Description

Flushing mechanism for toilet tank with axial and vertical stop

Technical Field

The present invention relates to a flush mechanism for a toilet tank having axial and vertical stops for the purpose of stopping in height and axial stop positions and improving adjustment of the tank flush mechanism.

Background

In the prior art, one of the most important actions in the installation of a toilet tank flush mechanism is height adjustment to accommodate the size of the tank, and the range of activation to ensure its proper operation. In this sense, document WO2017/098067 describes a device for height adjustment of a flushing mechanism for a cistern, the device comprising an elongate member fitted within a hollow portion passing through an upper base of a flushing mechanism body, wherein the position of the elongate member is adjustable in its axial direction and the elongate member is associated with a part of a biasing mechanism which, when activated, causes the body of the flushing mechanism to move through the elongate member.

The hollow of the body of the drainer comprises a through pipe defined by two facing extensions starting from the upper base of the body, through which the upper base of the body also passes. The two facing extensions fit within a circular through hole formed in a clamping member coupled around the facing extensions forming a neck structure, wherein the outer sides of the facing extensions are in contact with the contour of the through hole of the clamping member with rotational mobility around the facing extensions.

The two facing extensions having opposing inner portions facing opposing portions of the elongated member; wherein in the blocking position of the elongated member the clamping member deforms the facing extensions so that the elongated member is axially retained by the inner portions opposite the two facing extensions, and in the release position the clamping member does not deform the facing extensions and the elongated member has axial mobility.

Although this document describes a practical solution for adjusting the height of the drainer, it does not solve the problem of movement of the entire mechanism during its installation, as it may undergo undesired vertical movement during said installation.

On the other hand, the prior art also comprises document EP3382114a1, which describes a perfected device for assembling a water tank drain, which can act on an elongated element ending in a disc-shaped portion, which in turn can connect an external push-button to a water tank flushing mechanism inside the actual water tank, which is essentially characterized in that it comprises a first mechanism for adjusting the height of the elongated member and a second mechanism for blocking the movement of the flushing mechanism in the vertical direction. The first adjustment mechanism comprises a horizontal sliding plate fitted with two bars, also horizontal, parallel and protruding, and having notches on its sides. In addition, the first adjustment mechanism also comprises four members acting as vertical struts, said elongated member being interposed axially between said four members, while all four members are arranged between the two horizontal rods, in contact with their respective notches. Finally, the second vertical blocking means comprise a cantilevered portion designed to be gripped.

In the last case, it is clearly observed how the so-called first and second mechanisms are difficult to perform mechanically and it is not guaranteed that the flushing mechanism is sufficiently fixed in both positions.

Disclosure of Invention

It is an object of the present invention to provide a flush mechanism for a toilet tank having axial and vertical stops to stop and secure all components of the mechanism in a particular position while allowing the height of the mechanism to be adjusted, particularly during installation of the flush mechanism in the tank or during transport and storage of the flush mechanism prior to installation. This object is achieved by the features of the mechanism set forth in claim 1. Additional features of the mechanism of claim 1 are indicated in the dependent claims.

In particular, therefore, the mechanism of the invention comprises an elongated member fitted within a hollow passing through the upper base of the actuating bridge of the drainer, wherein the position of said elongated member is adjustable in the axial direction thereof and said elongated member is associated with a portion of a push-button mechanism which, once activated, moves the actuating bridge of the drainer downwards through the elongated member, and said mechanism comprises first axial blocking means, characterized in that it also comprises blocking means for the actuating bridge, thereby preventing an undesired movement of the actuating bridge in the Z-axis.

The blocking means of the actuation bridge again comprise two practical embodiments. The first embodiment comprises a blocking element, substantially configured as a U-shaped part, which can be inserted horizontally into the overflow, thus preventing all parts of the flushing mechanism from moving. In this case, all components of the flush mechanism cannot move. Incidentally, when the height of the drain is adjusted, the actuating bridge will also be prevented from moving.

In a second practical embodiment of the blocking device of the actuating bridge, the invention describes a blocking element which is substantially configured as a U-shaped part, the ends of which are in turn bifurcated and can be inserted into a wedge in a drain. In this case only the actuation bridge will be blocked, while the overflow will not be blocked. In either case, it will be easier to block the mechanism when adjusting the height of the drain. This blocking also prevents the wedge from being removed or lost during its transport or installation, as will be explained in more detail below.

Throughout the description and claims the word "comprise" and variations of the word, such as "comprises" and "comprising", are not intended to exclude other technical features, additives, components or steps. Additional objects, advantages and features of the invention will become apparent to those skilled in the art upon examination of the following, in part, and by practice of the invention.

Detailed Description

Considering the numbering scheme used in the drawings, in its two practical embodiments, the flushing mechanism for toilet tanks with axial and vertical blocking comprises a height-adjustable elongated member 1, the elongated member 1 being fitted inside a through-tube defined by two facing extensions 3, the two facing extensions 3 constituting a structure configured: (a) allowing passage of the elongated member 1; and (b) in the blocking position, blocking the passage of the elongated member 1, thereby blocking the passage of said elongated member 1. The facing extensions 3 start from the upper base 4a of the actuating bridge 4, which is part of the drainer 5 of the tank (not shown in the figures), and the upper base 4a of the actuating bridge 4 also passes through this through-pipe.

The two facing extensions 3 are also configured to allow attachment or connection of a clamping member 8, the clamping member 8 having a through hole 9 in which the outer sides of the two facing extensions 3 fit. Said clamping element 8 is also axially retained between the upper base 4a of the actuating bridge 4 and the outer surfaces of the two facing extensions 3. However, the inner surface of the facing extension 3 is in contact with the elongated member 1. The clamping part 8 is precisely configured such that: (a) in the open position, it allows the elongated member 1 to move freely through its through hole 9; and (b) in the blocking position, by rotating said clamping members 8, the facing extensions 3 are pressed against the elongated member 1, thereby preventing the elongated member 1 from moving.

Furthermore, according to the invention, the above-mentioned axial blocking means, constituted by the facing extensions 3 and clamps 8, should be supplemented by a vertical blocking achieved by the blocking means 10, 20 of the actuation bridge 4, so as to prevent the actuation bridge 4 from undesired movements in the Z-axis, and to set all the elements of the mechanism in specific positions so that its height can be adjusted, in particular during installation or during transport and previous storage.

Fig. 1 shows a first practical embodiment of the blocking means of the actuation bridge. These blocking means comprise a blocking element 10, configured substantially as a U-shaped part, which can be inserted horizontally into the overflow 41, thus preventing the movement of all parts of the mechanism, as can be seen best in fig. 1A.

Fig. 1B shows the barrier 10 of the first practical embodiment in more detail. The barrier comprises two distinct sections or regions. The first region is a grip or handle that can be inserted or withdrawn. The first zone, which has the shape "H" (see 101), is placed horizontally on a base 102 from which two

arms

103, 104 diverge and whose ends 103a, 104a face each other and are inclined at a certain angle a with respect to the horizontal axis X, delimiting an inner space 105 which is substantially circular and whose inner diameter is greater than the outer diameter of the overflow 41, so that it can fit completely between the barrier 10 and the above-mentioned overflow 41, the overflow 41 being an integral part of the actuating bridge 4.

This configuration has a number of advantages. On the one hand, by preventing the parts constituting the actuation bridge 4 from moving, the short pipes of the overflow 41, from which the overflow 41 is guided by the guiding means, are prevented from leaving their housing, allowing the overflow 41 to function properly. This typically occurs during shipping or installation because the entire mechanism is not in its usual position and because the parts are loose, they may become dislodged. If the overflow 41 leaves its guide means, different risk factors may arise, such as leaks or blockages in the mechanism, so that the water tank cannot be closed correctly, resulting in a loss of water.

Fig. 2 shows a second practical embodiment of the blocking means of the activation bridge 4, which comprises a blocking element 20, which is configured essentially as a U-shaped part, the ends of which in turn diverge and can be inserted into a wedge 21 of the activation bridge 4, as can be better seen in fig. 2A.

On the other hand, fig. 2B shows the blocking member 20 of the second embodiment in more detail. The stop 20 comprises a grip area 201, which grip area 201 facilitates the insertion and extraction of the stop 20 with respect to a wedge 21 of the drain 5, wherein the wedge 21 is independent of the actuating bridge 4. For this purpose, the grip area 201 also has longitudinal relief elements 201a, facilitating the task for the operator. Two

arms

202, 203 extend from the grip region 201, forming a "U" shape that delineates a generally semi-circular inner surface 204. On the other hand, each

arm

202, 203 is bifurcated at its end by a

projection

203a, 203b, 202a, 202b projecting from the

arm

202, 203, thereby forming a right angle. The

projections

203a, 203b, 202a, 202b on each side of each

arm

202, 203 form a

space

205a, 205b configured to be completely insertable into the wedge 21 of the drainer 5, and in turn independent of the actuating bridge 4, with a

semicircular stop

206a, 206b also on the inside of the

outer projections

202a, 203a, and a second

inner stop

202c, 203c in relief in the region where the

inner projections

202b, 203b meet their

respective arms

202, 203. Thanks to this structure, the tab 21 will be prevented from being detached or lost during transport or installation, since the tab 21 is located in the gap immediately after the coupling between the actuating bridge 4 and the wedge 21 of the drainer.
