Magnetically operated control device

pie invention relates to a magnetically actuated control device with a cylinder rotatably mounted in a housing, a j _:

slide axially displaceable and non-rotatably arranged in the cylinder, forth between a for coupling with a locking member the | iienden coupling position and one uncoupling position is displaceable, at least one magnet rotatably mounted within the cylinder; rotor, which normally blocks the slide from moving and '

! ι

«By means of an appropriately coded, insert it into a key channel bar magnetic key can be rotated into a price position in which the slide can be shifted from the uncoupling position into the

Coupling position allows.

In a known control device of this kind, which is designed as a lock (Fig. 3 in DT-OS 1,553,364), the key channel formed m% slide. The slide is provided with a face plate facing the outside of the lock, on whose side facing the inside of the lock axially extending pins are arranged which, in the coupling position, are in bores of the rotatably mounted coupling member

are insertable. On the side of the face plate facing the lock interior, a pin is also attached, which is in the release position of the magnet rotor can dip into a groove of the magnet rotor formed on the circumference of the rotor, whereupon the entire slide can be moved into its coupling position. The slide is moved with the help of the magnetic key, which is secured by means of a Stop on the face plate of the slide.

The lock is opened in two stages, so to speak. First the key is inserted into the key channel, |

whereupon the magnet rotor moves into its release position. Afterward the slide is brought into its coupling position by further pushing in the magnetic key. This type of operation j

it lacks a certain ease of use. Each is more important but that the lock may be opened by the use of force,

j i.e. by forcing the face plate into the lock- i

inner, can be pressed.

The invention is based on the object of a magnetically actuated! to train a bare control device of the type specified above, that the coupling of the slide with the locking member is mechanical takes place regardless of the key.

This object is achieved according to the invention in that the slide is biased by a spring in the direction of its coupling position and that the key channel is arranged separately from the slide

509 8 15/0229

In this way, the slide can be mechanically independent of the key isel can be moved into its coupling position by the spring. The J

i - i

[The key therefore only has a control function (i.e. serves

I I

! only to adjust the magnet rotor), while the mechanical ^ ! j

Locking function, ie moving the slider from the ^! ! Spring is taken over. This not only facilitates the operation, but above all increases the security of the lock against the use of force. By forcing the key in, namely, the slide cannot be coupled to the locking member, and if the wrong key is forcibly turned it will turn
the cylinder only goes through freely.

The control device according to the invention is used in particular as a lock
used, but can also be used as a control device for controlling machine parts and the like.

A preferred embodiment of the invention is marked by ', characterized in that the slide has a coupling claw _t in
the coupling position of the slide in a coupling groove of the Verrie-] gelungsorgans engages, and in that the coupling jaw in the position with Sntkupplungs tapered surfaces slightly in the coupling groove of the locking member protrudes, so that during a relative movement between! i / locking member and slide the slide is displaced by a corresponding amount against the biasing force of the spring to allow fine free rotation of the magnet rotor zn . So if the
ßylinder is turned with the help of the inserted key, can
the magnetic rotor under the action of the magnetic forces of the magnetic key in _._

509815/0229

get its release position, whereupon the spring the coupling '■

slide moved into its coupling position.

To move the heavy back into its uncoupling position after pressing the lock to move back, is in a further embodiment of the | Invention in the key channel a leaf spring connected to the slide arranged, which protrudes when the key is inserted with a nose j into a recess of the key, so that when removed;

ι the key of the slide against the force of the slide

biasing spring is taken into its uncoupling position.

Appropriately, several magnet rotors are assigned to the slide, whereby the locking options are increased accordingly.

The locking function of the magnet rotor or the magnet rotors can be on can be done in two fundamentally different ways. One embodiment is characterized in that the magnet rotor is immovable and about one perpendicular to the direction of movement of the SchiäDer extending axis is rotatably arranged in the cylinder, and that the slide has a pin protruding into the plane of the magnet rotor which can be inserted in the release cell of the magnet rotor into a groove formed on the circumference of the magnet rotor and into the locked position rests on the circumference of the magnet rotor.

The other embodiment is characterized in that the Magnet rotor ^ m slide around a perpendicular to the slide direction of movement extending axis is rotatably mounted andinit a

-5-

509815/0229

is provided laterally projecting pin which in the ^blocking: present position of the magnetic rotor to a cylindrical fixed transverse wall

and in the release position through a passage opening of the . Transverse wall can be passed through.

In the last-mentioned embodiment, the transverse wall expediently has the shape of a to the circumference of the magnet rotor- » the semicircle, on whose mean radius on the outer circumference the; Passage opening is formed.

There is a particular advantage of the training according to the invention in that the possibility is created of two or more slides with associated magnet rotor in the cylinder parallel to one another to be provided, which can either be operated independently of one another or mechanically connected to one another. The sliders can in this case are arranged on both sides of the key channel and / or next to one another on the same side of the key channel.

If the various slides can be operated independently of one another, the control device is suitable as a lock; ; for a main locking system in which one slide can be operated by the master key suitable for a large number of locks and the other slide can be operated by the special key. In '■ this case, the lock ie by means of two different keys (the master key and the special key) is operated.

^: ι

By mechanically connecting the slide, on the other hand, the lock is created

509815/0229

can only be operated with a single key. In this case who-i by using several sliders and one accordingly; increased number of magnet rotors, the locking variants enlarged in any way, the lock nevertheless relatively can have small dimensions.

Another embodiment of the invention, in which the locking member is designed as a rotatable bolt and the axis of rotation

is

of the cylinder is aligned with the axis of rotation of the bolt, / characterized that mirror symmetry on both sides of the locking member each one marked in the manner described above Cylinder is provided. Such a control device is suitable, for example, as a door lock that can be operated from both sides the door must be able to be operated.

ι I

! The control device shown in Fig. 1, for example as |

: The door lock can be used, has a housing 2 in which a locking member 4 in the form of a bolt with a bolt projection; 6 is rotatably mounted. On both sides of the locking organ is in the \

Housing 2 a cylinder unit 8 or Io arranged through

t a key 12 or 14 equipped with magnets can be actuated. j The two cylinder units 3 and Io are designed in the same way,
only one of the two cylinder units, namely the
left cylinder unit 8 needs to be described.

The cylinder unit 8 has a cylinder 15 which is around a
to the axis of the locking member 4 aligned axis is rotatable.
A key channel 13 is located in the cylinder 15 parallel to the axis of rotation

formed, in which the dashed indicated key Io is introduced
bar-i Separate from the keyway, but running parallel to the

Key channel is formed in the cylinder 15, a chamber 19 in which
a slide 16 is displaceable in the axial direction between a decoupling position and a coupling position. The slider 16
; is supported by a spring 17 fixed to the cylinder in the direction of
pretensioned its uncoupling position.

The slide 16 carries two magnetic rotors 18,2o, each around j

j

an axis perpendicular to the cylinder axis can be rotated. ; Each of the two magnet rotors I8,2o has a front | standing pin 21 or 22, which when not inserted!

509815/0229

.Magnet key an eccentric position, for example the dashed one Position 21 "or 22" occupies. The pin lies in this position 21 and 22 on a cylindrical transverse wall 24 and 26, respectively. The transverse wall 24 or 26 has the shape of a semicircle in the plane of the drawing, whose radius corresponds to that of the magnet rotors 18 or 2o * The pins 21 and 22 can thus be practically in any position of the i

Magnet rotors 18 and 2o by the spring 17 against the transverse ^wall: are pressed, j comparable whereby displacement of the slider 16 is prevented. In the middle of the transverse wall 24 or 26, a passage opening 27 or 28 is formed, through which the pin 21 or 22 can pass when it assumes the position shown in FIG. The magnet rotors 18, 20 are magnetized in such a way that, when the appropriate magnetic key 12 is inserted, they are just moved into such a position that the pins 21 and 22 are aligned with the passage openings 27, 28. The slide 16 can thus be pushed to the right into its coupling position under the action of the spring 17.

At its (in the figure) right end of the Sdaieber 16 is with a Coupling claw 3o provided in the form of a projection, which in the coupling position in a coupling groove 32 of the with several such Fcupplungsnuten provided locking member 4 engages. The coupling claw 3o faces the locking member 4 on its side Side provided with laterally beveled surfaces 34. Therefore, when the cylinder 15 with the help of the magnetic key 12 relative to the locking member 4 is rotated, the beveled surface 34 slides on the edge of the coupling groove 32, whereby the slide 16 is

-9-

509815/0229

(against the spring 17 by a small amount to the left (in Fig. 1) is moved. This shift is sufficient to the pin 21,22 of

[to solve the transverse walls 24,26, whereupon the magnet rotors are below the action of the magnets of the magnetic key can move into their release position.

The operation of the lock shown in Figures 1 and 2 is as follows. Take it in the locked state (with the key removed) the rotors assume a position as indicated, for example, by the dotted pins 21 or 22. Be in this position the pin 21 or 22 pressed by the spring 17 against the inner surface of the transverse walls 24 or 26 »Due to the geometric The configuration of the forces acting on the magnet rotors (bearing forces and supporting forces of the journals) "braced" to a certain extent the magnet rotor with the bulkhead ,, and the slide is in held in its portrayed position «,

To operate the lock, the magnetic key 12 is inserted into the keyway 13 and turned on the same side in the opening direction. When turning, the inclined surface 34 of the coupling claw 3o slides on the outer edge of the coupling groove 32 of the locking mechanism 4, whereby the slide is displaced to the left against the force of the spring 12 '. The pins 21, 22 of the magnet rotors disengage from the transverse walls 24, 26. The magnetic forces of the correspondingly coded magnetic key 12 then turn the magnetic rotors into their release position (solid lines in FIG. 1), in which they with the passage openings 24, 28

the transverse walls are aligned. If the coupling claw 3o when turning further of the key is opposite a coupling groove 32, the spring 17 can then move the coupling slide to the right, whereupon the slide 16 and thus the cylinder 15 is coupled to the locking element 4.

around the slide 16 when removing the key back into his To move the uncoupling position, the slide 16 is a leaf spring 38 connected, which is depressed when the key 12 is inserted and then with a nose in a locking groove 36 of the key jumps. The force of the leaf spring 38 is such that when the key is removed, the slide counteracts the force the spring 17 is carried along and the nose of the plate spring 38 only emerges from the locking groove 36 when the slide reaches its left end position (in. Fig. I) has reached.

If the wrong key is inserted in the lock in the uncoupled position introduced, so the magnet rotors can not be in tre release position move / and twisting the key only has a free running of the cylinder (without entrainment of the locking member) result. Also a forceful impression of a wrong one Key cannot engage the clutch, d? the key channel is arranged separately in front of the chamber of the slide.

The embodiment shown in FIGS. 3 and 4 corresponds in its basic structure of the embodiment shown in Fig. 1, and corresponding components were made with the same

509815/0 2 29

! Provided with reference symbols. The two exemplary embodiments differ

which is essentially only through the training of the blocking of the

J Magnetic rotors. While in the first-mentioned embodiment the magnet rotors are attached to the slide, the magnet rotors 18 of FIGS. 3 and 4 arranged immovably in the cylinder. The magnetic rotors are provided with locking grooves 4o, which are provided with pins 42 ! cooperate, which are attached to the webs of the slide 16.

A shift of the slide wM blocked by the fact that the pin 42 attack the outer circumference of the magnet rotors 18. When the magnetic rotors 18 by the magnetic key 12 in their release position have been moved (left half of FIG. 3), the pins 42 connected to the slide can be inserted into the grooves 4o of the magnet rotors immerse so that the coupling claw 3o of the slide can engage in a groove 32 of the locking member 4.

In the embodiment shown only schematically in FIGS. 5 and 6, two key channels 13 ', 13 ·' \ are provided, one on top of the other, to which a total of four slide units 8 ', 8'', O ¹¹¹ and; B ^{1111 are} assigned. The slide units are on opposite

lying sides (to the right and left of the keyway in Fig. 5); Arranged. |

pie slide units 8 'to 8 ¹¹¹¹ can either be mechanically connected to one another or can also be operated independently of one another. In the first case, the magnetic key must have so many

Wear magnets as required to operate all of the cylinder units. 6 shows three such magnets on the upper key half 12 ″, whereas the lower side 12 ′ is magnetized or not magnetized depending on the application. The upper and lower side of the two key halves 12 ′ and 12 ″ are separated by a slot 52 , which can of course also be omitted for optical reasons if the two key channels 13 'and 13 "are combined to form a common key channel. The magnetization can also take place by means of the individual magnets 46, 48, 50 or also by means of a magnetic strip 54 indicated by dashed lines. As already mentioned, the slide units 8 * to 8 ^{1111 can} each be actuated individually or can be connected to one another in any combination. With individual mounting, the control device can be used as a lock for a general locking system, in which the lock can be operated by means of a master key suitable for all locks and by means of a special key. Here too, for example, the two slide units 8 ′ and 8 ′ ^{111 on the left} and the two slide units 8 ¹¹ and 8 ^{1111 on the right could be} coupled. When all slide units are coupled, you get exceptionally high locking variants.
