Description

Sliding door with sliding leaf

Technical Field

The present invention relates to a sliding door having a jamb frame and a sliding sash movably disposed with respect to the jamb frame, particularly in the jamb frame, so as to open and close a passageway of the jamb frame, wherein the sliding sash is disposed in the jamb frame so as to be vertically adjustable in height and horizontally movable with respect to the jamb frame.

Background

The sliding wings of such sliding doors are also called lifting/sliding wings because they are disposed in the jamb frame so as to be vertically adjustable in height with respect to the jamb frame and so as to be horizontally movable with respect to the jamb frame. Furthermore, they are generally provided with multiple layers of glass and preferably have a surrounding wing frame. The sliding leaf can be designed such that in any case the lower frame profile can be lowered into the ground at least in the closed position. So that they can achieve a closure that appears to be frameless to some extent towards the ground.

Sliding fans are also manufactured for relatively large wall openings in order to be able to look as unobstructed as possible out of the space of the building. For this purpose, a sufficiently rigid profile is required which can reliably and torsionally rigidly accommodate the large mass of the wing of such a sliding wing. In the lowered position, the mobility of the wing is different from being normally locked in the raised, displaced position or at least significantly limited with respect to the mobility in the displaced position. It can be provided that the underside of the wing is placed in the lowered position, preferably immovably on the rail.

A lifting fitting for a leaf frame of a sliding window or door is known from DE1559725A1, wherein a pulley is fastened to the leaf frame at the lower part, said pulley rolling on a running surface of a rail, which rail as a whole can be raised and lowered. For this purpose, the webs on the slide rail slide in the slide grooves of the slide rail having inclined slide grooves, which form substantially inclined planes. The principle described is used in DE102016123802, in which the individual sections of the slide rail are provided with wedge-shaped sections downwards, the inclined plane of the respective slide groove being able to be pulled upwards.

The disadvantage of both solutions is that a large actuating force is to be applied when lifting the lower rail (on which the sliding leaf rolls with its rollers) due to the sliding friction to be overcome in the inclined plane provided for assisting and guiding the lifting movement.

Disclosure of Invention

The task of the present invention is to solve the problem, departing from the principles of these documents and going to another path.

To this end, the invention proposes a sliding door having:

a. a frame and a sliding fan arranged in a mode of being capable of moving relative to the frame, wherein the sliding fan is used for opening and closing a channel of the frame,

b. wherein the sliding fan is arranged in the frame of the frame in a manner of vertically adjusting the height and horizontally moving relative to the frame of the frame, and is characterized in that,

c. the sliding fan has a lower rail-shaped running surface, by means of which the sliding fan can slide horizontally on at least one first roller element with respect to the first roller element in the displacement position, the first roller element having one, two or more sliding rollers, the sliding fan being able to slide horizontally on the sliding rollers with respect to the first roller element,

d. the height level of the first roller element can be varied vertically so that the sliding sash together with the first roller element can be placed in a higher displacement position relative to the lowered position from a vertically deeper lowered position relative to the jamb,

e. In order to change the height level of the first roller element, at least one runner roller is provided on the first roller element, which runner roller can roll on at least one corresponding ramp contour track by means of a contour extending at least in sections obliquely to the horizontal.

The sliding door according to the invention is characterized, starting from the features of the preamble, in that the sliding leaf itself has a lower rail-like, rail-like running surface, by means of which the sliding leaf can be moved horizontally relative to the first roller element in the displaced position on at least one first roller element, wherein the first roller element has one, two or more sliding rollers, on which the lifting sliding element can be moved horizontally relative to the first roller element. The height level of the first roller element can be changed vertically, so that the sliding leaf together with the first roller element can be placed in a higher displacement position relative to the lowered position from a vertically deeper lowered position relative to the jamb frame, and vice versa, wherein, in order to change the height level of the first outer roller element, at least one runner roller is provided on the first roller element in addition to the one or more sliding rollers, which runner roller can roll on at least one corresponding ramp contour track by means of a contour extending at least partially obliquely to the horizontal. The one or more inclined sections of the slide groove are correspondingly also referred to as ramps or ramp sections. The term "roller element" also synonymously stands for "roller device".

The term "sliding door" also includes within the scope of this document "sliding window".

According to the invention, the pulley device with the wing is no longer arranged on a lowerable slide rail, which has a running surface. Instead, the pulley device is separated from the wing, which now has a rail-like running surface directly on its underside and unexpectedly no longer is a rail with a running surface, but the pulley device separated from the wing rolls by the rollers of the at least one runner roller into the upper and lower positions on a ramp profile rail which is partially inclined to the horizontal.

This gives itself a significant advantage. Since it is necessary to overcome advantageously only a rolling friction between the respective runner roller and the respective ramp, which is significantly smaller in magnitude than the static friction, in order to lift and lower the pulley device together with the wing slidable thereon on another rail-like contour (on the ramp contour rail) which is designed to be non-lowerable. The energy consumption for moving the sliding fan according to the invention from the lowered position into the displaced position is thereby advantageously correspondingly smaller. Thus, for a motor-driven drive with a varying height level of the lifting slide element according to the invention, advantageously only a relatively small power is required. The functions of the height level change and the displacement of the lifting slide element are advantageously separated from one another, so that the functional carriers, in particular the respective rollers, can be designed in an optimized manner for the respective function. It is also advantageous here if only a lower running surface has to be provided on the sliding leaf itself. Conversely, the pulley means do not have to be mounted on the wing, which significantly simplifies the construction and assembly of the sliding wing. The term "frame" should not be construed too narrowly. The frame may, but need not, be configured to be circumferentially closed. The frame may, but need not, be constructed on four sides at right angles to each other, and the frame may not necessarily be constructed identically on all sides.

In terms of construction, it can be advantageously provided that the ramp contour track is formed in the guide channel in the chute profile, in particular such that the respective roller element is completely lowered into the guide channel in the lowered position. The guide channels can be provided and/or constructed in the frame, for example in the bottom beam of the frame, which is simple and advantageous. But the frame may be constructed independently of this.

The ramp profile rail and the roller element may be moved relative to each other by the rollers.

In this case, according to a first preferred embodiment, it can be provided that the ramp contour rail (in or on the jamb frame) is embodied in a fixed manner and that the height-adjustable roller elements are pulled up horizontally and vertically in a superimposed manner in such a way as to roll on the ramp contour rail and can be lowered in a rolling manner on the ramp contour rail. The variant is structurally well implemented and is characterized by a reliable operation without interference.

However, according to a further, also preferred embodiment, it can alternatively be provided that the ramp contour track is configured to be movable, in particular to be rollably movable, so that it can be moved past the highly variable roller elements, so that one or more rollers of the first roller element roll on its ramp section, which lifts or lowers the first roller element. The variant is structurally well implemented and is characterized by a reliable operation without interference and a particularly defined, precise course of movement.

Both of the above-described embodiments are therefore very advantageous and achieve a defined uniform movement of the sliding fan when the sliding fan is moved from the lowered state to the raised state, and vice versa.

It may be provided that only the (and therefore the first) roller element of the invention is provided. Alternatively, it can also be provided that at least one second roller element is provided on which the sliding fan can be moved horizontally with a lower rail-like running surface, wherein the second roller element has two or more sliding rollers on which the sliding fan can be moved horizontally relative to the second roller element. In this case, it is expedient if the second roller element is aligned with the first roller element at least in the displaced position.

It can be provided that the height level of the second roller element can also be changed vertically. However, it is also often sufficient if the height level of the second roller element cannot be changed vertically. The wing can then be moved from its closed position into an open position on the second roller element. The second roller element itself need not be able to descend. At least advantageously, it is therefore provided that the profile of the gate track has a slope or slope section extending obliquely to the horizontal, on which slope or slope section at least the first roller element can be rolled into a vertically deeper lowered position and into a higher displacement position relative to the lowered position.

Advantageously and in a simple manner, the first roller element and/or the second roller element each have a one-piece or multipart base body in which the roller elements are rotatably mounted. In this case, it is expedient and simple for the respective base body to be formed as a base profile. The function of changing the height level of the lifting slide element can thereby be advantageously focused in a compact structural assembly.

It may be provided that two or more of the slide rollers and/or at least one of the slide rollers are each rotatably supported on a shaft extending through the base body, and that for each base body, one or more of the slide rollers and/or one or more of the runner rollers are provided for a plurality of the shafts.

It is further expedient and simple that the ramp profile rail is fixedly arranged or constructed in a channel of the bottom girder of the transom frame.

This is structurally simple and contributes to a compact design, when a respective one of the runner rollers is arranged coaxially with a respective one or more of the guide rollers.

In a preferred variant, the two or more sliding rollers are rotatably mounted on an axis, wherein the axis passes through two profile webs of the middle section of the base profile and is fixedly mounted in the base profile by the profile webs. A simple and thus advantageous construction is thereby obtained, which can also be assembled in a simple manner.

Furthermore, it has proven to be advantageous if the respective sliding roller has a guide contour on its periphery, which guide contour preferably has a V-shaped cross section, and the profile support of the sliding leaf serves as a rail-like running surface. The profile support can be inserted geometrically correspondingly into the guide contour, in particular into the V-shaped guide contour, of the individual sliding rollers. The corresponding sliding rollers thus additionally and thus advantageously also assume the guiding function of the lifting slide element in addition to the bearing characteristic (i.e. bearing the weight of the lifting slide element).

In a further preferred embodiment, a respective one of the runner rollers is arranged coaxially with one or more of the guide rollers. This advantageously results in a simple construction, since the respective shafts (on which the rollers are arranged coaxially) are multiplexed.

It is also advantageous if the respective runner rollers each have an L-shaped guide contour. The respective chute roller therefore only has to be fixed axially on the shaft at a position axially outside its respective axis.

It may be advantageously provided that the ramp profile track has a plurality of ramps. When the ramp profile rail has a plurality of ramps, it is advantageous if one gate roller rolls on each ramp.

It can be provided here that the inclination angle α of the respective ramp profile track is preferably 5 ° to 60 ° and particularly preferably 20 ° to 40 °. In this way, a ramp is advantageously achieved which is designed to be short and thus to save space, and on the other hand a ramp output force (hook-abtriebskarft) is achieved which is not too large on the ramp and which is to be overcome.

It can advantageously be provided that, for example, a first recess is formed in each case in the respective run-on profile at the bottom of the respective ramp, which first recess corresponds geometrically to the diameter of the respective run-on roller in such a way that the run-on roller is placed in the first recess in the lowered position, and/or that the run-on profile has a second recess in each case at the apex of the respective ramp, which second recess also corresponds geometrically to the diameter of the respective run-on roller in such a way that the run-on roller can be placed in the second recess in the displaced position. The recess achieves that the chute roller is in a stable equilibrium state not only in the lowered position but also in the displaced position, so that the drive does not have to be kept continuously in order to hold the first roller element in the respective position. Conversely, when the lowered or displaced position is reached, the drive can be disconnected or de-energized, which advantageously affects the operation of the drive in an energy-saving manner.

Advantageously, the first roller element is coupled to a drive device, which is provided for rolling the first roller element over a respective ramp by means of a respective runner roller or with a respective runner roller in order to move it from the lowered position into the displaced position and vice versa.

However, it is also possible to design the slide rail to be movable, in particular rolling, and to couple it to a drive.

The drive device may be configured as an electrically operated or fluid operated lift cylinder. The lifting cylinder may be arranged (preferably not visible) in the bottom beam.

In this way, a simple-to-operate sliding door is obtained for the operator and a drive device that can be integrated into the structure is simple.

It is also advantageous if the slot spaces of the sliding leaf towards the upper and/or lower horizontal transom or bottom beams are sealed by seals, for example by two brush seals, respectively. As a result, a flexible, insensitive and advantageous seal is provided with respect to the vertical movement of the lifting slide element which occurs when the lifting slide element is lifted from the lowered position into the displaced position and conversely lowered from the displaced position into the lowered position.

In such sliding fans, good insulation is also generally desired. The sliding rail of such a sliding leaf can therefore, but does not have to, be composed of at least two or more profiles, for example aluminum profiles, which are fixedly connected to one another by means of insulating webs (also referred to as insulating webs). By means of such a separation, which is usually caused by a tab made of plastic, an effective thermal separation of the two profiles can be achieved, in which a wing is guided in each case in a displaceable manner.

The invention also provides a method for moving a sliding leaf of a sliding door according to the invention, wherein the height level of the second roller element can also be changed vertically, wherein the sliding leaf is first placed in a raised position from a lowered position by lifting a first roller element, then the sliding leaf is moved from the first roller element onto the second roller element in a flush position with the first roller element, and then the second roller element is placed in a lowered position of the second roller element together with the sliding leaf. In particular, this ensures that the sliding fan is lowered in such a way that its glass pane extends to the ground and that it prevents unintentional movements.

Detailed Description

Positional and azimuthal relationships as used hereinafter, for example, "on", "vertical", "horizontal", "right", "left" relate to the drawing planes of the respective drawings.

Fig. 1a shows a sliding door with a jamb 300 inserted into a wall opening, in which a wing is guided movably, and which wing is also referred to below synonymously as lifting/sliding leaf 1 or simply sliding leaf 1.

The transom 300 is fitted into the wall opening. In which the sliding fan 1 is guided movably. This is shown in figure 1a in a closed position in which the sliding sash 1 closes the channel D through the transom 300 and wall opening. In addition to the lifting slide fan 1 shown, as shown in fig. 1a to 1e, a fixed glass 2 may be provided. But it is also possible to arrange one or more further sliding wings 1 (not shown) in the transom or in the wall opening.

In the transom 300, the horizontal guide channel 3 is downwardly adjacent to the wall opening, which is below the guide channel described herein as "OKFF"Oberkante Fertigfuβboten: upper edge of the finished floor) marked floor level. The sliding sash 1 can be lowered into the guide channel 3 in the lowered position (as it is shown in fig. 1 a), for example such that in the lowered position a lower frame profile (not shown here, see fig. 3) of the sliding sash 1 is not visible.

The sliding fan 1 is able to slide with respect to and on the first roller element 50, the height level of which is variable. For this purpose, the sliding fan has a rail-like running surface LF on its underside.

By means of the change of the height level of the first roller element 50, which is shown in fig. 1b, 1c and 1d and which will be described in more detail, the sliding fan 1 can be brought out of the guide channel 3, i.e. out of the lowered position, into a displaced position on the floor plane OKFF. From the moved position, the sliding fan 1 can be moved from the closed position shown in fig. 1a into a sliding position as shown in fig. 1D, in which the channel D is opened. For this purpose, the guide channel 3 has here a second roller element 60, which is aligned with the first roller element 50. The first roller element may be substantially as long as the wing. But it may also be shorter or in particular longer than the wing. It is even possible to be so long that no further roller elements are required, but rather the wing can be moved directly onto the sole roller element into the open position.

In fig. 1c, the sliding fan 1 has been moved out of the closed position in the moved position and in the direction of the fixed glass 2. In this case, a part of the lifting slide element is guided on the first roller element 50 and another part of the lifting slide element is guided on the second roller element 60, so that its height level can optionally also be changed as shown in fig. 1 e.

In fig. 1d, the sliding fan 1 reaches the open position in its moved position. In fig. 1e, the sliding fan 1 can also optionally be lowered into a lowered position in the open position.

Fig. 2 shows a top view of a section of the sliding fan 1 according to fig. 1a or 1 b. A mullion 300 is inserted into the wall opening, wherein the two lateral upright mullion beams 310, 320 are shown. Also shown in cross section is a central vertical transom 350, which belongs to the fixed glass. Furthermore, a bottom beam 330 is shown, which can be preferably embodied with its upper edge flush with the floor plane OKFF, in order to be able to realize an advantageous unobstructed passage and thus can be accommodated completely by the guide channel 3.

The left and right upright frame rails 310, 320 may have two shells 311, 312 and 321, 322, respectively, which are connected to each other by spacer tabs 313, 323, respectively. The shells 311, 312 or 321, 322 can be made of geometrically identical profiles as shown in fig. 2. This is advantageous but not mandatory. The housings 311, 312 and 321, 322 may each have one or more cavities. The spacer tabs 313, 323 are preferably made of a plastic material. The housing 311, 312 or 321, 322 is preferably made of light metal by an extrusion process. Alternatively, the housing 311, 312 or 321, 322 may also be made of additional materials and/or by additional manufacturing processes.

The lateral upright frame girders 310, 320 of the frame 300 thus formed each have an E-shaped cross-sectional geometry, which are arranged here in mirror image to one another in the frame 300 embodied. The left first slot space 314 and the left second slot space 315 and the right first slot space 324 and the right second slot space 325 can be closed off with respectively lockable cover profiles 316, 326.

In the example of fig. 2, the second slot space 325 on the right of the vertical transom 320 in the area where the glass 2 is fixed is closed with a cover profile 326, while the first slot space 314 on the left of the vertical transom 310 on the left in the area of the sliding sash 1 is closed with a cover profile 316. The cover profiles 316, 326 are preferably made of light metal by an extrusion process. Alternatively, the cover profiles 316, 326 can also be made of additional materials and/or by additional manufacturing processes.

The fixed glass 2 is embedded in the bezel frame 200. The slot spaces 211, 221 of the bezel frame 200 are sealed against the surroundings by means of elastic seals, which each rest against the fixed glass 2.

Here, a left vertical trim profile 210 and a right vertical trim profile 220 of the trim frame 200 of the fixed glass 2 are shown. The bezel frame 200 holding the glass 2 can also have additional bezel profiles. For example, upper and lower trim profiles (both not shown here) are conceivable. The trim profiles 210, 220 are preferably made of plastic material by an extrusion process. Alternatively, the trim profiles 210, 220 may also be made of additional materials and/or by additional manufacturing processes.

The fixed glass 2 is engaged with its right vertical bezel section 220 of the bezel frame into the right second slot space 325 of the right vertical transom beam 320. The gap created between the insert frame profile 220 and the second slot space 325 is sealed in each case by means of a sealing profile.

The fixed glass 2 is here also joined with its left vertical frame profile 210 into a slot space 351, which is formed by a frame beam 350 arranged vertically in the middle. The middle vertical transom 350 defines a channel D in combination with the cover profile 316 closing the left first slot space 314 in the region of the left vertical transom 310.

A bezel frame retention profile 352 is inserted into the slot space 351 of the center vertically disposed transom 350 and is preferably fixedly attached to the transom 350. The fastening connection can be produced by a cohesive connection, for example, adhesive. The left vertical frame profile 210 of the frame 200 of the fixed glazing 2 is embedded in the frame holding profile 352 and is fixedly connected to the frame holding profile 352 by one or more form-locking connections. The resulting gap is sealed by means of a corresponding sealing profile.

The glass of the sliding sash 1 is embedded in the sash frame 100. The slot spaces 111, 121 of the wing frame 100 are sealed against the surroundings by means of elastic seals, which are each in close contact with the glass.

Here, the left vertical sash profile 110 and the right vertical sash profile 120 in the sash frame 100 of the glass of the sliding sash 1 are shown. The glass sash frame 100 of the lifting slide element may also have further sash frame profiles. It is conceivable to use, for example, an upper horizontal wing frame section 140 and a lower horizontal guide frame section (not shown here, respectively, see fig. 3). The wing frame profiles 110, 120, 140, 150 are preferably made of plastic material by an extrusion process. Alternatively, the wing frame profiles 110, 120, 140, 150 can also be made of additional materials and/or by additional manufacturing processes.

The glass of the sliding sash 1 is inserted with its left vertical sash profile 110 into the left second slot space 315 of the left vertical transom 310. The left vertical sash profile 110 can be provided with a protective cap 112, which is snapped onto the sash profile 110. The gap created between the wing frame profile 110 and the second slot space 315 is here each sealed with a sealing profile.

The glass of the sliding sash 1 is also inserted here with its right vertical sash profile 120 into a slot space 131, which is formed by the closing profile 130.

The retaining profile 132 engages in the slot space 131 of the closing profile 130 and is preferably fixedly connected to the closing profile 130. The fastening connection can be produced by a cohesive connection, for example, adhesive. The right-hand vertical sash profile 120 of the glass of the sliding wing 1 is embedded in the holding profile 132 and is fixedly connected to the holding profile 132 via one or more form-locking connections. The resulting gap is sealed by means of a corresponding sealing profile.

Fig. 3 shows a side view of the sliding fan 1 in section. Here, the bottom beam 330 and the upper cross beam 340 are shown by the transom 300.

The upper cross beam 340 may be constructed similar to the left vertical transom 310 (see fig. 2) and the right vertical transom 320 (see also fig. 2). This is advantageous but not mandatory. Unlike the upright frame beams 310, 320, the upper cross beam 340 has at least one or (as shown in fig. 3) a plurality of guide surfaces 343, 344 in the first housing 341 and in the second housing 342, respectively.

The guide surfaces 343, 344 are part of the guide support 40 of the sliding sash 1. In this connection, it is pointed out that the guide support 40 of the sliding sash 1 is guided only along the guide surfaces 343, 344 when moving from the closed position into the open position, but is not loaded, i.e. in particular does not bear the weight of the sliding sash 1. In response to this, the guide support 40 functions in accordance with the floating support principle with respect to the sliding movement of the elevating slide fan 1.

The guide support 40 can have one or more guide carriages 41, on which at least one or more (here two) guide rollers 42, 43 are rotatably arranged, which can roll on the guide surfaces 343, 344 and thus guide the sliding fan 1 in the upper region during sliding. The sliding leaf can therefore also have a guide in its upper region relative to the jamb frame and possibly a displacement drive.

For this purpose, the sliding leaf 1 is connected to the guide slide/slides 41 via a profile rail 44 and a pin 45. The profile rail 44 can be connected to the upper horizontal leaf profile 140 in a form-locking manner with respect to a direction perpendicular to the displacement direction, so that a fixed connection is achieved during the lifting from the lowered position to the displacement position.

A belt lock can be integrated into the guide carriage 41, with which belt lock a belt (not shown here) of a winding drive is fastened to the guide carriage 41, so that the guide carriage 41 can be moved by means of the winding drive in an actuator manner. Preferably, the drive belt is a toothed belt and the actuator is an electric motor.

The glass of the lifting slide element engages in the slot space of the upper horizontal leaf frame profile 140 and is sealed from the surroundings by the sealing profile. In addition, the glass of the lifting slide element is sealed by the two brush seals 346, 347 toward the notch space 345 of the second housing 342 of the upper horizontal transom. As a result, a flexible, insensitive and advantageous seal is provided with respect to the vertical movement of the lifting slide element which occurs when the lifting slide element is lifted from the lowered position into the displaced position and conversely lowered from the displaced position into the lowered position.

The slot space 348 of the first housing 341 is closed in the region of the channel D by the lockable cover profile 349.

The bottom beam 330 may be (as shown in fig. 3) constructed similar to the left hand upright transom 310 (see fig. 2) and the right hand upright transom 320 (see also fig. 2). This is advantageous but not mandatory.

The bottom beam 330 may therefore have two shells 331, 332, which are each connected to one another via a separate tab 333. The shells 331, 332 can be made of geometrically identical profiles as shown in fig. 3. This is advantageous but not mandatory. The housing 331, 332 may have one or more cavities. The spacer tab 333 is preferably made of a plastic material. The housings 331, 332 are preferably made of light metal by an extrusion process. Alternatively, the housings 331, 332 may also be made of additional materials and/or by additional manufacturing processes.

The bottom beams 330 of the transom 300 thus constructed have an E-shaped cross-sectional geometry, respectively, therein. The left slot space 334 is closed here by a lockable cover profile 335, which forms the bottom of the channel D. The right slot space 336 accommodates the first and second roller elements 50, 60 of variable height (not shown here, see fig. 4 b).

The bottom beam 330 is preferably embedded in the guide channel such that the bottom beam 330 is completely accommodated by the guide channel and is thereby advantageously not visible from the outside.

The first roller element 50 is shown here in cross section with a first height variable. The first roller element 50 (shown here in the displaced position) has a basic profile 51. In this basic profile 51, at least two, in this case a plurality of sliding rollers, are rotatably supported in the central section 511 of the cross section by an axis 53. The axis 53 passes through the two profile webs 513, 512 of the central section 511 and is fastened by the profile webs 513, 512 in the base profile 51. The two profile webs 513, 512 geometrically correspond to the corresponding slots 337 of the bottom beam 330. The slot 337 is provided for receiving the profile webs 513, 512 and the outer region of the respective slide roller 52 in the lowered position of the lifting slide fan 1 (see, for example, fig. 4 a).

The slide rollers 52 each have a guide contour 521 on their periphery, which preferably has a V-shaped cross section. The cross section may alternatively have another geometry. For example, a U-shaped cross section is also conceivable. The sliding rollers 52 thus additionally assume the guiding function of the lifting slide fan 1 in addition to the bearing properties (i.e. bearing the weight of the lifting slide element). By "guided" is meant that, for the sliding leaf 1, by way of the guide surfaces 343, 344, 42 of the sliding roller 52 or by way of the guide contour 521, no more freedom of movement is allowed in space, so that only a substantially linear movement of the lifting slide element from the closed position into the open position in the sliding roller 52 or on the sliding roller 52 is possible.

For this purpose, the profile holders 151, which are fastened here to the lower horizontal leaf frame profile 150 of the sliding leaf 1, are geometrically correspondingly inserted into the V-shaped guide contours 521 of the respective sliding roller 52. Alternatively, the profile support 151 can also be integrally formed on the lower horizontal leaf profile 150.

Furthermore, at least one, in this case two, runner rollers 54, 55 are rotatably mounted on the respective shaft 53 at its two free ends, which are each fixed externally in the axial direction by a shaft stop ring in order to prevent axial displacement on the shaft 53. In this connection, the respective runner roller 52 and the two respective runner rollers 54, 55 are arranged coaxially with respect to one another. This is advantageous but not mandatory. For example, it is also conceivable that the axis 53 is curved such that the respective corresponding run-on roller 54, 55 is not arranged coaxially with the respective slide roller 52.

The respective runner rollers 54, 55 each have an L-shaped guide profile, which each reminds a railway wheel (Eisenbahnrad), wherein the guide profiles are preferably arranged in pairs mirror images of one another. With this guide contour, the runner rollers 54, 55 roll on at least one, in this case two runner profiles 56a, 56b, respectively, which are fixed in position in the bottom beam, for example in the second housing 332 of the bottom beam 330. The fastening of the runner profiles 56a, 56b is carried out here by screws, but the fastening can alternatively be carried out in another way.

The first roller element 50 is shown in a lowered position in fig. 4 a. The slot space 336 of the glass of the lifting slide fan 1 to the right of the bottom beam 330 is sealed from the surroundings by brush seals 338, 339. The two brush seals 338, 339 rest in each case on the lower horizontal guide frame profile 150 of the glass of the lifting slide fan 1. As a result, a flexible, insensitive and advantageous seal is provided with respect to the quasi-vertical movement of the lifting slide element which occurs when the lifting slide fan 1 is lifted from the lowered position into the displaced position and conversely lowered from the displaced position into the lowered position.

In the lowered position of the sliding sash 1, the lower horizontal guide frame profile 150 is located completely in the right-hand slot space 336, so that it is not visible from the outside. In the lowered position, a visually attractive and thus advantageous "glass-only optical system (Nur-Glas-Optik)" of the sliding fan 1 is thereby achieved.

It can be seen that the slide roller 52 is submerged in the slot 337 of the housing 332 to the right of the bottom beam 330. Furthermore, the base profile 51 is supported on the right-hand outer shell 332 of the bottom beam 330 by two further profile webs. The two runner rollers 54, 55 rest against the respective runner profiles 56a, 56 b.

The bottom beam 330 is shown in cross section in fig. 4 b. For the sake of clarity, the illustration is rather kept schematic. It can be seen that the first height of the first roller element 50 and the second roller element 60 is variable. The basic profile 51 of the first roller element 50 is coupled to a drive. The drive is embodied here as an electric lifting cylinder 57. The base profile 51 is thus coupled in an articulated manner to the piston rod of the electric lift cylinder 57. The electric lifting cylinder 57 is fixed with its end facing away from the piston rod to the bottom beam 330. The motorized lift cylinder 57 is dimensioned such that it is not visible from the outside or is accommodated in the slot space 336 (to the right in this case) of the bottom beam 330.

Furthermore, one of the runner profiles 56a and several of the sliding rollers 52 and runner rollers 55, 54 are shown. The runner profiles 56a, 56b each have at least one, preferably a plurality of ramps 561a, 561b, 561c. The inclination angle α of the respective ramps 561a, 561b, 561c is preferably 5 to 60 ° and particularly preferably 20 to 40 °.

On the bottom of the respective ramp 561a, 561b, 561c, a respective one of the first grooves 562a, 562b, 562c is added to the respective runner profile 56a, 56 b. The first grooves 562a, 562b, 562c each geometrically correspond to the diameter of the respective runner roller 54, 55 and the respective runner roller 54, 55 can achieve a stable equilibrium state in the lowered position shown here of the first roller element 50.

Furthermore, the runner profiles 56a, 56b have a second groove 563a, 563b, 563c at the "apex" of the ramps 561a, 561b, 561c, respectively. The respective second groove 563a, 563b, 563c also geometrically corresponds to the diameter of the respective runner roller 54, 55, and the respective runner roller 54, 55 can achieve a stable equilibrium state in the displaced position of the first roller element 50 shown in fig. 5 b.

The drive means for lifting the roller elements and the wings, preferably here the electric lifting cylinders 57, are provided for rolling the base profile 51 (and thus the sliding wings 1) over the respective ramps 561a, 561b, 561c by means of the respective runner rollers 54, 55 in order to move the first roller element 50 from the lowered position (see fig. 4 b) into the moved position (see fig. 5 b) and vice versa.

In this case, it is advantageously only necessary to overcome a rolling friction between the respective runner roller 54, 55 and the respective ramp 561a, 561b, 561c, which is significantly smaller in magnitude than the static friction. Since both can preferably be made of metallic materials, for example steel, the rolling friction or rolling resistance of the respective chute rollers 54, 55 is correspondingly small. The electric lifting cylinder 57 can thus advantageously be dimensioned correspondingly small in terms of its power. Likewise, the energy consumption for moving the sliding fan 1 from the lowered position into the moved position is advantageously correspondingly small.

Furthermore, the first recesses 562a, 562b, 562c and the second recesses 563a, 563b, 563c each have the effect that the chute rollers 54, 55 are in a stable equilibrium state both in the lowered position and in particular in the displaced position, so that the electric lift cylinder 57 does not have to be kept continuously in order to reliably hold the first roller element 50 in the respective position. Conversely, when the lowered or displaced position is reached, the electric lift cylinder can be disconnected or de-energized, which advantageously affects the operation of the electric lift cylinder in an energy-saving manner.

A second roller element 60 is also shown in fig. 4 b. The second roller element 60 is similar in construction to the first roller element 50 of variable height, however without means for changing the height, i.e. without the runner profiles 56a, 56b, the runner rollers 54, 55 and the electric lift cylinder 57. In this regard, the second roller element 60 is preferably permanently located at the level of the height of the displacement position. Alternatively, the second roller element 60 may also be height-adjustable (see fig. 1e for this).

Fig. 5a and 5b show the sliding fan 1 in the moved position. Correspondingly, the respective runner rollers 54, 55 are located in the second grooves 563a, 563b, 563c at the "apexes" of the respective slopes 561a, 561b, 561c, respectively.

Fig. 6a shows a fixed glass 2 in addition to the lifting slide element. The sliding fan 1 is here in the lowered position (see fig. 4 a). The lower horizontal bezel profile 230 of the fixed glass 2 is also placed in the left slot space 334 of the bottom beam 330 on the base profile 51, which is not yet height-adjustable here.

Fig. 6b shows the sliding fan 1 in the lowered position (see fig. 4 a) together with the channel D.

In fig. 6c, the sliding fan 1 and the first roller element 50 as well as the second roller element 60 are shown in the lowered position (see fig. 4 b).

Fig. 7a shows a fixed glass 2 in addition to the lifting slide element. The sliding fan 1 is here in the displaced position (see fig. 5 a). The lower horizontal frame section 230 of the fixed glass 2 is also placed in the left slot space 334 of the bottom beam 330 on the base section 51, which is not yet height-adjustable.

Fig. 7b shows the sliding fan 1 in the moved position (see fig. 5 b) together with the channel D.

Fig. 7c shows the sliding fan 1 and the first roller element 50 and the second roller element 60 in the displaced position.

Fig. 8 shows a part of the runner profiles 56a, 56b and the runner rollers 54, 55. It can be seen that the first and second grooves 562a, 562b, 562c, 563a, 563b, 563c and the corresponding slopes 561a, 561b, 561c therebetween. In this case, the chute rollers 54, 55 are each shown by way of example twice in the lowered position of the sliding fan 1 and once in the displaced position. In this case, the run rollers each represent a lowered position in the first grooves 562a, 562b, 562c, or a displaced position in the second grooves 563a, 563b, 563c, and are therefore each in a stable equilibrium state.

Fig. 9 to 11 show a further lower element of a sliding door 1, in particular a lower frame region, with a transom 300 and a lifting/sliding leaf 1 (also referred to as sliding leaf) which is arranged movably relative to the transom 30 for opening and closing a channel D of the transom 300, wherein the sliding leaf 1 is arranged in the transom 300 so as to be vertically adjustable in height relative to the transom and also horizontally movable.

The sliding door 1 can be configured, for example, essentially in the manner according to fig. 1 and 2, and thus in its upper region, wherein, however, the lower element of the sliding door can be configured in a further manner as shown in fig. 9 to 11.

As can be seen in fig. 9, the lifting and sliding fan 1 of this embodiment also has a lower rail-like, rail-like running surface LF, with which the lifting and sliding fan can be moved horizontally relative to the first roller element 1050 in the displacement position on at least one first roller element 1050, wherein the first roller element 1050 has one, two or more sliding rollers 1052, on which the sliding fan 1 can be moved horizontally relative to the first roller element 50. The roller element has a base body, such as a base profile 1051.

The respective sliding rollers 1052 may be mounted or placed (here approximately centered) on and rotatably supported on a corresponding number of first shafts 1053 a. The first shafts 1053a may be held at their ends in two side walls of the base profile 1051, respectively. It can then be provided that the upper circumferential edge region of the sliding roller 1052 protrudes through a window-like cutout at the upper side of the base profile 1051. On said circumferential edge region of the sliding roller 1052, the sliding fan 1 can be moved horizontally in the moved position. For this purpose, the sliding fan 1 must be lifted with the first roller element 1050 from its lowered position into an upper, displaced position.

For this reason, the vertical height position of the first roller element 1050 can be changed again vertically, so that the sliding fan 1 together with the first roller element 1050 can be moved from a vertically lower lowered position into a higher moved position relative to this lowered position relative to the jamb frame 300.

In this case, the embodiment according to fig. 9 to 11 provides that the height-adjustable first roller element 1050 itself can only be lifted and lowered vertically, but cannot be moved horizontally, which is sufficient for the height adjustment of the first roller element.

In order to change the height level of the height-adjustable first roller element 1050, a plurality, here three runner rollers 1054a, 1054b and 1054c are provided on the first roller element 1050 in addition to the sliding rollers 1052 according to fig. 9 to 11. These chute rollers are disposed on the second shaft 1053 b. The first shaft 1053a and the second shaft 1053b may be respectively disposed multiple times and respectively alternately in the sliding direction. They can be held at their ends in the side walls of the base profile 1051.

It can also be provided from fig. 9 to 11 that the sliding rollers 1052 have a larger diameter than the grooved rollers 1054a, 1054b, 1054c. Furthermore, the first shaft 1053a of the sliding roller 1052 can be held in the base profile 1051 at a position which is higher in the vertical direction than the second shafts of the chute rollers 1054a, 1054b, 1054c

The sliding rollers 1052 and the intermediate runner rollers 1054b can roll on at least one corresponding ramp profile track with the ramps 1056a, 1056b, 1056c of the runner body or runner profile 1056.

Here, the first shaft 1053a and the second shaft 1053b preferably do not move horizontally. But they can only move vertically up and down. Respective slide and/or run rollers 1052, 1054a, 1054b, 1054c are rotatably mounted thereon.

To achieve this, the first shaft 1053a and/or the second shaft 1053b and/or (as shown here) the two chute rollers 1054a, 1054c are guided along vertically oriented tracks 1331, 1332 of the bottom beam 1330, respectively. In this case, the two runner rollers 1054a, 1054c preferably have the task of rolling up and down in these tracks.

The rail may be formed by a long hole or by a slit extending vertically in the element of the bottom profile, for example in the bottom beam 1330. The rails 1331, 1332 may be designed to be upwardly open. For the construction of the rail, for example, vertical slits can be formed in the bottom beam 1330.

The chute profile 1056 is preferably configured to roll itself like a car. For this purpose, the chute profile can have one or preferably a plurality of pulleys 1058, on the underside of which the chute profile is arranged to be able to roll. In this way, the chute profile can move horizontally, in particular when the drive 57 (similar to fig. 7) is hinged to the chute profile 1056. The chute profile can thus be moved horizontally in the sliding direction of the sliding door 1 by means of the drive 57.

If the chute profile 1056 is moved horizontally in this way, it has a preferably plurality of inclined, similarly inclined, planar ramps 1056a, 1056b, 1056c, 1056d, 1056e, the ramp profile track moving horizontally under the middle chute roller 1054b and the slide roller 1052, so that one or both of these rollers roll on the ramp profile track. Since the first and second shafts held in the vertical rails 1331, 1332 of the bottom beam 1330 of the base profile can only be moved vertically, the first roller elements 1050 are adjusted here according to the respectively given ramp height, i.e. the first roller elements 1050 are lifted or lowered. The sliding roller 1052 follows this movement. In this way, the entire height-adjustable first roller element 1050 can be lifted or (in the reverse sequence of movement) lowered again in a simple manner together with the sliding fan 1.

In the raised position of the first roller element 1050, the sliding leaf 1 again moves horizontally on the sliding roller 1052 of the first roller element, which protrudes through the base profile, and moves for example onto the second roller element 60.

The rollably movable ramp profile rail with ramps 1056a, 1056b, 1056c may be constructed and arranged in the bottom beam 1330 or in a section of the bottom beam.

According to fig. 9 to 10, only a single chute profile 1056 is provided. The term "chute profile" is not to be interpreted too narrowly in this context. Chute tracks with ramps 1056a, 1056b, 1056c may also be added to the plate. This is also understood within the scope of this document as a chute profile.

The chute track preferably has a plurality (in this case, illustratively five) of ramps 1056a, 1056b, 1056c, 1056d, 1056e extending obliquely to the horizontal and obliquely to the vertical. And in other embodiments it is also provided that a recess can also be provided at the upper and/or lower position of the ramp profile rail in order to delimit one or more positions for one of the sliding rollers 1052 and/or the guide rollers.

According to the embodiment, the entire chute profile 1056 with the ramp profile track with the ramps 1056a, 1056b, 1056c is movably arranged in the guide channel 3 and can be moved with the rolling slide roller 1052 and the rolling chute roller 1054b over the first roller element 50 of variable height in order to rollingly raise and lower this first roller element 1050, preferably vertically or perpendicularly to the horizontal.

For this purpose, the ramp profile rail (as in the base profile 51 in fig. 6) can be moved by a drive 57. For this purpose, the drive can be configured, for example, as a lifting cylinder and can be articulated to the end of the base profile (not shown).

Furthermore, the sliding profile 1056 can be mounted in a rolling manner on its own pulley 1058 in the guide channel 3, so that it can be moved more easily than if it were mounted in a sliding manner.

In this embodiment, at least one second roller element 60 can also be provided, on which the sliding fan 1 can be moved horizontally with its lower rail-like running surface, wherein the second roller element can have two or more sliding rollers 52, on which the sliding fan 1 can be moved horizontally relative to the second roller element 60 (not shown here, as in fig. 1).

Thus, the ramp profile rail is also configured to be rollably movable, and it is capable of being moved over the height-variable (first) roller element 1050 by at least one or more rolling chute rollers 1054a, 1054b, 1054c and at least one or more sliding rollers 1052, so as to rollably raise and lower the first roller element 1050 as a whole.

The embodiment of fig. 9 to 11 is distinguished in particular in that the structural design is simple and the first roller element 1050 is reliably guided vertically with small tolerances in order to define and reach the lowered position and the displaced position.
