Abstract

The lock assembly has a spring bolt and a multi-part follower. A divided push pin (12') is inserted into the center section of the follower for a selective operation of the spring bolt retraction either from one or the other pressure sides. The operating side is selected through the insertion depth of the push pin in the follower. The follower has at least three sections (14-17) in succession, where only a center section (17) engages the spring bolt.

Description

The invention relates to a lock, in particular espagnolette lock with a trap and a multi-part Nut for inserting one divided in the middle part of the nut Printer mandrel for optional actuation of the latch retraction either only from one or only from that the other side of the handle, with a latch retraction also should be possible from both sides.

Such a lock is from the European patent application EP 0 712 987 A2. There is the printer nut divided into two. The two nut parts are in the handle axis direction axially one behind the other and take each a pusher mandrel section one split in the middle Trigger pin. Each of the two nut halves has one arm, optionally with a stop of the trap tail can cooperate to withdraw the trap. Such an arrangement allows, for example, that A door handle is provided on both sides of an apartment entrance door is. A trap withdrawal is only possible with the inner trigger possible.

The invention has for its object a generic Advantageously to further develop the lock.

The task is solved by the in the claims specified invention.

The solution specified in claim 1 aims to that the actuation side by the insertion depth of the associated section of a two-part mandrel is selectable in the nut. As a result of this configuration are no complicated changes at the castle necessary. The setting in which of the two press pins is to enable the trap retreat made the choice of the length with which the respective Lever pin protrudes into the follower nut. Constructive this is advantageously achieved in that axial center area of the nut a latch retraction part lies with the end portion of the respective pusher portion can be coupled. The division level of the two-part Pusher mandrel is then outside this axial Center area. An advantageous embodiment provides that the nut is at least three in the direction of the handle axis forms successive nut sections. The middle section of the nut is supposed to be the trap retraction part form. The two outer nut parts can Train holding parts with which the trigger pin in Lock is held. These holding parts can be made accordingly be a cross-sectional profile of the handle mandrel profile and let yourself be turned by the pusher. In advantageous Way, these two outer holding parts are at least in cushioned in one direction of the trigger actuation. Prefers is that these holding parts according to a bilateral Suspension in a middle neutral position being held. The middle nut section is preferred provided with a driver on an actuating arm a change lever arrangement acts. This Change lever arrangement works again with the operating arm to a stop sitting on the trap tail. In advantageously the actuating arm is the same Axis rotatable, like the latch retraction part of the nut. The two outer nut sections, which form holding parts are preferably with a cam clutch a middle nut part coupled, which the drive rod either in a direction of closure or in a Can take opening direction. The drive rod entrainment takes place from a middle neutral position of the trigger either in one or in the other direction. For this purpose, the drive rod displacement member the nut with the outer nut parts over one Access coupled. The trigger is then from a sprung neutral position in two directions pivotable, the pivoting movement in one direction the drive rod in an open position and the Swiveling movement in the other direction the drive rod shifted to a closed position. The one from the nut trained latch retractor is with the handle coupled via an access, which in particular in the Espagnolette opening position an access of the outer Nut part allowed. The outer nut parts preferably have a design of the push-through hole, which corresponds to the handle cross-section, so that this Holding parts can also be turned during a handle rotation. The latch retraction part also has a pusher profile. In principle, this can also correspond to the cross section of the handle profile, so that the latch retraction part is taken away by the handle. However, an embodiment is preferred in which the Lever with an approximately 45 ° clearance in the lever profile can be rotated. To do this the handle-entraining profile protrudes radially inwards Projections against the polygon of the square profile of the trigger. It is also envisaged that the pusher take profiling of the latch retraction part due to axial clearances of neighboring lever-driving profiles the outer nut sections spaced is. In the space of these axial clearances then the point of separation between the two butts Pusher sections. Another Design provides that these axial clearances Form circular cross-sectional contours. The one from the Arms formed on the two outer nut parts are on both sides cushioned. One-sided only needs one Spring package to be provided, each of which is opposite spring packs both arms at the same time cushioned. The two outer nut sections can by means of one each engaging in annular groove sections Rib of the drive rod actuating part are guided. The actuator stem has an opening through which the trigger pin can protrude. Has this opening also a circular cross section.

The trap can be moved longitudinally on the cuff arranged gate valve in the retracted Be held. On the cuff is also a sensing element is provided which forms a locking lug, which locks the drive rod in the open position.

The lock of the embodiment has a main lock 1, which fastens a cuff 5 on the back is and has a trap 2, the means in a nut 3 inserted pusher 38 is retractable. Further the lock has a locking cylinder 4 by means of which a latch is lockable when the drive rod 6, which is guided behind the cuff 5 in a Locked position is shifted. In the open position the latch 8 is not lockable. The drive rod 6 connects a connecting rod connecting slide in the main lock 32 with secondary locks 7, from which in Push out the espagnolette locking position.

The main lock has a trap 2. To the head of the Trap 2 is followed by a trap tail 25 that opens its back forms a stop 24, which of a screw pin is formed, which can be screwed over is so that the trap head is reversible. On the back the trap 2 is cushioned by a trap spring.

The latch can be activated by actuating the locking cylinder 4 withdrawn, for which purpose a change lever 30 on one around the center of the nut 3 mounted lever 23 acts which forms an actuating arm 19 which against the stop 24 acts.

On the back of the lock case are in Opposite two spring assemblies, each made up of a compression spring 28, 29, which compared to the Housing are cushioned. On the other side of the Compression spring 28, 29 is an actuating slide 26, 27, which can only be shifted against spring force. Find between the two operating slides 26, 27 Arms 21, 22 of nut parts 14, 15 receptacle. Should they Nut parts 14, 15 are rotated, this can only against one of the two springs 28, 29 is loaded. The two sprung arms 21, 22 are opaque and touching each other.

The nut parts 14, which can also be referred to as holding parts, 15 are on the one hand in openings in the housing cover or of the housing bottom rotated and form the outer Parts of the nut consisting of several parts 3 out. The holding parts 14, 15 have an opening with a rectangular cross-sectional profile. This rectangular one Cross-sectional profile corresponds to the cross-sectional profile of the trigger mandrel 12, 12 ', 12' '. The two nut parts 14, 15 form fork-shaped slots, which are counter-stops 42, 43 for the nut part 15 and 44, 45 for Nut part 14 are limited. Between the counterstops 42, 43 and 44, 45 are driving projections 40, 41 a middle nut part 16, which as a drive rod confirmation part referred to as. The actuator stem 16 forms an arm, which ends forms a drive rod driver 20. The actuator stem 16 also forms the said Take-out projections 40, 41 from opposite ones Project pages in the axial direction of the handle and between said counterblows 42, 43 and 45, respectively come to rest.

The drive rod driver 20 engages in a transverse slot recess of the connecting rod connecting slide to the connecting rod slide 32 when pivoting of the drive rod actuating part 16 either in the Open position upwards or in the locked position or closed position to take down.

The drive rod actuating part 16 is over the counter stops 42, 43 entrained by the nut part 15, if that Nut part 15 has been pivoted by means of the handle. The drive rod actuating part 16 can also from the nut part 14 can be taken if the associated Carriage projection 41 from one of the counter stops 44 or 45 is applied.

The drive rod actuation part 16 is carried along starting from a middle neutral position by pivoting the push button 28 either in the direction shown in Fig. 4 or in Fig. 3. If the drive rod actuation part 16, for example, in a dragged open position shown in Fig. 3, so the pusher 38 can be spring loaded by the spring 29 on one of the arms 21 or 22 in the spring back neutral center position without the Driving rod actuating part 16 pivots back. This is a consequence of the clearances between the counterstops 42, 43 or 44, 45. In an analogous manner, the Espagnolette operating part 16 by pivoting the Pusher 38 in the opposite direction (see FIG. 4) in one Lock position to be shifted. After releasing the Pusher 38 springs the pusher into the neutral central position according to the action of the spring 28 back without the connecting rod or the connecting rod actuating part 16 to be carried.

In the espagnolette locking position, as shown in FIG. 4 is shown, the bolt 8 by pressing the Lock cylinder are pre-locked, the Lock bit lock cylinder lifts a tumbler 34. In the open position shown in FIG The additional bolts are locked to the connecting rods. In this position the bolt 8 cannot be pre-locked because the wall sections run out at an angle the bolt passage opening in the drive rod into a Lock groove 35 of the bolt have occurred, and so the Prevent latch from being locked by positive engagement.

From what has been said it follows that the connecting rod both from an outside handle and from an inside handle both in the reverse direction and in the opening direction is relocatable, the respective operated Push button 38 back to the neutral middle position can be. On the one hand, this is possible if the pusher, as shown in Fig. 14, as a one-piece Pusher mandrel 12 is formed. It is also possible if the pusher, as in Figures 12 and 13 is shown, has a trigger mandrel, which is divided into two and two pusher mandrel sections 12 'and 12' ' forms the blunt about in the middle of the nut at the point of separation 13 collide.

The drive rod actuation part 16 has ring-section-shaped Ribs 48, 49 on both sides in the axial direction protrude and slide in grooves 47 or 46 are guided, the annular groove portions 46, 47 each the holding parts 14, 15 are assigned so that these nut parts 14, 15 via the drive rod actuating part 16 are connected.

The latch retraction, which occurs when the handle 38 is relocated in the position shown in FIG. 10, is caused by a special nut part 17, which is located between the nut parts 14, 15. This Nut part 17 is referred to as the trap retraction part. The Latch retraction part 17 forms a driver 18, against a stop edge of the actuating arm 19 bumps. The latch retraction part 17 forms an opening through which the trigger pin 12, 12 ', 12' 'can be inserted is. This opening has a pusher profile, so that the handle rotation to a Transfer pivoting movement of the latch retraction part 17 becomes.

The pusher profile is in the embodiment but not exactly the square handle profile adapted, but forms radially into the opening protruding projections 39. These projections 39 are arranged so that the pusher is inside the Lever push-through opening of the latch retraction part 17 around can freely rotate an angle of approximately 45 °.

In the axial direction are next to the pusher profile axially extending free spaces 36, 37. These free spaces 36, 37 are formed on the one hand from a recess 36 of the nut part 14 and on the other hand from a circular handle opening of the drive rod actuating part 16, which between Trap retraction part 17 and holding part 15 is located.

The separation point 13 of the butt and Pusher mandrel sections that are not entrained in rotation 12 ', 12' 'is either in the free space 36 or in the Free space 37. Correspondingly, one is 12 'or another 12 '' handle mandrel section rotatably coupled with the latch retraction part 17. An actuation of the other Pusher mandrel section causes displacement of the drive rod but no trap retreat. By change the insertion depth of the mandrel sections 12 'or 12 '' the separation point 13 can be moved from one in the position shown in Fig. 12, where in the free space 37 lies in a position shown in FIG. 13, where the separation point 13 lies in your free space 36. In the position shown in Fig. 12 can the latch is retracted with the trigger mandrel 12 '. A pivoting of the trigger mandrel 12 ″ does not effect any Trap retreat. The one shown in Fig. 13 The latch can be set by turning the trigger pin 12 '' can be withdrawn. A rotation of the trigger pin 12 'causes no trap retraction.

The presser pins 12 ', 12' 'can be different Have length.

There is a locking slide on the front of the cuff 10, the one with a retracted trap Gate valve section in front of the front edge of the trap can be pushed so that the trap in the retracted Position must remain. At the gate valve section it is a corner section.

A pushbutton 11 protrudes from the faceplate 5, which on its back forms a nose 31, which in a transverse slot of the connecting rod connecting slide 32 can snap to a displacement of the connecting rod connecting slide 32 to prevent. For this is the feeler 11 by means of a spring 33 in the face-to-face direction cushioned. The displacement of the probe 11 against the spring 33 is made by impact on the door frame.

The lock works as follows:

Starting from the neutral position shown in Fig. 7, in which the drive rods are in an open position, stand up, both in the representations front inside handle, as well as the in the representations of the rear outside handle either shift left or right. In the shown in Fig. 7 The two nut parts 14, 15 of the sliders 26, 27 which are sprung onto the two Arms 21, 22 act in a middle sprung Position held. The driver 18 is in the system to the arm 19. The edges of the rectangular recess of the Nut parts 14, 15 lie approximately in the middle of the the projections 39 left free spaces of the handle take profile the trap retraction part 17, so that the Push slightly into both one and the other position can be shifted without the trap retreat part 17 relocated.

Both the trigger mandrel section 12 'and the other pusher mandrel sections 12 '' can be obtained from the 7 shown neutral position as shown clockwise up to bring about the locking of the drive rods. To Handle actuation takes the lock that shown in Fig. 8 Function position on. The rotation of the handle dome 12 '' causes the nut part to pivot 15. The counter stop 43 acts on the driving projection 41, so that the drive rod actuating part 16 pivoted and the drive rod down into the Lock position takes. The arm 21 compresses the spring 28.

If the trigger mandrel 12 'is released, it causes Spring 28 a return rotation of the nut part 15 in the sprung Neutral position. The castle then takes in Fig. 9 position shown, with the edges now the handle 12 '' no longer freely in the free spaces the pusher profile of the latch retraction part 17 protrude, but are in contact at the edge to the projections 39.

If the handle from the position shown in Fig. 7 shifted clockwise, so the closing hangs. function entirely depending on which of the two trigger mandrel sections 12 'or 12' 'is actuated. In the case of Fig. 12 pusher mandrel position shown causes a pivoting the trigger mandrel section 12 'that in FIG. 10 shown closed position. The trigger mandrel 12 'takes the latch retraction lever 17 with, so that the trap retracted becomes. Is actuated with the trigger mandrel section 12 '', the lock takes the one in Fig. 3 position shown. The trap retreat part 17 is now not dragged along by the pusher section 12 '', but only the drive rod actuation part 16.

All the features disclosed are essential to the invention. In the disclosure of the application is hereby also the Disclosure content of the associated / attached priority documents (Copy of the pre-registration) in full included, also for the purpose, characteristics of this Documents in claims of the present registration with to record.
