EP3388608B1 - Sliding element with sealing device and sealing element - Google Patents

Description

The invention relates to a sliding element that can be displaced along a running rail, in particular a sliding door, with a sealing device by means of which a room opening can be closed off. Furthermore, the invention relates to a sealing element for such a sealing device.

To separate rooms or to close off room or window openings, sliding elements such as sliding doors made of glass or wood are often used, which are usually guided along a running rail by means of two running gears. From the US9290977B2 a device with carriages that can be displaced along running rails is known, by means of which a sliding element or a sliding door can be displaced in front of a room opening and finally against the room opening in order to seal it tightly. A seal is provided between the sliding door and the edge of the room opening, a door frame or a frame, which is compressed to a desired extent as soon as the sliding door is guided against the room opening. So that the seal does not appear visually, it is not provided on the front side of the frame, but on the back of the sliding door.

The one in the US9290977B2 disclosed sealing device, hereinafter in 2 is shown, includes a multi-part assembly strip 6, with which a peripheral sealing element 5 is connected. Different elements of the mounting strip 6, straight elements and corner elements, are connected to the rear of the sliding door in such a way that a peripheral frame is formed which runs close to the edge of the rear of the sliding element. The mounting strip 6 or its elements are provided with an anchor channel 60 in which an anchor part 51 of the sealing element 5 can be anchored in order to to fasten the sealing element 5. The anchor part 51 is provided with a compression element 52 which has two chambers 521,522. The first chamber 521 faces outward laterally and the second chamber 522 faces downward. When contacting the edge of the space opening, the first chamber 521 is compressed. As the sliding door is lowered, the second chamber 522 is guided and compressed against the floor.

For the assembly of the sealing device, a relatively large amount of effort is therefore required, since the mounting strip 6 must first be screwed to the sliding element in a precisely aligned manner and only then can the sealing element 5 be inserted. The sealing element 5 has relatively large dimensions. The cost of materials and installation costs is therefore considerable. The combination of the mounting strip 6 and the damping element 5 also requires a lot of space, which is why the sliding element 1' cannot be guided as close to the room opening as would be desirable. The sliding element 1' moved in front of the room opening therefore has an optically voluminous effect. Despite the relatively large dimensions of the sealing element 5, however, this only has relatively small compression paths, which is why correspondingly small and precise deflections of the sliding door or larger dimensions of the damping element 52 are to be provided.

the US2012260579A1 discloses a seal having a T-shaped anchor and a compression body having a circular cross-section and two chambers. The T-shaped anchor requires a T-shaped anchor slot in the door panel, into which the anchor can only be inserted after significant deformation. The armature is therefore hardly seated without play and is exposed to considerable loads. The compression body with the circular cross-section has only has a relatively small compression path and can therefore only seal small air gaps.

the DE4228986A1 discloses a glazing seal for a door or window having an arrow-shaped anchor member which engages a forwardly opening T-shaped anchor groove formed to match. In this configuration, the seal cannot be advantageously anchored, particularly at the edge of the door.

the EP1431501A2 discloses a sliding door system with a sliding leaf guided so as to be horizontally displaceable in a guide device and a sealing device with sealing profiles rest directly on a floor covering or directly on one another, which is why disruptive friction results, which is reduced by appropriate choice of material.

The present invention is therefore based on the object of creating an improved sliding element with a sealing device and an improved sealing element.

The sealing device should have a simple structure and be able to be installed with little effort. The sealing device should require as little material as possible and be able to be implemented inexpensively. The sealing device should also make it possible to move the sliding element or the sliding door close to the room opening or to a door frame or frame provided there. The sliding element with the sealing device should be able to be realized with slim dimensions, resulting in an aesthetically advantageous impression. The sealing element should be easy to assemble and, despite relatively small dimensions, have a relatively large compression path and seal the gap between the sliding element and the frame tightly.

This problem is solved with a sliding element with a sealing device according to claim 1. Preferred configurations of the invention are defined in further claims.

The sliding element comprises a sliding plate with a sealing device with at least one sealing element forming a sealing frame which is arranged at the rear of the sliding plate and runs peripherally along an edge of the sliding plate. The dimensions of the sealing frame correspond approximately to the dimensions of the edge of a room opening or the dimensions of a frame that is provided on the room opening that is to be closed off by the sliding element or the sliding door.

According to the invention, the sliding plate has a base plate and a flange plate offset from it, which is connected in one piece to the base plate and the edge of which is separated from the base plate by a circumferential anchor groove, which serves to hold the at least one sealing element, which has an anchor part that can be inserted into the anchor groove and has a compression part, which are connected to one another by a connecting body, wherein the anchor part of the at least one sealing element is aligned at least approximately parallel to the sliding plate within the anchor groove.

With the solution according to the invention, the use of a mounting strip provided with an anchor groove can be dispensed with. The anchor groove is advantageously worked into the sliding plate, with the base plate visible from the front side of the room opening on the one hand and the flange plate visible from the rear side of the room opening enclosing the anchor groove on the other hand. The base plate and the flange plate face in opposite directions pointing outer surfaces, which are preferably designed identically and are not distinguishable for the user. The dimensions of the base plate are preferably slightly larger at the side and top than the dimensions of the flange plate, so that a receiving space is provided for the connecting body of the associated sealing element, which is supported on the base plate set back from the flange plate. The associated sealing element is therefore not only anchored in the sliding plate, but is also partially accommodated by it, which is why only the device parts that are relevant to the sealing function protrude from the sliding plate. On the other hand, on the underside, the flange plate can protrude beyond the base plate and can be used to cover the sealing element provided there.

The at least one sealing element can thus be installed quickly and easily in the anchor groove and optimally fulfills the sealing function while it is not visually apparent. Due to the omission of a mounting strip, the sliding plate with the sealing device integrated therein can be designed to be slim and aesthetically advantageous. The room opening can be tightly sealed by means of the sliding element according to the invention or the sliding door according to the invention. Due to the lack of a mounting strip and the integration of the sealing elements in the sliding panel, the slim sliding panel can be moved close to the room opening and takes up very little space in front of the tightly sealed room opening.

Since the sliding plate with the anchor groove is machined and the sealing element can also be quickly inserted into the anchor groove at the installation site, this can be done sliding element according to the invention can be manufactured inexpensively with a minimum of work and material costs.

The sealing elements or sealing profiles can be made of conventional materials such as rubber or silicone. Different materials can also be used for the anchor part on the one hand and for the compression part on the other hand, the properties of which are adapted to the respective function of the anchor part or the compression part. For example, the anchor part can be made of a less elastic material than the compression part.

In a preferred embodiment, a first sealing member is provided in an upper part of the anchor groove at the top of the slide plate and in left and right parts of the anchor groove at the left and right sides of the slide plate, and in a lower part of the anchor groove at the bottom of the slide plate a second sealing element anchored with its anchor part. With two different sealing elements, the assigned tasks can be optimally fulfilled with minimal material expenditure. The first sealing element results in a lateral coupling to a plane that is defined by the edge of the room opening or a frame mounted there. This means that the sliding plate can be pushed in front of the room opening and driven against it, with the room opening being tightly sealed at the side and at the top by means of the first sealing element. The second sealing element serves to close off a gap which remains between the sliding plate and the floor after the sliding plate has been lowered.

A stable connection between the sliding plate and the first sealing element and at the same time a space-saving partial integration of the first sealing element in the Sliding plate is achieved in that the anchor part of the first sealing element is kept aligned at least approximately parallel to the sliding plate within the anchor groove. On the other hand, optimal sealing results when the compression part of the first sealing element is aligned with a first compression axis perpendicular to the slide plate.

A particularly reliable seal is achieved in that the compression part of the first sealing element is designed at least approximately symmetrically and forms a cardioid with two contact zones and an axis of symmetry that corresponds to the first compression axis. With the configuration at least approximately in the form of a cardioid, two contact zones result after the sliding door is closed, which practically bring about a double seal.

As mentioned, the first sealing element can also be used exclusively to form the sealing frame. That is, the first sealing member can also be provided on the underside of the slide plate.

In a preferred embodiment, a second sealing element is provided, the anchor part of which is aligned at least approximately parallel to the slide plate within the anchor groove and the compression part of which has a second compression axis that runs parallel to the slide plate. The circumferential armature slot is therefore also aligned parallel to the base plate and flange plate.

The second sealing element can be made particularly slim by providing that the second compression axis, which is vertically aligned after the assembly of the second sealing element, passes through the anchor part and the compression part of the second sealing element.

It is preferably provided that the compression part of the second sealing element has a bending fold on at least one side or at least one bending fold on both sides, which is or are aligned transversely, preferably perpendicularly, to the second compression axis. If several bending folds are provided, they are arranged alternately on both sides of the compression part and offset from one another along the second compression axis.

The bending folds are designed and arranged such that when the second sealing element is displaced along the second compression axis, the compression part of the second sealing element is compressed, with the compression chambers being displaced essentially along the second compression axis and not being deflected laterally. The design of the second sealing element according to the invention therefore provides that its compression part is compressed along the second compression axis. After the sliding door is closed, a wide sealing body results on its underside, which tightly closes the associated door gap. Folding away of the compression part to the side, which would prevent the desired compression, is avoided. Due to the compression of the compression part along the second compression axis, a relatively wide door gap can be reliably sealed without a sealing element having larger dimensions being required. The second sealing element can therefore be made very slim and still optimally fulfill the sealing function.

In preferred configurations, the compression part of the second sealing element has at least two compression chambers, which are one above the other along the second compression axis lying and which move essentially along the second compression axis when the second sealing element is lowered against the ground. The compression chambers, which have cavities, ensure perfect acoustic and thermal sealing.

The bending fold or one of the bending folds is preferably provided along the second compression axis between the compression chambers. Bending folds can also be provided on the walls of the compression chambers in order to facilitate the compression process, optionally in combination with a folding process. The at least one bending fold can be in the form of a curve, groove or material recess.

The sealing frame can also be formed entirely by the second sealing element. This means that the second sealing element can also be inserted into the anchor groove at the side and at the top of the sliding plate.

The first sealing element or the second sealing element or combinations of the first and second sealing elements can therefore be advantageously used to form the sealing frame. In all possible alternative configurations, it is preferably always provided that the compression axis of the compression part is aligned perpendicularly to the body or to the body surface that is to be sealed. The compression parts of the first sealing element and the second sealing element can be aligned with their compression axis parallel or inclined, preferably perpendicular to the axis of the anchor part of the relevant sealing element. The first and second sealing elements can therefore be universally used individually or in combination and in various configurations to form a sealing frame.

Fig. 1a shows a sliding system 100 according to the invention with a sliding element according to the invention or a sliding door 1, which in this preferred embodiment can be displaced along two running rails 9 in front of a room opening or a frame 8. The rails 9 are covered by a screen 99. Alternatively, just one track can be used.

In preferred configurations, the sliding system 100 is designed in such a way that the sliding door 1 can be slid horizontally in front of the room opening and in the final phase of the closing process against the frame 8 and against the floor in order to tightly seal the room opening on all sides.

For this purpose, the sliding door 1 comprises a sliding panel 10 made of wood, for example, which in this preferred embodiment is provided with a sealing device which has a first sealing element 2, which runs at the top and along the lateral edges of the sliding panel 10, and a second sealing element 3, which runs on the underside of the sliding plate 10. The two sealing elements 2, 3 thus form a sealing frame on the rear side of the sliding door, which is partially or preferably completely self-contained. When the sliding door 1 is closed, the first sealing element 2 is guided and compressed against the frame 8 and the second sealing element 3 against the floor, resulting in an optimal acoustic and thermal seal.

The sliding plate 10 has a base plate 11 at the front and a flange plate 12 facing the frame 8 at the rear. Between the base plate 11 and the flange plate 12 there is an anchor groove 18 running around the flange plate 12 in the shape of a frame provided, in which the sealing frame with the first and second sealing element 2, 3 was used.

The sliding plate 10 is optionally provided with an edge piece 15 on the left edge outside of the sealing element 2 , which is connected to a first running gear 91 . The front of the sliding plate 10 is connected to a second drive 91'. The two drives 91, 91' are preferably guided on different rails 9, 9', as is shown in FIG US9290977B2 is described. The front second carriage 91' can be moved completely away from the room opening via the second running rail 9'. So that the first carriage 91 does not get into the area of the second running rail 9', it is shifted relative to the area of the sliding door 1, which is provided with the sealing device for sealing the room opening. In the present embodiment, this is particularly advantageous due to the asymmetrical design of the sliding door 1 with the additional edge piece 15. The carriages 91, 91' could thus advantageously be decoupled from the adjacent running rails 9', 9 and the room opening can be opened completely.

The edge piece 15 shown hatched is therefore only optionally provided and can also be omitted. Without this edge piece 15, the left side of the rail plate 10 would be configured identically to the right side and in the same way with the elements of the sealing frame 2; 3 provided. The sliding element 1 can therefore be designed symmetrically or asymmetrically.

Fig. 1b (see also Figure 3a ) shows that the sliding door 1 is very slim even with the sealing device installed. Essentially only the parts of the sealing elements 2, 3 required for sealing are visible. The other parts of the sealing elements 2, 3 are integrated into the sliding door 1.

2 shows the one from the US9290977B2 known sliding door 1', which is provided with a sealing device comprising mounting strips 6 screwed to the sliding door 1' and a peripheral sealing element 5. The sealing element 5 has an anchor part 51 and a compression part 52 which comprises two compression chambers 521,522. The anchor part 51 is held in an anchor channel 60 of the mounting strip 6 .

Figure 3a shows the upper left corner of the asymmetrically designed sliding panel 10 of FIG Fig. 1b , which has the extended edge piece 15 to the left of the first sealing element 2 , which is connected to the first drive 91 via a connecting device 92 . For this purpose, a mounting device 93 is inserted into a mounting channel 19 which is worked into the upper side of the sliding panel 10 .

The sealing element 2 shown forms part of the Fig. 1b shown sealing frame, which is provided on the back of the sliding plate 10. The sealing frame includes, as in Fig. 1b and Figure 4b shown, the first sealing element 2, which forms the upper part and the lateral parts of the sealing frame, and the second sealing element 3, which forms the lower part of the sealing frame. The shape of the sealing frame is preferably adapted to the shape of the sliding panel 10 and/or the shape of the edge of the room opening or the frame 8 provided there.

Figure 4b also shows that the first and the second sealing element 2, 3 each have an anchor part 21; 31 and a compression part 22; 32 formed by a connecting body 20; 30 are connected to each other.

This in Figure 3a The first sealing element 2 shown is almost completely integrated into the sliding door 1. The armature part 21 is accommodated in an armature slot 18 . The connecting body 20 is received in a receiving space 14 adjoining the anchor slot 18 . The compression part 22, however, protrudes from the receiving space 14, preferably at least to the extent that it is to be compressed to achieve a tight seal. Out of Figure 3a it can therefore be seen that the sliding door 1 can be manufactured with minimal dimensions and the sealing device is integrated into the sliding panel 10 in an aesthetically advantageous manner.

So that the sealing frame with the sealing elements 2 , 3 can be installed in such an advantageous manner, a circumferential anchor groove 18 is let into the back of the sliding plate 10 . The anchor groove 18 forms an anchor frame which corresponds to the sealing frame with the sealing elements 2, 3. The sliding plate 10 comprises a base plate 11 on the front and a flange plate 12 on the rear facing the room opening, which is connected in one piece to the base plate 11 and is separated from the base plate 11 peripherally only by the anchor groove 18 and the receiving space 14 . By incorporating the receiving space 14 and the anchor groove 18, the flange plate 12 is exposed at its edges. For example, in a first step, the receiving space 14 and in a second step the anchor groove 18 is exposed, which is aligned between the base plate 11 and the flange plate 12 parallel thereto against the adjacent side of the sliding door 1. The profile of the incorporated recess with the receiving space 14 and the anchor groove 18 is therefore preferably an L-profile directed towards the center of the flange plate 12 . Since the sliding plate 10 is preferably made in one piece with the base plate 11 and the flange plate 12, the front side and the rear side of the sliding door 1 have an identical appearance unless the user desires a different configuration. After the sliding door 1 has been closed, the sealing frame 2, 3 rests against the frame 8 and the floor, which is why it is not visible. For example, only a white surface or the wooden structure of the sliding panel 10 made of wood is visible on the front and rear.

The sliding plate 10 can also be made of metal or plastic. If the sliding plate 10 is made of plastic, for example in a mold, the interior corresponds to the dimensions of the slide plate, filling material with an L-profile is arranged at the position where the receiving space 14 and the anchor groove 18 are to be provided. The plastic is then poured into the mold.

Since at least part of the sealing frame 2, 3 is to be accommodated in the receiving space 14, the dimensions of the flange plate 12, corresponding to the dimensions of the sealing frame 2, 3, will be smaller than the dimensions of the base plate 11.

Figure 3b shows the upper left corner of the asymmetrically designed sliding panel 10 of FIG Figure 3a before inserting the sealing frame or the first sealing element 2. It is shown that the flange plate 12 is peripherally separated from the base plate 11 by the receiving space 14 running in the shape of a frame and the anchor groove 18 running in the shape of a frame. The flange plate 12 is therefore lifted off the base plate 11 on the rear side of the sliding plate 10 . Preferably, the flange plate 12 and the side piece 15 of the sliding plate 10 form a flat surface. Figure 3b thus shows that not only on the mounting bar 6 of the known solution 2 could be dispensed with in order to save material, work and space, but that parts of the sealing frame 2, 3 that are not required for the sealing function can be sunk into the sliding plate 10 in order to save space.

Figure 4a above shows that along section line A--A of Fig. 1b cut out upper right corner piece of the sliding plate 10 and below along the cutting line B - B of Fig. 1b cut-out lower right-hand end piece of the sliding plate 10. The cut-out intermediate piece between the two end pieces and the left-hand part of the sliding plate 10, which can be configured symmetrically or asymmetrically, are symbolized by auxiliary lines. It can be seen that the flange plate 12 is peripherally separated from the base plate 11 by the anchor groove 18, but is also connected to it in one piece. The anchor slot 18 has an upper anchor slot part 181 at the top, a lower anchor slot part 183 on the underside and lateral anchor groove parts 182 on the right and left sides of the flange plate 18. The armature groove 18 with the armature groove parts 181, 182, 183 is thus designed in the shape of a frame and allows the accommodation of the preferably completely self-contained sealing frame 2, 3, which is rectangular in the embodiment shown, but can also have curves or arcs.

Figure 4b shows the corner pieces of the right edge of the sliding panel 10 of FIG Figure 4a with the sealing frame inserted into the armature groove 18, which in this preferred embodiment comprises a first sealing element 2 and a second sealing element 3, which are designed differently and fulfill different functions. The first sealing element 2 is inserted in the upper anchor groove part 181 and in the lateral anchor groove parts 182 and serves to seal the sliding plate 10 against the frame 8 (see FIG Fig. 1a ). The second sealing element 3 is inserted into the lower anchor groove part 183 and serves to seal the lowered slide plate 10 against the ground.

Like this in the figures 4b , 5 , 6a, 6b and 6c is shown, the two sealing elements 2, 3 each have an anchor part 21 that can be inserted into the anchor groove 18; 31 and a compression part 22; 32, which is formed by a connecting body 20; 30 are connected to each other.

Figure 5a shows that the anchor part 21 of the first sealing element 2, which has the profile of a fir tree, is held within the anchor groove 18 and is aligned at least approximately parallel to the sliding plate 10 and that the compression part 22 of the first sealing element 2 has a first compression axis x, which is perpendicular to the Sliding plate 10 is aligned. The anchor part 21 is therefore securely held in the anchor groove 18 while the connecting body 20 is accommodated in the accommodation space 14 and supported on a part of the base plate 11 .

Following the anchor groove 18, the connecting body 20 of the sealing element 2 is supported on the flange plate 12 with a shoulder piece 201, as a result of which a uniform alignment of the first sealing element 2 is ensured.

The compression part 22 of the first sealing element 2 is at least approximately symmetrical and forms at least approximately the shape of a cardioid with two contact zones 221, 222 and an axis of symmetry which corresponds to the compression axis x, which is aligned perpendicularly to the spatial opening. When the sliding door 1 is closed, the two contact zones 221, 222 meet the frame 8, after which the compression part 22 is pressed against the base plate 11 and deformed while maintaining the symmetry. The two contact zones 221, 222 bring about a double seal, which is why reliable thermal and acoustic insulation results.

Figure 4b shows that the anchor part 31 of the second sealing element 3, which also has the profile of a fir tree and largely corresponds to the anchor part 21 of the first sealing element 2, is held within the anchor groove 18 and is aligned at least approximately parallel to the sliding plate 10 and that the compression part 32 of the second Sealing element 3 has a second compression axis y, which is oriented at least approximately parallel to the slide plate 10 and, after installation, perpendicular to the ground.

In this preferred embodiment, the compression axis y runs through the anchor part 31 and the compression part 32 of the second sealing element 3 approximately in the middle. In this way, only a small amount of space is required for installing the second sealing element 3 . The connecting body 30 of the second sealing element 2 is supported with a shoulder piece 301 on a shortened part 111 of the base plate 11, which ensures that the assembled second sealing element 3 is aligned along a straight line. The flange plate 12 protrudes downwards beyond the shortened part 111 of the base plate 11 and serves as a screen to cover the connecting body 30.

It has already been stated that the sealing frame can consist of the first sealing element 2, the second sealing element 3 or a combination thereof. If the sealing frame consists only of the first sealing element 2, this forms all 4 parts of the sealing frame in the manner shown in Figure 4b is shown above. If, on the other hand, the sealing frame consists only of the second sealing element 3, this can, as in Figure 5b , shown, can be inserted into the anchor groove 18 from all sides.

Figure 5b shows an example of the lower right corner piece of the sliding plate 10 in a preferred embodiment with the second sealing element 3, which forms all four parts of the sealing frame in this embodiment. The longitudinal axis a of the anchor part 31 and the second compression axis y are aligned coaxially with one another.

Figure 6a shows a spatial representation of a section of the unloaded second sealing element 3 with the anchor part 31 and the compression part 32 which are connected to one another by the connecting body 30 . The anchor part 31 adjoining the connecting body 30 at the top, which is aligned along the compression axis y, shows the profile of a fir tree and is provided with two pairs of anchor elements 311 . The connecting body 30 is provided with the shoulder 301 serving as a flange member. The compression element 32 has a smaller first compression chamber 321 and a larger second compression chamber 322, which are arranged one above the other along the compression axis Y. A first bending fold 323 is formed in the side walls of the first compression chamber 321 . A second bending fold 324 is formed between the two hollow compression chambers 321, 322. The first and second bending folds 323, 324, respectively Indentations are directed towards each other and are formed at least approximately symmetrically to the compression axis y.

The bending folds 323, 324 and the compression chambers 321, 322 are designed in such a way that when the second sealing element 3 is displaced along the second compression axis y or when the sliding plate 10 is lowered vertically, the compression part 32 of the second sealing element 3 is compressed and possibly partially folded. The compression chambers 321, 322 are shifted downward essentially along the second compression axis y. A lateral displacement of the compression element 22, in which the compression or the compression of the compression part 22 is omitted, is avoided. Instead, the compression chambers 321, 322 are compressed along the compression axis y, resulting in a tight seal below the slide plate 10.

Figure 6b shows the unloaded second sealing element 3 of FIG Figure 6a seen from the front.

Figure 6c shows the loaded second sealing element 3 of FIG Figure 6b with the anchor part 31 displaced downwards and the compression part 32 compressed along the compression axis y.

Figure 7a shows the first sealing element 2 with the longitudinal axis a of the anchor part 21 and the compression axis x of the compression part 22 aligned coaxially with one another. Instead of the second sealing element 3, therefore, the first sealing element 2 in the same way in the anchor groove 18, for example, on the underside of the rail plate 10 of Figure 4b be used. The shoulder piece 201 drawn with a dot-and-dash line is provided as needed.

Figure 7b shows the second sealing element 3 with the longitudinal axis a of the anchor part 31 and the compression axis y des Compression part 32 aligned perpendicular to each other. Instead of the first sealing element 2, therefore, the second sealing element 3 in the same way in the anchor groove 18, for example, on the top of the rail plate 10 of Figure 4b be used. The shoulder piece 301 drawn with a chain line is provided as needed.
