Description

A reversible window, use thereof and a guide device for a reversible window.
The present invention relates to a reversible window comprising a frame and a sash which is displaceably and swingably connected at one end to the frame, and a guide device comprising a tension member which is pivotally connected at one end to the frame, and a pressure rod which is pivotally con- nected at one end to the sash near the latter' s centre of gravity and is connected at the other end to the frame, the other end of the tension member being connected to the pressure rod at a location between the ends of this rod, and use of such rever- sible window.
The present invention also relates to a guide device for a reversible window, the device comprising a tension member which is adapted at one end for pivotal connection with a frame, and a pressure rod which is adapted at one end for pivotal connection with a sash and is adapted at the other end for displaceable connection with the frame, the other end of the tension member being connected to the pressure rod at a location between the ends of this rod. Reversible windows of this type are very practical as front windows as these reversible windows can be rotated substantially 180 degrees, allowing for cleaning of the outside of the window from the inside, which obviously makes it much easier to clean the windows, particularly if they are located high above the ground. Despite this advantage, reversible windows are not much in use, one reason being that the prior-art reversible windows are somewhat more expensive than, for example, top-hung windows, and another reason being that they often deviate in appearance from other windows, thus ruining the architecture of a coherent glass front .
WO 96/17151 describes a reversible window of the above type mounted with a link arm mechanism. The inward-facing side surfaces of the window frame are provided with a groove with which one end of the window sash engages. The link arm mechanism comprises a pressure rod, one end of which also displaceably engages with the frame groove, while the other end of the rod is pivotally fastened to the sash near the latter' s centre of gravity, and a tension rod one end of which is pivotally connected to the frame while the other end is pivotally connected to the pressure rod at a point between the latter' s ends. This window structure requires frame and sash to be custom-made or adapted for this purpose as grooves have to be provided in the opening of the frame, and the frame or the sash must be provided with suitable recesses to make room for the link arm mechanism. Mounting of the link arm mechanism is made difficult because it is mounted inside the opening of the frame, which results in difficult working positions at mounting. WO 00/28184 describes a fitting for a reversible window, one end of the window sash being guided in a guide in the frame. The fitting comprises a telescopic arm which is fastened at one end to the frame and is fastened at the other end to the side jambs of the sash approximately at the centre of gravity of the sash. The fitting also comprises a tension rod which is fastened at one end to the frame and at the other end to the telescopic arm. It is indicated that the tension rod has been made very thin so that it is hardly visible, the rest of the fitting being apparently hidden behind the sash. Also this window structure requires grooves to be provided in the side surfaces of the frame opening for guiding the sash. Mounting of the fitting is also made dif- ficult because the tension rod is mounted inside the opening, which results in a difficult working position, and it will probably also be necessary to provide the frame with a recess to make room for the fitting. It is an object of the present invention to provide a reversible window of the type mentioned in the introduction for particularly simple mounting.
In view of this object, the reversible window is characterized in that the guide device is mounted on the face of the frame. This structure allows very easy mounting of the guide device, as the mounting is not, as in the prior-art reversible windows, made inside the frame opening, but directly on the face of the frame, which results in much better working positions at mounting. Another advantage of this structure is that the reversible window may consist of a standard frame and a standard sash, as special adaptation of the frame or sash is not required or, for example, a particularly narrow sash. It is furthermore advantageous that the guide device is not mounted in the opening of the frame, as no gap or recess between frame and sash is required at mounting on the face of the frame. This allows the use of a standard frame and sash without any need for subsequent refinishing thereof.
In one embodiment, the reversible window is characterized in that the pressure rod consists of a first part hinge-connected to the frame and a second part hinge-connected to the sash, the two parts being in telescopic connection. This makes it possible for the centre of gravity of the sash to move along an approximately rectilinear path outwards from the frame, and at the same time a guide device of a particular size can fit reversible windows of varying sizes as the telescopic connection can absorb this variety.
In an alternative embodiment, the reversible window is characterized in that the pressure rod is displaceably connected at its other end to the frame. This makes it possible in a simple manner for the centre of gravity of the sash to move along an approximately rectilinear path outwards from the frame. In relation to the telescopic connection mentioned above, the displaceably connected pressure rod has the advantage that it consists of fewer parts and also that it provides more reliable guiding of the sash.
Grooves in the frame may, of course, be provided for the displaceable connection, but in a preferred embodiment the reversible window is characterized in that the guide device also comprises a rail extending along the face of the frame substantially in the entire length of the frame and displaceably receiving an engagement member connected to one end of the sash.
In one embodiment, the reversible window is characterized in that the rail displaceably receives the other end of the pressure rod. Since the sash and the pressure rod are displaced in one and the same rail, no more rails are required, which reduces costs and facilitates mounting. The reversible window may, of course, be provided with a guide device in which the tension member and the pressure rod are of the same thickness, but preferably the tension member is substantially thinner than the pressure rod. This is possible since the tension member is only exposed to tensile loads owing to the net weight of the sash and the pane, and dimensioning for tensile loads results in much smaller dimensions than dimensioning for pressure loads, where, for example, deflection also has to be taken into account. It is thus possible to minimize the material consumption for this first arm, and thus also the weight of the complete structure, and moreover the dimensions of the guide device become smaller, and the guide device is thus easier to fit into the reversible window.
In a preferred embodiment, the reversible window is characterized in that, at its sides, the sash is provided with a flange which, in a front view of the window in the closed position, substantially hides the second arm of the guide device. This provides a ' very discreet incorporation of the guide device, as the only visible part of the guide device of a closed window will be the tension member which must be able to pass the exterior of the sash.
Another aspect of the present invention relates to the use of a reversible window of the above type.
The reversible window may, of course, be a single element of, for example, a brick front. However, it is a particular advantage of the present reversible window that it is possible to build a front with several closely spaced windows, the frame part of the reversible window being placed closely up against the frame part of an adjacent window, such as a pivot-hung, tilting or reversible window or a fixed windo .
Due to the construction of the reversible window with a very discreet guide device which, in the closed position of the window, may be substantially hidden by the sash, which may also hide the frame, it is possible to arrange the reversible window closely adjacent to other windows without resulting conspicuous deviations and wide gaps between the window sashes, as would be the case with conventional reversible windows. Of course, this optimum possibility occurs in the cases where, as mentioned above, the sash and frame are standard components which are also used in pivot-hung and tilting windows and fixed windows without opening capacity so that the reversible windows do not deviate in appearance from other windows, thus retaining the architecture of a coherent glass front . Another object of the present invention is to provide a guide device of the type mentioned in the introduction for a reversible window, which guide device is of a design allowing particularly discreet incorporation into a reversible window. In view of this object the guide device is characterized in that the tension member is substantially thinner than the pressure rod, and preferably the thickness of the tension member is not more than one third of the thickness of the pressure rod. This is possible, as the tension member is substantially only exposed to tensile loads which a relatively thin metal arm is well capable of bearing. Since, in the present structure, the tension member is the only part of the guide device that has to pass the exterior of the sash, the visible part of the guide device in the closed position thereby becomes minimal, as the rest of the guide device can be hidden behind the face of the sash. In one embodiment the guide device is characterized in that the tension member has a thickness of less than 2 mm, preferably approximately 1.5 mm. The necessary thickness will depend on the size and weight of the sash with pane, but for front windows of an ordinary size a tension member with a thickness of between 1.5 and 2 mm will be a sensible compromise between reliable guiding of the sash and a discreet guide device. If it is of particular importance to obtain a discreet guide device which is hardly visible, one option is a guide device in which the tension member has a thickness of less than 1.5 mm, and in principle the arm might, for example, be constituted by a thin wire.
In one embodiment the guide device is an integral structure consisting of a rail to which the other end of the pressure rod is displaceably connected, and at the end of which the first end of the tension member is pivotally connected. With the guide device designed as an integral structure, mounting of the device is extremely simple. The rail is thus mounted on the face of the frame, which can be done from the outside in a natural working position, for example, if the fitter is standing on scaffolding. As the rail is pre-fitted with tension member and pressure rod correctly positioned in relation to each other, the tension member merely has to be fastened to the sash and the sash to the rail . The entire mounting can therefore be performed quickly and thus at low cost, and moreover ergonomically correct . A further advantage is that the guide device is an integral structure, as this minimizes the risk that parts of a wrong dimension for the relevant window are used at the mounting, or that parts get lost before or during the mounting of the reversible window. For the fitter it may thus be rather difficult to keep track of many small individual parts if he is working on a restricted area, for example, on scaffolding, and if a part is lost, it often has to be replaced as it is rarely possible to find it again.

Fig. 1 shows a reversible window 1 in a slightly open position, the window 1 comprising a frame 2 and a sash 3 which is displaceably connected at its upper end to the frame 2, for example, by means of a stud in a groove or a slide shoe inserted in a rail. Moreover, at each side the reversible window 1 comprises a guide device 4, which is seen more clearly in Fig. 2, showing a side view of the reversible window 1 in an open position. The guide device com- prises a tension member 5 which is hinge-connected at one end 5a to the frame 2, and a pressure rod 6 which is pivotally connected at one end 6a to the sash 3 approximately at the latter' s centre of gravity and is displaceably connected at its other end 6b to the frame 2, for example, by means of a slide shoe or a stud in engagement with a rail 7. It is apparent that in this open position the tension member 5 passes the side edge of the sash 3. The tension member 5 lies within the external periphery of the frame 2 and may suitably be closely adjacent to this external periphery of the frame 2, as the frame width may correspond to the sash width plus the thickness of the two tension members. In this case it is thus possible to arrange two reversible windows 1 closely adjacent to each other with their respective frames 2 abutting each other discreetly, the sashes 3 hiding the frames 2 and the guide devices 4 apart from a narrow gap corresponding to the double thickness of the tension member 5. Since the tension member 5 may have a thickness of, for example, 1.5 mm, the gap need not be wider than 3 mm, which makes it practically invisible. Furthermore, for the frame and sash, standard components may be used which are also used for the building of pivot-hung and tilting windows as well as fixed windows .
Fig. 3 shows a cross-sectional view of the frame 2 and the sash 3 as well as the pane 8 mounted in the sash. In the Figure the reversible window is shown in the closed position in which the guide device 4 is folded down along the side of the sash 3. It is apparent that the guide device 4 is mounted on the face 2a of the frame 2, the pressure rod 6 being displaceably connected to the rail 7 in the example shown, which is seen in Fig. 5. The sash 3 may suitably be displaceably connected at its upper end to the same rail 7, which is seen in Fig. 4, and the tension member 5 may be hinge-connected at its one end 5a to the rail 7, possibly by means of a fitting mounted thereon as indicated in Figs . 1 and 2. The pressure rod 6 is hinge-connected at one end 6a to the sash 3 at the latter' s outward side opposite to the pane 8. As is apparent, along its sides the sash 3 is provided with a flange 3' which projects beyond the pressure rod 6 and the rail 7 and thus hides the pressure rod 6 and the rail 7 as seen from the front, while the tension member 5, which must be able to pass the sash 3, will be visible from the front past the flange 3' of the sash. However, as is apparent, the tension member 5 is very thin so that, as seen from the front, it will be hard to see it. In a manner not shown, the tension member 5 may be bent in its longitudinal direction so that its cross-section will be a V-shape slightly open outwards. This makes it possible for the tension member 5, which has to pass along the edge of the sash 3, to slide on its middle instead of along its rather sharp edge, which might otherwise scrape the sash 3. The tension member
5 and/or the sash edge may moreover be provided with a coating of a friction-reducing material, such as Teflon. The rail 7 may have its open side outwards, but preferably the rail 7 is open towards the opening of the frame, as shown, as this provides further security against the pressure rod 6 or the sash 3 coming out of engagement with the rail 7 during the opening movement if the outward force becomes large. Instead of a partially closed rail 7 as the one shown, the rail may be completely open, but the rail shown makes it possible to ensure that the slide shoe is always sure of positive engagement with the rail and cannot leave it. As shown, the frame 2 may be provided with an indent for partial reception of the sash 3 in order to obtain good sealing of the window. As is apparent, the reversible window 1 may be designed so that the sash 3 is not seen from the inside, as it will be hidden by the frame 2, and as distinguished from many conventional reversible windows the sash 3 thus does not reduce the opening of the reversible window, thus providing the largest possible light incidence. Fig. 4, which is a sectional view along IV-IV in Fig. 2, shows a section through the frame 2 and the sash 3 at the fastening of the sash 3 to the frame 2 in a slightly open position of the reversible window 1. It is apparent that the sash 3 is dis- placeably connected at its upper end to the frame 2, the sash 3 being provided with a slide shoe 9 engaging with the rail 7, thus providing reliable guiding of the sash 3. In this open position of the reversible window 1, the tension member 5 passes the exterior of the sash 3, passing closely along the exterior of the sash 3 and possibly sliding along the exterior of the sash 3 during the opening movement of the reversible window 1. In the example, the sash 3 is connected to the frame 2 at the upper end of the sash 3, but it is evident that the reverse situation in which the sash 3 is instead displaceably connected to the frame 2 at its lower end is also imaginable, and guide devices 4 may also be conceived for reversal of the reversible window 1 about a vertical axis so that the sash 3 is displaceably connected to the upper and lower members of the frame 2. However, this necessitates a different dimensioning of the arms 5,6, as in this situation the tension member 5 is no longer exposed only to a purely tensile load. Another sectional view through the frame 2 and the sash 3 at a slightly open reversible window 1 is shown in Fig. 5. This Figure, which is a sectional view along V-V in Fig. 2, shows a section through the frame 2 and the sash 3 at the place where the pressure rod 6 is hinge-connected by means of its one end 6a to the sash 3. The pressure rod 6 is connected at its other end 6b to the frame 2, the arm 6 at this other end 6b being provided with a slide shoe 10 in engagement with the rail 7. It is also indicated that the tension member 5 is hinge-connected to the pressure rod 6 at a location between the one end 6a and the other end 6b of the pressure rod 6. The reversible window may also suitably be provided with a locking fitting which can retain the reversible window in the reversed position (cleaning position) to obviate the risk that the window will reverse again during the cleaning. The reversible window may furthermore be provided with means for locking the window against reversal so that this lock has to be actively released before the window can be reversed in order to prevent unintended reversal of the window. This may be particularly suitable to ensure that children or animals do not reverse the window unintentionally, thus risking falling out of the window.
The reversible window may also have some degree of built-in friction so that the sash can be retained in any random position. The friction may, for example, be built into the displaceable connection of the sash to the frame and/or the rail and the pressure rod and may possibly be of an order so that the friction will prevent small children and animals from reversing the window.
The reversible window shown in the drawing and reviewed in the example functions as a top-hung window moving outwards at the bottom, and in general use it will not differ substantially from a top-hung win- dow, but naturally with the built-in extra option of reversing the window substantially 180 degrees so that the window can be cleaned from the inside. Alternatively, the reversible window may have a function as a bottom-hung window moving outwards at the top, which is sometimes preferred, for example in view of ventilation and to prevent draughts in the room.
