Description

The invention relates to a fitting for a turning window and a turning window with such a fitting. This fitting is provided for a turning window with a frame and a window frame which can be turned relative to the frame, wherein the turning window for turning the window sash has its first end from a closing position of the sash at a first end of the frame to an open position from the first end of the frame along the Sliding frame is slidably mounted, and the sash is at least approximately carried in equilibrium with a pair of scissors.

State of the art:

From the NO 107 278 B a fitting according to the preamble of independent claim 1 for such a turning window is known. This known fitting for a turning window of the type mentioned includes a guide rail formed on the frame, a guided by the guide rail from the closed position at a first end of the guide rail to the open position sliding part with which one end of the sash about a slidable along the guide rail sliding axis pivotally hinged to the guide rail, and a two-legged scissors. The first leg of the scissors is formed by an arm which is articulated about a balance axis on the window sash. The second leg is formed by two rectified pivot lever, which are articulated on the arm about two spaced hinge axes and the frame around two spaced pivot axes.

The guide rail extends on the inside of the pivot point of the pivot lever over the entire height of the frame. The arm is about half as long as the first pivot lever. The second pivot lever is about half as long as the arm. In the closed or turned position, the two pivot levers lie one behind the other in the longitudinal direction. The distance between the two hinge axes is greater than the length of the second pivot lever. Both the pivot levers from the hinge axes to their hinge axes, as well as the arm from the hinge axes to the balance axis, extending in the direction of the turning position of the sliding part.

Such fittings have the advantage that they are supplied very compactly between the window frame and window frame with the window closed. When opening and closing the window, the balance axis is held practically at a constant height, so that the window sash only has to be pivoted and pushed outwards. This causes the operation of the window sash requires little effort and the sash can be made reversible. Such a fitting allows the turning of the window by 180 degrees.

This fitting has been further developed. In Norwegian patent application no. NO 2,180 / 70 a fitting of the same type is shown, in which the arm and the first pivot lever are about the same length. Both pivot levers are in a known manner in a common plane perpendicular to the window plane, but against the NO 107 278 B not in the longitudinal direction one behind the other, but rather next to each other. They are fastened with a common mounting plate on the frame and extend in the closed position of the window over a substantial part of their length parallel to each other.

However, these fittings have the disadvantage that they can not meet today's requirements regarding the tightness of windows. When opening the sash, its upper half enters between the two shears. As a result, it is impossible to provide the window laterally projecting fold on the window, which could fit sealingly on the frame. The fitting must therefore lie on the opening side of a seal between the sash and the frame.

From the EP-A 0 542 050 a turn window and a window fitting according to the preambles of the independent claims is known. In the scissors of this fitting, both the pivot levers extend from the hinge axes to their pivot axes on the frame and the arm from the hinge axes to the balance axis on the window sash in the direction of the closing position of the sliding part. The first pivot lever is stretched. The second and end hinged on the arm pivot lever is slightly bent. When opening, the sash moves away from the frame to one side as the scissors opens and lowers the sliding part in the rail. The articulation axes lie on this one side of the rail. The rail passes on the other side past the pivot axes. The scissors are therefore completely between the rail and the Casement. The bend of the second pivot lever is used to arrange the two pivot levers in a common plane.

A disadvantage of this window fitting and turning window is that the outwardly opening window sash can not strike the outside with a fold from the outside of the frame, as such Falzüberstand impossible on the scissors and the pivot axes can be passed over.

The fitting further has the disadvantage that the window sash is brought with its upper edge when closing only from below and parallel to the plane of the frame to the frame. It is therefore not possible to press the wing circumferentially from the outside to the frame. But this complicates or prevents such a seal of the wing with respect to the frame, which meets today's requirements.

Object of the invention:

• It is therefore an object of the invention to provide a window fitting, which makes it possible to issue a window sash with little effort around a horizontal turning axis or to turn. Tasks of preferred
  Embodiments of the invention, the fitting and the turning window with the fitting in such a way that the sash can be sealed when closing all around in two spaced levels relative to the frame, and that a seal of the sash over the frame done by pressing perpendicular to the window plane can.

Description of the invention:

This object is achieved according to the invention in a fitting according to the preamble of claim 1, or in a turning window according to the preamble of claim 24,
by the features of claim 1 or claim 24.

This means that opposite the fitting according to the NO 107 278 B the scissors is reversely aligned, ie, that there formed as a support arm arm according to the invention is a support arm. The first, upper pivot lever is conveniently articulated between the hinge axis of the second pivot lever and the balance axis on the arm, and the second, lower pivot lever is hinged terminally on the arm. When opening the window sash approaches the lowering upper end of the hinged to the frame ends of the pivot lever. This end of the first pivot lever is the first part of the fitting, which reaches the other side of the pivoting window plane. Only these articulated on the frame ends of the pivot lever reach the in the closed state to the outside directed side of this pivoting opening window level. All other parts of the fitting remain on the same side of the window level during any manipulation of the sash. This grants a great deal of freedom with regard to the lateral design of the window sash. The window sash can thus extend laterally beyond the fitting, for example with the glass, and be designed to abut against the window frame.

The scissors described allows to expose the window sash with little effort and to support the center of gravity of the sash, while the upper end of the sash slides from top to bottom, or from bottom to top.

When lowering the first end of the window sash to the attachment points of the fitting on the frame over pass necessarily Parts of the fitting on the other side of the window level. These parts, namely the articulated on the frame ends of the pivot lever, but are outside the edge of the window when the guide rail between the two legs of the scissors extends into it. It is therefore the first end of the window sash, or the sliding part, thanks to this arrangement of the guide rail, are guided past the pivot axis of the first pivot lever, without coming into conflict with these pivot axes. This design has the disadvantage over the arrangement of the guide rail on the side remote from the window sash of the fitting that the window can not be turned completely. However, it has the advantage that a fold can be formed on the window sash, with which the sash can also rest on the wing side of the fitting on the frame sealing. As a result, the fitting can be arranged within a sealing point.

In this case, the first pivot lever arcuate or sickle-shaped. The crescent shape allows the sliding part to release the longest possible sliding path between the legs of the scissors. This sickle shape thus allows the window to be turned up to about 165 degrees. This is especially important for cleaning the outside of the window.

A compact collapsible scissors with a large effective range is made possible by the shape of the pivot lever and the position of the pivot axes and the hinge axes is selected such that the first pivot lever at a change between the closed position and the open position of the fitting on the pivot axis of the second pivot lever on the frame has to be swung away.

The second pivot lever is expediently shorter than the first pivot lever. The first pivot lever is preferably at most half as long as the arm. The second pivot lever is conveniently longer than one third of the arm. With an appropriate arrangement of the axes of the distance between the pivot axes (articulation of the pivot lever on the frame) is greater than the distance between the joint axes (joint between pivot levers and arm).

For a compact solution of the fitting expediently both pivot levers are arc-shaped. Thanks to this shape, these pivoting levers can grip around the first end of the turned sash or around the sliding part. This not only allows the sash to approach 180 degrees Turn, but also on the sash surrounding, therefore also on the first side of the sash to form a fold, which strikes in the closed position outside the fitting on the frame. Advantageously, the first pivot lever is formed arcuate in such a way that the angle at which the pivot lever adjoins the extended arm is greater than the angle between the arm and a line connecting the hinge axis and the pivot axis of the first pivot lever.

For easy installation, the arm with the balance axis is hinged to a mounting plate. The mounting plate may e.g. be attached to the sash with screws.

Although the two pivot levers could ever be attached to a separate mounting plate, or directly on the frame, it is preferred if the two pivot levers are articulated to a common mounting plate. This can be attached to the frame and defines the exact geometry of the scissors.

Conveniently, the sliding part is designed as a lever. Are then at a first end of the guide rail means for forcibly pivoting the pushed against the closing position lever in or from a pressed against the frame sealing position available, it has the advantage that the edge of the sash against this first end of the guide rail against the frame can be pressed by the lever is pivoted. In the closed position of the frame is practically only in the longitudinal direction of the guide rail in the final position. In the sealing position, the frame is additionally pressed transversely to the guide rail against the frame from the closed position.

This lever also has the advantage that the first end of the window sash when opening the wing is pivoted away from the frame and is guided at a distance from the guide rail. As a result, this wing may have a projection with respect to the pivot point of the sliding axis on the window sash. This supernatant allows the formation of a fold, which can strike from the outside against the frame. This projection is kept at a distance from the frame thanks to the lever. So that the first end of the wing can be guided with the supernatant from the outside against the frame, it is required that this lever is pivoted to an end position. For this purpose, means are provided which forcibly cause this pivoting.

Conveniently, the lever is stirred at a certain angle to the guide rail standing along the guide rail. Thus, the first end of the sash is guided in a certain, constant distance from the frame. If the lever can also be designed to be pivotable relative to the guide rail, then it is preferred that it is at a certain angle to the guide rail. This prevents the lever from being pivoted unintentionally and ensures that the distance of the sash from the sash is virtually constant regardless of the position of the opened window.

The means for forcibly pivoting the lever may be formed by an arcuate portion of the guide rail. Then the lever relative to the guide rail need not be designed to be pivotable. When the lever is at a certain angle to the guide rail, it is forcibly pivoted when passing through the arc section.

However, the lever may also be formed pivotable relative to the guide rail at least at the first end of the guide rail. Then, the means for forcibly pivoting the lever are conveniently formed by a cooperating with the lever stop which pivots the lever. Over the remaining length of the guide rail, the lever can still be guided against the guide rail non-pivoting therein. There may be two guides in the guide rail, which hold the lever position stable and which cause a pivoting of the lever in an end position.

The lever may have an elongate guide head. Advantageously, the lever has two guide heads cooperating with the guide rail. This gives him a defined orientation to the guide rail. Thanks to spaced contact points between the guide heads or the guide rail and the lever is guided at a certain angle to the guide rail. He can therefore absorb forces from the wing and ablate on the guide rail and is not pivoted by these forces. The guide rail is expediently designed stretched between its end regions. However, the upper end region is preferably formed as an arc section.

To form the means for pivoting the lever, an end part is advantageously arranged subsequently to the first end of the guide rail. At this end part, the means for pivoting the lever are formed and can be mounted in a simple manner on the frame or on the guide rail. In addition, this means the means for pivoting the lever are very easy to arrange precisely at the right place on the window frame.

For a turning window two such fittings are conveniently used in mirror image execution.

The invention also relates to a turning window with a fitting described above. Such a turning window has in a known manner a window frame and a relative to the frame about a horizontal axis exhibitable or reversible window sash. The first end of the window sash is displaceably mounted for turning the window sash from a closing position at a first end of the window frame into an open position away from the first end of the window frame. Such a shift happens along the frame. The window sash is also worn with scissors at least approximately in equilibrium.

This turning window is equipped with a fitting. This fitting comprises a guide rail attached to the frame, a sliding part guided through the guide rail from the closed position to the open position, and a two-legged pair of scissors. The sliding part is articulated about a sliding axis pivotally mounted at one end of the window sash. In the scissors of the first leg is formed by an arm which is articulated with a Balancesachse the casement. The second leg is formed by two rectified pivot lever. These pivot levers are articulated on the arm about two spaced hinge axes and at spaced locations about two pivot axes on the frame. The first pivot lever is conveniently articulated between the hinge axis of the second pivot lever and the balance axis on the arm, and the second pivot lever is advantageously articulated terminal on the arm. The window according to the invention differs from the prior art described above in that, in this turning window, both the pivot levers extend from the joint axes towards their pivot axes and the arm from the joint axes toward the balance axis toward the closing position of the sliding part. This arrangement of the scissors, which is the reverse of the prior art, has the above-mentioned advantages with regard to freedom of the lateral design of the window sash.

The guide rail is advantageously passed on the side of the window sash on the pivot axes. The hinge axis about which the second pivot lever and the arm are hinged to each other at their ends, as far as possible moved to the edge, so that the sliding part can be moved as far along the guide rail. The pivot axes of the pivot lever are arranged as low as possible. The pivot axes are advantageously arranged in the bottom third of the window height.

The arcuate shape of the pivoting lever also increases the sliding range for the sliding part far to the opposite of the first end of the guide rail edge of the window frame. If the first pivot lever is of arcuate design and if a slot is formed in the frame, the convexly formed region of the pivot lever can be arranged in this slot in the closed state of the turning window. This slot allows to arrange the pivot lever beyond an inner sealing plane between the sash and the frame, without affecting the tightness of the window. Even the pivot axis of the second pivot lever is advantageously arranged within the slot, so that the geometry of the scissors is optimally formed, and the depth of the window frame (the dimension perpendicular to the window plane) can be kept as low as possible.

This window formation allows that the sash and the frame both in two spaced planes have circumferential sealing strips, and that these sealing strips in the closed position abut each other, or can be pressed against each other in a sealing position. An elastic sealing lip may be provided on the frame or on the window sash.

In the closing position of such a turning window with two sealing levels of the fitting is a total of a gap space between the circumferential Arranged sealing strip. It is not only protected against dirt, but also forms no significant thermal bridges.

The fitting is advantageously arranged on a profile which forms a wing-side region of the frame. This profile is advantageous for thermal reasons, a plastic profile.

The guide rail is advantageously formed directly in the profile. It can be excluded in an end region and supplemented by an end part, which defines, for example, an arc section.

The frame expediently comprises a frame made of wooden rods. At each of the frame forming wooden rods a cut piece of the profile is placed outside. This profile survives the wooden stick on the window wing side. For a simple attachment of the profile on the wooden rod, the wooden rod has at least one groove and the profile at least one engaging in this groove rib.

The window sash is advantageously formed from the outside to the frame with a circumferential sealing strip abutting. This sealing strip is advantageously outside the attachment points of the fitting on the frame and the window sash. On the window sash can be formed to a fold. However, in a preferred embodiment, the sash has a frame and step glazing projecting laterally beyond the frame. The fold and the outer sealing strip is thus formed by the outer glass of the stepped glazing.

Thus, the profile does not have to have a cutout for the pivot axes, the mounting plate for the pivot lever is bent with advantage such that the mounting plate is lifted in the region of the pivot axes from the ground.

In a fitting with a described guide rail and a displaceably mounted therein lever, on which the upper end of a turning window wing is to be articulated, a pair of scissors is formed, which has the following features. The support arm carries at its outer end a mounting plate which can be attached to the casement. He is certainly equipped to be hinged to the sash. The support arm is therefore hinged directly to the sash frame at the turning window.

In order for the end of the support arm articulated or to be hinged on the window wing to execute a substantially rectilinear and advantageously horizontally aligned movement during pivoting of the support arm, the support arm is equipped with two pivot levers articulated on the support arm, which in turn are articulated or hinged to the window frame. These pivoting levers do not intersect. The four pivoting axes (two articulated axes and two articulation axes) form a quadrilateral which can be varied during pivoting and whose side lengths remain constant. However, the angles between opposite sides change, thanks to which the side lengths of the four sides are different in length.

In similar known fittings, the joints between the pivot levers and the extension arm are up, while the pivot points are on the frame and the sash below. In the case of the scissors according to the invention, however, the pivot levers of the pivot axes arranged in the lower third of the frame, formed between the frame and the pivot levers pivot down to the hinge axes formed between the support arm and the pivot levers. Accordingly, the support arm does not fall outward, but the support arm extends from the lower hinge axes up to the higher end of the support arm, which supports the sash. As a result, this pair of scissors does not conflict with the vertically displaceable lever on which the upper end of the sash is articulated.

Conveniently, the lower pivot lever is shorter than the upper pivot lever. Further, in order to obtain the desired movement of the support arm, the distance between the two formed between the frame and the pivoting levers pivot axes is greater than the distance between the two formed between the support arm and the pivot levers pivot axes.

Thus, the sash can be turned as far as possible, the pivot lever to the window inside are convexly arcuate. You can therefore embrace the upper end of a turned window sash.

A pair of scissors to support a sash has, like known scissors, a support arm for supporting the sash, a first near one end the pivoting arm (and closer to the window sash than the second) hinged and hinged to a frame pivoting lever. In addition, a second articulated at this end of the support arm and articulated to the frame pivot lever is present. Of known scissors, the one described here differs in that the first pivot lever are at most half as long as the support arm. Thanks to these length ratios, the scissors is reversed than the known mounted in the frame, without the pivot lever must cross the sliding path of the sliding part after a short sliding distance. The scissors are therefore to be mounted in a V-shaped upwards opening on the frame. Thanks to the length ratios, the scissors are articulated in the lower third of the frame. This allows the turning window at least to turn so far until the upper end of the window sash passes into the lower third of the window frame. The scissors also allows the sash to protrude laterally from the scissors, because when turning and closing the sash against the frame, the support arm and the swivel arms always remain on the inside of such a protruding window sash rebate.

Advantageously, the first pivot lever is formed arcuate in such a way that the angle at which the pivot lever adjoins the support arm is greater than the angle between the support arm and a straight line connecting the pivot axes of the pivot lever. As a result, the upper end of the window sash can be moved far beyond the pivot axis of the first pivot lever arranged on the window frame. The arcuate pivot lever engages around this upper end of the window sash.

The second pivot lever is expediently shorter than the first pivot lever, but longer than one third of the support arm. This results in an approximately horizontal movement of the outer end of the support arm, which is well above the Schenkachsen the pivot lever.

In a turning window with a frame and a reversible window sash is known, the sash is slidably mounted at an upper end in a vertically guided along the frame guide rail. The sash is carried with scissors. The scissors comprises two pivoted on two pivot axes on the frame pivot lever and hinged to the pivot levers support arm. The support arm is articulated in a central area on the window sash.

In contrast to known turning windows, the guide rail in the proposed turning window on the side of the window sash is guided past the swivel axes arranged on the window frame and is designed to open in a V shape upwards. Thanks to this design, the upper part of the sash can be moved past the pivot axes in the opening of the V-shaped open scissors into it. The pivot lever, or at least the closer to the sash pivot lever is arcuate. Thus, the opening of the V-shaped fitting is enlarged so that the upper end of the window sash can be lowered even further. This arcuate design of the pivot lever requires that the pivot lever takes up more space than between the frame and window sash is present. Therefore, a slot is formed in the frame, in which in the closed state of the window, the convex portion of the window sash nearer, arc-shaped pivot lever is arranged.

Detailed description of the figures:

In the FIGS. 1 to 4 an embodiment of a turning window 11 is shown with a fitting according to the invention. The figures show the frame 15 cut, so that the structure of the frame of the wooden rod 23 and the drawing board 25 is visible. The view is directed to the inside of the opposite reveal of the frame 15. On this inside of the Leibungsbrettes 25, a pair of scissors 41 and the guide rail 31 is arranged.

Further, the sash 17 is visible, with sash 27 and glass 19. The sash 17 is shown in different figures in the figures. FIG. 1 shows the window sash in a horizontal position in which the support arm 39 has the largest projection. FIG. 2 shows the window sash 17 in an extreme turning position, that is, the window outside is turned inwards. FIG. 3 shows the sash in slightly open position (ventilation position). FIG. 4 shows the sash in the closed position.

The sash 27 is supported by a pair of scissors 41. The turning window fitting 13 comprises a guide rail 31 and displaceably mounted on two rollers 33 a lever 35 (FIG. Fig. 1 ). At this lever 35, the first (upper) end of the window frame is pivotally mounted about a sliding sliding axis 51. The guide rail 31 has at its first (upper) end an end portion 45 with an arc portion 47 and then an elongated vertical portion 49 along the outer edge of the Leibungsbrettes 25th

The scissors 41 has an arm designed as a support arm 39, which is articulated with a first (outer) end on a mounting plate 43 arranged on the casement frame 27. The mounting plate 43 is slightly above the. Middle, that is arranged in a lower portion of the upper half of the window on the window sash. The second end of the support arm 39 is the frame side connected via two spaced-apart pivot lever 61, 63 with the frame 15. The first pivot lever 61 is articulated above the second pivot lever 63 on the frame 15 and at a short distance from the second end of the support arm 39. The second (lower) pivot lever 63 is within the wooden rod 23 of the frame 15, i. hinged behind the plane defined by the sealing strip 65 on the wooden rod 23 on the frame 15, with which sealing strip 65 of the sash 27 in the sealing position of the sash circumferentially sealingly abuts the wooden rod 23 of the window frame.

The two pivot levers 61, 63 are arcuate, so that the sash 17 can be turned up to the maximum ( Fig. 2 ). The inventive fitting allows to pivot the window by about 165 degrees. The bow-shaped or crescent-shaped design of the pivot lever requires that, when the window is closed, the pivot levers lie largely within the plane defined by the sealing strip 65 arranged on the wooden rod ( Fig. 4 ).

A slotted in the wooden rod 23 slot 67 provides the necessary space for the pivot lever 61, 63 in the closing and sealing position.

For a secure anchoring of the pivot lever 61, 63 on the frame, a mounting plate 69 is present, which is connected to the Leibbrettbrett 25 and on which the bearings are designed for the pivot lever. The two pivot levers 61, 63 overlap each other. The lower pivot lever 63 is closer to the paving board 25 and the upper pivot lever 61 is closer to the wing frame ( FIGS. 1 to 3 ). The two pivot levers 61, 63 are articulated on opposite sides of the support arm 39 so that they pivot in spaced-apart planes.

The distance between the pivot axes 71, 73 of the pivot lever 61, 63 on the frame is greater than the distance between the hinge axes 75, 77 of the pivot lever 61, 63 on the support arm 39. In addition, the lower pivot lever 63 is shorter than the upper pivot lever 61. This is a pivoting of the pivot lever 61, 63 outwardly connected to an opening of the angle between the frame 15 and the support arm 39. The balance axis 55 between the support arm 39 and casement 27 moves during pivoting of the pivot lever 61, 63 practically horizontally outward.

When opening the window 11, the support arm 39 is pivoted outwardly, wherein the two pivot levers 61, 63 with pivot. As a result, the lower end of the support arm 39 is raised and the angle between the support arm 39 on the one hand and the pivoting levers 61, 63 on the other hand becomes increasingly larger. The maximum opening angle of the support arm is achieved in the horizontal position of the sash. The opening angle between the support arm and window sash (depending on the height of the window and the choice of fitting size) is approximately 35 degrees. When pivoting the sash in the horizontal position, the pivot lever 61, 63 pivot about 55 degrees (first pivot lever 61) and about 70 degrees (second pivot lever 63).

In a further lowering of the upper end of the sash 17 of the support arm 39 is pivoted back until finally the window sash is turned and with the outside of the glass at a small angle of about 15 degrees in front of the opening of the frame 15. In the closed position, the support arm 39 is parallel to the frame 15.

The upper end of the window sash 17 is articulated on the lever 35, which lever is slidably mounted in the rail 31. With the pivoting of the window sash and the lever 35 is pivoted by the positive guidance of the curved portion 47 of the rail 31 to the outside. The window sash 17 is first lifted off the sealing strips 65 before the upper end of the window sash is guided vertically downwards through the stretched section 49 of the rail 31.

The scissors 41 can basically be housed within the frame profile in the space between the frame 15 and the sash 27. The frame profile is formed from the wooden rod 23 and the bracing board 25.

At the in FIG. 5 illustrated embodiment, in contrast to the first embodiment instead of the soffit board 25 provided a profile made of plastic. In this profile 25, the guide rail 31 is already formed. Therefore, in this embodiment, the fitting also includes this profile 25. The fitting 13 forms in this embodiment, therefore, also a part of the frame 15. The profile 25 may be made of plastic, to have an advantageous thermal insulation value. It may, for example, be extruded from aluminum. However, extruded plastic profiles are also cost-effective in the production and already proven in window construction.

The profile 25 is glued to the wooden rod 23. The frame profile is formed from the wooden rod 23 and the profile 25th

In both embodiments, a double seal is achieved. The seal of the sash 17 relative to the frame 15 also takes place by pressing the wing 17 against the frame 15 in a direction perpendicular to the window plane and the sealing planes.

An inner sealing plane is defined by the sealing strip 65 on the wooden rod 23 of the window frame. An outer sealing plane is defined by the sealing strip 65 on the profile or on the paving board 25. In sealing position of the window frame 27 presses against the inner sealing strip 65 and the inside of the outer glass of the step glass 19 against the end face of the profile or the Leibungsbrettes 25. This end face is formed at least in the profile 25 substantially by the guide rail 31.

Between the two sealing strips 65 is a space in which the entire fitting is arranged. However, this space is extended with the slot 67 behind the inner sealing level in the wooden rod 23 inside.

An elastic seal is expediently provided in the region of the inner sealing strip on the frame. A second elastic seal may be provided on the inside of the projecting stepped glass 19. These seals can also be formed on the respective opposite part, namely on the inside of the window frame 27 and on the front side of the reveal board 25 or the profile 25th
