Definitions

  • the present invention relates to the field of operable windows, generally for buildings.
  • operable windows are designed as an assembly of three elements, a glass, a mobile frame supporting the glass, called together sash, and a fixed frame fixed to a building structure.
  • These elements have to satisfy structural requirements, like supporting glass weight and wind loads by the mobile and fixed frames and to transfer them to the building structure.
  • structural requirements like supporting glass weight and wind loads by the mobile and fixed frames and to transfer them to the building structure.
  • it is common practice to use frames with big transverse sections which need to be clearly even bigger when the window pane has large dimensions and in this manner entails higher wind loads and own weight.
  • the windows should also be designed to reduce thermal bridges, i.e. the places where a large quantity of heat transmission occurs.
  • the most disadvantageous part of the window structure is the frame which, especially when made of metal, has a higher conductivity index than the glass and thus, to reduce thermal transmission, the glass to frame surface ratio should be maximized as much as possible.
  • a window frame which, according to claim 1 , comprises a primary frame, adapted to be fixed to a building structure, a secondary frame fixed to the primary frame by ironmongery allowing opening and closing movements of the secondary frame in respect of the primary frame, wherein a plane of the window frame is defined when the secondary frame is closed, wherein the primary frame comprises at least four primary profiles, each of the at least four primary profiles comprising a primary first profiled bar having a primary parallel side having a first height w1 when measured parallely to the plane of the window frame and of the glass pane, and a primary orthogonal side, a primary second profiled bar fixed transversely to the primary first profiled bar on an outermost perimeter of the window frame and wherein the secondary frame comprises at least four secondary profiles, each of the at least four secondary profiles comprising a secondary first profiled bar having a secondary parallel side

  • the window of the invention is definitely an increased thermal insulation.
  • the window according to the fact that the glass thermal conductivity index is lower than the thermal conductivity of aluminum or of other metals, the window has a superior global insulating capacity, because the frame dimensions, which are mainly of aluminum, are reduced at a minimum, which is achieved thanks to the slender frame, when observed in a front view.
  • This feature gives also the impression to look“through” a window instead of looking“at” a window, because the glass area of the window is maximized and has no interruptions, while the frame surface is minimized and without any disturbance caused by visual joints, hairlines, groves, steps or the like and keeps the same width“w” for all window frame thicknesses.
  • the window of the invention provides a good-looking window with a maximum of thermal insulation capacity.

  • the glass pane 3 in order to meet market or legislative standards on thermal or acoustic insulation performance, can be made with a multi-layered glass with internal chamber(s) or even opaque panels.
  • the fixed frame 1 has basically a rectangular or square shape, although other shapes are possible, without going out of the scope of the invention, and comprises four primary profiles 21 , 22, 23, 24 which define the window’s perimeter.
  • the sash frame 2 is made of four secondary straight profiles 31 , 32, 33, 34, arranged in a rectangular or square shape too.
  • the primary profile 21 comprises a primary first profiled bar 4, made preferably of aluminum or of another metal or alloy, a primary second profiled bar 5 made of composite material, with low thermal conductivity, e.g. polyamide and primary gaskets 6, 7.
  • the primary first profiled bar 4 has a substantially C-shaped section with a longer side parallel to the window plane and three aluminum flanges 10, 11 and 12.
  • the flange 10, which is orthogonal to the plane of the window frame comprises the open channel 25 located at the end of the profile proximal to the center of the window frame 100 and directed transversely to the profiled bar towards the internal side I of the window frame.
  • the primary fixed profile is supposed to be on the external side E of the building in which the window is installed and therefore the sash is opening towards the internal side I of the building. It is possible to reverse the external and the internal side of the window in order to apply the window with an outward opening sash, whilst keeping all profiled bars and components the same, except using the appropriate ironmongery.
  • this is achieved thanks to the selection of appropriate length d2 of the flange 10 as explained below.
  • Two flanges 11 , 12, are located at the distal end of the primary profile 21. These two flanges are straight and parallel and directed substantially transversely to the primary first profiled bar 4. They are provided with two ribbed surfaces 13, 14.
  • the flange 11 is empty and defines a hollow cavity.
  • the primary first profiled bar 4 has also a flange 9 which, with the flange 10, defines the longitudinal channel.
  • the primary second profiled bar 5 is a profile with 2 hollow cavities with, at one side, two primary composite flanges 15, 16 which are parallel and each one has its own composite ribbed surface, respectively 17, 18.

  • the fixed frame 1 has also two gaskets 6, 7 which seal the gaps between the fixed frame 1 and sash frame 2 when the sash frame 2 is closed on the fixed frame 1.
  • the first gasket 6 has a cross section wide and thin with a rounded extrusion 19 that is empty inside to fix it into the channel 25.
  • the second gasket 7, has a substantially square cross section and is empty inside, with the rounded extrusion 20 that is empty inside to fix it into the channel 26.
  • the gaskets 6, 7 which function as seals between the internal space of a building and the external open space, when the sash frame 2 is closed, are subject to sufficient pressure on their contact surface to prevent the passage of too much air and water between the gaps that exist between the fixed frame 1 and the sash frame 2.
  • the shape of the gaskets 6, 7 also allows the necessary water drainage from the internal of the window frame to the outside and gasket 7 creates a mid-seal between fixed frame 1 and sash frame 2 as is appropriate in operable window technology.
  • the fixed frame 1 has a square or a rectangular shape composed by the four mitered primary profiles 21 , 22, 23, 24 as sides, at each comer it is connected by three comer-cleats 51 , 52, 53, shown in Fig.
  • the three corner-cleats 51, 52, 53 are made of metal, preferably, and have the function of corner connectors fixing solidarily the primary profile 21 to the primary profile 22 to make the fixed frame 1 a solid structure that enables to connect the window frame 100 solidarily to the building structure.
  • Loads imposed on the comers of the primary frame and the sash frame resulting from opening the sash, from the weight of the frames and the glass and from the wind loads are accommodated by the corner cleats and transferred to the building structure over the hinges or hinge system being part of standard ironmongery connecting the fixed frame 1 to the sash frame 2 and the corner brackets of the fixed frame.
  • the three corner cleats 51 , 52, 53 are all L-shaped and of different dimensions and cross sections to fit in the appropriate channels and guides of the profiled bars 4 and 5.
  • the secondary profile 31 comprises a secondary first profiled bar 27 made of aluminium preferably or of another metal or alloy, a secondary second profiled bar 28 made of a composite material preferably thermally low conductive, e.g. polyamide, a retainer or clip 36 and two gaskets 29, 30.
  • the secondary first profiled bar 27 has a substantially P-shaped transverse section with a longer side parallel to the plane of the window frame and of the glass pane.
  • the profiled bar 27 contains an empty hollow 61 and several flanges, two of which make the guide or channel 88.
  • the flange 41 is disposed orthogonally to the longer parallel side of the profiled bar and is shorter, with length d1.
  • the secondary second profiled bar 28 has a longitudinal slot or channel 39 which provides a C-shaped transverse section to accommodate the extremity 37 of the clip 36.
  • the secondary second profiled bar 28 has also an extrusion 38, that fits in the guide 88 to fix solidarily the secondary first profiled bar 27 and second profiled bar 28 in appropriate manner for thermal break connections in window profiles.
  • the slot 39 has a width that is not constant along its depth: it is thinner at the entrance but has a wider area in the inner part.
  • the gaskets 29, 30 are fixed by inserting them into the respective open channels 89 and 87. These gaskets, as those of the fixed frame, have both sealing functions and gasket 30 avoids dangerous contacts of the glass surface with other components of the window frame made of metal.
  • the clip 36 keeps the glass pane 3 fixed to the sash frame 2. Its longitudinal dimension is generally of few centimeters and can be made also longer if need arise ( see figure 9 a-b). It has an L-shaped cross section and its extremity 37 has a cogged or ribbed surface to have a better grip in the slot 39 using the flexibility of the composite material that makes the secondary second profiled bar 28.
  • a gasket 35 is also provided to protect the contact with the glass 3.
  • the procedure to mount the glass on the sash frame 2 and to dismount is herein described with particular reference to Figures 5, 6 and 7.
  • the glass pane 3 is inserted into its housing on the sash frame 2 and the extremity 37 of the clip 36 is inserted into the slot 39.
  • the clip 36 can be easily engaged by means of a number of V-shaped spring 90 housed in the slot 39, which has its V vertex 91 directed to the opposite direction of the secondary profiled bar 27 and is elastically pressed against surface 40.
  • V-shaped spring 90 housed in the slot 39, which has its V vertex 91 directed to the opposite direction of the secondary profiled bar 27 and is elastically pressed against surface 40.
  • each cog of the clip cogged surface pushes the V-shaped spring 90 bending it and overtaking it.
  • the V-shaped spring 90 comes back and locks the clip by fitting the edge 92 of the V- shaped spring against the entered cog.
  • the clip position can be fitted to various thicknesses of glass panes by inserting in a different number of cogs and within a predefined range of glass pane thicknesses.
  • the procedure to remove the clip 36 comprises the following steps.
  • a combination of primary first bars 4 and 4’, primary second profiled bars 5, 5’ and 5”, secondary second profiled bar 28, 28'and 28” and clips 36 and 36’ enables to accommodate in the window frame glass panes 3 of thicknesses from 24 to 62 mm without affecting the visual appearance of the window inside and outside as shown in Figures14a to 14f.
  • the sash frame 2 is composed of four joined and mitered secondary profiles 31 , 32, 33, 34 and is connected by four metal corner-cleats 71 , 72, 73, 74 for each corner, which are shown in figures 11a to 11d in axiomatic view. Each cleat is inserted in a corresponding guide or channel of the secondary first and second profiled bars 27 and 28. Thanks to such angular connections, the sash frame 2 is particularly robust and can withstand high loads produced by its own weight and vertical loads from operating the sash as well as high dynamic loads generated by the wind.
  • the invention allows a minimal width of the primary profile 21 and secondary profile 31.
  • the secondary first profiled bar 27 has a different width w2 as shown in figure 4 and is less than the width w1 of the primary first profiled bar 4 to take into account the use of today’s standard ironmongery and the freedom of the manner in which the window frame is fixed on the building structure.
  • the difference between w1 and w2 can be eliminated by using a custom made ironmongery.
  • the width w1 of the primary first profiled bar 4 and width w2 of the secondary first profiled bar 27 are substantially equal. Additionally, the choice of an appropriate length d1 for the flange 41, equal or very close to the length d2 of the flange 10 makes the appearance of the window frame externally symmetrical and renders substantially unrecognizable which side is the operable part and which is the external side, when looking from the outside of the building when the window frame is closed.
  • both primary first profiled bar 4 and secondary first profiled bar 27 form a window frame which have the same distance from the surface of the glass pane thanks to the dimensions d1 and d2, and because of the choice of w1 equal to w2 the window frame appears as a singular surface of the frame on both sides of the window without any possible longitudinal interruption due to other profiled bars.
  • the dimensions d1 and d2 take also into account the dimensions of the gaskets 6 and 30, in those cases here they are used.
  • the window sash frame 2 is composed by a secondary first (alum) profiled bar 27 and a secondary second (composite) profiled bar 28.
  • Those profiled bars cramped together over their full length in order to achieve a composite section following an existing proven process well known in the market and achieving that profiles are working sufficiently together in terms of bending and shear.
  • the joined profiled bars 27 and 28, jointly indicated in the frame as 31 , 32, 33, 34, are mitered at each end and form a frame by corner cleat connections 71 , 72 and 73 (see fig.3).
  • Cleats 71 and 72 are mechanically fixed to the frame members by metal threaded pins (see yellow and red pins in fig. 3).
  • An additional corner cleat 74 is applied and fixed with a fixing pin to the frame (see pin in fig 3).
  • the glass 3 is positioned within the frame and secured against falling out by means of clip 36 that is fixed in position with the stainless steel V spring (see fig.5, 6, 7).
  • Polymeric glass setting blocs are inserted in the space between the glass edges and comer cleats 74 at the window corners in such a way that the glass is only in contact with the sash frame at the corners. In this manner, the dead-load of the glass is diagonally transferred to the base hinge, whilst at the top hinge, the rotation load from the glass dead load is transferred along the top frame profiled bar 34 in tension directly to the top hinge.
  • window fixed frame and sash frame are not loaded by the glass self-weight and vertical loads due to operating the sash along their spans resulting in no bending to the profiled bars and hence a smaller and slender window section profiles (see fig.18).
  • the ironmongery is designed in such a way that when the sash is closed interlocks will be achieved at corner positions and a number of intermediate positions along the perimeter of the window frame (see fig.19).
  • the design of the sash allows up to 130 kg of glass and a vertical live load at the non-hinged side of the glass up to 80 kg resulting from opening operations, with a 1 mm maximum vertical allowable deflection of the sash frame in the opened position.
  • the vertical live load has been considered in combination with the dead load in order to verify mechanical strength Class 4 in accordance with EN 14351-1.
  • the resulting loads are transferred to the fixed frame and building structure as shown in fig 21a-b and 23).
  • Fig. 10 shows that due to the described design the stresses in the aluminum profile and the composite (polyamide) profile of the sash frame remain considerable below the limits and therefore allows for minimum dimensions.
  • the ironmongery comprises interlock devices between the sash and the fixed frame at the corner positions (including hinges, see fig 21a-b and fig. 23) and in correspondence with the above mentioned wind load bracket positions (see fig 22 a-b).
  • Wind pressure or suction loads imposed on the glass are transferred to the window ironmongery interlock devices and in turn directly to the window frame brackets fixed to the building structure.
  • the glass thickness for both structural adequacy and displacement is designed not as being continuously supported along the window frame but rather point supported at each ironmongery interlock/window bracket location. As wind loads are not transferred through the window frame, the framing itself is subjected to very limited bending allowing for a much more slender profile.
  • the targeted 20mm distance of the aluminum profile of the fixed window frame when viewed from the frame to the glass surface complies with the maximum allowed deflection at 2 kPa wind-load whilst stresses in the first and secondary profiles of the sash remain considerably below allowable limits and deflections do not exceed the allowable 2mm (see fig. 10).
  • the sash frame can be designed in accordance with the targeted slenderness.
  • the primary fixed frame 1 is fixed to the building structure at the corner s, one intermediate point at each horizontal frame member and two intermediate points (maximum span 600mm) at each vertical frame member (see fig.20).
  • the dead- and vertical loads from the sash including glass are directly transferred to the top and bottom brackets at the corners along one side of the window the fixed frame members are only required to accommodate the relatively very low dead load of the fixed frame members (self weight) and therefore comply with the targeted slender frame dimensions.
  • Wind-loads from the sash including glass are transferred via the ironmongery interlock points at eorner and intermediate wind bracket locations to the fixed frame and via the brackets of the fixed frame at the same locations to the building structure.
  • the frame members of the sash frame do not exceed a deflection of 2 mm between interlock-points the frame members of the fixed frame are not significantly loaded due to the flexibility of the seals in between sash and fixing frame accommodating such deflections. Therefore the fixed frame can easily comply with the targeted slender frame dimensions.
  • the only substantial bending load on the fixed frame members is a maximum horizontal load to the primary first (aluminum) profiled bar 4 of 0,3kN at the position of gasket 6 and the tip of flange 10 of the primary first profiled bar (see fig. 2) which do not result in substantial stresses in the profile and enable compliance with the targeted slender frame dimensions.
  • the window frame is extremely light and thermally performant, reducing the surfaces where heat exchange occurs.
  • the production cost of the window frame is low, thanks to a wide range configurations and dimensions of windows obtained by coupling a low number of standard parts that can be assembled together easily and quickly.
  • a rather small height w1 and w2 of the window frame 100 of around 60mm can be reached, which is a dimension difficult to obtain with other window frames of the state of the art for such large windows.
  • the window according to the invention contributes to redefine market standards about appearance, performances and low cost.
  • the window according to the invention has better performances, looks better and it is also cheaper.
  • Other advantages of the window according to our invention is a minimized visual impact of the gaskets, no identification of the openable part, the provision of aluminum finishes on both window internal and external sides, an optimization of the thermal performances thanks to a high use of composite profiles and a limited number of components to minimize system logistics.
  • the invention has been described in all details like a window. It is readily apparent to the skilled person that it can also be applied to a door or to any other similar opening of a building without leaving the scope of the patent. Though the window of the invention has been described in an embodiment where the sash can be opened towards the internal of a building, it is apparent to the skilled person that it can be mounted on a building also as an external opening sash. The window of the invention can also be applied in various opening modes and in shapes other than rectangular and square.
