Description

The invention relates to a fitting with a support arm or an extension arm for the storage of a rotating wing or a tilt and turn sash of a window, a door or the same as in the preamble of claim 1 specified.

A fitting of this type with an extension arm for storage a tilt and turn sash is for example from EP 0 421 904 B1 known. It consists of one on the frame fastening swivel bearing, one swiveling with the wing and lockable connected extension arm, and one Extension arm with bearing bracket connecting the swivel bearing, the horizontal leg with a guide Adjustment device for the end of the extension arm forms. The adjustment device enables an adjustment of the effective length of the extension arm, e.g. a sagging To be able to notify window sashes. To the fitting on To be able to switch right or left stop is the Bearing bracket on the pivot bearing around a horizontal axis rotatably mounted and in two offset by 180 ° Rotational positions through interacting projections and Recesses can be determined. To engage and disengage them Projections and recesses is one with one in the pivot bearing Tool for rotating eccentric provided. Such a Fitting with extension arm is used for the storage of a Tilt & Turn wing together with one at the bottom corner of the Wing provided corner bearing used, which in essentially absorbs the sash weight and rotary movements around the vertical axis and tilting movements around the horizontal axis allows.

Swing blades that can only be rotated around a vertical axis of rotation, but are not tiltable, are usually in ordinary hinge straps. It is also known, fittings for turn-tilt windows constructively so modify that they can also be used to store rotary sashes can be used. This has two main advantages. First, the number of items to be manufactured and in stock different fitting parts to be held reduced, if the same fittings are optional for storage a tilt and turn wing or a swing wing can be. On the other hand, it is with two-winged Windows with a turn-tilt sash and a turn sash advantageous if both wings with the same training and Hardware components mounted in the same place can be, so that there is a symmetrical Appearance results.

It is therefore known to have a fitting with a raising arm, e.g. as described in EP 0 421 904 B1, thereby for the Storage of a rotating wing to adjust that the extension arm is replaced by a so-called "false scissor arm", i.e. a support arm, which with the rotating wing on its upper horizontal fold surface is rigidly connected. With one out the example known in practice is that in the upper one horizontal rebate area of the wing above the rebate surface support arm with a groove in the rebate surface fastened faceplate screwed in several places, the faceplate additionally through to the Groove bottom of the rebate surface, extending foot pieces on Wing is anchored 'to improve stability.

When adapting one for a turn-tilt wing provided fitting with extension arm for storage There are various problems with a rotary wing Objectives. One of these problems affects the Tilt-and-turn sashes are usually available vertical adjustment of the sash relative to the frame. For this purpose, the lower corner bearing is vertical adjustable. The extension arm of the turn-tilt fitting can make such vertical adjustment movements follow, because in the him with the faceplate of the wing connecting pivot pin sufficient bearing play available is. In the case of a rotating wing that does not have an extension arm, but with a support arm to be rigidly attached to the wing is stored, this bearing clearance is eliminated and thus the Adjustability. It would therefore be desirable to support the arm like this to design that he also vertical adjustment movements allows for a rotary wing, without this Stability of the connection between support arm and wing, in particular for recording perpendicular to Forces acting on the wing plane are impaired.

It has proven to be meaningful, both the support arm as well as the swivel bearing on the frame side connecting parts so that the bearing side End of the arm sufficient for adjustment purposes has vertical freedom of movement relative to the casement, nevertheless adequately supported and guided on the wing is to all in a horizontal direction, even across To be able to absorb wing components acting on the wing plane. The aim of Guiding and supporting the elements serving as a support arm be designed to use the same fitting for the storage of a turn and tilt sash, the support arm against an extension arm is exchanged, do not hinder.

In addition, the fitting is said to relate to its Manufacturing and its operation can be simplified. For the hardware should be designed in a rational manner be that all parts are made exclusively by bending, Stamping and pressing processes can be produced and no parts to be manufactured separately by casting become. The operational simplification should be in primarily on the right-left change of the fitting Respectively. This takes place in the known fitting according to EP 0 421 904 B1 by actuating an eccentric, what a Tool, e.g. an Allen key is required. The Fitting according to the invention is intended without the aid of a Tool can be changed without this the security and stability of its establishment in the one position or another is impaired.

The invention provides for solving the problems set a fitting as in claim 1 is marked. The sub-claims relate to further advantageous configurations of the fitting.

In the exemplary embodiments, a can optionally Extension arm for the storage of a turn and tilt sash or a Support arm can be used to support a rotating wing, the bracket is flexible enough to be vertical Adjusting movements of the sash relative to the frame in can follow the same way as one Extension arm due to the bearing play in the bearing journal is possible. The stability and resilience of the Connection of the support arm with the wing is thereby ensures that additional, in the rebate groove of the wing engaging guide means are provided which Guide the support arm in a vertical direction. These leadership tools are designed so that they only work together with the Bracket are present and can be omitted if instead of a support arm, an extension arm for a turn-tilt sash is used. In this case it is Groove surface free from those that engage in it Guide parts and can, as is the case with a turn and tilt sash is required, e.g. a corner redirection of a Espagnolette fitting for locking or unlocking of the extension arm.

In the two-leaf window shown in Fig. 1 is the left wing 1 a turn-tilt wing and the right Wing 3 is a rotary wing. The turn-tilt wing 1 is in usual way through a bottom turn-tilt corner bearing and an upper scissor stay 7 with scissor bearings 8 and has a common one for locking and opening Espagnolette gear (not shown) that with a Handle 10 can be operated. The handle can be in three positions are moved, the closed position, the Tilt opening for tilting about the horizontal tilt axis A1, and the rotary opening for rotating about the vertical axis of rotation A2 correspond. The opening scissors have one on the swiveling Part of the leg bearing 8 attached arm 7. The Extension arm 7 runs concealed in the horizontal folding space of the tilt and turn sash 1 at a distance above the upper one Folded surface and can be achieved by locking elements that with the Handle 10 are operated with the wing-side Fitting rigidly locked or for pivoting movement for the Tilt opening are released.

The rotary wing 3 is only about a vertical axis of rotation A3 rotatable. However, it is also stored on the frame with a lower corner bearing 5 in combination with a upper pivot bearing 9 and a support arm 11 (also "wrong Scissor arm "). The corner bearing 5 of the rotary wing 3 can a turn-tilt corner bearing of the same type as corner bearing 6 of the turn-tilt wing 1, so that only for both wings a type of corner bearing manufactured and kept in stock must become. Alternatively, the corner bearing 5 of the rotary wing also a pure pivot bearing with a degree of freedom of rotation only by vertical axis A3.

In the corner bearings 5, 6 is in itself. known way a vertical and horizontal adjustment possible to adjust the sash relative to the frame. The setting ranges are indicated with B1 and B2 and can each be several mm.

The upper pivot bearing 9 of the rotary wing 3 is the same Design like the scissor stay 8 of the tilt and turn wing 1. Es is designed according to the invention so that it can be optionally an extension arm 7 for a turn-tilt wing or a Support arm 11 can be attached to a rotary wing.

A first embodiment of the support arm 11 and its Connection to the pivot bearing 9 is in FIGS. 2 to 8 shown. The support arm 11 has a bearing side Section 13 and a wing-side section 15, the connected to each other by a cranked section 16 are so that they are on different levels. The Support arm 11 of the illustrated embodiment is for Use determined with a sash 3, the Folding surface 19 has a groove surface groove, which, as in 4, two inwardly projecting ribs 21a has the groove in an upper groove part 22 for receiving a faceplate (if available) and a lower one Divide groove part 24 to accommodate a drive rod. The wing-side section 15 of the support arm 11 is so trained that he puts in the faceplate groove 22 and then approximately flush with the fold surface 19 of the Sash frame 3 is, as in Fig. 4 in section shown. At its end is the wing-side section 15 U-shaped bent, and the bent part 23 has one smaller width, the width and depth of this U-shaped bent part 23 are dimensioned so that this between engage the webs 21a in the lower groove part 24 and can lay down on the bottom of the drive rod 24. Using fastening screws (not shown), the through openings 25 of the support arm 11 in the Leaf frame 3 are screwed in, the leaf side Section 15 of the support arm 11 rigidly fixed to the wing. The wing-side section 15 preferably extends about 75 - 80% of the total length of the support arm 11 Sash frame 3 is in Fig. 4 as an example Plastic frame shown, the fitting according to the invention can of course also be used on wooden frames, Aluminum frames and composite frames can be mounted.

The bearing-side section 13 of the support arm 11 forms over part of its length with a guide portion 27 reduced width. This includes itself leg 29 bent downward at right angles to the its lower end 29a again to the same width as the wing-side section 15 of the support arm 11 widened is i.e. one of the width of the faceplate groove 22 of the Casement has the appropriate width.

The pivot bearing 9 has a fixed bearing part 31 which on Frame 3 can be fastened by means of screws 33 and two projecting bearing eyes 35 for receiving one vertical axis pin 37. On the fixed bearing part 31 is a movable bearing part 39, consisting of a bearing sleeve 41 which surrounds the axle pin 37 and via a connecting web 43 with a right-angled bearing plate 45 bent at the rear (in FIGS. 2 and 6) (Fig. 5) related.

The connection of the support arm 11 with the movable Bearing part 39 of the pivot bearing 9 takes place via a Bearing bracket 51, the vertical leg 53 the Bearing plate 45 of the movable bearing part 39 engages behind and attached to it in a manner yet to be explained is. The horizontal leg 57 of the bearing bracket 51 forms an upwardly open U-shaped guide 59 in which the Guide section 27 of the support arm 11 in the longitudinal direction is slidably guided. Adjacent to the U guide 59 the horizontal leg 57 of the bearing bracket 51 has one Opening 58 through which the bent at right angles Leg 29 of the support arm 11 extends. In this leg 29 is a threaded bore 61 formed in the Bearing bracket 51 used bracket 11 with a Passage opening 63 in the vertical leg 53 of the Bearing angle 51 is aligned. An adjustment screw 65 can through the passage opening 63 into the Threaded bore 61 of the support arm 11 are screwed in and serves the support arm 11 relative to the bearing bracket 51 and to adjust relative to the pivot bearing 9. To this In this way, the sash 3 can be relative to the frame 1 in horizontal direction, e.g. one to adjust the sagged sash frame.

The guide section 27 of the support arm 11 has at its top edges prism-like beveled surfaces 27a. 5, from the inside overlapped upper edges of the U-guide 59, see above that the support arm 11 in the U-guide 59 of the bearing bracket 51st is captively secured. The threaded bore 61 can have been threaded beforehand. Preferably but it is a simple hole in which the Thread through the self-tapping screw trained adjusting screw 65 is cut.

The support arm 11 is made of flat wire material exclusively formed by bending, pressing and punching. At the The vertical leg 29 can be bent by a suitable tool to ensure that the Inside a material thickening 61a forms the length the bore in which the adjusting screw 65 is mounted, to enlarge. The bearing bracket 61 is shaped so that he from flat material exclusively by bending, punching and Press operations can be made.

As mentioned, the lower corner bearing 5 of the rotary wing 3 the possibility of vertical adjustment with the in Fig. 1 indicated adjustment range B1. To this To be able to follow attitudes must also in the area of upper pivot bearing 9 and the support arm 11 corresponding vertical game be given. in the Swivel bearing 9 is not a vertical, vertical game given. The column apparently shown in Fig. 2 between the bearing sleeve 41 and the bearing eyes 35 are in in practice thanks to friction-reducing washers made of brass or filled in plastic. Therefore, according to the invention game required for vertical adjustment in the Support arm 11 provided, namely by the flexibility of Support arm 11, especially in the area of the cranking 16 as well as between this and the closest Attachment point on the casement is given. hereby can the bearing-side section 13 relative to the part of the wing-side rigidly attached to the wing Move section 15 in the perpendicular direction until it can follow the adjustment movements. The end 29a of the right-angled angle 29 is slidable in the guided vertical groove 22 of the casement 3, so that the bearing-side section 13 of the support arm 11 on Sash frame against those acting perpendicular to the sash plane Forces are adequately supported and fixed without its movement in the vertical direction is hindered.

In the following, the mounting of the bearing bracket 51 the bearing plate 45 of the movable bearing part 39 described, reference being made to FIGS. 6, 7 and 8 becomes. The vertical leg 53 of the bearing bracket 51 is in an.sich known way stored on the bearing plate 45 so that it rotated around a horizontal axis 67 and in two around 180 ° rotated positions can be locked. This serves to change the fitting to the right or left stop. 8A, the mounting plate 45 and the vertical leg lying flat against its back 53 of the bearing bracket 51 together by a rivet pin 69 rotatable, but permanently connected. The rivet pin 69 has several stepped diameters, namely a head 69a, a middle portion 69b and a rivet end 69c. He will together with one surrounding its middle part 69b elastomeric spring ring 71 in correspondingly graded Bearing openings 73, 74 of the vertical leg 53 of the Bearing bracket 51 and the mounting plate 45 introduced and set by swaging its rivet end 69c. The bearing opening 73 of the vertical leg 53 is oversized opposite the head 69a of the rivet pin 69, so that the vertical leg 53 of the bearing bracket 51 relative to Bearing plate 45 in the direction transverse to axis 67, in particular can be moved upwards, the spring ring 71st is elastically deformed as shown in Fig. 8B.

To determine the bearing angle 51 in one or other of his operating positions offset by 180 ° for Right or left stop indicates the bearing plate 45 a snap notch on each of its upper and lower narrow sides 75 into which one of two snap-in projections 77 can snap into place on the inside of the vertical Leg 53 of the bearing bracket 61 protrude. Everyone Snap notch 75 of mounting plate 45 is one rising guideway 79 upstream. When turning the Bearing angle 51 about the axis 67 is in Locking projection 77 lying in the front in the direction of movement the guideway 79 guided so that he a Transverse displacement of the bearing angle 51 relative to Fastening plate 45 with elastic deformation of the Spring washers 71, as indicated in Fig. 8B, until the respective snap-in projection 77 into the snap-in notch 75 the elastic restoring force of the spring ring 71 engages, the spring ring 71 through its restoring force the parts in the position concentric to the axis of rotation 67 according to FIG. 8 resets. To release the lock, the user must Hand a force to shift the bearing bracket 51 exert relative to the mounting plate 45 to the Lift the locking projection 77 out of the locking notch 75. Then the parts can be rotated until the each other snap projection 77 to the other Guideway 79 runs up and then in the described Locks into the other notch 75. To this Way is the right and left change of the fitting in easiest and without the use of a tool possible.

In the described embodiment, the Snap projections 77, as shown, hook-shaped trained so that they also from the leg 53 of the Bearing bracket 51 facing away from the bearing plate 45 engage behind. This will force the transmission between the bearing bracket 51 and the movable bearing part 39 of the Improved pivot bearing in the direction parallel to axis 67.

The fitting according to the invention is designed so that the Support arm 11 (wrong scissor arm) for a swing wing against an extension arm (scissor arm) for a turn and tilt sash can be replaced without affecting the rest Components of the fitting any changes must be made.

Fig. 9 shows an illustration similar to Fig. 2, wherein however, the support arm 11 of Fig. 2 by a conventional Extension arm 7 of a turn-tilt fitting is replaced. This differs from the support arm 11 in that it over its entire length above the folded surface 19 of the Casement runs and a pivot 83, which in a slot of the faceplate (not shown) of the Wing is guided, and has a locking cam 85, the one with a locking pin (not shown) wing-side fitting interacts with the opening arm 7 optionally fixed for the rotary opening on the sash or relative to the tilt opening for pivotal movement to release the wing. The facing the pivot bearing 9 End of the arm 7 is completely analogous to that based on Fig. 2 to 7 support arm 11 formed, with the only difference that the 7 leg 87 bent downwards at right angles, in which the threaded hole 61 for the engagement of the adjusting screw 63 is so short that it is not in the groove of the Sash 3 protrudes. Intervention of the bent Leg 87 in the groove of the casement would Release of the extension arm. Prevent 7 for the tilt opening and also attaching cuff rails, Corner drives or the like in the groove of the Casement in the area of the bearing-side upper corner to make impossible.

In this way, all parts of the fitting, with Exception of the support arm 11 or extension arm 7, without any Change for a rotating wing or a rotating and tilting wing be used so that the manufacture, warehousing and processing of the fitting is considerably simplified.

A second embodiment of the invention is based on the Figures 10 to 14 described. It differs from the previously described embodiment in the Design of the bearing bracket 51, both what its Connection to the support arm 11 and its storage the bearing plate 45 relates. The one shown in Fig. 10 Support arm 11 'is in its wing-side section 15 and its cranked section 16 is substantially identical with the support arm 11 shown in FIG. 2 and in the same Way like this in the faceplate groove and Espagnolette groove of the sash 3 inserted and attached. The bearing-side section 13 'forms one Guide section of reduced width in which a Longitudinal slot 91 with cross-shaped extension 91a is formed (see Fig. 13). The horizontal leg 57 'of the bearing bracket 51 is a U-guide open at the bottom shaped which the bearing-side portion 13 'of Carrying arm 11 slidably receives.

In the top wall of the horizontal leg 57 ', i.e. the U-guide, a guide opening 93 is formed (Fig. 13), in which a sliding block 95 is guided by the in vertical leg 53 of the bearing bracket 51 mounted Adjustment screw 65 is penetrated and with it in Thread engagement is available, preferably via one of the self-tapping adjusting screw 65 cut thread. The sliding block 95 has at the top two lateral projections 95a, which on inclined surfaces 93a the guide opening 93 rest. The down on it adjoining shaft of the sliding block 95 has one Cross-section that he form-fit the cruciform Extension 91a of the bracket 11 'fills, so that the Support arm 11 'over the sliding block 95 acting as a driver is connected to the adjusting screw 65 and by turning the adjusting screw 65 along the U-guide in the horizontal Leg 57 'of the bearing bracket 71 can be adjusted.

The sliding block 95 is extended downward like a shaft bears below the bearing-side section 13 'of Support arm 11 'a guide piece 97 which, as in Fig. 10th shown in the rebate surface groove when the fitting is installed 21 engages the vertical fold surface of the sash 3 (Fig. 10), in their serving as drive rod groove deeper groove part 24. The guide part 97 thus supports the Bearing bracket 51 and thus the bearing-side section 13 ' of the support arm 11 'on the sash 3 against perpendicular to Forces acting from the wing plane, but is in the Folding surface groove 21 vertically displaceable, so that the bearing-side section 13 'of the support arm 11' not there is prevented from perpendicular to the casement 3 move and thus one at the corner bearing 5 (Fig. 1) made to follow the vertical adjustment.

The described support of the bearing end 13 'of Support arm 11 'in the vertical groove is achieved without the support arm 11 'being rectangular at its end bent leg, as in the Embodiment according to FIGS. 2 to 10 is present. The Support arm 11 'can against a conventional extension arm for Tilt-and-turn windows can be replaced, if that bearing end is formed in the same way as described for the support arm 11 and in particular in Fig. 13 has been shown. When inserting an extension arm the guide piece 97 is omitted and a sliding block 95 used, which is much shorter in the vertical direction is designed so that its shaft is not up to the Extends the area of the rebate surface groove of the casement.

Sliding block 95 and guide piece 97 can be made of suitable Plastic.

The vertical leg 53 of the bearing bracket 51 engages behind the bearing plate 45 of the movable bearing part 39 and is on this in the same way by means of rivet pin 69 and spring washer 71 rotatably and displaceably against spring force, as in the embodiment according to FIGS. 2 to 8 has been described. The interacting snap-in projections and snap-in notches for setting the bearing angle 51 in one of the two positions rotated by 180 ° relative to Mounting plate 45 are, however, different from that previous embodiment designed. On the vertical leg 53 of the bearing bracket is on that of the mounting plate 45 a single latching projection 78 in the center of the facing surface trained, optionally in one of two Snap openings 76 can snap into the bearing plate 45 centered and symmetrical above and below the Bearing opening 74 for the rivet pin 69 are punched out. Each latch opening 67 is one to the free edge of the Mounting plate 45 open guide groove 80 upstream, which leads the locking projection 78 of the bearing bracket 51 and him initially deforming and then relaxing the Spring washer 71 in the respective snap-in opening 76 snaps into place. In addition, 51 are on the bearing bracket hook-shaped support projections 89 are provided which Bearing plate 45 over and at its upper edge reach behind like this for the hook-shaped Snap-in projections 77 of the embodiment according to FIGS. 2 to 8 has been described.

A third embodiment is illustrated in FIGS. 15 to 18 described. With her is below the support arm 11 " Filler piece 101 is provided, which is preferably made of plastic is made. The filler 101 is designed so that it in the upper horizontal groove 21 of the Casement 3 is used and this in full depth fills. Has at the end facing the pivot bearing 9 the filler 101 has a bend 103, which in the vertical groove of the sash 3 engages. The wing-side section 15 of the support arm 11 "is on one suitable location, designated 105 in FIG. 15, by means of a screw (not shown) through Bores of the support arm 11 'and the filler 101 therethrough is screwed into the bottom of the groove 21 with which Sash frame 3 firmly connected. In this area is the Support arm 11 "preferably, as shown, in the form of a transverse bead 107 bent to its flexibility to improve in the vertical direction. Left of the Bolting point 105 is the support arm 11 "in the same Way as the support arm 11 shown in FIG. 2 and is formed in the area of its U-shaped bent end 23 by a further screw connection fastened in the drive rod groove.

The one to the right of the screw connection 105 and bead 107 Part of the support arm 11 "is due to its flexibility, especially in the area of the bead 107 and the cranked Section 16, perpendicular to the casement 3 movable to adjust movements of the wing, which in the lower corner bearing 5 (Fig. 1) are caused to follow can. During this vertical movement the support arm is 11 " passed through the filler 101. For this purpose, the Filler 101 on its top a guide projection 109 on which a guide opening 111 of the support arm 11 " be upheld. In the upper area is the Guide projection 109 U-shaped with two legs trained, the outwardly projecting, beveled Have snap-in projections 113. When inserting into the Guide opening 111 of the support arm 11 "are U-legs of the Guide tab 109 compressed until the tabs 113 behind the longitudinal edges of the rectangular guide opening 111 engage so that the filler 101 on the support arm 11 " is captively secured. The filler 101 has one second passage opening 115 for a second Fixing screw with which it is at the bottom of the rebate groove 21 can be attached. A correspondingly large one Access opening 117 in the support arm 11 "allows access this mounting screw.

The bearing-side section 13 of the support arm 11 ", the Bearing bracket 51 and the pivot bearing 9 with the movable Bearing part 39 and the support plate 45 are essentially identically designed as in the embodiment according to FIG. 10 to 13 and will therefore not be repeated in detail explained. It should only be mentioned that the extension 91a of the slot 91 of the support arm 11 "engaging Sliding block 95 'is dimensioned so short in the vertical direction, that it does not protrude into the groove of the casement 3 and also not a guide piece like the guide piece 97 in Fig. 10. This is possible because of the Sliding block 95 no management function for the vertical Movement of the support arm 11 "exerts, since this guidance from the Guide projection 109 of the filler 101 is adopted. If instead of the support arm 11 "for a rotary wing Extension arm for a tilt and turn sash (of course without Filler 101) are connected to the bearing bracket 51 the sliding block 95 can therefore remain unchanged can be used and does not need against another Sliding block to be replaced.

   characterised in that the pivot bearing is formed resiliently flexible in its radial direction so as to make possible the displacements of the bearing angle member (51) relative to the bearing plate (45).
2. A fixture according to Claim 1, characterised in that a spring ring (71), which is elastically radially deformable, is provided in the pivot bearing and engages in bores of the bearing angle member and the support plate.
3. A fixture according to Claim 1 or 2, characterised in that guides (79,80) are provided on the bearing plate (45) or on the bearing angle member (51), which guides cooperate with the at least one guide projection so as to constrain, during the rotating movement of the bearing angle member (51) relative to the bearing plate (45), the transverse displacement of the bearing angle member (51) relative to the bearing plate (45) with elastic deformation of the spring ring (71), which displacement is necessary for the engagement of the projections (77,78) into the recesses (75,76).
