Description

The invention relates to a system and the use of a system for connecting a joint area between two laterally vertical frame members, also known as frames, of a frame to be used in a building opening and a lower threshold profile, which is also referred to as a ground threshold, in particular for a sliding sash, folding Sliding sash or slidable lifting and sliding sash of a window or door according to the preamble of claim 1.

Sliding sashes as sliding sashes, folding sliding sashes or movable lifting and sliding sashes of a window or door are known in a wide variety of designs and consist in the simplest case of a sliding sash arranged in an outer frame for opening and closing and of a sash, also in the frame arranged additional door or window element, such as fixed leaf or fixed panel.

The closed sliding sash can be locked on its side facing away from the door or window element by actuating a fitting provided in the sash frame and thus secured against unauthorized opening. Horizontally movable sashes are usually slidably received above or below the sash. When opening, usually with an actuating handle of lifting and sliding sashes, the sliding sash is lifted with the seals, making it easier to run. The open sliding leaf can then be pushed in front of an adjacent passive leaf. Depending on the design, lift-and-slide sashes can only be pushed or additionally tilted. When closing, the sliding sash is lowered and the seals are pressed on again. Opening and closing is also possible via electric, hydraulic or pneumatic actuators.

Sealing problems have become known in the lower joint area between two laterally vertical blind frame members or frames of a blind frame to be used in a building opening and a lower threshold profile, which is also referred to as a ground threshold. The water is then pushed by the wind into the connection area below the vertical window frame bars of the window frame and the horizontal threshold, so that the water can not only penetrate into the threshold area, but also transversely into the masonry via capillary joints running lengthwise. A large number of different components and materials are used in a very small space to close gaps and to connect the window frame bars to the threshold profile or the threshold, which are sealed with a sealing compound, for example made of a liquid plastic. A permanent connection of the materials and adhesion of the sealant are not ideal. The optics and assembly are also neglected with regard to the known prior art.

Furthermore, the joint areas of the respective vertical beams and horizontal beams or threshold profile/threshold necessarily belong to the connection of two components.

In principle, two different methods for connecting post profiles with such threshold profiles are used in the prior art. With the first method, the face of the post profile is milled so that it corresponds exactly to the surface contour of the threshold profile. In the second method, the face of the post profile is usually cut to length or separated vertically and connected to the sleeper profile using a sleeper holder or sleeper connector, with the sleeper connector compensating for the uneven surface contour of the sleeper at least in some areas. The invention relates to a system of the last-mentioned type.

From the EP 3 025 003 B1 a system with a post profile, a threshold and a threshold holder, also known as a threshold connector, has become known. The threshold has a channel designed as an undercut, with the post profile forming, in particular, a T-shaped or L-shaped cross section. The sleeper holders serve to connect the post profile, in particular a setting post with a T-shaped cross section or a post with an L-shaped cross section, to a sleeper profile, the sleeper profile having a non-planar surface. The threshold used has an inside step surface, an outside step surface that is lower than the inside step surface, and the channel designed as an undercut between the inside and outside step surfaces.

According to the known design, a connection between the threshold and the threshold holder is made possible by means of screws. The joining of the post profile to the threshold is shown. Joint areas occurring between the threshold and the post profile are neglected in the case of the object with regard to tightness. In particular, leaks occur at the joint areas on the outside or the weather side. These are unprotected and exposed to the direct influence of the climate.

The invention is based on the object of providing a functionally reliable and compact system To provide a window or a door, in particular a sliding sash, folding sliding sash or movable lifting and sliding sash, which eliminates the above disadvantages and is inexpensive with good optics for the window or door and in a simple, fast, safe and precise manner with little space can be mounted and adjusted in a sealed manner.

According to the invention, the object is achieved by a system according to claim 1 and by the use of such a system according to claim 11. Advantageous refinements of the invention result from the features of the dependent claims.

For sealing closure and for easy installation, in particular of the critical area below the window frame spar in the transition to the threshold profile/threshold, it is proposed according to the invention that at the lower end of the window frame spar of the window or door, in particular for a sliding sash, folding sliding sash or lifting/sliding sash, to place a sealing pad. The sealing pad is arranged between the threshold profile and the outer frame member during the connecting assembly of the threshold profile and the outer frame member and is compressed by means of an assembly mandrel in such a way that it protects the window or door from possible climatic influences, with regard to thermal expansion or, for example, driving rain with the desired tightness .

For this purpose, the sill profile, the window frame bar and a sill connector. The threshold profile is designed with an inside step surface and a sunken outside step surface, with the threshold connector having a bottom side and a top side, with the top surface terminating flush with the inside step surface. The flexible sealing pads can preferably be placed on the upper side of the threshold connector and the inner tread surface in an overlapping position, which together form a flush plane.

For this purpose, the sealing pad is designed to be flexible, which consists, for example, of flexible plastic, for example TPE. Alternatively, however, a sealing pad made of foam rubber or a similar material that is glued on or applied in some other way can advantageously be used. An open-cell foam layer is used in a particularly advantageous manner, particularly preferably a foam rubber sealing pad that covers the upper side of the threshold profile and the threshold connector. Other flexible, sealing materials are also possible.

For further advantageous assembly, at least one connecting element is placed on the flush level of the sealing pad and fastened with screws from the underside of the threshold profile in a force-fitting manner. Furthermore, the cross-section of the blind frame member has hollow chambers into which the connecting element is inserted in a form-fitting manner. In this way, the window frame beam automatically receives a stable and upright preset position for a final assembly connection, sitting on the threshold profile with the sealing pad coming into contact. The blind frame member and the connecting element have corresponding recesses for receiving an assembly mandrel. The final assembly connection for a firm and tight fit is achieved by inserting and twisting the assembly mandrel into the corresponding recesses of the outer frame spar and the connecting element, with the outer frame spar being forced and pressed onto the soft elastic sealing pad of the threshold profile.

In a further development of the invention, the recesses on the opposite side of the wing of the rear side of the vertical frame spar are preferably formed as a bore and consist of a slot transverse to the longitudinal direction of the frame spar in the connecting element. By rotating the assembly mandrel using a tool, the assembly mandrel is twisted in the hole and at the same time displaced in the slot due to its eccentricity, which causes the frame member to be increasingly tightened and pressure to build up on the sealing pad and thus the threshold profile.

For this purpose, preferably two connecting elements are placed on the threshold profile, divided in the depth of the window or door, and inserted into hollow chambers of the window frame spar that are spaced apart independently of one another. Thus, in an advantageously simple manner, a bridge that can be connected is created between the threshold profile, the threshold connector and the outer frame member with a stable form-fitting fit of the outer frame member to the threshold profile and threshold connector.

In a further development of the invention, the assembly mandrel forms a head which has a tool engagement for the tool for rotatable adjustment on a first visible head side, ie when mounted in the frame spar and directed away from the frame spar visible free side. The tool engagement is preferably a hexagon socket. Other tool interventions are also possible.

A simple, inexpensive production and the guarantee of functionality at a rotary to achieve a sealing connection of the system for a corner connection from the threshold profile and threshold connector to the outer frame spar through the sealing pad is achieved by the fact that the assembly arbor has a first round attachment on a second head side of the head that rests in the assembled state on the back side of the outer frame spar , the axis of which runs concentrically with the head, and has a second round shoulder which is offset from the first axis of the first shoulder at a distance from a second axis and has a reduced diameter relative to the first shoulder. The eccentrically offset lugs enable a positively controlled vertical adjustment of the window frame member towards the threshold profile, which, depending on the direction of rotation of the assembly mandrel, causes the compression of the component connection or also enables loosening with a separation of the two components.

In order to achieve the above type of assembly and the advantages described below, as well as a secure and almost play-free hold, the first attachment of the assembly mandrel is adapted to the diameter of the bore on the back of the window frame spar and the second attachment is adapted to the oblong hole arranged transversely to the longitudinal direction of the connecting element recorded as a leader.

The assembly mandrel proves to be simple to manufacture and suitable for assembly in that the outer contour of the head is rectangular in shape and two of the four corners on the outer contour are directed diagonally towards one another, have roundings or bevels. The thickness of the head of the assembly mandrel is adapted to the webs on the back of the frame spar.

For a firm and secure hold, as well as for an end stop of the assembly mandrel seated on the rear side of the window frame spar, the webs running perpendicular to the threshold profile on the rear side of the window frame spar are also formed, which preferably have L-shaped undercuts in cross section. When the assembly mandrel is turned, the head of the assembly mandrel grips at least one web with its circumferential outer contour and strikes flush with the wall or edge of the web with a short side and assumes a secure end position, which at the same time represents the end position of the assembly of the corner connection system.

Such an assembly connection ensures a simple component in line with market requirements with the assembly mandrel in the basic shape of the head as a cuboid and in a material thickness that is kept flat for simple assembly. The extensive design of the head of the assembly mandrel in adaptation to the webs of the window frame spar at the transitions of the threshold profile with the threshold connector and the sealing pad enables the window or door with the system for a corner connection to have a clear, seamless shape and optimal tightness.

Depending on a functionally reliable attachment between the threshold profile with the connecting elements connected to it to form a one-piece component with a non-positive connection to the frame spar, the axis distance of the bore in the frame spar on the back side of the frame spar to the edge or wall of the undercut web is adapted to the distance of the axis of the first approach up to the short side of the outer contour of the head of the assembly mandrel. This design makes it possible for the mounting mandrels to be used in any area of the rear of the window frame member while adhering to the above dimensions and, after rotating the indicated direction of rotation by means of an arrow on the head of the mounting mandrel, beyond a 90° angle in the opposite direction Support twisting in the undercut area on the edge of the web.

Finally, it can also be advantageous if the areas of the corners with the roundings or bevels of the head of the assembly mandrel are wedge-shaped in thickness, so that they can become wedged in the undercut web in the axial direction when rotating about the axis and/or or enable safe screwing into the undercut bar.

Insofar as the threshold profile used according to the invention is to be used as a post profile for mounting a window frame spar to be connected to the end of the sill, the window frame spar is preferably cut off at right angles to the required size. Furthermore, for the sake of simplicity, a threshold connector can be connected to the threshold profile by screwing it onto a lowered outer tread surface of the threshold profile, so that a flush level is formed with a second upper side of the outer contour of the threshold connector and the threshold profile, which allows a sealing pad to be placed on the flush level of the sill profile and the sill connector in a position in which at least the cross-sectional area of the frame member is completely covered with a positive and/or non-positive fit. At the same time, the abutting edges of the threshold profile and the threshold connector are covered. Furthermore, at least one connecting element is placed, in this exemplary embodiment with two connecting elements on the threshold profile, which form a non-positive connection with the threshold profile by means of screws from the underside. Next, the vertical window frame bar is placed on the sealing pad. This is done by positively plugging the hollow chambers arranged on the window frame beam into the complementary matching connecting elements. The resulting form-fitting connection causes a corresponding hold and upright seating of the window frame spar to the threshold profile and the threshold connector even before the final assembly process. For a sealing effect, the window frame bar is then pressed against the threshold profile and the threshold connector. Inserting assembly mandrels according to the invention into the corresponding recesses on the window frame spar and in the connecting element and then turning the assembly mandrels in a direction indicated by an arrow on the head, in the lugs, causes a positively controlled tightening of the window frame spar with a compressing effect on the sealing pad. In order to permanently fix the tightened end position of the component connection, fastening screws are screwed through the spar from the rear side of the vertical window frame spar in a simple manner, which also traverse the connecting elements. Due to the fact that the threshold profile is firmly connected to one another with the connecting elements, this creates a non-positively mounted end position of the system. Due to the force-fit connection of the corner connection system, the form-fit connection of the assembly mandrels is now unnecessary. Finally, the assembly mandrels can be removed from the joined position in the window frame member and in the connecting elements by turning them in the opposite direction away from the web.

The following explanations of the system according to the invention refer, by way of example, to a window or a door 40 with a displaceable lifting/sliding sash 41, which can also be designed as a sliding sash or as a folding/sliding sash. Turn-only or turn-tilt sashes that can be equipped with such a system are also conceivable. In the selected embodiment after 1 is a basic structure of a window or a door 40 with a lift-and-slide sash 41, which is shown schematically. The window or door 40 comprises an outer frame 42 to be inserted into a building opening, which is made up of two lateral frame bars 2, 2', also known as frames, an upper frame bar 43 and a lower threshold profile 1, which is also known as a floor threshold . Furthermore, a stationary leaf 44 and the sliding leaf as a lifting and sliding leaf 41, the stationary leaf 44 and the lifting and sliding leaf 41 being inserted into the frame 42. A glazing is used in the sash frame and fixed sash frame of the lift-and-slide sash 41 or fixed sash 44.

When the lift-and-slide sash 41 of the window or door 40 is closed, the lift-and-slide sash 41 is in front of the lateral frame member 2 of the frame 42.

In other embodiments of a window or a door 40, two or more lift-and-slide sashes 41 can be inserted into the window frame 42. In order to ensure that the lift-and-slide leaf 41 can be moved in relation to the frame 42 and the fixed leaf 44, the lift-and-slide leaf 41 and the fixed leaf 44 are in two different parallel planes in the depth of the window frame 42 and the window frame bars 2, 2'. arranged. in the in 1 In the embodiment shown, the lift-and-slide leaf 41 is arranged in a plane closer to the inside of the building than the fixed leaf 44. The lower sash frame spar 45 of the lift-and-slide leaf 41 has a carriage 46 with rollers (schematically shown) on each of its two lateral ends which is slidably guided by the lifting and sliding panel 41 on a running rail, not shown, on the lower threshold profile 1 or the threshold of the window frame 42 . Guide elements (not shown) are likewise arranged on the upper wing frame spar 47 . In addition, a non-illustrated lift-and-slide fitting is attached to the sash frame of the lift-and-slide leaf 41, through which the lift-and-slide leaf 41 can be raised or lowered in the vertical direction for opening and closing and also locked.

For the sealing closure of the critical area of the window or the door 40 below the window frame spar 2, 2' in the transition to the threshold profile 1 1 , is after 3 until 5 a sealing pad 8 is arranged at the lower end of the window frame spar 2, 2'. The sealing pad 8 is arranged between the threshold profile 1 and the frame spar 2, 2' during the connecting assembly of the sill profile 1 and the frame spar 2, 2' and is positioned by means of an assembly mandrel 16 7 compressed.

To 1 has the threshold profile 1, a window frame spar 2, 2' and a threshold connector 3. The threshold profile 1 is after 2 formed with an inside tread surface 4 and a lowered outside tread surface 5 . By placing the underside 6 of the threshold connector 3 on the threshold profile 1, the top 7 of the threshold connector 3 forms 2 with the inside tread 4 a flush level 9. The threshold connector 3 is after 2 connected in a non-positive manner to the threshold profile 1 by means of fastening screws 34 . An adhesive connection is also conceivable. For a sealed connection, after 3 on top 7 of threshold connector 3 and inner tread surface 4, the flexible sealing pads 8 are placed in an overlapping position, which forms a flush plane 9 and completely covers the transition between threshold connector 3 and tread surface 4 of threshold profile 1. Webs 35 on the threshold connector 3 pointing towards the sealing pad 8 and recesses 36 formed on the sealing pad 8 ensure automatic adjustment of the sealing pad 8 on the threshold profile 1 and the threshold connector 3 by joining. A possible misalignment or undesired displacement of the sealing pad 8 is thus avoided . For a sealing connection of the system according to the invention between the transitions of the horizontal threshold profile 1 and the vertical window frame spar 2, 2', the sealing pad 8 is to be made of a material which is flexible in order to achieve compression of the material. For example, flexible plastic, which consists of TPE, for example, is suitable for such a use. In addition, a sealing pad 8 made of foam rubber or similar material that is glued on or applied in some other way can provide the necessary bring about success. Furthermore, an open-cell foam layer, particularly preferably a foam rubber sealing pad 8, can also be used.

Next will be after 4 two connecting elements 10 are placed on the flush plane 9 of the sealing pad 8 and fastened by means of screws 11 from the underside 12 of the threshold profile 1 with the threshold profile 1, the threshold connector 3 and the sealing pad 8 in a non-positive manner. Depending on the depth T of the threshold profile 1 and the frame member 2, 2', a connecting element 10 can also be used. Due to the depth T after 4 , preferably two connecting elements 10 are installed. Functionally coordinated in the length and in the cross section of the connecting elements 10, the connecting elements 10 after 5 and 6 introduced in a form-fitting manner into corresponding hollow chambers 13 of the frame member 2, 2'. In this way, the window frame beam 2, 2' is automatically seated on the threshold profile 1 with the sealing pad 8 coming into contact with a stable and upright position for a preset final assembly connection. The blind frame member 2, 2' and the connecting element 10 have corresponding recesses 14, 15 for a final assembly position. A firm and sealing seat is achieved by inserting and twisting an assembly mandrel 16 into the respective corresponding recesses 14, 15 of the window frame spar 2, 2' and the connecting element 10 8th until 10 .

In a further development of the invention, the recesses 14, 15 are formed as bores 17 on the rear side 18 of the frame spar 2, 2' and transversely to the longitudinal direction of the frame spar 2,2' in the connecting elements 10 as a slot 19. To insert the mounting mandrels 16 into the recesses 14, 15, they are first in the position according to 9 brought and inserted into the recesses 14, 15.

By rotating the assembly mandrels 16 via a tool, not shown, in the tool engagement 22 10 until 12 and 13 until 15 , the assembly mandrels 16 in the bore 17 to the position after 15 right assembly mandrel 16 twisted and displaced by its eccentricity between the projections 24, 26 in the slot 19, which causes an increasing tightening and pressure build-up of the window frame spar 2, 2' on the sealing pad 8 and thus the threshold profile 1.

In this embodiment, after 4 on the threshold profile 1 divided in the depth T two connecting elements 10 placed and in independently distant hollow chambers 13 of the frame member 2, 2 'used. In the tightened position 11 A one-piece unit is created between the threshold profile 1 and the window frame spar 2, 2' with a stable form-fitting fit of the window frame spar 2, 2' to the threshold profile 1.

The head 20 of the assembly mandrel 16 has a simplified rotary movement 7 a first visible head side 21, which forms the tool engagement 22 for the tool for rotatable adjustment and indicates the direction of rotation with an arrow. In this embodiment, the tool engagement 22 is designed for a hexagon socket. Other tool interventions are also conceivable.

On the second head side 23 of the assembly mandrel 16 after 8th , A first round projection 24 follows, the axis 25 of which runs concentrically with the head 20 . The first projection 24 is placed and offset to the axis 25 at a distance X from the second axis 27, followed by a second round projection 26, which has a smaller diameter than the first projection 24. The projections 24 and 26, which are eccentrically offset from one another, enable automatic adjustability for the vertical adjustment of the blind frame member 2 , 2 'on the threshold profile 1, which causes a compression depending on the direction of rotation of the assembly mandrel 16, this 10 with arrow and 11 , or as in 12 shown with an arrow allows loosening with a separation of the two components.

To 10 until 12 are the assembly mandrels 16 in the joined state of the frame member 2 and the connecting elements 10 with the head 20 and the head side 23 rotatable on the back side 18 of the frame member 2, 2 'on. The first projection 24 of the assembly mandrel 16 is the diameter of the bore 17 and the material thickness of the frame member 2, 2 ', as in 5 recognizable, adapted trained. The second projection 26 is also formed in a circular manner in the longitudinal direction of the connecting element 10 arranged transversely to the elongated hole 19 5 recorded as a leader.

The assembly mandrel 16 is after 7 and 8th shaped with its head 20 in the outer contour 28 almost rectangular. Two of the four corners 29 of the original outer contour 28, which are directed diagonally towards one another, have roundings 30 or bevels, which, as in FIG 12 and 14 are designed to move the edge 32 of the web 31 during a turning operation of the assembly mandrel 16 6 , 12 and 14 on the window frame spar 2, 2' for a 90° position and also to overcome a 90° position. As in 6 visible, the web 31 is L-shaped. The edge 32 is perpendicular to the back side 18 of the Window frame spars 2, 2' directed. Another web connects to the free end of the edge 32, spaced parallel to the rear side 18 of the window frame member 2, 2', so that a so-called undercut results. For this purpose, the thickness of the head 20 is adapted in the length of the edge 32 and lies with the lower head side 23 on the back side 18 of the window frame spar 2, 2' in a fully rotatable manner.

For a firm and secure hold of the assembly mandrel 16 seated on the back side 18 of the window frame spar 2, 2 ', the webs 31, which after 5 and 6 preferably form undercuts that are L-shaped in cross section. After turning the assembly mandrel 16 beyond a 90° position, the head 20 is supported with a short side 37 7 its peripheral outer contour 28 at least against the wall of an edge 32 of the web 31 finally reaching under the undercut in a rotationally fixed manner and assumes an end position secured against rotation.

A functionally reliable fastening between the threshold profile 1 with the connecting elements 10 connected thereto in a non-positive manner to form a one-piece component and the frame spar 2, 2' is achieved in that the distance Z according to 9 from the axis of the bore 17 in the window frame spar 2, 2' to the edge 32 of the web 31 arranged on the back side 18 on the window frame spar 2, 2', at a distance Y 7 is adapted from the axis 25 of the first approach 24 to the short side 37 of the head 20 of the mounting mandrel 16. The short sides 37 run to the respective adjoining long sides 38 of the assembly mandrel 16 via the corners 29 forming connection points 39 of the outer contour 28 of the head 20 beyond an obtuse angle of 90° and thus enable the assembly mandrels 16 to be attached in any desired areas of the rear side 18 of the Frame spars 2, 2' can be used with compliance with the dimension Y to the undercut web 30 and, after a rotation beyond a 90° angle, can be supported against further rotation in the undercut area of the web 31.

It can also be advantageous if the mounting mandrel 16 is wedge-shaped in the area of the roundings or bevels 30 on the flat head sides 21, 23, so that they can become wedged in the undercut web 31 in the axial direction when they are rotated. It is particularly advantageous if, according to the innovation, the two roundings or bevels 30 on the assembly mandrel 16 have the same distances from the axis of rotation 25 of the extension 24 .

When the end position of the system is reached with the pressed position of the frame member 2, 2' on the threshold profile 1 and the threshold connector 3 by the assembly mandrel 16, the present position decreases 11 by screwing in fastening screws 33, starting from the rear side 18 through the window frame spar 2, 2' and the connecting elements 10, secure in a non-positive manner. Finally, the assembly mandrels 16 as in 12 identified and removed again.

If the threshold profile 1 or ground threshold used according to the invention is to be used as a post profile for using a system for mounting a window frame spar 2 to be connected to the end of the threshold 1, the window frame spar 2, 2' is preferably cut to length at right angles. Next, a threshold connector 3 can be 2 For the sake of simplicity, connect it to the threshold profile 1 by screwing fastening screws 34 onto a lowered outside step surface 5 of the threshold profile 1, so that a flush plane 9 is formed with a second upper side 7 of the outer contour and of the threshold profile 1, which according to 3 placing a sealing pad 8 on the flush plane 9 of the threshold profile 1 and the threshold connector 3 in a form-fitting and/or non-positively completely covered position of at least one cross-sectional area of the window frame spar 2, 2' is made considerably easier. Furthermore, the placement of connecting elements 10, in this exemplary embodiment with two connecting elements 10, follows on to the threshold profile 1 4 , which by means of screws 11 from the underside 12, the side facing away from the threshold profile 1 to level 9, connecting a non-positive connection with the threshold profile 1 enter. With further placement of the window frame spar 2 on the sealing pad 8 5 by positively fitting onto the connecting elements 10 in complementary arranged hollow chambers 13 of the window frame spar 2, 2', a positive connection is already advantageously obtained, with corresponding support and upright seating of the window frame spar 2, 2' to the threshold profile 1 and the threshold connector 3. For a sealing effect is then after 9 until 12 the window frame spar 2, 2' is pressed against the threshold profile 1 and the threshold connector 3. Essential for this are recesses 14, 15 in the connecting element 10 and in the frame member 2, 2 'and the use of an assembly mandrel 16 provided with lugs 24, 26, which due to its eccentricity between the lugs 24, 26 during rotation in the recesses 14, 15 Tightening causes. This results in a compressing effect on the sealing pad 8. A permanently secure connection for a tensioned final assembly position of the component connection results in a simple manner by means of a non-positive connection further fastening screws 33 after 11 , which are screwed from the rear side 18 of the window frame spar 2, 2' through the spar 2, 2' to the respective connecting element 10, which is fixedly connected to the threshold profile 1, in the assembled end position of the window frame spar 2, 2' to the threshold profile 1.

The assembly mandrels 16 can then be removed by rotating them in the opposite direction to the tightening torque of the system and used again.
