Abstract

The invention relates to a sanitary facility with a sanitary body and at least one support arrangement which has at least one damping element (2a, 2b, 2c). According to the invention, the damping element (2a, 2b, 2c) at least partially has a damping body (10a, 10b, 10c) formed from metal wire.

Description

Base body adjoining damping element.

The sanitary body is preferably a bathtub, a shower tray or a shower surface, but also a wash basin or the like as

Sanitary bodies come into consideration.

With regard to the preferred configurations as a bathtub, shower tray or shower surface, there is the requirement that high weight forces must be supported downwards during use. In the case of a shower tray and a shower surface, the weight of at least one user must be taken into account, which can act at different points and then lead to a locally different application of force. In the case of a bathtub, the weight of the water as it feels must also be taken into account. Finally, both bathtubs and shower trays and shower surfaces can be one

have not negligible dead weight.

In order to support such sanitary bodies, support arrangements are used

known in the form of tub feet or tub anchors. Tub feet

are often combined with a frame or a comparable support arrangement and are then used for selective

Force dissipation to a floor.

The base body can be one-part or, preferably, multi-part

be. In particular, within the scope of the invention, all

takes place at the side of a building structure.

Typical support arrangements in the form of tub feet are of a construction similar to one another from the prior art

known.

DE 10 2005 058 106 B4 describes generic support arrangements in the form of tub feet. The tub feet each have a multi-part base body and a damping element on the underside. The damping element is provided for sound decoupling and consists of foam or plastic. The base body comprises an upper housing made of plastic with a male threaded part. The screw shaft of a carriage bolt is received in the male threaded part, so that a height adjustment is possible with the carriage bolt. At the desired height, the carriage bolt can be fixed to the male threaded part and thus to the upper housing with a lock nut. The head of the carriage bolt is lens-shaped on the underside, with a lower part of the base body being latched to the head in the form of a clip. The lower part forms a receiving space for the carriage screw opposite

the cylindrical damping element.

DE 10 2005 058 106 B4 discloses a customary and widespread configuration of a tub base, the basic body described also within the scope of the present

Invention can be provided. Similar tub feet are also

Various building regulations, standards and other requirements must be taken into account for the assembly and use of sanitary facilities. This also includes provisions that deal with noise protection in building construction and in particular a reduction

employ corresponding noise emissions.

For example, the guideline VDI 4100 "Sound insulation in buildings - Apartments - Assessment of proposals for increased sound insulation", DIN 4109-1: 2018-01 "Sound insulation in building construction - Part 1: Minimum requirements" and

the SIA 181 "Sound insulation in building construction" must be taken into account.

For the Swiss standard SIA 181, for example, an investigation is carried out with a special pendulum drop hammer, which was developed by Empa as an interdisciplinary research institute and is therefore also known as the Empa pendulum drop hammer

becomes.

A more detailed description can be found, for example, in the publication "Eggenschwiler, K., Sperdin, V., and Schönwald, S. (2018)," New investigations into the measurement method for simulating building technology usage noises with the pendulum drop hammer ", Autumn Conference Swiss Society

for acoustics SGA-SSA, 8./9. November 2018 in Sursee.

To achieve good sound insulation, damping elements made of elastic plastic are often used in practice. With regard to the best possible sound insulation, a rather soft, flexible material is advantageous,

on the other hand, however, too strong deformations are certain

stands.

In order to influence and improve sound insulation, various approaches are known from the prior art. According to DE 199 11 343 C2, a tub support made of foam material is proposed, metal plates being provided for the distribution of force and for storage, on each of which a tub base is screwed. The tub feet have comparatively large structure-borne sound insulation elements made of an elastomer on their underside, which

for example can be attached by glue.

According to DE 94 06 980 U1, caps of foot elements have shaped portions on the underside which provide point-wise support

effect.

According to DE 10 2009 035 059 B4, barrier masses are proposed for improved sound decoupling, which should have a comparatively large mass of 5 to 20 kg. The barrier masses are between conventional tub feet and

arranged on the subsurface, the bulkheads being discrete

Overall arrangement comparatively complex and expensive.

Proceeding from the prior art, the present invention is based on the object of specifying a sanitary facility which is simply constructed and also has good sound-absorbing properties in the long term. Furthermore, a corresponding support arrangement in the form of a tub base should be provided

or trough anchors.

The subject of the invention and the solution to the problem are a sanitary facility according to claim 1 and a support arrangement in the form of a tub base or tub anchor

according to claim 12.

Proceeding from a sanitary facility according to the preamble of claim 1, it is thus provided according to the invention that the damping element is formed from metal wire

Has damping body.

For this purpose, the metal wire can be provided in an open structure and then compressed. According to a preferred embodiment of the invention, it is provided that the damping body has a knitted fabric formed with metal wire and subsequently compressed. A knitted fabric or a knitted fabric come into consideration in particular, the wires being closely intertwined with one another due to the formation of the loops. In the compressed

State is then provided a compact body from which

to be able to solve.

The formation of meshes is also particularly advantageous with regard to the desired elastic properties for the purpose of decoupling. On the one hand, according to the original mesh structure, many bends and bends remain, which cause elastic restoring forces, even in the compressed state. In addition, the stitch formation provides an open structure which, depending on the degree of compression, also has gaps and free spaces. After the compression with a suitable force and a plastic and elastic deformation, an elastic recovery takes place, which is due to the springback of the individual arches, bends and bends as well as the open macrostructure. These restoring forces that occur also depend largely on the elastic properties of the wire. In the preferred embodiment as a knitted fabric, the individual stitches can typically have a height between 1 mm and 15 mm, in particular between 3 mm and 15 mm, before compression

exhibit.

In the context of the invention, other structures formed from metal wire can also be considered, which after compression have the desired elastic damping and decoupling properties. For example, wires can also be provided as a woven fabric, random fleece or twisted in a spiral shape and then compressed in the desired manner

will.

When forming the damping element from compressed

Metal wire is the one provided for the initial compression

Damping body takes place.

The use of metal wire to form the damping body also results in a particularly long service life, while plastics are subject to a greater risk of material fatigue over a long period of time. This applies in particular if the metal wire is made of a suitable stainless steel, for example stainless steel of the type AISI 316L (1.4404). Damping elements made of plastic and in particular elastomer usually have a lower chemical resistance, with embrittlement over a longer period of time also due to aging processes

can occur.

In addition, a very good sound decoupling is surprisingly observed in the damping element, which is at least partially formed from compressed metal wire. It is assumed that this is due to a strongly non-linear behavior of the damping element in a force-displacement diagram. In the case of low forces, the damping element is initially very soft and flexible. However, a very steep rise is then observed in a displacement-force diagram, so that even with very large forces acting in comparison to damping elements

Plastic the degree of deformation can be limited.

elastic behavior.

It should also be noted that the usual loads in a sanitary facility are well below the permissible maximum load. If, for example, a shower tray or shower surface is supported by several tub feet, then in the extreme case practically all of the force can act on one foot with a corresponding load, namely when a point load occurs precisely there, for example from the foot of a user. With normal use and an even distribution of forces, the forces to be taken into account are much smaller. In the context of the invention, precisely with such a uniform load, the non-linear characteristic curve of the damping element results in a particularly advantageous soft one

Damping behavior.

As already explained above, the damping element is partially and preferably completely formed from metal wire and preferably from compressed metal wire, with a knitted fabric or another spatial arrangement of the metal wires being provided prior to compression. Against this background, a preferred embodiment of the invention provides that the damping body has a density between 2 g / cm * and 5.5 g / cm? having. Compared to a compact body made entirely of metal with the same external dimensions

results from a typical density of stainless steel of about 8

g / cm * a volume fraction between 25% and 70% metal, with between 75% and 30% of the volume remaining as free space. As explained further below, the damping element can only be formed from metal wire or can also comprise other materials. Even if further materials are contained, the density is preferably in the specified range, the metal wire preferably also being the main component with regard to the mass ratios

forms.

Damping elements with a damping body made of compressed metal wire are known from special applications, for example when particularly high temperature resistance is required. For this purpose, the

US 3,390,709, US 3,250,502, US 5,149,068, US 4,514,458 and DE 692 00 200 T2 are referred to. The use of corresponding damping bodies on the basis of compressed metal wire has not yet been considered in the field of sanitary installations despite the large number of different approaches

Considered.

In the context of the invention, the damping body typically has a thickness between 2 mm and 20 mm, preferably between 5 mm and 15 mm. The thickness is expediently determined in the support direction and in the uncompressed state. The effective damping path or the maximum provided compression is usually in

Range of about 0.3 mm or at most a few millimeters.

When the support arrangement is configured as a tub base, a base body can be provided within the scope of the invention - as already explained above - as is also described in DE 10 2005

058 106 B4 is known. In a lower part of the multi-part

The base body is then instead of the elastic damping element made of foam or plastic, according to the invention, the damping body made of compressed

Metal wire provided.

In particular in the context of such an embodiment, the damping body can be designed to be cylindrical. It must be taken into account here that the damping element can be formed solely by the damping body. In addition, however, it is also possible for the damping body to form the damping element together with at least one further layer or layer, with corresponding embodiments being described in more detail below. If the damping element has further layers or plies in addition to the damping body, this can also be done

entire damping element have a cylindrical shape.

According to an alternative embodiment of the invention, it is provided that the damping body is attached to the base body in a form-fitting manner. If, for example, the base body has a screw, in particular a carriage screw, the damping body can then be pressed in a form-fitting manner with a head of the screw. A simplified construction can then be achieved in a particularly advantageous manner. The damping body is held captive on the base body by such a form-fitting connection by pressing, with no intermediate elements in either

Form of a lower part or the like are necessary.

The form fit is provided to hold the damping body on the base body. When pressing with a lens-shaped head of a carriage bolt is then

for example a fixation along the longitudinal direction of the

Reached carriage screw, but the damping body is then rotatable relative to the carriage screw. Such rotatability is particularly advantageous because, in a conventional configuration of the base body, a height adjustment is possible by rotating the carriage bolt, even if the damping body rotatable with respect to the carriage bolt is already resting on a substrate while absorbing a partial load. A rotatable fastening of the damping body can also be expedient in alternative configurations, but in this case

a non-rotatable fixation can also be considered.

According to the configuration of a tub base known per se, the base body can have a fastening section, in particular with an internal thread, in which a screw shaft of the screw is received. By turning the screw in relation to the internal thread, a height adjustment is then possible in a particularly simple manner, as is the case when standing

the technique is described.

According to the invention, the damping element has at least the damping body formed at least partially from metal wire, although in principle multilayer designs are also possible. For example, it can be provided within the scope of the invention that the damping element has a plastic layer adjoining the damping body. In particular, an elastic layer and / or a sliding layer can be provided to modify the damping. Such additional layers are preferably made thin in comparison to the damping body. A sliding layer can be useful in order to make it easier to adjust the position of the support arrangement during assembly. In particular, a plastic can be provided,

which has a low coefficient of friction with common substrates

having. Furthermore, with regard to a movement of the support arrangement during assembly, there is also a

some mechanical protection of the metal wire.

The damping element can have an additional layer which adjoins the damping body. In addition, however, it can also be provided that additional materials are at least partially introduced into the cavities of the damping body formed from metal wire. For example, it is conceivable for the cavities remaining in the damping body to be at least partially through a

to fill in comparatively soft elastomer.

Due to the open structure of the damping body with metal wire, adjacent layers and sections of plastic can also be injected very easily, with at least partial penetration resulting in a very good

Anchoring can be achieved.

If, according to the embodiment described above, a separate plastic layer is arranged on the damping body, for example at least one adhesive can penetrate into the damping body itself in the manner described, so that a particularly reliable fastening then also achieved there

can be.

As described above, the damping element can also have materials other than metal wire in the form of additional layers and / or as a type of filling of the damping element. In addition, the metal wire can also be combined with other threads and fibers made of a non-metallic material during the manufacturing process.

For example, in addition to metal wire in one

Textile manufacturing process, in particular when knitting or warp-knitting, at least one further thread type can be provided. For example, threads made of polymers, in particular elastomers, natural fibers, carbon fibers, inorganic fibers, in particular glass fibers, or the like can be provided. It is also possible to provide several different thread types in addition to metal wire and / or to use one thread type which combines different materials in one thread. An example of this is known core-sheath threads or threads including metal wire

referenced a coating.

The advantages of the invention were previously explained using a tub base as an example. Accordingly, the

Invention also a support arrangement in the form of a tub base.

In principle, however, other support arrangements, in particular in the form of a trough anchor, are also possible. A conventional tub anchor with a base body and several damping elements is known, for example, from EP 1 219 218 B1, the known damping elements being formed from elastomeric plastic. According to the invention, based on such a configuration, at least one damping element can have a damping body formed from metal wire. Appropriately, starting from the known embodiment, all damping elements are formed with a damping body made of metal wire in order to achieve a particularly good decoupling on the one hand and a particularly good one on the other

Enable longevity. With regard to the further design options of a

Support arrangement in the form of a tub base or tub anchor

reference is made to the explanations above.

In the context of the invention, particularly good sound decoupling is achieved through the non-linear behavior of the damping body made of metal wire. In addition to a combination with additional materials, the geometry can also be changed to modify the damping and decoupling properties. Instead of a cylindrical or essentially cylindrical damping body in the manner of a solid cylinder, annular configurations or configurations with projections are also possible. In the case of an annular configuration, there is the advantage that the material of the damping element can deform both outwards and inwards. If, according to a variant of the invention, the damping element also has areas made of plastic in addition to the damping body, for example

individual support points made of plastic.

In addition to the support arrangements described in the form of a tub base or a tub anchor, other configurations can also be considered. For example, it is known to use flat elements made of hard foam in sanitary tubs as a carrier or as a central support. Such elements can then also move towards a floor, i.e. towards

be provided below the damping element.

Furthermore, the sanitary body, in particular in the form of a shower or bathtub, can also be supported only by a plurality of damping bodies, which then individually each form a support arrangement. A support can then without restriction in several places with damping bodies

take place, which have the base of conventional feet.

In principle, however, the damping body can also be used as a mat

or be designed as a kind of band.

If, according to a preferred embodiment described above, the support arrangement has the base body and the damping element adjoining it, the damping element can also be arranged between the sanitary body and the base body. Finally, starting from the base body in the direction of the sanitary body, a first damping element and in the direction of a floor or a surrounding wall a second damping element can be provided, which are designed as described above. It is also possible to shape the damping element with the damping body as required in order to attach it to a desired one

Fig. 1 shows a support arrangement in the form of a tub base for supporting a sanitary body. The sanitary body is preferably a bathtub, a shower tray or a shower surface. Such a sanitary body is usually supported by several tub feet which are either attached to a support frame or directly to the sanitary body. With regard to the possible configurations, reference is also made to the prior art mentioned at the beginning

referenced.

The tub base according to FIG. 1 has a multi-part base body 1 and a damping element 2 adjoining the base body 1. In the embodiment shown, the base body 1 comprises an upper housing 3 made of plastic, in which a male threaded part 4 is arranged. For height adjustment, a screw 5 in the form of a carriage bolt is provided, which is to be fixed in the desired position by a lock nut 6 acting against the male thread part. According to the usual configuration of the screw 5 as a carriage bolt, there is a head

7 provided with a lenticular underside. On the head

7, a lower part 8 of the base body 1 is clipped on, the lower part 8 forming a receptacle for the damping element 2. The screw 5 then has a square section 9 on the head, to which a tool is attached or

an adjusting wheel can be attached.

According to the invention, the damping element 2 has a damping body 10 formed from compressed metal wire 11. In the exemplary embodiment according to FIG. 1, the entire damping element 2 is completely formed by the damping body 10. Alternatives to this are given below

Refinements explained.

Metal wire 11 is formed.

Specifically, a knitted fabric is first formed with the metal wire 11 by knitting or knitting and then compressed to form the damping body 10. Despite the compression and the associated plastic deformation, individual loops of the knitted fabric can still be clearly seen in FIG. 3. Through the formation of the mesh, the wires are intertwined tightly, which also creates a compressed state

compact body is provided, from which also

can.

The formation of meshes is also particularly advantageous with regard to the desired elastic properties. On the one hand, according to the original mesh structure, many bends and bends remain, which cause elastic restoring forces, even in the compressed state. In addition, the stitch formation provides an open structure which, depending on the type of compression, also provides gaps and free spaces. The initial compression and the associated plastic deformation takes place with a suitable force, which is greater than the forces occurring during use. After the compression there is an elastic recovery, which is due to the springback of the individual arches, bends and angles as well as the

open macrostructure.

In this way, the damping body 10 becomes permanent

The metal wire 11 is in particular made of stainless steel in order to achieve a high level of durability over the long term. In the embodiment described, the meshes can, for example, have a height between 3 mm and 12 mm before compression

Even if a knitted fabric is particularly preferred as the starting material for the formation of the damping body 10, other arrangements such as a fleece are also fundamentally possible,

In FIG. 3 it can be seen that gaps still remain despite the compression of the metal wire. Thus, according to a preferred embodiment of the invention, the damping body 10 has a density between 2 g / cm * and 5.5 g / cm *. In relation to the entire volume defined by the outer surfaces of the damping body 10, the metal proportion is then typically between 25% and 70%, with

consequently between 75% and 30% are formed by gaps

is.

In the embodiment shown according to FIG. 3, the entire damping element 2 is formed exclusively from the damping body 10, which is made from compressed metal wire. In principle, the damping body 10 can also be combined with further layers or also partially filled, for which the following are examples

Refinements are further described.

FIG. 4 shows an alternative embodiment, with the lower part 8 being omitted based on a matching embodiment of the base body 1. The damping body 10 is positively pressed with the head 7 of the screw 5, so that a structural simplification results. In this connection, it can be seen from FIG. 5 that the damping body 10 engages around the head 7. For better illustration, a sectional illustration is also shown in FIG. 6. The damping body 10 can be rotated with respect to the head 7, so that the screw 5 can still be turned slightly for height adjustment even when the damping body is already below

Taking up a partial load rests on a surface.

From a comparative consideration of FIGS. 3 and 4, it can already be seen that the shape of the damping body can be varied. While according to FIG. 3 the damping body 10 is designed as a circular cylinder, according to FIG. 4, in addition to the form-fitting attachment to the head 7 at the edges of the damping body 10, a bevel is also provided, whereby the damping body 10 can be moved more easily on a surface, for example . A modification of the geometry of the damping body 10 can finally also be used to influence the support and

Damping effect can be provided.

In this context, Figures 7A to 7E show examples of possible variations, which are also further modified

and some can also be combined.

According to FIG. 7A, the damping body 10 has on its

An annularly protruding support surface 12 on the underside.

According to FIG. 7B, the damping body 10 is designed as a whole ring-shaped. In the event of a load it can then

deform the damping body 10 inwards and outwards.

According to FIG. 7C, the damping element 2 has a plastic layer 13 in addition to the damping body 10. The plastic layer 13 can be formed from an elastomer, for example, in order to modify the damping properties. Additionally or alternatively, the plastic layer 13 can also be provided as a type of sliding layer. In practice, such a plastic layer 13 can also be injected particularly easily and reliably. Even with the use of adhesive there is the advantage that it is in the

Damping body can penetrate.

According to FIG. 7D, the damping body 10 is provided with a plastic filling 14 in the lower area. It can be a comparatively soft elastomer, for example

act.

According to FIG. 7E are on the underside of the damping body

10 individual support points 15 made of elastomer.

The structures formed in FIGS. 7A to 7E by the damping body 10 itself and / or by an additional material of the damping element 2 can be varied and modified even further in order to modify the decoupling properties. For example, in a modification of the embodiment according to FIG. 7A, several, in particular concentric, rings can also be formed from the damping body 10 or the additional material

be.

8 shows by way of example that the support arrangement can also be provided in the form of a tub anchor, for example. A base body 1 is formed from sheet metal, a total of three damping elements 2a, 2b, 2c being provided, each of which comprises a damping body 10a, 10b, 10c

have compressed metal wire.

FIG. 9 shows, purely by way of example, force-displacement diagrams for a damping element 2 according to the invention in comparison with the prior art. The embodiment according to the invention is represented by curve B, while curve A is the state of the art

Technology.

Based on a typical thickness between 2 mm and 20 mm, the compression permitted in practice is between approximately 0.3 mm and a few millimeters, for example approximately 1 mm, in order to avoid damage to sealing transitions and sealing joints under all circumstances when the support arrangement is loaded to avoid. In the case of conventional damping materials based on elastomers, with comparatively small deflections, an approximately linear course results, as shown by curve A. It should be noted that the maximum permissible force Fmax occurs, for example, when, in the case of a support arrangement in the form of a tub base, practically the entire weight of a user rests on the corresponding tub base. This is the case, for example, when a user stands on the edge of a shower tray or shower surface exactly above the corresponding tub base. To support a shower tray or shower surface, several tub feet are provided in practice. If a tub foot is only provided at each corner of a rectangular sanitary body, then the total force of a user is then distributed evenly over at least four tub feet. Usually, however, more than four tub feet are arranged around the circumference of the sanitary body, so that when the load is uniform, the force action is even further reduced compared to the maximum permissible force action Fmax. However, in order to avoid excessive deformation at the maximum permissible force Fmax, according to the prior art, the damping elements formed on the basis of elastomer must have an essentially linear characteristic curve

be executed relatively hard.

The damping element 2 according to the invention with the damping body 10 based on metal wire, on the other hand, is distinguished by a strongly non-linear behavior. According to curve B, such a damping element 2 is initially comparatively soft and resilient, with a particularly soft elastic behavior and thus usually also good decoupling being possible with a low force load, in particular with a uniform force distribution. The force then rises disproportionately only shortly before the maximum permissible deformation is reached. The illustration in FIG. 9 also has the advantage that, according to the present invention, a sanitary facility is even better protected against damage if the specified maximum load is unexpectedly reached

Fmax is exceeded.
