Abstract

The invention relates to a removable mounting device (1, 1') for a toilet lid, comprising a quick-fit mounting mechanism for the reversible fixing to a toilet bowl, with a damper (8, 8') to exert a force during the pivoting of the toilet lid. The fixing device thus comprises a base element (2, 2'), for fixing to the toilet bowl, a stator element (3, 3') which may be fixed to the base element by means of a quick-fit mounting, a rotor element (6, 6') with a rotating connection to the stator element, comprising an arm (5', 7) for fixing to the toilet lid (51, 52) and a damper (8, 8'), connected to the stator element (3, 3') and the rotor element (6, 6') and which exerts a force affecting the rotational movement. The force exerted by the damper (8, 8') can be composed of both elastic components (spring forces) and viscous components (frictional forces). The damper can particularly be applied to exerting a force on the toilet bowl counteracting the lowering of the toilet lid. The above prevents the unbraked accidental falling of the toilet lid onto the toilet bowl.

Description

FASTENING DEVICE FOR LOWERING A TOILET COVER WITH QUICK FASTENING

The invention relates to a removable fastening device for a lowerable toilet cover, comprising a quick fastening mechanism for reversible fastening to a toilet bowl.

A toilet generally consists of a toilet bowl and cover elements for opening the toilet bowl. The cover elements are pivotally connected to the toilet bowl about a horizontal pivot axis in order to be able to be folded into a position releasing the toilet bowl. One of the cover elements is generally formed by toilet seat glasses which, when closed, run over the edge of the toilet bowl in order to enable a more comfortable and comfortable seat on the toilet. Furthermore, the cover elements generally include a toilet lid, which closes the opening of the toilet bowl when it is not in use.

The toilet bowl and the above-mentioned cover elements must be pivotally connected to one another using a suitable fastening device. For the attachment of such a fastening device to the toilet bowl, which is generally made of ceramic, two vertical through holes are provided in the rear area of the toilet bowl. In known fastening devices, a base element is attached to each of the two through bores, which element initially moves upwards pointing and then kinking at right angles into the horizontal, with the help of which a hinge connection to the toilet cover is made. Furthermore, a fastening device is known in which a quick fastening is provided between a base element fixedly mounted on the toilet bowl and a stator element. This has the advantage that the toilet cover together with the stator element can be easily removed from the toilet, so that the toilet and the toilet cover can be cleaned thoroughly.

Against this background, the object of the present invention was to provide a fastening device for a toilet cover which is improved in terms of operating convenience.

This object is achieved by a fastening device with the features of claim 1, by a fastening device with the features of claim 8, and by a system of at least two fastening devices with the features of claim 11. Advantageous refinements are contained in the subclaims.

According to the first embodiment of the invention, the fastening device for a toilet cover has a quick fastening mechanism for reversible attachment to a toilet bowl and a damper for exerting force on the toilet cover during its pivoting movement. The combination of a quick fastening with a damper can significantly increase the comfort of the fastening device both in its maintenance and assembly as well as in its operation. The quick fastening mechanism can in particular have a base element to be fastened to the toilet bowl, a stator element which can be fastened to the base element by means of a quick fastening and a rotor element which is rotatably connected to the stator element, the rotor element having an arm to which the toilet cover (or a component thereof) is fastened can be. The damper is coupled to the stator element and the rotor element and exerts a force influencing the rotary movement.

By interposing the damper between the rotor element and the stator element, a force can be exerted during a pivoting movement of the toilet cover, which supports handling. The force exerted by the damper can have both elastic components (spring forces) and viscous components (frictional forces). The damper can in particular be used to exert a force which counteracts the lowering of the toilet cover on the toilet bowl. This prevents a toilet cover from accidentally falling onto the toilet bowl without being braked. If the damper also has elastic force components, these can have a supporting effect when the toilet cover is installed by compensating for part of the weight.

The rotor element and / or the stator element preferably has a receptacle in which one of two ends of the damper which can be rotated relative to one another can be mounted in a manner preventing rotation. The damper can then be mounted on the stator element on the one hand and on the rotor element on the other hand so that it cannot rotate, so that there is a relative rotational movement between the rotor element and the stator element transmits via the damper, which exerts the desired reaction forces.

According to a further embodiment of the fastening device, the rotor element and the stator element have two sleeve-shaped axle sections which can be plugged into one another and which together enclose a cavity in which the damper is arranged. In this embodiment, the damper is protected with a minimal space requirement and visually concealed, and it can exert its effect directly on the rotor element and the stator element.

Furthermore, in the last-mentioned embodiment, a spring acting on the damper in the axial direction (that is, in the direction of the pivot axis between the rotor element and the stator element) can be arranged in the cavity. This spring ensures that the damper is biased into a predetermined position. In particular, the damper is advantageously automatically pressed into the correct storage position by the spring during assembly of the device, during which there is no longer any access to the damper located in the cavity.

In the case of the sleeve-shaped configuration of the axis sections of the rotor element and stator element, at least one guide projection can also be formed on the rotor element or preferably on the stator element, which engages in a guide groove formed on the other component (preferably the rotor element) and in this way ensures that the rotor element and After assembly, the stator element can be fixed against axial movement and only the pivoting movement in the direction of the guide groove is permitted. Furthermore, the rotor element and the stator element are preferably connected to one another in a bayonet-like manner, for example by the above-mentioned guide projection being able to be introduced into the guide groove via corresponding axially extending grooves. Such a bayonet connection between the rotor element and the stator element can be produced particularly easily and at the same time safely.

According to a development of the fastening device, it has a freewheel element which is rotatably connected to the stator element and which has an arm to which the toilet cover (or a component thereof) can be fastened. The freewheel element can be ring-shaped and arranged around the axis of the base element. In contrast to the rotor element, it is typically not connected to the damper, but can be freely rotated.

According to a second aspect, the invention relates to a fastening device for a toilet cover with a base element to be fastened to the toilet bowl and a stator element which can be fastened to the base element by means of a quick fastening. The fastening device can also optionally be designed in the manner explained above, that is to say in particular be provided with a damper. It is characterized in that the stator element has a blind bore into which a sleeve can be inserted in such a way that a plug-in opening is formed, the diameter of which corresponds to the inside diameter of the sleeve and which has a radial extension. Furthermore, on the base element there is a plug pin which is dimensioned appropriately for the plug opening and which has a spring element which engages in the aforementioned radial expansion of the plug opening when the plug pin is inserted into the plug opening. The described configuration of the fastening device achieves a quick connection between the base element and the stator element, in which the stator element is plugged onto the plug pin and engages there when the predetermined position is reached. In order to release the connection again, a correspondingly greater force must be exerted, which causes the spring element to disengage from the radial expansion of the plug-in opening. An advantage of the quick connection is that the combination of a blind hole with a sleeve inserted therein can be used to produce a plug-in opening with a radial grid extension without the stator element having to be drilled from two sides. This enables a very compact and visually pleasing design of the fastening device.

There are various options for forming the radial extension in the plug opening. For example, it would be conceivable to design the radial extension on the inner wall of the sleeve used as a recess, such as a groove. However, the stator element preferably has a pilot hole which, compared to the blind hole mentioned above, is coaxial, longer in the axial direction and narrower in the radial direction. The blind bore can preferably have an internal thread into which the sleeve can be screwed with a corresponding external thread. Furthermore, the inner diameter of the sleeve, which corresponds to the diameter of the plug-in opening to be produced, is smaller than the diameter of the pilot hole, so that the desired radial widening, into which the spring element of the plug-in bolt can snap, occurs after the sleeve inserted into the blind hole. The invention further relates to a system comprising a first and a second fastening device, each with a damper between a stator element and a rotor element and with a freewheel element which is (freely) rotatably coupled to the stator element. The two fastening devices can in particular be designed in one of the ways explained above. Furthermore, they are designed such that toilet seat glasses can be fastened to the rotor element of the first fastening device and to the freewheel element of the second fastening device, and that a toilet lid can be fastened to the freewheel element of the first fastening device and to the rotor element of the second fastening device.

Both the toilet lid and the toilet seat glasses are thus each attached to a rotor element on which the force of a damper acts. Both components of the toilet cover are therefore subject to the (braking) effect of a damper, the associated damper being accommodated in a space-saving manner on the one hand in the first and on the other hand in the second fastening device. Thus, the lowering of a two-part toilet cover can be braked for each component, although only fastening devices are used, each of which only allows braking of a coupled pivot element.

The invention is explained in more detail below using the figures as an example. Show it:

6 shows a cross section through the assembled quick fastening according to FIG. 5.

FIG. 1 shows an exemplary fastening device 1 according to the invention for a toilet cover with a cover. lowering delay and a quick attachment. The fastening device 1 essentially consists of:

a base plate 2 which is firmly connected to a toilet bowl (not shown);

a stator element 3 which is connected to the base element 2 by means of a quick fastening shown in more detail in FIGS. 5 and 6;

a rotor element 6 which is rotatably connected to the stator element 3 and has an arm 7 to which a toilet seat frame 52 is screwed;

- A freewheel element 4 which is rotatably connected to the stator element 3 and has an arm 5 to which a toilet lid 51 is attached.

The freewheel element 4 gets its name from the fact that - apart from the usual and unavoidable frictional forces - it is freely pivotably mounted on the stator element 3. In contrast to this, the rotor element 6 is coupled to the stator element 3 via a damper 8 (FIGS. 2, 3), the damper 8 exerting an elastic and / or viscous force on the relative rotation between the rotor element 6 and the stator element 3. In this way, in particular an undesired falling of the toilet seat glasses 52 connected to the rotor element 6 from an erected position can be prevented or braked.

In the right part of FIG. 2, the structure of the assembled fastening device 1 is shown once again in a front view (above) and in a top view of a cross section (below). The middle representations show the oval base element 2 in a front view of a longitudinal section and in a plan view. It can be seen in particular that the base element 2 has a grid of nine bores on the underside in order to be able to be adapted to different dimensions of the fastening arrangements on toilet bowls.

It can be seen from the lower sectional view through the fastening device 1 that the stator element 3 and the rotor element 6 have sleeve-shaped axis sections which are directed towards one another and are inserted into one another. The sleeve-shaped axle sections together form a cavity in which an essentially cylindrically shaped damper 8 is arranged. One end of the damper 8 is supported on the rotor element 6 via a compression spring 9, so that the damper 8 is biased axially in the direction of the stator element 3.

Figure 2 contains in the left part a corresponding representation of a second fastening device 1 ', which is arranged opposite the first fastening device 1 on a toilet. The fastening device 1 'is essentially mirror-symmetrical to the fastening device 1 with respect to the central plane of the toilet, corresponding elements being identified by the same reference numerals provided with a dash.

There is an important difference between the fastening devices 1, 1 ': while in the first fastening device 1 the arm 5 of the freewheel element 4 is fastened to the toilet lid 51 (FIG. 1) and the arm 7 of the rotor element 6 to the toilet seat frame 52, this is the case with the second fastening device 1 'vice versa. Here is the arm 7 'of the freewheel element 4' on the toilet seat glasses 52 and the arm 5 'of the rotor element 6' attached to the toilet lid 51 (Figure 1). In other words, the toilet lid 51 is fastened to the freewheel element 4 on the right side and to the rotor element 6 'on the left side, while the toilet seat glasses 52 are fastened to the rotor element 6 on the right side and to the freewheel element 4' on the left side. The braking force generated by the damper 8 or 8 'can thus act on the toilet lid 51 as well as on the toilet seat glasses 52 at least on one side.

Figures 3 and 4 show again in more detail and in different views the components of the fastening device 1 and 1 'according to the invention. It can be seen from the comparison of the figures that the arm 5 or 5 'provided for fastening the toilet lid 51 is molded on the one hand on the freewheel element 4 (fastening device 1) and on the other hand on the rotor element 6' (fastening device 1 '). Similarly, the arm 7 or 7 ′ provided for fastening the toilet seat glasses 52 is formed on the rotor element 6 in the case of fastening device 1 and on the freewheel element 4 ′ in the case of fastening device 1 ′.

Furthermore, it can be seen from FIG. 3 (and analogously from FIG. 4) that the rotor element 6 is sleeve-shaped coaxially to the pivot axis, a rectangular receptacle 10 being formed on the bottom of the sleeve. A complementarily shaped, non-circular plug-in head 12 of the damper 8 can be inserted into the latter in order to be mounted in a rotationally secure manner therein. The opposite non-circular plug-in foot 13 of the damper 8 is correspondingly mounted in a rectangular receptacle 15 on the bottom of the sleeve-shaped stator element 3. Plug head 12 and plug foot 13 of the damper 8 are thus each Weil non-rotatably connected to the rotor element 6 or stator element 3, so that the damper 8 is rotated in itself during a relative rotation between these elements. In terms of construction, it counteracts such a rotation with an elastic and / or viscous counter-torque, which brings about the desired braking of a lowering movement of the toilet cover. Suitable dampers are known from the prior art (for example model TD 14 series from TOK, Tokyo, Japan). During assembly and in the assembled state, a compression spring 9 (FIG. 2) arranged in the receptacle 10 of the rotor element 6 ensures that the damper 8 is pressed into the opposite receptacle 15 of the stator element 3.

It can also be seen that the sleeve-shaped axis section of the stator element 3 has two diametrically opposite projections 14 which project radially outwards. When the stator element 3 is plugged together with the rotor element 6, these can be inserted into a circumferential groove 11 formed on the inner wall of the sleeve-shaped section of the rotor element 6 via corresponding recesses. In the event of a relative rotation between the rotor element 6 and the stator element 3, the engagement of the projections 14 in the groove 11 then ensures that the elements mentioned are fixed with respect to an axial displacement.

The essentially annular freewheel element 4 with the integrally formed arm 5 is rotatably mounted on a cylindrical outer surface of the stator element 3. It is not influenced by the braking effect of the damper 8.

The structure of the quick fastening is shown in more detail in FIGS. 5 and 6. In the fastening device 1, the quick fastening acts between the stator element 3 and the base element 2 fixed to the toilet bowl (not shown) (or analogously between the stator element 3 'and the base element 2' in the fastening device 1 '). For quick fastening, a socket pin 21 is screwed onto the base element 2, projecting vertically upward. The plug pin 21 has at its upper end a circumferential groove 20 into which a spring ring 19 is inserted, so that it projects radially beyond the diameter of the plug pin 21.

The stator element 3 has at its lower end a first “pre-bore” 16 and a second coaxial blind bore 17 with a larger diameter than the pre-bore 16 but with a smaller depth. Furthermore, a thread is formed at the edge of the blind bore 17. A sleeve 18 with a corresponding external thread can be screwed into this thread. The inner diameter of the sleeve 18 corresponds to the outer diameter of the plug pin 21, so that it can be inserted into the sleeve 18. Since, furthermore, the inside diameter of the sleeve 18 is chosen to be somewhat smaller than the diameter of the pilot hole 16, a radial enlargement is created above the front end of the sleeve 18 in the screwing direction, corresponding to an annular circumferential groove into which the spring ring 19 of the plug pin 21 engages can. In this way, a snap-in connection is achieved between the stator element 3 and the base plate 2. It is essential here that the radial enlargement does not have to have holes of different diameters in the stator element 3 from two sides, which would not be possible in the present case due to the densely packed spatial construction or would be possible only with great difficulty and also to one on the top visible opening.
