Description

The invention relates to a window handle for a window with electromechanical functional elements.

Windows with electromechanical functional elements are known per se.

Thus, it is known to tilt windows, which are tiltable about a horizontal (usually lower) axis of rotation, by means of electric motor drives to open and close. The switching of the drives takes place via arranged on the window frame or the wing switch.

This operation of windows is indeed well thought out, but unusual. In addition, the assembly is unusual for the window maker and may require u.U. Basic electrical knowledge.

The invention therefore has the object to remedy this problem in a simple manner and to provide a window handle, which should preferably be particularly easy to assemble and allows a particularly simple and easy to understand operation and operation of windows with electromechanical functional elements.

The invention solves this problem by the subject matter of claim 1.

Advantageous embodiments can be found in the dependent claims.

The invention provides a window handle for a window, in particular for a tilt and turn window, with electrically switchable functional elements, which is designed as a handle with a handle for manually moving, in particular turning, a wing of the window and at least one arranged on the handle, manually operable from the outside, comprising electrical switching element.

Preferably, the handle has a rotatably mounted on a handle rosette handle neck, wherein the handle is aligned at an angle to the handle neck.

In this case, no movable connection between the handle and mechanical transmission elements of the wing of the window is provided. Rather, the handle preferably has on the handle neck on the outside a pivot bearing, which is completed by a handle rosette.

The invention provides by the subject matter of claim 1 a preferably pre-assembled window handle in the manner of a handle, which is at least - and in a preferred embodiment even exclusively - designed for manual movement of the wing in a rotational position with respect to a manual operation of the window and combines them directly and directly with an externally accessible on the handle, manually operable switching element, which is preferably used in the installed position for actuating an electric motor drive for moving the wing in and out of a tilted position. Thus, the operation of a conventional window is similar and thus simplified. In addition, the handle with the switch can be designed as an optical unit responsive. Separate switching elements that interfere with the view of the window or change undesirable are no longer necessary.

Since handle and switching element can be prefabricated as a unit, also the installation on the window is simplified.

The handle is accordingly preferably manufactured as a preassembled unit, which arranges the window manufacturer simply by plugging on the wing, according to a particularly preferred - even independently viewable variant of the invention - elements of an electrical connector between the wing and handle interlock, allowing a particularly simple installation ,

Preferably by means of screws then carried out the final assembly on the wing. Movable mechanical drive elements between the wing and handle are not provided. Almost all functional elements on the window are rather provided with electromotive or electromagnetic drives, which are the externally accessible switching element on the handle or Grifflials and possibly other switching elements are controlled.

In turn / tilt windows with electric motor drives, it has been found that while the realization of an electric motor drive for moving the wing in a tilted position makes sense, but not the realization of a drive for moving the wing in its rotational position, as in many cases - eg in office buildings - although the tilted position is used regularly for ventilation, but not the rotational position. This is less commonly used, e.g. for cleaning the windowpane.

For this reason, a turn / tilt window was created, the wing of which is manually movable into its rotational position and which has an electric motor drive for moving the wing in and out of its tilted position, for example with an electric motor which acts a rigid chain, the wing when opening the frame continues. The switching handle according to the invention allows e.g. the simple operation and handling of such a window, wherein the manual opening and closing function is combined in the manner of a manual handle with the function of an electrical switch advantageously in several ways.

The handle is preferably pivotable in only two different positions, namely preferably in the downwardly facing closure position and in the horizontal position pivoted by 90 ° for the rotational opening of the window.

The tilting opening and the closing take place via an electromotive drive, which is actuated by means of the switching device, which is preferably arranged in the handle neck.

Another particular advantage to mention is given by variants of the dependent claims simple interchangeability of the electrical circuit in the window handle and / or the switching units.

The invention also provides a window handle for a window, in particular for a tilt and turn window, with electrically switchable functional elements, characterized by a design as a handle with a handle for manually moving, in particular turning, a wing of the window, and at least one arranged in the handle rocker switch for switching the functional elements, which allows in a simple way by the handle through the actuation of switching elements.

a sectional view of a handle on a (metal) profile of a window sash.

Fig. 1 shows a handle 1 for a tilt and turn window, which is used for manually opening and closing a wing of a turn / tilt window (the airfoil 30 is shown in Fig. 5) in and out of a rotational position about a vertical axis of rotation and at least for switching a electromotive drive of the turn / tilt window is designed to open and close the wing in and out of a tilted position.

FIG. 1 shows the control handle 1 with a handle neck 2 and a handle (section) 8 which is oriented perpendicular thereto.

The handle neck 2 is mounted by means of corresponding bearing elements in the Schaltgriffrosette 5, which is attached to a window sash relative to this rotatably. In this case, the Schaltgriff rosette 5 is e.g. attached to the wing profile by screws (not visible here) (see FIG. 5)

In addition, an electrical connector between the wing and the handle is realized.

There is no connection between the sash and the handle via movable gear elements.

Thus, although the handle can be used to move the wing about its vertical axis of rotation, but not for manual operation of fittings of the window. Rather, these are realized by electromotive or electromagnetic functional elements, such as by electromotive movable pins on the wing, which are e.g. interact with corresponding elements like a trap on the frame ..

In the handle 2 of the switching handle 3, a housing insert 3 is introduced, on which a rocker switch 4 is located (see also Fig. 5).

The rocker switch 4 switches according to the applied symbols 31 (see FIG. 1: open and closed) electric motor drives and other associated functional elements such as a rotary and / or tilt bearings in their corresponding functional position to the sash in the tilted position or in the closed position to move. In this case, the handle 8 remains stationary relative to the Schaltgriffrosette 5 immobile in the closed position or the starting position.

To open and close the window sash in his and out of its tilting position is used exclusively from the outside manually accessible switching element, which is designed here inexpensive and compact on the nature of the rocker button 4

From the contact surface 29 of the Schaltgriffrosette 5 protrude on the side facing the wing, a power strip 6 (or alternatively a female connector) as well as two centering 7 out.

The connector strip 6 contacted when plugging on the wing a corresponding female connector 7 (or connector strip) on the wing.

It is essential that an electrical connector between the handle 8 and its handle neck and the wing profile 30 is realized, so that no cables in the area of the handle are to be connected during installation more.

The two centering lugs 7 cooperate with corresponding recesses on the sash profile (not visible here, the sash profile is visible in FIG.

For assembly, only the preassembled control handle 1 with its centering lugs 7 must be meshed with one another in the corresponding recesses in the wing, it being important to ensure that the connector strip 6 and the female connector interlock. Then, optionally, an (ideally) preassembled screw (s) of the switching handle can be screwed into the sash. Locking rods or the like are not mechanically connected to the handle. The assembly of the preassembled unit "handle" is so simple. It is also conceivable to attach the corresponding connector part (female connector or connector strip) in the wing with a short cable to the controller in the wing (not shown here) and after mounting the handle of this cable with his connector part to the corresponding connector part to the handle.

In addition, the switching handle is surprisingly simple with only a few mechanically moving parts and circuit elements, although it has a variety of switching elements and functions and also the possibility for manual rotation opening of the window in itself.

Figure 2 shows an explosive composition of the control handle, in which the functional elements are visible, which are essentially decisive for the pivot bearing and the electrical switching functions.

The handle 2 passes axially through a recess (bore 9), which receives a housing insert 3 of the rocker switch 4 and facing in the rosette area a bearing insert 10th

The bearing insert 10 has an annular flange 11, on which the Schaltgriffrosette 5 is supported and presses the bearing thus formed on the bearing plate 12.

Below the flange 11 of the bearing insert 10 is an annular shoulder 13 on which a bearing plate 14 is placed, the opposite resilient locking cam 15 which engage in corresponding recesses 16 of the Schaltgriff rosette.

This bearing plate 14 is located between the flange 11 and the bearing plate 12 in the assembled state and ensures a wear-free operation of this handle bearing.

In a recess 18 of the bearing plate 12, a circuit board 17 is further used, wherein resilient locking tongues 19 lock the circuit board 17 in the recess.

On the front side of the printed circuit board, two push-button switches 20, 21 are arranged next to one another, at least one light-emitting diode 22 and at least one (micro) switch 23.

On the back of the circuit board 17, the connector strip 6 is arranged, which passes through a passage in the bottom of the bearing plate 12.

FIG. 3 shows a view from the underside of the handle mounting without the bearing plate 12.

Good to see here is the Schaltgriffrosette 5, which is formed approximately oval in the present case. Opposite opposite are the centering lugs 7 for screw-fastening of the handle.

Within the Schaltgriff rosette the locking recesses 16 can be seen, in which engage the locking cam 15 of the bearing plate 14. The bearing plate 14 rotatably encloses the bearing insert 10, in turn, the housing insert of the rocker switch is located.

In the rocker switch insert, the two switch plungers 24 and 25 are arranged, which are arranged like a segment, so that they ensure contact with the two push-buttons 20 and 21 even at 90 ° pivoting of the handle.

The bearing insert 10 has on its front edge surface on a cam recess 26 in which can einliegen unpressed in the closed position of the switching cam of the microswitch 23. When pivoting the handle from the closed position to the rotational position of the switching cam of the microswitch 23 runs against or on the control cam 26 so that the switching cam is pressed and thus the unlocking pulse for the rotational position is forwarded to the control unit or the electromechanical locks for the rotational position ,

FIG. 4 shows the bearing plate 12 with the printed circuit board 17 inserted, which is to be mounted in an appropriate manner via an index pin 21.

The bearing plate 12 is mounted on the surface of the sash together with the transmission handle and can be replaced in the simplest case in case of service.

Figure 5 shows a longitudinal section through the handle neck 2, in which the housing insert of the switching rocker is located. This housing insert 3 is made of a light-conducting transparent plastic, such as. As acrylic, among other things, and has, inter alia, the task to guide the imitated by the LEDs 22 light rocker switch border 28. For this purpose, the different colors of the LEDs for visual identification of the switching element are available.

The rocker button 4 is mounted in a further insert within the housing insert and guides the switch plungers 24 and 25, which in turn act on the push-button 20 and 21.

Figure 5 shows the mounting of the control handle on the sash profile, which can be seen that the connector strip 6 projects into the rebate of the window and there can be easily and reliably connected to the plug of the controller. The corresponding female connector is not shown here.

The handle designed in this way is very compact and extremely easy to service.

To determine the entire control handle a punched-out is made in the attack of the sash profile, which serves for carrying out the plug insertion guide on the one hand and on the other hand has two centering holes, which serve to accommodate the centering, which are arranged on the underside of the handle rosette protruding.

The determination is made in such a way that two screws are screwed into threaded holes in the handle escutcheon, which are located centrally in the centering of the rebate of the window sash.

The handle bearing has in its interior an elastic locking element, which clearly positioned the two locking positions of the handle and on the other hand clearly limits the pivoting range of 90 ° from the shutter to the rotational position.

The callipers are arranged on the handle surface in the area of the handle neck.

The electrical switching elements and the handle bearing are space-saving and compact arranged in the handle rosette and separately einfachst as a circuit unit with the circuit board 17 completely interchangeable.
