ES2247883A1 - Method for positioning of bathtub or bathtub cover on original bathtub, involves making cut in original bathtub that eliminates strip and sidewall from orifice, and locating spillway in zone of new bathtub - Google Patents

Abstract

The method involves finishing assembly and positioning of a water-drainage valve in a new bathtub. A water-drainage orifice (4) is equipped with a coning part. A cut is made in an original bathtub (2) that eliminates a strip (5) and a sidewall from the orifice. A spillway (9) is located in a zone of the new bathtub.

Description

Process for placing bathtubs or covers bathtub on original bathtubs and product obtained.

Object of the invention

The present invention, as expressed by the set forth in this specification, refers to a process for  placement of bathtubs or bathtub covers over original bathtubs and product obtained, with which it is possible to improve the installation of the new drain of the new bathtub or cover with a degree of Quality and safety similar to that of the original bathtub.

Background of the invention

All case placement processes for bathtubs or equivalent are based on bathtubs that are placed on the old and present an important problem when locating the drain valve corresponding to the hole in the bathtub original, which is the point where the pipe is located corresponding evacuation.

It usually happens that the hole of the new  bathtub or cover to be installed is misplaced or offset from the evacuation pipe This obstacle is resolved using Theoretical and complex connection pieces not existing in the market and difficult to materialize, because normally there is no space to use standard elbows or connections, which entails that the tightness of the union can be compromised.

Another way to solve this problem, as  set forth in Utility Model No. 9703372, is to provide the new bathtub, in the construction phase of the same, of a large recessed, as an elongated pool, where it can be done at afterwards the drain hole according to the needs of installation.

In any of the methods described is impossible to achieve a drain zone that properly evacuates the water and where the valve can be installed safely and effectively Drain, as happens when riding in any bathtub original. Failure to do so generates deposits and sediments around to the sump as there is no correct fall for the water.

In the old-fashioned bathtubs, you I could mold the double recess of drain, but it's very difficult that the centers of the holes are coincident, which accentuates even more when the drain pipe is vertical, which it makes it harder to connect the new drain valve, causing that the bands or wings of the new bathtub or cover that overlaps Don't fit the surrounding walls.

Among the different invention patents that can be found, based on the placement on the old another custom bathtub trying to get the sinks, with help or not of related complementary pieces, whether concentric, We can cite, among others, the following:

US 5560092, US 3614793, US 2468347, US 4067071 and US 4643853; ES 1030528, ES 2026039 and ES 1030042; and WO 9705996. In none of them contemplate the characteristics object of the present invention that solve the commented problems.

Also all covers for bathtubs or bathtubs that are installed on the old, have problems of stiffness at its base or bottom; good because they are not reinforced  or because they are reinforced with a material, such as the fiberglass or polyester, which by itself does not provide the Enough rigidity to that area.

The non-use of an adequate reinforcement is the cause of deformity in the fund or base, since usually use polyurethane foam to fill the existing hole between the two bathtubs, which when it expands grows in volume affecting all those areas that offer less resistance as is the case with a bathtub cover.

Among the different invention patents for bathtub covers none contemplates that the reinforcement of the base of the bathtub is made with two materials: one that compacts the piece, such as fiberglass; and other material that gives rigidity, such as wood, metal, or other plates materials.

Description of the invention

In general, the process for placement of bathtubs or bathtub covers over original bathtubs and the product obtained, object of the present invention, make possible achieve a perfect finish for the valve assembly drain, when providing that the new bathtub, or bathtub cover, has its drain located outside the area where the bathtub is located original, including a double recess that gives rise to the conicity conformation that allows the correct assembly of the drain valve or sump.

The original bathtub is practiced preferably a cut that widely eliminates a strip of the bottom and / or side wall, which comprises from the hole of drain until the point corresponding to the new one is exceeded location for the drain and overflow valve.

This cut will always be wide enough as to allow easy placement of standard connections existing in the market. Said court may cover one more area wide of the bath although always depending on the conditions special of each case.

Therefore, the cover or new bathtub will have the drain hole in a different area and away from that of location of the original bath drain, not less than one default measure that supports connection placement standard and its hole will have a mouthpiece equipped with the conicity or double conicity that allows to perfectly settle the drain valve or sump, so that it is achieved so that the new drain evacuate water and sediments with the same efficiency of the drains of the original bathtubs.

As for the overflow, the same location you had in the original bathtub or move it to a new.

The reinforcement of the bottom of the cover or new bathtub will be formed by the combination of two materials that provide sufficient rigidity for the materials used for the filling between the two bathtubs do not affect, by excess or default, to its settlement or its integrity.

To facilitate the understanding of characteristics of the invention and forming an integral part of this Descriptive report, a sheet of plans is attached in whose figures, with an illustrative and non-limiting nature represented the following:

Brief description of the drawings

Figure 1.- It is a plan view of a bathtub original in which it shows with dashed lines, the areas to remove from it for the installation of the sump valve in the new bathtub or cover, located in a very location different and distant.

Figure 2.- It is a plan view of the new bathtub or cover to be mounted on the original bathtub of the figure one.

Figure 3.- It is a section along the cutting line A-B in figure 2.

Figure 4.- It is a longitudinal section of the new bathtub or cover, where the arrangement of the reinforcement is appreciated From the bottom.

Figure 5.- It is a cross section of a new bathtub or cover that incorporates the reinforcement of the bottom.

Description of the preferred embodiment

Referring to the numbering adopted in the figures, we can see how the process for placing bathtubs or bathtub covers over original bathtubs, which the invention proposes, is to provide that the new bathtub or cover (1) to be mounted on the old bathtub, or original bathtub (2), have its drain hole (3) at a point away from the drain hole (4) of the original bathtub (2), thus being able to have the opening of the hole (3) the taper or double taper which requires the mounting of the sump valve to have place a correct drop for water as it happens in the assembly initial of the bathtubs.

To do this, the original bathtub (2) will carry made a cut (5) or (5 ') marked with dashed lines in the Figure 1, to eliminate this existing material between the zones of location of the original sump (4) and the new sump (3), for so that this material at the bottom of the bath does not obstruct the assembly and laying of the new drain installation.

In figure 3 we see how the back wall (6) of the new bathtub (1) or bathtub cover, it will have the conical recess or  double conical (7) for the installation of the new valve drain, referenced in general with the number (8), with the same installation guarantees as if it were the assembly in An original bathtub.

The overflow hole is referenced with the number (9) and it can be checked how in this case it remains in the same location point, although it could be placed randomly in another place, according to the cut zone made.

As we said before, to avoid deformations when expanding polyurethane foam, or fiber glass that has to interpose between both bathtubs, is placed previously a mixed fiberglass reinforcement and plates wood or metal, or similar, attached to the underside of the new bathtub or cover, such as the one referenced with (10) in figures 4 and 5.

Claims (3)
