Description

The present invention relates to a control plate assembly of a flush tank.

In particular, the present invention relates to a control plate assembly comprising a mounting support plate that can be attached to a wall (or other support), and a control plate connected to the support plate via an opening mechanism, whereby the plate can move relative to the support plate for opening an access opening into the tank, which can be used, for example, to introduce a service additive into the tank, such as a sanitary fluid or tablet.

As you know, wall-mounted or built-in flush cisterns are usually equipped with control keys that are mounted on a wall-mounted plate. The keys control the elements that drive the flush valve and are installed passing through an inspection hole created in the wall and covered by a plate. To install the plate, a support plate is usually used in the form of a frame that is attached to the wall or to the front wall of the tank, for example, using screws. The plate is attached to the base plate with the possibility of removal, so that, if necessary, provide access to the actuators and the flush valve.

In certain known solutions, the plate can be removed or moved relative to the base plate, even to make it possible to refuel the sanitary device in the tank, for example, to replenish the sanitary liquid or tablet.

Various systems are known for attaching a plate to a support plate, which, however, are not completely satisfactory, especially in terms of ease of installation, efficiency and versatility.

Thus, the object of the present invention is to propose a control plate assembly for a flushing cistern that eliminates the disadvantages of known solutions in a simple and inexpensive manner, and in particular, which is extremely easy to manufacture, assemble and install, while at the same time it will be absolutely efficient and reliable, will allow easy access to the inside of the tank for supplying, for example, a service additive, for example, filling the sanitary device with sanitary liquid or a tablet.

This problem is solved using the present invention, which relates to the node of the control plate of the flushing tank, the essence of which is defined in paragraph 1 of the attached claims, and its preferred features in dependent paragraphs.

The plate assembly of the present invention is simple to manufacture, assemble and install, while it is also absolutely effective and reliable.

In particular, the plate assembly of the present invention can be opened in a simple and convenient manner, gaining access to the inspection hole and, thus, the interior of the wash tank.

The present invention is further described using the following non-limiting example, with reference to the accompanying drawings, of which:

figure 1 shows a General view with a spatial separation of parts for the site of the control plate of the flushing tank, according to the present invention;

Figures 2 and 3 show two corresponding front views of the part forming the mounting support plate and which is part of the control plate assembly of the present invention, with a support for the control elements shown in corresponding non-rigid positions;

figure 4 shows a General view, when viewed from the rear, of the plate assembly shown in figure 1, after assembly;

Figures 5 and 6 are general views, when viewed from the front and rear, of a portion of the side edge of the control plate assembly shown in Figure 1, shown in the open position;

in Fig.7 shows a General view of the component node of the control plate shown in Fig.1; and

Figs. 8 and 9 show in detail the control plate assembly shown in Fig. 1 in corresponding non-rigid positions.

As shown in figure 1, the node 1 of the control plate of the flush tank, which, in fact, is known and therefore not shown, contains a mounting support plate 2, which can be attached to a wall or other support around the inspection hole, which provides access to the flush tank and a control plate 3 connected to the support plate 2 by means of a fixing system 4.

The control plate assembly 1 serves as a support for the actuator 5, which can be connected to a flush valve (not shown) of the flush tank.

In the example shown, the control plate assembly 1 is configured to use a double flush valve, that is, of a type that allows, as an alternative, to discharge two different amounts of water from the tank (full discharge and partial discharge of water contained in the tank) when the help of two actuators, therefore, the plate 3 carries a pair of keys 6 connected to the corresponding actuators of the flush valve through the corresponding control elements 7.

As also shown in FIGS. 2 and 3, the support plate 2 comprises an annular frame 10, for example, substantially rectangular in shape, which defines an opening 11; the frame 10 is substantially flat and has a front surface 12 defining a plane P and a rear surface 13 substantially parallel to the plane P; around the hole 11 there is a side wall 14, essentially perpendicular to the surfaces 12, 13 and the plane P.

The frame 10 can be attached to an external support element (for example, a wall or panel) using suitable known fasteners (for example, screws), which can be inserted into special seats 15 made on the frame 10.

The frame 10 is substantially rectangular in shape and has (referring to the position of the control plate assembly 1 with regular use) a pair of sides 16, as well as a lower transverse element 17 and an upper transverse element 18.

The frame 10 is provided with a support 20 for the control elements 7, in particular, for the rod parts 21 of the control elements 7, which connect the keys 6 of the plate 3 with the flush valve.

The support 20 includes a rotatable body 22, provided with at least one seat 23, passing through this body 22 and made in such a shape as to take the control element 7.

In the shown example, the support 20 has a pair of seats 23 located side by side, created on the respective opposite lateral edges of the body 22 and passing through this body.

The body 22 has a connecting part 24, pivotally connected to the frame 10, and a supporting part 25, which protrudes from the connecting part 24 into the hole 11 and carries seats 23.

In the example shown, the body 22 has a substantially L-shaped section; the supporting part 25 is made in the form of a substantially flat plate, which during use is located essentially parallel to the plane P and essentially perpendicular to the connecting part 24, which is pivotally connected to the corresponding side edges opposite the frame 10.

In particular, the frame 10 has a pair of connecting elements 26, which protrude from the lower transverse element 17 of the frame 10 into the hole 11, namely, from the part of the side wall 14 forming the lower transverse element 17; the body 22 is pivotally connected to the frame 10, for example, by means of a pair of pins located opposite each other, which are installed in the corresponding seats, providing rotation, and, for example, are inserted into these seats with a snap; the pins protrude from the respective lateral edges of the connecting part 24 and are installed in the corresponding seats created in the elements 26, or vice versa.

The support 20 can be rotated about a pivot axis R parallel to the transverse member 17 and the plane P, thus substantially horizontal during use.

The support 20 can be rotated, selectively adopting the operating operating position (Figure 2), in which the supporting part 25 protrudes into the hole 11 for receiving control elements 7, their direction and as their support, and the operating position of the inspection or maintenance (Figure 3 ), in which the supporting part 25 is located outside the hole 11.

In particular, the support 20 can be rotated at least 90 ° around the axis R to free the hole 11, in the preferred case, the support 20 can be rotated 180 ° about the axis R, which allows you to set the support part 25 parallel to the plane P and with the opposite side of the axis R.

The control plate assembly 1 preferably includes a system 27 for blocking the support 20 to hold the support 20 in a non-rigid operating position; for example, the locking system 27 includes at least one tooth 27A that protrudes from the support 20 and snaps into the blocking seat 27B created on the support plate 2 in a releasable manner; the tooth 27A can be selectively inserted into the seat 27B and removed from it when the support 20 is rotated.

In the shown example, the system 27 comprises a pair of opposed teeth 27A that protrude from the respective opposite side edges of the body 22, in particular from the connecting part 24, and snap into the corresponding blocking seats 27B created on the connecting elements 26.

When the node 1 of the control plate is installed, the support 20 is in a non-rigid operating position and serves as a guide and support for the control elements 7, which are inserted into the seats 23.

If there is a need for access to the inside of the flushing tank, for example, for inspection or maintenance reasons, the support 20 is rotated about the R axis to free the hole 11 and have access to the interior of the tank without obstruction from the side of the support 20; the control elements 7, disconnected from the flush valve, can also remain inserted into the seats 23 and rotate together with the support 20 out of the hole 11.

As further shown in FIGS. 4 to 6, the plate 3 is attached to the support plate 2 by means of a fixing system 4.

The fastening system 4 includes: an edge fastener 28 created on the first side edge 29 of the control plate assembly; the hinge element 30, which has opposite lateral edges 32, 33, pivotally connected to the support plate 2 (more precisely with the frame 10) and with the plate 3, respectively; and a releasable locking device 34 created on the second side edge 35, opposite the edge 29, of the control plate assembly 1, which selectively locks the plate 3 with the support plate 2 and releases the plate 3 from the support plate 2.

The fastening system 4 connects the plate 3 with the support plate 2 so that the plate 3 can move relative to the support plate 2 between the closed position (Figure 4), in which the plate 3 is connected to the support plate 2 in a single unit, is opposite and next to this plate 2 and closes the hole 11, and the open position (Fig.5 - Fig.6), in which the plate 3 is released from the support plate 2 and leaves the hole 11 at least partially open.

The mount 28 contains one or more teeth 36 located on one edge of the plate 3, which sit on the corresponding mounting seats 37, created in the support plate 2 and more precisely on the rear surface 13 of the frame 10. The teeth 36 are made so that they are attached in the transverse towards the back plate 2 to hold the back plate 3 relative to the back plate 2 in a direction substantially perpendicular to plane P.

As further shown in FIG. 7, the hinge element 30 extends along the longitudinal axis A between the two longitudinal edges 38, 39 and in the transverse direction between the side edges 32, 33.

The hinge element 30 comprises a monolithic body 40 made of plastic (polymer material) of such a shape that it is elastically deformable and, more precisely, flexible in the transverse direction relative to axis A.

In particular, the body 40 comprises a base plate 41 and two pairs of brackets 42, 43 that protrude from the base plate 41 and create side edges 32, 33 of the hinge element 30, respectively, and are pivotally connected to the support plate 2 and the plate 3, respectively.

The brackets 42 comprise respective root parts 44 that protrude from the base plate 41, and corresponding rotary parts 45 that protrude from the root parts 44 and are shaped to be flexible relative to the root parts 44, for example, by connecting to the root parts 44 when using appropriate connecting parts 46 of limited cross section. In addition, the brackets 43 have corresponding contact parts 47 that protrude from the rotary parts 45.

The hinge element 30 is located essentially parallel to the lateral sides 16 of the frame 10, and the axis A during use is essentially vertical.

The hinge element 30 is pivotally connected to the support plate 2 through the first rotary elements 51, 52, working together with each other and created on the hinge element 30, in particular, on the brackets 42, and on the support plate 2, in particular, on the side wall 14 of the frame 10, respectively; the hinge element 30 is also pivotally connected to the plate 3 through the second rotary elements 53, 54, working together with each other and created on the hinge element 30, in particular, on the brackets 42, and on the plate 3, in particular, on the supporting part 55, which protrudes from the rear surface 56 of the plate 3, respectively.

The pivoting elements 51, 52 and 53, 54 define corresponding parallel axis of rotation.

For example, the pivoting elements 51, 52 and 53, 54 consist of corresponding pairs of pins and seats occupied by pins, the pins and seats being created on the hinge element 30, and the support plate 2 and the plate 3, respectively, or vice versa.

In the example shown, the hinge element 30 is provided with a first pair of opposing pins 51 formed on the side edge 32 and protruding from the respective opposing longitudinal edges 38, 39, more precisely from the respective brackets 42, to enter the corresponding seats 52 created on the side wall 14 of the frame 10, and a second pair of opposing pins 53, created on the side edge 32 and also protruding from the respective opposing longitudinal edges 38, 39, in particular from the respective brackets 43, to enter the respective Head to Head space 54, created in the support portion 55 of the plate 3.

The hinge element 30 created by the body 40 is elastically deformable for selective adoption:

- the initial undeformed state, which the hinge element 30 accepts when it is not installed in the node 1 of the control plate, and it is not affected by any forces;

- stress strain state, which the hinge element 30 takes when it is installed in the node 1 of the control plate with pins 51, 53 inserted into the corresponding seats 52, 54.

The pins 51, 53 of each pair are aligned relative to each other on the respective axes, the corresponding seats 52, 54 are also aligned on the corresponding axes.

In the initial undeformed state, the distance between the axes of the pins 51, 53 (measured perpendicular to these axes) exceeds the distance between the axes of the seats 52, 52 (measured perpendicular to these axes) in the closed position of the plate 3, i.e., when the plate 3 completely covers the hole 11 and attached to the support plate 2.

When the hinge element 30 is installed in the control plate assembly, the pins 51, 53 are inserted into the corresponding seats 52, 54.

When the plate 3 is in the closed position, the hinge element 30 assumes a strained, strained position in which the body 40 is compressed in the transverse direction to the axis A and exerts an elastic action when released from the blocking device 34.

A releasable locking device 34 is created on the edge 33 of the control plate assembly 1 and includes a movable member 60 for securing and releasing the contact member 61 located on the plate 3.

In particular, the movable element 60 is located on one side 16 of the frame 10 and can slide in a direction parallel to the plane P and essentially perpendicular to the side 16 in the guide 62 created on the frame 10.

Element 60 includes a control portion 63, which protrudes from the frame 10 to the outside of the guide 62 and is placed in a cavity 64 created on the peripheral edge 65 of the plate 3; and a hook portion 66 that selectively engages with the contact member 61.

The contact element 61 protrudes from the supporting part 55 on the rear surface 56 of the plate 3. For example, the contact element 61 protrudes parallel to and spaced apart from the surface 56, and a sliding seat 67 is created between the surface 56 and the contact element 61, in which the hook part slides 66.

Element 60 can be moved between two non-rigid positions:

- a locked position in which the hook portion 66 is engaged with the contact element 61 and locks the plate 3 relative to the support plate 2, thus, in particular, preventing the rotation of the plate 3 relative to the support plate 2 by means of the hinge element 30;

- the released position, in which the hook-shaped part 66 is not engaged with the contact element 61, and the plate 3 can be rotated relative to the support plate 2 using the hinge element 30.

The element 60, namely its hook-shaped portion 66, and the contact element 61 are shaped to attach the plate 3 to the support plate 2 in a direction substantially perpendicular to the plane P.

In use, when the plate 3 is brought into the closed position, the element 60 (which can be spring loaded) is pushed laterally outward by the contact parts 47 of the hinge element 30, which operates in contact with the element 60.

The plate 3 is attached to the support plate at the edge 29, using the edge mount 28.

The plate 3 can be rotated relative to the support plate 2 by means of the hinge element 30, to bring from the open position to the closed position, and vice versa.

The movement of the plate 3 also leads to the rotation of the hinge element 30, which is pressed by the contact parts 47 to the element 60, thereby retracting the element 60 and allowing the contact element 61 to be inserted into the seat 67.

When bringing the plate 3 into the closed position, the element 60 is connected (through the hook-shaped part 66) with the contact element 61, thereby securing the plate to the support plate 2.

The hinge element 30 is shaped to function as a spring on the element 60.

In particular, when the hinge element 30 is in a stress-strain state, it creates a force that holds the element 60 in a locked position, in which the hook-shaped portion 66 is engaged with the contact element 61 and, thus, locks the plate 3 to the support plate 2. Element 60 can move against the elastic action exerted by the hinge element 30 on the element 60 when the hinge element 30 is in contact with the element 60.

In order to free the plate 3 from the support plate 2 and gain access to the hole 11, for example, for refueling the sanitary device installed in the tank, the element 60 is pressed against the inside of the control plate assembly 1 against the action of the hinge element 30, as a result of which the hook-shaped part 66 releases contact element 61.

At this point, the plate 3 can be moved away from the base plate by turning the plate 3 again relative to the base plate 2 by means of the hinge element 30.

And finally, it should be clear that in the described and shown here the node of the control plate can be made additional modifications and changes that do not go beyond the scope of the paragraphs of the attached claims.
