NL8502069A - Water-closet flushing tank - has hook attached to central tube extending through cover to operating button - Google Patents

Abstract

The water-closet flushing tank supplies water in varying amounts. It has an inlet with float valve and a bottom discharge valve opened by lifting the central tube. A hook is attached to the central tube, on which force can be exerted both in the upwards and downwards direction. It extends through the top cover, and engages in a tapped hole in an operating button (7).

Description

u.c. play cabinet · designed to deliver a flush of variable size

Saving energy and therefore also water is the focus of interest · It will therefore come as no surprise that the last Jaran cp submitted a large number of inventions for the distribution of toilets in the field of water consumption in toilets ·

Yet in practice all these thought-ups show how to limit the amount of water · are not noticeably noticeable · The reason for this is not that some of these upsets would not be practical or too expensive · but that it was not allowed according to existing regulations to eposlen less than 9 liter volume · This was the case both in Germany and in the Netherlands in a number of other countries · 15 A fact behind this fact that up to date inventors and patent attorneys so far was not known before and that this also means that a lot of work has been done for nothing

Finally, a provisional DIN standard 20 was published in Germany in 1993, whereby under certain circumstances interruption of the flushing is permitted.

Article 324 of the relevant DIN standard DIN 19542 states: "die Unterbrechung des Spulvorganges 1st zulaseig. Oer aingelaitete Spulvorgang darf jedoch nur durch aine er-25 neute Bstatigung unterbrochen" ·

Bok in the Netherlands has now issued a draft prescription and by hat K.I.W.A. sent for evaluation ·

Also, interruption is now permitted · behind with the explicit stipulation that break should only take place after 3 liters have been flushed · This is also said to have been taken up in Germany · "C- ___ ^ 2.

*. * £ .e.a. did ar tos lead to a need to rethink this whole problem?

It appears that many of the patents already granted do not comply with these news requirements. For example, there are a number of patent questions, including, for example, Offenlegsrungsbericht 2629126 and 2S25531 and 2615882, in which patent application the restriction takes place by applying. a weight on the lever or straight * streaks on the tube operating the valve · 10 Obviously, none of these patent applications * are in accordance with the new regulations, which stipulate that the "single-tracked Spurvorgang nur durch eine arneuta Betatigung unterbrochen warden can "·

Our current patent * eanvrege ia fully in accordance * 15 with the new requirements and the bottom edge follows the technical description thereof ·

It should be noted in the first place that this invention is only tapable on the trays which are held open by a float mechanism until the water has drained from the cistern. These trays can be provided with a lever or operating rod and the valve can opened directly in the vertical direction.

1)

The drawing shows primarily a cistern above the cistern, with the central tube opened by means of a lever.

The news drawing shows the new system indicated above where a hole is drilled in the lid and a hook is attached to the central tube · The straight end of the hook is inserted through the lid and the drsad part is turned into a knob which is of internal screw thread is provided. The operation is now as follows: \ ') 3.

By moving this knob either upwards or downwards, the reservoir (3) can be completely or partially emptied and this discharge can be interrupted at any time. The cistern is also normally equipped with a float (&) that provides new water supply with the help of the valve (2).

There is also an indicator (8), which consists of a float (for example, a cork) .For this float an indicator rod has been inserted, which comes out through the lid and indicates the water level.45 By calibrating this indicator it is easy to check whether the three liters have been flushed before the button is pressed and the discharge is stopped ·

Drawings 2 and 3, which are now described, provide an improvement on the 50 system described so far · In this drawing, no »1 is the indicator provided with a cam on the top * No · 2 is the flush button with a block with two lugs attached ie · Furthermore, nr · 3 is the lid of the cistern, nr. 4 is a plastic plate and nr · 5 is a house 55 that limits the movement of the plastic plate ·

When pulling up the flush button, the small cam passes the holes in the plate and lid, in addition, the large cam moves the plate to the left (see arrow), blocking the small cam. 60 The water now flows out and as soon as the 3 liter amount for which the indicator has been calibrated has been emitted, the cam on the indicator ensures that the slider is bent to the right again · The flush button, then no longer blocked, can be pressed down 65 and the outflow can be accelerated.

The disadvantage of this construction is that it is mounted on top of the lid. This is obviated by the construction shown in drawing 3. In this drawing, the housing is connected to the underside of the lid 70 with the slide, while the indicator float by means of a cord (3) is connected directly to the slider. The operation is as described above, only the release of the small cam, which causes the blocking, is currently not effected by the indicator, but by means of the cord by the downward movement of the float.

It should be noted that the last-described method in particular meets all requirements, i.e. fully in accordance with DIN standard 19542 and can furthermore be operated very simply 80 and very easy to convert by the do-it-yourselfer.

Finally, in drawing no. 4, the construction has been simplified even further, because now the float works directly on the cam on the cam via a hinged element on the 85 operating rod.

Below is a further description of the latter system.

Pos. A is the state where the reservoir is completely filled, the bottom valve 6 is closed, the knob on the 90 operating rod is in the lowest position.

In pos. B the operating rod is pulled out and then pushed so far that the end 7 of the hinged element 3 (pivoting about hinge point 2) engages just below the round conical cam 4.

85 0 2 0 5 $: 5.

95 'The water continues to flow out. Due to the pulling force of the downwardly moving float 5 on the end 7 of the hinge element and the suction force of the outflowing water, the end 7 is released from the cam and the operating rod moves downwards 100 until the bottom valve is closed, so that a partial rinse, which is very precisely adjustable, has been achieved.

For complete flushing, the control rod is pulled out as far as possible and then released. The re-105 reservoir is then automatically completely emptied.
