EP0119433A2 - Fitting for a wing of a window, door or the like, which is at least tiltable and movable from one plane to a second parallel plane - Google Patents

Abstract

To an at least tiltable and parallel-adjustable wing of a window or a door or the like. To secure in the tilt position against unintentional or unwanted parallel parking, there is a locking device (29) at the lower wing end between the wing and the frame spar, which consists of a locking element (30) and a locking member (31). A lost motion distance preferably prevents the latching element (31) from being displaced when the fitting changes from the locking position into the tilting position. If the fitting is switched from the tilted position to the parallel storage position, this leads to a movement of the latching element (31) in the direction of the arrow (35) and thus to an unlocking of the locking device (29). Now the wing can also be moved towards the interior of the room at its lower end, i. H. can be connected in parallel. If you let go of the twist grip (17) in the parallel parking position of the fitting or a three-position gear or the olive (8), a return spring (36), and preferably an additional return spring (45), causes the fitting to be reset. A run-up slope (51) of the latching member (30) in connection with the latching extension (41) of the latching member (31) ensures that the locking device (29) automatically goes back into the locked position when the lower wing end is folded back.

Description

The invention relates to a fitting for an at least tiltable and parallel-adjustable wing of a window, a door or the like. With a locking linkage of the wing which can be operated by means of an actuating member and which extends from the actuating member at least along the lower end of the wing. In some constructions, parallel-adjustable sashes are first placed in a tilted position and then also extended at their lower end, which then makes them parallel to the fe take the most frame. In this parallel position, they can be moved along a second fixed or movable wing, a wall or the like. In the tilted position, such wings are relatively burglar-proof, in particular if the wing is tilted only slightly, like a night vent.

It is different, however, if you can bring this tilted wing into the parallel storage position, and then it can be moved to the side, which opens a fairly large entry opening.

The object of the invention consequently is to improve a fitting of the type mentioned such that the Flü- ^g el is secured in the tilted position against undesired parallel parking.

To achieve this object it is proposed according to the invention that the fitting is designed according to the preamble of claim 1 in accordance with the characterizing part of this claim. If you move the wing of this window or door from the particularly locked closed position to the tilt position, the parallel storage position can only be brought about subsequently if the locking device on the lower wing end is released beforehand by hand via the locking linkage. The wing can then be parked in parallel and, if necessary, pushed to the side be. Releasing the locking device does not necessarily lead to the transition to the parallel storage position. If the latter is not achieved automatically or quasi-automatically, it can be brought about by hand or by another special configuration of the fitting after the locking device has been released. The locking rod is acted on in a known manner via a handle, preferably a rotatable actuating handle. The latter, if available, can be used to release a lock against the fixed frame and, if the fitting so provides, also bring about the tilting position. In the other case, the tilt position is reached after releasing the lock, for example by simply pulling on the actuating member.

A further development of the invention is characterized by at least one latching element fastened to the lower cross member or the like. Of the fixed frame or the like engages behind a latching edge of the latching element with a latching attachment. The latch member must be assigned to the latching element such that the necessity for disengagement di e ^g displacement movement of the locking linkage is in the correct assignment to possibly upstream displacement movements of the shutter linkage. So if the locking linkage moves from right to left, for example during the transition from the closed position to the tilting position, then the disengagement must also movement from right to left so that the movement of the drive rod for the tilting movement can be followed by a disengaging movement in the same direction.

A preferred embodiment of the invention provides that the latching element can be displaced into the disengaged position against the resistance of a return spring, the return spring, in particular a helical compression spring, between the latching member and a wing-fixed edge, surface or the like. is inserted. The drive rod thus displaces the latching member in the disengaging direction, with the return spring tensioning or tensioning at the same time. At the end of this stroke of the drive rod, the maximum tension of the return spring and, at the same time, possibly a little earlier, the release position is reached. If you then release the drive rod, the return spring presses the drive rod and all parts coupled with it, in particular the latching element, back into the starting position. If you want to return the wing afterwards from the parallel storage position to the tilted position, you either have to design the locking device so that this return movement is easily possible, or else bring the drive rod back into a suitable displacement position for disengagement. Particularly when the locking device is designed appropriately, this configuration has the advantage that the tilted wing is automatically locked again when the wing placed in parallel is folded back into the tilted position.

Another variant of the invention provides that the latching member penetrates an opening in a faceplate of the locking rod, the length of which, viewed in the longitudinal direction of the faceplate, corresponds approximately to the length of the latching member in this area plus the maximum displacement distance of the latching member, the return spring between the latching member and a transverse edge of the opening is inserted. Here, the breakthrough of the faceplate, which is anyway necessary for the passage of the locking member coupled or connectable locking member, can also be used to support the return spring.

A further embodiment of the invention is characterized in that a run-on slope for the latching attachment of the latching member is attached to the latching element, the run-up slope and the latching attachment interacting when the wing is pivoted from the parallel parking position into the tilting position. In this respect, it is the functional design of the locking device, which has already been indicated above and which automatically comes into operation again when the wing placed in parallel is returned to the tilted position.

A very advantageous development of the invention results from claim 7, and it enables the right and left stop of the locking device. The latching member is therefore symmetrical at its end facing the latching element due to two Longitudinal center axis arranged locking lugs designed fork-shaped. The latching element has essentially a trapezoidal shape with a latching edge formed on both ends.

Another preferred embodiment of the invention is characterized in that the drive rod is coupled to the locking member part of a corner drive or with its horizontal leg or an elongated drive rod, with the vertical leg of the corner drive, or a vertical drive rod coupled to it, the actuating member of the fitting is in drive connection. If the drive rod and the latching member are part of a corner deflection, it should be understood that the latching member is attached to the displaceable force deflection means of the corner deflection or can be coupled.

In a further embodiment of the invention provides that the actuating member with the drive rod via a window etriehe ^g or is driveably connected to a transmission Olive and a drive rod fixed cam, being provided the transmission as a three-position gearing with the switching positions "locking", "tilt", "parallel parking" . A "three-position gearbox" is understood here to mean a gearbox which, starting from a first position, can be brought into two further positions in succession, the two "shifting movements" being able to be of different sizes and preferably being so. The three "show positions" are also shown in an analogous manner if a gear olive is used instead of the three-position gear. Leg transfer of the three-position gear or the like from the locking into the tilting position usually causes the actuating element to rotate through 90 °. If it is subsequently to be switched over to the parallel storage position, the actuating member is rotated again in the same direction of rotation, preferably by an additional approximately 20 °. It is irrelevant whether the (first) 90 ° rotation only reaches a ready-to-tilt position from which the sash is brought into the tilted position by hand, or whether the fitting is due to special training, particularly in the area of the opening device or - devices on the upper wing end, this tilting automatically causes. The same applies to the parallel parking area. You can also bring it automatically via the fitting, or, if only a parallel parking standby position can be reached via the pedals, from which the sash does not automatically go to the parallel parking position, you can simply pull it, especially with the help of the control handle towards the interior of the room until it is parallel to the fixed frame. In the case of automatic transfer to the parallel storage position, however, the angle of rotation must be substantially greater than 20 °, for example 90 °.

Another advantageous embodiment of the invention is that between the closing drive rod and a wing-side fixed stop in the tilted position of the fitting, an additional return spring that can be tensioned when the drive rod is moved into the parallel parking position is connected. It supports the return spring on the lower wing end in a restoring sense. It makes sense if the actuating fitting extends over at least the lower and the closing end of the wing stretches and this applies even more if there are drive rods on the upper or even on all four uprights of the wing. In the latter case, additional return springs can be attached to the other corner drives.

A special variant of this Peschlags results from claim 11. During the (first) quarter turn of the actuating member nothing changes in the tension of the additional return spring, that is, if it is not biased, it remains in the transition from the closed position to the tilt position or Ready to tilt ready. Subsequently, however, the driver coupled to the drive rod on the locking side hits the end of the additional return spring assigned to it and takes this end with a constant increase in the restoring force. At the end of the second rotary movement, the maximum restoring force of both this additional restoring spring and the restoring spring at the lower wing end is reached. Both together move the drive rod and all parts coupled with it back to the starting position as soon as the actuator is released. “Starting position” is understood here to mean the position that is reached at the end of the first free movement, that is to say the tilting or tilting ready position. The two support members for the additional return spring are advantageously located on the closing-side cuff rail part belonging to the corner deflection. In this case, the tiller is also part of this corner deflection.

A very advantageous embodiment of the invention consists in that the drive rod is coupled to the latching member to form a lost motion path via a pin-Schiits connection, the lost motion distance corresponding to the displacement distance of the drive rod in the transition from the locking position to a tilting or tilting readiness position. This design enables the sensible use of a three-position gearbox or a corresponding gearbox with olive, the switchover from the tilting position to the parallel storage position being preceded by a switchover process with which a lock can be released and the tilting or tilting ready position can be brought about. The same applies of course when the tilted wing is returned to the closed position with subsequent locking.

In a frame 1, the wing 2 of a door, but it could also be the wing of a window, can be tilted (FIG. 2) and stored in parallel (FIG. 3). In the parallel position, it can be pushed in front of a fixed field 3, which can be another glazed wing, for example. It is also easily conceivable that this further wing is, for example, a rotating or reversible wing or a wing that can be moved in another way. In any case, the wing 2 is preferably tiltably and slidably supported on a running rail 6 by two carriages 4 and 5, wherein the running rail can be firmly connected to the lower crossbeam 7 of the frame 1. The wing is equipped with a "three-position gear" in the sense of the above explanation or, preferably, with a gear olive 8 and a driver which is attached to a vertical drive rod 9. The drive rod 9 is in drive connection with a horizontal drive rod 11 via a lower corner drive 10. A fine upper closing corner drive 12 creates the connection to an upper horizontal drive rod 13, with which two scissors 14 or the like can be operated. In the exemplary embodiment, two further corner deflections are also provided which are connected to the drive via an additional vertical drive rod 15.

The olive 8, which can be coupled to the driver 16, has a turning handle 17 which, when the wing 2 is closed and locked, points upwards according to the dash-dotted illustration 17a. Not only the driver 16, but at least one locking bolt 18 is firmly connected to the drive rod 9, both, or their fastening elements, penetrating longitudinal slots 19 and 20 of a faceplate 21. The one or more locking bolts interact in a known manner with locking surfaces and the like. The frame 1. The closing-side faceplate 21 is connected to an angular faceplate 22 of the corner deflection 10 or connects to the vertical leg of this faceplate. In addition, the vertical drive rod 9 is coupled via an adjustable toothed coupling 23, 24 to the corner deflection means 25 of the corner deflection 10 or to the lower section 9a of the drive rod connected to the corner deflection means, which also carries a further locking bolt 26.

The unlocking of the closed wing is achieved by turning the rotary handle 17 in the direction of arrow 27 from the position 17a drawn with dash-dotted lines to the position 17 drawn with solid lines. This can be connected to actuating the stay scissors 14, or at least lead to a release position of these scissors so that you can bring the wing into the tilt position shown in Fig. 2 by pulling the handle 17.

However, the parallel storage position according to FIG. 3 is not readily possible because the lower wing end is initially held in place by a locking device 29 (FIG. 8). The locking device 29 includes a locking element 30 which is fastened to the lower frame spar. Corresponding fastening screws 32 can be seen in FIG. 11. The locking device also includes a locking member 31, which in the exemplary embodiment is slidably mounted on the faceplate 33 of the corner deflection 10. A corresponding longitudinal guide 34 is formed by punching out this faceplate.

8 to 10 it can be seen that the locking member 31 can only be displaced in the direction of arrow 35 against the resistance of a return spring 36, which is preferably a helical compression spring. The opening 34 of the faceplate 33, which serves as a longitudinal guide, has at its one end, on the left in FIG. 8, a spike-like extension 37, on which the left end of the spring is attached. The right end of the spring protrudes into a comparatively long bore 38 of the locking member 31, so that the spring is guided well overall.

The exemplary embodiment is the drive rod 28 with the catches member 31 is not rigidly coupled, rather a lost path is interposed. For this purpose, the drive rod 28 has an elongated slot-shaped slot 39, into which a pin 40 of the locking member 31 projects. When the wing is locked (FIG. 8), the pin 40 is assigned to the one end region - in the exemplary embodiment the left end region - of the slot 39. Thus, when operating the fitting from position 17a to position 17, the drive rod 28 is transferred from the position shown in FIG. 8 to the position shown in FIG. 9, the slot 39 moves relative to the pin 40, which is the Backlash distance corresponds. At the end of the unlocking and, if necessary, gear-controlled opening of the wing into the tilting position, the right end of the slot 39 comes into contact with the pin 40 or at least in the vicinity thereof. With a further stroke of the drive rod 28 in the direction of arrow 35, which is caused by turning the rotary handle 17 further in the arrow direction 27 by preferably about 20 °, at the end of this second rotary movement the free end of the rotary handle 17 pointing obliquely downward in the manner of a door handle -this second rotary movement is symbolized by the representation 17b-, the drive rod 28 takes the pin 40 in the direction of arrow 35, and thus the latching element 31 is also displaced in this direction against the resistance of the return spring 36.

From FIG. 11 the dash-dotted lines show the assignment of latching element 31 and latching element 30 shown in FIGS. 8 and 9. It can be seen that a latching extension 41 of the latching member 31 engages behind a locking edge 42 of the locking element 30. A second latching attachment 4la, a second latching edge 42a enable the locking device 29 to be left and right-hand stop. The latching member 31 is designed symmetrically to the longitudinal central axis 43 and the latching element 30 to the axis 44. In FIG. 11, the position according to FIGS. 8 and 9 is shown with dash-dotted lines, while the position according to FIG. 10 is indicated with solid lines. In this disengaged position of the locking device 29, shown in FIG. 11 with solid lines, movement is possible with respect to the longitudinal center axis 43, ie with respect to the longitudinal axis of the lower wing spar, so that the latter can be transferred to the parallel parking position shown in FIG. 3. This happens, for example, in that the sash automatically moves into the parallel position due to the effect of its own weight in connection with particularly smooth-running bearings of its extension arms. At least one can expect or achieve support in this regard.

if you then release the twist grip 17, the return spring 36 causes the locking member 31 to be pushed back and the latter in turn takes the drive rod 28 against the arrow 35. The Eandgriff accordingly moves backwards in the direction of the arrow 27 in the direction of the position drawn in with fixed lines 17.

because the force of the spring 31, especially in the case of circumferential drive rods, such as are provided in the exemplary embodiment, may not be entirely sufficient, or the provision may only be made is slow, an additional return spring 45 is provided on the vertical leg of the corner deflection 10, which supports this reset movement and the disengagement of the locking device is also tensioned. Additional return springs can be installed if necessary.

The additional return spring 45 is inserted between two support members 46 and 47 connected to the closing face plate 22. The lower support member 45 is comparatively flat and has a mandrel 48 for insertion into the lower end of the spring. On the vertical lower section 9a of the drive rod 9, which is expediently U-shaped or double-walled, there are two drivers 49. They can be moved past the lower support member 46 laterally at the front and rear (in FIGS. 5 to 7).

When the wing 2 is closed and locked, the drivers 49 are in the lower end position shown in FIG. 5. After a 90 ° rotation of the rotary handle 17, the drivers 49 have moved upward in the direction of arrow 15, so that they now (FIG. 6), approximately at the lower end of the additional return spring 45, in particular bear against it. The fitting has reached the "tilt position", in which the upper wing end is either raised or in a tilt ready position.

If you now turn the handle 17 in the direction of arrow 27 further down to position 17b, the Witrehrer 49 have the lower spring end of the support member 46, the additional return spring 45, as well as the return spring 36, is tensioned. In the parallel parking position of the fitting, the position according to FIG. 7 is reached, which corresponds to the position according to FIG. 10. Accordingly, the additional return spring 45 supports the return of the peschlag in the tilted position. The locking member 31 is then in a displacement position which corresponds to that with dash-dotted lines in FIG. 11, but due to its parallel offset due to the parallel position of the wing 2, it is no longer locked with the locking element 30. The two and possibly additional return springs cause the drive rods and all parts coupled to them to be reset, but the wing remains in the parallel storage position because the opening of the lower wing end is not controlled by the drive rods, but due to a torque from its own weight and / or is effected by hand by pulling the rotary handle 17 towards the interior of the room.

If one now transfers the lower wing end from the position shown in FIG. 3 into the position according to FIG. 2, the latching projection 41 of the latching member 31 runs up on a run-up slope 51 of the latching element 30. When the latching projection 41 slides along the run-up slope 51, the return spring 36 is briefly tensioned again until the latching has ended. Thus, the sash is automatically secured again when moving from the parallel storage position to the tilt position. It remains to be added that the screws 32 are covered by the lower wing spar so that the locking element 30 cannot be willfully removed.
