Description

The present invention relates to window frames

  equipped with a glazing unit, capable of closing an opening

  ture of an exterior wall of a building, such as leaves

windows or doors.

  The ventilation of the premises of a building and more particularly forced mechanical ventilation, which, with the new insulation requirements, has become a common practice, requires the installation of vents

  that pass through the exterior walls.

  However, these vents, by means of which the fresh outside air is sucked in, cause significant energy consumption for heating by letting air inside the building. cold at a temperature much lower than that prevailing in the premises and

this especially in winter.

  We know a window pane with double glazing called "dynamic parieto", that is to say with active wall, which comprises a frame specially designed to allow air circulation from the outside to the inside of a building, this air circulating in the space between the

double glazing windows.

  Such a window sash arrangement effectively contributes to reducing the energy costs linked to heating and improves the thermal comfort of the premises of the building near the external walls insofar as the fresh air taken from the outside is previously heated to contact of the hot interior glass, thus avoiding cold drafts of ventilation. However, the manufacture of the chassis described above is complex

  and therefore results in a high production cost.

  In order to remedy the drawbacks of the prior art, the aim of the present invention is to provide a glazed frame, equipped with a glazing unit and means for the circulation of air from one face to the other of the frame,

  which is simple and inexpensive to produce.

  To this end, the invention relates to a glazed frame equipped with a glazing, capable of closing an opening of an exterior wall of a building, such as a window or door leaf, characterized in that the glazing window or second window is arranged on the face of the frame intended to be located on the outside of the wall or outside face, this second window being

spaced from the first.

  According to other essential characteristics of the invention: - The chassis comprises means for the circulation of

looks from one side to the other.

  - The means for the circulation of air comprise at least one air inlet orifice communicating with the space between the panes, formed on the external face at the level of at least one lower part of the frame and at

  minus one air outlet opening communicating with the

  space between the panes, formed on the inside

  at least at an upper part of the chassis.

  - The air intake opening is formed on the cross member

bottom of the chassis.

  - The air outlet hole is formed on the crosspiece

top of the chassis. -

  - Several shells spaced from each other are dis-

  laid in a rebate of the lower cross member, oriented towards the outside of the frame, and the lower transverse edge of the second window is applied to

  an approximately rigid strip fixed on a part of the external face

  lower of said shims so that at least a lower part of the intervals separating the latter is not

  not covered by the strip in order to spare, by these

  uncovered ties, common air intake ports

  having sex with the space between the panes.

  - According to a first alternative embodiment of 351'invention:

71090

  - The transverse edge. upper of the second window is supported in the vicinity of the outer peripheral edge of the outer face of the upper cross member of the chassis, being spaced from the latter and in that at least one orifice formed on the internal face of the upper cross member communicates with the space between

  windows in order to provide an air outlet opening.

  - The air outlet orifice crosses the upper crosspiece with regard to the second window and communicates with the space between the panes via the passage

  between the upper cross member and the second window.

  - In a second variant: - At least one air outlet orifice is provided on the inner face of the upper crosspiece which opens out

  in the space between the panes.

  The invention will be better understood on reading the

  description which follows, given only as

  example and made with reference to the accompanying drawing, in which: - fig.l is a sectional view along the height

  a closed window, the leaf of which is fitted with a frame

  sis according to the invention, with a sectional view of a block, and, - Fig.2 is a sectional view along the height of another embodiment of a closed window whose leaf is equipped with a chassis according to the invention,

with exterior view of a hold.

  The window structures which are the subject of the

  present description are wooden, but it is clear that

  the invention is not limited to this material and that it applies to any other material used in this field of technology, such as plastics and metals. The window shown in Figure 1 includes a leaf 1 hinged on a frame 2 in a manner known per se

710 90

  and is likely to close an opening in an exterior wall

  eur (not shown) of a building.

  The leaf 1 comprises a rectangular frame essentially formed by four elements two uprights 3, an upper cross 4 and a lower cross 5. Each of these elements of the frame is provided with a rebate which opens onto the face of the frame intended to

  be located on the outside of the wall or outside.

  Thus, the rebate 6 of the upper cross member 4 and the rebates 7 of the uprights 3 have a square profile, one surface 6a for the rebate 6, extends parallel to the plane of the leaf and the other, 6b for the

  rebate 6, extends perpendicular to this plane.

  The rebate 8 of the lower cross member 5 is,

  in this example, of the type known as "rapid drainage" and pre-

  feels a surface 8a parallel to the plane of leaf 1 and a

  surface 8b inclined towards the bottom of leaf 1.

  - .. According to the invention, several shims 9, ex-

  paced from each other, are arranged in the rebate

  8 of the lower crossmember 5, thus providing between each

  none of these a free interval 10.

  These wedges 9 punctually fill the rebate 8, seen in the direction of the length of the lower cross member and are each provided, facing the surface 8a of the rebate 8 which extends parallel to the plane of leaf 1, with a notch 11 which receives the lower transverse edge

first window 12.

  The other edges of the first window 12 take place in the rebates, respectively 6 and 7, of the

  upper crosspiece 4 and uprights 3.

  In addition, an air seal 13 is disposed between the face of the window 12 oriented towards the inner face of the leaf 1 and the surfaces of the rebates 6, 7 and 8 parallel to the plane of the leaf 1. On its face opposite, oriented towards the outside face of the frame, the first window 12 is held in the frame over the entire inner periphery of the latter on the one hand, by a first glazing bead 14 fixed on the surface 6b of the rebate 6 of the upper cross member 4 and second glazing beads 15 fixed on the surface of the rebates 7 of the uprights 3, parallel to the plane of the leaf 1 and on the other hand, by shoulders 16 which extend in height on the wedges 9, and form a edge of the notches 11. In

  in addition, a wedging pad 17 is inserted between the first

  first glazing bead 14, the second glazing bead 15 and the first

  window 12 and, wedging linings 18 of flexible material are inserted between each shoulder 16 of the shims 9 and

the window 12.

  An approximately rigid strip 19, for example made of metal, having a profile approximately in the shape of a Z and acting as a water jet, is fixed along the length of a branch 20 of the Z to the faces 21 of the shims 9, oriented towards the outer face of the leaf 1, the width of the branch 20 of the strip 19 being less than the height of the faces 21 of the shims 9 so as to provide, at the parts not covered with the free intervals 10, orifices air inlet 22 which are part of the means for air circulation, as will be described in

the following.

  Furthermore, and according to a characteristic es-

  sential of the invention, a second window 23 of sur-

  glazing is arranged on the outer face of leaf 1.

  A seal 24 is interposed between this second

  th window 23 and leaf 1, on the whole of the peri

  the spheres of the latter which is, moreover; articulated on an upright 3 of the chassis by its corresponding side,

  by means of hinges not shown.

  In addition, the lower transverse edge of this second window 23 is supported on the leaf 1 at the level

  of the branch. 20 of the strip 19 and its transverse edge su-

  is supported in the vicinity of the outer peripheral edge

  laughter of the outer face of the upper cross member 4, the other two edges of this second window 23 bearing on the corresponding upright 3 of the frame. Thus, the second window 23 is spaced from the frame by the seal 24, providing a passage 27 between the upper cross member 4, the glazing bead 14 and the second

window 23.

  Finally, several air outlet orifices 25 which are part of the means for air circulation,

  cross the upper crosspiece 4 opposite the two

  xth window 23 and communicate with space 26 included

  between the panes 12, 23 via the passage 27.

  Likewise, the air inlet orifices 22 communicate with

  the space 26 between the panes 12, 23 through the

  middle of the free intervals 10 between the holds 9.

  Thus, the leaf 1, in the closed position against the frame 2 as shown in Figure 1, allows air circulation from the outside to the inside of the wall by admitting, by suction, the air through the orifices input 22 (arrow A). This air then passes through the free intervals 10 and circulates in the space 26 comprised between the panes 12, 23 while heating up, if necessary, in contact with the first pan 12 adjacent to the interior of a building room. , to finally lead to the inner face of leaf 1 after circulation in the passage

  27 then into the outlet orifice 25 (arrow B).

  This chassis, according to the invention, meets the objec-

  tifs defined in the preamble insofar as it self-

  the passage of air from the outside to the inside of a building by circulation in the space between

  double glazing without requiring the manufacture of

  tion of a particular type of chassis.

  Indeed, the chassis proposed by the invention can very advantageously result from a simple and

  inexpensive of a conventional chassis.

  In addition, such a chassis provided with circulation means

  air provides an additional benefit by reducing

  tion of sounds coming from outside. This provides a

  strong acoustics not offered by conventional air vents which admit air following a path

  unfavorable to the damping of sounds.

  According to yet another advantage, the problem of fra-

  agility, linked to the spaced overlapping of two panes of glass on a frame which results in special precautions

  level of handling and packaging is simplified.

  In fact, in the arrangement according to the invention, the second window placed on the outside face of the frame is protected by the perimeter projection of the frame, thus making the handling and packaging conditions identical to those of windows fitted with insulating glazing prefabricated in factory. In the event of accidental breakage the cost of replacement is that of simple glazing and not that of expensive composite glazing.

  In an alternative embodiment of the invention, re-

  shown in Figure 2, the elements corresponding to those of the embodiment of Figure 1 have the same

  numerical references and the description will be limited to

  only parts of this embodiment that stand out

from that previously described.

  In this variant, the upper transverse edge of a second window 28 is supported in the vicinity of the inner peripheral edge of the outer face of the crosspiece

superior 4.

  Several air outlet ports 29 open directly into the space 26 between the panes 12, 28 and are each formed by a first bore 30 in part of the thickness of the upper cross member 4 and a second bore 31 inclined downward, formed partly in the upper cross member 4 and partly in the first glazing bead 14, which connects the space 26, comprised between the panes 12, 18, to the first bore 30 by opening-in the vicinity of the

bottom of the latter.

  In this case, the air which circulates between the panes 12,

  28 opens onto the inner side of leaf 1 after passing

  wise in the second hole 31 then in the first hole

slot 30 (arrow C).

  Such a chassis offers the advantage, compared to the first embodiment, of using a smaller surface

  for the second window while retaining the same qualities.
