Description

[0001] The present invention relates to a seal for fastening in or on a door or gate opening, in particular on a frame of a door or gate, hereinafter referred to as the first seal, and for interacting with a second seal which is installed in a door leaf or gate leaf.

[0002] It is known to use secondary seals to close gaps between the door leaf and the door opening in a wall. Such gaps are particularly common at the bottom of hinged doors. With floor-to-ceiling hinged doors, these gaps can also occur at the top. With sliding doors, they can even appear on the sides of the door leaf. Primary seals of the type mentioned above are used in doors to create a tight seal between the sealing profile of a secondary seal attached to or within the door leaf and an area of ​​the door opening. This is particularly useful when the sealing profile of the secondary seal is shorter than the length of the gap it is intended to close.The second seal can have a movable sealing strip with a sealing profile that is pressed against a sealing surface of the door opening (floor, ceiling, wall, reveal, or frame) when the door is closed (automatic door seal). However, it can also be a seal with a sealing profile that is fixed relative to the door leaf, such as a ramp seal or a sliding seal.

[0003] The second seal and first seals, as described above, can also be used on a gate, in particular on a swing gate or a sliding gate.

[0004] Currently, solid blocks, usually made of an elastomer, are used as the first seal. These first seals are generally less elastic than the sealing profiles of the second seals. Therefore, when closed, the ends of the second seal's sealing profiles often buckle or fold over when they come into contact with the surface of the first seal. This can have the disadvantage that, when the door or gate is closed, the end of the sealing profile is not in complete contact with the surface along its entire length. This can then potentially allow, albeit to a small extent, drafts, sound transmission, smoke transmission, or water ingress between the two sides of the door or gate.

[0005] A first seal with such a solid elastomer block is described in document DE 20 2016 101 143 U1. The elastomer block could be an elastic sealing element. An element with mounting holes forms the fastening part of this first seal. Although document DE 20 2016 101 143 U1 shows a corner seal, it is not possible to clearly distinguish between a sealing element and an elastic element.

[0006] The document US 2015 / 152 679 A1 shows in the Figures 1 to 5 Document US 2015 / 152 679 A1 describes a first variant that, at first glance, appears to be a type of folded seal that could abut one end of a drop seal. The disclosure of this seal in document US 2015 / 152 679 A1 is not unambiguous, leaving doubt as to whether this folded seal abuts a sealing profile of a drop seal or not. This applies in particular to the second embodiment described in document US 2015 / 152 679 A1.

[0007] The significance of document US 2,922,202 A regarding a first seal does not extend beyond that of document US 2015 / 152,679 A1. Document US 2,922,202 A does not indicate that a sealing profile of the drop seal rests against the rebate seal.

[0008] The invention is based on the objective of achieving an improvement in the sealing between the first and the second seal when the door or gate is closed.

[0009] This problem is solved according to the invention by a first seal having the features of claim 1. The first seal according to the invention is designed such that it has a fastening part for fastening the first seal in the door or gate opening, it has a sealing part for sealing contact with a sealing profile of the second seal, and it has an elastic part which allows movement of the sealing part of the first seal relative to the fastening part of the first seal when an end of the sealing profile of the second seal comes into contact with the sealing part of the first seal or when the end of the sealing profile is released from the sealing part, wherein the fastening part is formed by a plate, wherein the elastic parts are plate-like, and wherein the sealing part is essentially formed as a plate.

[0010] The inventive design of the first seal, comprising a fastening element, a sealing element, and an elastic element, allows the first seal to yield or retract when the door or gate is closed. The end of the sealing profile of the second seal can then conform to the sealing element of the first seal without folding or bending, or at least with less folding or bending. This improves the effectiveness of the seals.

[0011] The second seal can be an automatic seal with a sealing strip that encompasses the sealing profile. The sealing strip can be moved relative to a housing of the second seal by a mechanism, in a direction perpendicular to the extension of the sealing strip. Depending on where the seal is attached to the door or gate leaf, this movement can be up and down or sideways in opposite directions.

[0012] A first seal according to the invention can consist of a single piece. This piece can consist of one or more components, in particular two components. These components can differ, for example, in their elasticity. For instance, the component chosen for the elastic part can have a higher elasticity than a component chosen for the fastening part and / or the sealing part.

[0013] Higher elasticity of the elastic part compared to the fastening part and / or the sealing part can be achieved not only by using components with different elasticities. For example, higher elasticity of the elastic part can also be achieved by designing it in such a way that it can compress. In this case, the first seal can also consist of a single component.

[0014] One component, or at least one of the several components, can be an elastomer. It is possible that the elastomer forms at least a section of the elastic part of the first seal, or that the elastic part of the first seal is made entirely of the elastomer.

[0015] If the seal consists of two components, it can be manufactured using a 2K injection molding process. Therefore, the seal can be a 2K part.

[0016] It is also possible that the seal is not made from a single piece, but consists of several pieces that are connected to each other, and in particular, that are detachably connected. For example, the elastic part could be a spring element that is connected to the fastening part on one side and to the sealing part on the other.

[0017] The sealing part of a first seal according to the invention can have a largely flat contact surface, regardless of whether the seal consists of one or more pieces, against which the end of the sealing profile of the second seal rests.

[0018] The sealing element of a first seal according to the invention can have at least one drainage element for diverting water away from the contact surface. If the first seal is attached, for example, to the lower end of a rebated exterior door, water that has penetrated a rebate of the door can run down the rebate. It then encounters the drainage element and is directed out of the rebate to the outside by it, so that the water cannot collect at the lower end of the rebate and / or possibly collect on the inside of the second seal. The drainage element can project beyond the contact surface in a direction away from the elastic part. This makes it possible for a free end of the drainage element to contact a side surface of the door and seal with this side surface. Preferably, the drainage element can have a drainage surface that is oriented obliquely to the contact surface, for example at an angle of 30 to 60°.

[0019] The mounting surface can have an upper edge when installed in or on a door opening, to which the drainage element is attached, this upper edge being inclined in the first seal when installed in or on the door opening. This inclination allows water striking the drainage element to be diverted in a specific direction.

[0020] Furthermore, the mounting surface can have a lateral edge when installed in or on a door opening, to which a further drainage element is attached, connected to the drainage element at the upper edge. This additional drainage element allows the water flowing from the first drainage element to be directed further in a specific direction. Moreover, this additional drainage element can prevent water from penetrating the area where the end of the sealing profile of the second seal and the first seal meet from other directions.

[0021] The fastening element of a first seal according to the invention can have a contact surface which, when the first seal is mounted in or on the door opening and the door is open, is not parallel to the bearing surface of the sealing element. Such an inclination can be particularly advantageous for hinged doors. When the door is closed, the end of the sealing profile of the second seal can then run against the bearing surface, which is not aligned parallel to the contact surface and is thus inclined. The end of the sealing profile can thus cause the elastic part of the first seal to compress. This causes the sealing element to retract and provides space for the end of the sealing profile of the second seal, which consequently does not buckle or fold over, or only does so minimally.

[0022] Further features and advantages of exemplary embodiments of the invention are described below with reference to the drawings. The same reference numerals are used for identical or similar parts and for parts with identical or similar functions. The drawings show: Fig. 1 a perspective view of the first poem, Fig. 2 a view of the first seal from the front, Fig. 3 a view of the first seal from the rear, Fig. 4 a view of the first seal from above, Fig. 5 A view from below of the lower end of an arrangement consisting of a door, the first and second seals in the closed state of the door. Fig. 6 a perspective view of the lower end of the arrangement Fig. 5 , Fig. 7 a view like in Fig. 6 , however without a door and second seal and Fig. 8 a view like in Fig. 6 and 7, however without a door and second seal, and with the first seal in a state with the door open.

[0023] It is not necessary for a first seal according to the invention to have all the features described below. It is also possible for a first seal according to the invention to have only individual features of the embodiment described below.

[0024] The illustrated seal 1 according to the invention is manufactured in one piece. It consists of an elastomer as an elastic plastic component.

[0025] The first seal 1 has a fastening element 11. This element is formed by a plate. A through-hole 17 is provided in this plate. A screw can be inserted through this through-hole 17, allowing the plate, and thus the entire first seal 1, to be fastened to a frame or other part of a door opening. For this purpose, the fastening element 11 can be placed against the frame or other part with a contact surface. The screw is then screwed through the through-hole 17 into the frame or other part.

[0026] The first seal 1 has two elastic parts 12 connected to one side of the fastening part 11 opposite the contact surface. The elastic parts 12 are plate-like and inclined relative to each other and to the fastening part. One of the two elastic parts 12 is shorter than the other.

[0027] The first seal 1 further comprises a sealing element 13. This is essentially designed as a plate and is connected to the ends of the elastic parts 12. One side of the sealing element 13 facing away from the elastic parts 12 has a flat contact surface. Because the two elastic parts 12 are not of the same length, the contact surfaces of the sealing element 13 and the contact surface of the fastening element 11 are not parallel to each other.

[0028] Drainage elements 14 and 15 are attached to an upper edge and a lateral edge of the contact surface of the sealing element 13, enabling water to be diverted away from the contact surface. The drainage elements 14 and 15 project beyond the contact surface in a direction away from the fastening element 11. The drainage elements 14 and 15 are angled relative to the contact surface.

[0029] The contact surface of the sealing element 13 of a first seal 1 according to the invention could be rectangular. In the illustrated example, it is not, but trapezoidal. The lateral edges are parallel to each other, and the lower edge is at a right angle to the lateral edges. However, the upper edge is not parallel to the lower edge. Rather, it is inclined towards the lateral edge to which one of the drain elements 14 is attached. The lateral edge to which the other drain element 15 is attached is shorter than the opposite edge.

[0030] The sealing element 13 has a through-hole 16 located approximately in the center of its contact surface. The diameter of this hole 16 is slightly larger than the diameter of the through-hole 17 in the fastening element 11. The two through-holes 16 and 17 are aligned, provided the elastic parts 12 are not deformed. A screw, including its head, can be passed through the through-hole 16 in the sealing element, allowing the fastening element 11, and thus the entire first seal 1, to be screwed onto or into a door opening, as shown in the Figures 5 to 8 is shown.

[0031] The first seal 1, in conjunction with a second seal 2 and third seals 3, forms a continuous seal to close gaps between the frame 4 and the floor on one side, and the door leaf 5 on the other. In this example, the second seal 2 is an automatically lowering bottom seal attached to the lower edge of the door leaf 5. Instead of an automatic door seal 2, another type of bottom seal could be used, such as a threshold seal or similar. The third seals are rebate seals inserted into the rebate of the frame.

[0032] The second seal 2 has a sealing profile 21 that rests against the floor when the door is closed. Ends of this sealing profile 21 extend laterally beyond the door leaf 5 and abut the first seals 1, which are mounted at the lower ends of the frame 4 in the rebate area. The first seals butt against the floor and the third seals 3. This allows the lower corner areas of the door to be sealed.

[0033] The door leaf 5, or at least the ends of the sealing profile 21 projecting beyond the door leaf 5, abut the contact surface of the sealing element 13 of the first seals 1 according to the invention, causing the elastic elements 12 of the first seals 1 to compress and be tensioned. When the door is open, no pressure is exerted on the sealing element 13 of the first seals 1, and the elastic elements 12 of the first seals 1 are then relaxed (see Fig. 8 ).
