MODULAR FLOOR AND MODULAR FLOOR SYSTEM

Description

TECHNICAL DOMAIN

[0001] The present invention is related to modular floorings and modular flooring systems comprising the interconnection of a plurality of modular floorings, whereby said systems are used in flooring, for example, of sports pavilions.PRIOR ART

[0002] Modular floorings are widely used for installing interconnected modular floorings, which are frequently used for the assembly of sports pavilions.

[0003] The modular floorings of the state of the art comprise a modular flooring component, which comprises side fastening spigots which allow the interconnection between adjacent modular floorings by means of tongue and groove connectors, which are arranged on the edges of the side walls of the modular floorings. Installing floors in sports pavilions requires incorporating elements in the modular flooring system which absorb impacts resulting from sporting activities, contribute to the lessening of noise and further allow the adequate draining of water through the modular flooring.

[0004] International patent application WO 2017 / 067546 Al, published April 27, 2017 shows a modular flooring according to the preamble of claim 1.

[0005] Portuguese patent application PT 110620 A of Rui Pedro Simões Vicente, published on September 12, 2019, discloses a modular flooring which comprises a modular floor section, interior or exterior, which is fitted and connected to a detachable base, whereby said detachable base is encased into and fixed on the bottom part of the section of the modular floor tile. The detachable base comprises a plurality of holes along the length of the surface thereof, which cross it transversely and contribute to the drainage of water through the modular flooring, which is particularly useful for the removal of water resulting from the weather in case the modular floors are exposed to the outdoors, or even for the removal of water resulting from cleaning of the modular floor tile system.

[0006] The detachable base, disclosed in Portuguese patent application PT 110620 A, further comprises a plurality of protrusions and concavities arranged on the lower surface thereof, which contribute to the absorption of impacts and to the acoustic insulation or attenuation of noise during the use of the modular flooring. In the modular flooring described in Portuguese patent application PT 110620 A, the connection between the modular flooring and the detachable base is carried out by means of the encasing into and fastening of upright spigots, arranged on the upper face of the detachable base, with cavities, arranged on the lower face of the section of the modular flooring.LIMITATIONS OF THE PRIOR ART

[0007] The modular flooring, described in Portuguese patent application PT 110620 A, presents limitations as regards the adequate connection between the section of the modular flooring and the detachable base, since the connection between the upright fastening spigots and the cavities is made by a simple fitting.

[0008] The selection of the materials for the manufacture of the detachable base, namely, a flexible material, and of the section of the modular flooring, namely a rigid polymeric material, was carried out based on the premise of meeting the purpose of having an easy encasing into and fastening between the vertical fastening spigots, arranged on the upper face of the detachable base, and the cavities, arranged on the lower face of the section of the modular flooring.

[0009] On the other hand, the easy and practical fitting among the vertical fastening spigots and the cavities presents as a disadvantage the fact that detaching the parts is also usually possible in normal conditions, which frequently causes a detachment between the detachable base and the section of the modular flooring in the course of the installation activities of the modular floorings.

[0010] In this way, during the installation of the modular flooring systems, disclosed in patent application PT 110620 A, wherein the installation comprises the interconnection of a plurality of modular floorings, there is the disadvantage of the frequent occurrence of detachment between the detachable base and the section of the modular flooring, which extends the installation works of the modular floorings and causes them to be costly in terms of the need for manpower.

[0011] In order to have some idea of the necessary workload for installing a venue with modular floorings for a sporting event, there is presented in table 1 the number of modules that are necessary for installing the sports venues for the practice of several sports. Table 1SportArea of the venue including safety areas (m 2< )Number of modular flooringsFutsal96815.488Volleyball64610.336Basketball6089.728Handball96815.488

[0012] In this way, it is concluded that the number of modules that are necessary for installing the sports venues is relatively high, which causes the workload to be significant, particularly in the context of what is expected in terms of reworking when installing the modules, when there occurs the detachment between the detachable base and the section of the modular flooring.

[0013] In this way, the state of the art requires modular floorings which comprise firmer, and more stable connection means between the detachable base and the section of the modular flooring, which allow a more rapid and efficient installation of the modular floorings. Consequently, the state of the art demands modular floorings which contribute with the reduction of the workforce throughout the installation thereof, both in the assembly of a venue as in the re-assembly thereof after performing the maintenance activity.SOLUTION OF THE STATE OF THE ART LIMITATIONS

[0014] The present invention presents connection means which exceed the limitations of the connection between a vertical fastening protuberance, arranged on the upper face of the flexible base component, and a cavity, arranged on the lower face of the component of the modular flooring, as disclosed in patent application PT 110620 A.

[0015] The present invention solves the limitations of the state of the art by the features as defined in claim 1, thus also by incorporating a vertical pin on the lower face of a component of the modular flooring and a vertical hole on the upper face of a flexible base component, wherein the vertical pin is configured to connect in a detachable way to the vertical hole. Preferably, the present invention solves the limitations of the state of the art by incorporating a vertical pin at the base of each cavity and a vertical hole on the upper wall of each vertical fastening protuberance, wherein the vertical pin is configured to connect in a detachable manner to the vertical hole in a second connection mechanism among said components. In a complementary manner, the present invention provides a third connection mechanism between a vertical fastening protuberance and a cavity based on the connection between a first male and female connection element, arranged on a side wall of a vertical connection protuberance and a second male and female connection element, arranged on a side wall of a cavity, whereby both of said male and female connection elements are aligned in the same vertical plane.ADVANTAGEOUS EFFECTS OF THE INVENTION

[0016] The modular floorings according to the invention present a firmer connection between a modular floor tile component and a flexible base component, without the connection ceasing to display the detachable characteristics thereof.

[0017] In this way, the time required for installing a modular flooring system according to the present invention is significantly reduced, making the interconnection activity between adjacent modular floorings more efficient and practical, since it is possible to mitigate the undesired detaching between the modular flooring floor component and the flexible base component.BRIEF DESCRIPTION OF THE FIGURES
