WINDOW OR DOOR WINDOWS

Description

[0001] The present invention relates to a sash for a window or a door having the features of the preamble of claim 1.

[0002] There are window sash frames or door leaves that have a door or window handle for opening or closing, which is rotatably mounted on the frame on a bearing flange. EP 3 760 816 A1 discloses a holding device for door or window handles, which has a lower rosette that is mounted with a contact surface on a side facing the frame on the surface of the frame in an area near an edge of the frame by means of two screws. This has the disadvantage that a torque applied to the handle is transmitted via the lower rosette via the screws to a small area of ​​the frame, so that high forces act on the frame near the edge. This reduces the minimum achievable width of the frame, since the frame must withstand the torque.

[0003] EP 3 680 423 A2 shows a turning device for door or window handles, with a non-circular rosette that can be inserted into a recess in a door or window sash. By inserting the rosette directly into the sash, this prior art can indeed enable a very compact design of the turning device. However, as with EP 3 760 816 A1, there is the problem that the force transmitted directly from the handle to the sash via the rosette is too high for narrow window or door sashes.

[0004] WO 2018 / 224294 A1 shows a circular, bowl-shaped adapter for mounting a door handle on a window frame. The adapter is inserted into a circular recess in the sash. A base body is inserted into the adapter, which has pivoting clamping elements that engage a portion of the window frame behind the recess, thus securing the handle against axial withdrawal. The adapter is screwed into the window frame and has pins protruding from the underside to prevent rotation. These pins can be inserted into a portion located behind the recess in the sash with a corresponding star-shaped cutout. However, the pins result in a very concentrated force transmission, so this device is only suitable for wide window frames.The star shape also makes the device more difficult to manufacture and requires a process that can precisely produce these shapes and then fit the corresponding components together.

[0005] The object of the present invention is to provide a sash for a window or a door which is equipped with a handle element which can be designed in a space-saving manner so that a width of the frame is reduced.

[0006] The present invention solves this problem by means of a sash for a window or a door having the features of claim 1.

[0007] According to the invention, the sash for a window or door comprises a frame profile with a rotatable handle element, which has a lower rosette with a contact surface on which projections are arranged. A bearing flange, to which the handle element is fixed in a rotationally fixed manner, is rotatably mounted on the lower rosette. The frame profile has a recess with a shape deviating from the circular shape, in which a holding element for fixing the lower rosette is held in a rotationally fixed manner with an outer side. As a result, a torque applied to the handle element can be evenly distributed over the frame profile, so that the frame profile can be designed in a space-saving manner and have an attractive appearance. Furthermore, the handle element can be arranged at a small distance from an edge region of the frame profile by means of the holding element, which leads to further improved space savings and improved handling of the handle element.

[0008] Form-fitting in the sense of the present invention means that the respective components are adapted to one another in parallel planes of the respective relevant sections in such a way that one of the parts can be arranged in the other part in a direction parallel to these planes with as little play as possible.

[0009] According to the invention, the retaining element is bowl-shaped, with the lower rosette being inserted into the bowl-shaped retaining element. This allows the device to be designed to be particularly space-saving.

[0010] In particular, the outer side of the holding element has at least two projections and preferably at least six projections and in particular exactly six projections, so that a torque transmitted via the grip element to the holding element can be transmitted evenly to the frame profile and so that the holding element can be held in the frame profile with improved torsional strength without the frame profile being deformed and / or significantly deformed.

[0011] Essentially, the recess can have a diameter of, in particular, 20 mm to 35 mm, preferably 25 mm to 30 mm, and particularly preferably 28 mm to 29 mm, wherein the diameter is a diameter of a predominantly circular inner geometry and / or a diameter of an outer circumference of the recess, which is preferably a circle adjacent to the outermost point of the notches, so that the dimensions of the recess can be adapted to the holding element. The diameter of the outer circumference of the recess is larger than the diameter of the circular inner geometry.

[0012] The recess can, in particular, have a plurality of notches, so that an outline of the recess corresponds to an outline of the outer side of the retaining element, which is positively inserted into the recess. The recess is preferably substantially circular, wherein the notches can preferably be designed in the form of partial circles that protrude beyond the predominantly circular inner geometry of the recess, so that the recess has a shape that deviates from the circular shape. The shape of the recess can thus, in particular, resemble the shape of a rosette. This allows a particularly advantageous distribution of forces to the frame profile to be achieved via the retaining element.

[0013] In one embodiment, the notches each protrude beyond the inner geometry with a maximum depth of in particular 0.5 mm to 3 mm, preferably 1 mm to 2 mm and particularly preferably 1.1 mm to 1.2 mm, so that the holding element can be designed in a particularly advantageous and / or precisely fitting manner.

[0014] For the advantageous design of the recess, the notches preferably each have an outline that can correspond to at least a portion of a circle, i.e., a circular arc, which preferably has a diameter of 4 mm to 12 mm, in particular of 6 mm to 10 mm, and preferably corresponds to millimeters or particularly preferably to exactly 8 mm. The respective circular arc preferably has a radian measure of π / 2 radians to 3π / 2 radians, and particularly preferably of 3π / 4 radians to π radians.

[0015] An outline of the projections corresponds in particular to the notches, so that the holding element can be arranged in the recess with a particularly stable form fit.

[0016] The contour of the recess is essentially identical to the contour of the outer side of the retaining element, allowing the retaining element to be held in the recess in a rotationally fixed manner without play. The entire contact surface can, for example, be inserted into the recess in a rotationally fixed and form-fitting manner with an inner side of the retaining element. Alternatively, it is also possible for only the projections on the retaining element and / or on the lower rosette to be arranged in a form-fitting manner in the recess and / or the retaining element. This can, for example, save material.

[0017] The frame profile has a web in the area of ​​the recess, which has a width of 1 mm to 5 mm, and preferably 2 mm to 4 mm, in the insertion direction of the retaining element. This allows the frame profile to be manufactured using less material and thus cost-effectively.

[0018] Preferably, the frame profile can have, in particular, a web in the region of a notch, which is formed with a width of 1 mm to 10 mm, and preferably 2 mm to 7 mm, in the insertion direction of the retaining element. The web can form an additional contact surface for the retaining element.

[0019] The recess is arranged at a minimum distance of 1 mm to 2.5 mm, and preferably 1.2 mm to 1.4 millimeters, from the nearest outer edge of the frame profile. This enables a particularly space-saving design of the sash.

[0020] For advantageous production, the recess is preferably milled and / or punched into the frame profile.

[0021] For a particularly advantageous design of the sash, the frame profile and / or the retaining element and / or the handle element and / or the lower rosette and / or the bearing flange are preferably made of metal and / or plastic, with the metal preferably comprising aluminum. This enables a cost-effective design of the components.

[0022] To prevent it from being pulled out axially from the recess, the holding element is preferably fastened to a drive rod fitting arranged on the frame profile, in particular by means of at least one fastening means, which can preferably be at least one screw. The holding element can in particular also or alternatively be fastened to the frame profile and / or the drive rod fitting by gluing or clamping. The lower rosette and / or the holding element can each be fastened to one another and / or to the recess by means of at least one fastening means. The fastening means can in particular comprise screws and / or a hexagon socket and / or a hexalobular socket and preferably have at least one pivotable area, which can each be pivoted into an opening in the holding element and / or the lower rosette. In this way, the lower rosette and / or the holding element can be secured against being pulled out axially.

[0023] For improved security, the holding element is designed to transmit a torque of, in particular, 80 Newton meters (Nm) to 150 Nm, preferably 90 Nm to 110 Nm, and particularly preferably more than 100 Nm. The holding element can be held in the recess in a dimensionally stable, form-fitting, and rotationally fixed manner, thus meeting the requirements of the DIN EN 13126-3:2012-02 standard, particularly without the gripping element twisting. This allows the gripping element to be positioned particularly close to an edge region of the frame profile without a corresponding torque leading to deformation of the frame profile.

[0024] The handle element is preferably arranged in the bearing flange in a rotationally fixed manner, so that the handle element and the bearing flange are mounted on the frame profile so that they can rotate about an axis.

[0025] The wing, in particular the handle element, can have a lock by means of which the wing and in particular the handle element can be locked and unlocked. For this purpose, the lock preferably has a cylinder arranged in the handle element into which a key can be inserted. By turning the key, the lock can be locked or unlocked, and the wing can thus be locked or unlocked, which preferably occurs by appropriately preventing or allowing rotation of the handle element.

[0026] The present invention is explained in more detail below with reference to several drawings. They show: Figure 1 is an exploded view of a wing according to the invention; Figure 2 is a view of a recess according to Figure 1 ; Figure 3 a cross-section of a sub-rosette according to Figure 1 Figure 4 shows an exploded view of a wing according to the invention according to a further embodiment.

[0027] In Figure 11 shows an exploded view of a sash according to the invention for a window or for a door with a frame profile 4 and a rotatable handle element 2. The sash has a lower rosette 21 with a contact surface 29 on which projections 26 are arranged. A bearing flange 22 is rotatably mounted on the lower rosette, to which the handle element 2 is fixed in a rotationally fixed manner, so that the handle element 2 is mounted on the lower rosette 21 so as to be rotatable about an axis H. The handle element 2 is fixed here in particular to the bearing flange 22 by means of a fastening means 28 designed as a screw.A bolt 23 designed as a square, which in particular has a square cross-section, is inserted into a tunnel 27 in a rotationally fixed manner in the bearing flange 22, so that a rotation of the handle element 2 via the bearing flange 22 leads to a rotation of the bolt 23, whereby an espagnolette fitting 5 arranged on the frame profile 4, which has a groove into which the bolt can engage, is optionally actuated, by means of which the window or door can be locked.

[0028] The frame profile 4 in Figure 1 has a recess 1 with a shape other than circular. The recess 1 is preferably milled or punched into the frame profile 4.

[0029] The recess 1 is in Figure 2shown enlarged. It has a predominantly circular inner geometry 12, which essentially has a diameter D, in particular from 20 mm to 35 mm, preferably from 25 mm to 30 mm and particularly preferably from 28 mm to 29 mm. The recess 1 also has a plurality of notches 13, each of which protrudes radially beyond the inner geometry 12 with a maximum depth C of in particular from 0.5 mm to 3 mm, preferably from 1 mm to 2 mm and particularly preferably from 1.1 mm to 1.2 mm. The notches 13 each have an outline which corresponds to at least a section of a circle with a diameter of in particular from 4 mm to 12 mm, preferably from 6 mm to 10 mm and particularly preferably from approximately 8 mm or exactly 8 mm. The notches 13 are therefore each designed in the shape of a circular arc. The respective circular arc preferably has a radian measure of π / 2 radians to 3π / 2 radians and particularly preferably of 3π / 4 radians to π radians.A diameter B of an outermost circumference of the recess 1, which is a circle adjacent to the outermost point of the notches 13, is in particular from 20 mm to 35 mm, preferably from 25 mm to 30 mm and particularly preferably from 28 mm to 29 mm, wherein the diameter B is greater than the diameter D.

[0030] Preferably, the recess 1 has an axis of symmetry S such that half of the notches 13 lie on each side of the axis of symmetry S, wherein a length of a circular arc lying on both sides of the recess 1 between the respective halves of the notches 13, through the center of which the axis of symmetry S runs, which extends in particular horizontally, is greater than a length of circular arcs lying between the half of the notches 13 lying on the corresponding side of the axis of symmetry S. Circular arcs emanating from the respective center point of the circles, of which the notches 13 form a part, preferably have a radian measure of π / 5 radians to π / 3 radians and particularly preferably of π / 4 radians.Between the centers of the respective outer notches 13, which lie on opposite sides of the symmetry axis S, an arc of the circular inner geometry 12 preferably has a radian dimension of π / 4 radians to π / 2 radians, and particularly preferably of π / 3 radians. The recess 1 also has, in particular, a vertically extending symmetry axis V.

[0031] The circular arcs running between all notches 13 are arranged concentrically, so that they form the predominantly circular inner geometry 12 of the recess 1. The recess 1 optionally has predominantly the shape of a rosette. The recess 1 is as in Figure 1 or 2 with a smallest distance A of in particular 1 mm to 2.5 mm and preferably 1.2 mm to 1.4 mm from a nearest outer edge 41 of the frame profile 4.

[0032] In the recess 1, a shell-shaped holding element 3 is held in a form-fitting and rotationally fixed manner on an outer side 32, in particular on the outer side 32 of a projection 321 protruding from a shell, into which the contact surface 29 is inserted in a form-fitting and rotationally fixed manner with an inner side 31 of the holding element 3. The lower rosette 21 rests against a base 35 of the holding element 3. The projections 26 on the contact surface 29 engage in a plurality of receptacles 33 in the inner side 31 of the holding element 3. The outline of the outer side 32 of the holding element 3, in an area held in the recess 1, in particular of the projection 321, essentially corresponds to an outline of an inner side 11 of the recess 1. As a result, the holding element 3 is held in the recess 1 in a plane that runs parallel to the plane of the circular inner geometry 12, essentially without play.

[0033] In Figure 3 is a cross section of the lower rosette 21 from Figure 1 shown, which is inserted into the holding element 3, wherein the contact surface 29 has the described projections 26, which engage in the receptacles 33 in the holding element 3. The lower rosette 21 is essentially fastened to the holding element 3 by means of two fastening means 25. The fastening means 25 have a pivotable area, each of which can be pivoted into an opening 37 in the shell 322 of the holding element 3 and which secures the lower rosette 21 against axial withdrawal from the holding element 3.

[0034] The outer side 32 of the holding element 3 has according to Figure 1at least five projections 36 and preferably at least six projections 36 and in particular exactly six projections 36. An outline of the projections 36 corresponds to the notches 13. In the region of the recess 1, the frame profile 4 has a web which, in the insertion direction of the holding element 3, has a width T of 1 mm to 5 mm and preferably of 2 mm to 4 mm. The lower rosette 21 is inserted into the shell-shaped holding element 3.

[0035] The bottom 35 of the holding element 3 is arranged in the region of the projection 321 in the plane of the recess 1 and the outer side 32 protrudes from the frame profile 4 in the region of the shell 322.

[0036] To protect against axial withdrawal from the recess 1, the holding element 3 is fastened to a drive rod fitting 5 arranged on the frame profile 4, in particular by means of two screws 34, wherein the lower rosette 21 is preferably also fastened to the holding element 3 by means of two fastening means 25.

[0037] The holding element 3 can preferably transmit a torque of in particular 80 Nm to 150 Nm, preferably from 90 Nm to 110 Nm and particularly preferably more than 100 Nm to the frame profile 4, wherein the holding element 3 is held in the recess 1 in a dimensionally stable and form-fitting and / or rotationally fixed manner, so that the requirements of the standard EN 13126-3:2012-02 are met, in particular without the handle element 2 twisting and / or preferably without the frame profile 4 deforming.

[0038] The frame profile 4 and / or the retaining element 3 and / or the handle element 2 and / or the lower rosette 21 and / or the bearing flange 22 are preferably made of metal and / or plastic, with the metal preferably comprising aluminum. A rosette 24 can optionally be attached to the lower rosette.

[0039] Fig. 4 shows a wing according to a further embodiment of the present invention, wherein here the wing can be locked by means of a lock 6 which has a cylinder 61 with a slot 62 into which a key 63, in particular a rotatable key, can be inserted for locking or unlocking the lock 6, i.e. for locking and unlocking the wing, in particular the handle element 2.
