Description

Process and seal with sealing lip in the direction of flow

inverted bure.

  The present invention essentially relates to a method and a seal with an inverted curvature sealing lip. More particularly, the invention relates to a method and a seal for sealing particularly in the center of a cross formed by four frames of carpentry, for example windows or

  of panels, including exterior building insulation.

  We know that in the building we are often faced with problems of tightness between frames of carpentry,

  windows or panels. We usually try to solve these problems

  Sealing problems through the use of a sealing lip gasket fixed by a foot in a receiving member of the frame, such as a groove or groove. The establishment of these

  joints is generally not easy. These seals can be found

  evenness on the outside of the frame or even on the inside, to reinforce the tightness, but at the level of the cross we have a stacking

  of four simple curved or non-curved lips creating a knot of

imperfectness.

  It has already been proposed in the prior art of using

  seal tubular seals. However, the tubular portions of these joints deform in the corners due to the angle of the frame, usually 90, which leads to the formation of a day or gap between the tubular portions of the joints. This day or this space is more important when we

  found at the cross formed by four frames.

  It has already been proposed by document FR-A-2 533 001 to

  solve this problem of tightness between the chassis, and in parti-

  at the cross formed by four frames by means of a tubular type seal having a substantially triangular and flattened cross-section, the narrow base of the triangle being from the foot of the seam seal having the seal presents two

  substantially flat faces at acute angle, this tubular joint

  both in the one-sided corners by deleting the other face in each of the four adjacent seams at the corners, so as to avoid excessive stacking of faces (to the total number of

  8) in the center of the cross defined at the angles.

  However, this solution has the disadvantage of not ensuring a seal in all circumstances because of the free space between the tubular portion of the seal and the single-lip portion; we find, in addition, the previous solution of the stacking of four Lips, generally flat, which does not solve

  not the technical problem of sealing at the cross.

  The present invention therefore aims to solve the

  new technical problem consisting of the provision of a solution

  to ensure sealing between adjacent carpentry frames, and in particular in the center of a cross formed by four frames of carpentry, avoiding the use of tubular joints through the use of seals single lip seal, low cost, while ensuring a perfect seal, especially at the level of

of said cross.

  The present invention further aims to solve the new technical problem above in an extremely

  simple, allowing easy assembly of carpentry frames.

  These technical problems are solved for the first time in a particularly simple, safe, inexpensive way,

  usable on an industrial scale.

  Thus, according to a first aspect, the present invention provides a method for sealing between adjacent carpentry frames, in particular at the center of a cross formed by

  four frames of carpentry, for example window or pan-

  in which a single lip current seal is used

  sealable around the perimeter of each frame,

  in that a lip seal is provided for

  curved core comprising a reversal of direction of curvature in the parts of the joint intended to be positioned substantially

  vertically in the vertical parts of the chassis of

  serie, said inn4t thus corp-ing a portion of vertical lip curved outwardly and a portion of vertical lip curved inward relative to the frame; each gasket is arranged on its associated chassis so that the lip portion curved outwards is above the lip portion

  curved inwards; and we put the chassis so

  to make a tiling of said curved lips, in particular in the area of the cross formed by four frames, thus obtaining a perfect seal especially at the level of the defined cross

between several chassis.

  According to a particularly advantageous characteristic of the method according to the invention, it is characterized in that it provides for the inversion of the direction of curvature of the sealing lip in

  a substantially median point of the vertical lip. This point

  median is generally substantially equivalent to a plan of

symmetry of the seal.

  According to a particularly advantageous embodiment of the process according to the invention, the direction of curvature of the sealing lip is inverted at an upper point of said lip. According to another variant embodiment, this inversion of the direction of curvature of the sealing lip is provided at a point

lower of said lip.

  According to another advantageous characteristic of the process according to the invention, the inversion of curvature of the lip is performed.

  by appropriate molding of the seal. A variant of reali-

  The invention consists in forming a joining of two half lips with an inverted direction of curvature by any appropriate means, such as gluing.

  or vulcanizing the edges of the two adjacent half-lips.

  According to another advantageous characteristic of the invention

  tion, the curvature of the sealing lip is such that during the tilting is performed a compression of the lips, which promotes

greatly sealing.

  According to another advantageous characteristic of the invention

  the horizontal lips of the joir have the same direction of curvature as the adjacent vertical lip part, which favors the

  tiling and obtaining a perfect seal.

  Naturally, the lip section of the seal

  Cheatia may vary depending on the existing game between the chassis.

  These lips may be made of vulcanized elastomer or

thermoplastic material.

  According to a second aspect, the present invention also relates to a seal providing a seal including

  in the center of a cross formed by four adjacent carpentry frames

  cent, including a single-sided sealing gasket

  table around the perimeter of each chassis with an integrated foot

  in a receiving member of the frame, such as a groove, characterized in that said sealing lip is a curved single lip comprising an inversion of direction of curvature in the joint parts intended to be positioned substantially

  vertically in the vertical parts of the chassis of

  serie, said seal thus comprising an upwardly curved vertical lip portion and an inwardly curved vertical lip portion relative to the frame; said outwardly curved lip portion being located above the portion of

lip curved inward.

  Thus, the eventual flow of water takes place in the channel defined by the curved lip portion outwardly

  located in the upper part of the seal and

  then follows on the curved lip portion inwards to be further guided in the channel defined by the lip portion

  curved outward of the next frame seal located

  below the chassis in question. Naturally, the embodiments or variants of this joint may be as defined

  previously related to the process.

  It is thus understood that this seal is simply

  a low cost of manufacture, easy assembly,

  usable on an industrial scale.

  Other goals, features and advantages of the invention

  will be made clear in the light of the explanatory description

  following diagram made with reference to the accompanying drawings

  several embodiments of a seal according to the invention, given merely by way of illustration and

  therefore can not in any way limit the scope of the invention.

  of a third embodiment of an inverted lip according to the invention.

  vention; FIG. 5 is a perspective view showing a

  seal according to the invention according to a first embodiment of

  1 and 2, as well as, in partial view, three adjacent adjacent frame seals in a spaced apart position so as to show how the curling will be performed; and - Figures 6 to 9 show sections along the trace line VI-VI; VII-VII, VIII-VIII and IX-IX, respectively, showing the respective positions of the sealing lips

after tiling.

  Referring more particularly to Figures 1 and 2, a seal according to the invention, represented by the general reference numeral 10, is a common gasket with a single lip seal 12 mountable on the periphery of a carpentry frame (Not shown) with a foot 14 insertable in a receiving member of the frame, such as a groove. This foot 14 may have various shapes adaptable to different grooves or grooves of

  chassis that may be on the market.

  According to the invention, the sealing lip 12 is a curved single lip comprising an inversion 16 of the direction of curvature

  in the parts of the joint 10 intended to be positioned sensitively

  vertically in the vertical parts of the carpentry frame.

  This seal thus comprises two vertical lips refer-

  12V1, 12V2 and two horizontal lips 12H1, 12H2,

  tively. In addition, each vertical lip 12V1, 12V2 is subdivided

  in practice in a portion of vertical lip curved outwards

  referenced 12V1A, 12V2A, respectively, and part of

  Inward curved vertical lip 12VIB, 12V2B, respectively

  relative to the chassis, in the mounted position, considering that the chassis comprises an interior edge directed inwardly of the building construction and an apparent outer edge of

  outside or in contact with the outside.

  According to the invention, the lip portion curved towards the

  12V1A, 12V2A, is disposed

  above the inwardly curved lip portion, namely the portion 12V1B, 12V2B. The portions of Lip 12V2A, 12V2B on either side of the inversion point 16 are clearly visible at

Figure 2 and Figure 5.

  According to an advantageous embodiment of the invention, the inversion point 16 of the direction of curvature of the vertical lip 12V1, 12V2 is disposed at a substantially median point of the vertical lip, according to the embodiment shown in FIGS. 2 and 5 to 9. However, according to an alternative embodiment (FIG. 3), the point of inversion 116 of the direction of curvature of the lip 112 is disposed at a lower point of the lip 112, that is to say that the

  dimension or the length of the lip portion 112V1A occupies practically

  the entire length or dimension of the lip 112, while the size or length of the inverted lip portion 112V1B is reduced or almost non-existent, as clearly visible

in Figure 3.

  According to another alternative embodiment shown in FIG. 4, the point of inversion 216 of the direction of curvature of the lip is disposed at an upper point of the lip 212. It will be observed that in this case it is on the contrary the upper part 212V1A of the vertical lip which is of extremely small size or length whereas the lower part of the vertical lip 212V1B occupies practically the entire dimension or the length of the lip

vertical 2! 2V1 or V2.

  In any case, it is preferred that the horizontal lips

  tales such as 12H1, 12H2 have the same direction of curvature as the adjacent vertical lip portion, such as 12V1A, 12V2A;

12V1B, 12V2B, respectively.

  According to a particular embodiment, the section of

  the lip may vary depending on the game between the chassis.

  This also applies to vertical lips 12V1, 12V2 and

horizontal lips 12H1, 12H2.

  These lips may be made of any suitable material

  required, in particular of vulcanized elastomer or thermoformed

  plastic. According to another advantageous characteristic of the seal according to the invention, the curvature of the lips 12V1, 12V2, 12H1, 12H2 is such that during the bending performed during the installation of the frames, especially When it comes to the frame of panel joinery of external insulation, the lips 12V1 are compressed,

12V2, 12H1, 12H2.

  According to a particularly advantageous characteristic, the curvature of the vertical lips 12V1, 12V2 is identical to the

  curvature of the horizontal lips 12H1, 12H2. However, according to

  In some variants, it is possible to provide different curvatures between the vertical lips 12V1, 12V2 and the horizontal lips 12H1, 12H2. It is the same for the dimensions of the lips themselves, to take account of the existing games between the frames, particularly in

  function of the desired aesthetic appearance on the external appearance

front of the facades.

  According to another particularly advantageous characteristic

  of the invention, the seal according to the invention is intended to be more particularly placed inside the

  chassis, that is to say towards the inner or rear edge, not

chassis.

  It can however also be used towards the edge

  exterior, front or apparent chassis.

  The seal according to the invention can be manufactured by any conventional method of manufacturing joints that is known to those skilled in the art. For example, it can be manufactured without problem, despite the point of inversion, by casting or molding, or by joining two half-lips such as 12V1A, 12V1B of the vertical lip 12V1, in the direction of reverse curvature, by

  all appropriate means of securing, such as bonding or vul-

  mechanization. However, the casting or casting technique is pre-

  because of its simplicity.

  It is thus understood that thanks to the seal according to

  the invention, all the technical advantages

  cements of simplicity, low manufacturing cost, rapid assembly, and perfect sealing, especially

  level of the cross defined between the angles of adjacent panels.

  This seal allows the implementation of the

  previously stated, and which is described in detail in

with Figures 5 to 9.

  This process, after having planned the joint as previously

  defined, comprises the step of arranging each gasket 10, 10 ', 10 "or 10"' on its associated chassis (not shown by simplification) such that the outwardly curved lip portion such as 12V1A, 12V2A is disposed above the inwardly curved lip portion, such as 12V1B, 12V2B. It is

  likewise adjacent joints 10 ', 10 "and 10"'.

  Then, we put the frames so as to realize a

  the curved lips. So, for example, the seal 10 has its

  vertical lip 12V2 which is positioned on the vertical lip

  wedge 12V1 of the seal 10 'so that the upper lip portion 12V2A is positioned on the upper lip portion 12V1A' and likewise for the lower lip portion 12V2B on the

  lower lip portion 12V1B '.

  In addition, the seal 10 "of the upper carpentry frame for example windows, or outer insulation panels has its lower horizontal lip 12H2", which should be noted that the direction of curvature, which is identical to that of the lower parts 12V1B and 12V2B of the vertical lips 12V1, 12V2, with a reverse direction of curvature relative to the upper horizontal lip 12H1 of the seal 10. The upper horizontal lip

  12H1 has a direction of curvature which is turned outwards, at the c: n-

  milking the lower horizontal lip 12H2 which has a direction of curvature turned inwards. In this way, the lip

  lower horizontal 12H2 "of the seal 10" is positioned

  above the upper horizontal lip.12H1 of the seal 10. There is

  after tiling, are clearly visible on the cuts of

Figures 6 to 9.

  It is thus understood that this tiling ensures a perfect seal and allows the infiltration or condensation water to flow in the vertical channels 12V1A, 12V2A or 12V1'A, 12V2A to then pass on the lower lip portions 12V1B, 12V2B before flowing into the mouths of the lips

  It is understood that various embodiments of the invention are possible. In particular, when the section of the lip is relatively large, it can be provided that the profile of the lip on the side of the foot of the seal is substantially rectilinear, while the profile of the lip has the aforementioned curvature of the lip.
