Definitions

• the present invention relates to the field of modular floor mats, in particular intended to be positioned at the entrance of buildings, embedded in a structure or installed in a pit.
• a modular floor mat intended to be installed in pits at the entrance of a building, i.e. in a recess or cavity made in the ground, is known from the prior art.
• This type of mat is composed of a plurality of aluminum profiles, arranged and attached parallel to each other. Each profile has means of connection to another profile and an upper portion receiving a coating element, such as a scraping or drying insert.
• This type of mat has a low thickness allowing it to be embedded in a tiled structure without having to create a pit.
• the profiles have an H-shaped cross-section with lateral flanges. Perforated at the bottom to allow the cable to pass through. Spacers are positioned between the profiles to maintain the spacing.
• This type of mat has an open structure allowing dirt to fall to the bottom of the pit, between the profiles.
• this type of mat is not available in thicknesses less than 10 mm and therefore cannot be embedded in a tiled surface without creating a pit. Its manufacture is complex, requiring holes to be drilled in the aluminum profiles and the steel cables to be manually threaded through these holes. It also has limited resistance to heavy loads, which can lift the cable and damage the spacers.
• the profiles also have an H-shaped section with lateral wings, the lower end part of which includes a snap-fit groove for the rod.
• the construction of the state-of-the-art rush conveyor does not allow for a thickness less than 10 mm. It also has limited resistance to heavy loads.
• One of the aims of the invention is to overcome the disadvantages of the prior art, by proposing an aluminium profile for a floor mat which is improved to allow the same profile to be used to create a mat whose profiles can be connected to each other by a polymer mat, or by cables or PVC rods, while easily adapting its thickness to fit any type of pit to be made, or already existing.
• the invention seeks in particular to offer a modular mat that can adapt to different types of installation, different pit depths, traffic intensity and several levels of resistance to load passages.
• an aluminium profile of a modular floor mat has been developed; the profile includes means of connection to an adjacent profile and an upper portion receiving a coating element, such as a scraping or drying insert.
• the aluminum profile according to the invention makes it possible to create a modular floor mat that can be mounted according to three different mounting techniques, with the same profile, namely a mounting with profiles glued onto a polymer mat, with profiles connected by PVC or rubber rods, or with profiles connected by cables.
• the invention allows the mat thickness to be adapted according to the type of installation or the depth of an existing pit.
• the presence of a base with a width at least equal to 50% of the profile width provides stable support for the profile and improves resistance to heavy loads, thus reducing the required aluminum thickness and the profile's weight.
• the profiles of the carpet according to the invention can be made up of walls with thicknesses between 1 mm and 1.5 mm, for example 1.2 mm.
• the base and the web of each profile define at least one closed section between them, and for example several adjacent sections closed and separated by a wall, preferably vertical, so as to increase the rigidity and resistance to traffic of the profile.
• the base is connected to the core by a vertical wall.
• the vertical wall and base together create a kind of foot that promotes the rigidity and resistance to traffic of the profile, while having an open structure that limits the weight of the profile.
• the profile has a height between 7 and 25 mm, preferably between 9 and 18 mm.
• the invention therefore also relates to a modular floor mat comprising a plurality of aluminium profiles according to one of the aforementioned characteristics, arranged and linked parallel to each other.
• the mat includes an accessory that is snapped into at least one extreme groove of an end profile, such as an inclined ramp that forms, for example, a door threshold, or a cuttable insert to fit a determined pit width.
• an accessory that is snapped into at least one extreme groove of an end profile, such as an inclined ramp that forms, for example, a door threshold, or a cuttable insert to fit a determined pit width.
• the cuttable insert includes thinner, weakened areas to facilitate cutting the insert to the correct size.
• the invention relates to a modular mat (1) laid on the ground in free laying, for example in a pit, or to be sealed in a structure.
• the floor mat (1) includes improved profiles (2) enabling it to adapt to different types of installation, pit or structure depth, or different types of assembly depending on the constraints of use, in particular the traffic to be withstood.
• the floor mat (1) comprises a plurality of aluminium profiles (2) arranged and connected parallel to each other, preferably with a spacing between them of 4 to 7 mm, preferably 5 to 6 mm.
• Each profile (2) has a width between 30 mm and 50 mm, preferably between 35 and 45 mm, and includes means for connecting to an adjacent profile (2) and an upper portion receiving a coating element (3), such as a scraping and/or drying insert.
• the covering element (3) can be made of looped textile, for example 100% polypropylene, of velvet, for example 100% polyamide, or of rubber.
• the improved profiles (2) include a general section at least in the shape of an H, so as to define a web (4), in particular horizontal, for receiving the insert, and two wings (5), in particular lateral and vertical, for edging and holding the insert.
• each wing (5) can include a A longitudinal groove (16), for example a barleycorn groove, guides a drill bit and facilitates the creation of cable entry holes.
• the lower end portion of each wing (5) includes a snap-fit groove (6) for a connecting rod to an adjacent profile or an accessory such as a ramp.
• this groove (6) is formed by U-shaped profiled walls, the free ends of which are curved inwards to create the snap-fit effect.
• Each profile (2) includes, in addition to the H-shaped section, a base (7) parallel to the web and spaced from it, preferably by a distance greater than 3 mm, so as to define a space allowing the cables (8) to run, the width of the base (7) being at least equal to 50% of the width of the aluminium profile (2), preferably at least equal to 70%, or even 80% or 90%.
• the spacing between the core (4) and the base (7), and the height of the profiles (2), are chosen, for example, according to the depth of the pit in which the mat (1) is to be installed, particularly if it involves replacing a worn mat in an existing pit.
• the profiles (2) typically have a height between 7 and 25 mm, preferably between 9 and 18 mm. The fact that the profiles (2) can be less than 10 mm high makes the mat (1) suitable for installation embedded in a structure, for example.
• the base (7) in contact with the ground or the bottom of the pit, provides stable support for the profile (2) and improves resistance to heavy loads, thus reducing the required aluminum thickness and consequently the weight of the profile and the mat.
• the profiles (2) can therefore have walls with thicknesses between 1 and 1.5 mm.
• a strip (9) of foam or elastomer can be glued under the base (7) to cushion, protect the profile (2), and provide acoustic insulation.
• the base (7) is connected to the flanges (5) or to the web (4) so as to define at least one closed section, or even several adjacent closed sections separated by a wall (10), for example vertical, connecting the base (7) and the web (4) to increase resistance to heavy loads.
• the resulting profile (2) is therefore hollow.
• the base (7) is connected to the core (4) by three vertical walls (10) to form a hollow profile with two closed sections, including a central vertical wall and two lateral vertical walls which, together with the wings (5), form the lateral walls of the U-shaped snap grooves (6).
• the base and the web do not form a closed section, but the base and the web are connected by a vertical wall, so as to form a kind of feet creating a stable and rigid support for the profile and also increasing resistance to heavy loads.
• the wall(s) (10) connecting the base (7) and the core (4) are of course also pierced to allow the cables (8) to pass through.
• the floor mat (1) may include an accessory that is snapped into at least one end groove (6) of an end profile, such as an inclined ramp or a cuttable insert (11) to fit a specified pit width.
• the cuttable insert (11) is presented for example in the form of a parallelepiped block of plastic or rubber with a lateral, longitudinal and upward-oriented tab to snap into the groove (6) of the profile, and with weakened areas of lesser thickness, in particular provided over the entire length of the block, to facilitate cutting the insert.
• the profiles (2) are connected to each other with their base (7) glued onto a polymeric film, such as PET, PVC, PP, or PMMA, or any other polymer, with a double-sided adhesive or a hot melt glue.
• a polymeric film such as PET, PVC, PP, or PMMA, or any other polymer
• the profiles (2) are connected to each other by PVC or rubber rods (12) which are snapped into the snap grooves (6).
• the rods (12) have two longitudinal lateral tabs oriented upwards for this purpose to snap into the grooves (6) of two adjacent profiles.
• the profiles (2) are drilled and connected to each other by at least two cables (8), for example positioned at the two lateral ends of the mat, passing through the holes made in the lower parts of the wings (5), and running in the space defined between the web (4) and the base (7) of each profile (2).
• cables (8) are positioned along the length of the mat, for example one cable every 20 to 50 cm.
• the mat (1) preferably includes at least two PVC or rubber spacers (13) positioned between each pair of profiles (2). These spacers (13) are, for example, also drilled and passed through by the cables (8) in order to simplify assembly and hold the spacers (13) in position.
• the cable (8) includes, for example, at a first end a head (14) wider than the opening of a wall (10) of a first end profile to butt against said wall and, at an opposite end, an added stop (15) to lock the cable (8) by providing counter-support against a wall (10) of a last end profile of the mat.
