Description
Toilet hinge arrangement Field of the Invention The present invention relates to a toilet hinge arrangement for releasably fastening of a toilet cover assembly including a toilet seat and/or a toilet cover to a toilet bowl so that the toilet cover assembly can pivot about a substantially horizontal rotation axis.
The invention is furthermore directed to a dampener as well as a method of assembling such a toilet hinge arrangement.
Background of the Invention In the art it is well-known to provide toilet hinge arrangement which allows the toilet cover and seat to be dismounted from the toilet bowl in order to improve cleaning pro-cedures and thereby increase the hygiene. Furthermore, it is also known in the art to use dampeners whereby it is possible by means of the dampener to delay the motion of the toilet cover and/or seat when closing the cover or seat whereby a relatively slow and noiseless closing of the seat and/or cover is achieved. An example of such a prior art device is illustrated in EP 1532913, which disclose a dampener embedded in a hinge arrangement. The dampener is enclosed in a sleeve, such that the dampener cannot rotate relative to the fastening means to the ceramics (toilet). The opposite end of the dampener is fixed to a ring-shaped eye part being part of the toilet seat or cover.
A common problem, however, is how to assemble these hinge arrangements in a suit-able manner, both from a factory perspective as well as from a maintenance perspective in that it might be desirable to replace one or the other part. In these situations prior art devices do not facilitate disassembling of the hinge arrangements once they are mounted.

A common problem, however, is how to assemble these hinge arrangements in a suit-able manner, both from a factory perspective as well as from a maintenance perspective in that it might be desirable to replace one or the other part. In these situations prior art devices do not facilitate disassembling of the hinge arrangements once they are mounted.
Object of the Invention Consequently it is an object of the present invention to provide an easy to assemble hinge arrangement which may also be disassembled in order to carry out maintenance works such as for example replace the dampener, replace the seat and/or a cover and the like.
Description of the Invention The invention addresses this by providing a toilet hinge arrangement for releasable fas-tening of a toilet cover assembly, including a toilet seat and/or a toilet cover, to a toilet bowl, so that the toilet cover assembly can pivot about a substantially horizontal rota-tion axis, where dampening means are activated for dampening the downward move-ment of said toilet seat and/or cover, said toilet hinge arrangement includes a base member with a lower side adapted to abut the surface of the toilet bowl, where said base member has a shaft member projecting upwards from the base member, said shaft being suitable to releasably engage a hinge part characterised in that the hinge part comprises:
- a dampener, said dampener having a first end rotatable relative to the dampener body, where the rotation of the first end is dampened relative to the body - an engagement part where said engagement part has means for engaging a first end of said dampener;
- a first ring-shaped connection eye of the toilet seat or cover, having an opening such that the ring-shaped connection eye is arranged about the dampener;
- a second ring-shaped connection eye of the toilet seat or cover, having means for engaging the free end of the dampener body in a non-rotatable manner where said dampener is provided with first fastening means adjacent the free end of the dampener body, where said second ring shaped connection eye is provided with means for accommodating and firmly engaging said dampener's first fastening means;
and where said engagement part is provided with second fastening means which second fastening means will firmly engage the first end of the dampener where both first and second fastening means will maintain the dampener in fixed relationship axially along the rotation axis.
Description of the Invention The invention addresses this by providing a toilet hinge arrangement for releasable fas-tening of a toilet cover assembly, including a toilet seat and/or a toilet cover, to a toilet bowl, so that the toilet cover assembly can pivot about a substantially horizontal rota-tion axis, where dampening means are activated for dampening the downward move-ment of said toilet seat and/or cover, said toilet hinge arrangement includes a base member with a lower side adapted to abut the surface of the toilet bowl, where said base member has a shaft member projecting upwards from the base member, said shaft being suitable to releasably engage a hinge part characterised in that the hinge part comprises:
- a dampener, said dampener having a first end rotatable relative to the dampener body, where the rotation of the first end is dampened relative to the body - an engagement part where said engagement part has means for engaging a first end of said dampener;
- a first ring-shaped connection eye of the toilet seat or cover, having an opening such that the ring-shaped connection eye is arranged about the dampener;
- a second ring-shaped connection eye of the toilet seat or cover, having means for engaging the free end of the dampener body in a non-rotatable manner where said dampener is provided with first fastening means adjacent the free end of the dampener body, where said second ring shaped connection eye is provided with means for accommodating and firmly engaging said dampener's first fastening means;
and where said engagement part is provided with second fastening means which second fastening means will firmly engage the first end of the dampener where both first and second fastening means will maintain the dampener in fixed relationship axially along the rotation axis.
With this arrangement is achieved that the various parts of the hinge arrangement are assembled around the dampener and assembled in such a manner that it by means of the engagement means built into the dampener and the engagement part is possible rela-tively easy to disengage and thereby disassemble the entire hinge arrangement.
In a further advantageous embodiment of the invention the engagement part comprises one or more locking surfaces arranged as interior surfaces, where said surfaces engage corresponding surfaces on the first end of the dampener; and where further a bearing surface is provided inside said engagement part, which bearing surface abuts, guides and supports an outer periphery of the dampener body.
By providing locking surfaces in the engagement part to which the first end of the dampener abuts the transfer of force from the cover/seat of the toilet cover assembly is safely transferred to the shaft and base member and thereby to the toilet bowl. Typi-cally, it will be possible to provide relatively large locking surfaces in order to distribute the pressure to as large a surface as possible. Furthermore, the bearing surface for supporting the dampener is also provided whereby the load from the first and second ring-shaped connector eyes will not solely be borne by the locking surfaces and the dampener, but will also be transferred via the dampener body by means of the bearing surfaces to the engagement part and therefore through the base member to the toilet bowl. In this manner the dampener as such is only exposed to a minimum load which decreases wear and tear on this member.
In a further advantageous embodiment the second fastening means are arranged in said one or more locking surfaces.
The second fastening means will typically be resilient means which at the first end of the dampener is pushed into the engagement part which by click-action will engage and lock the dampener in position relative to the engagement part such that it takes a rela-tively large force to withdraw the dampener from the engagement part. In this connec-tion, however, it should be noted that there are no screws, rivets or the like used in order to maintain a fixed relationship between the first end of the dampener and the engagement part, but solely a resilient mechanism which locks and fixates the first end of the dampener relative to the engagement part.
In a still further embodiment of the invention the first end of the dampener is provided with means complimentary to said second fastening means. In this manner it is possible to design a first end of the dampener in such a way that it will possibly interact with the second fastening means and thereby increase the holding force whereby the dampener will be further maintained in a relatively fixed position relative to the engagement part.
In a still further advantageous embodiment of the invention the second ring-shaped connection eye is provided with a closed side, such that said second ring-shaped con-nection eye will be in the shape of a cup, and that a shaft is provided, projecting from the bottom of the cup, where said shaft is adapted to be inserted into a corresponding cavity in the free end of the dampener.
The shaft of the cup serves to help stabilize and guide the dampener.
When using the hinge arrangement according to the invention in order to mount a toilet cover assembly including a toilet seat and a toilet cover usually two toilet hinge ar-rangements are used, namely one in either side of the toilet cover assembly.
In order to create the correct dampening effect, i.e. having dampening of the seat and cover re-spectively, the dampeners in the two assemblies are arranged such that they rotate in opposite directions, but by mounting them in a mirror image manner they will be able to dampen the movement of the seat respectively the cover in the same direction, i.e.
going from a substantially vertical position into a substantially horizontal position.
By providing the shaft projecting from the second ring-shaped connection with a spe-cific cross section it is possible also to provide various dampeners with different cross sections such that it will only be possible to mount a dampener in a second ring-shaped connection eye having the corresponding cross-sectional shape. In practice, circular cross sections are used for left-hand-side hinge arrangements whereas square cross-sectional shapes are used for right-hand-side hinge arrangements. In this manner it is ensured that the correct type of dampener is mounted in the correct side of the toilet cover assembly. Therefore, the cross-sectional configuration of the shaft and the corre-sponding cavity in the free end of the dampener may take any geometric configuration other than the ones mentioned above, i.e. circular or square, such as for example trian-gular, star-shaped or any other suitable shape which provides the same advantages.
In a further advantageous embodiment of the invention the engagement part comprises one or more locking surfaces arranged as interior surfaces, where said surfaces engage corresponding surfaces on the first end of the dampener; and where further a bearing surface is provided inside said engagement part, which bearing surface abuts, guides and supports an outer periphery of the dampener body.

In a still further advantageous embodiment of the invention the second ring-shaped connection eye is provided with a closed side, such that said second ring-shaped con-nection eye will be in the shape of a cup, and that a shaft is provided, projecting from the bottom of the cup, where said shaft is adapted to be inserted into a corresponding cavity in the free end of the dampener.
The shaft of the cup serves to help stabilize and guide the dampener.
When using the hinge arrangement according to the invention in order to mount a toilet cover assembly including a toilet seat and a toilet cover usually two toilet hinge ar-rangements are used, namely one in either side of the toilet cover assembly.
In order to create the correct dampening effect, i.e. having dampening of the seat and cover re-spectively, the dampeners in the two assemblies are arranged such that they rotate in opposite directions, but by mounting them in a mirror image manner they will be able to dampen the movement of the seat respectively the cover in the same direction, i.e.
going from a substantially vertical position into a substantially horizontal position.
By providing the shaft projecting from the second ring-shaped connection with a spe-cific cross section it is possible also to provide various dampeners with different cross sections such that it will only be possible to mount a dampener in a second ring-shaped connection eye having the corresponding cross-sectional shape. In practice, circular cross sections are used for left-hand-side hinge arrangements whereas square cross-sectional shapes are used for right-hand-side hinge arrangements. In this manner it is ensured that the correct type of dampener is mounted in the correct side of the toilet cover assembly. Therefore, the cross-sectional configuration of the shaft and the corre-sponding cavity in the free end of the dampener may take any geometric configuration other than the ones mentioned above, i.e. circular or square, such as for example trian-gular, star-shaped or any other suitable shape which provides the same advantages.
In a still further advantageous embodiment a shim is inserted around the dampener, between the first and second ring-shaped connection eyes, and where the first ring shaped connection eye is provided with an interior recess for accommodating at least part of said shim, and where said shim has an aperture corresponding to the outer shape of the dampener, and furthermore where means for accommodating and transferring rotation from said shim to said second ring-shaped connection.
In a still further advantageous embodiment of the invention a cover is provided where said cover, being in the shape of a cylinder having a closed end, where the interior di-mensions of said cup correspond to the exterior dimensions of said engagement part, where an aperture is provided in the cylinder wall, allowing the shaft of the base mem-ber to engage with the engagement member. The purpose of the cover is partly to pro-vide a nice finish to the toilet hinge arrangement, but also to hide the second fastening means arranged in the engagement part such that tampering or unintended release of the second fastening means and thereby disassembly of the entire toilet hinge arrange-ment is avoided. As it is important to superpose the aperture in the cylinder wall with the cavity in the engagement part into which the shaft of the base member is inserted, alignment means between the engagement part and the cover may be provided such that the aperture provided in the cover is superposed the opening in the engagement part.
The invention is furthermore also directed to a dampener for use in a toilet hinge con-struction as described above where said dampener is particular in that it comprises a first end rotatable relative to the dampener body, where the rotation of the first end is dampened relative to the body, where at least one resilient fastening member is ar-ranged in the outer wall of the dampener body, where said resilient fastening member is biased radially away from the dampeners axis of rotation, and where one or more in-dentations are provided adjacent the distal end of the dampeners first end, where the indentation(s) are suitable for being engaged by engagement means.
Naturally, the special damper mentioned in the embodiment above will make it feasible to utilize the advantages of the invention as described above.
Also the invention is directed to a method of assembling a toilet hinge arrangement as described above in that due to the inventive fastening means of the damper in the toilet hinge arrangement assembling is very smooth and carried out in such a way that very few operations are necessary in order to assemble the toilet hinge arrangement. Fur-thermore, by implementing certain of the features above, a fully automatic assembly may be achieved.

Detailed Description of the Invention In figure 1 is illustrated a toilet hinge arrangement according to the invention. The toilet hinge arrangement 1 will typically be used in pairs such that a toilet hinge arrangement will be provided in each side of the seat/cover as is well known in the art.
The toilet hinge arrangement 1 comprises a base member 2 which in this embodiment by means of anchors 3 may be fastened to a toilet bowl.
For clarity reasons neither the toilet bowl nor the seat or cover are illustrated. The base member 2 is provided with shaft 4, which shaft is inserted in the hinge part 5. As will be explained with reference to figure 2 the base member including the shaft is detachably fastened to the hinge part 5.
The hinge part 5 comprises an engagement part 10, a first ring-shaped connection eye 20 and a second ring-shaped connection eye 30.
Turning to figure 2 an exploded view of the main components of the invention as well as a few details relating to the base member are illustrated. The base member in this embodiment comprises three disc-shaped parts 2', 2", 2" where 2" is a resilient gas-ket interposed between a metal part 2" and the toilet bowl (not illustrated) which is usually made from a ceramic material, whereby the resilient material of the gasket 2"
separates two hard materials. The metal part 2" is provided with a shaft 4 for engage-ment with the engagement section 10 as explained above. In order to detachably attach the hinge arrangement 5 the shaft is provided with a resilient spring 6 and a rubber seal 7 (0-ring). The resilient spring 6 serves to detachably lock the engagement part 10 to the shaft 4 and the rubber ring 7 serves to dampen and also fasten the aperture in the engagement part to the shaft 4. The cover plate 2" may be made from any suitable material and serves to cover the metal part 2" of the base member where also screws may be used in order to fasten the base member to the toilet bowl.
In the exploded view the dampener 40 is visible between the engagement part 10 and the first ring-shaped connection eye 20. The interior diameter 21 of the first ring-shaped connecting eye has a size which accommodates the body 41 of the dampener 40. The first end 42 of the dampener which is rotatable relative to the body part 41 is engaged with the engagement part 10 such that the engagement part 10 such that the engagement part 10 and the first end of the dampener 42 cannot rotate relative to each other. The special click-features of the dampener 40 will be explained with reference to figure 4.
In this embodiment the hinge arrangement 5 includes a shim 50 interposed between the first ring shaped connection eye and the second ring-shaped connection eye.
Turning to figure 3 a cross section through a hinge arrangement 5 according to the invention is illustrated. From the cross section is evident that the shaft 4 is arranged in the engagement part 10 such that the hinge part 5 is in a position illustrated with refer-ence to figure 1. The dampener 40 is engaged in its first end 42 by means 11 which means 11 are biased/urged for firm engagement against the first end of the dampener.
The means 11 are resilient such that as the engagement part 10 comes into contact with the first end of the dampener 42 the means 11 will click into contact with the first end and lock the first end to the engagement part 10. The dampener is provided with means 43 (see figures 2 and 4) complementary to the fastening means 11 such that the first end of the dampener 42 will be maintained in a firm grip/position relative to the en-gagement part 10.
The second ring-shaped connection eye 30 is in this embodiment provided with a side-wall 31 such that the second ring-shaped connecting eye 30 is in the shape of a cup.
From the bottom of the cup projects a shaft 32 into a cavity 44 provided in the free end of the dampener 40 such that the shaft 32 will help to stabilize and guide the dampener 40 relative to the hinge construction 5. In order to ensure that the correct dampener is inserted in the correct side relative to the way the seat and cover shall be mounted the cross section of the shaft 32 and the cavity 44 may be given a particular shape such as for example square as illustrated with reference to figure 4 a circular, oval or any other desirable shape.
Turning to figure 4 a dampener according to an embodiment of the invention is illus-trated. The dampener is provided with means 43 on the first end for engagement with the means 11 of the engagement part in order to fixate the dampener relative to the engagement part 10. Furthermore, flexible resilient first fastening means 45 are pro-vided in the body of the dampener 40 such that as the dampener is inserted into the second ring-shaped connection eye, the fastening means 45 will be triggered and due to the resiliency of the member will expand into a corresponding cavity 46 provided inside the second ring-shaped connection eye. In this manner the dampener 40 will be locked into engagement with the second ring-shaped connection eye 30.
After both the engagement part and the second ring-shaped connection eye have been attached to the dampener the first ring-shaped connection eye will be free to pivot about a pivot axis coaxial with the rotation axis of the dampener without being influ-enced by the dampener as such. Only the second ring-shaped connection eye, for ex-ample attached to a toilet seat or toilet cover will be influenced by the dampener such pie attached to a toilet seat or toilet cover will be influenced by the dampener such that the movement of said toilet seat or cover will be dampened.
Turning to figure 5 an exploded view of a complete embodiment is illustrated where a cover 60 is provided where said cover has a dimension such that it will be able to cover the engagement part 10 and thereby hinder unintended tampering with the fastening means 11 which could cause unintended disassembly of the hinge construction 5.
The cover 60 is provided with an aperture 61 which is use coincides with the aperture 12 (see figure 3) which accommodates the shaft 4.
In fig. 6 is illustrated a view into the interior of the engagement part. The tap 32, in this embodiment having a round cross-section is situated substantially centrally in the cavity for accommodating the dampener 40. The locking surfaces 47 are arranged as part of the interior surfaces in the cavity formed in the engagement part, designed to receive the free end of the dampener body 41. Furthermore the bearing surfaces 48 are also illustrated.

Turning to figure 2 an exploded view of the main components of the invention as well as a few details relating to the base member are illustrated. The base member in this embodiment comprises three disc-shaped parts 2', 2", 2" where 2" is a resilient gas-ket interposed between a metal part 2" and the toilet bowl (not illustrated) which is usually made from a ceramic material, whereby the resilient material of the gasket 2"
separates two hard materials. The metal part 2" is provided with a shaft 4 for engage-ment with the engagement section 10 as explained above. In order to detachably attach the hinge arrangement 5 the shaft is provided with a resilient spring 6 and a rubber seal 7 (0-ring). The resilient spring 6 serves to detachably lock the engagement part 10 to the shaft 4 and the rubber ring 7 serves to dampen and also fasten the aperture in the engagement part to the shaft 4. The cover plate 2" may be made from any suitable material and serves to cover the metal part 2" of the base member where also screws may be used in order to fasten the base member to the toilet bowl.
In the exploded view the dampener 40 is visible between the engagement part 10 and the first ring-shaped connection eye 20. The interior diameter 21 of the first ring-shaped connecting eye has a size which accommodates the body 41 of the dampener 40. The first end 42 of the dampener which is rotatable relative to the body part 41 is engaged with the engagement part 10 such that the engagement part 10 such that the engagement part 10 and the first end of the dampener 42 cannot rotate relative to each other. The special click-features of the dampener 40 will be explained with reference to figure 4.
In this embodiment the hinge arrangement 5 includes a shim 50 interposed between the first ring shaped connection eye and the second ring-shaped connection eye.
Turning to figure 3 a cross section through a hinge arrangement 5 according to the invention is illustrated.

The dampener is provided with means 43 (see figures 2 and 4) complementary to the fastening means 11 such that the first end of the dampener 42 will be maintained in a firm grip/position relative to the en-gagement part 10.
The second ring-shaped connection eye 30 is in this embodiment provided with a side-wall 31 such that the second ring-shaped connecting eye 30 is in the shape of a cup.
From the bottom of the cup projects a shaft 32 into a cavity 44 provided in the free end of the dampener 40 such that the shaft 32 will help to stabilize and guide the dampener 40 relative to the hinge construction 5. In order to ensure that the correct dampener is inserted in the correct side relative to the way the seat and cover shall be mounted the cross section of the shaft 32 and the cavity 44 may be given a particular shape such as for example square as illustrated with reference to figure 4 a circular, oval or any other desirable shape.
Turning to figure 4 a dampener according to an embodiment of the invention is illus-trated. The dampener is provided with means 43 on the first end for engagement with the means 11 of the engagement part in order to fixate the dampener relative to the engagement part 10. Furthermore, flexible resilient first fastening means 45 are pro-vided in the body of the dampener 40 such that as the dampener is inserted into the second ring-shaped connection eye, the fastening means 45 will be triggered and due to the resiliency of the member will expand into a corresponding cavity 46 provided inside the second ring-shaped connection eye. In this manner the dampener 40 will be locked into engagement with the second ring-shaped connection eye 30.
After both the engagement part and the second ring-shaped connection eye have been attached to the dampener the first ring-shaped connection eye will be free to pivot about a pivot axis coaxial with the rotation axis of the dampener without being influ-enced by the dampener as such. Only the second ring-shaped connection eye, for ex-ample attached to a toilet seat or toilet cover will be influenced by the dampener such pie attached to a toilet seat or toilet cover will be influenced by the dampener such that the movement of said toilet seat or cover will be dampened.
Turning to figure 5 an exploded view of a complete embodiment is illustrated where a cover 60 is provided where said cover has a dimension such that it will be able to cover the engagement part 10 and thereby hinder unintended tampering with the fastening means 11 which could cause unintended disassembly of the hinge construction 5.
The cover 60 is provided with an aperture 61 which is use coincides with the aperture 12 (see figure 3) which accommodates the shaft 4.
In fig. 6 is illustrated a view into the interior of the engagement part. The tap 32, in this embodiment having a round cross-section is situated substantially centrally in the cavity for accommodating the dampener 40. The locking surfaces 47 are arranged as part of the interior surfaces in the cavity formed in the engagement part, designed to receive the free end of the dampener body 41. Furthermore the bearing surfaces 48 are also illustrated.
Also partly visible in fig 6 is the shim 50. The shim 50 is inserted around the dampener 40, between the first and second ring-shaped connection eyes 20,30, and the first ring shaped connection eye 20 is provided with an interior recess 52 for accommodating at least part of said shim 50. The shim 50 has an aperture 53 corresponding to the outer shape of the dampener 40, such that the shim may be arranged outside the dampener.
Furthermore, means 54 for accommodating and transferring rotation from said shim 50 to said second ring-shaped connection eye 20 is provided between said shim 50 and the second ring-shaped connection eye 20.
Above the invention has been explained with reference to a particular embodiment, but it is clear to a person skilled in the art that the scope of the invention is only to be lim-ited by the appended claims.
In particular embodiments where the toilet seat and cover are not releasably fastened to the toilet ceramics are also to be contemplated within the scope of the present inven-tion.
