Description

The invention relates to a fitting for forcibly tilting and parallel sashes that can be locked and locked in the closed or shutdown position Wing flap of windows, doors or the like with the characteristics of Preamble of claim 1.

It is known to have wings of the type in question on the top edge and on the lower edge to be supported in each case by extension arms, with their one End connected with running links or running elements, which in or ver on guide or running rails attached to the inside of the frame are guided. These extension arms are usually on one Cover rail pivoted, which in the area of the sash lying and used to hold elements of the actuating linkage Profile groove of the wing covers (see. DE-PS 30 50 971). In this known Training the extension arm is designed so that it has no opening or recesses in the area of the wing flap from its in the wing folded end up to that reaching to the guide rail or the like End runs.

In other such designs (see. DE-PS 26 48 344) is in Be range of the wing profile groove on the cover rail or a corresponding Ab Extension arm articulated by a perforation or off take the wing overlap to the outside. The extension arm points a right-angled control curve, which is open to the outside and outside half of the profile groove of the wing. A control cam is with the help of a Bracket with the ends of the operating linkage on both sides of the fitting connected that the control cam arranged on the bracket with the actuator supply rod is movable longitudinally. With another out management form (see. DE-OS 26 33 369) is the extension arm with the help of a loading fastening plate attached to the side profile next to the profile groove and has a closed rosette-like control in the area above the profile groove curve in which a directly connected to the operating rod Control pin engages (see also DE-PS 27 00 598).  

The latter two embodiments are only for parallel adjustable sliding doors determined and suitable. For additional actuation, e.g. B. for tilting the wing, the lengths of the cam sections are sufficient not from. The latter two training courses also require special bearing bushes engaging deeply in the wing profile for receiving corresponding Articulation pins with which the extension arms can be swiveled in the hollow profiles are mounted to the sash weight on the frame, which consists of hollow profiles exists to be able to transmit safely.

To avoid these disadvantages, it is known to tilt for and parallel adjustable and sliding wing extension arms with additional control arm provide (see. DE-PS 40 16 341). If, however, a separate mounting plate for the extension arm is necessary, as is the case with the fitting according to DE-OS 26 33 369 is the case, the height of the wing rebate is no longer sufficient for the Housing an additional control arm.

It is an object of the invention to provide a fitting for forcibly tilting and parallel adjustable sashes that can be locked in any open position with sash flaps of windows, doors or the like, with the features of the generic term of the An Say 1 so that despite the several controllable open positions lungs of the wing an additional control arm is not required that the Fitting is also suitable for larger sash weights and without major changes Changes in the profile of the casement easily and easily installed and ge customary locking or actuating linkage can be connected.

This object is achieved by the teaching of claim 1.

The wing arms supporting the wing are each in one piece, i. H. without additional Lichen control arm or the like. They are preferably for the top one Wing edge provided, but can also be used to support the Wing are used on the lower edge. The ones to be included Forces become reliable due to the usual to take up the boom Serving profile groove spanning mounting or bearing plate included can be attached directly to the profile and on which both the connecting rods element can be held and guided as well as the extension arm stored directly is without the need for additional storage means built into the profile of the wing. The actuating linkage acts directly on the drive rod element attached control cam or the like. That through a slot in the bearing plate  engages with a control curve open towards the flap of the wing. This can therefore take a comparatively long time to close and open the wing Have cam sections, which in each position of the wing in the area the width of the bearing plate remain, so that neither for this nor for Lead out the opening arm recesses or openings on Overlap of the wing must be incorporated.

The control curve, which is open to the side, preferably has straight curve sections of great length, which together form an angle well above 90 ° lock in.

The new fitting allows that despite the relatively long needed Push lines for controlling the various positions of the boom and of the wing all parts of the fitting remain behind the wing overlap, so that this does not require processing.

For leading the cranked extension arm out of the area of the sash it is necessary to open the seal provided on the wing flap to interrupt a corresponding area.

This can advantageously be avoided if the one articulated on the bearing plate Section of the extension arm together with the bearing plate by one only relatively narrow slot of the flap led out of the fold area and the extension arm is only cranked outside the rollover.

This requires machining the casement. However, the intervention is only slight, as there is a profile cut-out, as for swinging out Arm of the above-mentioned DE-PS 26 48 344 does not need. Besides, can the narrow slot in light metal or plastic profiles with the anyway existing punching tool can be produced, which for the arrangement of the usual gear handles is required.

The bearing plate and extension arm are led out through the narrow slot leads to the pivot point of the extension arm in front of the plane of the wing frame comes to rest and so the control cam over a particularly large one Lever arm can exert a particularly favorable force on the extension arm. Of the Slot and / or the extension arm and the bearing plate can if necessary a cover profile can be covered visually.  

For the large length of the control curves, the rear is also advantageous Cutting the wing overlap in the usual hollow profiles of the wing with exploited.

The invention is based on schematic drawings several embodiments explained in more detail.

In the figures, the frame is denoted by 1 and the profiled hollow frame for the wing by 2 . In Fig. 1 is indicated in the area of the sash rebate to running, largely standardized profile groove 15 , in the te Stangenelemen or the like. A conventional actuating linkage are arranged, which is indicated in FIGS. 1 to 3 by the actuating lever. With the help of this actuating linkage, upper and lower opening arms 8 and 9 of fittings can be operated, which are the subject of this description.

The free ends of the upper extension arms 8 have running members which engage in a running rail 4 mounted on the inside 46 of the frame 1 . The free ends of the lower extension arms 9 are articulated to running members, as indicated in FIG. 1, which are wagon-like or sledge-like and can be moved parallel to the plane of the frame on a running rail 6 provided on the frame 1 .

FIGS. 4 and 5 show, on an enlarged scale sections through the upper portion of the frame and sash frame. The section according to Fig. 5 shows the formation in the region outside of the fittings 5, while Fig. 4 represents the section in the region of the fitting 5.

The fittings 5 for the upper wing edge are shown and described in more detail below. However, it is expressly pointed out that the basic features of the fittings, which are of interest here, can accordingly also be provided for the fittings for the lower wing edge.

In Figs. 4 and 6, the portion of the airfoil can be seen, having the usual and mostly standardized fitting groove 15 for the actuating linkage. The width of this profile section is indicated at 43 in FIG. 5, the width being measured from the inner surface 11 of the wing flap 10 . In areas outside the fitting, the actuating members 16 of the actuating linkage are supported and guided in the profile groove 15 . The hardware groove can be undercut for this purpose. In this area, the hardware groove can also be covered on the outside by a cover rail.

In the area of each fitting 5 , a special linkage element 17 is seen which, as shown in FIGS. 6 and 7, can be easily and quickly coupled via simple coupling pins 30 and corresponding bores with the subsequent linkage members 16 . The linkage element 17 is held directly on the underside of a mounting or mounting plate 18 and is guided in a longitudinally displaceable manner. The bearing plate 18 engages over the fitting groove 15 and, according to its width 41 , takes up practically the entire free width of the section of the sash frame profile facing the fitting groove 15 , as can be seen in particular from FIG. 4, but also from FIGS. 6 and 7. Laterally next to the fitting groove 15 , a flat lying section 20 of the extension arm 8 is pivotably mounted on the upper side of the bearing plate 18 with the help of the bearing pin 24 . From the section 20 of the extension arm 8 has a width 42 which does not exceed the width 41 of the bearing plate 18 .

The bearing plate 8 has a longitudinal slot 31 in the center above the fitting groove 15 , through which an actuating pin 25 engages, which is connected directly and firmly to the rod element 17 . The section 20 of the extension arm 8 has in the area of the slot 31 a control curve 32 which is open towards the side of the flap 10 of the wing. This consists in the illustrated exemplary embodiment from three curve sections 33 , 34 and 35 . The two outer curve sections 33 and 34 are essentially rectilinear and form an angle of approximately 135 ° with one another. The angle should be significantly greater than 90 ° and can be between 95 ° and 150 °, but preferably between 120 ° and 140 °. In both limited by a fixed to the bearing plate 18 stop 40 pivoting positions of the set-8 one each is the straighter the cam portions 33, 34 the slot in alignment with the remote from the flap 10 of the wing boundary edge of the longitudinal parallel and preferably 31st The middle curve section is circular arc and so angeord net that in each case the transition to the adjacent rectilinear section 33 or 34 in one of the end positions of the extension arm 8 is approximately centrally above the longitudinal slot 31 , as can be seen from FIGS. 6 and 7 without further notice .

Due to this design, the straight curve sections receive an effective length 45 , which is particularly large and is sufficient for the control of the various positions: closed position, tilt position, position in parallel and ensures that the extension arm 8 in each of these positions by the interaction of the curve sections the control pin 25 is locked so that the wing can not be moved by attacking external forces.

When applying the invention to the lower arms can after Release the lower end of the wing or pull it off using the Actuating rod can be pushed off the frame.

It can be seen that the extension arm 8 has an outer section 22 which is articulated to the running member 23 and which is connected to the section 20 resting on the bearing plate 18 by an angled section 21 lying behind the wing flap 10 in the closed position of the wing is. This training allows to bring the extension arms without 10 recesses or openings must be incorporated in the rollover.

Also, Figs. 6 and 7 show that, in spite of the great length of the individual sections of the set-NEN curve remain the entire cam in any position of the blade within the width 41 of the bearing plate 18. In this respect, too, it is not necessary to process the wing flap during assembly.

The actuating section 17 can hold and be guided on the bearing plate 18 with the aid of the fastening elements 19 serving to fasten the bearing plate to the profile GE. For this purpose, the rod section 17 has corresponding longitudinal slots.

In the embodiment shown in FIGS. 8 to 10, the control cam 55 of the extension arm 51 , which is open to the side, points away from the inner surface 64 of the wing flap 63 of the wing 40 . The extension arm is mounted with a section 52 resting on the upper side of the bearing plate 45 in the immediate vicinity of the wing flap 63 between the latter and the vertical longitudinal median plane 41 of the profile groove 42 and the actuating rod 43 .

The bearing plate 45 is fastened to the profile of the wing 40 by means of screw 46 on the bottom of the profile groove 42 . On the underside of the bearing plate 45 , a drive rod element 44 is held and guided displaceably and forms a preassembled construction unit with the other parts provided on the bearing plate 45 .

The control cam 55 in turn has two straight curve sections 56 and 57 , the length 62 of the section 56 being substantially greater than the effective length 61 of the section 57 . A curved cam section 58 is provided between these. On the pivot point 53 of the actuating arm 51 from the opposite side of the bearing plate 45 , a limit stop 50 is provided, which interacts with the cam sections 56, 57 in the manner already described.

As is apparent esp. From Fig. 10, the longitudinal slot is offset 60 in the support plate 45 with respect to the vertical longitudinal center plane 41 of the profile 42 to the side facing away from the wing flap 63 side. The control cam 49 is connected to the drive rod element 44 via a cranked element 48 in such a way that the control cam 49 is clearly offset in the same direction as the longitudinal slot 60 with respect to the vertical longitudinal center plane 41 of the profile groove 42 . It is designed like a head and is supported on the top of the bearing plate 45 on one edge region of the longitudinal slot 60 .

It can be seen from Fig. 8 that in the closed position of the wing, the contact point between the control cam 49 and cam 55 lies in a region which lies between the articulation points provided at the ends of the extension arm 51 , of which only the articulation point 53 on the bearing plate 45 is shown.

The extension arm 51 is in turn cranked out parallel to the rollover 63 , so that in this embodiment the wing rollover 63 can be formed practically without recesses or openings.

Since the effective length of the curve section 57 is less than the effective length of the other straight curve section 56 , in this embodiment, the bearing plate 45 can be formed somewhat narrower than the overall width of the profile groove 42 having the section of the casement profile if required. However, this is not critical, since in the direction away from the wing flap there is sufficient space for a longer cam section 57 (see FIG. 10).

The described relative position of the control cam in the closed position ( FIG. 8) of the opening arm leads to a significantly improved and more durable locking of the opening arm in the closed position of the wing.

The embodiment according to FIGS. 11 and 12 differs from that according to FIGS. 8 to 10 mainly in that the wing 70 has a narrow slot 78 in its flap 71 through which the bearing plate 74 and the section 76 of the extension arm articulated thereon 75 reach out of the profile area in front of the plane of the wing 70 . There, with the formation of a large power arm of length 84, the articulation point 77 as well as the cranking of the extension arm 75 .

In this embodiment, the control cam 81 and the longitudinal slot 80 can be arranged centrally to the groove 72 and the actuating rod 73 . For the control curve with its cooperating on a stop 82, the portions 8 already applies to the embodiment according to FIG. 10 to set forth.

It can be seen that the seal provided on the flap need not be broken. It can also be seen that the slot 78 is only very narrow and can easily be punched out with a tool that is required for other purposes anyway.

Slot 78 and / or bearing plate 74 and extension arm 75 can be visually covered by a profile 95 .

FIG. 13 shows, in a representation corresponding to FIG. 11, the application of the fitting in the lower region of the wing 70 . The extension arm 93 articulated on the bearing plate 92 can therefore be articulated on a lower carriage or carriage 91 which is guided on the frame 90 .

In the embodiment of Fig. 11 to 13 results in addition to the advantages of avoiding an interruption of the window seal at the flap and the even greater power transmission, the advantage that the outside remaining with its bend forward of the wing stay arm with the bearing plate 74 as a preassembled unit from the outside through the slot in the wing flap and can be coupled with the control cam.
