Abstract

The shock absorbing system for toilet seats and lids comprises a shock absorber (2) whose ends can rotate with respect to each other. This is mounted in a housing (13) which is fastened to the seat or lid. An end piece (11) attached to this, and which can rotate with respect to it, is fastened to the toilet bowl. An independent claim is included for a toilet seat and lid combination fitted with the shock absorbing system.

Description

The invention relates to a device for damping a toilet seat or a toilet lid.

Such devices have been known for some time. They prevent a toilet seat or lid from clanging loudly when closing. In many constructions, only a brief initiation of the closing operation is required, and the toilet seat or lid then slowly lowers the rest of the way until it gently touches down.

The prior art offers a variety of damping devices. The DE 34 37 138 C2 discloses a damping device that is integrated directly into the rear end of a toilet seat and a toilet lid. The damping device is designed as a rotary damper and works with wings that displace a viscous fluid. The flow resistance causes a damping of the pivoting movement of the toilet seat or cover.

Today, rotary dampers are already available in very small sizes. The diameter of commercially available dampers can be for example only 1 cm. Nevertheless, they offer sufficient cushioning and stability. The dampers are in the sanitary technology used in the production of toilet seat cover combinations as purchased parts.

The toilet seat and cover combination according to the DE 100 51 805 A1 uses such a separate damper. The toilet seat has at its rear end to an integrally formed receptacle in which the damper is completely absorbed. On one side it protrudes into another receptacle of the toilet lid; on its other side, an adapter piece connects, which in turn protrudes from the receptacle and is in communication with a toilet bowl associated mounting pin.

The known arrangement is very compact. The toilet seat and the toilet lid are mounted directly on the damper and the adapter. However, the damper and in particular the pivot of the damper are heavily loaded, especially when an actuation of the toilet lid, since the toilet lid is supported solely by the pin. This can lead to damage to the damper, to the escape of the damping fluid or even to a break of the pin and thus complete destruction of the damper. The danger is particularly great when closing in addition to the weight of the toilet lid (or toilet seat) a closing force, for example, by pressing down, added.

The invention has for its object to provide a damping arrangement which is compact and moreover has an improved service life.

• einem Dämpfer, der ein erstes und ein relativ zu dem ersten Ende drehbares zweites Ende aufweist,
• einer Hülse zur Aufnahme des Dämpfers, wobei der Dämpfer mit seinem ersten oder seinem zweiten Ende drehfest in Eingriff mit der Hülse steht,
• einem Endstück, das drehbar mit der Hülse verbunden ist und drehfest mit dem anderen Ende des Dämpfers in Eingriff steht,
• wobei das Endstück mit einem dem WC-Sitz und/oder dem WC-Deckel zugeordneten WC-Becken verbindbar ist und
• wobei der WC-Sitz oder der WC-Deckel drehfest mit der Hülse verbindbar ist.

According to the invention this object is achieved by a device for damping a toilet seat or a toilet lid, with

• a damper having first and second ends rotatable relative to the first end,
• a sleeve for receiving the damper, wherein the damper with its first or its second end is rotationally fixed in engagement with the sleeve,
• an end piece which is rotatably connected to the sleeve and rotatably engaged with the other end of the damper,
• wherein the tail with a toilet seat and / or the toilet lid associated toilet bowl is connected and
• wherein the toilet seat or the toilet lid is rotatably connected to the sleeve.

The invention combines several advantages over conventional damper arrangements. A major advantage is the stability of the construction with minimal space requirements. This advantage is created by the damper at least partially surrounding sleeve. Occurring during closing transverse forces do not act - as in conventional solutions - directly on the sensitive pin of the damper, but are directed into the sleeve, and from there via the tail (and usually a mounting pin) in the toilet bowl. The damper itself remains largely unloaded in the direction transverse to the axis of rotation. A long life is the result.
A further advantage of the invention lies in the ease of handling, in particular when the damper, the sleeve and the end piece can be joined together in one unit and the unit can be inserted into a receptacle in a toilet seat and / or a toilet lid, as appropriate. The combination of damper, sleeve and End piece can be made available to the end user pre-assembled. A mating of individual components on site can be omitted.

The sleeve is preferably made of metal, for example stainless steel, or made of hard plastic.

Advantageously, the sleeve has in its outer periphery a groove into which engages a circlip in the installed state, which serves to secure the sleeve in a receptacle of the toilet seat and / or toilet lid. This prevents the risk that the sleeve or the entire damper unit slides out of the toilet seat or lid. The circlip is not visible when installed. He sits, for example, in a recess in the toilet seat or cover, preferably directly at the joint between the toilet seat and toilet lid.

In an essential embodiment of the invention, it is proposed that the sleeve has a slot in its circumferential wall, through which a fastening pin engages in the end piece for securing the toilet lid or the toilet seat to the toilet bowl. The slot extends in the circumferential direction and prevents plug-in mounting pin slipping out of the tail of the sleeve. In the pre-assembly of the damper assembly of the mounting pin (possibly including mounting arrangement for the toilet bowl) can be connected to the damping device, which facilitates the subsequent final assembly on site again and especially reduces the number of "loose" parts.

The end region of the device according to the invention is free in the fully assembled state and is accordingly visible in certain positions of the toilet seat or cover. Preferably, therefore, the tail is inserted into the sleeve. This provides a particularly compact and aesthetically pleasing design, especially when the outer diameter of the end of the tail is adapted to the outer diameter of the sleeve. It should be noted, however, that designs are conceivable in which the end piece engages over the sleeve. The tail will then be sleeve-like at least in one section. In both cases, a pin inserted through the slot can fix the end piece in the sleeve.

Conventional dampers for damping rotary motion typically have at least one wing connected to the pivot which, upon rotation of the pivot, urges viscous fluid from one chamber to another chamber. By design, the angle within which the pivot is movable limited. When using two diametrically opposed wings, the angular range is set, for example, to 110 °. If the specified working range is exceeded, the damper can be destroyed. In WC's, the danger is particularly great, since the attacks in the open position of the lid and seat of toilet installation can vary to toilet installation and the leverage is significant, especially in a toilet seat or cover. Preferably, therefore, the slot limits the opening and / or the closing movement of the toilet lid or the toilet seat. This eliminates the risk that the damper will be "over-tightened" and destroyed. The slot provides a stop that stops the movement of the toilet seat or the toilet lid before reaching the critical angular position of the damper.

In principle, it may be advantageous to additionally secure the end piece to the fastening pin. A structurally favorable solution is characterized in that for fixing to the mounting pin in the tail a screw is arranged, which can be reached through the slot. The screw can be a grub screw. In an end position of the toilet seat or cover, the screw is covered by the outer wall of the sleeve. In the other end position - preferably the open position - the screw is accessible.

The sleeve expediently has on its outer circumference at least one profiled region which is in positive engagement with an associated region of the toilet seat or toilet lid. A development of the invention which is favorable in terms of good handleability is characterized in that the profiled area comprises at least one groove or a web or is formed as a flattening and that the associated area of the toilet seat or toilet lid acts as a web or groove or as Survey is formed. If the damping arrangement is not preassembled, for example, the damper and the sleeve is first inserted for mounting the entire device and the sleeve is "closed" by the end piece. The sleeve is then inserted together with the damper and the end piece as a compact unit in a integrally formed with the toilet seat or cover receptacle, wherein the grooves and webs ensure correct positioning of the unit in the circumferential direction. Furthermore, by the groove / webs a simple rotationally fixed connection can be created. Both the tail and the damper are easy and without the risk of misalignment mountable. The same applies, of course, when first the sleeve and then the damper is inserted. As an alternative to on-site assembly, the arrangement according to the invention allows a pre-assembly as described above, with only the entire assembly needing to be inserted into the receptacle (s) later for final assembly.

Between the tail and the inner wall of the sleeve, an O-ring may be provided. The O-ring prevents an already inserted end unintentionally released from the sleeve. Nevertheless, it offers only so much resistance that the tail can be easily removed to replace the damper.

The invention can be used for damping, for example, only a lid. As previously indicated, however, a common field of application is the simultaneous damping of toilet seat and toilet lid. For this purpose, a right-side and a left-side damper are required. To increase the safety during assembly of the device according to the invention it is provided that the groove or the web of a sleeve offset from the groove or the web of the other sleeve. It can be selected in each case a different angular distance. Thus, it is clearly defined which damping device is to be assigned to which side. Incidentally, a different cross-sectional configuration or width of the groove / webs is conceivable to uniquely determine the assignment.

When mounting the damping device in the receiving lug of the toilet seat or toilet lid, the correct positioning of the damping device in the circumferential direction plays an important role. It is suggested for a clear definition of the position that the Outer circumference of the sleeve is covered with at least two grooves or webs, which divide the outer periphery in different sized angle ranges. If, for example, two grooves are formed in the outer circumference, then the angular ranges should not be the same size, ie (idealized) 180 °, since otherwise two orientation possibilities of the damping device would be present.

For stability reasons, it may be advantageous if the tail protrudes into a sleeve receiving area of the toilet seat or the toilet lid. The sleeve receiving portion may be integrally formed at the rear end of the toilet seat or lid as described above. The tail needs to stand out only a small portion of the tab. Also, a stable arrangement is created by the largest possible attack area between the tail and the sleeve. The sometimes considerable lateral forces under load can thus be well absorbed.

The sleeve can in principle be varied. It has to take up the end piece (turnable) on one side and lock on its other side the pin of the damper or its opposite end. A particularly simple design of the sleeve is characterized in that one end of the sleeve has a frontal end a recess which provides an opening to the interior of the sleeve and serves to receive one end of the damper. Commercially available dampers often have flattened ends, so that one will choose, for example, a recess running perpendicular to the damper axis, which is particularly easy to produce from the outside.

The inventive device for damping a toilet seat or a toilet lid has according to FIG. 1 a first sleeve 1, a damper 2 received in the sleeve and a first end piece 3. The damper comprises a pin portion 4 and a cylinder portion 5 which is flattened at its end opposite the pin portion.

The end piece 3 has a bore 6 into which a toilet bowl assigned (not shown) mounting pin can be inserted for attaching the device to a toilet bowl. At its side facing the damper 3 carries the tailpiece two web-like projections 7 which engage around the flattened portion of the cylinder 5 and thus holds the cylinder portion in the circumferential direction. Between the sleeve 1 and the end piece 3, an O-ring 8 is arranged, which fixes the end piece in the sleeve and prevents unwanted sliding out. As a rule, the O-ring 8 will be arranged in a groove 3 associated with the end piece.

FIG. 2 shows the damping device after FIG. 1 in a perspective exploded view. For (pre-) assembly, the damper 2 is first inserted into the sleeve 1. He arrives with its pivot 4 in engagement with a formed in the sleeve complementary receiving portion 9, which is designed as a radial slot, which creates an opening to the interior of the sleeve. The pin 4 is thus always connected rotationally fixed to the sleeve 1. Subsequently, the end piece 3 is inserted together with the O-ring 8 in the sleeve 1, in such a way that the two web-like projections 7 engage around the flattened portion of the cylinder 5. Alternatively, an insertion of the end piece 3 together with already pre-assembled damper 2 in the sleeve 1 is possible. In any case, the assembly of the device according to the invention is very easy.

For a better understanding of the operation of the damping device should already be noted at this point that when installed a toilet seat or a toilet cover is in engagement with the sleeve 1. When the toilet lid or seat (not shown) is pivoted, the sleeve 1 - and thus also the pivot pin 4 - rotates while the end piece 3 connected with a ceramic is fixed and holds the cylinder portion 5 of the damper 2 in position. The Pivoting movement of the seat or lid is limited by a formed in the sleeve slot 10 in the peripheral wall of the sleeve 1, as will be explained in more detail below.

FIGS. 3 and 4 show a second embodiment of the damping device according to the invention. The second embodiment has an end piece 11, the two webs 12 now comprise the pin 4 of the damper 2. The damper 2 is accommodated in a sleeve 13 which has a recess 14 in its end region, through which, when the damper 2 is plugged in, the flattened portion of the damper is non-rotatably connected to the sleeve 13. Upon rotation of the sleeve 13, the cylinder portion 5 of the damper 2 rotates while the pin 4 is held by the end piece 11.

FIG. 5 shows the first embodiment as a left-side damping device and the second embodiment as a right-side damping device. As can be clearly seen, is in the left side embodiment, the tail with the cylinder portion 5 is engaged, while in the right-hand version of the pin 4 is encompassed by the webs 12 of the tail. Only schematically indicated are two integrally formed with a (not shown) toilet seat receptacles 14, 15 and two (also not shown) toilet cover associated receptacles 16, 17. Both the seat and the lid are in the closed position.

In the case of the left-side arrangement, the receptacle 17 assigned to the cover is in engagement with the sleeve 1. Thus, when the cover is pivoted, the sleeve 1 (and with the sleeve 1 also the pin 4) rotates. The cylinder section 5 the damper 2 remains stationary. The seat associated with the receptacle 15 slides in a pivoting of the seat on the sleeve 1 from.

In the right-hand arrangement, the receptacle 14 assigned to the seat is non-rotatably connected to the sleeve 13. If the seat is pivoted, the sleeve 13 rotates and takes the cylinder portion 5 of the damper, while the pin is held by the end piece 11. The lid receptacle 16 slides on pivoting of the lid on the sleeve 13 (the lid is, however, as described in the section previously damped on the left-side arrangement).

A great advantage of the invention is that the damper used 2 - and in particular their pin 4 - are charged only in the direction of rotation. The z. T. considerable lateral forces are absorbed by the sleeve 1, 13 and passed over the end piece 3, 11 in the toilet bowl or ceramic. The life of the damper is significantly increased over comparable conventional designs.

The FIGS. 6 and 7 show the sleeve 1 of the first embodiment in isolation. When assembled, the damper (not shown) rests against a stop 18 (see FIG FIG. 6 ), wherein the pin of the damper engages in the formed as a radial slot receiving portion 9 of the sleeve 1, which creates a breakthrough to the interior of the sleeve.

The sleeve 1 has on its outer side a groove 19 which allows an accurate positioning of the sleeve - and thus of the damper. In the groove 19 engages an associated in one of the receptacles 15 or 17 trained web. It can also be provided several grooves / webs. Although the grooves / webs with suitable training for transfer provide the torque required positive rotational engagement, but their task is primarily in the positioning of the sleeve. The actual engagement for power transmission creates a flattening 20, which is formed by the formed as a radial slot receiving portion 9. In the flat 20 engages a (not shown) the toilet seat or toilet cover associated web.

The FIGS. 8 and 9 show the sleeve of the second embodiment in isolation. When assembled, the damper (not shown) is located on a stop 21 (see FIG. 8 ), wherein the flattened portion of the cylinder portion of the damper engages in the formed as a radial slot receiving portion of the sleeve 13, which creates an opening to the interior of the sleeve. On the outside of the sleeve one or more grooves 22 are formed, engage in the associated formed in one of the receptacles 14 or 16 webs. If the grooves 19 and 21 are distributed differently over the outer circumference of the sleeve, a safeguard against insertion of the sleeve in the wrong side can be avoided. Also, a different cross-sectional shape or width of the groove and webs can have the same effect. The actual power transmission takes place via a flattening 23 and optionally via an opposite flattening 24 into which a web 25 of the toilet seat (see the right-side damper arrangement in FIG FIG. 5 ) or a web of the toilet lid engages.

FIG. 10 shows a further pair of damping devices according to the invention in an exploded perspective view, which is adapted to another form of damper 2.

The left-side damping device arranged in the figure above and the right-side damping device have identical end pieces 26. The two sleeves 27 and 28 are also formed with sleeve ends open on both sides, wherein the sleeve 27 receives the pin 4 opposite portion of the damper, while the sleeve 28 defines the pin 4. In the outer wall of the sleeve 27 grooves 29 are formed, which with webs 30 (see FIG. 11 ) are engaged. It is steamed the toilet lid. The recording associated with the toilet ring slides on a pivoting movement on the sleeve.

Conversely, in the upper arrangement of the toilet seat is attenuated. Here are grooves 29 with the toilet seat associated webs 31 (see FIG. 11 ) engaged.

FIG. 11 shows both damping devices mounted.

It will open FIG. 12 Referring to the in a sectional view of an embodiment similar to that of FIG. 1 is shown. Between an end piece 32 and a sleeve 33 of the damper 2 is received, wherein two webs 341 engage around the flattened portion of the cylinder 5. The sleeve 33 is engaged with the pin 4 of the damper 2 and thus creates a rotationally fixed connection. In the outer wall of the sleeve 33, a groove 34 is formed, in which a (not shown) retaining ring is inserted, which is a sliding out of the unit 33, damper 2 and end piece 32 from the receptacle of the (not shown) toilet seat or Toilet lids prevented. The retaining ring is placed in a recess in the toilet seat or in the toilet lid, preferably in the region of the joint.

As it's best from the FIGS. 13 to 15 can be seen, is for fixing the tail on a mounting pin a screw 35 is provided, which is screwed radially into the end piece. From the FIGS. 14 and 15 It is clear that the screw is accessible even when the end piece, via a slot 36 which limits the rotational movement of the sleeve 33 when the fastening pin is inserted. The screw 35 is screwed so far into the tailpiece for attachment to the mounting pin that the sleeve can slide freely on the tail.

The FIGS. 16 to 19 show a the embodiment according to FIGS. 12 to 15 configured embodiment, but in the present case a right-side damping device. For simplicity, the same reference numerals as in the FIGS. 12 to 15 chosen, and it is so far referred to the associated description of figures.

In the context of the invention modifications are possible. For example, for stability reasons, the device according to the invention can be completely integrated in the receptacle. The arrangement can be made so that only the end of the tail is visible. Also, the end piece may be directly formed with a pin and e.g. be connected via a bayonet-type closure with the sleeve. However, the mounting hole shown corresponds to the rule. Moreover, the device according to the invention can be used both as a right-side and as a left-side damping device and is not limited to the illustrated shape of the receptacles of the seat and lid.
