Description

[0001] The invention relates to a sound insulation device for elevators comprising a sound insulation element, a mounting plate that can be operatively connected to an elongated elevator attachment, at least two insulation plates, wherein a first insulation plate is arranged with a flat side on a first side of the mounting plate and a second insulation plate is arranged with a flat side on an opposite second side of the mounting plate, and wherein the first and second insulation plates consist of an elastically deformable insulation material, a first cover plate that rests against the first insulation plate on a side facing away from the mounting plate and that can be connected to a shaft wall by means of fastening means, a second cover plate that rests against the second insulation plate on a side facing away from the mounting plate, and a clamping means by means of which the first cover plate and the second cover plate can be clamped against each other.wherein the first insulation board and the second insulation board are compressed perpendicular to their flat sides.

[0002] Furthermore, the invention relates to an elevator arrangement.

[0003] From DE 10 2019 000 124 A1, a sound insulation device for elevators is known, by which an elevator is acoustically decoupled from a shaft wall. For this purpose, a sound insulation element is attached on one side to an elevator component, for example, a vertical guide rail, and on the other side to the shaft wall. The sound insulation element is attached to the elevator component by means of a retaining plate located between two insulation plates. The two insulation plates are pressed together by a clamping device that engages cover plates adjoining the outer sides of the insulation plates, in order to improve the desired sound insulation and prevent structure-borne noise transmission from the elevator to the shaft wall. The sound insulation element is secured to the shaft wall via the cover plate facing the shaft wall by means of conventional fasteners, such as anchors and screws.A disadvantage of the known sound insulation device is that, particularly in freight elevators such as car lifts, where the elevator cars are subjected to high forces, structure-borne noise transmission at low frequencies is not sufficiently minimized. A similar arrangement is known from DE202018103587U1, where a retaining plate is also arranged between two elastic damping layers.

[0004] The object of the present invention is therefore to further reduce structure-borne sound transmission from an elevator to a fixed shaft.

[0005] To solve this problem, the invention in conjunction with the preamble of claim 1 is characterized in that at least two sound insulation elements are provided, wherein the flat sides of the first insulation panel and the second insulation panel of a first sound insulation element are arranged at a predetermined angle to the flat sides of a first insulation panel and a second insulation panel of a second sound insulation element.

[0006] The particular advantage of the invention lies in the fact that by arranging at least two sound insulation elements oriented in different directions, which are preferably identical in design, structure-borne noise transmission in different directions can be reduced. For example, if two sound insulation elements are arranged at right angles to each other, structure-borne noise transmission can be reduced both in the direction of shaft depth and in the direction of shaft width. In particular, the sound insulation element acting in the direction of sound depth can minimize structure-borne noise transmission when a car enters and exits the elevator car. The basic idea of ​​the invention is to provide sound attenuation not only in one, but in at least two directions.

[0007] According to a preferred embodiment of the invention, two preferably identical sound insulation elements are arranged at right angles to each other, so that the directions of action of the sound attenuation also run at right angles to each other. The directions of action of the sound attenuation or sound insulation are adapted to the directions of force exerted on the elevator or on the loads and / or persons to be transported by the elevator. While a first sound insulation element has a direction of action that coincides with the width of the shaft, a second sound insulation element has a direction of action that coincides with the depth of the shaft. The second sound insulation element is particularly effective in minimizing structure-borne noise transmission resulting from dynamic force exerted on the elevator.

[0008] According to a further development of the invention, a retaining plate of the first sound insulation element is integrally connected to a retaining plate of the second sound insulation element. Advantageously, the at least two sound insulation elements are arranged close to each other, thus reducing the number of components required. Alternatively, the first and second sound insulation elements can be arranged separately and independently of each other, with each sound insulation element being connected to the elevator attachment and the shaft wall via separate fastening means.

[0009] In a further development of the invention, the mounting plate of the first sound insulation element and the mounting plate of the second sound insulation element are components of a U-shaped mounting profile. Insulation panels of the first sound insulation element extend along a flat apex section of the U-shaped mounting profile, while insulation panels of the second sound insulation element extend along a first leg section of the mounting profile. A second leg section of the U-shaped mounting profile is connected to the elevator attachment via fasteners. Advantageously, the U-shaped mounting profile can serve as a base component for providing an integrated sound insulation device with two sound insulation elements arranged perpendicular to each other. The sound insulation device thus has a compact and cost-effective design.

[0010] According to a further development of the invention, the second sound insulation element comprises an angle profile, wherein a first leg of the angle profile serves as the first cover plate of the second sound insulation element, and wherein a second leg serves for direct contact with the shaft wall and is fixed to the shaft wall by means of fasteners. The second leg is preferably arranged as an extension of the apex section of the U-shaped retaining profile, so that both the U-shaped retaining profile and the angle profile can be fastened to the same flat shaft wall. The second sound insulation element thus extends in an area between two fastening points on the shaft wall.

[0011] According to a further development of the invention, the insulating material comprises an elastomer with a compression hardness in the range of 0.03 N / mm² to 1.2 N / mm². The insulating material is thus relatively flexible, which increases its insulating effect. To ensure that the insulating material can be compressed uniformly across its entire length, it is fully covered on both flat sides, namely by the cover plates on one side and the retaining plate on the other. Preferably, there is no free overhang of the insulating material relative to the adjacent metallic plates.

[0012] According to a further development of the invention, a spacer element is arranged in the area of ​​the clamping device to limit the compressibility of the insulation panel. This spacer element has a length such that clamping the first and second cover plates of the respective sound insulation element compresses the insulation panel by at least 8% of its thickness. Investigations have shown that structure-borne noise transmission can only be effectively reduced with a thickness reduction of 8% or more, relative to the total thickness. Preferably, the thickness reduction of the insulation panel in the installed state is in the range of 8% to 12% of the total thickness of the insulation panel, and particularly 10% of the total thickness.

[0013] According to a further development of the invention, an emergency stop is formed on the mounting plate of the first sound insulation element and / or the second sound insulation element, creating an air gap between the emergency stop of the mounting plate and a first cover plate of the respective sound insulation element. This advantageously counteracts undesirable bending of the mounting plate due to high stress. The air gap can be in a range of 3 mm to 7 mm.

[0014] According to a further development of the invention, the second leg section of the U-shaped retaining profile has a step contour, so that a prescribed pitch dimension can be set during the assembly of the elevator attachment designed as guide rails.

[0015] To solve the problem, the elevator arrangement has the features of claim 12.

[0016] The particular advantage of the elevator arrangement according to the invention is that sound insulation is generated in different directions. Only one of the sound insulation elements is directly connected to the shaft wall via a cover plate, while the other sound insulation element merely rests against the same shaft wall with its leg (mounting leg) running at an angle to the cover plate.

[0017] According to a further development of the invention, the first sound insulation element extends in the direction of sound depth and the second sound insulation element in the direction of sound width, wherein the distance of the first and second sound insulation elements to an intersection point of an extension plane of the same is less than the width of the respective sound insulation elements. The two sound insulation elements are thus arranged relatively close to each other spatially, or both sound insulation elements are arranged relatively close to the elevator attachment, so that undesirable leverage forces acting on the sound insulation elements can be minimized.

[0018] According to a further development of the invention, the sound insulation elements are arranged on both sides of an elevator attachment. In this way, a secure sound-insulating fastening of the elevator attachment to the shaft wall is ensured.

[0019] According to a further development of the invention, the vertical extent of the sound insulation elements is greater than the horizontal extent, so that the distance between the sound insulation elements and the elevator component can be kept relatively small. This avoids undesirable leverage forces.

[0020] Further advantages of the invention will become apparent from the further dependent claims.

[0021] An embodiment of the invention is explained in more detail below with reference to the drawings.

[0022] They show: Figure 1 is a perspective view of an elevator arrangement with an elevator car and elevator attachments arranged vertically on opposite sides, which are attached to a shaft wall via a sound insulation device; Figure 2 is a top view of a sound insulation device arranged to the right of the elevator attachment; Figure 3 is an enlarged section of a detail A of the sound insulation device according to Figure 2 Figure 4 shows an enlarged sectional view of a detail B of the sound insulation device in Figure 2 Figure 5 shows a side view of the sound insulation device according to Figure 2 in shaft width direction X, Figure 6 a side view of the sound insulation device according to Figure 2 in shaft depth direction Y and Figure 7 an exploded view of the sound insulation device.

[0023] An elevator arrangement is in Figure 1The elevator car 1 consists essentially of an elevator car, two vertically extending elevator attachments 3 arranged on opposite shaft walls 2 of a shaft, and a sound-insulating mounting device comprising a plurality of sound insulation devices 4 by means of which the elevator attachment 3 is fastened to the shaft wall 2. The sound insulation devices 4 are arranged on both sides of the elevator attachment 3 and / or behind the elevator attachment 3. In the present embodiment, the sound insulation devices 4 are arranged in pairs on the same horizontal plane on both sides of the elevator attachment 3.

[0024] The elevator component 3 can be designed as a lifting column with an integrated guide rail or as a guide rail itself, allowing the elevator car 1 to move vertically up and down. The shaft wall 2 can be part of a building within which a vehicle 5, inside the elevator car 1, can be moved to different levels, for example, to different parking levels. For this purpose, a mechanical support element in the form of a chain, rope, belt, or hydraulic system, such as a hydraulic cylinder and hydraulic piston, is integrated into the lifting column 3, enabling the elevator car 1 to be moved up and down by means of a drive unit, such as a motor.

[0025] The sound insulation device 4 comprises, on the one hand, fastening means for attaching the elevator attachment 3 to the shaft wall 2 and, on the other hand, sound insulation means for preventing structure-borne sound transmission from the elevator car 1 to the shaft wall 2.

[0026] In the present embodiment, the sound insulation device 4 has two sound insulation elements: a first sound insulation element 6, which acts in a sound width direction X, and a second sound insulation element 7, which acts in a sound depth direction Y.

[0027] In the present embodiment, the first sound insulation element 6 is integrally connected to the second sound insulation element 7.

[0028] The first sound insulation element 6 has a retaining plate 8, insulation plates 9 and 10 adjoining each of the opposite flat sides of the retaining plate 8, and cover plates 11 and 12 adjoining each of the insulation plates 9 and 10. A first insulation plate 9 is arranged on one side of the retaining plate 8 facing the shaft wall 2. A first cover plate 11 adjoins the first insulation plate 9 on one side facing away from the retaining plate 8. A second insulation plate 10 is arranged on one side of the retaining plate 8 opposite the first insulation plate 8. A second cover plate 12 adjoins the second insulation plate 10 on one side facing away from the retaining plate 8.

[0029] The retaining plate 8, as well as the first cover plate 11 and the second cover plate 12, are made of a metal material. The first insulation plate 9 and the second insulation plate 10 are made of an insulating material. In the present embodiment, the insulating material consists of an elastomer or an elastomer-based material, wherein the volume fraction of the elastomer content is at least 50% of the total volume of the material, with a compression hardness in the range of 0.03 N / mm² to 1.2 N / mm², preferably 0.05 N / mm² to 0.07 N / mm².

[0030] The second sound insulation element 7 comprises a mounting plate 13, two insulation panels 14 and 15, and two cover panels 16 and 17. The second sound insulation element 7 has the same layered structure as the first sound insulation element 6. A first insulation panel 14 is arranged on one side (flat side) of the mounting plate 13, and a second insulation panel 15 is arranged on the opposite side of the mounting plate 13. A first cover panel 16 adjoins the first insulation panel 14 on one side facing away from the mounting plate 13. A second cover panel 17 adjoins the second insulation panel 15 on one side facing away from the mounting plate 13. The insulation panels 9, 10, 14, and 15 are completely covered by their respective cover panels 11, 12, 16, and 17. Only the narrow sides of the insulation panels 9, 10, 14, and 15 may be exposed.

[0031] The sound insulation device 4 comprises clamping means 18 by means of which the first cover plate 11, 16 and the second cover plate 12, 17 of the first sound insulation element 6 and the second sound insulation element 7, respectively, are pressed together or clamped into a mounting position. The clamping direction or compression direction is perpendicular to a plane of extension E1 of the first sound insulation element 6 and a plane of extension E2 of the second sound insulation element 7, respectively.

[0032] For example, a bolt 18', 18" and a nut 18‴ can be provided as a clamping device 18, by means of which the first cover plate 11, 16 is clamped to the second cover plate 12, 17. This reduces the thickness of the first insulation plate 9, the second insulation plate 10, the first insulation plate 14, and the second insulation plate 15 by at least 8%. Preferably, the insulation plates 9, 10, 14, 15 are compressed such that they are compressed from their initial state by 10% to a thickness d in the assembled state. The degree of compression is preset and can be in a range between 8% and 12% of the thickness, preferably 10% of the initial thickness of the insulation plates 9, 10, 14, 15.

[0033] To determine the compressed thickness d of the insulation panels 9, 10, 14, 15, a spacer element 19 is provided, which, as a spacer sleeve of a predetermined length, surrounds the fastening bolt 18', 18" . The retaining plate 8, 13 of the first sound insulation element 6 and the second sound insulation element 7 has a larger bore for the passage of the fastening bolt 18', 18" than the insulation panels 9, 10, 14, 15 or the cover plates 11, 12 or 16, 17, respectively, so that an insulating ring 20 made of the insulating material can be inserted and prevents contact between the retaining plate 8, 13 and the spacer element 19, which is preferably also made of a metal material.

[0034] In the present embodiment, the retaining plate 8 of the first sound insulation element 6 and the retaining plate 13 of the second sound insulation element 7 are integrally connected. They form part of a U-shaped retaining profile 21, which has a flat apex section formed by the retaining plate 8 of the first sound insulation element 6, a flat first leg section formed by the retaining plate 13 of the second sound insulation element 7, and a second leg section 22 as a flat fastening section for attaching the retaining profile 21 to the elevator attachment 3. It is therefore an angled or right-angled U-shaped retaining profile 21.

[0035] The second leg section 22 is firmly connected to a side wall of the elevator attachment 3 via fastening means 23, which is designed as a bolt and nut.

[0036] The apex section 8 of the U-shaped retaining profile 21 is firmly connected to the shaft wall 2 by means of fasteners 24 (in the present embodiment, a screw / anchor element). Since the first sound insulation element 6, with its first cover plate 11, lies flat against the shaft wall 2 in the installed position, the screw 18' is designed as a countersunk screw, while the bolt 18" of the second sound insulation element 7 has a head projecting from the first cover plate 17, see figure. Figures 3 and 4 .

[0037] The apex section 8 of the U-shaped retaining profile 21 forms an angle φ of 90° with both the first leg section 13 and the second leg section 22, such that the two leg sections 13 and 22 are essentially parallel. The second sound insulation element 7 is thereby arranged perpendicular to the first sound insulation element 6, with the flat sides of the first and second insulation panels 9 and 10 of the first sound insulation element 6 running perpendicular to the sound width direction X, and the flat sides of the insulation panels 14 and 15 of the second sound insulation element 7 running perpendicular to the sound depth direction Y.

[0038] As from Figure 2As can be seen, the first cover plate 16 of the second sound insulation element 7 forms a first leg of an angle profile 25, which has a second leg 26 (fastening leg) for fastening the second sound insulation element 7 to the shaft wall 2. The first leg 16 and the second leg 26 of the angle profile 25 are arranged bent at a right angle φ, so that the first cover plate 16 of the second sound insulation element 7 can be fixed to the same shaft wall 2 via the fastening leg 26. The first cover plate 11 of the first sound insulation element 6 and the second leg 26 of the angle profile 25 run in a common plane under direct contact with the shaft wall 2. The second leg 26 is - like the first cover plate 11 of the first sound insulation element 6 - firmly connected to the shaft wall 2 via the fastening means 24.

[0039] In the installation position, the sound insulation device 4 is firmly connected to the elevator attachment 3 via the first leg section 13 of the retaining profile 21 and to the shaft wall 2 via the first cover plate 11 and the second leg 26 of the angle profile 25.

[0040] In the present embodiment, the insulation panels 9, 10, 14, 15 have a thickness d of 12.5 mm in the assembled state. The insulation ring 20 has a thickness of 8 mm, which corresponds approximately to the wall thickness of the retaining plate 8.

[0041] The thickness d of the respective insulation panels 9, 10, 14, 15 can, in their installed state, be in a range between 5 mm and 15 mm, preferably 11 mm to 13 mm.

[0042] The insulating material is made of an elastomer material, preferably a mixed-cell PUR elastomer (polyurethane), which preferably has a compression hardness at 10% compression in the range of 0.03 N / mm² to 1.2 N / mm², preferably 0.05 N / mm² to 0.07 N / mm².

[0043] The U-shaped retaining profile 21 has a first emergency stop 27 on the second leg section 22 and a second emergency stop 28 on the apex section 8, which are spaced apart in the assembled state via an air gap 29 from the first cover plate 11 of the first sound insulation element 6 and the first cover plate 16 of the second sound insulation element 7, respectively. The air gap 29 preferably has a length of 3 mm to 7 mm. In the event of overloading of the sound insulation device 4 during operation, a bending force, for example in the case of extreme overloading, can thus be limited both in the sound width direction X and in the sound depth direction Y.

[0044] Furthermore, the second leg section 22 of the U-shaped retaining profile 21 includes a step contour 30 with a plurality of steps on one narrow side, so that a prescribed pitch of the guide rail integrated in the elevator attachment 3 can be set using, for example, a pry bar. This simplifies the installation of the guide rail.

[0045] As from Figure 6 As can be seen, the second leg section 22 has horizontally extending elongated holes 31 in the assembly position. In this way, the U-shaped retaining profile 21 can be adjusted during assembly so that the first cover plate 11 of the first sound insulation element 6 comes into contact with the shaft wall 2 over its entire surface.

[0046] Preferably, the first sound insulation element 6 and, optionally, the second sound insulation element 7 are pre-assembled on the retaining profile 21. During the installation of the sound insulation device 4, only the fastening of the retaining profile 21 and the angle profile 25 to the elevator attachment 3 via the fasteners 23 and to the shaft wall 2 via the fasteners 24, respectively, is required on site.

[0047] As from Figure 2 As can be seen, only the first sound insulation element 6 is arranged under direct contact of the first cover plate 11 of the same on the shaft wall 2, while the second sound insulation element 7 is arranged perpendicular to the shaft wall 2 and spaced apart from the shaft wall 2.

[0048] A distance a of the first sound insulation element 6 and a distance b of the second sound insulation element 7 to an intersection point K, through which the extension plane E1 of the first sound insulation element 6 and the extension plane E2 of the second sound insulation element 7 pass, is smaller than a width b1 of the first sound insulation element 6 and a width b2 of the second sound insulation element 7. The distances a and b are chosen to be as small as possible so that the sound insulation device 4 has a compact design.

[0049] It should be noted that the first insulation panel 9 and the second insulation panel 10 of the first sound insulation element 6, as well as the first insulation panel 14 and the second insulation panel 15 of the second sound insulation element 7, are all identical in design. The insulation panels 9, 10, 14, and 15 each have rectangular flat sides, with a vertical longitudinal edge 32 being longer than a horizontal transverse edge 33 in the installed position. The insulation panels 9, 10, 14, and 15 are thus oriented vertically, which further enhances the compactness of the sound insulation device 4.

[0050] According to an alternative embodiment of the invention, not shown, several sound insulation elements can also be provided which are not arranged at a right angle to each other, but at an acute angle to each other, wherein adjacent sound insulation elements are arranged at an acute angle to each other.
