Description

DESCRIPTION Procedure for the manufacture of a shower tray and shower tray obtained.

OBJECT OF THE INVENTION 5

The purpose of the present invention patent application is to register a process for the manufacture of a shower tray that incorporates notable innovations and advantages.

 10

More specifically, the invention proposes the development of a process for the manufacture of a shower tray from a previously molded part that is made of artificial stone material, such as silestone, in which the formation of an orifice is provided. evacuation around which slightly inclined and converging walls will be arranged towards the evacuation hole in a shorter manufacturing time 15 and without the need for the use of manipulation accessories of the upper surface of the artificial stone material.

The scope of the invention is that which covers the industry dedicated to the production of shower trays. twenty

BACKGROUND OF THE INVENTION

There is currently a wide range of shower tray models. One of them is that which is manufactured from artificial stone material such as the so-called quartz (silestone) in which a water evacuation hole is provided whose characteristic in the arrangement around converging walls. To perform this operation, numerical control machines are used.

However, the use of numerical control machines in practice requires a considerable time that can reach 30 minutes, which implies an extended process over time and an important energy consumption caused by the use of the machine numerical control

DESCRIPTION OF THE INVENTION 35

The present invention has been developed in order to provide a method that is configured as a novelty within the field of application and resolves the aforementioned drawbacks, also providing other additional advantages that will be apparent from the accompanying description. continuation. 40

It is therefore an object of the present invention to provide a process for the manufacture of a shower tray from a previously molded part that is made of artificial stone material, such as silestone, in which the formation of a evacuation hole around which slightly inclined walls and 45 converging towards the evacuation hole are arranged. More particularly, a temporary fixation of the piece is carried out along points arranged in its perimeter zone inside a compartment while in the evacuation hole a tooling is arranged that is coupled to said evacuation hole, said being movable tooling through a guiding element, in which at least one stage of heating is subsequently applied at a temperature between 100-140 ° C, such that the surface region around the evacuation orifice is susceptible to deformation, forming walls with an angle of inclination and converging around the evacuation hole.

Thanks to these characteristics, considerable energy savings are obtained by reducing the time required to obtain the convergent walls towards the evacuation hole and, consequently, a cost savings in the manufacture of this type of shower trays.

Preferably, the heating step is carried out in a conventional oven. 5

The heating stage is carried out at least once for a period of approximately five minutes.

Preferably, the guiding element consists of a threaded rod arranged vertically with respect to the horizontal plane of the shower tray.

According to another aspect of the invention, the fixation of the piece inside is carried out by means of pressure elements adjustable in force.

Other features and advantages of the process object of the present invention will be apparent from the description of a preferred but not exclusive embodiment, which is illustrated by way of non-limiting example in the accompanying drawings, in which:

DESCRIPTION OF A PREFERRED EMBODIMENT

 30

In view of the aforementioned figures and, according to the numbering adopted, an example of a preferred embodiment of the invention can be observed therein, which comprises the parts and elements indicated and described in detail below.

The process for manufacturing the shower tray made from a previously molded part (1) 35 is made of artificial stone material, such as silestone, in which the formation of an evacuation hole (2) is provided around the which are slightly inclined walls converging towards the evacuation hole, as shown in figure 1.

 40

Specifically, a temporary fixation of the piece (1) is carried out along points arranged in its perimeter area inside a compartment (3) of substantially hollow and prismatic rectangular shape internally hollow and open in its upper part while in the evacuation hole is provided a tooling (7) that is coupled to said evacuation hole (2), said tooling (7) being movable through a guiding element (8) 45 formed by a threaded rod, in which subsequently apply at least one heating stage at a temperature within a range of 100-140 ° C, and more preferably at a temperature of 120 ° C for a couple of intervals of approximately five minutes.

 fifty

Mention that the tooling (7) has a shape that adapts to the contour of the evacuation hole (2), being constituted by a thread attachable to the guiding element (8) and a section of plate made, for example, of a resin. The threaded rod is fixedly attached to the base of the compartment (3) and crosses the plate section.

The fixing of the part (1) inside the compartment (3) in order to press the perimeter zone of said part is carried out by means of force adjustable pressure elements shown schematically in Figure 2 , having provided a series of profiles (4), support elements (5) and sergeant tools (6) that allow the piece (1) to be kept in the air, although any other suitable fastening means that facilitates placement and installation could be used removal of the piece inside the compartment (3).

In this way, the surface region around the evacuation hole (2) can deform as seen in Figure 3, forming walls with an inclination angle (α) and converging around the evacuation hole (2).

The heating stage is carried out in a conventional oven, so that the heating means used will not be introduced in greater detail. fifteen

The details, shapes, dimensions and other accessory elements, as well as the materials used in the manufacture of the shower tray part of the invention may be conveniently replaced by others that are technically equivalent and do not depart from the essentiality of the invention or the scope defined by claims 20 which are included below.
