Description

[0001] The present invention relates to a floor bridge for a threshold for a sliding door and / or sliding window system, in particular a lift-and-slide door and / or lift-and-slide window system, which has a wing, in particular a sliding or lift-and-slide wing, and a sliding or lift-and-slide wing that is movable in a sliding direction (V) relative to the wing. Furthermore, the present invention relates to such a threshold for a sliding door and / or sliding window system, in particular a lift-and-slide door and / or lift-and-slide window system, and to a sliding door and / or sliding window system, in particular a lift-and-slide door and / or lift-and-slide window system.

[0002] A sliding window and / or sliding door system usually has at least two window and / or door elements, which are also referred to below as sashes. In such sliding systems, at least one movable sliding sash and at least one further sash, which can for example also be a sliding sash or a fixed or stationary sash, are provided. This means that the sliding sash has a sliding device which enables a translational relative displacement with respect to the further sash and with respect to the stationary frame. In a lift and slide system, a lift and slide unit is provided on at least one of the sashes, which makes it possible to lift this sash and then slide it linearly. Such sashes usually have a sash profile frame which is attached to a base or wall which is adjacent to the floor or ceiling.The underside of the profile frame facing the substructure has a carriage that is mounted on a guide rail to lift the sash and move it translationally. A guide rail is understood to be a threshold-side guide for the sliding sash carriage that extends across the entire threshold width.

[0003] For example, at least one pair of carriages or at least two separate carriages connected by a connecting rod can be used. After the sash has been moved, it can be lowered again, meaning the carriage is retracted and further movement of the sash is prevented. The bottom-side, horizontally extending part of the frame, which encloses the track, is also called the threshold.

[0004] One disadvantage is the high vertical height of existing thresholds. These cannot meet the demand for ever-lower vertical heights, especially for so-called barrier-free sliding door and / or sliding window systems, especially lift-and-slide door and / or lift-and-slide window systems.

[0005] Another challenge in the design and installation of sleepers is that the subfloors or floors on which the sleepers are installed can vary depending on the material surface, the rigidity of the material, and / or the height dimensions, which create different gaps or spaces between the sleeper and the floor. However, the goal is for the sleepers to be usable regardless of whether the floor or subfloor is natural stone, tiled, parquet, or even marble, which, for example, has a high movement tolerance.

[0006] To bridge gaps between the threshold and the floor or substructure, height adjustment profiles are used, for example, in accordance with DE 20 2012 001 082 U1. The height adjustment profile is constructed in several parts and comprises a connecting part for attachment to the threshold, a movable or movable bridging part, and a securing part for securing the sealing part to the connecting part. On the one hand, installation of the height adjustment profile in accordance with DE 20 2012 001 082 U1 has proven to be cumbersome. Furthermore, the height adjustment profiles are limited in their orientation options relative to the threshold. Either a single predefined installation position can be adopted, or the height adjustment profile can be moved freely, which can lead to it moving out of the correct operating position.

[0007] It is an object of the present invention to overcome the disadvantages of the known prior art, in particular to provide a floor bridge for a threshold of a sliding door and / or sliding window system which is easier to install and / or more flexible to use.

[0008] The problem is solved by the subject matter of the independent claims.

[0009] According to this, a floor bridge for a threshold is provided for a sliding door and / or sliding window system, in particular a lift-and-slide door and / or lift-and-slide window system, which has one sash, in particular a sliding or lift-and-slide sash, and one sliding or lift-and-slide sash that is movable in a sliding direction relative to the other sash. The floor bridge can also be used for a front door threshold, a threshold of a revolving door, or other door and / or window thresholds.

[0010] Thresholds can be located at the transition between an interior floor of a building and an exterior floor outside the building and / or generally serve to cover butt joints, form a bottom stop for a door or window in order to protect or seal the interior of a house or apartment against noise, water and / or drafts. Sliding door or sliding window systems can have a sliding sash and another sash, which can also be a sliding sash or a stationary sash with a fixed frame and / or frame, whereby the sliding sash is movable in one direction relative to the other sash. In a sliding system with two sliding sashes, both sliding sashes can be moved relative to the other sliding sash.A lift-and-slide door and / or lift-and-slide window system typically comprises a lift-and-slide sash and another sash, which may be a fixed sash or a lift-and-slide sash. The lift-and-slide sash is designed to be movable relative to the other sash in a sliding direction and is further designed to be lifted vertically so that it can then be displaced in the sliding direction. The sliding direction of the sliding sash or lift-and-slide sash essentially corresponds to the longitudinal direction of the sill. The sill can typically be referred to as the bottom-side, essentially horizontally extending part of a frame of the window or door. The sill can connect two vertical frame parts arranged at a distance from one another and / or be arranged between them.

[0011] The floor bridge according to the invention can fundamentally be designed to seal the sleeper from the floor or subsurface and / or to bridge any intermediate spaces or a gap between the floor and the sleeper, optionally with a height offset. The floor bridge comprises a connecting part with a joint head for attachment, in particular in a form-fitting and / or force-fitting manner, to a lateral end face of the sleeper extending in the direction of displacement. Furthermore, the floor bridge comprises a bridging part with a bridging lip for bridging a gap between the subsurface or floor and the sleeper and a joint socket which, in order to couple the bridging part and the connecting part, engages around the joint head, in particular in a form-fitting manner, and which, when coupled to one another, is rotatable relative to the joint head of the bridging part.A seal, for example in the form of a sealing strip or a synthetic polymer such as a surface-crosslinked plastic, preferably silicone, can be arranged on an underside of the bridging part facing the floor, for example in a concave groove. This enables particularly simple installation of the floor bridge to the threshold. In particular, installation takes place in two stages. This means that first the connecting part is mounted on the threshold, in particular plugged, clipped or locked, and then the bridging part is in turn mounted on the connecting part, in particular plugged, pushed or clipped on. Due to the ability of the joint socket to rotate relative to the joint head, the floor bridge can be used very flexibly and adapted to different conditions, i.e. in particular height differences between the threshold and the subsurface or floor that need to be bridged or compensated for.The advantageous assembly is supported by the joint head being pushed onto and encompassed by the joint socket. For example, when the bridging part and connecting part are coupled together, a rotation angle of up to 150°, in particular up to 125° or 100°, is possible. The bridging lip and the joint socket can be made from a single piece, in particular from metal, such as aluminum. Furthermore, the connecting part can also be made from a single piece. For example, the joint socket and the joint head are constructed like a hinge joint, wherein the joint head in particular can have a cylindrical or fully cylindrical shape, which rests like a pincer-like groove in a joint socket that corresponds to a segment of a hollow cylinder.The joint head, which rests during the relative rotation of the joint socket with respect to the joint head, can provide a bearing surface, in particular a sliding bearing surface, of more than 190°, in particular of more than 235° or more than 270°.

[0012] In an exemplary embodiment of the floor bridge according to the invention, the joint head and the joint socket are coordinated with one another in such a way that the joint socket slides along the joint head during a relative rotational movement. Alternatively or additionally, the joint socket and the joint head can be coordinated with one another in such a way that the joint socket is guided by the joint head in a relative rotational movement. In an exemplary further development, the arrangement, in particular the coordination of the joint socket and the joint head, ensures, on the one hand, the fastening of the bridging part and the connecting part to one another and, on the other hand, the relative movement, in particular relative rotation, of the connecting part and the bridging part. Due to the functional union thus created, the floor bridge is particularly simple in construction and easy to operate.

[0013] According to a further aspect of the present invention, which can be combined with the previous aspects and exemplary embodiments, a floor bridge is provided for a threshold for a sliding door and / or sliding window system, in particular a lift-and-slide door and / or lift-and-slide window system. The floor bridge can also be used for a front door threshold, a threshold of a revolving door, or other door and / or window thresholds.

[0014] According to this, a floor bridge for a threshold for a sliding door and / or sliding window system, in particular a lift-and-slide door and / or lift-and-slide window system, which has a wing, in particular a sliding or lift-and-slide wing, and a sliding or lift-and-slide wing which is movable in a sliding direction relative to the other wing, is provided.

[0015] Thresholds can be located at the transition between an interior floor of a building and an exterior floor outside the building and / or generally serve to cover butt joints, form a bottom stop for a door or window in order to protect or seal the interior of a house or apartment against noise, water and / or drafts. Sliding door or sliding window systems can have a sliding sash and another sash, which can also be a sliding sash or a stationary sash with a fixed frame and / or frame, whereby the sliding sash is movable in one direction relative to the other sash. In a sliding system with two sliding sashes, both sliding sashes can be moved relative to the other sliding sash.A lift-and-slide door and / or lift-and-slide window system typically comprises a lift-and-slide sash and another sash, which may be a fixed sash or a lift-and-slide sash. The lift-and-slide sash is designed to be movable relative to the other sash in a sliding direction and is further designed to be lifted vertically so that it can then be displaced in the sliding direction. The sliding direction of the sliding sash or lift-and-slide sash essentially corresponds to the longitudinal direction of the sill. The sill can typically be referred to as the bottom-side, essentially horizontally extending part of a frame of the window or door. The sill can connect two vertical frame parts arranged at a distance from one another and / or be arranged between them.

[0016] The floor bridge according to the invention comprises a connecting part with a joint head for attachment, in particular in a form-fitting and / or force-fitting manner, to a lateral end face of the sleeper extending in the direction of displacement. Furthermore, the floor bridge comprises a bridging part with a bridging lip for bridging a gap between the subsurface or floor and the sleeper, and a joint socket that can be brought into engagement with the joint head to couple the bridging part and the connecting part together.

[0017] According to a further aspect of the present invention, the joint socket can be brought into engagement with the joint head for coupling the bridging part and the connecting part. Furthermore, when the bridging part and the connecting part are coupled together, the joint socket can be rotated relative to the joint head between two end rotation stops.

[0018] This makes it particularly easy to install the floor bridge on the threshold. In particular, assembly takes place in two stages. This means that first the connecting part is mounted on the threshold, in particular by plugging, clipping or locking, and then the bridging part is mounted on the connecting part, in particular by plugging, sliding or clipping on. Due to the ability of the joint socket to rotate relative to the joint head, the floor bridge can be used very flexibly and adapted to different conditions, in particular to height differences that need to be bridged or compensated for between the threshold and the subsurface or floor. For example, when the bridging part and connecting part are coupled together, a rotation angle of up to 150°, in particular up to 125° or 100° is possible.The bridging lip and the joint socket can be made from a single piece, in particular from metal, such as aluminum. Furthermore, the connecting part can also be made from a single piece. For example, the joint socket and the joint head are constructed in the manner of a hinge joint, wherein the joint head, in particular, can have a cylindrical or fully cylindrical shape, resting in a pincer-like groove-like joint socket that corresponds to a segment of a hollow cylinder. The joint head, which rests with respect to the joint head during relative rotation of the joint socket, can provide a bearing surface, in particular a sliding bearing surface, of more than 190°, in particular more than 235° or more than 270°.

[0019] The provision of two end-of-rotation stops, with one end-of-rotation stop being responsible for one direction of rotation and the other for the opposite direction, fulfills several functions. Firstly, they define the final assembly positions, thus preventing incorrect operation or assembly positions, for example, which would result in unwanted disassembly of the connecting part and the bridging part. Furthermore, the end-of-rotation stops help ensure that the bridging part remains in the respective position relative to the connecting part when assuming the final rotation positions.

[0020] According to an exemplary embodiment of the floor bridge according to the invention, a rotation angle defined by the two end rotation stops is at least 60°, in particular at least 70°, 80°, or at least 90°, preferably up to 100°. The angle defines the range of motion of the bridging part relative to the connecting part.

[0021] In a further exemplary embodiment of the floor bridge according to the invention, the two end-of-rotation stops are formed by two pairs of mutually associated stop surfaces of the connecting part and the bridging part. In other words, the connecting part and the bridging part each have two stop surfaces, with one stop surface of the connecting part and the bridging part coming into contact with the other when the respective end-of-rotation stop is assumed.

[0022] In a further exemplary development of the floor bridge according to the invention, the joint head is C-shaped in cross-section and has a projection on both C-legs. The projections are designed to abut against a bearing web that partially forms the joint socket. Because the components or structures forming the end rotation stops are each formed from a single piece with a bridging part or bearing part, a floor bridge with a particularly simple structure is provided. The projections on the C-legs extend from the C-legs in such a way that they extend counter to the circumferential direction or main extension direction of the C-legs. For example, the bearing webs have a concave receiving surface facing the joint head and / or a substantially thin-walled web against which the projections of the C-legs can abut.

[0023] In a further exemplary embodiment of the present invention, the joint head is substantially cylindrical, in particular substantially fully cylindrical, or cylindrical in shape. For example, the connecting part further comprises a web that can be placed flush with an upper side of the sleeper and that opens into the joint head. The web can form a substantially flat surface.

[0024] In particular, the joint head is formed as a single piece with the base piece. For example, the web forms one of the two end rotation stops on the connecting part side. In a further exemplary embodiment of the present invention, the joint socket has a concave receptacle for the joint head. For example, the receptacle is designed in the shape of a circular arc. Alternatively or additionally, a central angle is more than 180°. Due to the resulting engagement of the joint head by more than 180°, the bridging part does not require a separate fastening device in order to remain arranged or fixed to the connecting part. The angle, in combination with the precise coordination of the joint head and joint socket, enables relative rotation on the one hand and the mutual fastening of the bridging part and the connecting part.

[0025] According to an exemplary development of the floor bridge according to the invention, the joint socket-side stop surfaces are formed by the opposite ends of the concave receptacle, in particular the circular arc. The joint socket can, for example, have a C-shaped form. The front end surfaces of the C-structure can each form the stop surfaces, which can come into contact with the respective stop surfaces on the connecting part to form the final rotation stops.

[0026] According to a further exemplary embodiment of the present invention, the connecting part has two locking elements, such as two locking projections, which are each designed to engage with a sleeper-side locking element, such as a locking recess, in order to attach the connecting part to the sleeper. A locking element can be formed on the web, in particular made in one piece with it. In this way, a particularly simple assembly of the connecting part to the sleeper can be achieved. For example, one of the locking elements serves to positionally attach the connecting part to the sleeper. The other connecting part locking element can serve for the final fastening of the connecting part to the sleeper, in which the connecting part attached to the sleeper by means of the first locking element is finally brought into further engagement with the sleeper via the further locking element.

[0027] In an exemplary development of the floor bridge according to the invention, a locking element on the connecting part side, in particular an upper locking element, is designed as a particularly cylindrical joint head and / or can be or is gripped around in a pincer-like manner by the associated sleeper-side locking element, in particular an inner-shaped locking element designed as a joint socket, in particular a locking element arranged on an upper side of the sleeper. For example, the locking element pairs form a hinge joint. In this case, the locking element on the connecting part side can be attached to the sleeper in an assembly orientation and brought into the assembly position by means of interaction with the sleeper-side locking element. For example, the engagement of the further locking element pair then takes place in the assembly position in order to fasten the connecting part in place.

[0028] According to a further exemplary embodiment of the floor bridge according to the invention, a locking element on the connecting part side, in particular a lower locking element, is designed to engage behind a profile web on the sleeper side in a transverse direction oriented transversely to the direction of displacement, in particular to prevent the connecting part and sleeper from moving apart in the transverse direction. For example, the pair of locking elements interacts with each other in the manner of a locking or clip mechanism.

[0029] According to a further aspect of the present invention, which can be combined with the preceding aspects and exemplary embodiments, a threshold is provided in particular for a sliding door and / or sliding window system, in particular a lift-and-slide door and / or lift-and-slide window system, which has a wing, in particular a sliding or lift-and-slide wing, and a sliding or lift-and-slide wing which is movable in a sliding direction relative to the other wing.

[0030] The sleeper according to the invention comprises a lateral end face extending in the direction of displacement. The lateral end face can be substantially planar, at least in sections, and / or oriented transversely, in particular perpendicularly, to a sleeper base surface defining the upper side.

[0031] The threshold according to the invention further comprises a floor bridge according to the invention, which can be designed according to one of the aspects described above or one of the exemplary embodiments described above and whose connecting part is attached in particular in a form-fitting and / or force-fitting manner to the end face and whose bridging part is in engagement with the connecting part.

[0032] According to a further aspect of the present invention, which can be combined with the preceding aspects and exemplary embodiments, a sliding door and / or sliding window system, in particular a lift-and-slide door and / or lift-and-slide window system, is provided. The sliding system or the lift-and-slide system can comprise a sliding sash or a lift-and-slide sash, which is made, for example, of plastic, as well as a further sash, which is preferably made of plastic and can be a fixed sash, a sliding sash, or a lift-and-slide sash.

[0033] The sliding door and / or sliding window system according to the invention comprises a sliding or lifting-sliding sash, preferably made of plastic, which is preferably manufactured using a plastic extrusion process, and another sash, preferably made of plastic, which can also be manufactured using an extrusion process, in particular a sliding or lifting-sliding sash. The sliding or lifting-sliding sash is movable in a sliding direction relative to the other sash. If both sashes are movable or displaceable, they can each be displaced relative to the other in the sliding direction.

[0034] The sliding door and / or sliding window system according to the invention also comprises a threshold, particularly designed according to the invention, with a guide rail groove and a guide device completely accommodated in the guide rail groove, such as a guide rail that is designed to engage with a carriage of the sliding or lift-and-slide sash. Because the guide device is completely accommodated in the guide rail groove, or in other words, does not protrude vertically beyond or out of the guide rail groove, the sliding door and sliding window system according to the invention is particularly advantageously suited to today's requirements and efforts to create barrier-free transitions between building spaces or between a building space and the surrounding area.In addition, it is possible to seal the interface between the sliding or lift-sliding sash and the threshold more effectively or in a simpler way, since the interface is smaller compared to state-of-the-art designs.

[0035] According to a further aspect of the present invention, which can be combined with the previous aspects and exemplary embodiments, a sliding door or sliding window system, in particular a lift-and-slide door and / or lift-and-slide window system, is provided, which can be designed according to one of the previously described aspects, for example exemplary embodiments.

[0036] The sliding door and / or sliding window system according to the invention comprises a sliding or lifting-sliding sash, preferably made of plastic, which is preferably manufactured using a plastic extrusion process, and another sash, preferably made of plastic, which can also be manufactured using an extrusion process, in particular a sliding or lifting-sliding sash. The sliding or lifting-sliding sash is movable in a sliding direction relative to the other sash. If both sashes are movable or displaceable, they are each movable in the sliding direction relative to the other.

[0037] The sliding door and / or sliding window system according to the invention also comprises a threshold, in particular designed according to the invention, with a guide rail groove and a guide device arranged therein, in particular completely accommodated therein, such as a guide rail, which is designed to come into guide engagement with a carriage of the sliding or lift-sliding sash.

[0038] According to a further aspect of the invention, the guide device comprises a locking part for positive and / or non-positive connection to a locking element of the threshold, in particular one with a corresponding shape. This enables the installation of the sliding door and / or sliding window system in a particularly simple manner. The locking mechanism offers the advantage that defined installation is possible even for inexperienced installation personnel. Furthermore, the locking mechanism ensures that the guide device assumes the correct position or orientation in the track groove, in particular to ensure reliable movement of the sliding or lift-and-slide sash.

[0039] In an exemplary development of the sliding door and / or sliding window system according to the invention, the sill-side locking element is designed as a groove with a T-shaped cross-section, and the guide-device-side locking part has at least one locking projection, in particular two locking projections, which engage behind a T-leg of the groove, in particular locking or clipping thereto. Due to the mutual rear engagement of the locking parts, the guide device is securely positioned in the guide rail groove.

[0040] In an exemplary embodiment of the present invention, the guide device-side locking part is dimensioned, in particular oversized, relative to the sleeper-side locking element in such a way that the guide device-side locking part is elastically deformed when assuming the final assembly position. For example, the elastic deformation can be eliminated again in the final assembly position. Alternatively, it is possible for a certain elastic deformation to still be present in the final assembly position, so that an elastic deformation restoring force is built up that reinforces the mutual attachment of the guide device and the sleeper.

[0041] According to a further aspect of the present invention, which can be combined with the previous aspects and exemplary embodiments, a sliding door or sliding window system, in particular a lift-and-slide door and / or lift-and-slide window system, is provided, which can be designed according to one of the previously described aspects, for example exemplary embodiments.

[0042] The sliding door and / or sliding window system according to the invention comprises a sliding or lifting-sliding sash, preferably made of plastic, which is preferably manufactured using a plastic extrusion process, and another sash, preferably made of plastic, which can also be manufactured using an extrusion process, in particular a sliding or lifting-sliding sash. The sliding or lifting-sliding sash is movable in a sliding direction relative to the other sash. If both sashes are movable or displaceable, they are each movable in the sliding direction relative to the other.

[0043] The sliding door and / or sliding window system according to the invention also comprises a threshold, in particular designed according to the invention, with a guide rail groove and a guide device arranged therein, in particular completely accommodated therein, such as a guide rail, which is designed to come into guide engagement with a carriage of the sliding or lift-sliding sash.

[0044] According to a further aspect of the invention, the guide device comprises a base resting on a groove base and at least one support arm protruding from the base, in particular two lateral, in particular identical and / or mirror-inverted support arms, which are dimensioned for flush connection to the top of a sleeper. This allows the formation of a smooth, in particular step-free and / or moisture-sealed transition between the guide device and the sleeper. Furthermore, a groove in the sleeper can be avoided, which poses the risk of dirt or moisture entering or causing injury or tripping.

[0045] According to one exemplary embodiment, the support arm is tightly pressed against a side wall of the guide rail groove. This provides particularly good protection against the ingress of dirt or moisture.

[0046] According to a further aspect of the present invention, which can be combined with the preceding aspects and exemplary embodiments, a method is provided for mounting a floor bridge, in particular designed according to one of the preceding aspects and exemplary embodiments, on a threshold, in particular designed according to the invention, for a sliding door and / or sliding window system, in particular a lift-and-slide door and / or lift-and-slide window system, with a sliding or lift-and-slide sash and a further sash, in particular a sliding or lift-and-slide sash, wherein the sliding or lift-and-slide sash is movable in a sliding direction relative to the further sash. The features and embodiments previously disclosed with regard to the aspects of the invention relating to the floor bridge, the threshold and the sliding door and / or sliding window system apply analogously to the mounting method according to the invention.

[0047] According to the method, a connecting part of the floor bridge is plugged in a plug-on direction onto a lateral end face of the sleeper extending in the direction of displacement. The plug-on direction can be oriented in the range of 15° to 45°, in particular by approximately 30°, relative to the planar extension of the sleeper, in particular relative to the horizontal. Furthermore, a bridging part of the floor bridge is brought into coupling engagement with the connecting part in a coupling orientation along a coupling direction. The connecting part thus assumes a pre-assembled state with the bridging part. Furthermore, the bridging part is rotated about a rotation axis determined by the coupling engagement into a bridging orientation for bridging a gap between the subsurface or floor and the sleeper. In the bridging orientation, the bridging part is firmly mounted to the connecting part.A rotation angle of just a few degrees is sufficient for the parts to self-lock, preventing the bridging part and connecting part from moving apart. A key advantage is the simple, tool-free assembly and disassembly of the floor bridge. Disassembly can be performed in reverse order.

[0048] According to an exemplary development of the assembly method according to the invention, the connecting part is locked into place when it is placed on the threshold. This ensures that the connecting part is securely positioned and held on the threshold.

[0049] According to a further aspect of the present invention, which can be combined with the preceding aspects and exemplary embodiments, a floor bridge for a threshold for a sliding door and / or sliding window system, in particular a lift-and-slide door and / or lift-and-slide window system, which has a wing, in particular a sliding or lift-and-slide wing, and a sliding or lift-and-slide wing which is movable in a sliding direction (V) relative to the wing, is provided.

[0050] The floor bridge comprises a connecting part with a joint head for attachment, in particular in a form-fitting and / or force-fitting manner, to a lateral end face of the sleeper extending in the direction of displacement, and a bridging part with a bridging lip for bridging a gap between the subsurface or floor and the sleeper, and a joint socket which can be brought into engagement with the joint head for coupling the bridging part and the connecting part together.

[0051] According to this aspect of the invention, the floor bridge comprises exclusively the connecting part and the bridging part. In other words, the floor bridge is formed in two parts.

[0052] Furthermore, the floor bridge can be designed such that it can be connected to the threshold without additional fastening devices, such as screws or the like. The floor bridge can be plugged, snapped, and / or clipped on. For example, the installation and / or removal of the floor bridge, in particular the connecting part and / or the bridging part, can be carried out without tools.

[0053] According to a further aspect of the present invention, which can be combined with the preceding aspects and exemplary embodiments, the floor bridge is designed to form a barrier-free transition between the subsurface or floor and the threshold. The connecting part and / or the bridging part can be designed to form a flush, in particular step-free, transition to the subsurface or floor or threshold.

[0054] Preferred embodiments are specified in the subclaims.

[0055] In the following, further properties, features and advantages of the invention will become clear by describing preferred embodiments of the invention with reference to the accompanying exemplary drawings, in which: Figure 1 a perspective view of an exemplary embodiment of a threshold according to the invention; Figure 2 a perspective sectional view of an exemplary embodiment of a sliding door and / or sliding window system according to the invention; Figures 3 to 7 an assembly process of an exemplary embodiment of a floor bridge according to the invention on a sleeper; Figure 8 a further exemplary embodiment of a floor bridge according to the invention; Figure 9 an exemplary embodiment of a sliding door and / or sliding window system according to the invention Figure 10 a further exemplary embodiment of a threshold according to the invention; Figure 11 a perspective view of the guide device Figure 10 ; Figure 12 a further exemplary embodiment of a threshold according to the invention; and Figure 13 a perspective view of the guide device Figure 12 .

[0056] In the following description of exemplary embodiments of the present invention, a floor bridge according to the invention, which is intended for use on a threshold for a sliding door and / or sliding window system, is generally provided with the reference numeral 1. A threshold according to the invention is generally provided with the reference numeral 10 and a sliding door and / or sliding window system according to the invention with the reference numeral 100. The threshold 10 can have any desired installation height and be made of any desired material, such as wood, plastic or aluminum. If door and / or window profiles are mentioned in the following description, it can be assumed that these are plastic profiles produced by an extrusion process, in particular made of PVC, which have an extrusion direction in which they have a constant cross-section.

[0057] In Figure 1A perspective sectional view of a sleeper 10 according to the invention is shown, to which a floor bridge 1 according to the invention is attached. The sleeper 10 comprises two guide rail grooves 13, 15 extending in a displacement direction V, each of which is intended to receive a guide device, such as a guide rail, with which a carriage 103 of a sliding and / or lift-and-slide sash 105 can be engaged and cooperates therewith to displace the sliding or lift-and-slide sash 105 in the displacement direction V. The sleeper 10 has a cross-section that is essentially constant along its longitudinal extent in the displacement direction V. In a central region, the sleeper 10 comprises a flat sleeper surface 19 and two lateral surfaces 21, 23, each adjoining one of the guide rail grooves 13, 15.

[0058] For example, in Figure 1As can be seen, the floor bridge 1 is mounted on a lateral end face 25 of the sleeper 10. The attachment or arrangement of the floor bridge 1 on the sleeper 10 is such that the lateral sleeper surface 23 is flush with the floor bridge 21, or the latter adjoins it flush, so that a web 27 forming the upper side of the floor bridge 1 essentially forms a direct extension of the sleeper surface 23. As further shown in the Figures 2 and 3 As can be seen, the sleeper 10 comprises several hollow chambers 29 extending in the direction of displacement V, which can be used either unoccupied or to accommodate stiffening parts.

[0059] Referring to Figure 2, in which an exemplary embodiment of a sliding door and / or sliding window system 100 according to the invention is depicted, the threshold 10 rests on a substrate 108 by means of a substructure profile 107, which is constructed in two parts, for example, and the floor bridge 1 bridges a gap 109 resulting between the threshold 10 and a floor covering 108 installed on a screed 110, in order to bridge this gap in a particularly sealing manner. Figure 2The guide rail groove 13 facing away from the floor bridge is covered with a cover profile 19, which is arranged in a locking manner in the guide rail groove 13 and creates a flat and flush transition with adjacent surfaces 19, 21 of the threshold, so that a continuous upper side or surface is formed. In the area of the further groove 15 near the floor bridge, a guide device designed as a guide rail 17 is arranged for the thus displaceable sliding and / or lift-sliding sash 105. For this purpose, the sliding and / or lift-sliding sash 105 has a carriage 103 arranged in a guide groove 112 provided on an underside of the sliding and / or lift-sliding sash 105. The sliding and / or lift-sliding sash 105 further has a sash rebate 111 arranged on an upper side for receiving glazing.

[0060] Based on the Figures 3 to 8exemplary embodiments of floor bridges 1 according to the invention as well as their advantageous assembly process with respect to the sleeper 10 are explained in more detail. Firstly, referring to Figure 6 7, respectively, the assembled state of the floor bridge 1 on the sleeper 10 is shown in two different operating positions. The floor bridge 1 comprises a connecting part 3 with a joint head 5 for attachment to the end face 25 of the sleeper 10 and a bridging part 7 that can be coupled to the connecting part 3 and has a bridging lip 9 and a joint socket 31 for coupling the bridging part 7 and the connecting part 3. The bridging lip 9, which extends schematically over the gap 109 ( Figure 2 ), may have a structuring 15 on its upper side 13 facing the environment, which may, for example, extend parallel to the displacement direction V.

[0061] In Figure 3a pre-assembly state is shown in which the connecting part 3 is first plugged onto the lateral end face 25 of the sleeper 10 in a plug-on direction A ( Figure 3 ). The insertion direction A is inclined relative to a transverse direction Q extending transversely, in particular perpendicularly, to the displacement direction V. In other words, the connecting part 3 is placed obliquely against the lateral end face 25. A locking and joint mechanism 37 is used, which has a sleeper-side locking part in the form of a concave groove 39 and a connecting part-side locking element in the form of a convex projection 41. When placing the connecting part 3 onto the sleeper 10, the locking and joint projection 41 is therefore first positioned in the locking and joint recess 39 ( Figure 4 ) and, using the locking and joint mechanism 37, rotated about the displacement direction V and brought into a locking engagement with the sleeper 10 ( Figure 5). The locking and joint element 41 on the connecting part side is designed as a cylindrical joint head and, together with the groove-shaped locking element on the sleeper side, designed as a joint socket, forms a hinge joint. For locking and securely holding the connecting part 3 on the sleeper 10, the connecting part 3 has a further locking element, which is arranged on an underside 43 of the connecting part and is designed to engage behind a sleeper-side profile web 45 of the sleeper 10. In the assembled state according to Figure 5 The connecting part 47 engages behind the profile web 45 of the sleeper 10 in the transverse direction Q, so that a separation of the sleeper 10 and the connecting part 3 in the transverse direction Q is prevented. The connecting part 3 rests in a defined and flat manner on the end face 25 of the sleeper 10 by means of a contact projection 49. When the connecting part 3 is locked onto the sleeper 10, i.e. at the transition from Figure 4 on Figure 5 , the joint and locking part 41 slides or locks completely into the corresponding locking element 39 on the threshold side.

[0062] Finally, the bridging part 7 is pushed onto the connecting part in a coupling orientation along a coupling direction K which is inclined with respect to the transverse direction Q and brought into coupling engagement therewith ( Figure 5 ). To assume an operating position of the ground bridge, the bridging part 7 is rotated about a rotation axis determined by the coupling engagement into a bridging orientation for bringing it into contact with the ground or the ground 107 (cf. Figures 6 and 7 ).

[0063] The cylindrical or roller-shaped joint head 5 and the sickle- or groove-like joint socket 31 cooperate in the manner of a hinge joint, in that the joint head 5 is accommodated in a receptacle 51 formed by the joint socket 31 and is rotatable relative to one another in the coupling engagement in order to rotate the bridging part 7 relative to the connecting part 5. The connecting part 3 and the bridging part 7 are coordinated to form two end rotation stops, between which the bridging part 7 is rotatable relative to the connecting part 3. The end rotation stops are formed by two pairs of mutually associated stop surfaces 53, 53' and 55, 55'. A final rotation position is in Figure 7, in which the stop surfaces 55, 55' are in contact with each other and further rotation of the bridging part 7 in the clockwise direction relative to the connecting part 3 is prevented. The other rotation stop is formed by the impact of the bridging part-side stop surface 53 on the connecting part-side stop surface 53' formed by the web 27 when the bridging part 7 is rotated counterclockwise relative to the connecting part 3.

[0064] In Figure 8 Another exemplary embodiment of a floor bridge 1 according to the invention and an associated sleeper 10 is shown. The design of the floor bridge 7 from Figure 8differs from the previous embodiment of the floor bridge 1 in that the separate connecting part 3 of the floor bridge is omitted or is formed by the sleeper 10, which comprises a pivot bearing receptacle 57 for receiving the bridging part 7 with the bridging lip 9, which is formed by two profile webs 63 of the sleeper 10 forming a concave receiving and bearing surface 61.

[0065] The bridging part 7 has a matching C-shaped bearing ring 65, which rests on the bearing webs 63 and is rotatable relative to them in order to be able to assume different positions for the bridging lip 9. The two end rotation stops are formed by the bearing webs 63, which have the respective inwardly facing stop surfaces 53' and 55', as well as by a projection 67 projecting on each of the C-legs, which have the stop surfaces 53, 55. The sleeper 10 or the bridging part 7 according to Figure 8further comprises a securing part 69, which is hammer-shaped, for example, and has a securing projection 71 with a bearing surface 73 adapted to the convex shape of the ring 65 to ensure relative rotation. The securing part 69 is inserted into a receiving groove 75 formed between the lateral end face 25 and the bearing web 63 facing it and is clamped or locked therein to hold the bridging part 7 in position or to prevent accidental disassembly of the bridging part 7.

[0066] Taking into account the Figures 3 and 9 A further aspect of the present invention emerges. Figure 9 shows an embodiment of a sliding door and / or sliding window system 100 according to the invention, by way of example, with the floor bridge 1 according to Figure 8. In addition to the sliding and / or lift-and-slide leaf 105, the system 100 comprises a further leaf 113, which can be, for example, inactive leaves, each sealed against the surface 19 of the threshold 10 by means of seals 115. The guide rail 17 comprises two locking arms or locking feet 117 extending downwards opposite to the vertical direction H, which are designed to lock and engage behind corresponding locking projections 119 on the threshold side in order to securely fix the guide rail 17 in the guide rail groove 15.

[0067] For easy installation, the locking projections 119 are slightly bevelled. As shown in Figure 9As can be seen, the guide device 17 does not extend beyond the extent of the guide rail groove in the vertical direction H, but rather is as flush with it as possible, so that there is no barrier in the area of the guide rail, for example, for wheelchair users. This is also achieved, for example, by a guide lug 121 being countersunk into the guide rail 17 and not protruding beyond adjacent legs of the guide rail 17 in the vertical direction H.

[0068] In the Figures 10 and 12 exemplary embodiments of sleepers 10 according to the invention are shown with exemplary embodiments of floor bridges 1 according to the invention and in the Figures 11 and 13 the respective guide devices 17 in perspective view.

[0069] According to the execution according to the Figures 10 and 11The guide device 17 comprises a base 123 resting on a groove bottom, from which the locking parts 117 extend downwards for positive engagement with locking projections 119 on the sleeper side, and two lateral support arms 125 extending upwards from the base 123, which are dimensioned such that they do not protrude above a sleeper upper side 127 in the vertical direction H and are flush with it. This provides particularly good sealing in the area of the transition between the guide device 17 and the sleeper 10, as well as protection against injury to people. During assembly, the support arms 125 can be pressed into the guide rail groove 13, 15 with a side wall 129 of the guide rail groove 13, 15. This can be accompanied by a particularly elastic deformation of the support arms 125, which results in a particularly elastic deformation restoring force, which improves the sealing effect in the area of the transition.

[0070] According to the design of threshold 10 in the Figures 12 and 13 a cost-effective variant of the guide device 17 is shown, which does not require the protruding locking arms 125, but is otherwise essentially identical.

[0071] The features disclosed in the above description, the figures and the claims may be important both individually and in any combination for the realization of the invention in the various embodiments. List of reference symbols
