Definitions
- the invention relates to an electronic lock.
- locks known to the applicant furthermore comprise a storage arm made of magnetic material able to rotate about an axis between a rest position and a storage position, in response to the unlocking command. electric, even if the locking lever is immobilized by the locking member.
- the invention aims to remedy one or more of these disadvantages.
- stator and the storage arm are shaped so that the storage arm moves from its rest position to its storage position with zero power consumption and optimized space.
- the figure 1 represents a barrel 2 of a double barrel lock whose other barrel is not shown in the figure 1 .
- This barrel 2 extends in depth along a direction Z perpendicular to horizontal and vertical directions, respectively X and Y.
- the terms "lower” and “upper” are defined with reference to the direction Y.
- the two barrels are housed in a conventional manner in a door (not shown) and are arranged symmetrically with respect to the average plane P of the door.
- the two barrels are positioned and connected in a conventional manner to one another by a connecting rod (not shown) which has in its middle a bulge serving as a spacer to maintain a predefined spacing between the two barrels.
- a connecting rod (not shown) which has in its middle a bulge serving as a spacer to maintain a predefined spacing between the two barrels.
- a bit (not shown) which can be rotated by a rotor 4 of one or the other of the two barrels when an appropriate key, for example a key 5 is introduced into a channel 6 of the rotor 4 and manually rotated by a user.
- the bit When rotated by the key 5 and the rotor 4, the bit controls a conventional lock mechanism (not shown) which causes the displacement of at least one bolt of the lock in a direction allowing the opening of the lock. door or in a direction prohibiting the opening of the door according to the direction of rotation of the key 5.
- a conventional lock mechanism (not shown) which causes the displacement of at least one bolt of the lock in a direction allowing the opening of the lock. door or in a direction prohibiting the opening of the door according to the direction of rotation of the key 5.
- the rotor 4 of the barrel 2 is rotatably mounted in a profiled stator 7.
- the stator 7 is itself housed in an outer sheath 8 having the same profile.
- the stator 7 has a standardized profile, called "European”. Still in the example, the axis of rotation of the rotor 4 is parallel to the direction Z.
- the barrel 2 conventionally comprises several pairs of stator and rotor pins, which are arranged in pairs, end to end, in corresponding pairs of aligned housings respectively formed in the stator 7 and in the rotor 4. arrangement of the rotor and stator pins is well known, this one has not been shown to simplify the figure 1 .
- the key 5, which has for example a substantially rectangular cross section, has on at least one of its two large faces, preferably on its two large faces, indentations and / or reliefs which cooperate with the rotor pins.
- the imprints and / or the reliefs are shaped and the lengths of the rotor pins are chosen so that, if a good key 5 is inserted into the channel 6 of the rotor 4, the interface between each rotor pin and the pin of associated stator is located exactly at the interface between the rotor 4 and the stator 7. Under these conditions, the rotor 4 can be rotated manually using the key 5, provided that a mechanism 9 electric lock is him - even in an unlocked state.
- the barrel 2 comprises an additional locking member 10 for preventing the rotor 4 from rotating as a suitable digital code contained in a memory (not shown) housed in the key 5 has not been introduced into a circuit 12 housed in the barrel 2 (on the figure 1 the circuit 12 is disposed outside the barrel 2 to simplify the drawings).
- This circuit 12 when it receives the appropriate code, generates an electric unlock command. For example, it controls the mechanism 9 to enable the unlocking of the rotor 4.
- the code is transmitted from the key 5 to the electronic circuit 12 of the lock via radio relay or via electrical contacts.
- the key 5 is equipped with a transponder and the circuit 12 is equipped with a transponder reader.
- the digital code contained in the memory of the key 5 is transmitted to the circuit 12.
- the circuit 12 compares the transmitted code with at least one prerecorded code in a memory. In case of agreement between the two codes, the circuit 12 generates the electric unlocking command of the mechanism 9.
- the additional locking member 10 is a stator pin which cooperates with a corresponding rotor pin 18 so that if the correct key is inserted into the channel 6, the interface between these two pins is exactly at the interface of the stator 7 and the rotor 4.
- the locking member 10 is extended by a conical stud 20, with rounded apex, which is engaged in a corresponding frustoconical recess 22 formed in the rotor pin 18.
- the member 10 is made of a magnetic material.
- magnetic material denotes a material whose relative magnetic permeability is strictly greater than 1 and, preferably, greater than 100 or 1000.
- the material is a ferromagnetic material such as steel.
- the member 10 is movable between a locking position (represented on the figure 1 ) in which it is engaged with the rotor 4 to block its rotation and a retracted position in which it releases the rotation of the rotor 4.
- the member 10 is slidably mounted in a cylindrical housing 24 which is formed in the stator 7 and which is aligned axially with a housing 26 in the rotor 4 in which slides the pin 18 of the rotor.
- the member 10 further comprises a transverse bar 28 which is formed integrally with the member 10 at the lower end thereof. One end of the bar 28 is shaped to form a heel 29.
- the two sides of the bar 28 are engaged and guided in slots (not shown) formed in the wall of the housing 24. These slots prevent the body locking 10 to rotate when it moves in the cylindrical housing 24.
- Mechanism 9 will now be described in more detail with reference to figures 2 and 3 .
- the mechanism 9 comprises a cavity 32.
- the cavity 32 is a recessed zone disposed inside the stator 7.
- the cavity 32 is located below the housing 24 and receives the bar 28.
- the mechanism 9 comprises a spring 50 adapted to bias the member 10 towards its locking position when the housings 24 and 26 are in facing relation.
- This spring 50 rests, at its lower end, against the bottom of the cavity 32 and at its upper end against the underside of the heel 29 of the member 10.
- the mechanism 9 also comprises a permanent magnet 30 able to radiate a magnetic field.
- the magnet 30 is housed in a compartment of the stator 7 provided for this purpose.
- the magnet 30 is disposed on a support 33 delimiting the lower periphery and the left side of the cavity 32.
- This support 33 is made of a magnetic material, preferably ferromagnetic, so as to channel the flow of the field Magnet radiated by the magnet 30.
- the support 33 has a bend from which extends a horizontal finger 33a and a vertical tooth 33b.
- the finger 33a extends horizontally at the bottom of the cavity 32.
- the distal end of this finger 33a forms a stopper 40, also of magnetic material, preferably ferromagnetic, which extends vertically.
- the stopper 40 is described in more detail with reference to the figure 6 .
- the tooth 33b extends vertically from the bottom of the cavity 32 to the bar 28.
- the cross section of the tooth 33a flares away from its free end towards the bend.
- the magnet 30 is disposed inside the bend of the support 33.
- the mechanism 9 comprises a controllable source 52 of magnetic field capable of reducing or canceling the magnetic field flux of the magnet 30 in the finger 33a.
- the source 52 is a coil wound around the finger 33a.
- the lever 34 is disposed in the cavity 32.
- the lever 34 is in the locking position when the lever 34 is vertical, that is to say it extends mainly along the Y direction.
- 34 is in the unlocking position when it extends in an oblique direction belonging to the plane formed by the X and Y directions. figures 2 and 3 the lever 34 is in the locking position.
- the movement of the lever 34 from its locking position to its unlocking position is achieved by rotation of the lever 34 in the clockwise direction.
- the lever 34 is rotatably mounted on an axis 36.
- the axis 36 is parallel to the direction Z.
- the lever 34 is shaped so that when in the locking position, a game 37a (visible on the figure 3 ) remains between the lever 34 and the bar 28.
- This clearance 37a is large enough to allow the lever 34 to rotate from its locking position to its unlocked position.
- the rotor 4 exerts a force on the member 10 pushing the member 10 to its retracted position.
- the member 10 is slightly moved down.
- the clearance 37a then vanishes and the movement of the member 10 towards its retracted position is prevented.
- the clearance 37a is zero, the lever 34 is immobilized.
- the axis 36 by inverse elastic deformation returns to its initial position in which the lever 34 is not in abutment at the bottom of the cavity 32.
- the arm 38 is in the rest position when it extends substantially vertically. In the rest position, one end of the arm 38 bears on the stopper 40.
- the arm 38 is in the storage position when an upper end 39 of the arm 38 abuts against the heel 29. figures 2 and 3 , the arm is in the rest position.
- the arm 38 is disposed inside the cavity 32.
- the arm 38 is mounted free to rotate on the axis 36.
- the movement of the arm 38 from its rest position to its storage position is effected by a clockwise rotation.
- the arm 38 is shaped so that, when the arm 38 is in its rest position, a game 37b (visible on the figure 2 ) separates the bar 28 from the upper end 39.
- This clearance 37b is larger than the clearance 37a so that even when the lever 34 is blocked by the bar 28 (and therefore the clearance 37a is zero), the game 37b is non-zero.
- the arm 38 can therefore always move to memorize the unlocking order regardless of whether the lever 34 is immobilized or not.
- the arm 38 is made of a magnetic material, preferably ferromagnetic, so as to be displaceable by magnetic forces which create a moment of rotation of the arm 38 about the axis 36.
- the directions and intensities of the magnetic forces which exert on the arm 38 depend in particular on the shape and the thickness of the air gaps between the arm 38 and the magnetic parts in the vicinity.
- the arm 38 is described in more detail with reference to the figure 5 .
- Lever 34 will now be described in more detail with reference to the figure 4 .
- This figure is a sectional view along a sectional plane passing through the lever 34 and the magnet 30.
- the lever 34 is made of a magnetic material, preferably ferromagnetic.
- the magnet 30 and the lever 34 are arranged facing each other so that the magnet 30 constantly urges the lever 34 towards its unlocked position.
- the portion of the lever 34 facing the magnet 30 and the magnet 30 form an air gap 341.
- air gap means the space, typically filled with air, which separates two magnetic pieces vis-à-vis and through which the field lines of a magnetic circuit are looped.
- the "zone of contact” between the two moving magnetic parts with respect to each other is also referred to as “air gap” when they have come into mechanical contact with one another as a result of their displacement.
- the lever 34 is shaped so that the thickness E of the gap 341 decreases as the lever 34 rotates.
- the lower end of the lever 34 forms a foot 342 comprising a bevel 346 vis-à-vis the magnet 30.
- the bevel 346 is inclined so that the distance between the bevel 346 and the magnet 30 decreases as lever 34 rotates clockwise.
- the reluctance of the gap 341 is minimum when the lever 34 is in the unlocking position.
- the lever 34 also comprises a flat 348 disposed on an upper end 350 of the lever 34. This flat 348 forms a stop for the bar 28 opposing the displacement of the member 10 when the lever 34 is in the locking position and the member 10 moves from its locking position to its retracted position.
- the lever 34 further comprises a pin 352 for repositioning the lever 34 which extends from the foot 342 in the direction Z.
- the arm 38 will now be described in more detail with reference to the figure 5 .
- the arch 42 is shaped so that the reluctance of the gap 44 decreases as the arm 38 moves from its rest position to its storage position.
- the shape of the arch 42 is such that the thickness of the air gap 44 decreases as the arm 38 rotates from its rest position to its storage position. Under these conditions, the arm 38 is biased by the magnet 30 to its storage position without energy consumption.
- the arch 42 has a concave face 420 vis-à-vis the magnet 30 and the tooth 33b.
- the profile of the face 420 may be approximated, at first approach, by an arc which extends over an angular portion greater than or equal to 10 degrees and, preferably, greater than or equal to 20, 30, or 40 degrees.
- the position of this arc is, for example, adjusted by the least squares method to minimize the differences between this arc and the actual profile of the face 420.
- the profile of the face 420 It is not strictly an arc since its free end is slightly curved inwards.
- the arm 38 is shaped so that at any point S of the face 420, the center 422 of the osculating circle 424 at this point S is always on the same side of a plane 426 containing the axis 36 and the point S.
- the center 422 does not belong to the plane 426 and is below it in this example.
- the force F1 creates a moment M which can move the arm 38 from its rest position to its storage position.
- the term "moment of a magnetic force” designates the moment of the magnetic force capable of pivoting the arm 38 about the axis 36.
- a condition for a magnetic force exerting a moment on the arm 38 is that this force is directed in a non-intersecting direction with the axis 36.
- the arm 38 is advantageously shaped so that the thickness of the air gap 45 also decreases as the arm 38 moves from its rest position to its storage position.
- the arm 38 further comprises a stop 51 adapted to hold the lever 34 in the locking position against the bias exerted by the magnet 30 when the arm 38 is in the rest position.
- the stop 51 is a projection disposed on the arch 42.
- the stop 51 extends radially on the inner radius of the arch 42.
- the figure 6 represents the arm 38 in its rest position. In the rest position, a rear end 41 of the arch 42 is in abutment against the stopper 40.
- the stopper 40 prevents the rotation of the arm 38 in the opposite direction of clockwise.
- the stopper 40 is beveled so as to maximize the magnetic force exerted between the stopper 40 and the end 41.
- the stopper 40 forms with the end 41 an air gap 46 through which loops a magnetic circuit C2 connecting the two opposite poles of the magnet 30.
- This magnetic circuit C2 passes successively through the finger 33a, the gap 41, the arch 42 and the gap 45.
- the reluctance of the gap 46 is minimized when the arm 38 is in the rest position.
- the arm 38 and the support 33 are shaped so that when the arm 38 is in the rest position, the reluctance of the gap 46 is less than the reluctance of the gap 44.
- F2 denotes the magnetic force exerted by the magnetic circuit C2 on the arm 38.
- the figure 7 represents the arm 38 turning from its rest position to its storage position. In this position, the reluctance of the gap 44 is smaller than the reluctance of the gap 46.
- the figure 8 represents the arm 38 in the storage position.
- the upper end 39 of the arm 38 and the heel 29 form an air gap 48 through which loops a third magnetic circuit C3 which connects the two opposite poles of the magnet 30.
- This circuit C3 passes successively through the gap 45, the arch 42, the arm 36, the gap 45, the bar 28 and the tooth 33b.
- the end 39 and the heel 29 are shaped so that when the arm 38 is in its storage position, the reluctance of the gap 48 is less than the reluctance of the gaps 44 and 46.
- the end 39 is in abutment against the heel 29 when the arm 38 is in its storage position.
- F3 denotes the magnetic force exerted by the magnetic circuit C3 on the arm 38.
- the lock is in a locked state.
- the housings 24 and 26 are vis-à-vis and the member 10 is in its blocking position.
- the arm 38 is in the rest position ( figure 6 ).
- the gap 46 being thinner than the air gaps 44 and 48, the moment of the magnetic force F2 is stronger than the moment of the magnetic forces F1 and F3.
- this moment of the magnetic force F2 urges the arm 38 counter-clockwise. The arm 38 is thus held against the stopper 40.
- lever 34 is held in its locking position via the stop 51 and the stud 352.
- a user enters the key 5 in the channel 6 of the lock.
- the circuit 12 reads the digital code carried by the key 5. If this digital code is wrong, the mechanism 9 remains in the locked state.
- the member 10 sinks into the housing 24 until the clearance 37a vanishes.
- the member 10 is then in abutment against the lever 34.
- the member 10 can not reach its retracted position, the rotor 4 can not rotate and the lock remains in the locked state. The lock therefore returns to step 60.
- an unlocking command of the mechanism 9 is generated during a step 64.
- an electric pulse is generated at the terminals of the source 52.
- the source 52 then radiates an electromagnetic field that is withdrawn from the permanent magnetic field of the magnet 30 in the finger 33a. .
- the source 52 cancels the flux of the magnetic field in the finger 33a.
- the intensity of the magnetic flux in the gap 46 becomes less than the intensity of the magnetic flux in the gap 44.
- the moment of the magnetic force F1 becomes stronger than that of the force F2.
- the moment of the magnetic force F1 then triggers the movement of the arm 38 from its rest position to its storage position ( figure 7 ).
- the source 52 is no longer energized since the conformation of the arm 38 in the arch allows the arm 38 to turn to its storage position without power consumption.
- the duration of the pulse is determined so that the supply of the source 52 is completed at a time when the arm 38 has already turned enough so that the moment of the force F1 is stronger than that of the force F2.
- the lever 34 is immobilized by the member 10 at the moment when the unlocking command is generated. Under these conditions, the arm 38 stores the order by positioning itself in its storage position. Once the lever 34 is no longer immobilized, for example because the user puts the key back so that the rotor 4 no longer exerts a force on the member 10, the lever 34 is biased to its unlocking position by the magnet 30. The mechanism 9 is unlocked.
- a step 66 the user rotates the rotor 4 in the stator 7 by means of the key 5.
- the rotation of the rotor 4 causes the displacement member 10 to move in its retracted position. 10 is no longer blocked by the lever 34.
- the lock is then unlocked.
- a step 68 the user locks the lock.
- the user repositioned the rotor 4 in the stator 7 by means of the key 5 so that the housings 24 and 26 are vis-à-vis.
- the member 10 is then biased by the spring 50 from its retracted position to its locking position.
- the arm 38 is returned from its storage position to its rest position via the heel 29 which goes up.
- the lever 34 is returned from its unlocking position to its locking position via the projection 51 and the stud 352.
- the lock then returns to the locked state.
- the figure 10 illustrates a locking mechanism 100 identical to the mechanism 9 except that the support 33 is replaced by a support 102.
- This support 102 is identical to the support 33 except that the tooth 33b is replaced by a tooth 102b.
- the arch 42 of the arm 38 and the tooth 102b form an air gap 104.
- the tooth 102b is shaped so that the surface of the face of the arch 42 vis-à-vis the tooth 102b increases as and when as the arm 38 rotates from its rest position to its storage position.
- the cross section of the tooth 102b flares, in the direction Z, from the elbow to the free end of the tooth 102b.
- the surface of the air gap 104 increases in a direction parallel to the axis of rotation of the arm, and therefore its reluctance decreases, as the arm 38 rotates to its storage position. In this embodiment, it is therefore no longer necessary for the thickness of the gap 104 to decrease as the arm 38 rotates.
- the figure 11 illustrates a locking mechanism 80 identical to the locking mechanism 9 with the exception that the magnet 30 is replaced by a permanent magnet 82 disposed on the arch 42.
- the support 33 is replaced by a support 84 identical to the support 33 with the exception that the tooth 33b is replaced by a tooth 84b.
- This tooth 84b is shaped so that when the arm 38 moves from its rest position to its storage position the thickness of an air gap 86 formed by the magnet 30 and the tooth 84b vis-à-vis decreases.
- the figure 12 illustrates a locking mechanism 90 identical to the locking mechanism 80 except that the storage arm 38 is replaced by a storage arm 92 in which the arch 42 is omitted.
- the magnet 82 is replaced by a magnet 95 disposed on an end 93 of the arm 92.
- the support 84 is replaced by a support 94 which is shaped so that the face of this support 94 facing the magnet 95 forms a hoop 97.
- the hoop 97 is shaped so that when the arm moves from its rest position to its storage position, the thickness of an air gap 99 formed by the magnet 95 and the face of the hoop 97 in vis-à-vis the magnet 95 decreases.
- Other holding mechanisms may be used in addition or in replacement to keep the arm in its rest position and / or in its storage position.
- magnets or springs may be used.
- the foot of the locking lever can be in the form of an arch.
- the stator lock member 10 is not necessarily magnetic material. It can be plastic.
- the space of the arm 38 between the axis 36 and the inner radius of the arch 42 is full.
- the magnet and the hoop may be shaped so that the thickness of the gap formed by the magnet and the hoop is constant or increases during rotation of the arm to the storage position.

- Elektronisches Schloss, das dazu bestimmt ist, von einem Schlüssel gesteuert zu werden, der elektronische Einrichtungen aufweist, um die Entriegelung des Schlosses zu steuern, wobei das Schloss aufweist:- einen Stator (7) und einen Rotor (4), der im Stator (7) drehbar montiert und mit einem Kanal (6) versehen ist, in den der Schlüssel eingeführt werden kann,- ein Organ (10) zum Blockieren des Rotors, das in einer Aufnahme des Stators zwischen einer Blockierstellung, in der es mit dem Rotor (4) in Eingriff ist, um seine Drehung zu blockieren, und einer eingezogenen Stellung verschiebbar ist, in der es die Drehung des Rotors (4) freigibt,- einen Verriegelungshebel (34), der als Reaktion auf einen elektrischen Entriegelungsbefehl zwischen einer Verriegelungsstellung, in der der Verriegelungshebel vom Blockierorgan (10) arretiert werden kann, um sich seiner Verschiebung ausgehend von seiner Blockierstellung zu widersetzen, und einer Entriegelungsstellung verschiebbar ist, in der das Blockierorgan (10) frei ist, um seine Blockierstellung zu verlassen, und- einen Speicherarm (38) aus Magnetmaterial, der als Reaktion auf den elektrischen Entriegelungsbefehl zwischen einer Ruhestellung und einer Speicherstellung um eine Achse (36) drehen kann, selbst wenn der Verriegelungshebel (34) vom Blockierorgan (10) arretiert wird,dadurch gekennzeichnet, dass:- das Schloss mindestens einen am Stator (7) oder am Speicherarm (38) befestigten Magnet (30) aufweist, um den Speicherarm (38) von seiner Ruhestellung in seine Speicherstellung zu verschieben,- der eine, entweder der Stator (7) oder der Speicherarm (38), einen Bügel (42) aus Magnetmaterial und der andere, entweder der Stator (7) oder der Arm (38), einen Magnetzahn (33b) gegenüber dem Bügel (42) aufweist, um einen ersten Magnetspalt (44) zu erzeugen, über den sich ein erster Magnetkreis (C1) schließt, der zwei entgegengesetzte Pole des Magnets (30) verbindet, wobei der Finger (33b) und der Bügel (42) so gestaltet sind, dass:• die Dicke des ersten Magnetspalts (44) nach und nach abnimmt, wenn der Speicherarm (38) sich von seiner Ruhestellung in seine Speicherstellung dreht, und/oder• die Oberfläche der Seiten des Bügels (42) und des gegenüberliegenden Zahns (33b) in einer Richtung parallel zur Drehachse nach und nach zunimmt, wenn der Arm (38) sich von seiner Ruhestellung in seine Speicherstellung dreht.
- Schloss nach Anspruch 1, wobei der Stator (7) ebenfalls einen Finger (33a) aus Magnetmaterial aufweist, der einen zweiten Magnetkreis (C2) erzeugt, welcher die zwei entgegengesetzten Pole des gleichen Magnets (30) verbindet, indem er über den Speicherarm (38) und einen zweiten Magnetspalt (46) zwischen dem Speicherarm (38) und einem Ende des Fingers (33a) geht, wobei der Speicherarm (38) und das Ende des Fingers (33a) so gestaltet sind, dass der magnetische Widerstand des zweiten Magnetspalts (46) geringer als derjenige des ersten Magnetspalts (44) ist, wenn der Speicherarm in seiner Ruhestellung ist.
- Schloss nach einem der vorhergehenden Ansprüche, wobei das Blockierorgan (10) ein Magnetbauteil aufweist, das einen dritten Magnetkreis (C3) erzeugt, der die zwei entgegengesetzten Pole des gleichen Magnets (30) verbindet, indem er über den Speicherarm (38) und einen dritten Magnetspalt (48) zwischen dem Arm (38) und dem Magnetbauteil des Blockierorgans (10) geht, wobei der Speicherarm (38) und das Magnetbauteil so gestaltet sind, dass der magnetische Widerstand des dritten Magnetspalts (48) geringer als derjenige des ersten Magnetspalts (44) ist, wenn der Speicherarm (38) in seiner Speicherstellung ist.
- Schloss nach Anspruch 2, wobei das Schloss eine steuerbare Magnetfeldquelle (52) aufweist, die den Fluss des Magnetfelds innerhalb des Fingers (33a) aus Magnetmaterial ausreichend verringern kann, damit die Stärke des Magnetfelds im zweiten Magnetspalt (46) geringer als die Stärke des Magnetfelds im ersten Magnetspalt (44) ist, um die Drehung des Speicherarms (38) von seiner Ruhestellung in seine Speicherstellung als Reaktion auf den Entriegelungsbefehl auszulösen.
- Schloss nach einem der vorhergehenden Ansprüche, wobei der Verriegelungshebel (34) aus magnetischem Material hergestellt und so gestaltet ist, dass der Dauermagnet (30) durchgehend den Hebel (34) in seine Entriegelungsstellung beaufschlagt.
- Schloss nach Anspruch 5, wobei der Speicherarm (38) einen Anschlag (51) enthält, der den Verriegelungshebel (34) gegen die vom Dauermagnet (30) ausgeübte Beaufschlagung in der Verriegelungsstellung halten kann, wenn der Speicherarm (38) in seiner Ruhestellung ist.
- Schloss nach einem der vorhergehenden Ansprüche, wobei an jedem Punkt S der Seite (420) des Bügels (42) gegenüber dem Magnetzahn (33b) die Mitte des Schmiegkreises (424) an diesem Punkt S sich immer auf der gleichen Seite einer Ebene (426) befindet, die die Drehachse (36) des Speicherarms (38) und diesen Punkt S enthält.
- Schloss nach einem der vorhergehenden Ansprüche, wobei der Bügel (42) sich über einen Winkelabschnitt größer als oder gleich 10 Grad erstreckt.
- Schloss nach einem der vorhergehenden Ansprüche, wobei der Arm (38) gegen einen Anschlag (40) aufliegt, wenn der Arm (38) in seiner Ruhestellung ist, und/oder der Arm (38) gegen einen Absatz (29) des Blockierorgans (10) aufliegt, wenn der Arm (38) in seiner Speicherstellung ist.
- Schloss nach einem der vorhergehenden Ansprüche, wobei der Magnet (30) und der Arm (38) einen vierten Magnetspalt (45) formen, wobei der Arm (38) und der Magnet (30) so gestaltet sind, dass die Dicke des Magnetspalts (45) in dem Maße abnimmt, in dem der Arm (38) sich von seiner Ruhestellung in seine Speicherstellung verschiebt.
