Description

[0001] The present invention relates to a universal adapter part with which connecting rods with different cross-sections or with different cross-sectional geometries can be connected to a carriage of a lift-and-slide element such as a lift-and-slide door or a lift-and-slide window.

[0002] As is well known, lift-and-slide elements can be moved from a lowered position, in which the element is fixed, to a raised position, in which it can be moved along a guide rail on the floor. To enable such a lift-and-slide element to be moved from its raised position to its lowered position and vice versa, these elements typically feature a fitting with a drive rod assembly. This assembly effectively connects the operating lever of the lift-and-slide element to a lifting mechanism for raising and lowering it. The movement of the operating lever is thus transmitted via the drive rod assembly to the lifting mechanism, allowing the lift-and-slide element to be raised or lowered as needed.

[0003] The lifting device in question, used for raising and lowering the lifting and sliding element, is typically part of a so-called carriage, which is concealed within a receiving groove formed on the underside of the lifting and sliding element. More precisely, the receiving groove on the underside of such a lifting and sliding element usually contains two or more carriages, which support the lifting and sliding element on the floor-side guide rail.Accordingly, the carriages arranged in the receiving groove of the lifting-sliding element must be coupled to each other in a drive-effective manner so that the actuating movement originating from the actuating lever, which is transmitted from the actuating lever via the connecting rod arrangement to a carriage and in particular its lifting device, can be transmitted simultaneously to all other carriages and in particular their lifting devices, so that the lifting-sliding element can be raised evenly without tilting.

[0004] For coupling the individual carriages of a lift-and-slide element, different connecting rods with varying cross-sectional geometries are typically used, depending on the profile of the respective sash. Depending on the cross-sectional geometry of the respective connecting rod, different measures must be taken to connect or couple the rod to its carriage at both ends. Since connecting rods with circular or square cross-sections, or rectangular cross-sections with sides of different lengths, are typically used to couple two carriages, at least two different connecting elements must usually be available to connect the respective connecting rod to the carriage. Because the rectangular cross-section connecting rods are installed vertically or horizontally depending on the sash profile,Since the connecting rods are to be installed in an upright or horizontal / flat orientation, three different connecting elements must generally be provided to accommodate the respective connecting rod ends. DE 203 16 289 U1 discloses a connecting element for accommodating connecting rods with a circular or square cross-section. DE 10 2018 114997 A1 discloses a connecting element for accommodating rectangular connecting rods of different orientations.

[0005] The invention is therefore based on the objective of creating a universally usable adapter part by means of which, depending on requirements, connecting rods with different cross-sectional geometries, in particular with circular or square cross-sections or with rectangular cross-sections, can be coupled to the carriage of a lifting-sliding element in different orientations.

[0006] This problem is solved with an adapter part having the features of claim 1 and in particular by the fact that the at least one receiving channel, viewed in cross-section, has a circular or square first channel section for receiving an end of the first connecting rod and a rectangular second channel section for receiving an end of the second connecting rod in a first orientation of the second connecting rod, as well as a rectangular third channel section tilted or inclined relative to the rectangular second channel section for receiving the end of the second connecting rod in a second orientation of the second connecting rod, in which the second connecting rod is tilted or inclined relative to the first orientation, preferably by 90°.

[0007] According to the invention, the adapter part has at least three channel sections with different cross-sectional geometries for receiving the respective connecting rods. Preferably, the three channel sections lie in a plane with respect to which they are mirror-symmetrical. The first channel section has a round or square cross-sectional geometry that is complementary to the cross-section of a connecting rod with a circular or square cross-section. The second channel section, on the other hand, has a rectangular cross-sectional geometry that is complementary to the cross-section of a connecting rod with a rectangular cross-section. The third channel section also has a rectangular cross-sectional geometry that is complementary to the cross-section of the rectangular connecting rod; however, the third channel section is tilted relative to the second channel section.The channels are inclined, specifically by 90°. For example, the second channel section, when the adapter is installed, can be oriented vertically or upright, whereas the third channel section can be tilted 90° relative to the second channel section and thus be oriented horizontally or flat. Depending on the profile geometry of the sash of the respective lift-and-slide element, connecting rods with a rectangular cross-section can be inserted into the second and third channel sections in different orientations and received by the adapter.

[0008] Since the universal adapter part according to the invention allows coupling rods with different cross-sectional geometries and orientations to be connected to a carriage of a lift-and-slide element, it is unnecessary to provide different connecting elements. Instead, the carriages can be equipped with the adapter part according to the invention at the factory. Because a coupling rod with a different cross-sectional geometry is required during the final assembly of a lift-and-slide element depending on the sash profile, no different connecting parts are needed during final assembly to connect the respective coupling rod to the carriage. Rather, the most common coupling rods can be inserted into the channel sections of the adapter part according to the invention, so that no different connecting parts need to be kept on hand during final assembly.

[0009] Preferred embodiments of the invention will now be discussed; further embodiments may also be apparent from the dependent claims, the description of the figures and the figures themselves.

[0010] While it is generally possible to design the three channel sections so that they merge seamlessly and thus together form a single receiving channel in the adapter part, a preferred embodiment provides for the adapter part to comprise two receiving channels separated by a partition. In other words, the at least one receiving channel can comprise a first receiving channel and a second receiving channel separated from it by a partition. The round or square first channel section can correspond to or form the first receiving channel, and the rectangular second channel section, together with the rectangular third channel section, can correspond to or form the second receiving channel.

[0011] For example, the rectangular second channel section can intersect or cross the rectangular third channel section, particularly at an angle of 90°. The rectangular second channel section can, for instance, transition into the rectangular third channel section at one of its two ends, so that the two rectangular channel sections together form the second receiving channel. The rectangular second channel section can have a vertical orientation, and the rectangular third channel section can have a horizontal orientation, such that the second receiving channel has a cross-sectional geometry corresponding to the shape of the capital letter "T", where, however, the "T" is preferably upside down or rotated by 180° when the adapter part is installed.

[0012] If, as explained above, the second receiving channel has the cross-sectional shape of an inverted "T", then the first channel section, when the adapter is installed, may be located closer to the rectangular second channel section than to the rectangular third channel section. In other words, in this case, the round or square first channel section may be further from the end of the rectangular second channel section where it transitions into the rectangular third channel section than from the opposite end of the rectangular second channel section. When installed, or...In the position of the adapter part attached to a carriage, the first channel section and thus the first receiving channel is located above the second receiving channel, which is composed of the rectangular second channel section and the rectangular third channel section and has a cross-sectional shape that corresponds to an upside-down "T".

[0013] If, however, the three channel sections each form a separate receiving channel, then, for example, the rectangular second channel section can be located between the round or square first channel section and the rectangular third channel section. The same applies to the embodiment in which the rectangular second channel section transitions into the rectangular third channel section at one end; in this case, too, the rectangular second channel section can be located between the round or square first channel section and the rectangular third channel section. To be more precise, the rectangular second channel section is located here largely or entirely within the third channel section.for the most part between the round or square first channel section and the rectangular third channel section, since in this embodiment the area of ​​the second channel section which it shares with the rectangular third channel section is not located between the first channel section and the rectangular third channel section, but in the area of ​​the rectangular third channel section.

[0014] To secure a connecting rod inserted into the vertically or upright rectangular second channel section, the adapter part can have two coaxially aligned through-openings that open into the rectangular second channel section. Preferably, the axis with respect to which the through-openings are coaxially aligned is perpendicular to the plane with respect to which the three channel sections are mirror images of each other. To secure a connecting rod inserted into the rectangular second channel section, a locking pin can, for example, be pressed into the through-openings, which then extends through an opening formed in the connecting rod, thereby firmly connecting the connecting rod to the adapter part and, via the adapter part, to the carriage on which the adapter part is mounted.Alternatively, a connecting rod inserted into the rectangular second channel section can also be secured therein by inserting a screw through the two through-holes and tightening it with a nut.

[0015] According to yet another embodiment, the adapter part can have at least one opening with an internal thread that leads into the rectangular third channel section. To secure a connecting rod inserted into the rectangular third channel section, a threaded pin or setscrew can be screwed into the threaded opening of the adapter part, thus clamping the end of the connecting rod inserted into the adapter part by means of the threaded pin.

[0016] Even if the rectangular second channel section transitions into the rectangular third channel section at one end, a connecting rod inserted into the rectangular second channel section can be clamped in place by screwing a threaded stud into the threaded opening. In this case, it is only necessary to ensure that the axis of the threaded opening lies in the same plane with respect to which the three channel sections are mirror images of each other.

[0017] According to yet another embodiment, at least one further through-opening can be formed in the partition wall, which may separate the round or square first channel section from the rectangular second channel section. This through-opening is aligned coaxially with the at least one threaded opening that leads into the rectangular third channel section. If, in this case, a correspondingly long threaded pin is screwed into the at least one threaded opening, it can extend through the through-opening in the partition wall into the round or square first channel section, in order to clamp a round or square connecting rod received by the round or square first channel section in place by means of the threaded pin.

[0018] In order to connect the adapter part to a carriage, the adapter part, according to a further embodiment, can have a coupling device at one end opposite the end to which the at least one receiving channel is open. This coupling device can, for example, be a through-hole through which a hinge pin can be inserted and pressed into place, thus enabling the adapter part to be pivoted to the side walls of a carriage. Since the coupling device is located at the end of the adapter part and therefore not in the area of ​​the channel sections, sufficient space is available at this point on the adapter part to form the two previously mentioned coaxially aligned through-holes that open into the rectangular second channel section.

[0019] Alternatively, the coupling device could, for example, be a cylindrical hinge pin that is integrally formed with the adapter part and projects from it on both sides. The adapter part can thus be articulated to the side plates of a carriage by inserting the cylindrical hinge pin into corresponding receiving openings at the ends of the side plates. The adapter part is therefore articulated to the side plates of the carriage and can thus compensate for any unevenness in the ground that the carriage encounters.

[0020] The invention will now be described in the following by way of example only, with reference to the drawings in which: Fig. 1 shows a perspective view of an adapter part according to the invention on a carriage that is only partially shown, but which is, however, in the Fig. 2is fully recognizable; and Figs. 2 to 5 illustrate the coupling of connecting rods with different cross-sectional geometry and different orientations with the carriage.

[0021] The following will first refer to the Fig. 2 The basic structure and operation of a carriage 10 with an integrated lifting device 12 are explained. The carriage 10 has two rollers 14, which are arranged between two parallel side walls 16 and are rotatably mounted on them. Furthermore, the carriage 10 has a base element 18 that can be attached to the underside of a wing (not shown), in which a guide track 20 is formed in the form of an obliquely oriented slot. An axle 22 extends through this slot and is attached to the two side walls 16.

[0022] If the operating lever (not shown) of the stationary sash is turned, this rotational movement is transmitted via a connecting rod arrangement (also not shown) and a deflection device 24 of the carriage 10 to the two side plates 16 of the carriage 10, causing the carriage to be moved horizontally while the sash remains stationary. This, in turn, changes the position of the axis 22 within the inclined guide track 20, allowing the sash, supported by the base part 18, to be raised or lowered as desired.

[0023] In order to transfer the previously described horizontal movement of the side panels 16 to a further carriage provided on the underside of the wing, it is necessary to connect the two carriages to each other with a connecting rod 28 in a drive-effective manner. For this purpose, the adapter part 26 according to the invention is used, which in turn is coupled to the carriages at the ends of the side panels 16, in particular by means of a pivot. Therefore, the following will now refer to the Fig. 1 The adapter part 26 according to the invention is described in more detail.

[0024] The adapter part 26 is a one-piece or monolithic component in which a first receiving channel 30 and a second receiving channel 32 are formed, which extend essentially parallel to each other and are open towards a first end 34 of the adapter part 26. The first receiving channel 30 is located above the second receiving channel 32, with "above" referring to the installed state.

[0025] In the embodiment shown here, the first receiving channel 30 is separated from the second receiving channel 32 by an intermediate wall 46. Alternatively, the two receiving channels 30, 32 can also merge into one another.

[0026] In the embodiment shown here, the first receiving channel 30 is formed by a first, circular channel section 40. The first, circular channel section 40 thus corresponds to the first receiving channel 30. Furthermore, in the embodiment shown here, the second receiving channel 32, viewed in cross-section, has a vertically oriented channel section 36 with a rectangular cross-sectional shape and a horizontally or flatly oriented channel section 38, also with a rectangular cross-sectional shape. The two channel sections 36, 38 are therefore perpendicular to each other, with the vertically or uprightly oriented channel section 36 transitioning into the horizontally oriented channel section 38 at its lower end. Similarly, the vertically oriented channel section 36 could also transition into the first receiving channel 30 at its opposite end or at its top.In this case, the adapter part 26 according to the invention would only have a single receiving channel, as already mentioned above.

[0027] Due to the fact that the vertically or upright oriented channel section 36 transitions at its lower end into the horizontally oriented channel section 38, the second receiving channel 32 has the shape of an upside-down "T" when viewed in cross-section.

[0028] The entire adapter part 26 is designed in a mirror-symmetrical manner with respect to a central plane in which the three channel sections 36, 38, 40 lie, which means that the three channel sections 36, 38, 40 are also designed in a mirror-symmetrical manner with respect to the central plane in question.

[0029] Again Fig. 1 Furthermore, it can be seen that the adapter part 26 has two coaxially arranged through-openings 42, of which, due to the perspective of the Fig. 2However, only one through-opening 42 is visible. The two through-openings 42 open into the vertically or upright oriented channel section 36 with a rectangular cross-sectional shape. The axis with respect to which the two through-openings 42 are coaxial is oriented perpendicular to the central plane with respect to which the three channel sections 36, 38, 40 are mirror-symmetrical.

[0030] Furthermore, the adapter part 26 according to the invention has two threaded openings 44 on its underside, which open into the horizontally or flatly oriented channel section 38 with a rectangular cross-sectional shape. Although this is not apparent from the figures, two through-openings are formed in the intermediate wall 46, each of which is aligned coaxially with the threaded openings 44 on the underside of the adapter part 26. The two through-openings thus connect the vertically oriented channel section 36 with a rectangular cross-sectional shape to the round channel section 40, or the first receiving channel 30 to the second receiving channel 32.

[0031] In order to pivot the adapter part 26 to the side walls 16 of a carriage 10, the adapter part 26 has a coupling device at its second end 35, which is opposite the first end 34, towards which the receiving channels 30, 32 are open, in the form of two cylindrical hinge pins 48, the axis of which runs perpendicular to the central plane with respect to which the adapter part 26 is mirror-symmetrical. The hinge pins 48 can thus be received by through openings 52 provided at the ends of the two side walls 16 of a carriage 10, in order to pivotally couple the adapter part 26 to the side walls 16 of the carriage 10.

[0032] If, for example, it is desired to connect a connecting rod 28 with a rectangular cross-section in a standing or vertical orientation to the carriage 10 via the adapter part 26, the connecting rod 28 can be connected according to the Fig. 2 or 4into the vertically or upright oriented channel section 36 with rectangular cross-sectional shape and inserted therein either according to Fig. 2 secured with a pin 50, which is inserted through the through-openings 42 and a through-hole formed at one free end of the connecting rod 28. Alternatively, the connecting rod 28 can be secured according to Fig. 4 The adapter part 26 is clamped in the vertically oriented channel section 36 using two threaded pins 54, for which purpose the threaded pins 54 are screwed into the threaded openings 44 on the underside of the adapter part 26.

[0033] If, however, it is desired to connect a connecting rod 28 with a rectangular cross-section in a horizontal or flat orientation to the carriage 10 via the adapter part 26, this is also possible without further preparations. For this purpose, the connecting rod 28 is attached according to Fig. 3in a horizontal or flat orientation into the horizontally or flatly oriented channel section 38 of the second receiving channel 32 and clamped in it by means of the threaded pins 54.

[0034] A connecting rod 28 with a round cross-section can also be connected to the carriage 10 via the adapter part 26 without any further preparations. For this purpose, the connecting rod 28 with a round cross-section is connected according to... Fig. 5The components are inserted into the round channel section 40, or into the first receiving channel 30 formed therein, and clamped in the round channel section 40 by means of threaded pins 56, which are longer than the threaded pins 54. The threaded pins 56 extend through the two threaded openings 44 on the underside of the adapter part 26, the vertically oriented channel section 36, and the through-openings formed in the intermediate wall 46 that separate the first receiving channel 30 from the second receiving channel 32.

[0035] By means of the adapter part 26 according to the invention, not only can connecting rods with different cross-sectional geometries and orientations be connected to the carriage 10; rather, the adapter part 26 also offers great flexibility with regard to the length of the connecting rods 28, since these can be shortened on site to the desired length due to the fact that they can be clamped to the adapter part 26.
