Abstract

The handle (3) turns on a pivot axle (4) at right angles to the casement or leaf plane and fits into a fitment (7) driving the locking gudgeon. The fitment moves along a groove (9) on the casement or leaf. The handle and fitment are connected by a deflector gear (12) converting the turning movement of the handle into the lengthwise movement of the fitment. A swivel lever (16) is connected to the pivot axle, and a thrust lever (17) is joined to the fitment.

Description

The invention relates to an openable window sash / Door leaf according to the preamble of the main claim. Such window sash / door sash are known from GB-A-20 72 740 and GB-A-21 50 972. These window sashes / door sashes face outwards open. Accordingly, the handles to the glass side shifted there. From DE-U-94 15 966 is a lock gear known with which the rotational movement of the handle over a Cardan joint is transferred to a pinion.

Such window sash is a so-called turn-tilt window well known. With such window sashes generated a rotary movement via the handle, which in corresponding Locking or opening movement of the fitting implemented becomes.

It should be expressly pointed out that the Invention is not limited to such tilt-and-turn windows, but e.g. also double-leaf sash windows in a turn-turn version includes.

The object of the invention is the known deflection gear to improve so that with simple assembly using as few transmission links as possible, also the bridging long distances is possible.

This task is performed with the window sash / door sash mentioned at the beginning solved by the features of claim 1. The swivel lever extends practically parallel to the sash level towards the hardware groove. The thrust lever extends practically perpendicular to the wing plane to the inside of the room. The common area of intervention is hidden from view.

The design of the pivot lever as is essential Gear. This not only simplifies assembly but also lets also an unlimited swivel range too. With this configuration it offers itself, the toothing of the swivel lever in a rack-like design that runs longitudinally on the window sash / door wing Let the drive rod engage. To this The rotational movement of the gear-type pivot lever becomes with unlimited swivel range in a linear motion implemented. By simply coupling the push lever with the longitudinally driven drive rod one becomes geared flawless connection that creates no other elements needs more.

To do this, an opening is formed on the push lever the drive rod has a pin corresponding to the opening, the pin engages in the opening can be done in the simplest way Way realized the required bi-directional drive become.

In particular, the opening can also be made fork-shaped, so that the pin is simple with simplified assembly is inserted into the fork.

The invention proves to be particularly advantageous for the requirement for historic old buildings where the axis of rotation the handle should sit on the blow bar. For this are so far no solutions in the plastic window area have become known. The transmission bridging between the handle and Fogging is known to be prevented by the sash profile. Solutions have been sought, the casement profile to mill accordingly to at the blow bar arranged handles still drive the fitting can. However, these attempts have not proven effective since suitable reversing gearboxes were not available.

On the other hand, this is how the reversing gear is built small that it is complete even in a cavity of the blow bar Takes place. The end area is covered of the swivel lever, as desired per se, the casement. On the other hand, the thrust lever is geared to the end area of being able to couple the pivoting lever is in this case suggested that the sash profile in the swept Milling area through a longitudinal slot and the thrust lever through the milled slot with the end area of the Connect lever. A simple rigid connection between the thrust lever and the fitting results from the fact that the Push lever at its end connected to the fitting in a T-shape or Y-shaped or the like. is spread and in the area of the spread ends with two in the longitudinal direction of the fitting spaced fasteners with the Fitting is connected.

Unless otherwise stated below, the following description for all figures.

First of all, Fig. 2 shows a window sash / door sash according to this invention in cross section. Such window sash / door sash consists of a wing 1 with a handle 3. In the present case, this wing is part of a double-leaf window and has a corresponding one Window sash 2 without handle.

With regard to further details, the state of the Technology referred.

The following is for the term window sash / door sash the term wing is also used. As is well known such a handle 3 around a perpendicular to the wing plane 6 horizontal axis of rotation 4 rotatably mounted on the casement. there is the handle 3 with a locking pin 8 driving Fitting 7 so geared together that the Rotational movement 10 of the handle in longitudinal movement 11 of the fitting is implemented. For this purpose, the fitting 7 in one fitting groove 9 running along the casement on the casement flexibly guided. The fitting is guided so flexibly that the locking pin 8 with respect to a fixed locking plate 27 can extend or retract.

With regard to the deflection gear 12, there is now the special feature that that the axis of rotation 4 of the handle 3 the longitudinal direction 14 of the fitting groove 9 crosses at a distance of 13. The distance 13 is so large that the axis of rotation 4 outside the outermost boundary plane 15 of the casement runs. The an essential problem with this invention is therefore design the reversing gear so that the bearing of the axis of rotation 4 principally takes place outside the casement. The In any case, the axis of rotation is not supported on the casement, while the necessary for the storage of the axis of rotation 4 stationary parts, however, are definitely attached to the casement could be.

On the axis of rotation 4 sits a non-rotatably connected Swivel lever 16, the back and forth movement by means of handle 3 can be moved. The push lever 17 is rigidly connected to the fitting 7 for the locking pin 8. The push lever 17 therefore only executes the longitudinal movement 11 of the fitting 7, while the pivot lever 16, the rotary movement of the handle.

First to Fig.1: The plane of movement of the swivel lever lies in the drawing plane (= wing plane). The plane of movement the thrust lever 17 is perpendicular to this.

A pair of 2-way drivers is used for gear coupling. which are realized here by a fork-shaped Opening in which a corresponding pin of the Push lever 17 engages.

In all cases it can be assumed that both for the The following applies to the pivot lever 16 for the push lever 17:

Swivel lever 16 and push lever 17 are geared coupled via a 2-direction driver. Both 2-way drivers are constantly in mutual engagement.

With the help of this design, it becomes possible to set the axis of rotation 4 with respect to the thrust plane, that is, the plane of movement of the push lever 17 - to displace a distance 13, which even outside the boundary plane 15 of the casement ends to be both reliable and cant-free Ensure the rotary drive for the locking pin 8.

In addition to this, Figures 2 to 4 show that according to the invention the pivot lever 16 is designed as a gear 20. The gear 20 is rotatably connected to the axis of rotation 4. The axis of rotation 4 is formed by a square 29, which is connected to the handle 3 is. The gear 20 engages with the teeth 31 in corresponding Recesses 32 of a longitudinal rack 21. The rack 21 is within a housing 33 in Longitudinally arranged, the housing is as common gear housing designed for the reversing gear.

This measure ensures that the rotary movement the handle 3 immediately in a longitudinal movement is implemented. The rack-like drive rod 21 must therefore only be coupled with the thrust lever 17. For this purpose it is provided that the push lever 17 with a 2-direction driver 19 in a corresponding 2-direction driver 18 engages the drive rod 21 with the Swivel lever 16 is coupled.

In the case of Figure 1, the 2-direction driver 19 of the Push lever 17 realized by a pin during the 2-direction driver 18 the drive rod 21 from a fork is realized.

In all of the exemplary embodiments in FIGS. 2-4, the relationships are vice versa. The pin 18 is rigid with the Rack 21 connected. As additionally shown in Fig. 4, the push lever 17 with its fork-shaped opening can easily be inserted in the longitudinal direction on the pin 18. This serves to facilitate the assembly of the reversing gear.

As can be seen in Figure 2, all that is required is an opening 24 in the casement through which the push lever 17 is inserted becomes. The push lever 17 projects with its fork-shaped Opening 19 at the free end of the front plane of the casement to the extent that it now led from the outside Deflection gear, consisting of swivel lever 16 and rack 21 can be inserted into the fork-shaped opening. there encompasses the fork-shaped in the embodiment shown Opening 19 of the push lever 17 is rigid with the rack 21st connected pin 18 and the reversing gear can be attached. For this purpose, the blow bar 22 has a cavity 23, which consists of the entire reversing gear Swivel lever 16 and rack 21, picks up. Then you can connect the blow bar 22 firmly to the casement 5.

This gives the particular advantage that the handle 3 can sit in the middle of the blow bar 22. In particular for the renovation of old building windows, in particular This version offers double-leaf old building windows Benefits. According to this invention, since the end portion of the Swing lever 16 can sweep the sash 5 and nevertheless, the assembly of the handle 3 with axis of rotation 4 wide outside the outermost boundary plane 15 of the casement Another advantage of the invention results. For gear coupling the pivot lever 16 with the Push lever 17 only has to have a longitudinal slot 24 be milled in the casement 5, through which the Push lever 17 can then be inserted through.

The resulting longitudinal slot is, however, by the Blow bar 22 reliably covered and therefore remains invisible. An optimal area of engagement between the pivot lever 16 and push lever 17 is guaranteed in any case if the movement level of the swivel lever (= swivel plane) and the plane of movement of the thrust lever (= thrust plane) Cut perpendicular to each other in the area of engagement.

In addition, Figure 4 shows that the push lever 17 a can be a separate component independent of the fitting 7. The Push lever 17 has on to be connected to the fitting 7 End of a transverse extension. The floor plan of the Push lever 17 therefore corresponds essentially to a T. The transverse leg of the thrust lever 17 points to its two end areas each connecting points 25 with the fitting 7 on. The connection points are at a distance 26 seen in the longitudinal direction of the fitting 7 from each other and therefore able to attack those at the free end of the thrust lever Intercept lateral forces torque.
