Description

Fitting unit for a window or a door

The present invention relates to a fitting unit for a window or a door, with a frame on which a sash is held, the sash being movable from a closed position through at least one curved guide into a position in which it is exhibited in parallel, and the sash from the position in parallel Position is pivotable about a vertical axis in a rotational opening position.

DE 10113597 discloses a fitting unit for a window or a door, in which a sash can first be moved into an extended position, in order to then be pivoted from this extended position into a rotational opening position. Link guides are provided for parallel opening of the wing, while pivoting takes place about a vertical axis which can be moved horizontally by the length of the opening movement. The disadvantage of this fitting unit is that due to the fixed distance between the sash and the axis of rotation on the frame, the sash is not completely, i. H. can only be opened at 90 °. The opening angle can be increased slightly by appropriate contours of the frame and the wing, but this does not achieve the goal of opening by 90 ° and is also visually disadvantageous.

Furthermore, it has already been proposed in the prior art to enable a window to be opened on the one hand and to allow a rotary opening only from the closed position on the other hand. However, this construction is poorly suited for automatic opening operation, since two possible types of movement are available, which initially require a selection.

A fitting for a tilt-swivel wing with a stay scissors is also known from DE 1 086 147. The fitting can be used to tilt the window to a tilt or turn opening position. Furthermore, a parallel opening window with a rotating function is known from DE 19825071, in which a fitting element encloses an outer frame in an angular manner, a connecting link guide being provided on the fitting element itself for the parallel opening of the window. These fitting elements have the disadvantage that they are mounted on the outer frame from the outside and are therefore on the one hand visually conspicuous and on the other hand have to be carried out through seals between the sash and the outer frame. In addition, the fitting element itself acts as a cold bridge. This construction is therefore not suitable for qualitatively demanding doors or windows.

It is therefore an object of the present invention to provide a fitting unit for a window or a door, which enables parallel opening and pivoting into a rotary opening position with a large opening angle in a compact design.

This object is achieved with a fitting unit with the features of claim 1.

According to the invention, a wing is held on a frame, wherein at least one upper horizontal link and at least one lower horizontal link for guiding the wing are provided on an upper side of the wing and are arranged in the closed position of the wing within the frame , As a result, no fitting parts protrude from the sash or frame in the closed position, so that good thermal insulation and a compact design are achieved. Furthermore, a stable guidance of the wing is achieved by the horizontal link, which is movable in a rotational opening position with a large opening angle. The term “pivoting” encompasses any rotational movement, and there may also be a further relative movement of the wing with respect to an axis of rotation. Preferably, the upper and lower links are each articulated about a vertical axis on the frame, so that the corresponding fittings can be mounted on an inside of the frame. Then the upper link extends at least partially along the top of the wing, and the lower link extends at least partially along the bottom of the wing so that the links are not visible in the closed position and only when the wing is opened and pivoted in Appearance.

According to a preferred embodiment, the vertical axis runs through a space between the frame and sash. Then it is advantageous if the sash moves away from the vertical axis when swiveling in the opening direction, so that the sash does not abut against the frame and the maximum opening position is limited.

In order to move the wing somewhat away from the axis of rotation when pivoting, an additional link can be guided on the frame at least on the upper side, said link being articulated to the link. The wing can be held at least partially on the additional link so that a defined pivoting movement occurs when opening. The additional link is guided at one end to the frame and articulated on the opposite side to the handlebar, wherein the linkage is provided between an attachment point for the wing and the guide in the frame. The distance between the linkage of the handlebar and the attachment point for the wing can be used to remove the wing from the axis of rotation of the handlebar when pivoting in the opening direction and thus to achieve a larger maximum opening position than would be possible without a corresponding radial movement.

In order to avoid damage due to an excessive opening of the wing, an opening limitation is preferably provided. As a result, the hardware unit is particularly well suited for automatic operation. The opening limitation preferably has two articulated arms, whose pivotability relative to each other is limited by a stop. This allows the opening limitation to be installed in a relatively small space. Alternatively, the displacement of an additional link can be selected as an opening limitation, in which case a little more installation space is required.

According to a further embodiment of the invention, a wing lifter is attached to the frame in the region of the axis of rotation of the lower link in order to introduce the weight forces of the wing into the frame. For this purpose, the wing lifter can be angled and reach under the wing with one leg, so that a particularly stable support is provided. A second leg can be fixed on the side of the wing, in which case there is preferably a certain elasticity so that the opening movement of the wing is compensated for by a certain ner turn of the upper leg. The sash lifter can also be tilted slightly to the side, so that the sash is always held securely even with an adjustment movement.

For a particularly compact design, corner deflections can also be provided on the side of the wing opposite the vertical axis, on each of which a control curve for the parallel opening of the wing is attached.

The invention is explained in more detail below using several exemplary embodiments with reference to the accompanying drawings. Show it:

A fitting unit is mounted on a frame 1 and a wing 2, wherein the wing 2 can first be moved by the frame into a parallel position and then into a rotational opening position. For this purpose, the wing 2 is pivotable about a vertical axis 3.

For moving the wing 2, a handle 5 is provided which moves a push rod fitting 6 via a gear 4. The push rod fitting 6 is connected to an upper and a lower curve guide 8 via corner deflections 7. Another push rod fitting 9 is adjacent to the curve guide 8 Provided, which is in connection with a curve guide 10 in order to ensure a parallel opening of the wing 2 in the region of the axis of rotation 3.

In the closed position of the wing 2, the hand lever 5 is directed downwards. When swiveling over the horizontal position up to the inclined position just before the vertical position upwards, the maximum parallel position of leaf 2 is reached. If the hand lever 5 is turned further into the upward position, the wing 2 is released on the cam guides 8 and can thus be pivoted about the vertical axis 3. For this purpose, an upper opening device 11 and a lower opening device 12 are provided, which are explained in detail below.

2A and 2B, a curve guide 8 is shown. The curve guide 8 comprises a base body 13 in which a groove-shaped control curve 14 is recessed. The base body 13 is fastened to the wing 2 by means of screws 15 and mounted on a push rod fitting 9 or on the corner deflection 7. A pin 16 is fixed to the frame 1. It is also possible to connect the pin 16 to the push rod fitting 9 or the corner deflection 7 of the wing 2 and to mount the base body 13 on the frame 1.

The pin 16 moves in the cam 14, the pin 16 being arranged in the lower position when the wing 2 is closed. If the pin is moved to the position 16 ', the wing 2 is in the maximum flared position. In this position, the pin 16 ′ is arranged on an opening 17 and can leave the curve guide 8. In the position 16 ″, the pin is outside the base body 13 and the wing 2 is in a rotational opening position.

In Fig. 3 the part of the fitting unit contained at the top right in Fig. 1 is shown in plan view. To guide the wing 2, a link 20 is provided which is rotatable about the vertical axis 3. The frame 1 is shown slightly moved away from the wing 2 for a better overview, in fact a web 18 rests on wing 2 and a seal on the opposite inside

19 rests on sash 2 on frame 1. On the opposite side, the link 20 is connected via an elongated hole to a bolt 25 which is mounted in a housing 50 which is only shown in FIG. 9. The housing 50 itself is anchored in the fitting receiving groove of the wing 2 in a fixed position.

An auxiliary control arm 24 is mounted on the control arm 20 and is articulated on an axle 27 to an additional control arm 21 and on an axis 26 to the control arm 20. The additional link 21 is also articulated with an axle 28 on the housing 50, and connected to the wing 2 above it. On the opposite side, a slide 22 is provided on the additional link 21, which is movably mounted in a groove 23 on the frame 1.

For a parallel opening of the wing 2, the wing 2 is lifted off the frame 1 via the curved guides, so that the wing 2 reaches the position 2 '. In this position the handlebar is in position 20 'and the additional link in position 21'. The wing 2 'is held on the axis 28 via the curve guide 10 and via fastening means. When moving from the closed position into the open pivot position 2 ″, the wing moves away from the axis of rotation 3. This is because the wing 2 is not mounted directly on the handlebar 20, but on the axle 28 of the additional link 21.

In the closed position, there is a distance A between axis 28 and axis of rotation 3, the distance between axis 27 and axis 28 being a. In the open position, the axis 27 "is arranged closer to the axis of rotation 3 than the axis 28", the radial distance between axes 27 "and 28" being b. The distance between the axis of rotation 3 and the axis 28 "was drawn in with B. The following geometric relationship results from the articulation of the links:

B = A + a + b In other words, the wing 2 is further away from the axis of rotation 3 during the pivoting by the length a + b, so that the wing 2 with the seal 19 or a corresponding contact edge is prevented from abutting the frame 1 and the maximum opening position is limited , In the exemplary embodiment shown, the maximum opening position is reached when the slide 22 bears against a stop in the position 22 ″ and therefore no further pivoting movement of the wing 2 is possible.

In the alternative exemplary embodiment shown in FIG. 4 for an upper opening device in the region of the axis of rotation 3, an auxiliary link 24, as in FIG. 3, has been dispensed with, as a result of which there is a certain simplification. A link 20 is mounted on an axis of rotation 3 fixed to the frame 1 and is connected via an axle 29 to an additional link 21. The additional link 21 is located above a slide 22 which is held in a groove 23 on the frame 1. Furthermore, an axle 28 is provided on the additional link 21, on which the wing 2 is mounted via the housing 50. Furthermore, the wing 2 is still mounted on a curve guide, not shown, on the handlebar 20.

In order to open the wing 2, it is first brought into the position 2 'which is shown in parallel. The wing 2 is then opened and pivoted into the position 2 ″, the slide 22 being brought into the opening position 22 ″ up to a stop. The additional link 21 "then protrudes obliquely and holds the wing 2" on the axis 28 ".

5A, the opening device according to FIG. 4 is shown, but from the view of the plane of the wing 2. The link 20 is fixed on the axis of rotation 3 and connected via an axis 28 to an additional link 30, which serves as a pivot limiter. The wing 2 is held on the additional link 30 on an axis 29. Furthermore, a pin 91 is provided on the handlebar 20, which engages in a control cam 90 of a cam guide 10, which cam is displaceably mounted on the wing 2. In contrast to the curve guidance arranged on the side of the handle 5 (FIG. 2A), the control curve 90 is designed to be closed and enables the pin 91 just a sliding movement. The shape of the control curve 90 can be seen in particular from FIG. 6A.

FIG. 7 shows the upper part of the fitting unit similar to FIG. 6A, but in the maximum parallel position of the wing 2. The pin 91 is moved in the control cam 90, so that the wing 2 has moved accordingly. The push rod 9 is shown spaced apart from the curve guide 10 for reasons of clarity.

8, the opening device 12 is shown in the lower region of the wing 2. The curve guide 10 has been moved over the fixed control pin 91 and has thus brought about the parallel exhibition of the wing 2.

9, the wing 2 is shown in the open position, the opening device shown being arranged at the top of the wing 2, but also being mountable on the lower side in the same way. The link 20 "is connected via the axle 29" to an additional link 30, which also acts as a swing-out limiter. For this purpose, the additional link is constructed in two parts with a first lever 31 and a second lever 32, which are connected to one another via an axle 33, the axle 33 being held in an elongated hole 34 in the lever 31. The lever 31 is rotatably attached to the frame on an axis 36. On the lever 32, the link 20 "is fixed on the axis 29", while the wing is held on an axis 28 ".

The opening position of the wing 2 is limited in that a stop 35 is formed on the lever 31, which allows a maximum angle of the levers 31 and 32 of less than 180 °. As a result, the wing 2 cannot jam even in automatic operation. To close the wing 2, the two levers 31 and 32 are folded over one another, so that the space required for the additional link 30 and swing-out limiter is kept comparatively small. In Fig. 10, the lower opening device is shown in the view of the plane of the wing 2. A wing lifter is provided in the area of the axis of rotation 3, which engages under the wing 2 with a first horizontal leg 41 and is fixed laterally on the wing 2 with a second leg 42. The horizontal leg 41 corresponds to the handlebar 20. The upper leg 42 is fixed for this purpose via a pin 43 on an adjustment fitting 44 on the wing 2.

The wing lifter is fixed to the frame 1 via a pin 40, which forms the axis of rotation 3. In the area of the axis of rotation 3, a bearing disk 45 is provided below the sash lifter so that the weight of the sash 2 can be dissipated onto the frame 1.

The wing lifter does not have a pivot point on the frame 1 about a horizontal axis, but the lower leg 41, which also acts as a link, causes the leg 41 to twist there, the edges of which rest on the bearing plate during the parallel exhibition of the wing 2 45 supports and thereby compensates for the dimensional component that results from the tilting of the sash lifter during parallel exhibition. The wing lifter is also, starting from the adjustment fitting 44, diagonally shaped downward toward the window frame 1 and designed to introduce the weight of the wing into the window frame corner. The length of the sash lifter is selected to be relatively large, since this sash lifter must compensate for the lifting movement of the sash 2 from the frame 1 during the opening by deformation.

In the previous exemplary embodiments, a link 20 was shown, to which at least one additional link is attached in order to mount the wing 2 on the link, and thus a relative movement away from the axis of rotation 3 of the link during the pivoting of the wing 2 from the position shown To reach 20. This mechanism is stable and can be stowed away in the space between the sash and frame so that it is not visible from the outside. However, it is also possible to use the mecha- Techniques to use other mechanisms that allow the wing to pivot from the extended position.
