EP0995866B1 - Lock, in particular espagnolette lock - Google Patents

Abstract

The mortise lock, with an operating rod link to other lock units, has at least one spring bolt (27) which is moved outwards by a spring (41). It is moved by a locking unit (33) into an initial projected position where only the section (A) with the end chamfer (28) of the spring bolt head extends beyond the lock plate (1), to be held by the released locking unit (33). The spring bolt (27) can be extended into a second position which brings the body section (B) of the spring bolt (27) through the lock plate (1). The locking unit (33) is released by the retraction of the spring bolt.

Description

The invention relates to a lock, in particular espagnolette lock, with at least one of a falling spring in front of the case, which in a first trap position, in the substantially only a case slope portion having the case slope overhanging the forend, from a releasable one Locking member is held and out of this first Fallenvortrittsstellung after Fallenrückverlagung and Release of the locking member until a second case trailing position extends, in which a the trailing edge subsequent bar section in front of the forend occurs.

It is known from EP 0 431 369 A2, such Trap control to provide a mortise lock. The Trap has one there to the case head end face reaching longitudinal groove for receiving a lever-like Locking member, which in the first case trailing position with a locking cam protrudes behind the forend and so that the further advance movement of the trap is blocked. Pulling in on their open position Door causes the door frame-side strike plate a retraction of the trap, wherein the locking member of its blocking position comes to the trap and aligned Alignment of trap and closure engagement opening of the strike plate the forward displacement of the trap in the second trap position allows. This solution is disadvantageous. When painting the door can in the Longitudinal groove of the trap entering color to immobilization of the locking member, so that the closing function is no longer guaranteed. Also are manipulations on the locking member with the door open.

Furthermore, the strike plate on the design of the Trap carefully matched and mounted.

A similar trap control mechanism is also included an additional lock of a drive rod lock known see. DE 296 05 517 U1. Again, the pre-pictured Disadvantages.

In contrast, the invention has the task a lock, in particular espagnolette lock, the type in question in a simple manner closing technical improve.

This task is initially and essentially at a lock with the features of claim 1, wherein it is pointed out that the release of the locking member associated with the fall-back movement.

According to such a configuration is a lock of in Speech-standing species, which is used both and closing technology is improved. One is up to the case head end surface reaching locking member not intended anymore. This means that an immediate Interaction of locking member and strike plate not available. The release of the locking member is now associated with the trap retraction movement, the trap even the tactile element represents, in the case of the trap retraction movement the locking member in the release position control what happens then the precedence of the trap in the second Fall occurrence position permits. The locking member is located Himself in a hiding place, so inside of the lock housing, and is from the outside of the door not accessible. Manipulations on the locking member are not presumable. Then you can paint the door also to no binding of the locking member to lead. Furthermore, there is a contamination in the blocking member moving area largely prevented. According to the invention it is provided that the locking member according to inclined edge control from its blocking position into a release position is shifted, in which the locking member is held. The means for shifting the locking member from the blocking position out into the release position are therefore easily manufacturable, which helps Save manufacturing costs. Once at Retraction of the trap via the inclined edge control the Locking member from the locked position to the release position is brought, care is taken that the Locking member not accidentally get into the locked position can. In detail, the procedure is that the held in the release position locking member according to Lever action on a push-button or alternately operated Fall retreat for entry into the locked position is resolved and in the following case retreat in the Lock position occurs. To the trap in its first trap position safe to hold and yet to ensure the modulation of the locking member is the locking member as provided with a pawl head Lever formed. Then has the pawl head a control slope and engages in a locking recess of the latch tail in the locked position. About the control slope is at the closing plate related Fallenrückschub the pawl head from the locking recess dug into the secured release position. This then allows the precedence of the trap over the first trap position out into the second Trap position, in which the trap with her Latch section in front of the forend and into the trap engagement opening of the strike plate occurs. To the locking member is secure in the release position is it rubs in the release position of a spring or latched held, which spring from the lever movable is. The lifting of the frictional or snap-fit held release position takes place in that the the spring out of holding effect lever the latch retracting lever is. This fulfills the case retracting lever a double function: on the one hand it serves to to bring the spring out of holding effect and on the other hand to withdraw the trap. It is possible the The described trap control mechanism is a normal one Assign mortise lock. It is also possible that the trap is one of a main lock drivable Additional lock is assigned. The additional lock even one can, by a separate drive rod possess operable latch. It is therefore a divided training of the drive rods before. The one is the lever and the other a pinion connecting slide assigned, which latter the bolt controls.

The espagnolette has an elongated, rail-like forend 1 with in the middle area of the same arranged main lock 2 and the same on both sides extending additional locks 3 same structure. The main lock 2 corresponds in its construction to the in DE 38 36 694 A1 described, so that only the for the invention essential details will be explained. The lockout of main lock 2 includes a main lock trap 4, the trap head 4 'a cross-section adapted Opening of the Stulpe 1 passes through. At the latch tail 4 '' accesses the case in the direction of exclusion acting latch spring 5 on. Of the Fallen tail 4 '' works together with one in the main lock 2 bearing pusher 6. The trap 4 is also displaceable by a change lever 7, in the lock housing is mounted pivotally about the standing pin 8. The change lever 7 is controlled by a lock in the longitudinal direction displaceable change slide 9. In one The open-width transverse slot 10 of the same engages a driving pin 11 of a segment disc 12 a below Leaving a clearance with the final wheel 13 of a Reduction gear U is in driving connection. The reduction gear U is driven by means of a closing member 14 of a in the main lock. 2 installable, not illustrated lock cylinder.

A firmly connected with the final wheel 13, smaller diameter Gear 15 meshes with a rack 16 one below the shuttle 9 in the main lock 2 guided Espagnolette fitting 17. The both ends of the same are coupled with espagnolettes 18. In the same plane to the first drive rod 18 extends there is a second, push nut operable drive rod 19, in such a way that both drive rods 18, 19 are opposite with their respective longitudinal edges and become the cross section of a normal complete wide drive rod. At the back are the drive rods 18, 19 of U-shaped cross-section Holding members 20.

To shift the change slide side drive rod 19 through the pusher 6 is one of the pusher nut radially extending wing 21, in its trajectory a shoulder 22 of the shuttle 9 protrudes.

The connected to the drive rod fitting 17 Drive rod 18 is coupled with an additional lock 3 in Stulplängsrichtung guided espagnolette slide 23. This has one at its upper end Control projection 24, which designed a hook latch Latch 25 controls. The main lock 2 has also a main lock bolt 26, however, of a gear of the reduction gear U forward and is closed back.

Below the hook-like bolt 25 of the additional lock 3, a trap 27 is guided in this. This sets in a known manner together from a case head 27 'and a latch tail 27' '. The case head 27 ' forms a trailing slope 28 which extends to the case head portion A is located, which in the first Trap position, cf. Fig. 3, the forend 1 surmounted. The trailing edge 28 is followed by a latch section B on. With this the trap enters its second Fallenvortrittsstellung in the Schließeingriffsöffnung 29 of a door frame-side striking plate 30 into it. To receive the bolt 25 is the strike plate 30 with a correspondingly positioned bolt entry opening 31 provided.

The tail-tail 27 'has one from its upper edge outgoing locking recess 32. This cooperates with an angle lever-like locking member 33. In his angle vertex the locking member 33 is a lock housing side Stehzen 34 stored, which in turn also for guiding the drive rod connection slide 23rd is used. At the towering, shorter Winkelarm 35 engages a tension spring 36, which the Locking member 33 loaded counterclockwise. Of the longer angle arm 37 of the locking member 33 forms on his free end a pawl head 38, which in turn, a control slope 39 and a shoulder 40 trains. The forend 1 facing control slope 39 extends obliquely to the direction of displacement of the Trap 27. In the first trapping position according to 3, the pawl head 38 protrudes into the catch recess 32 in and limited with the retaining shoulder 40th the trapping shift caused by the latch spring 41. The case 27 acts on it with a Counter Shoulder 42 Holding Shoulder 40. At his free End of the angle arm 37 is provided with an angled 43. The same forms on the forend 1 End face a detent recess 44, which with a locking projection 45 a lock box side mounted detent spring 46 interacts.

Furthermore, the latch tail 27 '' rearward with a driving shoulder 47 provided, which in turn with a stored at the lower end of the auxiliary lock 3 Fallenrückzug lever 48 cooperates. The same is pivotally mounted about a stay pin 49. used is the uprights 49 then still to guide the Espagnolette connector 23. There is an angle-shaped Design of the latch retracting lever 48 before. The free end 50 of the upward facing, the tail-tail 27 '' cross lever arm 51 forms a Nose and acts together with the locking projection 45th The downwardly obliquely downward lever arm 52 against it acts together with a bend 19 'of the drive rod 19, which in turn with the shuttle 9th is coupled.

The following mode of action occurs:

Is one with the inventively designed espagnolette If the door is closed, this will cause it the main latch 4 and the latch 27 of the additional lock 3 acted in Schloßeinwärtsrichtung. There the interaction of the main latch 4 is known is only on the operation of the case 27 of Additional lock received. In their relocation acts on the front, transversely to the case displacement direction extending wall 53 of the locking recess 32 the Control slope 39 of the locking member 33 and pivoted this against spring load in the upward direction. In the final phase of the upward displacement engages the locking projection 45 of the detent spring 46 in the detent recess 44 of the Locking member 33 and holds this in the release position to the case 27, cf. Fig. 6. Once the trap 27 with the Schließeingriffsöffnung 29 of the striking plate 30th Aligned, the tensioned latch spring 41 can be effective be and close the trap 27 in the position according to Fig. 7. By appropriate design of the not illustrated guide slot of auxiliary lock 3, the forward movement of the trap 27 is limited. It this is the second trap position, in which the locking portion B projects beyond the forend 1 and has entered the closing engagement opening 29, such that pushing back the latch 27, for example by means of a in the gap between strike plate 30 and Faceplate 1 inserted check card is prevented. It can now lock the espagnolette lock caused by key operation, wherein the main lock bolt 26 closes. Furthermore, will via the drive rod fitting 17 a downward movement the drive rod 18 causes, in turn, the Espagnolette connection slide 23 in the downward direction relocated. Their control projection 24 causes the hook-like latch 25 excludes and in the bolt entry opening 31 of the strike plate 30 retracts.

Opening the door first requires a key operation in the unlocking direction, wherein the latch 25, 26 are disengaged. With continuation of the Return operation, both drive rods 18, 19 slightly shifted in the upward direction. The relocation route the drive rod 19 serves to the latch retracting lever 48 to pivot. Its free end 50 raises the locking projection 45 from the detent recess 44th while, while the case 27 on the driving shoulder 47 at the latch tail 27 '' in lock inward direction is pulled, whereupon the position adjusts according to FIG. 9. If the lever action is canceled, so the trap 27 can move forward. There the locking member 33 is no longer through the projection 45th is secured, the pawl head 38 falls in the Lock recess 32 and secures the latch 27 in her first trap position.

With only drawn door without locking can a retraction of the latch 27 and cancel the detent position the locking member 33 achieved by press nut operation be with their wings 21 with the shoulder 22nd cooperates and the shuttle 9 in the upward direction moves and thus the drive rod 19, which in turn via the latch retraction lever 48, the retaining branch of the Locking member 33 lifts and on the driving shoulder 47 retracts the trap 27. After completion of the lever application can then trap 27 into its first Fall trapping position drive, what the pawl head 38 is limited. Coming with a pusher nut shift also the main lock latch 4 is withdrawn.

It is possible to show that at the additional lock Trap control mechanism in a similar manner to realize a mortise lock.

All disclosed features of this application are essential to the invention. In the disclosure of the application will hereby also the disclosure of the associated / attached Priority documents (copy of advance notification) fully involved, including for the purpose of Features of these documents in claims present To register.
