Description

Technical Field

[0001] This invention relates to an assembly attachment for a sliding element (e.g., a sliding door or a sliding window), the sliding element comprising a frame and a fan wing movable relative to the frame along a track in a direction of movement, wherein the assembly attachment comprises: at least one base configured to be fastened to the fan wing; at least one movable bracket having a movable bracket frame and at least two rollers mounted on the movable bracket frame; a lifting mechanism for raising the fan wing relative to the movable bracket frame from a lowered position to a raised position, wherein the lifting mechanism has an inclined guide via which the movable bracket frame is movably guided on the base in a direction inclined to the direction of movement; and a connecting lever having a first end connected to the movable bracket frame and a second end opposite to the first end, the second end being hinged to a steering lever hinged to the base, the lifting mechanism being actuated by means of a transmission rod via the connecting lever. Background Technology

[0002] The assembly accessory, essentially understood from patent document DE102018124778A1, is used for raising or lowering lifting sliding elements, such as the increasingly common large balcony doors or windows. In the installed lifting sliding element, the direction of movement is horizontal. Typically, multiple movable brackets are arranged on the underside of the fan blade, where rollers roll directly on the lower rail. In principle, one or more movable brackets can also be arranged on the upper side of the fan blade, where rollers are suspended in a suspension rail and roll within it. In this embodiment, the lower rail can be set to rest on the ground. Furthermore, the underside of the fan blade can be positioned on the rail in a lowered position. By actuating the lifting mechanism, the fan blade can be raised relative to the movable bracket frame, thereby creating an air gap between the rail and the movable bracket frame, allowing the fan blade to move via the rollers.

[0003] The movable bracket frame can be any load-bearing component used to support the rollers. That is, the movable bracket frame does not necessarily have to be constructed in a frame-like manner to have a closed shape; rather, the movable bracket frame can be formed, for example, by two flat irons spaced apart from each other, which are connected to each other by a spacer or by the rollers themselves.

[0004] The tilting guide of the lifting mechanism converts the horizontal adjustment movement of the moving bracket into the lifting movement of the fan blades, which is achieved, for example, through a transmission rod assembly and a steering lever. It should be noted that the term "tilt guide" is not necessarily understood as guidance with a straight tilting guide path. Rather, tilt guide should be understood as guidance whose guide path is neither parallel nor perpendicular to the direction of movement. That is, tilt guide can extend in a generally curved manner as long as an infinitesimal portion of the relevant guide path is tilted towards the direction of movement.

[0005] In practice, unfavorable forces may be applied to the moving bracket when raising and lowering the fan blades. In particular, uneven loading of the two rollers may occur. Therefore, due to the vertical force component transmitted to the moving bracket frame, the roller closer to the connecting lever (also referred to herein as the front roller) is less loaded, thus causing the other roller (also referred to herein as the rear roller) to be overloaded. This can lead to uneven wear and tear on the rollers, potentially causing significant changes in the sliding behavior of the lifting sliding element. This, in turn, may necessitate replacement of the moving bracket, which is costly for the end user. Summary of the Invention

[0006] Therefore, the object of the present invention is to provide an assembly attachment for lifting sliding elements, which is constructed to minimize wear and reduce maintenance costs.

[0007] The objective of the present invention is achieved by an assembly accessory.

[0008] According to the present invention, the first end of the connecting lever is connected to the movable bracket frame via a joint, which allows or enables relative movement in the transverse direction of movement between the first end of the connecting lever and the movable bracket frame.

[0009] That is, compared to a purely rotatable or hinged connection between the connecting lever and the movable bracket frame, this introduces additional degrees of freedom, particularly a degree of movement. This allows the movable bracket frame to compensate for any tilting posture it experiences during the raising or lowering of the fan blade due to the possible vertical force component on the connecting lever. For example, if the front end of the movable bracket frame bears a lifting force via the connecting lever during the fan blade raising, this tendency can be counteracted because the joint between the connecting lever and the movable bracket frame allows for relative movement in the lateral direction relative to the direction of movement between the first end of the connecting lever and the movable bracket frame due to the additional degree of movement freedom introduced into the joint.

[0010] Therefore, if the front end of the movable bracket frame tends to rise to a certain degree, the front end of the movable bracket frame can be lowered again to the same degree during the lifting process due to the additional degree of freedom introduced between the movable bracket frame and the connecting lever. Thus, during the lifting or lowering of the vane, the movable bracket frame will not tilt excessively, thereby preventing uneven loading on the rollers of the movable bracket. Therefore, by lowering the movable bracket frame at its front end to approximately the same degree as the degree it was raised at its front end during the vane lifting process, undesirable tilting of the movable bracket frame can be compensated for.

[0011] Any possible tilting attitude of the moving bracket frame can be taken into account during the lowering of the fan blades, so that there will be no uneven load on the rollers of the moving bracket even during the lowering movement.

[0012] Preferred embodiments of the present invention will now be discussed. Further embodiments can be derived from the following description, the accompanying drawings, and the drawings themselves.

[0013] According to one embodiment, the joint may be formed by an elongated hole formed in a movable bracket frame and a pin on a first end of a connecting lever, wherein the pin is movably guided in the elongated hole.

[0014] Alternatively, the joint can be formed by an elongated hole formed in the first end of the connecting lever and a pin on the movable bracket frame, wherein the pin is movably guided in the elongated hole.

[0015] Therefore, a compensating link (Ausgleichskulisse) is formed by guiding a pin in the elongated hole, which allows the first end of the connecting lever to move vertically relative to the front end of the movable bracket frame. This introduces an additional degree of freedom of movement in the vertical direction compared to a conventional rotary joint, allowing the front end of the movable bracket frame to move vertically relative to the first end of the connecting lever, thereby compensating for undesirable tilting attitudes of the movable bracket frame during raising or lowering of the fan blades in the aforementioned manner.

[0016] According to another embodiment, the connecting lever has a lug at its first end, in which an elongated hole is formed. The lug here has a wider width than at its second end. Therefore, although forming the elongated hole requires a certain size, the connecting lever can still be constructed to be relatively slender.

[0017] According to another embodiment, the tilting guide may include a guide groove (Führungskulisse) extending obliquely in the base relative to the direction of movement and a pin guided in the guide groove, the pin being positioned between two rollers on the movable bracket frame. This tilting guide not only reliably transfers the weight of the fan blade to the movable bracket frame; rather, it forms a joint through the pin movably guided in the guide groove, around which the fan blade can gradually rotate or tilt during lifting or lowering. In other words, the pin guided in the guide groove allows the movable bracket frame to gradually twist relative to the fan blade or base during lifting or lowering of the fan blade, in order to balance or compensate for undesirable tilting postures of the movable bracket frame.

[0018] The present invention also relates to a lifting sliding element, particularly a lifting sliding door or lifting sliding window, having a frame, a fan wing movable relative to the frame along a track in a direction of movement, and, particularly, an assembly attachment constructed according to the foregoing embodiments, wherein the assembly attachment includes: at least one base fastened to the fan wing; at least one movable bracket having a movable bracket frame and at least two rollers mounted on the movable bracket frame; a lifting mechanism for lifting the fan wing relative to the movable bracket frame from a lowered position to a raised position, wherein the lifting mechanism has an inclined guide through which the movable bracket frame is movably guided on the base in a direction inclined to the direction of movement; and a connecting lever having a first end connected to the movable bracket frame and a second end hinged to a steering lever hinged to the base, through which the lifting mechanism can be actuated by means of a transmission rod; wherein, according to the invention, the first end of the connecting lever is connected to the movable bracket frame by a joint that allows relative movement between the first end of the connecting lever and the movable bracket frame in a direction transverse to the direction of movement. Attached Figure Description

[0019] The invention is described below by way of example with reference to the accompanying drawings, in which:

[0020] Figure 1 A schematic side view of the assembly accessory according to the invention in a lowered initial state is shown;

[0021] Figure 2 It shows according to Figure 1 A cross-sectional view of the assembly accessories in their lowered initial state;

[0022] Figure 3 It shows according to Figure 2 A view of the assembled accessories in a partially raised state; and

[0023] Figure 4 It shows according to Figure 2 and Figure 3 The view of the assembled accessories in the fully raised state. Detailed Implementation

[0024] Figures 1 to 4 A portion of an assembly accessory 11 according to the invention is shown, which includes a base 13. The base 13 is designed for fastening to a (not shown) swashplate of a sliding door. In the illustrated embodiment, the base 13 is at least substantially L-shaped and thus used for direct fastening in the lower corner region of the swashplate, but this configuration is not mandatory. In principle, the base 13 can also be designed for indirect fastening to the swashplate.

[0025] To enable the fan blade to move along the horizontal direction of movement V, assembly accessory 11 includes a movable bracket 17 comprising a movable bracket frame 25 and two rollers 26 and 27 rotatably mounted on the movable bracket frame 25, namely, a front roller 26 and a rear roller 27. The rollers 26 and 27 roll on a track arranged below the fan blade as the fan blade moves, but this track is not shown here. Assembly accessory 11 can have one or more additional movable brackets in a manner known in principle to form a coupled movable bracket system, but this is not shown in the figures. The direction of movement V extends parallel to the longitudinal extension direction of the mounting surface 28 of the base 13, which corresponds to the underside of the fan blade.

[0026] To raise and lower the fan blades, assembly accessory 11 includes a lifting mechanism 30, which can be actuated by a drive rod 33, raising or lowering the base 13 relative to the movable bracket frame 25 according to the direction of movement of the drive rod 33. Here, the drive rod 33 is effectively driven to be connected to the movable bracket 17, and particularly to its movable bracket frame 25, via a steering lever 34 and a connecting lever 31. For this purpose, the drive rod 33 is hinged to the steering lever 34, which in turn is hinged to the front end of the base 13. The connecting lever 31 then connects the steering lever 34 to the movable bracket frame 25. For this purpose, the first end 21 of the connecting lever 31 is connected to the movable bracket frame 25 by a joint 19, which is described in detail below, allowing relative movement transverse to the direction of movement V between the first end 21 of the connecting lever 31 and the movable bracket frame 25. In contrast, the second end 23, opposite the first end of the connecting lever 31, is purely rotatably connected or hinged to the steering lever 34.

[0027] The lifting mechanism 30 also includes a tilting guide 35 for converting the horizontal movement of the movable bracket 17 caused by the movement of the drive rod into the vertical movement of the base 13. For this purpose, the tilting guide 35 includes a guide groove 38 formed on or within the base 13 and extending obliquely in the direction of movement V, and a load-bearing element in the form of a pin 36 arranged on the movable bracket frame 25 and guided in this guide groove. Here, the pin 36 is located between the front roller 26 and the rear roller 27. If the drive rod 33 is now actuated, its movement is converted via the steering lever 34 into a substantially horizontal movement of the connecting lever 31, which causes the movable bracket frame 25 and thus the pin 36 to move in the guide groove 38, thereby raising or lowering the movable bracket frame 25 relative to the base 13.

[0028] If now especially in the fan wing according to from Figure 2 via Figure 3 Then Figure 4 Observing the process from the perspective of elevation, it can be seen that the hinged position of the second end 23 of the connecting lever 31 on the steering lever 34 gradually moves upward relative to the pin 40 that fixes the first end 21 of the connecting lever 31 to the movable bracket frame 25. As a result, the tension F exerted by the connecting lever 31 on the movable bracket frame 25 includes a vertical force component F. v ,See Figure 4 The detail "C". When the first end 21 of the connecting lever 31 is purely hinged to the movable bracket frame 25, the vertical force component F... v This will cause the front end of the movable bracket frame 25 to be subjected to a lifting force during the fan-wing lifting process. This lifting force reduces the load on the front roller 26 and correspondingly causes the rear roller 27 to be additionally loaded, which in some cases may even cause the front roller 26 to rise off the track.

[0029] This results in uneven load and uneven wear on rollers 26 and 27, so it is desirable to ensure that the two rollers 26 and 27 always bear the load of the most similar intensity possible.

[0030] Therefore, according to the present invention, a vertical degree of freedom of movement is introduced at the connection point or joint 19 between the first end 21 of the connecting lever 31 and the movable bracket frame 25, which allows the front end of the movable bracket frame 25 to move relative to the first end 21 of the connecting lever 31 in a direction transverse to the direction of movement V. For this purpose, in the illustrated embodiment, a substantially vertically oriented elongated hole 42 can be constructed in the first end 21 of the connecting lever 31, in which a pin 40, provided at the front end of the movable bracket frame 25 and connecting the movable bracket frame 25 to the connecting lever 31, is movably guided. Alternatively, a substantially vertically formed elongated hole can also be provided in the front end of the movable bracket frame 25, in which a pin fastened to the first end 21 of the connecting lever 31 is movably guided in the vertical direction.

[0031] Therefore, if the fan wings are now based on from Figure 2 through Figures 3 to 4 The process of lifting is such that the compensating link formed by the elongated hole 42 and the pin 40 allows the front end of the movable bracket frame 25 to descend again to approximately the same degree during the fan-wing lifting process, which would otherwise be affected by the vertical force component F applied to the movable bracket frame 25 during the fan-wing lifting process. v And thus, the movable bracket frame 25 can rotate freely around the pin 36 guided in the tilt guide 35 during lifting and lowering, thereby counteracting the undesirable tilting posture of the movable bracket frame 25 during the lifting and lowering of the fan blade and thus counteracting the undesirable uneven load on the two rollers 26, 27.

[0032] In order to accommodate the elongated hole 42 in the connecting lever 31, in the illustrated embodiment, the connecting lever 31 is provided with a lug 44 at its first end 21. Thus, the lug 44 provides sufficient space to form the elongated hole 42, allowing the connecting lever 31 to be constructed as relatively elongated. List of reference numerals 11.
