Description

 FINISHING ACCESSORY SUITABLE FOR FORMING A CONNECTION

BETWEEN TWO SURFACES Technical Area

 The present invention relates to the field of interior decoration and relates to a new finishing accessory adapted to form a connection between two surfaces.

 Prior art

 In the particular context of laying flooring, floating or gluing, wood or the like, or laying carpet, carpet or tile flooring, it is customary to use different types of finishing accessory made of wood or the like, of plastics or metal, which may or may not be covered with a decorative film, in order to make aesthetic fittings, for example between two adjacent and disjoint floor coverings, or between a floor covering and a wall.

 It has been proposed to date finishing accessories that are modular and multifunction. For example, in international patent applications WO 2006/074824 and WO 2006/079468, multifunction finishing accessories for floor covering are proposed, comprising different modules which are covered by a decorative film, and which are separable, after cutting of the decorative film, so that the finishing accessory is configurable for use in different finishing functions, and in particular a junction function between two floor coverings, or a stop function or a level catch function between a floor covering and floor or other floor covering of different thickness.

The function of junction between two floor coverings is usually carried out by means of a linear profile having in cross section mainly a T shape, with a central foot enabling the junction profile between the two facing surfaces to be fixed, and two wings. of cover which extend laterally on either side of the central foot, which are adapted to each cover an underlying part of a coating. When the floor covering is thin, the T-shaped function profile can also be used as a tie bar between said coating and a portion of bare floor without coating.

 With multifunction finishing accessories, of the type of those described for example in international patent applications WO 2006/074824 and WO 2006/079468, the stop function between a floor covering and a wall is obtained by means of the profile of aforementioned T-shaped junction and a complementary linear portion underlying one of the lateral flanges of the T-junction profile.

 There are also other types of finishing accessories which are adapted to form a connection between two surfaces, among which may be mentioned by way of non-limiting and non-exhaustive examples: the baseboards which are adapted to make a connection aesthetic between a wall and a floor covering or the floor; finishing moldings which are adapted to provide an aesthetic connection between a ceiling and a wall; the picture rails; the nosings that are adapted to achieve an aesthetic connection between the top of the step and the riser.

Whatever the type of finishing accessory, the apparent face of the accessory must be aesthetically adapted to the two surfaces that are intended to be connected by means of said finishing accessory. For this purpose this apparent face is generally printed with a decorative pattern or is covered with a decorative film (plastic film, wood veneer, melamine ...) which is permanently bonded to the finishing accessory, which limits possibilities of using the finishing accessory. In addition, this requires manufacturers and sellers of finishing accessories to hold large quantities of finishing accessories with different decorative films or patterns in stock, which complicates and increases inventory management costs. Objective of the invention

 The present invention aims to provide a new finishing accessory that overcomes the above drawbacks arising in the prior art from the implementation of a single coating or decorative pattern for each finishing accessory.

 Summary of the invention

 The invention thus has as its first object a finishing accessory adapted to form a connection between two surfaces and comprising a linear base piece and a linear facing piece; the linear base piece has an upper face having a curved profile; said linear base and facing parts comprise assembly means for assembling them mechanically together, so that the linear facing piece completely covers and matches the upper face of the linear base piece and forms the visible face of the finishing accessory; the linear facing piece also has a cross-sectional profile which can be modified so that it can, if necessary, completely cover and marry the upper face of the linear basic part of the finishing accessory or the upper face of at least another linear base piece having in cross section a different profile with an upper face having a different curved profile.

 detailed description

 FIG. 1 shows an example of a multifunction finishing assembly of the invention comprising three separate linear basic parts 1A, 1B, 1C and having different profiles in cross-section, that is to say in the transverse plane (X, Z), and a linear piece of flexible facing 2. Each linear base piece 1A, 1B, 1C and the linear piece of facing 2 extend longitudinally in the direction Y on substantially the same length L. In the accompanying figures, for the sake of simplification of the drawings, this length L is small , it being specified however that this length L will in practice be greater than that illustrated in the appended figures.

 The linear base part 1A is constituted by a rigid profile having in cross section a T-shaped profile with a central foot 10 extended symmetrically on either side in the upper part by two side wings 1 1 thin and identical.

The linear base part 1 B is constituted by a rigid profile having in cross section an asymmetric profile with a central foot 10 extended on both sides in the upper part by a thin side wing 12 and a side wing 13 of greater thickness.

 The linear base piece 1C consists of a rigid section having in cross section an asymmetrical profile with a central foot 10 extended on either side in the upper part by a thin side wing 12 and a lateral flange 14 of greater thickness and having an upper surface forming substantially a right angle.

 The upper face 15 of each linear base part 1A, 1B and 1C has a total area which is identical for all the basic linear parts 1A, 1B and 1C but whose curved profile is different for all the linear parts. basic 1A, 1B and 1C.

 The basic linear parts 1A, 1B and 1C can indifferently according to the invention be made in any type of material, and in particular wood, metal, and for example aluminum, or plastic and for example PVC or similar, and can be manufactured by any known method, in particular by extrusion, molding or machining.

 The linear facing piece 2 is deformable so as to completely cover and marry the curved shape of the upper face 15 of each linear base piece 1A, 1B or 1C. Preferably, the linear facing piece 2 is a piece flexible so that after deformation, and in the absence of stress, it returns to its initial shape at rest in Figure 1. The linear facing piece 2 can also be a flexible piece which once deformed and in the absence of stress retains its shape.

 In Figure 1, the linear facing piece 2 is not deformed and thus has a profile adapted for its assembly with the linear base part 1A.

 In Figure 2, the linear facing piece 2 is deformed so as to have a profile adapted for its assembly with the linear base part 1 B.

In FIG. 3, the linear facing piece 2 is deformed in so to present a profile adapted for its assembly with the basic linear part 1 C.

 In the particular example illustrated in FIGS. 1, 2 and 3, this linear facing piece 2 is a flexible or flexible plate of small thickness e, the two longitudinal edges of which are folded inwards so as to form a longitudinal slideway. assembly 21. Each linear base piece 1A, 1B, 1C has longitudinal edges 16 whose geometry is adapted so as to be inserted longitudinally into the longitudinal assembly slide 21 of the linear facing piece 2.

 The linear facing piece 2 can be made of any material giving it the required deformability and, if necessary, the required flexibility or flexibility. The linear facing piece 2 is for example plastic, and in particular PVC, or elastomer, especially rubber. Its upper face 22 may optionally be printed with a decorative pattern or be covered with a monolayer or multilayer decorative film, for example of the PVC type, melamine or wood veneer. The lower face 23 and / or the upper face 22 of the linear facing piece 2 may be self-adhesive.

 With reference to FIG. 13, the linear facing pieces 2 may, for example, but not necessarily, be manufactured in series by industrial cutting of a set of juxtaposed facing pieces 2 which has been previously manufactured.

With reference to FIGS. 4 and 5, to assemble the linear facing piece 2 with the linear base piece 1A and to form a first finishing accessory A according to the invention, it suffices to thread the linear facing piece 2, the undistorted state, on the linear base piece 1A by fitting longitudinally (arrow F) the lateral flanges 1 1 of the linear base piece 1A in the longitudinal assembly slide 21 of the facing piece 2, and making longitudinally slide the two parts 2 and 1A relative to each other until the piece of 2 completely covers (Figure 6) the upper face 15 of the linear base part 1A.

 In another variant embodiment, the linear facing piece 2 could have a profile in cross section such that its assembly with the T-shaped linear base piece 1A requires deformation of the linear facing piece 2.

 Referring to Figure 6, the finishing accessory A is fixed on the ground S, between two floor coverings R1 and R2, by means of a U-shaped fastening strip 3 in which the central foot 10 is fitted. of the finishing accessory A. In this configuration, the finishing accessory A (basic linear part 1A / facing piece 2) serves as a connecting bar between the two floorings R1, and R2 having substantially the same thickness .

 With reference to FIGS. 7 and 8, to assemble the linear facing piece 2 with the linear base piece 1 B and to form a second finishing accessory B according to the invention, it suffices to deform the linear facing piece 2 so as to to adapt it to the curved profile of the upper face 15 of the linear base piece 1B, and to thread the linear piece of facing 2, in the deformed state, onto the linear base piece 1B while fitting longitudinally ( arrow F) the lateral flanges 1 1 of the linear base piece 1 B in the longitudinal assembly slide 21 of the facing piece 2, and by longitudinally sliding the two pieces 2 and 1 B relative to each other. other until the facing piece 2 completely covers (FIG. 9) the upper face 15 of the linear base part 1 B.

Referring to Figure 9, the finishing accessory B is fixed on the ground S, in the vicinity of the edge of a floor covering R1, by means of a fastening strip 3 U-shaped in which is fitted the central foot 10 of the finishing accessory B. In this configuration, the finishing accessory B (basic linear part 1 B / facing piece 2) serves as a connecting bar or threshold bar between the floor S and the covering of soil R1. With reference to FIGS. 10 and 11, to assemble the linear facing piece 2 with the linear base piece 1C and to form a third finishing accessory C according to the invention, it suffices to deform the linear facing piece 2 of in order to adapt it to the curved profile of the upper face 15 of the linear base piece 1C, and to thread the linear facing piece 2, in the deformed state, onto the linear base piece 1C while fitting longitudinally (arrow F) the lateral wings 1 1 of the linear base piece 1 B in the longitudinal assembly slide 21 of the facing piece 2, and by longitudinally sliding the two pieces 2 and 1 C relative to each other. the other until the facing part 2 completely covers (Figure 12) the upper face 15 of the linear base part 1 B.

 Referring to Figure 12, the finishing accessory C is fixed on the ground S, in the vicinity of the edge of a floor covering R1, by means of a fastening strip 3 in the form of a U in which is engaged the central foot 10 of the finishing accessory C. In this configuration, the finishing accessory C (basic linear part 1 C / facing piece 2) serves as a stop bar between the floor covering R1 and the floor S .

 Whatever the finishing accessory A, B or C, the linear facing piece 2 forms the visible face of the finishing accessory, that is to say the part of the finishing accessory which is visible once the finishing accessory placed as a connection between two surfaces (R1 and R2) or (R1 and S).

 When the facing piece 2 is flexible, once assembled in the deformed state with the base part 1 B or 1 C, it tends to return to its original shape of Figure 1, which helps to strengthen its attachment to the basic linear part.

The manufacture of the finishing accessory by assembling the linear facing part 2 with a linear base part 1A, 1B, or 1C can be done at the factory. Nevertheless, preferably, the basic linear parts 1A, 1B, 1C and the linear facing pieces 2 are sold separately, and the end user himself makes the finishing accessory on measuring, for example just before proceeding to its installation, having advantageously selected the base part 1A, 1 B or 1 C whose geometry is adapted to the finishing fitting he wishes to achieve, and having advantageously selected the piece of facing 2 which has the desired decor.

 In addition, when the facing piece 2 is removable relative to the base part 1A, 1 B or 1 C, the end user can advantageously change the visual appearance of a finishing accessory already installed, by replacing the piece facing 2 of the finishing accessory by another facing piece 2 having for example another decorative pattern on its upper face.

 FIG. 14 shows another embodiment of a multifunction finishing assembly of the invention comprising a linear facing piece 2 'and three basic linear pieces 1' ', the B' and the C '.

 The basic linear parts 1 Ά, 1 'B and 1' C are different from the basic linear parts 1A, 1B, 1C previously described by the implementation of a longitudinal groove 4, which is made in the upper face. Linear basic parts 1 Ά, 1 Έ and 1 'C, and which extends longitudinally (Y direction) along the entire length of the workpiece. The linear facing piece 2 'differs from the linear facing piece 2 previously described by the implementation of two adjacent longitudinal wings 5, which extend transversely (plane (Y, Z)) from the underside 23 of the piece Linear facing 2, and which extend longitudinally (Y direction) over the entire length of the room.

 The longitudinal groove 4 of each base part 1 Ά, the B, the C is adapted to serve as a housing for the two longitudinal wings 5 of the facing piece 2 ', when the facing piece 2' and the base piece 1 Ά, 1 Έ or 1 'C are assembled together (Figures 15, 16 and 17).

Furthermore, each basic linear part 1 1, 1 'B or 1' C can advantageously be separated at least in two parts along a longitudinal sectional plane P1 passing through the groove 4. In FIG. represented one of the two L-shaped parts of the linear part 1 Ά after cutting. Also, the facing piece 2 'can advantageously be separated into two parts 2'a, 2'b (FIG. 19), for example by a longitudinal cut of the part 2' made by means of a cutting blade between the two wings 5. Each portion 2'a, 2'b is thus adapted to be assembled with the corresponding part of the base piece (Figure 18) to form another type of finishing accessory such as for example that illustrated in FIG. 20.

 In the context of the invention, a linear base piece is not necessarily a one-piece piece, but may be constituted by an assembly of several pieces, hereinafter referred to as modules. For example, FIG. 24 shows an assembly comprising a main module A1 having in cross-section an L-shaped profile and three other complementary modules A2, B2, and C2, each of which can be individually assembled with the main module A1 so as to constitute respectively three basic linear parts 1 "A (Figure 25), 1" B (Figure 26) and 1 "C (Figure 27) In this embodiment, the mechanical assembly of the modules is obtained by means of a connecting key 6 and thanks to the implementation in each module of an assembly groove 7 allowing a tenon-mortise type interlocking of the connecting key 6.

 The end user can thus advantageously manufacture himself his basic linear part 1 "A, 1" B or 1 "C from module A1 and one of the modules A2, B2 or C2, and then make the accessory finishing A, B or C by assembling the linear facing piece 2 '(Figures 28, 29 and 30) .The manufacture of the basic linear part 1 "A, 1" B or 1 "C from the module A1 and of one of the modules A2, B2 or C2 can also be performed in the factory.

FIG. 31 shows another embodiment of a multifunction finishing assembly of the invention comprising a linear facing piece 2 "and two linear base pieces 8A, 8B. The linear base piece 8A has in cross section a profile in π, with a U-shaped portion forming a central foot 10 surmounted by a portion 1 1 in the form of a plate whose upper face 15 'is flat and forms the face upper part of the linear base part 8A. The central leg 10 allows the ground fixing of the base piece 8A by means of a suitable fixing interface 3 '(Figure 34).

 The linear base piece 8B differs from the linear base piece 8A by an upper surface 15 'which is not flat but which is curved.

 The linear facing piece 2 "comprises a longitudinal slideway 21 allowing its assembly with either the linear base piece 8A (FIG. 32) or the linear base piece 8B, in a manner comparable to that previously described for the other variants. When assembled with the linear base piece 8A, the facing piece 2 "is not deformed and forms with the linear base piece 8A a finishing accessory A (FIG. 34) whose apparent face is constituted by the facing piece 2 ". When it is assembled with the linear base piece 8B, the facing piece 2" is deformed, preferably elastically, so as to match the curved profile of the upper face 15 'of the base piece 8 and to form with the linear base piece 8B a finishing accessory B (Figure 35) whose apparent face is constituted by the facing piece 2 ".

More particularly, the linear facing piece 2 "has a longitudinal through hole 24, which allows the insertion by one end of the facing piece 2" of a cutting tool 9 (Figure 37) having two cutting blades 9a, 9b, and which allows the translational guidance of the cutting blades 9a, 9b over the entire length of the facing piece 2 ".The end user can thus proceed to the cutting into two parts of facing piece 2", which allows to modify the profile in cross section of this facing piece 2 '(Figure 36). The cutting can be performed before or after assembly of the facing piece 2 "with the piece of base 8A.

 FIG. 38 shows another variant of a linear base piece 8Ά that can replace the piece 8A, but which is not a single piece and consists of the assembly of three parts M1, M2, M3. With reference to FIG. 39, the positioning of the three parts M1, M2, M3 has been modified so as to constitute another linear base part 8'B which can replace the part 8B.

 FIG. 40 shows another variant embodiment of a multifunction finishing assembly comprising a linear facing piece 2 "'and a linear base piece 1.

 The linear facing piece 2 "'is a rigid one-piece piece of thin thickness and separable by cutting (FIG. 41) in three different ways, so as to form either the linear facing piece 2A of FIG. 42, or the linear piece of FIG. 2B of Figure 45, the linear facing part 2C of Figure 48.

 The linear base piece 1 is a single-piece profile in which are formed two longitudinal grooves 18 and having in the vicinity of the bottom of each groove two breakable zones 17 of small thickness. The linear base piece 1 is thus divisible in three different ways, so as to form either the linear base piece 1A T-shaped of Figure 43, or the linear facing piece 1 B of Figure 46, or the piece Linear facing 1 C of Figure 49.

With reference to FIGS. 42 to 44, the linear facing piece 2A, obtained after cutting the main facing linear piece 2 "', and the T-shaped linear base piece 1A, obtained after breaking the basic linear piece. 1, have in cross section similar geometries respectively to those of the linear facing piece 2 and the linear base piece 1A of Figure 1. However, unlike the linear facing piece 2 of Figure 1, the piece Linear facing 2A can be rigid and is not necessarily flexible or flexible.The linear facing piece 2A and the basic linear part 1A can be assembled in the same way as the linear parts facing 2 and base 1 to form a finishing accessory A intended to serve as a transition bar between two flooring having substantially the same thickness.

 With reference to FIGS. 45 to 47, the linear facing piece 2B, obtained after cutting the linear main facing piece 2 "', and the linear base piece 1 B obtained after breaking the linear base piece 1, can be mechanically assembled together by interlocking one into the other, and by longitudinally sliding the two parts relative to each other, so as to constitute the finishing accessory B of FIG. 47, the apparent face of which is formed by the facing piece 2B and which makes it possible to fulfill the same fitting function as the finishing accessory of FIG. 9. However, unlike the linear facing piece 2 of the finishing accessory of FIG. 9 , the linear facing piece 2A can be rigid and is not necessarily flexible.
