Abstract

The door panel (10) along its guided edges is provided with plastics slide pieces (20), of which on opening and closing the door panel at least some come into frictional contact with a running rail (96) or the door frame and guide the door panel on these running rails vertically to its plane. The slide pieces have a round, quadratic, rectangular or elliptical shape with at least one slightly convex slide surface. They are of two-part construction for clipping onto the door panel or for snap engagement or screw connection. They locate on the door panel with a sound-absorbing elastic intermediate layer. Their slide surfaces are polished.

Description

Rolling gates leading upwards or to the side are known.

Here the door leaf - also known as the door curtain - consists of pushed together Steel or aluminum profiles (roller shutter profiles). The door leaf is usually in guide rails guided. It can be under the roof of a building, for example a garage. It will Door leaf wrapped on a drum at the lintel of the gate entrance. The rolled-up door leaf armor requires a relatively large amount high lintel from 300 mm to 400 mm.

The same door leaf curtain can also be used in guide rails be pushed to the side. In this case, on the left or right side or the gate entrance behind the Door reveal also a cylinder with approx. 300 mm to 400 mm Diameter.

The profiles of these roller shutter curtains are at least on the inside arched - usually also on the outside. In the rails, which are usually U-shaped Longitudinal slideways may be attached. They usually have Profiles attached to the end faces of plastic gliders rigid, non-adjustable version without noise insulation.

The disadvantage is that these gates are rickety, leaky, very noisy, Space-consuming and without an appealing look are.

It is known for noise reduction of roller shutters (German Utility model 1 924 102), on the inside of the legs a cross-sectionally U-shaped guide rail along the outer edges continuous hollow beads running along the guide rail, preferably made of soft plastic, the for the roller shutter running between them, a two-sided, form flexible support and guidance. This tour too leads to high friction in use.

Ceiling or side doors usually have the same Elements such as roller shutters. The difference is that they not be wound up, but horizontally in running tracks run under the garage ceiling or on rails with rollers run along the side walls of the garage.

In a known such side run or sliding gate can be pivoted together by means of a tension-proof connecting link connected slat members (German utility model G 91 12 024) is behind the lintel and in the floor below a U-shaped support and guide rail open towards the door leaf intended. Roll on the top guide rail several support and guide rollers from the top of stored from the door leaf upwardly projecting flat beams are. From the top and bottom faces of the door leaf there are a larger number of vertical axes with guide rollers from which engage in the U-shaped guide rails and Guide the door leaf across to the door leaf level. This construction is complex.

Another group of overhead or side doors has one made of several profiled sheet metal sheets that cannot be removed Sheet metal tanks. This sheet metal armor is used for transport rolled up into a cylinder. Sheet metal armor of this type slide in horizontal or vertical guide rails. As In the known cases, the sliding element becomes a roller shutter belt used that on the front sides of the sheet metal armor on both Sides of the tank is riveted. With a door width of 2500 mm - 4000 mm deforms depending on the profile of the Sheet metal armor, when steered around the curve, very uneven. The uneven deformation in the past on the Similar products on the market have two causes: The Profiling of the well-known sheet metal armor is such that the surface is largely flat, from lower lying, mostly semicircular beads are removed. This uneven Profiling and the length of the sheet metal form together the cause of the bombing of the wandering around the curve Plate armor.

The disadvantage is that with the slightest damage the whole Tanks must be replaced. The attachment is complicated of four roller shutter belts, two on each long side. The Operation of the gate requires a relatively high Effort. It is an articulated floor and lintel profile required to the door leaf when entering the curve to make turns. The armor of the door leaf is common also profiled like corrugated iron to reduce the friction of the belts to keep low. The assembly of the one-piece tanks is difficult. Large gates cannot be operated reliably realize.

Furthermore, a friction band can be on the outside of the goal armor be attached to the inside of one leg of the U-shaped track come into contact can and leads the goal armor. On the inside of the other A brush band is attached to the leg of the guide rail, that for sealing and also for guidance and noise reduction serves (U.S. Patent 4,234,033). In use can use the friction belt and the brush belt Add dirt, water or ice permanently and increase the Very strong friction.

Both the previously mentioned side or overhead doors Sheet steel (EP-0 367 852 A1) as well as the ceiling and side doors boards usually have on their front edges protruding rolls or rolls for guidance. Depending on whether it is side or overhead doors the arrangement of the rolls or rolls and the diameter different. But it can also occur at larger intervals a steel armored sheet riveted, arched in the direction of movement Sliding elements made of aluminum can be provided (US patent 2,589,938). There is no such execution Noise reduction and does not slide easily. A replacement the slider is difficult. To do this, the door leaf must be removed and the rivets are drilled out.

The overhead and sectional doors include special overhead sectional doors or side run sectional doors. They have Sections of about 400 to 600 mm in height or width with fixed mostly rigid frames that are articulated together are. The sections have a special on the longitudinal edges trained finger protection, hinges and castors. she are the most difficult and the most expensive. Slats can be close be provided with glides in the area of the joint Sliding bends are facing them.

A sectional overhead door for garages with a height of approx. 2000 mm has eight rollers and nine to twelve hinges. A side gate for a garage width of only 2500 mm has approx. 30 to 40 rollers, just like a ceiling door of the same type Size.

The invention is based on the problem of a sectional door, especially with elastic sections, to which the not adhere to the above-mentioned defects, which is smoother easier to move - even after a long time - and that too allows aesthetically satisfactory designs.

According to the invention, this problem is solved by a ceiling or Cross-sectional sectional door with the features of claim 1 solved.

A gate according to the invention can be opened extremely smoothly and close.

The door leaf preferably consists of several transversely elastic ones Sections. This has the advantage that in the manufacture, the Transport and assembly of the gate no bulky pieces available. Because of the light weight and the advantageous The individual sections come with flat bar profiles without cross bracing. Replacing damaged ones Sections are easily possible. The entire door concept is therefore cheaper.

Between the sections there is a complete inside and outside Finger protection without the need for additional elements are. Nor do hinges have to be screwed on or Rubber seals are placed between the sections. Prefers the goal frame is also divided. This allows a section inserted one after the other into the open frame profile and assembled or replaced during repair.

The door leaf of the new ceiling or side door makes a difference in a preferred embodiment of known Door leaves alone because of its cross-elastic Sections and through the transom profile. Inside like from the outside one has the impression that the door leaf is composed of rectangular longitudinal or crossbars. With this sectional door there are partitions between the sections barely noticeable.

For example, there is a door leaf of a sectional overhead door for a garage passage light of 2100 mm in height a preferred embodiment of four to five cross-profiled Sections that are detachably screwed together, the screws are not visible from the outside. The connection the sections can also be screwed through one continuous hinge bead. The sections are then just pushed together.

This sectional overhead door is located in the edge zone of the left and right sections both on the top and on at least one plastic sliding element on the underside of the profiling (Slider) per profile surface. To accommodate the Plastic sliding elements are corresponding in the profile surfaces round or square perforations are provided. Round sliders are clipped into the round openings, in the profiled openings are sliders with accordingly profiled extensions introduced. The sliding piece preferably have an eccentric sliding surface that by turning the sliders a few millimeters to one other slideway can be laid.

The sliders can be one or two parts. For use comes especially a slippery, marketable material. The sliding surfaces are semicircular or lenticular or square and slightly spherical on four sides.

There is between each of the two halves of the sliders an elastic sound-absorbing intermediate layer for sound insulation. The two halves are profiled through a bore Sections stuck and pressed together, interlock with each other through a toothing. Only the sound-absorbing intermediate layer (as well as if necessary an extension of each slide) is in contact with the sheet metal armor of the sections or with a slide holder.

Instead of sound-absorbing discs on the sliding elements can also be attached to the inside of the sections a sound absorbing tape from approx. 30 mm to 40 mm wide be stuck on. Extensions of the sliding elements run through holes in this band to the sliding elements with the To connect sections.

Another sound absorbing tape is preferably applied the inside - on the sections - where the Sliding elements in special brackets on the inside of the Sections can be attached to the lintel and floor.

By applying these sound absorbing tapes between the sliding elements on the one hand and the fastening elements of sliding elements and / or rollers on the other hand are the vibrations of the gate and thus the noise 50% to 60% reduced when opening and closing.

In the case of lighter gates - weight approx. 10 kg / m ² - the same sliders can be used instead of rollers as a lintel guide for side sectional gates.

In the case of heavy side sectional doors of approx. 20 kg / m ² , the sliders are only used for the floor guide and for the lintel guide. The suspension on the lintel is still carried out by casters for weight reasons.

The advantage of using sliders also for lintel suspension is based essentially on the fact that one also at garage entrances without falling thanks to the use of sliding elements no headroom loses.

The sliders can also be in one piece and in the holes the sections are clipped or snapped.

Sections for gates with a width of up to are preferred 4500 mm or a height up to 3000 mm reinforced by the fact that the longitudinal edges of the individual sections at the junctions approx. 20 mm deep. Two abutting Sections are preferably connected to one another by that a reinforcement profile arranged over the parallel Folded sections inserted and with these sections is screwed. This is on the outside of the sections Screw connection invisible.

With these reinforcement profiles it is possible to install overhead sectional doors up to a width of 4500 mm and side sectional doors to be carried out up to a height of 3000 mm without the overall construction to change. The cornering will in no way adversely affected by the reinforcement profiles.

Fig. 1 shows a ceiling door with a door leaf 10 in it closed position. Four sections 12 of the door leaf 10 are visible. The sections 12 meet longitudinally at joints 14 together and are releasably connected there. Each section 12 has a left and a right end face 16 on. The sections 12 consist of sheet steel, aluminum sheet or plastic and are due to horizontal bevels profiled so that the door leaf 10 in the transverse direction of the Sections 12 is elastically bendable. If the door leaf 10 to Open pushed up, so it can be a relatively tight Follow the curve to a horizontal position, for example near a garage ceiling. At the lower edge of the door leaf 10, a rubber seal 18 is provided which with the door leaf 10 closed on a floor 19 of the building or lies against a lower threshold and seals the door.

In Fig. 2 is a side gate in a similar design shown. The sections 12 are vertical along their length arranged. The longitudinal joints 14 and the folds of the Profiling is also vertical. The door leaf 10 is therefore rigid in the vertical direction, but in the horizontal direction Flexible in the direction. It will open from the in Fig. 2 position shown pushed to the right and passes through a curve on the right in FIG. 2, whereby the Door leaf 10 perpendicular to the plane of the drawing and in the viewing direction is redirected to the rear. The rubber seal also serves here 18, the closed door leaf 10 down, for example to seal against the bottom 19.

3a and 3b is an embodiment of a slider 20, which has a circular outline and is designed in two parts. A first half 22 of the slider 20 has a polished, slightly spherical sliding surface 24 on, a sound-absorbing intermediate layer designed as a disc 26 made of an elastic rubber material and one Extension 28 with an inner, provided with elastic ribs Hole 30. Correspondingly, a second half 32 a sliding surface 34, a disc-shaped elastic intermediate layer 36 and an extension 38 with an outer Toothing is provided. The extension 38 is set up to to be inserted into the bore 30 of the extension 28 where he held securely by the inner ribs of the extension 28 becomes. In an alternative embodiment, the two extensions 28 and 38 have matching screw threads, so that the two halves 22 and 32 of the slider 20th are screwed together.

The sliding surface 24 is, as shown in Fig. 3b, slightly spherical and falls evenly on all sides. She has one middle, approximately flat section, which is the actual Sliding section 25 forms and normally all over is in contact with running or guide surfaces. The outline of the slider 24 is circular with a diameter of approx. 15 - 20 mm.

The embodiment shown in Fig. 4a and 4b Slider 20 has a rectangular outline with rounded Corners on. The sliding surfaces 24 and 34 and the intermediate layers 26 and 36 also have this outline. Furthermore, the Extension 28 square or rectangular, so that this slider 20 is secured against twisting when it is in a Extension 28 corresponding, square or rectangular Hole on a section 12 is inserted.

5a and 5b show a one-piece slide 40 with a sliding surface 42, which is a central, approximately round Has sliding section 43. The one containing the sliding surface 42 Section of the slider 40 is through a circumferential groove 44 of an extension 46, which tapers as a cone Section 46 is formed separately. This Slider 40 is inserted into a hole whose diameter is slightly smaller than the largest outside diameter of the Extension 46 so that the slider 40 with its groove 44 is secure is held in the bore. The extension is preferably 46 axially slotted several times (not shown in FIG. 5a).

In the embodiment alternatives shown in FIGS. 6a and 6b of the one-piece slider 40, the groove 44 is only a little deepened (left in Fig. 6a) or completely omitted (in Fig. 6a right). The extension 46 is approximately a prism with five-sided Base area designed and has several axial incisions 48 on. While the extension 46 relaxed in its State to its end facing away from the sliding surface 42 somewhat widened towards the incisions 48 be radially compressed so far that it becomes this Slightly tapered towards the end. The extension 46 can then in a corresponding pentagonal bore 17 (in Fig. 12) or 107 (in Fig. 11) are inserted, and the slider 40 becomes reliable held in bore 17 or 107.

In Fig. 6a left the extension 46 is eccentric on the slider 40 attached while it is in the in Fig. 6a slide 40 shown on the right is located centrally on slide 40. In both cases, the slider 40 is in the bore 17th or 107 can be used in several different angular positions and secured there against twisting. The sliding surface 42 has an eccentric, as shown in Fig. 6b Sliding section 43. Depending on how the slider 40 in the hole 17 or 107 is inserted, the comes Sliding portion 43 in contact when opening and closing the gate with several slideways, each by a few Are millimeters apart. The fact that the sliding sections 43 can be set to different slideways, the total life of the gate is extended. A higher one This does not result in assembly effort, because if when assembling the gate not on the orientation of the sliders 40 is respected by the random orientation of the sliders 40 with high probability all possible slideways used.

As shown in Fig. 7, in one embodiment a plurality of sliders 20 of the gate according to the invention arranged on the end faces 16 of the sections 12. The sliders 20 lie with their sound-absorbing intermediate layers 26 and 36 on both sides of the sections 12. The extensions 28 and 38 pass through openings (which are not shown in Fig. 7 are and similar to the openings 17 in Fig. 12, but with circular outline, are designed) in the sections 12. One half 22, 32 of each slide 20 protrudes over the outer Limiting levels of the profiled sections 12 beyond and can come into contact with running tracks or running surfaces.

At the joints 14, the sections 12 each have a right angle folded section 52. The folded sections 52 abut each other directly. A stiffening profile 50 is pushed onto the folded sections 52. It covers the sharp ends of the folded sections 52 and stiffen the door leaf 10 in the longitudinal direction the sections 12. The folded sections 52 and the stiffening profile 50 are connected by a screw 54 firmly connected but removable. Through the stiffening profile 50, especially with extra wide gates, the Wind resistance of the gate increased.

In the recessed sections of the Sealing pieces 56 are inserted into the profile of the door leaf 10 and held by the sliders 20 on the door sections 12. The sealing pieces 56 are bent out of sheet metal in a J-shape (or in a suitable form made of plastic) and each have a sealing section 58 which is approximately in one level with the outwardly projecting profile sections of the door leaf 10. Through the sealing pieces 56 ensures that snow and rain do not fall back through the Profile sections in the building, for example the garage that can be whipped into. In an alternative implementation can also be glued on sealing pieces (not shown) made of closed-cell elastic Foam can be used.

In Fig. 8 is part of the guiding mechanism of the gate according to shown an embodiment. The door leaf 10 is located itself in its open position. From the door leaf 10 8 is only a section of the lowest section 12 as well the lower rubber seal 18 shown. A track 60 is firmly connected to a door frame built into the building. The running rail 60 points horizontally into the building protruding portion 62, a vertical portion 64 near the gate opening and a connecting these two sections curved intermediate section 66. Above the curved one Intermediate section 66 is another guide 68 for the door leaf 10 with a lower surface 70, a middle one Surface 72, an upper surface 74 and a stop 76 shown. A roller 78 of the door leaf 10 is over an axis 80 connected to the lower edge of the lowest section 12.

If the door leaf 10 from the position shown in Fig. 8 pulled down, the roller 78 is first between the curved intermediate section 66 of the running rail 60 and the lower surface 70 out. The lower surface 70 urges the roller 78 down and causes the door leaf 10 approximately follows the curvature of the running rail 60. there a certain amount of force must be applied to Transverse direction of the sections 12 elastically bendable door leaf 10 deform accordingly. The roller 78 has the area overcome the lower surface 70, it comes into contact with a vertical section 86 of the door frame. The roller 78 is then between the vertical section 64 of the track 60 and the vertical frame 86 out. The door leaf 10 can can be closed vertically downwards by further pulling. The vertical frame section 86 also has an attached one Plastic profile with a sealing lip (similar to the profile 142 and the sealing lip 144 in Fig. 17) on which the sliders 20 slide and rest with the door leaf 10 closed. The sliders 20 only touch when the door leaf 10 is closed this plastic profile and no metal parts, so the gate does not rattle even in strong wind.

In order to balance the weight when closing the gate to provide increasingly vertically hanging door leaf 10 is a On the one hand, rope 82 is suspended in the axis 80 of the roller 78 and on the other hand with a weight compensation device connected in the form of a pulley. The one shown in Fig. 9 Weight balancer is in an upper horizontal Rail 88, near the opened door leaf 10, attached. An upper section of the rail 88 forms the horizontal Section 62 of the track 60. The weight balancer has several coil springs running in parallel 90 on the one hand in a fixed end piece 92 and on the other hand in a displaceable in the rail 88 End piece 94 are inserted. The sliding end piece 94 acts on the cable 82 via a deflection roller 95.

9, springs 90 are in their relaxed position shown with the door leaf 10 open. While closing of the door leaf 10, the springs 90 are tensioned. The steady increasing spring force becomes the lower edge through the rope 82 of the door leaf 10 transmitted so that the user when closing only has to exert a relatively small, even force.

In the open position of the door leaf shown in FIG. 8 10, the rope 82 runs essentially horizontally. At the Closing the door leaf 10, the rope 82 by two pulleys 84 deflected in a vertical direction, namely first from the upper pulley 84 and further Also close from the lower pulley 84. This will a curve of the rope 82 is reached. Will the door leaf 10 opened again, the rope 82 separates shortly before the door leaf 10 reaches its position shown in FIG. 8 has again grooves of the pulleys 84.

If the door leaf 10 of the normal shown in Fig. 8 Open position pushed back a little (in Fig. 8 after left) until the guide roller 78 is no longer on the lower one Surface 70 of the further guide 68 is in contact with it the door leaf 10 by its resilient restoring force. The guide roller 78 thereby comes into contact with the upper one Surface 74. If the door leaf 10 is now pulled to the right in Fig. 8 the guide roller 78 between the top Surface 74 and the central surface 72 towards the Vertical frame 86 guided up to the stop 76. Through the Slope of the central surface 72 and the fact that the Stop 76 a little below the lowest point of the middle Surface 72 is arranged, the door leaf 10 comes into a safe open rest position (locking position), in the there is no risk of the door leaf 10 accidentally falling shut.

10 shows a side door in which an upper, Track 96 designed as a lintel frame made of powder-coated Metal a horizontal tread 98 for casters 100 of the door leaf 10. The rollers 100 are attached by means of axes 101 to brackets 102 which are aligned with the upper End faces 16 of the door sections 12 are screwed. The Track 96 also has a vertical and running direction of the door leaf 10 arranged rail section 105, whose broad side visible in FIG. 10 has a sliding region 104 forms. Sliders 20, the brackets 102 and others Brackets 106 are arranged, are in contact with the sliding area 104. The sliders 20 ensure a quiet Door movement when opening and closing the door leaf 10.

Since the door leaf 10, when it is opened or closed, itself gently stretches or squeezes (about 10 mm to 15 mm for a wide door with approximately 3500 mm to 4500 mm Width), is a glued, sound absorbing, elastic Steel or plastic band 108 provided that in the direction of travel the sections 12 is arranged. This band 108 is approx 30 mm to 40 mm wide and approx. 0.3 mm to 0.4 mm thick. The Band 108 prevents the annoying pushing or pulling apart of the profiled door leaf ("accordion effect"). In addition, by sticking the tape 108 the entire door leaf 10 with a permanently elastic adhesive soundproofed. The band 108 is near the top of the Door leaf 10 glued, and a corresponding tape is located itself near the bottom.

As shown in Fig. 10, the tape 108 is at the butt joints 14 of the sections 12 interrupted. In an alternative implementation however, it is guided in one piece over all sections 12, or the bands 108 of two sections are over the section boundary connected together. The tape 108 provides a stabilizing element that is also sound absorbing acts.

10 is an alternative embodiment of the connection section 12 (especially for lighter goals), in which an angled section 54 of a section 12 U-shaped for reinforcement and around the folded Section 54 passed around another section 12. As well 7, a screw connection 54 connects the two sections 12th

In an alternative embodiment of the gate shown in FIG. 10 are 20 one-piece instead of the two-piece sliders Sliders 40 used, preferably those according to Fig. 6a and Fig. 6b with polygonal extension 46. The bracket 106 are designed according to FIG. 11 and have two fastening bores as well as a polygonal (here pentagonal) opening 107 corresponding to the extension 46. As with 6a and 6b, the eccentric run Sliding sections 43 of the sliders 40 on different Tracks on the sliding area 104, depending on, in which rotational position the slider 40 in the opening 107 is used. This results in a relatively large overall Surface of the sliding area 104 in contact with the sliders 40, so that the sliding area 104 and an existing thereon Slide coating (for example a powder coating) wear out less quickly.

In Fig. 12 it is shown that in this embodiment alternative of the gate also the sections 12 polygonal on their end faces 16 Have mounting holes 17 in the sliders 40 can be used. The end faces 16 and the sliders Reach behind 40, as with reference to FIGS. 13 and 14 rail section 105 will be described later.

Another embodiment variant of FIG Connection of two sections 12 at their longitudinal joint 14 shown. Here, the section 12 on the left in FIG Interior projecting, curved portion 53 with approximately circular cross-section. A corresponding section 55 is formed on the right section 12 in FIG. 12. The section 55 encloses the section 53 at the other convex outer surface. This creates a hinge that connects the two sections 12 in an articulated manner. at the assembly of the gate requires the two sections 12 their sections 53 and 55 only to be hooked into each other.

The gate shown in FIGS. 13 and 14 essentially corresponds that of Fig. 10, only that instead of the two-piece sliders 20 one-piece sliders 40 are used. Out Fig. 13 shows that the upper (shown in dashed lines) Edge of the door leaf 10 engages behind the rail section 105. The rail section 105 has, in addition to that in FIG. 13 visible from a broad side of the rail section 105 formed sliding area 104 a further sliding area 109 (Fig. 14) on that of the other, in Fig. 13 the viewer opposite broad side of the rail section 105 is formed is. This further sliding area 109 is in contact with further sliding pieces 40 (shown in broken lines in FIG. 13), at the top of the door leaf 10 in openings 17th (Fig. 12) are used. This arrangement is the door leaf 10 safely guided along the rail section 105. The path of the roller 100 on the tread 98 is thus clearly defined without further action (For example, profiling the tread 98) is required would.

Fig. 15 again shows the bilateral guidance of the upper one Edge of the door leaf 10 through the vertical rail section 105 of the upper track 96, which with a fall 110 on a ceiling 111 of the building, for example the garage, is firmly connected. Compared to that in Fig. 13 and Fig. 14 embodiment are instead of the one-piece Slide pieces 40 again two-piece slide pieces 20 are provided. A lower edge of the door leaf 10 is guided on the bottom 19. A running rail 112 arranged on the floor 19, shown here is designed as an angle profile, has an approximately vertical upwardly projecting guide portion 114 with an inner Sliding area 116 and an outer sliding area 118 on. The inserted in the lower edge of the door leaf 10 Slider 20 slides on the outer sliding area 118.

The Rather, door leaf 10 can be of guide and support elements in Form of sliders 20 are worn, the bent, horizontal end portions 124 of the bracket 102 are attached and slide on the tread 98. With heavy door leaves 10, this arrangement would result in high tread wear 98 and the management and Guide support elements 20.

The door leaf 10 shown in FIG. 16 has one at the bottom Wood existing section 126, which is similar to Fig. 15 is shown. The floor track 112 is here designed as a T-profile and next to that points upwards projecting guide section 114 anchored in the floor 19, downward section 128. Another is coming the bracket 120 attached two-piece slider 20 in contact with the inner sliding area 116. On the outer sliding area 118, on the other hand, a one-piece slider 40 slides, that with an extension with screw thread in the wood section 126 of the door leaf 10 is screwed.

In the overhead door shown in Fig. 17, there is a split one Side frame 130 provided that a mounting leg 132, a first running rail 134 and a second running rail 136 has. The mounting leg 132 and the running rails 134 and 136 are screwed together. The mounting leg 132 is fixed with a side reveal 138 of the Connected to the building. The first running rail 134 has a folded, Running section protruding towards the gate opening 140 on. A plastic profile is on the running section 140 142 with a sliding area for on the side edge of the door leaf 10 attached to the front (visible side) Sliders 40 attached. The plastic profile 142 serves for sound insulation when opening and closing the door leaf 10 and also has an elastic, profiled sealing lip 144 on, which protrudes towards the gate opening and on the door leaf 10 lies tight. Similarly, the second track 136 a running section 146 projecting towards the gate opening with an attached, sound-absorbing plastic profile 148 on. A sliding surface formed on the plastic profile is in contact with sliding elements 20 on the back of the door leaf 10 are attached to the side edge.
