Description

The present invention relates to a sliding window & sash

  horizontally. in a single plane whose interior and exterior frames are located in the same plane when the window & frame is closed and q u i is opened by sliding horizontally the

window's frame.

  Conventional windows and sashes sliding horizontally in a single plane have been described, for example, in the description of Japanese patent N '37194/1987. On this frame window, lower inner and outer guide rails are mounted in parallel on each other on a support part so as to be aligned in a direction perpendicular to the plane of the frame window. An outer frame is received by a lower roller which rolls along the outer lower guide rail. One end of a support member is pivotally supported on a lower roller which rolls along the lower inner guide rail, and the other end of the support member is pivotally supported on an inner frame to allow to the inner frame to be received by means of a lower roller which rolls along the guide rail

  lower through the support member. -

  In the conventional window frame described above, the weight of the interior frame and the exterior frame is loaded onto the support piece, so that the thickness of the window frame cannot be reduced to that of the frame

  window of a normal frame sliding horizontally.

  More specifically, the horizontally sliding sash window in one plane is a horizontally sliding sash window constructed to give the same appearance as a sash window when closed, and the function of the horizontally sliding sash window in only one plane increases when the thickness of the window frame decreases. However, in a

2 6 2648 174

  If the weight of the interior and exterior chassis is applied to the support piece, the support piece must be strong enough to support the weight. At least the thickness of the window frame must be large enough to distribute the weight of the interior and exterior frames. In addition, in the case of the conventional window with a sliding frame horizontally in a single plane described above, since the lower guide rail of the inner frame is mounted on the support piece parallel to the lower guide rail of the outer frame, the entire interior frame must be shifted inward when the window is open, which makes the opening operation difficult and prevents

  the use of a heavy interior chassis.

  An object of the present invention is to provide a window with a sliding frame horizontally in a single plane in which the weight of an outer frame is applied to a support piece while the weight of an inner frame is received by a cross member. high so that the entire weight of the window is distributed between the high cross member and the support piece and therefore makes it possible to reduce the thickness of the window frame. Another object of the present invention is to provide a window with a sliding frame horizontally in a single plane which can be opened without shifting towards the inside of the window.

entire interior chassis.

The upper auxiliary unit 42 is fixed to the upper cross member 1 by a screw 43 (FIGS. 20 and 21). The auxiliary unit 42 has a curved space 44, one end of which is aligned with the guide space 40 and the other end of which is located in an adjacent position with

  the external element 1a of the upper cross member 1.

  More specifically, the upper guide rail 33 is placed parallel to the upper guide portion 22 of the

  outer frame B on the inside of the latter.

  The guide space 40 between the upper guide rails 33 and 33 communicates with the curved space 44 formed in the auxiliary upper block 42. The chassis pulleys 34 and 35 move along the upper guide rails 33 and 33, the upper guide element 36 is engaged with the guide space 40 and the curved space 44

  and moves along spaces 40 and 44.

  The upper guide groove 37 is constructed with an inner element 2c of the support piece 2 and an intermediate element 2d located next to the inner element 2c, as shown in FIGS. 6, 11 and 20. The lower groove of guide 37 and the lower guide part 22 ′ of the outer frame B have the same position relation to each other as the upper guide rail 33 and the upper guide part 22, so that the lower guide groove 37 is placed on the inner face of the lower guide portion 22 'of the outer frame B and parallel to it. The central part of the intermediate element 2d which forms the lower guide groove 37, that is to say the part of the intermediate element 2d, in which the flap rail 10 of the outer frame B is aligned with the rail flap 32 of the inner frame B 'when the sash window is closed, is notched by forming a notch 46 in which a first roller 26a 174a of the lower guide element 38 on the flap side penetrates and leaves a groove 45 constituted by the intermediate element 2d of the support piece 2 and the guide rail 24 located on the outer face of the intermediate element 2d (Figures 6 and 11). As shown in FIG. 22, the end part of the intermediate element 2d and the end part of the guide rail 24, which are closer to the straight upright 3 ', are notched by forming a notch 41' in which is mounted a lower auxiliary unit 42 '. The lower auxiliary unit 42 'is located substantially below the upper auxiliary unit 42, and mounted on the support piece 2 by means of a screw 43'. A first end of a curved groove 47 formed in the lower auxiliary block 42 'is aligned with the lower guide groove 37, and an open end of the curved groove 47 which is at the opposite end is adjacent to a reception 2b of the support piece 2 provided on the outer face of the guide rail 24. The open end 47 ′ communicates with a drainage orifice 49 formed in the reception element 2b by a space 48 between the lower auxiliary block 42 'and

the receiving element 2b.

  The bottom flap guide member 38 and the bottom exterior guide member 39 move along a bottom guide groove 37. The bottom exterior guide member 39 is positioned to penetrate and leave the curved groove 47 which communicates with the lower guide grooves 37,

as shown in figure 22.

  The drainage orifice 49 communicates with the outside by a drainage orifice 50 formed at the end

  lower exterior of support piece 2 (Figure 22).

  The chassis pulley 34 on the flap side (FIGS. 7, 8 and 9) comprises rollers 34a which roll along an upper guide rail 33. The rollers 34a are supported

12 2648174

  pivoting on a main frame 52 by axes 51. An upper pulling roller 53 which also serves as a locking device is pivotally supported & a first end of the main frame 52 which is closer to the flap rail 32. The proximal end of a part 54 supporting the chassis is pivotally fixed to the intermediate part of the main frame 52 by means of a shaft 55. A spiral spring 56 is mounted between the shaft and the upper pulling roller 53 so & request a first retainer 57 in a direction where it is raised. A piece of the support 58 is suspended at one end of the main frame 52 which is closer to the upright 32 'through the guide space 40. A roller 59 is supported in rotation on the support piece 58. The roller 59 is in taken with a first curved groove 60 formed in the intermediate part of the chassis support part 54. A second retainer 62 is suspended from the part of the main frame 52 located between the support part 58 and the shaft 55 in a second groove curved 62 formed next to and on the face of the first groove

  curved 60 which is closer to the shaft 55.

  An assembly pin 63 is suspended from the front end of the chassis support element 54, and an intermediate frame in the form of a straight cylinder 64 is freely mounted on the assembly shaft 63. The intermediate frame 64 is mounted in a connection block 65. fixed to the upper rail 30 of the inner chassis B 'so as to be movable in the vertical direction, and the front end of an adjustment screw 66 which passes through the block

  link 65 is screwed into the intermediate block 64.

  In other words, the part of the inner chassis B 'which is closer to the flap 32 is supported by the chassis pulley 34 on the flap side.

  through the frame support member 54.

13 2648174

  When the frame window has to be closed, an upper end 57 ′ of the first retainer 57 is brought into contact with a protruding edge 67 formed on the central part of the upper cross member 1, that is to say provided immediately above of the guide space 40, and therefore falls in opposition to the biasing force of the spiral spring 56. When the frame window must be opened, the first retainer 57 is raised under the effect of the bias of the spiral spring 56. This brings a first lower end 57 "of this retainer in contact with the inner end surface of a proximal end 54 'of the frame support element 54, and therefore limits the pivoting of the element chassis support 54 around the shaft 55 in a first direction (pivoting anticlockwise while looking at FIG. 9). The pivoting of the chassis support element 54 in the opposite direction (clockwise when looking at FIG. 9) is limited by the contact of the second retainer 62 with a protuberance 68 formed on the outer end of the side wall of the second groove

curved 61.

  The space between the upper rail 30 of the inner chassis B 'and the upper cross member 1 is adjusted by acting on the adjustment screw 66. In FIG. 7, the

  reference number 69 designates a cover plate.

  The pulley of the outer chassis 35 is placed between the chassis pulley 34 on the flap side and the upper guide element 36 near the upper guide element 36. As shown in FIGS. 18 and 19, the chassis pulley exterior 35 includes rollers 35a which

  roll along the upper guide rail 33. The rollers-

  a are pivotally supported on. a main frame 71 via the shafts 70. The main frame 71 comprises parts in the form of arms 71 ′ and 71 ′ on

14 2 482648174

  which receiving rollers 72 are supported so as to be able to rotate in a direction perpendicular to the plane of the window. with chassis. A chassis support frame 73 is provided on the upper surface of the upper rail 30 of the interior chassis B '. The frame 73 chassis support has two opposite support parts

  73 'and 73' which are oriented towards the outside.

  The support pieces 73 'and 73' are received by the receiving rollers 72 and 72 'so as to be able to move in the direction perpendicular to the plane of the frame window. In other words, the part of the internal chassis B 'which is closer to the upright 32' is received by the external chassis pulley via the chassis support frame 73 so as to be able to move in a

  direction perpendicular to the plane of the sash window.

  As indicated in FIGS. 20 and 21, the upper guide element 36 comprises a piece in the shape of a tab 74, one proximal end of which is pivotally mounted on the external face of the internal frame B ', and rollers 36a and 36a are rotatably supported at the front end of the lug-shaped part 74. The movement of the upper part of the upright side 32 'of the inner frame B' between the uprights 3 and 3 'is limited by the movement of the rollers 36a and 36a. upper guide elements 36 along the guide space 40 and

of curved space 44.

  As indicated by. Figures 6, 10 and 11, the lower guide element 38 on the flap side has a mounting element 75 which is fixed to the flap rail 32 by means of screws 43 ". The mounting element 35 comprises a horizontal part 75 ' The proximal end of a leg-shaped piece 76 which is substantially bent at its center is pivotally supported on the horizontal element 75 ', and the first roller 38a as well as a second roller 38b will be supported in rotation on the front end of the leg-shaped part 76. The rollers 38a and 38b are engaged with the lower guide groove 37. The first roller 38a moves inside the groove 45 by means of the notch 46 and therefore allows the frame B and B 'to close the opening R when the frame window

is closed.

  Thus, the movement of the lower part of the flap side of the inner frame B 'is limited by the element

  guide on the flap side 38.

  A reference number 77 designates a receiving roller which receives the horizontal element 75 '. The receiving roller 77 is supported as a roll-up on the support piece 2 between a receiving element 2b and the guide rail 24. The outer lower guide element 39 is mainly represented in FIG. 22. The lower guide element outer 39 has the same configuration as the upper guide element 36, that is to say that the outer lower guide element 39 comprises a lug-shaped part 78 whose proximal end is pivotally supported on the upright 32 'of the inner frame B' and rollers 39a and 39a supported in rotation on the front end of the leg-shaped part 78. The rollers 39a and 39a are engaged with the lower guide groove 37. The lower part on the side of the upright 32 'of the inner frame B' is guided along the lower guide groove 37 and the curved groove 47 which communicates with the lower guide groove 37 at the

  means of the guide element on the outer side 39.

  The casement upright 32 of the inner frame B 'which is located on the horizontal part of the casement upright of the outer frame B when the sash window is closed has a slot 79 substantially at its center in the vertical direction. Slot 79 is closed by a

16 2648174

The upper and lower intermediate receiving elements 15 and 15 'which are brought into contact with the intermediate pulling rollers 91 and 91', are mounted on the inner surface 13c of the flap 10, like the spacing receiving elements 16 and 16 ', as indicated above. The intermediate pulling rollers 91 and 91 'are respectively compressed against the intermediate receiving elements 15 and 15'. As indicated above, the second central sealing material 14 which presses against the outer part 32b of the flap 32 of the inner frame B 'when the intermediate pulling rollers 91 and 91' are pressed against the intermediate receiving elements 15 and 15 ', is mounted on the first shoulder 13a of the flap 10 of the outer frame B

(figure 2).

  A first end of a flat upper spring 92 (Figure 7) is mounted on the upper part of the upper pulling element 88. An end of a lower flat spring 92 '(Figure 10) is mounted on the lower part d 'a lower draft element 88'. The other

18 2648174

  end of the flat upper spring 92 is mounted on the proximal end of an upper connecting piece 93, and the proximal end of a horizontally movable upper rod 94 is mounted on the front end of the upper connecting element 93 (figure 15). The upper rod 94 movable horizontally is engaged with a horizontal upper guide groove a whose wall on the outer side is formed by the outer member 30b of the upper rail of the inner frame 30 which is brought into contact with and separated from the second member d sealing 7, like the vertically movable upper rod 87 (since the vertically movable upper rod 87 is engaged with a vertical guide groove 95 provided on the flap 32) (Figures 7, 15 and 16). An intermediate upper draft element 96 is mounted at the front end of the upper rod 94 which is horizontally movable. As indicated in FIGS. 15 and 16, the upper intermediate pulling element 96 has a rising part 96a on its outer face. The intermediate part of the projecting part 96a is notched by forming a notch 98 through which a receiving element enters and leaves.

upper intermediate 97.

  The upper intermediate receiving element 97 is substantially suspended in the center of half of the upper cross member 1 which is closer to the straight upright 3 ′ and substantially located below the intermediate element

ld (figure 15).

  The other end of the lower flat spring 92 'is mounted on the proximal end of a lower connecting element - 93', and the proximal end of a horizontally movable lower rod 94 'is mounted on the element

lower link 93 '.

  The horizontally movable lower rod 94 'is engaged with a lower horizontal guide groove 95b

19 26? 48174

  whose outer side wall is formed by the outer part 31b of the lower rail 31 which is fine in contact with and separated from the second sealing material 7, just as the horizontally movable upper rod 94 is engaged with the horizontal upper guide groove 95a (Figures 10 and 15). A lower intermediate pulling element 96 ', is mounted at the front end of the movable lower rod

horizontally 94 '.

  The lower intermediate pulling element 96 'has substantially the same configuration as that of the upper intermediate pulling element 96, that is to say, that the lower intermediate pulling element 96' has on its outer face a hanging part 96 ′, as shown in FIGS. 15 and 17. The intermediate part of the hanging part 96 ′ a is notched by forming a notch 98 ′ by which an element enters and leaves

  lower receiving intermediate 97 '.

  The lower intermediate receiving element 97 'is mounted in a position which is symmetrical with respect to the upper intermediate receiving element 97 in the vertical direction, i.e. the lower intermediate receiving element 97' protrudes from the support piece 2 upwards near the receiving element 2b of the support piece 2 substantially in the middle between the right upright 3 ′ of the support piece 2 and the frame beating amount outside B which is in closed position

(figure 15).

  A support member 99 is provided on a surface 32e of the flap 32 of the inner chassis B 'which is placed opposite the flap 10 of the outer chassis B in the center in the vertical direction (Figures 12 and 14). The support element 99 comprises two horizontal parts 99a and 99a between which the proximal end of a limiting element 100 is engaged in order to

2648174

  allow the limiting element 100 to be supported on the horizontal parts 99a and 99a so as to be able to pivot

around an axis 101.

  The limiting element 100 includes a central portion 100a and upper and lower limiting portions b and 100b 'provided above and below the central portion 100a. A projecting portion 100 'is formed on the outer face of the central member 100a in the vertical direction. The front ends of the limiting pieces 100b and 100b 'are supported by the support element 99 so as to be able to pivot around the axis 101. The limiting element 100 is biased by a spiral spring 102 wound around the axis 101 in a clockwise direction when looking at FIG. 12, that is to say, in the direction in which the projecting part 100 ′ is spaced from the surface 32e, so as to allow the elements to limitation 100b and 100b 'to be placed on the trajectory of the vertical movement of the upper and lower intermediate elements 86 and 86'. An upper limiter receiving element 103 which is engaged with the upper limiting element 100b projects in the direction of the flap amount of the outer frame B at the lower end of the intermediate upper element 86, and a lower receiving element limiter 103 'which engages the lower limiter element 100b' protrudes from the upper end of the lower intermediate element

  86 'in the direction of the beat 10.

  As shown in Figure 2, roller frames 104 are suitably provided between the receiving elements 3b and 3b 'and ks interior elements 3C and 3c' of the left and right uprights 3 and 3 ', and pulling rollers auxiliary 104 which press against the roller frames 104 are pivotally mounted on the interior parts 10'c and 32'c of the uprights 10 'and 32' of the interior chassis and

outside B and B '.

21 2648174

  A handle 105 is mounted on the inner surface of the left upright 3 so that it can pivot in the direction of the right upright 3 '. An arm 106 which is formed & even the handle 105 is engaged with a groove 107 formed on the outer surface of the upright 10 'of the outer frame B when the frame window is closed. A pressure roller 108 is rotatably attached to the front end of the

arm 106 (Figures 28 and 29).

  The drainage opening 49 is covered with a tongue

109, as shown in Figure 22.

  The operation of the window components at

  chassis will now be explained.

  Figures 9, 11, 18, 20, 21, 22 and 27 show the frame window whose inner frame B 'is completely or partially open. At this time, as indicated by the broken line in FIGS. 12 and 14, the limiting element 100 pivots around the axis 101 in a clockwise direction when looking at FIG. 12 under the effect of the biasing force of the spiral spring 102. Therefore, the upper limiting element 100b of the limiting element 100 and the lower limiting element iOOb 'are respectively engaged with the upper receiving element of the limiter 103 and the lower reception of the receiver 103 ′, and an upward movement of the vertically movable upper rod 87 mounted on the upper reception element of the limiter 103 via the intermediate upper element 86 and the downward movement of the vertically movable lower rod 87 'mounted on the lower receiving element of the limiter 103' by means of the intermediate lower element 86 'are therefore prevented. In other words, although the upper and lower intermediate elements 86 and 86 'are connected to the pinion 83 via the upper and lower racks 84 and 84', the 2 2

22 '2648174

  limitation defined above prevents erroneous operation

of the control handle 81.

  At the same time, the lower end 57 ″ of the first stop 57 is engaged with the interior surface of the proximal end 54 ′ of the chassis support element 54 while the second stop 62 is engaged with the protrusion 68, and that pivoting of the frame support member 54 is thereby prevented. Consequently, the side of the inner frame B 'which is closest to the upright 32' is moved away from the outer frame pulley 35 by a fixed distance, same as the side of the inner frame B 'which is closer to the flap 32, and the pivoting of the arm 74 of the upper guide element 36, of the arm 76 of the lower guide element 38 on the flap side and of the arm 78 of the lower guide element

outside 39 is prevented.

  In this state, when the outer frame B along which the inner frame B 'must slide is pushed in the direction of the left upright 3, the outer frame B moves in the direction of the left upright 3 due to the rolling of the lower roller 23 along of the guide rail 24, and the internal element 10 ′ of the upright 10 comes into contact with the auxiliary pulling roller 104a provided on the left upright 3. Also, the spacing elements 27 and 27 ′ provided on the upper elements and exterior interiors 8a 'and 9a' come partially in alignment with the notches 29 and 29 'in a direction perpendicular to the plane of the frame window while the central draft elements 25 and 25' provided on the exterior elements 8a 'and 9a' partially align with the central receiving elements 26 and 26 'in a direction perpendicular to the plane of the sash window. This state, which occurs immediately before the sash window is closed, is shown on the

Figures 2, 4 and 23.

23 2 6 42 648 174

  When the internal frame B 'is moved in the direction of the right upright 3', that is to say when the internal frame B 'is moved to close the window with frame, when the position described above and shown in the figures 2, 4 and 23 has been reached or at the same time as the movement of the external chassis B towards the left upright 3, the rollers 34a of the pulley 34 of the chassis on the flap side and the rollers 35a of the pulley of the external chassis 35 are move along the upper guide rail 33 while the rollers 36a of the upper guide member 36 move first along the guide space 40 and then advance in the curved space 44. The rollers 38a and 38b on the flap side of the lower guide element 38 also move along the lower guide groove 37 (the first roller 38b reaching the notch 46, as shown in FIG. 11) while the rollers 39a of the lower guide element ieur exterior 39 first move along the lower guide groove 37 and then enter the curved groove 47, and the inner member 32'c of the upright 32 'comes into contact with the auxiliary pulling roller 104a, same as the inner element 10'c of the upright 10 of the outer frame B. This condition in which the inner frame B 'is in an inclined position relative to the window frame A is partially

  shown in Figures 9 and 11.

  At the same time, the upper end 57 'comes into contact with the projecting edge 67, and the first retainer 57 then descends opposing the biasing force of the spiral spring 56 and is released from the surface d 'inner end of the proximal end 54' of the chassis support member 54, whereby the chassis support frame 73, that is, the side of the inner chassis B 'which is closer to the upright 32 ′, is made movable in the direction of the pulley of the outer chassis 35,

24 2648174

  and the limitation of the movement of the arms 74, 76 and 78 is removed. Then, when the operating handle 81 is pressed to compress the flap amount 32 of the inner frame B 'outward, that is to say, towards the flap amount 10 of the outer frame B, the first roller 38a of the 'lower guide element 38 on the flap side passes through the notch 46 and enters the groove 45, and the upright 32' of the inner frame B 'is almost placed. between the auxiliary pulling roller 104a and the receiving element 3'b of the right upright 3 ', as well as the upright 10' of the outer frame B. Also, the projecting part 100 'comes into engagement with the inner end surface of the flap 10 of the outer frame B, by virtue of to which the limiting element 100 is pivoted in opposition to the biasing force of the spiral spring 102, by releasing the limitation of the upper and lower elements for receiving the limiters 103 and 103 ′ by means of the upper limiting elements and 100b and 100b ', and making the operating handle 81 functional. When the operating handle 81 is pivoted, the pinion 83 mounted on the rotating shaft 82 pivots, whereby the upper and lower racks 84 and 84 'are moved in the vertical direction. The - upward movement of the upper rack 84 causes the vertically movable upper rod 87 to rise through the upper intermediate element 86. This in turn raises the upper pulling element 88 fixed to the vertically mobile upper rod 87 and brings the upper spacing protuberance provided on the upper pulling element 88 in contact with the upper limiter receiving element 16. A downward movement of the lower rack 84 'descends the vertically movable lower rod 87' & through the intermediate element lower 86 '. This lowers

2648174

  then the lower pulling element 88 'connected to the vertically movable lower rod 87' and bring the lower spacing protrusion 90 'provided on the lower pulling element 88' in contact with the lower spacing receiving element 16 '. When the upper and lower spacing protrusions 90 and 'are respectively brought into contact with the upper and lower spacing receiving elements 16 and 16', the inner frame B 'and the outer frame B are respectively pressed against the right uprights and left 3 'and 3, and the uprights 10' and 32 'of the inner and outer chassis B and B' are thus interposed between the receiving elements 3b and 3b 'and the auxiliary roller 104, thanks to which the sides of the inner chassis and outside B and B 'which are closer to the uprights 10' and 32 'are pulled outwards. At the same time as these operations, the spacing elements 27 and 27 'of the upper and lower rails 8 and 9 of the outer frame B are brought into engagement with the notches 29 and 29', and the central draft elements 25 and 25 ' of the outer frame B are brought into alignment with the central receiving elements 26 and 26 'in a direction perpendicular to the plane of the frame window, whereby the central parts of the upper and lower rails 8 and 9 of the outer frame B are pulled outwards. Also, the flap rail 10 of the outer chassis B is also pulled outward when the upper and lower intermediate receiving elements 15 and 15 'are pressed against the upper intermediate pulling rollers and

  lower 91 and 91 ', as will be described later.

  Consequently, the entire outer frame B. is pulled outward towards the outer sealing material 12 placed on the outer elements 8a, 9a and lo0'a of the upper rail 8, the lower rail 9 and the upright 10 '' of the outer frame B, thus making contact with the

26 2648174

  first sealing material 5 while the first sealing materials 20 and 20 'provided at the upper and lower ends of the beat rail 10 come into contact with the upper and lower parts of the first sealing material 5 of the frame. Also, the external elements 8b, 8b and 10'b of the upper rail 8, the lower rail 9 and the upright 10 'come into contact with the second sealing material 7 while the second sealing materials 21 and 21' placed at the upper and lower ends of the flap 10 come into contact with the upper and lower frame parts of the second sealing material 7, thereby effecting a double sealing of the space between the outer frame B and the window frame A. When the upper pulling element 88 is lifted, the upper pulling element 89 mounted on the pulling element 88 comes into contact with the roller.

  top draft 53, as shown in Figures 5 and 7.

  When the lower pulling element 88 'is lowered, the lower pulling element 89' mounted on the pulling element 88 'comes into contact with the guide rail 24 provided on the support piece 2, as indicated on the figure, whereby the upper and lower parts of the flap rail 32 of the inner frame B 'are pulled outwards (while the part of the inner frame which is close to the upright 32' is pressed against the auxiliary pulling roller 104a and consequently drawn towards the receiving element 3'b of the upright amount 3 '). Also, the upper and lower intermediate pulling rollers 91 and 91 'provided on the vertically movable upper and lower rods 87 and 87' press respectively against the upper and lower intermediate receiving elements 15 and 15 'provided on the inner surface i 3 c of the beat rail 10 of the outer frame B,

27 2648174

  whereby the intermediate part of the flap rail

32 is pulled outward.

  When the upper pulling element 88 is lifted, the horizontally movable upper rod 94 is moved towards the upright 32 '(of the straight upright 3') by means of the flat upper spring 92 and the upper intermediate pulling element 96 mounted on the horizontally movable upper rod 94 is thus compressed against the external surface of the upper intermediate receiving element 97 displaced in the notch 98 and placed on the internal face of the riser 96a due to the displacement of the internal chassis B ' outwards. Also, when the lower pulling element 88 'is lowered, the horizontally movable lower rod 94' is moved towards the upright 32 'by means of the flat lower spring 92', and the intermediate lower pulling element 96 ' mounted on the horizontally movable lower rod 94 'is thus pressed against the outer surface of the lower intermediate receiving element 97' which moves in the notch 98 'and is moved on the inner face of the hanging part 96'a due to the movement of the inner chassis B 'outwards, whereby the intermediate parts of the upper and lower rails 30

  and 31 of the internal frame B 'are pulled outwards.

  As a result of the outward movement of the components as described above, the outer sealing material. 12 of the inner frame B 'comes into contact with the first central sealing material 18 provided on the outer element 10a of the flap rail 10 of the outer frame B, and the first sealing material 5 placed on the outer elements la and 2b of the upper cross member 1 and of the support piece 2 and on the external element 3'a of the upright 3 'come into contact with the external sealing material 12, as in the case of the

28 2648174

  outer frame B. In addition, as in the case of outer frame B, the outer elements j30b, 31b and 32'b of the upper rail 30, the lower rail 31 and the upright 32 'come into contact with the second sealing material. 7, and a double seal of the inner frame B 'in the same plane as for the space between the outer frame and the window frame A is thus obtained. The space between the flap rail 10 of the outer frame B and the flap rail 32 of the inner frame B 'is doubly hermetically sealed by the contact of the second central sealing material 14 with the outer element 32b of the upright of flap 32 of the internal chassis B 'and by the external sealing material 12 provided on the flap 32 of the internal chassis which comes into contact with

  the first central sealing material 18.

  When the opening R (window) must be opened, the components are returned to their original position by the operation of the operating handle 81 and the

  inner frame B 'is therefore moved inward.

  When the handle 105 is maneuvered, the arm 106 pivots, whereby the pressure roller 108 mounted on the arm 106 pushes the outer frame B towards the right upright 3 ', consequently, the spacer elements 27 and 27' are released notches 29 and 29 'and the opening operation

  of the external chassis B can be done regularly.
