The adhesive can cure there together with a prefixing element and adhesive element which is designed to prefix the fastener to a support surface with immediate adhesive action.

Description

fasteners

The invention relates to a fastener.

Such fasteners may in particular be designed as a hinge fastener, which are used in particular to attach a toilet seat to a ceramic part, that is, a toilet bowl. In known hinge fasteners screw connections are provided to couple a toilet seat via a hinge to a ceramic part. For this purpose, it is necessary to introduce holes in the ceramic part, in order then to anchor in these the necessary screws.

The disadvantage here is, on the one hand, that, when holes are made in the ceramic part, there is the danger that cracks will occur in the ceramic part. The ceramic part must either be laboriously repaired or even disposed of, as it has become unusable.

Another disadvantage is that the assembly of such systems is undesirably expensive. For the production of screw connections required threaded parts must be screwed mainly to the underside of the ceramic part, that is, the operator must perform the screw connection from below to a toilet, which on the one hand is very uncomfortable and also makes a forced length overhead during assembly required ,

Finally, there is a significant disadvantage in that the maintenance of the screw connections is often poor, with the screw loosening connections in particular over time by the mechanical stresses. The result is wobbly toilet seats. With a stronger wear is also Slipping of the toilet seat to the ceramic part possible, which can lead to entrapment in the use of the toilet.

Finally, it is disadvantageous that unhygienic dirt deposits can form on the numerous mechanical individual parts for forming the screw connections.

Corresponding problems also occur with other fasteners, which are used for example for attachment of accessories on.

The invention has for its object to provide a hinge fastener of the type mentioned, which can be mounted easily and safely and has high functionality.

To solve this problem, the features of claim 1 are provided. Advantageous embodiments and expedient developments of the invention are described in the subclaims.

The fastener according to the invention with an equipment module has a receptacle for an adhesive, which is adapted to cure in a gas- and liquid-tight enclosure. The adhesive may cure there with a prefixing member and an adhesive member configured to pre-fix the fastener to a support surface with an immediate adhesive action. A significant advantage of the fastener according to the invention is that with the adhesives a firm and permanent attachment of the equipment module is made possible on the support surface, being particularly advantageous that this can be dispensed with previously required screw connections. Thus, no holes must be incorporated into the support surface for fixing the fastener, so that there is no longer any risk of damage to the support surface. Another essential advantage of the invention is that the fastener according to the invention, in addition to the adhesive, which ensures a firm, permanent fixation of the fastener on the support surface, a Vorfixier- element is provided with which an immediate prefixing is achieved. The prefixing can be fixed quickly and without tools on the support surface, which immediately adheres to the support surface with the adhesive element.

Advantageously, the adhesive element is formed by an adhesive film or an adhesive tape. The prefixing element can be mounted with exact position at the desired location of the support surface, that is, the prefixing element thus also forms a positioning means for aligning the fastener on the support surface.

For this purpose, the prefixing element is particularly advantageously designed as a fixing ring.

The prefixing element ensures prefixing of the equipment module to the support surface in the desired position. In this case, an adhesive effect is achieved with the adhesive element, which then ensures a secure hold of the equipment module on the support surface when it is perpendicular or inclined, so that the equipment module is pulled away by gravity down and thus from the support surface.

Furthermore, a tool-free mounting option of the equipment module is given on the Vorfixerelement particularly advantageous. The equipment module then has to be expediently attached, snapped or clipped onto the prefixing element. This eliminates cumbersome tool-bound fixations, such as attaching the equipment module on Vorfixierelement with screws. Another advantage of the invention is the formation of the adhesive in the form of an aerobic adhesive, which is particularly advantageously formed by silane polymers.

This aerobic adhesive is inventively combined with a hydrophilic substance and / or a flowable material, in particular a liquid, whereby it is achieved that the adhesive can cure in gas and liquid-tight encapsulations.

According to a first variant of the invention, the aerobic adhesive forms a mixture with a hydrophilic substance to which moisture has been added in metered quantities, the hydrophilic substance preferably being formed by a hydrophilic carrier fiber, in particular cotton.

The addition of the hydrophilic substance to the aerobic adhesive results in a mixture that no longer has to be brought into surface contact with moist ambient air in order to then harden from this surface. Rather, the existing in the mixture, the aerobic adhesive enforcing hydrophilic material ensures that the aerobic adhesive contained in the mixture can harden from the inside even when no external contact with the moisture-containing ambient air is given more. The moisture or oxygen required for curing is present in the hydrophilic substance itself, since due to its hydrophilic properties it contains enough moisture that is needed for the curing of the aerobic adhesive in the mixture forming the fastener.

Depending on the application, the moisture content of the hydrophilic substances may not be high enough to ensure complete curing of the mixture after mixing with the aerobic adhesive, since the hydrophilic substances release their moisture to the environment depending on the ambient conditions or absorb moisture from the environment. However, the amount of moisture in the hydrophilic substance or in the mixture of the hydrophilic substance with aerobic adhesive is of great importance. Too much moisture destroys the bond, too little moisture leads to no reaction in the aerobic adhesive, which is formed in particular by polymers, so that curing does not occur.

In order to obtain the appropriate moisture content in the mixture, moisture is metered into the mixture of aerobic adhesive and hydrophilic substance. Particularly advantageous is a metered addition of moisture to the hydrophilic substance before it is mixed with the aerobic adhesive.

Particularly suitable for a metered supply of liquid is a spatula made of wood, which is used for mixing the components and which is previously dipped in water or in general in a liquid amount. The amount of water, or generally the amount of liquid that the spatula can hold, forms a metered amount of moisture that is supplied to the mixture of aerobic adhesive and hydrophilic matter. In this case, the hydrophilic substance can act as a moisture buffer that can absorb excess moisture and release it again when needed. Through the mixing process, the moisture gets into the entire volume of the mixture, which allows it to fully harden. Alternatively to a spatula, other liquid feeders may be used. In principle, the use of encapsulated elements containing liquid, possible. These burst during the mixing process and then pour the liquid into the mixture. By adding the encapsulants as well as adding the hydrophilic substance, the tensile and shear strengths of the adhesive can be improved. In principle, storage granules can also be added to the hydrophilic substance as a moisture reservoir.

According to a second variant of the invention, a means for generating a height-profiled layer of aerobic adhesive is provided, wherein this is provided by a surface layer formed by a flowable material. By pressing in the equipment module, volume deposits of the flowable substance in the aerobic adhesive are formed on the bearing surface with the layer structure thus formed. Advantageously, the flowable material consists of a hydrophilic or hygroscopic substance.

A significant advantage of this variant is that for the production of the adhesive, the mixing of the aerobic adhesive with the flowable material can be completely eliminated, whereby the handling of the fastener for establishing a connection between an article and a pad is considerably simplified.

The mixing process of the flowable material with the aerobic adhesive to form the adhesive rather takes place automatically when the article is pressed onto the support surface. The prerequisite for this is that the aerobic adhesive is applied in the form of a height-profiled layer, which differs from a flat layer through the formation of height structures separated by valleys. The height differences can vary in their absolute amount in a wide range and be formed and distributed homogeneously or inhomogeneous. The then applied to the height profiled layer of the aerobic adhesive surface layer of the flowable material may be formed either homogeneous or inhomogeneous. In this case, the surface layer of the flowable material may advantageously extend over the entire surface of the height-profiled layer of the aerobic adhesive, but this is not mandatory.

Then the article is placed on the layer structure thus formed, consisting of the height-profiled layer of the aerobic adhesive and the surface layer of the flowable material to the article on the base ge to fix, the tips of the height-profiled layer are transferred by the contact pressure of the article in the direction of the valleys of this layer, whereby the flowable material in the volume of the aerobic adhesive is stored, that is mixed with this, without the need for a separate operation is.

By enforcing the aerobic adhesive with the flowable fabric so that the adhesive can cure quickly in its entire volume, without the need for contact with the outside atmosphere or external fluid supply would be necessary. In particular, the fastening means according to the invention can be used between two diffusion-proof surfaces in order to connect them.

According to a particularly advantageous embodiment, the flowable substance is in the form of a liquid. Particularly advantageously, the liquid consists of a hydrophilic substance such as polyethylene glycol. Also suitable as hydrophilic or optionally hygroscopic liquids are polypropylene glycol, an oxygen solution, an alcohol, in particular isopropanol as a mixture with water. In general, the hydrophilic liquid or generally the hydrophilic substance serves to react with the aerobic adhesive by exchanging moisture, oxygen, hydrogen, carbon and other reactants. In principle, the liquid can also be formed by water.

According to a third variant of the invention, the aerobic adhesive is applied to a hydrophilic insert, which is metered moisture supplied.

Advantageously, the hydrophilic insert in the form of a plate-shaped insert consisting of cotton or a fiber composite material, or in the form of a sintered plate, or in the form of a hydrophilic coating formed on a liner body. An essential aspect of this is the interaction of the aerobic adhesive with the hydrophilic insert. As a result of the contact of the aerobic adhesive with the hydrophilic insert, which contains moisture in a metered manner, the aerobic adhesive cures in its entire volume without requiring contact with the ambient air.

This aerobic adhesive, which interacts with the hydrophilic insert, provides a durable, reliable and, above all, readily available attachment of objects, without any use of screws and similar mechanical fasteners. Another important advantage is that it is no longer necessary to mix an aerobic adhesive with a hydrophilic substance. Rather, only the mechanical contact of the aerobic adhesive to the hydrophilic insert, which is given when applying the aerobic adhesive to this hydrophilic insert, to ensure complete curing of the aerobic adhesive in completely gas and liquid-tight encapsulation of the aerobic adhesive. A time-consuming mixing of an aerobic adhesive with a hydrophilic substance is thus eliminated, whereby a high ease of installation of the fastener is given.

The fastener according to the invention can be designed in different configurations for use in correspondingly different applications.

An essential aspect consists in the fact that the equipment module is designed to accommodate different application-specific parts.

The equipment module thus forms an application-unspecific and therefore universally applicable element that can be used in various applications. The adaptation to specific applications can be achieved by a modular kit system by combining the equipment module with different application-specific parts. According to an advantageous embodiment of the invention, the fastener is formed by a mounting plate for accessories.

According to a further advantageous embodiment of the invention, the fastener is designed as a hinge fastener. The hinge fastener is particularly advantageous for attaching a toilet seat to a ceramic part, that is, a toilet bowl, used, being achieved via the hinge parts an articulated, pivotal mounting of the toilet seat on the ceramic part.

By using the adhesive according to the invention instead of screw connections, the mounting of the hinge fastener on the ceramic part is considerably simplified, since now the hinge fastener can be mounted from the top of the ceramic part, that is inconvenient over-head mounting positions omitted. Also, the hinge fastener can be easily and without residue loosened back from the ceramic part as needed. Another important advantage is the specific design of the adhesive as an aerobic adhesive, which cooperates with a hydrophilic insert, which contains dosed moisture.

The hydrophilic insert forms with the equipment module of the hinge fastener a structural unit, which only the aerobic adhesive must be supplied to unfold the necessary adhesive effect and so as to mount the hinge fastener on the support surface.

The aerobic adhesive and the hydrophilic insert are advantageously encapsulated gas and liquid tight in the cavity between the support surface and the equipment module of the hinge fastener. Thus, the curing process of the aerobic adhesive within the enclosure is completely independent of the ambient conditions and is therefore highly reproducible. Particularly advantageously, the hydrophilic insert is in the form of a coating, which may consist of the aforementioned substances. This coating can be applied without significant application of material specifically to interfaces of the module, in particular the Passtellers, these interfaces form contact surfaces with the support surface. Then only the aerobic adhesive needs to be applied to this coating in order then to fasten the hinge fastener to the support surface.

According to an advantageous embodiment, a fixing ring is provided as a further component of the equipment module as Vorfixierelement, by means of which an additional leakage of adhesive is prevented.

This fixation also supports the gas and liquid-tight encapsulation of the adhesive within the equipment module.

In principle, the equipment module can already form a gas-tight and liquid-tight encapsulation by integrally forming the adhesive base and the adjuster.

Alternatively, the adhesive base and the Passteller can form a gas-tight connection.

For this purpose, the adhesive base may have an adapted to the Passteller conical form-closing or pass-end.

Likewise, the adhesive base may have a positive fit for connection to the Passteller.

The connection between Passteller and the hinge part can be realized accordingly by a positive, fit and / or non-positive connection. This connection can be formed centrally in the equipment module and thus define a fixed mounting position of the hinge parts. Alternatively, you can be realized by an eccentric mounting in Passteller an adjustment of the hinge parts.

Furthermore, a clip connection can be provided for fastening a hinge part on the module. This allows a quick and easy attachment of hinge parts on the equipment module of the hinge fastener.

According to an advantageous embodiment of the invention, a hinge part is formed integrally with a component of the equipment module.

As a result, a hinge fastener with very few individual parts is obtained, which is accordingly easy to assemble.

For a positionally accurate mounting of the hinge fastener and a correspondingly accurate alignment of the hinge parts is achieved, whereby these form exactly aligned parts for receiving a toilet seat.

According to an advantageous development of the invention, the hinge fastener may have a screw fastening as an additional fastening possibility. The hinge fastener can then be screwed to the ceramic part as an alternative or in addition to the adhesive bond, which is advantageous for manufacturers of ceramic parts that can not dispense with hole formations in these ceramic parts. The invention will be explained below with reference to the drawings. Show it:

Figure 12, 13: embodiment of a fastener in the form of a shower profile.

Figure 1 shows a ceramic part 1, which forms a sanitary ware in the form of a toilet bowl. For hinged attachment of a toilet seat not shown separately, two hinge fasteners 2 are fastened on the upper side of the ceramic part 1, wherein only one of these hinge fasteners 2 is shown in FIG.

The hinge fastener 2, the components of which are shown in an exploded view in FIG. 2, has a module 3 forming a universal structural unit, which generally forms an equipment module and on which different hinge parts 4 can be mounted, in order to adapt them to different (WC Seats).

As can be seen from FIG. 2, the module 3 of the hinge fastener 2 has an annular adhesive base 5, a fitting plate 6 which can be inserted into it, and a clamping ring 7 for fixing the abovementioned parts. All components of the module 3 are made of gas- and liquid-tight material. For example, all components of the hinge fastener 2 made of stainless steel, chrome-plated brass, aluminum, optionally chrome-plated plastic or other ferrous and non-ferrous metals. The Passteller 6 is formed in the present case as a conical actuator, which forms a positive connection with the adhesive base 5, that is, the adjacent lateral surfaces of the Passtellers 6 and adhesive base 5 have adapted to each cone shapes. Alternatively, a threaded connection between the adjuster 6 and the adhesive base 5 can also be provided, that is to say a thread is provided on the inner circumferential surface of the adhesive base 5 and on the outer circumferential surface of the adjuster 6. By tightening the clamping ring 7 with a key or the like, the fitting plate 6 in the adhesive base 5 as well as the hinge parts 4 in the fitting plate 6 are positively fixed with each other and firmly connected. The clamping ring 7 has for this purpose on the outside of a polygonal structure 7a or possibly a perforation or other structures, which serves as a drive, by means of which the key can engage the clamping ring 7 and drive it. The outer circumferential surface of the adhesive base 5 and the inner circumferential surface of the clamping ring 7 are adapted to one another in their geometries and lie against each other light. To form the positive connection with the Passteller 6, the hinge part 4 a fitting ring 8 which engages positively into a bore 9 of the adjuster 6. The fitting ring 8 is formed integrally with the hinge part 4.

FIG. 3 shows the fitting plate 6 used in the adhesive base 5 and a plurality of hinge parts 4, 4a, 4b which can be mounted in the bore 9 of the fitting plate 6. The first hinge part 4 with the integrally formed fitting ring 8 corresponds to the embodiment according to FIG. 2. Furthermore, FIG. 3 shows two angled hinge parts 4a, 4b to which a separate fitting ring 8a is assigned. To fix such a hinge part 4a, 4b, it is inserted into the bore 9 of the adjuster 6 and then pressed with the fitting ring 8.

The hinge fasteners 2 are placed for fixing on the ceramic part 1 on its upper surface forming a support surface and then fixed by means of an adhesive bond. Figures 2a, 2b show two embodiments of such an adhesive bond.

In the embodiment according to FIG. 2a, a hydrophilic insert in the form of a hydrophilic coating on the underside of the adhesive base 5 facing the bearing surface is applied as the first component for forming an adhesive. The hydrophilic coating 10 is at least partially made of a fiber composite or cotton. This hydrophilic coating 10 is metered moisture supplied, for example by passing a moistened cloth over the coating. An aerobic adhesive 11, which is preferably formed by silane polymers, is applied to this hydrophilic coating 10. Then the module 3 of the hinge fastener 2 is placed on the support surface. By the module 3, the adhesive thus formed gas-tight and liquid-tight encapsulated. The moisture in the hydrophilic coating ensures that the aerobic adhesive 11 can cure in its entire volume.

The embodiment according to FIG. 2b shows the fitting plate 6 inserted into the adhesive base 5. A hydrophilic plate 10a is fastened to the underside of the fitting plate 6. The hydrophilic plate 10a is at least partially made of cotton or a fiber composite material. Alternatively, the hydrophilic plate 10a may be in the form of a sintered plate made of plastic, stainless steel or brass. Analogously to the hydrophilic coating according to FIG. 2a, moisture is also metered into the hydrophilic plate 10a. On the underside of the hydrophilic plate 10a, an aerobic adhesive 11 is applied, which is formed analogously to the embodiment according to FIG. 2a. Then, the module 3 of the hinge fastener 2 is placed on the support surface of the ceramic part 1. Through the module 3, the adhesive is gas-tight and liquid-tight again encapsulated. The moisture in the hydrophilic plate 10 ensures that the aerobic adhesive 1 1 can cure in its entire volume. By the adhesive connections as shown in FIGS. 2 a, 2 b by way of example, the hinge fastener 2 can be fastened to the ceramic part 1 without incorporation of holes. The adhesive bonds can be removed without residue at any time by twisting off the hinge fastener 2.

Figures 4 and 5 show a further embodiment of the hinge fastener 2. There, the optionally integrally formed unit of Passtellers 6 and the adhesive base 5 is shown. Figures 4, 5 further show a hinge part 4c, at the lower end of a locking element 12 is provided. This locking element 12 can be clipped into the bore 9 of the Passtellers 6. A locking bolt 13 is used to fix the Passtellers 6 on the adhesive base. 5

Furthermore, the arrangement of Figures 4, 5, a self-adhesive position gauge 14, which can be adhered to the ceramic part 1. This is associated with a marking 15 on the outer circumferential surface of the adhesive base 5. With these elements, a highly accurate alignment of the hinge fastener 2 is made possible.

Figure 6 shows a modification of the embodiment in that the hinge part 4 with the Passteller 6 forms a unit. The locking bolt 13 is again used to fix the Passtellers 6 on the adhesive base. 5

FIG. 7 shows an extension of the embodiment according to FIG. 6 in that in addition a fixing ring 16 is provided, which consists for example of double-sided adhesive tape. This fixing ring 16 serves to pre-fix the Schamierbefestigers 2 on the ceramic part 1 without gluing time and also prevents leakage of aerobic adhesive 11, which is applied in the present case on a arranged on the underside of the inserter 6 hydrophilic plate 10 a. Figure 8 shows an embodiment in which the hinge part 4d again forms a unit with the Passteller 6. In the top of Passteller 6 long holes 17 are incorporated. In the associated adhesive bases 5, on which the adhesive is provided, threaded bores 18 are provided. This allows the Passteller 6 are screwed to the adhesive base 5.

Figure 9 shows an embodiment in which the module 3, which consists of adhesive base 5 and Passteller 6 and on which a hinge part 4e is attached, glued to the ceramic part 1 and additionally also can be screwed there. This represents a development of the embodiment of Figure 8 such that a screw 19 passes through a slot 17, 17a in the module 3 and then inserted into a bore 9 of the ceramic part 1, whereby the hinge fastener 2 is screwed to the ceramic part 1.

FIGS. 10 and 11 show an adhesive application aid 21 associated with the module 3 of the hinge fastener 2, which preferably also forms the position sleeve 14 of FIGS. 4, 5. The adhesive application aid 21 essentially forms a shadow mask and thus facilitates an exact, positionally accurate application of the aerobic adhesive 11. In addition, this prevents undesired adhesive leakage.

Figures 12 and 13 show a fastener in the form of a shower profile 22. The shower profile 22 has the shape of a U-profile, wherein Figure 12 show the back and Figure 13 shows the front of the shower profile.

As shown in FIG. 12, the rear side of the shower profile 22 has a flat surface 23, which is delimited at both lateral edges by a respective groove 24. The grooves 24 run parallel and at a distance from each other. The outer walls of the grooves 24 form bearing surfaces for a prefixing element on their upper sides.

As can be seen from FIG. 12, an application of adhesive takes place on the flat surface 23 of the shower profile 22, wherein the grooves 24 carry excess adhesive. tel record, so that when fixing the shower profile 22 on a wall or the like side no adhesive occurs.

The adhesive in turn comprises an aerobic adhesive which is discharged from a tube 25. At the outlet of the tube 25 is a head 26 with a toothed spatula 27. By thus formed head 26 is a height-profiled adhesive layer 28 is applied to the flat surface 23. In the tube 25 can also be stored separately as flow-capable substance water, so that metered with the tube 25 and water is sprayed onto the height-profiled adhesive layer 28. After the order of the so-formed adhesive the shower profile 22 is pressed with its back against a wall. As a result, the height-profiled adhesive layer 28 is pressed together and the sprayed-on water is distributed in the volume of the aerobic adhesive, so that it can cure even with gas and liquid-tight encapsulation. The prefixing agents at the edges of the backside prevent premature peeling of the showering profile 22 during the curing of the aerobic adhesive.

As FIG. 13 shows, to accelerate the curing process on the front side, a heating element 29 can be placed, which in the present case is formed by a silicone heating element. In principle, it is also possible to dispense with the prefixing agent in this evaluation. List of Reference Signs
