Locking device for windows, doors or the like

809882/0320

The invention relates to a locking device for windows, doors or the like. With a slidably guided on the casement frame Driving rod, which carries at least one locking member projecting perpendicular to the driving rod, which in the locking position with an associated bolt or bearing part of the window frame is in engagement and which is opposite the sash transverse to the pushing direction the connecting rod is adjustable.

Locking devices with adjustment facility for the locking member are known in various designs.

In a device known from DT-AS 18 16 581, the locking member is designed as a rolling pin, which is in the closed position engages behind an assigned edge of a strike plate attached to the frame. The rolling pin has one on a bolt freely rotatable bushing, the peripheral surface of which cooperates with the strike plate. The bolt has an eccentric attachment which is riveted or caulked in the connecting rod so that it is difficult to rotate is. On its free end face, the bolt has a radial slot for the engagement of a screwdriver for rotation the eccentric axis of the approach. This rotation has the consequence that the bolt and with it the freely rotatable bushing in the thrust direction and can be adjusted transversely to the sash frame. The adjustment taking place transversely to the pushing direction of the push rod influences the closing pressure between the sash frame and the frame. This possibility of regulating the closing or contact pressure between The casement frame and the frame allow for a compensation of positional inaccuracies between the parts of the locking device. Such positional inaccuracies can have various causes, e.g. in the imprecise stop of the parts of the locking device, be due to the constant change in temperature, the humidity or the paint. These influences can lead to that the locking device can either only be operated with difficulty or not at all, or that it only has one

809882/0320

Insufficient locking pressure: causes.

In the known, on the use of an eccentric roller pin based wing locking device there is a risk that the more or less fixed riveting of the bolt approach loosened in the connecting rod by repeated readjustments and the roller pin no longer moves to a position that has once been set can maintain.

From DT-PS 1 148 467 there is also an eccentric rolling pin known, in which there is no risk of loosening with repeated adjustments. This rolling pin that is anchored directly on the casement or on the frame and not on a movable connecting rod, can before its adjustment loosened in the anchorage and then reattached. However, this is with a considerable amount of components and one handling of several items connected.

From DT-GbmS 76 23 990 it is also known to attach the locking pin immovably to the drive rod and the Driving rod itself can be adjusted transversely via an adjusting device with respect to its guide element which is fixedly arranged on the frame close. In this known embodiment it is objectionable that the adjustment of the drive rod for the purpose of Adjustment of a locking member arranged at a certain point on the drive rod inevitably leads to a change in location the drive rod gives rise to its guidance over its entire length, which may be undesirable, for example, if several locking members are arranged on the drive rod, which then no longer individually in the optimal position can be easily adjusted. Also requires the lateral adjustability of the entire drive rod for the purpose of Adjusting the locking member an increased possibility of movement of the drive rod in the wing arm receiving it,

809882/0320

which means that a drive rod receiving groove in the sash must be larger than it would have to be if the Guiding the drive rod with respect to its carrier would be invariable. This widening of the groove for the connecting rod in the casement is not always desirable.

In this embodiment, there is also the risk that the head of the eccentric adjusting member will move laterally Loading of the locking member and simultaneous actuation of the fitting (displacement of the connecting rod) on the inner surfaces the long slot of the faceplate rubs and self-adjustment due to the frictional forces that occur there of the eccentric adjusting member becomes possible.

The invention is based on the object of a locking device indicate which avoids the disadvantages of the known locking devices and which in particular the requirements met that even after repeated adjustments, the locking member does not experience any loosening that leads to an unintentional automatic adjustability during operation could lead to the construction and in particular the handling of the adjustment device It remains simple that the adjustment of a certain locking member in the presence of several locking members on a drive rod has no influence on the position of the other locking members, and that a groove in the sash frame that receives the drive rod can remain essentially limited to the width of the connecting rod.

To solve this problem, it is proposed according to the invention that that a locking member mounting lever extending essentially parallel to it is pivotably mounted on the drive rod

809882/0320

/ fir

is that the locking member is arranged on the locking member support lever and that the locking member support lever is adjustable and lockable relative to the drive rod in its pivot position.

The locking member mounting lever can be adjusted relative to the drive rod by means of an eccentric adjusting member be, which is rotatably mounted on the drive rod with difficulty and with its eccentric part in engagement with the latch member mounting lever is at a point outside of its pivot axis. Any loosening the difficult storage of the

809882/0320

Eccentric adjusting member on the drive rod is in this embodiment therefore not critical, because on the eccentric adjusting member when the locking member interacts with a bolt or Bearing part of the window frame no significant torques occur, in particular no torques caused by a frictional Sliding of the locking member on the locking or bearing part are caused, so that the eccentric adjusting member even then the locking member can hold the storage lever in the desired position if a certain loosening of its storage should have occurred in the connecting rod.

According to a preferred embodiment, the eccentric part can be inserted into a recess or a fork of the locking member mounting lever intervention. This engagement of the eccentric part with the recess or the fork is usually designed so that the Latch member support lever is fixed in both pivot directions by abutment with one edge each on the eccentric part.

As a fundamental advantage of the training according to the invention it should be added that with the locking device according to the invention with the desired transverse adjustment of the locking member, essentially no longitudinal adjustment of the locking member goes along in the direction of the drive rod, since the locking member mounting lever are designed to be correspondingly long can. This advantage is especially evident compared to those known embodiments in which a Driving rod is rotated directly eccentrically mounted pin.

To with a relatively small angular deflection of the locking link mounting lever To achieve a relatively large transverse adjustment of the locking member, it is advisable to use the locking member to be arranged on the latch member support lever outside of its pivot axis. With a circular design of the locking member

809882/0320

it is even necessary that the locking member lies outside the pivot axis of the locking member mounting lever, otherwise by pivoting the locking member mounting lever, an adjustment of the locking member would not be achievable. For example can the eccentric adjusting member on the locking member mounting lever at a point between the pivot axis of the Attack latch link support lever and latch link.

If the locking member is not round, it is also conceivable to place it in the area of the pivot axis of the locking member mounting lever to be arranged, because then due to the non-circular shape of the locking member its projection transversely to the drive rod length direction in the case a pivoting of the locking member support lever is changed even when the locking member is in the area of the pivot axis is arranged.

The drive rod can in the locking device according to the invention guided in a manner known per se on the inside of a faceplate connected to it to form a driving rod assembly unit be. In this case, the locking member mounting lever will rest on the outside of the faceplate; the storage of the positioning lever on the drive rod then takes place through a pivot pin connecting the drive rod to the locking link bearing lever, which passes through an elongated slot of the faceplate; likewise the eccentric adjusting member becomes the long slot of the faceplate take action. The pivot pin and / or a centric part of the eccentric adjusting member (centric with respect to the Bearing axis of the eccentric adjusting member in the drive rod) can take over the function, the drive rod in the elongated slot laterally to lead essentially immovable.

When the locking member support lever is relatively long, so that its exclusive connection with the drive rod by means of of the pivot pin unintentional bending away of the pivot pin distal end of the locking link support lever from the

809882/0320

--Η—

Could cause faceplate, so you can look at that of the pivot axis of the locking member support lever remote end of the locking member support lever arrange a rear engagement member, which penetrates the long slot of the faceplate and engages behind the inside of the faceplate, then the long slot of the Forend rail penetrating part of the rear gripping member within the elongated slot transversely to its longitudinal extent, play of movement must have.

The inventive design of a locking device is particularly suitable for locking the casement with the frame in the tilting bearing area. For this purpose, the locking device according to the invention can be arranged at the lower end of a tilting bearing-side vertical drive rod. The particular suitability of the locking device according to the invention as a tilting bearing lock results from the fact that the use of circular locking pins for the tilting bearing locking is often avoided because it is difficult to let such circular locking pins interact with the tilting bearing-side locking or bearing part in the sense of a desired lift-out protection. The creation of such an anti-lift device using a circular bolt pin would require a very complicated shape of the frame-side bolt or bearing part, especially if there is also the requirement that this bolt or bearing part should be usable on the right and left. The inventive design of the locking device now allows non-circular locking members to be used and adjusted, which is not readily possible with locking members that are eccentrically mounted directly on the drive rod.

Another, preferred application of the locking device according to the invention is the locking of a deployment rod on the upper sash leg, which on the frame

809882/0320

-Type-

is pivotably articulated in the axis of rotation of the sash and the pivot bearing of the sash frame in the locked position takes over. For the purpose of locking the opening rod to the upper sash, the use of a locking link is circular Cross-section, which could be mounted eccentrically on the associated drive rod, is unfavorable because you endeavors to make the bolt or bearing part on the opening rod for right and left stop usable, what to a design of the locking or bearing part arranged on the locking bar with two opposing legs forces between which the locking member must be able to retract. To now with a limited width of the opening bar and thus limited distance between the legs of the bolt or bearing part with a bolt member of circular cross-section To be able to move into the space between the two legs, the diameter of the circular locking member would have to be be chosen relatively small. However, this would again lead to the desired large tightening path through the interaction of the locking member and the respective leg of the locking or bearing part is determined, would be small. An out-of-round, on its locking member, which is pointed at the ends in the direction of the drive rod movement, can provide a remedy here. Such a locking link but cannot be attached directly to the connecting rod in a stiffly adjustable manner, or at least only with disadvantage. the end For this reason, the solution according to the invention is also suitable here, in which the locking member on the locking member mounting lever is attached and therefore does not have to take the adjustability into account in its shape.

The locking device according to the invention has been described above treated only in the event that the connecting rod is guided on the sash. The invention proposal can of course but also apply when a window, a door or the like. Drive rods are laid on the frame and with

But it is also possible to rotate the casement 12 around the axis of rotation Rotate BB. For this purpose, the connection between the frame 10 and the casement 12 in the tilting bearing area is at 18 solved and instead the opening rod 20, which is articulated at 22 in the area of the axis of rotation BB on the frame, with the upper sash leg 24 coupled. This coupling is carried out by a locking member 26, which with a bolt or Bearing part 28 can be brought into engagement on the opening rod 20. The opening rod 20 is at 30 with the upper one Sash leg 24 articulated and connected in a longitudinally displaceable manner. An additional arm 32 of the opening rod 20 attaches the opening rod 20 when locking this opening rod 20 with the upper sash leg 24 in the longitudinal direction of the upper Sash leg 24 fixed relative to this. A locking member 34 is used for locking when the sash frame is closed of the casement with a bolt or bearing part (not shown) on the frame 10.

The locking members 26 and 34 are not shown in FIG. 1 Driving rods displaced in the longitudinal direction of the respective sash legs by moving a swivel handle 37.

The structure of a tilt and turn window described so far is general known.

In Fig. 2 you can see a locking device according to the invention, as it is used in the tilting bearing area at 18 according to FIG. A drive rod 38 is attached to a faceplate 36 guided. When installed in a sash, the drive rod is received by a groove in the folded peripheral surface of the sash; this groove is covered by the faceplate. The faceplate is fastened with screws, which are inserted in engage the sash material and push through at 40 the faceplate and elongated holes 42 of the drive rod.

At the upper end of the drive rod 38 coupling elements 44 are attached for connecting a drive rod continuation, the with the pivot handle 37 is geared in connection. A locking member 46 is attached to the lower end of the drive rod, which is intended for engagement with a locking and bearing part 48 on the frame side. When this locking member 46 compared to the The locking and bearing part 48 assumes the position shown in FIG. 2, so the casement is in the closed position locked to the frame. When the locking member 46 is in the region of the cutout 50 of the locking and bearing part 48, so the casement 12 can be opened by rotating about the axis BB will. When the locking member 46 engages between the legs 52 of the locking and bearing part 48 on the frame side, so can the casement 12 can be brought into the tilted position, as indicated in FIG. The casement is then through the interaction of the The locking member 46 is secured against being lifted out by a safety catch 54 of the leg 52. The actual tilt bearing is formed by a flap 56 connected to the faceplate 36, which rests on a roller surface 58 of the locking and bearing part 48 runs up. The locking member 46 is, as can be seen from Fig. 4, tapered at its upper and lower ends at 60, so that it is with the edges and surfaces of the latch and bearing member 48 can be easily pulled into engagement.

The locking member 46 according to FIG. 2, as can be seen in particular from FIG is attached to the drive rod 38 by means of a pivot pin 64 in the form of a tubular rivet. The pivot pin 64 engages through an elongated hole 66 of the faceplate. The bolt mounting lever 62 rests on the outside of the faceplate and carries at a distance below the pivot pin 64, the locking member 46. At its lower end, the locking lever 62 carries on its rear side has a T-shaped rear engagement member 68, which passes through the elongated slot 66 with its middle leg and with

809882/0320

its transverse leg rests against the inside of the faceplate 36. The center leg of the T-shaped rear engaging member 68 has lateral movement play in the elongated slot 66.

An eccentric adjusting member 70 is provided to adjust the locking member mounting lever 62 relative to the drive rod 38, which at 72 is difficult to rivet to the connecting rod 38. A guide part which is concentric with the rivet pin 72 74 of the eccentric adjusting member 70 engages in the elongated hole 66 of the faceplate 36 and fulfills a guiding function for the drive rod 38 opposite the faceplate 36. An eccentric part 76 of the eccentric adjusting member 70 (eccentric opposite the rivet pin 72) engages in an elongated hole 78 of the locking member mounting lever 62. By turning the eccentric adjusting member 70 by means of a rotary tool inserted into the slot 80 leads to a pivoting of the locking member mounting lever 62 around the pivot pin 64 and thus for an adjustment of the locking member 46 perpendicular to the plane of the drawing of Fig. 2.

The central part 74 of the eccentric adjusting member 70 can be kept smaller in diameter than the width of the Long slot 66 in the faceplate 36. Unintentional turning of the eccentric adjusting member is then no longer possible fear.

The purpose of this adjustment of the locking member 46 is particularly clear from FIG. 4. The lower edge 82 of the sash overlap in this illustration has a small distance from the visible surface 84 of the window frame. the The size of this distance depends on the tilt angle of the

809882/0320

a- -

Sash 12. It is desirable that in the fully tilted Position of the distance of the edge 82 from the visible surface 84 is as small as possible to prevent rattling of the tilted position To prevent sash. Now, however, the angular position of the sash frame 12 is given for a given opening pole construction 20, 32 variable depending on the height of the sash. It is therefore necessary when varying To correct the height of the casement, the distance between the edge 82 and the visible surface 84 of the window frame 10. this

809882/0320

can be done by adjusting the locking member 46 perpendicular to the plane of the wing. When the distance between edge 82 and the visible surface 84 is small enough in the optimal case equal to zero, so it is also ensured that the locking member 46 does not over the anti-lift lug 54 can be lifted upwards, unless, after the sash 12 has been tilted inwards, but the excavation after inward tilting by the then occurring engagement of the sash in the rebate of the Frame is prevented.

The embodiment according to FIGS. 6 and 7 differs from the embodiment according to FIGS. 2 to 5 only in that the locking member support lever 162 can be pivoted by means of the pivot pin 164 in the area of the locking member 146 on the drive rod 138 is mounted and that the eccentric part 176 of the eccentric adjusting member 170 engages in a fork 178 of the locking link mounting lever 162. The eccentric adjusting member 170 is in this case provided with an Allen recess 180.

The locking member 34 intended to interact with a striker plate of the window frame can be opposite to the drive rod and the faceplate can be arranged exactly as described with reference to FIGS. 2 to 7.

In FIG. 8, the locking member 26 can be seen in engagement with one leg 28a of the one attached to the opening rod 20 Lock and bearing part 28. The adjustability of the locking member 26 perpendicular to the longitudinal direction of the opening rod 20 is the same achieved as described in connection with FIGS. By adjusting the locking member 26 perpendicular to the The longitudinal direction of the opening rod 20 can be achieved that for the rotating operation of the sash, the opening rod, the is shown in Fig. 8 at a small distance a from the rollover of the sash, pressed tightly against this rollover is, so that the opening rod 20 relative to the

809882/0320

upper leg of the sash is fixed immovable. This is desirable to avoid wobbling of the sash to prevent the opening rod 20 when the sash frame is in the rotating opening.

It should be added that, as can be seen from FIG. 1, the essentials Fitting parts, namely faceplate rails, connecting rods, opening rods and additional links in the rebate of the sash and in the rebate of the frame are concealed. Blind frames and blind sashes can be made of wood or plastic or aluminum be.
