EP3085875B1 - Device, actually a door or a window, for closing an opening - Google Patents

Description

The present invention relates to a device for closing an opening, namely a door or a window, with a door or window leaf and at least one stop profile which interacts with the door or window leaf in a largely form-fitting manner when the door or window is closed. Numerous devices for closing an opening, in particular doors or windows, are known in the prior art. The door leaf of a door or the window leaf of a window when closed usually hits against a stop, which can optionally be provided with a seal. The stop itself is usually provided or formed by the door or window frame or the door or window frame. Usually, the narrow surface of the door or window leaf connecting the side edges of the side surfaces of the door or window leaf and, accordingly, the surface of the stop for the same is formed by a single surface running perpendicular to the side surfaces or with a step-like projection or recess.

The disadvantage of the known doors or windows is that at least the stop protrudes towards the masonry, especially when a door frame of a door is mounted within a hallway passage, and thus reduces the clear passage.

In addition, the sealing of the known doors or windows is sometimes problematic, especially in the case of doors or windows that close tightly in accordance with building regulations, as they are intended in particular for the purposes of fire protection and/or smoke protection, in particular in the case of fire protection doors or fire protection windows and/or smoke protection doors or.

Smoke protection windows, which are designed to prevent not only the spread of fire and/or smoke, but also sometimes also an inadmissible transfer of heat, depending on their fire resistance period. For example, in the case of swing doors in which a narrow surface connecting the side edges of the side surfaces of the door leaf is curved or rounded, sealing in the area of the curved or rounded narrow surface of the door leaf is usually not possible or only possible with brushes. Such brushes are mounted in the area of the rounded narrow surface of the door leaf, for example on the rounded narrow surface of the door leaf or on the stop, but do not enable a clean seal that is particularly sufficient for fire protection purposes.

The NL 6406521 A discloses a watertight and airtight window frame made of wood or metal, comprising correctly fitted grooves and corresponding brass, which do not fit exactly together but carry water and form double-acting, wind-dampening seats for changing direction.

The DE 1 659 734 A discloses a plastic window made of a frame and a sash frame, the frame and the sash frame being constructed from identical, extruded plastic hollow profiles and the profiles consisting of an angle section with a connected stop flange and an arch section connecting these elements, the arch section having an additional stop bar running in the longitudinal direction of the profile and when the window is closed, a labyrinth sealing chamber is formed between the frame and the sash frame.

The Fig. 1a to Fig. 3b each show a door designed for fire protection purposes with a door leaf 1 and a stop profile 2 which interacts with the door leaf 1 in a largely form-fitting manner when the door is closed and which is at least partially arranged in the wall W of a reveal. In Fig. 1a to Fig. 3b the door leaf 1 is shown graphically as a wood or wood-based door leaf without a pane. However, in an advantageous embodiment of the invention, the door leaf 1 can also have at least one fire protection pane, in particular in accordance with DIN 4102 or DIN EN 13501, which is made up of glass panes with a fire protection layer arranged in between. Alternatively, the door leaf 1 can also consist of such a fire protection pane, in which the narrow surface 7 connecting the side edges 5 and 6 of the side surfaces 3 and 4 of the door leaf 1 is designed or set up according to the invention, for example by a profile element. The stop profile 2 is preferably made of solid wood.

In the case of the door leaf 1, the narrow surface 7 of the door leaf 1 connecting the side edges 5 and 6 of the side surfaces 3 and 4 of the door leaf 1 consists of three partial surfaces or surfaces 7a, 7b and 7c. The surfaces 7a and 7b enclose an angle α and the surfaces 7b and 7c enclose an angle ε. The surface 7a of the narrow surface 7 adjoining the side edge 5 of the side surface 3 of the door leaf 1 and the side surface 3 of the door leaf 1 form an obtuse angle β.

In the exemplary embodiments Fig. 1a , Fig. 1b and Fig. 2 The surface 7c of the narrow surface 7 adjoining the side edge 6 of the side surface 4 of the door leaf 1 runs perpendicular to the side surfaces 3 and 4 of the door leaf 1. In the exemplary embodiment Fig. 3a and Fig. 3b The surface 7c of the narrow surface 7 adjoining the side edge 6 of the side surface 4 of the door leaf 1 describes a circular arc section 7c, in the present case for example with a Radius R of 60 mm. The pivot point D of a tenon band 13 forms the center of the radius R.

The surface 8 of the stop profile 2, which essentially interacts positively with the door leaf 1 in the closed state of the door, which is opposite the narrow surface 7 of the door leaf 1 in the closed state of the door, shows in the exemplary embodiments Fig. 1a to Fig. 3b three partial surfaces or surfaces 8a, 8b and 8c, which lie opposite the narrow surface 7 of the door leaf 1 corresponding to the partial surfaces 7a, 7b and 7c. At least the surface 7a of the narrow surface 7 of the door leaf 1 and the surface 8a of the stop profile run essentially parallel to one another. In the case of the stop profile 2, the surfaces 8a and 8b form an angle χ and the surfaces 8b and 8c form an angle φ. The partial surface 8a of the surface 8 of the stop profile 2, which is at least partially arranged in the wall of a reveal, forms an acute angle δ with a plane 9 which runs parallel to one of the side surfaces 3 and 4 of the door leaf 1 when the door is closed.

In the exemplary embodiments Fig. 1a , Fig. 1b and Fig. 2 the door leaf 1 and the stop profile 2 each have at least one recess for a receiving body 12a or 12b of a band 11 for a concealed arrangement between the door leaf 1 and the stop profile 2. The exemplary embodiment according to Fig. 1a and Fig. 1b differs from the exemplary embodiment Fig. 2 by arranging the stop profile 2 in the wall W of a reveal. In the exemplary embodiment according to Fig. 2 the wall W is designed to be less voluminous and/or the stop profile 2 is arranged closer to or in the edge region of the wall, which runs parallel to one of the side surfaces 3 and 4 of the door leaf 1 when the door is closed. The arrangement according to Fig. 2 allows for a comparison to the arrangement Fig. 1a and Fig. 1b further opening of the door, since the door leaf 1 of the door can be further rotated or pivoted around the pivot point D (in Fig.1a and Fig. 1b as well as Fig. 2 shown by dashed lines on the door leaf 1).

In the exemplary embodiments Fig. 1a , 1b and Fig. 2 the angles preferably have the following values or value ranges: angle Value α from 75° to 105°; preferably from 85° to 95°; particularly preferably 90° β greater than 90° to less than 180°; preferably from 100° to 120°; particularly preferably 111°; χ from 75° to 105°; preferably from 85° to 95°; particularly preferably 90°; δ from greater than 0° to less than 90°; preferably from 60° to 80°; particularly preferably 69°.

The Fig. 4 , Fig. 5 and Fig. 6 each show an exemplary embodiment of a door designed for fire protection purposes with a door leaf 1 and a stop profile 2 which interacts with the door leaf 1 in a largely form-fitting manner when the door is closed and which is at least partially arranged in the wall W of a reveal. In Fig. 4 , Fig. 5 and Fig. 6 the door leaf 1 is shown graphically as a wooden or wood-based door leaf without a pane. However, in an advantageous embodiment of the invention, the door leaf 1 can also have at least one fire protection pane, in particular in accordance with DIN 4102 or DIN EN 13501, which is made up of glass panes with a fire protection layer arranged in between. Alternatively, the door leaf 1 can also consist of such a fire protection pane, in which the narrow surface 7 connecting the side edges 5 and 6 of the side surfaces 3 and 4 of the door leaf 1 is designed or set up according to the invention, for example by a profile element. The stop profile 2 is preferably made of solid wood.

For door leaf 1 after Fig. 4 The narrow surface 7 of the door leaf 1 connecting the side edges 5 and 6 of the side surfaces 3 and 4 of the door leaf 1 consists of three partial surfaces or surfaces 7a, 7b and 7c. The surfaces 7a and 7b enclose an angle α and the surfaces 7b and 7c enclose an angle ε. The surface 7a of the narrow surface 7 adjoining the side edge 5 of the side surface 3 of the door leaf 1 and the side surface 3 of the door leaf 1 form an obtuse angle β. The surface 7c of the narrow surface 7 adjoining the side edge 6 of the side surface 4 of the door leaf 1 assumes an obtuse angle to the side surface 4. The door leaf 1 is provided with a pin hinge 13 and can be pivoted about its pivot point D. The surface 8 of the stop profile 2, which is opposite the narrow surface 7 of the door leaf 1 in the closed state of the door and which interacts essentially positively with the door leaf 1 in the closed state of the door, has three partial surfaces or surfaces 8a, 8b and 8c, which correspond to the partial surfaces 7a, 7b and 7c lie opposite the narrow surface 7 of the door leaf 1. At least the surface 7a of the narrow surface 7 of the door leaf 1 and the surface 8a of the stop profile run essentially parallel to one another. In the case of the stop profile 2, the surfaces 8a and 8b form an angle χ and the surfaces 8b and 8c form an angle φ. The partial surface 8a of the surface 8 of the stop profile 2, which is at least partially arranged in the wall of a reveal, forms an acute angle δ with a plane 9 which runs parallel to one of the side surfaces 3 and 4 of the door leaf 1 when the door is closed.

For door leaf 1 after Fig. 5 The narrow surface 7 of the door leaf 1 connecting the side edges 5 and 6 of the side surfaces 3 and 4 of the door leaf 1 consists of five partial surfaces or surfaces (not explicitly shown here for reasons of clarity). The door leaf 1 is provided with a tenon hinge 13 and around its pivot point D pivotable. The surface 8 of the stop profile 2, which is opposite the narrow surface 7 of the door leaf 1 when the door is closed, and which interacts essentially positively with the door leaf 1 in the closed state of the door, also has five partial surfaces or surfaces which correspond to the partial surfaces of the narrow surface 7 of the door leaf 1.

For door leaf 1 after Fig. 6 The narrow surface 7 of the door leaf 1 connecting the side edges 5 and 6 of the side surfaces 3 and 4 of the door leaf 1 consists of four partial surfaces or surfaces (not explicitly shown here for reasons of clarity). The door leaf 1 is provided with a tenon hinge 13 and around its pivot point D pivotable. The surface 8 of the stop profile 2, which is opposite the narrow surface 7 of the door leaf 1 in the closed state of the door and which interacts essentially positively with the door leaf 1 in the closed state of the door, also has four partial surfaces or surfaces which correspond to the partial surfaces of the narrow surface 7 of the door leaf 1.
