Abstract
Description
[0001] The present invention relates to a damping device for audio equipment. The damping device comprises at least one support element for supporting at least one audio device. Furthermore, the damping device comprises at least one longitudinal support beam extending lengthwise and supporting the support element. The damping device also includes a base connected to the at least one longitudinal support beam. The at least one support element is movably connected to the base via the at least one longitudinal support beam for vibration decoupling.
[0002] Such a damping device is also known in practice as a device base, device foot, vibration absorber, vibration damper, vibration damper, vibration decoupling device, and / or resonance damper. It serves to decouple electrical devices, especially audio and / or hi-fi equipment, from their surroundings, such as a surface on which the device is placed. On the one hand, mechanical vibrations emanating from the electrical devices, particularly loudspeakers, are not to be transmitted into the surroundings, especially the surface. On the other hand, electrical devices themselves, especially playback devices such as CD players or record players, are not to pick up unwanted vibrations from their surroundings.
[0003] A disadvantage of known damping devices of the type mentioned above is that they can be comparatively complex in design, resulting in high manufacturing costs. Furthermore, satisfactory vibration decoupling is often not achieved, which can impair the playback quality of audio equipment, among other things.
[0004] The present invention is therefore based on the objective of providing a damping device with a structurally simple design and improved vibration decoupling.
[0005] The problem is solved by a damping device according to claim 1. Advantageous embodiments of the invention can be found in the dependent claims relating thereto and in the following description.
[0006] The damping device according to the invention has several longitudinal beam sections stretched by means of the base and angled to each other by a maximum of 90 degrees, in particular at least substantially parallel to each other, which are formed by the at least one longitudinal beam and on which the support element is supported.
[0007] In the case of multiple longitudinal beams, the longitudinal beam sections, which are angled to each other by a maximum of 90 degrees, and in particular run at least essentially parallel to each other, are formed by at least one, but not necessarily by all, of the multiple longitudinal beams.
[0008] The longitudinal beam sections are preferably clamped to the base in such a way that the longitudinal beam sections have at least one end connected to the base. Preferably, the connection between the longitudinal beam section and the base is achieved without deflection and / or angling of the longitudinal beam. This facilitates a structurally simple embodiment of the invention.
[0009] To securely support the support element, the longitudinal beam sections are preferably arranged side by side and, in particular, spaced apart from one another. Furthermore, the longitudinal beam sections advantageously span a plane that is arranged parallel to a receiving surface of the support element facing the audio device. In the case of a damping device standing on a base, this plane is preferably arranged, or should be arranged, parallel to the base.
[0010] The term "longitudinal beam sections angled at a maximum of 90 degrees to each other, and in particular running at least substantially parallel to each other" refers to an arrangement in which, particularly when viewed from a top view of the damping device, i.e., perpendicular to the receiving surface of the support element, the angle between the longitudinal beam sections is a maximum of 90 degrees, preferably a maximum of 45 degrees, particularly preferably a maximum of 15 degrees, further particularly preferably a maximum of 5 degrees, and in particular 0 degrees. Preferably, the longitudinal beam sections thus run parallel to each other.
[0011] The support element is preferably supported on the longitudinal beam sections in such a way that a connection between the support element and the longitudinal beam is made directly via the longitudinal beam sections and, in particular, not via any other part of the longitudinal beam, such as a region of the longitudinal beam(s) adjacent to the angled or parallel longitudinal beam sections. For ease of connection, the support element is preferably connected to the longitudinal beam sections at least via one upper surface and / or rests on this upper surface. Furthermore, the support on the longitudinal beam sections is preferably symmetrical with respect to the base and, in particular, centered. This allows any elasticity of the longitudinal beams to be used to their advantage. Symmetrical support is understood to mean support with equal distances to the base.A central support is understood to be a support between the ends of at least one of the longitudinal beam sections. Furthermore, the support of the beam element on the longitudinal beam sections means that the beam element is supported on at least several, and in particular on all, of the longitudinal beam sections.
[0012] To effectively accommodate audio equipment or other electrical devices of varying sizes, the support element preferably extends over a flat surface. Particularly preferably, the support element is plate-shaped. On the side facing the audio equipment, the support element is preferably flat.
[0013] The longitudinal beam(s) is / are preferably arranged, at least partially, below and / or embedded in the support element. This allows the longitudinal beam(s) to support the support element in a structurally simple manner. The base is preferably arranged, at least partially, below the support element.
[0014] The damping device according to the invention achieves improved vibration decoupling and improved sound fidelity in audio equipment. The invention is based, among other things, on the finding that supporting the support element on several longitudinal beam sections angled to one another or running parallel to each other is particularly advantageous. The parallel arrangement of the longitudinal beam sections enables a relative movement of the support element to the base with multiple degrees of freedom, which is particularly beneficial for vibration decoupling and damping. On the one hand, relative movement along a longitudinal direction of the longitudinal beam sections is enabled. On the other hand, relative movement transversely, i.e., obliquely or perpendicularly, to the longitudinal direction of the longitudinal beam sections, particularly in the vertical direction, is also enabled. This advantage is also achieved by arranging the longitudinal beam sections at an angle of no more than 90 degrees to one another.Furthermore, the angled arrangement of the longitudinal beam sections structurally prevents undesirably large movements of the support element in the longitudinal direction of the longitudinal beam sections. In particular, when, for example, a loudspeaker is positioned on the support element such that its main sound propagation direction or the main direction of movement of a loudspeaker voice coil is aligned, in increasingly preferred order, at an angle of less than 45 degrees, 30 degrees, 22.5 degrees, 15 degrees, 10 degrees, or 5 degrees, and especially at least approximately parallel, to the longitudinal direction of the longitudinal beam sections, a particularly high improvement in vibration decoupling or damping and sound fidelity can be achieved.
[0015] In a preferred embodiment of the invention, the support element is supported at several spaced-apart points on at least one of the longitudinal beam sections. Particularly preferably, the support element is supported at several spaced-apart points on several, in particular all, longitudinal beam sections that are angled or parallel to each other. This ensures secure support of the support element. Furthermore, a preferably existing floating bearing of the support element is facilitated in a structurally simple manner.
[0016] Vibration decoupling can be further improved by, in a further preferred embodiment of the invention, mounting the support element on the longitudinal beam sections in a floating manner, particularly in a longitudinal direction of the longitudinal beam sections. This achieves at least partial vibration decoupling in the longitudinal direction of the longitudinal beam sections by allowing relative movement between the support element and the longitudinal beam along this longitudinal direction.
[0017] Preferably, the damping device also includes at least one spacer, preferably made of wood, which is arranged between the at least one support element and the at least one longitudinal beam. The spacer allows for the preferably floating mounting of the support element on the longitudinal beam, particularly on the angled or parallel longitudinal beam sections, to be implemented in a structurally simple manner. For this purpose, at least one, and preferably at least two, spacers are advantageously arranged between the support element and several, and preferably each, of the longitudinal beam sections. In the case of a floating mounting, the spacer(s) are preferably floating on the longitudinal beam sections, particularly in their longitudinal direction. The spacer can be rigidly connected to the support element or at least formed by it.This ensures secure support of the support element and targeted force transmission into the longitudinal beam sections. It also allows for particularly effective vibration decoupling in the longitudinal direction of the longitudinal beam sections.
[0018] Advantageously, the spacer at least partially surrounds the at least one longitudinal beam and is, in particular, slidably supported on the longitudinal beam. The spacer preferably surrounds the angled or parallel section of the longitudinal beam when viewed in the longitudinal direction of the longitudinal beam section. For this purpose, the spacer, viewed in the longitudinal direction of the longitudinal beam sections, can preferably have an inverted U-shaped cross-section. This results in a particularly simple implementation of a floating support.
[0019] In particular, the longitudinal beam is designed in a continuous strand and preferably as a rope, especially a wire rope. A rope-like design is understood to mean a design such as a rope, yarn, thread, cord, chain, cable, tape, wire, or the like. Further improvement in vibration damping or decoupling can be achieved by alternatively or additionally sheathing the longitudinal beam, especially at least a section thereof, with a plastic material. In the case of a longitudinal beam designed as a rope, it is preferably a wire rope, especially a steel cable. The preferred wire rope is particularly durable, easily tensioned, and has a high load-bearing capacity. Thus, a structurally simple, stable, and, in particular, durable connection between the support element and the base can be achieved.
[0020] Vibration decoupling is further improved, particularly in the vertical direction, by connecting the support element elastically to the base via the longitudinal beam sections in a preferred embodiment of the invention. For this purpose, the longitudinal beam is designed to be flexible. However, it is not essential that the longitudinal beam itself exhibits high elasticity, as would be the case with an elastic rope, rubber band, or the like. The crucial factor is that the longitudinal beam allows relative movement of the support element to the base, particularly in the vertical direction, i.e., in a direction perpendicular to a surface when a damping device is arranged on the surface.Due to the elastically movable connection, when the support element and the base move relative to each other, particularly in the vertical direction, the longitudinal beam, preferably its sections, returns the support element to its initial position before the relative movement. The longitudinal beam can exert a restoring force on the support element to achieve this. The longitudinal beam can be designed and / or arranged to be elastically deformable, so that the longitudinal beam sections deform elastically when the support element moves relative to the base. Such elastic deformability would be present, for example, in a tensioned longitudinal beam designed as a wire rope. Alternatively, the longitudinal beam can be held by the base in a way that allows it to bend elastically.
[0021] In a further advantageous embodiment of the invention, the base is designed as a frame, and the longitudinal beam sections preferably extend symmetrically between two diverging ends of the frame, particularly with respect to a central plane of the frame. In particular, the base is open in the center when viewed from above. This creates space both for receiving the longitudinal beam and for allowing the longitudinal beam to deflect vertically. Preferably, the frame is formed from L-shaped frame profiles. The longitudinal beam sections can then be arranged between the frame profiles. Alternatively, the longitudinal beams and / or longitudinal beam sections can be arranged vertically above the respective frame profiles. Viewed from above, the frame profiles preferably define the edges of the frame. Viewed from above, the frame is also preferably rectangular, optionally with rounded corners.The support element can also be rectangular when viewed from above, optionally with rounded corners. This makes the damping device particularly well-suited to the common shapes of electrical appliances. The central plane is, in particular, a vertical plane when the damping device is in its operating position. With this type of base design, a symmetrical introduction of (residual) vibrations into the base is achieved, resulting in at least partial vibration cancellation. This further improves vibration damping and decoupling.
[0022] In a further preferred embodiment, the base is designed as a frame, and the longitudinal beams and / or longitudinal beam sections are assigned to the respective, in particular longitudinal, frame profiles of the frame and run parallel to them. The longitudinal beams or longitudinal beam sections assigned to the frame profiles are preferably arranged close to, in particular beside and / or above, their assigned frame profile. When arranged parallel to the frame profile, a longitudinal direction of the longitudinal beam section runs parallel to a longitudinal direction of the frame profile. Thus, the forces occurring during operation are advantageously introduced in the longitudinal direction. The frame profiles can run at a maximum angle of 90 degrees to each other, preferably at most 45 degrees, particularly preferably at most 15 degrees, and further, particularly preferably at most 5 degrees, and in particular at least approximately parallel to each other.
[0023] Preferably, the at least one longitudinal beam is rigidly connected to the base. A rigid connection between the longitudinal beam and the base is understood to mean a fixed connection, with respect to movement, of at least one part, in particular one end, of the longitudinal beam. For this purpose, the longitudinal beam can be clamped or screwed to the base, for example, at at least one of its ends. This facilitates a particularly simple design and simplifies the preferably tensioned mounting of the longitudinal beam by means of the base.
[0024] Advantageously, the longitudinal beam is held under tension by the base and preferably connected to the base in a way that allows for retensioning using tensioning devices. This results in a particularly simple implementation of an elastically movable, especially flexurally elastic, connection between the longitudinal beam and the base. Furthermore, the retensioning capability ensures improved vibration decoupling in the long term.
[0025] In particular, the damping device has several longitudinal beams, each forming at least one of the longitudinal beam sections that are angled to each other by a maximum of 90 degrees, and in particular, run at least substantially parallel. This is particularly simple from a structural point of view, as it eliminates the need for deflections of the longitudinal beam, associated deflection means of the damping devices, and / or connecting sections of the longitudinal beam to join the longitudinal beam sections. In a structurally particularly simple embodiment, at least one, and in particular all, longitudinal beams and / or longitudinal beam sections run straight. The longitudinal beams and / or longitudinal beam sections then run straight and / or without deflection, especially with respect to their unloaded state without any force exerted by the support element.
[0026] Preferably, the support element is at least partially made of a material with a density of 2 g / cm³. 3 up to 4 g / cm² 3 , preferably of 2.2 g / cm³ 3 up to 3.4 g / cm³ 3 , particularly preferred at 2.4 g / cm³ 3 up to 3.2 g / cm³ 3 , in particular 2.6 g / cm² 3 up to 3.0 g / cm³ 3 The support element is preferably at least partially, preferably at least predominantly, particularly preferably at least substantially, and especially at least almost exclusively, made of this material. Tests have shown that this results in particularly good vibration damping and decoupling.
[0027] Vibration damping or decoupling can be further improved by, in a preferred embodiment of the invention, making the support element at least partially from multi-layered rock and / or metamorphic rock, preferably slate. Such a composition of the support element has also proven to be particularly advantageous in tests.
[0028] In a further advantageous embodiment of the invention, the damping device comprises at least one base-supporting foot and / or at least one base-supporting support element for wall mounting the base. The foot and / or the support element serve to ensure the secure mounting and / or stability of the damping device. Furthermore, the foot(s) and / or support element(s) can themselves possess damping properties. For this purpose, the foot can, for example, be designed as a plastic and / or rubber damper, a tapered truncated cone (so-called "spike"), or the like. The support element, which is particularly angled, can accordingly be provided with a plastic and / or rubber layer for placement between the base and the remaining support element.
[0029] Preferably, the damping device comprises several support elements for carrying at least one audio device each, with each support element having several longitudinal beam sections of the at least one longitudinal beam that are angled to each other by at most 90 degrees, and in particular, that run at least substantially parallel to each other, on which the respective support element is supported. This allows the advantages described above to be utilized for multiple audio devices. Several support elements can share a common base, i.e., be spanned by means of a common base, or be connected by means of their own bases via the respective longitudinal beams. In the case of multiple bases, modular expandability of the damping device is thus easily achieved. In this case, several bases can share a common foot and / or a common support element.In the case of a common base, at least one stiffening element, such as a rod, additional frame profile or similar, can be provided for the connection of the longitudinal sides of the base, particularly for stiffening at the center.
[0030] The problem initially posed is also solved by an arrangement comprising at least one damping device as described above or below, and an audio device with a loudspeaker arranged on the support element, wherein this arrangement benefits from the advantages of the damping device described above or below. In particular, the vibration decoupling is especially effective if, in a top view, the direction of vibration of the loudspeaker voice coil runs, in an increasingly preferred sequence, at an angle of less than 45 degrees, 30 degrees, 22.5 degrees, 15 degrees, 10 degrees, or 5 degrees, and in particular at least approximately parallel, to the longitudinal extent of at least one, and in particular all, of the longitudinal support sections.

[0032] Individual technical features of the embodiments described below can also be combined with previously described embodiments and the features of one of the independent claims and any further claims to form articles according to the invention. Where appropriate, functionally equivalent elements are provided with identical reference numerals.
[0033] Fig. 1 to Fig. Figure 4 shows, in an overall view, a first embodiment of a damping device 2 for a schematically depicted audio device 3. The damping device 2 has a support element 4, shown here in plan view as rectangular and plate-shaped, on which the audio device 3 is supported or on which it is placed (see Figure 4). Fig. 1, Fig. 2) The support element 4 is supported by elongated, round in cross-section and comparatively thin longitudinal beams 6 (see figure). Fig. 3, Fig. 4) supported. In the present case, the support element 4 is movably connected to the base 8 via the two longitudinal beams 6 for vibration decoupling or vibration damping.
[0034] How in particular Fig. As shown in Figure 4, the damping device 2 has several longitudinal beam sections 10 spanned by means of the base 8 and running at least substantially parallel to one another. The support element 4 rests on the base 8 via the longitudinal beam sections 10, which in this case are formed by two longitudinal beams 6, but could in principle also be formed by a single longitudinal beam 6. The parallel arrangement of the longitudinal beam sections 10 allows a relative movement of the support element 4 and the base 8 with several degrees of freedom, which, particularly when an audio device 3, for example designed as a loudspeaker, is arranged such that its main sound propagation direction 36 (see Figure 4) is determined by the longitudinal beam sections 10. Fig. 2) running parallel to the longitudinal direction of the longitudinal beam sections, a particularly advantageous vibration decoupling and consequently high sound fidelity of the audio device 3 is achieved. A vibration direction S of a loudspeaker 40, or its loudspeaker voice coil of the audio device 3, runs parallel to the main sound propagation direction 36 and parallel to the longitudinal extent of the longitudinal beam sections 10 ( Fig. 1, Fig. 2 and Fig. 4).
[0035] In particular Fig. 3 and Fig. It can be seen from 4 that the support element 4 is supported on both longitudinal beam sections 10 at several spaced-apart points 12, 12', which ensures secure support of the support element 4 and also allows tilting movements of the support element 4 to be better absorbed by the longitudinal beams 6.
[0036] The longitudinal beams 6 are in this case designed as strands and rope-like, namely as wire ropes. The support element 4 is elastically movably connected to the base 8 via the mutually parallel longitudinal beam sections 10 of the longitudinal beams 6. During relative movement of the support element 4 in the vertical direction 26 (cf. Fig. 3) Elastic deformation of the longitudinal beams 6, in particular of the longitudinal beam sections 10, occurs, thereby restoring the support element 4 to its initial position before the relative movement. This promotes vibration decoupling in the vertical direction 26.
[0037] The base 8 is designed as a frame, in this case consisting of four profiles with L-shaped cross-section and a rectangular shape in plan view (see below). Fig. 4) The longitudinal beam sections 10 are arranged symmetrically between two diverging ends 16, 16' of the frame with respect to a central plane 18 of the frame. This allows, among other things, the compensation of any (residual) vibrations introduced into the frame.
[0038] In the present embodiment, the damping device 2 has several longitudinal beams 6, each forming one of the parallel longitudinal beam sections 10. This results in a particularly simple design of the damping device 2. Connections of the longitudinal beam sections 10 are also possible, but more complex, for example by a Z-, O- or C-shaped configuration of the longitudinal beam 6.
[0039] Fig. 5 and Fig. Figure 6 shows the rigid connection of the longitudinal beam 6 to the base 8, which is implemented here as a screw connection. The base 8 has, in plan view, approximately C-shaped connection points 28, in particular with parallel stop surfaces 30, whereby the longitudinal beam 6 is connected to the base 8 via the connection points 28. In this case, the longitudinal beam 6 has a threaded terminal 32, also called a screw terminal, at at least one of its ends for connection to the base 8. This threaded terminal 32 simultaneously constitutes a tensioning device 20, by means of which the longitudinal beam 6 can be tensioned or retensioned relative to the base 8. Alternatively or additionally, the longitudinal beam 6 can also include a conventional (wire rope) turnbuckle, shroud turnbuckle, or the like.The advantages resulting from the arrangement of the longitudinal beams 6 for vibration decoupling can thus be guaranteed in the long term, even after any change in length of the longitudinal beam 6.
[0040] This, among other things, in Fig. The support element 4 shown in Figure 7 is made of slate with a density of approximately 2.6 g / cm³. 3 up to 3.0 g / cm³ 3 manufactured. Particularly advantageous damping properties were found in this material during testing, which significantly exceed those of other stone slabs.
[0041] In particular Fig. It can be seen from Figure 8 that the support element 4 is floatingly mounted on the longitudinal beam sections 10, particularly in a longitudinal direction 34 of the longitudinal beam sections 10. For this purpose, the support element 4 rests loosely on the longitudinal beam sections 10. Optionally, at least one spacer 14, preferably made of wood, is arranged between the support element 4 and the longitudinal beams 6. In this case, the damping device 2 comprises several spacers 14 for each longitudinal beam section 10. The spacers 14 at least partially surround the longitudinal beam 6 and are supported on the respective longitudinal beam 6 so as to be displaceable at least in the longitudinal direction 34. This allows for a simple and precise force transmission into the longitudinal beams 6 and, if necessary, the required distance to them, thus implementing the floating mounting.
[0042] For ease of setup, the damping device 2 has at least one foot 22 supporting the base 8. Alternatively or additionally, at least one support element (not shown), preferably designed as a support bracket, can be provided for wall mounting the base 8.
[0043] Fig. 9 to Fig. Figure 12 shows an overall view of a second embodiment of a damping device 2 according to the invention for a schematically depicted audio device 3. This damping device 2 has a support element 4, which is rectangular in plan view (here trapezoidal) and plate-shaped, on which the audio device 3 is supported or placed (see Figure 12). Fig. 9, Fig. 10) The corners of the support element 4 can be rounded, as shown here, or without rounding. The support element 4 and / or the base 8 can be adapted to the shape of the audio device 3, which in this case could be trapezoidal, particularly in plan view. The support element 4 is supported by elongated, round in cross-section, and comparatively thin longitudinal beams 6 (see Figure 10). Fig. 11, Fig. 12) supported. In the present case, the support element 4 is movably connected to the base 8, which is connected to the longitudinal beams 6, via the two longitudinal beams 6, for vibration decoupling or vibration damping.
[0044] How in particular Fig. As shown in Figure 12, the damping device 2 has several longitudinal beam sections 10 spanned by means of the base 8 and angled relative to each other. The support element 4 rests on the base 8 via the longitudinal beam sections 10, which in this case are formed by two separate longitudinal beams 6, but could in principle also be formed by a single longitudinal beam 6. The arrangement of the longitudinal beam sections 10 allows for a relative movement of the support element 4 and the base 8 with several degrees of freedom, which, particularly when an audio device 3, for example designed as a loudspeaker, is arranged such that its main sound propagation direction 36 (see Figure 12) is determined by the longitudinal beam sections 10. Fig. 10) at least approximately parallel, here angled by about 10 degrees, to the longitudinal direction of the longitudinal beam sections 10 and especially between them, a particularly advantageous vibration decoupling and thus high sound fidelity of the audio device 3 is achieved. For this purpose, the longitudinal beam sections 10 are angled to each other by about 20 degrees. A vibration direction S of a loudspeaker 40, or rather its loudspeaker voice coil of the audio device 3, runs parallel to the main sound propagation direction 36 and at an angle of about 10 degrees to the longitudinal extent of the longitudinal beam sections 10 (cf. Fig. 9, Fig. 10 and Fig. 12).
[0045] In particular Fig. 11 and Fig. It can be seen from 12 that the support element 4 is supported on both longitudinal beam sections 10 at several spaced-apart points 12, 12', which ensures secure support of the support element 4 and also allows tilting movements of the support element 4 to be better absorbed by the longitudinal beams 6.
[0046] The longitudinal beams 6 are in this case designed as strands and rope-like, namely as wire ropes. The support element 4 is elastically movably connected to the base 8 via the longitudinal beam sections 10 of the longitudinal beams 6, which are angled relative to each other. During relative movement of the support element 4 in the vertical direction 26 (see figure 1), the support element 4 moves in a direction of vertical movement. Fig. 11) Elastic deformation of the longitudinal beams 6, in particular of the longitudinal beam sections 10, occurs, thereby restoring the beam element 4 to its initial position before the relative movement. This promotes vibration decoupling in the vertical direction 26.
[0047] The base 8 is designed as a frame, in this case consisting of four profiles with L-shaped cross-section and a rectangular shape in plan view (see below). Fig. 12) In the case of rounded corners, as in the present case, the term "corners" refers to those imaginary corners that would exist without rounding. The longitudinal beam sections 10 are arranged symmetrically between two diverging ends 16, 16' of the frame with respect to a central plane 18 of the frame. This allows, among other things, any (residual) vibrations introduced into the frame to be particularly well compensated. In addition, the longitudinal beam sections 10 are covered here in the vertical direction 26, in particular at least on the lower or bottom side, by the base 8, which makes their arrangement particularly secure. Furthermore, the longitudinal beam sections 10, which are straight in this case, run parallel to frame profiles of the base 8, which is designed as a frame.
[0048] In the present embodiment, the damping device 2 has several longitudinal beams 6, each forming one of the longitudinal beam sections 10 that are angled relative to each other. This results in a particularly simple design of the damping device 2. Connections of the longitudinal beam sections 10 are also possible, but more complex, for example by means of a Z-, O- or C-shaped configuration of the longitudinal beam 6.
[0049] The support element 4 is floatingly mounted on the longitudinal beam sections 10, particularly in a respective longitudinal direction 34 of the longitudinal beam sections 10. Simultaneously, the angled arrangement of the longitudinal beam sections 10 relative to each other limits the movement of the support element 4 and prevents excessive movement of the support element 4, for example, up to the base 8, which is spaced at a distance in the longitudinal direction 34 from it. For this purpose, the support element 4 rests loosely on the longitudinal beam sections 10. Optionally, at least one spacer 14, preferably made of wood, is arranged between the support element 4 and the longitudinal beams 6. In this case, the damping device 2 comprises several spacers 14 for each longitudinal beam section 10. The spacers 14 at least partially surround the longitudinal beam 6 and are supported on the respective longitudinal beam 6 so as to be displaceable at least in the longitudinal direction 34.This allows for a more precise force transmission into the longitudinal beams 6 and any necessary distance to them, and enables the implementation of the floating bearing.
[0050] Fig. 13 and Fig. Figure 14 shows the rigid connection of the longitudinal beam 6 to the base 8, which is implemented here as a screw connection. The base 8 has, in plan view, approximately C-shaped connection points 28, in particular with parallel stop surfaces 30, whereby the longitudinal beam 6 is connected to the base 8 via the connection points 28. In this case, the longitudinal beam 6 has a threaded terminal 32, also called a screw terminal, at at least one of its ends for connection to the base 8. This threaded terminal 32 simultaneously constitutes a tensioning device 20, by means of which the longitudinal beam 6 can be tensioned or retensioned relative to the base 8. Alternatively or additionally, the longitudinal beam 6 can also include a conventional (wire rope) turnbuckle, shroud turnbuckle, or the like.The advantages resulting from the arrangement of the longitudinal beams 6 for vibration decoupling can thus be guaranteed in the long term, even after any change in length of the longitudinal beam 6.
[0051] This, among other things, in Fig. The support element 4 shown in Figure 15 is made of slate with a density of approximately 2.6 g / cm³. 3 up to 3.0 g / cm³ 3 manufactured. Particularly advantageous damping properties were found in this material during testing, which significantly exceed those of other stone slabs.
[0052] In particular Fig. It can be seen from figure 16 that the damping device 2 in this case has at least one foot 22 supporting the base 8 for easy setup. Alternatively or additionally, at least one support element (not shown), preferably designed as a support bracket, can be provided for wall mounting the base 8.
