Description

TECHNICAL AREA

The present invention relates to a lowering seal for a thresholdless door for sealing a gap between a door leaf and a floor.

STATE OF THE ART

Automatically mechanically lowerable sealing devices are known. They are generally used for threshold-free doors to seal the lower gap between the door leaf and floor against draft, sound and light transmission. Proven has a seal, as for example in EP 0 338 974 is disclosed. The actuation of the sealing device takes place automatically when closing and opening the door. Examples of corresponding lowering mechanisms are in EP 0 509 961 . DE 19 516 530 . DE 3 526 720 . DE 3 418 438 and DE 3 427 938 disclosed. The actuation of the lowering seal is carried out on one or two sides, but usually frontally by a door leaf protruding spring-loaded release pin is pressed when closing the door. Other types of triggering mechanisms are also known.

Furthermore, it is off EP 1 191 182 such as EP 1 308 590 known to provide such seals with a through hole, which serves to receive a locking bolt or - rod. The rod passes through a housing rail and a sealing strip of Absenkdichtung. As a result, even with the use of such a locking bar, the entire width of the door can be sealed, wherein the bolt can be actuated independently of the lowering mechanism of the sealing strip.

EP 2 050 918 discloses a lowering seal having such a passage opening, which has shortenable portions which are not penetrated by the lowering mechanism.

IT 1392997 VI describes a lowering seal with a separate end piece with a passage opening and a sealing lip, wherein the tail must be lowered manually.

DE 20 2014 100 774 U shows a rod guide plate, which is screwed to the lower end face of the door, so that the passage opening of the housing rail does not have to serve as a guide for the locking rod.

In the known devices, however, limits the width of the housing rail, the diameter of the locking bar and the locking bolt. That the rod or bolt must either have a rectangular cross-section for narrow seals to be sufficiently stable, or the seal must be used with a weakened rod of reduced cross-section.

PRESENTATION OF THE INVENTION

It is therefore an object of the invention to provide a lowering seal which can also be used with relatively thick locking bars.

This object is achieved by a lowering seal having the features of patent claim 1.

The inventive lowering seal for a threshold-free door for sealing a gap between a door leaf and a floor has a housing rail, a support rail, a sealing profile and a lowering mechanism, wherein the sealing profile arranged on the support rail, in particular held. The support rail can be raised and lowered together with the sealing profile by means of the lowering mechanism relative to the housing rail. The lowering seal has a passage opening which extends transversely to the longitudinal direction of the lowering seal and parallel to the lowering and raising direction of the support rail and which of a Locking bar is enforceable. The support rail has a base rail and an extension means adjoining the base rail in the longitudinal direction of the lowering seal, wherein the passage opening extends along the extension means and / or through the expansion means and has a clear width over the entire height of the extension means, which is greater than the clear width the base rail or which alternatively or additionally corresponds at least to the outer width of the base rail. The clear widths and the outer width extend perpendicular to the longitudinal direction and perpendicular to the lowering and raising direction. According to the invention, the base rail, the expansion means and the sealing profile can be raised and lowered together by means of the lowering mechanism.

In this text the term "locking bar" or "bar" is used. It also includes locking bolts or other elongated structures, which are suitable to enforce the lowering seal and make a locking towards the ground, for example by engaging in a bottom recess. In particular, the rod may be part of a drive bolt which is connected to the door handle, or a channel latch which is operated separately.

The lowering seal according to the invention makes it possible to use wider rods than the state of the art, thanks to the broader passage opening and preferably thanks to the widened enlarging means. It can be used, for example, with constant cross-section of Absenkdichtung rods, which have a 1 to 2 mm larger diameter than the previously used rods.

In a first embodiment, only the clear width of the expansion means is wider than the inner dimension of the housing rail. In other embodiments, the outer dimension is wider and at least partially fills the game, which has the support rail normally in the housing rail.

An advantage of the inventive solution is that the extension can take place within the housing rail. That is, the lowering seal or the housing rail may have the same cross-section as the known seals. The housing rail extends integrally over the entire length, thereby protecting the internal parts.

It is also advantageous that the rod does not have to be guided through the base rail of the support rail, so that it can be designed arbitrarily. If the inside of the expansion means is formed flat, the expansion means slides along the rod virtually without resistance and vice versa, and the relative movement of the rod and the carrier rail relative to one another is not hindered. A special guide like in DE 20 2014 100 774 U is unnecessary.

Preferably, the sealing profile extends over the entire length of the base rail and the expansion means.

Preferably, the expansion means is arranged on the base rail and fixed relative to this, in particular held. As a result, the composition of the seal is facilitated and ensures the joint movement during lowering and lifting. Furthermore, the carrier rail already known from the above-mentioned prior art can be used as a base rail; i.e. it can have this profile shape.

The sealing profile is usually made of an elastomeric material. It is preferably integrally formed or attached to the base rail. As a result, the sealing profile is connected to the carrier rail virtually over the entire length of the seal. It preferably extends at least over the entire length of the housing rail. Depending on the embodiment, it is even on one or both sides of the housing rail in the longitudinal direction.

Preferably, however, the sealing profile is not attached directly to the expansion means, but runs loose in this area. As a result, the side walls of the expansion means can be made very thin.

Preferably, the sealing profile has two upwardly directed legs, which rest in a sliding and sealing manner against the inner walls of the housing rail. Preferably The legs extend over the entire length of the sealing profile, ie also along the expansion means.

Preferably, the sealing profile is integrally formed or it consists of several firmly interconnected parts. These parts are, for example, glued together or welded together.

Preferably, the expansion means does not form the end of the lowering seal, but there is another end piece, which adjoins the extension means at the end of the expansion means facing away from the base rail. The sealing profile preferably extends over the entire length of the end piece. The end piece can be raised and lowered together with the base rail, the expansion means and the sealing profile by means of the lowering mechanism. Thus, the expansion means forms an interruption in the carrier rail. Tail and base rail are preferably formed the same and the sealing profile is preferably integrally formed or held both on the base rail as well as on the tail. Preferably, the sealing profile extends without interruption over the entire base rail, the expansion means and the tail.

Preferably, the expansion means is arranged on the end piece and fixed relative to this, in particular held. As a result, the expansion means can be attached at one end to the base rail and at the other end to the tail. It thus forms a bridge between the base rail and tail.

Preferably, the base rail and the end piece are formed identically in their cross section. The tail is thus preferably made of the known from the prior art profiles of the support rail.

The base rail, end piece and extension means preferably together form the carrier rail, which preferably does not protrude on both sides of the housing rail, but preferably has the same length or is slightly shorter.

So that the rod does not hinder the lowering, extends the mechanical Lowering mechanism preferably only along the base rail and ends preferably spaced from the expansion means.

The expansion means may be of any desired design, as long as it allows a passage opening with a larger clear width than would allow the rest of the carrier rail. In a preferred embodiment, the expansion means comprises two plates. These are preferably bent outwards. Preferably, at least one of the plates, preferably both plates are narrow compared to the wall thickness of the base rail

The panels are preferably secured to opposite, in use, vertically extending side walls of the base rail and, if present, the end piece. The attachment to the base rail and the tail is preferably carried out by means of a rivet pin or bolt, which is driven by the two opposite side walls of the base rail and the tail and thereby fixes the inside of the side walls adjacent side wings.

At least one of the two plates, preferably both plates, have a wall thickness which is smaller than the corresponding wall thicknesses of the base rail.

In a preferred embodiment, the expansion means consists of these two plates.

Preferably, each plate has a base plate, which merges at opposite ends in each case a side wing, wherein on one of the two side wings an angled wing is arranged. Preferably, the base plate is bent outwards. The bending of the base plate can be continuous, so arcuate. However, it can also be done in one or more stages. The side wings are preferably flat.

Preferably, one end face of the base rail forms a lower end stop for the base plates, the base plates projecting the side wings down. As a result, the plates can not be longitudinally relative to the base rail move. Preferably, the tail also forms such a stop, so that a displacement relative to the end piece is impossible. These stops form a rotation of the rivet.

Preferably, the angled wing in the lower region has a shape which forms a counterpart to a region of the inside of the base rail and, if present, the end piece, so that the connection between the angled blade and this region forms a further anti-rotation.

Preferably, the two plates are identical. They are in one embodiment, two separate parts, which are arranged mirrored to each other, so that the one angled wings in the tail and the other angled wings is arranged in the base rail.

In another embodiment, the two plates are formed integrally together, each having a base plate and two side wings, wherein the common angled wing forms the connecting piece between the two plates. At the open end of the extender, i. at the end opposite the angled wing or tie bar, a spacer, e.g. clamp a spacer sleeve into the side walls of the carrier rail.

Further embodiments are given in the dependent claims.

DESCRIPTION OF PREFERRED EMBODIMENTS

FIG. 1 shows a lowering seal according to the invention, which is traversed by a rod 4 or a bolt of a Kant- or driving bar. The rod 4 is movable relative to the lowering seal in direction A. That is, the rod 4 and the Absenkdichtung can be raised and lowered independently.

The lowering seal has a housing rail 1, in which a sealing strip in the direction A is held raised and lowered. The sealing strip comprises a carrier rail 2 and an elastomeric sealing profile 3 fastened thereto. The housing rail 1 and carrier rail 2 are preferably made of metal, in particular of aluminum. In the downwardly open, substantially U-shaped housing rail 1, a non-visible mechanical lowering mechanism of known type is arranged, which ends at the end face of the Absenkdichtung not shown in an operating knob of known type, which protrudes the housing rail 1 and which upon closing of the Door leaf is pressed and thus actuates the lowering mechanism. It is also possible to use other types of mechanical lowering mechanisms and triggering elements.

In the raised state according to FIG. 1 the sealing strip 2, 3 is received between the side walls 11 of the housing rail 1. In the upper web, a passage opening 12 in the housing rail 1 is present in an end-side end region. The passage opening 12 is preferably circular. But she can also do another Have shape. It may in particular be oval or rectangular. This passage opening 12 is penetrated by the rod 4. As in the FIGS. 3 to 6 can be seen, the sealing profile 3 has a corresponding passage opening 30. The passage opening 12 in the housing rail 1 is preferably dimensioned such that it guides the rod 4; ie it is insignificantly larger than the diameter of the rod 4. The passage opening 30 in the sealing profile 3 is preferably formed as a slot, wherein the slot in the transverse direction is insignificantly larger than the rod diameter. As a result, the tightness is guaranteed.

By contrast, the support rail 2 does not simply have a passage opening in the region of the rod 4. The support rail 2 is formed in this area rather than extension means 5.

As in FIG. 2 is clearly visible, the support rail 2 has a base rail 20, which is formed from an upwardly open, substantially U-shaped rail of known type. It has a lower region which serves for fastening the sealing profile 3. This base rail 20 extends over approximately the entire length of the housing rail 1 into the vicinity of the passage opening 12. The base rail 20 is connected to the mechanical lowering mechanism and via this with the housing rail 1. The lowering mechanism extends, except for any triggering elements, preferably only in the base rail 20 and ends at a distance from the expansion means 5.

The expansion means 5 adjoins the base rail 20. In this example, it is fastened to the inner walls of the base rail 20 with a first fastening element 23, here with a first rivet pin.

At the opposite end of the expansion means 5, an end piece 21 connects. This is identical in shape to the base rail 20, but much shorter. Like the base rail, it also preferably consists of metal, in particular aluminum. The expansion means 5 is also fixed to the inner walls of this end piece 21 by means of a second fastening element 24, here by means of a second Nietstifts.

As in the FIGS. 7 and 8 can be clearly seen, the expansion means 5, a through hole 25 with a larger clear width B _E as the adjacent base rail 20 and as the adjacent end piece 21. The clear width of the base rail 20 is in FIG. 8 indicated with B _B. It can thus be used with a diameter of a rod 4, which is larger than it would allow the rest of the carrier rail 2.

The sealing profile 3 is fastened to the base rail 20 and to the end piece 21, but not to the expansion means 5. However, it extends over the entire length L of the seal, that is also along the region of the enlarging means 5.

Thanks to the rigid and rigid connection of base rail 20, extension means 21 and end piece 22, these three parts can be lowered and raised together with the sealing profile by means of the same lowering mechanism, although the mechanism is only connected to the base rail 20, but not to the other elements of the sealing strip ,

In the FIGS. 9 to 12 is recognizable as the expansion means 5 in the first embodiment according to the FIGS. 1 to 8 is trained. The expansion means 5 consists of two plates 22, one of which in the FIGS. 9 to 12 is shown. The other plate 22 is preferably formed identically, but arranged rotated by 180 ° in the seal.

At least one of the plates 22, preferably both plates 22 are formed very narrow or thin. They are in particular substantially thinner than the side walls of the base rail 20. They are preferably made of a metal or plastic. Preferably, they are made of steel. They are preferably rigid, not resilient.

The plate 22 has a base body 220, which is bent outwards. Here the bend is continuous. On both sides of the main body 220 close to side wings 221, 222, which are each provided with a mounting opening 224, 225. These are enforced by the respective rivet pin 23, 24. Adjacent to one of the side wings 222 is an angled wing 223. The angle is preferably 90 °. This Angled wings 223 serves as a spacer when the plate 22 between the base rail 20 and end piece 21 is inserted. The length of the wing 223 preferably corresponds to the clear width of the female part, ie the base rail 20 or the end piece 21.

The angled wing 223 has a taper 226 in the lower region, which corresponds to the inner profile of the end piece 21 or the base rail 20. As a result, the angled wing 223 fits positively into this cavity and thus forms an anti-rotation.

A further anti-rotation is ensured by the fact that the base body 220 has an edge 227 projecting in relation to the side wings 221, 222. This edge 227 abuts against the lower end side of the base rail 20 and the end piece 21. It also serves to maintain the distance between the end piece 21 and the base rail.

As in FIG. 8 it can be seen, the opposing second plate 22 'of the expansion means is arranged so that its angled wing 223' is disposed in the base rail 20, wherein the angled wing 223 of the first plate 20 is located in the end piece 21.

The inner and outer walls of the base body 220, 220 'are preferably smooth. As a result, the expansion means 5 can be moved approximately friction-free relative to the rod 4.

In the FIGS. 13 to 15 a second embodiment of a plate 22 of the expansion means 5 is shown. Again, two identically formed, but mirror-symmetrically arranged plates 22 form the expansion means 5. The plate 22 is formed virtually identical to the already described plate. However, the base plate 220 is stepped and not bent outward continuously.

In the embodiment according to the FIGS. 16 to 18 the expansion means 5 is not formed by two separate plates, but by an integral part consisting essentially of the two plates. An angled wing 223 forms a Connecting web between two side wings 222, 222 '. On the opposite side no angled wings is present, but the local side wings 221, 221 'ends free. Depending on the embodiment, a spacer, such as a spacer sleeve is clamped in this free end.

The lowering seal according to the invention with the subdivided carrier rail can thus be used with relatively thick and therefore stable propellor or can-bolt bars.
