Description

The present invention describes a device for releasably securing a toilet seat and / or toilet lid to a toilet bowl and a corresponding method thereto.

The device according to the invention is used to attach toilet seats and / or toilet lid to a toilet bowl. Thus, the device of the invention finds its application in the installation of sanitary facilities.

From the prior art it is known that toilet seats or toilet lid are screwed to the toilet bowl. Here, corresponding holes are provided in the toilet bowl, are added to the threaded rods, which in turn are attached to the toilet seats and / or toilet lids to be mounted. After passing through the threaded rods, these are in a suitable manner screwed. The result is a firm connection between the toilet lid or toilet seat and the toilet bowl.

Since you absolutely need tools in this attachment process, the process is not by anyone to accomplish and also not to be described as simple. Should the toilet seat or toilet lid ever have to be damaged and replaced, the disassembly of the toilet seat and the toilet lid should not be so complicated that tools are required.

For this purpose known solutions in which no threaded rod is used, but a plug-in system. Here, the toilet seat or the toilet lid is placed on the toilet bowl and mechanically locked in a suitable manner. When disassembling this device, a dedicated button or button must be pressed to release the lock. Thereafter, the dismantled toilet seat and / or toilet lid can be removed from the toilet bowl.

A disadvantage of this type of assembly or disassembly is that the removal of the toilet seat or the toilet lid from the toilet bowl turns out to be very difficult if only one hand is available. This is the case, as the second has to press the corresponding button or button. Thus, this procedure is not to be described as a simple disassembly.

The document CN 201 595 766 U describes a device for releasably securing a toilet seat. In this case, at least one pin is provided which can be introduced into an opening in a rotary spindle in order to fasten the toilet seat to a toilet bowl. To secure and to release the pin in the opening, a button is provided laterally on the device. This must be operated to attach the toilet seat to the toilet bowl and to release it again.

Object of the present invention is therefore to provide a device for releasably securing a toilet seat and / or a toilet lid to a toilet bowl, which does not have the above-mentioned disadvantages and thus can be described as simple. Simple Mondays are therefore also necessary for toilet seats and toilet lids, since nowadays toilet lids and toilet seats are provided with various designs and you can mount the toilet bowl with toilet seats provided with different decors on the toilet bowl by means of a simple releasable attachment, as needed.

This is solved with the characteristics of the main claim. Here, a support is provided which can be fastened by means of fastening means to the toilet bowl. This may further be a threaded rod which is screwed on, or detent clips or similar methods for attachment to the toilet bowl. Furthermore, at least one pin is provided, and for each pin in each case a passage.

There are two main possible embodiments provided, namely a first, in which the pins are attached to the carriers and thus by means of the carrier to the toilet bowl. In this embodiment, the corresponding bushings are then attached to the toilet seat and / or to the toilet lid. In this embodiment, the toilet seat or the toilet lid is then placed on the support, so that the pins which are arranged on the carrier, are guided through passages, which are then arranged on the toilet seat or toilet lid.

In a second embodiment, the pins are attached to the toilet seat or toilet lid and the corresponding bushings on the carriers. When placing the toilet lid or the toilet seat in this Embodiment then the pins, which are attached to the toilet seat or toilet lid, inserted into the corresponding passages on the support.

Finally, a combination of these two embodiments is possible in which at least one pin is attached to the toilet seat or toilet lid and at least one other pin on the carrier. Correspondingly many bushings must then also be attached to the toilet lid or toilet seat and on the support.

So that the toilet seat or toilet lid to be fastened is held on the toilet bowl, at least one blocking element is provided, which can be introduced into the passages. This locking element is such that it can exert a force on the pins upon insertion of the pins in the bushings to hold them in position. To enable this, the pins are each provided with a groove and upon insertion of the pins in the bushings, the locking elements come into operative connection with the grooves. The blocking elements can in this case z. B. consist of ring springs. Now, if the pin is inserted far enough into the passage, the blocking element enters into operative connection with the groove and holds the implementation in this position on the pin. The toilet seat or the toilet lid is now releasably connected to the toilet bowl and the device is placed in a composite state.

In order for the blocking element to exert a force on the journal, it must be widened upon insertion of the journal into the passage in such a way that the journal can be passed through the blocking element. To facilitate this process, in a particular embodiment, the pin is tapered to the side which is inserted into the bushing. As a result, the expansion of the blocking element is simplified. The groove in the pin is then mounted in the insertion direction of the pin behind the conical inlet, so that the blocking element is first widened over the pin and then can enter into operative connection with the groove.

To solve the toilet seat or toilet lid now again from the toilet bowl, overcoming the force of the locking elements on the introduced pins or the grooves of the introduced pin is necessary. The toilet seat or the toilet lid is pulled away from the toilet bowl with such a strong force that the locking elements are released from their operative connection with the grooves. Again, the locking elements are expanded and that the pins can be dissolved out of the bushings again. The device is in this case put in the release state. This simple attachment of the toilet seat or toilet lid to the toilet bowl can, without the help of a tool and without pressing a button, buttons or similar element at any time the toilet seat or the toilet lid removed from the toilet bowl and reapplied. Likewise, one has both hands available for it.

The blocking elements can be firmly inserted into the bushings or, in a particular embodiment, can be fed through recesses of the bushing. These recesses are then led out from the bushings to one side, so that the blocking elements can be assigned to the bushings or can be taken out of the bushings again.

In order to enable the normal folding movement of the toilet seat or the toilet lid after installation of the toilet seat or the toilet lid to the toilet bowl, in a particular embodiment, at least one rotary spindle is provided, which may either be part of a normal hinge, or which is roughly cylindrical and in appropriate recordings in the toilet seat and / or toilet lid can be introduced.

In the case where the rotary spindle is part of a hinge, then the hinge is attached to the toilet seat and / or toilet lid by means of conventional fastening means, such as screws.

In the case of the introduction of the rotary spindle in toilet seat or toilet lid, the rotary spindle forms the axis of rotation of toilet lid or toilet seat. In this embodiment, the toilet lid or toilet seat has corresponding seats in which the rotary spindle is introduced. Within this receptacle, the rotary spindle is rotatably mounted and thus the toilet seat or the toilet lid can rotate about the rotary spindle to allow the folding movement.

Whether the rotary spindle is incorporated as a rotation axis in recordings of the toilet seat or toilet lid or is formed as part of a hinge which is attached to toilet lid or toilet seat, then either at least one pin or at least one bushing is attached to the rotating spindle. About the rotary spindle so at least one pin or at least one implementation associated with the toilet seat and / or toilet lid.

In a further particular embodiment, a spring is associated with each rotary spindle to position the rotary spindle in the receptacle of the toilet seat or the toilet lid. Likewise, this spring ensures that the toilet seat does not come off the toilet lid in the composite state.

Also, in a particular embodiment, a damping can be incorporated in the rotary spindle to dampen this folding movement during the folding movement of toilet lid or toilet seat.

In order to hold the locking elements supplied via the recesses in the bushings, optional covers are provided for each recess. The covers are placed on the carrier or the rotary spindle, depending on which part is provided with a passage. The cover then covers the recess of the implementation. In order to hold the cover in position, optional clamping means may be provided.

If a special design of the hinge, for example, when the rotary spindle is introduced into recordings of the toilet seat or the toilet lid, the bushings, when they are arranged on the rotary spindle, not be accessible when installed, recesses are provided for each implementation. This allows the pin to be introduced into the respective implementation can.

The method for releasably securing a toilet seat and a toilet lid to the toilet bowl by means of the aforementioned device then works so that at first for transferring the device in the composite state at least one blocking element is inserted into a respective rotary spindle through the respective recess. If covers provided must be removed beforehand to allow access to the recess. Subsequently, the blocking element is fed through the recess of the respective implementation. The locking element must now be aligned so that it is aligned at the position of the respective passage to allow the penetration of a pin in the implementation.

When using covers, a cover is now attached to each recess to hold the locking elements in position.

The toilet seat or toilet lid is now placed on the support in such a way that the pins are inserted into the openings provided for this purpose. In this introduction process, the locking elements located in the bushings are widened so far that the respective pin can be performed by the respective implementation and thus the respective blocking element. In the particular embodiment of the conically tapered pin favors by the conical inlet when attaching the pin-increasing radius of the pin, the introduction of the same in the implementation and the blocking element and the expansion of the blocking element.

If the pin is inserted far enough into the passage, the respective blocking element comes into operative connection with the groove on the pin, so that the bushing is held on the pin or the pin in the bushing.

Hereby, the composite state is reached, in which the toilet seat and / or the toilet lid is releasably attached to the toilet bowl.

To transfer the device into the release state, a force must now be applied in the longitudinal direction of the pins, which means that the toilet seat or toilet lid is moved away from the toilet bowl. If in this case the force which exerts the blocking element in the groove on the pin, overcome, the blocking element is again expanded so far that the Locking element slips out of the groove. Then the pins can be pulled out of the bushings again. As a result, the release state is achieved.

After pulling the pins out of the bushings, when the covers are used, they can be removed again from the recesses and, if necessary, the blocking elements can be removed from the bushings via the recesses.

In Fig. 1 a carrier 1 can be seen, with a pin 11. This carrier 1 is in this embodiment via a threaded rod on the Toilet bowl mounted, which is located on the opposite side of the pin 11 itself. After mounting the carrier 1 to the toilet bowl, this pin 11 thus points away from the toilet bowl and is thus able to receive a corresponding toilet seat 6 and / or toilet lid 7.

The pin 11 has at the end, which is opposite to the carrier 1, a conical inlet and the conical inlet then a groove 12. This groove 12 is smaller in diameter than the rest of the pin 11, so in the installed state, the locking element 3 in the groove 12 can engage and is held in the groove 12.

In this embodiment, a rotary spindle 2 is provided with the passage 21, in which the pin 11 is received during assembly. Clearly visible is the recess 22 which is led out of the rotary spindle 2 to fit a blocking element 3 in the passage 21. The blocking element 3 is in this embodiment, an annular spring, which can then be inserted into the recess 22 and to the extent that the interior of the locking element 3 with the passage 21 matches, so when mounting the pin 11 passed through the passage 21 and the blocking element 3 can be. So that the blocking element 3 does not slip out of the recess 22 again, a cover 4 is provided, which is placed on the rotary spindle 2 by means of latching lugs in order to cover the recess 22. The detents engage in this case in designated recesses in the rotary spindle 2 a.

If the rotary spindle 2 provided with the blocking element 3 is then placed on the journal 11 or the journal 11 is inserted into the leadthrough 21 of the rotary spindle 2, the blocking element 3 is expanded by the conical inlet of the journal 11 during the passage. To make this possible, the locking element 3 must have a smaller inner radius than the pin 11 at the widest point.

Upon further insertion of the pin 11 through the passage 21, the locking element 3 now slips into the groove 12. Since the groove 12 again has a small radius than the rest of the pin 11, the locking element 2 enters into operative connection with the groove 12 and thus holds the rotary spindle 2 on the pin 11 in position.

The thus mounted rotary spindle 2 on the pin 11 is in Fig. 2 to see. The blocking element 3, in this case an annular spring, is in operative connection with the groove 12. In order to expand the blocking element 3 when inserting the pin 11, it is necessary to ensure that sufficient expansion space is provided in the recess 22 for the blocking element 3.

Also visible is the mounted cover 4, which closes the recess 22 to the outside. The rotary spindle 2 is now placed on the pin 11 and thus on the carrier 1 and holds in position.

In this embodiment, two such rotary spindles 2 are provided for mounting a toilet seat 6 and a toilet lid 7. Such an assembly is as an exploded view in Fig. 3 shown. The toilet seat 6 has here recordings 61, for the two rotary spindles 2. After mounting the rotary spindles 2 off Fig. 1 with blocking element 3 and cover 4, these are inserted into the receptacles 61. In this embodiment, the rotary spindles 2 act simultaneously as a hinge axis for toilet seat 6 and toilet lid 7. This works are also recordings on the toilet lid 7 are provided, which then partially protrude over the rotary spindles 2. The remaining part of the rotary spindles 2 is introduced into the receptacles 61 of the toilet seat 6.

So that this assembly works and the spindles 2 are held in position, springs 5 are provided, which press the rotary spindles 2 outwards after installation of the rotating spindles in the toilet seat 6 or toilet lid 7 and thus in their position half in the recordings Toilet lid 7 and half held in the receptacles 61 of the toilet seat 6.

When introducing the rotary spindles into the corresponding receptacles 61, therefore, first the spring 5 is introduced and then provided with locking element 3 and cover 4 rotary spindles. Contrary to the spring force 5, the rotary spindles can now be pushed so far into the receptacles 61 that the toilet lid 7 with his recordings for the rotary spindle 2 can be positioned over it. The toilet lid 7 must be positioned so that the interior of the receptacles forms an axis with the interior of the receptacle 61 of the toilet seat 6. Once this is the case, push the springs 5, the corresponding rotary spindles 2 outwardly into the receptacles of the toilet lid 7. toilet seat 6 and toilet lid 7 are then mounted together and are hinged about the axes of the rotary spindles. 2

In order to ensure a damping when folding the toilet seat 6 and the toilet lid 7, if necessary, a damping in the rotary spindle 2 can be installed. The rotary spindle 2 itself has an axis of rotation and is composed of two parts which are rotatable relative to each other. The one part which is introduced into the receptacles of the toilet lid 7, it has a profile which coincides with the shape of the receptacles of the toilet lid 7, so that in the recording of the part of the rotary spindle can not move about its axis and thus is stationary. The other part of the rotary spindle 2 is rotatable relative to this first part. A corresponding damping is then introduced into the rotary spindle 2.

Since when turning the toilet lid 7 then the rotary spindle 2 is rotated about its axis, engages in the rotary spindle 2 located damping and dampens the folding movement of toilet seat 6 and toilet lid. 7

Thus, the pins 11 can engage in the passages 21 of the rotary spindles 2, 6 recesses 62 are provided in the toilet seat and that at the same height as in the assembled state, the bushings 21 in the Spindle 2 are positioned. Thus, when mounting the toilet seat 6 or the toilet lid 7, the pin 11 is first inserted into the recess 62, then into the passage 21 of the rotary spindle 2. In this insertion of the pin 11 in the lead-through 21 of the rotary spindle 2, as already described, the locking elements 3 in the grooves 12 of the pin 11 a. Toilet seat 6 or toilet lid 7 are thereby held in position and reach the composite state.

The embodiment in Fig. 4 has the reverse operation as the embodiment of Fig. 1 , Here, the carrier 1 has the passage 21 and the pin 11 is attached to the rotary spindle 2. The rotary spindle 2 itself is part of an external hinge, which is screwed over the two mounting surfaces shown toilet seat 6 and toilet lid 7. In this embodiment, a damping in the rotary spindle may be provided, since the two outer parts can be rotated with the mounting surfaces relative to the rotary spindle 2 in one axis. In this axis then the damping can be provided to ensure the folding movement of the mounted toilet seat 6 and the toilet lid 7.

As in Fig. 1 a blocking element 3 is fed through the recess 22 of the bushing 21. Again, the blocking element 3 is shown as a ring spring. In this embodiment, it can be clearly seen that the blocking element 3 has a nose, which engages in a corresponding omission when inserted into the recess 22. This is because blocking element 3 can not be twisted and can be positioned better in the passage 21 in the recess 22.

The cover 4 is placed over the carrier 1 in this embodiment, so that the recess 22 is concealed and the blocking element 3 can not slip out of the recess 22. The cover 4 has a hole here, so that the application 21 is not obscured when attaching the cover.

The pin 11, which is attached to the rotary spindle 2, also has a groove 12 and outwardly a conical inlet. The assembly is thus the same as in the embodiment in Fig. 1 however, is in its implementation as a kinematic reversal to the embodiment of the embodiment in FIG Fig. 1 consider. After insertion of the pin 11 in the passage 21, the locking element 3 slides into the groove 12 provided on the pin 11 and holds the hinge and thus the toilet seat 6 and toilet lid 7 in position.

The assembled state of the embodiment of Fig. 4 is in Fig. 5 shown. Again, it can be clearly seen how in the composite state, the locking element 3 engages in the groove 12 and the pin 11 and thus toilet seat 6 and toilet lid 7 holds in position.

Fig. 6 shows once again as an exploded view of the mounted on the hinge toilet seat 6 and the toilet lid 7. Again, the blocking element 3 is first positioned by the recess 22 in the passage 21 and provided with the cover 4. Thereafter toilet seat 6 and toilet lid 7 are inserted via the pins 11 in the passage 21, wherein the locking elements 3 are widened over the conical inlet of the pin 11 and enter into operative connection with the underlying groove 12. As a result, the toilet seat 6 and the toilet lid 7 are held in position in the composite state.

In all the embodiments shown, the dismantling, ie the transfer of the device from the composite state to the release state works by the toilet seat 6 or toilet lid 7 is pulled away from the toilet bowl with a force that must be greater than the force that the Locking element 3 holds in operative connection with the groove 12. By applying such a force, the blocking element 3 is widened so far that it is released from the operative connection of the groove 12 and the pin 11 can be pulled out of the blocking element 3 and the bushing 21 again. Thereafter, the device is in the release state. By this simple Attachment of toilet seat 6 or toilet lid 7 to the toilet bowl can, without the aid of a tool and without pressing a button, button or similar element at any time the toilet seat 6 and the toilet lid 7 are removed from the toilet bowl and reapplied. Likewise, one has both hands available for it.

The invention is not limited to the above-mentioned features. Rather, further embodiments are conceivable. For example, instead of an annular spring, the blocking element can also be a snap ring or a spring of a different type. Likewise, it is conceivable that the spring is already introduced in the device and is not designed to be guided outwards. Apart from the two embodiments shown, it is also conceivable that a combination of both embodiments is realized, ie, some pins are located on rotary spindles and others on the carrier. Accordingly, of course, just as many feedthroughs must be provided on the rotating spindles and the carrier.
