Abstract

When installing a flushing device in a toilet cistern, it is important to set the flushing device, in particular the standpipe and the surrounding cage to the height of the cistern, after there are no uniform shapes and sizes of cisterns. Known devices provide for this purpose to separate parts to reduce the size or to use clamping devices, but in any case, the standpipe and the cage to assemble separately. This is complicated and laborious, so that the invention should offer a simpler solution, which at the same time adhering to the norms regarding the overflow height always holds. This succeeds through the use of a tensioning scaffold, which the various elements of the standpipe and the cage in addition to the operating state in one connect another state in which the standpipe parts and the cage parts are separated from each other and instead upper elements and lower elements are connected together. In such a state, the standpipe cage unit can be brought into the desired extent by pulling apart or pushed together and returned there to the operating state. The required size ratio is maintained directly.

Description

The present invention relates to a height-adjustable standpipe cage unit comprising a telescoping cage, which consists of an inner cage and an outer cage, and a housed in the cage telescoping standpipe, which consists of an inner standpipe and an outer standpipe.

Such a device is already out of the EP 1 795 660 A2 previously known. This document describes a flushing valve and the associated construction for its operation, which also includes a standpipe and a surrounding standpipe cage. For an adjustment of the height of the standpipe and the cage they can be telescoped and locked by means of latching means in a desired position against each other. In this case, however, it is necessary to set the two parts separately, so that it is also important to set the two parts in the correct ratio to each other. Also the EP 2 146 012 B1 works on such a principle.

In general, the height adjustment is made outside the cistern in the prior art, because the locking means in the installed state are difficult to access. This makes it even more difficult to find the right setting, because an adjustment requires each time an expansion and a new installation.

Another solution is from the DE 602 12 070 T2 previously known, which provides a simple cage, in which a frame can be stretched up and locked on a rack. For a suitable adaptation of the standpipe, however, it is necessary here to separate the standpipe which already has predetermined breaking points for this purpose.

A similar solution in terms of height adjustment can be found in the document EP 1 672 130 B1 , which also assumes a separation of standpipe elements, in the event that it is considered too long.

The EP 2 692 956 B1 comes without a standpipe, but also requires a separate adjustment of the overflow and the cage by a rotary latch is disengaged, moved in height and turned back into engagement.

As a rule, the cage is screwed with a basin element in the bottom of the cistern or fixed there at least by a screw with the cistern. This already largely determines the position of the overall construction in the prior art, the constructions often being at least substantially rotationally symmetrical in order to have the required freedom with regard to the screw connection in the end position.

However, it is time-consuming and tedious to expand the overall construction first again from the cistern to change and then reinstall, or measure them accordingly in advance, so that the present invention is the object of a height-adjustable standpipe cage unit to propose, which is easily adaptable in height in the installed state and in which a separate adjustment of the cage relative to the standpipe can be omitted.

This is achieved by a height-adjustable standpipe cage unit according to claim 1. Meaningful embodiments and further developments can be taken from the subsequent dependent claims.

According to the invention, it is provided that a height-adjustable standpipe cage unit has a telescoping cage, which consists of two concentrically arranged, mutually slidably displaceable parts. An inner cage and an outer cage can in this case be moved against each other so that the foot of the one part is fixed to the bottom of the cistern, while the upper edge of the other part forms the upper end of the construction. In the interior of the cage, a standpipe is arranged, which if necessary can be used simultaneously as an overflow and can be connected to the piston of a flushing device to trigger the flushing process. Here, the standpipe is adjustable in height, since at a higher cage and a higher standpipe is required to optimally utilize the higher design of the cistern.

In order to adjust the standpipe and the cage in the case of a height adjustment simultaneously and to the same extent, the standpipe cage unit on a common telescopic clamping stand, which by means of locking means depending on the detent position, the individual elements of the inner cage, the outer cage, the Inner standpipe and the outer standpipe can connect together in a suitable manner.

For this purpose, two modes of operation can be defined, namely a first detent position, which represents the normal operation, and the second detent position, in which the height of the standpipe cage unit can be adjusted. In the first detent position of the inner cage is connected to the outer cage and thus represents a rigid external structure. At the same time the inner standpipe is connected to the outer standpipe and thus forms a standpipe in the desired length, which within the cage is mounted vertically displaceable for opening and closing the purge valve.

In the second detent position, however, the connections between the inner cage and the outer cage, and between the inner standpipe and the outer standpipe are separated, but at the same time new connections closed by locking, namely the lower cage part with the lower standpipe part, and the upper cage part with the upper standpipe part. In this position, the upper parts are now mounted longitudinally displaceable relative to the lower parts, but fixed to each other, so that now approximately in the mounted state of the standpipe cage unit, the upper parts can be pulled up while the lower parts connected to the bottom of the cistern stay. An end stop in this case preferably prevents complete release of the upper of the lower parts. Is this achieved by pulling the interconnected upper parts of the desired height of the standpipe cage unit, the second locking position is left again and returned to the first locking position by the locking connections between the upper and lower parts dissolved and between the standpipe parts and the cage parts are restored.

In this way, an adjustment of the height of the standpipe cage unit can be performed reversible at any time, especially in the installed state. It only needs to be put into the second locking position, the clamping frame to make an adjustment, a change back to the first detent position puts the standpipe cage unit in the operating state.

To operate the scaffold and make a change in the locking position, the scaffold may have a telescoping rotary shaft, which operates a plurality of locking slide, which can produce and dissolve the different compounds. The locking slide are distributed along the rotation shaft, that in each case a locking slide can be provided in one plane. To operate the locking slide, the rotary shaft in each case at the level of the locking slide actuator lever, which engage in scenes of the locking slide to move them. The actuator lever and the scenes are designed so that the above-described latches are set in the respective associated detent positions of the rotary shaft.

Specifically, this can be solved so that a first locking slide is attached to the outer standpipe and this fixed in the first locking position with the inner standpipe. If the rotary shaft is rotated in the second detent position, so the first locking slide shifts so far back that he remains connected to the outer standpipe, but releases the inner standpipe and dissolves the attachment of the two standpipe parts.

A second locking slide may also be attached to the inner cage and connect with the adjustment of the rotary shaft in the first detent position with the outer cage. In a change in the second detent position, however, the locking slide is then moved so that the outer cage is released from the inner cage, but for the second locking slide is brought into connection with the lower standpipe part.

Finally, a third locking slide can be fastened to the outer cage and remain completely disengaged from further elements in the first locking position. Only when the rotary shaft is rotated in the second detent position, engages the third locking slide in counter-locking elements of the upper standpipe part and connects this with the outer cage.

In concrete terms, the outer cage is the upper cage part, and the inner cage is the lower cage part. Conversely, in the specific embodiment, the stand inner tube is the upper and the Standrohraußenteil the lower part of the standpipe. This is also described in the following, explicitly encompassed by the invention but are analogous to all other combinations in which inner or outer parts are reversed from top to bottom.

With some advantage, there may be a third detent position in addition to the two detent positions already described, in which the already described first, second and third detent slides are not moved further. Such a third detent position serves to operate a fourth detent slide and to bring it into a release position, which is always in a closed position in the first and second detent positions. The fourth locking slide serves to establish a connection between a foot of the lower cage part, preferably thus of the inner cage, and a basin element. The basin element is used for screwing to the bottom of the cistern, which thereby can be attached separately. Now, if the standpipe cage unit is placed on the already bolted to the bottom of the cistern Bassinelement and rotated the rotary shaft in the third detent position, the basin element connected to the foot of the lower cage part and by a change from the third detent position in the first Locking position to be fixed. Preferably, the construction is alternatively configured such that when the lower cage part is pressed onto the basin, the connection snaps in and the third latching position only has to be adjusted to open it. This also allows one Attachment regardless of the specific rotational position, since the locking means of the basin element are configured rotationally symmetrical.

Concretely, this connection, as well as the connection of the first locking element, a clamping connection, in which the locking slides biased locking clips are assigned. These locking clips enclose a respective outer element and engage in a continuous latching groove, ie a latching opening. In the region of the ends of the locking clips sliding elements may be provided, which can slide over a provided on the outer element on both sides of the locking groove scenes. In the first detent position the locking clips additionally engage in the underlying, congruent locking grooves of the inner elements, while they are moved in the first and third detent positions along the scenes in a position in which the locking clips are spread so far that they disengage the Arrive locking grooves of the inner elements and thus the connection of the respective inner to the respective outer element is resolved.

Alternatively, locking slide can be provided which have hook elements which engage in corresponding counter-locking means in the form of abutments. This also makes it possible to establish a connection which can be re-dissolved in the opposite direction.

Both types of locking slides can preferably be realized together in the invention. This will be explained in more detail below with reference to an embodiment.

1 shows a flushing device, which includes a standpipe cage unit according to the invention. The standpipe 3 . 4 is in the cage 1 . 2 and may trigger a purge using a trigger in the cage 1 . 2 be raised. At the foot 15 an inner cage 1 is a basin element 16 arranged, which can be sealingly connected to a cistern. When lifting the standpipe 3 . 4 can the water contained in the cistern in the basin element 16 inflow and through a central opening, otherwise through the standpipe 3 . 4 is closed, ausrauschen in a down subsequent toilet bowl.

Since a variety of cisterns are available on the market, the standpipe cage unit is adjustable in height, by both the standpipe of an inner standpipe 3 and an outdoor standpipe 4 is made, as well as the cage of an inner cage 1 and an outdoor cage 2 , In the 1 shown is a position in which the said elements 1 . 2 . 3 . 4 have been brought into the greatest possible extent, so show a minimal overlap.

Furthermore, the shows 1 in that the upper inner standpipe has numerous overlapping, circumferential latching grooves, the inner cage 1 two locking grooves in front and behind and the outer cage 2 two rows of recesses at the front and back.

A single locking groove of the outer standpipe 3 is only in the 2 to recognize. Through a partial section, which here a part of the inner cage 1 and the outer cage 2 removed, the location of the standpipe parts 3 . 4 concerning the cage parts 1 . 2 be recognized. However, the shows 2 the standpipe parts 3 . 4 as well as the cage parts 1 . 2 now completely pushed together. Between the standpipe parts 3 . 4 and the cage parts 1 . 2 is a scaffold 5 inserted the elements 1 . 2 . 3 . 4 different connect with each other. For this purpose, the clamping frame 5 different locking slides 11 . 12 . 13 . 14 on, which occupy different functions. Among others, have single locking slide 12 and 13 hook elements 10 on which in abutment 19 the standpipe parts 3 . 4 intervention. To better explain which locking slide which functions to take is in 3 the clamping frame 5 optional. It essentially comprises a telescopic rotary shaft 6 , which has a total of four locking slides 11 . 12 . 13 . 14 assigned. By a rotation of the rotary shaft 6 What about a handle at the top of the rotary shaft 6 can be done, the rotation shaft 6 between a first detent position, which represents the normal operating state, a second detent position, which the state of height adjustment by means of the locking slide 11 . 12 and 13 represents and a third detent position in which the standpipe cage unit using the locking slide 14 from the basin element 16 is solved, twisted.

Shown is in 3 the first stop position. A first locking slide 11 initially serves to the inner standpipe 3 with the outer standpipe 4 connect to. For this purpose, the outer standpipe 4 a locking groove, in which the clasp arms of the locking clasp 9 of the first locking slide 11 always intervene. In the first detent position shown here, the clasp arms of the latch clasp 9 of the first locking slide 11 even in a congruent with the locking groove of the outer standpipe 4 lying latching groove of the inner standpipe 3 and thereby prevent the inner standpipe 3 opposite the outer standpipe 4 shifts.

When changing to the second detent position would the rotation shaft 6 turned and the actuator lever 7 of the first locking slide 11 would be in the backdrop 8th of the first locking slide 11 be turned so far that the first locking slide 11 from the actuator levers 7 away from the outer standpipe, in the picture is moved to the right front. This would be terminal on the clasp arms of the locking clasp 9 mounted sliding over a along the locking groove of the outer stand extending gate and slide from the outer standpipe 4 Remove, causing the clasp arms from the locking groove of the inner standpipe 3 move out and release the latter.

At the same time in this change, the second locking slide 12 and the third locking slide 13 moved in the same way in the opposite direction, so that each of these locking slides 12 . 13 associated hook elements 10 in abutment 19 Hook. This will be the hook elements 10 of the second latching element 12 in abutments 19 of the outer standpipe 4 , the hook elements 10 of the third latching element 13 in abutment of the inner standpipe 3 snag. At the same time solve barbs of the second locking element 12 a connection between the inner cage 1 and the outer cage 2 so now the upper parts 2 . 3 and lower parts 1 . 4 each coupled and a suitable height adjustment can be made. This will be the telescopic rotary shaft 6 also pull apart with only the third locking slide 13 with the top of the rotary shaft 6 is moved upward.

The lower end of the scaffold 5 concerns the attachment of the basin element 16 at the foot 15 of the inner cage 1 , In the first detent position shown, the terminal sliding elements on the clasp arms of the locking clasp 9 at the fourth locking slide 14 in a left-disengaged state, in the basin element 16 and foot 15 engage each other. By a rotation of the rotary shaft 6 in the reverse direction than before in the second detent position, the rotation shaft 6 spent in the third detent position, in which the fourth locking slide is retracted and the basin element 16 from the foot 15 solves. A snapping of the foot 15 into the basin element 16 can be done in any rest position.

This detached position is in 4 represented, again with the foot displayed 15 and the basin element 16 , The foot 15 has a locking groove 18 into which the catch clip 9 intervenes. The terminal slider glides on a backdrop 17 and is located at the over the lateral surface of the foot 15 highest point. Therefore, the catch clip engages 9 Although in the locking groove 18 of the foot 15 but not in the underlying congruent locking groove of the basin element 16 ,

This is only the case again, if, as in the 5 shown the rotation shaft 6 was turned back into the first or second detent position and thereby the fourth locking slide 14 with the locking clip 9 is further disengaged. As a result, the terminal slider shifts over the backdrop 17 away to a deeper point of the scenery 7 , so the catch clip 9 not only in the locking groove 8th of the foot 15 , but also in an underlying, corresponding and congruent circumferential groove of the basin element 16 intervenes. This is a connection with the basin element 15 manufactured.

Thus, described above is a standpipe cage unit in which, by using a tensioning frame, the various elements of the standpipe and the cage can be connected to each other in a further state in addition to the operating state in which the standpipe parts and the cage parts are separated from each other and instead upper elements and lower elements are interconnected. In such a state, the standpipe cage unit can be brought into the desired extent by pulling apart or pushed together and returned there to the operating state.
