Definitions

  • the invention relates to a window comprising a frame and a sash, said sash being connected with the frame by means of a hinge device defining a hinge axis of the window, the frame and the sash each including a first pair of mutually opposite members, and a second pair of mutually opposite members, said hinge device connecting a respective frame and sash member of the second pair of frame and sash members, and a centre line being defined substantially midway between the one and the other of the members of said first pair.
  • Windows of the pivoting or centre-hung type have found widespread acceptance, especially as roof windows, inter alia because this kind of window facilitates easy window cleaning, as the sash comprising the pane can be turned essentially 180° to allow cleaning of the outside surface of the pane from inside the building.
  • a further advantage of this type of window is that it can be fully opened to a position where the sash is turned approximately 90° in which position air inlet is essentially unrestricted.
  • a pivoting window provides for an easy operation, partly due to the position of the operating means at the top member of the sash, partly because the weight of the sash is substantially balanced with the hinge axis situated close to the centre line of the window.
  • a window of this kind is known from GB 844492 B .
  • This window as well as several others of its kind, however, suffers from the disadvantage, that the opening area is restricted by the frame bottom and side members and the intersection with the sash including the window pane at the hinge axis is, of course, substantially smaller than in a top-hung window of the same size.
  • This entails, i.a., that pivoting windows are not or only rarely used when a large opening area as defined in the above is desired.
  • Such desired applications may e.g. include the use of the window as an emergency escape or emergency access.
  • EP publications Nos. 679774 , 679775 , 679776 and 972885 each discloses a window, in which a sash is carried in an auxiliary frame or a set of arms.
  • the auxiliary frame or each arm is at one end hingedly connected with the frame top member and at its other end with the sash.
  • the sash is furthermore connected with the frame by means of cooperating sliding means.
  • the window may serve as a top-hung window, in which the arms move synchronically with the sash, which is thus rotated about the hinge connection at the frame top member, or as a tilting window.
  • the design is rather elaborate.
  • a window of the kind mentioned in the introduction which is furthermore characterized in that the hinge device comprises a set of pivot hinges mounted in such a position that the hinge axis is situated between said centre line and said one member of said first pair and that at least one of said pivot hinges comprises check means restricting the movement of the window during opening and/or closing thereof.
  • a substantially larger opening is obtained.
  • the same pivot hinge used in existing pivoting window may be placed in another position of the frame and sash side members.
  • a further advantage of moving the hinge axis to a position above the centre line is, that the upper part of the window standing out into the room behind the window becomes smaller. This entails that the risk of e.g. hitting ones head on the window is reduced. In addition it is an advantage when using screens and blinds since these may now be employed even when the window is open for airing or ventilation without having to be passed around a projecting top of the sash.
  • the displacement of the hinge axis also means that the weight of the two parts of the sash and pane lying on each side of the hinge axis, when the window is in its open position, is no longer the same. Due to gravitational forces the larger part of the sash and pane will therefore be drawn downwards. If the hinge axis is moved upwards in a traditional pivot window, the window will thus tend to fall back against the closed position, making it difficult or impossible to leave the window in a half-open position.
  • the provision of check means according to the invention solves this problem.
  • the hinge axis is positioned in the interval between 1/3 and 2/3 of the distance between the centre line and said one member of said first pair, preferably at approximately 1/4 of the distance between the centre line and said one member of said first pair, there is a good balance between a relatively large opening on the one hand and a satisfactory operability of the window on the other.
  • Check means providing a smooth resistance during operation of the window will be adequate for most purposes. However, if for example heavy winds are to be expected it is preferred that the check means allows the window to be arrested in one or more predetermined positions. For example an only slightly open ventilating position, a more open airing position and a fully open emergency escape position.
  • Each pivot hinge in the set of hinges may include a first hinge member for connection with the frame member of the second pair and a second hinge member for connection with the sash member of the second pair, where one or more parts of each of the hinge members serves as check means by interaction there between.
  • This kind of pivot hinge has proven to provide a structurally simple and well-functioning solution.
  • a leaf spring acting as a check means arranged on or in connection with the first hinge member.
  • At least one part of the hinge is provided with one or more arresting points, where other parts of the hinge may come into a particularly tight contact therewith.
  • Such arresting points may be depressions, grooves or holes in one of the hinge parts designed to interact with buckles or projections on the other hinge part.
  • Arresting points provided in this manner is capable of arresting the window even when in the fully open position, thus allowing the use as an emergency exit without risking, that the window falls back blocking the exit and possibly hurting someone.
  • the arresting points may also be formed as areas of increased roughness causing a locally increased friction between the interacting hinge parts.
  • the number of arresting points depends on several factors such as the design of the hinge, the design and size of the window and the intended use of the window.
  • a fourth position might for example be desirable when the window is provided with a screening device, this fourth position corresponding to the maximal possible opening of the window when the screen is in use. It is therefore preferred, that said check means have between two and six arresting points.
  • the check means has no or little effect when the window is being moved against the force of gravity. The user then only has to lift the actual weight of the window when opening it, while the closing of the window caused by gravity is restricted.
  • the window shown in Fig. 1 comprises a frame 1 with a first and a second pair of mutually opposite frame members.
  • the first pair consists of one member in the form of a top member 3 and another member in the form of a bottom member 4.
  • the two members of the second pair constitutes side members 5 and 6, each extending between the top and bottom members 3 and 4 to form a substantially rectangular frame 1 intended to be built-in in e.g. an inclined roof (not shown).
  • a sash generally designated 2 is constructed in a similar manner with a top member 7, a bottom member 8 and side members 9, 10.
  • a window pane 11 of any type, e.g. an insulating unit, is enchased.
  • the sash 2 is connected with the frame 1 by means of a hinge device, which in the embodiment shown comprises a set of hinges, of which one hinge 12 is shown in Fig. 1, at corresponding side members 5 and 9, and 6 and 10, respectively, of the frame 1 and sash 2.
  • the set of hinges may be designed e.g. as disclosed in Applicant's European patent No. 1038083 , the contents of which are incorporated herein by reference.
  • Each hinge 12 thus includes a first hinge member for connection with the frame side member 5, 6 and a second hinge member for connection with the sash side 9, 10 member of the second pair, and the hinge 12 includes cooperating pins and guides as disclosed in further detail in the above-mentioned European patent.
  • pivot hinge in particular with cooperating pins and guides, makes it possible to establish an overlap between the sash and the frame in the closed position of the window, without the use of elaborate devices such as linkage mechanisms. This is a particularly important feature in windows installed in a roof.
  • Several other parts of a traditional pivoting window may be simply transferred to the window according to the invention, possibly following a slight adaptation. This includes, i.a., some of the cladding parts that protect the frame and the sash from the weather.
  • the set of hinges 12 define a hinge axis 13 extending substantially perpendicular to the plane of the Fig. 2.
  • the hinges 12 are positioned between the top members 3 and 7 of the frame 1 and the sash 2, respectively, and a centre line 14 of the window.
  • the centre line 14 is situated substantially midway between the top and bottom members 3 and 4 of the frame 1, corresponding in substance to the position midway between the top and bottom members 7 and 8 of the sash 2.
  • the position of the hinge axis 13 is chosen in such a way that a suitable balance between ease of operation of the window and a suitable opening defined by the bottom member 4, the side members 5 and 6, and the intersection of the sash 2 including the pane 11 at the hinge axis 13.
  • the distance d between the hinge axis 13 and the centre line 14 of the window lies in the interval between 1/3 and 2/3 of the distance between the centre line 14 and the top member 3 of the frame 1.
  • the operating means comprises a handle bar 15 on the sash top member 7.
  • the handle bar 15 includes engagement means for cooperation with engagement means on the frame top member 3.
  • the unit comprising sash 2 and pane 11 is not balanced in relation to the frame 1, as is the case in a traditional pivoting window.
  • the force to be exerted by the user when opening the window according to the invention is thus larger than in a traditional window. This, however, may not be experienced as any particular disadvantage.
  • Fig. 3 shows a possible embodiment of a hinge for use in a window according to the invention.
  • the hinge comprises two main hinge members 21 and 22 intended for mounting on the frame and sash, respectively.
  • Mounted on the frame hinge member 21 is a leaf spring 23.
  • a pin 25 on the sash hinge member 22 will travel along the spring 23 and due to the limited space between the spring and the guide 26 lying above the spring in Fig. 3, the pin will be forced against the spring.
  • the spring thus constantly exerts a pressure against the pin causing a checking of the movement of the window.
  • the window may thus be left in any desired position and will stay there irrespective of the action of gravity.
  • the spring force should be strong enough to keep the window in a desired position even when affected by wind forces.
  • the spring 23 is further provided with a number of depressions 24. When reaching one of these depressions the pin 25 will settle into the depression and an extra force therefore has to be exerted to move the window any further.
  • the force needed to bring the pin out of the depression should be large enough to prevent the window from being moved by normal wind forces, but it should still be possible for the user of the window to overcome the force.
  • the shown depressions 24 are evenly spaced. They may, however, also be arranged corresponding to the window being kept in specially desired positions such as an only slightly open ventilating position, a more open airing position and a fully open emergency escape position. Additionally a position where the top of the sash does not project into the room behind the window may be desirable where the window is to fitted with an insect screen, a roller blind or the like.
  • a similar hinge without a spring could also be used.
  • the guide 26 might be provided with one or more projecting resilient members. When opening the window the pin 25 would then travel along the guide meeting little or no resistance until reaching the projecting member. To travel further the pin would have to force aside the resilient member, the necessary force depending on the material and design of the latter.
  • the window may be built-in in a facade
  • the sash may be hingedly connected with the frame with the hinge axis extending in parallel with the side members of the frame and the sash.
