Description

Toilet seat hinge and

Toilet seat set

description

The invention relates to a toilet seat hinge according to the preamble of patent claim 1 and a toilet seat set according to claim 23.

To attach a toilet seat set to a ceramic sections of toilet seat joints, over which the rotating movement of the toilet seat set against the ceramic and the rotating movement of the toilet lid relative to the toilet seat are possible.

A generic toilet seat hinge is known for example from the document DE 20 2014 101 077 U1. It is suitable for attaching a toilet seat set with a toilet lid and a toilet seat to a ceramic. It has a ceramic side mountable hinge pin, which is insertable into a receptacle of an adapter piece of the toilet seat joint. Transverse to the longitudinal axis of the hinge pin, a locking element is displaceably guided in the adapter piece, which engages in a Verrastungsposition in a circumferential groove of the hinge pin, whereby the adapter piece - and thus the toilet seat set - is fixed to the hinge pin. In a release position, which is taken against a spring force upon actuation of the latching element, the latching element releases the hinge pin, so that the adapter piece, or the toilet seat set, is removable from the hinge pin.

A disadvantage of this solution is that the operating buttons of both toilet seat joints must be pressed permanently by the operator to remove the toilet seat. For the operator, it may then be difficult to remove the toilet seat set, as he must simultaneously press the operation buttons and at the same time pay attention to a tilt-free removal of the toilet seat set.

On the other hand, the present invention seeks to provide a lockable toilet seat hinge, which for the operator in a more comfortable way from the hinge pin is removable. Furthermore, the invention has for its object to provide a toilet seat set with such a toilet seat hinge.

These objects are achieved by a toilet seat hinge with the features of claim 1 and by a toilet seat set with the features of claim 23.

Advantageous developments of the toilet seat hinge are written in the dependent claims.

A toilet seat hinge for attaching a toilet seat set to a ceramic has a pivot axis about which the toilet seat set, in particular a toilet seat and / or a toilet lid, is pivotable. The toilet seat hinge further has an adapter or an adapter piece, in which a receptacle for a hinge pin is formed. The adapter or the adapter piece is preferably at least partially formed of fiber-reinforced material, so as to achieve a high rigidity and strength of the toilet seat hinge. The recording can be performed for example as a bore, in particular as a blind hole or through hole. The toilet seat hinge has to set the adapter, and thus the toilet seat set, a detent element on the hinge pin. This can take at least two positions. A latching position, via which the adapter is fixed to the hinge pin, and in which the latching element at least partially engages in a circumferential recess of the hinge pin, and a release position in which the latching element releases the circumferential recess, in which it is lifted, for example, from the peripheral recess. According to the invention, the latching element can be arrested or secured in the release position by engagement with the hinge pin inserted at least in sections into the receptacle by operative engagement therewith.

When inserted hinge pin, ie, when mounted on the hinge pin toilet seat hinge, there is thus the possibility of permanently setting and locking the locking element in the release position without further action of the operator. Then, the operator can easily solve the toilet seat hinge, or the toilet seat set of the one or more hinge pins in a simple manner, without permanently unlocking the locking element by hand. He can therefore rely solely on the lift-off or solution concentrate and does not need to additionally hold the locking element in the release position, for example by pressing.

In a preferred embodiment, the locking element jumps after lifting the hinge pin in a starting position, in particular in its Verrastungsposition back.

In a preferred embodiment, the toilet seat hinge in addition to the hinge pin.

In a development, the latching element is substantially rigid, that is designed inelastic. Then, for example, it is translationally and / or rotationally movable into the release position.

In a preferred embodiment, the latching element is resilient and elastically deformable in the release position. Since the latching and release is thus not effected solely by a translational and / or rotational position change of the latching element but by its elastic deformation, the toilet seat hinge is comparatively simple in terms of its apparatus and is well protected against wear. The locking element is preferably formed with an approximately round cross-section, whereby it has a good flexural rigidity and is protected against wear.

In a further development, the latching element can be actuated via an actuating element of the toilet seat hinge and thus elastically deformable. In the case of said development that the latching element after lifting off the hinge pin in an initial position, in particular the Verrastungsposition, springs back, then also jumps the actuator back to the starting position.

The release is preferably carried out in a simple manner by elastic defor- mation, the locking in a simple manner by resetting by means of elastic restoring forces of the locking element. In one development, the latching element has at least one spring leg supported on a support, which is in particular fixed to the adapter, which engages at least in sections in the circumferential recess in the latching position.

In a further development, the locking element for the purpose of its locking in the release position via an actuating element with the hinge pin and / or coupled to the adapter, in particular coupled. The movable actuator thus couples the rigid or elastically deformable designed locking element in the release position with the positionally fixed hinge pin and / or the positionally fixed adapter. In this way, the locking in the release position with an already existing element (the actuator) can be done without having to hold a special locking element.

In a development, for this purpose, the actuating element on the adapter or on the hinge mandrel form-fitting and / or non-positively fixed, in particular fixed.

To achieve this, in a development in the release position of the hinge pin from the actuating element in a direction transverse to the recording or engaged behind, in particular um- or engaged behind. The Um- or rear handle provides a simple solution for positive and / or non-positive coupling of the actuating element with the hinge pin.

In one variant, the wraparound is incomplete. It then extends maximum to a diameter of the hinge pin zoom. This diameter is then not surrounded and behind.

In a further development, the actuating element has at least one section which can be clamped, in particular clamped, in the release position between the adapter and the hinge pin. By means of the clamping the determination of the actuating element, and thus the locking of the locking element in the release position, are particularly safe. In order to initiate clamping forces occurring as symmetrically as possible in the actuating element, the actuating element in a development on two approximately diametrically opposed portions which are clamped in the release position respectively between the adapter and the hinge pin, in particular clamped.

In one development, the portion or the sections are each designed substantially wedge-shaped and are in the release position in each case with a first wedge surface with the adapter and with a second wedge surface with the hinge pin in contact brought, in particular brought. In this way, from the sections resulting from the elastic deformation of the locking element spring force on the adapter and the hinge pin can be transferred.

In a further development, in the release position, the second wedge surfaces of the sections of the actuating element outside the peripheral recess with a free, d. H. ceramic remote end portion of the hinge pin can be brought into contact, in particular brought. This avoids that the portions of the actuating element when removing the toilet seat hinge from the hinge pin with its second wedge surfaces in the circumferential recess, which would cause an unwanted latching.

For this purpose, the free end portion in one direction, in particular in a withdrawal direction of the toilet seat joint from the peripheral recess towards a tip of the hinge pin, designed so smooth and / or tapered that the second wedge surfaces are easily derived in this direction at the free end portion ,

Thus, the actuator is easily reset when loosening the clamp back to its original position, the wedge surfaces are each hired at an obtuse angle against a direction of action of the spring force. Is the toilet seat hinge released from the hinge pin, the adapter facing first wedge surfaces can easily slide on the adapter and the provision of the actuator is done without entanglement.

In an alternative development, only the first wedge surfaces are each made at an obtuse angle to the effective direction of the spring force. The two- th wedge surfaces are then aligned substantially parallel to the effective direction of the spring force.

In one development, the actuating element has approximately two diametrically arranged arms, on each of which one of the sections is arranged. These arms can in the aforementioned manner the hinge pin with its sections or engage behind. The sections are preferably each arranged at the free end portion of the arms.

In a further development, the arms are resilient and are expandable upon actuation of the actuating element by the hinge pin.

In one development, the adapter has two approximately diametrically opposed support elements with support surfaces on which, for the purpose of locking the latching element in the release position, one of the first wedge surfaces can be supported, in particular supported. The support elements are preferably elastically or resiliently deformable laterally outward. This is realized for example in that the support elements, unlike the rest of the adapter is preferred, are made of a material without fiber reinforcement.

In a further development, the adapter has a detachable adapter section on which the support elements are arranged. Thus, if necessary, the locking function can be removed by simply removing the adapter piece and added by later reassembly.

Preferably, the locking element in addition to the first, a second, supported on a second support spring leg, which engages at least partially in the latching position in the circumferential recess and is also deformable to release via the actuating element elastically in the release position. As a result, in the latching position, the latching force is advantageously transferred symmetrically to the hinge pin. The peripheral recess is preferably formed as a full circumferential groove, which is easy to manufacture. It may alternatively be formed in separate sections and divided, so that each spring leg engages in its own, separate from the other section.

In a further development, the hinge pin has an additional peripheral recess, preferably in the form of a circumferential groove, in which a sealing element cooperating with an inner lateral surface of the receptacle is arranged. In this way, an arranged in the direction of insertion of the hinge pin, inner region of the receptacle in which the mechanism is provided for locking, sealed against the ingress of dirt or aggressive media, whereby the mechanism is well protected against wear and corrosion. In addition, the placement of the toilet seat hinge on the hinge pin and the removal of this takes place in a muted, soft way that improves the feel of handling. Preferably, the additional circumferential recess of the first-mentioned circumferential recess is arranged in the direction of the ceramic side.

The sealing element is preferably designed as a sealing ring, for example as an O-ring.

In a further development, the spring legs and the supports, in particular with respect to a plane defined by a central axis of the hinge pin plane, formed substantially symmetrical and / or arranged.

In a development, the spring legs are coupled via a connecting portion of the locking element arranged between the supports, which can be acted upon by the actuating element for actuating the locking element in the release position with a force, in particular a transverse force, in particular a compressive force. Alternatively, it is of course possible to initiate the force on the locking element not between the supports, but instead in an area beyond the supports, in which case optionally instead of a simple support as storage a clamping of the locking element is provided. In a further development, the adapter has a wedge, slide on both sides of the particular end portions of the two spring legs when actuated by the actuating element. Thus, a spreading of the spring legs and their lifting out of the circumferential recess in the release position.

The connecting portion is preferably formed via a straight or a curved leaf spring portion or a ring spring portion. The latter allows, for example, on the choice of a number of turns a fine adjustment of the operating force. In order to have sufficient space in the adapter for an actuation travel or stroke, in a preferred development, the spring legs extend from the connection section towards the supports substantially at an obtuse angle, which is open towards receiving. Alternatively, of course, the angle can also open away from the receptacle or have about 180 °.

Preferably, the spring leg (s) are or are bent in an area of the respectively assigned support towards the receptacle. In this area, the spring leg may be formed, for example, by bending.

In a further development, at least free end portions of the spring legs are accommodated at least one shaft which is in particular fixed to the adapter. The shaft is open towards the circumferential recess of the hinge pin. As a result, the locking element is forcibly guided in the adapter with the end portions, so that an unwanted rotation of the spring legs is prevented when not received in the recording hinge pin.

In a further development, the shaft is subdivided via a web into two shaft sections for receiving in each case one of the spring legs or in each case one of the free end sections.

In order to support a spreading of the spring legs without the hinge pin upon actuation of the actuating element, the web preferably has an increasing width in the direction of actuation. The bridge can widen in this direction, for example, wedge-shaped. An actuation axis, along which the actuating element is movable, can be arranged substantially parallel, in particular coaxially, or transversely to the pivot axis.

For a simple operation by an operator, the actuating element is coupled with a, in particular easily accessible, operating element in a further development. In this case, an operating axis, along which the operating element is movable, can be arranged substantially parallel, in particular coaxially, or transversely to the actuating axis.

To support the toilet seat set during a pivoting movement, the toilet seat hinge in a preferred development on at least rotationally fixed to the adapter piece connected damping device. The damping device is preferably arranged with the adapter piece along the pivot axis.

In particular, if it facilitates the operation by an operator, the damping device is at least partially penetrated by the actuating element in a development.

Preferably, the damping device is formed via a cylinder and a rotary piston rotatable therein, which is particularly penetrated by the actuating element.

A toilet seat assembly according to the invention has a toilet seat and a toilet lid, which are pivotally connected via at least one toilet seat hinge, which is formed according to at least one of the aspects of the foregoing description and attachable to a ceramic.

In a variant of the toilet seat set is the actuating element or the actuating elements of the toilet seat joints, based on a central axis of the toilet seat set, operable from the side outside the toilet seat set. This proves to be comfortable for the operator. In a variant of this, the actuating element or the actuating elements can be actuated starting from the central axis. Here lies the advantage that design relevant, laterally arranged outside outer surfaces of the toilet seat set are not affected by the actuator.

The variants then have an actuating direction rotated by about 180 ° to the other variant. This in turn requires that the locking elements of the two variants are arranged mutually rotated by about 180 °.

In particular, in a variant in which the actuating element is arranged on a remote from the locking element end portion of the toilet seat hinge, the toilet seat hinge on a through-hole, which is penetrated by an actuating pin of the actuating element towards the locking element. The passage recess preferably extends along a neutral fiber of the toilet seat hinge, in particular the adapter or a damper or damper piston, in particular along its central axis, for example the pivot axis.

Preferably, the toilet seat has two approximately similar, arranged symmetrically to the central axis of the toilet seat, toilet seat according to the invention. These are both operable either from the side of the toilet seat set or starting from the central axis of the toilet seat set. Of course, mixed forms are also conceivable.

In a further development of the variant, in which, starting from the central axis is actuated, the toilet seat has a arranged between the toilet seat joints control unit - also called "barrel" - on which a transversely to the pivot axis palpable / operable control element is provided that is coupled via a coupling device of the operating unit with the actuating elements of the toilet seat joints.

In the following, two embodiments of a toilet seat set according to the invention with a toilet seat hinge according to the invention are explained in more detail with reference to eight drawings. Show it: 1 shows an embodiment of a toilet seat set in a partial section, Figure 2 shows a first embodiment of a toilet seat hinge of the toilet seat set according to Figure 1 in a vertically-guided longitudinal section,

FIG. 3 shows the toilet seat hinge according to FIG. 2 in a horizontally guided longitudinal section,

FIG. 4 shows the longitudinal section according to FIG. 3 in a rotated representation,

FIG. 5 is an enlarged view of the toilet seat hinge according to FIGS. 2 to 4 with locked release position;

FIG. 6 shows a second exemplary embodiment of a toilet seat joint in a vertically sectioned perspective view,

Figure 7 shows the toilet seat hinge according to Figure 6 in a horizontally guided longitudinal section, and

Figure 8 shows the toilet seat hinge according to Figure 6 and 7 in a further horizontally guided longitudinal section.

In Figure 1, a toilet seat set 1 with a toilet lid 2 and a toilet seat 4 is shown. For reasons of clarity, only one half of the toilet seat set 1 and a part of a ceramic 6 is shown. The toilet seat set 1 has a toilet seat hinge 8, via which both the toilet lid 2 and the toilet seat 4 are pivotally connected to the ceramic 6. Not shown is another toilet seat hinge 8, on which the toilet seat set 1 is mounted on the ceramic 6 beyond a central axis. The toilet seat hinges 8 are designed such that the toilet seat set 1 can be pivoted from its illustrated closed position by more than 90 ° about a pivot axis 10 in an open position in which the toilet lid 2 and / or the toilet seat. 4 abut against a stop.

Figure 2 shows the toilet seat hinge 8 of Figure 1 in a guided vertically through the pivot axis 10 longitudinal section AA. The toilet seat hinge has an adapter 12 with a substantially cylindrical portion 14 on which according to Figure 1, the toilet lid 2 and the toilet seat 4 are pivotally mounted about the pivot axis 10. The cylindrical portion 14 has a stepped cylindrical recess 16 with radially inwardly axially extending ribs 18. In the recess 16, a rotary damper (not shown) can be used, which has a rotary piston which is in positive engagement with the toilet Cover 2 or the toilet seat 4 can be brought. In this way, lowering movements of the toilet lid 2 and the toilet seat 4 are comfortably damped.

Approximately in the middle of the adapter 12 is radially constricted. The radial constriction 20 is followed by a partially cylindrical adapter section 22 which is approximately perpendicular to the

Swivel axis 10 has a receptacle formed as a blind hole 24. In the receptacle 24, a hinge pin 26 is inserted from the ceramic side and abuts with a flattened tip 28 on a base 30 of the receptacle 24. The partially cylindrical portion 22 has a section A-A substantially L-shaped recess 32 whose short leg terminates in the vertical direction approximately with the pivot axis 10. In the recess 32 a partial cylindrical portion 22 complementary insert 34 is inserted, which is traversed by a passage receiving 36 in alignment with the receptacle 24. Accordingly, the hinge pin 26 passes through the passage receiving 36 and then immersed in the receptacle 24 a. In the direction of the pivot axis 10 of the partially cylindrical portion 22 terminates flush with the insert 34.

Both are encompassed radially by a sleeve 38, which is pushed onto the insert part 24 and the part-cylindrical portion 22 in the direction of the pivot axis 10 on the two components. Close to the constriction 20, the part-cylindrical section 22 has radially outwardly raised latching lugs 40, which are latched into corresponding latching recesses of the sleeve 38. In this way, the sleeve 38 is secured against withdrawal from the adapter 12. The part-cylindrical portion 22 has a radially outwardly extending shoulder 46 with which in abutment is a radially inwardly extending shoulder 48 of the sleeve 38. In this way, a further sliding of the sleeve 38 is prevented on the adapter 12.

The hinge pin 26 has, in a region of the passage receiving means 36 close to the ceramic, a circumferential groove 42, into which an O-ring 44 is inserted. In this way, an interior of the sleeve 38 and the components disposed therein are sealed against ingress of dirt or aqueous solutions from the outside, whereby contamination and wear is prevented. On the end section facing away from the adapter 12, the sleeve 38 has a passage recess 50, which is penetrated by an actuating element 52 designed as a knob. The actuating element 52 has a substantially cylindrical basic shape, which is slightly tapered in the direction of an actuating surface 54. For better operation and to increase the grip, the actuating surface 54 is concave.

In the direction of an interior 56 enveloped by the sleeve 38, the actuating element 52 extends into the interior 56 with an actuating pin 58 stepped in an L shape. A long leg 60 of the actuating pin 58 dives into a pocket 62 milled out in the part-cylindrical section 22 and bounded by the insert part 34. Through the interaction of the long leg 60 with the pocket 62, the actuator 52 is guided axially along the pivot axis 10 during actuation.

To hold the actuator 52 in an unactuated starting or Verrastungs- position, the actuating pin 58 is encompassed by a compression spring 64, on the one hand on an approximately coaxial with the actuating pin 58 in the actuator 52 formed groove 66 and on the other hand on the part-cylindrical portion 22 and Insert 34 is supported.

A maximum stroke H of the actuating element 52 results when an adapter-side end face 68 comes into contact with an end face 70 of the insert part 34 and the part-cylindrical section 22.

A short leg 72 of the actuating pin 68 forms an approximately transversely to

Pivoting axis 10 aligned actuating surface 74, via which a resiliently formed locking element 76 with an actuating force, which is symbolized in Figure 2 by an applied to the actuator 52 arrow, is resilient. The locking element 76 has spring legs 78, which are locked in accordance with Figure 2 in a groove-like circumferential recess 80 on the hinge pin 26, provided that the actuator 52 is in its unactuated Verrastungsposition shown in Figure 2.

FIG. 3 shows a section BB which is guided in a horizontal direction through the pivot axis 10 according to FIG. Good to see the above the peripheral recess As a further piece of information about the figures shown so far, a more detailed insight into the mechanism for latching and releasing the toilet seat hinge 8 on the hinge pin 26 results from FIG. 3. The latching element 76 has a central connecting section designed as a ring spring is, and which extends annularly on both sides of the pivot axis 10. According to FIG. 2, the annular spring has approximately three turns. From the annular spring portion extend on both sides of the pivot axis 10 spring leg 78 laterally outward until they are in the region of an inner wall of the partially cylindrical portion 22 back to the hinge pin 26. Looking at Figure 2 and Figure 3, it can be seen well how the spring legs 78 engage in the circumferential recess 80. According to FIG. 3, the circumferential recess 80 lies somewhat below the sectional plane of the section BB and is therefore concealed by the hinge pin 26. Due to the cut, the long leg 60 of the actuating pin 58 according to Figure 2 is also cut away and only the short leg 72 can be seen.

The actuating element 52 has laterally on both sides of the actuating pin 58 two arms 81, which extend from the end face 68 in the direction of the pivot axis 10 toward the hinge pin 26. They are adapted to slip on actuation of the actuating element 52 on both sides of a circumferential surface 82 of the hinge pin 26 until the stroke H is reached.

The arms 81 each have laterally on the outside a latching lug 84, which acts as an abutment of the spring force of the compression spring 64 during its latching (in said latching position) and defines an axial position of the actuating element 52 in said latching position. Further, each arm 81 has at its end portion a wedge-shaped portion 86 which is provided for fixing the operating member 52 in a release position in which the spring legs 78 are lifted from the peripheral recess 80. At the sections 86, a first wedge surface 88 is arranged laterally outwardly in each case. Laterally in each case a second wedge surface 90 is provided at the portions 86. The wedge surfaces 88, 90 are aligned at an obtuse angle with respect to a central axis of the actuating element 52, which corresponds to the pivot axis 10. FIG. 4 shows the longitudinal section according to FIG. 3 in a representation slightly rotated about the pivot axis 10. It can be clearly seen that in the Verrastungsposition the actuator 52 of the compression spring 64 with its locking lugs 84 to stop with a shoulder of the partially cylindrical portion 22 of the Adapter 12 is brought.

A change between the Verrastungsposition shown in Figures 2 to 4, in which the spring legs 78 engage in the peripheral recess 80 and thus define the adapter 12 on the hinge pin 26, towards a locked release position in which the spring legs 78 permanently release the peripheral recess 80, is explained with reference to FIG. According to FIGS. 3 and 5, the spring legs 78 are each supported on an adapter-fixed support 92 in the form of a bolt. Starting from the latching position according to FIG. 3, an actuating force is exerted on the actuating surface 54 by the operator, by means of which the actuating element 52 moves along the pivot axis 10 in the direction of the hinge pin 26. This is done initially against the spring force of the compression spring 64. From a stroke that reduces approximately the stroke h reduced by the thickness of the spring leg 78, the actuating surface 74 comes into contact with the connecting portion of the locking element 76, which is designed as a ring spring portion. From this point on, the operator must use the actuating element 52 to increase the spring force of the annular spring section to increase the actuating force 52 in the direction of the hinge pin 26. Referring to FIG. 3, it can be seen that the arms 81, with the commencement of actuation, slide on the peripheral surface 82 of the hinge pin 26 with their portions 86.

With the moment in which the actuating surface 74 is in contact with the connecting portion of the locking element 76 and is pushed further in the direction of the hinge pin 26, due to the deflection of the spring leg 78 on the supports 92, the lifting of the spring leg 78 from the peripheral recess 80 begins Operator will press the actuator 52 with the stroke H of Figure 3 to the stop of the end face 70. Already from a stroke h, the arms 81 surround the peripheral surface 82 of the hinge pin 26 as shown in FIG. The spring legs 78 are at this moment completely lifted from the peripheral recess 80, whereby the hinge spine 26 is released. This is called the release position. In order for this release position to be sustained, the sections 86 are in this state with their wedge surfaces 88, 90 on the one hand the adapter 12 in operative connection and on the other hand with the peripheral surface 82 of the hinge pin 26 in abutment. The first wedge surfaces 88 are in each case in contact with an adapter-fixed support member 94, which is curved in each case toward the section 86 and is elastically deformable. In this way, the portion 86 may slide in between the hinge pin 26 and the support member 94, deform the support member 94 laterally outwardly until the latter snaps back and engages the first wedge surface 88. In this way, the portion 86 between the hinge pin 26 and the support member 94 is clamped. In the release position thus the wedge surfaces 88, 90 hold the actuator 52 against the spring forces of the annular spring portion of the locking element 76 and the compression spring 64. The introduction of force of the sections 86 on the peripheral surface 82 and the support members 94 is symbolized by means of small arrows in FIG.

In the unlocked position locked in this way, it is easy for the operator to remove the toilet seat hinge 8, or the toilet seat set 1, from the hinge pins 26, for example for the purpose of cleaning or replacement. The advantage here is that the actuator 52 instead of as known from the prior art, no longer needs to be pressed permanently, but is locked in the release position as shown. The operator can therefore concentrate entirely on the removal of the toilet seat set 1 of the ceramic 6 and thus can easily avoid tilting.

Figure 6 shows a second embodiment of a toilet seat hinge 108 in a vertically sectioned, perspective view. For the sake of simplicity, the following description is limited to the differences from the first exemplary embodiment of the preceding figures, wherein components which are the same over the exemplary embodiments are provided with the same reference numerals. The section CC according to FIG. 6 is guided through the longitudinal axis of the hinge pin 26 according to FIG. In Figure 6, the known from the previous embodiment sleeve 38 is removed in the illustration, whereby a modified against the above-described adapter 12 adapter 1 12 is visible. In the receptacle 24 of the hinge pin 26 is used in the manner already described. In the adapter 1 12, two are in the direction of the pivoting axis 10 and in each case laterally to the receptacle 24 extending shafts 96 and 98 are formed. In the first slot 96, the spring legs 78 of the locking element 76 are forcibly taken. Accordingly, arms 181 of an actuating element 152 are positively received in the second shaft 98. From Figure 6 shows that the locking element 76 engages with its spring legs 78 in the circumferential recess 80 of the hinge pin 26, which corresponds to the Verrastungsposition of the hinge joint 108. Notwithstanding the first embodiment, the receptacle has a circumferential collar 25 on its opening facing the ceramic. This is used for the axial fixing of the sleeve 38 (not shown) in the direction of the pivot axis 10. For this purpose, the sleeve 38 slides during assembly over the collar 25 until the collar 25 in a recess of the sleeve 38, which is enforced by the hinge pin 26 (see 2), snaps into place. For a better understanding, the further description is made with reference to FIGS. 7 and 8.

Figure 7 shows a horizontal section, as it is carried out according to Figure 6 along the cutting plane DD. Accordingly, the hinge pin 26 is cut at its free end portion 82 above the peripheral recess 80. At the free end portion 82, the arms 181 can slide tangentially and be spread upon actuation of the actuating element 152 in the direction of the actuating axis 10. Illustrated in FIG. 7 is the latching position of the actuating element 152 (full-line representation) and the release position of the actuating element 152 (dashed representation of the spread-out lower arm 181). It can be seen from FIG. 7 that the arms 181, just like the arms 81 of the preceding embodiment, have a section 186 which is substantially wedge-shaped with respect to the actuating direction 10. Each section 186 in this case has a first wedge surface 188 which can be brought into contact with the adapter 1 12, more specifically a resiliently configured support element 194 from the adapter 1 12 releasable adapter section 13. The adapter portion 13 extends according to Figure 6 spangenformig in a partially circumferential circumferential groove of the adapter 1 12. By removing the adapter portion 13, for example, the simple removal of the locking function described here is possible. A second wedge surface 190 is engageable with the free end portion 82 of the hinge pin 26. This position of the arms 181 is shown in dashed lines in Figure 7 below. From the latching position shown in full line in FIG. 7, the actuating element 152 can be pushed to the right along the actuating direction 10 in FIG. 7, as a result of which the arms 181 slide tangentially on the free end section 82 of the hinge pin 26. Due to the elastic deformability of the support elements 194, they are deformed laterally outwardly by the section 186 of the arms 181 supported on the free end section 82, so that the sections 186 can slide between the hinge pin 26 and the support elements 194. If the first wedge surface 188 engages behind a corresponding abutment surface of the support element 194, then the support elements 194 snap back laterally inwards and lock the actuation element 152 in the release position shown in dashed lines. It can be clearly seen in FIG. 7 that the arms 181 in the release position (dashed) do not engage the hinge pin 26 beyond its equator (corresponding to the section line CC). The holding of the actuating element 152 in the release position thus takes place only due to the clamping between the hinge pin 26 and the support elements 194 and not due to rear grip.

FIG. 8 shows the toilet seat joint 108 in a section EE, as defined according to FIG. Accordingly, the cut runs approximately at the upper edge of the first shaft 96, so that the view is released on the latching element 76 with its spring legs 78 forcibly guided in the circumferential recess 80 and in the first shaft 96. It can be clearly seen that compared with the first Embodiment no compression spring between the actuator 152 and the adapter 1 12 is provided. The necessary spring force which restores the actuating element 152 in its non-actuation in its starting position corresponding to the Verrastungsposition, is applied exclusively in the present embodiment, the elastic locking element 76. This represents a device simplification compared to the first embodiment. Furthermore, the adapter 1 12, unlike its predecessor, on the first slot 96 in two sections 96a and 96b splitting ridge 100 on. On him free end portions of the spring legs 78 can slide on actuation of the actuating element 152 in the direction from the Verrastungsposition shown in the release position. In addition, the web prevents 100 in the disassembled state of the toilet seat hinge 108, that is, when the hinge pin 26 is not seated in its receptacle 24, the pivoting of the spring leg 78 into the receptacle 24 into it. This ensures that none of the spring legs 78 obstructs the receptacle 24, and the insertion of the coulter Nierdorns 26 is possible at any time. Similar to the first embodiment, the locking element 76 is supported with its two spring legs 78 on supports 192, between which is arranged by the actuating pin 158 of the actuating element 152 acted upon by the actuating force connecting portion. The supports 192 are configured as extending approximately along the pivot axis 10 extending towards the receptacle 24 ribs. Their angle is somewhat stronger than the engagement of the spring legs 78, so that the latter can still rest freely against the base of the circumferential recess 80 in the latching position.

Disclosed is a toilet seat hinge for attaching a toilet seat set to a ceramic with an adapter piece for receiving a hinge pin. In this case, a resiliently designed and supported on at least one support locking element is provided which has at least one spring leg which is immersed in a Verrastungsposition in a circumferential recess of the hinge pin, and which via an actuating element in a release position in which it is lifted from the peripheral recess, is elastically deformable. According to the invention, the locking element in the release position by means of the hinge pin, so if this is used in the recording, festleg- or lockable.

Disclosed is still a toilet seat set with at least one such toilet seat hinge.
