Description:
Fastening mechanism for a toilet seat

The invention relates to a fastening mechanism for a toilet seat, comprising a bearing block attachable to the toilet bowl with two pivots for the toilet seat, and optionally for a toilet cover, which are operatable for a movement between a bearing position, in which the toilet seat is borne, and a release position, in which the toilet seat is removable.

Such a fastening mechanism is known from US patent 3.261.029. The bearing block shown therein is screwed onto the toilet bowl by means of bolts. In the bearing block two pivots comprising gear racks are provided, which are movable to and fro by means of a pinion positioned between both gear racks. In the position in which the pivots are closest it is possible to remove the toilet seat and the toilet cover. Removing the toilet seat and optionally the toilet cover is advantageous with respect to hygienics. As a result it is possible to prohibit any growth of bacteries at the pivot points of the toilet seat and the toilet cover. However, with this known fastening mechanism the problem remains, that dirt may deposit between the toilet bowl and the bearing block, said dirt not or hardly being accessable.

It is an object of the invention to provide a fastening mechanism of the kind referred to above, in which these disadvantages are removed in a very simple, but nevertheless effective way.

Thus the fastening mechanism according to the invention is characterised in that in the release position of the pivots the bearing block is removable from the toilet bowl. If the pivots have been moved towards the release position by an operation thereof not only the toilet seat, and optionally a toilet- cover, may be released from the fastening mechanism, but is it possible to remove the bearing block from the toilet bowl as well. Like this the bearing block itself as well as the contact location between the bearing block and the toilet bowl may be cleaned in an effective way. Thus an extremely hygienic mounting of the toilet seat is obtained, with which undesired dirt deposits and growth of bacteries can

be avoided.

According to a preferred embodiment of the fastening mechanism according to the invention locking means are provided which are movable to and fro while operating the pivots and which cooperate with mounting means provided on the toilet bowl.

Due to such a constructive design no additional steps have to been taken for detaching the bearing block from the toilet bowl, because operating the pivots automatically leads to a displacement of the locking means.

In this respect it is advantageous if, in correspondence with another embodiment of the fastening mechanism according to the invention, the locking means are fixed to the pivots. A displacement of the pivots during operation thereof thus automatically leads to a displacement of the locking means.

In the si pliest embodiment the mounting means provided on the toilet bowl can comprise holes provided in the toilet bowl into which the locking means can grip. However, an extremely firm and reliable mounting of the bearing block is obtained, if the mounting means comprise bolts inserted in mounting holes of the toilet bowl, the bolt heads of which are provided with lateral recesses into which the locking means grip in the bearing position. The bolts are not removed from the toilet bowl. However, their dimensions are that small, that they can not or can hardly lead to accumulations of dirt or the like.

If according to another embodiment of the fastening mechanism according to the invention the recesses and the locking means are correspondingly tapered, a reliable cooperation between the locking means and the recesses is constantly obtained.

Further it is possible, that an operating mechanism iε applied which is activatable by a removable key. Thus it can be prevented that the toilet seat, the toilet cover or even the fastening mechanism can be taken away by unauthorized persons.

Finally it is preferred that the bearing block is already removable from the toilet bowl before the pivots have fully reached their release position. With such an embodiment an operation firstly releases the bearing block from the

toilet bowl without automatically leading to already detaching the bearing block from the toilet seat and optionally from a toilet cover. In such a position it is possible then to entirely remove the fastening mechanism, to which the toilet 5 seat and optionally a toilet cover is still connected, from the toilet bowl. Only after a further operation being carried i out the pivots will reach their release position in which the toilet seat, and optionally a toilet cover, are removable from the bearing block. 10 Hereafter the invention will be elucidated by means of the drawing, in which an embodiment of a fastening mechanism according to the invention is illustrated.

Fig. 1 shows perspectively a toilet bowl, onto which an embodiment of a fastening mechanism according to the 15 invention is applied, and

Fig. 2 shows a section through the fastening mechanism according to line II-II in fig. 1.

Fig. 1 shows a toilet bowl 1 onto which a toilet seat 2 and a toilet cover 3 are mounted. Onto the toilet bowl 1 a 20 bearing block 4 is mounted which bears the toilet seat 2 and the toilet cover 3 through eyes 5 and 6, respectively, connected therewith. Further in fig. 1 a controle handle 7 iε visible, of which the operation will be elucidated by meanε of fig. 2. 25 In the section corresponding to fig. 2 again a part of the toilet bowl 1 is visible, namely the part onto which the bearing block 4 is provided. In a way known per se mounting holes 8 are provided in the toilet bowl. From the top bolts 9 are inserted into these holes, said bolts at their 30 lower side being secured by nuts 10.

The bearing block 4 is hollow and contains internally two slides 11 slideable to and fro. Each slide 11 carries a bearing pin 12 onto which the eyes 5 and 6 of the toilet seat ^ 2 and the toilet cover 3, respectively, are borne.

35 The slides 11 further comprise projecting locking means 13 engaging in corresponding recesses 14 of the bowls 9.

Between the wall of the bearing block 4 and the slides 11 spring means 15 are positioned trying to move the slides towards each other. In the position shown such a motion 40 is obstructed by an operating means 16 which can rotate around an axis 17. In a way not shown further this axis 17 carrieε

the handle 7 shown in f g. 1.

In the position shown in fig. 2 the ends of the operating means 16' are located into centring recesseε 18 in the εlideε 11. In thiε poεition the bearing pinε 12 are poεitioned in a bearing poεition, in which the eyeε 5 and 6 of the toilet seat and the toilet cover are engaged. In this position the locking means 13 further grip into the receεses 14 of the bowls 9. Thus it will be clear that in this poεition the toilet εeat 2 and the toilet cover 3 cannot be removed from the bearing block 4, whereaε the bearing block 4 itεelf neither can be removed from the toilet bowl 1.

If now by operation of the handle 7 the operating means 16 are moved towards the position illustrated in dots in fig. 2 the slides 11 will be moved inwards under influence of the force applied by the spring means 15, such that the bearing pins 12 to some extent release the eyes 5 and 6. Thus the toilet seat 2 and the toilet cover 3 may be removed. However, simultaneously the locking means 13 leave the recesseε 14, εuch that the bearing block 4 too can be removed from the toilet bowl 1.

Instead of the operating mechanism for the bearing pins 12 and the locking means 13 illustrated in fig. 2 several different operating mechanisms are imaginable. For example a pinion can be mounted onto axiε 17, cooperating with gear racks, which are attached to the εlideε 11. Further it is posεible, that pinε are attached to the εlideε 11 extending through εlotε provided in the wall of the bearing block 4, εaid pinε being engageable manually for moving the slides 11 to and fro. In the embodiment according to fig. 2 the spring means 15 load the slides 11 towards the release position. To avoid that the slides 11 move unintentionally towards this release position the ends of the operating means 16 are located in the centring recesses 18. It is imaginable however, that the spring means 15 are replaced by one single εpring means, positioned between both slideε 11 and loading these εlideε 11 towardε their bearing poεition. In such an embodiment by using a correspondingly adapted operating means care should be taken that the slideε 11 are moved towardε each other againεt the εpring load. It iε an advantage of εuch an embodiment that unintentionally releasing the toilet seat 2,

the toilet cover 3 and the bearing block 4, respectively, iε leεε probable.

The locking meanε 13 have a tapered εhape which correεponds with a tapered shape of the recesses 14. As a result a correct centring of the locking means 13 in these recesεes 14 occurε and the mounting ease is increased. Further this leads to a certain clamping, such that the bearing block 4 always will be pushed correctly against the toilet bowl 1. It is conceivable that the operating mechanism is constructed such that the bearing block 4 already can be removed from the toilet bowl 1 before the pivots 12 have fully reached their release position. In fig. 2 such a configuration can be realized in an easy way by slightly lengthen the bearing pins 12, such that they still hold the eyes 5 and 6 when the locking means 13 already have totally disengaged the recesses 14. Like this it is possible to remove the assembly of bearing block 4, toilet seat 2 and toilet cover 3 in its intirety from the toilet bowl 1. If the bearing pins 12 are lengthened in such a way care should be taken that the slides 11 can realize an inward motion large enough to enable releasing the eyes 5 and 6.

Although in the shown embodiment the locking means 13 engage bowls 9 it is conceivable too, that the locking means 13 engage in a hook-like way into holes 8 provided in the toilet bowl 1. However, preferably specially shaped holes εhould be applied therefore, which could negatively influence the universal applicability of the fastening mechanism according to the invention.

Finally it is noted, that the operating handle 7 can be of a releasable type, functioning as a key. If the operating handle 7 is removed it is nearly impoεεible for unauthorised persons to release the bearing block 4 or toilet seat 2, respectively, or toilet cover 3. As a result the fastening mechanism is safeguarded against theft. The invention is not limited to the embodiment described before, which can be varied widely within the scope of the invention.
