Definitions

  • the invention relates to a method for actuating a toilet seat and lid arrangement according to the preamble of claim 1 and to a toilet seat and lid arrangement with an actuation device according to claim 2.
  • a method according to the preamble of claim 1 is from WO 01/93737 A1 known.
  • the toilet seat and toilet lid remain in the position in which they were left after use, unless they are closed again manually by the user.
  • at least the toilet lid can remain in the open position.
  • a toilet that is not closed is often perceived as unaesthetic.
  • the toilet is left with the lid open but the toilet seat lowered and a following user urinates standing up without first lifting the toilet seat, which can lead to unwanted drips on it. It can also happen that after cleaning the toilet bowl, when you put the toilet brush back and move it over the edge of the toilet, drops fall from the toilet brush onto the toilet seat if it was not opened manually for cleaning after using the toilet.
  • the DE 202 16 128 U1 discloses a toilet seat and lid assembly having a Opening device has such that the toilet lid and / or the toilet seat automatically pivots into the open position in response to a trigger signal (e.g. a light tap should be sufficient) in order to avoid that the toilet seat and lid assembly has to be folded up manually.
  • a trigger signal e.g. a light tap should be sufficient
  • the automatic opening of the toilet seat and lid assembly can be effected with the force of a spring arranged in the hinge area and mounted on a support rod. How the toilet seat and lid assembly should be returned to the closed position after using the toilet remains an open question.
  • 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 while sitting after manual opening and/or after the filling process of the cistern has ended within a certain, freely selectable period of time.
  • a toilet in particular an aircraft toilet, is known, each with a drive device for automatically moving the lid and the toilet seat between the closed and open positions.
  • the two electric motor drive devices can be operated independently of one another and are controlled by the user via an operating device.
  • the US 9,532,686 B1 discloses a toilet seat and lid assembly with an actuator, wherein the toilet lid has a cavity for receiving the components of the actuator.
  • the timer is interrupted and the toilet lid is blocked in the open position as long as a certain minimum pressing force (e.g. by a sitting person) is exerted on the toilet seat.
  • a certain minimum pressing force e.g. by a sitting person
  • the interruption of the timer sequence is canceled, the timer continues to run, and when it has expired, it releases the toilet lid and initiates its automatic closing.
  • the device is designed around the common axis of rotation of the toilet lid and seat.
  • the invention is based on the object of avoiding the disadvantages described above and of specifying a method in which a high standard of hygiene is ensured even without the toilet user's intervention. Furthermore, an actuation device for a toilet seat and lid arrangement is to be presented, with which such hygienic actuation of the toilet seat and lid arrangement is possible without an external power connection.
  • the toilet seat and lid in a first phase (due to suitable design training) can only be brought into the open position together by hand means that the toilet can only be used while standing (so-called first case) when the toilet seat is open .
  • first case a subsequent user can only use the toilet while standing when the toilet seat is open.
  • the toilet seat and lid automatically return to the closed position together after a predetermined time has elapsed after opening position can be lowered.
  • the specified time must be based on the usual duration of use plus a time surcharge.
  • the lifting speed of the toilet seat can be provided to be variable via the opening angle (smaller lifting speed in the area of larger opening angles) and must be coordinated with the usual duration of a cleaning process, at least in the area of larger opening angles.
  • the actuating device according to the invention has a purely mechanical-hydraulic structure and all components are arranged in a closed cavity of the toilet lid, neither an external energy and/or control connection including cable or pipe connections is required, nor is it necessary to have any components somewhere on the outside of the toilet seat - and lid arrangement.
  • the toilet seat and lid assembly has largely smooth surfaces that are easy to clean and keep hygienically clean.
  • FIGS 1 ac and 2a-f show a toilet, consisting of a toilet bowl 1, toilet seat 2 and toilet lid 3.
  • the toilet seat 2 and the toilet lid 3 are rotatably articulated about the axis 4 on a common axle mandrel 4.1.
  • the axle mandrel 4.1 in turn opens at both ends into lateral holding devices 5, which are attached to the toilet bowl 1 directly or, if necessary, with the interposition of an adapter to adapt to the hole spacing of the toilet bowl 1.
  • the toilet seat and lid arrangement 2, 3 is structurally designed in such a way that the toilet seat 2 and toilet lid 3 can only be lifted manually together from the closed position.
  • the toilet lid 3 is constructed in such a way that it has no possibility of intervention and has a smaller circumference laterally and towards the front than the toilet seat 2. In the closed position, the toilet lid 3 rests flush on the toilet seat 2.
  • a manual intervention for opening can only take place under the toilet seat 2 provided with support elements 6, the support elements 6 creating a vertical distance between the toilet bowl 1 and the toilet seat 2, which enables manual intervention.
  • toilet seat 2 and toilet lid 3 are put together, after reaching under the toilet seat 2 (see detailed illustration in Fig. 1a ) lifted manually and from the closed position ( Fig. 1a ) into the in Fig. 1b shown open position.
  • This movement should be done by the two arrows in Fig. 1b be represented symbolically.
  • One arrow stands for the movement of the toilet lid 3, the other for the movement of the toilet seat 2. This also applies analogously to the arrow representations in the other partial figures of Fig. 1 and 2 .
  • the toilet lid 3 and toilet seat 2 initially remain in this open position.
  • the toilet can be used while standing, without the toilet seat 2 being contaminated by splashes when urinating.
  • the toilet lid 3 and the toilet seat 2 are automatically brought back into the closed position together without any action on the part of the user by an installed and/or attached actuating device (not yet shown here), as in Fig. 1c shown.
  • the toilet is ready for the next user.
  • the duration of the above-mentioned time in which the toilet lid 3 and toilet seat 2 are kept open can, for example, be coordinated with the usual duration of standing toilet use plus a "safety allowance" and can be easily determined through experiments. It can, for example, be between 2 and 5 minutes.
  • the toilet seat and lid assembly 2, 3 can remain in this open position for a specific time, during which it is possible to clean the toilet bowl 1 with a toilet brush. After the determinable time has elapsed, the toilet lid 3 and toilet seat 2 are automatically brought back into the closed position together without the user's intervention by the installed and/or attached actuating device (not shown here), as in Fig. 2f shown. The toilet is ready for the next user.
  • the toilet seat and lid arrangement 2, 3 instead of leaving the toilet seat and lid arrangement 2, 3 in the open position for cleaning the toilet bowl 1, provision can also be made to specifically reduce the speed of the upward movement of the toilet seat 2 to such an extent once a larger angle has been reached that cleaning can already be completed can be carried out during the slow upward movement of the toilet seat 2. It is then no longer necessary for the toilet seat and lid arrangement 2, 3 to remain in the open position; rather, after reaching the fully open position and touching the toilet seat 2 and toilet lid 3 ( Fig. 2e ) go into the joint closing movement without any further pause, which begins when the in Fig. 2f closed position shown ends.
  • the toilet seat 2 Because the toilet seat 2 is lifted off the toilet bowl 3 during the cleaning process and is approximately vertical (or at least has a large angle according to the above alternative), the toilet seat 2 cannot become dirty due to any water dripping or splashing from the brush .
  • the method described above for actuating the toilet seat and lid assembly 2, 3 can in principle be carried out using various built-in or attached actuation devices, such as electrically using electromagnetic, electromotive, pneumatic or hydraulic actuation devices in conjunction with an electrical or electronic control .
  • actuation devices such as electrically using electromagnetic, electromotive, pneumatic or hydraulic actuation devices in conjunction with an electrical or electronic control .
  • a purely pneumatic actuation device is also conceivable.
  • FIGS 3 - 7 The basic structure of a mechanical-hydraulic actuation device is shown. This is installed within a cavity of the toilet lid 3, for which purpose the toilet lid 3 is constructed in two parts with at least one curved part, for example the toilet lid upper part 3.1. Alternatively, but not shown here, the toilet lid 3 can also be provided in one piece with a front insertion 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.
  • Figure 3 shows the view with the toilet seat and lid assembly 2, 3 closed as seen from the toilet bowl 1, as in Fig. 3a indicated by the arrow.
  • a toilet seat bushing 7 on the outside right and another toilet seat bushing 7.1 on the outside left can be rotated between the two holding devices 5 stored.
  • the toilet seat 2, of which only parts with two support elements 6 are shown here for reasons of illustration, is rigidly connected to both toilet seat bushings 7, 7.1, so that when the toilet seat 2 is raised and lowered, they carry out a rotational movement relative to the fixed axle mandrel 4.1 about the axis 4 .
  • a fixed axle mandrel center piece 4.2 is provided between the two toilet lid sockets 8, 8.1. It can be designed in one piece with the axle mandrel 4.1, or it can be designed as a separate component and rigidly connected to the axle mandrel 4.1. Since the axle mandrel center piece 4.2 has a larger cross section than the areas of the axle mandrel 4.1 encompassed by the toilet seat bushings 7, 7.1 and the toilet lid bushings 8, 8.1, there is a stop against axial displacement of the toilet seat 2 and toilet lid 3. On the axle mandrel center piece 4.2 Two drive rods 23 are articulated radially to the axis 4, namely by means of two axle-side fastening bolts 25, which are arranged parallel and eccentric to the axis 4.
  • FIG. 3 shows the link on the left in the picture in a breakout from the axle mandrel center piece 4.2, the link on the right in the picture is shown in dashed lines because it is hidden.
  • the other ends of the drive rods 23 are fastened by means of support-side fastening bolts 24 to a substantially cuboid support carriage 17, which is arranged to be longitudinally displaceable in a bed 20 formed in the toilet lid upper part 3.1.

  • Figure 10 b shows the position with the toilet lid 3 open accordingly Figure 4 (but also 5 and 6).
  • the axle mandrel center piece 4.2 has a milling 4.3 for receiving the drive rod 23.

  • the drive rod 23 is also rotatably attached to the support carriage 17 by means of the support-side fastening bolt 24.
  • Figure 10a the support carriage 17 is retracted into its lower end position in the closed position of the toilet lid 3, while in the open position of the toilet lid 3 ( Figure 10b ) is extended into its upper end position due to the eccentric articulation of the drive rod 23 on the axle mandrel center piece 4.2 to the axis 4.
  • a rolling gate 9 is formed on part of its circumference, to which a closed, endless belt 11 forming a belt drive 10 is articulated by means of a belt connecting pin 12.

  • Figure 5 corresponds with Figure 8c (Conditions with the toilet lid 3 open and the toilet seat 2 lowered as per. Figure 5a ).
  • the belt 11 is fixed to the toilet seat bushing 7 with the belt connection pin 12 and wraps around a partial circle of the toilet seat bushing 7, resting on the rolling link 9; continues to wrap around an axle-fixed deflection roller 13.1, (in Fig. 3 not visible because it is covered by the axle mandrel 4.1 and the toilet seat bushing 7), which is mounted on a projection of the axle mandrel 4.1 (alternatively: on a projection of the axle mandrel center piece 4.2).
  • the belt 11 is further secured via two deflection rollers 13 (which are fixed to the toilet lid).
  • Fig.8a guided on the bed 20 formed in the toilet lid upper part 3.1 ( Fig.3 ) are attached and finally wraps around a support roller 14, which is mounted on a fork head 15 connected to a longitudinally displaceable tow hook linkage 16.
  • the tow hook linkage 16 penetrates with play the support carriage 17, which is guided longitudinally displaceably in the bed 20, on which a first helical compression spring 18, which includes the tow hook linkage 16, is supported at one end.
  • the other end of the first helical compression spring 18 is mounted on a spring plate 19 formed on the tow hook linkage 16, so that the first helical compression spring 18 is compressed or relaxed during relative movements between the tow hook linkage 16 and the support carriage 17.
  • the upper part of the towing hook linkage 16 in the picture is guided with play through a passage 21 formed in the bed 20 ( Figures 3ff) and has one at its end Tow hook 22, which forms a stop for a housing (damper cylinder 30) of a hydraulic damper 29, which is part of a spring-damper arrangement 28, 29, which will be described in more detail later.
  • Damper cylinder 30 and tow hook 22 are designed in such a way that the damper cylinder 30 can be acted upon by the tow hook 22 against the spring force of a second helical compression spring 28 clamped between the support carriage 17 and the end face of the damper cylinder 30 facing it.
  • the position of the towing hook 22 is only dependent on the position of the toilet seat 2.
  • the toilet seat 2 When the toilet seat 2 is in the closed position, it is in its lower end position near the bushing 21, see Figure 3 , with the toilet seat 2 open in its upper end position, away from the bushing 21, see Figure 4 .
  • the first helical compression spring 18 is relaxed, since the support carriage 17 is in its lower end position when the toilet lid 3 is closed, just as the tow hook 22 together with the tow hook linkage 16 and the spring plate 19 are in their lower end position when the toilet seat 2 is closed (lowered).
  • the structural design of the rolling backdrop 9 can influence the movement parameters of the toilet seat 2 during its automatic movements (not manual movements).
  • the cross section of the rolling backdrop 9 is shown in simplified form as increasing in circumference and exaggerated for clarity.
  • the first helical compression spring 18 is maximally tensioned, because when the toilet lid 3 is open, the support carriage 17 is in its upper end position and the tow hook 22 together with the tow hook linkage 16 and spring plate 19 is in the lower end position when the toilet seat 2 is closed (lowered).
  • the spring-damper arrangement 28, 29 is dimensioned and coordinated so that the movement of the damper cylinder 30 upwards (compression stage) is very slow and takes a few minutes from its lower end position to its upper end position, for example 5 minutes. But 2 minutes or times in between are also conceivable. During this entire time, the toilet lid 3 and toilet seat 2 are already in their open position after being opened manually and the toilet can be used.
  • a stop ring 32 is formed on its circumference (see Fig. Fig. 3 ), which interacts with a release hook 34. If, during the (strongly damped) upward movement of the damper cylinder 30, the stop ring 32 comes into contact with the release hook 34 and pulls it slightly upwards, this triggers a return mechanism 39 via a release hook linkage 33 connected to the release hook 34, which causes the toilet lid 3 to close (and thus also the toilet seat 2). The exact structure and mode of operation of this throwback 39 will be discussed later in connection with Figure 9 described in detail.
  • the function of the towing hook 22 must be discussed again, in connection with the so-called "second case” of toilet use described above, in which, after manually lowering the toilet seat 2, the toilet should be used while sitting, with the toilet lid 3 of course must remain in the open position for as long as possible.
  • the latter is ensured with the help of the tow hook 22:
  • opened toilet lid 3 and closed (lowered) toilet seat 2 is in the Figures 5 and 8c shown and has already been described above:
  • the support carriage 17 is then in the upper end position (because of the open toilet lid 3), the towing hook 22 together with the towing hook linkage 16 and spring plate 19 is in the lower end position and is also in the lower end position by the person sitting on the toilet seat 2 kept there.
  • the second helical compression spring 28, like the first helical compression spring 18, is fully tensioned.
  • the damper cylinder 30 Through the in the lower end position Contact with the upper end face of the damper cylinder 30 located tow hook 22, in this position of the toilet seat 2 and toilet lid 3, the damper cylinder 30 is prevented from moving upwards under the action of the second helical compression spring 28 as long as the toilet seat 2 is in the closed ( lowered) position. Consequently, the stop ring 32 of the damper cylinder 30 cannot come into contact with the release hook 34 and trigger the throwback 39 which initiates the closing of the toilet lid 3. The toilet lid 3 thus remains safely in the open position.
  • the user If the user stands up after using the toilet while sitting and releases the toilet seat 2, it automatically moves up from the closed (lowered) position in a damped manner due to the cumulative forces of the first helical compression spring 18 and the second helical compression spring 28.
  • This situation with the toilet seat 2 already slightly raised is in the Figures 6 and 6a shown, where in Figure 6a the dashed arrow shows the direction of movement of the toilet seat 2, the solid arrow again shows the direction of view.
  • the first helical compression spring 18 and the second helical compression spring 28 are each dimensioned such that the force of one of the two springs 18, 28 alone is not large enough to lift the toilet seat 2.
  • the relaxing second helical compression spring 28 acts upwards in the picture via the damper cylinder 30 on the towing hook 22, which acts on the towing hook linkage 16, supported by the also relaxing first helical compression spring 18.
  • the summed total force of both springs 18, 28 acts via the belt drive 10, the belt connection pin 12 and the rolling link 9 onto the toilet seat socket 7, which lifts the toilet seat 2 attached to it. Due to the damping effect of the damper 29 on the relaxation force of the second helical compression spring 28, the opening movement of the toilet seat 2 occurs slowly.
  • a closing damper 35 (see Figure 3 ) is provided, which in principle can have the same or similar structure as the damper 29 already described.
  • the closing damper 35 can have a closing damper cylinder 37, which is fixed in the bed 20 formed in the toilet lid 3.
  • a piston rod 36 carries a one-sided closing damper piston 38. To symbolize the one-sided effect is in the Figures 3 ff the closing damper piston 38 is again simply shown slanted accordingly.
  • the piston rod 36 is firmly connected to the support carriage 17, the position of which - as already stated - depends exclusively on the position of the toilet lid 3 due to the eccentric articulation of the drive rods 23 to the fixed axle mandrel center piece 4.2.
  • the closing damper 35 thus acts on the toilet lid 3, namely it dampens its closing movement, because then the support carriage 17 and also the closing damper piston 38 move downwards in the picture, cf. Figures 7 and 3 .
  • the closing damper 35 exerts at least almost no damping force, at most a very small one, caused by unavoidable friction and flow losses in the closing damper 35.
  • damper 29 in conjunction with the tow hook linkage 16 together with the tow hook 22 and the belt drive 10 contributes to the damping of the closing movement: through the (back) rotation of the toilet seat bushing 7, 7.1 together with the rolling gate 9 into the closed position, which is associated with the lowering of the toilet seat 2
  • the location of the articulation of the belt 11 to the toilet seat bushing 7, 7.1 by means of the belt connection pin 12 is also changed from its in Figure 8 b position shown with the toilet seat 2 open again in the position lying radially approximately opposite the deflection roller 13.1 fixed to the axle mandrel, in Figure 8 a position shown with the toilet seat 2 closed.
  • the belt 11 of the belt drive 10 then rests accordingly on the rolling link 9, the free length of the belt 11 is shortened and the support roller 14 moves back into the lower end position.
  • the tow hook 22 is pulled in by the tow hook linkage 16 and presses the damper cylinder 30 downwards (see Figure 7 ), whereby 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 30 from bottom to top.
  • a coupling mechanism 57 is provided, which mechanically couples the toilet lid 3 and toilet seat 2, so that both can only lower together.
  • the coupling mechanism 57 is in the Figures 3 and 4 marked, as well as detailed in the Figures 11a and 11b shown, which is a cut along the line B - B in the Figures 3 and 4 show.

  • the support carriage 17 is moved into the upper position in the picture by means of the drive rods 23 and the second helical compression spring 28 clamped between the support carriage 17 and the end face of the damper cylinder 30 facing it is tensioned.
  • the towing hook linkage 16 together with the towing hook 22 is moved upwards in the picture via the belt drive 10 in cooperation with the first helical compression spring 18, the towing hook 22 releases the damper cylinder 30.
  • Toilet seat 2 and toilet lid 3 are coupled to one another until shortly before they are fully opened by the coupling mechanism 57, but are decoupled towards the end of the opening movement because the cam 63 has canceled the engagement of the leaf spring element 60 (or the end piece 64) in the projection.
  • the common closing movement of the toilet seat and lid arrangement 2, 3 coupled in this way is primarily due to the closing damper acting in this direction 35, but also dampened by the damper 29 in conjunction with the tow hook linkage 16 including tow hook 22 and belt drive 10.
  • the individual components of the actuating device are returned to the starting position described. Fig. 3 returned.
  • the automatic, joint lowering of the toilet seat 2 and toilet lid 3 into the closed (starting) position is primarily dampened by the closing damper 35, which acts on the toilet lid 3 via the support carriage 17, in cooperation with the coupling mechanism 57, which holds the toilet lid 3 coupled to the toilet seat 2, so that the damping force of the closing damper 35 also develops on the toilet seat 2.
  • the damper 29 also contributes - albeit to a lesser extent - to dampening the closing movement of the toilet seat and lid arrangement 2, 3.
