Description

[0001] Threshold for supporting a horizontal frame profile leg of a fixed-field wing

[0002] The present invention relates to a threshold for supporting a horizontal frame profile leg of a fixed panel sash, in particular a lift-and-slide door or a lift-and-slide window, on a building structure.

[0003] Lift-sliding doors usually have a fixed panel leaf, in front of which the movable leaf of the sliding door can be pushed to open the sliding door. The glazing of the fixed panel leaf is located in a surrounding frame, the horizontal and vertical legs of which are formed by a hollow chamber profile. The lower horizontal frame profile leg rests on a threshold that is embedded in the floor slab of a building so that the surface of the threshold is as flush as possible with the surface of the floor slab. In order to secure the lower horizontal frame profile leg of the fixed panel leaf to the threshold perpendicular to its plane, a pin formed integrally with the floor surface usually protrudes from the floor surface. This pin is received by a fitting groove formed on the outside in the hollow chamber profile of the lower horizontal frame profile leg.

[0004] The tenon(s) formed integrally with the threshold should have a height dimension that is a few millimeters greater than the depth of the fitting groove, so that the lower horizontal frame profile leg rests on the tenon(s) above or with the groove base of the fitting groove. However, since the hollow chamber profiles from different manufacturers have fitting grooves of different depths, it is necessary to have different thresholds with tenons available, each of which has a height dimension that is individually matched to the fitting groove of the respective hollow chamber profile.

[0005] It would therefore be desirable to be able to use one and the same threshold for different hollow chamber profiles.

[0006] The invention is therefore based on the object of fulfilling this wish.

[0007] To solve this problem, a speed bump is presented for the first time which is characterized by the features of claim 1.

[0008] The threshold according to the invention has a threshold profile that can be attached directly or indirectly to a building structure, such as a floor slab, via a threshold base body that accommodates the threshold profile. If the threshold or its threshold profile is attached indirectly to the building structure via a threshold base body, the threshold acts as a kind of intermediate profile, as the fixed field wing transfers its weight to the threshold base body via this.

[0009] The threshold profile has a surface from which an adapter part extends, which is to be received by a fitting groove formed along a horizontal frame profile leg of a fixed-panel sash. The adapter part, in turn, has a mounting surface spaced from the surface of the threshold profile, on which at least one compensating plate is provided, by means of which the distance between the mounting surface of the adapter part and the groove base of the fitting groove of a horizontal frame profile leg can be bridged.

[0010] According to the invention, it is thus provided, in a sense, to double the adapter part by means of one or more compensating plates in order to be able to adapt the combined height dimension of the adapter assembly comprising the adapter part and the at least one compensating plate to the groove depth of the fitting groove of the respective hollow chamber profile. For hollow chamber profiles with different depths of fitting grooves, therefore, different thresholds with different heights of pins are not required; rather, one and the same threshold can be used for hollow chamber profiles with different depths of fitting grooves, whereby only different thicknesses of compensating plates need to be provided to adapt to different depths of fitting grooves.

[0011] Similar considerations apply if the adapter part is a separate part from the threshold profile and is detachably connected to the threshold profile, for example, by means of a locking mechanism, since in this case, adapter parts with different height dimensions do not need to be kept in stock. Rather, a standard adapter part can be doubled up with one or more compensation plates in the manner according to the invention, so that different adapter parts do not need to be kept in stock for hollow chamber profiles from different manufacturers, possibly with different depths of fitting grooves.

[0012] The adapter plate can advantageously be a standard component that can also be used elsewhere in a fitting groove of a hollow chamber profile. For example, the movable leaf of a lift-and-slide door can have a frame made from the same hollow chamber profile as the fixed leaf. In this case, the drive rod assembly, and in particular its faceplate profile, located in the fitting groove of the hollow chamber profile of the movable leaf, can be supported by an adapter plate of the same type at the base of the fitting groove. This also eliminates the need for a separate component, thus reducing the maintenance effort and associated costs.

[0013] Preferred embodiments of the invention will now be discussed below. Further embodiments may also emerge from the dependent claims, the description of the figures, and the drawings themselves.

[0014] While it's not absolutely necessary to connect the leveling plate to the adapter part using any type of fastener, since the leveling plate is held perpendicular to the plane of the fixed-panel sash by the side walls of the hardware groove, it can be advantageous to detachably connect the leveling plate to the adapter part, for example, by means of a conventional locking mechanism and / or frictional engagement, to prevent the leveling plate from slipping off the adapter part during installation of the fixed-panel sash.

[0015] According to one embodiment, the locking mechanism can, for example, comprise at least one tab extending from an underside of the compensating plate facing the mounting surface to a free end formed as a barb that, when locked to the adapter part, engages behind an undercut section formed by the adapter part. The adapter plate thus does not have to be laboriously attached to the adapter part using any type of fastening means; rather, the locking mechanism allows the compensating plate to be clipped onto the adapter part while the compensating plate is being placed onto the adapter part.

[0016] According to a further embodiment, it can be provided that the undercut section is formed by an edge section of an opening formed in the mounting surface of the adapter part, into which opening the tab of the compensating plate extends. If the adapter part is, for example, a hollow chamber profile produced by an extrusion process, the opening in question can be a groove extending over the entire length of the mounting surface, which is formed in the mounting surface, wherein a recess forming the undercut section is formed along a side wall of the groove.

[0017] However, if the adapter part is an injection-molded part, it is not absolutely necessary for the opening for accommodating the tab of the compensating plate to extend the entire length of the adapter part's mounting surface. Rather, it may be sufficient to form the opening in the mounting surface only at the exact location where the tab of the compensating plate will be located.

[0018] In order to be able to remove the compensating plate from the adapter part without causing damage, a further embodiment can provide an inspection opening in a side surface of the adapter part, through which an undercut area formed by the undercut section is accessible, for example, with a screwdriver. A barb engaging behind the undercut section can thus be released or disengaged from the undercut section through the inspection opening using a screwdriver, so that the compensating plate can then be removed from the adapter part again.According to a further embodiment, it can be provided that the locking mechanism comprises at least a first and at least a second pair of tabs, wherein the first pair of tabs has a first distance from a first end of the compensating plate and the second pair of tabs has a second distance from a second end of the compensating plate opposite the first end, which deviates from the first distance, and wherein four pairs of openings are formed in the mounting plate for receiving the pairs of tabs, wherein a first pair of openings has the first distance from the first end of the mounting plate, a second pair of openings has the second distance from the first end of the mounting surface, a third pair of openings has the first distance from the second end of the mounting surface and a fourth pair of openings has the second distance from the second end of the mounting surface.Although the two pairs of tabs are spaced at different distances from the two ends of the compensating plate, it is thus possible to attach the compensating plate to the adapter part in two positions offset by 180° from each other. This can prove particularly advantageous if the length of the compensating plate between its first and second ends is equal to the length of the adapter part between the first and second ends of the mounting surface, since in this case the compensating plate can be attached to the adapter part essentially congruent with the mounting surface, regardless of its orientation.

[0019] According to a further embodiment, the compensating plate can be designed as a ribbed plate or as a type of support grid, the ribs of which define several through-openings in the compensating plate. Designing the compensating plate as a ribbed plate proves to be advantageous, on the one hand, in that it saves material, and on the other hand, in that fastening means such as screws for attaching the compensating plate to the adapter part can be passed through the through-openings formed by the ribs. As already mentioned, the adapter part can be a profile part produced using an extrusion process. In this case, the adapter part can be an elongated component that extends over the entire length of the sleeper profile.Alternatively, several sections can be cut from such an extruded profile, which can then be provided as spaced-apart adapter parts along the threshold profile, as is also the case when the adapter parts are manufactured by injection molding.

[0020] In the following, the invention will now be described purely by way of example with reference to the figures in which:

[0021] Fig. 1 shows a sliding door system in view;

[0022] Fig. 2 shows a vertical section through a threshold according to the invention according to the section line AA of Fig. 1;

[0023] Fig. 3A and 3B are perspective views in the area of ​​a fixed panel of a sliding door system; and

[0024] Fig. 4 shows a perspective view of an adapter part arrangement consisting of adapter part and compensation plate.

[0025] Fig. 1 shows a sliding door system 10 with a movable leaf 12 and a fixed leaf 14, wherein the movable leaf 12 can be pushed in a conventional manner from the illustrated closed position in front of the fixed leaf 14 in order to open the sliding door system 10. The glazing 16 of the fixed leaf 14 is located in a surrounding frame 18, which is formed from a hollow chamber profile; see also Fig. 3a.

[0026] Fig. 2 shows, according to section AA of Fig. 1, the lower horizontal frame profile leg 20 of the frame 18 in vertical section, from which it can be seen that the frame profile leg 20 is a hollow chamber profile with a steel core 22. Instead of a hollow chamber profile, the frame profile leg 20 can also be formed, for example, by a solid wooden profile in which a fitting groove is formed, which is explained in more detail below. As can also be seen from Fig. 2, the hollow chamber profile which forms the lower horizontal frame profile leg 20 has a fitting groove 26 on the outside with a groove base 28, wherein a seal 24 is provided on the outside of the frame profile leg 20 on both sides of the fitting groove 26, by means of which seal the lower horizontal frame profile leg 20 is sealed against a sill profile 30 and in particular its surface 32.In the embodiment shown here, the threshold profile 30 is an intermediate profile which is received by a threshold base body 34, which also carries a guide rail 36 along which the movable leaf 12 can be moved, see also Fig. 3b, which shows the sliding door system 10 before the installation of the fixed field leaf 14.

[0027] Although the two seals 24 rest on the surface 32 of the sill profile 30, the weight of the fixed panel sash 14 is largely transferred to the sill profile 30 and from there into the sill base body 34 via an adapter assembly received by the fitting groove 26. The adapter assembly consists of an adapter part 40 and a compensating plate 42 (see also Fig. 4), whereby in the embodiment shown here, the adapter part 40 is detachably connected to the sill profile 30. For this purpose, pairs of locking feet 44 are formed on the underside of the adapter part 40, spaced apart from one another in the longitudinal direction thereof, which engage behind undercut sections provided along the side walls of a groove 46 formed in the sill profile 30 (see Fig. 2).The groove 46 in question extends from the groove base 48 of a receiving groove 50 formed in the surface 32, which positively receives a widened base section 52 of the adapter part 40. However, the adapter part 40 can also be formed integrally with the threshold profile 30.

[0028] Since the height dimension of the adapter part 40 above the surface 32 of the sill profile 30 is too small, this would result, without further precautions, in the lower horizontal frame profile leg 20 resting directly on the surface 32 of the sill profile 30. To prevent this, the adapter arrangement comprises the previously mentioned compensating plate 42, which is provided on the surface of the adapter part 40 serving as the mounting surface 54, in order to bridge the distance between the mounting surface 54 of the adapter part 40 and the groove base 28. The lower horizontal frame profile leg 20 thus rests above the groove base 28 of the fitting groove 26 on the compensating plate 42, which in turn is fastened to the mounting surface 54 of the adapter part 40. The weight from the fixed panel sash 14 is thus transferred in the desired manner via the adapter arrangement to the sill profile 30.

[0029] To prevent the compensating plate 42 from slipping off the adapter part 40 when the fixed field sash 14 is placed with its lower frame profile leg 20 onto the adapter arrangement, the embodiment of the adapter arrangement shown in Fig. 4 provides for the compensating plate 42 to be connected to the adapter part 40 by means of a locking mechanism. In the embodiment shown here, this mechanism comprises two pairs of tabs 56 that extend from an underside of the compensating plate 42 facing the mounting surface 54, with a barb 58 being formed at the free end of each of these tabs 56. The two tabs 56 of each pair of tabs are arranged symmetrically with respect to the longitudinal axis of the compensating plate 42, although due to the perspective view, only one tab of each pair of tabs can be seen in Fig. 4.

[0030] As can further be seen from Fig. 4, a plurality of openings 60 are formed in the mounting surface 54 of the adapter part 40, into which the four tabs 56 of the compensating plate 42 can be locked. The openings 60 are each delimited by an edge portion 62, wherein each of these edge portions 62 forms an undercut portion that can be engaged by the respective barb 58 of the respective tab 56, thereby locking the compensating plate 42 to the adapter part 40.

[0031] As can further be seen from Fig. 3, a plurality of inspection openings 64 are formed in the side surface of the adapter part 40, through which undercut areas formed by the edge sections 62 are accessible, for example by means of a screwdriver, in order to be able to release the locking of the barbs 58.

[0032] As can further be seen from Fig. 4, a first pair of tabs 66 is spaced a shorter distance from the first end 70 of the compensating plate 42 than a second pair of tabs 68 is spaced from the second end 72 of the compensating plate 42. Specifically, the first pair of tabs 66 is at a first distance from the first end 70 of the compensating plate 42, and the second pair of tabs 68 is at a second distance from the second end 72 of the compensating plate 42, which second distance is greater than the first distance. In order to nevertheless be able to attach the compensating plate 42 to the adapter part 40 both in the orientation shown and in an orientation rotated by 180°, a total of four pairs of openings 74, 75, 76, 77 are formed in the mounting surface 54 to accommodate the respective pairs of tabs.A first pair of openings 74 is spaced at the first distance from the first end 78 of the mounting surface 54, whereas a second pair of openings 75 is spaced at the second distance from the first end 78 of the mounting surface 54. Similarly, a third pair of openings 76 is spaced at the first distance from the second end 80 of the adapter part 40, whereas a fourth pair of openings 77 is spaced at the second distance from the second end 80 of the adapter part 40. This dimensioning allows the compensating plate 42 to be releasably locked to the mounting surface 54 of the adapter part 40 in two orientations rotated by 180°.This may prove to be particularly advantageous if the length of the compensating plate 42 between its first and second ends 70, 72 is the same as the length of the adapter part 40 between the first and second ends 78, 80 of the mounting surface 54, since in this case the compensating plate 42 can be fastened to the adapter part 40 substantially congruent with the mounting surface 54, regardless of its orientation.

[0033] Although the compensating plate 42 can be detachably connected to the adapter part 40 in the manner described above by means of the locking mechanism, since the compensating plate 42 is designed as a ribbed plate according to the illustration in Fig. 4, the ribs 82 of which define a plurality of partially circular or oval through-openings 84, it is possible to connect the compensating plate 42 to the adapter part 40 alternatively or in addition to the described locking connection by means of screws passed through the through-openings 84 in question.
