Description

Flush toilet having housing with removable cover

Technical Field

The present invention relates to a lower body flush attachment for a toilet or a complete flush toilet with a cover.

Background

Toilets with lower body flushing devices have been known for a long time and are becoming increasingly popular in europe. Lower body flushing devices are used for cleaning by personnel after using a toilet. There are in principle two different constructive forms, namely one that is an integral "unitary device", i.e. a flush toilet in which the flushing device cannot be easily separated from the toilet body with the toilet bowl; and a lower body flushing attachment which is combined with the toilet body, usually as a retrofit solution, and by this combination becomes a flush toilet. In both cases the actual flushing device is usually mounted in the rear area (on the other side of the toilet bowl opening from the user's point of view), usually (in the case of wall mounting) i.e. between the bowl opening and the wall.

The flushing device is here mounted in a housing which, for example, in combination with a seat ring and a toilet lid, forms a lower body flushing attachment (hereinafter referred to as attachment). The housing may also be part of an integrated flush toilet and in this case be mounted on or above the toilet body on the rear side or enter the toilet body in whole or in part on the rear side of the toilet body, for example. Such a housing is in each case exposed on the upper side, wherein the installed state is always relevant here and in the following for the directional description.

It is known to provide a movable cover plate on this upper side. For example, flush toilets are known whose upper side is formed by a cover which is connected on its rear side (i.e. on the far side from the user's point of view) via a hinge to the housing and can be opened about a rotational axis defined thereby. Thereby making access to the operating element; however, it is also conceivable that the interior of the housing and the flushing device can be accessed further in this form.

Disclosure of Invention

On this basis, the object of the invention is to propose an improvement in respect of the cover plate. In this connection, the term "lower body flushing device" is used below and in particular in the claims, whether integral or with an attachment, on the one hand as a generic term for flush toilets and on the other hand for lower body flushing attachments.

This object is achieved by a lower body flushing device according to the invention, namely, on the one hand, a lower body flushing attachment for mounting on a toilet bowl to form a flushing toilet bowl, the attachment having:

a housing for mounting on the rear region of a toilet,

flushing device in a housing and

a movable cover plate on the upper side of the housing in the mounted position, characterized in that the cover plate can be removed from the housing without tools and is separated from the housing in the removed state;

and on the other hand a corresponding flush toilet, i.e. a complete device or a combination of a toilet and an accessory.

In addition, the invention also relates to a mounting pack for producing such a lower body flushing device and to the use of a cover plate for this purpose.

Furthermore, preferred embodiments are shown in the dependent claims and are set forth below in detail together with the basic idea of the invention.

The basic idea of the invention is to configure the cover plate to be removable, which means that it can be removed without tools. In contrast to the prior art described, the cover plate is thus not only foldable, wherein the cover plate remains firmly connected to the housing and the device, but can also be removed (without tools and, of course, without damage).

In this way, the cover plate can be moved freely and can be cleaned in a significantly simpler manner and, if necessary, in other locations (for example in a sink or in a rinsing machine). This is important because toilets and flushing accessories usually and in principle need to be cleaned, the upper side of the device is particularly clearly visible and the sprayers etc. are particularly prone to soiling due to dust deposits according to experience. The cover plate can also be used as a standing surface, which also has a cleaning requirement.

However, the cover plate can also be very easily replaced, for example if the cover plate becomes unsightly or damaged or if it should be replaced by another cover plate for replacement or for aesthetic replacement as desired. For example, the user can be provided with a choice of different cover plates on the part of the manufacturer, from which a choice can be made depending on the requirements of use (surface properties) or aesthetic desires. It is also conceivable for the user to subsequently restock such a cover.

In particular, the installation kit can contain a lower body flushing device without the plate itself, but with a fastening provided for this purpose, and the customer and user of the installation kit can then, for example, make individualized plates by a mason or carpenter as desired, for example, to match other bathroom installations. The individualized plate can be combined with at least one fastening element of the component and can be mounted by means of the fastening element.

Preferably, the cover plate is only movable in translation, i.e. not in rotation, relative to the housing in the non-removed state. For example, a displacement movement for releasing from a snap or clamping connection in combination with a fixing by means of a positive connection can be involved. Although a combination of the invention with a hinged connection between the cover and the housing is conceivable, for example with a hinge solution which can be separated by the elimination of the snap-in, for example by the hinge being placed snappingly on the other circular hinge and likewise being pulled off from it. However, it is preferable to dispense with the hinge or hinge, since the hinge or hinge is relatively complex in construction and requires a certain structural depth in particular in the vertical direction. In the case of the elimination of these solutions, the invention makes it possible to fasten the cover plate to the housing very flat, so that the device as a whole can remain flat or does not unnecessarily restrict the installation space in the housing.

The cover is preferably fastened to the housing via at least one element, referred to herein as a fastening element, which is fastened to the cover. The fastening element can then be connected to the housing, for example by a form-fitting connection, optionally by means of a clamping or snap-fit connection or also simply by clamping. But also magnetic fixation, i.e. a fixture with a magnet that interacts with another magnet on the housing side, or a combination between a steel or iron part on one side and a magnet on the other side. But incorporates a simple mechanical fixing solution with a low cost and, where structurally appropriate, a small constructional depth in the housing.

The at least one fastening element is preferably glued to the cover plate and is then first produced separately. This provides more flexibility in the case of the production of cover plates of different materials, since the fastening itself need not be taken into account for this. The adhesive can be virtually any conceivable material, for example plastic, glass, aluminum, stainless steel or other materials, stone, ceramics, which are also disclosed independently of the adhesive attachment.

Preferably, at least two fixing elements are provided, for example one to the right and the other to the left (from the user's point of view), see the examples.

Preferably, the connection between the at least one fastening element and the housing is a snap connection, wherein the snap itself establishes a certain form-fit connection (i.e. can be elastically released), but preferably additionally ensures a form-fit connection. The form-fitting connection can be ensured, for example, by placing the cover plate and then moving it in the plane of the cover plate so that the projections on the fastening elements engage under the undercuts on the mating elements of the housing and can then be secured in a snap-in manner. However, to ensure this positive-locking connection, for example, simple clamping means are also conceivable and in principle such positive-locking connections can also be made to exhibit sufficient fixing without additional safeguards.

An advantageous embodiment is a clamping structure of the fastening element, which can be configured, for example, as a spring arm on a lateral cut or as a spring bridge on the opening and which supports the corresponding latching means in the event of a snap-fit. The clamping mechanism can be slightly elastically bent by moving the cover plate relative to the housing, for example, and can be brought into the clamping position by a corresponding pressing.

Furthermore, in the mounted state of the cover on the housing (and if necessary the mounted state of the attachment on the toilet body) at least one fixing element (or a plurality of fixing elements) is/are completely covered upwards. In the vertically downward viewing direction, no fastening means are thus visible on the edge of the cover plate.

In conjunction with this (and independently of this), the visibility of at least one front edge of the cover in the horizontal viewing direction is preferred (this direction relates to the horizontal direction of the urinal opening). In this case, the cover plate is not sunk into the recess or is surrounded by a frame which covers the lateral edge. Preferably, this also applies to at least one lateral edge and/or rear edge. The cover plate is thus clearly visible in its material quality and appearance and can be easily joined. Meanwhile, no special cleaning problem is caused by gaps or grooves surrounding the side edges; but the upper side of the housing is preferably kept as smooth and simple as possible around the lateral edges.

In principle, the cover plate, in addition to the fastening elements, is a simple flat plate, which has planar, parallel upper and lower sides. The cover plate may be rectangular in plan view, optionally with rounded corners. However, other shapes are generally conceivable, for example with rounded edges, in particular with rounded edges on the sides and/or the front, or with a trapezoidal shape. Simple flat plates, in particular plates of rectangular shape, can be produced simply from different materials and, if required, also independently of the manufacturer of the device. The respective fixing can be simply applied as described, for example. However, it is also conceivable to push a simple flat plate itself into the form-fitting connection, for example.

For example, a power switch of the device, a filling opening for a calcium remover or other flavoring or cleaning additives, a housing screw and/or a nameplate can be arranged below the cover plate. Such devices are generally not very attractive and do not require complex shaping, especially for frequent cleaning in the case of direct dust exposure. These devices are also not required every time they are used and therefore it has proven advantageous to fit under the cover plate. The standard application functions of the devices may also be operated independently of each other, for example by remote operation or by the device.

Detailed Description

Fig. 1 shows a flushing attachment for a toilet according to the invention, specifically with a tank-like housing 1 in the right rear region and a toilet lid 2 in the front region, which is fastened to the housing 1 in a hinged manner, the toilet lid 2 covering a usual toilet seat, not shown. The housing 1 has vertical side walls to the side (right front to left rear in fig. 1) and to the rear (right rear in fig. 1). The front wall of the housing 1 (to the left and to the front in fig. 1) is not visible, but is partially visible in fig. 3 and in any case matches the contours of the toilet lid 2 and the toilet seat. The side wall encloses a space in which a flushing device with, in particular, a retractable flushing arm for cleaning the lower body of a user is mounted.

Figure 2 shows a complete flush toilet with the attachment of figure 1 on a generally conventional toilet ceramic body 3. The attachment covers the ceramic body 3 to the greatest possible extent from above; that is, the toilet lid 2 is matched with the ceramic body 3 in vertical projection and covers the ceramic body 3 almost completely rearward. However, since the toilet lid 2 laterally overlaps the housing 1, the housing 1 is therefore slightly laterally retracted, and a small part of the upper side of the ceramic body 3 is correspondingly exposed in the rear lateral region. The remaining upwardly directed upper side of the toilet bowl in fig. 2 is formed by the toilet lid 2 and by a cover plate 4, which cover plate 4 covers the upper side of the housing 1 and adjoins the part of the toilet lid 2 forward and (as far as possible) sideways.

In addition, fig. 2 also shows an integrated complete flushing toilet, for example when the housing 1 extends down into the ceramic body 3 and is integrated therein. The housing is not important for the invention, since the condition of the cover plate 4 is independent of the housing.

Fig. 3 shows the rear of the housing 1 and ceramic body 3 in fig. 2 and shows a portion of the toilet seat 5 forward (to the left in fig. 3) not visible in fig. 1 and 2. The cover plate 4 is removed and shown at the rear of the housing 1, wherein the underside of the cover plate 4 points forward and upward. It can therefore be seen that recesses 6 for fastening elements 7 are formed on the upper side of housing 1 on the left and right under cover plate 4, fastening elements 7 adhering to the underside of cover plate 4 on the left and right. The fastening elements 7 can be inserted into the recesses 6, so that the cover plate 4 is offset slightly rearward in this case with respect to the position shown in fig. 1 and 2. The cover plate 4 can then be moved horizontally forward from this offset position, as a result of which the projections 8 on the fastening elements 7 engage in the recesses 6 with corresponding undercuts. The fixing element 7 can snap into the recess 6 at the end of the horizontal translational movement, but this is not essential.

Furthermore, a circular plug 9 for a decalcifying solvent for discontinuously decalcifying the rinsing device in the housing 1 can be seen in fig. 3. In addition, a power switch 10 is provided on the upper side of the cover plate 4 and below the cover plate 4. The figures herein strictly show a transparent resilient cover that protects the underlying toggle switch from water.

Furthermore, the cover plate 4 in the mounted state is slightly raised relative to the parts of the toilet lid 2 surrounding the cover plate 4, since the upper side of the housing 1 below the cover plate 4 is substantially flush with these parts of the toilet lid 2. The cover plate 4 thereby rests quasi-floating on the housing 1 with a slight shadow gap and the edges of the cover plate 4 are visible from the front and from both sides.

Obviously, the mounted cover plate 4 can only be moved backwards and only translationally and horizontally for disassembly and in other cases is fixed. In the case of snap connections and also in the case of non-snap clamping connections, a certain force consumption is required for the movement. The cover plate has no hinges and the fixing 7 is very flat. The recess 6 therefore also has to have only a small depth and therefore not substantially influence the position ratio in the interior of the housing 1.

The fixing element 7 can be easily glued to a different rectangular plate as the cover plate 4, for example with the aid of a custom template. Accordingly, the attachment in fig. 1 or the flush toilet in fig. 2 is provided with different variants for selecting the cover provided or by the user setting the other cover 4 as a replacement or retrofit. When the accessory or toilet does not have a plate 4, but is provided with a fixture 7, the user may be provided with a cover plate that matches his personalized bathroom construction particularly well, for example by his masquerier or tiling worker.

Fig. 4 shows, in a perspective view from obliquely above, a corner of the housing shown in fig. 3 to the left and back, which has the mentioned recess 6 and the fastening element 7 inserted therein, but the fastening element 7 has not yet been locked by being pushed forward. The cover plate 4 is removed here (from this perspective). For comparison, fig. 5 shows the same situation in the locked state, in which the fixing element 7 has been moved forward. Fig. 6 and 7 show the same situation in top view.

The projections 8 are first visible in the drawing, specifically in fig. 4 and 6 at the bottom left and top right, respectively, and the projections 8 in fig. 5 and 7 engage in corresponding side cutouts (hinderschnitte). Furthermore, a right-front projection 11 is visible, which projection 11 corresponds to a corresponding elevation in the lateral edge of the recess 6, which projection 11 moves in the recess 6. The projections 11 are not intended for locking but are rather anti-rotation parts in order to prevent the fixing element 7 from being unintentionally glued or mounted on the cover plate 4 or in the recess 6 by rotating it through 180 °.

Furthermore, the detent crosspieces 12 and the corresponding detent crosspieces 13 in the side walls of the recess 6 can be seen on the side and approximately halfway between the front end and the rear end of the fixing element 7. It is evident from a comparison of the figures how the detent rails engage after the forward movement or disengage again from each other before the forward movement and when the rearward movement is used for releasing.

These functions are supported in that the detent rails 12 are mounted on bridge parts 14 on both sides of the fastening part, the bridge parts 14 each being defined by a respective more inner opening 15 in the fastening part and these bridge parts 14 being elastically deformable inwardly into the openings 15 on account of the openings 15. The fastening element is particularly clearly shown in the top views in fig. 6 and 7. The particular shape of the opening 15 optimizes its elastic properties.

Finally, a wall-like enclosure 16 on the upper side of the fastening element 7 can be seen in the drawing, so that the enclosure 16 is not visible in fig. 3 and faces the cover plate 4. The boundary 16 defines and limits the face for application of the liquid adhesive by the robotic mechanism. Here, the boundary 16 prevents in advance that a possible metering is slightly too high and that the liquid adhesive flows out in the direction of the elastic bridge 14. It is thus conceivable to fill the inner face completely or partially with a liquid adhesive or to attach it to an already cured adhesive and to provide a cover plate 4, not shown, in fig. 4 to 7.

The figures show that the fastening is configured to be particularly flat and that it is possible to achieve an effective and simple embodiment with an (in addition waterproof) injection-molded part in the upper side of the housing 1 and with two mutually identical fastening elements 7 and the conceivable simple mounting thereof on the cover plate 4.
