Definitions

• the present invention relates to plates, in particular glass-type fragile material, equipped to be fixed on supports or to be interconnected by means of connecting elements.
• Such plates are intended in particular for the production of walls or furniture, a facade element, an interior design, consisting of substrates, in particular transparent substrates, for example glass substrates.
• these plates must therefore have holes at the points of attachment and / or connection. They can be reinforced, in particular by means of thermal or chemical quenching, to obtain the required mechanical strength (and, where appropriate, thermal resistance). The holes must then be made before the heat treatment.

• the main disadvantage of this type of plate lies particularly in the fact that the connection between the groove and its seal requires the use of an agent or an external action.
• the chosen adhesive In the case of bonding, the chosen adhesive must be deposited beforehand on the faces of the seal and / or the groove to be glued and then the faces of the seal and / or the groove are brought into contact, the mechanical joining of the together only after a given set time.
• This bonding technique is dependent on the setting time of the adhesive, and the resistance of the adhesive over time, the mechanical joining between the seal within its groove being able to deteriorate over time, in particular due to aging of the adhesive. glue (UV action for example) or due to a mechanical or chemical stress of the type of detergent or solvent etc .. on the inappropriate joint.
• German utility model DE 203 02 370 describes a connection system for glass plates, this connection system for securing with the aid of a connecting element cooperating through retention forms made on the edges of the plates. of glass. These forms of dovetail retention are inappropriate if the plate, as often, is to undergo heat treatment to improve its mechanical properties, typically quenching.

• FIGS. 4 and 5 show monolithic panes 1 and 2 which are provided on at least one surface portion, and at their edge 3, at least one groove, which has been formed before the quenching the glass parallel to the main faces of the latter and along the edge.
• edges of the transitions of the face forming the edge towards the two main faces of the window are broken in the usual way, for example by chamfering.
• the cross section of the groove is rectangular in a first portion adjacent to these remaining surfaces, and is rounded in a second portion forming the bottom of the groove. However, its bottom will be rounded well, to avoid any stress peak in the corners and minimize the notch effect of the groove.
• a blind cavity Inside this groove is made through a series of milling cutters with profile and toothing adapted (roughing cutter, semi-finishing, finishing) a blind cavity.
• the cavities may be of varied cross section, in particular circular, oblong.
• it is obtained from abrasive discs or abrasive grinding wheels. These abrasive tools are of course driven in rotation and are positioned on a pivoting or tilting head. Thus, by inclining the tool relative to the normal edge or edge of the glass substrate, and combining this movement with a feed movement, is obtained after several machining passes a desired groove or profile.
• the cavity is delimited by a flat bottom perpendicular to the main faces of the glass plate, and by a side wall connected to the bottom by a region of curved profile and retention, in particular concave, of concavity turned towards the inside of the cavity and with axial symmetry, then a short region oblong, to open at the remaining surfaces by a frustoconical region flaring outward.
• This region is thus, with the neighboring parts of the regions, a bead attachment or retention whose role is indicated below.
• the groove may also have an undercut cross section, if the corresponding manufacturing possibilities are available and the total thickness of the plate is sufficient.
• the groove formed on the edge 3 of each substrate is intended to receive a connection system 4 obtained by molding in a plastic material such as PVDF for example (polyvinylidene fluoride), or PA 66, or by a pultrusion operation. reinforcing fibers (glass fibers) and plastic fibers.
• connection system 4 comprises a projecting projection 5 connected to a substantially flat shoe 6.
• This connection system 4 is either monoblock or composed of several elements. It is elastically deformable, or plastically so as to allow its introduction into the groove.
• the outer face of the appendix 5 is connected to the bottom by a curved region whose shape allows it to come to marry that of the concave region of the groove.
• the arched region is extended by a wall of low height, which is intended to bear against the oblong region delimiting the groove, to end, after an inward recess, by another oblong region.
• connection system 4 comprises a shoe-shaped portion of generally parallelepiped shape of which at least one of the faces is provided with an appendage 5 projecting .
• connection system 4 to have a connection system 4, generally of U-shaped cross-section, and whose lateral parts of the U are provided with appendices 5 allowing the edges of the substrates to be joined to the edges and the central portion of which U, allows by wedging or the like mounting force of another substrate or a wall or a partition.
• the part forming the appendix 5 comprises projecting portions 7 of convex profile complementary to the profile of the concave faces made in the groove.
• convex portions 7 are made in one piece with the shoe and they are elastically deformable. Moreover, one could also imagine to prefabricate separately the shoe on the one hand with the convex parts 7 on the other hand and to assemble them later (clipping, gluing, fusion). This would possibly have the advantage that the hoof and convex parts could consist of different materials (especially also with different hardnesses).
• connection system 4 For mounting the connection system 4 in the groove of the plate 1 (the glazing or the like), it is sufficient to push "in force" the appendix in good position in the groove.
• the convex portions 7 are then elastically deformed.
• this connection system can cooperate with a rod or any other type of similar member to allow it to cooperate with another connection system for cooperating with another cavity of another plate to thus form elements (furniture or other).
• the connection system shown in Figure 3 is in the form of a yoke or soleplate intended to be connected to the ground or any other supporting structure through the orifices 8 through which means fasteners can be introduced, or the connection system can generally consist of any kinematic chain for connecting a plate of brittle material to a support.
• this kinematic chain may comprise a ball joint, possibly extended by a rod, an articulation, a box ...
• the assembly between a substrate 1 and a connection system 4 can be achieved by providing or admitting a set of expansion between the connection 4 and the substrate 1.
• the groove formed on the edge 3 of the substrate 1 has a characteristic dimension (here in particular a depth) substantially greater than the characteristic dimension of the appendix 5, so as to allow axial displacement along one way or another of the appendix 5 within the groove.
• This axial displacement of the system 4 and its appendix 5 with respect to the substrate 1 may be consecutive to phenomena of thermal expansion, or mechanical clearances resulting from the assembly of the substrates 1, 2.
• connection system 4 and the substrate 1 or 2 but more generally with a kinematic chain constituting an intermediate part or a set of intermediate part between a connection system and the less a substrate.
• the appendix 5 'of the connection system 4 is asymmetrical.
• This asymmetrical profile is particularly adapted to facilitate the mounting between a substrate 1 or 2 and a connection system 4 not by fitting the connection system 4 by one end of the groove formed on the edge of the glazing and then making slide the appendix 5 along the groove but positioning facing the appendix 5 'with respect to the groove in its final position and then making a slight rotational movement which allows the engament of the appendix 5' in the groove.
• connection system 4 carrying its asymmetrical appendix 5 'in the groove 3 is similar to a mounting between "2 parquet strips” by “clipping", the locking between the two parts being obtained when the substrate 1 and the system connection are positioned in the same plane, (assembly of Figure 7).
• Glass plates which have undergone a heat or chemical treatment are prepared in the following way: we start by cutting plates in unhardened glass; the cavities are machined at the intended locations (generally at least one surface portion of the edge of said plate), the heat or chemical treatment (in this case, quenching) of the plates is then carried out.
• the concave region of the lateral walls delimiting the cavities makes it possible to distribute the stresses that develop within the glass during quenching.
• the profile of this concave region at the level of the choice of the radius of curvature makes it possible to ensure that the quenching takes place without causing rupture of the glass in this region, avoiding having to discard plates.
• connection systems in the cavities.
• this setting up of the connecting elements is very easy because of the elasticity, or even the plasticity thereof.
• the plates can be delivered when they are already equipped with their connecting elements.
• connection system allows an assembly to be made between a frame or a supporting structure more generally and a plate.
• connection system serves for the assembly of multiple glazing. It can be a triple glazing (of course, a variant for double glazing can be deduced without difficulty from the previous one), the connecting element is triple, a central element and two lateral elements cooperating respectively with as many cavities made. in the songs of the windows.
• the choice of the material constituting the connection system is adapted to bring the mechanical strength to the assembly once mounted, so to provide, if necessary, a seal if the multiple glazing is assembled by incorporating a gas between the glazing. If necessary, the connecting elements are sealed at atmospheric pressure, insofar as may proceed to depression between the glazing.
• connection is relatively insensitive to manufacturing tolerances, the connection is removable and can withstand relatively high mechanical forces.
