From the US 1,971,098 A is a guide known for a sliding door. The sliding door slides in a floor guide rail. For noise reduction is provided, inter alia, that on the door underside a sliding attachment is mounted, which consists of an elastic material, such as rubber, and which is provided on its the guide rail facing surfaces with metallic sliding elements.

From the JP 11-315660 A For example, there is known an upper sliding guide device for a sliding door which is mounted on the sliding door and slides therewith in a guide rail. On an upper end of the sliding door a U-profile rail is fixed. The connection of the U-profile rail with the guide rail is made via a sliding profile with a rectangular cross-section. An upper slider, which is mounted on top of the sliding profile, is guided in the guide rail. A lower sliding element, which is mounted on the underside of the sliding profile, engages in the U-profile rail.

From the US 3,168,355 A is known a vertically extendable sliding element for a sliding door.

The DE 10 2006 051 358 A1 describes a horizontally movable guided lift / slide door with a frame frame, wherein the frame frame a horizontally extending guide profile with a guide groove for guiding a guide slider and wherein the lift / slide door having an upper horizontal spar. The guide slider is provided with a base and a guide pin, wherein the base of the guide slider is rigidly secured to the upper horizontal bar of the lift / slide door and the guide pin of the guide slide horizontally and vertically slidably engages the guide groove of the guide profile. The upper horizontal leg of the lift / slide door has a metal reinforcement profile, with the guide slider bolted to the reinforcement profile. The guide pin of the guide slider has the shape of a cylinder with a diameter corresponding to the width of the guide groove of the guide profile.

The DE 20 2010 008 009 U1 describes a guide rail for guiding a sliding element, which is designed to open or close an opening in a building, with at least two strips, wherein the guide rail is arranged on a frame of the sliding element or on a Traufriegel a conservatory. Between the two strips a guide and sealing rail of the sliding door is guided. The guide and sealing rail is received in a third rail which is arranged in a groove of the sliding door.

From the EP 1 582 677 A1 a fitting for lifting / sliding wings is known, with an effective in the closed state burglary protection consisting of a operable by a handle gear for at least one vertical push rod, which is coupled via a corner drive with a first carriage, via a connecting element with a second carriage is coupled, which is connected via a second corner deflection with a vertically guided on the wing thrust element, which is associated with a thrust reversing device, via which a vertically slidably guided on the wing locking element is displaceable down into engagement with a spatially fixed engagement element.

The object of the present invention is to provide an improved upper guide a lifting / sliding door.

This object is achieved by the aforementioned lifting / sliding door, in which a third guide rail is arranged between the guide slides, wherein the third guide rail a third longitudinal extent in the direction of the second longitudinal extent of second guide rail, and wherein the third guide rail extends into the first guide rail, and is arranged distanced to the first guide rail and wherein the guide sliders are at least approximately U-shaped with two legs, wherein the third guide rail is disposed between the two legs.

The advantage here is that the upper slide of the lift / slide door is improved by the movement of a rail in a rail during the opening and closing of the lifting / sliding door by the arrangement of another guide rail, at the same time by the engagement of the third guide rail in the the first guide rail improved collapse protection is achieved compared to versions of sliding guides known from the prior art sliding guides with sliding bolts by the introduction of a burglary tool between the frame profile and the door leaf frame profile is difficult or prevented in the third guide rail.

According to a variant of the lifting / sliding door, it is provided that the longitudinal extension of the third guide profile rail amounts to at least 70% of the second longitudinal extent. It is thus further improved the burglary protection, since the third Führungsprofischiene extends at least over a majority of the longitudinal extent of the first and second guide rails, whereby the engagement of a burglary tool in these guide rails difficult or prevented.

To further improve the stability of the sliding guide can be provided that the guide slides are connected to each other via the third guide rail or the guide slides are formed by a part of the third guide rail. It is thus a higher security against "tilting" of the guide glider achieved, whereby the lifting / sliding door can be made smoother. In particular, the gap between the guide slides and the first guide rail in the frame profile can be slightly increased, whereby the friction between the guide slides and this guide rail can be reduced.

A simple assembly of the upper sliding guide of the lifting / sliding door can be achieved if the guide glides are positively connected to the third guide rail. In addition, if necessary, a simple replacement of the guide glides is possible.

The third guide profile rail may have at least one guide web, which is guided in a guide groove of the second guide rail in the door leaf frame profile. In support of the leadership on the guide gliders an additional guidance of the lifting / sliding door is thus indirectly achieved by the third guide rail is more integrated into the second guide rail and thus more resilient in terms of tilting.

Likewise, it is advantageous with regard to a better guidance and a higher mechanical load capacity if the guide slides each have at least one guide web which is guided in a guide groove of the second guide profile rail.

To reduce frictional forces during the sliding movement of the lifting / sliding door, provision is made for the third guide rail to be arranged at a distance from the first guide rail so that the third guide rail does not come into contact with the first guide rail during the sliding movement.

It is further provided that the guide sliders are formed at least approximately U-shaped with two legs, wherein the third guide rail is disposed between the two legs. On the one hand, a better integration of the third guide rail in their end areas in the overall system "sliding" is achieved. On the other hand, but also the assembly of the third guide rail with the guide slides is achieved by the latter these components can be easily assembled. Especially the latter is in view of the advantage that the guide is usually assembled only on the site.

In order to avoid a relative movement between the guide slides and the second guide profile rail, it is advantageous if the guide slides are secured against displacement in the longitudinal extent of the second guide rail with at least one securing element. It is therefore not necessary to fix the guide gliders even in the correct exact position on the lifting / sliding door, which in turn simplifies the assembly of the sliding guide.

According to a preferred embodiment, it is provided that the securing element is formed by a cover which covers an end face of the second guide rail and which extends partially into the second guide rail. It is thus achieved a reduction of the individual components of the sliding guide by this component takes over several functions. In addition, so that the guide slide with the third guide rail for maintenance work more accessible by merely this cover must be removed that is usually attached to the vertical door leaf frame profiles.

It is advantageous if the cover is provided with a sealing element, whereby the slide can be better protected from moisture penetration. It can thus be prevented squeaking noise during operation of the lifting / sliding door, which can occur when wet plastic surfaces slide together.

But it is also possible to form the securing element as a simple stop buffer, so that a mechanical connection of the securing element to the guide slider or the third guide rail is not required.

It is advantageous if the stop buffer extends into the second guide rail or is arranged in this, since this simplifies the arrangement of grooves in the vertical door leaf frame profiles for the arrangement of locking fittings.

For a better understanding of the invention, this will be explained in more detail with reference to the following figures.

Also, the location information chosen in the description, such as top, bottom, side, etc. related to the immediately described and illustrated figure and are to be transferred to the new situation mutatis mutandis when a change in position.

The Fig. 1 to 4 show a variant of a lifting / sliding door 1. This has a door 2 and a fixed glazing 3, ie a fixed glass element, as is known per se. Such lifting / sliding doors 1 are used for example in conservatories or in the area of terraces and balconies. Of course, other uses are given.

The lifting / sliding door 1 has a frame 4, which is fastened for example in a wall opening. The window frame 4 comprises an upper horizontal window frame profile 5. This has a door frame 2 facing lower frame bottom 6. In this Blendrahmenprofilunterseite 6 a Blendrahmenprofilnut 7 is formed in which a first guide rail 8 is arranged and fixed, for example screwed to the frame and / or glued to it. The Blendrahmenprofilnut 7 extends - viewed in terms of their cross-section - away from the Blendrahmenprofilunterseite 6 in the direction of the door 2 and has a longitudinal extent in the direction of the longitudinal extent of the upper horizontal frame profile 5.

The first guide rail 8 has a first longitudinal extent 9, wherein this first guide rail 8 generally extends from a first vertical window frame profile 10 to a second vertical window frame profile 11, so that the door leaf 2 can be completely opened.

The door leaf 2 has a door leaf frame 12, which comprises an upper horizontal door leaf frame profile 13. The upper horizontal door leaf frame profile 13 has a door leaf profile top 14 facing the upper horizontal window frame profile 5. In this door leaf profile top 14 a Türflügelprofilnut 15 is arranged, which - viewed in terms of their cross-section - from the door leaf profile top 14 in the direction of a glass element 16 which is held by the door leaf frame 12 extends. The door leaf profile groove 14 has a longitudinal extent in the direction of the longitudinal extent of the upper horizontal door leaf frame profile 13. In this door leaf profile groove 15, a second guide rail 17 is arranged, which has a second longitudinal extent 18 in the direction of the first longitudinal extent 9 of the first guide rail 8. The second guide rail 17 in particular has a length which at least approximately corresponds to the length of the upper horizontal door leaf frame profile 13 in this area.

In this second guide rail 17 guide slide 19 are arranged. In particular, a respective guide slide 19 is arranged in each case in one end region 20, 21 of the second guide profile rail 17, wherein the two end regions 20, 21 are formed opposite one another in the direction of the second longitudinal extension 18 of the second guide profile rails 17.

The guide slide 19 have a height 22 which is dimensioned so that the guide slide 19 on the one hand with the door still engaged in the first guide rail 8 of the frame profile 5 and on the other hand, the lifting of the lifting / sliding door 1 is not hindered when opening, so the first Guide rail 8 in the direction of a base 22 which extends between two legs 23, 24, still enough travel for the lifting of the guide slide 19 when opening the lifting / sliding door 1 is present.

The frame 2 and / or the door leaf frame 12 may be made of wood and / or plastic and / or a metallic material. In the variant wood the Blendrahmenprofilnut 7 and the Türflügelprofilnut 15 are prepared for example by milling. In the other two variants, they can already be formed during the production of the corresponding profiles.

The first and / or the second guide rail (s) 8, 17 may at least partially consist of a metallic material, for example of aluminum or an aluminum alloy, or of plastic, for example PVC, PA6 or POM. In particular, self-lubricating plastics are used.

The guide slide 19 may also at least partially made of a metallic material, such as a sintered metal, or plastic, such as PTFE, PA6 or a self-lubricating plastic, such as POM, or other plastic, in mating with the material of the first guide rail 8 a low coefficient of friction, exist. Optionally, the guide sliders 19 may have a coating which, in mating with the material of the first guide rail 8, has a low coefficient of friction, for example a lubricating varnish. This coating is applied at least in that area in which the guide slides 19 slide on the first guide rail 8. It is also possible for a composite material made of a first plastic and a second plastic to be used at least in that region in which the guide slides 19 slide on the first guide profile rail 8 and which has a low coefficient of friction. Conversely, it is possible that the first guide rail 8 at least in those areas in which slide the guide slides 19 are coated with such a plastic with a low coefficient of friction or formed from this.

On the frame 2 and / or on the door leaf frame 12, at least one seal 25, 26 can be arranged or formed from the elastomeric materials customary for this purpose. The representation in Fig. 2 is not meant to be limiting in this regard.

It is also possible that 12 metallic attachment shells 27, 28 are arranged or attached to the frame 2 and / or the door frame, for example, made of aluminum or an aluminum alloy.

In addition, 12 thermally insulated profile elements can be used for the frame 2 and / or the door leaf frame, for example, at least partially filled with a foam hollow chamber profiles made of plastic. The thermal insulation may optionally also be arranged between the profile elements and the attachment shells 27, 28.

The Blendrahmenprofilnut 7 and / or the Türflügelprofilnut 15 have a rectangular cross-section. Likewise, the first guide rail 8 has a rectangular cross-section. Optionally, these first guide rail 8 may be provided in the region of the open ends of the legs 23, 24 with bends, as shown, so that the Blendrahmenprofilnut 7 can be better covered. These bends can also be arranged sunk, so that they connect flush to the frame profile lower side 6.

Also, the second guide rail 17 has a rectangular or square outer cross-sectional shape, so that it preferably rests against the side walls of the door leaf profile groove 15. As in Fig. 2 shown is also the first guide rail 8 on the side walls of the Blendrahmenprofilnut 7.

But it is also possible to provide other cross-sectional shapes for the door leaf profile groove 15 and / or the Blendrahmenprofilnut 7. The guide profile rails 8, 17 have a corresponding, corresponding outer cross-section. For example, it may be provided that the door leaf profile groove 15 and / or the frame profile groove 7 have or have at least one transverse groove 29 into which a corresponding outer transverse web 30 of the guide profile rails 8 or 17 engages, in particular positively, as in Fig. 2 is shown in dashed lines. Also Schwalbenschanzausführungen are possible.

Between the guide sliders 19, a third guide rail 31 is arranged, which has a third longitudinal extent 32 in the direction of the second longitudinal extension 18 of the second guide rail 17. The third guide rail 31, has a height 33 which is dimensioned so that it extends into the first guide rail 8.

The third guide profile rail 31 preferably consists of a metallic material, in particular of aluminum or of an aluminum alloy. But it is also possible to use as a material for the third guide rail 31, a plastic, such as a fiber-reinforced plastic, in particular reinforced with glass fibers.

In the preferred embodiment, the third guide rail 31 has an at least approximately T-shaped cross-section, wherein it is installed with respect to its cross-section upside down, so that therefore forms the crossbar of the T, so a base 34, from which a vertical leg 35 extends in the direction of the first guide rail 8.

Although this cross-sectional shape is the preferred, other cross-sectional configurations for the third guide rail 31 are possible.

The length of the third guide profile rail 31 in the direction of its longitudinal extension 32 may preferably amount to at least 70% of the second longitudinal extension 18 of the second guide profile rail 17. In principle, however, shorter versions are possible, although this may be accompanied by a reduction of burglary protection (depending on the length of the guide slide 19), as thus areas between the guide slides 19 and the third guide rail 31 remain open and thus can provide a point of attack for burglary , Nevertheless, these variants offer a better burglary protection compared to known from the prior art lifting / sliding doors.

The length of the third guide profile rail 31 in the direction of its longitudinal extension 32 is particularly preferably at least 80%, in particular at least 90%, of the second longitudinal extension 18 of the second guide profile rail 17.

As will be explained in more detail below, the length of the third guide profile rail 31 in the direction of its longitudinal extension 32 is preferably dimensioned such that the third guide profile rail 31 extends together with the guide slides at least approximately over the entire length of the second guide profile rail 17 in the same direction. The expression "at least approximately" will be explained below, but at least also means that the third guide profile rail 31 may have the same length as the second guide profile rail 17.

The guide slides 19 are connected to each other via the third guide rail 31. For this purpose, the guide slides 19 have an at least approximately U-shaped cross-section - viewed in plan view in the installed position - with two legs 36, 37 and a base 38, as shown in particular in FIGS 3 and 4 is apparent. The base 38 is oriented in the installed position of the guide slide 19 in the direction of the respective end face of the door leaf frame profile 13. The third guide rail 31 is arranged with its end regions between the two legs 36, 37. Thus, the guide sliders 19 at the same time form closure elements for the third guide rail 31.

But it is also possible that the guide slide 19 are formed by a part of the third guide rail 31, so are formed integrally with the third guide rail 31. In this case, the third guide rail 32 may have projecting areas in the direction of its longitudinal extension 32, preferably on both sides, so that the third guide rail only reaches the leading guide rail 8 in the window frame profile 5 via these areas. These projecting regions can also be provided with a lubricious coating, for example a lubricious coating. In particular, these projecting portions are formed in the end portions of the third guide rail 31. These may consist of the material of the third guide profile rail 31 itself or a material different therefrom, for example by molding this area on the third guide profile rail 31.

But it is also possible that the third guide rail does not extend into the guide slide 19, but, for example, butts against it bluntly.

In principle, however, it is also possible, as has already been stated, for the third guide profile rail 31 to be arranged at a distance from the guide slides 19.

The preferred connection of the guide slide 19 to the third guide rail 31 also has the advantage that, if necessary, no separate attachment of the third guide rail 31 in the second guide rail 17 is required. In addition, so that the third guide rail 31 can be arranged in a simple manner distant from the first guide rail 8 in order to reduce the adjacent sliding surfaces and thus also the friction. The distance of the surfaces of the third guide rail 17 from the respective opposite side wall of the first guide rail can be made small, for example, be between 4 mm and 8 mm.

It is further possible to dispense with the base 38 of the guide slide 19, so that the guide slides 19 are formed only by the legs 36, 37, in which case a total of four guide slides 19, two per end region of the third guide rail 31, preferably opposite each other, be arranged on the third guide rail 31 and preferably connected to this.

In principle, other embodiments of the guide slide 19 are possible, for example, by being arranged on the upper, on the first guide rail 8 in the frame profile 5 facing end face, in particular in a recess in this end face.

According to a development of the connection of the guide slide 19 to the third guide rail 31 can be provided that the guide slide 19 are positively connected to the third guide rail 31. For this purpose, the third guide rail at least one connecting web 39, for example four connecting webs 39 to 42, as shown in Fig.2 is shown. It should be noted that the illustrated number of connecting webs 39 to 42 is not limiting.

The connecting webs 39 to 42 extend perpendicular to the longitudinal extension 32 of the third guide rail 31 and are in connecting grooves 43 to 46, in the guide slides 19 in the same direction extending to the inner, the third guide rail 31 facing surfaces are formed, added. Advantageously, the connecting grooves 43 to 46 have a dovetail-shaped cross-section, wherein other cross-sectional shapes, for example rectangular or square, etc., are possible. The connecting webs 39 to 42 accordingly have a corresponding cross-section.

But it is also the reverse design possible, so the arrangement of the connecting webs 39 to 42 to the guide slides 19 and the arrangement of the connecting grooves in the third guide rail 31st

For connecting the third guide rail 31 to the second guide rail 17, the third guide rail 31 may have at least one guide web, which is guided in at least one guide groove 47, 48 of the second guide rail 17 in the door leaf frame profile 13. In particular, two such guide webs are formed opposite each other and these guide webs are preferably formed by the base 34 of the T-shaped cross-section of the third guide rail 31.

However, other connections of the third guide rail 31 to the door leaf frame profile 13, in particular the second guide rail 17 are possible. For example, the third guide rail 31 can be screwed, riveted or glued to the second guide rail 17.

To improve the mechanical connection of the guide 19 without expensive connection methods, such as screw, rivet or glue, and thus for better connection of the third guide rail 31 to the second guide rail 17, it is advantageous if the guide slide 19 each at least one guide web 49th , 50, it can also be more than ever one of the guide webs 49, 50 are present, which are each guided in a guide groove 51, 52 of the second guide rail 17. The two guide webs 49, 50 are arranged opposite one another on the legs 35, 36 of the guide slide 19 and extending away in the direction of the third guide rail 31, as is apparent from Fig. 2 is apparent. If the guide slides 19 are not formed in one piece but as plate-shaped elements without the base 34, this embodiment variant is also possible.

In particular, the two guide webs 49, 50 of the guide slide 19 may be arranged at least approximately at the height of the two connecting webs 39, 41 of the third guide rail 31, but also a staggered training is possible.

To simplify the mounting of the upper guide system of the lifting / sliding door 1, it is preferred that the guide slides 19 and the third guide profile rail 31 are not connected to the second guide rail 17 via screw connections, etc., but that the guide slides 19 are prevented from shifting in the longitudinal direction 18 the second guide rail 17 are secured with at least one securing element 53. After so that the guide slide 19 are connected in particular positively, preferably via the above-described profile elements with at least approximately U-shaped cross-section, and after the guide slide 19 are at least partially terminally arranged on the third guide rail 31 in the preferred embodiment, wherein the end faces of the third Guide rail 31 preferably each abut the base 34 of the guide slide 19, so that at the same time the third guide rail 31 is avoided against displacement in the second guide rail 17 in the direction of the longitudinal extension 18.

Two such securing elements 53 are in the 3 and 4 shown, wherein in the preferred embodiment of the lifting / sliding door 1 both embodiments are used, namely the first embodiment on the one end side of the second guide rail 17 and the second embodiment on the second, the first along the second guide rail 17 opposite end face.

It should be noted, however, that the illustrated embodiments of the fuse element 53 are the preferred, but other embodiments with the same effect are possible.

In the first embodiment of the fuse element according to Fig. 3 the securing element 53 is designed as a push-in element for insertion into the second guide rail 17 and forms at least during the assembly of the guide system a stop buffer 54 for the respective guide slide 19 and the third guide rail 31. For this purpose, the guide slide 19 and the third guide rail 31 facing face 55 be executed increased, ie a plug-in body 56 in terms of height outstanding, as in Fig. 3 is shown.

The insertion body 56 in turn is inserted into the second guide rail 17, so that this nachformt the contour of the second guide rail 17 in the lower region, in particular in the guide grooves 47, 48 of the second guide rail 17 with corresponding guide webs 57, 58 engages. Thus, therefore, the stop buffer 54 also have an approximately T-shaped cross section, wherein the crossbar of the T, the two guide webs 57, 58 can form.

This embodiment of the stop buffer 54 has the advantage that its insertion body 56 can be formed relatively flat, whereby a screwing of the stop buffer 54 with the second guide rail 17 and / or the door leaf frame profile 13 is simplified. However, there are also higher embodiments of the stop buffer possible, preferably the stop buffer, the second guide rail 17 does not exceed the height, although this is possible and in this case, the stop buffer also contribute to the leadership in the first guide rail 8 in the frame profile 5.

It should be noted that the second guide rail 17 may be bolted to the door leaf frame profile 13. Likewise, other compounds, such as a bond, etc. possible.

Preferably, the stop buffer 54 is mounted on the lock side, ie on that side of the door leaf 2, on which the locking fitting is mounted. In Fig. 1 this is the left side of the door leaf 2. The locking lock or the locking fitting is preferably installed in a groove 59 and arranged in this at least partially. Due to the arrangement of the stop buffer 54 in the second guide rail 17, which ends preferably flush with the second guide rail 17 and a groove bottom 60 of the groove 59, the guide slider 19 and thus the third guide rail 31 and in the embodiment of the third guide rail 31 with plate-shaped guide slides 19, the third guide rail 31 spaced from the groove base 60 is arranged. As a result, the installation of the locking lock or the locking fitting is simplified.

In principle, however, it is also possible, in particular if no locking lock or locking fitting is arranged, for the guide slide 19 or the third guide profile rail 31 to extend at least approximately as far as the end face of the door leaf frame profile 13.

The stop buffer 54 is in particular made of a plastic, for example of an elastomer such as EPDM, TPE, or another plastic, such. PA6, or a fiber-reinforced plastic, in particular reinforced with glass fibers, but can also be made of a metallic material.

In Fig. 4 a further embodiment of the securing element 53 is shown. This is formed by a cover 61 or has a cover. This cover member covers an end face 62 of the second guide rail 17 from. In the preferred embodiment, an insertion element 63 is arranged on the cover, in particular integrally formed therewith. This insertion element 63 extends at least partially into the second guide rail 17. The insertion element 63 may for this purpose have a cross section which corresponds at least approximately to the cross section of the stop buffer 54, although the above increased end face 55 of the stop buffer 54 in the insertion element 63 is not necessarily present got to.

An embodiment is also possible in which the securing element 53 has only the cover element 61 without the insertion element 63, in which case the guide slide 19 or the third guide profile rail 31 can extend up to the cover element 61 on the inside, ie not at a distance from one another Covering 61 is arranged.

The cover 61 may extend only in the region of the second guide rail 17 to the frontal cover. Preferably, however, the cover member 61 extends over a larger area as shown in FIG Fig. 4 is shown. In particular, the cover 61 may be formed projecting beyond a side surface 64 of the vertical door leaf frame profile. In this case, it is advantageous if the cover is provided with a sealing element 65 for lateral sealing of the door leaf frame 12. The sealing element 65 may for example consist of a foam, an elastomer such as TPE, EPDM, Rubber, etc., exist and can be arranged extending perpendicular to the cover 61.

The cover 61 is in particular made of a metallic material, but can also be made of a plastic, such as PA6.

The insertion element 63 consists in particular of a metallic material, but can also be made of a plastic, for example PA6.

In the preferred embodiment, the upper guide system of the lift / slide door 1 is mounted as follows.

In a first step, the first guide rail 8 and the second guide rail 17 are arranged in the corresponding grooves in the frame profile 5 or in the door leaf frame profile 13 mounted in, for example screwed. Thereafter, the stop buffer 54 is mounted in the second guide rail 1. Then, the first guide slide 19 is inserted into the second guide rail 17 in the corresponding guide grooves 51, 52 and then pushed to the stop buffer 54, then the third guide rail 31 is inserted into the guide grooves 47, 48 and advancing pushed into the guide slider 19. Subsequently, the second guide slider 19 as the first inserted into the second guide rail and moved until the third guide rail 31 is present on the inside 38 of the base.
