Abstract

The invention relates to a WC seat fitting arrangement in which a pin is connected in a fixed manner to damper arrangement and is inserted into a supporting bush on the ceramic side.

Description

WC seating arrangement

The invention relates to a toilet seat assembly according to the preamble of

Patent claim 1.

Such a toilet seat assembly is known for example from the European patent EP 1 199 020 B1 of the applicant.

This solution has become virtually the standard for attaching Softclose toilet seat sets. In particular, the toilet seat and the toilet cover hydraulic dampers are arranged in mounting straps of the toilet seat set, which are each rotatably connected to an adapter. The adapter has a recess into which a ceramic-side pin dips. The connection between the pin and the adapter can be defined via a lock.

This locking can be done for example by a catch. Solutions are also known in which the lock can be released via a push button or the like.

In these known solutions, the pin dives when placing the toilet seat set on the ceramic in the adapter piece and is supported at the bottom of the receptacle or on a support shoulder of the recording, so that the forces occurring during the load of the toilet seat on this support shoulder be transferred to the respective pin and the ceramic.

In such solutions, it is necessary to produce the support depth of the recording with a low tolerance, so that the production engineering effort is significant.

In contrast, the present invention seeks to provide a solution in which a reliable support with low manufacturing and device complexity is possible. This object is achieved by a toilet seat assembly with the features of claim 1. Advantageous developments of the invention are the subject of the dependent claims.

According to the WC-Sitzgarnituranordnung has a pin which dips into a receptacle of a damper assembly or is designed in one piece with this. The damper assembly is added at least in sections in a mounting strap of a seat or a cover of the seat set. Usually, the attachment via two pins, each of these pins is assigned a damper assembly.

According to the invention, the pin is fixedly connected to the damper arrangement and, with its projecting end portion, dips detachably into a support recess of a support bush arranged on the ceramic side. This preferably has an end face portion on which the toilet seat assembly is supported. This support can take place, for example, in that a peripheral region of the damper arrangement is supported on an end face of the support bushing. Alternatively, the support can also be carried out via the pin, which rests on a bottom of the support sleeve. In principle, it is also conceivable to execute the pin so long that it passes through the support bushing and rests directly on the ceramic. The support can thus be done by resting the damper assembly on the support sleeve. Alternatively, the support can be made by resting the pin on a shoulder of the support sleeve or on the ceramic.

The optional end face portion can be formed, for example, on the end face of the bushing facing the damper arrangement or else as an annular shoulder / step on the outer circumference or on the inner circumference of the support bushing.

Such a solution has the advantage over the conventional solutions that the axial length of the support sleeve can be designed independently of the usual diameter of the damper assembly, so that by increasing the support length a extremely reliable support of the toilet seat set is ensured on the ceramic. The firm connection of the pin with the damper assembly any play in this area is eliminated, so that this type of support has better stability than conventional solutions.

Another advantage is that by supporting the damper assembly along its outer circumference at the easily machined end face portion of the support sleeve or via the pin on the ceramic or at a bottom of the support recess, the manufacture is much easier than in the conventional solutions where one Damper assembly side blind hole had to be made relatively precisely to ensure the support.

In one embodiment of the invention, the support sleeve has a releasable latch for the damper assembly side mounted pin.

In one embodiment of the invention, the damper assembly has an adapter to which the pin is attached. This adapter is rotatably connected to a piston or a housing or other functional element of the damper assembly.

The damper arrangement or its envelope is substantially cylindrical, so that it can be inserted into corresponding cylindrical receptacles of the fastening tabs. The term "cylindrical" is understood not a strictly cylindrical geometry but an approximately cylindrical structure, which may well have radial projections or the like.

In one embodiment of the invention, the pin is force, shape or - preferably - cohesively connected to the adapter piece or the damper assembly. As a result, the pin can also be made in one piece with the adapter or the damper assembly. The attachment of the toilet seat assembly is particularly stable when the pin extends into the receptacle by more than 75% of the diameter of the adapter or damper assembly.

The adapter piece can be made in one or more parts. In principle, it is also possible to form the adapter piece in one piece with the actual damper of the damper assembly.

As mentioned above, the pin may also be supported on a bottom of the support recess or on an annular shoulder on the inner peripheral surface of the support recess. In this case, for example, the diameter of the support recess may be reduced by the annular shoulder to a dimension which is smaller than the outer diameter of the pin.

The pin can be made in one piece with the adapter or an element of the damper assembly - while the geometry of the pin is not necessarily limited to a cylindrical shape. In principle, it is preferable to manufacture the pin from a metal part.

In the case where the toilet seat is supported substantially over the pin on the ceramic and / or a support sleeve, it may be advantageous to provide a gap between an end surface of the support sleeve and the outer periphery of the damper assembly / adapter.

Preferred embodiments of the invention are explained in more detail below with reference to schematic drawings. Show it:

Figure 1 is a highly schematic sectional view of part of a toilet seat assembly;

FIG. 2 shows a detail X in FIG. 1;

Figure 3 shows the view of Figure 2 in not yet locked state;

Figure 4 shows a variant of the embodiment shown in Figure 3 with supported at the bottom of a support recess pin and Figure 5 shows a further variant of the embodiment of Figure 3 with a continuous pin.

In Figure 1, a part of a toilet seat assembly 1 with a toilet lid 2 and a toilet seat 4 is shown. The toilet seat assembly 1 is attached via two toilet seat joints 6 to a ceramic 8. In the illustration of Figure 1, only one of the toilet seat joints 6 is shown.

As described in the prior art described at the outset, the toilet seat hinge 6 has a damper arrangement 10 with a fluid-damped rotary damper 12, the housing 14 of which is connected to an adapter 16 in the illustrated embodiment. In kinematic reversal, of course, a rotary piston 18 may be connected to the adapter. In the illustrated embodiment, the housing 14 and the adapter 16 are at least partially arranged in a fastening tab 20 of the toilet seat 4. The right in the illustration of Figure 1 cantilevered rotary piston 18 is rotatably connected to a mounting strap 22 of the toilet cover 2. In the illustrated embodiment, a pin 24 is fixed in the adapter 16, which protrudes approximately in the radial direction from the adapter 16. The damper assembly 10 has an approximately cylindrical basic shape. The pin 24 immersed in the assembled state in a support sleeve 26 which is fixed to the ceramic 8. The entire toilet seat assembly 1 can thus be placed over the two pins 24 on the two support bushes 26, so that it is fixed in position on the ceramic 8.

The other (left) damper assembly 10 not shown in Figure 1 is then rotatably connected in a corresponding manner with the toilet lid 2 with its rotary piston, while no rotationally fixed connection between rotary piston 18 and the left-hand mounting tab of the toilet seat 4 is present. Accordingly, in each case a damper of the two damping arrangements for the damping of the toilet seat 4 and the toilet lid 2 is responsible. Of course, the adapter 16 and the actual rotary damper 12 may also be integrally formed. As mentioned above, the adapter piece can be made in several parts. The adapter piece can also be non-rotatably connected to the rotary piston 18. In principle, other damper constructions can also be used.

According to FIG. 1, the support bushing 26 has a support plate 28 which enables reliable support on the ceramic 8 and is connected to it by gluing or screwing, for example.

The detail X in FIG. 1 is shown enlarged in FIG. It can be seen a part of the adapter 16, in which a receptacle 30 is formed, in which the upper end portion of the pin 24 is inserted in Figure 1. In the illustrated embodiment, the pin 24 and the adapter 16 are cohesively, for example by gluing or the same connected. Of course, a non-positive or positive connection, for example by screwing, screwing or pressing done. The fabric bond is characterized in the illustration of Figure 2 with the short horizontal lines. Also, a one-piece design of pin 24 and adapter 16 / damper is conceivable.

In the illustration according to FIG. 2, the support bushing 26 and the plate 28 which is widened in the radial direction can also be seen. The support bush 26 has a support recess 32 into which the projecting end section of the pin 24 can be inserted with a sliding fit. In the locked state, the outer circumference of the approximately cylindrical adapter 16 with a peripheral portion on an end face 34 of the support sleeve 26 is located. That is, the toilet seat set is supported on the two end surfaces 34 of the two support bushes 26. The pin 24 thus acts only as a centering with which the damper assembly 10 is centered with respect to the respective support bushings 26.

Both pins 24 are locked by suitable locks with the support sleeves 26. In the illustrated embodiment, the locking is relatively easy via a spring ring which is fixed resiliently in the radial direction in the support sleeve 26 and in a corresponding annular groove 38 of the pin 24 (see Figure 3) is immersed when the locking position is reached, in which the adapter 16 rests on the end surfaces 34. In this locking position, an end face 40 of the pin 24 is not located on a bottom 42 of the support recess 32.

For placing the toilet seat assembly 1 on the ceramic 8, the two pins 24 are initially introduced in sections in the corresponding support recesses 32 of the support bushes 26 and then moved in accordance with Figure 3 in the arrow direction down until the adapter 16 in abutment against the annular end face 34 of Support bush 26 passes. In this position, then also the clamping ring 36 snaps into the annular groove 38 of the pin 24, so that a reliable connection between the toilet seat and the ceramic 8 is made.

This connection can be easily solved by overcoming the locking force. Of course, other locking devices, such as push-button or barrel connections can be realized, as they are known from the prior art. However, these are preferably then - as in the prior art - damper side, but formed support bush side. In principle, the pin can also be made in one piece with the adapter. In kinematic reversal, of course, the housing 14 may be rotatably connected to the toilet seat 4 or the toilet lid 2, respectively. The receptacles of the two fastening straps 20, 22 are accordingly designed such that they are either non-rotatably connected to the rotary piston 18 or the housing 12 of the damper assembly 10. This can take place directly or via adapter rings or the like inserted in the fastening tabs 20, 22.

The axial length of the support sleeve 26 and the projecting end portion of the pin 24 is selected so that a sufficient axial and radial support is ensured. In the prior art, this is not so variable possible because there the insertion length of the pin is limited in the adapter by its diameter. According to the connection between pin and adapter by the permanent determination is much more stable, especially since the support length of the support sleeve can be chosen almost arbitrarily. In the embodiment described above, a peripheral portion of the adapter 16 or damper assembly 10 rests on the annular end surface 34 of the support sleeve 26. In the embodiment shown in Figure 4, the pin 24 is designed with a larger axial length than the embodiment of Figures 1 to 3, so that when inserting the end face 40 of the pin 24 on the bottom 42 of the blind hole-like support recess 32 of the support sleeve 26 rests. In this variant, the support of the damper assembly via the pin 24, so that, as shown in Figure 4, a gap 44 between the peripheral surface of the adapter 16 and the damper assembly 10 and the end surface 34 of the support sleeve 26 may remain. This gap 44 can be selected with any gap width. In principle, it is also conceivable that the gap goes to 0, so that in addition a support on the outer circumference of the adapter 16 / the damper assembly 10 takes place on the annular end face 34 of the support sleeve 26. In the latter variant, however, care must be taken that the tolerances are chosen so that a support of the pin 24 is maintained at the bottom 42.

Instead of the continuous bottom 42, the support surface for the end face 40 of the pin 24 may also be formed by an annular shoulder of the support recess 32, is reduced by the clear width (not shown).

Figure 5 shows a further simplified in construction embodiment. In this variant, the support recess 32 extends through the support sleeve 26 and through the plate 28 therethrough. The pin 24 is formed even longer than in the embodiment of Figure 4, so that it rests with its end face 40 directly on the ceramic 8 or a support surface of the ceramic 8. In this case, it is again preferred to provide the gap 44 between the outer circumference of the adapter 16 / the damper arrangement 10 and the end face 34. As already mentioned, the pin 24 may be formed integrally with the adapter 16. According to the invention, however, it is preferred if a metallic pin 24 is inserted by gluing, pressing, screwing, encapsulation or in any other way in the adapter 16 or any other part of the damper assembly 10. Disclosed is a toilet seat assembly in which a pin is fixedly connected to a damper assembly and is inserted into a ceramic side support sleeve.
