Abstract

In order to ensure a high standard of hygiene even without the intervention of the toilet user, a method for actuating a toilet seat and cover arrangement (2, 3) and an actuating device for a toilet seat and cover arrangement (2, 3) are proposed. According to the method, the toilet seat (2) and the toilet lid (3), in the case of use while standing, are automatically lowered again into the closed position after a predetermined time, while in the case of a seated use, after their termination, the toilet seat (2 ) is automatically raised again to the open position, whereupon the toilet seat (2) and the toilet lid (3) are automatically lowered again into the closed position. A purely mechanical-hydraulic actuating device of a toilet seat and lid arrangement (2, 3) , is presented with which the method can be carried out. Because the components of the actuating device are all housed in a closed cavity in the toilet lid (3), there is no need for an external energy and / or control connection including cable or pipe connections, nor is there any need for any components on the outside of the toilet seat and lid arrangement ( 2, 3). This is because of its largely smooth surfaces easy to clean and hygienically clean.

Description

The invention relates to a method for actuating a toilet seat and lid arrangement according to the preamble of claim 1 and an actuating device of a toilet seat and lid arrangement according to the preamble of claim 2.

A method according to the preamble of claim 1 is known from the WO 01/93737 A1 known.
In the toilet set disclosed in this document, the toilet seat and toilet lid remain in the position in which they were left after use, provided they are not closed again by the user by hand. However, since it is not ensured that every user performs this manual closing, at least the toilet lid can consequently remain in the open position. A toilet that is not closed is often perceived as unsightly. In addition, there is the possibility that the toilet is left with the lid open but the toilet seat lowered, and a subsequent user urinates standing up without first lifting the toilet seat, which can lead to undesirable drops on it.
It can also happen that after cleaning the toilet bowl when moving the toilet brush back when moving over the toilet rim, drops fall from the toilet brush onto the toilet seat if it has not been opened by hand after using the toilet for cleaning.

An actuator of a toilet seat and lid assembly according to the preamble of claim 2 is from the DE 202 16 128 U1 known.
This document discloses a toilet seat and lid arrangement which has such an opening device that the toilet lid and / or the toilet seat automatically swings into the open position in response to a trigger signal (for example, a light touch is sufficient) in order to avoid that the toilet seat and - the lid arrangement must be folded up manually. The automatic opening of the toilet seat and lid arrangement can be brought about with the force of a spring which is arranged in the hinge area and is drawn onto a support rod. It remains to be seen how the toilet seat and lid arrangement should be returned to the closed position after using the toilet.

The invention is based on the object of avoiding the disadvantages described above and of specifying a method in which a great hygiene standard is ensured even without the intervention of the toilet user. Furthermore, an actuating device of a toilet seat and lid arrangement is to be presented, with which such a hygienic actuation of the toilet seat and lid arrangement is possible without an external energy connection.

From the DE 20 2008 003 203 U1 a device with an electrical control for automatically closing a toilet lid is known. This is designed in such a way that the device closes the toilet lid when the toilet is not used in a sitting position after the manual opening and / or after the cistern has finished filling in a specific, freely selectable period of time.

From the DE 10 2014 003 767 A1 a toilet, in particular aircraft toilet, each with a drive device for automatically moving the lid and the toilet seat between the closed and open positions is known. The two electromotive drive devices can be operated independently of one another and are controlled by the user via an operating device.

The DE 20 2008 006 689 U1 a procedure can be found in which the toilet lid and toilet seat can be opened manually at the same time. The document discloses a specially designed toilet handle with two levers.

1. 1. WC-Deckel öffnen oder schließen,
2. 2. WC-Brille öffnen (nachdem zuvor der WC-Deckel geöffnet wurde) oder WC-Brille schließen (vor Schließen des WC-Deckels)
3. 3. WC-Deckel und -Brille gleichzeitig öffnen oder schließen.

The DE 20 2008 012 385 U1 shows a device for the automatic opening and closing of toilet lid and glasses by means of a control panel controllable electric motors. The following process variants are taught:

1. 1. Open or close the toilet lid,
2. 2. Open toilet glasses (after opening the toilet lid) or close toilet glasses (before closing the toilet lid)
3. 3. Open or close the toilet lid and glasses at the same time.

The DE 20 2009 008 084 U1 discloses a toilet seat with a motor-driven, automatically rotating toilet lid. In an operating mode described in the document, the toilet lid and toilet seat are opened and closed together in order to ensure that the toilet seat remains clean when urinating.

From the US 9 532 686 B1 (as from the unpublished continuation of application in US 10 455 995 B1 ) a toilet seat and cover arrangement together with its actuation method is known. It is taught to place the power source, electronics, and mechanical actuator in the lid. Tilt and position sensors determine the positions of the seat and lid. Distance or proximity sensors detect when the toilet is not in use and after a delay the actuator selectively moves the seat or lid to a closed position.

The object described above is achieved by a method according to claim 1 and by an actuating device according to claim 2.

The fact that in a first phase (due to a suitable constructive design) the toilet seat and lid can only be brought into the open position by hand, so that the toilet can only be used when standing (so-called first case) when the toilet seat is open .
In order to ensure that a subsequent user can only use the toilet while standing in order to further avoid urine splashes on the toilet seat when the toilet seat is open, it is proposed according to the invention that the toilet seat and lid are automatically automatically returned to the closed position after a predetermined time after opening Position to be lowered. The specified time is to be matched to a usual duration of use plus a time surcharge.

Due to the fact that in the so-called second case (toilet is used when seated) the toilet seat is automatically raised again to the open position after the use of the toilet has ended, it is possible to clean the toilet bowl when the toilet seat has already reached a larger opening angle , without running the risk of soiling the toilet seat with drops from the cleaning brush. For this purpose, the lifting speed of the toilet seat can be variably provided via the opening angle (lower lifting speed in the area of larger opening angles) and must be matched to the usual duration of a cleaning process, at least in the area of larger opening angles.
As an alternative or in addition to the variation of the lifting speed, it is also possible to take a time break after reaching a larger opening angle of the toilet seat or in its fully open position, until the subsequent automatic lowering of the toilet seat and lid into the closed position.

Because the actuating device according to the invention is constructed purely mechanically and hydraulically and all components are arranged in a closed cavity in the toilet lid, there is no need for an external energy and / or control connection including cable or pipe connections, nor is there any need for any components anywhere on the outside to arrange the toilet seat and lid assembly. As a result, the toilet seat and lid arrangement has largely smooth surfaces that are easy to clean and keep hygienically clean.

Advantageous developments of the actuating device according to the invention are characterized in the subclaims 3 to 10.

Further features, details and advantages of the invention will become apparent from the following description of an embodiment with the aid of a drawing.

1 ac and 2a-f show a toilet consisting of toilet bowl 1 , Toilet seat 2nd and toilet lid 3rd . The toilet seat 2nd and the toilet lid 3rd are on a common spindle 4.1 around the axis 4th pivoted. The axle mandrel 4.1 again ends at its two ends in lateral holding devices 5 , directly or with the interposition of an adapter to adapt to the hole spacing of the toilet bowl 1 are attached to this.

How out 1a and in particular the associated detailed representation is the toilet seat and lid arrangement 2nd , 3rd constructively designed such that the toilet seat 2nd and the toilet lid 3rd can only be lifted by hand from the closed position. This is the toilet lid 3rd constructed in such a way that it has no possibility of intervention and has a smaller circumference to the side and to the front than the toilet seat 2nd . The toilet lid is in the closed position 3rd flush on the toilet seat 2nd on. A manual intervention to open can only under those with support elements 6 provided toilet seat 2nd take place, the support elements 6 a vertical distance between the toilet bowl that enables manual intervention 1 and toilet seat 2nd produce.
Because of the toilet lid 3rd has a smaller circumference on the sides and front than the toilet seat 2nd , the latter so visible over the edge of the toilet lid 3rd protrudes, it allows the toilet seat 2nd from the in picture 1b shown, open position, manually fold down for a seated use of the toilet.

In the following, the 1a-c and 2a-f the movement sequences in the method according to the invention for actuating the toilet seat and lid arrangement 2nd , 3rd are explained. It is in the 1a-c the sequence of movements when using the toilet is shown in the 2a-f the sequence of movements when seated.

In the first phase there will be a toilet seat 2nd and toilet lid 3rd together, after an intervention under the toilet seat 2nd , (see detailed illustration in 1a) raised by hand and from the closed position ( 1a) in the in 1b shown open position brought. This movement should be shown by the two arrows in 1b be represented symbolically. An arrow represents the movement of the toilet lid 3rd , the other for the movement of the toilet seat 2nd . This also applies analogously to the arrow representations in the other partial figures of 1 and 2nd .
Toilet covers remain in this open position 3rd and toilet seat 2nd first.

In a first case, the toilet can be used standing up without the toilet seat 2nd can be contaminated by splashes when urinating. After a specified period of time, toilet lids become 3rd and toilet seat 2nd automatically brought back into the closed position without user intervention by a (not yet shown) installed and / or attached actuating device, as in 1c shown. The toilet is ready for the next user.
The duration of the time specified above, in the toilet lid 3rd and toilet seat 2nd kept open can, for example, be matched to the usual duration of standing toilet use plus a "safety surcharge" and can be easily determined by experiments. For example, it can be between 2 and 5 minutes.

If, as an alternative to the so-called first case described above, the person wishes to use the toilet while sitting (“second case”), then in the first phase, as in the case of standing use described above, they will manually use the toilet seat 2nd and toilet lid 3rd together, after an intervention under the toilet seat 2nd , lift, and from the closed position ( 2a) in the in 2 B bring shown open position, because it is due to the above-described design of the Toilet seat and lid arrangement 2nd , 3rd is not possible, only the toilet lid 3rd lifting alone.
After that, as in 2c shown, only the open toilet seat 2nd alone by hand again to the horizontal position (shown in dashed lines), with the above-described protruding edge of the toilet seat 2nd over the toilet lid 3rd , the required gripping only of the toilet seat 2nd allows for lowering.
The toilet can now be used while seated. The sitting person becomes the toilet seat 2nd held in the lowered, horizontal position in which the support elements 6 on the toilet bowl 1 lie on. As long as the toilet seat 2nd is in the lowered position, the toilet lid 3rd blocked in its open position; it cannot lower itself, not even after the above "specified time" has expired.
After the sedentary use of the toilet has ended, the toilet seat 2nd relieved of the weight of the user and then slowly raised again by the (not shown here) built-in or attached actuating device without the user having to do anything from the horizontal position, as in 2d represented up to, in 2e shown, open position, in the toilet seat 2nd and toilet lid 3rd rest against each other again.

In this open position, the toilet seat and lid assembly can 2nd , 3rd linger for a definable time in which it is possible to use the toilet bowl 1 to clean with a toilet brush. After the definable time, toilet lids become 3rd and toilet seat 2nd automatically brought into the closed position by the (not shown) installed and / or attached actuating device without the user having to do anything, as in 2f shown. The toilet is ready for the next user.

Alternatively, instead of lingering the toilet seat and lid assembly 2nd , 3rd in the open position for cleaning the toilet bowl 1 also be provided the speed of the upward movement of the toilet seat 2nd When reaching a larger angle, reduce it so much that the cleaning starts during the slow upward movement of the toilet seat 2nd can be carried out. Lingering the toilet seat and lid assembly 2nd , 3rd in the open position is then no longer necessary, but can be reached after reaching the fully open position and touching the toilet seat 2nd and toilet lid 3rd ( 2e) pass without further pause into the common closing movement that occurs when the in 2f shown closed position ends.

Because the toilet seat during the cleaning process 2nd from the toilet bowl 3rd is lifted and is approximately vertical, (or according to the above alternative has at least a large angle) there can be no contamination of the toilet seat 2nd come off the brush due to dripping or splashing water.

The method described above for operating the toilet seat and lid assembly 2nd , 3rd can in principle be carried out using various built-in or attached actuators, such as electrically using electromagnetic, electromotive, pneumatic or hydraulic actuators in connection with an electrical or electronic control. A purely pneumatic actuation device is also conceivable. Here, however, the use of a purely mechanical-hydraulic actuation device should be preferred, which has the advantage of working completely independently of any electrical connection, accumulator, battery or other connection for energy or actuation medium.

Such a mechanical-hydraulic actuating device for carrying out the described method for actuating the toilet seat and lid arrangement 2, 3 is described below with reference to the other figures.

In the 3rd - 7 the basic structure of a mechanical-hydraulic actuating device is shown. This is inside a cavity in the toilet lid 3rd installed, for which the toilet lid 3rd in two parts with at least one arched part, for example the top part of the toilet lid 3.1 , is constructed. Alternatively, but not shown here, the toilet lid 3rd can also be provided in one piece with a bulbous front opening for the actuating device. After assembly of the components in the cavity of the toilet lid, the toilet lid is closed, so that only more or less smooth surfaces are present on the outside, which enables hygienic cleaning of the toilet seat and lid arrangement.

The view in the 3rd - 7 is always perpendicular to the underside of the top part of the toilet lid 3.1 no matter what position (closed, open or partially open) it is. The toilet lid 3rd is there (assuming two-part design of the toilet lid 3rd ) with the second part removed, the lower part of the toilet lid, so that you can see the inside of the upper part of the toilet lid 3.1 with its internals.
In 3rd to 7 is the numbering of the components with reference numerals for reasons of simplified representation only in 3rd has been completely made. Of course there are missing Reference numerals in the 4th - 7 based on 3rd transferred to.
This applies mutatis mutandis to the other figures.

3rd shows the view with the toilet seat and lid arrangement 2, 3 closed from the perspective of the toilet bowl 1 out how in 3a indicated by the arrow. On the fixed arbor 4.1 with side holding devices 5 directly or, if necessary, with the interposition of an adapter to adapt to the hole spacing of the toilet bowl 1 attached to this are between the two holding devices 5 on the outside right a toilet seat socket 7 and another toilet seat socket on the outside left 7.1 rotatably mounted. The toilet seat 2nd , of which for the sake of illustration only parts with two support elements 6 is shown, with two toilet seat bushings 7 , 7.1 rigidly connected so that when lifting and lowering the toilet seat 2nd a rotational movement in relation to the fixed axle mandrel 4.1 around the axis 4th To run.
Connect axially inwards to the toilet seat bushings 7 , 7.1 are two with the toilet lid 3rd or (with two-part design of the toilet lid 3rd ) the top of the toilet lid 3.1 rigidly connected toilet lid sockets 8th , 8.1 also rotatable around the fixed axle mandrel 4.1 arranged.

Between the two toilet lid sockets 8th , 8.1 is a fixed axis mandrel centerpiece 4.2 intended. It can be done with the axle mandrel 4.1 be formed in one piece, or designed as a separate component and with the axle mandrel 4.1 be rigidly connected. Because the axle mandrel centerpiece 4.2 a larger cross section than that of the toilet seat bushings 7 , 7.1 and the toilet lid sockets 8th , 8.1 included areas of the axis mandrel 4.1 has, there is a stop against axial displacement of the toilet seat 2nd and toilet lid 3rd .
At the centerpin of the axle mandrel 4.2 are two connecting rods 23 radial to the axis 4th articulated, namely by means of two axially fastening bolts 25th that are parallel and eccentric to the axis 4th are arranged progressively. The representation in 3rd shows the articulation on the left in a breakout from the center pin of the axle mandrel 4.2 , the articulation on the right is shown in dashed lines because it is hidden. The other ends of the connecting rods 23 are by means of support bolts 24th on a substantially cuboid support slide 17th attached to one in the top of the toilet lid 3.1 trained bed 20th is arranged to be longitudinally displaceable. The two connecting rods 23 are around the axle mounting bolts 25th and around the support-side fastening bolts 24th rotatable. When opening the toilet lid 3rd leads the latter together with the toilet lid sockets 8th , 8.1 a rotational movement around the axis 4th off while the drive rods 23 due to their eccentric articulation on the fixed axis mandrel center piece 4.2 the support sled 17th in bed 20th from its in 3rd Move the lower end position shown in the picture up to its upper end position with the toilet lid open 3rd .
This is also from the illustration in 4th can be seen that the conditions when the toilet seat and lid arrangement 2, 3 are open 4a shows. The line of sight is in 4a again represented by an arrow for clarity.
The position of the support carriage 17th is only from the position of the toilet lid 3rd dependent.

To illustrate the linkage of the drive rods 23 to the center arbor spine 4.2 and on the support sled 17th is this in the 10a and 10b shown in section. Exemplarily for those in the 3rd to 7 left connecting rod 23 , with the cut in the 3rd and 4th through the dashed line C - C is marked. 10 a shows the position with the toilet lid closed 3rd according to 3rd . 10 b shows the position with the toilet lid open 3rd corresponding 4th (but also 5 and 6). As in the 10a and 10b can be seen, shows the axis mandrel center piece 4.2 a milled out 4.3 to accommodate the drive rod 23 on. The connecting rod 23 is in turn in the side cheeks of the milled 4.3 mounted mounting pin on the axis mandrel 25th eccentric on the centerpiece of the axle mandrel 4.2 rotatably attached. Using the support-side fastening bolt 24th is the connecting rod 23 on the support sled 17th also rotatably attached. Obvious ( 10a) is in the closed position of the toilet lid 3rd the support sled 17th retracted to its lower end position while in the open position of the toilet lid 3rd ( 10b) due to the axis 4th eccentric linkage of the drive rod 23 on the centerpin of the axle pin 4.2 is extended to its upper end position.

It should be noted that it is also conceivable in principle to use the support sled 17th only by means of a single drive rod 23 with the center pin mandrel 4.2 to be connected, if by constructive measures known to the person skilled in the art (eg extra long guideway in bed 20th ) it is ensured that the support sled 17th cannot perform any tilting movements.

Back to 3rd : At the left end of the right toilet seat socket 7 is a rolling link on part of its circumference 9 trained on which a belt drive 10th forming closed, endless belt 11 by means of a belt connection pin 12 is articulated.
A detailed view of the toilet lid 3rd built-in belt drive 10th is also the 8a-c can be seen which is a section along the through the two arrows A - A in the 3rd to 5 show marked lines, whereby for better visibility and clarity in the 8a-c Simplifying partly on hatching of components (e.g. the drag linkage 16 , the spring plate 19th ) and on dashed lines (e.g. the invisible part of the fork head 15 ) was waived. This representation, which does not strictly follow the rules of technical drawing, nevertheless allows structure and functional relationships to be clearly and unambiguously recognized.

This also applies analogously to cuts shown in other figures.

The basic structure of the belt drive 10th and the components interacting with it is first based on the 3rd and the corresponding one 8a described, which the conditions with closed toilet seat and - lid assembly 2, 3 acc. 3a demonstrate.
The following applies to the further description: 4th corresponds with 8b (Conditions when the toilet seat is fully open 2nd and toilet lid 3rd acc. 4a) and 5 corresponds with 8c (Conditions with the toilet lid open 3rd and lowered toilet seat 2nd acc. 5a) .

The strap 11 is with the strap connecting pin 12 on the toilet seat socket 7 fixes and wraps around a part circle of the toilet seat socket 7 , attached to the rolling link 9 ; further wraps around an axially fixed deflection roller 13.1 , (in 3rd not visible because of the axis mandrel 4.1 and the toilet seat socket 7 concealed) on a projection of the axle mandrel 4.1 (alternatively: on a protrusion of the axle mandrel center piece 4.2 ) is stored. The strap 11 will continue over two toilet lid fixed pulleys 13 ( 8a) led, which in the top of the toilet lid 3.1 trained bed 20th ( 3rd ) are attached and finally wraps around a support roller 14 that on one with a longitudinally movable towing rod 16 connected clevis 15 is stored. The drag linkage 16 penetrates with play in the bed 20th longitudinally guided support sled 17th , on which there is one end with one, which is the towing rod 16 comprehensive first helical compression spring 18th supports. The other end of the first helical compression spring 18th is on one on the tow bar 16 trained spring plate 19th stored so that the first helical compression spring 18th with relative movements between towing linkage 16 and support sled 17th is relaxed or relaxed.
The upper part of the towing rod in the picture 16 is playing with one in bed 20th trained implementation 21st guided ( 3ff ) and has a tow hook at its end 22 on which a stop for a housing (damper cylinder 30th ) of a hydraulic damper 29 forms, which is part of a spring-damper arrangement, which will be described in more detail later. Damper cylinder 30th and drag hooks 22 are designed so that the damper cylinder 30th from the tow hook 22 against the spring force of one between support slides 17th and the face of the damper cylinder facing this 30th clamped, second helical compression spring 28 can be applied.

The position of the towing hook 22 is only from the position of the toilet seat 2nd dependent. In the closed position of the toilet seat 2nd it is in its lower end position near the bushing 21st , please refer 3rd , with the toilet seat open 2nd in its upper end position, removed from the implementation 21st , please refer 4th .

In the closed (initial) position of the toilet seat and lid assembly 2, 3, as in the 3rd and 8a is shown is the first helical compression spring 18th relaxed because the toilet lid is closed 3rd the support sled 17th is in its lower end position, as is the tow hook 22 together with the drag linkage 16 and the spring plate 19th when the toilet seat is closed (lowered) 2nd are in their lower end position.

Due to the constructive design of the rolling link 9 can influence the movement parameters of the toilet seat 2nd during its automatic movements (non-manual movements). For the sake of illustration, the 8a - c the cross section of the rolling link 9 simplified simply as increasing in scope and exaggerated for clarity. In fact, tests have shown that it can also be advantageous for the movement sequence in the automatic closing if the rolling link 9 is partially designed as a straight line, just as it can be advantageous if the rolling link 9 has a kink or even a small bead, in particular at the transition from said straight line to a round cross section. Experts can determine the exact design of the rolling link on the basis of tests.

It should be noted that in the 3rd to 7 for reasons of a simplified representation only the toilet seat socket on the right in the picture 7 with a rolling backdrop 9 and a belt drive interacting with it 10th to 8a-c is shown. In fact, the additional toilet seat socket on the left can also be used 7.1 just as with an identical rolling link, a belt drive interacting with it 10th after the 8a-c and another drag linkage 16 including drag hook 22 be provided, the two towing linkage 16 or the tow hook 22 can then be mechanically connected to one another via a constructive bridge, but not necessarily.

In the closed (initial) position of the toilet seat and lid arrangement 2, 3 as in the 3rd and 8a shown, is the location of the linkage of the belt 11 to the toilet seat socket 7 , 7.1 by means of the belt connection pin 12 radially approximately opposite the guide roller fixed to the axis mandrel 13.1 , please refer 8a . When opening the toilet seat together in the first phase of using the toilet 2nd and toilet lid 3rd the toilet seat bush rotates 7 , 7.1 around the axis 4th in the representation in 8a counterclockwise about 90 degrees into the in 8b position shown. This will be on the unrolling backdrop 9 overlying length of the belt 11 shortened so that the free, over the idler 14 leading length of the belt 11 enlarged, and the idler 14 including drag linkage 16 and drag hooks 22 under the effect of the first helical compression spring 18th is extended into the upper end position. Out 8b are the ratios of the belt drive 10th in the open (end) position of the toilet seat 2nd and toilet lid 3rd evident 4th shows the corresponding position of the towing hook 22 and the towing rod 16 including spring plate 19th . Because, as already explained above, because of the opened toilet lid 3rd also the support sled 17th is in its upper end position, is the first helical compression spring 18th relaxed.
The position of the idler 14 in the closed position of the toilet seat 2nd and toilet lid 3rd is in 8b drawn for comparison, the path by which the idler roller is drawn 14 including drag linkage 16 when opening toilet seat 2nd and toilet lid 3rd is extended, symbolically represented with an (lateral) arrow.

The positions as in the 4th and 8b shown, are taken for a few minutes when using the toilet while standing (see also explanations for 1b) , in a second case, in which the toilet is to be used while sitting, only for a short time until the toilet seat 2nd is manually lowered again during the toilet lid 3rd remains open.

In this second case, the toilet seat is lowered manually 2nd following, in the 5 and 8c shown conditions in the belt drive 10th : By lowering the toilet seat 2nd connected (back) rotation of the toilet seat bushing 7 , 7.1 the location of the belt linkage also comes into the closed starting position 11 to the toilet seat socket 7 , 7.1 by means of the belt connection pin 12 again radially approximately opposite the guide roller fixed to the axis mandrel 13.1 to lie the strap 11 is accordingly due to the rolling backdrop 9 the free length of the belt 11 has shortened and the idler 14 has been drawn into the lower end position. The shortening is in 8c again represented by an arrow.

In fact, the idler moves 14 in this described second case (toilet lid 3rd open, toilet seat 2nd lowered) even slightly above that when the toilet seat and lid arrangement 2, 3 is closed according to FIGS 3rd and 8a reachable lower end position and pulls the tow hook 22 a little further down, as well as a comparison of the positions of the towing hook 22 towards the implementation 21st in the 3rd and 5 shows. This effect is due to the fact that the toilet seat 2nd the toilet lid is closed 3rd but stays open. As a result, like a comparison of the 8a and 8c it becomes clear, a larger section of the second part of the belt on the right in the picture 11 to the unrolling backdrop 9 than when the toilet seat and lid arrangement 2, 3 is completely closed.
The effect described in 8c due to the exaggerated shape of the rolling link for clarification 9 appears more strongly than is actually the case, has no significant effects in the present case, as practice has shown, and is therefore negligible here.
In principle, however, it is quite possible to influence the movement characteristics of the toilet seat and lid arrangement 2, 3, in particular the movement characteristics of the toilet seat 2nd to be used during automatic lifting. Accordingly, the shape of the rolling link can 9 , the location of the belt connection pin 12 , the spring characteristics, as well as the positioning of the pulleys if necessary 13 and 13.1 adjusted and coordinated.

In the position: open toilet lid 3rd but closed (lowered) toilet seat 2nd like in the 5 and 8c shown is the first helical compression spring 18th maximum tension, because with the toilet lid open 3rd is the support sled 17th in its upper end position and the tow hook 22 including drag linkage 16 and spring plate 19th when the toilet seat is closed (lowered) 2nd in the lower end position.

Referring to 3rd are the structure and function of the spring-damper arrangement 28 , 29 described. This is between one on the top of the toilet lid 3.1 trained fixed camp 27th and the support sled 17th arranged. One with one end at the fixed camp 27th articulated piston rod 26 of the hydraulic damper 29 penetrates the two faces of the damper cylinder in a sealed manner 30th and ends free. The damper cylinder 30th is at its lower end in the picture via a second helical compression spring 28 on the support sled 17th supported.

Will the toilet seat and lid assembly 2nd , 3rd in the first phase of use from the closed position ( 3rd ) raised and into the in 4th brought open position shown, the support slide 17th by means of the drive rods 23 transferred to the upper position in the picture, between the support sled 17th and the face of the damper cylinder facing him 30th clamped, second helical compression spring 28 curious; excited. At the same time, the belt drive 10th in cooperation with the first helical compression spring 18th the drag linkage 16 including drag hook 22 in the picture shifted up, the tow hook 22 gives the damper cylinder 30th free. This can now be under the action of the second helical compression spring 28 move damped up. In 4th is the damper cylinder 30th shown in a position already slightly moved out of its lower end position, in which it is virtually “on the way”.

The spring damper assembly 28 , 29 is dimensioned and matched so that the movement of the damper cylinder 30th upward (pressure stage) runs very slowly and takes a few minutes from its lower end position to its upper end position, eg 5 minutes. But 2 minutes or times in between are also conceivable. Throughout this time there are toilet lids 3rd and toilet seat 2nd after opening by hand in its open position, the toilet is usable.

In the lower area of the damper cylinder 30th is a stop ring on its circumference 32 trained (see 3rd ) with a release hook 34 cooperates. Comes with the (strongly damped) upward movement of the damper cylinder 30th the stop ring 32 with the release hook 34 in contact and pulls it slightly upwards, this releases with a release hook 34 connected release hook linkage 33 a rear light 39 out of closing the toilet lid 3rd (and thus also the toilet seat 2nd ) initiates. The exact structure and mode of operation of this rear light 39 will be related to later 9 described in detail.

First, however, is again on the function of the towing hook 22 to deal with, in connection with the so-called "second case" of using the toilet described above, in which after manually lowering the toilet seat 2nd the toilet is to be used while sitting, taking the toilet lid 3rd of course as long as it has to remain in the open position. The latter is done with the help of a tow hook 22 ensured.

The situation: open toilet lid 3rd and closed (lowered) toilet seat 2nd is in the 5 and 8c shown and has already been described above: The support slide 17th is then in the upper end position (because of the opened toilet lid 3rd ), the drag hook 22 including drag linkage 16 and spring plate 19th in the lower end position and is by the on the toilet seat 2nd seated person also held there. The second helical compression spring 28 is like the first helical compression spring 18th fully excited.
Through the contact in the lower end position with the upper end face of the damper cylinder 30th located towing hook 22 is in this position of toilet seat 2nd and toilet lid 3rd the damper cylinder 30th as long as prevented from working under the action of the second helical compression spring 28 to move up like the toilet seat 2nd is in the closed (lowered) position. Consequently, the stop ring 32 of the damper cylinder 30th not in contact with the release hook 34 kick and close the toilet lid 3rd introductory rear light 39 trigger. The toilet lid 3rd thus remains safely in the open position.

The user stands up after using the toilet and gives the toilet seat 2nd free, it moves automatically due to the accumulating forces of the first helical compression spring 18th and the second helical compression spring 28 steamed up from the closed (lowered) position. This situation with the toilet seat already slightly raised 2nd is in the 6 and 6a shown, wherein in 6a the dashed arrow indicates the direction of movement of the toilet seat 2nd indicates the solid arrow again the direction of view.
The first helical compression spring 18th and the second helical compression spring 28 are each dimensioned such that the force alone of one of the two springs 18, 28 is not large enough, the toilet seat 2nd to raise.
The relaxing second helical compression spring 28 acts via the damper cylinder 30th up in the picture on the tow hook 22 , this on the tow bar 16 , supported by the also relaxing first helical compression spring 18th . The total force of both springs 18th , 28 works via the belt drive 10th , the belt connecting pin 12 and the rolling backdrop 9 on the toilet seat socket 7 which the toilet seat attached to it 2nd lifts. Because of the damping effect of the damper 29 on the relaxation force of the second helical compression spring 28 the toilet seat opens 2nd slowly.

Comes with the upward movement of the damper cylinder 30th finally the stop ring 32 with the release hook 34 in touch (what happens when the toilet seat is approximately vertical 2nd is the case) and pulls it slightly upwards, this is released by using the release hook 34 connected Release hook linkage 33 a rear light 39 (see 9a-d ) from closing the toilet lid 3rd initiates, which in turn the toilet seat 2nd takes along. This situation is in the 7 and 7a shown, in the illustration the toilet seat and lid arrangement 2, 3 has just started with the common closing movement and the release hook 34 already from the stop ring 32 has lifted off.

• Dazu wirken zusammen:
  • ein ebenfalls im Toilettendeckel 3 angeordneter Schließdämpfer 35,
    • - der Dämpfer 29 in Verbindung mit dem Schlepphakengestänge 16 samt dem Schlepphaken 22 und dem Riementrieb 10, sowie
    • - ein Koppelmechanismus 57.

Also the automatic joint closing movement of the toilet lid 3rd and toilet seat 2nd is steamed:

• To do this work together:
  • one also in the toilet lid 3rd arranged locking damper 35 ,
    • - the damper 29 in connection with the drag linkage 16 together with the tow hook 22 and the belt drive 10th , such as
    • - a coupling mechanism 57 .

• Es ist ein Schließdämpfer 35 (siehe 3) vorgesehen, der im Prinzip gleich oder ähnlich aufgebaut sein kann, wie der bereits beschriebene Dämpfer 29. Insbesondere kann der Schließdämpfer 35 einen Schließdämpferzylinder 37 aufweisen, der im im Toilettendeckel 3 ausgebildeten Bett 20 fixiert ist. Eine Kolbenstange 36 trägt einen einseitig wirkenden Schließdämpferkolben 38. Zur Symbolisierung der einseitigen Wirkung ist in den 3 ff der Schließdämpferkolben 38 wieder vereinfachend lediglich entsprechend abgeschrägt dargestellt. Die Kolbenstange 36 ist mit dem Supportschlitten 17 fest verbunden, dessen Position -wie bereits ausgeführt- aufgrund der exzentrischen Anlenkung der Treibstangen 23 an das feststehende Achsdorn-Mittelstück 4.2 ausschließlich von der Stellung des Toilettendeckels 3 abhängig ist. Somit wirkt der Schließdämpfer 35 auf den Toilettendeckel 3, und zwar dämpft er dessen Schließbewegung, denn dann bewegt sich der Supportschlitten 17 und ebenso der Schließdämpferkolben 38 im Bild nach unten, vgl. 7 und 3. Beim Öffnen des Toilettendeckels 3 übt der Schließdämpfer 35 zumindest nahezu keine Dämpfungskraft aus, allenfalls eine sehr geringe, hervorgerufen durch unvermeidliche Reibungs- und Strömungsverluste im Schließdämpfer 35.

In detail:

• It is a damper 35 (please refer 3rd ) is provided, which can be constructed in principle the same or similar to the damper already described 29 . In particular, the closing damper 35 a damper cylinder 37 have the im in the toilet lid 3rd trained bed 20th is fixed. A piston rod 36 carries a single-acting piston damper 38 . To symbolize the one-sided effect is in the 3rd ff the damper piston 38 again shown simply beveled. The piston rod 36 is with the support sled 17th firmly connected, whose position - as already stated - due to the eccentric linkage of the drive rods 23 to the fixed center arbor spine 4.2 exclusively from the position of the toilet lid 3rd is dependent. Thus, the closing damper works 35 on the toilet lid 3rd , and it dampens its closing movement, because then the support slide moves 17th and also the closing damper piston 38 in the picture below, cf. 7 and 3rd . When opening the toilet lid 3rd the damper practices 35 at least almost no damping force, at most a very low one, caused by inevitable friction and flow losses in the closing damper 35 .

In addition, the damper carries 29 in connection with the drag linkage 16 including drag hook 22 and the belt drive 10th to dampen the closing movement with: by lowering the toilet seat 2nd connected (back) rotation of the toilet seat bushing 7 , 7.1 including roll-off backdrop 9 the position of the belt linkage also becomes the closed starting position 11 to the toilet seat socket 7 , 7.1 by means of the belt connection pin 12 from its in 8 b shown position with the toilet seat open 2nd back into the radial, roughly opposite the pulley-fixed pulley 13.1 lying, in 8 a shown position with closed toilet seat 2nd transferred. The strap 11 of the belt drive 10th is then due to the rolling link 9 the free length of the belt 11 shortens and the idler 14 moves back to the lower end position. This is done by the tow linkage 16 the tow hook 22 retracted and pushes the damper cylinder 30th down (see 7 ), the degree of damping during the movement from top to bottom, as already explained, is less than the degree of damping during the opposite movement of the damper cylinder 30th from the bottom up

When the toilet lid closes 3rd This leads together with the toilet lid sockets 8th , 8.1 another rotation around the axis 4th off (vice versa as when opening). The connecting rods 23 shift due to their eccentric articulation on the fixed axis mandrel center piece 4.2 the support sled 17th in bed 20th from its upper end position in the picture down to its lower end position with the toilet lid closed 3rd .
This is also from the representations in the 7 and 3rd can be seen, in 7 strictly speaking, support sled 17th has already moved very slightly downwards from the upper end position, since the toilet seat and cover arrangement 2, 3 are already in the closing movement and no longer in the fully open position (see 7a) . In addition, the stop ring 32 already from the release hook 34 slightly lifted off.

Although due to the geometric design of the toilet seat 2nd and toilet lid 3rd the downward movement of the toilet lid 3rd no faster than that of the toilet seat 2nd because the toilet lid 3rd then lies on the toilet seat 2nd on. However, the toilet seat must also be prevented from lowering 2nd opposite the toilet lid 3rd advanced.
There is a coupling mechanism for this 57 provided the toilet lid 3rd and toilet seat 2nd mechanically couples, so that both can only lower together. The coupling mechanism 57 is in the 3rd and 4th drawn in as well as detailed in the 11a and 11b shown a section along the line B - B in the 3rd and 4th demonstrate. It shows 11a the conditions when the toilet seat and lid arrangement are closed 2nd , 3rd , corresponding 3rd and 11b the conditions with the toilet seat and lid arrangement 2, 3 open accordingly 4th .

The coupling mechanism 57 consists of one in the toilet lid 3rd with one end 58 clamped leaf spring element 60 . The other, free end 59 the leaf spring element is preferred, but not mandatory, with an attached end piece 64 provided, (see detailed illustration in 11a and 11b) . In the relaxed basic state of the leaf spring element 60 and with the same angular position of the toilet seat 2nd and toilet lid 3rd (as in 11 a shown), grips the free end 59 of the leaf spring element 60 with its attached end piece 64 into one in the toilet seat socket 7 , 7.1 trained lead 61 and couples the toilet seat with the procedure 2nd with the toilet lid 3rd so that the toilet seat 2nd opposite the toilet lid 3rd when closing the toilet seat and lid assembly 2nd , 3rd can't lead. Through the coupling mechanism 57 becomes the damping force of the closing damper 35 also on the toilet seat 2nd transfer.
The engagement surfaces are preferably of protrusion 61 and tail 64 , corresponding to each other, slightly beveled, as can be seen from the detailed illustrations.

The coupling mechanism 57 still has one on the axle mandrel 4.1 fastened, or with the axle mandrel 4.1 integral cam disc 62 with a cam 63 on. The cam 63 works with the tail 64 of the free end 59 of the leaf spring element 60 together and is designed and positioned so that the leaf spring element 60 when opening the toilet lid 3rd shortly before the approximately vertical, full opening angle is reached by the cam 63 is deflected from its relaxed basic state, as from 11b becomes clear. This will engage the free end 59 or the end piece 64 in the lead 61 and thus the coupling of the toilet seat 2nd with the toilet lid 3rd canceled.
Now is only a manual closing of the toilet seat 2nd possible, because that in the toilet lid 3rd clamped leaf spring element 60 stays through the cam 63 as long as deflected (which prevents coupling) as long as the toilet lid 3rd is in the open position, regardless of the position of the toilet seat 2nd .

When closing the toilet seat together 2nd and toilet lid 3rd slides the end piece 59 on the running cam track, the cam 63 gives the leaf spring element 60 shortly after leaving the approximately vertical, complete opening angle, so that it returns to its relaxed basic position, in which the free end 59 or the end piece 64 in the lead 61 the toilet seat socket 7 , 7.1 engages and so the toilet seat 2nd with the toilet lid 3rd couples again.

• Der Rückwerfer 39 dient der Auslösung der automatischen Schließbewegung der Toilettensitz- und -Deckelanordnung 2, 3 nach Benutzung der Toilette. Er arbeitet mit dem Lösehaken 34 und dem Lösehakengestänge 33 zusammen, siehe 3 und ist im Fuß des Toilettendeckels 3 auf Höhe des Achsdorn-Mittelstücks 4.2 angeordnet. Aus Übersichtsgründen ist er in den 3 ff selbst nicht dargestellt, es wird lediglich symbolisch (Verweis auf 9 im Kreis) mit dem Pfeil am Kreis auf die Anbindungsstelle des Lösehakengestänges 33 verwiesen.

The following is the structure and function of the rear light 39 based on 9 ad explains:

• The rear thrower 39 serves to trigger the automatic closing movement of the toilet seat and lid arrangement 2, 3 after using the toilet. He works with the release hook 34 and the release hook linkage 33 together, see 3rd and is in the foot of the toilet lid 3rd at the level of the center arbor spine 4.2 arranged. For reasons of clarity, it is in the 3rd ff itself is not shown, it is only symbolic (reference to 9 in a circle) with the arrow on the circle to the connection point of the release hook linkage 33 referred.

The rear thrower 39 itself is in the 9 ad detailed, its structure is based on 9a explained. The rear thrower 39 consists essentially of a lever tooth 41 by means of a between the two ends of the lever tooth 41 provided lever tooth axis 44 on the toilet lid 3rd is rotatably mounted. One end of the lever tooth 41 is the centerpin of the axle mandrel 4.2 facing and has a lever tooth tip 53 as well as a lever tooth flank 42 on that with the axle mandrel centerpiece 4.2 work together, in the middle of the axle mandrel 4.2 a bulge 40 with a bulge flank 43 is incorporated. At the other end of the lever tooth 41 is a lever tooth head 45 with a hole 46 trained in the one leg spring 47 engages with one end. The other end of the leg spring 47 is in a housing bore 56 in the toilet lid 3rd fixed on this. The turns of the leg spring 47 enclose a leg spring bolt 49 , which extends in its longitudinal extent beyond the area covered by the turns and with this free area into an elongated hole 50 engages, which on the release hook 34 opposite end of the release hook linkage 33 is formed transversely to the longitudinal axis.

The lever tooth 41 points to its in the starting position (toilet lid closed, 9a) the centerpin of the axle pin 4.2 Longitudinal side facing away, approximately in the middle, a lever tooth groove 48 on, and then to the hole 46 there, a lever tooth contact surface 54 . The entire arrangement is designed and coordinated so that in the open position of the toilet lid 3rd (please refer 9 c) the lever tooth groove 48 on one shoulder 52 of the axis mandrel center piece 4.2 , the lever tooth contact surface 54 on one in the toilet lid 3rd trained counter stop surface 55 and the lever tooth tip 53 on the bulge flank 43 opposite flank of the bulge 40 of the axis mandrel center piece 4.2 come to the plant.

The leg spring is in this position 47 cocked and locked in a stable position. Because the articulation points defining a toggle lever, the through the lever tooth axis 44 who have favourited Bore 46 and the housing bore 56 have just passed the dead center at which the above three points lie on a line: as from 9c visible, is through the hole 46 certain pivot point opposite the connecting line: lever tooth axis 44 - Housing bore 56 a little bit towards the lever tooth contact surface 54 moved there.

• Wird der Toilettendeckel 3 aus der in 9a gezeigten, geschlossenen Grundstellung angehoben, so bewegt sich der Hebelzahn 41 mit seiner Hebelzahnspitze 53 und der Hebelzahnflanke 42 in Richtung auf die Ausbuchtung 40 des Achsdorn-Mittelstücks 4.2 und die Hebelzahnflanke 42 kommt schließlich in Anlage an die Ausbuchtungsflanke 43, siehe 9 b. Die Hebelzahnflanke 42 gleitet auf der Ausbuchtungsflanke 43 ab, dreht dabei den Hebelzahn 41 um die Hebelzahnachse 44 und spannt bei dieser Bewegung die Schenkelfeder 47 bis sich diese schließlich bei geöffnetem Toilettendeckel 3 in der oben beschriebenen, in 9c gezeigten stabilen verriegelten Position befindet, wobei die Hebelzahnkehle 48 an der Schulter 52, die Hebelzahn-Anlagefläche 54 an der Gegenanschlagfläche 55 und die Hebelzahnspitze 53 an der der Ausbuchtungsflanke 43 gegenüberliegenden Flanke der Ausbuchtung 40 des Achsdorn-Mittelstücks 4.2 zur Anlage kommen. Dabei bewegt sich aus kinematischen Gründen der Schenkelfederbolzen 49 im Langloch 50 aus der in 9a dargestellten einen Endposition in die in 9c gezeigte andere Endposition des Langlochs 50.

The functional sequence of the rear light 39 results from the successive consideration of the 9 ad :

• Will the toilet lid 3rd from the in 9a shown, closed basic position raised, the lever tooth moves 41 with its lever tooth tip 53 and the lever tooth flank 42 towards the bulge 40 of the axis mandrel center piece 4.2 and the lever tooth flank 42 finally comes into contact with the bulge flank 43 , please refer 9 b . The lever tooth flank 42 slides on the bulge flank 43 turns the lever tooth 41 around the lever tooth axis 44 and tensions the leg spring during this movement 47 until they finally open when the toilet lid is open 3rd in the above described, in 9c shown stable locked position, the lever tooth groove 48 on the shoulder 52 , the lever tooth contact surface 54 on the counter stop surface 55 and the lever tooth tip 53 on the bulge flank 43 opposite flank of the bulge 40 of the axis mandrel center piece 4.2 come to the plant. The leg spring bolt moves for kinematic reasons 49 in the slot 50 from the in 9a represented an end position in the in 9c shown other end position of the elongated hole 50 .

The rear light is finally triggered, which, as already described, when the stop ring contacts 32 with the release hook 34 and easy pull on the release hook linkage 33 the case is (see 7 and 9 c) , it snaps through the hole 46 certain pivot point of the lever tooth 41 about the dead center and the leg spring 47 is released from the stable, locked position and the spring force can develop. The spring force causes the lever tooth to turn back 41 around the lever tooth axis 44 (in the opposite direction as when opening the toilet lid 3rd ), with the lever tooth groove 48 on the shoulder 52 of the fixed axis mandrel center piece 4.2 , later the lever tooth flank 42 on the bulge flank 43 supports and the toilet lid 3rd thereby slightly moved out of the vertical, open position, which is sufficient for the closing movement of the toilet lid 3rd to initiate, see 9 d , the toilet lid 3rd due to its larger diameter (compared to the inside diameter of the toilet seat) on the toilet seat 2nd rests and takes it with the closing movement.
The further joint closing movement then takes place through the gravity of the toilet lid 3rd and toilet seat 2nd .

• In der ersten Phase der Benutzung wird die Toilettensitz- und Deckelanordnung 2, 3 gemeinsam händisch aus der geschlossenen Stellung (3) angehoben und in die in 4 dargestellte geöffnete Stellung gebracht. Dabei wird der Supportschlitten 17 mittels der Treibstangen 23 in die im Bild obere Stellung überführt und die zwischen Supportschlitten 17 und der ihm zugewandten Stirnseite des Dämpferzylinders 30 eingespannte, zweite Schraubendruckfeder 28 gespannt. Gleichzeitig wird über den Riementrieb 10 im Zusammenwirken mit der ersten Schraubendruckfeder 18 das Schlepphakengestänge 16 samt Schlepphaken 22 im Bild nach oben verschoben, der Schlepphaken 22 gibt den Dämpferzylinder 30 frei. Dieser bewegt sich nun unter der Wirkung der zweiten Schraubendruckfeder 28 sehr stark gedämpft, d.h. sehr langsam nach oben.

Weiter wird der Schließdämpferkolben 38 des Schließdämpfers 35 im Schließdämpferzylinder 37 ungedämpft nach oben im Bild verschoben.
Die Schenkelfeder 47 des Rückwerfers 39 wird (wie zuvor bereits detailliert beschrieben) gespannt und schließlich in die stabile verriegelte Position überführt.The detailed functional sequence of the actuating device when carrying out the method according to claim 1 will now be explained below:

• In the first phase of use, the toilet seat and lid assembly 2nd , 3rd together by hand from the closed position ( 3rd ) raised and into the in 4th brought open position shown. The support sled is used 17th by means of the drive rods 23 transferred to the upper position in the picture and between support slides 17th and the face of the damper cylinder facing him 30th clamped, second helical compression spring 28 curious; excited. At the same time, the belt drive 10th in cooperation with the first helical compression spring 18th the drag linkage 16 including drag hook 22 in the picture shifted up, the tow hook 22 gives the damper cylinder 30th free. This now moves under the action of the second helical compression spring 28 very strongly damped, ie very slowly upwards.

The damper piston continues 38 of the closing damper 35 in the damper cylinder 37 moved undamped upwards in the picture.
The leg spring 47 of the retractor 39 is tensioned (as already described in detail above) and finally transferred to the stable locked position.

Toilet seat 2nd and toilet lid 3rd are until shortly before the coupling mechanism opens completely 57 coupled with each other, however, are decoupled towards the end of the opening movement because of the cam 63 the engagement of the leaf spring element 60 (or the end piece 64 ) in the lead.

In the so-called "first case", in which the toilet is to be used while standing, the toilet seat remains 2nd and toilet lid 3rd so in the open position until after a few minutes (= expiry of the specified time) the damper cylinder 30th , which acts here as a (hydraulic) timer, if it has moved upwards (see 3rd and 7 ) that the stop ring 32 the release hook 34 touched and pulls something up. This will make the rear light 39 triggered as described and initiated the automatic closing movement of the toilet seat and lid assembly 2, 3. Shortly after leaving the fully open position of the toilet seat 2nd and toilet lid 3rd gives the cam 63 of the coupling mechanism 57 the leaf spring element 60 free again, the end piece 64 reaches back into the lead 61 and couples toilet seat 2nd and toilet lid 3rd .
The common closing movement of the toilet seat and lid arrangement thus coupled 2nd , 3rd is primarily due to the effective closing damper in this direction 35 , but also through the damper 29 in connection with the drag linkage 16 including drag hook 22 and belt drive 10th subdued. The individual components of the actuator are again in the described starting position according to. 3rd returned.

In the so-called “second case”, in which the toilet is to be used while sitting, the open position becomes the toilet seat 2nd and toilet lid 3rd (together with corresponding positions of the various components of the actuating device according to 4th and associated description parts), only the toilet seat 2nd manually lowered again into the closed position acc. 5 and held in this position by the toilet user throughout the sedentary use of the toilet. Lowering the toilet seat only 2nd alone is made possible because of the cam 63 in the open position of the toilet lid 3rd its coupling with the toilet seat 2nd as described.
The support sled 17th remains only when closing the toilet seat 2nd in its upper position in the picture, because the position of the support slide 17th is only from the position of the toilet lid 3rd dependent, which remains open.
By lowering the toilet seat 2nd connected rotation of the toilet seat bushings 7 , 7.1 including roll-off backdrop (s) 9 the belt drive pulls 10th over the drag linkage 16 the tow hook 22 and presses the damper cylinder 30th , already from the opening of the toilet seat and lid arrangement 2nd , 3rd started the slow upward movement again and holds it down as long as the toilet seat is in the closed (lowered) position. This prevents the stop ring 32 with the release hook 34 come into contact and the (cocked) rear light 39 can trigger. So the toilet lid 3rd kept stable in the open position during the entire sitting use of the toilet.
The first helical compression spring 18th and the second helical compression spring 28 are completely excited, see 5 .

If the toilet user gets up in the so-called “second case” after having finished using the toilet, he gives up the toilet seat 2nd free, this is automatically due to the accumulating forces on the damper cylinder 30th acting second helical compression spring 28 and the one on the tow bar 16 acting first compression spring 18th raised from the closed (lowered) position and moves dampened up to the open position, as already described in detail.

With this upward movement the stop ring comes 32 of the damper cylinder 30th finally with the toilet seat standing approximately vertically 2nd with the release hook 34 touches and pulls it slightly upwards, so the rear light 39 triggered the closing of the toilet lid 3rd initiates, which in turn the toilet seat 2nd takes away (s. 7 and 7a) .

Shortly after leaving the approximately vertical, full opening angle of the toilet seat and lid arrangement 2nd , 3rd gives the cam 63 of the coupling mechanism 57 the leaf spring element 60 free again, so this the toilet seat 2nd with the toilet lid 3rd couples again and this ensures that the toilet seat 2nd without leading together with the toilet lid 3rd lowers (cf. 11a and 11b in connection with the detailed explanatory description).

The automatic, common lowering of the toilet seat 2nd and toilet lid 3rd in the closed (starting) position is primarily damped by the closing damper 35 that over the support sled 17th on the toilet lid 3rd works in cooperation with the coupling mechanism 57 that the toilet lid 3rd with the toilet seat 2nd couples, so that the damping force of the closing damper 35 also on the toilet seat 2nd unfolded. The damper too 29 contributes - but to a lesser extent to dampen the closing movement of the toilet seat and lid arrangement 2nd , 3rd at.
