Definitions

  • the invention relates to a toilet cover assembly
  • a toilet cover assembly comprising a seat pivotally con ⁇ nected to a bracket about a horizontal axis, said bracket provided with fastening parts for fastening the bracket to a toilet bowl and at least one damping means for damping the movement of the seat from a raised to a lowered position
  • a housing member accommodating a fluid compartment filled with a damping fluid and a partition wall member arranged movably in the housing and dividing the fluid compartment into two chambers interconnected by means of a leakage flow passage, and either the housing member or the partition wall member being fixedly connected to the bracket and the other member being operationally interconnected with the seat by means of a coupling so as to be moved relative to the other member at rotation of the seat.
  • US-A-5.193.228 and US-A-5.255.396 both disclose a toilet cover assembly of the above type, in which the bracket is formed of two separate bracket halves, each provided with a damper.
  • the damper of one of the bracket halves is adapted to dampen the movement of the seat, while the damper of the other bracket half is adapted to dampen the movement of the cover.
  • Both dampers are formed so as to perform damping at rotation in one direction, while the damping is eliminated or considerably reduced at rotation in the opposite direction.
  • the two bracket halves can be arranged only in one manner on the toilet bowl relative to the seat and the cover, the dampers thereof otherwise operating in the opposite direction that the intended, if the two bracket halves are interchanged.
  • DE-C2-37 01 720 a toilet cover assembly of the above type, which, however, does not comprise means for removing the seat from the bracket formed of two separate bracket halves.
  • Most toilet bowls are provided with two holes to be used when fastening the bracket of the toilet cover assembly thereto.
  • the position of the holes varies considerably from a toilet bowl of one manufacturer to a toilet bowl of another manufacturer, for which reason it is desirable to arrange the fastening parts of the bracket offset laterally relative to the axis of rotation of the seat and/or the cover such that they have differing positions when the bracket is rotated 180°, whereby the bracket can be mounted on the greatest possible number of different types of toilet bowls with a correct position of the seat and cover relative to the bowl.
  • the object of the invention is to provide a toilet cover assembly of the above type allowing the bracket to be mounted in two positions rotated 180° relative to each other about a vertical axis.
  • the toilet cover assembly according to the invention is characterised in that the partition wall member is adapted to be moved relative to the housing member in two opposing directions from a neutral position corresponding to the raised position of the seat to an end position corresponding to the lowered position of the seat, in which the volume of the first fluid chamber has been increased, while the volume of the second fluid chamber has been reduced, and in which fluid passages are provided which at least when the partition wall member is slightly distanced from its neutral position connect a first fluid chamber with a second fluid chamber in any position of the partition wall member, a valve further being provided in said fluid passages essentially preventing fluid from flowing from the first fluid chamber to the second chamber when the partition wall member is moved from its neutral position to an end position in said one fluid chamber in both said opposing direc- tions, but allowing flow in the opposite direction at movement back to the neutral position.
  • valve in the fluid passage between the two chambers prevents fluid from flowing through said passage from the chamber whose volume now is reduced to the chamber whose volume now is increased, whereby fluid can only flow between the two chambers through the leakage flow passages such that the movement is dampened.
  • valve in the passage between the two chamber once more allows fluid to flow through the passage, whereby the movement back to the neutral position takes place essentially without damping.
  • the move ⁇ ment of the seat from its raised position to its lowered position is dampened regard- less of in which direction the seat is turned, whereby it is possible to rotate the bracket 180° about a vertical axis and still obtain the intended damping of the seat from its raised to its lowered position.
  • a toilet cover assembly further comprising a cover pivotally connected to the bracket about same axis as the seat, said bracket being provided with a damper for damping the rotation of the cover from a raised to a lowered position
  • a housing member having a fluid compartment filled with a damping fluid and a partition wall member movably arranged in the housing member and dividing the fluid compartment into two chambers interconnected by means of a leakage flow passage
  • the partition wall member can be adapted to be moved relative to the housing member in two oppos ⁇ ing directions from a neutral position corresponding to the raised position of the cover to an end position corresponding to the lowered position of the cover, in which the volume of one of the fluid chambers has been increased, while the volume of the other fluid chamber has been reduced, and two fluid passages are provided which at least
  • the two fluid passage can be formed as a common connecting passage and the valve for preventing fluid flowing therethrough is activated by means of the pressure in the fluid chamber whose volume is reduced when the partition wall member is moved in the direction away from its neutral position.
  • the valve prevents flow through the connecting passage when the partition wall member is moved from its neutral position towards one of the two end posi ⁇ tions, whereby said movement is dampened, but allows free flow through the connecting passage when the partition wall member is moved from one of the two end positions towards the neutral position, whereby essentially no damping of the movement occurs.
  • the common connecting passage can be formed across the partition wall member.
  • valve when the partition wall member is pivotally arranged relative to the housing member the valve can comprise a valve member arranged in an essentially axially extending control passage extending across the common connecting passage and the end of the control passage facing away from the common connecting passage co-act with portions of the housing member so as to provide a communication with the fluid chamber towards which the partition wall member is turned at rotation away from its neutral position.
  • the valve member When the partition wall member is turned from the neutral position towards one of the respective end positions, the valve member is on one side subjected to the pressure in the chamber whose volume now is reduced and on the other side subjected to the pressure in the common connecting passage. As the highest pressure exists in the chamber whose volume is reduced, the valve member is displaced to close the connecting passage, whereby the fluid is only able to flow from the chamber whose volume is reduced to the other chamber through the leakage flow passage, whereby the movement is dampened.
  • the pressure in the common connecting passage exceeds the pressure in the chamber whose volume is increased, allowing a free flow of fluid through the connecting passage, whereby no essential damping occurs.
  • the partition wall member may comprise a tubular central part having a circular external cross-section and extending co-axially with the axis of rotation and a vane extending radially and axially therefrom, the common connecting passage extending across the tubular part and the control passage being formed of the interior of the tubular part.
  • control passage may be provided with an aperture extending radially through the wall of the tubular part in the portion closest to the vane, where the vane may have an axially extending recess to receive a circular ring sector shaped projection on the end wall of housing, said projection adapted to cover the aperture to the interior of the control passage when the partition wall member is in its neutral position and adapted to open the fluid connection thereto when the partition wall member is rotated away from said position.
  • the intended opening between the chamber whose volume is reduced and the control passage is provided in a particularly simple manner when the partition wall member is in a rotated position relative to the neutral position.
  • valve member in the control passage is maintained spaced apart from the end aperture by means of a spring means preload ⁇ ing it into the closing position across the common connecting passage, the valve member in the area exposed to the respective fluid chambers having surface portions dimensioned so that the fluid pressure acting thereon overcomes the preloading force of the spring means as a result of a reduction of the pressure in the fluid chamber communicating with the end of the valve member 69 facing the end wall of the housing member and thus allows flow through the connecting passage when the partition wall member is rotated back towards its neutral position.
  • valve member Due to the spring-loading of valve member towards the closing position in which it closes the common connecting passage, said member is very quickly moved into the closing position, if the seat or the cover is released while being moved from the lowered to the raised position, whereby the downward movement of the seat and the cover is quickly dampened.
  • the end of the tubular, central part of the partition wall member immediately adjacent the end wall of the housing member may be received in a circular recess in the said end wall.

Abstract

L'invention porte sur un ensemble siège-couvercle pour cuvette de WC comportant un siège (1) monté pivotant sur un support (3) et un amortisseur amortissant le mouvement du siège (1) lorsqu'il passe de la position levée à la position abaissée. L'amortisseur se compose d'un boîtier (23) comportant un compartiment rempli d'un fluide, et une cloison pivotante (25) divisant le compartiment en deux chambres et pouvant se déplacer dans deux directions opposées, depuis une position neutre jusqu'à une position terminale et inversement. Le compartiment (39) comporte deux orifices (65, 66) reliant les deux chambres (67, 68) quelle que soit la position de la cloison (25). Un clapet (69) posé dans les orifices (65, 66) empêche pratiquement l'écoulement du fluide d'une première chambre vers la seconde lorsque la cloison (25) se déplace vers l'une des positions terminales dans de la première chambre (67), mais le permettant lors que la cloison revient à sa position neutre.
