After use is finished, the button valve 6 is demolded and the cleaning process begins as described above. , whereby the sanitary cover 17 is drawn into the toilet bowl 1 by cleaning. and then removed. The same signal from button valve 6 also turns on the lifting device for toilet seat 5. can. In this case, pressure is applied to the operating cylinder 13 via the pipe 33, which The piston rod 30 is drawn into the operating cylinder 13 by the The shaft 12 is then rotated counterclockwise.

The toilet seat 5 is thereby swung into the front of the top 20 or into the storage chamber 18. .

This starts a new cycle.

Next, the sanitary cover 17 is automatically taken out from the storage chamber 18 in the upper place 20. and how to tighten and fix the sanitary cover 17 to the toilet seat 5. I will clarify.

In FIG. 3, a hygienic cover 17 for fixing the sanitary cover 17 to the toilet seat 5 is placed at the front upper end of the toilet seat 5. A clamping device or a suction device or another mechanism 39 is arranged. Figure 3 , the toilet seat 5 consists of two shells 44, 45 forming an internal chamber 46 between them. It has become. The upper shell 44 on the user side has a gap 41 when tightened, and this gap A clamping body 40 is swingably disposed within the clamping body 41 . Tighten on one side of gap 41 A stopper 42 is arranged.

In this case via the wire cable 47 or (alternatively) via the operating cylinder The arm 49, which is swingably supported by the bearing 48, is moved in the direction of the arrow 50 through the activated. The pressing element 51 is in contact with the swingable free part of the body 40 .

In this case, the body 40 is supported in the bearing 53 within the gap 41. There is.

By actuating the wire cable 47, the pressing element 51 is moved as shown in the arrow 50, and at the same time the body 40 is tightened clockwise around the bearing 53. The sanitary cover 1 is swiveling and is thus arranged in a stack in the storage chamber 18 Grab the paper at the front of number 7 with a friction bond.

The stack is held in the storage chamber 18 via a holder 43 (not shown in detail). It is.

The front paper of the sanitary cover 17 is tightened while forming a horizontal crease within the gap. It is pressed against the upper part 42.

This ensures that the sanitary cover 17 is held in front of the toilet seat 5. Now the toilet seat As soon as the sanitary cover 17 is swung in the direction of the arrow 19 in FIG. It is torn off from the holder 43 and carried away by the rocking movement of the toilet seat 5. in this case The central washing piece 11 mentioned above is inserted into the slit provided on the upper side of the inner lid 8. It is located in

As can be seen in FIG. 1, the central washout piece 11 is located behind the inner lid 8, and as shown in FIG. The remaining circumferential portion of the sanitary cover 17 is inserted into the slit 9 and covers the toilet seat itself. The portions are arranged outside the inner M8 and within the storage chamber 18.

In order to facilitate the action of the clamping device 39, in the rear region of the receiving chamber 18 one side is provided. A suppressing plate 54 is arranged which can swing and is biased by spring pressure. This pressing plate 54 is A stack of raw covers 17 is pressed against a clamping device 39.

There are various systems mentioned above that fully automate all tasks when using the toilet. can be changed to

Instead of the above-mentioned pressure water circuit for controlling the operating cylinder 13.28, a separate Pressure oil cylinders supplied from the pressure oil circuit can also be used. The pressure oil circuit is connected via a pressure booster. It is separated from the water circuit of the water network and is subjected to higher pressure than the tap water pressure.

Instead of the linear-motion actuating cylinders 13.28 mentioned above, rotary-motion cylinders can also be used. Available.

Of course, instead of the above-mentioned spring to reduce the weight of the toilet seat 5, a gas pressure spring can also be used. Can be used.

Next, the lifting drive in the form of a hydraulic operating device will be explained in detail.

The drive is carried out via a hydraulic cylinder driven by the water pipe network. Therefore, no special driving source is required. For single-acting drives, special protective measures must be taken. Electrical lines must be laid. Driven by pressure oil Although this is possible in principle, there is a problem in that the pressure oil causes contamination. Originally The drive system according to the invention, which is based on the pressure of the existing water pipe network, uses a special energy No introduction of energy is necessary and no problems arise, particularly with respect to dirt and integrity.

Here, the purpose of the present invention is to maintain this principle while providing a user with a significant benefit. The objective is to provide a practical structural method that simplifies new operations. .

For this purpose, the operating rod is formed as a piston rod and has a rack part, This rack part is connected to the second gear via a bushing that can swing within the dead swing angle range. This is achieved by meshing with the mating first gear.

The rack portion is either part of the piston rod or an extension of the piston rod. It is formed as. The first gear rotates by a predetermined angle, for example 30° to 40°. Only after the toilet seat is oscillate. During rocking motion in the dead rocking angle range, as described above, The sanitary cover is tightened to the upper toilet seat edge, followed by the drive shaft, which Therefore, the toilet seat is lowered.

In order to bring the rack part into good contact with the first gear, the contact is spring biased. Advantageously, this is carried out via a pressure piece or a roller.

Furthermore, it is advantageous if a spring, preferably a gas spring, is connected in parallel to the hydraulic cylinder. . This spring returns the toilet seat and other components to their starting position after use. The spring is During the rocking movement, it is correspondingly tensioned via a hydraulic cylinder.

Furthermore, the toilet seat is fixedly connected to the drive shaft for the rocking mechanism, and the drive mechanism is connected to the drive shaft. It is advantageous if an operating pin cooperating with the cross switch is connected. Predetermined rotation range All continuing work sequences are controlled via microswitches activated in the controlled.

In this regard, it is useful if the toilet seat has a holding position just before the activation of the microswitch. It is advantageous. The toilet seat will only swing fully downwards when the user sits on it. The microswitch is actuated and other actions are initiated as described below. .

In FIG. 4, the toilet seat 61 is shown in a raised position. In that case, the toilet A lid 63 is arranged over the toilet bowl 68 (not shown in detail), in which a flushing tank is located, among other things. 64 is fixed.

Since the lid is somewhat larger than the toilet seat, the toilet seat edge 62 lies within the recess 65 in the lid. Concave Sanitary covers 66 stacked on top of each other in a pack-like manner are fixed in the area 65. The sanitary covers are adapted to the shape of the toilet Ji61, each having an upper opening. There is. A retaining bolt 98 is inserted into the upper opening of the sanitary cover. sanitary cover is tightened against the raised toilet seat by an elastic pressing plate 99. on the toilet seat There is a tightening mechanism (not shown in detail), which is always present on the sanitary cover stack. Peel off the paper at the front of the toilet seat and grab it as it swings into the lowered position. .

The bearing side end of the toilet seat 61 is firmly connected to a drive shaft 69. Connection with this drive shaft In this case, various structural methods can be considered. As the first structural method, entrainment 70 is shown. This entraining bin 70 is firmly connected to the drive shaft 69 and is connected to the toilet seat 69. 1 into a corresponding bearing recess.

The drive shaft and toilet seat 61 can also be coupled in other ways.

In connection with FIG. 12, the rear end of the sanitary cover 66 is tightened by a lever 72. The lever 72 is firmly connected to the drive shaft 73, and this tightening is performed when the lever 72 is firmly connected to the drive shaft 73. is shown supported within space 80 along with another drive mechanism. The tightening lever 72 has a front tightening head 74, which is in the tightening position (Fig. 12). ), tighten the rear end of the sanitary cover within the recess 174 in the toilet seat 61. Ru.

As a result, the tightening on the toilet seat edge 62 is tightened at the upper end of the sanitary cover 66 via the mechanism. is fixed, and the lever 72 tightens the rear edge of the sanitary cover to the toilet seat 61. This ensures that the sanitary cover is securely fixed.

From FIG. 5 and FIG. 7, the drive for swinging the toilet seat and the swinging drive of the drive shaft 69 The movement mechanism can be understood in more detail.

In this case, the entire drive mechanism is arranged within a space 80 (see FIG. 8). this A space 80 protrudes from the rear housing portion approximately in the center, and extends parallel to each other on the sides. It is formed by two cross beams 67 extending at a distance.

This space is penetrated by various shafts, in particular the drive shaft 69 and the further drive shaft 73.

Inside this space 80 is a piston with a lower piston rod 85 in the area of the cross beam 81. A hydraulic cylinder 82 with a ton 83 is attached. This hydraulic cylinder Inside is a spring 8 that biases and holds the piston 83 in the lifted position. 4 is placed.

In this case, the target is a single-acting cylinder with an upper pressure chamber 175 to which pressure water is supplied. It is said that

Piston rod 85 is coupled to rack 86, in which case piston rod and Provision is made that the rack forms the only threaded part. The rack 86 has external teeth. The external teeth mesh with the teeth of a gear 92, and the gear 92 is firmly supported on the intermediate shaft 71. held.

In order to ensure sufficient pressing force of the rack on the gear 92, the gear 92 and the intermediate shaft 7 A pressing piece 87 biased by a spring is provided on the opposite side to 1. This pressure The piece rests against the opposite side of the rack 86 by a spring 88. The pressing piece 87 is It is movably held by a holding body 89 that is fixed to the ring.

By energizing the pressure chamber 175 of the hydraulic cylinder 83, the piston 83 moves its Rack 86 is moved downward in the direction of arrow 90, with gear 92 moving downward in the direction of arrow 91. rotated in the direction

This gear 92 meshes with a second gear 93 that is rigidly connected to the drive shaft 69. There is. In this case, the connection is made via a bushing 94 that can swing within the dead swing angle. (see Fig. 11), so after the gear 93 has rotated by an angle of, for example, 35 The drive shaft 69 is activated only after the bush is taken away and the dead swing angle is exceeded. is taken away.

This procedure involves first tightening the sanitary cover to the upper toilet seat edge 62 within the range of the dead rocking angle. is fixed, and then only by further rocking of the bushing 94 does the drive shaft 69 is carried away, which causes the toilet seat to swing clockwise to the lowered position. It means.

Note that tightening is done by the drive shaft 73 of the lever 72, and tightening is done by moving the lever 72 to its oscillated output. It is shown to have a return spring 95 which serves to return it to the firing position.

5 to 8 further show a bell-shaped lifting body 7 for activating the cleaning of the cleaning tank 64. 6 is also shown biased by a lifting magnet 100. The magnet 100 may be battery powered or hydraulically or pneumatically operated.

Instead of the magnet 100, a hydraulic cylinder is used to lift the bell-shaped lifting body 76. A pneumatic drive unit can also be used.

Proximity switch 96 is also shown in FIG. This proximity switch 96 is located on the lid 63. A user in front of the toilet bowl is detected through the window 97.

This detection indicates that the toilet seat is in the raised position and the operating button for the toilet seat rocking mechanism is To allow the toilet to be used as a urinal when the tongue is not activated used for.

This proximity switch is connected to a corresponding flushing mechanism to flush the toilet. used for.

When the rocking motion of the toilet seat is performed via the rocking mechanism described later, the toilet bowl can be cleaned. is started by the control described later.

However, the toilet activates the rocking drive when the toilet seat is in the raised position. When used without a toilet, the proximity switch 96 is associated with its control. Used to supplementally clean the toilet bowl.

FIG. 6 shows a space 8 between the front wall of the cleaning tank 64 and the space 8 between the cross beam 67 at the rear. It is shown that a slit 115 is formed between the rear wall 176 of .

This slit 115 is used to pass the flushing strip of the sanitary cover. the washing The sink piece extends into the toilet bowl when the toilet seat is in the lowered position. child When the cleaning process starts, the cleaning water grabs the rinse strips and this causes the sanitary cover to It is ensured that the bar is drawn into the toilet bowl and flushed.

From FIGS. 6 and 7, it can be seen that the drive shaft 69 is rigidly coupled to the lever 157 and that the drive shaft 69 is A lower bearing 160 is disposed at -157, and a piston of the gas spring 158 is attached to this bearing 160. One end of the tongue rod 159 is hinged, and the other end of the gas spring 158 is connected to the cross beam 67. Fixed.

When rocking the toilet seat clockwise, the force of the gas spring 158 and the hydraulic pressure The spring pressure 84 of the conductor 82 is actuated. The pressure chamber 175 of the hydraulic cylinder 82 As soon as the pressure is released, the gas spring 158 reverses the drive shaft 69 via the lever 157. pulling in the clockwise direction, in which case the spring 84 supports the rocking movement. This rocking motion The toilet seat then swings counterclockwise to the raised position in FIG. 4.

The drive shaft 69 is firmly coupled to an operating pin 103 that cooperates with the microswitch 102. It is. In this case, Figure 6 shows the rocking of the entire mechanism when the toilet seat is in the raised position. It shows the location.

When the toilet seat is rocked downward, the operating pin 103 is rotated clockwise. , position 103', thereby actuating the microswitch 102.

When the toilet seat is swung clockwise, it first moves to its final position, approximately 2" before the final lowered position. The swing position of is detected.

In this swing position, the toilet seat 61 first remains in the position shown in FIG. 4.

Only when the toilet seat 61 is loaded with your body weight, the toilet seat swings by 2'' and descends. The microswitch 102 is operated for the first time in this swing range.

After the toilet seat has been used as specified, the toilet seat should first be lowered by the predetermined 2° swing angle. It swings above the lowered position, and the microswitch 102 is activated again. be done.

The electronic control is now activated and tells you that the toilet seat has been used as intended.

When the microswitch 102 is turned on, the delay circuit is activated. This delay The time can be set, for example, in the range of 5 to 30 seconds.

Only after this delay time has passed has the control valve for cylinder 82 been turned off. This causes the pressure chamber 175 to be in a pressureless state. Then tighten the paper is released, and the gas spring 158 engages with the spring 84 to lift the toilet seat counterclockwise. swings to the raised position.

In this case, the gears 92, 93 rotate in a direction opposite to the direction of rotation shown.

As a result, the cam 104, which is firmly connected to the intermediate shaft 71, is rotated clockwise. In this case, the operating bin 105 at the front free swing end starts operating.

This operating pin 105 abuts against the swinging portion 108 of the pump 106.

Pump 106 is used to initiate the cleaning process.

In this case, the swinging part 108 is connected to the support pin 109 by the piston rod 10 of the pump 106. 7 is swingably supported. This procedure is due to the axial movement of the piston rod 107. This means that the movement can be carried out without significant wear.

As a result, the piston rod 107 is moved in the axial direction, and the pump sleeve 150 generates pressure in the cylinder chamber 151 of the pump 106 against the spring 153. Ru.

This causes positive pressure to be applied to the drive unit in the bell-shaped lifting body 76 via the connection port 152. (not shown in detail), which causes the bell-shaped lifting body 76 to be lifted. Then, cleaning by the tank 64 is started.

In this case, the pump 106 contains water or air as pressure medium.

The lifting magnet 100 illustrated in detail in FIGS. 6 to 8 has a drive mechanism not actuated. , the toilet bowl is used with the toilet seat in the raised position and flushing begins. Start cleaning only when the machine is about to clean.

Lifting magnet 100 is in this case energized by proximity switch 96 and when energized The bell-shaped lifting body 76 for the cleaning tank 64 is lifted via the armature 101, and the cleaning tank 64 is lifted up. Purification begins.

From FIG. 7, the bearings of the various drive shafts 69, 73 can be seen in detail together with the bearings of the intermediate shaft 71. I can understand it.

In this case, the rack 86 meshes with a gear 92 that is firmly connected to the intermediate shaft 71. I know that there is. Furthermore, a stepped cam 15 having a cam track 161 is mounted on the intermediate shaft 71. 5 are tightly connected. This stepped cam 155 operates a switch 156. used for This switch 156 is activated when the toilet seat is being rotated. Deactivate proximity switch 96.

This realizes an AND circuit, i.e. flushing is performed via the rotational drive of the toilet seat. or via proximity switch 96.

Furthermore, the gear 93 connects the horizontal pin 154 to the drive shaft 69 on which the bushing 94 is arranged. It can be seen that they are firmly connected through the

The arrangement can be understood from FIG.

In this case, the transverse pin 169 can be rotated in the free adjustment range 168 of the bushing 64. It can be seen that the drive shaft 69 is firmly connected to the drive shaft 69.

Only when a swing angle of, for example, 35" is exceeded will the transverse pin 169 move to the bush 9. 4 thus entraining the drive shaft 69.

, the meaning of this mechanism has already been explained above.

From FIG. 10, it can be seen that the drive shaft 69 is also rigidly coupled to the lever 170, with its free swinging end It can be seen that a recess is formed in which the wire cable 171 engages. This wa The ear cable is a clamp for tightening and fixing the sanitary cover 66 to the upper toilet seat edge 62. is coupled to the tap device in a manner not shown.

Furthermore, from FIG. 9 it can be seen that the intermediate shaft 71 is firmly connected to the lever 173, When swinging, the lever 172 that is firmly connected to the drive shaft 73 may be hit. I can understand that. As a result, the tightening mechanism is actuated to tighten the lever 172. Ru.

From FIG. 7, it can be seen that the piston rod 159 of the gas spring 158 is driven through the bearing 160. be connected to the free swinging end of the lever 157 which is rigidly connected to the moving shaft 69; I understand.

Only a mechanical valve 162 is shown schematically in FIG. Furthermore, this valve is the entire The mechanism can be replaced with a hydraulic three-boat two-position switching valve.

This valve is connected to the movement of an operating button (not shown in detail) that initiates a rocking movement. It only has the meaning of supplying pressure water to the hydraulic cylinder 82 and draining it again accordingly. Not yet.

As an example, an operating button (not shown) may connect valve 162 via wire cable 163. has been shown to control.

A control valve 164 is present in the internal chamber of valve 162 and has a separate hydraulic control (not shown). This control valve 164 is also present in the device.

This control valve 164 is connected to a tap water pressure connection 165 and a tank connection that leads return water to the tank. Connection port 166 and pressure connection port 176 to the connection port in hydraulic cylinder 82. have.

That is, the control valve 63 is connected to the hydraulic system via the wire cable 163 in a manner not shown. so that the pressure water introduced into the pressure chamber 175 of the cylinder 82 is applied to the pressure outlet 167. controlled.

Instead of the above-mentioned mechanism in valve 63, control via a magnet (not shown in detail) A solenoid valve may also be utilized to control valve 164.

7 and 8 also show that a bell-shaped lifting body 76 is swingably fixed to a cross beam 78. It is also shown that it is biased by a cleaning lever 77 held in a bearing 79. There is.

This cleaning lever 77 is biased by the armature 41 of the lifting magnet 100.

It should be noted that the valve 162 has a structure that protects the mechanism from damage under unacceptably high pressures, for example. Of course, it is also possible to arrange other parts such as pressure reducing valves and filters to reduce the pressure.

FIG. 13 shows a conventional fill valve 178 fed from a tap water connection 170. Ru. Water enters filter 181 through piping 180, passes through piping 182, and then A control valve 164 is reached which is energized by a pond-type pulse magnet 182.

A pressure reducing valve 183 is arranged at the pressure connection port 165, which has a pressure of 2.5 bar or more. pressure is vented via safety valve 184.

Note that this safety valve 184 cannot be lifted up from the position in which the toilet seat has been lowered manually (unfortunately). (when the pressure chamber 175 is swung to the desired position) the pressure inside the pressure chamber 175 increases. It is.

To neutralize such an unacceptable pressure increase, this pressure is routed through line 185. is discharged into tank 64 through safety valve 184 and piping 186.

To ensure that flushing is initiated even when the toilet seat is not in use, piping 188,1 Another hydraulic branch with 89.190 is provided. In this case, the proximity switch A direct valve 187 having a battery-operated pulse magnet 191 controlled by It is provided.

The direct valve 187 is opened under the control of the pulse magnet 191, and the The drive unit 192 for lifting the bell-shaped lifting body 76 is then energized.

This drive unit 192 is in this case a pressure-energized diaphragm which curves accordingly. Consists of rum.

In this case, excess water is returned to tank 64 through piping 190.
