Abstract

The invention relates to a window or a french window comprising a joinery frame surrounding two parallel end glass panes (4, 6) which are at a distance from each other and delimit an internal space divided into at least two intermediate spaces (10, 12) by at least one intermediate glass pane (6) arranged parallel to the end glass panes, air circulating in the successive intermediate spaces (10, 12) between a first orifice provided in the part of the joinery frame surrounding one of the end glass panes and a second orifice provided in the part of the joinery frame surrounding the other end glass pane. According to the invention, the joinery frame consists of a single frame (2), the intermediate glass pane (6) being immobile with respect to this frame, and in that the frame (2) comprises one or more access orifices (24A, 24B) to the intermediate spaces (10, 12) to permit cleaning of the faces of the window pane(s) delimiting the intermediate spaces.

Description

The present invention relates to windows, insulating French windows,

  subsequently designated by the single term of windows, comprising at least three parallel glazing defining at least two intermediate spaces, in which a flow of air circulates

  between the interior or exterior of the building (or in-

  installment) fitted with such a window.

  Such a window is commonly called "dynamic insulation" as opposed to windows with multiple glazing whose intermediate spaces are sealed and commonly called "static insulation". It turned out that compared to

  static insulation, dynamically insulated windows

  mique offer better thermal insulation and

acoustics and increased comfort.

  It should be noted that one of the difficulties

  countered in the realization of such a window is due to the fact that the circulation of air causes dust, particles or other solid matter in the intermediate spaces, this dust settling for example on the faces of the glazing It is therefore necessary to provide the possibility of cleaning the intermediate spaces and in particular the faces of the

glazing.

  In the case of a window with three panes,

  EP-A-0 027 581 solves the problem by providing

  creating a dynamically insulated window with the

  room consists of three 1 N parallel frames each supporting a glazing blocked in the frame with glazing beads Air passages are provided in the frames to guide the circulation of air in the intermediate spaces Two adjacent frames are joined on a vertical side by hinges so as to be able to pivot relative to each other in order to have access to the different

glazing faces.

  In EP-A-0 027 581, when the window has four panes, it can be seen that the space between the intermediate panes is sealed and therefore constitutes an air gap with static insulation,

  which limits the result obtained compared to a fe-

  be four-glazed with air circulation in

  all three successive intermediate spaces.

  The document EP-A-0 317 425 describes a window

  be dynamically insulated with three or four panes of glass, that is to say comprising at least two air spaces which

are all broken down.

  The joinery is composed of two frames hinged together using hinges and the intermediate glazing (s) are blocked between the frames on part of their periphery using

cleats for example.

  The intermediate glazings are articulated on the frame supporting the most extreme glazing

  close, along a vertical side so that

  see access, by pivoting the intermediate glazing,

  to each of its faces to be able to clean them.

  All windows comprising at least two ventilated air knobs, known at present, use the same principle, that is to say at least two frames hinged one on the other and intermediate panes hinged on the frames for

  3 N allow the cleaning of their faces.

  Such achievements are difficult to

  to implement, expensive and fragile to use.

  In addition, the various embodiments of this type, to have sufficient rigidity, include a carpentry, each side of the frames has a relatively large width, causing a significant heat exchange between the outside and the inside

  of the building through the carpentry.

  To remedy these drawbacks, the pre-

  sente invention aims to provide a window with dynamic insulation comprising at least two ventilated air spaces, separated by fixed glazing including

  the faces are easily accessible for cleaning

yees.

  Another object of the invention is to realize

  frames reducing the heat exchange between the interior

  the exterior of the building through the window

  series. 1 J 5 For this purpose, the invention relates to a window or French window comprising a carpentry surrounding two extreme parallel and spaced glazing defining an interior space divided into at least two

  intermediate spaces with at least one glazing

  2 medial LI arranged parallel to the extreme glazing, air circulating in the intermediate spaces

  successive between a first opening provided in the par-

  part of the joinery surrounding one of the extremely

  mes and a second opening provided in the part of the

  carpentry surrounding the other extreme glazing, characteristic

  characterized in that the joinery consists of a single frame, the intermediate glazing being fixed relative to this frame and in that the frame comprises a

  or several access holes to the intermediate spaces

  in res to allow cleaning of the faces of the

  glazing defining the intermediate spaces.

  On other features: the lower horizontal amount of a frame

  has an outlet for cleaning net products

  toyage; the discharge orifice is extended by a discharge pipe provided at its free end with said removable shutter to guide the products discharged during cleaning up to the rebate of the frame;

  the extreme glazings are fixed by collar

  lage on the uprights of the single frame; the uprights of the frame have vertical surfaces parallel to the glazing of reduced dimensions * 10; the extreme glazing located inside the building is an electrically heated glazing; accessories such as blinds, opaque films, lighting elements or the like are arranged in the intermediate spaces;

  when the passage between two spaces

  adjacent intermediaries consists of a space between the intermediate pane and the frame, the window includes a device for setting in motion and

  orientation of the air flow in the intermediate spaces

  diaries; the device for setting in motion and orienting the air flow comprises piping extending in said space along the upright of the associated frame, the piping comprising orifices

  forming nozzles aligned parallel to the plane of the vi-

  trages and regularly distributed, the piping being

  pivotally mounted between a first position in the

  which nozzles open into one of the inter-

  -0 adjacent mediaries and a second position in the-

  which nozzles open into the other inter-

  adjacent medium, the piping being supplied with air at high speed, means of rotation

  of the piping being arranged through the menuise-

  laughs. The invention will be better understood on reading

  of the detailed description which follows, given to

  by way of example, with reference to the accompanying drawings in which: Figure 1 is a schematic perspective view with partial cutaway, of a window according to the invention; Figure 2 is a partial sectional view

  according to line 2-2 of the window shown in Fig.

  gure 1; Figure 3 is a schematic sectional view of another embodiment of a window according to the invention; Figure 4 is a partial view in horizontal section of the window shown in Figure 3, showing the fixing of the opening on the frame; Figure 5 is a partial sectional view of the upper part of the window, showing a first embodiment of the air inlet and outlet openings; Figure 6 is a partial view in vertical section of the lower part of the window shown in Figure 3; * 2 m Figure 7 is a partial perspective view of a detail of Figure 6; Figure 8 is a vertical sectional view of the window shown in Figure 3, showing the arrangement of a device for setting in motion and orienting the flow of air in the intermediate blades; Figures 9 to 11 illustrate a pre-assembled glazing module and its arrangement in a frame

window.

  In Figure 1, there is shown schematically

  only a window opening comprising a single frame 2, that is to say composed of four uprights in one

  single piece surrounding three glazing 4, 6, 8 respectively

  demarcating an interior space divided in two

intermediate spaces 10, 12.

  Frame 2 has two horizontal uprights-

  rates 14, 16 and two vertical uprights 18 and 20.

  For example, in the horizon amount-

  * lower ri tal 14 of frame 2, there is an orifice

  air inlet 22 communicating with the intermediate space

  diary 10 so that an air flow flows in a

  ascending (arrow A) between glazing 4 and 6

  then descendingly (arrow B) between the vi-

  1 lines 6 and 8 to an outlet (not shown

  shown) opening onto the side of the upright 14 opposite to the inlet orifice 16 The orifices

  input can of course be provided in the

both upper horizontal.

  For this purpose, passages (not shown) which will be described later are provided in the

  upper horizontal upright 16 of frame 2.

  It should be noted that the passages can be

  formed by a space between the upright 16 and the vi-

  trage 6 which in this case is only fixed in the frame

on three sides.

  The vertical upright 18 is crossed by two holes 24 A and 24 B of rectangular section S ′ extending

  longitudinally in the direction of the length of the

  3 o both vertical 18 The holes 24 A and 24 B extend transversely on either side of the median plane of the glazing 6 to bring the outside of the window into communication with each of the intermediate spaces 10 and 12 The holes 24 A and 24 B are each sealed off by a removable plug 26, one of which

  only is shown in the open position.

  By removing the plug 26 from the associated hole 24 A or 24 B, it is possible to spray cleaning product on the faces of the glazing which are inaccessible when the plug 26 is in position, then to introduce into the interior spaces 10 and 12 a

  device for cleaning the faces of the glazing,

  presented in Figure 1 in the form of a squeegee 28 * i having two edges 30 bearing on the glazing 4 and 6, then actuating the squeegee 28 using a handle

  32 protruding outside the window.

  It should be noted that any set of cleaning

  yage may be used insofar as its di-

  mensions allow it to penetrate, through

  holes, in an intermediate space and to be ac-

  tionné. To allow the evacuation of the cleaning liquid used, an evacuation orifice 64 is provided (see Figure 6) opening inside each of the intermediate spaces and passing through the upright

  14 In the embodiment shown, this guide

  fice is sealed with a shutter

removable 66.

  As a variant, such an orifice can, for example,

  ple be extended by a flexible drain hose

  nor of said removable shutter When the window is open and the shutter is retracted, the end

  open pipe can be positioned in the foil

  r O lure of the window frame so as to evacuate the

  produced outside the building.

  It should be noted that the longitudi-

  nal and transverse holes, as well as the number of holes can be easily determined by those skilled in the art depending on the dimensions of the frame and the or

  of the cleaning devices envisaged.

  Although the holes 24 A and 24 B, in Figure 1, extend through the vertical post 18, it is evident that the holes necessary for cleaning

  can be drilled through any of the

  tants or across several amounts depending on the pos-

  access possibilities of the corresponding face of the

  amounts when the window is open.

  Indeed, in certain cases, in order to ensure sufficient rigidity of the uprights of the frame, it may

  it may be necessary to distribute the holes over two

  aunts. It is also possible to arrange the holes in such a way that each of them opens into

  a single intermediate space In this case, it is

  ident that the number and arrangement of the holes of-

  will be such that each intermediate space can

be cleaned.

  In Figure 2, there is shown a window according to the invention whose carpentry is metallic or

made of plastic.

  The carpentry has a frame and an or-

  vrant constituted by a single frame as before-

  indicated, i.e. each amount of which is

made in one piece.

  In Figure 2, there is shown in section the

  upright 18 of the window shown in Figure 1.

  The panes 4, 6 and 8 are fixed in the AO upright 18 using glazing beads, some of which are not shown, the section being taken along line 2-2 of FIG. 1, that is to say at through hole 24 B. In hole 24 B is inserted the plug 26 whose outer walls are in tight contact with the wall of hole 24 B. The plug 26 has a parallelepiped shape

  hollow, and it is made of relatively soft material

  ple, for example plastic or rubber. The plug 26 has an end wall

  42 which has a groove 44 in which is inserted

  fitted with a seal 46.

  When the plug 26 is inserted into the * O hole 24 B, the seal 46 comes into contact with the

  vertical edge of the glass 6 and provides sealing in

-be the cap and the glass 6.

  In Figure 3, there is shown schematically

  only in section a window according to the invention, in 1 S in which the glazing 4 and 8 are glued to the frame 2 The intermediate glazing 6 can be glued or held in position by a peripheral retaining seal. For this purpose, each amount of the framework, by

  example the amounts 18 and 20 shown on the Figu-

  re 3, have two parts protruding towards the inside of the window 48 and 50 on which

  the extreme panes 4 and 8 are supported.

  Windows 4, 6 and 8 are glued to the

  frame using beads of glue 52.

  In such an embodiment, using two glued panes, the panes participate so

  important to the rigidity of the whole.

  Consequently, such an embodiment makes it possible to reduce the dimension of the vertical faces 24 by

  each amount while ensuring sufficient rigidity

  you. The reduction in the dimensions of the faces 54, that is to say the width of the uprights, makes it possible to reduce the heat exchange between the interior and

  the exterior of the building through the uprights.

  In Figure 4, there is shown in section

  vertical an embodiment of the window

  shown in Figure 3, the carpentry being

  wood edging Note that the amount 18 is ar-

  ticulated on the frame 40 using hinges 56 which, given the small transverse dimension

  of the amount 18, are bolted through it.

  In Figure 5, there is shown an example of window whose carpentry is made of wood and in which the air intake holes in the intermediate blades are arranged in the upright

upper horizontal 16 of the frame.

  For this purpose, the amount 16 includes a pre-

  mier passage 58 connecting the interior of the building with the defined intermediate space 10

  through glazing 4 and 6, and a second passage 60 met-

  both in communication the intermediate space 12 deli-

  mite by glazing 6 and 8 with the outside of the frame

timent.

  Note that in this case, the glazing inter-

  middle 6 (see Figure 6) has a bottom edge

  horizontal 62 parallel to the upright 14 of the frame and is

  positioned relative to it, to constitute a pas-

  wise between the intermediate space 10 and the interior space

intermediate 12.

  In FIG. 6, it can also be seen that the intermediate spaces 10 and 12 communicate with Jo a discharge hole 64 passing through the upright 14 and provided with a removable shutter 66 constituted in the example represented by a plug closing so

seal hole 64.

  During cleaning, after having released the removable shutter 66, the end of the flexible hose which is permanently, or must be positioned, in the

  rebate of the frame 40 in such a way that the pro-

  intermediate evacuation spaces 10 and 12 are evacuated outside the building through an evacuation channel 68 provided in the usual way in

the frame 40.

  In Figure 7, there is shown an embodiment of the passage 58 or 60 made through the

amount 16.

  In this embodiment, the amount 16

  has near its end located inside the

  interior of teeth building 80 projecting towards

  the bottom and spaced apart from each other.

  The glazing 4 is bonded to the teeth 80, in

  leaving a space between the face of the upright 16 from

  shot from which the teeth 80 protrude.

  In this arrangement, the air passes between the space left free between the window 4 and said face

  of the amount 16 and passes between the teeth 80.

  Note that if you do not want the air to pass between the glass 4 and the upright 16, it is sufficient for the bead of glue to completely fill

  the space between the window 4 and the upright 16.

  In Figure 8, there is shown in section

  vertical window according to the invention, the mea-

  barnware is made of wood, and supports in the intermediate spaces various accessories such as

  an awning 82, or a night shading device.

  Note that in the embodiment shown, the intermediate window 6 is glued to the frame so that it leaves a space between

  the upright 14 and the lower edge of the glazing 6.

  The window shown in Figure 8 com-

  also carries a moving device

  orientation of the air flow which includes a pipe

  line 86 extending in said free space along the upright 14 of the frame under the lower edge of the glazing 6.

  The piping 84 has holes for-

  mant nozzles 88 aligned parallel to the plane of the glazing

  6 and evenly distributed over the length of the tu-

yachts 86.

  The piping 86 is pivotally mounted on the frame between a first position in which the nozzles open into the intermediate space 12 as shown in Figure 8, and a second position

  (not shown) in which the nozzles 88 open

  chent in the intermediate space 10.

  The orientation device includes mo-

  yen (not shown) for rotating the tu-

  yauterie between these two positions These means of rotation can be pull tabs or can be

electrically controlled.

  The device for orienting the air flow also comprises means for supplying the piping 86 with air at high speed to improve ventilation in the intermediate spaces 10 and

12.

  So in the example shown on the Fi-

  gure 8, the high speed air exiting through the nozzles

  88 will force ventilation in the inter-

  medials 10 and 12 in such a way that air will be 8 N taken through the passage 90 of the upright 16, will circulate in the intermediate space 10 then in

  the intermediate space 12 to emerge through the step-

  sage 92 provided in the upright 16 towards the interior of the building. In the case where the air flow must circulate in the intermediate spaces in the opposite direction, it will suffice to cause the tubing 86 to pivot so that the nozzles 88 open into the space 10. In the window shown in FIG. 8 ,

  the interior glazing, i.e. located towards the interior

  building, has an electrical resistance

  incorporated making, when powered, the

heating trage 8.

  This resistance can be inside a low-emissivity layer linked to the glazing or integrated

glazing.

  Such a provision further reduces the

  comfort due to the entry of air colder than the ambient temperature, as well as the effect of cold walls of the window Although already greatly reduced in a conventional dynamic window, the wall effect

  window completely disappears and the pro-

  the window becomes a very comfortable place.

  FIG. 9 shows a subset of

  ble or module 98 of glazing particularly suited to the implementation of the compliant window structure

* to the teachings of the invention.

  The glazing module here consists of three glazing 4, 6 and 8 which are arranged relative to each other in their relative positions

  that they occupy after mounting the module in the frame.

  This arrangement is ensured by an entourage of pre-as-

  semblance 100 of the type used for double-

  glazing with static insulation, but it was not born

  that the seal provided by the entourage 100

either as good quality.

  At locations corresponding to passages

  58 and 60 of the upright 16 and at the holes 24 A and 24 B of the

  while 18, the surround 100 of the glazing module comprises

  openings or cutouts, respectively 102, 104, 106 and 108, of corresponding dimensions which allow on the one hand the circulation of air between the glazings and, on the other hand access to the intermediate spaces by the holes 24 A and 24 B. To guide air through the frame from

  the interior or exterior of the building in the

  i.o sections 102 and 104 of the pre-assembled glazing module,

  an arrangement can be used as shown

  -shown schematically in Figure 10.

  Next to the cutouts 102 and 104, the frame is drilled and cut out over its entire thickness to allow the passage to two conduits 110 which are glued to the glazing module by cords 112 which ensure

  The frame is also drilled transversally

  Lement to allow passage to two other small conduits 112 which open and lean against two

  I side openings 116 of the conduits 110 The

  lines 114 are glued to the conduits 110 by strips of glue 118 The upper ends of the conduits

  114 are closed by stoppers 120 glued or screwed

  ses Hoods 122 arranged inside the frame

  are linked to the side faces of the frame and to the ends

  tees of the conduits 114 by gluing and / or screwing.

  The ducts and covers are illustrated schematically

  in perspective in Figure it.
