Abstract

The seat has a spraying device for delivering fragrance while using the toilet. A releasing mechanism is arranged between toilet glasses (12) and a toilet cover (11) for releasing the spraying device in a hinge area. The releasing mechanism reacts and releases the spraying device during closing or opening of the toilet cover on the spraying device. The spraying device impinges a releaser during relative motion of the toilet cover and the toilet glasses.

Description

The present invention relates to a toilet seat comprising means for dispensing a fragrance when using the toilet.

The prior art includes numerous writings dealing with the problem of eliminating the nuisance odors that arise when using a toilet. In this case, suction devices are generally used, as for example in the DE 297 14 137 U1 are described.

In the US 2008/0256692 A1 a device of the type mentioned is described in which suction openings are provided in the area of the underside of the toilet lid, further a suction device to suck odoriferous gases in the toilet lid, wherein the sucked air is guided in a cavity in the toilet lid and finally via outlet openings of the lid radially the inside is ejected. The triggering of the suction mechanism via a switch provided with a contact pin, which responds to the weight of a person who sits down on the toilet seat. It can also be provided that the sucked air is sucked through a special filter, which is impregnated with a perfume, in order to enrich the re-emitted air with a perfume in this way. In this known device, at least one fan for the suction function is necessary with an electrical supply. In addition, the parts that make up the toilet seat are complex plastic moldings whose production is costly and which have little in common with a conventional toilet seat.

From the U.S. Patent 5,345,617 A1 Furthermore, a device for the extraction of odorous gases is known in which only the suction and the outlet openings are housed in the toilet seat itself, while the actual extraction is housed externally in a separate housing with fan and filter device, which takes up a considerable amount of space. In addition, here lines are required, leading from the toilet lid to the suction device and an electrical supply for the suction mechanism, the mains power required. This known device thus requires a considerable installation effort as well as most other known devices of this type.

From the US 4,914,757 For example, a control device to be integrated on the back side into a hinge mechanism of a toilet seat is known, which is coupled to the flushing mechanism.

The triggering of the flush causes via a coupling a hydraulically braked lowering of the lid on the toilet seat. Here, if necessary, a disinfecting and / or deodorizing device can be actuated. As a deodorizing device here a commercial room spray with push button valve is provided. A disadvantage of such sprays, which are designed for one-handed use, is that they are to shake before use in order to ensure a homogeneous mixing of propellant gas and perfume aerosol. It is thus firmly integrated into a dispensing device that causes segregation and inadequate, irregular release of aerosol.

From the GB 1,096,114 a spray device for sanitary systems with articulated seat element is known in which the spraying device, comprising an aerosol pressure vessel with control device, is connected via the control device with the hinge mechanism. By pivoting the seat member, a dispensing valve is opened via the control device and sprayed liquid out of the container. Disadvantageous here too is the use of a valve for removing the deodorant from the pressure vessel, which, as already described above, can not ensure a homogeneous, repeatable release of deodorant.

From the GB 3,336,603 a deodorant device for toilet seats of cisterns toilets is known in which a deodorant distributor between toilet seat and cistern is arranged and has a laterally oriented release device. About the triggering device, the delivery of deodorant is effected from a pressure valve via a discharge channel into the toilet inside. The dispenser can be connected in the form of a push button with a lever mechanism. A disadvantage of this device is the cistern and seat additionally arranged lying deodorant distributor. On the underside of the deodorant distributor, the surface of the sanitary ware is inaccessible, as a result of which rapidly polluting, unsightly areas are formed.

From the GB 702,060 an improvement for hinges is known in which at least one hinge is additionally provided as a housing with a blind hole. The blind hole has lateral opening slots, in which engages at least one hinge pin, wherein the blind hole can be closed when inserted hinge pin with a cap. The blind hole holder of the hinge pin is in turn connected via behind-reaching screw with the toilet itself. Furthermore, the blind hole can also be used to hold a deodorant container. The disadvantage of this is that you have to be at least partially unscrewed and separated from complex facilities mounted in each other in order to expose access to the closed by hinge pin blind hole. One The built-in deodorant container is hardly accessible and interchangeable only with much effort.

From the WO 99/17650 is a metering device for perfume agents o. Ä. Known that dispenses from a mounted on or in the lid of a toilet seat storage container with closed lid perfume agent in the interior of the bowl. A disadvantage of this construction is that the weight of the lid is significantly increased by the reservoir attached to or in the lid; As a result, the usual folding down of the lid occurring pulse is additionally increased. The repeated, increased impact load the cover is damaged faster and also the stability of the associated reservoir is impaired.

The object of the present invention is to provide a toilet seat comprising a device for dispensing a fragrance when using the toilet of the aforementioned type, which does not require built-in suction devices such as fans or the like and without external suction and complex installations ,

Furthermore, it is an object of the present invention to overcome the disadvantages of the prior art.

The solution to this problem provides a toilet seat of the aforementioned type with the characterizing features of the main claim.

According to the invention, a spray device integrated into the toilet seat is provided which emits a fragrance when actuated, wherein a mechanism for triggering the spray device in the hinge area between toilet seat and toilet lid is arranged, which acts upon closing or opening the toilet lid on the spray device and triggers this.

The invention thus takes a fundamentally different route than the prior art. Extraction or recirculation is not considered necessary. There is only a release of a fragrance when using the toilet. In principle, manually operated spraying devices for dispensing fragrances in the form of room spray in spray cans are known. However, these must be operated by a person, so that there is no guarantee that such an operation also takes place. In contrast, the present invention shows superior, since in any case the operation of the spray device is forcibly ensured when closing or opening the lid of the toilet seat.

In the present application, the commonly associated via a hinge (joint) unit of toilet seat and toilet lid is referred to as a toilet seat. When using the toilet, the toilet seat remains in its horizontal position while the toilet lid is opened and folded up. In this pivoting movement, the lid rotates generally about a horizontal connecting axis in the hinge area. Preferably during the closing movement after the use of the toilet, the spraying of the fragrance is triggered. This release can also be provided additionally or optionally alternatively when opening the lid. Due to the relative movement of both components toilet lid and toilet seat each other can be acted upon, for example via a built-in mechanism thrust element a trigger of the spray device.

It is advantageous if the toilet seat has a mounted in the hinge area removable holder that receives the spray device. This holder may for example be releasably attached to a bearing part, which is fixedly mounted on the toilet bowl. This bearing part can preferably also serve for the pivotable attachment of toilet lid and toilet seat. The holder can be easily removed, for example via a positive connection with the bearing part, so that you do not need a tool, for example, if you want to replace an empty spray can or if there is a defect on the sprayer. To do this, for example, with a handle, the holder from the toilet seat and opens a lid or a flap of the holder, whereupon then the spray device can be removed.

A preferred variant of the task solution according to the invention further provides that the thrust element cooperates with a pivot, which is rotatably connected to the toilet lid. The rotational movement of such a pivot when pivoting the toilet lid can be implemented via suitable means in an axial movement of the pusher. This pusher is then advanced a bit, for example when closing the toilet lid and thereby acts on a spray head of the sprayer so that it is triggered.

In a particularly preferred constructive embodiment according to the invention, it is provided that the thrust element is guided axially displaceably and non-rotatably in a sleeve, so as to prevent the thrust element being rotated during a rotational movement of the pivot. Such a sleeve can, for example, in a Gelenkanformung the bearing part be kept unrotatable. Particularly preferred is the use of at least two such sleeves each in the region of the articulations of the bearing part.

Particularly advantageous in such a preferred solution is that one used for the pivotal storage of toilet lid and toilet seat on the toilet bowl bearing part on the one hand for the removable attachment of the holder for the spray device and also for the attachment of the articulated storage of the lid and glasses can use necessary axle elements. The toilet seat according to the invention with a spray device for a fragrance visually differs only slightly from a toilet seat conventional design, which promotes its acceptance by the consumer. Changes exist in particular in the joint areas. The construction height is at most slightly larger than in a conventional toilet seat. This is different from the mentioned known solutions with suction device in the toilet seat, which are much bulkier than a conventional toilet seat.

The features mentioned in the dependent claims relate to preferred developments of the task solution according to the invention. Further advantages of the invention will become apparent from the following detailed description.

Hereinafter, the present invention will be described in more detail by way of embodiments with reference to the accompanying drawings.

First, on the FIG. 1 Referenced. The illustration shows a perspective view of a portion of a toilet seat according to the invention, namely the joint area, which is of interest in the present case, looking in the drawing from the bottom of the toilet seat, so that the toilet seat 12 in the representation before the Toilet lid 11 is located. The toilet seat comprises first as a conventional toilet seat, a bearing part 10 which is attached to a toilet bowl and thus represents the fixed part of the joint to which the toilet lid 11 and the toilet seat 12 are each articulated. On the bearing part 10 there is a first Gelenkanformung 13 and at a distance to a second Gelenkanformung 14. At the toilet seat 12 are two hinge eyes 17, 18 so that the toilet seat 12 independently of the toilet lid on the toilet bowl on the bearing part 10 pivotally attached is, these hinge eyes 17, 18 in the mounted state in each case outwardly adjoin the two Gelenkanformungen 13, 14 and adjacent to these. At the toilet lid 11 are also two spaced hinge eyes 15, 16 are mounted for the pivotal attachment to the toilet bowl. The arrangement is in the assembled state so that the two joint eyes 15, 16 of the toilet lid 11 are furthest outward, then each inwardly in the axial direction, the two joint eyes 17 and 18 of the toilet seat 12 follow and then as each furthest inside Hinge elements join the two Gelenkanformungen 13, 14 of the bearing part 10, as well as the two Figures 2 and 5 can take.

For the pivotable mounting of toilet lid 11 and toilet seat 12 on the bearing part 10 various sleeve-like or peg-like components are provided which extend through the Gelenkanformungen and hinge eyes through and are thus aligned substantially in the direction of the pivot axis. On one side of the assembly, the pivot bearing comprises the socket 26, pivot 25, first sleeve 24 and pusher 22. The details of this arrangement will be discussed later with reference to FIGS FIGS. 2 and 4 explained in more detail. On the other side of the arrangement, the pivot bearing comprises the plug-in pin 29, the plug-in axis 28 and the second sleeve 27. The details of this arrangement are apparent from the FIGS. 5 and 6 and will be explained in more detail below.

The sprayer (spray can) 19 is like FIG. 3 shows recorded in a holder 20, from which it can be removed. The holder 20 is in turn removably mounted on the bearing part 10, so that it can be removed, for example, for the purpose of replacing the empty spray device of the toilet seat. The components used for the mounting of the holder 20 will be explained in more detail below.

The spraying device comprises a spray head 21, which is axially movable in the direction of the spray can and which has an in FIG. 2 recognizable thrust element 22 can be acted upon, so that it is pressed and then triggers a spray. The thrust element 22 is guided during its axial movement and is held in the region of the first Gelenkanformung 13 of the bearing part 10 axially displaceable. The movement of the pusher element is triggered by a mechanism which is coupled to a pivotal movement of the toilet lid 11, so that, for example, when closing the toilet lid 11, an axial feed movement of the pusher 22 over a certain distance is triggered, which causes the pusher element 22 on pushes the spray head 21. When closing the toilet lid, the pusher moves back to the starting position.

In FIG. 3 it can be seen that the holder 20 for the spray can 19 has a pivotally mounted cover 23, which can be opened so that you can then remove the spray can 19 from the holder 20.

It will now be with reference to the FIGS. 2 and 4 the mechanism for acting on the pusher 22, its interaction with the pivoting toilet lid 11 and the components used for the pivotal mounting of the toilet lid on the one side of the arrangement explained in more detail. The thrust element 22 is received in the mounted state of a first sleeve 24, which in turn can be inserted up to a stop 24 a in a corresponding receptacle of Gelenkanformung 13 of the bearing part 10. For this purpose, the first sleeve has 24 guide surfaces 24 b, which are formed by flats (see FIG. 4 ) and the interior of the receptacle of Gelenkanformung 13 has a corresponding profile, so that the first sleeve 24 is received positively in the receptacle of Gelenkanformung 13 and held against rotation. With the thrust element 22 of the pivot pin 25 cooperates, which in FIG. 4 can fully recognize while in FIG. 2 only the plug-in extension 25 a sees, which is received by a plug-in receptacle 26 b in the form of a plug-in sleeve 26. This plug-in sleeve 26 in turn has its own outer flattened portions 26 a, so that they can be positively received in a receptacle 15 a in the interior of the joint eye 15 of the toilet lid 11.

The socket 26 is pushed with its shaft through the hole 17 a of the joint eye 17 of the toilet seat 12 through, as shown in FIG. 2 is indicated. Thus, the plug-in sleeve 26 is rotatably connected via a positive connection with the hinge eye 15 of the toilet lid 11, wherein, however, the rotatability of the socket 26 is given in the joint eye 17 of the toilet seat 12.

The plug-in sleeve 26 is rotatably connected via its plug-in receptacle 26 b with the plug-in extension 25 a of the pivot pin 25, so that a rotational movement of the toilet lid 11 is transmitted via the hinge eye 15 and the socket 26 and on the pivot pin 25. This pivot pin 25 is freely rotatable within the first sleeve 24. At its end facing away from the plug-in extension 25 a of the pivot pin 25 has a cylindrical guide pin 25 b, which in a suitable in FIG. 4 unrecognizable bore of the thrust element 22 engages. In addition, 25 bevels 25 c or curved surfaces are formed at this end of the plug-in extension, so that there is an inclined plane, which cooperate with corresponding slopes 22 a on the thrust element 22. In the densest position of pivot 25 and thrust element 22, these elements engage at least partially in one another. As the pivot 25 is rotated, the corresponding ramps or elements of an inclined plane of pivot 25 and pusher 22 slide on each other, displacing the pusher in the axial direction, reducing the engagement of the elements, and increasing the axial spacing of the pivot and pusher ends. The thrust element 22 can not twist, since the outer contour 22 b of the thrust element 22 is selected outside with surfaces so that it engages positively in the corresponding inner contour of the first sleeve 24. Their inner contour results from inner surfaces, which in FIG. 4 correspond to visible outer guide surfaces. Accordingly, if the pivot pin 25 is rotated in the sleeve 24, this leads to an axial displacement of the thrust element 22 due to the bevels 25 c, 22 a such a way that presses in the remote position, the front end of the thrust element on the spray head 21 and thus the Release of the fragrance triggers.

Since the first sleeve 24 is held in the Gelenkanformung 13 of the bearing part 10 and the socket 26 rotates with the hinge eye 15 and the pivot pin 25 in the first sleeve 24, thereby also a pivot bearing for the pivoting toilet lid 11 is provided on the bearing part 10.

Hereinafter, referring to FIGS FIGS. 5 and 6 the storage of Toilettenbrille12 and the toilet lid 11 at the second Gelenkanformung 14 of the bearing part 10 explained. Also the second Gelenkanformung of firmly mounted on the toilet bowl Bearing part 10 receives a sleeve 27. This second sleeve 27 may be designed as well as the first sleeve 24, but is aligned in the mounted position to this mirror image. This second sleeve 27 takes as FIG. 6 shows the cylindrical portion 28 a of a thru-axle 28 rotatably. The other end of the thru axle 28 is not cylindrical but has lateral surfaces by flats 28 b, so that there is an outer profile, which corresponds to the inner profile of a socket 29 b a socket 29 so that the thru axle 28 are rotationally connected to the socket 29 can. This plug-in sleeve 29 corresponds in principle to the plug-in sleeve 26 already described above. However, on this side of the bearing, the bores in the joint parts are designed differently than on the other in FIG FIG. 2 presented page. In the joint eye 18 of the toilet seat 12 is not a round hole but a contour hole 18 a, while in the joint eye 16 of the toilet lid 11 is a round receptacle 16 a (round hole), so that the receptacle 29, which engages through the joint eye 18 and engages with its end to the round receptacle 16 a, in this recording 16 a can rotate freely. However, the receptacle 29 is positively received in the receptacle 18 a in the joint eye 18, since this receptacle 18 a has an inner contour corresponding to the outer contour with the flats 29 a of the receptacle 29. As a result, the plug-in sleeve 29 is rotatably held in the receptacle 18 a and thus the toilet seat 12 is rotatably mounted in the second sleeve 27 via the plug-in sleeve 29 and the plug-in axis 28 connected thereto. The second sleeve 27 is as well as the first sleeve 24 with a stop 27 a and 27 b provided guide surfaces and is positively received in a receptacle of the second Gelenkanformung 14 of the bearing part 10 and thus held against rotation in this Gelenkanformung 14. The toilet seat 12 thus has a pivot bearing on the Gelenkanformung 14 of the bearing part 10, but is characterized in that the plug sleeve 29 ends rotate freely in the receptacle 16 a, pivotally mounted on this side regardless of the pivoting movement of the toilet lid 11.

The fixedly connected to the toilet bowl bearing part 10 thus serves as a pivot bearing for toilet lid 11 and toilet seat 12. The two sleeves 24 and 27 are each received up to their stop 24 a and 27 a in the Gelenkanformungen 13 and 14, but each one Head area survives as you look FIG. 2 respectively. FIG. 5 can recognize. Due to the mirror-image arrangement of the two sleeves 24, 27, these head portions project respectively inwards and face each other. In addition, since these head portions of the two sleeves 24, 27 have outer contour surfaces, one can push the two ends of the holder 20 for the spray device form-fitting on these head portions of the sleeves, wherein formed on the holder 20 corresponding to the contour surfaces of the sleeves Engagement surfaces 20 a are located (see FIG. 3 ). Thus, the bearing part continues to serve also for releasably attaching the holder 20 for the spray device.
