Description

VALVE WITH MANUAL INSTALLATION SET, INSTALLATION SET AND METHOD FOR INSTALLING SUCH VALVE

The present invention relates to a faucet with a set for manual installation to countertops, basins, sinks, ceramic elements or other installation surfaces.

The present invention also relates to both the installation assembly used, and the method of installing the valve element by means of the installation assembly without the use of tools.

Background of the invention

Conventionally, faucets which are fixed to surfaces such as counters, sinks, ceramic or other elements, must, on the one hand, be fixed to said surfaces by means of a pressure system connected to the valve through the space provided for the passage of the hydraulic lines and, on the other hand, they must connect the normally flexible inlet conduits to the hydraulic supply lines.

Known pressure systems for fixing the faucet use a threaded rod as a connecting element, which is fixed to the bottom of the faucet base. This rod is passed through the through hole which is present in the installation surface, and since the base of the faucet is larger and cannot pass through said hole, one threads through the bottom of the installation surface a horseshoe-shaped stopper that also cannot pass through said hole, leaving free space for the passage of hydraulic lines. The pressure which is generated between the base of the faucet and the stopper, both against the installation surface, effects the fixation of the faucet on said installation surface. This system requires a clamping action of the stopper that is long lasting and requires the use of a tool in a space that is difficult to access.

As an alternative to the above type of faucet fixing, connection elements are also known in the prior art which are fixed to the faucet formed by a threaded extension of a diameter close to the passage diameter in the through hole of the counter, of the sink or similar, using as a locking element a hexagonal nut with a diameter corresponding to the threaded extension and which is tightened with a fixed or adjustable spanner. Like the previous option, the use of tools in these small mounting spaces involves great difficulty in execution.

On the other hand, for the connection installation of the hydraulic supply lines, these must be connected to the flexible conduits which are fixed to the inlets of the valve itself. The threaded element of the pipe which must be tightened to be connected to the hydraulic supply line is connected by one of its ends to a conduit. These threaded elements, conventionally standard hexagonal nuts, have a conduit integrally connected to one end of the threaded element, and which must be tightened against the device or the conduit to which they are to be connected, preventing the use of keys which are inserted into the threaded element by the axis of rotation of the connecting thread and they have the disadvantage of being in areas with connection positions that are uncomfortable and difficult to access for the installer.

There are wing nuts in the state of the art, also called wing nuts, which allow their manual tightening, without the use of tools. The wings that protrude from the outside of the threaded element to be tightened allow the installer to exert a greater tightening torque with their hands, which frequently makes it possible to achieve the fastening force required for an ideal assembly, without the need for more tools.

This system has the disadvantage of having to be installed beforehand on a standardized type of product, such as the flexible pipes mentioned above, which leads to the existence of different types of products depending on the type of threaded element, with the problem generated in production and storage by the variability of standard products, as well as an increased cost of these water pipes.

In this way, it is necessary to have a faucet with an installation set that is easy and economical to install, allowing substantial movement of the clamping elements of its connections and fixings to be able to carry out a faster assembly and without having to use of tools, allowing optimal tightening of manually threaded elements.

Description of the invention

The object of the present invention is to provide a faucet with a manual installation assembly, as well as an installation assembly used in faucets and a method of installing the faucet on installation surfaces with the assembly. of installation above, which manage to solve the aforementioned drawbacks, having other advantages that will be described below.

According to this object, and with regard to a first aspect, the present invention is based on a faucet which is installed on a counter, a sink, a ceramic element or other installation surfaces. This valve is of the type comprising at least two fixing elements:

- a first element formed by a threaded connection element integrally joined to the base of the faucet to be fixed, of a diameter substantially identical to the open passage in the counter, the sink, the ceramic element or other surfaces of installation, in which the plumbing pipes connecting to the hydraulic lines pass through this threaded connection element; and

- a second element formed by the pipes themselves for connection to the hydraulic water supply lines.

The invention is based on the fact that the tap comprises a manual installation assembly comprising:

- a fixing element removably attached to the threaded connection element of the valve itself as the first mounting element; and

- at least one clamping element which is inserted into the threaded clamping element of the pipe as a second mounting element.

These installation kit items are configured for hand tightening, where:

- the valve fixing element comprises a body having at least:

- a thread complementary to that of the threaded connection element fully joined to the base of the valve to be fixed,

- a longitudinal through opening for the passage from one end to the other of the body, in which said longitudinal opening is configured to allow the passage of one or more hydraulic lines and/or supplies to the valve to be fixed;

- a clamping contact base against the counter, sink, ceramic element or other installation surfaces; and

- a side surface intended to be entered manually by the installing user;

- the clamping element is independent of the threaded clamping element of the pipe, engaging, at least in part, in the external geometry of the threaded clamping element, wherein the clamping element comprises:

- a coupling ring with an open interior geometry that is coupled to substantially match the exterior geometry of the threaded clamp member, configured to allow full passage of the clamp member through the entire member threaded clamp;

- one or more manual gripping and/or lever elements on the outer surface of the coupling ring.

This advantageous configuration of the faucet with its manual fixing assembly allows for simple and quick installation, without the difficulty of using auxiliary tools that are difficult to couple in hard-to-reach spaces, such as under counters, furniture, sinks, etc.

On the one hand, the advantageous incorporation in the faucet of the described faucet fixing element, allows, by means of a single element, the passage of the hydraulic lines through the counter, the sink, the ceramic element or other installation surfaces by means of the fixing element itself, as well as the clamping and fixing of the tap by means of the threaded coupling of the fixing element to the integrally joined threaded connection element at the base of the threaded tap complementary to the fixing element.

This last tightening and fixing of the valve is carried out manually, without requiring the use of tightening tools for said fixing, since the lateral tightening surface allows a correct grip to manually apply an optimal tightening torque.

On the other hand, the configuration of the independent and manual clamping element, which is coupled to the threaded clamping element of a pipe, is formed by a kind of insert which fits into the external shape of the threaded clamping element and has gripping elements, such as grooved surfaces or protruding gripping elements, which allow manual application of a sufficient tightening torque for the union to be made.

According to a preferred embodiment, the base of the fastening element comprises a grooved, splined, toothed, granulated or finished contact and pressure surface to improve its adhesion to its contact surface.

This shape of the base allows greater fixing power of the fixing element to the installation surface in its clamped position, as well as greater resistance to involuntary rotation of the fixed assembly.

In a preferred embodiment, the side surface also has projections, indentations, geometric shapes, grooves, non-slip finishes and/or the like.

This shape of the side surface allows a better tightening and fixing of the valve, obtained manually without the need to use tightening tools in said fixing, since thanks to this shape of the side surface, gripping surfaces are available such as grooves, ribs or any other finish that provides a proper non-slip grip, in order to apply optimum tightening torque by hand.

Preferably, the longitudinal through opening is the same as that comprising the thread complementary to that of the threaded connection element secured to the base of the tap to be fixed, at least at the end of the contact base tight against the counter , the sink, the ceramic element or the installation surface.

This allows the design of the fixing element to be optimized, taking advantage of the need to run the tap supply lines, with the larger diameter fixing system which normally occupies the passage width of the opening in the installation area.

In a possible embodiment of the invention, the contact base for clamping against the counter, the sink, the ceramic element or other installation surfaces preferably has an inclined toothing, with an inclination towards the direction of rotation of the clamp and a resistance in its opposite direction.

This configuration allows simple tightening, while its loosening is hindered by the sawtooth shape, which even allows the final tightening of the valve and clamping element assembly to be carried out from the valve itself, by rotating the faucet hose like a ratchet. In this way, by manually exerting a force on the tap pipe, a greater clamping force is obtained, by leverage, and the clamping is obtained by performing movements of a few degrees of rotation of the tap pipe, since in the direction of the valve loosening, it is not possible to perform the rotation of the clamping element, while, when rotating the pipe in the tightening direction, the lower screwing of the clamping element product, because it is engaged and does not follow the movement of the direction of rotation of the pipe, which, transmitted to the clamping element, would loosen it, being therefore limited by the teeth of the contact base of the clamping element.

In another possible embodiment, also preferably, the side surface of the body has a geometry compatible with a hexagonal key mounted transversely or longitudinally.

This is achieved by means of a hexagonal outer shape and/or with diametrically opposed slots which allow a fixed key to be mounted, for example, longitudinally with respect to the axis of rotation of the clamping element. In this way it is possible, if necessary, to use an auxiliary key to increase the tightening or loosening.

In a preferred embodiment of the invention, the fastening element is made from a single piece of plastic material. This realization allows the fastener to be manufactured with a low production cost, unifying the above characteristics in a single piece, also eliminating potential breaks between any independent elements that form the part of the fastener .

In this case, the plastic materials used must be resistant to the action of manual tightening for which they are intended and to the forces that will be exerted on them to achieve their purpose. For example, but preferably by way of illustration, a majority composition of polypropylene fiberglass, ABS fiberglass or polyamide fiberglass is used.

In an alternative embodiment of this last configuration, the contact base for clamping against the counter, the sink, the ceramic element or other installation surfaces, is a separate piece fixed to the body of the element. fixing, with the corresponding fluted, grooved, toothed, granulated or finished contact and pressure surface with, preferably, a high quality non-slip material on its contact surface with said installation surface, to facilitate its grip on its contact surface with said installation surface.

This configuration makes it possible to have a contact and pressure surface against the installation surface of the fastener, thus adding surface finishes, layers of specific products that allow better adhesion between said contact surface and pressure of the fastener and the installation surface of this fastener on the counter, sink, ceramic element or other surfaces.

Preferably, the clamping element used in the tap to clamp the threaded clamping element of the corresponding pipe, comprises at least one elastic stop projection protruding from the surface of said open internal geometry of the coupling ring, located in an intermediate zone of the passage which creates the open interior geometry of the coupling ring.

This configuration allows the clamp, which has a hole that substantially coincides with that of the threaded clamp, to pass through the clamp, although meeting resistance from a number of resilient protrusions. which, once overcome by the threaded clamping element, are retained in the direction opposite to that of its insertion, provided that an external disassembly force is not exerted.

The use of this clamping element in these installations with flexible pipes and the like, which have one end of the threaded clamping element connected to a conduit and which, in order to be able to use a clamping element such as that described here, must be pre-assembled, allows the manual clamping element to remain pre-assembled, without fear of its undesirable uncoupling. In this way, many sets of flexible plumbing pipes can be supplied with the clamping element pre-assembled on said flexible plumbing pipe, keeping it in its pre-assembled location, without any risk of it being inadvertently disassembled and ready for installation, coupled to the threaded clamping element, and its subsequent manual tightening being carried out without the use of tools.

In a possible preferred embodiment of the invention, the gripping and/or lever element is formed by one or more lugs, projections or geometries projecting from the outer surface of the coupling ring.

These configurations allow the manual exertion of a considerable torque, without the need for additional tools, since the lugs, projections or the different types of protrusions and/or geometries allow it, which considerably improves assembly times in places complicated, such as in installations with limited space and/or difficult access, such as water supply connections to faucets or toilet cisterns, bidets or the like.

As a variant of the above, the gripping and/or lever element is formed by a rough, grooved, non-slip or equivalent outer surface.

As in the previous embodiments, these configurations allow to perform manually, without the need for more tools, a better rotation of the threaded clamping element, since the asperities, grooves, non-slip surfaces or the like improve the manual grip on the threaded clamping element.

Preferably for the invention, the at least one elastic stop projection is installed on the inner side of the coupling ring, the walls of this coupling ring having sufficient expansion flexibility to allow the element to threaded clamp to pass through said projections by exerting pressure for its passage through the open interior geometry of the clamping element.

This embodiment allows these internal projections to maintain the possible passage of the threaded element at the level of the projections, and to retain its exit from the threaded element in the opposite direction to that of its entry.

With regard to any one of the embodiments described above, the fixing element and the clamping element are preferably made of a majority composition of plastic material.

In this respect and more preferably, the plastic material of these clamping elements corresponds to ABS plastic, to polypropylene with glass fiber or to polyamide with glass fiber. Other compositions may be used provided that they offer sufficient structural stability to be able to exert the rotational force, maintaining their internal shape in order to adapt to the threaded element and to transmit their rotation, as well as in bringing flexibility to their walls and their interior projections.

In accordance with the above objects of the invention, and with respect to a second aspect, the present invention also relates to a manual faucet installation assembly, which is used to fix faucets on countertops, sinks, ceramic elements or other installation surfaces.

This faucet installation assembly comprises at least one element for fixing to the threaded connection element and one clamping element for the threaded clamping element of the pipe, which have the characteristics described in the first aspect of the invention described above, thus configured for manual tightening.

Still according to the aforementioned objects of the invention, and with regard to a third aspect, the present invention also relates to a method of installing a faucet on a counter, a sink, a ceramic element or other surfaces of installation, without the need for the use of tools for optimal tightening of the fastening and clamping elements.

The installation method advantageously uses a tap with an installation assembly as described in the first and second aspects of the invention described above, in which the installation method comprises at least the following steps:

a) insert the tap with its pipes connecting to the hydraulic supply lines and its threaded connection element, through the hole made in the counter, sink, ceramic element or other installation surfaces;

b) pass the pipes connecting to the hydraulic supply lines inside the longitudinal through opening of the fixing element, screwing manually until this fixing element is tightened on the threaded tap connection;

c) inserting the clamping element into the threaded clamping element of the pipe, passing the coupling ring through the outer geometry of the threaded clamping element;

d) adapting the threaded clamping element of each pipe to the threaded element of each hydraulic supply line, coupling the clamping element to the external geometry of the threaded clamping element, and manually threading and tightening this element threaded clamp on the threaded element of its corresponding hydraulic supply line;

In this method, steps a) and b) are consecutive in the order indicated and form a first group of actions, while steps c) and d) are consecutive in the order indicated, forming a second group of stock. These first and second groups of actions are interchangeable in their order of execution.

With this method, based on the advantages of the valve and its installation set, it is possible to perform manual tightening, dispensing with auxiliary tools and facilitating the installation process and, therefore, reducing its costs.

Preferably, in this method, in the first group of actions, to perform the final tightening on fastener assemblies that have a fastener with teeth on the clamping contact base, there is a step after step b) in which the tightening of the faucet attachment to the counter, sink, ceramic element or other installation surfaces, is carried out by rotating the body of the pipe or faucet like a ratchet.

This advantageously provides a new and optimal way of performing the final tightening of a valve.

Description of a preferred embodiment

In the present preferred embodiment of the invention, as shown in Figures 1 and 5, the faucet 100 comprises a threaded connection element 101 integrally integral with this faucet 100 which passes through the counter 102 to which it is intended to be fixed. , to establish the fixing of the threaded connection element 101 with the fixing element 10 by its lower part.

On the other hand, the valve (100) comprises two pipes (92) supplying the valve (100) from the hydraulic supply lines, connected to the latter by a threaded clamping element (90) of these pipes , in this case hexagonal nuts, to which the clamping elements (80) are coupled by the hexagonal geometry of the outer face (91).

On the one hand, in a preferred embodiment, the fastening element 10 is made of a single plastic piece mainly composed of polypropylene with fiberglass.

This fixing element (10), as can be seen in the , is formed by a body (11) of substantially cylindrical geometry, which is traversed by a longitudinal through opening (12), forming a tube of circular section. Through this longitudinal through opening (12) pass the plumbing pipes (92) of the faucet (100), which have previously passed through the installation counter (102).

At the upper end of the body (11), or at the contact end for clamping against the counter (102), the longitudinal through opening (12) itself has a thread (15) complementary to the thread of the threaded connection element (101) of the valve (100).

The body (11) is provided on its contact base (13) for clamping against the counter (102) with a sawtooth shape, with a decreasing inclination in the direction of the clamping rotation and a tooth geometry ensuring resistance to rotation in the direction of loosening. In this way, by clamping the clamping element (10) against the surface of the counter (102), the rotation of the clamping element (10) in said clamping direction is easily achieved, while in the opposite direction, upon loosening, there is an anchoring effect provided by said contact base finish (13) against said counter (102) once contact between said elements (13, 102) has been achieved. This clamp contact base (13) forms the base of the tubular geometry of the clamp (10) at its counter contact end (102).

One effect of this tooth configuration is to allow final tightening of the assembly from the top of the installation, from the valve itself, using the pipe or valve body as a ratchet, using the retention effect discussed above.

Likewise, the lateral gripping surface (14) has a groove which increases the grip of the clamping element (10) by the hand of the user, and thus makes it possible to exert a greater rotational force and, by therefore, greater tightening, without the need to use additional tools.

The lower part of the side surface (14) has notches arranged regularly on the perimeter of this zone which form a geometry (16) compatible with a fixed key, giving said lower part of the side surface a hexagonal shape. Similarly, the presence of diametrically opposed notches allows longitudinal engagement, on the axis of rotation of the clamping element (10), of another key, such as a fixed key. These possible couplings of auxiliary keys give versatility to the clamping element (10) which, although allowing its manual tightening, also allows intervention with conventional keys to be able to carry out a final tightening or loosening, if necessary .

In other embodiments, the clamping element (10) may comprise two or more parts, so that the contact base may be a different part from that of the body and be fixed thereto during the process. of manufacture, which makes it possible to arrange layers of specific material in contact between the counter (12) and the clamping element (10).

Also as a variant, the lateral gripping surface can be covered with a piece or with an auxiliary sheet fixed to the body of the clamping element.

Finally, and as an alternative to the use of plastic materials, indicated as preferred in the construction of the clamping element (10), metallic or alternative materials can be used which provide structural stability which maintains the dimensions of the element. clamping in its clamping operation and the structure of its attachment to the installation surface, under the effects of the rotational and clamping force to which it will be subjected.

Furthermore, as shown in Figures 3 to 5, the clamping element (80) is formed by a cylindrical coupling ring (81), which has an open internal geometry (82) in the form of a hexagonal nut, in order to to be coupled to the geometry of the outer side (91) of a threaded clamp (90), in this case the hex nut of a flexible plumbing pipe (92).

The clamping element (80), in the present embodiment made entirely of ABS plastic and in a single component, although other compositions are possible, as indicated above, comprises two diametrically opposed lugs made of as gripping and/or lever elements (84), located on the outer surface (83) of the coupling ring (81).

In other embodiments, the geometry of the inner hole of the clamping element may be different, to adapt to the shape of the threaded clamping element. Similarly, as a variant, the gripping and/or lever elements can be formed by grooves, non-slip finishes, ribs and/or geometries which allow their manual gripping and the exercise of a torque sufficient for the function of fastening required.

In the preferred embodiment, the clamping element (80) has in its inner hole a number of resilient projections (85), which reduce the space of the open inner geometry (82), thus preventing the passage of the threaded element (90) through the hole formed by said open interior geometry (82). These protrusions (85) are located at the vertices which define the hexagonal open interior geometry (82), and aligned at the same depth as the passage formed by said hole.

With these protrusions (85), when inserting the clamping element (80) on the hex nut of the flexible plumbing pipe (92), to fully enter it will be necessary to press the clamping element clamp (80) at the point in its depth where the projections (85) are reached, so that once inside, removal of the clamp (80) is not accidental and is always linked to the flexible plumbing pipe (92), ready for its installation without tools.

Although it follows from the operation indicated above for this faucet (100) with manual assembly, the method of installing this faucet (100) on a counter, a sink, a ceramic element or other surfaces installation (102), includes the following steps:

a) introduce the tap (100) with its pipes (92) for connection to the hydraulic supply lines and its threaded connection element (101), through the hole made in the counter, the sink, the ceramic or other installation surfaces (102);

b1) pass the pipes (92) connecting to the hydraulic supply lines through the interior of the longitudinal through-opening (12) of the fixing element (10), screwing manually until this fixing element (10) is tightened on the threaded connection element (101) of the valve (100);

b2) clamp the faucet (100) to the counter, sink, ceramic unit or other installation surfaces (102), by rotating the hose or faucet body (100) like a wrench pawl;

c) inserting the clamping element (80) into the threaded clamping element (90) of the pipe (92), passing the coupling ring (81) through the outer geometry (91) of the threaded clamp (90), until overcoming the flexible projections (85);

d) matching the threaded clamp member (90) of each pipe (92) to the threaded member of each hydraulic supply line, coupling the clamp member (80) to the exterior geometry of the clamp member (90) and threading and manually tightening this threaded clamping element (90) on the threaded element of its corresponding hydraulic supply line;

Although reference has been made to a specific embodiment of the invention, it will be apparent to a person skilled in the art that the faucet with the manual attachment assembly, the integrated faucet installation assembly and the method of installation described here are subject to numerous variations and modifications, and that all the aforementioned details can be replaced by other technically equivalent details, without departing from the scope of protection defined by the appended claims.
