Definitions
- the present invention relates to the field of floor coverings and more particularly to a floor panel for producing a floor covering or the like, said panel having the shape of a blade and/or slab and being made of a plastic material such as PVC.
- the document UK 2,256,023 describes a joint between the adjacent side edges of two similar panels, in which one panel comprises a U-shaped cross-section groove opening on the side of the panel and a second panel comprises a side tab comprising a rib facing the underside of the panel, said tongue cooperating with the groove in order to limit the separation of the panels.
- the document EP 1 026 341 describes a hard floor panel for providing floor covering.
- This floor panel comprises two edges on two opposite sides provided with coupling elements which give two adjacent panels the ability to cooperate with each other, said coupling elements being essentially in the form of a tongue and a groove.
- Said coupling means are provided with integrated mechanical locking means made in one piece with the panel so that, when two adjacent panels are coupled, said means prevent said panels from moving away from each other in a direction perpendicular to the relevant edges and parallel to the underside of the mated floor panels.
- WO 2012/004701 describes a floor panel comprising a substrate and an upper layer placed on the substrate, the upper layer being composed of at least one print and a transparent thermoplastic layer, said floor panel being provided, on at least two opposite edges, a straight or curved chamfer. Furthermore, two opposite edges of a panel respectively comprise a U-shaped cross-section groove opening onto the side of the panel and a lateral tab capable of cooperating with the groove in order to limit the separation of the panels.
- the document EP 1 190 149 discloses a fastening system for panels with retaining profiles that can be arranged on the narrow sides of the panels where opposing retaining profiles of one panel fit together so that adjacent panels can be attached to each other.
- Said holding profiles consist of a so-called proximal groove opening onto the lower face of the panel and respectively onto the upper face of the panel, and of a hook-shaped distal tab, said hook being oriented towards the groove, extending at the end of the edge of the panel towards the lower face and respectively towards the upper face of said panel so that, during assembly, the hook-shaped tongue of a first panel cooperates with the hook-shaped tongue of a second adjacent panel.
- this type of panel requires a smaller free space given the fact that the assembly is done vertically, this type of panel nevertheless has the disadvantage of requiring a high force for assembly and low resistance to unclipping.
- the distal flexible tongue of the female coupling means moves apart by elasticity to allow the distal flexible tongue of the male coupling means to penetrate into the proximal groove of the female coupling means.
- the spacing of the tongue is done against bearing against the ground so that a force opposing the clipping is exerted on the flexible tongue of the male coupling means, which is in particular transmitted to the lug of clipping.
- One of the aims of the invention is therefore to remedy this drawback by proposing a floor panel of simple and inexpensive design, limiting the inconvenience for the installer in his manipulations for the installation of panels and in particular near areas of corners or walls, making it easier to adjust the position of the panels between them once assembled, and ensuring perfect reliability in the holding of the assembly, the panels being all in the same plane after assembly and with no upper or lower overflow with respect to their upper and lower external surfaces.
- Another object of the invention is to facilitate the assembly/disassembly of two adjacent panels, while avoiding the risk of damage to the clipping lugs.
- the invention proposes a floor panel as defined by claim 1, having the shape of a blade and/or slab and being made of a plastic material for the production of a floor covering or the like.
- the panel comprises at least two pairs of opposite sides defining two adjacent edges comprising male coupling means, and two opposite adjacent edges comprising female coupling means.
- the assembly kinematics of these panels is vertical.
- the male coupling means consist of at least one so-called proximal groove opening onto a lower face of the panel and of a flexible distal tongue extending at the end of the edge of the panel towards the lower face of said panel.
- the female coupling means consist of at least one proximal groove opening onto an upper face of the panel and of a flexible tongue extending at the end of the edge of the panel, towards the upper face of said panel.
- the flexible distal tongue of the male coupling means has a proximal wall inclined at an angle ⁇ with respect to a vertical plane downwards and towards the outside of the panel.
- the flexible tongue of the female coupling means has a proximal wall inclined at an angle ⁇ with respect to a vertical plane upwards and outwards from the panel.
- the distal tab of at least one of the male or female coupling means has a distal wall comprising at least one lug or a notch capable of cooperating with a notch or a lug made on a proximal wall that the proximal groove has corresponding female or male coupling means to form a stopper, preventing a vertical displacement of a panel with respect to the adjacent panel.
- the flexible tongue of the female coupling means has a bottom wall comprising a chamfered part forming an angle of between 2° and 20°, and preferably 10° with respect to the main plane of the panel.
- This chamfered part provides a reduction in the clipping force so that it is easier to assemble two adjacent panels.
- this range of values of the angle of the chamfered part makes it possible to produce a recess of material over substantially the entire width of the flexible tongue.
- the chamfered part of the flexible tongue is not in contact with the ground so that, during clipping, the tongue pivots until the chamfered part comes to rest on the ground in thus limiting the forces opposing clipping. In this way, it is easier to assemble two adjacent panels, and the risks of damaging the lug are reduced.
- the presence of the chamfer allows deformation and mobility of the flexible tongue, one then speaks of a deformable flexible tongue.
- the distal walls of the deformable distal tongues of the male and female coupling means respectively comprise a lug and a notch capable of cooperating with a notch and a lug respectively formed on the proximal walls of the proximal grooves of the coupling means corresponding females and males to form a stopper, preventing a vertical displacement of a panel with respect to the adjacent panel.
- angles ⁇ and ⁇ are between 1 and 45°, and preferably between 5° and 15°. According to a particular embodiment, the angle ⁇ is equal to the angle ⁇ .
- the distal wall of the deformable flexible tongue of the female coupling means comprises two parts, an upper part inclined at an angle of between 1° and 20° relative to the vertical and a lower part also inclined at a angle between 1° and 20° from the vertical.
- the upper and lower parts extend parallel on either side of the notch or respectively of the lug.
- the proximal wall of the proximal groove of the male coupling means also comprises two parts, an upper part inclined at an angle between 1° and 20° relative to the vertical and an upper lower part inclined at an angle between 1° and 20° from the vertical.
- Said upper and lower parts extend parallel on either side of the lug capable of cooperating with the notch capable of cooperating with the notch or respectively of the notch capable of cooperating with the lug, in order to improve clipping.
- the proximal wall of the proximal groove of the female coupling means is inclined at an angle comprised between 1 and 45°, and preferably between 5° and 15° with respect to a vertical plane.
- the flexible deformable tongue and the proximal groove of the male coupling means, and the flexible deformable tongue and the proximal groove of the female coupling means are inclined towards the exterior of the panel.
- the inclinations favor the deformation of the deformable distal tongue of the male coupling means and of the flexible deformable tongue of the female coupling means limiting, during vertical clipping, the friction of the lug of the coupling means males on the proximal wall of the proximal groove of the female coupling means as well as the friction of the lug of the male coupling means on the distal wall of the tongue of the female coupling means.
- Clipping is not completely vertical but is inclined at an angle to a vertical plane. This thus makes it possible to have better dimensioned lugs, to preserve said lugs from friction, and therefore to reduce the clipping forces and the risks of deterioration.
- the inclinations favor, during unclipping, the transfer of the shearing forces perceived by the lugs into torsion/compression forces in all the profiles of the male and female coupling means, thus increasing the unclipping forces.
- the distal and proximal walls of the deformable flexible tabs of the male and female coupling means are parallel and respectively inclined at an angle to a vertical plane, and the proximal walls of the proximal grooves of the male and female coupling means are parallel to the proximal walls respectively of the flexible tabs deformable male and female coupling means.
- the underside of the floor panel comprises a chamfered part opening onto the proximal groove, forming an angle of between 2° and 20°, and preferably 10° with respect to the main plane of the panel, said chamfered part allowing the lowering of the panel during clipping to come, by deformation, into contact with the ground and thus promote the viability of said clipping.
- the same reference numerals designate the same elements.
- the various views are not necessarily drawn to scale.
- the floor panels described below are preferably obtained in plasticized PVC and comprising a mineral filler; however, it is obvious that the floor panels can be obtained in any plastic material.
- Each floor panel (1) includes two pairs of opposite sides defining the edges of the panel. Two adjacent edges comprise male coupling means (2) while two opposite adjacent edges comprise female coupling means (3).
- the assembly kinematics of two panels (1) is vertical according to a force (F).
- Said male coupling means (2) consist of a so-called proximal groove (4) opening onto an underside of the panel (1) and of a distal tongue (5) extending at the end of the edge of the panel (1) towards the underside of said panel (1).
- the distal tab (5) has a substantially rectangular cross section.
- Said female coupling means (3) consist of a proximal groove (6) of substantially rectangular cross-section, opening onto an upper face of the panel (1) and of a deformable flexible tongue (7) extending to the end of the edge of the panel (1), towards the upper face of said panel (1).
- the deformable flexible tongue (7) has a proximal wall inclined upwards and towards the outside of the panel (1) at an angle ( ⁇ ) with respect to the vertical plane, so that the distal tongue (5) of the means of male coupling (2), is introduced into the proximal groove (6) of the female coupling means (3) at an angle by resting on the deformable flexible tongue (7) which deforms to allow the introduction of the distal tongue ( 5) in the proximal groove (6).
- the distal tongue (5) also deforms during its insertion into the proximal groove (6).
- the proximal wall of the deformable flexible tab (7) is inclined upwards and outwards from the panel (1) at an angle ( ⁇ ) of between 1° and 45° relative to the vertical, and preferably, along an angle ( ⁇ ) of between 5° and 15° with respect to the vertical.
- the proximal groove (4) of the male coupling means (2) has a proximal wall inclined downwards and towards the outside of the panel (1) at an angle ( ⁇ ) with respect to the vertical plane of said panel ( 1).
- Said angle ( ⁇ ) is between 1° and 45° and, preferably, between 5° and 15°.
- the angle ( ⁇ ) is substantially equal to the angle ( ⁇ ). It is obvious that the angle ( ⁇ ) may be different from the angle ( ⁇ ) without departing from the scope of the invention.
- the distal tongue (5) of the male coupling means (2) has a distal wall comprising at least one lug (11) capable of cooperating with a notch (12) made on a proximal wall that the groove has.
- the deformable flexible tongue (7) has a bottom wall comprising a chamfered part (13) forming an angle of between 2° and 20°, preferably 10° with respect to the main plane of the panel (1).
- This chamfered part (13) provides a reduction in the clipping force so that it is easier to assemble two adjacent panels.
- the clipping force of the floor panel according to the invention is markedly lower than the clipping force of a floor panel having no chamfered part. This chamfered part (13) limits the clipping forces and allows a more suitable dimensioning of the lug (11).
- This range of values of the angle of the chamfered part (13) makes it possible to produce a recess of material over substantially the entire width of the deformable flexible tongue (7).
- the chamfered part (13) of the deformable flexible tongue (7) is not in contact with the ground so that, during clipping, the tongue (7) pivots until that the chamfered part (13) comes to rest on the ground, thus limiting the forces opposing clipping. In this way, it is easier to assemble two adjacent panels, and the risks of damaging the lug (11) are reduced.
- the deformable flexible tongue (7) has a distal wall comprising two parts, namely, an upper part inclined relative to the vertical at an angle of between 1° and 45°, and preferably between 1° and 20° and a lower part extending vertically.
- the proximal wall of the proximal groove (4) also comprises two parts, namely, an upper part inclined relative to the vertical at an angle of between 1° and 45°, and preferably between 1° and 20° in order to improve the unclipping, and a lower part extending vertically, in order to improve the clipping.
- the underside of the floor panel (1) may also comprise a chamfered part (14) opening onto the proximal groove (4), and forming an angle of between 2° and 20°, ideally 10° with respect to the main plane of the panel (1).
- This chamfered part (14) allows the lowering of the panel (1) during clipping to come, by deformation, into contact with the ground and thus promote the viability of said clipping.
- the distal wall of the flexible deformable tongue (7) also comprises an upper part inclined at an angle of between 1° and 20° relative to the vertical and a lower part also inclined at an angle of between 1° and 20° from the vertical.
- the upper and lower parts extend parallel on either side of a notch (15).
- the proximal wall of the proximal groove (4) also has two parts, an upper part inclined at an angle between 1° and 20° relative to the vertical, and a lower part inclined at an angle between 1° and 20° relative to the vertical.
- the upper and lower parts extend parallel on either side of a shoulder forming a lug (16) capable of cooperating with the notch (15), in order to improve clipping.
- the clipping force of the floor panels according to the invention is slightly lower than the clipping force of the panels of the prior art during the first millimeters of engagement of the male and female parts, and that the force unclipping is significantly greater than that of the panels of the prior art.
- the orientation at an angle of between 1° and 45°, and preferably between 5° and 15° relative to the vertical of the proximal walls of the tongues (5, 7) of the male coupling means (2) and female (3) provides an opening of the male (2) and female (3) parts during clipping so that the lug (11) does not rub on the proximal wall of the proximal groove (6) thus preserving the lug (11) and reducing the clipping forces.
- this orientation at an angle of between 1° and 45°, and preferably between 5° and 15° relative to the vertical of the proximal walls of the tongues (5, 7) of the male coupling means (2) and female (3) makes it possible to transfer the shearing force of the lug in compression/torsion in all the profiles of the male (2) and female (3) parts increasing the unclipping forces.
- the deformable flexible distal tongue (5) and the proximal groove (4) of the male coupling means (2), and the deformable flexible tongue (7) and the proximal groove (6) of the female couplings (3) are inclined towards the outside of the panel (1).
- the deformable flexible distal tongues (5, 7) comprise distal walls substantially parallel to their proximal walls and are in particular inclined respectively at an angle ( ⁇ , ⁇ ) relative to a vertical plane towards the outside of the sign.
- the proximal grooves (4, 6) comprise proximal walls substantially parallel to the proximal walls respectively deformable flexible tongues (5, 7).
- the inclinations favor the deformation of the deformable flexible distal tongue (5) of the male coupling means (2) and of the deformable flexible tongue (7) of the female coupling means (3) limiting, during clipping vertical, the friction of the lug (11) of the male coupling means (2) on the proximal wall of the proximal groove (6) of the female coupling means (3) as well as the friction of the lug (16 ) male coupling means (2) on the distal wall of the tongue (7) female coupling means (3) thus making it possible to have better sized lugs, to preserve said lugs from friction, and therefore to reduce the clipping forces, as illustrated in figure 17 .
- said inclinations favor, during unclipping, the transfer of the shear forces perceived by the lugs into torsion/compression forces in all the profiles of the male (2) and female (3) parts, thus increasing the forces of unclipping, as shown in figure 18 .

- the lug (11, 16) and the notch (12, 15) can be provided only on one of the coupling means (2, 3), or on both without leaving the frame of the invention.
- the deformable flexible distal tongue (5) of the male coupling means (2) comes into contact with the deformable flexible tongue (7) of the coupling means (3), this contact causes deformation of the deformable flexible distal tongue (5) of the male coupling means (2) as well as the deformation of the deformable flexible tongue (7) of the female coupling means (3), this deformation allows the introduction of the deformable flexible distal tongue (5) of the male coupling means (2) into the proximal groove (6) of the female coupling (3) as well as the introduction of the deformable flexible tongue (7) of the female coupling means (3) into the proximal groove (4) of the male coupling means (2).

Il est bien connu de réaliser des revêtements de sols à partir d'éléments modulaires sous forme de lames et/ou de dalles. Leur fixation au sol s'effectue usuellement par une opération de collage et/ou par un assemblage en emboitement des lames et/ou des dalles présentant des moyens mâles-femelles de liaison ou d'assemblage.It is well known to produce floor coverings from modular elements in the form of strips and/or tiles. They are fixed to the ground usually by a bonding operation and/or by an interlocking assembly of the blades and/or tiles having male-female connection or assembly means.

L'assemblage de ce type de panneaux s'effectue par une présentation en oblique d'un panneau destiné à être positionné, qui est présenté dans une position vers le panneau d'ancrage, qui aboutit dans un plan horizontal pour être verrouillé et en alignement au précédent. Cela suggère des formes particulières et aussi un espace libre pour permettre l'amplitude du mouvement nécessaire à la pose des panneaux successifs.The assembly of this type of panels is carried out by an oblique presentation of a panel intended to be positioned, which is presented in a position towards the anchoring panel, which ends in a horizontal plane to be locked and in alignment. to the previous one. This suggests particular shapes and also a free space to allow the amplitude of the movement necessary for the installation of the successive panels.
On connait également de très nombreux brevets décrivant des moyens mâles-femelles d'assemblage de panneaux constitutifs de revêtements avec un pré positionnement en oblique ou en latéral en vue d'une insertion des moyens d'assemblage entre eux. C'est le cas notamment des demandes de brevet international
Ce type de panneaux présente les mêmes inconvénients lors de la pose et, pour pallier ces inconvénients, il a déjà été imaginé des panneaux comprenant des moyens d'accouplement mâles-femelles permettant un assemblage vertical des panneaux. C'est le cas notamment de la demande de brevet européen

Bien que ce type de panneau nécessite un espace libre plus restreint compte tenu du fait que l'assemblage se fait verticalement, ce type de panneau présente néanmoins l'inconvénient de nécessiter une force importante pour l'assemblage et une faible résistance au déclippage.Although this type of panel requires a smaller free space given the fact that the assembly is done vertically, this type of panel nevertheless has the disadvantage of requiring a high force for assembly and low resistance to unclipping.

En effet, lors du clippage des moyens d'accouplement mâles dans les moyens d'accouplement femelles, la languette flexible distale des moyens d'accouplement femelles s'écarte par élasticité pour laisser pénétrer la languette flexible distale des moyens d'accouplement mâles dans la rainure proximale des moyens d'accouplement femelles. Cependant, l'écartement de la languette se fait en contre-appui contre le sol de sorte qu'une force s'opposant au clippage est exercée sur la languette flexible des moyens d'accouplement mâles, qui est notamment transmise à l'ergot de clippage.In fact, when clipping the male coupling means into the female coupling means, the distal flexible tongue of the female coupling means moves apart by elasticity to allow the distal flexible tongue of the male coupling means to penetrate into the proximal groove of the female coupling means. However, the spacing of the tongue is done against bearing against the ground so that a force opposing the clipping is exerted on the flexible tongue of the male coupling means, which is in particular transmitted to the lug of clipping.
L'un des buts de l'invention est donc de remédier à cet inconvénient en proposant un panneau de sol de conception simple et peu onéreuse, limitant la gêne pour le poseur dans ses manipulations pour la pose de panneaux et en particulier près des zones d'angles ou de murs, facilitant le réglage en position des panneaux entre eux une fois assemblés, et assurant une parfaite fiabilité dans la tenue de l'assemblage, les panneaux étant tous dans le même plan après assemblage et sans débordement supérieur ou inférieur par rapport à leurs surfaces externes supérieure et inférieure.One of the aims of the invention is therefore to remedy this drawback by proposing a floor panel of simple and inexpensive design, limiting the inconvenience for the installer in his manipulations for the installation of panels and in particular near areas of corners or walls, making it easier to adjust the position of the panels between them once assembled, and ensuring perfect reliability in the holding of the assembly, the panels being all in the same plane after assembly and with no upper or lower overflow with respect to their upper and lower external surfaces.
Un autre objectif de l'invention est de faciliter l'assemblage/désassemblage de deux panneaux adjacents, tout en évitant les risques de détérioration des ergots de clippage.Another object of the invention is to facilitate the assembly/disassembly of two adjacent panels, while avoiding the risk of damage to the clipping lugs.
A cet effet, l'invention propose un panneau de sol tel que défini par la revendication 1, ayant une forme de lame et/ou de dalle et étant réalisé dans une matière plastique pour la réalisation d'un revêtement de sol ou similaire. D'une manière connue, le panneau comprend au moins deux paires de côtés opposés définissant deux bords adjacents comprenant des moyens d'accouplement mâles, et deux bords adjacents opposés comprenant des moyens d'accouplement femelles. La cinématique d'assemblage de ces panneaux est verticale.To this end, the invention proposes a floor panel as defined by
Les moyens d'accouplement mâles sont constitués d'au moins une rainure dite proximale débouchant sur une face inférieure du panneau et d'une languette distale flexible s'étendant à l'extrémité du bord du panneau vers la face inférieure dudit panneau.The male coupling means consist of at least one so-called proximal groove opening onto a lower face of the panel and of a flexible distal tongue extending at the end of the edge of the panel towards the lower face of said panel.
Les moyens d'accouplement femelles sont constitués d'au moins une rainure proximale débouchant sur une face supérieure du panneau et d'une languette flexible s'étendant à l'extrémité du bord du panneau, vers la face supérieure dudit panneau.The female coupling means consist of at least one proximal groove opening onto an upper face of the panel and of a flexible tongue extending at the end of the edge of the panel, towards the upper face of said panel.
La languette distale flexible des moyens d'accouplement mâles présente une paroi proximale inclinée suivant un angle β par rapport à un plan vertical vers le bas et vers l'extérieur du panneau.The flexible distal tongue of the male coupling means has a proximal wall inclined at an angle β with respect to a vertical plane downwards and towards the outside of the panel.
La languette flexible des moyens d'accouplement femelles présente une paroi proximale inclinée suivant un angle α par rapport à un plan vertical vers le haut et vers l'extérieur du panneau.The flexible tongue of the female coupling means has a proximal wall inclined at an angle α with respect to a vertical plane upwards and outwards from the panel.
La languette distale de l'un au moins des moyens d'accouplement mâles ou femelle présente une paroi distale comportant, au moins, un ergot ou une encoche apte à coopérer avec une encoche ou un ergot pratiqué sur une paroi proximale que présente la rainure proximale des moyens d'accouplement femelles ou mâle correspondant pour former une butée d'arrêt, évitant un déplacement vertical d'un panneau par rapport au panneau adjacent.The distal tab of at least one of the male or female coupling means has a distal wall comprising at least one lug or a notch capable of cooperating with a notch or a lug made on a proximal wall that the proximal groove has corresponding female or male coupling means to form a stopper, preventing a vertical displacement of a panel with respect to the adjacent panel.
Il résulte de ces caractéristiques que le fait que la paroi proximale de la languette flexible soit orientée permet de limiter les efforts de clippage et de favoriser le transfert d'effort pour l'action de déclippage.It follows from these characteristics that the fact that the proximal wall of the flexible tongue is oriented makes it possible to limit the clipping forces and to promote the transfer of force for the unclipping action.
Selon l'invention, la languette flexible des moyens d'accouplement femelles présente une paroi inférieure comportant une partie chanfreinée formant un angle compris entre 2° et 20°, et de préférence 10° par rapport au plan principal du panneau. Cette partie chanfreinée procure une réduction de l'effort de clippage de sorte qu'il est plus aisé d'assembler deux panneaux adjacents.According to the invention, the flexible tongue of the female coupling means has a bottom wall comprising a chamfered part forming an angle of between 2° and 20°, and preferably 10° with respect to the main plane of the panel. This chamfered part provides a reduction in the clipping force so that it is easier to assemble two adjacent panels.
En effet, cette plage de valeur de l'angle de la partie chanfreinée permet de réaliser un évidement de matière sur sensiblement toute la largeur de la languette flexible. Ainsi, avant clippage de deux panneaux adjacents, la partie chanfreinée de la languette flexible n'est pas en contact avec le sol de sorte que, lors du clippage, la languette pivote jusqu'à ce que la partie chanfreinée vienne reposer sur le sol en limitant ainsi les efforts s'opposant au clippage. De cette manière, il est plus aisé d'assembler deux panneaux adjacents, et les risques de détériorer l'ergot sont diminués. La présence du chanfrein permet une déformation et une mobilité de la languette flexible, on parle alors de languette flexible déformable.Indeed, this range of values of the angle of the chamfered part makes it possible to produce a recess of material over substantially the entire width of the flexible tongue. Thus, before clipping of two adjacent panels, the chamfered part of the flexible tongue is not in contact with the ground so that, during clipping, the tongue pivots until the chamfered part comes to rest on the ground in thus limiting the forces opposing clipping. In this way, it is easier to assemble two adjacent panels, and the risks of damaging the lug are reduced. The presence of the chamfer allows deformation and mobility of the flexible tongue, one then speaks of a deformable flexible tongue.
Selon l'invention, les parois distales des languettes distales déformables des moyens d'accouplement mâles et femelles comportent respectivement un ergot et une encoche apte à coopérer avec une encoche et un ergot respectivement pratiqués sur les parois proximales des rainures proximales des moyens d'accouplement femelles et mâles correspondant pour former une butée d'arrêt, évitant un déplacement vertical d'un panneau par rapport au panneau adjacent.According to the invention, the distal walls of the deformable distal tongues of the male and female coupling means respectively comprise a lug and a notch capable of cooperating with a notch and a lug respectively formed on the proximal walls of the proximal grooves of the coupling means corresponding females and males to form a stopper, preventing a vertical displacement of a panel with respect to the adjacent panel.
De préférence, les angles α et β sont compris entre 1 et 45°, et de préférence entre 5° à 15°. Selon une forme de réalisation particulière, l'angle α est égal à l'angle β.Preferably, the angles α and β are between 1 and 45°, and preferably between 5° and 15°. According to a particular embodiment, the angle α is equal to the angle β.
Selon l'invention, la paroi distale de la languette flexible déformable des moyens d'accouplement femelles comporte deux parties, une partie supérieure inclinée suivant un angle compris entre 1 ° et 20° par rapport à la verticale et une partie inférieure également inclinée suivant un angle compris entre 1° et 20° par rapport à la verticale. Les parties supérieure et inférieure s'étendent parallèlement de part et d'autre de l'encoche ou respectivement de l'ergot. La paroi proximale de la rainure proximale des moyens d'accouplement mâles comporte également deux parties, une partie supérieure inclinée suivant un angle compris entre 1° et 20° par rapport à la verticale et une partie inférieure supérieure inclinée suivant un angle compris entre 1° et 20° par rapport à la verticale. Lesdites parties supérieure et inférieure s'étendent parallèlement de part et d'autre de l'ergot apte à coopérer avec l'encoche apte à coopérer avec l'encoche ou respectivement de l'encoche apte à coopérer avec l'ergot, afin d'améliorer le clippage. De préférence, la paroi proximale de la rainure proximale des moyens d'accouplement femelles est inclinée suivant un angle compris entre 1 et 45°, et de préférence entre 5° à 15° par rapport à un plan vertical.According to the invention, the distal wall of the deformable flexible tongue of the female coupling means comprises two parts, an upper part inclined at an angle of between 1° and 20° relative to the vertical and a lower part also inclined at a angle between 1° and 20° from the vertical. The upper and lower parts extend parallel on either side of the notch or respectively of the lug. The proximal wall of the proximal groove of the male coupling means also comprises two parts, an upper part inclined at an angle between 1° and 20° relative to the vertical and an upper lower part inclined at an angle between 1° and 20° from the vertical. Said upper and lower parts extend parallel on either side of the lug capable of cooperating with the notch capable of cooperating with the notch or respectively of the notch capable of cooperating with the lug, in order to improve clipping. Preferably, the proximal wall of the proximal groove of the female coupling means is inclined at an angle comprised between 1 and 45°, and preferably between 5° and 15° with respect to a vertical plane.
De préférence, la languette flexible déformable et la rainure proximale des moyens d'accouplement mâles, et la languette flexible déformable et la rainure proximale des moyens d'accouplement femelles sont inclinées vers l'extérieur du panneau.Preferably, the flexible deformable tongue and the proximal groove of the male coupling means, and the flexible deformable tongue and the proximal groove of the female coupling means are inclined towards the exterior of the panel.
De cette manière, les inclinaisons favorisent la déformation de la languette distale déformable des moyens d'accouplement mâles et de la languette flexible déformable des moyens d'accouplement femelles limitant, lors du clippage vertical, les frottements de l'ergot des moyens d'accouplement mâles sur la paroi proximale de la rainure proximale des moyens d'accouplement femelles ainsi que les frottements de l'ergot des moyens d'accouplement mâles sur la paroi distale de la languette des moyens d'accouplement femelles. Le clippage n'est pas totalement vertical mais est incliné selon un angle par rapport à un plan vertical. Ceci permet ainsi d'avoir des ergots mieux dimensionnés, de préserver lesdits ergots du frottement, et donc de réduire les efforts de clippage et les risques de détérioration.In this way, the inclinations favor the deformation of the deformable distal tongue of the male coupling means and of the flexible deformable tongue of the female coupling means limiting, during vertical clipping, the friction of the lug of the coupling means males on the proximal wall of the proximal groove of the female coupling means as well as the friction of the lug of the male coupling means on the distal wall of the tongue of the female coupling means. Clipping is not completely vertical but is inclined at an angle to a vertical plane. This thus makes it possible to have better dimensioned lugs, to preserve said lugs from friction, and therefore to reduce the clipping forces and the risks of deterioration.
De plus, les inclinaisons favorisent, lors du déclippage, le transfert des efforts de cisaillement perçus par les ergots en efforts de torsion/compression dans l'ensemble des profils des moyens d'accouplement mâles et femelles, augmentant ainsi les efforts de déclippage.In addition, the inclinations favor, during unclipping, the transfer of the shearing forces perceived by the lugs into torsion/compression forces in all the profiles of the male and female coupling means, thus increasing the unclipping forces.
Selon une forme de réalisation particulière, les parois distales et proximales des languettes flexibles déformables des moyens d'accouplement mâles et femelles sont parallèles et inclinées respectivement selon un angle par rapport à un plan vertical, et les parois proximales des rainures proximales des moyens d'accouplement mâles et femelles sont parallèles aux parois proximales respectivement des languettes flexibles déformables des moyens d'accouplement mâles et femelles.According to a particular embodiment, the distal and proximal walls of the deformable flexible tabs of the male and female coupling means are parallel and respectively inclined at an angle to a vertical plane, and the proximal walls of the proximal grooves of the male and female coupling means are parallel to the proximal walls respectively of the flexible tabs deformable male and female coupling means.
Par ailleurs, avantageusement, la face inférieure du panneau de sol comporte une partie chanfreinée débouchant sur la rainure proximale, formant un angle compris entre 2° et 20°, et de préférence 10° par rapport au plan principal du panneau, ladite partie chanfreinée autorisant l'abaissement du panneau lors du clippage pour venir, par déformation, en contact avec le sol et ainsi favoriser la viabilité dudit clippage.Furthermore, advantageously, the underside of the floor panel comprises a chamfered part opening onto the proximal groove, forming an angle of between 2° and 20°, and preferably 10° with respect to the main plane of the panel, said chamfered part allowing the lowering of the panel during clipping to come, by deformation, into contact with the ground and thus promote the viability of said clipping.

Dans la suite de la description du panneau de sol suivant l'invention, les mêmes références numériques désignent les mêmes éléments. Par ailleurs, les différentes vues ne sont pas nécessairement tracées à l'échelle. De plus, les panneaux de sols décrits ci-après sont de préférence obtenus dans du PVC plastifié et comportant une charge minérale ; toutefois, il est bien évident que les panneaux de sols pourront être obtenus dans toute matière plastique.In the following description of the floor panel according to the invention, the same reference numerals designate the same elements. Furthermore, the various views are not necessarily drawn to scale. In addition, the floor panels described below are preferably obtained in plasticized PVC and comprising a mineral filler; however, it is obvious that the floor panels can be obtained in any plastic material.
Chaque panneau de sol (1) comprend deux paires de côtés opposés définissant les bords du panneau. Deux bords adjacents comprennent des moyens d'accouplement mâles (2) tandis que deux bords adjacents opposés, comprennent des moyens d'accouplement femelles (3). La cinématique d'assemblage de deux panneaux (1) est verticale selon une force (F). Lesdits moyens d'accouplement mâles (2) sont constitués d'une rainure dite proximale (4) débouchant sur une face inférieure du panneau (1) et d'une languette distale (5) s'étendant à l'extrémité du bord du panneau (1) vers la face inférieure dudit panneau (1). La languette distale (5) présente une section transversale sensiblement rectangulaire. Lesdits moyens d'accouplement femelles (3) sont constitués d'une rainure proximale (6) de section transversale sensiblement rectangulaire, débouchant sur une face supérieure du panneau (1) et d'une languette flexible déformable (7) s'étendant à l'extrémité du bord du panneau (1), vers la face supérieure dudit panneau (1). La languette flexible déformable (7) présente une paroi proximale inclinée vers le haut et vers l'extérieur du panneau (1) suivant un angle (α) par rapport au plan vertical, de sorte que la languette distale (5) des moyens d'accouplement mâles (2), est introduite dans la rainure proximale (6) des moyens d'accouplement femelles (3) en biais en prenant appui sur la languette flexible déformable (7) qui se déforme pour permettre l'introduction de la languette distale (5) dans la rainure proximale (6). La languette distale (5) se déforme également lors de son introduction dans la rainure proximale (6).Each floor panel (1) includes two pairs of opposite sides defining the edges of the panel. Two adjacent edges comprise male coupling means (2) while two opposite adjacent edges comprise female coupling means (3). The assembly kinematics of two panels (1) is vertical according to a force (F). Said male coupling means (2) consist of a so-called proximal groove (4) opening onto an underside of the panel (1) and of a distal tongue (5) extending at the end of the edge of the panel (1) towards the underside of said panel (1). The distal tab (5) has a substantially rectangular cross section. Said female coupling means (3) consist of a proximal groove (6) of substantially rectangular cross-section, opening onto an upper face of the panel (1) and of a deformable flexible tongue (7) extending to the end of the edge of the panel (1), towards the upper face of said panel (1). The deformable flexible tongue (7) has a proximal wall inclined upwards and towards the outside of the panel (1) at an angle (α) with respect to the vertical plane, so that the distal tongue (5) of the means of male coupling (2), is introduced into the proximal groove (6) of the female coupling means (3) at an angle by resting on the deformable flexible tongue (7) which deforms to allow the introduction of the distal tongue ( 5) in the proximal groove (6). The distal tongue (5) also deforms during its insertion into the proximal groove (6).
La paroi proximale de la languette flexible déformable (7) est inclinée vers le haut et vers l'extérieur du panneau (1) suivant un angle (α) compris entre 1° et 45° par rapport à la verticale, et de préférence, suivant un angle (α) compris entre 5° et 15° par rapport à la verticale. Par ailleurs, la rainure proximale (4) des moyens d'accouplement mâles (2) présente une paroi proximale inclinée vers le bas et vers l'extérieur du panneau (1) suivant un angle (β) par rapport au plan vertical dudit panneau (1). Ledit angle (β) est compris entre 1° et 45° et, de préférence, compris entre 5° et 15°. Dans cet exemple particulier de réalisation, l'angle (α) est sensiblement égal à l'angle (β). Il est bien évident que l'angle (α) pourra être différent de l'angle (β) sans pour autant sortir du cadre de l'invention.The proximal wall of the deformable flexible tab (7) is inclined upwards and outwards from the panel (1) at an angle (α) of between 1° and 45° relative to the vertical, and preferably, along an angle (α) of between 5° and 15° with respect to the vertical. Furthermore, the proximal groove (4) of the male coupling means (2) has a proximal wall inclined downwards and towards the outside of the panel (1) at an angle (β) with respect to the vertical plane of said panel ( 1). Said angle (β) is between 1° and 45° and, preferably, between 5° and 15°. In this particular embodiment, the angle (α) is substantially equal to the angle (β). It is obvious that the angle (α) may be different from the angle (β) without departing from the scope of the invention.
Par ailleurs, la languette distale (5) des moyens d'accouplement mâles (2) présente une paroi distale comportant, au moins, un ergot (11) apte à coopérer avec une encoche (12) pratiquée sur une paroi proximale que présente la rainure proximale (6) pour former une butée d'arrêt, évitant un déplacement vertical d'un panneau (1) par rapport au panneau adjacent.Furthermore, the distal tongue (5) of the male coupling means (2) has a distal wall comprising at least one lug (11) capable of cooperating with a notch (12) made on a proximal wall that the groove has. proximal (6) to form a stopper, preventing a vertical displacement of a panel (1) relative to the adjacent panel.
Selon l'invention, et par exemple en référence à la
Selon la forme d'exécution illustrée aux

Dans cette forme d'exécution, la paroi distale de la languette flexible déformable (7) comporte également une partie supérieure inclinée suivant un angle compris entre 1° et 20° par rapport à la verticale et une partie inférieure également inclinée suivant un angle compris entre 1° et 20° par rapport à la verticale. Les parties supérieure et inférieure s'étendent parallèlement de part et d'autre d'une encoche (15). La paroi proximale de la rainure proximale (4) comporte également deux parties, une partie supérieure inclinée suivant un angle compris entre 1° et 20° par rapport à la verticale, et une partie inférieure inclinée suivant un angle compris entre 1° et 20° par rapport à la verticale. Les parties supérieure et inférieure s'étendent parallèlement de part et d'autre d'un épaulement formant un ergot (16) apte à coopérer avec l'encoche (15), afin d'améliorer le clippage.In this embodiment, the distal wall of the flexible deformable tongue (7) also comprises an upper part inclined at an angle of between 1° and 20° relative to the vertical and a lower part also inclined at an angle of between 1° and 20° from the vertical. The upper and lower parts extend parallel on either side of a notch (15). The proximal wall of the proximal groove (4) also has two parts, an upper part inclined at an angle between 1° and 20° relative to the vertical, and a lower part inclined at an angle between 1° and 20° relative to the vertical. The upper and lower parts extend parallel on either side of a shoulder forming a lug (16) capable of cooperating with the notch (15), in order to improve clipping.
On notera que l'effort de clippage des panneaux de sol suivant l'invention est légèrement inférieur à l'effort de clippage des panneaux de l'art antérieur lors des premiers millimètres d'engagement des parties mâle et femelle, et que l'effort de déclippage est nettement supérieur à celui des panneaux de l'art antérieur.It will be noted that the clipping force of the floor panels according to the invention is slightly lower than the clipping force of the panels of the prior art during the first millimeters of engagement of the male and female parts, and that the force unclipping is significantly greater than that of the panels of the prior art.
Par ailleurs, on observera que l'orientation suivant un angle compris entre 1° et 45°, et de préférence entre 5° et 15° par rapport à la verticale des parois proximales des languettes (5, 7) des moyens d'accouplement mâles (2) et femelle (3) procure une ouverture des parties mâle (2) et femelle (3) lors du clippage de sorte que l'ergot (11) ne frotte pas sur la paroi proximale de la rainure proximale (6) préservant ainsi l'ergot (11) et réduisant les efforts de clippage. Par ailleurs, cette orientation suivant un angle compris entre 1° et 45°, et de préférence entre 5° et 15° par rapport à la verticale des parois proximales des languettes (5, 7) des moyens d'accouplement mâles (2) et femelle (3) permet de transférer l'effort de cisaillement de l'ergot en compression/torsion dans l'ensemble des profils des parties mâle (2) et femelle (3) augmentant les efforts de déclippage.Furthermore, it will be observed that the orientation at an angle of between 1° and 45°, and preferably between 5° and 15° relative to the vertical of the proximal walls of the tongues (5, 7) of the male coupling means (2) and female (3) provides an opening of the male (2) and female (3) parts during clipping so that the lug (11) does not rub on the proximal wall of the proximal groove (6) thus preserving the lug (11) and reducing the clipping forces. Furthermore, this orientation at an angle of between 1° and 45°, and preferably between 5° and 15° relative to the vertical of the proximal walls of the tongues (5, 7) of the male coupling means (2) and female (3) makes it possible to transfer the shearing force of the lug in compression/torsion in all the profiles of the male (2) and female (3) parts increasing the unclipping forces.
D'une manière avantageuse, la languette distale flexible déformable (5) et la rainure proximale (4) des moyens d'accouplement mâles (2), et la languette flexible déformable (7) et la rainure proximale (6) des moyens d'accouplement femelles (3) sont inclinées vers l'extérieur du panneau (1). En d'autres termes, les languettes distales flexibles déformables (5, 7) comprennent des parois distales sensiblement parallèles à leur parois proximales et sont notamment inclinées respectivement selon un angle (β, α) par rapport à un plan vertical vers l'extérieur du panneau. De la même manière, les rainures proximales (4, 6) comprennent des parois proximales sensiblement parallèles aux parois proximales respectivement des languettes flexibles déformables (5, 7).Advantageously, the deformable flexible distal tongue (5) and the proximal groove (4) of the male coupling means (2), and the deformable flexible tongue (7) and the proximal groove (6) of the female couplings (3) are inclined towards the outside of the panel (1). In other words, the deformable flexible distal tongues (5, 7) comprise distal walls substantially parallel to their proximal walls and are in particular inclined respectively at an angle (β, α) relative to a vertical plane towards the outside of the sign. Similarly, the proximal grooves (4, 6) comprise proximal walls substantially parallel to the proximal walls respectively deformable flexible tongues (5, 7).
De cette manière, les inclinaisons favorisent la déformation de la languette distale flexible déformable (5) des moyens d'accouplement mâles (2) et de la languette flexible déformable (7) des moyens d'accouplement femelles (3) limitant, lors du clippage vertical, les frottements de l'ergot (11) des moyens d'accouplement mâles (2) sur la paroi proximale de la rainure proximale (6) des moyens d'accouplement femelles (3) ainsi que les frottements de l'ergot (16) des moyens d'accouplement mâles (2) sur la paroi distale de la languette (7) des moyens d'accouplement femelles (3) permettant ainsi d'avoir des ergots mieux dimensionnés, de préserver lesdits ergots du frottement, et donc de réduire les efforts de clippage, tel qu'illustré à la
De plus, lesdites inclinaisons favorisent, lors du déclippage, le transfert des efforts de cisaillement perçus par les ergots en efforts de torsion/compression dans l'ensemble des profils des parties mâle (2) et femelle (3), augmentant ainsi les efforts de déclippage, tel qu'illustré à la
La variante d'exécution, en référence aux
De la même façon que pour la forme de réalisation illustrée
De même, comme déjà indiqué, la paroi inférieure de la languette flexible déformable (7) comporte une partie chanfreinée (13) qui procure une réduction de l'effort de clippage de sorte qu'il est plus aisé d'assembler deux panneaux adjacents.Similarly, as already indicated, the lower wall of the deformable flexible tongue (7) comprises a chamfered part (13) which provides a reduction in the clipping force so that it is easier to assemble two adjacent panels.
La paroi distale de la languette flexible déformable (7) comporte deux parties, une partie supérieure inclinée suivant un angle compris entre 1° et 20° par rapport à la verticale et une partie inférieure également inclinée suivant un angle compris entre 1° et 20° par rapport à la verticale. Les parties supérieure et inférieure s'étendant parallèlement de part et d'autre d'une encoche (15). La paroi proximale de la rainure proximale (4) comporte également deux parties, une partie supérieure inclinée suivant un angle compris entre 1° et 20° par rapport à la verticale et une partie inférieure supérieure inclinée suivant un angle compris entre 1° et 20° par rapport à la verticale. Lesdites parties supérieure et inférieure s'étendent parallèlement de part et d'autre d'un épaulement formant un ergot (16) apte à coopérer avec l'encoche (15), afin d'améliorer le clippage.The distal wall of the deformable flexible tongue (7) comprises two parts, an upper part inclined at an angle of between 1° and 20° relative to the vertical and a lower part also inclined at an angle of between 1° and 20° relative to the vertical. The upper and lower parts extending parallel on either side of a notch (15). The proximal wall of the proximal groove (4) also has two parts, an upper part inclined at an angle between 1° and 20° relative to the vertical and an upper lower part inclined at an angle between 1° and 20° relative to the vertical. Said upper parts and lower extend parallel on either side of a shoulder forming a lug (16) capable of cooperating with the notch (15), in order to improve clipping.
Enfin, il est bien évident que les exemples que l'on vient de donner ne sont que des illustrations particulières et en aucun cas limitatifs quant au domaine d'application de l'invention.Finally, it is quite obvious that the examples which have just been given are only specific illustrations and in no way limiting as to the field of application of the invention.
En effet, par exemple et en référence aux
Les avantages ressortent bien de la description, et particulièrement, on souligne et on rappelle que :
- le clippage a une cinématique verticale, mais le fait que les parois proximales des languettes flexibles déformables soient orientées permet de limiter les efforts de clippage et de favoriser le transfert d'effort pour l'action de déclippage.
- l'orientation fait que l'on ouvre au clippage de sorte que l'ergot qui présente la languette ne frotte pas au moment de la descente, préservant ledit ergot et réduisant les efforts de clippage,
- la partie chanfreinée inférieure sur le profil inférieur limite les efforts de clippage et permet de mieux dimensionner l'ergot,
- la partie chanfreinée sur le profil supérieur permet de descendre plus bas lors du clippage et par conséquent, de favoriser la viabilité du clippage.
- the clipping has a vertical kinematics, but the fact that the proximal walls of the deformable flexible tongues are oriented makes it possible to limit the clipping forces and to promote the transfer of force for the unclipping action.
- the orientation means that the clipping is opened so that the lug which presents the tab does not rub during the descent, preserving the said lug and reducing the clipping forces,
- the lower chamfered part on the lower profile limits the clipping forces and allows better sizing of the lug,
- the chamfered part on the upper profile makes it possible to descend lower during clipping and therefore to promote the viability of clipping.
Il ressort des caractéristiques de l'invention les effets techniques et résultats suivants :
Lorsque l'on applique un effort vertical afin d'assembler deux panneaux (1) entre eux, la languette distale flexible déformable (5) des moyens d'accouplement mâles (2) arrive au contact de la languette flexible déformable (7) des moyens d'accouplement femelles (3), ce contact provoque la déformation de la languette distale flexible déformable (5) des moyens d'accouplement mâles (2) ainsi que la déformation de la languette flexible déformable (7) des moyens d'accouplement femelles (3), cette déformation permet l'introduction de la languette distale flexible déformable (5) des moyens d'accouplement mâles (2) dans la rainure proximale (6) des moyens d'accouplement femelles (3) ainsi que l'introduction de la languette flexible déformable (7) des moyens d'accouplement femelles (3) dans la rainure proximale (4) des moyens d'accouplement mâles (2).The following technical effects and results emerge from the characteristics of the invention:
When a vertical force is applied in order to assemble two panels (1) together, the deformable flexible distal tongue (5) of the male coupling means (2) comes into contact with the deformable flexible tongue (7) of the coupling means (3), this contact causes deformation of the deformable flexible distal tongue (5) of the male coupling means (2) as well as the deformation of the deformable flexible tongue (7) of the female coupling means (3), this deformation allows the introduction of the deformable flexible distal tongue (5) of the male coupling means (2) into the proximal groove (6) of the female coupling (3) as well as the introduction of the deformable flexible tongue (7) of the female coupling means (3) into the proximal groove (4) of the male coupling means (2).
Lorsque l'on n'applique plus d'effort vertical, la languette distale flexible déformable (5) des moyens d'accouplement mâles (2) reprend sa forme initiale permettant ainsi à l'ergot (11) des moyens d'accouplement mâles (2) de coopérer avec l'encoche (12) des moyens d'accouplement femelles (3), et la languette flexible déformable (7) des moyens d'accouplement femelles (3) reprend sa forme initiale permettant ainsi à l'ergot (16) des moyens d'accouplement mâles (2) de coopérer avec l'encoche (15) des moyens d'accouplement femelles (3).When no more vertical force is applied, the deformable flexible distal tongue (5) of the male coupling means (2) resumes its initial shape, thus allowing the lug (11) of the male coupling means ( 2) to cooperate with the notch (12) of the female coupling means (3), and the deformable flexible tongue (7) of the female coupling means (3) resumes its initial shape, thus allowing the lug (16 ) male coupling means (2) to cooperate with the notch (15) of the female coupling means (3).
Lorsque l'on applique un effort visant à désassembler deux panneaux (1) la coopération de l'ergot (11) des moyens d'accouplement mâles (2) avec l'encoche (12) des moyens d'accouplement femelles (3) ainsi que de l'ergot (16) des moyens d'accouplement mâles (2) avec l'encoche (15) des moyens d'accouplement femelles (3) provoque un effort de cisaillement entre l'ergot (11) des moyens d'accouplement mâles (2) et l'encoche (12) des moyens d'accouplement femelles (3) ainsi qu'entre l'ergot (16) des moyens d'accouplement mâles (2) et l'encoche (15) des moyens d'accouplement femelles (3). L'effort de cisaillement entre l'ergot (11) des moyens d'accouplement mâles (2) et l'encoche (12) des moyens d'accouplement femelles (3) provoque une déformation de la languette distale flexible déformable (5) des moyens d'accouplement mâles (2), l'effort de cisaillement entre l'ergot (16) des moyens d'accouplement mâles (2) et l'encoche (15) des moyens d'accouplement femelles (3) provoque une déformation de la languette flexible déformable (7) des moyens d'accouplement femelles (3). La déformation conjointe de la languette distale flexible déformable (5) des moyens d'accouplement mâles (2) et de la languette flexible déformable (7) des moyens d'accouplement femelles (3) provoque un contact prépondérant/coincement entre la languette distale flexible déformable (5) des moyens d'accouplement mâles (2) et de la languette flexible déformable (7) des moyens d'accouplement femelles (3). Ce contact prépondérant permet de transférer l'effort de cisaillement entre l'ergot (11) des moyens d'accouplement mâles (2) et l'encoche (12) des moyens d'accouplement femelles (3) ainsi que l'effort de cisaillement entre l'ergot (16) des moyens d'accouplement mâles (2) et l'encoche (15) des moyens d'accouplement femelles (3) en effort de torsion/compression dans l'ensemble des profils des parties mâle (2) et femelle (3) augmentant ainsi les efforts de déclippage.When applying a force aimed at disassembling two panels (1) the cooperation of the lug (11) of the male coupling means (2) with the notch (12) of the female coupling means (3) as well that the lug (16) of the male coupling means (2) with the notch (15) of the female coupling means (3) causes a shear force between the lug (11) of the coupling means males (2) and the notch (12) of the female coupling means (3) as well as between the lug (16) of the male coupling means (2) and the notch (15) of the mating females (3). The shearing force between the lug (11) of the male coupling means (2) and the notch (12) of the female coupling means (3) causes deformation of the deformable flexible distal tongue (5) of the male coupling means (2), the shearing force between the lug (16) of the male coupling means (2) and the notch (15) of the female coupling means (3) causes a deformation of the deformable flexible tongue (7) of the female coupling means (3). The joint deformation of the deformable flexible distal tongue (5) of the male coupling means (2) and of the deformable flexible tongue (7) of the female coupling means (3) causes a predominant contact/wedging between the flexible distal tongue deformable (5) of the male coupling means (2) and of the deformable flexible tongue (7) of the female coupling means (3). This contact preponderant makes it possible to transfer the shearing force between the lug (11) of the male coupling means (2) and the notch (12) of the female coupling means (3) as well as the shearing force between the lug (16) of the male coupling means (2) and the notch (15) of the female coupling means (3) under torsion/compression force in all the profiles of the male (2) and female parts (3) thus increasing the unclipping forces.
