Description

The invention relates to fittings and bearings for windows or doors, in particular guide / Ausstellscheren for parallel issuing window or door wings against a frame.

In the field of windows and doors consisting of a frame and a wing, in particular parallel-opening windows, fittings are used in order to be able to support the wing with respect to the frame at a defined distance and / or angle. In the case of parallel opening windows, a wing arranged in a window frame can in many cases only be arranged laterally offset parallel to the frame when opening, so that the wing is only connected to the frame via fittings and no longer bears against one of the frame sides. An additional angular arrangement can only be provided when a plurality of fittings are used, namely at least four fittings, and on each fitting further, the distance between the frame and wing is freely adjustable. Then, at two of the four fittings, a first distance and at the other two of the four fittings, a second distance can be adjusted, and the wing is arranged at an angle to the frame. Apart from the elaborate setting but usually arise stability problems.

Ausstelischeren or guide shears as a special form of fittings are used to keep windows in a tilted position and in most cases to move from a closed position to the tilted position and vice versa. They usually have both functions. Hereinafter The term guide shears is used, as it emphasizes that a guide when opening or closing the windows is desired. Guide shears can be provided laterally on the window frame and / or on the horizontally extending upper window frame part. Basically, two types can be distinguished, namely three-point guide shears and four-point guide shears. Both types each have two scissor arms, which are coupled together. In three-point guide shears usually two of the three bearing points are rotatably mounted and one rotatable and displaceable. Optionally, two bearing points are rotatably and slidably mounted. The scissor arms are coupled together in a bearing, which in addition to a rotation and a translational relative movement allows each other, for example, a slot. In four-point guide shears usually two of the four bearing points are rotatably mounted and the other two rotatable and displaceable. The scissor arms are coupled together in a bearing, which only allows rotation to each other.

The publication EP 2 228 509 A1 shows a display device for a window or a door and has a stay, which is pivotally mounted on a tilting wing about a horizontal axis parallel to the wing.

The publication DE 100 31 820 A1 shows a tilting device for a tilting wing and has a stay arm, which is pivotally mounted on a frame and a wing about a vertical axis, wherein in a tilted position both pivot axes are inclined from the vertical position.

The publication DE 10 2008 032 750 B4 shows a Parallelausstellfenster which supports a window sash over a plurality of fittings, each with a lever arm and a support arm and an X-scissors with a pair of scissor arms on a window frame, the scissor arms are rotatably mounted respectively in two bearings on the sash and the window frame and one of the bearings also allows axial displacement. Each scissor arm is slidable on one side and fixed on one side between the sash and the frame.

The task is to provide a simply constructed guide shears for a wide range of applications.

These objects are achieved by a four-point guide shears according to claim 1 and a bearing device according to claim 7 and by a guide system according to claim 11. Advantageous developments of the invention are explained in the subclaims.

A four-point guide shears according to the invention for constructed from a frame and a wing parallel-Ausstellfenster or doors has a first scissor arm and a second scissor arm, which are each rotatably storable in two arranged on the frame and the wing bearings and each in one of the camp are additionally axially displaceable storable. According to the invention, at least one pivot bearing is provided on each of the scissor arms, via which the scissor arms are pivotably mountable.

A four-point guide shears thus has scissor arms, each with at least one bearing, in which in addition to a rotational movement, a pivoting movement and optionally also a translational movement can take place. In other words, the pivot bearings are bearings with three degrees of freedom. Preferably, a pivot bearing is designed as a radial sliding bearing on each scissor arm, which additionally allows a rotational movement of the scissor arm relative to the pivot bearing.

In each case two pivot bearings are preferably provided on the scissor arms, by means of which the scissor arms are pivotally mountable in each case in both bearings, i. over which both free ends of the scissor arms are pivotally storable. Optionally, it may be sufficient in certain cases to provide only two of the four free ends of the scissor arms pivot bearing.

Such a parallel Ausstellmechanimus with four-point guide scissors can also be used in folding windows or doors. The Parallel Ausstellmechanimus can allow a variety of different arrangements of a wing over a frame. An inventive Four-point guide scissors with pivot bearings is also designed to exhibit a wing of a parallel-Ausstellfensters or a parallel-issuing door at an angle relative to the frame, wherein the wing with respect to the frame can be pivoted upwards or upwards. At the same time a good lateral stability can be ensured in a flared wing, in particular by the lateral support is carried out substantially solely by the cross-shaped scissor arms in a symmetrical manner on wings and frame and in relatively widely spaced bearing points. Also, an opening limitation on the guide shears can be done, in particular by the pivot bearings are arranged between bearing blocks on which they can strike when they are arranged in a desired position corresponding to the desired maximum open position. It can also provide an opening angle limitation, in particular by providing a stop on the pivot bearings which strikes against a corresponding stop when pivoting has taken place by a certain angle.

The scissor arms of a four-point guide scissors according to the invention are not only one-sided displaceable and fixed on one side fixed to the frame and wings, but are also pivotable, in particular about a bearing axis on which the scissor arms are also mounted axially displaceable.

As a pivoting movement is preferably to be understood a rotational movement, which takes place about an axis which is aligned horizontally in an arrangement of four-point guide scissors on a horizontally oriented side of a wing or frame, so that the four-point guide shear against the Wing or frame can pivot, even if the distance between the wing and frame remains constant. That is, according to the invention, the pivot bearings may be rotatable, e.g. allow about an axis along which usually two of the four free ends of the four-point guide shears are displaced.

As a rotational movement is to be understood preferably a rotary movement, which takes place about an axis in an arrangement of the four-point guide shears on a horizontally oriented side of a Wing or frame is oriented substantially vertically, so that the four-point guide shear can rotate relative to the wing or frame to change the distance between the wing and frame. That is, the pivot bearings allow the four-point guide shears per se required relative rotation between the scissor arms and the bearing points.

In other words, according to the present invention, there is provided a four-point guide shear, with which the wing can be arranged in a variety of different positions relative to the frame, and at the same time a high stability of the flared wing and a good ruggedness of the bearings or the whole deployment mechanism can be ensured , Although the guide shear according to the invention can combine several functions in itself, it is simple. In particular, it may be constructed symmetrically, wherein the plane of symmetry passes through a scissors joint, via which the two scissor arms are coupled together.

A guide scissors according to the invention can be used for parallel-lowering opening window and for parallel lifting-Ausstellfenster. It can also be used for countersunk folding windows and lifting / tilting windows. This results in a wide field of application.

According to one embodiment, the pivot bearings are adapted to be pivotally mounted about a bearing axis. The pivot bearings may each have a passage, which is designed to be arranged around a bearing axis and guided by the bearing axis. The implementation may be designed as a cylindrical bore, in particular as a bore, which is introduced into a solid part of the pivot bearing. It can optionally also be formed by a tube which is connected to one or two side plates, in which a bolt may be provided for coupling the scissor arm to the pivot bearing. The implementation can be designed as a smooth slide bearing from a smooth running plain bearing material with a low coefficient of friction.

The pivot bearings may optionally have one or two side plates, via which they are coupled to the respective scissor arm. Two

Side plates have the advantage of a more stable guidance and a better bearing of a bolt.

According to an embodiment, which may be based on one of the embodiments described above, both scissor arms each have two pivot bearings, wherein each scissor arm one of the pivot bearing is designed as a fixed pivot bearing and the other of the pivot bearing as a sliding pivot bearing. In this case, the pivot bearings can also be designed to rotatably support the scissor arms. In this way, in a pivot bearing, the storage about a rotational axis, the storage about a pivot axis and the storage along a translational axis take place.

As a fixed pivot bearing or fixed pivot bearing is preferably a pivot bearing to understand, which can be fixed to a bearing axis. As a sliding pivot bearing is preferably a pivot bearing to understand, which can be moved along which it is pivotable along a bearing axis.

The fixed pivot bearings may be formed as fixed pivot bearings in that they have locking means over which they are e.g. ascertainable on a bearing axis in a certain position, i. can be fixed.

Preferably, the displaceable pivot bearings are slidably formed on the bearing axis, by which they are also pivotable. This can be realized via pivot bearings, which have a passage for the bearing axis and a sandwich-like slot guide, wherein the slot guide are provided to guide the free ends of the scissor arms laterally and support. As a result, a simple and robust construction can be provided. The passage can be arranged in a kind of sleeve, and on the sleeve can protrude two side plates, between which a free end of a scissor arm can be performed. In this case, the pivot bearing may have a rectangular base surface in a plan view, and describe in a side view a U-shaped outer contour, wherein the legs of the U correspond to the two side plates and the rounding of the U of the outer surface of the sleeve.

Characterized in that the pivot bearings are adapted to rotatably support the scissor arms, a simple construction is provided, in which the storage of the scissor arms can take place via a single interface to the frame or wing, namely a coupling which can cooperate with the bearing axis. The rotational movement can be carried out relatively between the respective scissor arm and the associated pivot bearings. An advantage of this design is not only the simple structure, but also the ability to decouple the scissor arms alone on the pivot bearing of the pivot bearings and the bearing axes. This facilitates assembly or disassembly.

According to an embodiment, which may be based on one of the embodiments described above, at least one of the displaceable pivot bearing is adjustable braked in the direction of displacement is executed. The displacement direction preferably corresponds to an orientation of a bearing axis on which the pivot bearings can be mounted. In other words, a pivot bearing, which is braked in the direction of displacement or completely blocked, be converted from a radial sliding bearing in a radial-axial bearing (Radiaxiager), which also allows the rotation between the pivot bearing and scissor arm (degree of freedom 2 instead of 3).

The displaceable pivot bearings may have as a braking means, for example, a screw with a flat bottom or a wedge displaceable in the direction of a bearing axis, and the braking means can be adjusted on the one hand with regard to a preferred friction between the pivot bearing and the bearing axis, on the other hand as a fixation in serve a certain position and thus the determination of a certain distance or angle of the wing relative to the frame. The displaceable pivot bearings may also have an additional bushing, which can be pressed by a braking means to the bearing axis.

By adjustable braked pivot bearing a wing can be stored insensitive to wind. A hitting the wing in the wind can be easily prevented and adapted to the local weather conditions. It is e.g. possible to store the wing stably in any position relative to the frame stable.

According to an embodiment, which may be based on one of the previously described embodiments, the fixed pivot bearings have locking means for fixing the fixed pivot bearings to a bearing axle.

By way of the locking means, the fixed pivot bearings may be e.g. be fixable on a bearing axis. The locking means can be designed as guided in an internal thread on the respective fixed pivot bearing locking screws which are screwed into the bearing axis, or they can be designed as connected to the respective fixed pivot bearing clamping rings.

According to an embodiment, which may be based on one of the embodiments described above, the pivot bearings are each coupled via a bolt to the scissor arms, wherein the bolt is formed as a rotation axis about which the pivot bearings are rotatably storable. This allows a simple and robust coupling between scissor arms, pivot bearings and frame or wing done.

As mentioned, at least one of the aforementioned objects is also achieved by a bearing device according to claim 7. The bearing device is designed for parallel-opening windows or doors with a frame and a wing designed to rotatably support a first scissor arm and a second scissor arm and axially slidably support one of the scissor arms, wherein the bearing device has a bearing axis, which is formed , Two pivot bearings pivotally mounted about the bearing axis and one of the pivot bearings axially displaceable on the bearing axis. The bearing device may also provide the pivot bearings themselves, if the pivot bearings are not already provided on scissor arms of a guide shear.

As a bearing axis is preferably an element or a component to understand, which can be arranged parallel to the surface of a frame or wing and serves to store both scissor arms on the frame or the wing. A bearing axis may e.g. designed as a tube or rod made of solid material, in particular of a material having a smooth surface with a low coefficient of friction. The bearing axis can also be integrated into a rail or a part, in particular structural part, of the frame or wing. Preferably, the bearing axis is designed as a pipe or rod and mounted in three bearing blocks, particularly preferably continuously in a middle bearing block and in blind holes in bearing blocks at their free ends.

According to one embodiment, the bearing axis may be mounted on a bearing block, which is fixedly connected to the frame or the wing. The bracket may be glued or screwed to the frame or wing or fastened at an angle or strap. Preferably, the bearing block on two through holes, so that the bearing block in a simple manner rotatably mounted on the frame or wing can be mounted and the bearing axis in a certain orientation.

According to an embodiment, which may be based on one of the embodiments described above, the bearing axis is mounted on three bearing blocks, wherein two of the three bearing blocks are arranged at free ends of the bearing axis and the other bearing block in a position on the bearing axis, in which the wing in a maximum open position is arranged to the frame when a pivot bearing comes to bear on the bearing block.

According to an embodiment, which may be based on one of the embodiments described above, the bearing block has a passage in which the bearing axis is mounted. Preferably, the passageway is disposed on a side of the bearing block which faces away from scissor arms to connect the sash to the frame when mounted on the sash or frame. This allows the bearing block itself to a large extent as a stop surface for slidable pivot bearings are used, and a pulse from the pivot bearings can be distributed flat and passed over a wider area in the frame or wing. As a result, a simple and robust construction is possible.

As mentioned, at least one of the aforementioned objects is also achieved by a guide system according to claim 11, namely a guide system for guiding parallel opening windows or doors constructed from a frame and a wing, wherein it is preferably proposed that two be at least approximately identical in construction and at least approximately symmetrically arranged bearing devices according to the invention are provided, which are coupled to a four-point guide scissors according to the invention.

According to one embodiment, the displaceable pivot bearings are each mounted between two bearing blocks of the bearing device. The bearing blocks may each have a stop or a stop surface against which the sliding pivot bearing can strike when the wing is opened or closed. About the pedestals can thus define the maximum opening of the wing and also the position of the wing on the frame in which the wing is to be closed with the frame. This can avoid that wing and frame hard hit each other when the operation is careless or the wing is detected by a gust of wind. The stop or the abutment surface can be designed for this purpose optionally made of a damping or soft material, at least in one layer on the bearing block. This is useful even if the frame, e.g. made of a soft wood, to avoid that the bearing blocks are beaten from their brackets over time.

According to an embodiment, which may be based on one of the embodiments described above, the bearing blocks are arranged so that the sliding pivot bearings abut the bearing blocks when the wing is opposite the frame in a closed position or in a maximum open position. Preferably, bushings for the bearing axis are provided on the bearing blocks, and indeed a side facing away from the window or door opening, ie outside the guide system.

According to an embodiment, which can be based on one of the embodiments described above, two bearing devices according to the invention are provided with three bearing blocks, wherein the bearing blocks each having a passage, which are arranged on a side facing away from the scissor arms of the guide shears side of the bearing blocks, and wherein the Implementation relative to a base of the bearing blocks, with which the bearing blocks are mounted on the wing or frame, is arranged elevated and at each bearing device, the pivot bearings are pivotable in both directions about the bearing axis.

As a result, the guide system can be used both in parallel lowering and parallel lifting-Ausstellfenstern or doors. Due to the spaced arrangements of the bearing axes of the wing or frame, the pivot bearings can pivot in a large angular range about the bearing axes, without colliding with the wing or frame. Depending on the dimension of the pivot bearings and the distance between the bearing axes, the maximum possible pivoting angle can be in the range of 10 to 60 degrees, preferably 20 to 50 degrees, more preferably 30 to 40 degrees. A swivel angle over 45 degrees is not required in many cases, so that the arrangement of the bearing axis and the bearing blocks and the design of the pivot bearing, for. also with regard to an inconspicuous arrangement or a low height or a small footprint can be done.

In this case, the entire guide system can be constructed symmetrically, wherein the plane of symmetry passes through a scissor joint, via which the two scissor arms of the four-point guide shears are coupled together. The symmetry can be given regardless of the arrangement of the wing relative to the frame. The plane of symmetry extends in the open by pivoted wing through the scissors joint and is also inclined relative to the frame or wing by the same extent as the scissor arms, so that the scissor arms perpendicular to the Stay aligned with the symmetry plane. The symmetry can be given at least in relation to the bearing axis and the arrangement of the bearing blocks and the pivot bearings. Due to the symmetrical structure, for example, the advantage of a simple assembly. Also, the total number of different components is very low, which allows a cost-effective production, especially due to higher number of pieces of each part.

In the following drawing figures, the invention will be described in more detail.

In the Fig. 1 a parallel-Ausstellfenster or a parallel-issuing door with a frame 2 and a wing 3 is shown, wherein the wing 3 is arranged at a distance from the frame 2 and is mounted on the frame 2 via a guide shears 30. On the frame 2, a first bearing device 10 with a first bearing axis 11 and three bearing blocks 12, each with a stop 12a, here in the form of one of the side surfaces of the bearing blocks 12, and a respective passage 12b for performing the bearing axis 11 is provided. On the wing 3 is analogously provided a corresponding second bearing device 20 with a second bearing axis 21 and three bearing blocks 22, each with a stop 22a, analogously in the form of one of the side surfaces of the bearing blocks 22, and a respective passage 22b for performing the bearing axis 21.

The bearing blocks 12, 22 can be designed as shown in two parts, in particular from an upper part with a standard height, which may be designed in relation to the diameter of the bearing axis 11, 21, and a lower part with variable height, over which the distance of the Bearing axis of the surface of the wing or frame can be adjusted, depending on the extent to which a pivoting movement is desired. As a result, the required space for the entire mechanism space can be minimized. The bearing blocks 12, 22 may also be constructed in one piece, in particular with a standard height, regardless of whether the passage 12b, 22b for the bearing axis 11, 21 in the respective bearing block 12, 22 in a standard height or in a variable Height can be arranged.

The guide shears 30 is coupled via four pivot bearings 31, 32, 33, 34 to the bearing devices 10, 20, in particular to each bearing device 10, 20 respectively via a first and second fixed pivot bearings 31, 32 and a first and second sliding pivot bearing 33rd , 34. On the fixed pivot bearings 31, 32 are each locking means 31 a, 32 a for fixing the fixed pivot bearings 31, 32 provided on the bearing shafts 11, 21, and at The displaceable pivot bearings 33, 34 are respectively braking means 33a, 34a for adjusting a frictional force or braking force between the displaceable pivot bearings 33, 34 and the bearing shafts 11, 21. The displaceable pivot bearings 33, 34 are along the respective bearing axis 11, 21 in the direction of slidable respective double arrow, ie back and forth, and via the braking means 33a, 34a they can be made adjustable braked executed. The pivot bearings 31, 32, 33, 34 are provided at free ends of scissor arms 35, 36 of the guide shears 30, which are coupled to one another via a scissors joint 38. In the pivot bearings 31, 32, 33, 34 each have a passage 39 is provided, through which the bearing axis 11, 21 can be performed so that the pivot bearings 31, 32, 33, 34 in a simple and robust manner along the bearing axes 11, 21st can be performed. The scissor arms 35, 36 are mounted relative to the pivot bearings 31, 32, 33, 34 rotatably about a z-axis, in particular via a bolt 37, which is guided or held by side plates of the pivot bearings 31, 32, 33, 34.

The pivot bearings 31, 32, 33, 34 are expediently designed in a direction perpendicular to the bearing shafts 11, 21 with a width that is greater than a width of the bearing blocks 12, 22. As width is in particular the extension of the pivot bearing 31, 32, 33, 34 and bearing blocks 12, 22 between a side facing the scissors hinge 38 side of the pivot bearings 31, 32, 33, 34 and bearing blocks 12, 22 and the respective passage 12b, 22b, 39 for the bearing axis 11, 21 to understand , In other words, the width of the extension is perpendicular to the bearing axis 11, 12. This allows the scissor arms 35, 36 are brought in a closed position of the guide shears 30 to the middle bearing blocks 12, 22 for conditioning. In particular, the pivot bearings or bolts 37 of the pivot bearings 31, 32, 33, 34 are arranged at a distance from the respective bearing axis 11, 21, which is greater than the distance between a scissors joint 38 at least half the width of the scissor arms 35, 36 facing side of the bearing blocks 12, 22 and the bearing axis 11, 21st

The passage 12b, 22b in the middle bearing blocks 12, 22 is in each case preferably designed as a cylindrical through-passage, in particular as a through-bore, so that a single bearing axis all three bearing blocks can connect to each other and the middle bracket 12, 22 along the bearing axis during assembly can be freely positioned. In this way, the maximum permitted by the guide scissors 30 opening of the wing 3 relative to the frame 2 in a flexible and simple manner can also be determined by an end user. The entire assembly of the guide system 40 is extremely simple, since only the bearing blocks 12, 22 mounted on frame 2 and wing 3, in particular screwed, must be, in particular after the respective bearing axis 11, 21 through the bushings 12 b, 22 b of the bearing blocks 12, 22nd was guided and the pivot bearings 31, 32, 33, 34 were provided between the bearing blocks 12, 22. The scissor arms 35, 36 may already be coupled to the pivot bearings 31, 32, 33, 34 or after assembly of the bearing blocks 12, 22 on frame 2 and wing 3 with the pivot bearings 31, 32, 33, 34 coupled, in particular in each case via the bolt 37, which may for example have its own safety pin or can be secured by a conventional cotter pin on the pivot bearings 31, 32, 33, 34.

The guide shears 30 and the bearing devices 10, 20 can together form a guide system 40, which is formed symmetrically with respect to a plane of symmetry S extending through the scissors joint 38. It should be mentioned that in Fig. 1 Strictly speaking, the position of the displaceable pivot bearings 33, 34 would have to be shown further away from the right bearing block of each bearing axis and closer to the middle bearing block of each bearing axis, because the middle bearing block is that bearing block on which the displaceable pivot bearings 33, 34 in an open position to rest can or should come.

In the FIG. 2 are essentially the ones in FIG. 1 already shown components in a slight modification and shown schematically, also to better illustrate the arrangement of the sliding pivot bearings 33, 34 with respect to the bearing blocks 12, 22. The guide shears 40 is as in FIG. 1 shown in a half-open position, in which the wing 3 is not yet arranged in a maximum open position, in particular because the pivot bearings 33, 34 are not yet applied to the middle bearing blocks 12, 22. The Fig. 3a shows the guide shear 30 decoupled from storage devices. On the guide shears 30, the pivot bearings 31, 32, 33, 34 are provided, which can each be coupled to an axis of bearing devices before a complete guide system is mounted on a frame or wing.

The Fig. 3b shows the storage device 10 decoupled from a guide scissors. The axis 11 is guided in bushings 12b through the bearing blocks 12, which have for this purpose bushings 12b, which may be performed in the outer bearing blocks 12, for example, as blind holes.
