Description

The present invention describes a fastening device for a toilet lid and a toilet seat on a toilet ceramic. Such fasteners are needed to releasably attach the toilet lid and toilet seat to a toilet ceramic such as a toilet bowl. Since toilet ceramics are usually replaced less frequently, such as toilet lid and toilet seat, this must be provided a fixture that is as easy as possible to use and is designed detachable, so that you can solve if necessary toilet lid and toilet seat of the toilet ceramics and another Toilet lid and toilet seat can attach.

Since the toilet lid or the toilet seat on the toilet ceramics to open and be closed again, appropriate joints must be attached to the toilet seat or toilet lid in order to pivot them separately. The toilet lid has a lid joint and the toilet seat has a seat joint. In a preferred embodiment of present invention, the axis of rotation of the toilet lid is equal to that of the toilet seat, so that the seat hinge and the cover joint interlock.

So that toilet lid and toilet seat can be pivotally attached to the toilet ceramics, a connecting element between the seat hinge and cover joint and the ceramic is necessary. This connecting element then connects toilet lid and toilet seat with the ceramic in such a way that by means of the joints, namely cover joint and toilet lid, they can be pivoted on the toilet ceramics.

Such a fastening device is for example in the WO 2012/019 527 shown. In this case, two brackets are attached to the ceramic, each having a mandrel. On this mandrel then a sleeve is placed, in which damping elements are introduced, which engage in the joints of toilet lid and toilet seat. By attaching the sleeve to the mandrel and a corresponding locking device toilet seat and toilet lid are removably mounted to the toilet ceramics.

A disadvantage of this type of attachment, however, is that during assembly or disassembly a hand is needed to operate an unlocking and thus the placement or release of the toilet lid of the toilet ceramic is designed according to difficult. Another disadvantage of the fastening device of the prior art is that frequent use and tolerances in the production of the connection on the mandrel receives a certain amount of play and thus the attachment is unstable.

Object of the present invention is therefore to realize a fastening device for a toilet lid and a toilet seat to a toilet ceramic, which overcomes the disadvantages mentioned above. This is done by a mat which protrudes at least partially into the mandrel receptacle. Likewise, the mat forms the bottom of the holder, which rests on the toilet ceramics, as well as areas on the circumference of the holder.

On the one hand, this mat is elastic in that it can adapt its contour, on the other hand it has a high frictional force, which is higher than that of the material from which the holder is made, for example to hold the mandrel in position.

An inventive device for a toilet lid and a toilet seat is thus equipped with a seat hinge and a cover joint on the mounting side of the toilet lid and the toilet seat. This means that the seat hinge is positioned on the same side as the lid hinge when mounted on the toilet bowl. According to the invention, the seat hinge and the cover joint are designed as a bore with corresponding guides. These guides can represent lateral supports, so that the bore then has a nearly rectangular base or as a guide struts or guide, so that a corresponding counterpart can be inserted into the hole.

The counterpart according to the invention is a damping unit, wherein this damping unit consists of at least one damping and with at least one axis of rotation, which engages in the mounted state in the above-mentioned joints. Thus, the axes of rotation described here must have the same footprint as the seat joints or cover joints. When mounting then the axis of rotation protrudes into the seat hinge or in the cover joint. The damping is in turn completely inserted into a sleeve, so that only the axis of rotation still emerges at the longitudinal ends of the sleeve. In a preferred embodiment, two dampenings are introduced into the sleeve, each at each longitudinal end of the sleeve. Thus, in each case protrudes on both sides of the sleeve in each case an axis of rotation of the damping.

When mounting the rotary axes are now introduced into the corresponding joints, the rotation axes are rotatably mounted in the joints and rotatably mounted in the damping in the sleeve. The axis of rotation can now be rotated with respect to the damping, but with a corresponding damping of the rotational movement. Thus, in the mounted state, the sleeve can be rotated with the dampers against the toilet lid or the toilet seat.

On the sleeve itself at least one mandrel is attached, which projects radially from the sleeve. At the toilet ceramic each holder is provided per spike, which is fastened by means of a longitudinal hole in the holder on the toilet ceramics. This can be done for example by simple screwing. The holder itself has in each case a mandrel receptacle, in which the mandrel of the sleeve can be introduced.

Part of the holder now forms the above-mentioned mat according to the invention. This protrudes at least partially into the mandrel receptacle and at the same time forms the bottom of the holder, by means of which the holder rests on the toilet ceramic in the assembled state.

Upon insertion of the mandrels into the mandrel receptacles, the mandrel now interacts with the portion of the mat which projects into the mandrel receptacle. Furthermore, the mandrel receptacle on the inner wall has mat guides, which represent, for example, grooves. Due to the above-mentioned high frictional force and the elasticity of the mat, the mandrel is now held in its position in the mandrel holder and thus in the holder. The mandrel is thus releasably held by the frictional force of the mat, which acts on the mat guide on the inside of the mandrel. To solve this mount, it is then sufficient to overcome the frictional force of the mat on the mandrel, thus extracting the mandrel holder out again.

The elasticity of the mat ensures that during long-term operation or frequent assembly or disassembly a corresponding clearance between mandrel and holder is avoided and thus the connection remains stable. Also, a simple assembly and disassembly is possible because in addition to the force required by the lifting of the mandrel from the holder no further hand is needed, as with an additional locking.

The fact that the mat also forms the bottom of the holder, with which rest the brackets on the toilet ceramics, no play can arise here by the frictional force or the holder does not slip on the toilet ceramics. The mat is made of a material which has a higher frictional force. This can be for example rubber. However, using a longitudinal hole to attach the bracket to the toilet bowl ensures that the position of the bracket can be adjusted.

In a preferred embodiment, each holder has at its outer radius mat guides, which are for example also designed as grooves. The mat itself then has the same footprint as the bracket and forms the bottom of the bracket. Mat webs made of the same material as the mat and thus belonging to the mat are applied to the mat. According to the mat guides inside or mat guides outside the mat has matching mat webs inside and mat webs outside. When introducing the mat in the holder then penetrate the mat webs inside in the mat guides inside and the mat webs outside in the mat guides outside. Likewise, in a preferred embodiment, the mat has a longitudinal hole wall which projects at least partially into the longitudinal hole of the holder. By this construction, the mat forms the bottom of the brackets, but also forms parts of the outer wall of the holder, the inner wall of the mandrel holder, as well as parts of the longitudinal hole.

As already described, the bottom of the bracket acts by the fact that it consists of the mat, by its friction force slip-resistant on the toilet ceramic. The parts of the mat, which protrude into the mandrel receptacle, acting by their frictional force on the mandrel and the parts of the mat, which protrude into the longitudinal hole, thus providing additional support of the holding force of the fastener with which the brackets are held in the ceramic. This can be screwed, but also appropriate locking means.

For a better look a cover for each bracket is provided, which also has the same base, such as bracket and mat and which is simply placed on the bracket.

The cover then holds on the holder by the frictional force of the parts of the mat which protrude on the outer wall of the holder. The cover has an opening in the same shape and in almost the same dimensions of the mandrel receptacle so as not to cover it, so that further the function of the holder is ensured.

In order to simplify the introduction of the mat in the holder, positioning pins can be provided in a preferred embodiment, which engage in recesses provided in the holder. This ensures optimal positioning of the mat in the holder.

In a further embodiment, in addition to the holding force, which is realized by the frictional force of the mat on the mandrel, a locking means may be provided which can be introduced into a latching guide of the brackets. Such a latching guide has a radially outwardly running recess in the holder, in which the latching means can be introduced and which exerts an additional holding force on the mandrel in the mounted state. For example, the locking means may consist of a detent which is pressed by a detent spring in the direction of mandrel receptacle within the detent guide. The detent spring, in turn, is supported on a detent cover, which holds the detent nose and detent spring inside the detent guide and closes the detent guide to the outside. The mandrel may have a groove in this embodiment, in which then the locking lug can engage spring loaded. By the spring-loaded holding force of the locking lug in the groove of the mandrel an additional holding force is exerted on the mandrel to hold it in the mounted state in the holder, in addition to the holding force by the frictional force of the parts of the mat protrude into the mandrel holder.

In order to facilitate the assembly of the sleeve with the axes of rotation in the joints, in a further preferred embodiment a spring is provided which extends longitudinally within the sleeve and acts on the dampers so that both of them outwardly in the direction of the joints be pressed. In this case, only the damping by overcoming the spring force must be pushed further into the sleeve during assembly, until they then intervene by the spring force with their axes of rotation in the joints.

Thus, the damping can be performed in the sleeve rotationally fixed, fitting means may be provided in the sleeve, by which the dampers are held in position. This can be corresponding locking devices or simple guide grooves or webs, in which the attenuations can be adjusted.

In Fig. 1 the toilet lid 11 and the toilet seat 12 is shown as a unit, as both parts interlock. The cover hinge 14 and the seat hinge 13 here have the same axis of rotation, so are arranged on the same axis of rotation. Toilet lid 11 and toilet seat 12 are thus rotated about the same axis in order to pivot both separately on the toilet ceramic can.

The dampers 23, in this case two pieces, have a rotational axis 26 projecting from the damping 23 and are both accommodated in a sleeve 20. The introduction of the damping 23 in the sleeve 20 is such that the damping 23 is completely absorbed in the sleeve 20, only the axis of rotation 26 still protrude on the sides of the damping 23 and in the mounted state of the lateral openings of the sleeve 20. The axes of rotation 26 are introduced during assembly in the seat hinge 13 and the cover joint 14. For this purpose, the axes of rotation 26 have different base areas or profiles, which are correspondingly rotatably inserted in the seat hinge 13 and cover joint 14.

The axes of rotation 26 are rotatably connected to the damping 23, wherein a damping takes place for the rotational movement. The dampers 23 are mounted in the sleeve 20 so that they are rotatably mounted in the sleeve 20. The fact that now in the mounted state, the rotational axes 26 rotatably in the seat hinge 13 and cover joint 14 are introduced and the damping 23 rotatably in the sleeve 20, the sleeve 20 is rotatable relative to toilet lid 11 and toilet seat 12 in the assembled state a sleeve spring 24 mounted between the two dampers 23 to press them in the assembled state respectively in the direction of the seat hinge 13 and the cover joint 14. This facilitates assembly, since during assembly, the two dampers 23 are simply compressed to introduce them into the seat hinge 13 and cover joint 14. The spring force then locks them in automatically.

In this Fig. 1 two mandrels 21 are mounted in the sleeve 20, which project in the radial direction of the sleeve 20. Each of these mandrels 21 has a groove 22. According to the number of mandrels, in this case two, brackets 31 are provided, in which the mandrels 21 are introduced. The brackets 31 are attached by appropriate means to the toilet ceramic. This can be done via designated mounting means 50 in the ceramic, via which then the brackets are attached to the toilet ceramic, for example, by screwing or latching. Such mounting means may be, for example, dowels.

Likewise, additional locking means, which are assigned in the holder 31, are provided, namely a detent 33, a detent spring 34 and a Detent cover 35. This locking means is introduced in the above-mentioned order in the holder 31. This additional detent is described in more detail in the following figures. The aim of the detent is to exert an additional holding force on the mandrel in the mounted state.

Likewise, the holder 31 is associated with a cover 30 here.

In Fig. 2 It can now be seen in more detail how the attachment of the toilet lid 11 and the toilet seat 12 via the sleeve 20 in the brackets 31, which are mounted on the toilet ceramics happens. The holder 31 itself is fastened here via a longitudinal hole 36 on the ceramic via, for example, a screw connection.

The holder 31 consists partly of a mat 40, which forms the bottom of the holder 31, but this mat 40 can also be seen at other locations of the holder 31. Thus, the mat has 40 mat webs outside 41 and mat webs inside 42, the outside in corresponding mat guides 38 and 39 mat guides are introduced. As a result, the mat 40 protrudes in regions into the mandrel receptacle 37, and partially into the circumference of the holder 31. Likewise, the mat extends at least partially into the longitudinal hole 36 in.

The mandrel receptacle 37 is now partially on the inner wall of the mat 40 and the material of the holder 31. Preferably, the holder 31 is made of plastic.

The mat 40 is made of a material which is elastic with respect to the material of the holder 31 and is provided with a higher frictional force, for example rubber. If now the mandrel 21 is inserted into the mandrel receptacle 37, the mat web inside 42 is slightly deformed and held by the frictional force of the mandrel 21 in the interior of the mandrel receptacle 37. For this purpose, the mat webs project inside 42 a little further into the mandrel receptacle 37 as the inner wall of the mandrel receptacle 37th

In order to increase the support of the mandrels 21 in the brackets 31, in addition to each holder 31, a locking means may be provided, consisting of detent 33, detent 34 and detent 35. These are inserted in the order given in a detent guide 32 in the bracket 31. In these locking guides 32 is a recess in the holder, which leads from the scope of the holder for mandrel holder 37. The cover in the form of the latch cover 35 ensures a point of application of the spring 34, as well as a nicer closed optics of the holder 31. The spring 34 can thus be supported on the latch cover 35 and press the latch 33 in the direction of mandrel holder 37.

When introducing the mandrels 21 into the mandrel receptacle 37, the detent 33 is then pushed away a little from the mandrel receptacle 37 and the spring 34 is compressed until the detent 33 engages in the grooves 22 on the mandrel 21. By this latching an additional holding force is exerted on the mandrels 21.

To solve toilet lid 11 and toilet seat 12 again from the toilet ceramics, now simply the force must be overcome, with which the mandrels 21 are held in the mandrel receptacles 37 to pull out the mandrels 21. The force with which the mandrel 21 is held in the mandrel receptacle 37, in this case consists of the frictional force of the mat webs inside 42 in the mandrel receptacle 37, and if necessary. From the spring force of the detent spring 34, with the locking lug 33 in the groove 22 of the mandrels 21 intervenes. Thus, only force overcoming is required to solve the fastening device again.

In Fig. 3 is again the structure of the mat 40 to recognize and how this is introduced during assembly of the holder 31 in the holder 31. Also visible on the outer radius of the mat mat webs outside 41 and correspondingly mat guides outside 38 on the circumference of the bracket 31. Also visible are mat webs inside 42, the inside of the designated mat guides inside 39 of the mandrel holder 37 are introduced. Thus, parts of the mat 40 on the circumference 31 of the holder are present, and on the inner wall of the mandrel holder 37th

The mat 40 further has a longitudinal hole wall 43, which thus represents parts of the longitudinal run 36 in the mounted state. In addition, positioning pins 44 are also provided, which can also engage in corresponding recesses of the holder 31 for positioning of the mat in the holder.

While the mat webs are used internally 42 to hold the mandrel 21 in the mandrel receptacle 37, the mat webs outside 41 are intended to the in Fig. 1 to keep seeing cover 30 on the bracket 31, also by friction. After application of the cover 30 on the holder 31 then only the mandrel holder 37 is accessible. All other elements of the bracket 31 are covered to beautify the optics.

The present application is not limited to the features of the description. Rather, further embodiments are conceivable. For example, the groove 22 could not be circumferentially around the mandrel, but only partially in the direction of the latching guide. Likewise, an adjustment of the spring force, which acts on the latching lug 33 by the spring 34 may be provided, for example, by pass rings are introduced into the latching guide to further compress the spring.
