SEALING UNIT FOR A SLIDING DOOR

Description

TECHNICAL AREA

[0001] The present invention relates to a sealing unit for a door or window, in particular for a sliding door or a sliding window, and in particular a vertical sealing unit. STATE OF THE ART

[0002] Movable door leaves, especially sliding doors, are typically sealed against the door frame or wall element when closed. This is achieved, among other things, by vertically oriented sealing profiles that seal the gap between the door leaf and the door frame or wall element. These sealing profiles usually have a fastening structure that clamps into a groove in the door leaf, door frame, or wall element. This is shown, for example, in EP 3 388 608 A1 and DE 20 2017 104 445 U1.

[0003] EP 3 489 448 A1 discloses a seal that is also held in a groove of the movable door leaf. This seal has a mounting profile for fastening in the groove of the movable door leaf and a sealing profile. The sealing profile has mounting ridges that are elastically pre-tensioned and inserted into grooves of the mounting profile. A profile rail is also arranged on the door frame, against which the sealing profile is pressed by means of a magnetic strip when the door is closed.

[0004] However, it is not always desirable to create a groove in the door leaf or other components of the sliding door. A groove facilitates moisture penetration into the door leaf and reduces sound insulation. Furthermore, creating a groove in the door leaf is time-consuming.

[0005] EP 3 480 408 A1 and DE 10 2008 000565 A1 disclose mounting profiles with seals which protrude laterally from the sealing profile. PRESENTATION OF THE INVENTION

[0006] It is therefore an object of the invention to create a sealing unit that does not require a groove for attachment to the door or window and that can be used in particular as a vertical seal for sliding doors.

[0007] This problem is solved by a sealing unit with the features of claim 1.

[0008] The sealing unit according to the invention comprises a mounting profile for attaching the sealing unit to a door or wall element and a sealing profile for sealing a gap between a movable door leaf or door wing and a door frame of the door or a wall element. The mounting profile has a rear surface for contact with the door. The sealing profile has a retaining element, and the mounting profile has a recess for receiving the retaining element. The recess is closed on a front surface of the mounting profile opposite the rear surface.

[0009] The terms door leaf and door panel are used synonymously in this text to refer to the part of the door that is moved to close the doorway. Particularly in the case of sliding doors, the door leaf is often referred to as the door panel.

[0010] The mounting profile can be glued, screwed or otherwise attached to the desired building element without the need for a groove in the building element, e.g. in the door leaf or door wing.

[0011] The sealing profile can be easily positioned in the recess. This simplifies installation.

[0012] The sealing profile is preferably not attached to the door or wall element itself, but rather secured to the door or wall element by the mounting profile. This allows the sealing profile to be easily replaced if necessary. If the mounting profile is open at the top or bottom of the recess, the sealing profile can simply be pulled out of the recess by hand. With sufficient space, this can even be done with the door leaf installed. If the recess is closed at the top and bottom, the mounting profile can preferably be removed, and the sealing profile taken out and replaced. The same mounting profile can then be reattached to the door or wall element with the new sealing profile.

[0013] The retaining element preferably has a spring-loaded part that is held in place by the mounting profile when the sealing unit is mounted on the door or wall element. The remaining part of the sealing profile, in particular the sealing lip that closes the gap, can be shaped as desired. This increases the flexibility in the design of the sealing profile.

[0014] Preferably, the sealing profile protrudes laterally from the mounting profile. This allows the sealing unit to be designed with a relatively narrow profile.

[0015] In preferred embodiments, the sealing profile can be clamped between the mounting profile and the door or wall element by means of the mounting profile.

[0016] Preferably, the retaining element is a leg projecting at an angle from the base of the sealing profile. The leg is preferably resilient.

[0017] Preferably, the recess is open towards the back of the mounting profile.

[0018] However, the recess can also be open towards the front of the mounting profile and covered by a closable cover of the mounting profile. The cover can, in particular, be designed as a hinged element.

[0019] In some embodiments, the sealing profile can be clamped within the mounting profile, with a portion of the mounting profile being designed to pivot or fold. Preferably, the mounting profile has a movable locking element to close the recess towards the rear of the mounting profile.

[0020] Preferably, the mounting profile has a flat base body and a web arranged laterally on the base body, the web being thinner than the base body. This allows the recess to be formed easily and manufactured cost-effectively. The mounting profile can be flat on its front side, with a subtle design, or, if desired, with decorative elements.

[0021] Preferably, the web has a retaining lug facing the rear of the mounting profile, with the retaining lug ending at a distance from the rear. This retaining lug prevents the sealing profile from being pulled laterally out of the recess and thus out of the mounting profile when the seal is installed. In other embodiments, however, no retaining lug is present, and the contact pressure of the web on the retaining element of the sealing profile and / or the spring force of the retaining element is sufficient to hold the sealing profile in its installed position.

[0022] According to the invention, the sealing profile has a base on which a sealing lip and the retaining element are arranged, the sealing lip projecting beyond the mounting profile when the sealing unit is installed. The sealing lip serves to seal the gap between the movable door leaf and the door frame, or between the movable door leaf and the wall element. The door leaf is preferably part of a sliding door and is therefore movable. The sealing lip preferably projects beyond the base at an angle, extending laterally over at least a portion of the width of the mounting profile. Preferably, the sealing lip is resilient.

[0023] Preferably, the base has a first contact surface for attachment to the door or wall element.

[0024] Preferably, the sealing lip and / or the retaining element is designed to be spring-loaded.

[0025] The sealing unit according to the invention is particularly suitable as a vertical seal for a sliding door. However, other applications are also possible.

[0026] Further embodiments are specified in the dependent claims. BRIEF DESCRIPTION OF THE DRAWINGS

DESCRIPTION OF PREFERRED EXECUTION FORMS

[0028] Figure 1 Figure 1 shows a typical sliding door with a sliding door leaf F, which is slidably arranged in a wall element W by means of a sliding door guide S. The sliding door is shown in the closed position. The opening direction is shown in Figure 1 represented by an arrow.

[0029] Vertical seals D are arranged on the sliding door leaf F or the wall element W in the area of ​​both longitudinal edges of the sliding door leaf F. The position of these vertical seals is indicated by an arrow in the figure. The vertical seals D are concealed by the door leaf F and are therefore not visible. The vertical seals D preferably extend over the entire height of the sliding door leaf F.

[0030] In the Figures 2 to 5 A first embodiment of a sealing unit according to the invention is shown, which is suitable for use in a sliding door according to Figure 1 suitable. Figures 6 and 7 show another embodiment which is also suitable for this purpose.

[0031] As in the Figures 2 and 3 As can be clearly seen, the sealing unit has a sealing profile 1, a mounting profile 2 and a fastening means, here in the form of at least one adhesive tape 3.

[0032] The mounting profile 2 is preferably rigid. It is preferably made of metal, preferably aluminum. It is preferably formed in one piece. It typically, but not necessarily, has a cross-section that remains constant over its entire length.

[0033] The mounting profile 2 has a flat base body 20 with a rear surface 200 facing the door leaf F or the wall element W. The rear surface 200 is preferably flat and forms a contact surface for contact with the building element to which the mounting profile 2 is to be attached. In this example, the rear surface 200 is adhered to the surface of the door leaf F using adhesive tape 3 in the form of double-sided tape.

[0034] The mounting profile 2 has a web 21 that projects laterally beyond the base body 20. Preferably, the upper surface of the web 21 is flush with a front face 201 of the base body 20. Preferably, the front face 201 is planar. Preferably, it runs parallel to the rear face 200.

[0035] The web 21 has a smaller thickness than the base body 20. It thus forms a recess 23 open towards the rear side 200. Preferably, but not necessarily, a downwardly projecting retaining lug 22 is formed at the end of the web 21. The retaining lug 22 terminates at a distance from the rear side 200 of the base body 20. That is, its length is less than the thickness of the base body 20. The retaining lug 22 thus forms a lateral boundary for an upper region of the recess 23.

[0036] The web 21 and, if present, the retaining lug 22, preferably extend over the entire length of the mounting profile 2. The end of the mounting profile 2 opposite the web 21 can be designed as desired.

[0037] The sealing profile 1 is preferably made of an elastic material. It is preferably made of silicone or other elastomers. It may have areas with different Shore hardnesses or areas made of materials with different hardnesses. In other embodiments, the Shore hardness is uniform.

[0038] Preferably, the sealing profile 1 is formed in one piece. It preferably has a cross-section that remains constant over its entire length.

[0039] The sealing profile 1 is preferably the same length as, or slightly longer than, the mounting profile 2. It therefore preferably extends at least over the entire length of the mounting profile 2.

[0040] The sealing profile 1 has a base 11, which is preferably angled. A sealing lip 10 is formed on the base 11, specifically on one leg of the angle. The sealing lip 10 is resiliently connected to the base 11 via a tapered section 13. The tapered section 13 preferably forms a hinge.

[0041] The sealing lip 10 extends in the assembled state of the sealing unit at an angle of less than 90°, preferably from about 30° to 60° and even more preferably from about 45°, with respect to the rear side 200 of the mounting profile 2 and thus the door surface.

[0042] The sealing lip 10 can have different shapes. In this example, it has a thickening at its free end and is preferably approximately the same thickness over its remaining area. It extends over at least part of the width of the mounting profile 2.

[0043] A stretching thread 14 is preferably arranged in the base 1, which prevents the sealing profile 1 from contracting in length.

[0044] At the other end of the base 11, here at the second angle, a retaining element 12 is formed. In this example, this is a leg that also projects obliquely upwards or outwards.

[0045] The retaining element 12 is received in the recess 23 of the mounting profile 2 when assembled. This is shown in Figure 3 Clearly visible. The retaining element 12, here the leg, has a free end which, in this assembled state, abuts the inner wall of the web 21. Figure 3 This does not accurately depict the situation. In this state, the retaining element 12 is compressed and wedged between web 21 and the surface of the door leaf F or the wall element W.

[0046] The underside of the base 11 of the sealing profile 1 is preferably flat and forms a first contact surface 110 for resting on the door leaf F or the wall element W. A side wall of the base 11 adjacent to the retaining element 12 forms a second contact surface 111 for contact with the inner wall of the recess 23 formed by the base body 20. The free end of the retaining lug 22 of the mounting profile 2 preferably presses against a surface of the base 1 and thus presses it against the door leaf F.

[0047] The base 11 also has a rib 15 on the side opposite the retaining element 12, projecting obliquely towards the door leaf F. This serves as a spreader and simplifies the clamping of the sealing profile 1 by means of the mounting profile 2.

[0048] In the Figures 4 and 5It is evident how the sealing unit according to the invention can be attached to a door leaf or another surface. First, the double-sided adhesive tape 3 is applied to the surface. Then, the retaining element 12 of the sealing profile 1 is inserted into the recess 23 and pressed onto the surface together with the mounting profile 2. This adheres the mounting profile 2 and clamps the sealing profile 1 between the surface and the web 21 of the mounting profile 2. Preferably, the sealing profile 1 does not contact the adhesive tape 3. The adhesive tape 3 can extend in one piece over the entire length of the mounting profile 1. However, it can also consist of two or more separate sections spaced apart from each other along the length of the mounting profile 1.

[0049] In the Figures 6 and 7 One variant is shown. The sealing unit is designed identically to the one described in the... Figures 2 to 5described unit. In contrast to this unit, the mounting profile 2 is screwed to the door leaf F or to the surface. For this purpose, the mounting profile 2 has at least two through holes 24. A hole 5 is also required in the surface. The screw is designated with reference numeral 4 in the figures. An advantage of this embodiment is that the mounting profile 2 can be easily removed when the sealing profile needs to be replaced. However, a disadvantage is that in this case at least two holes 5 are required in the door.

[0050] The sealing unit according to the invention enables the installation of a seal without the use of grooves. It also allows for easy installation and replacement of seals. REFERENCE MARK LIST
