Definitions
- TITLE Parquet strip including a removable interlocking assembly system
- the present invention relates to a floorboard comprising a removable interlocking assembly system.
- parquet There are different types of parquet known in the industry such as engineered parquet and solid parquet.
- Solid parquet has many advantages over other types of existing parquet.
- Solid parquet for example, has superior aesthetic properties and is also more resistant to moisture. It also has a longer lifespan.
- Each type of parquet corresponds to one or more laying techniques adapted according to the type of parquet and the thickness of the parquet strips.
- laying techniques we can mention a nailed laying in which the parquet strips are nailed to joists resting on a continuous or discontinuous support, a glued laying in which the parquet strips are glued on a continuous support, and finally a floating installation in which the floorboards are placed on a continuous support with no means of connection other than the contact established by the weight of a floorboard.
- only laminated parquet strips are compatible with floating installation.
- nailed or glued installation For the installation of solid parquet, you can use nailed or glued installation. The parquet strips are then either nailed to the joists or glued with parquet glue. The nailed installation can be difficult to implement since it requires the installation of joists for example as well as suitable equipment.
- the glued installation although simpler to implement, is not reversible and results, in the vast majority of cases, in the destruction of the parquet when it must be removed when a building reaches the end of its life, for example. If they are thus implemented, the floors are not reusable. The carbon stored in the floorboards during the life of the floor is therefore released at the end of the life of the floor. It will then be necessary to mobilize once again the forest resource to manufacture new floorboards.
- Parquet assembly solutions that are easy to implement and reversible have been devised in order to obtain removable and reusable parquet strips in order to reduce the ecological impact and limit manufacturing costs.
- Document EP2843154B1 describes, for example, a solution for assembling reversible floorboards comprising an active locking system comprising a movable locking element.
- the system described in the document EP2843154B1 requires for the parquet assembly an additional locking element and consequently a higher manufacturing cost.
- the technical problem at the basis of the invention then consists in providing an assembly of removable and reusable floorboards which is of simple structure, economical and with low ecological impact.
- the subject of the present invention is a parquet strip comprising a first main surface intended to form an apparent surface and a second main surface opposite the first main surface and intended to rest on a support, a first front edge and a second front edge, the first front edge being arranged to cooperate with a second front edge of another floorboard, the first front edge comprising a first front wall and a tab extending from the first front wall towards a distal end opposite the first front wall, the tongue comprising a first convex bearing surface arranged on a first side of the tongue, a second bearing surface arranged on a second side of the tongue opposite the first side, the second bearing surface being extended in the direction of the distal end of the tongue by a rounding, the second front edge comprising a second wall fr front having a groove defining an opening and an interior wall extending from a first end of the opening, the interior wall comprising a first concave bearing surface disposed on a first side of the opening, a surface bottom and a second support surface arranged on
- the floorboard may additionally have one or more of the following characteristics, taken alone or in combination.
- the ratio between the length of the tongue and the depth of the groove can for example be between 0.6 and 0.99.
- the ratio of the distance between the first major surface and a first tongue end disposed on the first tongue bearing surface at the intersection between the first tongue bearing surface and the first front wall to the distance between the first main surface and a second tongue end arranged on the second bearing surface of the tongue at the intersection between the second bearing surface of the tongue and the first front wall can be between 0.2 and 0, 75.
- the floorboard is made of solid wood.
- the floorboard may comprise a wear layer extending from the first main surface in a direction orthogonal to a plane of the floorboard 1 and representing a fraction of a thickness of the floorboard parquet by at least 25%, and preferably by more than 35% or even by more than 40%, the thickness of the parquet strip being considered between the first main surface and the second main surface, the tongue and the groove being positioned relative to the thickness of the floorboard in a bottom layer of the floorboard disposed below the wear layer.
- the parquet strip comprises a chamfer arranged on the other side of the rounding with respect to the second bearing surface of the tongue.
- the chamfer can have an angle of inclination with respect to an insertion axis between 10 degrees and 45 degrees.
- the value of the angle of inclination of between 10 degrees and 45 degrees facilitates the fitting of the tongue into the groove.
- the second bearing surface of the tab can be configured to be substantially planar.
- the parquet strip further comprises a first lateral edge and a second lateral edge of the parquet strip positioned opposite the first lateral edge, the first lateral edge comprising a first flange extending along a plane of the floorboard and an anchoring abutment extending from the flange in a direction transverse to a plane of the floorboard, the second lateral edge comprising a second flange extending in the plane of the floorboard and an anchoring cavity provided in the second edge, said anchoring cavity being of complementary shape to the anchoring abutment and intended to receive the anchoring abutment of a neighboring floorboard.
- the first rim comprises a surface arranged in the extension of the first main surface of the parquet strip
- the second flange comprises a surface arranged in the extension of the second main surface of the floorboard.
- the anchoring abutment and the anchoring cavity have a triangular shape.
- the first rim extends from the first main surface, the thickness of the first rim is greater than the thickness of the wear layer, and the anchoring abutment is placed in the lower layer , or according to a second possibility, the second flange extends from the first main surface, the thickness of the second flange is greater than the thickness of the wear layer, and the anchoring cavity is arranged in the bottom layer.
- the second flange extends from the second main surface and is included in the lower layer.
- the first rim extends from the second main surface and is included in the lower layer.

- the first support surface of the tongue is arranged to slide on the first support surface of the groove of a neighboring parquet strip between: an initial sliding position in which the support point belongs to a plan of the opening; and a final sliding position in which the fulcrum is in contact with the abutment surface.
- the sliding path is curved and defined by the first support surface.
- the second bearing surface of the tongue can be arranged to bear against the second bearing surface of the groove.
- the sliding movement of the tongue in the groove prevents the tongue from breaking when the latter is subjected to a high distributed load, for example of a value substantially equal to 500 daN/m2 and to a high concentrated load, for example of a value substantially equal to 700daN.
- the sliding movement of the tongue in the groove is reversible and results in that two floorboards can be dismantled and reusable thus constituting a non-fixed assembly after interlocking of the two floorboards.

- the invention relates to a parquet strip 1 presented in FIG. 1 and comprising a first main surface 5 intended to form an apparent surface exposed to the footsteps of a user of the parquet floor, for example, and a second main surface 5' opposite the first main surface 5 and intended to rest on a support such as the ground, for example a screed or a slab, of a dwelling or a tertiary building for example.
- the parquet strip 1 described can be made of solid wood.
- the parquet strip 1 described can be an engineered parquet strip.
- the floorboard 1 may comprise a wear layer 5a shown in Figure 5 and extending from the first main surface 5 in a direction orthogonal to a plane of the floorboard 1 and representing a fraction of a thickness of the parquet strip 1 of at least 25%, and preferably more than 35% or even more than 40%, the thickness of the parquet strip 1 being considered between the first main surface 5 and the second main surface 5', the tongue 6 and the groove 7 being positioned relative to the thickness of the parquet strip 1 in a lower layer 5b of the parquet strip 1 arranged below the wear layer 5a.
- the wear layer 5a can be renovated, in other words, it is possible to sand the parquet so as to find a smooth surface by removing material in the thickness of the wear layer 5a.
- the floorboard also comprises a first front edge 2 which can also be called the male part and a second front edge 3 which can also be called the female part, the first front edge 2 being arranged to cooperate with a second front edge 3 of another board flooring, in other words to make a male-female assembly by interlocking a male part of a floorboard with a female part of another floorboard, the fitting being advantageously reversible.
- solid wood being a material whose dimensions can vary according to a hygrometry and a temperature of an environment in which it is located
- the parquet strip 1 described makes it possible to take account of the variations of solid wood. depending on the hygrometry and temperature of an environment in which it is located.
- the first front edge 2 comprises a first front wall 28, 21 and a tab 6 extending from the first front wall 28, 21 towards a distal end opposite the first front wall 28, 21.
- Figure 2 shows a sectional view of a first embodiment of the first front edge 2 in which the tongue 6 has a curved shape and comprises a first smooth and convex bearing surface 27 disposed on a first side of the tongue 6, a second bearing surface 22 arranged on a second side of the tab opposite the first side, the second bearing surface 22 being able to be configured to be substantially planar and being able to be extended in the direction of the distal end 26 of the tongue by a rounding 23.
- the parquet strip can also comprise a chamfer 24 placed on the other side of the rounding 23 with respect to the second bearing surface 22 of the tongue 6.
- the first bearing surface 27 may comprise a first portion 27a, a second portion 27b and a third portion 27c arranged on the bearing surface 27 so that an obtuse intersection angle is made between the first portion 27a and the second portion 27b, and an obtuse intersection angle is made between the second portion 27b and the third portion 27c.
- intersection angle is meant the angle measured starting from the first portion 27a and rotating clockwise to reach the second portion 27b, and starting from the second portion 27b and rotating clockwise to reach the third portion 27c.
- the chamfer 24 has an angle of inclination with respect to an insertion axis B (FIG. 2) comprised between 10 degrees and 45 degrees.
- the chamfer 24 can be replaced by a curved edge connecting the rounding 23 to one end of the tongue 25.
- a first embodiment of the second front edge 3 shown in Figure 3 comprises a second front wall 11, 16 having a groove 7 defining an opening and an inner wall extending from a first end of the opening 18.

- intersection angle is meant the angle measured starting from the first portion 15a and rotating clockwise to reach the second portion 15b, and starting from the second portion 15b and turning clockwise to reach the third portion 15c.
- the parquet strip described can be remarkable in that the width W of the opening of the groove 7 which is visible in FIG. 3 is equal to the distance between the first bearing surface 27 of the tongue 6 and the rounded 23 increased by a functional clearance J1 dimensioned so that the ratio of the distance between the first bearing surface 27 of the tongue 6 and the rounding 23 over the width of the opening W of the groove 7 is substantially between 0.7 and 0.99., and in that the length L of the tongue 6 shown in Figure 2 and considered between the first front wall 28, 21 and the end of the tongue 25 disposed on the tongue 6 at the opposite the first front wall 21, 28 is less than the depth P of the groove considered between the opening of the groove and the bottom surface 13 of the groove 7. This results in that the end of the tongue 25 may not be in contact with the bottom surface 13.
- the ratio between the length L of the tongue 6 and the depth P of the groove 7 can for example be between 0.6 and 0.99.
- the ratio of the distance between the first main surface 5 and a first end X of tongue 6 arranged on the first bearing surface 27 of the tongue 6 at the intersection between the first bearing surface 27 of the tongue 6 and the first front wall 28,21 over the distance between the first main surface 5 and a second end Y of tongue 6 arranged on the second bearing surface 22 of the tongue 6 at the intersection between the second bearing surface 22 of the tab 6 and the first front wall 28.21 can be between 0.2 and 0.75.
- the parquet strip 1 may further comprise a first lateral edge 4 which comprises a first rim extending along a plane of the parquet strip and an anchoring abutment 9 extending from the rim in a direction transverse to a plan of the floorboard as shown in Figure 4.
- the first flange may comprise a surface arranged in the extension of the first main surface 5 of the floorboard 1 also visible in Figures 4 and 9.
- the parquet strip 1 can also comprise a second lateral edge 8 presented in FIGS. 4, 9 and 11 and disposed opposite the first lateral edge 4, the second lateral edge 8 comprising a second flange extending in the plane of the blade.
- the second rim can comprise a surface arranged in the extension of the second main surface 5' of the parquet strip 1 .
- An anchoring cavity 10 can be arranged in the second rim, said anchoring cavity 10 being of complementary shape to the anchoring stop 9 and intended to receive the anchoring stop 9 of a neighboring floorboard.
- the first rim extends from the first main surface 5, the thickness of the first rim is greater than the thickness of the wear layer 5a, and the anchoring abutment 9 is placed in the lower layer 5b.
- the second rim extends from the second main surface 5' and is included in the lower layer 5b.
- the second flange can, according to a second possibility, extend from the first main surface 5, the thickness of the second flange is greater than the thickness of the wear layer 5a, and the anchoring cavity 10 is arranged in the lower layer 5b.
- the first rim extends from the second main surface 5' and is included in the lower layer 5b.
- the anchoring abutment 9 and the anchoring cavity 10 have a triangular shape like that of FIGS. 4, 9 and 11 for example.
- the tongue 6 of the floorboard 1 may possibly undergo a translational movement by sliding within the groove 7 of a neighboring floorboard .
- the invention provides for the anchoring abutment 9 of the parquet strip 1 to be inserted into the anchoring cavity 10 of a neighboring parquet strip as an additional fixing means, so as to block a such translational movement.
- a clearance J2 can be arranged between the first side edge 4 of the floorboard 1a and the second side edge 8 of the neighboring floorboard 1b .
- the tongue 6 may have a bearing point 26 arranged in the direction of the distal end of the tongue with respect to the first bearing surface of the tongue.
- the inner wall of the groove has an abutment surface 14 arranged in the extension of the first bearing surface 15 of the groove.
- the fulcrum 26 can be configured to come into abutment on the abutment surface 14 of a neighboring floorboard when the tongue 6 is introduced into the groove 7.
- the first bearing surface 27 of the tongue is arranged to slide on the first bearing surface 15 of the groove of an adjacent parquet strip according to a sliding path which can be curved and defined by the first bearing surface 15 between: an initial sliding position in which the fulcrum 26 belongs to a plane of the opening; and a final sliding position in which the fulcrum 26 is in contact with the abutment surface 14.
- the second bearing surface 22 of the tongue 6 of figure 2 can be arranged to bear against the second bearing surface 12 of the groove 7 of figure 3.
- the first front wall 28, 21 and the second front wall 11, 16 may not be in permanent contact during the interlocking of the parquet strip 1 with a neighboring parquet strip due to the presence of the functional clearance J1 and because the length L of the tongue 6 is less than the depth P of the groove 7.
- the sliding movement of the tongue 6 in the groove 7 makes it possible to avoid the breakage of the tongue 6 when the latter is subjected to a high distributed load, for example of a value substantially equal to 500 daN/m2 and at a high concentrated load, for example of a value substantially equal to 700 daN.
- the tongue 6 of a neighboring floorboard can slide in the groove 7 of the floorboard 1 and form, advantageously, a stable floor covering work which does not require the fixing of the floorboards by an additional fixing means such as parquet glue for example.
- the value of the angle of inclination of the chamfer 24 with respect to the insertion axis B of between 10 degrees and 45 degrees facilitates the fitting of the tongue 6 into the groove 7.
- the sliding movement of tongue 6 in groove 7 is reversible and results in two floorboards being removable and reusable, thus constituting a non-fixed assembly after the two floorboards have been fitted together.
- two floorboards can separate to cooperate again on another support.
- two neighboring floorboards can be assembled so as to support natural deformations of the wood depending on the humidity of the ambient air, such as a variation in the width of the floorboard of 0.15% for a humidity variation of 1%, while remaining united and therefore allowing installation of the parquet without parquet glue or other assembly component. Failure to use parquet glue or any assembly component results in that the floorboards are easily removable and therefore in that the laying of the floor becomes easy, reversible and with a low environmental footprint.
