Description

SYSTEM FOR RECOVERING THE EDGE OF A PANEL OR THE LIKE

IN AN AMOUNT

  The present invention relates to systems for embedding the edge of a panel or the like, for example a pane of the "double glazing" type, in a profile-type upright, for example aluminum or any other metallic material, plastic, etc. It is already known systems for embedding the edge of a panel thickness E as a window, a double glazing or the like, on an amount consisting of a profile or the like.

  Such a system essentially comprises a groove in the form of a first "U" made in the upright, the width internally separating the two branches of the first "U" being greater than the thickness E of the panel, and a seal in the form of second "U", the overall width separating the two branches of the second "U" being at most equal to the inner width L of the first "U", the inner width of the second "U" being substantially equal to the thickness E and its overall height H being greater than the depth P of the first "U".

  The "U" gasket which is a flexible rubber sealing gasket or the like is generally positioned all around the panel so that the latter matches the entire inner wall of the second "U", then the panel thus provided with its gasket is in force in the groove in the form of a first "U" with its two branches projecting from the first "U" to form a sealing zone between the panel and the amount on each side of the panel, generally the inner and outer sides of the 'a window.

  However, such "U" joints have "U" legs of relatively small thickness because the space available between each face of the panel and the upright itself is thin. However, such small thicknesses are difficult to obtain in manufacturing and the "U" joint actually has varying branch thicknesses from one seal to the other, some of which are slightly greater than the available space, causing in difficult place of the panel equipped with its joints by creep or deformation of the joint. Thus, it happens that the upper part of the branches of the "U" can be housed in the slots provided for this purpose on the amount for a good seal.

  These deformations of the joint "U" generally prevent proper placement of the panel and do not provide a good seal around the panel, which is a serious drawback especially when the panel consists of a double glazing for a door, window or the like. Efforts to insert the panel can even cause the destruction of the seal, by tearing or the like.

  Also, is the present invention intended to provide a system for embedding the edge of a panel or the like, which at least substantially overcomes the aforementioned disadvantages of similar systems of the prior art .

  More precisely, the subject of the present invention is a system for embedding the edge of a panel or the like of thickness E in an upright, characterized in that it comprises: E a groove of depth P made in said upright, said groove being substantially in the form of a first "U", the width L internally separating the two branches of the first U being greater than the thickness E, E a first seal in the form of a second "U", the overall width separating the two branches of the second "U" being at most equal to the inner width L of the first "U", the inner width of the second "U" being substantially equal to the thickness E and the overall height H of the second "U" "being less than the depth P of the first" U ", said first seal being able to be positioned in the bottom of said groove, and É second and third key seals capable of being introduced respectively into the two spaces defined between of the ux limbs of the first "U" and the two opposite sides of the panel when said panel is plugged into the first seal in the first "U" shaped groove.

  Other features and advantages of the invention will become apparent from the following description given with reference to the accompanying drawings for illustrative but not limiting purposes, in which: FIG. 1 represents an overall view in vertical section of a 25 embodiment of the embedding system according to the invention, the edge of a panel or the like of thickness E in a post, applied to a sliding frame.

  Figure 2 shows an enlarged detail of Figure 1, centered on the embedding system according to the invention.

  It is pointed out that FIGS. 1 and 2 show only one embodiment of the object according to the invention, but that there may be other embodiments that meet the definition of this invention.

  It is furthermore specified that, when, according to the definition of the invention, the object of the invention comprises "at least one" element having a given function, the embodiment described may comprise several of these elements. Conversely, if the embodiment of the object according to the invention as illustrated has several elements of identical function and if, in the description, it is not specified that the object according to this invention must obligatorily comprise a number particular of these elements, the object of the invention may be defined as comprising "at least one" of these elements.

  Finally, it is pointed out that when, in the present description, an expression alone defines, without specific specific reference to it, a set of structural characteristics, [for example S = S (r, t, e, ...)] , these characteristics can be taken, for the definition of the object of the protection requested, when technically possible, either separately, [eg e, and / or t, and / or r, ...], or total and / or partial combination, [e.g. S (e, t, r), and / or S (e, t), and / or S (t, r), and / or S (e, r)].

  FIGS. 1 and 2 show a system for embedding the edge 1 of a panel 2 or the like of thickness E in an upright 3, specifying that this panel can be of any type and in any material, but that the system according to the invention finds a particularly advantageous application for embedding a window, for example a double glazing or the like as shown in the figures, in an amount of a frame for producing for example a window, a door, sliding door, etc., in a building.

  With reference to the figures, the system according to the invention comprises a groove 10 of depth P made in the upright 3, this groove being substantially in the shape of a first "U", the width L internally separating the two branches 11, 12 of this first "U" being greater than the thickness E. It further comprises a first seal 20 shaped second "U", the overall width separating the two branches 21, 22 of the second "U" being at most equal to the inner width L of the first "U", preferably slightly less than the latter, the inner width of the second "U" being substantially equal to the thickness E, ie slightly greater, or slightly less, or equal to to the thickness E, preferably slightly lower so that the first seal 20 can be placed in force around the panel and is held thereon by adhesion the time of placement of the panel in the groove 10, and the overall height H of the second "U" so lower than the depth P of the first "U", this first seal 20 being able to be positioned, as will be explained below, in the bottom 14 of the groove 10 and receive, by plugging, the edge 1 of the panel 2.

  The embedding system also comprises second and third key seals 31, 32 adapted to be introduced respectively into the two spaces 33, 34 defined between the two branches 11, 12 of the first "U" and the two opposite faces 5 , 6 of the panel 2 when it is plugged into the first seal, both being positioned in the groove 10.

  According to an advantageous characteristic of the invention, the first seal 20 comprises two chamfers 41, 42 made respectively at the two ends of its base 23 corresponding to the base of the second "U" connecting its two branches 21, 22, these chamfers shaped cut faces being provided essentially for, as explained below, promote the introduction of the panel provided with the first seal 20 in the groove.

  According to an advantageous characteristic, the first seal 20 comprises at least one cell 60 which extends into the base of the "U", the cell 60 having the function of allowing the seal 20 to be crushed, so as to provide a first seal 20 variable thickness, this variable thickness being able to compensate for wide tolerances of manufacture of a panel 2, while ensuring the contact of the seal 20 in the bottom of the groove 10, this also in the case of the vertical amounts of an opening . In addition, the cell 60 ensures a better thermal insulation of the device, the seal 20 may be in contact with the two parts of an amount 3 thermal break, which are at different temperatures, as shown on the figures. Preferably, the cell 20 will extend over the entire width of the first seal 20, as shown in Figures 1 and 2, to ensure a regular crushing over the width of the seal and better thermal insulation.

  It is specified that, when it is specified above that the overall width separating the two branches 21, 22 of the second "U" is at most equal to the inner width L of the first "U", it is a question of a functional theoretical characteristic, the practical reality of making the seal 20 to take account of manufacturing tolerances, this may cause an overall width separating the two branches 21, 22 of the second "U" slightly greater than the inner width L of the first "U" without this having any effect on the proper functioning of the system according to the invention, as will be explained later with the help of examples of assembly methods of the system according to the invention, which n ' was not the case with the system of the prior art described in the preamble.

  Preferably, as is more particularly visible in Figure 2, the thickness of the second and third key seals 31, 32 is at least equal to LE 2 otherwise slightly greater to ensure a good seal between the panel 2 and the amount 3 , as is necessary in the field of the realization of doors and windows or the like.

  Preferably also, the embedding system also comprises locking means 50 of the second and third key rings 31, 32 with the inner wall respectively of the two branches 11, 12 of the first "U" when they are introduced respectively into the two spaces 33, 34.

  According to a possible and preferred embodiment in terms of the manufacture of seals, these locking means for each key seal consist of a groove 51 made in the inner wall of a branch of the first "U" and a tongue 52 performed on the key seal to be locked relative to this branch so that, when the key seal is plugged into the corresponding space, the tongue 52 comes to be housed in the groove 51.

  To avoid possible tearing of the second and third seals 31, 32 out of the spaces 33, 34, it is advantageous that the tongue 52 and the groove 51 form an anti-tearing torque, the cross section of the tongue having the shape of a barb in the manner of a harpoon and the groove having a cross section of complementary shape.

  It is obvious that the height of the second and third key seals 31, 32 may be less than p - H but, very advantageously, it will be substantially equal to P - H so that, when they are introduced into the spaces 33, 34 two of their ends come into contact with the tops of the two branches 21, 22 of the second "U", and that their other ends 36, 37 are flush with the free edges 24, 25 of the two branches 11, 12 of the first "U". However, it is perfectly conceivable to leave a gap between the key seals 31, 32 and the seal 20, to absorb any deformation of the latter as explained below, and so that this deformation does not come to hinder the establishment. key seals 31, 32.

  It is furthermore advantageous that, in order to increase the seal between the panel and the upright, the embedding system according to the invention further comprises two shoulder heads 38, 39 respectively integral with the ends 36, 37 of the key seals 31 , 32 able to emerge from the groove 10 and flush with the free edges of the two branches 11, 12 of the first "U", the thickness of the portion of these shoulder heads adapted to come into contact with the free edges 24, 25 of the branches 11, 12 of the first "U", taken perpendicularly to the planes of the opposite faces 5, 6 of the panel 2, being greater than L 2 E so that this part comes at least partially overlapping the free edges of the two branches of the first "U" ".

  It is also preferable that the first seal 20 is made of a thermally insulating material, indispensable in the case of a post 3 with a thermal break as shown in the figure, preferably rubber or the like, for example EPDM rubber or equivalent preferably high density with a shore hardness of 80, and that the second and third key seals 31, 32 are also made of a flexible elastic material, for example EPDM rubber or equivalent, medium or low density, of a hardness shore of 70 for example or lower. In general, it is advantageous that, although having a certain elasticity, the material in which the first seal 20 is made is harder than that in which the second and third key seals 31, 32 are made.

  The system according to the invention for embedding a panel as a double glazing in an aluminum profile or the like forming an upright, is used for example in the following way: Firstly, the first seal 20 is placed around the edge of the panel 2, for example a double glazing, on the edges thereof to be embedded in a groove 10. The first seal 20 and placed on the appropriate edges of the panel 2, the latter, that is to say the double glazing as an example, is introduced into the groove 10, this introduction being advantageously facilitated by the presence of the two chamfers 41, 42. The height of the branches 21, 22 being defined in a necessary manner and sufficient so that the seal 20 adheres on the panel 2 the time of the establishment of it in the groove 10. The possible resistance of the seal 20 when placing the panel and provided with the seal 20, in the groove 10 is made minimal or null, to the extent that overall width of the gasket 20 is advantageously slightly less than the width L of the groove 10, this characteristic being made possible because the seal 20 does not have the function of sealing the system between the panel 2 and the amount 3, this function being provided by the key seals 31, 32. In any event, insofar as the seal 20 would force during the penetration into the groove 10 to the point of deforming, it would have no impact on the sealing function of the key seals 31, 32 separate from the seal 20.

  The two key seals 31, 32 are then introduced respectively into the two spaces 33, 34 to seal between the two opposite faces 5, 6 of the edge 1 of the double glazing 2 and the upright 3 which is generally a profile made of a material as aluminum or the like. The introduction of the two key joints is made in force so as to cooperate the tongues 52 and the grooves 51.

  Alternatively, it is possible to adopt the following mounting method: Firstly, the first seal 20 is introduced into the groove 10 to be pressed against the bottom 14 of the groove, noting that the introduction the first seal is favored by the presence of the two chamfers 41, 42.

  The first seal 20 thus placed, the panel 2, that is to say the double glazing by way of example, is introduced into the groove 10, then into the first joint between the two branches 21, 22 of the second "U". ". It should be noted that, thanks to the structure of the embedding system according to the invention, the height H of the second "U" can be relatively small and that the risk of deformation mentioned above is avoided.

  The two key seals 31, 32 are then introduced respectively into the two spaces 33, 34 in the same manner as with the first example of the mounting method described above.

  An advantage of the system according to the present invention is that it allows flat glazing, that is to say it allows the establishment of a panel in the groove 10 when the panel is flat, because the seal 20 has return legs 21, 22 which act as wedges for the insertion of key seals 31, 32, even when the frame or the amounts in which the panel is to be mounted is flat.

  From the above description, it is evident that, by its structure, the embedding system according to the invention no longer has the drawbacks mentioned in the preamble.
