Description

[0001] The presented invention relates to a sealing system and a door system for a pivot door, according to the attached claims.

[0002] Pivot doors are a special type of revolving door that differs fundamentally from carousel revolving doors, saloon doors or doors with push hinges and resembles pivoting wall elements.

[0003] Unlike hinged doors, pivot doors do not have fittings and hinges attached to the side of the door leaf, but rather embedded in the door leaf at a central or asymmetrical pivot point.

[0004] In a pivot door, the door leaf is typically constructed as a vertical and rigid plane that pivots around a predetermined vertical axis when pressure is applied, thus creating an opening. Therefore, handles or door levers are unnecessary.

[0005] The door leaves of pivot doors can be up to 6 meters high and up to 3 meters wide, significantly larger than conventional door leaves. For even wider openings, multiple pivot doors can be combined. A pivot door weighing up to 1,500 kg can be swung to an opening angle greater than 90 degrees.

[0006] Pivot doors are generally constructed as frames or skeletons, less often as monolithic elements such as solid wood door leaves. The range extends from frames with large glazed areas to sandwich constructions that can be used as both interior and exterior doors.

[0007] For pivot doors, correct closing, low maintenance requirements and long-term operational reliability depend significantly on the sealing system used.

[0008] Therefore, one of the objectives of the presented invention is to enable long-term and low-maintenance operation of a pivot door, especially in older buildings.

[0009] Thus, according to a first aspect of the presented invention, a sealing system for a pivot door is presented.

[0010] The presented sealing system comprises a first elongated base body, a second elongated base body, a rotary bearing, a separating element, a first seal, and a second seal, wherein the first base body is mechanically coupled to the second base body by the rotary bearing, the rotary bearing being configured to rotatably support a counter bearing of a pivot door, the separating element having a lower thermal heat transfer coefficient than the first and second base bodies, the separating element being arranged between the first and second base bodies, the first seal extending along a longitudinal axis of the second base body, and the second seal being movable between an open and a closed state.wherein, in the closed state, the second seal runs along a longitudinal axis of the sealing system and the rotary bearing is located both between the first seal and the second seal as well as between the first base body and the second base body.

[0011] The presented invention is based on a multi-part sealing system that provides a pivot bearing for the rotatable mounting of a pivot door. In the closed position of the pivot door, this pivot bearing is protected from environmental influences by two seals that together surround the pivot bearing on two sides, i.e., an outside and an inside of the pivot door.

[0012] In particular, the seals provided according to the invention minimize the ingress of driving rain into the pivot bearing or into a space between the two seals, so that the presented sealing system is particularly suitable for fastening pivot doors in the outdoor area.

[0013] Due to the multi-part construction of the presented sealing system with a first base body and a second base body, the sealing system can be applied particularly easily and quickly in old buildings or new buildings, in which, for example, a width or depth of the first base body and / or the second base body is selected according to the respective installation situation.

[0014] Furthermore, the first base body and the second base body are thermally separated from each other by the separating element provided according to the invention, so that a so-called "warm threshold" is created, i.e., the discharge of thermal energy from a heated interior into a cold environment, or conversely, the input of thermal energy from a warm environment into an air-conditioned interior, is minimized.

[0015] The presented sealing system comprises a second seal that is movable between an open and a closed state. In the closed state, the second seal runs along a longitudinal axis of the sealing system, in particular parallel to a longitudinal axis of the second base body.

[0016] The second seal is preferably arranged on a respective pivot door and is deflected together with the pivot door in the open state, and therefore does not run along the longitudinal axis of the sealing system.

[0017] It may be provided that the first seal comprises a magnetic strip deflectable in a receptacle of the first base body and a counter-magnetic strip for arrangement on the pivot door, wherein the magnetic strip is deflectable in such a way that it seals a gap between the pivot door and the first base body against an environment.

[0018] A deflectable magnetic strip, i.e., movable upwards towards a respective pivot door, seals the area between the pivot door and the first base body when required, i.e., in a closed position of the pivot door, and provides an essentially flat surface when required, i.e., in an open position of the pivot door, thus enabling safe or barrier-free passage across the surface or the sealing system.

[0019] It may also be provided that the second seal includes a flexible sealing lip configured to seal a gap between the pivot door and the second base body against an environment.

[0020] A flexible sealing lip, which is made of, for example, rubber or an elastic plastic, can in particular have a shape angled towards an environment, so that the angled shape provides a force that counteracts movement of the sealing lip towards the rotary bearing, for example by a gust of wind and / or presses the sealing lip against the first base body.

[0021] It may also be provided that the rotary bearing is screwed, glued, riveted and / or clamped to the first base body and / or the second base body.

[0022] The rotary bearing can be mechanically connected to the first base body and the second base body in any suitable way.

[0023] It may further be provided that the first base body includes a receptacle which secures the first seal movably in the first base body by means of a stop, wherein the receptacle is configured to receive the first seal in such a way that it forms a flat surface with the first base body.

[0024] A stop, such as an overhang in the first recess, prevents the first seal or its magnetic strip from being detached from the first base body.

[0025] To accommodate the first seal in such a way that it forms a flat surface with the first base body, the first receptacle can have a height that corresponds at least to the height of the first seal or its magnetic strip.

[0026] It may also be provided that the second base body includes a second receptacle configured to at least partially accommodate the second seal.

[0027] The second receptacle can, for example, be a channel into which the second seal is inserted when it is in its closed position, so that any water collected at the second seal is drained through the second receptacle, e.g. into a drainage channel.

[0028] Accordingly, it may also be provided that the sealing system includes a drainage channel for removing water from the sealing system.

[0029] A drainage channel can, for example, include a borehole in the first base body and / or the second base body, or a special geometry of the first base body and / or the second base body that drains away drainage water by means of a gradient.

[0030] It may also be provided that a first insertion element is rotatably connected to the first base body along a longitudinal axis of the first base body, and a second insertion element is rotatably connected to the second base body along a longitudinal axis of the second base body.

[0031] An insertion element, such as a wing made of metal or another solid material, enables the presented sealing system to be easily and quickly clamped in a given installation situation, e.g. in old buildings, by bridging a gap between the sealing system and the old building and compensating for any height difference.

[0032] It may be provided that the first insertion element and / or the second insertion element forms a flat stepping surface.

[0033] A level step surface is particularly suitable for installation situations where there is no height difference to compensate for, thus creating a level and barrier-free transition area.

[0034] Alternatively, it can be provided that the first insertion element and / or the second insertion element forms a tread surface that is at least partially rounded.

[0035] Rounded insert elements are particularly advantageous for compensating for differences in height, as they distribute the height difference evenly over a radius and thus prevent a step-like elevation.

[0036] It may also be provided that the sealing system includes a number of profiles that overlap a gap between the first base body and the second base body and form a flat surface with both the first base body and the second base body.

[0037] Profiles or inserts that overlap the gap between the first and second base bodies can be used, for example, to adjust the distance between them. A profile can include coupling elements, such as locking lugs, that engage in coupling interfaces or receptacles of the first and second base bodies. For example, a profile can be detachably connected to the first and second base bodies to allow for maintenance of the sealing system.

[0038] According to a second aspect, the presented invention relates to a door system for a pivot door, wherein the door system comprises a lower sealing system and / or an upper sealing system, wherein the lower sealing system and / or the upper sealing system is / are designed according to the presented sealing system.

[0039] While a door threshold or lower sealing system is usually positioned at a floor and forms a lower termination of the door system, a door cover or upper sealing system is usually designed as the upper termination of a door frame.

[0040] Accordingly, the door system may include a door frame that incorporates the lower sealing system and / or the upper sealing system.

[0041] It may also be provided that the door system includes a pivot door, wherein the pivot door includes a magnetic strip that is movably secured in the pivot door.

[0042] A movable magnetic strip, in particular arranged on an upper edge of a pivot door, can interact as a first seal or as part of the first seal with a first base body of an upper sealing system of the presented door system in order to protect a pivot bearing of the sealing system against environmental influences.

[0043] Furthermore, it may be provided that the second seal of a respective sealing system is located at the pivot door.

[0044] A second seal, e.g. in the form of a sealing lip, which is arranged on the pivot door, can interact with a second base body of a respective sealing system of the presented door system in order to protect a pivot bearing of the sealing system against environmental influences.

[0045] It may also be provided that the pivot door weighs more than 200 kilograms, in particular more than 500, preferably more than 1000 kilograms.

[0046] Due to the pivot bearing provided according to the invention, the presented door system can include particularly heavy pivot doors that would be too heavy for wall-mounted brackets.

[0047] Further features, details and advantages of the invention will become apparent from the wording of the claims and from the following description of exemplary embodiments with reference to the drawings. The drawings show: Fig. 1 a possible embodiment of the door system presented, Fig. 2 a further view of the door system presented, Fig. 3 a cutaway view through a further possible embodiment of the door system presented.

[0048] In Fig. 1 A lower sealing system 100 of a door system 200 is shown. The door system 200 also includes a pivot door 201.

[0049] The sealing system 100 comprises a first base body 101, a second base body 103, a rotary bearing (not shown here), a separating element 105, a first seal 107 and a second seal 109.

[0050] The separating element 105 is arranged between the first base body 101 and the second base body 103 and thermally separates them from each other.

[0051] The first seal 107 includes a magnetic strip 113, which is movably arranged in a receptacle 111, so that it lifts up in the receptacle 111 when a counter-magnetic strip 139 of the pivot door 201 is located above it.

[0052] The pivot door 201 also carries a second seal 109 in the form of an elastic sealing lip, which moves with the pivot door 201. Accordingly, the first seal 107 and the second seal 109 surround a gap 115, in which a profile 137 is shown. The pivot bearing of the sealing system 100 can also be arranged in the gap 115.

[0053] The profile 137 connects the first base body 101 with the second base body 103 to form a flat surface, so that the sealing system 100 forms a barrier-free surface when the pivot door 201 is open and the magnetic strip 113 is in the receptacle 111.

[0054] Insertion elements 119 and 121 are rotatably arranged on the first base body 101 and the second base body 103 respectively, through which the sealing system 100 can be easily and quickly inserted into a given installation space.

[0055] The insertion elements 119 and 121 are movably mounted on axes 123 and 125 of the first base body 101 and second base body 103 respectively and are mechanically coupled to them accordingly.

[0056] The first basic body 101 includes a drainage channel 127 for draining water, which is introduced into the sealing system 100, for example, through the pivot door 201.

[0057] In Fig. 2 A rotary bearing 117 of the sealing system 100 is clearly visible. The rotary bearing is arranged in the space 115 and is accordingly protected against environmental influences by the first seal 107 and the second seal 109.

[0058] Fig. 3 Figure 1 shows an upper sealing system 110 of the door system 200, which is arranged above the pivot door 201. The sealing system 110 comprises a magnetic strip 129 and a sealing lip 131, which are integrated into the pivot door 201.

[0059] The sealing system 110, analogous to the lower sealing system 100, comprises a first base body 101 and a second base body 103, as well as a pivot bearing 133 into which a counter bearing 135 of the pivot door 201 engages. Accordingly, the pivot door 201 is rotatably mounted by the two pivot bearings 117 and 133 of the sealing systems 100 and 110 and is fixed in a mounting space.

[0060] The magnetic strip 129 is attracted by a counter-magnetic strip 139 arranged on the first base body 101 of the sealing system 110. The magnetic strip 129, together with the counter-magnetic strip 139, forms the first seal 107 of the sealing system 110, so that the rotary bearing 133 is protected from environmental influences by the first seal 107 and the sealing lip 131, which forms the second seal 109 of the sealing system 110.

[0061] The invention is not limited to one of the embodiments described above, but can be modified in many ways.

[0062] All features and advantages arising from the claims, the description and the drawing, including design details, spatial arrangements and process steps, can be essential to the invention both individually and in various combinations. Reference symbol list
