Definitions

  • the sliding leaf has at least one flange which is oriented at an oblique angle with respect to the plane of the leaf in the closed position;
  • The'flange is applied against a bearing surface of the opening which is oriented accordingly, said bearing surface being formed along the length of the flange and over at least part of the width of said flange.
  • the flange which is thus attached to the leaf has a contributory role in ensuring leak-tightness of the closure.
  • This invention relates to an opening of the type comprising at least one sliding leaf which can consist in par ticular of a panel of transparent or translucent material such as window-glass, plate-glass, or plastic material.
  • opening is used in a broad sense and must be understood to refer not only to windows or French windows but also to any openings which are fitted with guide members so as to permit sliding motion of leaves or panels.
  • This invention is more especially although not solely concerned with the case in which the opening is fitted with two associated leaves which are both formed of glass or the like.
  • the invention is directed to a particular arrangement of the opening and more especially of the sliding leaf which serves to ensure good leak-tightness and to overcome the above-mentioned disadvantages at least to a partial extent if not wholly.
  • the opening which i is fitted with a sliding leaf of transparent material is dis tinguished by the fact that said leaf has at least one flange which is orientedat an oblique angle with respect to the plane of the leaf in the closed position and that said flange is applied against a bearing surface of the opening which is oriented accordingly, said bearing surface being formed along the length of the flange and over at least part of the width of said flange.
  • the flange which is thus attached to the leaf has a contributory role in ensuring leak-tightness of the closure.
  • the flange of the leaf is integral with the remainder of said leaf and forms, for example, a dihedral angle of constant value with the plane of the leaf.
  • the invention advantageously provides for the flange of one of the leaves to come into contact with the flange of the other leaf in the closed position.
  • the flange of the leaf is joined to this latter by means of a flexible seal and especially a transparent and elastic seal which has a sealing rib.
  • Said seal can be shaped so that the flange should make a dihedral angle with the plane of the leaf in the rest position or on the contrary in order that the flange should be disposed substantially in the plane of the leaf in the rest position whilst the frame of the opening carries means for ensuring deflection of said flange in the closed position by virtue of the elastic deformation of the seal.

  • FIGS. 1 to 3 there is shown the application of the invention to the construction of a window having two leaves.
  • Said window comprises a wooden frame 1 composed of vertical uprights 2 and 3, ofa bottom cross-piece 4 and a top cross-piece 5 said frame 1 is fitted with two sliding leaves 6 and 7 of toughened glass (having a thickness of 6 mm, for example) so that in the present description, the words leaf" and pane will be considered as synonymous.
  • the leaves 6, 7 which are shown in the closed position of the glazed opening are slidably mounted in known manner in parallel grooves formed in the cross-pieces 4 and 5 of the frame.
  • grooves 8 and 9 there are formed in the bottom cross-piece 4 grooves 8 and 9 in which the panes 6 and 7 are adapted to slide respectively. Said grooves are fitted with seals (not shown) in a known manner.
  • Seals (not shown) in a known manner.
  • Verticalgrooves which are not illustrated and formed in the uprights 2 and 3 permit engagement of the edges of the panes which come opposite to said uprights in the closed position these grooves are also fitted with seals.
  • a handle 11 of known type serves to displace the glass pane 6 and to fasten this latter to the upright 2.
  • a catch 12 which is fixed on the glass pane 7 serves to lock said pane in position by fastening this latter to the upright 3.
  • the normal opening operation is carried out in a general manner in a movement of translation of the glass pane 6 towards the right-hand side the pane 7 can nevertheless be displaced for cleaning purposes, for example, after releasing the catch 12.
  • the panes 6 and 7 are provided with flanges respectively designated by the reference numerals l3 and 14 and oriented at an oblique angle with respect to the plane of the panes thus making a dihedral angle A with the planes of the glass panes.
  • Said flanges 13 and 14 are located on the side remote from the handle 11 and catch 12.
  • the flanges l3 and 14 have the same thickness as the leaves 6 and 7, this thickness being thus the same over the entire height of said leaves.
  • FIGS. 2 and 3 The structure of one of the glass panes such as the pane 6 as thus constituted can clearly be seen from FIGS. 2 and 3.
  • the flange 13 is integral with the pane 6, said flange having been formed by bending a preformed marginal strip in the hot state so that no optical discontinuity should exist between the pane 6 and the flange 13.
  • the bottom edge 15 of the pane 6 which is employed in the embodiment illustrated in FIG. 1 is adapted to slide on shoes which are placed in the bottom of the groove 8 in known manner.
  • the bottom edge 15 of the pane 6 which is in the sliding position within the groove 8 carries the weight of said pane.
  • the bottom edge 16 of the flange 13 is accordingly adapted to come level with the top face of the bottom cross-piece 4. This arrangement permits satisfactory leak-tightness between the flange 13 and the cross-piece 4.
  • Similar arrangements are made in the case of the top edge 16,, of the flange 13 of the pane, the distance between the edges 16 and 16,, of the flange 13 being substantially equal to the distance between the opposite faces of the crosspieces 4 and 5 of the frame 1.
  • notches 17 and 18 formed in the top edge of the pane 6. This arrangement is useful if, instead of sliding the bottom edge 15 within the groove 8, the pane 6 is suspended in known manner to carriages (not shown) which run on horizontal rails formed in the top cross-piece 5. Said notches 17 and 18 serve to secure the pane to said sliding carriages. Further recesses 19 are formed in the pane in order to fix closure and operating members (handle 11, for examp). The methods which are well known in the glassmaking industry for cutting, shaping (for bending the flange 13) and toughening glass sheets are applied to the fabrication of a leak in accordance with the invention.
  • the thickness of the glass panes which are normally employed for the fabrication of flat sliding leaves can be reduced by virtue of the fact that the folding of the flange 13 of the pane 6 endows this latter with a high degree of rigidity. This property is advantageous since the leaf is thus endowed with high bending strength, especially under the bending stresses produced by wind. Moreover, the reduction in thickness represents a very appreciable economic advantage.
  • the panes 6 and 7 in the closed position have flanges which are designated respectively by the reference numerals l3 and 14 and are of equal width (11 cm, for example), said flanges being adapted to, overlap in the closed position over a distance R of 8.5 cm, for example the axes XX and Y--Y of the grooves 9 and 8 are spaced at a distance of 30 mm, for example the flange 13 makes an angle A, of approximately 10 with the pane 6 and the flange 14 makes an angle A, of equal value with the pane 7. It has been found that, under these conditions, satisfactory leak-tightness is obtained when the flanges 13 and M are directly applied against each other. Leaktightness is even more satisfactory since, as has been mentioned in the foregoing, the rigidity of the panes ti and 7 is increased by bending their respective edge portions.
  • the flanges l3 and 14 of the panes 6,, and 7, are of unequal width their overlap is in this case equal to R which is smaller than R but the clearanceE between the edge 13,, and the pane 7,, is greater than in the previous example (e.g. 18 mm).
  • This arrangement is advantageous in order to prevent the flange 13,, of the pane 6,, which is displaced towards the right from striking the catch I2 which was already described with reference to FlG. ll.
  • the seals 21 and/or 22 can have a very small width or be formed of a transparent material such as silicone rubber. Thus, the visibility through the glazed opening is impaired only to a very slight extent, which is not the case with known devices at the present time.
  • a sealing device 23 which is interposed between the flanges 113 and M vertically in the axis of the window, said device being independent of the leaves and secured to the cross-pieces d and 5 of the frame ll.
  • said device 23 consists of a rigid sectional strip of extruded aluminum which is provided on its opposite faces with sealing brushes of polypropylene, said brushes being intended to come into contact with the opposite faces of the flanges l3 and M.
  • the device 23 is accordingly secured in a fixed position and in an oblique orientation with respect to the cross-pieces 4 and 5 of the frame 1.
  • the sealing device can also be flexible and consist of a spring surrounded by a tubular seal of neoprene or of a twisted metal wire of the tube-brush type in which soft bristles are incorporated. This device is stretched between the cross-pieces d and 5 of the frame l.
  • Said sealing devices 23 which can be of small size or partly transparent are similar to the previous embodiment in that they do not effect visibility through the glazed opening in any appreciable manner.
  • the invention can be generalized to the case of an opening which is fitted with more than two leaves.
  • the opening is provided with three leaves 27, 28, 29.
  • the central leaves such as the leaves 23 and 23,, which are slidably displaceable along the axis Y-Y each have two oppositely directed vertical bent edges or flanges I3, 113,.
  • the glass panes 29 and then 28 can be displaced towards the left to a position in which they are located opposite to the glass pane 2'7 the unit is then opened substantially to an extent of 3%.
  • the pane 23, can be displaced to a point opposite to the pane 27,, is of the unit is thus open in the central portion of this latter the pane 29, can then be displaced towards the left until it comes into contact with the displaced pane 2%,; Va of the unit is then open in the righthand portion of this latter.
  • angle A of the flange 13 of the pane 6 can advantageously assume values between 10 and 90, this latter case being illustrated by the flanges 13'', 14" of FIG. 12.
  • FIGS. 13 to 16 there will now be briefly described one embodiment of the invention which is of particular interest by reason of the excellent leaktightness with which glazed openings can be endowed by means of the corresponding leaves.
  • Openings fitted with flat sliding leaves are in fact known in which the leaves are subjected to an oblique downward displacement at the moment of closure of the opening, thereby ensuring a high standard of leaktightness between the bottom edges of the leaves and the bottom cross-piece of the frame.
  • FIGS. 13 to 16 The application of these arrangements to a leaf 6 in accordance with the invention is illustrated in particular in FIGS. 13 to 16.
  • the leaf6 comprising a flange 13 is suspended by means of rollers 33 and 34 which are pivotally mounted in fastening devices 31 and 32, said devices being attached to the pane 6 by means of notches l7 and 18, for example (as shown in FIG. 2).
  • Said rollers 33 and 34 are capable of displacement on parallel and horizontal rails 35 and 36 which are provided with inclined guide ramps 37 and 38, 39 and 40. Both the rails and ramps form an integral part of the structure of the top cross-piece 5 of the frame 1 and are known per se.
  • the pane 7 is supported by means of rails in the same manner as the pane 6 but that the inclined guide ramps 41, 42, and 43, 44 which are formed in said rails are directed downwards and towards the right these ramps cause the pane 7 to move downwards over a distance H while said pane continues its movement towards the right.
  • the opposite faces of the flanges 13 and 14 of the panes 6 and 7 are applied against each other under a constant pressure in the closed position this pressure develops under the action of the weights of the panes 6 and 7 which tend to separate these latter as long as the rollers to which they are suspended are engaged on the ramps of the rails.
  • enhanced leaktightness is obtained without any additional or manually operated clamping device.
  • the leaf comprises a flat pane 6, provided with an added flange 13,, also of plate glass.
  • the flange 13 is assembled elastically in this case by means of a seal 61 which is capable of being bonded to the glass such as a seal of silicone resin which is preferably transparent.
  • this assembly is so designed that, when no action is exerted on the glass pane and/or on the flange of this latter, a dihedral angle A is made between the plane of the glass pane and the flange of this latter (as shown in FIG. 18).
  • the seal 61 is preferably provided with a projecting rib 62 which is directed towards the exterior of the angle thus made.
  • the flange 13, is located in the rest position in the same plane as the glass pane 6,, and the seal 61, is accordingly designed so that, as a result of an external action G, said seal can be deformed elastically so that the flange 13,, should thus come to 13, thus making a dihedral angle A, with the plane of the glass pane 6
  • the seal 61 is advantageously provided with a projecting rib 62,,.
  • the leaves which are thus equipped can be associated with each other or with leaves of the type contemplated in FIG. 1 in a large number of possible arrangments, some of which will be given in detail hereinafter by way of example
  • a first arrangement shown in FIG. 20
  • two leaves 6,, 7 are associated, these leaves being provided with angular flanges 13,, 14, which are similar to those of FIG. 18 and form the same dihedral angle A
  • the ribs 62 of the seals 61 are applied against the opposite flanges, thus producing a double sealing barrier.
  • Steps can also be made to ensure that the angle of one of the dihedrons should have a value A, in the rest position which is greater than the angle A; as shown diagrammatically in FIG. 20.
  • leaves of the type shown in FIG. 19 in which the flange 13,, is in the rest position in the plane of the glass pane 6,, is provided with external components which ensure deformation of the elastic seal in the closed position.
  • This constructional design is shown in FIGS. 21 and 22.
  • the cross-pieces 4 and 5 of the frame 1 are provided in the vicinity of the central position with studs 71, 72 which serve to attach bladesprings 73, 74 terminating in rollers 75, 76 which are adapted to run along the edges of the leaves 6,, 7,, respectively and are applied against said edges under pressure by means of the blade-springs aforesaid.
  • the frame 77 of the opening has a bevelled edge 78 which ensures deflection of the flange 13,, when the leaf is displaced in the direction of the arrow F, with the result that effective leak-tightness can be ensured.
  • the invention is not limited to horizontally Sliding windows but can be carried into effect irrespective of the direction of sliding motion and is applicable, for example, to vertically sliding sash windows.
  • An opening comprising a frame fitted with two leaves made of glass at least one of which is-slidably mounted relative to said frame, each of said leaves having an integral flat vertical flange extending at an oblique angle to the plane of the rest of the leaf, said flanges being of glass, of one piece with their associated leaves, and applied against each other in the closed position.
  • each of said flanges is fitted with a seal.
  • An opening comprising a frame fitted with two leaves made of glass at least one of which is slidably mounted relative to said frame, each of said leaves having a vertical flange of glass secured thereto by means of a flexible seal, said flanges bearing against each other and extending at an angle not exceeding with respect to the extended plane of the leaves respectively in the closed position.
