Definitions
- the present invention relates to a furniture box formed of panels assembled edge to edge according to a joint with bastard tongue and tongue in which,
- a first and a second panel are assembled by the edge of the first panel coming against the inner edge of the second panel thus forming a dihedron, the first panel having a first orientation and the second panel having a second orientation in the plane perpendicular to the direction; of the edge of the dihedron formed by the assembly.
- the furniture boxes are formed by the assembly of panels, usually edge to edge.
- the assembly means of panels are very diverse ranging from complex assembly forms used in carpentry to a more simple assembly edge to edge, glued and reinforced if necessary by points and staples.
- the joints glued edge-to-edge often use spacers, such as tongues, tabs, placed in two complementary grooves and glued assemblies, (for example slats of elliptical or rectangular shape diffused under the trademark "Lamello").
- the present invention aims to develop a furniture box formed by the assembly of panels and whose realization of the assembly at the corners of the box, can be done in a simple manner, with a guaranteed result and without requiring special knowledge in the field of carpentry.
- the invention relates to a furniture box of the type defined above, characterized in that
- the first panel has on its edge, on the edge of its inner side, a bastard assembly tongue, leaving a singing support surface, and
- the second panel comprises along its inner edge a housing of complementary shape to that of the edge of the first panel with on the one hand a longitudinal assembly groove, complementary in shape to that of the tongue, and on the other hand a outer bearing surface beyond the groove to receive the edge-bearing surface of the other panel,
- the furniture box according to the invention assembles in a particularly simple manner since it is sufficient to join the various panels, for example the four panels constituting the parallelepipedal box.
- the box according to the invention does not require any assembly accessories said hardware, such as screws, pins, eccentric that complicate the packaging and preparation in the factory and also the assembly by the customer who, in principle, is not a specialist in carpentry assembly techniques.
- the assembly is done by simple casing, also the assembly angles (for example 90 °) are guaranteed because of the simple meeting of the panels.
- the meeting of the panels may be corrected, in a very simple manner so that the front and rear faces of the panels are perfectly aligned.
- the box has a bottom housed in a groove made near the rear edge of each of the panels, the assembly is even simpler since the panels are guided in their assembly also by the bottom of the box, engaged in the grooves. The introduction of the locking tabs in the box thus assembled with its bottom, completes the assembly.
- the assembly is just as simple by joining the panels, then locking their assembly to then put in place the bottom in the rabbet and which covers the ends of the locking tabs.
- the locking grooves open on only one side of the panels.
- the locking grooves preferably open on the back side of the panels, that is to say from the rear of the box so that the front face of the box reveals only the line of junction between the bastard tongue and its housing without revealing the channel formed by the meeting of the two locking grooves at each corner.
- the aspect of the furniture in frontage is of this fact net.
- the locking grooves can occupy the entire length of the edge of the panels and lead to the front side.
- the channel can also receive in this case a decorative element which underlines the corner of the furniture in front.
- the locking tab may have a length greater than the length of the channel if it must protrude forward or a length less than the length of the channel to allow the channel to open freely on the front face and possibly receive an element fixing, such as a pin, at the rear of an element decorating the front face of the box.
- the locking grooves have a rectangular section and the locking tongue has a rectangular section equal, with the clearance, to that of the channel formed by the union of the two locking grooves,
- the tongue is. thus tightly engaged in the channel and strengthens the assembly by locking it and compensating for any play.
- the locking tab ends at the rear by a tab forming a support or a limit stop engagement engagement of the tongue in the channel.
- This tab facilitates the introduction of the tongue into the channel especially if the section of the tongue is adapted closely to that of the channel thus increasing the bearing surface,
- the locking grooves are of rectangular section and the locking tongue has a section at most equal to the clearance, that of a groove to be placed in this groove before assembling the panels without exceeding the groove to be then pushed to the junction of the two grooves when the assembly of the panels is completed so as to lock their assembly.
- This tongue can be placed in the locking groove after manufacture of the panel so that the panels of a furniture box can be packaged and packaged without worrying about locking tabs that the end user will find and already installed, it will suffice after assembling the panels, pushing each locking tab to also enter the other groove forming the channel.
- This movement can be done simply using a rod slipped into the groove.
- This embodiment has the advantage of ensuring that the locking tongue occupies the entire length of the groove and that it will not lock before reaching the end of the channel, in case an asperity would be an obstacle accidental to the progression of the tongue along the channel.
- the bottom in the case of a box provided with a bottom housed in a peripheral groove formed near the edge of each of the panels, the bottom has a cut-out near its corners to allow the channel formed by the grooves to be disengaged.
- This embodiment makes it possible to closely adapt the dimensions of the bottom to the dimensions in height and replacement width defined by the peripheral grooves intended to receive it, so that the bottom is adapted closely to the dimension of the shape defined by the grooves. .
- the locking tab is terminated by a locking member hooked to the end of the dihedral of the box formed by the assembly of two panels by pressing on the edge and housing in the groove of the panels receiving the edges of the bottom to immobilize the locking tab.
- This locking member makes it possible to wedge the locking tab and to prevent it from protruding from the rear of the box under the effect of vibration or other movements to which the box can
- the locking member also has the advantage of wedging the bottom in the peripheral groove of the walls to prevent possible vibration of the bottom.
- This locking tongue provided with such a locking member is simply installed by a slight deformation of the locking member relative to the tongue to pass on the inner side of the surfaces of the dihedron formed by the junction of the two panels at the corner then let the locking member bear against the inner faces, against the top of the box (usually the back side) and in the peripheral groove.
- the locking member comprises a large base-shaped bracket to rest flat on the edge of the panels at their junction forming the dihedral assembly, this large base secured to the tongue of locking being prolonged by a dihedral shaped connecting portion coming to wedge against the underside of the dihedral junction of the panels and carrying a small base with projecting hooking slats, coming in the peripheral groove receiving the bottom edges.
- This embodiment of the locking member ensures an excellent wedging of this member against the inner side of the two panels at their junction.
- the small triangular base forms a bottom in the interior of the dihedral of the connecting portion and comprises a maneuvering notch.
- This notch allows to introduce the end of a lever forming tool such as the end of a screwdriver in the notch to slightly tilt or deform the small base of the locking member and extract the locking slats of the peripheral groove of the two panels to then easily pull the locking member with the locking tab.
- the large base protrudes from the dihedral shaped connecting portion of a width corresponding to the width of the bearing surface of the recess made in the edge of the panels.
- the large base of the locking member advantageously comprises a notch substantially to the right of the notch of the small base to receive the lever tool and prevent it from slipping on the long side of the large base.
- the locking member has a symmetrical shape with respect to the two-sector plane of the junction of the two panels against which it is applied.
- the locking tab is divisible to adapt to the depth of the piece of furniture and in particular, the tongue is subdivided by local sectional reductions delimiting segments, in particular segments of different lengths to manufacture only a type of tongue and adapt it to the depth of the furniture or boxes by simple removal of one or more segments.

- Figure 1 shows the assembly region of two panels 10, 20 according to the invention representative of the assembly of four panels of the box.
- a caisson is generally formed of four sides, two lateral sides, a top, a bottom and a bottom. But the invention is not limited to such a parallelepipedal structure whose panels are at equilibrium. The angle between two sides can be different from 90 ° and the panels can be assembled with 120 ° or 135 ° angles for octagonal or hexagonal sections.
- Such boxes can be made of a modular set or be used individually. The boxes can be oriented as is generally the case with the horizontal edges, but also with vertical edges to form for example tabletops, including coffee tables or seats.
- the panels 10, 20 have an inner face 10a, 20a and an outer face 10b, 20b,
- the first panel 10 has a bastard tongue 1 1, that is to say located in the extension of the inner side 10a of the panel 10.
- This tongue 1 1 extends over the entire length of the panel 10 and forms a front surface 12 and two lateral bearing surfaces 13, 14, one of which joins an edge bearing surface 15.
- the inner side 100 of the first panel 10, at the base of the bastard tongue 11, has a parallel locking groove 16 singing.
- the second panel 20 has near its edge, on the inner side 20a, a housing or cut complementary shape to that of the edge of the first panel, that is to say a housing forming the assembly groove 21 for receiving the bastard tongue 1 1 and beyond the assembly groove, an inner bearing surface 25,
- the assembly groove 21 is bordered by a large bearing surface 23 formed of two parts 23a, 23b and a small bearing surface 24.
- the large bearing surface 23 is provided with a locking groove 26 in a position homologous to that of the locking groove 16 of the first panel 10 when the two panels 10, 20 are joined, the bastard tongue 1 1 being introduced to bottom in the assembly groove 21 and the abutment surface 15 of the first panel 10 against the inner bearing surface 25 of the second panel 20.
- the locking grooves 16, 26 of the two panels 10, 20 are preferably stopped just before the end of the two panneaxax 10, 20, but opening through the other end of the panels. This makes it possible to introduce a locking tab 40 corn avoids that it exceeds one side of the assembly (the one below the plane of Figure 1 ⁇ so that the shape of the two assembly grooves 16, 26 does not appear on the edge of the two assembled panels 10, 20.
- the two panels 10, 20 once assembled form a dihedral whose edge is the direction of assembly.
- the first panel 10 has an orientation X and the second panel 20 has an orientation Y, these orientations being taken in the plane perpendicular to the edge of the formed dihedron, which is here the plane consisting of the. drawing sheet of Figure 1.
- the assembly of the bastard tongue 1 1 in the assembly groove 21 is in the direction Y and the locking of this assembly by the tongue 40 introduced into the channel 30 which is the union of the two assembly branches 16, 26 , performs locking in the X direction.
- FIG. 1 also shows that the internal bearing surface 25 of the second panel 20 is set back from the distance R with respect to the plane of the inner side 20a of the panel 20. Conversely, the abutment surface 15 of the first panel 10 is advanced from the distance A so that the bastard tongue 1 1 is shorter than the bastard tongue known.
- FIGS. 3A, 3B schematically show the realization of the assembly structure of the panel 20 and its assembly groove 21 with its locking groove 26.
- the assembly groove 21 is first formed with a milling cutter FR1 (FIG. 3A), the milling cutter rotating around a Y1-Y1 axis parallel to the Y direction while also removing the part in front of the milling surface.
- inner bearing 25 to form the recessed portion.
- FIG. 4 shows an example of a locking tab 40 of rectangular section, with a pointed front end 41 and having at its rear end a tab 42 serving as a support and driving abutment.
- the tab 42 also serves for disassembling the box to facilitate the extraction of the tongue.
- Figures SA, 5B of similar presentation facilitate the comparison of the assembly of the invention (Figure 5A) to the known assembly groove and bastard tongue ( Figure 5B). This comparison puts in. the essential characteristics of the invention: the locking grooves 16, 26 forming the channel receiving the locking tongue 40,
- one of the panels (100) has a long bastard tongue 1 1 1 and the other 200 has a deep groove 221 since the inner side 200a is continuous without shrinkage and that the edge of the panel 100 is not advanced on the part remaining under the bastard tongue 1 1 1.
- This comparison shows in the assembly of the invention the shape of the housing 21 of the second panel 20 which is not limited to the single assembly groove 21 but has a recessed portion R in front of the inner bearing surface 25 This recessed part R is transferred to the bastard tongue 1 1 which is shorter because of the advance A of its abutment surface 15.
- the recessed part R and the advanced part A are highlighted by dotted lines.
- FIG. 5C shows the assembly flat, jointed, using assembly accessories such as screws, dowel pins, eccentric, all these accessories are schematized here by a screw 240 joining the panels 130, 230.
- This assembly is complex to prepare and requires the accessories listed above.
- FIG. 6 shows a first embodiment of a parallelepiped box 300 composed of two side walls 20A, 20B of a bottom wall 10A and an upper wall 10B and a bottom 50. These walls are constituted by panels assembled by their sides by an assembly according to the invention.
- the isometric view of Figure 6A shows the front face.
- FIGS. 6B, 6C, 6D show details of certain parts of the wall and of the assembly, knowing that the assemblies of the four corners of the caisson are made in the same way.
- FIG. 6B shows the assembly groove 21 of the wall 20B opening at the front and revealing the internal bearing surface 25,
- FIG. 6C shows a detail of an assembly side of the panel 10A constituting the bottom wall of the box 300.
- This side corresponds to the bastard tongue 1 1 whose geometric characteristics are those already described in FIGS. 1 to 5.
- This FIG. 6C also shows the locking groove 16 formed at the base of the bastard tongue 1 1. This groove 16 terminates before the front face of the panel 10A. It does not open in the front face, but only in the rear face (not shown in this figure).
- FIG. 6D shows the appearance of the assembly of the two panels 1QA, 20B at the bottom right corner, not showing the two locking grooves forming the locking channel not appearing at the front face of the box.
- Figure 7 is a view of the rear face of the box 300 which, in this example, has a bottom 50 housed in grooves 51-54 made near the rear edge of each of the four panels 10A, B, 20A, B.

- the other panels 10B, 20B have grooves 53, 54 in the same position so as to form a peripheral groove which receives the edge of the panel constituting the bottom 50, by simple engagement by the form.
- Figure 7B shows one of the cut corners 55 of the bottom panel 50 so that once the bottom engaged in the grooves 51-54, the corner 55 does not protrude into the locking grooves 16, 26 of the panels assembled and prohibits the establishment of the locking tongues 40 in CH.-Q nl 30 closed by the assembly of the corners.
- Fig. 7C shows the groove 52 in the lower panel 10A locking groove 16 along the joining edge of this bottom panel 10A.
- Figure 7D is a view of the lower corner of the right side panel 20A showing the groove 52 receiving the edge of the bottom panel 50, This groove 52 does not cut the inner bearing surface 25 of the edge of the side panel 20A. since the groove 52 for the edge of the bottom 50 is at the same depth as the groove 26 receiving the locking tab 40 and that, as shown in FIG. 1, the locking groove has one of its sides in the extension of the internal bearing surface 25, simply because the locking groove is made by milling, which results in this coplanar arrangement,
- Figure 8 shows in its parts 8A-8C, various details of the further assembly and locking of the box 300.
- FIG. 8A shows the situation at a lower corner of the side panel 20B, the bottom panel 50 being engaged in its groove 51 and the cut corner 55 leaves the locking groove 16 free at the base of the bastard tongue. 1 1 on this side of the bottom panel 10A.
- the cutout portion 55 of the bottom panel 50 rises above the surface of the bottom panel 10A so as not to cut the locking groove 26 of the second panel 20B shown to the left.
- Figure 8B shows a rear view of the box 300 whose bottom 50 has been placed in the grooves 51-54 and the four panels 10A, B; 20A, B assembled by the engagement of each bastard tongue in its respective groove. This figure also indicates the locking tabs 40,
- FIG. 8C is a view on an enlarged scale of this locking tab 40 facing the locking channel 30.
- the locking tab 40 is constituted by a blade of a certain thickness terminated at the rear by a gripping tab 42.
- Figure 9 shows in its parts 9A-9D, a variant of box 400 which differs from the box 300 said. "with grooves" described in Figures 7 and 8 by its rabbet 61-64 receiving the bottom 70.
- the four panels 10AA, 10BB; 20AA, 20BB for assembly have a trailing edge 61-64 for receiving the bottom panel 70 whose corners are not cut at the location of the locking grooves 16, 26.
- Figure 9B shows the detail of a rear corner of the panel, lower 10AA with the locking groove 16 which opens at the rear above the portion forming the rabbet 61 (an overshoot of the lower edge of the panel).
- Figure 9C shows the lower shape of the side panel showing the rebate. The other corners of the side panels and the bottom panels and. higher, have a homologous structure.
- the rebate 61-64 receives the bottom panel 70 which is simply placed in the rabbet 61-64. It is fixed at. using staples or spikes 71 as shown in Figure 9D.
- one of the locking grooves for example the locking groove 26 houses a locking tab which does not protrude from the opening of the groove and after the meeting of the two panels, the bastard tongue 1 1 being fully in the assembly housing 21, it suffices to lower the locking lemugette by pushing it, in the locking groove 16 of the other panel 10, so that the groove constitutes a lock coming to the protruding into the locking groove 16 while projecting into the locking groove 26.
- the locking tab is preferably placed in the locking groove 26 which is parallel to the plane of the panel 20 rather than in the the locking groove 16 of the panel 10 because then it would be perpendicular to the plane of the panel and a depth of lock groove 16 too large weaken the tab stick arde 1 1; this is not the case for the locking groove 26 which can have a much greater depth without this weakening the future assembly,
- FIG. 10 shows another embodiment of the locking tongue 40 for the assembly of two panels 10, 20 which differs from that described above by the locking member 60 carried by the rear end of the tongue of FIG. lock 40 which remains identical.
- the edge 10-1, 20-1 of the two panels 10, 20 is provided with a stall forming a peripheral bearing surface 10-2, 20-2 on all the panels 10, 20 at the top. their singing 10-1, 20-1, usually singing the back side of the box.
- the assembled box is shown here lying in horizontal position.
- the edges 10-1, 20-1 with their recess have a shape that is slightly different from that which appears in the preceding figures, for example in FIG. 8C.
- the recess is a milled part which borders the internal side.
- the locking tab 40 shown engaged in the channel 30 (not shown) formed by the assembly of the two panels 10, 20, is provided at its upper end corresponding to the rear side of the tongue, a fastening member which is housed in the dihedron formed by the assembly of the two panels and hang on the one hand by leaning on the edge 10-1, 20-1, that is to say here the support surface 10-2, 20-2 of the stall and on the other hand, coming to engage by attachment slats 63-1 in the groove 51, 52 (53, 54) device made in the panels 10, 20 to receive the edges of the bottom 50 of the box.
- the locking member 60 consists of a large base 61 in the form of a square to bear on the edge 10-1, 20-1 of the panels 10, 20, here on the bearing surfaces 10-2, 20-2 formed by the recesses of the edges 10-1, 20-1.
- This large base 61 is connected to the upper end (according to the orientation of this figure) of the locking tongue 40; this upper end is in general the rear end of the tongue since the edges 10-1, 20-1 correspond to the rear side of the box through which the locking tabs 40 are introduced.
- the large base 61 is provided with a connecting portion 62 in the form of a dihedral coming to bear against the inner faces of the panels 10, 20 under the bearing surfaces 10-2, 20-2.
- This dihedral shaped connecting portion 62 has a height (h) corresponding substantially to the distance between the edge 10 - 1, 20-1 (or here the bearing surface 10-2, 20-2) of the edge of the groove 51, 52.
- the end of this connecting portion 62 carries a small base 63 of triangular shape, blocking the bottom of the dihedron and extending beyond the connecting portion 62 by two attachment slats 63-1. projection in the groove 51, 52 of the panels 10, 20 above the bottom 50.
- the peripheral branch 51-54 is generally wide enough so that the bottom 50 can be easily accommodated therein and the free space is then occupied by the attachment slats 63-1, 63-2 on both sides 62-1, 62-2 of the dihedral-shaped connecting portion 62.
- the small base 63 here occupies the interior of the dihedron by a part 63-3 interior provided with a notch 63-4 so as to allow the release of the locking member 60 and the extraction of the locking tab 40.
- a tool is shown schematically by the line 64, representing a lever-forming tool such as a screwdriver whose "lower” end is inserted into the notch 63-4 and which is pressed against the edge of the large base 61 to perform a lever movement by pushing the arrow F, to extract the attachment slats 63-1 of the groove 51, 52 and thus allow the locking member 60 to be pulled up with the tongue 40.
- a cut 61-3 To guide the tool 64 and prevent it from sliding on one side or the other against the long side of the large base 61.
- This unlocking movement is a pivoting of the connecting portion 62 around its junction with the large base 61 or even a pivoting of the whole of the locking member 60 around its connection with the end of the tongue. locking 40 or elastic deformation of these elements playing in different cases on a certain flexibility of the material.
- the locking member 60 is composed of a large base 61 at right angle whose side 61-1 is connected to the locking tab 40 while the other side 61-2 is free.
- the dihedral-shaped connecting portion 62 consists of two walls 62-1, 62-2 but according to a variant not shown, the locking member could be limited to the single wall 62-1 of the part of dihedral-shaped connection connected to the large base 61, itself substantially limited to its side 61-1.
- the small base 63 limited to its only side with the plate 63- 1 homologous to the side 61- 1 of the large base 61, In this case also, the locking member would bear against the edge 20-1 of the panel 20 or its bearing surface 20-2 according to the example shown and its plate 63-1 would come into the groove 52 above the bottom 50 to lock the locking tongue 40.
- the sides 61-1, 61-2 of the large base 61 protrude from the connecting portion 62 by a length substantially equal to the width (i) of the surfaces of support 10-2, 20-2.
- the establishment of the locking tongue 40 with its locking member 60 is shown by two steps in Figures 1 1 A, 1 1B.
- FIG. 11A shows the introduction of the locking tongue 40 into the channel 30, the end of the tongue 40 being still outside the assembly of the panels 10, 20.
- the locking member 60 is slightly spaced apart and is slid by the edge of its two attachment strips against the inner surface of the two panels 10, 20 until the plates 63- 1, 63 -2 arrive in front of the groove 51, 52 of the two panels 10, 20 above the bottom 50 and can engage.
- the underside of the sides 61-1, 61-2 of the large base 61 protruding from the sides 62-1, 62-2 of the connecting portion member 62 is then resting on the bearing surfaces 10-2, 20-2.
- the locking member 60 thus constitutes both a wedge for the bottom 50 and a locking means of the locking tongue 40 so that it can not escape towards the rear (side of the edges 10-1, 20-1) under the effect of the movements or vibrations to which the box could be subjected.
- FIG. 12 The sectional view of Figure 12 highlights the connecting portion 62 in the form of dihedral with its small base 63 extending on the "outer" side by the attachment slats 63-1, 63-2. This figure also shows the inner part 63-3 with the notch 63-4 and the locking tongue 40, cut by the plane I.
- the triangle drawn in broken line is the outline of the large base 61 which does not appear in this view in section from above.
- FIG. 13 is a bottom sectional view along the plane Si showing the dihedral shaped connecting portion 62, cut, as well as the locking tongue 40.
- the large base 61 with its two sides 61-1, 61- 2 appears as well as the notch 63-4.
- Figure 14 is a top view of the assembly showing by transparency the various elements already described above.
- the notch 63-4 appears due to the cut 61-3 made in the large base 61.
- FIG. 15 is a bottom view of the locking tab 40 with its locking member 60.
- FIG. 16 is a variant of the locking tongue 40 and its locking member 60 in which the small base 63 does not has no inner portion 63-3 nor notch 63-4, the other parts identical to the previous ones have the same references.
- the tongue 40A is a splittable tongue so as to easily adapt its length to the depth of the box from a tongue of uniform length.
- This tongue is subdivided by local reductions section 41- 1, 41-2 (41-i) distributed regularly or irregularly over the base length of the tongue 40A and defining segments (42-1, 42-2 ... 42-i) of length Li equal to or different for the best adaptation to the depth of a box.
- the segments thus delimited have a length Li and section reductions 41-i consist of notches made by molding the tongue 40A.
- Section reductions 41-i have rounded surfaces A1B 1 (AiBi) so as to avoid any attachment in the channel formed by the assembly of the two panels of the box receiving the tongue.
