The closure device is attached to the hinged side of the door or window. It has a closure element (2) attached to the door or window frame (26). There are sliding bolts (3), secured to the door or window (25), selectively brought into engagement with the closure element via an operating drive. The sliding bolts are provided by eccentric bolts supported by a drive rod (5) with a claw opening at one end.

Description

The invention relates to a connecting rod locking device according to the preamble of claim 1 or 2. Such a connecting rod locking device is known from DE-A-1816581.

With the usually as locking devices for doors, Windows or the like Espagnolette fittings are the ones that serve as locking elements Lock bolts and the associated strikers designed so that they are in the closed switch position of the Espagnolette fitting with parallel to the wing and Support surfaces facing each other at frame level can. This type of drive rod locking devices is always an advantage if each of them Bolt and a striker formed Locking points have an installation position by a between the two window and door elements, e.g. the Frame and the wing provided hinge or Joint axis is removed.

However, the above-mentioned configuration of the Bolts and strikers when the Locking points - like a so-called Central locking usual - also between those bars, for example, wing and frame spars can be installed should or must be secured by a hinge or Joint axis are connected. This is for example with turn and tilt and turn windows, doors or the like. Regular practice. Because in such a Installation with open around the relevant hinge axis Wings from the user via the actuating gear - consciously or unconsciously - a malfunction of the Espagnolette fitting made, then meet at one subsequent closing movement of the wing bolt and Strikes blocking each other in an undesirable manner. They are exposed to stresses that lead to their Can cause damage or even destruction.

To avoid these disadvantages of the known drive rod locking devices with conventional design of Bolts and strikers are therefore different Suggestions have been made.

From DE-A-18 16 581 it is used to prevent damage already known on strikers and locking bolts, these with coordinated conical inner and outer surfaces to equip them with one between sash and frame To give installation position when closing the wing too in the closed switch position of the actuating gear can cause no damage. This is achieved by that certain conical surface areas of strikers and Latching bolts affect circular arcs that are approximately in their center the hinge axis between sash and frame or between two wings installed directly next to each other.

It is also already provided that the movable locking member as a U-shaped claw having the conical inner surfaces is formed, which is difficult to turn with an eccentric bolt on the drive rod riveted or caulked. The claw is around one of the eccentric bolts spaced bearing axis pivotable on the drive rod. That claw is a fixed locking bolt with conical outer surfaces assigned. The eccentric bolt can tilt the Claw can be achieved, whereby there is a variation of the closing pressure.

Furthermore, an espagnolette lock is known from EP 0 575 784 A1 become to the use of conventional connecting rod fitting components provides that the bolt journals, if any, are mounted eccentrically wear sleeves near the hinge or hinge axis, one have a beveled, for example conical, outer contour. Let it through not only use the usual drive rod fitting components or retrofit but also - using special to the Conical shape of the sleeves adapted bolt interventions - a flawless Ensure the function of the connecting rod fitting components.

For the same purpose are with DE-C-23 35 964 propeller locking devices have also been proposed been in which the locking bolts a mushroom-like Shape and sit on a connecting rod, the one behind a faceplate guided longitudinally as well as Bending spring is supported. In this case, the mushroom head-like locking pin after a previous one Malfunction of the drive rod during the closing movement of the Wing on the end face of the striker, then gives way the connecting rod resiliently springs into the fitting groove until the center perpendicular of the deadbolt and the Stand perpendicular to each other of the striker and now the mushroom head of the bolt into the striker can dip under spring back of the drive rod.

A disadvantage of this known connecting rod locking device is in particular that the mushroom head of the Bolt has only a relatively short contact surface and is therefore subject to a correspondingly high level of wear.

A common disadvantage of both known embodiments of espagnolette locking devices can be seen in that so-called central locks with near Hinge or hinge axes between sash and frame arranged locking points special fitting components require. These must be in addition to the hardware components be made in a conventional manner and stored. The effort for such central locks is therefore considerably.

The present invention aims to avoid the Disadvantages of the known prior art from and represents the task, therefore, is to make the greatest possible use of Fitting components of a conventional type, so-called Standard fittings, but allow theirs Functionality also when installing near articulated axes to ensure permanently. In particular, it should be sure that with the help of the eccentric adjustable bolt given possibility of Pressure regulation between the via the connecting rod locking device interlocking windows or Door elements (wings and frame) are fully preserved.

This object is achieved according to the invention by the characterizing features of claims 1 or 2.

Known, eccentrically adjustable locking bolts can therefore at any time in an advantageous manner an L- or U-shaped claw is operatively connected to realize the idea of the invention.

In practice, it has proven to be useful Bearing axis the end of the claw distant from the opening end assign them and through a hole in the drive rod screw-in screw, in particular a sheet metal driving screw, to build.

To relieve the screw serving as the bearing axis from to the claw exerted forces, can the claw on the back an additional one parallel to the bearing axis extending and lying piece approach, which engages in a suitable opening of the drive rod.

If with an espagnolette locking device according to the invention the strikers from locking cams exist, then it is also advantageous if the Closing cams taper away from their mounting base taper and the inner surfaces of the L- or U-shaped Bolt claw an inclination adapted to this conicity exhibit.

It is also useful to use the closing cam To equip the mounting base with a spigot that extends parallel to the cone axis and thereby into an am Window or door element, e.g. B. on the fixed frame or one Middle wing, provided drill hole can be used. The Closing cams can also be one with the longitudinal axis of his Aligned through hole for mounting a mounting screw included.

By working together with the help of the eccentric adjustable latch bolt pivotable L or U-shaped Claw with the eccentrically adjustable conical Closing cams can have a particularly large adjustment range mastered and consequently also the pressure effect of the Espagnolette locking device varies within wide limits be, if also the pin approach of the locking cam is arranged eccentrically to the cone axis.

in a detailed representation a horizontal section through a window can be seen, in which, for example, the left wing - as the side wing - occupies the closed position, while the right wing - as the middle wing - is in a rotational position that is open at a slight angle with respect to the left wing.

1 to 4 of the drawing is a Functional essential section of an espagnolette locking device 1 for the sash of windows, doors or Like. Shown, which as a striker 2 Closing cam used with which - as a locking member - one in Cross-section U-shaped and at least one-end open claw 3 can interact.

According to FIG. 1, the claw 3 is a faceplate 4 and a drive rod 5 guided behind this longitudinally sliding having connecting rod fitting 6 assigned. For Longitudinal displacement of the drive rod 5 relative to the faceplate 4, a conventional (therefore not shown) Actuator used.

The drive rod 5 basically carries as locking members 7 conventional locking bolts, which preferably one have cylindrical bolt head 8, which before Face of the faceplate 4 is, as is clear Fig. 1 can be seen. With one on the back of the Bolt head 8 passes through eccentric shaft 9 each acting as a bolt Bolt member 7 an elongated hole 10 in the faceplate 4 and is on the back of it with an eccentric 9 aligned pin 11 with the drive rod 5 in connection. The pin 11 is in a hole 12 of the drive rod 5 riveted or caulked to prevent rotation.

It can be seen in FIGS. 1 and 2 of the drawing that the Bolt head 8 of the locking bolt serving as locking element 7 to the eccentric shaft 9 and the pin 11 connected thereto is arranged with the eccentricity 13.

In the free end face of the bolt head 8 are as Interventions for an operating tool on the one hand Diametral slot 14 and on the other hand a polygonal recess 15 molded. The diametral slot 14 can be used as Tool engagement for a screwdriver while serving yourself with the polygonal recess 15 accordingly can engage profiled socket wrench. With The respective tool can be used as a locking member 7 locking bolts from its neutral position according to Fig. 2 continuously up to the extreme left position 3 or up to the extreme right position shown in FIG. 4 relative to the drive rod 5 and the faceplate 4 of the Espagnolette fitting 6 can be adjusted.

Normally, the locking head 8 acts as locking element 7 serving bolt directly with a striker in the way together that in the closed switch position the drive rod is parallel to the sash and frame level can support directed surfaces against each other.

But this means that they are designed as locking bolts Bolt members 7 having espagnolette fitting 6 with relatively little additional construction work there too Use can be taken where there is a lock on the Windows and doors in the Proximity of their hinge or hinge axes is necessary Claw 3 already mentioned above, which is still used retrofittable additional functional part with an as Closing cam designed striker 2 can interact.

For this purpose, the claw 3 can be spaced apart with the drive rod 5 that formed by the eccentrically adjustable locking bolt Bolt member 7 in at least about a bearing axis 16 limited pivotable connection. This is simply with the help of a screw 17, in particular a self-tapping screw possible, one with the bearing axis 16 aligned passage opening 18 passes through the claw 3 and can be anchored in a hole 19 of the drive rod 5. The claw 3 has an approach 20, which by the Elongated hole 10 of the faceplate is passed and bears against the drive rod 5. Approach 20 goes again a support projection 21, which is parallel to the bearing axis 16 extends and into a matching opening 22 of the Driving rod 5 engages. This support approach 21 has Interact with the opening 22 the task of excessive Intercept lateral forces, and thus as a fastener used to relieve screw 17 of this.

It is also important that the claw 3 in the space between their bearing axis 16 and the claw opening 23 a longitudinal engagement slot 24 has, which is suitable for the bolt head 8 of the Lock bolt designed locking member 7 with as possible little side play, but sufficient longitudinal play record (see Fig. 2 to 4).

Through the already mentioned above and especially from the 2 to 4 removable adjustability of the locking head 8th around the eccentric 9 can the claw 3 with her Claw opening 23 as required from the neutral base or 2 continuously up to one or bring other extreme tilt positions, as either the Fig. 3 or Fig. 4 can be seen.

5 of the drawing is an installation example for a Espagnolette locking device 1 shown by easy retrofitting of a conventional one Espagnolette fitting 6 with the claw 3 in the area of Locking elements 7 usually designed as locking bolts has been created.

The example of FIG. 5 is of a three-leaf window without a fixed center post, essentially only the right one Vertical spar 25 of the left wing - side wing - and the left vertical spar 26 of a middle wing. Both Vertical bars 25 and 26 occur in the closed position of the Window - so if all wings in a common plane are in direct connection with each other. That is, the claws 3 of the built in the vertical beam 25 Espagnolette locking device 1 can with the as Closing cams made on the vertical struts 2 26 are brought into locking engagement.

So that the left vertical spar 26 of the middle wing around the Axis 27 of its joints 28 easily opened and can be closed without first on the vertical beam 25th the left side wing the claw 3 by pressing the Espagnolette fitting 6 from the closing cam designed strikers 2 on the vertical spar 26 of the Middle wing must be disengaged are special Precautions taken. These are that the Strikers 2 have conical lateral surfaces 29. This and the cooperating beveled inner surfaces 30 tangent to the locking lugs 31 of the claw 3 Circular arcs, the center of which at least with the hinge axis 27 approximately coincides, as in Fig. 5 of the drawing is recognizable.

As already described above, the can in the Vertical spar 25 of the left wing built-in - special connecting rod fitting 6 can be created simply by with each bolt head 8 its in a conventional manner as Latching bolts 7 have a claw 3 subsequently coupled and pivotable on the Drive rod 5 is anchored. On the left vertical spar 26 of the Each claw 3 needs a middle wing as a striker 2 only one protruding over the fold surface Locking cams assigned to the conical lateral surface 29 become. Both from Fig. 1 and from Fig. 5 can be remove that the locking cam of the strikers 2 from its mounting base 32 tapers away conically. According to Fig. 5 have the inner surfaces 30 of U-shaped in cross section designed claw 3 adapted to this conicity Inclination.

Each striker 2 can be a fastening base 32 Have pin extension 33 which is parallel, however preferably extends eccentrically to the cone axis 34. The Eccentricity 36 of the cone axis 34 to the longitudinal axis 35 of the Pin projection 33 can be seen in Fig. 1 of the drawing. It can also be seen in FIG. 1 that the Striker 2 conical locking cam one with the Longitudinal axis 35 of the pin extension 33 in alignment Through hole 37 has a mounting screw 38 can accommodate. With the neck 33 of his Mounting base 32, each latch member 7 can be in a bore 39 inserted on the fold circumferential surface of the vertical spar 26 and then with the help of the fastening screw 38 be anchored. The eccentricity 36 between the Longitudinal axis 35 of the pin extension 33 and the cone axis 34 of the designed as a locking cam striker 2 makes it possible in cooperation with the swivel adjustment of the Claw 3 for the purpose of pressure regulation between the Vertical bars 25 and 26 of the two each other adjacent wings a relatively large adjustment range bridge. 1 in particular can still be seen that the claw 3 at her averted from the opening end 23 End has an extension arm 40, which turns out to be Abutment constantly against the face of the faceplate 4 supports to prevent the claw 3 from touching her Opening end 23 can lift off the faceplate 4.

Deviating from that shown in the drawing The embodiment is the claw 3 with an only L-shaped Cross section or with only one locking lug 31 usable if care is taken to ensure that this or them L-flange forming the intended as striker-2 Closing cam on its from the opening direction of the window or reach behind the side facing away from the door can. But then there must be two for right and left stop different claws 3 are kept ready.
