Description

The invention relates to an espagnolette for inactive leaf of double-leaf windows or doors without mullion, with an operating lever and thus pivotally connected to a coupling point toggle lever, wherein an end portion of the operating lever or the toggle lever is pivotally mounted on a stationary bearing and the end of the other lever is coupled at a coupling point with a drive rod and causes a pivoting movement of the operating lever from a locking position into an unlocking position, a displacement of the drive rod.

Such a drive rod fitting is for example from the EP 1 790 805 B1 known. Double-leaf windows or doors without center posts, also referred to as non-sessile windows or doors, have a fixed leaf and a moving leaf. The active leaf can be rotatable and / or tiltable openable. The fixed wing is usually only drehöffenbar. As a rule, an operating lever is arranged in the rebate area between the inactive leaf and the active leaf on the inactive leaf, with which the inactive leaf can be unlocked. Frequently, the operating lever is pivotable in a plane perpendicular to the wing plane. An espagnolette fitting with a pivotable perpendicular to the wing plane control lever is for example from the DE 8711496 U1 known.

However, embodiments are also known in which the operating lever is pivotable in a plane parallel to the plane of the wing. If the inactive leaf is unlocked, the operating lever usually stands out from the inactive leaf. This can cause damage to the control lever and the mechanism driven by it. Also, the operating lever poses a certain risk of injury when it protrudes from the wing.

From the DE 202 13 937 U1 an espagnolette fitting is known in which a control lever is pivotally mounted with one end on a faceplate. A toggle is both pivotally connected to the operating lever and with a drive rod. All coupling points of this espagnolette fitting are unsolvable. In a movement of the operating lever is always a movement of the drive rod.

From the EP 1 335 089 A1 An espagnolette is known in which a control lever is pivotally mounted in a stationary bearing. A toggle pivotally connected to the control lever is fixedly coupled to the drive rod. At the axis of rotation of the lever, a gear is provided which meshes with serrations of two tangentially extending tooth engagement of two drive rods. This means that the drive rod is formed in two parts and the Move the espagnolette parts in different directions when operating the control lever.

The EP 1 050 647 A1 discloses a drive rod fitting in which the operating lever can be pivoted beyond the unlocked position, so that the lever does not protrude into the traffic space when the espagnolette is open when it is forgotten to close the closure.

The EP 1 790 805 B1 discloses a lever mechanism for a cuff rail and a longitudinally movable drive rod having espagnolette for passive leaf of double-leaf windows or doors without mullion, wherein a control lever by means of a cuff rail associated and perpendicular to the longitudinal axis extending stationary axis of rotation is pivotal and drives the drive rod by means of a connecting lever which is rotatably connected to a first bearing with the operating lever and a second bearing with the drive rod. A connection between the operating lever and the faceplate on the stationary axis of rotation or between the connecting lever and the drive rod on the second bearing is decoupled, so that the operating lever is not in drive connection with the drive rod and this decoupled connection can be produced by operating the operating lever, so that the control lever is drivingly connected to the drive rod. The decoupling can be accomplished only with a considerable effort. Normally, a decoupling is not provided. In particular, the decoupled state only serves to ensure that the lever during storage and assembly, so when the fitting is fixed in its rotational opening position, is applied to the fitting and thus for a not in the way and to other less storage space claimed. A decoupling during operation is not provided.

Object of the present invention is to propose an espagnolette fitting, in which a Hineinragen the operating lever can be reliably avoided in the traffic area with unlocked passive leaf.

This object is achieved according to the invention by an espagnolette for passive leaf of double-leaf windows or doors without mullion, with an operating lever and thus pivotally connected to a coupling point toggle lever, wherein an end portion of the Bedienhebeis or the toggle lever is pivotally mounted on a stationary bearing and the end of the each other lever is coupled to a coupling point with a drive rod and a pivoting movement of the operating lever from a locking position into an unlocking position causes a displacement of the drive rod, wherein one of the coupling points in the unlocked position of the operating lever is automatically releasable, such that upon pivotal movement of the operating lever the unlocking in its locking position corresponding initial position no displacement of the drive rod is in its locked position. This means that the operating lever, after it has been pivoted to unlock the passive leaf, can be pivoted back into its initial position without locking elements which are arranged on the drive rod, are adjusted. In particular, a closed passive leaf is not locked. The inactive leaf can therefore continue to be opened. However, the operating lever is not in the traffic area. The operating lever therefore executes an idle stroke.

The fixed bearing is in particular stationary with respect to a faceplate, which may be provided on the espagnolette fitting. The pivot axis of the stationary bearing can be arranged above or below the drive rod, in particular on the faceplate side facing, ie between the drive rod and face plate, or the faceplate side facing away from the drive rod. However, the pivot axis can also be arranged on the side facing away from the drive rod of the faceplate. Preferably, the espagnolette fitting is not safe to operate. The incorrect operation safety is thereby ensured or means in this context that the fitting can not (inadvertently) be brought into the closed position when the inactive leaf is open, since the control lever is decoupled and its renewed operation has no effect. Thus, the closing of the inactive leaf is possible and locking takes place only in the closed position by the interaction with the active leaf.

One of the coupling point is inventively in the unlocked position of the operating lever automatically released. This means that the coupling is canceled at a coupling point as soon as the operating lever is in its fully pivoted unlocking position. For example, the espagnolette fitting can be designed so that a pivoting movement of the operating lever leads upwards to an unlocking. After reaching the unlocked position, an automatic uncoupling takes place, so that the operating lever is returned to its locking position (initial position) solely on the basis of gravity, but without the drive rod also getting into the locking position. If, however, the espagnolette fitting is used so that a pivoting movement down to an unlocking and displacement of the drive rod leads, so for example spring elements can be provided be that reset the operating lever to its original position. Since an automatic decoupling takes place before, the return of the operating lever does not also lead to a displacement of the drive rod. Thus, the operating lever can assume its initial position or applied position even with drehgesoffenem passive leaf, without that also the espagnolette fitting, in particular the drive rod of the espagnolette, occupies the locking position.

According to an advantageous embodiment of the invention coupled to the drive rod, in particular attached thereto, return means may be provided which allow a displacement of the drive rod in a locking position regardless of an operation of the operating lever. Since the operating lever arrives due to the decoupling in its initial position, without the drive rod is shifted back, return means must be provided which allow an independent control lever displacement of the drive rod in a locking position. For example, a manually operable driver can be provided on the drive rod, so that the drive rod can be moved manually into a locking position. Furthermore, it is conceivable to provide a driver on the drive rod, which is actuated by fitting parts of the active leaf, so that a locking of the passive leaf occurs when the active leaf is closed or locked. In particular, if it is provided that the inactive leaf is locked by fitting parts of the active leaf, it is ensured that the espagnolette fitting is misused, so that in any case a locking of the inactive leaf takes place when the window or door is completely closed and the active leaf is locked.

At the leaf, the drive rod moves to lock usually upwards. The locking of the inactive leaf via a driver provided on the driving rod therefore requires that the driven driving rod section in the moving leaf can also be moved upwards for locking. However, this is not possible in the lower region of the inactive leaf (or only with a further complicated stroke reversal), if there the usual direction of movement, i. a displacement of the drive rod down, to be maintained, in particular, e.g. a rod ejection is done for locking. In this case, the driver would have to lie in the upper half of the espagnolette fitting. About a stroke reversal, i. a two-piece drive rod can be made, that in the lower part of the drive rod is moved down.

Advantageously, the operating lever or the toggle lever can be coupled via a driver with the drive rod. The driver can engage a drive rod to move it from a locking position to an unlocked position. On the other hand, the driver may be movable relative to the drive rod, so that after a decoupling of the driver can be moved back to its original position without the drive rod is moved simultaneously.

The driver may be pivotally connected to the operating lever or toggle lever and limited to be movable relative to the drive rod. For example, the driver may have a driving pin, which is arranged in a slot of the drive rod. To have, which is arranged in a slot of the drive rod. To unlock the drive rod, the driver can attack at one end of the slot and thereby displace the drive rod in a movement that was caused by the operating lever. In a provision of the operating lever, the driving pin can move in the slot of the drive rod, so that no displacement of the Drive rod takes place when the operating lever is moved back to its initial position, When the driver moves relative to the drive rod, the coupling point is decoupled,

Components can be saved if the driver is not formed as a separate part, which is pivotally mounted on the operating lever or toggle, but when the driver is formed on the operating lever or toggle lever.

It when the detachable coupling position is manually coupled, such that a pivoting movement of the operating lever from a release position into a locking position causes a pre-storage of the drive rod in a locking position is particularly advantageous. This means that normally a decoupling occurs automatically when the operating lever is in the unlocked position. However, if a lock is to be done by means of the operating lever, the coupling can be made manually by a user, so that is coupled with a return movement of the operating lever in its locking position of the operating lever to the drive rod and causes a displacement of the drive rod in the locked position. This has the advantage that the inactive leaf can also be easily locked without the need for fitting parts of the active leaf. It is understood that the possibility of locking by the active leaf or fitting parts of the active leaf can additionally exist.

It when the operating lever or toggle has a cooperating in the locking direction with a stop of the drive rod stop is particularly advantageous. About this stop, the operating lever or the toggle lever can be manually coupled to the drive rod, so that upon a return movement of the operating lever in his Locking position also occurs a displacement of the drive rod in a locking position. It makes sense, the drive rod has a corresponding stop, which cooperates with the stop of the toggle lever or operating lever. For example, the drive rod may have a recess and may serve as part of the boundary of the recess as a stop for the stop of the operating lever or toggle lever.

According to one embodiment of the invention can be provided that the free end of the operating lever or the toggle lever is hook-shaped, wherein on the side facing away from the hook tip a cooperating with the drive rod stop is provided. To displace the drive rod from a locking position into an unlocked position, the hook of the operating lever or the toggle lever can engage a corresponding stop of the drive rod or engage in an opening in the drive rod. Due to the curved shape of the hook-shaped end of the operating lever or the toggle lever, the operating lever or the toggle lever automatically comes with a movement of the operating lever from an unlocked position into the locking position out of engagement with the drive rod. However, the operating lever or the toggle lever can be brought manually with the hook tip opposite stop in abutment against a stop of the drive rod, so that even with a movement of the operating lever in a locking position, a displacement of the drive rod is done and a locking of the passive leaf. Due to the configuration of the operating lever or the toggle lever with a hook-shaped end, which can be regarded as a driver, and a stop no other components are necessary to establish the coupling between the operating lever or toggle lever and the drive rod. Further advantages arise when a bearing block is provided for stationary mounting of the operating lever or the toggle lever. Through this bracket can support the espagnolette down, so done on the groove bottom of a fitting part of the inactive leaf. Furthermore, the bearing block can represent a driving rod guide. In particular, the bearing block can pass through the drive rod, so that the drive rod is guided on the bearing block. The bearing block can be made of plastic or zinc die-cast part. Furthermore, the bearing block can represent a screw guide, so that the espagnolette fitting can be fixed on the bearing block on the inactive leaf. The faceplate can also be connected to the bearing block.

In particular, when the espagnolette fitting is to be used so that a pivoting movement of the operating lever down to unlock the espagnolette, it is advantageous if a spring element is provided, and the operating lever is pivotable against the restoring force of the spring element from the locking position to the unlocked position , Thus, an automatic reset of the operating lever from the unlocking position to the locking position. The spring element can also be installed so that it additionally leads to an automatic decoupling results at a coupling point when the operating lever is in an unlocked position. In particular, this can be ensured that the hook-shaped end of the operating lever or the toggle lever out of engagement with the drive rod and the stop, which is opposite the hook-shaped end, does not cooperate in the locking direction with a stop of the drive rod.

According to one embodiment, it can be provided that the drive rod has at least two oppositely movable drive rod sections. This makes it possible to produce a locking of the passive leaf by rod exclusion, so that the drive rod sections engage above and below in corresponding recesses of the window or door frame or engage behind the locking pieces. In general, however, locking elements will be arranged on the drive rod or drive rod sections, which cooperate with corresponding closing pieces which are arranged on the fixed frame. The locking elements can be distributed over the circumference of the inactive leaf and driving rod sections can be coupled in motion via Eckumlenkungen.

The invention also includes an espagnolette fitting arrangement with an espagnolette fitting according to the invention associated with a stationary leaf and an espagnolette fitting comprising a locking means which, when the active leaf is closed or when the active leaf is locked, is connected to return means of the espagnolette associated with the stationary leaf for displacing the drive rod, or an espagnolette section, of the stationary leaf associated espagnolette fitting cooperate in a locking position. As a result, the espagnolette fitting of the inactive leaf can be driven via fitting parts of the espagnolette fitting of the active leaf for locking the inactive leaf.

The locking means may comprise a locking element, a driver or a wing lifter, which cooperate with a, in particular designed as a driver, return means of the espagnolette fitting. For example, drivers on the drive rod the espagnolette of the passive leaf be arranged so that you are unlocked but closed inactive leaf above a locking element or driver of the active leaf, so that they are at a locking of the active leaf by the locking elements or the driver of the active leaf, which are moved to lock up , also be taken upstairs. As a result, there is also a displacement of the drive rod of the espagnolette of the inactive leaf, so that the inactive leaf is locked.

Alternatively, it can be provided that a Niveauschaltsperre the espagnolette of the active leaf when closing the active leaf runs on a corresponding driver on the drive rod of the espagnolette of the inactive leaf and displaces the driver of the espagnolette of the inactive leaf further down the active leaf, which also causes a shift of Drive rod downwards, so that the inactive leaf is locked. To ensure this function, the wing lifter, in particular a lever thereof or a comparable component, an extension, for example, a fork-shaped extension, have to ensure that the free end of the wing lifter or the like does not slip over the driver away but reliable attacks the driver and this can shift down. The extension may be formed as a separate part, which is plugged onto a conventional wing lifter. The driver on the drive rod of the espagnolette of the passive leaf may be an eccentric pin. Due to the eccentric adjustability of the driver, a fine-tuning can be made so that a reliable locking of the passive leaf can be done. As a driver on the drive rod comes any form of advantage into consideration. locking pin They are suitable because they are standard components already used here today. An (eccentric) adjustable locking pin then has the further advantage that its adjustment can also be done adjusting the closing behavior.

Further features and advantages of the invention defined by the claims will become apparent from the following detailed description of embodiments of the invention, with reference to the figures of the drawing.

In the FIG. 1 a window with a fixed frame 1 is shown, which has a small fixed center post. In the drawing plane right wing designed as a rotary wing 3 is arranged. Links is in the FIG. 1 to see a trained as a turn-tilt-wings active leaf 2. The active leaf 2 is locked by means of a central closure 6, which comprises a drive rod fitting, wherein the operation via the arranged in the central region, in the open position (rotational opening position) shown handle 7 takes place. When opening the handle 7 is moved upward or pivoted clockwise, wherein the inner vertical drive rod is moved in the direction of arrow 8. The inactive leaf 3 has an espagnolette fitting 11, via which the inactive leaf 3 is locked and unlocked. To operate the espagnolette 11, in particular at least for unlocking the espagnolette 11, a lever mechanism 12 is provided.

The FIG. 2 shows a perspective view of a portion of a drive rod fitting 20 for a passive leaf. The espagnolette fitting 20 has a faceplate 21 and a drive rod 22 arranged therebelow, which is bent in the region of a lever mechanism 23. The lever mechanism 23 comprises an operating lever 24, which is pivotable in a plane parallel to the wing plane of the inactive leaf. By pivoting the operating lever 24 from the locking position shown in a in the FIG. 3 shown unlocking position is a displacement of the drive rod 22, so that the inactive leaf 3 is unlocked and can be opened rotationally. The operation of the espagnolette 20 is based on the FIGS. 4 and 5 be explained.

The FIGS. 2 and 3 it can be seen that on the face plate 21 closing pieces 25, 26 are arranged, in which locking pins of the central closure 6 can retract for locking the active leaf 2. Upon pivoting of the handle 7 in the locking position locking elements of the shutter 7 are shifted on the side facing the inactive leaf 3 upwards. This means that the drive rod fitting 20 must be installed so that the openings 27, 28 of the closing pieces 25, 26 are directed downwards or are open at the bottom, so that corresponding locking elements can enter from below. Thus, in the installation position of the operating lever 24 is aligned downward and is pivoted to unlock the inactive leaf 3 upwards.

Of the FIG. 4 can be seen that the operating lever 24 is pivotally mounted on a fixed bearing 30 designed as a bearing block. At a coupling point 31, a toggle lever 32 is pivotally connected to the operating lever 24. The other end of the bell crank 32 has a driver 33 which projects with a driving pin 34 in a slot 35 of the drive rod 22. The driver 33 is pivotally connected to the toggle lever 32. Due to the pivotal movement of the operating lever 24 from his in the FIG. 2 shown locking position in the in the FIG. 4 shown unlocking position of the driver 34 has been moved in the direction of arrow 36, wherein the driving pin 34 at the boundary of the slot 35 and thereby the drive rod 22 has taken in the direction of arrow 36. The toggle lever 32 was therefore coupled to the coupling rod 37 with the drive rod 22.

As already mentioned above, the operating lever 24 is aligned in the installed position of the espagnolette 20 down. Due to its gravity, he is after a shift in the in the FIG. 4 shown unlocking position strive to pivot back automatically in the locked position. In this case, the driver 33 then moves in the opposite direction to the arrow. 36. The driving pin 34 can move in the slot 35 without abutting the drive rod 22. This means that the driver 33 is moved counter to the arrow 36, without taking the drive rod 22. The coupling at the coupling point 37 is thus canceled. When a return displacement of the operating lever 24 in its locking position, the drive rod 22 is not displaced.

In order to still be able to lock the passive leaf, therefore, other measures must be taken. This is in the FIG. 5 to see.

In the FIG. 5 is a wing lifter 40 to recognize, which is associated with the active leaf. It is therefore a fitting part, which is arranged on the moving leaf. If the active leaf is opened, then a lever of the wing lifter 40 is automatically deflected out of the plane of the wing. Becomes the wing closed again, the extension 41 comes with its leg 42 to rest against the return means 43, which is connected to the drive rod 22. This results in that the lever of the wing lifter 40 is pivoted. The leg 44 presses on the return means 43, which is connected to the drive rod 22 (see, for example FIG. 4 ). If the active leaf is closed further, the lever of the wing lifter 40 continues to pivot, so that the leg 44 is moved further and further in the direction of the arrow 45. (The representation of the FIG. 5 is opposite to the representation of FIG. 4 rotated by 180 °). Thus, the drive rod 22 is displaced to its locking position. The driver 33 is not displaced, since the operating lever 24 and thus also the driver 33 are already in the locking position. At the end of the displacement of the drive rod 22, the boundary of the elongated hole 35 is again on the driving pin 34, so that when actuated, the operating lever 24 can be unlocked again. The return means 43 is designed as an eccentric pin, so that a fine adjustment can take place. This can ensure that the locking is reliable.

In the FIG. 6 an embodiment of a drive rod fitting 50 is shown, which corresponds to the espagnolette 20 substantially. Therefore, the same reference numerals are used for corresponding components. The difference of the espagnolette fitting 50 to the espagnolette fitting 20 is that the espagnolette fitting 50 is installed in the reverse orientation. This means that the operating lever 24 is pivoted for pivoting from the locking position to the unlocking position downwards. In other words, the operating lever 24 in its locking position upwards. Thus, the drive rod 22 is moved in the opposite direction to unlock the passive leaf 3. This in turn means that to Lock the drive rod 22 must be moved upwards. In order to shift the drive rod 22 in the locking position, therefore, a driver 51 is provided, which projects through a slot 52 of the faceplate 21. The driver 51 is connected to the drive rod 22. To lock the driver 51 cooperates with a locking elements or another driver of the drive rod of the espagnolette fitting of the active leaf. When the active leaf is locked, its drive rod or the locking elements associated therewith are displaced in the direction of the arrow 53. As a result, the driver 51 is taken, so that the drive rod 22 moves in the direction of arrow 53. As a result, the driving pin 34 in turn comes into abutment against the boundary of the slot 35, so that subsequently can be done by a pivoting movement of the operating lever 24 again unlocking.

For example, between the toggle lever 32 and the operating lever 24 may be provided a spring element which tends to keep the operating lever 24 in its locking position. This has the consequence that due to the spring force of the spring element of the operating lever 24 automatically pivots back to a pivoting in the unlocked position in the locking position. This ensures that the control lever 24 is not in the traffic area when the inactive wing is unlocked.

The FIG. 7 shows an alternative embodiment of a part of an espagnolette fitting 60. A sectional view through the espagnolette fitting 60 in its locking position is shown in FIG FIG. 8a shown. The faceplate 61 covers the drive rod 62. The lever mechanism 63 in turn comprises an operating lever 64. The operating lever 64 is attached to a stationary bearing 65, which serves as a bearing block is formed, pivotally mounted. In contrast to the preceding embodiments, the pivot axis 66 is above the face plate 61. At a coupling point 67 of the operating lever 64 is pivotally connected to a toggle 68, which has a hook-shaped catch 69 at its free end. With its hook tip 70 of the driver 69 engages a stop 71 of the drive rod 62 at. Will now the operating lever 64 from his in the FIG. 8a shown locking position pivoted into its unlocked position, as shown in the FIG. 8b is shown, the driver 69 moves in the direction of arrow 72, taking the drive rod 62 with it. The knee lever 68 is thus coupled to the coupling rod 73 with the drive rod 62. During the pivoting movement of the operating lever 64, the toggle 68 moves in a slot 74 of the faceplate 61st

The operating lever 64 also has a slot 64.1, in which the toggle 68 comes to rest when the operating lever 64 in his in the FIG. 8a is shown locked position or home position.

When the operating lever 64 has been fully pivoted to its unlocked position and then again, as in the FIG. 8c can be seen, is pivoted into its locking position, the driver 69 is disengaged from the stop 71 of the drive rod 62. This is effected by a spring element 75, which in the FIG. 8b only hinted at. Due to the action of the spring element 75, the knee lever 68 is pressed in the direction of the operating element 64, so that it does not enter the recess 76 of the drive rod 62. If the operating lever 64 is therefore pivoted back, the drive rod 62 does not move in the opposite direction of the arrow 72. The drive rod 62 is bent in the region 77, so that the driver 69 unhindered relative to Driving rod 62 can move. The spring element 75 also causes the automatic and automatic reset of the operating lever 64 in its locking position.

The drive rod 62 has a return means 78, which has the same function as the return means 51 in the FIG. 6 , A provision is therefore made via a locking element or an associated with the drive rod element associated with the active leaf espagnolette fitting.

In the FIG. 9a It is shown that a coupling between the toggle 68 and the drive rod 62 can be made manually by the driver 69 of the toggle lever 68 is pressed against the spring force of the spring element 75 in the opening 76 of the drive rod 62. As a result, the hook tip 70 opposite stop 79 comes into contact with a boundary of the opening 76, in particular a stop 80 of the drive rod 62. Accordingly, if the operating lever 64 is pivoted back in the direction of arrow 81 in its locking position, the drive rod 62 through the stop 79 in the direction of arrow 82 taken, so that a locking of the inactive leaf takes place. The detachable coupling point 77 is therefore formed manually coupled.

The FIG. 9b shows the espagnolette fitting 60 after the operating lever 64 has been completely swung back after a manual coupling of the toggle lever 68 with the drive rod 62. The drive rod fitting 60 is now in a state from which an unlocking can take place by the operating lever 64 is pivoted to its unlocked position. Then the hook tip 70 engages again on the stop 71, which is bent out of the drive rod 62 to.

The FIG. 10 shows a drive rod fitting assembly 90 with the passive leaf associated espagnolette 60 and a power wing associated espagnolette 100. When the inactive leaf and aisle wing lie the espagnolettes 60, 100, as shown in FIG. 10 shown opposite. The drive rod fitting 100 has a gear 101, with the drive rod 102 of the espagnolette 100 can be moved. The drive rod 102 has locking means 103, which cooperates with the return means 78 for locking the passive leaf. In particular, in a locking of the active leaf by the gear 101, the drive rod 102 is moved in the direction of arrow 104. The locking means 103 takes the return means 78 in the direction of arrow 104, so that the drive rod 62 also moves in the direction of the arrow 104. As a result, a coupling is finally produced at the coupling point 77 between the driver 69 and the drive rod 62 again.

A part of the espagnolette fitting 90 is enlarged in FIG FIG. 11 shown. In the FIG. 11 It can also be seen that a locking element 105 is locked in a closing piece 106, rich on the face-plate 61, is locked. Thus, the active leaf is locked to the inactive leaf.

The FIG. 12 shows the knee lever 68 in an enlarged view. The knee lever 68 has at one end a passage opening 110, via which it is pivotally coupled to the operating lever 64 at the coupling point 67. It can be seen that the hook-shaped end, in particular the driver 69, is wider than the upper part of the toggle lever 68. This has the consequence that the toggle lever 68 can pass through the faceplate 61. However, the widened driver 69 is wider than the slot 74 in the faceplate 61, so that the driver 69 always is arranged below the face plate 61. In particular, the driver 69 can be held with its surfaces 111 and due to the spring action of the spring element 75 from below into contact with the faceplate 61 when the operating lever 64 is pivoted back from its unlocked position into its locking position.

The FIG. 13a shows a longitudinal section through a further embodiment of a portion of a drive rod fitting 120. Below a cuff rail 121, in turn, a drive rod 122 is arranged. A lever bearing 123 has an operating lever 124 which is pivotally coupled at a coupling point 125 with a toggle 126. In contrast to the previous embodiments, the toggle lever 126 is mounted with its other end to a stationary bearing 127, which is formed as a slot. For this, the free end 127 of the operating lever 124 is coupled to the connecting rod 128 at a Koppefstelle 128 with the drive rod 122. In particular, a projection 129 of the operating lever 124 abuts against a stop 130, which is bent out of the drive rod 122 at. If the operating lever 124 according to the FIG. 13b from its locking position ( FIG. 13a ) pivots, so the driver 129 and thus the drive rod 122 moves in the direction of arrow 131. This will unlock the inactive leaf. The operating lever 124, more precisely the driver 129 of the operating lever 124, projects through a slot 132 of the face-plate 121.

If the operating lever 124 pivoted back, in particular in the position according to FIG. 13c , so the coupling is released at the coupling point 128. The driver 129 no longer acts on the stop 130. The drive rod 122 remains in its unlocked position. The operating lever 124 thus performs an idle stroke, as it were. On the driver 129, a hold-down may be pushed through the opening 135, which is in particular longer than the width of the slot 132 in the face-plate 121st As a result, it can be prevented that the operating lever 124 with its driver 129 lifts upwards from the face-plate rail 121. In the relative movement of operating lever 124 and face plate 121 may cause friction. To reduce this, the end of the operating lever 124 may be provided with a lubricious material, such as plastic. Also, the espagnolette fitting 120 has return means 51, through which the drive rod 122 can be moved back into its locking position.

In the preceding embodiments, espagnolette fittings have always been shown which have a drive rod which is movable in one direction only. However, embodiments are also conceivable in which the drive rod is in several parts, wherein different parts of the drive rod are moved in different directions. This can be done, for example, that according to Figure 14a a drive rod portion 140 is driven via a lever gear, wherein a part of the drive rod portion 140 cooperates with a stationary mounted pinion 141. The pinion 141 also meshes with another driving rod portion 142. Accordingly, if the driving rod portion 140 is moved to the right, for example (see FIG FIG. 14b ), so also the drive rod portion 142 is moved to the left, so in the opposite direction. In this way, simply a stroke reversal can be realized. The in the Figures 14a, 14b shown stroke reversal can be used in each of the above and below described espagnolette fittings.

The FIG. 15 shows a highly schematic of another embodiment of an espagnolette fitting 150. The operating lever 151 is fixedly mounted on the face plate 152 pivotally mounted on a stationary bearing 165. At a coupling point 153, the operating lever 151 is pivotally connected to the toggle 154. In the region of the coupling point 153, a spring element 155 is provided, which endeavors to move the operating lever 151 and the toggle lever 154 in a parallel alignment with each other, or to pivot the operating lever 151 in its locking position.

At the coupling point 156 of the toggle lever 154 is coupled to a stop 157 of the drive rod 158. For this purpose, the free end 159 designed as a driver of the toggle lever 154 is hook-shaped. If the operating lever 151 is pivoted back again after a displacement of the drive rod 158, the toggle lever 154 is released from the stop 157. This is effected by the spring element 155. The distance between the stops 157 and 160 is dimensioned so that the hook-shaped end 159 can be reliably released from the stop 157. If a displacement of the drive rod 158 in a locking position by means of the operating lever 151 carried, the toggle 154 can be pressed against the spring force of the spring element 155 down so that the hook-shaped end 159 of the bell crank 154 abuts the stop 160 and thus the drive rod 158th in the locking position entrains. In the embodiment according to FIG. 15 Accordingly, the coupling point 156 is the releasable coupling point.
