Description

description

The invention relates to a wall opening of a wall of a building, the wall opening being provided with a frame and a pivotable wing and wherein the frame and the pivotable wing are arranged on one side of the wall essentially flush with the wall surface. The term “pivotable wing” typically means a pivotable door leaf, but can also mean a pivotable window wing. The invention further relates to a hinge which can advantageously be used between the frame and the pivotable wing.

EP 1079057 A2 shows a construction for a swing door in which the frame (the frame part of the door rigidly attached to the wall opening) and the closed door leaf (the pivotable part of the door) are aligned flush with one side of the wall. In this typical case, the door leaf is designed with a blunt edge instead of a folded edge. This means that the end faces of the door leaf are designed as simple flat surfaces that are aligned normal to the plane of the door leaf. If the door leaf is to be flush with the frame, the arrangement of the hinges is easier with a blunt edge than with a folded edge. Disadvantages of the blunt edge are, however, that the soundproofing is worse - because there is only one sealing level instead of two sealing levels and that when the door is closed, the latch of the door lock opens on a surface area of the frame which is visible when the door is closed. This impact area becomes visually noticeable over time and leads to a messy or defective appearance.

DE 1683419 A1 shows a design for a door with a door leaf arranged flush with the wall, the door leaf having a folded edge. This means that the end faces of the door leaf are designed in a step-like manner, the normal to the plane of the door leaf being aligned between two surfaces

WOE is an area that is parallel to the plane of the door leaf. To match the end face of the door leaf, the sides of the lateral surface of the lateral surface of the profile pieces forming the frame, which face the wall opening, are also composed of partial areas lined up in a step-like manner. From the side from which the closing pivoting movement of the pivoting door takes place, a partial surface that is oriented normal to the wall plane and can be designated as the outer folding surface is followed by a second partial surface that is parallel to the wall plane and can be designated as the outer sealing surface; this is followed by a partial surface that is oriented normal to the wall plane and can be designated as the inner rebate surface, and then a partial surface that is parallel to the wall plane and can be designated as the inner sealing surface. The trap opening is located on the inner fold surface, which eliminates the optical disadvantage previously discussed with the aid of the blunt edge. On the frame side, the hinge is attached to the outer rebate surface; So that it goes well, the outer fold surface is made unusually wide. It is almost imperative to use a hinge in which the swivel bearing is immovable in front of the surface of the door leaf and thus protrudes from the plane on which one wall side, the frame and the door leaf lie flush.

The object on which the invention is based is to improve the construction known from DE 1683419 Al for a flush-mounted frame with a flush-mounted pivotable wing with a folded edge so that door leaves with a narrower outer rebate surface can also be used without problems as a pivotable wing. This means that door leaves with a so-called standard rebate can be used. In the case of door leaves of this type, the outer rebate surface - which usually projects above the frame - is only about 16 mm wide; Such door leaves are mass-produced and as such are much easier and cheaper to obtain than door leaves with a wider outer rebate surface or with a blunt edge.

To solve the problem, the combination of features known from DE 1683419 A1 is used, according to which the pivotable wing has a folded edge and, correspondingly, the boundary surface of the frame facing the wall opening has an outer and an inner rebate surface and an outer and an inner sealing surface, the trap opening is on the inner fold surface. As an improvement in accordance with the invention, it is proposed that the anchoring of the hinges on the frame and on the pivotable sash be predominantly provided in that volume area which adjoins the inner rebate surface in the direction parallel to the wall plane.

In addition to the advantage that door leaves with standard rebate can be used, there are other significant advantages compared to the previously known construction that the stability is improved and that it is easier even when using hidden hinges when closed, wall paneling - typically with plasterboard - up to the edge of the frame profile at which the outer rebate surface ends on the outside without interrupting locally on hinge parts and then having to fill.

As can be seen from the drawings, the fastening of the hinges in this regard is surprisingly easy to implement.

1, the wall 1 is pierced by a wall opening 2, the edge of which is bordered by a frame 3, on which a pivotable wing 4 is rotatably supported by hinges 5.

The frame 3 shown is formed from straight sheet steel profile pieces, which in the example shown in FIG. 1 are each made up of two partial profiles 6, 7, which are aligned parallel to one another and are typically connected to one another by spot welding or longitudinal seam welding.

The lateral surface facing the wall opening 2 of the steel sheet profile pieces forming the frame 3 has four essentially flat partial surfaces, which follow one another like steps and from the side from which the closing pivoting movement of the pivotable wing 4 takes place, narrow the wall opening 2 in steps. A partial surface that is oriented normal to the wall plane and is referred to as the outer rebate surface Θ is followed by a second partial surface that is parallel to the wall plane and is referred to as the outer sealing surface 9. This is followed again by a partial surface oriented normally to the wall plane, referred to as the inner rebate surface 10, and then by a partial surface lying parallel to the wall plane, referred to as the inner sealing surface 11.

It is advisable to attach sealing profiles 12 to the sealing surfaces 9, 11. When the pivotable wing is closed, the pivotable wing 4 comes to rest against the sealing profiles by means of a movement which is oriented normally to the sealing surfaces.

The latch of the door lock attached to the pivotable wing 4 engages in the latching movement of the pivotable wing 4 into a latch opening 13 which penetrates the inner rebate surface 10. The inner fold surface 10 preferably has a so-called impact nose 14, which is formed by the inner fold surface 10 being widened beyond the plane of the outer sealing surface 9, so that it intersects the plane of the outer sealing surface 9. Due to this projecting nose 14, this is on the outside

WOE outer sealing surface 9 located sealing profile 12 protected from damage by the latch of the door lock.

The hinges 5 are fastened to the frame 3 as well as to the pivotable wing 4 in a volume area which is adjacent to the inner rebate surface 10 in the direction parallel to the plane of the wall 1. To match, the outer sealing surface 9 and the inner rebate surface 10 are broken through openings for parts of the hinges or fastening screws. The outer fold surface 8 and also the fold surface opposite this on the pivotable wing 4 need not be broken by any part of the hinges. This makes it easy to see the visible surface of the pivotable wing 4 and the outermost planking 15 of the wall 1 without a local opening. the profile wall of the frame 3 delimiting the outer fold surface 8. This favors an even appearance and quick and easy installation.

According to a very advantageous further development which can be seen in FIG. 1, the wall 1 in the area of the wall opening 2 has several layers of planking 15, and the steel profiles forming the frame 3 have profile walls which protrude between the layers of the planking 15 and screws 16 run through the planking 15 and these profile walls. This achieves good stability and the crack formation in the planking 15, which is otherwise feared at the frame area, is very well prevented.

In the example according to FIG. 1, hinges 5 are used in which the pivot axis lies immovably in front of the surface of the pivotable wing 4 and thus protrudes from the plane on which wall 1, frame 3 and closed pivotable wing 4 are flush. The construction is stable and simple. Even if the appearance is often quite accepted, it is disadvantageous that the rollers of the hinges 5 are visible even when the pivotable wing is closed and protrude from the wall 1.

2 and 3 show designs according to the invention in which a so-called hidden hinge 17 is used. This hinge 17 is not visible when the pivotable wing 4 is closed, since in the direction normal to the plane of the wall 1 it does not protrude from the visible edges of the end face of the pivotable wing, let alone protrude beyond it.

On the frame side, the hinge 17 is anchored to the inner rebate surface 10 by means of screws 18. On the wing side, the hinge 17 is anchored via a pot-like housing 19, which is inserted into a cutout on the end face of the pivotable wing 4. The inner and outer visible surface of the pivotable wing 4 (the two large surfaces of the pivotable wing 4 lying parallel to the level of the pivotable wing) are not affected by this milling.

The hinge 17 shown in FIGS. 2 and 3 can advantageously be used on many types of pivotable leaves of doors or windows with hidden hinges, that is to say not only pivotable leaves according to the present invention. On pivotable wings n according to the present invention, it is particularly advantageous because the advantage is very good that it is quite narrow in the closed state in the direction normal to the wall plane, and yet during the pivoting opening movement of the pivotable wing 4 in the Level of the wall 1 normal direction relative to the anchoring on the frame 3 moves very far.

All of the pivot axes mentioned in the following description of the hinge 17 are aligned parallel to one another and aligned normal to the plane which is parallel to the opening or closing pivoting movement of the pivotable wing 4.

The hinge 17 has an anchoring plate 20 which is anchored rigidly to the inner rabbet surface 10 by means of screws 18

WOE is. On the anchoring plate 20, two levers 21, 22 are pivotally attached at a distance from one another. The free ends of the levers 21, 22 are pivotally mounted at a distance from one another on a further plate, referred to as a '' sliding plate 23, in such a way that the two plates 20, 23 and the two levers 21, 22 are shown by the lines between their two Spanning the pivot axes a conceived square 24, which may have the shape of a parallelogram. (Indicated in dotted lines in FIG. 3.)

The displacement plate 23 has an extension 25 which projects with a first longitudinal region in the direction of the connecting line between the two pivot axes of the displacement plate 23 to the side into which the pivotable wing 4 is to be displaced during its opening pivoting movement. A second longitudinal region of the extension 25 adjoining the first longitudinal region is curved away from the wall opening 2 and, with its free end region, can be pivoted with the at a first pivot axis 26. connected to the pivotable wing 4 rigidly anchored pot-like housing 19.

A lever 22 from the aforementioned group of the two levers 21, 22 also has an extension, at the free end of which a third lever 27 is pivotally mounted with its first end. The second end of the third lever 27 is pivotally connected to the housing 19 anchored on the pivotable wing 4 via a second pivot axis 28. The two pivot axes 26, 28 on the housing 19 are spaced apart.

The above-mentioned arrangement of pivot axes and levers means that when the pivotable wing 4 is pivoted relative to the wall 1, it is also forcibly displaced translationally relative to the wall 1, especially normal to the wall 1. Extent and directional components of the translational displacement can be adjusted to each other by positioning the individual pivot axes. Optimization goals in this regard7

Positions are to achieve a large translational displacement in the direction normal to wall 1 with small installation dimensions and to keep the translational displacement in the directions parallel to wall 1 small. As a result, the pivotable sash 4 should be in front of the wall 1 when it is open at 180® without striking it, and should not collide with boundary surfaces of the wall opening 2 during the opening and closing movement. In this context, advantageous dimensions can be found quite simply by experimenting with a CAD program as part of professional action, as it was successfully tested several times during the development of the hinge and confirmed by subsequent prototype construction. It is therefore not necessary to go into details here.

Due to the design described, the hinge 17 can be built quite small in relation to its translational displacement range. It is also advantageous that the movements of the individual parts, which are guided against one another, are exclusively pivoting movements, which achieves greater robustness than in the case of movements guided in translation.

It should be clarified that the frame does not necessarily have to be formed from sheet steel for a construction according to the invention. For example, extruded aluminum can also be used.

It should also be clarified that the partial lateral surfaces of the frame profiles, which are referred to as sealing surfaces 9, 11, do not necessarily have to carry a sealing profile or have to act in a sealing manner. The term sealing surface here only means that it is quite possible to use these surfaces in this way.
