FR2884842A1 - Hand sink for water closet, has part formed as adaptor to be fixed on flush tank using multi-purpose retainer and another part formed as hand sink basin, equipped with faucet and exhaust, forming cover for hand sink - Google Patents

Abstract

The hand sink has a part formed as an adaptor (1) to be fixed on a flush tank (2) using a multi-purpose retainer and receiving the control from a closing control mechanism with a double trigger function. Another part is formed as a hand sink basin (10) that is equipped with a faucet (9) and an exhaust (11) and forms a cover for the hand sink. Two holes are provided at the base for installing the fixing system.

Description

The present invention relates to a sanitary device consisting of 2 sub

  sets intended to be positioned, replacing the cover, in the upper part of the cistern of a standard toilet to associate a wash-stand.

  Indeed, in many homes today, for reasons of space saving or rapid rehabilitation, the toilet is still not equipped with a washbasin associated with the toilet This situation is less and less consistent with our growing need for hygiene: need for guests to find a water point, etc ...

  The renovation of the site by adding an individual hand-basin, if it is possible as this room is often cramped and evacuations inaccessible, requires the use of a man of the art and a significant cost that often repels.

  Many solutions have been devised to combine washbasins and cistern, but all suffer from the same problem of requiring the design / implementation: - new tanks paired with the selected solution 20 - new automatic filling mechanisms with predetermined setpoint - new hunting water shutoff control mechanisms As many industrial and economic brakes that eliminate the viability of such solutions.

  The object of the present invention is to create a handwashing device adaptable to the existing toilet and having the following advantages for the industrial and the particular: 3o - Very simple and quick to install for any handyman - - Not requiring replacement the hunting tank because it is fully adaptable to most of these thanks to a versatile system of adjustable lateral attachments - not requiring a complex design / implementation, since only using the most common filling and filling mechanisms in mass-market stores - saving water as the water drain from the washbasin contributes to filling the tank and the shutter control mechanism is double triggering 3L-6L for better consumption management Figures 1-2-3 show the different steps of the embodiment Figures 4 - 5 - 6 show a section of the device thus formed with different Possible designs This device is thus constituted as follows (FIG. 4). A first hollow part, called the adapter (1) FIG 2 and 4 made of ceramic or resin and whose general shape, annular, recalls that of a hunting tank of low height and is constituted as follows: Its dimensions at its base are slightly greater than the dimensions 15 found at the top of the standard hunting tanks (18 cm X 42 cm approximately) Its bottom is flat on a few centimeters at its periphery (About 5 cm) to ensure a stable seat when positioned on the tank (2) 2 holes of small diameter (about 8mm) made in low position on both sides of these sides allow to install the fixing mechanisms ( 4) or (12).

  2 holes of greater width (about 4 cm), offset, at mid height and symmetrical front and rear face to position the control button cable-controlled shutter mechanism The adapter, thus produced, is perfectly symmetrical and allows an internal arrangement indifferent to a lateral water supply by the left or the right.

  - Once positioned in place of the tank cover, the adapter is secured to the latter through the fastening system (4) .II consists of a threaded shaft fixed on the body of the adapter which immobilizes to its turn with 2 nuts a metal blade whose threaded end receives a screw equipped with a rubber pad that presses on the inner face of the tank, thus allowing a great possibility of lateral adjustments (type greenhouse joint building).

  Another method of attachment (12 FIG 5) simpler implementation is possible using a flexible jumper consisting of a thin sheet of metal which is crushed by a nut to pinch the two parts.

  In all the embodiments, it is desirable to equip the parts in contact with the ceramic rubber buffers to avoid mechanical stresses.

  - The push button (5) of the cable control of the water shutter mechanism (8) initially removed from the cover is installed on the front of the adapter (1). See FIG 1-2-3 The system is intended to work with this type of mechanism that allows to deport its control without lo particular functional stress.

  If it is not installed basic, replacement is necessary but without difficulties, as this type of mechanism is widespread because of its universal and inexpensive.

  In addition, it generally offers a dual control 3L-6L which participates 15 to save water.

  - A tee-shaped plumbing piece (3) made of copper or plastic extended with a stainless steel hose (6) is placed in series between the WC stopcock and the tank filling mechanism.

  The dimensions of this tee will be such that they will not change the overall dimension of the plumbing outside the tank and will deport the filling mechanism as little as possible to avoid interfering with the shutter mechanism.

  This arrangement is compatible with a horizontal float mechanism (FIG. 5) provided that it supports the lateral offset required by the installation of the tee (3).

  This assembly is also compatible with a flush tank with water inlet from below. For this purpose it will suffice to add an extension (13 FIG 6) at the end of the initial hose (6) to reach the tee (3) positioned upstream of the filling mechanism in the lower part (14 FIG 6) In all cases, if a replacement is necessary, the use of a filling mechanism to predetermined set by vertical float (7) is preferred for its small size.

  Its spread in supermarkets is also the most widespread.

  - The second important part of the invention is the so-called bowl cover piece (10). It is made of ceramic or resin, it has a hollow bowl shape with a peripheral shoulder that makes it a cover adapted to the adapter (1).

  It is totally symmetrical for an assembly following previous arrangements.

  It includes a reservation to install a conventional faucet (9) and a plug connected to a flexible pipe opening into the tank below.

  An orifice in the upper part of the water receiving zone (16) serves as overflow safety in the reservoir below if necessary. The judicious length of the hose (6) allows sufficient latitude for easy clamping. on the tap (9) before the final repositioning of the bowl cover on the adapter.

  For this solution to be exploitable, all the operations described above (FIG 1-2-3) must be achievable by everyone, quickly and at a reasonable cost.

  This solution is only a palliative to more conventional solutions to be taken into account upstream when possible.
