Description

[0001] The invention relates to a frame according to the preamble of claim 1, a window comprising a frame according to claim 14 and a door comprising a frame according to claim 15.

[0002] In the prior art, windows and doors are known that comprise frames, wherein one side and / or part of the frame is lined with fixed panels, such as glass panes, and other parts form a stop for a casement window. To separate the areas from each other, the frames have so-called locking bars. It is also known to attach the panels and window sash to the frame from the same side, usually the inside. This necessitates that the locking bars be robust and large to provide the required stability. They therefore detract from the frame's appearance. Nevertheless, the locking bars must ensure that the panels are securely held and that the casement window is reliably stopped.

[0003] From DE 20 2008 014 630 U1, a window frame is known by means of which a variety of visually interesting window fronts can be designed by incorporating a circumferential rebate with a sloping surface between the mullion and the rest of the frame. However, the mullions must still be designed to be robust and wide in order to reliably accommodate the window pane and the window sash side by side.

[0004] There is therefore a great need for a frame, a window comprising a frame, and a door comprising a frame, all of which are slim and thus aesthetically pleasing, while still allowing for the integration of at least one panel and at least one sash. Particular attention is paid to the stability and reliability of the frame. Furthermore, the frame, window, and door should be cost-effective to manufacture. The invention aims to provide such a frame, as well as a window and a door comprising such a frame.

[0005] This problem is solved in a surprisingly simple but effective way by a frame according to the teaching of claim 1, a window comprising the frame according to the teaching of claim 14 and a door comprising the frame according to the teaching of claim 15.

[0006] According to the invention, a frame, in particular a blind frame, preferably made of wood, is proposed, wherein the frame comprises a surround and at least one bar which is connected to the surround at two connection points to divide the surround into at least two areas, wherein at least one first area is designed to receive a panel with a first circumferential rebate and wherein at least one second area is designed to receive a sash with a second circumferential rebate, wherein the frame comprises an inner side and an outer side opposite the inner side. The frame is characterized in that the first circumferential rebate is arranged on the outer side, the second circumferential rebate is arranged on the inner side, and that at least two corresponding inclined surfaces are formed between the connection points and the bar, wherein the inclined surfaces are arranged rotated relative to each other.

[0007] The basic idea of ​​the invention is that by alternating the fixed panel and the sash, a step can be created in the window plane, allowing the rebates to be offset from each other and therefore positioned closer together in the frame plane. This allows the mullion to be designed more slender and thus more visually appealing, while still maintaining sufficient stability.

[0008] The frame serves to provide one or more mounting surfaces for placement on or within an opening in a building structure, such as a wall. Preferably, the frame forms a window and / or a door and / or parts of a window and / or a door. The frame is preferably made partially or entirely of wood, although other materials, particularly solid materials, are also conceivable. The frame is generally rectangular, but any other shape is possible. The frame includes at least one mullion that divides the frame into at least two sections. The mullion can, in principle, be arranged at any angle. Preferably, however, it is positioned vertically (in which case it is also called a post or mullion) or horizontally (in which case it is also called a transom). Furthermore, it is conceivable to have a curved mullion, but preferably the mullion is straight.It is particularly preferred that the frame comprises at least two to twenty bars that divide the frame into several sections. Most preferably, the frame comprises at least two, three, four, five, six, seven, eight, nine, ten, eleven, twelve, thirteen, fourteen, fifteen, sixteen, seventeen, eighteen, nineteen, or twenty bars, the bars being of the same or different designs. It is also conceivable that one or more bars begin and / or end at other bars. If one bar begins and / or ends at another, the other bar accordingly has a connection point instead of a frame. The number of sections depends not only on the number of bars but also on their arrangement.Preferably, the frame comprises at least two, three, four, five, six, seven, eight, nine, ten, eleven, twelve, thirteen, fourteen, fifteen, sixteen, seventeen, eighteen, nineteen or twenty first areas and / or at least two, three, four, five, six, seven, eight, nine, ten, eleven, twelve, thirteen, fourteen, fifteen, sixteen, seventeen, eighteen, nineteen or twenty second areas, wherein the first areas and / or the second areas may be designed in the same or different ways.

[0009] At least one area is designed to receive a panel with a first circumferential rebate. The panel is fixed to the frame and the mullion and cannot be easily removed from the frame. Removal or adjustment for repair and / or maintenance purposes can be provided, but this is generally possible without tools. Preferably, the panel is a fixed glazing unit. The circumferential rebate serves to receive and hold the panel. Additionally, suitable means for mounting retaining elements and / or covers can be arranged on the circumferential rebate to hold and / or secure the panel.

[0010] The frame further comprises at least a second area designed to receive a sash. This second area includes a circumferential rebate. The sash can be rotated, pivoted, offset, and / or moved away from the frame. The rebate serves, in particular, to create a tight seal for the sash. For this purpose, the frame preferably includes hinges and / or rails formed and / or arranged between the frame and / or the latch and the sash. Preferably, at least one locking mechanism is formed on the sash, the frame, and / or the latch in the second area, enabling the sash to be secured to the frame in a closed position. This allows the sash to be locked so that it cannot be opened, or can only be opened from the inside using a handle.

[0011] The frame has an inside and an outside opposite the inside. The inside is the side that, when used as intended (installed in a building structure), lies within the building structure, while the outside is on the other side of the building structure, i.e., outside. The inside and outside can also be defined by the installation and be identical in design. The inside and outside are the flat surfaces of the frame.

[0012] The first circumferential rebate is located on the outside. This means the panel is positioned against the rebate from the outside and secured with suitable means. This positioning and securing can be done during the frame's manufacturing process. It is also conceivable that the securing means are removable, allowing the panel to be replaced and / or repaired if damaged.

[0013] The second circumferential rebate is located on the inside and is therefore oriented exactly the opposite of the first circumferential rebate. This results in the sash being guided against the frame from the inside. Hinges and / or tracks, in particular, represent a weak point for the window with regard to safety. Therefore, it is preferable if the hinges and / or tracks can be arranged on the inside. However, the invention is not limited to a correctly installed frame; it is also conceivable to install the frame at an angle. For example, this can allow compliance with fire safety regulations that stipulate that a door and / or window must open outwards. The terms "inside" and "outside" are therefore used for the sake of clarity in the claims.

[0014] As described above, the staggered orientation of the areas where panels are arranged and the areas designed for the sash attachment results in a slimmer profile for the mullions, thus creating a more visually appealing overall result. This slimming refers to the mullion's extension within the plane of the frame. This slimming effect can be further enhanced by arranging the inner and outer rebates on different, parallel planes. To ensure a secure connection between the mullion and the frame despite the load on both sides, the joint and the mullion each feature two corresponding angled surfaces, rotated relative to each other. This prevents the mullion from shifting in either direction. In other words, the angled surfaces create a positive fit between the joint and the mullion.This results in great stability, even with a slim design of the bar.

[0015] The term "fold" refers to a step on an edge of the frame and / or the bar.

[0016] The term "twisted" refers to inclined surfaces that are twisted relative to each other about an axis, where the axis runs in or parallel to the inclined surfaces.

[0017] The term "panel" refers to a flat building element, preferably a single- or multi-pane window pane. A panel can also be a sheet made of wood, metal, plastic, and / or a composite material.

[0018] The term "sash" refers to a part of the frame that is movable relative to the surrounding structure. The sash can be designed, in particular, as a window sash and / or a door sash. The manner in which the movement is achieved relative to the surrounding structure is, in principle, arbitrary. Preferably, it is a casement sash, reversible sash, tilt sash, tilt-and-turn sash, hinged sash, pivot sash, bottom-hung sash, sliding sash, and / or folding sash.

[0019] The frame makes it possible to provide an attractively slim design comprising one fixed element and at least one opening element, while being both safe and cost-effective to manufacture. In particular, the frame is stable and therefore durable.

[0020] Advantageous further developments of the invention, which can be implemented individually or in combination, are presented in the dependent claims.

[0021] It is conceivable that the corresponding inclined surfaces are arranged on opposite sides of the bolt and are rotated in the direction of the bolt. The bolt, in its basic form, has an elongated, preferably cuboid, shape, with the end faces connected at the joints. Inclined surfaces are formed on each of the two end faces. These lie on opposite sides of the bolt body at the end face. A rotation in the direction of the bolt means that the inclined surfaces are rotated about an axis that runs in or parallel to the end face, in particular parallel to an edge or a tangent to the edge of the end face. If the basic shape of the bolt is a cuboid, the inclined surfaces, together with the end face of the cuboid and a conceivable cross-sectional area at the opposite edge of the inclined surface, form a trapezoidal prism or a triangular prism.This design is simple to manufacture, yet effective in terms of frame stability. The inclined surfaces are preferably oriented orthogonally to a plane of the frame spanned by the frame. The rotation in the direction of the beam and the arrangement on both sides ensure that the beam is bounded in both directions by a positive fit. Due to the orthogonal arrangement to the frame plane, the beam is bounded on both sides in a primary load direction, namely within the plane of the frame. This results in particularly stable frames.

[0022] In a further development of the invention, it is conceivable that the inclined surfaces are arranged at a distance from one another and connected by a connecting surface. The connecting surface is formed correspondingly on the frame and on the bar. On the bar, the end face of the bar preferably forms the connecting surface. Particularly preferably, the angle formed by the first inclined surface and the connecting surface is equal to the angle formed by the second inclined surface and the connecting surface. Alternatively or additionally, it is conceivable to arrange the connecting surface parallel and / or tangentially to a section of the frame in which the connection point is located. In this way, the inclined surfaces can be designed such that they do not penetrate deeply into the frame, and the frame can be designed to be more stable, while the inclined surfaces can still be designed with a sufficiently steep angle.This means the frame can be designed to be slimmer, even with regard to the framing, while still remaining stable.

[0023] Furthermore, it is conceivable that the twist of the inclined surfaces is between 10° and 80° with respect to the frame and / or identical for at least two inclined surfaces. A twist in this range promotes the necessary friction for the positive fit without excessively stressing the wood. In other words, the lateral force cannot compress the wood of the rail to such an extent that the rail is pulled out of the inclined surface. The angle is particularly preferably at least 20°, 30°, 40°, 50°, 60°, 70°, or 80° and / or at most 80°, 70°, 60°, 50°, 40°, 30°, or 20°. Most preferably, the angles are identical, as this ensures a uniform load distribution on the frame and / or the rail.

[0024] The term "in relation to the frame" refers to a principal axis and / or a tangent in the area of ​​the connection point of the basically elongated frame, which forms an angle with the inclined surface.

[0025] It is also conceivable that the inclined surface extends over a maximum of 70% of the depth of the frame and / or the transom. The depth of the frame is the dimension that runs from the inside to the outside, i.e., perpendicular to the surface plane of the frame described elsewhere. This allows for the design of other elements, in particular a visually appealing transition at the side surfaces. Furthermore, displacement or warping in the depth direction can be prevented if appropriately interlocking elements are arranged. Preferably, the inclined surfaces extend over a maximum of 65%, 60%, 55%, or 50% of the depth. To still ensure stability, the inclined surfaces preferably extend over at least 30%, 35%, 40%, 45%, or 50% of the depth.

[0026] In a further embodiment, it is conceivable that at least one corresponding stop surface is arranged between the connection points and the bolt, and that the stop surface is arranged orthogonally to the inclined surfaces. This design allows the frame to be easily assembled after the individual parts have been manufactured, making the frame cost-effective to produce. It also enables a visually appealing, flush finish between the bolt and the frame. Furthermore, the bolt's position relative to the frame is completely fixed by positive locking when the frame is fully assembled.

[0027] In a preferred embodiment, the stop surface is a side face of a wedge. A wedge is a stable element that provides sufficient resistance to the bolt and, in particular, exhibits the necessary stability during assembly. The wedge is arranged on one element, the connection point or the bolt, while the other element, the bolt or the connection point, has a corresponding recess.

[0028] In a preferred embodiment, a back surface of the wedge is arranged adjacent to one of the inclined surfaces in the same plane. This means that the inclined surface and the back surface of the wedge are flush with each other. This results in a particularly stable design that is also easy to manufacture. The back surface and the inclined surface can be offset from each other in the same plane. This means that the non-flush edges of the back surface and the inclined surface do not merge into one another.

[0029] In a preferred embodiment, the back surface is arranged at an angle between 10° and 80° with respect to the frame. Particularly preferably, the angle is at least 20°, 30°, 40°, 50°, 60°, 70°, or 80° and / or at most 80°, 70°, 60°, 50°, 40°, 30°, or 20°. Most preferably, the angle of the back surface and the angle of one of the inclined surfaces with respect to the frame are equal.

[0030] Furthermore, it is conceivable that a step surface is arranged in the depth adjacent to the sloping surfaces. The step surface is arranged correspondingly to the rail and frame. The step surface allows the rail to be flush with the frame. It is particularly preferred that the step surface is arranged on the inside, i.e., on the inner side of the frame. It is even more preferred that the step surface is orthogonal to the surface plane of the frame. It is even more preferred that the step surface is arranged parallel to the frame.

[0031] In one embodiment, it is conceivable that the first area is arranged at a depth offset from the second area, with an offset surface arranged at an angle to the step surface to bridge the offset. Preferably, the angle between the step surface and the offset surface is in a range between 90° and 170°. Particularly preferably, the angle between the step surface and the offset surface is at least 100°, 110°, 120°, 130°, 140°, 150°, or 160° and / or at most 160°, 150°, 140°, 130°, 110°, or 100°. The most preferred angle is 90° between the step surface and the offset surface.

[0032] The offset surface is designed to correspond to the rail and frame. In this way, a visually appealing transition between the first and second areas can be created.

[0033] In a further development of the invention, it is conceivable that at least one step is arranged in the second circumferential rebate. Preferably, 2, 3, 4, 5, 6, 7, 8, 9, 10 or more steps are arranged, whereby the steps can be identical or different in design. The second circumferential rebate serves to support a sash. The arrangement of at least one step increases the airflow between the interior and exterior. This can, on the one hand, improve the insulation of the frame and, on the other hand, make it more difficult to unintentionally breach the frame from the outside.

[0034] Furthermore, it is conceivable that the bar and the connection points are joined by means of an adhesive bond and / or a pin connection. This further increases the stability of the frame. The pins are particularly preferably arranged in a connection surface described elsewhere and / or in the inclined surfaces. Glue is also preferably used as the adhesive for the bond.

[0035] It is assumed that the definitions and / or explanations of the above-mentioned terms and the advantages described therein apply to all aspects described below in this description, unless otherwise stated.

[0036] According to the invention, a window comprising a frame described elsewhere is further proposed. The window is particularly preferably a casement window or a sliding window, especially a lift-and-slide window.

[0037] According to the invention, a door comprising a frame described elsewhere is further proposed. Preferably, the door is a hinged door or a sliding door, in particular a lift-and-slide door. The advantages described in connection with the frame can be achieved by means of the window and the door.

[0038] Further details, features, and advantages of the invention will become apparent from the following description of the preferred embodiments in conjunction with the dependent claims. The respective features can be implemented individually or in combination with one another. The invention is not limited to the embodiments. One embodiment is shown schematically in the figures. Identical reference numerals in the individual figures denote identical or functionally equivalent elements, or elements that correspond to one another with respect to their function.

[0039] Specifically, we show: Fig. Fig. 1: a first embodiment of a frame according to the invention; and Fig. 2: a second embodiment of a frame according to the invention.

[0040] Fig. 1A bis Fig. 1D Each figure shows a section of different views of a first embodiment of a frame according to the invention, in which the sash is arranged on the left and the panel, which can in particular be designed as fixed glazing, is arranged on the right. The frame comprises a surround 1 and a transom 2. The transom 2 is in the Fig. 1B and Fig. 1C shown spaced away from frame 1, so that the connection point 3 of frame 1 is visible. In Fig. 1D The bar is shown in isolation. A first circumferential fold 4 is arranged on frame 1 and bar 2. This is in the Fig. 1B bis Fig. 1D Each one is arranged on the side of the frame facing away from the viewer. Fig. 1A The first circumferential fold 4 is shown on the side facing the viewer. On the side opposite the frame, that is, in the Fig. 1B bis Fig. 1D On the side facing the viewer, a second circumferential rebate 5 is arranged. A panel (not shown) is attached to the first circumferential rebate 4, and a sash (not shown) is attached to the second circumferential rebate 5. Two inclined surfaces 6 are arranged on the transom 2 and at the connection point 3 of the frame 1. The inclined surfaces 6 are arranged such that they abut each other when the transom 2 is connected to the frame 1, i.e., they correspond to each other. A connecting surface 7 is arranged between each of the inclined surfaces 6, so that the inclined surfaces 6 and the connecting surface 7 form a trapezoid on the transom 2 and a corresponding trapezoidal recess on the frame 1. The connecting surface 7 runs parallel to the frame 1. On the transom 2, the connecting surface 7 forms the end face of the transom 2. The width of the inclined surfaces 6 and the connecting surface 7 is approximately 70% of the transom 2 and 70% of the transom 2, respectively.The frame 1 extends in a depth direction. The depth runs from the inside to the outside and is orthogonal to a plane spanned by the frame. In . Fig. 1B and Fig. 1C The inside of the frame is shown and in Fig. 1A the outside of the frame. Adjacent to the inclined surfaces 6 and the connecting surface 7 in depth, a wedge 8 is arranged on the frame 1. The bar 2 has a wedge-shaped recess corresponding to the wedge 8, which is located in the Figuren 1A und 1B The wedge 8 has a side surface that acts as a stop surface 9. Furthermore, the wedge 8 has a back surface 10 that fits into the frame 1. Fig. 1B and Fig. 1C The inclined surface 6 shown on the right transitions. The design with the inclined surfaces 6, the connecting surfaces 7 and the wedge 8 creates a resting position for the bar 2 on the frame 1, which prevents the bar 2 from shifting relative to the frame 1.

[0041] This creates a stable connection between frame 1 and transom 2, which can simultaneously be designed to be slim due to the alternating arrangement of the first circumferential rebate 4 and the second circumferential rebate 5. Next to the wedge 8, a shoulder surface 11 is arranged, which is recessed compared to the connecting surface 7 on frame 1. Correspondingly, the shoulder surface on transom 2 is positioned higher. The connection point 3 forms a plane with the remaining part of frame 1, creating an offset between the first circumferential rebate 4 and the second circumferential rebate 5. To bridge this offset, transom 2 and frame 1 comprise an offset surface 12, which is perpendicular to the shoulder surface 11. To create the most stable and durable connection possible between frame 1 and transom, pins 14 are arranged in the connecting surface to form a pin joint.To strengthen the pin connection, an adhesive can be applied to the corresponding surfaces.

[0042] Fig. 2A bis Fig. 2C Each shows a section of different views of a second embodiment of a frame according to the invention, in which the sash is arranged at the top and the panel, which can be designed in particular as fixed glazing, is arranged at the bottom. Fig. 2A Figure 1 shows a section of a view of a second embodiment of a frame according to the invention, comprising a frame 1 and a bar 2, from the outside. A first circumferential rebate 4 is arranged on the frame, and a second circumferential rebate 5 is arranged on the opposite side at a different depth. This arrangement of the rebates 4 and 5 allows the bar 2 to be designed more slenderly. The bar 2 and the frame 1 are connected to each other at a joint 3 of the frame 2. Fig. 2B Figure 1 shows a section of a perspective view of the frame 1 and the bolt 2 of the second embodiment of the frame according to the invention, from the inside, with the frame 1 and bolt 2 spaced apart from each other. Two inclined surfaces 6, connected by a connecting surface 7, are arranged on the frame 1 and the bolt 2. A wedge 8 is arranged laterally to the side of the inclined surfaces 6, which are rotated along a depth axis. The wedge 8 has a stop surface 9 for the bolt 2. In contrast to the first embodiment, the back surface 10 of the wedge 8 is narrower. Furthermore, a rounded transition area is formed between the inclined surfaces 6 and the connecting surface 7. The back surface 10 of the wedge 8 transitions into a shoulder surface 11, which is recessed relative to the connecting surface 7.An offset surface 12, perpendicular to the heel surface 11, bridges the height between the heel surface 11 and the upper part of the first circumferential rebate 4. The second circumferential rebate 5 is formed with a step 14. Furthermore, the bar 2 and the frame 1 are connected by means of pins 14. Fig. 2C Figure 1 shows a section of a perspective view of the frame 1 and the bolt 2 of the second embodiment of the frame according to the invention, from the outside, with the bolt 2 being offset from the frame 1. The bolt 2 is designed correspondingly to the frame 1 and also comprises inclined surfaces 6 that are orthogonal to a plane of the frame. The inclined surfaces 6 are connected by a connecting surface 7. Next to the connecting surface 7, the counterpart to the wedge 8 is designed as a recess with a back surface 10, the back surface 10 transitioning into one of the inclined surfaces 6. The bolt 2 also has a stop surface 9. The shoulder surface 11, corresponding to the frame 1, projects from the bolt 2. Bezugszeichenliste
