APPLICATION FOR UNLOCKING ELECTRICITY

The invention relates to an arrangement as defined in the preamble of claim 1 for unlocking an electric lock using a key.

Electric locks having a standard key-operated door-mounted part including a movable locking tongue are known in the art. The counter part in the frame is constructed so that its blocking effect can be eliminated by an electric actuator. The locking edge of the counter part can be displaced or pivoted, e.g. by means of an electromagnet, so that even in the extended position the tongue of the lock can come out of the jamb and the door will open.

Such solutions are not suitable as a security lock, as the locks are easily breakable. In particular, the barrier edge of the frame counterpart can be forcibly turned aside.

The object of the invention is to provide a locking arrangement which is particularly suitable for security doors and vaulted doors, whereby the lock parts in both the door and the frame are in close proximity to the inner surface of the door or wall and can be unlocked by a key. Further, it has been made difficult or impossible to open the lock with the wrong key or other key. with a heavy breaking device.

The invention according to the invention solves the problems and disadvantages which have arisen, and the arrangement according to the invention is characterized by what is stated in the appended claims.

An advantage of the invention is that the same lock is normally an electric lock, e.g. with code opening and time delay, and can be unlocked with a key during a temporary idle period. The locking can be rationalized to seal the door ·; ··· so that the movement of the latch portion of the lock causes the door to be pressed against the seal. Breaking the lock from the keyhole is particularly difficult and the design of the lock is made to resist the various tools used in break-in situations. The lock is located inside the security door so that only the 2 holes of key 106970 are visible from the outside. However, with the right key, the lock can be unlocked fairly quickly. The structure of the lock is relatively simple despite being electrically and key operated.

In the following, the invention will be explained in more detail with reference to the accompanying drawing, in which

Figure 1 is a sectional view of the lock assembly at the door.

Fig. 2 shows the closing member obliquely.

Figure 3 shows a drawback plug.

Fig. 4 shows a front plate conveying the opening movement.

Figure 5 is a front view of a securing plate.

Figure 6 shows a partially cut away key.

Fig. 1 shows a lock assembly disposed in the door, comprising a frame part 1, which is fixed to the door from the inside (in the figure to the right of the door). On the left side of the frame there are threaded holes 19 and 20, through which also the key is inserted into the lock if necessary. When the lock is electrically operated, the holes 19 and 20 are normally plugged with a safety plug such as the plug 23 of Figure 3. The plug has a special shape ·; ··; recess 26 to open it. The threaded portions 19 and 20 are of a different hand, whereby the plugs therein must be able to rotate in the right direction to remove them and not damage them. Thus * * ·. _; that is, a burglar-driven burglar damages the plug so that it cannot be removed. • · · l / normally unlocking the key with the key removes the malfunctioning plugs 23 by turning them with the special key • · · * · * * in the correct directions of rotation. The plugs and threads may have a plurality of similarly shaped recesses 26.

·· ♦ • ♦ · • · ·

Next, the body portion has an opening 25 through which the right key passes through. The aperture is shaped per key.

Inside the body part 1 there is also a closure member 10, the movement of which in the formed housing is secured by ball bearings 21. The closure · *: ··; the member 24 is normally electrically rotated between the locking and unlocking positions by electromagnet 24, for example, as shown in Figure 2. Magnet 24 is pulled by a ferromagnetic piece 22, rotating the closure member about 90 ° and pushing the polarity reversing.

3, 106970

The closure member has an angle 27 away, so that the housing has a stop piece as a motion limiter at a corresponding point.

If the closing member 10 is rotated by the magnet 24, the securing plate 9 must first be pulled to the right against the springs 8 by the second magnet (not shown in Fig. 1) so that the plate 4 and the closing member 10 can rotate.

When the closure member is rotated by means of a wrench 16, a distance-adjusting ring 3 or no ring 3 is firstly attached to the closure member 10 and, in addition, a plate 4 for releasing the opening movement. . The edges of the forming hole are sharp because the rotational force is low and the use of the key 16 is only temporary, whereby the sharp edges of the hole are capable of transmitting the rotating force to the plate 4 and the closure member 10 without wear. In addition, the breaker is easily damaged by the hole 12 and subsequently the rotation of the closing member 10 through the hole 12 is not possible. The plate 4 further has holes 11 'closer to the periphery for the pins 13 of the securing plate 9:: (Fig. 5).

·. The arrangement includes a back cover 2 to which a securing plate 9 is secured by a flange 5. The securing plate 9 is able to move ... in the direction of the key line on the pins 7. The spring 8 pushes the plate so that it tends to be against the plate 4, so that the pits 13 are in the pits 11 of the plate 4. Since the plate 9 is non-rotatable, the closure member is 10 in that case also locked to your bike • • · V. The plate 9 includes holes 14 for pins 7 and a central hole 15 for pins 6.

• · • ♦ · • · ♦. 1.1 If the key is correct and inserted into the hole as far as it will go, the end of the key 16 of FIG. 6 pushes the locking plate 9 to the right before the key is received and the plate 4 is released from locking. The end of the key 16 must have a sleeve portion 18, since the lock assembly includes a pin 6 which prevents the unlocked key from entering. Pin 6 also prevents the drill bit from staying in the centerline if the breaker drills the keyhole completely. The pin 6 pivots the drill bit to the side of the drill line and the opening 12 of the plate 4 4 106970 becomes eccentric.

The key 16 of Fig. 6 comprises at its simplest point at one point the contour wings 17, the sleeve portion 18 at the key end and the distance x from the key to the contour wings 17. The distance x is an important measure. at hole 12 of plate 4 to allow the key to rotate. The thickness of the adjusting ring 3 or its omission gives different distances x. The key may have additional shapes, but in the key rotation situation they may not be exactly at the shape opening 25 of the body part 1 if the opening shape does not allow the key rotation.

The bolt assembly is fully installed in the door from the other side of the door, wherein the cracker are not visible from the outside avaimenrei-Ka. The structure of the lock cannot be deduced from the outside either.

In the larger locks, the closing member can also be moved, for example, by means of an electric motor rotating in both directions and a helical gear, for example, the outer edge of the closing member has a tooth - *: ··: for the helix. At the same time, the worm gear locks the closing member in all positions. In the non-electric case, the opening is accomplished by inserting the key (special key) as shown in Fig. 1 through the plugs 23 and the special openings 25, • ♦ «λ. however, not to rotate the closing member "** * directly by means of the plate 4, but first to rotate the gearwheel and through it the closing member.

Adding different nuts, different nuts and complicating the key respectively makes locking impossible with key imitating deeds.
