Description

The invention relates to rotary locks according to the preamble of claim 1.

To objects between a substantially freely accessible area and a Room with a high security requirement, especially a bank, move too can, locks are used, which restricts to desired displacements enable.

From US 4 299 175 a rotary lock is known in which a rotary body in a Housing is rotatably mounted about a vertical axis of rotation. The rotary body comprises between a bottom and an upper end ring one in the sectional view part-annular wall, wherein the interior of the rotary body by the area opening formed without wall is accessible. A portion of the wall is from a made of bullet-proof glass. This rotary lock is, for example, in a post office used and allows the operator on the safe side of the Lock, to see what from the publicly accessible side in the rotary lock is placed. If the object in the lock is unsuspected, the operator turns the lock with an arranged on the safe side actuator so far that the opening is accessible from the safe side. This rotary lock can only be used in the presence of an operator.

From DE 39 42 884 a rotary lock with horizontal axis is known in the in the rotary body, a fixed trough is arranged. The operation of the lock via a lever on the safe side. So that the person on the safe talking to the person on the public side is an intercom intended. This rotary lock can only in the presence of a Operator are used.

US 3 880 320 describes an apparatus for dispensing money with a a horizontal axis rotatable rotary body. The rotary body takes in one in Pick up money, turn to the outside, then inwards until an emptying position and then back to the receiving position. This money dispenser can not be used as a device for passing objects become.

For cash-in-transit companies, it is an undesirable restriction when they deliver money and taking money only during the opening hours of banks or other customers. You want transport containers at any time deliver and pick up cash. The from the state of the Technology known locks are used only in the operated state. solutions in the sense of a night safe are not suitable for inserting money suitcases. In addition, it would not be possible to pick something up from the bank or from the night safe refer to.

FR 2 729 431 describes a rotary lock with a vertical axis of rotation. One too transferring cassette is in the rotary lock to one with a central computer connected plug connected and the rotary body enters motor in a storage position. If the outer door to the rotary body is not closed or reopened, there is a risk that the cassette is under Application of violence can be taken.

The invention is based on the object to find a lock that between a substantially freely accessible area and a room with a high Safety requirements in both directions makes objects movable, even if only in the freely accessible area a user is present. The lock should be easy be constructed. and ensure a restriction to desired shifts. In addition to using the lock a simple and safe procedure to move objects.

This object is solved by the features of claim 1 and 10, respectively. The dependent ones Claims describe alternative or preferred embodiments.

An inventive lock comprises a housing and a rotatable in the housing mounted rotary body. On the housing is on a first page a first and on a second side of a second housing opening formed. The rotary body comprises a bottom and an upper end surface and a connecting the end surfaces Wall, wherein in a peripheral region of the rotary body, a lock opening is formed to an interior of the rotary body. In a first rotational position of the rotary body, the lock opening is at least partially aligned with the first housing opening and in a second rotational position with the second housing opening.

In a first inventive step it was recognized that a lock, of both Pages regardless of the presence of an authorized person on the other Page is to be used for a transfer of an object, together with the first and the second rotational position at least one closed rotational position of the rotary body must include. In the locked rotational position is the lock opening completely covered by a wall area of the housing. A thing can now be placed by a first person from a first page in the rotary body and the rotary body are rotated in the locked rotational position. Of the Rotary body is in the closed rotational position of a locking device locked so that the object can not be removed.

In a second inventive step, it was recognized that the transfer process without loss of control from the second person on a second side of the lock can be completed later when a direction of rotation control device the further rotation of the closed rotational position on one, if necessary adjustable, direction of rotation restricts. After unlocking the rotating body in the closed position is ensured by the direction of rotation control device, that the lock opening can only be turned towards the second side. A rotation back to the first page can be prevented. This can be guaranteed will be that every transfer process started will be completed must, before a new transfer process with the locked rotational position as safe waiting position is performed.

For solutions with only one closed rotational position, the direction of rotation control device the permitted direction of rotation for further rotation can change the locked rotational position. When the rotary body of the first side has reached the locked rotational position, so the further rotation must be restricted to the second side. If he is from the second page He has come into the locked position, so he may from the locked position can only be turned against the first page. This is for example with a Rätschenvorrichtung possible, each of which the free direction of rotation when reaching the first or second rotational position changes. This is about at least one Rätschenelement and at least one latching device provided, one of which Part is formed on the rotating body and a part of the housing. If turning when the closed rotational position to the first and second rotational position not only the Reverse rotation beyond the closed rotational position should also be prevented Snap-in possibilities can be provided throughout the turning range. For the Switching the direction of rotation is in the range of the first and second rotational position a Rätumumschaltungs device arranged. It would also be possible at least to provide two Rätschenelemente that engage in different directions. The direction of rotation would be changed by deflecting each one Rätschenelementes or possibly a latching achieved. When snapping Both Rätschenelemente a locking would be achieved, so that this arrangement can also be used as a locking device.

When two locked rotary positions are arranged so that when turning of the rotating body in one direction the first, one locked, the second, one closed and again the first rotational position is reached, so can on a Direction of rotation change can be omitted. The direction of rotation control device can be limited to a device which the direction of rotation at all Rotary positions permanently restricted to the same direction of rotation. To do this in Rätschenvorrichtungen example, at least one Rätschenelement and at least provided four snap-in devices. It goes without saying that various freewheel devices, such as those known from bicycle drive hubs are, or pinch roller freewheels are used. Such freewheel devices prevent turning back in any rotational position.

The locking device makes the rotating body at least in the closed Rotary positions, but optionally lockable in all four rotational positions. To release a rotational movement, the locking device, for example pull out a locking bolt from a recess.

An unlocking should only by authorized persons and only within a permissible Operation can be achieved. For solutions with two sealed Rotational positions is one of these closed rotational positions the preparation situation for the first rotational position and the other the preparation position for the second rotational position. If now the first rotational position of the substantially freely accessible first housing opening, or from the outside, ago accessible, so may from the outside only their assigned closed rotational position can be unlocked. If the rotating body is not prepared for external use or if it is is not in the correct locked rotational position, so can from the outside with the Turning nothing to be done. When the rotary body on the correct rotational position is, so can an authorized person with a key, a code or another unlocking of the revolving body achieve another authorization control. The unlocked rotary body can then be brought into the first rotational position in which the interior of the rotating body through the first housing opening, or from the outside, is accessible. Optionally, the rotary body is also in the first rotational position locked, then for further rotation a simple Unlocking must be possible. After a removal of an object or after inserting an object, the rotary body is closed in the next Rotary position brought and locked, which the preparation situation for an access to the interior of the rotary body through the second housing opening, or from inside, forms. Also in the second housing opening or inside can a Authorization checks are required to unlock the rotating body and to allow the rotation of the rotating body. It goes without saying that the Operation from inside more possibilities than outside. If, for example The use of the outside is not done, so can from about the inside Preparatory position for the use to be unlocked from the outside to the rotating body about the first rotational position and the next closed rotational position again to move to the second rotational position.

The rotating body is rotated manually, for example. He has to do that from both sides be so accessible in the area of the first and second housing opening so that he can be turned by hand. To facilitate the turning are on Rotary body about handle options provided. It goes without saying that Also embodiments are possible in which the rotation by a drive is achieved.

The rotary lock can in a simply constructed embodiment, in the example only the two locked rotary positions are locked, without Control operated. The unlocking of the two closed rotary positions then takes about with keys, the locking bolt preferably is biased against the locking position so that it reaches a closed rotational position without active actuation reaches the locking position. From the outside, only an unlocking of the assigned preparation position allows. The lock is simple and ensures a restriction on desired shifts.

With increased need for control, a control is used, which the locking device controls, with at least one authorization control device and, if necessary, a log of the movements carried out and in particular user leads. The rotational positions become, for example made detectable by positioner by the controller. To capture, that the rotating body has been set in motion starting from a rotational position, the signals of the position sensors can be used. If necessary, becomes Rotational motion detection but with a Rätschensensor a deflection of the Rätschenelementes detected. For example, after a detected initial movement a locking bolt are brought into position or bias, that when reaching a next rotational position in a corresponding Recess engages and prevents any further rotation. The control preferably also includes at least one timer. For example for the filling or emptying process from the freely accessible side, a time window within which the process should be completed. If the rotary body does not return within a predetermined time within the given time Turning position is, so a warning signal is issued. An extremely short time interval is approximately provided between the detection of the start of shooting and the Preloading the locking bolt. When using a rotary drive is the controller also connected to the rotary drive.

The controller can also be connected to a warning or alarm system. Around to ensure the operation of the alarm system independently of the control is but preferably separated from the controller and includes at least one, but especially two, own position transmitter. The position sensors of the alarm system are arranged and included in the circuit of the alarm system that the Alarm system is turned on when the rotary body in the closed rotational positions is. In all other positions, that is during filling or emptying the alarm is switched off to prevent false alarms. To trigger a Alarmes example, the signal of a vibration sensor is used.

The wall areas of the rotating body and the housing are solid - for example, with two metal sheets and in between a concrete filling - so that An armor is achieved, as is common in safes. The armor and the fact that the rotating body is not pushed out of the housing can ensure a high level of security.

Fig. 1 shows a rotary lock 1 with a housing 2, the two wall portions 3 and a first and a second housing opening 2a, 2b comprises. In the housing 2 is a rotary body 4 rotatably arranged between a lower and an upper End surface 5a, 5b (see Fig. 5) one consisting of three sections Wall 6 has. The wall 6 forms a first peripheral region of the rotary body 4. In a second peripheral region makes a lock opening 7 an interior 8 of the rotary body 4 accessible. The rotary body 4 is via two pivot bearings. 9 mounted on the housing 2, wherein a rotation axis 9 centrally through the rotary body leads. The wall 6 extends over an angular range of at least 120 °, in particular but at least 270 °. In the remaining angular range is the lock opening 7 trained. In the illustrated embodiment, the interior 8 limited by a rectangular in section inside boundary 6a of the wall 6, wherein its size is chosen so that at least one common money transport case can be included. An outer boundary 6b of the wall 6 is connected to a Circular cylinder approximated, built up of several flat partial surfaces. The interior and Außenbundung 6a, 6b, for example, each formed by a metal sheet. Between the inner and outer boundary is a cured filler 6c, for example Cement or concrete filled. To the rotating body 4 manually in rotation to be able to put, are gripping devices 6d, in particular in the form of Recesses, or inwardly leading u-profiles provided.

The completely assembled housing 2 encloses the rotary body 4 so far, that he can not be removed from the housing 2. For this purpose, the both wall portions 3 at the first housing opening 2a projecting against each other first corner areas 3a. To insert the rotary body 4 are against each other protruding second corner portions 3b at the second housing opening 2b by means Screw 3c attached to the corresponding wall portions 3. in the illustrated embodiment, the first housing opening 2a is a lock cylinder 11 for receiving a key and the second housing opening 2b a Keypad 12 assigned to enter a code. The lock cylinder 11 and the Keypad 12 are via connection channels 11a and 12a (Fig. 5) with a receiving area 13 connected to a controller 16. It goes without saying that instead of the lock cylinder 11 and the keypad 12 also other authorization monitoring, for example, inductive or biometric systems, can be provided.

To the rotary body 4 in at least one, but preferably in at least two, To be able to lock the rotational position on the housing 2 is a locking device 14 provided (Fig. 6). To ensure a lock even when de-energized is, for example, a biasing spring 14a, or a permanent magnet provided, the or a locking bolt 14 b in a locking hole 14c presses. The locking bolt 14b is on the housing 2 in a Passed intermediate bottom 15 and the biasing spring 14 is under the locking bolt 14b fastened to the intermediate bottom 15 via a holder 14d. To the lock To be able to solve, an electromagnet 14e is arranged and dimensioned, that the superposition of the biasing force with the force of the electric magnetic field resulting in a resultant force, the locking bolt 14 b from the locking hole 14c retracts. The supply of the electromagnet 14e via a controller 16. In the illustrated embodiment are according to 1 four locking holes 14c arranged uniformly on a circular line, so that the rotary body 4 in four rotational positions of the locking bolt 14b can be locked on the housing 2.

In order to be able to detect the respectively current rotational position, there is a position detection device provided, which, for example, on the housing 2 four contact sensors 17a, in particular magnetic sensors, and on the rotary body 4, a position element 17b, in particular a permanent magnet, comprises (see Fig. 9). The contact sensors are arranged at angular intervals of 90 ° and can each be the presence of the item item. Optionally, another not shown Position detection device provided with two contact sensors, which an alarm system in the closed rotational positions turns on.

In a second rotational position of the rotary body 4 according to FIG. 1 is the Lock opening 7 in the region of the second housing opening 2b, which, for example facing the interior of a bank. A bank official can now get an item into the interior 8. If the rotary body 4 is locked, optionally the keypad 12 an unlocking signal deposited, the locking bolt 14b and preferably short, for example 1 second, pretension again after shooting. The rotary body 4 is rotated 90 ° counterclockwise turned. After this rotation, the rotary body 4 reaches the in Fig. 2nd shown closed rotational position, in which the rotary body 4 on the housing. 2 is locked. Now, the rotary body 4 in the preparatory or parking position for a process from the freely accessible side, the process for example is triggered by turning a key in the lock cylinder 11. By turning the key, the locking bolt 14b at least during a predetermined time interval, but in particular until the rotary body. 4 manually rotated, retracted. Upon reaching the illustrated in Fig. 3 first rotational position of the locking pin 14b enters a locking hole 14c. The article in the interior 8 can through the lock opening 7 and the first housing opening 2a are removed or replaced. In another process, only one object is placed in the empty interior 8 laid. To prevent the process from the accessible side not is completed, a warning signal can be emitted when the rotating body 4 remains more than a predetermined maximum time in the first rotational position. After Operation of a switch, not shown, or the lock cylinder 11 takes place a release so that the rotary body 4 can be further rotated until he in the next locked rotational position shown in FIG. 4 is locked again. A Operator on the safe side can now, for example, after entering a code on the keypad 12 release the lock and the rotary body 4 in the continue to turn the second rotational position according to FIG. 1 and remove an object or insert or replace.

The controller 16 in the receiving area 13 is via a maintenance door 18 with security lock 19 accessible only for service. The security lock 19 prevents the access of unauthorized persons to the controller 16.

Fig. 7 and 8 show a simple direction of rotation control device, which the Rotational possibility in all four mentioned rotational positions permanently in one direction of rotation limits. For this purpose, for example, at least one Rätschenelement 20th and at least four latching devices 21 formed on the intermediate bottom 15 intended. The Rätschenelement 20 is pivotally mounted on the lower end surface 5a of the rotary body 4 is fixed and lies with its free end on the surface of the false bottom 15. Preferably, four latching devices 21 so distributed on a circular line that in the four mentioned rotational positions a catch he follows.

According to FIGS. 10-13, the rotary lock 1 can simply be connected to a wall opening 22. or to be installed. In order to prevent a removal of the rotary lock 1 is they firmly connected to the masonry 22a and / or a frame 23, which is the rotary lock 1 carries, is firmly anchored to the ground. If on the freely accessible Side is a lockable cover door 24 is arranged so the rotary lock is the first not recognizable as a rotary lock 1 and is therefore no special attention awaken. The wall portions of the rotary body 4 and the housing 2 are solidly formed - for example, with two metal sheets and one in between Concrete filling - so that armor is achieved, as in armored cabinets is common. The armor and the fact that the rotary body 4 is not from the Housing 2 can be pushed, ensure a high level of security.
