Abstract

The operating gear comprises a housing (2) with a operating slide or lever (7) that can be coupled with a drive rod (10) and is moveable in a first axial direction (L) about a predefined hub (H) through the rotation of a nut (3) mounted in the housing. There is a component that is a binding lever gear that facilitates drive restraint with the drive rod. There is, additionally, a further lever (5), with the nut and connected to the operating lever, that has a radial linkage (6) opposite the rotation axis of the nut. The operating lever has one end (7') that is linked, without means, to the lever. In the housing is a fixed locking mechanism that may be a cylinder lock, for instance. In the cylinder lock are control cams (25) located in a stop position in which locking of the lever gear and/or the drive rod, in a locked or unlocked position, can be changed. The control cams may be built with co-operating bolt (20, 20a) that has at least one locking catch (28, 29).

Description

The invention relates to an actuating gear, in particular lock, for a drive rod fitting according to the preamble of claim 1.

Also known are lifting and sliding doors for buildings, wherein the respective door wing such a door is lowered in the closed state to seals and locked against displacement and is raised to open, using a manually operable actuating gear, which is provided on the door and about an espagnolette fitting among others also cooperates with a lifting fitting on the door leaf. In the simplest case, the corresponding actuating gear then has two states, one of which corresponds to the lowered door leaf and the raised door leaf. But are also known lift-slide doors with additional tilt function, in which the door can be tilted in the lowered state, so that the actuating gear then has a total of three states.

An actuation gear is known ( DE 83 20 034 U1 ), which is particularly suitable for the espagnolette fitting a lift-slide door for buildings, including, inter alia, arranged in a housing of the actuating gear actuating slide or lever which is drivingly connected via a nose-like coupling portion with a drive rod of the espagnolette fitting and in a first , Its longitudinal axis enclosing axial direction is guided displaceably in the housing, and another, rotatably mounted in the housing and pivotable by a hand or lifting handle lever. This is drivingly connected via a rocker and two joints with the actuating lever, so that the actuating lever causes a displacement of the drive rod to a maximum stroke when pivoting the lifting handle between two end or extreme positions. The trained as a lever mechanism known actuating transmission comprises a total of three levers and two joints connecting these levers. The construction is not only consuming, but also requires a relatively large amount of space in the housing for the lever and its movement.

It is also known to integrate the Betätigungsgetriedbe in a castle ( DE 78 16 563 U1 ), which then has an actuatable via a lock cylinder lock, with which the actuating gear and / or a drivingly connected to this gear drive rod of the espagnolette in at least one state of the actuating gear is lockable. The disadvantage here is that this lock consists of a variety of items, with an increased design effort and with an increased space requirement in the interior of the housing of the actuating gear or the castle.

Finally, an actuating gear with the features of the preamble of claim 1 ( EP-A-0 367 843 ). For locking and releasing the movement of the drive rod, this known actuating gear on a single slidably mounted in the housing of the actuating gear latch which cooperates directly with a control cam of the Schfießzytinders and is movable by operating the lock cylinder in an axial direction between a locking and a non-locking position and locked in the locking position with locking lugs a drivingly connected to a drive rod driver slide.

The object of the invention is to develop a Betätigungsigtingsgetriebe, such as castle of the type mentioned so that while maintaining a flawless and safe function, the number of required functional elements is reduced.

To solve this problem, an actuating gear according to claim 1.

The actuating gear according to the invention or the driving rod fitting according to the invention are suitable for lifting-sliding doors, but also for lifting-sliding windows, in each case with or without tilt function. Despite simplified Construction, the actuating gear can be formed so that at least in an extreme or end position of a lifting handle or rotatably mounted in the housing and cooperating with the lifting handle nut by self-locking and / or by the lock cylinder actuated locking an undesirable displacement of the drive rod of the espagnolette and / or an undesired operation of the lifting handle of the relevant window or door is not possible.

For trained as a lifting gear operating gear only two levers are needed. As a lock is used in the corresponding embodiment of the actuating gear or lock according to the invention only a single bolt which is movable by pivoting about a bolt axis and by simultaneously moving radially to this bolt axis between a locking and non-locking position, preferably in that the relevant Lock cylinder or a control cam or driver of this lock cylinder interacts directly with the bolt or a control surface formed on this bolt.

"Nut" in the context of the present invention is generally a single or multi-functional element to understand, which is rotatably mounted in the housing of the actuating gear and drivingly connected via a gear with the manually operable lever handle and on which in the formation of the transmission as a lever gear eccentric is hinged on the hinge of the directly interacting with the drive rod actuating slide or lever.

That in the Figures 1-6 generally designated 1 lock is suitable for use on lifting and sliding doors and in the illustrated embodiment, especially for use in lifting and sliding doors with tilt function, in which the closed door can be tilted. The elongated lock 1 has a top 1 ', a bottom 1 ", a parallel to a longitudinal axis L of the lock 1 extending longer front side 1"' and also extending in the direction of the longitudinal axis L back 1 "".

The lock 1 consists essentially of a lock housing 2, which in the illustrated embodiment consists of two made of sheet steel by bending and punching boards 2 'and 2 "composed in the for Figures 1-6 selected representation on the upper side 1 'of the lock 1 and at the bottom 1 "of the lock 1 and also lying between them in a suitable manner and spaced from each other are connected and receive the essential functional elements of the lock 1. Between the housing 2 and its sinkers 2 'and 2 "are mirror-symmetrical to a center plane M formed parallel to the planes of the drawing Figures 1 - 4 and perpendicular to the plane of the FIG. 5 lies.

In the lock housing 2 or in the boards 2 'and 2 ", among other things, approximately in the middle of the housing 2, a nut 3 is rotatably supported, namely by an angular amount of about 180 ° about an axis perpendicular to the plane of the boards 2' and "or to the center plane M.

The nut 3 is provided with the usual square opening for the square of a rotary or lifting handle. Furthermore, the nut 3 has a fixedly connected to this nut and with respect to the axis of rotation radially projecting lever 5, on which by means of a hinge pin 6, the one end 7 'of a transmission or operating lever 7 is articulated. The axis of the hinge pin 6 is parallel to the axis of rotation of the nut 2 and thus again perpendicular to the median plane M.

The lock 1 is used together with an espagnolette fitting 8, the Stulpschine 9 is mounted in the manner known in the art in a groove of a fold of the relevant lifting rail door and essentially of a U-profile with the two legs 9 'and the In this curb rail profile, the drive rod 10 of the espagnolette fitting 8 is slidably received in the longitudinal direction of the profile for a given stroke H. The lever 7 serves to actuate this drive rod 10 made of sheet steel punched with one of its surface sides against the inner surface the yoke section 9 "rests and is guided with its longitudinal sides on the inner surfaces of the legs 9 '. About the drive rod 10, the fittings of the lift-slide door are operated in a known manner, including the closing elements and the elements for raising and lowering the door.

The made of flat material, for example made of sheet steel by punching lever 7 is at least in the two end or extreme positions of the nut 3 ( FIGS. 1 and 2 or 3 and 4) with its longitudinal extent parallel or approximately parallel to the longitudinal direction L of the housing 2 and guided in the direction of this longitudinal axis, which runs parallel to the faceplate 9 and the stroke H, slidably guided in the housing 2. For the actuation of the drive rod 10, the lever 7 engages with its other end 7 "or with a section 7" formed there as a driver in an opening 11 of the drive rod 10.

The lock 1 is taken with its lock housing 2 between the legs 9 'of the faceplate 9 and secured at the top and bottom at 12 and 13 by riveting on the legs 9'. The yoke portion 9 "facing side of the housing 2 forms the front side 1 "'of the lock 1. The driver 7"' protrudes so far beyond this front side 1 "that it extends into the immediate vicinity of the inner surface of the yoke section 9" and reliably engages in the opening 11 , With its the driver 7 '''facing away from and parallel to the longitudinal axis L extending back 7 "", the lever 7 is supported against a socket 14 in the interior of the lock housing 2.

As the figures further show, the lever 7 is executed in the region of its end 7 'angled, in such a way that in which in the FIGS. 1 and 2 shown state of the hinge pin 6 below the opening 4 and the axis of rotation of the nut 3 and in the second state of the Figures 3 and 4 is located above the axis of rotation of the nut 3, in such a way that the axis of the hinge pin 6 with the axis of rotation of the nut 3 lies in a common plane which includes the longitudinal axis L and parallel to the direction of movement or to the stroke H of the drive rod 10 is oriented. As a result, it is not possible in the two extreme positions of the nut 3, the (extreme positions) by cooperating with the lever 5 and by embossing from the material of the boards 2 'and 2 "generated stops 15 and 16, the drive rod 10 in impermissible Way to shift by force on this drive rod.

In order to guide the lever 7 also in the axial direction perpendicular to the median plane M, further stops or systems 17 are generated in the boards 2 'and 2, against which the lever 7 between its two ends 7' and 7 "with its surface sides is applied.

At the opposite outer surfaces of the boards 2 'and 2 "are provided with further generated by embossing stops or projections 18 which engage in mounted on the faceplate 9 lock 1 in recesses 19 in the legs 9' and thereby the lock 1 in addition to Secure the faceplate 9 against axial displacement ( FIG. 6 ).

In the lock housing 2, a bolt 20 is provided in the longitudinal direction L below the nut 3, which cooperates with a lock cylinder mounted in the lock 1, but not shown, to lock at least the drive rod 10 and release. Shown is the with its longer cross-sectional side parallel to the longitudinal axis L lying keyhole-like opening 21 for this lock cylinder.

The bolt 20 is pivotable about a bolt axis perpendicular to the median plane M and at the same time to limited strokes in axial directions parallel to the central axis M, that is held radially to the bolt axis displaceable in the lock housing 2, on a bearing bushing 22. The bolt 20 has for this purpose a bearing opening 23rd whose cross section is greater than the cross section of the bearing bush 22, which is located between the opening 21 for the lock cylinder, not shown, and the nut 3 or the axis of rotation of this nut 3. In the region of the bearing opening 23, a compression spring 24 is provided which acts between the bearing bush 22 and an abutment on the bolt 20 such that this spring 24 exerts a force on the bolt 20 radially to the bearing bush 22 and the bolt 20 in the non-locking state ( FIGS. 1 and 3 ) Pressed with the opening 21 and the lock cylinder, not shown edge region of the bearing opening 23 against the bearing bush 22 resiliently.

• An der der Öffnung 21 zugewandten Seite eine mit einem Steuernocken 25 des Schließzylinders unmittelbar zusammenwirkende Steuerfläche 26, die um Achsen senkrecht zur Mittelachse M bzw. parallel zur Achse der Lagerbuchse 22 konkav ausgebildet ist,
• eine an die Steuerfläche 26 in Richtung Schloßvorderseite 1"' anschließende Nase 27,
• eine über einen konkaven Umfangsabschnitt anschließende Sperrnase 28, die vom Riegel 20 in Richtung Treibstange 10 vorsteht,
• über einen konkaven Umfangsabschnitt auf die Sperrnase 28 folgend eine weitere Sperrnase 29, die über die der Steuerfläche 26 abgewandte Oberseite des Riegels 20 vorsteht und bei der dargestellten Ausführungsform mit ihrer Längserstreckung in etwa parallel zu der Achse 24' der Feder 24 liegt, und
• auf die Sperrnase 29 in der Richtung B folgend einen konvex gekrümmten, die Lageröffnung 23 ringförmig umschließenden Abschnitt 30, der dann schließlich in eine Nase 31 übergeht, die das der Nase 27 entfernt liegende andere Ende der Steuerfläche 26 bildet.

The bolt 20 has a peripheral contour, which is essentially determined by the following sections or elements and which connect in an assumed circumferential direction, for example in a clockwise direction (arrow B) to each other:

• On the side facing the opening 21 a directly cooperating with a control cam 25 of the lock cylinder control surface 26 which is formed around axes perpendicular to the central axis M and parallel to the axis of the bearing bush 22 concave,
• a nose 27 adjoining the control surface 26 in the direction of the front of the lock 1 "',
• a subsequent via a concave peripheral portion locking lug 28 which projects from the bolt 20 in the direction of drive rod 10,
• via a concave peripheral portion of the locking lug 28 following another locking lug 29 which projects beyond the control surface 26 facing away from the upper side of the bolt 20 and in the illustrated embodiment with its longitudinal extent approximately parallel to the axis 24 'of the spring 24, and
• on the locking lug 29 in the direction B following a convex curved, the bearing opening 23 annularly enclosing portion 30, which then finally merges into a nose 31, which forms the nose 27 remote from the other end of the control surface 26.

On the front side 1 "', a support and sliding guide 32 is formed on the lock housing 2 by angled lobes of the boards 2' and 2" on which the locking lug 29 slides with its side facing the front side 1 "'. 'turn formed by angled lugs of the boards 2' and 2 "a catch 33 which cooperates with the nose 27 of the bolt 20 in the manner described in more detail below.

By imprints 34 and 35 in the boards 2 'and 2 "2 protruding guides or projections for the latch 20 are formed in the interior of the lock housing, which prevent misalignments of this bolt.

The function of the lock 1 can be described as follows:
The FIG. 1 shows the lock 1 in a first state in which the drive rod 10 is in the lower position of its stroke H and corresponds to the lowered state of a lift-slide door. The hinge pin 6 is in this state below the axis of rotation of the nut 3, in such a way that the axis of the hinge pin 6 and the pivot axis of the nut 3 are arranged in a common, the longitudinal axis L enclosing plane. The latch 20 is in a position in which neither the drive rod 10, nor the nut 3 are locked by this latch.

From the in the FIG. 1 reproduced non-locking position of the latch 20 in both the nut 3 and the drive rod 10 locking position of figure 2 The bolt 20 is thereby raised against the action of the spring 24 in the direction of the nut 3 and away from the lock cylinder radially to the bearing bush 22, at the same time in the direction of the Arrow B pivoted about the axis of the bearing bush 22 and also in an axial direction perpendicular to the longitudinal axis L radially to the bearing bush 22 slightly to the front 1 '' out, so that the locking lug 28 engages in a locking opening 36 of the drive rod 10 and thus the drive rod 10 against The locking lug 29 is in this case arranged between the guide 34 and the end of the lever 5 and thus prevents the pivoting of the nut 3 from the in the FIG. 2 shown location. The nose 27 is based on the rest 33. The tensioned spring 24 generates a torque about a bearing formed by the free end of the nose 27 and the latch 33 bearing in the direction of arrow B, so that is secured by the tensioned spring 24 of the bolt 20 in the locking position.

As the FIG. 2 shows, continues the axis 24 'of the spring 24 in this locking position of the bolt 20 no longer radially to the axis of the bearing bush 22, but tangent to an imaginary circular line about the axis of the bearing bush 22, in such a way that the axis of the bearing bush 22nd and the abutting against the detent 33 nose 27 are provided on different sides of the axis of the spring 24, which results in securing the locking position of the bolt 20 is another Übertotpunktwirkung that must be overcome upon return of the bolt 20 in the non-locking position.

The return of the bolt 20 in the non-locking position is again by corresponding actuation of the lock cylinder via the control cam 25, which then cooperates with the nose 31 formed on the part of the control surface 26, in such a way that the nose 27 against the Übertotpunktwirkung of the spring 24 withdrawn from the catch 33 and the latch 20 is pivoted back into its non-locking position.

The FIGS. 1 and 3 make it clear that in this non-locking position of the bolt 20, the axis 24 'of the compression spring 24 is not only radially to the axis of the bearing bush 22, but on this axis 24' at least approximately that point is located at which the bolt 20 in the region Bearing opening 23 abuts against the bearing bush 22 and that further by the shape of the bearing bush 22, the spring 24 has its greatest relaxation. The spring 24 thus generates virtually no torque on the bolt 20, so that it is in a stable, non-locking position.

In non-locking latch 20 can be moved by turning or pivoting the nut 3 via the levers 5 and 7, the drive rod 10 in its upper stroke position, for example, in a lift-slide door without tilting the raised position of the door and a lifting Sliding door with tilt function corresponds to the tilted position of the lowered door. In this upper stroke position of the drive rod 10, the hinge pin 6 is above the pivot axis of the nut 3, wherein the pivot axis of the nut 3 and the axis of the hinge pin 6 are in turn arranged in a plane which includes the longitudinal axis L, so that the drive rod 10 alone already secured by this arrangement of the hinge pin 6 relative to the axis of rotation of the nut 3 via the lever 7 against unauthorized pushing back from the upper stroke position.

To lock the drive rod 10 can also in this second state of the lock 1, the bolt 20 by corresponding actuation of the lock cylinder in the in the FIG. 4 shown locking state, which differs from the state of FIG. 2 only differs in that the locking lug 28 engages not in the locking opening 36, but in a further, provided on the drive rod 10 locking opening 37.

At the bottom 1 "of the lock 1 and the lock housing 2 is still a nose 38 is provided in the well-known manner, one end of a spring, not shown, can be mounted, which engages with its other end to the drive rod 10 and this in the stroke direction H biasing upward to a To achieve the lowest possible lowering of the drive rod 10 and thus the respective door and to avoid at least unpleasant for the operator hitting the connected to the nut 3 lever handle when lowering the door.

The FIG. 7 shows in a simplified representation as a further possible embodiment of a lock 1a, which differs from the lock 1 essentially only in that the local latch 20a, which corresponds in terms of its function and training the latch 20, on at least one of a board 2a 'of the housing 2a facing side on the nose 31 and at the transition of the nose 31 to the rest of the bolt 20 has a guide projection or pin 39 which 'engages in a recess 40 of the board 2a and there formed by the action of the spring 24 against a backdrop guide and the axis of the bearing bush 22 remote edge region 41 abuts. The edge region 41 has on both sides of a protruding into the recess 40 portion 41 'each have a portion 41 "or 41"', which is formed by a trough-like widening of the opening 40 and of which the portion 41 "the guide projection 39 in the non-locking state of the bolt 20a and the portion 41 "'receives the guide projection 39 in the locking state of the bolt 20a.

The invention has been described above by means of exemplary embodiments. It is understood that changes and modifications are possible without thereby departing from the inventive concept underlying the invention. Thus, for example, it is possible to provide on the nut 3 ring-like sliding parts of a suitable, low-friction material, such as plastic where the nut 3 in the boards 2 'and 2 "is rotatably mounted.

Actuating gear according to one of the preceding claims characterised in that the bolt (20, 20a) is mounted with a bearing opening (23) on a bearing bush (22), and that the bearing opening (23) has in order to achieve the additional movement of the bolt (20, 20a) in the at least one further axial direction , a cross-section which is greater than the cross-section of the bearing bush.
16. Actuating gear according to one of the preceding claims characterised in that the spring means are provided in the area of the bearing opening (23) and act between the bearing bush (22) and a counter bearing for the spring means (24) which is provided on the bearing opening (23).
17. Actuating gear according to one of the preceding claims characterised in that the bolt (20a) has at least one guide pin (39) which is moulded on and interacts with a sliding guide (41) on the housing (2).
18. Actuating gear according to one of the preceding claims characterised in that the housing (2) is formed mirror symmetrical to a centre plane (M) which runs perpendicular to the rotational axis of the follower (3) and/or that the housing (2) is housed between arms (9') of a profiled casement track of the drive rod fitment (8) and a casement track (9) of this fitment respectively.
19. Actuating gear according to one of the preceding claims characterised by projections (18) as well as by recesses (19) on the housing (2) interacting with these or on the casement track (9) for the precision positioning of the housing (2) relative to the casement track.
20. Drive rod fitment with at least one drive rod (10) and with an actuating gear for the drive rod (10) according to one of the preceding claims.
