Definitions
- the invention relates to a locking device, in particular for locking a box provided with a flap, which comprises a housing with a housing core and at least one locking element which is released by an unlocking means from a locking position in which the housing core is immobile into an unlocking position in which the Housing core is movable relative to the housing, can be brought.
- Letter box locks are known from the prior art, for example, which have a locking cylinder with a cylindrical locking cylinder core.
- spring-mounted, multi-part frame-like or pin-shaped locking elements are moved into an unlocked position and the lock cylinder core can be rotated relative to the housing by rotating the key.
- This rotation causes a locking bolt that is firmly connected to the core to be pivoted into an unlocking position and the flap can be opened.
- the key must be turned 90 to 180 degrees.
- Rotatable handles for opening doors, windows or flaps are also known from the prior art, which have a locking cylinder with a cylindrical locking cylinder core.
- the locking cylinder is used to block a rotary movement of the handle, which prevents unauthorized opening of the door, window or flap.
- resiliently mounted, multi-part frame-like or pin-shaped locking elements are moved into an unlocked position and the lock cylinder core can be rotated relative to the rotatable handle by rotating the key.
- This rotation causes a locking bolt which is firmly connected to the core to be pivoted into an unlocking position and the handle can be rotated.
- the door, the window or the flap can be opened.
- the key must be turned 90 to 180 degrees.
- the present invention has for its object to provide a locking device of the type mentioned that enables a very simple unlocking. Furthermore, the invention has for its object to provide a locking device which can be attached completely inside a box to be locked with a flap.
- the object is achieved in that a linear movement of the unlocking means causes an unlocking means to be actuated.
- a suitable unlocking means is required to unlock the locking device.
- a key can be inserted into a receiving channel of the locking device according to the invention in order to move the locking elements into the unlocked position.
- a further linear movement of the key actuates an unlocking means, whereby the locking device is unlocked.
- a flap of a mailbox or another container closed with a flap, for example a cupboard or a locker, can be opened or a rotary movement of a handle for an opening, in particular a window, can be released.
- a rotational movement of the unlocking means is advantageously not required for unlocking.
- the locking device according to the invention can advantageously be fitted completely inside the box or a rotatable window handle. It is not necessary to pass a locking cylinder, for example, through a flap of a box to be locked or a rotatable handle, a slot in the flap or the rotatable handle is sufficient for inserting an unlocking means.
- an actuating element can be moved linearly, rotated or pivoted and / or moved vertically, obliquely, parallel or coaxially to a direction of movement of the unlocking means.
- the linear insertion movement of the unlocking means which can be an insertion movement of a key, is translated into a linear movement, a rotary movement or a pivoting movement of the actuating element.
- a long stroke or rotation of the unlocking means from a locking position into an unlocking position is advantageously possible from a short insertion path of the unlocking means.
- the actuator can also be set up to form a material, non-positive and / or positive connection with the unlocking means, which may have a locking bolt.
- the housing core has a shape deviating from a cylindrical shape and in particular comprises a rectangular base area.
- the fact that no rotational movement of the housing core is required for unlocking means that freedom of design is advantageously increased.
- a housing core with a rectangular base area can also be guided more stably in a housing and is secured against tilting.
- An actuating element is expediently attached to the housing core, preferably on an end face facing the unlocking means, and in particular is formed in one piece. It is also conceivable that the actuating element is formed from a different material and / or has different mechanical properties than the housing core. Simple manufacture is advantageously possible.
- the unlocking means has a movable locking bolt, which is preferably linearly movable or pivotable.
- the locking bolt is set up to engage behind a locking projection. If the locking bar can be moved linearly, it could be extended and retracted to engage behind the locking projection, which can be a frame section of a letter box housing. A very compact design is advantageously possible. A drive-in path of 3 to 10 mm can be sufficient to achieve a particularly burglar-proof locking.
- the locking bolt can also be formed from a flat piece of metal which engages behind the locking projection in a locking position and can be pivoted into an unlocking position. A movement of the locking bolt perpendicular, parallel, coaxial or oblique to the linear direction of movement of the unlocking means is conceivable.
- the housing core is formed in several parts, a first housing core part being designed to receive the unlocking means, in particular a key, and in particular being cylindrical. If the housing core is constructed in several parts, the linear movement of the unlocking means can advantageously be translated into a different type of movement of further housing core parts.
- the multi-part housing core acts like a gear and converts a linear movement, for example, into a rotary movement of further housing core parts.
- a second housing core part is designed like a sleeve, at least partially surrounds the first housing core part and can be rotated about a longitudinal axis.
- a linear movement of the first housing core part which can be provided for receiving the unlocking means, can advantageously be converted into a rotary movement of the second housing core part about a longitudinal axis. If an actuating element is attached to the second housing core part, an actuation path or angle to be covered in the circumferential direction can be determined by its eccentric attachment.
- a second housing core part expediently has a groove into which a driver element protruding from the first housing core part in the direction of the second housing core part engages.
- Both housing core parts are preferably cylindrical and coaxial with one another.
- a linear movement of the first housing core part can advantageously be converted into a rotary movement of the second housing core part by the driver element, which can be designed in particular as a driver pin.
- the groove can have a directional component that runs predominantly in the circumferential direction.
- the groove can have a directional component that runs predominantly in one insertion direction.
- a path that the driver element travels in the longitudinal direction is preferably as long as a path in the circumferential direction.
- a first housing core part of a multi-part housing core can be moved linearly in the unlocked position and a second housing core part, which surrounds the first housing core part like a sleeve, can be rotated in the unlocked position.
- the linear movement can be brought about by a suitable key which is inserted into the first housing part and moves further in an insertion direction, in particular is inserted.
- a linear movement of the first housing core part can advantageously be translated into a rotary movement of the second housing core part.
- a restoring means which preferably has a helical spring and which is arranged between a housing and a one-piece housing core or between a first housing core part and a second housing core part of a multi-part housing core.
- a linear movement of the housing core or the first part of the housing core when unlocking the locking device takes place against a restoring force of the restoring means.
- an unlocking means for use with the locking device comprises an electronic key, on which data are stored, which are transmitted to a control unit, which is set up to control at least one preferably electric drive, which is used to move the locking elements into an unlocked position and to linearly move a housing core or a first housing core part of a multi-part housing is provided.
- the control unit checks whether the data on the electronic key, which can have an RFID chip, authorize the device to be unlocked. If this is the case, the locking elements are moved into the unlocked position and the housing core or a first housing core part of a multi-part housing core is moved linearly into a housing.
- an unlocking means which comprises in particular a preferably linearly movable locking bolt or a multi-part locking element, is arranged inside the housing or within a receiving section molded onto the housing.
- the multi-part locking element is preferably formed in two parts and can be set up to engage behind a locking pin.
- two semicircular ring sections can be provided.
- the receiving section can be provided for receiving a locking pin which dips into the receiving section and can also be designed as a sleeve section.
- the unlocking means is advantageously protected against contamination by the housing or the receiving section.
- an unlocking means is provided, which is arranged both in an unlocking position and in a locking position within the housing or within a receiving section molded onto the housing.
- Two reset means are expediently provided, of which a first between a housing and a one-part housing core or between a first housing core part and a second housing core part of a multi-part housing core is arranged, and a second between the housing and an unlocking means.
- the restoring means can be designed, for example, as coil springs.
- a purely mechanical actuation of the locking device is possible. Battery-operated electrical or electronic components that require current are not required.
- the locking device is advantageously particularly fail-safe.
- the unlocking means engages in an locking position in an annular groove of a locking means or engages behind a retaining projection of a locking means.
- the locking means is preferably designed as a locking pin which is fixedly connected to a container inner wall or a flap of the container.
- the at least one locking element is expediently pin-shaped, rod-shaped or frame-like and is preferably held in the locking position by a restoring means, in particular a spring.
- a frame-like design is particularly advantageous since the production of frame-like locking elements is particularly simple. In addition, such locking elements are easier to handle during assembly.
- the housing has a viewing window through which a position of a connecting means that connects a first housing core part to a second housing core part of a multi-part housing can be recognized.
- a user of the locking device can advantageously recognize from the position of the connecting means whether the device is locked or unlocked.
- the connecting means can be a driver pin, which is inserted with a first end section into an opening in the first housing core part and engages with a second end section into a groove in the second housing core part.
- Locking device (1) shown in an exploded view comprises a housing (2) which is set up to receive a housing core (5) having two parts (3, 4).
- a first cylindrical housing core part (3) has an elongated channel, which is closed on one end face (6), for receiving a key (7). Openings (9) are made in an upper side (8) of the first housing core part (3), through which locking sections (10) of frame-like locking elements (11) can pass.
- the locking elements (11) engage with the locking sections (10) in a locking position, in which the first part (3) is arranged immovably in relation to the housing (2) and / or the second housing core part (4)
- Fig. 1a not visible receiving recesses which are made in an inside of a second housing core part (4).
- the second housing core part (4) is designed like a sleeve, surrounds the first housing core part (3) and is arranged rotatably about a longitudinal axis between the first housing core part (3) and the housing (2).
- the locking elements (11) are mounted in the first part (3) on coil springs (12), each of the coil springs (12) having an underside (13) against one in Fig. 1a Not shown receiving portion of the first housing core part (3) and with an upper side (14) against a projection (15) of one of the frame-like locking elements (11).
- the locking sections (10) pass through the openings (9) and are in the locked position.
- a suitable key (7) is inserted into the channel of the first part (3) for unlocking, ie for moving the locking elements (11) from a locking position into an unlocking position.
- the locking sections (10) of the locking elements (11) are moved against the spring force of the coil springs (12) through the openings (9) into the interior of the first housing core part (3).
- the first housing core part (3) can be moved linearly relative to the second housing core part (4) in the direction of a key insertion direction.
- driver pin (16) which is preferably formed from a metal and which, with a pin head (17), extends longitudinally and Groove (18) which extends in the circumferential direction engages in the second part (4).
- the groove (18) is continuous in the radial direction of the cylindrical sleeve.
- first housing core part (3) is moved linearly into the second housing core part (4) in the unlocked position of the locking elements (11) by pressing the key in its axial direction, this linear movement causes a straight movement of the driver pin (16) from an initial position in which it bears against a first groove end (19), in an end position in which the driver pin (16) bears against a second groove end (20).
- the second part (4) is rotated by an actuation angle with respect to the first part (3). In this exemplary embodiment, this is 90 degrees, since the first (19) and the second groove end (20) are offset from one another by an angle of 90 degrees in the circumferential direction of the cylindrical second part (4).
- an insertion path by which the first part (3) is pushed into the second part (4) is the same size as a path in the circumferential direction by which the second part is rotated. A particularly good translation of a linear movement into a rotary movement is thereby achieved.
- the second housing core part (4) is provided on the outside with an actuating element (21) which protrudes from the housing (2) and to which an unlocking means (23) in the form of a locking bolt is attached by a fastening clamp (22) the bolt (23) is rotated by the actuation angle of 90 degrees from a basic position into an unlocking position when the second housing core part (4) is rotated.
- actuation angles are conceivable, for example between 30 and 90 degrees, in particular 30, 45 and 60 degrees.
- a locking device (1) shown in a side view has a suitable key (7) inserted into the first part (3) of the housing core (5) to such an extent that the locking mechanism shown in Fig. 1a shown locking elements (11) are in the unlocked position.
- the locking bolt (23) extends in Fig. 1b into the drawing plane. If the key (7) is linear in a key path, which can be between 5 and 15 mm, preferably 8 mm, in one Fig. 1c pushed end position, a linear movement of the first part (3) of the housing core (5) is effected, which leads to a rotation of the sleeve-like second part (4) by the actuating pin (16) by the actuation angle. As a result, the bolt (23) which is firmly connected to the second part (4) is inserted into the Fig. 1c shown unlocked position of the locking device (1) rotated.
- Fig. 1d is the in 1a-c Locking device (1) described in detail is shown in a perspective view.
- a translation of a linear movement of a first part (3) of a multi-part housing core (5) into a rotary movement of an unlocking means is possible.

- the locking bolt (26) is held in the locking position by a spring (27) which rests with an upper end (28) against an underside (29) of the locking bolt (26).
- the locking bolt (26) also has a recess (30) into which an actuating bolt (31) protruding from a second, sleeve-like part (4a) of a housing core (5a) engages.
- the bolt (31) is integrally and eccentrically formed on an end of the cylindrical part (4a) facing the locking bolt (26) and can be rotated by an actuation angle when a driver pin (16a) moves from an initial position to an end position.
- the bolt (31) presses against an underside (32) of the recess and causes a linear movement of the locking bolt (26) against a force of the spring (27) into the Fig. 2c shown unlocking position.
- a first housing core part (3, 3a) of a multi-part housing core (5; 5a) can be moved from an end position of a driving pin (16; 16a) back to an initial position of the driving pin (16; 16a), a in Fig. 1 and 2nd not shown, in Fig. 3 and 4th with (53; 53a) designated restoring means can be provided, which is designed in particular as a helical or leaf spring and is inserted between the first housing core part (3; 3a) and a second housing core part (4; 4a) in the multi-part housing core (5; 5a) .

- the locking pin (34) engages behind with a circumferential projection (35) at one end (36) Fig. 3 Opening, not shown, in a wall of a safe door.
- An end (37) facing away from the first end has an annular groove (38) into which a locking projection (39) of a locking bolt (26b) engages in a locking position of the locking device when the locking pin (34) is inserted into the sleeve section (33) .
- the locking bolt (26b) comes out of the housing (2b) into the sleeve section (33).
- a suitable key is inserted into a one-piece housing core (5b) and linearly into the housing (2b) in an unlocked position of the locking elements (11b) moved in.
- An actuating element (40) tapering to a point in the actuating direction is eccentrically inserted into a recess (41) in the locking bolt (26b) and moves it against an elastic force of a spring (27b) into an unlocked position in which the locking projection (39) is no longer in the annular groove (38) engages.
- the locking device (1b) is provided for insertion into a door of the safe, while the locking pin (34) can be inserted into a wall of the safe.

Zweckmäßigerweise bewirkt eine lineare Bewegung des Entsperrmittels (7; 7a; 7c) eine Betätigung eines Entriegelungsmittels (23; 26; 26b; 42). Vorteilhaft ist zum Entriegeln der Verriegelungseinrichtung keine Drehbewegung eines passenden Entsperrmittels erforderlich.The invention relates to a locking device (1; 1a; 1b; 1c), in particular for locking a box provided with a flap, which has a housing (2; 2a; 2b; 2c) with a housing core (5; 5a; 5b; 5c) and comprises at least one locking element (11; 11a; 11b; 11c), which is released by an unlocking means (7; 7a; 7c) from a locking position in which the housing core (5; 5a; 5b; 5c) is immovable into an unlocking position which the housing core (5; 5a; 5b; 5c) is movable relative to the housing (2; 2a; 2b; 2c) can be brought. A linear movement of the unlocking means (7; 7a; 7c) expediently actuates an unlocking means (23; 26; 26b; 42). Advantageously, no rotational movement of a suitable unlocking means is required to unlock the locking device.
Description
Die Erfindung betrifft eine Verriegelungseinrichtung, insbesondere zum Verriegeln eines mit einer Klappe versehenen Kastens, die ein Gehäuse mit einem Gehäusekern und mindestens ein Sperrelement umfasst, das durch ein Entsperrmittel aus einer Sperrstellung, in der der Gehäusekern unbeweglich ist, in eine Entsperrstellung, in der der Gehäusekern relativ zu dem Gehäuse bewegbar ist, gebracht werden kann.The invention relates to a locking device, in particular for locking a box provided with a flap, which comprises a housing with a housing core and at least one locking element which is released by an unlocking means from a locking position in which the housing core is immobile into an unlocking position in which the Housing core is movable relative to the housing, can be brought.
Aus dem Stand der Technik sind beispielsweise Briefkastenschlösser bekannt, die einen Schließzylinder mit einem zylindrischen Schließzylinderkern aufweisen. Durch Einstecken eines passenden Schlüssels in einen Aufnahmekanal des Schließzylinderkerns werden federnd gelagerte, mehrteilige rahmenartige oder stiftförmige Sperrelemente in eine Entsperrstellung bewegt und der Schließzylinderkern kann durch eine Drehung des Schlüssels relativ zu dem Gehäuse gedreht werden. Durch diese Drehung wird ein mit dem Kern fest verbundener Sperrriegel in eine Entriegelungsstellung verschwenkt und die Klappe kann geöffnet werden. Je nach Ausbildung des Schließzylinders ist eine Drehung des Schlüssels um 90 bis 180 Grad erforderlich.Letter box locks are known from the prior art, for example, which have a locking cylinder with a cylindrical locking cylinder core. By inserting a suitable key into a receiving channel of the lock cylinder core, spring-mounted, multi-part frame-like or pin-shaped locking elements are moved into an unlocked position and the lock cylinder core can be rotated relative to the housing by rotating the key. This rotation causes a locking bolt that is firmly connected to the core to be pivoted into an unlocking position and the flap can be opened. Depending on the design of the lock cylinder, the key must be turned 90 to 180 degrees.
Aus dem Stand der Technik sind ferner drehbare Griffe zum Öffnen von Türen, Fenstern oder Klappen bekannt, die einen Schließzylinder mit einem zylindrischen Schließzylinderkern aufweisen. Der Schließzylinder dient zur Sperrung einer Drehbewegung des Griffes, wodurch eine unbefugte Öffnung der Tür, des Fensters oder der Klappe verhindert wird. Durch Einstecken eines passenden Schlüssels in einen Aufnahmekanal des Schließzylinderkerns werden federnd gelagerte, mehrteilige rahmenartige oder stiftförmige Sperrelemente in eine Entsperrstellung bewegt und der Schließzylinderkern kann durch eine Drehung des Schlüssels relativ zu dem drehbaren Griff verdreht werden. Durch diese Drehung wird ein mit dem Kern fest verbundener Sperrriegel in eine Entriegelungsstellung verschwenkt und der Griff kann gedreht werden. Die Tür, das Fenster oder die Klappe können geöffnet werden. Je nach Ausbildung des Schließzylinders ist eine Drehung des Schlüssels um 90 bis 180 Grad erforderlich.Rotatable handles for opening doors, windows or flaps are also known from the prior art, which have a locking cylinder with a cylindrical locking cylinder core. The locking cylinder is used to block a rotary movement of the handle, which prevents unauthorized opening of the door, window or flap. By inserting a suitable key into a receiving channel of the lock cylinder core, resiliently mounted, multi-part frame-like or pin-shaped locking elements are moved into an unlocked position and the lock cylinder core can be rotated relative to the rotatable handle by rotating the key. This rotation causes a locking bolt which is firmly connected to the core to be pivoted into an unlocking position and the handle can be rotated. The door, the window or the flap can be opened. Depending on the design of the lock cylinder, the key must be turned 90 to 180 degrees.
Der vorliegenden Erfindung liegt die Aufgabe zugrunde, eine Verriegelungseinrichtung der eingangs genannten Art zu schaffen, die ein sehr einfaches Entriegeln ermöglicht. Ferner liegt der Erfindung die Aufgabe zugrunde, eine Verriegelungseinrichtung zu schaffen, die vollständig im Innern eines mit einer Klappe zu verriegelnden Kastens angebracht werden kann.The present invention has for its object to provide a locking device of the type mentioned that enables a very simple unlocking. Furthermore, the invention has for its object to provide a locking device which can be attached completely inside a box to be locked with a flap.
Erfindungsgemäß wird die Aufgabe dadurch gelöst, dass eine lineare Bewegung des Entsperrmittels eine Betätigung eines Entriegelungsmittels bewirkt.According to the invention, the object is achieved in that a linear movement of the unlocking means causes an unlocking means to be actuated.
Vorteilhaft ist zum Entriegeln der Verriegelungseinrichtung keine Drehbewegung eines passenden Entsperrmittels erforderlich. Beispielsweise kann ein Schlüssel in einen Aufnahmekanal der erfindungsgemäßen Verriegelungseinrichtung eingesteckt werden, um die Sperrelemente in die Entsperrstellung zu bewegen. Durch eine weitere Linearbewegung des Schlüssels wird ein Entriegelungsmittel betätigt, wodurch die Verriegelungseinrichtung entriegelt wird. Eine Klappe eines Briefkastens oder eines anderen mit einer Klappe verschlossenen Behälters, beispielsweise eines Schranks oder eines Spinds, kann geöffnet werden oder eine Drehbewegung eines Griffes für eine Öffnung, insbesondere eines Fensters, kann freigegeben werden. Eine Drehbewegung des Entsperrmittels ist zum Entriegeln vorteilhaft nicht erforderlich.Advantageously, no rotational movement of a suitable unlocking means is required to unlock the locking device. For example, a key can be inserted into a receiving channel of the locking device according to the invention in order to move the locking elements into the unlocked position. A further linear movement of the key actuates an unlocking means, whereby the locking device is unlocked. A flap of a mailbox or another container closed with a flap, for example a cupboard or a locker, can be opened or a rotary movement of a handle for an opening, in particular a window, can be released. A rotational movement of the unlocking means is advantageously not required for unlocking.
Dadurch, dass zum Entriegeln keine Drehbewegung, sondern eine Linearbewegung erforderlich ist, kann die erfindungsgemäße Verriegelungseinrichtung vorteilhaft vollständig im Innern des Kastens oder eines drehbaren Fenstergriffes angebracht werden. Ein Hindurchführen eines Schließzylinders beispielsweise durch eine Klappe eines zu verriegelnden Kastens oder drehbaren Griffes ist nicht erforderlich, ein Schlitz in der Klappe oder dem drehbaren Griff zum Hindurchstecken eines Entsperrmittels ist ausreichend.Because a rotational movement, but a linear movement, is required for unlocking, the locking device according to the invention can advantageously be fitted completely inside the box or a rotatable window handle. It is not necessary to pass a locking cylinder, for example, through a flap of a box to be locked or a rotatable handle, a slot in the flap or the rotatable handle is sufficient for inserting an unlocking means.
Zweckmäßigerweise ist ein Betätigungselement linear bewegbar, drehbar oder verschwenkbar oder/und senkrecht, schräg, parallel oder koaxial zu einer Bewegungsrichtung des Entsperrmittels bewegbar. Die lineare Einschubbewegung des Entsperrmittels, die eine Einschubbewegung eines Schlüssels sein kann, wird in eine Linearbewegung, eine Drehbewegung oder eine Schwenkbewegung des Betätigungselements übersetzt. Vorteilhaft ist beispielsweise aus einem kurzen Einschubweg des Entsperrmittels ein langer Hub- oder Drehweg des Entriegelungsmittels aus einer Verriegelungsstellung in eine Entriegelungsstellung möglich. Das Betätigungselement kann außerdem dazu eingerichtet sein, eine stoff-, kraft- und/oder formschlüssige Verbindung mit dem Entriegelungsmittel, das einen Sperrriegel aufweisen kann, auszubilden.Advantageously, an actuating element can be moved linearly, rotated or pivoted and / or moved vertically, obliquely, parallel or coaxially to a direction of movement of the unlocking means. The linear insertion movement of the unlocking means, which can be an insertion movement of a key, is translated into a linear movement, a rotary movement or a pivoting movement of the actuating element. For example, a long stroke or rotation of the unlocking means from a locking position into an unlocking position is advantageously possible from a short insertion path of the unlocking means. The actuator can also be set up to form a material, non-positive and / or positive connection with the unlocking means, which may have a locking bolt.
In einer Ausgestaltung der Erfindung weist der Gehäusekern einen von einer Zylinderform abweichende Form auf und umfasst insbesondere eine rechteckige Grundfläche. Dadurch, dass keine Drehbewegung des Gehäusekerns zu Entriegelung erforderlich ist, wird eine Gestaltungsfreiheit vorteilhaft vergrößert. Weiter vorteilhaft kann ein Gehäusekern mit rechteckiger Grundfläche stabiler in einem Gehäuse geführt werden und ist gegen Verkippen gesichert.In one embodiment of the invention, the housing core has a shape deviating from a cylindrical shape and in particular comprises a rectangular base area. The fact that no rotational movement of the housing core is required for unlocking means that freedom of design is advantageously increased. A housing core with a rectangular base area can also be guided more stably in a housing and is secured against tilting.
Zweckmäßigerweise ist ein Betätigungselement an den Gehäusekern angebracht, vorzugsweise an eine dem Entriegelungsmittel zugewandte Stirnseite, und insbesondere einstückig angeformt. Denkbar ist auch, dass das Betätigungselement aus einem anderen Material gebildet ist und/oder andere mechanische Eigenschaften als der Gehäusekern aufweist. Vorteilhaft ist eine einfache Herstellung möglich.An actuating element is expediently attached to the housing core, preferably on an end face facing the unlocking means, and in particular is formed in one piece. It is also conceivable that the actuating element is formed from a different material and / or has different mechanical properties than the housing core. Simple manufacture is advantageously possible.
In einer Ausgestaltung der Erfindung weist das Entriegelungsmittel einen bewegbaren Sperrriegel auf, der vorzugsweise linear bewegbar oder verschwenkbar ist. Der Sperrriegel ist dazu eingerichtet ist, einen Verriegelungsvorsprung zu hintergreifen. Ist der Sperrriegel linear bewegbar, könnte er zum Hintergreifen des Verriegelunsgvorsprungs, der ein Rahmenabschnitt eines Briefkastengehäuses sein kann, ein- und ausgefahren werden. Vorteilhaft ist eine sehr kompakte Bauweise möglich. Ein Einfahrweg von 3 bis 10 mm kann bereits ausreichen, um eine besonders einbruchsichere Verriegelung zu bewirken. Der Sperrriegel kann außerdem aus einem flachen Metallstück gebildet sein, das in einer Verriegelungsstellung den Verriegelungsvorsprung hintergreift und in eine Entriegelungsstellung verschwenkt werden kann. Eine Bewegung des Sperrriegels senkrecht, parallel, koaxial oder schräg zur linearen Bewegungsrichtung des Entsperrmittels ist denkbar.In one embodiment of the invention, the unlocking means has a movable locking bolt, which is preferably linearly movable or pivotable. The locking bolt is set up to engage behind a locking projection. If the locking bar can be moved linearly, it could be extended and retracted to engage behind the locking projection, which can be a frame section of a letter box housing. A very compact design is advantageously possible. A drive-in path of 3 to 10 mm can be sufficient to achieve a particularly burglar-proof locking. The locking bolt can also be formed from a flat piece of metal which engages behind the locking projection in a locking position and can be pivoted into an unlocking position. A movement of the locking bolt perpendicular, parallel, coaxial or oblique to the linear direction of movement of the unlocking means is conceivable.
In einer weiteren Ausgestaltung der Erfindung ist der Gehäusekern mehrteilig ausgebildet, wobei ein erster Gehäusekernteil zur Aufnahme des Entsperrmittels, insbesondere eines Schlüssels, eingerichtet und insbesondere zylinderförmig ausgebildet ist. Ist der Gehäusekern mehrteilig ausgebildet, kann vorteilhaft eine Übersetzung der Linearbewegung des Entsperrmittels in eine andersartige Bewegung weiterer Gehäusekernteile erfolgen. Der mehrteilige Gehäusekern wirkt getriebeähnlich und setzt eine Linearbewegung beispielsweise in eine Drehbewegung weiterer Gehäusekernteile um.In a further embodiment of the invention, the housing core is formed in several parts, a first housing core part being designed to receive the unlocking means, in particular a key, and in particular being cylindrical. If the housing core is constructed in several parts, the linear movement of the unlocking means can advantageously be translated into a different type of movement of further housing core parts. The multi-part housing core acts like a gear and converts a linear movement, for example, into a rotary movement of further housing core parts.
In einer Ausgestaltung der Erfindung ist ein zweiter Gehäusekernteil hülsenanartig ausgebildet, umschließt den ersten Gehäusekernteil zumindest teilweise und ist um eine Längsachse drehbar. Vorteilhaft kann eine Linearbewegung des ersten Gehäusekernteils, der zur Aufnahme des Entsperrmittels vorgesehen sein kann, in eine Drehbewegung des zweiten Gehäusekernteils um eine Längsachse umgewandelt werden. Ist an den zweiten Gehäusekernteil ein Betätigungselement angebracht, kann durch dessen exzentrische Anbringung ein in Umfangsrichtung zurückzulegender Betätigungsweg oder -winkel festgelegt werden.In one embodiment of the invention, a second housing core part is designed like a sleeve, at least partially surrounds the first housing core part and can be rotated about a longitudinal axis. A linear movement of the first housing core part, which can be provided for receiving the unlocking means, can advantageously be converted into a rotary movement of the second housing core part about a longitudinal axis. If an actuating element is attached to the second housing core part, an actuation path or angle to be covered in the circumferential direction can be determined by its eccentric attachment.
Zweckmäßigerweise weist ein zweiter Gehäusekernteil eine Nut auf, in die ein von dem ersten Gehäusekernteil in Richtung des zweiten Gehäusekernteils vorstehendes Mitnehmerelement eingreift. Vorzugsweise sind beide Gehäusekernteile zylinderförmig ausgebildet und koaxial zueinander. Vorteilhaft kann durch das Mitnehmerelement, das insbesondere als Mitnehmerstift ausgebildet sein kann, eine Linearbewegung des ersten Gehäusekernteils in eine Drehbewegung des zweiten Gehäusekernteils umgewandelt werden. Ist beispielsweise eine Drehung eines Betätigungselements um einen Winkel von 90 Grad bei einem kurzen Einschubweg eines Schlüssels erforderlich, kann die Nut eine überwiegend in Umfangsrichtung verlaufenden Richtungskomponente aufweisen. Ist eine Drehung bei einem langen Einführweg eines Schlüssels erforderlich, kann die Nut eine überwiegend in einer Einschubrichtung verlaufende Richtungskomponente aufweisen. Vorzugsweise ist ein Weg, den das Mitnehmerelement in Längsrichtung zurücklegt genauso lang wie ein Weg in Umfangsrichtung.A second housing core part expediently has a groove into which a driver element protruding from the first housing core part in the direction of the second housing core part engages. Both housing core parts are preferably cylindrical and coaxial with one another. A linear movement of the first housing core part can advantageously be converted into a rotary movement of the second housing core part by the driver element, which can be designed in particular as a driver pin. If, for example, a rotation of an actuating element by an angle of 90 degrees is necessary with a short insertion path of a key, the groove can have a directional component that runs predominantly in the circumferential direction. If a rotation is necessary with a long insertion path of a key, the groove can have a directional component that runs predominantly in one insertion direction. A path that the driver element travels in the longitudinal direction is preferably as long as a path in the circumferential direction.
In einer Ausgestaltung der Erfindung ist ein erster Gehäusekernteil eines mehrteiligen Gehäusekerns in der Entsperrstellung linear bewegbar und ein zweiter Gehäusekernteil, der den ersten Gehäusekernteil hülsenartig umschließt, ist in der Entsperrstellung drehbar. Die lineare Bewegung kann durch einen passenden Schlüssel bewirkt werden, der in den ersten Gehäuseteil eingesteckt ist und in eine Einsteckrichtung weiter bewegt, insbesondere eingeschoben wird. Vorteilhaft kann eine Linearbewegung des ersten Gehäusekernteils in eine Drehbewegung des zweiten Gehäusekernteils übersetzt werden.In one embodiment of the invention, a first housing core part of a multi-part housing core can be moved linearly in the unlocked position and a second housing core part, which surrounds the first housing core part like a sleeve, can be rotated in the unlocked position. The linear movement can be brought about by a suitable key which is inserted into the first housing part and moves further in an insertion direction, in particular is inserted. A linear movement of the first housing core part can advantageously be translated into a rotary movement of the second housing core part.
In einer Ausgestaltung der Erfindung ist ein Rückstellmittel vorgesehen, das vorzugsweise eine Schraubenfeder aufweist und das zwischen einem Gehäuse und einem einteiligen Gehäusekern oder zwischen einem ersten Gehäusekernteil und einem zweiten Gehäusekernteil eines mehrteiligen Gehäusekerns angeordnet ist. Eine Linearbewegung des Gehäusekerns oder des ersten Teils des Gehäusekerns beim Entriegeln der Verriegelungseinrichtung erfolgt entgegen einer Rückstellkraft des Rückstellmittels. Dadurch ist vorteilhaft eine Zurückbewegung des Gehäusekerns oder des ersten Gehäusekernteils beim Entfernen des Entsperrmittels, beispielsweise beim Herausziehen eines Schlüssels, möglich.In one embodiment of the invention, a restoring means is provided which preferably has a helical spring and which is arranged between a housing and a one-piece housing core or between a first housing core part and a second housing core part of a multi-part housing core. A linear movement of the housing core or the first part of the housing core when unlocking the locking device takes place against a restoring force of the restoring means. This advantageously allows the housing core or the first housing core part to be moved back when the unlocking means is removed, for example when a key is removed.
Zweckmäßigerweise umfasst ein Entsperrmittel zur Verwendung mit der Verriegelungseinrichtung einen elektronischen Schlüssel, auf dem Daten gespeichert sind, die an eine Steuereinheit übermittelt werden, die zur Ansteuerung mindestens eines vorzugsweise elektrischen Antriebs eingerichtet ist, der zur Bewegung der Sperrelemente in eine Entsperrstellung und zur Linearbewegung eines Gehäusekerns oder einen ersten Gehäusekernteils eines mehrteiligen Gehäuses vorgesehen ist. Die Steuereinheit prüft, ob die Daten auf dem elektronischen Schlüssel, der einen RFID-Chip aufweisen kann, zur Entriegelung der Einrichtung berechtigen. Ist dies der Fall, werden die Sperrelemente in die Entsperrstellung bewegt und der Gehäusekern oder ein erster Gehäusekernteil eines mehrteiligen Gehäusekerns wird linear in ein Gehäuse hineinbewegt.Expediently, an unlocking means for use with the locking device comprises an electronic key, on which data are stored, which are transmitted to a control unit, which is set up to control at least one preferably electric drive, which is used to move the locking elements into an unlocked position and to linearly move a housing core or a first housing core part of a multi-part housing is provided. The control unit checks whether the data on the electronic key, which can have an RFID chip, authorize the device to be unlocked. If this is the case, the locking elements are moved into the unlocked position and the housing core or a first housing core part of a multi-part housing core is moved linearly into a housing.
In einer Ausgestaltung der Erfindung ist ein Entriegelungsmittel, das insbesondere einen vorzugsweise linear bewegbaren Sperrriegel oder ein mehrteiliges Verriegelungselement umfasst, innerhalb des Gehäuses oder innerhalb eines an das Gehäuse angeformten Aufnahmeabschnitts angeordnet. Das mehrteilige Verriegelungselement ist vorzugsweise zweiteilig ausgebildet und kann zum Hintergreifen eines Sperrstiftes eingerichtet sein. Dazu können zwei halbkreisförmige Ringabschnitte vorgesehen sein.
Der Aufnahmeabschnitt kann zur Aufnahme eines Sperrstiftes vorgesehen sein, der in den Aufnahmeabschnitt hineintaucht, und ferner als Hülsenabschnitt ausgebildet sein. Vorteilhaft ist das Entriegelungsmittel durch das Gehäuse oder den Aufnahmeabschnitt vor Verschmutzung geschützt.In one embodiment of the invention, an unlocking means, which comprises in particular a preferably linearly movable locking bolt or a multi-part locking element, is arranged inside the housing or within a receiving section molded onto the housing. The multi-part locking element is preferably formed in two parts and can be set up to engage behind a locking pin. For this purpose, two semicircular ring sections can be provided.
The receiving section can be provided for receiving a locking pin which dips into the receiving section and can also be designed as a sleeve section. The unlocking means is advantageously protected against contamination by the housing or the receiving section.
In einer weiteren Ausgestaltung der Erfindung ist ein Entriegelungsmittel vorgesehen, das sowohl in einer Entriegelungsstellung als auch in einer Verriegelungsstellung innerhalb des Gehäuses oder innerhalb eines an das Gehäuse angeformten Aufnahmeabschnitts angeordnet ist. Vorteilhaft ist eine besonders kompakte Ausbildung der Verriegelungseinrichtung möglich.In a further embodiment of the invention, an unlocking means is provided, which is arranged both in an unlocking position and in a locking position within the housing or within a receiving section molded onto the housing. A particularly compact design of the locking device is advantageously possible.
Zweckmäßigerweise sind zwei Rückstellmittel vorgesehen, von denen ein erstes zwischen einem Gehäuse und einem einteiligen Gehäusekern oder zwischen einem ersten Gehäusekernteil und einem zweiten Gehäusekernteil eines mehrteiligen Gehäusekerns angeordnet ist, und ein zweites zwischen dem Gehäuse und einem Entriegelungsmittel. Die Rückstellmittel können beispielsweise als Schraubenfedern ausgebildet sein.
Eine rein mechanische Betätigung der Verriegelungseinrichtung ist möglich. Zum bestimmungsgemäßen Gebrauch Strom erfordernde, batteriebetriebene elektrische oder elektronische Komponenten sind nicht erforderlich. Vorteilhaft ist die Verriegelungseinrichtung besonders ausfallsicher.Two reset means are expediently provided, of which a first between a housing and a one-part housing core or between a first housing core part and a second housing core part of a multi-part housing core is arranged, and a second between the housing and an unlocking means. The restoring means can be designed, for example, as coil springs.
A purely mechanical actuation of the locking device is possible. Battery-operated electrical or electronic components that require current are not required. The locking device is advantageously particularly fail-safe.
In einer Ausgestaltung der Erfindung greift das Entriegelungsmittel in einer Verriegelungsstellung in eine Ringnut eines Sperrmittels ein oder hintergreift einen Haltevorsprung eines Sperrmittels. Das Sperrmittel ist vorzugsweise als Sperrstift ausgebildet, der fest mit einer Behälterinnenwand oder einer Klappe des Behälters verbunden ist.In one embodiment of the invention, the unlocking means engages in an locking position in an annular groove of a locking means or engages behind a retaining projection of a locking means. The locking means is preferably designed as a locking pin which is fixedly connected to a container inner wall or a flap of the container.
Zweckmäßigerweise ist das mindestens eine Sperrelement stiftförmig, stabförmig oder rahmenartig ausgebildet und vorzugsweise durch ein Rückstellmittel, insbesondere eine Feder, in der Sperrstellung gehalten. Besonders vorteilhaft ist eine rahmenartige Ausbildung, da die Herstellung rahmenartiger Sperrelemente besonders einfach ist. Außerdem sind solche Sperrelemente bei einer Montage leichter handzuhaben.The at least one locking element is expediently pin-shaped, rod-shaped or frame-like and is preferably held in the locking position by a restoring means, in particular a spring. A frame-like design is particularly advantageous since the production of frame-like locking elements is particularly simple. In addition, such locking elements are easier to handle during assembly.
In einer Ausgestaltung der Erfindung weist das Gehäuse ein Sichtfenster auf, durch das eine Stellung eines Verbindungsmittels, das einen ersten Gehäusekernteil mit einem zweiten Gehäusekernteil eines mehrteiligen Gehäuses verbindet, erkennbar ist. Vorteilhaft kann ein Benutzer der Verriegelungseinrichtung anhand einer Stellung des Verbindungsmittels erkennen, ob die Einrichtung ver- oder entriegelt ist. Beispielsweise kann das Verbindungsmittel ein Mitnehmerstift sein, der mit einem ersten Endabschnitt in eine Öffnung in dem ersten Gehäusekernteil eingesteckt ist und mit einem zweiten Endabschnitt in eine Nut in dem zweiten Gehäusekernteil eingreift.In one embodiment of the invention, the housing has a viewing window through which a position of a connecting means that connects a first housing core part to a second housing core part of a multi-part housing can be recognized. A user of the locking device can advantageously recognize from the position of the connecting means whether the device is locked or unlocked. For example, the connecting means can be a driver pin, which is inserted with a first end section into an opening in the first housing core part and engages with a second end section into a groove in the second housing core part.

Die Sperrelemente (11) sind in dem ersten Teil (3) auf Schraubenfedern (12) gelagert, wobei jede der Schraubenfedern (12) mit einer Unterseite (13) gegen einen in
Zum Entsperren, das heißt zur Bewegung der Sperrelemente (11) aus einer Sperrstellung in eine Entsperrstellung, wird ein passender Schlüssel (7) in den Kanal des ersten Teils (3) eingeführt. Dadurch werden die Sperrabschnitte (10) der Sperrelemente (11) entgegen einer Federkraft der Schraubenfedern (12) durch die Öffnungen (9) hindurch in das Innere des ersten Gehäusekernteils (3) bewegt. In der Entsperrstellung kann der erste Gehäusekernteil (3) linear gegenüber dem zweiten Gehäusekernteil (4) in Richtung einer Schlüsseleinführrichtung in diesen hineinbewegt werden.A suitable key (7) is inserted into the channel of the first part (3) for unlocking, ie for moving the locking elements (11) from a locking position into an unlocking position. As a result, the locking sections (10) of the locking elements (11) are moved against the spring force of the coil springs (12) through the openings (9) into the interior of the first housing core part (3). In the unlocked position, the first housing core part (3) can be moved linearly relative to the second housing core part (4) in the direction of a key insertion direction.
Von dem ersten Gehäusekernteil (3) steht ferner ein vorzugsweise aus einem Metall gebildeter Mitnehmerstift (16) vor, der mit einem Stiftkopf (17) in eine sich in Längs- und Umfangsrichtung erstreckende Nut (18) im zweiten Teil (4) eingreift. Die Nut (18) ist in radialer Richtung der zylinderförmigen Hülse durchgehend.From the first housing core part (3) there is also a driver pin (16), which is preferably formed from a metal and which, with a pin head (17), extends longitudinally and Groove (18) which extends in the circumferential direction engages in the second part (4). The groove (18) is continuous in the radial direction of the cylindrical sleeve.
Wird der erste Gehäusekernteil (3) in einer Entsperrstellung der Sperrelemente (11) durch Druck auf den Schlüssel in dessen Achsrichtung linear in den zweiten Gehäusekernteil (4) hinein bewegt, bewirkt diese Linearbewegung eine gradlinige Bewegung des Mitnehmerstiftes (16) aus einer Anfangsstellung, in der er gegen ein erstes Nutende (19) anliegt, in eine Endstellung, in der der Mitnehmerstift (16) gegen ein zweites Nutende (20) anliegt. Bei der geradlinigen Bewegung aus der Anfangsstellung in die Endstellung wird der zweite Teil (4) gegenüber dem ersten Teil (3) um einen Betätigungswinkel gedreht. Dieser beträgt in diesem Ausführungsbeispiel 90 Grad, da das erste (19) und das zweite Nutende (20) in Umfangsrichtung des zylindrischen zweiten Teils (4) um einen Winkel von 90 Grad zueinander versetzt angeordnet sind. Ferner ist ein Einschubweg, um den der erste Teil (3) in den zweiten Teil (4) hineingeschoben wird, genauso groß wie ein Weg in Umfangsrichtung, um den der zweite Teil gedreht wird. Dadurch wird eine besonders gute Übersetzung einer Linearbewegung in eine Drehbewegung erreicht.If the first housing core part (3) is moved linearly into the second housing core part (4) in the unlocked position of the locking elements (11) by pressing the key in its axial direction, this linear movement causes a straight movement of the driver pin (16) from an initial position in which it bears against a first groove end (19), in an end position in which the driver pin (16) bears against a second groove end (20). When moving straight from the starting position to the end position, the second part (4) is rotated by an actuation angle with respect to the first part (3). In this exemplary embodiment, this is 90 degrees, since the first (19) and the second groove end (20) are offset from one another by an angle of 90 degrees in the circumferential direction of the cylindrical second part (4). Furthermore, an insertion path by which the first part (3) is pushed into the second part (4) is the same size as a path in the circumferential direction by which the second part is rotated. A particularly good translation of a linear movement into a rotary movement is thereby achieved.
Dadurch, dass der zweite Gehäusekernteil (4) auf einer Außenseite mit einem Betätigungselement (21) versehen ist, das aus dem Gehäuse (2) hinausragt und an das ein als Sperrriegel ausgebildetes Entriegelungsmittel (23) durch eine Befestigungsklemme (22) angebracht ist, wird der Riegel (23) bei der Drehung des zweiten Gehäusekernteils (4) um den Betätigungswinkel von 90 Grad aus einer Grundstellung heraus in eine Entriegelungsstellung gedreht. Es versteht sich, dass andere Betätigungswinkel denkbar sind, beispielsweise zwischen 30 und 90 Grad, insbesondere 30, 45 und 60 Grad.Characterized in that the second housing core part (4) is provided on the outside with an actuating element (21) which protrudes from the housing (2) and to which an unlocking means (23) in the form of a locking bolt is attached by a fastening clamp (22) the bolt (23) is rotated by the actuation angle of 90 degrees from a basic position into an unlocking position when the second housing core part (4) is rotated. It goes without saying that other actuation angles are conceivable, for example between 30 and 90 degrees, in particular 30, 45 and 60 degrees.

An actuating element (40) tapering to a point in the actuating direction is eccentrically inserted into a recess (41) in the locking bolt (26b) and moves it against an elastic force of a spring (27b) into an unlocked position in which the locking projection (39) is no longer in the annular groove (38) engages.
