The lock rosette (3) is screwed in place at the other side of the door, with projections (14) aligned towards the housing at its inner side (13) to key into the polygonal opening through the door.

Description

The invention relates to a lock with a lock housing and an arranged therein latch operated by a locking cylinder.

Such locks are known in a variety of embodiments. The mechanical and constructive structure is usually very complex, which is why the castle with the lock housing and the mechanical components arranged in it is delivered pre-assembled. The components of the castle almost always exist made of steel or sheet steel, to meet the frequently required mechanical strength to achieve violence.

In contrast, the invention aims to provide a lock, which is made up of just a few parts and is therefore special easy to assemble, taking on the aspect of durability less value should be placed against the use of mechanical force.

• aus Kunststoff besteht,
• die Form eines zum Türblatt hin offenen Kastens aufweist und sich mit seinem die Öffnung umgebenden Gehäuserand auf der Innenseite des Türblatts abstützt,
• mit an seiner Innenseite angeformten Führungen für den Riegel versehen ist,
• mit einer von der anderen Seite auf das Türblatt aufgesetzten Rosette verschraubt ist, an deren Innenseite zu dem Schloßgehäuse hin weisende Vorsprünge angeformt sind, mit denen die Rosette formschlüssig in eine mehreckige Öffnung des Türblatts eingreift.

For this purpose, it is proposed in a lock of the type mentioned that the lock housing

• is made of plastic,
• has the shape of a box open towards the door leaf and is supported on the inside of the door leaf with its housing edge surrounding the opening,
• is provided with molded guides for the bolt on its inside,
• is screwed to the door leaf from the other side by means of a rosette, on the inside of which protrusions are formed which point toward the lock housing and with which the rosette engages in a form-fitting manner in a polygonal opening in the door leaf.

Advantageous refinements of such a simple structure and from only A few parts of the lock which can be easily assembled are in the subclaims specified.

It is proposed with a preferred embodiment that on pivot bearings, which are integrally formed on the inside of the lock housing, rockers are pivotally mounted, each eccentric to the pivot bearing with the end a locking rod can be connected, and that the rockers through the bolt are operable. Because of this design, the lock can also be used equip the rockers, in which the ends of locking rods can intervene, turning the lock into a bar lock is upgraded. If this additional function is not desired, the Rockers simply left out when assembling the lock, which then causes that Lock becomes a normal latch / deadbolt lock.

If the lock is used in the version as a bar lock, the Actuation of the rocker by the bolt, preferably by one on the Bolt-shaped pin, which protrudes into an opening of the rocker, wherein the opening is arranged eccentrically to the pivot bearing of the rocker. Preferably each of the rockers, like the lock housing, is made of plastic.

With a further embodiment it is proposed that the lock housing has weakened wall areas on its housing edge, the can be broken out without destroying the rest of the plastic housing. The housing is therefore not in view of the different possible uses provided with openings for the passage of the locking rods. Rather, these openings are made if necessary in that a Correspondingly weakened wall area on the edge of the housing the plastic housing is broken out.

The lock housing and rosette are preferably positively connected to one another, by forming cylindrical on one of these two components Spigot without play in cylindrical formed on the other of these two components Extend the receiving openings. This will make it simple, however for the intended purposes completely sufficient form fit between the lock housing made of plastic and also preferably plastic rosette reached. The positive connection opposite The opening in the door leaf is indicated by the ones already mentioned formed on the inside of the rosette projections with which the rosette engages in the opening of the door leaf. Because the fixation in the door leaf only done by the rosette, there are no measures on the lock housing itself required to e.g. to avoid twisting in relation to the door leaf. This allows great freedom in the design of the lock housing Plastic.

With a further embodiment of the castle it is proposed that the Pin on the inside of the rosette, and the receiving openings on the inside of the lock housing. Preferably, the inside of the lock housing with sleeves formed there, the inside of each Pick up the corresponding pin of the rosette and with the outside of the Keep bars. In this embodiment, therefore, with the sleeves and the same component is used to on the one hand the connection between To effect lock housing and rosette, and on the other hand that in the Lock housing arranged to lead latch.

Preferably, the screw connection connecting the lock housing with the rosette through the receiving opening and a partial length of the pin.

It is also proposed that the rosette be square, including the projections formed on it are also rotated by 90 ° to form a rectangular one Opening of the door leaf can be placed.

In order to be able to use the lock universally in the outside area, too a variant one clamped between rosette and door leaf, with one articulated stored cover for the rosette provided rain protection rosette proposed. The attachment of the hinged cover of the rain protection rosette is preferably carried out in the form of a flap which can be pivoted upwards.

Another variant of the castle is characterized by one on the The outside of the rosette is located next to the opening for the locking cylinder Slider, which is connected to the bolt. The slide serves to actuate i.e. the withdrawal of the latch, however, this actuation is only then released if the bolt is unlocked first with a key, and then there is the possibility of locking the latch by means of the slider withdraw.

Another embodiment is characterized by a in the lock housing arranged detection element for the position of the bolt. Alternatively or additionally can be arranged in the lock housing detection element for Position of the actuating cam of the lock cylinder can be provided.

Another preferred embodiment of the castle is characterized by one arranged in the lock housing, with an electrical lighting element provided electrical circuit board with connections for at least one detection element. The status of the lock is detected by means of the detection element, and displayed by means of the lighting element preferably arranged on the circuit board. In this way, it can be seen from a distance, in what status the castle is currently located.

For transmission of the light signal generated by the electrical lighting element is a first embodiment characterized by at least one light-guiding Component between the light element and an opening in the rosette. To do that to be able to recognize the light signal emitted by the lighting element, if the rosette e.g. through the cover of the optional rain protection rosette is covered, with a further embodiment, at least one light-conducting component between the lighting element and an opening in the Rosette closing cover suggested.

In Figures 1 to 3 is the lock left or right usable in shown in its entirety and in assembled condition. The castle is in one rectangular opening 12 fastened in a door leaf 1 and consists of a total three main components, namely a box-shaped lock housing 2 Plastic, a rosette 3 and one arranged in the lock housing Latch 4, which is not actuated with a latch section 5, preferably with it integrally formed bevel 6 protrudes from the lock housing 2. The bolt 4 and the rosette 3 are preferably also made of plastic. at assembly of the lock, the lock housing 2 with the rose 3 screwed, for which purpose three screw connections 7 as shown in FIG. 1 are inserted through the lock housing 2, which with their other ends in engage the appropriate thread on the rosette 3. According to Figure 2 is additional to the rosette 3, which is provided with the opening for the locking cylinder 8, one Rain protection rosette 9 provided. Part of the rain protection rosette 9 is a Cover 10 pivotally mounted thereon in the manner of a flap.

In the sectional view in FIG. 3, the part of a door frame 11 is also shown, behind which the bolt section 5 of the lock is locked.

Details in the structure of the castle are given below with reference to the figures 4a, 4b, 5a and 5b, which each show the castle in a perspective exploded view show, each from a different perspective.

First, it is explained how the fastening of the lock in the opening 12 of the Door leaf 1 is done. For this purpose, as can be seen in FIGS. 5a and 5b the inside 13 of the rosette shaped in the form of a plate has three projections 14 integrally formed, with which the rosette positively into the opening 12 of the door leaf intervenes. In this way, the rosette 3 cannot face the door leaf 1 turn as soon as the rosette 3 is placed on the door leaf. On the inside 13 the rosette 3 are also molded cylindrical pins 15. These contribute Assembly of the lock without play in appropriately designed sleeves 16, which on the Back wall of the lock housing 2 are integrally formed. These sleeves 16 are best seen in Figures 4a and 4b, since these drawings one Allow view inside the lock housing 2. In the embodiment the number of pins 15 or sleeves 16 is three.

Figures 5a and 5b also show that the rosette 3 on its the Door leaf facing underside is provided with a circumferential step 17. This stage 17 serves to fix the rain protection rosette 9 in a form-fitting manner, by additionally clamping the rain protection rosette 9 between rosette 3 and door leaf 1 or clamped. In this way, it remains the user's choice whether the rain protection rosette 9, e.g. for the use of the lock in Outside, want to assemble or not. The rain protection rosette 9 is, as well like the rosette 3, designed square, so that both rosettes in each 90 ° rotated position mounted on the rectangular opening 12 of the door panel 1 can be.

The lock is also extremely universal in terms of the thickness of the door leaf 1 the door leaf 1 is shown very thin in the drawings, e.g. it can be here act as a control cabinet door made of sheet steel. An adaptation to others Door leaf thickness is easily possible by in such a case Pin 15 of the rosette 3 less far into the sleeves 16 of the lock housing 2 protrude, however the necessary positive locking has been achieved. Just one Adjustment in the screw length of the three screw connections 7 is necessary.

Details of the lock housing 2 are explained below, these Details are best seen in Figures 4a and 4b. The lock housing 2 consists of a rear wall 18 and arranged almost all around Side walls 19, which are only an opening 20 for the passage of the locking section 5 leave blank. The lock housing 2 is completely open towards the door leaf, i.e. the side walls 19 enclose an open housing edge 21. With this housing edge 21, the lock housing 2 is supported on the door leaf 1. There is none Adaptation of the shape or structure of the housing edge 21 to the opening 12 of the Door leaf 1. In this way, the lock housing 2 can also be used if the shape and shape of the opening 12 of the door leaf are different than in the illustrated embodiment. In this case, the Rosette 3, but not that with its edge 21 only on the outside the lock housing supporting the door leaf 2.

The sleeves already described are integrally formed on the rear wall 18 16. Not only the hole serving as a receptacle for the pin 15 Sleeves 16 is cylindrical, but also the outside of the sleeves 16. On this Way, the sleeves 16 also serve as a guide for the slidable in the Lock housing 2 arranged bolt 4. The bolt 4 is a relatively complex plastic injection molded part with slot-shaped guides 22, 23, which each extend parallel to one another. The two point slot-shaped guides 22 of the same length, whereas the middle arranged further slot-shaped guide 23 to one side of the bolt is open. Each of the slot-shaped guides 22, 23 takes a sleeve 16 of the lock housing 2 with little lateral play, thereby guiding the Latch 4 is effected in the lock housing 2. On the inside of the Lock housing 2 are finally two pegs formed as a pivot bearing 24 serve for rockers 25 which can be placed on the pins. The rockers 25 are made of plastic. Additional locking rods can be used by means of the rockers 25 Actuate 26, the ends 27 in eccentrically arranged Engage openings 28 of the rockers 25. The openings are to compensate for the game 28 in the rockers 25 designed as conical slots to avoid the otherwise occurring To prevent transverse displacement of the locking rods 26. Finally is each rocker 25 with another eccentrically arranged Provided slot opening 29 into which a pin 30 of the bolt 4 engages.

The figures best serve the function of the rocker 25 as a transmission element 6a and 6b recognize. Each rocker 25 rotates about the pivot bearing 24 of the lock housing around, the pivot bearing 24 thus forms a fixed point. In the event of a shift of the bolt 4, this takes the rocker 25 with its pin 30, and pivots this. As a result, the engaging in the openings 28 of the rocker 25 Locking rods 26 moved outward from each other. Figure 6a shows the bolt and the locking bars in the retracted state, Figure 6b the same parts in the locked state. Here, the bolt 4 sets the Stroke h back. Springs 31 cause the bolt 4 in in the unactuated state moves to its locked position. Can be clearly seen in FIGS. 6a and 6b also those slot-shaped guides 23, via which the rule 4 on the not shown sleeves of the lock housing is guided longitudinally.

In the following, likewise with the aid of FIGS. 6a and 6b, the actuation of the Bolt 4 explained about the locking cylinder 8. Fixing the lock cylinder 8 takes place several times, namely through a corresponding recess in the Lock housing, via a corresponding opening 32 in the rosette 3, and by means of a screw through the lock housing. The locking cylinder 8 projects through one of the two openings 22 of the bolt 4. The openings 22 are arranged symmetrically, so that left and right mounting of the Castle is possible. These openings 22 have recesses for the Actuation cam 34 of the lock cylinder 8. Every recess is after above by the locking lug 33a, and down by the opening lug 33b limited against which the actuating cam 34 of the lock cylinder 8 can be moved is. According to FIG. 6a, this results in the bolt 4 being pushed in or pulled back. If the actuating cam 34 is moved back into the basic position, it moves the latch 4 again in its closed position. The lock is on Latch lock, the bolt 4 is moved back by springs 31.

By means of an electrical detection element 35 shown in FIG. 6b check the position of the actuating cam 34. The detection element 35 is arranged fixed to the housing and is in electrical connection with a control and switching board 36 also arranged in the housing the control and switching board 36, which with an electrical connector 45 is connected, there is an electrical lighting element 37, which by a corresponding light signal indicates the status of the bolt. this happens preferably in such a way that the lighting element 37 lights up when the bolt 4th is unlocked.

So that the optical signal of the lighting element 37 can also be recognized from the outside, from there lead light-conducting components 38 into an opening 39 of the rosette 3 as well as further light-conducting components 38 into an opening 40 in the cover 10. Details of the arrangement of the lighting element 37 and the two light-conducting Components 38 can best be seen from the sectional view in FIG. 3.

The lock is suitable, either a single lock cylinder 8 or how this is shown alternatively in FIG. 8, two parallel locking cylinders 8 take. In this way, the lock is used for different purposes suitable, e.g. 8 different, i.e. use different keys. Differentiate between the possible functions as follows:

First, an OR function is possible. There are two in the lock different locking cylinders belonging to different locking groups. To the left cylinder e.g. the caretaker has access with his key the right lock cylinder e.g. a person responsible for maintenance work is.

An AND function is also possible: Here, e.g. the right lock cylinder for "closing", i.e. the bolt of the lock is unlocked. In this Status can then be the key holder for the other, namely the left one Lock cylinder open the lock. In this way, a "four-eyes principle" is realized, in which an opening of the lock is only possible when owners of two keys work together. The respective status of the The lock can be made visible via the light element 37.

On the other hand, as shown in FIG. 7 and also all FIGS. 1 to 6b, is merely a lock cylinder 8 inserted into the lock, which is otherwise for the second Lock cylinder provided parallel space free. In the illustrated Exemplary embodiment, the lock is constructed as a latch lock. Are locking lugs therefore not available. In this case, one is placed on the parallel place by hand actuatable slide 41 arranged. This is in the rosette 3 in the longitudinal direction displaceable. At the back is the slide 41 with a transmission element 42 connected, which engages positively in the bolt 4. On in this way, the latch 4 can be actuated manually by the slide 41 pull back and unlock the door. However, this is only possible if the lock is first unlocked. This is done by Key actuation of the locking cylinder 8. Only then can the Slider 41 actuated and thus the bolt 4, optionally including the Locking rods 26 are withdrawn. The position of the bolt 4 leaves check themselves here also by means of an electrical detection element 43 and if necessary, display by means of the lighting element 37 for checking.

For passing the locking rods 26 through the lock housing 2 indicates the lock housing weakened wall areas 44 its case edge 21 on. These wall areas 44 are without destroying the remaining plastic housing can be broken out. In this way the lock housing 2, if the locking bars are not installed, closed on all sides.

If the lock described is made of plastic in all important parts the lock cylinder 8 is electrically insulated from the door or the interior.

FIG. 5b shows a protector plate which is triangular in the exemplary embodiment shown, which is penetrated by the screws of the screw 7. The Protector plate in combination with one also allows in this case Metal existing rosette 3 a significant increase in mechanical Resilience of the lock against violence.
