ARRANGEMENT WITH A BOTTOM SEAL FOR A DOOR, IN WHICH A SPACE IS PROVIDED BETWEEN A DOOR LEAF AND A FRAME, IN WHICH A RADIAL AXIS OF THE DOOR LEAF RUNS.

Description

[0001] The present invention relates to an arrangement with a door in which a space is provided between a door leaf and a frame in which a single axis of rotation of the door leaf runs, and with an automatic seal comprising a housing, a movable sealing profile, a mechanism for moving the sealing profile relative to the housing, and a pressable trigger for actuating the mechanism, which, in the untriggered state of the seal, projects beyond the housing on one hinge side.

[0002] Revolving doors and various types of swing doors, pivot doors or pivot doors are known from the state of the art.

[0003] Hinged doors are the most common type of door. They are mounted on hinges in a frame, allowing them to pivot, and rest against the frame when closed. A hinged door whose only axis of rotation lies in a space between the frame and the door leaf is known from document GB 2 201 712 A.

[0004] The aforementioned installation situation with a gap between the door leaf and the jamb board of the frame can occur with hinged doors, particularly with hinged doors that are equipped with finger guards to prevent reaching into the gap between the frame and the door leaf when the door is open. Such finger guards are disclosed, for example, in application DE 10 2019 119 299.4. The gap between the door leaf and the jamb board on the hinge side of the door is filled by parts of the hinges and profiles that serve as finger guards.

[0005] Swing doors, pivot doors or swing doors can be distinguished, among other things, by how the door leaf of these doors swings.

[0006] Firstly, there are pivot doors, whose door leaves are attached to a jamb board of the frame via hinges, through which the door leaf can be pivoted from a closed position of the door into a first opening direction around a first axis of rotation, and through which the door leaf can be pivoted from the closed position into a second opening direction opposite to the first opening direction around a second axis of rotation.

[0007] Secondly, there are pivot doors, whose door leaves are attached to the floor and a lintel of the frame or ceiling via hinges. The pivot axis of the door leaf runs through the door leaf between the hinges.

[0008] Thirdly, there are pivot doors, which are attached to a jamb board of the frame via hinges, but where the door leaf can only be pivoted around a single axis in both opening directions. As described earlier, this single axis of rotation runs through a gap between the door leaf and the jamb board of the frame. This gap is usually sealed to prevent drafts and sound transmission between the two rooms separated by the door. Plastic and / or aluminum profiles can be used for this purpose.

[0009] In many applications of hinged or pivot doors, there is a need to seal a gap between the door leaf and the floor when the door is closed.

[0010] For sealing these gaps, especially in hinged doors, so-called automatic seals have proven effective for various reasons. With these seals, a sealing profile, movably attached to the door leaf, is automatically lowered to the floor when the door is closed. This lowering movement is achieved via a mechanism connected to both the sealing profile and the door leaf. As the door leaf moves into its closed position, a force is applied to this mechanism, activating it. This force is applied via a trigger mechanism that protrudes beyond the door leaf on the hinge side. This trigger is slidably mounted and strikes the jamb of the frame when the door closes. This action transmits the force necessary to move the sealing profile into the mechanism.When the door is opened, if the release mechanism is disengaged from the jamb board of the frame, the sealing strip is lifted by the force of springs that were tensioned during the lowering movement. An automatic seal is known, for example, from document DE 20 2017 107 248 U1.

[0011] Most automatic door seals have a housing that is attached to the door leaf and contains the mechanism. When not activated, the sealing profile is also usually largely enclosed within the housing.

[0012] The housing of hinged doors has a width that corresponds to the width of the door leaf to which it is attached. The sealing profile usually protrudes slightly laterally beyond the housing, allowing its ends to rest against the frame when the door is closed. However, if a gap is provided between the door leaf and the frame on the hinge side, as described earlier, the sealing profile cannot rest against the frame on the hinge side. Consequently, the sealing profile cannot provide a seal between the door leaf, the floor, and the frame when the door is closed.

[0013] This is where the present invention comes in.

[0014] The housings of automatic door seals are usually attached using brackets that are inserted laterally into the housing and screwed to the door leaf. This type of attachment has proven particularly effective because the seal can be attached and detached even with the door already installed.

[0015] An automatic door seal is typically triggered by a release mechanism protruding from the hinge side of the door. For doors with the gap described earlier, triggering with a hinge-side release mechanism requires the release to protrude significantly from the seal due to the space between the door leaf and the hinge-side jamb of the frame. This is also not a practical solution, particularly since the kinematic conditions for force transmission to the release mechanism are unfavorable.

[0016] This is also where the present invention comes into play.

[0017] The present invention is based on the objective of proposing an arrangement consisting of a door in which a gap is provided between a door leaf and a frame, in which a single axis of rotation of the door leaf runs, and an automatic seal in which, despite the gap, a sealing of the space between the door leaf, floor and frame is possible.

[0018] This problem is solved according to the invention by the fact that the housing, the trigger and the sealing profile of the automatic seal project beyond the door leaf on the hinge side and project into the space between the door leaf and the frame.

[0019] By extending the sealing housing, the trigger and the sealing profile, a prerequisite is created for sealing the lower, floor-side end of the gap between the door leaf and the frame in various ways.

[0020] It is possible that the trigger protrudes so far beyond the door leaf that it strikes the frame when the door closes and remains in contact with the frame when the door is closed. Even when the door is closed, the trigger of the automatic seal maintains a distance from the frame in the triggered state. In this case, the trigger cannot strike the frame when the door closes to activate the seal. This problem is remedied in a seal according to the invention by a stop attached to the frame and positioned between the frame and the seal's trigger, whereby the trigger rests against the stop, at least when the seal is triggered. The attachment can be direct or indirect to the frame. For example, the stop can be connected to the frame via a part of one of the door hinges that is attached to the frame.

[0021] A stop suitable for the seal according to the invention can have a first curve. In this case, a first scanning surface of the trigger can rest against the first curve. The stop and the trigger can thus form a first cam mechanism. As the door leaf rotates relative to the door, the trigger also rotates relative to the stop. The scanning surface of the trigger can then slide over the first curve of the stop. The trigger thus follows the first curve. The first curve can be designed such that the trigger is depressed when the door is closed, thereby triggering the seal, or is depressed when the door is closed, thereby triggering the seal.

[0022] The first curve can be designed so that the movement of the trigger, even when the door swings uniformly, is accelerated, decelerated, or remains constant depending on the shape of the first curve. The slope of the curve can be varied to achieve this.

[0023] The stop can be formed by a pin. This pin can be attached directly or indirectly, for example, by means of one or more connecting pieces to a part of a hinge attached to the frame. The connection between a connecting piece and the hinge part, between two connecting pieces, between a pin and a connecting piece, or between a pin and the hinge part can be adjustable, such that the angle between the two connected parts can be set by rotating them around a central axis of the first curve. The central axis of the curve preferably coincides with the single axis of rotation of the door leaf. This makes it possible to adjust the angle of the first curve relative to the hinge part on the one hand and to the release mechanism on the other. By changing the angle, earlier or later actuation of the release mechanism can be achieved.

[0024] The pivot can be in two parts. It is possible for the two parts of the pivot to be rotated relative to each other around a central axis of the first curve, which may coincide with the single axis of rotation of the door leaf. This change in angular position can also result in earlier or later activation of the trigger.

[0025] The curve can be provided at a free end of the pin.

[0026] An arrangement according to the invention can include a holder that is attached to the door leaf and to which the hinge-side end of the housing is attached, preferably inserted. The holder can be mounted on the door leaf before or after the door leaf is hung on the frame. The sealing housing can then be inserted into the mounted holder, preferably from the lock side of the door leaf. The holder can have an insertion opening with a contour corresponding to the outer contour of the sealing housing, allowing the housing to be inserted into the holder. To limit the insertion path of the housing and also to ensure the seal is securely attached to the door leaf, the holder can have a stop up to which the housing can be inserted into the holder.

[0027] Furthermore, the holder can have at least one mounting structure with which it can be attached to a door leaf. Mounting structures can be holes for screws. Preferably, the holder is attached to a hinge side of the door leaf, in particular by screwing it in place.

[0028] The holder may have a slot through which the sealing profile can be lowered towards the ground when triggered. Raised ridges may be provided at the edges of the slot, on which the seal housing can rest.

[0029] The holder may have an opening through which the trigger can protrude.

[0030] To bridge a gap between the sealing profile of a triggered seal and the frame, an arrangement according to the invention can include a sealing element. This element is arranged, at least when the door is closed, in an area between the hinge-side end of the sealing profile, the floor, and the frame, and seals this area.

[0031] The sealing element can be directly or indirectly firmly connected to the sealing profile of the seal, so that it follows the movement of the sealing profile and can be moved into a sealing position when the seal is triggered and into a release position when the trigger is released.

[0032] It is also possible that the sealing element is connected to the holder. The sealing element could be rigidly connected to the holder and permanently in a sealing position. Alternatively, it could be movably connected to the holder. In this case, a mechanism, for example, a second cam drive, could be provided, which allows the sealing element to move from a release position to a sealing position and vice versa. The cam drive can have a second cam on the holder. The sealing element can have a second scanning surface, for example, on a sensor, which can be moved in a direction perpendicular to the seal's trigger point. A linear guide can be provided, by which the sealing element is guided linearly along the holder.This guide can have a first guide element on the holder and a second guide element on the sealing element, which work together to guide the sealing element.

[0033] The holder or stop can be cast parts, especially injection-molded plastic parts. However, it can also be milled parts, particularly made of plastic.

[0034] The sealing element can be a plastic part, in particular a two-component plastic part.

[0035] Further features and advantages of the present invention are explained with reference to the figures. These show: Fig. 1 a perspective view of an arrangement with a door, an automatic seal, a stop, a holder and a sealing element, Fig. 1a a first horizontal section through the arrangement in a first plane, Fig. 1 a detail from the Fig. 1a , with sealing element 11 and stop 9 removed, Fig. 1 shows a second horizontal section through the arrangement in a cutout analogous to Fig. 1b , however, only with the sealing element 11 removed, Fig. 2 shows a section of the view according to Fig. 1 , Fig. 3 the view according to Fig. 2 , however without the door frame, Fig. 4 shows a section of the view according to Fig. 3 , Fig. 5 the section according to Fig. 4 , however without holder, Fig. 6 the section according to Fig. 4 , however without holder and stop, Fig. 7 the section according to Fig. 4, however without holder, stop and seal, Fig. 8 a perspective view of the holder, Fig. 8a a top view of the holder, Fig. 8b a front view of the holder, Fig. 8c a side view of the holder, Fig. 8e a bottom view of the holder. Fig. 9 a perspective view of the stop Fig. 9a a top view of the stop, Fig. 9b a front view of the stop, Fig. 9c a side view of the stop, Fig. 9e a bottom view of the stop.

[0036] The arrangement according to the invention, as shown in the figures, comprises a door T with a frame 1 and a door leaf 2. The frame 2 can be attached in a door opening in a wall in a known manner. The door leaf 2 is pivotally attached to the frame 1 by means of hinges 5. It is a hinged door.

[0037] What is unusual for a hinged door is that the pivot axis of the door leaf runs in a gap between the door leaf and the frame, more precisely between a narrow edge of the door leaf on the hinge side and the frame. The hinges are housed in this gap. The door leaf is preferably unrebated on its narrow edge on the hinge side.

[0038] The gap between the hinge side of the door leaf 2 and the frame 1 allows for visual connection, airflow and sound transmission between the two sides of the door, which is sealed in the case of conventional rebated or flush doors, so that no visual connection is possible and airflow and sound transmission are at least reduced.

[0039] Furthermore, body parts and / or objects can be inserted into the gap, which could potentially be injured or damaged when the door leaf 2 is moved.

[0040] Profiles 3 are provided to close the gap; these are attached to the narrow side of the door leaf 2 on the hinge side.

[0041] A gap exists between the lower edge of the door leaf 2 and the floor (not shown). This gap is sealed by an automatic seal 10 when the door is closed. This automatic seal 10 can be a known seal comprising a housing 101 containing a mechanism for moving a sealing strip from a release position to a sealing position and vice versa. The sealing strip has a sealing profile 102 which rests on the floor in the sealing position. The sealing strip is moved from the release position to the sealing position by pressing a trigger 103. This can tension a spring. The sealing strip can be moved from the sealing position to the release position by releasing the spring when the trigger is depressed.

[0042] The seal 10 is attached in a groove at the lower end of the door leaf 2. For this purpose, a mounting bracket (not shown) is provided on the lock side of the door leaf 2, which holds the lock-side end of the housing 101 of the seal 10. On the lock side, the housing 101 is flush with the door leaf 2, thus enabling attachment to the door leaf 2. The mounting bracket is inserted into the housing 101 on the lock side.

[0043] On the hinge side of the door leaf 2, the seal 10 protrudes into the gap between the door leaf 2 and the frame 1. Therefore, fastening with a mounting bracket that is inserted into the housing from the front is not possible.

[0044] A holder 6 is provided for attaching the hinge-side end of the housing 1 of the seal 10. This holder is attached to the narrow side of the door leaf on the hinge side. The holder 6 has a projecting mounting structure 68 that can be screwed or glued to the door leaf. This holder 6 has a insertion opening into which the hinge-side end of the housing 101 is inserted. The housing 101 rests against a limiting element 62, which limits the insertion path. The position of the hinge-side end of the housing 101 is determined by the limiting element 62, an upper wall 63 of the insertion opening, and a retaining element 111. A sealing profile opening is formed through which the sealing strip or sealing profile 102 can pass between the webs 61. The insertion opening is open on the hinge side, allowing the release 103 of the seal to project into a space adjacent to the insertion opening.In this space, a stop 9, or at least a part of this stop 9, is arranged against which the trigger 103 can strike when the door closes in order to be actuated. This adjacent space has the shape of a circular cylinder and is radially bounded by a wall that is interrupted only by a connection to the insertion opening. This cylindrical space, bounded by the wall 64, is not closed at either the top or the bottom.

[0045] The stop 9 is a pin that is rotatably arranged in the space adjacent to the insertion opening. The pin has a collar 92 that rests on an upper edge of the wall 64. The collar 92 separates an upper end 91 and a lower end 93 of the pin. The lower end of the pin, or stop 9, projects into the space bounded by the wall 64. The upper end projects into one of the profiles 3 between the holder 6 and the lower hinge 5 of the door. The stop 9 is rotatably arranged relative to the profile 3 and the holder.

[0046] This profile 3 is hollow, and a connecting element 4 is guided through the profile 3, creating a rotationally fixed connection between the part of the door hinge 5 attached to the frame 1 and the stop 9. The rotationally fixed connection between the stop 9 and the connecting element is made possible by an internal square drive provided in the upper end 91 of the stop. A complementary structure at the lower end of the connecting element engages in the internal square drive at the upper end of the stop 9.

[0047] At the lower end 93 of the stop 9, a first curve 94 is formed with a varying distance to the axis of rotation of the door leaf 2, which coincides with the central axis of the upper end 91 of the stop 9. A sensing surface 1031 of the release 103 rests against this first curve 94 under preload from a spring in the seal. A rotation of the door leaf 2, and thus of the release 103, relative to the stop 2 causes a displacement of the release 103 relative to the first curve 94. This allows the release 103 to be depressed by the stop 9. The release 103 and the first curve 94 of the stop 9 form a first cam mechanism, which converts the rotation of the door leaf 2 into a horizontal linear movement of the release 103. The mechanism of the seal 10 converts this horizontal linear movement into a vertical linear movement, allowing the sealing strip to move from the release position to the sealing position and vice versa.

[0048] At the lower end of the holder, recesses 65 are provided. These form fastening elements to which the sealing element 11 is attached, which seals the lower, bottom-side end of the gap between the door leaf 2 and the frame 1. The sealing element can be in two parts, comprising a retaining element 111 and a sealing lip 112. However, it is also possible for the retaining element 111 and the sealing lip to be a single piece, manufactured by two-component injection molding or a similar process. Holes 113 are provided in the retaining element 111, through which the sealing element 11 is screwed into the recesses 65 of the holder 6. The retaining element also has a recess through which the directional profile 102 of the automatic seal 10 projects, and on whose edge 1110 the housing 101 of the seal 10 rests.The sealing element adopts the outer shape of the holder 6 at its bottom end and thus has the recess with the edges 1110 through which the sealing strip of the seal 10 can be lowered onto the floor. When the sealing strip is lowered, the sealing profile 102 of the sealing strip rests against the sealing lip 112 of the sealing element from the inside.

[0049] Unlike the sealing profile 12, the sealing element 11 cannot be lowered and remains in constant contact with the floor. Since it is attached to the door leaf 2 via the holder 6, the sealing element 11 rotates with the door leaf 2. As a result, the sealing element 11 rubs against the floor when the door is opened and closed. Because the sealing element 11 is positioned directly on the door's pivot point, the distance it travels along the floor is short, making the rubbing acceptable. However, since this still leads to wear on the sealing element and also requires increased force to move the door leaf, it is advantageous to be able to move the sealing element from a sealing position to a release position and vice versa.

[0050] The arrangement shown features various covers that conceal the profiles 3 and the holder 6, thus giving the arrangement an attractive appearance.
