- a part 10 of the locking shaft 5, which is so arranged as to be a ⁇ acent tc the aforementioned locking recess 6, is so arranged as to interact with a part 11 of the lock bc ⁇ 3 projecting inwards towards the mouth part 8 c the loo- opening 7 m the aforementioned locking position I.
- the end part 5A of the locking snaft 5 exhibits the aforementioned locking recess 6, which is formed preferably by an approximately perpendicularly executed V-shaped recess m a circular shaft 5.
- the angle of the opening is preferably ca. 72°, although other angles are also possible.
- the aforementione ⁇ shaft 5 is so arranged as to be caused to rotate through the interaction between the aforementioned locking recess 6 and the lock opening 7 m the locking shaft 5 and m the lock bolt 3.
- the aforementioned device 1 is so arranged as to function as a lock on a flap or a door for the removable storage boxes m a bank vault in order to lock the door in a position enabling the boxes concerned to be locked securely m the intended secured position I.
- the lock 2 is so arranged as to function electrically and comprises a coil 13 ana a core 14 interacting therewith and a lifter 15 for the core 14.
- the aforementioned lifter 15 is capable of actuation by a cam 16 attached to the locking shaft 5.
- the component parts included m the lock 2 are so arranged as to be accommodated m the space 22 formed between two mutually opposing and mutually connecte ⁇ base plates, namely a lower base plate 20 and an upper base plate 23, for example by means cf fixing screws 24, ana with a spring- assisted sensor arm 25 accommodated between 22 the two base plates 20, 22, ana with an end part 25A m tne aforementioned sensor arm 25 projecting frorr the for e ⁇ flap 26.
- the two base plates 20, 23 preferably consist cf plastic material, preferably essentially a material such as acetal resin or some other polymer plastic.
- the aforementioned two base plates 20, 23 form an openable and lockable flap 26 for a bank vault compartment.
- a lock capable of being actuated by the customers concerned, which is not shown here but is connected to the bolt 3 to enable it to be actuated m such a way as to be displaced, i.e. to rotate freely, and m so doing to interact with the lock bolt 3 and enter into engagement with the locking shaft 5.
- the aforementioned bolt 3 is so arranged as to move into engagement with the locking shaft 5 m order to achieve closure of the lock 2, m conjunction with which the aforementioned lifter 15, which is intended to be capable of interacting with the core 14, is so arranged as to be lowered towards the locking shaft 5.
- the core 14 is so arranged as to drop down into a seat 27 arranged m the locking shaft 5 and, m so doing, to indicate that the lock is in the closed position.
- the aforementioned bolt 3 can be formed by a single piece or by pairs of jointly embossed components 3 1 , 3 , and m the illustrative example the embossings 28 are situated at three points separated from one another by a certain distance .
- the lock 2 comprises a manually actuated bar 29, which is capable of connection to a rocker device 30 attached to the core 14.
- the aforementioned rocker 30 is so arranged, m conjunction with manual actuation of the bar 29, as to actuate the lock 2 so that it is capable of being opened manually .
- Fig. 3 which shows the lock 2 in the locked position, ana with tne upper cover plate removed, the ooenmg frequency with tne lock 2 activated is as follows:
- 3ctn contact points are closed, and a scanning current is present m the coil 13, although this is not high enougn to "stick" the core 14 and the anchor plate 31 together. It is possible to pass a current through the coil 13 in this position.
- Actuation via a customer lock mounted m a flap 26 of the kind m question causes the bolt 3 to be displaced and to be drawn into the flap 26.
- the bolt 3 engages with the locking shaft 5, which rotates m a clockwise direction m conjunction with the displacement of the bolt 3.
- the cam on the periphery of the locking shaft 5 raises the lifter 15 for the core 14, which m turn takes the core 14 with it via the anchor plate 31.
- the lifting height for 20° rotation of the locking shaft 5 is ca . 1.7 mm.
- the lower locking part of the core 14 is situated above the periphery of the lockm ⁇ shaft 5 and permits continued rotation of the locking shaft 5 past the locking point on the shaft.
- a breaker plate 32 m a micro switch changes position and breaks the contact witn a contact plate 33.
- the front breaker plate 32 is actuated by the movement of the core via a rocker 34 and the breaker rocker 30, m conjunction with which the current loop is broken and the current tc the coil 13 falls.
- the core 1- releases the anchor plate 31 and positions itself at the top cf the locking shaft 5, in conjunction witn which the compartme-t is indicated as being oper .
- the tota_ rotational movement cf the locking shaft 5 is ca. 100°.
- the flap 26 is opened, and the flap sensor 25 retracts out the way with spring assistance, ana the contact point between the front contact plate 33 and the upper contact spring 35 is broken.
- a closing sequence for the aforementioned lock 2 is as follows: Lock closing sequence:
- the flap 26 is closed, m conjunction with which the flap sensor 25, 25A forces m the front contact plate 33 against the upper contact spring 35, m conjunction with which the front contact point is closed.
- the loop remains broken, however.
- the bolt 3 is moved to the closed position via the customer lock.
- the bolt 3 engages with the locking shaft 5, which rotates m anti-clockwise direction, synchronously with the movement of the bolt 3.
- the lifter 15 for the core 14 is lowered m time with the rotation of the locking shaft 5. After rotation of the locking shaft 5 through 80°, the core 14, which is lying on top of the locking shaft 5, drops down into a seat 27 on the periphery of the locking shaft 5.
- the breaker plate 32 changes position, m conjunction with which the loop is closed and the compartment is indicated as being closed.
- an opening attempt with a non-activated lock is as follows: Opening attempt with a non-activated lock:
- Both contact points are closed, and a scanning current is present m the coil, although this is not high enough to "stick" the core 14 and the anchor plate 31 together.
- a significant aspect of the invention is the function cf the micro switch to ensure the security of the design. In order to ensure that the switch switches on and switches off m such a way that open/closed is indicated with
- the micro switch has built-in hysteresis of ca. 1.5 mm. This is the difference between the switchmg-on point and the switchmg-off point
- the micro switch is so arranged as not to switch on before the shaft 5 has been rotated through at least ca. 20°. When switching takes place, the core 14 is unable to drop back down into its recess 27 m the shaft 5.
