Definitions

  • the invention relates to a door seal, in particular a door seal. It includes a fastener for attachment to the door, a seal retainer, a lowering mechanism unit which mechanically couples the fastener to the seal retainer and which is configured to lower the seal retainer from a raised to a lowered position and, conversely, raise from the lowered to the raised position and a seal member fixed to the seal receiving member and extending in a longitudinal direction.
  • Door seal in particular door seals, of this type are used to seal doors along their lower edge air and soundproof against the ground. Through such a door seal soundproofing can be achieved and fire protection regulations are met by avoiding the passage of air and smoke.
  • the following is spoken of door seal, even if the seal is to seal the upper gap of the door and ceiling or upper side of the door frame.
  • the term "door seal” therefore also includes door seals in the following, which do not seal against the floor but the ceiling.
  • An essential feature of such door seals is their lowering mechanism, which causes the seal is raised over the largest movement section when opening and closing the door and thereby does not drag on the floor. Only in a range of movement shortly before reaching or shortly after leaving the closed position, the seal is lowered and pressed against the ground or raised. This movement is effected by a lowering mechanism, for example, by means of an arranged on the side edge of the door actuating lever or the like.
  • the button can be arranged, for example, in the case of pivotally mounted doors on the hinge or hinge side, and correspondingly be placed on the lock side in the case of sliding doors.
  • a door seal of such a construction is off EP1162341B1 and EP1460232B1 known.
  • a first problem of the devices according to the prior art is that the lowering mechanism, in particular in a long Absenkrange the door seal this does not move on an exactly vertical path, but instead also a horizontal component of movement occurs in the longitudinal direction of the seal.
  • this problem occurs in robust lowering mechanisms, which are operated by one or more pivoting lever and in which was preferably omitted for longevity on linear guides with a correspondingly high wear in a lowering mechanism.
  • this horizontal movement component but it can come to air gaps laterally adjacent to the seal, which affect the sealing effect over the entire bottom gap.
  • leaf springs operated seals or seals with little or no lateral displacement have the problem that the gap between the door and frame can not be sealed sufficiently. It is a first object of the invention to provide a door seal which overcomes this disadvantage.
  • a second object of the invention is to provide a door bottom gasket which can be functionally better integrated into the overall gasket system of a door and simplifies installation.
  • a door seal seals both reliably against smooth floors, but at the same time also achieves this sealing effect in case of bumps and soil contamination.
  • the sealing arc can, for example, according to EP 1 122 394 be educated.
  • the sealing lip can be as explained below or as EP 1 905 938 be educated.
  • the two sealing lines may seal a single common area or different areas; i.e. the first sealing line can seal against the floor or the ceiling and the second sealing line can seal against the side frame of the door.
  • the second sealing element section is preferably formed by a sealing leg arch, in particular a rolling seal.
  • the door seal according to the invention uses the advantages of a first sealing element section, which is fastened exclusively in the seal receiving element and which thus moves with respect to the fastening element, with a second sealing element section in the form of a rolling seal.
  • the first sealing member portion is preferably lowerable and raisable with a full lowering stroke of the lowering mechanism unit, the lowering stroke defining a height, and wherein the second side of the second sealing member portion is mounted at a lesser height than the first sealing member portion along the path when raised.
  • the mechanism is preferably spring loaded.
  • it has leaf springs which extend in the longitudinal direction of the seal and which are attached at one end to an actuating rod, at another end to the housing of the seal and with a central region on the liftable and lowerable, the sealing element bearing sealing strip, attached here are.
  • the actuating rod can be displaced in the longitudinal direction of the seal by means of a control knob on one side projecting the seal housing.
  • the operating rod also becomes particularly in the case of a flat bar Called slider.
  • a sliding block which acts as an actuating rod.
  • the housing is also referred to in this text as a fastener, the carrier or sealing strip as a seal receiving element.
  • the second sealing element section can be lowered or raised by means of the lowering mechanism with a fractional part, in particular half of the lowering stroke of the lowering mechanism unit.
  • the second side of the second sealing element section is arranged laterally offset transversely to the longitudinal direction for attachment of the first sealing element section.
  • the two sealing element sections may be formed as separate sections. However, they are preferably connected to each other. Preferably, they are formed integrally together. The entire sealing element is preferably formed in one piece.
  • a door seal of the aforementioned construction by the sealing element by a first sealing element portion which is lowered by means of Absenkmechanikech with a full Absenkhub the Absenkmechanikech or raised, provides a first sealing line and by a second seal member portion formed by a seal leg arc, one side of which is lowered by the lowering mechanism and the other side fixed in position opposite to the fastener, providing a second seal line parallel to the first seal line, the second seal member portion by means of the lowering mechanism is lowered or raised at a fraction, in particular half of the Absenkhubs the Absenkmechanikmaschine.
  • the invention provides a door seal which is characterized by two spaced seal lines when the door base seal is lowered and seals against the floor / threshold.
  • the two seal lines are kinematically biased in such a manner that the first seal line is moved at the full stroke of the upward and downward movement of the lowering mechanism unit, whereas the second seal line is formed on a seal leg arc which is moved on one side at the full stroke but at the other cross-sectional side is fixed with respect to the fastener or the door.
  • the second seal line typically moves with half the movement stroke.
  • the door seal according to the invention allows by this design a double and different sealing effect, which is superior to seal designs with two seal lines conventional design.
  • the seal according to the invention it becomes possible to provide a sealing effect which can be achieved over a wide stroke range to compensate for unevenness and at the same time to achieve a sealing effect with a high contact pressure over a shorter stroke range.
  • the seal according to the invention thus achieves an ideal sealing effect in the usually achieved assembly window with a bottom air of approximately 7 mm, which is also insensitive to soiling and floor distortions or other unevenness.
  • a great tolerance for assembly inaccuracies with deviations from the ideal bottom-air measure up or down is achieved with the seal according to the invention.
  • the floor seal according to the invention may also be designed so that the first sealing line is formed on a sealing portion formed of a different material than a sealing portion on which the second sealing line is formed.

  • the different elasticity of the seal in the region of the first and second seal line can also be achieved by means of corresponding geometric configurations of the seal, wall thicknesses of the seal or the like. Decisive for the effect according to the invention is the fact that the first sealing line is designed such that it exerts a lower elastic counterforce to a force acting in the direction of movement of the seal than does the seal in the region of the second sealing line.
  • the second sealing line is not fastened at its one leg end to the movable component of the door base gasket, but instead can be fastened independently of the lowering mechanism.
  • This makes it possible to fix this second end of the sealing leg arch, for example, directly in the edge region of the lower door edge or on the fastening element and thereby to offset the second sealing line in the plane of the sealing abutment plane between the door and door frame or at least immediately adjacent to this seal abutment plane between the door frame and door.
  • the disadvantage of known door seals have an offset of the sealing line of the door base seal to the sealing abutment level between door frame and door of 10 mm and more overcome, and the consequent air gap, which forms each on the sides of the door on both the hinge side and the lock side of the door, or avoided at least significantly reduced.
  • another advantageous aspect of the door base gasket according to the invention that it is possible by the one-sided fixation of the sealing leg bow and running on the other side attachment of the sealing leg bow on the lowering mechanism, a horizontally acting transverse force which acts perpendicular to the longitudinal axis of the seal, upon impact of the Apply second seal line to the floor or threshold to the seal.
  • This transverse force can bring about an advantageous contact force perpendicular to the longitudinal axis within the door base seal between seal and lowering mechanism or seal receiving element or fastener, whereby the sealing effect against sound passing through the door seal itself, air draft and the like. Significantly increased.
  • the advantage here is that this increase in the sealing effect is achieved only when hitting the second sealing line on the ground, so that the ease of lowering and lifting movement is not affected thereby.
  • the first and second sealing lines preferably run parallel and at a distance from one another. They preferably extend over the entire length of the seal, but the scope of the invention also includes variants in which one or both seal lines are interrupted in places, in particular even if this could be caused by unevenness of the soil.
  • the sealing leg arch is curved convexly outwards when the seal is lowered, this curvature being changed by the contact with the ground, for example being squeezed and may be arched back inwards into a concave shape.
  • the sealing element itself can be made in one piece or in two parts. Preference is given to a one-part embodiment which, by means of coextrusion or other production methods, can also be embodied in the form of a one-part seal made of two different materials.
  • the sealing element may alternatively be composed of two or more elements each extending completely over the entire length of the gasket or joining one another longitudinally. These multiple elements, which form the sealing element, can be connected to one another, for example glued, or preassembled in some other way, and these elements can also be assembled in the course of assembly of the seal only to the sealing element.
  • the lowering mechanism may in particular comprise a plurality of mechanical parts such as levers, rails, operating buttons and the like, which in particular implement the closing movement of the door in cooperation with the frame in a vertical lowering movement and vice versa, the opening movement of the door in a vertical upward movement of the sealing element.

In this groove rail on the sealing element 250 above the hollow chamber profile 253 formed, introduced in cross-section t-shaped longitudinal structure and ensures a positive attachment of the sealing element 250 on the seal receiving element 240th
  • the sealing member 250 of the third embodiment does not have an upstanding leg folded over at its end, as in the two previous embodiments for attaching the sealing member. Instead, only on the side facing away from the stop side of the door, a single leg 251 is formed, which is not turned over at its upper end, but ends with a chamfer. This single leg serves to provide a sealing action between the gasket receiving member 240 and the fastening member 220, thus preventing the sealing lines which form the gasket member from becoming bottomed out.
  • FIG. 6 shows a fourth embodiment of the door seal according to the invention, which differs from the previously described third embodiment in two functional aspects.
  • the fastener 320 of this fourth embodiment is designed with shorter legs, so that the unilaterally executed sealing leg 351 of the sealing member 350 does not seal against the fastener, but instead against the side wall of the groove 312, which in the lower edge of Door is introduced.
  • the side leg 351 is therefore designed in this embodiment with greater wall thickness than in the previously described third embodiment.
  • the fourth embodiment is equipped with no hollow section and molded lip for forming the first sealing line. Instead, extends immediately below the seal receiving member 340 of the t-shaped longitudinal portion which serves for the positive anchoring of the sealing element, an obliquely downward sealing lip 353, which forms the first seal line at its lower end.
  • the fastener and the gasket-receiving member of the embodiments of the invention may be fabricated as an extruded profile, such as an aluminum extruded profile, whereby high corrosion resistance and sufficient strength can be provided.
  • the fastening element and / or the seal receiving element are made of a folded sheet metal profile made of aluminum, steel or plastic.
  • the embodiments of the FIGS. 7 and 8 show examples of door seals of such embodiment.
  • FIG. 7 shows a fifth embodiment of the invention.
  • the fastener is not designed as an extruded profile, but instead as a sheet metal profile, such as aluminum or plastic profile or rollformed steel profile.
  • the fastening element 420 has a bottom section 421 in cross-section, which has laterally bent end regions 422a, b on both sides in a radius of about 180 °, which in turn form a groove rail for receiving the lowering mechanism unit 430. Starting from the curved end portions, the fastener is then provided with two oppositely folded legs 423, 424 on both sides, which extend obliquely outwards down.
  • the aluminum, plastic or steel profile, which serves as a fastening element 420 also has a cross-sectionally U-shaped structure.
  • the fastener is also designed as a roll-formed aluminum, plastic or steel profile, consisting of a thin sheet metal section by two executed at the top in both corners 90 ° folds, two executed at the ends of the legs 180 ° bevels, two inwards directed 90 ° -Abkantept and two executed each 180 ° bevels a corresponding profile in cross-section of the fastener 320 520 is formed.
  • the fastening element 520 according to FIG. 8 functionally has the same properties as the extruded profile 320 of the fourth embodiment according to FIG. 6 ,
  • the seal receiving member 540 is also designed as an aluminum or plastic profile or roll-formed steel profile. It is this by two at the base laterally executed 90 ° bevels, two at the end of the leg 180 ° bevels and two executed to form the groove rail for receiving the t-shaped longitudinal portion 90 ° bevels executed at the inwardly directed ends 180 ° bevels executed, thereby forming the seal receiving member 340 of the fourth embodiment.
  • FIG. 9 shows the sealing element 50, which in the first embodiment according to FIG. 3 is used.
  • FIG. 10 shows the sealing element 150, which in the second embodiment according to FIG. 4 is used.
  • FIG. 11 shows the sealing member 250 used in the third embodiment.
  • FIG. 12 shows the sealing member 350 used in the fourth, fifth and sixth embodiments.
  • FIG. 13 a diagram is shown, which explains an example of an embodiment of a door seal of the construction according to the invention in its lowering sequence of the two sealing lines.
  • the first sealing plane which corresponds to the sealing line 54a according to FIG. 3 is in the raised position 4 millimeters above the position of the second seal line, the seal line 55a of the FIG. 3 equivalent.
  • the planes defined by these sealing lines are offset parallel to one another and extend over the entire length of the door base gasket.
  • the lowering mechanism unit may perform a total stroke of 24 millimeters, resulting in a distance of 24 millimeters of the first seal line and a distance of 12 millimeters of the second seal line at C.
  • a maximum ground clearance ie a maximum distance between the lower edge of the door and the floor of 20 millimeters can be bridged with the door base gasket.
  • the sealing effect is achieved only by the first sealing line 54a.
  • the optimum sealing effect of the so-designed door seal is achieved in a soil air, which is between 4 and 12 millimeters. This is a practical assembly area that can be adjusted without much effort, ensures a reliable, free run of the door and achieved over the prior art significantly improved sealing effect by the two sealing lines with different contact pressure and position.
