Description

Reversible windows, their use and guides used on reversible windows

technical field

The invention relates to a reversible window: it comprises a window frame, a sash and a guide device, wherein the sash is connected to the window frame at one end to be movable and reversible, and the guide device includes a pivotally connected to the tension member of the window frame and a compression rod pivotally connected at one end to the vicinity of the center of gravity of the sash, the other end of the compression rod is connected to the window frame, and the other end of the tension member is connected to the compression rod The invention also relates to the use of such a reversible window at a position between its two ends.

The invention also relates to a guiding device for a reversible window, the guiding device comprising: a tension member pivotally connected to a window frame at one end; A window sash is pivotally connected, and its other end can be movably connected with the window frame, and the other end of the tension member is connected to a position between two ends of the pressing rod.

Background technique

The above-mentioned type of reversible window is most often used as a front window, because this type of reversible window can be turned roughly 180 degrees. Since the outside of the window can be cleaned from the interior side, it is obviously much easier to clean, especially In cases where the windows are elevated above the ground. Even so, reversible windows are not used much: on the one hand, the reason is that existing reversible windows are more or less expensive compared with top-hung windows; The appearance is different from the rest of the windows, thereby compromising the architectural uniformity of the glazed façade.

WO96/17151 describes a reversible window equipped with a linkage mechanism. Wherein the inner side of the window frame has a guide groove to engage with one end of the window sash. The link mechanism includes: a pressing rod, one end of which is also movably matched with the slot of the window frame, and the other end is pivotally connected near the center of gravity of the window sash; and a tension rod, one end of which is pivotally connected to the window frame, and the other end One end is pivotally connected to the position between the two ends of the pressure rod. Such a window structure requires custom-made window frames and sash, that is to say, it must be modified according to local conditions. Accommodates the linkage mechanism. Because the link mechanism will be installed in the window frame opening, it is difficult to install, that is, it is difficult to install in place.

WO 00/28184 describes an adapter for reversible windows in which one end of the sash is guided by a guide provided in the window frame. The coupling device includes a telescoping telescopic arm connected at one end to the frame and at the other end to the edge of the sash at approximately the center of gravity of the sash. The adapter also includes a tension rod that is connected to the window frame at one end and to the telescoping arm at the other end. Among them, the tension rod is made so thin that it is almost invisible, and the rest of the matching device is hidden behind the window sash. This window structure also requires guide grooves to be made on the sides of the window frame opening to guide the sash. Fitting the adapter in place is difficult due to the tension rod being seated in the window frame opening; and this still requires making a recess in the window frame to accommodate the adapter.

US4,616,443 introduces a reversible window, which is used to prevent the sash from protruding into the room from the window frame and facilitate the reversing operation when the sash is turned over. The window includes a tension member and a movable joint arranged between a compression rod and a window frame.

DE 43 14 404 describes a conversion mechanism for converting a pitch roof swing window into a top hinged swing window via an intermediate sash. The converted window includes a swingable arm attached at one end to the upper portion of the window frame and at the other end to the sash.

Contents of the invention

The object of the invention is to provide a reversible window which is particularly simple to install.

According to the above objects, the reversible window of the present invention is characterized in that the guiding means are mounted on the front side of the window frame. This structure can easily install the guide device. Compared with the reversible window in the prior art, in the present invention, the installation is not carried out inside the opening of the window frame, but directly installed on the front of the window frame. Of course, it is much more convenient to install this way. The structural advantage of the present invention is also that the reversible window is made of a standard window frame and a standard sash, so there is no need to make special modifications to the window frame and sash, such as a particularly narrow sash. The invention also has the advantage that the guide is not installed in the window frame hole, so when installed at the front of the window frame, no gap or groove is required between the window frame and the sash. This allows standard window frames and sashes to be used without trimming them.

In one embodiment of the invention, the reversible window is characterized in that the strut comprises a first part hinged to the frame, and a second part hinged to the sash, said first and second parts It is telescopically connected. This allows the center of gravity of the sash to move outwards from the frame in a generally straight line, while on the other hand a guide of a given size can be adapted to different sizes of reversible windows because the telescopic Telescoping connections are able to accommodate said dimensional differences.

In another embodiment of the invention, the reversible window is characterized in that the strut is movably connected to the window frame at its other end. This makes it easier to move the center of gravity of the sash along a generally straight line outwardly from the frame. Compared with the above-mentioned telescopic telescopic connection, the movably connected pressing rod has the advantage of fewer components and can provide more reliable guidance for the window sash.

Of course, a guide groove can be provided on the window frame to realize the above-mentioned movable connection, however, in a preferred embodiment of the present invention, the feature of the reversible window is that the guide device also includes a track, the track Extending the entire length of the window frame along the front side of the window frame and movably receiving an adapter, the adapter is connected to one end of the window sash.

In yet another preferred embodiment of the present invention, the feature of the reversible window is that the track movably accommodates the other end of the pressing rod. Since the window sash and the pressure rod are staggered and installed on the same track, there is no need to install another track, thereby reducing costs and simplifying installation.

Of course, the reversible window of the present invention can be provided with a guiding device, wherein the tension member and the pressure rod can be selected to be the same thickness; but better, the tension member is much thinner than the pressure rod. This is because the tensile member is only subjected to the tensile force generated by the net weight of the sash and the glass plate, and considering problems such as deflection, the required member size for tensile force is much smaller than that required for compressive force. This minimizes the material consumption of the primary boom while also reducing the weight of the entire structure. Also, the reduced size of the guides makes it easier to install them in reversible windows.

In yet another preferred embodiment of the present invention, the reversible window is characterized in that, in the closed state of the window, viewed from its front side, a flange is provided on both sides of the sash to substantially cover the second side of the guide device. boom. This leads to a very good fit of the guide, that is to say that in the closed state of the window the only visible part of the guide is only the tension member which necessarily intersects the outer edge of the sash.

Another aspect of the invention relates to the use of a reversible window as described above.

Of course, the reversible window of the present invention can be installed individually in the brick front wall. However, the special advantage of the reversible window of the present invention is that several closely spaced windows can be utilized to form a front wall, the sash of the reversible window being placed side by side with the sash of an adjacent window, Such as hinged reversible windows or fixed windows.

Since the reversible window has a well-designed guide structure, in the closed state of the reversible window, the guide is almost completely covered by the sash, and the sash also covers the window frame at the same time, therefore, Reversible windows can be fitted side by side with other windows without significant misalignment and gaps between the sashes, which is not possible with existing reversible windows. Of course, the best part of the present invention is that, as mentioned above, the window frame and sash can still adopt the standard components used on hinged windows and fixed windows, without affecting the ventilation and light transmission ability, thereby, The reversible windows are not different from other windows in appearance, maintaining the architectural uniformity of the glass curtain wall.

Another object of the present invention is to provide a guide device for the above-mentioned reversible window, carefully designed to fit into the reversible window.

To achieve this object, the guiding device according to the invention is characterized in that the tension element is much thinner than the compression bar, preferably the transverse dimension of the tension element does not exceed one-third of the transverse dimension of the compression bar. This is of course possible, since the tension member basically only takes the tension, and a fairly thin metal strip is enough to bear the tension. Moreover, in the structure of the present invention, the tension member is the only part of the guide that intersects with the outer edge of the sash, so the visible part of the guide in the closed position of the window is very small, The remainder of the guide is shaded by the front of the sash.

In yet another preferred embodiment of the invention, the guiding device is characterized in that the transverse dimension of the tension member is less than 2 mm, preferably less than about 1.5 mm. The required lateral dimensions depend on the size and weight of the sash and the glass plate it is attached to, but for a front window of normal size, a tension member with a thickness of 1.5-2 mm can take into account the reliable guidance and guiding device of the sash of compact size. If in particular an almost invisible compact guide is desired, the tension member can be selected to have a thickness of less than 1.5 mm, which can even in principle be, for example, a thin wire.

In yet another preferred embodiment of the present invention, the guiding device is an integral structure including a rail, the other end of the pressing rod is movably connected to the rail, and the other end of the pressing rod is pivotally connected to the first end of the tension member. Since the guiding device is designed as an integral structure, it is extremely simple to install. The track is installed on the front of the window frame, which can be done from the outside in a natural working position, such as the installer standing on scaffolding. Because the track, the tension piece and the pressure bar are installed in place accurately in advance, it only needs to fix the tension piece on the window sash and fix the window sash on the track. As a result, the entire installation operation is quick and cost-effective, and it is also easy for personnel to operate. Since the guide is a one-piece construction, the risk of using the wrong part when installing the relevant window is minimized, and it is also prevented that parts are lost before and during the installation of the reversible window. If installers are working in restricted areas, such as scaffolding, it is difficult for them to carry and keep track of the many individual small parts. If a part is lost, it is almost impossible to find it, often Made it up.

Description of drawings

The present invention will be described in detail below with reference to embodiment and accompanying drawing:

Figure 1 is a perspective view of the reversible window of the present invention in an open position;

Fig. 2 is the side view of described reversible window;

Fig. 3 is a sectional view of the window frame and sash of the reversible window;

Figure 4 is a sectional view along line IV-IV in Figure 2; and

Fig. 5 is a sectional view along line V-V in Fig. 2 .

Detailed ways

Figure 1 shows a reversible window 1 in a slightly open position. The window 1 comprises a frame 2 and a sash 3, the latter being movably connected to the frame 2 at its upper end, for example by fitting a stud into a guide groove or a slider into a guide rail. Also, the reversible window 1 is provided with a guide device 4 on both sides, which can be seen more clearly in FIG. 2 , which is a side view of the window 1 in the open position. The guiding device comprises: a tension member 5, hinged at one end 5a of the window frame 2; and a pressure rod 6, at one end 6a of which is pivotally connected to the center of gravity of the window sash 3, and whose other end 6b is movably connected to the The window frame 2 can be connected, for example, with a column head or a slide block and a guide rail 7. Obviously, at this window opening position, the tension member 5 is intersected with the side edge of the window sash 3. The tension member 5 is located within the outer periphery of the window frame 2 and can be close to the outer periphery of the window frame 2 because the width of the window frame can be equal to the width of the sash plus the thickness of the two tension members. In this way, two reversible windows 1 can be installed close together so that the corresponding window frames 2 are connected together; except for the narrow gap corresponding to the double thickness of the tension member 5, the sash 3 holds the window frame 2 And the guiding device 4 is covered up. For example, since the tension member 5 can be as thin as 1.5 mm in thickness, the slit width need not be more than 3 mm wide, which is actually not at all noticeable. That is, standard components used for hinged and tilted windows can be used in the frame and sash of the present invention.

Fig. 3 is a cross-sectional view of the window frame 2 and sash 3 and the glass plate 8 installed in the sash. This figure shows the reversible window in the closed position, ie the guiding device 4 is folded down along the sides of the sash 3 . It can be clearly seen from the figure that the guide device 4 is installed on the front side 2a of the window frame 2, and in the example shown, the pressing rod 6 is movably connected to the rail 7, which can be seen from FIG. 5 . The sash 3 is movably connected to said track 7 at its upper end, as shown in FIG. 4; The pressure rod 6 is hinged at its one end 6 a to the outside of the window sash 3 , the so-called outside is relative to the glass plate 8 . It can be seen that the window sash 3 is provided with a flange 3' along its side, and the flange 3' protrudes farther than the pressure rod 6 and the track 7, thereby covering the pressure rod 6 and the track 7 from the front; The tension member 5 which will intersect the sash 3 is visible from the front through the flange 3' of the sash. However, it is obvious that since the tension member 5 is very thin, it is almost invisible from the front. The tension member 5 can be bent into a slightly upwardly open V shape along its longitudinal direction in a manner not shown in the figure. This enables the tension member 5 running along the edge of the window sash 3 to slide in the middle of the window sash instead of sliding along its front edge, so as to avoid scratching the window sash 3 . In addition, the tension member 5 and/or the edge of the window sash can be coated with anti-friction material, such as polytetrafluoroethylene. The track 7 can have an outwardly open side, but the track 7 is preferably opened toward the window frame opening, as shown in the figure, so that the pressure rod 6 or the window sash 3 can be prevented from opening the window when the outward force is relatively large. Time to disengage from track 7. As shown in the figure, it is a semi-closed track 7, but the track can also be made into a full opening. However, the track shown in the figure can ensure that the slide block is always firmly engaged with the track and will not disengage. As shown in the figure, the window frame 2 can be made with a depression to partially accommodate the sash 3 to achieve a good seal of the window. Obviously, the reversible window 1 can be designed so that the sash 3 cannot be seen from the inside, that is, it is covered by the window frame 2; compared with many existing reversible windows, the sash 3 of the present invention will not reduce The opening of the reversible window can provide as much incident light as possible.

Fig. 4 is a sectional view along IV-IV in Fig. 2, the section passes through the window frame 2 and the sash 3, showing that the sash 3 has been installed on the window frame 2, and the reversible window 1 is in the slightly open position. It can be seen that the window sash 3 is movably connected to the window frame 2 at its upper end, and the window sash 3 is equipped with a sliding block 9 engaged with the rail 7, thereby providing reliable guidance for the window sash 3 . In the open position of the reversible window 1, the tension member 5 intersects with the outer edge of the sash 3, that is, when the reversible window 1 is opened, it passes close to the outer edge of the sash 3 and can pass along the outer edge of the sash 3. Swipe along. In this embodiment, the window sash 3 is connected to the window frame 2 at its upper end. It is obviously conceivable that, in the case of turning over, the sash 3 is instead movably connected to the frame 2 at its lower end; it is also conceivable that the guide 4 is turned over for turning around a vertical axis. Type window 1, like this, sash 3 is movably connected to the upper part and the lower part of window frame 2. However, the shape and size of the arms 5 and 6 will be changed in this way, because in this case, the tension member 5 will no longer be subjected to pure tension.

FIG. 5 shows another section through the frame 2 and the sash 3 with the reversible window 1 slightly open. That is, a sectional view along line V-V in FIG. 2 , which shows a section through the window frame 2 and the window sash 3 at the position where the one end 6a of the pressure rod 6 is hinged to the window sash 3 . The other end 6b of the pressing rod 6 is connected to the window frame 2, and the pressing rod 6 is provided with a slide block 10 matched with the track 7 at the end 6b. It can also be seen that the tension member 5 is hinged on the compression rod 6 at a position between the two ends 6 a and 6 b of the compression rod 6 .

The reversible window may also be provided with a locking fitting to secure the reversible window in the reversible position (scrubbing position) to prevent the window from being reversible during scrubbing.

The reversible window can also be equipped with a device that locks the window to prevent it from being turned over. Only when the locking device is opened at first can the window be turned over, thereby preventing the window from being turned over inadvertently. This is particularly suitable for preventing children or animals from inadvertently turning the window over and falling out of the window.

There may be a degree of internal friction on reversible windows to allow the sash to rest in either position. For example, friction can be created at the moveable connection between the sash and the frame and/or the track and the strut, sufficient to prevent children and animals from turning the window.

The above example shows a reversible window used as a top-hinged and bottom-swinging window, which in practice is significantly different from a top-hinged window, but has the added benefit of turning the window nearly 180 degrees. Select, so that the windows can be scrubbed inside the house. Alternatively, reversible windows can be used as windows that are hinged at the bottom and swing out at the top, which may be preferable in certain circumstances, such as for ventilation and protection from flooding.
