Description

FIELD OF THE INVENTION

The present invention generally relates to the use of modular indoor or outdoor floorings, more specifically to a system for connecting and method of fitting together the modules that constitute the floor covering by means of male and female elements, which are not part of the modules and that are coupled to them.

BACKGROUND OF THE INVENTION

Modular systems for floor coverings have been well known since long. There is a huge variety of documents that refer to them, whether coverings made of natural materials such as wood or cork or made of synthetic or artificial materials.

The most classical method for fixing the modules to the floor consists of placing an aggregate material immediately above the floor upon which the covering is to be placed. This method has several disadvantages, being one of them the fact that the modules are easily damaged as upon fixing, any expansion or shrinkage which is common in any material, will cause the appearance of cracks and deformations. Therefore, the need for replacement of the modules becomes more pressing, which is also made difficult by the fact that the modules are fixed to the floor.

In response to this problem, coverings in which the modules fit together by means of solutions involving a male member and a female member have begun to emerge. Several documents relating to this solution may be mentioned, for example, WO2001098604 document disclosing a “floor covering with coupling means” or FR2917761 document disclosing a “Removable floor, for example, for a dance hall, with connections and cooperating interlocking units with each adjacent modular element”, or still the EP2010733 document that mentions a “Connection system for a mobile floor”.

Additionally, document WO2006113228 “Sub-flooring assembly and method” refers to an assembly comprised of sections that include male elements and female elements at the ends of the sections and also discloses the method of assembling the sections.

The assembly disclosed in the cited document differs from the present invention in the way that the male element and the female element are both present in the same section, while in the present invention the male element and female element are in different sections. The method to assembly the sections also differs from the method disclosed in the present invention.

Other existing solutions, which are also mentioned in several documents, involve the placement of a support structure immediately above the floor, being the modules made to fit in this structure. Refer to the WO2010079462 document featuring a “Modular floor system” and US2009249732 document that mentions a “modular floor system”.

BENEFITS OF THE INVENTION

However, all methods described above have the disadvantage that, in order to implement the above stated solutions the modules will have to be manufactured with embedded locking systems, which makes the solutions costlier.

The main advantage of the solution presented in this invention is to provide a solution that can be adapted to any existing floor type, since the connection between modules is achieved by fitting two elements, a male and a female element, which are not embedded in the modules, and that are coupled to them being fixed by a fastener system.

Method of Fitting Male and Female Elements

According to FIGS. 12 and 13, in order to couple the female element (1) with the male element (2), the female element (1) and the male element (2) shall have to be positioned in substantially parallel planes, and the minor plate of the male element (2.3) substantially aligned with the track (1.2).

Then the male element (2) must be displaced so that the minor plate of the male element (2.3) gets in touch with the track (1.2), being the latch (2.3.1) substantially coplanar with groove (1.5). Simultaneously, the edge (1.3) should fit in the space between the side wall of the inferior plate (2.2) and the side wall of the major plate of the male element (2.1).

The male element (2) must be pushed until the latch (2.3.1) enters the groove (1.5), this movement should continue until the latch (2.3.1) is completely under the superior plate of the female element (1.4). This fact occurs when the vertical wall of the superior plate of the female element (1.4) immediately above the groove (1.5) comes into contact with the vertical wall of the inferior plate (2.2) closest to the latch (2.3.1). At this time, the protrusion (2.2.1) of the inferior plate (2.2) will sit and fit in the notch (1.3.2) of the edge (1.3) and the protrusion (2.2.2) of the inferior plate (2.2) will sit and fit in the notch (1.3.1) of the edge (1.3).
