Description

The invention relates to a locking device having connecting rods on the embossing sash of double-leaf windows or doors without mullions, in which the sash and the fixed frame are composed of metal or plastic hollow profiles.

In such windows or doors, a so-called forend profile is connected to the opening-side spar of the tucking wing as an external stop for the overlapping wing. That is why the concealing wing of such windows or doors is also referred to as a "sash".

In the wing profile is a, for. B. T-shaped or dovetail-shaped, undercut guide channel for receiving displaceable connecting rods. The drive rods provided on the striking wing or on the sash are used to lock the same in the closed position on the fixed frame. There are two drive rods on the opening-side spar of the underlapping wing or sash which can be moved in opposite directions by means of a special actuation gear, the so-called sash wing gear.

The embossing wing or sash is locked via the free ends of the two oppositely displaceable connecting rods, which come into operative connection with bolt engagements on the fixed frame.

Closure devices of the generic type having connecting rods have long been known in practical use and by obvious prior use on French sash windows.

On the one hand, it is part of the state of the art to provide the drive rods that can be displaced in opposite directions by the sash operating gear in the guide channels on the opening-side spar of the tucking wing and to anchor the associated operating gear lying above the guide channel directly on the wing profile by means of screws. Here, however, the cuff profile must be provided with a recess or notch, which is able to accommodate the housing of the cuff actuating gear in its entire length and width.

In another prior use, the drive rods of the sash lock are also housed in guide channels on the opening-side spar of the tucking wing, but here the sash actuation gear is screwed onto the outside of the sash profile. Here, it is not only necessary to provide large milled recesses in the sash profile for the passage of the driver pins of the sash actuation gearbox, but also with the connecting rods that can be displaced in the wing-side guide channel, spacer bushings must also be riveted in order to ensure the relatively large distance between the connecting rods and the sash actuation gearbox to bridge.

Finally, due to DE-Gbm 71 44431, it also belongs to the state of the art, on the one hand, to accommodate the connecting rods in guide channels of the forend profile and, on the other hand, to fasten the sash actuation gear on the outside of this forend profile.

In this case, only slots need to be provided in the faceplate profile, by means of which pins located on racks of the faceplate operating gear can be brought into coupling engagement with the drive rods.

In this arrangement, however, the closing forces to be applied are absorbed almost completely by the faceplate profile, so that a stable connection must be established between this and the opening-side spar of the tucking wing via a large number of screws.

Practice has shown that with the different connecting rods having locking devices on the embossing sash of the sash-casement windows or doors, it is necessary in each case because of the different installation conditions to at least also produce different sash-casement actuation gears and keep them in stock.

However, their installation is also complex because extensive machining operations have to be carried out on the respective forend profile before this can be properly connected to the opening-side spar of the tucking wing.

The purpose of the invention is to remedy the shortcomings of all the locking devices having the above-described connecting rods on the tucking wing of double-leaf windows or doors. Therefore, the invention has for its object to provide a closure device, namely a sash lock, of the type described, in which or in particular the sash actuation gear in one and the same design can be easily and securely installed on the opening-side spar of the embossing wing without this complicated and difficult machining operations must be carried out on the forend profile to be provided there.

The fiction, contemporary solution to this problem is essentially characterized by the combination of features that the housing of a rotary actuator, z. B. a pinion, and two by this oppositely movable thrust members having Be Actuating gear can be aligned and locked against displacement in the guide channel of the tucking wing via an undercut foot part connected to it;

• that protruding pins of the thrust members from the housing of the actuating gear can be inserted into coupling holes of the drive rods displaceably received in the guide channel of the embossing wing;
• that the cuff profile overlaps the actuating gear anchored to the tucking wing and 'the connecting rods as a cover;
• that the faceplate has a hole in the axial alignment with the nut or driver pin of the rotary drive member seated in the actuating gear.
• and that an operating lever with a neck part can be inserted through the hole of the faceplate profile into the nut or the driving pin of the rotary drive member.

By carrying out these measures together, it is possible with little technical effort to attach the sash lock securely and easily directly to the underpinning sash, irrespective of the cross-sectional profile of this and the cuff profile assigned to it.

According to the invention, it has proven to be particularly advantageous if the foot part is fixed, in particular in one piece, connected to the housing base of the actuating gear and is equipped with threaded bolts as clamping parts which can be braced against the bottom of the guide channel or into holes in the same by holes in the cover plate of the gear housing are positively screwed.

According to another feature of the invention, it is also important that the pins of the thrust members protrude through elongated holes in the housing base of the actuating gear, the ends of which facing each other are at a distance from the ends of the base part formed on the housing base.

According to a further feature essential to the invention, the rotary drive member of the actuating gear can have a polygonal, in particular square, pin with a coaxial threaded hole as a driving pin, and the operating lever can hold a compression spring in its neck, which has a corresponding polygonal recess, which is supported against the end face of the driving pin, the operating lever is continuously adjustable axially by a screw that can be screwed into the threaded hole against the force of the spring on the polygonal journal.

Furthermore, it is provided that engaging with the free ends of the drive rods via a hole-pin coupling in the guide channels of the embossing wing latch slide.

For permanent functional reliability of the sash operating mechanism, it is also important that the thrust links are guided on four sides on the one hand by the pins which reach into the elongated holes of the housing base and on the other hand between the housing walls and a longitudinal bar provided on the housing base. In this longitudinal bar on the one hand the bearing bore for a track pin of the rotary drive member and on the other hand two threaded holes for the threaded bolts forming the clamping parts can be formed and this longitudinal bar can also carry rivet pins for fastening the housing cover.

In Fig. 1 of the drawing, a two-leaf window is shown, the fixed frame 1 is designed without a central post.

The narrow wing 2 hinged on the right forms the overlapping wing and is designed as a tilt and turn wing. The wider wing 3 hinged on the left, on the other hand, forms the defeating wing and is only used in the fixed frame 1 as a rotating wing.

In FIG. 2, the opening-side wing spar 4 of the overlapping wing 2, the opening-side wing spar 5 of the overlapping wing 3 and the cuff profile 6 assigned to the two wing spars 4 and 5 are shown in a spatial exploded view.

As can be seen from FIG. 2, approximately T-shaped or dovetail-shaped undercut guide channels 8 are formed in the mutually facing profile surfaces 7 of the two wing spars 4 and 5, each directed to the wing plane, each for receiving drive rod profiles 9 'and 9 " serve.

By means of the drive rod profiles 9 ', not only locking members are actuated on the overlapping sash, but also the necessary changeover of the rotary tilt joints for the sash takes place as a result.

By means of the drive rod profiles 9 "in the tucking wing, the latter is only locked in its closed position on the fixed frame.

As can be seen particularly clearly from FIG. 3, the cuff profile 6 is connected to the opening-side upright spar 5 of the tucking-in wing 3 by screws 10 such that it can form the sealing stops for the opening-side spar 4 of the overlapping wing 2.

In the case of double-leaf windows or doors without a mullion - the so-called sash windows or doors, - it is important that the - also called sash - embossing sash 3 receives a secure locking in its closed position on the fixed frame 1, because on the one hand there is one safe and joint-tight locking of the overlapping wing 2 is dependent; on the other hand, only when the overlapping wing 2 is designed as a tilt-and-turn wing is it ensured that the tilting bearing is functionally reliable.

To lock the embossing wing 3 on the fixed frame 1, an espagnolette lock is therefore used, which has an actuating gear 11, as can be seen from FIGS. 4 to 8. This actuating gear 11 has a gear housing that is composed of a box-shaped lower housing part 12 and a housing cover 13 closing it.

In the box-shaped lower housing part 12, two thrust members 14 ', 14 "are guided, which are in engagement with a rotary drive member 15, for example as a pinion, on opposite circumferential sides via so-called pinion teeth 16 and are thereby moved in opposite directions. Each thrust member 14', 14" carries a free pin 17 'or. 17 ", these pins 17 'and 17" each through a longitudinal slot 18' or. 18 "in the bottom 19 of the box-shaped lower housing part 12 protrude.

The rotary drive member 15 is aligned on the one hand with a molded-on track pin 20 in a preferably bulged bearing bore 21 of the box-shaped lower housing part 12 and on the other hand with a bearing pin 22 in a bearing bore 23 of the housing cover 13. The free end of the bearing pin 22 has a polygonal cross-section, for example a square cross-section, and forms a driver pin on which an operating lever 25 with a polygonal recess 27 formed in its neck part 26 can be attached.

The flawless longitudinal guidance of the thrust members 14 'and 14 "in the housing of the actuating gear 11 is ensured, on the one hand, by the pins 17' and / or through the longitudinal slots 18 'and 18" in the housing base 19. 17 ". On the other hand, however, a longitudinal bar 28 is also formed on the housing base 19, which causes each thrust member 14 'or 14" to have a four-sided longitudinal guide between the box-shaped lower housing part 12 and the housing cover 13.

The longitudinal bar 28 also carries a rivet pin 29 at each of its ends, with the aid of which the housing cover 13 can be fixed precisely and securely on the box-shaped lower housing part 12.

A base part 30 of essentially T-shaped cross section adjoins the underside of the housing base 19, preferably integrally formed thereon, the profile shape of which essentially corresponds to the cross section of the drive rod 9 ″ shown in FIG. 2 Push the entire actuating gear 11 into the correspondingly profiled, undercut guide channel 8 which, according to FIGS. 2 and 3, is located on the rebate surface 7 in the spar 5 on the opening side of the deflecting wing 3.

If the actuating gear 11 is inserted with its foot part 30 into the guide channel 8, the pins 17 'and 17 "of the thrust members 14' and 14" must be hooked into corresponding coupling holes 31 of the two connecting rod sections 9 ", which are slidably received by the guide channel 8 will.

The exact alignment and mounting of the actuating gear 11 in the guide channel 8 is effected via the foot part 30. Threaded bolts 32, which are held in continuous threaded holes 33 in the longitudinal bar 28 or the foot section 30 and are accessible by means of a tool, for example a socket wrench, through holes 34 in the housing cover 13 serve to fix the position or lock the actuating gear 11 in the guide channel 8. The threaded bolts 32 are thereby braced against the bottom of the undercut guide channel 8 and thus establish a clamping connection of the actuating gear 11 with the wing spar 5 via the foot part 30. According to FIG. 9, the free ends of the two connecting rod sections 9 ″ likewise have holes 35, into which locking slides 37 can be hung by means of pins 36, which are also slidably received in the undercut guide channel 8. These locking slides 37 cooperate with locking plates inserted into the two horizontal spars of the fixed frame 1 and, when they are in engagement, securely fix the embossing sash 3 to the frame 1.

Only when the actuating gear 11, the drive rod sections 9 ″ and the locking slide 37 have been inserted into the guide channel 8 on the opening-side spar 5 of the embossing wing 3 is the faceplate profile 6 also fastened to the latter by the screws 10, as can be seen in FIG. 3 .

The faceplate 8 is only equipped in the axial alignment with the driver pin 24 of the actuating gear 11 with a hole 38 through which the operating handle 25 can reach with its neck part 26.

Since the faceplate profiles 6 can have different heights in different profile systems, it is important that the relative position of the operating handle 25 to the driving pin 24 of the actuating gear can be continuously adapted to these different heights.

In order to achieve this, the driver pin 24 has a concentric threaded bore 39 with which a connecting screw 41 can be brought into engagement through a countersunk hole 40 in the neck 26 of the operating lever 25. In the polygonal recess 27 of the operating lever 25, a compression spring 42 is arranged coaxially to the connecting screw 41, which rests against the end face of the driving pin 24 and forms an elastically flexible spacer, which prevents undesired axial displacement of the neck 26 on the driving pin.

In the closure device described above, it is particularly important that all of its functional parts are guided or held by the undercut guide channel 8 on the opening-side spar 5 of the underpinning wing 3. In this way it is achieved that the cuff profile to be connected to the rebate surface 7 with the opening-side spar 5 of the embossing wing 3 merely forms the opening-side sealing stops for the overlapping wing 2 and does not have to absorb any stresses that result from the actuation of the closure device, although the actuation gear 11 protrudes from the guide channel 8.

It is also important that for the closure device described above, no cutouts or notches have to be produced on the opening-side spar 5 of the underpinning wing 3 or on the faceplate profile 6. Only the simple bore 38 is to be provided in the faceplate profile 6 for the operating lever 25 to reach through.

The above-described and claimed espagnolette lock is used in double-leaf windows or doors without a mullion in the fixed frame to fix the embossing wing in its closed position and is constructed so that it can be used in one and the same design without problems in connection with a large number of different profile systems can be.
