Arrangement and procedure

description

The invention relates to a fastening system for a toilet seat according to the preamble of claim 1, a cage, a cage nut, the use of a fastening means for such a fastening system, an arrangement comprising a toilet seat and a fastening system and a method for fixing a toilet seat.

An attachment system of the type mentioned is known for example from EP 2 150 657 AI. When installing toilets, a final step is the attachment of a toilet seat to a pool body. Conventional toilet seats for this purpose have two hinges, which are pivotally connected to the seat and are connected to respective fastening systems, which are attached to the toilet bowl.

The hinges are fixedly spaced on the toilet seat. The distance between the attached to the toilet bowl attachment systems must therefore match exactly with the distance between the hinges. This distance must be during the installation of the WC or when changing the

Toilet seat can be adjusted exactly. It is also aesthetically necessary to be able to adjust the position of the fastening systems so that the toilet seat is flush with the pelvic body.

The fastening systems known in the art are perceived in their handling and possibility of adjustment described above as insufficient.

The fastening system known from EP 2 150 657 A1 comprises a cage in which a simple square nut is arranged. The square nut is bolted to a hinge pin connected to the toilet seat. The square nut strikes the cage and transfers the tightening torque this. The square nut allows only limited alignment movements, so that the assembly is complicated and time consuming, which leads to increased costs and possibly an unsatisfactory assembly result. The present invention is based on the object, the well-known

Mounting system for easier installation and increased flexibility in positioning the toilet seat to improve. The invention is also based on the object, a cage, a cage nut, the use of a

A fastener for such a fastening system, an arrangement comprising a toilet seat and a fastening system and a method for fixing a toilet seat specify.

This object is achieved by a fastening system according to claim 1. The object is with regard to the cage by the subject-matter of claim 14, with a view to the cage nut by the subject-matter of claim 15, with a view to use by the subject-matter of claim 15, with regard to the arrangement by the subject-matter of claim 17 , And with regard to the method for fixing a toilet seat by the subject of claim 18 solved.

The invention is based on the idea to provide a fastening system for a toilet seat, which comprises a cage which is connectable to a toilet bowl. The fastening system further includes a cage nut received in the cage and threaded. In the thread a fastener for the toilet seat is screwed or screwed. The cage nut has at least one profile projection, which has a

Outer surface of the cage nut projects and engages in a slot of the cage. The slot is adapted to the profile projection.

The invention has the advantage that the torque transmission and the

Positioning of the cage nut and thus in the cage nut

screwed or screwed fasteners for the toilet seat are largely decoupled. For this purpose, the at least one profile projection on the cage nut is provided, which projects beyond an outer surface of the cage nut and engages in the slot adapted to the profile projection of the cage. The non-rotatable mounting of the cage nut thus does not occur through the circumferential profile the square nut, but by an additional profile projection which projects beyond an outer surface of the cage nut and cooperates with a correspondingly adapted slot in the cage. By combining the

Profile projection and the slot is achieved that the profile projection strikes when screwing and / or tightening the fastener on the inside of the slot and prevents twisting of the cage nut. Of the

Profile projection acts as a rotation-inhibiting element. On the

Profile projection, the tightening torque of the fastener is transferred to the cage, without the cage nut is completely blocked in the cage. Thus, an improved freedom of movement of the cage nut is achieved in the cage, which facilitates the positioning of the toilet seat with loosely screwed fastener. In addition, the profile projection allows some guidance of the cage nut in the cage when aligning the toilet seat. It is possible to provide a plurality of profile projections, which are arranged distributed on the circumference of the cage nut.

Preferably, the fastening means is a threaded bolt with a

Connector for the toilet seat, specifically designed for the hinge of the toilet seat.

The connection of a toilet lid can be done in the usual way.

Preferably, the at least one profile projection on the outer edge of

Cage nut arranged. Due to the arrangement of the profile projection on

Outside edge is the available space in the cage for the

Alignment movement of the cage nut optimized.

Specifically, the profile projection can be designed as a nose, which is located in the

Substantially coaxial with the central axis of the cage nut extends. In other words, the nose protrudes substantially perpendicularly over the end face of the cage nut. There may be several appropriately trained noses

be provided. In a preferred embodiment, the inner diameter of the cage is greater than the outer diameter of the cage nut, so that a good

Radial mobility of the cage nut is achieved in the cage. Specifically, that is Inner diameter of the cage larger than the outer dimensions of a geometric basic shape of the cage nut, which may be, for example, cylindrical. The cage nut can thus move relatively freely in relation to its basic shape in the cage. The non-rotatable mounting allows the screwing of the fastener in the cage nut, while the simultaneous displaceability of the cage nut allows adjustment of the position of the fastener in the loose screwed state. It is thus possible in a simple way, the position of

Adjust fastener so that when connecting the toilet seat with the mounting system, the geometry of the toilet seat can be considered. The fastening system may also be positioned in the cage due to the displaceability of the cage nut so that the edge of the built-in toilet seat is flush with the underlying toilet bowl.

Preferably, the cage nut has a cylindrical basic shape with a radially projecting projection, wherein the profile projection is arranged on the projection. This has the advantage that the profile projection can be spaced further from the central axis.

In one embodiment, the cage has a stop for receiving the cage nut. This prevents the cage nut from slipping out of the cage when it is inserted. This simplifies the handling of the system and leads to an accelerated assembly process.

In a (further) embodiment, the cage is with a screw,

in particular with the head of a screw engageable. The screw can be screwed into the pelvic body. This provides a simple way to connect the attachment system for the toilet seat with the pelvic body. The screw on the one hand and the fastener on the other hand are arranged on opposite sides of the cage, which thus creates the connection between the pelvic body and toilet seat in the assembled state.

In a preferred embodiment, the screw and the cage in the engaged state are radially movable relative to each other. This further increases the flexibility of the fastening system. In a concrete embodiment, this is realized in that the underside of the cage has a laterally open, has slot-shaped recess with locking lugs, in which the screw, in particular the head of the screw is laterally inserted such that the latching noses hold the screw slidably in the slot of the cage. This leads to a simplified assembly, since the cage can be attached by simply plugging.

In one embodiment, upper and lower surfaces defining a space for receiving the cage nut are each coaxial

Passages on. As a result, even with inserted cage nut, a screw which is engaged with the lower part of the cage, accessible.

In a preferred embodiment, the cage nut by a with

Plastic molded mother formed. This allows easy manufacture of the cage nut including the profile projection.

The profile projection and the plastic material surrounding the nut are integral, i. monolithic trained.

To encapsulate a plastic material, preferably a thermoplastic is used. This gives the encapsulation of the cage nut a certain

Flexibility, while a sturdy metal thread for screwing the

Fixing screw is provided. If the fastener is stuck

tightened, the cage nut is pressed against the cage and fixed due to the deformable plastic against the cage. Thus, the toilet seat in the assembled state can not be moved.

In a preferred embodiment, the cage nut has at one end face a flange arranged at the periphery of its opening, which is loosely engaged with the upper passage opening of the cage, so that the cage nut in the cage is radially movable. The flange can serve as a (further) guide element for the fastener to be screwed in and simplifies the assembly.

In a preferred embodiment, the fastening means comprises a

Thread, by means of which it can be screwed into the cage nut, and a pin with which a toilet seat is connectable. Concretely, therefore, the attachment means may be formed as a threaded bolt, the connection piece is designed for the toilet seat as a pin or profile pin. An associated with the toilet seat Hinge can be attached to the pin or the profile pin. This represents a very simple assembly process.

Preferably, the fastening means has a stop limit for a hinge plate, which can be pushed onto the fastening screw. The hinge plate serves to cover a recess in which the cage

is recorded and improves the overall aesthetic impression. Since the hinge plate is merely pushed onto the fastening screw, it is still movable before the final tightening of the fastening screw, so that the precise adjustment of the position of the fastening system is simplified.

Alternatively, the hinge plate can be screwed onto the fastening means and indeed onto the thread of the fastening means, which can be screwed into the cage nut.

In a further embodiment, the thread of the fastening means is a special thread, which is designed such that it is in a corresponding

Special thread of the cage nut can be screwed. The special thread can have a thread size of M8,85. The slope can be 1.25.

The invention further provides a cage for use in a toilet seat attachment system. The cage is designed to receive a cage nut and has a slot which can be brought into engagement with a corresponding profile projection of the accommodated cage nut. With the cage according to the invention, the assembly of the

Fixing system simplified.

The invention also provides a cage nut for use in a toilet seat attachment system. The cage nut has a profile projection which is engageable with a corresponding slot of a cage.

In the context of the invention, the use of a fastening means for a fastening system according to one of claims 1 to 13 is disclosed and

claimed, wherein the fastening means is a thread for a cage nut and a pin on which a toilet seat is attachable, and together with the cage nut allows alignment of the toilet seat.

The invention according to the independent claim 17 comprises an assembly comprising a toilet seat and a fastening system according to any one of claims 1 to 13, wherein the toilet seat with the fastening means

connectable or connected. The toilet seat is an essential element of the arrangement according to the invention and can be used alone or together with the

Fastening system be offered.

The toilet seat is adapted for connection to the fastening system according to one of claims 1 to 13. For this, the toilet seat has a

Connection possibility for the fastener, specifically the threaded bolt, on. The connection option can be a receptacle for the pin or the profile pin of the threaded bolt. The fastening means or the threaded bolt is screwed into the cage nut of the fastening system according to claim 1, so that in the assembled state, the inventive arrangement of toilet seat and fastening system results. In the context of the invention, a method for mounting a toilet seat with the fastening system according to the invention is specified, comprising the following steps:

Inserting a cage nut into a cage such that a profile projection of the cage nut engages a slot of the cage;

Connecting the cage to a pelvic body;

Screwing a fastener into the cage nut; Adjusting the position of the fastener;

- tightening the fastener; and

Connecting a toilet seat with the fastener.

The inventive design of the fastening system high flexibility in the adjustment of the position of the fastener is achieved with the toilet seat is connected. It is thus ensured that the toilet seat can be mounted quickly and aligned with high accuracy to the pelvic body. Preferably, the connection of the toilet seat with the

Fastening means by attaching a fastened to the toilet seat hinge on the fastener. This makes the installation uncomplicated.

The invention will be described with further features and advantages with reference to an embodiment, which is explained in more detail with reference to the accompanying figures.

Fig. 5 shows a fastening means for a toilet seat and a

Hinge plate for use in the fastening system of FIG. 1.

In Fig. 1, a toilet seat attachment system according to an embodiment of the invention is shown. The fastening system comprises a cage 10 in which a cage nut 20 is received, in turn, a fastening means 30 is screwed for a toilet seat. In the following the components are described in detail. The term "above" refers to a side of the respective component facing the toilet seat, referred to the cage or cage nut. "Bottom" refers to the cage or cage nut and refers to a side of each component facing the bowl body. The statements "top / bottom" are therefore to be understood in the installed state. [0022] FIG. 2a shows a perspective view of the cage 10 according to FIG

Embodiment of the invention. The cage 10 is made of plastic. Its outer contour is essentially cylindrical. The cage 10 has at its upper end a space 13 with a lateral opening 43, through which a cage nut 20 described below can be inserted into the cage 10. The inner dimensions of the opening 43 are slightly larger than the outer dimensions of

Cage nut 20.

The space 13 is delimited at the top by a radially inwardly directed annular projection 42 extending in the circumferential direction of the cage 10 and having an upper passage opening 14a, in particular a circular upper one

Passage opening 14a, defined.

The annular projection 42 is interrupted on the circumference and forms a slot 11. The slot 11 is bounded by the free side surfaces 44 of the annular projection 42 in the circumferential direction of the cage 10.

The slot 11 is connected to the side opening 43. Specifically, the slot 11 is disposed above the side opening 43 and opens into it. Down the room 13 is through a floor with a lower

Passage opening 14b, in particular circular, lower passage opening 14b limited.

The upper passage opening 14a and the lower passage opening 14b are arranged coaxially. At its lower end, the cage 10 has a bottom 45 with a recess 46 which is open at the side and on which two latching noses 15 are formed. As shown in Fig. 2b, the cage 10 can be pushed with the recess 46 in the head 41 of a screw 40 which is laterally slotted.

Between the screw 40 and the bottom 45 of the cage 10, a positive connection is formed in the assembled state.

The screw 40 is connected to a toilet bowl (not shown), for example a wall attachment member of the toilet bowl. The connection between the fastening system and the toilet bowl can thus be done simply by pushing the cage 10 on the slotted screw 41. The detents 15 hold the cage 10 while on the screw head 41, wherein the cage 10 relative to the screw 40 along the recess

is displaceable. This already provides some flexibility of the

Secured fastening system.

In the assembled state according to FIG. 2 b, the head 41 of the screw 40 is accessible through the two coaxial passage openings 14 a, 14 b, for example, for a hexagon socket wrench.

FIG. 3 a shows the cage nut 20 according to FIG. 1. FIG. 3 b shows a section of the cage nut 20. The cage nut 20 is formed by a molded with plastic 23 nut 22. The cage nut 20 is substantially cylindrical, with a lateral projection 47 with a profile projection 21. Der

Profile projection is on the outer contour or an outer surface of the

Cage nut 20 before. At the upper end of the cage nut 20 is the

Outer contour flat. The profile projection 21 projects beyond the upper end face and forms a nose. The nose extends coaxially with the central axis of the cage nut 20. Others

Orientations of the nose are possible. The central axis corresponds to the axis of rotation of the cage nut 20.

The width of the profile projection 21 is smaller than the width of the slot 11 circumferential direction of the cage 10th The lateral projection 47 projects radially beyond the cylindrical outer surface of the cage nut 20. At the top, d. H. at the outer edge or at the

Outer edge of the cage nut 20 of the profile projection 21 is arranged. On the top of the cage nut 20, a ring-like flange 24 is also formed on the circumference of the Einschraublochs.

In Fig. 4a, the cage 10 can be seen with the cage nut 20 received. The cage nut 20 is through the lateral opening 43 of the cage space thirteenth

inserted. The flange 24 of the cage nut 20 engages in the slot 11 of the cage 10. Thus, the cage nut 20 is rotatably storable, with a game in the circumferential direction is allowed. Acts a moment on the cage nut 20, this hits one of the side surfaces 44 of the slot 11 and is blocked (rotationally fixed storage).

Since the outer diameter of the cage nut 20, specifically the outer diameter of the cylindrical basic shape of the cage nut 20, smaller than that

Inner diameter of the cage 10 is the cage nut 20 in the cage 10th

simultaneously radially displaceable.

The annular flange 24 is loosely engaged with the upper through opening 14a of the cage 10, so that it does not restrict the radial mobility of the cage nut 20, but an additional support for the cage nut 20 in

recorded state.

As the section in Fig. 4b shows, the space 13 of the cage 10 at the

opposite side of the insertion opening 43 is closed. Thus, a stop 12 is provided for the cage nut 20, which ensures that it does not fall out of the space 13 when inserting. As can be seen from FIG. 4b, the screw head 41, onto which the cage 10 is pushed, is accessible through the coaxial through openings 14a, 14b even when the cage nut 20 is inserted, so that the screw 40 can be screwed in after the cage nut 20 has been inserted.

The connecting element of the fastening system to the toilet seat forms the fastening means 30, specifically the threaded bolt (FIG. 5). The

Fastener 30 has at the lower end a thread 31 which in the

Cage nut 20 is screwed. At the upper end of the fastening screw 30 a pin 32 is formed, which serves for connection to the toilet seat. It can be attached to the pin 32, for example, a hinge of a toilet seat. Between thread 31 and pin 32, a stop limit 33 is formed on the fastening screw 30, which extends as a projection around the circumference of the bolt body. The thread 31 does not extend to the projection 33, but it remains a thread-free portion.

The thread 31 is designed as a special thread, for example. With an outer diameter M8.85 and a pitch of 1.25, wherein the cage nut 20 has a matching mating thread. The fastening system is usually in a designated

Deepening of a toilet bowl mounted so that only the pin 32 of the

Fixing screw 30 protrudes from the recess. For aesthetic reasons, it is desirable to cover this depression. This is done in Fig. This is pushed before screwing the fastener 30 from below onto the fastener 30, together with a seal 35, as shown in Fig. 1. The hinge plate 34 is therefore not rigidly connected to the fastening means 30, but merely postponed. It is positioned by screwing in the fastener 30 by the stop limit 33. If a toilet seat on a toilet bowl with the inventive

Attached fastening system, the cage nut 20 is first inserted into the cage 10. Then the cage 10 is connected to the toilet bowl,

For example, by attaching to a slotted screw head 41. It is, as described above, possible to screw the screw 40 after attaching the cage 10 with inserted cage nut 20. For this purpose, the nominal diameter of the internal thread of the cage nut 20 is greater than the key width, for example. A hexagon socket wrench for tightening the screw 40. This is particularly advantageous if the measures provided for the fastening system depressions in the pelvic body are dimensioned so that a plugging of the cage 10 and an insert the cage nut 20 are not possible when the cage 10 is in the recess.

In order to fasten the toilet seat, now the fastener 30 is screwed with a hinged hinge plate in the cage nut 20, but not tightened to the stop. Since the cage nut 20 is displaceable in the cage 10, the fastener 30 can be in the still loosely screwed state now position exactly. Since the hinge plate 34 is only loosely pushed onto the fastening means 30, its position can be adjusted exactly.

By the engagement of the profile projection 21 in the slot 11, the cage nut is rotatably mounted. Thus, the fastener 30 can be tightened after adjusting the position of the pin 32. The stop limit 33 fixed in the tightened state, the position of the hinge plate 34. Since the

Plastic encapsulation 23 of the cage nut has a certain elasticity, "locks" the cage nut 20 when tightening the fastener 30 in the cage 10 and is thereby fixed, so that the pin 32 is no longer displaced when attaching the toilet seat a mounted on the toilet seat hinge on the pin 32 of the fastener 30 and locked with the pin 32nd
