Figure 1, for example, the value "5" is currently set. By setting the rotary knob 3 at different angles of rotation, different values of this type can be set in succession.
  • the rotary knob 3 for actuating a switch 11 assigned to the respective value can be axially adjusted in addition to its rotatability.
  • the individual setting values can thus be supplied electrically to a memory, for example a microprocessor, via the switches 11 assigned to them. A value is thus set in each case by turning the rotary knob and pressing down the rotary knob 3 is saved.
  • the memory contains the relevant opening secret of the lock 1 and, with the correct setting, controls an electric motor 12 inside a slide 13 to be explained in such a way that, with the correct setting, a coupling member 14 on this slide 13 adjusts into the area of a first active surface 15 of the cam disk 4 is - wherein this first effective surface 15 is another cam of this cam disc 4 - so that the rotation of this cam disc 4 actuates this slide 13.
  • the first active surface 15 is located on a side facing away from or opposite its incidence opening 7.
  • the slider 13 can be seen in FIGS. 3, 5 and 6 in each case below the cam disk 4 approximately on the lower wall 16 of the lock housing, where a greater distance is provided between the fastening points 17 than corresponds to the length of this slider 13.
  • the slide 13 can thus be seen from the starting position in FIG Attachment point 17 strikes, shifted to the right, as can be seen in Figures 5 and 6.
  • the slider 13 in turn engages a lever arm 18 of the drop lever 5, which lever arm 18 is directed downward relative to the pivot bearing 19 of the drop lever 5 and is on the other side opposite the part of the drop lever 5 which has the hook-like projection 6.
  • lever arm 18 is pivoted counterclockwise to the right, this also means that the projection 6 is lowered from the position shown in FIG. 3 into the coupling position shown in FIGS. 5 and 6.
  • the lever arm 18 is pivoted in the corresponding direction, as a result of which the drop lever 5 comes into the engaged position.
  • the first active surface 15 of the cam disk 4 and its drop opening 7 are coordinated with one another in such a way that the displacement of the slide 13 and the pivoting of the drop lever 5, in particular, are ended approximately simultaneously. This can be seen in FIG. 5, where the position has just been reached in which the first active surface 15 of the cam disk 4 has been pivoted out of the area of the coupling member 14 of the slide 13 and the bolt has been retracted into the open position. A further rotation of the cam disc 4 is no longer possible in this position and is no longer necessary because the bolt 2 is unlocked.
  • the coupling member 14 which can be rotated by the electric motor 12, can engage in its inactive position in a recess 14a of a housing wall, so that this coupling member 14 can have a sufficiently large length, but nevertheless a space-saving arrangement of the slide 13 is possible.
  • 1 can be dimensioned such that the coupling member 14 also locks the slide 13 in this inactive position, because the recess 14a is so short in the sliding direction that the coupling member 14 in this position from the end of the recess 14a as Attack is overlapped. If the slide 13 is returned to its starting position according to FIG. 3 in a manner to be described, this coupling member 14 can also be rotated back into this inactive blocking position with the aid of the motor 12.
  • the slide 13 has a projection 20 which is fixed on its upper side facing the cam disk 4 and faces the cam disk, while above all in FIGS. 3 and 4 it is indicated that the cam disk 4 has a second active surface 21 which, when the cam disk 4 is turned back according to the arrow Pf1 in FIG. 6, comes into operative connection with the projection 20 of the slide 13 to close the bolt 2.
  • the slide 13 is therefore forcibly pushed back into its starting position shown in FIG. 3, this displacement of the slide 13 being indicated in FIG. 6 by the arrow PF2.
  • the first active surface 15 and the second active surface 21 are arranged approximately coaxially to one another on the cam disk 4, whereby they each have somewhat different contours and are located between the - rotatable - coupling member 14 and the projection 20 of the slide 13.
  • the rotation of the cam disk 4 in one direction according to the arrow Pf3 in FIG. 5 then causes the coupling member 14 to interact with the first active surface 15 in the sense of a displacement of the slide 13 from its initial position to the right and thus a pivoting of the drop lever 5 into the engagement position on the cam disc 4 while by the opposite twist 6, the second active surface 21 acts on the projection 20 of the slider 13 and thus pushes the slider 13 back in the direction of the arrow PF2.
  • the slide 13 can be displaced against the force of a return spring 22 when the drop lever 5 is pivoted into the cam disk 4.
  • This return spring 22 can be seen as a clock spring, which is arranged approximately around the pivot bearing 19 of the drop lever 5 and engages with a resilient leg 23 on the front side of this slide 13 which is in the direction of displacement of the slide 13 when it is opened.
  • the force of this return spring 22 for the slide 13 is so great that it supports the displacement of the slide 13 back to its starting position or can even be carried out alone.
  • the latter has the advantage that, when the spring 22 is functioning, the slide 13 is already pushed back into the starting position according to FIG. 3 when the lock is still open according to FIG.
  • the slide 13 performs an essentially straight, guided back and forth movement, while the lever arm 18 makes a pivoting movement with respect to its pivot bearing 19, which therefore means an arc.
  • the coupling arm 18 provided on the drop lever 5, for pivoting it in the coupling position has a pin 25 which can be displaced in its longitudinal direction against a compression spring 24 and protrudes somewhat from the lever arm 18 and which has its free, projecting end 26 in a recess 27 engages on the upper side of the slide 13, that is to say has a toothing with this slide 13.
  • the lever arm 18 and its pin 25 extend obliquely in the sense that its end 26 engaging the slide 13 points somewhat against the sliding direction that can be carried out when opening, i.e.
  • this pin 25 forms with the sliding direction or the extension of the slide 13 an acute angle, which can be clearly seen in Figure 3. If the slide is moved, this causes a corresponding pivoting of the pin 25 and thus the lever arm 18 into a position in which this angle becomes larger and, for example, according to FIGS. 5 and 6, can be almost a right angle.
  • the pin 25 in the lever arm 18 is adjustable against a compression spring 24.
  • the lever arm 18 can thus be shortened by pressing the pin 25 deeper into the lever arm 18, that is to say the length of the lever arm 18 adapts.
  • the free end 26 of the pin 25 receiving recess 27 of the slider 13 is limited on both sides of the pin 25, that is, both in the sliding direction and counter to the sliding direction there is a positive fit between the end 26 of the pin 25 and the slider 13.
  • the pin 25 is in the initial position of the slide 13 according to FIG. Fig.3 fixed positively, so that a blow to the lock 1, which could cause a brief pivoting of the lever 5, is prevented and the pin 25 can not slide off the slider 13.
  • the pin 25, which is inclined in the disengaged position of the drop lever 5, is thus positively gripped and held at its end 26 on the side facing away from the sliding direction, as can be clearly seen in FIG. 3.
  • the compression spring 24 for the pin 25 is therefore important for the mechanical functionality of the lock. So that it can fulfill its task even if it should break for any reason, it is in a corresponding opening 29 of the drop lever 5, which opening 29 also receives the pin 25, arranged compression spring 24 for the pin 25 at least in some areas with a polygonal, for example quadrangular, in particular square cross section, at least the turns forming the end of this compression spring 24 being of polygonal or quadrangular design. It is even more favorable if the windings of the compression spring 24 are wound in a correspondingly polygonal or quadrangular manner over their entire length and are thus largely adapted to the inner cross section of the opening 29 so that a rotation of the spring or fragments of the spring is avoided and the spring cannot dodge sideways. If it breaks, its ends cannot be pushed into each other, so that the spring 24 then maintains its effect in the manner as if two springs were supported against one another.
  • the pin 25 in the interior of the drop lever 5 or the lever arm 18 on the compression spring 24 can have a continuation 30 which fits into the interior of the compression spring 24 and which is shorter than the compression spring 24, at least by the spring travel when compressed, but also the compression spring 24 supports and leads inwards.
  • the pin 25 can also have a quadrangular, in particular square, cross-section, corresponding to the cross-sectional contour of the opening 29, that is to say it can be arranged in a form-fitting manner in the opening 29 only in its direction of longitudinal extension.
  • its end 26 cooperating with the slide 13 can be rounded such that the center or axis of the curvature of this rounding - as can be seen in FIGS. 3, 5 and 6 - runs approximately parallel to the pivot axis 19 of the drop lever.
  • the end 26 can roll on the slide 13 during its relative movement with respect to the latter.
  • the rounded area of the pin 25 lies against the areas acting on it and the recess 27 of the slide 13 with line contact.
  • an opening secret can include seven values.
  • the motor 12 is started, which pivots the coupling member 14 from the inactive position according to FIG. 2 into the coupling position according to FIG. 4, so that the first active surface 15 of the cam disk 4 can now cooperate with it.
  • the cam disc 4 is rotated and thus the slide 13 is shifted from the position shown in FIG. 3 to the right, which causes the aforementioned pivoting of the drop lever 5 into the coupling position.
  • a further rotation then pulls the latch 2 back in the open position according to FIG. 5.
  • the cam disk 4 has a sliding curve 32 and the periphery adjacent to the inlet opening 7 Riegel carries an extension tour 33, on which this sliding curve 32 engages during the closing movement according to FIG. 6.
  • the rotary movement of the cam disc 4 is not transmitted via the drop lever 5 - which would also be possible - but directly to the bolt 2.
  • the region adjacent to the push-out tour 33 supports the closed bolt on the cam of the cam disk 4, which limits the incidence opening 7 for cooperation with the hook-like projection 6 of the incidence lever 5. This can be clearly seen in FIG. 3.
  • the slider 13 Since the slider 13 is forcibly moved back into its starting position with the aid of the cam disk 4, there is no need to fear that it will remain in its shifted position after actuation, which still enables the lock 1 to be locked without the user misaligning the slider 13 noticed. If the return spring 22 provided in the exemplary embodiment is present and effective, the lock can be closed more easily, so that the user may notice the failure of this spring 22 if the actuation is difficult.
  • the combination lock 1 has a rotary knob 3 with which a cam disk 4 can be rotated in order to actuate an lever 5 articulated on a bolt 2 of the lock 1 and thereby withdraw the bolt in the open position.
  • a rotary knob 3 with which a cam disk 4 can be rotated in order to actuate an lever 5 articulated on a bolt 2 of the lock 1 and thereby withdraw the bolt in the open position.
  • the slider 13 has a fixed projection 20 facing the cam disk 4 and the cam disk 4 has a second effective surface 21 which, when the cam disk 4 is turned back, closes the latch 2 in operative connection with the projection 20, so that the slide 13 is rotated the cam disk 4 is forcibly pushed back into its starting position when the lock 1 is closed, if a return spring 22, if provided, fails.
  • the lock 1 is in any case ready for the next opening operation after it has been closed, even if a return spring 22 would not move the slide 13.

Serrure (1) à combinaison chiffrée, présentant un bouton tournant (3), un disque à cames (4) et un loquet retombant (5) qui est articulé sur un pêne (2) et qui, lors du réglage correct d'un code secret d'ouverture de la serrure (1), s'engage dans un orifice de retombée (7) du disque à cames (4), notamment par une protubérance (6) du type crochet, de telle sorte qu'une rotation du disque à cames (4) rétracte le pêne (2) au moyen du loquet retombant (5), le bouton tournant (3) étant prévu pour régler des valeurs individuelles du code secret d'ouverture parmi différents angles de rotation, et pouvant être déplacé axialement en plus de son aptitude à tourner, lors de chaque réglage d'une valeur, en vue de l'actionnement d'un interrupteur électrique (11) affecté à la valeur considérée, si bien que les valeurs réglées individuelles peuvent être délivrées électriquement, par l'intermédiaire des interrupteurs (11) qui leur sont affectés, à une mémoire qui renferme le code secret d'ouverture pertinent et active un moteur électrique (12) logé à l'intérieur d'un coulisseau (13), de façon telle que, moyennant un réglage correct du code secret d'ouverture, un organe d'accouplement (14) monté sur le coulisseau (13) soit déplacé jusque dans la région d'une première surface opérante (15) d'une came du disque à cames (4), de sorte que la rotation du disque à cames (4) actionne ce coulisseau (13) qui, à son tour, vient en prise avec un bras (18) du loquet retombant (5) et amène ce dernier, par pivotement, a la position de venue en prise, les positions de la première surface opérante (15) et de l'orifice de retombée (7) étant mutuellement coordonnées de manière que le coulissement du coulisseau (13) et le pivotement du loquet retombant (5) soient achevés à peu près simultanément, caractérisée par le fait que le coulisseau (13) comporte un mentonnet (20) tourné vers le disque à cames (4) et sollicité, au cours de la rotation rétrograde du disque à cames (4) pour fermer le pêne (2), par une seconde surface opérante (21) du disque à cames (4), de telle sorte que, lors de la fermeture de la serrure (1), le coulisseau (13) puisse être ramené à sa position initiale, par coulissement forcé, sous l'effet de la rotation du disque à cames (4).
  2. Serrure à combinaison chiffrée, selon la revendication 1, caractérisée par le fait que la première surface opérante (15) et la seconde surface opérante (21) sont agencées en succession sur le disque à cames (4).
  3. Serrure à combinaison selon la revendication 1 ou 2, caractérisée par le fait que, lors du pivotement rentrant du loquet retombant (5) dans le disque à cames (4), le coulisseau (13) peut être animé d'un coulissement en s'opposant à la force d'un ressort de rappel (22).
  4. Serrure à combinaison selon la revendication 3, caractérisée par le fait que la force du ressort de rappel (22), associé au coulisseau (13), est choisie suffisamment grande pour amplifier au moins le coulissement du coulisseau (13) jusqu'à sa position initiale.
  5. Serrure à combinaison selon l'une des revendications 1 à 4, caractérisée par le fait que le bras (18), prévu sur le loquet retombant (5) et servant à le faire pivoter à une position d'accouplement, présente une broche (25) qui dépasse dudit bras, peut coulisser en s'opposant à un ressort de pression (24), pénètre par son extrémité libre saillante (26) dans une creusure (27) du coulisseau (13) et s'étend à l'oblique, au moins dans la position ouverte du loquet retombant (5), de manière à être orientée, par son extrémité (26) venant en prise avec le coulisseau (13), sensiblement vers la direction du coulissement pouvant être effectué au stade de l'ouverture ; et par le fait que, lors du coulissement du coulisseau (13), cette broche (25) peut jouer dans le bras (18) du loquet, en s'opposant au ressort de pression (24), afin de compenser la différence de distance entre l'arc de cercle décrit par le bras (18) du loquet et par la broche (25), et le coulissement comparativement rectiligne du coulisseau (13).
  6. Serrure à combinaison selon l'une des revendications 1 à 5, caractérisée par le fait que la creusure (27) du coulisseau (13), recevant l'extrémité libre (26) de la broche (25), est limitée de part et d'autre de ladite broche (25).
  7. Serrure à combinaison selon l'une des revendications 1 à 6, caractérisée par le fait qu'un perçage (29), prévu dans le loquet retombant (5) et recevant la broche (25) et le ressort de pression (24) destiné à cette broche (25), présente, au moins par zones, une section transversale polygonale, par exemple rectangulaire et notamment carrée ; et par le fait qu'une ou les deux extrémité(s) (24a) du ressort de pression (24) s'étend(ent) parallèlement à une paroi (29a) du perçage (29), jusqu'à la paroi voisine (29b) agencée perpendiculairement à cette dernière, et/ou au moins les spires extrêmes du ressort de pression (24) sont de réalisation polygonale ou rectangulaire, de telle sorte que le perçage (29) ceinture les extrémités (24a) du ressort de pression (24) ou les spires polygonales, par concordance de formes et avec verrouillage antirotation.
  8. Serrure à combinaison selon l'une des revendications 1 à 7, caractérisée par le fait que les spires du ressort de pression (24) sont enroulées rectangulairement sur toute la longueur de celui-ci.
  9. Serrure à combinaison selon l'une des revendications 1 à 8, caractérisée par le fait que la broche (25), appliquée contre le ressort de pression (24) à l'intérieur du loquet retombant (5), comporte un prolongement (30) qui s'ajuste dans l'espace interne du ressort de pression (24) et est plus court que ledit ressort (24), d'une valeur représentant au moins la course élastique parcourue lors de la compression.
  10. Serrure à combinaison selon l'une des revendications 1 à 9, caractérisée par le fait que la broche (25) présente une section transversale rectangulaire et notamment carrée, correspondant au perçage (29) ; par le fait que son extrémité (26) coopérant avec le coulisseau (13) est arrondie, le centre ou l'axe de la courbure de cet arrondi s'étendant à peu prés parallèlement à l'axe de pivotement (19) du loquet retombant (5) ; et par le fait que la région arrondie de la broche (25) porte, avec contact linéaire, contre les régions de la creusure (27) du coulisseau (13) qui coiffent ladite région dans la direction du coulissement.
  11. Serrure à combinaison selon l'une des revendications précédentes, caractérisée par le fait que le disque à cames (4) présente une came de poussée (32) sur son pourtour, au voisinage de l'orifice de retombée (7), et le pêne (2) comporte une dépouille de poussée (33) en vue de coopérer avec cette came de poussée (32) lorsque ledit pêne (2) est poussé vers sa position fermée.
  12. Serrure à combinaison selon l'une des revendications précédentes, caractérisée par le fait que l'organe d'accouplement (14) est une clenche rotative arrêtant le coulisseau (13) dans sa position initiale.
