However, the lock solution with other magnetic locks according to the invention is also applicable to the bolt-operated adjusting elements.

SUMMARY OF THE INVENTION It is an object of the present invention to provide locks of the above type with an additional locking device which is preferably remotely electrically operable and, in a preferred embodiment, allows the position and condition of the lock to be checked.

The principle is that

It is an object of the solution according to the invention that the additional locking device of the bolt is a closing yoke, the locking movement of which is controlled by the drive member. The lock has a sliding bolt operable by a customer key and optionally a bank key, and an additional locking device for locking or unlocking the bolt, the additional locking device being removable from the locking position by the bank key. Further, optionally, the key of the bank comprises a controllable ejection device for unlocking an additional locking device which is provided with leading surfaces corresponding to the leading surfaces of the respective bank key, which, when fully inserted into the key hole, allow relative movement of the ejection device relative to the bolt. The additional locking device is formed by a closing yoke, a controllable actuator, and the closing yoke is retractable and retractable from and into the barrier travel path. The additional locking device may be located in the bolt lock body or at the end portion of the bolt body, on the inside of the door. The actuator is preferably an electromagnet and the closing bracket is pivotable. There is a switch in the lock which, after switching on the solenoid and pivoting the closing caliper, keeps the closed current circuit of the solenoid, and another switch controlled by a bolt to break the solenoid current circuit when the bolt is moved from the locked position to the open position. In a preferred alternative of the lock, the switches are flexible or reed contacts, operable by permanent magnets provided on the bolt and closing bracket. The bolt is provided at the end, which is housed in the cavity of the lock body, with a stop for abutting the closing bracket in its closed position. The ejection device has an arm reaching to the stop surface and movable beyond this stop, which is provided at the end with a leading surface for lifting the closing yoke. The lock may be provided with further reed contacts to indicate the position of the bolt and the closing yoke.

Advantageously, a spring-loaded pivoting pawl is provided in the pushed position extending into the latch recess in the lock body, and an electrically operated retention device is provided in the lock body to keep the pivoting pawl in the open position when the bolt is moved. Preferably, the pivoting latch retention device is an electromagnetic module whose core arm abuts the pivoting latch to the side of its hinge with respect to the direction of travel of the bolt, the core arm retaining the pivoting latch by magnetic force, thereby pivoting the pivoting latch about another pivot point. Further, a sliding member which is connectable to the bolt by means of a locking body is arranged in the lock body. The blocking body is mounted in the sliding member in a transverse direction and a recess is formed in the lock body in which the blocking body is displaceable within a range corresponding to the length of the travel of the bolt travel. There is a recess in the bolt in which the locking body is partially mounted while the bolt is in the open position and the sliding member is in the extended position. Furthermore, it is advantageous if the electromagnetic module has at least two core arms, one of which is adjacent to or arranged near the rear end of the slider, the slide in its rearwardly retracted position overlapping the two core arms and bridging them magnetically. In the extended position it overlaps only one arm, thereby breaking the magnetic bridge between the two arms of the core.

Very advantageously, the sliding lock structure or the electronic evaluation and control device can be connected to the electrical housing.

BRIEF DESCRIPTION OF THE DRAWINGS FIG

1 is a schematic cross-sectional view, and FIGS. 2 and 5 show various functional positions. Fig. 3 according to line III-III and Fig. 4 IV-IV is a partial extension variant of a partial section according to the device in section of the side sliding lock in section according to section VIII of the view.

1 in FIG. FIG. 7 is a more perspective view. Fig. 8 is a view of Fig. 7. 9 and 10 show parts of the lock showing partial construction details. 11 and 12 in various functional positions.

Examples of embodiments of the invention

Fig. 1 shows an embodiment of a lock according to the invention in the closed position. In the body 1 there is a latch 2 which is movable to the right or to the left along the track 3. In the latch 2, two key holes 4 and 5 are provided, in which two keys are inserted, namely the customer key 6 and the bank key 7. These keys are provided in a known manner with magnets 8 and 9, against which the corresponding permanent magnets are arranged in the bolt 2 as rotatable adjusting elements 10.

In the latch 2, two recesses 11 are provided in which the sliding plates 12 are received. In the recesses 11, two parallel arms of the U-shaped part 13 of the ejection device 14, which is formed in one piece, are further mounted. Sliding plates 1.2 and section 13. The U-shaped elements are pressed into their end positions in the recesses 11 by springs 15. The ejection device 14 is shown in FIG.

The sliding plates 1.2 and the two arms of the U-shaped portion 1.3 are provided with pins 17, 26 extending into the inside of the recess 16 of the bolt 2. These pins 1.7, 26, when the sliding plate 12 or the sliding device 1.4 are moved against the spring 15 regions of the rotary adjusting elements 10 with permanent magnets, and depending on the rotational position of the rotating adjusting elements 1.0, pins 17,26 impact either the outer circumferential surface of the rotary adjusters 10 to limit further displacement, or the pins 17, 26 are inserted into the recess 18, 2.7 of the rotatable adjusting elements 10, thereby enabling a corresponding displacement. The position of rotation required for this is determined by the corresponding coding of the magnets 8, 9 of the corresponding keys. In addition, pins 21 are displaceably disposed in the sliding plates 12, extending on one side into the recess 22 in the body 1 or /

on the other side into the recess.

At the rear inner end of the lock, the bolt 2 is provided with a stop 5.0 which strikes the closing yoke 51 when the closing yoke 5.1 is in the closed position of FIG. 1. The clamping bracket 51 is pivotally mounted about an axis 52 and is provided with an armature 53. In this part of the lock, an electromagnet 54 is provided, to which current can be supplied by connections 55, 5, 6. By pulling the armature 53, the closing yoke 51 is swung upwards in the direction of the arrow 5.7, thereby releasing the bolt 2 and can be moved to the right. This position is shown in FIG.

In this upward deflected position of the closing yoke 5.1, the spring contact 5.8 closes. and the electromagnet 54 remains energized as long as the power supply is not interrupted. To activate the solenoid 54, a short-term current supply through the connections 55, 56 is sufficient, for example by a short pulse of a switch button controlled by a bank official, by which the closing yoke 51 is moved for an extended period of time to the open position.

By interrupting the current circuit of the solenoid 54, the closing yoke 51 drops down again and opens the resilient contact 58. If, when the current circuit is interrupted, the latch 2 is in the retracted position as shown in FIG. so that by means of the inserted keys 6, 7 it is possible to move the bolt 2 to the closed position and the closing bracket 51 again drops down to the closed position.

The current circuit of the electromagnet 54 is interrupted by a reed contact 60 controlled by a permanent magnet 6.1 of the bolt 2. In the position shown in Fig. 1, the current circuit is closed, the interrupted

If the bolt is moved, the magnet 61 moves away from the reed connection to the right, thereby disengaging the reed contact 68, the switches and thereby breaking the solenoid current circuit 54. The closing yoke 51 drops down onto the back portion 59 of the bolt 2 without restricting it. moving. This situation is also evident from FIG.

Another reed contact 6.3 is controlled by a permanent magnet 1.65. Its purpose is to signal, for example, on a panel controlled by a bank official, that the closing bracket 5.1 is in the open position according to FIG. 2 or in the closed position according to FIG. Also, another reed contact 62 operated by the permanent magnet 61 serves to inform the bank official to indicate the closed or open position of the bolt 2.

The information provided by the reed contact 6.3 is particularly important if the customer has moved the bolt 2 to the left without the shut-off bracket 5.1 having dropped to the closed position due to a failure, for example when the armature 53 of the electromagnet 54 is stuck.

In order to open the lock according to the invention, it is therefore necessary for the clerk to first engage the solenoid 5.4 at the compartment in order to raise the closure bracket 51. Then the customer has to insert his correct key 6 into the corresponding key opening 4 and relative movement between the sliding plate 1.2. and by a bolt 2 against the force of the spring 15. By this relative displacement it is achieved that the pin 21 can bend downwards into the recess 2.3 and the bolt 2 can be moved further to the right to the open position. The reed contact 6.0 interrupts the current circuit of the solenoid 54 so that the closing caliper 51 abuts the back portion 59 of the bolt 2. Reed contacts 62 and 6.3 signal to the official at the bulkhead that the bolt 2 is open and that the closing caliper 51 is swung up.

If the customer wishes to close the security compartment again, he must only use the key 6 to move the bolt 2 to the left. In the end position of FIG. 1, the closure bracket 51 drops to its closed position, thereby blocking the unauthorized movement of the bolt 2 to the right. Reed contacts 6.2. and 63 indicate to the official at the compartment that the bolt 2 is again in the closed position and that the closing bracket 5.1 is folded down and thus also in the closed position. The resilient contact 58 has opened, causing an interruption of the solenoid current circuit 5.4. On the other hand, a reed contact 60 closed by a permanent magnet 6.1 is arranged in the same current circuit, so that the lock is ready for re-opening.

The lock according to the invention can also be opened and closed even if, for example, the electromagnet 54 cannot be activated due to a power failure. In such a case, the key 7 of the flask must be inserted into the key hole.

This process is shown schematically in FIGS. 3 and 4 in the sectional area along lines III-III and IV-IV in FIG. In Fig. 4, the bank key 7 is in the partially retracted position. The ejection device 14 is in this position under the pressure of the spring 15, as can be seen from FIG. 1, so that the leading surface 6.5. it extends into the key opening 5. The lead key 7 also has a leading surface 66.

Push the key 7 in the direction arrows 6.7 with a pull-out device 14 moves in the direction of the arrow .6.8, NACC  with key 7 completely pushed to the key hole 5, as in another cuts shown on [0035] FIG. 3. by Fig.5 occurs on the inner end barriers 2 due to the internal ejection end of slide devices

14, to lift the closure bracket 51 by the action of the leading surface 69. After the closure bracket 51 is completely raised, the bolt 2 can be moved to the right, as described above, and the lock can be opened. FIG. 6 shows the actual ejection device.

If the bank official pulls his key 7 again from the key hole 5, the ejection device 14 is moved back to its original position by the spring 15, with the rear end of the ejector device 14 being reinserted into the bolt 2, as shown in FIG. After the whole bolt 2 has been moved to the closed position, the closing bracket 51 can also be lowered to the closed position.

Advantageously, the resilient contact 58 may also be replaced by another reed contact 70, shown in dashed lines in FIGS. 1, 2 and 5.

7 to 10, another preferred embodiment of the invention is shown. Components that are the same or analogous to those in the above-described embodiment of the lock are partially designated with the same reference numbers and, as far as their function is concerned, is the same as above. In this exemplary embodiment, a pivot latch 8.0 is provided at the end portion of the bolt 2 in the lock cavity, which is connected to the bolt 2 by a hinge 81. During longitudinal displacement of the bolt 2, the pawl latch 80 forces this movement. Swing Latch Shape .8.0. and its function is apparent from FIG. 8. The bolt 2 is in the closed position, that is, in the position fully extended to the left. The front end of the bolt 2 protrudes from the lock body 1 and extends into the recess of the door frame (not shown) in FIG. 7 as long as the respective door is closed, as schematically shown in FIG. The pivot latch 80 is pressurized by the spring 82 so that its edge fits into the latch recess 83 thereby preventing the bolt 2 from moving to the right into the open position. The thumb 84 extends into the displacement path of the ejector 14. The ejector 14 is a one-piece and has parallel arms in the U-shaped portion 13, see Fig. 7. If a corresponding bank key 7 is inserted in the key hole 5, the ejector device 1.4 can be moved to the right relative to the bolt 2 so that the ejector device 14 engages the thumb 84 and pivots the pivot latch 80 about the hinge 81. the latch recess 83 and the latch 2 can be moved to the right open position. Upon retraction of the bolt 2 to the closed position, the pawl 80 engages the latch recess 83 again by the action of the spring 82.

An electromagnetic module 8.5 is located in the lock body 1 below the pivot latch 80. This electromagnetic module 85 is provided with a U-shaped core with two upwardly directed arms 86, 8.7. A magnetic coil 8.8 is mounted on the arm 86. The core arm 86 extends upwardly up to the pawl latch 80, the pawl latch 80 abutting the arm 86 ... As long as the magnetic coil 8.8. it is not live, the swinging latch is sliding

8.0 virtually free of friction on the surface of the arm 8.6, without altering the position of the pawl 8.0 because of its preload of the spring 82. If the magnetic current flows magnetically at this point, it forms second bolts 2 to this point secured by the coil latch 80 of Figure 8, whereby at the pivoting position latch, the pivoting latch of the arrow 9.0 and the portion,

Above the latch 2 is a top view of the latch 2 required by both latch voltage to the magnetic coil 88, which is a greater distance, can be released without the use of a bank key 7.

The slider 91 is a sliding movement structurally relative to the displacement.

9.5 and at the rear end partly connected to the elements may however

9.1, shown on is with respect to latch 2, also occur

9.1, with respect to the compression spring 92 T1, the body member is in the form of which lock body 1 is received which presses it against the ends of the spring 92 abutting one91 and its other end is supported. The front end of the bolt 2 has a chamfered recess 97. As is apparent from the recess 97 of the locking body 98 of the lock body 1, the recess 99, 8 is formed in the ball. The locking body 98 can be displaced when the slider and possibly the bolt 2 is moved, but in the longitudinal direction its movement is limited by the two end surfaces or edges 100, 1.0.1. The bolt 2 is formed in this part as solid, so that the locking body 98 is displaced over the upper surface 1.05. gates 2.

FIG. 7, it can be seen that the bolt 2 cannot be moved further to the left, since the locking body 98 limits further movement to the left. In addition, the device is provided with further stops, for example a stop 1.0 in the front of the bolt 2.

When the bolt 2 is in the right open position, as shown in FIG. 11, the sliding member 9.1 remains. in its left extended rest position in which it is maintained by a compression spring 9.2. In this case, the locking body 98 fits into the recess 1.0.3 of the bolt 2. It is not possible to move the bolt 2 to the left because the locking bolt 98 is clamped between the edges 10.0 and 107.

In the open position of the barrier 2 described above, the sliding member 9.1 is present. continue to the left-most position. When the corresponding door, such as a bank security compartment, is closed, the chamfer runs on the door frame and the slider 9.1 moves to the right. This displacement is possible because the bolt 2 is in the moved right position and the locking body 98 can move in the recess 99. The compression spring 92 is compressed.

When closing the lock, the customer moves the bolt 2 to the left with its key 6 until it reaches the position shown in FIG. 12. The slider 91 remains in its locked position in the lock body 1 because it is prevented from moving to the left by the door frame flange 1.08. Only when the shutter also moves to the right when the door is closed and the locking body bends upwards, is it possible to move the bolt 2 to the left into the closed position.

In FIG. 7 shows the position of the individual parts, in particular the sliding member 9.1 and the bolt 2, in which these parts are located if the customer has accidentally moved the bolt 2 to the left into the locked position on the open door.

As already mentioned, the electromagnetic module 8.5 is also provided with an arm 87 extending up to the slider 91. In the forward position to the left of FIG. 7, the slider 91, with its rear end 96, only abuts this arm 8.7. In the forward position to the right, the slider 91 engages both the arm 87 and the core arm 85 through the pivot latch 80.

Thus, in the first position, both core arms 86, 87 are non-magnetic conductive in the region of the slide 91, in the second case when the slide 91 lies above both core arms 86, 8.7, the poles are short-circuited and the magnetic fields are in the slide 91. volumes.

This difference in the magnetic state of the electromagnetic module 85 is readily detectable when the magnetic coil 88 is energized because the current intensity changes. Thus, the position of the barrier can be detected and verified by means of an appropriate electrical or electronic evaluation and control device,.

The electric control and interrogation device according to the invention thus makes it possible to determine from a further location, for example from a bank counter, whether one of the security deposit door is open, even when the bolt 2 is moved to the left in the locked position.

In FIG. 10 is a side view of the latch 2. For better understanding of FIG. In view of the foregoing detailed explanation of both embodiments of the latch lock, a detailed description of this illustration is not necessary.
