Definitions
- the present invention relates to a seal for a sillless door.
- Door seals for sealing a lower end face of a threshold-free door are known. They should prevent light transmission and also offer soundproofing. Depending on the embodiment, an air passage should also be avoided.
- EP 0 338 974 discloses a lowerable door seal with a U-shaped housing rail and a sealing strip with a support profile and a U-shaped elastomeric sealing profile.
- the sealing strip can be automatically raised and lowered in the housing rail, the movement taking place relative to the housing rail.
- the sealing profile has two legs and a curved sealing web connecting these two legs, which rests sealingly on the floor in the lowered state of the sealing strip.
- the sealing profile is attached to the carrier rail on both sides. This seal has proven itself in practice.
- EP 2 554 774 discloses a similar seal, the fastening of the sealing profile on both sides on the support rail being carried out at different heights.
- EP 0 841 457 describes a V-shaped sealing profile of a lowerable door seal, which has two downwardly directed feet and inwardly directed abutments into a cavity on which the carrier profile rests.
- EP 1 233 137 proposes various means for improving the sound insulation, some of which are arranged on the insides of the legs and protrude into a cavity formed by the two legs and the sealing web of the sealing profile.
- the seal according to the invention for a threshold-free door for sealing a gap between a door leaf and a floor has a support rail and a sealing profile held on the support rail.
- the sealing profile has an essentially U-shaped cross section with two legs and a sealing web connecting the two legs to one another for sealing support on the floor.
- at least two strips have a thickness which is greater than the thickness of the adjacent region of the leg.
- the thickness of the strip is to be understood here as the extension parallel to the transverse central axis. The thickness is thus the height of the strip.
- the length of the strip is the dimension transverse to the transverse central axis and transverse to the longitudinal central axis of the seal.
- the Thickness of the leg is the wall thickness of the leg and is thus the extent which runs at an angle to the transverse central axis and transversely to the longitudinal central axis of the seal.
- These thicker strips are located on each of the legs. They are preferably located approximately at the same height as the legs. These strips are preferably approximately twice as thick or more than twice as thick as the adjacent region of the leg to which they are attached. The two legs are preferably of the same thickness.
- the at least one strip preferably extends over the entire length of the sealing profile, wherein it preferably has no interruptions. It preferably has the same cross section over the entire length of the sealing profile.
- this shape shows very good sound insulation values on the test stand, which differ significantly from the seals used up to now. This is particularly the case when the seal is an automatic lowering seal with a known spring-loaded lowering mechanism.
- Typical measured sound insulation values are 54 to 56 dB compared to 46 to 50 dB of the known seals. Doors with simple seals usually have sound insulation values of around 27 dB.
- the sound insulation values of brick walls are typically around 55 dB. The higher the measured value, the better the sound insulation.
- At least one of the strips preferably runs at a distance from the underside of the carrier rail. All strips preferably run at a distance from this underside. This refers to the raised or unloaded condition of the seal. If the seal is lowered or if it rests on the floor in a sealing manner, the sealing profile is usually out of symmetry in the lateral direction with respect to the support rail shifted along the longitudinal central axis. In this displaced state, one strip can usually rest on the underside of the carrier rail, the distance between the other strip and the underside having been increased.

- each leg Preferably, exactly one strip is arranged on each leg.
- the strip can be arranged in a connection area of the sealing web. In a preferred embodiment, however, it is located at a distance from the connection area of the sealing web.
- strips which are arranged on different legs are arranged mirror-symmetrically to one another along a transverse central axis of the seal, wherein they are formed mirror-symmetrically to one another along this transverse central axis.
- the entire sealing profile or the entire sealing strip including the carrier profile or the entire seal is preferably designed mirror-symmetrically to the transverse central axis.
- the sealing profile can also be designed offset in height, as shown in FIG EP 2 554 774 the case is. The offset can only relate to the fastening of the sealing profile to the support rail and / or it can relate to the arrangement of the strips. The offset arrangement of individual parts enables an optimally narrow design of the seal.
- At least one of the strips ends at a distance from the transverse central axis of the seal.
- all of the strips on the legs end at a distance from one another.
- the sealing web is made thinner than a to the strips of adjacent areas of the legs.
- Optimized sound insulation values are achieved if the at least one strip extends at an angle of 80 ° - 100 ° to the transverse center axis of the seal.
- a further optimization of the sound insulation values is achieved in that at least one of the
- the strip has a substantially rectangular cross-section, one side of the rectangle being bent in the shape of a part of a circle and this side forming a free end of the strip protruding into the cavity.
- At least one of the strips can be hollow or solid. Massive is to be understood here in the sense of "filled in”.
- the sealing web is preferably free of projections or ribs on its outside, which are directed downwards towards the floor.
- the sealing web is preferably designed to be curved in order to again optimize the deformation, to increase the contact surface and thus to optimize the soundproofing.

- the space dividing element is an angled web with two ends and with two angles, both ends being arranged on the sealing web at a distance from one another. These room dividing elements also improve the sound insulation. Depending on the embodiment, they contact the strips when the seal is lowered or sealingly resting on the floor, or they contact one another. In other exemplary embodiments, in this state too, they run at a distance from one another and / or at a distance from the strips.
- the elastomer sealing profile is preferably formed in one piece. In its basic form, it preferably corresponds to the tried and tested profile EP 0 338 974 . It preferably has an essentially U-shaped cross section, with the two legs, preferably of equal length, and the sealing web connecting the two legs.
- the sealing web is preferably designed to be curved.
- the two legs are directed upwards and preferably each have a free end. The legs, preferably their free ends, slide against the inside of the housing rail.

Adjacent to the upper web 11, there is an inwardly protruding projection 12 on the inside of both side walls 10, which extends parallel to the upper web 10, preferably over the entire length of the housing rail 1. In the groove 13 formed between the upper web 10 and the projections 12, a slide or force transmission rod (not shown) is held, which transmits an external triggering force acting on an actuating rod to leaf springs of the lowering mechanism.
- These items are, for example, off EP 0 509 961 and DE 19 516 530 well known and not shown here.
- the carrier rail 2 has a fastening body 21 with two laterally arranged receiving grooves 22.
- the receiving grooves 22 are designed to be open to the side and are undercut. They or at least their receiving openings preferably incline slightly downwards towards the open end of the housing rail 1. In other words, the receiving openings are inclined towards a transverse central axis Q of the seal, this angle being relatively small.
- the fastening body 21 has an underside 23 which is preferably flat. In other words, it has no projections or depressions.
- the bottom 23 is preferably designed to be slightly inclined towards the transverse central axis Q of the seal, whereby it inclines downwards towards the outside.
- two side walls 20 extend upward from the fastening body 21.
- the two side walls 20 form an upwardly open U-shaped groove in which the lowering mechanism can extend.
- the sealing profile 3 is U-shaped. It has two legs 30 and a sealing web 32 connecting these legs 30.
- the two legs 30 are designed to end freely at the top. When the seal is lowered, they slide against the insides of the side walls 10 of the housing rail 1 and seal laterally in the lowered state, as shown in FIG Figure 2 is easily recognizable.
- the legs 30 are preferably not connected to the support rail 2 at their free end.

- a lateral spreading rib 38 is integrally formed on the inside of the leg, here in the area of the bend.
- the sealing web 32 is curved. It is thinner than the adjoining area of the legs 30.
- the transition between the leg 30 and the sealing web 32 is formed in this example by a step 33. Is how in Figure 8 If there is no step, the transition between the leg and the sealing web is to be found where, at least in the sealing state of the seal resting on the floor, the essentially horizontal area of the sealing profile in the essentially vertical or vertical portion of the sealing profile transforms. This definition applies to all exemplary embodiments in which the sealing web has a thickness which is essentially the same as the thickness of the adjacent region of the legs.
- the transition in the variant according to Figure 9 is formed by a notch or taper 39 of the sealing profile 3 between the leg 30 and the sealing web 32.
- the legs 30 have the same thickness over their entire length.
- the sealing web 32 is also of the same thickness over its entire length.
- a fastening rib 31 is formed on the inside of each leg 30.
- it has a structure similar to that of a fir tree.
- This fastening rib 31 engages in the undercut receiving groove 22 facing it, as a result of which the sealing profile 3 is fastened to the carrier profile 2 on both sides.
- the carrier profile 2 and the sealing profile 3 can thus be lowered and raised together relative to the housing rail 1.
- At least one of the two legs 30 has at least one strip 34 below the fastening ribs 31 and at a distance from them.
- a strip 34 is formed on each leg 30. It is preferably formed in one piece with the rest of the sealing profile. It is preferably made of the same material as the rest of the sealing profile. Both strips 34 are preferably at the same height and are thus opposite one another.
- the entire sealing profile 3 is preferably made of the same material and does not have any zones of different density.
- at least the area of the sealing profile 3 adjacent to the strip 34 is made from the same material and with the same density.
- the strip can also be glued or welded on. However, the one-piece and unitary embodiment of the sealing profile is clearly preferred.
- the strips 34 are located below the underside 23 of the support rail 2, but at a distance from it. This applies to the unloaded state, when the sealing bend does not lie tightly on the floor. If it rests in a sealing manner, one of the strips 34 touches the support rail and the other strip is further spaced from the support rail than before. This takes place due to the grinding movement of the sealing profile when the support rail is lowered while the door is being closed.
- the strip 34 is also at a distance from the step 33, which leads to the sealing web 32.
- the strips 34 are preferably significantly thicker than the area of the legs 30 adjacent to them and preferably significantly thicker than the sealing web 32. Preferably, the strips 34 are at least twice as thick or many times thicker than the sealing web 32.
- the thickness of the strips 34 (in Figure 2 the height) is preferably 3 to 5 mm, with a typical thickness of the sealing web 32 of 0.5 to 1.5 mm.
- the length of the strips 34 (in Figure 2 the horizontal extent in the plane of the drawing sheet is preferably 4 to 6 mm.
- the strips 34 preferably extend into the cavity 37 in a direction perpendicular to the longitudinal direction of the legs 30. They preferably do not extend as far as the transverse central axis Q of the seal, but rather end beforehand. As a result, the two opposite strips 34 do not touch.
- the two opposite strips 34 are preferably designed identically, as shown here, and are arranged mirror-symmetrically to one another. They are massive, i.e. filled in, trained.
- Each strip 34 has a substantially rectangular cross section with a free rounded end 341.
- FIGS 8 and 9 are variants of the sealing profile according to Figure 1 shown.
- the fastening ribs 31 are shown in dashed lines. This is to show that these and the other variants can have a different shape.
- the housing rail 1 is shaped differently in order to enable a different type of fastening of the lowering mechanism and a reduction in the overall height of the seal.
- the sealing profile 3 is designed similarly to the first exemplary embodiment, with the limbs 30 in the region of the strips 34 being made thicker than at the free end of the limbs.
- the free end of the legs has a similar thickness to the sealing web 32.
- the strips 34 are arranged in the transition regions between the legs 30 and the sealing web 32. There is no separate step 33.
- the two strips 34 are of the same length as in the first example according to FIG Figures 1 and 2 . Since the seal is made wider, however, they do not protrude almost to the middle of the cavity 37 or almost to the transverse central axis Q, as in the first example. In this example, they end approximately halfway to the transverse central axis Q or earlier.
- the strips 34 are hollow.
- the corresponding cavity 340 is preferably filled with air.
- a space dividing element in the form of a rib 36 which is formed centrally on the inside of the sealing web 32 and protrudes upward into the cavity 37.
- This rib 36 preferably ends at a distance from the strips 34.
- This rib 36 preferably touches the strips 34 when it is lowered and resting on the floor. This allows individual at least approximately closed chambers to be formed in the cavity. This increases the sound insulation.
- the rib 36 is preferably straight and it is preferably at least as thick as the sealing web 32. Its thickness preferably corresponds approximately to the thickness of the legs 30.
- the rib 36 is preferably made so thick that it can protrude upward on its own.
- the rib 36 can be formed in one piece with the rest of the sealing profile and preferably consist of the same material without stiffening means. However, it can also be made of a different material or stiffened and / or glued, welded or otherwise connected to the sealing web 32.
- ribs 36 which are arranged at a distance from one another on the sealing web 32.
- they are designed to be the same length. However, they can also be of different lengths.
- none of the three ribs makes contact with the strips 34. In this example, however, they protrude into the intermediate area defined by the two strips 34.
- two, four or more ribs 36 are present.
- a web 35 is arranged on the sealing web 32, with both ends being fastened or molded onto the sealing web 23.
- the web 35 preferably has three legs which are at an angle to one another. Together with the sealing web 32, they form a trapezoid with a rounded side.
- the web 35 also preferably does not contact the strips 34.
- Figure 7 shows a variant with a narrow seal, relatively short strips 34, which only extend approximately half the way to the transverse central axis Q, and with a web 35.
- sealing profiles according to Figures 1 to 7 can also be combined with each other to create new variants.
- sealing webs 32 with and without space dividing elements can be combined with hollow strips 34 or the shape of the legs 30 and / or the fastening ribs 31 can be changed.
- the seal according to the invention has surprisingly good sound insulation.

Description
Die vorliegende Erfindung betrifft eine Dichtung für eine schwellenlose Tür.The present invention relates to a seal for a sillless door.
Türdichtungen zum Abdichten einer unteren Stirnfläche einer schwellenlosen Tür sind bekannt. Sie sollen einen Lichtdurchlass verhindern und auch einen Schallschutz bieten. Je nach Ausführungsform soll auch ein Luftdurchlass vermieden werden.Door seals for sealing a lower end face of a threshold-free door are known. They should prevent light transmission and also offer soundproofing. Depending on the embodiment, an air passage should also be avoided.
Im Stand der Technik werden verschiedene Lösungen vorgeschlagen, welche den Schallschutz optimieren sollen. So zeigt
Es ist deshalb eine Aufgabe der Erfindung, eine Dichtung für eine schwellenlose Tür zu schaffen, welche einen verbesserten Schallschutz aufweist.It is therefore an object of the invention to create a seal for a threshold-free door which has improved sound insulation.
Diese Aufgabe löst eine Dichtung mit den Merkmalen des Anspruchs 1.This object is achieved by a seal with the features of
Die erfindungsgemässe Dichtung für eine schwellenlose Tür zur Dichtung eines Spalts zwischen einem Türflügel und einem Boden weist eine Trägerschiene und ein an der Trägerschiene gehaltenes Dichtungsprofil auf. Das Dichtungsprofil weist einen im Wesentlichen u-förmigen Querschnitt auf mit zwei Schenkeln und einem die zwei Schenkel miteinander verbindenden Dichtungssteg zur dichtenden Auflage auf dem Boden. Es ist ein Hohlraum vorhanden, welcher durch eine Unterseite der Trägerschiene, den Schenkeln und dem Dichtungssteg definiert ist, wobei das Dichtungsprofil an jedem Schenkel mindestens einen an einer Innenseite des Schenkels angeordneten und in den Hohlraum hineinragenden Streifen aufweist zur Verbesserung des Schallschutzes. Erfindungsgemäss weisen mindestens zwei Streifen eine Dicke auf, welche grösser ist als die Dicke des benachbarten Bereichs des Schenkels.The seal according to the invention for a threshold-free door for sealing a gap between a door leaf and a floor has a support rail and a sealing profile held on the support rail. The sealing profile has an essentially U-shaped cross section with two legs and a sealing web connecting the two legs to one another for sealing support on the floor. There is a cavity which is defined by an underside of the support rail, the legs and the sealing web, the sealing profile on each leg having at least one strip arranged on an inner side of the leg and protruding into the cavity to improve the sound insulation. According to the invention, at least two strips have a thickness which is greater than the thickness of the adjacent region of the leg.
Die Dicke des Streifens ist hier als die Ausdehnung parallel zur Quermittelachse zu verstehen. Die Dicke ist somit die Höhe des Streifens. Die Länge des Streifens ist die Ausdehnung quer zur Quermittelachse und quer zur Längsmittelachse der Dichtung. Die Dicke des Schenkels ist die Wanddicke des Schenkels und ist somit die Ausdehnung, welche in einem Winkel zur Quermittelachse und quer zur Längsmittelachse der Dichtung verläuft.The thickness of the strip is to be understood here as the extension parallel to the transverse central axis. The thickness is thus the height of the strip. The length of the strip is the dimension transverse to the transverse central axis and transverse to the longitudinal central axis of the seal. The Thickness of the leg is the wall thickness of the leg and is thus the extent which runs at an angle to the transverse central axis and transversely to the longitudinal central axis of the seal.
Diese dicker ausgebildeten Streifen befinden sich an je einem der Schenkel. Vorzugsweise befinden sie sich annähernd auf gleicher Höhe der Schenkel. Vorzugsweise sind diese Streifen annähernd doppelt so dick oder mehr als doppelt so dick wie der benachbarte Bereich des Schenkels, an welchem sie angebracht sind. Vorzugsweise sind die zwei Schenkel gleich dick ausgebildet.These thicker strips are located on each of the legs. They are preferably located approximately at the same height as the legs. These strips are preferably approximately twice as thick or more than twice as thick as the adjacent region of the leg to which they are attached. The two legs are preferably of the same thickness.
Der mindestens eine Streifen erstreckt sich vorzugsweise über die gesamte Länge des Dichtungsprofils, wobei er vorzugsweise keine Unterbrechungen aufweist. Vorzugsweise weist er über die gesamte Länge des Dichtungsprofils denselben Querschnitt auf.The at least one strip preferably extends over the entire length of the sealing profile, wherein it preferably has no interruptions. It preferably has the same cross section over the entire length of the sealing profile.
Diese Form zeigt auf dem Prüfstand überraschenderweise sehr gute Schallschutzwerte, welche sich wesentlich von den bisher verwendeten Dichtungen unterscheiden. Dies insbesondere dann, wenn die Dichtung eine automatische Absenkdichtung mit einem bekannten federbelasteten Absenkmechanismus ist. Typische gemessene Schalldämmwerte liegen bei 54 bis 56 dB im Vergleich zu 46 bis 50 dB der bekannten Dichtungen. Türen mit einfachen Dichtungen weisen üblicherweise Schalldämmwerte von circa 27 dB auf. Schalldämmwerte von Backsteinmauern liegen typischerweise bei circa 55 dB. Je höher der Messwert ist, umso besser ist der Schallschutz.Surprisingly, this shape shows very good sound insulation values on the test stand, which differ significantly from the seals used up to now. This is particularly the case when the seal is an automatic lowering seal with a known spring-loaded lowering mechanism. Typical measured sound insulation values are 54 to 56 dB compared to 46 to 50 dB of the known seals. Doors with simple seals usually have sound insulation values of around 27 dB. The sound insulation values of brick walls are typically around 55 dB. The higher the measured value, the better the sound insulation.
Die genannten Werte werden insbesondere bei Dichtungen erzielt, wie sie nachfolgend in allgemeiner Form beschrieben sind und insbesondere, wie sie in den nachfolgenden detailliert beschriebenen und in den Figuren dargestellten Ausführungsformen offenbart sind.The stated values are achieved in particular in the case of seals as described in general below and in particular as disclosed in the embodiments described in detail below and shown in the figures.
Vorzugsweise verläuft mindestens einer der Streifen beabstandet zur Unterseite der Trägerschiene. Vorzugsweise verlaufen alle Streifen beabstandet zu dieser Unterseite. Dies bezieht sich auf den angehobenen oder unbelasteten Zustand der Dichtung.
