Description

vertical section (9), of substantially square horizontal section, which carries the

roller (22).

  Dry-glazing joint with dual hardness, its method of

manufacturing, and its applications.

  TECHNICAL FIELD OF THE INVENTION The present invention relates to the technical sector of dry glazing joints and, in general, joints between a glazing (or a solid unglazed panel or similar panels) and a support or frame or

  support in wood or another material of hardness comparable to wood.

  The glazing and its support can compose a window, a door, or any other element of this type, windows, facades, ade, curtain walls, and be fixed or opening in any way (pivoting or tilting, etc ...). All of these options will be referred to here as "windows," or

  c glazing> for simplicity, including in the claims.

  Generally, the windows are placed in a frame to form the glazing, and generally the frame is made of wood, in a known manner. However, those skilled in the art will immediately understand that the invention also covers other types of frame, such as plastic frames of hardness comparable to that of wood used in glazing, such plastics being known to man to scour. Similarly, the frame may be of metal or alloy, and such materials are, in the field, also well known to those skilled in the art. Also, the glass can be placed in the frame by a craftsman, that is to say on the charffer, or the complete glazing can be prefabricated factory or workshop. We will designate the whole by

  cc framework "for simplicity, including in the claims.

  The windows can, according to the invention, be absolutely arbitrary, that is to say

  simple, double glazing phonic and / or thermal, anffeffracffon, or metal panels, siding, and the like, the set being designated

  here by "windows" for simplicity, including in the claims.

  Technical problem posed: The general technical problem that is posed is that of watertightness, especially rainwater, between the "glass" and its "frame", and so

to "liquids".

  It is known that the skilled person naturally uses more or less flexible joints, of various shapes, that are available between the glass and its frame. These joints are placed in the gap between the window and the frame, including the window and the wooden frame, possibly by stuffing this

  I nterval the, before, by a putty.

  PRIOR ART: In the prior art, it was first used a pot putty applied to the spatula, then a strip of extruded mastic, preformed, a bottom seal (adhesive foam and cartridge type silicone seal), or an extruded joint in

  cellular foam, and similar well-known products.

  Also known, more recently, so-called "monodureté" seals which consist of a preformed extruded strip obtained from a single material, generally a styrene-butadiene rubber type zo known as the "SBR", which is cut or extruded, and which is placed after the mastic.The material may preferably, in the building, be

  an "EPDM" rubber (ethylene propylene diene monomer).

  A prior art of the type is shown in FIG.

desfigures 1A, 1B, 1C and 1D.

  s Note: in all the attached figures, the same references designate the

same elements.

  In FIG. 1, which consists of FIGS. 1A to 1D, there is shown (FIG. 1A) a double glazing composed of two panes 1, with a vacuum or an air knife 4, and an internal profile 10, placed in a frame 2 (for example of wood). Erase the wood and the glass, the gap is filled either by a preformed tape sealant or a general reference seal 3 (notammént extruded or calendered) shaped such as for example shown in Figure 1, that is to say for example, (not fixed to three flexible lips in the shape of "W" (or of rectangular section in the case of a calendering) .The important aspect of the shape, vis-a-vis the problem posed (water tightness). water or other liquid), resides o in the profile of the upper part or upper lip 5. The shape of the pint is studied so that, in theory, the lip 5 extends towards the glass the beveled upper part 11 of the wooden frame that is to say that all of said part 11 of the frame and said upper lip 5 of the seal must not present a solution of continuity at the level of the upper surface.

  5.3 joints are for example extruded foam EPDM type.

  As is known to those skilled in the art, the slope of the frame bevel (face

  higher 11) is of the order of 15.

  This also applies to another type of prior art, shown in FIG. 1B, where the seal is a variant of FIG. 1A, with four lips 5 zo (upper) and 6, 7 and 8 (irreferential), and a protuberance or "tail fir" 9 flexible, intended to cooperate in a known manner with a groove or groove (not shown because known and obvious) formed in the face

  internal (that is to say facing the glass) of the frame 2 (opening or pareclose).

  In addition, to prevent their elongation at the time of installation, these z profiles benefit from an anti-elongation glass wire embedded in the rubber

  or an armed adhesive or similar solution.

  Figures 1C and 1D show the result that is generally obtained with

such seals of the prior art.

  In Figure 1C, the seal is placed too low, and there is a groove 6 o the water so (or other liquid) will stagnate. This water, on the one hand will degrade the wood, and on the other hand will infiltrate any crack, irregularity etc ... of the frame (wood or other material), and / or by capillarity, and all this more than wood (when

  the frame is made of wood) has been degraded.

  In Figure 1D, in an attempt to avoid the above disadvantage, the seal was deliberately placed too high, which is unsightly. This position can also be accidental, with the same result. Attempts have been made to overcome these serious drawbacks with a completely flexible "bonnet" product, for example as shown in FIG.

  Figure 2 (also of the prior art).

  This seal is positioned as those of FIG. 1, but comprises a rigid central vertical part 12, 3 flexible lips 5, 6 and 7, and a flexible "horizontal" cap 1 1 intended to prevent the seal from being driven in. too deeply as in Figure 1C, and to ensure a recovery of the interface frame (pareclose) / seal to prohibit any water infiltration along

of this interface.

  These glazing joints, usually in white or brown PVC, which have a rigid part to prevent the lengthening of the profile during installation, have the particularity of being implemented in a manner similar to conventional profiles but benefit from 'a more elaborate technique, and a

Work faster.

  To the knowledge of the applicant, this product has been mentioned but never

  has been marketed because it has the same disadvantages.

  There is therefore a significant and recognized need for a seal that is easy to manufacture, easy to install, leading to a good seal and in particular preventing any infiltration of water or moisture along the frame interface (especially

  wooden frame, but not limited to) / joint.

  In the prior art, adhesives of the acrylonic adhesive type with reinforcement have been used which prevent them from being lengthened during laying, and these products may also be used according to the invention, as well as any usual product of the invention.

  SUMMARY OF THE INVENTION: The invention relates to a "glazing" seal intended to cooperate with a "frame", characterized in that it is a seal for dual hardness type comprising (as for example, non-limiting, shown in Figure 3), a rigid vertical portion 20 extended by a "rigid return" 21 adapted so that its underside covers at least partially, and cooperates in abutment at _ covering, with the upper face 11 beveled of the frame 2 (pareclose), the vertical portion 20 having at least one flexible upper lip 5, preferably at least two flexible lips o upper 5, and intermediate 6 applying against the glass, the upper lip having a "free" portion 5A intended to be applied against the window, and a "return" portion 5B adapted so that its lower face 35 applies to (that is to say covers), and cooperates with, the upper fa_

said rigid return 21.

  Preferably, part 5B has part 5C (FIG. 5) which overflows

  outward beyond the outer edge of the rigid return 21.

  Exterior designates in all the text the direction which moves away from the glazing, and

  interiordesigns the direction that goes to the glazing.

  Reference is made in this field to FIGS. 3 (general view in section), 4 joirt

  co according to the invention alone, and 5 (enlarged view of the assembly of Figure 3).

  The invention therefore relates in the first place to a "glazing" seal 1 intended to cooperate with a "frame" 2, characterized in that it is a glazing seal, dual-hardness, of the type comprising a rigid vertical portion 20 extended at its apex and to the "outside" by a "rigid return" 21 z adapted so that its interior overlaps at least in part, and cooperates in abutment at the level of _ recovery, with the fa_ upper bevel 11 of the frame 2 (pareclose), the vertical portion 20 having at least one flexible upper lip 5, preferably at least two upper flexible lips 5, and intermediate (that is to say, below or below that , the lip 5) so 6, applying against the window, the upper lip 5 having a "free" portion 5A << inside "intended to be applied to the window, and an" return "part 5B" outside , adapted so that its lower face applies to (i.e. covers), and co-operates with, the upper side

dud, t rigid return 21.

  Detailed description of the invention

  According to a particular embodiment, the joir, t according to the invention comprises said upper flexible lip 5 with return 5B, and optionally 5C, and an intermediate flexible lip (that is to say located under the upper lip 5) 6. According to another particular and nonlimiting embodiment, the seal according o o the invention further comprises a lower lip 8 facing upwards.

like the lips 5 and 6.

  In still another embodiment, the invention comprises two intermediate flexible lips 6, 7 oriented like the lip, or in the form of a "V", the one (6) facing upwards. The other (7) downwards According to another particular embodiment, the lower lip 8 and / or

  intermediate (7) is oriented downwards.

  This is only possible when the seal is laid using one or more adhesive strips, that is to say is placed and fixed on the inside

  or internal frame BEFORE the installation of the glazing.

  zo When the seal according to the invention is cor horn milking placed joint "jam", that is to say AFTER the installation of the glazing, and without adhesive strips (the seal is simply sinking or "stuffed"> , in the interval between the vHrage and the frame), the lips are obligatorily oriented towards the

  high, because a lip pointing down would "return" when stuffing.

  According to a non-limiting option, the seal comprises a means for preventing the elongation during laying, such as a glass wire, an armed adhesive strip,

or the like.

  According to another embodiment paraffcular embodiment, the rigid portion 20 comprises substantially at mid-height a prolificance or "tail fir" 9 flexible, suitable and intended to cooperate with a groove or groove

  corresponding in the inner face of the frame 22.

  This last option was not represented; 1B. According to a first mode of realaffon, the rigid return 21 of the seal is adapted to apply tightly, over all (or substantially all) its length, against the upper 11 bevel of the frame (pareclose). Here "substantially" means that defects, irregularities, etc. can

  generate weak areas where the application is not tightly implemented.

  According to a second (preferred) embodiment, which is nonlimiting, the rigid return 21 of the joir is adapted to not be tightly applied against the upper face 11 of the bevel of the frame, leaving on the contrary a space 30 in the general form of << triangle >> (Figure 5) from its outer tip 40 and its junction with the top of the rigid portion 20 (which is also the inner end - that is to say towards the window) - of the bevel surface 11 of the frame According to another particular embodiment, (FIG. 6) the internal face of the rigid part z0 comprises, substantially at mid-height, a horizontal groove 22 intended to receive a strip of adhesive 24, for example preformed, of geometry adapted to allow said adhesive or sealant to seal

with the frame.

  Conversely, it will be possible to position one or more adhesive strips 24

  vertically or in any other geometric arrangement.

  This fine groove 22 is also normally used as a guide for the application of staples. _, _ r :: ::

MOD060202 8

  By "thinness" is meant here that this thickness should

  naturally not disturb the positioning of the "hat" (21, 5B).

  According to a nonh limiting option of the invention, the lower face 35 of the "return" portion 5B, 5C of the lip 5 is bonded to the upper face of the rigid return 21. Any assembly method forming a one-piece body will be well

heard acceptable.

  According to the best embodiment of the invention, the alpha angle formed by the general line of the upper profile of the lip 5 (5A and in particular 5B, 5C) with the horizontal is greater than 3 to 15, preferably 5 at 10, preferably about 5, at the angle beta formed by the profile of the bevel 11 of the

  frame 2 (pareclose) with the horizontal.

  According to the best exemplary embodiment, beta = 15 and alpha = 20.

  The choice of these values avoids the risk of detachment of the outer end of the rigid return 21 with the bevel 11, which would be unsightly and could cause upwelling capillary or, in case of

  serious detachment, by rising under the action of the wind for example.

  These angles are shown in the appended FIG. 6, which is not to scale.

  In FIG. 6, non-limiting options mentioned above, such as the thin adhesive strip 24 on the back, and the groove 22, have also been included.

zo agraphes.

  FIG. 6 shows again an internal groove 50 of the type

  22, capable of receiving a bead gasket 55.

  The material constituting the angle 20 with rigid return 21 will be chosen from rigid or semi-rigid plastics materials such as polypropylene7 PVC polyvinyl chloride (less fine material), and the like7 or aluminum metal profiles, made of stainless steel,

galvanized or not, and the like.

  The lips 5, 6, 7, 8 will consist of a usual flexible plastic material, that is to say selected from: elastomers - thermoplastic rubber SBR (styrene-butadiene) EPDM rubber optionally foam, preferably closed cells ,

and similar soft materials.

  As already mentioned, we can incorporate a glass wire anti

  o elongation, or other anti-elongation element as an armed band.

  It will also be possible to protect the lips 5 against paint by a skin

  delaminated, either glued or co-extruded, for example into elastomeric co-

  extruded with lips in another elastomer, this ensuring sufficient adhesion during installation and painting, and yet easy delamination then. According to a particular, non-limiting embodiment of the invention, the upper face 5 of the cap comprises a guide for the painter's brush, or "paint stopper", which consists of a protuberance 70 of rectangular or square section. or of similar shape, size and zo positioning adapted on the face 5 to correspond to the standard sizes of the pinccaux. This non-compulsory variant has been partially represented

  on the right side of Figure 4.

  The invention also relates to the method of manufacturing such seals which will be chosen in a known manner from extrusion processes, gluing,

  molding, and, most preferably, coextrusion.

  Those skilled in the art know these processes and it is not necessary to describe them. The invention also relates to the applications of the above joints, the nonlimiting list of which has been indicated above, as well as the "glazings".

equipped with such seals.

  The invention also covers all the embodiments and all the applications which will be directly accessible to the person skilled in the art of reading the present application, of his own knowledge, and

  possibly simple routine tests.
