Definitions

  • the present invention relates to an assembly element comprising an upper plate having a geometric shape determined and at least a first lower plate of dimensions generally similar to those of the upper plate, this first lower plate being fixed under the upper plate and being arranged so as to form at least one overflow zone which, on a part of the circumference of the upper plate, protrudes beyond the edge of this top plate and at least one recess area which on another part of said periphery, is set back from the edge of said top plate.
  • the assembly element covered by the invention is used for coating a flat surface (e.g. the floor or walls). It is an element inexpensive and quick and easy to set up.
  • the assembly element presented in this patent FR 1 268 529 is relatively thick, its total thickness being for example of the order of 23 mm.
  • the overflow areas of the first bottom plate of a given element are embedded in the grooves that form, between the upper plate and the second lower plate, the withdrawal zones of the first lower plate of the adjacent element.
  • this first plate is relatively thick and rigid (for example a medium hard material of 5 mm thick), which ensures correct and relatively easy assembly, the tongues formed by the overflow zones of the first bottom plate of an element being rigid enough to be easily embedded in the grooves formed by the withdrawal zones of the first bottom plate of an adjacent element, grooves themselves high enough to be visible and easily reached.
  • the upper plate for example wooden, has a thickness of about 9mm. So it's rigid, so that the parts of this plate which are overhanging in relation to grooves formed by the recess areas of the first lower plate remain flat without having a tendency to fold back, so that these grooves remain perfectly accessible.
  • the grooves would not be high enough to be easily accessible and overhanging top plate areas would partially hide them and thus hinder the insertion, in these grooves, overflow areas of the first lower plate.
  • the invention aims to improve the known assembly elements having an upper plate, a first lower plate and, possibly a second lower plate, to remedy the disadvantages mentioned above and facilitate the assembly of the elements by compared to others, even when the different plates which components have small thicknesses, in particular of the order of 0.3 to 1.5 mm.
  • the invention applies to an assembly element of the type mentioned above with reference to FR 1 268 529 and provides that the or the overflow zone (s) of the second lower plate relative to at the first lower plate also protrudes beyond the edge of the top plate.
  • the fixing tab (s) of an element are directly accessible when the element assembly is placed on a surface against which the second bottom plate. So, to set up a second assembly element with respect to the first, it suffices to place, on a fastening tab of the first element, a positioning tab of the second element and move this second element by exercising light pressure on it to press it against the surface to be coated, so sure to insert the positioning tab of this second element in the positioning groove of the first, even if the surface to be coated has irregularities.
  • fixing tabs serve to guide the placement of an assembly element with respect to another. They can also be used for fixing assembly elements since, being both directly accessible and in contact with the surface on which the elements are placed, they can receive fasteners such as screws, nails, staples or the like.
  • the zone (s) of withdrawal of the second plate lower extends, not only in relation to the edge of the first lower plate, but also compared to that of the top plate. This is particularly the case when the geometry of the second bottom plate is virtually identical to that of the upper plate and / or when it is desired to make an assembly adjusted various elements by placing their upper plates respective edge to edge.
  • the invention applies to a connecting element comprising an upper plate having a perimeter of determined geometric shape comprising several segments and a bottom plate having substantially the same surface than the upper plate, this lower plate being fixed under the upper plate and being arranged so as to form at least one overflow zone which, on a part of the periphery of said plate higher, protrudes beyond the edge of the latter and at least one setback area which, on another part of this perimeter, is set back relative to the edge of said upper plate.
  • This element includes a single bottom plate.
  • the difficulties of assembly previously mentioned also affect elements of this type, especially when the thickness of their plates is small, on the order of 0.3 to 1.5mm.
  • elements with only two plates there is a risk that the elements lift at least partially from the surface on which they are posed.
  • the invention aims to remedy these drawbacks.
  • the lower plate has a periphery having notches and the fact that said lower plate is arranged so as to form at least one overflow zone and at the minus one setback for each main segment of the perimeter of the top plate.
  • the segments around the top plate can be straight or partially curved.
  • "Main segments” means understand the segments which, taken together, form the most large part of the periphery of the upper plate. This can by example have the shape of a rectangle of length much greater than its width, in which case the "main segments” equipped, each at least an overflow zone and at least one withdrawal zone, can be the longitudinal sides of this rectangle.
  • the top plate can have a polygonal shape, in which case the segments forming its periphery are rectilinear.
  • each side of the bottom plate may have a notch providing an overflow area and a setback area for each segment around the top plate or only for its main segments.
  • overflow and withdrawal areas are placed so than an overflow zone, respectively a setback located on one side of the element corresponds to an area of withdrawal, respectively an area overflow located on the other side.
  • overflow and withdrawal zones will be respectively called “positioning tabs” and “removal of positioning”.
  • first element on a surface with put on.
  • positioning tabs can be used to fixing since they are directly accessible, they are at contact of the surface to be coated and that they can receive fasteners such as nails, staples or the like.
  • one cleans an area of the plates that is in contact with the surface to be coated, which protrudes from the top plate, which thus facilitates the positioning of the elements and can be used to fix them.
  • the element assembly is carried out using laminated or fixed plates one to the other by any suitable means, such as welding, for example by ultrasound or high frequencies. It can be set up with other elements of the same type, the top plate of which has the same geometric shape or a complementary geometric shape, for coating a surface.
  • the assembly will therefore be very simple, by inserting positioning tabs in grooves provided by the recesses positioning.
  • the cost price of the assembly elements can be low if appropriately chooses the materials constituting the various plates.
  • AT In this regard, one can choose a noble or relatively expensive material for make the top plate and use much less material costly to make the lower plate (s), invisible or practically not visible once the coating has been made.
  • the operation industrial consisting in fixing the various plates together, by example by laminating, does not increase prices excessively returns.
  • the fact of making the tongues and grooves not by machining but by laminating or equivalent fixing providing areas of overflow and areas of withdrawal allows make the tongues and grooves while retaining a thickness total for the extremely weak connecting element, often incompatible with machining operations, simultaneous extrusion of means of attachment or coextrusion (simultaneous or subsequent) of tabs on pre-existing plates.
  • an overflow area located in a given region of the element corresponds to a withdrawal zone located in an opposite region.
  • the parts of the periphery of the upper plate on which the first lower plate or the single lower plate respectively forms the overflow zone (s) and the zone (s) of withdrawal respectively substantially describe the half of that perimeter.
  • the positioning of the assembly elements one by compared to others is done in a balanced way on practically the entire circumference of the upper plate since, over substantially the half of this circumference, is provided a tongue capable of being inserted in one or more grooves made in one or more elements adjacent, while, on substantially the other half, is provided a groove in which one or more tabs are inserted equipping one or more other adjacent elements.
  • this layout further limits the vacuum areas under the upper plates of the various elements assembled.
  • the upper plate has the form of a polygon and the overflow zone (s) constituting the tabs are arranged on at least two adjacent sides of this polygon.
  • the bottom plate or, for the first embodiment, one of the lower plates has centering cuts of complementary shapes located in opposite regions of their respective edges. This will ensure a perfect alignment of the elements in relation to each other, avoiding all risk of error during installation. Tabs and grooves will not indeed correctly fit into each other only when the complementary centering cutouts will cooperate with each other.
  • the connecting element advantageously has a thickness total between one and four millimeters, thickness for which it it is not possible to use conventional means of machining or coextrusion to form complementary grooves and tongues.
  • the arrangement according to the invention is particularly suitable for plates whose thickness is at most equal to 1.2 mm, advantageously between 0.3 and 1 mm.
  • FIG. 1 shows an assembly element 10 according to the invention, which comprises three superimposed plates.
  • the top plate 12 has a specific geometric shape which, in this case, is that of a rectangle.
  • the first lower plate 14 generally presents the same size as the top plate 12 and the same shape geometric. Its upper face is glued to the lower face of this top plate.
  • the plate 14 is arranged so as to form at minus an overflow zone (or "positioning tab") 14a which, on a part 12a of the periphery of the upper plate 12 exceeds beyond the edge of this plate.
  • the plate 14 forms at least a withdrawal zone 14b (or “positioning withdrawal") which, on a part 12b of the circumference of the upper plate 12 is set back by compared to the edge of this top plate.
  • plate 14 is arranged so that two overflow zones 14a and 14c protrude beyond two parts 12a and 12c of the periphery of the plate 12, and that two withdrawal zones 14b and 14d are set back by compared to two edges 12b and 12d of the plate 12.
  • parts 12a and 12c of the periphery of the plate 12 on which extend the positioning tabs 14a and 14c substantially describe half of this perimeter
  • parts 12b and 12d of the periphery of the plate 12 on which the recesses of positioning 14b and 14d also correspond substantially to the half of that perimeter.
  • the first lower plate 14 has the same geometric shape as that of the upper plate 12 and that the zones overflow and shrinkage are obtained by shifting the plate 14 relative to the plate 12 in a determined direction D.
  • the shift direction advantageously corresponds to one of plate diagonals.
  • the offset direction D is defined by the sum of two vectors, respectively Da and Db, respectively parallel to two adjacent sides 12a and 12c respectively of the periphery of the plate 12. Due to this offset, the overflow zones 14a and 14c extend actually on slightly less than the sum of the sides 12a and 12c of the plate 12, since the tongue 14a extends on the side 12a minus the value of the component Da of the offset, and that the tongue 14c extends on the side 12c minus the value of the component Db of the offset. On the other hand, the withdrawal zones extend over all of the sides 12b and 12d increased by the values Da and Db.
  • the plate 12 having the shape of a polygon in this case a rectangle
  • positioning tabs 14a and 14c are arranged on two adjacent sides of the polygon, while the setbacks of positioning 14b and 14d are arranged on two other adjacent sides.
  • this advantageous feature could remain valid if the plate 12 had the shape of a polygon different from a rectangle having, the if necessary, more sides.
  • the invention is particularly suitable for plates having the shape of polygons whose sides are in even number.
  • the positioning tabs are fitted advantageously a series of adjacent sides representing half of the sides of this polygon, while positioning indentations equip the other sides.
  • the element 10 further comprises a second lower plate 16 which has dimensions generally similar to those of the upper plate 12 and the first lower plate 14.
  • the face top of plate 16 is glued to the underside of plate 14.
  • This plate 16 is arranged so as to form, in the region of tabs 14a and 14c, a withdrawal zone (or “fixing withdrawal”) which extends back from the edge of the plate 14. More precisely, two withdrawal zones, respectively 16a and 16c are thus formed, respectively under the tabs 14a and 14c.
  • the plate 16 has a zone of overflow (or “fixing tab") which protrudes beyond the edge of plate 14 and beyond the edge of plate 12. More specifically, two overflow zones 16b and 16d respectively, are respectively formed in the region of withdrawals 14b and 14d.
  • the fixing tabs protrude not only beyond the edge of the first bottom plate, but also beyond that of the top plate. So when the element is placed on its support, the tongues 16b and 16d are directly accessible. These tabs can have a double role. On the one hand, their upper faces constitute surfaces of guiding which will facilitate the insertion of the positioning tabs in the positioning grooves. On the other hand, they can be used for fixing by playing the role of support for fixing elements such as screws, nails, staples, or the like (in this case, plate 16 may be wavy or at least have recesses to accommodate the heads of the fasteners).
  • the upper plate 22 of the element 20 is adjacent to the edge 12a of the upper plate 12 of the element 10. If we consider that to carry out the assembly, this element 20, its fastening tab 26d protrudes beyond the edge 22d of its plate upper 22. Under these conditions, to set up the plate 12, it just place the end of the positioning tab 14a on the 26d tongue (which then acts as a guide) and leave slide the tongue 14a into the positioning groove made by the removal of the first lower plate 24 from the element 20, between the plate upper 22 and the tongue 26d. So even if the surface of the support on which the plates are assembled has irregularities, the guide and the establishment of the element 12 is done without difficulty. Finally, in the corner region between the positioning tabs 14a and 14c, these can be inserted into the fixing grooves made by the withdrawals of the first lower plates 34 and 44 of the elements 30 and 40.
  • the fixing recesses extend indented not only relative to the edge of the first bottom plate, but also compared to that of the upper plate.
  • their second lower plates can touch each other, without preventing their top plates do too.
  • the positioning tabs and, positioning recesses, respectively extend over edges adjacent to the polygon giving its shape to the top plate.
  • the fixing tabs and, respectively, the setbacks are in the region of adjacent edges, region opposite to that in which the tabs of positioning.
  • the offset D of the first lower plate by relation to the upper plate is defined by the two vectors Da and Db.
  • the offset of the second lower plate 16 with respect to the plate 14 can be defined by the same direction D, but in the opposite direction.
  • the first lower plate 14 is positioned by shifting it of the vector D with respect to the upper plate and we position the second lower plate by shifting it from the opposite of this vector by compared to this top plate.
  • the simplest embodiment to obtain the assembly of figure 2 consists in choosing these offsets as indicated above and to choose plates 12, 14 and 16 of substantially identical dimensions.
  • Figure 3 shows another method of assembly, in which the upper plates 12 ', 22', 32 'and 42' of the various elements are not contiguous. Indeed, a clearance J is formed between the edges opposite these different plates to give the appearance of joints similar to those found in classic tile assemblies floor tile.
  • This type of assembly is obtained by providing, in each of the directions defining an assembly plane, at least one of the first and second lower plates of each assembly element of dimensions substantially equal to the sum of the dimensions, viewed in the same directions, from the top plate and a predetermined value which defines the play J.
  • the directions defining the plane of assembly are actually the general directions of the joints between the plates, respectively d1 and d2. So, considered in parallel with the direction d1, i.e. parallel to the edge 12'a of the plate upper 12 ', the dimension l16 of the plate 16' is substantially equal to the sum of the dimension l12 of the plate 12 'in the same direction and of the set J. Similarly, considered in the second direction of joint d2, parallel to the edge 12'b of the plate 12 ', the dimension L 16 of the plate 16 is substantially equal to the sum of the dimension L 12 of the plate 12 in the same direction and from the game J.
  • FIG. 3 we have chosen to endow the first lower plate 14 'of the same dimensions as the upper plate 12 '.
  • This second option is actually to assemble the elements so that their first lower plates are joined, while providing joints of width J between the upper plates.
  • This second option is also preferable both from the point of view of the final aesthetic aspect of the assembly as that of the seal.
  • Figures 4 and 5 show variants in which at least one of the first and second lower plates of the element assembly presents centering cutouts complementary, located in opposite regions of these edges.
  • the plate 112 has the shape of a polygon and is broadly analogous to plate 12 of the figure 2.
  • the first and second lower plates, respectively 114 and 116 have roughly the same shapes and the same dimensions that the plate 112, except that the first plate 114 has centering cutouts. More specifically, on some of its sides (in the sides 114a and 114c), it has projecting fingers of point-shaped centering 115a and 115c. On the other sides (in the species sides 114b and 114d) it has centering recesses, 115b and 115d respectively. Withdrawals 115b and 115d have a form adapted to accommodate fingers 115a and 115c. This is what is meant by "complementary shapes" of centering cutouts.
  • the centering finger 115a will be embedded in a centering shrinkage 125d located on side 124d of the first plate lower 124 of the adjacent element 120. This makes it possible to correctly center the elements relative to each other and align the sides not adjacent, for example 112c and 122c, upper plates 112 and 122. Of course, one could choose to make the cuts of rather centering on the second lower plate of the elements assembly to obtain the same centering effect. The cuts are arranged so that a centering finger located on a given side of plate 114 or 116, corresponds to a centering shrinkage located on the opposite side.
  • the shape of the plates represented being that a square or a rectangle, the centering fingers are arranged on two adjacent sides, while the centering recesses are located on the two others.
  • the cuts of V-shaped centering can be used.
  • Figure 6 shows a more complex assembly which can be obtained according to two variants.
  • the first variant uses an upper plate 312 made up of made by two elementary plates 321 and 322, both fixed on a same first lower plate 314 (for simplicity, we do not have shown the second bottom plate).
  • line 313 marks a real apparent joint between the elementary plates 321 and 322.
  • the plate 314 can have the same shape and same surface (apart from taking into account the manufacturing tolerances and possibly assembly in mode not joined) that the assembly 312 constituted by the elementary plates 321 and 322 and be offset from this set in one direction substantially diagonal of the elementary plate 322.
  • a second lower plate similar to plate 314 can be fixed under the latter and offset from it in the same direction but in the other direction.
  • This variant allows assembly using 310 elements identical to each other, while giving the appearance of an assembly of plates of non identical shapes, but complementary (in the example shown, the elementary plates 321 have the shape of discs while the elementary plates 322 have generally the shape of squares whose corners are hollowed out in an arc of circle.
  • the element 310 includes a disc-shaped top plate 312' and a first lower plate 314 ', also disc-shaped, as well that a second bottom plate not shown.
  • Element 310 " includes a 312 "top plate and a second plate lower not shown.
  • the lower plates can be offset from the upper plates.
  • Figure 7 shows another assembly variant in which the elements have the form of polygons which, in this case, consist by irregular hexagons.
  • the element 410 comprises a plate upper 412 having the shape of a hexagon, a first plate lower 414 having substantially the same shape and the same dimension and offset in a direction F with respect to the top plate, as well that a second lower plate 416 also having substantially the same shape and size and offset from both first in the same direction F, but in the other direction.
  • the various assembly elements are assembled with elements having the same shape.
  • each element assemble by embedding the tabs positioning in the positioning grooves on several sides at a time it is better that the offset direction of the plates lower than the upper plate is not parallel to any side of the hexagon defining the shape of the top plate. So, as in the example in figure 1, the offset direction can be defined by the sum of two vectors respectively parallel to two adjacent sides of the hexagon.
  • the areas of overflow are arranged on adjacent sides of the polygon. Given the particular shape of this polygon, which has more from four sides, we can also get an assembly with perfect support of the elements by making the zones of overflow on sides a, c, and e of the polygon and setbacks on the sides b, d and f.
  • Figure 8 shows yet another assembly variant, in which the shape of the upper plate 512 of the elements 510 is that of a more complex polygon. It is indeed a polygon, two of which main sides are parallel, while the other sides are crenellated.
  • the positioning and fixing, as well as positioning and fixing recesses are simply obtained by suitably shifting the first and second lower plates 514 and 516 which may have the same shape and substantially the same dimensions as the top plate 512.
  • This provision may have the advantage of rendering practically invisible the junctions between the different upper plates when the elements are assembled.
  • these upper plates can have a decoration reminiscent of the form of briquettes. We can obtain this decoration by making the upper plate in the form of a single piece and by printing on the latter lines having the appearance of the joints.
  • the notches on the sides of the plates are parallel to the joints 513, and their spacing is compatible with the length of the briquettes dummies or elementary plates 512a, 512b. Once the assembly finished, the areas of junction between the upper plates of the different elements will merge with the joints 513.
  • the expression "upper plate” designates all of the plates elementary fixed on the same first lower plate. So the surface of the upper plate is substantially equal to the sum of surfaces of the elementary plates (possibly increased by surfaces of the intervals between these plates).
  • the indication mentioned at the beginning of this text according to which the first lower plate (respectively the second bottom plate) has "roughly" the same dimension as the plate upper must be taken in the broad sense. It means that surfaces of these plates are practically the same, disregarding manufacturing tolerances and, in the case of assembly in mode not joined, surface differences necessary to define the width assembly joints. Likewise, this indication should be considered as satisfied if, for example as a result of cuts made in the overflow areas, the surfaces of the bottom plates are while preserving the existence of the positioning tabs and fixing.
