Description

The present invention relates to a window or door leaf with a glass element, which comprises at least two glass panes held together by a spacer to form a disc space, and a fitting for actuating a window or door closure.

The space between the panes is used in such multiple glazing in particular the thermal insulation. For common windows or doors, the fitting is attached to a frame of the wing. In particular, the fitting can be arranged partially or completely in a fitting groove of the casement profile. Depending on the design of the window or the door of the fitting serves different purposes such as the bearing of the wing on a frame and the adjustment of the wing in a rotational, tilting or displacement position. Under a wing can also be understood an element of a fixed glazing, which is used for example by means of a snap fitting during assembly in a corresponding opening, such as a window frame.

The customers of windows or doors are becoming more and more demanding in terms of their visual design and wish, for example, large-scale glass wings with the most inconspicuous casement. However, the sash can not be made arbitrarily narrow because otherwise there is not enough space for the fitting of the fitting.

The DE 197 33 38 A1 discloses a frameless glass wing with two panes, a spacer and an integrally formed with this edge termination element.

The DE 198 16 735 A1 discloses a turn-tilt fitting with a spacer made of plastic or aluminum, which has fitting receptacles.

In the DE 199 30 831 A1 discloses a frameless glass wing for a window or door comprising two sheets of glass, a spacer therebetween and an edge termination. In the edge termination element a receiving groove is formed, are arranged in the door drive devices and door locks.

It is an object of the invention to extend the design possibilities of window or door wings.

The object is achieved by a window or door leaf with the features of claim 1.

In a window or door leaf according to the invention, the fitting is fastened to at least one of the glass panes and / or to the spacer of the glass element or forms part of the spacer. This measure is based, in particular, on the knowledge that the spacer, which is present in any case for multiple glazed panes, is sufficiently stable to act as a fitting carrier. In contrast to the practice that is often present in the field, fitting to the casement to attach, so the fitting is attached to the spacer of the glazing and / or directly on the glass. The window or door must then not necessarily be equipped with a sash, but can be virtually completely made of glass. If necessary, however, a sash may be provided despite attachment of the fitting on the spacer.

Due to the use of the spacer as a fitting carrier a glass wing including the associated fitting can be easily combined with an existing example of plastic or wood usual frame profile. Preferably, therefore, the shape and / or the width of the spacer are adapted to a predetermined frame profile. A window manufacturer can then fall back on existing sash profiles when providing a wing according to the invention with a frame. He does not have to worry about providing a fitting, as it is already integrated in the glass wing.

It should be noted that a glass sheet in the sense of the invention may in principle be made of any transparent material, e.g. from a glass material in the actual sense, from Plexiglas or from a transparent plastic. A combination of different materials is conceivable.

According to the invention at least one outer side of the glass element at least one coupling element is provided which can be brought into engagement with a counter-coupling element of a sash element in order to attach the sash element, preferably interchangeable, to the window or door sash. In this way, for example, a frameless glass wing can be retrofitted with a sash. The wing frame element may be a frame-like Component or act to a simple decorative element, which frames the glass only partially. An interchangeable sash member has the advantage that, if desired, a user can change the design of the window or door by, for example, attaching differently colored and / or molded sash members. The coupling elements may be simple mechanical connecting elements such as socket pins or guide rails. In principle, it may also be advantageous for fixed glazing to provide coupling elements for interchangeable frame elements.

Further developments of the invention are specified in the dependent claims, the description and the accompanying drawings.

Preferably, the fitting is held exclusively by at least one of the glass sheets and / or by the spacer on the window or door leaf. The fitting can thus be completely integrated into the spacer or even be a part of the spacer, so that no casement for storing fittings is required.

The window or door can be designed in particular as a frameless glass wing. Such a glass wing has a particularly appealing visual appearance.

The spacer may, for. B. made of aluminum or a fiber composite material, in particular made of a glass fiber reinforced plastic. Such materials have a sufficiently high stability to wear the fitting safely. At the same time, the specific weight of said materials is comparatively low.

An embodiment of the invention provides that the spacer is designed as a peripheral edge compound, wherein the glass panes protrude at least partially together over the edge compound and thus define a receiving space for the fitting. The fitting can then be hidden in a sense in the receiving space, so that it does not affect the visual appearance of the wing.

Particularly preferably, the fitting is completely received in the receiving space, so that from the outside no beyond the edge of the wing protruding fitting parts are visible.

A further embodiment of the invention provides that in the or a further receiving space further at least one accessory device for the window or the door, in particular a drive for moving the window or door leaf relative to a window frame of the window or door, is arranged. The receiving space is thus used in this embodiment to equip a window or a door with additional functionality.

A window or door wing according to the invention can also be provided with at least one heating and / or cooling device, in particular with a Peltier element. Such a device may be provided in the region of the spacer or on one of the glass panes. The use of a Peltier element is advantageous in that one side of the wing can be heated by supplying power and at the same time the other side can be cooled. By reversing the page assignment can be reversed, so z. B. an interior cooled in the summer and can be heated in winter. In addition, a Peltier element can be used to generate electrical energy when exposed to sunlight.

In a window or door leaf according to the invention, at least one ventilation element such as a folding ventilator can also be integrated.

A special embodiment of the invention provides that at least one of the glass panes is designed for automatic darkening in the case of solar radiation. For this purpose, the glass sheet may be made of a photochromic material.

In the space between the panes, a shading device such as a roller blind can be arranged, whereby the wing is given a further functionality.

Preferably, the coupling element allows a plugging or pushing the sash element on the glass element. For the exchange of sash elements no special knowledge is required in such an embodiment. The replacement can thus be done quickly and easily.

A further embodiment of the invention provides that at least one of the glass panes has an absorption area designed for absorbing radiant energy, wherein means are provided for storing and / or forwarding the absorbed radiant energy to the spacer. The absorption region can be formed, in particular, by a blackened section of the glass element. Thus, the glass element of the window or door wing can be used for energy. The energy thus obtained by solar and / or artificial light radiation can be stored for example in an accumulator. By taking current from the accumulator then in turn accessories of the window or the door can be supplied with power. Thus, for example, a powered Wings with independent power supply are provided. Alternatively or additionally, it is possible to provide a heat storage using the absorption area, which keeps the wing warm. Thus, z. B. prevents the inner pane of a glass element starts overnight.

According to a particular embodiment of the invention, the glass element comprises at least three glass panes, which are held together by at least one spacer to form respective panes interspaces. In particular, a separate spacer may be provided in each case between two successive glass panes. However, it is also possible for three or more glass sheets to be formed by a one-piece, e.g. the middle glass pane are held together at the edge over the spacers. In such a triple or multiple glazed wing, any existing spacer for attaching a fitting and / or an accessory device can be used if necessary. For example, in a triple glazed wing, one of two existing spacers may be used to attach the fitting and the other spacers may be used to attach an accessory such as a wing drive. The functionality of a window or a door can thereby be extended.

The fitting can be designed in particular as a turn, tilt, Drehkipp- or sliding fitting. Preferably, the fitting comprises a driving or locking bar which extends at least partially along the outer border of the spacer. A window or door leaf according to the invention can also be provided with a fitting for a window or a door with a closing part attachable to the window frame or the door and one on the wing of the window or the door attachable, formed for a retaining engagement with the closure member locking element may be provided. The closing part is designed as an elongate closing rail and forms a continuous stop for the locking element along a longitudinal axis extending in the plane of the wing. By such a locking rail a uniform closing position can be ensured. Furthermore, the closing rail can also be used as a fitting carrier, for example for securing corresponding bearings. Thus, the stability of the connection between the sash and the frame can be increased. At the same time positional tolerances can be reduced by the closing rail. The seaming air can also be reduced. A reduction of the folding air is particularly advantageous when using a frameless glass wing, since the corresponding locking elements such as traps or bolts can be designed shorter or with a lower extension stroke. Another advantage of the closing rail is an increase in thermal insulation and improved sound insulation.

Preferably, the closing rail can be pushed onto the frame or plugged on and / or latched to the frame. The closing rail can thus be quickly and easily attached to the frame and replaced if necessary.

The closing rail can be made of a metal, in particular of aluminum, or of a fiber composite material, in particular of glass fiber reinforced plastic. These materials have a comparatively low weight and high stability.

Preferably, the closing rail has at least one bearing element for supporting the wing on the frame. It must then be provided on the frame no separate warehouse.

This in Fig. 1 Partially shown window comprises a frame 11 and arranged in the frame 11 wings 13. Preferably, the wing 13 is movable relative to the frame 11, that is rotatable, tiltable and / or displaceable. In the illustrated embodiment, the wing 13 is designed as a frameless glass wing, that is, it is completely formed by a glass element 15. The glass element 15 here comprises three glass panes 19, which are separated by two spacers 17a, 17b are held together to form respective disc spaces 18a, 18b. The two spacers 17a, 17b are each designed as peripheral edge compound, wherein, as shown, all three glass panes 19 protrude beyond the edge composite, so that a total of two peripheral side receiving spaces 23a, 23b are formed. In the left-hand receiving space 23a in the picture there is arranged a fitting 25 which is shown only schematically and which comprises at least one displaceable driving or locking bar for actuating a closure of the window. In contrast, an electric drive 27 is arranged in the right in the image receiving space 23 b, which allows automatic opening of the wing 13. Both the fitting 25 and the drive 27 are completely accommodated in the respective receiving spaces 23a, 23b, that is to say that no components project beyond the edge of the glass panes 19.

The fitting 25 is not only arranged in the receiving space 23a, but in particular also attached to the associated spacer 17a. An exclusive attachment of the fitting 25 on the spacer 17a basically allows a waiver of a sash. The spacers 17a, 17b are optionally made of a metal such as aluminum or a fiber composite such as a glass fiber reinforced plastic. At the front of the outside of the glass element 15 in the picture coupling ribs 29 are provided, on which a not shown wing frame element can be plugged. On the opposite outer side of the glass element 15, a coupling rail 31 is provided, which has a dovetail-shaped cross-section and the attachment of a sash member 33 with a correspondingly shaped dovetail groove 35 is used. With the help of the coupling ribs 29 and the coupling rail 31 different sash elements 33 can be attached to the wing 13. In particular, can the color and / or the shape of a sash member 33 can be changed quickly and easily if desired.

The fitting 25 may be designed in particular as a rotating, tilting, Drehkipp- or sliding fitting in common construction. If necessary, in this case at most the width of the spacers 17a, 17b adapt, wherein in the case of broadening at the same time the insulating effect of the window is increased.

Means for filling the respective space between the panes 18a, 18b with a gas and / or for discharging a gas from the respective space between panes 18a, 18b can furthermore be provided on the two spacers 17a, 17b, as in FIG Fig. 1B is shown simplified. Specifically, in the left-side receiving space 23a, there is disposed a first gas refilling container 37 which contains a heat-insulating gas such as krypton or argon. In the right in the image receiving space 23b, a second gas refilling container 39 is arranged, which contains a colored gas. Via respective lines 40 and provided in the spacers 17a, 17b passages 45, the gas refill containers 37, 39 are connected to the respective disc spaces 18a, 18b. Controllable valves 41 serve to selectively enable or disable fluid communication between the gas refill containers 37, 39 and the associated inter-disc spaces 18a, 18b. In this way, if necessary, a refilling of the gas contained in the respective disc space 18a, 18b gas take place. Likewise, via not shown, through the spacers 17a, 17b passing and provided with respective valves discharge lines, a discharge of gas from the disc spaces 18a, 18b are caused. The two gas refill containers 37, 39 are detachably attached to the respective spacers 17a, 17b, so that they can be subsequently purchased, for example, in the form of cartridges. In the case of the second gas refill container 39, which contains the colored gas, a targeted darkening of the glass element 15 can be brought about by opening the valve 41.

Fig. 2 shows a non-inventive window with a frame 11 and a wing 13, which is designed in principle similar to that in Fig. 1 and 2 shown wings 13 and which is formed in particular exclusively by a glass element 15 without coupling element. At a spacer of the glass element 15 is an in Fig. 3 invisible locking element attached, for example in the form of a sliding lock pin. A cooperating with the locking element, attached to the frame 11 closing part is designed as an elongated locking rail 51, at the top of a stop rib 53 is provided. The stop rib 53 forms along its longitudinal extent a continuous stop for the locking element. The closing rail 51 is as shown in positive connection with the frame 11 and can be added in a simple manner by pushing or plugging an existing frame 11. An exchange of the locking rail 51 is fast and easy. The locking rail 51 ensures a uniform closing position and can be used as needed as a carrier for various fittings. In addition, by providing the closing rail 51, the folding air can be reduced. Instead of the individual stop rib 53, further stop and / or engagement elements may be provided on the closing rail 51.

A frame 11 'not belonging to the present invention is shown in FIG Fig. 3 shown. The illustrated frame 11 'has in a corner region 54 a milled recess 55, in which a fitting part 57 is inserted in the form of an L-profile. On the two legs of the L-shaped fitting part 57 three differently shaped plug-in projections 59a, 59b, 59c are provided. These are used for attaching or clipping a provided with a respectively suitable receptacle fitting part, so as for example a wing 13 as in Fig. 1A . 1B and 2 shown to be stored on the frame 11 '. The plug-in projections 59a, 59b, 59c can be adapted to common, commercially available fitting parts of wings, so that the fitting part 57 can effectively serve as a universal connection for fittings of all kinds. In addition, the fitting part 57 makes it possible to improve the visual appearance of the frame 11 'and to increase the stability of the window.
