Description

technical field

The invention relates to a shed window, in particular to a shed window with a covering device for covering the outside and a covering mechanism for covering the shed window.

State of the art

Various types of outer coverings for windows are known in the prior art, such as blinds, blinds, roller shutters, folding shutters or sliding shutters. The coverings are mainly used to protect the window and/or building opening, whereby the aesthetic aspect of the outer covering often also plays an important role.

A popular type of cover for skylights is the roller shutter, which can be rolled up or folded into a roller shutter box. In order to meet the aesthetic requirements, it is desirable to visually hide the roller shutter box. This will in CH20130001388 achieved by arranging the roof window and cover in the roof opening in such a way that the roller shutter box is below the surface of the roof and is therefore not visible from the outside.

Outside covers protect, for example, from the sun, rain, wind, but also heat and/or cold. According to the specific requirements, the appropriate type of covering device can be selected.

The type of window to be covered also determines the appropriate type of cover. There are already several solutions for Covering of windows, which have one or two sashes, is known in the prior art. However, a satisfactory solution for covering the outside of shed windows has not yet been described.

Presentation of the invention

It is an object of the invention to remedy the deficiencies of the prior art and to provide a shed window with an outer cover that efficiently protects the shed window in its open and closed state against environmental events, for example against weather events, or against other adverse events such as for example burglaries, protects.

It is a further object of the invention that the outer covering of the shed window be arranged in a space-saving manner.

Furthermore, it is desirable that the outer covering of the shed window be reversibly retractable. It should also be able to meet aesthetic demands.

According to the invention, this object is achieved according to claim 1. The shed window with cover device has a shed window, an outer cover and two fixing axes. The shed window can assume an open and a closed state and has a plurality of co-rotatable, parallel sheds each having a shed axis of rotation, the shed axis of rotation of each shed being arranged parallel to a window frame plane of the shed window. The outer covering is arranged parallel to the window frame plane of the shed window in said open and closed states of the shed window. The rotational movement of the outer covering in relation to the scales of the scale window is dictated by two geometric fixation axes. The two Fixation axles connect the outer cover to scales in a rotatable manner.

Ideally, all opening scales of the shed window are of identical or nearly identical dimensions.

For better lighting of the interior, the shed window can have transparent or translucent sheds, for example. However, the scales can also be opaque. Various colored versions, patterns and/or surface structures are possible.

The parallel arrangement of the outer cover relative to the plane of the window frame ensures that the cover is always kept at a defined distance close to the window, but not on top of it, both when the window is open and closed and in the transitional positions between these states. This is space-saving.

This arrangement offers the additional advantage that environmental influences, such as weather influences, which act on the window, the window opening and/or the interior are largely reduced. This is based on the fact that the open areas through which various environmental influences, such as rain or sunshine, can act, are kept as small as possible by the arrangement mentioned. If the outer covering is a sun or rain cover, only very oblique, or almost horizontally incident light rays or rain can penetrate through the open area between the raised outer covering and the window frame.

Optionally, one or both of the sheds positioned at the window ends can be held closed during opening to further reduce the area through which environmental agents can enter.

The outer cover can also serve as a burglary protection if, for example, the cover surface and the frame are made of solid material. Fixing the cover on the shed window close to the window prevents people from wantonly getting in through the window.

Further advantageous embodiments are specified in the subclaims.

In one embodiment, the outer cover is attached by fasteners to two sheds, one of the sheds being positioned in a first section near the end of the shed window and a second shed being positioned in a second section near the opposite end of the shed window. This arrangement of the fixing sheds in the shed window has the advantage of stabilizing the outer covering.

The exact position of the two fixing scales within the respective sections can be varied. The stability of the cover is higher when the fixing scales are placed near the opposite ends of the scale window.

The outer cover is preferably attached to exactly two fixing scales. Alternatively, the outer cover can also be attached to several sheds. The number of attachments to fixing sheds can be selected depending on the size of the window.

The opening angles of the angle α enclosed by the outer covering and a fixing scale and of the angle α1 enclosed by a fixing scale and the plane of the window frame are identical or almost identical. Said angles remain identical or nearly identical in open and closed states, as well as in the transition positions between the states. This has the advantage that the outer covering is arranged parallel to the plane of the window frame.

In one embodiment, fixation scales are connected to the outer cover by means of hinges. These hinges have a hinge axis around which two tabs can rotate. A first tab of the hinge is attached to a fixing scale, a second tab is attached to the outer shading. In this exemplary embodiment, the geometric fixation axes are each formed by at least one hinge axis. Each fixation axis is preferably defined by at least two hinge axes.

In a preferred embodiment, two hinges are mounted in close proximity to a first longitudinal edge of the fixing scale, this first longitudinal edge being that edge of the scale which is closest to the outer cover when the scale window is open. A first and a second outer edge of the fixing scales run between said first longitudinal edge and the opposite, parallel second longitudinal edge, which is closest to the interior space in the open state. In this preferred exemplary embodiment, each of the two hinges is fastened in the immediate vicinity of an outer edge. The two hinges are preferably flush with these outer edges, with the hinge axis running parallel to the first longitudinal edge.

Ideally, the fixation axis is in the immediate vicinity of the first longitudinal edge of the fixation scale window. This arrangement prevents the freedom of rotation about the fixing axes and about the scale rotation axes from being blocked by contact of the outer cover on the first longitudinal edges of the scales. This has the advantage that the outer cover can be raised as much as possible, which is achieved with an opening angle of the scales of at most 90 degrees, preferably 90 degrees.

In one embodiment, the second tabs have a shape that causes the outer cover to rise and thus establish a distance (d) between the outer cover and the fixing scale. These Distance can be achieved, for example, by an inverted-planar L-shaped configuration of the second tab. The distance (d) can also be created by a hinge attachment that is mounted on the second flap and connects the second flap to the outer cover.

The created distance (d) has the advantage that the first longitudinal edges of the scales do not touch the outer covering. Thus, on the one hand, scratching or wear and tear on the scales and/or the outer cover is avoided. Furthermore, it also prevents the opening mechanism from being blocked, for example, by a faster-opening scale or a larger scale.

Furthermore, the created distance (d) ensures good warm air dissipation between the shading and the window sheds, both when the shed window is open and closed.

The outer cover is fixed overlying the hinge attachment of the second flap or a portion of the second flap of the hinge. This fixed arrangement causes the outer cover to be raised during the opening process in the course of the rotational movement of the fixing scales about their respective scale rotation axis. In the open state, the outer cover is held in the raised position due to its rotationally fixed attachment to the fixing scales. The rotational movement of the fixing scales about the axis of rotation of the scales is reversible, which means that the raising and lowering of the outer cover is also reversible. Due to the rotational attachment of the fixing scales to the outer cover, the rotational movement of the fixing scales is synchronized with the oblique translational movement of the outer cover during its raising and lowering. During the closing process, the outer cover is lowered in the direction of the window frame level. When closed, the outer cover occupies a position parallel to the plane of the window, the distance to the scales being the execution of the second Hinge plate is determined. Said position can be selected at a distance or close to the window, but should not be on top of the window.

Fasteners or hinges may be glued to the outer cover and fixation scales. They can also be attached to the outer cover and fixing scales by means of a fixing device (524), for example a screw. In order to create better stability, in a preferred exemplary embodiment, hinges are both glued and additionally screwed to the fixing scale and/or the outer cover.

If reversible attachment is desired, adhesive attachment of the hinge to either the outer cover or the fixation scale can be dispensed with. It is possible to add other additional devices for reversibly attaching the outer covering to either the fixing scales or the outer covering.

In one embodiment, the outer cover has a frame that defines the perimeter of the outer cover. The material of this frame may differ from the material of the cover surface enclosed by the frame. Preferably, the material is a strong, weather-resistant material such as aluminum, stainless steel, polyvinyl chloride (PVC), wood, or other sheet metal material. In a preferred embodiment, the hinges are fixed to the frame of the outer cover.

An outer cover with a frame has the advantage that the cover surface surrounded by the frame can be chosen as desired. Materials can be chosen according to the intended function or the desired appearance of the outer cover. Because the fasteners can be attached to the rams, these materials may not necessarily be suitable for attaching hinges. This allows flexible or lightweight materials to be used as cover surfaces. For example, different Forms of textiles or plastics can be selected for shading covers. Appropriate water-repellent materials can be chosen to protect against rain.

An outer covering with frame and covering surface offers the further advantage that the covering surface can be removed or pulled back, for example rolled up or folded up, in a reversible manner. Common roller shutter models or a slat blind model are conceivable for this. The reversibly retractable cover surfaces are preferably stored in a cover box in the retracted state. This cover box for receiving the cover is suitably attached to one end of the outer cover.

Hiding the cover box may be desirable for aesthetic reasons. In lowered skylights, for example, it is possible to install the cover box below the roof covering, such as the roof tiles. The cover box can also be stored flush with the roof covering.

In a further exemplary embodiment, the outer cover can be used as insulation or heat protection. The outer cover can, for example, reduce the ingress of external heat into an interior space. In such an embodiment, the outer cover can be a perforated metal plate, a grating or expanded metal.

The present invention leaves a wide scope for possible variations of materials and embodiments, which can be chosen or varied according to the requirements for the outer cover. The outer cover of the shed window is therefore very versatile.

The set out shed window with external cover is particularly useful as a roof window, building exterior window or window for suitable for production halls. Furthermore, the shed window with external cover can be used in other spatial structures, such as in greenhouses. Other suitable applications are certainly conceivable.

Ways to carry out the invention

The embodiment according to the invention is described below using the example of a shed window (2) with an outer covering (3) which has a frame (31) and a reversibly retractable covering surface (32).

The invention was illustrated with only one embodiment. However, the invention is not limited to this exemplary embodiment. Other embodiments are possible.

figure 1 shows a three-dimensional overall view of the shed window (2) with attached outer cover (3) in the open state of the window. The outer cover (3) is rotatively fastened to two fixing scales (21) of the window by means of hinges (5).

The hinges (5) are designed with two hinge straps (51, 52) and a hinge axis (53) around which the two straps rotate. By their attachment in close proximity and parallel to the first longitudinal edge of the fixation shed window (22), which is the edge that is closest to the outer cover when the shed window is open, the hinges (5) define the geometric fixation axes (505), where in Figure 1a two fixation axes (551, 552) are shown. The second longitudinal edge of the scales runs parallel to the first longitudinal edge and is the edge that is closest to the interior when the scales are open.

For reasons of improved stability, it is advantageous to use the hinges (5) as shown in Figure 1a shown, to be attached near the lateral outer edges, preferably flush with them.

The individual sheds (21, 22) are rotationally fixed to the frame of the shed window (40) by opening elements (24). Together with the other scales, each scale performs an opening and closing rotational movement about its geometric scale rotation axes (205). The scale rotation axes (205) are arranged in a geometric window plane (215) which is parallel to the window frame (40).

Optionally, a scale (21), for example a scale positioned at one end of the window, can be excluded from the rotary movement unless it is a fixing scale (22). This scale remains in the closed state, while the other scales (21, 22) perform their rotary movements.

The opening elements (24) can be attached by means of side scale brackets (23) or by means of the first tab of the hinges (51). If the scale material is suitable for this, the opening elements can also be attached directly to the scales (21, 22).

In the Figure 1a The illustrated outer drape (3) is a reversibly-retractable embodiment having a drape frame (31), a drape panel (32) bounded by the frame distal end (315) which is reversibly retractable together with the drape panel (32). In Figure 1a the cover surface is not visible because it is completely in the cover frame (31, Figure 3B ) attached cover box (34) is stored compacted. The terminal frame distal end (315) cannot be retracted into the cover case. It remains outside the cover box even when the cover surface (32) is in the retracted state. A complete retraction of the cover surface (32) in the cover box (34) is thus prevented. When the cover surface (32) is fully extended, the distal end of the frame (315) connects to the ends of the side frame arms (316) that are remote from the cover case. This is among other things in Figure 2B shown.

Figures 1b and 1c are schematic illustrations of a hinge (5) suitable for the embodiment shown. Other forms of suitable hinges are possible. In the example given, the hinge has a long first hinge plate (51) which is attached to a fixing scale (22) parallel to or flush with the lateral outer edge of the fixing scale. The greater length of the first hinge strap contributes to stable attachment to the fixing scales. It also contributes to better distribution of the forces acting on the fixing scales during the course of the rotary movement.

The hinge is provided with a second hinge plate (52) which in the example given is bent at right angles in a planar L-shape. The illustrated second hinge plate (52) also has a stabilizing element (521) for the angled hinge plate. The stabilizing element (521) serves to prevent undesired deformations, for example bending of the planar L-shape. The hinge straps (51, 52) can be attached to the outer cover (3) or the fixing scales (22) by means of fixing devices (524), for example screws.

The distance (d) between the outer cover (3) and the sheds (21, 22) of the shed window (2) is determined in this embodiment by the distance between the hinge axis (53) and the kink point (of the second hinge plate (52 ) certainly.

The distance (d) between the outer covering (3) and the sheds (21, 22) of the shed window (2) prevents the sheds (21, 22) and outer covering from touching. Scratching or wear and tear on the scales and/or the outer cover can thus be avoided. Differing dimensions of the individual sheds, in particular different widths of the sheds, could block the opening of the shed window if the outer cover rests on the first longitudinal edges of the wider shed during the opening process, thus preventing the outer cover from being lifted further. As used herein, width means the distance between the first longitudinal edge, defined above, and the second longitudinal edge, defined above, of a scale. The distance (d) provides some tolerance for deviation of individual flakes from the ideal identical width, or identical dimensions of the flakes. The requirements for precision in the dimensions of the flakes are therefore less stringent.

First and second hinge straps rotate about the hinge axis (53) connecting the two straps.

The shed window with cover is in figure 2 shown in its open state, figure 3 shows the closed state. The retractable cover surface (32) of the outer cover (3) with frame (31) is in Figures 2ab and 3ab fully undressed.

As seen from the side view in Figure 2a shown, the opening angle α between the scales (21, 22) and the outer covering (3) essentially corresponds to the opening angle α1 between the scales and the geometric window plane (215). The outer covering (3) is arranged parallel to the plane of the window frame (215) or the window frame (40) both in the closed and in the open state. In both said states, as well as in the transitional movement between the states, the distance (d) between the window scale (21, 22) and the frame of the outer covering (31), which is predetermined by the shape of the second hinge straps (52), remains unchanged.

As can also be seen, one of the two fixing scales (22) is in the first portion of the scale window (11) and the second fixing scale is in a second portion of the scale window (12). In the illustrated embodiment, all scales open and close simultaneously in a coordinated rotary motion. However, for example, the end scale of the second portion of the scale window (11) can be decoupled from the rotary movement and assume a permanently closed state. This optional design could, for example, offer additional protection against incoming rain or the sun's rays.

In the side views of the figures 2a and 3a the side frame arms of the outer cover (316) and the cover box (34) are cut away so that the rollable cover surface (321), the distal frame end (315) and the retractor (341) stored in the cover box are visible.

figures 2a and 3b are plan views of the shed window with cover in open, Figure 2b , and in the closed, Figure 3b , condition of the shed window. Due to the opening rotary movement of the scales, the cover is lifted and moved translationally at the same time. For this reason, when the shed window is open, the outer cover (3) assumes an offset position in relation to the frame of the shed window (40), as shown in FIG Figures 2A and 2B recognizable. A part of the frame of the shed window (40) is thus in plan view Figure 2B to see clearly. When closed, the outer covering (3) completely covers the scales (21, 22) of the window. When the shed window is in the closed state, the outer cover preferably also at least partially covers the frame of the shed window (40).

figures 4 , 5 , 6 and 7 Figure 10 illustrate a specific embodiment of the invention, namely a shed window with an outer covering installed in a pitched roof (60). An outdoor environment (200) is separated from an indoor space (100) by the pitched roof.

Figure 4a Figure 12 is a three-dimensional view of a closed shed window with outer covering installed in the roof (60) with the covering surface (32) of the outer covering removed for clarity of illustration. Figure 4b shows the same embodiment in the open state of the shed window. In this preferred embodiment, the frame of the shed window (40) is recessed into the roof (60), so that the sheds (21, 22) of the window are flush with the outer surface of the roof or its roof tiles (60). In this example, when the window is closed, the outer cover (3) is in the immediate vicinity of the outer surface of the roof. The cover box (34) can rest on the scales of the sloping window.

ln the in figure 5 The interior view of the same exemplary embodiment illustrated shows the window frame (40) recessed into the roof. Through the open scales (21, 22) of the window are Cover surface (32) and the frame of the outer cover (31) can be seen. The opening and closing of the sheds can be motorized. For this purpose, an in figure 5 shown motor (45) provided.

Figure 6b shows a cross-section of a closed shed window with the cover extended along section line (A) shown in Figure 6a is marked. The roll-up device (341) of the cover surface (32) can be seen in the cover box (34). In this embodiment, the shed window is again recessed into the roof (60), the outer cover (3) of the closed window lying in the plane of the outer surface of the roof. The outer covering of the closed window is flush with the outer surface of the roof, or the roof tile (62).

Further cross-sections of a closed shed window with external cover built into a pitched roof are in figure 7 illustrated. Various positions that the retractable cover surface (32) can assume are in Figures 7a and 7b shown. In Figure 7a the cover surface is extended to half of the window. Figure 7b shows the cover fully extended.
