Axle parts (8) have a mounting aperture (10) which fits on a pin (9) attached to the support, to fasten the seat and cover to the bowl detachably. Either side of the mounting portion of the axle part is a projection, the inner one (8.1) holding the seat and the outer one holding the cover, each of which has a bore to receive the respective projection. At least one of the parts, pref. the cover, includes a lateral aperture which is slightly smaller than the associated axle projection.

Description

Toilet seats usually consist of a seat part and a lid part, both of at least one the support part lying on the toilet bowl with fasteners are set over two axis parts like this is known for example from EP-A-0 615 073. It can here, as can be seen from the cited document, the two axle parts each with a separate support part be provided, or it can be a uniform Carrier part can be provided, the two axle parts arranged are.

Because such toilet seats become unsightly over time be or can also be damaged, a easy exchange possibility as given in the cited document is given in that the two axle parts laterally in corresponding recesses be inserted from the sit part and the lid part, the fastening means connected in one piece to the axle parts each in the form of a screw bolt over a Clamping nut to be fixed on the toilet bowl.

Because the bolts because of the different thickness dimensions the mounting edges of the toilet bowl must be designed relatively long, shows the above Publication a quick change option, which thereby is given that the screw channel of the nut laterally is open so that it is close to the attachment point be clipped onto the side of the screw bolt can and only rotates over a short length must be carried out. Using a conical approach on the nut, which is in an appropriate pressure ring engaging with a conical recess should ensure become that under the influence of the attractive forces the mother is not spread. However, this backup is only conditionally functional, since the safety cone only in the area of the last screw turns can be effective so that there is a risk that the mother will still is spread and dissolves. The assembly work is relatively complex in this design.

A fastening arrangement is known from DE-U-89 03 752.9, which has a continuous girder bridge, which over Screw bolts with corresponding screw nuts on the Toilet bowl is set. Seat part and cover part are connected to the carrier part via a spring-loaded snap axis connected. The advantage of this arrangement is basically in that to replace the seat part and cover part the snap axes against the force of the spring withdrawn and then cover part and seat part can be removed. The arrangement is however comparatively complicated in structure and by the Use of springs is only partially corrosion-resistant. Deposits cannot prevent the Snap axes not withdrawn at all after some time can be.

From DE-U-90 13 917.8 an arrangement is known in which again two separate joint parts on the toilet bowl can be set, their fastening nuts as so-called tilt nut are formed. Here is the Screw channel incomplete, so that the mother under inclination on the associated bolts can be pushed on until it stops, then aligned axially, and then in the usual Can be twisted in a rotating manner. In this embodiment the axle part is designed so that at least the Seat part in the joint area with a claw-shaped joint is provided, which is clipped onto the side of the axle can be.

A similar mounting option is from DE-A-43 39 200 known. Two separate joint parts are provided are in the mounting holes on the toilet bowl be inserted and into which a conical, the locking wedge provided with notches is pressed in. Of the Joint part has a claw-shaped receptacle in which Seat part and cover part with corresponding axle elements be clipped in. This gives you the opportunity that the seat part and / or the cover part is replaced can be fixed without the toilet bowl connected joint part must be released. The disadvantage of this The arrangement is that due to a careless burden of the seat part and / or cover part when handling itself can detach one or both parts from the joint part.

Another form of attachment is given in EP-B-0 156 967. With this design there are on the toilet bowl two separate support parts, each via a screw-bolt-nut connection fixed. The two support parts have an upper recess into which an axle part can be inserted from above after the axis part in corresponding joint bores on the seat part and cover part has been inserted in each case. That in the carrier part insertable end of the axis part has a circumferential Groove on, so that in the carrier part via a side opening a locking pin can be inserted through which the axle part is positively secured to the carrier part. Here too, the seat part and cover part have to be replaced possible without the associated support parts from the Toilet bowl must be solved. The disadvantage of this Design is, however, that when replacing each the relevant axle parts must be threaded on site and then in the assignment given by the threading are inserted into the carrier parts and locked with them Need to become. Both with the new assembly as well when replacing this requires considerable assembly effort.

The invention has for its object fastening arrangements to create an easier assembly and a Ensure reliable fixation.

This object is achieved by a Fastening arrangement for a toilet seat, with at least a joint part that can be fixed to the toilet bowl, to which a seat part and a cover part are hinged are at least one lying on the toilet bowl Carrier part with fasteners and two axle parts has, each with two aligned Axle approaches are provided, each a holding part protrude laterally, with the inside against each other directed axles the seat part and the outside directed axles hold the cover part, further the seat part and the cover part each with a hole are provided to accommodate the associated axles and that a hole in at least one of the two parts, preferably the cover part, has a lateral opening, whose clear cross-section is slightly smaller than the diameter of the associated axle shoulder.

Such a mounting arrangement has the advantage that with a one-piece support part with two Axle parts, but especially with two separate ones Carrier parts, each having an axle part for Assembly of the seat part and cover part on the axles of the can be pushed axially and then can be clipped on by a swivel process. Since this is a pivoting of the cover part in its plane of extension is required, it is also ensured that at the loads in normal use Loosening the joint connection is excluded. Especially However, this arrangement is useful if for one Such toilet seat two separate hinge parts each are provided with their own carrier part. With such a Embodiment allows the connection option described above a factory production in such a way that Seat part and cover part with the help of simple joining devices can be put together and as a closed Component can be made available. A joint part is completely through with its axis approaches "Threading" put together while the other joint part with an inward axis approach in the seat part is inserted so that only the cover part through the The above-described pivoting movement on the outward-pointing Axle shoulder is clipped on.

In a further embodiment of the invention is in particular for a mounting arrangement of those described above Art provided that the carrier part on its top is provided with at least one pin, which is an undercut and that the respective associated axis part at the bottom with a receiving opening for the pin is provided on at least part of their Wall is provided with a projection that when inserted Pin engages in the undercut. Both with a support part with two axle parts as well in systems in which each support part has an axle part is provided, this configuration offers the possibility the seat part and the cover part with their axle parts as prefabricated element, which is then manufactured by a Mounted on the pin of the support part, but can also be dismantled for replacement without the Carrier part itself can be detached from the toilet bowl got to. With this conception one makes advantage of the Fact use that at least the axle parts from one Plastic are made so that here a certain elasticity given in the region of the receiving opening in the pin is so that the connection between the toilet seat and Toilet bowl like a push-button connection he follows.

In a further embodiment according to the invention, in particular for the above mounting arrangements provided the carrier plate on its underside with at least one undercut groove for receiving a holding plate is provided on the fastening means. The carrier plate can in turn be used as a common base plate be designed for two axle parts or as separate mountable carrier plate for one axle part each the bottom is used in conjunction with the Holding plate of the fastener, for example is formed by a bolt, the possibility given the toilet seat before the final bracing Align and adjust the fasteners exactly. It is useful here if the screw bolt is asymmetrical is connected to the holding plate, so that by relocating the holding plate in the undercut groove the carrier plate different orientations of the axis of the bolt to that by the arrangement of the axle part or the pin on the top of the holding plate predetermined orientation is possible.

In a further embodiment of the invention is for fastening arrangements of toilet seats, especially in the Embodiments according to the invention described above, but also for conventional mounting arrangements pressure ring that can be pushed onto the screw bolt, one up to the free end of the bolt has conically widening push-through opening, and a clamping nut is provided for the screw bolt a base body provided with a smooth through hole which is followed by a threaded part, the at least one resilient, on the inside with has part of the thread provided tongue that on the outside with a tapered end of the tongue conical pressure surface is provided. The thread on the resilient tongue is in the usual form with the thread of the bolt engaged so that the Clamping nut can be screwed on normally. The design However, has the advantage that the clamping nut for assembly without turning the bolt axially so far can be pushed on until the free end of the resilient, threaded tongue into the conical extension of the push-through opening on the pressure ring. The tension nut is initially in the axial direction according to Art held by a spring ratchet. Only when conical Pressure surface of the tongue on the corresponding counter surface Do not move the tongue outwards on the pressure ring the nut is screwed in the usual way, being over the conical surface of the pressure ring on the one hand and the conical pressure surface on the tongue on the other hand an increasingly radially inward direction acting contact force between the bolt and the Threaded part of the tongue of the clamping nut takes effect, so that a reliable screw connection is given. Conveniently the clamping nut is designed so that two in Axes seen diametrically opposite tongues are provided with a threaded part, so that on the one hand a perfect pluggability of the clamping nut up to Stop on the pressure ring is guaranteed and on the other but an effective screw connection is possible.

To loosen it, it is sufficient if the clamping nut by a few thread turns is unscrewed, so that the The clamping nut is pulled off in a simple axial movement can be.

As can be seen in FIG. 1, the toilet seat 1 has one Seat part 2 and a cover part 3. These two parts the toilet seat are hinged to a joint part 4, the one on the toilet bowl 5 support part 6 with fasteners 7. With this one illustrated embodiment, an axle part 8 is detachable connected to the carrier part 6. The connection of the two Parts are made as will be explained in more detail below is, via a pin 9 connected to the carrier part 6, to which the axle part 8 can be plugged in the manner of a push button is. This gives the possibility that the Toilet seat 1 can be detached from the toilet bowl can be solved without the fasteners 7 here have to.

Fig. 2 shows the view of the mounting arrangement acc. Fig. 1 in the direction of arrow A in Fig. 1. Here is too recognize that the attachment of the toilet seat 1 over two separate hinge parts 4 takes place. There is nevertheless the possibility of designing the fastening arrangement in such a way that only a single carrier part 6.1 is provided, such as here indicated by dash-dotted lines, which accordingly over two fasteners set on the toilet bowl 5 is. Otherwise, the structure of the overall arrangement unchanged.

Like FIG. 2 and the enlarged views in FIGS. 3 and 4 can be seen, the two axle parts 8 to one open at the bottom receiving opening 10, at least on part of its wall with a projection 11 is that when plugged onto the pin 9 in a corresponding Undercut 12 of the pin 9 engages, see above that the toilet seat is firm but detachable with the hinge parts 4 is connected.

The axle part 8 is with two side axles 8.1 and 8.2 provided, of which the axis approach 8.1 in a corresponding hole in the seat part 2 is inserted while the axis part 8.2, which in the illustrated embodiment is conical, in a corresponding bore is inserted in the cover part 3.

Assemble the two parts 2 and 3 of the toilet seat 1 to be able to, one of the axis part 8, as from the Sectional view can be seen, in each case in the corresponding Drilled holes.

The other axis part 8.4 is then with its axis approach 8.1 threaded into the seat part 2. The hole in the cover part 3 has on one side, here on the axle part 8.4 associated side, a side opening 13, the clear cross-section is slightly smaller than the diameter the associated axis approach. Then that is the Possibility of pivoting the cover part 3 in its design level on the axis approach 8.2 of the axle part 8.4 clip on the side. The toilet seat forms with it a complete structural unit that, after appropriate attachment of the joint parts 4 on the toilet bowl 5 on the Pin 9 can be "unbuttoned" or can also be removed for cleaning and repair purposes.

3 and 4 show the joint part 4 in an enlarged view with attached axle part 8. From the enlarged Illustration shows that the pin 9 is an undercut 12, in which a corresponding projection 11 engages on the wall of the receiving opening in the axle part 8. The arrangement is such that the Receiving opening 10 has a lateral opening 14 (Fig. 3), so that in the manufacture of the axle part 8 made of plastic a corresponding slide is introduced here through which the projection 11 into the receiving opening 10 can be molded. During the pin 9 with its Undercut is rotationally symmetrical, is sufficient it if only in the receiving opening 10 of the projection 11 on a wall of the receiving opening in the form of a rib or the like. is molded. With appropriate dimensioning even with stable plastic materials Elasticity of the plastic material to ensure reliable Fixed snap connection between the axle part and the pin to cause the toilet seat in normal use holds securely on the toilet bowl.

The hinge part 4 with its support plate 6 and its Fastening means 7 can be formed in one piece be. However, it is expedient, as in FIG. 5, in three views shown when the carrier plate 6 with their Pin 9 on the underside with an undercut Groove 15 is provided, in which the fastener 7, the is designed in the form of a bolt can be. For this purpose, as shown in FIG. 5, the screw bolt 7 provided with a holding plate 16, which is asymmetrical is arranged to the axis 17 of the bolt as this is also indicated in Fig. 5.3. Since the pin 9, like Fig. 5.1 reveals eccentrically on the carrier plate 6 is arranged, there is thus the possibility of a corresponding insertion of the screw bolt 7 in the undercut groove 15 to make the arrangement that the axis of the bolt 17 with the axis of the Pin 9 coincides. Put the bolt 7 rotated by 180 ° into the undercut groove 15, then the axis 17 of the bolt is at a distance to the axis of the pin 9. By the undercut ensures that the screw bolt 7 with its holding plate 16 in the direction of arrow 18 (Fig. 5.3) also can be moved laterally, so that an exact alignment of the joint part 4 possible on the toilet bowl is.

For fastening the joint part 4 to the toilet bowl 5 is on the bolt 7, as in Fig. 1 but also 3 and FIG. 6 shown in an exploded view, first pushed a pressure ring 19. As can be seen in FIG. 6 can, the pressure ring 19 has a conical downward widening push-through opening 20. For simplification the assembly can be preferably made of plastic Pressure ring 19 in the area of its narrowest diameter be provided with two thin noses 21, the clear distance between them is slightly less than the tip diameter of the thread of the bolt 7. It is possible to push the pressure ring 19 onto the screw bolt for assembly, whereby it is ensured via the lugs 21 that the pressure ring 19 no longer from the screw bolt 7 can slide down, but can be easily pulled off by hand can be.

To fix the joint part 4 is that shown in Fig. 6 Clamping nut 22 is provided, which is a basic body 23 which has a smooth through hole 24 is provided, the diameter of which is larger at the narrowest point is the outside diameter of the thread on the bolt 7. There are two resilient tongues 25 on the base body 23 provided that each with a Part of the thread 26 are provided. The thread 26 on the both tongues 25 is related to a normal nut thread designed for the thread on the bolt 7, so that the clamping nut 22 basically on the screw bolt can be screwed on in the usual way.

However, since the thread 26 only in the area of resilient tongues 25 is arranged, the clamping nut 22nd for the purpose of assembly first from below by a axial movement pushed onto the bolt 7 be, the mutual thread like a Ratchet work. The clamping nut 22 is so far pushed on until the resilient tongues 25 on their Conical pressure surfaces 27 provided on the outside conical inner surface of the push-through opening 20 of the pressure ring 19 come to the plant. Only from that moment on the clamping nut must be turned in the usual way here the additive forces for fastening the associated joint part to be able to muster. When turning the clamping nut 22 the contact pressure is increased with which the resilient Tongues 25 pressed onto the thread on the bolt 7 will. To release the clamping nut 22 is first in reverse Direction turned until the resilient tongues from the conical through opening of the pressure ring 19 get free. Then the clamping nut 22 can be turned without further rotation simply pull off in the axial direction.
