Definitions

  • the present invention relates on the one hand to a profile seal, in particular a so-called frame center seal, made of elastic material for sealing the rebate area between the outer and inner shell of a window frame accommodating a sash frame.
  • the invention also relates to a facade construction, in particular in the form of a window or door construction, using a corresponding profile seal.
  • Window or door constructions usually include a window frame and a casement frame that can be pivoted to the window frame.
  • the window frame is made up of vertical profiles and horizontal profiles.
  • the vertically and horizontally running profiles form corresponding facade cutouts, in which mostly glazing elements having sash frames can be pivoted.
  • the frame usually includes outer and inner frame profiles, preferably in the form of metal profiles, z. B. aluminum profiles, or plastic profiles that form the outer and inner shell of the window or door constructions and are connected via insulating webs located in between, made of thermally non-conductive or poorly conductive material.
  • Such insulating webs are preferably made of plastic. They prevent the formation of a cold bridge from the outer to the inner shell of the facade construction. In addition, they can prevent or at least reduce thermal convection within the cavity formed by the outer and inner shell, for example by means of separating webs extending into the cavity.
  • the DE 43 26 115 A1 describes a method for attaching a profile seal with fastening ribs and cover and sealing ribs to a combined wood-metal window, in which the seal is attached to the frame along a straight side of the frame with fastening ribs, using a tool with V -shaped miter cuts and two laterally offset relief cuts.
  • the sealing profile is in each case cut along its main direction of extent.
  • a sealing profile strip for sealing window panes in a window frame in which a V-shaped cut on the upper side and a lower cut as a narrow groove opposite are made to bend the sealing profile strip at the corners of the pane or frame. Both cuts are made deep enough to reach the top and bottom of a neutral zone, respectively. A hollow chamber running in the sealing profile strip is not affected by the upper V-shaped cut.
  • the sealing profile strip serves to seal a gap located between a window frame and an adjoining pane of glass.
  • a device for processing an elastic sealing profile strip for inner and outer sealing frames on window panes is known, by means of which a sealing profile strip sealing the window pane can be edited by introducing V-shaped notches and opposite cuts in the respective corner areas of the frame to be guaranteed by the sealing profile strip.
  • the incisions are also made parallel to the main direction of extent of the sealing profile strip.
  • the object of the present invention is to provide a new type of profile seal or facade construction which makes it possible to reduce the assembly costs in the manufacture of facade constructions.
  • the stop bar and/or the base body is/are designed as a solid material in the area of the stop bar means that when there is a V-shaped notch in the profile seal, frame-center seal, there are two continuous, i.e. uninterrupted, opposing cut surfaces the folding of the profile seal in the area of the V-shaped notch can be folded onto one another and, when assembled, ensure a particularly effective seal to the outside.
  • the generic profile seal has an L-shaped basic shape, ie the stop bar protrudes beyond the base body in the edge area or on the end area of the profile seal on the outside of the facade.
  • a V-shaped notch in the profile seal a continuous contact surface is created for possible bonding in this area.
  • the "base body 2 in the area of the stop bar 5" is the area of the base body that is below the stop bar and above the sealing foot 3 .
  • the elastic material of the profile seal in the area of at least one seal foot can have an increased Shore hardness compared to the rest of the material. Due to the increased shore hardness, it is possible to carry out mechanical transport of the endless sealing profile (e.g. via rollers) with precise positioning via the sealing foot having an increased shore hardness.
  • a first sealing foot preferably on the stop web side
  • a second sealing foot preferably on the side of the frame center seal opposite the stop web
  • the elastic material of the frame center seal in the area of the second seal foot can have a higher shore hardness than the rest of the material
  • the material in the area of at least one or the above-mentioned second sealing foot has a Shore hardness greater than 60 and the remaining material has a Shore hardness of less than 60.
  • the Shore hardness of the at least one or above-mentioned second sealing foot is preferably in the range from 70 to 80.
  • the profile seal can advantageously be designed as a coextrusion profile.
  • the profile seal is coextruded together with the materials of the at least one or above-mentioned second seal foot and the remaining profile of the profile seal.
  • non-foamed EPDM is provided as the material for the at least one or above-mentioned second sealing foot and foamed EPDM, in particular foam rubber, is provided for the material of the remaining profile areas of the profile seal.
  • the present invention relates, also claimed, a profile seal, in particular a frame center seal, made of elastic material for use in the rebate area between the outer and inner shell of a window frame accommodating a sash frame with a base body preferably equipped with hollow chambers, a stop web oriented upwards from the base body Stop surface for the sash frame, at least one sealing foot, the profile seal being provided as a peripheral, angular sealing frame with a butt joint at the end and in the respective corners of the sealing frame on the inside V-shaped notches and on the sealing frame on the outside straight-line incisions being provided opposite the notches.
  • This makes it possible to avoid vulcanized corner pieces as well as straight sealing pieces that have to be shaped or cut to length.
  • the invention ensures that an all-round sealing frame created from the frame center seal fits into the corner areas of the window frame with a right-angled inner course without forming any curvatures there.
  • the V-shaped notches are introduced transversely to the main extension direction of the frame center seal, that is to say in the installation direction of the seal.
  • the profile seal can preferably have a first seal foot, preferably on the stop web side, and a second seal foot, preferably located on the side of the profile seal opposite the stop web.
  • the hollow chambers of the frame center seal expediently run around the respective corner of the sealing frame or frame on the outside of the sealing frame in a non-cut state. This increases the stability of the frame center seal in the area of the V-shaped notches and the straight cuts on the outside.
  • V-shaped notches cover the hollow chambers of the base body of the frame center seal completely or almost completely. This in turn means that the sealing profile can be tilted by 90° and joined together particularly well in the respective corner area, since there are no partitions or partition wall components of the hollow chambers that have to be additionally deformed when folding in.
  • the respective notch and the incision form an uncut cross-sectional area, which delimits the hollow chambers on the underside and/or the second sealing foot and/or the first sealing foot on the upper side, there is a continuous, narrow, uncut area transverse to the longitudinal extension of the profile seal, which on the one hand comprises only very little material and can therefore act like a pivot axis, on the other hand effectively holds the sealing material together over the entire width of the profile seal.
  • stop web for stopping the casement or the insulator of the same does not have an integrally formed sealing lip.
  • the cut surfaces of the profile seal in the area of the V-shaped notch can be better connected to one another.
  • the stop surface of the stop web can preferably be flat. This achieves a larger contact surface and thus more effective sealing with respect to the casement or its insulator.
  • the stop surface of the stop web can also be oriented obliquely to a reference plane E running transversely to the mounting direction. This causes a particularly good seal.
  • the stop surface can also be designed to run parallel to the assembly direction.
  • the stop bar at least in its upper part, ie the area projecting beyond the base body of the frame center seal, can be oriented towards the side of the second seal foot. This also causes a particularly advantageous seal on the one hand and on the other hand a sufficient permanent dimensional stability of the frame center seal in use.
  • cut surfaces are expediently glued together in the area of the V-shaped notches, preferably in the area of the stop bar.
  • the joint surfaces or end faces of the profile seal formed by smooth cuts can be glued together, preferably in the area of the cut surface of the stop web and/or the second seal foot.
  • the frame center seal can also be separated from each other with a be constructed front-side bevel provided segments that abut each other over the entire surface in the area of the bevel.
  • This configuration has the advantage that, because of the segments, the frame center seal can only be processed manually, ie machining is not required.
  • the bevel preferably has an angle of 45° ⁇ 5°, preferably an angle of at least essentially 45°.
  • the present invention further relates to a facade construction, in particular in the form of a window or door construction, according to the preamble of claim 19, which is characterized in that the latter comprises a profile seal according to at least one of claims 1-18.
  • FIG. 1 shows an example of a section of a so-called blind frame 12 of a window construction, which is made up of outer frame profiles 12a and inner frame profiles 12b and insulating bars 15a, 15b located in between.
  • the frame profiles 12a, 12b can be made of metal, eg aluminum, or of plastic.
  • the insulating bars 15a, 15b connect the frame profiles 12a, 12b and ensure adequate thermal separation between the half-shells on the inside and outside of the window formed by the frame profiles 12a, 12b.
  • the frame 12 includes vertical portions (mullions) and horizontal portions (bars), creating window recesses that can be filled, for example, by a sash to fix the window (or door, not shown in the drawings).
  • the frame half-shells 12b can be stiffened relative to one another by means of stiffening brackets 11 .
  • the window frame contains 12 in 1 a frame center seal 1 disposed along the entire rectangular or square frame of the frame 12 running around.
  • the frame center seal 1 covers the area located between the outer frame half-shell 12a and the inner frame half-shell 12b. It therefore has a greater width than height.
  • the frame middle seal 1 serves to cover the area between the outer frame half-shell 12a and the inner frame half-shell 12b in a sealing manner and at the same time to form a sealing stop for the casement 13 .
  • the sash 13 comprises a wing shell 13a on the outside of the window and a wing shell 13b on the inside of the window.
  • insulating webs 16a, 16b are located between the two wing half shells 13a, 13b.
  • An insulating web 16b is formed as a pronounced chamber profile and serves to seal the rebate area 21 together with the frame center seal 1 towards the inside of the facade when the casement 13 is in the closed state.
  • the insulating web 16b presses against the frame center seal 1, for example in the area of the outer frame half-shell 12a or outer wing half-shell 13a.
  • a glazing element 17, for example a triple-glazed composite pane, can also be seen, which is held in the casement 13 by means of a holding profile 13c with the interposition of seals 18a, 18b.
  • the frame center seal 1 is fastened, for example, by means of a first seal foot 3 and a second seal foot 4 in groove-shaped recesses formed by the frame profile 12a, the insulating web 15a and the frame profile 12b.
  • the frame center seal 1 shown as an example extends over the entire gap formed by the two frame profiles 12a, 12b.
  • the gap on the inside of the window between the frame half-shell 12b of the window frame 12 and the sash half-shell 13b of the sash frame 13 is closed by a seal 24 fastened to the sash half-shell 13b when the casement 13 is in the closed state.
  • the frame center seal comprises a base body 2 in which, for example, at least one hollow chamber can be provided.
  • a total of three hollow chambers 7a, 7b and 7c are provided in the base body 2.
  • Ribs 9a to 9c are also arranged on the upper side of the base body 2.
  • a stop web 5 is provided above the base body 2 , which can extend in the direction of the second sealing foot 4 , for example.
  • Both the stop bar 5 and the base body 2 in the area of the stop bar are designed as a solid material, ie they do not have any hollow chambers.
  • the "base body 2 in the area of the stop bar 5" is the area of the base body 2 that is below the stop bar 5 and above the sealing foot 3 .
  • the stop web 5 comprises a preferably planar stop surface 10, which can also be oriented obliquely to the mounting direction M.
  • the oblique orientation of the stop surface 10 is in Figure 3a indicated by the dashed line E.
  • the stop surface can also be arranged parallel to the assembly direction. How out Figure 3a It can also be seen that there is no hollow chamber in the area of the stop bar 5 or in its underside area of the base body 2 .
  • a groove 6 is provided, into which a T-shaped web of the outer frame half-shell 12a engages.
  • Provided between the first sealing foot 3 and the second sealing foot 4 are two recesses which are separated from one another by a rib and into which corresponding T-shaped webs of the insulating web 15a engage.
  • the frame center seal 1 is preferably designed as a coextruded profile seal.
  • the coextruded profile seal comprises a material area with an increased shore hardness compared to a second material area with a lower shore hardness.
  • the area of the second seal foot 4 in particular has an increased shore hardness compared to the remaining area of the frame center seal 1 . In the area of increased shore hardness, this should be more than 60.
  • the Shore hardness of the second seal foot 4 is greater than 60, for example it is between 70 and 80. The reason for this is that this range is adapted for machine production of the frame center seal 1 . Due to the increased Shore hardness in this area, the frame center seal 1 can be transported and/or positioned exactly by means of rollers, which would not be possible with "normally soft" sealing material.
  • the material of the second sealing foot 4 is preferably unfoamed EPDM.
  • the remaining material of the profile seal is foamed EPDM. Foam rubber is particularly advantageous here.
  • the porosity of the "remaining area" of the profile seal in Figure 3a is indicated by the honeycomb cross-sectional structure, whereas the area of the second sealing foot 4 should not have such porosity.
  • the frame center seal 1 is designed as a peripheral frame, with the sealing profile on which the frame center seal 1 is based being processed in the corner areas as described in detail below and at the two front ends 25a, 25b, as in Figure 4c shown, is butt connected to each other.
  • the frame center seal 1 comprises a continuous one-piece sealing profile, machined in the corners, which is folded and butt-joined at one point.

  • V-shaped notches 14 are cut in the respective corner areas from the top onto the profile seal, i.e. in the mounting direction M (cf. Figure 3a ), incised.
  • the sealing profile is made in particular Figure 4b evident. This makes it possible to bend the profile seal by exactly 90° without causing a bulge.
  • FIG. 5a As can be seen, in the area of the V-shaped notch 14, on the one hand, a pronounced cut surface 23a, 23b is formed in the area of the stop web 5.
  • the hollow chambers 7a, 7b, 7c are uncovered, at least almost completely uncovered.
  • the rear incision 19 which extends over the first sealing foot 3, the bottom rib 9d and the second sealing foot 4, it becomes possible to fold the weatherseal through 90° without permanent curvature, as shown in FIG 7 is evident. Because the hollow chambers 7a, 7b, 7c are completely or almost completely exposed through the incision in the area of the V-shaped notch 14, only a very narrow cross-sectional area 20 remains, which Figure 3b is shown in black for clarity. This makes it possible to fold the sealing profile exactly by 90° without resulting in a curvature caused by the fold.
  • the cutting depth limits are each represented by the top level ST1 and the bottom level ST2.
