Description

i The present invention relates to a framing element at least

  partially made of wood for window, French window and the like, of the type whose faces exposed to the weather are protected by a waterproof cover, as well as to an article comprising such an element

  framing, in particular a window or door leaf

window.

  Frames for window and door

  window associated with protective casings, for example metallic, have already been known for a long time In particular, US patent 4122633 (HOLDIMAN) reports window frames and window frames whose uprights and crosspieces which constitute them are each associated to a metal sheet which covers over their entire length those of their faces which are intended to be exposed to the weather These cover sheets are held by flap and clipping of tabs on the sides of the rebates or of the grooved cheeks of said uprights and crosspieces windows mentioned in this patent US 4122633 are substantially supported, at each of their ends, on the longitudinal edges of the crosspieces with which they are associated A cover sheet which covers an upright at its rebate exposed to the weather is terminated, at each end of said upright, by a tongue head folded over the end edge of said rebate, this tongue being directly in contact with the part of the cover sheet which covers the groove cheek exposed to the weather of the crosspiece with which said upright forms

  an angle at this end.

  On a practical level, however, the production of window frames, French windows or the like

  overturning is not without difficulties.

  It is known in fact that a frame element for windows of the conventional type, that is to say without covering, is subjected to migration of water vapor between its interior faces, arranged on the interior side of the dwelling. on the walls of which said window has been integrated, and its external faces, disposed outside of said dwelling The partial water vapor pressure in a dwelling room is in fact generally much higher than the pressure of water vapor outside the house, this difference in water vapor pressure causing this migration through the wood of the window frames It

  should be noted, in this regard, that micro-

  porous protective with which the wood is usually coated window frames, have the essential function of preventing the penetration of water inside said wood, but do not stop moisture in the form of water vapor. However, when the wood of the windows is provided with a covering, the water vapor is trapped at the level of the said covering and it often happens that the wood of the framing element locally admits higher percentages of humidity. at the threshold of 18 to 20% beyond which said wood may deteriorate, in particular due to the condensation of water vapor and therefore permanent humidification

too important.

  The main object of the present invention is to overcome this major drawback and, to do this, proposes a casing framing element for window, French window or the like in which it is interposed, between the internal faces of said framing element which are intended to be arranged inside the house and the casing intended for its part to be exposed to bad weather, means for stopping or slowing down the migration of water vapor These means can be various and are for example constituted by recesses formed in the mass of said framing element and distributed over the entire periphery thereof They may also be constituted by aluminum sheets serving as vapor barrier and interposed between the internal faces of the element d '' frame and cover, the frame element then being made of laminated wood by assembling several pieces of wood one on the other

  with interposition of said vapor barrier aluminum sheets.

  Note that it has already been proposed in the patent FR-

  1422702 a window frame element, the faces of which are intended to be in contact with the protective cover, are provided with ventilation grooves extending around the entire periphery of said frame element However, this simple ventilation proves to be completely insufficient to be able to serve

  means of slowing down the water vapor.

  The recesses which the invention proposes to provide with a framing element, to serve as means for stopping or slowing down the migration of water vapor, pass through said framing element in its thickness, from its walls which delimit its internal framing contour to its walls which delimit its external framing contour, said walls being the walls which delimit said framing element transversely with respect to its external and internal faces, the internal framing contour (respectively being the one of the two contours thus defined which is the closest (respectively the farthest) to the framed element These recesses allow the

  water vapor to escape from the wood of the frame element.

  In particular, in the case where such a recess opens out of said framing element on the outside of the latter, the vapor pressure inside said recess is equal to the vapor pressure outside of the element. frame, so that the water vapor is evacuated directly by said recess since no differential pressure exists between said recess and the cowling

of the framing element.

  In addition, these recesses distributed around the entire periphery of the framing element also have another major advantage, since they make it possible to treat the wood (for example against fungi, insects, etc.) not only superficially at the level of the faces of the framing element and of its walls which delimit its internal and external contours, but also at heart When, in fact, the framing element in the autoclave is subjected to a conventional treatment, for example fungicide and insecticide, the wood of the framing element will be treated to the core at the level of said recesses The framing element will therefore have better resistance over time than the framing elements

of classic type.

  In a particular embodiment of framing elements for window or French window sashes, the recesses serving as a means of stopping or slowing down the water vapor extend in the mass of said bottom framing element from the groove thereof intended to receive glazing or a wooden panel associated with said leaf, up to a wall delimiting the external contour of said framing element, on the external side thereof The bottom of this groove or this panel is therefore in contact

  permanent with the outside of the window or door

  window, which gives said glazing or panel more

great health and durability.

  It is also important to note that the recesses which the invention proposes to provide with the hooded framing elements for windows, French windows or the like, are not directly visible, since they do not emerge from said framing element, nor at its internal faces, nor at its external faces A framing element according to the invention is therefore just as aesthetic as the known casing framing elements

until now.

  Incidentally, in another of its aspects, the invention proposes a casing of framing elements of a much better seal than the casings of the prior art and, in particular that the casings presented in patent US-412233 , the cowling of the invention being substantially of the same type as that of this patent US-4122633 and comprising interposed between an end tab and the part of the cowling sheet which covers a groove cheek exposed to the weather, directly opposite , a

seal.

  In addition, the invention also provides, in the context of French window wooden panels, a framing element associated with a seal which provides, over its entire periphery, the seal between its framing groove and said panel. made of wood, said joint having the advantage of not being visible once the assembly of the wooden panel / framing element has been carried out and of being a non-sticky joint, allowing, consequently, the disassembly of said framing element, by example for the possible replacement of a broken glass or a deteriorated part of the French window which

  associated with said framing element.

  The present invention therefore relates to a framing element at least partially in wood, for window, French window or the like, intended to be exposed by one of its sides to the weather and the other side of which is intended to be disposed at the interior of a dwelling, its external faces intended to be exposed to the weather being covered with a cover made of a waterproof material, this framing element being characterized in that it comprises, distributed over its entire periphery, means for stopping or slowing down the migration of water vapor, interposed between said cowling and its faces intended to be arranged inside

  of said dwelling, or interior faces.

  Advantageously, means for stopping or slowing down the migration of water vapor comprise recesses which pass through said framing element in its thickness from its walls which delimit its internal framing contour to walls which delimit its external framing contour, said walls being the walls which delimit said framing element transversely with respect to its external and internal faces A recess of this type preferably opens at one of its ends, on the external side

said framing element.

  Preferably, in the case where the walls delimiting the internal contour of said framing element are provided with a framing groove, a recess serving as a means of stopping or slowing down the migration of the water value extends from the bottom of said groove to the walls delimiting the external contour of said framing element. Such a recess can advantageously be a mortise or be substantially cylindrical. In the case where the framing element is provided with a framing groove, intended to receive the framed element, such a mortise extends obliquely from the bottom of said groove to the walls delimiting the external contour of said framing element, to open from said walls towards the casing thereof, a hole s extending from the bottom of said grooves substantially parallel to the main plane of the framing element, and substantially perpendicular to the

  contours of the frame element.

  In another preferred embodiment, means for stopping or slowing down the migration of water vapor comprise a vapor barrier sheet made of a material which is impermeable to water vapor. This vapor barrier sheet may for example be a sheet aluminum, the frame element

being with laminated wood support.

  In yet another advantageous variant, means for stopping or slowing down the migration of water vapor comprise a sealed profile with grooves interposed between said cowling and the faces of said framing element intended to be exposed to the weather. can

  be in particular of a plastic material.

  In the case where the framing element comprises two uprights associated with two crosspieces, the means for slowing down or stopping the migration of the water vapor which is provided with the low crosspiece are advantageously constituted by mortises which pass through it in its thickness. More preferably, the recesses serving as means for slowing down or stopping the migration of the vapor.

  of water are distributed over more than 30% of its periphery.

  Advantageously also, the framing element comprises crosspieces and uprights assembled together at an angle, a crosspiece being supported on an upright at each of its ends, each upright and crosspiece being associated with a cover sheet which it is secured to it by clipping, a cover sheet associated with a cross member comprising at each of its ends a tongue folded over one of the end edges of said cross member and conforming to the shape of the cover sheet of the upright with which it is associated at the level from this end, with interposition of a seal between said

sheets and rollover.

  The invention also relates to a window sash

  or French window with such a framing element.

  Very advantageously, a window door leaf of this type comprises a framing element associated with a wooden panel provided with a seal embedded mainly in a recess formed in the thickness of said wooden panel and a portion of which projecting from said recess is interposed in the lower flank of a rebate of said

  framing element and said wooden panel.

  The following descriptions of several modes of

  embodiment of the invention are purely illustrative and not limiting. They must be read with reference to the appended drawings, in which: FIG. 1 is a front view of a leaf angle

  Figure 4 is a top view with cutaway of an upright or a cross member of a window sash frame element according to another embodiment of the invention. Figure 5 is a sectional view along the line V-V of

Figure 4.

  Figure 6 is a sectional view similar to that of Figures 3 and 5 of a window sash comprising a framing element according to another embodiment of the invention. Figure 7 is a sectional view similar to that of Figure 5 of a window sash with a framing element according to yet another embodiment of the invention; and Figure 8, finally, is a sectional view of a detail of a French window with wooden panels associated with an element

  framing according to the invention.

  The window sash shown in Figures 1 to 3 essentially comprises a framing support 1 associated with a glass V and consisting of two uprights 2 and two crosspieces 3 assembled together, for example mechanically as described in the application of patent of the applicant filed under NO FR-8910687, the crosspieces 3 abutting against the uprights 2, the upright 2 and the crosspiece 3 shown in Figure 1 together forming a right angle, referenced by A. The support frame 1 is provided on its inner periphery with a continuous groove 4 in which is housed said glazing V This groove is delimited on each upright 2 and passes through 3 by the sides of two cheeks of groove 5 and 6 facing the cheek of groove 5 is intended to be disposed, once the entire leaf is in place in its frame, on the side of the window which is outside the house and which is therefore exposed to the weather ries, the groove cheek 6 being intended to be disposed on the inside of the window This groove cheek 6 is extended on the side of the leaf opposite to the glazing V by an abutment rebate 7 having substantially the same thickness and intended for come to bear, by its substantially flat face forming a heel directed towards the outside of the window, on a complementary wall of the frame of the

leaf 1.

  The cross member 3 is terminated at its end in abutment on the upright 2 by a projecting tab 7 a, extending the central part of said cross member 3 which is located between the cheeks of groove 5 and 6, this tab 7 a being intended to s recess in a complementary manner in the groove 4, at the said angle A, a seal 8 being interposed at the level of this tab 7 a between the crosspiece 3 and the upright 2 This seal 8 has a shape substantially U with extended edges, and follows the shape of groove 4 and

groove cheeks 5 and 6.

  The faces of the frame 1 which are intended to be exposed to the weather are coated with a cover 9 having both protective and decorative functions. Each cross member 3 and amount 2 is associated for this purpose with a sheet.

  in profiled aluminum, respectively referenced by 10 and 11.

  These sheets 10 and ll each extend respectively over the entire length of the upright 3 or the cross member 2 with which they are associated by clipping, on the one hand, to a projecting edge 12 which is provided with the frame 1 on its entire outer framing periphery at the level of the overlapping rebate 16, which is the wall which delimits, with the heel 7, the external contour of the framing element 1 and, on the other hand, on the grooved cheeks 5 The sheet 10 associated with the cross 3 ends at each of its ends by which said cross is in abutment on the uprights 2, by a tongue 13 folding over the skirt 14 which substantially extends the face of the cross 3 is exposed to the weather and which is intended, once said cross member 3 assembled on an upright 2 at this end, to laterally border the groove cheek 5 of said upright 2 Between this skirt 14 and the groove cheek 5 are interposed the nguette 13, one edge of the seal 8 and the part of the cover sheet 11 which covers said groove cheek, the edge 8 itself being interposed between said tongue 13 and said part of sheet ll which covers the groove cheek 5 , thus achieving a perfect seal between the

different sheets of the cowling.

  The framing element 1 is associated with means 15 intended to slow down and even stop the migration of steam

  of water between its interior and exterior faces.

  These means 15 comprise, for example, mortises 18 which are formed in the mass of said cross member 3 between the face of said cross member which is intended to be disposed inside the dwelling and the cowling 9, extending across the bottom of groove 4 to the rebate of

  cover 16, towards the edge 12 of clipping of the cowling 9.

  il Means 15 according to another variant, have been shown in Figures 4 and 5 They consist of cylindrical holes 19 regularly distributed in the thickness of the framing element 1, these cylindrical holes 19 extending substantially radially with respect to the periphery of said framing element, parallel to the plane of glazing V, from the bottom of the groove 4 to the face of framing element 1 which delimits its outer framing contour and which is intended to be facing, when the window sash is in position

  closed, doorframe wood associated with said leaf.

  All these means 15 are equivalent and can be

  installed either on uprights or on crosspieces.

  Preferably, however, the lower cross members of the mortise leaves will be fitted in order to ensure good evacuation of the water. Very good results are obtained with recesses of this type distributed over 30 to 60% of the periphery of the element. framing and for example with mortises of 5

  mm thick or with 9 mm diameter holes between

21 or 50 mm axes.

  Another embodiment of the invention has also been shown in FIG. 6: the means 15 for slowing down the water vapor essentially comprise, in this variant, a sheet 20 of a waterproof material interposed between the cowling 9 and the face of the framing element which is intended to be disposed on the interior side of the dwelling This waterproof sheet 20 serves as a vapor barrier and is for example made of a metallic material (aluminum foil), the element of framing 1 then being a laminated wood framing element It should be noted that these laminated wood framing elements have good mechanical strength as good as the conventional framing elements. Another possible variant has been shown in FIG. 7 In this variant, it is interposed, between the cowling 9 and the external face of the wooden part of the framing element, which is directly opposite this cowling, a profile 21 with groove 22, which is for example made of PVC The grooves 22 of this profile 21 are directly in contact with the external faces of the wooden part of the framing element, the bottom 23 of the profile 21 carrying said grooves, being in contact with the

cowling 9.

  The invention has been described here in the context of a window sash; it however applies, of course, to all types of window, French window or similar framing, and in particular also to window frames,

  furs, mullions, support sleepers.

  There is shown in Figure 8, a detail of carrier

  window according to the invention in which the framing element 30 is associated with a wooden panel 31 mounted in the groove 4 of said framing element 30 This framing element is provided with means 15 for stopping or slowing down migration of water vapor, which are for example mortises 18 extending from the bottom of the groove 4 to the covering cheek 16, towards the clipping edge

12 of the casing 9.

  Advantageously, this wooden panel is associated with a seal 33 whose main body is housed in a recess 32 formed in the thickness of the wooden panel 31 opposite the bottom of the groove 4 of the framing element. 30, this joint comprising a main tongue 34 which is interposed between the wooden panel 31 and the inner flank of the rebate 35 which is that of the two rebates of the framing element which is on the inner side of the dwelling. The reference signs inserted after the technical characteristics mentioned in the

  claims are intended only to facilitate the

  understanding of them, and in no way limit their scope.
