Description

The invention relates to a frame of a door or a window with at least two frame elements, which is associated with at least one cover layer, wherein each of the frame elements comprises an inner profile oriented toward a room side and an outer profile oriented towards an outer side.

From practice it is known to assemble a frame of a door or a window made of a plurality of aluminum-made frame members, which is associated with a filling, wherein each of the frame elements comprises an inner profile oriented toward a room side and an outer profile oriented towards an outer side. As a frame elements two longitudinal side elements and two end-side elements are generally provided, wherein the one of the longitudinal side elements of a hinge side and the other of the longitudinal side elements is associated with a closing side and the respective inner profile is equipped with the bands and the lock. The composite of the frame elements frame has either a filler filling or essay filling. The inner profiles and outer profiles of the frame are designed as hollow chamber profiles, between which a thermal separating web is firmly pressed. The thermal divider serves to avoid heat or cold bridges. The good thermal conductivity the aluminum frame members results in a difference between an outside temperature on one side of the frame and an internal temperature on the other side of the frame to different changes in the length of the outer profiles to the length of the inner profiles, in particular the temperature fluctuations on the outside seasonally relative big and relatively small on the inside. The firm compression of the thermal separating web between the outer profile and the inner profile leads to induced stresses and as a result to an undefined elastic deformation of the inner profile and thus of the door leaf. This deformation has the consequence that a between the frame elements of the wing and the frame elements of the wing overlapping frame of the circumferential seal partially no longer rests between the surfaces to be sealed, whereby unwanted drafts may occur, especially in winter. Furthermore, the deformation causes a poor match of the locking points of the wing and the frame, wherein in an extreme case, an open wing at a large temperature difference is not properly locked. To reduce the above drawbacks, it is known to make the thermal barrier by a cross-sectional reduction with an increased elasticity or the inner profile with a geometry with a greater resistance to deformation.

The frame supports or supports an inner and / or outer cover layer, which is arranged either overlapping between the frame parts or the frame parts. The cover layer can be any functionally, for example, transparent, and / or make visually appealing and covers, for example, the filling. Of course, can also provide a cover layer without a further filling.

The invention has for its object to provide a frame of the type mentioned above, which has only a slight tendency to change the shape of a relatively large temperature gradient across its thickness.

According to the invention the object is achieved by the features of the independent claim.

The subclaims represent advantageous embodiments of the invention.

A frame of a door or a window comprises at least two frame elements to which a filling is assigned, wherein each of the frame elements comprises an inner profile oriented to a room side and an outer profile oriented to an outer side. The inner profile is so positively or positively connected to the outer profile, that the inner profile is displaceable relative to the outer profile in the direction of a longitudinal axis.

A preferred use of the frame as sash of a door, in particular a front door or apartment door.

Since the connection between the outer profile and the inner profile allows a relative movement in the direction of the longitudinal axis of the two profiles having the greatest length changes, the inner profile is decoupled from the outer profile, whereby stresses due to a thermally induced change in length and associated changes in shape are avoided or substantially reduced are. Furthermore, with the proposed solution, a reduction of the individual parts used in the prior art goes hand in hand, since no divider is used.

According to a development, a slidable in the direction of the longitudinal axis clip connection is provided between the inner profile and the outer profile. Preferably, the outer profile has two mutually spaced clip arms, which cooperate with undercuts of the inner profile, wherein the inner profile is formed as a rectangular in cross-section hollow chamber profile having at its one broad side the undercuts. The outer profile and the inner profile can be produced in a drawing or extrusion process, for example, an aluminum alloy or a plastic. Since due to the uniaxial decoupling, so the displaceability in the direction of the longitudinal axis, the similarity of the linear expansion coefficient is of minor importance, it is possible, for example, the inner profile of an aluminum alloy and the outer profile of a plastic or vice versa. The undercuts may be substantially integrated into the inner profile, be designed as a kind Klipsnasen, or as Gegenklipsarme, which extend away from the inner profile.

Preferably, the outer profile is formed as a cross-sectionally L-shaped hollow profile and having at its long leg, the spaced apart clip arms. The outer profile is arranged such that it faces outward with the free end face of its short leg, and the long leg is aligned parallel to the inner profile. Accordingly, the outwardly facing surface of the short leg is relatively small, which has a positive effect on the heat transfer, and the outwardly facing surface of the long leg, which faces the Klipsarme having surface, for example, can serve for supporting a surface heat insulation.

In a further embodiment, the outer profile on a frame outer side profile end face on at least one over the entire length extending convex Dichtwölbung. The sealing curvature is provided for abutment against a sealing rubber and may in particular comprise two side-by-side formed sealing curvatures, which extend in a mounted state of serving as the sash of a door frame in a door gap.

In order to minimize heat transfer from the outer profile to the inner profile and at the same time to create a relatively small contact surface, spacer lugs are preferably arranged between the clip arms. For example, if two rib-shaped spacer lugs formed on the outer profile and is located between these spacer lugs formed on the inner profile rib-like spacer nose, then the outer profile against the inner profile against a lateral displacement, which does not correspond to the longitudinal direction, secured.

In an embodiment, the inner profile on its side opposite the broad side with the undercuts broadside on a frame outer side profile end hinausersteckenden extension, which is provided for holding a seal with a groove. The projection forms a kind of fold, which is formed on the inner profile, With a mounted against a frame fitting seal an additional sealing layer is created, which causes an improvement in the heat transfer coefficient (U-value) and a reduction in air permeability in the convection zone of the door rebate wherein a first seal acts on the outside between the frame and the door leaf formed by sash and filling.

According to an alternative development, at least one displaceable in the direction of the longitudinal axis between the inner profile and the outer profile Tongue and groove connection provided. Conveniently, the tongue and groove connection in cross-section T-shaped or dovetail-shaped. Also, the T-slot or dovetail connection between the inner profile and the outer profile allow relative movement of these two profiles in the direction of the longitudinal axis, whereby at a different change in length of the two profiles, in particular due to different temperatures on the outside and inside, an undesirable deformation avoided over the length or substantially reduced.

Since the change in length over the height of the door, which is determined by the length of the longitudinal frame members, for the thermally influenced deformation is of particular importance, the clip connection or the tongue and groove connection is preferably associated with the longitudinal frame members.

Conveniently, this is associated with a longitudinal side frame member of a closing side and the other longitudinal side frame member of a hinge side. For example, can be attached to the corresponding inner profiles bands or closing elements.

Advantageously, the filling is fixed on the outside and / or the inside of the frame elements. On the outside, the filling or its cover layer is fixed on the free end face of the short leg of the outer profile, so that a heat transfer surface is dimensioned relatively small in this area. The filling covers the frame, which is therefore not visible to a viewer in a closed door, which is why the frame profiles can be made of any materials or material combinations that do not interfere visually.

Preferably, at least one of the frame members a disposed within the frame function carrier is attached. The function carrier can be frictionally and / or positively and / or cohesively fixed to the frame side retaining strips or mounting flanges or mounting straps. The function carrier can have any desired properties and / or support components in order to functionalize the frame. For example, in the case of a filling that is transparent to radiation at least on one side, the function carrier may comprise photovoltaic elements which provide a voltage supply for electrical / electronic components which may likewise be assigned to the function carrier. The function carrier arranged below or between cover views of the filling, that is to say between the outside and the inside of the frame, has no influence on the optical properties of the door and can be adapted as desired to the prevailing requirements. Of course, it is also possible to arrange the function carrier between an insulating layer of the filling. The function carrier may, for example, have a rotary drive for pivoting the frame.

Preferably, the function carrier is fixed on the long leg of the outer profile. The function carrier can be screwed, riveted, glued or the like connected to the outer profile.

In a further embodiment, the outer profile in its short leg on a receiving groove for a terminal block for fixing the function carrier on the long leg. In the terminal strip may be a known from the prior art glass retaining strip or other holder that fixes the function carrier on the long leg of the outer profile.

The function of the carrier is designed to store heat or as insulation against sound, heat, radiation, pollutants or fire. To assign safety functions to the door, the function carrier is resistant to fire or burglary. Here, the function carrier may be plate-shaped and extend substantially over the entire frame. In order to integrate further functionality into the frame, the function carrier preferably comprises sensors and / or actuators, in particular actuators of a locking system, or sensors of an image acquisition device or a toner detection device or position sensors or vibration sensors. For example, a fingerprint recognition sensor may be assigned to the function carrier, which comprises an evaluation device and a memory device for fingerprints, and which actuates a locking mechanism for opening a latch when a stored fingerprint is detected. The sensors are expediently for evaluating the sensor signals and / or controlling the actuators and / or the actuators with a computer device of a home automation device in conjunction.

It goes without saying that the features mentioned above and those yet to be explained below can be used not only in the respectively specified combination but also in other combinations. The scope of the invention is defined only by the claims.

The invention will be explained in more detail below with reference to several embodiments with reference to the accompanying drawings.

A door 1 comprises a door leaf 2, which is essentially composed of a frame 3 with an associated filling 4, wherein the filling 4 in the present case comprises an outer cover layer 5 and an inner cover layer 6 and an insulating layer 7 arranged between the cover layers for thermal insulation. The frame 3 has two longitudinal frame members 8 and two wide-sided frame members 9, which are each connected at right angles, wherein the one longitudinal frame member 8 a closing side 10 and the other longitudinal frame member 8 a hinge side 11 of the door 1 is assigned. Each of the longitudinal frame members 8 is made of an inner profile 12 and a non-positively or positively connected thereto outer profile 13 composed that the inner profile 12 relative to the outer profile 13 in the direction of a longitudinal axis according to the double arrow 14 is displaceable. The inner profile 12 on the band side 11 is fixedly connected to one end of a band 15 whose other end is coupled to a frame 16, which is composed essentially of a Innenzargenhohlprofil 17 and a Außenenzargenhohlprofil 18 with a disposed therebetween thermal separation profile 19. The Innenzargenhohlprofil 17 is firmly pressed with the separation profile 19 and the separation profile 19 with the outer frame hollow profile 18.

To avoid deformation of the door leaf 2 due to relatively large temperature differences between the outside and the inside of the door 1, the different elongations of the outer profile 13 and the inner profile 12 of the longitudinal frame members 8 result, between the outer profile 13 and the inner profile 12 clip connections 20th , which fix the outer profile 13 relative to the inner profile 12 in two axes and allow movement in one axis according to the double arrow 14. Of course, the clip connections are only exemplary embodiments of such a connection with a degree of freedom. It is also possible to realize, for example, a tongue and groove joint in T-shape or dovetail shape or the like to achieve the same effect.

The outer profile 13 is formed as a cross-sectionally L-shaped hollow section with a long leg 21 and a short leg 22 extending at right angles thereto. The short leg 22 of the outer profile 13 extends in the frame 16 and the free end face forms a support for the outer cover layer 5 of the filling 4. Furthermore, the outer profile 13 on a frame outside profile end face 28 at least one over the entire length extending convex Dichtwölbung 38th on. The long leg 21 of the outer profile 13 is parallel aligned to the rectangular cross-section rectangular hollow section of the inner profile 12 and extends by means formed on the outer profile 13 spacer lugs 23 spaced from a broad side 24 of the inner profile 12. The outer profile 13 facing broad side of 24 of the inner profile 12 has hook-shaped undercuts 25, which with on the External profile 13 molded clip arms 26 cooperate. The hook-shaped undercuts 25 may alternatively be formed in the form of Gegenklipsarmen 27 on the inner profile 12. In addition, located on the frame outer side profile end face 28 of the inner profile 12, a spacer cam 29 which rests against the outer profile 13.

The wide side 24 with the undercuts 25 opposite broad side 30 of the inner profile 12 has a beyond the frame outer side profile end 28 überersteckenden extension 31 which forms a fold with the profile end face 28 and for holding an inside seal 32, which is in the closed state of the door 1 supported on the frame 16, is provided with a groove 33. The extension 31 and the corresponding broad side 30 of the inner profile 12 are spanned by the inner cover layer 6. On the outside of the door 1 of the frame 16 is associated with a circumferential seal 34 which rests biased in the closed state of the door 1 on the outer cover layer 5 of the filling 4.

If a relatively high temperature prevails on the outside of the door 1, for example as a result of direct sunlight, the outer profile 13 made of an aluminum alloy or a plastic undergoes a relatively large elongation in relation to the inner profile 12. In a frame known from the prior art this deforms with an inward curvature. In the present frame is after Fig. 4 a change in length of the outer profile 13 without effect on the change in length or Deformation of the inner profile 12 due to the connection with the degree of freedom in the direction of the longitudinal axis of the frame. 3

If the temperature on the inside of the door 1 is higher than on the outside of the door, as is the rule, for example, in winter, then the outer profile 13 undergoes a reduced in relation to the inner profile 12 elongation, at a fixed connection, as of a Bimetallic known, leading to a curvature towards the outside of the door 1. Due to the connection with the one degree of freedom in the direction of the longitudinal axis of the frame 3, a displacement of the inner profile 12 takes place relative to the outer profile 13, as can be seen in Fig ..

To assign the door a further functionality, a resting on the long leg 21 of the outer profile 13 function carrier 35 is arranged, which can be screwed or glued to the outer profile 13. It is also possible to additionally or alternatively fix the function carrier 35 to the long leg 21 of the outer profile 13 in a force-fitting manner, for which purpose the outer profile 13 has a receiving groove 36 in its short leg 22 for a clamping strip 37 which is known from the prior art Glashalteleiste acts and is attached.

The function carrier 35 may, for example, extend over the entire inner surface of the door leaf 2 and have heat-insulating and / or sound-insulating and / or burglary-resistant and / or bullet-proof properties. In addition or as an alternative, it is possible to associate with the function carrier 35 actuators, for example a closing mechanism, and / or sensors, for example an image and / or tone detection device. In particular, the actuators and sensors can be connected via appropriate interfaces wireless or wired with a computer, preferably a home control. reference numeral 1. door 20th clip connection Second door 21st long thigh v. 13 Third frame 22nd short thigh v. 13 4th filling 23rd Distance nose 5th outer cover layer 24th Broadside of 12 6th inner cover layer 25th undercut 7th damp course 26th clip arm 8th. longitudinal frame element 27th Gegenklipsarm 28th Profile End Faces 9th wide-sided frame element 29th spacer cams 30th Broadside of 12 10th closing side 31st extension 11th hinge side 32nd poetry 12th internal profile 33rd groove 13th outer profile 34th poetry 14th double arrow 35th officials 15th tape 36th receiving groove 16th frame 37th terminal block 17th Innenzargenhohlprofil 38th sealing vault 18th Außenzargenhohlprofil 19th separation profile
