Abstract

A rubber elastic sealing profile (13) is provided round the casement (11) or fascia frame (12) and supports the magnetic means which are relatively movable to a restricted amount to hold the magnetizable parts or further magnetic means of the frame or casement sealingly against the sealing profile. The magnetic means or magnetizable parts can be fixed with the rubber elastic sealing profile on the overhang (17) of the frame or casement in a seal holding groove.

Description

The invention relates to a building closure, in particular door or window, the or whose openable Wing at least on the side and top of the frame with a Magnetic seal is sealed all around.

Well known building doors or windows sealed by rubber seals between the wing and the frame are arranged so that under the influence of closed wing can be compressed. The squeeze The rubber seals require a not insignificant one Pressure force that must be applied to the wing when this is closed. To securely seal the known To reach doors or windows, the contact pressure must be reached of the wing on the seal and thus on the frame be high enough. The contact pressure has the consequence that the Rubber seal stretched at least in important areas or is compressed. As a result of this expansion, the sealing material loses flexibility over time. The consequence of this aging process are leaks, possibly also mechanical destruction of the rubber seal, so that drafts can enter undesirably. Can worsen Conversely, the seals affect the wing to press. As a result, this can be relocated. Not exact settings of the position of the sash to the window frame can cause the seal to act unevenly is, so that in turn correspondingly uneven stresses the seal that the above described Aggravate signs of aging of the seal.

DE 40 11 351 is a magnetic door seal known, which has the features mentioned above. The Magnetic seal is a magnetic rod that is in a groove of a Door leaf is arranged and there by a sheet steel strip is held up. Is in the closed position of the door leaf a second magnetic bar opposite this magnetic bar. Both magnetic bars attract and the first magnetic bar seals the gap between the door leaf and the threshold from. This well-known magnetic door seal is true basically suitable for all-round sealing of a door, however, it is in need of considerable improvement. In particular, considerable adjustment paths of the first have an effect Magnetic rod disadvantageous, which are required when the gap to be sealed is large. There are in particular Difficulty in guiding the magnetic rod because of the risk of jamming especially when the magnetic rod is bent is considerable for long lengths. The magnetic rod must also be used large gap widths are designed to be very powerful, on the one hand the desired shift to the sealing position is guaranteed, but also the provision of the magnetic rod in its rest position when opening the wing. Any tolerances between the magnetic rod and its Management device act in the sense of leaks off, so that a reliable seal is questioned can be. If the magnetic rod is designed strongly, it causes So strong attraction forces are like that to open the wing required forces considerably and strain the wing fittings and the operator unnecessarily strong.

In contrast, the invention is based on the object a building door or window with the entrance to improve the features mentioned so that the required All around sealing with comparatively weak magnetic means can be achieved, with tolerances of the wing and the Frame with little influence on the closing behavior are and still a reliable seal can be achieved can.

This object is achieved in that on the wing or on Frame rubber-elastic sealing profile is present, the magnetic means carries limited mobility, the magnetizable Parts or other magnetic means of the frame or hold the wing sealing against the sealing profile.

It is important for the invention that the magnetic means limited flexibility by a rubber-elastic sealing profile are worn. This sealing profile can be used in conjunction achieve an excellent seal with the magnetic means, because the magnetic means magnetizable parts or are able to attract further magnetic means, so that the frame held on the sash or the sash on the frame is in contact with the sealing profile. The sealing profile is used to create a reliable seal between the sash and the frame. The rubber-elastic property of the sealing profile ensures making sure that smaller and larger tolerances are equally good can be compensated without the strength of the magnetic means must be interpreted differently or as a precaution strongly dimensioned magnetic means would have to be used. The relatively poorly dimensioned magnetic means cause the opening forces to open the closed Wing can be correspondingly low. To close the Wing only comparatively small forces are required, because the rubber elasticity of the sealing profile is chosen high can be. It is not necessary to use rubber elasticity or to train flexibility comparatively low, to create a permanently stable sealing profile, that permanently guarantees the existing elasticity of the rubber. Because the sealing effect of the sealing profile quasi decoupled and on the closing action of the magnetic means or of the magnetizable parts is shifted, the rubber elastic Sealing profiles only for durability be interpreted.

The completion of the building can be developed so that the magnetic means or the magnetizable parts on the frame and / or are arranged on the wing flap. This Design effects a seal where it is leading is necessary, namely outside of the building or inside of the building. Here is the usual door or window systems also the space required to be rubbery Sealing profiles or magnetic means and magnetizable To be able to arrange parts. For attaching the magnetic means or the magnetizable parts can also here can be easily taken care of. Possible misalignments of the wing in relation to the frame, this affects the seal only slightly because of the rubber-elastic sealing profile its intended elasticity across the frame level has, which is designed to bridge tolerances is.

It goes without saying here, as well as regarding the others Advantageous configurations of the Invention that instead of the aforementioned magnetizable Share also the other magnetic means mentioned above can be used.

It is preferable that the magnetic means or the magnetizable Parts with the rubber-elastic sealing profile on the frame and / or on the sash flap in a seal retaining groove are attached. This will make it anyway Attach seals in the sash flap or in the Frame overlap existing seal retaining groove also for Fastening of sealing profiles with magnetic means exploited. Since there are seal-holding grooves in both rollovers are available, the building closures can also with appropriate Double seals can be easily equipped.

But it is also possible to design the structure closure in such a way that the magnetic means or the magnetizable parts with the rubber-elastic sealing profile or with a holding profile in one between the frame and the sash flap existing groove on the rebate side of the wing or of the frame are attached. In a rebate side Groove of the wing or frame are rubber-elastic sealing profiles so arranged that there are closing or opening forces practically have no effect on the attachment of the profile. The opening forces act transversely to the locking forces and cannot overcome them. Beyond that such a design for narrow gaps between one Rollover and the associated counter profile are particularly suitable, because areas for fastening the sealing profile this point does not apply.

Result in further advantageous fastening options for the completion of the building in that the magnetic means or the magnetizable parts of one attached to the frame Closing bar or by one in a glazing bar holding groove a frame profile fixed bracket held are. The locking bar is not only used for reinforcement of the frame they carry, which is usually made of plastic exists and must be protected against attempts to break in, but it can also accommodate a comparatively voluminous Magnetic means or a magnetizable part serve, with space in the area between rollover and the Closing bar bearing profile is saved. The attachment the magnetic means or the magnetizable parts in one Glazing bead retaining groove ensures particularly high mechanical Anchoring stability at the same time easier Arrangement or fastening by means of a snap connection.

A further design of the building completion can be made in such a way that magnetic means or magnetizable Parts on the sash or frame also below or are arranged on a threshold. This gives a complete all-round sealing of the building closure with the magnetic means. A threshold can be without be further adapted to the magnetic seal, without constructive changes to the threshold in considerable scope would be necessary.

A significant increase in the range of elasticity the sealing profile can be achieved in that the rubber-elastic sealing profile with a bellows cross section is formed in which the magnetic means or magnetizable parts are protected. The bellows cross section the sealing profile allows considerable Movements in its main bellows direction, as well as across it. Accordingly, the magnetic means are also movable or relative movements between the sash and the frame or Tolerances between the latter can be easily mastered become. Protection of the magnetic means by the sealing profile has the consequence that the magnetic medium without consideration Environmental conditions in a conventional manner can.

Another advantageous embodiment of the building completion can be achieved if the rubber-elastic sealing profile has a hinged lip in which the magnetic means or encased the magnetizable parts as needed are arranged. With the hinged lip you can the magnetic means also considerable distances between the Bridge the sash and the frame, without one To worry about overloading the rubber-elastic sealing profile is.

An advantageous constructive embodiment results in that the rubber-elastic sealing profile with a Snap foot is attached to the sash or frame. With a Such a latching foot can be provided on the sash or on the frame Latching means without problems to fix the sealing profile be exploited.

This can be a further development of the building completion take place on the sash, on the frame or on a threshold in addition to a first rubber-elastic sealing profile a second rubber-elastic sealing profile is available is limited, the second magnetic means is relatively movable carries, the second magnetizable parts of the frame, the Wing or a threshold seal on the second sealing profile hold. This results in a double seal, which makes sense when particularly strict Sealing requirements should be met, e.g. with regard to very high fluctuations in air pressure. Double seals but are also advantageous when there are increased thermal insulation requirements or increased holding forces are required.

Relief of the rubber-elastic sealing profile of mechanical stresses can then in particular reach when the sash, the frame and / or the threshold to keep in a relative closed position are in which the rubber-elastic sealing profile a predetermined Takes sealing position. In this predetermined sealing position are the mechanical loads on the sealing profile due to the predetermination of this sealing position least. The means of achieving this relative Closed position of the sash and the frame or the threshold can be achieved by means of fittings. The The sash and / or the frame have stops, e.g. Striking plates which ensure the relative closing position. The closed position can be adjustable. In any case it is chosen so that the mechanical load on the rubber elastic Sealing profile is lowest when the wing closed is.

The building closure shown in Fig.1 is a door 10 with a frame 12 and with a door leaf 11, the Swiveling on the frame 12 via door frame straps 10 ' is attached. The frame 12 consists of an upper Frame spar, to which two vertical frame spars connect, which have a threshold 24 between them below. The Wing 11 has a door leaf that is inside in the usual way a casement can be arranged and attached.

Fig.2 shows the frame 12 and the wing 11 with in Section wing wing and frame cross sections shown. The spars are arranged essentially in one plane. However, there are frame flaps 16 and wing flaps 17 available, of which two each one Fold space 28 overlap that between the facing each other Faces of the spars.

The wing 11 and the frame 12 are made of rubber-elastic Sealing profiles 13 sealed against each other. Fig. 1 shows double seals. Both on the frame rollovers 16, as well as on the wing flaps 17, except for the area of threshold 24, double seals available. This is also shown in Fig. 2, for example.

Each of the seals shown in Fig.2 has except a sealing profile 13 magnetic means 14 and / or magnetizable Share 15. For the second sealing point are second magnetic means 14 'and / or second magnetizable parts 15 'available.

3 shows a greatly enlarged illustration, for example Formation of a sealing point between one Frame 12 and the wing flap 17, for example corresponding to the lower sealing points in Fig. 2. In the sealing area there is a sealing profile 13, the is formed with a bellows cross section 25 and one Has latching foot 27. With this locking foot 27 is the rubber elastic Seal profile 13 buttoned into a seal retaining groove 18 and locked with it. Within the sealing profile 13 magnetic means 14 are arranged. These are, for example a permanent magnetic material strip from one Plastic that is mixed with magnetic particles. Such Magnetic means are flexible and can accommodate elastic movements the rubber-elastic sealing profile 13 if necessary to adjust. The magnetic means 14 are on a wing side Profile surface 29 of the rubber-elastic sealing profile 13 attached, e.g. by gluing. Here could also be a magnetizable Sheet metal strips are present to the magnetic To form the field of the magnetic means 14.

There are magnetizable parts 15 on the wing 11, e.g. in the form of a along the entire edge length of the wing 11 continuous sheet metal strip. Instead, you can there may also be other magnetic means. Such magnetic means or the magnetizable parts 15 are from the magnetic means 14 tightened so that the sealing point sealed is when the wing 11 in the closed position shown is pivoted.

4 shows the rubber-elastic sealing profile 13 also attached to the flap 17, as in Fig.3. Also the profile design is corresponding. The is different Fixing the magnetizable parts 15 on the frame 12. A holder 23 is provided for the magnetizable parts 15, which is fixed with a foot piece 23 '. The foot piece 23 'engages in a glazing bead retaining groove 22 of the frame profile of the frame 12, which is normally used for this will latch a glass retaining bar with which a glazing a wing 11 is set. The bracket 23 holds the magnetizable parts 15 on one edge of the as a hollow profile trained frame 12 form-fitting against stress, which result from opening movements of the wing 11 and the magnetizable parts on the magnetic means 14 looking to keep.

5 are stiffened by stiffening profiles 30,31 Crossbars of a wing 11 and a frame 12 shown. The trained as a hollow section bars Posts are made with standard elements such as with a groove 20 adjacent to the rebate space 28 in the wing 11 or a glazing bead retaining groove 22 in the frame 12. The groove 20 on the rebate side is used for locking one rubber-elastic sealing profile 13 by means of its locking foot 27. A holder 23 for magnetizable parts 15 present in the form of a bar similar to the bracket 23 anchored in FIG. 4 with a foot in the glazing bead retaining groove 22 and on which a sheet metal strip is magnetized Part 15 is glued on. There is a middle seal between the rollovers 16.17.

According to Figure 6 are also a groove 20 of the wing 11th and a glazing bead retaining groove 22 of a frame 12 for attachment used by sealants. In the groove 20 is a holding profile 19 installed with an L-leg Holds magnetic means 14 in the area of the flap 17. in the Folding space 28 is a closing bar 21 which the Folding space-side end face of the frame 12 covers and attached to this. The attachment can be done with the help the glazing bead retaining groove 22 take place. With the locking bar 21 magnetic means 14 are firmly connected, transverse to Frame level also larger dimensions of the sealant can be accommodated and thus form a structural unit, that for narrow gaps between the rollover 17 and the neighboring one Frame 12 is particularly suitable. For this The reason was in Fig. 6 in the area of the wing flap 17 two interacting magnetic means 14 are shown schematically, each with a rubber-elastic sealing profile 13 can be formed. Fig. 6 also shows schematically another sealing point in the area of Frame rollover 16.

7, 8 show between the rollovers 16, 17 Seals on the rebate side with a rubber elastic Sealing profile 13, each with a hinged Lip 26 is provided.

According to FIG. 7, the sealing profile 13 has a foot 27 arranged in a spar of the wing 11, e.g. with a latch according to Fig. 5. The lip 26 runs essentially across the frame level, that is, in the plane of the rebate area encloses a magnetizable insert, namely magnetizable Parts e.g. in the form of magnetizable metal strips. When the wing 11 is closed, the elastic lip 26 lies on the frame side, in the area from here Magnetic means 14. As a result, the magnetizable Parts 15 pulled against the magnetic means 14. The folding room 28 is sealed against the passage of air.

In Figure 8 is a special frame profile with a vertical cross section of the groove 20 oriented to the frame plane shown, in which a foot 27 of a rubber-elastic sealing profile 13 is installed, e.g. through the illustrated Clamping. There is a V-shaped elastic lip 26 encased the magnetic means 14 with which the elastic Lip 26 adheres to magnetizable parts 15 which are on the wing 11 are attached. When the wing 11 is open, takes the elastic lip the position shown in dashed lines and thus covers the area of the groove 20 which consequently not dirty.

Both embodiments in Fig. 7,8 have in common that the opening of the door leaf, as in Fig. 5, for a stripping the magnetic means 14 from the magnetizable parts 15 or vice versa. The separation of the contiguous and to be separated from each other when opening the wing 11 Parts 14, 15 are not made transversely to these parts, but instead at least with a significant longitudinal component, which is the opening process relieved because lower opening forces are required are.

On the other hand, opening the wing is manageable, if opening movements occur in the substantially perpendicular to the main planes of the magnetic means 14 or the magnetizable parts 15. Usually done here a zipper-like opening, in which the Magnetic means 14 of the magnetizable parts 15 initially pulled apart perpendicular to each other only at a single point be, whereupon a split over the length the edges of the sash or frame. This is at least obviously for the area of the upper horizontal Spars and for the area of the lower horizontal Holms of a window or for the area of a threshold a door. Otherwise, opening can also have an impact that the wing 11 and the frame 12 are not exactly parallel are arranged to each other, but have slight warpage. These contribute to the opening forces initially primarily at a preferred location or at a preferred location Area and for a local separation of the magnetic means 14 lead from the magnetizable parts 15, after which the zipper-like opening described above takes place.

The schematic cross section shown in FIG the area of a threshold 24 shows a seal on the room side by means of two magnetic means 14, 14 ". The first magnetic means 14 "are in a rubber-elastic sealing profile 13 arranged, in the elastic lip 26, of which the means are enclosed. The profile 13 is with a Locking foot 27 locked in the wing flap 17. In the closed position of the wing 11 is the elastic profile against the threshold 24 drawn. Here is a locking bar on the inside 32 available, which with the threshold 24 e.g. by means of the illustrated rack 32 'is locked. The Turnover 17 facing magnet means 14 are present interact with the magnetic means 14 "of the elastic lip 26. This results in a particularly tight seal by the interaction of two magnetic means 14, 14 " Separate the magnetic means 14.14 "when opening the door leaf 11 is not critical, however, since the opening forces are initially in lead to separation at one point, namely on the door handle side, after which a zipper-like pull-off the elastic lip 26 is carried out by the locking bar 32.

In Fig. 10 there is only a schematic on the interior side Sealing shown, but in the area of the rollover 17 only with magnetizable parts 15, e.g. can be attached sheet metal strips. Magnetic means 14 are available on the threshold side where there are no space problems, so that such a design especially for small distances between threshold 24 and rollover 17 suitable is.

In addition, there is a second sealing point in FIG shown, again using a not shown rubber-elastic sealing profile 13. Am Door leaf 11 is a special drainer 33 on the outside available to accommodate second magnetic means 14 ' is trained. In the area of threshold 24 there are second ones Magnetizable means 15 'are present, which are from the magnetic means 14 'are pulled up when the wing 11 the has assumed the position shown. If the wing is opened, so the magnetizable parts 15 'fall into one for they provided the receiving space 34 of the threshold 24 back and interfere there when the threshold 24 is exceeded Not. So that the magnetizable parts 15 in this area the threshold 24 have the required vertical guidance, they are on a lightweight material Guide bar 35 arranged which is the vertical guide the parts 15 'guaranteed in both directions of the double arrow.

From the detailed descriptions of the rubber elastic Sealing profiles 13 can be seen that these when opening and closing the wing 11 are mechanically stressed. The stress for the rest, namely with the wing closed 11, can advantageously be done so that none or only slight expansions of the rubber-elastic material take place. As a result, the material does not tire if you assume that occur when pivoting the wing 11 Opening strains of the material can be permanently controlled are. Those carried out with the means described above Building closures are therefore advantageously designed that the wing 11, the frame 12 and / or the threshold 24 the rubber-elastic sealing profile 13 or 13 'do not strain or only slightly. In this predetermined The components of the building lock can be sealed be held by mechanical means. Fig.2 only shows for example a trap 37, which e.g. of a Strike plate of the frame engages latch opening 36 formed. In this position, a relative arrangement of the Wing 11, the frame 12 and the threshold 24 to each other this ensures that the rubber-elastic sealing profiles 13 the sealing position predetermined for them take, so without stressing the rubber elastic Material.
