Definitions

• the present invention relates to the field of free-standing floor coverings, and relates more particularly to a panel, preferably made of polyvinyl chloride, having a blade or slab shape for producing such a covering, the assembly of which takes place according to a kinematics inclined on a first edge, and vertical on a second adjacent edge.
• this type of panel includes two pairs of opposite sides defining:
• This type of panel is illustrated for example by document EP 3 105 392, and document US 2013/0309441.
• documents both describe a panel having first and second complementary male / female coupling means on opposite pairs of sides to assemble similar panels to form a floor covering.
• the coupling means of the short sides have complementary means to oppose the vertical disassembly, and external walls inclined with respect to a vertical plane and oriented towards the inside of the panel.
• the assembly is carried out by tilting the panels along a long side and locking them vertically on a small side.
• the means described in document EP 3 105 392, for opposing the vertical disassembly of two panels, in particular in the form of bulges and cavities, do not have optimal effectiveness.
• document US 2013/0309441 describes a female tongue having a chamfered part at the level of the underside of the panel, with a view to facilitating the assembly of two panels, but which does not have optimal efficiency.
• One of the aims of the invention is therefore to remedy the aforementioned drawbacks by proposing a panel for producing a free-standing floor covering, the assembly of which is carried out according to kinematics inclined on an edge, then vertical on an adjacent edge.
• Another object of the invention is to facilitate the assembly of two similar panels, and also to provide a panel having optimal resistance to horizontal and vertical disassembly, as well as satisfactory aesthetics.

Furthermore, the fact that the male stud has an external wall inclined with respect to a vertical plane and towards the outside of the panel promotes vertical assembly during the rotational movement.
• the installer places the panels in abutment: the lower part of the male stud comes to rest against the upper part of the female groove. Consequently, during installation, the installer sees the groove and can therefore easily position the external wall of the male stud in line with the groove to start assembly. Then, advantageously, during the pivoting, the two panels approach each other. The machining constraints to have perfect contact on the surface of the panels are then easier to respect.
• the presence of the lug and notch also makes it possible to optimize the resistance to vertical disassembly, since the projecting angles of the lug and notch allow a more effective locking than the bulges and cavities of the prior art.
• the female external stud has a chamfered part at the lower face of the panel and forming an angle between 2 ° and 20 ° relative to the lower face of the panel.
• the chamfered part allows the lowering of the female post during the assembly of two adjacent panels to come, by deformation, into contact with the ground and thus provide a reduction in the assembly effort.
