Abstract
Description
Technical Field
[0001] The invention relates to a universal adapter for connecting coupling rods with different cross sections or different cross-sectional geometries to a carriage of a lift-sliding element, such as a lift-sliding door or lift-sliding window. Background Art
[0002] As is known, a lifting slide element can be transferred from a lowered position, in which the lifting slide element is immovable, to a raised position, in which the lifting slide element can be moved along the bottom guide rail. In order to be able to transfer such a lifting slide element from its raised position to its lowered position or vice versa, such a lifting slide element usually has a fitting with a transmission rod arrangement, via which an actuating rod of the lifting slide element is actively coupled to a lifting device of the lifting slide element in order to raise and lower it. The movement of the actuating rod is thus transmitted to the lifting device via the transmission rod arrangement, so that the lifting slide element can be raised or lowered as required.
[0003] The lifting device for lifting and lowering the lifting slide element is usually part of a so-called carriage, which is concealed in a receiving groove formed on the underside of the lifting slide element. More precisely, in the receiving groove at the underside of such a lifting slide element there are usually two or more carriages, by means of which the lifting slide element stands on the bottom rail. Accordingly, the carriages arranged in the receiving groove of the lifting slide element must be coupled to each other in an operatively driving manner so that an actuating movement issued by the actuating rod and transmitted from the actuating rod via the transmission rod device to a carriage, in particular its lifting device, can be transmitted simultaneously to all other carriages, in particular their lifting devices, so that the lifting slide element can be lifted uniformly without tilting.
[0004] To connect the individual carriages of the lifting and sliding element, different connecting rods or coupling rods with different cross-sectional geometries are usually used, depending on the contour of the respective wing. Therefore, depending on the cross-sectional geometry of the respective coupling rod, different measures must be taken in order to be able to fasten the two ends of the respective coupling rod to the respective carriage or to couple it thereto.
[0005] Since the connection of two carriages usually uses connecting rods with a circular or square cross section or connecting rods with a rectangular cross section, which have sides of different lengths, it is usually necessary to provide at least two different connecting elements, by which the corresponding connecting rod can be connected to the carriage. Since the connecting rod with a rectangular cross section is here mounted in a vertical or upright orientation or in a horizontal or lying orientation depending on the wing profile, it is usually even necessary to provide three different connecting elements to receive the corresponding connecting rod ends. Summary of the invention
[0006] The object of the present invention is therefore to provide a universal adapter, by means of which coupling rods with different cross-sectional geometries, in particular with a circular or square cross section or with a rectangular cross section, can be connected to the carriage of a lifting and sliding element in different directions as required.
[0007] The object of the present invention is achieved by an adapter having the features of claim 1 and in particular in that, viewed along a cross section, at least one receiving channel has a circular or square first channel section for receiving an end of a first connecting rod, a rectangular second channel section for receiving an end of a second connecting rod along a first direction of the second connecting rod, and a rectangular third channel section, which is inclined or tilted relative to the rectangular second channel section to receive the end of the second connecting rod along a second direction of the second connecting rod, and the second connecting rod is inclined or tilted relative to the first direction along the second direction and is preferably inclined or tilted 90°.
[0008] Therefore, the adapter according to the present invention has at least three channel sections, which have different cross-sectional geometries for receiving corresponding connecting rods. Preferably, the three channel sections can be located in a plane, and the three channel sections are mirror-symmetrical about the plane. Here, the first channel section has a circular or square cross-sectional geometry, which is constructed to be complementary to the cross-section of the connecting rod with a circular or square cross section. On the other hand, the second channel section has a rectangular cross-sectional geometry, which is constructed to be complementary to the cross-section of the connecting rod with a rectangular cross section. The third channel section also has a rectangular cross-sectional geometry, which is constructed to be complementary to the cross-section of the rectangular connecting rod; however, the third channel section is inclined or tilted relative to the second channel section, and is particularly inclined or tilted by 90°. For example, the second channel section can be oriented vertically or vertically in the installed state of the adapter, while the third channel section can be inclined by 90° relative to the second channel section and is therefore oriented horizontally or lying flat. Thus, depending on the contour geometry of the wing of the respective lifting and sliding element, a coupling rod with a rectangular cross section can be introduced into the second or third channel section in different directions and received by the adapter.
[0009] Since the universal adapter according to the invention makes it possible to connect coupling rods with different cross-sectional geometries and in different orientations to the carriage of the lifting and sliding element, it is no longer necessary to provide different connecting elements. Instead, the carriage can be equipped with the adapter according to the invention already at the factory stage. Since coupling rods with different cross-sectional geometries are required during the final assembly of the lifting and sliding element depending on the wing profile, different connecting pieces are no longer required during the final assembly in order to be able to connect the corresponding coupling rods to the carriage. Instead, the most common coupling rods can be inserted into the channel section of the adapter according to the invention, so that different connecting pieces do not need to be prepared in advance during the final assembly.
[0010] Preferred embodiments of the invention will be discussed below; further embodiments may be derived from the dependent claims, the description of the figures and the figures themselves.
[0011] Although in principle the three channel sections can be configured to intersect with each other and thus form a single receiving channel together in the adapter, according to a preferred embodiment, the adapter can include two receiving channels separated from each other by an intermediate wall. In other words, at least one receiving channel can include a first receiving channel and a second receiving channel separated from the first receiving channel by an intermediate wall. Here, the circular or square first channel section can correspond to the first receiving channel or form the first receiving channel, and the rectangular second channel section can correspond to the second receiving channel or form the second receiving channel together with the rectangular third channel section.
[0012] For example, the rectangular second channel section can intersect or cross the rectangular third channel section, more precisely, in particular at an angle of 90°. Thus, for example, the rectangular second channel section can transition to the rectangular third channel section at one of its two ends, so that the two rectangular channel sections together form the second receiving channel. In this case, the rectangular second channel section can have a vertical or upright orientation, and the rectangular third channel section can have a horizontal or lying orientation, so that the second receiving channel has a cross-sectional geometry that corresponds to the shape of the capital letter "T", wherein the "T" is preferably inverted or rotated 180° in the installed state of the adapter.
[0013] If the second receiving channel has an inverted "T" shape when viewed in cross section as described above, the first channel section can be closer to the rectangular second channel section than the rectangular third channel section in the installed state of the adapter. In other words, in this case, the round or square first channel section can be farther from the end of the rectangular second channel section where the round or square first channel section transitions to the rectangular third channel section than the opposite end of the rectangular second channel section. Therefore, in the installed state of the adapter or in the state fastened to the carriage, the first channel section and therefore the first receiving channel are 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 corresponding to the inverted "T".
[0014] If, on the other hand, the three channel sections each form a separate receiving channel, the rectangular second channel section can be located, for example, between the circular or square first channel section and the rectangular third channel section. The same applies to embodiments in which the rectangular second channel section transitions into the rectangular third channel section at one end; in this case, the rectangular second channel section can be located between the circular or square first channel section and the rectangular third channel section. More precisely, the rectangular second channel section is here mostly or almost mostly located between the circular or square first channel section and the rectangular third channel section, because in this embodiment, the area of the second channel section shared 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.
[0015] In order to enable the coupling rod introduced into the second rectangular channel section of vertical or vertical orientation to be fixed therein, the adapter may have two coaxially oriented channel openings, which lead into the second rectangular channel section. Preferably, it can be provided that the axis of coaxially oriented channel openings is perpendicular to the plane of mirror symmetry of the three channel sections. Therefore, in order to enable the coupling rod introduced into the second rectangular channel section to be fixed therein, for example, a fixing pin can be pressed into the channel opening, which then extends through the opening formed in the coupling rod, whereby the coupling rod is fixedly connected to the adapter and connected to the slide on which the adapter is provided via the adapter. Alternatively, the coupling rod introduced into the second rectangular channel section can also be fixed therein by inserting a bolt through the two channel openings and tightening it with a nut.
[0016] According to another embodiment, the adapter may have at least one opening formed with an internal thread, which opens into the rectangular third channel section. In order to fix the coupling rod introduced into the rectangular third channel section, a threaded pin or a countersunk screw may be screwed into the threaded opening of the adapter so that the end of the coupling rod introduced into the adapter can be clamped therein by means of the threaded pin.
[0017] Similarly, when one end of the rectangular second channel section transitions into the rectangular third channel section, the coupling rod introduced into the rectangular second channel section can also be clamped therein by screwing a threaded pin into the threaded opening. In this case, it is only necessary to ensure that the axis of the threaded opening is located in the same plane that makes the three channel sections mirror-symmetrical.
[0018] According to a further embodiment, at least one further passage opening can be formed in the intermediate wall separating the circular or square first passage section from the rectangular second passage section, which passage opening is oriented coaxially with the at least one threaded opening leading into the rectangular third passage section. If in this case a correspondingly long threaded pin is screwed into the at least one threaded opening, the threaded pin can extend through the passage opening in the intermediate wall into the circular or square first passage section, so that a circular or square coupling rod received by the circular or square first passage section can be clamped therein by means of the threaded pin.
[0019] According to another embodiment, in order to be able to connect the adapter to the carriage, the adapter can be provided with a coupling device for coupling to the carriage at one end, which is opposite the end toward which the at least one receiving channel is open. The coupling device can be, for example, a channel opening through which a hinge pin can be inserted and pressed in, so that the adapter can be hinged to the side wall of the carriage. Since the coupling device is located at the end of the adapter and not in the region of the channel section, there is enough space at this point on the adapter to form the above-mentioned two coaxially oriented channel openings, which open into the rectangular second channel section.
[0020] As an alternative to this, the coupling device can be, for example, a cylindrical hinge pin which is formed integrally with the adapter and protrudes from the adapter on both sides. The adapter can thus be connected in an articulated manner to the side wall of the carriage, wherein the cylindrical hinge pin is arranged in a corresponding receiving opening at the end of the side wall. The adapter is thus connected in an articulated manner to the side wall of the carriage and can thus compensate for any ground irregularities encountered by the carriage. BRIEF DESCRIPTION OF THE DRAWINGS
[0021] The present invention will be described purely exemplarily below with reference to the accompanying drawings, in which:
[0022] Figure 1 A perspective view of an adapter according to the invention is shown on a carriage which is only partially shown, but in Figure 2 can see them all in
[0023] Figures 2 to 5 Couplings of coupling rods to carriages with different cross-sectional geometries and different orientations are shown. DETAILED DESCRIPTION
[0024] Please refer to the following Figure 2 The basic structure of a carriage 10 with an integrated lifting device 12 and its mode of operation are explained. The carriage 10 has two rollers 14, which are arranged between two side walls 16 extending parallel to each other and are rotatably mounted thereon. The carriage 10 also has a base element 18 that can be attached to the underside of a wing (not shown), in which an obliquely oriented slot-like guide chute 20 is formed. A shaft 22 extends through the slot, which shaft is fastened to the two side walls 16.
[0025] If the actuating lever (not shown) is turned while the wing is fixed, this rotational movement is transmitted via the transmission lever device (also not shown) and via the deflection device 24 of the carriage 10 to the two side walls 16 of the carriage 10, which causes the side walls to be displaced in the horizontal direction when the wing is fixed. This in turn causes the position of the shaft 22 inside the inclined guide chute 20 to change, so that the wing supported on the base element 18 can be raised or lowered in the desired manner.
[0026] In order to be able to transmit the aforementioned horizontal movement of the side wall 16 to the other carriage arranged at the lower side of the wing, it is necessary to connect the two carriages to each other in a drivingly effective manner with the coupling rod 28. For this purpose, an adapter 26 according to the invention is used, which is connected to the carriage at the end of the side wall 16 and is in particular connected in an articulated manner. Therefore, in the following, reference will be made to Figure 1 The adapter 26 according to the present invention will be described in more detail.
[0027] The adapter 26 is a one-piece or integral component, in which a first receiving channel 30 and a second receiving channel 32 are formed, which extend substantially parallel to each other and are open toward a first end 34 of the adapter 26. Here, the first receiving channel 30 is located above the second receiving channel 32, where "above" means in the installed state.
[0028] In the embodiment shown here, the first receiving channel 30 is separated from the second receiving channel 32 by an intermediate wall 46. As an alternative to this, however, the two receiving channels 30, 32 can also merge with one another.
[0029] In the embodiment shown here, the first receiving channel 30 is formed by a circular first channel section 40. This circular first channel section 40 therefore 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 horizontally oriented channel section 38 (with a likewise rectangular cross-sectional shape). The two channel sections 36, 38 therefore extend at right angles to one another, wherein the vertically or vertically oriented channel section 36 transitions at its lower end into the horizontally oriented channel section 38. Accordingly, the vertically oriented channel section 36 can also transition into the first receiving channel 30 at its opposite end or at the top. In this case, the adapter 26 according to the invention would, as described above, have only a single receiving channel.
[0030] Since the vertically or uprightly oriented channel section 36 merges at its lower end into the horizontally oriented channel section 38 , the second receiving channel 32 has an inverted “T” shape when viewed in cross section.
[0031] The entire adapter piece 26 is mirror-symmetrical with respect to a central plane in which the three channel sections 36 , 38 , 40 are located, which means that the three channel sections 36 , 38 , 40 are also designed to be mirror-symmetrical with respect to the central plane.
[0032] In addition, Figure 1 As shown, the adapter 26 has two passage openings 42 arranged coaxially with each other, but due to Figure 2 From a viewing angle, only one of the passage openings 42 can be seen. The two passage openings 42 here open into a vertical or vertically oriented passage section 36 with a rectangular cross-sectional shape. The coaxial axes of the two passage openings 42 are oriented perpendicularly to the central plane, about which the three passage sections 36, 38, 40 are mirror-symmetrical.
[0033] Furthermore, the adapter 26 according to the invention has two threaded openings 44 on its underside, which open into the horizontally or lying channel section 38 with a rectangular cross-sectional shape. Although it cannot be seen from the figures, two channel openings are formed in the intermediate wall 46, which are coaxially aligned with the threaded openings 44 on the underside of the adapter 26. The two channel openings thus connect the vertical channel section 36 with a rectangular cross-sectional shape to the circular channel section 40, or the first receiving channel 30 to the second receiving channel 32.
[0034] In order to be able to articulate the adapter 26 to the side wall 16 of the carriage 10, the adapter 26 has two coupling means in the form of cylindrical hinge pins 48 at its second end 35, which is opposite to the first end 34 (to which the receiving channels 30, 32 are open), the axes of which extend perpendicularly to the mirror-symmetrical center plane of the adapter 26. Therefore, the hinge pins 48 can be received by the channel openings 52 provided at the ends of the two side walls 16 of the carriage 10, so that the adapter 26 can be articulatedly connected to the side wall 16 of the carriage 10.
[0035] If, for example, it is now necessary to connect a coupling rod 28 having a rectangular cross section to the carriage 10 in the vertical or upright direction via the adapter 26, then for this purpose the coupling rod 28 can be connected in accordance with the embodiment of the present invention. Figure 2 or Figure 4 The connecting rod 28 is introduced into a vertically or vertically oriented channel section 36 with a rectangular cross-sectional shape and is connected therein according to Figure 2 The fixing is shown by means of a pin 50 which passes through the passage opening 42 and the passage hole forming the free end of the coupling rod 28. Figure 4 The coupling rod 28 can be clamped in the vertically oriented channel section 36 by means of two threaded pins 54 , for which purpose the threaded pins 54 are screwed into the threaded openings 44 on the underside of the adapter piece 26 .
[0036] On the other hand, if it is necessary to connect the coupling rod 28 with a rectangular cross section in a horizontal or horizontal direction via the adapter 26 to the carriage 10, this is also possible without further measures. Figure 3 As shown, the coupling rod 28 is introduced in the horizontal or lying direction into the horizontal or lying channel section 38 of the second receiving channel 32 and is clamped therein by means of a threaded pin 54 .
[0037] A coupling rod 28 with a circular cross section can also be connected to the carriage 10 via the adapter 26 without further measures. Figure 5 The adapter 26 is shown as being introduced into the circular channel section 40 or the first receiving channel 30 formed by the circular channel section and clamped in the circular channel section 40 by means of a threaded pin 56 which is longer than the threaded pin 54. The threaded pin 56 here extends through the two threaded openings 44 on the underside of the adapter 26, the vertically oriented channel section 36 and the channel opening formed in the intermediate wall 46 and separating the first receiving channel 30 from the second receiving channel 32.
[0038] Therefore, with the help of the adapter 26 according to the present invention, not only can connecting rods with different cross-sectional geometries and directions be connected to the slide 10; but the adapter 26 also provides great flexibility with respect to the length of the connecting rod 28, because the connecting rod can be clamped with the adapter 26 and can be shortened to the required length on site as needed.
