The present invention relates to a locking device comprising a lock case and a lock case therefor, comprising a lock case comprising a lock case and a lock case comprising a lock case and a lock case comprising a lock case and a lock case comprising a lock case and a lock case comprising a lock case and a lock case comprising a lock case and a bar pressed by a door pusher, e.g.

In such locking devices, the lock case is usually dimensioned according to certain standard dimensions to fit the standard notches in the doors.

It is an object of the present invention to provide a door lock with a much higher locking security without increasing the dimensions of the lock case.

Another object of the invention is to provide a locking device with better locking security, which, by simple replacement, can replace a conventional door lock, such as a normally constructed cylinder lock or a lock, without the door having to be substantially handled.

Yet another object is to provide an improved locking device that is easily applicable to various applications such as ____ - ... Γ "2,66048 for villa doors, apartment doors, hotel rooms, etc.

The locking device according to the invention achieves these and other objects and is characterized in its broadest form that at least most of the diagonal locking cylinder is arranged in a recess in the thickened part of the cover fitting and that the locking cylinder is arranged by

Since the two separate latch mechanisms are connected to the same locking device in such a way that they can be locked separately, optimal locking security is achieved. A conventional cylinder lock in a door, installed in accordance with current standards, can be quickly and simply replaced by a combined lock according to the invention without the need to make any changes in the door. The master cylinder system of the replaced cylinder lock can then be maintained, if desired, at the same time as additional locking security is provided so that the locking tent can be operated with a special key which, in various individual cases, is only held by a certain person or group of persons. Thus, in the case of an apartment lock, the landlord may have a master key that can be used to affect the oblique tents of the locking devices of all the apartments, while the individual apartment owner alone owns the key for the locking tents in addition to the oblique tent key. The landlord can then prevent the mountain owner from entering the apartment when he or she does not want to.

Instead, when the lock device is used, for example, as a hotel room lock, the hotel manager can hold the keys for the locking tents of all the hotel lock devices. In this case, if desired, certain rooms can be locked so that a person with only a diagonal key cannot enter the hotel room. On the other hand, if desired, both the sloping and locking tents can be acted on from the inside with a single pusher, so that the hotel guest can prevent, for example, a hotel cleaner with only a room key acting on the sloping trolley from entering the hotel room.

In one embodiment, the locking tent is acted upon by a locking mechanism comprising a defective plate. This design is very suitable for both villa and apartment locks, whereby in addition to the sloping roller, the locking bar is also locked by means of a barrier plate mechanism, especially in cases where the villa or apartment is left empty for a long time or if an additional lock is required.

In one embodiment of the invention, the oblique tent can be locked and unlocked at least from the door side provided with a cover fitting, regardless of whether the locking tent is locked or unlocked, and the locking tent can be locked or unlocked at least from the opposite side of the door, regardless of whether the oblique tent is locked or unlocked.

In this embodiment, an additional security device can be achieved by relatively simple means, so that access to the keyhole of the locking roller is blocked from the outside of the door in connection with the locking of the diaphragm. Instead, both locking tents and oblique tents can be acted upon in the usual manner from the inside, whether or not they are locked from the outside.

In a practically preferred construction, in which the cover fitting contains a substantial part and preferably mainly the entire cylinder lock lock cylinder, the lock cylinder is adapted to be actuated by a member in the cover fitting which allows the pusher to be disengaged from the profiled rod when locking or locking.

It is therefore within the scope of the invention to place a part of the guide members on a cover roller which is shaped to be solid and at the same time pleasant in appearance. Thus, certain dimensions of the lock case can be maintained and good operation of both lock mechanisms can be achieved.

In another embodiment according to the invention, the locking mechanism is adapted to operate at least on one side by means of a locking cylinder. This design is especially recommended when the locking device is used as a hotel room lock, in which case the above-mentioned advantages are also achieved. However, it can also be advantageously used as both a villa and an apartment lock.

Although the two axles according to the invention are lockable independently of one another, in one embodiment the locking device is provided with means for engaging the locking mechanisms so that at least on one side both axles can be opened by acting only on the locking frame locking mechanism. In this case, according to a suitable embodiment, the connecting elements can be at least partially arranged in a cover fitting located on the opposite side of the cover fitting containing the locking cylinder.

In this embodiment there are cover fittings supporting both sides of the door, namely that the second, preferably inside the door, comprises said mechanism connecting the two locking devices. In this case, it is most suitable for the coupling members to be acted upon by a pusher mounted on the latter cover fitting, the device preferably being designed such that rotation of the pusher in one direction initially releases the locking axis and further rotation releases the Vinotels.

4,60048

The rear surface of the cover fitting is preferably provided with a cover plate with various notches, for example for guiding the grip and the protrusion in the lock, and with a key hole so that the lock housing can be accessed to act on the locking tent. Additional parts such as a mounting plate, a washer through which the shaft pin of the door pusher is passed, a stop ring and a guide plate are placed on the cover fitting inside the cover plate. The cover fitting is attached to the door by means of a plurality of sleeve nuts passing through the cover plate, which co-operate with screws which have been passed from inside the door through a number of alternative cover fittings.

In practice, it is preferred that the locking bar in the lock case is located above the oblique bar. However, it is conceivable to place the sloping tent on top. It is most suitable that the diagonal bar, as is the case in a conventional lock, co-operates with a securing roller which, when the door is closed, releases the latch hook which locks the diagonal bar. This eliminates the possibility that the oblique bar could be moved to the open position by means of a tool inserted between the side edge of the door and the door frame.

Additional features of the locking device according to the invention will become apparent from the following, in which some embodiments according to the invention will be described with reference to the accompanying drawing.

Fig. Λ is a perspective view showing two main parts, namely the cover fitting and the lock case for the lock device according to the invention.

Fig. 9 shows the cover fitting according to Fig. 8 with the outer shell removed.

Fig. 10 shows the cover fitting of Fig. 8 cut along the line X-X.

Fig. 11 shows the upper part of a lock housing modified with respect to Fig. 2, in which the locking tent is adapted to operate under the influence of cylinder lock mechanisms.

Fig. 12 is a cross-sectional view showing a part of another embodiment in which the locking tent can be actuated both from the inside and from the outside by means of a locking cylinder.

Figure 13 shows a part of the cover fitting modified with respect to Figures 1 and 5.

The locking device 1 comprises a lock housing 2 and a cover fitting 3 on which a door pusher 4 is mounted. The lock housing comprises a sloping roller 5 and a securing roller 6 with its associated mechanisms, shown in Fig. 2 and explained in more detail below, and a locking roller 7 and an associated hamper mechanism controlled by by means of a deterrent key which can be inserted through a keyhole 8 in the cover fitting. The thickened part 3a of the cover fitting includes a conventional locking cylinder 9, by means of which the pusher 4 can be disengaged from the square bar 10.

The oblique tent 5 »securing tent 6 and the locking tent 7 are passed through openings in the fitting 12 fixed to the side edge of the door 11.

The lock case, although including two independent lock mechanisms, has the same standard dimensions as conventional oblique lock locks with a lock cylinder attached to the lock case, respectively, a lock with a press-operated press-axle. The lock case 2 according to the present invention is therefore interchangeable with previously known conventional lock cases without having to make any changes to the door.

Figure 2 shows the main parts of both latch mechanisms. The weight cam 16 placed on the square bar 10 moves the presser to the right of the diagonal roller 5 in Fig. 2 against the action of the spring 17. The securing tent 6 cooperates with the latch hook 19 via an articulated rod 18. When the door is closed, the securing tent 6 protrudes against the action of the spring 20, whereby the rod 18 releases the latch hook 19 so that the oblique tent 5 remains in the locked position and cannot move inside the lock case, e.g. with a tool inserted between the door frame and the fitting 12.

The movements of the locking shaft 7 are controlled by a key inserted into the keyhole 8 by means of a locking plate 21, preferably seven spring-acting baffle plate 22, a locking arm 23, a locking arm 24 and a locking hook 25 which is actuated by a spring 26. The lowest deflection plate rests on the support plate 28.

The mechanism in the cover fitting 3 is shown in more detail with reference to Figures 3 and 4.

The active part 9a of the lock cylinder 9 cooperates with a weight hook 31 which, when the lock cylinder is turned by means of a key (not shown), moves between the two extreme positions shown in Figs. The two fan-shaped notches 31a in the weight cam allow the key of the lock cylinder to be rotated four turns in a conventional manner so that the key can be removed from the lock without affecting the weight cam. Through the pin 31h, the weight cam acts on a latch 32 which is plate-shaped and has a protrusion in the center and a sharp lower end. The latch is adapted to insert the gripper 33 into the notch in the square bar 10, respectively, to engage the pusher 4 and the square bar 10, respectively, to disengage both parts. The upper part of the latch part 32 has an inclined groove 32a into which the pin 34a of the cover plate 34 is inserted, which when the latch moves upwards turns to a position where it covers the keyhole 8. This occurs when the presser is detached from the square bar 10.

The weight cam 31 cooperates with a latch hook 38 rotatably mounted on the latch, under the action of a spring 37, provided with a hook portion 38a which, in the disengagement position shown in Fig. 4, protrudes into the notch 31h in the weight branch 31. The latch hook 38 is further provided with a protrusion 38b guided by a notch 39b in a cover plate (not shown) on the rear surface of the cover fitting.

In the position shown in Figure 4, the protrusion 38b protrudes into the side portion of the notch 39a.

The cover plate is further provided with notches to guide the gripper 33 as it moves.

As mentioned above, the thickened part 3a of the cover fitting forms a housing for the lock cylinder of the cylinder lock. The bottom of this housing is formed in part by a mounting plate, part of which rests against said cover plate. This mounting plate is further associated with a washer which is passed through the shaft pin of the pusher 4 and abuts against a guide plate 41 arranged for the latch 32.

The wrestler is further equipped with a breaking point so that it breaks if it is exposed to excessive violence when the wrestler is disconnected from the square bar.

Numeral 42 denotes notches for sleeve nuts which facilitate the fastening of the cover fitting by means of screws, not shown, passed through a cover fitting (not shown) attached to the inside of the door.

Figures 5-7 show a modified structural twist of a lock device mainly intended for use in a hotel room lock. The main difference compared to the above construction is that the locking tent is adapted to be operated from outside the door by means of a cylinder lock mechanism. For this purpose, the cover arm 1a 'is provided with a notch 4-5 lock for the cylinder 46 instead of the keyhole 8 shown in Fig. 1. In this embodiment, a pusher 61 is connected to the locking tent from the inside of the door, which is connected to a rectangular bar 4-8 passing through the lock housing 2 '. The pusher 61 is mounted on a cover fitting 60 attached to the inside of the door, which includes certain control members, which will be described in more detail below with reference to Figures 8-10,

As stated above, the rule must be that only the key belonging to the lock cylinder 46 is available to the hotel management. Thus, this lock cylinder cannot normally be influenced from the outside. The cover sleeve 5 'is therefore provided with a notch for the cover plate 51, which normally covers the lock cylinder. In Figure 5, the plate is provided with a number, preferably the room number in question, but the plate 51 may, of course, be marked in some other way or, if desired, be unmarked. The cover fitting 5 'is further provided with a marking opening 52, in which a marking device 56, 57 cooperating with the locking roller indicates when the door is closed from the inside. This is at the same time a sign for staff who cannot enter the room by using the lower lock cylinder 9 ', for example by means of a master key suitable for all doors.

If, on the other hand, the hotel management, for example, wants to prevent anyone from accessing the to the room, the cover plate 51 is removed, after which the locking tent is slid into the lock cylinder 46 by means of a special key suitable.

Figures 6 and 7 illustrate how the interiors of the cover fitting 5 'are shaped. Compared to the embodiment shown in Figures 5 and 4, it differs in that a separate cover plate is not required for the top keyhole, as such is not the case. In this embodiment, the weight cam 31 'is provided with teeth 31'a which engage the corresponding teeth in the movable locking slide 32', the lower end of which slider surrounds a gripping element 33 'which protrudes out of the notch in the square bar 10, respectively, as explained in Figures 3 and 4. connection - _ - r .......- 8 66048 desta.

The weight cam 51 'remains in both its extreme positions by means of a torsion spring 50'. Numeral 54 'denotes a guide plate for the gripping element 55'. 55 'means back cover plate for cover fitting.

Figures 8-10 illustrate the cover fitting 60 inside the door with its associated parts. The fitting is provided with a pusher 61 which, as described below, allows the locking mechanism of both the locking roller and the inclined roller to be actuated. Hela located in the rear surface of the base plate 62, which is connected to the outside of the peitehe-Laan 65 with four screws.

The upper square shaft 48 forms a steering shaft for the locking mechanism of the locking roller 7 'shown in Fig. 11.

The shaft 48 has a weight cam 65i provided with a roller or pin 66 which acts on an intermediate arm 67 which is mounted at its center on a pin 68. At the lower end of the intermediate arm 67 there is a tooth segment 69 communicating with a corresponding tooth segment 70 on the lower square bar 10 '. having a lower end cooperating with a latch member 72 for holding the weight cam in either of the rest positions.

When the pusher 61 is rotated so that the rectangular axis 48 shown in Fig. 9 moves clockwise, this acts on the locking mechanism shown in Fig. 11 so that the locking bar 7 'moves to the locking position.

When the pusher 61 is rotated in the opposite direction from the locking position, the locking bar 7 'initially moves to the release position, after which further rotation of the pusher causes the weight cam 65 to act on the lower square bar 10' through the spacer arm 67 and both tooth segments 69, 70.

It can be seen from Fig. 11 that the movement of the locking roller 7 'through the tooth segment 80 is controlled by a toothed cylinder weight cam 81, which is acted either by the lock cylinder 46 (Fig. 7) or on the opposite side by the presser 61 square bar 48.

The tooth segment 80 is provided with a pin 80a which engages a link groove 7'a at the rear end of the locking roller 7 '. The movements of the locking axle take place against the action of the spring 85.

Figure 11 shows only the upper part of the lock case 2 '. The lower part provided with a bevel can be shaped mainly as shown in Figure 2 or it can be of a different shape depending on the requirements in question. The securing tent 6 can then, for example, be located closer to the oblique tent 5. 6 j0 4 8

Figure 12 illustrates a variation of the embodiment of Figure 7. In this embodiment, the locking tent is adapted to be acted on both externally and internally by a separate locking cylinder 46 ', 90'. In this embodiment, there is no cover fitting on the inside, which allows the diagonal roller mechanism to be actuated. Instead, it is acted upon in a conventional manner by a pusher placed on the lower square axis. This design is especially intended for use on the exterior doors of villas and apartments. The same key can fit into the upper locking cylinders of the molepe, but if desired it is of course possible to make the same key also fit into the locking cylinder located in the cover fitting 3. The lock cylinder 9 can preferably be formed as a master key cylinder, the master key of which, however, does not fit into the upper cylinders 46 ', 90'.

Fig. 13 shows the upper part of the outer cover fitting 3 "suitable for use in the locking device according to Fig. 12. This cover fitting differs from that shown in Fig. 5, inter alia, in that there is no sign window, and the fitting lacks means for placing the cover plate on the upper lock cylinder. fittings mainly look like each other.

In all the embodiments discussed above, the locking tent with its associated latch mechanisms is located at the top of the lock housing. Alternatively, the oblique tent with its latch mechanisms can instead be placed on top. Many other variations are possible within the scope of the invention. Thus, for example, the diagonal roller securing device may cooperate with an automatically locked latch mechanism designed in a different manner than in the embodiment shown. The rod tent 6 can thus be arranged higher than in Fig. 2, i. closer to the inclined roller 3 »and the securing roller can also be located between the inclined roller 3 and the locking roller 7. Accordingly, in another embodiment, the locking cylinder 9 is only partially inside the cover reflection, which can then be embedded in the door in order to further limit the part of the cover fitting projecting from the door.

The invention also makes many other variations possible within the scope of the basic idea defined in the appended claims.
