EP0563550A2 - Fitting for a door or window pivotable around its central axis - Google Patents

Abstract

With swinging sashes but also with reversible sashes, which are usually large sashes, the upper and lower half of the sash must be firmly tightened or pressed against the frame (1) in the closed position to ensure the necessary sealing and warping of the sash frame (2 ) to avoid. Such closures (30) can be attached and actuated in a simple manner with standard or at least almost standard elements if the fitting is designed according to the invention in the area of the pivot bearings (6) and (7). For this purpose, at least one of the rotary bearings (6, 7) has a coupling part (33) slidably mounted in the wing bearing part (8), on which a first push rod (27), which can be moved directly on the basic profile (18) of the sash frame (2), and one opposite offset to the outside, on a folding bar (20) of the casement (2) slidably mounted second push rod (32) are coupled. This bridges the fold jump or the jump in the sealing plane in a simple manner.

Description

The invention relates to a fitting for a wing rotatable about an approximately central axis, mounted on a fixed frame, in particular a window sash, with two pivot bearings, each consisting of a wing bearing part and a frame bearing part, each with at least one between the two bearings arranged, which can be actuated via a slide member that can be displaced on the wing, the slide member being coupled to a drive device on the wing. Such fittings are primarily used for swing sashes, but they can also be used with reversible sashes. Swinging wings have an im Use the horizontal bearing axis of the wing, while the bearing axis of the wing runs vertically for a reversible wing. Both types of wing have in common that one half of the wing is moved outwards when opening and the other half of the wing is moved inwards. In the case of a swing wing, the upper wing half generally moves inwards, i.e. into the room, while the lower wing half simultaneously moves outwards. Accordingly, when opening a reversible wing, for example, the right half moves into the room interior and the left half moves outwards.

The frames of such sashes are usually produced with a rollover, ie they are so-called rebated frames, which ensure tight closing. In the case of frames of windows and doors equipped with at least one rebate, the casement frame overlaps the fixed frame or frame. This poses no particular problems when opening a conventional rotating wing or tilt-and-turn wing. In the case of a swing wing or reversible wing, on the other hand, the frame construction of the wing frame and of the fixed frame is already more difficult because, as said, one wing half is turned inwards and the other is turned outwards. As a result, a changing stop is required, the change taking place in the storage area.

In the following, reference will only be made to the swinging wing, that is to say the wing which can be rotated about a horizontal axis, without this being interpreted restrictively. In such a swing wing, a so-called cover strip of the upper half of the sash frame overlaps both a folding strip of the upper half of the sash frame and the upper half of the fixed frame. Accordingly, there is a cover strip on the inside of the fixed frame, which overlaps a folding strip of the lower half of the fixed frame and against which the lower sash half strikes when the window is closed. The two folding strips are preferably produced separately with a view to rational production of the two frames and then firmly connected to the base frame of the wing on the one hand and the base frame of the frame on the other. The two base frames themselves then have the same profile throughout.

Swinging sashes as well as reversible sashes are generally large-area windows. So that they close well all around, appropriate closures must be provided for the swing wing above and below the pivot bearing. The locks must be released before opening the sash.

The folding slats placed above the pivot bearing of the swing wing cause problems with these closures. For rectangular frames, the vertical ones Locking parts mounted on the actual sash frame. Only then is the fold bar attached above this pivot bearing. An upper horizontal lock is placed on the outside, with a coupling connection being required at least for windows made of plastic or aluminum profiles. As a result, you need special parts and with profile systems you are also dependent on the respective system. The associated solutions are consequently complex and require complicated breakthroughs for the coupling connection. With round windows, these difficulties are very great due to the special shape.

It is therefore the task of further developing a fitting of the type described above in such a way that it is simple to manufacture and assemble, that special parts are avoided regardless of the shape of the frame and that complicated openings are not necessary.

To achieve this object, it is proposed according to the invention that the fitting is designed according to the preamble of claim 1 in accordance with the characterizing part of this claim. This fitting can, as the embodiment shows, easily be attached to a round window and just as well to a rectangular or other shaped window. It does not require any special breakthroughs in the frame and it also leaves the Use conventional profiles for the frame too. In this respect, this fitting can be used with all known materials, i.e. with wooden frames as well as with plastic or aluminum profiles.

Appropriately, however, at least with wooden frames, separately manufactured folding moldings will still be preferred and the cover moldings will also be manufactured separately.

The wing bearing part and the frame bearing part can be attached to the respective frame, in particular the base frame, in a very simple manner. The drive device for the push rod or push rods is located thereon, in particular at the lower wing end. Starting from this drive device, the first push rod runs along the base frame of the wing to the associated bearing. From the latter, the connection to the one or more closures is made via the second push rod, which is moved along the upper fold strip of the wing. The push rods are therefore also offset in the case of a round window, the second push rod being located further out in the radial direction than the first push rod. The same applies of course to the rectangular or a differently shaped frame. The offset corresponds approximately to the thickness of the rebate strip - in the case of a round window - in the radial direction. After mounting the two bearing halves on each side of the bearing the or each coupling part is connected to the first and second push rods. All closures can thus be actuated with the help of the drive device in an opening and closing sense. The wing is hooked into the two frame bearing halves in a known manner. As the exemplary embodiment shows, it is usually sufficient if only one of the two bearings is equipped with a coupling part and the push rods do not extend over the entire circumference of the wing.

A further development of the invention provides that the wing bearing part and the frame bearing part each have a fastening plate which can be inserted into a receptacle of the associated base frame. The recess will expediently be chosen so that the base plate used is flush with the material around the recess. The attachment is carried out in a known manner, for example by screwing.

A further embodiment of the invention results from claim 3. It creates the necessary offset in the transverse direction or in the radial direction for the second push rod in relation to the first push rod. If the bearing plate thickening is molded directly onto the mounting plate, this leads to particularly inexpensive manufacture.

A particularly preferred embodiment of the invention can be found in claim 4. If you let the sash bearing part in the manner described there in the base frame of the wing, so is the first fitting groove on the sash strip of the sash with correct attachment of the first fitting groove automatically as an extension of that first fitting part groove of the wing bearing part.

Another embodiment of the invention is described in claim 5. With the correct dimensioning of the second fitting groove and correct assembly of the wing bearing part, it ensures an exact alignment of the second fitting groove with the second fitting part groove of the wing bearing part.

The bearing-side end of the first push rod is overlapped in a very advantageous manner on the wing bearing part by a holding plate. In this regard, a further development of the invention results from claim 7. The pins mentioned there are preferably located on the wing bearing part, and they can be formed directly, which of course reduces the manufacturing costs. For safety reasons it is better to fix the bearing plate with at least two screws. These can advantageously also be fastening screws for the wing bearing part.

The bearing end of the faceplate of the second Push rod advantageously engages under a web of the wing bearing part, whereby it is secured against lifting or lifting. In this area, a sealing element can be attached, which ensures the necessary sealing on the bearing.

A further embodiment of the invention results from claim 11. The ends of the two L-legs of the coupling part pointing towards the fixed frame advantageously extend outside to approximately the free end of the wing bearing part. In order to prevent lifting out of the guide of the wing bearing part and, above all, to improve the stability, the guide can be overlapped at a suitable point by means of a web or the like, as a result of which a breakthrough occurs at this point.

According to a preferred embodiment of the invention, a coupling element for a push rod end is located on each L-leg of the coupling part, the latter being provided with a coupling counter element. The coupling is preferably carried out according to claim 13. The teeth described there are known in principle. Coupling takes place transversely to the longitudinal axis and plane of the connecting rod end. In addition, the coupling part is mounted in a very advantageous manner by guide webs free of play in receptacles of the wing bearing part or the fitting part grooves.

The first push rod is slidably mounted in a second fitting groove of the wing base profile. The groove cross-section of the wing base profile and the rebate strip are rectangular in a known manner and widened like a shoulder at their outer end, the longitudinal edges of faceplates resting on these shoulders. The latter is fastened in a known manner with the aid of screws which pass through elongated holes in the push rod and are screwed into the material of the latter in the case of wooden frames. The same applies to the plastic and metal frames.

The closures and the drive device for the push rod or push rods can be carried out in a known manner.

In the exemplary embodiment, as stated, the fixed frame 1 and the sash 2 are each circular, but this is not a requirement for the fitting according to the invention. The sash can be pivoted about a central geometric axis 3, which runs in the horizontal direction in the embodiment and built-in window. As a result, it is a swing wing. The upper half in FIG. 1 moves inward when opening, while the lower wing half is consequently pivoted outwards. As a result, there is a change in the sealing plane and also with respect to the approximately semicircular cover strips 4 and 5 indicated in FIGS. 2 and 3.

The sash frame 2 is rotatably mounted on the fixed frame 1, also called a frame, by means of two pivot bearings 6 and 7. According to FIG. 2, each consists of a wing bearing part 8 and a frame bearing part 9 (FIG. 2). In the exemplary embodiment is located on the wing bearing part 8 a bearing pin 10 which engages in a bearing bore 11 of a bearing arm 12 when the wing is suspended. The hanging can be done in a known manner and is no different with a round window than with a rectangular or generally speaking polygonal.

Each of the two bearing parts has a fastening plate 13 and 14, respectively. The fastening plate 13 of the frame bearing part 9 is flush-mounted on the outside in a cutout or receptacle 15 of the fixed frame 1 or more precisely the base profile 16 of the fixed frame 1. A receptacle 17 of the sash 2 or the base profile 18 of the latter receives the mounting plate 14 of the wing bearing part 8 flush on the outside. With a view to cheap production, the fixed frame 1 and the sash frame 2 are expediently each produced from a base frame and a folding strip 19 or 20. In addition, the cover strip 5 and 4 is attached at the end. When producing the two frames from metal or plastic profiles, the frame can be manufactured in a different but known manner.

The mounting plate 13 of the frame bearing part 9 is made in one piece with a plate thickening 21. Accordingly, there is a thickening 21 on the fastening plate 14 of the wing bearing part 8. The bearing eye 12 is integral with the whole, on the one hand, and on the other hand the bearing eye 23 of the wing bearing part 8 manufactured. It remains to be added that the folding strip 20 can also be made in one piece with the basic profile 18 and the folding strip 19 in one piece with the basic profile 16 or the lower cover strip 5.

At the lower end of the casement 2 there is a drive device 24 with a gear 25 which can be actuated by means of a handle which can be inserted into a square bore 26 of the gear. Rotation of the handle causes a first push rod 27 to be displaced. In the exemplary embodiment, a locking pin or, more generally, a locking element 28 is attached to both sides of the drive device. Opposite is a striking plate 29 on the fixed frame 1, each of which together forms a closure 30. The displacement movement of the first push rod 27 in the sense of the double arrow 31 is transmitted to a second push rod 32 in the embodiment in the right-hand pivot bearing 7 in the manner explained in detail below , on which in the exemplary embodiment there are also two locking pins or locking elements 28 of two further locks 30 for the upper wing end.

Between the first push rod 27 and the second push rod 32 is according to the inventive design of the rotary bearing 6 or 7, a coupling part 33 is switched. Its exact shape and configuration can be seen in FIG. 4. The coupling part 33 is slidably mounted in the wing bearing part 8 in the sense of the double arrow 31. It can be seen in particular from FIG. 3 that the second push rod 32 is mounted displaceably in a first fitting groove 34 which is open at the edge towards the fold, U-shaped in cross-section but enlarged on the outside on both sides. A second fitting groove 35 is attached to the basic profile 16 of the casement 2. It picks up the first push rod 27. A cover rail 36 covering this is supported on the shoulder-like groove widenings 37 and 38. The same applies to the faceplate 39, which overlaps the second push rod 32.

From the foregoing it follows that the first push rod 27 and the second push rod 32 are offset from one another in the radial direction in the round window, the offset corresponding approximately to the width of the folding strip 20 of the casement 2, measured in the radial direction. Furthermore, it can be seen from FIG. 2 that the closure elements 28 attached to the push rods penetrate corresponding elongated holes 40 of the two faceplate rails to the outside. The striking plates 29 have slots on the side open to the edge. About this, the closure elements 28 occur when closing the wing. If one now operates the drive device 24 in the predetermined direction of rotation, then the Closure elements 28 moved in the striking plates 29, whereby they engage behind a corresponding web and can thereby cause the sash frame 2 to be tightened to the fixed frame 1 and prevent the closed sash from pivoting.

According to, for example, FIG. 3, there is a first fitting part groove 41 on the plate thickening 22 of the sash bearing part 8, which groove runs in alignment with the extension of the first fitting groove 34 of the sash frame 2 or the folding strip 20. Accordingly, a second fitting part groove 42 is attached to the mounting plate 14 of the wing bearing part 8, in which the L-leg 43 of the coupling part 33 is slidably mounted and is flush with the outside. The first fitting part groove 41 is, due to the length of the other L-leg 44 of the coupling part 33, of course seen in the radial direction, much deeper and the two merge directly into one another. Because at the inner end of the first fitting part groove 41 there is a cross plate 45 of the wing bearing part 8 which serves for stiffening, an opening 46 is made at the transition from the first fitting part groove 41 to the second fitting part groove 42. The L-leg 43 extends through this the coupling part 33 is pushed into the wing bearing part 8 in the direction of arrow 47 (FIG. 3). It can only be removed in the opposite direction.

On each L-leg 43 or 44 of the coupling part 33 there is a coupling element 48 or 49, in particular molded on, for the associated push rod end. Accordingly, a coupling counter element 50 or 51 is attached to each push rod end. The coupling elements 48 and 49 are, according to, for example, FIG. 4, a U-shaped toothed slide in cross section with two opposing longitudinal teeth 52 and 53 or 54 and 55.

It can be seen from FIG. 2 that the bearing-side end of the faceplate 39 of the second push rod 32 engages under a web 60 of the wing bearing part 8 and is thereby held in place. A sealing element 61 is attached below this web. When the wing 2 is closed, a corresponding edge of the frame bearing part 9 bears against it and thus effects the sealing in the bearing area.

As can be seen particularly well in FIG. 2, the bearing-side end of the first push rod 27 on the wing bearing part 8 is gripped over and held down by a holding plate 62. Two dowel pins 63 and 64 ensure the necessary centering. They engage in bores 65 and 66 of the holding plate 62. In the exemplary embodiment, the latter are fastened with the aid of two screws 67 and 68, which penetrate countersunk bores 69 and 70 of the holding plate 62. In extension of that are on the mounting plate 14 of the wing bearing part 8 holes 71 and 72 through which the screw ends penetrate into the material of the wing frame.

From the drawing (Figure 1) on the one hand and indirectly from the description it follows that the push rods 27 and 32 must of course be curved in a round window. In the case of a rectangular window, for example, straight push rods can be used, however, corresponding deflections are then required in the corners. In any case, the use of standard locking parts is possible. The locking parts of a round wing should preferably follow the curve. Both the push rod ends and the faceplate ends can be shortened to the necessary extent, it being easily possible to cut both in one operation. The tooth-like attachments can easily bridge manufacturing tolerances.
