Description

[0001] The present invention relates to a double-leaf door, a double-leaf window or a double-leaf French window, with a standing or inactive leaf with a narrow surface connecting the side edges of the side surfaces of the door leaf or window sash of the standing leaf, wherein the side edges of the side surfaces of the door leaf or window sash of the inactive leaf are spaced apart from one another by a distance in the horizontal direction of extension of the door leaf or window sash of the standing leaf, and a walking or aisle leaf with a narrow surface connecting the side edges of the side surfaces of the door leaf or window sash of the moving leaf, wherein the side edges of the side surfaces of the door leaf or window sash of the moving leaf are spaced apart from one another by a distance in the horizontal direction of extension of the door leaf or window sash of the moving leaf, wherein in the closed state of the door orof the window, the narrow surface of the inactive leaf and the narrow surface of the active leaf face each other.

[0002] Doors and windows for closing openings are known in the state of the art in numerous designs and for a wide variety of applications. Doors and windows serve as access and closure points in buildings and must also fulfill other functions or properties depending on their application, particularly in the case of tightly closing doors and windows according to building regulations, such as those intended specifically for fire and / or smoke protection purposes. Thus, fire doors and / or smoke doors, in particular, are designed, depending on their fire resistance rating, not only to prevent the spread of fire and / or smoke, but sometimes also to prevent the impermissible transfer of heat.

[0003] In many public buildings, such as schools, theaters, museums, and / or similar assembly halls, double-leaf doors are often required, partly to accommodate larger crowds and partly for historical and / or design reasons. Such doors are often located in necessary escape routes, particularly those intended to rescue people in the event of danger. For example, German building regulations require that these doors be easy to open with one hand in the event of danger, such as fire and / or smoke.

[0004] With double-leaf doors, especially narrow double-leaf doors, it is problematic that opening the door in an emergency situation can result in the two leaves (inactive leaf and active leaf) jamming or forcing in the area of ​​the center stop if an attempt is made to open the door via the inactive leaf (so-called panic situation). The door itself cannot then be opened any further due to the jamming or forcing of the inactive leaf and active leaf in the area of ​​the center stop of the two leaves. Figuren 1a und 1b, 2a und 2b , 3a and 3b, 4a und 4b , 5a und 5b , as well as 6a und 6b Prior art examples of double-leaf doors are shown, in which the inactive leaf and the active leaf jam in the center stop area when the door is opened over the inactive leaf and therefore cannot be opened. The same applies to double-leaf windows or double-leaf French doors.

[0005] In order to prevent jamming or forcing of the inactive leaf and the active leaf of a double-leaf door when the door is opened via the inactive leaf, the state of the art has so far provided, for example, so-called catch flaps. A catch flap generally ensures that when a double-leaf door is opened via the inactive leaf, i.e., in a so-called panic situation, the active leaf is pushed in front of the inactive leaf to prevent jamming or forcing. Often, the active leaf is carried by the catch flap at least until the beginning of the effective range of a door sequence selector. Such catch flaps are visually unappealing and often undesirable from an architectural point of view, particularly for historical and / or design reasons. Fig. 7a bis 7f An embodiment of a double-leaf door with a carrier flap, which is already known in the prior art, is shown.

[0006] Another prior art approach to preventing the inactive leaf and active leaf of a double-leaf door from jamming or forcing when the door is opened via the inactive leaf, i.e., in a so-called panic situation, involves increasing the horizontal distance known as the central gap between the narrow surfaces connecting the side edges of the side surfaces of the door leaf of the inactive leaf and the active leaf. Such an enlargement of the central gap is generally visually unappealing and often undesirable from an architectural point of view. Furthermore, an enlargement of the central gap generally leads to sealing problems, which is particularly disadvantageous for so-called fire and / or smoke protection doors and can sometimes limit their functionality or render them unusable.

[0007] Double-leaf swing doors or swinging doors, which were previously used in the state of the art, especially for escape routes, are also problematic. In addition to the sealing problems typically associated with double-leaf swing doors or swinging doors, a disadvantage is that opened doors automatically close again, and when slammed shut, the door leaves tend to slam through to the other side of the opening. Such slamming of the door leaves to the other side of the opening poses a significant risk of injury.

[0008] Against this background, the object of the present invention is to prevent the passive leaf and active leaf of a double-leaf door or double-leaf window from jamming or forcing together, in particular when the door is opened in a so-called panic situation, i.e. when the door is opened via the passive leaf. In particular, the use of a so-called follower flap is to be avoided. Furthermore, sealing problems are to be avoided, particularly in the area of ​​the so-called center stop of the two leaves, especially with regard to fire, smoke and / or noise, so that fire protection or smoke protection purposes can be met in accordance with the requirements of DIN 4102 or DIN EN 13501, DIN EN 16034 or DIN 18095 or DIN EN 1364-1+3. In particular, a clean seal that is sufficient for fire protection and / or smoke protection purposes is to be achieved.

[0009] To achieve this objective, the present invention provides a double-leaf door, a double-leaf window or a double-leaf French window, with a stationary or inactive leaf with a narrow surface connecting the side edges of the side surfaces of the door leaf or window sash of the stationary leaf, wherein the side edges of the side surfaces of the door leaf or window sash of the inactive leaf are spaced apart from one another by a distance in the horizontal direction of extension of the door leaf or window sash of the inactive leaf, and a moving or active leaf with a narrow surface connecting the side edges of the side surfaces of the door leaf or window sash of the active leaf, wherein the side edges of the side surfaces of the door leaf or window sash of the active leaf are spaced apart from one another by a distance in the horizontal direction of extension of the door leaf or window sash of the active leaf, wherein in the closed state of the door or window the narrow surface of the inactive leaf and the narrow surface of the active leaf face one another, which orwhich is characterized in that the narrow surface of the inactive leaf has or forms a slanted rebate and the narrow surface of the active leaf has or forms a round rebate, wherein the slanted rebate of the inactive leaf rests at least partially on the round rebate of the active leaf when the door or window is opened via the inactive leaf and the curve of the round rebate of the active leaf and the slope of the slanted rebate of the inactive leaf are designed such that the active leaf can be or is moved in the opening direction of the active leaf when the door or window is opened via the inactive leaf.

[0010] According to the invention, a combination of a slanted rebate on the inactive leaf and a rounded rebate on the active leaf of a double-leaf door, a double-leaf window or a double-leaf French window is provided. When the double-leaf door or double-leaf window is opened via the inactive leaf, the slope of the slanted rebate of the inactive leaf rests on the curve of the rounded rebate of the active leaf. The curve of the rounded rebate of the active leaf ensures that the slope of the slanted rebate of the inactive leaf pushes or moves the curve or the active leaf forward, i.e. in front of the inactive leaf, and no clamping or forcing occurs. Due to the rebate geometries according to the invention on the part of the two leaves of the double-leaf door or double-leaf window, the curve of the rounded rebate slides through the slope or ramp of the slanted rebate, so that the double-leaf door or double-leaf window can be opened further. According to the invention,In this respect, the diagonal rebate of the passive leaf can be used or utilized as a so-called sliding ramp for the active leaf. The present invention is based in particular on findings obtained through empirical tests which have shown that the jamming or forcing is based on a particular geometric feature of double-leaf doors or windows. The invention is based in particular on the finding that the narrower and thicker the leaves of the door or window are and the further the respective pivot point of the leaves lies outside the door or window surface or the door or window axis of the respective leaf, the more likely the passive leaf and active leaf will jam or forcing in the area of ​​the center stop. Furthermore, the distance or gap between the two leaves in the area of ​​the center stop has a major influence on the jamming or forcing of the leaves.The less gap there is in the area of ​​the center stop of the two leaves, the greater the tendency for the two leaves to jam or force when the door or window is opened via the inactive leaf.

[0011] Advantageously, the slope of the slanted rebate of the inactive leaf and the curve of the rounded rebate of the active leaf are coordinated in such a way that the door or window can be opened via the inactive leaf without jamming or strain. The inventive coordination of the slope of the slanted rebate of the inactive leaf and the curve of the rounded rebate of the active leaf is advantageously carried out depending on or taking into account the width and thickness of the two leaves of the door or window, the position or location of the respective pivot points of the leaves, and / or the distance or gap between the two leaves in the area of ​​their central stop. Advantageously, the curve of the rounded rebate of the active leaf is almost completely concealed or covered by the slope of the slanted rebate of the inactive leaf when the double-leaf door or double-leaf window is closed.From the outside, the slanted rebate of the passive leaf and the round rebate of the active leaf are therefore not or almost not visible when the door or window is closed.

[0012] A further advantageous embodiment of the invention provides that the narrow surface of the inactive leaf further comprises or forms a step rebate, to which the diagonal rebate of the inactive leaf adjoins, and the narrow surface of the active leaf further comprises or forms a step rebate, to which the round rebate of the active leaf adjoins, wherein the step rebate of the narrow surface of the inactive leaf and the step rebate of the narrow surface of the active leaf are preferably designed to complement one another. A combination of step rebate and diagonal rebate on the part of the inactive leaf and a combination of step rebate and round rebate on the part of the active leaf provided according to the invention allows for a further improvement of the design with regard to fire, smoke and / or noise, in particular for fire protection purposes or smoke protection purposes in accordance with the requirements of DIN 4102 or DIN EN 13501, DIN EN 16034 or DIN 18095 or DIN EN 1364-1+3.

[0013] A further advantageous embodiment of the invention provides that the narrow surface of the inactive leaf is at least partially provided with at least one sliding element, at least in the area of ​​the inclined rebate, and / or the narrow surface of the active leaf is at least partially provided with at least one sliding element, at least in the area of ​​the round rebate. Advantageously, the sliding element of the narrow surface of the inactive leaf and / or the sliding element of the narrow surface of the active leaf is a sliding surface made of an element with a smooth surface, preferably made of steel, non-ferrous metals (non-ferrous metals: all metals in the periodic table except iron, such as in particular copper, aluminum, zinc, nickel, lead, magnesium, gold and / or silver), ceramic, PTFE fabric, PTFE-FRP fabric or thermosets, or a sliding roller. According to the invention, the functioning of the double-leaf door or a double-leaf window is thus improved, in particular with regard to jamming orConstraining is further improved and in particular any abrasion on the narrow surface of the passive leaf and active leaf is avoided or reduced.

[0014] According to a further advantageous embodiment of the invention, the side surfaces of the door leaf or window sash of the inactive leaf are spaced from one another by a distance, preferably in a range of approximately 30 mm to approximately 120 mm, and the side surfaces of the door leaf or window sash of the active leaf are spaced from one another by a distance, preferably in a range of approximately 30 mm to approximately 120 mm. The door leaf or window sash of the inactive leaf and / or the active leaf advantageously has the following dimensions: a height h in a range from 1700 mm to 5000 mm, preferably in a range from 1900 mm to 4200 mm, a width b in a range from 400 mm to 3200 mm, preferably in a range from 400 mm to 2800 mm. A further advantageous embodiment of the invention is characterized by a horizontal distance between the side edges of the side surfaces of the door leaf orWindow sash of the passive leaf in a range of approximately 10 mm to approximately 70 mm, and / or by a horizontal distance of the side edges of the side surfaces of the door leaf or window sash of the active leaf in a range of approximately 10 mm to approximately 60 mm.

[0015] Advantageously, the narrow surface of the inactive leaf, preferably in the region of the rebate, is or can be provided at least partially with a sealing arrangement or sealing element running in the vertical direction of the door leaf or window sash of the inactive leaf, and / or the narrow surface of the active leaf, preferably in the region of the rebate, is or can be provided at least partially with a sealing arrangement or sealing element running in the vertical direction of the door leaf or window sash of the active leaf, wherein the sealing arrangement or sealing element of the narrow surface of the inactive leaf and the sealing arrangement or sealing element of the narrow surface of the active leaf are preferably designed to complement one another. Advantageously, the sealing arrangement or sealing element meets the requirements of DIN EN 1634-1+3 or DIN 18095.

[0016] A particularly advantageous embodiment of the invention provides that the sealing arrangement or the sealing element of the narrow surface of the passive leaf and / or the sealing arrangement or the sealing element of the narrow surface of the active leaf are equipped with a heat-absorbing material and / or with a material that intumescents in the event of a fire. Advantageously, the heat-absorbing material and / or the material that intumescents in the event of a fire meets the requirements of DIN EN 1634-1+3.

[0017] Advantageously, the door or window according to the invention is designed for the purposes of fire and / or smoke protection, and is preferably a fire door and / or a smoke door or a fire window and / or a smoke window, in particular according to DIN 4102 or DIN EN 13501, DIN EN 16034 or DIN 18095 or DIN EN 1634-1+3.

[0018] A further particularly advantageous embodiment of the invention is characterized in that the door leaf or window sash of the passive leaf and / or the door leaf or window sash of the active leaf has at least one fire protection pane or is made of a fire protection pane, wherein the fire protection pane preferably consists of a composite of at least two glass panes arranged parallel to one another, between which at least one fire protection layer is arranged, preferably made of a material that is intumescent in the event of a fire. Advantageously, the fire protection pane is designed such that it satisfies or fulfills DIN 4102 or DIN EN 13501. Such a fire protection pane suitable for smoke and / or fire protection purposes advantageously prevents the passage of fire and / or smoke from one fire compartment or room into another fire compartment or room.In the event of a fire, the fire protection layer between the parallel glass panes is activated, absorbing heat radiation and forming a highly effective insulating layer. Advantageously, the fire protection pane is designed using so-called waterglass technology or so-called gel technology. In a fire protection pane using waterglass technology, the fire protection layer consists of materials arranged between a plurality of glass panes, in particular materials containing an alkali silicate mass, which act as foaming agents and foam up in the event of a fire. In a fire protection pane using gel technology, the fire protection layer arranged between two glass panes, which is activated in the event of a fire, is made of gel-like materials, in particular organic polymers.A further advantageous embodiment of the invention provides that the at least two parallel glass panes of the fire protection pane are spaced apart from one another by means of a profile-like spacer forming an edge seal, which is preferably arranged between the at least two parallel glass panes of the fire protection pane and particularly preferably extends along the side edges of the fire protection pane. The edge seal of a fire protection pane according to the invention therefore has a spacer running around the edge. Such spacers are used particularly—but not exclusively—in fire protection panes using gel technology.

[0019] The pivot point or axis of rotation for the door leaf or window sash of the passive leaf and / or the door leaf or window sash of the active leaf is usually located outside the respective door leaf plane or window sash plane, for which purpose surface-mounted door or window hinges, in particular so-called construction hinges, are used, and / or within the door leaf plane or window sash plane, for which purpose pivot hinges or concealed hinges are also used.

[0034] The coordinated formation of the slope 4.1 of the sloped rebate 4 of the inactive leaf 2 and the curve 5.1 of the rounded rebate 5 of the active leaf 3 is advantageously carried out depending on or taking into account the width and thickness (AS2, AG2) of the two leaves 2 and 3 of the door 1 or the window, the position or location of the respective pivot points of the leaves 2 and 3 of the door axis or rotation axis of the respective leaf 2 or 3, and / or the distance or gap SM between the two leaves 2 and 3 in the area of ​​their center stop. The curve 5.1 of the rounded rebate 5 of the active leaf 3 is almost completely concealed or covered by the slope 4.1 of the sloped rebate 4 of the inactive leaf 2 when the double-leaf door 1 or the double-leaf window is closed. From the outside, the inclined rebate 4 of the passive leaf 2 and the round rebate 5 of the active leaf 3 are therefore not or almost not visible when the door 1 is closed.
